Description

Technical Field

[0001] This utility model relates to the field of crushing device technology, specifically a waste plastic recycling crushing device. Background Technology

[0002] Waste plastic recycling and crushing equipment is a specialized device used to recycle and crush waste plastics into small pieces or granules. Waste plastics enter the crushing chamber through the feed inlet, where they are cut, torn, and compressed under the high-speed rotation of the motor-driven blades, gradually breaking them into smaller fragments.

[0003] Utility model patent CN216372941U discloses a crushing mechanism for recycling waste plastics, including a U-shaped base, an outer casing fixed to the top of the U-shaped base, a crushing box fixed to the top of the outer casing, a feeding funnel fixed to the top of the crushing box, a crushing roller assembly inside the crushing box, and a first crushing mechanism connected to the bottom of the crushing box via a pipe. By setting the crushing roller assembly, the crushing roller assembly can pre-crush the plastic, which not only improves the crushing effect but also prevents the plastic from clogging the first and second crushing mechanisms. By setting the first and second crushing mechanisms, the plastic can be crushed multiple times, resulting in high crushing efficiency and good crushing effect. By setting a collection box, the crushed plastic can be directly collected, making plastic collection convenient and facilitating the crushing operation.

[0004] In existing technologies, during the use of crushing devices, when waste plastics are added to the device, due to the varying sizes, shapes, and volumes of the waste plastics, they easily clog the feed inlet, affecting subsequent crushing operations. Furthermore, dust and particulate matter from the waste plastics can be dispersed into the air during crushing, causing pollution to the external environment. Therefore, improvements are needed. Utility Model Content

[0005] The purpose of this utility model is to provide a waste plastic recycling and crushing device, which solves the problem that waste plastic is easily blocked at the feed inlet during crushing, and also solves the problem that dust particles generated during crushing can easily cause pollution to the external environment.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a waste plastic recycling and crushing device, comprising a cabinet, a plurality of evenly distributed support rods fixedly connected to the lower end of the cabinet, a feeding port fixedly connected to the bottom of the cabinet, a box fixedly connected to the top of the cabinet, a feeding port fixedly connected to the top of the box, two symmetrically distributed drive motors fixedly installed on the right end of the cabinet, the output ends of the drive motors being rotatably connected to the cabinet, a crushing roller fixedly connected to the left end of the output end of the drive motors being rotatably connected to the cabinet, a fixed box fixedly connected to the left end of the cabinet, a feeding mechanism being provided on the box, and a dust collection mechanism being provided on the fixed box.

A rotary motor is fixedly installed at the right end of the housing, and the output end of the rotary motor is rotatably connected to the housing and fixedly connected to the rotating shaft. By designing this feeding mechanism, materials can be pushed into the cabinet to avoid blockage.

[0009] Preferably, a guide rod is fixedly connected to the outer side of the push rod, and the guide rod is slidably connected to the housing. By designing the guide rod, the movement of the push rod can be guided.

[0010] Preferably, the dust collection mechanism includes an air pump, which is fixedly installed on the bottom inner wall of the fixed box. An air inlet is located at the right end of the air pump. A filter plate is slidably connected inside the fixed box. A connecting pipe is fixedly connected to the right end of the fixed box and to the cabinet. A fixed pipe is fixedly connected to the right end of the connecting pipe, and multiple evenly distributed air inlets are fixedly connected to the outside of the fixed pipe.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] 1. This utility model utilizes the design of a drive motor. The output of the drive motor can drive the crushing roller to rotate and crush the material. During crushing, the material is conveyed into the cabinet through the box. During the material conveying process, the output of the drive motor can drive the rotating shaft to rotate, which in turn can realize the rotation of the cam. The rotation of the cam can push the hinge rod to deflect, and the hinge rod can push the hinge seat to move back and forth in the vertical direction. This allows the push block to move up and down at the feed inlet, pushing the material into the cabinet and preventing material blockage from affecting the subsequent crushing work.

[0015] 2. This utility model utilizes the design of an air pump. The air pump can draw air into the fixed box through the air inlet, creating a negative pressure inside the fixed box. Then, it can draw air through the connecting pipe, causing fine particles and dust generated during the crushing process to be drawn into the fixed box along with the air through the air inlet. Under the action of the filter plate, the particulate impurities can be filtered, preventing the smoke and dust generated during the crushing process from spilling out and polluting the external environment.

[0023] Please see Figure 1 , Figure 2 , Figure 3 The feeding mechanism 8 includes a rotating shaft 81. Inside the housing 4, two symmetrically distributed rotating shafts 81 are rotatably connected via bearings. A cam 82 is fixedly connected to the outer side of the rotating shaft 81, and a hinge rod 83 is hinged to the inner side of the cam 82. A hinge seat 84 is hinged to the other end of the hinge rod 83. A push rod 85 is fixedly connected to the lower end of the hinge seat 84, and a push block 86 is fixedly connected to the bottom of the push rod 85. A guide rod 87 is fixedly connected to the outer side of the push rod 85 and is slidably connected to the housing 4. By designing the guide rod 87, the movement of the push rod 85 can be guided. A rotary motor 88 is fixedly installed at the right end of the housing 4.

By designing the feeding mechanism 8, materials can be pushed into the interior of the cabinet 1 to avoid blockage.

[0024] Please see Figure 1 , Figure 2 , Figure 4The dust collection mechanism 9 includes an air pump 91. The air pump 91 is fixedly installed on the bottom of the inner wall of the fixed box 11. An exhaust port 92 is provided at the lower end of the air pump 91. The exhaust port 92 is fixedly connected to the fixed box 11. By designing the exhaust port 92, the gas inside the fixed box 11 can be discharged. An air inlet 93 is provided at the right end of the air pump 91. A filter plate 94 is slidably connected inside the fixed box 11. A support sleeve 95 is slidably sleeved on the outside of the filter plate 94.

[0026] When materials are conveyed through the feed inlet 6, the output of the rotating motor 88 simultaneously drives the rotating shaft 81 to rotate. The rotating shaft 81 drives the cam 82 to rotate. The rotation of the cam 82 causes the hinge rod 83 to deflect.

[0027] During the crushing process, the air pump 91 operates simultaneously. The air pump 91 draws air into the fixed box 11 through the air inlet 93, creating a negative pressure inside the fixed box 11. Then, it draws air out through the connecting pipe 96, so that the fine particles and dust generated during the crushing process are drawn into the fixed box 11 along with the air through the air inlet 98. Under the action of the filter plate 94, the particulate impurities can be filtered and the impurities will be retained on the surface of the filter plate 94, while the gas is discharged through the exhaust port 92, preventing the smoke and dust generated during the crushing process from spilling out and polluting the external environment.
