Description

Technical Field

[0001] The utility model relates to the field of automobiles, in particular to a coating device for processing isolation raw materials for automobile hot-melt damping plates. Background Art

[0002] With the rapid development of the automobile industry and consumers' increasing requirements for driving experience, in-vehicle noise control and ride comfort have become important factors that cannot be ignored in the process of automobile design and manufacturing. Among the various methods to solve the problem of automobile noise, the application of damping materials has been proven to be an effective means. Through its excellent viscoelastic properties, damping materials can gradually attenuate or reduce vibrations caused by external or inherent reasons of the system itself, thereby reducing in-vehicle noise.

[0003] In the production and processing of automotive damping materials, hot-melt damping plates have been widely used due to their unique molding process and excellent damping performance. However, in the processing of hot-melt damping plates, due to the high viscosity of raw materials such as asphalt, the damping plates are prone to adhesion during stacking, storage, transportation and use. This not only affects the use effect of the damping plates, but also reduces work efficiency and may even lead to the scrapping of the damping plates. To solve this problem, an isolation agent can be coated on the surface of the damping plates. The isolation agent can effectively reduce the viscosity of the damping plate surface and prevent it from sticking during stacking, storage, transportation and use.

[0004] After searching, Chinese Patent Announcement No.: CN221016751U discloses a coating device for insulating raw materials for processing hot-melt damping plates in automobiles, including a working cabin, the lower end outer surface of the working cabin is fixedly connected to a base, and the inner surface of one side of the working cabin is provided with a double-sided adjustable automatic coating device for improving the coating efficiency of the insulating raw materials of the damping plates, and the double-sided adjustable automatic coating device includes a mounting seat and a cylinder, and the upper end outer surface of the mounting seat is provided with a storage tank, and one side of the storage tank is provided with a pump body.

[0037] Working principle: When in use, after placing the damping plate between the two groups of positioning blocks 42, start the electric telescopic rod 52 to push the connecting block 53 to move and pull the two groups of moving blocks 51, and pull the two groups of positioning frames 54 toward the middle through the two groups of moving blocks 51, so that the damping plate can be pushed to the middle position, and the damping plate can be clamped and positioned in the middle position through the cooperation of multiple groups of positioning frames 54 to prevent displacement during fixation, so that multiple groups of rubber pads increase the stability of clamping, making operation more convenient.
