Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by a person of ordinary skill in the art without creative work fall within the protection scope of the present application.

[0040] The core of the present application is to provide a full-automatic bag making and filling machine, which can avoid the problem of film edge curling, ensure the welding quality of the soft bag, meet the welding operation of soft bags of multiple capacities, and has good applicability.

[0041] The full-automatic bag making and filling machine provided by the present application includes a frame 15, a film feeding assembly, a bag making station 6, a front production assembly, a transfer station 11 and a rear production assembly, and integrates bag making, plug inserting and filling, please refer to Fig. 1 、 Fig. 2 .

[0042] The specific structure of the frame 15 can be set according to the size and position of the installed components, and it is only required to have sufficient strength and hardness.

[0043] The film feeding assembly is arranged on the frame 15 and is used for conveying film materials, and mainly includes an upper film station 2, a printing station 3 and a film pulling station 4 arranged in sequence according to the operation sequence. The upper film station 2 can unroll the whole roll of film materials to supply the subsequent stations. The printing station 3 can print the film materials by transferring the pigment of the color band to the surface of the film materials through a heated printing template with a certain pressure.

[0044] The film pulling station 4 pulls the printed film materials to realize the feeding of the film materials, and the pulling mode can be not limited to a suction cup, a clamping jaw or a mechanical hand.

[0045] The upper film station 2, the printing station 3 and the film pulling station 4 can be selected and used according to the prior art, which is not limited here.

[0046] The bag making station 6 is arranged on one side of the film feeding assembly, and is used for welding the periphery of the film material to form a soft bag. Specifically, the bag making station 6 comprises an upper mold and a lower mold arranged opposite to the upper mold. The upper mold is provided with a plurality of first air cylinders arranged on one side of the upper mold for driving the upper mold to move up and down. The lower mold is provided with a plurality of second air cylinders arranged on one side of the lower mold for driving the lower mold to move up and down. Through the joint action of the first air cylinders and the second air cylinders, the upper mold and the lower mold can be moved. That is, at least one of the first air cylinders and the second air cylinders moves to make the upper mold and the lower mold close to each other, so as to heat and weld the film material sent by the film drawing station 4. After the periphery of the film material is uniformly stressed, the film material is welded into a soft bag form. The soft bag form is also provided with an opening for installing a hose. After the hose and the soft bag are welded, a to-be-sealed piece 16 is formed.

[0047] As a preferred embodiment, the heating parts of the upper and lower molds are both made of aluminum alloy material, and the welding surfaces of the two molds which are in contact with the periphery of the soft bag are preferably made of steel material, so as to ensure the uniformity of heating and the welding quality of the soft bag.

Specifically, the effective welding area of the mold is increased by the arrangement position of the first air cylinders and the second air cylinders, so that the periphery of the film material is uniformly stressed, and the edge rolling phenomenon is avoided. When processing a large-capacity soft bag, the periphery of the film material is prevented from rolling by arranging a plurality of first air cylinders and a plurality of second air cylinders, so as to ensure the welding quality of the large soft bag. While meeting the processing of a single large soft bag, the processing of multiple small-capacity soft bags is also met. The number and quality of the soft bags processed in a single cycle are improved, the production speed is improved, and the cost is reduced.
