Detailed Description
In an embodiment 1 of a hair tensioning device, in fig. 1, 2, 3 and 4, five tensioning heads 1 are provided, the tensioning heads 1 are strip-shaped sheet bodies, long holes are formed in the tensioning heads 1, and the weight of the tensioning heads can be reduced through the long holes. The front end of the tensioning head 1 is provided with an arc-shaped tensioning surface 2, the front end is one end, the front end is optionally selected before definition, and the front end is determined after definition. The arc Zhang Jinmian is a concave arc, that is, one surface of the strip-shaped sheet is an arc-shaped surface. The arc Zhang Jinmian is tangential to the two faces of the tensioning head 1, and at the tangential position, an arc fillet 3 is formed, and two sharp corners are removed due to the arc fillet, so that the hair can be prevented from being cut off by mistake. The net sheet can be prevented from being scratched, and the net sheet is safe for workers. The tensioning heads 1 are of identical construction and are arranged parallel to one another, and the tensioning heads 1 are arranged along a straight line, which means that the tensioning heads are arranged in a straight line, not one at the same place, i.e. the straight line along which they are arranged is parallel to the arcuate tensioning surfaces. The construction of each tensioning head 1 is identical and the front edges of each tensioning head are coplanar, i.e. the tensioning heads are aligned so that only the front one is seen from a certain direction and the rear is blocked, so that the arcs Zhang Jinmian are coplanar. The angle between the extending direction of each tensioning head 1 and the plane of the front edge of each tensioning head is 30 degrees. I.e. the individual tensioning heads are arranged obliquely. The rear ends of the tensioning heads 1 are connected to a strip-shaped plate 4, the strip-shaped plate 4 and the piston rod heads of the air cylinders 5 are fixed on the strip-shaped plate 4, and the piston rods are connected with the strip-shaped plate 4 through a frame 6. The cylinder 5 is a linear actuator which can push the tensioning heads to move forward, and the pushing movement direction of the cylinder is consistent with the front-back extending direction of each tensioning head 1. The cylinder body of the air cylinder 5 is square and is provided with two piston rods which are respectively fixed at two ends of the strip-shaped plate, so that the driving force can be balanced, and the movement is stable.
The tensioning head in this embodiment arranges on a straight line, can be applicable to many hairlines to for hairline tensioning in same straight line position, save operating space, avoid interfering with other parts more easily, be favorable to reducing the size of whole equipment. If a small range of deviations from a straight line is selected, the solution is degraded.
