Description

Technical Field

[0001] The invention relates to the field of quenching equipment, in particular to a metal knitting needle quenching equipment and a quenching process. Background Art

[0002] Knitting needles are an important component of textile machines. They are mainly used to weave yarn into coils and nest multiple coils to form knitted fabrics. During the working process, the knitting needles are in direct contact with the yarn and drive the yarn to deform. Therefore, the physical properties of the knitting needles, such as hardness, wear resistance and smoothness, will directly affect the product quality of the knitted fabrics. In order to improve the hardness and wear resistance of the knitting needles, the knitting needles will be quenched during the production process.

[0003] Related technologies can refer to the Chinese patent with announcement number CN216786211U, which discloses a knitting needle quenching device, including a box, a cooling system, a heating system, a conveying system, an atmosphere system, a control system and a clamp; the cooling system is located on one side of the box, and the cooling system has a quenching medium; the heating system is arranged on the box, and the heating system has a heating element for heating the knitting needles, and the output end of the heating system is inserted into the quenching medium of the cooling system; the conveying system is arranged on the box and located in the heating system to convey the knitting needles through the heating system; the atmosphere system is arranged on the box, and the atmosphere system provides protective gas to the heating system; the control system is connected with the cooling system, the heating system, and the conveying system and controls the cooling system, the heating system, and the conveying system to work, and the clamp is used to fix multiple knitting needles, and the clamp is placed in the conveying system to convey the knitting needles. The quenching device is sealed during the heating process, which is conducive to improving the yield rate of knitting needles, improving the hardness and wear resistance of knitting needles, and extending the service life of knitting needles.

[0004] Regarding the above-mentioned related technologies, since the knitting needles are slender parts, if the knitting needles are heated unevenly during the heating process, it is easy to cause the knitting needles to deform. When the knitting needles are driven to move in the heating system through the transmission system, the heating elements located below the transmission system are blocked by the transmission system. Therefore, the heat generated by them will inevitably be lost when radiating to the knitting needles, and the heat generated by the heating elements above the transmission system will be directly radiated to the clamp and the knitting needles. At this time, if the heat generated by the heating elements on both sides when working is the same, the heat radiation received by the knitting needles will be uneven, which can easily cause the knitting needles to deform. The heat generated by the heating elements when working is difficult to accurately control, and it is not easy to control the heat generation efficiency of the heating elements according to the heat loss. Therefore, a quenching device is urgently needed to improve the heating uniformity of the knitting needles during quenching and improve the quenching quality of the knitting needles. Summary of the invention

[0005] In order to improve the uniformity of heating of knitting needles during quenching and enhance the quenching quality of knitting needles, the present application provides a metal knitting needle quenching device and a quenching process.

[0006] In the first aspect, the present application provides a metal knitting needle quenching device, which adopts the following technical solution:

[0007] A metal knitting needle quenching device comprises a frame: a heating box and a cooling box are sequentially arranged at the upper end of the frame along the length direction, a plurality of heating elements for heating the knitting needles are arranged in the heating box, and the frame is also provided with a conveyor belt, which passes through the heating box and the cooling box in sequence; it also comprises: a plurality of carrying boxes, the conveyor belt is used to drive the carrying boxes to move, a plurality of driving blocks are arranged along the length direction of the carrying boxes, the upper ends of the driving blocks are connected with two disc blocks for vertical rotation, the carrying boxes are provided with clamping members for driving the two disc blocks to approach or move away from each other, a clamping plate for clamping the knitting needles is fixedly arranged on the outer circle of the disc blocks, the carrying box is provided with a rotating member for driving the disc blocks to rotate, when the rotating member is working, the clamping plate switches between a horizontal state and a vertical state, the plurality of heating elements are divided into two groups, the two groups of heating elements are both at the upper end of the conveyor belt, and all the heating elements in the same group are in the same straight line, the gap between the two groups of heating elements constitutes a heating channel, and when the clamping plate is in a vertical state, the knitting needles are directly opposite to the heating channel.

[0008] By adopting the above technical solution, the two disc blocks on the same driving block form a group, and the knitting needles are placed one by one between the two clamping plates of the same group of disc blocks, and the two clamping plates are driven by the clamping member to cooperate to clamp and position the knitting needles. The carrier box that has transferred the knitting needles is placed at the head end of the conveying direction of the conveyor belt, and the carrier box is driven by the conveyor belt to move toward the heating box. When placing the knitting needles, the knitting needles are placed horizontally, thereby reducing the probability of the knitting needles scratching the operator or touching other equipment during the placement of the knitting needles. After the carrier box is placed on the conveyor belt, the disc block is driven to rotate by the rotating member, so that the disc block drives the knitting needles to rotate from the horizontal state to the vertical state through the clamping plate. When the knitting needles rotate to the vertical state, the knitting needles are directly opposite to the heating channel. The carrying box drives the knitting needles to pass through the heating channel in sequence. At this time, the knitting needles are between two groups of heating elements, and the heating elements heat and quench the knitting needles. After heating, the conveyor belt drives the carrying box out of the heating box and into the cooling box, and the knitting needles are cooled by the cooling box to complete the quenching process. During the quenching process, the distances from both sides of the knitting needles to the heating elements are the same, which improves the uniformity of heating the knitting needles. When the knitting needles are in a vertical state, the direction in which they bear gravity is the same as the length direction of the knitting needles, thereby reducing the probability of deformation of the knitting needles due to gravity after they are heated and softened, and improving the quality of the knitting needle quenching process.

[0009] Optionally, the clamping member includes a bidirectional screw and two movable rings, a rotating rod is fixedly provided on the upper end of the driving block, the rotating rod is arranged along the length direction of the carrying box, and the rotating rod passes through the disc block and rotates coaxially with the disc block, the movable ring corresponds to the disc block one by one, the movable ring is sleeved on the outside of the disc block and rotates coaxially with the disc block, the bidirectional screw is located between the two movable rings, and the two ends of the bidirectional screw respectively pass through the two movable rings and are threadedly connected to the movable rings, and a support plate for supporting the rotation of the bidirectional screw is provided on the upper end of the carrying box.

[0010] By adopting the above technical solution, under the support of the support plate, when the bidirectional lead screw rotates, it drives the two movable rings to move closer to or away from each other. When the movable ring moves, it drives the disc block to move along the axis of the rotating rod, so that the disc block drives the clamping plate to clamp the knitting needle, or release the clamping of the knitting needle.

[0011] Optionally, the carrying box is fixedly provided with a plurality of isolation plates along the length direction, and the gaps between adjacent isolation plates constitute cavities. The driving blocks correspond one-to-one to the cavities. The driving blocks are all located in the cavities and are slidingly connected to the isolation plates along the width direction of the carrying box. A push plate is provided on one side of the carrying box along the width direction, and the push plate is fixedly provided with push rods corresponding one-to-one to the driving blocks. The push rods pass through the carrying box and are fixedly connected to the corresponding driving blocks.

[0012] By adopting the above technical solution, the isolation plate isolates the knitting needles in the carrier box, so that gaps are formed between adjacent knitting needles, thereby improving the convenience of placing the knitting needles in the carrier box. At the same time, all driving blocks are driven to move by the push plate, thereby facilitating the adjustment of the position of the driving blocks and the knitting needles after entering the heating channel.

[0013] Optionally, the rotating part includes a counterweight block, a baffle and an blocking block, the counterweight block is fixedly connected to the disc block and is eccentrically arranged relative to the center of the disc block, the baffle is located on the side of the disc block close to the isolation plate, and the baffle, the counterweight block and the center of the disc block are located in the same straight line, the blocking block is fixedly connected to the isolation plate along the length direction of the isolation plate, a avoidance opening adapted to the baffle is provided on the side of the blocking block close to the push plate, and a support block is fixedly provided on the upper end of the carrier box, and when the baffle is located in the avoidance opening and the counterweight block is at the lowermost end of the disc block, the clamping plate contacts the support block and is in a horizontal state.

[0014] By adopting the above technical scheme, in the initial state, the baffle is located in the avoidance opening and has no contact with the blocking block, and the counterweight block is at the lower end of the disc block under the action of gravity. At this time, the baffle is at the upper end of the disc block and is directly opposite to the blocking block, so that the clamping plate is in contact with the support block and is in a horizontal state, and the knitting needle is placed on the support block. After the knitting needle is clamped by the clamping plate, the push plate is operated to push the driving block to move, so that the driving block drives the disc block to move from the avoidance opening to the blocking block. When the baffle contacts the blocking block, the disc block continues to move, so that the baffle drives the disc block to rotate, and the baffle rotates to the bottom of the blocking block and fits with the blocking block. At this time, the disc block drives the clamping plate to rotate to a vertical state.

[0015] Optionally, a positioning groove is provided at the lower end of the carrier box, and a positioning block adapted to the positioning groove is fixedly provided along the circumference of the conveyor belt, and the positioning block fits with the inner wall of the positioning groove when inserted into the positioning groove.

[0016] By adopting the above technical solution, the positioning block cooperates with the positioning groove, which is beneficial to improving the connection stability between the conveyor belt and the carrier box and reducing the probability of the carrier box being deflected on the conveyor belt.

[0017] Optionally, both ends of the heating box along the length direction are fixedly provided with heat insulation plates, and the side of the heat insulation plate away from the cooling box is fixedly connected with a conveying pipe connected to the heating box, the length of the conveying pipe is greater than the length of the supporting box, and both ends of the heat insulation plate along the length direction are vertically hinged with insulation doors, and the frame is provided with an adjusting member for driving the push plate to approach or move away from the supporting box, and the adjusting member is located inside the heating box.

[0018] By adopting the above technical solution, driven by the conveyor belt, when the carrier box enters the conveying tube, the heat insulation door at one end of the conveying tube is pushed to open. After the carrier box is separated from the heat insulation door, the heat insulation door is closed, and the heat insulation board and the heat insulation door cooperate to seal the heating box, thereby reducing the heat loss in the heating box. Before the carrier box passes through the conveying tube, the push plate is located away from the carrier box. At this time, the knitting needles are in a horizontal state, thereby reducing the demand for the height space of the conveying tube and reducing the probability of heat diffusion from the conveying tube. At the same time, when the carrier box enters the heating box, the push plate is driven close to the carrier box through the adjusting member, so that the knitting needles are erected, which is convenient for heating and quenching the knitting needles.

[0019] Optionally, the adjusting member includes two baffles and a guide plate, the two baffles are located in the heating box and are fixedly connected to the heating box, the conveyor belt passes between the two baffles and fits with the baffles, the guide plate is fixedly connected to any baffle, and when the carrying box is located on the conveyor belt, the push plate is opposite to the guide plate, and a guide column is vertically fixed to the upper end of the push plate, and a guide groove adapted to the guide column is opened along the length direction of the guide plate, and the guide plate drives the guide column to approach or move away from the carrying box through the guide groove.

[0020] By adopting the above technical solution, the frame supports the guide plate through the baffle. In the initial state, the push plate is in a position away from the carrier box. When the carrier box is placed on the conveyor belt, the guide column is opposite to the guide groove on the guide plate. After the guide column enters the guide groove, the guide plate limits the guide column through the guide groove. When the guide column moves along the guide groove, it moves along the guide groove, thereby driving the push plate to approach or move away from the carrier box.

[0021] In a second aspect, the present application provides a quenching process using a metal knitting needle quenching device, which adopts the following technical solution:

[0022] A metal knitting needle quenching device and quenching process, comprising the following steps:

[0023] Boxing: Put the knitting needles into the carrying box one by one, so that the knitting needles are between two adjacent clamping plates, and the two disc blocks are driven close to each other through the clamping piece, so that the disc blocks clamp the knitting needles through the clamping plates;

[0024] Positioning: During the boxing process, the knitting needles are placed horizontally for easy clamping and placement. After the boxing is completed, the clamping plate is driven from a horizontal state to a vertical state by the rotating part;

[0025] Transportation: Place the carrier boxes one by one on the conveyor belt, so that the conveyor belt drives the carrier boxes to move toward the heating box;

[0026] Heat treatment: After the conveyor belt drives the carrier box into the heating box, the knitting needles are in the heating channel and are heated and quenched by the heating element;

[0027] Cooling: The carrier box is moved out of the heating box by a conveyor belt, so that the carrier box drives the knitting needles into the cooling box for cooling.

[0028] In summary, the present application includes at least one of the following beneficial technical effects:

[0029] 1. The two disc blocks on the same driving block form a group. Place the knitting needles one by one between the two clamping plates of the same group of disc blocks, and drive the two clamping plates to clamp and position the knitting needles through the clamping parts. Place the carrier box with the knitting needles transferred to the head end of the conveying direction of the conveyor belt, and drive the carrier box to move toward the heating box through the conveyor belt. When placing the knitting needles, place them horizontally, thereby reducing the probability of the knitting needles scratching the operator or touching other equipment during the placement of the knitting needles. After placing the carrier box on the conveyor belt, drive the disc block to rotate through the rotating part, so that the disc block drives the knitting needles to rotate from the horizontal state to the vertical state through the clamping plate. When the knitting needles rotate to the vertical state, the knitting needles are directly opposite to the heating channel. The carrier box drives the knitting needles to pass through the heating channel in sequence. At this time, the knitting needles are between the two sets of heating elements. The heating elements heat and quench the knitting needles. After heating, the conveyor belt drives the carrier box out of the heating box and into the cooling box. The knitting needles are cooled by the cooling box to complete the quenching process. During the quenching process, the distances between the two sides of the knitting needles and the heating elements are the same, which improves the uniformity of heating the knitting needles. When the knitting needles are in a vertical state, the direction in which they bear gravity is the same as the length direction of the knitting needles, thereby reducing the probability of deformation of the knitting needles due to gravity after they are heated and softened, and improving the quality of the knitting needle quenching process.

[0030] 2. In the initial state, the baffle is located in the avoidance opening and has no contact with the blocking block. The counterweight block is at the lower end of the disc block under the action of gravity. At this time, the baffle is at the upper end of the disc block and is opposite to the blocking block, so that the clamping plate is in contact with the support block and is in a horizontal state. The knitting needles are placed on the support block. After the knitting needles are clamped by the clamping plate, the push plate is operated to push the driving block to move, so that the driving block drives the disc block to move from the avoidance opening to the blocking block. When the baffle contacts the blocking block, the disc block continues to move, so that the baffle drives the disc block to rotate. After the baffle rotates to the bottom of the blocking block, it fits the blocking block. At this time, the disc block drives the clamping plate to rotate to a vertical state.

DETAILED DESCRIPTION

[0038] The present application is further described in detail below in conjunction with all the accompanying drawings.

[0039] The present application discloses a metal knitting needle quenching device and a quenching process Example

[0040] Reference Figure 1 and Figure 2 A metal knitting needle quenching device includes a frame 1. A heating box 2 and a cooling box 3 are sequentially installed on the upper end of the frame 1 along the length direction. A plurality of heating elements 21 are installed in the heating box 2. The plurality of heating elements 21 are divided into two groups. All heating elements 21 in the same group are arranged along the length direction of the heating box 2. The gap between the two groups of heating elements 21 constitutes a heating channel. A refrigeration system is provided in the cooling box 3. In this embodiment, the refrigeration system is air-cooled. Liquid cooling can also be used in other embodiments. The specific setting is based on actual needs. The refrigeration system is a prior art, so no further details will be given here. A conveyor belt 4 is installed on the upper end of the frame 1 along the length direction. The conveyor belt 4 passes through the heating box 2 and the cooling box 3 in sequence, and the conveyor belt 4 is located directly below the heating channel.

[0041] Reference Figure 1 and Figure 2 The heating box 2 is fixedly connected with heat insulation boards 22 at both ends along the length direction. The heat insulation boards 22 are conducive to reducing the open area where the heating box 2 is connected to the outside world, thereby reducing the heat diffusion of the heating box 2. The heat insulation board 22 is provided with a conveying port, and the upper end of the conveyor belt 4 passes through the conveying port. A conveying pipe 23 is fixedly provided on the side of the heat insulation board 22 away from the cooling box 3. The conveying pipe 23 is connected to the conveying port. Both ends of the conveying pipe 23 along the length direction are vertically hinged with heat insulation doors 231. Under the action of gravity, the heat insulation door 231 is in a vertical state in a natural state. At this time, the lower end of the heat insulation door 231 is close to the conveyor belt 4, thereby blocking the conveying pipe 23, further reducing the heat diffusion in the heating box 2.

[0042] Reference Figure 3 and Figure 4 The metal knitting needle quenching device also includes a plurality of carrier boxes 5, a placement cavity is provided at the upper end of the carrier box 5, a plurality of driving blocks 51 are arranged in the placement cavity, the plurality of driving blocks 51 are evenly arranged along the length direction of the carrier box 5, and the driving blocks 51 are slidably connected to the carrier box 5 along the width direction of the carrier box 5. A plurality of isolation plates 55 are fixedly connected to the carrier box 5 along the length direction, the isolation plates 55 are spaced apart from the driving blocks 51, the gaps between adjacent isolation plates 55 constitute independent cavities, and all driving blocks 51 are located in separate cavities.

[0043] Reference Figure 3 and Figure 4 A push plate 56 is provided on one side of the carrier box 5 along the width direction, and a push rod corresponding to the driving block 51 is fixedly connected to the side of the push plate 56 close to the carrier box 5. The push rod passes through the carrier box 5 and is fixedly connected to the corresponding driving block 51. When the push plate 56 moves, the driving block 51 is driven to move along the width direction of the carrier box 5 through the push rod. When the push plate 56 is at a position away from the carrier box 5, the driving block 51 is at one side of the carrier box 5 along the width direction.

[0044] Reference Figure 3 and Figure 4 The upper end of the driving block 51 is provided with two coaxial disc blocks 52. The driving block 51 is fixedly connected with a rotating rod 511 corresponding to the disc blocks 52. The rotating rod 511 passes through the corresponding disc block 52 and rotates coaxially with the disc block 52. The driving block 51 supports the disc block 52 through the rotating rod 511, so that the disc block 52 is driven to move when the driving block 51 moves. The upper end of the driving block 51 is also provided with a clamping member 53, which includes a bidirectional lead screw 531 and two moving rings 532. The moving rings 532 correspond to the disc blocks 52 one by one. The outer side of the disc block 52 is provided with an annular groove adapted to the moving ring 532 along the circumferential direction. The moving ring 532 is located in the annular groove and is rotatably connected to the disc block 52 along the circumferential direction.

[0045] Reference Figure 3 and Figure 4 A support plate 512 is fixedly disposed on the upper end of the driving block 51. When the driving block 51 moves, the support plate 512 is driven to move. The bidirectional lead screw 531 passes through the support plate 512 and is rotatably connected to the support plate 512. The bidirectional lead screw 531 is located between the two moving rings 532, and the two ends of the bidirectional lead screw 531 pass through the two moving rings 532 and are threadedly connected to the moving rings 532. When the bidirectional lead screw 531 rotates, the two moving rings 532 are driven to move closer to or farther from each other. When the moving ring 532 moves, the disc block 52 is driven to move along the axis direction of the rotating rod 511.

[0046] Reference Figure 4 and Figure 5A clamping plate 521 is fixedly connected to the outer circumference of the disc block 52. The clamping plate 521 is located on the side where the two disc blocks 52 are close to each other. When the disc block 52 moves, the clamping plate 521 is driven to move. Support blocks 57 are provided between adjacent isolation plates 55. The support blocks 57 are arranged along the length direction of the isolation plates 55, and the support blocks 57 are fixedly connected to the carrier box 5. A limiting groove adapted to the knitting needle is opened at the upper end of the support block 57 along the length direction. When the knitting needle is placed in the limiting groove, the support block 57 supports and limits the knitting needle.

[0047] Reference Figure 3 and Figure 4 The two disc blocks 52 on the same driving block 51 are set as a group. In the initial state, the knitting needle is located between the two disc blocks 52 of the same group, and the knitting needle is in the middle of the two clamping plates 521. A plurality of clamping blocks are fixedly connected to the side of the clamping plate 521 away from the disc block 52. The support block 57 is provided with an opening adapted to the clamping block. When the clamping plate 521 is in contact with the support block 57, it is in a horizontal state. At this time, the clamping block is opposite to the opening, and the two disc blocks 52 are driven to approach each other through the clamping member 53, so that the clamping plate 521 clamps and positions the knitting needle through the clamping block. Furthermore, all the bidirectional lead screws 531 on the same carrier box 5 are coaxially connected, and then when any bidirectional lead screw 531 is rotated, the remaining bidirectional lead screws 531 are driven to rotate synchronously.

[0048] Reference Figure 3 and Figure 4 In the initial state, the driving block 51 is located at one side of the carrier box 5 along the width direction, and the knitting needle is in a horizontal state and located in the cavity. The carrier box 5 is provided with a rotating member 54 for driving the disc block 52 to rotate. The rotating member 54 includes a counterweight block 541, a baffle plate 542 and a blocking block 543. The counterweight block 541 is fixedly connected to the disc block 52, and the counterweight block 541 is eccentrically arranged relative to the center of the disc block 52, and the connecting line between the counterweight block 541 and the axis of the disc block 52 is perpendicular to the connecting line between the clamping plate 521 and the axis of the disc block 52. Under the action of gravity, the counterweight block 541 has a tendency to move downward, and the counterweight block 541 drives the disc block 52 to move when it moves. When the counterweight block 541 is at the lower end of the disc block 52, the clamping plate 521 contacts the support block 57 and is in a horizontal state.

[0049] Reference Figure 3 and Figure 4The baffle 542 is located on one side of the disc block 52 close to the isolation plate 55 , and the baffle 542 , the center of the disc block 52 and the counterweight block 541 are in the same straight line. Under the action of the counterweight block 541 , the baffle 542 is located at the upper end of the disc block 52 . The blocking block 543 is fixedly connected to the isolation plate 55 along the length direction of the isolation plate 55. An escape hole is provided at one end of the blocking block 543 close to the push plate 56. When the baffle plate 542 is located in the escape hole, it does not contact the blocking block 543. When the driving block 51 is driven to move to the middle position of the carrier box 5 by the push plate 56, the disc block 52 drives the baffle plate 542 to approach the blocking block 543. After the baffle plate 542 and the blocking block 543 collide, the blocking block 543 drives the disc block 52 to rotate through the baffle plate 542. When the disc block 52 rotates, it drives the baffle plate 542 to move toward the lower end of the blocking block 543. The disc block 52 drives the knitting needle to rotate through the clamping plate 521. When the baffle plate 542 is completely moved to the lower end of the blocking block 543, the knitting needle is in a vertical state. At this time, the push plate 56 is continued to be pushed to move, so as to facilitate the adjustment of the position of the knitting needle.

[0050] Reference Figure 1 and Figure 2 After the knitting needles are loaded into the carrier box 5, the carrier box 5 is placed on the conveyor belt 4. The conveyor belt 4 is evenly fixed with a plurality of positioning blocks 41. The lower end of the carrier box 5 is provided with a positioning groove 58 adapted to the positioning block 41. When the carrier box 5 is placed, the positioning block 41 is inserted into the positioning groove 58, thereby improving the connection stability between the carrier box 5 and the conveyor belt 4 and reducing the probability of the carrier box 5 and the conveyor belt 4 being offset. The conveyor belt 4 drives the carrier box 5 to move toward the heating box 2. When the carrier box 5 contacts the heat insulation door 231, the heat insulation door 231 is pushed open, and the carrier box 5 enters the conveying pipe 23. In the initial state, the push plate 56 is in a position away from the carrier box 5, and all the knitting needles are in a horizontal state, thereby reducing the probability of the knitting needles interfering with the heat insulation door 231. At the same time, the overall height of the carrier box 5 and the knitting needles is reduced, the height requirement for the conveying pipe 23 is reduced, and the heat loss at the conveying pipe 23 is reduced.

[0051] Reference Figure 1 and Figure 3 The length of the conveying pipe 23 is greater than the length of the carrier box 5. When the carrier box 5 contacts any insulating door 231, it always keeps a distance from the other insulating door 231, so that the two insulating doors 231 are opened alternately. The frame 1 is provided with an adjustment member 6, which includes two partitions 61 and a guide plate 62. The two partitions 61 are both located in the heating box 2 and are fixedly connected to the heating box 2. The conveyor belt 4 is located between the two partitions 61 and is in contact with the partitions 61. The guide plate 62 is arranged parallel to the partition 61, and the guide plate 62 is fixedly connected to the partition 61. When the carrier box 5 is located on the conveyor belt 4, the push plate 56 is directly opposite to the guide plate 62.

[0052] Reference Figure 3and Figure 6 In terms of vertical height, the guide plate 62 is located above the push plate 56, and a guide groove 621 is provided at the lower end of the guide plate 62. The guide groove 621 is arranged along the length direction of the guide plate 62, and the guide groove 621 includes two inclined portions and a straight portion. The straight portion is located in the middle of the length direction of the guide plate 62, and the length of the heating channel is less than the length of the straight portion. The two inclined portions are respectively located at the two ends of the straight portion, and gradually approach the partition 61 where the guide plate 62 is located along the direction from the straight portion to the inclined portion.

[0053] Reference Figure 3 and Figure 6 , a guide post 561 is fixed on the upper end of the push plate 56. When the carrier box 5 enters the heating box 2, the guide post 561 is opposite to the end of the inclined portion away from the straight portion. The carrier box 5 continues to move along the conveyor belt 4, so that the guide post 561 enters the inclined portion and approaches the straight portion along the inclined portion. When the guide post 561 enters the straight portion, the push plate 56 is in a position close to the carrier box 5. At this time, the knitting needles are arranged vertically. The carrier box 5 continues to move and drives all the knitting needles to enter the heating channel one by one. The heating element 21 works and heats and quenches the knitting needles. The distance between the heating elements 21 on both sides of the knitting needles and the knitting needles is the same, which is conducive to ensuring the uniformity of heating of the knitting needles and improving the quenching quality of the knitting needles. After heating, the conveyor belt 4 drives the carrier box 5 out of the heating box 2 and continues to drive the carrier box 5 into the cooling box 3 for cooling, thereby completing the entire quenching process.

[0054] The working principle of a metal knitting needle quenching device according to the embodiment of the present application is as follows: the heating box 2 blocks the opening of the heating box 2 connected to the outside world through the heat insulation board 22 and the heat insulation door 231, thereby reducing the heat loss in the heating box 2 and improving the accuracy of controlling the temperature in the heating box 2. The knitting needles are clamped by the clamping plate 521 on the disc block 52, and after the fully loaded carrier box 5 is placed on the conveyor belt 4, the conveyor belt 4 drives the carrier box 5 through the conveying pipe 23 and enters the heating box 2. At this time, the guide plate 62 drives the push plate 56 to approach the carrier box 5 through the guide groove 621, so that the push plate 56 drives the disc block 52 to rotate through the rotating member 54. When the disc block 52 rotates, it drives the knitting needles to rotate from the horizontal state to the vertical state through the clamping plate 521. After the knitting needles rotate to the vertical state, they are directly opposite to the heating channel. The carrier box 5 drives the knitting needles to pass through the heating channel in sequence, and the heating element 21 heats and quenches the knitting needles. After heating, the conveyor belt 4 drives the carrier box 5 to move out of the heating box 2 and enter the cooling box 3, and the knitting needles are cooled by the cooling box 3 to complete the quenching process. During the quenching process, the distance between the two heating elements 21 and the knitting needles is the same, which is conducive to improving the uniformity of heating the knitting needles and improving the quality of the knitting needle quenching process.

[0058] Position adjustment: During the boxing process, the knitting needles are placed horizontally for easy clamping and placement. After the boxing is completed, the rotating member 54 drives the clamping plate 521 from a horizontal state to a vertical state;

[0059] Transportation: placing the carrying boxes 5 one by one on the conveyor belt 4, so that the conveyor belt 4 drives the carrying boxes 5 to move toward the heating box 2;

[0061] Cooling: The carrier box 5 is moved out of the heating box 2 by the conveyor belt 4, so that the carrier box 5 drives the knitting needles into the cooling box 3 for cooling.

[0062] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
