However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments of the following disclosure.

[0023] Embodiment 1, as Figure 1-Figure 4As shown, the utility model provides a vacuum packaging machine for dehydrated vegetables, comprising: a workbench 17, sliding grooves 10 are provided on the outer surfaces of both sides of the workbench 17, a motor 8 is fixedly connected to the inner wall of one side of the sliding groove 10, a threaded rod 9 is fixedly connected to the output end of the motor 8, a moving block 4 is threadedly connected to the outer surface of the threaded rod 9, a sliding rod 18 is fixedly connected to the inner surface of the other sliding groove 10, an auxiliary block 19 is movably connected to the outer surface of the sliding rod 18, the tops of the moving block 4 and the auxiliary block 19 are fixedly connected to the first electric push rod 5, the tops of the two first electric push rods 5 are fixedly connected to the connecting block 6, a sealing cover 7 is fixedly connected between the outer surfaces of the two connecting blocks 6, and the outer surface of the workbench 17 is fixedly connected to the outer surface of the workbench 17. The surface is fixedly connected with a controller 3, the outer surfaces of the moving block 4 and the auxiliary block 19 are slidably arranged with the inner surfaces of the two sliding grooves 10 respectively, a sealing strip 16 is arranged at the bottom of the sealing cover 7, and a first heat sealing strip 11 is symmetrically arranged on the top of the workbench 17, a plurality of second electric push rods 15 are fixedly connected to the inner top of the sealing cover 7, the plurality of second electric push rods 15 are divided into two groups, the bottoms of the two groups of second electric push rods 15 are fixedly connected with a second heat sealing strip 14, the positions of the two second heat sealing strips 14 are matched with the positions of the two first heat sealing strips 11, a vacuum pump 1 is fixedly connected to the inner bottom of the workbench 17, one end of the vacuum pump 1 is fixedly connected with a connecting pipe 2, and the end of the connecting pipe 2 away from the vacuum pump 1 is connected to the sealing cover 7.

[0024] The effect achieved by the entire embodiment 1 is that, when vacuum packaging the dehydrated vegetables, the packaging bag containing the dehydrated vegetables is placed on the workbench 17, and the packaging port is placed on the first heat sealing strip 11. When the placement is completed, the output ends of the two first electric push rods 5 are started to retract inward, driving the sealing cover 7 to move downward until it fits with the top of the workbench 17, and the sealing strip 16 is squeezed to fill the gap at the connection between the sealing cover 7 and the workbench 17 to ensure the sealing of the inner wall of the sealing cover 7. Then, the vacuum pump 1 is started through the controller 3, and with the cooperation of the connecting pipe 2, the inner wall of the sealing cover 7 is formed into a vacuum state. The pressure gauge on the top of the sealing cover 7 can observe the vacuum degree of the inner wall in real time, and then the two groups of second electric push rods 15 are controlled to move downward in turn through the controller 3, driving the two second heat sealing strips 14 to move downward in turn, and cooperate with the first heat sealing strip 14 to seal the inner wall of the sealing cover 7. 11 is used to seal the packaging bag twice, which ensures the sealing effect of the packaging bag. After the sealing is completed, the output ends of the two first electric push rods 5 are started to extend outward to move the sealing cover 7 upward, and then the threaded rod 9 is driven to rotate in the sliding groove 10 by the driving motor 8, so that the moving block 4 moves along the threaded rod 9, and with the cooperation of the auxiliary block 19, the sliding rod 18 and another moving block 4, the sealing cover 7 is moved on the workbench 17 to move to another packaging point for packaging. When the moving block 4 is moving, the controller 3 can be used in conjunction with the high-precision sensor to adjust the operating state of the motor 8 in real time to ensure the accurate movement of the moving block 4, so that the sealing cover 7 is accurately moved to the packaging point. By automatically adjusting the position of the sealing cover 7, the operation workload and complexity of the staff are reduced, and the packaging efficiency is improved.

[0025] Embodiment 2, as Figure 1-Figure 4 As shown, a plurality of adjustment grooves 13 are provided on the top of the workbench 17 near the two first heat sealing strips 11, and partitions 12 are inserted into the inner surfaces of the plurality of adjustment grooves 13. The first electric push rod 5, the second electric push rod 15, the motor 8 and the vacuum pump 1 are all electrically connected to the controller 3.

[0026] The effect achieved by the entire embodiment 2 is that when a packaging bag containing vegetables is placed on the workbench 17, the packaging bag can be positioned by setting the partition 12, and when different packaging bags are sealed, the partition 12 can be pulled out from the adjustment groove 13 and inserted into the adjustment groove 13 at different positions according to the size of the packaging bag, so as to adapt to the positioning of packaging bags of different sizes, facilitate the sealing work of the packaging bags, and is highly practical.

[0027] Working principle: When in use, the size of the packaging bag is adjusted to the position of the partition 12, and then the packaging bag is placed between the two partitions 12, and the packaging port is placed on the first heat sealing strip 11. When the placement is completed, the output ends of the two first electric push rods 5 are started to retract inward, driving the sealing cover 7 to move downward until it fits with the top of the workbench 17, and the sealing strip 16 is squeezed to fill the gap at the connection between the sealing cover 7 and the workbench 17 to ensure the sealing of the inner wall of the sealing cover 7. Then, the vacuum pump 1 is started through the controller 3, and with the cooperation of the connecting pipe 2, the inner wall of the sealing cover 7 is in a vacuum state. The pressure gauge on the top of the sealing cover 7 can observe the vacuum degree of the inner wall in real time, and then the two groups of second electric push rods are controlled in sequence through the controller 3. The rod 15 moves downward, driving the two second heat sealing strips 14 to move downward in sequence, and cooperate with the first heat sealing strip 11 to seal the packaging bag twice, ensuring the sealing effect of the packaging bag. When the sealing is completed, the output ends of the two first electric push rods 5 are started to extend outward, so that the sealing cover 7 moves upward, and then the driving motor 8 is used to drive the threaded rod 9 to rotate in the sliding groove 10, so that the moving block 4 moves along the threaded rod 9, and with the cooperation of the auxiliary block 19 and another moving block 4, the sealing cover 7 is moved on the workbench 17 to move it to another packaging point for packaging. By automatically adjusting the position of the sealing cover 7, the operation workload and complexity of the staff are reduced, and the packaging efficiency is improved.

[0028] The wiring diagram of the first electric push rod 5, the second electric push rod 15, the motor 8, the vacuum pump 1, the first heat sealing strip 11, the second heat sealing strip 14 and the controller 3 in the present invention is common knowledge in the field, and its working principle is a well-known technology. The model is selected according to the actual use. Therefore, the control method and wiring arrangement of the first electric push rod 5, the second electric push rod 15, the motor 8, the vacuum pump 1, the first heat sealing strip 11, the second heat sealing strip 14 and the controller 3 are no longer explained in detail.
