Description

Technical Field

[0001] The utility model belongs to the technical field of sewing equipment and relates to a linkage device and a bag opening machine. Background Art

[0002] In the process of clothing production, pockets often need to be sewn. During the processing of pockets, the pocket fabric needs to be cut first, and then the folding mechanism folds the pocket fabric, and then the folding mechanism moves to the sewing mechanism for sewing. Regarding the processing steps of pockets, reference can be made to a processing technology for a bag opening machine and bag mouth sewing provided by application number 202410277290.8.

[0003] The prior art has the following shortcomings: the folding mechanism needs to fold the material on the left side of the mounting frame, and then move the folding mechanism to the sewing mechanism on the right side of the mounting frame for sewing, resulting in the sewing area on the right side being idle for a long time during the folding process, wasting working time. Summary of the invention

[0004] The utility model aims at the above problems existing in the prior art and provides a linkage device. The technical problem to be solved by the utility model is: how to improve the working efficiency.

[0005] The purpose of the utility model can be achieved through the following technical solutions:

[0006] A linkage device comprises a mounting frame, on which a movable mounting seat 1 and a movable mounting seat 2 are arranged, on which a sewing mechanism is arranged, and on which a material folding mechanism is arranged, and wherein the linkage device further comprises a connecting mechanism for connecting or disconnecting the mounting seat 1 and the mounting seat 2.

[0007] Its working principle is: in the initial state, the material folding mechanism moves to the top of the sewing mechanism, and the mounting seat 1 and the mounting seat 2 are abutted against each other, and then the connecting mechanism connects the mounting seat 1 and the mounting seat 2, and the movement of the mounting seat 1 drives the movement of the mounting seat 2. During the movement, the material folding mechanism performs the material folding action, and when the mounting seat 1 and the mounting seat 2 move to the material picking point together, the material folding mechanism on the mounting seat 2 also completes the material folding action.

[0008] Then the connecting mechanism separates the mounting seat 1 and the mounting seat 2, the folding mechanism does not move and remains at the material taking position, the mounting seat 1 drives the sewing mechanism to move quickly to the sewing area, and the sewing mechanism sews the pocket fabric.

[0009] In the linkage device, the connecting mechanism connects the material folding mechanism and the sewing mechanism together, and the material folding mechanism and the sewing mechanism can be linked. In the initial state, the material folding mechanism can be moved above the sewing mechanism. In the process of the material folding mechanism and the sewing mechanism moving together for subsequent material retrieval (such as zipper retrieval), the material folding mechanism can fold the pocket fabric, and there is no need to wait for the material folding mechanism to complete folding before the sewing mechanism moves for subsequent material retrieval, which saves the waiting time when folding materials and improves work efficiency.

[0010] In the above-mentioned linkage device, the connecting mechanism includes a connecting block, a connecting pin and a driving member for driving the connecting pin to move, the connecting block is installed on a mounting seat, a socket is provided on the connecting block, the driving member is installed on a mounting seat, and the connecting pin can be inserted into or withdrawn from the socket.

[0011] When the driving member 1 drives the connecting pin to extend and plug into the socket of the connecting block, the mounting seat 1 and the mounting seat 2 are connected together and the two can be linked. When the driving member 1 drives the connecting pin to withdraw, the mounting seat 1 and the mounting seat 2 are separated and the two can move separately.

[0012] In the above-mentioned linkage device, the driving member 1 includes a cylinder 1, and the cylinder 1 is mounted on a mounting seat 2, and the connecting pin is mounted on the piston rod of the cylinder 1.

[0013] As other embodiments, cylinder 1 may also be replaced by an oil cylinder, a linear motor, an electromagnet, or a motor plus a screw drive.

[0014] In the above-mentioned linkage device, it also includes a driving member 2 for driving the second mounting seat to move, and the driving member 2 includes a cylinder 2. The cylinder 2 is installed on the mounting frame, and the piston rod of the cylinder 2 is connected to the second mounting seat.

[0015] Cylinder 2 is used to drive mounting seat 2 to move toward mounting seat 1, so that the folding mechanism moves to the sewing mechanism. After folding and sewing are completed, mounting seat 1 and mounting seat 2 are separated, and cylinder 2 drives mounting seat 2 to move in the opposite direction to reset the folding mechanism.

[0016] If it is a pocket sewn once, after sewing is completed, the cloth folding mechanism returns to its initial state through the pulling force of cylinder two; if it is a pocket sewn twice, the folding mechanism and the sewing mechanism are linked, and after the sewing mechanism moves to the left side of the mounting frame to pick up the material for the second time, the sewing mechanism quickly moves to the sewing area for the second sewing. After sewing is completed, the mounting seat returns to the origin, and at this time the cloth folding mechanism returns to its initial state through the pulling force of cylinder two.

[0017] As other embodiments, cylinder 2 may also be replaced by an oil cylinder or a linear motor or a motor plus a belt drive or a motor plus a screw drive.

[0018] In the above-mentioned linkage device, a guide rail is installed on the mounting frame, a slider is installed on the second mounting seat, and the slider is slidably connected to the guide rail.

[0019] The guide rail and the slider form a sliding guide structure, which can improve the stability of the installation when moving.

[0020] In the above-mentioned linkage device, it also includes a driving component three for driving the mounting seat one to move, the driving component three includes a motor, a synchronous wheel is installed on the output shaft of the motor, another synchronous wheel is installed on the mounting frame, a synchronous belt is connected between the two synchronous wheels, and the mounting seat one is fixed on the synchronous belt.

[0021] Driven by the motor, the synchronous wheel drives the synchronous belt to rotate, and the synchronous belt drives the installation to move.

[0022] The utility model also provides a bag opening machine, which comprises any one of the above linkage devices.

[0023] Compared with the prior art, the advantages of the utility model are as follows:

[0024] The folding mechanism and the sewing mechanism of the linkage device can be linked together. When the folding mechanism and the sewing mechanism move together, the folding mechanism can fold the pocket fabric, which can shorten the waiting time for folding the material and improve work efficiency.

During the movement, the material folding mechanism 5 performs the material folding action. When the mounting seat 1 2 and the mounting seat 2 3 move to the material picking point together, the material folding mechanism 5 on the mounting seat 2 3 also completes the material folding action.

[0033] Afterwards, the connecting mechanism 6 separates the mounting seat 1 2 and the mounting seat 2 3, the folding mechanism 5 does not move and remains in the material taking position, and the mounting seat 1 2 drives the sewing mechanism 4 to move quickly to the sewing area, and the sewing mechanism 4 sews the pocket fabric.
