Production process and original opening correction process of spiral mesh

Abstract

The invention relates to a production process and an original opening correction process of a spiral mesh. The original opening correction process comprises the following steps: step A, disassembling: disassembling a spiral mesh B into a part A and a part B; step B, overturning: the part A and the part B are overturned respectively, so that the outer side ends of the part A and the part B are close to each other; c, splicing is conducted, specifically, the turned part A and the turned part B are spliced into a spiral mesh C, and it is guaranteed that no double rings exist in the splicing process; and in the spiral mesh B and the spiral mesh C, the spiral directions of the adjacent spiral wires are opposite. In the production process of the spiral mesh, the spiral mesh prepared after original opening correction is adopted, the original opening splicing operation is simple and easy to implement, and even if non-professional personnel do not adopt non-professional tools, it can be guaranteed that no double rings and no bumps exist in the original opening splicing process.

Description

technical field [0001] The invention belongs to the technical field of spiral mesh belt production, and particularly relates to a production process of a spiral mesh sheet and a raw-mouth calibration process. Background technique [0002] Spiral mesh is usually made of polyester plastic, which is widely used in conveying and filtering equipment as a conveyor belt or filter material; the purchaser of the spiral mesh will splicing the original openings at both ends of the spiral mesh. , forming as Figure 4 The annular structure shown is used; the current production process of the existing spiral mesh usually includes the following steps: step 1, preparing the polyester monofilament into a spiral wire, and step 2, splicing the spiral wire into a spiral mesh by using the monofilament. Belt, step 3, heating and shaping the spiral mesh belt, step 4, threading the filling wire, step 5, ironing and vulcanizing, step 6, disassembling the spiral mesh belt after ironing and vulcanizat...

Problems solved by technology

[0002] Spiral mesh is usually made of polyester plastic, which is widely used in conveying and filtering equipment, as a conveyor belt or filter material; when in use, the purchaser of the spiral mesh splices the original openings at both ends of the spiral mesh , formed as Figure 4 The ring structure shown is used; the production process of the existing spiral mesh usually includes the following steps: step 1, preparing polyester monofilament into spiral filament, step 2, splicing the spiral filament into spiral mesh with monofilament Belt, step 3, heating and shaping the spiral mesh belt, step 4, threading filling wire, step 5, ironing and vulcanizing, step 6, disassembling the spiral mesh belt after ironing and vulcanization into spiral mesh sheets of specified size, step 7 1. After the side edge sealing glue in the width direction of the spiral mesh is treated, it can be packaged; and the problem existing in this process is: the spiral mesh tends to tilt the side during the stretching process of heating and shaping, resulting in There are errors in the shape and size of the spiral mesh, which leads to the fact that the width of the original opening at both ends of the prepared spiral mesh cannot be guaranteed to be consistent. For this reason, the purchaser is splicing the original opening, and the spiral mesh is made of monofilament D27 When splicing into a circular spiral mesh belt, if it is necessary to ensure that there is no double ring in the original splicing, it will inevitably produce a bulge phenomenon, resulting in a serious deviation problem in the use of the circular spiral mesh belt, and this problem cannot be corrected; If there is no bulge, it can only be allowed to form a partial double ring during the splicing process of the original mouth. The double ring structure is as follows figure 1 As shown, there will be small holes around the double ring, which reduces the quality of the spiral mesh belt. For some customers with low requirements, it can be used at any time, but for foreign users, it is almost unacceptable to use more double rings. Spiral mesh belt seriously affects the sales volume and sales unit price of spiral mesh belt
