Description

Technical Field

[0001] This utility model relates to the field of polytetrafluoroethylene rod processing technology, specifically to a continuous extrusion molding equipment for polytetrafluoroethylene rods. Background Technology

[0002] Polytetrafluoroethylene (PTFE) rods are rods formed from polytetrafluoroethylene resin through molding, paste extrusion, or plunger extrusion processes. They possess excellent corrosion resistance, self-lubrication, and non-stick properties, making them suitable for gaskets, seals, and lubricants operating in corrosive media, as well as electrical insulation components used at various frequencies.

[0003] Conventional continuous extrusion molding equipment for polytetrafluoroethylene (PTFE) rods is limited by its structural design. During the extrusion process, the residual heat of the material itself can cause deformation, affecting the quality of the PTFE rods. At the same time, the lack of an effective support structure makes the PTFE rods prone to deformation. Summary of the Invention

[0004] The purpose of this invention is to provide a continuous extrusion molding equipment for polytetrafluoroethylene rods to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a continuous extrusion molding equipment for polytetrafluoroethylene (PTFE) rods, comprising a PTFE rod extruder unit and a receiving trough. The output end of the PTFE rod extruder unit is horizontally provided with a receiving trough, and the bottom of the receiving trough is connected to a support assembly. Cooling assemblies are installed on both the left and right sides of the receiving trough, and a limiting frame is connected to the top of the middle of the cooling assembly. The PTFE rod extruder unit includes an extrusion molding machine body, a support base, a lifting column, and a grounding base. The bottom of the extrusion molding machine body is symmetrically provided with support bases on the left and right sides, and lifting columns are symmetrically and vertically installed at the front and rear ends of the bottom of the support base. A grounding base is provided at the bottom of the lifting column.

[0006] Furthermore, the upper end of the lifting column is movably connected to the support base, and the grounding base and the bottom end of the lifting column are welded together. Moreover, the grounding base has holes for bolt installation at its four opposite corners.

[0007] Furthermore, the support assembly includes a base, guide rails, a moving platform, limit bolts, and lifting posts. Two sets of guide rails are horizontally installed on the top surface of the base, and the moving platform is connected to the surface of the guide rails. Limit bolts are horizontally installed on both sides of the moving platform, and lifting posts are vertically installed on the top of the moving platform.

[0008] Furthermore, the bottom of the mobile platform and the guide rail are connected to each other using an embedded structure, and the limit bolt and the mobile platform are connected by a thread. Moreover, the bottom end of the lifting pile is movably installed on the top of the mobile platform.

[0009] Furthermore, the cooling assembly includes a support frame, an adjusting frame, an atomizing nozzle, a connecting hose, and a delivery pipe. The adjusting frame is symmetrically installed on the top of the support frame, and the atomizing nozzle is installed on the upper end of the adjusting frame. One end of the atomizing nozzle is connected to the connecting hose, and the end of the connecting hose away from the atomizing nozzle is connected to the delivery pipe.

[0010] Furthermore, the atomizing nozzle, connecting hose, and delivery pipe are interconnected via quick-connect structures, and both ends of the delivery pipe are equipped with quick-connect structures. The support frame is movably installed on the side of the receiving groove.

[0011] Furthermore, the limiting frame includes a gantry frame, elastic telescopic rods, and limiting rollers. Two sets of elastic telescopic rods are vertically installed in the middle of the gantry frame, and limiting rollers are connected and installed at the bottom of the elastic telescopic rods.

[0012] Furthermore, a section of the bottom of the gantry frame is movably installed at the top center of the support frame, and the cooling assembly and the limiting frame are connected and combined in an "I"-shaped structure.

[0013] This utility model provides a continuous extrusion molding equipment for polytetrafluoroethylene rods, which has the following beneficial effects: 1. This utility model features symmetrical support bases at the bottom of the extrusion molding machine body, with lifting columns vertically mounted symmetrically at the bottom of the support bases. The expansion and contraction of the lifting columns allows for vertical adjustment of the extrusion molding machine body. The grounding base at the bottom of the lifting columns has holes at its four opposite corners, which, combined with bolts, allow for maximum fixation of the entire PTFE rod extrusion unit to the ground or mounting surface, ensuring operational stability. Furthermore, the four sets of lifting columns, along with their grounding bases, can be adjusted to accommodate the stability of the ground or mounting surface, ensuring the overall stability and smooth operation of the device.

[0014] This invention features a receiving groove at the output end of a PTFE rod extruder, with a support assembly connected to its bottom. The receiving groove utilizes a bottom lifting pile structure for adjustable height within a certain range. Simultaneously, a movable platform at the bottom of the lifting pile allows the receiving groove to move horizontally along a guide rail, ensuring flexible structural adjustment to match the PTFE rod extruder's structure. This guarantees accurate receiving of PTFE rods during extrusion, ensuring stable output. Furthermore, the base and guide rail structure allows for structural expansion, as well as expansion of the movable platform and top lifting pile, enabling the splicing of multiple receiving grooves. This satisfies the continuous material receiving function of the PTFE rod extruder, guiding it to downstream equipment.

[0015] This invention features symmetrically installed cooling components on both sides of the receiving tank, with a limiting frame on top of the cooling components. When the PTFE rod is extruded and conveyed into the receiving tank, the cooling liquid is delivered to the atomizing nozzle via the connecting hose and conveying pipe. The atomizing nozzle sprays the liquid onto the surface of the PTFE rod, achieving rapid cooling and facilitating subsequent processing, thus ensuring efficient processing. The elastic telescopic rod, in conjunction with the limiting roller at the bottom, provides structural restraint above the output PTFE rod, preventing it from moving out of the receiving tank during output movement and ensuring stability during the output movement of the PTFE rod.

Furthermore, the bottom of the lifting column 103 is provided with a grounding seat 104. The upper end of the lifting column 103 is movably connected to the support seat 102, and the grounding seat 104 and the bottom end of the lifting column 103 are welded together. Moreover, the four opposite corners of the grounding seat 104 are provided with holes for bolt installation. By utilizing the structural expansion and contraction of the lifting column 103, a certain degree of lifting and lowering adjustment can be provided for the extrusion molding machine body 101 in the vertical direction. The four opposite corners of the grounding seat 104 at the bottom of the lifting column 103 are provided with holes. With the use of bolts, the entire PTFE rod extrusion unit 1 can be fixed to the ground or the mounting structure surface to the greatest extent.

[0020] like Figures 1 to 5As shown, the support assembly 3 includes a base 301, a guide rail 302, a moving platform 303, a limit bolt 304, and a lifting pile 305. Two sets of guide rails 302 are horizontally mounted on the top surface of the base 301, and the moving platform 303 is connected to the surface of the guide rails 302. Limit bolts 304 are horizontally mounted on both sides of the moving platform 303, and the lifting pile 305 is vertically mounted on the top of the moving platform 303. The bottom of the moving platform 303 and the guide rails 302 are connected to each other by an embedded structure. The limit bolts 304 and the moving platform 303 are threaded together. The bottom end of the lifting pile 305 is movably mounted on the top of the moving platform 303. The receiving groove 2 can achieve a certain range of lifting and adjustment by utilizing the structure of the bottom lifting pile 305. At the same time, the moving platform 303 at the bottom of the lifting pile 305 can drive the receiving groove 2 to move horizontally along the surface of the guide rail 302, thereby ensuring flexible structural adjustment for the receiving groove 2.

[0021] like Figures 1 to 5 As shown, the cooling assembly 4 includes a support frame 401, an adjusting frame 402, an atomizing nozzle 403, a connecting hose 404, and a delivery pipe 405. The adjusting frame 402 is symmetrically mounted on the top of the support frame 401, and the atomizing nozzle 403 is mounted on the upper end of the adjusting frame 402. One end of the atomizing nozzle 403 is connected to the connecting hose 404, and the end of the connecting hose 404 away from the atomizing nozzle 403 is connected to the delivery pipe 405. The atomizing nozzle 403, the connecting hose 404, and the delivery pipe 405 are interconnected via quick-connect couplings. Both ends of the delivery pipe 405 are equipped with quick-connect couplings. The support frame 401 is movably mounted on the side of the receiving groove 2. A limiting frame... 5 includes a gantry frame 501, elastic telescopic rods 502, and limiting rollers 503. Two sets of elastic telescopic rods 502 are vertically installed in the middle of the gantry frame 501, and the bottom of the elastic telescopic rods 502 are connected to the limiting rollers 503. One bottom section of the gantry frame 501 is movably installed in the middle of the top of the support frame 401. The cooling component 4 and the limiting frame 5 are connected and combined in an "I" shape. When the polytetrafluoroethylene rod is extruded and transported to the receiving tank 2, the liquid used for cooling can be transported to the atomizing nozzle 403 under the transport of the connecting hose 404 and the conveying pipe 405, and sprayed onto the surface of the polytetrafluoroethylene rod by the atomizing nozzle 403 to achieve rapid cooling.

[0022] In summary, as Figures 1 to 5As shown, in use, the continuous extrusion molding equipment for polytetrafluoroethylene rods first sets the bracket assembly 3 with the receiving groove 2 on one side of the output end of the PTFE rod extruder unit 1. Then, according to the specifications of the output PTFE rods, the vertical height of the extrusion molding machine body 101 is adjusted to a suitable position by using the vertical extension and retraction of the lifting column 103 at the bottom of the support base 102. During this process, the height of the receiving groove 2 connected to it is adjusted by the synchronous extension and retraction of the lifting pile 305 at the top of the moving table 303, and the structure is kept consistent with the height of the output end of the extrusion molding machine body 101. At the same time, the receiving groove 2 is moved along the surface of the guide rail 302 at the top of the base 301 by the moving table 303 and is placed against the output end of the extrusion molding machine body 101. Then, the cooling component 4 is connected to the external coolant supply device through the quick-connect structure at both ends of the conveying pipe 405. When the polytetrafluoroethylene rod is extruded and output as the main body 101 of the extrusion molding machine operates, the coolant conveyed by the connecting hose 404 and the conveying pipe 405 is sprayed onto the surface of the polytetrafluoroethylene rod under the operation of the atomizing nozzle 403 at the upper end of the adjusting frame 402 for cooling. At the same time, the elastic telescopic rod 502 in the middle of the gantry 501 will be structurally adapted to the diameter of the polytetrafluoroethylene rod within a certain range. At the same time, the structure of the limiting roller 503 can limit the polytetrafluoroethylene rod and guide its conveying.
