[0002] The casing film is a packaging material with very good barrier properties. It can effectively isolate oxygen and water vapor and improve the shelf life of the contents. The casing film will shrink at high temperatures and stick to the packaging. The packaging is very beautiful. It is mainly used to package ham sausages and can be used for industrial mass production of ham sausages on automatic sausage stuffers. The casing shrinking machine is a device used to shrink the casing film. When the casing shrinking machine shrinks the casing tubular film, the shrinking rod needs to penetrate the casing tubular film to support it.

The bottom of the installation side plate 43 is vertically fixed to the support base plate 42 as a whole. After the installation is completed, the first adsorption centering group 6 and the second adsorption centering group 7 are installed separately. Specifically, the meshing gear 63 can be installed by coaxial installation. On the rotating shaft 64, the rotating shaft 64 passes through the rotating bracket 61 and is hinged on the mounting side plate 43, and the rotating bracket 61 is connected to the side of the meshing gear 63 through a connecting pin, and the adsorption liner 62 is installed in the semicircular groove of the rotating bracket 61; an airflow channel 611 for vacuum negative pressure airflow is processed in the rotating bracket 61, and an arc-shaped adsorption channel 622 is processed on the adsorption liner 62, and the outer port of the airflow channel 611 is connected to the first connecting pipe 2 and the second connecting pipe 3; the inner ... The port is connected to the arc-shaped adsorption flow channel 622; finally, the opening and closing drive part 5 is installed. Specifically, the bottom of the support base 51 can be installed on the support base plate 42, the mounting end of the drive cylinder 52 is hinged to the support base 51, and the drive rod 53 is installed on the drive cylinder 52. One end of the connector 54 is installed at the outer end position of the drive rod 53, and one end of the connecting rod 55 is installed on the first adsorption centering group 6. The other end of the connecting rod 55 is hinged to the connecting head 54. At this point, the installation process of the utility model is completed;

[0027] During specific use, the operator can control the working motor 11 in the vacuum generating assembly 1 to start, and the working motor 11 can drive the vacuum pump group 13 to work, and the vacuum pump group 13 can generate (produce) vacuum negative pressure, because the vacuum pump group 13 is connected with the air flow channel 611 in the first adsorption centering group 6 and the second adsorption centering group 7 through the first external joint 14, the second external joint 15, the first connecting pipe 2, and the second connecting pipe 3.

At this time, under the action of the gear meshing force, the meshing gear 63 in the second adsorption and centering group 7 rotates counterclockwise. Since the rotating support arm 61 is connected to the side of the meshing gear 63 by a connecting pin, the rotating support arm 61 in the first adsorption and centering group 6 and the second adsorption and centering group 7 drives the adsorption liner 62 to approach and buckle together under the drive of the meshing gear 63. At this time, the adsorption liners 62 in the first adsorption and centering group 6 and the second adsorption and centering group 7 relatively form a "three-dimensional circular sleeve" structure. When the casing cylindrical film enters the "three-dimensional circular sleeve" (that is, the space between the two groups of adsorption liners 62), the vacuum negative pressure in the arc-shaped adsorption flow channel 622 in the adsorption liner 62 can adsorb and shape the outer periphery of the casing cylindrical film, thereby ensuring that the sleeve rod is accurately positioned at the center of the cylindrical film, thereby ensuring the subsequent sleeve shrinking operation process of the casing cylindrical film.
