The utility model is described in further detail below in conjunction with (accompanying drawing) embodiment: in Fig. 1, by base 30, pillar stiffener 31 and two reinforcing props 32,33 constitute supporting integral body, a sliding sleeve 6 moving up and down is slidingly installed on pillar stiffener 31, end at sliding sleeve 6 is equipped with a motor 1, motor 1 clutch end connects with worm screw 35 1 ends on being fixedly mounted on sliding sleeve 6 with belt 34, the other end of worm screw 35 links with belt 48 and the fastening belt pulley 50 that is installed on the Connection Block 20, worm screw 35 be fixedly mounted on worm gear 36 on the sliding sleeve 6 formation worm gear pair that links, shown in Figure 2, on the other end of sliding sleeve 6 by axle 49 fastening a connecting seat 20 that are equipped with, connect installation one support 19 at Connection Block 20 lower end concentrics, in support 19 circle be positioned at Connection Block 20 lower ends and with it the concentric place one cover mould 21 is installed, on base 30, be equipped with one with Connection Block 20 concentrics and the plane pallet 17 vertical with this axle center, on the axle 37 of tray 17, a synchronous spring 18 is housed, move down also and can reset to realize that pallet 17 compresses under external force, stretch out at worm-wheel shaft 38 and adorn a before driving cam 3 and a rear drive cam 39 that staggers certain angle on the two end axles of two side of sliding sleeve 6 respectively, and before on these worm-wheel shaft 38 projecting shafts, adorning one respectively before piston crank mechanism 2 and the rear crank connecting rod mechanism 40, rear crank connecting rod mechanism 2,40 the other end respectively be anchored on two reinforcing props 32, adjustable arm 42 hinge connection on 33, adjustable arm 41 can be along reinforcing prop 32,33 move up and down and locate, before the bilateral symmetry position is cut with scissors connection installation one respectively on sliding sleeve 6, back lever 4,51, and should contact with before driving cam 3 by preceding lever 4 one ends, and the other end and front cam post 9 hinge connection, these back lever 51 1 ends contact with rear drive cam 39, and the other end and back cam post 29 hinge connection, back cam post 29 slip caps are loaded on the Connection Block 20, and front cam post 9 slides shell-like on the cam post 29 of back, the groove of front cam post 9 lower ends is mutually opposed with the fastening front cam 10 that is installed on the front cam arm 11, one end of front cam arm 11 and front wheel arm 13 hinge connection, and fastening connection of an end of the other end and front wheel arm 13, at front cam arm 11 middle parts one spring 12 is installed and this spring contacts with front wheel arm 13, front wheel arm 13 and Connection Block 20 hinge connection, and, front wheel 16 is installed on the front wheel seat 15 at the lower end of front wheel arm 13 ball coupling one front wheel seat 15; In like manner, the groove of back cam post 29 lower ends is mutually opposed with the fastening back cam 43 that is installed on the cam arm 42 of back, one end of back cam arm 42 and rear roller arm 44 hinge connection, and fastening connection of an end of the other end and rear roller arm 44, at cam arm 42 middle parts, back one spring 45 is installed and this spring contacts with rear roller arm 44, rear roller arm 44 and Connection Block 20 hinge connection, and, rear roller 47 is installed on the rear roller seat 46 at rear roller arm 44 lower end ball couplings one rear roller seat 46.So promptly constitute the designed device for can sealing of the utility model.The utility model principle of work is as follows: starter motor 1, motor 1 clutch end drives worm screw 35 by belt 34 and rotates, worm screw 35 drives worm gear 36 and rotates, the other end of worm screw 35 drives Connection Block 20 rotations by belt 48 simultaneously, thereby whole capping head is rotated, worm gear 36 rotates, drive installation in worm-wheel shaft 38 stretch out two ends before, rear crank connecting rod 2,40 rotate, because before, rear crank connecting rod 2,40 the other end respectively be anchored on two reinforcing props 32, adjustable arm 41 hinge connection on 33, thereby it is preceding, rear crank connecting rod 2,40 rotating drive sliding sleeve 6 is done up and down along pillar stiffener 31, and complete machine moves, according to the difference of jar height, height that can be by adjusting adjustable arm 41 is to adapt to the variation of height; During sealed cans, jar is placed on the pallet 17, current, rear crank connecting rod mechanism 2,40 motions, a capping complete machine is displaced downwardly to cover mould 21 to be contacted with jar, cover mould 21 is compressed to extreme lower position by jar with the synchronisation spring 18 on the axle 37 of supporting tray 17 immediately, at this moment, be loaded on worm-wheel shaft 38 external parts before, rear drive cam 3,39 work successively, at first, lever 4 before before driving cam 3 jack-up, preceding like this lever 4 and front cam post 9 hinge connection ends move down and hand over back, promotion front cam post 9 edge cam post 29 to move down, the front cam 10 that the groove of front cam post 9 lower ends moves down and promote to be anchored on the front cam arm 11 turns an angle along the hinge connection point of front cam arm 11 with front wheel arm 13, impetus by 12 pairs of front wheel arms 13 of spring of being installed on it when front cam arm 11 rotates makes front wheel arm 13 turn an angle along the hinge connection point of this arm and seated 20, and it is parallel near jars and realize the roll extrusion first time that the rotation of front wheel arm 13 makes the front wheel seat 15 of ball coupling in these roller arm 13 lower ends drive front wheels 16; Secondly, because before, rear drive cam 3,39 stagger mutually certain angle, after above-mentioned before driving cam 3 work and realizing the roll extrusion of certain distance, and then lever 51 after rear drive cam 39 jack-up, equally, back lever 51 moves down and promotes back cam post 29 with back cam post 29 hinge connection ends and moves down along Connection Block 20, the back cam 43 that the groove of back cam post 29 lower ends moves down and promote to be anchored on the cam arm 42 of back turns an angle along the hinge connection point of back cam arm 42 with rear roller arm 44, impetus by 45 pairs of rear roller arms 44 of spring of being installed on it when back cam arm 42 rotates makes rear roller arm 44 put along the hinge connection of this arm and Connection Block 20 and turns an angle, it is parallel near jar and realization roll extrusion for the second time that the rotation of rear roller arm 44 makes the rear roller seat 46 of ball coupling in these roller arm 44 lower ends drive rear roller 47, the above-mentioned first time, for the second time the roll extrusion deadline all cover mould 21 contact with jar to the pallet 17 spools 37 on synchronisation spring 18 be compressed to nadir and move on the capping head then, move in the time of ending when resetting to vertex on the synchronisation spring 18 and finish, synchronisation spring 18 promote pallets 17 reset with sliding sleeve 6 on move synchronously, carry out with speed, so just guaranteed the roll extrusion capping time twice.When being used to seal the bigger jar of system diameter, two front wheel and rear rollers that structure is identical can be installed, respectively on the capping head to avoid the unbalance vibration in the roll extrusion process.

The utility model has following advantage compared to existing technology:

Because adopt toggle that whole realization of capping head moved up and down automatically, thereby need not ride the picking-up jar and can carry out jar capping (end), like this, machine construction is simpler, and is easy and simple to handle, high efficiency.
