Description

Technical Field

[0001] The utility model relates to the technical field of packaging machines, in particular to a stretch film packaging machine with a vacuum acceleration device. Background Art

[0002] The stretch film packaging machine with vacuum acceleration device is an advanced packaging equipment widely used in fields such as food, medicine and electronic products. Its key features include vacuum extraction, stretch film technology, automated operation, acceleration device and versatility. The working principle involves feeding, stretch film preparation, vacuum extraction, film stretching and sealing, and finished product output. Its main advantages are to improve packaging efficiency, extend the shelf life of products, and ensure the freshness and quality of products.

[0003] After searching, the stretch film packaging machine with a vacuum acceleration device of announcement number CN220333063U includes: a vacuum heat sealing area, a vacuum chamber is provided inside the vacuum heat sealing area, a suction port is welded on one side of the vacuum heat sealing area, the other end of the suction port is connected to a filter through a pipe, the outlet of the filter is connected to a tee through a pipe, a first valve is provided on the connecting pipe between the tee and the filter, one end of the tee is connected to a vacuum pump through a pipe, a second valve is provided on the connecting pipe between the vacuum pump and the tee, the other end of the tee is connected to a vacuum tank through a pipe, a third valve is provided on the connecting pipe between the vacuum tank and the tee, and a sewage outlet is welded on one end of the vacuum tank. This solves the problem that when the existing vacuum acceleration device is combined with the stretch film packaging machine, because some food carries liquids such as soup and water, these liquids easily enter the vacuum tank during vacuuming, causing the volume of the vacuum tank to decrease.

[0004] Based on the above patent, by setting a filter, it is convenient to intercept the liquid drawn into the pipeline in the filter during vacuuming, so that the liquid is not easy to enter the vacuum tank, so as to ensure that the vacuum tank has sufficient volume, and thus ensure that the vacuum tank has a good vacuuming effect on the vacuum chamber. By setting a sewage outlet and a fourth valve, it is convenient to discharge sewage from the vacuum tank, so as to ensure that the vacuum tank has sufficient volume, and thus ensure that the vacuum tank has a good vacuuming effect on the vacuum chamber. However, in this device, when vacuuming the packaging bag, it is inconvenient to fix the packaging bag for vacuuming. If the packaging bag moves or fails to be fixed during the vacuuming process, it may cause the seal to be loose, thereby affecting the vacuum effect and thus affecting the shelf life of the product.

Tube 9, the outer wall of the right end of the workbench 1 is connected to the material table 10 through the material assembly, and the vacuum pump 2 is connected to the vacuum tank 3 through the tee pipe 9 to generate negative pressure in the suction and pressing table 4, thereby suctioning and pressing the packaging bag at the material table 10, and when the electric lifting rod 7 is raised and lowered, the extrusion wheel 8 squeezes the packaging bag for correction and fixation. The right end of the tee pipe 9 is fixedly connected to the left end of the vacuum tank 3, and the top of the tee pipe 9 is fixedly connected to the bottom end of the workbench 1 and passes through it. The outer walls of the front and rear ends of the extrusion wheel 8 are slidably connected to the inner wall of the fixed frame 6, and the outer wall of the bottom end of the extrusion wheel 8 is tightly attached to the outer wall of the top of the workbench 1.

[0028] Specifically:

[0029] Reference Figure 2 、 Figure 3 and Figure 4The inner wall of the butt joint 5 is fixedly connected to a fixed tube 11, and the front and rear ends of the fixed tube 11 are fixedly connected to a fixed rod 12.

The upper and lower ends of the outer wall of the toggle rod 14 are rotatably connected to a traction plate 15, and the opposite end of the traction plate 15 is rotatably connected to a clamping plate 16. After the packaging bag is put into the fixed tube 11 in the butt joint 5, the toggle rod 14 is released, so that the toggle rod 14 allows the return spring 13 to move the toggle rod 14 through the elastic force, so that the toggle rod 14 passes through the traction plate 15 and allows the clamping plate 16 to move to the fixed tube 11. The packaging bag is tightly attached to the fixed tube 11, and the right end of the return spring 13 is fixedly connected to the outer wall of the right end of the fixed rod 12, and the left end of the return spring 13 is fixedly connected to the right end of the toggle rod 14.

The tightness of the packaging is improved, the overall quality of the packaging is improved, the effect of vacuum packaging is improved, and the shelf life of the product is extended. When replacing the packaging bag material roll, the threaded rod 17 is rotated to make the adapter ring 18 pull the support plate 20 to shrink under the cooperation of the second connecting plate 21, so that the material roll at the second connecting plate 21 falls off, and the new material roll is installed on the second connecting plate 21. The threaded rod 17 is rotated in the opposite direction to make the second connecting plate 21 open to both sides, so as to facilitate the fixation of the material roll.
