Description

Technical Field

[0001] This utility model relates to the technical field of feeding auxiliary equipment, and in particular to a polyethylene feeding auxiliary device for the production of plastic packaging bags. Background Technology

[0002] In the production of plastic packaging bags, polyethylene is the main raw material, and the smoothness of its feeding process directly affects production efficiency and product quality. Traditional plastic packaging bag production equipment often encounters problems in the feeding stage, which to some extent restricts the improvement of production efficiency and product quality.

[0003] Traditional feeding devices are typically simple in design and lack effective auxiliary feeding measures. When polyethylene raw materials are fed into production equipment, factors such as particle size and moisture content can easily lead to feeding difficulties or blockages. This not only causes production line shutdowns and affects production efficiency, but may also cause equipment failures due to raw material accumulation, increasing maintenance costs.

[0004] During the feeding process, polyethylene raw materials may accumulate or agglomerate, forming hard lumps. These lumps are difficult to disperse evenly after entering the production equipment, thus affecting the uniformity and quality of the product. However, traditional feeding devices often lack a mixing function and cannot pre-treat the raw materials, making this problem difficult to solve effectively. Traditional feeding devices also present certain inconveniences in terms of installation and maintenance. Due to design limitations, these devices are often difficult to connect stably to the production equipment, and disassembly and replacement require a significant amount of time and effort. Furthermore, the adjustment and maintenance of the drive components lack convenience, increasing operational difficulty and costs.

[0005] During the feeding process, the fluidity of the raw materials and the potential for blockage pose certain safety hazards. Traditional feeding devices are insufficiently designed for safety, lacking effective limiting and protective measures, which can easily lead to safety accidents. Therefore, we provide a polyethylene feeding auxiliary device for plastic packaging bag production. Utility Model Content

[0006] To address the aforementioned problems, this utility model proposes a polyethylene feeding auxiliary device for the production of plastic packaging bags, which more accurately solves the problems mentioned in the background art.

[0007] This utility model is achieved through the following technical solution:

[0008] The utility model proposes a polyethylene feeding auxiliary device for the production of plastic packaging bags, including a packaging bag production machine. The upper surface of the packaging bag production machine is provided with a feeding port for feeding materials. An auxiliary feeding hopper is inserted into the inner wall of the feeding port. A limit frame plate is fixedly welded to the periphery of the auxiliary feeding hopper to prevent excessive insertion of the auxiliary feeding hopper.

[0009] A vertical limiting mechanism is connected between the packaging bag production machine and the auxiliary feeding hopper;

[0010] The auxiliary feed hopper is equipped with a stirring structure to prevent the feed hopper from becoming clogged.

[0011] The vertical limiting mechanism includes a limiting insertion hole on the lower periphery of the auxiliary feeding hopper and a placement groove on the upper surface of the packaging bag production machine. A fixing rod is fixedly connected between the two end walls of the placement groove. A spring is sleeved around the fixing rod. A movable sleeve block is slidably sleeved around the fixing rod. A fixing plate is fixedly welded to the upper surface of the movable sleeve block. A limiting insertion rod is fixedly connected to the surface of the fixing plate.

[0012] Furthermore, the stirring structure includes a stirring rod rotatably connected to the auxiliary feed hopper via a bearing, with stirring blades fixedly welded to the periphery of the stirring rod, and a drive component connecting the packaging bag production machine and the end of the stirring rod.

[0013] Furthermore, the driving component includes a T-shaped groove formed on the upper surface of the packaging bag production machine, a T-shaped slider slidably connected to the inner wall of the T-shaped groove, an mounting plate fixedly installed on the upper end of the T-shaped slider, and a drive motor fixedly installed on the upper end of the mounting plate.

[0014] Furthermore, the driving component also includes a prismatic groove block fixedly welded to the end of the stirring rod, and the output end of the driving motor is fixedly connected to a prismatic insert block, which is inserted into the inner wall of the prismatic groove block.

[0015] Furthermore, the drive component also includes a through hole on the surface of the mounting plate and a threaded hole on the upper surface of the packaging bag production machine. A torque screw is installed on the inner wall of the through hole, and the lower end of the torque screw passes through the through hole and is threaded to the inner wall of the threaded hole.

[0016] Furthermore, one end of the limiting rod is inserted into the inner wall of the limiting hole, one end of the spring is fixedly connected to the end wall of the mounting groove, and the other end of the spring is fixedly connected to one end surface of the movable sleeve.

[0017] The beneficial effects of this utility model are:

[0018] This invention significantly improves feeding efficiency and effectively prevents clogging by incorporating an auxiliary feeding hopper and a stirring structure. The insertion design of the auxiliary feeding hopper, combined with a limiting frame, ensures a stable connection between the hopper and the packaging bag production machine, preventing shaking or detachment during the feeding process. Meanwhile, the stirring rod and blades in the stirring structure rotate under the drive of the driving component, continuously stirring the polyethylene within the auxiliary feeding hopper. This effectively prevents clogging caused by polyethylene accumulation or clumping, ensuring the continuity and stability of the production process and improving production efficiency.

[0019] This invention achieves rapid installation and disassembly of the auxiliary feeding hopper through the cooperation of springs, movable sleeves, and limiting rods, making operation simple and convenient. Simultaneously, the dual limiting design of the limiting frame plate and limiting rods ensures the stability and safety of the auxiliary feeding hopper. The drive component, through the cooperation of T-shaped grooves, T-shaped sliders, and torsion screws, allows for flexible adjustment and fixation of the drive motor position, ensuring stable operation of the stirring structure. The connection method between the prismatic groove block and the prismatic insert block ensures both accurate transmission and easy disassembly and maintenance. The overall design improves operational convenience while ensuring the safety and reliability of the equipment. Attached Figure Description

[0026] To more clearly and completely illustrate the technical solution of this utility model, the following description, in conjunction with the accompanying drawings, will further explain this utility model.

[0027] Example

[0028] like Figures 1-5 As shown in the figure, an embodiment of this utility model discloses a polyethylene feeding auxiliary device for plastic packaging bag production, including a packaging bag production machine 1. The upper surface of the packaging bag production machine 1 has a feeding port 2 for feeding materials. An auxiliary feeding hopper 3 is inserted into the inner wall of the feeding port 2. A limiting frame plate 4 is fixedly welded to the periphery of the auxiliary feeding hopper 3. When the auxiliary feeding hopper 3 is inserted into the feeding port 2, the limiting frame plate 4 contacts the upper surface of the packaging bag production machine 1, thereby preventing over-insertion of the auxiliary feeding hopper 3. A vertical limiting mechanism is connected between the packaging bag production machine 1 and the auxiliary feeding hopper 3. The vertical limiting mechanism includes a limiting insertion hole 5 on the lower periphery of the auxiliary feeding hopper 3 and a mounting groove 6 on the upper surface of the packaging bag production machine 1. A fixing rod 7 is fixedly connected between the two end walls of the mounting groove 6. A spring 8 is sleeved around the fixing rod 7. A movable sleeve block 9 is slidably sleeved around the fixing rod 7. A fixing plate 10 is fixedly welded to the upper surface of the movable sleeve block 9. A limiting rod 11 is fixedly connected to the surface of the fixing plate 10. When the auxiliary feeding hopper 3 needs to be installed on the packaging bag production machine 1, the fixing plate 10 is pulled outward. The fixing plate 10 drives the movable sleeve block 9 to slide on the fixing rod 7, while compressing the spring 8. Then, the auxiliary feeding hopper 3 is inserted into the feeding port 2. When the limiting insertion hole 5 corresponds to the position of the limiting rod 11, the fixing plate 10 is released. Under the elastic force of the spring 8, the movable sleeve block 9 drives the fixing plate 10 and the limiting rod 11 to move, so that one end of the limiting rod 11 is inserted into the inner wall of the limiting insertion hole 5, thereby realizing the vertical limiting of the auxiliary feeding hopper 3.

[0029] Furthermore, a stirring structure is installed inside the auxiliary feeding hopper 3 to prevent clogging of the feed into the auxiliary feeding hopper 3. The stirring structure includes a stirring rod 12 rotatably connected to the auxiliary feeding hopper 3 via bearings. Stirring blades 13 are fixedly welded to the periphery of the stirring rod 12. A driving component is connected between the packaging bag production machine 1 and the end of the stirring rod 12. When the driving component drives the stirring rod 12 to rotate, the stirring rod 12 drives the stirring blades 13 to rotate within the auxiliary feeding hopper 3, stirring the polyethylene within the auxiliary feeding hopper 3 and preventing clogging of the polyethylene within the auxiliary feeding hopper 3.

[0030] Furthermore, the driving component includes a T-shaped groove 14 formed on the upper surface of the packaging bag production machine 1. A T-shaped slider 15 is slidably connected to the inner wall of the T-shaped groove 14. A mounting plate 16 is fixedly installed on the upper end of the T-shaped slider 15, and a drive motor 17 is fixedly installed on the upper end of the mounting plate 16. By sliding the T-shaped slider 15 within the T-shaped groove 14, the positions of the mounting plate 16 and the drive motor 17 can be adjusted to facilitate the connection between the drive motor 17 and the end of the stirring rod 12.

[0031] Furthermore, the driving component also includes a prismatic groove block 18 fixedly welded to the end of the stirring rod 12. A prismatic insert block 19 is fixedly connected to the output end of the driving motor 17, and the prismatic insert block 19 is inserted into the inner wall of the prismatic groove block 18. When the driving motor 17 operates, the output end of the driving motor 17 drives the prismatic insert block 19 to rotate. The prismatic insert block 19 rotates within the prismatic groove block 18, thereby driving the stirring rod 12 and the stirring blade 13 to rotate, thus achieving stirring of the polyethylene in the auxiliary feed hopper 3.

[0032] Furthermore, the drive component also includes a through hole 20 formed on the surface of the mounting plate 16 and a threaded hole 21 formed on the upper surface of the packaging bag production machine 1. A torque screw 22 is installed on the inner wall of the through hole 20, and the lower end of the torque screw 22 passes through the through hole 20 and is threaded into the inner wall of the threaded hole 21. After the position of the mounting plate 16 is adjusted so that the prismatic insert 19 is inserted into the prismatic groove block 18, the torque screw 22 is passed through the through hole 20 and screwed into the threaded hole 21, thereby fixing the mounting plate 16 on the packaging bag production machine 1 and preventing the drive motor 17 from moving during operation.

[0033] Furthermore, one end of the limiting rod 11 is inserted into the inner wall of the limiting hole 5, one end of the spring 8 is fixedly connected to the end wall of the mounting groove 6, and the other end of the spring 8 is fixedly connected to one end surface of the movable sleeve block 9. When it is necessary to disassemble the auxiliary feed hopper 3, pull the fixing plate 10 outward. The fixing plate 10 drives the movable sleeve block 9 to slide on the fixing rod 7, while compressing the spring 8, so that one end of the limiting rod 11 is pulled out from the limiting hole 5, and then the auxiliary feed hopper 3 can be taken out from the feed inlet 2. When it is necessary to install the auxiliary feed hopper 3, repeat the above installation steps.
