Detailed Implementation
[0023] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.
[0024] like Figures 1 to 5As shown in the embodiment of this utility model, a polyethylene profile cutting device includes a support plate 1; a support leg 2 is fixedly connected to the bottom end of the support plate 1; a flat plate 3 is slidably connected to the top end of the support plate 1; a pair of vertical plates 4 are fixedly connected to the top end of the support plate 1; the flat plate 3 is slidably connected to the opposite side of the pair of vertical plates 4; a cross plate 5 is fixedly connected to the top end of the pair of vertical plates 4; a cutting blade 6 is provided at the bottom end of the cross plate 5; a cylinder telescopic rod 7 is fixedly connected to the top end of the cross plate 5; a connecting plate 8 is fixedly connected to the telescopic end of the cylinder telescopic rod 7; and the cutting blade 6 is fixedly connected to the bottom of the connecting plate 8. The top of the plate 3 is equipped with a cleaning component. The cleaning component is used to clean the cutting blade 6. During operation, the support plate 1 and the support leg 2 can support the support plate 1. A pair of vertical plates 4 fixed to the top of the support plate 1 can support the cross plate 5 and the cutting blade 6. After the cutting blade 6 cuts the material plate once, the cleaning component at the top of the plate 3 can clean the cutting blade 6 as it moves downward, removing the debris and impurities adhering to the cutting blade 6 and preventing the cutting blade 6 from deviating in size during the next cut.
[0025] The cleaning component includes a first placement plate 9; a pair of first placement plates 9 are fixedly connected to the top of a flat plate 3; a pair of second placement plates 10 are fixedly connected to the top of the flat plate 3; a first groove 11 is formed on one side of each pair of first placement plates 9; a rotating roller 12 is rotatably connected to each pair of first grooves 11; a belt 13 is sleeved on each pair of rotating rollers 12; a U-shaped plate 14 is fixedly connected to one side of each pair of belts 13; a set of cleaning brushes 15 is fixedly connected to one side of each pair of U-shaped plates 14; a first motor 16 is fixedly connected to one side of each pair of first placement plates 9; a first rotating shaft 17 is fixedly connected inside each pair of rotating rollers 12; a pair of first rotating... One of the moving shafts 17 has one end passing through the first placement plate 9 and is located at the output end of the first motor 16. During operation, by setting a pair of first placement plates 9 and a pair of second placement plates 10 on the top of the flat plate 3, the operator places the material board on the first placement plate 9 and the second placement plate 10. The cylinder telescopic rod 7 will drive the cutter 6 to move downward and cut the material board. The pair of first motors 16 will continuously drive a pair of cleaning brushes 15 to rotate in the first groove 11. When the cutter 6 enters between the pair of first placement plates 9, the continuously rotating cleaning brushes 15 can clean both sides of the cutter 6 after the cutter 6 enters, thus completing the cleaning work of the cutter 6.
[0026] The top of the plate 3 has a pair of second grooves 20; a first toothed plate 21 is slidably connected to the inner sidewall of each pair of second grooves 20; each pair of first toothed plates 21 penetrates the plate 3; a clamping plate 22 is fixedly connected to each pair of first toothed plates 21; a power component is provided in the second groove 20; the power component is used to drive the movement of the first toothed plate 21. During operation, by opening the second groove 20 at the top of the plate 3 and setting the power component in the second groove 20, when the power component drives the first toothed plate 21 to move downward, the clamping plate 22 will gradually contact the material plate and clamp and fix the material plate, ensuring that the material plate will not move during the cutting process.
[0027] The power component includes a second motor 23; the second motor 23 is fixedly connected inside the second groove 20; the output end of the second motor 23 is provided with a first rotating rod 24; one end of the first rotating rod 24 passes through a pair of second placement plates 10; a pair of gears 19 are fixedly connected to the first rotating rod 24; the first toothed plate 21 meshes with the gears 19. During operation, by setting the second motor 23 inside the second groove 20, when the operator starts the second motor 23, the first rotating rod 24 will drive the pair of gears 19 to mesh with the pair of first toothed plates 21 inside the second groove 20 respectively, causing the pair of first toothed plates 21 to move downward. When the clamping plate 22 contacts the material plate, it clamps and fixes the material plate.
[0028] A pair of second toothed plates 28 are slidably connected to the inner sidewalls of the second grooves 20, and the second toothed plates 28 penetrate the flat plate 3; a pair of through slots 29 are provided at the top of the support plate 1; the pair of second toothed plates 28 are slidably connected in the through slots 29; a T-shaped slot 30 is provided in each of the pair of through slots 29; a T-shaped block 31 is fixedly connected to one side of each pair of second toothed plates 28; the pair of T-shaped blocks 31 are slidably connected in the T-shaped slots 30; the second toothed plates 28 mesh with the gear 19. During operation, by setting the second toothed plates 28 slidably connected to the inner sidewalls of the second grooves 20, when the gear 19 meshes with the second toothed plates 28, the second toothed plates 28 will engage with the gear 19. The toothed plate 28 moves downwards or upwards because the plate 3 can slide on the support plate 1. When the worker pushes the plate 3 back into the equipment, the second motor 23 can drive the second toothed plate 28 upwards, so that the T-shaped block 31 enters the T-shaped slot 30, restricting the plate 3 and preventing it from moving. This prevents the plate 3 from moving during the material cutting process and causing problems with the material cutting. After the cutting is completed, the power component reverses, causing the T-shaped block 31 to move out of the T-shaped slot 30, restoring the plate 3 to its moving function. The worker can then pull the plate 3 outwards to easily remove the cut plate from the plate 3.
[0029] The clamping surface of the clamping plate 22 is provided with an anti-slip pad. During operation, the friction between the clamping plate 22 and the object being clamped can be increased by providing an anti-slip pad on the clamping plate 22, thereby enhancing the stability of the clamping.
[0030] Working principle: By setting up support plate 1, support legs 2 can support support plate 1. A pair of vertical plates 4 fixed to the top of support plate 1 can support cross plate 5 and cutting blade 6. After the cutting blade 6 cuts the material board once, the cleaning device set at the top of the plate 3 can clean the cutting blade 6 as it moves downward, removing the debris and impurities adhering to the cutting blade 6, and preventing the cutting blade 6 from deviating in size during the next cut. By setting a pair of first placement plates 9 and a pair of second placement plates 10 at the top of the plate 3, the worker places the material board after placing it on the first placement plates 9 and the second placement plates 10. The cylinder extension rod 7 drives the cutting blade 6 downward to cut the material board. A pair of first motors 16 continuously drive a pair of cleaning brushes 15 to rotate within the first groove 11. When the cutting blade 6 enters between a pair of first placement plates 9, the continuously rotating cleaning brushes 15 clean both sides of the cutting blade 6 after it enters, thus completing the cleaning work. By opening a second groove 20 at the top of the flat plate 3 and installing a power component within the second groove 20, when the power component drives the first toothed plate 21 downward, the clamping plate 22 gradually contacts the material board and clamps and fixes the material board, ensuring that the material board does not move during the cutting process. By installing a second motor 23 within the second groove 20, when the operator starts the second motor 23, the first rotating rod 24 will drive a pair of gears 19 to mesh with a pair of first toothed plates 21 inside the second groove 20, causing the pair of first toothed plates 21 to move downwards. When the clamping plate 22 contacts the material plate, it clamps and fixes the material plate. By installing a slidingly connected second toothed plate 28 on the inner sidewall of the second groove 20, when the gear 19 meshes with the second toothed plate 28, the second toothed plate 28 will move downwards or upwards. Because the plate 3 can slide on the support plate 1, when the operator pushes the plate 3 back into the equipment, it can be moved by the first rotating rod 24. The second motor 23 drives the second toothed plate 28 to move upward, causing the T-shaped locking block 31 to enter the T-shaped locking groove 30, restricting the plate 3 and preventing it from moving further. This prevents movement during material cutting and avoids problems in the cutting process. After cutting is completed, the power component reverses, causing the T-shaped locking block 31 to move out of the T-shaped locking groove 30, restoring the plate 3 to its moving function. The operator can then pull the plate 3 outward to easily remove the cut material from the plate 3. By setting anti-slip pads on the clamping plate 22, the friction between the clamping plate 22 and the clamped object can be increased, thereby enhancing the stability of the clamping.
