Detailed Embodiments

[0018] The following describes the embodiments of the present utility model with reference to the drawings.

Triangular rib plates for reinforcement are connected to the installation table 1. A two-way hydraulic cylinder 2 is installed on the installation table 1. Moving frames 3 are connected to both the front and rear telescopic ends of the two-way hydraulic cylinder 2. The upper parts of the moving frames 3 are all C-shaped structures. The moving frames 3 and the installation table 1 are both connected in a sliding manner. An adsorption component 4 is installed on the moving frames 3. Three adjusting components 5 are installed on the adsorption component 4. The adjusting component 5 includes a positioning plate 51. Three positioning plates 51 are connected to the adsorption component 4 in a sliding manner. Adjusting screw rods 52 are all connected to the positioning plates 51 in a threaded manner. Anti-slip patterns are provided on the adjusting screw rods 52. The adjusting screw rods 52 and the adsorption component 4 are both connected in a rotational manner. A cold shrinking mechanism 6 is arranged on the moving frames 3. The cold shrinking mechanism 6 includes a fixed ring 61. The fixed ring 61 is connected to the moving frames 3. A driving motor 62 is installed on the fixed ring 61. A gear 63 is connected to the output shaft of the driving motor 62. Refrigeration components 64 are all installed on the fixed ring 61. The refrigeration component 64 includes an installation frame, a rack, an electric push rod, and a refrigeration element. Installation frames are all connected to the moving frames 3 in a rotational manner. Electric push rods are installed on the installation frames. The refrigeration element is connected to the telescopic end of the electric push rod. The inner sides of the refrigeration elements are all arc-shaped structures that fit the sheathing. Racks are all connected to the outside of the installation frames. The racks are meshed with the adjacent gears 63.

[0020] As Figure 1 and Figure 4 shown, it further includes a discharging mechanism 7. The discharging mechanism 7 includes an installation seat 71. Installation seats 71 are installed on both the front and rear parts of the installation table 1. A driving motor 72 is installed on the installation seat 71. Poking rods 73 are all connected to the output shaft of the driving motor 72.

[0021] It should be noted that plastic film is a widely used material with the characteristics of being light, transparent, waterproof, and having good barrier properties. In the production process of plastic film, it is necessary to perform sheath treatment on both ends of the plastic film to avoid problems such as looseness and deformation of the plastic film. The plastic film is wound on a reel and pressed with a sheath to ensure that the film is neatly and tightly arranged during the winding process, which can improve the quality and use effect of the film. First, the sheath is adsorbed using the adsorption component 4, and then the plastic film is placed on the mounting table 1, and the sheath is centered by adjusting the adjustment component 5, and the adjustment screw 52 is rotated to make the positioning plate 51 move and contact the sheath, and then the sheath is adjusted to a suitable position, and then the two-way hydraulic cylinder 2 is turned on to make the telescopic end of the two-way hydraulic cylinder 2 move unilaterally, which will drive the adjacent moving frame 3 inward. The sheath is moved sideways, thereby setting the sheath on one end of the plastic film. To prevent the sheath from slipping, the drive motor 62 is turned on, and the output shaft of the drive motor 62 rotates to drive the gear 63 to rotate, thereby driving the rack and the mounting frame to rotate successively, and at the same time, the electric push rod is turned on, and the telescopic end of the electric push rod will drive the refrigeration parts to perform refrigeration plastic sealing on the surface of the sheath. The rotation of the mounting frame will drive the refrigeration parts to perform refrigeration plastic sealing on the sheath, making the plastic sealing more uniform, thereby improving the plastic sealing effect. After completing the sheath and plastic sealing treatment on one side, the two-way hydraulic cylinder 2 is used to drive the telescopic end on the other side to press the sheath on the other side of the plastic film, and then the drive motor 72 can be used to drive the lever 73 to rotate outward, so that the lever 73 is separated from the locking and fixation of the plastic film, thereby facilitating rapid discharge, which helps to improve the efficiency of plastic film sheath pressing.
