Description

Technical Field

[0001] This utility model relates to the field of cutting device technology, specifically a silicone sheet fixed-length cutting device. Background Technology

[0002] In many fields such as electronic component packaging, medical device manufacturing, and food packaging, silicone sheets have become an indispensable basic material due to their excellent insulation, corrosion resistance, and flexibility. In actual production applications, silicone sheets need to be cut into standard parts of fixed length according to specific working conditions. When using silicone sheet cutting equipment, some devices lack a limiting mechanism for the silicone sheet (e.g., in the patent publication number CN218365177U entitled "A Silicone Sheet Cutting Structure," the silicone sheet cannot be positioned during cutting). This makes it easy for the silicone sheet to shift position due to the cutting blade during the cutting process, thus affecting the subsequent cutting accuracy and quality. In addition, although some improved devices are equipped with an automatic pressure plate structure, they often require a separate drive motor or cylinder as a power source, which increases the manufacturing cost of the device. On the other hand, after cutting, the silicone sheet is prone to sticking tightly to the blade or blade surface of the cutting blade body due to surface stickiness and static electricity generated during the cutting process. This requires operators to manually peel off the sticky silicone sheet after cutting, which greatly reduces production efficiency. To address the above problems, the inventors propose a silicone sheet fixed-length cutting device to solve these issues. Utility Model Content

[0003] To address the issues of silicone sheet displacement caused by the cutting blade during the cutting process, which affects subsequent cutting accuracy and quality, and the tendency for cut silicone sheets to adhere tightly due to surface stickiness and static electricity generated during cutting, requiring operators to manually peel off the adhered silicone sheets after cutting, this invention aims to provide a silicone sheet fixed-length cutting device.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Example: Figure 1-4As shown, this utility model provides a technical solution: a silicone sheet fixed-length cutting device, including a base 1, a placement plate 3 fixedly connected to the center of the top of the base 1, a placement groove 31 opened at the center of the top of the placement plate 3, a load-bearing box 23 above the placement plate 3, a moving groove symmetrically opened near the center of the bottom of the load-bearing box 23, a moving block 27 slidably connected inside the moving groove, a top plate 4 fixedly connected to the bottom of the moving block 27, a cutting blade body 42 fixedly connected to the center of the bottom of the top plate 4, and two sets of high-pressure air nozzles 41 symmetrically arranged near the center of the bottom of the top plate 4. A long plate 32 is symmetrically fixedly connected to the top of the two sides near the center. A sliding seat 33 is symmetrically slidably connected to the opposite ends of the two long plates 32.

A pressure plate 37 is symmetrically slidably inserted into the opposite ends of the two square plates 36, and the pressure plate 37 is adapted to the placement groove 31. A scale plate (not shown) can be set at the front end of the load-bearing box 23 according to actual usage requirements to clearly define the distance between the two cutting blade bodies 42. A rotating handle is set at the front end of the load-bearing box 23 to drive the worm gear 26 to rotate. The top of the square plate 36 is near the center of the two sides. A first insertion hole is provided near one side, and an insertion plate is provided on the side end of the pressure plate 37 for insertion into the insertion slot opened on the side end of the square plate 36. The insertion plate has several second insertion holes that match the first insertion hole, which facilitates the positioning of the pressure plate 37 through the insertion shaft. The high-pressure air nozzle 41 is installed at an angle, and the specific angle needs to be determined according to the actual use requirements. In addition, the high-pressure air nozzle 41 needs to work with an air tank and a solenoid valve. When the working solenoid valve is activated, the high-pressure gas is sprayed through the high-pressure air nozzle 41 onto the cut area of ​​the silicone sheet. A guide groove is provided at the center of the side end of the long plate 32. The sliding seat 33 is used for lifting and lowering. A guide groove is provided at the center of the side end of the sliding seat 33 for the second U-shaped seat 34 to lift and lower. This solution aims to protect the physical structure, but does not protect the circuit and software control. The proposed processing circuit is only to supplement the explanation of the feasibility and authenticity of this utility model. This utility model does not require protection of the algorithm and circuit technology. It is worth emphasizing that although the electronic control program is not described in detail in this solution, those skilled in the art can be familiar with and apply it based on their professional knowledge.

[0018] Support rods 11 are fixedly connected to the top of the base 1 near the corners, and a top plate 2 is fixedly connected between the tops of the two sets of support rods 11.

[0019] By adopting the above technical solution, two sets of support rods 11 are set up to support and fix the top plate 2 and slide the load-bearing plate 22.

[0020] A load-bearing plate 22 is slidably connected between the two sets of support rods 11, and the bottom end of the load-bearing plate 22 is fixedly connected to the load-bearing box 23.

[0021] By adopting the above technical solution, the load-bearing plate 22 is slidably set between the two sets of support rods 11 in order to facilitate the lifting and lowering of the load-bearing box 23.

[0022] An electric cylinder 21 is installed at the center of the top of the top plate 2, and the output end of the electric cylinder 21 passes through the top plate 2 and is fixedly connected to the load-bearing plate 22.

[0023] By adopting the above technical solution, the working electric cylinder 21 is activated, thereby causing the fixedly connected load-bearing plate 22 to rise and fall under the action of the two sets of support rods 11.

[0024] A double-ended screw 24 is rotatably connected between the inner walls of both sides of the load-bearing box 23. A worm gear 25 is fixedly connected to the center of the outer ring of the double-ended screw 24. A worm 26 is rotatably connected to the inner walls of the front and rear of the load-bearing box 23 and located below the double-ended screw 24. The worm 26 meshes with the worm gear 25.

[0025] By adopting the above technical solution, after the double-headed screw 24 rotates, the threaded rotating connection can cause two moving blocks 27 to move towards each other.

[0026] The bottom of the load-bearing box 23 is symmetrically fixedly connected to the first U-shaped seat 28 near both sides, and the side of the sliding seat 33 is slidably connected to the second U-shaped seat 34.

[0027] By adopting the above technical solution, a first U-shaped seat 28 is set at the bottom of the load-bearing box 23 and a second U-shaped seat 34 is set at the side of the sliding seat 33 in order to drive the sliding seat 33 to rise and fall.

[0028] A connecting rod 35 is rotatably connected between the second U-shaped seat 34 and the first U-shaped seat 28.

[0029] By adopting the above technical solution, the connecting rod 35 is rotatably connected to the inner wall of the first U-shaped seat 28 and the second U-shaped seat 34, thereby stabilizing the position of the pressure plate 37 when the load-bearing box 23 rises.

[0030] A counterweight 38 is provided at the top of the square plate 36 near the center of one side.

[0031] By adopting the above technical solution, a counterweight 38 is set at the top of the square plate 36 to prevent the load-bearing box 23 from moving the pressure plate 37 when it initially rises.

[0032] Working principle: When using this device, first place the silicone sheet to be cut on the placement groove 31, and then adjust the distance between the two cutting blade bodies 42 according to the required cutting length. During adjustment, the worm 26 is rotated, which causes the meshing worm wheel 25 to drive the double-headed screw 24 to rotate. Then, the two moving blocks 27 connected by the threaded rotation will drive the two cutting blade bodies 42 to move towards each other, thereby adjusting the distance between the two cutting blade bodies 42 to facilitate cutting silicone sheets of different lengths. Next, the electric cylinder 21 is activated, causing the fixedly connected load-bearing plate 22 to drive the two cutting blade bodies 42 to descend. During descent, the connecting rod 35 and the counterweight 38 cause the pressure plate 37 to descend and abut against the silicone sheet, thereby achieving a limiting effect on the silicone sheet and preventing positional movement during cutting, which would affect cutting accuracy. While the cutting blade body 42 rises after cutting, the high-pressure air nozzle 41 is activated (it needs to be used in conjunction with an air tank and a solenoid valve, and its working principle is familiar to those skilled in the art based on their professional knowledge and can be applied, so it will not be described in detail here). This allows the finished product to be separated from the cutting blade body 42, preventing material from sticking.

[0033] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
