Technical Field
[0001] This application relates to the technical field of cutting machines, and in particular to a ring-belt cutting mechanism for a foam material cutting machine. Background Technology
[0002] Foamed materials are a type of material made from polyurethane slurry through a heated foaming process. They possess excellent properties such as lightweight, good elasticity, and heat and sound insulation, and are widely used in automotive interiors. Specifically, various interior components such as front and rear carpets, trunk liners, engine hoods, roof frames, and armrests are extensively manufactured using this type of foamed material, and it can adapt to the manufacturing needs of different types of automotive interior components.
[0003] To meet the processing requirements of foamed materials, the industry typically uses cutting machines to cut them. Existing foamed material cutting machines generally include a frame with a movable worktable on it to hold and transport the foamed material to be cut. A mounting bracket is also fixed to the frame, on which a cutter is mounted, and a drive assembly is installed on top of the mounting bracket to drive the cutter to complete the cutting action. However, the drive assembly of existing cutting machines mostly uses a cylinder to drive the cutter to move up and down reciprocally to achieve cutting. In actual operation, when processing thinner foamed material products, the force generated by the up-and-down movement of the cutter easily causes the thin products to bend and deform, making cutting difficult. This not only produces a large number of defective products but also severely reduces cutting efficiency, making it difficult to meet the demands of high-efficiency, high-quality production. Utility Model Content
[0004] In view of the above-mentioned prior art, in order to solve the problem that oil medium produces sludge due to high-temperature oxidation and impurity mixing during the riveting process, which leads to unstable riveting quality, this application provides a ring belt cutting mechanism for a foam material cutting machine.
[0005] This application provides a ring-belt cutting mechanism for a foam material cutting machine, which adopts the following technical solution:
[0006] A ring-belt cutting mechanism for a foam material cutting machine includes a frame, which includes a first vertical frame and a second vertical frame, spaced apart. A mounting block is disposed between the first and second vertical frames. A worktable is horizontally slidably mounted on the top of the mounting block. An upper housing is disposed on the top of the first vertical frame, and a first pulley is rotatably mounted inside the upper housing. A second pulley is rotatably mounted on one side of the mounting block. An annular steel belt is wound around the first and second pulleys. A through hole for the steel belt to pass through is provided at the bottom of the upper housing. A clearance groove for the annular steel belt to pass through is provided on the worktable. A gap for the annular steel belt to pass through is provided between the worktable and the first vertical frame. A driving component for driving the second pulley to rotate is also provided on the mounting block.
[0007] By adopting the above technical solution, a driving component can drive the second pulley to rotate, which, in conjunction with the first pulley, drives the annular steel belt in a cyclical motion. The worktable can slide horizontally on the mounting block, facilitating the transport of the foamed material to be cut. When the foamed material moves with the worktable to the annular steel belt, the cyclically moving steel belt passes through the clearance groove and gap, contacting and cutting the foamed material. Compared to the traditional cylinder-driven reciprocating cutting method, the cyclical motion of the annular steel belt generates a continuous and stable cutting force, without generating impact force, effectively preventing the thin foamed material from bending and deforming during cutting, thus ensuring cutting quality. Simultaneously, the continuous sliding of the worktable allows the cutting process to proceed continuously, improving cutting efficiency. The through-hole at the bottom of the upper housing guides the annular steel belt, ensuring a stable trajectory and further improving cutting accuracy.
[0008] Preferably, a limiting plate is provided on the worktable, and an adjustment component for adjusting the horizontal movement of the limiting plate is also provided on the worktable, wherein the movement direction of the worktable is perpendicular to the movement direction of the limiting plate.
[0009] By adopting the above technical solution, the limiting plate can effectively limit the movement of the foam material to be cut, preventing it from shifting during the sliding of the worktable and the cutting process, thus ensuring the accuracy of the cutting position. The adjusting component can adjust the horizontal position of the limiting plate, and the direction of movement of the limiting plate is perpendicular to the direction of movement of the worktable. This allows the operator to flexibly adjust the position of the limiting plate according to the size of the foam material, adapting to the cutting needs of foam materials of different specifications, and improving the versatility and applicability of the mechanism.
[0010] Preferably, the top of the mounting block is provided with two horizontally spaced slide rails, the length direction of the slide rails is perpendicular to the length direction of the first vertical frame, the worktable is provided with a slider for sliding and cooperating with the two slide rails, and the clearance groove on the worktable is opened along the sliding direction of the worktable.
[0011] By adopting the above technical solution, the sliding cooperation between the slide rail and the slider provides a stable guide for the horizontal sliding of the worktable, ensuring that the worktable can move smoothly along a fixed direction, reducing the shaking of the worktable during movement, and improving the cutting accuracy. The clearance groove is opened along the sliding direction of the worktable, which can better cooperate with the annular steel belt to cut the foam material, avoid interference from the clearance groove in the cutting process, and ensure the smooth progress of the cutting process.
[0012] Preferably, the adjusting assembly includes a connecting plate, a rack, and a rotating shaft. There are two racks, located on opposite sides of the limiting plate along its length and fixedly mounted on the worktable. Connecting blocks are provided at both ends of the racks along their length, and a sliding shaft is provided between the two connecting blocks. A linear bearing is slidably mounted on the sliding shaft. There are two connecting plates, located on opposite sides of the limiting plate along its length. One end of each connecting plate is fixedly connected to the limiting plate, and the end of each connecting plate away from the limiting plate is connected to the linear bearing. The rotating shaft passes through both connecting plates and is rotatably mounted on them. A gear corresponding to each of the two racks is provided on the rotating shaft, meshing with the racks. A rotating handle is provided at one end of the rotating shaft.
[0013] By adopting the above technical solution, when the handle is turned, the rotating shaft drives the gear to rotate. Since the gear meshes with the rack, the rotation of the gear is converted into the movement of the connecting plate, which in turn moves the limiting plate. The cooperation of the sliding shaft and linear bearing provides guidance and support for the movement of the connecting plate, making the movement of the limiting plate smoother and more stable. The arrangement of two racks and two connecting plates ensures that the limiting plate is subjected to uniform force during movement, avoiding tilting or jamming, guaranteeing the accuracy and stability of the limiting plate adjustment, and thus better achieving the limiting of the foamed material.
[0014] Preferably, a bushing is provided between the two connecting plates. The bushing is sleeved on the rotating shaft and fixedly connected to one side of the limiting plate. A locking element, which is a threaded rod, is provided on the bushing. A protrusion is provided on the protrusion, and a threaded hole is provided on the protrusion, which communicates with the inside of the bushing. A rotating handle is provided at one end of the threaded rod, and the end of the threaded rod away from the rotating handle passes through the threaded hole and abuts against the side wall of the rotating shaft.
[0015] By adopting the above technical solution, once the limiting plate is adjusted to the appropriate position, rotating the handle on the locking component allows the threaded rod to move along the threaded hole into the bushing and abut against the rotating shaft. Under the abutting action of the threaded rod, friction is generated between the rotating shaft and the bushing, which restricts the rotation of the rotating shaft. Furthermore, the meshing relationship between the gear and rack fixes the position of the connecting plate and the limiting plate, preventing the limiting plate from shifting due to external forces during the sliding of the worktable and cutting process. This ensures the stability and reliability of the limiting effect and helps improve cutting accuracy.
[0016] Preferably, the driving component is a drive motor, which is fixedly mounted on the first vertical frame. The output end of the drive motor is provided with a drive pulley, the second pulley is a double-groove pulley, and a synchronous belt is sleeved between the drive pulley and the second pulley.
[0017] By adopting the above technical solution, the drive motor drives the second pulley (double-grooved pulley) to rotate through the cooperation of the drive pulley and the synchronous belt. Synchronous belt drive features accurate transmission ratio, smooth transmission, and low noise, ensuring stable rotational speed of the second pulley and thus maintaining uniform cyclic speed of the annular steel belt. The double-grooved design of the second pulley increases the contact area between the synchronous belt and the pulley, improving transmission reliability and reducing slippage. Stable transmission helps avoid decreased cutting accuracy due to speed fluctuations of the annular steel belt during cutting, ensuring the smoothness of the cut edges of the thin foamed material.
[0018] Preferably, the bottom of the upper housing is provided with a connecting shaft, and the end of the connecting shaft away from the upper housing is provided with a limiting piece. The limiting piece has a limiting hole for the annular steel belt to pass through. The upper housing is also provided with a lifting component for raising and lowering the connecting shaft.
[0019] By adopting the above technical solution, the limiting holes on the limiting plate can constrain and guide the annular steel strip, preventing lateral displacement or swaying during its cyclic movement, ensuring the stability of its motion trajectory, and improving cutting accuracy. The lifting component can adjust the height of the connecting shaft and the limiting plate, allowing the limiting plate to adapt to the cutting needs of foam materials of different thicknesses. When cutting materials of different thicknesses, the height of the limiting plate can be adjusted to ensure that the annular steel strip is always in the optimal cutting position, improving the versatility of the mechanism.
[0020] Preferably, the lifting component is a hollow tube with open ends along its length. The hollow tube is vertically installed inside the upper housing. The end of the connecting shaft away from the limiting piece passes through the bottom of the upper housing and is slidably installed inside the hollow tube. A threaded through hole is provided on the outer wall of the hollow tube, and a bolt is inserted into the threaded through hole. One end of the bolt passes through the threaded through hole and abuts against the connecting shaft.
[0021] By adopting the above technical solution, the hollow tube provides guidance and support for the lifting and lowering of the connecting shaft, making the lifting and lowering movement of the connecting shaft smoother. When it is necessary to adjust the height of the connecting shaft and the limiting plate, loosening the bolts allows the connecting shaft to slide inside the hollow tube. After adjusting to the appropriate height, tightening the bolts makes the bolts abut against the connecting shaft, thus fixing the position of the connecting shaft. The operation is simple and convenient. This structural design not only realizes the flexible adjustment of the height of the limiting plate, but also ensures the stability after adjustment, ensuring that the limiting plate's constraint effect on the annular steel belt is reliable and effective.
[0022] In summary, this application includes at least one of the following beneficial technical effects:
[0023] 1. By setting up a driving component, the second pulley can be driven to rotate, which, in conjunction with the first pulley, drives the annular steel belt to perform a cyclical motion. The worktable can slide horizontally on the mounting block, facilitating the transport of the foam material to be cut. When the foam material moves with the worktable to the annular steel belt, the cyclically moving steel belt passes through the clearance groove and gap, contacting and cutting the foam material. Compared to the traditional cylinder-driven reciprocating cutting method, the cyclical motion of the annular steel belt generates a continuous and stable cutting force, without generating impact force, effectively preventing the thin foam material from bending and deforming during cutting, ensuring cutting quality. At the same time, the continuous sliding of the worktable allows the cutting process to continue continuously, improving cutting efficiency; the through holes at the bottom of the upper housing can guide the annular steel belt to ensure its stable movement trajectory, further improving cutting accuracy.
[0024] 2. The limiting plate, by setting a limit plate, can limit the foam material to be cut, preventing it from shifting during the sliding of the worktable and the cutting process, thus ensuring the accuracy of the cutting position. The adjustment component can adjust the horizontal position of the limiting plate, and the movement direction of the limiting plate is perpendicular to the movement direction of the worktable. This allows the operator to flexibly adjust the position of the limiting plate according to the size of the foam material, so as to meet the cutting needs of different specifications of foam materials, thereby improving the versatility and applicability of the mechanism.
[0025] 3. When the handle is turned, the rotating shaft drives the gear to rotate. Since the gear meshes with the rack, the rotation of the gear translates into movement of the connecting plate, which in turn moves the limiting plate. The cooperation of the sliding shaft and linear bearing provides guidance and support for the movement of the connecting plate, making the movement of the limiting plate smoother and more stable. The arrangement of two racks and two connecting plates ensures that the limiting plate is subjected to even force during movement, preventing tilting or jamming, guaranteeing the accuracy and stability of the limiting plate adjustment, and thus better limiting the foam material.

[0030] The following is in conjunction with the appendix Figure 1-3 This application will be described in further detail.
[0031] This application discloses a ring-belt cutting mechanism for a foam material cutting machine.
[0032] Reference Figure 1 and Figure 2 A ring-belt cutting mechanism for a foam material cutting machine includes a frame 1 and a worktable 2. The worktable 2 is horizontally slidably mounted on the frame 1. A first pulley 3 is provided at the top of the frame 1, and a second pulley 4 is provided at the bottom of the frame 1. The worktable 2 is located between the first pulley 3 and the second pulley 4. An annular steel belt 5 is also wound around the first pulley 3 and the second pulley 4. An obstacle groove 21 is provided on the worktable 2 for the annular steel belt 5 to pass through. A driving component 6 for driving the second pulley 4 to rotate is also provided on the frame 1.
[0033] During operation, the drive unit 6 starts and drives the second pulley 4 to rotate. With the cooperation of the first pulley 3, the annular steel belt 5, wound around the two pulleys, circulates. At this time, the thin foam material to be cut is placed on the worktable 2, which slides horizontally along the frame 1, causing the foam material to gradually approach the annular steel belt 5. The worktable 2 is located between the first pulley 3 and the second pulley 4, and it has a clearance groove 21. When the foam material moves with the worktable 2 to the annular steel belt 5, the circulating steel belt 5 passes through the clearance groove 21 and contacts the foam material. The circulating motion of the annular steel belt 5 generates a continuous cutting force, enabling it to smoothly cut into the interior of the foam material.
[0034] During the cutting process, the annular steel belt 5 maintains a continuous cyclical motion, unlike traditional cylinder-driven cutters which generate reciprocating impact forces. This stable cutting method effectively prevents thin foam materials from bending and deforming due to stress, ensuring that the foam material remains flat during cutting. Simultaneously, the worktable 2 continuously slides horizontally to transport the foam material, enabling a continuous cutting process and achieving efficient and precise cutting of thin foam materials.
[0035] Specifically, the frame 1 includes a first vertical frame 11 and a second vertical frame 12, which are spaced apart. The height of the first vertical frame 11 is higher than that of the second vertical frame 12. A mounting block 7 is fixedly installed between the first vertical frame 11 and the second vertical frame 12. The height of the mounting block 7 is flush with that of the second vertical frame 12. Two slide rails 8 are spaced apart on the top of the mounting block 7. The length direction of the two slide rails 8 is perpendicular to the length direction of the first vertical frame 11. A slider 22 is provided on the bottom surface of the worktable 2 to slide and cooperate with the two slide rails 8. A gap is formed between the worktable 2 and the first vertical frame 11 for the annular steel belt 5 to pass through. A limiting plate 9 for limiting the foaming material is provided on the top surface of the worktable 2.
[0036] Furthermore, the limiting plate 9 is slidably disposed on the top surface of the worktable 2, and the worktable 2 is also provided with an adjustment component 10 for adjusting the sliding of the limiting plate 9, and the moving direction of the limiting plate 9 is perpendicular to the moving direction of the worktable 2.
[0037] Reference Figure 1 and reference Figure 3 The adjustment assembly 10 includes a connecting plate 101, a rack 102, and a rotating shaft 103. Two racks 102 are provided, located on both sides of the limiting plate 9 along the length direction and fixedly installed on the worktable 2. Connecting blocks 1021 are provided at both ends of the rack 102 along the length direction. A sliding shaft 1022 is horizontally arranged between the two connecting blocks 1021. The sliding shaft 1022 is located on the side of the rack 102 away from the worktable 2, and a linear bearing 1023 is sleeved on the sliding shaft 1022. The linear bearing 1023 is slidably arranged on the sliding shaft 1022. There are two connecting plates 101, which are located on both sides of the limiting plate 9 along the length direction. One end of the connecting plate 101 is fixedly connected to the limiting plate 9 with bolts, and the end of the connecting plate 101 away from the limiting plate 9 is fixedly connected to the linear bearing 1023. One end of the rotating shaft 103 is provided with a rotating handle 1031, and the end of the rotating shaft 103 away from the rotating handle 1031 passes through the two connecting plates 101. Two gears 1032 are provided on the rotating shaft 103, which correspond one-to-one with the two racks 102, and the gears 1032 mesh with the racks 102.
[0038] When limiting the movement of the foam material, the operator can turn the handle 1031 to drive the rotating shaft 103 to rotate synchronously. The two gears 1032 on the rotating shaft 103 mesh with the two racks 102 on the worktable 2. Under the meshing transmission action of the gears 1032 and racks 102, the rotating shaft 103 will drive the two connecting plates 101 connected to it to move. At this time, the end of the connecting plate 101 away from the limiting plate 9 is fixedly connected to the linear bearing 1023 sleeved on the sliding shaft 1022. Driven by the connecting plate 101, the linear bearing 1023 will slide along the sliding shaft 1022, providing guidance for the movement of the limiting plate 9 and ensuring that the limiting plate 9 can slide smoothly in a direction perpendicular to the movement of the worktable 2. As the limiting plate 9 moves, the operator can adjust the limiting plate 9 to a suitable position according to the size of the foam material to be cut. When the limiting plate 9 comes into contact with the side of the foam material, stop rotating the handle 1031. At this time, the limiting plate 9 can effectively limit the foam material and prevent the foam material from deviating during the sliding and cutting process of the worktable 2.
[0039] Furthermore, a bushing 14 is provided between the two connecting plates 101. The bushing 14 is sleeved on the rotating shaft 103 and is fixedly connected to the limiting plate 9. A locking element 15 is provided on the bushing 14. The locking element 15 is a threaded rod 151. A protrusion 141 is provided on the bushing 14. A threaded hole communicating with the inside of the bushing 14 is opened on the protrusion 141. A rotating handle 1031 is provided at one end of the threaded rod 151. The end of the threaded rod 151 away from the rotating handle 1031 passes through the threaded hole and abuts against the side wall of the rotating shaft 103.
[0040] When the limiting plate 9 is adjusted, the operator can rotate the rotating handle 1031 on the threaded rod 151, causing the threaded rod 151 to move along the threaded hole on the protrusion 141 into the bushing 14. The end of the threaded rod 151 away from the rotating handle 1031 passes through the threaded hole and faces the side wall of the rotating shaft 103. As the threaded rod 151 continues to move, its end gradually abuts against the side wall of the rotating shaft 103. Under the abutting force of the threaded rod 151, friction is generated between the rotating shaft 103 and the bushing 14, thereby restricting the rotation of the rotating shaft 103. Since both ends of the bushing 14 are fixedly connected to the two connecting plates 101, after the rotation of the rotating shaft 103 is restricted, the positions of the connecting plates 101 and the limiting plate 9 are also fixed through the meshing relationship between the gear 1032 and the rack 102, and will no longer move. In this way, the limiting plate 9 can be stably kept in contact with the side of the foam material. Even if it is affected by external force during the sliding of the worktable 2 and the cutting of the annular steel strip 5, there will be no positional deviation. This further ensures the limiting effect on the foam material and ensures that the cutting work can be carried out accurately and stably.
[0041] The driving component 6 is a drive motor 61, which is fixedly installed at the bottom of the first vertical frame 11. A drive pulley 611 is provided at the output end of the drive motor 61. The second pulley 4 is a double-grooved pulley, and a synchronous belt 612 is wound between the drive pulley 611 and the second pulley 4. The drive motor 61 drives the double-grooved pulley (second pulley 4) to rotate via the synchronous belt 612. The synchronous belt 612 transmission has the characteristics of accurate transmission ratio and smooth operation, ensuring the stable rotational speed of the second pulley 4, thereby maintaining a uniform cyclic speed of the annular steel belt 5. This stable driving method can avoid the decrease in cutting accuracy caused by fluctuations in the steel belt speed during the cutting process, ensuring a smooth cut of the thin foam material.
[0042] Specifically, the top of the first vertical frame 11 is provided with an upper housing 16, and the first pulley 3 is rotatably installed inside the upper housing 16. The bottom wall of the upper housing 16 has a through hole for the annular steel belt 5 to pass through. The bottom of the upper housing 16 is provided with a connecting shaft 17, and the end of the connecting shaft 17 away from the upper housing 16 is provided with a limiting piece 18, and the limiting piece 18 has a limiting hole 181 for the annular belt to pass through. The upper housing 16 is also provided with a lifting component 19 for raising and lowering the connecting shaft 17. The lifting component 19 is a hollow tube 19. 1. The hollow tube 191 is located inside the upper housing 16. The hollow tube 191 is vertically installed inside the upper housing 16. Both ends of the hollow tube 191 in the vertical direction are open and connected to the interior of the hollow tube 191. The end of the connecting shaft 17 away from the limiting plate 18 passes through the bottom of the upper housing 16 and is slidably installed inside the hollow tube 191. A threaded through hole is opened on the side wall of the hollow tube 191, and a bolt is inserted into the threaded through hole. One end of the bolt passes through the threaded through hole and abuts against the side wall of the connecting shaft 17. The limiting hole 181 on the limiting plate 18 can constrain the annular steel strip 5, so that it maintains a stable trajectory during the cyclic movement and avoids lateral displacement or shaking due to high-speed movement or cutting force.
[0043] The implementation principle of this application embodiment is as follows: After the drive motor 61 is started, the second pulley 4 is driven to rotate through the synchronous belt 612, so that the annular steel belt 5 wrapped around the first pulley 3 and the second pulley 4 forms a stable cyclic motion, and the annular steel belt 5 maintains a stable trajectory with the cooperation of the through hole of the upper box 16, the limiting hole 181 of the limiting plate 18 and the clearance groove 21 of the worktable 2; the thin foam material is placed on the worktable 2, and the limiting plate 9 is adjusted by the adjusting component 10 and fixed by the locking component 15 to achieve precise positioning of the material. Then the worktable 2 slides horizontally along the slide rail 8 to transport the material; when the material comes into contact with the cyclically moving annular steel belt 5, the steel belt completes the cutting with a continuous and stable cutting force. During this period, because there is no impact force and the material is reliably limited, deformation can be avoided. At the same time, the height of the limiting plate 18 can be adjusted by the lifting component 19 to adapt to materials of different thicknesses. Finally, through the synergistic effect of the various structures, efficient and precise cutting of thin foam material is achieved.
[0044] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
