[0002] With the rapid development of the rubber industry, the recycling and reuse of waste rubber has become increasingly prominent. The recycling of waste rubber can not only reduce environmental pollution, but also save resources and achieve sustainable development. In the recycling process of waste rubber, desulfurization is an important step. Through desulfurization, the elasticity of waste rubber can be restored and its reuse value can be improved. However, the waste rubber after desulfurization needs to be sheared in the subsequent production process to adapt to different production needs.

[0003] The Chinese utility model patent currently announced as: CN216992677U discloses a shearing device for recycled rubber production, which is provided with a shell, one end of the shell is provided with a feed port, and the other end is provided with a discharge port; a rotating shaft is provided inside the shell, and one end of the rotating shaft is connected to a drive motor; a three-section shearing mechanism is provided in the shell from the feed end to the discharge end, and each section of the shearing mechanism includes a spiral blade fixed on the rotating shaft and a plurality of groups of moving knives, and a plurality of groups of fixed knives fixed on the inner wall of the shell; the spiral blade is close to the feed end, and each group of moving knives is provided with three moving blades distributed at equal intervals around the circumference, and each group of fixed knives includes three fixed blades distributed at equal intervals around the circumference; the moving knives and the fixed knives are alternately arranged along the axial direction of the rotating shaft, and the raw material is sheared three times by the cooperation of the segmented spiral feeding piece and the shearing zone, so that the shearing is more thorough, the shearing efficiency is higher, and a lot of time is saved.

[0004] Although this patent can shear the raw materials three times through segmented spiral feeding, there is still a situation where the waste rubber is not sheared properly three times, and the size of the rubber particles after shearing cannot be guaranteed to be uniform, which is likely to affect the quality of subsequent processing. Utility Model Content

[0005] The utility model aims to provide a shearing device for waste rubber after desulfurization production, which solves the problem that the existing waste rubber shearing device has the problem that the waste rubber cannot be sheared in place three times, the size of the rubber particles after shearing cannot be guaranteed to be uniform, and the quality of subsequent processing is easily affected.

[0006] The above technical purpose of the utility model is achieved through the following technical scheme: a shearing device for waste rubber desulfurization production, comprising a shell, a feed inlet is provided on the shell, and a circulation mechanism and a shearing mechanism are provided inside the shell;

[0007] The circulation mechanism includes a circulation drum, a spiral plate, a connecting rod and a first motor. The circulation drum is arranged on a shell, the spiral plate is arranged inside the circulation drum, the connecting rod is arranged inside the circulation drum and the spiral plate is arranged on the outer wall of the connecting rod, the other end of the connecting rod extends to the outside of the circulation drum, and the first motor is arranged on the connecting rod.

[0008] The above technical scheme is adopted, by setting a shell, a feed port, a circulation mechanism and a shearing mechanism. When in use, the waste rubber can first be transported into the interior of the shell through the feed port, and then sheared by the shearing mechanism. At this time, the waste rubber that is not sheared in place is lifted upward by the circulation mechanism, so that the waste rubber that is not sheared in place is sheared again by the shearing mechanism until all the waste rubber is sheared in place, thereby ensuring the uniformity of the rubber particles after shearing and avoiding affecting the subsequent processing quality. The circulation mechanism includes a circulation cylinder, a spiral plate, a connecting rod and a first motor. When in use, the circulation cylinder is set on the cylinder body, and the rubber that is not sheared in place will slide to the inside of the circulation cylinder, and then the first motor is turned on, so that the first motor drives the connecting rod to rotate, and then the spiral plate is rotated, so that the spiral plate drives the rubber that is not sheared in place to be lifted upward. When the rubber is lifted upward to the highest point, it can re-enter the shell and be repeatedly sheared.

[0009] Further: the shearing mechanism includes a second motor, a rotating shaft and a shearing blade, the second motor is arranged on the shell, the rotating shaft is arranged on the output shaft of the second motor, the rotating shaft extends to the interior of the shell, the shearing blade is arranged on the rotating shaft, and the shearing blades are several in number and arranged crosswise.

[0010] By adopting the above technical solution, a second motor, a rotating shaft and a shearing blade are set. When in use, the second motor is first turned on so that the output shaft of the second motor drives the rotating shaft to rotate, and then the rotating shaft drives the shearing blade to rotate, so as to shear the waste rubber entering the shell. Then, the number of shearing blades is several and they are cross-arranged, which can improve the efficiency of rubber shearing.

[0011] Furthermore: a tilting block is arranged at the bottom of the shell, the tilting block is tilted toward one side of the circulation drum, a through hole is arranged on the tilting block, and the through hole passes through the tilting block and the bottom of the shell.

[0012] By adopting the above technical solution, by setting the inclined block and the through hole, when the waste rubber is sheared by the shear blade, it enters the inclined block, the rubber particles that meet the requirements are discharged through the through hole, and the rubber that does not meet the requirements slides on the inclined block into the circulation drum due to its own gravity.

[0013] Further: a flow guide cover is arranged inside the shell, the cross section of the flow guide cover is trapezoidal, and the flow guide cover is arranged between the feed inlet and the shearing blade.

[0014] By adopting the above technical solution, a flow guide cover is set. When in use, the flow guide cover can not only guide the waste rubber entering the shell through the feed port, but also guide the rubber discharged into the shell after being lifted by the spiral plate, so that the waste rubber can fully contact the shear blade and can be better sheared, thereby improving the shearing efficiency.

[0015] Furthermore: a collecting cover is arranged at the bottom of the shell, a sealing door is hingedly arranged on the collecting cover, and a handle is arranged on the sealing door.

[0016] By adopting the above technical solution, a collecting hood, a sealing door and a handle are provided. When the sheared rubber particles pass through the through hole, they can enter the collecting hood. When all the waste rubber is sheared, the sealing door can be opened through the handle to uniformly collect and process the rubber particles inside the collecting hood.

[0017] Further: an air guide duct is arranged on the collecting hood.

[0018] By adopting the above technical solution and setting up an air duct, a large amount of dust can be generated during the shearing process of the waste rubber, and then the dust can enter the collecting hood through the through hole. At this time, the air duct is connected to the external dust removal device to remove the dust inside the collecting hood.

[0019] Further: support columns are arranged at the bottom of the collecting cover, and the number of the support columns is four and they are arranged in a circle.

[0020] By adopting the above technical solution, by setting a support column, when in use, the support column collects the hood and the shell for support and fixation, thereby improving the stability of the collection hood and the shell.

[0021] Further: reinforcing ribs are arranged on the four support columns.

[0022] By adopting the above technical solution and arranging reinforcing ribs, the reinforcing ribs can improve the strength of the support column during use, thereby improving the stability of the shell.

[0023] In summary, the utility model has the following beneficial effects:

[0024] By setting a circulation cylinder, a spiral plate, a connecting rod and a first motor, when in use, the circulation cylinder is set on the cylinder body, and the rubber that is not sheared in place will slide to the inside of the circulation cylinder, and then the first motor is turned on to make the first motor drive the connecting rod to rotate, and then the spiral plate is rotated, so that the spiral plate drives the rubber that is not sheared in place to be lifted upward, and when the rubber is lifted upward to the highest point, it can re-enter the shell and be repeatedly sheared.

[0025] By setting a second motor, a rotating shaft and a shearing blade, when in use, first turn on the second motor so that the output shaft of the second motor drives the rotating shaft to rotate, and then the rotating shaft drives the shearing blade to rotate, so as to shear the waste rubber entering the shell, and then the number of shearing blades is several and they are cross-arranged, which can improve the efficiency of rubber shearing.

[0026] Based on the above-mentioned improvements, the overall technical effect achieved by the device is that the waste rubber that is not sheared in place can be lifted upward through the circulation mechanism, so that the waste rubber that is not sheared in place can be sheared again by the shearing mechanism until all the waste rubber is sheared in place, thereby ensuring the uniformity of the rubber particles after shearing and avoiding affecting the subsequent processing quality.
