Description
Technical Field
The invention belongs to the field of knitting machinery, and particularly relates to a double-cylinder stocking machine and a method for knitting a stocking opening by using the double-cylinder stocking machine.
Background
The double-needle-cylinder hosiery machine is provided with an upper needle cylinder and a lower needle cylinder, guide needle sheets are respectively arranged in grooves of the upper needle cylinder and the lower needle cylinder, a loop forming part for finishing knitting is a double-head latch needle, and two ends of the double-head latch needle can be respectively matched with the upper guide needle sheet and the lower guide needle sheet for knitting a front coil or a back coil. Because of this property, it is possible to weave more complex fabric types.
On the other hand, in the case of knitting the first rows of stitches of the welt, it is necessary to use a needle-separated knitting method, i.e. only one of the two adjacent needles takes part in the knitting. In the case of a double cylinder, one of the two adjacent double-ended latch needles needs to be connected with an upper guide needle sheet, and the other one needs to be connected with a lower guide needle sheet. In the prior art, in order to achieve this function, a needle selecting mechanism which is the same as that of the lower needle cylinder is generally arranged on the upper needle cylinder, and the guide needle sheet on the upper needle cylinder is selected at intervals so as to be matched with or separated from the double-headed latch needle. This is in fact a wasteful practice, since jacquard knitting is generally carried out with double-ended latch needles in the lower needle cylinder, the upper needle cylinder does not require a needle selection mechanism which can be selected at will, and only the upper needle cylinder is required to have the double-ended latch needles in two states of the same height or different heights at intervals, so that the prior art practice is equivalent to killing chickens with a cow knife, which leads to an increase in manufacturing cost and maintenance cost.

Detailed Description
See fig. 1. The double-needle-cylinder sock machine comprises a machine table 1, wherein a cylinder 2 and a lower needle cylinder 5 are arranged on the machine table, the lower needle cylinder 5 can rotate around the axis of the lower needle cylinder, a main shaft is arranged in the cylinder and used for driving a cantilever 3 at the upper end of the cylinder, the other end of the cantilever 3 is provided with an upper needle cylinder 4, and the rotation of the cantilever drives the upper needle cylinder to perform circular arc motion, so that the upper needle cylinder and the lower needle cylinder are coaxial or not coaxial. In the operating condition, the upper needle cylinder 4 is coaxial with the lower needle cylinder 5 and rotates synchronously along its own axis.
The upper needle cylinder is externally surrounded by an upper steel ring 40, the lower needle cylinder is externally surrounded by a lower steel ring 50, the upper steel ring and the lower steel ring are collectively called as a whole, each are formed by splicing a plurality of parts, and a plurality of tracks and cams are formed in each part. The two steel rings are the prior art, and the innovation related to the invention is described in detail below. Wherein, a plurality of electromagnetic needle separators 7 are arranged outside the lower steel ring, and the front end of the electromagnetic needle separators is provided with a cutter head which can extend or retract towards the axial direction of the lower needle cylinder according to the command.
See fig. 2. The outer wall of the upper needle cylinder 4 is provided with an axial groove, a braiding part of the upper needle cylinder is arranged in the upper needle cylinder, the upper guide needle sheet 41, the upper control sheet 42 and the tabletting 431 or 432 are respectively arranged from bottom to top, wherein the upper end of the upper guide needle sheet 41 is provided with an inverted trapezoid protruding end 412, the lower end of the upper control sheet is provided with an inverted trapezoid recessed end 422, the protruding end 412 is mutually embedded with the recessed end 422, and the upper guide needle sheet 41 and the upper control sheet 42 are respectively provided with heels 411 and 421. The preforms are divided into two types, designated first preform 431 and second preform 432, both having a heel 433, with the difference that the first preform 431 continues to extend downwardly below the heel 433 to form a T-shape, while the second preform 432 does not have a portion below the heel 433, thus forming an L-shape. The two types of pressing sheets are arranged at intervals in the circumferential direction, namely, in one axial groove of the upper needle cylinder, the upper guide needle sheet 41, the upper control sheet 42 and the pressing sheet 431 are arranged in the adjacent axial grooves, and the upper guide needle sheet 41, the upper control sheet 42 and the pressing sheet 432 are arranged in a staggered manner.
The outer wall of the lower needle cylinder 5 is also provided with an axial groove, a knitting part of the lower needle cylinder is internally provided with a lower guide needle sheet 51, a lower control sheet 52 and a needle selecting sheet 53 from top to bottom, wherein the lower end of the lower guide needle sheet 51 is provided with an inverted trapezoid protruding end 512, the upper end of the lower control sheet is provided with an inverted trapezoid recessed end 522, the protruding end 512 is mutually embedded with the recessed end 522, and the lower guide needle sheet 51 and the lower control sheet 52 are respectively provided with heels 511 and 521. The selector blade 53 has a body with an outwardly extending elongate resilient cantilevered end 531 with a heel 532 and radial force-bearing ends 533 on opposite sides of the cantilevered end that are adapted to be urged against the radial force-bearing ends 533 when the bit of the electromagnetic selector 7 is extended.
The double-ended latch needle 9 is arranged between the upper guide needle sheet 41 and the lower guide needle sheet 51, namely between the upper needle cylinder 4 and the lower needle cylinder 5, and is combined with the upper guide needle sheet 41 or the lower guide needle sheet 51 according to the requirement so as to realize different knitting requirements.
The inner wall of the upper steel ring has several rails and cams at different heights, such as cams 461, 462, 463, 464, acting on the heel 421 to push the upper control blade 42 up or down, and other cams acting on the heel 411 of the upper slider, or on the recess 422 of the upper control blade, or on the lower end of the upper slider, giving the upper slider or upper control blade axial or radial force to generate axial or radial movement, in any case by the design of the geometry of the specific cams. It should be noted that the inner wall of the upper steel ring has a track 47 for accommodating the presser heel 433, which is a complete circumferential track, and includes a bifurcated track 471 higher than the track 47, and is connected to the track 47 by an ascending section and a descending section.
When knitting the initial rows of stitches of the welt, the cam 462 is used to act on the heel 421 to make the knitting member of the upper needle cylinder move upwards, the heel 433 of the presser is lifted up to enter the bifurcation track 471, and when the presser returns to the track 47 from the bifurcation track 471, the presser descends, at this time, the lower end of the presser 431 contacts the upper control piece 42 to press the upper control piece 42 together with the upper guide needle piece 41, and the presser 432 cannot contact the upper control piece 42, so that the corresponding upper control piece 42 and upper guide needle piece 41 still operate at the original height. That is, the heights of the two upper guide pins in the adjacent axial grooves are not consistent in the circumferential direction, and finally, the heights of the two adjacent double-head latch pins are not consistent and staggered.
The lower rim is similar to the upper rim, and cams 551, 552, 553, 554, 555, 561, etc. act on the heel 521 of the lower control blade or the heel 511 of the lower slider to cause it to rise or fall in the axial direction. The selector 53 is matched with the electromagnetic selector 7, when the cutter head of the electromagnetic selector is propped against the radial stress end 533 of the selector, the selector is pressed towards the axial direction of the lower needle cylinder, so that the elastic cantilever end 531 is pressed and bent, the heel 532 of the selector is staggered with the corresponding track and cannot generate axial movement, when the cutter head of the electromagnetic selector is separated, the elastic force of the elastic cantilever end 531 enables the heel 532 to enter the corresponding track and move along the track, and when the selector 53 is lifted, the propped lower control plate 52 and the lower guide plate 51 are lifted to a higher position, so that a second cam (not shown in the figure) in the lower steel ring can act on the concave part 522 of the lower control plate, or a first cam (not shown in the figure) in the lower steel ring can act on the upper end of the lower guide plate 51, and thus the lower guide plate 51 can generate radial movement to be matched with or separated from the double-headed needle tongue.
The above description shows that the radial swing of the lower guide pin sheet and the action of the double-head latch pin can be caused only in the selected axial groove through the ascending of the needle selecting sheet, and the needle selecting mode is simple and efficient.
