Specifically, referring to fig. 7, the first base C1 includes a first bottom plate C11 fixedly disposed on the ground, and a third adjusting plate C12 disposed on an upper end surface of the first bottom plate C11, and the speed reducer C2 is fixedly disposed on the third adjusting plate C12; the third adjusting plates C12 are provided with at least two fifth waist-shaped holes C13 arranged in parallel, the first bottom plate C11 is provided with fourth locking screw holes (not visible in the figure) corresponding to the positions of the fifth waist-shaped holes C13, each third adjusting plate passes through one fourth locking screw C14, and the end parts of the fourth locking screws C14 are screwed into the corresponding fourth locking screw holes. When the position of the connecting seat C5 needs to be adjusted, the fourth locking screw C14 is only required to be loosened, then the distance between the third adjusting plate C12 and the swing frame A is finely adjusted, the connecting seat C5 is better connected with the swing frame A, and finally the fourth locking screw C14 is locked to complete adjustment.
Further, referring to fig. 7, the support plate C6 includes an L-shaped reinforcing plate composed of a transverse plate C61 and a vertical plate C62, the transverse plate C61 is connected with the third adjusting plate C12 by screws, the vertical plate C62 is disposed between the transmission gear C42 and the speed reducer C2, a avoiding hole (not visible in the figure) for the output shaft C21 of the speed reducer to pass through is formed in the vertical plate C62, and the speed reducer C2 is connected with the vertical plate C62 by screws. Through the arrangement, the whole structure is compact, the support plate C6 is used as a mounting frame of the limiting block C7, and the support plate C6 cannot interfere with the swing frame A; on the other hand, the support plate C6 is used as a reinforcing rib of the speed reducer, so that the installation firmness of the speed reducer is enhanced.
Preferably, the displacement detection device is two induction switches respectively arranged at two sides of the swing frame, wherein when the induction switch at one side senses an obstacle, the induction switch feeds back a signal to the controller, and the controller controls the motor to adjust the movement of the rack so as to enable the swing frame to correct the film winding direction; the inductive switch can be a photoelectric sensor, an obstacle sensor or a distance sensor; the sensor is adopted, so that the response speed is high, and the use is reliable.
In this embodiment, referring to fig. 7, two speed reducers C2 are provided, and the two speed reducers C2 are in transmission connection, and are worm gear speed reducers, wherein one speed reducer C2 is in transmission connection with the motor C3, and the other speed reducer is in transmission connection with the gear. The worm gear reducer has the advantages of reverse self-locking function and larger reduction ratio; through the transmission of two reducers, the speed of a transmission gear is well reduced, and the torque is increased.
Preferably, the swing frame driving device of the film winding machine further comprises a linear displacement sensor D (namely an electronic ruler), the detection end of the linear displacement sensor is connected with the swing frame A, and the fixed end of the linear displacement sensor is connected with the frame. The swing position of the swing frame can be monitored in real time by additionally arranging the linear displacement sensor, and the accurate positioning of the film unloading trolley and the winding shaft is facilitated.
It will be understood that equivalents and modifications will occur to those skilled in the art based on the present invention and its spirit, and all such modifications and substitutions are intended to be included within the scope of the present invention.
