Description

Technical Field

[0001] The utility model relates to the technical field of crushers, in particular to a plastic bottle garbage crusher. Background Art

[0002] Plastic bottles are the most common disposable plastic packaging containers in daily life. They are not easy to break, low cost, high transparency, and food-grade raw materials. Since plastic bottles are disposable packaging containers, they are usually discarded after use. However, plastic bottles are difficult to degrade naturally. A large number of discarded plastic bottles will pose a serious threat to the environment. Therefore, plastic bottles need to be recycled and reused. When processing recycled plastic bottles, a crusher is needed to crush the waste plastic bottles.

[0003] After searching, the existing patent (publication number: CN214521333U) discloses a plastic bottle crusher. When using this solution, the crushing roller is used to crush the plastic bottles, and before crushing the plastic bottles, they are squeezed to flatten the plastic bottles, which is more conducive to the crushing roller. At the same time, after the crushing is completed, the crushed materials are screened by the screen. The materials that meet the crushing requirements will pass through the screen and enter the material transport vehicle; while the materials that do not meet the requirements are intercepted on the screen. The sealed door is opened and the intercepted materials can be collected and recycled. Therefore, by screening the crushed materials, it is prevented that larger unprocessed plastic waste pieces are also recycled together, which is more conducive to the subsequent plastic recycling process. However, in the process of realizing the utility model, the inventor discovered that the prior art had the following problems: during use, the above-mentioned plastic bottle garbage crusher uses a screen to screen the crushed plastic fragments and particles, and the plastic particles that meet the particle size requirements pass through the screen and fall into the material transport cart. As for the plastic fragments with larger particle sizes that are difficult to pass through the screen, they will continue to accumulate on the surface of the screen, requiring the operator to actively open the sealing door to remove them, which is cumbersome to operate. In addition, during the crushing process, the large-particle plastic fragments accumulated on the surface of the screen will reduce the passability of the screen and hinder the normal discharge of small-particle plastic fragments, thereby affecting the crushing operation progress of the entire crusher.

[0004] In view of this, the utility model proposes a plastic bottle garbage crusher. Utility Model Content

[0015] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0016] The utility model feeds the recycled plastic bottles after sorting through a conveyor belt inside a feed pipe, and the plastic bottles fall into between two crushing rollers to realize crushing processing operation. By setting a screening net, the plastic fragments that meet the particle size requirements after crushing pass through the screening net and fall into the aggregate frame, while those that do not meet the particle size requirements will slide to the right along the screening net and enter the return pipe. Under the driving action of the servo motor, the feeding auger blades re-input the plastic fragments that do not meet the particle size requirements into the feed pipe, and then use the crushing rollers to crush the plastic fragments again until the plastic fragments can pass through the screening net. With this processing method, the operator does not need to clean the surface of the screening net additionally, and the operation is simple. Moreover, since large-volume plastic fragments slide on the surface of the screening net and will not accumulate on the surface of the screening net, they will not hinder the discharge of small-size plastic fragments, thereby ensuring that the crusher can operate normally.

[0017] The utility model discloses that when recycled plastic is fed from a feed pipe, the extrusion roller is driven to rotate by a driving motor, so that the plastic bottle can be initially extruded. During the extrusion process, the pricking needle can pierce the plastic bottle, which is convenient for the subsequent crushing of the plastic bottle by a crushing roller. When the plastic fragments are located on the surface of the screening net, under the action of the limit slide bar and the connecting block, the screening net is movably installed inside the crushing box, and the crankshaft is driven to rotate by the rotation of the servo motor, which can drive the transmission rod to swing, so that the screening net is vibrated, and the mobility of the plastic fragments is improved, thereby improving the screening effect of the screening net on the plastic fragments, and facilitating the plastic fragments with larger particle sizes to slide into the inside of the return pipe. By arranging a longitudinal baffle on the surface of the screening net, the plastic fragments can be blocked, and the speed at which the plastic fragments slide down on the surface of the screening net can be slowed down, so as to prevent the small particle size fragments that meet the screening requirements of the screening net from sliding into the return pipe quickly, thereby ensuring that the small particle size fragments can be discharged normally.

A screen outlet 8 is opened on the right side wall of the crushing box 1 corresponding to the lower end of the screening net 5. The screen outlet 8 is connected to the return material pipe 7. The top of the return material pipe 7 is connected to the feed pipe 2. A servo motor 9 is fixedly installed on the right side of the crushing box 1. The output shaft of the servo motor 9 extends to the interior of the return material pipe 7 and is fixedly installed with a feeding auger blade 10.

[0030] By setting up a return material component, the plastic fragments that do not meet the particle size requirements after crushing will slide to the right along the screening net 5 and enter the return material pipe 7. Under the drive of the servo motor 9, the feeding auger blade 10 will re-input the plastic fragments that do not meet the particle size requirements into the feed pipe 2, and then the crushing roller 4 will be used to crush the plastic fragments again, and the cycle will be repeated until the plastic fragments can pass through the screening net 5.
