The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments.

[0037] Teflon tape is expensive, and frequent replacement will increase the cost. In order to reduce the manufacturing cost of the product, two Teflon tapes with the same texture, width and thickness can be cut off by defective parts, and the Teflon tapes without appearance and performance problems can be spliced.

Once there is a slight deviation in the operation, the teeth need to be opened again, which increases the workload and processing costs.

[0039] Combine the following Figure 1-Figure 5 The embodiments of the present utility model are further described.

[0040] In order to solve the above technical problems, the utility model provides a Teflon belt toothing tooling, and a cutting mold is arranged on an operating table. When working, the Teflon belt is pressed into the cutting mold by a pressing mold assembly, so that the position and size accuracy of the Teflon belt toothing can be ensured. Compared with manual knocking, the force and position can be better controlled to avoid uneven tooth opening or misalignment problems, accurately control the cutting position and depth, improve the tooth opening accuracy and tooth opening quality, and a clamping assembly is arranged on the fixed frame, which is responsible for fixing and pressing the Teflon belt that needs to be toothed, ensuring the stability and accuracy of the cutting process, avoiding the problem of poor tooth opening caused by the movement or misalignment of the Teflon belt, ensuring the uniformity of the tooth marks, avoiding burrs on the newly opened tooth surface, and improving the uniformity and consistency of the tooth opening, thereby improving the splicing quality, reducing the waste and loss generated in the cutting process, saving material costs, and improving production efficiency.

[0041] An exemplary embodiment of the present disclosure provides a Teflon belt toothed tooling, referring to Figure 1 and Figure 4 , including a frame, the frame including an operating table 1 and a fixing frame 2 extending in the same direction. For example, referring to Figure 1 The operating table 1 is in a rectangular parallelepiped shape, and the fixing frame 2 includes a crossbeam 201. A connecting beam 202 is vertically arranged at both ends of the crossbeam 201, and the lower end of the connecting beam 202 is connected to the upper surface of the operating table 1. A cutting mold 4 is arranged on the operating table 1, and the cutting mold 4 is arranged along the extension direction of the operating table 1.

[0042] A plurality of clamping assemblies 3 are arranged along the extension direction of the fixing frame 2, and the clamping assemblies 3 cooperate with the operating table 1 to clamp and fix the Teflon belt. A die assembly 5 is arranged on the side of the fixing frame 2 opposite to the operating table 1. Exemplarily, a plurality of clamping assemblies 3 are arranged at intervals on the side wall of the crossbeam 201, and the die assembly 5 is arranged on the lower bottom surface of the crossbeam 201, and the die assembly 5 is arranged opposite to the cutting die 4. In this way, the plurality of clamping assemblies 3 arranged along the extension direction of the fixing frame 2 can cooperate with the operating table 1 to firmly clamp and fix the Teflon belt, and can adapt to Teflon belts of different lengths, thereby increasing the applicability and flexibility of the equipment.

[0043] The die assembly 5 can switch between a storage position and a working position. In the storage position, there is a predetermined distance between the die assembly 5 and the cutting mold 4, and the predetermined distance is greater than the thickness of the Teflon tape. In the working position, the lower end of the die assembly 5 abuts against the cutting mold 4, and the die assembly 5 can slide along the extension direction of the fixed frame 2 so that the die assembly 5 presses the Teflon tape into the cutting mold 4 to cut the teeth of the Teflon tape. In this way, a cutting mold 4 is arranged on the operating table 1. When working, the Teflon belt is pressed into the cutting mold 4 through the pressing mold assembly 5, which can ensure the accuracy of the position and size of the teeth of the Teflon belt. Compared with manual knocking, the force and position can be better controlled to avoid uneven or misaligned teeth, accurately control the cutting position and depth, improve the tooth opening accuracy and tooth opening quality, and a clamping assembly 3 is arranged on the fixed frame 2, which is responsible for fixing and pressing the Teflon belt that needs to be teethed, ensuring the stability and accuracy of the cutting process, avoiding poor tooth opening caused by movement or misalignment of the Teflon belt, ensuring the uniformity of the tooth marks, avoiding burrs on the newly opened tooth surface, and improving the uniformity and consistency of the teeth, thereby improving the splicing quality, reducing the waste and loss generated in the cutting process, saving material costs, and improving production efficiency.

[0044] In some embodiments of the present invention, referring to Figure 1 and Figure 2 The cutting die 4 includes a tooth die, which includes a plurality of cutting teeth 401 connected in sequence, a cutting groove 402 is formed between two adjacent cutting teeth 401, and the notches of the two adjacent cutting grooves 402 are in opposite directions, the direction of the groove bottom of the cutting groove 402 toward the notch of the cutting groove 402 is the first direction, and the width of the cutting groove 402 increases first, then decreases, and then increases again along the first direction, and the tooth die cooperates with the die assembly 5 to cut the Teflon belt. Among them, the material of the cutting teeth 401 can be cemented carbide or stainless steel. The cutting teeth 401 made of cemented carbide or stainless steel are durable, have good cutting effect, and have smooth and smooth incisions. By opening the Teflon belt through the tooth die, the tooth shape of the opening can be wavy, which can increase the contact area during splicing, thereby enhancing the strength of the splicing, and further improving the firmness and stability of the splicing.

[0045] In some embodiments of the present invention, referring to Figure 1 and Figure 2 Two fixed plates 101 are also arranged in parallel on the operating table 1. There is a predetermined gap between the two fixed plates 101. The tooth mold is installed in the predetermined gap. The upper end of the tooth mold is in the same plane as the upper surface of the fixed plate 101. The clamping assembly 3 cooperates with the fixed plate 101 to clamp and fix the Teflon tape. By installing the tooth mold in the predetermined gap between the two fixed plates 101, a precise installation position is provided for the tooth mold, ensuring the stability and position accuracy of the tooth mold. At the same time, the clamping assembly 3 cooperates with the fixed plate 101 to firmly clamp the Teflon tape, so that it maintains a stable position during the cutting process, avoiding movement or dislocation, thereby ensuring the accuracy and quality of cutting. Since the upper end of the tooth mold is flush with the fixed plate 101, when the die assembly 5 is pressed down, the Teflon tape will be evenly pressed onto the tooth mold, and the force is evenly applied, forming a cutting effect with a uniform pressing force. This design reduces the error in the cutting process and improves the accuracy and consistency of cutting.

[0046] In some embodiments of the present invention, referring to Figure 1 , Figure 4 and Figure 5The die assembly 5 includes a slider 501, a support frame 502 and a rolling wheel 503; a slide rail 504 is provided on the side of the fixed frame 2 opposite to the operating table 1, and a slide groove matching the slide rail 504 is provided on the upper surface of the slider 501, and the slide groove is slidably connected with the slide rail 504. For example, two parallel slide rails 504 are provided on the lower surface of the crossbeam 201 of the fixed frame 2, and a slide groove matching the slide rail 504 is provided on the upper surface of the slider 501. The slide rail 504 is installed in the slide groove, and the slider 501 can slide along the slide rail 504. At least one spring 505 is provided between the lower surface of the slider 501 and the support frame 502, and the rolling wheel 503 is rotatably connected to the lower end of the support frame 502; in the storage position, the spring 505 is contracted, and a predetermined distance is generated between the die assembly 5 and the cutting die 4. In the working position, the spring 505 is stretched, and the lower end of the die assembly 5 abuts against the cutting die 4. Exemplarily, one end of the spring 505 is connected to one of the end faces of the slider 501 close to the connecting beam 202, and the other end of the spring 505 is connected to the lower surface of the slider 501. A mounting hole is provided at the lower end of the support frame 502, and a rotating shaft is provided on both sides of the rolling wheel 503, and the rotating shaft is installed in the mounting hole, so as to realize the rotation of the rolling wheel 503. In this way, through the sliding connection between the slide groove and the slide rail 504, the die assembly 5 can be flexibly moved on the operating table 1. When cutting is required, the die assembly 5 is quickly moved from the storage position to the working position, and the Teflon belt is vertically pressed into the tooth mold to ensure uniform force, making the operation more convenient and improving work efficiency. In the storage position, the spring 505 contracts so that the upper surface of the support frame 502 fits the lower surface of the slider 501, and the support frame 502 drives the rolling wheel 503 to generate a predetermined distance between the tooth mold, avoiding unnecessary pressure or damage to the cutting mold 4 or the rolling wheel 503 when not working, thereby improving work safety.

[0047] In some embodiments of the present invention, referring to Figure 1 , Figure 4 and Figure 5 A push handle 506 is provided on one side of the support frame 502 away from the clamping assembly 3. In this way, the staff can easily move the die assembly 5 through the push handle 506. Through the push handle 506, the staff can more accurately control the moving speed and position of the die assembly 5, which greatly simplifies the operation process and improves work efficiency.

[0048] In some embodiments of the present invention, referring to Figure 1 and Figure 4, the width of the rolling wheel 503 is greater than the width of the predetermined gap between the two fixing plates 101. Thus, when the rolling wheel 503 is pressed down, since its width is greater than the gap between the fixing plates 101, it can ensure that the rolling wheel 503 and the Teflon belt are in full contact, which helps to evenly apply pressure, improve the accuracy and consistency of tooth opening, and thus reduce material waste caused by incomplete cutting or uneven edges.

[0049] In some embodiments of the present invention, referring to Figure 1 and Figure 3 The clamping assembly 3 includes a pressing plate 301 and a push-pull clamp, the push-pull clamp is fixed on the side wall of the fixing frame 2, the lower end of the push-pull clamp is fixedly connected to the pressing plate 301, and the push-pull clamp can drive the pressing plate 301 to move along the height direction of the fixing frame 2. In this way, the distance between the pressing plate 301 and the fixing plate 101 is adjusted by the push-pull clamp, and the position of the pressing plate 301 is flexibly adjusted to meet the cutting requirements of Teflon tapes of different thicknesses, which can cope with more production scenarios and requirements.

[0050] In some embodiments of the present invention, referring to Figure 1 and Figure 3 The push-pull clamp includes a mounting plate 302, a handle 303, a push-pull rod 304 and a connecting rod 305. The mounting plate 302 is fixedly mounted on the fixing frame 2. A column sleeve 306 is installed at the lower end of the mounting plate 302. The lower end of the push-pull rod 304 passes through the column sleeve 306 and is fixedly connected to the pressure plate 301; the first end of the handle 303 is hinged to the upper end of the mounting plate 302 through a first hinge, the upper end of the connecting rod 305 is hinged to the first end of the handle 303 through a second hinge, and the lower end of the connecting rod 305 is hinged to the upper end of the push-pull rod 304 through a third hinge. When in use, lift the handle 303 upward. As the handle 303 moves upward, the handle 303 and the mounting plate 302 rotate relative to each other through the action of the first hinge. At this time, the connecting rod 305 will also move with the upward movement of the handle 303. The handle 303 and the connecting rod 305 rotate through the second hinge. The lower end of the connecting rod 305 is connected to the upper end of the push-pull rod 304 through the third hinge. Therefore, the movement of the connecting rod 305 will drive the push-pull rod 304 to move upward. During the upward movement of the push-pull rod 304, its lower end will drive the pressing plate 301 to move upward, thereby separating the pressing plate 301 from the operating table 1, placing the Teflon belt between the pressing plate 301 and the operating table 1, pressing the handle 303 downward, and as the handle 303 moves downward, the push-pull rod 304 will move downward through the transmission action of the first hinge, the second hinge and the third hinge, thereby clamping the Teflon belt. Here, the column sleeve 306 provides a stable guiding function for the push-pull rod 304, ensuring that the push-pull rod 304 can move up and down along a predetermined trajectory. At the same time, the use of the hinge also ensures the stability and reliability of the entire clamp structure.

[0051] In some embodiments of the present invention, referring to Figure 1 and Figure 3 At least one of the first hinge, the second hinge and the third hinge is a damping hinge. The damping hinge can provide a stable damping force when the push-pull clamp is closed, and the damping force can prevent the pressure plate 301 and the fixing plate 101 from loosening due to external force or vibration, thereby ensuring the fixation of the Teflon belt and improving the cutting stability.

[0052] In some embodiments of the present invention, referring to Figure 1 and Figure 4 , a plurality of pulleys 6 are arranged on the lower surface of the operating table 1. For example, four pulleys 6 are arranged on the lower surface of the operating table 1, wherein the pulleys 6 can be universal wheels, and the four pulleys 6 are respectively installed at the four corners of the lower surface of the operating table 1. In this way, the pulleys 6 can make the Teflon toothed tooling move easily, thereby reducing the wear of the operating table 1 during the movement process, extending the service life of the equipment, and not relying on a large amount of manpower.
