Description

TECHNICAL FIELD

[0001] The utility model relates to braiding machine technical field, especially a kind of anti-laddering device for the braiding machine for producing large-hole breathable socks. BACKGROUND

[0002] In sock production, large-hole breathable socks are favored by the market due to their excellent comfort and breathability, but traditional hosiery machines face multiple technical challenges in realizing this special structure. First, due to the fewer yarn contact points of the large-hole structure, traditional looping methods cannot effectively secure the yarn, leading to easy yarn slippage during wear or washing, and conventional anti-laddering solutions (such as increasing yarn density) significantly reduce the breathability of the socks, making it difficult to balance functionality and comfort. Second, insufficient mechanical coordination is also a key factor - asynchronous action of the comb and needle bed causes yarn positioning deviation, resulting in irregular hole shapes or local looseness, and during high-speed knitting, mechanism vibration also causes uneven yarn tension, severely affecting product quality. In addition, traditional equipment has obvious defects in material and structural design: connecting rods are prone to deformation, leading to a decline in movement precision over time, requiring frequent calibration and maintenance; more critically, there is a lack of effective one-way transmission protection mechanism, and accidental needle bed rollback can easily cause the loosening of the knitted part. These systematic technical bottlenecks severely restrict the production efficiency and product quality improvement of large-hole breathable socks.

[0003] A Chinese patent discloses a ribbon weaving transmission device for a braiding machine (Publication No. CN 205803754U) including a gripper, a connecting rod, a reciprocating controller, a slider, a guide rail, a base plate, and a fixed plate; the gripper is connected to the slider, the slider is slidingly connected to the guide rail, the guide rail is fixed to the base plate, the reciprocating controller is connected to the base plate through the fixed plate, and a connecting rod is connected between the gripper and the reciprocating controller; the gripper has a clamping plate, and there are two clamping claws at the front end of the gripper. However, this braiding machine has key technical defects such as yarn easy to scatter, irregular hole shape, mechanical movement out of sync, material easy to deform, and lack of anti-backup protection when weaving large-hole breathable socks, so a braiding machine anti-laddering device for producing large-hole breathable socks is needed.

In terms of anti-slip performance, the unique cooperation of the radial connecting rod and the Y-shaped frame of the comb transverse movement mechanism ensures accurate positioning and uniform distribution of the yarn during weaving, effectively avoiding loose or slipping of the yarn at the edge of the large eye. At the same time, through the cooperative control of the 90°-120° phase difference between the comb transverse movement mechanism and the needle bed mechanism, the yarn is first accurately positioned and then looped, forming a tight interlacing structure, which fundamentally prevents the edge of the eye from slipping. In addition, the design of the anti-slip one-way ratchet ensures the irreversibility of the needle bed mechanism action, completely eliminating the problem of loop loosening caused by mechanical backtracking during weaving. In terms of weaving quality and efficiency optimization, the innovative symmetrical sparse node design realizes dynamic balance of yarn tension through double sparse node synchronous action, significantly reducing yarn deviation or breakage during weaving, and significantly improving the consistency of eye shape.

The adjustable knock-over plate and adjustment seat equipped in the needle bed mechanism support quick switching of different yarn thickness and eye size, enabling the device to flexibly adapt to diversified production needs. In terms of equipment reliability and maintenance convenience, the key components such as the comb transverse movement mechanism and the needle bed mechanism are designed in a modular manner, facilitating quick disassembly, maintenance or replacement of worn parts. At the same time, key transmission components such as cam rocker arms and ratchets are made of high-wear-resistant materials, effectively reducing equipment failure rate and significantly prolonging overall service life. The synergistic effect of these innovative designs enables the device to ensure the air permeability of large eyes while improving the anti-slip performance, weaving precision and production efficiency.

[0025] The implementation principle of the embodiment is:

[0026] Starting stage (the pattern chain wheel 7 drives the whole system)

[0027] When the knitting machine starts to work, the pattern chain wheel 7 (mounted on the machine frame plate 9) rotates through the chain wheel shaft 8, drives the swing lever 6 connected therewith to swing left and right;

[0028] Yarn unwinding stage (action of the sparse section 1 and the comb section transverse movement mechanism)

[0029] When the swing lever 6 swings, it pushes the support rod, and the support rod in turn drives the two symmetrical sparse sections 1 to move. The sparse section 1 is mounted with the comb section transverse movement mechanism, and the core of the mechanism is the Y-shaped metal frame 23. The top of the frame is provided with a cam mounting groove 24 and a cam shaft 2 for controlling the movement rhythm. When the comb section transverse movement mechanism starts to work, the radial connecting rods 22 (arranged at 15°) thereof will stretch outward, evenly stretching the yarn and forming the outline of a large eye;

[0030] Yarn loop forming stage (needle bed mechanism starts to work)

[0031] After the yarn is positioned by the comb section transverse movement mechanism, the following needle bed mechanism starts to work. The needle bed mechanism includes: a knock-over plate 4 (for controlling yarn knock-over); a latch needle 3 (for hooking the yarn to form a loop); a steel wire seat (for assisting in fixing the position of the yarn); an adjustment seat 10 (for adjusting the height of the needle bed); a needle bed movable seat 17 (for driving the needle bed to move up and down); and a needle bed guide seat 18 (for ensuring stable movement).

[0032] When the needle bed mechanism works, the needle bed connecting rod 16 pushes the first cam rocker arm 19, the rocker arm in turn drives the anti-disintegration one-way ratchet wheel 20 (to prevent the needle bed from back-off), and finally adjusts the position of the needle bed through the second cam rocker arm 21 and the connecting rod rocker arm 14, to ensure that the yarn is firmly hooked and forms a tight loop.

[0033] 4. Anti-disintegration reinforcement stage (phase difference control)

[0034] The action of the comb section transverse movement mechanism and the needle bed mechanism is not simultaneous, but has a phase difference of 90°-120°. That is to say, the comb section first pulls the yarn into position, and then the needle bed acts to compact the yarn. In this way, the yarn will not be loose at the edge of the eye, and the large eye can also maintain stable shape;

[0035] 5. Looping phase (continuous operation)

[0036] The whole system repeats continuously: the pattern chain wheel 7 drives the swing lever 6 → the support rod pushes the sparse section 1 → the comb section transverse movement mechanism spreads the yarn → the needle bed mechanism compacts the loop → the one-way ratchet prevents backtracking → the next needle continues to weave.
