Description

   Method for manufacturing grid gauze with open holes   

The invention relates to a method for manufacturing a mesh gauze with open holes, in particular to a method for manufacturing a mesh gauze with large holes and providing good chip removal effect.

According to the general abrasive cloth, it is mainly used for the function of grinding and flattening the workpiece. Most of the abrasive gauze has a layer of gold-steel abrasive on one side and an attached terry layer on the other side. The abrasive layer is used to polish the surface of the workpiece. The terry layer is adhered to the rotating shaft of a grinder or a grinding machine. According to the manufacturing method, there are probably the following types:

(1) One-piece grinding gauze: mainly take one gauze, which has a loop layer and a plane layer. After coating the plane material with a glue material, the steel grit is gelled to form an integrated grinding gauze.

(2) Two-stage forming and grinding gauze: mainly take a gauze and a terry cloth. First, the gauze and the terry cloth are glued together through a glue to form a grinding abrasive cloth blank, and then placed on a mold for sandblasting. Two sections of shaped abrasive gauze.

However, the above two abrasive abrasive cloths actually have the following disadvantages:

(a) The disadvantages of the integrally formed abrasive cloth are (Note): the first disadvantage is that the loop layer and the plane layer are integrally formed, in other words, the plane layer is knitted first, and then the loop layer and the plane layer are stitched together, or The gauze in the plane layer has a warp and a weft on one side and a terry layer on the other side. The warp and weft are interwoven. It can be understood that this method is quite complicated and troublesome, and the defect rate is high. The second disadvantage is that the stage of gelling gold sand is because the entire abrasive cloth is put into the mold for sandblasting. It can be understood that the terry layer will touch the glue and cause the gold steel sand to adhere, making the terry layer adhere. poor effect. The third disadvantage is that the loop layer and the plane layer are too tightly combined. This design will cause the hole formed by the plane layer to be blocked by the wire of the loop layer during the grinding operation, which greatly reduces the chip removal effect.

(b) Two-section shaped abrasive gauze (Note): The first disadvantage is that when the gauze and the terry cloth are reattached, the terry layer is likely to stick to the glue and the terry cloth has poor adhesion. The second disadvantage is that since the gauze is sprayed with gauze, it can be understood that there will be a problem that the grit adheres to the terry cloth and causes clogging. The third disadvantage is that the steel grit is fully sprayed on the gauze so that the steel grit does not have a height difference. When regrinding, all the chips generated by the grinding are squeezed into the holes of the gauze, which greatly reduces the grinding effect.

The main object of the present invention is to provide a method for manufacturing a mesh gauze with open holes. When the steel grit is implanted, the steel grit layer on the weft is removed through a mold, so that the gold grit gauze has large holes and good drainage. Crumb effect.

The manufacturing method that can achieve the above purpose mainly includes: a sand-planting step: taking a straight yarn, and forming a square mesh structure composed of warp and weft yarns on the straight yarn; then coating the straight yarn with rubber material, and then blasting gold The steel grit forms a steel grit layer, and the other side is a flat gauze layer; a sand removal step: the steel grit layer attached to the weft is removed through a mold, leaving the steel grit layer on the warp yarn to form a grit gauze, and Gold steel gauze is rolled up in a roll and has a gold steel sand layer side facing inward; a terry layer preparation step: take a terry gauze that corresponds to the size of the first straight yarn, one side of the terry gauze is the surface The flat plain weave layer, on the other side, has more than one terry layer with adhesive effect, which is rolled up on a roller with the terry layer facing outwards; a laminating step (Note): the roll and the roller are separately It is placed on the adhesive molding machine, and the front ends of the golden steel gauze and the terry gauze are respectively combined on a forming roller. Furthermore, a rubber material tank is provided on the roller side of the adhesive molding machine, so that when the adhesive molding machine is started, Plain weave of terry gauze The gauze layer with the gluing layer of the alloy steel gauze is formed to form a grid gauze blank; a flattening step: the adhesive molding machine is provided with a flattening wheel, and the grid gauze blank is pressed and formed by the flattening wheel. The open mesh gauze is rolled up on a forming roller.

Through the above manufacturing methods, the advantages and effects obtainable by the present invention are briefly described as follows:

1. Through the mesh gauze with open holes manufactured by the present invention, the gold and steel sand layer on the weft is removed through the mold, so that the mesh distance of the mesh gauze is large, and the chip removal effect is good.

2. Due to the removal of the gold and steel sand layer on the weft, the mesh gauze with open holes has a high and low drop. The chips can be eliminated through the side of the weft to avoid accumulation, and the grinding effect and service life are improved.

3. Firstly plant the steel grit in the planting yarn to form the diamond gauze, and then combine the diamond gauze with the loop gauze through the adhesive molding machine to improve the process yield.

4. In the paste industry, the square grid of gold steel gauze corresponds to the hexagonal lattice of terry gauze. The gauze holes are open, and it is not easy to be blocked by chips, and the terry layer is not easy to pile up Good adhesion.
