The invention relates to the technical field of packaging equipment and kitchen equipment (low-temperature and vacuum cooking), and in particular to a novel vacuum packaging machine.
As shown in
For such (chamber) vacuum packaging machines, in order to ensure that the packaging bag achieves a good heat-sealing effect, the bag mouth of the packaging bag must be kept flat. However, when the packaging bag contains irregularly shaped food (objects) and the food (objects) are placed horizontally or at an inclined angle, it is difficult to effectively ensure the flatness of the bag mouth. Especially when the packaging bag contains too many objects, these objects will cause the bag mouth to be irregular or wrinkle seriously, which will affect the heat-sealing effect and cause air leakage. When the packaging bag contains liquid, dust, or granular objects, the bag mouth of the packaging bag is difficult to be stabilized on a heater flatly due to fluidity of these objects, and it is more difficult to ensure a good heat-sealing effect at this time. In addition, these objects have fluidity which is limited by placement status, i.e., placed horizontally or at a certain inclined angle, in order to prevent contents from leaking out from the bag mouth of the packaging bag, the amount of liquid, dust or granular objects in the packaging bag is greatly limited. That is, since the vacuum chamber 10 of the existing (chamber) vacuum machine is designed to be horizontal or at a certain inclined angle, there will be two problems: one is that it is difficult to keep the bag mouth of the packaging bag flat, and the vacuum packaging machine does not achieve an ideal heat-sealing effect of the packaging bag; and the other is that the vacuum packaging machine cannot seal a packaging bag containing a large amount of fluid objects such as liquid, dust or granular objects.
In order to overcome the technical problem that the existing vacuum packaging machine cannot seal a packaging bag containing a large number of fluid objects, the invention provides a novel vacuum packaging machine capable of sealing a packaging bag containing a large number of fluid objects.
In order to achieve the aforementioned objective, the invention provides a novel vacuum packaging machine suitable for sealing a packaging bag, wherein the novel vacuum packaging machine comprises a machine body, a vacuum cover and a bag hanging assembly. A vacuum chamber enabling a packaging bag (4) to be vertically placed is provided in the machine body. The vacuum cover is provided on the machine body and corresponds to the vacuum chamber. The bag hanging assembly is provided at the upper part of the vacuum chamber.
In the aforementioned novel vacuum packaging machine, the bag hanging assembly comprises a hanging part and a bag hanging part;
the hanging part is provided at the upper part of the vacuum chamber, and the bag hanging part is installed on the hanging part; and
the bag hanging part comprises at least two bag hanging units, and one or more of the at least two bag-hanging units are slidable relative to the hanging part.
In the aforementioned novel vacuum packaging machine, the hanging part comprises a guide rail which is fixed at the upper part of the vacuum chamber; the bag hanging part comprises two bag hanging units denoted as a first bag hanging unit and a second bag hanging unit respectively; the first bag hanging unit is fixedly installed on the guide rail; and the second bag hanging unit is installed on the guide rail and can reciprocate away from and close to the first bag hanging unit relative to the guide rail.
In the aforementioned novel vacuum packaging machine, the first bag hanging unit comprises a first hook fixedly installed on the guide rail; the second bag hanging unit comprises a sliding member and a second hook provided on the sliding member for vertically hanging a packaging bag; and the sliding member is installed on the guide rail and can drive the second hook to reciprocate away from and close to the first hook on the guide rail.
In the aforementioned novel vacuum packaging machine, the sliding member is a sliding block, an upper surface of the guide rail is provided with sawteeth, and a side of the sliding block opposite to the sawteeth on the guide rail is provided with an elastic piece; and the elastic piece is meshed with the sawteeth on the guide rail so that the sliding block moves in a straight reciprocating motion.
In the aforementioned novel vacuum packaging machine, the novel vacuum packaging machine further comprises a heat-sealing assembly, the heat-sealing assembly comprises a heating part and a heat-sealing strip; the heating part is provided in the vacuum chamber, and the heat-sealing strip is provided on an inner side wall of the vacuum cover and corresponds to the heating part.
In the aforementioned novel vacuum packaging machine, the novel vacuum packaging machine further comprises a horizontal telescoping part installed on the machine body; a telescoping end of the horizontal telescoping part is provided with the heating part and can drive the heating part to reciprocate away from and close to the heat-sealing strip.
In the aforementioned novel vacuum packaging machine, the heating part comprises a heater and a position-limiting member; the telescoping end of the telescoping part is provided with a fixing block for installing the heater;
the position-limiting member is installed between the heater and the fixing block, so that the heater and the position-limiting member are stationary relative to each other during a heat-sealing process.
In the aforementioned novel vacuum packaging machine, the novel vacuum packaging machine further comprises a vacuumizing assembly comprising a vacuum pump and an exhaust port provided on the machine body; the exhaust port communicates with the vacuum chamber, and the suction port of the vacuum pump communicates with the exhaust port.
In the aforementioned novel vacuum packaging machine, the novel vacuum packaging machine further comprises a control unit provided on the machine body.
The invention has the following beneficial effects in comparison with the prior art:
Since the vacuum chamber enabling the packaging bag to be placed vertically is provided in the machine body along the height direction of the machine body, and the bag hanging assembly is provided at the upper part of the vacuum chamber, when the packaging bag is sealed by the vacuum packaging machine of the invention, the packaging bag is placed vertically, and the bag mouth of the packaging bag is located at the upper part of the vacuum chamber through the bag hanging assembly, so that when the product contained in the packaging bag is a fluid object, there is no need to worry about the fluid object leaking out from the bag mouth. Therefore, the vacuum packaging machine of the invention can seal a packaging bag containing a larger amount of fluid objects than vacuum packaging machines in the prior art;
In addition, the novel vacuum packaging machine of the invention can make it easier for the packaging bag to keep the bag mouth flat when the packaging bag contains irregular or large-sized objects, and thus it is easier to obtain a good heat-sealing effect.

The bag hanging part 32 comprises at least two bag hanging units, and one or more of the at least two bag-hanging units are slidable relative to the hanging part 31. In this way, on the one hand, the vacuum packaging machine according to the embodiment of the invention can adapt to packaging bags 4 with different widths. On the other hand, the packaging bag 4 (and its contents) will extend vertically under the action of its own gravity. Moreover, since one or more of the at least two bag hanging units are slidable relative to the hanging part 31, the bag mouth of the packaging bag 4 can be kept flat horizontally by adjusting the slidable bag hanging units, thereby improving the heat-sealing effect.
Obviously, if the packaging bag 4 to be sealed by the novel vacuum packaging machine 100 according to the embodiment of the invention has a constant width, the bag hanging units included in the bag hanging part 32 may also be stationary relative to the hanging part 31.
