Description

Single pole capping device

Technical field

The utility model is mainly concerned with a kind of single pole capping device, is widely used in the capping of rolling of various bottle classes in medicine and food machinery.

Background technology

Single pole capping device commonly used at present is generally by gland component, the lipper parts, bottle supporting member, transmission device, wiper cam, thumb wheel is formed, bottle cap has been enclosed within on the bottleneck before the work, thumb wheel is together with bottle, bottle cap is sent into the pressure head bottom of the gland component of rotation, bottle stand in the bottle holder, bottle supporting member is up, bottle is pressed between pressure head and the bottle supporting member together with bottle cap, bottle cap is glanded the pressure head of parts and catches rotation, bottle also passive rotation on the bottle pallet behind the friction drag that overcomes between bottle and the bottle holder, the lipper parts are under the control of wiper cam, rely on the pressure head below rapidly, lipper rolls the joint portion to bottle cap skirt section and bottleneck, with both tightly roll compacting be one, the lipper parts break away from gland component and get back to original position under the control of wiper cam, at the same time, and the descending return of bottle supporting member, relative two cams are finished in their motions.Its advantage is that structure is simpler, and its weak point is when the friction force between each bottle cap of bottle is big inadequately, rolls the quality instability of lid, and bottle rises easily to fall to cover.

The utility model content

The technical problems to be solved in the utility model just is: at the technical matters that prior art exists, the utility model provide a kind of simple and compact for structure, operate steadily reliable, roll and cover the measured single pole capping device of matter.

For solving the problems of the technologies described above, the solution that the utility model proposes is, a kind of single pole capping device, it comprises gland component, lipper parts, bottle supporting member, transmission device, lifter cam, wiper cam and thumb wheel, it is characterized in that: described lifter cam is contained on central axle sleeve or the frame, gland component and lifter cam contact matching, be fixed with shift fork on the gland component, be fixed with ring on the described lipper parts, shift fork is sleeved in the ring, and bottle supporting member and gland component be rotation synchronously under the driving of transmission device.

Be fixed with back-up ring on the lipper axle on the described lipper parts, between the toothed disc of back-up ring and lipper parts, stage clip arranged.

Compared with prior art, advantage of the present utility model just is:

1, single pole capping device of the present utility model have simple and compact for structure, operate steadily reliable, roll and cover advantages such as quality is good, after the utility model device rolls lid, the female surface of the joint portion of lower end, bottle cap skirt section and bottleneck is smooth, smooth, attractive in appearance, combine between bottleneck and the bottle cap closely, the quality of rolling lid is good, and stable and reliable for performance, rational in infrastructure;

2, bottle supporting member and gland component rotate under the driving of transmission device synchronously in the single pole capping device of the present utility model, and wiper cam control lipper accurately rolls lid.The characteristics of the technical program are to change in the prior art that simple gland component rotates to be gland component and bottle supporting member rotates synchronously, and the stressed synchronous rotation simultaneously of bottle and bottle cap does not have the phenomenon that bottle does not change; Simultaneously, changing bottle supporting member buck bottle is that gland component and lipper parts synchronization lifting are pressed bottle, favourable conformability and the accuracy of covering the position of rolling.

The specific embodiment

Below with reference to the drawings and specific embodiments the utility model is described in further details.

As shown in Figure 1, a kind of single pole capping device of the present utility model, it comprises gland component 1, lipper parts 2, bottle supporting member 3, transmission device 4, lifter cam 5, wiper cam 6, thumb wheel 16 is formed, lifter cam 5 is fixed on central axle sleeve or the frame, gland component 1 through roller shaft and roller and lifter cam 5 in the cam path contact matching, gland component 1 is fixed with shift fork 7, be fixed with ring 8 on the lipper parts 2, shift fork 7 is sleeved in the ring 8, gland component 1 drives under the control of lifter cam 5 with lipper parts 2 and rises or descend, and gland component 1 is ceaselessly rotation under the driving of transmission device 4; Lipper parts 2 through be fixed on the lipper axle top link 12 and on roller shaft, roller and be fixed on central axle sleeve or frame equally on wiper cam 6 cooperate, drive and control the lipper 14 in the following swing arm 13 that is contained in the lipper lower end, near or leave gland component 1, bottle supporting member 3 rotates synchronously with gland component 1 under the driving of transmission device 4.

May there be the gap in cooperation between shift fork 7 and the ring 8, below the ring 8 of the lipper axle of lipper parts 2, can also fix a back-up ring 9, the adjustable positions of back-up ring 9 on it, on the lipper axle between back-up ring 9 and the toothed disc 10, stage clip 11 is arranged, when lipper parts 2 downlink working, stage clip upwards has individual top power, the shift fork of fixing on the gland component 17 is the benchmark faying face with the lower plane of ring 8, guarantee that lipper 14 is constant with the relative position of pressure head 15 at work, be that lipper 14 remains unchanged with the bottle cap axial distance, roll and cover uniformity.Can also fix a back-up ring 9 on the lipper axle of lipper parts 2, on the lipper axle between the toothed disc 10 of back-up ring 9 and lipper parts 2 stage clip 11 be arranged, it is in the below of ring 8, in order to eliminate possible gap between ring 8 and the shift fork 7.

Principle of work: bottle cap and bottle bottle cap before entering this device has overlapped on bottleneck, when thumb wheel 16 is sent into bottle cap one pressure head 15 belows of gland component 1 of rotation, also bottle is sent in the bottle holder of bottle supporting member 3, gland component 1 is descending under the control of lifter cam 5, and bottle cap and bottle are pressed between gland component 1 and the bottle supporting member 3 together.The gland component 1 that bottle and bottle cap drive with transmission device 4, bottle supporting member 3 one rotation synchronously, pressure head 15 is caught bottle cap, lipper parts 2 are descending with gland component 1 under with the restriction of ring 8 at aforementioned shift fork 7, and under the control of wiper cam 6, lipper 14 on it rolls the joint portion to bottle and bottle cap, with both tightly roll compacting be integral, in this process, lipper 14 contrarotation under the drive of bottle cap rotational resistance, roll the lid finish after, lipper parts 2 under the control of wiper cam 6 outside pendulum leave bottle cap, and up with gland component 1, finish an overall process of rolling lid.Because bottle cap and bottle are in the process medium speed equilibrium of gland, can not produce the phenomenon that bottle does not change, the center of bottle cap and bottle coexists on the same axis of gland component 1 bottle supporting member 3, can eliminate beat separately between bottle cap and the bottle fully, bottle cap and bottle be stressed uniformity in rolling the process of lid, its result must be that the female surface of the joint portion in lower end, bottle cap skirt section and the bottle is smooth, smooth, attractive in appearance, combining fully between bottleneck and the bottle cap seals, and the utility model rolls that to cover quality good and stable and reliable for performance, rational in infrastructure.

The above only is a preferred implementation of the present utility model, and protection domain of the present utility model also not only is confined to the foregoing description, and all technical schemes that belongs under the utility model thinking all belong to protection domain of the present utility model.Should be pointed out that for those skilled in the art in the some improvements and modifications that do not break away under the utility model principle prerequisite, these improvements and modifications also should be considered as protection domain of the present utility model.
