AI Technical Summary
但现有在将橡胶板裁切成定长尺寸的作业过程中，橡胶板在上料时易出现偏移错位的现象，往往需要人工手动纠偏对准后才能裁切，否则易造成裁切面的不平整，降低产品质量，需要解决
[0010]本实用新型的有益效果是：裁切橡胶板前，可先根据待裁切橡胶板的宽度和所需裁切的定长橡胶板的长度对导向限位机构和限位板进行调节，调节导向限位机构时，只需通过齿轮齿条机构带动对应的两导向板相对靠近或相背远离，直至两导向板之间的水平距离与橡胶板的宽度一致即可。调节限位板时，只需运行第三液压缸，使其活塞杆进行伸缩，即可带动限位板沿导柱左右移动，直至限位板左侧面与裁切刀之间的水平距离与所需裁切的定长橡胶板的长度一致即可。调整好后，即可进行裁切作业，具体为：由人工将待裁切的橡胶板从操作台左侧上料到操作台上并朝右推动橡胶板，使橡胶板的右端由左至右依次穿过左侧的两导向板、裁切刀和右侧的两导向板对应的区域后抵接到限位板左侧上，即上料完成，且此时由于两组导向限位机构的两导向板的导向限位作用，能有效保证橡胶板的位置准确对中，不存在偏移错位的问题，无需人工再次纠偏调整。然后，运行各导向板上的第二液压缸，使其活塞杆伸长，带动压板下移直至压板抵压到橡胶板上，从而能够从裁切部位的左右两侧将橡胶板有效压紧固定住，避免裁切过程中的工件位移，相互配合下，更能保证裁切面的平整，提高整体裁切质量。接着，将利用电动滑块将裁切刀移动至橡胶板的前方或后方，再通过第一液压缸的活塞杆的伸长带动裁切刀下移，直至裁切刀伸入刀槽，然后再次通过电动滑块带动裁切刀朝前或朝后进给，即可实现裁切操作。之后，第二液压缸的活塞杆带动压板上移复位，解除对橡胶板的压紧限位，再将切割下来的橡胶板取下，然后按前述继续上料裁切即可。若后续裁切时，待裁切的橡胶板的宽度或所需定长橡胶板的长度发生变化时，只需按前述进行调节即可，操作便捷，更加实用。此外，由于将裁切机构、导向限位机构和定长量取机构均集中设置在了支座上，而支座与操作台之间又是可拆设置的，使得在实际应用中，可根据实际需求对整个裁切装置进行灵活拆装更换，更方便对裁切装置进行检修维护，更加便捷实用。

Description
Technical Field
[0001] This utility model belongs to the field of cutting technology, specifically relating to a cutting device for rubber sheet production. Background Technology
[0002] Rubber sheets are sheet-like products with a certain thickness and large area, made primarily of rubber through vulcanization. They are typically produced by calendering or extruding compounded rubber, followed by vulcanization using a flat vulcanizing machine or a drum vulcanizing machine. After vulcanization, they can be cut into specific sizes or shapes as needed. However, in the current process of cutting rubber sheets to fixed lengths, misalignment is prone to occur during loading. Manual correction and alignment are often required before cutting, otherwise, uneven cut surfaces are likely, reducing product quality. This issue needs to be addressed. Utility Model Content
[0003] In view of this, the purpose of this utility model is to provide a rubber sheet production and cutting device that can realize automatic guiding, limiting and pressing and fixing of rubber sheets during material feeding, so as to solve the above problems.
[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a rubber sheet production cutting device, including an operating table, on which an inverted L-shaped support is detachably mounted. The horizontal portion of the support faces forward, and a guide rail is fixedly mounted on its bottom middle section along the front-back direction. An electric slider is slidably mounted on the guide rail. A first hydraulic cylinder is vertically fixedly mounted on the bottom of the electric slider. The piston rod of the first hydraulic cylinder faces downward and is fixedly connected to a cutting blade. A blade groove is formed on the top surface of the operating table corresponding to the cutting blade along the front-back direction. Guide and limiting mechanisms are provided on both the left and right sides of the guide rail. The limiting mechanism includes two guide plates spaced apart along the front-rear direction. The two guide plates move relative to each other or away from each other via a gear and rack mechanism. A second hydraulic cylinder is vertically fixed to the upper part of the opposite side of each of the two guide plates. The piston rod of the second hydraulic cylinder faces downward and is fixedly connected to a pressure plate. A vertical plate is fixed to the upper right side of the horizontal part of the support. A guide post with scale is fixed to the upper right side of the vertical plate along the left-right direction. A third hydraulic cylinder is fixed to the vertical plate below the guide post. The piston rod of the third hydraulic cylinder faces right and is fixedly connected to a limiting plate. The upper part of the limiting plate is slidably sleeved with the guide post.
[0005] Preferably, the gear and rack mechanism includes a motor fixedly mounted on the top of the horizontal part of the support. The output shaft of the motor passes through the horizontal part of the support downward and is fixedly sleeved with a gear. Both sides of the gear are meshed with racks. The top of the rack is slidably connected to the horizontal part of the support. The opposite ends of the two racks are fixedly connected to inverted L-shaped support rods downward. Two guide plates are fixedly connected to the bottom ends of the two support rods respectively.
[0006] Preferably, a T-shaped slider is fixedly connected to the top of the rack, and a corresponding T-shaped groove is provided on the bottom of the horizontal part of the support corresponding to the slider, and the slider is slidably disposed in the corresponding groove.
[0007] Preferably, a mounting plate is fixedly provided at the rear bottom of the vertical part of the support. A plurality of positioning plates are fixedly provided at the bottom of the mounting plate, spaced apart along the front-rear direction. A plurality of through holes are provided on the positioning plates. A positioning groove is provided on the operating table corresponding to the positioning plate. An electric push rod is fixedly mounted on the bottom of the operating table corresponding to the positioning groove. The telescopic end of the electric push rod faces rearward and is fixedly connected to a moving plate. A plurality of insert rods arranged in a rectangular array are fixedly provided at the position corresponding to the positioning groove on the front side of the moving plate. An insertion hole is provided on the operating table corresponding to the insert rod. The insertion hole extends forward to the front side of the foremost positioning groove. The mounting plate abuts against the operating table. The positioning plate is inserted into the corresponding positioning groove. The through holes and insertion holes correspond one-to-one. The moving plate abuts against the rear side of the operating table. The insert rod is inserted into the corresponding insertion hole and passes through the corresponding through hole.
[0008] Preferably, the positioning plate is adapted to the corresponding positioning groove.
[0009] Preferably, the insertion rod is adapted to the corresponding insertion hole and through hole.
[0010] The beneficial effects of this utility model are as follows: Before cutting the rubber sheet, the guide limiting mechanism and the limiting plate can be adjusted according to the width of the rubber sheet to be cut and the length of the fixed-length rubber sheet to be cut. When adjusting the guide limiting mechanism, it is only necessary to drive the corresponding two guide plates to move closer or further apart through the gear and rack mechanism until the horizontal distance between the two guide plates is consistent with the width of the rubber sheet. When adjusting the limiting plate, it is only necessary to operate the third hydraulic cylinder to extend and retract its piston rod, which will drive the limiting plate to move left and right along the guide post until the horizontal distance between the left side of the limiting plate and the cutting blade is consistent with the length of the fixed-length rubber sheet to be cut. After adjustment, the cutting operation can begin. Specifically, the rubber sheet to be cut is manually loaded onto the operating table from the left side and pushed to the right. The right end of the rubber sheet passes sequentially from left to right through the corresponding areas of the two guide plates on the left, the cutting blade, and the two guide plates on the right, finally abutting against the left side of the limiting plate. This completes the loading process. At this point, due to the guiding and limiting effect of the two guide plates of the two sets of guiding and limiting mechanisms, the rubber sheet's position is effectively ensured to be accurately centered, eliminating any offset or misalignment issues and requiring no further manual adjustment. Then, the second hydraulic cylinder on each guide plate is activated, extending its piston rod and causing the pressure plate to move downwards until it presses against the rubber sheet. This effectively presses and fixes the rubber sheet from both sides of the cutting area, preventing workpiece displacement during the cutting process. This coordinated action ensures a flat cutting surface and improves the overall cutting quality. Next, the electric slider moves the cutting blade to the front or rear of the rubber sheet. Then, the extension of the piston rod of the first hydraulic cylinder moves the cutting blade downwards until it enters the blade groove. The electric slider then moves the cutting blade forward or backward again to complete the cutting operation. Afterwards, the piston rod of the second hydraulic cylinder moves the pressure plate upwards to reset, releasing the pressure limit on the rubber sheet. The cut rubber sheet is then removed, and the cutting process can continue as described above. If the width of the rubber sheet to be cut or the required length of the rubber sheet changes during subsequent cutting, adjustments can be made as described above, making operation convenient and practical. Furthermore, since the cutting mechanism, guide and limit mechanism, and length measuring mechanism are all centrally located on the support, and the support is detachable from the operating table, the entire cutting device can be flexibly disassembled and replaced according to actual needs in practical applications. This facilitates maintenance and repair of the cutting device, making it more convenient and practical. Attached Figure Description

Detailed Implementation
[0013] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments: like Figures 1 to 7 As shown, a rubber sheet production and cutting device includes an operating table 1. An inverted L-shaped support 2 is detachably mounted on the operating table 1. The horizontal portion of the support 2 faces forward, and a guide rail 3 is fixedly mounted on its bottom middle section along the front-back direction. An electric slider 4 slides on the guide rail 3. A first hydraulic cylinder 5 is vertically fixed at the bottom of the electric slider 4. The piston rod of the first hydraulic cylinder 5 faces downward and is fixedly connected to a cutting blade 6. A blade groove 7 is formed on the top surface of the operating table 1 corresponding to the cutting blade 6 along the front-back direction. Guide limiting mechanisms are provided on both the left and right sides of the guide rail 3. The guide limiting mechanisms include two guide plates 8 spaced apart along the front-back direction. The two guide plates 8 move relative to or away from each other via a gear and rack mechanism. A second hydraulic cylinder 9 is vertically fixed to the upper part of the opposite side of each of the two guide plates 8. The piston rod of the second hydraulic cylinder 9 faces downward and is fixedly connected to a pressure plate 10. A vertical plate 11 is fixedly installed on the upper right side of the horizontal part of the support 2. A guide post 13 with a scale 12 is fixedly installed on the upper right side of the vertical plate 11 along the left and right direction. A third hydraulic cylinder 14 is fixedly installed on the vertical plate 11 below the guide post 13. The piston rod of the third hydraulic cylinder 14 faces to the right and is fixedly connected to a limit plate 15. The upper part of the limit plate 15 is slidably sleeved with the guide post 13. Before cutting the rubber sheet, the guide limiting mechanism and the limiting plate 15 can be adjusted according to the width of the rubber sheet to be cut and the length of the fixed-length rubber sheet to be cut. When adjusting the guide limiting mechanism, simply use the gear and rack mechanism to drive the corresponding two guide plates 8 to move closer or further apart until the horizontal distance between the two guide plates 8 is consistent with the width of the rubber sheet. When adjusting the limiting plate 15, simply operate the third hydraulic cylinder 14 to extend and retract its piston rod, which will drive the limiting plate 15 to move left and right along the guide post 13 until the horizontal distance between the left side of the limiting plate 15 and the cutting blade is consistent with the length of the fixed-length rubber sheet to be cut. After adjustment, the cutting operation can begin. Specifically, the rubber sheet to be cut is manually loaded onto the operating table 1 from the left side and pushed to the right. The right end of the rubber sheet passes through the corresponding areas of the two guide plates 8 on the left, the cutting blade 6, and the two guide plates 8 on the right, and then abuts against the left side of the limiting plate 15. This completes the loading. At this point, due to the guiding and limiting effect of the two guide plates of the two sets of guiding and limiting mechanisms, the rubber sheet is effectively aligned accurately, without any offset or misalignment, eliminating the need for manual adjustment. Then, the second hydraulic cylinder 9 on each guide plate 8 is activated, extending its piston rod and causing the pressure plate 10 to move downwards until it presses against the rubber sheet. This effectively presses and fixes the rubber sheet from both sides of the cutting area, preventing workpiece displacement during the cutting process. The combined action ensures a flat cutting surface and improves the overall cutting quality. Next, the electric slider 4 moves the cutting blade 6 to the front or rear of the rubber sheet. Then, the extension of the piston rod of the first hydraulic cylinder 5 drives the cutting blade 6 downward until it enters the blade groove 7. The electric slider 4 then drives the cutting blade 6 forward or backward to complete the cutting operation. Afterward, the piston rod of the second hydraulic cylinder 9 drives the pressure plate 10 upward to reset, releasing the pressure limit on the rubber sheet. The cut rubber sheet is then removed, and the cutting process can continue as described above. If the width of the rubber sheet to be cut or the required length of the rubber sheet changes during subsequent cutting, adjustments can be made as described above, making the operation convenient and practical. Furthermore, since the cutting mechanism, guide and limit mechanism, and length measuring mechanism are all concentrated on the support 2, and the support 2 and the operating table 1 are detachable, the entire cutting device can be flexibly disassembled and replaced according to actual needs in practical applications. This makes maintenance and repair of the cutting device more convenient and practical.
[0014] In this embodiment, the gear and rack mechanism includes a motor 16 fixedly mounted on the top of the horizontal part of the support 2. The output shaft of the motor 16 passes downward through the horizontal part of the support 2 and is fixedly sleeved with a gear 17. The left and right sides of the gear 17 are meshed with racks 18. The top of the racks 18 is slidably connected to the horizontal part of the support 2. The opposite ends of the two racks 18 are fixedly connected to inverted L-shaped support rods 19. Two guide plates 8 are respectively fixedly connected to the bottom ends of the two support rods 19. When it is necessary to adjust the horizontal distance between the two guide plates 8, the corresponding motor 16 can be operated to drive the gear 17 to rotate. Through the meshing connection between the gear 17 and the rack 18 and the sliding connection between the rack 18 and the support 2, the two racks 18 can be moved closer or further apart, thereby driving the two guide plates 8 to move closer or further apart, thereby realizing the adjustment of the distance between the two guide plates 8. This is used to guide and limit rubber plates of different widths, with a wide range of applications and more flexible and convenient use.
[0015] In this embodiment, a T-shaped slider 20 is fixedly connected to the top of the rack 18. A corresponding T-shaped groove 21 is provided on the bottom of the horizontal part of the support 2 corresponding to the slider 20. The slider 20 is slidably disposed in the corresponding groove 21 to effectively guide and limit the movement of the rack 18.
[0016] In this embodiment, a mounting plate 22 is fixedly provided at the rear bottom of the vertical part of the support 2. Several positioning plates 23 are fixedly provided at the bottom of the mounting plate 22, which are spaced apart in the front-back direction. Several through holes 24 are provided on the positioning plates 23. A positioning groove 25 is provided on the operating table 1 corresponding to the positioning plate 23. An electric push rod 26 is fixedly mounted at the bottom of the operating table 1 corresponding to the positioning groove 25. The telescopic end of the electric push rod 26 faces backward and is fixedly connected to a moving plate 27. Several insertion rods 28 arranged in a rectangular array are fixedly provided at the position corresponding to the positioning groove 25 on the front side of the moving plate 27. An insertion hole 29 is provided on the operating table 1 corresponding to the insertion rod 28. The insertion hole 29 extends forward to the front side of the foremost positioning groove 25. The mounting plate 22 abuts against the operating table 1, the positioning plate 23 is inserted into the corresponding positioning groove 25, the through hole 24 corresponds one-to-one with the insertion hole 29, the moving plate 27 abuts against the rear side of the operating table 1, and the insertion rod 28 is inserted into the corresponding insertion hole 29 and passes through the corresponding through hole 24. This allows the entire support 2 to be removed by first operating the electric push rod 26 to extend its telescopic end until the insertion rod 28 exits the corresponding insertion hole 29, thus releasing the locking of the positioning plate 23, and then pulling out the positioning plate 23. When installing the support 2, simply insert the positioning plate 23 into the corresponding positioning groove 25, then operate the electric push rod 26 to retract its telescopic end, moving the moving plate 27 forward until the insertion rod 28 is inserted into the corresponding insertion hole 29 and passes through the corresponding through hole 24, thus fixing the positioning plate 23 in place. This completes the fixed installation of the support 2, ensuring a stable installation, simple operation, and greater practicality.
[0017] In this embodiment, the positioning plate 23 is adapted to the corresponding positioning groove 25 to ensure that the positioning plate 23 is smoothly inserted and installed in place.
[0018] In this embodiment, the insertion rod 28 is adapted to the corresponding insertion hole 29 and through hole 24 to ensure that the insertion rod 28 is smoothly inserted into place.
[0019] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
