Description

Technical Field

[0001] The invention relates to the technical field of rubber crushing, in particular to waste rubber cracking and crushing processing equipment. Background Art

[0002] Tires are consumables. After a period of use, the tread pattern on the tire surface gradually becomes shallower due to wear. Therefore, tires need to be replaced regularly to ensure driving safety. In order to increase the reuse rate of rubber and reduce resource waste, waste tires are currently being recycled and processed in a centralized manner. The recycled waste tires are then crushed and converted into rubber pellets. In existing waste tire recycling, the steel wire is generally extracted first, and then the strip tire rubber is cut into blocks by a primary crusher. The blocks are then added to a secondary crusher to crush the rubber into particles. Existing secondary crushers generally crush the rubber using crushing rollers or high-speed rotating crushing blades. However, due to the high elasticity of rubber itself, the degree of uniformity after crushing is not high. As a result, when rubber pellets of a certain specification need to be formed, the crushed material is often screened through a sieve. Moreover, due to the low uniformity, the waste is relatively high. Summary of the Invention

[0011] Furthermore, the outer side wall of the conical screen is in a truncated cone shape, the top of the conical screen converges toward the middle, and a vent hole is provided at the top of the conical screen, and the vent hole is used to avoid interference with the transmission shaft.

[0012] Furthermore, three annular frames are evenly connected to the inner wall of the conical screen, and a plurality of positioning blocks are evenly connected to the bottom surface of the lowest annular frame. A plurality of positioning holes are evenly opened in an annular manner on the inner bottom surface of the outer shell, and the plurality of positioning holes correspond to the plurality of positioning blocks.

[0013] Furthermore, the execution module includes a second transmission sleeve, which is used for slidingly connecting with the edge rod portion of the transmission shaft. The outer wall of the second transmission sleeve is fixedly connected with a mounting bracket, one end of the mounting bracket is fixedly connected with an arc-shaped blade, one end of the arc-shaped blade is provided with a cutting edge, and one end side wall of the arc-shaped blade is fixedly connected with a guide plate.

[0014] Furthermore, a transmission sleeve 1 is provided in the middle position of the tile ring, and the transmission sleeve 1 is slidably connected to the edge rod portion of the transmission shaft. The inclination of the outer wall of the bottom end of the tile ring is the same as the inclination of the conical screen. The outer diameter of the bottom end of the tile ring is larger than the outer diameter of the bottom end of the conical screen. An eccentric frame is fixedly connected between the transmission sleeve 1 and the tile ring, and the transmission sleeve 1 and the tile ring are in an eccentric state.

[0015] Furthermore, an intermediate chamber is formed between the tile ring and the conical screen, and an inclined push frame is fixedly connected to the inner wall of the tile ring at a side away from the transmission sleeve.

[0016] Furthermore, the sizes of the sieve holes on the plurality of conical screens decrease from top to bottom, and the distance between two adjacent conical screens in the plurality of conical screens is staggered by 180 degrees.

[0017] Furthermore, fixed sleeves are fixedly connected to both sides of the outer wall of the shell component, and the fixed sleeves are used for sliding sleeve connection with the positioning pin shaft, and the sum of the heights of the second transmission sleeve and the first transmission sleeve is the same as the height of the fixed sleeve.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] 1. Through the setting of the crushing unit, the transmission shaft drives the execution module and the tile ring to rotate synchronously. After the material falls between the tile ring and the conical screen, the material is squeezed toward the conical screen through the rotation of the tile ring, so that part of the block material passes through the sieve holes on the conical screen to the inner side of the conical screen. When the execution module rotates, the part of the material that passes through the conical screen is cut, thereby realizing cyclic cutting and crushing of the material. The crushing unit at the top performs primary crushing on the material, and the crushed material enters the crushing unit in the middle position for secondary crushing. Finally, after the third crushing by the crushing unit at the bottom, the material falls into the receiving bucket and is discharged. This device utilizes the elasticity of the waste rubber itself to circulate and squeeze the material through the tile ring, and cuts the part protruding to the inner side of the conical screen, thereby realizing multiple crushing of the block material, and the size of the cut part of the material each time is relatively uniform, and reduces the avoidance of the material when the execution module cuts, thereby improving the crushing effect and uniformity of the waste rubber;

[0021] 2. Through the arrangement of the tile ring and the inclined push frame, the tile ring is in an eccentric state relative to the transmission sleeve 1, so that the tile ring and the conical screen are in an eccentric state, so that the gap between the side of the tile ring away from the transmission sleeve 1 and the conical screen is larger, and the gap between the other side of the tile ring close to the transmission sleeve 1 and the conical screen is smaller. The arc blade is aligned with the other side of the tile ring. When the tile ring rotates, it drives the material to be squeezed toward the conical screen. When the material is at the narrowest part of the middle chamber, the execution module cuts the material, and then the tile ring gradually relaxes its squeezing of the material. Through the arrangement of the inclined push frame The material in the middle chamber is cyclically extruded and relaxed by the ring tile. The material posture is continuously adjusted instead of being extruded continuously, so that part of the material can pass through the conical screen and be extruded, which is convenient for the material to pass through the conical screen.

DETAILED DESCRIPTION

[0032] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0033] See also Figures 1 to 8In an embodiment of the present invention, a waste rubber cracking and crushing processing equipment includes a base 100, a lower hopper 200, a crushing unit 300 and a receiving hopper 400. Positioning pins 130 are fixedly installed on both sides of the base 100. A transmission shaft 120 is rotatably connected to the top of the base 100. A driving motor 110 is installed on the top surface of the base 100. The output end of the driving motor 110 is rotatably connected to the bottom end of the transmission shaft 120. There are three crushing units 300, which are stacked in sequence between two positioning pins 130. The crushing unit 300 includes a tile ring 310, an outer The shell 320, the conical screen 330 and the execution module 340, the tile ring 310, the execution module 340 and the drive shaft 120 are slidably plugged in, the outer shell 320 and the two positioning pin shafts 130 are slidably plugged in, the lower hopper 200 is located above the three crushing units 300, the lower hopper 200 is used to introduce the material into the crushing unit 300, the receiving bucket 400 is located below the three crushing units 300, the receiving bucket 400 is installed between the two positioning pin shafts 130, and one side of the receiving bucket 400 is fixedly connected to the discharge port 410, and the receiving bucket 400 is used to receive and discharge the processed material.

[0034] Specifically, the driving motor 110 drives the transmission shaft 120 to rotate, and the transmission shaft 120 drives the execution module 340 and the tile ring 310 to rotate synchronously. The material is added from the lower hopper 200 to the top of the crushing unit 300, and the material falls between the tile ring 310 and the conical screen 330. The rotation of the tile ring 310 squeezes the material toward the conical screen 330, so that part of the block material passes through the sieve holes on the conical screen 330 to the inner side of the conical screen 330.

[0035] Example 1

[0036] like Figures 3 to 9As shown, in this embodiment, the middle position of the transmission shaft 120 is a ribbed rod portion, a step is provided between the ribbed rod portion of the transmission shaft 120 and the bottom end of the transmission shaft 120, a threaded groove is provided on the top outer wall of the transmission shaft 120, and a nut is screwed into the top end of the transmission shaft 120. The outer wall of the conical screen 330 is a frustum, and the top end of the conical screen 330 converges toward the middle, and a vent hole is provided on the top end of the conical screen 330. The vent hole is used to separate the interference with the transmission shaft 120, and the inner wall of the conical screen 330 is equidistantly connected with three annular skeletons 331, which are connected by the annular skeletons. The frame 331 supports the conical screen 330, improves the strength of the conical screen 330, and reduces the deformation of the conical screen 330 caused by the tile ring 310 when the material is squeezed. The bottom surface of the annular frame 331 at the bottom is evenly connected with a plurality of positioning blocks 332. The inner bottom surface of the outer shell 320 is annularly and evenly opened with a plurality of positioning holes 321. The plurality of positioning holes 321 correspond to the plurality of positioning blocks 332. Through the arrangement of the positioning blocks 332 and the positioning holes 321, it is convenient to snap the conical screen 330 onto the outer shell 320, so that the conical screen 330 and the outer shell 320 can be conveniently connected. 20 can be detachably connected, and at the same time, the material is prevented from rubbing the conical screen 330 to rotate, which facilitates the rotation of the tile ring 310 relative to the conical screen 330. The execution module 340 includes a transmission sleeve 2 341, and the transmission sleeve 2 341 is used to slide with the ridge rod portion of the transmission shaft 120. The outer wall of the transmission sleeve 2 341 is fixedly connected with a mounting bracket 342, and one end of the mounting bracket 342 is fixedly connected with an arc-shaped blade 343, and one end of the arc-shaped blade 343 is provided with a cutting portion. The side wall of one end of the arc-shaped blade 343 is fixedly connected with a guide plate 344. The middle position of the tile ring 310 is provided with a transmission sleeve 341. 12. The transmission sleeve 312 is slidably connected to the ridge portion of the transmission shaft 120. The inclination of the outer wall of the bottom end of the tile ring 310 is the same as the inclination of the conical screen 330. The outer diameter of the bottom end of the tile ring 310 is larger than the outer diameter of the bottom end of the conical screen 330. An eccentric frame 313 is fixedly connected between the transmission sleeve 312 and the tile ring 310. The transmission sleeve 312 and the tile ring 310 are in an eccentric state. An intermediate chamber 350 is formed between the tile ring 310 and the conical screen 330. The inner wall of the tile ring 310 is fixedly connected to an inclined push frame 311 on the side away from the transmission sleeve 312.

[0037] In this embodiment, when the transmission shaft 120 rotates, it drives the transmission sleeve 2 341 and the transmission sleeve 1 312 to rotate. The transmission sleeve 2 341 drives the two arc-shaped blades 343 to revolve, and the transmission sleeve 1 312 drives the tile ring 310 to rotate. Since the tile ring 310 is in an eccentric state relative to the transmission sleeve 1 312, the tile ring 310 and the conical screen 330 are in an eccentric state, so that the gap between the side of the tile ring 310 away from the transmission sleeve 1 312 and the conical screen 330 is larger, and the tile ring 310 The gap between the other side of the transmission sleeve 312 and the conical screen 330 is small, and the arc-shaped blade 343 is aligned with the other side of the tile ring 310. When the tile ring 310 rotates, it drives the material to be squeezed toward the conical screen 330. When the material is at the narrowest part of the middle chamber 350, the execution module 340 cuts the material, and then the tile ring 310 gradually relaxes the squeezing of the material. The inclined push frame 311 is set to scrape and push the relaxed squeezed material, and the material stuck on the screen hole of the conical screen 330 is removed. The block is separated from the conical screen 330, which is convenient for subsequent posture adjustment and re-extrusion of the material block, and convenient for the other parts of the material block to pass through the sieve holes on the conical screen 330. Through the eccentric setting of the tile ring 310 and the revolution of the tile ring 310, the material in the middle chamber 350 is cyclically squeezed and relaxed. Combined with the continuous stirring of the material in the middle chamber 350 by the tile ring 310, the material is cut by the arc blade 343, and the cut material is diverted by the setting of the guide plate 344. , which facilitates guiding the cut material to fall into the covering range of the top of the tile ring 310 at the lower position, thereby facilitating the introduction of the material into the intermediate chamber 350 below. Through the detachable connection between the conical screen 330 and the outer shell 320, it is convenient to replace the conical screen 330 with different mesh sizes as needed. When replacing, loosen and remove the nut at the top of the drive shaft 120, thereby removing the tile ring 310 and the outer shell 320 above the target conical screen 330, and then replace the target conical screen 330.

[0038] Example 2

[0039] On the basis of the first embodiment, in order to facilitate the material in the first embodiment to pass through the multiple crushing units 300 from top to bottom, the material is prevented from falling between the shoe ring 310 and the outer shell 320, so as to enhance the crushing effect of the material.

[0040] like Figures 3 to 7As shown, in this embodiment, the size of the sieve holes on the multiple conical screens 330 decreases from top to bottom, and the distance between two adjacent conical screens 330 in the multiple conical screens 330 is staggered by one hundred and eighty degrees. Fixed sleeves 322 are fixedly connected to both sides of the outer wall of the outer shell 320, and the fixed sleeves 322 are used for sliding connection with the positioning pin shaft 130. The sum of the heights of the transmission sleeve 2 341 and the transmission sleeve 1 312 is the same as the height of the fixed sleeve 322. The top of the tile ring 310 located at the uppermost position among the three crushing units 300 is fixedly connected to the horizontal ring plate 314, and the bottom end of the lower hopper 200 is in contact with the top surface of the horizontal ring plate 314.

[0041] During specific implementation, by staggering two adjacent conical screens 330 by 180 degrees, the edge of the arc blade 343 corresponds to one side of the lower tile ring 310, which facilitates the lower tile ring 310 to receive the falling material. By setting multiple conical screens 330, it is convenient to crush the material from top to bottom, thereby improving the uniformity of material crushing. By setting the height of the fixed sleeve 322, the transmission sleeve 2 341 and the transmission sleeve 1 312, while the multiple fixed sleeves 322 are squeezed up and down, the multiple transmission sleeves 2 341 and the transmission sleeve 1 312 are stacked and squeezed up and down, so that the height of the tile ring 310 is supported by the transmission sleeve 1 312, avoiding tight pressure between the tile ring 310 and the outer shell 320, thereby facilitating the rotation of the tile ring 310.

[0042] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the invention can be embodied in other specific forms without departing from the spirit or essential characteristics of the invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the invention is defined by the appended claims, not the foregoing description, and all variations within the meaning and range of equivalents of the claims are intended to be included therein.
