[0002] Plastic sealing strips have excellent sealing, dustproof, waterproof and cushioning properties, and are widely used in many industries such as automobiles, construction, and electrical appliances. In the production and processing of plastic sealing strips, it is usually necessary to cut long strips into segments of specific lengths according to actual usage requirements.

[0003] In existing technology, the sealing strip is placed on a workbench and fixed in place. After it is fixed, the staff will measure the length of the sealing strip and cut it with a utility knife.

[0004] However, in actual use, the use of tools such as utility knives and scissors for cutting is not only labor-intensive and inefficient, but also prone to burrs and skewing due to improper operation, which affects the subsequent quality of the plastic sealing strip. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a plastic sealing strip cutting device, which solves the problem that in actual use, personnel use tools such as utility knives and scissors to cut the strips. This method is not only labor-intensive and inefficient, but also prone to producing burrs and skewing due to improper operation, thus affecting the subsequent quality of the plastic sealing strips.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a plastic sealing strip cutting device, comprising a straight plate, a placement platform fixedly connected to the top of the straight plate, a cutter disposed above the placement platform, a bracket mounted on the outer wall of the cutter, the bottom of the bracket movably connected to the top of the straight plate, fixed blocks movably connected to both sides of the top of the placement platform, and a limit component mounted on the outer wall of the cutter.

[0014] Beneficial effects

[0015] This utility model provides a plastic sealing strip cutting device. It has the following advantages: The device uses a fixing block, a limiting component, and a cutter to fix the rubber strip on a placement table. The fixing block then cuts the sealing strip on the table using the cutter. The limiting component ensures that the cutter cuts the rubber strip perpendicularly, resulting in a smoother cross-section. This solves the problem of manual cutting with tools like utility knives and scissors, which is not only labor-intensive and inefficient but also prone to burrs and misalignment due to improper operation, affecting the subsequent quality of the plastic sealing strip.

[0016] By using the cooperation of the slide, slider, and bracket, when different lengths of sealing strips need to be cut, the slider at the bottom of the bracket is pushed to move in the slide groove at the top of the straight plate. This allows the position of the cutter to be adjusted, enabling workers to cut sealing strips of different lengths at will, thus solving the problem of inconvenience in cutting sealing strips of different lengths in existing technologies.

[0022] 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.

[0023] In actual use, the cutting is done by people using tools such as utility knives and scissors. This method is not only labor-intensive and inefficient, but also prone to burrs and crooked cuts due to improper operation, which affects the quality of the plastic sealing strip in subsequent use.

[0024] In view of this, the present invention provides a plastic sealing strip cutting device, which solves the problem that in actual use, when people use tools such as utility knives and scissors to cut the plastic sealing strip, this method is not only labor-intensive and inefficient, but also prone to burrs and skewing due to improper operation, which affects the subsequent use quality of the plastic sealing strip.

[0025] Those skilled in the art can connect the components in this case sequentially. The specific connection and operation sequence should refer to the working principle described below. The detailed connection methods are well-known technologies in the field. The following mainly introduces the working principle and process.

[0026] Example 1: By Figure 1-4 It is known that a plastic sealing strip cutting device includes a straight plate 1, a placement platform 2 is fixedly connected to the top of the straight plate 1, a cutter 4 is provided above the placement platform 2, a bracket 5 is installed on the outer wall of the cutter 4, the bottom of the bracket 5 is movably connected to the top of the straight plate 1, a fixing block 3 is movably connected to both sides of the top of the placement platform 2, and a limit component is installed on the outer wall of the cutter 4.

[0027] In the specific implementation process, it is worth noting that the size and shape of the cutter 4 should be the same as the shape of the sealing strip, and the size of the placement platform 2 should also be similar to the size of the sealing strip. This ensures stability when the cutter 4 cuts the sealing strip. The shapes of the placement platform 2 and the cutter 4 in the attached diagram are for reference only; the specific shapes should be determined according to the actual situation. At least ensure that the bottom of the cutter 4 and the top of the placement platform 2 fit together to thoroughly cut the sealing strip. The straight plate 1 serves as the main support device, ensuring stability during operation. A scale should be provided on the top of the straight plate 1 for easy measurement of the cut length of the sealing strip. The sealing strip on the placement platform 2 is fixed by the fixing block 3. To ensure stability during cutting, a gap is reserved between the bottom of the fixing block 3 and the placement platform 2 to clamp the sealing strip. This allows a sealing strip to be split in two at a designated position in the middle. Of course, when cutting a sealing strip into multiple segments, only one fixing block 3 can be installed to limit one end of the sealing strip. The end of the sealing strip is attached to the surface of the fixing block 3, which helps to determine the zero mark of the sealing strip. The cutting length of the sealing strip is confirmed by referring to the scale on the surface of the straight plate 1 before cutting. At the same time, when the cutter 4 cuts the sealing strip, the limiting component can ensure that the cutter moves vertically downward, which can ensure that the cross-section of the cut sealing strip is flat and avoid affecting the quality of the product.

[0028] Furthermore, the limiting component includes a fixed frame 8, which is fixedly connected to the outer wall of the bracket 5. A limiting groove 14 is provided on the inner wall of the fixed frame 8. The limiting groove 14 is sleeved on the outer wall of the cutter 4. A pressure plate 7 is fixedly connected to the top of the cutter 4. A spring 15 is pressed between the pressure plate 7 and the fixed frame 8.

[0029] In the specific implementation process, it is worth noting that the shape of the limiting groove 14 is similar to that of the cutter 4. When the cutter 4 moves downward under the drive of the pressure plate 7, the cutter 4 will move stably inside the limiting groove 14, ensuring that the cutter 4 cuts the sealing strip more smoothly and avoids burrs and skewing. Moreover, after the cutting is completed, after the operator releases the pressure plate 7, the pressure plate 7 will drive the cutter 4 to return to its original position under the compression of the spring 15, making it more stable in subsequent processing.

[0030] Furthermore, a rod 12 is inserted into the inner wall of the spring 15, and a rubber sleeve 16 is fitted onto the upper part of the outer wall of the rod 12. One end of the rod 12 that passes through the rubber sleeve 16 is fixedly connected to a limiting block 13. The outer wall of the rubber sleeve 16 is fixedly connected to the inner wall of the pressure plate 7. One end of the rod 12 that passes through the fixing frame 8 is fixedly connected to a limiting frame 9. A rubber pad 11 is fixedly connected to the bottom of the limiting frame 9. A fixing groove 17 is opened on the inner wall of the limiting frame 9. The fixing groove 17 is fitted onto the lower part of the outer wall of the cutter 4.

[0031] In the specific implementation process, it is worth noting that the insert rod 12 is inserted into the inner wall of the spring 15. This ensures that the spring 15 moves up and down when compressed, preventing displacement. Moreover, the insert rod 12 is connected to the inner wall of the fixed frame 8 through the rubber sleeve 16. The rubber sleeve 16 is made of rubber, which increases the friction between the insert rod 12 and the rubber sleeve 16. When the pressure plate 7 moves downward, it will drive the insert rod 12 and the limiting frame 9 to move downward together, and stop after the rubber pad 11 at the bottom of the limiting frame 9 presses against the sealing strip. To prevent movement, since the pressure plate 7 and the cutter 4 have not yet cut the sealing strip, the insert rod 12 will move upward from the rubber sleeve 16 to avoid affecting the downward movement of the pressure plate 7. After the cutter 4 cuts the sealing strip, the spring 15 will return the pressure plate 7 to its original position after the operator presses the pressure plate 7. Under the pressure of the pressure plate 7, the limit block 13 will drive the insert rod 12 and the limit frame 9 back to their original positions, so that they can work repeatedly in subsequent processing. Under the pressure of the limit frame 9 and the rubber pad 11, the sealing strip will be stable during cutting.

[0032] Example 2: From Figure 1-4 It can be seen that the top of the straight plate 1 is provided with a groove 6, and the inner wall of the groove 6 is slidably engaged with a slider 10, and the top of the slider 10 is fixedly connected to the bottom of the bracket 5.

[0033] In the specific implementation process, it is worth noting that both the slide groove 6 and the slider 10 are trapezoidal, so that the slider 10 is stable when sliding in the slide groove 6, thereby making the support 5 drive the cutter 4 to cut the sealing strip stably. At the same time, the support 5 can be fixed to the top of the straight plate 1 with bolts, so that the cutter 4 is stable when cutting the sealing strip.

[0034] Furthermore, fixing brackets 18 are fixedly connected to both sides of the outer wall of the two fixing blocks 3, and the bottom of the fixing brackets 18 is fixedly connected to the top of the straight plate 1 by bolts.

[0035] In the specific implementation process, it is worth noting that when cutting sealing strips of different lengths, pushing the fixing bracket 18 to move on the top of the straight plate 1 and moving the fixing block 3 on the placement platform 2 can effectively fix sealing strips of different lengths. In addition, several holes are opened at equal intervals on the top of the straight plate 1, which makes it convenient to adjust the position of the fixing block 3.

[0036] 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.
