Description

Technical Field

[0001] This utility model relates to the technical field of silicone product processing equipment, and in particular to a silicone sealing gasket production and cutting device. Background Technology

[0002] In the production process of silicone gaskets, the cutting step is crucial, directly affecting not only the product's precision but also its appearance quality. This step demands highly precise and meticulous work from operators to ensure that the size and shape of each silicone gasket meet design requirements. During the cutting process, the tools and equipment used must be kept in optimal condition to ensure smooth cut edges and dimensional accuracy. Any slight deviation may result in the gasket not being installed correctly or failing to achieve the expected sealing effect.

[0003] Traditional cutting devices are not suitable for silicone materials that are soft and prone to wrinkling. Traditional flattening mechanisms are mostly fixed structures and cannot adjust the pressure and position according to the thickness of the material, resulting in poor flattening effect and skewed cutting edges. A large amount of silicone debris is generated during the cutting process. This debris is easy to adhere to the workbench surface or the material, which not only affects the subsequent cutting accuracy, but also requires frequent manual cleaning, increasing the operation process and time cost.

Detailed Implementation

[0017] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0018] Reference Figure 1-6 This utility model discloses a silicone sealing gasket production cutting device, comprising a worktable 1, a lifting and grooving mechanism 2, a flattening mechanism 3, and a cutting mechanism 5. The lifting and grooving mechanism 2 includes a first grooving 17 on the surface of the worktable 1, with a fixed plate 20 vertically mounted inside the first grooving 17. Several dust suction holes 21 are evenly distributed on both sides of the first grooving 17. The flattening mechanism 3 includes a third fixed box 36 fixedly mounted on the lower surface of the worktable 1. Supports 35 are slidably mounted on both sides of the third fixed box 36. First electric telescopic rods 15 are fixedly mounted on the upper surfaces of the two supports 35. Connecting blocks 14 are fixedly mounted at the other ends of the two first electric telescopic rods 15. A first rotating shaft 18 is rotatably mounted in the middle of the two connecting blocks 14, and a pressure roller 16 is fixedly mounted on the surface of the first rotating shaft 18. The fixed plate 20 provides support during the flattening stage, makes way during the cutting stage, and also serves as a channel for debris cleaning. Before flattening, the third electric telescopic rod 24 drives the fixed plate 20 to rise from the first groove 17, lifting the silicone material to a height that matches the pressure roller 16. This prevents the material from sinking into the gap of the worktable 1 due to its softness and ensures that the wrinkles are fully extended. The function of the second auxiliary telescopic rod 23 is to ensure the horizontality of the fixed plate 20 during lifting and lowering, preventing uneven force on the material caused by unilateral tilting.

[0019] Before cutting, the fixing plate 20 retracts into the first cutting groove 17 via the third electric telescopic rod 24, so that the material adheres to the surface of the workbench 1. Vertical cutting space is reserved for the cutting blade 38 to avoid collision between the blade and the fixing plate 20. The dust suction holes 21 on both sides of the first cutting groove 17 allow the debris generated during cutting to be directly sucked into the second fixing box 33.

[0020] The third dual-axis motor 25 drives the second rotating shafts 26 on both sides to rotate. Through the reversal of the first bevel gear 27 and the second bevel gear 28, the second lead screw 30 rotates, causing the second slider 29 to slide laterally along the support 35. The first electric telescopic rod 15 controls the downward pressure of the pressure roller 16 by its extension / retraction. For thin silicone, it reduces pressure to avoid excessive stretching; for thick or deeply wrinkled materials, it increases pressure to enhance the crushing effect. The pressure roller 16 rotates freely via the first rotating shaft 18, converting sliding friction into rolling friction. This reduces damage to the silicone surface and allows the wrinkles to gradually extend through continuous crushing. Both first electric telescopic rods 15 rise and fall simultaneously.

[0021] The first motor 9 on the gantry 4 drives the reciprocating lead screw 6, which in turn moves the first slider 7 and the first fixed box 8. Longitudinal movement is achieved by the second motor 11 inside the first fixed box 8 driving the third lead screw 41, which in turn moves the slide plate 10 and the hollow rod 40. This dual-movement coordination allows the cutting blade 38 to complete cuts along any trajectory in the horizontal plane, meeting the processing requirements of sealing gaskets of different shapes. The fourth motor 37 drives the cutting blade 38 to rotate at high speed via the third rotating shaft 39, coordinating with the movement trajectory to complete the cut. The enclosed design of the fourth fixed box 42 reduces the splashing of cutting debris, indirectly improving the collection efficiency of the dust extraction system.

[0022] The cutting mechanism 5 includes a gantry frame 4 fixedly mounted on the upper surface of the worktable 1, a first fixed box 8 slidably mounted on the lower surface of the gantry frame 4, a hollow rod 40 mounted on the telescopic end of the first fixed box 8, and a fourth fixed box 42 fixedly mounted on the other end of the hollow rod 40. A third electric telescopic rod 24 is fixedly mounted on the lower surface of the fixed plate 20, and second auxiliary telescopic rods 23 are fixedly mounted on both sides of the third electric telescopic rod 24. The other ends of the two second auxiliary telescopic rods 23 and the third electric telescopic rod 24 are all fixedly mounted on the inner wall of the first cutting groove 17.

[0023] A second fixed box 33 is fixedly installed on the lower surface of the workbench 1. Connecting pipes 34 are fixedly installed through both sides of the second fixed box 33. The dust suction hole 21 is connected to the second fixed box 33 through the connecting pipes 34. An exhaust sleeve 31 is fixedly installed through the lower surface of the second fixed box 33. A filter plate 32 is slidably installed on one side of the second fixed box 33.

[0024] The third fixed box 36 is internally fixedly equipped with a third dual-axis motor 25. The output ends of the third dual-axis motor 25 are all fixedly connected to the second rotating shafts 26. The other ends of the two second rotating shafts 26 are fixedly equipped with first bevel gears 27. The two first bevel gears 27 are meshed with second bevel gears 28 on one side. The second bevel gears 28 are fixedly connected to second lead screws 30. The surfaces of the two second lead screws 30 are threadedly connected to second sliders 29. The side of the second sliders 29 is fixedly equipped with brackets 35. One end of the two brackets 35 slides through both sides of the third fixed box 36.

[0025] A second electric telescopic rod 19 is fixedly installed on the lower surface of the gantry frame 4. A first auxiliary telescopic rod 12 is fixedly installed on both sides of the second electric telescopic rod 19. A pressure plate 13 is fixedly installed at the other end of the two first auxiliary telescopic rods 12 and the second electric telescopic rod 19.

[0026] A first motor 9 is fixedly installed on the inner wall of the gantry frame 4. A reciprocating lead screw 6 is fixedly connected to the output end of the first motor 9. A first slider 7 is adapted to the surface of the reciprocating lead screw 6. A first fixed box 8 is fixedly installed on the lower surface of the first slider 7. A third lead screw 41 is fixedly connected to the output end of a second motor 11 on the inner wall of the first fixed box 8. A slide plate 10 is threadedly connected to the surface of the third lead screw 41. A hollow rod 40 is fixedly installed on the lower surface of the slide plate 10.

[0027] The fourth fixed box 42 is fixedly equipped with a fourth motor 37. The output end of the fourth motor 37 is fixedly connected to a third rotating shaft 39. A cutting blade 38 is fixedly installed in the middle of the third rotating shaft 39. The cutting blade 38 rotates through the fourth fixed box 42. The other end of the third rotating shaft 39 is rotatably connected to the inner wall of the fourth fixed box 42.

[0028] Working principle: Lay the silicone material to be cut flat on the surface of the worktable 1, ensuring that the material covers the area of ​​the first cutting groove 17, and complete the initial positioning.

[0029] Start the third electric telescopic rod 24 to lift the fixed plate 20 from the first groove 17 until the upper surface of the material contacts the lower surface of the pressure roller 16; start the third dual-shaft motor 25 to drive the second lead screw 30 to rotate through bevel gear transmission, so that the bracket 35 moves laterally and the pressure roller 16 is adjusted to the position where the material is to be flattened; control the extension and retraction of the first electric telescopic rod 15 to adjust the pressing pressure of the pressure roller 16, and then push the material or control the movement of the pressure roller 16 to eliminate the wrinkles of the material by rolling and crushing the material through the pressure roller 16.

[0030] The third electric telescopic rod 24 retracts, causing the fixed plate 20 to retract into the first cutting groove 17, so that the material adheres to the surface of the workbench 1; the exhaust sleeve 31 is activated to form a negative pressure, and a debris collection channel is constructed through the dust suction hole 21 and the connecting pipe 34; at the same time, the second electric telescopic rod 19 is activated, causing the pressure plate 13 to descend, pressing and fixing the edge of the material to prevent the material from shifting during cutting.

[0031] The fourth motor 37 is started, driving the cutting blade 38 to rotate at high speed; the first motor 9 drives the reciprocating lead screw 6 to control the first fixed box 8 to move laterally, and the second motor 11 drives the third lead screw 41 to control the hollow rod 40 to move longitudinally. The two work together to make the cutting blade 38 move along the preset trajectory to complete the cutting of the silicone sealing gasket; the debris generated during the cutting process is sucked into the second fixed box 33 through the dust suction hole 21 and collected after being filtered by the filter plate 32.

[0032] After cutting, turn off all motors and exhaust sleeve 31. The second electric telescopic rod 19 retracts, causing the pressure plate 13 to rise. Remove the cut sealing gasket. Periodically remove the filter screen plate 32 on one side of the second fixed box 33, clean up the collected debris, and complete the equipment maintenance.
