Description

Technical Field

[0001] This utility model belongs to the field of bag making machine production technology, specifically relating to a device for recycling waste materials from bag making machine production. Background Technology

[0002] A bag-making machine is a mechanical device used to produce bags. It processes raw materials through a series of processes such as cutting, sealing, and folding to ultimately produce bags. Bag-making machines are widely used in the packaging industry and can produce various types of food bags, shopping bags, garbage bags, and medicine packaging bags. During the bag-making process, a lot of scraps and waste are generated, which need to be recycled and reused by a recycling device.

[0003] The prior art patent publication number CN216659092U discloses a waste recycling device for a plastic bag making machine. This patent includes a bag making machine, with a support frame fixedly connected to one side of the machine. A worktable is fixedly connected to one side of the support frame. A recycling component is provided on one side of the worktable. The recycling component includes a first spring, a fixed plate fixedly connected to one side of the first spring, a recycling box slidably connected to one side of the fixed plate, a sliding rod fixedly connected to one side of the recycling box, and a second spring provided on one side of the sliding rod. The device is equipped with a fixed extrusion plate, and a telescopic rubber tube is fixedly connected to one side of the extrusion plate. A limit hole is opened on one side of the extrusion plate. This device can cyclically extrude waste. When extrusion is no longer possible, the fixed plate is pulled to move out of the fixed hole, and then the recycling bin is taken out to recycle the waste, thereby improving the utilization rate of the recycling bin. However, in actual use, there are still the following shortcomings: From a practical point of view, uncrushed waste affects subsequent reprocessing and melting processes, and is not easy to be completely recycled, resulting in the waste of reusable materials in the waste, thereby reducing the recycling value of resources.

[0004] Therefore, there is a need for a waste recycling device for bag making machines to solve the problem of the lack of crushing function in existing technologies, which affects the recycling effect. Utility Model Content

[0005] The purpose of this utility model is to provide a device for recycling waste materials from bag making machines, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a waste recycling device for bag making machines, comprising a mounting frame, a protective box fixedly connected to one side of the mounting frame, two support columns fixedly connected to the bottom of both the mounting frame and the protective box, a transmission cylinder fixedly connected inside the mounting frame, a primary crushing mechanism provided at the top of the transmission cylinder, a second servo motor fixedly connected to the outside of the transmission cylinder, a third rotating shaft fixedly connected to the output end of the second servo motor through one side of the transmission cylinder, multiple sets of evenly distributed spiral blades fixedly connected to the outer wall of the third rotating shaft, a fine crushing cylinder fixedly connected between the inner walls of both sides of the protective box, multiple filter holes penetrating through the outer wall of the fine crushing cylinder, a third servo motor fixedly connected to the outside of the protective box, a fourth rotating shaft fixedly connected to the output end of the third servo motor through the outside of the protective box, multiple fine crushing blades fixedly connected to the outer wall of the fourth rotating shaft, and a discharge port fixedly connected to the bottom of the protective box.

[0014] Compared with the prior art, the waste recycling device for bag making machine provided by this utility model has at least the following beneficial effects:

[0015] (1) By setting up a primary crushing mechanism, the waste material of the bag making machine is poured into the feeding trough, and the first servo motor is turned on to drive the first rotating shaft to rotate.

Detailed Implementation

[0023] The present invention will be further described below with reference to the embodiments.

[0024] Please see Figure 1-5This utility model provides a device for recycling waste materials from a bag-making machine, including a mounting frame 1. A protective box 2 is fixedly connected to one side of the mounting frame 1. Two support columns 3 are fixedly connected to the bottom of both the mounting frame 1 and the bottom of the protective box 2. A transmission cylinder 4 is fixedly connected inside the mounting frame 1. A primary crushing mechanism 5 is provided at the top of the transmission cylinder 4. A second servo motor 6 is fixedly connected to the outside of the transmission cylinder 4. A third rotating shaft 7 is fixedly connected to one side of the transmission cylinder 4 through the output end of the second servo motor 6. Multiple sets of evenly distributed spiral blades 8 are fixedly connected to the outer wall of the third rotating shaft 7. A fine crushing cylinder 9 is fixedly connected between the inner walls of both sides of the protective box 2. Multiple filter holes 10 are opened through the outer wall of the fine crushing cylinder 9. A third servo motor 11 is fixedly connected to the outside of the protective box 2. A fourth rotating shaft 12 is fixedly connected to the output end of the third servo motor 11 through the outside of the protective box 2. Multiple fine crushing blades 13 are fixedly connected to the outer wall of the fourth rotating shaft 12. A discharge port 14 is fixedly connected to the bottom of the protective box 2.

[0025] Further as Figure 1 and Figure 2 As shown, it is worth noting that the bottom of each of the multiple support columns 3 is fixedly connected with a shock-absorbing pad. The shock-absorbing pad can effectively absorb and mitigate the vibration generated during the operation of the machine, reduce the vibration transmission of the entire equipment system, reduce the wear and noise of mechanical parts, thereby improving the service life of the equipment and reducing noise pollution in the working environment.

[0026] Further as Figure 1 and Figure 2 As shown, it is worth noting that the conveyor cylinder 4 extends into the fine crushing cylinder 9, which ensures that the waste material can enter the fine crushing stage more directly, avoiding loss or delay of the waste material during the conveying process. This can reduce the material stagnation time in the intermediate stage and improve the material processing efficiency of the entire recycling system.

[0027] Further as Figure 4 As shown, it is worth noting that multiple fine crushing blades 13 can be detachably connected to cutter heads at their outer ends. The cutter heads are bolted to the outer ends of the fine crushing blades 13. Wear and damage to the cutter heads are common in long-term use. With this design, users can replace only the worn parts instead of the entire fine crushing blade 13, thereby reducing maintenance costs.

[0028] As can be seen from the above working process: by setting up the fine crushing cylinder 9, the waste material after primary crushing is transported to the interior of the fine crushing cylinder 9 through the transmission cylinder 4. The third servo motor 11 is turned on to drive the fourth rotating shaft 12 to rotate, so that multiple fine crushing blades 13 finely crush the waste material. The filter holes 10 screen the finely crushed waste material, processing the waste material into smaller and more uniform particles, which helps to improve the utilization rate in the subsequent recycling process, avoids the waste of waste residue, and improves the purity and quality of the recycled products. Through the dual crushing process of primary crushing and fine crushing, the waste material is fully decomposed in the entire processing process, reducing the energy and resource consumption required in the subsequent processing stage.

[0029] Further as Figure 5 As shown, it is worth noting that the primary crushing mechanism 5 includes a feeding trough 501 fixedly connected to the top of the conveying cylinder 4. A cover plate 502 is rotatably connected to the top of the feeding trough 501. A convex frame 503 is fixedly connected to the rear end of the feeding trough 501. A first rotating shaft 504 and a second rotating shaft 505 are rotatably connected between the rear surface of the front end of the feeding trough 501 and the front surface of the rear end of the convex frame 503. A drive gear 506 is fixedly connected to the outer wall of the first rotating shaft 504, and a driven gear 507 is fixedly connected to the outer wall of the second rotating shaft 505. The first crushing roller 508 is connected to the first crushing roller 508, and the second crushing roller 509 is fixedly connected to the outer wall of the second rotating shaft 505. The first servo motor 510 is fixedly connected to the rear end of the convex frame 503. By setting the primary crushing mechanism 5, the first crushing roller 508 and the second crushing roller 509 rotate simultaneously in opposite directions, thereby performing preliminary crushing of the waste. The primary crushing process cuts and crushes the waste in a large way, reducing the workload of the equipment in the subsequent fine crushing process, reducing the burden on the fine crushing equipment, improving the overall recycling efficiency, and improving the stability and service life of the system.

[0030] Further as Figure 5 As shown, it is worth noting that both the drive gear 506 and the driven gear 507 are located at the rear end of the feeding trough 501, and the drive gear 506 and the driven gear 507 mesh with each other, which can ensure that the first rotating shaft 504 and the second rotating shaft 505 can rotate in opposite directions at the same time, thereby providing driving force for the crushing operation of the first crushing roller 508 and the second crushing roller 509.

[0031] Further as Figure 5 As shown, it is worth noting that both the first crushing roller 508 and the second crushing roller 509 are located inside the feeding trough 501 to ensure that the waste is fully crushed before entering the conveying cylinder. The two sets of crushing rollers, through rotation and compression, help to cut and tear the waste better, thus improving the crushing efficiency.

[0032] Further as Figure 5As shown, it is worth noting that the output end of the first servo motor 510 is fixedly connected to the first rotating shaft 504 through the convex bracket 503, ensuring that the first servo motor 510 can drive the first rotating shaft 504 to rotate smoothly and provide power for the drive gear 506.

[0033] The working process of this solution is as follows: In actual use, the waste material of the bag making machine is poured into the feeding trough 501. The first servo motor 510 is turned on to drive the first rotating shaft 504 to rotate. With the cooperation of the drive gear 506 and the driven gear 507, the first crushing roller 508 and the second crushing roller 509 rotate in opposite directions at the same time, thereby performing preliminary crushing of the waste material. The waste material after preliminary crushing falls into the transmission cylinder 4. The second servo motor 6 drives multiple sets of spiral blades 8 to rotate, conveying the waste material into the fine crushing cylinder 9. The third servo motor 11 is turned on to drive the fourth rotating shaft 12 to rotate, so that multiple fine crushing blades 13 finely crush the waste material. The filter holes 10 screen the finely crushed waste material, processing the waste material into smaller and more uniform particles. The finely crushed waste material is discharged from the discharge port 14 for further utilization.

[0034] In summary: By setting up the primary crushing mechanism 5, the first crushing roller 508 and the second crushing roller 509 rotate simultaneously in opposite directions, thereby initially crushing the waste. The primary crushing process roughly cuts and crushes the waste, reducing the workload of the equipment in the subsequent fine crushing process, reducing the burden on the fine crushing equipment, improving the overall recycling efficiency, and enhancing the stability and service life of the system. By setting up the fine crushing cylinder 9, the waste after primary crushing is transported to the interior of the fine crushing cylinder 9 through the transmission cylinder 4. The third servo motor 11 is turned on to drive the fourth rotating shaft 12 to rotate, so that multiple fine crushing blades 13 finely crush the waste, and the filter holes 10 screen the finely crushed waste, processing the waste into smaller and more uniform particles, which helps to improve the utilization rate in the subsequent recycling process, avoids the waste of waste residue, and improves the purity and quality of the recycled products. Through the dual crushing process of primary crushing and fine crushing, the waste is fully decomposed in the entire processing process, reducing the energy and resource consumption required in the subsequent processing stages.
