[0005] In the prior art, there are still the following deficiencies in the process of placing the crochet hooks in the magnetron sputtering coating equipment for coating: 1. When coating the crochet hooks, multiple crochet hooks need to be placed on a placement rack, and the placement rack is placed in the magnetron sputtering coating equipment for coating. To ensure the coating efficiency, generally, a large number of crochet hooks are placed on the placement rack, so the total weight of the placement rack and the crochet hooks is extremely large. When putting the placement rack in and taking it out, most of the time, manual intervention or handling is required, and thus it is extremely inconvenient to put the placement rack in and take it out. 2. During the coating process, the crochet hooks are placed on the placement rack, and the contact surface between the crochet hooks and the placement rack is blocked. Therefore, during coating, the contact surface between the two cannot be evenly coated, affecting the appearance and use effect of the crochet hooks. Summary of the Invention

[0012] In a possible design, the jolting structure includes a plurality of second gears rotatably disposed on the top of the fixed disk. The plurality of second gears are respectively fixedly connected to the top end of the rotating cylinder. A rotating column rotatably penetrates through the fixed column, and the top end of the rotating column rotatably penetrates the fixed disk. A third gear is fixedly attached to the outer wall of the rotating column above the fixed disk by bolts. The second gear meshes with the third gear. When the fixed column drives the fixed disk and the rotating cylinder to rotate, the meshing between the second gear and the third gear can drive the second gear to rotate on its own axis. A plurality of chute groups are provided inside the rotating cylinder. Each chute group is composed of a plurality of through grooves. A drag plate is slidably connected to the outer wall of the rotating cylinder through the chute group. The drag plate is located below the adjacent second limiting rods and is used to push the hook needle body up and down later.

When the rotating cylinder drives the transmission rod to rotate on its own axis, the transmission rod drives the transmission rod to move up and down reciprocally under the action of the top disk, so that the drag plate can drive the hook needle body to move up and down, completing a full-range coating operation; the rotating disk drives the chassis and the fixed column thereon to rotate. The rotating column remains stationary under the extrusion of the positioning column. The third gear fixed to the outer wall of the rotating column meshes with the second gear. When the fixed column drives the fixed disk to rotate, the second gear drives the rotating cylinder to rotate on its own axis under the action of the third gear, driving a plurality of hook needle bodies placed in the second limiting rods to revolve around the rotating cylinder as the center for coating operations. In addition, the transmission rod is slidably matched with the rotating cylinder. The rotating cylinder synchronously drives the transmission rod to rotate. The transmission rod is threadedly connected to the top disk through the reciprocating thread section. Therefore, when the transmission rod rotates, it can move up and down reciprocally. When the reciprocating thread section drives the drag plate to move upward, it can lift the hook needle body up a certain distance, exposing the part of the hook needle body blocked by the second limiting rod for coating. Therefore, the hook needle body can be evenly coated in all directions, ensuring the uniformity of the coating.

A positioning column slidably penetrates through the fixed cylinder, and the bottom end of the positioning column extends below the fixed cylinder. A positioning spring is fixed between the top end of the positioning column and the inner wall of the top of the fixed cylinder. The positioning spring cooperates with the top end of the rotating column. The positioning column applies pressure to the rotating column under the action of the second spring, enabling the rotating column to remain stationary when the chassis and the fixed column rotate, facilitating the later full-range and uniform coating of a plurality of hook needle bodies.

[0014] In a possible design, the outer walls of a plurality of the rotating cylinders are all rotatably sleeved with first limiting rods through rotating bearings. One ends of the plurality of first limiting rods are all fixedly connected to the fixed column, which is used to ensure the stability of the rotating cylinder when it rotates on its own axis.

[0015] In a possible design, the bottom inner wall of the equipment body is rotatably connected to a first gear, and the outer wall fixed sleeve of the rotating disk is provided with a gear ring meshing with the first gear, which is used to drive the rotating disk to rotate. Two second support plates are fixed to the side of the equipment body close to the warehouse door. The second support plates are consistent in height with the first support plates and are used to support the padding plate when it is placed horizontally. When the padding plate is placed horizontally, its top is flush with the top of the rotating disk.

[0016] In a possible design, there are multiple rotating tables running through the inside of the drag plate, and the rotating tables are located below the hook body and are used to push the hook body up and down. A fixed shaft is fixed to the bottom of the rotating table, and fan blades are fixed to the outer wall of the fixed shaft by screws. The fan blades cooperate with the gas in the device body and are used to make the fixed shaft rotate when the drag plate moves up and down; when the transmission rod drives the drag plate to move back and forth up and down, the fan blades contact the gas inside the device body, and the gas can generate a driving force for the fan blades when flowing on the surface of the fan blades, so that the fan blades and the rotating table rotate, and when the drag plate moves up and down and the rotating table contacts the bottom end of the hook body, due to the light weight of the hook body, the rotating table can drive the hook body to rotate, and adjust the direction of the hook body to ensure the uniformity of the coating.

[0017] Beneficial effect: In the present invention, two locating pins are slidably penetrated in the movable seat, and the tops of the two locating pins are fixed with the same T-plate, and the side of the locating pin close to the door of the equipment body is provided with an inclined surface, and a top rod fixedly connected to the bottom end of the T-plate is sealed and slidably connected in the circular groove, and a piston plate is sealed and slidably connected in the rectangular groove, and a push rod is fixed on the side of the piston plate away from the first spring; the locating pin can be stuck in the locating groove under the action of the tension spring and the inclined surface, so as to complete the fixation of the chassis and the movable seat, and facilitate the automatic placement and removal of the movable seat, and the push rod can contact with the inner wall of the movable groove to inject the air in the rectangular groove into the circular groove and push the locating pin to disengage from the locating groove, so as to automatically complete the disengagement between the movable seat and the chassis, and facilitate the staff to take out the placement rack; In the present invention, a worm wheel is fixed to the outer wall of the rotating shaft, a worm is rotatably connected in the bracket, a second disc is fixed to one end of the worm, a plurality of second magnets are fixed to the side of the second disc close to the rotating disc, one end of the lead screw is meshed with the circular shaft through a gear, one end of the circular shaft is rotatably extended into the give way groove and a first disc is fixed, a plurality of first magnets are fixed to one side of the first disc; when the lead screw rotates, the first disc is driven to rotate through the meshing between the gears, and the first disc and the second disc can be transmitted through the magnetic attraction between the first magnet and the second magnet, so that the padding plate can be driven to rotate through the worm, which is convenient for placing it on the padding plate and removing it later; In the present invention, a plurality of sliding plates are slidably connected inside the rotating cylinder. A transmission rod is slidable inside the rotating cylinder. The sliding plates are fixed to the outer wall of the transmission rod. A reciprocating thread section is provided on the outer wall of the transmission rod. The transmission rod is threadedly connected to the top plate through the reciprocating thread section. The rotating disk drives the chassis and the fixed column thereon to rotate. The rotating column remains stationary under the extrusion of the positioning column. The rotating cylinder rotates self-driven under the cooperation of the second gear and the third gear. The rotating cylinder synchronously drives the transmission rod to rotate. The transmission rod is threadedly connected to the top plate through the reciprocating thread section. Therefore, when the transmission rod rotates, it drives the sliding plates to move up and down reciprocally, exposing the part of the hook needle body blocked by the second limiting rod for coating. Thus, the hook needle body can be coated evenly in all directions, ensuring the uniformity of the coating. In the present invention, a plurality of rotating platforms rotatably penetrate through the sliding plates. A fixed shaft is fixed to the bottom of the rotating platform. A fan blade is fixed to the outer wall of the fixed shaft. When the transmission rod drives the sliding plates to move up and down reciprocally, the fan blade contacts the gas inside the equipment main body, and when the gas flows on the surface of the fan blade, it can generate a driving force on the fan blade, causing the fan blade and the rotating platform to rotate. When the sliding plate moves upward and the rotating platform contacts the bottom end of the hook needle body, since the mass of the hook needle body is relatively light, the rotating platform can drive the hook needle body to rotate, reversing the orientation direction of the hook needle body, ensuring the uniformity of the coating.

[0018] In the present invention, the placement rack can be automatically put in and taken out, greatly saving manpower. And during the coating process, the hook needle body can be driven to move up and down while revolving, and when moving up and down, the rotating platform drives the hook needle body to rotate self-driven, enabling the hook needle body to be evenly coated in all directions and without dead angles, avoiding the position of the hook needle body blocked by the second limiting rod from being unevenly coated.

Detailed implementation manners

[0021] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0022] Embodiment 1: Refer to Figures 1 - 3 , a coating preparation device, which relates to the technical field of coating, and is used for uniformly coating a textile hook needle and automatically loading and unloading. The whole device includes an equipment main body 1, and the bottom inner wall of the equipment main body 1 is rotatably connected to a rotating disk 2 through a bearing. The rotating disk 2 can rotate smoothly in the equipment main body 1 to cooperate with subsequent coating processes and loading and unloading operations.

[0023] Refer toFigure 2 , Figure 9 and Figure 12 , a placement rack is placed on the top of the rotating disk 2, and the placement rack is used to place a plurality of crochet hook bodies 42. The specific structure of the placement rack includes a chassis 29 and fixing columns 31 fixedly welded to the chassis 29. A fixing disk 36 is fixedly welded to the top of the fixing columns 31, and a plurality of crochet hook bodies 42 are placed in the space surrounded by the fixing disk 36 and the fixing columns 31.

[0024] Refer to Figures 4 - 7 and Figure 12 , in order to automatically complete the placing and taking out of the placement rack, a feeding structure is arranged in the rotating disk 2. A moving seat 18 in the feeding structure is slidably arranged in a moving groove 5 in the rotating disk 2. The moving groove 5 is opened at the top of the rotating disk 2. A lead screw 6 is rotatably connected in the moving groove 5. One end of the lead screw 6 is connected to the output shaft of a motor arranged outside the rotating disk 2 through a coupling, and the motor drives the lead screw 6 to rotate. The moving seat 18 is threadedly connected to the lead screw 6. When the lead screw 6 rotates, it can drive the moving seat 18 to move in the moving groove 5. A plurality of groups of positioning hole groups are arranged on the top of the chassis 29, and each group of positioning hole groups is composed of two positioning grooves 30. Two positioning pins 19 penetrate through the moving seat 18 in a sliding manner, and the two positioning pins 19 are inserted and matched with the corresponding positioning grooves 30. When the positioning pins 19 are inserted into the positioning grooves 30, the moving seat 18 can be fixed to the chassis 29, which is convenient for the moving seat 18 to drive the chassis 29 to move later to complete the placing and taking out operations of the placement rack. The tops of the two positioning pins 19 are fixed with the same T-shaped plate 21, and two tension springs 20 are fixed between the bottom of the T-shaped plate 21 and the top of the moving seat 18. The two tension springs 20 are respectively sleeved on the outer walls of the positioning pins 19. One side of the positioning pin 19 close to the door of the equipment main body 1 is provided with an inclined surface. When the chassis 29 is pushed towards the moving seat 18, the inclined surface of the positioning pin 19 cooperates with the chassis 29 to enable the positioning pin 19 to move upward until the positioning pin 19 is inserted into the positioning groove 30 under the action of the tension spring 20.

[0025] During specific operation, the placement rack is pushed inward on the cushion plate 16. The chassis 29 can drive the positioning pin 19 to move upward under the action of the inclined surface of the positioning pin 19 until the bottom end of the positioning pin 19 moves to the top of the chassis 29. At this time, the two positioning pins 19 are inserted into the corresponding positioning grooves 30 under the action of the tension springs 20 to fix the chassis 29 to the moving seat 18. Then the motor is started, and the lead screw 6 rotates to move the chassis 29 inward until it moves to the center position of the rotating disk 2 to complete the placing operation of the placement rack.

[0026] Refer to Figure 4 and Figure 7, the feeding structure further includes a circular groove 22 provided at the top of the moving seat 18. A top rod 23, which is fixedly connected to the bottom end of the T-shaped plate 21 by bolts, is hermetically and slidably connected in the circular groove 22. A rectangular groove 24 is provided in the moving seat 18 and is located below the lead screw 6. The rectangular groove 24 communicates with the circular groove 22 through a liquid guide pipe 25. A piston plate 26 is hermetically and slidably connected in the rectangular groove 24. A plurality of first springs 28 are fixed to one side of the piston plate 26, and the first springs 28 are fixed in the rectangular groove 24. A push rod 27 is fixed to the side of the piston plate 26 away from the first springs 28. One end of the push rod 27 extends to one side of the moving seat 18 and abuts against the inner wall of one side of the moving groove 5.

[0027] Specifically, when the moving seat 18 moves to one end of the moving groove 5, the push rod 27 is squeezed to push the piston plate 26 to move, inject the gas in the rectangular groove 24 into the circular groove 22 through the liquid guide pipe 25, and push the T-shaped plate 21 to move upward, so that the positioning pin 19 disengages from the positioning groove 30. At this time, the placement rack can be conveniently removed from the moving seat 18, and the removal operation of the placement rack is completed.

[0028] The feeding structure further includes a receiving structure for enabling the placement rack to move smoothly in the equipment main body 1 during the process of putting the placement rack in and taking it out.

[0029] Refer to Figure 4 、 Figure 5 、 Figure 6 and Figure 8, its receiving structure includes a rotating shaft 15 rotatably mounted in the device body 1 through a base. A padding plate 16 is fixedly sleeved on the outer wall of the rotating shaft 15, and the padding plate 16 is used to provide stable moving support during the process of placing the rack into and taking out the device body 1. A worm gear 17 is fixed to the outer wall of the rotating shaft 15 by screws, and a first support plate 11 is fixed to the bottom inner wall of the device body 1, and the first support plate 11 is used to support the padding plate 16 when it is in a horizontal state. A bracket 12 is fixed to the side of the first support plate 11 close to the rotating disk 2, and a worm 13 meshing with the worm gear 17 is rotatably connected in the bracket 12, and the cooperation between the worm gear 17 and the worm gear 13 is used to drive the padding plate 16 to rotate. A second disc 14 is fixed to one end of the worm gear 13, and a plurality of second magnets 10 are fixed to the side of the second disc 14 close to the rotating disk 2. A transmission cavity 7 is provided in the rotating disk 2, and a round shaft 52 is rotatably connected in the transmission cavity 7. One end of the lead screw 6 rotates and extends into the transmission chamber 7, and one end of the lead screw 6 and the circular shaft 52 are meshed and transmitted by two gears. A side of the rotating disk 2 close to the first support plate 11 is provided with a clearance groove 8, and one end of the circular shaft 52 rotates and extends into the clearance groove 8 and is fixed with a first disc 53, and one side of the first disc 53 is fixed with a plurality of first magnets 9. Multiple first magnets 9 cooperate with multiple second magnets 10 to generate magnetic attraction, and the magnetic attraction between the second magnet 10 and the first magnet 9 can make the first disc 53 drive the second disc 14 to rotate, so that the padding plate 16 can be rotated to a vertical or horizontal state. When the placement rack is placed in the equipment body 1, the lead screw 6 drives the worm 13 to rotate through the cooperation of the first magnet 9 and the second magnet 10, and the padding plate 16 is rotated to a horizontal state, which is convenient for the placement rack to be placed in the equipment body 1.

[0030] In actual operation, when the placement rack needs to be placed, the lead screw 6 rotates, driving the circular shaft 52 to rotate through gear transmission, and the first disc 53 on the circular shaft 52 rotates accordingly, and the first magnet 9 and the second magnet 10 generate magnetic attraction, driving the second disc 14 to drive the worm 13 to rotate, and the worm 13 meshes with the worm wheel 17 to rotate the rotating shaft 15, thereby rotating the pad 16 to a horizontal state, providing stable support for the placement of the placement rack. After the placement rack is placed, the lead screw 6 continues to rotate, and the magnetic attraction cooperates to rotate the pad 16 to a vertical state, making room for subsequent coating operations.

[0031] refer to Figure 2 and Figure 3 The bottom inner wall of the device body 1 is rotatably connected with a first gear 4 through a bearing. The outer wall of the rotating disk 2 is fixedly sleeved with a gear ring 3 meshing with the first gear 4. When the device is running, the first gear 4 is driven to rotate by an external power source (such as a motor), and the first gear 4 meshes with the gear ring 3, thereby driving the rotating disk 2 to rotate. This driving method has a simple structure and high transmission efficiency, and can make the rotating disk 2 rotate stably, providing a stable rotating platform for coating the hook body 42.

[0032] Reference Figure 1 、 Figure 2 and Figure 4 ,On one side of the equipment main body 1 close to the bin door, two second support plates 48 are fixed by welding or bolts. The second support plates 48 are at the same height as the first support plates 11. When the laying plate 16 is placed horizontally, the second support plates 48 can support the laying plate 16. When the laying plate 16 is placed horizontally, its top is flush with the top of the rotating disk 2. In this way, when the crochet hook body 42 is placed on the laying plate 16 for pretreatment or operation, it can ensure that the height of the crochet hook body 42 is the same as the placement position height on the rotating disk 2, which is convenient for subsequently transferring the crochet hook body 42 to the rotating disk 2 for coating operation.

[0033] Refer to Figure 9 、 Figure 11 and Figure 12 ,The placement rack further includes a plurality of rotating cylinders 37 rotatably penetrating through the fixed disk 36. A plurality of groups of placement members arranged vertically are fixed on the outer wall of the rotating cylinder 37. The placement members are composed of a plurality of second limiting rods 41, and the second limiting rods 41 are used for placing the crochet hook body 42. In practical applications, the crochet hook body 42 is placed between the second limiting rods 41. By the rotation of the rotating cylinder 37, the crochet hook body 42 is driven to revolve, providing conditions for the coating operation.

[0034] In order to enable all the crochet hook bodies 42 to be coated in all directions without dead angles in the placement rack, a jolting structure is provided in the fixed disk 36 and the fixed column 31. The jolting structure can drive the crochet hook bodies 42 to move up and down when the crochet hook bodies 42 are being coated, exposing the blocked parts.

[0035] Reference Figure 11 and Figure 12 ,The outer walls of a plurality of rotating cylinders 37 are all rotatably sleeved with first limiting rods 40 through rotating bearings. One ends of a plurality of first limiting rods 40 are fixedly connected to the fixed column 31 by welding or bolts. The outer ring of the rotating bearing is fixedly connected to the rotating cylinder 37, and the inner ring is fixedly connected to the first limiting rod 40.

[0036] During the operation of the equipment, when the rotating cylinder 37 needs to rotate self, the first limiting rod 40 can ensure the stability of the rotating cylinder 37 during self-rotation. Since the first limiting rod 40 is fixedly connected to the fixed column 31, a stable support point is provided for the rotating cylinder 37, preventing the rotating cylinder 37 from shaking or shifting during self-rotation, so as to ensure that the crochet hook body 42 can rotate stably driven by the rotating cylinder 37 and ensure the uniformity of the coating.

[0037] Refer to Figure 9 、 Figure 11 and Figure 12, the jolting structure includes a plurality of second gears 38 rotatably disposed on the top of the fixed disk 36, and the plurality of second gears 38 are respectively fixedly connected to the top end of the rotating cylinder 37. A rotating column 32 rotatably penetrates through the fixed column 31, the top end of the rotating column 32 rotatably penetrates through the fixed disk 36, and a third gear 39 is fixedly attached to the outer wall of the rotating column 32 above the fixed disk 36 by bolts. The second gear 38 meshes with the third gear 39. When the fixed column 31 drives the fixed disk 36 and the rotating cylinder 37 to rotate, the meshing between the second gear 38 and the third gear 39 can drive the second gear 38 to rotate on its own axis. A plurality of chute groups are provided in the rotating cylinder 37. Each chute group is composed of a plurality of through slots 44. A drag plate 45 is slidably connected to the outer wall of the rotating cylinder 37 through the chute group. The drag plate 45 is located below the adjacent second limiting rods 41 and is used to push the hook needle body 42 to move up and down later. A transmission rod 43 is longitudinally slidably connected in the rotating cylinder 37, and the drag plate 45 is fixed to the outer wall of the transmission rod 43. A top disk 47 is fixedly attached to the top of the fixed disk 36 by bolts. The top end of the transmission rod 43 sequentially penetrates through the second gear 38 and the top disk 47. A reciprocating thread section 46 is provided on the outer wall of the transmission rod 43, and the transmission rod 43 is threadedly connected to the top disk 47 through the reciprocating thread section 46.

[0038] In actual operation, the rotating disk 2 drives the chassis 29 and the fixed column 31 thereon to rotate. The rotating column 32 remains stationary under the extrusion of the positioning column 34, and the third gear 39 fixed to the outer wall of the rotating column 32 meshes with the second gear 38. When the fixed column 31 drives the fixed disk 36 to rotate, the second gear 38 drives the rotating cylinder 37 to rotate on its own axis under the action of the third gear 39, driving a plurality of hook needle bodies 42 placed in the second limiting rods 41 to revolve around the rotating cylinder 37 to perform the coating operation. In addition, the transmission rod 43 is slidably engaged with the rotating cylinder 37, and the rotating cylinder 37 synchronously drives the transmission rod 43 to rotate. The transmission rod 43 is threadedly connected to the top disk 47 through the reciprocating thread section 46. Therefore, when the transmission rod 43 rotates, it can move up and down reciprocally. When the reciprocating thread section 46 drives the drag plate 45 to move upward, it can lift the hook needle body 42 by a certain distance, exposing the part of the hook needle body 42 blocked by the second limiting rod 41 for coating. Therefore, the hook needle body 42 can be evenly coated in all directions, ensuring the uniformity of the coating.

[0039] In practical applications, when the rotating disk 2 drives the fixed column 31 to rotate, the third gear 39 remains stationary. Through the meshing action, the second gear 38 drives the rotating cylinder 37 to rotate on its own axis, and the hook needle body 42 revolves accordingly. At the same time, the transmission rod 43 rotates under the drive of the rotating cylinder 37. Due to the threaded connection between the reciprocating thread section 46 and the top disk 47, the transmission rod 43 moves up and down reciprocally, and the drag plate 45 pushes the hook needle body 42 to move up and down, enabling all parts of the hook needle body 42 to obtain a uniform coating, improving the quality and efficiency of the coating.

[0040] Through the above specific embodiments, the device for preparing the low-temperature titanium nitride coating for textile crochet hooks can achieve the stable rotation of the receiving structure, the reasonable placement of the placement rack, and the all-round coating operation of the jolting structure, achieving the expected design effect.

[0041] Reference Figure 3 and Figure 10 , a fixing cylinder 33 is fixed to the inner wall of the top of the device main body 1 by welding or bolts. The fixing cylinder 33 is a hollow structure, a positioning column 34 slides through the fixing cylinder 33, and the bottom end of the positioning column 34 extends below the fixing cylinder 33. A second spring 35 is fixed between the top end of the positioning column 34 and the inner wall of the top of the fixing cylinder 33. The positioning column 34 cooperates with the top end of the rotating column 32, and the specific cooperation method is that the bottom end of the positioning column 34 contacts and applies pressure to the top end of the rotating column 32.

[0042] During the operation of the device, when the chassis 29 and the fixing column 31 rotate, since the positioning column 34 applies pressure to the rotating column 32 under the action of the second spring 35, the rotating column 32 can maintain a stationary state. This design facilitates the later all-round and uniform coating of multiple crochet hook bodies 42, because when the rotating column 32 is stationary, the installation and positioning of the crochet hook bodies 42 are more stable and will not shift due to the rotation of the rotating column 32, thus ensuring that the coating can evenly cover the surface of the crochet hook bodies 42.

[0043] Through the above specific embodiments, the device can realize the automatic loading and unloading of textile crochet hooks and the preparation of a comprehensive and uniform low-temperature titanium nitride coating, improving the production efficiency and coating quality.

[0044] The device main body 1 is a magnetron sputtering coating device.

[0045] Embodiment 2: Reference Figure 13 , on the basis of Embodiment 1, an improvement is made: a plurality of rotating platforms 49 rotate through the inside of the carriage 45, and the rotating platforms 49 are located below the crochet hook bodies 42. A fixing shaft 50 is fixed to the bottom of the rotating platform 49, and a fan blade 51 is fixed to the outer wall of the fixing shaft 50 by screws.

[0046] During the operation of the device, the transmission rod 43 drives the carriage 45 to move up and down reciprocally. When the carriage 45 moves up and down, the fan blade 51 cooperates with the gas inside the device main body 1. Since the gas can generate a driving force on the fan blade 51 when flowing on the surface of the fan blade 51, the fan blade 51 and the fixing shaft 50 rotate self - clockwise. When the carriage 45 moves upward and the rotating platform 49 contacts the bottom end of the crochet hook body 42, since the crochet hook body 42 has a light mass, the rotating platform 49 can drive the crochet hook body 42 to rotate and change the orientation direction of the crochet hook body 42.

[0047] This design can ensure the uniformity of the coating. During the reciprocating movement of the carriage 45 up and down, the crochet hook body 42 is continuously driven to rotate by the rotating table 49, so that all surfaces of the crochet hook body 42 can come into full contact with the coating material, thereby forming a uniform low-temperature titanium nitride coating on the surface of the crochet hook body 42. At the same time, the fan blade 51 is fixed by screws, which facilitates the disassembly and replacement of the fan blade 51. When the fan blade 51 is damaged or needs to be adjusted, maintenance and adjustment can be carried out conveniently.

[0048] A method for using a device for preparing a low-temperature titanium nitride coating for a textile crochet hook, comprising the following steps: S1. Before use, replace the target in the device main body 1 with a high-purity titanium target. When placing a plurality of crochet hook bodies 42 on the placement rack, just pass the plurality of crochet hook bodies 42 through the second limiting rod 41 respectively, and the protruding part at one end of the crochet hook body 42 can be placed on the top of the second limiting rod 41, then the placement of the crochet hook body 42 is completed. At this time, the carriage 45 is located below the crochet hook body 42. S2. When placing the placement rack into the device main body 1, drive the lead screw 6 to rotate through the motor. The moving seat 18 moves towards the door of the device main body 1 under the action of the lead screw 6. When the lead screw 6 rotates, it drives the first disc 53 to rotate through the meshing between gears. The first disc 53 and the second disc 14 can be driven through the magnetic attraction between the first magnet 9 and the second magnet 10. The first disc 53 drives the worm 13 to rotate through the second disc 14. The cooperation between the worm 13 and the worm gear 17 drives the rotating shaft 15 and the laying plate 16 to rotate clockwise until the laying plate 16 is placed on the first support plate 11 and the second support plate 48, and the laying plate 16 is in a horizontal state. Then the placement rack can be placed on the laying plate 16. S3. The placement rack is pushed inward on the cushion plate 16. Since the top of the cushion plate 16 is flush with the rotating disk 2 when the cushion plate 16 is horizontally placed, the placement rack can smoothly move from the cushion plate 16 to the rotating disk 2. When the placement rack moves to the rotating disk 2, until one side of the chassis 29 abuts against the bottom of the moving seat 18, and the chassis 29 can drive the positioning pin 19 to move upward under the action of the inclined surface of the positioning pin 19 until the bottom end of the positioning pin 19 moves to the top of the chassis 29. At this time, the two positioning pins 19 are inserted into the corresponding positioning grooves 30 under the action of the tension spring 20, and the chassis 29 and the moving seat 18 can be fixed. Then the lead screw 6 rotates reversely to move the chassis 29 inward until it moves to the center position of the rotating disk 2. At this time, the top end of the rotating column 32 can abut against the bottom end of the positioning column 34, and the pressure applied by the second spring 35 to the positioning column 34 can increase the friction between the rotating column 32 and the positioning column 34. In addition, the lead screw 6 synchronously drives the worm 13 to rotate reversely, and the worm 13 drives the rotating shaft 15 and the cushion plate 16 to rotate through the worm gear 17 until the cushion plate 16 is in a vertical state and is blocked by the limiting block on one side of the base, ensuring that the cushion plate 16 is in a vertical state (in addition, there is magnetic drive between the first disk 53 and the second disk 14. Therefore, when the cushion plate 16 moves to a vertical or horizontal state, it does not affect the rotation of the lead screw 6); S4. When the placement rack is conveyed to the outside, the lead screw 6 drives the placement rack to move towards the door of the equipment main body 1 through the moving seat 18, and then the lead screw 6 drives the cushion plate 16 to rotate to a horizontal state through the worm 13 until the placement rack moves onto the cushion plate 16. When the moving seat 18 moves to the inner wall of one end of the moving groove 5, the push rod 27 contracts into the rectangular groove 24 due to the obstruction of the inner wall, and the piston plate 26 injects the air in the rectangular groove 24 into the circular groove 22 and drives the ejector rod 23 and the positioning pin 19 to move upward, releasing the clamping connection between the positioning pin 19 and the positioning groove 30, which is convenient for the later staff to take away the placement rack; S5. After the placement rack is automatically placed, the equipment main body 1 starts to operate for coating (the working principle of the coating of the equipment main body 1 is prior art and will not be elaborated here). The first gear 4 is driven to rotate by a motor. The cooperation between the first gear 4 and the toothed ring 3 drives the rotating disk 2 and the placement rack thereon to rotate. Since the positioning post 34 presses the rotating post 32 under the action of the second spring 35, when the rotating disk 2 drives the chassis 29 and the fixed post 31 to rotate, the rotating post 32 remains stationary. The third gear 39 fixed to the outer wall of the rotating post 32 meshes with the second gear 38. When the fixed post 31 drives the fixed disk 36 to rotate, the second gear 38 drives the rotating cylinder 37 to rotate self-driven under the action of the third gear 39, driving a plurality of hook needle bodies 42 placed in the second limiting rod 41 to revolve around the rotating cylinder 37 for coating operation. In addition, the transmission rod 43 is in sliding fit with the rotating cylinder 37, and the rotating cylinder 37 synchronously drives the transmission rod 43 to rotate. The transmission rod 43 is threadedly connected to the top plate 47 through the reciprocating thread section 46. Therefore, when the transmission rod 43 rotates, it can move up and down reciprocally. When the reciprocating thread section 46 drives the drag plate 45 to move upward, it can lift the hook needle body 42 up a certain distance, exposing the part of the hook needle body 42 blocked by the second limiting rod 41 for coating. Therefore, the hook needle body 42 can be coated evenly in all directions, ensuring the uniformity of the coating. S6. In addition, when the transmission rod 43 drives the drag plate 45 to move up and down reciprocally, the fan blade 51 contacts the gas inside the equipment main body 1, and when the gas flows on the surface of the fan blade 51, it can generate a driving force on the fan blade 51, causing the fan blade 51 and the rotating table 49 to rotate. When the drag plate 45 moves upward and the rotating table 49 contacts the bottom end of the hook needle body 42, since the hook needle body 42 has a light mass, the rotating table 49 can drive the hook needle body 42 to rotate, changing the orientation direction of the hook needle body 42 to ensure the uniformity of the coating.
