DETAILED DESCRIPTION

[0027] The present invention is further described below in conjunction with the accompanying drawings and embodiments. The present invention includes but is not limited to the following embodiments.

[0028] Embodiment 1:

[0029] like Figure 1-6As shown, the vacuum packaging device for pig blood balls provided by the utility model comprises: a box body 1, an exhaust mechanism is installed in the box body 1, and the air in the operating room 2 is extracted by the exhaust mechanism. Two operating rooms 2 are arranged in the box body 1, and a support plate 3 and a sealing ring 4 are installed in the operating room 2. A double-sided cover plate 5 is rotatably installed between the two operating rooms 2. Both sides of the double-sided cover plate 5 are provided with hot pressing rods 6. An electric heating device is arranged inside the hot pressing rods to keep the hot pressing rods 6 at a certain temperature. The double-sided cover plate 5 is fixedly installed with a heating rod 6. There are two mounting tubes 7, in which a sliding rod 8 is installed in a sliding seal, and both ends of the sliding rod 8 extend out of the mounting tube 7 and are fixedly connected to the hot pressing rod 6. A limiting plate 9 is fixedly installed in the middle of the sliding rod 8, and two springs 10 are arranged on both sides of the limiting plate 9. The spring 10 is sleeved on the sliding rod 8, and its two ends are respectively in contact with the limiting plate 9 and the inner wall of the mounting tube 7. When in use, the packaging bag filled with pig blood balls is placed flat on the supporting plate 3, and the double-sided cover plate 5 is turned over and covered on the top of the operating room 2, so that The double-sided cover plate 5 contacts the sealing gasket on the top of the sealing ring 4, and the air in the operating chamber 2 is extracted through the exhaust mechanism, so that the air in the operating chamber 2 is gradually reduced, and then the air in the package is gradually discharged, so as to achieve a near vacuum state in the packaging bag. At the same time, as the negative pressure in the operating chamber 2 increases, under the action of atmospheric pressure, the sliding rod 8 moves downward, and then compresses the spring 10 under the limit plate 9. The sliding rod 8 descends to make the hot pressing rod 6 gradually approach the bag opening of the packaging bag until the operating chamber 2 is close to vacuum, and the hot pressing rod 6 is tightly pressed at the bag opening of the packaging bag. After a period of time, as the contact time increases, the bag opening of the packaging bag gradually melts, and then the packaging bag is sealed. Then air is re-introduced into the operating chamber 2, and the double-sided cover plate 5 can be opened (and covered on the top of the operating chamber 2 on the other side where the packaging bag has been placed) and the sealed and packaged packaging bag can be taken out. When the vacuum operation is performed on the operating chamber 2 on one side, the packaging bag can be placed on the operating chamber 2 on the other side. When the packaging bag on one side is taken out, the operating chamber on the other side can be vacuumed at the same time.

[0030] By installing a hot pressing rod 6 on the double-sided cover plate 5, and by installing a tube 7, a sliding rod 8, a limiting plate 9 and a spring 10, the hot pressing rod 6 can be lowered as the air in the operating chamber 2 decreases until the operating chamber 2 is close to a vacuum. The hot pressing rod 6 presses the packaging bag for a period of time to seal the bag opening of the packaging bag. The device can seal the bag opening while evacuating the vacuum, thereby preventing the possibility of air re-entering the packaging bag.

[0031] Embodiment 2:

[0032] like Figure 3 As shown, handles 11 are fixedly installed on both sides of the double-sided cover 5, and anti-slip sleeves are installed on the handles 11. When in use, the double-sided cover 5 can be pulled open by the handles 11 located on the outside, thereby opening the operating room 2.

[0033] By fixing the handles 11 on both sides of the double-sided cover plate 5 , the double-sided cover plate 5 can be easily opened.

[0034] Embodiment 3:

[0035] like Figure 5 As shown, a mounting seam 13 is opened on the top of the support plate 3, and a positioning strip 12 is installed on the top of the support plate 3. When in use, the bag opening of the packaging bag is placed toward the mounting seam 13, and the bag opening is passed over the top of the positioning strip 12 and laid flat on the mounting seam 13. When air is extracted from the operating room 2, the air above the support plate 3 enters below through the mounting seam 13, and then pushes the lower layer of the bag opening to be adsorbed on the mounting seam 13, and then the hot pressing rod 6 descends and presses on the positioning strip 12 to perform hot pressing and sealing on the bag opening of the packaging bag.

[0036] By providing the positioning strip 12 and the installation seam 13, it is convenient to determine the placement position and orientation of the packaging bag, which is conducive to making the sealing position of the bag opening of the packaging bag more consistent.

[0037] Embodiment 4:

[0038] like Figure 2 As shown, the vacuum mechanism includes an air pump 14 installed in the box body 1, and an air inlet pipe 15 and an air outlet pipe 17 are installed on the air pump 14. The air inlet pipe 15 is Y-shaped, and its two ends extend into the two operating chambers 2 respectively, and one end of the air outlet pipe 17 extends out of the box body 1. Two valves 16 are installed on the air inlet pipe 15, and the two valves 16 respectively control the air intake at both ends of the air inlet pipe 15. When in use, the air pump 14 is started, and the valve 16 in the operating chamber 2 on the side that needs to be vacuumed is energized (the valve 16 on the other side is not energized). The valve 16 is energized to make the port of the air inlet pipe 15 on this side unblocked, and then the vacuum pump 14 is used to vacuum the operating chamber 2, and the extracted gas is discharged through the exhaust pipe 17.

[0039] By providing an air extraction mechanism including an air extraction pump 14, a Y-shaped air inlet pipe 15, a valve 16 and an air outlet pipe 17, the air in the two operating chambers 2 can be extracted alternately by one air extraction pump 14, which is more convenient to use.

[0040] Embodiment 5:

[0041] like Figure 1As shown, two operating switches 18 and a start-stop switch 19 are installed on one side of the box body 1, and the two operating switches 18 are interlocked, that is, when one operating switch 18 is closed, the other operating switch 18 is disconnected, the operating switch 18 is connected to the valve 16, and the start-stop switch 19 is connected to the vacuum pump 14. When in use, pressing the operating switch 18 on the same side as the operating room 2 can energize the valve 16 on this side (the valve 16 on the other side is de-energized), and then pressing the start-stop switch 19 can energize the vacuum pump 14.

[0042] By providing two interlocking operating switches 18 and a start-stop switch 19, the on and off of the valve 16 and the air pump 14 can be conveniently controlled.

[0043] Embodiment 6:

[0044] like Figure 1 As shown, a barometer 20 is installed on one side of the box body 1, and the barometer 20 is connected to the air inlet pipe 15. The air pressure in the air inlet pipe 15 is measured by the barometer 20, and then the air pressure in the operating room 2 can be measured, so that the vacuum pump 14 can stop working at the appropriate time.

[0045] By installing a barometer 20 on one side of the box body 1 , the air pressure in the operating room 2 can be conveniently measured.

[0046] Working principle: When in use, place the packaging bag filled with pig blood meatballs flat on the support plate 3, turn over the double-sided cover plate 5 and cover the top of the operating chamber 2, so that the double-sided cover plate 5 is in contact with the sealing gasket on the top of the sealing ring 4, and the air in the operating chamber 2 is extracted through the exhaust mechanism, so that the air in the operating chamber 2 is gradually reduced, and then the air in the package is gradually discharged, so as to achieve a near vacuum state in the packaging bag. At the same time, as the negative pressure in the operating chamber 2 increases, under the action of atmospheric pressure, the sliding rod 8 moves downward, thereby compressing the spring 10 under the limit plate 9, and the sliding rod 8 descends to make the hot pressing rod 6 gradually approach the bag opening of the packaging bag. When the operating chamber 2 is nearly vacuum, the hot pressing rod 6 is pressed tightly against the bag opening of the packaging bag. After a period of time, as the contact time increases, the bag opening of the packaging bag gradually melts, thereby sealing the packaging bag. Then, air is introduced into the operating chamber 2 again, and the double-sided cover 5 can be opened (and covered on the top of the operating chamber 2 on the other side where the packaging bags have been placed). Then, the sealed packaging bags are taken out. When the operating chamber 2 on one side is being vacuumed, the packaging bags can be placed on the operating chamber 2 on the other side. Correspondingly, when the packaging bags on one side are taken out, the operating chamber on the other side can be vacuumed at the same time.
