Description

Technical Field

[0001] This utility model relates to the field of finished plastic woven bag packaging technology, and in particular to a finished plastic woven bag packaging equipment with a rapid extrusion function. Background Technology

[0002] Plastic woven bags are classified by their main material composition as polypropylene bags and polyethylene bags, and by their sewing method as sewn bottom bags and sewn side bottom bags. Common types of plastic woven bags include: feed woven bags, chemical woven bags, putty powder woven bags, urea woven bags, vegetable mesh bags, and fruit mesh bags. During the production process of plastic woven bags, professional packaging equipment is essential for convenient transportation.

[0003] A search of Chinese utility model patent (publication number CN216943905U) reveals a packaging device for finished plastic woven bags, including a mounting plate, a groove, a sliding strip, an adjusting bolt, a concave connecting plate, a first hydraulic cylinder, a first pressure plate, a second hydraulic cylinder, and a second pressure plate. This device facilitates adjustment of the placement length and allows for the compression packaging of woven bags of different lengths.

[0004] However, practical application has revealed that this technical solution still has at least the following drawbacks:

[0005] This technical solution requires workers to pack the compressed woven bags. Manual packing is relatively slow, especially in large-scale production, making it difficult to meet the demands of efficient production. Furthermore, different workers may use varying standards and pressure when packing, resulting in inconsistent packing quality. Some woven bags may be packed too loosely, making them prone to unraveling during transportation and storage; others may be packed too tightly, easily damaging the bags. Utility Model Content

[0006] The present invention aims to provide a packaging equipment for finished plastic woven bags with a rapid extrusion function to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A packaging device for finished plastic woven bags with rapid extrusion function includes a device body and a packing frame. The device body is connected to a first hydraulic rod, and the telescopic end of the first hydraulic rod is connected to a main pressure plate. The main pressure plate has an installation groove, and the inner wall of the installation groove is connected to a first magnetic strip. The packing frame is connected to a second magnetic strip, and the second magnetic strip attracts the first magnetic strip. The device body has a first sliding groove, and the inner wall of the first sliding groove is slidably connected to a sealing rod. The sealing rod is connected to an insert block, and the insert block has a hidden groove. The inner wall of the hidden groove is connected to a first spring, and the other end of the first spring is connected to a locking block. The locking block is slidably connected to the hidden groove. The packing frame has a slot, and the inner wall of the slot has a locking groove. The locking groove cooperates with the locking block, and the slot cooperates with the insert block. The device body is connected to a second hydraulic rod, and the telescopic end of the second hydraulic rod is connected to a push plate.

[0009] Preferably, the device body has a second slide groove and a third slide groove, and a first slide plate and a second slide plate are slidably connected to the inner walls of the second slide groove and the third slide groove, respectively. The first slide plate and the second slide plate are connected to an extension box, and the extension box is connected to a third hydraulic rod. The telescopic end of the third hydraulic rod is connected to an auxiliary pressure plate.

[0010] Preferably, the device body is slidably connected to a pin, the pin is connected to a handle, the first slide plate has a socket, the socket cooperates with the pin, and a second spring is sleeved on the outside of the pin, with the two ends of the second spring connected to the handle and the device body respectively.

[0011] Preferably, the packing frame is slidably connected to a top post, the top post is connected to a button, and a third spring is sleeved on the outside of the top post, with both ends of the third spring connected to the button and the packing frame, respectively.

[0012] Preferably, the device body is connected to a placement plate.

[0013] The beneficial effects of this technical solution compared to existing technologies are as follows:

[0014] (1) This technical solution, by setting up a packing frame and sealing rod, can pack the woven bags simultaneously with the main pressure plate squeezing them, ensuring uniform and standardized packing. This avoids the possibility of packing too loosely or too tightly, which may occur during manual packing, thus improving the packaging quality of the products. It also reduces the workload and intensity of the workers. By setting up inserts, locking blocks, slots, grooves, and a first spring, the first spring can provide continuous elastic force to push the locking blocks into the grooves, ensuring that the packing frame and sealing rod are firmly connected together, preventing the packing frame from separating from the sealing rod and causing the packed woven bags to scatter.

[0015] (2) By setting the first and second sliding plates, the position of the extension box can be adjusted, thereby adjusting the length of the woven bag placement position, facilitating the compression packaging of woven bags of different lengths. By setting the pin, the second spring, and the insertion hole, the position of the first sliding plate can be restricted, thereby restricting the position of the extension box and preventing it from moving freely. The second spring can provide continuous elasticity, ensuring that the pin is always subjected to an outward pushing force after being inserted into the insertion hole, thereby ensuring a tight fit between the pin and the insertion hole, preventing loosening and falling off, and maintaining the stability of the connection.

[0016] (3) By setting a top post, a third spring, and a button, the locking block can be pushed out of the slot, thereby separating the packing frame from the sealing rod. This allows the packing frame to be quickly removed from the woven bag, facilitating subsequent use of the woven bag. Furthermore, the disassembled packing frame and sealing rod can be reused to pack the woven bag again. The third spring allows the top post to return to its original position after being pressed, facilitating the next press.

[0017] (4) By setting up push plates and placement plates, the packaged woven bags can be moved from the equipment to the placement plates, making it easier for staff to transfer the packaged woven bags. Attached Figure Description

[0023] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments:

[0024] like Figure 1-4The illustrated packaging equipment for finished plastic woven bags with rapid extrusion function includes a main body 1 and a packing frame 7. A first hydraulic rod 2 is connected to the top wall of the main body 1, passing through the top wall of the main body 1. The telescopic end of the first hydraulic rod 2 is connected to a main pressure plate 3. The bottom wall of the main pressure plate 3 has several mounting grooves 15, and the inner wall of the mounting grooves 15 is connected to a first magnetic strip 5. The top wall of the packing frame 7 is connected to a second magnetic strip 6, which attracts the first magnetic strip 5. The magnetic force between the first magnetic strip 5 and the second magnetic strip 6 is greater than the weight of the packing frame 7, allowing the packing frame 7 to move with the main pressure plate 3 under the action of the magnetic force. The inner top wall of the packing frame 7 is flush with the lower surface of the pressure plate. The bottom wall of the main body 1 has several first sliding grooves 12, which are aligned with the mounting grooves 15. A sealing rod 10 is slidably connected to the inner wall of the first sliding groove 12, and the upper surface of the sealing rod 10 is flush with the bottom wall of the main body 1.

[0025] like Figure 3 As shown, the sealing rod 10 has insert blocks 28 connected to the front and rear sides of its upper surface. A hidden groove 21 is provided on one side of the insert block 28, and a first spring 22 is connected to the inner wall of the hidden groove 21. A locking block 23 is connected to the other end of the first spring 22. The locking block 23 is trapezoidal, with its inclined surface facing upwards and its flat surface facing downwards. The locking block 23 is slidably connected to the hidden groove 21. The packing frame 7 has a slot 20, and a slot 24 is provided on the inner wall of the slot 20. The slot 24 engages with the locking block 23, and the slot 20 engages with the insert block 28. A top post 27 is slidably connected to the packing frame 7. One end of the top post 27 is located inside the packing frame 7 and flush with the slot 24. A button 26 is connected to the other end of the top post 27. A third spring 25 is sleeved on the outside of the top post 27, and both ends of the third spring 25 are connected to the button 26 and the packing frame 7, respectively. When the first hydraulic rod 2 extends and pushes down the main pressure plate 3, the packing frame 7 moves down accordingly. The insert block 28 is inserted into the slot 20. The inner wall of the slot 20 presses against the retaining block 23 along its inclined surface, compressing the first spring 22. The retaining block 23 is hidden in the hidden groove 21. When the packing frame 7 continues to move down and the retaining block 23 aligns with the slot 24, the spring rebounds and presses against the retaining block 23, causing it to engage in the slot 24. The packing frame 7 is restricted by the downward plane of the retaining block 23 and cannot separate from the insert block 28, thus ensuring a secure connection between the packing frame 7 and the sealing rod 10. The compressed woven bag is then directly packed. At this time, the first hydraulic rod 2 retracts, causing the main pressure plate 3 to move up. The magnetic force between the first magnetic strip 5 and the second magnetic strip 6 is less than the combined weight of the packing frame 7, the woven bag, and the sealing rod 10. Therefore, the first magnetic strip 5 separates from the second magnetic strip 6, leaving the packing frame 7 at the bottom. Press button 26 to compress the third spring 25, causing the top post 27 to be located inside the packing frame 7 and press the locking block 23, which in turn compresses the first spring 22. The locking block 23 is then pressed into the hidden groove 21. Lift the packing frame 7 upwards, causing the inner wall of the slot 20 to press the locking block 23 again. At this point, button 26 can be released, and the third spring 25 will rebound and push the top post 27 back to its original position. Continue to lift the packing frame 7 upwards to detach the packing frame 7 from the sealing rod 10.

[0026] like Figure 1-2 As shown, a second hydraulic rod 19 is connected to the rear wall of the equipment body 1. The second hydraulic rod 19 passes through the rear wall of the equipment body 1, and a push plate 8 is connected to the telescopic end of the second hydraulic rod 19. A placement plate 11 is connected to the front side of the bottom wall of the equipment body 1, and the placement plate 11 is flush with the upper surface of the bottom wall of the equipment body 1. When the second hydraulic rod 19 extends, it pushes the stuck packing frame 7 forward. The packing frame 7 drives the sealing rod 10 to slide forward along the first slide groove 12 until it is completely disengaged from the first slide groove 12. At this time, the packing frame 7, the sealing rod 10, and the packed woven bag are moved together onto the placement plate 11.

[0027] like Figure 1 As shown, the top wall of the equipment body 1 has second sliding grooves 4 on both sides, and the bottom wall of the equipment body 1 has third sliding grooves 9 on both sides. The inner walls of the second sliding grooves 4 and the third sliding grooves 9 are respectively slidably connected to a first sliding plate 18 and a second sliding plate 13. The first sliding plate 18 and the second sliding plate 13 are connected together to an extension box 14. The top wall of the extension box 14 is connected to a third hydraulic rod 17, which passes through the top wall of the extension box 14. The telescopic end of the third hydraulic rod 17 is connected to an auxiliary pressure plate 16, which is flush with the main pressure plate 3. Figure 4 As shown, a pin 32 is slidably connected to the top wall of the device body 1. A handle 29 is connected to one end of the pin 32 on the outer side. The first sliding plate 18 has several insertion holes 31, which cooperate with the pin 32. A second spring 30 is sleeved on the outside of the pin 32. The two ends of the second spring 30 are connected to the handle 29 and the device body 1, respectively. Pulling the handle 29 outward causes the second spring 30 to extend, allowing the pin 32 to be pulled out of the insertion hole 31. Pulling the extension box 14 causes the first sliding plate 18 and the second sliding plate 13 to slide outward along the second sliding groove 4 and the third sliding groove 9, respectively, so that the pin 32 is aligned with the insertion hole 31 in the appropriate position. At this time, releasing the handle 29 causes the second spring 30 to rebound, allowing the pin 32 to insert into the insertion hole 31 and restrict the sliding of the first sliding plate 18, thereby restricting the movement of the extension box 14. By moving the extension box 14, it can accommodate woven bags of different lengths.

[0028] The specific implementation process is as follows:

[0029] In use, pull the pin 32 out of the socket 31 using the handle 29, pull the extension boxes 14 on both sides to make the placement length consistent with the woven bag, and release the handle 29 to insert the pin 32 into the appropriately positioned socket 31. Place the woven bag to be packed on the bottom wall of the equipment body 1, so that the woven bag is positioned between the insert blocks 28 of the same sealing rod 10. Simultaneously activate the first hydraulic rod 2 and the third hydraulic rod 17, so that the main pressure plate 3 and the auxiliary pressure plate 16 press down to squeeze the woven bag. The packing frame 7 presses down with the main pressure plate 3, the insert blocks 28 are inserted into the slots 20, and the locking blocks 23 are locked into the slots 24. At this time, the first hydraulic rod 2 and the third hydraulic rod 17 retract, so that the main pressure plate 3 and the auxiliary pressure plate 16 move upward, and the first magnetic strip 5 separates from the second magnetic strip 6. Activating the second hydraulic rod 19 causes the push plate 8 to push the packing frame 7 forward. The packing frame 7 drives the sealing rod 10 to slide forward, gradually disengaging it from the first slide groove 12 and moving it onto the placement plate 11. After the sealing rod 10 is completely disengaged from the first slide groove 12, the second hydraulic rod 19 retracts, causing the push plate 8 to return to its original position. At this point, the packed woven bags located on the placement plate 11 can be transferred. To remove the packing frame 7, press the button 26, causing the top column 27 to push the locking block 23 out of the locking slot 24. Then, lift the packing frame 7 upwards and release the button 26 to remove the packing frame 7.
