Description

Flexible tubbiness film folding mechanism

Technical Field

The utility model relates to a flexible tubbiness film folding mechanism.

Background

There are many mechanisms for forming a film into a barrel shape on the market at present, and a mechanism for folding a flat film alone is also found, but a mechanism for folding a film formed into a barrel shape again is not found.

The traditional film generally forms a barrel shape through a forming machine, wraps a product and achieves the purpose of packaging, and when the film which is folded to form the barrel shape is wrapped, the film is manually folded, so that the folding mechanism in the prior art is difficult to realize high-efficiency and high-quality film folding work due to the characteristics of small thickness, high softness, low plasticity and the like of the film, and the production requirements cannot be met in the actual production process.

SUMMERY OF THE UTILITY MODEL

The utility model discloses a solve one of above-mentioned technical problem, the technical scheme who adopts is: the utility model provides a flexible tubbiness film folding mechanism, is including locating drive shaft and the tight axle that rises in the frame, and the one end of drive shaft links to each other with power input device, is equipped with two driving sprocket in the drive shaft, is equipped with two tight pulleys that rise in the tight epaxial that rises, links to each other through a chain between two sets of driving sprocket and the tight pulley that rises respectively, is equipped with the roller group between two chains, and the roller group includes a plurality of roller, and the round pin epaxial in two chains is installed respectively at the both ends of roller.

Preferably, there are two of said turning roll sets.

Preferably, the chain transmission device further comprises two transition chain wheels which are matched with the two chains respectively.

Preferably, the power input means comprises a power input sprocket provided on the drive shaft.

Preferably, the chain support plate device further comprises two chain support plates arranged on the rack, the two chain support plates are arranged corresponding to the two chains, the middle parts of the chains are supported, and the chains are prevented from collapsing.

The beneficial effects of the utility model are embodied in:

1. this mechanism is used for folding tray bottom film rear end of cutting down, the drive sprocket drive chain motion of this mechanism, the roller group is along with the chain motion, the tray is by the in-process that conveying mechanism transported forward, the film bottom is touched to the roller group, because the speed of roller is higher than the speed that the tray was carried, the film is withstood to the roller front end, make the film fold the tray bottom, this mechanism can realize the film folding work of present unable automatic realization, it is folding to replace the manual work, the labor cost is reduced, and the production efficiency is improved.

Throughout the drawings, like elements or components are generally identified by like reference numerals. In the drawings, elements or components are not necessarily drawn to scale.

Fig. 1 is a schematic structural diagram of the present invention.

In the figure, 1, a drive shaft; 2. a tensioning shaft; 3. a drive sprocket; 4. a tension wheel; 5. a chain; 6. a turning roll group; 7. a transition sprocket; 8. and a chain supporting plate.

Detailed Description

Embodiments of the present invention will be described in detail below with reference to the accompanying drawings. The following examples are only for illustrating the technical solutions of the present invention more clearly, and therefore are only examples, and the protection scope of the present invention is not limited thereby.

As shown in fig. 1, a flexible barrel-shaped film folding mechanism includes a driving shaft 1 and a tension shaft 2, which are disposed on a frame (not shown in the figure), one end of the driving shaft 1 is connected to a power input device, two driving sprockets 3 are disposed on the driving shaft 1, two tension wheels 4 are disposed on the tension shaft 2, two groups of driving sprockets 3 and the tension wheels 4 are connected to each other through a chain 5, a roller set 6 is disposed between the two chains 5, the roller set 6 includes a plurality of rollers, and two ends of each roller are mounted on a pin of the two chains 5.

The utility model discloses the mechanism is a work unit on the tray film packaging product line, and power input device drives drive shaft 1 rotatory, and drive shaft 1 drives two drive sprocket 3 rotations to realize the motion of two chains 5, the running roller group 6 is along with 5 cyclic motion of chain. After the tray film rear end is cut, the film rear end is bent to the tray below by wind-force, and the tray can be carried extremely by conveying mechanism the utility model discloses folding mechanism, the tray is by the in-process that conveying mechanism transported forward, and the film bottom is touched to the roller set 6, because the speed of changeing the roller is higher than the speed that the tray was carried, changes the roller front end and withstands the film, makes the film fold the tray bottom.

Preferably, the number of the roller sets 6 is two, and if two roller sets 6 are selected, the rotating speed of the driving wheel 1 can be reduced a little, and two roller sets 6 are preferably arranged in view of cost saving.

Preferably, two transition sprockets 7 are included, which cooperate with the two chains 5, respectively.

Preferably, the power input means comprises a power input sprocket provided on the drive shaft 1.

Preferably, the chain support device further comprises two chain support plates 8 arranged on the rack, wherein the two chain support plates 8 are arranged corresponding to the positions of the two chains 5, support the middle parts of the chains 5 and prevent the chains 5 from collapsing.

The above embodiments are only used to illustrate the technical solution of the present invention, and not to limit the same; although the present invention has been described in detail with reference to the foregoing embodiments, it should be understood by those skilled in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some or all of the technical features may be equivalently replaced; such modifications and substitutions do not substantially depart from the scope of the embodiments of the present invention, and are intended to be covered by the claims and the specification; to those skilled in the art, any alternative improvements or changes made to the embodiments of the present invention are all within the scope of the present invention.
