A kind of sponge grinding block production line and production method

Abstract

The invention provides a sponge grinding block production line. The sponge grinding block production line comprises an uncoiling device, a surface treatment device, a sand embedding device, a drying device and a sponge combination device which are sequentially arranged in the thin film operation direction. The invention further provides a sponge grinding block production method. The method adopts the above devices and includes the following steps of uncoiling, surface treatment, static sand embedding, drying and sponge combination. Continuous and automatic machining can be sequentially finished on the same production line, the occupied space is small, a specially-assigned person on duty is not needed in all the processes, therefore, the labor force is saved, the labor intensity is relieved, and the production efficiency is improved; a thin film is subjected to surface treatment through the production method, the surface of the thin film is rough, the adsorption capacity can be improved, and gluing is more uniform; and by means of a metal layer electroplated on the surface of the thin film, the strength of the thin film is improved, gluing and sand embedding are facilitated, and the product quality is further guaranteed.

Description

technical field [0001] The invention relates to the field of abrasive tool processing, in particular to a production line for manufacturing sponge abrasive blocks and a production method for sponge abrasive blocks using the production line. Background technique [0002] In modern industrial production, grinding and polishing technology has a wide range of applications. The common grinding tools are sandpaper, emery cloth, grinding wheel, etc. However, in the current industrial processing, the requirements for grinding and polishing effects are getting higher and higher. Traditional abrasive tools have It cannot meet the requirements of use, so better abrasive tools are needed. The sponge abrasive tool is a kind of abrasive tool with sponge as the base layer and sand material coating as the grinding surface. Because of the elasticity, flexibility and water absorption of the sponge itself, the sponge abrasive tool has excellent performance in curved surface grinding and wet gr...

Problems solved by technology

However, there are still some problems in the current production method of sponge abrasives. When bonding the sponge and sand during the production process, if the sponge is directly glued and the sand is covered on the surface of the sponge, the grinding surface will become hard and flexible. If the film is used as an intermediate, the sand material is first planted on the film, and then bonded to the sponge through the film, and the surface of the smooth and soft film will be unevenly glued, and the adhesion is not strong enough, making the sand easy to fall off , or the separation of the sand surface layer and the sponge, which is quite inconvenient in actual use;

[0003] The current production equipment for sponge grinding blocks generally includes a sand planting device and a drying device. The finished film is rolled into a roll, and finally the rolled film is transported to the sponge, and the film is re-rolled on the non-sanded side with adhesive, and then the film and the sponge are bonded together by manual operation, and then passed The cutting machine cuts the film to obtain the sponge grinding block. This production method occupies a lot of space in the workshop, and other auxiliary equipment such as the sand planting device, drying device, and the device for bonding the sand planted film and sponge are scattered. A large number of workers are required to operate on duty. The material is time-consuming and laborious in the process of circulation, and is easily deformed. The production efficiency is low, which increases the labor intensity of the workers and increases the production cost. The quality of the product cannot be guaranteed. In the face of large-scale demand Insufficient production capacity may also occur
