The brake block is generally composed of a steel plate, a bonding heat insulation layer and a friction block, wherein the heat insulation layer is made of a non-heat-transfer material and aims to insulate heat; the friction block is composed of friction material and adhesive, and is extruded on the brake disc and the brake drum to generate friction during braking, so that the aim of decelerating and braking the vehicle is fulfilled. From the application object, the brake pads are divided into: brake pads for disc brakes, brake pads for drum brakes, brake pads for large trucks; from the composition of the friction material, brake pads are mainly classified into the following categories: asbestos brake blocks, semi-metal brake blocks, less-metal brake blocks, NAO formula brake blocks, ceramic brake blocks and NAO ceramic brake blocks.

The production process of the automobile brake pad comprises the steps of mixing materials, carrying out cold pressing, hot pressing or direct hot pressing, carrying out heat treatment and machining to form a finished product, wherein the purpose of hot pressing is to solidify resin to form a product with a certain shape and density, and chemical reaction of organic matters in the raw materials can be completed in a heat treatment box. The traditional hot pressing process in China is completed by using a die, the original cylindrical die transfers heat from the periphery to the middle, the heat conduction path is long, and the product is heated unevenly, so that the process requirement can be met only by using longer curing time, the energy consumption is high, and the cost is increased. Later study western adopts row's mould or plate mould, follows upper and lower two sides heat conduction, and the route is short, is heated more evenly than originally, but production efficiency is not high to there is dust pollution in the operation process. The process of the roller press is a hot extrusion process, heat and force are directly applied to the friction material, the heating time is short, the processed product is in a belt shape, continuous production can be realized, and the energy consumption is reduced. Meanwhile, the production efficiency is improved, and compared with the traditional process, the method has the characteristics of low pollution and environmental protection.
However, the existing processing production line mainly has the following defects: the tabletting device mainly has the defects of complex structure, and the deviation of the tabletting position easily caused by the incapability of realizing good clamping and adjustment of the female die of the tabletting machine. The polishing device mainly has the defects that the polishing position is easy to deviate and the like due to the fact that the structure is complex, the manufacturing cost is high, and the brake pad clamp cannot be well adjusted. The drying device mainly has the defects of uneven product quality caused by uneven drying and the like, and the main reason is that the brake pad can not conduct heat uniformly. Meanwhile, the degree of automation is not high, and unmanned production cannot be realized.

The connecting holes of the scraping and stirring arms and the blades are long open holes, and the gap between the blades and the tank body can be conveniently adjusted in the blade abrasion direction after the blades are abraded. The design selects the arrangement angle of the adjacent stirring arms on the stirring shaft to be 60 degrees. The blade mount angle is the angle between the blade and the shaft. The mounting angle is less than 90 deg. How the mixture moves, where the mixture moves, the speed of the mixture moving and the like in the main machine tank body are all related to the installation angle of the blades.
