Description

Technical Field

[0001] This utility model belongs to the field of furniture manufacturing technology, and specifically relates to a furniture manufacturing cutting and positioning mechanism. Background Technology

[0002] In the furniture manufacturing industry, sponge, as an important filling material, is widely used in the manufacture of furniture products such as sofas and mattresses due to its good flexibility, elasticity and comfort. The characteristics of sponge material enable it to provide support that conforms to the human body curves, improve the user experience, and make it an indispensable key material in modern furniture production.

[0003] In the sponge processing industry, vertical cutting machines are commonly used to cut large pieces of sponge into sponge blocks of the required size. However, existing vertical cutting machines suffer from inaccurate positioning of the sponge blocks during cutting. On the one hand, the soft texture of sponge makes it prone to displacement during cutting due to vibration or thrust generated by the downward pressure of the cutter, leading to dimensional deviations. On the other hand, traditional positioning methods cannot effectively coordinate with the downward pressure roller structure of the vertical cutting machine's cutter. The downward pressure roller may cause localized excessive compression and deformation of the sponge block when pressing down, affecting cutting quality and the yield of sponge blocks. Furthermore, existing positioning mechanisms cannot meet the rapid positioning needs of sponge blocks of different shapes and thicknesses, resulting in low cutting efficiency of the vertical cutting machine and making it unsuitable for large-scale production. These problems not only increase production costs but also limit the efficiency and quality improvement of furniture production. Therefore, there is an urgent need to develop a furniture production cutting and positioning mechanism that can effectively solve the above problems. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a furniture production cutting and positioning mechanism.

[0005] To achieve the above objectives, this utility model provides a furniture production cutting and positioning mechanism, including support boxes. Two sets of support boxes are provided, with rotating rollers rotatably connected to both sides of each support box. A conveyor belt is connected to the outer walls of the two rotating rollers. A material guide assembly is connected to the lower part of each support box. Support plates are connected to the middle of the upper ends of the two support boxes. A top box is connected to the upper end of the upper part of the two support plates. An electrically controlled slide rail is connected to the upper end of the inner wall of the top box. An electrically controlled slider is slidably connected to the lower end of the electrically controlled slide rail. A vertical cutting blade is connected to the middle of the lower end of the electrically controlled slider. Positioning components are connected to the middle of both sides of the top box. Each positioning component includes a fixed plate. An adjusting rod is rotatably connected to one side of the lower end of the fixed plate. A rotating rod is connected to one side of the adjusting rod. One end of the rotating rod extends through to one side of the adjusting rod. Pressure rollers are connected to both sides of the outer wall of the rotating rod. A stabilizing mechanism is connected to one side of the upper end of the adjusting rod.

[0006] In the above technical solution, the material guiding assembly further includes a connecting plate, a material guiding plate is rotatably connected between the two support boxes, the material guiding plate is located on one side of the conveyor belt, and a hydraulic cylinder is rotatably connected to one side of the connecting plate, with one end of the two hydraulic cylinders rotatably connected to the lower end of the material guiding plate.

[0007] In the above technical solution, a cylinder is rotatably connected to the other side of the lower end of the fixed plate, and a rotating block is connected to the lower end of the cylinder.

[0008] In the above technical solution, the rotating block is further configured in a C-shape, and both sides of the inner wall of the rotating block are connected to rotating shafts, with one end of each rotating shaft rotatably connected to the two sides of the adjusting rod.

[0009] In the above technical solution, the stabilizing mechanism further includes a frame, the lower end of which is connected to one side of the upper end of the adjusting rod, a connecting motor is connected to the middle of one side of the frame, the output end of the connecting motor is connected to a threaded rod, one end of the threaded rod extends through into the interior of the frame and is connected to one side of the inner wall of the frame, the threaded rod is provided with a bidirectional thread, and moving blocks are slidably connected to both sides of the outer wall of the threaded rod.

[0010] In the above technical solution, a fixed block is further connected to the middle of one side of the two movable blocks. One end of the fixed block extends through to one side of the frame. The fixed block is in the shape of an inverted L-shape. A fixing groove is opened on one side of the frame corresponding to the fixed block. The fixed block is slidably connected inside the fixing groove. A connecting slider is connected to the middle of the lower end of the fixed block.

[0011] In the above technical solution, a connecting ring is further connected below the connecting slider, and a groove is opened on the upper outer wall of the connecting ring corresponding to the connecting slider. The connecting slider slides inside the groove, and the cross-sectional shape of the connecting slider and the cross-sectional shape of the groove are both convex structures.

[0012] In the above technical solution, the lower end of the connecting ring is further connected to a housing, and electric telescopic rods are connected to both sides of the lower end of the inner wall of the housing. The output ends of the two electric telescopic rods extend through to the lower end of the housing, and clamps are connected to the lower ends of the two electric telescopic rods.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] The positioning components enhance the positioning accuracy and stability of the sponge block during the cutting process. The linkage design of the cylinder, rotating block, and adjusting rod allows the pressure roller to flexibly adjust its height and pressure according to the thickness of the sponge block. This avoids local deformation of the sponge block due to excessive pressure and ensures that the sponge block does not shift due to the vibration or thrust of the cutter during cutting. This keeps the cutting size deviation within a very small range, significantly improving cutting accuracy. Furthermore, the cooperation between the rotating rod and the pressure roller allows the pressure roller to roll freely with the cutting surface of the sponge block, reducing frictional resistance while continuously applying pressure and ensuring the smoothness of the cutting process. This lays a solid foundation for high-quality cutting operations.

[0015] The bidirectional threaded rod driven by the connecting motor can quickly adjust the lateral spacing of the clamping plates, meeting the clamping requirements of sponge blocks of different shapes and widths. The convex groove structure of the connecting slider and the connecting ring gives the clamping plates self-adjusting capability. When the height of the pressure roller changes and causes the angle of the adjusting rod to change, it ensures that the clamping plates are always perpendicular to the conveyor belt, stably clamping the sponge blocks from both sides. This effectively prevents the sponge blocks from shifting or deforming laterally during cutting, improving the cutting quality and yield of the sponge blocks, and making the equipment more adaptable to the needs of large-scale, high-efficiency furniture production.

[0025] To better understand the above-mentioned objectives, features and advantages of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0026] like Figures 1-8 The image shows a furniture production cutting and positioning mechanism. Example

[0027] The system includes two sets of support boxes 1. Rotary rollers are rotatably connected to both sides of each support box 1 to facilitate conveying by a conveyor belt 2. One end of one of the rollers extends into the interior of one of the support boxes 1. A drive motor is connected to one side of the inner wall of each support box 1 corresponding to the side of the roller. The output of the drive motor is connected to one end of the roller, facilitating the cutting of the sponge by the roller and conveyor belt 2. The outer walls of the two rollers are connected to the conveyor belt 2. A material guide assembly is connected at the bottom between the two support boxes 1. Support plates 6 are connected to the middle of the upper ends of the two support boxes 1. A top box 7 is connected to the upper end of the two support plates 6. An electrically controlled slide rail 8 is connected to the upper inner wall of the top box 7. The lower end of the 8 is slidably connected to an electrically controlled slider, which can drive the vertical cutter 9 to slide below the electrically controlled slide rail 8. The vertical cutter 9 is connected to the middle of the lower end of the electrically controlled slider. Positioning components are connected to the middle of both sides of the top box 7. The material guiding component includes a connecting plate 3. A guide plate 5 is rotatably connected between the two support boxes 1. The guide plate 5 is set in an inclined shape. Baffles are connected to both sides of the upper end of the guide plate 5. The baffles prevent the material from being discharged through the sides of the guide plate 5. The guide plate 5 is located on one side of the conveyor belt 2. A hydraulic cylinder 4 is rotatably connected to one side of the connecting plate 3. The tilt angle of the guide plate 5 can be adjusted by the hydraulic cylinder 4. One end of the two hydraulic cylinders 4 is rotatably connected to one side of the lower end of the guide plate 5.

[0028] The combination of the rotating roller and the conveyor belt 2 forms a continuous and stable material conveying channel, ensuring that the sponge block can enter the cutting area at a uniform speed and smoothly. The cooperation between the electrically controlled slide rail 8 and the electrically controlled slider gives the vertical cutter 9 precise lateral movement capability, which can realize flexible switching of different cutting paths and sizes. In the material guiding assembly, the inclined design of the guide plate 5 makes full use of the principle of gravity, so that the cut sponge block can automatically slide to the appropriate area. Example

[0029] The positioning assembly includes a fixed plate 10. An adjusting rod 11 is rotatably connected to one side of the lower end of the fixed plate 10. A rotating rod 14 is connected to one side of the adjusting rod 11. One end of the rotating rod 14 extends through to one side of the adjusting rod 11. Pressure rollers 15 are connected to both sides of the outer wall of the rotating rod 14. A stabilizing mechanism is connected to one side of the upper end of the adjusting rod 11. A cylinder 12 is rotatably connected to the other side of the lower end of the fixed plate 10. The cylinder 12 can drive the angle of the adjusting rod 11 to adjust the height of the pressure roller 15. The pressure roller 15 can press the sponge body above the conveyor belt 2. A rotating block 13 is connected to the lower end of the cylinder 12. The rotating block 13 is C-shaped. Rotating shafts are connected to both sides of the inner wall of the rotating block 13. One end of each rotating shaft is rotatably connected to both sides of the adjusting rod 11.

[0030] The rotating connection design between the adjusting rod 11 and the fixed plate 10, combined with the telescopic drive of the cylinder 12, enables flexible adjustment of the height position of the pressure roller 15, which can adapt to the positioning requirements of sponge blocks of different thicknesses. The rotating rod 14 passes through the structure of the adjusting rod 11, allowing the pressure roller 15 to rotate freely when rolling with the cut surface of the sponge block, reducing frictional resistance with the sponge surface, while maintaining a continuous and stable pressure output. The cylinder 12 is connected to the adjusting rod 11 through the rotating block 13. The C-shaped rotating block 13, combined with the structure design of the rotating shaft, allows the adjusting rod 11 to rotate at multiple angles within a certain range while transmitting the power of the cylinder 12, providing a reliable mechanical transmission guarantee for the precise positioning and pressure adjustment of the pressure roller 15. Example

[0031] The stabilizing mechanism includes a frame 16, the lower end of which is connected to one side of the upper end of the adjusting rod 11. A connecting motor 17 is connected to the middle of one side of the frame 16, and a threaded rod 18 is connected to the output end of the connecting motor 17. One end of the threaded rod 18 extends through into the interior of the frame 16 and connects to one side of the inner wall of the frame 16. The threaded rod 18 has a bidirectional thread. Moving blocks 19 are slidably connected to both sides of the outer wall of the threaded rod 18. A fixed block is connected to the middle of one side of each of the two moving blocks 19. One end of the fixed block extends through into one side of the frame 16. The fixed block has an inverted L-shaped structure, and a fixing groove is provided on one side of the frame 16 corresponding to the fixed block. The fixing block is slidably connected inside the fixing groove. A connecting slider 20 is connected to the middle of the lower end of the fixing block. A connecting ring 21 is connected below the connecting slider 20. A groove is opened on the upper outer wall of the connecting ring 21 corresponding to the connecting slider 20. The connecting slider 20 slides inside the groove. The cross-sectional shape of the connecting slider 20 and the cross-sectional shape of the groove are both convex structures. A housing 22 is connected to the middle of the lower end of the connecting ring 21. Electric telescopic rods 23 are connected to both sides of the lower end of the inner wall of the housing 22. The output ends of the two electric telescopic rods 23 extend through to the lower end of the housing 22. A clamping plate 24 is connected to the lower end of the two electric telescopic rods 23.

[0032] The frame 16 can move in real time following the height adjustment of the pressure roller 15. The design of the bidirectional threaded rod 18 driven by the motor 17 achieves the synchronous movement of the two moving blocks 19 in opposite directions through the ingenious thread transmission, thereby driving the fixed block to slide precisely in the fixed groove, completing the adjustment of the lateral spacing of the clamping plate 24 to adapt to the clamping requirements of sponge blocks of different widths. The convex sliding groove matching structure of the connecting slider 20 and the connecting ring 21 is the key to ensuring the vertical state of the clamping plate 24. When the height change of the pressure roller 15 causes the angle of the adjusting rod 11 to change, the gravity of the housing 22 and the clamping plate 24 will cause the connecting ring 21 to slide on the connecting slider 20. This adaptive adjustment mechanism ensures that no matter what position the pressure roller 15 is in, the clamping plate 24 can always be perpendicular to the conveyor belt 2, achieving stable and precise clamping of the two sides of the sponge, effectively preventing the sponge from lateral displacement during the cutting process.

[0033] Working principle: When using the device, the drive motor drives the rotating roller to rotate, which in turn starts the conveyor belt 2. The operator places the sponge block to be cut on the conveyor belt 2. The sponge block is conveyed to the cutting area by the conveyor belt 2. When the sponge block moves to the cutting area with the conveyor belt 2, the positioning component starts to work. The piston rod of the cylinder 12 extends and pushes the rotating block 13 to rotate around the connection point with the adjusting rod 11, thereby causing the adjusting rod 11 to swing downward, so that the pressure roller 15 gradually approaches and lightly presses on the upper surface of the sponge block. At this time, the connecting ring 21 is sleeved on the outer wall of the pressure roller 15 and can slide along the outer wall of the pressure roller 15. It can accurately adjust the pressure of the pressure roller 15 on the sponge block and make adaptive adjustments according to the height change of the sponge block to avoid local deformation of the sponge block due to excessive pressure.

[0034] The connecting motor 17 drives the threaded rod 18 with bidirectional threads to rotate, causing the two moving blocks 19 to move towards or away from each other on the threaded rod 18. This causes the fixed block to slide in the fixed groove on one side of the frame 16, realizing the lateral position adjustment of the connecting slider 20 and the connecting ring 21. When the height of the pressure roller 15 is adjusted, the angle position of one end of the adjusting rod 11 changes, which in turn causes the angle position of the housing 22 to change. Since the housing 22 and the clamping plate 24 have weight, under the action of gravity, the connecting ring 21 will move on the outer wall of the pressure roller 15 and the connecting slider 20. The sliding of block 20 under dual action, the convex structure design connecting slider 20 and slide groove, and the sliding of connecting ring 21 can ensure that housing 22 and clamping plate 24 are always perpendicular to conveyor belt 2, ensuring that clamping plate 24 can accurately clamp both sides of sponge no matter what height pressure roller 15 is at. According to the height of sponge block, the piston rod of electric telescopic rod 23 extends and pushes clamping plate 24 to move downward, so that the lower end of clamping plate 24 is at the same height as the sides of sponge block. After adjusting the two clamping plates 24 to the appropriate position, they clamp the two sides of the sponge block.

[0035] After the sponge block is stably positioned, the electronically controlled slide rail 8 controls the electronically controlled slider to drive the vertical cutter 9 to move laterally and cut the sponge block. During the cutting process, the pressure roller 15 continuously applies pressure to the upper surface of the sponge block, and the clamping action of the clamping plate 24 on both sides of the sponge block effectively limits the displacement of the sponge block caused by the vibration or thrust of the cutter, ensuring accurate cutting dimensions.

[0036] After cutting, the piston rod of cylinder 12 retracts, and the pressure roller 15 leaves the surface of the sponge block; the piston rod of electric telescopic rod 23 retracts, and clamping plate 24 releases its grip on the sponge block. The finished sponge block after cutting continues to be conveyed forward by conveyor belt 2. Since the guide plate 5 is set at an inclination, it will slide directly onto the guide plate 5 under the action of gravity and slide down to the collection area along the inclination angle of the guide plate 5.

Those skilled in the art should understand that this utility model is not limited to the above embodiments.
