Description

Technical Field

[0001] This utility model relates to the technical field of rubber production equipment, and in particular to a slitting machine for rubber production. Background Technology

[0002] In modern industrial systems, rubber, plastics, and other rubber compounds are indispensable basic materials, widely used in automobile manufacturing, electronics, building materials, and other fields. As the core equipment for rubber compound molding and processing, rubber compound granulation equipment undertakes the key task of slitting rubbery raw materials into precisely sized granules. Its processing quality directly affects the finished product quality and production efficiency of downstream processes such as injection molding and extrusion molding. With the continuous increase in the requirements of various industries for the refinement and high performance of rubber compound products, as well as the demand for cost reduction and efficiency improvement brought about by intensified market competition, the inherent defects of traditional rubber compound strip slitting equipment are becoming increasingly prominent.

[0003] Currently, mainstream slitting equipment on the market often results in uneven cutting of rubber strips due to the strips shifting during forward transport. This leads to uneven slitting by the cutter, affecting subsequent granulation. Furthermore, the cutter blades wear down over time, making it impossible to completely cut and separate the rubber strips. Existing slitting equipment is inconvenient to adjust, requiring blade replacement, which shortens the blade's lifespan, wastes resources, and increases costs.

[0004] Therefore, it is necessary to provide a slitting machine for rubber production to solve the above-mentioned technical problems. Utility Model Content

[0007] As a preferred technical solution of this utility model, the slitting mechanism includes multiple cutters and multiple limiting blocks. The cutter is an annular cutter. The multiple limiting blocks are evenly fixed on the outer circumferential surface of the rotating shaft. The multiple cutters and the multiple limiting blocks are staggered. The sidewall of the cutter is disposed on the sidewall of the limiting block.

[0008] As a preferred embodiment of this utility model, the slide groove is located directly above the mounting hole, the top of the snap connector is set at the bottom of the stud, a bearing is set in the mounting hole, the two ends of the feeding roller are respectively rotatably set in the two bearings, the upper surface of the feeding roller is flush with the feeding plate, and a handle is set on the rotating wheel.

The threaded part of the threaded knob passes through the adjustment column and is screwed into the threaded hole of the slider.

[0010] As a preferred technical solution of this utility model, one end of the feeding plate extends into the middle of the two mounting blocks, and four second adjustment holes are provided on the feeding plate. The second adjustment holes are elongated holes. Two locking holes are provided on the adjustment blocks. The two locking holes are respectively opened opposite the two second adjustment holes, and the corners of the two adjustment blocks opposite each other are rounded.

[0011] As a preferred technical solution of this utility model, universal wheels are provided at the four corners of the bottom of the frame.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] This utility model discloses a slitting machine for rubber production. The machine uses a power mechanism to drive a chain-driven feeding roller and a feeding rubber roller to rotate. Adjusting columns move on an adjusting plate, and the distance between the two adjusting columns is adjusted according to the scale on the adjusting plate. When the column reaches the set distance, a threaded knob is turned to lock it in place, thus limiting the width of the rubber strip. Simultaneously, the distance between the two adjusting blocks is adjusted to match the distance between the two adjusting columns, guiding the rubber strip and preventing it from shifting during forward transport, which would affect the accuracy of subsequent slitting. The rubber strip is then passed sequentially between the two adjusting columns and the two adjusting blocks. Between blocks, the rubber strips are smoothly conveyed forward by the feeding roller and the feed drum. At the same time, the start motor drives the slitting mechanism to rotate. Multiple equally spaced cutters slit the rubber strips, ensuring precise and reliable slitting with high efficiency. After prolonged use, the cutters wear down, increasing the distance between them and the feeding roller, which may prevent the rubber strips from being completely cut off. Turning the handle rotates the wheel and stud, pushing the sliding block down the groove, bringing the cutters closer to the outer circumference of the feeding roller, thus ensuring that the cutters completely cut the rubber strips. This eliminates the need for direct cutter replacement, making adjustments convenient and quick, effectively extending the cutter's lifespan and reducing costs. Attached Figure Description

[0025] The embodiments of this utility model will now be described with reference to the accompanying drawings. In this process, to ensure clarity and convenience, we may exaggerate the width of lines or the size of constituent elements in the drawings.

[0026] Furthermore, the terms used below are defined based on the functions of this utility model and may vary depending on the user's or operator's intent or convention. Therefore, these terms are defined based on the entire contents of this specification.

[0027] like Figures 1 to 6As shown, a slitting machine for rubber production includes a frame 1 and mounting blocks 4. Two mounting blocks 4 are provided, arranged parallel to each other at both ends of the top of the frame 1. First sealing plates 2 are provided on both sides of the frame 1, each with multiple heat dissipation holes 201 and a viewing window 202 for easy inspection of the interior of the frame 1. Second sealing plates 3 are provided at both the front and rear ends of the frame 1. Two mounting sheet metals 5 are arranged parallel to each other on the top of the frame 1, located on one side of each of the two mounting blocks 4. Three feeding rollers 7 are evenly rotatably arranged between the two mounting sheet metals 5. A [missing information - likely a design feature] is provided between the two mounting sheet metals 5. An adjusting plate 8 is located between two feeding rollers 7. The adjusting plate 8 has two first adjusting holes 801, which are elongated holes. A slider 10 is slidably disposed in the first adjusting hole 801. An adjusting post 9 is provided on the adjusting plate 8. A threaded knob 11 is threadedly connected to the adjusting post 9. The threaded part of the threaded knob 11 passes through the adjusting post 9 and screws into the threaded hole of the slider 10. The upper surface of the adjusting plate 8 has a scale. The distance is adjusted by moving the two adjusting posts 9. When the post is moved to the appropriate position, the threaded knob 11 is rotated to lock the adjusting post 9 onto the adjusting plate 8, thereby limiting the width of the rubber strip.

[0028] like Figure 4 As shown, a supporting sheet metal 6 is provided on the mounting sheet metal 5, and a feeding plate 12 is provided on the supporting sheet metal 6. One end of the feeding plate 12 extends into the middle of the two mounting blocks 4. The feeding plate 12 has four second adjustment holes 121, which are elongated holes. Two adjustment blocks 13 are provided on the feeding plate 12, and two locking holes 131 are provided on the adjustment blocks 13. The two locking holes 131 are respectively opened opposite the two second adjustment holes 121. The adjustment blocks 13 are locked and fixed by screwing bolts through the locking holes 131 and the second adjustment holes 121 into the threaded holes evenly opened on the supporting sheet metal 6. The corners of the two adjustment blocks 13 facing each other are rounded to facilitate the passage of the rubber strip. The two adjustment blocks 13 further limit the width of the rubber strip and guide the rubber strip to prevent it from deviating when it is conveyed forward, which would affect the subsequent cutting accuracy.

[0029] like Figure 2As shown, the mounting block 4 has a sliding groove 401 and a mounting hole 402 on its side wall. The sliding groove 401 is located directly above the mounting hole 402. A sliding block 17 is slidably disposed in the sliding groove 401. A connecting groove 171 is formed at the middle of the top of the sliding block 17. A snap-fit ​​connector 18 is engaged in the connecting groove 171. A stud 20 is provided on the top of the snap-fit ​​connector 18, and the top of the snap-fit ​​connector 18 is located at the bottom of the stud 20. A threaded connecting hole 403 is formed on the top of the sliding groove 401. The top of the stud 20 is screwed into the threaded connecting hole 403 and extends above the mounting block 4. A rotating wheel 19 is sleeved on the top of the stud 20. A handle 21 is provided on the rotating wheel 19. By rotating the rotating wheel 19 with the handle 21, the stud 20 is rotated in the threaded connecting hole 403, thereby pushing the sliding block 17 to slide up and down along the sliding groove 401. A rotating shaft 16 is rotatably connected between the two sliding blocks 17 via a bearing. A cutting mechanism 15 is sleeved on the rotating shaft 16. The cutting mechanism 15 includes multiple cutters 151 and multiple limiting blocks 152. The cutters 151 are annular cutters. The multiple limiting blocks 152 are fixedly arranged on the outer circumference of the rotating shaft 16. The multiple cutters 151 and the multiple limiting blocks 152 are staggered. The limiting blocks 152 further fix the cutters 151 and enhance the connection stability. The multiple limiting blocks 152 distribute the multiple cutters 151 at equal distances, thereby ensuring that the rubber strip is cut evenly and ensuring cutting accuracy. A bearing 23 is provided in the mounting hole 402. A feeding roller 14 is provided in the inner ring of the bearing 23. The upper surface of the feeding roller 14 is flush with the feeding plate 12, which facilitates the transportation of the rubber strip onto the feeding roller 14.

[0030] like Figure 3 and Figure 4 As shown, a power mechanism 25 is installed inside the frame 1. A chain 24 is installed at the output end of the power mechanism 25. The power mechanism 25 is connected to the feeding roller 7 and the feeding rubber roller 14 through the chain 24, thereby driving the feeding roller 7 and the feeding rubber roller 14 to rotate. A motor is installed on the side wall of the mounting block 4. The output end of the motor is connected to the end of the rotating shaft 16. The motor drives the rotating shaft 16 and the slitting mechanism 15 to rotate. A protective shell 28 is installed on the side wall of the mounting block 4. The protective shell 28 covers the motor and protects it. A baffle plate 27 is installed on the top of the two mounting blocks 4. The baffle plate 27 is located above the slitting mechanism 15. A blanking sheet metal 26 is installed between the two mounting blocks 4. The blanking sheet metal 26 is arranged at an angle. The top of the blanking sheet metal 26 is located below the intersection of the feeding rubber roller 14 and the cutter 151, which facilitates the guidance of the slitting rubber strip to the appropriate position.

[0031] The frame 1 is equipped with casters 22 at each of the four corners of its bottom, which allows the entire device to be moved easily and is convenient to use.

[0032] Specifically, the implementation method involves using a power mechanism 25 to drive a chain 24 to rotate the feeding roller 7 and the feeding rubber roller 14. This causes the adjusting pin 9 to move on the adjusting plate 8, adjusting the distance between the two adjusting pins 9 according to the scale on the adjusting plate 8. When the pin 9 reaches the set distance, the threaded knob 11 is rotated to lock it in place, thus limiting the width of the rubber strip. Simultaneously, the distance between the two adjusting blocks 13 is adjusted to match the distance between the two adjusting pins 9, guiding the rubber strip and preventing it from shifting during forward transport, which would affect the accuracy of subsequent slitting. The rubber strip is then passed sequentially between the two adjusting pins 9 and the two adjusting blocks 13, and then through the feeding rubber roller 14 and the feeding roller. 7. The rubber strip is smoothly conveyed forward. At the same time, the motor is started to drive the slitting mechanism 15 to rotate. Multiple equally spaced cutters 151 slit the rubber strip. The slitting accuracy is precise and reliable, and the slitting efficiency is high. After a long period of use, the cutter 151 will wear down. At this time, the distance between the cutter 151 and the feeding roller 14 will increase, which will make it impossible to cut the rubber strip completely. Turning the handle 21 will drive the rotating wheel 19 and the stud 20 to rotate, which will push the sliding block 17 to slide down along the slide groove 401, so that the cutter 151 is close to the outer circumference of the feeding roller 14, thus ensuring that the cutter 151 cuts the rubber strip completely. There is no need to replace the cutter 151 directly. The adjustment is convenient and quick, effectively extending the service life of the cutter 151 and reducing costs.

[0033] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
