Description

Continuous feeding mechanism of film

Technical Field

The utility model relates to a film conveying mechanism especially relates to a continuous feeding mechanism of film.

Background

In the field of file bag production equipment and the like, a pinch roll is generally adopted to carry out stepping pinch on a film, when the film stops moving, the processes of heat sealing, gold stamping, jet printing, labeling and the like are carried out on the film, the stepping pinch control is complex, the working efficiency is low, and the stepping pinch is rarely adopted at present.

In order to carry out the processes of heat sealing, gold stamping, jet printing, labeling and the like in the continuous conveying process of the film, a synchronous moving mode is generally adopted at present, namely, the movement of processing equipment for heat sealing, gold stamping, jet printing, labeling and the like is the same as the conveying direction and the conveying speed of the film, so that the processing equipment for heat sealing, gold stamping, jet printing, labeling and the like and the film are in a relatively static state, corresponding processing actions can be carried out on the film, the mode enables the production process to be smoother, and the production efficiency is improved.

However, the above-mentioned synchronous moving method has the following disadvantages:

(1) precise synchronization is difficult to achieve, under the asynchronous condition, the processing equipment and the film move relatively, the processing quality is reduced, errors can be accumulated continuously, and when the errors exceed an allowable range, the machine needs to be stopped for re-correction;

(2) the whole processing equipment moves synchronously, so that the energy consumption is high;

(3) the processing equipment needs to move up and down, move horizontally and the like, and needs to be externally connected with a power supply and an air source, so that the complexity of an external structure of the processing equipment is greatly increased.

Disclosure of Invention

The to-be-solved technical problem of the utility model is to provide a film feeding mechanism in succession, this kind of film feeding mechanism in succession simple structure, the film that can make the front and back continuous transport is in static state in the centre, and it is fairly convenient to carry out various processing actions to reduce the energy consumption by a wide margin. The technical scheme is as follows:

a film continuous feeding mechanism is characterized in that: the device comprises a rack, a front fixed roller, a rear fixed roller, a swing frame, a swing mechanism capable of driving the swing frame to reciprocate back and forth, a front swing roller and a rear swing roller; the front fixed roller and the rear fixed roller are arranged on the rack side by side in tandem; the swing mechanism is arranged on the frame, and the swing frame is arranged on the power output end of the swing mechanism; the front swing roller and the rear swing roller are arranged on the swing frame in tandem, and are positioned on one side of the plane where the front fixed roller and the rear fixed roller are positioned; and on the projection of the plane where the front swing roller and the rear swing roller are located, the front fixed roller and the rear fixed roller are located between the front swing roller and the rear swing roller.

As a preferred scheme of the utility model, the swing mechanism comprises a swing motor, a screw rod, a nut and a guide rail; the swing motor, the screw rod and the guide rail are all installed on the rack, the screw rod is arranged in parallel with the guide rail, the screw rod is in transmission connection with the swing motor, the nut is sleeved on the screw rod, and the swing frame is installed on the guide rail and connected with the nut.

The foregoing front and back definitions are: in the film transport direction, the first arrival is before and the slow arrival is after.

Compared with the prior art, the utility model, have following advantage:

the continuous film feeding mechanism has the advantages that the front swing roller and the rear swing roller move back and forth along the front and rear directions, when the moving directions of the front swing roller and the rear swing roller are opposite to the film conveying direction, the distance between the front swing roller and the front fixed roller is lengthened to store materials, the distance between the rear swing roller and the rear fixed roller is shortened to release the films, so that the films between the front swing roller and the rear swing roller are in a static state, the processes of heat sealing, gold stamping, jet printing, labeling and the like are quite convenient, processing equipment such as heat sealing, gold stamping, jet printing, labeling and the like does not need to be moved, the energy consumption is greatly reduced, and the external connection structure of the processing equipment such as the heat sealing, the gold stamping, the jet printing, the labeling and the like is greatly simplified.

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

Detailed Description

The following further describes the preferred embodiments of the present invention with reference to the accompanying drawings.

As shown in fig. 1, the film continuous feeding mechanism comprises a frame 1, a front fixed roller 2, a rear fixed roller 3, a swing frame 4, a swing mechanism 5 capable of driving the swing frame 4 to reciprocate back and forth, a front swing roller 6 and a rear swing roller 7; the front fixed roller 2 and the rear fixed roller 3 are arranged on the frame 1 side by side in tandem; the swing mechanism 5 is arranged on the frame 1, and the swing frame 4 is arranged on the power output end of the swing mechanism 5; the front swing roller 6 and the rear swing roller 7 are arranged on the swing frame 4 in tandem, and the front swing roller 6 and the rear swing roller 7 are both positioned above the front fixed roller 2 and the rear fixed roller 3 (the front swing roller 6 and the rear swing roller 7 are both positioned on one side of the plane where the front fixed roller 2 and the rear fixed roller 3 are positioned); in the projection of the plane where the front swing roller 6 and the rear swing roller 7 are located, the front fixed roller 2 and the rear fixed roller 3 are located between the front swing roller 6 and the rear swing roller 7, that is, the front swing roller 6 is located in front of the front fixed roller 2, and the rear swing roller 7 is located behind the rear fixed roller 3.

The swing mechanism 5 comprises a swing motor 501, a screw rod 502, a nut 503 and a guide rail 504; the swing motor 501, the screw rod 502 and the guide rail 504 are all installed on the rack 1, the screw rod 502 is arranged in parallel with the guide rail 504, the screw rod 502 is in transmission connection with the swing motor 501, the nut 503 is sleeved on the screw rod 502, the swing frame 4 is installed on the guide rail 504 and is connected with the nut 503, and the nut 503 is used as a power output end of the swing mechanism 5.
