Technical Field

The utility model belongs to the technical field of medical dressing, in particular to a coiling mechanism for water thorn machine.

Background

The spunlace nonwoven fabric is formed by jetting high-pressure micro water flow onto one or more layers of fiber webs to enable the fibers to be mutually entangled, so that the fiber webs are reinforced and have certain strength, and the obtained fabric is the spunlace nonwoven fabric. The fiber raw materials are widely available, and can be terylene, chinlon, polypropylene fiber, viscose fiber, chitin fiber, superfine fiber, tencel, silk, bamboo fiber, wood pulp fiber, alginate fiber and the like. The production of spunlaced nonwoven fabrics is usually carried out by a spunlace machine, which usually comprises a plurality of spunlace heads, an unwinding device, a winding device, and the like. Wherein, coiling mechanism includes along the frame that sets up to the front and back (can with unwinding device, sharing such as water thorn head), along the front and back to locating the non-woven fabrics at frame top carry the curtain (locate the rear of water thorn head) and carry a set of rolling structure etc. of curtain rear end rear side below, rolling structure includes along controlling to locating the rolling axle in the frame, the articulated two pendulum rods of the frame left and right sides, along controlling to locating the compressing roller between two pendulum rods and drive compressing roller compress tightly the last non-woven fabrics of rolling axle compress tightly the die cylinder etc. of compressing roller, be equipped with the rolling support that is used for supporting the rolling axle in the frame or subaerial, rolling support left side or right side are along controlling to being equipped with the rotatory coiling motor of drive.

When an existing all-cotton spunlace non-woven fabric is produced in a spunlace workshop, a grey fabric roll needs to be changed when reaching a certain roll diameter, a traditional spunlace winding mode is that a motor drives a winding shaft to rotate to roll the grey fabric, the winding motor needs to be stopped (and a spunlace machine stops) when the roll is changed, the connection between the winding shaft and a universal joint of the winding motor is manually separated, the winding shaft is taken down, a new winding shaft is replaced, and finally the spunlace machine and the winding motor are started.
