Description

Elastic improved abrasive belt

Technical Field

The utility model relates to a equipment of polishing, more specifically say, it relates to an elasticity improvement abrasive band.

Background

Sanding is an important process in the processing of the plate, and the surface of the plate is generally sanded by using an abrasive belt to remove concave-convex parts and burrs on the surface of the plate so that the plate has a flat surface. To comparatively leveling face originally, use ordinary abrasive band can fully sand whole face basically, but in actual production, often the face roughness that has some panel does not reach the requirement, can appear local sanding in the time of leading to the abrasive band sanding and can not reach or the insufficient condition of sanding. However, because the elasticity of the common abrasive belt is poor, that is, the deformation adapting capability to the concave and convex surfaces is poor, during polishing, the abrasive belt is easily erected at the concave part, so that the concave part cannot be polished and a non-key sanding area around the concave part is ground over a large area. For the wood grain board with patterns, the patterns on the surface are easy to be ground off, and the texture of the board is damaged. In order to avoid the problem that the common abrasive belt is easy to damage the non-key sanding area, more effective equipment or process methods are needed. The utility model discloses a utility model patent with publication number CN214869866U discloses a polyurethane finish-cast abrasive belt, which comprises a base cloth layer, a primer layer, an abrasive particle layer, a surface adhesive layer and a nano composite coating which are sequentially arranged from bottom to top, and corundum abrasive particles which penetrate through the abrasive particle layer, the surface adhesive layer and the nano composite coating, wherein a plurality of chip grooves which penetrate through the abrasive particle layer, the surface adhesive layer and the nano composite coating and are arranged in a criss-cross manner are arranged on the upper end surface of the abrasive belt, and the back surface of the base cloth layer is sequentially provided with the bottom adhesive layer and an isolation film layer; in the process of eliminating abrasion, the particles which are partially eliminated and abraded are discharged along a chip groove, so that the particles are prevented from being accumulated on the surface of the abrasive belt, and the use efficiency of the abrasive belt is improved. However, the utility model does not have the elasticity improvement, so that the non-key sanding area is easy to damage as mentioned above.

SUMMERY OF THE UTILITY MODEL

The elasticity of the ordinary abrasive belt is relatively poor, and excessive sanding is very easily caused during the use, the texture of the plate is damaged, and for overcoming the defect, the utility model provides an elasticity improvement abrasive belt which can fully ensure that the sanding is sufficient and can avoid excessive sanding.

The technical scheme of the utility model is that: an elastic modified abrasive belt comprises a belt base layer, an elastic reinforcing layer and abrasive particles, wherein the elastic reinforcing layer is attached to the belt base layer, and the abrasive particles are attached to the elastic reinforcing layer. Elasticity strengthening layer has good elasticity, and when contacting with panel, elasticity strengthening layer easily compresses, can warp through self and adapt to concave and convex better to with the sunken position of panel abundant contact, fully sand, and the sanding power is softer than in ordinary abrasive band relatively, is difficult for causing excessive sand light, and is less to the damage in non-sand light region. The utility model discloses be particularly useful for the sand light processing of the wood grain board that has higher requirement to the decorative pattern integrality.

Preferably, the elastic reinforcing layer is a nonwoven layer. The non-woven fabric layer can provide good elasticity, is easy to obtain and has low cost.

Alternatively, the elastic reinforcement layer is a rubber layer. The rubber layer may also provide good elasticity.

Preferably, the elastic reinforcing layer is bonded to the tape base layer by a glue layer. The glue layer is used for bonding the scouring pad to the belt base layer, and the adhesion firmness of the elastic strengthening layer on the belt base layer is ensured.

Preferably, the tape base layer is a paper layer. The belt base layer is subjected to high centrifugal forces when the sanding belt is rotated at high speed on the sander and must therefore have a certain strength to ensure that it does not break. In addition, the base layer of the belt needs to have certain hardness, so that the abrasive belt has good stiffness and can be easily installed in a sander. Paper materials can meet the above requirements and are relatively economical.

Preferably, the abrasive particles are silicon carbide particles. Silicon carbide is the most widely used and economical abrasive.

Alternatively, the abrasive particles are alumina particles. The alumina abrasive particles have strong abrasive resistance and long service life.

The utility model has the advantages that:

the sanding is carried out more fully and comprehensively. The utility model discloses well elasticity strengthening layer has good elasticity, and when contacting with panel, elasticity strengthening layer easily compresses, can warp through self and adapt to the unsmooth face better to with the sunken position abundant contact of panel, fully polish sand light.

Preventing excessive sanding. The utility model discloses well elasticity strengthening layer has good elasticity, and the power of polishing is softer than ordinary abrasive band, is difficult for causing excessive sand light, and is less to the regional damage of non-sand light.

Drawings

FIG. 1 is a schematic view of the present invention;

fig. 2 is a schematic view of the usage state of the present invention.

In the figure, 1 is provided with a base layer, 2 is provided with an elastic reinforcing layer, 3 is provided with abrasive particles, 4 is provided with a plate material, 5 is provided with an upper adhesive layer and 6 is provided with a lower adhesive layer.

Detailed Description

The present invention will be further described with reference to the following specific embodiments in the drawings.

Example 1:

as shown in fig. 1 to 2, an elastic modified abrasive belt includes a belt base layer 1, an elastic reinforcing layer 2 and abrasive grains 3, wherein the elastic reinforcing layer 2 is attached on the belt base layer 1, and the abrasive grains 3 are attached on the elastic reinforcing layer 2 through an adhesive layer 5. The elastic strengthening layer 2 is a non-woven fabric layer. The elastic reinforcing layer 2 is bonded with the belt base layer 1 through the lower adhesive layer 6. The belt substrate 1 is a paper material. The abrasive grains 3 are silicon carbide grains.

Because the scouring pad has certain thickness and certain compression performance, when the scouring pad contacts with the plate 4, the scouring pad is compressed and thinned, the sand grains of the scouring pad contact with the plate surface, and a speed difference is formed between the abrasive belt and the plate surface when the abrasive belt rotates at a high speed, so that relative high-speed motion is generated, and the sanding effect is generated. Because the scouring pad has certain compressibility, when the board surface is not too flat, the sand grains on the scouring pad can also well contact with the whole board surface, the board surface can be fully sanded, and the phenomenon that the local part is not sanded can not be generated.

Example 2:

the elastic strengthening layer 2 is a rubber layer. The abrasive particles 3 are alumina particles. The rest is the same as example 1.
