The present invention relates to a vacuum packaging machine, and in particular, it can implement a vacuum packaging machine that is easily switched automatically and manually according to the user's convenience by a double-pressing structure, and vacuum various types of vacuum packaging paper regardless of whether or not embossing The present invention relates to a vacuum packaging machine having a double pressing device, which can be packaged as well as suitable for controlling the strength of the vacuum pressure appropriately for the contents regardless of the automatic mode or the manual mode.

In general, the vacuum wrapping paper is a container useful for preventing the oxidation of food and for long-term storage by putting food in the vacuum wrapping paper and then extracting air to seal the food.

Therefore, recently, an automatic vacuum packaging machine that can easily package food and other contents using a vacuum packaging paper has been widely used.

1 is a perspective view for explaining a conventional automatic vacuum packaging machine.

As shown, the conventional automatic vacuum packaging machine is composed of a lower case 10, the upper case 20 which is hinged to the lower case 10 to open and close the upper surface of the lower case 10, the The lower case 10 is connected to the lower packing 30, the air inlet 50 formed in the lower chamber 35, and the air inlet 50 to form a lower chamber 35 in a left and right direction therein. It is provided with a vacuum pump (not shown) that sucks air and a heating bar 60 that is installed in the left and right directions in front of the lower packing 30 and generates heat. In addition, in the upper case 20, the compression packing 70 is installed at a position corresponding to the heating bar 60, and the upper packing 40 is formed to form the upper chamber 45.

Looking at the operation of the conventional automatic vacuum packaging machine as follows.

First, the user puts the contents 80 such as foods to be stored in the vacuum wrapping paper 90 and places the inlet portion of the vacuum wrapping paper 90 in the lower chamber 35 of the lower case 10 and the upper case ( 10) is rotated to bring the lower packing 30 and the upper packing 40 into close contact, thereby making the chambers 35 and 45 closed.

In such a state, when a vacuum pump (not shown) is operated by pressing a predetermined on / off switch, the air suction port 50 connected to the vacuum pump sucks air in the sealed space. As a result, the enclosed space is in a vacuum state and sucks the air therein through the inlet of the vacuum packing paper 90 held by the lower packing 30 and the upper packing 40. At this time, as the vacuum pressure of the sealed space consisting of the chambers 35 and 45 increases, the lower packing 30 and the upper packing 40 are gradually compressed, so that the upper case 20 is further attached to the lower case 10. In close contact with the pressing packing 70, the pressing bar 60 is further pressed to a level capable of sealing the vacuum wrapping paper.

Thereafter, when the pressure inside the vacuum wrapping paper reaches a preset value, the heating bar 60 operates to generate heat. Then, the vacuum packing paper is sealed while the lower vinyl and the upper vinyl of the vacuum packing paper 90 that are compressed and bitten between the pressing packing 70 and the heating bar 60 are heat-sealed.

However, the conventional automatic vacuum packaging machine was able to seal the vacuum wrapping paper 90 by operating the heating bar 60 only when the vacuum pressure in the vacuum wrapping paper 90 reaches the set value. Accordingly, the vacuum wrapping paper 90 could not be sealed while the vacuum pressure did not reach the set value. For this reason, foods or contents that are easily broken or damaged under high vacuum pressure may be difficult to store using vacuum packaging.

In addition, the conventional automatic vacuum packaging machine could not be vacuum packed at high vacuum pressure using the output of the vacuum pump to the maximum. This is because turbid noise or vibration often occurs when the output of the vacuum pump is maximized as much as possible. When the vacuum pressure setting is adjusted to the maximum output value of the vacuum pump in the automatic vacuum packaging machine, there is a high possibility of noise and vibration occurring during vacuum packaging. Therefore, in order to prevent this problem in advance, it is inevitable to set a low level of vacuum pressure as the set point compared to the optimum output value of the vacuum pump.

In addition, there is a problem that can not be used for general vacuum wrapping paper that does not artificially form an air flow path, such as embossing. That is, in the state in which the lower packing 30 and the upper packing 40 are engaged, the air is sucked in through the inlet of the vacuum packing paper, so if the vacuum packing paper that is not formed with embossing or its equivalent is used. The upper and lower plastics of the vacuum packing paper held by the lower packing 30 and the upper packing 40 stick to each other, and thus the air inside the vacuum packing paper cannot be discharged. For reference, special vacuum packaging paper with embossing is difficult to manufacture and expensive. Therefore, in some cases, it may be difficult for the vacuum packaging paper to be more expensive than the contents requiring the vacuum packaging.

Accordingly, the present invention has been proposed to solve the conventional problems as described above, and an object of the present invention is to provide a vacuum packaging machine having a double pressing device having a double-pressing structure to enable a variety of applications.

Hereinafter, the structure of the vacuum packing machine provided with the double pressing device by this invention is demonstrated centering on the vacuum packing machine provided with the double pressing device.

Figure 2 is a perspective view of the present invention, Figure 3 is a partially exploded perspective view for explaining the configuration of the present invention, Figure 4 is a partially exploded perspective view showing a state that the body cover is covered.

As shown in the drawing, the present invention includes a main body base 100, a main body cover 200, a suction means 300, a sealing means 400, and a sealing means operating means 500 having a double pressing device. It is configured to include, and provide a structure of the automatic and manual combined type, and even when operating in the automatic mode, it is possible to seal the vacuum wrapping paper 90 at any time regardless of the vacuum pressure applied to the inside of the vacuum wrapping paper 90. Hereinafter, each of the above components will be described in detail.

First, the main body base 100 and the main body cover 200 are hinged to be rotatable with each other so that the main body cover 200 rotates to cover a part of the main body base 100. The main body base 100 is provided with most switches related to the operation, such as the on-off switch 111. The switches are convenient to be installed at a portion that is always exposed even when the body cover 200 is covered. In addition, the lower fitting groove 115 and the upper fitting groove 215 on which the lower packing 320 and the upper packing 330 are detachably fitted are mounted on the upper surface of the main body base 100 and the lower surface of the main body cover 200, respectively. ) Is formed. These fitting grooves 115 and 215 are formed of tracks having an elliptical or rectangular shape corresponding to the shape of the lower packing 320 and the upper packing 330. The body cover 200 has a guide groove 211 (see FIG. 4) recessed in the left and right direction on an upper surface thereof. Referring to FIG. 2, the main body base 100 and the main body cover 200 are snap grooves 117 which are mutually snapped so that the main body cover 200 does not open when the main body cover 200 covers the main body base 100. ) And a snap protrusion 213 are provided. In addition, the main body base 100 is provided with an air outlet 113 to be connected when using an external vacuum pump.

The suction means 300 is composed of a suction nozzle 310, a vacuum pump (not shown), the lower packing 320 and the upper packing 330. The suction nozzle 310 is installed to be able to advance and retreat step by step toward the front from the body base 100. The suction nozzle 310 is advanced by the control lever 311 is installed on the upper surface of the body base 100 in a reciprocating direction. The vacuum pump (not shown) is installed inside the body base 100 and is connected to the suction nozzle 310 to provide a vacuum pressure (suction input) to the suction nozzle 310. The lower packing 320 and the upper packing 330 are loop-shaped members and are fitted into the lower fitting groove 115 and the upper fitting groove 215 formed in the main base 100 and the main cover 200, respectively. . When the lower packing 320 and the upper packing 330 is mounted on the main base 100 and the main cover 200, the lower chamber 325 and the upper chamber 335 which are spaces of a long shape left and right in the surrounding inner side thereof. ). These lower packing 320 and the upper packing 330 is the lower chamber 325 and the upper chamber 335 is joined while facing each other when the body cover 200 covers the upper surface of the body base 100 closed To form a confined space.

The sealing means 400 includes a heating bar 410 for generating high temperature heat and a compression packing 420 for pressing the heating bar 410. The heating bar 410 is installed in the horizontal direction while having a sufficient length for positioning the vacuum wrapping paper 90 therebetween with the pressing packing 420. The heating bar 410 operates differently in the automatic mode and the manual mode. That is, in the automatic mode, when the vacuum pressure inside the vacuum wrapping paper 90 reaches a predetermined set value, it operates to generate heat. In addition, it operates even if the operation switch 540 is pressed separately to generate heat. Meanwhile, in the manual mode, only the operation switch 540 is pressed to generate heat regardless of the vacuum pressure formed in the vacuum wrapping paper 90. In order to operate in the above-described automatic mode, a sensor (not shown) capable of measuring a vacuum pressure reaching a set value and a controller for operating the heating bar 410 in response to a signal transmitted from the sensor are not shown. May be installed inside the body base 100. Here, the controller is preferably configured to stop the operation of the vacuum pump (not shown) while operating the heating bar 410.

The pressing packing 420 is mounted to the lower portion of the lifting body 520 from the lower side of the main body cover 200 to protrude downward. According to such a configuration, when the main body cover 200 covers the main body base 100, the pressing packing 420 presses the heating bar 410. As a result, as soon as heat is generated in the heating bar 410 regardless of the automatic mode or the manual mode, the vacuum wrapping paper 90 located between the heating bar 410 and the compression packing 420 is heat-sealed and ready to be sealed. Here, in order to further press the compression packing 420 and the heating bar 410, the vacuum pressure is increased in the sealed space by the lower packing 320 and the upper packing 330, the main base 100 and the main cover ( 200 is more closely contacted, and will be described in detail later, but there is a method in which the push button 510 is directly pressed by the user.

The sealing means operating means 500 includes a push button 510, a lifting body 520, the pressing piece 530 consisting of a double pressing device and the operation switch 540. The push button 510 is formed in a long bar shape in the left and right direction and is accommodated and installed in a guide groove 211 formed above the main body cover 200. The push button 510 is maintained in a state of being raised in a normal state in which no external force is applied while receiving elastic force by the compression spring 511 provided between the guide groove 211 and the bottom surface 211A. On the lower surface of the push button 510, two kinds of protrusions protruding downward, that is, a pushing protrusion 513 and a pulling protrusion 515 are formed. Among them, the pushing protrusion 513 is provided with a pair on the left and right sides to maintain balance and protrudes downward with a clearance distance to the lifting body 520. As a result, the pushing protrusion 513 first moves the space of the play distance to an initial stage when the push button 510 is pressed. Subsequently, after the end of the pushing protrusion 513 passes through the main body cover 200, the support protrusion 523 of the lifting body 520 is contacted to push the lifting body 520 downward. . At this time, since the pushing protrusion 513 does not affect the lifting body 520 little while the space of the clearance distance is moved in the initial stage, the lifting body 520 does not move but only the push button 510 moves. Will be. As described above, when the push button 510 is pressed, only the push button 510 is lowered in the initial stage, and then the push button 510 and the lifting body 520 are lowered together in the next stage. Accordingly, the push button 510 can be lowered regardless of the state in which the lifting body 520 cannot be lowered, and thus various applications are possible. In particular, in the present embodiment, even when the lifting body 520 is difficult to move because the pressing packing 420 is pressing the heating bar 410 by the dual mechanism, the push button 510 and the pressing piece 530. Since the play distance can be freely moved, the operation switch 540 can be pressed at any time by the switch push pin 531 provided in the pressing piece 530. Here, the operation switch 540 serves to operate the heating bar 410, but can be applied by switching to a variety of other roles depending on the product. Meanwhile, the pulling protrusion 515 protrudes downward to penetrate the bottom surface of the guide groove 211 and then penetrate the lifting body 520 again. And the end is fastened to the head bolt 517 to pull up the lifting body 520 from the lower side is fastened. As a result, the pulling protrusion 515 serves to pull up and down the lifting body 520 at a clearance distance when the push button 510 is raised. As described above, the pulling protrusion 515 is formed at the bottom surface 211A of the guide groove 211 to connect the lifting body 520 positioned below the main body cover 200 and the push button 510 located above. Through the through hole 217.

The lifting and lowering body 520 is formed in a left and right direction, and has a compression packing fitting groove 521 at a lower portion thereof so that the compression packing 420 can be fitted and fixed.

The pressing piece 530 is coupled to ascend and descend with the push button 510 at the lower edge of the body cover 200. The pressing piece 530 is formed to be bent in the "L" shape corresponding to be installed in the corner of the main body cover 200, and has a switch pressing pin 531 protruding downward at one end thereof. As a result, the pressing piece 530 is lowered together when the push button 510 is pressed, and at this time, the switch pressing pin 531 is pressed to operate by pressing the operation switch 540 installed on the upper right side of the main body base 100. do.

By such a configuration, the sealing means operating means 500 operates the sealing means 400 at any time when the push button 510 is pressed in the automatic mode and the manual mode to seal the vacuum wrapping paper 90. The present invention can be freely performed when the sealing of the vacuum wrapping paper 90 is desired by providing the sealing means operating means 500 including such a double pressing device. That is, in the automatic mode in which the heating bar 410 operates according to the set vacuum pressure, the vacuum wrapping paper 90 may be sealed early by using the sealing means operating means 500 before the vacuum pressure reaches the set value. In addition, in the manual mode, the user can seal the vacuum wrapping paper 90 at an appropriate time according to the degree of vacuum. For reference, the manual mode is suitable for packing the contents at a higher vacuum pressure than the automatic mode. This is because, in the manual mode, unlike the automatic mode, the vacuum pump does not have to be excessively loaded, so there is no need to worry about the murmuring noise or vibration occurring every time, thereby making the most of the output of the vacuum pump. In addition, the present invention, unlike the conventional automatic vacuum packaging machine that had to operate the vacuum pump without a choice can be operated silently without the vacuum pump can not operate the vacuum pump when you want to seal the vacuum packaging without vacuum.

As such, the present invention can package the contents at an appropriate vacuum pressure in accordance with the strength and properties of the contents requiring packaging.

5 is a reference perspective view for explaining the operation of the suction nozzle according to the present invention.

As shown, the suction nozzle 310 according to the present invention can be installed in the body base 100 to be retractable to adjust the degree of protruding forward. That is, when the control lever 311 is moved to the first position 311A, the end of the suction nozzle 310 is positioned in the lower chamber 325 formed inside the lower packing 320 (310A). . In this case (310A) is mainly useful when using a vacuum wrapping paper embossed on the surface can be used as a general vacuum packaging without embossing.

Meanwhile, when the control lever 311 is moved to the second position 311B, the end of the suction nozzle 310 is positioned beyond the lower part of the lower chamber 325 or slightly beyond the line portion or line of the lower packing 320 ( 310B). This case 311B is mainly useful when using a vacuum wrapping paper in which embossing is not formed on the surface.

The operation of the vacuum packaging machine equipped with the double pressing device according to the present invention configured as described above will be described in detail by distinguishing the automatic mode from the manual mode. For this purpose reference is made to FIGS. 6A-6C together with the accompanying drawings mentioned above. 6A to 6C are a series of reference diagrams for explaining the operation of the dual pressing device of the present invention. (However, FIG. 6A is a case in which the vacuum cover is not applied when the body cover covers the body base. Is the case where the vacuum pressure is applied up to the set value, Figure 6c shows the case that the push button is pressed.)

First, the inlet end of the vacuum wrapping paper is placed in the lower chamber 325 surrounded by the lower packing 320 with the contents to be stored in the vacuum wrapping paper.

At this time, the suction nozzle 310 is inserted through the inlet of the vacuum wrapping paper and the end thereof is positioned in the lower chamber 325 surrounded by the lower packing 320 like the vacuum wrapping paper.

Thereafter, the body cover 200 is rotated to cover the body base 100. Then, the lower packing 320 and the upper packing 330 is in close contact with each other to form a closed space consisting of the lower chamber 325 and the upper chamber 335. At this time, the pressing packing 420 installed on the main body cover 200 is in a state of primarily pressing the heating bar 410 with the vacuum wrapping paper interposed therebetween.

Subsequently, when power is applied to the vacuum pump (not shown) by pressing the on / off switch 111 (see FIG. 2), the vacuum pump operates to suck air from the inside of the vacuum packing paper through the suction nozzle 310. . As a result, the vacuum pressure inside the vacuum packaging paper is gradually increased. In addition, while the vacuum pressure of the sealed space consisting of the upper chamber 335 and the lower chamber 325 is also increased equally, the lower packing 320 and the upper packing 330 are gradually compressed to cover the main body cover 200 with the main body base. It is in close contact with 100. At this time, the pressing packing 320 is to further press the heating bar 410. As described above, when the main body cover 200 is in close contact with the main body base 100, the double pressing device of the present invention is pressed as long as the push button 510 is not pressed as shown in FIG. 6A to FIG. 6B. The button 510 and the lifting body 520 are lowered together with the main body cover 200 while maintaining the clearance distance as it is. At this time, the switch push pin 531 is slightly lowered toward the operation switch 540, but the operation switch 540 is not pressed.

Then, when the vacuum pressure inside the vacuum wrapping paper or the sealed space reaches a preset value, a sensor (not shown) measures this and sends a signal to the controller (not shown). Then, the controller operates the heating bar 410 to generate high temperature heat in the heating bar 410. When the high temperature heat is generated in the heating bar 410 as described above, the vacuum packing paper is formed by heat-sealing the upper vinyl and the lower vinyl of the vacuum packing paper held by the pressure packing 420 with the strong bar between the heating bar 410. Sutured.

On the other hand, in the case of contents that are easily broken or damaged, it is preferable to seal early before the vacuum pressure inside the vacuum wrapping paper reaches a set value. To this end, it is only necessary to press the push button 510 protruding upward from the body cover 200 when the vacuum pressure inside the vacuum wrapping paper does not reach the set value. 6A to 6B, the push button 510 is pressed while the push button 510 and the lifting body 520 are lowered together while maintaining the clearance distance by the compression spring 511. will be. Then, the push button 510 initially moves the clearance distance from the lifting body 520, and thus the push piece 530 coupled to the push button 510 is lowered and the switch is pressed as shown in FIG. 6C. The pin 531 presses the operation switch 540. When the operation switch 540 is pressed, the heating bar 410 operates to generate heat. Next, when the main body cover 200 is not completely in contact with the main body base 100, the lifting body 520 is pressed and lowered by the push button 510. Then, the pressing packing 420 mounted below the lifting body 520 further presses the heating bar 410 to smoothly seal the vacuum wrapping paper sandwiched therebetween.

As described above, the present invention can seal the vacuum wrapping paper early in the configuration capable of operating the heating bar 410 by pressing the operation switch 540 early in the automatic mode.

On the other hand, in the manual mode, even if the vacuum pressure of the vacuum packaging machine reaches a set value, the heating bar 410 does not operate automatically. Therefore, in the manual board, the user must press the push button 510 to seal the vacuum wrapping paper. Hereinafter, the operation of the present invention in the manual mode will be described.

As in the automatic mode, the inlet end of the vacuum wrapping paper is placed in the lower chamber 325 formed inside the lower packing 320 with the contents to be stored in the vacuum wrapping paper (at this time, the suction according to the type of the vacuum wrapping paper) Adjust the exposed length of the nozzle 310 so that its tip is positioned in the lower chamber 325 surrounded by the lower packing 320 or on or off the line of the lower packing 320 outside the lower chamber 325. Can be positioned slightly off).

Thereafter, when power is applied to the vacuum pump by pressing the on / off switch 111, the suction nozzle 310 sucks air from the inside of the vacuum wrapping paper while the vacuum pump operates. As a result, the vacuum pressure inside the vacuum packaging paper is gradually increased.

At this time, the lower packing 320 and the upper packing 330 are compressed while the vacuum pressure of the sealed space including the upper chamber 335 and the lower chamber 325 is increased, so that the main body cover 200 is attached to the main body base 100. It gets closer. Then, the push button 510 and the lifting body 520 are lowered together while maintaining the clearance distance by the compression spring 511 as shown in Figure 6a to 6b.

Subsequently, when an appropriate degree of vacuum pressure is formed inside the vacuum wrapping paper, when the user judges this and presses the push button 510, the push piece 530 coupled to the push button 510 is lowered as shown in FIG. 6C. While the switch push pin 531 presses the operation switch 540. As a result, the heating bar 410 operates to generate heat. Next, the lifting body 520 is pushed down by the push button 510 and the pressure packing 420 mounted on the lifting body 520 is further pressed against the heating bar 410. As a result, the vacuum wrapping paper held therebetween is heat-sealed and sealed.

Subsequently, modified embodiments of the present invention will be described.

As shown, the modified embodiment of the present invention is characterized in that it does not include the suction nozzle 310 (refer to FIG. 2) compared to before the modification. Therefore, an inlet 327 is formed inside the lower chamber 325 surrounded by the lower packing 320 and connected to a vacuum pump (not shown) to suck air.

According to such a configuration, when the main body cover 200 covers the main body base 100, a vacuum pressure is formed in a closed space formed by combining the lower chamber 325 of the lower packing 320 and the upper chamber 335 of the upper packing 330. As it is formed, the air is sucked from the vacuum wrapping paper.

In this modified embodiment, since the suction nozzle 310 is omitted, the configuration has a simple advantage. However, since the configuration of the sealing means and the sealing means operating means, which are not mentioned, does not change as compared with before deformation, the automatic mode and the manual mode are possible, and in the automatic mode, the vacuum wrapping paper can be sealed early.

8 is a perspective view according to another modified embodiment of the present invention.

As shown, in another modified embodiment of the present invention, the lower packing (320, FIG. 2) and the upper packing (330, FIG. 2), which were provided with only the suction nozzle 310 and formed a closed space, as compared with before the deformation. Is not provided.

This modified embodiment also has the advantage that the configuration is simplified because the lower packing 320 and the upper packing 330 is omitted compared to before the modification. However, packings 329 and 339 replacing the same are installed in the body base 100 and the body cover 200, respectively.

The preferred embodiment of the present invention has been described above. The present invention may use various changes, modifications, and equivalents. It is clear that the present invention can be applied in the same manner by appropriately modifying the above embodiments. Accordingly, the above description does not limit the scope of the invention as defined by the limitations of the following claims.

As described above, the dual pressing device according to the present invention can be applied to a variety of products by the pressing structure that operates in a double, it is possible to implement a vacuum packaging machine that can be easily and automatically switched to suit the user's convenience. .

In addition, the vacuum packaging machine equipped with the double pressing device of the present invention can be sealed by properly adjusting the vacuum pressure according to the state of the contents even when operating in the automatic mode.

In addition, the vacuum packaging machine of the present invention can vacuum-pack various kinds of vacuum packaging paper with or without embossing.

In addition, since the vacuum packaging machine of the present invention can be operated in a manual mode, the vacuum packaging machine can be packaged by pulling up the vacuum pressure as much as possible in the automatic mode.

In addition, since the vacuum packaging machine of the present invention does not operate the vacuum pump when only sealing the vacuum wrapping paper without vacuum, it is possible to work quietly without noise.
