Description

Technical Field

[0001] The utility model relates to the technical field of recycled rubber production, in particular to a high-efficiency mixing machine used for recycled rubber production. Background Art

[0002] The recycling of waste rubber refers to the use of physical or chemical methods to restore the cross-linked network structure of the rubber to a linear state, that is, the sulfur-sulfur (S-S) bonds are reopened while the carbon-carbon (C-C) bonds are minimized, making the rubber reprocessable and maintaining or restoring the original physical properties of the rubber. In the process of recycled rubber production, a mixer is required to mix the rubber and compounding agents.

[0003] A rubber production mixing machine with publication number CN 219311708 U comprises a main barrel, the outer surface of which is provided with a transverse spiral pipe, a rotating rod is placed inside the main barrel, the rotating rod is rotatably connected to the left and right inner walls of the main barrel, the right end of the rotating rod passes through the main barrel, an auger is fixedly connected to the outer surface of the rotating rod, a feeding funnel is fixedly connected to the outer surface of the main barrel, the upper end of the feeding funnel is fixedly connected to the feeding barrel, and a vertical spiral pipe is installed on the outer surface of the feeding barrel. The rubber production mixing machine, by providing a transverse spiral pipe and a vertical spiral pipe, can preheat the raw materials in the feeding barrel while hot steam heats the main barrel, thereby reducing the time required for heating, and solving the problem that the common rubber production mixing machine uses a heating device to directly heat the working barrel to work, resulting in a long length of the working barrel to meet production requirements, resulting in a long working time required for processing.

[0004] Although this device reduces the time required for heating, it heats the outer wall of the main barrel to increase the temperature of the inner wall of the main barrel during the production process, thereby transferring heat to the rubber in the main barrel, causing the temperature of the rubber near the inside to rise more slowly, resulting in uneven temperature of the rubber in the main barrel, and the device cannot scrape off the rubber adhering to the inner wall of the main barrel, resulting in waste of raw materials when discharging. In view of this, we propose an efficient mixer for the production of recycled rubber. Utility Model Content

[0032] Specifically, a top cover 18 is provided on the top of the feed hopper 16, and a sealing plug 181 is fixed to the bottom of the top cover 18 by glue to play a sealing role.

A handle 182 is fixed to the top of the top cover 18 by bolts to facilitate the user to move the top cover 18.

[0033] Furthermore, a driving mechanism 2 is provided on the right side surface of the main cylinder 11, and the driving mechanism 2 includes a driving motor 21. The driving motor 21 is fixedly connected to the right side surface of the main cylinder 11 by bolts, and the output shaft of the driving motor 21 is coaxially connected to a limiting seat 22 for limiting the position of the moving frame 25.
