This apparatus structure is by feed mechanism, feeler mechanism, and transmission device, lubricating structure and organization, profiling mould is made up of interior profile mould 12, outer profile mould 11 and base plate 13, and four contour wheels 14 are operated in the imitation-shaped groove F in the profiling mould; Slubbing, two road cams, 16,15 outer rim non-involute shapes, working portion outer rim are shaped as eight road short-terms (1～8) and constitute the slope stepping of eight roads.Profiling arm 18 1 ends connect with rotating disk 7, the other end connects roller, with rotating disk 7 connection place structures be, open a stepped hole on the rotating disk 7, built-in some bearings 24, stepped appearance anchor shaft 26 passes bearing 24 endoporus and profiling arm 18 with key connecting, the other end is opened breach welding one at face and is stretched out tongue piece 29, the sagging support plate 27 of " ∪ " shape is installed in tongue piece 29 lower ends, the sagging support plate two end connecting struts 28 of " ∪ " shape, and be weldingly fixed on the rotating disk 7, constitute profiling arm sag-resistant device, promptly hold the profiling arm with sag-resistant with " ∪ " shape support.Sealed cans arm 19 is equipped with decentralizing device, and decentralizing device is made of eccentric shaft 22, and its center is fixed on the sealed cans arm 19 with a bolt 23.The profiling guide rail from bottom to top is fixed on the head spindle 32 with bolt 31, this moment, this bolt 31 passed pressing head seat 30, and profiling internal mold 12, profiling base plate 13 are fixed on the head spindle 32, and pressing head seat 30 4 limits are provided with four locatings plate 21,8 of pressure heads are installed in this locating plate, and it is convenient to change pressure head.Except that center pressure pin 33, also have another group pressure pin 34 on the holder fangs 9 at least, be arranged in holder fangs outer rim.

Its principle of work is as follows:

Shown in Figure 1, energized, motor 1 is started working, rotate by belt pulley driven gear Z1, Z2,2,3, rotate with gear Z1, Z2,2,3, ingear tooth Z3, Z4,4,5 this moment thereupon, its also rotation thereupon of bonded assembly rotating disk 7 down, be the empty wagons rotation this moment, feeler mechanism is not worked.

When the operator steps on foot-driven lever 10, make fork produce upper and lower swing by several groups of levers 35, it is upper and lower that fork drives clutch crotch 6, simultaneously, send chair bar 9 that jar is delivered to the sealed cans position, and power-transfer clutch closes, feeler mechanism work, sealed cans begin.In the sealed cans process, make sealed cans wheel 20 produce feeding, and provide correct profiling, finish sealed cans by the profiling guide rail by slubbing, two road stepping cams 16,15.Because of gear Z1, Z2,2,3 different with gear Z3, Z4,3,4 numbers of teeth, in the sealed cans process, produce differentially between clutch crotch 6 and the rotating disk 7, power-transfer clutch is separately finished the sealed cans process when rotating disk 7 rotates the N circle.

The profiling mode is direct profiling, as shown in Figure 2, is made of inside and

outside profiling mould

12,11 and base plate 13 respectively, and four contour wheels 14 are operated in the imitation-shaped groove F that is formed by inside and outside profiling mould, under the situation of high-speed operation, can reach accurate profiling.

Its feeding as shown in Figure 5, changing the arc involute feeding of former garden is stepping, and feeding roller 17 forms stepping along slope, eight roads (1～8) motion in slubbing cam 16 work areas, also is stepping when being converted to two roads and taking turns 15 feedings, so just make that the sealed cans feeding is more accurate, indeformable.

Profiling arm 18 is connected on the rotating disk 7, and shown in Fig. 3,9, some profiling arm axles hold and are fixed in the bearing carrier ring 25.Anchor shaft 26 and profiling arm 18 are connected with key, and have step to prevent upper and lower play.At its front end the sag-resistant device is installed also in addition, sees shown in Figure 6ly, hold the tongue piece 29 that is welded on the profiling arm 18 with " ∪ " shape sagging support plate 27, and be fixed on the rotating disk 7 through pillar 28, preventing profiling arm 18 work-hourses one, long it is sagging.

For guarantee to change pressure head reorientates accurately, the design is provided with four locatings plate 21 on pressing head seat 30, as shown in Figure 8, the bolt that unclamps on the pressure head 8 unloads push-down head 8, changes pressure head again and locatees according to locating plate, and is accurately, convenient.Together be fixed on the head spindle 32 with base plate 13, internal mold 12 and the pressing head seat of bolt 31 simultaneously the profiling guide rail, simple, convenient.

In the sealed cans process, the track that can seaming wheel 20 is walked has deviation, at this moment, can adjust track by the decentralizing device on the sealed cans arm 19, as shown in Figure 7, adjust the off-centre of its eccentric shaft 22 and can adjust its run trace, eccentric shaft 22 is fixed on the sealed cans arm 19 by bolt 23.

In addition, set up at least one radius stay 34 on the holder fangs, can prevent holder jar rotation, influence the sealed cans quality, see shown in Figure 10.

Compared with prior art this device has the following advantages:

1, owing to adopted direct profiling, thereby can reach high-precision profiling, and in fortune at a high speed Indeformable when turning to, the sealed cans quality is good.

2, owing to an end on the profiling arm is equipped with bearing, the other end is equipped with sagging prevention device, thereby better Guaranteed sealed cans quality, working stability.

3, because this machine adopts four can seaming wheel, two slubbing rollers, two two road rollers, thereby sealed cans speed is quick.

4, because pressing head seat is provided with four locatings plate, thereby it is convenient to change pressure head, and accurate positioning, does not need repair profiling guide rail.

5, because feeding mode is stepping, thereby profiling is more accurate, and the sealed cans quality is better.

6, owing on the sealed cans arm decentralizing device is housed, thereby can accomplishes to adjust track when sealed cans, the sealed cans quality is good.
