Description

Technical Field

[0001] This utility model relates to the field of silicone product processing technology, specifically a high-precision automatic silicone product cutting machine. Background Technology

[0002] Silica gel is a highly active adsorbent material, belonging to the amorphous substance. It is insoluble in water and any solvent, non-toxic and odorless, and chemically stable. Except for strong alkalis and hydrofluoric acid, it does not react with any substance. Due to its high adsorption capacity, thermal stability, and chemical stability, silica gel products have many advantages, including wear resistance, corrosion resistance, high temperature resistance, environmental friendliness and non-toxicity, softness and comfort, sealing and leak prevention, waterproofing and moisture-proofing, insulation and pressure resistance, anti-slip and shock absorption, etc., and are therefore widely used in various fields.

[0003] The "Automatic Cutting Machine for Silicone Products" disclosed in application number "202121213246.9" includes: a support assembly comprising a base plate with a placement opening for placing silicone products, a pair of support columns vertically fixed to the base plate, and a mounting plate horizontally fixed to the upper ends of the two support columns; a cutting assembly for cutting silicone products, the cutting assembly being vertically slidably mounted on the two support columns with its blade facing the base plate; a pushing component for reciprocatingly pushing the cutting assembly close to the base plate, the pushing component being vertically mounted on the mounting plate; and a reset component for resetting the cutting assembly after pushing the component away from the base plate. In this invention, under the action of the cutter, the reciprocating lead screw, and the spring, the cutter can move up and down reciprocally, thereby achieving the effect of automatically cutting and trimming the silicone products in the placement opening.

[0004] However, the above method still has the following drawbacks: the cutter driven by the reciprocating screw can cut silicone products, but since silicone is a soft and highly elastic material, when the cutter applies pressure, the silicone is prone to squeezing or shifting, resulting in uneven or tilted cuts, which reduces the cutting accuracy of silicone products.

The blade 18, the cutting groove 2, and the central groove 24 are located on the same vertical plane. The slide rails 7 and the sliders 6 can guide the slide plate 4 and prevent the slide plate 4 from tilting. The cutting groove 2 can prevent the blade 18 from colliding with the cutting table 1. The central groove 24 can prevent the blade 18 from colliding with the pressure plate 21 and ensure the cutting activity of the blade 18 on the silicone.

[0030] In this embodiment, preferably, a support frame 20 is fixedly provided at the top of the guide post 22, and the two sides of the top of the support frame 20 are respectively fixedly connected to the bottom of the two adjustment plates 10. The guide post 22 is slidably connected to the adjustment plates 10. The blade 18 is located inside the support frame 20, and the spring 23 is located between the support frame 20 and the pressure plate 21. The support frame 20 can limit the guide post 22, and the spring 23 can provide support for the pressure plate 21.

[0031] In use, the silicone product is first placed on the cutting table 1, and then the slide plate 4 is driven down by the hydraulic cylinder 5. The slide plate 4 can drive the pressure plate 21 and the blade 18 down. Under the support of the spring 23, the pressure plate 21 can contact the silicone product before the blade 18 and can compress the spring 23. The spring 23 can transmit the reaction force to the silicone product through the pressure plate 21. When the blade 18 cuts the silicone product, it can pass through the central groove 24 of the pressure plate 21. The pressure plate 21 can stabilize the silicone, reduce the movement of the silicone during cutting, and make the cutting force evenly distributed, ensuring a straight cut and avoiding the tilting of the cut, thus improving the cutting accuracy of the silicone product.

[0032] When it is necessary to adjust the pressure applied to the silicone product by the pressure plate 21, the operator drives the worm gear 1202 through the motor 1201 of the drive assembly 12. The worm gear 1202 can increase the torque through the worm wheel 1203, which can drive the bidirectional lead screw 11 to rotate. The bidirectional lead screw 11 can be converted into the linear motion of the slide table 1601 through the threaded sleeve 1602. The protrusion 1603 and the guide rail 14 can guide the slide table 1601. The slide table 1601 can drive the toothed block 1606 to move horizontally through the smooth rod 1604. By separating the toothed block 1606 from the tooth groove 19 of the adjustment plate 10, the adjustment plate 10 can be slid and the height of the adjustment plate 10 can be adjusted.

[0033] After the height of the adjusting plate 10 is adjusted, the motor 1201 drives the worm gear 1202 in the opposite direction, so that the toothed block 1606 engages with the toothed groove 19 of the adjusting plate 10, thereby fixing the adjusting plate 10. This allows the distance between the pressure plate 21 and the blade 18 to be adjusted, which in turn changes the degree of compression of the spring 23, thus adjusting the pressure on the silicone product.

[0034] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
