Description

Technical Field

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

[0002] Plastics need to be crushed during processing to improve the utilization rate of plastic raw materials and reduce production costs. Current plastic crushing devices mostly adopt single-stage crushing, which may result in incomplete crushing of plastics. In addition, the friction and shearing during crushing may cause the temperature to rise, leading to adhesion. To address these issues, the inventors propose a crushing device for plastic particle processing. Utility Model Content

[0003] In order to solve the problems of incomplete crushing and adhesion of plastics during the crushing process in current plastic crushing devices, the purpose of this utility model is to provide a crushing device for processing plastic granules.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: a crushing device for processing plastic granules, comprising a vertical cylinder, a conical cavity fixedly connected to the top surface of the vertical cylinder, a material box fixedly connected to the top surface of the conical cavity, a grinding roller provided at the output end of the material box, a crushing chamber provided inside the vertical cylinder, a filter hole provided through the bottom surface of the crushing chamber, a grinding disc rotatably connected inside the crushing chamber, a rotating shaft fixedly connected to the center of the bottom surface of the grinding disc, a cooling pipe threaded around the outer wall of the crushing chamber, a housing provided below the crushing chamber, a motor provided inside the housing, and the output shaft end of the motor fixedly connected to the bottom end of the rotating shaft.

[0005] Preferably, an inclined platform is fixedly connected to the inner wall of the material box, and the bottom of the grinding roller corresponds to the inclined platform. There are two grinding rollers, which are arranged in parallel and have serrated surfaces. The two grinding rollers rotate at the same speed but in opposite directions. The material box is used to store plastic raw materials. A drive box is provided on the side wall of the material box, which contains a driver and a gear set. Activating the driver causes the gear set to rotate, and the two grinding rollers can rotate in opposite directions through the gear set to perform preliminary coarse crushing on the material falling into the material box. The coarsely crushed material falls into the crushing chamber through a conical ring for further crushing. The grinding disc performs fine crushing. The outer wall of the vertical cylinder is fixedly connected with an inlet pipe connector and an outlet pipe connector. The output end of the inlet pipe connector is connected to the input end of the cooling pipe, and the input end of the outlet pipe connector is connected to the output end of the cooling pipe. An external water supply pipe is connected to the inlet pipe connector, and an external drain pipe is connected to the outlet pipe connector. Water is allowed to enter the cooling pipe through the inlet pipe connector to cool the crushing chamber and prevent the plastic particles from being subjected to friction and shearing during crushing, which could cause the temperature to rise and lead to adhesion. The used water is discharged into the external drain pipe through the outlet pipe connector.

[0006] Preferably, a conical ring is fixedly connected to the top surface of the crushing chamber. The conical ring is wider at the top and narrower at the bottom, and its outer wall is fixedly connected to the inner wall of the vertical cylinder. The conical ring is used to guide the material to be coarsely crushed into the crushing chamber. A conical platform is fixedly connected to the top surface of the grinding disc. The conical platform is used to prevent the coarsely crushed material from remaining on the grinding disc, so that the coarsely crushed material can slide into the crushing chamber for fine crushing by the grinding disc. A base is provided on the side wall of the motor. The base is fixedly connected to the inner wall of the housing. A support plate is fixedly connected to the bottom surface of the housing. An air hole is provided through the center of the bottom surface of the support plate. The opening of the housing corresponds to the air hole. The outer wall of the support plate is fixedly connected to the inner wall of the vertical cylinder. A horizontal plate is fixedly connected to the vertical cylinder, with the side of the horizontal plate away from the support plate fixedly connected to the inner wall of the vertical cylinder. A vertical plate is fixedly connected to the top surface of the horizontal plate, and the top surface of the vertical plate is fixedly connected to the outer wall of the crushing chamber. The motor is installed through a base, and the shell opening corresponds to the air hole to dissipate heat from the motor. When the motor is started, the rotating shaft can drive the grinding disc to rotate under the action of the motor output shaft, so as to finely crush the coarse material located in the crushing chamber. A discharge port is provided through the top surface of the vertical cylinder, and the finely crushed material can fall through the filter hole and leave the vertical cylinder through the discharge port for centralized processing. Support legs are fixedly connected to the side wall of the vertical cylinder, and an end cover is detachably provided on the top surface of the material box.

[0007] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0008] 1. This utility model has a good crushing effect and can crush materials in a step-like manner. The set grinding rollers can rotate in opposite directions, so as to initially crush the materials falling in the material box. Then, through the cooperation of the grinding disc and the crushing chamber, the coarsely crushed materials can be sheared and ground a second time to achieve fine crushing. The finely crushed materials can fall through the filter holes and the discharge port for centralized processing.

[0009] 2. In this utility model, the crushing chamber can be cooled down during the crushing process to avoid the plastic particles being subjected to friction and shearing during crushing, which would cause the temperature to rise and thus cause adhesion, thereby avoiding affecting the crushing effect.
