Description

Technical Field

[0001] The utility model relates to the technical field of abrasive belts, in particular to an anti-clogging abrasive belt. Background Art

[0002] Conventional coated abrasive products are made using a continuous production method, using a continuous glue coating process and a continuous electrostatic sand planting process. The sand surface is flat and the gaps between abrasives are small. Since the entire surface is a grinding area, it is easy for grinding chips to clog the sand belt, causing the sand belt to be scrapped due to loss of grinding ability, causing great waste and losses to users. In order to solve the problem of waste chips clogging the sand surface, coated abrasive manufacturers generally use a sparse sand planting method to increase the gaps between sand grains to achieve the purpose of anti-clogging. Although this method can alleviate the problem of clogging on the sand surface of the sand belt, it cannot completely solve the problem. Since the gaps between the sand grains of the product are relatively large, it can only be used for manual grinding and cannot be used for high-speed mechanical grinding. Therefore, there is an urgent need for an anti-clogging sand belt to solve the above problems. Utility Model Content

[0024] As the instruction manual Figure 1As shown, the utility model provides an anti-clogging sanding belt, including a base layer 1 and an abrasive layer 2 bonded to the base layer 1, the abrasive layer 2 includes a plurality of abrasive strips distributed in sequence along the transverse direction, the abrasive strips include a plurality of abrasive units 21 distributed in sequence along the longitudinal direction, adjacent abrasive strips are spaced apart to form a first chip removal groove 23, two longitudinally adjacent abrasive units 21 are spaced apart to form a second chip removal groove 24, the longitudinal direction is parallel to the length direction of the base layer, and the abrasive units 21 are provided with chip accumulation holes 22. In this embodiment, the abrasive is bonded to the base layer 1 by an adhesive to form an abrasive layer 2. The length direction of the base layer 1 is the longitudinal direction, and the width direction of the base layer 1 is the transverse direction. The first debonding groove 23 is arranged in the longitudinal direction, and the second debonding groove 24 is arranged in the transverse direction. A plurality of abrasive strips are arranged along the length direction of the base layer 1. Each abrasive unit is arranged at intervals. A first debonding groove 23 is formed between adjacent abrasive strips. On each abrasive strip, a second debonding groove 24 connected to the adjacent first debonding groove 23 is formed between adjacent abrasive units 21. The first debonding grooves 23 are connected by a pair of The corresponding second chip removal groove 24 is connected to form a chip removal area of ​​the abrasive layer 2, and a chip accumulation hole 22 is provided on the abrasive unit 21, so that during the grinding process, the ground material on the abrasive unit 21 can be discharged into the first chip removal groove 23, the second chip removal groove 24 or the chip accumulation hole 22, which can effectively prevent the ground material from clogging the sand surface of the sanding belt and improve the grinding effect. The first chip removal groove 23 extends to the edge of the base layer 1, and / or the second chip removal groove 24 extends to the edge of the base layer 1, which is convenient for the discharge of the ground material. The ground material in the chip accumulation hole 22 can be thrown out when the workpiece leaves the sanding belt.

[0025] As one of the specific implementations, the first debonding groove 23 and the second debonding groove 24 may be grooves opened on the abrasive layer 2 , and the groove depths of the first debonding groove 23 and the second debonding groove 24 are less than the thickness of the abrasive unit 21 .

[0026] In this embodiment, intermittent glue coating and intermittent electrostatic sand implantation are adopted, and glue coating and sand implantation are performed only on the base layer 1 corresponding to the abrasive unit 21, and glue coating and sand implantation are not performed in the first debonding groove 23 and the second debonding groove 24 area, which can effectively reduce the use of glue and abrasive and save costs.

[0027] In an optimized implementation manner, the chip accumulation hole 22 is a blind hole or a through hole penetrating the base layer 1 .

[0028] Specifically, the chip hole 22 can be obtained in the following ways. First, the chip hole 22 can be a blind hole opened on the abrasive unit 21. Second, the chip hole 22 can be a hole formed at the corresponding position of the base layer 1 without glue coating and sand planting. Third, the chip hole 22 can be a through hole that penetrates the base layer 1. During the grinding process, the grind can be thrown out through the through hole.

[0029] In an optimized implementation manner, the chip accumulation hole 22 is arranged at the center of the abrasive unit 21 .

[0030] In an optimized implementation method, the groove width of the first chip removal groove 23 is greater than the groove width of the second chip removal groove 24, the first chip removal groove 23 serves as a main chip removal groove, and the second chip removal groove 24 serves as an auxiliary chip removal groove, and the auxiliary chip removal groove is connected to the main chip removal groove. Through the reasonable layout of the first chip removal groove 23 and the second chip removal groove 24, the area of ​​the abrasive unit can be effectively increased while ensuring the chip removal effect, thereby ensuring the grinding effect.

[0031] An optimized implementation method is that the abrasive layer 2 is made of a material with high thermal conductivity. Specifically, during the preparation of the abrasive layer 2, a certain amount of heat-dissipating and high-temperature resistant material is added to the abrasive, such as high-strength synthetic mineral sand, and the particle size of the mineral sand is equivalent to that of the abrasive. This can effectively improve the heat dissipation effect of the abrasive unit and avoid local problems that are too high during the grinding process, which will affect the product.

[0032] In an optimized implementation mode, the abrasive unit 21 is a hexagonal unit, preferably a regular hexagon. The abrasive units 21 in each abrasive strip are arranged side by side in sequence along the length direction of the base layer 1. Adjacent abrasive strips are staggered, and the second debonding grooves 24 between adjacent abrasive strips are staggered. Each abrasive unit 21 is honeycomb-shaped on the base layer 1. The abrasive unit 21 is a hexagonal unit with uniform shape and specifications, so that the sanding belt has better flexibility.

[0033] In an optimized implementation manner, adjacent sides of two adjacent abrasive units 21 are parallel to each other, and as many abrasive units 21 as possible can be arranged on the base layer 1 .

[0034] In an optimized implementation, the first chip removal grooves 23 formed between adjacent abrasive strips are in the shape of racks, so that the abrasive material can be better discharged from the chip removal grooves.

[0035] In an optimized implementation manner, the second debonding groove 24 is arranged along the width direction of the abrasive layer.

[0036] In an optimized implementation mode, the base layer 1 is a paper base layer, a cloth base layer, a polyester film base layer, a steel paper base layer or a sponge base layer, and the material of the base layer 1 can be selected according to actual needs.
