Description

Technical Field

[0001] The utility model relates to the technical field of waste rubber processing, in particular to a waste rubber melting device. Background Art

[0002] Rubber refers to a highly elastic polymer material with reversible deformation. It is elastic and can produce large deformation under very small external force. It can return to its original shape after the external force is removed. Rubber is a completely amorphous polymer with a low glass transition temperature and a large molecular weight. Rubber is divided into two types: natural rubber and synthetic rubber. Natural rubber is made by extracting gum from plants such as rubber trees and rubber grass, while synthetic rubber is obtained by polymerization of various monomers. Rubber products are widely used in industry and all aspects of life.

[0003] Waste rubber is usually recycled and reused. When processing waste rubber, it is first necessary to melt the rubber for subsequent processing.

However, there is a problem with this method, that is, the size of the crushed rubber particles is not uniform. Therefore, during the melting process, large rubber particles take longer to melt completely, while the melted small rubber particles continue to be heated, resulting in overheating, which in turn affects the quality of its subsequent processing.

[0029] The waste rubber melting device according to the embodiment of the present utility model will be described below in conjunction with the accompanying drawings.

[0046] Specifically, the operation of the second motor 33 synchronously drives the transmission gear 31 to rotate, and the rotation of the transmission gear 31 synchronously drives the crushing roller 12 to rotate to crush the material. At the same time, the rotation of the transmission gear 31 cooperates with the upper transmission gear 34 and the first synchronous toothed belt 35 to synchronously drive the scraper mechanism 2 to operate.

The rotation of the lower transmission gear 38 synchronously drives the drive sprocket 36 corresponding to its position to rotate. The rotation of this group of drive sprockets 36 synchronously drives other groups of drive sprockets 36 to rotate through the synchronous chain belt 37.

[0049] It should be noted that the material guiding frame 43 described in this embodiment is located at one end of the interior of the machine body 1 corresponding to the position of the screen frame 13 , and the material guiding frame 43 is used to receive the material pushed down from the screen frame 13 .

[0050] Specifically, the rotation of the first bevel gear 311 synchronously drives the second bevel gear 44 to rotate, and the rotation of the second bevel gear 44 synchronously drives the second spiral conveying auger 42 to rotate.
