Yarn-passing alarm panel for embroidery machine

Abstract

The invention discloses a yarn-passing alarm panel for an embroidery machine, comprising a base board. Yarn trappers, a yarn-passing detector, a surface tension adjustor and a yarn-passing nail are arranged on the base board; a yarn trapping sheet in the upper yarn trapper is used for pressing embroidery yarn through constant pressure; a yarn-passing wheel and a light shielding piece are installed on a ball bearing through a shaft pin, so that the yarn-passing wheel and the light shielding piece can be driven to rotate more smoothly by the embroidery yarn, and the damping coefficient is lower; the tension of the embroidery yarn and integral tension can be more conveniently and effectively adjusted to be uniform by the single surface tension adjustor; the embroidery yarn is also pressed by a yarn trapping sheet in the lower yarn trapper through constant pressure; the shaking of the embroidery machine, which is generated during taking up the yarn in the embroidering process, can not influence an area between the upper yarn trapper and the lower yarn trapper, so that tensile force well adjusted by the surface tension adjustor can be stably output; and when the embroidery yarn does not shake, the light shielding piece rotates more smoothly, and the detection of the light shielding piece, which is carried out through electronic control, can be more accurate, thereby solving the defect of frequent misinformation of an yarn-passing base board of an original embroidery machine even by adopting two detection points.

Description

[0001] technical field [0002] The invention relates to a thread passing panel of an embroidery machine, in particular to a thread passing alarm panel of an embroidery machine. Background technique [0003] Existing embroidery machine line crossing alarm panel such as figure 1 with figure 2 The structure shown is also seen in Chinese utility model patent ZL200720173236, which mainly includes a base plate 101. The base plate 101 is provided with an upper adjusting thread gripper 121, a thread passing detector, an upper thread tension regulator 122 and a ceramic thread passing seed 104, 105, 108, 109. [0004] The embroidery thread 103 passes through the upper adjusting thread clamp 121, and the upper adjusting thread clamp 121 is composed of an adjusting nut 110, a spring 111, two thread clamping pieces 112, and a thread passing piece 113, and the rotating adjusting nut 110 compresses or loosens the spring 111 so that Two thread clamping sheets 112 press down the embro...

Problems solved by technology

[0009] The purpose of the present invention is to overcome the disadvantages of the thread-passing alarm panel of the prior art embroidery machine, such as troublesome and inconsistent tension adjustment, frequent false alarms, and heavy threading workload, to provide a relatively simple structure. , The threading workload is greatly reduced, the thread tension is easy to adjust, can be adjusted consistently, and the probability of false alarms is greatly reduced on the embroidery machine's thread alarm panel
