Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of non-woven fabric production, in particular to a high-speed lapper. BACKGROUND

[0002] Non-woven fabric is a kind of fabric formed without spinning and weaving, which is formed by orienting or randomly arranging textile short fibers or filaments into a web structure and then solidifying by mechanical, thermal or chemical methods. It is a new type of fiber product with softness, air permeability and planar structure, which is directly formed by using polymer chips, short fibers or filaments through various web forming methods and solidification technologies. Non-woven fabric has a wide range of applications, among which in medical and sanitary cloth, it is often used to make surgical gowns, protective clothing, sterilization cloth, masks, diapers, sanitary napkins and the like.

[0003] When making sanitary cloth, the fiber cotton material needs to be stacked into a multi-layer structure after being opened and formed into a single-layer cotton web in the lapper. The lapper curtain reciprocates along the left-right direction to lay the cotton web on the lower conveying curtain, and the lower conveying curtain drives the cotton web to convey forward, so that the cotton web is continuously laid and conveyed forward. However, the existing lapper has a large distance between the lapper curtain and the lower conveying curtain, and during the process of laying a layer of cotton web and moving reversely, the suspended length of the cotton web between the lapper curtain and the lower conveying curtain is large, which results in low laying precision of the left and right edges of the multi-layer cotton web. The cotton web with a wide edge needs to be cut off in the later stage, which increases the manufacturing cost. On the other hand, it also leads to an increase in lapping travel and low lapping efficiency. Therefore, it is necessary to set up a lifting mechanism to drive the lower conveying curtain to be as close as possible to the lapper curtain. If a transmission belt is used to drive the lower conveying curtain, the strength of the transmission belt is not enough due to the large overall weight of the lower conveying curtain, which is easy to break. If a chain wheel and chain combination is used to drive the lower conveying curtain, the control precision is not high due to the large distance between the chain wheel teeth. Therefore, it is necessary to make a high-speed lapper to solve the above problems. SUMMARY
