Description

Technical Field

[0001] The utility model relates to the technical field of rubber mixing machines, in particular to a discharging device of a rubber mixing machine. Background Art

[0002] Rubber mixing machines are divided into two categories: open type and closed type. Open type machines are mainly used for hot mixing, sheeting, rubber breaking, plasticizing and mixing of rubber. The rubber mixing process refers to the process of chemical reaction and physical treatment of rubber raw materials to make them into rubber materials that can be used to manufacture various rubber products. Open type rubber mixing machines are a more commonly used type of rubber mixing equipment. When processing rubber (silicone rubber, silica gel, etc.) products, the staff will put the rubber that has been squeezed once back between two mixing rollers for mixing again. Due to the large volume of rubber, the staff needs to pick up the rubber pressed into sheets by hand for winding when turning it. The operation is not only difficult but also greatly increases the workload. Secondly, when picking up and turning the rubber, a pair of mixing rollers are always in a rotating state. , which brings safety hazards to the staff. In order to improve the above-mentioned disadvantages, the patent with application number 202321318474.1 in the public technology has been applied, including a base, a support box, a rubber mixing roller and a scraper guide assembly. The scraper guide assembly includes a connecting rod arranged between a pair of the support boxes. Although the hanging shovel can scrape the bottom of the outer wall of the rubber mixing roller to prevent the rubber from sticking to the outer wall of the rubber mixing roller, it can also realize the folding and stacking of the rubber, which is conducive to the folded rubber being put into the rubber mixing roller again, but the scraper device in its discharging mechanism does not have the function of assisting the rubber to detach, and the probability of adhesion between the scraper surface that scrapes the rubber mixing roller and the rubber moving downward is high, which is not conducive to the smooth discharging of the rubber mixer.

The following mainly introduces the working principles and processes, and no detailed description of the electrical control is given.

[0022] The scraper device in its discharging mechanism does not have the function of assisting the rubber to separate. The probability of adhesion between the scraper surface that scrapes the rubber mixing roller and the rubber moving downward is high, which is not conducive to the smooth discharging of the rubber mixing machine.

[0023] In view of this, the utility model discloses a discharging device of a rubber mixing machine. Through the cooperation among a support plate, a rotating rod, a conical cylinder, an air outlet, a sealing plate, a bolt, a motor and an auxiliary unit, the conical part of the top end of the conical cylinder is fitted with the inner side below the outer wall of the rubber mixing roller. In this process, the surface of the conical cylinder with the blowing hole needs to be oriented toward the path direction after the rubber is squeezed. During the period when the rubber mixing roller squeezes and mixes the rubber, the conical part of the top end of the conical cylinder will scratch the outer wall of the rubber mixing roller, which can effectively prevent the rubber from sticking to the rubber mixing roller. During this period, the staff connects the hose to the external air supply device to start it, and injects air into the interior of the conical cylinder through the hose and the air injection pipe. The injected air can be blown out through the air outlet. The force of the blown air will act on the rubber on the outside of the conical cylinder, which can provide an auxiliary function for the rubber to detach from the surface of the conical cylinder that has a scratching effect, which can greatly reduce the probability of sticking between the rubber and the conical cylinder, and facilitate the smooth discharging of the rubber mixing machine.
