Description

Technical Field

[0001] This invention relates to the field of silicone pad production and processing technology, specifically to a slicing machine for producing and processing silicone pads with adjustable thickness. Background Technology

[0002] With the development of industrial automation and precision manufacturing, silicone gaskets are widely used in smart terminal devices, precision instruments and high-end sealing scenarios due to their excellent resilience, resistance to high and low temperatures and biocompatibility. In the field of smart sealing, the thickness uniformity and dimensional accuracy of silicone gaskets directly affect the airtightness, waterproof rating and long-term reliability of the sealing structure. Therefore, stringent requirements are placed on the processing accuracy of silicone gaskets.

[0003] In the prior art, various adjustable-thickness slicing devices have been disclosed for slicing soft rubber or silicone materials. For example, Chinese patent CN218083007U discloses an automatic slicing device for soft rubber. This device places the rubber raw material on a storage plate, uses a pusher plate to push the material to a baffle plate for blocking and positioning, and uses a hydraulic cylinder to adjust the distance between the baffle plate and the fixed platform to determine the slicing thickness. This type of equipment achieves adjustable slicing thickness to a certain extent, meeting the production needs of products with different specifications. However, it also has some problems: First, due to the significant viscoelastic properties of silicone material, it is prone to deformation and rebound during the cutting process. When the cutter contacts the silicone surface, the silicone is subjected to shearing force and is prone to lateral slippage or local bulging. The cutting point position is easily offset, resulting in inconsistent thickness of the actual cut gasket, which affects the fitting accuracy during intelligent sealing assembly. Second, the cutting of silicone will generate fine glue debris, dust or adhesive strips. If the cut is not cleaned in time, these impurities are easy to get stuck in the cut surface or adhere to the cut edge during the next cut, forming small bulges on the cut surface, resulting in inconsistent thickness at different positions of the same silicone gasket.

[0004] To address the aforementioned issues, there is an urgent need for innovative design based on the existing slicing machine used for producing and processing adjustable thickness silicone pads. Summary of the Invention

[0005] The purpose of this invention is to provide a slicing machine for producing and processing silicone pads with adjustable thickness, so as to solve the problems mentioned in the background art of existing slicing machines of this kind that are not conducive to suppressing the elastic deformation and displacement of silicone, and that the kerf is not cleaned in time, which easily causes thickness deviation and slicing defects.

The two sides inside the frame are evenly connected to the clamping plate through spring sleeves.

[0010] Preferably, the top of each bracket is connected to the center of both sides of the swing member via a pivot, and a second drive wheel is provided at the end of the swing member away from the pressure plate. A second wedge is provided on both sides of the clamping plate, and the inclined surface of the second wedge cooperates with the second drive wheel respectively.

[0011] Preferably, a slit is provided on the slicer body between the baffle and the silicone body, and an air guide pipe is provided on the bottom of the slicer body on one side below the slit via a fixing frame.

[0012] Preferably, the air nozzles are evenly distributed on the side of the air guide tube near the cut, and the air nozzles are inclined toward the cut. Air passages are provided at both ends inside the air guide tube, and the air nozzles are all connected to the air passages.

[0013] Preferably, a valve body is provided at one end of each air passage, and a valve core is provided inside each valve body.

[0014] Preferably, each of the clamping plates is provided with a sliding member at its bottom end, and each of the slicer bodies below the clamping plates is provided with a slot. The sliding member passes through the slot and slides and translates along the slot. Each of the bottom ends of the slicer body near the sliding member of the valve body is provided with a magnetic plate through a return spring, and the end of the magnetic plate near the valve core is connected to the valve core through a valve rod. Each of the sliding members near the magnetic plate is provided with a permanent magnet.

[0015] Preferably, a fixed seat is provided on the slicer body at the end of the baffle away from the silicone body, and a screw passes through the center of the fixed seat laterally. One end of the screw is connected to the baffle. Limit sleeves are provided on both sides of the slicer body, and a sliding rod passes through the inside of each limit sleeve. One end of each sliding rod is connected to the baffle.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows: This adjustable thickness silicone pad production and processing slicing machine, through pre-marking and positioning with a scribing knife, achieving lateral and top three-dimensional clamping through wedge linkage, and double air blowing cleaning at the front and rear of the air path, effectively suppresses slippage deformation during silicone cutting and reduces thickness deviation. The specific details are as follows: 1. The slicing machine consists of a main body, a silicone body, a baffle, a pusher plate, and a slicing mechanism. The slicing mechanism includes a lifting frame, a cutter, a drive box, a rack, a gear, a second lead screw, a second drive block, and a scribing blade. The baffle position is pre-adjusted, and then the silicone block is pushed to one side of the baffle by the pusher plate to complete the thickness positioning. During slicing, the cylinder drives the lifting frame to move the cutter downward. During the downward movement, the rack and gear mesh to drive the second lead screw to move the scribing blade horizontally in sync. The positioning cutting line can be pre-marked at the position to be cut on the silicone body, providing a clear cutting guide path for the actual cutter. This effectively prevents slippage, pushing, and local bulging caused by uneven friction when the cutter first contacts the silicone body, thereby reducing the thickness deviation of the slice. At the same time, the pre-marking can pre-cut the surface structure of the silicone body, reducing the resistance when the cutter enters, which helps to obtain a flat, burr-free, and string-free cut, meeting the requirements of the intelligent sealing gasket for the flatness of the sealing surface. 2. A first wedge, a first drive wheel, and a clamping plate are set up. While the lifting frame drives the cutter to cut downwards, the first wedge simultaneously pushes the clamping plates on both sides to move closer to and clamp the silicone body. Before the actual cutting, a double-sided rigid constraint is formed on the silicone block, which effectively prevents lateral slippage and elastic rebound when the cutter contacts the silicone, thereby ensuring that the slice thickness is closer to the preset value. At the same time, a bracket, a second wedge, a second drive wheel, a rotating shaft, a swinging component, and a pressure plate are set up. During the clamping process, the clamping plate drives the second wedge to gradually press against the second drive wheel. The rotating shaft and the swinging component drive the pressure plate to press down, clamping the silicone body on both sides while pressing the top, forming a three-dimensional limiting structure on the sides and top. This comprehensively restricts the bulging, warping, and elastic deformation of the silicone body during cutting, further preventing the thickness of the silicone from changing during the cutting process. 3. The system includes a sliding component, a permanent magnet, a return spring, a valve body, a valve core, an air guide tube, an air passage, and an air nozzle. The air guide tube is located below the cut. The sliding component is connected to the bottom of the clamping plate. Before the clamping plate moves towards the silicone body and holds it in place, it moves the bottom sliding component. The permanent magnet attracts the silicone body, and the return spring drives the valve core to open the air passage. Compressed air is sprayed out in advance through the air guide tube and the air nozzle to pre-clean the dust and residual silicone debris in the cut area, preventing impurities from embedding in the cutting position. During the slicing process and when the clamping plate is released and reset, the sliding component triggers the valve core again to open the air passage, blowing air into the cut to clean debris a second time. This achieves pre-treatment before slicing and post-slicing cleaning, providing double protection for slicing quality and preventing impurities from being trapped in the cut surface or attached to the cut edge during slicing, which can cause local protrusions and further prevent deviations in slice thickness.

[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] Example 1: Please refer to Figures 1-8 This invention provides a technical solution: a slicing machine for producing and processing silicone pads with adjustable thickness, comprising: The slicer body 1 has a pusher plate 7 and a baffle plate 2 at its two ends. The table surface of the slicer body 1 between the baffle plate 2 and the pusher plate 7 is used to place the silicone body 6. The pusher plate 7 is used to push the silicone body 6 smoothly towards the baffle plate 2 to achieve the initial positioning of the silicone slice thickness. The slicer body 1 is supported by a frame 3 at the center above the slicer body 1. The slicer mechanism 4 is used to complete the pre-marking and formal cutting of the silicone body 6. In the above scheme, such as Figure 1 , Figure 8As shown, a fixed seat 202 is provided on the slicer body 1 at the end of the baffle 2 away from the silicone body 6. The fixed seat 202 is fixedly connected to the table surface of the slicer body 1 to maintain a stable position. A screw 201 is horizontally passed through the center of the fixed seat 202. The screw 201 and the fixed seat 202 are threaded together. One end of the screw 201 is fixedly connected to the side wall of the baffle 2. Limit sleeves 204 are provided on both sides of the slicer body 1. The limit sleeves 204 are fixed to the table surface of the slicer body 1. A sliding rod 203 passes through the inside of the limit sleeve 204. One end of the sliding rod 203 is fixedly connected to the side wall of the baffle 2. The sliding rod 203 and the limit sleeve 204 are in sliding fit, which plays a guiding and limiting role. When it is necessary to adjust the thickness of the silicone gasket slices, the operator rotates the screw 201. The screw 201 and the fixed seat 202 drive the baffle 2 to move smoothly along the axial direction of the slide rod 203. The cooperation between the slide rod 203 and the limit sleeve 204 can prevent the baffle 2 from shifting or tilting when it moves, ensuring that the baffle 2 is always parallel to the push plate 7, thereby ensuring that the slice thickness is uniform. After the baffle 2 moves to the position corresponding to the preset thickness, the screw 201 is stopped. The self-locking characteristic of the threaded engagement can keep the baffle 2 in a fixed position, avoiding the displacement of the baffle 2 due to vibration during the slicing process, which would affect the slice thickness accuracy and adapt to the production needs of smart sealing silicone gaskets of different specifications. like Figure 1 As shown, a first lead screw 8 is provided on the slicer body 1 on one side of the pusher plate 7. The first lead screw 8 is rotatably connected to the slicer body 1 through a bearing seat. A first drive block 9 is sleeved on the first lead screw 8. The first drive block 9 and the first lead screw 8 are threaded together. The first drive block 9 is fixedly connected to the pusher plate 7. A drive motor 10 is fixed on the slicer body 1 on one side of the first lead screw 8. The output end of the drive motor 10 is fixedly connected to one end of the first lead screw 8 through a coupling. A guide rod 13 is provided on the side of the slicer body 1 away from the first lead screw 8. The guide rod 13 is fixed to the table surface of the slicer body 1. A guide sleeve is provided on the end of the pusher plate 7 near the guide rod 13. The guide sleeve is sleeved on the outside of the guide rod 13 and forms a sliding fit with the guide rod 13. After placing the silicone body 6 on the table of the slicer body 1 between the pusher plate 7 and the baffle 2, start the drive motor 10. The output end of the drive motor 10 drives the first lead screw 8 to rotate at a constant speed. Since the first drive block 9 is threadedly engaged with the first lead screw 8 and fixed to the pusher plate 7, when the first lead screw 8 rotates, it drives the first drive block 9 to move smoothly along the axial direction of the first lead screw 8 towards the side of the baffle 2, thereby driving the pusher plate 7 to move synchronously. The cooperation between the guide rod 13 and the guide sleeve can ensure that the pusher plate 7 moves smoothly and avoid the pusher plate 7 from shifting, which would cause uneven force and misalignment of the silicone body 6. The pusher plate 7 continues to push the silicone body 6 until one side of the silicone body 6 is tightly attached to the baffle 2. At this time, the drive motor 10 stops working and remains locked. The pusher plate 7 remains in the position of pressing the silicone body 6 against the baffle 2, realizing the thickness positioning of the silicone body 6, laying the foundation for subsequent slicing operations. The contact surface between the slicer body 1 and the silicone body 6 is coated with polyethylene, which has a low coefficient of friction and facilitates pushing. like Figure 1 , Figure 2 As shown, the slicing mechanism 4 includes a lifting frame 407 located at the top of the frame 3. The lifting frame 407 can slide vertically along the inside of the frame 3. A cutter 402 is located at the center of the bottom of the lifting frame 407, with the blade facing downwards, for formally cutting the silicone body 6. A second lead screw 405 is located inside the frame 3 below the cutter 402. The second lead screw 405 is rotatably connected to the frame 3 through a bearing seat. A scribing blade 406 is located on the second lead screw 405 through a second drive block 409. The scribing blade 406 has its blade facing downwards and corresponds to the upper surface of the silicone body 6, for marking the position to be cut on the silicone body 6. The second lead screw 405 passes through the side wall of the frame 3 and is fixedly connected to a gear 403. A rack 404 meshes with one side of the gear 403. The rack 404 is arranged vertically and is fixedly connected to one end of the lifting frame 407. A drive box 401 is provided on the frame 3 outside the rack 404 and the gear 403. The drive box 401 is used to protect the rack 404 and the gear 403 to prevent dust and debris from entering and affecting the transmission stability. A cylinder 5 is fixed in the center of the top of the frame 3. The output end of the cylinder 5 is fixedly connected to the center of the top of the lifting frame 407 through a telescopic rod and is used to drive the lifting frame 407 to rise and fall vertically. After the silicone body 6 is positioned, the cylinder 5 is activated. The output end of the cylinder 5 extends, driving the lifting frame 407 and the cutter 402 to move vertically downwards simultaneously. When the lifting frame 407 moves downwards, the rack 404 fixed at one end moves downwards simultaneously. Since the rack 404 meshes with the gear 403, the downward movement of the rack 404 drives the gear 403 to rotate at a constant speed. When the gear 403 rotates, it drives the second lead screw 405 to rotate synchronously. The second lead screw 405 is threadedly engaged with the second drive block 409, thereby driving the second drive block 409 to move laterally along the axial direction of the second lead screw 405. The second drive block 409 drives the scribing knife 406 to move laterally synchronously. The blade of the scribing knife 406 contacts the upper surface of the silicone body 6, and a positioning cutting line is pre-marked at the position to be cut on the silicone body 6. Before the lower edge of the cutter 402 contacts the upper surface of the silicone body 6, the scribing blade 406 has already completed the scribing operation of the entire area to be cut. This ensures that the cutter 402 always travels along the pre-formed pre-cut lines when it officially cuts in, providing a clear cutting guide path for subsequent formal cutting. This effectively prevents slippage, pushing, and local bulging caused by uneven friction on the silicone surface when the cutter 402 first contacts the silicone body 6, thereby reducing the thickness deviation of the slice. At the same time, the scribing blade 406 pre-cuts the surface structure of the silicone body 6, which can reduce the resistance when the cutter 402 cuts in, helping to obtain a flat, burr-free, and string-free cut, meeting the stringent requirements of the smart sealing gasket for the flatness of the sealing surface. like Figure 1 , Figure 3 and Figure 4 As shown, clamping plates 14 are provided on both sides of the slicer body 1 of the silicone body 6. The clamping plates 14 correspond to the side walls of the silicone body 6 and are used to clamp the silicone body 6 laterally. The two sides inside the frame 3 are evenly connected to the clamping plates 14 through spring sleeves 15. The spring sleeves 15 are equipped with compression springs. Under normal conditions, the spring sleeves 15 are in a compressed state, pulling the clamping plates 14 away from the silicone body 6. The bottom sides of the lifting frame 407 are fixedly connected with first wedges 408. The bottom surface of the first wedges 408 is set as an inclined surface. The side of the clamping plates 14 away from the silicone body 6 is provided with a first drive wheel 11. The inclined surface of the first wedges 408 is in contact with the first drive wheel 11 to form rolling friction and reduce transmission resistance. As the lifting frame 407 drives the cutter 402 to cut downwards, the first wedges 408 on both sides of its bottom move downwards simultaneously. The inclined surfaces of the first wedges 408 continuously press the first drive wheels 11 on both sides, converting the vertical downward driving force into a horizontal thrust, pushing the clamping plates 14 on both sides towards the silicone body 6. As the lifting frame 407 continues to move downwards, the squeezing force of the first wedges 408 on the first drive wheels 11 gradually increases until the clamping plates 14 are tightly attached to the side wall of the silicone body 6, achieving lateral clamping of the silicone body 6. This clamping action is completed before the cutter 402 contacts the silicone body 6, forming a double-sided constraint on the silicone body 6 in advance, effectively preventing lateral slippage and elastic rebound when the cutter 402 contacts the silicone, thereby ensuring that the slice thickness is closer to the preset value. The profile of the first wedge 408 adopts a combination structure of inclined surface and straight surface. The inclined surface is used to contact the first drive wheel 11 in the initial downward movement and gradually push the clamping plate 14 towards the silicone body 6. When the clamping plate 14 is clamped in place with the side wall of the silicone body 6, as the first wedge 408 continues to move downward, its mating surface with the first drive wheel 11 transitions from inclined surface to straight surface. The straight surface structure forms a sliding fit with the first drive wheel 11. When this section of the profile moves in the vertical direction, it does not convert into horizontal feed. Therefore, the clamping position of the clamping plate 14 remains unchanged. This ensures that even if the cutter 402 continues to move downward after the clamping plate 14 is clamped in place, it will not continue to increase the lateral extrusion force on the silicone body 6, thus preventing hard extrusion damage to the surface of the silicone body 6. Both ends of the clamping plate 14 are equipped with swinging parts 19 on the slicer body 1 via brackets 12. The brackets 12 are fixedly connected to the table surface of the slicer body 1. The top of the brackets 12 is rotatably connected to the center of both sides of the swinging parts 19 via a rotating shaft, so that the swinging parts 19 can swing freely around the rotating shaft. The end of the swinging parts 19 near the silicone body 6 is equipped with a pressure plate 20, the bottom surface of which corresponds to the upper surface of the silicone body 6, for pressing the silicone body 6 from the top. The end of the swinging parts 19 away from the pressure plate 20 is equipped with a second drive wheel 18. The sides of the clamping plate 14 are fixedly equipped with second wedges 17, the inclined surfaces of the second wedges 17 respectively fit and cooperate with the second drive wheels 18. During the clamping process of the clamping plate 14 approaching and clamping the silicone body 6, the second wedges 17 on both sides move synchronously toward the second drive wheel 18. The inclined surface of the second wedge 17 continuously presses against the second drive wheel 18, pushing the swinging member 19 to swing around the rotation axis of the top of the bracket 12 to one side of the silicone body 6. When the swinging member 19 swings, the end of it close to the silicone body 6 rotates downward, driving the pressure plate 20 to move downward synchronously until the bottom surface of the pressure plate 20 is tightly attached to the upper surface of the silicone body 6, thus achieving top clamping of the silicone body 6. This achieves synchronous linkage between lateral clamping and top clamping, forming a three-dimensional limiting structure for the side and top, which comprehensively restricts the bulging, warping, and elastic deformation of the silicone body 6 during cutting, further preventing changes in thickness during the cutting process. Example 2 This embodiment, based on Embodiment 1, further discloses a kerf cleaning and linkage control structure to achieve dual kerf cleaning functions before and after slicing, as detailed below. Figure 5 , Figure 6 and Figure 7 As shown: A slit 21 is provided on the slicer body 1 between the baffle 2 and the silicone body 6. The slit 21 is arranged along the cutting direction of the silicone body 6 to provide cutting space for the cutter 402 and prevent the cutter 402 from contacting the table surface of the slicer body 1 and causing damage to the blade. An air guide pipe 22 is provided on the bottom of the slicer body 1 below the slit 21 via a fixing bracket. The air guide pipe 22 is arranged horizontally, and air nozzles 220 are evenly distributed on the side of the air guide pipe 22 near the slit 21. 2. The air nozzle 2202 is inclined toward the cut 21 to ensure that the airflow can blow toward the cut 21 area. The two ends of the air guide tube 22 are respectively provided with air passages 2201. The air nozzles 2202 are all connected to the air passages 2201. One end of the air passage 2201 is provided with a valve body 2203. The valve body 2203 is fixedly connected to the air guide tube 22. The valve core 2204 is provided inside the valve body 2203. The valve core 2204 is used to control the opening and closing of the air passage 2201. Each clamping plate 14 has a sliding member 16 at its bottom end. The slicer body 1 below the clamping plate 14 has a slot 23. The slot 23 is arranged along the moving direction of the clamping plate 14. The sliding member 16 passes through the slot 23 and forms a sliding fit with the slot 23, allowing it to move smoothly along the slot 23. The bottom of the slicer body 1 near the sliding member 16 of the valve body 2203 has a magnetic plate 2206 provided by a return spring 2205. The return spring 2205 is normally in an extended state, pushing the magnetic plate 2206 to press against the side near the valve body 2203. The end of the magnetic plate 2206 near the valve core 2204 is connected to the valve core 2204 through a valve stem. The end of the sliding member 16 near the magnetic plate 2206 is provided with a permanent magnet 1601. The permanent magnet 1601 and the magnetic plate 2206 can magnetically attract each other. Before the clamping plate 14 moves towards and clamps the silicone body 6 into place, it drives the bottom sliding member 16 to move along the slot 23 towards one side of the silicone body 6. When the sliding member 16 moves to a position close to the magnetic plate 2206, the magnetic attraction force generated by the permanent magnet 1601 overcomes the tension of the return spring 2205, attracting the magnetic plate 2206 to move towards the sliding member 16. The magnetic plate 2206 drives the valve core 2204 to move inside the valve body 2203 through the valve stem, thus opening the air passage 2201. At this time, the external... Compressed air enters the air passage 2201 through the air guide tube 22, and then is sprayed out at an angle towards the slit 21 area through the air nozzle 2202. This pre-cleans the dust and residual silicone debris in the slit 21 area, preventing impurities from embedding in the cutting position and preventing impurities from getting stuck in the cutting surface or adhering to the edge of the cut during slicing, which would cause local protrusions. This further prevents deviations in slice thickness. When the clamping plate 14 is in place, the sliding member 16 separates from the magnetic plate 2206, causing the air passage 2201 to close and stop blowing air, thus preventing it from affecting the slicing. After slicing, the output end of cylinder 5 retracts, driving the lifting frame 407, cutter 402 and first wedge 408 to reset upwards simultaneously. The squeezing force of the first wedge 408 on the first drive wheel 11 disappears. Under the elastic force of the compression spring inside the spring sleeve 15, the clamping plate 14 resets to the side away from the silicone body 6. The clamping plate 14 drives the sliding part 16 to move in the opposite direction along the slot 23. When passing the magnetic plate 2206, the valve core 2204 is triggered again to briefly open the air passage 2201, and the cut slit 21 is blown away from the cut slit 21 to remove the silicone chips. This achieves pre-treatment before slicing and post-slicing cleaning, ensuring the quality of the slices. After that, the cut silicone pad is taken out, and the drive motor 10 continues to drive the first lead screw 8 to rotate. The silicone body 6 is pushed to the side of the baffle 2 by the pusher plate 7 to be blocked, and the next slicing operation is carried out.

Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
