Description

Technical Field

[0001] The present invention relates to the technical field of bar extrusion, and particularly relates to a vertical extruder for processing low-dielectric polytetrafluoroethylene bars. Background Art

[0002] Polytetrafluoroethylene (PTFE) has been extremely widely used in many high-end fields such as electronic communication, aerospace, and chemical industry due to its excellent chemical stability, high temperature resistance, low friction coefficient, and outstanding low-dielectric properties. In these fields, strict requirements are imposed on the quality and performance of low-dielectric polytetrafluoroethylene bars.

[0003] In the existing processing technology of polytetrafluoroethylene bars, a vertical extruder is a commonly used device, but in the actual operation process, it exposes multiple technical problems that need to be solved urgently.

[0004] In the feeding link, most enterprises still adopt the method of manually feeding into the polytetrafluoroethylene raw material area. This method not only has a large labor intensity and low production efficiency, but also is extremely easy to introduce impurities, seriously affecting the dielectric properties and product quality of the bars. In addition, manual feeding is difficult to achieve accuracy and timeliness, easily leading to the situation of untimely feeding or lack of materials, thereby causing production interruption, reducing production efficiency, and increasing production costs.

[0005] In the initial stage of product production, in order to prevent the material from falling vertically, some enterprises adopt the method of backfilling with metal masses. However, due to the randomness and instability of the metal mass backfilling, it is difficult to ensure the consistency of the quality of each initial product. This not only leads to large fluctuations in product quality and low yield rate, but also increases the difficulty and cost of quality control in the production process. Moreover, due to the lack of an effective support structure for the initial raw materials, the polytetrafluoroethylene powder cannot be evenly stressed during the compression process, affecting the density and structural stability of the product.

[0006] Therefore, a vertical extruder for processing low-dielectric polytetrafluoroethylene bars is needed. Summary of the Invention

[0028] In order to make the technical means, creative features, achieved purposes and effects of the present invention easy to understand, the present invention will be further described below in conjunction with specific implementation modes.

[0029] Example 1, as Figures 1 to 7 shown, a vertical extruder for processing low-dielectric polytetrafluoroethylene rods includes a plurality of support legs 1. The upper ends of the plurality of support legs 1 are fixedly connected to a first support plate 2 in common. The middle part of the upper end of the first support plate 2 is fixedly connected to a stirring mechanism 4. The four corners of the upper end of the first support plate 2 are fixedly connected to an extrusion component 6 in common. The left end of the extrusion component 6 is fixedly connected to a material storage mechanism 5. The lower right side of the material storage mechanism 5 is fixedly connected to a feeding mechanism 7.

[0030] In the specific implementation process of the present invention, first, the entire device is installed on the second-floor ground. A hole is opened on the floor of the floor slab so that the forming mechanism 3 is vertically placed above the hole. Then, the staff first injects the prepared polytetrafluoroethylene powder into the material storage mechanism 5 and the stirring mechanism 4, and at the same time starts the internal structure of the forming mechanism 3 for preheating. Then, by starting the internal driving structure of the material storage mechanism 5, the internal structures of the stirring mechanism 4 and the material storage mechanism 5 are driven to operate at the same time. Then, by starting the internal structure of the extrusion component 6 to move up and down, the tetrafluoroethylene powder is extruded into the forming mechanism 3. Then, under the action of the internal structure of the stirring mechanism 4, the tetrafluoroethylene powder is sent into the forming mechanism 3 for melting;

[0031] When the internal structure of the extrusion assembly 6 is pressed down, it can drive the operation of the internal structure of the feeding mechanism 7, so that the internal structure of the feeding mechanism 7 seals the internal structure of the material storage mechanism 5, preventing the material storage mechanism 5 from feeding the inside of the stirring mechanism 4. Then, when the internal structure of the extrusion assembly 6 rises, it drives the movement of the internal structure of the feeding mechanism 7. Under the action of the material storage mechanism 5 inside the feeding mechanism 7, the polytetrafluoroethylene powder stored inside the material storage mechanism 5 is sent into the stirring mechanism 4 for preliminary storage, thus achieving the purpose of automatic feeding. Then, as the molten polytetrafluoroethylene powder inside the forming mechanism 3 gradually increases, the internal structure of the forming mechanism 3 is under a certain pressure, causing its internal structure to drop, and then the formed rod is extruded downward from the inside of the forming mechanism 3 and gradually moves downward through the hole opened in the floor slab.

[0032] Embodiment 2. To achieve the purpose of storing polytetrafluoroethylene powder, referring to Figure 5 , in this solution, the material storage mechanism 5 includes a second support plate 51 and a motor 53. The second support plate 51 is fixedly connected to the left end of the fixed plate 61, and the motor 53 is fixedly connected to the upper left front of the fixed plate 61. A storage barrel 52 is fixedly connected to the upper end of the second support plate 51. An inclined column 57 is fixedly connected to the lower part of the inner cavity of the storage barrel 52. A second stirring rod 56 is rotatably connected to the middle of the inclined column 57. A pulley assembly 54 is fixedly connected to the lower end of the second support plate 51. The pulley assembly 54 consists of two belt pulleys and a first belt.

[0033] Furthermore, the lower end of the right belt pulley is fixedly connected to the upper end of the rotating column 46. The lower end of the second stirring rod 56 passes through the upper end of the inclined column 57 and the bottom wall of the storage barrel 52 and extends to the outside and is fixedly connected to the upper end of the left belt pulley. The output end of the motor 53 is fixedly connected to the upper end of the right belt pulley through a coupling.

[0034] In the above, first, the staff injects the prepared polytetrafluoroethylene powder into the inner cavity of the storage barrel 52 for storage. Then, as the internal structure of the extrusion assembly 6 rises, it drives the operation of the internal structure of the feeding mechanism 7, making the internal structure of the feeding mechanism 7 in an open state. When the internal structure of the extrusion assembly 6 is lifted upward, the motor 53 is started to drive the belt pulley and the first belt to rotate, which drives the second stirring rod 56 to rotate through the belt pulley, stirring the polytetrafluoroethylene powder. While stirring, the polytetrafluoroethylene powder is stirred into the stirring mechanism 4 through the open internal structure of the feeding mechanism 7 for preliminary storage. During the stirring process, the second stirring rod 56 can also break up the agglomerated polytetrafluoroethylene powder to ensure the integrity of subsequent processing.

[0035] In the above, the specific installation method, circuit connection method, and control method of the motor 53 adopted are all conventional designs, and the present invention will not elaborate in detail.

[0036] Specifically, in order to achieve the purpose of feeding polytetrafluoroethylene powder into the stirring mechanism 4 during the stirring process, referring to Figure 6 , in this solution, the feeding mechanism 7 includes a circular ring 71 and a guide wheel 75. The circular ring 71 is fixedly connected to the right side of the middle part of the inclined column 57. The lower end of the circular ring 71 is fixedly connected with a bent pipe 72. The upper part of the inner cavity of the circular ring 71 is slidably connected with a sealing plate 73. The front side and the right side of the lower end of the sealing plate 73 are both fixedly connected with a tension spring 76. One end of the two tension springs 76 far from the same side of the sealing plate 73 is fixedly connected to the upper wall of the inner cavity of the inclined column 57. The guide wheel 75 is fixedly connected to the lower right part of the outer arc surface of the storage barrel 52. The right end of the sealing plate 73 is fixedly connected with a rope 74. The right end of the rope 74 penetrates through the inner wall of the storage barrel 52 and extends to the outside and is wound and connected to the outer surface of the guide wheel 75. One end of the guide wheel 75 far from the sealing plate 73 is fixedly connected to the lower end of the fixed block 66. The lower end of the bent pipe 72 penetrates through the upper end of the second support plate 51 and extends above the feeding tray 41.

[0037] In the above, when the fixed block 66 rises, the rope 74 wound around the surface of the guide wheel 75 is pulled upward, so that the rope 74 pulls the sealing plate 73 to move to the right in the inner cavity of the circular ring 71, making the upper end of the circular ring 71 communicate with the bent pipe 72, so that the polytetrafluoroethylene powder being stirred enters the inner cavity of the bent pipe 72 from the upper end of the circular ring 71, and the polytetrafluoroethylene powder is sent into the stirring mechanism 4 through the bent pipe 72;

[0038] Then when the fixed block 66 descends, the motor 53 stops running and the stirring rod two 56 stops stirring. At the same time, during the gradual descent of the fixed block 66, the two tension springs 76 arranged pull the sealing plate 73 to move to the left, so that the sealing plate 73 blocks the upper end of the circular ring 71 to be in a sealed state, so that the polytetrafluoroethylene powder in the inner cavity of the storage barrel 52 will not enter the stirring mechanism 4, and a certain amount of polytetrafluoroethylene powder is always maintained inside the stirring mechanism 4.

[0039] Specifically, in order to achieve the purpose of stirring the polytetrafluoroethylene powder and feeding it into the forming mechanism 3 for processing, referring to Figure 2 , in this solution, the stirring mechanism 4 includes a feeding tray 41 and a rotating column 46. The feeding tray 41 is fixedly connected to the middle part of the upper end of the first support plate 2. The upper end of the feeding tray 41 is rotatably connected with a collar 42. The outer surface of the collar 42 is fixedly connected with a gear ring 43. The lower end of the inner surface of the collar 42 is fixedly connected with a plurality of stirring rods one 44 in an annular array. The rotating column 46 is rotatably connected to the front left side of the upper end of the first support plate 2. The lower side of the outer surface of the rotating column 46 is fixedly connected with a gear 45.

[0040] Furthermore, the outer surface of the gear 45 is meshed and connected to the outer surface of the gear ring 43.

[0041] In the above, during the upward movement of the internal structure of the extrusion assembly 6, the motor 53 is started to drive the pulley to rotate, so that the polytetrafluoroethylene powder in the inner cavity of the storage barrel 52 enters the inner cavity of the feeding tray 41. At the same time, the pulley rotation drives the rotating column 46 to rotate. While the rotating column 46 rotates, it drives the gear 45 to rotate. While the gear 45 rotates, it drives the engaged gear ring 43 to rotate, thereby driving the collar 42 to rotate at the upper end of the feeding tray 41, so that it drives the stirring rod 44 to stir the polytetrafluoroethylene powder falling into the inner cavity of the feeding tray 41. While stirring, the tetrafluoroethylene powder is dialed into the through hole opened in the middle of the feeding tray 41, and then the internal structure of the extrusion assembly 6 descends to extrude the polytetrafluoroethylene powder from the through hole into the forming mechanism 3 for melting.

[0042] Specifically, in order to achieve the purpose of extruding into the forming mechanism 3, refer to Figure 3 , in this solution, the polytetrafluoroethylene powder extrusion assembly 6 includes a fixing plate 61, the fixing plate 61 is fixedly connected to the upper part of the support plate 2, the middle of the upper end of the fixing plate 61 is fixedly connected with a plunger pump 62, the lower end of the output shaft of the plunger pump 62 penetrates through the upper end of the fixing plate 61 and extends to the outside and is fixedly connected with a plug column 63, and the outer surface of the output shaft of the plunger pump 62 is fixedly connected with a bending plate 65. The upper part of the bending plate 65 is slidably connected and penetrates through the lower end of the fixing plate 61 and extends to the outside, and the left end of the upper part of the bending plate 65 is fixedly connected with a fixing block 66.

[0043] In the above, the plunger pump 62 is started to drive the plug column 63 to descend to extrude the polytetrafluoroethylene powder, and at the same time, the output shaft of the plunger pump 62 drives the bending plate 65 to move up and down to drive the rest of the components to move.

[0044] Specifically, in order to achieve the purpose of processing the polytetrafluoroethylene powder, refer to Figure 4 , in this solution, the forming mechanism 3 includes a discharge pipe 32, the heating assembly 31 is fixedly connected to the middle of the lower end of the support plate 2, the upper part of the outer surface of the heating assembly 31 is fixedly connected with the heating assembly 31, a plurality of triangular blocks 34 are fixedly connected in an annular array on the lower part of the inner surface of the discharge pipe 32, one end of the plurality of triangular blocks 34 close to the axis of the discharge pipe 32 is commonly fixedly connected with a conical block 35, the lower end of the conical block 35 is fixedly connected with a stop column 36, and a guide rod 37 is arranged in the lower part of the inner cavity of the discharge pipe 32.

[0045] In the above, the heating assembly 31 is composed of a heating box, a resistance wire and a heat conduction pipe in the prior art.

[0046] In the above, when the polytetrafluoroethylene powder enters the inner cavity of the discharge pipe 32, the discharge pipe 32 is preheated through the internal structure of the heating component 31, so that the polytetrafluoroethylene powder is heated to a molten state during the descent, and the molten polytetrafluoroethylene material flows downward from the upper end of the set cone block 35, and then flows from the gap between the outer surface of the retaining column 36 and the inner surface of the discharge pipe 32 to the upper end of the guide rod 37. Then, the pressure on the upper end of the guide rod 37 is gradually increased by the gradually increasing polytetrafluoroethylene powder. When a certain limit value of the guide rod 37 is reached, the guide rod 37 is pressed to fall from the inner cavity of the discharge pipe 32. During this process, a stable support and reaction force are provided for the polytetrafluoroethylene powder. This ensures that the powder is evenly stressed during compression, effectively avoiding density unevenness caused by the vertical falling of the material, and thus improving the overall density of the product.

[0047] It should be particularly noted that the specific installation method, circuit connection method, and control method of the plunger pump 62 used in the present invention are all conventional designs, and the present invention will not be elaborated in detail.
