Description

Technical Field

[0001] This utility model relates to the field of silicone production and processing, specifically to a silicone production molding cutting device. Background Technology

[0002] In the field of silicone material processing, the precision and stability of cutting equipment directly affect the quality of the final product and production efficiency. With the widespread application of silicone products in electronic seals, medical consumables, and daily consumer goods, the market has placed higher demands on the cutting precision, processing adaptability, and ease of operation of silicone molded parts. Traditional cutting equipment, in dealing with diverse product shapes, materials of varying thicknesses, and complex process requirements, has gradually revealed structural defects and functional limitations.

[0003] Existing silicone cutting equipment generally suffers from the following shortcomings: the cutting blade angle is fixed, making it difficult to flexibly adjust according to the product's contour characteristics, thus limiting the equipment's applicability; the single-guide support structure is prone to offset or vibration during lifting, affecting the straightness of the cutting trajectory and causing burrs or dimensional deviations on the silicone edges; the linkage between the pressure plate mechanism and the cutting blade is insufficient, failing to effectively fix the material before cutting, and easily causing quality problems due to material movement during processing; the relative position adjustment mechanism between the pressure plate and the cutting blade is complex, making it difficult to quickly adapt to the processing needs of silicone of different thicknesses; when the cutting blade resets, the synchronous lifting of the pressure plate mechanism causes the silicone material to be carried away from the worktable due to negative pressure adsorption or adhesion, damaging the flatness of the cut surface and affecting the stability of subsequent processes. These technical bottlenecks restrict the processing efficiency and yield of silicone cutting equipment, becoming a technical problem that the industry urgently needs to solve. Utility Model Content

[0004] The purpose of this invention is to address the above-mentioned shortcomings by providing a silicone cutting device for silicone production molding. This device includes a pressing mechanism and an adjusting mechanism, which solves the technical problems of existing technologies, such as limited device functionality, inability to meet cutting requirements, and the upward movement of silicone, which affects product quality.

[0005] The objective of this utility model is achieved through the following means:

[0006] A silicone molding cutting device includes a worktable. Feeding rollers are rotatably connected to the inner cavity of the worktable. A support frame is mounted on the upper surface of the worktable, and a hydraulic rod is added to the upper surface of the support frame. A lifting seat is connected to the upper part of the inner cavity of the support frame, and the lifting seat is connected to the telescopic end of the hydraulic rod. A rotating shaft is rotatably connected to the lower surface of the lifting seat, and a drive motor is coaxially connected to the end of the rotating shaft. A knife holder is connected to the lower surface of the rotating shaft, and a cutting blade is mounted on the lower surface of the knife holder. Limit grooves are formed on the front and rear of the inner wall of the support frame. Sliding rods are slidably connected to the inner cavities of the limit grooves. Elastic clamps are evenly installed on the lower part of the left and right inner walls of the limit grooves. The sliding rods are slidably connected to the lifting seat. A dome plate and a connecting plate are respectively installed on the top and surface of the sliding rods. A sliding block is installed at the bottom of the sliding rod, and a pressure plate is added to the back of the sliding block. Positioning holes are evenly formed on the left and right outer sides of the sliding block.

[0007] The feeding roller moves the silicone to the cutting position on the worktable. The hydraulic rod on the support frame lowers the lifting seat, and the drive motor rotates the shaft on the lifting seat to adjust the tilt angle of the blade holder and the cutting blade to meet the bevel cutting requirements of the silicone. The sliding rod descends with the lifting seat through the dome plate in the limiting groove. The sliding block descends along the limiting groove with the sliding rod until it stops above the elastic clamp. The lifting seat continues to descend under the action of the hydraulic rod, and the sliding block continues to descend under the action of the connecting plate and the sliding rod to squeeze the elastic clamp. After the sliding rod descends to a certain extent, the elastic clamp is inserted into the positioning hole. At this time, the pressure plate is in contact with the upper surface of the silicone, and the cutting blade has finished cutting the silicone. When the hydraulic rod drives the blade holder and cutting blade to reset and rise via the lifting seat, the lifting seat separates from the ring connecting plate and, after rising to a certain extent, fits against the dome plate, driving the sliding rod to rise along the limiting groove. This separates the sliding block from the elastic chuck, preventing the silicone from rising when the cutting blade resets. On the one hand, this not only improves the functionality of the device and meets cutting requirements but also prevents the silicone from rising, ensuring product quality. On the other hand, compared to the traditional method of using springs to press the material, this structure has a longer service life and is easier to operate. At the same time, the combined use of the limiting groove and the sliding rod can limit the lifting seat, preventing the lifting seat and its connecting structure from shifting during the lifting process.

[0008] Furthermore, the support frame plate has an overall U-shaped design, and the support frame plate is connected to the front and back of the workbench.

[0009] The support frame provides stable support for the connecting structure on the workbench.

[0010] Furthermore, the sliding connection between the sliding rod and the lifting seat is located between the dome plate and the ring plate.

[0011] The lifting platform can move in the same direction via the dome plate and the ring connecting plate, which in turn drive the sliding rod.

[0012] Furthermore, the shape and position of the elastic card head correspond to those of the positioning card hole, and the elastic card head is engaged with the positioning card hole.

[0013] After the elastic card head is inserted into the positioning card hole, the sliding block is connected to the limiting groove.

[0014] Furthermore, positioning grooves are provided on the lower part of both the front and back sides of the support frame plate, and scale plates are slidably connected to the inner cavity of each positioning groove.

[0015] The scale plate can be moved along the positioning groove on the support frame plate.

[0016] Furthermore, positioning guide rails are installed on both the upper and lower surfaces of the scale plate, and an outer connecting plate is installed on the outer end of the scale plate.

[0017] When the feed roller moves the silicone on the worktable to the cutting position, the end of the silicone moves the outer connecting plate outward on the worktable. The outer connecting plate then moves the scale plate and the positioning cam along the positioning groove outward, thus facilitating the determination of the silicone cutting length.

[0018] The beneficial effects of this utility model are:

[0019] The connection between the drive motor and the rotating shaft in this solution enables the cutting blade to have a rotation adjustment function, allowing for flexible adjustment of the cutting angle according to the product shape requirements, thus improving the applicability of the equipment. The sliding fit structure of the limiting groove and the sliding rod provides dual guide support for the lifting seat. Combined with the locking and fixing of the elastic clamp and the positioning clamp hole, it effectively prevents the lifting seat from shifting or shaking during the cutting process, ensuring the straightness of the cutting trajectory. The pressure plate set at the bottom of the sliding block can pre-press the silicone material before cutting, preventing material movement during cutting from causing edge burrs or dimensional deviations. At the same time, the elastic locking design of the elastic clamp and the positioning clamp hole facilitates quick adjustment of the relative position of the pressure plate and the cutting blade, adapting to the processing requirements of silicone of different thicknesses. Even when the cutting blade completes the cutting and returns to its original position, the pressure plate still maintains the pressure on the silicone through the elastic locking structure until the cutting blade is completely detached from the material surface. This effectively avoids the silicone being carried away from the worktable due to negative pressure adsorption or material adhesion during the cutting blade's ascent, thereby ensuring the flatness of the cut surface and the stability of subsequent processing steps.

[0027] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0028] In this embodiment, refer to Figures 1-6 The specific implementation of the silicone production molding cutting device includes a worktable 1, a feeding roller 2 rotatably connected to the inner cavity of the worktable 1, a support frame plate 3 installed on the upper surface of the worktable 1, a hydraulic rod 4 added to the upper surface of the support frame plate 3, a lifting seat 5 connected to the upper part of the inner cavity of the support frame plate 3, the lifting seat 5 being connected to the telescopic end of the hydraulic rod 4, a rotating shaft 6 rotatably connected to the lower surface of the lifting seat 5, and a drive motor 7 coaxially connected to the end of the rotating shaft 6;

[0029] A blade holder 8 is connected to the lower surface of the rotating shaft 6, and a cutting blade 9 is installed on the lower surface of the blade holder 8. Limiting grooves 10 are opened on the front and back of the inner wall of the support frame plate 3. Sliding rods 11 are slidably connected to the inner cavity of the limiting grooves 10. Elastic clamps 17 are evenly installed on the lower part of the left and right inner walls of the limiting grooves 10. The sliding rods 11 are slidably connected to the lifting seat 5. A dome plate 12 and a ring connecting plate 13 are respectively installed on the top and surface of the sliding rods 11. A sliding block 14 is installed at the bottom of the sliding rod 11. A pressure plate 15 is added to the back of the sliding block 14. Positioning clamping holes 16 are evenly opened on the left and right outer sides of the sliding block 14. The feeding roller 2 moves the silicone to the cutting position on the worktable 1. The hydraulic rod 4 drives the lifting seat 5 to descend on the support frame plate 3. The drive motor 7 drives the rotating shaft 6 to rotate on the lifting seat 5, adjusting the tilt angle of the blade holder 8 and the cutting blade 9 to meet the requirements of the silicone bevel cutting.

[0030] The sliding rod 11 descends with the lifting seat 5 through the dome plate 12 within the limiting groove 10. The sliding block 14 descends along the limiting groove 10 with the sliding rod 11 until it stops above the elastic clamp 17. The lifting seat 5 continues to descend under the drive of the hydraulic rod 4, and under the action of the ring connecting plate 13 and the sliding rod 11, it drives the sliding block 14 to continue to descend and squeeze the elastic clamp 17. After the sliding rod 11 descends to a certain extent, the elastic clamp 17 is inserted into the positioning hole 16. At this time, the pressure plate 15 is in contact with the upper surface of the silicone, and the cutting blade 9 has finished cutting the silicone.

[0031] When the hydraulic rod 4 drives the knife holder 8 and the cutting blade 9 to reset and rise through the lifting seat 5, the lifting seat 5 separates from the ring connecting plate 13 and, after rising to a certain extent, fits against the dome plate 12, driving the sliding rod 11 to rise along the limiting groove 10, causing the sliding block 14 to separate from the elastic clamp 17. This prevents the silicone from rising when the cutting blade 9 resets and rises. On the one hand, this not only improves the functionality of the device and meets the cutting requirements, but also prevents the silicone from rising, ensuring product quality. On the other hand, compared with the traditional use of springs to press the material, this structure has a longer service life and is easier to operate. At the same time, the use of the limiting groove 10 and the sliding rod 11 can limit the lifting seat 5, preventing the lifting seat 5 and its connecting structure from shifting during the lifting process.

[0032] like Figure 1 As shown, the support frame 3 has an overall U-shaped design and is connected to the front and back of the worktable 1. The support frame 3 provides stable support for the connecting structure on the worktable 1.

[0033] like Figure 5 and Figure 6 As shown, the sliding rod 11 and the lifting seat 5 are slidably connected between the dome plate 12 and the annular connecting plate 13. This allows the lifting seat 5 to move the sliding rod 11 in the same direction via the dome plate 12 and the annular connecting plate 13. The elastic locking head 17 corresponds to the positioning locking hole 16 in shape and position, and the elastic locking head 17 is engaged with the positioning locking hole 16. After the elastic locking head 17 is engaged in the positioning locking hole 16, the sliding block 14 is connected to the limiting groove 10. Positioning grooves 19 are provided on the lower part of both the front and back sides of the support frame plate 3, and scale plates 20 are slidably connected to the inner cavity of each positioning groove 19. The scale plates 20 can be moved along the positioning grooves 19 on the support frame plate 3. Positioning guide rails 18 are installed on the upper and lower surfaces of the scale plates 20, and an outer connecting plate 21 is installed on the outer end of the scale plates 20. When the feeding roller 2 moves the silicone on the worktable 1 to the cutting position, the end of the silicone moves the outer connecting plate 21 outward on the worktable 1. The outer connecting plate 21 moves the scale plate 20 and the positioning cam 18 outward along the positioning groove 19, thereby facilitating the determination of the cutting length of the silicone.

[0034] The working process of a silicone production molding cutting device in this embodiment is as follows: The feeding roller 2 moves the silicone to the cutting position on the worktable 1. The hydraulic rod 4 drives the lifting seat 5 to descend on the support frame plate 3. The drive motor 7 drives the rotating shaft 6 to rotate on the lifting seat 5, adjusting the tilt angle of the knife holder 8 and the cutting blade 9 to meet the requirements of the silicone's bevel cutting. The sliding rod 11 descends with the lifting seat 5 through the dome plate 12 in the limiting groove 10. The sliding block 14 descends along the limiting groove 10 with the sliding rod 11 until it stops above the elastic clamp 17. The lifting seat 5 continues to descend under the drive of the hydraulic rod 4, and the sliding block 14 continues to descend under the action of the connecting plate 13 and the sliding rod 11 to squeeze the elastic clamp 17. After the sliding rod 11 descends to a certain extent... The elastic clip 17 is inserted into the positioning clip hole 16. At this time, the pressure plate 15 is in contact with the upper surface of the silicone. After the cutting blade 9 finishes cutting the silicone, when the hydraulic rod 4 drives the blade holder 8 and the cutting blade 9 to reset and rise through the lifting seat 5, the lifting seat 5 separates from the ring connecting plate 13 and, after rising to a certain extent, is in contact with the dome plate 12, which drives the sliding rod 11 to rise along the limiting groove 10, so that the sliding block 14 separates from the elastic clip 17, preventing the silicone from rising when the cutting blade 9 resets and rises. When the feeding roller 2 moves the silicone on the worktable 1 to the cutting position, the end of the silicone moves the outer connecting plate 21 outward on the worktable 1. The outer connecting plate 21 moves the scale plate 20 and the positioning convex rail 18 outward along the positioning groove 19, which facilitates the determination of the cutting length of the silicone.

[0035] The above description, in conjunction with specific preferred embodiments, provides a further detailed explanation of the present invention. It should not be construed that the specific implementation of the present invention is limited to these descriptions. For those skilled in the art, various simple deductions or substitutions can be made without departing from the concept of the present invention, and all such modifications and substitutions should be considered within the scope of protection of the present invention.
