Detailed Description

The technical scheme of the invention is clearly and completely described below by means of specific embodiments in combination with the accompanying drawings.

Referring to fig. 1-7, the present invention provides a huff disc mechanism, comprising: the half disk comprises a half disk base 1, a first channel changing stop 21, a second channel changing stop 22, a first control component 31 and a second control component 32.

The half disc base 1 is provided with an annular track 11, and the track 11 is used for limiting the motion track of the half needle. The first lane-changing stop 21 is telescopically disposed in the track 11 to change the motion track of the half needle, and the first lane-changing stop 21 has a lane-changing direction for changing the stitch of the half needle from moving along the inner edge of the track 11 to moving along the outer edge of the track 11. The second lane-changing stop 22 is telescopically disposed in the track 11 to change the motion track of the half needle, and the first lane-changing stop 21 has a lane-changing direction for changing the stitch of the half needle from moving along the outer edge of the track 11 to moving along the inner edge of the track 11. The first control component 31 is connected with the first lane changing block 21 to control the first lane changing block 21 to stretch and retract. The second control assembly 32 is connected to the second lane change stop 22 to control the expansion and contraction of the second lane change stop 22.

When the half disc mechanism works normally, the stitch of the half needle moves in the track 11, and at this time, the first channel changing stop block 21 and the second channel changing stop block 22 retract into the track 11, as shown in fig. 5 and 6. In the process of knitting socks, the stitch of the half needle moves along the inner edge of the track 11, and when tying is needed, the first lane changing stop block 21 stretches out, so that the stitch of the half needle cannot move along the original movement track, but only moves to the outer edge of the track 11 along the lane changing direction of the first lane changing stop block 21, namely, the movement track of the half needle is changed. When the tying is completed, the first lane changing stop block 21 is retracted, the second lane changing stop block 22 is extended, and then the stitch of the half needle moves to the inner edge of the track 11 along the lane changing direction of the second lane changing stop block 22, that is, the movement track of the half needle returns to the state of normally knitting socks. According to the half disc mechanism, the first channel changing stop block 21 and the second channel changing stop block 22 which are telescopic are arranged, so that the motion track of a half needle can be changed according to the requirement, and the tying quality of socks can be improved. The half disc mechanism has the advantages of simple structure and easy operation, and changes the motion trail of the half needle.

For complex tying, the position of the half needle which needs to be changed is required to be specific. In a further embodiment, the half plate mechanism further comprises a third lane change stop 23 and a third control assembly 33. The third lane-changing stop 23 is telescopically disposed in the track 11 to change the motion path of the half needle, and the third lane-changing stop 23 has a function of changing the stitch of the half needle from a motion along the outer edge of the track 11 to a position motion along the space between the outer edge and the inner edge of the track 11. The third control assembly 33 is connected to the third lane changing stop 23 to control the expansion and contraction of the third lane changing stop 23. Under normal conditions, the third lane-change stop 23 is retracted into the track 11 (as shown in fig. 5 and 6), and the pins of the half needle are moved along the inner or outer edges of the track 11. When complex tying is required to be knitted, if the needle feet of the half needles move along the inner edge of the track 11, the needle feet of the half needles firstly extend through the first lane changing stop block 21 so that the needle feet of the half needles move along the outer edge of the track 11, then the first lane changing stop block 21 retracts, the third lane changing stop block 23 extends, and the needle feet of the half needles move to a position between the outer edge and the inner edge of the track 11 along the lane changing direction of the third lane changing stop block 23. At this time, if the third lane changing block 23 is retracted and the first lane changing block 21 is extended, the stitch of the half needle may be changed to move along the outer edge of the rail 11; if the third lane-changing stop 23 is retracted and the second lane-changing stop 22 is extended, the needle stitch of the half needle may be changed to move along the inner edge of the track 11. It can be seen that the motion trace of the half needle can be changed by controlling the extension or retraction of the first lane changing stop 21, the second lane changing stop 22 and the third lane changing stop 23, respectively, so that a complicated tying is knitted.

It should be understood that the pins of the half needle move along the inner or outer edges of the track 11, and do not mean that the pins are in contact with the inner or outer edges at all times. Referring to fig. 8, a dashed line a indicates a motion trace of the needle stitch of the huff needle along the inner edge of the track 11, and a dashed line B indicates a motion trace of the needle stitch of the huff needle along the outer edge of the track 11. The broken line C in the figure shows the movement trace of the needle stitch of the huff needle along the position between the outer edge and the inner edge of the rail 11. The movement of the half needle is always clockwise as shown in fig. 8.

Referring to fig. 1 and 2, the half disc base 1 is provided with a block accommodating block 4, and the first lane changing block 21, the second lane changing block 22 and the third lane changing block 23 are movably disposed in the block accommodating block 4.

The side wall of the block accommodating block 4 is provided with a plurality of ribs 41. In the braiding process, the braided wire is attached to the side wall of the block accommodating block 4, and the protruding ribs 41 are arranged to avoid the situation that the braided wire is attached to the side wall of the accommodating block and is difficult to move so as to influence braiding, so that the braiding process can be smoothly carried out.

Referring to fig. 1, 3, 9 and 10, the first control unit 31, the second control unit 32 and the third control unit 33 each include: platen 311, spring 312, first cylinder 313 and second cylinder 314.

In the first control unit 31, a pressing plate 311 is connected to the first lane change stop 21. The spring 312 is abutted between the pressing plate 311 and the block accommodating block 4, so as to reset and retract the first lane changing block 21. The first air cylinder 313 is arranged on one side of the pressing plate 311 to push the pressing plate 311 so that the first lane changing stop 21 extends out in half. The second air cylinder 314 is arranged at one side of the pressing plate 311 to push the pressing plate 311 so as to enable the first lane changing stop block 21 to extend out in a full gear.

In the second control unit 32, a pressing plate 311 is connected to the second lane-changing stop 22. A spring 312 is abutted between the pressing plate 311 and the stop block accommodating block so as to reset and retract the second lane changing stop block 22. The first air cylinder 313 is arranged on one side of the pressing plate 311 to push the pressing plate 311 so as to enable the second lane changing stop 22 to extend out in half. The second air cylinder 314 is arranged at one side of the pressing plate 311 to push the pressing plate 311 so as to enable the second lane changing stop 22 to extend out in a full gear.

In the third control unit 33, the pressing plate 311 is connected to the third lane change stop 23. A spring 312 is abutted between the pressing plate 311 and the block accommodating block 4 to return and retract the third lane change block 23. The first air cylinder 313 is arranged on one side of the pressing plate 311 to push the pressing plate 311 so that the third lane changing stop 23 extends out in half. The second air cylinder 314 is arranged at one side of the pressing plate 311 to push the pressing plate 311 so as to enable the third lane changing stop 23 to extend out in a full gear.

The first cylinder 313 and the second cylinder 314 are provided so as to correspond to the stitches of the half needles having both high and low type stitches. When the first lane changing stop 21 (or the second lane changing stop 22 or the third lane changing stop 23) extends out in half, the half needle with high foot can be blocked and the motion track of the half needle can be changed, but the half needle with low foot can not be blocked, and the half needle with low foot can continue to move along the original track. When the first lane changing stop 21 (or the second lane changing stop 22 or the third lane changing stop 23) extends in full gear, the half needles with high feet and low feet can be blocked at the same time, so that the movement track of all the half needles is changed.

Referring to fig. 1 and 2, a schematic structure of the first lane-changing stop 21, the second lane-changing stop 22 and the third lane-changing stop 23 all extending is shown. Please refer to fig. 3 and 4, which are schematic diagrams illustrating the half-shift extension of the first lane-changing stop 21, the second lane-changing stop 22 and the third lane-changing stop 23. Although the first lane-changing stop 21, the second lane-changing stop 22, and the third lane-changing stop 23 are illustrated as being simultaneously fully extended or simultaneously half extended, it is not meant that the first lane-changing stop 21, the second lane-changing stop 22, and the third lane-changing stop 23 need be simultaneously fully extended or simultaneously half extended during the weaving process. In the actual working process, one of the first lane changing stop 21, the second lane changing stop 22 and the third lane changing stop 23 extends in full gear or half gear according to the knitting requirement, so that the motion trail of the half needle is changed. When the huff needle movement track does not need to be changed, the first lane changing block 21, the second lane changing block 22 and the third lane changing block 23 are retracted into the block accommodating block 4 as shown in fig. 5 and 6.

Referring to fig. 10, each of the first control assembly 31, the second control assembly 32 and the third control assembly 33 further includes a spring guide post 322 connected to the pressing plate 311, and one end of the spring 312 is connected to the spring guide post 322; the stopper accommodation block 4 is provided with a spring accommodation groove 412, and the other end of the spring 312 extends into the spring accommodation groove 412. Such a structural design makes the product more compact and easy to install, and the expansion and contraction direction of the spring 312 is not easy to change, so that the movement of the pressing plate 311 can be better controlled.

Referring to fig. 2 and 7, the track 11 is a groove formed on the bottom surface of the huff disc base 1, an inner convex ring 12 is formed on the inner side of the groove, an outer convex ring 13 is formed on the outer side of the groove, one end of the first lane changing stop 21 extends into the inner convex ring 12, and the other end extends to the outer convex ring 13. By the structure, the first lane changing stop block 21 can change lanes more smoothly, the half needle is prevented from being blocked at the corner of the lane changing stop block, and the condition of broken feet of the half needle is reduced. One end of the second channel stopper 22 extends into the outer convex ring 13, and the other end extends into the inner convex ring 12. By the structure, the second lane changing stop block 22 can change lanes more smoothly, the half needle is prevented from being blocked at the corner of the lane changing stop block, and the condition of broken feet of the half needle is reduced. One end of the third lane changing stop 23 extends into the outer convex ring 13, the other end extends towards the inner convex ring 12, and the distance from one end of the third lane changing stop 23, which is close to the inner convex ring 12, to the inner convex ring 12 is larger than the distance from one end of the second lane changing stop 22, which is close to the inner convex ring 12, so that the lane changing direction of the third lane changing stop 23 is ensured to change the stitch of the half needle to move along the position between the outer edge and the inner edge of the track 11 instead of moving along the inner edge. By the structure, the third lane changing stop block 23 can change lanes more smoothly, the half needle is prevented from being blocked at the corner of the lane changing stop block, and the condition of broken feet of the half needle is reduced.

Although the present invention has been described in terms of the preferred embodiments, it is not intended to be limited to the embodiments, and any person skilled in the art can make any possible variations and modifications to the technical solution of the present invention by using the methods and technical matters disclosed above without departing from the spirit and scope of the present invention, so any simple modifications, equivalent variations and modifications to the embodiments described above according to the technical matters of the present invention are within the scope of the technical matters of the present invention.
