Description

Technical Field

[0001] This utility model relates to the field of plastic product cutting technology, specifically a plastic product cutting device. Background Technology

[0002] Plastic products are a general term for daily necessities and industrial products made primarily from plastics. They include plastic films, plastic sheets, plastic pipes, etc. Plastic films refer to thin films made of polyvinyl chloride, polyethylene, polypropylene, polystyrene, and other resins, used for packaging or as a coating layer. After processing, plastic films are usually continuous and rolled up. In actual use, they need to be cut into appropriate lengths using a cutting device to meet different usage requirements.

[0003] Because plastic film has a certain degree of toughness, two sets of clamping mechanisms are usually designed on both sides of the cutting blade during cutting to clamp and fix the plastic film at the cutting position. After fixing, the tension of the film can be maintained, reducing the occurrence of uneven cut surfaces. This method can improve the accuracy of the cutting surface and reduce the occurrence of tearing.

[0004] However, in actual use, the plastic film is guided and transported by multiple sets of transmission rollers during the conveying process. During the friction between the plastic film and the transmission rollers, a large amount of static electricity is easily generated and accumulated. When the clamping mechanisms on both sides of the cutting blade approach or contact the plastic film, the static electricity will cause "electrostatic induction", which will cause the plastic film to be firmly attracted. After the cutting is completed, when the clamping mechanism moves away from the plastic film, the plastic film will be lifted up due to the adsorption force, causing misalignment and wrinkles. When the film that has been attracted falls down, it cannot return to its original precise position, which will cause deviations in subsequent cutting or processing. To address this problem, a plastic product cutting device is now provided. Utility Model Content

[0028] The principles and features of this utility model are described below with reference to the accompanying drawings. The examples given are only for explaining this utility model and are not intended to limit the scope of this utility model.

[0029] The present invention provides the following preferred embodiments:

[0030] Example 1, as Figures 1-5 As shown, a plastic product cutting device includes a processing table 11, and also includes a cutting mechanism, a pressing mechanism, a separating mechanism, a material transfer mechanism, and a feeding mechanism. The material transfer mechanism and the feeding mechanism are respectively installed at both ends of the processing table 11. The cutting mechanism is located between the material transfer mechanism and the feeding mechanism. The material transfer mechanism is used to move the tail end of the plastic film so that the position to be cut can be below the cutting blade 14. The feeding mechanism can cooperate with the material transfer mechanism to realize the unwinding of the plastic film.

[0031] The cutting mechanism includes a cutting blade 14, a lifting assembly, and two vertical plates 15. The two vertical plates 15 are symmetrically fixed on both sides of the top of the processing table 11. The cutting blade 14 is located in the middle of the two vertical plates 15, and the lifting assembly is located between the cutting blade 14 and the two vertical plates 15.

[0032] The lifting assembly is used to move the cutting blade 14. When the cutting blade 14 moves downward, it can cut the plastic film.

[0033] The clamping mechanism includes a drive assembly, a guide assembly, four moving rods 23 and four pressure blocks 24. The four pressure blocks 24 are symmetrically arranged on both sides of the two upright plates 15. Each pair of moving rods 23 is symmetrically arranged on the side of the two pressure blocks 24 that are far apart from each other. The guide assembly is located between the two upright plates 15 and the four moving rods 23. The drive assembly is located between the guide assembly and one of the upright plates 15.

[0034] The driving and guiding components enable the two pressure blocks 24 on both sides to move closer or further apart. When the two pressure blocks 24 on the same side move closer together, they can fix both sides of the plastic film to be cut, maintain the tension of the film, reduce the occurrence of uneven cut surfaces, improve cutting accuracy, and reduce the occurrence of tearing of the plastic film.

[0035] When the two pressure blocks 24 on the same side move away from each other, the clamping of the plastic film can be released;

[0036] It should be noted that the top surface of the cutting groove 13 is located between the two pressure blocks 24 on the same side;

[0037] The separation mechanism includes an air supply assembly and several air blowing ports 30. The air blowing ports 30 are respectively opened on the surface of the four pressure blocks 24. The air supply assembly is installed on one side of the processing table 11, and one end of the air supply assembly is connected to the several air blowing ports 30.

[0038] When the pressure block 24 is away from the plastic film after cutting, the air supply component can deliver gas to multiple air nozzles 30. Using several air nozzles 30, a small amount of compressed air is blown out at the moment the pressure block 24 is lifted, "blowing" the plastic film down, so that the plastic film is separated from the pressure block 24. This effectively reduces the adsorption phenomenon, so that the plastic film can return to its original precise position after cutting, avoiding being lifted by the adsorption force, causing misalignment and wrinkles, which is beneficial to improving the accuracy of subsequent cutting or processing.

[0039] like Figures 1-5 As shown, the guide assembly includes four side plates 20 and four slide rods 22. Every two side plates 20 are fixed to one side of a vertical plate 15. Each side plate 20 has two sliding grooves 21 on its surface. Every two slide rods 22 are located on one side of a vertical plate 15. Each slide rod 22 slides inside two of the sliding grooves 21, and both ends of each slide rod 22 are fixedly connected to one end of two moving rods 23 respectively.

[0040] By utilizing the sliding connection between the slide rod 22 and the slide groove 21, the conveying pipe 32 can be guided when it moves, so that the pressure block 24 can move in a certain direction and ensure the stability of the pressure block 24 when it moves.

[0041] like Figures 1-5As shown, the drive assembly includes a motor 25, a turntable 26, two hinge rods 27 and two connecting blocks 28. The motor 25 is fixed to one side of one of the upright plates 15, the turntable 26 is fixed to the output end of the motor 25, and the two connecting blocks 28 are respectively fixed to one side of two slide rods 22 above and below the motor 25. One end of each hinge rod 27 is hinged to a connecting block 28, and the other end of each hinge rod 27 is hinged to the surface edge of the turntable 26.

[0042] When it is necessary to move the pressure block 24, the controller controls the motor 25 to work. When the motor 25 works, it can drive the turntable 26 to rotate. Under the action of the two hinge rods 27, it can drive the two upper and lower slide rods 22 to slide inside the slide groove 21 through the connecting block 28. When the slide rods 22 slide, they can drive the upper and lower pressure blocks 24 to move closer or further apart through the moving rod 23, thereby achieving the positioning of the plastic film.

[0043] like Figures 1-5 As shown, the air supply assembly includes an air pump 29, a connecting pipe 34, a main pipe 35, four hoses 33, four delivery pipes 32, and several air blowing pipes 31. Each delivery pipe 32 is installed on the side of a moving rod 23 away from the pressure block 24. Several air blowing pipes 31 are respectively installed on the four delivery pipes 32. The other end of each air blowing pipe 31 is connected to one end of an air blowing port 30. The air pump 29 is fixed to one side of the processing table 11. The connecting pipe 34 is fixed to one side of one of the upright plates 15. One end of the main pipe 35 is connected to the output end of the air pump 29, and the other end of the main pipe 35 is connected to the connecting pipe 34. One end of each hose 33 is connected to one end of a delivery pipe 32, and the other end of each hose 33 is connected to the connecting pipe 34.

[0044] When the cutting is completed and the pressure block 24 is away from the plastic film, the controller controls the air pump 29 to work. The air pump 29 can deliver gas through the main pipe 35 to the connecting pipe 34. The hose 33 and the delivery pipe 32 can deliver the gas to multiple air blowing pipes 31. Then the gas can be sprayed out through multiple air blowing ports 30. A small amount of compressed air is blown out at the moment the pressure block 24 is lifted, which "blows" the plastic film down, so that the plastic film separates from the pressure block 24, effectively reducing the adsorption phenomenon.

[0045] like Figures 1-5 As shown, the lifting assembly includes a top plate 16, a cylinder 17, a cutter holder 19, and two guide rods 18. The top plate 16 is fixedly installed on the top of two vertical plates 15. The cutter holder 19 is located below the top plate 16. The cutting blade 14 is installed at the bottom of the cutter holder 19. The cylinder 17 is installed at the top of the top plate 16. The output end of the cylinder 17 passes through the top plate 16 and is fixedly connected to the cutter holder 19. The two guide rods 18 are symmetrically arranged on both sides of the cylinder 17. Each guide rod 18 is slidably arranged on the top plate 16. The bottom end of each guide rod 18 is fixedly connected to a cutter holder 19.

[0046] When it is necessary to cut the plastic film, the controller controls the cylinder 17 to work. The cylinder 17 can drive the cutter holder 19 to move up and down. When the cutter holder 19 moves, it can drive the cylinder 17 to move, thereby realizing the cutting of the plastic film. At the same time, when the cutter holder 19 moves, it can drive the guide rod 18 to slide on the top plate 16 to achieve the guiding function.

[0047] like Figures 1-5 As shown, the material transfer mechanism includes a movable frame 37, a movable plate 38, two electric slides 36 and multiple electric suction cups 39. The two electric slides 36 are symmetrically fixed on both sides of the processing table 11. The movable frame 37 is fixed on the two electric slides 36. The movable plate 38 is installed on one side of the movable frame 37. The multiple electric suction cups 39 are equidistantly installed at the bottom of the movable plate 38.

[0048] When it is necessary to move the plastic film, first move one end of the plastic film on the unwinding roller 40 to the top of the cutting table 12. Then, the electric slide 36 drives the moving frame 37 to move along the length of the processing table 11. The moving frame 37 drives multiple electric suction cups 39 to move through the moving plate 38. When the electric suction cups 39 move to the end of the plastic film, the multiple electric suction cups 39 can hold the end of the plastic film. Then, the electric slide 36 can drive the moving frame 37 to move in the opposite direction, thereby moving the plastic film and realizing the unwinding of the plastic film.

[0049] like Figures 1-5 As shown, the feeding mechanism includes an unwinding roller 40, a positioning shell 42, and multiple transmission rollers 41. Two first fixing plates 43 are symmetrically fixed on both sides of the top of the processing table 11. The unwinding roller 40 is rotatably disposed between the two first fixing plates 43. It should be noted that both ends of the unwinding roller 40 are fixed with rotating shafts, and each rotating shaft is rotatably connected to a first fixing plate 43 through a bearing. Multiple transmission rollers 41 are located on the side of the unwinding roller 40 close to the cutting blade 14. Each transmission roller 41 has a second fixing plate 44 rotatably disposed at both ends. The bottom end of each second fixing plate 44 is fixedly connected to the processing table 11. A positioning shell 42 is fixed on one side of one of the first fixing plates 43. A positioning mechanism is provided inside the positioning shell 42.

[0050] The plastic film can be guided by the transfer roller 41, and the positioning mechanism is used to position and fix the unwinding roller 40. When the moving frame 37 moves the plastic film to a suitable position, the positioning mechanism can fix the rotation axis of the unwinding roller 40 to prevent the unwinding roller 40 from continuing to rotate due to inertia, thereby ensuring the tension of the plastic film.

[0051] It should be noted that the positioning mechanism here mainly includes two positioning plates and two electric push rods. The two positioning plates are located on both sides of the rotating shaft, and each positioning plate is arc-shaped to match the rotating shaft. Each positioning plate has anti-slip stripes on the side near the rotating shaft to increase friction. Each electric push rod is installed on the inner wall of the positioning housing 42, and the output end of each electric push rod is connected to a positioning plate. When it is necessary to position the rotating shaft of the unwinding roller 40, the positioning plate is moved by the electric push rod, so that the positioning plate can clamp and fix the rotating shaft, thereby ensuring the stability of the unwinding roller 40. The positioning mechanism is existing technology and will not be described in detail here.

[0052] like Figures 1-5 As shown, a cutting table 12 is provided below the cutting blade 14. The cutting table 12 is fixed to the top of the processing table 11. A cutting groove 13 that cooperates with the cutting blade 14 is provided in the middle of the cutting table 12. The cutting groove 13 is designed to avoid direct contact between the cutting blade 14 and the cutting table 12, thus preventing the cutting blade 14 from wearing out.

[0053] The beneficial effects of this utility model are specifically reflected in the fact that the above description is only a preferred embodiment of this utility model and is not intended to limit this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
