[0010] Compared with the prior art, the beneficial effects of the present invention are: the handbag clamping device has the following advantages:

[0011] 1. The present invention is provided with a connecting assembly. When the clamping device moves to the bag clamping station, the inclined surface of the positioning plate in the external station positioning device rotates with the bearing on the support shaft, so that the external station positioning device moves the support shaft to the left during the downward movement. At the same time, due to the fixed connection between the connecting block 2 and the support plate, the support shaft compresses the compression spring to drive the connecting shaft 2 to move to the left, and then drives the entire mechanism to move to the left, so that each station is positioned based on the support shaft, thereby ensuring the accuracy of the working position of each station.

The main rocker arm and the rocker arm cooperate with each other through the pin shaft, so that the external driving mechanism drives the rocker arm and the main rocker arm to rotate synchronously, thereby realizing the clamping action of the clamping jaws. When the main rocker arm drives the rocker arm to rotate counterclockwise, the connecting block drives the clamping jaws to move outward along the guide shaft, thereby realizing the bag loosening action of the clamping jaws. When the main rocker arm drives the rocker arm to rotate clockwise, the clamping jaws realize the clamping action. At the same time, through the characteristics of the tension spring, the stability of the two required working states can be maintained, which ensures the characteristics of fast, efficient and trouble-free clamping operation.

[0013] The device utilizes the long strip mounting holes on each component to realize left and right movement of the device to adapt to the operation requirements of different hole spacings. It is convenient and quick. The invention is cleverly designed to avoid manual operation, which not only saves labor costs, but also improves work efficiency and accuracy, which is beneficial to the development of the packaging equipment industry.

The relative distance between the horizontal back plates 4 can be adjusted by bolts, so as to be suitable for the clamping of handbags of various specifications, and increase the use range of the device. When the clamping device moves to the clamping position, the external driving device contacts the raised pin shaft on the main swing rod 10 and drives it to move back and forth, and the external driving device is matched with the pin shaft between the main swing rod 10 and the swing rod 9, so that the external The driving mechanism drives the swing rod 9 and the main swing rod 10 to rotate synchronously clockwise or counterclockwise, so as to realize the clamping and bag releasing action of the clamping jaw 5. When the main swing rod 10 drives the swing rod 9 to rotate counterclockwise, the connecting block 1 6 drives the clamping jaw 5 to move outward along the guide shaft 7, so as to realize the bag releasing action of the clamping jaw 5. When the main swing rod 10 drives the swing rod 9 to rotate clockwise, the clamping jaw 5 realizes the clamping action. At the same time, through the characteristics of the tension spring 8, the two required stable working states can be maintained, which ensures the advantages of fast, efficient and trouble-free clamping operation. The connecting component 2 includes a connecting shaft 21, both ends of the connecting shaft 21 pass through the connecting block 22 and are connected to the two groups of support plates 1, and a support shaft 2 is provided on the right side of the connecting shaft 21. 3. A bearing is provided in the middle of the support shaft 23, and both ends of the support shaft 23 are connected to the slider 25 through a compression spring 24. A slide groove is provided in the connecting block 2, and the compression spring and the slider are both located in the slide groove of the connecting block 2. When the clamping device moves to the bag clamping station, the inclined surface of the positioning plate in the external station positioning device rotates with the bearing on the support shaft 23, so that the external station positioning device moves the support shaft 23 to the left during the movement. At the same time, due to the fixed connection between the connecting block 22 and the support plate 1, the support shaft 23 compresses the compression spring 24 to drive the connecting shaft 21 to move to the left, thereby driving the entire mechanism to move to the left, so that each station is positioned based on the support shaft 23, thereby ensuring the accuracy of the working position of each station.

The backrest 11 is connected to the inner wall of the two groups of support plates 1 through a connecting plate. The connecting block 6 and the clamping claw 5 move along the guide shaft 7. When the swing rod 9 rotates clockwise to the backrest 11, it stops rotating, that is, when the connecting block 6 and the clamping claw 5 move inward along the guide shaft 7, the clamping action of the clamping claw 5 is realized. A U-shaped groove is provided in the middle of the back plate 4, and the two sides of the U-shaped groove of the back plate 4 are connected to the two groups of clamping plates 12 through pins. The upper ends of the two groups of clamping plates 12 are connected by connecting springs 13, and the spacing between the two groups of clamping plates 12 is the same as the U-shaped groove on the back plate 4.

[0020] During use: the clamping device is in an open and closed state when the handbag is not clamped for transmission. When the clamping device moves to the bag clamping station, first, the support shaft 23 is moved to the left through the external station positioning device, and the support shaft 23 compresses the compression spring 24 to drive the connecting shaft 21 to move to the left, thereby driving the entire mechanism to move to the left, so that each station is positioned based on the support shaft 23, thereby ensuring the accuracy of the working position of each station, and then the external driving device contacts the raised pin shaft at one end of the main swing rod 10 and moves it.
