Thermocompression bonding and unwinding mechanism for processing long-fiber non-woven fabric

Abstract

The invention relates to the technical field of non-woven fabric equipment, and discloses a thermocompression bonding and unwinding mechanism for processing a long-fiber non-woven fabric. The thermocompression bonding and unwinding mechanism comprises a mounting base; the top end of the mounting base is fixedly connected with a first mounting frame and a second mounting frame; a first shaft sleeve is mounted at the top end of the first mounting frame, and a second shaft sleeve is mounted at the top end of the second mounting frame; a rotating cylinder is rotatably connected to the inner walls of the first shaft sleeve and the second shaft sleeve; a transmission disc is fixedly connected to one end of the rotating cylinder; a servo motor is arranged on one side of the top end of the mounting base; a driving disc is fixedly connected to an output end of the servo motor; and a transmission belt is arranged between the driving disc and the side wall of the transmission disc. According to the thermocompression bonding and unwinding mechanism for processing the long-fiber non-woven fabric provided by the invention, it is guaranteed that no hot-pressing dead angle exists on the non-woven fabric on a cloth roller, the non-woven fabric can be evenly subjected to hot-pressing treatment, and the situation that lines on the end face of the non-woven fabric on the cloth roller are loose can be avoided in the high-speed rotating and hot-pressing state of the cloth roller.

Description

technical field [0001] The invention relates to the technical field of non-woven fabric equipment, in particular to a long-fiber non-woven fabric processing heat-pressing and unwinding mechanism. Background technique [0002] Non-woven fabrics, also known as non-woven fabrics, are composed of oriented or random fibers. It is called cloth because of its appearance and certain properties. Non-woven fabrics have the characteristics of moisture-proof, breathable, flexible, light weight, non-combustible, easy to decompose, non-toxic and non-irritating, rich in color, low in price, and recyclable. For example, polypropylene (pp material) pellets are mostly used as raw materials, which are produced by continuous one-step process of high-temperature melting, spinning, laying, and hot-pressing coiling. [0003] In the production process, in order to obtain a higher surface smoothness, fibers or ultra-fine fibers with a finer denier (indicated by D, indicating the weight of the wire...

Problems solved by technology

[0005] Aiming at the deficiencies in the prior art, the present invention provides a long-fiber non-woven fabric processing heat-compression unwinding mechanism, and there are certain defects in the installation process of the non-woven fabric roll by using the unwinding mechanism. When the hot-pressing operation is performed after the roller is installed, since the non-woven fabric on the cloth roller can only be hot-pressed within a certain range, the non-woven fabric on the cloth roller cannot be hot-pressed, resulting in uneven hot-pressing of the non-woven fabric Even, the cloth quality of the non-woven fabric is relatively low, which affects the quality of the non-woven fabric production. The thread on the end surface of the non-woven fabric on the cloth roller is loose, which makes the treatment effect of the non-woven fabric in the hot-pressed state not good, and reduces the processing efficiency of the non-woven fabric under the action of the cloth roller.
