the trigger sleeve is slidably arranged in the accommodating cavity;
the conveying tables are slidably arranged in the accommodating cavities, second elastic elements used for driving the conveying tables to move upwards are arranged between the conveying tables, and the upper ends of the conveying tables are used for bearing the replaceable units;
the trigger mechanism is provided with a claw and a third elastic element, the claw is hinged and installed in the containing cavity, and the third elastic element is used for forcing the claw to limit the upward movement of the conveying table and enabling the second elastic element to be in a compressed state; when the non-replaceable unit moves downwards, the locking sleeve is in contact with the trigger sleeve and gradually departs from the locking position, the trigger sleeve pushes the clamping jaw to deflect so as to remove the limitation on the conveying table, and the second elastic element releases the elastic force so as to push the conveying table to move upwards, so that the replaceable unit on the conveying table reaches the mounting position of the mounting seat; when the non-replacement unit moves upwards, the first elastic element pushes the locking sleeve to lock the replaceable unit at the installation position of the installation seat.
The locking position can be left automatically to the in-process that the unit was not changed in this scheme moving down to the locking sleeve can be got into smoothly to the unit of change the mounted position of mount pad, makes the jack catch remove the restriction to carrying the platform automatically through triggering the cover afterwards, and second elastic element promotes to carry the platform rebound in the same place, pushes the mounted position of mount pad with the unit of not changing, thereby realizes the automatic installation of nozzle, improves production efficiency.
Furthermore, the bottom end of the mounting seat is provided with an inner cavity matched with the replaceable unit, the peripheral surface of the mounting seat is penetrated with a plurality of windows communicated with the inner cavity, and locking balls are arranged in the windows;
the replaceable unit is inserted into the inner cavity and is located at the installation position of the installation seat when the locking ball is opposite to the locking groove, and when the locking sleeve is located at the locking position, the locking ball is pushed by the locking sleeve until one part of the locking ball is located in the window, and the other part of the locking ball is located in the locking groove;
once the replaceable unit is inserted into the inner cavity, only the freedom degree of axial movement is left, and in a normal state, the first elastic element pushes the locking sleeve to the locking position, the locking sleeve at the locking position can push the locking ball to be embedded into the mounting seat and the locking groove at the same time, so that the replaceable unit is axially fixed in the inner cavity, and the replaceable unit and the non-replaceable unit are completely fixed.
In order to improve the compactness of the structure and facilitate the manufacture, further, the locking sleeve is sleeved outside the mounting seat, a locking surface which is inclined outwards from top to bottom is arranged at the position, above the locking ball, of the inner peripheral wall of the locking sleeve, an unlocking cavity is formed between the position, below the locking surface, of the inner peripheral wall of the locking sleeve and the outer peripheral wall of the mounting seat, and when the locking sleeve is located at the locking position, the locking ball is pushed to the inner peripheral surface which is protruded out of the inner cavity by the locking surface of the locking sleeve;
the wall thickness between the part of the inner peripheral surface of the inner cavity, which is positioned at the window, and the part of the outer peripheral surface of the mounting seat, which is positioned at the window, is less than the ball diameter of the locking ball;
when the locking sleeve of the non-replacement unit presses the trigger sleeve, the locking sleeve overcomes the elastic force of the first elastic element to move upwards, the locking ball is separated from the locking surface and is opposite to the unlocking cavity, one part of the locking ball can enter the unlocking cavity so as not to protrude out of the inner circumferential surface of the inner cavity, and therefore axial fixing of the replaceable unit is released, and the non-replacement unit can freely enter and exit the inner cavity.
In order to prevent the first elastic element from being excessively compressed to reduce the service life, the mounting seat is provided with a step surface which is arranged above the locking sleeve and is used for the locking sleeve to abut against; when the locking sleeve moves upwards to be in contact with the step surface of the mounting seat, the maximum stroke is reached, and the first elastic element is prevented from being compressed excessively.

Furthermore, the upper surface of the clamping jaw is a second inclined surface matched with the trigger sleeve, and when the clamping jaw limits the upward movement of the conveying table, the second inclined surface is inclined inwards from top to bottom; so that the downward linear motion of the trigger sleeve can be converted into the rotation of the claw.
In order to improve the flexibility of movement, further, the bottom end of the peripheral wall of the trigger sleeve is provided with a matching surface which is positioned above the clamping jaw and used for pushing the second inclined surface of the clamping jaw to deflect, and the matching surface is inclined inwards from top to bottom; thereby facilitating the trigger sleeve to drive the jaws to rotate outwardly to free the table.

Furthermore, a fourth elastic element for pushing the trigger sleeve to move upwards is arranged between the trigger sleeve and the accommodating cavity; therefore, when the non-replacement unit moves upwards, the trigger sleeve automatically resets under the action of the fourth elastic element.
In order to prevent the clamping stagnation, the elastic force of the fourth elastic element is larger than that of the first elastic element; therefore, when the non-replacement unit moves downwards, the locking sleeve overcomes the elastic force of the first elastic element in advance and moves upwards to leave the locking position, and then the locking sleeve moves downwards along with the non-replacement unit to enable subsequent actions to be carried out in sequence, so that clamping stagnation caused by the fact that the clamping jaws release the conveying table in advance is prevented.
In order to prevent the replaceable unit from being mounted in place or separated from the replaceable unit, further, when the trigger sleeve pushes the clamping jaw to deflect so as to remove the limitation on the conveying table, the sum of the displacement of the replaceable unit moving to the mounting position of the mounting seat and the displacement of the non-replaceable unit restoring the locking sleeve to the locking position in the lifting process is less than or equal to the stroke of the second elastic element driving the conveying table to move upwards through elasticity;
therefore, the conveying table can always support the replaceable unit before the locking sleeve is restored to the locking position, the situation that the replaceable unit is not installed in place or separated from the replaceable unit in the process that the non-replaceable unit rises is prevented, and the locking sleeve can smoothly lock the non-replaceable unit on the mounting seat.

The invention also provides dispensing equipment which comprises the nozzle component mounting platform.
The invention has the beneficial effects that: according to the nozzle assembly mounting platform, the locking sleeve can be automatically separated from the locking position in the process of moving the non-replacement unit downwards, so that the replaceable unit can smoothly enter the mounting position of the mounting seat, then the clamping jaw automatically releases the limitation on the conveying table through triggering the sleeve, the conveying table is pushed upwards by the second elastic element along the trend, and the replaceable unit is pushed into the mounting position of the mounting seat, so that the automatic mounting of the nozzle is realized, the production efficiency is improved, therefore, when the base is provided with the plurality of accommodating cavities, a nozzle library with the plurality of replaceable units can be selected equivalently, various different production requirements are realized, the non-replacement unit only needs to perform linear movement in the mounting process, and the control logic is simple.

When the trigger sleeve 4 pushes the claw 71 to deflect so as to remove the limitation on the conveying table 5, the sum of the displacement of the replaceable unit 2 moving to the installation position of the installation seat 11 and the displacement of the non-replaceable unit 1 restoring the locking sleeve 12 to the locking position in the lifting process is less than or equal to the stroke of the second elastic element 6 driving the conveying table 5 to move upwards through elasticity; therefore, the conveying table 5 can always support the replaceable unit 2 before the locking sleeve 12 is restored to the locking position, the situation that the replaceable unit 2 is not installed in place or separated in the process that the non-replaceable unit 1 ascends is prevented, and the locking sleeve 12 can smoothly lock the non-replaceable unit 1 on the installation seat 11.
In the present embodiment, the first elastic element 13, the second elastic element 6 and the fourth elastic element 8 may all adopt compression springs, the elastic direction of the second elastic element 6 and the fourth elastic element 8 is preferably consistent with the axial direction of the conveying table 5, and the elastic direction of the first elastic element 13 is parallel to the axial direction of the inner cavity 11a of the mounting seat 11.
The operating principle of the nozzle component mounting platform in the embodiment is as follows:
1) as shown in fig. 11 and 12, in the initial state, the replaceable units 2 of different specifications, i.e. the nozzles 23 of different specifications, can be respectively placed on the conveying tables 5 in the accommodating cavities 31 on the base 3; under the action of the third elastic element 72, the first inclined surface 71a at the lower end of the claw 71 is kept attached to the limiting surface 5a at the upper end of the conveying platform 5, the conveying platform 5 is limited to move upwards, and the second elastic element 6 is in a compressed state;
2) the mounting seat 11 of the non-replacement unit 1 is fixed on the application equipment, the application equipment can drive the non-replacement unit 1 to move up and down, and the specific installation process is as follows:
first, as shown in fig. 11 and 12, when the application device drives the non-replaceable unit 1 to move to the upper side of the accommodating cavity 31, the mounting seat 11 of the non-replaceable unit 1 is kept coaxial with the fixing member 21 of the replaceable unit 2;
then, the application device drives the non-replacement unit 1 to move from top to bottom, the lower surface of the locking sleeve 12 is in contact with the upper surface of the trigger sleeve 4, and because the elastic force of the fourth elastic element 8 is larger than the elastic force of the first elastic element 13, the first elastic element 13 is compressed first until the locking sleeve 12 is separated from the locking position relative to the mounting seat 11 and moves to be in contact with the step surface 11c of the mounting seat 11, and then the mounting seat 11, the locking sleeve 12 and the trigger sleeve 4 move downwards synchronously, and the matching surface 4a at the bottom of the trigger sleeve 4 is in contact with the second inclined surface 71b at the upper end of the claw 71 in the descending process of the trigger sleeve 4, so that the claw 71 rotates around the hinge point of the claw 71 until the first inclined surface 71a of the claw 71 is separated from the limiting surface 5a at the upper end of the conveying table 5, and the claw 71 does not have a braking effect on the conveying table 5 any more;
subsequently, as shown in fig. 13 and 14, the application device can stop the movement of the non-replaceable unit 1, and since the delivery table 5 is no longer subjected to the braking effect of the pawl 71, the second elastic element 6 pushes the delivery table 5 and the replaceable unit 2 thereon upwards until the fixed part 21 of the replaceable unit 2 is inserted into the cavity 11a of the mounting seat 11 and reaches the mounting position of the mounting seat 11;
finally, the application device drives the non-replaceable unit 1 to move upwards, the second elastic element 6 can continuously support the replaceable unit 2 in the process of moving upwards until the locking sleeve 12 of the non-replaceable unit 1 returns to the locking position, and the locking ball 14 is pushed to be embedded into the locking groove 21a of the fixing piece 21 of the replaceable unit 2, so that the situation that the replaceable unit 2 is not installed in place or separated in the process of lifting the non-replaceable unit 1 is prevented, the locking sleeve 12 is ensured to smoothly lock the non-replaceable unit 1 on the mounting seat 11, and automatic installation of the non-replaceable unit 1 is achieved.
As for the way of detaching the replaceable unit 2 from the non-replaceable unit 1, this embodiment does not limit this, and it may be manually detached or automatically detached, for example, the automatic detachment may be that an application device drives the non-replaceable unit 1 to move downward, so that the trigger sleeve 4 abuts against a member and moves upward relative to the mounting base 11, the unlocked replaceable unit 2 automatically breaks away from the inner cavity 11a under its own weight, and a dedicated recovery mechanism of the non-replaceable unit 1 may also be designed.
In this embodiment, the non-replacement unit 1 can automatically move the locking sleeve 12 away from the locking position in the downward movement process, so that the replacement unit 2 can smoothly enter the installation position of the installation seat 11, and then the jaw 71 automatically releases the limitation on the conveying table 5 through the trigger sleeve 4, the second elastic element 6 pushes the conveying table 5 to move upwards along with the movement, so that the replacement unit 2 is pushed into the installation position of the installation seat 11, thereby realizing the automatic installation of the nozzle 23, and improving the production efficiency, so that when the plurality of accommodating cavities 31 are arranged on the base 3, a nozzle library with a plurality of replaceable units 2 which can be selected is equivalently formed, so that various different production requirements can be met, and the non-replacement unit 1 only needs to execute the movement in the linear direction in the installation process, and the control logic is simple.
