Description

Technical Field

[0001] The utility model relates to the technical field of sealing machines, in particular to an exhaust structure for a high-temperature edge pressing sealing machine. Background Art

[0002] A sealing machine is a machine that seals containers filled with packaging materials. After the product is loaded into the packaging container, the packaging container needs to be sealed to preserve the product, maintain product quality, and avoid product loss. Existing sealing machines mostly seal the packaging bags by high-temperature pressing. When sealing, the original air in the packaging bag easily causes the packaging bag to bulge, which not only takes up space during transportation, but also is easily squeezed and burst.

[0003] For this reason, we design an exhaust structure for a high-temperature edge sealing machine. Utility Model Content

[0012] Compared with the prior art, the utility model provides an exhaust structure for a high-temperature edge pressing and sealing machine, which has the following beneficial effects:

DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] See also Figure 1-Figure 4 In this embodiment: an exhaust structure for a high-temperature edge pressing sealing machine comprises a bottom plate 1, wherein the bottom plate 1 is fixedly mounted on the sealing machine, and the installation position of the structure on the sealing machine is located in front of the hot pressing strip of the sealing machine, and an inverted first U-shaped frame 2, a lower clamping plate 3 and an upright second U-shaped frame 8 are installed on the bottom plate 1, the lower clamping plate 3 is located on the inner side of the first U-shaped frame 2, an upper clamping plate 4 is arranged above the lower clamping plate 3, a U-shaped handle 7 is rotatably mounted on the top of the upper clamping plate 4, and two sliding clamps are installed on the top of the first U-shaped frame 2 A symmetrical slide bar 5, the bottom end of the slide bar 5 is fixed to the top of the upper clamping plate 4, and a first spring 6 is sleeved on the slide bar 5. The first spring 6 is located between the first U-shaped frame 2 and the upper clamping plate 4. The first spring 6 is always in a compressed state. In the absence of external force to pull the upper clamping plate 4 upward, the upper clamping plate 4 will always be pressed on the lower clamping plate 3 by the elastic force of the first spring 6. The upper and lower clamping plates can cooperate to clamp the bag opening of the packaging bag. The length of the upper and lower clamping plates and the length of the first U-shaped frame 2 can be appropriately lengthened or shortened according to actual conditions.

[0022] See also Figure 4 The second U-shaped frame 8 is located in front of the lower clamping plate 3, and an exhaust pipe 9 is rotatably installed on the second U-shaped frame 8. The front end of the exhaust pipe 9 is connected to an air pump 10 through a hose, and the air pump 10 is installed on the sealing machine. A gear lever 13 is installed between the two side plates of the second U-shaped frame 8, and the gear lever 13 is located below the exhaust pipe 9. The exhaust pipe 9 can rotate on the second U-shaped frame 8. After the exhaust pipe 9 rotates to lift its rear end up to a certain angle, the bottom of the front half of the exhaust pipe 9 will abut against the gear lever 13, thereby limiting the exhaust pipe 9 from continuing to rotate. A second spring 14 is installed between the lower cross plate of the second U-shaped frame 8 and the bottom of the front end of the exhaust pipe 9. The second spring 14 is always in a stretched state. In the absence of external force pressing down the rear half of the exhaust pipe 9, the exhaust pipe 9 will always abut against the gear lever 13 under the elastic force of the second spring 14, and the elastic force of the second spring 14 is much smaller than that of the first spring 6.

[0023] See also Figure 2 The top of the lower clamp plate 3 and the bottom of the upper clamp plate 4 are both provided with grooves, and the shape and size of the combination of the two grooves are the same as the shape and size of the outer circle of the cross-section of the exhaust pipe 9. The exhaust pipe 9 can be clamped between the grooves by the upper and lower clamp plates. A layer of rubber pad 11 is installed on the top of the lower clamp plate 3 and the bottom of the upper clamp plate 4. Before using this structure for exhaust, the bag opening of the packaging bag should be placed between the upper and lower clamp plates, and the exhaust pipe 9 should be placed in the bag opening of the packaging bag. The rubber pad 11 can play a sealing role.

[0024] See also Figure 3, two grooves are provided on the front side of the upper horizontal slope of the first U-shaped frame 2, and the two side panels of the U-shaped handle 7 can be inserted into the grooves on the upper horizontal slope, and a pair of limit blocks 12 are symmetrically installed on the inner sides of the two side panels of the U-shaped handle 7. Pull the U-shaped handle 7 upward, and then insert the two side panels of the U-shaped handle 7 into the grooves on the first U-shaped frame 2, so that the limit blocks 12 are against the top of the upper horizontal slope of the first U-shaped frame 2, so that the upper splint 4 can be separated from the lower splint 3.

[0025] The working principle and use process of the utility model are as follows: when the high-temperature edge pressing and sealing machine is used with an exhaust structure, the U-shaped handle 7 is pulled upward, and the side plates of the U-shaped handle 7 are inserted into the grooves on the first U-shaped frame 2 to separate the upper and lower clamps. The exhaust pipe 9 is lifted upward at the rear end under the elastic force of the second spring 14, and the bag opening of the packaging bag to be sealed is placed between the upper and lower clamps. At the same time, the exhaust pipe 9 is placed in the bag opening of the packaging bag, and the side plates of the U-shaped handle 7 are pulled out from the grooves on the first U-shaped frame 2. The U-shaped handle 7 is slowly loosened so that the upper and lower clamps clamp the bag opening of the packaging bag and the exhaust pipe 9, and then the air pump 10 is started to exhaust the air in the packaging bag. After the exhaust is completed, the hot pressing mechanism of the sealing machine is started to perform hot pressing and sealing on the bag opening of the packaging bag. After the sealing of the packaging bag is completed, the upper clamp 4 is pulled up to take out the packaging bag.

[0026] Finally, it should be noted that the above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. Although the utility model is described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions recorded in the above embodiments or replace some of the technical features therein by equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
