Three-shed shedding mechanism for rotary electronic dobby

Abstract

The invention relates to a three-shed shedding mechanism for a rotary electronic dobby, belonging to the technical field of the textile machinery.The rotary electronic dobby comprises a splined main shaft, and the three-shed shedding mechanism comprises one pair of signal device and a heald lifting device, wherein the heald lifting device comprises a heald lifting arm and a heald lifting arm shaft and is connected with the signal device. The three-shed shedding mechanism is characterized in that the heald lifting device also comprises a rear oscillating disc connecting base, a front oscillating disc connecting rod, a front oscillating disc and a rear oscillating disc. Due to the adoption of the technical scheme, the three-shed shedding mechanism can meet the requirement of shedding three weaving sheds for weaving double-layer textile by a weaving machine. The three-shed shedding mechanism has simple structure and low manufacturing and modifying cost.

Description

technical field [0001] The invention belongs to the technical field of textile machinery, and in particular relates to a three-slot opening mechanism of a rotary electronic dobby, which is used to form a weaving shed of a heald frame required for double-layer weaving of a loom. Background technique [0002] The rotary electronic dobby is also referred to as the rotary dobby for short. The concept of the rotary dobby has long been seen in documents such as Chinese patent documents, such as Chinese invention patent application publication number CN1186879A. [0003] As known in the textile industry, the grade of fleece fabric belonging to the category of fabric fabrics is relatively high, and its uses are also very extensive. It can be used not only as clothing fabrics, but also as bedding fabrics, handicraft decoration fabrics and As plush, faux fur and fur etc. There are many methods of weaving pile fabrics, but the most commonly used method is the double-layer split method...

AI Technical Summary

Problems solved by technology

[0006] by the above Image 6 As can be seen from the description, although the loom weaving shed opening mechanism of the rotary electronic dobby in the prior art has the advantages of mechatronics, convenience for turning over and changing varieties, positive return and high speed as mentioned by the applicant , but it is undoubtedly a big shortcoming that it cannot meet the three shed requirements required for the weaving shed of the loom. The final result is that it restricts the weaving of double-layer fabrics such as the aforementioned pile fabric

If the loom weaving shed shed mechanism of the rotary electronic dobby of the aforementioned structure is abandoned and a loom weaving shed mechanism specially made by a professional manufacturer is adopted, then in addition to the problems that cannot reflect electronization, high speed and energy saving, It also leads to a waste of resources
