Description

Double-sided needling device for non-woven fabric processing

Technical Field

The utility model relates to the field of non-woven fabric equipment, in particular to a double-sided needling device for processing non-woven fabrics.

Background

The manufacture process of the non-woven fabric is different from the traditional textile process, at present, in the production line of the non-woven fabric, the oriented or randomly arranged fibers are combined by the methods of friction, cohesion, bonding and the like and then are needled for reinforcement, and the principle is as follows: when the needle passes through the fiber web, the surface and partial inner layer fibers of the fiber web are forced to penetrate into the fiber web, the original fluffy fiber web is compressed due to the friction effect among the fibers, when the needles exit the web, the penetrated fiber bundles are disengaged from the barbs and remain in the web, so that a plurality of fiber bundles entangle the web and cannot return to the original fluffy state, and a substantial number of fiber bundles are penetrated into the web through a plurality of needle punching, the fibers in the web are entangled with each other, thereby completing the needling processing work of the non-woven fabric, the prior needling device for processing the non-woven fabric can only perform needling on one surface of the non-woven fabric, the mode ensures that the non-woven fabric after being needled is difficult to achieve the required strength and has poor needling quality, and current acupuncture is difficult to be dismantled, need dismantle whole needle bed during the dismantlement, wastes time and energy, for this reason, we provide a two-sided acupuncture device for non-woven fabrics processing.

SUMMERY OF THE UTILITY MODEL

In order to solve the defect that the existing needling device for processing non-woven fabrics can only carry out single-sided needling, the utility model provides a double-sided needling device for processing non-woven fabrics.

The technical scheme adopted by the utility model for solving the technical problems is as follows: a double-sided needling device for non-woven fabric processing comprises a winding wheel and a frame, wherein the winding wheel is arranged at one end of the frame, the winding wheel is connected with a motor arranged on the frame, an upper needle plate and a lower needle plate are arranged in the middle of the frame, a plurality of downward needle points are arranged at the lower part of the upper needle plate, a plurality of upward needle points are arranged at the upper part of the lower needle plate, the contact part of the needle points and the upper needle plate and the contact part of the lower needle plate are needle point bottoms, a threaded column is connected with the needle point bottoms, threaded holes matched with the threaded column are arranged on the upper needle plate and the lower needle plate, the top of the needle points is of a branched structure, an upper cylinder arranged on the frame is connected above the upper needle plate, a lower cylinder arranged on the frame is arranged below the lower needle plate, and the upper cylinder and the lower cylinder are connected with an electromagnetic valve arranged on the frame, the needle-free winding machine is characterized in that the upper needle plate and the lower needle plate are vertically corresponding in position, needle points on the lower needle plate and needle points on the upper needle plate are staggered, at least two guide wheels are vertically arranged at the other end of the machine frame at positions close to the upper needle plate and the lower needle plate, an extrusion wheel set is arranged between each guide wheel and the upper needle plate, an extrusion wheel set is arranged between each guide wheel and the lower needle plate, at least two discharging wheels are arranged at the other end of the machine frame, and the extrusion wheel set is arranged between each winding wheel and the upper needle plate.

As an improvement of the double-sided needling device for processing non-woven fabrics, two layers of fixed steel wire meshes are arranged between the upper needle plate and the lower needle plate.

As can be seen from the above, the present invention has the following advantages compared with the prior art:

the double-sided needling device for processing the non-woven fabric is reasonable in structure, the non-woven fabric surface layer and the non-woven fabric inner layer are placed on the feeding wheel and penetrate through a steel wire mesh through the guide wheel and the extrusion wheel set, the upper cylinder drives the upper needle plate to move downwards, the lower cylinder drives the lower needle plate to move upwards, the top branched structure of the needle point can forcedly penetrate fibers of the non-woven fabric surface layer into the non-woven fabric inner layer to be intertwined, the needle point is fixed in threaded holes in the upper needle plate and the lower needle plate through the threaded columns, and the winding wheel drives the non-woven fabric inner layer to move through the motor.
