Description

Technical Field

[0001] The utility model relates to the technical field of textile machinery accessories, in particular to a Uster seat with a yarn clamping device on a computerized flat knitting machine. Background Technique

[0002] When the current flat knitting machine starts the knitting action, the overhead bridge will move horizontally back and forth on the needle bed base to knit the yarn. The Uster seat is located on several parallel crossbars of the overhead bridge, which is convenient for cooperating with the movement of the overhead bridge to carry out yarn hooking and knitting. During the operation of the overhead bridge, in order to achieve the purpose of knitting different patterns, multiple Uster seats will be set. The multiple Uster seats are respectively located on the side and the middle of the crossbar. During the back-and-forth movement of the overhead bridge, there will be a period of time when the Uster seat close to the side of the crossbar is idle. After running for a period of time, the state will be switched so that another Uster seat close to the middle position of the crossbar is idle. However, there will be a problem with the idle Uster seat. Since the yarn hooking part at the bottom of the Uster seat will continuously hook the yarn, when the knitted fabric descends with the roller after the yarn is knitted, the idle Uster seat will also continuously hook the yarn, and the yarn will descend accordingly, resulting in waste of yarn. When the Uster seat fails or the yarn is changed, the employee needs to always hold the sliding part with one hand and thread and connect the yarn with the other hand. The inconvenient operation leads to low efficiency. At the same time, the traditional Uster seat cannot adjust the reciprocating movement stroke of the driving sliding part of the overhead bridge of the flat knitting machine, and can only adjust the garment styles of the flat knitting machine by replacing other models of Uster seats. Therefore, we propose a Uster seat with a yarn clamping device on a computerized flat knitting machine. Content of the Utility Model

DETAILED DESCRIPTION

[0025] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0026] Embodiment 1, as Figures 1-4 shown, the present utility model provides a technical solution: a Uster seat with a yarn clamping device on a computerized flat knitting machine, including a base 9, a sliding member 10, two yarn clamps 1 distributed on both sides of the base 9, and an elastic reset member for driving the elastic reset of the sliding member 10;

[0027] The elastic reset member includes folded pieces A4 and folded pieces B7 installed at both ends of one side surface of the base 9. Reset springs A5 and reset springs B6 are respectively hung in the middle of the folded pieces A4 and folded pieces B7. The elastic reset member further includes a spring hanging rod 8 fixed in the middle of the sliding member 10 and used for hanging the reset springs A5 and reset springs B6. Horizontal stop pieces 401 are fixedly arranged at the tops of the folded pieces A4 and folded pieces B7;

[0028] The sliding member 10 is slidably installed on one side surface of the base 9. A limiting rod structure 3 for temporarily restricting the movement of the folded piece A4 is elastically arranged on one side of the top of the sliding member 10. The limiting rod structure 3 includes a sleeve 303 fixed on the other side surface of the sliding member 10. A limiting rod 301 is embedded in the sleeve 303, and a limiting spring 302 is sleeved in the middle of the limiting rod 301;

[0029] Two adjusting grooves 1001 are symmetrically opened on the left and right about the vertical center line at the top end of the sliding member 10. Two sheep's head bolts 201 are embedded in the adjusting grooves 1001, and both of the two sheep's head bolts 201 are threadedly connected to an independent sheep's head block 2;

[0030] Two track grooves 1002 are symmetrically opened on the left and right about the vertical center line in the middle of the sliding member 10. The yarn clamp 1 includes a housing A101 and a housing B107 connected by bolts, a clamping member A108, a spring body 109, and a clamping member B105. The housing B107 is installed on the base 9. The housing A101 and the housing B107 are both provided with wire passing holes 102. The clamping member A108 and the clamping member B105 are distributed at the upper and lower ends of the wire passing hole 102 of the housing A101. A driving head 103 is fixedly arranged at the top end of the clamping member A108. The clamping member A108 is slidably arranged in a chute in the inner cavity of the housing B107. The spring body 109 is located at the top end of the clamping member A108. The spring body 109 is clamped in the chute in the inner cavity of the housing B107. The clamping member B105 is located below the clamping member A108. A sliding column 110 is threadedly connected to the surface of the driving head 103, and the sliding column 110 is clamped in the track groove 1002.

[0031] In a specific embodiment of the present utility model, when the Uster seat in this embodiment is in use, the yarn passes through the wire passing holes 102 of the yarn clamp 1 in sequence. When the Uster seat is idle, the sliding column 110 of the yarn clamp 1 is located at the lowest point on the lower wall in the middle of the track groove 1002 (as Figure 1As shown), at this time, the arc groove 106 of the clamping part A108 is in contact with the clamping part B105, and is in a state of clamping the yarn. When the Uss seat operates normally, the knitting machine bridge is located between the two horn blocks 2. When the knitting machine bridge drives the sliding part 10 to move to the right, the sliding column 110 of the yarn clamp 1 slides and rises along the left side of the track groove 1002, and the sliding column 110 links the clamping part A108 to rise, the spring body 109 is compressed, the return spring B6 is stretched, and the return spring A is compressed. At this time, the clamping The arc groove 106 of the part A108 is loosened from the clamping part B105, and the yarn is in a loosened state at this time. When the knitting machine bridge drives the sliding part 10 to move to the left until the sliding post 110 is located at the lowest point of the lower wall in the middle of the track groove 1002, the yarn is clamped again. Then the knitting machine bridge drives the sliding part 10 to continue to move to the left, and the sliding post 110 of the yarn clamp 1 slides and rises along the right side of the track groove 1002, and then the yarn is in a loosened state again, thereby continuously conveying the yarn.

[0032] When a knitting machine bridge fails and causes the sliding post 110 of the yarn clamp 1 to always be located at the lowest point of the lower wall in the middle of the track groove 1002 or the line needs to be changed, the sliding member 10 can be manually moved through the limit rod structure 3, and then the limit rod 301 is pressed to make the limit rod 301 and the horizontal baffle 401 of the folding piece A4 limit and cooperate. At this time, the thread passing hole of the yarn clamp 1 under the folding piece A4 is in a loose thread state. When the Us seat fails or the line is changed, the employee can free one hand to perform the threading operation. After the threading is completed, the limit of the folding piece A4 can be quickly released, thereby quickly resuming the work of the Us seat;

[0033] When it is necessary to adjust the reciprocating motion stroke of the knitting machine bridge driving slide 10 to adjust the clothing style of the knitting machine, the horn block bolt 201 can be loosened, and the distance between the two horn blocks 2 can be adjusted within the range of the adjustment groove 1001. After the distance is determined, the horn block bolt 201 can be tightened to determine the position of the horn block 2. By adjusting the distance between the two horn blocks 2, the function of adjusting the reciprocating motion stroke of the knitting machine bridge driving slide 10 can be achieved.

[0034] In the preferred technical solution, the limiting rod 301 passes through the sleeve 303 and the circumferential end face of the sliding member 10 and is clamped with a clamp. The limiting rod 301 is horizontally aligned with the cross baffle 401. The clamp is provided to prevent the limiting rod 301 from easily slipping out of the sleeve 303.

[0035] In the preferred technical solution, a transverse groove is provided on the surface of the sliding member 10, and bolts are slidably embedded in the transverse groove. The bolts inside the transverse groove are threadedly connected to the surface of one side of the base 9, and the bolts cooperate with the transverse groove to realize the sliding connection between the sliding member 10 and the base 9.

[0036] In the preferred technical solution, the lower wall of the track groove 1002 is provided with a concave arc structure along the left and right directions, and the two sliding columns 110 respectively abut against the inner part of the lower wall in the middle part of the two track grooves 1002. When the sliding member 10 moves back and forth laterally, the sliding column 110 slides inside the track groove 1002, thereby linking the clamping member A108 to lift, and regulating the loose clamping state of the arc groove 106 of the clamping member A108 and the clamping member B105.

[0037] In the preferred technical solution, a protective cover 104 made of a flexible material is placed inside the thread hole 102 to reduce the friction force on the yarn when it moves inside the thread hole 102, so as to avoid damage to the yarn.

[0038] In the preferred technical solution, an arc-shaped groove 106 matching with the clamping member B105 is provided at the bottom of the clamping member A108, so as to make the clamping member A108 fit closely with the clamping member B105.

[0039] To summarize, the present application is based on the traditional Wusi seat, and a limit rod structure 3 for temporarily limiting the movement of the folding piece A4 is elastically arranged on one side of the top of the sliding member 10. When the knitting machine bridge fails and causes the sliding column 110 of the yarn clamp 1 to always be located at the lowest point of the lower wall in the middle of the track groove 1002 or when the line needs to be changed, the sliding member 10 can be manually moved by the limit rod structure 3, and then the limit rod 301 is pressed so that the limit rod 301 and the cross baffle 401 of the folding piece A4 are limited and matched. The employee can free one hand to perform the threading operation. After the threading is completed, the limit of the folding piece A4 can be quickly released, thereby quickly resuming the work of the Wusi seat. At the same time, the traditional Wusi seat cannot adjust the reciprocating motion stroke of the knitting machine bridge driving sliding member 10, and can only be replaced by other types of Wusi seats to adjust the spacing between the two horn blocks 2 to achieve the function of adjusting the reciprocating motion stroke of the knitting machine bridge driving sliding member 10, so as to adjust the clothing style of the knitting machine.
