Description

Technical Field

[0001] The utility model relates to the technical field of rubber reprocessing, in particular to a waste rubber softening device for rubber production. Background Art

[0002] Rubber is an elastic polymer material with the property of reversible deformation. It is involved in all aspects of daily life and is a high-demand material. The recycling of waste rubber not only saves resources, but also avoids environmental pollution. The basic process of recycling waste rubber includes a series of processes such as plasticizing, mixing, calendering or extrusion, molding and vulcanization. Traditional rubber softening machines directly put the waste rubber into a heating barrel for softening after it is roughly crushed by a crushing roller.

In this process, since the crushing rollers break the rubber, the nozzle water pipes clean the rubber more cleanly, so as to achieve the purpose of cleaning the dirt attached to the rubber;

[0004] However, in the above scheme, after the rubber blocks are crushed by the crushing roller, the crushed rubber blocks fall directly on the conveyor belt, which easily causes the crushed rubber blocks to pile up. When the accumulated rubber blocks are washed and dried by the nozzle water pipe and the electric heating pipe, the washing effect is poor, and the accumulated rubber blocks affect the drying effect. Therefore, the utility model designs a waste rubber softening device for rubber production to solve the problems existing in the prior art. Utility Model Content

[0028] Working principle: Turn on the power supply. When softening large pieces of waste rubber blocks, pour the waste rubber blocks from the top of the crushing box 2, start the first servo motor 5, and the output end of the first servo motor 5 drives the rotating shaft 6 to rotate, so that the second bevel gear 601 at the upper end of the rotating shaft 6 is meshed with the first bevel gear 302 at one end of the corresponding crushing roller 3, so that the crushing roller 3 rotates, and the crushing roller 3 is meshed with the gear 301 at one end of the other crushing roller 3 through the gear 301 at one end. At this time, the two crushing rollers 3 bite each other to crush the rubber blocks, and the crushed rubber blocks fall onto the surface of the water filter plate 7 after passing through the discharge port. In the process of the output end of the first servo motor 5 driving the rotating shaft 6 to rotate, the cam 602 on the surface of the rotating shaft 6 intermittently squeezes the surface of one end of the water filter plate 7 through rotation, and when the cam 602 is not pressed against one end of the water filter plate 7, the return spring 803 is elastically reset after being stressed to push the water filter plate 7 to move in the direction of the cam 602, so that the crushed rubber blocks on the surface of the water filter plate 7 enter The rubber blocks on the surface of the water filter plate 7 are shaken to make the accumulated rubber blocks flattened quickly, and the crushed rubber blocks are prevented from accumulating and affecting the subsequent cleaning and drying. The rubber blocks on the surface of the water filter plate 7 are shaken and rolled to the other end of the drying box 1. At the same time, the rubber blocks are rinsed by the nozzle water pipe 11. After rinsing, the rubber blocks are dried by the heater 12. While the rubber blocks are crushed, strong suction is generated through the air inlet end of the exhaust fan 1005. At this time, the crushed dust enters the dust box 1001 through the dust hood 1002, and is filtered twice by the first filter plate 1003 and the second filter plate 1004. The gas is discharged from the air outlet hood 1006 into the drying box 1. While the heater 12 dries the rinsed rubber blocks, the gas blown out of the air outlet hood 1006 accelerates the drying speed of the rubber block surface, and finally falls into the heating and softening box 1301, and then the stirring blade 1304 on the surface of the rotating shaft 1303 is driven to rotate by the output end of the second servo motor 1305 to soften and stir the heated rubber blocks.
