Detailed Description
As shown in the figure, the ribbon machine comprises a ribbon discharging component, a ribbon positioning component, a ribbon drawing component, a ribbon folding component, a ribbon cutting component and a ribbon switching component, wherein the ribbon discharging component is used for discharging a ribbon A, and comprises a material winding and discharging barrel 1; the silk ribbon positioning component is used for positioning a silk ribbon to be discharged, the silk ribbon positioning component comprises a positioning plate 15 which is fixedly installed, a silk ribbon guide groove 16 is formed in the upper surface of the positioning plate 15, the discharging end of the silk ribbon guide groove 16 faces the silk ribbon drawing component, a silk ribbon pressing wheel 17 is arranged at the feeding end of the silk ribbon guide groove 16, and the silk ribbon pressing wheel 17 is arranged in a mode of swinging up and down; the ribbon drawing part is positioned in front of the ribbon positioning part and used for grabbing the head of the ribbon and drawing the head outwards, the ribbon drawing part comprises a drawing seat 6 and a material pressing head 5, the drawing seat 6 is pushed by a drawing cylinder 7 to move forwards and backwards, the material pressing head 5 can be movably arranged on the drawing seat 6 up and down, the material pressing head 5 is pushed by a vertical cylinder 3 to move up and down, and the vertical cylinder 3 is arranged on the drawing seat 6; the silk ribbon folding part and the silk ribbon cutting part are positioned between the silk ribbon positioning part and the silk ribbon drawing part, the silk ribbon folding part is used for folding the external silk ribbon, the silk ribbon folding part comprises a folding rod 4 with the head hung outside, the inner side end of the folding rod 4 is connected with a lifting plate, and the lifting plate is pushed by a folding motor 2 to move up and down through the transmission of a synchronous belt; the silk ribbon cutting component is used for cutting the external silk ribbon, the silk ribbon cutting component comprises a pair of scissors 13 which do cutting action, and the cutting action of the scissors 13 is pushed by a cutting cylinder 14; the silk ribbon switching part is positioned below the silk ribbon cutting part and used for transferring the silk ribbon from the cutting position to the bonding position, the silk ribbon switching part comprises a clamping jaw 11 and a clamping jaw air cylinder 12 connected with the clamping jaw 11, the clamping jaw air cylinder 12 can be rotatably arranged, and the rotation of the clamping jaw air cylinder 12 is pushed by the rotating motor 8.
The invention works as follows: after the silk ribbon A comes out of a material roll discharging barrel 1, the silk ribbon A is conveyed to a positioning plate 15 to be positioned, the silk ribbon is positioned in a silk ribbon guide groove 16, the silk ribbon is pressed by a silk ribbon pressing wheel 17, the head of the silk ribbon is exposed out of the silk ribbon guide groove 16 at the moment, a silk ribbon drawing part approaches to the positioning plate 15 at the moment, a pressing head 5 and a drawing seat 6 clamp the exposed head of the silk ribbon, the silk ribbon is drawn outwards for a certain distance after being clamped, a folding rod 4 is moved downwards, the silk ribbon is drawn downwards from the middle position of the external silk ribbon, so that the silk ribbon is folded in double layers, the silk ribbon drawing part approaches to the positioning plate 15 again after the double layers of the silk ribbon are folded in double layers, then a clamping jaw 11 of a silk ribbon switching part acts to clamp the upper part of the double layers of the silk ribbon, a scissors 13 cuts the silk ribbon from the original position of the exposed head of the silk ribbon after being clamped, and a cylinder 12 turns downwards after the actions, the clamping jaws 11 transfer the cut silk ribbon from the cutting position to the bonding position, in the bonding position, under the action of the bonding cylinder 9, the bonding pressure head 10 presses the upper end part of the cut silk ribbon on the box cover, the silk ribbon is bonded and fixed with the box cover which is coated with glue in advance, then the clamping jaws 11 release the silk ribbon, the box cover which is coated with the silk ribbon is conveyed away, and the automatic silk ribbon feeding production of the box cover product is completed by circulating the steps.
