Description

Technical Field

[0001] The present application relates to the technical field of pipeline processing, and in particular to a PE pipeline grinding and polishing device. Background Art

[0002] During the production process of PE pipes, especially after cutting, the cuts may be uneven, which not only affects the appearance, but also the connection and performance of the pipes. Therefore, grinding and polishing are necessary post-processing steps. Early PE pipe grinding mainly relied on manual handheld grinding devices, which was inefficient and the grinding effect was greatly affected by the operator's skills, making it difficult to ensure consistency and standardization. In order to solve the shortcomings of manual grinding, devices specifically used for PE pipe grinding have appeared on the market. These devices can grind pipes more efficiently and evenly, improving production efficiency and product quality.

[0003] In the related art, reference can be made to the Chinese utility model patent with authorization announcement number CN215510515U, which discloses a small-diameter PE pipe attached inner wall polishing device, including a base, a polishing mechanism is provided on one side of the base, and a fixing mechanism is provided on the other side of the base. The polishing mechanism includes a linear guide rail 1, a linear guide rail 2 is vertically provided on the slide of the linear guide rail 1, a motor is provided on the slide of the linear guide rail 2, the actuator shaft of the motor is arranged toward the fixing mechanism and an adjustable grinding head is provided at the end of the actuator shaft.

[0004] When the above-mentioned polishing device is polishing and grinding the PE pipe, a large amount of heat will be generated during the polishing work, and the high temperature resistance of the PE pipe is poor. Therefore, a considerable part of the debris ground off the PE pipe is softened PE pipe debris. These softened PE pipe debris will directly adhere to the working environment and are difficult to clean with a conventional vacuum cleaner. They need to be manually removed, which makes cleaning difficult and requires high work intensity. Utility Model Content

[0005] In order to reduce the probability of softened PE pipe debris adhering to the working environment, the present application provides a PE pipe grinding and polishing device.

[0006] The present application provides a PE pipe grinding and polishing device, which adopts the following technical solution:

[0007] A PE pipe grinding and polishing device comprises a frame and a grinding head arranged on the frame, the PE pipe is placed on the frame and then polished by the grinding head, the frame is provided with a cooling mechanism for cooling the PE pipe during polishing, the cooling mechanism comprises:

[0008] A cooling water pipe, wherein the cooling water pipe is arranged on the frame, one end of the cooling water pipe is connected to a water source, and the opening of the other end of the cooling water pipe is arranged toward the position where the grinding head grinds the PE pipe;

[0009] A water receiving trough, which is arranged on the frame and below the grinding head, and receives the water flowing down from the PE pipe;

[0010] A water return assembly is arranged on the frame and is used to recycle the water received by the water tank.

[0011] By adopting the above technical solution, when the grinding head grinds the PE pipe, water is passed through the cooling water pipe to spray water to cool the PE pipe and the grinding part of the grinding head. The water sprayed from the cooling water pipe cools the temperature of the grinding part of the PE pipe, and the grinding debris is also washed into the water receiving tank along with the water. The water receiving tank receives the water and the debris, and the excess water is reused through the return water component, so that the debris is processed while the cooling work of the PE pipe is completed, thereby reducing the probability of debris scattering in the working environment and causing pollution to the working environment.

[0012] Optionally, the water return component includes:

[0013] A return water tank, wherein the return water tank is arranged on the frame;

[0014] A first water return pipe, one end of which is arranged at the bottom of the water receiving tank and communicated with the inside of the water receiving tank, and the other end of which is arranged at the top of the water return tank and communicated with the inside of the water return tank;

Since the density of PE pipe debris is relatively small, the PE pipe debris will float on the surface of the water in the return water tank. The return water pump can extract the lower layer of clear liquid at the bottom of the return water tank and guide it back to the cooling water pipe through the second return water pipe for reuse, thereby completing the water reuse work and reducing the waste of water resources.
