CNC splicing device for knitting robot

Abstract

The invention relates to a numerical control splicing device for a knitting robot. The numerical control splicing device comprises a splicer base body, wherein a joint nozzle, a yarn fishing rod, a clamping part, a yarn pressing rod, a yarn shearing device, an untwisting tube and a driving mechanism are arranged on the splicer base body, and the driving mechanism used for driving the action of thecorresponding part; the driving part is a stroke controllable air cylinder or electric cylinder, one end of the yarn pressing rod is a yarn fishing end, the other end of the yarn pressing rod is a driving end, the yarn pressing rod is hinged to the splicer base body through a hinge part, a movable end of the air cylinder or the electric cylinder is arranged on the driving end or the hinge part, and the yarn pressing rod is connected with the yarn fishing rod. According to the numerical control splicing device, the swinging of the yarn fishing rod can be realized through the stroke controllable air cylinder or electric cylinder, yarns to be spliced are pressed to a preset position, the telescopic position of the movable end of the air cylinder or the electric cylinder is controllable, within the range of stroke, the position of the movable end of the air cylinder or the electric cylinder can be freely adjusted, so that the end point position of the yarn fishing rod can be freely adjusted within a certain range, and the splicing requirement of different yarns is met.

Description

technical field [0001] The invention relates to a numerically controlled splicing device for a knitting robot. Background technique [0002] The splicing device is an automatic winding machine used to connect bobbins with less capacity to make larger bobbins. The splicing of bobbins is generally carried out in a knotless way. Such as authorized announcement number CN101508394B, in the invention patent application titled "splicer unit and yarn winding machine", a kind of splicer unit is disclosed, which is introduced in paragraphs [0052] to [0068] of the specification of this patent The splicer device is introduced. The splicer device has a splicing nozzle, a yarn pulling rod, a clamping part, a yarn pressing rod, a yarn cutter, an untwisting tube and a dust collector. The specific splicing action is also introduced. The operation of this splicer is relatively stable, in which the yarn pulling rod and the yarn pressing rod are driven by a cam mechanism to realize the clampin...

Problems solved by technology

However, in the traditional structure, after the cam is designed, the stroke of the yarn fishing rod is set accordingly. Since the lengths of the splicing parts of different types of yarns and the pressure requirements of untwisting compressed air are different, in order to meet the needs of different yarns According to the demand, it is necessary to manually adjust the position of the limit block and the pressure setting of the compressed air, or configure multiple different splicing devices. In this case, the adjustment is cumbersome or the cost is high.

And the traditional structure, in order to meet the full untwisting of yarns in different twist directions (such as Z twist and S twist) and realize different untwisting lengths, it is necessary to disassemble the splicer device and untwist the tube It is time-consuming and labor-intensive to make corresponding adjustments.

When the traditional splicer device is installed at a higher position, it will also bring a lot of inconvenience to the adjustment
