Description

Technical Field

[0001] This utility model relates to the field of waste rubber recycling, and in particular to a rubber breaking mechanism for rubber refining. Background Technology

[0002] With the improvement of people's living standards, cars have entered thousands of households, bringing with them the problem of disposing of a large number of waste tires. Given the increasing scarcity of rubber resources, the recycling of waste tires has significant social and economic importance. The general recycling process for rubber tires involves: crushing, screening for metals and glass fibers, secondary crushing, and secondary production. Rubber breaker is primarily used for crushing waste rubber and reclaimed rubber; therefore, it plays a crucial role in the field of waste rubber recycling.

[0003] A search of Chinese Patent Publication No. CN216658572U reveals a rubber breaking mechanism for rubber mixing, comprising a breaking box, breaking rollers, slide rails, sliders, cleaning brushes, springs, a screening device, a return conveyor device, a receiving box, and a motor. The inner cavity of the breaking box is rotatably connected to a pair of breaking rollers via bearing seats. A pair of motors are fixedly installed on the outer side of the breaking box, and the output end of the motors is fixedly connected to the breaking rollers. Slide rails are fixedly installed on both the left and right sides of the top plate of the inner cavity of the breaking box, and the slide rails are slidably connected to the sliders. A cleaning brush is fixedly installed on the slider, and the outer side of the cleaning brush is connected to the breaking box via springs. A screening device is installed below the breaking rollers. The left side of the breaking box is fixedly connected to the return conveyor device, and the right side of the breaking box is fixedly installed with a receiving box.

[0004] Because the rubber breaker gradually heats up during operation, the rubber becomes more viscous after heating, making it difficult to clean directly with a brush. In fact, the rubber may stick to the brush and affect its subsequent use. Utility Model Content

[0005] The purpose of this invention is to provide a rubber breaking mechanism for rubber refining in order to solve the above-mentioned problems.

[0006] This utility model achieves the above objectives through the following technical solutions:

[0026] The present invention will be further described below with reference to the accompanying drawings:

[0027] like Figures 1-6 As shown, a rubber breaking mechanism for rubber refining includes a box body 1. Support legs 101 are fixedly connected to the four corners of the bottom of the box body 1, and a protective cover 102 is fixedly connected to the top of the box body 1. The protective cover 102 is a funnel shape with the small opening facing downwards.

[0028] The bottom of the box 1 is provided with a feeding assembly, which includes a guide plate 103 fixedly connected to the bottom of the box 1. The guide plate 103 is inclined and the inner bottom wall of the box 1 has a feeding port. The guide plate 103 is located below the feeding port.

[0029] The housing 1 is equipped with a rubber breaking assembly, which includes two rubber breaking rollers 201 rotatably connected between the inner walls of the housing 1. The two rubber breaking rollers 201 rotate in opposite directions. A housing 202 is bolted to the side of the housing 1 away from the air supply assembly. A rotary motor for driving the two rubber breaking rollers 201 is installed inside the housing 202. The top of the housing 202 is provided with heat dissipation holes. The outer wall of the rubber breaking rollers 201 is provided with several textures. The textures are inclined relative to the axis of the rubber breaking rollers 201, so that the two rubber breaking rollers 201 can provide shear force to the rubber when they rotate, thereby improving the rubber breaking effect.

[0030] The housing 1 is equipped with a cleaning assembly. Two sets of cleaning assemblies are symmetrically arranged about the rubber breaking assembly. The cleaning assembly includes a cleaning roller 301 rotatably connected between the inner walls of the housing 1 and a belt 302. One end of both the cleaning roller 301 and the rubber breaking roller 201 extends out of the housing 1. The cleaning roller 301 abuts against the rubber breaking roller 201. The belt 302 is connected between the cleaning roller 301 and the rubber breaking roller 201 through a pulley. The belt 302 is located outside the housing 1. The transmission between the cleaning roller 301 and the rubber breaking roller 201 is realized through the pulley and the belt 302.

[0031] The cleaning roller 301 has a ventilation cavity inside, and a number of air blowing holes 401 are opened on the outer wall of the cleaning roller 301. The air blowing holes 401 are inclined so that the air blown out of the air blowing holes 401 blows along the texture of the surface of the rubber breaking roller 201. The number of air blowing holes 401 are inclined relative to the axis of the rubber breaking roller 201. An air supply assembly is provided on the side wall of the housing 1. The air supply assembly is used to supply air to the ventilation cavity opened inside the cleaning roller 301. The air supply assembly includes a fan 402 bolted to one side of the housing 1. An air supply pipe 403 is fixedly connected to the air outlet of the fan 402. The ports of the air supply pipe 403 extend into the two cleaning rollers 301 respectively. The air supply pipe 403 is rotatably connected to the cleaning roller 301.

[0032] Working principle: During use, the rotary motor inside the housing 202 drives the rubber-breaking roller 201 to rotate. Waste rubber parts are placed between the two rubber-breaking rollers 201, and the rubber parts are broken by the rubber-breaking rollers 201. At the same time as the rubber-breaking rollers 201 rotate, the cleaning roller 301 is driven to rotate by the transmission between the pulley and the belt 302. The cleaning roller 301 cleans the rubber fragments stuck in the grooves of the rubber-breaking rollers 201. At the same time as breaking the rubber, the blower 402 is started, and air is supplied to the inside of the cleaning roller 301 through the air supply pipe 403. As the cleaning roller 301 rotates, the air blows in the direction of the grooves of the rubber-breaking rollers 201. On the one hand, it is convenient to cool the softened rubber and make it solidify so that it is easier to clean. On the other hand, the air blows loosen the rubber stuck in the rubber-breaking rollers 201, improving the cleaning efficiency. The broken rubber fragments are discharged from the housing 1 under the guidance of the guide plate 103.

[0033] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
