Description
Technical field
The invention belongs to shedding device of weaving machine technical fields, and in particular to a kind of lower opening company of wide cut shuttleless loom
Rod structure.
Background technique
Shedding device of weaving machine is configured at the lower section of loom, then referred to as lower opening device, the lower opening device
The connecting rod of structural system is known as lower opening connecting rod, and vice versa.The lower opening connecting rod and routine of wide cut shuttleless loom
The essential distinction of the lower opening connecting rod of breadth shuttleless loom can be found in " the positive type company of Chinese patent CN2895458Y recommendation
The specification and its attached drawing of bar underneath type Hui Zong mechanism ".
Pass through the reading to above patent document and combines professional general knowledge it is found that the fabric width that shuttleless loom adapts to is got over
Greatly, the length of lower opening connecting rod is also corresponding more grows (the same example of overhead opening connecting bar).Opening connecting bar is longer, to rigid requirements
It more is harsh.That is if the rigidity of interminable opening connecting bar cannot ensure, amount of deflection (or bending) can be generated,
And once there is bending situation, it just can not make heald frame and connecting rod keeping parallelism, the movement effects of heald frame, which will receive, to be seriously affected very
To the normal braiding for undermining heald frame and influence loom.
The technical information of the opening connecting bar structure of shuttleless loom can be seen in disclosed Chinese patent literature, typically such as
" the high speed loom connecting rod ASSY " that CN204097666U is provided, by connector, by two connecting rods, (patent claims " in two the patent
Arm ") connection, in one end far from connector of two connecting rods and on the connectors and it is located at each hinged knife in middle part of connector
Piece (industry is also referred to as " rocker arm "), connector includes upper cover, lower cover, U-shaped plug-in unit and clamping screw, and upper cover and lower cover two sides pass through
Bolt fixture is connected with U-shaped plug-in unit, and the so-called middle arm of the connecting rod i.e. patent is inserted directly into U-shaped plug-in unit and passes through locking screw
Bolt is fixed connecting rod and U-shaped plug-in unit (for details, reference can be made to the 0015th section of the patent specification).The connector of the patent is substantial
The effect of intermediate connecting rod is acted as, and the patent structure can be suitably used for wide cut shuttleless loom, but there are following shortcomings: its
One, due to using a pair of U-shaped plug-in unit, and since U-shaped plug-in unit has elasticity, thus the rigid connection effect between connecting rod is difficult
To ensure；Second, due to U-shaped plug-in unit in the connecting rod chamber of insertion connecting rod after be difficult to reach mortise-tenon joint requirement, thus connecting rod exists
Stationarity in motion process is difficult to ensure.
CN207904457U introduction has " connecting rod on rapier loom and air-jet loom ", which is easy for connecting rod two end
It damages and is conveniently replaceable proposition, be that connecting rod is divided into three parts, is i.e. middle part and two ends, two ends respectively pass through connection
Block is connect with middle part, that is to say, that is connect at middle part with end by link block, to release end portion connection block after end is damaged
Connection relationship, and the end of damage is replaced, then connect that (for details, reference can be made to the patent specifications with link block again
0023 section).Complex root connecting rod is implemented rigid connection and is suitble to Looms it follows that the CN207904457U is not provided
Requirement enlightenment.
It is famous that improved Chinese patent Granted publication has been made to French Patent (FRP) FR-A-2676467 and FR-A-2776307
" draw-off mechanism and its manufacturing method and the loom with this mechanism " that number CN1303270C is introduced is with regard to swing connecting bar and connecting rod
The connection of end be described in detail.Swing connecting bar above-mentioned is essentially above mentioned blade or rocker arm, and preceding
The connecting rod stated is essentially the connecting rod in CN204097666U above, thus do not provide equally complex root connecting rod is such as left,
The enlightenment for being rigidly connected and meeting the requirement of Looms is implemented in right connecting rod and intermediate connection.
As far as the applicant is aware, prior art is generally hinged with left and right connecting rods by intermediate connecting rod in hinged way, but as before
It states, the undesirable situation that hinge joint position is arched upward upwards or collapsed downwards is hingedly appeared in, because of hinge joint portion
Position arches upward upwards and collapses can make heald frame during the motion downwards, and length direction can not be with connecting rod keeping parallelism.
For above-mentioned prior art, it is necessary to improved, thus the applicant made positive and beneficial design and
Form technical solution described below.
Summary of the invention
Task of the invention lies in provide one kind help each other to realize left and right connecting rods and intermediate connecting rod it is good just
Property connection and be avoided and the uncertain variation arched upward or collapsed etc occur in connecting portion during the work time and ensure
The lower opening link mechanism of the wide cut shuttleless loom of the smooth motion effect of heald frame.
The task of the present invention is in this way to complete, a kind of lower opening link mechanism of wide cut shuttleless loom, including
