Description
Technical Field
The application relates to the field of textile materials, in particular to a preparation process and a product of a felt belt for a vibrating knife cutting machine.
Background
The felt belt has the function of soft conveying in the high-speed conveying process, protects conveyed objects from scratch in the conveying process, has good conductivity, softness and surface cutting resistance, can eliminate static electricity generated by the conveyed objects in the high-speed conveying process, ensures that the conveyed objects are stably cut, and improves the conveying and cutting stability of the objects.
The felt belt is prepared by opening, carding and spreading short fibers into a fiber web, then preparing the fiber web into non-woven fabrics through a needle, then dipping the non-woven fabrics by using a gum dipping agent, and finally carrying out sanding treatment. Because the non-woven fabric manufactured by needling has certain compactness, the non-uniform impregnation condition easily occurs in the impregnation process, so that the manufactured felt belt has the non-uniform intensity distribution.
When the felt belt is applied to the conveyer belt of the vibrating knife cutting machine, the vibrating knife cutting machine continuously generates vibrating high frequency through the vibrating knife, and heat and pressure are generated on the surface of a conveyed object so as to cut the conveyed object, so that the felt belt is easy to locally deform or even break in the long-term vibrating use process, and the practicability of the felt belt is reduced.
Disclosure of Invention
In order to solve the problem that the felt belt is easy to deform locally or even break after long-term use when being applied to a vibrating cutter, the application provides a preparation process and a product of the felt belt for the vibrating cutter.
In a first aspect, the application provides a manufacturing process of a felt belt for a vibrating knife cutting machine, which adopts the following technical scheme:
a process for preparing a felt belt for a vibrating knife cutter, comprising the steps of:
s1, spreading short fibers on the surface of a nylon sandwich mesh cloth, and performing needling to obtain needled cloth;
S2, soaking the needled cloth by using a soaking solution to prepare pretreated needled cloth;
S3, dipping the pretreated needled cloth by using a gum dipping agent, shaping and drying to obtain the gum dipping needled cloth;
S4, sanding and cutting the prepared impregnated non-woven fabric to obtain the felt belt.
According to the technical scheme, the nylon sandwich mesh cloth has good strength, wear resistance and air permeability, flat short fibers are needled on the nylon sandwich mesh cloth through a needling process to prepare the pre-treated needled cloth, softness and compactness are good, the needled cloth is soaked in the needled cloth, the needled cloth is directly soaked in the needled cloth, the uniformity and efficiency of the soaked cloth are affected, the needled cloth is soaked in a soaking liquid, the soaking liquid is permeated and dispersed into the needled cloth, the compact fiber structure of the needled cloth is fully unfolded under the action of the soaking liquid, the looseness of the compact fiber structure and gaps of the compact fiber structure are improved, the pre-treated needled cloth is soaked in the fiber gaps of the pre-treated needled cloth, the impregnated agent is fully soaked in and permeated into the needled cloth, the impregnated needled cloth is good in uniformity, the impregnated cloth is prepared, the impregnated cloth is good in flexibility and mechanical property, the impregnated cloth is further soaked in the soaking cloth, the impregnated cloth is further soaked in the soaking liquid, the impregnated cloth is enabled to be soaked in the soaking cloth, the impregnated cloth is further soaked in the soaking cloth, the impregnated cloth is enabled to be easy to be broken, the felt is not to have the wear resistance and mechanical property, the wool cloth is easy to be cut, and the wool felt is not broken, and the wool felt is prone to have the surface to be deformed, and has good mechanical property, and the wool felt is easy to be broken, and good to be broken, and the felt is good to have good mechanical property, and good wear resistance is good, and good wear resistance, and good performance and good wear resistance.
Preferably, the short fibers are one or a combination of polyester fibers, polypropylene fibers, viscose fibers and polyamide fibers.
By adopting the technical scheme, the fiber has better strength, flexibility and wear resistance, is applied to the felt belt, and can improve the comprehensive mechanical properties of the felt belt.
Preferably, the soaking temperature in the step S2 is 40-60 ℃ and the soaking time is 10-20min.
By adopting the technical scheme, the fiber of the needled cloth can be fully stretched under the better soaking condition, and the subsequent gum dipping efficiency and gum dipping uniformity are improved.
