Description

Technical Field

[0001] This utility model relates to the field of thermoforming countertop production technology, and more specifically, to a plastic board grinding and polishing equipment for thermoforming countertop production. Background Technology

[0002] In the production process of vacuum-formed countertops, the grinding and polishing of the plastic sheets is a crucial step, directly affecting the surface quality, smoothness, and the final product's aesthetics and practicality. However, existing plastic sheet grinding and polishing equipment has many problems, severely restricting the improvement of production efficiency and product quality.

[0003] Traditional manual grinding and polishing equipment often uses simple and fixed methods to fix plastic sheets. Commonly, fixed-size clamps or slots are used, but this method can only accommodate plastic sheets of specific sizes and shapes. When dealing with plastic sheets of different specifications, especially irregular shapes, it is necessary to change the appropriate clamps, which is cumbersome and time-consuming, significantly reducing production efficiency. Moreover, this fixing method makes it difficult to ensure the stability of the plastic sheet during grinding, easily leading to shaking or displacement, resulting in uneven grinding and affecting product quality.

[0004] Furthermore, manual polishing generates a large amount of dust. This dust not only permeates the working environment, posing a health hazard to operators and potentially causing respiratory illnesses with prolonged inhalation, but also adheres to the surface of plastic sheets, affecting the polishing effect and reducing product yield. Although some traditional equipment is equipped with simple dust removal devices, the dust removal effect is not ideal and cannot effectively and promptly remove the dust. Utility Model Content

[0005] Based on the above-mentioned technical problems, this utility model proposes a plastic board grinding and polishing equipment for the production of vacuum forming countertops.

[0008] The limiting and fixing mechanism includes a slide groove set on the worktable and multiple limiting units set in the slide groove. The slide groove is a grid-shaped T-shaped groove. The limiting units are slidably installed in the slide groove. The limiting units are provided with long nuts, which can fix the limiting units at any point in the slide groove.

[0009] Furthermore, the limiting unit consists of a base, a stud, and a long nut adapted to the stud. The base is located at the bottom of the slide groove, the lower end of the stud is fixed on the base, the upper end of the stud extends above the slide groove, and the long nut is assembled onto the stud.

[0010] Furthermore, the outer diameter of the long nut is greater than the width of the groove.

[0011] Furthermore, the long nut is provided with a flexible sleeve on its exterior.

[0012] Furthermore, the cross intersection of the groove is provided with an arc transition structure.

[0013] Furthermore, the height of the long nut is lower than the height of the plate.

[0014] Beneficial effects:

[0015] 1. Flexible and stable fixing: The grid-like T-slot slide and the adjustable limiting unit can adapt to plastic plates of different sizes and shapes, so as to achieve a firm fixation of the plastic plates, effectively avoid the shaking and displacement of the plastic plates during the sanding process, and improve the sanding quality.

[0016] 2. High-efficiency dust handling: The negative pressure structure can promptly remove dust generated during grinding, improve the working environment, protect the health of operators, and at the same time, the adsorption effect on the plastic board further enhances the fixing effect and improves the product yield.

[0017] 3. Easy to operate: The design of the limiting unit allows operators to easily adjust its position and fix it. The flexible sleeve outside the long nut facilitates operation, and the arc transition structure of the slide groove makes the limiting unit slide smoothly.

Detailed Implementation

[0023] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0024] like Figs. 1-3 The image shows a plastic board grinding and polishing equipment for producing vacuum forming tabletops. This equipment mainly consists of two parts: a worktable 1 and a limiting and fixing mechanism.

[0025] Workbench 1:

[0026] The workbench 1 has multiple upward-supporting legs 2 on its underside, providing stable support for the entire device. The workbench 1 has an array of through holes 5, which are connected to the negative pressure box 3 on the underside of the workbench 1. The negative pressure box 3 is connected to the negative pressure equipment through a negative pressure pipe 4. When the negative pressure equipment is started, a negative pressure environment is formed on the surface of the workbench 1. On the one hand, this negative pressure structure can remove the dust generated during the grinding process in a timely manner, effectively improving the working environment and protecting the health of the operators. On the other hand, it can also have a certain adsorption effect on the plastic board placed on the workbench 1, enhancing the stability of the plastic board during the grinding process.

[0027] Limiting and fixing mechanism: The limiting and fixing mechanism includes a slide 6 set on the worktable 1 and multiple limiting units 7 set in the slide 6. The slide 6 is designed as a grid-like T-shaped structure. The unique shape and layout of the T-slot allows the limiting unit 7 to slide flexibly within the slide groove 6, facilitating position adjustment according to the size and shape of the plastic sheet. The limiting unit 7 consists of a base 701, a stud 702, and a long nut 703 that fits the stud 702. The base 701 is located at the bottom of the slide groove 6, providing support and positioning for the entire limiting unit 7. The base 701 can be configured as a square slide block, matching the lower part of the T-slot, so that the base 701 can only slide within the slide groove 6 and cannot rotate. The lower end of the stud 702 is fixed to the base 701, and its upper end extends above the slide groove 6. The long nut 703 is assembled onto the stud 702. By rotating the long nut 703, the limiting unit 7 can be fixed at any position in the slide groove 6. Before grinding, the operator can move the nearby limiting units 7 to various sides of the plastic sheet and firmly fix them to ensure that the plastic sheet will not shake or shift during grinding.

[0028] Detailed design of the limiting unit 7: The outer diameter of the long nut 703 is larger than the width of the slide groove 6. This ensures that when the long nut 703 is tightened, it can be firmly pressed against the edge of the slide groove 6, preventing the limiting unit 7 from accidentally sliding during use and enhancing the stability of the fixation. The long nut 703 is provided with a flexible sleeve 704 for fixed connection. This not only facilitates the operator to manually rotate the long nut 703, but also provides a certain degree of anti-slip effect and reduces damage to the side of the workpiece. The cross intersection of the slide groove 6 has an arc transition structure. This design makes the limiting unit 7 slide more smoothly in the slide groove 6, reducing jamming and improving the convenience of operation. The height of the long nut 703 is lower than the height of the board. This ensures that the long nut 703 will not interfere with the grinding operation when fixing the plastic board, ensuring the smooth progress of the grinding work.

[0029] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
