42 21 FIG.1I
The present application relates to the technical field of packaging equipments, and in particular to a vacuum sealing machine.
The vacuum sealing machine is generally used to extract air in a packaging bag into which food are usually put, and seal the packaging bag after a predetermined vacuum degree is reached, eliminating part of the air in the packaging container during a sealing process can effectively prevent the food from spoiling.
In the existing vacuum sealing machine, sealing strips are fixed in the upper cover and the lower cover. When the upper and lower covers are tightly closed, the top surface of the upper and lower sealing cotton is tightly fitted to achieve sealing. The sealing cotton used nowadays has good resilience, however, when it is not used by a user for a long time, the upper and lower covers being tightly locked, resulting in a decrease in the resilience of the sealing cotton, and then a gap will be formed, resulting in an inability to seal. As a result, the machine cannot reach the negative pressure value, and thus cannot vacuum air and seal the packaging bags. Such that the vacuum sealing machine loses the value of use, has a short service life, and causes economic losses to the user.

Embodiment 1
Please refer to FIG. 2, the first sealing strip 11 is connected to the upper cover 10 through the ejection mechanism 30, the first sealing strip 11 is connected with the ejection mechanism 30, and the ejection mechanism 30 ejects the first sealing strip 11 outward to abut against the second sealing strip 21. The ejection mechanism 30 includes a fixing seat 31, and a side of the fixing seat 31 facing away from the first sealing strip 11 is provided with a spring 32, and the spring 32 is in a compressed state. The upper cover 10 is provided with a limit groove for limiting a position of the fixing seat 31, and the fixing seat 31 abuts against a notch of the limit groove and slidable in the limit groove. The fixing seat 31 includes a fixing block 311 and a limit plate 312 extending outward from opposite sides of the fixing block 311. The first sealing strip 11 is fixed on the fixing block 311, and the fixing block 311 is limited at the notch of the limit groove. The limit plate 312 is clamped to an outer edge of the limit groove. The ejection mechanism 30 further includes a fixing plate 33, the fixing plate 33 may be fixed in the upper cover 10, and the spring 32 is arranged between the fixing plate 33 and the fixing seat 31. The fixing plate 33 may be detachably connected to the upper cover 10, one end of the spring 32 is fixedly connected to the fixing plate 33, and the other end is fixedly connected to the fixing seat 31.
In this embodiment, since the spring 32 is provided on the side of the fixing seat 31 facing away from the first sealing strip 11, and the spring 32 is in a compressed state, the first sealing strip 11 will be pushed out by the fixing seat 31 under an elastic force of the spring 32, so that the resilience of the first sealing strip 11 is reduced, and thus the first sealing strip 11 will be pushed out by the fixing seat 31 until it abuts against the second sealing strip 21 seal when the height protruding from the upper cover 10 is reduced. The fixing seat 31 slides in the limit groove, so that an outward movement direction of the first sealing strip 11 is determined, and thus it can abut against the second sealing strip 21 in position. The limit plate 312 limits the distance that the fixing seat 31 moves outwards, so that the fixing seat 31 can push the first sealing strip 11 into contact with the second sealing strip 21 without falling out of the upper cover 10, thereby ensuring an entire structure stability. One end of the spring 32 is fixed to the fixing plate 33 so that the spring 32 can always maintain a compressed state, thereby pushing the fixing seat 31 outward. The spring 32 is fixedly connected to the fixing plate 33 and the fixing seat 31. The fixing plate 33 is detachably installed in the upper cover 10, which not only ensures that the spring 32 will not appear in an action of dislocation, but also enables the entire ejection mechanism 30 to be replaced.

The fixing plate 33 may be detachably connected to the base 20, one end of the spring 32 is fixedly connected to the fixing plate 33, and the other end is fixedly connected to the fixed base 31.
In this embodiment, since the spring 32 is provided on the side of the fixing seat 31 facing away from the second sealing strip 21, and the spring 32 is in a compressed state, then the second sealing strip 21 will be pushed out by the fixing seat 31 under the elastic force of the spring 32, so that the resilience of the second sealing strip 21 is reduced, and thus the second sealing strip 21 will be pushed out by the fixing seat 31 until it abuts against the first sealing strip 11 seal, when the height protruding from the base 20 is reduced. The fixing seat 31 slides in the limit groove, so that the outward movement direction of the second sealing strip 21 is determined, and thus it can abut against the first sealing strip 11 in position. The limit plate 312 limits the distance that the fixing seat 31 moves outward, so that the fixing seat 31 can push the second sealing strip 21 to abut the first sealing strip 11, without coming out of the base 20, ensuring the entire structure stability. One end of the spring 32 is fixed to the fixing plate 33, so that the spring 32 can always maintain a compressed state, thereby pushing the fixing seat 31 outward.
