Description

Technical field:

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

[0002] Vacuum packaging machines are widely used in the field of food packaging. Generally speaking, when using, put food or food materials into a special packaging bag, align the bag opening of the packaging bag with the suction nozzle of the vacuum packaging machine, let the suction nozzle penetrate into the bag opening, and place the bag opening of the packaging bag on the seat of the vacuum packaging machine corresponding to the hot melt unit. At this time, press down the upper cover to close the bag opening, and the negative pressure suction force will extract the air in the packaging bag through the suction nozzle. Then, the packaging bag is heated and sealed by the hot melt unit of the vacuum packaging machine. The air in the packaging bag is extracted and the bag opening is sealed by hot melt to maintain the state that the food or ingredients in the bag are isolated from the air.

[0003] However, the temperature of the hot melt unit will not drop to normal temperature instantly after use and before the next heating. Especially when the user uses it continuously for a long time, the interval between two uses may reach tens of seconds. At this time, the accumulated heat of the hot melt unit will increase accordingly, making it impossible for the temperature of the hot melt unit to drop. As a result, two situations may occur during subsequent use. One is that as soon as the bag mouth of the packaging bag is placed at the corresponding hot melt unit, the bag mouth will be hot-melted due to the temperature not dropping, and it will be sealed before the air is completely extracted, so it is impossible to achieve a vacuum sealing effect; the other is that before the user has placed the packaging bag, part of the area is hot-melted because it contacts the hot melt unit, causing the packaging bag to be hot-melted in the place where it is not desired to be hot-melted.

[0004] The solution in the prior art is to require the user to stop using the vacuum packaging machine after a certain number of uses and continue to use it after the hot melt unit cools down. However, this practice seriously affects the efficiency of use. The user must spend time waiting for the cooling, which damages the user experience. Summary of the invention:

[0005] The technical problem to be solved by the present invention is to provide a vacuum packaging machine which can automatically cool down, so that users can use it for a long time without stopping the machine to wait for cooling down.

[0006] The technical solution of the present invention is to provide a vacuum packaging machine capable of automatically cooling down, comprising:

[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 component 20, and a negative pressure component 30.

[0029] The main body 10 mentioned above includes a base 11 and a handle 12. A hollow box body 111 is disposed on the base 11. The base 11 has a working plane 112. The working plane 112 is located on one side of the hollow box body 111. The working plane 112 is provided with at least one barrier strip 113 disposed along the long side direction. In one embodiment, the number of the barrier strips 113 can be increased according to demand, or the width can be narrowed and cut into multiple strips. A long hole 114 is formed through the working plane 112, and the long hole 114 is between the barrier strip 113 and the box body 111. The handle 12 is pivotally disposed on the base 11 away from the working plane 112. The handle 12 has a pivoting portion 121 and a working surface 122. The handle 12 is pivotally connected to the base 11 by the pivoting portion 121. In one embodiment, the handle 12 is U-shaped and has two ends as the pivoting portions 121, which are 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 arranged along the long side direction, wherein one pressure strip 123 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 long side 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 paved with a heat-resistant layer 23, and 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 connection pipe 33 is connected between the negative pressure source 31 and the suction nozzle 32, and the exhaust connection pipe 34 is connected between the negative pressure source 31 and the outside of the base 11. In one embodiment, the exhaust connection pipe 34 is connected between the negative pressure source 31 and the exhaust hole 115 of the base 11, and part of the suction connection pipe 33 or the exhaust connection 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 connection pipe 33 and the exhaust connection 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 connection pipe 33 is located in the long hole 114 and is close to the fixing plate 21 of the hot melt assembly 20; in another embodiment (as shown Figure 5 As shown in FIG. 1 , 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. Figure 4 or Figure 5 The position where the air intake connecting pipe 33 is set as shown may also be the position where the air exhaust connecting pipe 34 is set.

[0032] When in use, the bag opening of the packaging bag is placed on the working plane 112 of the base 11, and the bag opening is placed flat on the hot melt component 20, and then the handle 12 is pivoted so that the pressure strip 123 on the handle 12 corresponds to the hot melt component 20 and the barrier strip 113, and the bag opening of the packaging bag is pressed flat therein. When the negative pressure source 31 acts to generate suction, the air in the packaging bag passes through the bag opening, the suction nozzle 32, and then through the suction connecting pipe 33 to extract the air in the packaging bag. After the air is extracted, the bag opening is sealed through the hot melt component 20, and the negative pressure source 31 discharges the air through the exhaust connecting pipe 34. When air passes through the air suction connection pipe 33 and exhausts, the air suction connection pipe 33 and / or the exhaust connection pipe 34 are located in the long hole 114 and are close to the hot melt component 20. The flowing air will automatically take away the residual heat of the hot melt component 20, thereby achieving the effect of cooling the hot melt component 20. Therefore, when performing the actions of vacuuming the packaging bag and hot-melt sealing, the negative pressure component 30 also takes away the heat of the hot melt component 20, and 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 waiting time to wait for the hot melt component 20 to cool down, so the user can 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 instead of flowing into the negative pressure source 31 and causing damage.

[0034] The above is only an explanation of the preferred embodiments of the present invention, which should not be construed as a limitation on the claims. Any equivalent process changes made using the present invention specification are included in the patent protection scope of the present invention.
