Abstract
Description
Technical Field
[0001] This application relates to the field of automatic sock knitting machines, and more particularly to a fully automatic sock knitting machine suitable for stockings. Background Technology
[0002] Currently, the most advanced sock knitting machines on the market typically adopt an integrated structure for knitting, turning, and sewing, allowing for the combined assembly of various equipment to achieve automated sock production. First, the knitting unit weaves raw materials into tubular sock tubes. Then, a pick-up component on the machine transfers the knitted tubes to the turning unit, where negative pressure draws them into the turning tube. A turning lifting cylinder extends from inside the turning tube to turn the tube inside out. Finally, the sewing component sews the socks together to obtain a complete sock.
[0003] This type of sock machine is generally suitable for producing shorter socks, but it presents significant problems for long socks, especially those exceeding the pick-up stroke of the pick-up component (typically 50cm). When long socks are transferred from the knitting unit to the turning unit, the ends of the socks cannot be completely removed from the knitting unit and are difficult to be sucked into the turning tube, causing the sock machine to stop production and affecting production efficiency. Summary of the Invention
[0004] In order to adapt automatic sock knitting machines to the production of long socks, this application provides a fully automatic sock knitting machine suitable for long socks.
[0005] The fully automatic sock knitting machine suitable for long stockings provided in this application adopts the following technical solution:
[0006] An automatic sock knitting machine suitable for stockings includes a knitting machine housing, a knitting device, a sewing device, a pickup device, and a sock-turning device. An upper support base and a lower support base are fixed to the same vertical end face of the knitting machine housing. The upper support base is located above the lower support base and away from the operator. The knitting device is disposed on the upper end face of the knitting machine housing. The sewing device and the pickup device are disposed on the upper end face of the upper support base. The sewing device is located on the side of the pickup device away from the knitting device. The sock-turning device includes a sock-turning outer... The device includes a sock-turning tube and a vertically telescopic sock-turning tube mounted on the outer sock-turning tube; the outer sock-turning tube is horizontally movable on the upper end face of the lower support base; the outer sock-turning tube moves between the rotational central axes of the sock-knitting device and the sock-sewing device; the sock-turning device also includes a horizontal moving mechanism for driving the outer sock-turning tube to move horizontally; a sock blank lifting device is provided between the outer sock-turning tube and the sock-knitting machine housing; the sock blank lifting device is used to drive the sock blank between the sock-turning tube and the sock-knitting device to rise, thereby leaving the sock-knitting device and approaching the sock-turning tube.
[0007] By adopting the above technical solution, after the sock knitting device knits the sock blank, the picking device grabs the upper end of the sock blank and brings it to the sock sewing device. Then, the horizontal moving mechanism drives the sock turning cylinder to move towards the sock knitting machine box. Next, the sock turning cylinder rises and sucks up the middle of the sock blank. Then, the sock blank lifting device drives the sock blank between the sock turning cylinder and the sock knitting device to rise, so that the end of the sock blank leaves the sock knitting device and approaches the sock turning cylinder. Then, the sock turning cylinder descends, and at the same time, the sock blank lifting device drives the sock blank to descend. During this process, the inside of the sock blank is sucked into the sock turning cylinder, which facilitates subsequent sock turning. This is suitable for the production of long socks.
[0008] Optionally, the sock blank lifting device includes a first sock blank lifting seat and a first sock blank lifting component that are vertically movable; the first sock blank lifting component is fixed to the end face of the sock knitting machine box near the outer cylinder of the sock turning and is used to drive the first sock blank lifting seat to move vertically.
[0009] By adopting the above technical solution, the first sock blank lifting seat is driven to rise, so that the middle part of the sock blank between the sock turning tube and the sock knitting device moves upward. As the sock turning tube sucks the sock blank, the end of the sock blank leaves the sock knitting device and approaches the sock turning tube as the first sock blank lifting seat rises. Then the suction force of the sock turning tube can suck the sock blank into the sock turning tube, which facilitates subsequent sock turning and is suitable for the production of long socks.
[0010] Optionally, the first sock blank lifting seat includes a lifting seat body and a pair of cylindrical stop bars disposed at the upper end of the lifting seat body; the pair of stop bars are located on both sides of the sock blank.
[0011] By adopting the above technical solution, the presence of a pair of stop levers can prevent the sock blank from accidentally falling off the lifting seat body, which is conducive to the sock blank being sucked into the sock turning tube.
[0012] Optionally, the levers are inclined and the lower ends of a pair of levers are close to each other, while the upper ends are far apart.
[0013] By adopting the above technical solution, the opening between the pair of levers is larger, which is more conducive to the sock blank entering the lifting seat body.
[0014] Optionally, the upper end of the lifting seat body is formed with a pair of connecting threaded holes; the stop bar corresponds one-to-one with the connecting threaded holes and the lower end of the stop bar is screwed into the connecting threaded hole on the corresponding side.
[0015] By adopting the above technical solution, the stop lever is easy to disassemble and assemble, which is beneficial for subsequent replacement and maintenance.
[0016] Optionally, the upper end of the lifting seat body is formed into a semi-cylindrical surface.
[0017] By adopting the above technical solution, the upper end of the lifting seat body is formed into a semi-cylindrical surface, which effectively avoids the sock blank being scratched.
[0018] Optionally, the first sock blank lifting seat further includes a pair of movable rings sleeved and slidably disposed on the lifting seat body and an adjustment component for driving the pair of movable rings to move away from or closer to each other; the stop bar corresponds one-to-one with the movable rings and the stop bar is fixed to the upper end of the movable ring on the corresponding side.
[0019] By adopting the above technical solution, when the first sock blank lifting seat is at the lowest point, the pair of stops are furthest apart, which is conducive to the sock blank entering between the pair of stops. When the first sock blank lifting seat is at the highest point, the pair of stops move closer to each other until they are closest, thus restricting the sock blank and facilitating the subsequent sucking of the sock blank into the sock turning tube.
[0020] Optionally, a pair of auxiliary support plates are formed at one end of the lifting seat body near the outer sleeve of the sock; a pair of horizontally distributed cylindrical auxiliary support rods are formed between the end faces of the pair of auxiliary support plates that are close to each other; a gap is provided between the pair of auxiliary support rods; and a gap is provided between the lifting seat body and the auxiliary support rods close to it.
[0021] By adopting the above technical solution, the presence of a pair of auxiliary support rods prevents the end of the sock blank from leaving the first sock blank lifting seat too quickly and falling to the lower side of the upper end of the sock turning tube. This facilitates the sock blank being sucked into the sock turning tube more smoothly.
[0022] Optionally, the sock blank lifting device includes a cylindrical first lifting rod and an inclined lifting component fixed to the end face of the sock knitting machine box near the operator; the first lifting rod is inclined and movable between the sock outer cylinder and the sock knitting machine box; the inclined lifting component is used to drive the first lifting rod to move inclined; when the first lifting rod moves away from the sock knitting machine box, the first lifting rod rises; when the first lifting rod moves closer to the sock knitting machine box, the first lifting rod falls.
[0023] By adopting the above technical solution, the tilting lifting component drives the first lifting rod to tilt upward, which accelerates the sock blank from leaving the sock knitting device and approaching the sock turning tube, which is conducive to the sock blank being sucked into the sock turning tube.
[0024] Optionally, the sock blank lifting device includes a rotating central column rotatably connected to the end face of the lower support seat near the operator, a rotating drive mechanism for driving the rotating central column to rotate, a rotating support seat fixed on the rotating central column, a radial lifting member fixed on the rotating support seat, and a cylindrical second lifting rod connected to the radial lifting member; the radial lifting member is used to drive the second lifting rod to move radially along the rotating central column.
[0025] By adopting the above technical solution, the radial lifting component drives the second lifting rod to tilt upward, so that the sock blank leaves the sock knitting device. Then, the rotation drive mechanism drives the rotation center column to rotate, so that the rotation support, radial lifting component and second lifting rod together turn towards the sock turning tube, thereby getting closer to the sock turning tube, which is conducive to the sock blank being sucked into the sock turning tube.
[0026] In summary, the beneficial effects of this application are as follows:
[0027] 1. It facilitates the removal of the sock blank from the knitting device and its intake into the sock-turning cylinder, making subsequent sock turning easier and thus suitable for the production of long socks.
[0028] 2. Avoid scratching the raw sock. Attached Figure Description

[0047] The following is in conjunction with the appendix Figure 1-9 This application will be described in further detail.
[0048] Example 1 discloses a fully automatic sock knitting machine suitable for stockings, referencing... Figure 1 The machine includes a sock knitting machine housing 10, a sock knitting device 40, a sock sewing device 50, a pick-up device 60, and a sock turning device 70. An upper support 20 and a lower support 30 are fixed to the same vertical end face of the sock knitting machine housing 10. The upper support 20 is located above the lower support 30 and away from the operator. The sock knitting device 40 is disposed on the upper end face of the sock knitting machine housing 10. The sock sewing device 50 and the pick-up device 60 are disposed on the upper end face of the upper support 20. The sock sewing device 50 is located on the side of the pick-up device 60 away from the sock knitting device 40. The sock turning device 70 includes a sock turning outer tube 7. 1. A sock-turning tube 72 is vertically telescopically mounted on the sock-turning outer tube 71; the sock-turning outer tube 71 is horizontally movably mounted on the upper end face of the lower support 30; the sock-turning outer tube 71 moves between the rotational central axes of the sock-knitting device 40 and the sock-sewing device 50; the sock-turning device 70 also includes a horizontal moving mechanism 73 for driving the sock-turning outer tube 71 to move horizontally; a sock blank lifting device 80 is provided between the sock-turning outer tube 71 and the sock-knitting machine housing 10; the sock blank lifting device 80 is used to drive the sock blank between the sock-turning tube 72 and the sock-knitting device 40 away from the sock-knitting device 40 and closer to the sock-turning tube 72.
[0049] The sock knitting device 40, sock sewing device 50, picking device 60, and sock turning device 70 are all existing structures and will not be described in detail.
[0050] refer to Figure 1 A vertical support plate 31 is formed on the upper end of the lower support base 30 away from the end of the sock knitting machine box 10; the horizontal moving mechanism 73 includes a motor and a ball screw; the ball screw is disposed between the vertical support plate 31 and the sock knitting machine box 10.
[0051] refer to Figures 1-3 The sock blank lifting device 80 includes a first sock blank lifting seat 82 and a first sock blank lifting component 81, which are vertically movable. The first sock blank lifting component 81 is fixed on the end face of the sock machine box 10 near the outer sock cylinder 71 and is used to drive the first sock blank lifting seat 82 to move vertically.
[0052] refer to Figures 1-3 The first sock blank lifting component 81 includes a first sock blank lifting cylinder; the first sock blank lifting cylinder has a pair of piston rods distributed along the length direction of the first sock blank lifting seat 82; the first sock blank lifting seat 82 is fixed to the upper ends of the pair of piston rods of the first sock blank lifting cylinder.
[0053] refer to Figure 3 The first sock blank lifting seat 82 includes a lifting seat body 821 and a pair of cylindrical stop bars 822 disposed on the upper end of the lifting seat body 821; the pair of stop bars 822 are located on both sides of the sock blank; in order to facilitate the disassembly and assembly of the stop bars 822, the lower end of the stop bar 822 is formed with external threads, and the upper end of the lifting seat body 821 is formed with a pair of connecting threaded holes that mate with the lower end of the stop bars 822; the upper end of the lifting seat body 821 is formed with a semi-cylindrical surface, which reduces the friction between the sock blank and the lifting seat body 821 and reduces damage to the sock blank; the end of the stop bar 822 away from the lifting seat body 821 is formed with a hemispherical shape, which reduces the possibility of scratching the sock blank.
[0054] refer to Figure 3 and Figure 4 A pair of stop levers 822 can be set vertically or tilted at the same time. When the pair of stop levers 822 are tilted, the lower ends of the pair of stop levers 822 are close to each other and the upper ends are far apart. The tilted pair of stop levers 822 increases the opening between the upper ends, making it easier for the sock blank to enter between the pair of stop levers 822.
[0055] To prevent the stocking blank from detaching from the lifting seat body 821 too quickly, causing the end of the stocking blank to fall below the upper opening of the sock sleeve 72, refer to... Figure 5A pair of auxiliary support plates 8211 are formed at one end of the lifting seat body 821 near the outer sleeve 71; a pair of horizontally distributed cylindrical auxiliary support rods 826 are formed between the end faces of the pair of auxiliary support plates 8211 that are close to each other; a gap is provided between the pair of auxiliary support rods 826; a gap is provided between the lifting seat body 821 and the auxiliary support rods 826 that are close to it; a damping layer 8261 is sleeved on the cylindrical surface of the auxiliary support rods 826.
[0056] The working principle of a fully automatic sock knitting machine suitable for long stockings in Example 1 is as follows:
[0057] The sock knitting device 40 completes the knitting of the sock blank, and then the picking device 60 grabs the upper end of the sock blank and moves it to the sewing device 50. Since the sock is long, the other end of the sock blank is still at the knitting device 40. At this time, the horizontal moving mechanism 73 moves the sock turning outer cylinder 71 closer to the sock knitting machine box 10, and then the sock turning cylinder 72 rises to suck up the sock blank. Then, the first sock blank lifting cylinder drives the first sock blank lifting seat 82 to rise. In this way, the lifting seat body 821 drives the sock blank to rise. During this process, the end of the sock blank located at the knitting device 40 leaves the knitting device 40. Then, the sock turning cylinder 72 begins to suck the sock blank inward. At the same time, the first sock blank lifting cylinder drives the first sock blank lifting seat 82 to descend. In this way, the end of the sock blank away from the sewing device 50 is completely sucked into the sock turning cylinder 72.
[0058] Example 2: The difference between Example 2 and Example 1 is as follows: (Refer to...) Figure 6 and Figure 7 A pair of levers 822 are not directly connected to the lifting seat body 821; the first sock blank lifting seat 82 also includes a pair of moving rings 823 sleeved and slidably disposed on the lifting seat body 821 and an adjustment component for driving the pair of moving rings 823 to move away from or closer to each other; the levers 822 and the moving rings 823 correspond one-to-one and the levers 822 are fixed to the upper end of the moving rings 823 on the corresponding side.
[0059] refer to Figure 6 and Figure 7The lower end face of the lifting seat body 821 is formed with a pair of movable grooves 8210 distributed along its length direction; the lower part of the movable ring 823 is formed with a sliding block 8231 that cooperates with the movable grooves 8210; the adjustment assembly includes an adjustment motor 824 and an adjustment threaded rod 825; the axial direction of the adjustment threaded rod 825 is parallel to the length direction of the lifting seat body 821 and is rotatably connected to the lifting seat body 821; the adjustment threaded rod 825 passes through a pair of movable grooves 8210; the portions of the adjustment threaded rod 825 located in the pair of movable grooves 8210 are respectively formed with external threads and these external threads rotate in opposite directions; a pair of sliding blocks 8231 are respectively screwed to different external threads of the adjustment threaded rod 825; the adjustment motor 824 is fixed on the end face of the lifting seat body 821 away from the upper support seat 20 and the adjustment threaded rod 825 is coaxially connected to the output shaft of the adjustment motor 824.
[0060] The working principle of Embodiment 2: Before the first sock blank lifting seat 82 rises, the pair of moving rings 823 are farthest apart. Then, when the first sock blank lifting seat 82 rises to the highest point, the adjusting motor 824 drives the adjusting threaded rod 825 to rotate, thereby driving the pair of sliding blocks 8231 to move closer along the pair of moving slide grooves 8210. That is, the pair of moving rings 823 move closer to each other, and the pair of stop rods 822 also move closer to each other. In this way, the pair of stop rods 822 can restrict the sock blank to the corresponding position.
[0061] Example 3: The difference between Example 3 and Example 1 is as follows: (Refer to...) Figure 8 The sock blank lifting device 80 includes a cylindrical first lifting rod 84 and an inclined lifting component 83 fixed on the end face of the sock knitting machine box 10 near the operator; the first lifting rod 84 is inclined and movable between the sock outer cylinder 71 and the sock knitting machine box 10; the inclined lifting component 83 is used to drive the first lifting rod 84 to move inclined; when the first lifting rod 84 moves away from the sock knitting machine box 10, the first lifting rod 84 rises; when the first lifting rod 84 moves closer to the sock knitting machine box 10, the first lifting rod 84 falls.
[0062] refer to Figure 8 The hosiery machine housing 10 has an inclined fixed mounting plate 11 formed on the end face near the operator; the end of the fixed mounting plate 11 near the outer sock tube 71 is lower than the end away from the outer sock tube 71; the inclined lifting component 83 includes an inclined lifting cylinder; the inclined lifting cylinder is vertically fixed on the end face of the fixed mounting plate 11 near the outer sock tube 71; a first lifting support plate 831 is fixed on the piston rod of the inclined lifting cylinder; a first lifting rod 84 is horizontally fixed on the end face of the first lifting support plate 831 near the hosiery machine housing 10.
[0063] The working principle of a fully automatic sock knitting machine suitable for long stockings in Example 3 is as follows:
[0064] The sock knitting device 40 completes the knitting of the sock blank, and then the picking device 60 grabs the upper end of the sock blank and moves it to the sock sewing device 50. Since the length of the sock is large, the other end of the sock blank is still at the sock knitting device 40. At this time, the horizontal moving mechanism 73 moves the sock turning outer cylinder 71 closer to the sock knitting machine box 10, and then the sock turning cylinder 72 rises to suck up the sock blank. Then, the tilting lifting cylinder drives the first lifting rod 84 to rise. In this way, the first lifting rod 84 makes the end of the sock blank leave the sock knitting device 40 and approach the sock turning cylinder 72. Then the sock turning cylinder 72 begins to suck the sock blank inward.
[0065] Example 4: The difference between Example 4 and Example 1 is as follows: (Refer to...) Figure 9 The sock blank lifting device 80 includes a rotating central column 87 rotatably connected to the end face of the lower support 30 near the operator, a rotating drive mechanism for driving the rotating central column 87 to rotate, a rotating support 871 fixed on the rotating central column 87, a radial lifting member 88 fixed on the rotating support 871, and a cylindrical second lifting rod 89 connected to the radial lifting member 88; the radial lifting member 88 is used to drive the second lifting rod 89 to move radially along the rotating central column 87.
[0066] refer to Figure 9 The lower support base 30 has a lower vertical support plate 32 and a horizontal guide bar 33 formed on the end face near the operator. The horizontal guide bar 33 is located on the lower side of the rotation center column 87. The rotation drive mechanism includes a rotation drive cylinder 85 horizontally fixed on the vertical end face of the lower vertical support plate 32 near the rotation center column 87, a rotation drive rack 86 fixed on the piston rod of the rotation drive cylinder 85, and a rotation drive gear 872 coaxially fixed on the rotation center column 87. The rotation drive rack 86 is slidably disposed on the horizontal guide bar 33 and meshes with the upper rotation drive gear 872.
[0067] refer to Figure 9 The radial lifting component 88 includes a radial lifting cylinder fixed on the rotating support seat 871; a radial lifting support plate 881 is fixed on the piston rod of the radial lifting cylinder; and a second lifting rod 89 is horizontally fixed on the end face of the radial lifting support plate 881 near the lower support seat 30.
[0068] The working principle of a fully automatic sock knitting machine suitable for long stockings in Example 4 is as follows:
[0069] The sock knitting device 40 completes the knitting of the sock blank, and then the picking device 60 grabs the upper end of the sock blank and moves it to the sewing device 50. Since the length of the sock is large, the other end of the sock blank is still at the knitting device 40. The horizontal moving mechanism 73 moves the sock-turning outer cylinder 71 closer to the sock knitting machine box 10, and then the sock-turning cylinder 72 rises to suck up the sock blank. Then, the radial lifting cylinder drives the second lifting rod 89 to rise. During this process, the second lifting rod 89 moves closer to the knitting device 40, so that the end of the sock blank located at the sewing device 50 leaves the knitting device 40. Then, the rotating drive cylinder 85 drives the rotating drive rack 86 to move horizontally towards the side of the sock knitting machine box 10. Through the rack and pinion transmission, the rotating center column 87 rotates, thereby driving the radial lifting cylinder to swing and move closer to the sock-turning cylinder 72. In this way, the sock blank moves closer to the sock-turning cylinder 72, and then the sock-turning cylinder 72 begins to suck the sock blank inward.
[0070] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
