Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of textile machinery, in particular to a needle-punched cotton continuous production equipment. BACKGROUND

[0002] The needle-punched cotton is made of polyester fiber and formed through a needle punching process. The needle-punched cotton has a wide range of applications, and is used as a filling material for masks, clothes, heating sheets and home insulation. The needle-punched cotton is also known as needle-punched felt, needle-punched cotton and needle-punched non-woven fabric in the industry. It has the characteristics of high density, thin thickness and hard texture, and the weight is about 80-500 grams, the thickness is 1-8 millimeters, and various sizes can be customized according to customer requirements.

[0003] In the prior art, the production process of the needle-punched cotton needs to continuously drive the needles to reciprocate at a high speed, so that the fibers moving up and down are extruded to compress, and thus the needle-punched cotton has low resilience after needle punching. When the pressure is too large, it is not easy to reset after being pressed, so when the needle-punched cotton is cut, the corners are pressed more obviously and the tightness is different from the center, which affects the product quality. When the pressure is too small, the needle-punched cotton is a mixture of fibers, and flying fibers are easily generated during cutting, which affects the working environment. The needle-punched cotton is directly rolled and folded by manual work after cutting, and the surface smoothness and flatness of the needle-punched cotton are also affected by the pressure after cutting. In addition, the existing needle-punched cotton production process lacks a needle falling detection link, which cannot guarantee the safety of manual folding. SUMMARY
