Abstract
Description
Technical Field
[0001] This utility model relates to the field of mechanical technology, specifically to a plastic bag cutting, stacking, and alignment mechanism. Background Technology
[0002] Chinese Patent Document CN219190397U discloses a cutting mechanism with a compaction function, which achieves the effect of cutting double-layer plastic films with consistent dimensions. The cutting mechanism includes a processing table with a through groove in which a conveyor roller is rotatably mounted. A drive motor for driving the conveyor roller is bolted to the outside of the processing table. A pressure roller is positioned directly above the conveyor roller. Two sliders symmetrically distributed on the outside of the pressure roller are rotatably connected to the pressure roller. The entire assembly of the sliders and pressure rollers is connected to the processing table via a mounting frame, which is fixedly connected to the processing table. The sliders are slidably connected to the mounting frame. This invention allows for longitudinal position adjustment and compaction of the double-layer plastic film before cutting, ensuring that the double-layer plastic film remains aligned and relatively stationary during cutting, effectively improving the synchronous cutting accuracy of the double-layer plastic film.
[0003] However, in the above solutions and existing technologies, the sizes of plastic bags vary in actual production. Different customers and different uses have different needs for the size of plastic bags. However, most of the existing stacking and alignment mechanisms adopt a fixed size design and cannot change the adaptable components according to the size of the plastic bags. Therefore, optimization and improvement can be carried out.
[0004] Therefore, this utility model proposes a plastic bag cutting, stacking and alignment mechanism to solve the above problems. Utility Model Content

[0007] A cutting blade is fixedly installed on the top of the workbench, and a roller is fixedly installed on the side end of the workbench;
[0008] A sliding component is fixed to one end of the workbench, a clamping component is fixed to the sliding component, and an auxiliary component is provided on the clamping component.
[0009] Preferably, the forward and reverse motor in the sliding assembly is fixedly installed at one end of the positioning plate, and a first rotating shaft is fixedly installed at one end of the forward and reverse motor, with a belt sleeved on the first rotating shaft.
[0010] Preferably, a second rotating shaft is sleeved on the other side of the belt in the sliding assembly, and symmetrical lead screws are fixedly installed on the second rotating shaft.

[0012] Preferably, the first alignment plate in the auxiliary component has a first groove at its end, and the first protrusion is engaged in the first groove.
[0013] Preferably, the second alignment plate in the auxiliary component has a second protrusion at its end, the second protrusion being adapted to engage with a second groove, and the second groove being disposed at the end of the first alignment plate.
[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: By setting up a structure including a worktable, a cutting blade, rollers, a sliding assembly, a clamping assembly, and auxiliary components, and utilizing the forward and reverse motor, the first rotating shaft, the belt, the second rotating shaft, and the symmetrical lead screw in the sliding assembly, the clamping assembly can be precisely driven to move.

[0020] The technical solutions in the embodiments of this utility model will be clearly and completely described below. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.
[0021] Example 1: Please refer to Figures 1-2 A plastic bag cutting, stacking and alignment mechanism includes a workbench 1, a cutting blade 2, a roller 3, a sliding component 4, a clamping component 5, and an auxiliary component 6. The cutting blade 2 is fixedly installed on the top of the workbench 1, and the roller 3 is fixedly installed on the side end of the workbench 1. The sliding component 4 is fixedly installed on one side end of the workbench 1, the clamping component 5 is fixedly installed on the sliding component 4, and the auxiliary component 6 is installed on the clamping component 5.
[0022] The forward and reverse motor 401 in the sliding assembly 4 is fixedly installed on one side of the positioning plate 402. A first rotating shaft 403 is fixedly installed on one side of the forward and reverse motor 401, and a belt 404 is sleeved on the first rotating shaft 403.
[0023] In use, the raw plastic bag to be cut is first introduced above the workbench 1 through the roller 3. The roller 3 plays a role in stable conveying and ensures that the plastic bag moves forward smoothly. At this time, the forward and reverse motor 401 is in standby mode. The positioning plate 402 provides stable support for the forward and reverse motor 401 to ensure that the motor will not be displaced when it is running. The first rotating shaft 403 is tightly connected to the forward and reverse motor 401. After the motor starts, the power is transmitted through the first rotating shaft 403 to the sleeved belt 404. The belt 404 serves as a transmission component and is ready to drive the subsequent components to operate.
[0024] Example 2: Based on Example 1, please refer to... Figures 2-3 The other side of the belt 404 in the sliding assembly 4 is sleeved with a second rotating shaft 405, and a symmetrical lead screw 406 is fixedly installed on the second rotating shaft 405.
[0025] The clamping plate 501 in the clamping assembly 5 is fixedly provided with a sliding ring 502 at its end. The sliding ring 502 is appropriately connected to the symmetrical lead screw 406. The clamping plate 501 is provided with a first protrusion 503 at its end.
[0026] In use, as the belt 404 rotates, power is transmitted to the second rotating shaft 405, driving the symmetrical lead screw 406 fixed thereon to rotate synchronously. Since the sliding ring 502 at the end of the clamping plate 501 is sleeved on the symmetrical lead screw 406, the rotational motion of the lead screw is converted into the linear movement of the clamping plate 501. By controlling the direction of the forward and reverse motor 401, the clamping plate 501 can move towards or away from each other to accommodate plastic bags of different widths. For example, when facing a wider plastic bag, the motor is started to move the lead screw to move the clamping plate 501 outward, increasing the clamping distance; conversely, for a narrower plastic bag, the clamping plate 501 moves inward. At this time, the first protrusion 503 at the end of the clamping plate 501 also moves with the clamping plate 501, preparing for subsequent connection with the auxiliary component 6.
[0027] Example 3: Based on Example 2, please refer to... Figures 3-4 The first alignment plate 601 in the auxiliary component 6 has a first groove 602 at its end, and the first protrusion 503 is engaged in the first groove 602.
[0028] The second alignment plate 603 in the auxiliary component 6 is provided with a second protrusion 604 at its end. The second protrusion 604 is adapted to be snapped into the second groove 605, which is located at the end of the first alignment plate 601.
[0029] In use, after the clamping plate 501 is moved into place, the auxiliary component 6 is installed in place, so that the first groove 602 at the end of the first alignment plate 601 is accurately engaged with the first protrusion 503 at the end of the clamping plate 501, achieving a tight connection between the two. This ensures that the auxiliary component 6 can move synchronously with the position adjustment of the clamping plate 501. Then, the second protrusion 604 at the end of the second alignment plate 603 is engaged into the second groove 605 at the end of the first alignment plate 601, further stabilizing the structure of the auxiliary component 6. At this time, the entire auxiliary component 6 works in concert with the clamping component 5. For plastic bags of different sizes, it can be accurately aligned from multiple directions, ensuring that the cutting position of the plastic bag is accurate when the cutting blade 2 performs the cutting operation. This improves the accuracy of cutting and stacking alignment, reduces the time spent on subsequent manual adjustments, and improves overall production efficiency.
