The specific embodiment

Below with reference to accompanying drawings to doing detailed description according to the flexible rolling capping device of the hilted broadsword of the utility model embodiment.

Fig. 1 schematically shows the front view according to the capping device of the utility model embodiment.Fig. 2 shows capping device among Fig. 1 along the cutaway view of A-A direction.Fig. 3 shows capping device among Fig. 1 along the cutaway view of B-B direction.In conjunction with Fig. 1-3 as can be seen, this capping device comprises: support 8; Ram shaft 9 is rotatably installed on the support 8 and with respect to support 8 and can moves up and down along the arrow E direction; Pressure head 15, be installed on ram shaft 9, this pressure head is used to press the bottle cap 18 of the bottle 19 that is arranged on the bottle supporting seat 20, wherein, bottle supporting seat 20 is used for limiting moving down of they when pressure head 15 compresses bottle cap 18 and bottle 19, to guarantee that pressure head 15 can provide enough big pressure to bottle cap, wherein, this bottle supporting seat can center on the rotational of ram shaft or be maintained fixed motionless; Pole 4 can move up and down with ram shaft 9; Lipper 2 is fixed on the lipper seat 1, and first end of lipper seat 1 is connected in pole 4 rotationally by support plate 3, so that lipper 2 rolls tight described bottle cap, preferably, lipper seat 1 is fixed in support plate 3, and this support plate 3 is articulated in pole 4 by hinge 16.

In this embodiment, pole 4 is passed an end of dog seat 11 movably, and this dog seat is located on the ram shaft 9 and by jam nut 12 by bearing carrier ring and locatees along the axis direction of ram shaft 9.Thus, dog seat 11 only moves up and down synchronously with ram shaft 9, and can not rotate.The other end of dog seat 11 is provided with U-lag 111 (as shown in Figure 3), and an end of guide rod 14 passes this U-lag, and the other end is fixed on the support 8.

Preferably, this capping device also comprises slide bar 10, slide bar 10 passes support 8 by an end and can move up and down along the arrow E direction with respect to support 8, and the other end of slide bar 10 is connected with an end of connecting rod 6 by hinge 13, and the other end of connecting rod 6 is connected in second end of lipper seat by hinge 17.Thus, when slide bar 10 moves down, lipper seat 1 is rotated, around hinge 16 so that lipper 2 is adjacent to the roll extrusion position (corresponding to the closing in position of bottle 19) of bottle cap 18 and rolls tight bottle cap.Particularly, as shown in Figure 2, be provided with spring 5 between dog seat 11 and the lipper seat 1.One end of spring 5 is connected in dog seat 11 by adjustable hook 7, and the other end of spring 5 is fixed on the lipper seat 1.Hook 7 passes dog seat 11, and is connected on the dog seat by nut.Can regulating spring power size by setting nut.When slide bar 10 moved down, connecting rod 6 also moved down, and moved down thereby drive the lipper seat, and spring 5 tensions and the lipper seat is made pulling force in order to make progress drive lipper seat and lipper and rotate around hinge 16.

Preferably, the part between dog seat 11 and lipper seat 1 of pole 4 is provided with boss 41, with moving up of restriction pole 4.

Below with reference to the use of Fig. 4-8 description according to the capping device of the utility model embodiment.Fig. 4-8 shows capping device shown in Figure 1 and is in the scheme drawing that rolls each stage of the process of lid.In Fig. 4,, make slide bar 10 and ram shaft 9 be moved upwards up to the extreme higher position by the operation capping device, thereby make pressure head 15 and lipper 2 also be moved upwards up to the extreme higher position, as shown in Figure 4, at this moment, the top bottle 19 that has placed bottle cap 18 is put into the center of bottle supporting seat 20.Then, slide bar 10 and ram shaft 9 move down, and make pressure head 15 by on the bottle cap 18 that is pressed in bottle 19, and as shown in Figure 5, at this moment, when slide bar 10 moved down, connecting rod 6 also moved down, and move down thereby drive lipper seat 1.Since ram shaft 9 when moving down also around rotational, therefore, when pressure head 15 is pressed on the bottle cap 18,, also can drive bottle cap 18 and bottle 19 by the friction force that mating surfaces produced of pressure head 15 and bottle cap 18 around rotational even bottle supporting seat 20 maintains static.Then, slide bar 10 continues to move down, driving lipper seat 1 moves down, because pole 4 can move down with respect to dog seat 11, therefore hinge 16 moves down thereupon, thereby is arranged at the spring 5 stressed lipper seats 1 that upwards draw on the spring hook 7, makes lipper seat 1 rotate around hinge 16, lipper 2 contacts the roll extrusion position (this roll extrusion position is corresponding to the closing in position of bottle 19) of bottle cap 18 gradually, as shown in Figure 6.By regulating the nut of hook 7, the roll extrusion power that can regulate 2 pairs of bottle caps 18 of lipper makes the roll extrusion position of lipper 2 near bottle cap 18, as shown in Figure 7.Along with the rotation of bottle cap 18, lipper as shown in Figure 8, is finished the sealing operation of bottle cap with the inside roll extrusion in roll extrusion position of the bottle cap 18 closing in position to bottle 19.Subsequently, earlier slide bar 10 is moved up,, again pressure head 15 is upwards lifted the reference position of getting back to as shown in Figure 4, to carry out the next round operation so that lipper 2 withdraws from the position of rolling when covering.

According to capping device of the present utility model, because lipper seat 1 is connected in pole 4 rotationally, so lipper 2 can rotate around hinge 16; And because pole 4 can move up and down, thereby lipper 2 also can move up and down with respect to bottle cap, even thereby there are manufacturing errors in bottle or bottle cap, perhaps the closing in position of bottle changes, and also can make lipper be adjacent to the closing in position roll extrusion bottle cap of bottle, protects the excellent sealing effect of bottle cap, in addition, in the roll extrusion process of 2 pairs of bottle caps 18 of lipper, can regulate by 5 pairs of roll extrusion power of the spring size that is arranged between dog seat 11 and the lipper seat 1, realize flexible roll extrusion thus.

Although describe embodiment of the present utility model with reference to the accompanying drawings, but should be appreciated that, under the situation that does not break away from scope and spirit of the present utility model, those skilled in the relevant art can make variations and modifications, and all changes and modification all are intended to be comprised by claims.
