Description

Technical Field

[0001] The present invention relates to the technical field of transmission of shaft hinge parts, and more specifically, it relates to a heat treatment shaft hinge part transmission device. Background Art

[0002] A shaft hinge is a mechanical device used to connect two objects and allow them to rotate relative to each other within a certain angle range. It usually consists of a hinge head, a body, and a base. Shaft hinges are widely used in electronic products such as laptop computers and folding screen mobile phones to achieve the flipping of the screen or the lid.

[0003] In order to obtain a very high hardness on the surface of the shaft hinge and improve its wear resistance, the surface of the shaft hinge needs to be heat treated. The transmission device needs to transport the shaft hinge into the carburizing box to perform carburizing on the surface of the shaft hinge. When performing carburizing treatment, usually, the carburizing area of the carburizing box is located at the upper position inside it. This is because the temperature distribution and atmosphere conditions in the upper area are often more suitable for the infiltration and diffusion of carbon elements, so that the carburizing effect can be achieved more effectively. Therefore, after the shaft hinge is transported into the carburizing box, it is also necessary to further transport it upward to ensure that it can accurately reach the carburizing area of the carburizing box. In this way, the shaft hinge can receive carburizing treatment under suitable temperature and atmosphere conditions, so that carbon elements can uniformly infiltrate its surface to form the required carburized layer.

[0004] After the transmission device transports the shaft hinge upward, the carburizing box will start to carburize the shaft hinge. Since the lower area of the carburizing box is not sealed, the heat inside the carburizing box will be dissipated, resulting in a decrease in the heat inside the carburizing box, and then resulting in insufficient hardness on the surface of the parts, unable to meet the expected hardness requirements, thus affecting its wear resistance and fatigue resistance. Moreover, when the shaft hinge is being transported, the distance between the upper and lower shaft hinges cannot be adjusted, resulting in the distance between the upper and lower shaft hinges being too close. Being too close will hinder the full circulation of the atmosphere in the furnace, resulting in uneven carburized layers, with local carburizing deficiencies or over-carburizing phenomena occurring.

[0005] Therefore, it is necessary to design a heat treatment shaft hinge part transmission device that can automatically adjust the distance between parts and ensure uniform carburizing to improve the above-mentioned existing technical problems. Summary of the Invention

[0006] Aiming at the deficiencies of the existing technology, the purpose of the present invention is to provide a heat treatment shaft hinge part transmission device.

[0007] To achieve the above object, the present invention provides the following technical solutions: A heat treatment rotating shaft hinge part transmission device, including a slide rail, on the upper side of the slide rail is fixedly connected with a carburizing box, on one side of the carburizing box is provided a conveying mechanism for transporting the rotating shaft hinge, on the upper side of the conveying mechanism is provided an adjusting mechanism for adjusting the distance between the upper and lower two rotating shaft hinges and indirectly cleaning the accumulated carbon black, and inside the adjusting mechanism is provided a diversion mechanism for introducing heat to the center of the adjusting mechanism.

[0008] The present invention is further provided as follows: The conveying mechanism includes four electric rollers slidably connected inside the slide rail, on the upper side of the electric rollers is fixedly connected with a support frame, inside the support frame are uniformly fixedly connected with four electric push rods, the output ends of the four electric push rods all penetrate the support frame, inside the support frame is slidably connected with a fixing plate, on the lower inner wall of the fixing plate is fixedly connected with a cylinder, the output end of the cylinder is fixedly connected with a U-shaped plate, and inside the U-shaped plate is fixedly connected with a motor.

[0009] The present invention is further provided as follows: The adjusting mechanism includes a closing plate fixedly connected to the output ends of the four electric push rods, the closing plate is a manganese metal plate with poor thermal conductivity, the fixing plate is fixedly connected with the closing plate, on the upper side of the closing plate are successively provided a first support plate, a second support plate, a third support plate and a fourth support plate, on both sides of the first support plate are respectively hinged with two third connecting rods, the two third connecting rods are hinged to each other, the other ends of the two third connecting rods are respectively hinged with second connecting rods, the two second connecting rods are hinged to each other, and the other ends of the two second connecting rods are respectively hinged with first connecting rods, and the two first connecting rods are hinged to each other.

[0010] The present invention is further provided as follows: Both sides of the second support plate are hinged with the second connecting rod and the third connecting rod, both sides of the third support plate are hinged with the first connecting rod and the second connecting rod, and both sides of the fourth support plate are hinged with the first connecting rod.

[0011] The present invention is further provided as follows: The first support plate, the second support plate, the third support plate and the fourth support plate have the same structure, the fourth support plate is composed of two guide slides and a slide plate, the slide plate is slidably connected between the two guide slides, and the first support plate is fixedly connected with the closing plate.

[0012] By precisely controlling the extension of the output end of the electric push rod, the four walls of the sealing plate are closely attached to the inner wall of the carburizing box. This design effectively prevents most of the heat loss inside the carburizing box, ensures the stability of the temperature inside the box, and thus provides a good thermal environment for the carburizing process. At the same time, the output end of the cylinder extends, driving the first connecting rod, the second connecting rod, and the third connecting rod to unfold. This action increases the distance between the upper and lower rotating shaft hinges. As the distance between the rotating shaft hinges increases, the atmosphere inside the carburizing box can circulate and distribute more fully, enabling carbon particles to contact all parts of the part more evenly, thereby significantly improving the uniformity of the carburized layer. This optimized mechanical structure and control method not only improve the carburizing efficiency but also ensure the quality and performance of the carburized layer on the part surface, laying a solid foundation for the subsequent heat treatment process.

[0013] The present invention is further configured such that: second avoidance grooves are provided inside the first connecting rod, the second connecting rod, and the third connecting rod. Inside the first connecting rod, a first scraping plate, a second scraping plate, and a third scraping plate are respectively hinged. A first avoidance groove is provided inside the second scraping plate.

[0014] The present invention is further configured such that: a fourth scraping plate, a fifth scraping plate, and a sixth scraping plate are respectively hinged inside the second connecting rod. A third avoidance groove is provided inside the fifth scraping plate. Three first collection boxes are uniformly fixedly connected inside the second avoidance groove of the second connecting rod. Three second collection boxes are uniformly fixedly connected inside the second avoidance groove of the third connecting rod.

[0015] By controlling the retraction of the output end of the cylinder, the first connecting rod, the second connecting rod, and the third connecting rod can be driven to perform a contraction action. This process not only reduces the height of the uppermost rotating shaft hinge, thus effectively preventing the uppermost rotating shaft hinge from hitting the carburizing box when moving outside the carburizing box subsequently, ensuring the safe and smooth operation of the equipment. At the same time, the contraction action of the cylinder also indirectly controls the rotation of the first scraping plate, the second scraping plate, the third scraping plate, the fourth scraping plate, the fifth scraping plate, and the sixth scraping plate. During the rotation of these scraping plates, most of the carbon black above the second connecting rod and the third connecting rod can be cleaned, avoiding the problem that the connecting rod cannot be fully contracted due to carbon black accumulation. In this way, the phenomenon that the rotating shaft hinge is stuck inside the carburizing box is effectively prevented, thereby improving the efficiency and reliability of the entire conveying system and ensuring the continuity and stability of the production process.

[0016] The present invention is further configured such that: the air guiding mechanism includes a wind guiding cylinder fixedly connected to the output end of the motor. A plurality of air outlet holes are uniformly provided on the inner wall of the wind guiding cylinder. A heat conducting fan is fixedly connected above the inside of the wind guiding cylinder. Three material supporting trays are uniformly connected to the outer wall of the wind guiding cylinder. A supporting ring is also fixedly connected to the outer wall of the wind guiding cylinder.

[0017] The present invention is further configured such that: a plurality of positioning grooves are uniformly and fixedly connected above the inner wall of the material supporting tray, a plurality of second ventilation holes are uniformly arranged inside the material supporting tray, a plurality of first ventilation holes communicate with the upper side of each of the second ventilation holes, and a positioning rod is arranged above each of the positioning grooves and the positioning rod is hinged to the material supporting tray.

[0018] By controlling the rotation of the rotating shaft hinge and the heat-conducting fan by the motor, a large number of carbon particles in other areas can be effectively sucked into the inside of the air guide cylinder, that is, the middle area of the material supporting tray. These carbon particles are then discharged through the internal channels of the air outlet hole, the second ventilation hole, and the first ventilation hole. The discharged carbon particles are evenly distributed on the material supporting tray to perform uniform carburizing treatment on the surface of the rotating shaft hinge. This process not only ensures the uniformity of the carburized layer but also effectively prevents the phenomenon of insufficient or excessive carburizing of the rotating shaft hinge in the middle of the material supporting tray.

[0019] In summary, the present application includes at least one of the following beneficial technical effects:

[0020] 1. By controlling the extension of the output end of the electric push rod, the four walls of the closing plate are attached to the inner wall of the carburizing box, effectively preventing most of the heat loss inside the carburizing box. And when the output end of the cylinder extends, it drives the first connecting rod, the second connecting rod, and the third connecting rod to unfold, so that the distance between the upper and lower rotating shaft hinges increases, and the atmosphere inside the carburizing box circulates fully, improving the uniformity of the carburized layer.

[0021] 2. By retracting the output end of the cylinder, it drives the first connecting rod, the second connecting rod, and the third connecting rod to contract. This not only reduces the height of the uppermost rotating shaft hinge to prevent the uppermost rotating shaft hinge from hitting the carburizing box when moving outside the carburizing box subsequently, but also indirectly controls the rotation of the first scraper, the second scraper, the third scraper, the fourth scraper, the fifth scraper, and the sixth scraper, and most of the carbon black above the second connecting rod and the third connecting rod is cleaned up, effectively preventing the phenomenon that the second connecting rod and the third connecting rod cannot be fully retracted and the rotating shaft hinge is stuck inside the carburizing box, achieving the effect of high conveying efficiency.

[0022] 3. By controlling the rotation of the rotating shaft hinge and the heat-conducting fan by the motor, a large number of carbon particles in other areas are sucked into the inside of the air guide cylinder, that is, the middle area of the material supporting tray, and then discharged in sequence through the air outlet hole, the second ventilation hole, and the first ventilation hole. The discharged carbon particles perform uniform carburizing on the surface of the rotating shaft hinge on the material supporting tray, achieving the effect of uniform carburizing, and effectively preventing the phenomenon of uneven carburized layer of the rotating shaft hinge in the middle of the material supporting tray, such as insufficient or excessive carburizing in local areas.

[0037] It should be noted that, without conflict, the embodiments in the present application and the features in the embodiments can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0038] It should be pointed out that unless otherwise specified, all technical and scientific terms used in the present application have the same meaning as commonly understood by those of ordinary skill in the technical field to which the present application belongs.

[0039] Embodiment 1, please refer to Figures 1 - 10 , the present invention provides the following technical solution: A heat treatment rotating shaft hinge part transmission device, including a slide rail 1, a carburizing box 2 is fixedly connected to the upper side of the slide rail 1, a conveying mechanism 3 for transporting the rotating shaft hinge is provided on one side of the carburizing box 2, an adjusting mechanism 4 for adjusting the distance between the upper and lower rotating shaft hinges and indirectly cleaning the accumulated carbon black is provided on the upper side of the conveying mechanism 3, and a diversion mechanism 5 for introducing heat into the center of the adjusting mechanism 4 is provided inside the adjusting mechanism 4.

[0040] Specifically, the inside of the carburizing box 2 is used for carburizing the rotating shaft hinge, and the slide rail 1 is used for guiding the conveying mechanism 3.

[0041] Please refer to Figure 2 , the conveying mechanism 3 includes four electric rollers 31 slidably connected inside the slide rail 1, a support frame 32 is fixedly connected to the upper side of the electric rollers 31, four electric push rods 33 are uniformly fixedly connected inside the support frame 32, the output ends of the four electric push rods 33 all penetrate the support frame 32, a fixing plate 37 is slidably connected inside the support frame 32, a cylinder 36 is fixedly connected to the lower inner wall of the fixing plate 37, the output end of the cylinder 36 is fixedly connected to a U-shaped plate 35, and a motor 34 is fixedly connected inside the U-shaped plate 35.

[0042] Specifically, the electric roller 31 is controlled by an internal drive motor to rotate, thereby driving the adjusting mechanism 4 and the diversion mechanism 5 to move, and further driving the rotating shaft hinge to move into the carburizing box 2. The extension of the output end of the electric push rod 33 is used to control the adjusting mechanism 4 and the diversion mechanism 5 to move upward, so that the rotating shaft hinge moves to the carburizing area of the carburizing box 2. When the electric push rod 33 is fully extended, the four walls of the closing plate 41 are in contact with the inner wall of the carburizing box 2 to form a closed box to prevent most of the heat from escaping. The rotation of the output end of the motor 34 is used to control the rotation of the diversion mechanism 5, and the extension of the output end of the cylinder 36 is used to control the unfolding of the adjusting mechanism 4, thereby increasing the distance between the two rotating shaft hinges.

[0043] Please refer to Figure 3, the adjusting mechanism 4 includes a closing plate 41 fixedly connected to the output ends of four electric push rods 33. The closing plate 41 is a manganese metal plate with poor thermal conductivity. The fixing plate 37 is fixedly connected to the closing plate 41. On the upper side of the closing plate 41, a first support plate 42, a second support plate 43, a third support plate 44, and a fourth support plate 45 are sequentially arranged. Two third connecting rods 48 are respectively hinged on both sides of the first support plate 42. The two third connecting rods 48 are hinged to each other. The other ends of the two third connecting rods 48 are respectively hinged to second connecting rods 47. The two second connecting rods 47 are hinged to each other. The other ends of the two second connecting rods 47 are respectively hinged to first connecting rods 46. The two first connecting rods 46 are hinged to each other.

[0044] Specifically, when the shaft hinge needs to be carburized, the electric roller 31 drives the shaft hinge to move into the carburizing box 2. At this time, the output end of the electric push rod 33 extends, controlling the shaft hinge to move upward, so that the shaft hinge moves to the carburizing area of the carburizing box 2. When the electric push rod 33 is fully extended, the four walls of the closing plate 41 are attached to the inner wall of the carburizing box 2 to prevent heat loss in the carburizing area. The output end of the cylinder 36 extends, driving the motor 34 to move upward, thereby driving the drainage mechanism 5 to move upward, and further driving the fourth support plate 45 to move upward by the drainage mechanism 5. While the fourth support plate 45 moves, the first support plate 42 and the second support plate 43 move simultaneously, thereby driving the first connecting rod 46, the second connecting rod 47, and the third connecting rod 48 to unfold. At this time, the distance between the upper and lower shaft hinges increases, enabling the atmosphere inside the carburizing box 2 to circulate fully and improving the uniformity of the carburized layer.

[0045] After the carburizing of the shaft hinge is completed, the output end of the cylinder 36 retracts, and the fourth support plate 45 is driven by the drainage mechanism 5 to move downward. While the fourth support plate 45 moves, the first support plate 42 and the second support plate 43 move simultaneously, thereby driving the first connecting rod 46, the second connecting rod 47, and the third connecting rod 48 to contract. At this time, the distance between the upper and lower shaft hinges shortens, and the height of the uppermost shaft hinge decreases, effectively preventing the uppermost shaft hinge from hitting the carburizing box 2 when moving out of the carburizing box 2 subsequently. The output end of the electric push rod 33 retracts, controlling the shaft hinge to move up and down, so that the shaft hinge leaves the carburizing area of the carburizing box 2. Finally, the electric roller 31 drives the shaft hinge to move out of the carburizing box 2.

[0046] Both sides of the second support plate 43 are hinged to the second connecting rod 47 and the third connecting rod 48. Both sides of the third support plate 44 are hinged to the first connecting rod 46 and the second connecting rod 47. Both sides of the fourth support plate 45 are hinged to the first connecting rod 46.

[0047] Please refer to Figure 4, the first support plate 42, the second support plate 43, the third support plate 44 and the fourth support plate 45 have the same structure. The fourth support plate 45 is composed of two guide slides 452 and a slide plate 451. The slide plate 451 is slidably connected between the two guide slides 452. The first support plate 42 is fixedly connected to the closing plate 41.

[0048] Specifically, when the first link 46, the second link 47 and the third link 48 are extended, the two guide slides 452 slide towards the slide plate 451. On the contrary, when the first link 46, the second link 47 and the third link 48 contract, the two guide slides 452 slide in the opposite direction.

[0049] By controlling the output end of the electric push rod 33 to extend, the four walls of the closing plate 41 are attached to the inner wall of the carburizing box 2, effectively preventing most of the heat loss inside the carburizing box 2. And when the output end of the air cylinder 36 extends, it drives the first link 46, the second link 47 and the third link 48 to extend, thereby increasing the distance between the upper and lower shaft hinges, enabling the atmosphere inside the carburizing box 2 to circulate fully, and improving the uniformity of the carburized layer.

[0050] In the second embodiment, after the shaft hinge carburizing is completed, carbon black will accumulate above the three links. The accumulation of carbon black will prevent the two links from fully contracting, so that when the two links contract, they will get stuck, and then the height of the uppermost shaft hinge cannot drop to the safe area. When moving out of the inside of the carburizing box 2, it will collide with the carburizing box 2, causing the shaft hinge to get stuck inside the carburizing box 2, resulting in the inability to carry out the subsequent transportation of the shaft hinge and reducing the conveying efficiency of the shaft hinge.

[0051] Please refer to Figures 5 - 7 , second avoidance grooves 465 are provided inside the first link 46, the second link 47 and the third link 48. The first link 46 is internally hinged with a first scraping plate 461, a second scraping plate 462 and a third scraping plate 464 respectively. A first avoidance groove 463 is provided inside the second scraping plate 462.

[0052] Specifically, when the first link 46, the second link 47 and the third link 48 are fully extended to their maximum positions, due to gravity, the first scraping plate 461, the second scraping plate 462 and the third scraping plate 464 will rotate from the second avoidance groove 465 on the first link 46, and thus hang down naturally, forming a vertically downward state. Similarly, the fourth scraping plate 472, the fifth scraping plate 473 and the sixth scraping plate 475 will also rotate from the second avoidance groove 465 on the second link 47, presenting a vertically downward state. Since the scraping plates are in a vertically downward position, this helps to prevent carbon black from accumulating on the scraping plates, because the gravity will make the carbon black slide off more easily, thus keeping the scraping plates clean and operating effectively.

[0053] The inner parts of the second connecting rod 47 are respectively hinged with a fourth scraper 472, a fifth scraper 473 and a sixth scraper 475. A third avoidance groove 474 is arranged inside the fifth scraper 473. Three first collection boxes 471 are uniformly and fixedly connected inside the second avoidance groove 465 of the second connecting rod 47. Three second collection boxes 481 are uniformly and fixedly connected inside the second avoidance groove 465 of the third connecting rod 48.

[0054] Specifically, the first collection box 471 and the second collection box 481 are used to respectively collect the carbon black generated above the second connecting rod 47 and the third connecting rod 48. When the first connecting rod 46, the second connecting rod 47 and the third connecting rod 48 start to change from the fully extended state to the contracted state, the first scraper 461, the second scraper 462 and the third scraper 464 will move downward as the connecting rods contract until they abut against the upper surface of the second connecting rod 47. Please refer to Figure 8 , subsequently, the first scraper 461, the second scraper 462 and the third scraper 464 will move along the length direction of the second connecting rod 47. Through the movement of the scrapers, the carbon black attached above the second connecting rod 47 is effectively scraped off. As the scrapers advance, the scraped carbon black will be sequentially guided and pushed into the interior of each first collection box 471, thereby realizing the orderly collection and treatment of the carbon black above the second connecting rod 47.

[0055] As the first connecting rod 46, the second connecting rod 47 and the third connecting rod 48 contract, the fourth scraper 472, the fifth scraper 473 and the sixth scraper 475 will move downward until they contact the upper surface of the third connecting rod 48. Then, the fourth scraper 472, the fifth scraper 473 and the sixth scraper 475 will move along the length direction of the third connecting rod 48, effectively scraping off the carbon black attached above the third connecting rod 48. As the scrapers advance, the scraped carbon black will be sequentially guided and pushed into the interior of each second collection box 481, thereby realizing the orderly collection and treatment of the carbon black above the third connecting rod 48. When the first connecting rod 46, the second connecting rod 47 and the third connecting rod 48 are completely contracted to the initial position, most of the carbon black above the second connecting rod 47 and the third connecting rod 48 has been cleaned. At this time, the first scraper 461, the second scraper 462 and the third scraper 464 will return to the second avoidance groove 465 inside the first connecting rod 46, while the fourth scraper 472, the fifth scraper 473 and the sixth scraper 475 will return to the second avoidance groove 465 inside the second connecting rod 47, preparing for the next scraping action.

[0056] When the output end of the air cylinder 36 retracts, it drives the first connecting rod 46, the second connecting rod 47 and the third connecting rod 48 to contract, which not only reduces the height of the topmost rotating shaft hinge, preventing the topmost rotating shaft hinge from hitting the carburizing box 2 when moving outside the carburizing box 2 subsequently, but also indirectly controls the rotation of the first scraper 461, the second scraper 462, the third scraper 464, the fourth scraper 472, the fifth scraper 473 and the sixth scraper 475, cleaning most of the carbon black above the second connecting rod 47 and the third connecting rod 48, effectively preventing the phenomenon that the second connecting rod 47 and the third connecting rod 48 cannot fully contract and the rotating shaft hinge is stuck inside the carburizing box 2, achieving the effect of high conveying efficiency.

[0057] Embodiment 3. In the carburizing box 2, since the carburizing mechanism inside it is mainly distributed on the four inner walls, this causes carbon particles to be difficult to reach the middle area of the material supporting tray 55 evenly. On the contrary, a large amount of carbon particles will be sprayed on the outer side of the material supporting tray 55. Due to this uneven distribution, the rotating shaft hinges in the middle and on the outer side of the material supporting tray 55 cannot effectively obtain a uniform carburizing effect. As a result, the phenomenon of uneven carburized layer appears on the rotating shaft hinge in the middle of the material supporting tray 55, which may lead to insufficient carburizing in some local areas, while over-carburizing may occur in other areas.

[0058] Please refer to Figure 9 and Figure 10 , the drainage mechanism 5 includes a wind guide cylinder 52 fixedly connected to the output end of the motor 34. The wind guide cylinder (52) is arranged in the vertically aligned central openings of the first support plate (42), the second support plate (43), the third support plate (44) and the fourth support plate (45). A plurality of air outlet holes 51 are evenly arranged on the inner wall of the wind guide cylinder 52. A heat-conducting fan 53 is fixedly connected above the inside of the wind guide cylinder 52. Three material supporting trays 55 are evenly connected to the outer wall of the wind guide cylinder 52. A support ring 54 is also fixedly connected to the outer wall of the wind guide cylinder 52.

[0059] Specifically, the supporting ring 54 is used to support and move the fourth support plate 45 upward. A large number of hinge shafts to be carburized can be placed inside the material supporting tray 55. The rotation of the output end of the motor 34 is used to control the rapid rotation of the three material supporting trays 55 and the air guide cylinder 52, thereby controlling the rapid rotation of the hinge shafts and the heat conduction fans 53. When the hinge shafts rotate, it can accelerate the diffusion of carbon atoms to the surface of the hinge shafts, making the carbon element penetrate more evenly into the surface of the hinge shafts, thereby improving the carburizing efficiency. During the rotation process, the contact between the surface of the hinge shafts and the carburizing medium is more sufficient, which helps to form a uniform and dense carburized layer, improving the hardness and wear resistance of the carburized layer. The rapid rotation can also prevent the hinges from staying at a certain position for a long time, reducing the occurrence of local over-carburization phenomenon and ensuring the uniformity of the carburized layer. When the heat conduction fan 53 rotates, suction can be generated above the air guide cylinder 52, sucking a large number of carbon particles above the air guide cylinder 52 into the air guide cylinder 52. A large number of particles inside the air guide cylinder 52 are then discharged from each air outlet hole 51 inside the air guide cylinder 52, thereby transferring a large number of carbon particles in other areas to the middle area of the material supporting tray 55.

[0060] A number of positioning grooves 553 are uniformly and fixedly connected to the upper part of the inner wall of the material supporting tray 55. A number of second ventilation holes 552 are uniformly arranged inside the material supporting tray 55. The upper side of each second ventilation hole 552 communicates with a number of first ventilation holes 551. A positioning rod 554 is arranged above each positioning groove 553 and the positioning rod 554 is hinged to the material supporting tray 55.

[0061] Specifically, the positioning grooves 553 are used to place the hinge shafts inside. The positioning rods 554 are used to fix each hinge shaft to prevent the hinge shafts from being thrown off during rapid rotation. When a large number of carbon particles are discharged from each air outlet hole 51 inside the air guide cylinder 52, some carbon particles will directly be discharged above the area of each hinge shaft. Another part of the carbon particles will enter the inside of the second ventilation holes 552 again. The second ventilation holes 552 are located below or on the left and right sides of each hinge shaft, and then are transmitted from the inside of the second ventilation holes 552 to the inside of each first ventilation hole 551. The first ventilation holes 551 then transmit some carbon particles to the periphery of each hinge shaft, that is, below, to the left and to the right of each hinge shaft, so as to uniformly carburize each hinge shaft.

[0062] By controlling the rotation of the hinge shafts and the heat conduction fans 53 through the motor 34, a large number of carbon particles in other areas are sucked into the air guide cylinder 52, that is, the middle area of the material supporting tray 55, and then are discharged in turn through the air outlet holes 51, the second ventilation holes 552 and the first ventilation holes 551. The discharged carbon particles uniformly carburize the surface of the hinge shafts on the material supporting tray 55, achieving the effect of uniform carburization, effectively preventing the uneven carburized layer of the hinge shafts in the middle of the material supporting tray 55, and avoiding the phenomenon of local carburization deficiency or over-carburization.

[0063] Inspired by the above-described ideal embodiments of the present invention, through the above description, relevant staff can completely make various changes and modifications without departing from the technical idea of this invention. The technical scope of this invention is not limited to the content in the specification, and its technical scope must be determined according to the scope of the claims.
