Description

Technical Field

[0001] The present invention relates to the technical field of cable processing, and particularly to a preheating device for processing radio frequency feeder cables. Background Art

[0002] The preheating device for processing radio frequency feeder cables is a special equipment used for precisely preheating the inner conductor precursor of the conductor during the production and processing of radio frequency feeders. Its core function is to regulate the temperature of the conductor through non-contact heating methods such as high-frequency induction and radio frequency heating, laying a foundation for subsequent processes such as extruding the insulating layer, longitudinally wrapping the outer conductor, and forming the sheath. Ultimately, it ensures the signal transmission stability, insulating layer uniformity, and overall structural reliability of the radio frequency feeder, and is widely used in the large-scale production of feeders in fields such as communication. At the present stage, during the preheating process of radio frequency feeder cables, surface impurities in the material (such as uncleaned oil stains, copper chips, and dust) will, due to the increase in temperature during preheating, cause the impurities on the conductor surface to be carried to the inner layer of the mold, accumulate and block in the inner layer of the mold, resulting in scratches on the conductor surface. The scratches on the conductor surface will damage its structural integrity, leading to a decline in mechanical properties and electrical properties, such as the voltage standing wave ratio (VSRW) not meeting the requirements, and the appearance quality not meeting the standards, affecting the use. Summary of the Invention

[0003] In order to overcome the deficiencies of the prior art, the present invention provides a preheating device for processing radio frequency feeder cables.

[0004] To solve the above technical problems, the present invention provides the following technical solution: A preheating device for processing radio frequency feeder cables includes a preheater. A placement cylinder is fixedly connected to the outside of the preheater. An outlet housing is fixedly connected to the top of the placement cylinder. A blocking plate is fixedly connected to the top of the outlet housing. A connecting arm is fixedly connected to the inner wall of the placement cylinder. A main control component for treating impurities on the surface of the cable conductor is provided on the connecting arm. An active column and a trigger disc are provided in the main control component. The cooperation of the active column and the trigger disc can provide power for treating impurities on the surface of the cable conductor. An extension column is provided in the main control component. The extension column is fixedly connected to the connecting arm. The connecting arm is U-shaped. A bearing is provided on the extension column. The inner ring of the bearing of the extension column is fixedly connected to the active column. The bottom of the extension column is movably connected to a transmission column. A machine housing is fixedly connected to the outside of the extension column. A servo motor is provided inside the machine housing. The output shaft of the servo motor is fixedly connected to the transmission column. A first gear is fixedly connected to the outside of the transmission column. A second gear is fixedly connected to the outside of the active column. The second gear meshes with the first gear. The trigger disc is fixedly connected to the outside of the active column. A fixing block is provided at one end of the active column away from the extension column. The fixing block is movably connected to the active column. A placement frame is fixedly connected to the bottom of the fixing block. The placement frame is fixedly connected to the placement cylinder.

[0005] With the above technical solution, when the radio frequency feeder cable needs to be preheated, the preheater is started first. When the adjustment needs to be made according to the specifications of the radio frequency feeder cable, the servo motor is started. The servo motor drives the transmission column to rotate. When the transmission column rotates, it drives the first gear to rotate. When the first gear rotates, it drives the meshing second gear to rotate. When the second gear rotates, it drives the movable column to rotate. When the movable column rotates, it provides power for processing impurities.

[0006] In a preferred embodiment of the present invention, a placement block is fixedly connected inside the placement cylinder. The placement block is equipped with a self-lifting component for cooperating with the main control component. The self-lifting component contains a lifting arm and a trigger post. The cooperation of the lifting arm and trigger post provides power for cable material connection. A positioning platform is provided inside the self-lifting component and is fixedly connected to the inner wall of the placement cylinder. The positioning platform consists of a square block and a cylinder. The cylindrical portion of the positioning platform is movably connected to the lifting arm. A transfer post is movably connected to the placement block. A bonding strip is fixedly connected to the outer side of the transfer post. A lifting strip is fixedly connected to the end of the transfer post away from the bonding strip. A connecting post is fixedly connected to the lifting strip. A connecting post is located on the end of the lifting post away from the lifting strip. The main lifting bar is fixedly connected to the end, and a fixed lifting block is movably connected to the main lifting bar. The fixed lifting block is H-shaped, and its top is movably connected to the lifting arm. The end of the lifting arm away from the positioning table is connected to a lifting frame, which is U-shaped. A positioning bolt is fixedly connected to the trigger post, and the lifting frame is movably connected to the positioning bolt. A limit post is fixedly connected to the bottom of the trigger post, and the limit post is inserted into the placement frame. The trigger plate is elliptical. The bonding strip and the lifting bar are distributed correspondingly with the transmission post as the center. The trigger plate is in contact with the bonding strip. When the end of the trigger plate away from the moving post rotates to be in contact with the bonding strip, the end of the bonding strip away from the transmission post rotates to the bottom, and the end of the lifting bar away from the transmission post rotates to the top.

[0007] Through the above technical solution, when the movable column rotates, it drives the trigger disc to rotate as well. Simultaneously, the trigger disc continuously presses against the bonding strip. When the end of the trigger disc away from the movable column rotates to be in contact with the bonding strip, the trigger disc presses the end of the bonding strip away from the transmission column to the bottom. Then, as the bonding strip rotates, it drives the end of the lifting strip away from the transmission column to rotate to the top. As the lifting strip rises, it drives the connecting column to rotate. As the connecting column rotates, it drives the main lifting bar to rise. As the main lifting bar rises, it drives the fixed lifting block to move towards the top. As the fixed lifting block moves, it drives the lifting arm to rise along the cylindrical part of the vibrating cylinder. As the lifting arm rises... The lifting frame moves, which in turn moves the positioning bolt. The positioning bolt then moves the trigger post toward the top placement platform. When preheating is required for other specifications of RF feeder cables, the end of the trigger plate away from the movable post rotates to be in contact with the bonding strip. The bonding strip then drives the main start bar to reset via the connecting post. When the main start bar resets, it drives the fixed start block to move toward the bottom. The fixed start block then drives the lifting arm to move toward the bottom. Subsequently, the lifting arm drives the lifting frame to move toward the bottom. As the lifting frame moves, it drives the positioning bolt, and the positioning bolt, through the trigger post, drives the limit post to move toward the bottom of the placement frame.

[0008] As a preferred embodiment of the present invention, the placement frame is provided with a vibration component to prevent the collection of impurities. The vibration component contains a pressing block, which is fixedly connected to a positioning bolt. A vibration cylinder is fixedly connected to the top of the placement frame. A striking block is provided inside the vibration cylinder. The two ends of the striking block are fixedly connected to the inner wall of the vibration cylinder and a tension spring, respectively. The tension spring is located inside the vibration cylinder. When the pressing block moves towards the bottom, the pressing block is in contact with the top of the pressing column. When the pressing block moves towards the bottom to the maximum distance, the tension spring is in contact with the bottom of the vibration cylinder.

[0009] With the above technical solution, when the positioning bolt moves towards the bottom, the positioning bolt drives the lower pressure block to move towards the top of the lower pressure column. Then, the lower pressure block squeezes the lower pressure column as it moves. After being squeezed by the lower pressure block, the lower pressure column moves towards the inside of the vibrating cylinder. As the lower pressure column moves, it drives the striking block to stretch, and the lower pressure column drives the tension spring to move towards the bottom. When the lower pressure block moves to the maximum distance towards the bottom, the lower pressure column drives the tension spring to hit the vibrating cylinder and generate vibration. The generated vibration will cause the impurities stuck on the inner wall of the storage cylinder to vibrate and fall into the bottom of the storage cylinder.

[0010] As a preferred embodiment of the present invention, the movable column is provided with a self-adjusting component for cooperating with the self-lifting component. The self-adjusting component contains a track plate and a turntable. The track plate and turntable can be adjusted according to the nature of the impurities through their cooperation. The self-adjusting component contains a connecting platform, which is movably connected to the placement frame. Four track plates are fixedly connected to the outer side of the connecting platform. The turntable is fixedly connected to the end of the movable column away from the second gear. A fitting column is fixedly connected to the outer side of the turntable. Four placement platforms are fixedly connected to the top of the connecting platform. Two limiting cylinders are fixedly connected to each placement platform. Each limiting cylinder contains a spring. The two ends of each spring are fixedly connected to the inner wall of the corresponding limiting cylinder and a blocking block, respectively. The blocking block consists of an inclined block and a disc. Each placement platform has two movable slots for placing the blocking blocks. The tilting blocks of each block are inserted into the movable slots of the placement platform. Each placement platform has a storage cylinder inserted into it. The bottom of each storage cylinder has a stop groove for placing the tilting block of the corresponding blocking block. The tilting block of each blocking block is inserted into the stop groove of the storage cylinder. The top of the blocking plate has a circular groove for placing the storage cylinder. When the trigger pin enters the placement platform, the trigger pin pushes the corresponding storage cylinder to rise into the circular groove of the blocking plate. Each track piece is an arc-shaped spherical piece. The top of each track piece has a semi-circular groove for placing the turntable. There is a placement groove for placing the bonding column between every two track pieces. When the bonding column rotates to the position corresponding to the placement groove between the two track pieces, the bonding column enters the placement groove between the two track pieces. The position of each track piece corresponds to the placement platform outside the rotating column.

[0011] With the above technical solution, when the trigger post rises toward the position of the corresponding placement platform, the trigger post enters the interior of the corresponding placement platform. Then the trigger post comes into contact with the corresponding blocking block, and the trigger post squeezes the two blocking blocks to move toward the position of the limiting cylinder. When the blocking blocks move, they drive the spring to compress. Then, when the two blocking blocks move, they release the connection with the storage cylinder blocking groove. Then the trigger post drives the storage cylinder to move toward the top, and then the trigger post pushes the corresponding storage cylinder to rise into the circular groove of the blocking plate.

[0012] As a preferred embodiment of the present invention, each storage cylinder is provided with a self-connecting assembly for automatically connecting cable materials at its top. The self-connecting assembly has a recessed block inside, which is fixedly connected to the top of the corresponding storage cylinder. Each storage cylinder is hollow, and each storage cylinder is provided with an inlet window for collecting impurities at its top. The recessed block has a slot for placing a card block, which is engaged in the slot of the recessed block. Two extension platforms are fixedly connected to the outer side of the card block. A movable bolt is fixedly connected to the card block, and two scraping blocks are movably connected to the outer side of the movable bolt. Each scraping block is semi-arc-shaped, and a fitting piece is fixedly connected to the top of each scraping block. A scraper is fixedly connected to the top of the movable bolt, and the scraper and the two scraping blocks form a circle. A inclined spring is fixedly connected to the top of each extension platform, and the end of each inclined spring away from the corresponding extension platform is fixedly connected to the corresponding scraping block.

[0013] Through the above technical solution, when the storage cylinder is lifted, the corresponding storage cylinder drives the groove block to lift. When the groove block is lifted, it drives the locking block to lift. When the locking block moves, it drives the movable bolt to move towards the RF feed cable. Then, when the two bonding pieces contact the RF feed cable, the semi-circular positions of the two bonding pieces are squeezed by the RF feed cable. The squeezed bonding pieces drive the corresponding scraper block to expand and rotate along the movable bolt. When the scraper block rotates, it drives the inclined spring to compress. When the RF feed cable is completely inside the scraper block, the compressed inclined spring rebounds and drives the two scraper blocks to return to the bonding state. Then, when the RF feed cable moves, the scraper and the scraper block work together to scrape off the impurities on the RF feed cable. The scraped impurities enter the storage cylinder from the corresponding storage cylinder inlet.

[0014] Compared with the prior art, the beneficial effects that this invention can achieve are:

[0015] 1. This invention utilizes the cooperation of a main control component, a self-lifting component, and a self-adjusting component. The semi-circular scraping block and scraper of the self-connecting component form a closed-loop scraping structure. When the bonding sheet is squeezed by the cable, it drives the scraping block to expand adaptively. The rebound of the inclined spring ensures that the scraping block is tightly attached to the outer wall of the cable conductor. When the RF feeder with the physically foamed insulation layer moves, the scraping block and scraper simultaneously scrape off oil, dust, copper shavings, etc. on the conductor surface, avoiding scratches on the conductor surface and improving the stability of the process.

[0016] 2. This invention utilizes the cooperation of a main control component, a self-lifting component, and a self-adjusting component. When the movable column drives the turntable to rotate, the fitting column on the turntable moves along the arc-shaped groove of the track plate, precisely driving the connecting platform to adjust the position of the placement platform. This aligns the corresponding collection cylinder (such as a deep cylinder for collecting metal fragments or a shallow cylinder for collecting insulating dust) with the trigger column. Subsequently, the trigger column of the self-lifting component rises, squeezing the blocking block inside the placement platform to unlock the collection cylinder and push it to the working position. In conjunction with the scraping block of the self-connecting component, it collects impurities in a targeted manner. It can automatically match dedicated collection units for impurities of different properties, avoiding the mixing of impurities and affecting subsequent recycling and processing, thus achieving classified collection of impurities.

[0017] 3. In this invention, the vibration component moves synchronously with the positioning bolt of the self-lifting component. When the positioning bolt moves down, it drives the lower pressure block to squeeze the lower pressure column, causing the striking block inside the vibration cylinder to stretch the tension spring and hit the cylinder wall to generate high-frequency vibration. This vibration can shake and fall the small impurities stuck on the inner wall of the collection cylinder to the bottom of the cylinder, avoiding impurities from clogging the feed window or sticking to the wall of the collection cylinder, and ensuring that the collection cylinder can continuously and effectively collect impurities.

[0018] 4. The present invention utilizes the cooperation of the main control component, the self-lifting component, and the self-connecting component. The receiving cylinder of the self-connecting component has a hollow structure and a material inlet window at the top, so that scraped impurities can fall directly into the receiving cylinder. With the limiting effect of the baffle plate, impurities will not scatter into the preheating device or the production environment, avoiding secondary adhesion of impurities to the cable or contamination of the preheater, and ensuring a clean processing environment.

[0019] 5. This invention achieves full automation of the "impurity scraping-collection-anti-clogging" process through the cooperation of the main control component, the self-lifting component, and the self-adjusting component. The servo motor of the main control component drives the transmission column and gear linkage, which synchronously drives the moving column (providing power), the trigger plate (driving the self-lifting component), and the turntable (driving the self-adjusting component). It eliminates the need for manual adjustment of the scraping position, cleaning of impurities, or adaptation of cable specifications, thus achieving automated linkage and reducing manual intervention.

[0020] 6. Through the cooperation of the main control component, the self-lifting component and the self-connecting component, the inclined spring of the self-connecting component always applies contact pressure to the scraper block. Even if there is a slight radial offset or uneven surface of the cable, the scraper block can adaptively adjust the angle through the movable bolt to ensure the fit with the outer wall of the cable and avoid the scraping of impurities.

The housing 7 is equipped with a servo motor 8. The output shaft of the servo motor 8 is fixedly connected to the transmission column 9. The outer side of the transmission column 9 is fixedly connected to the first gear 10. The outer side of the movable column 11 is fixedly connected to the second gear 50, and the second gear 50 meshes with the first gear 10. The trigger plate 14 is fixedly connected to the outer side of the movable column 11. The end of the movable column 11 away from the extension column 6 is provided with a fixing block 12. The fixing block 12 is movably connected to the movable column 11. The bottom of the fixing block 12 is fixedly connected to the placement frame 13, and the placement frame 13 is fixedly connected to the placement cylinder 2.

[0034] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, when the RF feeder cable needs to be preheated, the preheater 1 is started first. When adjustments are needed according to the specifications of the RF feeder cable, the servo motor 8 is started, and then the servo motor 8 drives the transmission column 9 to rotate. When the transmission column 9 rotates, it drives the first gear 10 to rotate. When the first gear 10 rotates, it drives the meshing second gear 50 to rotate. When the second gear 50 rotates, it drives the movable column 11 to rotate. When the movable column 11 rotates, it provides power for processing impurities.

[0035] like Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7As shown, a placement block 15 is fixedly connected inside the placement cylinder 2. The placement block 15 is equipped with a self-lifting assembly for cooperating with the main control component. The self-lifting assembly contains a lifting arm 22 and a trigger post 25. The cooperation of the lifting arm 22 and the trigger post 25 provides power for cable material connection. A positioning platform 20 is provided inside the self-lifting assembly and is fixedly connected to the inner wall of the placement cylinder 2. The positioning platform 20 consists of a square block and a cylinder. The cylindrical part of the positioning platform 20 is movably connected to the lifting arm 22. A transmission post 17 is movably connected to the placement block 15. A bonding strip 16 is fixedly connected to the outer side of the transmission post 17. A lifting strip 18 is fixedly connected to the end of the transmission post 17 away from the bonding strip 16. A connecting post 19 is fixedly connected to the lifting strip 18. A main starter strip 51 is fixedly connected to the end of the connecting post 19 away from the lifting strip 18. A fixed starting block 21 is movably connected to the strip 51. The fixed starting block 21 is H-shaped. The top of the fixed starting block 21 is movably connected to the lifting arm 22. The end of the lifting arm 22 away from the positioning table 20 is connected to the lifting frame 23, which is U-shaped. A positioning bolt 27 is fixedly connected to the trigger post 25. The lifting frame 23 is movably connected to the positioning bolt 27. A limit post 26 is fixedly connected to the bottom of the trigger post 25, and the limit post 26 is inserted into the placement frame 13. The trigger plate 14 is elliptical. The bonding strip 16 and the lifting strip 18 are distributed correspondingly with the transmission post 17 as the center. The trigger plate 14 is bonded to the bonding strip 16. When the end of the trigger plate 14 away from the movable post 11 rotates to bond with the bonding strip 16, the end of the bonding strip 16 away from the transmission post 17 rotates to the bottom, and the end of the lifting strip 18 away from the transmission post 17 rotates to the top.

[0036] like Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7As shown, when the movable column 11 rotates, it drives the trigger disc 14 to rotate. Simultaneously, the trigger disc 14 continuously presses against the bonding strip 16. When the end of the trigger disc 14 away from the movable column 11 rotates to be in contact with the bonding strip 16, the trigger disc 14 presses the end of the bonding strip 16 away from the transmission column 17 to the bottom. Then, as the bonding strip 16 rotates, it drives the lifting strip 18 away from the transmission column 17 to rotate to the top. As the lifting strip 18 lifts, it drives the connecting column 19 to rotate. As the connecting column 19 rotates, it drives the main lifting strip 51 to lift. As the main lifting strip 51 lifts, it drives the fixed lifting block 21 to move towards the top. As the fixed lifting block 21 moves, it drives the lifting arm 22 to lift along the cylindrical portion of the vibrating cylinder 29. As the lifting arm 22 lifts, it drives the lifting... The lifting frame 23 moves, and the lifting frame 23 moves the positioning bolt 27. The positioning bolt 27 moves the trigger post 25 towards the position of the top placement platform 24. When it is necessary to preheat other specifications of RF feeder cables, the end of the trigger plate 14 away from the movable post 11 rotates to a state of being in contact with the bonding strip 16. Then the bonding strip 16 drives the main start bar 51 to reset through the connecting post 19. When the main start bar 51 resets, it drives the fixed start block 21 to move towards the bottom. When the fixed start block 21 moves, it drives the lifting arm 22 to move towards the bottom. Then the lifting arm 22 drives the lifting frame 23 to move towards the bottom. When the lifting frame 23 moves, it drives the positioning bolt 27 to move, and the positioning bolt 27 drives the limit post 26 towards the bottom of the placement frame 13 through the trigger post 25.

[0037] like Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7 As shown, the placement frame 13 is equipped with a vibration assembly to prevent the collection of impurities. The vibration assembly contains a pressing block 28, which is fixedly connected to the positioning bolt 27. A vibration cylinder 29 is fixedly connected to the top of the placement frame 13. A striking block 31 is provided inside the vibration cylinder 29. The two ends of the striking block 31 are fixedly connected to the inner wall of the vibration cylinder 29 and the tension spring 32, respectively. The tension spring 32 is located inside the vibration cylinder 29. When the pressing block 28 moves towards the bottom, the pressing block 28 is in contact with the top of the pressing column 30. When the pressing block 28 moves towards the bottom to the maximum distance, the tension spring 32 is in contact with the bottom of the vibration cylinder 29.

[0038] like Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7As shown, when the positioning bolt 27 moves towards the bottom, the positioning bolt 27 drives the lower pressure block 28 to move towards the top of the lower pressure column 30. Then, the lower pressure block 28 squeezes the lower pressure column 30 during its movement. After being squeezed by the lower pressure block 28, the lower pressure column 30 moves towards the inside of the vibrating cylinder 29. During its movement, the lower pressure column 30 drives the striking block 31 to stretch, and the lower pressure column 30 drives the tension spring 32 to move towards the bottom. When the lower pressure block 28 moves to the maximum distance towards the bottom, the lower pressure column 30 drives the tension spring 32 to strike the vibrating cylinder 29 and generate vibration. The generated vibration causes the impurities stuck on the inner wall of the storage cylinder 33 to vibrate and fall into the bottom of the storage cylinder 33.

[0039] like Figure 6 , Figure 7 , Figure 8 , Figure 9 and Figure 10 As shown, the movable column 11 is equipped with a self-adjusting component for cooperating with the self-lifting assembly. The self-adjusting component contains a track plate 36 and a turntable 37. The track plate 36 and turntable 37 work together to adjust the position according to the nature of the impurities. The self-adjusting component also contains a connecting platform 35, which is movably connected to the placement frame 13. Four track plates 36 are fixedly connected to the outer side of the connecting platform 35. The turntable 37 is fixedly connected to the end of the movable column 11 away from the second gear 50. A fitting column 38 is fixedly connected to the outer side of the turntable 37. Four placement platforms 24 are fixedly connected to the top of the connecting platform 35. Each placement platform 24 has two fixedly connected limit cylinders 39. Each limit cylinder 39 contains a spring 40. The two ends of each spring 40 are fixedly connected to the inner wall of the corresponding limit cylinder 39 and a blocking block 41, respectively. The blocking block 41 consists of an inclined block and a disc. Each placement platform 24 has two movable slots for placing the blocking blocks 41. The inclined block 41... The inclined blocks are all inserted into the movable slots of the placement platform 24. Each placement platform 24 has a storage cylinder 33 inserted into it. The bottom of each storage cylinder 33 is provided with a stop groove for placing the inclined block portion of the corresponding blocking block 41. The inclined block portion of each blocking block 41 is inserted into the corresponding stop groove of the storage cylinder 33. The top of the blocking plate 4 is provided with a circular groove for placing the storage cylinder 33. When the trigger pin 25 enters the interior of the placement platform 24, the trigger pin 25 pushes the corresponding storage cylinder 33 to rise to the desired height. In the circular groove of the baffle plate 4, each track piece 36 is an arc-shaped spherical piece. The top of each track piece 36 is provided with a semi-circular groove for placing the turntable 37, and there is a placement groove for placing the bonding column 38 between every two track pieces 36. When the bonding column 38 rotates to the position corresponding to the placement groove between the two track pieces 36, the bonding column 38 enters the placement groove between the two track pieces 36, and the position of each track piece 36 corresponds to the placement platform 24 on the outside of the rotating column 34.

[0040] like Figure 6 , Figure 7 , Figure 8 , Figure 9 and Figure 10 As shown, when the trigger post 25 rises toward the position of the corresponding placement platform 24, the trigger post 25 enters the interior of the corresponding placement platform 24, and then the trigger post 25 comes into contact with the corresponding blocking block 41. The trigger post 25 then presses the two blocking blocks 41 to move toward the position of the limiting cylinder 39. When the blocking blocks 41 move, they drive the spring 40 to compress. As a result, the two blocking blocks 41 release the connection with the blocking groove of the storage cylinder 33 while moving. Then the trigger post 25 drives the storage cylinder 33 to move toward the top. Then the trigger post 25 pushes the corresponding storage cylinder 33 to rise into the circular groove of the blocking plate 4.

[0041] like Figure 6 , Figure 7 , Figure 8 , Figure 9 and Figure 10 As shown, each storage cylinder 33 has a self-connecting assembly at its top for automatically connecting cable materials. The self-connecting assembly contains a recessed block 42, which is fixedly connected to the top of the corresponding storage cylinder 33. Each storage cylinder 33 is hollow, and each storage cylinder 33 has an inlet window at its top for collecting impurities. The recessed block 42 has a slot for placing a locking block 43, which engages in the slot. Two extension platforms 44 are fixedly connected to the outer side of the locking block 43. 3 is fixedly connected to a movable bolt 46. Two scraper blocks 47 are movably connected to the outer side of the movable bolt 46. Each scraper block 47 is semi-arc-shaped. A fitting piece 48 is fixedly connected to the top of each scraper block 47. A scraper blade 49 is fixedly connected to the top of the movable bolt 46. The scraper blade 49 and the two scraper blocks 47 form a circle. A inclined spring 45 is fixedly connected to the top of each extension platform 44. The end of each inclined spring 45 away from the corresponding extension platform 44 is fixedly connected to the corresponding scraper block 47.

[0042] like Figure 6 , Figure 7 , Figure 8 , Figure 9 and Figure 10As shown, when the storage cylinder 33 is lifted, the corresponding storage cylinder 33 drives the groove block 42 to lift. When the groove block 42 is lifted, it drives the locking block 43 to lift. When the locking block 43 moves, it drives the movable bolt 46 to move towards the RF feed cable. Then, when the two bonding pieces 48 contact the RF feed cable, the semi-circular positions of the two bonding pieces 48 are squeezed by the RF feed cable. The squeezed bonding pieces 48 drive the corresponding scraper block 47 to expand and rotate along the movable bolt 46. When the scraper block 47 rotates, it drives the inclined spring 45 to compress. When the RF feed cable is completely inserted into the interior of the scraper block 47, the compressed inclined spring 45 rebounds and drives the two scraper blocks 47 to return to the bonding state. Then, when the RF feed cable moves, the scraper 49 and the scraper block 47 cooperate to scrape off the impurities on the RF feed cable. The scraped impurities enter the interior of the storage cylinder 33 from the corresponding storage cylinder 33 inlet.

[0043] Working principle:

[0044] First step, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, when the RF feeder cable needs to be preheated, the preheater 1 is started first. When it needs to be adjusted according to the specifications of the RF feeder cable, the servo motor 8 is started. Then the servo motor 8 drives the transmission column 9 to rotate. When the transmission column 9 rotates, it drives the first gear 10 to rotate. When the first gear 10 rotates, it drives the meshing second gear 50 to rotate. When the second gear 50 rotates, it drives the movable column 11 to rotate. When the movable column 11 rotates, it provides power for processing impurities.

[0045] The second step, as Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7As shown, when the movable column 11 rotates, it drives the trigger disc 14 to rotate. Simultaneously, the trigger disc 14 continuously presses against the bonding strip 16. When the end of the trigger disc 14 away from the movable column 11 rotates to be in contact with the bonding strip 16, the trigger disc 14 presses the end of the bonding strip 16 away from the transmission column 17 to the bottom. Then, as the bonding strip 16 rotates, it drives the lifting strip 18 away from the transmission column 17 to rotate to the top. As the lifting strip 18 lifts, it drives the connecting column 19 to rotate. As the connecting column 19 rotates, it drives the main lifting strip 51 to lift. As the main lifting strip 51 lifts, it drives the fixed lifting block 21 to move towards the top. As the fixed lifting block 21 moves, it drives the lifting arm 22 to lift along the cylindrical portion of the vibrating cylinder 29. As the lifting arm 22 lifts, it drives the lifting... The lifting frame 23 moves, and the lifting frame 23 moves the positioning bolt 27. The positioning bolt 27 moves the trigger post 25 towards the position of the top placement platform 24. When it is necessary to preheat the RF feeder cable of other specifications, the end of the trigger plate 14 away from the movable post 11 rotates to the state of being in contact with the bonding strip 16. Then the bonding strip 16 drives the main start bar 51 to reset through the connecting post 19. When the main start bar 51 resets, it drives the fixed start block 21 to move towards the bottom. When the fixed start block 21 moves, it drives the lifting arm 22 to move towards the bottom. Then the lifting arm 22 drives the lifting frame 23 to move towards the bottom. When the lifting frame 23 moves, it drives the positioning bolt 27 to move. And the positioning bolt 27 drives the limit post 26 to move towards the bottom of the placement frame 13 through the trigger post 25.

[0046] The third step, as Figure 6 , Figure 7 , Figure 8 , Figure 9 and Figure 10 As shown, when the trigger post 25 rises toward the position of the corresponding placement platform 24, the trigger post 25 enters the interior of the corresponding placement platform 24, and then the trigger post 25 comes into contact with the corresponding blocking block 41. The trigger post 25 then presses the two blocking blocks 41 to move toward the position of the limiting cylinder 39. When the blocking blocks 41 move, they drive the spring 40 to compress. As a result, the two blocking blocks 41 release the connection with the blocking groove of the storage cylinder 33 while moving. Then the trigger post 25 drives the storage cylinder 33 to move toward the top. Then the trigger post 25 pushes the corresponding storage cylinder 33 to rise into the circular groove of the blocking plate 4.

[0047] Step four, as Figure 6 , Figure 7 , Figure 8 , Figure 9 and Figure 10As shown, when the storage cylinder 33 is lifted, the corresponding storage cylinder 33 drives the groove block 42 to lift. When the groove block 42 is lifted, it drives the locking block 43 to lift. When the locking block 43 moves, it drives the movable bolt 46 to move towards the RF feed cable. Then, when the two bonding pieces 48 contact the RF feed cable, the semi-circular position of the two bonding pieces 48 is squeezed by the RF feed cable. The squeezed bonding pieces 48 drive the corresponding scraper block 47 to expand and rotate along the movable bolt 46. When the scraper block 47 rotates, it drives the inclined spring 45 to compress. When the RF feed cable is completely inserted into the interior of the scraper block 47, the compressed inclined spring 45 rebounds and drives the two scraper blocks 47 to return to the bonding state. Then, when the RF feed cable moves, the scraper 49 and the scraper block 47 cooperate to scrape off the impurities on the RF feed cable. The scraped impurities enter the interior of the storage cylinder 33 from the corresponding storage cylinder 33 inlet.

[0048] Fifth step, as Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7 As shown, when the positioning bolt 27 moves towards the bottom, the positioning bolt 27 drives the lower pressure block 28 to move towards the top of the lower pressure column 30. Then, the lower pressure block 28 squeezes the lower pressure column 30 during its movement. After being squeezed by the lower pressure block 28, the lower pressure column 30 moves towards the inside of the vibrating cylinder 29. During its movement, the lower pressure column 30 drives the striking block 31 to stretch, and the lower pressure column 30 drives the tension spring 32 to move towards the bottom. When the lower pressure block 28 moves to the maximum distance towards the bottom, the lower pressure column 30 drives the tension spring 32 to strike the vibrating cylinder 29 and generate vibration. The generated vibration causes the impurities stuck on the inner wall of the storage cylinder 33 to vibrate and fall into the bottom of the storage cylinder 33.

Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
