Description

Technical Field

[0001] This utility model relates to the field of Teflon high-temperature fabric technology, and in particular to a cutting device for Teflon high-temperature fabric. Background Technology

[0002] Teflon high-temperature fabric is a composite material made of high-performance glass fiber as the base material and coated with polytetrafluoroethylene (PTFE). This material is widely used in numerous fields such as thermoforming, heat transfer printing, printed circuit board manufacturing, food processing conveyor belts, packaging machinery, and drying equipment. It plays an irreplaceable role as a key component, serving as an anti-sticking layer, conveyor belt cover, and thermal insulation material. In practical applications, to meet the needs of different equipment structures and processes, Teflon high-temperature fabric is usually cut to specific lengths.

[0003] A Chinese patent with publication number CN215856888U discloses a cutting device for producing high-temperature Teflon fabric, including a base, a pressure plate, a lower magnet, a lower cotton fabric layer, an upper magnet, and an upper cotton fabric layer. This device has a simple structure and novel design, facilitating the fixing of the high-temperature Teflon fabric and preventing it from tilting or sliding during the cutting process, which would affect the cut dimensions. It facilitates both horizontal and vertical cutting of the high-temperature Teflon fabric, is easy to use and operate, thereby improving cutting efficiency. This device is suitable for widespread application.

[0004] Regarding the above and existing related technologies, the inventors believe that the following defects often exist: magnetic attraction relies on the attraction between the upper and lower magnets, but if a thicker or multi-layered Teflon high-temperature cloth is sandwiched between the upper and lower magnets, the magnetic attraction may be weakened, resulting in an unstable fixation. Utility Model Content

[0005] The technical problem to be solved by this utility model is that the existing technology relies on the attraction between the upper and lower magnets to fix the high-temperature Teflon cloth. When fixing multiple layers or thick high-temperature cloth, it is easy to not fix it firmly. To this end, we propose a cutting device for high-temperature Teflon cloth.

[0006] To achieve the above objectives, this application adopts the following technical solution: a cutting device for Teflon high-temperature cloth, comprising: a workbench, and a support leg fixedly connected to the bottom of the workbench, a cutting blade being provided above the workbench, and a fixing component being provided at the top of the workbench.

[0007] The fixing component includes a fixing block, a rotating shaft rotatably connected to the top of the fixing block, a pressing block fixedly connected to the outer surface of the rotating shaft, a damping spring fixedly connected between the pressing block and the fixing block, and a pressure plate fixedly connected to one side of the pressing block, with the bottom end of the pressure plate in contact with the top of the worktable.

[0008] Preferably, a rubber pad is fixedly connected to the bottom end of the pressure plate, and the rubber pad is a component made of rubber material.

[0009] Preferably, a first slide groove is provided at the top of the worktable, and a power assembly is provided inside the first slide groove. The power assembly includes a dual-head motor, a first rotating rod fixedly connected to the output end of the dual-head motor, a first bevel gear fixedly connected to the outer surface of the first rotating rod, a second bevel gear meshing with one side of the first bevel gear, a second rotating rod fixedly connected inside the second bevel gear, and a bidirectional threaded rod fixedly connected to one end of the second rotating rod. A first slider is threadedly connected to the outer surface of the bidirectional threaded rod. The first slider is fixedly connected to a fixed block. The bidirectional threaded rod is rotatably connected to the inner wall of the first slide groove. The first slider is disposed inside the first slide groove.

[0010] Preferably, a power box is fixedly connected to one side of the workbench, a cover is movably connected to the top of the power box, a double-headed motor is fixedly connected to the inner wall of the power box, the second rotating rod rotates through the power box and the first sliding groove, and the first bevel gear and the second bevel gear are both located inside the power box.

[0011] Preferably, a support frame is fixedly connected to the top of the workbench, a top plate is fixedly connected to one side of the support frame, an electric push rod is provided below the top plate, a mounting plate is fixedly connected to the telescopic end of the electric push rod, a first motor is installed at the top of the mounting plate, and the cutting blade is fixedly connected to the output end of the first motor.

[0014] The technical effects and advantages of this utility model are as follows:

[0015] The main innovation of this invention lies in its simple working principle. Pressing the pressing block separates the pressure plate from the worktable. After placing the fabric in, releasing the block causes the pressure plate to adhere tightly to the worktable under the action of the damping spring, ensuring stable pressure on the fabric and preventing it from slipping or shifting during cutting. This reduces the need for manual support of the fabric and lowers the safety risks for operators. After cutting, pressing the pressing block again removes the fabric. The damping spring automatically adjusts the pressing force according to the fabric thickness, making it suitable for various specifications of Teflon high-temperature fabric. This enhances the versatility of the device and solves the problem in existing technologies where fixing Teflon high-temperature fabric relies on the attraction between the upper and lower magnets, leading to insecure fixing when fixing multiple layers or thicker high-temperature fabrics.

Therefore, the following detailed embodiments and accompanying drawings are merely illustrative descriptions of the technical solution of this utility model and should not be considered as the entirety of this utility model or as limitations or restrictions on the technical solution of this utility model.

[0024] Reference Figure 1 As shown, this utility model provides a technical solution: a cutting device for Teflon high-temperature cloth, including: a workbench 1, and a support leg 11 fixedly connected to the bottom of the workbench 1, a cutting blade 3 is provided above the workbench 1, and a fixing component 2 is provided at the top of the workbench 1.

[0025] Reference Figures 1-5 As shown in this embodiment: the fixing component 2 includes a fixing block 21, a rotating shaft 22 rotatably connected to the top of the fixing block 21, a pressing block 23 fixedly connected to the outer surface of the rotating shaft 22, a damping spring 24 fixedly connected between the pressing block 23 and the fixing block 21, and a pressure plate 25 fixedly connected to one side of the pressing block 23, with the bottom end of the pressure plate 25 in contact with the top of the worktable 1. The pressing block 23 is the operating part. The state of the pressure plate 25 is controlled by manually pressing it down. The damping spring 24 provides rebound force and buffering effect to ensure that the pressure plate 25 can stably adhere to the worktable 1. The pressure plate 25 directly contacts the fabric and applies pressure. Pressing the pressing block 23 can separate the pressure plate 25 from the worktable 1. After the fabric is placed in, the pressing block 23 is released. Under the action of the damping spring 24, the pressure plate 25 adheres tightly to the worktable 1, which facilitates stable pressing of the fabric and prevents the fabric from sliding or shifting during the cutting process. This reduces the need for manual support of the fabric and lowers the safety risk for the operator. After cutting, the pressing block 23 is pressed down again to remove the fabric. The damping spring 24 can automatically adjust the pressing force according to the fabric thickness and is suitable for various specifications of Teflon high-temperature fabric, enhancing the versatility of the device.

[0026] A rubber pad 251 is fixedly connected to the bottom end of the pressure plate 25. The rubber pad 251 is a component made of rubber. Rubber has good friction properties, which can increase the friction between the pressure plate 25 and the fabric. At the same time, the rubber pad 251 has a certain degree of softness, so as not to damage the surface of the fabric while pressing it tightly, thus maintaining the integrity and aesthetics of the fabric.

[0032] Working principle: The dual-head motor 41 drives the first rotating rod 42 and the first bevel gear 43 to rotate. The rotation of the first bevel gear 43 drives the second bevel gear 44 and the second rotating rod 45 to rotate. The rotation of the second rotating rod 45 drives the bidirectional threaded rod 46 to rotate. The bidirectional threaded rod 46 drives the two sets of first sliders 5 to move in opposite directions or towards each other, so that the fixing component 2 can precisely adjust the spacing according to the width of the fabric. Pressing the pressing block 23 separates the pressure plate 25 from the worktable 1. After the fabric is placed in, it is released.
