It should be noted that the embodiments of the utility model and the features in the embodiments can be combined with each other without conflict.

[0017] It should be understood that these descriptions are exemplary only and are not intended to limit the scope of the present invention.

[0018] Some embodiments of the present invention are described below in conjunction with the accompanying drawings.

[0019] Reference Figure 1, an efficient packaging four-side sealing production line, comprising a folding station, a bottom sealing station, a double lower heat sealing station, a material placing station, a double upper heat sealing station, a top sealing station, an easy-tear hole punching station and a cutting station arranged in sequence, wherein the folding station folds the strip film along the center line of the length direction into a V-shaped belt with an upper opening (the strip film can be made of a highly sealable composite material OPP19+JVMPET12+PE50 as a raw material), and the hot pressing head of the bottom sealing station hot presses the lower end of the V-shaped belt The bottom seal 1 is formed, the temperature of the hot pressure head of the bottom seal station is 140°C, the hot pressure heads of the double lower heat sealing stations heat press the lower part of the V-shaped belt to form two lower side seals 2 arranged vertically, the temperature of the hot pressure heads of the double lower heat sealing stations is 148°C, the lower ends of the lower side seals 2 overlap with the two ends of the bottom seal 1, forming a plurality of arranged lower closed semi-enclosed bag bodies, the material placing station adds material into the semi-enclosed bag body, and the hot pressure heads of the double upper heat sealing stations heat press the semi-enclosed bag body. An upper side seal 3 is formed on the upper side of the bag body, the temperature of the hot pressure head of the double upper side heat sealing station is 150°C, the lower end of the upper side seal 3 coincides with the upper end of the lower side seal 2, the hot pressure head of the top sealing station heat presses the top of the semi-closed bag body to form an edge-closed sealed bag, the temperature of the hot pressure head of the top sealing station is 146°C, the easy-tear opening punching station cuts out an easy-tear opening 5 for tearing at the edge of the sealed bag, the cutting station cuts in the middle of the edge seals on the left and right sides of the sealed bag along the up and down directions to form an independent sealed bag, and the bottom, the lower ends on both sides, the upper ends on both sides, and the top of the V-shaped belt are heat-sealed in turn to form an edge-closed sealed bag, and there are overlapping heat-sealed parts between each heat-sealing process, which can effectively ensure the sealing effect of the sealed bag, and at the same time, a material placing station is added between the heat sealing of the lower ends on both sides and the upper ends on both sides of the V-shaped belt. When placing materials, the opening size of the semi-closed bag body can be increased, which is more convenient for material placement. The entire production process has a high degree of automation, and the production is fast and efficient.

[0020] The height of the lower side seal 2 is 1 / 2-2 / 3 of the height of the V-shaped belt to ensure the depth of the semi-enclosed bag body and avoid the overflow of the material due to the small internal volume of the semi-enclosed bag body after the material is placed. When placing the material, it is first necessary to place it through the cloth (i.e. the wet wipes themselves) and then inject the additive liquid, such as water.

[0021] The material placing station includes a feeder, a placing table, an additive liquid injection assembly and an insertion rod controlled by a cylinder. The placing table is located directly above the semi-enclosed bag body and is provided with an insertion hole. When the semi-enclosed bag body is transported to the placing table, the semi-enclosed bag body is aligned with the insertion hole. The feeder feeds dry cloth onto the placing table. The cloth is symmetrically placed along the insertion hole. The insertion rod controlled by the cylinder is then inserted into the insertion hole. At the same time, the dry cloth is folded in half and inserted into the semi-enclosed bag body. Finally, the additive liquid injection assembly injects additive liquid into the semi-enclosed bag body.

[0022] The upper end of the upper side seal 3 is flush with the top of the semi-closed bag body.

[0023] The hot pressing head of the top sealing station hot presses the top of the semi-enclosed bag body to form a top seal 4 , and both ends of the top seal 4 overlap with the upper ends of the upper side seal 3 respectively.

[0024] Embodiment 1: The cutting station is a tear line cutting station, and the tear line cutting station cuts tear lines 6 in the middle of the edge seals on the left and right sides of the sealed bag along the up and down direction.

[0025] Embodiment 2: The cutting station is a slitting station, and the slitting station cuts in the middle of the edge seals on the left and right sides of the sealed bag along the up and down direction to form a plurality of independent sealed bags.

[0026] The heat sealing width of the double lower heat sealing station and the double upper heat sealing station is twice that of the bottom sealing station and the top sealing station, that is, half of the edge seals hot-pressed by the double lower heat sealing station and the double upper heat sealing station belong to one of the two adjacent sealed bags, and the other half belongs to the other of the two adjacent sealed bags. After processing at the easy-tear line cutting station or the slitting station, the edge seal widths on the four sides of an independent sealed bag are consistent.

[0027] The feeding end of the material placing station is provided with a guide part for opening the top opening of the semi-closed bag body. When the semi-closed bag body is transported to the material placing station, the two sides of the top of the semi-closed bag body are opened by the guide part, thereby increasing the opening size of the semi-closed bag body, making it more convenient for the insertion rod to insert the cloth into the semi-closed bag body and inject the additive liquid into the semi-closed bag body.

[0028] The outer side of the sealed bag is located inside the edge seal and is printed with text information.
