Description

Technical Field

[0001] This invention belongs to the field of composite film production technology, specifically, it relates to a multilayer composite film production equipment with a cooling device. Background Technology

[0002] Composite films are multilayer film structures formed by dry lamination, extrusion lamination or co-extrusion of two or more different materials. They are widely used in food, pharmaceutical, electronics and industrial packaging and have comprehensive properties such as high barrier properties, heat resistance and puncture resistance. Currently, during the composite film production process, the film temperature is relatively high immediately after leaving the composite roller. At this time, the film is soft and has poor rigidity. Direct winding can easily cause compression deformation under tension, resulting in "plum blossom core" or transverse wrinkles. Moreover, at high temperatures, the adhesive is in a high creep state with weak initial adhesion. Under tension, the two substrate layers are prone to relative slippage, forming tunnels or bubbles, which affects the subsequent winding effect of the composite film. Based on this, we propose a multilayer composite film production equipment with a cooling device to solve the above problems. Summary of the Invention

A drive motor 51 is fixedly connected to the reducer 50, and the output end of the drive motor 51 is also fixedly connected to the power input end of the reducer 50.

The end of the guide arm 53 away from the support shaft 52 is rotatably connected to a tension roller 54. An electric push rod 55 is rotatably connected to one side of the support frame 48, and the output end of the electric push rod 55 is also rotatably connected to the guide arm 53. Working principle: First, the semiconductor cooling chip 34 and the electric heating wire 35 are activated. The cooling temperature generated by the semiconductor cooling chip 34 is introduced into the medium inside the liquid storage chamber A13 or the liquid storage chamber B14 through the temperature conducting block 33. The operation of the electric heating wire 35 raises the temperature of the medium inside the liquid storage chamber A13 or the liquid storage chamber B14. At the same time, the temperature inside the liquid storage chamber A13 and the liquid storage chamber B14 is monitored in real time by the temperature sensor 36 until the temperature of the medium inside the liquid storage chamber B14 is maintained at 18~25℃ and the temperature of the medium inside the liquid storage chamber A13 is maintained at 28~32℃. Then, the hydraulic cylinder 46 is activated to adjust the position of the displacement plate 47. With the connection between the displacement plate 47 and the linkage through groove 44, during the adjustment of the displacement plate 47, the assembly rod 38 can drive the eccentric plate 39 to rotate. Then, with the adaptive adjustment of the eccentric plate 39 inside the guide seat 41, the positioning frame 40 is moved, changing the distance between the sealing discs 10 until the distance between the sealing discs 10 is adapted to the width of the composite film. Simultaneously, the cryogenic transfer pump 15 is started to extract the cryogenic medium inside the storage chamber B14 through the external inlet pipe A16, and then through the transfer pipe A17 to the diversion pipe A19. After being diverted by the supply pipe A20, the cryogenic medium is transferred into the cryogenic chamber 11 through the guide rod 9, which reduces the temperature of the working area of ​​the temperature control cylinder 4. The medium then flows through another guide rod 9 to the return pipe A21 and finally returns to the storage chamber B14, realizing the circulation of the medium. The high-temperature transfer pump 22 is restarted to extract the high-temperature medium inside the storage chamber A13 through the external inlet pipe B23 and inject it into the guide pipe 26 through the transfer pipe B24. As the medium flows inside the guide pipe 26, it will be injected into the high-temperature chamber 12 through the transmission pipe 29 and the supply pipe B30. Then it will flow out through the outlet pipe 6 and the recovery pipe 32, and finally return to the storage chamber A13 through the return pipe B31, thus realizing the circulation of the medium. When cooling the composite film, the composite film is passed through the gap between the temperature control cylinders 4. When the composite film comes into contact with the working area of ​​the temperature control cylinder 4, it can exchange heat with the temperature control cylinder 4 to achieve efficient cooling. Since the temperature inside the high temperature chamber 12 is higher than the temperature inside the low temperature chamber 11, the surface temperature of the non-working area of ​​the temperature control cylinder 4 can always be higher than the ambient dew point, thereby avoiding condensation. The cooled composite film is then connected to the take-up roller 49. The drive motor 51 is then started, and the power of the drive motor 51 is transmitted to the take-up roller 49 through the reducer 50. The composite film is wound onto the take-up roller 49. At the same time, the electric push rod 55 can be started to push the guide arm 53, causing the guide arm 53 to rotate under the support of the support shaft 52, thereby changing the position of the tension roller 54. As the tension roller 54 is adjusted, the tension of the composite film during winding is changed.
