Detailed Description
In order to make the objects, technical solutions and effects of the present invention clearer and clearer, the present invention is further described in detail below with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described herein are merely illustrative of the utility model and are not intended to limit the utility model.
Referring to fig. 1 and 2, the present invention discloses a casting film winding apparatus, including: the winding device comprises a winding roller 1, mounting brackets 2 mounted on two sides of the winding roller 1, a material breaking assembly 3 with two ends fixed on the mounting brackets 2, a transmission chain wheel 4 mounted on the mounting brackets 2, a driving device 5 connected with the transmission chain wheel 4 through a chain, and a winding shaft 6 mounted on the winding roller 1; the driving device 5 drives the mounting bracket 2 to rotate through the transmission chain wheel 4, so that the material breaking assembly 3 is close to the winding shaft 6.
A winding rubber pressing roller 7 is installed on one side of the winding roller 1, a casting film passes through the winding rubber pressing roller 7 and the winding roller 1 and is conveyed to the winding shaft 6, and the material breaking assembly 3 is close to the winding shaft 6 and cuts off the casting film between the winding shaft 6 and the winding roller 1.
After a casting film is produced and formed, the casting film is firstly conveyed to a winding roller 1 for preparation winding under the clamping friction of a winding rubber-pressing roller 7 and the winding roller 1, the winding rubber-pressing roller 7 presses the casting film to be close to the winding roller 1, and then the casting film is conveyed to a winding shaft 6 for winding. After the rolling is completed, the driving device 5 drives the mounting bracket 2 to rotate, and the material breaking assembly 3 is close to the rolling shaft 6 to cut off the casting film and complete the rolling. The material cutting assembly 3 is provided with a blade for cutting the casting film, and in an achievable embodiment of the utility model, the material cutting assembly 3 further comprises an electrostatic generator for transmitting static electricity to the casting film after material cutting, so that the casting film can be attached to a new winding shaft 6 conveniently.
One side of curtain coating membrane coiling mechanism still is provided with the chill roll 8 that is used for cooling the curtain coating membrane, and the curtain coating membrane process 8 back transport extremely wind-up roll 1 with rolling moulding-rubber roll 7.
