Description

Technical Field

[0001] This invention belongs to the field of furniture production equipment technology, and more specifically, relates to a furniture forming mold. Background Technology

[0002] PE wood-plastic composite material is a new type of composite material that has emerged rapidly in recent years both domestically and internationally. It refers to composite material particles prepared by mixing polyethylene with plant fibers such as wood powder, rice husk, and bamboo powder to form new wood-based materials, and then blending and granulating them. It is a raw material for producing furniture boards, profiles, and other materials. Its production equipment mainly consists of furniture molding molds.

[0003] Current furniture molding dies include an extruder and a cutting mechanism. First, the material is extruded through the extruder head, and then the surface is patterned using a wood grain roller. After reaching a certain point, it is cut. The cutting mechanism on the existing molding die is fixed. During cutting, the front extruder needs to stop extruding so that the cutting mechanism can cut the material. Then the extrusion process continues. Because the extruder stops and starts repeatedly, the raw material accumulates inside, resulting in uneven wood-plastic composite boards after extrusion. In severe cases, it can even cause equipment blockage and damage. Summary of the Invention

[0004] The purpose of this invention is to provide a furniture molding die, which aims to solve the problem that the extruder in existing furniture molding dies needs to be stopped and started repeatedly, which causes the raw material to accumulate inside, resulting in uneven wood-plastic composite boards after extrusion molding, and in severe cases, it can also cause equipment blockage and damage.

[0005] To achieve the above objectives, the technical solution adopted by the present invention is as follows: A furniture forming mold is provided, comprising a worktable, an extruder, and a cutting mechanism; characterized in that a slide rail is fixedly installed on the worktable, the slide rail being arranged along the conveying direction of the wood-plastic composite board on one side of the extrusion head of the extruder; the cutting mechanism includes a support and a cutting component, the bottom of the support being slidably disposed on the slide rail, the support being able to move synchronously with the wood-plastic composite board on the slide rail, the cutting component being installed on the support, the cutting component having a degree of freedom of movement in the vertical direction, and the cutting component being used to cut the wood-plastic composite board.

[0006] In one possible implementation, the bottom of the bracket is equipped with rollers, and the top surface of the slide rail is provided with a groove that matches the rollers.

[0008] In one possible implementation, a screw parallel to the guide rod is rotatably mounted on the bracket, a nut threadedly connected to the screw is fixedly mounted on the tool holder, and a drive component for driving the screw to rotate is provided on the bracket.

[0009] In one possible implementation, the driving component is a servo motor, and the output shaft of the servo motor is fixedly connected to the screw.

[0010] In one possible implementation, a connecting rod is fixedly mounted on the guide rod, a vertical rack is fixedly mounted on the connecting rod, the vertical rack is arranged parallel to the guide rod, and a driven gear that meshes with the vertical rack is fixedly mounted on the rotating shaft of the blade.

[0011] In one possible implementation, a protective plate is slidably disposed on the blade holder; the protective plate has a degree of freedom of movement in the vertical direction, and the protective plate is located outside the blade; a compression spring is installed between the blade holder and the protective plate, and the compression spring is used to apply a downward force to the protective plate.

[0012] In one possible implementation, a baffle is fixedly mounted on the bracket, and the baffle abuts against the end face of the free end of the wood-plastic composite board.

[0013] In one possible implementation, a support shaft is fixedly mounted on the worktable, the support shaft is perpendicular to the slide rail, the support shaft is located on the side of the bracket closer to the extruder, a take-up roller is fitted on the support shaft, a torsion spring is installed between the take-up roller and the support shaft, a rope is wound on the take-up roller, and one end of the rope is fixed to the bracket.

[0014] In one possible implementation, the workbench is equipped with transfer rollers for conveying wood-plastic composite boards.

The slide rail is located on one side of the extrusion head of the extruder and is arranged along the transmission direction of the wood-plastic composite board. The cutting mechanism includes a bracket and a cutting component. The bottom of the bracket is slidably mounted on the slide rail, and the cutting component is mounted on the bracket and has the freedom to move in the vertical direction. The extruder drives the cutting mechanism to move synchronously with the wood-plastic composite board, and at the same time, the cutting component moves in the vertical direction towards the side closer to the wood-plastic composite board, thereby completing the cutting of the wood-plastic composite board.

[0025] To make the technical problems to be solved, the technical solutions, and the beneficial effects of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and are not intended to limit the present invention.

[0026] Please refer to the following: Figures 1 to 2 The present invention will now describe a furniture forming mold. A furniture forming mold includes a worktable 1, an extruder 2, and a cutting mechanism. A slide rail 101 is fixedly installed on the worktable 1, and the slide rail 101 is arranged along the conveying direction of the wood-plastic composite board 4 on one side of the extrusion head 201 of the extruder 2. The cutting mechanism includes a support 501 and a cutting component 502. The bottom of the support 501 is slidably disposed on the slide rail 101, and the support 501 can move synchronously with the wood-plastic composite board 4 on the slide rail 101. The cutting component 502 is installed on the support 501 and has a degree of freedom of movement in the vertical direction. The cutting component 502 is used to cut the wood-plastic composite board 4.

[0027] This embodiment provides a furniture forming mold. Compared with the prior art, a slide rail 101 is fixedly installed on the workbench 1. The slide rail 101 is located on one side of the extrusion head 201 of the extruder 2. The slide rail 101 is arranged along the transmission direction of the wood-plastic composite board 4. The cutting mechanism includes a bracket 501 and a cutting component 502. The bottom of the bracket 501 is slidably mounted on the slide rail 101. The cutting component 502 is mounted on the bracket 501 and has the freedom to move in the vertical direction. The extruder 2 drives the cutting mechanism to move synchronously with the wood-plastic composite board 4. At the same time, the cutting component 502 moves in the vertical direction towards the side closer to the wood-plastic composite board 4, thereby completing the cutting of the wood-plastic composite board 4. Since the cutting component 502 moves synchronously with the wood-plastic composite board 4, the extruder 2 does not need to be stopped. Therefore, the raw material will not accumulate in the extruder 2, ensuring the flatness of the wood-plastic composite board 4 after extrusion molding, and avoiding blockage and damage to the equipment.

[0028] In this embodiment, the extruder 2 provides the power to forward transport the formed wood-plastic composite board 4.

[0029] In some embodiments, please refer to Figures 1 to 3 The bottom of the support 501 is equipped with rollers 503, and the top surface of the slide rail 101 is provided with a groove 102 that matches the rollers 503. In this embodiment, there are two slide rails 101, which are arranged in parallel on the worktable 1. The bottom of the support 501 is equipped with four rollers 503, with two rollers 503 corresponding to each slide rail 101. The top surface of the slide rail 101 is provided with a groove 102, and the rollers 503 slide within the groove 102. The rollers 503 and the slide rail 101 have sliding friction, which greatly reduces frictional resistance and makes the support 501 move more smoothly on the slide rail 101.

[0030] In some embodiments, please refer to Figure 1 , Figure 2 , Figure 4 , Figure 5 and Figure 6 The cutting assembly 502 includes a blade holder 504 and a blade 505. A guide block 506 is fixedly mounted on the blade holder 504. A guide rod 507 is fixedly mounted on the bracket 501. The guide rod 507 is arranged vertically and slides in cooperation with the guide block 506. The blade 505 is rotatably mounted on the bottom of the blade holder 504. In this embodiment, the cutting assembly 502 is located directly above the wood-plastic composite board 4. Two guide blocks 506 are fixedly mounted on the top of the blade holder 504, and the two guide blocks 506 are symmetrically arranged on both sides of the blade holder 504. A guide rod 507 is fixedly mounted vertically on the bracket 501, and a through hole is provided on the guide block 506 to slide in cooperation with the guide rod 507. Through the cooperation of the guide block 506 and the guide rod 507, the blade holder 504 can move vertically relative to the bracket 501. The blade 505 is rotatably mounted on the bottom of the blade holder 504. The axis of rotation of the blade 505 is parallel to the length direction of the slide rail 101. The blade holder 504 will drive the blade 505 to move downwards, and the blade 505 will rotate, thereby cutting the wood-plastic composite board 4.

[0031] In some embodiments, please refer to Figure 1 , Figure 2 , Figure 4 , Figure 5 and Figure 6 A screw 508, parallel to a guide rod 507, is rotatably mounted on a bracket 501. A nut 509, threadedly connected to the screw 508, is fixedly mounted on a tool holder 504. A driving component 510 for driving the screw 508 to rotate is provided on the bracket 501. In this embodiment, the upper end of the screw 508 is rotatably connected to the bracket 501, and the screw 508 remains parallel to the guide rod 507. The nut 509 is fixedly mounted on the tool holder 504, and the nut 509 is threadedly connected to the screw 508. The nut 509 is located between the two guide rods 507. The driving component 510 on the bracket 501 drives the screw 508 to rotate, and the screw 508, through the nut 509, drives the tool holder 504 to move up and down vertically.

[0032] In some embodiments, please refer to Figure 4 The driving component 510 is a servo motor, and the output shaft of the servo motor is fixedly connected to the screw 508. In this embodiment, the output shaft of the servo motor and the screw 508 are coaxial, and the output shaft of the servo motor and the screw 508 are connected by a coupling. When the output shaft of the servo motor rotates forward, it drives the cutting component 502 to move downward; when the output shaft of the servo motor rotates in reverse, it drives the cutting component 502 to move upward.

[0033] In some embodiments, please refer to Figure 1 , Figure 2 , Figure 4 , Figure 5 and Figure 6 A connecting rod 511 is fixedly mounted on the guide rod 507, and a vertical rack 512 is fixedly mounted on the connecting rod 511. The vertical rack 512 is arranged parallel to the guide rod 507, and a driven gear 513 that meshes with the vertical rack 512 is fixedly mounted on the rotating shaft of the blade 505. In this embodiment, the connecting rod 511 is fixedly connected to two guide rods 507 respectively, and the vertical rack 512 is fixedly mounted on the bottom of the connecting rod 511. The vertical rack 512 is arranged in the vertical direction and meshes with the driven gear 513 on the rotating shaft of the blade 505. When the cutting assembly 502 moves vertically relative to the bracket 501, the vertical rack 512 drives the blade 505 to rotate through the driven gear 513, thereby completing the cutting operation of the wood-plastic composite board 4. The ratio of the diameter of the driven gear 513 to the diameter of the blade 505 is 1:6, thereby providing the blade 505 with a faster rotation speed.

[0034] In some embodiments, please refer to Figures 1 to 7A protective plate 514 is slidably mounted on the blade holder 504; the protective plate 514 has a degree of freedom to move in the vertical direction, and is located outside the blade 505; a compression spring 515 is installed between the blade holder 504 and the protective plate 514, and the compression spring 515 is used to apply a downward force to the protective plate 514. In this embodiment, the outer contour of the protective plate 514 is larger than the outer contour of the blade 505, and the protective plate 514 is located on the side of the blade 505 away from the extruder 2. The servo motor rotates forward, driving the cutting assembly 502 downward. The protective plate 514 first contacts the wood-plastic composite board 4 to be cut. The blade holder 504 drives the blade 505 to continue moving downward and cutting the wood-plastic composite board 4. The compression spring 515 is compressed and deformed, applying a downward force to the protective plate 514. After the blade 505 cuts the wood-plastic composite board 4, the cut wood-plastic composite board 4 falls downward under the action of the protective plate 514. The servo motor rotates in reverse, driving the cutting assembly 502 upward, moving the blade 505 above the wood-plastic composite board 4. Then, the bracket 501 moves back to its original position in the opposite direction of the wood-plastic composite board 4's transport direction, facilitating the next cutting operation. The protective plate 514 not only allows the cut wood-plastic composite board 4 to quickly detach from the overall wood-plastic composite board 4, but also prevents the operator from accidentally touching the blade 505, improving the safety factor. A guide post 516 is fixedly installed on the protective plate 514, and a guide groove 517 correspondingly is provided on the tool holder 504 to slide and engage with the guide post 516. There are two guide posts 516, both horizontally aligned and parallel. The guide groove 517 is vertically aligned. A limit post 518 is fixedly installed on the guide post 516, perpendicular to it. A limit groove 519 correspondingly is provided on the tool holder 504 to slide and engage with the limit post 518, parallel to the guide groove 517.

[0035] In some embodiments, please refer to Figure 1 , Figure 2 and Figure 4A baffle 520 is fixedly installed on the support 501, and the baffle 520 abuts against the end face of the free end of the wood-plastic composite board 4. In this embodiment, the baffle 520 and the support 501 are detachably connected by fasteners. During the forward transmission of the wood-plastic composite board 4, the free end face of the wood-plastic composite board 4 abuts against the baffle 520, and then drives the support 501 to slide on the slide rail 101. During the synchronous movement of the support 501 with the wood-plastic composite board 4, the cutting component 502 cuts the wood-plastic composite board 4 with the blade 505. The protective plate 514 applies a downward force to the cut wood-plastic composite board 4, thereby overcoming the frictional resistance between the cut wood-plastic composite board 4 and the baffle 520 and the blade 505, so that the cut wood-plastic composite board 4 can fall smoothly downward. A conveyor belt 6 is installed below the workbench 1. The workbench 1 has a clearance groove corresponding to the conveyor belt 6, so that the cut wood-plastic composite board 4 can fall onto the conveyor belt 6. The conveyor belt 6 will transport the cut wood-plastic composite board 4 to the next process.

[0036] In some embodiments, please refer to Figures 1 to 4 A support shaft 103 is fixedly installed on the workbench 1, perpendicular to the slide rail 101. The support shaft 103 is located on the side of the bracket 501 near the extruder 2. A take-up roller 104 is mounted on the support shaft 103, and a torsion spring 105 is installed between the take-up roller 104 and the support shaft 103. A rope 106 is wound on the take-up roller 104, and one end of the rope 106 is fixed to the bracket 501. In this embodiment, the support shaft 103 is fixedly installed on the workbench 1 in a horizontal direction, perpendicular to the transmission direction of the wood-plastic composite board 4. The take-up roller 104 is rotatably mounted at both ends of the support shaft 103. A torsion spring 105 is installed between the take-up roller 104 and the support shaft 103, and a rope 106 connects the take-up roller 104 and the bracket 501. As the support 501 moves away from the extruder 2 along with the wood-plastic composite board 4, the rope 106 drives the take-up roller 104 to rotate, and the torsion spring 105 undergoes elastic deformation to store energy. When the cut wood-plastic composite board 4 separates from the baffle 520, the torsion spring 105 converts the stored energy into the kinetic energy of the take-up roller 104. The take-up roller 104 reverses and drives the support 501 to move back to the side closer to the extruder 2 until the baffle 520 on the support 501 abuts against the free end face of the wood-plastic composite board 4 to be cut.

[0037] In some embodiments, please refer to Figure 3The workbench 1 is equipped with two conveyor rollers 107 for transporting the wood-plastic composite board 4. In this embodiment, two conveyor rollers 107 are rotatably mounted on the workbench 1, and the conveyor rollers 107 are parallel to the take-up roller 104. A space is formed between the two conveyor rollers 107 for the wood-plastic composite board 4 to pass through. The conveyor rollers 107 are located between the extruder 2 and the support 501, providing support for the wood-plastic composite board 4, thereby making the wood-plastic composite board 4 more stable during the transport process.

[0038] The above description is merely 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 within the protection scope of the present invention.
