DETAILED DESCRIPTION

[0031] In order to make the above-mentioned purposes, technical solutions and advantages of the present application more clear and easy to understand, the present application will be further described in detail below with reference to the drawings and embodiments. It should be understood that the specific embodiments described herein of the present application are only part of the embodiments of the present application, which are only used to explain the present application and do not constitute a limitation of the present application. In the case of no conflict, the embodiments in the present application and the features in the embodiments can be combined with each other.

[0032] Embodiment 1

[0033] As Figures 3-9As shown, the present application provides a combination needle and taker needle cutter, which comprises a combination cutter base 1, a reset device 2, a taker needle cutter assembly 3 and a taker needle assembly 4 arranged in sequence from bottom to top, the taker needle cutter assembly 3 is vertically slidably connected in the combination cutter base 1, the taker needle assembly 4 is fixedly connected above the combination cutter base 1, the combination cutter further comprises a first driving device for driving the taker needle cutter assembly 3 to slide downward, the first driving device cooperates with the reset device 2 to make the taker needle cutter assembly 3 separate downward or abut upward on the taker needle assembly 4, wherein the abutment includes the taker needle cutter 32 of the taker needle cutter assembly 3 and the taker needle cutter 42 of the taker needle assembly 4.

[0034] Specifically, the limitations of the single needle circular hosiery machine in its own structure are reflected in many aspects, and the present application finds through a large number of research analysis and repeated experiments that the taker needle cutter assembly is the most important factor restricting the single needle circular hosiery machine from effectively knitting single-layer turned-up socks, and the present application intends to improve the taker needle cutter assembly to knit single-layer turned-up socks with the effect of double needle by using the single needle circular hosiery machine.

[0035] Taking the more common seven-way knitting system as an example, the needle selection system of the computer hosiery machine is controlled by 1C-6C and 1F seven needle selectors, wherein the 1C needle selection system controls the rubber band knitting, the 2C-6C needle selection system controls the jacquard knitting, and the 1F needle selection system controls the main knitting system. In the prior art, the double-layer turned-up is different from the single-layer turned-up, and when forming knitting, the 2C, 1F knitting system and the half needle system need to be closely matched to perform the starting knitting and the taker knitting. In order to more conveniently describe, the reference will be made to the Chinese utility model patent document with the application number CN201920480028.8 as an example to expand the description. As shown Figure 2 The structure diagram of the taker needle cutter assembly in the prior art corresponding to the document is shown, in which the taker needle cutter assembly has been improved to a certain extent, that is, the taker cutter 42 is additionally integrated on the taker needle cutter assembly 3, but obviously, the single needle circular hosiery machine using the improved taker needle cutter assembly can at most only produce double-layer turned-up socks and invisible socks, and still cannot produce single-layer turned-up socks.

[0036] More specifically, by adopting the combined needle and gripper needle of the present application, the tuck needle 32 of the tuck needle assembly 3 will not only slide horizontally along the radial direction of the dial assembly 5, but also slide vertically along the axial direction of the dial assembly 5, on the basis that the tuck needle 32 and the gripper needle 42 of the dial assembly 5 will slide horizontally along the radial direction of the dial assembly 5. Further, when knitting a single-layer cuff with a double-needle effect, the knitting can be started by the gripper needle 42 of the 2C selection system and then normally looped, while the tuck needle assembly 3 can also slide vertically, so that the needles selected by the 2C selection system will continue to loop in the 1F knitting system after completing the loop withdrawal, the needle pressing and the yarn laying along the tuck needle surface of the tuck needle 32, while the needles not selected by the 2C selection system will also continue to loop in the 1F knitting system after completing the thread taking and moving downward along the needle pressing surface of the tuck needle 32. Thus, the 1C selection system can periodically select the needles to the loop withdrawal height in the "X separates Y" mode, complete the rubber thread laying and the half-loop in the 1C system, and then complete the loop knitting in the 1F system, and the tuck stitch formed by the rubber thread will be a single-layer double-needle effect, until a single-layer cuff is formed after knitting to the specified number of courses.

[0037] Preferably, the tuck needle assembly 3 comprises a tuck needle seat 31, the tuck needle 32 and a tuck needle cover plate 33 stacked from bottom to top, the tuck needle 32 slides horizontally in the tuck needle seat 31 by the second driving device, and the lower end surface of the tuck needle cover plate 33 is attached to the tuck needle 32, and the upper end surface of the tuck needle cover plate 33 is flush with the upper end surface of the tuck needle seat 31.

[0038] Specifically, the tuck needle 32 needs to slide horizontally in the tuck needle assembly 3 and also needs to slide vertically with the tuck needle assembly 3, and the tuck needle cover plate 33 is arranged to fix and limit the vertical direction of the tuck needle 32 without interfering with the horizontal sliding of the tuck needle 32, and is also conducive to the stacking of the gripper needle assembly 4 on the tuck needle assembly 3.

[0039] Preferably, a first recess 311 is horizontally provided in the center of the tuck needle seat 31, a first stepped groove 312 is downwardly provided in the center of the first recess 311, and one of the left and right ends of the tuck needle seat 31 is also vertically provided with a sliding groove 313 for vertical sliding with the combined needle base 1.

[0040] Specifically, the first stepped groove 312 is used for stacking the notch separating needle cutter 32, the first groove 311 is used for clamping the notch separating needle cover plate 33, and the sliding groove 313 is arranged to make the notch separating needle cutter seat 31 have at least three end surfaces which are in abutting arrangement with the combined cutter base 1 when vertically sliding in the combined cutter base 1, thereby facilitating smooth sliding of the notch separating needle assembly 3 during downward separation or upward abutting against the copy needle assembly 4.

[0041] Preferably, the copy needle assembly 4 comprises, from bottom to top, a copy needle cutter seat 41, the copy needle cutter 42 and a copy needle cover plate 43 which are stacked in sequence, the copy needle cutter 42 horizontally slides in the copy needle cutter seat 41 through a third driving device, and the lower end surface of the copy needle cover plate 43 is in abutting arrangement with the copy needle cutter 42 and the copy needle cutter seat 41 after being fixed to the notch separating needle cutter seat 31.

[0042] Specifically, compared with the notch separating needle assembly 3, the copy needle assembly 4 does not need to stack other components, the horizontal sliding of the copy needle cutter 42 in the copy needle assembly 4 is at most abutting against the notch separating needle cutter 32, and therefore the copy needle cover plate 43 only needs to ensure that the vertical direction of the copy needle cutter 42 is fixed and limited.

[0043] Preferably, the combined cutter base 1 comprises a bottom plate 11 and left and right fixed plates 12 and 13 which are arranged on the left and right sides of the bottom plate 11, the left, front and rear end surfaces of the right fixed plate 13 are matched with the sliding groove 313, and the right end surface of the left fixed plate 12 is in abutting arrangement with the left end surface of the combined cutter base 1 and is flush arranged in the front and rear directions.

[0044] Specifically, the left and right fixed plates 12 and 13 can greatly simplify the structure of the combined cutter base 1 and reduce the assembly difficulty of the combined cutter. On one hand, fastening holes can be formed in the left and right fixed plates 12 and 13 to facilitate the fixation of the copy needle assembly 4, and on the other hand, after the notch separating needle assembly 3 is stacked on the combined cutter base 1 through the reset device 2, the notch separating needle assembly 3 can be directly fixed and limited in the front, rear, left and right directions without any manual fastening action.

[0045] Preferably, the left fixed plate 12 comprises a fixed seat 121 which is arranged to extend upward above the center of the left fixed plate 12, and the upper end surface of the fixed seat 121 is flush with the upper end surface of the right fixed plate 13.

[0046] Specifically, the left fixed plate 12 can also be provided with a fastening hole for fixing the middle disc assembly 5, and the fixed seat 121 is beneficial to the left fixed plate 12 to avoid the fastening assembly space for fixing the middle disc assembly 5, and the structure of the fixed seat 121 is also beneficial to the heat dissipation of the needle separating and picking assembly 3, and the manufacturing material of the combined knife base 1 and the needle separating and picking knife base 31 is saved.

[0047] Preferably, any one or more of the first driving device, the second driving device and the third driving device is a cylinder assembly.

[0048] Specifically, the cylinder assembly is used for driving, so that the vertical sliding of the needle separating and picking assembly 3, the horizontal sliding of the needle separating and picking knife 32 and the horizontal sliding of the picking knife 42 are more accurate and stable, and the quality of the knitted socks is guaranteed. The cylinder assembly can be arranged on the needle separating and picking knife base 31 and / or the picking cover plate 43 according to actual needs, and when the first driving device is the cylinder assembly, a reversing structure can be arranged between the picking knife base 41 and the needle separating and picking cover plate 33, so that the force of the cylinder assembly is converted from horizontal input to vertical output.

[0049] Preferably, the combined knife further comprises a limiting top block 6 fixed to the rear end surface of the needle separating and picking knife base 31, the needle separating and picking assembly 3 abuts against the limiting top block 6 when sliding downward, and a limiting column is connected below the limiting top block 6.

[0050] Specifically, the limiting column can be integrally formed with the limiting top block 6 or assembled, and when assembled, the downward extension height of the limiting column can be flexibly adjusted according to needs, and the flexible adjustment range is that the projection line of the lower end surface of the limiting column on the bottom plate 11 can be normally projected on the bottom plate 11, so that the maximum vertical displacement of the needle separating and picking assembly 3 and the reset device 2 are effectively adjusted.
