[0001] This invention relates to the field of packaging facilities, and more particularly to a rolling vacuum packaging machine. Background Technology

[0002] Vacuum packaging machines can extract air from packaging bags and seal them after reaching a predetermined vacuum level. Vacuum packaging machines are often used in industries such as food. However, when performing the sealing operation, after the packaging bag is sealed, workers need to remove the packaging bag and place it in the work area for sealing. During the placement process, the packaging machine is mostly stopped. This operation prevents the packaging machine from running continuously, thus affecting work efficiency.

[0008] Preferably, a first inclined guide edge is provided at the lower rear edge of the upper support plate, a second inclined guide edge is provided at the upper rear edge of the lower support plate, an upper connecting frame is fixedly installed at the upper rear edge of the upper support plate, the end of the upper connecting frame is fixed to the end of the upper push frame, and a lower connecting frame is fixedly installed at the lower rear edge of the lower support plate, the end of the lower connecting frame is fixed to the end of the lower push frame.

[0009] Preferably, the upper and lower parts of the bearing seat are provided with bearing holes, the upper push frame and the lower push frame are respectively fitted into the two bearing holes, a connecting plate is fixedly installed between the front end of the upper push frame and the front end of the lower push frame, a return spring is wound around the outside of the upper push frame, the two ends of the return spring are respectively fixed to the rear end of the connecting plate and the front end of the bearing seat, a limiting plate is fitted into the rear end of the bearing seat, the limiting plate is embedded in the outer surface of the upper connecting frame and the outer surface of the lower connecting frame, and a lug extends from the middle of the upper end of the upper connecting frame.

[0010] Preferably, the top component includes a guide sleeve disposed on the side of the vacuum tube, a guide prism is installed through the inside of the guide sleeve, the guide prism is fitted with the guide sleeve, a push plate is fixedly installed on the outer surface of the guide prism near the lower edge, and a top seat is fixedly installed on the lower end face of the guide prism.

[0012] Compared with the prior art, the present invention has the following beneficial effects: 1. When the vacuum packaging machine is working and sealing, the packaging bag is clamped between the lower clamp and the upper clamp near the sealing position. After the previous packaging bag is sealed, the conveyor belt moves the sealed packaging bag away from the working area, and at the same time moves the clamped packaging bag to be sealed to the working area for sealing. This allows the sealing operation to continue, effectively improving work efficiency.

[0013] 2. Furthermore, under the action of the upper and lower support plates, the sealing area of ​​the packaging bag can be opened, allowing the vacuum tube on the vacuum packaging machine to be smoothly inserted into the packaging bag after the packaging bag is moved to the working area, thereby ensuring the normal operation of the vacuuming process.

[0014] 3. When the vacuum tube is moved forward and inserted into the packaging bag, the top seat will be moved forward synchronously by the vacuum tube. During the forward movement, when the top seat passes the lug, it will use its own inclined surface and the support of the lug to move upward to pass the lug, so that the plane of the top seat and the lug abuts. After the vacuum is completed, the vacuum tube will move backward to reset and detach from the packaging bag. During the backward movement, the top seat will push the abutting lug backward, thereby driving the lower support plate and the upper support plate to move backward synchronously to detach from the packaging bag, so that the sealing part of the packaging bag can be fully fitted and heated and sealed by the heating plate, thus ensuring the normal operation of the sealing operation.

The connecting plate 15 is used to hold the upper push frame 17... The lower push frame 16 is fixed together. The two ends of the return spring 14 are fixed to the rear end of the connecting plate 15 and the front end of the bearing seat 12, respectively. The rear end of the bearing seat 12 is fitted with a limit plate 26. The limit plate 26 limits the forward movement distance of the lower support plate 19 and the upper support plate 18. The limit plate 26 is embedded in the outer surface of the upper connecting frame 21 and the outer surface of the lower connecting frame 22. The upper middle part of the upper connecting frame 21 has a lug 20, which cooperates with the top seat 33.

[0024] The top component includes a guide sleeve 28 disposed on the side of the vacuum tube 34. A guide prism 30 is installed through the inside of the guide sleeve 28. The guide sleeve 28 and the guide prism 30 serve to vertically guide the top seat 33. The guide prism 30 fits into the guide sleeve 28.

The end of the fixing bracket 27 is fixed to the side of the vacuum tube 34.

[0026] During sealing, the upper clamp 4 is first pulled upwards, and then the packaging bag is clamped between the lower clamp 5 and the upper clamp 4 near the sealing position. At this time, the lower support plate 19 and the upper support plate 18 are located inside the packaging bag to open the sealing position of the packaging bag. Then, the conveyor belt 2 moves the clamped packaging bag to the working area, that is, moves the sealing position of the packaging bag between the two heating plates 35. Then, the vacuum tube 34 on the vacuum packaging machine body 1 moves forward and inserts into the packaging bag. At this time, the top seat 33 will be driven forward synchronously by the vacuum tube 34. During the forward movement, when the top seat 33 passes the lug 20, the top seat 33 will move upwards using its own inclined surface and under the support of the lug 20 to pass over the lug 20, so that the plane of the top seat 33 and the lug 20 abuts. Then, the two heating plates 3 5. The sealing plate 35 clamps the sealed end of the packaging bag between the two heating plates 35. At the same time, the vacuum tube 34 works to evacuate the packaging bag. After the vacuuming is completed, the vacuum tube 34 moves backward to reset and detach from the packaging bag. During the backward movement, the top seat 33 pushes the abutting lug 20 backward, which in turn drives the lower support plate 19 and the upper support plate 18 to move backward simultaneously to detach from the packaging bag. Then, the heating plate 35 works to heat and seal the packaging bag. After the sealing is completed, the two heating plates 35 separate, and the conveyor belt 2 moves to allow the sealed packaging bag to leave the working area. At this time, the lug 20 abutting the top seat 33 separates from the top seat 33 under the side movement, allowing the upper support plate 18 and the lower support plate 19 to reset. After the packaging bag is completely removed from the working area, the sealed packaging bag can be removed.
