Description

Technical Field

[0001] This utility model relates to the field of sheet processing equipment technology, specifically to a cutting device for ultra-high molecular weight polyethylene sheets. Background Technology

[0002] Ultra-high molecular weight polyethylene (UHMWPE) sheets are thermoplastic engineering plastics with extremely high molecular weights. They possess excellent properties such as wear resistance, self-lubrication, impact resistance, and corrosion resistance, and are widely used in various fields including chemical, food, and machinery. In practical applications, UHMWPE sheets need to be cut into different sizes to meet specific usage requirements.

[0003] Existing ultra-high molecular weight polyethylene (UHMWPE) sheet cutting equipment has significant shortcomings. In actual cutting operations, because the sheets often need to be cut multiple times, current equipment cannot achieve automatic feeding and still relies on manual labor to continuously move the sheets to the cutting position. This manual feeding method not only increases labor input and costs but also reduces work efficiency, making it difficult to meet the needs of large-scale, high-efficiency production and hindering practical applications.

[0004] Therefore, it is necessary to provide a cutting device for ultra-high molecular weight polyethylene sheets to solve the above-mentioned technical problems. Utility Model Content

[0005] The purpose of this invention is to provide a cutting device for ultra-high molecular weight polyethylene sheets to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A cutting device for ultra-high molecular weight polyethylene sheets, comprising:

[0008] The processing table has symmetrically distributed support legs fixedly installed on both sides of its bottom. The top of the processing table has an opening, and vertical rails are fixedly installed on both sides of the bottom of the processing table at the opening. Adjusting screws are rotatably installed inside the two vertical rails. Adjusting blocks are sleeved on the outer wall of the adjusting screws and are slidably connected to the vertical rails. A movable frame adapted to the opening is fixedly installed between the two adjusting blocks.

[0009] Both sides of the movable frame are rotatably mounted with transmission rollers, and a drive roller is rotatably mounted on the lower side of one side of the movable frame. A conveyor belt is provided between the two transmission rollers and the drive roller. A first servo motor is fixedly mounted on the lower side of the front side of the movable frame, and the drive end of the first servo motor passes through the movable frame and extends into the interior of the movable frame and is fixedly connected to the front end of the drive roller.

[0010] A drive mechanism is provided at the bottom of the vertical rail, and a cutting mechanism is provided on the top of the processing table on the side of the opening.

[0011] Preferably, a positioning frame is fixedly installed on the top of the processing table, a hydraulic telescopic rod is fixedly installed on the top of the positioning frame, and the driving end of the hydraulic telescopic rod passes through the positioning frame and extends to the top of the processing table. A pressure plate is fixedly installed on the driving end of the hydraulic telescopic rod.

[0012] Preferably, the cutting mechanism includes an electric track, which is fixedly installed on the top of the processing table on one side of the opening. A slider is slidably installed on the electric track, and a cutting motor is fixedly installed on one side of the slider. A cutting disc is fixedly installed on the drive end of the cutting motor.

[0013] Preferably, the driving mechanism includes a driving box, which is fixedly installed between the bottoms of two vertical rails. The bottom ends of the two adjusting screws pass through the vertical rails and the driving box in sequence and extend into the interior of the driving box. A worm gear is fixedly installed on the outer wall of the bottom end of the adjusting screw. A worm is rotatably installed inside the driving box and meshes with the worm gear. A second servo motor is fixedly installed on one side of the outer surface of the driving box, and the driving end of the second servo motor passes through the driving box and extends into the interior of the driving box, where it is fixedly connected to one end of the worm.

[0014] Preferably, the adjusting block has a threaded hole that matches the adjusting screw, and the adjusting block is threadedly connected to the adjusting screw through the threaded hole.

[0015] Preferably, the top of the processing table has a cutting groove corresponding to the position of the cutting disc.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] 1. This utility model, through the coordinated use of a processing table, electric track, slider, cutting disc, cutting groove, opening, conveyor belt, movable frame, first servo motor, vertical rail, worm gear, drive box, adjusting screw, worm wheel, second servo motor, transmission roller, drive roller, adjusting block, and cutting motor, enables automatic feeding of sheet metal. The transmission structure allows the conveyor belt to lift and transport the sheet metal, automatically completing the feeding and cutting cycle without frequent manual repositioning, thus reducing labor input and costs. Overall, it improves work efficiency, meets the needs of large-scale, high-efficiency production, and saves costs and increases profits for enterprises in the sheet metal processing process, creating greater value.

[0018] 2. This utility model utilizes a positioning frame, a pressure plate, and a hydraulic telescopic rod in conjunction. During the cutting of ultra-high molecular weight polyethylene (UHMWPE) sheets, the hydraulic telescopic rod can be activated, its drive end pushing the pressure plate vertically. This causes the pressure plate to move downwards until it is in close contact with the sheet surface, thus firmly securing the sheet at the top of the processing table. This operation effectively ensures the stability of the sheet during the cutting process, avoiding cutting errors caused by sheet shaking or displacement, thereby significantly improving cutting quality. When it is necessary to move the sheet for further processing or to complete the automatic feeding operation, the pressure plate is controlled to move upwards to reset. At this time, the pressure plate does not constrain the sheet, thus not interfering with the normal operation of the automatic sheet feeding function. Attached Figure Description

[0028] Please see Figures 1-4 One embodiment provided by this utility model:

[0029] A cutting device for ultra-high molecular weight polyethylene sheets, comprising:

[0030] The processing table 1 has symmetrically distributed support legs 2 fixedly installed on both sides of its bottom. The top of the processing table 1 has an opening 10.

[0032] A drive mechanism is provided at the bottom of the vertical rail 14, and a cutting mechanism is provided on the top of the processing table 1 on one side of the opening 10.

[0033] A positioning frame 7 is fixedly installed on the top of the processing table 1. A hydraulic telescopic rod 9 is fixedly installed on the top of the positioning frame 7. The driving end of the hydraulic telescopic rod 9 passes through the positioning frame 7 and extends to the top of the processing table 1. A pressure plate 8 is fixedly installed on the driving end of the hydraulic telescopic rod 9, which realizes the limiting effect on the board and ensures the cutting quality of the board.

[0034] In one embodiment, the cutting mechanism includes an electric track 3, which is fixedly installed on the top of the processing table 1 on one side of the opening 10. A slider 4 is slidably installed on the electric track 3, and a cutting motor 23 is fixedly installed on one side of the slider 4. A cutting disc 5 is fixedly installed on the drive end of the cutting motor 23, thereby achieving the cutting effect on the board.

[0035] In one preferred embodiment, the drive mechanism includes a drive box 16, which is fixedly installed between the bottoms of two vertical rails 14. The bottom ends of two adjusting screws 17 pass through the vertical rails 14 and the drive box 16 in sequence and extend into the interior of the drive box 16. A worm gear 18 is fixedly installed on the outer wall of the bottom end of the adjusting screw 17. A worm 15 is rotatably installed inside the drive box 16 and meshes with the worm gear 18. A second servo motor 19 is fixedly installed on one side of the outer surface of the drive box 16, and the drive end of the second servo motor 19 passes through the drive box 16 and extends into the interior of the drive box 16 and is fixedly connected to one end of the worm 15, thereby realizing the automatic lifting function of the conveyor belt 11.

[0036] In one embodiment, the adjusting block 22 has a threaded hole that matches the adjusting screw 17, and the adjusting block 22 is threadedly connected to the adjusting screw 17 through the threaded hole, which can convert the rotation of the adjusting screw 17 into linear movement of the adjusting block 22, thereby realizing precise vertical displacement of the movable frame 12 and the conveyor belt 11 and ensuring stable and accurate feeding of the plate.

[0037] In one preferred embodiment, the top of the processing table 1 is provided with a cutting groove 6 corresponding to the position of the cutting disc 5, which can prevent the cutting disc 5 from damaging the processing table 1 during cutting, ensure smooth cutting, improve cutting quality, and extend the service life of the equipment.

[0038] The working principle of this utility model is as follows: All electrical components mentioned are electrically connected to the main controller and power supply. The main controller can be a computer or other conventionally known control device, and existing publicly available power connection technologies are not elaborated here. Parts not mentioned in this device are the same as or can be implemented using existing technologies. In use, the ultra-high molecular weight polyethylene sheet is placed on top of the processing table 1, and the second servo motor 19 is started. Its drive end drives the worm gear 15 to rotate. Through the meshing transmission between the worm gear 15 and the worm wheel 18, the two worm wheels 18 rotate synchronously, thereby driving the adjusting screw 17 to rotate. Through the threaded transmission between the adjusting screw 17 and the adjusting block 22, and the sliding of the adjusting block 22 along the vertical rail 14, the two adjusting blocks 22 move vertically synchronously, driving the movable frame 12 to move. The movable frame 12 drives the conveyor belt 11 to move via the transmission roller 20, causing the conveyor belt 11 to rise through the opening 10 and slightly lift the sheet. Then, the first servo motor 13 is activated, which drives the drive roller 21 to rotate. This, in conjunction with the two transmission rollers 20, causes the conveyor belt 11 to rotate and transport the sheet material to below the electric track 3, aligning the cutting position with the cutting disc 5. After loading, the conveyor belt 11 moves down to be flush with the top of the processing table 1, ensuring contact between the sheet material and the table surface. The slider 4 and the cutting motor 23 are then activated. The cutting motor 23 drives the cutting disc 5 to rotate, and the slider 4 slides on the electric track 3, causing the cutting disc 5 to move longitudinally. The rotating cutting disc 5 contacts the sheet material to complete the cutting. After cutting, the conveyor belt 11 moves up again to lift the sheet material and continue loading and cutting until the entire sheet material is cut. This device achieves automatic sheet material loading, eliminating the need for frequent manual repositioning, reducing labor and costs, improving efficiency, meeting the needs of large-scale, high-efficiency production, and demonstrating high practicality.

[0039] During the cutting of ultra-high molecular weight polyethylene (UHMWPE) sheets, the hydraulic telescopic rod 9 can be activated. Its drive end pushes the pressure plate 8 to move vertically, causing the pressure plate 8 to move downward until it is in close contact with the sheet surface, thereby firmly limiting the sheet to the top of the processing table 1. This operation effectively ensures the stability of the sheet during the cutting process, avoiding cutting errors caused by sheet shaking or displacement, and thus significantly improving cutting quality. When it is necessary to move the sheet for further processing or to complete the automatic feeding operation, the pressure plate 8 is controlled to move upward to reset. At this time, the pressure plate 8 does not constrain the sheet, thus not interfering with the normal operation of the automatic sheet feeding function.

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