Description

TECHNICAL FIELD

[0001] The utility model relates to cloth production technical field, especially a lace weaving device for cloth production. BACKGROUND

[0002] The traditional lace weaving device for cloth production is various, but generally has the shortcoming of low weaving precision. During the weaving process of cloth, long-distance conveying is required, and the cloth may become damp due to the influence of the workshop environment during conveying, which affects the weaving precision. In addition, the two sides of the cloth are not flattened during weaving, further reducing the aesthetic appearance of the woven cloth.

[0003] To solve the above problems, a lace weaving device for cloth production is disclosed in the patent file with publication number "CN215800281U", which includes a base, side plates, and a top plate. The upper surface of the base is fixedly connected with two side plates, and the upper surface of the side plate is fixedly connected with a top plate. A drying mechanism is fixedly connected to the left side of the left side plate, and a flattening mechanism is fixedly connected to the upper surface of the top plate. The right side of the base is fixedly connected with a weaving machine body. The drying mechanism includes two brackets fixedly connected to the left side of the left side plate, and a wind pipe is fixedly connected inside the bracket. A fan is fixedly connected inside the wind pipe.

[0004] Based on the above search and combined with the existing technology, it is found that the existing lace weaving device for cloth production has certain drawbacks when in use. For example, the pressing sleeve and pressing plate need to flatten the cloth at the same time. At this time, since the opening angle of the pressing sleeve is fixed, the width of the cloth that can be flattened is fixed, and it cannot be flexibly flattened for different widths of cloth. If only the pressing sleeve is used, the flattening is not stable enough, which can easily lead to a decrease in weaving precision. Therefore, a lace weaving device for cloth production is needed.
