Description

Technical Field

[0001] This utility model belongs to the field of feeding technology for folded bag opening machines, specifically relating to an adjustable feeding device for folded bag opening machines. Background Technology

[0002] A folded bag opening machine is an automated device used in the production process of plastic packaging bags (especially folded bags). Its main function is to open the edges of folded packaging bags to facilitate subsequent filling, sealing and other processes. The feeding device of the folded bag opening machine is one of the core components. It is mainly used to automatically feed, sort and transport folded bags (such as plastic folded bags, paper folded bags, etc.), ensuring that the bags can enter the subsequent processes accurately and stably during the opening process, thereby improving production efficiency and automation.

[0003] In practical applications of edge-folding bag opening machines, traditional feeding devices generally employ a single storage bin feeding mode, which suffers from significant efficiency bottlenecks and accuracy deficiencies. On one hand, once all the edge-folding bags in the storage bin have been fed, the operator must pause the equipment, remove the entire feeding device, and reload the bags. This process is not only time-consuming and labor-intensive but also causes the opening machine to idle for extended periods, drastically reducing the continuity of the production line and overall capacity. On the other hand, traditional feeding devices lack a sophisticated edge-folding bag positioning and regulating structure, failing to effectively constrain stacked edge-folding bags. This leads to bag displacement and tipping within the storage bin, resulting in high bag positional dispersion. This positional deviation directly interferes with the accuracy of subsequent suction cup gripping actions, causing the suction cups to fail to accurately pick up the edge-folding bags, leading to gripping failures, bag damage, and other problems, severely impacting production efficiency and packaging quality. Furthermore, frequent manual intervention and equipment downtime increase operating costs and equipment wear, making it difficult to meet the demands of modern automated packaging production lines for high efficiency, stability, and precision. Utility Model Content

[0004] The purpose of this invention is to provide an adjustable feeding device for a folded bag opening machine, aiming to solve the following problems in the existing technology: Firstly, after all the folded bags in the storage bin have been fed, the operator needs to stop the equipment, remove the entire feeding device, and refill the folded bags. This process is not only time-consuming and labor-intensive but also causes the opening machine to run idle for a long time, significantly reducing the continuity of the production line and overall capacity. Secondly, traditional feeding devices lack a precise folded bag positioning and regulating structure, failing to effectively constrain stacked folded bags. This leads to folded bags easily shifting or tipping over in the storage bin, resulting in high bag position dispersion.

[0005] To achieve the above objectives, the present invention provides the following technical solution: an adjustable feeding device for a folding bag opening machine, comprising a feeding machine body and universal rollers installed on the outer bottom surface of the feeding machine body, a controller being installed on the outer wall of the feeding machine body, and a partition being installed on the inner wall of the feeding machine body;

[0006] The inner wall of the feeding machine body is connected to a limit frame. The bottom surface of the feeding machine body is connected to a lifting motor. The output end of the lifting motor is connected to a lead screw. The surface of the lead screw is connected to a threaded block. One side of the threaded block is connected to a support plate. The surface of the support plate is connected to a positioning plate. The inner wall of the opening of the positioning plate is connected to a sliding plate. One end of the sliding plate is connected to a linkage plate. The bottom surface of the sliding plate is connected to a clamping spring. The bottom surface of the clamping spring is connected to a fixed rod. The bottom surface of the fixed rod is connected to a roller bracket. The inner side of the roller bracket is rotatably connected to a roller.

[0009] As a preferred embodiment of the adjustable folding bag opening machine feeding device of this utility model, each of the linkage plates is connected to two rollers on its bottom surface, and the rollers are made of silicone.

[0010] As a preferred embodiment of the adjustable folding bag opening machine feeding device of this utility model, the linkage plate is connected to a docking plate on the side near the sliding plate, and the linkage plate slides and docks with the opening on one side of the sliding plate through the docking plate.

[0011] As a preferred embodiment of the adjustable folding bag opening machine feeding device of this utility model, a fixed block is connected to the surface of the sliding plate, a movable rod is movably connected to the surface of the fixed block, a linkage insert plate is connected to the other end of the movable rod, a linkage spring is connected to the surface of the linkage insert plate, and the other end of the linkage spring is connected to the inner wall of the fixed block.

[0012] As a preferred embodiment of the adjustable folding bag opening machine feeding device of this utility model, the surface of the docking plate near the linkage plate is provided with a slot, and the linkage plate and the slot form a fitting structure.

[0013] Compared with the prior art, the beneficial effects of the present invention are:

[0014] This invention moves the feeding machine to the bottom of the folding and opening machine, then places the bags to be folded into the storage slots on both sides of the partition inside the feeding machine. At this time, the sliding plate inside the positioning plate slides up and down to limit, clamp, and arrange the stored bags to be folded. Then, the lifting motor is driven to rotate the lead screw, which in turn moves the threaded blocks on both sides of the tray along the lead screw, causing the bags to be folded on the tray surface to rise. Then, the mechanical suction cup of the opening machine feeds the bags to be folded. After one storage slot is filled, the feeding machine is moved to facilitate feeding the bags to be folded into the other storage slot. At the same time, personnel continue to fill the empty storage slots, achieving the effect of folding and opening without stopping the machine, thus improving the opening effect.

[0026] A limit frame 5 is connected to the inner side of the feeding machine body 1. A lifting motor 6 is connected to the bottom surface of the feeding machine body 1. A lead screw 7 is connected to the output end of the lifting motor 6. A threaded block 81 is connected to the surface of the lead screw 7. A support plate 8 is connected to one side of the threaded block 81. A positioning plate 9 is connected to the surface of the support plate 8. A sliding plate 10 is connected to the inner wall of the opening of the positioning plate 9. A linkage plate 11 is connected to one end of the sliding plate 10. A clamping spring 12 is connected to the bottom surface of the sliding plate 10. A fixing rod 13 is connected to the bottom surface of the clamping spring 12. A roller bracket 14 is connected to the bottom surface of the linkage plate 11. A roller 15 is rotatably connected to the inner side of the roller bracket 14.

[0027] Preferably, each pallet 8 has a threaded block 81 connected to both sides. The threaded block 81 is threadedly connected to the lead screw 7, and the threaded block 81 and the opening in the inner wall of the limiting frame 5 form a sliding connection structure. In actual use, the lifting motor 6 is driven, which drives the lead screw 7 to rotate, thereby facilitating the movement of the pallet 8 and achieving the purpose of automatic feeding.

[0028] Preferably, the sliding plate 10 and the positioning plate 9 form a sliding connection structure, the sliding plate 10 and the clamping spring 12 form an elastic telescopic structure, and the bottom end of the fixing rod 13 is connected to the bottom end of the inner wall of the positioning plate 9. In actual use, by sliding the sliding plate 10 along the positioning plate 9, and at the same time, according to the elastic telescopic structure of the clamping spring 12 itself, the folded bag can be easily and neatly positioned.

[0029] Preferably, each linkage plate 11 has two rollers 15 connected to its bottom surface, and the rollers 15 are made of silicone. In actual use, the rollers 15 are used to ensure that the folded bag is clamped and positioned.

[0030] Preferably, a docking plate is connected to the side of the linkage plate 11 near the sliding plate 10, and the linkage plate 11 slides and docks with an opening on one side of the sliding plate 10 through the docking plate. In actual use, the docking plate docks with the opening on one side of the sliding plate 10, thereby ensuring the stable movement of the linkage plate 11.

[0031] Preferably, a fixed block 16 is connected to the surface of the sliding plate 10, a movable rod 17 is movably connected to the surface of the fixed block 16, a linkage insert 18 is connected to the other end of the movable rod 17, a linkage spring 19 is connected to the surface of the linkage insert 18, and the other end of the linkage spring 19 is connected to the inner wall of the fixed block 16. In actual use, when the linkage plate 11 needs to be adjusted, the elastic force of the linkage spring 19 facilitates the automatic insertion of the linkage insert 18.

[0032] Preferably, a slot 20 is provided on the surface of the mating plate near the linkage plate 18, and the linkage plate 18 and the slot 20 form a fitting structure.

Then, the linkage plate 18 is fitted into the surface of the slot 20, which facilitates the stable installation of the linkage plate 11.

[0033] The working principle of this utility model is as follows: The feeding machine body 1 is moved to the bottom of the folding and opening machine. The bags to be folded are then placed in the storage slots on both sides of the partition 4 inside the feeding machine body 1. At this time, the sliding plate 10 inside the positioning plate 9 slides up and down to limit, clamp, and arrange the stored bags. The lifting motor 6 is then driven, causing the lead screw 7 to rotate, which in turn moves the threaded blocks 81 on both sides of the tray 8 along the lead screw 7. This causes the bags to be folded on the surface of the tray 8 to rise. The mechanical suction cups of the opening machine then feed the bags. Once one storage slot is filled, the feeding machine body 1 is moved to facilitate further feeding. The bag to be folded is fed into another storage tank, while personnel continue to fill the empty storage tank, achieving the effect of folding and opening without stopping the machine, thus improving the opening effect. At the same time, by pulling the linkage plate 11, the docking plate slides on the opening of the sliding plate 10. Simultaneously, the movable rod 17 on the surface of the fixed block 16 is pulled, which in turn causes the linkage plate 18 to squeeze the linkage spring 19. At this time, the linkage plate 18 is disengaged from the opening of the slot 20. The linkage plate 11 is then stretched in length, which facilitates the limiting clamping of folded bags of different specifications. At this time, the roller 15 on the bottom surface of the linkage plate 11 limits and clamps the folded bags, thus ensuring the practicality of the feeding device.
