The present invention relates to a vacuum packaging machine, and more particularly, the vacuum due to the occurrence of a pressure difference in the vacuum chamber and the vacuum wrapping paper according to the vacuum packaging by partially supporting the opening of the vacuum wrapping paper to be vacuum packed in the vacuum chamber The opening of the wrapping paper is prevented from moving arbitrarily, and the sealing position is always made constant and stable as the sealing operation is performed in a state where the opening of the vacuum wrapping paper is partially compressed.

As is well known, a vacuum packaging machine is a device for heat sealing a package in a vacuum package in a vacuum state. The vacuum packaging machine can be largely classified into a chamber type and a nozzle type according to the vacuum packaging method. Briefly describing the packaging machine of the above classification, first, the chamber type is to force the suction of the air in the chamber by using a vacuum pump to make the inside of the vacuum wrapping paper in a vacuum state, and then heat-sealing the opening, and the nozzle type is the air suction The nozzle is vacuumed inside the vacuum package in a state where the nozzle is inserted into the opening of the package of the vacuum package, and after the vacuum is completed, the suction nozzle is retracted from the vacuum package and heat sealing is performed.

However, in the case of conventionally known vacuum packaging machines, the package 6 is placed on the backing plate 5 in the vacuum chamber 4 formed between the main body 2 and the lid 3 of the vacuum packaging machine 1 as illustrated in FIG. 1. In the case where the vacuum wrapping paper 7 is placed and the vacuum packaging is to be carried out, both openings 7a and 7b of the vacuum wrapping paper 7 placed inside the vacuum chamber 4 are supported by the pedestal 8. And the vacuum chamber when the air is inhaled through the air inlet 11 connected to the vacuum pump 10 because the vacuum operation is performed in a state in which the sealing bar 9 is pressed in a state having a minute clearance of air communication. (4) The inside of the vacuum wrapper 7 and the air pressure difference occurs due to the air intake. That is, when the air is inhaled, the opening portion 7a of the vacuum wrapping paper 7 is opened in a relation that the whole is pressed by a constant pressing force by the pedestal 8 and the sealing bar 9 so that arbitrary movement is suppressed during the vacuum packaging operation. Since air is sucked out through a very fine gap between 7a, it is naturally different from the air suction discharge rate inside the vacuum chamber 4.

Therefore, a pressure difference occurs due to an air suction speed difference between the vacuum chamber 4 and the vacuum package 7 in which the package 6 is placed, and due to the occurrence of the pressure difference, the vacuum package 7 The opening 7a is arbitrarily pulled or irregularly moved from one or part of the pedestal 8 and the sealing bar 9 due to the forced swelling as the air suction speed of the vacuum chamber 4 becomes significantly faster. The problem arises. In particular, this phenomenon occurs in the case of packaging a lot of greasy meat oil is bound to the outside of the opening 7a in the packaging process, which occurs more severe because it easily slips even in a small external force.

Therefore, according to the conventional vacuum packaging machine (1), due to the air pressure difference between the vacuum chamber (4) and the vacuum wrapping paper 7 in accordance with the air intake, the opening portion (7a) of the vacuum wrapping paper (7) to move arbitrarily or partially Therefore, the sealing position is not fixed as shown in (a) of FIG. 2 because one point of the opening portion 7a is mechanically sealed by the sealing bar 9 in a state that the operator does not know at all, or (b) and Likewise, only a part of the sealing work was performed, and the vacuum packing work was often made badly. And, such a bad packing cause is inevitably endured in the inconvenience and inconvenience of repackaging. In particular, such a packaging failure problem greatly reduces the reliability of the vacuum packaging machine, and becomes a factor that prevents the rapid and accurate vacuum packaging operation.

The present invention is invented in order to prevent the packaging failure problem occurring in the conventional vacuum packaging machine as described above, the object of the present invention is that one side of the opening portion of the vacuum packaging paper is stably supported and only partially squeezed by the non-compression Due to the wider opening width, the suction operation of air is made smoothly and smoothly during the vacuum operation, so that there is no difference in pressure with the vacuum chamber, and due to the difference in pressure, the vacuum wrapping paper is swollen or the opening is arbitrarily opened. The present invention provides a vacuum packaging machine that enables a stable and fast packaging operation without a defect because the sealing is made secondary since the sealing is prevented from being pulled out or moved.

The opening part supporting member 130 provided in the vacuum chamber 114 may be appropriately disposed at both sides of the vacuum chamber 114, for example, a location where packaging work is possible, as illustrated in FIG. 3. In addition, the opening part support member 130 may be installed in several pieces as necessary.

The opening part supporting member 130 is provided between the edge inner wall of the main body 112 and the support 118 as shown in FIGS. 3 and 4. Therefore, the opening part 117a of the vacuum wrapping paper 117 mounted on the pedestal 115 at the time of packaging the vacuum wrapping paper 117 may be fitted in a state in which it is stably supported via the pedestal 118.

According to the present invention, the opening part supporting member 130 is formed to be bent to be divided into one side of the support piece (130a) and the support piece (130a), which is fitted to the support holder 131, and the vacuum wrapping paper It is preferable to include a plurality of support wings (130b) to enter the opening portion 117a of the 117 to partially support it.

Subsequently, referring to FIG. 4, the opening part support member 130 is preferably configured to be detachable from the support holder 131 provided in the main body 112, and is detachable from the support holder 131. It is preferable that the opening part supporting member 130 is configured such that the support piece 130a is tightened or released by the operation handle 132 screwed to the screw hole 131a of the support holder 131.

The pressing member 140 is provided at the chamber cover 113 to correspond to the opening part supporting member 130. A guide shaft for compressing an upper portion of one side of the opening part 117a of the vacuum wrapping paper 117 fitted to the opening support member 130, and having one side penetrated through the support part 113a of the chamber cover 113. 141 and an upper portion of one side of the opening part 117a of the vacuum wrapping paper 117 which is provided at the other side of the guide shaft 141 and partially supported by each support wing 130b of the opening part support member 130. It is configured to include a spring-like elastic body 143 interposed between the pressing portion 142 and the support portion 113a and the pressing portion 142 for crimping.

According to the above configuration, the pressing portion 142, the pressing surface 142a made of foam rubber or foamed silicone material in order to maintain a stable pressurized state without slipping against the opening portion 117a of the vacuum wrapping paper 117 to be pressed. This is further provided.

The working state according to the present invention configured as described above will be described.

First, referring to FIG. 4, the opening part supporting member 130 installed with respect to the support holder 131 provided as the main body 112 of the vacuum chamber 114 has a supporting blade 130b in the direction of the pedestal 118. It is also provided so that the height of the support wing 130b is also close to the pedestal 118 so that the opening portion 117a of the vacuum wrapping paper 117 can be stably supported.

In this state, the vacuum package 117 into which the package 116 is placed is placed on the pedestal 118 in the vacuum chamber 114, and then the opening part 117a is pulled to the position of the opening part supporting member 130, and the inside thereof is pulled out. And each support blade 130b is to be fitted. Then, at this time, each of the supporting blades 130b of the opening portion receiving member 130 is put into a predetermined depth into the opening portion 117a. Accordingly, in the vacuum wrapping paper 117, the rear portion in which the package 116 is accommodated and the opening portion 117 in front thereof are aligned with the supporting plate 115 and the pedestal 118 and the opening portion receiving member 130. .

In such a state, when the chamber lid 113 is closed with respect to the main body 112 as shown in FIG. 5, the vacuum chamber 114 is sealed and at the same time, the vacuum in which the support wings 130b of the opening part support member 130 are fitted. The opening part 117a of the wrapping paper 117 is primarily pressed by the lower side of the pressing member 140 provided on the chamber cover 113.

More specifically, as shown in FIG. 6, by the lowering of the pressing member 140, the opening part 117a of the vacuum wrapping paper 117 is formed by each support wing 130b of the opening part receiving member 130. Its upper surface is partially squeezed. At this time, the other side of the opening part 117a that is pressed onto the pressing member 140, for example, the other side which is not pressed by the pressing member 140, is extended in a free state. Therefore, the opening part 117a is partially pressed by the opening part receiving member 130 even though one side is forcibly pressed by the pressing member 140, and the other side that is not pressed is opened in a free state. Because it loses form, it is spread to secure a lot of air suction space during vacuum.

On the other hand, the pressing member 140 for partially compressing the opening portion 117a supported by the opening portion receiving member 130 has a guide shaft 141 between the support portion 113a and the pressing portion 142 to the elastic body 143. Before the chamber cover 113 is covered because it is elastically installed (see FIG. 4), the chamber body 113 extends further below the sealing bar 119 by the tension force of the elastic body 143, but when the chamber cover 113 is pressed and closed, The guide shaft 141 moves upward with respect to the support portion 113a by the pressing portion 142 at the lower end of the lower portion of the support portion 113a. As a result, the elastic body 143 is compressed between the support part 113a and the pressing part 142.

Therefore, the pressing portion 142 exerts a strong compressive force with respect to the opening portion 117a interposed between the opening portion receiving member 130 by the elastic force of the elastic body 143, provided as a lower end of the pressing portion 142. The compressed surface 142a can be stably compressed without slipping when pressed.

As described above, even when the pressing member 140 compresses the opening part 117a of the vacuum wrapping paper 117, the sealing bar 119 is maintained in a constant distance without being in contact with the lower pedestal 118.

When the primary crimping and fixing of the vacuum wrapping paper 117 is performed as described above, the air inside the vacuum wrapping paper 117 and the vacuum chamber 114 are forcibly sucked through the air inlet 121 by the operation of the vacuum pump 120. Vacuum is achieved. At this time, since the air existing in the vacuum wrapping paper 117 is partially compressed by the pressing member 140, a rapid vacuum suction operation is performed through the non-compression space portion, and by such a rapid vacuum suction operation The pressure difference is not generated between the vacuum wrapping paper 117 and the vacuum chamber 114. Therefore, during the vacuum operation by the vacuum pump 120, the vacuum wrapping paper 117 is prevented from swelling due to the pressure difference generated during the vacuum operation process, the opening portion 117a is the opening portion supporting member 130 and the pressing member 140. Artificial movement or falling out of the

When the vacuum operation is completed in the state in which the opening part 117a is stably compressed by the pressing member 140, the sealing bar 119 provided in the chamber cover 113 as shown in FIG. By lowering the pedestal 118 by the action of 119a, a portion interposed between the pedestal 118, for example, a sealing position, is heated and sealed. Heat sealing by the sealing bar 119 is typically provided with a heating wire for sealing in the sealing bar 119, and also a valve for supplying and blocking air to the air bag 119a (not shown). Of course, such a configuration is known in the vacuum packaging machine.

Therefore, in the present invention, the sealing bar 119 as the opening part 117a of the vacuum wrapping paper 117 is partially compressed by the opening part supporting member 130 and the pressing member 140 is made in the vacuum operation and the sealing operation. The sealing position of the opening part 117a heat-sealed by) can always be made stable and reliably.

On the other hand, when the sealing operation is completed, when the chamber cover 113 is opened from the main body 112, the pressing member 140 is raised along the chamber cover 113. Then, the pressing portion 142 is released from the pressing force 117a, the pressing force is released, it is returned to the state of Figure 4 by the tensile force of the elastic body 143.

When the pressing force by the pressing member 140 is released in this way, the vacuum packaging operation is completed through the process of drawing the vacuum packaging paper 117 from the vacuum chamber 114.

According to the present invention as described above, since the opening part of the vacuum wrapping paper vacuum wrapping paper of the package is forcibly crimped by the opening portion supporting member and the pressurizing portion, and the air suction operation inside the vacuum wrapping paper is smoothly made through the non-pressing portion. Since the pressure difference with the inside of the vacuum chamber does not occur and the occurrence of the pressure difference is prevented, the vacuum wrapping paper is not swollen during the vacuum operation, or the opening part is not separated or moved between the pressing member. The sealing position is to provide a remarkable effect that can always be made constant and secure.

In addition, there is an advantage that the maintenance and disassembly and assembly is easy by providing the opening portion receiving member detachably attached to the support holder.

Although the present invention has been described with reference to the accompanying drawings, the present invention is not limited thereto, and many modifications and changes can be made without departing from the scope of the claims, and such changes can be implemented by those skilled in the art. I will be inside.
