And the speed control block is tightly pressed and attached to the speed control wheel under the action of the second spring, so that the rotating speed of the film rolling roller can be prevented from being too high. And set up the inclined plane to the support frame up end, lay the roll up membrane roller on the support frame after, roll up the membrane roller and just can be under the effect of gravity towards supporting wheel direction roller, the installation of the roll up membrane roller of being convenient for.
Preferably, two sides of the wheel surface of the speed control wheel are fixedly connected with limiting side plates protruding outwards relative to the wheel surface, and the speed control block is located between the two limiting side plates. The setting of spacing curb plate can prevent that accuse fast piece from breaking away from accuse fast wheel.
Preferably, the upper end surface of the support frame is provided with a groove with a semicircular cross section, the groove penetrates through the left side and the right side of the support frame, and when the film rolling roller is arranged between the support wheel and the pressing wheel, a space allowance is reserved between the film rolling roller and the groove wall of the groove. The setting of recess can avoid rolling up membrane roller and support frame contact.
Preferably, the outer end of the support frame is fixedly connected with a stop block protruding upwards. The setting of dog can prevent to lay when rolling up the membrane roller that the membrane roller breaks away from the support frame.
Preferably, the side surface of the stopper facing the fixing plate is an inclined surface, and the angle between the inclined surface and the upper end surface of the support frame is 135 °.
Compared with the prior art, the utility model discloses following beneficial effect has: the utility model discloses an installation between roll up membrane roller and the bearing structure is very convenient, can simplify the installation of rolling up the membrane, and it is more convenient to operate. Simultaneously, can transversely spacing to rolling up the membrane roller, prevent to roll up the membrane roller and take place lateral shifting, can prevent to roll up the membrane roller rotational speed too fast through the cooperation of the fast piece of accuse speed wheel and the setting.
