Description

Technical Field

[0001] The invention relates to the technical field of grinding wheel preparation, in particular to an automatic resin grinding wheel forming machine. Background Art

[0002] Grinding wheel is also called bonded abrasive. It is a bonded abrasive with a certain strength that is formed by bonding ordinary abrasive into a certain shape (mostly round with a through hole in the center). It is generally composed of abrasive, bonding agent and pores, which are often called the three elements of bonded abrasive. According to the different classifications of bonding agents, the common ones are ceramic (bond) grinding wheel, resin (bond) grinding wheel and rubber (bond) grinding wheel. Grinding wheel is the most widely used and widely used abrasive tool. It rotates at high speed when used, and can be used for rough grinding, semi-finishing grinding and fine grinding of the outer circle, inner circle, plane and various profiles of metal or non-metal workpieces, as well as grooving and cutting. Grinding wheel is the most important type of abrasive tool in grinding. Grinding wheel is a porous body made by adding bonding agent to abrasive, pressing, drying and roasting. Due to the different abrasives, bonding agents and manufacturing processes, the characteristics of grinding wheels vary greatly, which has an important impact on the processing quality, productivity and economy of grinding. The characteristics of the grinding wheel are mainly determined by factors such as abrasive, grain size, binder, hardness, structure, shape and size.

[0003] For resin grinding wheels, the production process of resin grinding wheels can be divided into three stages: molding, curing and dressing. Among them, the molding stage is the core process, and its process quality often determines the quality of the final product. Common problems in the molding stage include: 1. Unstable feeding, resulting in different thicknesses of the produced grinding wheels; 2. Uneven mixing of raw materials, easy to produce lumps, and there are no measures to deal with lumps in the feeding process, which easily leads to defective products; 3. It is inconvenient to take materials after molding, which is easy to damage the produced molded grinding wheels.

[0004] The patent with the publication number CN115592875B discloses a resin grinding wheel hot pressing molding device and a molding method. In the technical scheme disclosed in the patent, it includes: a PLC controller fixed on the front side of the resin grinding wheel hot pressing molding machine, which can control the start and stop of the device by using the PLC controller, guide rods fixed on the front and rear sides of the bottom of the inner cavity of the resin grinding wheel hot pressing molding machine, which can support and guide the loading table by using the guide rods, an air inlet opened on the left side of the resin grinding wheel hot pressing molding machine, and a fan fixed in the middle of the top of the resin grinding wheel hot pressing molding machine. The invention can prevent uneven paving, thereby avoiding the situation that the resin grinding wheel finished product is thinner on the inside and thicker on the outside, improving product quality, and the demoulding process is more convenient, and the tail gas generated by the heating of the resin can be effectively collected and treated for discharge, thereby preventing the staff from inhaling it for a long time and causing damage to their health. It is easy to use, has low manufacturing and maintenance costs, and has good application prospects. However, in the technical solution disclosed in the patent, the scraper is used to level the raw materials. After the equipment has been working for a long time, the scraper is prone to heat up and cause adhesion to the raw materials, which has certain limitations. The patent also uses iron demolding columns to demold the grinding wheel. The demolding structure of the iron material is prone to cause wear to the grinding wheel. At the same time, the production efficiency of the patented equipment is low, and it also has certain limitations for industrial mass production.

[0005] In view of this, we propose an automatic resin grinding wheel forming machine, which uses vertical and horizontal dual rotating blades to crush the lumps that may exist in the raw materials to avoid the influence of raw material agglomeration on the forming of the grinding wheel. At the same time, the present invention also uses the periodic mold transportation of the conveyor belt and the periodic pressing process of the rotating hot pressing roller and the cylinder assembly to improve production efficiency. In addition, the present invention also uses a vacuum suction roller to adsorb the elastic forming mold to assist in the demolding operation.
