Description

Technical Field

[0001] The invention belongs to the technical field of rubber processing, and more particularly relates to a rubber belt cutting mechanism and a rubber cutting machine. Background Art

[0002] Rubber is a type of highly elastic amorphous polymer material with reversible deformation capabilities. It can produce large deformations under small external forces at room temperature and quickly return to its original shape. It is widely used in industrial components such as tires, hoses, sealing rings and cable insulation layers.

[0003] During the production of rubber belts, due to process limitations, the edges of the initially formed strips often have burrs and irregular shapes. Therefore, a trimming mechanism is required to trim the edges of the strips to remove the irregular parts on both sides of the strips.

[0004] The scrap edge produced by cutting is in the form of a continuous strip. When the scrap edge is rolled up by the traction roller, the traction force acts on the scrap edge. The scrap edge and the main body of the strip are physically connected as a whole. Therefore, the tension borne by the scrap edge will be transmitted to the edge of the strip, causing the edge of the strip to wrinkle under the pulling, thus affecting the cutting effect. Summary of the Invention

[0005] The object of the present invention is to provide a rubber belt cutting mechanism and a rubber cutting machine, aiming to solve the pulling deformation of the edge of the belt blank caused by the traction force of the waste edge.

[0006] In a first aspect, the present invention provides a rubber belt cutting mechanism, which is arranged on a frame, and a roller for winding a belt blank is rotatably arranged on the frame, and the rubber belt cutting mechanism includes: Two cutting seats, respectively disposed on both sides of the frame and having elastic freedom to move toward the rotating roller; and Two pressing rollers are respectively rotatably arranged on the two cutting seats and abut against the strip blank; the pressing rollers are coaxially arranged with the rotating rollers and are rotated in the opposite direction to the rotating rollers by a driving member; The pressing roller has a cutting disc extending circumferentially and a cutting blade extending radially. The cutting disc is used to cut the edge of the strip to produce waste edges, and the cutting blade is used to cut the waste edges so that the waste edges are in the form of discontinuous strips.

[0007] In a possible implementation, two collecting boxes are slidably provided on the frame, and the two collecting boxes are respectively provided under the pressing roller in a one-to-one correspondence to receive the fallen waste edges; The side of the collection box is provided with an opening for discharging the waste edges, and a sealing plate is hingedly connected to the opening; The frame is provided with a control guide rail for controlling the opening and closing of the closing plate, the control guide rail extending along the moving direction of the collection box and always connected to the closing plate; the end of the control guide rail forms an upwardly curved extension path relative to the moving direction of the collection box; When the collecting box moves out from under the corresponding pressing roller, the sealing plate moves to the end of the control guide rail, and the control guide rail pushes the sealing plate to rotate, so that the sealing plate flips upward to open the opening.

[0008] In a possible implementation, the control guide rail has a direction-changing path, the direction-changing path is located at the end of the extension track of the control guide rail, and the direction-changing path is in an upwardly curved arc relative to the moving direction of the collection box; When the sealing plate moves along the direction-changing path, the control guide rail pushes the sealing plate to flip upward to open the opening.

[0009] In a possible implementation, the end of the sealing plate away from the hinge axis has an outwardly protruding extension, and the control guide rail includes: Two track ribs are arranged on the frame in an upper and lower arrangement and respectively abut against the upper and lower sides of the extension; a channel for the extension to slide is formed between the two track ribs.

[0010] In a possible implementation, slide grooves are provided on both sides of the collection box on the frame, and the collection box is slidably connected to the slide grooves; The chute has a first chute section and a second chute section, the first chute section is arranged horizontally, and the second chute section is arranged downwardly inclined; When the collecting box moves along the first slot section, the collecting box moves horizontally and is located below the corresponding pressing roller; when the collecting box moves along the second slot section, the collecting box moves out from below the corresponding pressing roller and the opening tilts downward.

[0011] In a possible implementation, the control guide rail has a first guide path, and the first guide path is horizontally arranged; When the collecting box moves along the first slot section, the sealing plate moves along the first guide path, and the control guide rail restricts the sealing plate from rotating so that the sealing plate always closes the opening.

[0012] In a possible implementation, the control guide rail has a second guide path, and the second guide path is in a downwardly curved arc shape; When the collecting box moves along the second slot section, the sealing plate moves along the second guide path, and the control guide rail restricts the sealing plate from rotating so that the sealing plate always closes the opening.

[0013] In a possible implementation, each of the collection boxes is slidably provided with a handle, and the sliding direction of the handle is perpendicular to the sliding direction of the corresponding collection box; A locking portion is fixedly provided on the handle, and a locking groove suitable for inserting the locking portion is provided on the frame; When the collection box moves to the position corresponding to the lower portion of the pressing roller, the locking portion can be inserted into the locking groove to fix the collection box.

[0014] In a possible implementation, a first support rod and a second support rod are fixedly provided on the frame, and the first support rod and the second support rod are both coaxially provided with the rotating roller; The two cutting seats are rotatably sleeved on the two ends of the first support rod respectively, and an elastic damping component is hinged between each cutting seat and the second support rod.

[0015] The rubber belt cutting mechanism provided by the present invention offers advantages over existing technologies in that the cutting disc on the pressure roller first cuts the edge of the strip, producing a continuous scrap edge. Simultaneously, the cutting blade extending radially from the pressure roller rotates with the roller, creating evenly spaced cuts in the scrap edge, transforming the scrap edge into independent short strips. These strips then fall directly under the action of gravity, eliminating the need for an additional traction device. This prevents the scrap edge from exerting traction on the strip, ensuring efficient cutting of the strip.

[0016] The cutting seat has elastic freedom towards the roller. When the strip thickness fluctuates, the pressure roller can float adaptively, ensuring that the cutting disc and the strip edge always maintain a stable cutting depth, avoiding over- or under-cutting caused by rigid contact, and reducing wrinkles caused by uneven force on the strip edge.

[0017] In a second aspect, the present invention further provides a rubber cutting machine comprising the above-mentioned rubber strip cutting mechanism.

[0018] The rubber cutting machine provided by the present invention, due to the adoption of the above-mentioned rubber strip cutting mechanism, can significantly improve the cutting accuracy and efficiency of the strip blank, eliminate the edge wrinkling problem caused by waste edge pulling, and ensure that the cutting edge is smooth.

DETAILED DESCRIPTION

[0022] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0023] See Figure 1 and Figure 2 The rubber belt cutting mechanism provided by the present invention is now described. The rubber belt cutting mechanism is arranged on a frame 1, on which a roller 3 for winding a strip 2 is rotatably arranged. The rubber belt cutting mechanism includes two cutting seats 4 and two pressing rollers 5.

[0024] Two cutting seats 4 are mounted on either side of the frame 1 and have elastic freedom to move toward the rotating roller 3. Two pressing rollers 5 are mounted on the cutting seats 4 in a one-to-one correspondence and in contact with the strip 2. The pressing rollers 5 are coaxial with the rotating roller 3 and are rotated in the opposite direction of the rotating roller 3 by a driving member 41.

[0025] The pressure roller 5 has a cutting disc 51 extending in the circumferential direction and a cutting blade 52 extending in the radial direction. The cutting disc 51 is used to cut the edge of the strip 2 to produce waste edges, and the cutting blade 52 is used to cut the waste edges so that the waste edges are in the form of discontinuous strips. The short waste strips fall directly under the action of gravity without the need for additional traction devices, thereby avoiding the waste edges from generating traction on the strip 2 and ensuring the cutting effect of the strip 2.

[0026] The cutting seat 4 has elastic freedom to move toward the rotating roller 3. When the thickness of the strip 2 fluctuates, the pressure roller 5 can adaptively adjust its position to ensure consistent contact between the pressure roller 5 and the strip 2, avoiding uneven cutting caused by rigid contact. The pressure roller 5 and the rotating roller 3 rotate coaxially and in opposite directions. The cutting disc 51 on the pressure roller 5 first cuts the edge of the strip 2 to produce a continuous scrap edge. Then, the radially extending cutting blade 52 cuts the continuous scrap edge into discrete strips.

[0027] When the strip 2 passes through the rotating roller 3 at a certain speed, the cutting disc 51 rotates with the pressure roller 5 to complete the initial cutting, and then the cutting blade 52 cuts off the waste edge. The waste edge cannot form a continuous pulling force to be transmitted to the edge of the strip 2, thereby effectively preventing the edge of the strip 2 from wrinkling due to the traction of the waste edge, ensuring that the edge of the rubber belt after cutting is flat and regular, and improving product quality.

[0028] Specifically, the driving member 41 is a motor, which is fixedly mounted on the cutting seat 4 , and an output end of the motor is connected to the pressing roller 5 , thereby driving the pressing roller 5 to rotate.

[0029] The cutting disc 51 on the pressure roller 5 first cuts the edge of the strip 2, producing a continuous scrap edge. Simultaneously, the cutting blade 52, extending radially from the pressure roller 5, rotates with the roller 5, creating evenly spaced cuts in the scrap edge, turning the scrap edge into independent short strips. These strips fall directly under the action of gravity, eliminating the need for additional traction devices. This prevents the scrap edge from exerting traction on the strip 2, ensuring the best possible cutting effect.

[0030] The cutting seat 4 has elastic freedom toward the roller 3. When the thickness of the strip 2 fluctuates, the pressure roller 5 can adaptively float, ensuring that the cutting disc 51 and the edge of the strip 2 always maintain a stable cutting depth, avoiding over- or under-cutting caused by rigid contact, and reducing wrinkles caused by uneven force on the edge of the strip 2.

[0031] In some embodiments, see Figure 1 and Figure 3 Two collection boxes 6 are slidably mounted on the frame 1. Each box 6 is positioned below the press rollers 5 to receive the fallen scrap. The sides of the boxes 6 have openings 61 for discharging the scrap, and a cover plate 62 is hingedly connected to the openings 61. Specifically, the openings 61 are located on the sides of the two boxes 6 facing away from each other.

[0032] See Figure 3 The frame 1 includes a control rail 11 for controlling the opening and closing of the sealing plate 62. The control rail 11 extends along the direction of movement of the collection box 6 and is always connected to the sealing plate 62. The end of the control rail 11 forms an upwardly curved extension path relative to the movement direction of the collection box 6. When the collection box 6 moves out from under the corresponding pressure roller 5, the sealing plate 62 moves to the end of the control rail 11, which pushes the sealing plate 62 to rotate, causing it to flip upward and open the opening 61.

[0033] The collecting box 6 is arranged below the pressing roller 5 and can promptly receive the waste edges generated by cutting. When the collecting box 6 is moved out from under the pressing roller 5, the sealing plate 62 automatically opens the opening 61 under the action of the control guide rail 11, making it convenient for the staff to take out the waste edges from the collecting box 6 for cleaning.

[0034] Specifically, there are two control rails 11 , and the two control rails 11 are respectively located on both sides of the collection box 6 .

[0035] It should be noted that when the sealing plate 62 closes the opening 61, it has an inclination toward the outside of the collection box 6. This makes it easy for the sealing plate 62 to be pushed by the control guide rail 11 and rotated away from the collection box 6 when the sealing plate 62 moves to the end part of the control guide rail 11, thereby avoiding jamming and ensuring the smooth opening of the sealing plate 62.

[0036] A worker pushes the collection box 6 away from the frame 1. During this movement, the collection box 6 gradually moves out from under the corresponding pressure roller 5, and simultaneously, the sealing plate 62 moves along the control rail 11. As the collection box 6 moves out from under the corresponding pressure roller 5, the sealing plate 62 also moves to the end of the control rail 11. At this point, as the collection box 6 continues to move, the upwardly curved structure at the end of the control rail 11 pushes the sealing plate 62 to rotate about the hinge axis, opening the opening 61 upward. This facilitates the discharge of scrap from the opening 61 under the action of gravity, eliminating the need for manual opening of the sealing plate 62 and dumping of the scrap. This simplifies the scrap handling process, improves scrap handling efficiency during the production process, and reduces manual intervention and labor intensity.

[0037] In some embodiments, see Figure 3 The control rail 11 has a turning path 111, which is located at the end of the extended track of the control rail 11. The turning path 111 is in an upwardly curved arc relative to the moving direction of the collection box 6. When the sealing plate 62 moves along the turning path 111, the control rail 11 pushes the sealing plate 62 to flip upward to open the opening 61.

[0038] The redirecting path 111 of the control guide rail 11 is in the shape of an upward curved arc. When the sealing plate 62 moves along the redirecting path 111, the sealing plate 62 can be flipped upward more smoothly to open the opening 61. Even if a lot of waste edges are accumulated in the collection box 6, the sealing plate 62 can be slowly opened under the guidance of the arc guide rail, ensuring that the waste edges are discharged smoothly and ensuring the fluency of waste edge processing.

[0039] In some embodiments, see Figure 4 The end of the cover plate 62 away from the hinge axis has an outwardly protruding extension 621. There are two extensions 621, one on each side of the cover plate 62, and the other extending toward the control rail 11. The control rail 11 includes two track ribs 112. The two track ribs 112 are arranged vertically on the frame 1 and respectively abut against the upper and lower sides of the extension 621. A channel is formed between the two track ribs 112 for the extension 621 to slide.

[0040] Furthermore, in order to ensure the smooth movement of the extension part 621 in the channel, a track roller (not shown in the figure) is rotatably provided on the extension part 621. The track roller can prevent the extension part 621 from getting stuck when moving in the channel, thereby ensuring the smooth rotation of the closing plate 62.

[0041] The extension 621 of the sealing plate 62 slides within the channel formed by the two track ribs 112, which precisely guide the extension 621. During the movement of the collection box 6, whether the sealing plate 62 is closing the opening 61 or opening the opening 61 under the control of the guide rail 11, the extension 621 can move stably along the predetermined path within the constraints of the track ribs 112, preventing the sealing plate 62 from deflecting or shaking.

[0042] In some embodiments, see Figure 3 and Figure 5 The frame 1 has chutes 12 on either side of the collection box 6, with the collection box 6 slidably connected to the chutes 12. The chutes 12 have a first slot section 121 and a second slot section 122. The first slot section 121 is horizontal, while the second slot section 122 is tilted downward. When the collection box 6 moves along the first slot section 121, it moves horizontally and is positioned below the corresponding pressure roller 5. When the collection box 6 moves along the second slot section 122, it moves out from under the corresponding pressure roller 5, with the opening 61 tilted downward.

[0043] For further information, see Figure 3 and Figure 5 Guide rollers 63 are rotatably provided on both sides of the collecting box 6 , and there are two guide rollers 63 on the same side. The guide rollers 63 are suitable for rolling in the chute 12 .

[0044] When the collection box 6 moves horizontally in the first slot section 121 of the chute 12, the collection box 6 remains in a horizontal position, which makes the waste edges in the collection box 6 more stable as the collection box 6 moves. When the collection box 6 moves in the second slot section 122 of the chute 12, the opening 61 tilts downward, causing the waste edges in the collection box 6 to gather toward the opening 61 under the action of gravity, which is more conducive to the rapid and complete discharge of the waste edges from the opening 61. The collection box 6 can efficiently complete the waste edge collection and discharge work, reduce the waste edges remaining in the box, and improve the practicality and operational convenience of the equipment.

[0045] In some embodiments, see Figure 3 The control guide rail 11 has a first guide path 113, which is horizontally arranged. When the collection box 6 moves along the first slot section 121, the sealing plate 62 moves along the first guide path 113, and the control guide rail 11 restricts the sealing plate 62 from rotating so that the sealing plate 62 always closes the opening 61.

[0046] When the collection box 6 is located below the corresponding pressure roller 5, the collection box 6 can receive the scraps that fall from the pressure roller 5. At this time, the sealing plate 62 is located in the first guide path 113. The sealing plate 62 cannot rotate due to the restriction of the control guide rail 11, thereby ensuring that the sealing plate 62 closes the opening 61, preventing the scraps from falling out of the collection box 6 and ensuring that all the scraps are collected in the collection box 6.

[0047] In some embodiments, see Figure 3 The control guide rail 11 has a second guide path 114 that is curved downward. When the collection box 6 moves along the second slot section 122, the sealing plate 62 moves along the second guide path 114. The control guide rail 11 restricts the sealing plate 62 from rotating so that the sealing plate 62 always closes the opening 61.

[0048] As the collection box 6 moves along the second trough section 122, the sealing plate 62 moves along the downwardly curved second guide path 114. The control rail 11 restricts the rotation of the sealing plate 62, keeping the opening 61 closed. As the collection box 6 moves out from under the pressure roller 5 and tilts, the sealing plate 62 always seals the opening 61, preventing waste from falling out of the opening 61 and contaminating the work environment. This also reduces cleanup work and improves work efficiency.

[0049] In some embodiments, see Figure 5 and Figure 6 Each collection box 6 is slidably provided with a handle 64, which slides perpendicularly to the direction of movement of the corresponding collection box 6. A locking portion 641 is fixedly provided on the handle 64, and a locking slot 13 is defined on the frame 1 for receiving the locking portion 641. When the collection box 6 is moved below the corresponding pressure roller 5, the locking portion 641 can be inserted into the locking slot 13, thereby securing the collection box 6.

[0050] When the collection box 6 moves below the pressure roller 5, the locking portion 641 on the handle 64 can be inserted into the locking groove 13 of the frame 1, thereby fixing the collection box 6. During the rubber strip cutting process, the collection box 6 remains stable and will not be displaced by the impact of falling scraps or vibrations of the frame 1. This ensures that the scraps fall into the collection box 6, ensuring smooth collection and preventing the movement of the collection box 6 from interfering with or damaging other components.

[0051] For further information, see Figure 6 , a magnet 65 is fixedly provided on the collection box 6, and an iron block 642 is fixedly provided on the handle 64. When the locking portion 641 is inserted into the locking groove 13, the magnet 65 and the iron block 642 are attracted.

[0052] When the collection box 6 moves to the bottom of the pressure roller 5, the locking part 641 on the handle 64 is inserted into the locking groove 13 of the frame 1. The mutual adsorption of the magnet 65 and the iron block 642 improves the stability of the locking part 641 in the locking groove 13, making it difficult for the locking part 641 to fall out of the locking groove 13, thereby ensuring the stability of the position of the collection box 6 and preventing the collection box 6 from slipping.

[0053] In some embodiments, see Figure 1 A first support rod 71 and a second support rod 72 are fixedly mounted on the frame 1. Both the first support rod 71 and the second support rod 72 are coaxially arranged with the rotating roller 3. Two cutting seats 4 are rotatably mounted on both ends of the first support rod 71. An elastic damping member 8 is hinged between each cutting seat 4 and the second support rod 72.

[0054] The cutting seat 4 is rotatably mounted on the first support rod 71 and hingedly connected to the second support rod 72 via an elastic damping member 8. The elastic damping member 8 absorbs vibration and impact forces generated during the conveyance of the strip 2, while also providing a buffer and stabilizing effect on the movement of the cutting seat 4. When the strip 2 fluctuates due to surface unevenness or other factors, the elastic damping member 8 limits excessive movement of the cutting seat 4, maintaining a relatively stable position. This ensures that the cutting disc 51 and cutting blade 52 on the pressure roller 5 can accurately cut the edges and waste of the strip 2, improving cutting stability and consistency, and ensuring the quality of the rubber belt.

[0055] For details, see Figure 2 The elastic damping member 8 includes a damping rod 81 and a spring 82. The outer cylinder portion of the damping rod 81 is hinged to the cutting seat 4, and the piston rod portion of the damping rod 81 is hinged to the second support rod 72. One end of the spring 82 is fixedly connected to the outer cylinder portion of the damping rod 81, and the other end of the spring 82 is fixedly connected to the piston rod portion of the damping rod 81.

[0056] In summary, the rubber strip cutting mechanism provided by the present invention, compared to the prior art, utilizes a cutting disc 51 on the pressure roller 5 to first cut the edge of the strip 2, producing a continuous scrap edge. Simultaneously, a cutting blade 52 extending radially from the pressure roller 5 rotates with the pressure roller 5, creating evenly spaced cuts in the scrap edge, transforming the scrap edge into individual short strips. These short strips then fall directly under gravity into a collection bin 6 for unified collection, eliminating the need for an additional traction device. This prevents the scrap edge from exerting traction on the strip 2, ensuring efficient cutting of the strip 2.

[0057] The cutting seat 4 is connected to the frame 1 via an elastic damping member 8, allowing it to move elastically toward the roller 3. When the thickness of the strip 2 fluctuates, the pressure roller 5 can adaptively float, ensuring that the cutting disc 51 and the edge of the strip 2 always maintain a stable cutting depth, avoiding over- or under-cutting caused by rigid contact and reducing wrinkles caused by uneven force on the edge of the strip 2.

[0058] By controlling the guide rails 11, when the collection box 6 moves below the pressure rollers 5, the sealing plate 62 closes the opening 61 to ensure that the scrap edges fall in properly. When the collection box 6 moves out from under the pressure rollers 5, the sealing plate 62 can flip upward and open, thereby facilitating the discharge of the scrap edges from the collection box 6. The entire process is highly automated, convenient, and labor-saving, reducing manual intervention. At the same time, the chute 12 controls the collection box 6, so that when the collection box 6 moves out from under the corresponding pressure roller 5, the opening 61 on the collection box 6 tilts downward. In conjunction with the opening 61 of the sealing plate 62, the scrap edges automatically slide out of the collection box 6 under the action of gravity, greatly reducing the labor intensity of the staff and simplifying the scrap edge dumping operation.

[0059] An embodiment of the present invention further provides a rubber cutting machine, which includes the above-mentioned rubber strip cutting mechanism.

[0060] The rubber cutting machine provided by the present invention, by employing the aforementioned rubber strip cutting mechanism, significantly improves the cutting accuracy and efficiency of the strip 2, eliminates edge wrinkles caused by scrap drag, and ensures a smooth cut edge. It also achieves automatic and convenient scrap collection and cleaning, reducing manual intervention. It also adapts to thickness fluctuations of the strip 2, maintaining stable and reliable cutting pressure.

[0061] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
