Description

Technical Field

[0001] This utility model relates to the field of grinding equipment, specifically a grinding device for plastic parts. Background Technology

[0002] Plastic parts are a general term for daily necessities and industrial products made primarily from plastic. They include all products manufactured using processes such as injection molding and vacuum forming. When plastic products are fully formed, they need to be ground into the required shape using a grinding machine. When using a plastic grinding machine, the high-speed operation of the machine processes the plastic parts, generating high temperatures that can easily damage the plastic parts.

[0003] Referring to the existing patent document CN221248185U, a plastic parts grinding device includes a plastic grinding machine body, a dust suppression mechanism on one side of the plastic grinding machine body, a dust cover fixedly installed on the top of the plastic grinding machine body, a dust collection box movably connected to one side of the plastic grinding machine body, and a water tank including the dust suppression mechanism, which is fixedly connected to one side of the plastic grinding machine body. In use, this technical solution, by setting up the dust suppression mechanism, can effectively block plastic debris splashed during grinding of plastic parts by the dust cover. However, although this solution achieves dust suppression, it cannot cool the grinding equipment, which is inconvenient during use. Utility Model Content

[0004] In order to address the problem of cooling down a plastic parts grinding device disclosed in patent document CN221248185U during use, this application provides a plastic parts grinding device.

[0006] Through the above technical solution, the limiting roller and the support roller work together to provide limiting support for the grinding belt. Later, the tilt angle and tension of the grinding belt can be adjusted by moving the limiting roller and the support roller. The grinding of plastic parts with different shapes can be achieved by adjusting the tilt of the grinding belt.

[0007] Furthermore, a displacement mechanism is fixedly installed on the connecting seat, and a movable column is installed on the displacement mechanism. The limiting roller is installed on the movable column through the rotating column.

[0008] With the above technical solution, the displacement mechanism is an electric push rod, which pushes the push mechanism to move back and forth, thereby controlling the starting position of the support roller through the displacement mechanism.

[0009] Furthermore, a fixed rod is welded to one end of the movable column, a pushing mechanism is fixedly installed on the fixed rod, a fixed column is installed on the pushing mechanism, and the fixed column is connected to the support roller.

[0010] With the above technical solution, the driving mechanism is an electric push rod, which drives the support roller to move independently, and the movement of the support roller adjusts the tilt angle of the grinding belt.

[0011] Furthermore, a water inlet pipe is fixedly installed on the housing, and a motor housing is fixedly installed inside the housing. A water pump is installed inside the motor housing, and the water pump is installed inside the motor housing via a ring seat.

[0012] Through the above technical solution, the water pump pressurizes the water inside the tank and sprays it out from the spray nozzles on the water spray pipe. The sprayed water cools the grinding belt and washes and cleans the surface of the grinding belt at the same time.

[0013] Furthermore, an air inlet is provided on the side of the housing, and the air inlet is connected to the motor housing. A water pump is fixedly installed with a water suction pipe and a water spray pipe, and the water spray pipe has water spray holes.

[0014] Through the above technical solution, the air intake allows airflow to enter and cool the water pump, providing the necessary working environment for the water pump.

[0015] Furthermore, the fixed base has an inclined groove, and a collection box is movably installed at the bottom of the fixed base.

[0016] Through the above technical solution, water and impurities on the grinding belt fall into the inside of the inclined groove. Under the impact of the water flow, the water carries the impurities into the collection box for water collection.

[0017] In summary, this application includes at least one of the following beneficial technical effects:

[0018] 1. When this application is used, the limiting roller and the support roller cooperate to provide limiting support for the grinding belt. Later, the tilt angle and tension of the grinding belt are adjusted by moving the limiting roller and the support roller. The grinding of plastic parts with different shapes can be achieved by adjusting the tilt of the grinding belt.

[0019] 2. The water pump of this application pressurizes the water inside the tank and sprays it out from the spray nozzles on the spray pipe. The sprayed water cools the grinding belt and washes and cleans the surface of the grinding belt. The washed water and impurities fall into the inside of the inclined groove. Under the impact of the water flow, the water carries the impurities into the collection box for collection. Attached Figure Description

The limiting roller 8 is installed on the movable column 17 through the rotating column. The displacement mechanism 5 is an electric push rod. The electric push rod pushes the pushing mechanism 19 to move back and forth, thereby controlling the starting position of the support roller 7 through the displacement mechanism 5.

[0028] join Figure 2 A fixed rod 18 is welded to one end of the movable column 17. A pushing mechanism 19 is fixedly installed on the fixed rod 18. A fixed column 20 is installed on the pushing mechanism 19. The fixed column 20 is connected to the support roller 7. The pushing mechanism 19 is an electric push rod. The electric push rod pushes the support roller 7 to move independently. The movement of the support roller 7 adjusts the tilt angle of the grinding belt 13.

[0029] join Figure 1 and Figure 3 A water inlet pipe 11 is fixedly installed on the housing 2. A motor housing 21 is fixedly installed inside the housing 2. A water pump 22 is installed inside the motor housing 21. The water pump 22 is installed inside the motor housing 21 through a ring seat 23. The water pump 22 pressurizes the water inside the housing 2 and sprays it out from the spray nozzle on the water spray pipe 15. The sprayed water cools the grinding belt 13 and washes and cleans the surface of the grinding belt 13 at the same time.

[0030] join Figure 1 and Figure 2 The side of the housing 2 has an air inlet 3, which is connected to the motor housing 21. The water pump 22 is fixedly equipped with a water suction pipe 24 and a water spray pipe 15. The water spray pipe 15 has a water spray hole.

[0031] join Figure 1 and Figure 3 The fixed base 1 has a sloping groove 14, and a collection box 16 is movably installed at the bottom of the fixed base 1. Water and impurities on the grinding belt 13 fall into the inside of the sloping groove 14. Under the impact of the water flow, the water carries the impurities into the collection box 16 for water collection.

[0032] The implementation principle of the plastic part grinding device in this application embodiment is as follows: First, the tilt angle of the grinding belt 13 is adjusted according to the shape of the plastic part to be ground. At the same time, the displacement mechanism 5 and the pushing mechanism 19 are activated. The pushing mechanism 19 and the displacement mechanism 5 drive the support roller 7 and the limiting roller 8 to move synchronously. The synchronous movement of the support roller 7 and the limiting roller 8 ensures that, when the diameter of the grinding belt 13 is inconvenient, the support roller 7, the limiting roller 8 and the pulley 12 provide a constant support point for the grinding belt 13. The movement of the support roller 7 and the limiting roller 8 adjusts the pulley. The inclination of the grinding belt 13 between 12 and the support roller 7 is adjusted so that different shaped plastic parts can be ground. During grinding, the plastic part is held and brought into contact with the surface of the grinding belt 13 for grinding. At the same time, the water pump 22 is started. The water pump 22 draws water from the inside of the tank 2, pressurizes it and sprays it upward from the inside of the spray pipe 15. The spray cools the entire grinding belt 13. Under the impact of the water flow, the water and impurities on the grinding belt 13 fall into the inside of the inclined groove 14. Under the impact of the water flow, the water carries the impurities to the inside of the collection box 16 for water collection.

[0033] The advantages of this embodiment are:

[0034] When this application is used, the limiting roller and the support roller work together to provide limiting support for the grinding belt. Later, the tilt angle and tension of the grinding belt can be adjusted by moving the limiting roller and the support roller. The grinding of plastic parts with different shapes can be achieved by adjusting the tilt of the grinding belt.

[0035] The water pump pressurizes the water inside the tank and sprays it out from the spray nozzles on the spray pipe. The sprayed water cools the grinding belt and washes and cleans the surface of the grinding belt. The washed water and impurities fall into the chute. Under the impact of the water flow, the impurities are carried by the water to the inside of the collection tank for collection.
