Description

Technical Field

[0001] The present application relates to the field of textile materials, and more specifically, it relates to a preparation process and product of a felt belt for a vibrating knife cutting machine. Background Art

[0002] The felt belt plays a role of soft conveying during high-speed conveying, protecting the conveyed objects from scratches during conveying. It has good conductivity, softness and surface cut resistance. It can eliminate static electricity generated by the conveyed objects during high-speed conveying, and at the same time allows the conveyed objects to be cut stably, improving the conveying and cutting stability of the objects.

[0003] Felt tape is made by opening, combing and laying short fibers into a fiber net, then passing the fiber net through a needle to make a non-woven fabric, then using a dipping agent to dip the non-woven fabric, and finally grinding it. Since the non-woven fabric made by needle punching has a certain density, it is easy to have uneven dipping during the dipping process, resulting in uneven strength distribution of the made felt tape.

[0004] When the felt belt is used in the conveyor belt of the vibrating knife cutting machine, since the vibrating knife cutting machine continuously generates high-frequency vibration through the vibrating knife, heat and pressure are generated on the surface of the conveyed material to cut the conveyed material. Therefore, the felt belt is prone to local deformation or even breakage during long-term vibrating use, which reduces the practicality of the felt belt. Summary of the invention

[0005] In order to solve the problem that the felt belt used in the vibrating knife cutting machine is prone to local deformation or even breakage after long-term use, the present application provides a preparation process and product of the felt belt for the vibrating knife cutting machine.

[0006] In a first aspect, the present application provides a process for preparing a felt belt for a vibrating knife cutting machine, using the following technical solution:

[0007] A process for preparing a felt belt for a vibrating knife cutting machine comprises the following steps:

[0008] S1, laying short fibers on the surface of nylon mesh cloth, and needle punching to obtain needle punched cloth;

[0009] S2, soaking the needle-punched cloth with a soaking liquid to obtain a pretreated needle-punched cloth;

[0010] S3, using a dipping agent to perform dipping treatment on the pretreated needle-punched cloth, shaping, and drying to obtain a dipping needle-punched cloth;

[0011] S4, grinding and cutting the obtained impregnated non-woven fabric to obtain a felt belt.

[0012] By adopting the above technical scheme, the nylon mesh cloth has good strength, wear resistance and air permeability. Through the needle-punching process, the flat short fibers are needle-punched on the nylon mesh cloth to prepare a needle-punched cloth with good softness and density, so as to improve the strength of the prepared felt belt; since the needle-punched cloth has a certain density, direct dipping will affect the uniformity and efficiency of dipping, so the needle-punched cloth is first soaked with a soaking liquid, and the soaking liquid penetrates and disperses into the interior of the needle-punched cloth. Under the action of the soaking liquid, the dense fiber structure of the needle-punched cloth is fully stretched, the looseness of the dense fiber structure and the gap between the dense fiber structure are improved, so as to prepare a pretreated needle-punched cloth. The pretreated needle-punched cloth is then dipped in glue, and the dipping agent fully infiltrates and penetrates into the fiber gaps of the pretreated needle-punched cloth, with good dipping uniformity, to prepare a dipped needle-punched cloth with good flexibility and mechanical properties; then, through shaping, the dipping agent is further infiltrated and preliminarily solidified; finally, the dipped needle-punched cloth is sanded so that the surface of the dipped needle-punched cloth has a uniform plush texture, thereby preparing a felt belt with good flexibility, mechanical properties and wear resistance. The felt belt is used in a vibrating knife cutting machine, has good tensile strength and wear resistance, is not prone to local deformation or breakage, and has good practicality.

[0013] Preferably, the short fibers are one or a combination of polyester fibers, polypropylene fibers, viscose fibers, and polyamide fibers.

[0027] Preferably, the dipping rate in step S3 is 2-4 m / min, and the dipping temperature is 20-45°C.

[0028] By adopting the above technical scheme, the better impregnation conditions can make the impregnation agent fully penetrate the pretreated needle-punched cloth; at the same time, it can also have better processing efficiency, so that the pretreated needle-punched cloth can be fully impregnated in a shorter processing time, saving production time.

[0029] Preferably, the impregnation agent in step S3 is prepared from the following raw materials in weight percentage:

[0040] Preferably, the dispersant is composed of a double-terminal hydroxyl polyether modified silicone oil and an aminosilane coupling agent in a weight ratio of 1:(0.2-0.6).

[0041] By adopting the above technical scheme, the double-terminal hydroxyl polyether modified silicone oil is composed of polyether segments and silicon segments, has good wetting and dispersion stability, and can produce good synergistic effects with aminosilane coupling agents. The impregnating agent prepared in this way can stably and fully impregnate the pretreated needle-punched cloth, and the felt belt prepared in this way has good impregnation rate and mechanical properties.

[0121] Performance testing
