Description

Technical Field

[0001] The invention relates to the field of stamping equipment, and in particular to an integrated sock machine sewing needle preparation device. Background Art

[0002] The felting needle, also known as the needle of the needle punching machine, is mainly used in the production process of non-woven fabrics. It can mechanically reinforce the fiber web to form a non-woven fabric product of a specific shape, such as one-piece socks. The felting needle mainly consists of a needle handle, a needle waist, a needle blade and a needle body. The needle blade part is used to contact the fabric, and the corners of the outer side are prepared with barbed teeth by stamping.

[0003] For related technologies, please refer to the Chinese patent with announcement number CN114535469B, which discloses a needle production device with needle tooth adjustment function. It includes a second support plate, a punching mechanism and a stabilizing mechanism. The punching mechanism for punching the needle teeth is arranged on the front side of the second support plate, and the stabilizing mechanism for supporting the needle is arranged below the punching mechanism. By setting the stabilizing mechanism, the device avoids the needle to be processed from being offset when punching the teeth, so that the teeth on the left and right sides of the left and right needles are different in size. By setting the punching mechanism, the distance between the four punching blocks is increased, so that the device is suitable for large-sized needles to be processed, and the scope of use is improved.

[0004] With respect to the above-mentioned related technologies, when stamping the needle, it is necessary to try to avoid the side edges of the needle from being deformed under the action of the stamping block. Although the upper and lower sides of the needle can be limited by the stabilizing groove plate and the stabilizing groove plate, the probability of the needle bending during stamping can be reduced. However, in order to prevent the stamping block from colliding with the stabilizing groove plate, the width of the stabilizing groove plate needs to be smaller than the width of the needle. Therefore, during the stamping process, the stabilizing groove plate can only support the middle main body of the needle, while the stamping part of the side edge of the needle is still easy to be deformed under the action of the stamping block, especially when processing a needle with dense teeth, the needle has more stamping openings, so the side edge of the needle is more likely to be deformed under the action of the stamping block, affecting the stamping quality of the needle. Summary of the invention

[0005] In order to improve the stamping processing quality of needles, the present application provides an integrated sock machine sewing needle preparation device.

[0006] The present application provides an integrated sock machine sewing needle preparation device, which adopts the following technical solution:

[0007] An integrated sock machine sewing needle preparation device comprises a punching frame, wherein a conveying member for the needle is arranged along the length direction at the upper end of the punching frame, and further comprises: a first clamping member arranged on one side of the conveying member, and when the conveying member drives the needle to move to the first clamping member, the first clamping member clamps and positions the end of the needle, and the punching frame is also provided with a rotating member for driving the first clamping member to rotate; a punching block is located at the upper end of the punching frame and reciprocates vertically, and after the first clamping member clamps the needle, the side edge of the needle to be punched is located below the punching block, and the punching frame is provided with an adjusting member for adjusting the position of the punching block in the horizontal and longitudinal directions; a rod support member is located below the punching block and is staggered with the punching block, and the punching frame is provided with a driving member for driving the rod support member to move vertically. The movable part, the upper end part of the rod support part is provided with an inclined surface, after the first clamping part clamps and positions the needle, the lower end surface of the needle needle is parallel to the inclined surface, the rod support part is slidably connected with a support plate along the inclination direction of the inclined surface, the rod support part is provided with a locking part for positioning the support plate, the angle between the end surface of the support plate close to the stamping block and the inclined surface is the same as the angle between the two adjacent end surfaces of the needle needle; the side edge support part is located below the stamping block and is slidably connected to the support part along the longitudinal direction, the upper end surface of the side edge support part is flush with the inclined surface, the side edge support part is vertically provided with an avoidance opening facing the stamping block, a longitudinal connecting part is provided between the side edge support part and the stamping block, and when the stamping block moves along the longitudinal direction, the side edge support part is driven to move synchronously through the longitudinal connecting part.

[0008] By adopting the above technical solution, under the support of the stamping frame, the needles are transported one by one to the first clamping member through the conveying member, and the first clamping member clamps and positions the needles so that one side edge of the needle is directly below the stamping block. The position of the stamping block is adjusted in advance by the adjusting member according to the size of the needles so that the stamping block is opposite to the side edge of the positioned needles. The punching block moves downward vertically, and the driving member drives the rod support member to rise until the inclined surface of the rod support member contacts the needle. At this time, the support plate fits the end surface of the needle away from the punching block, thereby supporting the needle, and the position of the support plate is adjusted in advance by the locking member according to the specifications of the needle, so that when the support plate supports the needle, the side edges of the needle to be processed are all located outside the rod support member. At this time, the side edge support member supports the side edges that need to be punched. During punching, the side edge support member avoids the punching block through the avoidance opening. When the punching block moves along the length direction of the needle, the side edge support member is driven to move synchronously through the longitudinal connecting member, thereby facilitating the punching of needles of different densities. When processing different side edges of the needle, the first clamping member and the needle are driven to rotate by the rotating member to move the unprocessed side edge to move below the punching block. During the stamping process of the needle, the shaft support supports and positions the entire needle, reducing the probability of the needle bending, and the side edge support supports the side edge of the needle that needs to be processed, thereby reducing the probability of the side edge of the needle being deformed during the stamping process, which is beneficial to improving the stamping processing quality of the needle.

[0009] Optionally, the conveying member includes an upper conveyor belt and a lower conveyor belt, the lower conveyor belt is arranged along the length direction of the stamping frame, the upper conveyor belt is located directly above the lower conveyor belt and is parallel to the lower conveyor belt, the stamping frame is provided with a support frame for driving the upper conveyor belt and the lower conveyor belt to move closer to or away from each other, and the gap between the upper conveyor belt and the lower conveyor belt constitutes a conveying channel for transporting needles, and when the needle is located in the conveying channel, it is perpendicular to the length direction of the upper conveyor belt.

[0010] By adopting the above technical solution, the punching frame supports the upper conveyor belt and the lower conveyor belt through the support frame, so that the gap between the upper conveyor belt and the lower conveyor belt is adapted to the diameter of the needle. When the needle needs to be processed, the needle is placed between the upper conveyor belt and the lower conveyor belt. The upper conveyor belt and the lower conveyor belt cooperate to clamp the needle and move the needle along the conveying channel, thereby realizing automatic loading of the needle. By adjusting the distance between the upper conveyor belt and the lower conveyor belt, it is beneficial to increase the conveying range of the conveyor, which is suitable for processing needles of different diameters.

[0011] Optionally, the first clamping member includes a positioning plate, a movable plate and two groups of clamping blocks. The positioning plate is rotatably connected to the stamping frame along the vertical direction, the movable plate is located on the side of the positioning plate away from the conveying member, the stamping frame has a pushing member that slides back and forth along the axial direction of the movable plate, the movable plate is rotatably connected to the pushing member and moves with the pushing member, the two groups of clamping blocks are located on the side of the positioning plate close to the conveying member and are slidably connected to the positioning plate along the diameter direction of the positioning plate, a connecting rod is hinged on the side of the clamping block close to the movable plate, the end of the connecting rod away from the positioning plate is hinged to the movable plate, and the rotating member is fixedly connected to the stamping frame, for driving the positioning plate and the movable plate to rotate.

[0012] By adopting the above technical solution, in the initial state, the movable disk is in a position away from the positioning disk. At this time, the two clamping blocks are away from each other and distributed vertically. When the conveying member drives the needle to enter between the two clamping blocks, the movable disk is driven close to the positioning disk through the pushing member. When the movable disk moves, the two clamping blocks are driven close to each other through the two connecting rods. The two clamping blocks cooperate to clamp and position the needle. When the needle needs to be rotated, the positioning disk and the movable disk are driven to rotate through the rotating member, thereby driving the needle to rotate.

[0013] Optionally, a positioning plate is provided on the side of the conveying member facing away from the first clamping member, and the positioning plate is slidably connected to the stamping frame along a direction approaching or away from the conveying member. The stamping frame is provided with a positioning cylinder for driving the positioning plate to move. The positioning plate is slidably connected to a positioning block along the axis direction of the positioning disk. A reset member is provided between the positioning block and the positioning plate. When relative displacement occurs between the positioning block and the positioning plate, the reset member drives the positioning block to reset. A positioning groove adapted to the needle is provided on the upper end of the positioning block. When the needle is located in the positioning groove, it is directly below the stamping block.

[0014] By adopting the above technical solution, when the needle is positioned by the first clamping member, the positioning plate is pushed close to the needle by the positioning cylinder, and the positioning plate moves to drive the positioning block to move, so that the tip of the needle enters the positioning groove and fits with the inner wall of the positioning groove. At this time, the reset member is deformed, and the positioning block is positioned to position and guide the needle so that one side edge of the needle is under the stamping block. After the positioning is completed, the needle is clamped and positioned by the first clamping member, and the needle is positioned in advance, which is beneficial to improve the positioning accuracy of the needle.

[0015] Optionally, the adjusting member includes a driving block, a mounting block and a guide rail. A mounting frame is fixedly provided on the upper end of the stamping frame. The driving block is slidably connected to the mounting frame in the longitudinal direction. The mounting frame is provided with a longitudinal movement motor for driving the driving block to move. The mounting block is slidably connected to the driving block in the transverse direction and moves synchronously with the driving block. The stamping block is located at the lower end of the mounting block. A stamping cylinder is fixedly provided on the upper end of the mounting block. The stamping cylinder is used to drive the stamping block to move vertically. The guide rail is located at the upper end of the mounting block for guiding the mounting block to move along the length direction of the guide rail. The mounting frame is provided with a transverse movement member for driving the guide rail to translate or rotate laterally.

[0016] By adopting the above technical solution, the stamping frame supports the driving block through the mounting frame, and the longitudinal movement motor drives the driving block and the mounting block to move longitudinally when working. Under the connection action of the mounting block, the driving block drives the stamping block and the stamping cylinder to move synchronously when moving, thereby adjusting the position of the stamping block longitudinally. When the driving block drives the mounting block to move longitudinally, the guide rail guides the mounting block, and the position of the guide rail is adjusted by the transverse moving part, so that the guide rail drives the mounting block to shift laterally, thereby facilitating the lateral adjustment of the position of the stamping block. When the guide rail deviates from the moving direction of the driving block, the mounting block moves in the deflection direction of the guide rail, thereby facilitating the adjustment of the moving trajectory of the stamping block.

[0017] Optionally, the driving member includes a gear, a rack 1 and a rack 2, the gear is rotatably connected to the stamping frame, the rack 2 and the rack 1 are both slidably connected to the stamping frame along the length direction, the gear is located between the rack 1 and the rack 2, and is meshed with the rack 1 and the rack 2, the rod support member is located at the upper end of the rack 2, and is slidably connected to the rack 2 along the vertical direction, an elastic member is provided between the rod support member and the rack 2, the elastic member is used to push the rod support member close to the stamping block, a pull-back member is provided between the rack 2 and the stamping frame, the pull-back member is used to drive the rack 2 away from the stamping block, a resistance block is fixedly provided at the upper end of the rack 1, the stamping block is fixedly provided with a pressing block opposite to the resistance block, and the stamping frame is provided with a positioning mechanism, and when the rod support member conflicts with the needle, the positioning mechanism limits the vertical displacement of the rod support member.

[0018] By adopting the above technical solution, in the initial state, the shaft support and the punching block are far away from each other. When the punching block descends, it drives the pressing block close to the abutment block. When the pressing block contacts the abutment block, it drives the rack to move down through the abutment block. Under the connection of the gear, the second rack moves down and drives the second rack to rise. At this time, the pull-back member is deformed, and the second rack drives the shaft support to contact the needle through the elastic member. When the second rack continues to rise, the shaft support and the second rack are relatively displaced, and the elastic member is deformed and pushes the shaft support to fit the needle. At this time, the positioning mechanism supports and positions the needle, thereby limiting the vertical displacement of the shaft support, so that the shaft support supports the needle.

[0019] Optionally, the positioning mechanism includes a vertical moving plate, an upper limit plate, a lower limit plate, a guide block and a return spring. The vertical moving plate is located below the rod body support and is vertically slidably connected to the stamping frame. The stamping frame is provided with a driving rod for driving the vertical moving plate to move. The upper limit plate is horizontally fixed to the upper end of the vertical moving plate, and a baffle is fixed to the lower end of the rod body support. The baffle is located below the upper limit plate, and the lower limit plate is located on the side of the upper limit plate away from the clamping block and is horizontally slidably connected to the vertical moving plate. The gap between the upper limit plate and the lower limit plate is adapted to the vertical height of the baffle. The return spring is located between the vertical moving plate and the lower limit plate, and is used to drive the lower limit plate away from the baffle. The guide block is fixedly connected to the second rack and is below the baffle. When the guide block conflicts with the lower limit plate, the lower limit plate is pushed to move toward the baffle.

[0020] By adopting the above technical solution, before punching the needle, the vertical height of the vertical moving plate is adjusted by the driving rod. When the rod body support drives the baffle to contact the upper limit plate, the inclined surface fits the needle. At this time, the punching block is not in contact with the needle. The punching block continues to move, thereby driving the second rack and the rod body support to have relative displacement. When the second rack moves, it drives the guide block close to the lower limit plate. When the guide block contacts the lower limit plate, the lower limit plate is pushed to the bottom of the upper limit plate. At this time, the reset spring is deformed, and the upper limit plate and the lower limit plate cooperate to limit the vertical displacement of the baffle, thereby positioning the rod body support.

[0021] Optionally, the longitudinal connecting member includes a longitudinal moving rod and a movable plate, the movable plate is vertically fixedly connected to the side of the side edge support member facing away from the rod body support member, and the movable plate has a through opening along the length direction, the longitudinal moving rod is fixedly connected to the lower end of the stamping block, and the longitudinal moving rod passes through the through opening and fits against the inner wall of the through opening.

[0022] By adopting the above technical solution, the punching block drives the longitudinal shifting rod to move when moving in the longitudinal direction, so that the longitudinal shifting rod drives the moving plate to move through the through opening, and then drives the side edge support to move in the longitudinal direction through the moving plate.

[0023] In summary, the present application includes at least one of the following beneficial technical effects:

[0024] With the support of the punching frame, the needles are transported one by one to the first clamping member through the conveying member. The first clamping member clamps and positions the needles so that one side edge of the needles is directly below the punching block. The position of the punching block is adjusted in advance by the adjusting member according to the size of the needles so that the punching block is directly opposite to the side edge of the positioned needles. The punching block moves downward vertically, and the driving member drives the rod support member to rise until the inclined surface of the rod support member contacts the needle. At this time, the support plate fits the end surface of the needle away from the punching block, thereby supporting the needle, and the position of the support plate is adjusted in advance by the locking member according to the specifications of the needle, so that when the support plate supports the needle, the side edges of the needle to be processed are all located outside the rod support member. At this time, the side edge support member supports the side edges that need to be punched. During punching, the side edge support member avoids the punching block through the avoidance opening. When the punching block moves along the length direction of the needle, the side edge support member is driven to move synchronously through the longitudinal connecting member, thereby facilitating the punching of needles of different densities. When processing different side edges of the needle, the first clamping member and the needle are driven to rotate by the rotating member to move the unprocessed side edge to move below the punching block. During the stamping process of the needle, the shaft support supports and positions the entire needle, reducing the probability of the needle bending, and the side edge support supports the side edge of the needle that needs to be processed, thereby reducing the probability of the side edge of the needle being deformed during the stamping process, which is beneficial to improving the stamping processing quality of the needle;

[0025] In the initial state, the movable disk is in a position away from the positioning disk. At this time, the two clamping blocks are away from each other and distributed vertically. When the conveying member drives the needle to enter between the two clamping blocks, the pushing member drives the movable disk close to the positioning disk. When the movable disk moves, the two clamping blocks are driven close to each other through the two connecting rods. The two clamping blocks cooperate to clamp and position the needle. When the needle needs to be rotated, the positioning disk and the movable disk are driven to rotate through the rotating member, thereby driving the needle to rotate.

DETAILED DESCRIPTION

[0032] The present application is further described in detail below in conjunction with all the accompanying drawings.

[0033] The embodiment of the present application discloses an integrated sock machine sewing needle preparation device. Example

[0034] Reference Figure 1 and Figure 2 An integrated sock machine sewing needle preparation device includes a punching frame 1, a conveying member 2, a first clamping member 3, a punching block 4, a shaft support member 6 and a side edge support member 7. The conveying member 2 includes an upper conveyor belt 21 and a lower conveyor belt 22. The frame is provided with a support frame 12 for supporting the upper conveyor belt 21 and the lower conveyor belt 22. The support frame 12 is provided with two groups, and the two groups of support frames 12 are distributed vertically. The lower conveyor belt 22 is installed on the support frame 12 located below and is arranged horizontally. The upper conveyor belt 21 is located above the lower conveyor belt 22 and is parallel to the lower conveyor belt 22. The length of the upper conveyor belt 21 is less than the length of the lower conveyor belt 22. The gap between the upper conveyor belt 21 and the lower conveyor belt 22 constitutes a conveying channel for conveying needles.

[0035] Reference Figure 1 and Figure 2The upper conveyor belt 21 is connected to the support frame 12 located above, and the two support frames 12 are slidably connected to the punching frame 1 in the vertical direction. The punching part is provided with a second clamping member for driving the two support frames 12 to move closer to or away from each other. In this embodiment, the second clamping member is a combination of a bidirectional screw and a motor. Other structures can also be used, which are not limited here. The second clamping member is mainly used to adjust the distance between the upper conveyor belt 21 and the lower conveyor belt 22, so as to facilitate the adjustment of the width of the conveying channel, which is suitable for needles of different diameters. When processing the needles, the needles are placed on the lower conveyor belt 22, and the lower conveyor belt 22 drives the needles to move along the length direction of the punching frame 1 when working.

[0036] It should be noted that the needles described in this embodiment are standard triangular needles or gradient hook needles, the cross section of the needle leaf portion is an equilateral triangle, and the side edges of the needle leaf portion are parallel to each other.

[0037] Reference Figure 1 and Figure 2 The first clamping member 3 includes a positioning plate 31, a moving plate 32 and two groups of clamping blocks 33. The positioning plate 31 is located on one side of the conveying member 2 in the transverse direction and is rotatably connected to the punching frame 1. The axis of the positioning plate 31 is located between the upper conveyor belt 21 and the lower conveyor belt 22. When the conveying member 2 conveys the needle, the axis of the needle passes through the axis of the positioning plate 31. When the upper conveyor belt 21 and the lower conveyor belt 22 are driven to move by the support frame 12, the displacement of the upper conveyor belt 21 or the lower conveyor belt 22 relative to the axis of the positioning plate 31 is the same. The two clamping blocks 33 are both located on one side of the positioning plate 31 close to the lower conveyor belt 22, and are symmetrically arranged with the axis of the positioning plate 31 as the center.

[0038] Reference Figure 1 and Figure 2 The two clamping blocks 33 are both slidably connected to the positioning disk 31 along the diameter direction of the positioning disk 31. The moving disk 32 is located on the side of the positioning disk 31 away from the conveying member 2 and is coaxial with the positioning disk 31. Two slide bars 311 are fixedly provided on the side of the positioning disk 31 away from the conveying member 2. The slide bars 311 pass through the moving disk 32 and are slidably connected to the moving disk 32. Under the connection action of the slide bars 311, when the moving disk 32 rotates, the positioning disk 31 is driven to rotate. The stamping frame 1 is slidably connected to a pusher 13 along the axial direction of the positioning disk 31. The stamping frame 1 is provided with a pusher motor for driving the pusher 13 to move. The pusher 13 is rotatably connected to the moving disk 32. When the pusher 13 moves, the moving disk 32 is driven to move closer to or away from the positioning disk 31.

[0039] Reference Figure 1 and Figure 2A connecting rod 331 is hinged on one side of the clamping block 33 close to the positioning plate 31, and an end of the connecting rod 331 away from the clamping block 33 is hinged to the movable plate 32. The connecting rod 331 is inclined along the axis direction of the positioning plate 31. When the movable plate 32 approaches the positioning plate 31, the movable plate 32 drives the two clamping blocks 33 to approach each other through the connecting rod 331.

[0040] Reference Figure 1 and Figure 3 A positioning plate 9 is provided on the side of the stamping frame 1 away from the positioning disk 31. The positioning plate 9 is slidably connected to the stamping frame 1 along the axial direction of the positioning disk 31. The stamping frame 1 is provided with a positioning cylinder 92 for driving the positioning plate 9 to move. A positioning block 91 is slidably connected to the upper end of the positioning plate 9 along the axial direction of the positioning disk 31. The positioning block 91 is provided with a positioning groove 911 coaxial with the axis of the positioning disk 31. When the conveying member 2 drives the needle to move between the two clamping blocks 33, it stops. At this time, the positioning plate 9 is pushed close to the needle by the positioning cylinder 92. A reset member 912 is provided between the positioning block 91 and the positioning plate 9. The reset member 912 is a spring. One end of the spring is fixedly connected to the positioning block 91, and the other end is fixedly connected to the positioning plate 9. When the positioning plate 9 moves, the positioning block 91 is driven to move by the reset member 912.

[0041] Reference Figure 2 and Figure 3 When the positioning plate 9 moves, it drives the positioning block 91 close to the needle, and then makes the needle enter the positioning groove 911. The positioning groove 911 passes through the positioning block 91, and the end of the positioning groove 911 close to the conveying member 2 is circular, and the end away from the conveying member 2 is a regular triangle. The inner wall of the positioning groove 911 gradually changes along the axis direction of the positioning disk 31. When the needle enters the positioning groove 911, its side tip contacts the inner wall of the positioning groove 911 and moves with the inner wall of the positioning groove 911. At this time, the positioning block 91 pushes the needle to contact the positioning disk 31. At this time, the positioning plate 9 continues to move, so that the positioning block 91 and the positioning plate 9 are relatively displaced, and the reset member 912 is deformed.

[0042] Reference Figure 2 and Figure 3 , the positioning plate 9 continues to move, so that the positioning block 91 cooperates with the positioning plate 31 to squeeze the needle under the action of the reset member 912. When the tip of the needle passes through the end of the positioning groove 911 away from the conveying member 2, one side of its needle part is in a vertical state, and one side edge is in a horizontal state. At this time, the needle is in a state of waiting for processing. The push motor drives the push member 13 to approach the conveying member 2, so that the moving plate 32 drives the two clamping blocks 33 through the connecting rod 331 to cooperate to clamp and position the end of the needle away from the positioning block 91. After the clamping block 33 clamps the needle, the positioning cylinder 92 drives the positioning plate 9 and the positioning block 91 to reset.

[0043] Reference Figure 1 and Figure 2The punching frame 1 is equipped with a rotating member 11, which includes a rotating motor and a polygonal rod. The rotating motor is fixedly connected to the punching frame 1, and the polygonal rod is coaxially fixed with the output shaft of the rotating motor, and the polygonal rod is coaxial with the moving disk 32, and the polygonal rod passes through the moving disk 32 and is slidably connected with the moving disk 32. When the angle of the needle needs to be adjusted, the polygonal rod is driven to rotate by the rotating motor, so that the polygonal rod drives the moving disk 32 to rotate, and then the positioning disk 31 is driven to rotate by the sliding rod 311 to drive the needle to rotate.

[0044] Reference Figure 1 and Figure 4 The punching block 4 is located at the upper end of the punching frame 1. The punching frame 1 is provided with an adjusting member 5. The adjusting member 5 includes a driving block 51, a mounting block 52 and a guide rail 53. The upper end of the punching frame 1 is fixed with a mounting frame 14. The driving block 51 is slidably connected with the mounting frame 14 along the longitudinal direction. The longitudinal direction mentioned here is the length direction after the needle is clamped and positioned. The mounting frame 14 is equipped with a longitudinal movement motor for driving the driving block 51 to move. The mounting block 52 is slidably connected with the driving block 51 along the transverse direction. When the driving block 51 moves, the mounting block 52 is driven to move. The mounting frame 14 is provided with a transverse moving member 54. The transverse moving member 54 includes a moving block 1 541 and a moving block 2 542. Both the moving block 1 541 and the moving block 2 542 are slidably connected with the mounting frame 14 along the transverse direction. The driving block 51 is located between the moving block 1 541 and the moving block 2 542. The mounting frame 14 is provided with two moving rods, which are used to drive the moving block 1 541 and the moving block 2 542 to move along the transverse direction respectively.

[0045] Reference Figure 1 and Figure 4 The guide rail 53 is located at the upper ends of the moving block 1 541 and the moving block 2 542, and the guide rail 53 is rotatably connected to the moving block 1 541 in the horizontal direction. An adjustment groove is provided at one end of the guide rail 53 away from the moving block 1 541 along the length direction. A round rod is fixed at the upper end of the moving block 2 542. The round rod is located in the adjustment groove and fits with the inner wall of the adjustment groove. The guide rail 53 has a guide groove along its length direction. A guide wheel adapted to the guide groove is rotatably connected to the upper end of the mounting block 52. The guide wheel is located in the guide groove and is rollingly connected to the inner wall of the guide groove.

[0046] Reference Figure 1 and Figure 4The punching block 4 is located at the lower end of the mounting block 52. The mounting block 52 is equipped with a punching cylinder 521. The output end of the punching cylinder 521 passes through the mounting block 52 and is fixedly connected to the punching block 4. When the mounting block 52 moves, it drives the punching block 4 and the punching cylinder 521 to move. When the punching cylinder 521 works, it drives the punching block 4 to move back and forth vertically. In the initial state, the lower end of the punching block 4 is directly opposite to the horizontal side edge of the needle blade. At this time, the guide rail 53 is arranged in the longitudinal direction. When the longitudinal motor drives the driving block 51 to move in the longitudinal direction, the punching block 4 moves in the length direction of the needle, thereby adjusting the punching position of the punching block 4. At this time, it is suitable for processing needles with uniform teeth. When processing needles of different specifications, by moving the moving block 1 541 and the moving block 2 542 in the same direction, the guide block 164 drives the mounting block 52 to translate in the horizontal direction, thereby adjusting the position of the punching block 4 in the horizontal direction.

[0047] Reference Figure 1 and Figure 4 When processing a gradient tooth needle with different tooth sizes, the moving block 1 541 and the moving block 2 542 are moved in different directions, so that the guide rail 53 is deflected along the axis direction of the positioning plate 31, and the deflection angle is adapted to the gradient angle of the needle teeth. When the driving block 51 moves in the longitudinal direction, the guide rail 53 guides the mounting block 52, so that the stamping block 4 gradually approaches or moves away from the axis of the needle when stamping different teeth.

[0048] Reference Figure 1 and Figure 4 The rod support member 6 is located below the stamping block 4, and the stamping frame 1 is provided with a driving member 15 for driving the rod support member 6 to move. The driving member 15 includes a rack 152, a rack 2 153 and a gear 151. The rack 2 153 is located below the rod support member 6 and is slidably connected to the stamping frame 1 along the vertical direction. The rod support member 6 is slidably connected to the rack 2 153 along the vertical direction, and an elastic member 154 is provided between the rod support member 6 and the rack 2 153. The elastic member 154 is a spring, one end of the spring is fixedly connected to the rod support member 6, and the other end is fixedly connected to the rack 2 153. When the rack 2 153 moves, the rod support member 6 is driven to move through the elastic member 154.

[0049] Reference Figure 1 and Figure 4The gear 151 is rotatably connected to the punching frame 1 and meshes with the second rack 153. When the gear 151 rotates, it drives the second rack 153 to move vertically. The first rack 152 is located on the side of the gear 151 away from the second rack 153 and is also meshed with the gear 151. When the first rack 152 descends vertically, the second rack 153 is driven to move upward through the gear 151. A pressing block 41 is fixedly provided on one side of the punching block 4. When the punching block 4 moves, it drives the pressing block 41 to move. A resisting block 156 adapted to the pressing block 41 is fixedly provided on the upper end of the rack 152. When the punching block 4 approaches the needle, it drives the pressing block 41 to approach the resisting block 156.

[0050] Reference Figure 4 and Figure 5 , the upper end of the shaft support 6 is provided with an inclined surface 60. When the needle is positioned, the lower end surface of its needle blade is parallel to the inclined surface 60. A pull-back member 155 is provided between the rack 2 153 and the punching frame 1. The pull-back member 155 is also a spring. In the natural state, the pull-back member 155 drives the rack 2 153 away from the punching block 4. When punching the needle, the punching block 4 is close to the needle. At this time, the pressing block 41 first contacts the abutment block 156, and then drives the rack 1 152 to descend through the abutment block 156. Under the connection of the gear 151, the rack 1 152 descends and drives the rack 2 153 to drive the shaft support 6 to rise until the inclined surface 60 of the shaft support 6 abuts against the lower end surface of the needle blade.

[0051] Reference Figure 4 and Figure 5 A support plate 61 is provided at the upper end of the shaft support 6, and the support plate 61 is slidably connected to the shaft support 6 along the longitudinal direction. The shaft support 6 is provided with a locking piece 611, and the locking piece 611 is a screw rod, which passes through the support plate 61 and is threadedly connected to the support plate 61. The position of the support plate 61 can be adjusted by rotating the screw rod. When the inclined surface 60 contacts the lower end surface of the needle blade of the thorn, the support plate 61 fits with the vertical side surface of the needle blade. At this time, the support plate 61 cooperates with the needle support member to support the shaft of the thorn.

[0052] Reference Figure 4 and Figure 5 The side edge support member 7 is located on the side of the shaft support member 6 close to the stamping part, and the side edge support member 7 is slidably connected with the shaft support member 6 in the horizontal direction, and drives the side edge support member 7 to move when the shaft support member 6 moves vertically. The side edge support member 7 is provided with an escape opening 71 in the vertical direction, and the escape opening 71 is located directly below the stamping block 4 and directly opposite to the stamping block 4. The upper end surface of the side edge support member 7 is flush with the inclined surface 60. Before processing the needle, the position of the support plate 61 is pre-adjusted so that when the support plate 61 cooperates with the shaft support member 6 to support the shaft of the needle, the upper end of the side edge support member 7 is in contact with the side edge of the needle that needs to be stamped.

[0053] Reference Figure 4 and Figure 5 The punching frame 1 is provided with a positioning mechanism, which includes a vertical moving plate 161, an upper limit plate 162, a lower limit plate 163, a guide block 164 and a return spring 165. The vertical moving plate 161 is slidably connected to the punching frame 1 in the vertical direction. The punching frame 1 is provided with a driving rod 17 for driving the vertical moving block to move vertically. The vertical position of the vertical moving plate 161 can be adjusted by the driving rod 17. The upper limit plate 162 is horizontally fixed to the upper end of the vertical moving plate 161. The lower end of the rod support 6 is fixedly connected to a baffle 62. The baffle 62 is located directly below the upper limit plate 162. When the inclined surface 60 contacts the needle body of the needle, the upper end surface of the baffle 62 contacts the lower end surface of the upper limit plate 162.

[0054] Reference Figure 4 and Figure 5 The lower limit plate 163 is slidably connected with the vertical moving plate 161 in the horizontal direction. When the vertical moving plate 161 moves, the lower limit plate 163 is driven to move, and the distance between the upper end surface of the upper limit plate 162 and the lower end surface of the lower limit plate 163 is adapted to the thickness of the baffle 62 in the vertical direction. The return spring 165 is a spring, one end of which is fixedly connected to the lower limit plate 163, and the other end is fixedly connected to the vertical moving plate 161. In the natural state of the return spring 165, the lower limit plate 163 is at a position away from the baffle 62. When the baffle 62 approaches the lower limit plate 163, the baffle 62 avoids the lower limit plate 163.

[0055] Reference Figure 4 and Figure 5 The guide block 164 is fixedly connected to the second rack 153. When the second rack 153 moves, it drives the guide block 164 to move. The baffle 62 is located between the guide block 164 and the upper limit plate 162. When the shaft support 6 contacts the needle of the needle, the punch block 4 has not yet contacted the needle. The punch block 4 continues to press down, so that the second rack 153 continues to move up, and the elastic member 154 gradually deforms. When the second rack 153 moves, it drives the guide block 164 to approach the lower limit plate 163. The upper end of the guide block 164 is inclined. When the guide block 164 contacts the lower limit plate 163, it pushes the lower limit plate 163 to move to the lower end of the baffle 62, and the return spring 165 is deformed at this time.

[0056] Reference Figure 4 and Figure 5The upper limit plate 162 and the lower limit plate 163 cooperate to limit the vertical displacement of the baffle 62, thereby limiting the vertical displacement of the shaft support 6 and the side edge support 7, which is beneficial to improving the support stability of the needle. After the punching block 4 contacts the needle blade of the needle, it punches the needle, and the punched waste falls off along the avoidance opening 71. The shaft support 6 is equipped with a carrying box for placing waste. A longitudinal connecting member 8 is provided between the punching block 4 and the side edge support 7. The longitudinal connecting member 8 includes a longitudinal moving rod 81 and a moving plate 82. The longitudinal moving rod 81 is arranged vertically, and the longitudinal moving rod 81 is fixedly connected to the lower end of the punching block 4. When the punching block 4 moves, it drives the longitudinal moving rod 81 to move. The moving plate 82 is fixedly connected to the side edge support 7. When the moving plate 82 moves, it drives the side edge support 7 to move.

[0057] Reference Figure 4 and Figure 5 The movable plate 82 has a through hole 821 opened in the transverse direction, and the longitudinal rod 81 passes through the through hole 821 and fits against the inner wall of the through hole 821. When the stamping block 4 moves in the transverse direction, the longitudinal rod 81 moves along the through hole 821. At this time, the side edge support 7 is stationary. When the stamping block 4 moves in the longitudinal direction, the longitudinal rod 81 drives the side edge support 7 to move in the longitudinal direction through the movable plate 82, thereby adjusting the position of the side edge support 7 in the longitudinal direction, so as to facilitate the stamping of teeth in different positions.

[0058] Reference Figure 1 and Figure 4 When punching the teeth on the same side edge, the punching block 4 moves up slightly while moving back and forth vertically, so that the shaft support 6 can keep supporting the needle. After punching one side edge, the punching block 4 moves up significantly, so that the second rack 153 drives the guide block 164 to separate from the lower limit plate 163, and the lower limit plate 163 separates from the block under the action of the return spring 165, so that the second rack 153 drives the shaft support 6 to separate from the needle. The needle is driven to rotate 120 degrees by the rotating member 11. When the other side edge is in a horizontal state, the punching block 4 moves down again, and then punches the side edge in a horizontal state.

[0059] The working principle of the integrated sock machine sewing needle preparation device of the embodiment of the present application is as follows: when the needle is stamped by the stamping block 4, the shaft support member 6 and the support plate 61 cooperate to support the part outside the stamping processing range of the needle blade part of the needle. At the same time, the side edge support member 7 supports the side edge of the needle blade that needs to be stamped, and the blank after stamping falls into the carrier box along the avoidance opening 71. Through the connection between the gear 151, the rack 1 152 and the rack 2 153, the punching block 4 drives the shaft support 6 and the side edge support 7 to move synchronously when moving vertically, which is beneficial to improving the convenience of punching the needle. When the punching block 4 moves longitudinally and punches teeth at different positions, the side edge support 7 moves synchronously with the punching block 4 under the linkage action of the longitudinal connecting member 8, so that the avoidance opening 71 always remains opposite to the punching block 4. In the process of punching the needle by the punching block 4, the punching position and the unprocessed position of the needle blade are both supported, which is beneficial to reducing the probability of deformation of the side edge of the needle during the punching process and improving the punching processing quality of the needle.

[0060] 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.
