Abstract
Description
Technical Field
[0001] This utility model relates to the field of polytetrafluoroethylene (PTFE) plate cutting technology, specifically to a PTFE plate cutting device with adjustable thickness. Background Technology
[0002] Polytetrafluoroethylene (PTFE) sheets (also called PTFE sheets, Teflon sheets, or PTFE plates) are made from PTFE resin through molding at room temperature, followed by sintering and cooling. They are available in both molded and machined varieties. PTFE products have a wide range of applications and possess excellent comprehensive properties: resistance to high and low temperatures (-192℃-260℃), corrosion resistance (strong acids, strong alkalis, aqua regia, etc.), weather resistance, high insulation, high lubricity, non-adhesion, and non-toxicity. PTFE (abbreviated as Teflon or [PTFE, F4]), commonly known as the "King of Plastics," is also known by various Chinese trade names such as "Teflon," "Tefluron," "Tefulong," and "Teflon."
[0003] When conventional PTFE sheets are processed on cutting equipment, the lack of structural support above may cause unnecessary vertical offset during the processing, which affects the quality of the cutting process. Summary of the Invention
[0004] The purpose of this invention is to provide a polytetrafluoroethylene (PTFE) sheet cutting device with adjustable thickness to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution: an adjustable-thickness polytetrafluoroethylene (PTFE) sheet cutting device, comprising a cutting table assembly and a first adjusting frame assembly. Adjusting columns are vertically and movably installed at the four opposite corners of the bottom of the cutting table assembly. The first adjusting frame assembly is horizontally installed above the middle of the cutting table assembly, and a second adjusting frame assembly is horizontally mounted on both the front and rear sides of the cutting table assembly. Limiting plates are connected to the lower left and right ends of the second adjusting frame assembly. The first adjusting frame assembly includes a stabilizing frame, lifting rods, connecting piles, a protective cover, and stabilizing pressure plates. Lifting rods are vertically installed at the left and right ends of the stabilizing frame, and a connecting pile is vertically installed in the middle of the stabilizing frame. A protective cover is connected to the bottom of the connecting pile, and stabilizing pressure plates are horizontally arranged at the bottom of both the left and right sides of the protective cover.
[0006] Furthermore, the cutting table assembly includes a processing table, a circular saw, a barrier cover, and a drive motor. The circular saw is vertically mounted in the middle of the processing table, and a barrier cover is provided in the middle of the bottom of the processing table. A drive motor is provided on one side of the barrier cover.
[0007] Furthermore, the drive motor is installed at the bottom of the processing table with an embedded structure, and the power output end of the drive motor is connected to the center of the circular saw through a coupling. Moreover, the lower end of the circular saw is located inside the barrier cover.
[0008] Furthermore, the adjusting column includes a lifting column, a stabilizing seat, and an anti-slip pad. The bottom of the lifting column is equipped with a stabilizing seat, and the bottom of the stabilizing seat is provided with an anti-slip pad. Moreover, the stabilizing seat has holes at its four opposite corners for bolt installation.
[0009] Furthermore, the lifting rod is used for vertical adjustment of the stabilizer frame, the top middle of the protective cover and the bottom end of the connecting pile are movably connected, and the stabilizing pressure plate and the protective cover are fixedly connected.
[0010] Furthermore, the second adjustment frame assembly includes a crossbeam, guide rails, lead screw, movable seat, buffer rod, docking seat, and servo motor. Guide rails are symmetrically installed on the bottom of the crossbeam, and a lead screw is horizontally mounted directly below the guide rails. A movable seat is connected to the surface of the lead screw, and a buffer rod is horizontally installed at the bottom of the movable seat. At the same time, a docking seat is connected to one end of the buffer rod near the vertical central axis of the crossbeam. Servo motors are installed on both the left and right ends of the crossbeam.
[0011] Furthermore, the guide rail, lead screw, moving seat, buffer rod, docking seat, and servo motor are all symmetrically arranged with the vertical center axis of the cross frame as the central axis, and one end of the lead screw is connected to the power output end of the servo motor through a coupling.
[0012] Furthermore, the end of the docking seat away from the buffer rod is movably connected to one side of the limiting plate, and the movable seat is connected to the guide rail and the lead screw in a slotted embedded structure and a threaded connection, respectively.
[0013] This utility model provides a polytetrafluoroethylene (PTFE) sheet cutting device with adjustable thickness, which has the following beneficial effects:
[0014] 1. This utility model, by setting an adjusting column, allows the barrier cover to be placed over the upper part of the circular saw. Simultaneously, with the extension and retraction of the lifting rods at both ends of the stabilizing frame, a protective cover connected to the middle of the stabilizing frame via connecting piles can achieve lifting and lowering adjustment within a certain range. This structure allows for flexible adjustment to match the thickness specifications of the PTFE sheet being cut. This ensures that the barrier cover protects the normal and stable operation of the circular saw without causing unnecessary structural interference to its rotation. Furthermore, the stabilizing pressure plates at the bottom of both sides of the protective cover move synchronously with the lifting and lowering of the protective cover. This structure provides sufficient structural stability to the top of the PTFE sheet being processed, ensuring that the PTFE sheet does not jump vertically during the cutting process and reducing cutting errors.
[0015] This invention features a second adjusting frame assemblies symmetrically installed at both ends of the cutting table assembly. Limiting plates are connected to the bottom ends of these second adjusting frame assemblies. Under the operation of a servo motor, the lead screw connected to the second adjusting frame assemblies rotates synchronously in the horizontal axis, causing the movable seat connected to the lead screw to move horizontally. This, in turn, pulls the buffer rod connected at the bottom to move along with the lead screw, thereby pulling the limiting plates connected to the docking seat horizontally across the surface of the processing table. This structural design ensures the flexibility of the device's operation and provides left and right limiting guidance for the polytetrafluoroethylene (PTFE) sheet being processed, ensuring the stability of the entire PTFE sheet during the cutting process. Furthermore, the guide rail, lead screw, movable seat, buffer rod, docking seat, and servo motor are all symmetrically arranged with the vertical central axis of the crossbeam as the central axis, allowing the left and right limiting plates to be independently adjusted. This enables adjustments to different positions within a certain range according to the cutting needs of the PTFE sheet, meeting various processing requirements. Attached Figure Description

Detailed Implementation
[0021] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.
[0022] like Figures 1 to 4As shown, an adjustable-thickness polytetrafluoroethylene (PTFE) sheet cutting device includes a cutting table assembly 1 and a first adjusting frame group 3. Adjusting columns 2 are vertically and movably installed at the four diagonal corners of the bottom of the cutting table assembly 1. The first adjusting frame group 3 is horizontally installed above the middle of the cutting table assembly 1, and second adjusting frame groups 4 are horizontally mounted on both the front and rear sides of the cutting table assembly 1. Limiting plates 5 are connected to the lower left and right ends of the second adjusting frame groups 4. The first adjusting frame group 3 includes a stabilizing frame 301, a lifting rod 302, a connecting pile 303, a protective cover 304, and a stabilizing pressure plate 305. The stabilizing frame 301 has lifting rods 302 vertically installed at both ends, and a connecting pile 303 vertically installed in the middle of the stabilizing frame 301. A protective cover 304 is connected to the bottom of the connecting pile 303, and stabilizing pressure plates 305 are horizontally installed on the bottom of both sides of the protective cover 304. The cutting table assembly 1 includes a processing table 101, a circular saw 102, a barrier cover 103, and a drive motor 104. The circular saw 102 is vertically installed in the middle of the processing table 101, and a barrier cover 103 is installed in the middle of the bottom of the processing table 101. A barrier cover 103 is also installed on one side of the barrier cover 103. A drive motor 104 is provided, which is embedded in the bottom of the processing table 101. The power output end of the drive motor 104 is connected to the center of the circular saw 102 via a coupling. The lower end of the circular saw 102 is located inside the barrier cover 103. The adjusting column 2 includes a lifting column 201, a stabilizing seat 202, and an anti-slip pad 203. The stabilizing seat 202 is installed at the bottom of the lifting column 201, and the bottom of the stabilizing seat 202 is provided with an anti-slip pad 203. The stabilizing seat 202 has four openings at its four opposite corners for bolt installation. The perforated structure allows for vertical adjustment of the stabilizing frame 301 via lifting rods 302. A movable connection exists between the top center of the protective cover 304 and the bottom end of the connecting pile 303. Furthermore, a fixed connection exists between the stabilizing pressure plate 305 and the protective cover 304. With the expansion and contraction of the lifting rods 302 at both ends of the stabilizing frame 301, the protective cover 304, connected to the middle of the stabilizing frame 301 by the connecting pile 303, can achieve vertical adjustment within a certain range. This structural design allows for flexible adjustment to accommodate the thickness specifications of the cut polytetrafluoroethylene sheet.
[0023] like Figures 1 to 4As shown, the second adjustment frame assembly 4 includes a crossbeam 401, guide rails 402, lead screw 403, movable seat 404, buffer rod 405, docking seat 406, and servo motor 407. Guide rails 402 are symmetrically mounted on the bottom of the crossbeam 401, and lead screw 403 is horizontally mounted directly below the guide rails 402. Movable seat 404 is connected to the surface of lead screw 403, and buffer rod 405 is horizontally mounted on the bottom of movable seat 404. The end of buffer rod 405 near the vertical central axis of crossbeam 401 is connected to docking seat 406. Servo motors 407 are mounted on both the left and right ends of crossbeam 401. The guide rails 402, lead screw 403, movable seat 404, buffer rod 405, docking seat 406, and servo motor 407 are all mounted on the crossbeam. The vertical central axis of 401 is symmetrically arranged on both sides of the central axis, and one end of the lead screw 403 is connected to the power output end of the servo motor 407 through a coupling. The end of the docking seat 406 away from the buffer rod 405 is movably connected to one side of the limiting plate 5. The moving seat 404 is connected to the guide rail 402 and the lead screw 403 in a slotted embedded structure and a threaded connection, respectively. Under the operation of the servo motor 407, the lead screw 403 connected to it will rotate synchronously in the horizontal axis, thereby driving the moving seat 404 connected to the lead screw 403 to move horizontally, thereby pulling the buffer rod 405 connected at the bottom to move together, and thus pulling the limiting plate 5 connected by the docking seat 406 to move horizontally on the surface of the processing table 101.
[0024] In summary, as Figures 1 to 4 As shown, when using this adjustable thickness polytetrafluoroethylene (PTFE) sheet cutting equipment, the PTFE sheet to be cut is first placed horizontally on one end of the processing table 101. During this process, the first adjustment frame group 3 is started. According to the thickness of the PTFE sheet, the vertical adjustment is made by the vertical extension and retraction of the lifting rods 302 at both ends of the stabilizer 301 and the protective cover 304 connected to the lower middle part of the stabilizer 301 by the connecting pile 303.
[0025] Subsequently, the second adjustment frame group 4 at both ends of the cutting table assembly 1 will operate synchronously. The servo motor 407 at both ends of the cross frame 401 will start to operate, driving the lead screw 403 connected to its power output end to rotate horizontally. This causes the movable seat 404 connected to the lead screw 403 to move along the guide rail 402 and the surface of the lead screw 403. The bottom of the movable seat 404 is moved by the limiting plate 5 connected to one end of the buffer rod 405 by the docking seat 406, and the limiting effect is achieved on the side of the polytetrafluoroethylene plate.
[0026] Then, under the operation of the drive motor 104 at the bottom of the processing table 101, the circular saw 102 is driven to rotate at high speed. The barrier cover 103 prevents the lower end of the circular saw 102 from having unnecessary structural contact with the outside. Then, the polytetrafluoroethylene plate on the surface of the processing table 101 is pushed horizontally to contact the circular saw 102 to realize the cutting operation. During the use of the entire device, the extension and retraction of the lifting column 201 can provide vertical lifting and adjustment for the entire device, while the anti-slip pad 203 at the bottom of the stabilizing seat 202 can ensure the stability of the ground.

Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described in order to better illustrate the principles and practical applications of this utility model, and to enable those skilled in the art to understand this utility model and design various embodiments with various modifications suitable for a particular purpose.
