Problems solved by technology

In this way, the final overall design will be quite complicated, and it will also increase the manufacturing cost and installation difficulty
In addition, when the cam device is running, due to lint, oil, electronic control failure or other factors, it will often cause this kind of action cam to be insensitive or even stuck, which increases the failure rate and causes a large number of knitting needles to be damaged. Directly affect the economic benefits of users
The cam system of the flat knitting machine in the prior art is complex in structure, difficult to manufacture, low in stability and low in work efficiency

Embodiment 1

[0032] A kind of knitting device 100 of weft knitted fabric, such as figure 1 Shown, comprise: needle plate 1, latch needle 2, and main controller 3; Needle plate is installed on the frame of loom; Latch needle is arranged in the needle groove, and described needle butt (22) is installed on latch needle ( 2) The tail part also includes: a baffle plate 4, a spring 5, a connecting wire 6, and a stepping motor 7 connected to the main controller. in,

[0033] The baffle plate is fixed on the needle plate at the lower part of the needle butt, the spring is set in the direction of the latch needle, and its two ends are respectively fixed on the needle butt and the baffle plate one by one, the spring is in a compressed state; the stepping motor is located on the needle The lower part of the board; the two ends of the connecting line are connected to the needle butt and the stepping motor in one-to-one correspondence, and the connecting line exerts a pull-down force on the needle but...

Embodiment 2

[0038] On the basis of Embodiment 1, the stepping motor is located directly under the needle plate, and the connecting lines are arranged vertically.

[0039] The direction of the connecting wire and the latch needle is the same, both are in the vertical direction, and the structure is simple, which can further speed up the loop forming time and reduce power consumption.

Embodiment 3

[0041] On the basis of Embodiment 1 or Embodiment 2, the stepper motor 7 includes a rotary head 71; the two ends of the connecting wire are respectively connected to the needle butt and the rotary head in one-to-one correspondence, and the connecting wire is connected to the forward or reverse rotation of the rotary head. Driven by it, a pulling force is applied to the needle heel.

[0042] The release and contraction of the connecting wires are driven by the turning head, which is convenient and quick, simple in structure and low in cost.

Abstract

The invention relates to a loop forming device and method for weft knitted fabric. The device comprises a needle plate, a latch needle, a main controller, a baffle, a spring, a connecting wire, and astepping motor connected to the main controller. The baffle is fixed at a position of the needle plate at a lower portion of the butt joint. The spring is arranged according to the direction of the latch needle, and the two ends are respectively fixed to the needle joint connector and the baffle in a one-to-one correspondence. The spring is in a compressed state; the stepping motor is located at alower portion of the needle plate; the two ends of the connecting wire are respectively connected to the pin connector and the stepping motor in a one-to-one correspondence. The connecting line is driven by the stepping motor to apply a pulling force to the butt joint, and the pulling force is greater than or equal to 0; the initial horizontal position of the tip of the latch needle is located atthe lower portion where the float height is formed. The device replaces the traditional triangular control by the stepping motor control, and avoids problems such as collision and friction between the triangular forming parts. The knitting needle can be reduced in looping time; the knitting speed of the computer flat knitting machine is improved with simple structure and low cost.

Description

technical field [0001] The invention relates to the technical field of weft-knitted fabric weaving, in particular to a weft-knitted fabric knitting device and a knitting method thereof. Background technique [0002] When weaving computerized flat knitting fabrics, according to the needs of the pattern process, the knitting cam and the transfer cam need to be frequently switched, and the position of the corresponding pressing sheet must also be changed. Whether it is the action of the triangle or the change of the tablet pressing position, it must be completed under the control of the electromagnet or other similar electronic control devices by a flexible auxiliary mechanism. In this way, the final overall design will be quite complicated, and it will also increase the manufacturing cost and installation difficulty. In addition, when the cam device is running, due to lint, oil, electronic control failure or other factors, this kind of action cam is often insensitive or even ...
