Embodiment Construction

[0017] Referring to the accompanying drawings, reflecting a specific structure of the present invention, a dynamic storage mechanism is provided between the film roll 1 and the feed roller group 7 of the bag making machine, and the dynamic storage mechanism includes a storage roller group ; The storage roller group includes the upper guide roller 3 and the upper guide roller 6 at a high position, and the lower guide roller 9 at a low position is arranged between the two upper guide rollers.

[0018] The film 2 drawn out from the film roll 1 bypasses the upper and lower guide rollers in a V-shaped distribution. The rotating shafts 13 at both ends of the two upper guide rollers are installed on the two ends of the cross arm 5, the middle part of the cross arm 5 is fixed on the lifting outer base 4 of the column 10, and the rotating shafts 8 at both ends of the lower guiding roller 9 are installed on the column. 10 on the inner base 15 of the lift.

[0019] The column 10 is prov...

Abstract

The invention discloses a dynamic storage and unwinding device for a bag making machine. A dynamic storage mechanism composed of a storage roller group is arranged between a film roll and the feedingroller group. A film drawn from the film roll is wound around upper and lower guide rollers to be distributed in a V shape; the upper and lower guide rollers are installed on lifting inner and outer bases of a stand column; and the lifting inner and outer bases are connected with one side of a chain of a sprocket and chain transmission mechanism, and when the chain does rotational motion, the moving directions of the lifting inner and outer bases are opposite. The device realizes non-stop replacing and receiving of the bag making machine, the production efficiency is improved, the bag making quality is ensured, and the dynamic storage and unwinding device is simple, reliable, easy to maintain and compact.

Description

technical field [0001] The invention relates to an automatic bag-making machine for packaging bags, in particular to an unwinding mechanism. Background technique [0002] The bag making machine is an automatic device for making plastic packaging bags of various sizes, thicknesses and specifications. When the bag making machine is working, the film roll as the raw material for bag making is located at the head end of the equipment, under the traction of the equipment. The film roll unwinds and the film enters the equipment feed roller group for processing. After the film unwinding of the current film roll is completed, it is necessary to manually replace the new film roll (called refueling), and to connect the film tail end of the current film roll and the film head end of the new film roll with adhesive tape (called splicing). material). [0003] In the prior art, in order to complete the above-mentioned work of refueling and receiving materials, the equipment must be shu...
