Description

Technical Field

[0001] This utility model relates to the field of recycling, and in particular to a waste recycling device for the production of modified polyethylene film. Background Technology

[0002] This waste recycling device for modified polyethylene film production is mainly used to collect and process waste film scraps, damaged film, etc. generated during the production process. It is widely used in the end of the modified polyethylene film production line and in the quality inspection process. It can reduce the volume of waste materials by cutting and compacting, which facilitates subsequent transportation and reprocessing, reduces raw material waste, and improves the economic efficiency and environmental protection of production.

[0003] To improve the recycling device, existing technologies have optimized the arrangement of the cutting blades, replacing the parallel arrangement with an interlaced arrangement to improve cutting efficiency. At the same time, the tilt angle of the waste conveying channel has been improved, the smoothness of the inner wall of the channel has been adjusted to reduce the resistance of waste conveying, and the sealing structure of the device housing has been strengthened by increasing the thickness of the rubber sealing ring to improve the dustproof effect.

[0004] The main drawback of this recycling device is its insufficient capacity to process soft waste. Because the modified polyethylene film waste is soft, it is easy to get tangled on the blades during the cutting process. As the amount of tangling increases, the blades will be obstructed from rotating, eventually causing the machine to jam. When manually cleaning the waste tangled on the sharp blades, the operators are very likely to be cut by the blades. The lack of an effective protective structure to avoid such risks makes it difficult to guarantee the safety of the operators. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a waste recycling device for modified polyethylene film production, which aims to solve the problem in the prior art that the soft material easily entangles the cutting tools, posing a great safety hazard to workers when cleaning the tools.

[0006] To achieve the above objectives, this utility model adopts the following technical solution: a waste recycling device for modified polyethylene film production, comprising an operating table, the top of which is provided with a blade telescopic mechanism and a roller lifting mechanism.

The outer wall of the screw fixing block is fixedly connected to the outer wall of the motor bracket. The inner wall of the screw fixing block is threaded with a fixing screw. The outer wall of the screw fixing block is detachably connected to the motor slider through the fixing screw.

[0010] As a further description of the above technical solution: The roller lifting mechanism also includes a crushing shaft slot, which is located on the outer crushing shaft near the crusher motor. The outer wall of the crushing shaft drive shaft is slidably connected to the inner surface of the crushing shaft slot.

[0011] As a further description of the above technical solution: The roller lifting mechanism also includes a threaded rod motor.

The position of the product collection trough is adapted to the discharge port of the melting and discharging box.

[0014] This utility model has the following beneficial effects: 1. In this utility model, by setting a blade telescopic mechanism, the telescopic control rod can retract the blade when needed, which can effectively prevent soft waste from getting tangled on the blade, prevent mechanical jamming due to excessive tangling, ensure the continuous and stable operation of the device, and at the same time prevent operators from coming into contact with sharp blades, greatly reducing the risk of being cut and improving the safety of the operation process.

The crushing outer shaft 214 slides on the outer wall of the blade roller lifting plate 213, so that the crushing blades 218 can flexibly adapt to the waste. The crushed waste is discharged through the discharge slide 219 fixed to the operating table 1.

[0023] By starting the threaded rod motor 318, the threaded rod motor 318 drives the lifting threaded rod 319 to rotate. The lifting threaded rod 319 is threadedly connected to the blade roller lifting plate 213, causing the lifting plate to rise and fall along the lifting guide rod 320. The motor slider 312 on the motor bracket 311 can drive the crusher motor 313 to slide and adjust its height. The crushing shaft drive shaft 316 at its output end is inserted into the crushing shaft slot 317 of the crushing outer shaft 214 to transmit power. The fixing screw 315 on the screw fixing block 314 can be tightened to fix the motor slider 312, and unscrewed for easy adjustment, providing ample space for component maintenance.
