Description

Technical Field

[0001] The present application relates to the technical field of packaging bag processing, and in particular to a production device and method for degradable industrial packaging bags. Background Art

[0002] In the field of plastic packaging production, in order to meet different functional requirements, various plastic additives need to be added and mixed. At the same time, with the improvement of environmental protection requirements and the popularization of resource recycling concepts, the recycling and reuse of plastic waste has also become an important link in the production process. Mixing recycled plastic waste with new raw materials after treatment can not only reduce production costs but also help reduce environmental pollution. In this context, the integrated raw material mixer for packaging bag production has become a key equipment. However, the mixers in the existing technology have many defects, which seriously affect the production efficiency, mixing quality and waste recycling effect. In general, the structure of the existing integrated mixer for raw materials used in packaging bag production is relatively simple, and the mixing and stirring mechanism is relatively single. During the mixing and stirring process, this single stirring mechanism is difficult to achieve sufficient mixing of the materials, especially when the mixed raw materials include recycled plastic waste. Due to the differences in physical properties, shape and size between the waste and the new raw materials, the single stirring mechanism is even more difficult to ensure mixing uniformity. In order to meet the basic mixing requirements, the mixing and stirring working time has to be extended, which greatly reduces the processing efficiency. In addition, when adding mixed materials, most of the existing equipment directly feeds the raw materials into the processing equipment. This feeding method is very likely to cause material accumulation. When the raw materials contain recycled plastic waste, the waste may aggravate the accumulation due to irregular shapes, etc., which not only affects the mixing efficiency, but also reduces the mixing area and further increases the mixing time. At the same time, it is difficult to ensure mixing uniformity, which greatly limits the application of the equipment in actual work and is not conducive to giving full play to the advantages of plastic waste recycling. Taking the mixer disclosed in Chinese patent publication number "CN218875947U" as an example, although the device improves the mixing and stirring effect to a certain extent through the coordinated use of motor equipment, rotating rod and stirring blades, and enhances working stability through the buffering and shock-absorbing structure, it still exposes obvious defects when processing mixed raw materials containing plastic waste. First, the device lacks a structure for returning the materials up and down. During the mixing process, it cannot effectively cause the materials to roll up and down. Especially for new raw materials and recycled waste with different densities and textures, it is difficult to achieve rapid and uniform mixing of the upper and lower layers of materials, which reduces the mixing efficiency and quality and affects the fusion effect of the waste and new raw materials. Second, its bottom stirring frame is arranged horizontally, and the main body of the device is usually a cylindrical tank structure. This design makes it difficult for the bottom stirring structure to fully cover the internal space of the tank, which easily forms a mixing dead corner. As a result, the materials in some areas cannot be fully stirred, which in turn causes uneven mixing and affects the final mixing effect. There are obvious mixing defects, which are not conducive to the efficient utilization of plastic waste after recycling. Summary of the Invention

Its output end drives the active synchronous wheel 54 to rotate, providing initial power for the operation of the equipment. Step 3: The driving synchronous wheel 54 and the driven synchronous wheel 52 are connected to each other through the synchronous belt 55. When the driving synchronous wheel 54 rotates, the driven synchronous wheel 52 is driven to rotate synchronously. The bottom of the driven synchronous wheel 52 is connected to the main shaft 71 of the stirring mechanism 7, which in turn causes the main shaft 71 to start rotating. The stirring plate 72 and the stirring auger 73 fixed to the outer surface of the main shaft 71 are then operated to perform preliminary stirring and bottom agitation of the raw materials in the tank body 3. Step 4: The bottom of the active synchronous wheel 54 is connected to the linkage mechanism 6. The slip ring 61 in the linkage mechanism 6 is rotatably connected to the inside of the annular rail 2. The rotation of the active synchronous wheel 54 drives the rotating shaft 64 to rotate, and the active bevel gear 62 at the bottom of the rotating shaft 64 rotates accordingly. The active bevel gear 62 drives the driven bevel gear 63 to rotate through meshing transmission. The driven bevel gear 63 is fixed to the shaft body 82 and is located at the outer end of the return pipe 81, thereby rotating the shaft body 82. The return auger 83 fixed on the outer surface of the shaft body 82 rotates in the return pipe 81. The input end of the return pipe 81 is connected to the bottom of the tank body 3, and the output end is connected to the upper end of the tank body 3, so that the raw materials at the bottom of the tank body 3 are transported to the upper part. Step 5: Operate the drive motor 53 to change its driving rotation direction, thereby flexibly adjusting the rotation direction of the return auger 83 and the stirring auger 73. Under the synergistic effect of the two, the raw materials are violently tumbled up and down in the tank body 3, forming a three-dimensional circulation mixing process; Step 6: After the raw materials are fully mixed in the tank body 3, open the discharge valve 10 and use the conical structure at the bottom of the tank body 3 to concentrate the mixed raw materials toward the discharge valve 10. The raw materials pass through the input and output ends of the discharge valve 10 in turn and are discharged through the discharge pipe, completing the entire discharge process of the mixed raw materials.

[0023] The implementation principle of the production equipment and method for degradable industrial packaging bags in the embodiment of the present application is as follows: during the application of the device, when mixing raw materials, the raw materials required for the production of degradable industrial packaging bags, such as degradable plastic particles, various plastic additives, and recycled plastic waste, are first fed into the equipment through the feeding guide bucket 12 on the top of the feeding tube 9. The feeding control valve 11 installed at the lower end of the feeding tube 9 can control the feeding amount and feeding speed of the raw materials. The raw materials enter the interior of the tank body 3 after passing through the feeding control valve 11. At the same time, the feeding tube 9 can be adjusted to close to form sealed stirring after the feeding is completed; after the feeding is completed, the driving mechanism 5 can be started to run. Since the driving motor 53 is installed on the top of the side plate 51 at one end of the top frame 4, when the driving motor 53 is running, its output end is provided with The driving synchronous wheel 54 rotates, and the driving synchronous wheel 54 and the driven synchronous wheel 52 are connected through the synchronous belt 55. Therefore, the rotation of the driving synchronous wheel 54 will drive the driven synchronous wheel 52 to rotate synchronously. The bottom of the driven synchronous wheel 52 is connected to the main shaft 71 of the stirring mechanism 7, so that the main shaft 71 starts to rotate, and the stirring plates 72 fixedly installed on the outer surface of the main shaft 71 at equal intervals and arranged in a ring shape will rotate with the main shaft 71 to perform preliminary stirring on the raw materials in the tank body 3. At the same time, the stirring auger 73 fixedly installed at the lower end of the outer surface of the main shaft 71 also starts to work. The conical structure design of its lower end can better cover the bottom area of ​​the tank body 3, stir the bottom raw materials, and promote the mixing of the raw materials in the lower area of ​​the tank body 3. When the driving synchronous wheel 54 rotates, The bottom of the active synchronous wheel 54 is connected to the linkage mechanism 6, and the linkage mechanism 6 also starts to work. The slip ring 61 in the linkage mechanism 6 is rotatably connected to the inside of the annular rail 2, and the top of the rotating shaft 64 is connected to the bottom of the active synchronous wheel 54. At this time, as the active synchronous wheel 54 rotates, it can drive a rotating shaft 64 to rotate. The rotation of a rotating shaft 64 can drive the active bevel gear 62 at its bottom to rotate. During the rotation of the active bevel gear 62, the driven bevel gear 63 can be driven to rotate. During this period, the active bevel gear 62 can also drive the spur gear 66 to rotate. The rotation of the spur gear 66 can drive the gear ring 65 meshing with it to rotate. The rotation of the gear ring 65 can drive the slip ring 61 to rotate in the annular rail 2. It can be seen that the gear ring 65 fixedly connected to the outside of the slip ring 61 is fixed to the gear ring 65. The spur gear 66 at the bottom of the active bevel gear 62 is meshed with the spur gear 66. When the slip ring 61 rotates, each active bevel gear 62 starts to rotate. The active bevel gear 62 is connected to the driven bevel gear 63. The driven bevel gear 63 is fixedly mounted on the shaft 82 at the outer end of the return tube 81. Therefore, the rotation of the active bevel gear 62 drives the driven bevel gear 63 and the shaft 82 to rotate. A return auger 83 is fixedly mounted on the outer surface of the shaft 82 located inside the tank body 3. The return auger 83 rotates in the return tube 81 driven by the shaft 82. The return tube 81 is concave in shape as a whole. Its input end is connected to the bottom of the tank body 3, and the output end is connected to the upper end of the tank body 3. When the return auger 83 rotates, the raw material at the bottom of the tank body 3 is transported to the upper part of the tank body 3 through the return tube 81.The raw materials are returned to the upper end of the tank body 3 through the return pipe 81, thereby realizing the up and down return of the raw materials. Under the coordinated work of the stirring mechanism 7 and the return mechanism 8, the returned materials fall and can be stirred by the stirring plate 72. By controlling the driving direction of the drive motor 53 during stirring, the rotation direction of the return auger 83 and the stirring auger 73 can be flexibly adjusted, thereby realizing the violent up and down tumbling of the materials, and the raw materials in the tank body 3 are continuously stirred and transported, forming a three-dimensional circulation mixing process in the tank body 3. After the raw materials are fully mixed inside the tank body 3, the discharge valve 10 is opened. Since the bottom of the tank body 3 is conical, it is convenient for the raw materials to be concentrated to the discharge valve 10. The mixed raw materials enter the discharge valve 10 through the input end of the discharge valve 10, and are then discharged from the output end of the discharge valve 10 through the discharge pipe, completing the entire mixing process. This equipment realizes three-dimensional mixing of raw materials through the cooperation of the stirring mechanism 7 and the return mechanism 8. The stirring plate 72 and the stirring auger 73 in the stirring mechanism 7 perform preliminary stirring and bottom stirring on the raw materials, and the return mechanism 8 transports the bottom raw materials to the upper part, so that the raw materials are continuously rolled up and down in the tank body 3. Compared with the existing technology, the mixing uniformity is greatly improved, the extension of the stirring time due to uneven mixing is avoided, and the production efficiency is effectively improved. This equipment can control the direction and speed of raw material input through the design of the feeding guide bucket 12 and the feeding control valve 11, reducing the possibility of raw material accumulation. At the same time, the coordinated work of the stirring mechanism 7 and the return mechanism 8 can quickly disperse the input raw materials, further avoiding the accumulation phenomenon. , ensuring full utilization of the mixing area and improving mixing efficiency. When processing mixed raw materials containing recycled plastic waste, existing equipment has the problem of difficulty in fusing waste materials and new materials and easily forming mixing dead corners. In this technical solution, the return mechanism 8 promotes the full mixing of new materials with different densities and textures with recycled waste. The conical structure of the stirring auger 73 and the cooperation of the return auger 83 can better cover the internal space of the tank body 3, reduce mixing dead corners, and fully fuse the waste materials with the new materials, which is conducive to improving the utilization effect of plastic waste after recycling and realizing efficient recycling of resources. In addition, the support frame 13 at the bottom of the top frame 4 is fixedly connected to the annular rail 2, which enhances the overall stability of the equipment and ensures the long-term stable operation of the equipment.

Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
