The bottom end of the screw 11 is provided with a connector, the connector includes an outer tube 12 and an inner tube 13 arranged in the outer tube 12, the outer tube 12 and the screw 11 form a rotational fit connection, and the inner tube 13 extends to the inner side of the inner cavity of the screw 11, The outer pipe 12 is connected to the coolant inlet of the coolant storage tank 14 through a return pipe, and the coolant outlet of the coolant storage tank 14 is connected to the inner pipe 13 through a liquid discharge pipe, and a delivery pump and a solenoid valve are arranged on the liquid discharge pipe 15. The side wall of the coolant storage tank 14 is a sandwich structure, and cooling water is passed through the sandwich structure to cool down the coolant in the coolant storage tank 14 . During the extrusion process of the screw 11 extruder, the frictional shear heat generated by the rotation of the screw 11 is often more than the heat required by the material, which will cause the temperature of the material in the barrel to be too high. If the excessive heat is not discharged in time, it will Causes material (especially heat-sensitive plastics) to decompose and sometimes makes molding difficult. Therefore, the generated heat is taken out through the coolant, thereby avoiding excessive temperature of the screw 11 and ensuring production. Water may be used as the coolant, but water is likely to corrode the screw 11 as a cooling medium. Therefore, it is preferable to use a volatile coolant (such as mercury), which has no corrosion effect on the screw 11 and has a good cooling effect.

For the cooling device, it adopts the technical scheme shown in Figures 3 and 4 for implementation. The cooling device includes a cooling tank 21 and a cooling chamber 26 arranged in sequence.

The second tensioning mechanism includes a second tensioning roller. The two tension rollers are curved. Due to the large width of the film material, when the cooling air blows to the film material, it will cause the film material to vibrate greatly, resulting in the deviation of the film material. Therefore, the second tension roller is used to tension the film material to prevent Offset, to ensure reliable delivery of the entire conveyor line. The second tension roll can be obtained by bending an equidiametric axis. Through two-stage cooling, the cooling efficiency is improved and the bonding reliability between the metal foil and the polymer film layer is not affected. The film conveying rollers installed in the cooling tank and cooling chamber are not described in detail, and can be selected and installed according to needs.

The most preferred solution is that the angle between the third air injection pipe 33 and the horizontal plane is 45-60°.

Since the coiling of the coiler is intermittent at a faster speed, while other processes such as the pressing of the film are continuous at a slower speed, a temporary storage device is installed between the slitter and the coiler , to adjust the front and rear production.

The fourth adjustment mechanism adjusts the movable mounting frame 42 to move up and down, so that the distance between the fixed mounting frame 41 and the movable mounting frame 42 increases or decreases, thereby realizing temporary discharging and fast discharging, and ensuring the continuous production of the whole system. Since the film material needs to be cut off after a single operation of the coiler, in order to avoid the influence of film material shearing on the material storage mechanism, a pressing mechanism is set on the discharge side of the material storage mechanism to compress the film material , to prevent the membrane material from loosening on the conveying line. The fourth trough 44 is arranged along the width range of the membrane material, and the surfaces of the two groove walls on the fourth trough 44 which are in contact with the membrane material are arranged as arc-shaped surfaces, and the groove walls and the membrane material are in line contact. Line contact is the most reliable method for compressing the membrane material, which is better than surface contact. The fourth cylinder 45 can be arranged at intervals along the length range of the fourth groove-shaped member 44 .

Since the storage mechanism adjusts the front and rear processes, the conveying speed of the membrane material needs to be constantly changed, so it is prone to slack, which will cause the membrane material to shift and affect the entire production.
