Description

Technical field:

[0001] The utility model belongs to the technical field of vacuum packaging machines, in particular to a vacuum packaging machine capable of automatically cooling. Background technology:

[0002] Vacuum packaging machines are widely used in the field of food packaging. Generally speaking, when using it, food or food materials are placed in a special packaging bag, the bag opening of the packaging bag is aligned with the suction nozzle of the vacuum packaging machine, the suction nozzle is inserted into the bag opening, and the bag opening of the packaging bag is placed on the base of the vacuum packaging machine corresponding to the hot melt unit. At this time, the upper cover is pressed down to close the bag opening. After the negative pressure suction force draws out the air in the packaging bag through the suction nozzle, the packaging bag is then heated and sealed by the hot melt unit of the vacuum packaging machine. The air in the packaging bag is drawn out and the bag opening is hot-melt-sealed to keep the food or ingredients in the bag isolated from the air.

[0003] However, the temperature of the hot melt unit does not instantly drop to room temperature between use and the next heating. This is especially true for long-term, continuous use, where the interval between uses can be tens of seconds. During this time, the accumulated heat in the hot melt unit increases, preventing the unit's temperature from dropping. This can lead to two potential issues during subsequent use. First, the bag opening can melt as soon as it is placed against the hot melt unit, causing the bag to be sealed before all air is completely extracted, thus failing to achieve a true vacuum seal. Second, the bag can melt due to contact with the hot melt unit before the user has placed the bag properly, resulting in areas of the bag being melted where they were not intended.

[0004] The solution in the existing technology is to require the user to stop using the vacuum packaging machine after a certain number of uses and wait for the hot melt unit to cool down before continuing to use it. However, this practice seriously affects the efficiency of use. The user must spend time waiting for cooling, which damages the user experience. Utility model content:

[0005] The technical problem to be solved by the utility model is to provide a vacuum packaging machine which can automatically cool down, so that users can use the machine for a long time without having to stop the machine and wait for cooling down.

[0006] The technical solution of the utility model is to provide a vacuum packaging machine capable of automatically cooling, which comprises:

Specific implementation method:

[0027] The present invention will be further described below with reference to the accompanying drawings:

[0028] See also Figure 1 and Figure 2 As shown, the present invention includes a main body 10 , a hot melt assembly 20 , and a negative pressure assembly 30 .

[0029] The main body 10 includes a base 11 and a handle 12. A hollow housing 111 is mounted on the base 11. The base 11 has a work surface 112 located on one side of the hollow housing 111. This work surface 112 is provided with at least one barrier strip 113 disposed along its longitudinal direction. In one embodiment, the number of barrier strips 113 can be increased as needed, or the width can be reduced by cutting into multiple strips. A slot 114 is formed through the work surface 112, located between the barrier strip 113 and the housing 111. The handle 12 is pivotally mounted on the base 11 away from the working plane 112. The handle 12 has a pivotal portion 121 and a working surface 122. The handle 12 is pivotally connected to the base 11 via the pivotal portion 121. In one embodiment, the handle 12 is U-shaped, with two ends serving as the pivotal portions 121, respectively pivotally connected to two sides of the box body 111. The working surface 122 corresponds to the working plane 112 of the base 11 and is provided with two pressure strips 123 disposed along the longitudinal direction, one of which corresponds to the barrier strip 113 of the base 11. A vent 115 may be provided on the side of the base 11.

[0030] The aforementioned hot melt assembly 20 is disposed on the working plane 112 of the base 11 along the longitudinal direction, and the hot melt assembly 20 is located between the barrier strip 113 and the box body 111 and is relatively located above the long hole 114. In one embodiment, please refer to Figure 4 As shown, the hot melt assembly 20 includes a fixing plate 21 and a heating strip 22. The heating strip 22 is arranged on the fixing plate 21. The fixing plate 21 is used to fix the heating strip 22 on the base 11. The heating strip 22 is used to connect to a power source (generally a power source) to increase the temperature and generate heat when the power source is started. In one embodiment, the top and bottom surfaces of the heating strip 22 can be covered with a heat-resistant layer 23. The heat-resistant layer 23 is used to protect the heating strip 22 and transfer temperature. In another embodiment, please refer to Figure 5 As shown, the bottom surface of the fixing plate 21 may be provided with a rubber layer 24 .

[0031] See also Figures 1 to 4As shown, the aforementioned negative pressure component 30 is disposed in the main body 10, and the negative pressure component 30 includes a negative pressure source 31, a suction nozzle 32, an air suction connection pipe 33 and an air exhaust connection pipe 34. The negative pressure source 31 is disposed in the box body 111 and provides negative pressure suction. In one embodiment, the negative pressure source 31 is a pump. The suction nozzle 32 passes through the box body 111 and can be selectively extended on the working plane 112 of the base 11. The suction connecting pipe 33 is connected between the negative pressure source 31 and the suction nozzle 32, and the exhaust connecting pipe 34 is connected between the negative pressure source 31 and the outside of the base 11. In one embodiment, the exhaust connecting pipe 34 is connected between the negative pressure source 31 and the exhaust hole 115 of the base 11, and part of the suction connecting pipe 33 or the exhaust connecting pipe 34 is located in the long hole 114 of the base 11 and abuts against the hot melt component 20; in another embodiment, both the suction connecting pipe 33 and the exhaust connecting pipe 34 may be partially located in the long hole 114 of the base 11 and abut against the hot melt component 20 (not shown in the figure). In one embodiment (such as Figure 4 As shown), the suction connecting pipe 33 is located in the long hole 114 and is abutted against the fixing plate 21 of the hot melt assembly 20; in another embodiment (as shown Figure 5 As shown), the suction connection pipe 33 is located in the slot 114 and is in contact with the rubber layer 24 of the hot melt assembly 20. In one embodiment, the aforementioned Figure 4 or Figure 5 The position where the air intake connecting pipe 33 is provided may also be the position where the air exhaust connecting pipe 34 is provided.

[0032] During use, the bag opening is placed on the working surface 112 of the base 11 and laid flat on the hot melt assembly 20. The handle 12 is then pivoted so that the pressure strip 123 on the handle 12 corresponds to the hot melt assembly 20 and the barrier strip 113, and the bag opening of the bag is pressed flatly therein. When the negative pressure source 31 acts to generate suction, the air in the bag passes through the bag opening, through the suction nozzle 32, and then through the suction connection tube 33 to be extracted from the bag. After the air is extracted, the bag opening is sealed through the hot melt assembly 20. In addition, the negative pressure source 31 discharges the air through the exhaust connection tube 34. When air passes through the suction connection pipe 33 and exhausts, the suction connection pipe 33 and / or the exhaust connection pipe 34 are located in the long hole 114 and abut against the hot melt component 20. The flowing air will automatically remove the residual heat of the hot melt component 20, thereby achieving the effect of cooling the hot melt component 20. Therefore, during the vacuuming and hot-melt sealing operations of the packaging bag, the negative pressure component 30 also removes the heat of the hot melt component 20. The temperature of the hot melt component 20 can be reduced during the operation of the negative pressure component 30. The user does not need to spend extra time waiting for the hot melt component 20 to cool down, so the user can continue to use the vacuum packaging machine of the present invention for a long time.

[0033] Furthermore, if Figure 2 As shown, the suction connecting pipe 33 of the negative pressure component 30 is between the negative pressure source 31 and the suction nozzle 33, and can first pass through a dirt collecting box 40, that is, the suction connecting pipe 33 is divided into a front suction connecting pipe and a rear suction connecting pipe. The front suction connecting pipe connects the suction nozzle 32 and the dirt collecting box 40, and the rear suction connecting pipe connects the dirt collecting box 40 and the negative pressure source 31. When the negative pressure source 31 starts to provide negative pressure suction, the fluid drawn by the suction nozzle 32 will first enter the dirt collecting box 40 through the front suction connecting pipe, and then reach the negative pressure source 31 through the rear suction connecting pipe. The rear suction connecting pipe can be provided with a baffle at the inlet that only allows gas to pass through. If the fluid entering the suction connecting pipe 33 from the suction nozzle 32 accidentally inhales liquid or solid in the packaging bag, it can be blocked in the dirt collecting box 40 and will not flow into the negative pressure source 31 and cause damage.
