Description

[Technical field]

[0001] The utility model relates to the technical field of circular knitting monitoring equipment, in particular to a knitting height monitoring device inside a needle disc of a weft knitting circular machine. [Background technology]

[0002] The weft knitting circular machine has a "needle bed" that is cylindrical or disc-shaped. The knitting needles are inserted into the needle cylinder or "needle disk" for knitting, thereby achieving the processing of the line. The needle disk mechanism of the weft knitting circular machine is mainly composed of a bracket, a needle disk, a triangle, a motor and an upper disk. The knitting needles are inserted into the needle disk fixedly connected to the bracket so that the butts on the knitting needles are located in the slide groove of the triangle, and then the triangle is fixed on the upper disk. The output shaft of the motor set on the bracket is connected to the upper disk through gears, so that the upper disk rotatably connected to the bracket rotates. Once the upper disk rotates, the corresponding triangle will push the knitting needles to slide up and down, thereby achieving the weaving of the line when the knitting needles rise and fall.

[0003] When the needle disc is rotating, the height of the knitting needle will directly affect the tightness and density of the fabric during weaving. In order to prevent the change of the height of the knitting needle when the needle disc is rotating from affecting the finished product of the knitted fabric, personnel generally conduct random inspections on the knitted fabric, and judge the height of the knitting needle when it rises and falls according to the tightness of the fabric during the random inspection. When the knitted fabric is abnormally tight, the personnel need to stop the machine and adjust the height of the triangle according to the tightness of the knitted fabric to avoid the height of the triangle affecting the tightness of the knitted fabric. This method of random inspection depends entirely on the naked eye, and the naked eye will become fatigued when inspecting the fabric at a high working intensity. Once the naked eye is fatigued, it is easy to cause the accuracy of the subsequent knitting needle height adjustment to decrease. At the same time, if Ruo uses random inspection to monitor the knitting needle fluctuation, although it can monitor the knitting needle fluctuation, when the personnel do not conduct random inspections in time, it is easy to cause a large number of fabrics to have tightness that does not meet the requirements during mass production, thereby greatly reducing the quality of fabric production.
