Description

Technical Field

[0001] The present invention relates to the technical field of material mixing equipment, and particularly relates to a polytetrafluoroethylene gasket production device and process. Background Art

[0002] The main raw material for producing polytetrafluoroethylene gaskets is polytetrafluoroethylene resin. To improve the performance of the gaskets, other reinforcing materials are added to the polytetrafluoroethylene resin. For example, when it is necessary to improve the tensile strength and compressive strength of the gasket, glass fibers can be added to the polytetrafluoroethylene resin; when it is necessary to improve the thermal conductivity of the gasket, bronze powder can be added to the polytetrafluoroethylene resin. After adding the reinforcing materials, a mixing device is required to fully mix the polytetrafluoroethylene resin and the reinforcing materials.

[0003] Chinese Patent No. CN214020420U discloses a V-shaped mixer, which includes a column, a V-shaped cylinder, and a stirring motor. A rotating shaft is horizontally arranged on the column, the V-shaped cylinder is arranged on the rotating shaft, and a discharge port is arranged at the bottom end of the V-shaped cylinder. The V-shaped cylinder includes two cylinders, the bottom ends of the two cylinders are connected to form a V-shaped structure, feed ports are arranged at the top ends of both cylinders, the stirring motor is arranged at the top end of the cylinder, the stirring motor is provided with a first stirring shaft, the first stirring shaft extends into the corresponding cylinder along the length direction of the cylinder, and a plurality of first stirring blades are arranged on the first stirring shaft in sequence along its own length direction. The distance between the end of each first stirring blade and the corresponding first stirring shaft decreases successively from the middle position of the first stirring shaft towards both ends.

[0004] The above patent improves the mixing effect by arranging the first stirring shaft and the first stirring blades in the two cylinders of the V-shaped cylinder, and driving the first stirring blades by the first stirring shaft to stir the materials in the cylinder. However, in the actual implementation process, since the V-shaped cylinder is constantly rotating, it is necessary to consider how to prevent the wires connecting the two stirring motors on the V-shaped cylinder to the power supply from getting entangled during the rotation of the V-shaped cylinder, which increases the structural complexity and construction difficulty of the mixer; if rechargeable stirring motors are used, the cost will inevitably increase, and the mixer cannot be used normally during charging, affecting the production efficiency.

[0005] In addition, when more materials are added into the V-shaped cylinder, at the initial stage of the rotation of the V-shaped cylinder, during the process of the materials located in the upper layer at the time of addition following the rotation of the V-shaped cylinder, they will first enter the two cylinders, and the materials located in the lower layer at the time of addition will enter the cylinders later. When the two cylinders are flipped to the directly lower position, the materials located in the upper layer at the time of addition are located in the lower layer at this time, and the materials located in the lower layer at the time of addition are located in the upper layer at this time. When the two cylinders continue to flip, the materials located in the lower layer at the time of addition will flow out of the two cylinders first and are still in the lower layer, while the materials located in the upper layer at the time of addition will flow out of the two cylinders later and are still in the upper layer. Therefore, in the initial stage of mixing, the materials in the upper and lower layers cannot be well mixed, and the stirring direction of the stirring blades is also along the radial direction of the cylinder, which cannot play a good role in replacing the positions of the materials in the upper and lower layers. It takes a long time to run before a sufficient mixing effect can be achieved.

[0006] Therefore, there is a need in the art for a polytetrafluoroethylene gasket production device and process to solve the above problems. Summary of the Invention

[0007] The present invention provides a polytetrafluoroethylene gasket production device and process, aiming to solve the problems of high construction difficulty and low mixing efficiency of the equipment for mixing the production raw materials of polytetrafluoroethylene gaskets in the related art.

[0008] On the one hand, the present invention provides a polytetrafluoroethylene gasket production device, including a frame, a V-shaped cylinder rotatably arranged on the frame, and a first driving assembly for driving the V-shaped cylinder to rotate. The V-shaped cylinder includes two inclined cylinders communicated with each other and a discharge cylinder communicating the two cylinders. Feed ports are respectively opened at the tops of the two cylinders, and a conical partition cylinder is fixedly connected at a position in the cylinder near the feed port. The diameter of the partition cylinder decreases from the position near the feed port to the position away from the feed port, and both ends of the partition cylinder are of an open structure.

[0009] By setting the partition cylinder in the present invention, during the rotation of the V-shaped cylinder, the partition cylinder and the cylinder cooperate to form a diversion of the materials, so that the materials originally located in the upper layer first flow between the partition cylinder and the inner wall of the cylinder. After the space between the partition cylinder and the cylinder is filled, the materials located in the lower layer can only enter between the partition cylinder and the feed port from the partition cylinder. When the cylinder continues to rotate, the materials between the partition cylinder and the cylinder will first flow to the lower layer, while the materials between the partition cylinder and the feed port will flow to the upper layer later. As the V-shaped cylinder rotates continuously, the materials in the upper and lower layers are repeatedly replaced and mixed, so that the materials are quickly and evenly mixed, shortening the mixing time and improving the mixing efficiency. In addition, the V-shaped cylinder structure of the present invention is simple and compact, without the need to set a driving source other than the first driving assembly, reducing the production cost and eliminating the need to consider the layout of the driving source circuit, reducing the construction difficulty.

[0010] Preferably, a first knocking component is arranged inside the cylinder body. The first knocking component is located on the side of the partition cylinder away from the feed port, and the first knocking component is used to knock the inner wall of the cylinder body.

[0011] The first knocking component knocks the inner wall of the cylinder body, which can effectively break the material jamming that may form between the partition cylinder and the inner wall of the cylinder body, prompt the material to resume flowing again, avoid the problems of unsmooth or even blocked material flow caused by local material accumulation and jamming, and ensure that the material can move smoothly and evenly throughout the cylinder body.

[0012] Preferably, the first knocking component includes a mounting frame fixedly installed inside the cylinder body and a knocking rod slidably connected in the mounting frame along the radial direction of the cylinder body. A driving structure for driving the knocking rod to move along the mounting frame is arranged inside the cylinder body.

[0013] The knocking rod is slidably connected in the mounting frame along the radial direction of the cylinder body. This radial arrangement enables the knocking rod to directly and accurately knock the inner wall of the cylinder body. The direction of the radial knocking force is consistent with the required direction of the force on the inner wall of the cylinder body, which can more effectively transmit the knocking force to the inner wall of the cylinder body, thereby more effectively preventing the material from getting stuck between the partition cylinder and the inner wall of the cylinder body, ensuring the smooth flow of the material inside the cylinder body, and guaranteeing the stability and reliability of the device operation.

[0014] Preferably, a hydraulic cavity is formed inside the mounting frame. The knocking rod is slidably arranged along the radial direction of the cylinder body in the hydraulic cavity. Two knocking rods located on the same diameter of the cylinder body are elastically connected. The hydraulic cavity is filled with hydraulic oil. A pressing rod is slidably connected to the mounting frame along the axial direction of the cylinder body. One end of the pressing rod extends into the hydraulic cavity. When the driving structure pushes the pressing rod into the hydraulic cavity, the pressing rod knocks the inner wall of the cylinder body by pressing the hydraulic oil to push the knocking rod.

[0015] The pressing rod is slidably connected to the mounting frame along the axial direction of the cylinder body, and one end of the pressing rod extends into the hydraulic cavity. This structural design makes the entire power transmission and knocking mechanism layout compact and occupies little space. In the limited space of the cylinder body, the knocking function can be efficiently realized; using the hydraulic oil filled in the hydraulic cavity as the power transmission medium, when the driving structure pushes the pressing rod into the hydraulic cavity, the hydraulic oil can evenly and stably transmit the pushing force of the pressing rod to the knocking rod, realizing the effective amplification and transmission of force.

[0016] Preferably, the driving structure includes a gravity rod slidably arranged along the axial direction of the cylinder body inside the cylinder body. During the rotation of the V-shaped cylinder, the gravity rod pushes the pressing rod or cancels the pushing of the pressing rod under the action of its own gravity.

[0017] Only a gravity rod sliding along the axial direction of the cylinder is used as the key component of the driving structure, and the overall structure is extremely simple. This simple design avoids the use of complex and expensive driving components and supporting transmission mechanisms, greatly reducing the manufacturing cost of the equipment; and the gravity of the gravity rod is used to push or cancel the pushing of the extrusion rod without providing an additional power source, which not only reduces the energy consumption of the equipment, but also avoids the complex problems of circuit and gas path layout caused by external power or gas source, reducing the energy consumption cost and maintenance cost during the operation of the equipment.

[0018] Preferably, a mounting ring is fixedly installed in the separation cylinder, and the gravity rod is slidably arranged in the mounting ring along the axial direction of the cylinder body, and a space for materials to pass through is reserved between the gravity rod and the separation cylinder.

[0019] A mounting ring is fixedly installed in the separation cylinder, and the gravity rod is slidably arranged in the mounting ring along the axial direction of the cylinder. This design provides a stable installation and sliding basis for the gravity rod. The fixed setting of the mounting ring can ensure that the gravity rod maintains an accurate axial sliding trajectory during operation, avoids the driving effect due to shaking or deviation, and improves the reliability and stability of the entire driving structure. Moreover, by setting the gravity rod in the separation cylinder, during the movement of the gravity rod, the gravity rod can loosen the material in the separation cylinder, thereby facilitating the smooth flow of material in the separation cylinder.

[0020] Preferably, a second knocking assembly is provided in the cylinder body, and the second knocking assembly is located on the side of the separation cylinder close to the feed port. The structure of the second knocking assembly is the same as that of the first knocking assembly. The gravity rod is located between the first knocking assembly and the second knocking assembly, and the gravity rod alternately squeezes the extrusion rods of the first knocking assembly and the second knocking assembly during the rotation of the V-shaped cylinder.

[0021] By setting up the second knocking assembly, during the rotation of the V-shaped cylinder, when the feed port rotates from top to bottom, the gravity rod squeezes the extrusion rod of the second knocking assembly, so that the knocking rod of the second knocking assembly knocks on the inner wall of the cylinder, which is conducive to the smooth entry of materials into the space between the separation cylinder and the feed port; the first knocking assembly and the second knocking assembly have the same structure and share the same gravity rod as the driving component, making the structure of the entire knocking system more compact.

[0022] Preferably, the V-shaped cylinder is rotatably connected to the frame via a support rod, a stirring assembly is arranged in the V-shaped cylinder, the stirring assembly includes stirring rod 1 and stirring rod 2 rotatably connected to the frame, the stirring rod 1 and the stirring rod 2 are horizontally penetrated in the corresponding cylinder bodies, and the stirring rod 1 and the stirring rod 2 are coaxially arranged with the support rod, a stirring rod 3 extending vertically is arranged in the discharging cylinder, stirring blades are arranged on the stirring rod 1, the stirring rod 2 and the stirring rod 3, and the stirring rod 1, the stirring rod 2 and the stirring rod 3 are connected via a transmission assembly, and a driving assembly 2 for driving the stirring rod 1 to rotate is arranged on the frame.

[0023] When the stirring rod 1 rotates, the stirring rod 3 and the stirring rod 2 are driven to rotate through the transmission assembly, so that the stirring blades stir the materials in the V-shaped cylinder in different directions, further improving the mixing effect and mixing efficiency.

[0024] Preferably, the transmission assembly includes a bevel gear one fixedly connected to the stirring rod one, a bevel gear two fixedly connected to the stirring rod two, and a bevel gear three fixedly connected to the stirring rod three. The bevel gear one and the bevel gear two are symmetrically arranged on both sides of the bevel gear three and are respectively meshed with the bevel gear three.

[0025] The bevel gear transmission has the advantages of high transmission efficiency and low power loss, which can ensure that the stirring rods 2 and 3 obtain sufficient power for stirring operations; and the bevel gear 1 and the bevel gear 2 are symmetrically arranged on both sides of the bevel gear 3. This layout enables the stirring rods 1, 2 and 3 to stir at different positions in the cylinder, covering a larger stirring area, reducing stirring dead angles, and allowing the materials to be more fully mixed and stirred in the cylinder, thereby improving the stirring effect.

[0026] On the other hand, the present invention also provides a polytetrafluoroethylene gasket production process, using the polytetrafluoroethylene gasket production device described in any one of the above preferred technical solutions, the polytetrafluoroethylene gasket production process comprises the following steps: Adding production raw materials into the V-shaped barrel from the feed port according to a predetermined ratio, and controlling the driving component 1 to drive the V-shaped barrel to rotate, so that the production raw materials are fully mixed in the V-shaped barrel; Put the mixed raw materials into a mold and press them into shape; Sintering the formed gasket and cooling the sintered gasket; The cooled gasket is cut into predetermined shapes.

[0027] The beneficial effects of the polytetrafluoroethylene gasket production process of the present invention are the same as the beneficial effects of the polytetrafluoroethylene gasket production device of the present invention, which will not be described in detail here.

[0028] The beneficial effects of the present invention are as follows: By providing a partition cylinder and setting it as a conical structure, when the V-shaped cylinder is in a rotating state, the partition cylinder and the cylinder body cooperate to perform a material diversion operation. During this process, the materials originally in the upper layer will first flow to the area between the partition cylinder and the inner wall of the cylinder body. After this space is filled with materials, the materials in the lower layer can only enter the space formed by the partition cylinder and the feed port through the partition cylinder. As the cylinder body continues to rotate, the materials between the partition cylinder and the inner wall of the cylinder body will first flow to the lower layer area, and the materials between the partition cylinder and the feed port will then flow to the upper position. In this way, with the continuous rotation of the V-shaped cylinder, the upper and lower layer materials can repeatedly exchange positions and be fully mixed, thereby realizing the rapid and uniform mixing of materials, effectively shortening the mixing time, and greatly improving the mixing efficiency. In addition, the V-shaped cylinder of the present invention has a simple and compact design and does not require an additional drive source other than the drive assembly 1. This not only reduces the production cost but also eliminates the consideration of the drive source circuit layout, significantly reducing the construction difficulty.

Detailed implementation manner

[0036] The embodiments of the present invention will be described in detail below. The examples of the embodiments are shown in the drawings. The embodiments described below with reference to the drawings are exemplary and are intended to explain the present invention and should not be construed as a limitation of the present invention.

[0037] As Figures 1 to 6 shown, a polytetrafluoroethylene gasket production device of the present invention includes a frame 1, a V-shaped cylinder 2 rotatably arranged on the frame 1, and a first driving assembly for driving the V-shaped cylinder 2 to rotate. The V-shaped cylinder 2 includes two left and right inclined cylinder bodies 21 communicating with each other and a discharge cylinder 22 connecting the two cylinder bodies 21. Feed inlets 23 are respectively opened at the tops of the two cylinder bodies 21, a discharge outlet 24 is opened at the bottom of the discharge cylinder 22, and end covers 25 are provided at both the feed inlet 23 and the discharge outlet 24.

[0038] Support rods 3 are respectively fixedly connected to the left and right sides of the V-shaped cylinder 2, and the support rods 3 are rotatably connected to the frame 1. The first driving assembly includes a first motor (not shown in the figure), a first gear (not shown in the figure), and a first gear ring 31. The first motor is fixedly installed on the frame 1, the first gear is fixedly connected to the output end of the first motor, the first gear ring 31 is fixedly connected to the right support rod 3, and the first gear ring 31 meshes with the first gear. The first motor drives the first gear to drive the first gear ring 31 to rotate, and the first gear ring 31 drives the support rod 3 and the V-shaped cylinder 2 to rotate, so as to realize the mixing of materials in the V-shaped cylinder 2.

[0039] A conical partition cylinder 4 is fixedly connected inside the cylinder body 21 near the feed inlet 23. The diameter of the partition cylinder 4 gradually decreases from the position near the feed inlet 23 to the position away from the feed inlet 23. Both ends of the partition cylinder 4 are open structures and do not affect the flow of materials in the cylinder body 21.

[0040] After adding materials into the V-shaped cylinder 2 through the feed inlet 23, the materials will accumulate at the connection of the discharge cylinder 22 and the two cylinders 21. When the feed inlet 23 of the V-shaped cylinder 2 rotates from top to bottom, the materials originally located in the upper layer in the V-shaped cylinder 2 will flow first and enter between the inner wall of the partition cylinder 4 and the cylinder 21, while most of the materials originally located in the lower layer will enter the partition cylinder 4 and flow to the feed inlet 23. During the continuous rotation of the V-shaped cylinder 2, the feed inlet 23 of the V-shaped cylinder 2 rotates from bottom to top. The materials between the partition cylinder 4 and the inner wall of the cylinder 21 will flow downward first, that is, the materials originally located in the upper layer will flow to the lower layer first, and then the materials between the partition cylinder 4 and the feed inlet 23 will flow, that is, most of the materials originally located in the lower layer will flow to the upper layer, realizing the replacement and mixing of the positions of the upper and lower layer materials, so that the materials can be quickly and evenly mixed, shortening the mixing time and improving the mixing efficiency.

[0041] As Figures 2 to 4 shown, a first knocking assembly is arranged in the cylinder 21. The first knocking assembly is located on the side of the partition cylinder 4 away from the feed inlet 23, and the first knocking assembly is used to knock the inner wall of the cylinder 21. The first knocking assembly includes a mounting frame 5 fixedly installed in the cylinder 21 and a knocking rod 51 slidably connected to the mounting frame 5 along the radial direction of the cylinder 21. A driving structure for driving the knocking rod 51 to move along the mounting frame 5 is arranged in the cylinder 21. By driving the knocking rod 51 to knock the inner wall of the cylinder 21 through the driving structure, the cylinder 21 vibrates, avoiding the materials from getting stuck between the partition cylinder 4 and the inner wall of the cylinder 21 and unable to flow.

[0042] The mounting frame 5 is cross-shaped, and a hydraulic cavity 52 is formed in the mounting frame 5. The knocking rod 51 is slidably arranged along the radial direction of the cylinder 21 in the hydraulic cavity 52. There are two knocking rods 51, and the two knocking rods 51 are located on the straight line of the same diameter of the cylinder 21. The two knocking rods 51 are elastically connected by a spring 53. The hydraulic cavity 52 is filled with hydraulic oil (not shown in the figure). One side of the mounting frame 5 facing the feed inlet 23 is slidably connected with a pressing rod 54 along the axial direction of the cylinder 21, and one end of the pressing rod 54 extends into the hydraulic cavity 52. When the driving structure pushes the pressing rod 54 into the hydraulic cavity 52, the pressing rod 54 pushes the knocking rod 51 to move towards the inner wall of the cylinder 21 by pressing the hydraulic oil, knocking the inner wall of the cylinder 21. When the driving structure cancels the pushing of the pressing rod 54, the two knocking rods 51 move towards each other under the elastic force of the spring 53, and the two knocking rods 51 press the hydraulic oil to push the pressing rod 54 upward to reset the pressing rod 54.

[0043] Continue to refer to Figures 2 to 4The driving structure includes a gravity rod 6 that is slidably disposed in the cylinder 21 along the axial direction of the cylinder 21. During the rotation of the V-shaped cylinder 2, the gravity rod 6 pushes the extrusion rod 54 or cancels the push on the extrusion rod 54 under the action of its own gravity. A mounting ring 41 is fixedly installed in the separation cylinder 4 through a connecting rod 40. The gravity rod 6 is slidably disposed in the mounting ring 41 along the axial direction of the cylinder 21. The mounting ring 41 guides the movement of the gravity rod 6. A space is reserved between the gravity rod 6 and the separation cylinder 4 for the material to pass through. By setting the gravity rod 6 in the separation cylinder 4, during the movement of the gravity rod 6, the gravity rod 6 can loosen the material in the separation cylinder 4, so as to facilitate the smooth flow of the material in the separation cylinder 4.

[0044] A second knocking assembly is provided in the cylinder 21, and the second knocking assembly is located on the side of the separation cylinder 4 close to the feed port 23. The structure of the second knocking assembly is the same as that of the first knocking assembly, and the extrusion rod 54 of the second knocking assembly is located on the side of the mounting frame 5 away from the feed port 23. The gravity rod 6 is located between the extrusion rods 54 of the first knocking assembly and the second knocking assembly. During the rotation of the V-shaped cylinder 2, when the feed port 23 is located at the top, the gravity rod 6 pushes the extrusion rod 54 of the first knocking assembly under the action of its own gravity, so that the knocking rod 51 knocks the inner wall of the cylinder 21, which is conducive to the smooth falling of the material entering between the separation cylinder 4 and the inner wall of the cylinder 21; when the feed port 23 is located at the bottom, the gravity rod 6 pushes the extrusion rod 54 of the second knocking assembly under the action of its own gravity, so that the knocking rod 51 of the second knocking assembly knocks the inner wall of the cylinder 21, which is conducive to the smooth entry of the material between the separation cylinder 4 and the feed port 23.

[0045] like Figure 2 , Figure 5 and Figure 6 As shown, in order to further enhance the mixing effect and improve the mixing efficiency, in this embodiment, a stirring assembly is arranged in the V-shaped barrel 2, and the stirring assembly includes a stirring rod 1 7 and a stirring rod 2 8 rotatably connected to the frame 1, the stirring rod 1 7 and the stirring rod 2 8 are arranged symmetrically, and the stirring rod 1 7 and the stirring rod 2 8 are horizontally penetrated in the corresponding barrel 21, and the stirring rod 1 7 and the stirring rod 2 8 are sleeved in the corresponding support rod 3 and are arranged coaxially with the support rod 3. A mounting rod 26 is fixedly connected in the discharge barrel 22, and a stirring rod 3 9 extending vertically is rotatably connected to the mounting rod 26.

[0046] Stirring rod 1 7, stirring rod 2 8 and stirring rod 3 9 are respectively provided with stirring blades 10, and stirring rod 1 7, stirring rod 2 8 and stirring rod 3 9 are connected by transmission assembly. A driving assembly 2 for driving stirring rod 1 7 to rotate is provided on the frame 1. When stirring rod 1 7 rotates, stirring rod 3 9 and stirring rod 2 8 are driven to rotate through the transmission assembly, so that stirring blades 10 stir the materials in the V-shaped cylinder 2 in different directions, further improving the mixing effect and mixing efficiency.

[0047] Continue to refer to Figure 2 、 Figure 5 and Figure 6 As shown in FIGS.

[0048] The second driving assembly includes a second motor (not shown in the figure), a second gear (not shown in the figure), and a second gear ring 72. The second motor is fixedly installed on the frame 1, the second gear is fixedly connected to the output end of the second motor, the second gear ring 72 is fixedly connected to one end of the first stirring rod 7, and the second gear ring 72 meshes with the second gear.

[0049] The second motor drives the second gear to drive the second gear ring 72 to rotate. The second gear ring 72 drives the first stirring rod 7 and the first bevel gear 71 to rotate. The first bevel gear 71 drives the third bevel gear 91 and the third stirring rod 9 to rotate. The third bevel gear 91 drives the second bevel gear 81 and the second stirring rod 8 to rotate, so as to realize the synchronous rotation of the first stirring rod 7, the second stirring rod 8 and the third stirring rod 9, and the rotation directions of the first stirring rod 7 and the second stirring rod 8 are opposite, so as to stir and mix the materials from different directions, thereby further improving the mixing efficiency and mixing effect.

[0050] The specific working principle of a polytetrafluoroethylene gasket production device of the present invention is as follows: Materials are added into the V-shaped cylinder 2 through the feed inlet 23, and then the end cover 25 is closed. The motor one is controlled to drive the support rod 3 to drive the V-shaped cylinder 2 to rotate. During the rotation of the V-shaped cylinder 2, when the feed inlet 23 rotates from top to bottom, the materials originally located in the upper layer in the V-shaped cylinder 2 will flow first and enter between the inner wall of the partition cylinder 4 and the cylinder body 21, while most of the materials originally located in the lower layer will enter the partition cylinder 4 and flow to the feed inlet 23. Under the action of its own gravity, the gravity rod 6 pushes against the extrusion rod 54 of the second knocking component, so that the knocking rod 51 of the second knocking component knocks on the inner wall of the cylinder body 21, which is beneficial for the materials to smoothly enter between the partition cylinder 4 and the feed inlet 23 through the partition cylinder 4; During the continuous rotation of the V-shaped cylinder 2, the feed inlet 23 of the V-shaped cylinder 2 rotates from bottom to top. The materials between the partition cylinder 4 and the inner wall of the cylinder body 21 will flow downward first, that is, the materials originally located in the upper layer will flow to the lower layer first, and then the materials between the partition cylinder 4 and the feed inlet 23 will flow, that is, most of the materials originally located in the lower layer will flow to the upper layer, realizing the replacement and mixing of the upper and lower layer materials, making the materials quickly mixed. Under the action of its own gravity, the gravity rod 6 pushes against the extrusion rod 54 of the first knocking component, so that the knocking rod 51 of the first knocking component knocks on the inner wall of the cylinder body 21, which is beneficial for the materials entering between the partition cylinder 4 and the inner wall of the cylinder body 21 to fall smoothly.

[0051] A polytetrafluoroethylene gasket production process uses the polytetrafluoroethylene gasket production device in the above embodiment. The polytetrafluoroethylene gasket production process includes the following steps: Add the production raw materials into the V-shaped cylinder 2 from the feed inlet 23 according to a predetermined ratio, and control the drive assembly one to drive the V-shaped cylinder 2 to rotate, so that the production raw materials are fully mixed in the V-shaped cylinder 2; Put the mixed raw materials into a mold and press them into shape; Sinter the formed gasket and cool the sintered gasket; Cut the cooled gasket according to a preset shape.

[0052] It can be understood that the first knocking component described in the above embodiment includes the mounting frame 5 and the knocking rod 51, which is not the only implementation form of the first knocking component. In other embodiments, the first knocking component can also be set to include at least one knocking hammer. The knocking hammer includes a connecting rod and a knocking ball head. One end of the connecting rod is hinged to the inner wall of the cylinder body 21, and the other end is integrally formed with the knocking ball head. During the rotation of the V-shaped cylinder 2, the knocking ball head drives the connecting rod to rotate in the cylinder body 21 under the action of its own gravity, so as to realize the knocking of the knocking ball head on the inner wall of the cylinder body 21.

[0053] Although the embodiments of the present invention have been shown and described above, it is to be understood that the above embodiments are exemplary and should not be construed as limiting the present invention. Those of ordinary skill in the art can make changes, modifications, substitutions, and variations to the above embodiments within the scope of the present invention.
