Description

Technical Field

[0001] This invention relates to the field of cutting technology, and in particular to a rubber sheet cutting machine. Background Technology

[0002] Rubber sheets are thin, sheet-like products made from rubber raw materials through processing. They possess good elasticity and physical properties and can be manufactured in different thicknesses, hardnesses, and sizes to meet various applications and performance requirements. During the production process, rubber sheets need to be cut from larger sheets to ensure they conform to the shape and size required for use.

[0003] Related technology can be found in patent application CN221391249U, which discloses a cutting device for shaping and cutting rubber sheets. The device includes a U-shaped support frame; a drive motor is mounted on the top of the support frame; a fixed plate is mounted on the output end of the drive motor; the fixed plate is L-shaped; the interior of the fixed plate is hollow; and a telescopic rod is installed inside the fixed plate. In use, the rubber sheet to be cut is first placed on a suction cup, which effectively fixes the rubber sheet. After fixing, an electric push cylinder installed between the suction cup and the worktable brings the rubber sheet into contact with the cutter. A sliding rod at the bottom of the suction cup ensures stable movement and prevents deviation.

[0004] Regarding the aforementioned technologies, rubber sheets retain a certain degree of stickiness after cutting, causing them to adhere together and become difficult to separate, thus affecting the subsequent processing quality and production efficiency. Therefore, a rubber sheet cutting machine is urgently needed to solve these technical problems. Summary of the Invention

[0005] In order to improve the processing quality and production efficiency of rubber sheets, the present invention provides a rubber sheet cutting machine.

[0006] This invention provides a rubber sheet cutting machine, which adopts the following technical solution: A rubber sheet cutting machine includes a conveyor table for conveying rubber sheets and a cutting table for cutting rubber sheets. The cutting table is disposed on one side of the conveyor table and is connected to the conveyor table. The conveyor table is provided with a conveying assembly for conveying rubber sheets, and the cutting table is provided with a cutting assembly for cutting rubber sheets. A lifting cylinder is provided inside the cutting table, and a lifting hole is opened on the upper end face of the cutting table. A lifting platform is provided inside the cutting table and is located in the lifting hole of the cutting table. The lifting cylinder is vertically disposed inside the cutting table, and the piston rod of the lifting cylinder is fixedly connected to the lifting platform.

[0007] By adopting the above technical solution, when rubber sheets need to be cut, the worker places the larger sheet of rubber on the conveyor table and the cutting table, then starts the cutting component to cut the rubber sheet. The worker then starts the lifting cylinder, which lifts the lifting table to separate the two pieces of rubber sheet. The lifting cylinder is then started again to reset the lifting table, and then the conveyor component is started to push the rubber sheet, allowing the cut rubber sheet to proceed to the next process. The unprocessed rubber sheet is also pushed back to the cutting component. Through this single lifting process, the two bonded rubber sheets are separated, preventing them from sticking together after cutting and affecting subsequent processing quality and production efficiency, thus improving work efficiency.

[0008] Optionally, the conveying assembly includes a conveying plate, which is disposed at the end of the conveying table away from the cutting table. The conveying plate extends along the width of the conveying table. A conveying cylinder is provided on the side of the conveying plate away from the cutting table. The piston rod of the conveying cylinder is fixedly connected to the conveying plate. The conveying plate is slidably connected to the conveying table. A positioning groove is provided on the side of the conveying plate away from the conveying cylinder. A positioning bidirectional screw is provided in the positioning groove. A positioning motor is provided at one end of the conveying plate. The output shaft of the positioning motor passes through the conveying plate and is coaxially fixedly connected to the positioning bidirectional screw. Positioning plates are threaded to both ends of the positioning bidirectional screw, and the two positioning plates are arranged opposite to each other.

[0009] By adopting the above technical solution, when rubber sheets need to be transported by the conveying assembly, the worker places the rubber sheet on the conveying table, then starts the positioning motor, which drives the positioning bidirectional screw to rotate, thereby causing the two positioning plates to move towards each other, thus clamping the rubber sheet. Then the conveying cylinder is started, which pushes the rubber sheet, realizing automated processing and improving the stability of the rubber sheet on the device, which is conducive to improving work efficiency.

[0010] Optionally, the cutting assembly includes a support frame positioned directly above the cutting table. A cutting cylinder is mounted on the upper surface of the support frame. A cutting blade is fixedly connected to the piston rod of the cutting cylinder through the support frame. The cutting blade extends along the width of the cutting table and is positioned at one end of the support frame near the conveyor table. The support frame also includes a trimming cylinder. A connecting plate is fixedly connected to the piston rod of the trimming cylinder through the support frame. A connecting groove is formed on the lower surface of the connecting plate. A first bidirectional screw is located within the connecting groove. Two support rods are threaded to both ends of the first bidirectional screw. Each support rod has a cutter at its end away from the first bidirectional screw. The cutters extend along the length of the cutting table and are positioned opposite each other. An adjusting motor is located on one side of the connecting plate. The output shaft of the adjusting motor passes through the connecting plate and is coaxially fixedly connected to the first bidirectional screw.

[0011] By adopting the above technical solution, when it is necessary to cut a rubber sheet, the worker first starts the cutting cylinder according to the length. The cutting cylinder drives the cutting blade to cut the rubber sheet in the width direction. Then, according to the width, the adjusting motor is started. The adjusting motor drives the two cutting blades to move towards each other, thereby adjusting the part to be cut off. Then, the edge-cutting cylinder is started. The edge-cutting cylinder drives the connecting plate down, which in turn drives the two cutting blades down, so as to cut off both sides of the rubber sheet. This method is easy to understand and implement, and helps to improve work efficiency.

[0012] Optionally, the cutting table is a hollow cavity, and a recycling box is provided inside the cutting table. The recycling box is fixedly connected inside the cutting table, and the size of the recycling box is larger than the size of the lifting table. The lifting table has discharge ports on both sides, which extend along the length of the lifting table.

[0013] By adopting the above technical solution, and by setting up a recycling box and a discharge port, after the rubber sheet is cut off on both sides, the remaining scraps will enter the recycling box through the discharge port, which improves the cleanliness of the cutting table surface, avoids the residual scraps from affecting the subsequent cutting process, and helps to improve the stability of the device.

[0014] Optionally, each of the lifting platforms has a discharge plate at its outlet. A support ring is fixedly connected to the bottom of the lifting platform. The support ring has a drive screw and a sliding rod. One end of the discharge plate is threaded to the drive screw, and the other end is slidably connected to the sliding rod. The recycling box has a drive rod, which is vertically mounted on the lower surface of the recycling box. The drive rod has a first rack, and a first drive wheel meshes with the first rack. The first drive wheel is mounted on the support ring, and the first drive wheel is connected to the drive screw through a bevel gear pair.

[0015] By adopting the above technical solution, when the lifting platform rises, the first drive wheel and drive rod operate, thereby driving the drive screw to rotate, which in turn causes the discharge plate to move downward, thereby opening the discharge port and allowing the cut scraps to enter the recycling box through the discharge port. When the lifting platform resets, the discharge plate moves upward, thereby closing the discharge port and improving the cleanliness of the platform.

[0016] Optionally, the upper surface of the conveyor table is provided with a piston groove, and a support plate is provided at the piston groove. The upper surface of the support plate is flush with the upper surface of the conveyor table. A piston plate is provided at the piston groove of the conveyor table. The piston plate is horizontally arranged. A movable plate is fixedly connected to the side of the piston plate near the cutting table. Two movable rods are fixedly connected to the side of the lifting table near the movable plate. The two movable rods are arranged at both ends of the lifting table. A second drive wheel is provided between the movable rod and the movable plate. A connecting shaft is coaxially fixedly connected between the two second drive wheels. The connecting shaft is horizontally fixedly connected inside the cutting table. A second rack is provided on the opposite side of the movable rod and the movable plate. The second drive wheel meshes with the second rack. A number of through holes are opened on the upper surface of the support plate. The through holes are evenly arranged. When the lifting table rises, the movable plate and the piston plate descend synchronously.

[0017] By adopting the above technical solution, when the lifting platform rises, the moving rod rises synchronously, and under the action of the second drive wheel and the second rack, it drives the moving plate and the piston plate to fall. At this time, the rubber sheet on the conveying platform is attached to the support plate. Since the support plate has through holes and the piston plate falls, the volume of the piston groove of the conveying platform increases and the air pressure changes, so that when the rubber sheet is tightly attached to the support plate, it ensures that the rubber sheet on the conveying platform is always in a stable state when the rubber sheet is separated, which is beneficial to improving the stability of the device.

[0018] Optionally, the upper end face of the piston plate is provided with a plurality of rolling wheels, the top of which passes through the support plate and is flush with the upper surface of the support plate.

[0019] By adopting the above technical solution, the rolling wheel makes it easier to move when the rubber sheet needs to be pushed. When the moving plate descends, the rolling wheel will descend synchronously, thereby further improving the stability of the device.

[0020] Optionally, the bottom end of each discharge plate is fixedly connected to an inclined plate to facilitate the conveying of scrap materials.

[0021] By adopting the above technical solution and setting up an inclined plate, the scraps after cutting the rubber sheet flow into the recycling box through the inclined surface of the plate, which helps to improve recycling efficiency.

[0022] In summary, the present invention has at least one of the following beneficial technical effects: 1. By setting up a conveyor table, cutting table, conveying assembly, cutting assembly, lifting cylinder, lifting hole, and lifting platform, when rubber sheets need to be cut, the worker places the larger sheet of rubber on the conveyor table and the cutting table, then starts the cutting assembly to cut the rubber sheet. The worker then starts the lifting cylinder, which lifts the lifting platform to separate the two pieces of rubber sheet. The lifting cylinder is started again to reset the lifting platform, and then the conveying assembly is started to push the rubber sheet, so that the cut rubber sheet is pushed to the next process, and the unprocessed rubber sheet is pushed back to the cutting assembly. Through one lifting process, the two rubber sheets that are stuck together are separated, which avoids the rubber sheets sticking together after cutting and affecting the subsequent processing quality and production efficiency, thus improving work efficiency. 2. By setting up a recycling box and a discharge port, after the rubber sheet is cut off on both sides, the remaining scraps will enter the recycling box through the discharge port, which improves the cleanliness of the cutting table surface, avoids the residual scraps from affecting the subsequent cutting process, and helps to improve the stability of the device. 3. By setting up a support plate, piston plate, moving plate, moving rod, second drive wheel, connecting shaft, second rack, and through hole, when the lifting platform rises, the moving rod rises synchronously, and under the action of the second drive wheel and the second rack, it drives the moving plate and piston plate to descend. At this time, the rubber sheet on the conveyor platform adheres to the support plate. Since the support plate has a through hole and the piston plate descends, the volume of the piston groove of the conveyor platform increases, and the air pressure changes, so that when the rubber sheet adheres tightly to the support plate, it ensures that the rubber sheet on the conveyor platform is always in a stable state when the rubber sheet is separated, which helps to improve the stability of the device.

[0027] The present invention will be further described in detail below with reference to all the accompanying drawings.

[0028] This invention discloses a rubber sheet cutting machine.

[0029] Reference Figures 1-3 A rubber sheet cutting machine includes a conveyor table 1, a cutting table 2, a conveying assembly 3, a cutting assembly 4, and a recycling assembly 5. The cutting table 2 is located on one side of the conveyor table 1 and is connected to the conveyor table 1. The conveying assembly 3 is located on the conveyor table 1, the cutting assembly 4 is located on the cutting table 2, and the recycling assembly 5 is located inside the cutting table 2. The conveyor table 1 supports the conveying assembly 3, the cutting table 2 supports the cutting assembly 4, the conveying assembly 3 transports the rubber sheet, the cutting assembly 4 cuts the rubber sheet, and the recycling assembly 5 collects the scraps generated during the cutting process.

[0030] Reference Figures 1-3The cutting table 2 is equipped with a lifting cylinder 21, and a lifting hole 22 is opened on the upper end face of the cutting table 2. The cutting table 2 is equipped with a lifting platform 23, which is located in the lifting hole 22 of the cutting table 2. The lifting cylinder 21 is vertically installed in the cutting table 2, and the piston rod of the lifting cylinder 21 is fixedly connected to the lifting platform 23. When rubber sheets need to be cut, the worker places the larger sheet of rubber on the conveyor table 1 and the cutting table 2, then starts the cutting assembly 4 to cut the rubber sheet. The worker then starts the lifting cylinder 21, which lifts the lifting table 23 to separate the two pieces of rubber sheet. The lifting cylinder 21 is started again to reset the lifting table 23, and then the conveyor assembly 3 is started to push the rubber sheet, so that the cut rubber sheet is pushed to the next process, and the unprocessed rubber sheet is pushed back to the cutting assembly 4. Through this one lifting process, the two rubber sheets that are stuck together are separated, which prevents the rubber sheets from sticking together after cutting and affecting the subsequent processing quality and production efficiency, thus improving work efficiency.

[0031] Reference Figures 1-3 The conveying assembly 3 includes a conveying plate 31, which is located at the end of the conveying table 1 away from the cutting table 2. The conveying plate 31 extends along the width of the conveying table 1. A conveying cylinder 32 is provided on the side of the conveying plate 31 away from the cutting table 2. The piston rod of the conveying cylinder 32 is fixedly connected to the conveying plate 31. The conveying plate 31 is slidably connected to the conveying table 1. A positioning groove is provided on the side of the conveying plate 31 away from the conveying cylinder 32. A positioning bidirectional screw 33 is provided in the positioning groove. A positioning motor 34 is provided at one end of the conveying plate 31. The output shaft of the positioning motor 34 passes through the conveying plate 31 and is coaxially fixedly connected to the positioning bidirectional screw 33. Positioning plates 35 are threaded to both ends of the positioning bidirectional screw 33, and the two positioning plates 35 are arranged opposite to each other.

[0032] Reference Figures 1-3 When the rubber sheet needs to be transported via the conveying component 3, the operator places the rubber sheet on the conveying table 1, then starts the positioning motor 34. The positioning motor 34 drives the positioning bidirectional screw 33 to rotate, thereby causing the two positioning plates 35 to move towards each other, thus clamping the rubber sheet. Then the conveying cylinder 32 is started, and the conveying cylinder 32 pushes the rubber sheet. This achieves automated processing and improves the stability of the rubber sheet on the device, which is conducive to improving work efficiency.

[0033] Reference Figures 1-3The cutting assembly 4 includes a support frame 41, which is positioned directly above the cutting table 2. A cutting cylinder 42 is mounted on the upper surface of the support frame 41. The piston rod of the cutting cylinder 42 passes through the support frame 41 and is fixedly connected to a cutting blade 43. The cutting blade 43 extends along the width of the cutting table 2 and is positioned at one end of the support frame 41 near the conveyor table 1. A trimming cylinder 44 is also mounted on the support frame 41, and its piston rod passes through the support frame 41 and is fixedly connected to a connecting plate. 45. A connecting groove is provided on the lower end face of the connecting plate 45. A first bidirectional screw 46 is provided in the connecting groove. Two support rods 47 are threaded to both ends of the first bidirectional screw 46. Each support rod 47 is provided with a cutter 48 at the end away from the first bidirectional screw 46. The cutter 48 extends along the length of the cutting table 2. The two cutters 48 are arranged opposite to each other. An adjusting motor 49 is provided on one side of the connecting plate 45. The output shaft of the adjusting motor 49 passes through the connecting plate 45 and is coaxially fixedly connected to the first bidirectional screw 46.

[0034] Reference Figures 1-3 When it is necessary to cut the rubber sheet, the worker first starts the cutting cylinder 42 according to the length. The cutting cylinder 42 drives the cutting blade 43 to cut the rubber sheet in the width direction. Then, according to the width, the adjusting motor 49 is started. The adjusting motor 49 drives the two cutting blades 48 to move towards each other, thereby adjusting the part to be cut off. Then, the edge cutting cylinder 44 is started. The edge cutting cylinder 44 drives the connecting plate 45 to move downward, which in turn drives the two cutting blades 48 to move downward, so as to cut off both sides of the rubber sheet. This method is easy to understand and implement, and helps to improve work efficiency.

[0035] Reference Figures 1-3 The recycling component 5 includes a recycling box 51. The cutting table 2 is a hollow cavity, and the recycling box 51 is disposed inside the cutting table 2. The recycling box 51 is fixedly connected inside the cutting table 2. The size of the recycling box 51 is larger than the size of the lifting table 23. The lifting table 23 has discharge ports 52 on both sides, which extend along the length of the lifting table 23. By setting up the recycling box 51 and the discharge ports 52, after the rubber sheet is cut off on both sides, the remaining scraps will enter the recycling box 51 through the discharge ports 52, improving the cleanliness of the cutting table 2 surface, preventing the remaining scraps from affecting the subsequent cutting process, and improving the stability of the device.

[0036] Reference Figures 1-3Each discharge port 52 of the lifting platform 23 is equipped with a discharge plate 231. A support ring 232 is fixedly connected to the bottom end of the lifting platform 23. The support ring 232 is equipped with a drive screw 233 and a sliding rod. One end of the discharge plate 231 is threadedly connected to the drive screw 233, and the other end is slidably connected to the sliding rod. A drive rod 235 is provided inside the recycling box 51. The drive rod 235 is vertically arranged on the lower surface of the recycling box 51. A first rack 236 is provided on the drive rod 235. A first drive wheel 237 is meshed on the first rack 236. The first drive wheel 237 is arranged on the support ring 232. The first drive wheel 237 and the drive screw 233 are connected through a bevel gear pair. The bottom end of each discharge plate 231 is fixedly connected with an inclined plate 234 to facilitate the conveying of scrap materials. By setting the inclined plate 234, the scrap materials after cutting the rubber sheet flow into the recycling box 51 through the inclined surface of the inclined plate 234, which helps to improve the recycling efficiency.

[0037] Reference Figures 1-3 When the lifting platform 23 rises, the first drive wheel 237 and the drive rod 235 operate, thereby driving the drive screw 233 to rotate, which in turn causes the discharge plate 231 to move downward, thereby opening the discharge port 52, allowing the cut scraps to enter the recycling box 51 through the discharge port 52. When the lifting platform 23 resets, the discharge plate 231 moves upward, thereby closing the discharge port 52 and improving the cleanliness of the platform.

[0038] Reference Figures 1-3 A piston groove 11 is provided on the upper end face of the conveyor table 1, and a support plate 12 is provided at the piston groove 11. The upper surface of the support plate 12 is flush with the upper surface of the conveyor table 1. A piston plate 13 is provided at the piston groove 11 of the conveyor table 1. The piston plate 13 is horizontally arranged. A movable plate 14 is fixedly connected to the side of the piston plate 13 near the cutting table 2. Two movable rods 15 are fixedly connected to the side of the lifting table 23 near the movable plate 14. The two movable rods 15 are arranged at both ends of the lifting table 23. A second drive wheel 16 is provided between the movable rod 15 and the movable plate 14. A connecting shaft 17 is coaxially fixedly connected between the two second drive wheels 16. The connecting shaft 17 is horizontally fixedly connected inside the cutting table 2. A second rack 18 is provided on the opposite side of the movable rod 15 and the movable plate 14. The second drive wheel 16 meshes with the second rack 18. A number of through holes are provided on the upper end face of the support plate 12. The through holes are evenly arranged. When the lifting table 23 rises, the movable plate 14 and the piston plate 13 descend synchronously.

[0039] Reference Figures 1-3When the lifting platform 23 rises, the moving rod 15 rises synchronously, and under the action of the second drive wheel 16 and the second rack 18, it drives the moving plate 14 and the piston plate 13 to fall. At this time, the rubber sheet on the conveying platform 1 is attached to the support plate 12. Since the support plate 12 has through holes and the piston plate 13 falls, the volume of the piston groove 11 of the conveying platform 1 increases and the air pressure changes, so that when the rubber sheet is tightly attached to the support plate 12, the rubber sheet on the conveying platform 1 is always in a stable state when the rubber sheet is separated, which is beneficial to improving the stability of the device.

[0040] Reference Figures 1-3 The piston plate 13 has several rolling wheels 19 on its upper surface. The top of the rolling wheels 19 passes through the support plate 12 and is flush with the upper surface of the support plate 12. When it is necessary to push the rubber sheet, the rolling wheels 19 make it easier to move. When the moving plate 14 descends, the rolling wheels 19 will descend synchronously, thereby further improving the stability of the device.

[0041] The implementation principle of a rubber sheet cutting machine according to an embodiment of the present invention is as follows: When rubber sheets need to be cut, the operator places a large sheet of rubber on the conveyor table 1 and the cutting table 2. First, the cutting cylinder 42 is activated according to the length. The cutting cylinder 42 drives the cutting blade 43 to cut the rubber sheet in the width direction. Then, the adjusting motor 49 is activated according to the width. The adjusting motor 49 drives the two cutting blades 48 to move towards each other, thereby adjusting the part to be cut off. Next, the edge-cutting cylinder 44 is activated. The edge-cutting cylinder 44 drives the connecting plate 45 downward, which in turn drives the two cutting blades 48 downward, thereby cutting off both sides of the rubber sheet. Finally, the operator activates the lifting cylinder 21. The lifting cylinder 21 lifts the lifting platform 23, separating the two rubber pieces. The lifting cylinder 21 is then activated again to reset the lifting platform 23. The positioning motor 34 is then activated, which drives the positioning bidirectional screw 33 to rotate, thereby causing the two positioning plates 35 to move towards each other and clamp the rubber pieces. Then the conveying cylinder 32 is activated to push the rubber pieces to the next process and pushes the untreated rubber pieces back to the cutting component 4. Through this lifting process, the two bonded rubber pieces are separated, preventing them from sticking together after cutting and affecting subsequent processing quality and production efficiency, thus improving work efficiency.

[0042] The above are all preferred embodiments of the present invention and are not intended to limit the scope of protection of the present invention. Therefore, all equivalent changes made in accordance with the structure, shape and principle of the present invention should be covered within the scope of protection of the present invention.
