Description

Technical Field

[0001] The present invention relates to the technical field of paper bag forming, and in particular to a green and environmentally friendly packaging bag forming production device and a use method. Background Art

[0002] Packaging bags are bags used to package various items and are widely used in daily life and industrial production. Currently, most packaging bags on the market are made of plastic materials, which are not environmentally friendly. To achieve environmental protection, paper bags have begun to be widely used. However, in actual use, it has been found that when paper bags are used to hold items with high water content or when condensation accumulates on the surface of objects, the water can soak the paper bags, causing them to rupture and become unusable. To overcome this problem, existing technologies add a plastic waterproof film to the inner surface of paper bags. However, this waterproof film is bonded to the paper roll before the paper bag is formed, forming a film-coated paper roll. Furthermore, paper bag processing generates cutting waste, and the resulting scraps are a mixture of paper bag and waterproof film. Recycling requires separating the two, but the separation is costly, so many companies simply discard them, which in turn creates environmental problems for environmentally friendly paper bags. Therefore, to overcome these problems, there is a need for a green and environmentally friendly packaging bag forming and production device that facilitates the separation of the paper bag and waterproof film, as well as a method for its use.

[0016] To illustrate the technical content, achieved objectives and effects of the present invention in detail, the following description is given in conjunction with the embodiments and accompanying drawings.

[0017] Please refer to Figures 1 to 4 , a green and environmentally friendly packaging bag 5 forming production device, including a hot pressing mechanism 1 and a sleeve mechanism 2; The hot pressing mechanism 1 includes a base 11, a fan 12, a first cylinder 13, a connecting seat 14, a connecting frame 15 and a heatable hot pressing bottom plate 16 and a hot pressing top plate 17. The fan 12 includes an air suction port 121 and an air outlet 122. The hot pressing top plate 17 is arranged directly above the hot pressing bottom plate 16. The connecting seat 14 is connected to the base 11 through the connecting frame 15 and is located above the hot pressing top plate 17. The first cylinder 13 is connected to the connecting seat 14. The first cylinder 13 drives the hot pressing top plate 17 to reciprocate in the vertical direction toward the hot pressing bottom plate 16. A plurality of air suction ports 18 are respectively provided on the hot pressing bottom plate 16 and the hot pressing top plate 17. The air suction ports 18 are connected to the air suction ports 121. The space between the hot pressing bottom plate 16 and the hot pressing top plate 17 is a working space. The sleeve mechanism 2 includes a second cylinder 21, a support base 22, a first slider 23, a second slider 24, and a first suction pipe 25. The support base 22 is connected to the base 11 and includes a working surface 221. The working surface 221 is parallel to the upper surface of the hot pressing bottom plate 16. The second cylinder 21 is located directly above the working surface 221. The second cylinder 21 is connected to the bottom of the connecting base 14 and drives the first suction pipe 25 to reciprocate toward the working surface 221. The working surface 221 has an adsorption area in the middle, and the adsorption area has a plurality of suction holes 222 connected to the suction port 121; a first track 223 and a second track 224 are provided on the working surfaces 221 on both sides of the adsorption area, and the first slider 23 is located on the first track 223 and reciprocates horizontally along the first track 223 toward the workspace. An air outlet pipe 26 is provided on the side of the first slider 23 facing the adsorption area, and the air outlet pipe 26 extends above the adsorption area and then bends and extends toward the workspace; the second slider 24 is located on the second track 224 and moves along the track, and a second air suction pipe 27 is provided on the second slider 24; The first air intake pipe 25 and the second air intake pipe 27 are in communication with the air intake port 121 , and the air outlet pipe 26 is in communication with the air outlet 122 .

[0018] As can be seen from the above description, by forming the paper bag 51 and the protective film inside it separately to form an independent paper bag 51 and an independent protective film bag 52, since both can be processed and formed independently, the scraps produced are independent and can be easily recycled and reused. In addition, a similar sleeve connection is adopted, that is, the paper bag 51 is sleeved on the outside of the protective film bag 52, which is simple to process and easy to operate. The hot melt adhesive layer can ensure that the hot melt adhesive melts after hot pressing to achieve adhesion, and then the protective film bag 52 achieves a waterproof effect. In addition, the bent air outlet pipe 26 can push the protective film bag 52 while also causing the protective film bag 52 to expand due to the air flow, thereby conforming to the inner wall of the paper bag 51. The second air suction pipe 27 performs suction to ensure that the protective film bag 52 is tightly attached to the inner wall of the paper bag 51. After being withdrawn, the heatable hot pressing bottom plate 16 and the heat pressing top plate 17 are closed up and down for heating and hot pressing, ensuring the formation of the green and environmentally friendly packaging bag 5.

[0019] Furthermore, the hot pressing base plate 16 is connected to the base 11 via a buffer seat 19; The buffer seat 19 includes a plurality of springs, which are evenly distributed between the base 11 and the lower surface of the hot pressing bottom plate 16 .

[0020] As can be seen from the above description, the multiple springs can reduce the impact generated when the hot pressing top plate 17 moves downward, thereby ensuring the service life of the equipment.

[0021] Furthermore, a workbench 3 is provided below the base 11 , an operating surface 31 is provided on the workbench 3 , and double-button linkage switches 32 are provided on the left and right sides of the operating surface 31 , and the double-button linkage switches 32 control the operation of the first cylinder 13 .

[0022] From the above description, it can be seen that the double-button linkage switch 32, that is, the two buttons are pressed at the same time to enable the green environmentally friendly packaging bag 5 molding production device to perform hot pressing work (the hot pressing top plate 17 moves downward), reducing the probability of accidents.

[0023] Furthermore, an emergency stop button 33 is provided on the operating surface 31 .

[0024] It can be seen from the above description that the emergency stop button 33 can facilitate the emergency stop of the equipment.

[0025] Furthermore, the hot pressing mechanism 1 further includes a connecting arm 141 and a vertical track 142, wherein the vertical track 142 is vertically arranged on the connecting seat 14, and the connecting seat 14 is provided with a through hole for the connecting arm 141 to pass through; The first cylinder 13 is connected to the hot pressing top plate 17 via a connecting arm 141; The connecting arm 141 is slidably connected to the vertical track 142 and runs along the vertical track 142 .

[0026] It can be seen from the above description that the arrangement of the vertical rail 142 and the connecting arm 141 can facilitate the accuracy of the operation of the hot pressing top plate 17 driven by the first cylinder 13 .

[0027] Furthermore, electric heaters 4 are respectively provided in the hot pressing bottom plate 16 and the hot pressing top plate 17 .

[0028] It can be seen from the above description that the heating effect can be achieved by setting the electric heater 4.

[0029] A method for using the above-mentioned green and environmentally friendly packaging bag 5 forming production device includes: Obtain a formed paper bag 51 with an opening and a bag-shaped protective film bag 52 with an opening; the protective film bag 52 has a hot melt adhesive layer on its outer surface; The paper bag 51 is placed on the workspace, with the opening of the paper bag 51 facing the work surface 221. The first cylinder 13 moves downward and activates the fan 12. The suction port 18 sucks the upper and lower sides of the paper bag 51. The first cylinder 13 moves upward to open the opening of the paper bag 51. The second slide 24 moves toward the workspace to insert the second suction pipe 27 into the opening of the paper bag 51. Move the first slider 23 away from the working space; place the protective film bag 52 on the working surface 221, and point the opening of the protective film bag 52 toward the side away from the working space; after the second cylinder 21 descends, the first suction pipe 25 and the suction hole 222 simultaneously suck the protective film bag 52, and then the second cylinder 21 ascends to open the opening of the protective film bag 52; while the first slider 23 moves toward the working space, the air outlet pipe 26 is inserted into the opening of the protective film bag 52 and pushes the protective film bag 52 into the opening of the paper bag 51, and at the same time, the second air intake pipe 27 starts to continuously inhale, and the air outlet pipe 26 uses air pressure to make the protective film bag 52 fit the inner wall of the paper bag 51, and then the second suction pipe 27 and the air outlet pipe 26 are slowly pulled out; after being pulled out, the first cylinder 13 descends and heats and presses to melt the hot melt adhesive layer to achieve bonding to obtain a green and environmentally friendly packaging bag 5.

[0030] Furthermore, after hot pressing, the air outlet pipe 26 continuously discharges air to blow off the green environmentally friendly packaging bag 5 that has been hot pressed.

[0031] As can be seen from the above description, the green environmentally friendly packaging bag 5 that has been heat-pressed is blown off by continuously exhausting air through the exhaust pipe 26, which can conveniently free up the working space for the next work.

[0032] Furthermore, after hot pressing, the air intakes 18 on the hot pressing bottom plate 16 and the hot pressing top plate 17 stop working.
