Description

Technical Field

[0001] The utility model relates to the technical field of vacuum sealers, in particular to a vacuum sealer with a short-range sealing function. Background Art

[0002] A vacuum sealer is a device used to seal food, medicine, and other items. It works by extracting air from the packaging, thereby creating a low-oxygen environment, which helps extend the shelf life of the items and prevents oxidation and bacterial growth. Vacuum sealers are often used in homes, restaurants, and the food processing industry to preserve the freshness of food and extend its shelf life.

[0003] The vacuum chamber and the heat sealing strip of the existing vacuum sealer are arranged at a certain distance. When the sealed bag is used, a large blank space is left between the heat sealing area and the bag opening of the sealed bag, and the blank space is useless. In addition, when cutting the sealed bag before use, a long space needs to be reserved for heat sealing, which increases the consumption rate of the sealed bag and causes waste of the sealed roll bag. Therefore, a vacuum sealer with a short-range sealing function is needed. Utility Model Content

[0026] In the description of the present invention, the terms "first" and "second" are used for descriptive purposes only and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present invention, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0027] Reference Figure 1-8 As shown, a vacuum sealing machine with a short-range sealing function comprises:

[0028] A main body 1 and a cover 2 rotatably arranged above the main body 1; the main body 1 is provided with a first vacuum chamber 12, the first vacuum chamber 12 is configured to provide vacuum extraction for the sealing bag, and a heat sealing component 3 is arranged in the first vacuum chamber 12, the heat sealing component 3 is configured to provide heat sealing for the sealing bag.

[0029] By arranging the heat sealing component 3 in the first vacuum chamber 12, the distance between the heat sealing area on the sealing bag and the bag opening of the sealing bag is shortened, and the blank space on the sealing bag is reduced, so that when cutting the sealing bag, there is no need to reserve too much heat sealing space, which reduces the consumption rate of the sealing bag and saves the use of the sealing roll bag; by arranging the baffle 13 in the first vacuum chamber 12, it is prevented that the sealing bag is excessively extended into the machine body, resulting in the sealing bag being unable to perform vacuum heat sealing treatment normally; by arranging the adhesive tape 34 on the heat sealing component 3, it is helpful to isolate part of the heat released by the heat sealing strip 32, while ensuring the normal sealing of the sealing bag, avoiding the sealing bag being melted through by the heat sealing strip 32 due to excessive temperature.

[0030] Furthermore, the main body 1 is provided with a circle of first sealing ring 11 along the edge of the first vacuum chamber 12, the machine cover 2 is provided with a second vacuum chamber 23 corresponding to the first vacuum chamber 12, and the machine cover 2 is provided with a circle of second sealing ring 21 along the edge of the second vacuum chamber 23. When the machine cover 2 and the main body 1 are closed, the first vacuum chamber 12 and the second vacuum chamber 23 constitute a vacuum chamber for providing air extraction for the sealing bag. The first sealing ring 11 and the second sealing ring 21 are combined to form a closed space, which effectively prevents outside air from entering the vacuum chamber, and through a plurality of exhaust holes arranged in the vacuum chamber, the vacuum chamber can reach a vacuum state, and then the air in the sealing bag can be extracted to make the sealing bag reach a vacuum state.

[0031] Furthermore, a heat sealing component 3 is provided in the first vacuum chamber 12 of the main body 1, and a plurality of baffles 13 are provided in the first vacuum chamber 12 on a side away from the heat sealing component 3. The baffle 13 is used to prevent the sealing bag from transitioning into the main body 1, and an inclined plate is formed on the side of the baffle 13 close to the second vacuum chamber 23, and the angle between the inclined plate and the vertical direction is controlled to be 110° to 135°. The inclined plate has the effect of guiding the sealing bag opening to enter the first vacuum chamber 12, and can prompt the operator that the sealing bag has been placed in place, thereby shortening the distance between the heat sealing area on the sealing bag and the bag opening of the sealing bag. In order to facilitate the operation of the heat sealing bag and make the structure more reasonable, in this embodiment, the heat sealing component 3 is preferably arranged on a side of the first vacuum chamber 12 close to the opening of the main body 1. If the heat sealing component 3 is arranged in the middle position of the first vacuum chamber 12 or on a side away from the opening of the main body 1, it is not conducive to the placement of the baffle 13, and the sealing bag is easily transitioned into the main body 1 during use, resulting in a waste of sealing bag space and an increase in the consumption rate of the sealing bag.

[0032] Furthermore, a pressure strip 22 is provided on one side of the second vacuum chamber 23 of the machine cover 2 corresponding to the heat sealing component 3. The pressure strip 22 is used to squeeze the two side surfaces of the sealing bag and cooperate with the heat sealing component 3 to make them melt and adhere to achieve the sealing effect. An air hole 24 is provided in the second vacuum chamber 23. The air hole 24 is used to control the opening of the air hole 24 through the battery valve to allow the outside air to enter the vacuum chamber after the vacuum sealer completes the evacuation and sealing operations on the sealing bag, so that the internal pressure of the vacuum chamber is restored to a normal value, which is convenient for opening the machine cover 2.

[0033] Furthermore, the heat sealing assembly 3 includes: a bracket 31, a heat sealing strip 32, an insulating plug 33 and an adhesive tape 34; the bracket 31 is provided with a through groove near the second vacuum chamber 23, and the through groove can dissipate heat for the heat sealing strip 32; the insulating plug 33 is clamped at both ends of the bracket 31 through the through groove, and the bracket 31 is provided with a heat sealing strip 32 on the side away from the through groove. The heat sealing strip 32 melts the sealing bag by electric heating, and cooperates with the pressure strip 22 to achieve the sealing effect. The heat sealing strip 32 is covered with a layer of adhesive tape 34, which is helpful to isolate part of the heat released by the heat sealing strip 32, while ensuring the normal heat sealing of the sealing bag, to prevent the sealing bag from being melted through by the heat sealing strip 32 due to excessive temperature, resulting in the sealing failure gas flowing into the sealing bag.

[0034] Furthermore, the specific implementation of the utility model is as follows:

[0035] According to the size of the food or article to be sealed, a suitable length is drawn out from the sealing roll bag provided in the main body 1, and is cut using the cutting assembly provided on the main body 1. One end of the sealing bag is first heat-sealed, and the food or article is put into the bag, and the unsealed end of the other end is inserted into the main body 1. When the bag opening of the sealing bag touches the baffle 13, the cover 2 is closed to perform the vacuuming and heat-sealing operation, thereby completing the vacuuming and heat-sealing of the sealing bag.

[0036] The above description is only the preferred implementation of the utility model, and is not intended to limit the utility model. For those skilled in the art, the utility model can have various modifications and changes. 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.
