Detailed Description

In order to make the objects, technical solutions and advantages of the present application more apparent, the technical solutions of the present application will be clearly and completely described below with reference to specific embodiments of the present application and corresponding drawings. It will be apparent that the described embodiments are only some, but not all, embodiments of the application. All other embodiments, which can be made by those skilled in the art based on the embodiments of the application without making any inventive effort, are intended to be within the scope of the application.

In this document, "schematic" means "serving as an example, instance, or illustration," and any illustrations, embodiments described herein as "schematic" should not be construed as a more preferred or advantageous solution.

For the sake of simplicity of the drawing, the parts relevant to the present application are shown only schematically in the figures, which do not represent the actual structure thereof as a product. In addition, for simplicity and ease of understanding, components having the same structure or function in some of the figures are shown schematically only one of them, or only one of them is labeled.

The following describes in detail the technical solutions provided by the embodiments of the present application with reference to the accompanying drawings.

Fig. 1 is a schematic exploded view of an exemplary embodiment of a movable clasp assembly for a filling machine jaw. Fig. 2 is a schematic view illustrating a combined structure of the movable hook assembly of the clamping jaw of the filling machine shown in fig. 1.

Fig. 1 and 2 show a pair of filling jaws 30 for use on a filling machine, the pair of filling jaws 30 being relatively movable in a gripping direction X indicated by the arrow in the figures. Those skilled in the art will appreciate that only left hand filling jaw 30 may be moved, only right hand filling jaw 30 may be moved, or both left hand filling jaw 30 and right hand filling jaw 30 may be moved, as long as the relative movement of a pair of filling jaws 30 is satisfied, as desired.

A pair of filling jaws 30 are each provided with a sealing device 40 (the sealing device on the left filling jaw 30 is shown hidden) for performing heat sealing of the package or the like. In order to enable the packaging device 40 on the pair of filling machine clamping jaws 30 to cooperate with each other to clamp the package when the pair of filling machine clamping jaws 30 are relatively moved to a clamping position along the clamping direction, a set of hook assemblies may be provided on each side of the packaging device 40 to help achieve a tightly clamped state.

In the pair of filling jaws 30 shown in fig. 1 and 2, the left filling jaw 30 is provided with a fixed hook 20 on both sides of the packaging device 40, and the right filling jaw 30 is provided with movable hook assemblies 10 on both sides of the packaging device 40, wherein each movable hook assembly 10 includes a movable hook 12 and a fixing member 14. The fixed hook 20 and the movable hook 12 are disposed opposite to each other, and when the pair of clamping jaws 30 of the filling machine relatively move to the clamping position along the clamping direction, the fixed hook 20 and the movable hook 12 can be fastened to each other to maintain the clamped state.

The right-hand filling machine jaw 30 is further provided with a drive member 32 on its clamping side, which can be moved back and forth in the clamping direction, the movable catch 12 being rotatably arranged on the drive member 32. In the embodiment shown in the figures, the movable catch 12 can be connected to the drive element 32 by means of a connecting shaft 126 and can be rotated relative to the drive element 32 about the connecting shaft 126 as a rotational axis when the drive element 32 is moved in the clamping direction. The movable hook 12 is integrally formed and has a hook portion 122 and a movable connecting portion 124, and both the hook portion 122 and the movable connecting portion 124 rotate around the rotation axis along with the movable hook 12.

The fixing member 14 is fixedly arranged on the clamping side of the clamping jaw 30 of the filling machine, and the movable connecting portion 124 of the movable fastening hook 12 can be connected to the fixing member 14. In the process that the driving member 32 reciprocates along the clamping direction relative to the fixing member 14, the moving driving member 32 drives the movable hook 12 to move, and due to the connection relationship between the movable connection portion 124 of the movable hook 12 and the fixing member 14, the movable hook 12 can only rotate with the connection portion of the movable connection portion 124 and the fixing member 14 as a fulcrum and cannot shift, and thus the hook portion 122 of the movable hook 12 is driven to rotate, so that the hook portion 122 can reach the fastening position with the fixed hook 20 and can also be separated from the fastening position. During this process, the movable hook 12 can also be rotated about the connecting shaft 126 under the action of the driving member 32. The rotation axis around which the movable hook 12 rotates about the connection point of the movable connection portion 124 and the fixing member 14 is parallel to the connection axis 126.

The specific working process is shown in fig. 3 to 5. In the embodiment shown in fig. 3 to 5, the movable connection portion 124 of the movable hook 12 has two opposite abutment walls 125, a connection groove is defined between the two opposite abutment walls 125, and the fixing member 14 is an abutment shaft received in the connection groove and contacts the two abutment walls. Depending on the design, the movable connecting portion 124 may also define a connecting slot for receiving the fixing member 14.

As shown in fig. 3, at this time, the two filling jaws 30 have not yet reached their clamping positions, and the hook portion 122 of the movable hook 12 has not yet reached its fastening position, so that the two filling jaws 30 move relatively in the clamping direction X indicated by the arrow in the drawing until reaching the clamping position shown in fig. 4.

At this time, as shown in fig. 4, the driving member 32 is controlled to move to the right in the drawing, i.e. to the right of the filling machine clamping jaw 30 as indicated by the arrow, the driving member 32 pulls the movable hook 12 to move synchronously, and the fixing member 14 abuts against the abutting wall 125 of the movable connecting portion 124 as an abutting shaft, so that the movable hook 12 rotates about the fixing member 14 as a supporting point, and rotates counterclockwise about the connecting shaft 126, so that the hook portion 122 rotates to its fastening position until the fastening action with the fixed hook 20 is completed.

As shown in fig. 5, the hook portion 122 of the movable hook 12 and the fixed hook 20 are fastened to each other, so that the relative position between the pair of clamping jaws 30 of the filling machine is fixed and tensioned, and the subsequent heat sealing process can be completed by the packaging device 40 in this state. If the snap-fit relationship is to be released, the driving member 32 is controlled to move to the left as indicated by the arrow, i.e. toward the left filling machine clamping jaw 30, the driving member 32 pushes the movable hook 12 to move synchronously, and since the fixing member 14 abuts against the abutment wall 125 of the movable connecting portion 124 as an abutment shaft, the movable hook 12 is caused to rotate about the fixing member 14 as a fulcrum and simultaneously rotate clockwise about the connecting shaft 126, so that the hook portion 122 is disengaged from its snap-fit position and returns to the state shown in fig. 4.

The movable buckling hook component is simple in structure, stable and reliable in buckling action, and the elastic piece is replaced by structural cooperation of the fixing piece and the movable connecting part, so that equipment faults caused by damage of the elastic piece are avoided.

In the structure-fitting relationship between the movable connecting portion 124 and the fixing member 14 shown in fig. 3 to 5, the fixing member 14 that abuts against the shaft may be a completely fixed shaft or a rotatable shaft structure. In addition, while the abutment shaft is shown as a cylindrical shaft, those skilled in the art will appreciate that the abutment shaft may be other than cylindrical, such as a hexagonal shaft, depending on the design requirements. In order to reduce sliding friction, rolling elements such as rollers, bearings and the like can also be sleeved on the abutting shaft.

Those skilled in the art will appreciate that other structural engagement relationships may be employed for the articulating portion 124 and the securing member 14, depending upon the design requirements.

Referring to fig. 6, in the embodiment shown in fig. 6, the fixing member 14 has two fixing portions 142 disposed at intervals, and the movable connecting portion 124 can extend between and contact the two fixing portions 142, and the clamping and fastening process is similar to that shown in fig. 3 to 5, and will not be repeated. The two fixing portions 142 are abutting posts, and the abutting posts may be a completely fixed fixing structure or a rotatable shaft structure. In addition, while the abutment shaft is shown as a cylindrical shaft, those skilled in the art will appreciate that the abutment post may be other than cylindrical, such as a hexagonal post, depending on the design requirements. In order to reduce sliding friction, rolling elements such as rollers, bearings and the like can also be sleeved on the abutting columns.

The embodiment shown in fig. 1 and 2 also provides a clamping jaw device of a filling machine, which comprises a pair of filling machine clamping jaws 30 capable of relatively moving along a clamping direction X, wherein a left filling machine clamping jaw 30 is provided with a fixed buckling hook 20 at a clamping side of the filling machine clamping jaws 30, a right filling machine clamping jaw 30 is provided with a driving piece 32 capable of reciprocally moving along the clamping direction at the clamping side of the filling machine clamping jaws, and the movable buckling hook assembly 10, wherein a fixing piece 14 is fixedly arranged at the clamping side of the filling machine clamping jaws, and a movable buckling hook 12 is rotatably arranged on the driving piece 32 around a rotating shaft. In the clamping position of the pair of clamping jaws 30 of the filling machine, when the driving member 32 reciprocates along the clamping direction, the movable hook 12 can be driven to rotate with the connection portion of the movable connecting portion 124 and the fixing member 14 as a fulcrum, so that the hook portion 122 reaches a fastening position with the fixed hook 20 or is separated from the fastening position.

The application also provides a filling machine with the clamping jaw device and a packaging device arranged on the clamping jaw device and used for carrying out heat sealing on packages.

The foregoing is merely a specific embodiment of the application and other modifications and variations can be made by those skilled in the art in light of the above teachings. It is to be understood by persons skilled in the art that the foregoing detailed description is provided for the purpose of illustrating the application more fully, and that the scope of the application is defined by the appended claims.
