Description

Technical Field

[0001] This utility model relates to the field of rubber processing and production technology, specifically to a rubber breaking machine for rubber processing and production. Background Technology

[0002] Tire shredders are mainly used in the rubber recycling industry. Waste rubber blocks are crushed and sheared by the shredder's rollers into fine rubber powder particles, which can be used to manufacture recycled rubber, plastic running tracks, etc. The shredding principle of the shredder is that two rollers rotate in opposite directions, causing the rubber blocks in the gap between the rollers to be sheared and crushed.

[0003] During the shearing and extrusion process, the rubber-breaking roller generates a large amount of heat due to friction, causing the roller surface temperature to rise. This leads to the carbonization of rubber particles, which then adhere to the roller surface, reducing the sharpness of the roller's cutting edge, affecting subsequent shearing and pressing efficiency, and increasing the equipment's energy consumption. Current cooling methods primarily use hollow rollers with cooling water flowing through the central control roller. This method affects roller rigidity and weakens the roller's structural strength. Increasing the roller thickness to prevent deformation further impacts heat exchange and reduces cooling efficiency. The rubber breaker's power drive is achieved through the meshing of a power gear and a differential gear, driving the two rollers to rotate relative to each other. Therefore, a self-aligning structure is installed next to the power drive component of the rubber breaker, requiring frequent adjustments and checks of the center distance between the two gears. Existing self-aligning structures are inconvenient for maintenance and adjustment. Utility Model Content

[0004] Therefore, the technical problem to be solved by this utility model is to overcome the defects in cooling and maintenance of the existing rubber crusher, thereby providing a rubber crusher for rubber processing and production.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0006] A rubber breaking machine for rubber processing includes a base, a frame, a drive unit, and a breaking device. The frame is vertically fixed on the base, and the breaking device is mounted on the frame. The drive unit is located at one end of the breaking device and controls its rotation. The breaking device includes a breaking drive roller and a breaking driven roller that rotate relative to each other. The axes of the breaking drive roller and the breaking driven roller are parallel to each other and located at the same height. The axes of the breaking drive roller and the breaking driven roller are both arranged along the length of the base. The breaking device also includes cooling components, which are correspondingly arranged with the breaking drive roller and the breaking driven roller. Each cooling component includes an inlet / outlet assembly and a cooling channel. Both ends of the breaking driven roller are also provided with self-aligning devices that pass through the side wall of the frame. The self-aligning devices are perpendicular to the axis of the breaking driven roller.

[0007] By adopting the above technical solution, the drive device controls the relative rotation of the active and driven rubber crushing rollers and generates a speed difference, thereby tearing the rubber material and achieving the purpose of rubber crushing. During the movement of the active and driven rubber crushing rollers, a cooling component is set to cool the two rollers, avoiding local overheating that could cause rubber carbonization and adhesion. The cooling component is different from the original hollow roller cooling method, as it can be closer to the roller surface, resulting in high cooling efficiency. Furthermore, when the rollers rotate, the cooling water introduced can be closer to the heat source due to centrifugal force, ensuring sufficient cooling.

[0008] Furthermore, the driven roller for breaking rubber includes a driven roller surface and a driven roller core arranged coaxially. The driven roller surface is sleeved on the driven roller core. The diameters at both ends of the driven roller core are smaller than the diameter at the middle of the driven roller core. Driven protrusions and driven grooves are arranged in an alternating array along the outer circumference of the driven roller surface. Both the driven protrusions and driven grooves are arranged along the axial direction of the driven roller surface. The active roller for breaking rubber includes an active roller surface and an active roller core arranged coaxially. The active roller surface is sleeved on the active roller core. The diameters at both ends of the active roller core are smaller than the diameter at the middle of the active roller core. Active protrusions and active grooves are arranged in an alternating array along the outer circumference of the active roller surface. Both the active protrusions and active grooves are inclined relative to the axial direction of the active roller surface.

[0009] By adopting the above technical solution, the driven protrusion and driven groove on the rubber breaking driven roller are straight lines, while the active protrusion and active groove on the rubber breaking active roller are oblique lines. When the two mesh, the shearing force is increased, and the mutual cleaning operation of the two rollers can be achieved even without rubber material. The two rollers are forged parts, and the protrusion and groove are directly machined after being welded as a whole. As a result, the two rollers have higher hardness and longer service life compared with the existing technology.

[0010] Furthermore, both the active and driven roller cores have coaxially formed water passage holes. The cooling channel includes multiple cooling grooves and multiple water distribution channels. The cooling grooves are arranged in a circumferential array on the surfaces of the active and driven roller cores, and the length of each cooling groove is less than the length of the corresponding active and driven roller surfaces. The water distribution channels are arranged in an array along the length direction of the water passage holes, and the distance between the two ends of the water distribution channels is not greater than the length of the cooling grooves. The water distribution channels are also arranged in a circumferential array outside the water passage holes and penetrate the sidewalls of the corresponding active and driven roller cores, communicating with the water passage holes. The water distribution channels are cylindrical and their axes are arranged radially along the water passage holes. The water distribution channels are also connected to the cooling grooves.

[0011] By adopting the above technical solution, cooling water is sent into the water passage and then into multiple cooling tanks through the water distribution channel to directly cool the roller surface. The entire process does not require machine shutdown and the cooling liquid can be directly drawn out of the roller, ensuring the flow of cooling water in the rubber breaking device and effectively guaranteeing the cooling effect.

[0012] Furthermore, the water passage is also connected to the inlet / outlet assembly, which includes an inlet pipe and a drain pipe. The inlet pipe is L-shaped with its opening facing downwards and one end extending into the water passage. The bottom of the two inlet pipes is connected to a water supply pipe, and the base extends a water pipe support corresponding to the water supply pipe. The drain pipe is also L-shaped with its opening facing downwards. The drain pipe is sleeved outside the inlet pipe. One end of the drain pipe abuts against the end face of the corresponding active or driven roller core, and the other end is fixed to the outer wall of the vertical section of the inlet pipe. The horizontal side of the drain pipe has a drain outlet, and a vertically arranged outlet pipe is connected to the drain outlet. The bottom of the two outlet pipes is connected to a main outlet pipe, and the base extends a water pipe support corresponding to the main outlet pipe.

[0013] By adopting the above technical solution, the cooling water on each roller enters the water passage through the water inlet pipe and is discharged through the drain pipe. The water inlet and outlet do not affect each other and are easy to operate. The horizontal center lines of the water inlet pipe and the drain pipe are set coaxially, which is conducive to the balanced cooling inside the roller, thereby achieving the purpose of efficient cooling.

[0014] Furthermore, a first support frame and a second support frame are respectively provided at both ends of the horizontal section of the water inlet pipe located within the water passage hole. The first support frame is located in the middle of the water passage hole and is sleeved at the end of the horizontal section of the water inlet pipe. The outer wall of the first support frame abuts against the inner wall of the water passage hole. Multiple first drainage holes are provided through the first support frame, and the first drainage holes are arranged in a circumferential array along the first support frame. The second support frame is located at the end of the water passage hole, and the water passage hole also extends to provide a mounting groove for engaging the second support frame. The diameter of the second support frame is larger than that of the first support frame. Multiple second drainage holes are provided on the second support frame, and the second drainage holes are arranged in a circumferential array along the second support frame.

[0015] By adopting the above technical solution, the first support frame and the second support frame provide support for the water inlet pipe inside the water passage hole, ensuring that the horizontal section of the water inlet pipe is set horizontally without affecting the cooling water delivery, and avoiding the water inlet pipe from shifting and affecting the cooling effect.

[0016] Furthermore, the side wall of the frame is provided with mounting holes corresponding to the rubber breaking device. Both ends of the rubber breaking active roller and the rubber breaking driven roller are fitted with bearing seats, which are installed in the mounting holes. Each bearing seat includes a bearing sleeve, a thrust bearing, and two rolling mill bearings. Both ends of the active roller core and the driven roller core are provided with stepped grooves to install the thrust bearing. The two rolling mill bearings are arranged side by side and fitted on the active roller core and the driven roller core near their ends. The bearing sleeve is fitted on the thrust bearing and the two rolling mill bearings.

[0017] By adopting the above technical solution, the bearing housing provides rotational support for the rubber breaking drive roller and the rubber breaking driven roller, ensuring smooth rotation and facilitating meshing transmission between the two; the thrust bearing and the rolling mill bearing ensure stable support at the ends of the two rollers, thereby ensuring smooth rotation.

[0018] Furthermore, the bearing housings at both ends of the rubber breaking driven roller are externally connected to a self-aligning device. The self-aligning device includes a self-aligning shaft, a self-aligning end cap, and a protective plate. The self-aligning shaft is arranged perpendicular to the side wall of the bearing housing. The self-aligning end cap is installed at the end of the self-aligning shaft away from the bearing housing. The protective plate is installed between the bearing housing and the self-aligning shaft.

[0019] By adopting the above technical solution, the self-aligning device adjusts the center distance between the rubber breaking active roller and the rubber breaking driven roller to ensure that the driving component of the two - the differential gear - is in a proper meshing position. The protective plate between the self-aligning shaft and the bearing sleeve prevents the two from directly contacting each other, thereby reducing the frequency of damage and replacement of the end of the self-aligning shaft. When replacing the protective plate, you only need to remove the self-aligning end cover and take out the self-aligning shaft to directly replace the protective plate, which is low in replacement cost.

[0020] Furthermore, a dustproof device is also provided on the top of the frame. The dustproof device includes a dustproof upright plate, a support rib plate, and a dustproof baffle. The dustproof upright plate is vertically arranged at both ends of the glue-breaking device and located inside the frame. The dustproof upright plate is arranged parallel to the inner side of the frame. The support rib plate is L-shaped and arranged on the side of the dustproof upright plate that is far away from each other, and its bottom is fixed to the top surface of the frame. The dustproof baffle is installed inside the frame and is perpendicular to the side of the frame. The dustproof baffle is also perpendicular to the dustproof upright plate.

[0021] By adopting the above technical solution, the dustproof upright plate and dustproof baffle work together to reduce the splashing of rubber material to both sides and the front end during the crushing process, without affecting the discharge of rubber material from the top. The dustproof upright plate is higher than the frame, and the shielding surface is larger. The supporting ribs provide support for the dustproof upright plate to prevent it from tipping over.

[0022] In summary, the technical solution of this utility model has the following advantages:

[0023] 1. The rubber crusher for rubber processing provided by this utility model cools the surface of the rollers by setting up multiple water channels, which avoids the deterioration of the roller structure strength and has good cooling efficiency.

[0024] 2. The rubber crusher for rubber processing and production provided by this utility model has a self-aligning device that adjusts the center distance between the active crushing roller and the driven crushing roller to ensure that the driving components of the two rollers—the differential gears—are in a suitable meshing position. The protective plate between the self-aligning shaft and the bearing sleeve prevents them from directly contacting each other, thereby reducing the frequency of damage and replacement of the end of the self-aligning shaft.

[0025] 3. The rubber breaking machine for rubber processing provided by this utility model has a higher dustproof upright plate and is equipped with a dustproof baffle, resulting in better dustproof effect. Attached Figure Description

Detailed Implementation

[0034] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only for explaining the present invention and are not intended to limit the present invention.

[0035] A rubber breaking machine for rubber processing and production, such as Figure 1As shown, the device includes a base 1, two frames 2, a drive unit 3, and a rubber-breaking device 4. The frames 2 are arranged along the width direction of the base 1 and are vertically fixed to the base 1. The rubber-breaking device 4 is mounted on the frames 2. The drive unit 3 is located at the right end of the rubber-breaking device 4 and controls the rotation of the rubber-breaking device 4. The rubber-breaking device 4 includes a rubber-breaking active roller 41 and a rubber-breaking driven roller 42 that rotate relative to each other. The axes of the rubber-breaking active roller 41 and the rubber-breaking driven roller 42 are parallel to each other and located at the same height. The rubber-breaking active roller 41 is located at the rear end of the rubber-breaking driven roller 42. The axes of the rubber-breaking active roller 41 and the rubber-breaking driven roller 42 are both arranged along the length direction of the base 1. The rubber-breaking device 4 also includes a cooling component 5, which is correspondingly arranged with the rubber-breaking active roller 41 and the rubber-breaking driven roller 42. Both ends of the rubber-breaking driven roller 42 are also provided with self-aligning devices 6 that pass through the side wall of the frame 2. The self-aligning devices 6 are perpendicular to the axis of the rubber-breaking driven roller 42. The drive unit 3 controls the rubber breaking active roller 41 and the rubber breaking driven roller 42 to rotate relative to each other and generate a speed difference, thereby tearing the rubber material and achieving the purpose of rubber breaking. During the movement of the rubber breaking active roller 41 and the rubber breaking driven roller 42, a cooling component 5 is set to cool the two rollers to avoid local overheating and rubber carbonization and adhesion. The cooling component 5 is different from the original hollow roller cooling method. It can be closer to the roller surface, has high cooling efficiency, and when the roller rotates, the cooling water that is introduced can be closer to the heat source due to centrifugal force, ensuring sufficient cooling.

[0036] like Figure 1 and Figure 2 As shown, a dustproof device 7 is also installed on the top of the frame 2. The dustproof device 7 includes a dustproof upright plate 71, a support rib plate 72, and a dustproof baffle 73. The dustproof upright plate 71 is vertically installed at both ends of the rubber breaking device 4 and located inside the frame 2. The dustproof upright plate 71 is parallel to the inner side of the frame 2. The support rib plate 72 is L-shaped and installed on the side of the dustproof upright plate 71 that is far away from each other, and its bottom is fixed to the top surface of the frame 2. The dustproof baffle 73 is installed inside the frame 2 and is perpendicular to the side of the frame 2. The dustproof baffle 73 is also perpendicular to the dustproof upright plate 71. The length and width of the dustproof baffle 73 are not less than the length and width of the bottom extension seat of the frame 2. The dustproof upright plate 71 and the dustproof baffle 73 work together to reduce the splashing and overflow of rubber material to both sides and the front end during the rubber material crushing process, and do not affect the rubber material falling from the top. The dustproof upright plate 71 is higher than the frame 2, and the shielding surface is larger. The support rib plate 72 provides support for the dustproof upright plate 71 to prevent it from tipping over.

[0037] like Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, the active rubber-breaking roller 41 includes an active roller surface 411 and an active roller core 412 coaxially arranged. The active roller surface 411 is sleeved on the active roller core 412, and the diameters at both ends of the active roller core 412 are smaller than the diameter at the middle of the active roller core 412. Active protrusions 4111 and active grooves 4112 are arranged in an alternating array along the outer circumference of the active roller surface 411. Both the active protrusions 4111 and the active grooves 4112 are inclined relative to the axis of the active roller surface 411.

[0038] The driven roller 42 for breaking rubber includes a driven roller surface 421 and a driven roller core 422 arranged coaxially. The driven roller surface 421 is sleeved on the driven roller core 422. The diameters at both ends of the driven roller core 422 are smaller than the diameter at the middle of the driven roller core 422. Driven protrusions 4211 and driven grooves 4212 are arranged in an alternating array along the outer circumference of the driven roller surface 421. Both the driven protrusions 4211 and the driven grooves 4212 are arranged along the axial direction of the driven roller surface 421.

[0039] The active protrusion 4111 and active groove 4112 on the active rubber-breaking roller 41 are oblique lines, while the driven protrusion 4211 and driven groove 4212 on the driven rubber-breaking roller 42 are straight lines. When the two mesh, the shearing force is increased, and the rotation of the two rollers can also achieve mutual cleaning operation when there is no rubber material. The two rollers are forged, and the protrusions and grooves are directly machined after being integrally welded. The roller surface and roller core are formed by heat fitting. Compared with the existing technology, the two rollers have higher hardness and longer service life.

[0040] like Figure 1 , Figure 2 and Figure 3 As shown, each cooling component 5 includes an inlet / outlet assembly 51 and a cooling channel 52.

[0041] Both the driving roller core 412 and the driven roller core 422 have water passage holes 43 coaxially formed inside them. The cooling channel 52 includes multiple cooling grooves 521 and multiple water distribution channels 522. The cooling grooves 521 are arranged in a circumferential array on the surfaces of the active roller core 412 and the driven roller core 422, respectively. The length of each cooling groove 521 is less than the length of the corresponding active roller surface 411 and the driven roller surface 421. The water distribution channels 522 are arranged in an array along the length direction of the water passage hole 43, and the distance between the two ends of the water distribution channels 522 is not greater than the length of the cooling grooves 521. The water distribution channels 522 are also arranged in a circumferential array outside the water passage hole 43 and penetrate through the sidewalls of the corresponding active roller core 412 and the driven roller core 422 and communicate with the water passage hole 43. The water distribution channels 522 are cylindrical and their axes are arranged radially along the water passage hole 43. The water distribution channels 522 are also connected to the cooling grooves 521. In this embodiment, two groups of water distribution channels 522 are provided, and the latter group of water distribution channels 522 has a certain angle of rotation compared to the former group.

[0042] The water passage 43 is also connected to the inlet / outlet assembly 51, which includes an inlet pipe 511 and a drain pipe 512, as well as an outer protective cover 513. The outer protective cover 513 is located outside the frame 2 and covers the left end of the rubber breaking drive roller 41 and the rubber breaking driven roller 42. The inlet pipe 511 is L-shaped with its opening facing downward and one end extending into the water passage 43. The bottom of the two inlet pipes 511 is connected to a water delivery pipe 5113, which is perpendicular to the vertical side of the inlet pipe 511. A water pipe support 11 extends from the base 1 corresponding to the water delivery pipe 5113. The drainage pipe 512 is also L-shaped with the opening facing downwards. The upper part of the drainage pipe 512 is sleeved outside the water inlet pipe 511. One end of the drainage pipe 512 abuts against the end face of the corresponding active roller core 412 or driven roller core 422, and the other end is fixed to the outer wall of the vertical section of the water inlet pipe 511. A drainage port 5121 is opened below the horizontal side of the drainage pipe 512. A vertically arranged water outlet pipe 5122 is connected to the drainage port 5121. The bottom of the two water outlet pipes 5122 is connected to a main outlet pipe 5123. The main outlet pipe 5123 is perpendicular to the water outlet pipes 5122. A water pipe support 11 extends from the base 1 corresponding to the main outlet pipe 5123. Cooling water on each roller enters the water passage 43 through the water inlet pipe 511 and is discharged through the drain pipe 512. The water inlet and outlet do not affect each other and are easy to operate. The horizontal center lines of the water inlet pipe 511 and the drain pipe 512 are set coaxially, which is conducive to the balanced cooling inside the roller, thereby achieving the purpose of efficient cooling.

[0043] like Figure 3 As shown, a first support frame 5111 and a second support frame 5112 are respectively provided at both ends of the horizontal section of the water inlet pipe 511 located within the water passage hole 43. The first support frame 5111 is located near the middle of the water passage hole 43 and is sleeved at the end of the horizontal section of the water inlet pipe 511. The outer wall of the first support frame 5111 abuts against the inner wall of the water passage hole 43. Multiple first drain holes 51111 are provided through the first support frame 5111, and the first drain holes 51111 are arranged in a circumferential array along the first support frame 5111. The second support frame 5112 is located near the end of the water passage hole 43, and the water passage hole 43 also extends a mounting groove 431 to engage the second support frame 5112. The diameter of the second support frame 5112 is larger than that of the first support frame 5111. Multiple second drain holes 51121 are provided on the second support frame 5112, and the second drain holes 51121 are arranged in a circumferential array along the second support frame 5112. The first support frame 5111 and the second support frame 5112 provide support for the water inlet pipe 511 inside the water passage hole 43. The first support frame 5111 and the second support frame 5112 are respectively provided with a first drain hole 51111 and a second drain hole 51121, which ensures that the horizontal section of the water inlet pipe 511 is set horizontally without affecting the cooling water supply and avoids the water inlet pipe 511 from shifting and affecting the cooling effect.

[0044] like Figure 1 , Figure 3 and Figure 5 As shown, the side wall of the frame 2 has mounting holes 21 corresponding to the rubber breaking device 4. Both ends of the rubber breaking drive roller 41 and the rubber breaking driven roller 42 are fitted with bearing seats 22, which are installed in the mounting holes 21. Each bearing seat 22 includes a bearing sleeve 221, a thrust bearing 222, and two rolling mill bearings 223. Both ends of the drive roller core 412 and the driven roller core 422 have stepped grooves 224 for mounting the thrust bearing 222. The two rolling mill bearings 223 are arranged side by side and fitted on the drive roller core 412 and the driven roller core 422 near their ends. The inner diameter of the rolling mill bearing 223 is smaller than the inner diameter of the thrust bearing 222. The bearing sleeve 221 is fitted on the outside of the thrust bearing 222 and the two rolling mill bearings 223.

[0045] like Figure 1 and Figure 5 As shown, a self-aligning device 6 is externally connected to the bearing housings 22 at both ends of the rubber-breaking driven roller 42. The self-aligning device 6 includes a self-aligning shaft 61, a self-aligning end cap 62, and a protective plate 63. The self-aligning shaft 61 is set perpendicular to the side wall of the bearing housing 22. The self-aligning end cap 62 is installed at the end of the self-aligning shaft 61 away from the bearing housing 22. The protective plate 63 is installed between the bearing housing 22 and the self-aligning shaft 61. The self-aligning device 6 adjusts the center distance between the rubber-breaking drive roller 41 and the rubber-breaking driven roller 42 to ensure that the driving component - the differential gear - of the two is in a proper meshing position. The protective plate 63 is between the self-aligning shaft 61 and the bearing sleeve 221 to prevent the two from directly contacting each other, thereby reducing the frequency of replacement of the end of the self-aligning shaft 61 due to damage. When replacing the protective plate 63, it is only necessary to directly remove the self-aligning end cap 62 and take out the self-aligning shaft 61 to directly replace the protective plate 63, which has low replacement cost.

[0046] The working principle and usage of this rubber processing and production rubber breaking machine are as follows: A rubber breaking active roller 41 and a rubber breaking driven roller 42 are produced, and corresponding active grooves 4112 and driven grooves 4212 are machined on their surfaces, thus highlighting the active protrusions 4111 and driven protrusions 4211; the active roller surface 411 and active roller core 412, and the driven roller surface 421 and driven roller core 422 are formed by heat fitting to constitute the rubber breaking active roller 41 and rubber breaking driven roller 42; the rubber breaking active roller 41 and rubber breaking driven roller 42 are then installed on the frame 2 and connected to the cooling component 5; dustproof upright plates 71 are inserted and installed at both ends of the rubber breaking active roller 41 and rubber breaking driven roller 42, and the dustproof upright plates 71 are fixed by support ribs 72; a dustproof baffle 73 is also installed on the frame 2.
