Description

Technical Field

[0001] The utility model relates to the technical field of rubber processing, and more specifically, to a rubber grinding machine. Background Art

[0002] The rubber industry occupies a very important position in the national economy, but its waste is one of the sources of environmental pollution. Recycling and processing waste rubber products such as automobile tires and shoe soles requires the rubber products to be repeatedly crushed into rubber particles about 5 mm in size.

[0003] Chinese Patent with application number CN202021038407.0 discloses a rubber particle grinding machine that is not prone to blockage, including a grinding box. A feed inlet is provided at the middle position of the upper surface of the grinding box. Two limiting plates are symmetrically arranged on one side below the grinding box. A first gear and a second gear are respectively rotatably installed by embedding on the front surface of one of the limiting plates. A rotating motor is fixedly arranged on the front surface of the second gear. One end of the first gear is horizontally connected to a rotating shaft.

[0004] Although this grinding machine can grind rubber particles, during the grinding process, the rubber particles will generate heat due to friction. The increase in temperature will cause the rubber particles to soften and adhere to the grinding components, further affecting the grinding effect.

[0005] Therefore, a rubber grinding machine is proposed. Summary of the Utility Model

[0006] The purpose of the utility model is to overcome the deficiencies of the prior art and provide a rubber grinding machine.

[0007] The purpose of the utility model is achieved by the following technical solutions:

[0008] A rubber grinding machine includes a support assembly and a grinding assembly. The support assembly includes a bottom plate and a top plate arranged in parallel at intervals, and the top plate and the bottom plate are connected by at least one support column. The grinding assembly includes a ring connected to the top plate, an upper grinding plate rotatably connected to the inner ring of the ring, a driving mechanism arranged on the ring, and a lower grinding plate arranged on the top surface of the bottom plate. During grinding, the driving mechanism drives the upper grinding plate to rotate to grind the rubber located between the upper grinding plate and the lower grinding plate. A cooling mechanism is arranged on the upper grinding plate.

[0009] Further, in the present utility model, the cooling mechanism includes a cooling pipe embedded in the upper grinding disc and two concentric annular liquid supply channels arranged on the top surface of the upper grinding disc. The two ends of the cooling pipe and the two annular liquid supply channels are respectively communicated in one-to-one correspondence through two pipes; the upper part of any of the annular liquid supply channels is open, and a sealing ring is slidably and sealingly connected to the opening; a liquid inlet pipe is penetrated through one of the sealing rings, and a liquid outlet pipe is penetrated through the other sealing ring.

[0010] Further, in the present utility model, the driving mechanism is a motor, the driving end of the motor is drivingly connected with a gear, and a gear ring meshing with the gear is arranged on the outer edge of the upper grinding disc.

[0011] Further, in the present utility model, a feeding mechanism is further included. The feeding mechanism includes a feeding disc connected to the ring and a feeding hopper arranged on the feeding disc. The bottom surface of the feeding disc is attached to the top surface of the upper grinding disc. A feeding port is penetrated through the upper grinding disc, a blanking port adapted to the feeding port is opened on the feeding disc, and the blanking port is communicated with the feeding hopper.

[0012] Further, in the present utility model, the ring and the top plate are connected through a plurality of telescopic rods.

[0013] The beneficial effects of the present utility model are as follows:

[0014] The present utility model provides a rubber grinding machine. When the upper grinding disc needs to be cooled during the grinding process, the supporting liquid supply mechanism injects the coolant into the annular liquid supply channel through the liquid inlet pipe. Due to the existence of the sealing ring, the coolant cannot flow out from the upper opening of the annular liquid supply channel. The coolant entering the annular liquid supply channel flows into the cooling pipe through the pipe, and then flows into another annular liquid supply channel through the other end of the cooling pipe. The supporting liquid supply mechanism extracts the coolant in the current annular liquid supply channel through the liquid outlet pipe. In this way, the coolant can circulate in the annular liquid supply channel and the cooling pipe, thereby improving the cooling effect. When the upper grinding disc rotates self during grinding, the rotation of the upper grinding disc drives the two annular liquid supply channels to rotate. However, since the sealing ring is slidably and sealingly connected to the annular liquid supply channel, the rotation of the two annular liquid supply channels does not drive the two sealing rings to rotate. Therefore, the presence of the liquid inlet pipe and the liquid outlet pipe does not interfere with the rotation of the annular liquid supply channel. Description of the Drawings

Detailed implementation manners

[0019] Next, the technical solutions of the present utility model will be clearly and completely described in conjunction with the embodiments. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative efforts belong to the scope of protection of the present utility model.

[0020] Please refer to Figures 1-3 , the present utility model provides a technical solution:

[0021] A rubber grinding machine includes a support assembly and a grinding assembly. The support assembly includes a bottom plate 101 and a top plate 102 that are arranged in parallel at intervals, and the top plate 102 and the bottom plate 101 are connected by at least one support column 103; the grinding assembly includes a ring 201 connected to the top plate 102, an upper grinding disc 202 rotatably connected to the inner circle of the ring 201, a driving mechanism 203 arranged on the ring 201, and a lower grinding disc 204 arranged on the top surface of the bottom plate 101; during grinding, the driving mechanism 203 drives the upper grinding disc 202 to rotate to grind the rubber located between the upper grinding disc 202 and the lower grinding disc 204; a cooling mechanism is arranged on the upper grinding disc 202, and it can cool the upper grinding disc 202 during grinding, thereby reducing the probability of softening of rubber particles and sticking to the grinding components due to the rise in temperature, and further improving the grinding effect.

[0022] In some implementation manners of this embodiment, the cooling mechanism includes a cooling pipe 301 embedded in the upper grinding disc 202 and two concentric annular liquid supply flow channels 302 arranged on the top surface of the upper grinding disc 202. The two ends of the cooling pipe 301 and the two annular liquid supply flow channels 302 are respectively connected in one-to-one correspondence through two pipes; the upper part of any annular liquid supply flow channel 302 is open, and a sealing ring 303 is slidably and sealingly connected at the opening; a liquid inlet pipe 304 penetrates through one sealing ring 303, and a liquid outlet pipe 305 penetrates through the other sealing ring 303. The liquid inlet pipe 304 and the liquid outlet pipe 305 are connected to a supporting liquid supply mechanism for use.

[0023] When the upper grinding disc 202 needs to be cooled during the grinding process, the supporting liquid supply mechanism injects the coolant into the annular liquid supply channel 302 through the liquid inlet pipe 304. Due to the presence of the sealing ring 303, the coolant cannot flow out from the upper opening of the annular liquid supply channel 302. The coolant entering the annular liquid supply channel 302 flows into the cooling pipe 301 through the pipeline, and then flows into another annular liquid supply channel 302 through the other end of the cooling pipe 301. The supporting liquid supply mechanism draws away the coolant in the current annular liquid supply channel 302 through the liquid outlet pipe 305, so that the coolant can circulate in the annular liquid supply channel 302 and the cooling pipe 301, thereby improving the cooling effect. When grinding, the upper grinding disc 202 rotates, and the rotation of the upper grinding disc 202 drives the two annular liquid supply channels 302 to rotate. However, since the sealing ring 303 and the annular liquid supply channels 302 are connected by sliding sealing, the rotation of the two annular liquid supply channels 302 will not drive the two sealing rings 303 to rotate, so that the existence of the liquid inlet pipe 304 and the liquid outlet pipe 305 will not interfere with the rotation of the annular liquid supply channels 302. In addition, the sliding sealing method of the sealing ring 303 and the annular liquid supply channels 302 is a prior art, which will not be described in detail here.

[0024] In other implementations of this embodiment, a cooling structure may also be designed in the lower grinding disc 204 to facilitate cooling of the lower grinding disc 204 .

[0025] In order to facilitate the upper grinding disc 202 to rotate and cooperate with the lower grinding disc 204 to perform grinding work, the driving mechanism 203 adopts a motor, the driving end of the motor is connected to the gear 401, and the outer edge of the upper grinding disc 202 is provided with a gear ring 402 meshing with the gear 401.

[0026] In order to facilitate the delivery of the rubber block to be ground between the upper grinding disc 202 and the lower grinding disc 204, a feeding mechanism is installed above the upper grinding disc 202. The feeding mechanism includes a feeding disc 501 connected to the ring 201 and a feeding hopper 502 arranged on the feeding disc 501. The bottom surface of the feeding disc 501 is in contact with the top surface of the upper grinding disc 202. A feeding port 503 is opened through the upper grinding disc 202. A drop port (not shown in the figure) adapted to the feeding port 503 is opened on the feeding disc 501, and the drop port is connected to the feeding hopper 502. During grinding, the upper grinding disc 202 rotates under the control of the driving mechanism 203 and the gear 401 ring gear 402 mechanism. During the rotation of the upper grinding disc 202, the feed port 503 of the upper grinding disc 202 will be connected with the feed port. After the connection, the rubber block in the feed hopper 502 can fall into the space between the upper grinding disc 202 and the lower grinding disc 204 through the feed port and the feed port 503 in sequence for grinding. The design of the bottom surface of the feed disc 501 fitting with the top surface of the upper grinding disc 202 can prevent the rubber block from entering between the feed disc 501 and the upper grinding disc 202, thereby affecting the rotation of the upper grinding disc 202.

[0027] In order to facilitate the adjustment of the distance between the upper grinding plate 202 and the lower grinding plate 204 to control the size of the grinding particles, the special ring 201 and the top plate 102 are connected by a number of telescopic rods 601. The telescopic rod 601 can use the telescopic structure in the prior art, and its telescopic action can be driven by a servo motor or the like. In addition, the telescopic rod 601 can also use a linear motion mechanism such as a hydraulic cylinder to achieve the telescopic action, so as to achieve the purpose of controlling the distance between the upper grinding plate 202 and the lower grinding plate 204.

[0028] Working principle:

[0029] Before grinding, first control the telescopic length of the telescopic rod 601 according to the grinding requirements to adjust the distance between the upper grinding plate 202 and the lower grinding plate 204. After this distance is adjusted, the grinding work can be started.

[0030] During the grinding process, when it is necessary to cool the upper grinding plate 202, the supporting liquid supply mechanism injects the coolant into the annular liquid supply channel 302 through the liquid inlet pipe 304. Due to the presence of the sealing ring 303, the coolant cannot flow out from the upper opening of the annular liquid supply channel 302. The coolant entering the annular liquid supply channel 302 flows into the cooling pipe 301 through the pipe, and then flows into another annular liquid supply channel 302 through the other end of the cooling pipe 301. The supporting liquid supply mechanism pumps away the coolant in the current annular liquid supply channel 302 through the liquid outlet pipe 305. In this way, the coolant can circulate in the annular liquid supply channel 302 and the cooling pipe 301, thereby improving the cooling effect.

[0031] The above is only the preferred embodiment of the present invention. It should be understood that the present invention is not limited to the form disclosed herein, should not be regarded as excluding other embodiments, but can be used in various other combinations, modifications and environments, and can be changed within the scope of the concept described herein through the above teachings or the technology or knowledge in the relevant field. And the changes and modifications made by those skilled in the art that do not depart from the spirit and scope of the present invention should all be within the protection scope of the appended claims of the present invention.
