Description

Technical Field

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

[0002] In the field of plastic product processing, the polishing process is a crucial step in improving the surface quality, precision, and functionality of products. With the widespread application of plastic materials in industries such as automotive, electronics, and home furnishings, the requirements for the efficiency and quality of plastic part polishing are becoming increasingly stringent. Abrasive belts, as a commonly used processing tool, are widely used in plastic polishing due to their high-efficiency cutting capabilities and good adaptability.

[0003] Currently, when processing soft plastics such as PE, traditional plastic grinding equipment easily produces debris that adheres to the abrasive belt, causing blockage. This not only significantly reduces grinding efficiency but also affects grinding precision and shortens the belt's lifespan. Furthermore, existing cleaning methods either require machine shutdown, interrupting the production process and reducing processing efficiency, or rely on a single mechanical cleaning method that is insufficient to completely remove the sticky debris. In addition, most grinding equipment lacks the flexibility to adjust the grinding angle, making it difficult to meet the diverse grinding needs of complex-shaped plastic parts, resulting in poor processing adaptability.

[0004] Therefore, a plastic polishing device for processing plastic products is proposed to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a plastic grinding device for processing plastic products, which solves the problems of traditional grinding devices that require stopping the machine to clean the sanding belt and cannot flexibly adjust the grinding angle.

[0034] Example 2

[0035] In order to achieve flexible adjustment of the tension of the abrasive belt and stable operation of the abrasive belt 2, such as Figure 1 , Figure 2 and Figure 3 As shown, in this embodiment, the base 1 includes a base plate 11, on which a support frame 13 is mounted.

The drive motor 15 has the characteristic of stable power output, which can ensure the continuous and efficient operation of the sanding belt 2. The drive wheel 151 is connected to the drive motor 15 through a transmission connection, and the power is reliably transmitted to the sanding belt 2 through transmission components such as belts or chains.

[0039] Furthermore, the angle adjustment mechanism 3 is fixedly installed on the support frame 13, and the angle adjustment mechanism 3 is used to adjust the angle of the grinding end of the grinding belt 2;

[0040] The angle adjustment mechanism 3 includes a guide frame 31, a mounting frame 32 is mounted on the guide frame 31, and a driven wheel 33 is mounted on the mounting frame 32. There are two driven wheels 33, and the two driven wheels 33 are connected to the driving wheel 151 through the grinding belt 2.

[0041] Specifically, the angle adjustment mechanism 3, which is fixedly installed on the support frame 13, realizes the adjustment of the grinding end angle of the sanding belt 2. The angle adjustment mechanism 3 has the function of flexibly changing the grinding angle and can adapt to the diverse grinding needs of plastic parts of different shapes. The angle adjustment mechanism 3 includes a guide frame 31, a mounting frame 32 installed on the guide frame 31, and two driven wheels 33 installed on the mounting frame 32.

[0044] Example 3

[0045] To ensure a continuous supply of xylene solvent and uninterrupted cleaning of PE plastic residue on the surface of the abrasive belt, such as Figure 1 and Figure 4 As shown, in this embodiment, a placement box 12 is provided on the outside of the sponge block 4, and an elastic pressure plate is provided inside the placement box 12. The placement box 12 is fixedly installed on the base plate 11. A reserved groove 41 is opened on the sponge block 4 for adding xylene solvent. The sponge block 4 is in dynamic contact with the abrasive belt 2. A liquid level sensor is provided inside the placement box 12. When the xylene solvent is lower than the set liquid level, the sensor triggers an alarm to prompt the replenishment of solvent. The sponge block 4 is in dynamic contact with the abrasive belt 2 through the elastic pressure plate. The elastic pressure plate can adaptively adjust the contact pressure according to the rotation of the abrasive belt to ensure the cleaning effect.

[0046] Specifically, the placement box 12 on the outside of the sponge block 4 and the reserved groove 41 on the sponge block 4 enable the storage and replenishment of xylene solvent. The placement box 12 has the function of stably placing the sponge block 4 and storing solvent, which can ensure that the sponge block 4 is continuously immersed in solvent. The reserved groove 41 is opened on the sponge block 4, which makes it convenient and quick to add xylene solvent. In addition, the sponge block 4 and the sanding belt 2 are in dynamic contact, which cleans the PE plastic residue on the surface of the sanding belt in real time during the sanding process.

[0047] When using this utility model, confirm that the base plate 11 of the base 1 is placed firmly and that the support frame 13 is firmly connected to the base plate 11; check whether the sanding belt 2 is a polyester-based sanding belt and is free from damage or aging; check whether the sponge block 4 is installed in the placement box 12 and whether the xylene solvent in the reserved groove 41 is sufficient.

[0048] Rotate the adjusting screw of the tension adjustment component 14 to push the adjusting slider to slide along the support frame 13, so that the sanding belt 2 reaches the appropriate tension.

[0049] According to the shape of the plastic part to be processed, loosen the adjusting bolt 323 to allow the mounting bracket 32 ​​to rotate around the mounting bolt 322; adjust the mounting bracket 32 ​​to the target angle, and then tighten the adjusting bolt 323 to fix it.

[0050] Connect the power supply and start the drive motor 15. The drive wheel 151 drives the sanding belt 2 and the driven wheel 33 to rotate synchronously. Observe whether the sanding belt runs smoothly and without abnormal vibration or noise.

[0051] Hold the plastic part and gently press the surface to be sanded onto the sanding end of the sanding belt; move the plastic part at a constant speed, maintaining uniform contact pressure with the sanding belt, approximately 0.2-0.5 kg / cm². 2 This avoids excessive pressure that could clog the sanding belt. During the sanding process, sponge block 4 comes into dynamic contact with the sanding belt, and xylene solvent continuously dissolves and removes any PE plastic residue from the surface of the sanding belt.

[0052] Every 10-15 minutes of grinding, stop the machine and check the residue on the sanding belt surface. If the sponge block 4 absorbs a large amount of debris, it needs to be removed, cleaned, or replaced. Observe the degree of wear on the sanding belt. If the abrasive grains are severely detached or the sanding belt tension changes, adjust the tension adjustment component 14 or replace the sanding belt in time.

[0053] When the liquid level sensor in the placement box 12 issues an alarm, xylene solvent is added to the specified level through the reserved tank 41; when adding solvent, avoid spilling it into other parts of the equipment.

[0054] After grinding is complete, stop the drive motor 15 and wait for the sanding belt to stop rotating completely before disconnecting the power. Clean the plastic debris and solvent residue on the workbench, remove the sponge block 4, rinse it with clean water, and dry it before storing it to prevent the solvent from evaporating and leaving crystals. Regularly apply lubricating oil to the bolts and sliding parts of the tension adjustment component 14 and the angle adjustment mechanism 3 to keep them running smoothly.

[0055] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention.
