Description

Technical Field

[0001] This invention belongs to the field of rubber roller manufacturing technology, and specifically relates to a cutting device and cutting method for rubber roller manufacturing. Background Technology

[0002] Rubber rollers are a type of industrial product made with a metal or other material core, covered with rubber, and vulcanized. Their structure typically includes an outer rubber layer, a hard rubber layer, a core, a roller neck, and ventilation holes. The manufacturing process involves multiple steps, including core sandblasting, bonding, rubber coating, fabric wrapping, vulcanization in a vulcanizing tank, and surface finishing. These products have a wide range of applications, primarily serving industries such as papermaking, dyeing and printing, food processing, metallurgy, and plastics processing.

[0003] Chinese patent CN218080684U discloses a cutting device for producing rubber rollers, including an operating table. A placement block with a placement groove is fixedly mounted on the upper surface of the operating table. A limiting frame with a sliding mechanism is fixedly mounted on the limiting frame. A cutting machine is fixedly mounted on the upper surface of the operating table. A fixing block and a fixing plate are fixedly mounted on one side of the operating table. A pipe is placed into the placement groove on the placement block. The motor is turned on, driving a gear to rotate. When the gear is positioned at the upper right of the circular shaft, the moving plate is located at the lower end of the rectangular frame. The connecting block will cause a semi-circular block to engage with the pipe. When the gear moves to the left, the semi-circular block will move the pipe towards the cutting machine. Because the semi-circular block presses down on the pipe, it facilitates the cutting machine's cutting of the pipe. The cutting distance is determined by the number of circular shafts, reducing manual operation and improving work efficiency.

[0004] When cutting pipes, burrs will appear on the cut surface. However, the above-mentioned technical solutions cannot remove the burrs on the pipes, which can easily cut workers when handling the pipes. Summary of the Invention

[0005] The purpose of this invention is to provide a cutting device and method for producing rubber rollers, which aims to solve the problem that burrs easily appear on the cut surface when cutting pipes using existing cutting devices for producing rubber rollers.

The second scraper structure is mounted on the translation assembly and can abut against the end of the pipe away from the first scraper structure when the translation assembly moves.

[0010] The rubbing component, set on the worktable, can rub the cut pipe to rotate as it is moved away from under the cutting component.

[0011] A further technical solution of the present invention is that the first scraper structure includes a first sliding cavity formed on the clamping assembly, a first sliding member is slidably disposed in the first sliding cavity, a first elastic member is disposed inside the first sliding cavity to push the first sliding member toward the positioning assembly, a first scraper is slidably disposed on the part of the first sliding member located outside the upright plate, and a V-shaped groove is provided on the side of the first scraper near the positioning assembly.

[0012] A further technical solution of the present invention is that the second scraper structure includes a swing block hinged to the translation component, a second sliding cavity is provided inside the swing block, a second sliding member is slidably disposed inside the second sliding cavity, a second elastic member is provided inside the second sliding cavity to push the second sliding member to move out of the second sliding cavity, a second scraper is slidably disposed on the second sliding member, a V-shaped groove is provided on one side of the second scraper, a torsion spring is provided at the pivot of the swing block to move the second scraper away from the pipe, and an L-shaped plate is provided on the table. When the translation component drives the second scraper structure to move, the L-shaped plate can push the swing block to stand up and make the second scraper contact the pipe.

[0013] A further technical solution of the present invention is that the rubbing assembly includes a column fixed above the worktable, a straight plate is provided on the column, a sliding column is slidably provided on the straight plate, a rubbing plate is provided at the bottom of the sliding column, a third elastic element is provided between the rubbing plate and the straight plate to push the rubbing plate against the pipe, and a nut is threadedly connected to the end of the sliding column away from the rubbing plate.

[0014] A further technical solution of the present invention is that the clamping assembly includes a vertical plate arranged on the translation plate, a connecting shaft passing through the vertical plate is provided on the vertical plate, and an air shaft is provided at one end of the vertical plate near the positioning assembly. The air shaft is located above the positioning assembly and close to the cutting assembly.

[0015] A further technical solution of the present invention is that an extension plate is provided on one side of the translation plate, a second slide rail is provided on the extension plate, the upright plate is slidably disposed on the second slide rail, a mounting plate is provided at the end of the extension plate away from the positioning component, a telescopic component for driving the upright plate to slide on the second slide rail is provided on the mounting plate, and the end of the connecting shaft away from the air shaft is disposed on the mounting plate.

[0016] A further technical solution of the present invention is that a first sliding groove is provided on the upright plate, a slider is slidably arranged inside the first sliding groove, a connecting shaft passes through the slider, a lead screw is rotatably connected above the slider, a horizontal plate is fixedly connected above the upright plate, the lead screw is threadedly connected inside the horizontal plate, a second sliding groove is provided on the mounting plate, one end of the connecting shaft slides inside the second sliding groove and is fixed by bolts.

[0017] A further technical solution of the present invention is that the workbench is provided with a support member for supporting the pipe.

[0018] A cutting method for producing rubber rollers includes the following steps:

[0019] S1. Place the pipe on the support and positioning assembly, and position the pipe using the positioning assembly;

[0020] S2. Open the air shaft to clamp and fix the pipe;

[0021] S3. The cutting assembly moves downward to cut the pipe;

[0022] S4. Start the translation component, so that the positioning component and the air shaft drive the cut pipe away from under the cutting component, while another air shaft and positioning component move down to the bottom of the cutting component. During the process of the air shaft and positioning component moving away from under the cutting component, the first scraper structure will always abut against one end of the pipe, and the second scraper structure abuts against the other end of the pipe under the action of the L-shaped plate.

[0023] S5. The air shaft releases its grip on the pipe, and the pipe comes into contact with the rubbing component during the movement, causing the pipe to rotate.

[0024] S6. The translation component continues to move, causing the second scraper structure to separate from the L-shaped plate when the pipe separates from the rubbing component. Under the action of the torsion spring, the second scraper structure rotates away from the pipe until another air shaft and positioning component move to the bottom of the cutting component and stop.

[0025] S7. Unload the cut pipe and feed it onto the air shaft located below the cutting assembly.

[0026] Compared with the prior art, the beneficial effects of the present invention are:

[0027] 1. Through the first and second scraper structures set on the clamping and translation components, the inner and outer circular edges of both ends of the pipe are automatically scraped during the pipe's movement after cutting, effectively removing the burrs generated during cutting. The second scraper structure automatically stands up and presses against the pipe end face during translation through the cooperation of the L-shaped plate and torsion spring. It automatically resets after disengagement, requiring no manual intervention and achieving a high degree of automation. In conjunction with the rubbing component, the pipe rotates during its movement, ensuring that the scraper can circumferentially and evenly remove burrs around the pipe end face, improving the processing effect.

[0028] 2. The clamping assembly uses an air shaft to tighten from inside the pipe, which not only provides reliable fixation, but also provides internal support for the cutting area due to its proximity to the cutting point, effectively preventing pipe deformation or uneven cuts caused by radial force during cutting. Precise positioning and length control: Through positioning components (such as Y-shaped frames and rollers) and adjustable clamping components, in conjunction with the upright plate as a stop, the pipe can be quickly positioned and the cutting length can be precisely controlled.

[0029] 3. The device is designed with dual stations (each side of the translation component has a set of clamping and positioning components), realizing a continuous cycle of "cutting-removal / deburring-loading". While one station is cutting, the other station can unload and load materials, greatly reducing equipment downtime. Cutting, deburring, and transfer are integrated into one device, eliminating the need for separate deburring after cutting in traditional processes, thus shortening the production cycle.

[0039] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0040] Please see Figures 1-7 The present invention provides the following technical solution: a cutting device for producing rubber rollers, comprising a worktable 1, a clamping assembly 2, a positioning assembly 3, a cutting assembly 4, a translation assembly 5, and a scraper assembly 6.

[0041] Both the clamping component 2 and the positioning component 3 are installed on the worktable 1. The pipe 7 is placed on the positioning component 3, so that the pipe 7 is positioned below the cutting component 4 under the action of the positioning component 3. The cutting component 4 is installed on the worktable 1 and is used to cut the pipe 7. After the positioning component 3 positions the pipe 7, the clamping component 2 clamps and fixes the pipe 7. After fixing, the cutting component 4 cuts the pipe 7. The cut pipe 7 is moved from the cutting component 4 to the scraper component 6 by the translation component 5 to remove the burrs on the cut pipe 7.

[0042] Please see Figure 1 The workbench 1 includes a tabletop 11, a support leg installed under the tabletop 11, a side plate 12 installed on one side of the tabletop 11, and a cutting assembly 4 installed on the side plate 12.

[0043] Please see Figures 1-2 The translation component 5 includes a translation plate 51 disposed on a table 11. A first slide rail 52 is also disposed on the table 11, extending in the transverse direction of the table 11. The translation plate 51 slides laterally on the table 11 via the first slide rail 52. A transverse groove 53 is provided on the table 11, with the length direction of the transverse groove 53 parallel to the length direction of the first slide rail 52. A first screw 54 is rotatably disposed inside the transverse groove 53. A protrusion is disposed on the translation plate 51 that can slide inside the transverse groove 53 and is threadedly connected to the first screw 54. A first driving member 55, which is a motor, is also disposed on the worktable 1 to drive the first screw 54 to rotate. When the motor runs, it can drive the first screw 54 to rotate. The rotation of the first screw 54 can drive the protrusion to slide inside the transverse groove 53 and simultaneously drive the translation plate 51 to slide on the table 11.

[0044] Please see Figures 2-3 The positioning component 3 includes a Y-shaped frame 31 fixed on the translation plate 51. Two rollers 32 are rotatably mounted on the two legs above the Y-shaped frame 31. The two rollers 32 have the same diameter and a gap between them. The pipe 7 can be placed on the two rollers 32, so that the two rollers 32 play a role in supporting the pipe 7, which can position the pipe 7 and prevent the position of the pipe 7 from shifting. At the same time, the positioning component 3 can be used to support pipes 7 with different radius sizes.

[0045] Please see Figures 2-3 The clamping assembly 2 includes a vertical plate 21 mounted on the translation plate 51. The vertical plate 21 is positioned perpendicular to the translation plate 51. A connecting shaft 22 is mounted on the vertical plate 21 and passes through the vertical plate 21. An air expansion shaft 23 is mounted at one end of the vertical plate 21 near the positioning assembly 3. The air expansion shaft 23 is located above the positioning assembly 3 and close to the cutting assembly 4. When feeding the pipe 7, one end of the pipe 7 is moved above the positioning assembly 3, and the air expansion shaft 23 is inserted into the interior of the pipe 7, pushing the pipe 7 until one end abuts against the vertical plate 21, thereby fixing the cutting length of the pipe 7. Then, the air expansion shaft 23 expands inside the pipe 7 to fix the pipe 7 and prevent displacement of the pipe 7 during cutting. In addition, since the air expansion shaft 23 is close to the cutting assembly 4, it can support the part of the pipe 7 being cut, preventing the radial force generated by the cutting assembly 4 from deforming one end of the pipe 7 during cutting.

[0046] Please see Figures 2-3 An extension plate 511 is provided on one side of the translation plate 51. A second slide rail 24 is provided on the extension plate 511. The second slide rail 24 is arranged in a direction perpendicular to the first slide rail 52. The upright plate 21 is slidably mounted on the second slide rail 24, so that the upright plate 21 can move closer to or away from the positioning component 3 via the second slide rail 24. A mounting plate 25 is provided at the end of the extension plate 511 away from the positioning component 3. A telescopic member 26 is provided on the mounting plate 25. The telescopic end of the telescopic member 26 passes through the mounting plate 25 and is connected to the upright plate 21. The telescopic member 26 is a hydraulic cylinder used to drive the upright plate 21 to slide on the second slide rail 24. The end of the connecting shaft 22 away from the air shaft 23 is fixed on the mounting plate 25. When the upright plate 21 slides on the second slide rail 24, the connecting shaft 22 can slide inside the upright plate 21, so that the air shaft 23 does not move with the upright plate 21. The air shaft 23 always remains in a position close to the cutting component 4.

[0047] A first groove 211 is provided on the upright plate 21, and a slider 212 is provided inside the first groove 211. The slider 212 can slide up and down inside the first groove 211. A connecting shaft 22 passes through the slider 212. A lead screw 213 is rotatably connected above the slider 212. A horizontal plate 214 is fixedly connected above the upright plate 21. The lead screw 213 is threaded into the horizontal plate 214. A second groove 251 is provided on the mounting plate 25. One end of the connecting shaft 22 slides inside the second groove 251 and is fixed by a bolt. By loosening the bolt and rotating the lead screw 213, the lead screw 213 drives the slider 212 to slide up and down inside the first groove 211. At the same time, the connecting shaft 22 also slides up and down inside the second groove 251. This allows the position of the air shaft 23 to be adjusted so that the air shaft 23 is coaxial with the axis of the pipe 7. This makes the device applicable to cutting pipes 7 of different radii, thus improving the applicability of the device.

[0048] The cutting assembly 4 includes a third slide rail 41 mounted on the side plate 12, which is perpendicular to the ground. A sliding frame 42 is slidably mounted on the third slide rail 41. A second screw 43, which is threadedly connected to the sliding frame 42, is rotatably mounted on the side plate 12. A second driving member 44 is also mounted on the side plate 12 to drive the second screw 43 to rotate. The second driving member 44 drives the second screw 43 to rotate, thereby driving the sliding frame 42 to slide up and down on the third slide rail 41. A saw blade 45 is mounted on the sliding frame 42, which is located above the pipe 7. When the sliding frame 42 moves downward, it drives the saw blade 45 to move downward, thus cutting the pipe 7.

[0049] Please see Figures 4-6The scraper assembly 6 includes a first scraper structure 61 and a second scraper structure 62. The first scraper structure 61 is mounted on the vertical plate 21, and the second scraper structure 62 is mounted on the translation plate 51. It can be used to remove burrs from both ends of the cut-off pipe 7.

[0050] The first scraper structure 61 includes a first sliding cavity 611 formed on the upright plate 21. A first sliding member 612 is slidably disposed inside the first sliding cavity 611. A first elastic member 613 is disposed inside the first sliding cavity 611 to push the first sliding member 612 toward the positioning component 3. An opening is provided on the side of the first sliding cavity 611 near the positioning component 3. The first sliding member 612 protrudes outside the upright plate 21 through the opening. A first scraper 614 is disposed on the part of the first sliding member 612 located outside the upright plate 21. The first scraper 614 can slide up and down on the first sliding member 612, thereby adjusting the height position of the first scraper 614. A V-shaped groove is provided on the side of the first scraper 614 near the positioning component 3, and one end of the opening of the V-shaped groove faces the positioning component 3, so that the edges of the inner circle and the outer circle of the tube 7 abut against the V-shaped groove of the first scraper 614.

[0051] The second scraper structure 62 includes a swing block 621 hinged to a translation plate 51. A second sliding cavity 622 is formed inside the swing block 621, with an opening on one side. When the swing block 621 is upright, the opening faces the positioning assembly 3. A second sliding member 623 is slidably disposed inside the second sliding cavity 622, and the second sliding member 623 can slide inside the swing block 621 towards the opening. A second elastic member 624 is disposed inside the second sliding cavity 622, and the second elastic member 624 can push the second sliding member 623 to slide towards the opening. A second scraper 625 is disposed on the second sliding member 623, and the second scraper 625 can slide on the second sliding member 623. When the swing block 621 is upright, the second scraper 625... The second scraper 625 is able to slide towards or away from the axis of the pipe 7. The second scraper 625 is provided with a V-groove on the side near the positioning component 3. The edges of the inner and outer circles of the pipe 7 can abut against the V-groove of the second scraper 625. An L-shaped plate 626 is provided on the table 11. The vertical and horizontal surfaces of the L-shaped plate 626 are both isosceles trapezoids, and the upper bottom edge of the vertical surface is connected to the lower bottom edge of the horizontal surface. When the translation plate 51 moves, the swing block 621 can contact the L-shaped plate 626, which can push the swing block 621 to stand up and be perpendicular to the translation plate 51. A torsion spring 627 is provided at the pivot of the swing block 621. When the swing block 621 is disengaged from the L-shaped plate 626, the torsion spring 627 can make the swing block 621 rotate to a horizontal state.

[0052] The cut pipe 7 will be located between the first scraper structure 61 and the second scraper structure 62. Under the action of the first elastic member 613 and the second elastic member 624, the first scraper 614 and the second scraper 625 will abut against the edges of both sides of the pipe 7. Then, the pipe 7 will be driven to rotate, so that the first scraper structure 61 and the second scraper structure 62 can clean the burrs at the edge of the pipe 7. The V-groove of the scraper can adapt to the scraper wear and the fluctuation of the pipe size, and always fit tightly against the inner and outer circular edges of the pipe, so as to achieve burr cleaning without dead angles and without the need to frequently adjust the scraper position.

[0053] Please see Figure 7 A rubbing assembly 8 is provided above the workbench 1. The rubbing assembly 8 can drive the cut pipe 7 to rotate when the positioning assembly 3 moves it. The rubbing assembly 8 includes a column 81 fixed above the workbench 1. A straight plate 82 is fixedly connected to the bottom of the column 81. Two sliding columns 83 pass through the straight plate 82. A rubbing plate 84 is fixedly connected to the bottom of the sliding column 83. A third elastic element 85 is provided between the rubbing plate 84 and the straight plate 82. Under the action of the third elastic element 85, the rubbing plate 84 can be pushed to abut against the pipe 7. A thread is provided at the end of the sliding column 83 away from the rubbing plate 84, and a nut is threaded on the thread. The height of the rubbing plate 84 can be adjusted by the nut to adapt to pipes 7 of different sizes.

[0054] In summary, the clamping assembly 2, positioning assembly 3, scraper assembly 6, and rubbing assembly 8 are each provided in two sets. The clamping assembly 2, positioning assembly 3, and scraper assembly 6 are all located on both sides of the translation plate 51, while the rubbing assembly 8 is located on both sides of the cutting assembly 4. After the pipe 7 is cut, the translation plate 51 uses one of the clamping assembly 2 and positioning assembly 3 to move the cut pipe 7 away from under the cutting assembly 4. The other clamping assembly 2 and positioning assembly 3 move to the bottom of the cutting assembly 4. During the process of the clamping assembly 2 and positioning assembly 3 moving away from under the cutting assembly 4, the first scraper structure 61 always abuts against one end of the pipe 7. The second scraper structure 62 abuts against the other end of the pipe 7 under the action of the L-shaped plate 626. Then, the air shaft 23 releases its grip on the pipe 7. During the movement, the pipe 7 comes into contact with the rubbing component 8, causing the rubbing component 8 to rub the pipe 7 and rotate. When the pipe 7 rotates, the scraper component 6 can remove the burrs on the pipe 7. The translation plate 51 continues to move, so that when the pipe 7 is separated from the rubbing component 8, the second scraper structure 62 is separated from the L-shaped plate 626. Under the action of the torsion spring 627, the second scraper structure 62 rotates away from the pipe 7, so that the worker can take the pipe 7 out of the air shaft 23.

[0055] A support member 9 is provided on the tabletop 11. The support member 9 has a V-shaped surface, on which the pipe 7 can be placed and supported.

[0056] A cutting method for producing rubber rollers includes the following steps:

[0057] S1. Place the pipe 7 on the support 9 and the positioning component 3, and position the pipe 7 using the positioning component 3;

[0058] S2. Open the air shaft 23 to clamp and fix the pipe 7;

[0059] S3, the cutting component 4 moves downward to cut the pipe 7;

[0060] S4. Start the translation component 5, so that the positioning component 3 and the air shaft 23 drive the cut pipe 7 to move away from under the cutting component 4, while another air shaft 23 and the positioning component 3 move downwards from the cutting component 4. During the process of the air shaft 23 and the positioning component 3 moving away from under the cutting component 4, the first scraper structure 61 will always abut against one end of the pipe 7, and the second scraper structure 62 abuts against the other end of the pipe 7 under the action of the L-shaped plate 626.

[0061] S5. The air shaft 23 releases its clamping on the pipe 7, and the pipe 7 comes into contact with the rubbing component 8 during the movement, causing the pipe 7 to rotate.

[0062] S6. The translation component 5 continues to move, so that when the pipe 7 separates from the rubbing component 8, the second scraper structure 62 separates from the L-shaped plate 626. Under the action of the torsion spring 627, the second scraper structure 62 rotates away from the pipe 7 until another air shaft 23 and the positioning component 3 move to the bottom of the cutting component 4 and stop.

[0063] S7. Unload the cut pipe 7 and feed it onto the air shaft 23 located below the cutting assembly 4.
