[0031] The present application will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, only the parts relevant to the invention are shown in the accompanying drawings.

[0032] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0033] Please refer to Figure 1 This application provides a cutting device for rubber and plastic products with dual-wheel adaptive grinding, comprising:

[0034] A front-stage conveyor belt 1 and a rear-stage conveyor belt 2 are provided. Both the front-stage conveyor belt 1 and the rear-stage conveyor belt 2 are conveyed along a first direction and their bearing surfaces are parallel. A cutting space is provided between the front-stage conveyor belt 1 and the rear-stage conveyor belt 2.

[0035] A cutting assembly, comprising a cutting blade 3, which is mounted above the cutting space and is movable along a second direction, which is parallel to the bearing surface and perpendicular to the first direction.

[0036] A transition component, disposed within the cutting space, is used to support materials passing through the cutting space;

[0037] A polishing assembly includes two polishing units arranged along the first direction. The two polishing units are located on the same side of the front conveyor belt 1 and the rear conveyor belt 2, and are respectively located on opposite sides of the transition assembly.

[0038] Specifically, the front conveyor belt 1 and the rear conveyor belt 2 are two independent conveyor belts. The bearing surface of the front conveyor belt 1 is its top surface, and the bearing surface of the rear conveyor belt 2 is also its top surface. The bearing surfaces of the front conveyor belt 1 and the rear conveyor belt 2 are on the same plane, and both the front conveyor belt 1 and the rear conveyor belt 2 convey along a first direction. In this embodiment, the first direction is a horizontal direction. A cutting space is formed between the rear end of the front conveyor belt 1 and the front end of the rear conveyor belt 2. During the conveying process, the material is cut at the cutting space to obtain materials of different sizes. The cutting of the material is achieved by a cutting assembly, which includes at least one cutting blade 3. The cutting blade 3 is suspended above the cutting space and can rotate about an axis along the first direction. The cutting blade 3 cuts the material by contacting it. Moreover, the cutting blade 3 can move along a second direction, and the cutting position can be flexibly adjusted by moving it, thereby adapting to the transverse cutting of materials of different widths. In this embodiment, the second direction is a horizontal direction and perpendicular to the first direction. To prevent materials from sagging or shifting due to lack of support when they are conveyed to the cutting space, a transition component is also provided in the cutting space. The transition component can ensure the stability of the material when it transitions from the front conveyor belt 1 to the rear conveyor belt 2, and can also support the material when the cutting blade 3 cuts the material to prevent the material from sagging or shifting, thereby ensuring cutting accuracy.

[0039] To enable timely sharpening of the cutting blade 3, this application also includes a sharpening assembly consisting of two sharpening units located on the same side of the conveyor belt. When the cutting blade 3 moves to the sharpening position, the two sharpening units sharpen the cutting blade 3 from both sides. The sharpening process does not require disassembling the blade, which saves time on disassembly and installation, restores the blade's sharpness in a timely manner, ensures cutting quality, and improves the processing efficiency and practicality of the equipment.

[0040] Furthermore, the cutting assembly includes:

[0041] Support frame 4, which is mounted above the front conveyor belt 1;

[0042] The movable slide rail 5 is fixed on the support frame 4 and extends along the second direction;

[0043] A movable seat 6 is slidably mounted on the movable slide rail 5. A fixed plate 7 is mounted on the movable seat 6, and the cutting blade 3 is rotatably mounted on the fixed plate 7.

[0044] The first driving device 8 is mounted on the fixed plate 7 and is used to drive the cutting blade 3 to rotate.

[0045] Specifically, the two ends of the support frame 4 are fixed to both sides of the conveyor belt, and the top of the support frame 4 is suspended above the front conveyor belt 1. A movable slide rail 5 is provided on the side of the top of the support frame 4 near the rear conveyor belt 2. The movable slide rail 5 is fixed to the support frame 4 and extends along the second direction. The movable seat 6 is engaged with the movable slide rail 5 and can slide automatically along the movable slide rail 5. The movable seat 6 is driven by a conventional drive mechanism. The specific structure of the drive mechanism is not shown in the attached figure. Optionally, the drive mechanism is a servo motor with a lead screw or a transmission belt. A fixing plate 7 is installed on the side of the movable seat 6 near the rear conveyor belt 2. The fixing plate 7 extends downward and is provided with a first drive device 8 and a cutting blade 3 at the bottom end. The first drive device 8 is installed on the side of the fixing plate 7 away from the rear conveyor belt 2, and the cutting blade 3 is rotatably installed on the side of the fixing plate 7 near the rear conveyor belt 2. The cutting blade 3 is connected to the output shaft of the first drive device 8. Optionally, the first drive device 8 is a motor.

[0046] Furthermore, the fixing plate 7 is provided with a protective cover 9, which is sleeved on the outside of the cutting blade 3, and the protective cover 9 is provided with an avoidance notch 10 on the side of the protective cover 9 near the grinding unit.

[0047] Specifically, the protective cover 9 is installed on the side of the fixed plate 7 near the rear conveyor belt 2, and the protective cover 9 is connected to the fixed plate 7 by bolts. The protective cover 9 covers the cutting blade 3, providing safety protection for the high-speed rotating cutting blade 3, preventing operators from accidentally contacting the blade, and blocking material debris from flying during the cutting process, thus improving the safety of equipment use. By setting a clearance notch 10 on the protective cover 9, the two grinding units can remove the cutting blade 3 for grinding operations without disassembling the protective cover 9, thus preserving the protective function of the protective cover 9 while ensuring the feasibility of the grinding operation.

[0048] Furthermore, the transition component includes:

[0049] The support base 11 is hollow inside and has a relief groove 12 communicating with the interior on its top surface; the relief groove 12 extends along the second direction and is used to avoid the cutting blade 3.

[0050] The receiving plate 13 is fixed to the top surface of the support base 11 and is used to support materials; the receiving plate 13 is provided with a through opening 14 corresponding to the clearance groove 12, and the through opening 14 extends along the second direction.

[0051] Specifically, the support base 11 is a square steel tube structure, hollow inside and connected at both ends, effectively reducing its own weight. The support base 11 extends along the second direction and is placed between the front conveyor belt 1 and the rear conveyor belt 2, with the end of the support base 11 near the two grinding units extending outward. A clearance groove 12 is provided on the top surface of the support base 11. The clearance groove 12 is a rectangular groove that penetrates the top surface of the support base 11. When the cutting blade 3 moves horizontally, the bottom of the cutting blade 3 moves within the clearance groove 12. The receiving plate 13 is fixed to the top surface of the support base 11. The top surface of the receiving plate 13 is on the same plane as the bearing surfaces of the front conveyor belt 1 and the rear conveyor belt 2. The receiving plate 13 extends horizontally, and its width is slightly smaller than the distance between the bearing surfaces of the front conveyor belt 1 and the rear conveyor belt 2. The receiving plate 13 is used to support the material, preventing the material from sagging or deforming due to lack of support when passing through the cutting space, effectively ensuring cutting accuracy. The through-hole 14 on the receiving plate 13 corresponding to the clearance groove 12 forms a through structure with the clearance groove 12. On the one hand, it allows the cutting blade 3 to cut into the material through the through-hole 14, and on the other hand, it ensures that the support base 11 does not obstruct the movement of the cutting blade 3.

[0052] Furthermore, the polishing unit includes:

[0053] Mounting base 15, the top of the mounting base 15 is provided with a guide rail 16, the guide rail 16 extends along the first direction;

[0054] A sliding seat 17 is disposed on the top of the mounting base 15 and slidably connected to the guide rail 16. A second driving device 18 is mounted on the sliding seat 17. The rotation shaft of the second driving device 18 extends along the first direction and a grinding wheel 19 is mounted at its end.

[0055] The third driving device 20 is used to drive the sliding seat 17 to move along the guide rail 16.

[0056] Specifically, the mounting base 15 can be fixed to the frame of the conveyor belt. A guide rail 16 is provided at the center of the top of the mounting base 15, and the guide rail 16 extends along a first direction. The sliding seat 17 is slidably mounted on the top of the mounting base 15 and cooperates with the guide rail 16 to improve the smoothness of the sliding process, while restricting the movement direction of the sliding seat 17. The movement of the sliding seat 17 is driven by a third drive device 20, which is fixed to the top surface of the mounting base 15. The third drive device 20 has a retractable free end, and the sliding seat 17 is connected to the free end of the third drive device 20. Optionally, the third drive device 20 is a cylinder, and the piston rod of the third drive device 20 is retractable along the first direction. A second drive device 18 is fixed on the sliding seat 17. A grinding wheel 19 is mounted on the rotating shaft of the second drive device 18. The grinding wheel 19 is a grinding wheel, and the second drive device 18 is used to drive the grinding wheel 19 to rotate. Optionally, the second drive device 18 is a motor.

[0057] The guide rail 16 and the sliding seat 17 form a support structure that can move along the first direction, so that the grinding wheel 19 can be accurately aligned with the position to be ground on the cutting blade 3, ensuring the positioning accuracy of the grinding operation; the second drive device 18 drives the grinding wheel 19 to rotate at high speed through the rotating shaft, providing sufficient kinetic energy for the blade grinding, which can effectively remove wear marks on the surface of the cutting blade 3 and restore the sharpness of the blade; the third drive device 20 drives the sliding seat 17 to move along the guide rail 16, avoiding the randomness of manual operation and improving the uniformity and efficiency of grinding.

[0058] Furthermore, an abutment plate 21 is fixed to one end of the top surface of the mounting base 15 near the support base 11, and an elastic buffer 22 is provided between the abutment plate 21 and the sliding base 17. The elastic buffer 22 is retractable along the first direction.

[0059] Specifically, multiple elastic buffers 22 are provided between the abutment plate 21 and the sliding seat 17, and the multiple elastic buffers 22 are evenly arranged along the second direction; when the piston rod of the third drive device 20 retracts, the elastic buffer 22 is in a natural state; when the piston rod of the third drive device 20 extends, the elastic buffer 22 is compressed. Optionally, the elastic buffer 22 is a spring.

[0060] The elastic buffer 22 is designed to absorb the impact energy of the sliding seat 17 when it moves along the guide rail 16 to its limit position near the support seat 11, preventing the sliding seat 17 from colliding hard with the abutment plate 21. This protects the installation structure and drive device of the grinding unit, reduces wear and damage to mechanical parts, and extends the service life of the equipment. At the same time, the elastic support characteristics of the elastic buffer 22 allow the grinding wheel 19 to maintain dynamic buffer pressure when it contacts the cutting blade 3, preventing damage to the blade due to excessive grinding pressure or affecting the grinding effect due to insufficient pressure. This ensures uniform and stable pressure during the grinding process and improves grinding accuracy. In addition, the elastic buffer 22 can effectively absorb the vibration energy during equipment movement, reduce the swaying amplitude of the grinding unit, and keep the base position of the grinding wheel 19 and the cutting blade 3 accurate, further ensuring the consistency and reliability of the grinding operation.

[0061] Furthermore, the sliding seat 17 is provided with a locking seat 23, which is used to position the second driving device 18.

[0062] Specifically, the locking bracket 23 is used to position the end of the second drive device 18 away from its rotation axis. The precise positioning of the second drive device 18 by the locking bracket 23 ensures the coaxiality of the rotation axis of the second drive device 18 with the grinding wheel 19 during installation, preventing eccentric rotation of the grinding wheel 19 due to installation deviations. This ensures the uniformity and stability of the grinding operation. Simultaneously, it prevents displacement or loosening of the second drive device 18 during high-speed rotation or movement of the sliding seat 17, avoiding impacts on grinding accuracy or even equipment malfunction due to positional deviations of the second drive device 18.

[0063] Furthermore, each of the grinding units includes two of the third driving devices 20, which are arranged along the second direction and distributed on both sides of the sliding seat 17.

[0064] Specifically, by symmetrically arranging two third drive devices 20 on both sides of the sliding seat 17, a bidirectional synchronous drive structure can be formed, avoiding the sliding seat 17 from tilting or getting stuck on the guide rail 16 due to uneven force on a single drive device, and ensuring the stability and straightness of the sliding seat 17 when moving along the first direction; the third drive devices 20 on both sides can provide double the driving torque by working together, enhancing the driving capability of the sliding seat 17 and avoiding the decrease in grinding efficiency due to insufficient driving force.

[0065] Furthermore, the support frame 4 is also provided with a limiting block 24, which is located at both ends of the movable slide rail 5.

[0066] Specifically, the limiting block 24 is fixed on the support frame 4. The limiting block 24 is used to precisely limit the sliding stroke of the moving seat 6 on the moving slide rail 5, so as to prevent the cutting blade 3 from exceeding the preset range when moving in the second direction, avoid the cutting blade 3 from colliding with other parts of the equipment or causing structural damage due to excessive movement, and ensure the safety of the movement of the cutting component.

[0067] The above description is merely a preferred embodiment of this application and an explanation of the technical principles employed.
