Description

Automatic Vacuum Packaging Machinery

technical field

The utility model relates to the field of packaging machinery and equipment, in particular to a vacuum packaging machine.

Background technique

At present, general vacuum-packed products are usually vacuum-sealed and formed by a vacuum packaging machine to form a four-side heat-sealed flat bag-type vacuum package. This kind of packaging has the disadvantages of serious deformation of the packaging bag, many folds, easy leakage, poor sealing, complex manual operation in the actual production process, low production efficiency, and unfavorable for high-speed automatic production; while the traditional stretch film vacuum Packaging machines stretch the base film and then cover the cover film on it. Due to the limitation of the stretching depth of the stretching film, and if simply increasing the thickness of the stretching film to increase the stretching depth will make the film too hard, the packaging It is easy to puncture each other, so the existing stretch film packaging machines are only suitable for products with small packaging volume. For larger products, the form of stretch film vacuum packaging cannot be used.

Utility model content

In view of the above problems, the applicant has carried out research and improvement, and provides a continuous thermoforming vacuum packaging machine capable of packaging large-volume products such as zongzi by stretching the upper and lower films separately, replacing the traditional vacuum bag packaging form, and improving Improve production efficiency, reduce production costs, and reduce labor intensity of workers.

In order to solve the above problems, the utility model adopts the following scheme:

An automatic vacuum packaging machine, including a conveying device installed on a frame, a bag forming device, a vacuum heat sealing device and a die-cutting device arranged in sequence along the conveying direction of the conveying device, the conveying device includes a The transmission chain installed on the frame, the bottom film roll and the waste roll are installed on the frame at both ends of the transmission chain, the upper film roll is installed above the transmission chain through the bracket, and the bag forming device includes a bottom film mounted on the frame. The film thermoforming device and the upper film thermoforming device installed on the bracket are located at the rear end of the conveying direction of the vacuum heat sealing device: an incision device is installed at the junction of the bottom film and the upper film.

As a further improvement of the above technical solution:

The bottom film thermoforming device includes a bottom film preheating device and a bottom film former on the bottom film side, the bottom film former has a bottom film forming cavity; the upper film thermoforming device includes a The upper film preheating device and the upper film former have an upper film forming chamber on the upper film former.

The shape of the cavity opening of the bottom film forming cavity is completely consistent with the shape of the cavity opening of the upper film forming cavity.

The technical effect of the utility model is:

In the utility model, since the upper and lower films are stretched and formed at the same time, the volume of the molded cavity is larger when the thickness of the stretched film is kept constant, and products with larger volumes can be packaged, which improves the production capacity; The shape of the product sets the upper and lower parting surfaces, and the upper and lower forming molds are made according to the shape, which greatly reduces the degree of packaging wrinkles after vacuuming, making the packaging more beautiful.

detailed description

Below in conjunction with accompanying drawing, the specific embodiment of the present utility model will be further described.

As shown in Figure 1, the automatic vacuum packaging machine of this embodiment includes a conveying device installed on the frame 1, a bag forming device, a vacuum heat sealing device 12 and a die-cutting device arranged in sequence along the conveying direction of the conveying device 13. The conveying device includes a transmission chain 3 installed across the frame 1, the bottom film roll 2 and the waste roll 14 are installed on the frame 1 at both ends of the transmission chain 3, and the upper film roll 6 is installed on the transmission chain 3 through a bracket 9 Above, the bag forming device includes a bottom film thermoforming device installed on the frame 1 and an upper film thermoforming device installed on the support 9, located at the rear end of the conveying direction of the vacuum heat sealing device 12: the bottom film 11 and An incision device 10 is installed at the film joint of the upper film 15 .

The base film thermoforming device includes a base film preheating device 4 and a base film forming device 5 located on the base film side, and the base film forming device 5 has a base film forming cavity 51; the upper film thermoforming device includes an upper film forming device located on the upper film side The film preheating device 7 and the upper film forming device 8 have an upper film forming cavity 81 on the upper film forming device 8 . In order to ensure that the upper film and the bottom film form a complete accommodating cavity, the bottom film forming cavity 51 is completely consistent with the cavity of the upper film forming cavity 81; The shape of the mouth of the film forming cavity 81 is exactly the same, that is to say, it can ensure that the edges of the mouth of the upper film 15 and the bottom film 11 are completely overlapped when the films are combined after forming.

The working process of the present utility model is as follows:

The bottom film roll 2 is driven by the transmission chain 3 for precise step-by-step transmission. After being preheated by the bottom film preheating device 4, the bottom film former 5 vacuumizes and stretches the bottom film 11 into a specific cavity. After filling Filling at the station; the upper film roll 6 is also driven by the transmission chain 3, and after being preheated by the upper film preheating device 7, the upper film former 8 vacuumizes the upper film 15 to form a specific cavity The formed and filled base film 11 and upper film 15 are driven by the transmission chain 3, enter the vacuum heat sealing device 12 after the incision device 10 incision, and then enter the vacuum heat sealing device 12 for vacuum sealing. 13 Die-cutting is performed to form a packaged product, and the packaging work is completed.
