Description
Technical Field
[0001] The utility model relates to the technical field of plastic recycling, in particular to a waste plastic recycling crusher. Background Art
[0002] Plastic is a common material, widely used in home appliances, automobiles, mobile phones, PCs, medical equipment, lighting appliances and other fields. Due to the large number of plastic applications, many waste plastic parts are generated. The main methods of treating waste plastics at home and abroad include chemical raw material recycling, physical landfill, composite modification, combustion energy recovery and mechanical physical recycling. The mechanical physical recycling method is to reprocess the waste plastics after crushing, cleaning, screening and classification, re-granulation and other process flows. It can be used directly as raw materials or in combination with new materials.
[0003] The Chinese patent CN 215039368 U proposes "a highly efficient crusher for the production of plastic products, including a device body, a fixed knob and a reflective cursor. The bottom of the device body is movably connected to the fixed knob, and the top of the device body is fixedly connected to a mechanical crushing device. The mechanical crushing device is composed of a motor, a rotator, a crushing rod, and a crushing bucket, which are used in conjunction with each other to form a crushing mechanism. When the user needs to turn on the machine to crush plastic products, first manually press the switch, then the crushing mechanism starts working, and then the plastic products to be crushed are poured into the crushing bucket. During the operation, the motor drives the rotator to rotate, and the rotator drives the crushing rod to rotate. The crushing rod rotates and crushes the plastic products in the crushing bucket. By adding such a setting, the crushing mechanism can be turned on to crush the plastic products efficiently, so that the waste plastic products can be recycled more conveniently."
[0004] Plastic crushers in the prior art can crush plastics for recycling, but some plastic products are embedded with metal parts. These metal parts are originally connectors of plastic parts or mechanical structures in plastic products. They are connected to the plastic parts and are difficult to separate. After the crushers in the prior art crush the plastic products, these metal parts will flow into the next process together with the plastic fragments. If they are not removed, it will be detrimental to the recycling of plastics. Therefore, a plastic crusher that can automatically separate metal parts is needed. Utility Model Content

A hanging ring 12 is fixedly provided on the top of the collecting box 11.
[0039] Principle and process of the utility model: when in use, first fill the crushing box 2 and the sedimentation box 3 with water, open the rough processing module 4 and the fine processing module 6, and then put the waste plastic products into the rough processing module 4. The rough processing module 4 is a crusher structure in the prior art. The rough processing module 4 can perform preliminary processing on the waste plastic and crush it into large plastic fragments. The large plastic fragments processed by the rough processing module 4 fall into the crushing box 2 and float on the water surface, while the large metal pieces peeled off by the rough processing module 4 sink under the water. When the fine processing module 6 is started, the first crushing roller 62 and the second crushing roller 63 are driven to rotate by the motor 61, and the second crushing roller 63 drives the main shaft 51 to rotate through the first pulley 71, the belt 72 and the second pulley 73. After the main shaft 51 rotates, the feeding mechanism 5 is operated. When the feeding mechanism 5 is in operation, the main shaft 51 drives the push plate 54 to rotate through the support rod 52 and the bracket 53, and the push plate 54 rotates counterclockwise around the circumferential direction of the main shaft 51 (reference Figure 4When the push plate 54 rotates, it pushes the large plastic fragments floating on the water surface to the finishing module 6, and the first crushing roller 62 and the second crushing roller 63 crush the large plastic fragments moved between the two into small plastic fragments. In the process, the small metal pieces embedded in the plastic fragments are peeled out and sink to the bottom of the water, and the small plastic fragments obtained after processing float to the top of the discharge box 84, and the small plastic fragments are recovered by the discharge mechanism 8. By setting the rough processing module 4 and the finishing module 6, the metal parts embedded in the plastic parts can be peeled out.
[0040] The small pieces of plastic fragments obtained after processing by the fine processing module 6 will eventually float to the top of the discharge box 84. The specific operation of using the discharge mechanism 8 to recycle the small pieces of plastic fragments is as follows: when the small pieces of plastic fragments floating above the discharge box 84 accumulate to a certain amount, the electric telescopic column 81 is turned on, and the output end of the electric telescopic column 81 drives the support seat 82 to rise, and the support seat 82 lifts the discharge box 84 out of the water through the ear seat 83. When the accumulated water is drained from the bottom of the discharge box 84, only small pieces of plastic fragments are left in the discharge box 84. Then the staff can lift the discharge box 84 from the support seat 82 and move it to the recycling processing system. The metal parts that sink to the bottom of the water will fall onto the inclined surface at the bottom of the crushing box 2, then enter the sedimentation box 3 through the inclined surface, and finally fall into the collection box 11. When a certain amount of metal parts are collected in the collection box 11, the staff needs to press the push rod 10 downward first, so that the baffle 9 blocks the connection between the crushing box 2 and the sedimentation box 3, and then use the hook rope and hanging ring 12 to pull the collection box 11 out of the water, and recycle the metal parts in the collection box 11. After the recycling is completed, the collection box 11 is put back to the bottom of the sedimentation box 3, and the baffle 9 is lifted by the push rod 10.
