Description

Technical Field

[0001] This invention relates to the field of edge trimming of rubber and plastic foam materials, and particularly to an edge trimming equipment and processing technology for rubber and plastic foam materials. Background Technology

[0002] Rubber and plastic foam materials are a type of lightweight, porous polymer material made through a foaming process. Due to their excellent cushioning, shock absorption, heat insulation, sound insulation, softness and resilience, and sealing and waterproofing properties, they are widely used in footwear, sporting goods, automotive interiors, building sealing, packaging protection and other fields. Rubber and plastic foam materials are usually first made into large blocks of "raw materials" through large-scale molding or continuous foaming production lines. These raw materials are semi-finished products and must go through a cutting process to obtain the specific shape and size required for the final product. Cutting is a key step in realizing the transformation of products from "materials" to "parts".

[0003] Chinese patent with publication number "CN120055510A" discloses "a cutting and processing equipment for rubber and plastic foam materials and its processing technology, which relates to the field of laser cutting technology for rubber and plastic foam materials. The equipment includes a base plate, a first linear motor fixedly mounted on the upper surface of the base plate, a worktable fixedly connected to the output end of the first linear motor, a support frame fixedly mounted on the upper surface of the base plate, an mounting frame fixedly connected to the upper surface of the support frame, an adjustment mechanism fixedly mounted on the outer wall of the mounting frame, a second cylinder fixedly connected to the output end of the adjustment mechanism, a lower fixing block provided at the output end of the second cylinder, and a lower pressing mechanism fixedly mounted at the output end of the adjustment mechanism".

[0004] Although the laser beam in the aforementioned patent does not act directly on the worktable and will not damage the worktable surface, and the residue from the molten carbonization of the cut edge of the rubber and plastic foam material will not drip onto the worktable, the lack of an effective real-time smoke exhaust and heat dissipation structure means that high-temperature smoke and dust can easily accumulate near the cutting area, which not only affects the cutting accuracy and service life of the laser head, but may also contaminate the surface of the processed material. Summary of the Invention

[0005] The main objective of this invention is to provide a cutting and processing equipment for rubber and plastic foam materials, which can effectively solve the technical problems in the background art.

[0006] To achieve the above objectives, the technical solution adopted by the present invention is as follows:

[0011] As a further embodiment of the present invention, a power shaft is fixedly connected to the adjacent sides of the two fan blades, and a support shaft is fixedly connected to the distant sides of the two fan blades. The support shaft is rotatably connected to the grid frame. The power shaft is rotatably connected to one side of the fixed frame and the inside of the docking frame. Four long shaft bolts are threaded between the fixed frame and the docking frame. The fan blade on one side is arranged in a forward-facing configuration, and the fan blade on the other side is arranged in a reverse-facing configuration.

[0012] As a further embodiment of the present invention, a second motor is fixedly connected to the top of the docking frame, and a first bevel gear is fixedly connected to the near ends of the two power shafts. A vertical shaft is rotatably connected inside the docking frame in a vertical state. The output shaft of the second motor is fixedly connected to the vertical shaft, and a second bevel gear is fixedly connected to the bottom end of the vertical shaft. The second bevel gear meshes with two first bevel gears.

[0013] As a further embodiment of the present invention, a base is provided between the two bases, a vacuum clamp is fixedly connected to the top of the base, two connecting pipes are fixedly connected to the front of the vacuum clamp, a pressure gauge is provided at the close end of the two connecting pipes, and flanges are connected to both sides of the pressure gauge and the two connecting pipes.

[0014] As a further embodiment of the present invention, the bottom of the baffle is provided with an anti-tilting structure, which includes four base plates. A base block is fixedly connected to each of the four corners of the bottom of the baffle. A rotating shaft is fixedly connected to both sides of each base plate. The rotating shaft is rotatably connected to the inside of the base block. A connecting shaft is fixedly connected to one end of the rotating shaft on one side of the base plate and inside the base block. A fixing box is fixedly connected to the sides of each of the four base blocks. A coil spring is provided inside each fixing box.

[0015] As a further embodiment of the present invention, one end of the disc spring is fixedly connected to the inner wall of the fixed box, the other end of the disc spring is fixedly connected to the outer surface of the connecting shaft, and the connecting shaft is rotatably connected to the bottom block.

[0016] As a further embodiment of the present invention, each of the base plates is symmetrically and fixedly connected to two support blocks on the left and right sides, and a rotating rod is rotatably connected between the two support blocks. An infrared sensor is fixedly connected to one side of the lifting frame, and the bottom of the inner cover is at a higher height than the bottom of the baffle.

[0017] A process for edge trimming of rubber and plastic foam material, the method specifically includes the following steps: Step 1: Place the rubber and plastic foam board to be cut on the base, then start motor 1, and drive two lead screws to rotate synchronously through two pulleys and belts, thereby driving two columns and crossbeams and connected components to move synchronously back and forth through two sliders, then start the electric slide rail to drive the moving frame to move left and right, and finally start the cylinder and laser cutting head, so that the rubber and plastic foam board can be laser-cut by the laser cutting head;

[0018] Step 2: During laser cutting, the two fan blades rotate synchronously. Since the fan blades on one side are set with the blades facing forward and the fan blades on the other side are set with the blades facing backward, the airflow direction of the fan blades on one side is from right to left, and the airflow direction of the fan blades on the other side is from left to right. The air is blown into the inner cover through the air blowing pipe, thereby blowing the heat and smoke generated by the laser cutting head to the inside of the air intake jacket. The air intake pipe absorbs the heat and smoke inside the air intake jacket, thereby preventing heat from continuously accumulating at the laser cutting head position.

[0019] As shown in the attached diagram, the air blowing pipe and the air suction pipe are bent. Therefore, as the laser cutting head moves up and down, the air blowing pipe and the air suction pipe have extra length to move, thereby avoiding breakage of the air blowing pipe and the air suction pipe.

[0020] Because the adjacent sides of the two fixed frames are blocked by the two sides of the docking frame, the generated gas can only be transmitted through the suction pipe and the blowing pipe.

[0021] Step 3: Start motor 2, which drives the vertical shaft to rotate, thereby driving bevel gear 2 to rotate synchronously, which in turn drives the two bevel gears 1 to rotate synchronously. Therefore, the two fan blades are driven to rotate synchronously through the two power shafts, thus starting the blowing and suction structure.

[0022] Place the rubber and plastic foam board to be cut on top of the vacuum clamp, and then start the vacuum clamp to fix the rubber and plastic foam board in place and prevent it from shaking during cutting.

[0023] Step 4: When the laser cutting head moves down, it will drive the baffle to move down synchronously, thereby driving the four base plates to move down synchronously until they are pressed against the rubber and plastic foam board. They move together with the laser cutting head as it moves forward, backward, left, and right. When it moves forward and backward, the two base plates located at the front and back will rotate together until the coil spring is in its maximum contraction state. When it moves left and right, the movement of the two base plates located on the sides is the same as above. Through the contraction and rebound force of the coil spring, the cutting part of the rubber and plastic foam board is moved down a second time to prevent the cutting part of the rubber and plastic foam board from warping.

[0024] The beneficial effects of this invention are as follows:

[0025] By setting up a blow-suction structure in conjunction with a baffle, real-time processing of smoke and heat can be achieved during laser cutting. This effectively captures and removes harmful fumes and high-temperature gases generated during processing, preventing their accumulation in the cutting area. This ensures a uniform and clean cutting surface, extends the lifespan of the laser head, and maintains visibility and safety in the working environment.

[0026] By setting up flexible air blowing and suction pipes, these pipes have good deformation recovery ability and motion adaptability. They can bend and stretch freely when the cutting head moves in a three-dimensional complex trajectory, avoiding fatigue fracture or loosening of the interface caused by mechanical pulling, and significantly improving the reliability and long-term durability of the system.

[0027] By setting up an anti-warping structure and a multi-directional adjustable base plate, adjustable flexible pressure is applied to the edge of the rubber and plastic foam board during the laser cutting process. The pressing force can be adaptively adjusted according to the material thickness and cutting speed, effectively suppressing the warping phenomenon caused by thermal stress or material deformation, ensuring that the material remains flat during the cutting process, with high cutting precision and no burrs.

[0028] By replacing the traditional sliding contact structure with a rotating friction component, a freely rolling rotating rod device is introduced at the bottom of the anti-warping pressing device, which changes the sliding friction to rolling friction when in contact with the material surface. This greatly reduces the coefficient of friction, avoids scratching the material surface during the pressing process, and takes into account both the anti-warping stability and surface protection functions. It is especially suitable for soft and easily scratched foamed materials.

[0029] Under the simultaneous action of blowing and suction, an air vortex is generated at the bottom of the suction jacket, thus forming a stable local airflow barrier around the laser cutting head. This vortex can effectively constrain and guide the smoke and splashes generated during cutting toward the suction jacket, preventing pollutants from spreading outward and improving smoke extraction efficiency. This not only enhances the airflow control precision in the processing area but also further reduces the adhesion of smoke to the laser cutting head and material surface, helping to maintain the cleanliness of the cutting process and the stability of long-term operation.

Detailed Implementation

[0042] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0043] like Figure 1 - Figure 11 As shown, a rubber and plastic foam material edge cutting processing equipment includes two bases 2, each with a base frame 4 on top, and each base frame 4 with a column 5 fixedly connected to the top of the two base frames 4. A crossbeam 6 is fixedly connected between the two columns 5. An electric slide rail 12 is fixedly connected to the front of the crossbeam 6. A movable frame 7 is slidably connected to the top of the crossbeam 6 via the electric slide rail 12. A lifting rail 18 is fixedly connected to the front of the movable frame 7. A lifting frame 15 is slidably connected to the front of the movable frame 7 via the lifting rail 18. Two fixing blocks 16 are fixedly connected to the front of the lifting frame 15. A laser cutting head 17 is connected to the two fixing blocks 16. A blowing and suction structure 8 is provided on the top of the movable frame 7.

[0044] The blowing and suction structure 8 includes an air blowing pipe 26 and an air suction pipe 27. Connecting blocks 24 are fixedly connected to both sides of the bottom fixing block 16. A baffle 25 is fixedly connected to the bottom of the bottom fixing block 16 through two connecting blocks 24. A docking frame 22 is fixedly connected to the top of the movable frame 7 on one side. Fixing frames 21 are provided on both sides of the docking frame 22. A mesh frame 23 is fixedly connected to the far sides of the two fixing frames 21. Fan blades 30 are provided inside the two fixing frames 21. An inner cover 28 is fixedly connected inside the baffle 25. An air suction interlayer 29 is provided between the outer surface of the inner cover 28 and the inside of the baffle 25. The air suction pipe 27 is fixedly connected between the baffle 25 and the fixing frame 21 on one side. The air blowing pipe 26 is fixedly connected between the inner cover 28 and the fixing frame 21 on the other side.

[0045] In actual operation, the rubber and plastic foam board to be cut is placed on the base 1, and then the motor 9 is started. The two pulleys 19 and belt 20 drive the two lead screws 11 to rotate synchronously. This drives the two columns 5 and the crossbeam 6 and the connected parts to move back and forth synchronously through the two sliders 10. Then the electric slide rail 12 is started, which drives the moving frame 7 to move left and right. Finally, the cylinder 13 and the laser cutting head 17 are started, so that the rubber and plastic foam board can be laser cut through the laser cutting head 17.

[0046] During laser cutting, two fan blades 30 rotate synchronously. Since the fan blade 30 on one side is set with a forward blade and the fan blade 30 on the other side is set with a reverse blade, the airflow direction of the fan blade 30 on one side is from right to left, and the airflow direction of the fan blade 30 on the other side is from left to right. The air is blown into the inner cover 28 through the air blowing pipe 26, thereby blowing the heat and smoke generated by the laser cutting head 17 to the inside of the air intake jacket 29. The air intake pipe 27 absorbs the heat and smoke inside the air intake jacket 29, thereby preventing the heat from continuously accumulating at the laser cutting head 17.

[0047] As shown in the attached diagram, the air blowing pipe 26 and the air suction pipe 27 are bent. Therefore, as the laser cutting head 17 moves up and down, the air blowing pipe 26 and the air suction pipe 27 have extra length to move, thereby preventing the air blowing pipe 26 and the air suction pipe 27 from breaking.

[0048] In this embodiment, both bases 2 are rotatably connected to lead screws 11 inside, and sliders 10 are slidably connected to lead screws 11 inside bases 2. Both sides of the bases 2 are provided with through slots 3. The sliders 10 pass through the two through slots 3 and are fixedly connected to the base frame 4. A motor 9 is fixedly connected to the front of one side of the base 2. The output shaft of the motor 9 passes through the interior of the base 2 and is fixedly connected to lead screws 11. Both bases 2 are rotatably connected to pulleys 19 at the rear. A belt 20 is sleeved between the two pulleys 19. The two lead screws 11 are fixedly connected to the two pulleys 19 respectively.

[0049] In this embodiment, an energy storage tank 14 is fixedly connected to the top of the mobile frame 7 on the other side. A connecting pipe is connected between the energy storage tank 14 and the laser cutting head 17. A cylinder 13 is fixedly connected to the front of the top of the mobile frame 7. The output shaft of the cylinder 13 is fixedly connected to the lifting frame 15. As can be seen from the attached drawings, the connecting pipe is also bent to accommodate the up and down movement of the laser cutting head 17.

[0050] In this embodiment, a power shaft 32 is fixedly connected to the adjacent sides of the two fan blades 30, and a support shaft 33 is fixedly connected to the distant sides of the two fan blades 30. The support shaft 33 is rotatably connected to the grid frame 23. The power shaft 32 is rotatably connected to one side of the fixed frame 21 and the inside of the docking frame 22. Four long shaft bolts 31 are threaded between the fixed frame 21 and the docking frame 22. The fan blade 30 on one side is arranged in a forward-facing configuration, and the fan blade 30 on the other side is arranged in a reverse-facing configuration.

[0051] Since the adjacent sides of the two fixed frames 21 are blocked by the two sides of the docking frame 22, the generated gas can only be transmitted through the suction pipe 27 and the blowing pipe 26.

[0052] In this embodiment, a second motor 41 is fixedly connected to the top of the docking frame 22, and a first bevel gear 38 is fixedly connected to the near ends of the two power shafts 32. A vertical shaft 40 is rotatably connected inside the docking frame 22 in a vertical state. The output shaft of the second motor 41 is fixedly connected to the vertical shaft 40, and a second bevel gear 39 is fixedly connected to the bottom end of the vertical shaft 40. The second bevel gear 39 meshes with the two first bevel gears 38.

[0053] The motor 41 is started, which drives the vertical shaft 40 to rotate, thereby driving the bevel gear 39 to rotate synchronously, which in turn drives the two bevel gears 38 to rotate synchronously. Therefore, the two fan blades 30 are driven to rotate synchronously through the two power shafts 32, thereby starting the blowing and suction structure 8.

[0054] In this embodiment, a base 1 is provided between two bases 2. A vacuum clamp 34 is fixedly connected to the top of the base 1. Two connecting pipes 36 are fixedly connected to the front of the vacuum clamp 34. A pressure gauge 35 is provided at the close end of the two connecting pipes 36. Flanges 37 are connected between the two sides of the pressure gauge 35 and the two connecting pipes 36.

[0055] Place the rubber and plastic foam board to be cut on top of the vacuum clamp 34, and then start the vacuum clamp 34 to fix the rubber and plastic foam board and prevent it from shaking during cutting.

[0056] In this embodiment, the bottom of the cover 25 is provided with an anti-tilting structure 42, which includes four base plates 43. The bottom of the cover 25 is fixedly connected to the four corners of each base plate 43. The two sides of each base plate 43 are fixedly connected to a rotating shaft 46, which is rotatably connected to the inside of the base plate 44. One end of the rotating shaft 46 on the side of the base plate 43 and inside the base plate 44 is fixedly connected to a connecting shaft 47. The sides of the four base plates 44 are fixedly connected to a fixing box 45, and the inside of the fixing box 45 is provided with a coil spring 48.

[0057] When the laser cutting head 17 moves downward, it will drive the baffle 25 to move downward synchronously, thereby driving the four base plates 43 to move downward synchronously until they are pressed against the rubber and plastic foam board. They move together with the laser cutting head 17 as it moves forward, backward, left, and right. When it moves forward and backward, the two base plates 43 located at the front and rear will rotate together until the coil spring 48 is in the maximum contraction state. When it moves left and right, the movement of the two base plates 43 located on both sides is the same as above. Through the contraction and rebound force of the coil spring 48, the cutting part of the rubber and plastic foam board is moved downward a second time to avoid the cutting part of the rubber and plastic foam board from warping.

[0058] In this embodiment, one end of the coil spring 48 is fixedly connected to the inner wall of the fixed box 45, and the other end of the coil spring 48 is fixedly connected to the outer surface of the connecting shaft 47. The connecting shaft 47 is rotatably connected to the bottom block 44.

[0059] In this embodiment, each base plate 43 has two support blocks 49 fixedly connected symmetrically to its bottom. A rotating rod 50 is rotatably connected between the two support blocks 49. When the base plate 43 moves down, it will drive the rotating rod 50 to move down as well. The rotating rod 50 will first squeeze the rubber and plastic foam board. Through the rotatable setting of the rotating rod 50, the friction between the base plate 43 and the rubber and plastic foam board can be converted from sliding friction to rotational friction, thereby reducing the friction between the two and avoiding scratching the top of the rubber and plastic foam board due to sliding friction.

[0060] In this embodiment, an infrared sensor 51 is fixedly connected to one side of the lifting frame 15. The bottom of the inner cover 28 is at a higher height than the bottom of the baffle 25. The infrared sensor 51 is model "GP2Y0A21". The infrared sensor 51 assists the laser cutting head 17 in positioning. Since the bottom of the inner cover 28 is higher than the bottom of the baffle 25, the bottom of the suction jacket 29 will generate an air vortex under the synchronous action of blowing and suction, thereby forming a stable local airflow barrier around the laser cutting head. This vortex can effectively constrain and guide the smoke and splashes generated during cutting towards the suction jacket, preventing pollutants from spreading outward and improving the smoke extraction efficiency. This not only enhances the airflow control accuracy of the processing area, but also further reduces the adhesion of smoke to the laser cutting head 17 and the material surface, which helps to maintain the cleanliness of the cutting process and the stability of long-term operation.

[0061] It should be noted that the present invention is a rubber and plastic foam material edge cutting processing equipment. In use, the rubber and plastic foam board to be cut is placed on the base 1, and then the motor 9 is started, which drives the two lead screws 11 to rotate synchronously through the two pulleys 19 and the belt 20. This drives the two columns 5 and the crossbeam 6 and the connected parts to move back and forth synchronously through the two sliders 10. Then the electric slide rail 12 is started, which drives the moving frame 7 to move left and right. Finally, the cylinder 13 and the laser cutting head 17 are started, so that the rubber and plastic foam board can be laser cut through the laser cutting head 17.

[0062] During laser cutting, two fan blades 30 rotate synchronously. Since the fan blade 30 on one side is set with a forward blade and the fan blade 30 on the other side is set with a reverse blade, the airflow direction of the fan blade 30 on one side is from right to left, and the airflow direction of the fan blade 30 on the other side is from left to right. The air is blown into the inner cover 28 through the air blowing pipe 26, thereby blowing the heat and smoke generated by the laser cutting head 17 to the inside of the air intake jacket 29. The air intake pipe 27 absorbs the heat and smoke inside the air intake jacket 29, thereby preventing the heat from continuously accumulating at the laser cutting head 17.

[0063] As shown in the attached diagram, the air blowing pipe 26 and the air suction pipe 27 are bent. Therefore, as the laser cutting head 17 moves up and down, the air blowing pipe 26 and the air suction pipe 27 have extra length to move, thereby preventing the air blowing pipe 26 and the air suction pipe 27 from breaking.

[0064] Since the adjacent sides of the two fixed frames 21 are blocked by the two sides of the docking frame 22, the generated gas can only be transmitted through the suction pipe 27 and the blowing pipe 26.

[0065] The motor 41 is started, which drives the vertical shaft 40 to rotate, thereby driving the bevel gear 39 to rotate synchronously, which in turn drives the two bevel gears 38 to rotate synchronously. Therefore, the two fan blades 30 are driven to rotate synchronously through the two power shafts 32, thereby starting the blowing and suction structure 8.

[0066] Place the rubber and plastic foam board to be cut on top of the vacuum clamp 34, and then start the vacuum clamp 34 to fix the rubber and plastic foam board and prevent it from shaking during cutting.

[0067] When the laser cutting head 17 moves downward, it will drive the baffle 25 to move downward synchronously, thereby driving the four base plates 43 to move downward synchronously until they are pressed against the rubber and plastic foam board. They move together with the laser cutting head 17 as it moves forward, backward, left, and right. When it moves forward and backward, the two base plates 43 located at the front and rear will rotate together until the coil spring 48 is in the maximum contraction state. When it moves left and right, the movement of the two base plates 43 located on both sides is the same as above. Through the contraction and rebound force of the coil spring 48, the cutting part of the rubber and plastic foam board is moved downward a second time to avoid the cutting part of the rubber and plastic foam board from warping.

[0068] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the invention. Various changes and modifications can be made to the invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed invention.

10. A process for edge trimming of rubber and plastic foam materials according to any one of claims 1-9, characterized in that: The method specifically includes the following steps: Step 1: Place the rubber and plastic foam board to be cut on the base 1, then start the motor (9), and drive the two lead screws (11) to rotate synchronously through the two pulleys (19) and belt (20), thereby driving the two columns (5) and crossbeam (6) and the connected parts to move back and forth synchronously through the two sliders (10). Then start the electric slide rail (12) to drive the moving frame (7) to move left and right. Finally, start the cylinder (13) and laser cutting head (17) so that the rubber and plastic foam board can be laser cut through the laser cutting head (17). Step 2: During laser cutting, the two fan blades (30) are rotated synchronously. Since the fan blade (30) on one side is set as a positive blade and the fan blade (30) on the other side is set as a negative blade, the airflow direction of the fan blade (30) on one side is from right to left, and the airflow direction of the fan blade (30) on the other side is from left to right. The air is blown into the inner cover (28) through the air blowing pipe (26), thereby blowing the heat and smoke generated by the laser cutting head (17) during cutting into the air intake jacket (29). The air intake pipe (27) absorbs the heat and smoke inside the air intake jacket (29), thereby preventing the heat from continuously accumulating at the laser cutting head (17). As can be seen from the attached figure, the blowing pipe (26) and the suction pipe (27) are bent. Therefore, as the laser cutting head (17) moves up and down, its blowing pipe (26) and suction pipe (27) have extra length to move, thereby avoiding the breaking of the blowing pipe (26) and suction pipe (27). Since the adjacent sides of the two fixed frames (21) are blocked by the two sides of the docking frame (22), the generated gas can only be transmitted through the suction pipe (27) and the blowing pipe (26); Step 3: Start motor 2 (41), drive the vertical shaft (40) to rotate, thereby drive bevel gear 2 (39) to rotate synchronously, and then drive two bevel gears 1 (38) to rotate synchronously. Therefore, through the two power shafts (32), drive the two fan blades (30) to rotate synchronously, thereby starting the blowing and suction structure (8); Place the rubber and plastic foam board to be cut on top of the vacuum clamp (34), and then start the vacuum clamp (34) to fix the rubber and plastic foam board and prevent it from shaking during cutting. Step 4: When the laser cutting head (17) moves down, it will drive the baffle (25) to move down synchronously, thereby driving the four base plates (43) to move down synchronously until they are squeezed against the rubber and plastic foam board. They move together with the laser cutting head (17) moving back and forth and left and right. When moving back and forth, the two base plates (43) located at the front and back will rotate together until the coil spring (48) is in the maximum contraction state. When moving left and right, the movement of the two base plates (43) located on both sides is the same as above. Through the contraction and rebound force of the coil spring (48), the cutting part of the rubber and plastic foam board is moved down a second time to avoid the cutting part of the rubber and plastic foam board from warping.
