AI Technical Summary
During the knitting process of a sock machine, if the angle between the yarn feeders cannot be widened, it will cause the yarn to reverse, resulting in a disordered pattern on the socks.
By designing a yarn feeder control structure, the position of the yarn feeder is controlled by the first and second driving components, including the upper, lower and half positions, to ensure that the yarn feeder remains in the half position after yarn feeding to open the angle. Combined with the full and half position pistons, adjusting screws and other components, the movement trajectory of the yarn feeder is adjusted to solve the yarn feeding problem.
It effectively solves the problem of reversed yarn in sock knitting, ensuring that the yarn can smoothly enter the needle hook during the knitting process, avoiding pattern confusion, and improving the quality of sock knitting.

Abstract
Description
Technical Field
[0001] This utility model relates to the field of sock machines, and specifically refers to a yarn feeder control structure for sock machines. Background Technology
[0002] Sock knitting machines can be classified according to the needle bed type, needle type, and number of cylinders (beds). The basic structure of a circular knitting machine includes a cylindrical cylinder with several needles arranged on its outer circumference. The movement of these needles weaves the yarn into loops, eventually forming a complete sock. A steel ring surrounds the upper part of the cylinder, and various components are arranged along this ring. These components work in conjunction with the needles or yarn as needed, acting on the yarn to perform various knitting movements. Additionally, various components that coordinate with the needle movements are located in the middle and lower outer periphery of the cylinder.
[0003] During knitting, yarn needs to be fed in so that the needle hook can catch it. The yarn is transported through the yarn feeder. However, if the yarn feeding angle (depth) between the two yarn feeders cannot be widened during knitting, it will cause the yarn to reverse, resulting in the sock pattern being disordered. The inventor conducted further research on this issue and developed a yarn feeder control structure for sock knitting machines, which led to this invention. Utility Model Content
[0004] The purpose of this invention is to provide a yarn nozzle control structure for a sock machine, which effectively solves the problem of yarn reversal by driving and controlling the yarn nozzle.
[0005] To achieve the above objectives, the technical solution of this utility model is as follows:
[0006] A yarn feeder control structure for a sock knitting machine, comprising:
[0007] The yarn feeder is in a lower position and close to the needle hook when driven by the first driving component, in a half position when driven by the second driving component, and in an upper position when not driven by the driving component. The half position is between the upper and lower positions. When the yarn feeder is in the upper position, it does not feed yarn; when it is in the lower position, it feeds yarn to the knitting needle; and when it is in the half position, it is in a yarn-eating state.
[0008] This allows the yarn feeder to remain in a semi-position after feeding yarn, thus creating an angle with the front (rear) yarn feeder. Yarn feeding refers to the state of the yarn feeder after feeding yarn to the knitting needle.
[0009] Furthermore, the yarn feeder is pivotally connected in the yarn feeder seat, and the working parts of the first driving member and the second driving member are both located below the tail end of the yarn feeder.
[0010] Taking the position of the yarn feeder head as the front end, the other end corresponding to the pivot point of the yarn feeder head is the tail end. The relative position of the yarn feeder head is changed by driving the tail end of the yarn feeder head.
[0011] Furthermore, the first driving component is a full-position piston, which drives the tail end of the yarn nozzle from bottom to top.
[0012] Furthermore, the second driving component is a half-position piston, which is arranged laterally and drives the half-position swing block to push the tail end of the yarn nozzle to move.
[0013] Furthermore, a reset rod is provided above the tail end of the yarn feeder, and the reset rod, together with the reset spring, abuts against the tail end of the yarn feeder.
[0014] After the full-position piston removes its force, the reset spring, in conjunction with the half-position piston, keeps the yarn nozzle in the half-position state.
[0015] Furthermore, the yarn feeder includes a yarn feeder head and a yarn feeder rod. The yarn feeder head can move relative to the yarn feeder rod, and a yarn feeder compression spring is provided between the yarn feeder head and the yarn feeder rod. A forward adjustment screw is also provided below the yarn feeder. When the yarn feeder descends to the lower position, the yarn feeder head is limited by the forward adjustment screw and moves forward.
[0016] Moving the adjusting screw forward allows the yarn nozzle to extend further when it descends to the lower position. When the yarn nozzle rises to the half position, the adjusting screw moves forward to disengage from the yarn nozzle head, causing the yarn nozzle head to retract and further widening the angle between the yarns.
[0017] Furthermore, a full-position adjustment screw is also provided above the tail end of the yarn feeder.
[0018] The full-position adjustment screw can limit the descent depth of the yarn feeder tip.
[0019] Furthermore, a half-position adjustment screw is also provided above the half-position swing block.
[0020] The half-position adjustment screw is used to limit the half-position height of the yarn feeder.
[0021] By adopting the above solution, this utility model has the following advantages compared with the prior art:
[0022] It can effectively solve the quality problem of reversed yarn in sock knitting: when the yarn feeder enters the yarn feeding state, the yarn feeder is lowered to a low position close to the needle hook so that the needle hook can hook the yarn. Then it is raised and moved back to open the angle between the yarn feeder and the front yarn feeder. In this way, the yarn feeder angle of the two yarn feeders is opened, which can solve the reversed yarn problem. Attached Figure Description

[0033] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.
[0034] like Figure 1 , Figure 2 As shown, a yarn feeder control structure for a sock knitting machine includes a yarn feeder 1, which is oscillatingly mounted in a yarn feeder seat. The front end of the yarn feeder 1 is a yarn feeder head 11, which is slidably mounted in a yarn feeder rod 12. A pressure spring cover and a yarn feeder head pressure spring 14 are provided on the yarn feeder head 11. A forward adjustment screw 9 is provided below the yarn feeder. When the yarn feeder 1 oscillates downward, the yarn feeder head 11 is subjected to a relative thrust from the forward adjustment screw 9, causing the yarn feeder head 11 and the yarn feeder rod 12 to move towards each other, and the pressure spring is compressed. The deformation of the yarn feeder head pressure spring 14 when the yarn feeder oscillates downward can also be changed by adjusting the forward adjustment screw 9 itself.
[0035] A reset rod 3 is provided above the tail end of the yarn nozzle, and a full-position piston 6 is provided below in cooperation with the reset rod 3. When the full-position piston 6 moves upward, it can push the yarn nozzle head 11 to swing downward, and the reset spring 2 on the reset rod 3 is compressed. When the full-position piston 6 retracts, the reset rod 3 enables the yarn nozzle to reset under the action of the reset spring 2.
[0036] A half-position swing block 7 is also provided on the right side of the full-position piston 6. The half-position swing block 7 is pivotally connected to the tail end of the yarn feeder. It is pushed by the half-position piston 8, so that the half-position swing block 7 has the ability to push upward from the tail end of the yarn feeder.
[0037] Its working principle is as follows:
[0038] Taking one of the yarn feeders as an example, when yarn feeder 1 is in the upper position, such as Figure 3 As shown, the yarn feed spring and the return spring 2 are in the extended state. When the full-position piston 6 moves upward, as... Figure 4As shown, the tail end of the yarn feeder is pushed upward, and the reset rod 3 is pushed upward, thereby compressing the reset spring 2. At the same time, the yarn feeder head 11 descends and its right end touches the forward adjustment screw 9, causing the yarn feeder head 11 to extend forward relatively. At this time, the yarn feeder head spring 14 is compressed with the cooperation of the spring cover. The yarn feeder enters the yarn feeding state.
[0039] After the yarn feeding is completed, the half-position piston 8 pushes out to the left, the full-position piston 6 closes, and the half-position swing support yarn nozzle 1 is in the half-position state. At this time, the yarn nozzle head 11 disengages from the forward adjustment screw 9, the yarn nozzle head 11 rises and retracts under the action of the yarn nozzle head compression spring 14, so that the two yarn nozzles can be pulled apart at a certain angle when feeding yarn.
[0040] Meanwhile, a full-position adjusting screw 4 and a half-position adjusting screw 5 are respectively provided at the tail end of the yarn nozzle and above the half-position swing block 7. The full-position adjusting screw 4 is used to limit the position of the yarn nozzle when the full-position piston 6 is pushed up, and the half-position adjusting screw 5 is used to limit the swing amplitude of the half-position swing block 7. The ultimate purpose of both is to adjust the position of the yarn nozzle when it is in the lower or half position.
[0041] The above are merely specific embodiments of this utility model. Furthermore, terms such as "upper," "lower," "left," "right," and "middle" used in this utility model are for reference only and are not absolute limitations. Any non-substantial modifications made to this utility model shall be considered as infringing upon the protection scope of this utility model.
