Description

TECHNICAL FIELD

[0001] The utility model relates to the field of toy knitting machine, especially to a toy knitting machine of optimizing sheet knitting mode. BACKGROUND

[0002] The toy knitting machine, specifically the knitting machine, imitates the real knitting principle, replaces the transmission knitting needle manual knitting, so that the player can experience the knitting through simple operation and obtain the knitting result.

[0003] At present, the main body of the toy knitting machine is usually set as a circular ring, and each hook needle will rotate with the needle cylinder when the handle is shaken, and the needle cylinder makes a hooking line movement in the vertical direction. Similar to manual knitting, the toy knitting machine has two modes of circular knitting and sheet knitting. The operation of circular knitting is relatively simple, and only needs to shake the handle in one direction continuously, and each knitting is connected in a circle, which can form a closed circular fabric. Sheet knitting is to shake the handle in a single direction for a certain number of turns, and then shake it in the opposite direction for a certain number of turns, so as to knit in a folding-back manner, which can form a sheet-shaped fabric.

[0004] The existing toy knitting machine performs relatively smoothly during circular knitting, but when sheet knitting is performed, the first end and the last end of the fabric are prone to missing needles and line unhooking. Once these problems occur, the user often needs to disassemble the fabric and re-knit. At the same time, different needle specifications are more prone to instability during sheet knitting.

DETAILED DESCRIPTION

[0032] In order to better illustrate the purpose, technical scheme and advantages of the utility model, the specific implementation of the utility model will be further described in detail below in combination with the drawings and examples. The following examples are used to illustrate the utility model, but not as a limitation on the scope of the utility model.

[0033] As Figs. 1 to 6 shown, it is a kind of toy knitting machine for optimizing sheet weaving mode according to the utility model embodiment. The toy knitting machine mainly includes shell 0 and weaving mechanism arranged in shell 0. Specifically, the weaving mechanism includes outer ring sleeve 21, inner ring sleeve 22, driving needle cylinder 30, hook needle 40, stop ring 50, wire hooking ring 61, wire dividing ring 62, rocker assembly 70, push-pull assembly 80 and wire guide 90.

[0034] Specifically, outer ring sleeve 21, driving needle cylinder 30 and inner ring sleeve 22 are sequentially arranged from outside to inside. Rocker assembly 70 is fixed on outer ring sleeve 21. The outer side of driving needle cylinder 30 is provided with a tooth ring protruding outward, and the output gear of rocker assembly 70 is drivingly connected to the tooth ring of driving needle cylinder 30. With the power generated by user operation of rocker assembly 70, driving needle cylinder 30 will be driven to rotate between outer ring sleeve 21 and inner ring sleeve 22.

[0035] Further, the inner side of the driving needle cylinder 30 is provided with a groove in the circumferential direction, a plurality of hook needles 40 are arranged in the groove of the driving needle cylinder 30, the plurality of hook needles 40 are also distributed in the circumferential direction and can slide in the vertical direction relative to the driving needle cylinder 30, and the hooking ring 61 and the dividing ring 62 are sequentially fixedly sleeved on the driving needle cylinder 30. Thus, with the rotation of the driving needle cylinder 30, each hook needle 40 will also rotate, and the hooking ring 61 and the dividing ring 62 will also rotate.

[0036] Specifically, the outer ring sleeve 21 and the inner ring sleeve 22 are provided with guide rails 23, and the hook needles 40 are clamped in the guide rails 23 to push the hook needles 40 to displace in the vertical direction. Thus, the outer ring sleeve 21 and the inner ring sleeve 22 are fixed and do not move, the driving needle cylinder 30 drives the hook needles 40 to rotate, the guide rails 23 extend in the circumferential direction, and the hook needles 40 are passively kept at the same height as the guide rails 23 in the vertical direction. In most of the circumferential positions, the hook needles 40 are at the lowest point, and when close to the lead wire device 90, the hook needles 40 will displace upward in the vertical direction to hook the wool of the lead wire device 90.

[0037] Further, the stop ring 50 is sleeved on the outer side of the driving needle cylinder 30, is located on the tooth ring of the driving needle cylinder 30, and can rotate and slide relative to the driving needle cylinder 30.

The push-pull assembly 80 is fixed on the shell 0, the push-pull assembly 80 is provided with a limiting key 81, and the push-pull assembly 80 can drive the limiting key 81 to displace in the vertical direction. When the limiting key 81 is displaced to the upper end, on the rotating circumferential direction of the stop ring 50, any side of the first stop block 51 can abut against the limiting key 81, so as to limit the continuous rotation of the stop ring 50 to that side, and the toy knitting machine is in the sheet-shaped knitting mode.

Thus, when the driving needle cylinder 30 rotates, the second stop block 31 of the driving needle cylinder 30 will also rotate and will rotate to abut against the end of the arc-shaped limiting groove 52 of the stop ring 50, and then drive the stop ring 50 to rotate; with the rotation of the driving needle cylinder 30 and the stop ring 50, the first stop block 51 of the stop ring 50 will also rotate and will rotate to abut against the limiting key 81.

[0039] In the embodiment, the driving needle cylinder 30, the stop ring 50 and the limiting key 81 cooperate with each other, so that the rotation angle of the driving needle cylinder 30 from one limiting position to another limiting position is one circle plus two hook needle 40 interval angles, and the rotation angle can be adjusted by plus or minus two degrees.
