[0039] One side of the second gear 2205 is fixedly installed with a ratchet wheel 2206, the inner wall of the shell 2203 is fixedly installed with a supporting shell 2211, the inner wall of the supporting shell 2211 is rotatably connected with a ratchet pawl 2213, both sides of the ratchet pawl 2213 are fixedly installed with a rotating shaft 2212, one end of the rotating shaft 2212 penetrates to the outside of the supporting shell 2211, the ratchet wheel 2206 is used in cooperation with the ratchet pawl 2213, through the cooperation of the ratchet wheel 2206, the supporting shell 2211, the ratchet pawl 2213 and the rotating shaft 2212, when the ratchet pawl 2213 is clamped on the ratchet wheel 2206, the ratchet wheel 2206 is limited by the ratchet pawl 2213, so that the ratchet wheel 2206 can only rotate counterclockwise, and cannot rotate clockwise, thereby ensuring that the winding drum 2209 will not reverse after winding the film at one end, thereby ensuring the stability of fixing one end of the film.

[0040] The inner wall of the supporting shell 2211 is fixedly installed with a baffle 2210, one side of the baffle 2210 is in contact with one side of the ratchet pawl 2213, one side of the ratchet pawl 2213 is fixedly installed with a tension spring 2215, one end of the tension spring 2215 is fixedly installed with a mounting plate 2214, the top of the mounting plate 2214 is fixedly installed on the inner wall of the shell 2203, through the setting of the baffle 2210, the ratchet pawl 2213 can only rotate clockwise from the initial position, and cannot rotate counterclockwise, thereby ensuring the stability of fixing the ratchet wheel 2206, through the cooperation of the tension spring 2215 and the mounting plate 2214, the ratchet pawl 2213 can be reset after being pressed and rotated by the ratchet wheel 2206 each time, thereby ensuring the stability of fixing the ratchet wheel 2206.

[0041] One side of the ratchet wheel 2206 is fixedly installed with a rotating rod 2207, the surface of the rotating rod 2207 is fixedly installed with a bearing 2208, one side of the outer ring of the bearing 2208 is fixedly installed on the inner wall of the shell 2203, through the cooperation of the rotating rod 2207 and the bearing 2208, the ratchet wheel 2206, the second gear 2205 and the winding drum 2209 can be more stable during rotation, thereby ensuring stable fixing of one end of the film.

[0042] Through the cooperation of the transmission unit 21 and the fixing unit 22, the film can be guided and pulled. When the freshly produced film is guided and pulled, manual pulling is not required, and the film will not be wound incorrectly in the limiting rotating roller 12, the fixing roller 13 and the guide wheel set 14 during pulling, thereby ensuring stability and convenience during pulling.

[0043] The specific implementation of the embodiment is: when the user needs to pull the just-produced film onto the winding roller 301 for winding, first, the just-produced film will come out of the outlet of the casting device body 11, then move out a length, and then be placed on the surface of the winding drum 2209. At this time, the user starts the small air pump 2216 using the external control switch and the battery. The start of the small air pump 2216 generates suction through the main pipe 2217 and the auxiliary pipe 2218, so as to adsorb the film on the surface of the winding drum 2209. At this time, the user starts the motor 2107 using the external control switch and the power supply. The start of the motor 2107 drives the first gear 2108 to rotate. The rotation of the first gear 2108 rolls in the inner cavity of the guide plate 2104 through the meshing with the tooth groove 2109. The rolling of the first gear 2108 drives the motor 2107 to move. The movement of the motor 2107 drives the multiple extension rods 2106 to move. The movement of the multiple extension rods 2106 drives the fixed plate 2105 to move. The movement of the fixed plate 2105 drives the sliding sleeve 2103 to move on the surface of the sliding rod 2101. The movement of the multiple extension rods 2106 drives the connecting rod 2201 to move. The movement of the connecting rod 2201 drives the connecting plate 2202 to move. The movement of the connecting plate 2202 drives the shell 2203 to move. The movement of the shell 2203 drives the second gear 2205 to move on the surface of the tooth plate 2204. The meshing of the tooth plate 2204 and the second gear 2205 makes the second gear 2205 start to rotate. The rotation of the second gear 2205 drives the winding drum 2209 to rotate. The rotation of the winding drum 2209 winds and fixes the film. After the winding drum 2209 rolls for several turns, one end of the film is completely wound and fixed on the surface of the winding drum 2209. At this time, the second gear 2205 also disengages from the tooth plate 2204. The rotation of the second gear 2205 drives the ratchet wheel 2206 to rotate. The ratchet wheel 2206 rotates through the rotating rod 2207 and the bearing 2208. The counterclockwise rotation of the ratchet wheel 2206 will squeeze the pawl 2213. The squeezed pawl 2213 will rotate through the rotating shaft 2212 while pulling the tension spring 2215. After the second gear 2205 disengages from the tooth plate 2204, the second gear 2205 stops rotating. At the same time, the pawl 2213 will be clamped into the ratchet wheel 2206 through the counterforce of the tension spring 2215. The setting of the baffle 2210 makes the pawl 2213 only rotate in one direction at the initial position, but not in the other direction. After the pawl 2213 is clamped into the ratchet wheel 2206, the ratchet wheel 2206 can be positioned, and then the second gear 2205 can be positioned, and then the winding drum 2209 can be positioned. In the process of pulling the film, the winding drum 2209 will not be reversed, which ensures the stability of the film pulling. After one end of the film is wound and fixed on the surface of the winding drum 2209,The continuous rolling in the inner cavity of the guide plate 2104 is realized through the first gear 2108, and the telescopic property of the multiple telescopic rods 2106, so that the film can be pulled along the track of the guide plate 2104 until the film is moved to the inner cavity of the limiting groove 309, at this time, the user controls the limiting rotating roller 12 to move to the position in contact with the film through the electric slide rod 2101, so as to achieve the purpose of guiding and pulling the film. When the film just produced is guided and pulled, the operator does not need to pull by manpower, and meanwhile, it can also ensure that the film will not be wound in the limiting rotating roller 12, the fixed roller 13 and the guide wheel set 14 in the process of pulling, so as to ensure the stability and convenience in the process of pulling.
