Description

Technical Field

[0001] The utility model relates to the technical field of metal can production equipment, in particular to a follow-up clamping stack mechanism. Background Art

[0002] For the convenience of transporting the can lids of pop-top cans, generally, the can lids are arranged in a long strip one by one in sequence, then sealed with a film, and then the sealed long-strip can lid materials are stacked on a tray layer by layer to form a stack (such as the tray and stack shown in Figure 1 ); during processing, it is necessary to fork the tray together with the stack onto the lifting table, and then use a pushing mechanism to push the stack layer by layer from top to bottom onto the conveyor belt.

[0003] When the pushing mechanism pushes the stack, the tray is prone to displacement, affecting the accuracy of the next push. To solve this problem, in the traditional technology, generally two relatively high baffles are arranged on both sides of the stack to clamp both sides of the stack. However, the materials of each layer of some stacks are wound by the same long constraint belt. If the two sides of the stack are still clamped by the baffles, it is very inconvenient to recycle the constraint belt. Under this background, the applicant is committed to researching a follow-up clamping stack mechanism to achieve both clamping and correcting the tray and not affecting the recycling of the constraint belt, thereby making the feeding more convenient. Content of the Utility Model

[0004] The purpose of the utility model is to achieve both clamping and correcting the tray and not affecting the recycling of the constraint belt, thereby making the feeding more convenient.

[0005] In order to achieve the above purpose, the technical solutions adopted by the utility model are as follows:

[0006] A follow-up clamping stack mechanism includes a lifting table and two groups of symmetrically arranged clamping and correcting mechanisms. The lifting table is located between the two groups of clamping and correcting mechanisms. The clamping and correcting mechanism includes a vertical lifting mechanism, a pushing mechanism, and a clamping strip. The vertical lifting mechanism drives the pushing mechanism to vertically move back and forth, and the pushing mechanism drives the clamping strip to move back and forth in the direction towards the other group of clamping and correcting mechanisms.

[0007] Further, the vertical lifting mechanism includes a driving mechanism, a lead screw assembly, a vertical linear guide rail, a slider, and a fixed frame. The driving mechanism drives the lead screw assembly to work, and the lead screw assembly drives the slider to slide up and down along the vertical linear guide rail. The fixed frame is fixedly connected to the slider.

[0008] Further, each group of vertical lifting mechanisms includes two vertical linear guide rails and two sliders. Each slider is correspondingly slidably arranged on one of the groups of vertical linear guide rails, and the fixed frame is fixedly arranged between the two sliders.

[0009] Further, each set of clamping and correcting mechanisms includes two sets of pushing mechanisms and two clamping bars. The two sets of pushing mechanisms are both fixedly arranged on the fixing frame, and each set of pushing mechanisms respectively drives one of the clamping bars to move back and forth in the direction towards the other set of clamping and correcting mechanisms.

[0010] Further, the two clamping bars are arranged side by side with each other.

[0011] Further, the two clamping bars of each set of pushing mechanisms are symmetrically arranged with each other.

[0012] The beneficial effects of the present utility model are as follows: For the correction problem of the tray, the present utility model specifically designs two sets of symmetrically arranged clamping and correcting mechanisms. After the tray carrying the stack of materials is forklifted to the lifting platform, the vertical lifting mechanism drives the pushing mechanism to move vertically. The pushing mechanism drives the clamping bar to extend. Through the double-axis linkage of the vertical lifting mechanism and the pushing mechanism, the clamping bar is driven to extend and abut against the side surface of the tray, so that the clamping bars of the two sets of clamping and correcting mechanisms respectively clamp on both sides of the tray, playing a role in fixing and correcting the tray.

[0013] On the other hand, after the topmost material on the tray is pushed out, the lifting platform drives the tray to rise one grid. At the same time, the vertical lifting mechanism drives the pushing mechanism to rise vertically by one grid, so that the clamping bars continuously clamp on both sides of the tray, and at the same time, it does not affect the feeding operation. Since the clamping bars of the two sets of clamping and correcting mechanisms respectively clamp on both sides of the tray, it does not affect the two sides of the stack of materials, and thus does not affect the recovery of the restraint belt by other mechanisms, making the feeding more convenient.

[0022] The present utility model will be further described below in conjunction with the accompanying drawings.

[0023] As Figures 1 to 3 shown, a follow-up clamping stack mechanism includes a lifting platform 1 and two groups of symmetrically arranged clamping and correcting mechanisms 2. The lifting platform 1 is located between the two groups of clamping and correcting mechanisms 2.

[0024] The clamping and correcting mechanism 2 includes a vertical lifting mechanism 21, a pushing mechanism 22 and a clamping strip 23. The vertical lifting mechanism 21 drives the pushing mechanism 22 to vertically move back and forth, and the pushing mechanism 22 drives the clamping strip 23 to move back and forth in the direction towards the other group of clamping and correcting mechanisms 2.

[0025] The vertical lifting mechanism 21 includes a driving mechanism (not shown in the drawings), a lead screw assembly (not shown in the drawings), a vertical linear guide 211, a slider 212 and a fixing frame 213. The driving mechanism drives the lead screw assembly to work, and the lead screw assembly drives the slider 212 to slide up and down along the vertical linear guide 211. The fixing frame 213 is fixedly connected to the slider 212.

[0026] Each group of vertical lifting mechanisms 21 includes two vertical linear guides 211 and two sliders 212. Each group of sliders 212 is slidably arranged on one of the groups of vertical linear guides 211. The fixing frame 213 is fixedly arranged between the two groups of sliders 212. When the driving mechanism drives the lead screw assembly to work and the lead screw assembly drives the slider 212 to slide up and down along the vertical linear guide 211, the slider 212 also drives the fixing frame 213 to move up and down. In this embodiment, the design of the two groups of sliders 212 enables the fixing frame 213 to maintain stability during movement.

[0027] Each group of clamping and correcting mechanisms 2 includes two pushing mechanisms 22 and two clamping strips 23. The two groups of pushing mechanisms 22 are both fixedly arranged on the fixing frame 213. Each group of pushing mechanisms 22 respectively drives one of the clamping strips 23 to move back and forth in the direction towards the other group of clamping and correcting mechanisms 2. After the tray 3 carries the stack 4 and is forklifted onto the lifting platform 1, the vertical lifting mechanism 21 drives the pushing mechanism 22 to move vertically, and the pushing mechanism 22 drives the clamping strip 23 to extend. Through the double-axis linkage of the vertical lifting mechanism 21 and the pushing mechanism 22, the clamping strip 23 is driven to extend and abut against the side surface of the tray 3, so that the clamping strips 23 of the two groups of clamping and correcting mechanisms 2 respectively clamp on both sides of the tray 3, playing a role in fixing and correcting the tray 3.

[0028] The two clamping strips 23 are arranged side by side, and the two clamping strips 23 of each group of pushing mechanisms 22 are symmetrically arranged. The design of the two clamping strips 23 makes the thrust received by the side of the tray 3 more uniform, and the situation where the front half is stressed and the rear half is not stressed will not occur.

[0029] The working principle of the present utility model is as follows: After the pallet 3 carrying the material stack 4 is forklifted onto the lifting platform 1, the driving mechanism drives the lead screw assembly to work. The lead screw assembly drives the slider 212 to slide along the vertical linear guide 211, and the pushing mechanism 22 drives the clamping strip 23 to extend. Through the dual-axis linkage of the vertical lifting mechanism 21 and the pushing mechanism 22, the clamping strip 23 is driven to extend and abut against the side of the pallet 3, so that the clamping strips 23 of the two groups of clamping and correcting mechanisms 2 are respectively clamped on both sides of the pallet 3, playing a role in fixing and correcting the pallet 3.

[0030] After the topmost layer of materials on the pallet 3 is pushed out, the lifting platform 1 drives the pallet 3 to rise one grid. At the same time, the vertical lifting mechanism 21 drives the pushing mechanism 22 to rise vertically one grid, so that the clamping strips 23 continue to be clamped on both sides of the pallet 3, and at the same time, it does not affect the feeding operation. Since the clamping strips 23 of the two groups of clamping and correcting mechanisms 2 are respectively clamped on both sides of the pallet 3, it does not affect both sides of the material stack 4, so it will not affect the recovery of the restraint belt 5 by other mechanisms, making the feeding more convenient.

Therefore, equivalent changes made according to the scope of the patent application of the present utility model still fall within the scope covered by the present utility model. The above does not impose any limitation on the technical scope of the present utility model. Any modification, equivalent change and modification made to the above embodiments based on the technical essence of the present utility model still fall within the scope of the technical solution of the present utility model.
