Description

Technical Field

[0001] The invention relates to the technical field of glue spraying equipment, in particular to glue spraying equipment for chemical fiber cotton and a glue spraying method thereof. Background Art

[0002] ‌Chemical fiber cotton equipment‌ is mainly used to produce chemical fiber cotton, which is a non-woven fabric material commonly used in making cotton clothes, space suits, quilts and sleeping bags, etc.

[0003] The chemical fiber cotton equipment sprays adhesive on the fluffy fiber layer, and after drying and curing, forms a porous and highly fluffy structure, thereby providing good warmth retention effect. Therefore, the chemical fiber cotton produced by the chemical fiber cotton equipment has good resistance to dry and wet washing and is suitable for a variety of washing environments. The material is light, soft and comfortable, and is suitable for various warm products.

[0004] The operating process of the chemical fiber cotton equipment is to first loosen and comb the fibers, loosen and comb the natural cotton fibers, man-made fibers or synthetic fibers to form a fluffy fiber layer, and then evenly spray the adhesive on both sides of the fiber layer to ensure that the adhesive can penetrate into the fiber layer. Finally, the fiber layer sprayed with the adhesive is dried and cured to bond the intersections between the fibers while maintaining the freedom of the fibers.

[0005] However, in the most critical glue spraying process of existing chemical fiber cotton, since the glue spraying distribution area is circular, in order to fully spray the side area of ​​the cotton layer, the nozzle must pass over the top of the cotton layer until it reaches the outside of the cotton layer, which causes waste. If some glue is not wasted, the glue sprayed on the side of the cotton layer will be less than that in the middle of the cotton layer, resulting in a dilemma between ensuring quality and avoiding waste. Summary of the invention

[0014] The glue spraying method of the glue spraying equipment, using the glue spraying equipment of chemical fiber cotton, comprises the following steps: S1: The glue spraying conveying system drives the glue spraying system to move horizontally; S2: Movement of transporting chemical fiber cotton on the chemical fiber cotton transport system; S3: The glue spraying deflection system changes the jet shape of the jet nozzle to guide the glue.

[0023] The present invention will be further described below in conjunction with the accompanying drawings: like Figure 1 — Figure 6As shown, the present embodiment provides a glue spraying device for chemical fiber cotton, including a glue spraying frame 1, a glue spraying conveying system 2, a glue spraying system 3, a chemical fiber cotton conveying system 4 and a plurality of glue spraying deflection systems 5, the glue spraying conveying system 2 is installed on the glue spraying frame 1, the glue spraying system 3 is slidably installed on the glue spraying frame 1, the glue spraying system 3 is used for transverse movement on the glue spraying frame 1, so as to achieve uniform spraying of the cotton layer, the glue spraying conveying system 2 is transmission-connected with the glue spraying system 3, so as to achieve the transverse movement of the glue spraying system 3, the chemical fiber cotton conveying system 4 is installed on the glue spraying frame 1, so as to achieve the conveying of the cotton layer, the chemical fiber cotton conveying system 4 is located at the lower side of the glue spraying system 3, the glue spraying system 3 sprays glue onto the cotton layer on the chemical fiber cotton conveying system 4, the glue spraying system 3 has a plurality of glue spraying ports 321, and each glue spraying deflection system 5 includes a glue spraying deflection device 51 and a glue spraying jet device 52, the glue spraying jet device 52 forms a jet port on the outer side of each glue spraying port 321, and the jet port of the glue spraying jet device 52 is flexible, which is convenient for implementation The glue spraying deflection device 51 is rotatably installed on the glue spraying system 3, and the glue spraying deflection device 51 is transmission-connected with the jet nozzle. The jet nozzle realizes deformation during the rotation of the glue spraying deflection device 51. In order to achieve the effect of strengthening the glue spraying on the side of the cotton layer, when the jet nozzle and the glue spraying port 321 follow the glue spraying system 3 to move to the side of the cotton layer, the glue spraying deflection device 51 rotates, so that the jet nozzle becomes wider in the direction close to the side of the cotton layer, and then before the glue spraying system 3 reaches the side of the cotton layer, more glue is guided to spray to the side of the cotton layer, thereby ensuring uniform spraying, and being able to evenly spray the cotton layer to avoid glue waste. On the other hand, the jet nozzle constrains the trajectory of the glue spraying, and constrains the circular area originally sprayed from the glue spraying port 321 to be close to a triangle (the triangle is the best as described in detail below), and makes the triangular spraying area fit with the side of the cotton layer, thereby preventing the glue spraying system 3 from needing to exceed the side of the cotton layer to spray the entire cotton layer completely. Waste caused.

[0024] In order to explain the restrictive effect of the deformation of the jet nozzle on the airflow from the perspective of geometric relationship, please note that after the glue spray deflection device 51 mentioned above rotates, the jet nozzle becomes wider in the direction close to the side of the cotton layer. From the basic knowledge of geometry, it is known that when the glue spray deflection device 51 rotates, the upper end of the glue spray jet device 52 will remain unchanged (disclosed as a circle below), and because the lower end of the glue spray jet device 52 is deformed and the jet nozzle becomes wider in the direction close to the side of the cotton layer, it is bound to cause the side of the cotton layer of the jet nozzle to tilt toward the inside of the cotton layer (see Figure 5 ), so that the airflow from the air jet outlet is deflected inwards, preventing the sprayed glue from spraying outside the cotton layer.

[0025] Specifically, the glue spraying conveying system 2 includes a glue spraying conveying motor 21 and a glue spraying conveying belt 22. The glue spraying conveying belt 22 is a synchronous belt. The glue spraying conveying motor 21 is installed on the glue spraying machine frame 1. The glue spraying conveying belt 22 is wound around the output end of the glue spraying conveying motor 21.

The glue spraying conveying block 31 can be slidably installed on the glue spraying machine rack 1 through a sliding pair. The sliding pair is a conventional dovetail groove sliding pair or uses a commercially available guide rail slider structure to achieve sliding, which will not be repeated here, thereby achieving reciprocating lateral movement on the glue spraying machine rack 1.
