DETAILED DESCRIPTION

[0021] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the utility model.

[0022] Please refer to Figures 1-5 The utility model provides a kind of technical scheme: a packaging bag stacking device, including stand 1, conveying belt 6, plug-in platform 601 is fixedly connected in the back of conveying belt 6, avoiding groove 602 is opened in plug-in platform 601, limiting sliding groove 102 is symmetrically opened in the front of stand 1, bracket 4 is arranged in the front of stand 1, limiting sliding block 401 is symmetrically fixedly connected in the back of bracket 4, limiting sliding block 401 and limiting sliding groove 102 are slidingly matched, bearing plate 5 is placed on bracket 4, roller 503 is fixedly connected in the position of being close to the corner edge of bearing plate 5 lower surface, first cylinder 2 is fixedly connected in the back of stand 1, clamping mechanism 3 is fixedly connected in the output end of first cylinder 2, clamping mechanism 3 includes mounting seat 301, first clamping block 302, second clamping block 306, first clamping block 302 is fixedly connected in the front of mounting seat 301.

[0023] In this embodiment, by utilizing the cooperation of the first clamping block 302 and the second clamping block 306, the packaging bag can be clamped and fixed. The first clamping block 302 can be inserted into the clearance groove 602, so that the clamping mechanism 3 is located in the insertion platform 601. The packaging bag is transported by the conveyor belt 6 and is conveyed to the top of the insertion platform 601. The first clamping block 302 is stuck in the clearance groove 602 and is located below the packaging bag. The second clamping block 306 is located above the packaging bag. Then, the second clamping block 306 is moved down to clamp the rear end of the packaging bag. The first cylinder 2 is activated to drive the clamping mechanism 3 to move backward, and the clamping mechanism 3 pulls the packaging bag above the carrier plate 5. After the bag is completely above the support plate 5, the second clamping block 306 moves up to release the bag. Then, the first cylinder 2 is activated to move the clamping mechanism 3 backward, separating the clamping mechanism 3 from the bag. At this time, the bag will fall above the support plate 5. Repeating the above operation can achieve the stacking of the bags. As the thickness of the stacked bags increases, the bracket 4 needs to be controlled to move the support plate 5 down synchronously to prevent the top of the stacked bags from being higher than the conveyor belt 6. After stacking is completed, the bracket 4 is controlled to move down to the bottom. At this time, the roller 503 under the support plate 5 will contact the ground, and the stacked bags can be directly pushed and transported without manual handling.

[0024] To achieve the purpose of adjusting the height of the support plate 5, the device adopts the following technical solution: A base 101 is fixedly connected to the bottom of the support frame 1, and a threaded rod 103 is rotatably installed in one of the limiting slide grooves 102. A drive motor 104 is fixedly connected to the top of the support frame 1, and the output end of the drive motor 104 is fixedly connected to the threaded rod 103. A threaded sleeve block 402 is embedded in one of the limiting sliders 401, and the threaded sleeve block 402 is threadedly engaged with the threaded rod 103. A limiting protrusion 403 is fixedly connected to the top of the bracket 4. A snap-fit ​​groove 501 is opened on the bottom of the support plate 5, and a limiting hole 502 is opened in the snap-fit ​​groove 501. The roller 503 cooperates with the limiting protrusion 403.

[0025] By starting the drive motor 104, the threaded rod 103 can be rotated. The threaded rod 103 is threadedly engaged with the threaded sleeve block 402. The rotation of the threaded rod 103 can drive the limit slider 401 to move. The movement of the limit slider 401 can drive the bracket 4 to move. The movement of the bracket 4 will drive the support plate 5 to move, thereby adjusting the height of the support plate 5. The roller 503 and the limit protrusion 403 cooperate with each other to lock the support plate 5 onto the bracket 4, avoiding the problem of the support plate 5 sliding and misaligning.

[0026] Wherein, in order to realize the purpose of clamping and fixing the packaging bag, the device adopts the following technical scheme: the rear of the mounting seat 301 is fixedly connected with the connecting seat 304, the rear of the connecting seat 304 is fixedly connected with the first cylinder 2, the connecting sliding groove 303 is arranged in the mounting seat 301, the rear of the second clamping block 306 is fixedly connected with the connecting sliding block 307, the connecting sliding block 307 is in sliding fit with the connecting sliding groove 303, the upper surface of the mounting seat 301 is fixedly connected with the second cylinder 305, the output end of the second cylinder 305 is fixedly connected with the connecting sliding block 307, and the upper surface of the bearing plate 5 is fixedly connected with the limiting vertical plate 504.

[0027] By starting the second cylinder 305, the connecting sliding block 307 can be driven to move, the connecting sliding block 307 moves, and the second clamping block 306 is driven to move, so that the distance between the second clamping block 306 and the first clamping block 302 is adjusted, the packaging bag is clamped by the second clamping block 306 and the first clamping block 302, and the limiting vertical plate 504 is located at the position of the rear side of the bearing plate 5.

[0028] The working principle and use process of the utility model: when using, the packaging bag needs to be transmitted by the transmission belt 6, the packaging bag is conveyed to the plug-in platform 601, then the clamping mechanism 3 clamps one end of the packaging bag, the first cylinder 2 is started to drive the clamping mechanism 3 to move backward, the clamping mechanism 3 drives the clamped packaging bag to move backward, the packaging bag is dragged to the upper surface of the bearing plate 5, when the packaging bag is completely located above the bearing plate 5, the second cylinder 305 is started to drive the second clamping block 306 to move upward, so that the clamping of the packaging bag is released, the first cylinder 2 is continuously started to drive the clamping mechanism 3 to move backward, so that the clamping mechanism 3 is separated from the packaging bag, at this time, the packaging bag falls above the bearing plate 5, the above operation is repeated, the packaging bag can be stacked, after stacking, the bracket 4 is controlled to move downward to the lowermost position, at this time, the rollers 503 below the bearing plate 5 can contact the ground, so that the bearing plate 5 can be directly pushed to drive the stacked packaging bag to the next process.
