Description

Technical Field

[0001] This invention relates to the field of regulator processing technology, specifically to a regulator surface plasma roughening treatment device. Background Technology

[0002] The ink regulator is a key component in various writing instruments, primarily used to control ink flow, prevent leakage, and ensure smooth writing. For example, in everyday direct-liquid rollerball pens, the core component is the direct-liquid regulator, which uses optimized structural design to control air pressure release and ensure stable ink flow. During the manufacturing process, to ensure surface cleanliness and activation, and to optimize the precision structure, high-energy particles from plasma are typically used to remove nanoscale oil, oxides, and processing residues from the ink refill surface, ensuring the cleanliness of the ink flow channels. Furthermore, plasma bombardment introduces polar groups (such as hydroxyl and carboxyl groups) onto the material surface, making the hydrophobic ink refill surface hydrophilic and improving ink wettability and adhesion. For instance, the surface energy of PTFE ink refills increases from 18 mN / m to over 50 mN / m after treatment. Therefore, plasma surface treatment equipment is required to roughen the regulator during its production.

[0003] In related technologies, to prevent the material cylinder in plasma surface treatment equipment from driving the ion generator to rotate synchronously and causing unstable discharge, for example, the prior art patent with publication number CN116631834B provides a surface modification treatment device and modification treatment method. This device arranges the plasma source device outside the vacuum chamber, and after the plasma source device excites plasma, the plasma is transported to the material cylinder inside the vacuum chamber, where it reacts with the surface of the material to be treated. By separating the plasma excitation zone and the material treatment zone, the plasma load is not affected by the processed material or its movement, achieving stable discharge and thus improving the quality of material treatment. Moreover, only the material cylinder is a rotating structure, while the vacuum chamber and the plasma excitation device are fixed structures. The overall structure is simple, which can reduce the precision of components and installation requirements. Furthermore, both the vacuum chamber and the material cylinder are equipped with detachable end caps, and the material cylinder can also be disassembled and removed from the vacuum chamber, facilitating equipment maintenance and repair.

[0004] Although the existing technical solution described above can prevent the discharge instability caused by the synchronous rotation of the ion generator by using a separately rotating material cylinder structure, when the regulator loads or unloads materials inside the material cylinder, the chamber door needs to be opened and the material cylinder removed separately from the chamber. Then, the regulator inside the material cylinder needs to be emptied out. When removing and installing the material cylinder, the toothed ring on the outside of the material cylinder and the drive gear restrict the material cylinder to be picked up and placed along the axial direction. In particular, when installing the material cylinder, the toothed ring on the outside of the material cylinder needs to be aligned with the drive gear for installation, which makes the loading and unloading operation of the regulator inside the material cylinder inconvenient. Summary of the Invention

[0005] To address one of the shortcomings of existing technologies, this invention provides a plasma roughening treatment device for the surface of a regulator, which solves the problem of inconvenient loading and unloading operations of the regulator inside the material cylinder during the plasma roughening treatment process.

[0012] Preferably, the baffle is disposed between the material cylinder and the linkage sleeve, and the baffle further includes: Sliding pin B is fixedly installed on the outside of the baffle, and sliding pin B extends toward the linkage sleeve; The linkage sleeve also includes: The guide groove is an arc-shaped groove corresponding to the sliding pin B; the baffle is linked with the linkage sleeve through the sliding pin B and the guide groove.

[0013] Preferably, the driving component includes: A translation drive assembly is provided to drive the material cylinder and the linkage sleeve to move, and the translation drive assembly is located below the linkage sleeve. The rotation drive assembly, linked with the material cylinder, can drive the material cylinder to rotate around its own axis as a reference axis; A limiting component is installed inside the vacuum furnace, which can limit the horizontal displacement of the material cylinder.

[0018] Compared with the existing technology, this solution has the following advantages: By setting a translation drive component to drive the material cylinder and the linkage sleeve to move horizontally, the material cylinder can be moved between the main feed inlet and the guide pipe. This allows the material cylinder to be separated from the guide pipe when loading, unloading, or disassembling below the main feed inlet. Furthermore, under the drive of the translation drive component, when the material cylinder is located below the main feed inlet or outside the guide pipe, the linkage sleeve can be driven to slide axially on the outside of the material cylinder. This allows the baffle on the outside of the material cylinder to be in the open and closed states when it is below the main feed inlet and outside the guide pipe, respectively, to ensure the smooth operation of loading, unloading, and plasma roughing.

Detailed Implementation

[0021] The technical solutions of this application will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0022] Please see Figures 1-3 This application provides the following technical solutions: A device for plasma roughening treatment of regulator surface includes a vacuum furnace 1, a plasma generator 2, a material cylinder 3, a linkage sleeve 4, a translation drive assembly 5, and a rotation drive assembly 6.

[0023] The vacuum furnace 1 is a horizontally positioned furnace body with an internal cavity. Its long axis is horizontal. A main feed inlet 11 is located on one side of the top of the vacuum furnace 1, and a main discharge outlet 12 is located at the bottom of the vacuum furnace 1 corresponding to the main feed inlet 11. The main feed inlet 11 and the main discharge outlet 12 maintain a seal within the vacuum furnace 1 during the plasma roughening treatment of the regulator surface. A top sealing cover 13 and a bottom sealing cover 14 are fixedly installed on the outer sides of the top and bottom of the vacuum furnace 1, respectively. The top sealing cover 13 and the bottom sealing cover 14 are located outside the main feed inlet 11 and the main discharge outlet 12, respectively. A sealing door frame 15 is fixedly installed on the outer side of the vacuum furnace 1 corresponding to the top sealing cover 13 and the bottom sealing cover 14. A door panel 16 is detachably installed inside the sealing door frame 15 for sealing the top sealing cover 13 and the bottom sealing cover 14. A vacuum pump 17 is also fixedly installed on the top of the vacuum furnace 1 for evacuating the interior of the vacuum furnace 1. A display controller 18 is also fixedly installed on the vacuum furnace 1 for displaying processing parameters.

[0024] The plasma generator 2 is fixedly installed on the side of the vacuum furnace 1 away from the main feed inlet 11, and is fixedly connected to the side wall of the vacuum furnace 1. A guide pipe 21 is fixedly installed at the output end of the plasma generator 2, and a split pipe 22 is fixedly installed at the other end of the guide pipe 21. The split pipe 22 is horizontally arranged and coaxial with the material cylinder 3. The split pipe 22 extends into the interior of the material cylinder 3. A distribution hole group 23 is provided on the side wall of the lower half of the split pipe 22. The distribution hole group 23 includes a rectangular array of distribution holes for uniformly distributing the plasma release.

[0025] The material cylinder 3 has an internal cavity for holding the regulator. The material cylinder 3 is installed inside the vacuum furnace 1. A material inlet 31 is provided on the cylinder wall of the material cylinder 3. The regulator can fall into the material cylinder 3 through the main feed inlet 11 and the material inlet 31. Two baffles 32 are symmetrically slidably arranged on the outer side of the cylinder wall of the material cylinder 3. The baffles 32 can be symmetrically slid open and close to control the opening and closing of the material inlet 31.

[0026] The linkage sleeve 4 is slidably disposed on the outside of the material cylinder 3, and the sliding direction of the linkage sleeve 4 is horizontal. The linkage sleeve 4 is linked with the two baffles 32 to drive the two baffles 32 to move closer or further apart.

[0027] The translation drive component 5 is located below the material cylinder 3 and the linkage sleeve 4, and is linked with the material cylinder 3 and the linkage sleeve 4 to drive the material cylinder 3 and the linkage sleeve 4 to move horizontally.

[0028] The rotation drive assembly 6 is linked with the material cylinder 3 to drive the material cylinder 3 to rotate.

[0029] When the translation drive assembly 5 drives the material cylinder 3 and the linkage sleeve 4 to be below the main feed inlet 11, it automatically triggers the material cylinder 3 and the linkage sleeve 4 to slide relative to each other axially, thereby driving the baffle 32 to automatically open the material inlet 31. During the roughening treatment of the regulator, the translation drive assembly 5 drives the material cylinder 3 and the linkage sleeve 4 to move below the main feed inlet 11 inside the vacuum furnace 1. After the material cylinder 3 is below the main feed inlet 11, the translation drive assembly 5 continues to drive the linkage sleeve 4 to slide relative to the material cylinder 3 axially, causing the linkage sleeve 4 to open the symmetrically arranged baffles 32 on the outside of the material cylinder 3 through axial sliding. Under the drive of the rotation drive assembly 6, the material cylinder 3 rotates so that the outer material inlet 31 faces upwards. This allows the regulator to be added into the material cylinder 3 through the main feed inlet 11 after the baffle 32 slides to open the material inlet 31. After the material cylinder 3 completes the feeding of the regulator, the translation drive assembly 5 pushes the material cylinder 3 and the linkage sleeve 4 to move towards the side closer to the plasma generator 2. This allows the material cylinder 3 to connect with the guide pipe 21 at the output end of the plasma generator 2 after feeding, so that the diversion pipe 22 at the end of the guide pipe 21 fully extends into the interior of the material cylinder 3. After the material cylinder 3 moves into place, the linkage sleeve 4 is driven by the translation drive assembly 5 to slide and reset axially, thereby driving the symmetrically arranged baffle 32 to slide and close the material port 31. Then, the door plate 16 is sealed and installed inside the sealing door frame 15 (the sealing installation of the door plate 16 is a common existing technology and will not be described in detail here) to seal the vacuum furnace 1. After the vacuum pump 17 is started to evacuate the vacuum furnace 1, the plasma generator 2 is started to generate plasma. The plasma enters the interior of the diversion pipe 22 through the guide pipe 21 and finally enters the interior of the material cylinder 3 through the distribution hole group 23 on the lower half of the outer side of the diversion pipe 22, making full contact with the regulator.

[0030] During the roughening process, the rotation drive assembly 6 drives the material cylinder 3 to rotate continuously, keeping the regulator inside the material cylinder 3 turning to ensure the uniformity of the roughening process. After the regulator finishes processing, the translation drive assembly 5 drives the material cylinder 3 and the linkage sleeve 4 to move below the main feed port 11, so that the material cylinder 3 is driven by external force to move the material port 31 to the bottom. Then, the translation drive assembly 5 continues to drive the linkage sleeve 4 to slide axially on the outside of the material cylinder 3, so that the linkage sleeve 4 drives the baffle 32 to open the bottom material port 31, so that the processed regulator can be automatically discharged. The regulator will be discharged from the vacuum furnace 1 through the main discharge port 12. After the door panel 16 is disassembled, the loading and unloading operations can be easily carried out through the main feed port 11 and the main discharge port 12.

[0031] Based on the above implementation plan, see Figure 6 To ensure a stable connection between the baffle 32 and the material cylinder 3, arc-shaped limiting rings 35 are fixedly installed on the outer periphery of both ends of the material cylinder 3. The limiting ring 35 is an arc-shaped ring. Two guide holes 351 are symmetrically opened on the ring body of the limiting ring 35, and the guide holes 351 are arc holes. In addition, sliding grooves 352 are respectively provided on the two outer sections of the limiting ring 35. A slide rail A36 is fixedly installed on the outer side of the limiting ring 35 near the plasma generator 2, corresponding to the slide groove 352. The sliding direction of the slide rail A36 is parallel to the axial direction of the material cylinder 3.

[0032] Ridge plates B38 are uniformly fixedly arranged inside the material cylinder 3; sliding pins A321 are fixedly arranged on both sides of the baffle 32, and sliding pins A321 are slidably arranged inside the guide hole 351. Ridge plates A324 are fixedly arranged on one side of the baffle 32 corresponding to the inside of the material cylinder 3. Ridge plates A324 and ridge plates B38 are equally spaced and used for stirring regulators; the baffle 32 can slide and cooperate with the limiting ring 35 through the sliding pins A321 on both sides to limit the sliding direction and angle of the baffle 32, and the ridge plates A324 cooperate with the ridge plates B38 inside the material cylinder 3 to ensure the stirring effect of the regulator. Furthermore, a sliding pin B323 is fixedly installed on the outer side of the baffle 32 via a boss 322, and the sliding pin B323 is arranged radially along the material cylinder 3; a guide groove 41 is provided on the side wall of the linkage sleeve 4 corresponding to the sliding pin B323, and the guide groove 41 is inclined in the circumferential direction; a slider 42 is fixedly installed on the inner side of the linkage sleeve 4 corresponding to the sliding groove 352, and the two sliders 42 are respectively axially slidably arranged with the sliding groove 352 and the slide rail A36; so that when the linkage sleeve 4 slides relative to the material cylinder 3, the linkage sleeve 4 ensures the stability of axial sliding through the cooperation of the inner slider 42 with the sliding groove 352 and the slide rail A36, and can make the material cylinder 3 drive the linkage sleeve 4 to rotate synchronously; and during the sliding process, the linkage sleeve 4 can drive the sliding pin B323 on the outer side of the baffle 32 to rotate around the axis of the material cylinder 3 through the guide groove 41 inclined on the side wall, and then drive the baffle 32 to rotate around the axis on the outer side of the material cylinder 3 through the sliding pin B323, so as to control the opening and closing action of the baffle 32 on the material port 31.

[0033] Based on the above implementation plan, see Figures 6 to 8 To ensure stable rotation of the material cylinder 3 and the linkage sleeve 4, connecting rings 43 are fixedly installed on the outer sides of both ends of the linkage sleeve 4. The connecting rings 43 are circular bearing rings, including an inner ring and an outer ring that can rotate relative to each other. The inner ring of the connecting ring 43 is fixedly connected to the material cylinder 3. A groove 44 is formed on the circumference of the outer ring of the connecting ring 43.

[0034] The translation drive assembly 5 includes a slide table 54, with a vertical plate 55 fixedly mounted at each end of the slide table 54. Two rotating shafts 56 are rotatably mounted on the vertical plates 55, and the two rotating shafts 56 are symmetrically arranged on the outer sides of the material cylinder 3. Each end of the rotating shaft 56 is equipped with a support wheel 57. The longitudinal section of the outer periphery of the support wheel 57 is an isosceles trapezoidal shape, and the thickness of the support wheel 57 matches the width of the groove 44.

[0035] The connecting ring 43 is supported by the support wheel 57 to ensure the stability of the linkage sleeve 4. The linkage sleeve 4 is connected to the material cylinder 3 via the slider 42, ensuring the stability of the rotation of the material cylinder 3. The support wheel 57 is also designed to cooperate with the groove 44, facilitating the disassembly and maintenance of the material cylinder 3 and the linkage sleeve 4 as a whole. During installation, the isosceles trapezoidal shape of the support wheel 57 facilitates insertion and engagement with the groove 44. After installation, the two sides of the support wheel 57 fit snugly against the inner side of the groove 44, preventing axial misalignment between the groove 44 and the support wheel 57. When the material cylinder 3 drives the linkage sleeve 4 to rotate, it rotates within the inner ring of the connecting ring 43, preventing the groove 44 from rotating and causing wear on the support wheel 57. With the cooperation of the support wheel 57 and the groove 44, the horizontal movement of the slide table 54 drives the connecting ring 43, the linkage sleeve 4, and the material cylinder 3 to move synchronously, achieving translation of the material cylinder 3 between the main feed inlet 11 and the guide pipe 21.

[0036] Based on the above implementation scheme, a horizontal base plate 51 is fixedly installed at the bottom of the vacuum furnace 1. A discharge port 52 is opened on the plate body corresponding to the main discharge port 12. A horizontal slide rail B53 is installed on the upper side of the base plate 51. The slide table 54 and the slide rail B53 are horizontally slidably connected. Two lead screw sleeves 59 are fixedly installed on the slide table 54.

[0037] Two lead screws 58 are symmetrically rotated inside the vacuum furnace 1, and the lead screws 58 and lead screw sleeves 59 are threadedly connected. A three-axis gearbox 510 and a motor B for driving the lead screws 58 to rotate are fixedly installed on the outside of the vacuum furnace 1.

[0038] When it is necessary to move the material cylinder 3 and the linkage sleeve 4, the starting motor B and the three-axis gearbox 510 drive the two lead screws 58 to rotate. The lead screws 58 are linked with the lead screw sleeve 59, thereby driving the slide table 54 to move horizontally along the slide rail B53, so that the slide table 54 drives the vertical plate 55 to move horizontally inside the vacuum furnace 1. Then, the support wheels 57 on the slide table 54 drive the linkage sleeve 4 and the material cylinder 3 to move horizontally. The motor B is set on the outside of the vacuum furnace 1 to isolate it from the vacuum treatment space inside the vacuum furnace 1, ensuring the stability of the equipment operation.

[0039] Based on the above implementation scheme, a constriction tube 33 is provided on the side of the material cylinder 3 near the guide tube 21, and the guide tube 21 is sleeved inside the constriction tube 33. A trapezoidal column 34 is coaxially fixed at the other end of the material cylinder 3, and the trapezoidal column 34 is connected to the rotation drive assembly 6.

[0040] A vertical fixing plate 511 is provided at the end of the slide table 54 away from the plasma generator 2. The fixing plate 511 has shaft holes A513 and B515 on its inner side. A mounting port 514 is provided on the fixing plate 511 corresponding to the top of the trapezoidal column 34. The mounting port 514 is connected to the shaft hole A513.

[0041] The rotation drive assembly 6 includes a drive disk 61, which is rotatably disposed within the shaft hole A513. A mounting groove 62 is formed on the drive disk 61 corresponding to the trapezoidal column 34. The mounting groove 62 is an open groove, with a notch formed on the peripheral side of the drive disk 61 corresponding to the trapezoidal column 34 for mounting the trapezoidal column 34. The width of the top of the trapezoidal column 34 is smaller than the diameter of the drive disk 61.

[0042] A gear ring 63 is fixedly mounted on the outer side of the drive disc 61. The gear ring 63 is not circular and has a notch in its corresponding mounting groove 62. Drive wheels 64 are symmetrically arranged on both outer sides of the gear ring 63. The drive wheels 64 are rotatably connected to the fixing plate 511 through the shaft hole B515, and the drive wheels 64 mesh with the gear ring 63.

[0043] When installing and removing the material cylinder 3, the notch on the drive disc 61 is oriented upwards, and the notch on the drive disc 61 is vertically aligned with the mounting opening 514 on the top of the fixing plate 511. This facilitates placing the trapezoidal column 34, which moves the material cylinder 3, inside the mounting groove 62 from top to bottom or removing it in the opposite direction. At this time, the narrow face of the trapezoidal column 34 is located at the bottom, and the material cylinder 3 can be axially positioned through the inclined surface on the outer side of the trapezoidal column 34. When the drive wheel 64 installed on the outer side of the fixing plate 511 corresponding to the shaft hole B515 is driven to rotate in the same direction by external force, the toothed ring 63 located between the two drive wheels 64 drives the drive disc 61 to rotate. When the notch of the drive disc 61 rotates to the outside of one of the drive wheels 64, the other drive wheel 64 can continue to drive the drive disc 61 to rotate, so as to ensure that the drive disc 61 can rotate continuously while facilitating the assembly of the material cylinder 3.

[0044] Based on the above implementation scheme, two bearing plates 512 are provided on the upper side of the fixing plate 511. Both bearing plates 512 are inclined and their upper ends are far apart from each other.

[0045] The rotation drive assembly 6 also includes sprockets A65 coaxially fixed outside the drive wheel 64. Sprockets A65 are linked to sprockets B67 via chains 66. Sprockets B67 are rotatably connected to bearing plates 512 via rotating bushings 68. Inside the vacuum furnace 1, corresponding to the two sprockets B67, there are rotatably mounted spindles 69, which slide horizontally with bushings 69 and bushings 68. At the outer end of each spindle 69 located outside the vacuum furnace 1, a toothed pulley A610 is coaxially fixed. The toothed pulleys A610 are linked to toothed pulleys B612 via transmission belts 611. Toothed pulleys B612 are rotatably mounted outside the vacuum furnace 1. A motor A613 for driving the toothed pulleys B612 is fixedly mounted outside the vacuum furnace 1. The distance between the two spindles 69 is greater than the outer diameter of the connecting ring 43.

[0046] During the regulator operation, the motor A613 on the outside of the vacuum furnace 1 is started, driving the toothed pulley B612 to rotate. The rotation of pulley B612 drives the toothed pulley A610 to rotate via the transmission belt 611. The rotation of pulley A610 then drives the coaxially fixed spindle 69 to rotate synchronously. Since the spindle 69 and sprocket B67 are axially slidingly connected via bushing 68, and sprocket B67 is linked to sprocket A65 via chain 66, and sprocket A65 is coaxially fixed on the outside of drive wheel 64, the rotation of spindle 69 drives sprocket B67 to rotate, which in turn drives sprocket A65 and drive wheel 64 to perform corresponding actions, causing drive wheel 64 to drive drive disc 61 to rotate. This structure isolates the power source from the vacuum processing space inside the vacuum furnace 1, ensuring that each component can operate stably according to design requirements when the equipment is processing the regulator. At the same time, the design of the tops of the two bearing plates 512 being far apart from each other and the distance between the two flower shafts 69 being greater than the outer diameter of the connecting ring 43 also provides a reasonable spatial layout and safety guarantee for the operation of the entire equipment, allowing the material cylinder 3 and the linkage sleeve 4 to be operated from between the two flower shafts 69 when disassembling and installing.

[0047] Based on the above implementation scheme, in order to enable the material cylinder 3 and the linkage sleeve 4 to slide relative to each other after moving below the main feed inlet 11 and outside the guide pipe 21, thereby driving the baffle 32, a limit plate 37 is fixedly provided at the ends of the material cylinder 3's closing pipe 33 and the trapezoidal column 34 that are far apart from each other.

[0048] This scheme also includes two sets of limiting components 7, which are fixedly installed inside the vacuum furnace 1 and outside the guide pipe 21, respectively. Each limiting component 7 includes a fixed plate 71 fixedly installed with the vacuum furnace 1 and the guide pipe 21. A push rod 72 is arranged in a ring array on the side of the fixed plate 71 near the limiting plate 37, and a ball bearing 73 is provided at the end of each push rod 72 near the limiting plate 37. A ball groove 371 is opened on the side of the limiting plate 37 that is far apart from each other, and the ball bearing 73 is aligned with the ball groove 371 in the axial direction.

[0049] When the material cylinder 3 and the linkage sleeve 4 are located below the main feed inlet 11 or outside the guide pipe 21, in these two states, the limiting plates 37 at both ends of the closing pipe 33 and the trapezoidal column 34 are respectively pressed against the limiting components 7 inside the vacuum furnace 1 and the limiting components 7 outside the guide pipe 21, preventing the material cylinder 3 from moving further. The translation drive component 5 continues to drive the linkage sleeve 4 to slide axially outside the material cylinder 3, thereby achieving the driving effect on the baffle 32, so as to open and close the material inlet 31 before and after feeding.

[0050] In the open state of the material inlet 31, in order to facilitate loading and unloading by adjusting the position of the material inlet 31 and to ensure stable rotation of the material cylinder 3 when the material inlet 31 is closed, when the limiting component 7 and the limiting plate 37 are pressed together, the ball 73 at the end of the push rod 72 is located inside the ball groove 371. The push rod 72 separates the fixed plate 71 and the limiting plate 37, so that the material cylinder 3 can drive the limiting plate 37 to rotate.

[0051] The internal space of the material cylinder 3 is connected to the inside of the vacuum furnace 1. By drawing a vacuum inside the vacuum furnace 1, the material cylinder 3 can be placed under vacuum conditions to perform plasma roughening treatment on the regulator.

[0052] This solution uses a linkage mechanism to drive the relevant components of the material cylinder 3. It is highly practical for small parts like the regulator. The overall manufacturing cost of the equipment is low, and the debugging is not difficult. Multiple devices can be set up to coarse the regulator separately to ensure the good quality of the regulator coarsening process.

[0053] The principle and advantages of the plasma roughening treatment equipment for the regulator surface in this solution: First, during feeding, the starter motor B drives the two lead screws 58 at the drive end of the three-axis gearbox 510 to rotate simultaneously. The lead screws 58 drive the slide table 54 to move horizontally inside the vacuum furnace 1, which in turn drives the linkage sleeve 4 and the material cylinder 3 to move below the main feed inlet 11 inside the vacuum furnace 1. When the material cylinder 3 is below the main feed inlet 11, the limiting plate 37 at the end of the trapezoidal column 34 abuts against the limiting component 7 inside the vacuum furnace 1. As the translation drive component 5 continues to drive the linkage sleeve 4 to move, the linkage sleeve 4 and the material cylinder 3 slide relative to each other in the axial direction. The sliding of the linkage sleeve 4 drives the baffle 32 to open. At this time, the material cylinder 3 rotates under the drive of the rotation drive component 6, and the material inlet 31 is located on the upper side, so that after the baffle 32 is opened, the regulator to be processed can be added into the material cylinder 3 through the main feed inlet 11. After the regulator loads the material, the translation drive assembly 5 pushes the material cylinder 3 and the linkage sleeve 4 to move closer to the plasma generator 2, causing the diversion pipe 22 at the end of the guide pipe 21 to extend into the interior of the material cylinder 3. After the material cylinder 3 is in place, the limiting plate 37 on the outside of the closing pipe 33 abuts against the limiting assembly 7 on the outside of the guide pipe 21. Finally, driven by the translation drive assembly 5, the linkage sleeve 4 slides axially back to its original position, and the baffle 32 slides to close the material inlet 31. Then, the door plate 16 is sealed and installed inside the sealing door frame 15. The vacuum pump 17 is started to evacuate the vacuum furnace 1, and the plasma generator 2 is started to generate plasma. The plasma enters the interior of the diversion pipe 22 through the guide pipe 21, and finally enters the interior of the material cylinder 3 through the distribution hole group 23 on the lower half of the outer side of the diversion pipe 22, making full contact with the regulator.

[0054] During processing, motor A613 on the outside of vacuum furnace 1 is started. Motor A613 drives drive disc 61 to rotate via drive wheel 64. When the notch of drive disc 61 rotates to the outside of one of drive wheels 64, the other drive wheel 64 can continue to drive drive disc 61 to rotate, ensuring that drive disc 61 can rotate continuously while facilitating assembly of material cylinder 3. Furthermore, when material cylinder 3 and linkage sleeve 4 move horizontally, sprocket B67 can be driven to slide axially outside of spindle 69 via fixing plate 511 and bearing plate 512, so that material cylinder 3 can be driven to rotate by motor A613 both below main feed port 11 and outside guide pipe 21, facilitating adjustment of the position of material port 31.

[0055] During material feeding, the material cylinder 3 and the linkage sleeve 4 are moved to the bottom of the main feed port 11 by the translation drive component 5. The motor A613 drives the material cylinder 3 to rotate, causing the material port 31 to be located at the bottom. Then, the translation drive component 5 continues to drive the linkage sleeve 4 to slide axially on the outside of the material cylinder 3, and the drive baffle 32 opens the bottom material port 31 to facilitate the automatic feeding of the processed regulator. The regulator will be discharged from the vacuum furnace 1 through the main discharge port 12. After feeding, the material cylinder 3 is rotated by the motor A613 to adjust the material port 31 to the upper side. After the door panel 16 is disassembled, the loading and unloading operations can be facilitated through the main feed port 11 and the main discharge port 12.

[0056] The material cylinder 3 and the linkage sleeve 4 are moved horizontally by the translation drive component 5, so that the material cylinder 3 can move between the main feed port 11 and the guide pipe 21. This allows the material cylinder 3 to be separated from the guide pipe 21 when loading, unloading, or disassembling below the main feed port 11. Under the drive of the translation drive component 5, when the material cylinder 3 is below the main feed port 11 or outside the guide pipe 21, the linkage sleeve 4 can be driven to slide axially on the outside of the material cylinder 3. This allows the baffle 32 on the outside of the material cylinder 3 to be in the open and closed states when it is below the main feed port 11 and outside the guide pipe 21, respectively, to ensure the smooth operation of loading, unloading, and plasma roughing. During the loading and unloading process (i.e., when the material port 31 is in the open state), the material port 31 can be adjusted to be at the top or bottom by driving the material cylinder 3 to automatically adjust the opening upward after the material cylinder 3 is unloaded below the main feed port 11, making it easier to add the regulator to be processed into the material cylinder 3.

[0057] When installing and removing the material cylinder 3 in the plasma roughening treatment equipment for the surface of the regulator in this application, the notch of the drive disc 61 is positioned so that the notch at the top of the drive disc 61 is vertically aligned with the mounting opening 514 at the top of the fixing plate 511. This facilitates placing the trapezoidal column 34 of the material cylinder 3 from top to bottom inside the mounting groove 62 or removing it in the opposite direction. At this time, the narrow face of the trapezoidal column 34 is located at the bottom, and the material cylinder 3 can be axially positioned by the inclined surface of the outer side of the trapezoidal column 34. At the same time, the connecting ring 43 on the outer side of the linkage sleeve 4 is fitted with the support wheel 57 for installation. During installation, the support wheel 57 is positioned by its circumference. The isosceles trapezoidal shape facilitates the fit with the groove 44, and the two sides of the support wheel 57 fit snugly against the inner side of the groove 44 after fitting, preventing axial displacement between the groove 44 and the support wheel 57. Furthermore, when the material cylinder 3 drives the linkage sleeve 4 to rotate, it rotates within the inner ring of the connecting ring 43, thus preventing the groove 44 from rotating and causing wear on the support wheel 57. Moreover, under the cooperation of the support wheel 57 and the groove 44, when the vertical plate 55 moves horizontally, it can drive the connecting ring 43, the linkage sleeve 4, and the material cylinder 3 to move synchronously, achieving translational movement of the material cylinder 3 between the main feed inlet 11 and the guide pipe 21. It is worth noting that the above disassembly and assembly methods have the following advantages: Firstly, by setting the drive disc 61 to be detachably connected to the trapezoidal column 34 at one end of the material cylinder 3, the material cylinder 3 can be easily disassembled, and the trapezoidal column 34 and the drive disc 61 can be linked with the power source after installation, so that the material cylinder 3 can rotate continuously during the regulator's processing.

[0058] Secondly, by setting the support wheel 57 to cooperate with the groove 44, the support wheel 57 has a supporting function during the rotation of the material cylinder 3, so as to ensure the stability of the rotation of the material cylinder 3. During disassembly and assembly, the cooperation between the groove 44 and the support wheel 57 makes it easy to install and disassemble the linkage sleeve 4 on the outside of the material cylinder 3.

[0059] Thirdly, the isosceles trapezoidal structure around the support wheel 57 facilitates its engagement with the groove 44. After engagement, the two sides of the support wheel 57 fit snugly against the inner side of the groove 44, preventing axial displacement between the groove 44 and the support wheel 57. During translation, the support wheel 57 can drive the connecting ring 43 to move, which in turn drives the linkage sleeve 4 and the material cylinder 3 to translate, thus serving as the driving structure for translation.
