Description

Technical Field

[0001] This utility model relates to the field of sealing strip cutting technology, and in particular to a sealing strip cutting device. Background Technology

[0002] A sealing strip cutting device is a specialized piece of equipment used for cutting and processing sealing strips. Sealing strips are widely used in industries such as doors and windows, automobiles, construction, and home appliances to provide functions such as sealing, waterproofing, and dustproofing. In order to meet the needs of different sizes and shapes, sealing strips need to be precisely cut during the processing, and this device is designed for this purpose.

[0003] The existing 45-degree chamfer design requires two separate cuts on both the front and back sides. This not only increases the number of steps but also reduces cutting efficiency, increases operation time, and impacts overall production efficiency. Furthermore, the two-stage cutting may introduce the risk of asymmetrical cutting, further affecting product precision.

[0004] Therefore, the existing 45-degree angle cutting design requires two separate cuts on both the front and back sides. This not only increases the number of operation steps but also reduces cutting efficiency and lengthens the operation time, affecting overall production efficiency. Furthermore, the two-stage cutting may lead to the risk of asymmetrical cutting, further affecting product precision. A sealing strip cutting device can be designed. Through design improvements, a 45-degree angle cut can be completed in one go, reducing operation steps and greatly improving cutting efficiency. After the improvement, the equipment can simultaneously and accurately cut both sides, ensuring the consistency of the cutting angle, reducing manual intervention, increasing production speed, and simultaneously improving cutting precision and product quality. Utility Model Content

[0005] To overcome the limitations of the existing 45-degree chamfer design, which requires cutting twice on both the front and back sides, this not only increases the number of steps but also reduces cutting efficiency and increases operation time, affecting overall production efficiency. In addition, cutting twice may lead to the risk of asymmetrical cutting, further affecting the precision of the product.

[0006] The technical solution of this utility model is as follows: a sealing strip cutting device, including a main body and a cutting assembly. The cutting assembly is provided at the right end of the main body. The cutting assembly includes a connecting plate, a sliding frame, a spring, a sliding block, a roller, a piston, a blade, a lifting frame, a motor, a lead screw, a lifting plate, and a lever. The right end of the main body is connected to the connecting plate, which is L-shaped. Two sliding frames are symmetrically arranged at the left end of the connecting plate along its vertical center line. Springs are connected inside the two sliding frames. Sliding blocks are slidably connected inside the sliding frames. Rollers are rotatably connected to the top of the sliding blocks. There are two rollers. The sliding blocks are connected to the springs. A piston is connected to the top of the sliding blocks. A blade is connected to the left end of the piston. The blade is inclined. The top of the connecting plate is connected to the lifting frame. A motor is connected to the top of the lifting frame. The output end of the motor extends into the interior of the lifting frame and is connected to a lead screw. The lead screw is rotatably connected to the lifting frame. The outer end of the lead screw is threadedly connected to the lifting plate. The lifting plate is slidably connected to the lifting frame. A lever is connected to the bottom of the lifting plate and is movably connected to the roller.

[0007] Preferably, by setting up a cutting assembly, starting the motor, the motor drives the lead screw to rotate, and the rotation of the lead screw causes the lifting plate to move vertically within the lifting frame. The movement of the lifting plate causes the push block to press down, thereby squeezing the roller. The roller is squeezed by external force, causing the sliding block to slide within the sliding frame, thereby squeezing the spring and causing the spring to contract. The piston quickly drives the blade plate to move, achieving the effect of cutting both the front and back sides of the rubber strip simultaneously. The push block rises, and the spring helps the sliding block return to its original position, thus completing the cutting. This solves the problem that the existing 45-degree cutting angle design requires cutting the front and back sides twice, which not only increases the number of operation steps but also leads to a decrease in cutting efficiency and a longer operation time, affecting the overall production efficiency. In addition, cutting twice may bring the risk of asymmetrical cutting, further affecting the product's precision.

[0008] Preferably, the main body has a through-hole groove, and the main body has inclined grooves on the front and rear sides.

[0009] Preferably, the slant groove and the blade plate are matched, and the outer end of the slant groove is wrapped with a metal frame.

[0010] Preferably, the metal frame is movably connected to the blade, and an auxiliary block is connected to the left end of the main body.

[0011] Preferably, the top of the auxiliary block is connected to a slide rail, and a measuring scale is slidably connected inside the slide rail.

[0012] Preferably, the top of the measuring ruler has graduations at equal intervals, and the front end of the measuring ruler is connected to a baffle corresponding to the material passage.

[0013] Preferably, the main body is made of polymer glass material, and the metal frame is made of stainless steel.

[0014] The beneficial effects of this utility model are:

[0015] 1. By setting up the cutting assembly and starting the motor, the motor drives the lead screw to rotate. The rotation of the lead screw causes the lifting plate to move vertically within the lifting frame. The movement of the lifting plate causes the push block to press down, thereby squeezing the roller. The roller is squeezed by external force, causing the sliding block to slide within the sliding frame, which in turn squeezes the spring, causing the spring to contract. The piston then quickly drives the blade plate to move, achieving the effect of cutting both the front and back sides of the rubber strip simultaneously. The push block rises, and the spring helps the sliding block return to its original position, thus completing the cutting. This solves the problem of the existing 45-degree cutting angle design, which requires cutting the front and back sides twice. This not only increases the number of operation steps but also leads to a decrease in cutting efficiency and a longer operation time, affecting the overall production efficiency. In addition, cutting twice may bring the risk of asymmetrical cutting, further affecting the product's precision. Attached Figure Description

[0021] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0022] Please see Figure 1-Figure 4This utility model provides an embodiment of a sealing strip cutting device, including a main body 1 and a cutting assembly. The cutting assembly is located at the right end of the main body 1. The cutting assembly includes a connecting plate 21, a sliding frame 22, a spring 23, a sliding block 24, a roller 25, a piston 26, a blade 27, a lifting frame 28, a motor 29, a lead screw 210, a lifting plate 211, and a lever 212. The connecting plate 21 is connected to the right end of the main body 1. The connecting plate 21 is L-shaped. Two sliding frames 22 are symmetrically arranged at the left end of the connecting plate 21 along its vertical center line. A spring 23 is connected inside the frame 22. A sliding block 24 is slidably connected inside the sliding frame 22. Two rollers 25 are rotatably connected to the top of the sliding block 24. The sliding block 24 is connected to the spring 23. A piston 26 is connected to the top of the sliding block 24. A blade 27 is connected to the left end of the piston 26. The blade 27 is inclined. A lifting frame 28 is connected to the top of the connecting plate 21. A motor 29 is connected to the top of the lifting frame 28. The output end of the motor 29 extends into the lifting frame 28 and is connected to a lead screw 210. The lead screw 210 is connected to the lifting frame 28. 8. A rotating connection is made, with a lifting plate 211 threadedly connected to the outer end of the lead screw 210. The lifting plate 211 is slidably connected to the lifting frame 28. A lever 212 is connected to the bottom of the lifting plate 211, and the lever 212 is movably connected to the roller 25. By setting the cutting assembly, the motor 29 is started, and the motor 29 drives the lead screw 210 to rotate. The rotation of the lead screw 210 causes the lifting plate 211 to move vertically within the lifting frame 28. The movement of the lifting plate 211 causes the lever 212 to press down, thereby squeezing the roller 25. The roller 25 is squeezed by external force, causing the sliding block 24 to slide within the sliding frame 22. The piston 26 moves, squeezing the spring 23 to compress it. This causes the piston 26 to quickly move the blade 27, achieving simultaneous cutting of both the front and back sides of the rubber strip. The paddle block 212 rises, and the spring 23 helps the sliding block 24 return to its original position, thus completing the cutting. This solves the problem that the existing 45-degree cutting angle design requires cutting the front and back sides twice, which not only increases the number of operation steps but also reduces cutting efficiency and lengthens the operation time, affecting the overall production efficiency. In addition, cutting twice may lead to the risk of asymmetrical cutting, further affecting the precision of the product.

[0023] Please see Figure 1-Figure 4 In this embodiment, a material-passing groove 31 is provided through the interior of the main body 1, and inclined grooves 32 are provided on the front and rear sides of the interior of the main body 1. The material-passing groove 31 is used to pass the rubber strip through, and the inclined grooves 32 are used to assist in cutting. The inclined grooves 32 are matched with the blade plate 27. The outer end of the inclined grooves 32 is wrapped with a metal frame 33. The metal frame 33 is used to protect the inclined grooves 32 and the main body 1 from being damaged by the blade plate 27. The metal frame 33 is movably connected to the blade plate 27. An auxiliary block 34 is connected to the left end of the main body 1. The auxiliary block 34 is used to assist in measuring the required length of the rubber strip.

[0024] Please see Figures 2-4In this embodiment, a slide rail 35 is connected to the top of the auxiliary block 34, and a measuring ruler 36 is slidably connected inside the slide rail 35. The measuring ruler 36 slides on the slide rail 35 to measure the length of the adhesive strip. The top of the measuring ruler 36 has equally spaced scales 37. A baffle 38 is connected to the front end of the measuring ruler 36 corresponding to the position of the material groove 31. The scales 37 are used to check the required length of the adhesive strip, and the baffle 38 is used to restrict the position of the adhesive strip. The main body 1 is made of polymer glass material, and the metal frame 33 is made of stainless steel. Polymer glass combines the advantages of organic glass and glass, and has higher impact resistance and transparency. Although it has high strength, it is lighter and easier to process than traditional glass. The transparency of the main body 1 makes it easy for users to see the situation of the adhesive strip inside the main body 1.

[0025] During operation, the adhesive strip is passed through the feed groove 31, and the baffle 38 is adjusted. The baffle 38 causes the measuring ruler 36 to slide on the slide rail 35. After adjustment to the required size, the adhesive strip is pressed against the baffle 38, and the motor 29 is started. The motor 29 drives the lead screw 210 to rotate. The rotation of the lead screw 210 causes the lifting plate 211 to move vertically within the lifting frame 28. The movement of the lifting plate 211 causes the push block 212 to press down, thereby squeezing the roller 25. The roller 25 is squeezed by external force, causing the sliding block 24 to slide within the sliding frame 22, thereby squeezing the spring 23 and causing the spring 23 to contract. The piston 26 is used to quickly drive the blade 27 to move within the inclined groove 32. The metal frame 33 is used to protect the inclined groove 32 and the main body 1 from damage by the blade 27, achieving the effect of cutting the front and rear sides of the adhesive strip simultaneously. The push block 212 rises, and the spring 23 helps the sliding block 24 to return to its original position, thus completing the cutting.

[0026] Through the above steps, by setting the cutting assembly, starting the motor 29, the motor 29 drives the lead screw 210 to rotate, and the rotation of the lead screw 210 drives the lifting plate 211 to move vertically within the lifting frame 28. The movement of the lifting plate 211 drives the push block 212 to press down, thereby squeezing the roller 25. The roller 25 is squeezed by external force, causing the sliding block 24 to slide within the sliding frame 22, thereby squeezing the spring 23 and causing the spring 23 to contract. The piston 26 is used to quickly drive the blade plate 27 to move, achieving the effect of cutting the front and rear sides of the rubber strip simultaneously. The push block 212 rises, and the spring 23 helps the sliding block 24 to return to its original position, thus completing the cutting. This solves the problem that the existing 45-degree cutting angle design requires cutting the front and rear sides twice, which not only increases the number of operation steps but also leads to a decrease in cutting efficiency and a longer operation time, affecting the overall production efficiency. In addition, cutting twice may bring the risk of cutting asymmetry, further affecting the product's precision.
