The above object of the present invention is achieved by the following technical solutions:

the utility model provides a winding location frock in preimpregnation glass roving area, includes the base, has erect the wallboard on the base, and wallboard upper portion is equipped with the convex shoulder screw rod, and convex shoulder screw rod and wallboard keep rolling the cooperation, and the lower part is equipped with the screw rod fixedly, and two clamp plate one end of vertical opposition are installed on the convex shoulder screw rod, and the other end is installed on the handle, is equipped with the stopper between wallboard and the clamp plate, and the part of treating winding preimpregnation glass roving area passes convex shoulder screw rod and handle, arranges in fixedly between two clamp plates, and by two clamp plates press from both sides tightly, install two pressure disks of opposition on the screw rod, are equipped with the stopper between wallboard and the pressure disk, and the charging tray of preimpregnation glass roving area passes the screw rod dress between two pressure disks, the clamp.

Wherein, two clamp plates are provided with lower limit grooves for fixing parts. In addition, the pressure plate close to the wall plate is detachable from the two pressure plates. The handle may be a shoulder straight handle. The wall plate is welded on the base, and in addition, the screw rod is also welded on the wall plate.

During winding, the prepreg glass roving belt of the charging tray is fixed at the upper end of the part, the handle is rotated clockwise to drive the pressing disc below to rotate anticlockwise, a certain tension force is kept, and the prepreg glass roving belt is wound on the part between the pressing plates.

The tool disclosed by the invention can ensure uniform force application and no deviation in direction by rotating and winding in the vertical direction, and the prepreg glass roving tape has uniform width and good thickness consistency in the winding process; the winding machine is simple to operate, multiple workers are prevented from walking back and forth in the winding process, and the winding machine can be operated by only one person, so that labor and winding time are saved.

Detailed Description

The winding and positioning tool for the prepreg roving tape of the invention is further explained with reference to the attached drawings.

FIG. 1 is a schematic plan view of a wound prepreg glass fiber roving tape in an example. As shown in fig. 1, the prepreg glass roving tape wound body (hereinafter referred to as a part) in the embodiment includes 2 metal bushings 10, chopped fiber fillers 11 placed between the metal bushings 10, and a prepreg glass roving tape 14 wound around the metal bushings 10 and the chopped fiber fillers 11.

Fig. 2 is a schematic view of the structure of the inventive tool in a state in which a prepreg roving tape is wound, and fig. 3 is an isometric view of the inventive tool. As shown in the figure, the winding and positioning tool for the prepreg glass roving belt comprises a base 1, wherein a wall plate 2 is erected on the base 1, and the wall plate 2 is connected with the base 1 through spot welding. The upper part of the wall plate 2 is provided with a convex shoulder screw rod 3, the convex shoulder screw rod 3 and the wall plate 2 keep rolling fit, and the lower part is fixedly provided with a screw rod 7 through spot welding. The vertically opposite left pressing plate 5 and the vertically opposite right pressing plate 6 are respectively provided with two through holes and two lower limit grooves, and the lower limit grooves are used for fixing the metal bushing and limiting the height of the metal bushing. An upper through hole of the left pressing plate 5 is used for installing the convex shoulder screw rod 3, and a limiting block 9 is arranged between the left pressing plate 5 and the convex shoulder screw rod to limit the position of the left pressing plate 5 not to change in the winding process. The lower through hole of the left pressing plate 5 is connected and fixed with the convex shoulder straight handle 4 by spot welding. 2 metal bushings 10 of the part shown in fig. 1 are placed in the lower limit grooves of the left pressure plate 5, then chopped fiber fillers 11 of the part are placed between the metal bushings 10, an upper through hole of the right pressure plate 6 penetrates through the shoulder screw rod 3, and a lower through hole penetrates through the shoulder straight handle 4 and is installed on the right side of the part.
