Description

Technical Field

[0001] This utility model relates to the technical field of heat sealing equipment, and in particular to a heat sealing device for packaging bags. Background Technology

[0002] Packaging bags are bags used to package various objects, making it convenient to transport and store goods during production and distribution. In order to ensure the airtightness of the packaging bags, a heat-sealing mechanism is needed to seal the packaging bags during the production process.

[0003] The patent titled "A Packaging Bag Heat-Sealing Device" (patent application number: 202221840377.4) discloses a packaging bag heat-sealing device, relating to the field of heat-sealing technology. It includes a support frame, with a worktable installed between the inner walls of the support frame. A first mounting plate is provided on one side of the upper end of the worktable, and a groove is formed in the first mounting plate. A second slider is slidably installed in the groove. A drive mechanism for vertical movement is provided on the other side of the upper end of the worktable. By starting a first motor, material on two first rotating shafts passes over the surface of the worktable. Starting a second motor causes the heat-sealing mechanism to move. With the movable cooperation between the second rotating shaft and the connecting plate, the heat-sealing component is always vertically downward. With the sliding cooperation between the first mounting groove and the first slider, the position of the second rotating shaft can be adjusted, thereby shortening the stroke of the heat-sealing component and increasing the movement frequency. Under the action of the drive mechanism, the heat-sealing component contacts the material surface, realizing continuous heat-sealing processing of materials of different sizes.

[0004] In the above-mentioned case, the driving mechanism enables the hot-pressing component to contact the material surface, achieving continuous hot-pressing processing of materials of different sizes. However, it is difficult to expel the air inside the packaging bag, leaving air residue in the sealed bag. Since air contains bacteria and microorganisms, this can accelerate food spoilage and shorten its shelf life. Therefore, it is necessary to propose a hot-press sealing device for packaging bags to solve these problems. Utility Model Content

[0005] The purpose of this invention is to provide a heat-sealing device for packaging bags to solve the problem mentioned in the background art that it is difficult to expel the air inside the packaging bag, resulting in residual air in the sealed packaging bag. Since bacteria and microorganisms are present in the air, it is easy to accelerate the spoilage of food and thus shorten the food storage time.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a packaging bag heat sealing device, including a base plate, a processing box fixedly connected to the top of the base plate, and an auxiliary component provided on the back of the processing box;

[0007] The auxiliary components include a connecting tube, an airbag, a fixing plate, a first electric push rod, and a second clamping plate;

[0008] The connecting pipe is fixedly connected to the inner wall of the processing box, and one end of the connecting pipe is fixedly connected to the side of the airbag. The outside of the processing box is fixedly connected to the side of the fixing plate. The inside of the fixing plate is fixedly connected to the outside of the first electric push rod. The telescopic end of the first electric push rod is fixedly connected to the outside of the second clamping plate.

[0009] Preferably, the number of airbags is two, and the two airbags are symmetrically arranged inside the processing box.

[0010] Preferably, a first clamping plate is fixedly connected to the top of the processing box, and a plurality of exhaust grooves are provided inside the second clamping plate.

[0011] Preferably, a limiting component is provided on the side of the processing box. The limiting component includes a limiting plate and a support plate. The side of the support plate is fixedly connected to the side of the processing box. The limiting plate is fixedly connected to the side of the support plate. The outside of the limiting plate is slidably connected to the inside of the side of the second clamping plate.

[0012] Preferably, a hot pressing assembly is provided on the top of the base plate. The hot pressing assembly includes a support frame, a second electric push rod, and a hot pressing block. The bottom of the support frame is fixedly connected to the top of the base plate, and the inside of the support frame is fixedly connected to the outside of the second electric push rod. The telescopic end of the second electric push rod is fixedly connected to the top of the hot pressing block.

[0013] The technical effects and advantages of this utility model are as follows:

[0014] 1. By setting auxiliary components, when performing heat sealing on the packaging bag, the packaging bag can first be placed between two air bladders, and then the air pump connected to the outside of the connecting pipe can be turned on. The air pump generates gas to inflate the air bladders. The air bladders expand due to inflation and squeeze the packaging bag, causing the air inside the packaging bag to be quickly expelled. Then, the heat sealing operation can be performed, which can reduce the air in the packaging bag and thus improve the storage time of food.

[0015] 2. When placing the packaging bag in the packaging box, the part of the packaging bag that needs to be sealed can be exposed outside the processing box. Then, open the first electric push rod. The first electric push rod will drive the second clamping plate to move towards the first clamping plate, so that the second clamping plate contacts the first clamping plate, thereby fixing and clamping the packaging bag. Since the second clamping plate has multiple venting grooves inside, the part of the packaging bag that contacts the venting grooves will not be squeezed by the second clamping plate, so that the air inside the packaging bag can be discharged from here, which facilitates the venting of the packaging bag.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] This utility model provides, for example Figures 1-3 The illustrated packaging bag heat sealing device includes a base plate 1, a processing box 2 fixedly connected to the top of the base plate 1, and an auxiliary component provided on the back of the processing box 2. The auxiliary component includes a connecting pipe 3, an airbag 4, a fixing plate 6, a first electric push rod 7, and a second clamping plate 8. The outside of the connecting pipe 3 is fixedly connected to the inner wall of the processing box 2, and one end of the connecting pipe 3 is fixedly connected to the side of the airbag 4. The outside of the processing box 2 is fixedly connected to the side of the fixing plate 6. The inside of the fixing plate 6 is fixedly connected to the outside of the first electric push rod 7. The telescopic end of the first electric push rod 7 is fixedly connected to the outside of the second clamping plate 8. There are two airbags 4, and the two airbags 4 are symmetrically arranged inside the processing box 2. When performing heat-sealing on the packaging bag, first place the packaging bag between two air bags 4, then turn on the air pump connected to the outside of the connecting pipe 3, and inflate the air bags 4 with the gas generated by the air pump. The air bags 4 expand due to inflation and squeeze the packaging bag, causing the air inside the packaging bag to be quickly expelled due to compression. Then, perform heat-sealing on it. This can reduce the air in the packaging bag, thereby improving the storage time of the food.

[0022] In addition, a first clamping plate 5 is fixedly connected to the top of the processing box 2, and multiple exhaust grooves 9 are opened inside the second clamping plate 8. A limiting component is provided on the side of the processing box 2, which includes a limiting plate 10 and a support plate 11. The side of the support plate 11 is fixedly connected to the side of the processing box 2, and the limiting plate 10 is fixedly connected to the side of the support plate 11. The outside of the limiting plate 10 is slidably connected to the inside of the side of the second clamping plate 8. The part of the packaging bag that needs to be sealed can be exposed outside the processing box 2. Then, the first electric push rod 7 is opened, which will drive the second clamping plate 8 to move towards the first clamping plate 5, so that the second clamping plate 8 contacts the first clamping plate 5, thereby fixing and clamping the packaging bag. Since multiple exhaust grooves 9 are opened inside the second clamping plate 8, the part of the packaging bag that contacts the exhaust grooves 9 will not be squeezed by the second clamping plate 8, so that the air inside the packaging bag can be discharged from here, which facilitates the venting of the packaging bag. The limiting plate 10 can limit the movement of the second clamping plate 8, thereby improving the stability of the movement of the second clamping plate 8.

[0023] Finally, a hot-pressing assembly is provided on the top of the base plate 1. The hot-pressing assembly includes a support frame 12, a second electric push rod 13, and a hot-pressing block 14. The bottom of the support frame 12 is fixedly connected to the top of the base plate 1, and the inside of the support frame 12 is fixedly connected to the outside of the second electric push rod 13. The telescopic end of the second electric push rod 13 is fixedly connected to the top of the hot-pressing block 14. After the air inside the packaging bag is discharged, the second electric push rod 13 is opened, which will drive the hot-pressing block 14 to move downward. The heating wire inside the hot-pressing block 14 will heat the hot-pressing block 14. When the hot-pressing block 14 contacts the position of the packaging bag that needs to be sealed, the packaging bag is heat-sealed.

[0024] Working principle: During the heat-sealing operation of the packaging bag, the packaging bag is first placed between two air bladders 4. Then, the air pump connected to the outside of the connecting pipe 3 is turned on. The air pump generates gas to inflate the air bladders 4. The air bladders 4 expand due to inflation and squeeze the packaging bag, causing the air inside the packaging bag to be quickly expelled. Then, the heat-sealing operation is performed, which can reduce the air in the packaging bag, thereby improving the storage time of the food. The part of the packaging bag that needs to be sealed can be exposed outside the processing box 2. Then, the first electric push rod 7 is turned on, which will drive the second clamping plate 8 to move towards the first clamping plate 5, so that the second clamping plate 8 contacts the first clamping plate 5, thereby fixing and clamping the packaging bag. Since the second clamping plate 8 has multiple exhaust grooves 9 inside, the part of the packaging bag that contacts the exhaust grooves 9 will not be squeezed by the second clamping plate 8, so that the air inside the packaging bag can be expelled from here, which facilitates the exhaust of the packaging bag. The limiting plate 10 can limit the movement of the second clamping plate 8, thereby improving the stability of the movement of the second clamping plate 8. After the air inside the packaging bag is discharged, the second electric push rod 13 is opened. The second electric push rod 13 will drive the hot pressing block 14 to move downward. The electric heating wire inside the hot pressing block 14 will heat the hot pressing block 14. When the hot pressing block 14 contacts the position of the packaging bag that needs to be sealed, the packaging bag will be heat-sealed.
