Description

Technical Field

[0001] The utility model relates to the technical field of plastic crushing, in particular to a plastic crushing device for processing packaging bottles. Background Art

[0002] Plastics are made of natural or synthetic resins as the main component, and then various additives are added. They are molded into a certain shape under certain conditions such as temperature and pressure. Generally speaking, the materials used to make plastics will keep their shape unchanged at room temperature. However, after plastic products are used for too long or damaged, many of them will become waste products and then be eliminated for re-production. General waste plastic crushing devices can only perform simple crushing on plastics. After crushing, the plastics cannot be cleaned, that is, the impurities in the plastics cannot be removed, and secondary processing is required, which is inconvenient to use.

[0003] Chinese patent CN218083671U discloses a waste plastic crushing device, which achieves the following beneficial effects: through the arrangement of a spiral conveying rod and a cleaning cylinder, after the cleaning cylinder receives the plastic crushed by the two crushing rollers, the plastic will move through the drive of the bolt conveying rod, and the plastic will repeatedly rotate up and down under the drive of the spiral conveying rod. During this process, the cleaning part cleans the plastic inside the cleaning cylinder; by arranging the spiral conveying rod with a left-handed part and a right-handed part, more plastic can be drained and the cleaning effect is good. However, the above device still has the following shortcomings in actual application:

[0004] 1. Since the cleaning cylinder cavity is a straight structure, a large amount of cleaning liquid entering can easily flow left and right during cleaning, causing a considerable amount of water to flow out through the material pipe to the material collection box, and the other part to flow into the waste liquid collection box, thus failing to achieve the desired solid-liquid separation effect and being unfavorable for the collection and classification of plastic fragments.

[0005] 2. In addition, the spiral conveyor rod will not frequently and effectively rotate and stir the plastic fragments when pushing them. It will only move forward along the bottom of the cleaning cylinder cavity in the pushing state. The spraying direction of the nozzle located directly above will not only be hindered by the spiral conveyor rod to a certain extent, affecting the all-round flushing of the fragments, but the sprayed liquid will only mainly flush the plastic fragments on the upper layer, and the plastic fragments accumulated below are difficult to be effectively flushed.

[0024] In order to make the purpose, technical solution and advantages of the present invention more clear, the implementation mode of the present invention will be further described in detail below with reference to the accompanying drawings.

[0025] Figure 1-Figure 4 The following is a schematic diagram of the entire structure of a plastic crushing device for packaging bottle processing according to the utility model. Figure 1-Figure 4 The present embodiment is a plastic crushing device for processing packaging bottles, comprising a crushing cabin 10, the top of the crushing cabin 10 is provided with a material guide port 101, a group of crushing rollers 102 located below the material guide port 101 are arranged inside the crushing cabin 10, a cleaning cylinder 20 is arranged below the crushing rollers 102, a feed port 201 of the cleaning cylinder 20 is located at the discharge end of the crushing rollers 102, a spiral conveying rod 202 is arranged inside the cleaning cylinder 20 along its length direction, the spiral conveying rod 202 is hollow inside, and the spiral conveying rod A middle section of 202 is provided with evenly distributed spray holes 202a, the cleaning cylinder 20 extends to the outer end of the crushing chamber 10 and is provided with a discharge pipe 203, an arc-shaped filter plate 21 is fitted and installed at the bottom of the cleaning cylinder 20, a rotating drive assembly 30 that can drive the spiral conveying rod 202 to rotate axially is provided on one side of the crushing chamber 10, a water conveying pipe 40 is rotatably installed on the inner side of one end of the spiral conveying rod 202 through a sealing shaft, and a waste liquid collection box 50 is provided inside the crushing chamber 10 and directly below the arc-shaped filter plate 21.

[0026] The arc filter plate 21 includes an arc plate 210 detachably mounted on the bottom of the cleaning cylinder 20, the inner arc surface of the arc plate 210 has a hollow card slot 210a, and the inner side of the hollow card slot 210a is matched with a filter screen 211. Here, by setting a section of arc filter plate 21 at the bottom of the cleaning cylinder 20, when the spray hole 202a flushes the plastic fragments, the water accumulated in the cylinder will immediately pass through the filter screen 211 and the hollow card slot 210a and be discharged to the waste liquid collection box 50. At the same time, the cleaned plastic fragments are continued to be pushed and discharged through the discharge pipe 203, thereby achieving the effect of solid-liquid separation, which is simple and practical.

[0027] The rotary drive assembly 30 includes a passive gear 301 fixed to the outside of the spiral conveying rod 202, a servo motor 302 arranged on the outside of the crushing chamber 10, and a main gear 303 fixed to the output shaft end of the servo motor 302 and meshing with the passive gear 301.

[0031] In summary, in the present embodiment, a plastic crushing device for processing packaging bottles is used. When in operation, clean water is injected into the water pipe 40 and the rotating spiral conveying rod 202 at high pressure through the water hose 401 and the pump group. When the plastic fragments are pushed forward in the cleaning barrel 20, the high-pressure water in the spiral conveying rod 202 will closely rinse, stir and roll the plastic fragments in the barrel through the spray hole 202a, so that the plastic fragments are fully cleaned in all directions. At the same time, the water accumulated in the barrel will immediately pass through the filter screen 211 and the hollow card slot 210a to be discharged to the waste liquid collection box 50. At the same time, the cleaned plastic fragments are continued to be pushed and discharged through the discharge pipe 203, thereby achieving the effect of solid-liquid separation.
