Furthermore, a locus circle formed by a point on the first gear pitch circle, which is far away from the output shaft of the first speed reducer motor, and the output shaft of the first speed reducer bypasses is tangent to the pitch circle of the second gear.

The working principle is as follows: when the rolling of the plaster on the rolling part is finished, the second speed reducing motor stops rotating, the rolling of the plaster stops, and then the plaster is cut off. Then the first reducing motor is driven, the first rotating frame and the second rotating frame synchronously rotate, the first gear is disengaged from the second gear, the rolled plaster is rotated to an unloading position along with the rolling roller, a new rolling roller is correspondingly rotated to a rolling position, then a worker sticks the end part of the plaster to the surface of a bobbin of the rolling roller row, and then the second reducing motor is started to drive the new rolling roller to rotate so as to roll the plaster again. While the plaster is being wound, the worker can synchronously unload the plaster on the winding roller and reload the bobbin on the winding roller.

Has the advantages that: compare in the tradition rolling machine of cutting, the utility model provides a winding mechanism can realize the synchronous loading to the quick uninstallation of the plaster subsides that the rolling was accomplished and the bobbin, very big promotion the production efficiency of enterprise.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

An automatic cutting and winding device for plaster patches as shown in fig. 1-3 comprises a frame 10, which is provided with a longitudinal cutting part 20, a guiding part 30, a slitter edge winding part 40, a tension control part 50 and a winding part 60. Wherein, the longitudinal cutting part is used for cutting the whole plaster into strips; the guiding part is used for guiding the advancing direction of the split plaster; the waste edge winding part is used for winding two backing cloth waste edges which are not coated with the plaster and are generated after cutting; the tension control part is used for detecting the tension of the plaster in the rolling process and adjusting the tension; the rolling part is used for rolling the cut plaster. Specifically, the winding part includes at least one winding mechanism 61, which includes an active rotating component 611 and a passive rotating component 612. The driving rotation assembly includes a first rotation frame 6111 and a first speed reduction motor 6112. The first rotating frame is provided with a rotating shaft to realize rotatable connection with the rack, the first speed reduction motor is fixedly installed on the outer side face of the rack, and an output shaft of the first speed reduction motor is coaxially and fixedly connected with the rotating shaft on the first rotating frame to drive the first rotating frame to rotate. At least two first claw discs 6113 are uniformly and centrosymmetrically distributed on the side surface of the first rotating frame facing the driven rotating assembly, and the first claw discs are rotatably connected with the first rotating frame. Meanwhile, a plurality of first gears 6114 corresponding to the first claw discs one to one are further arranged on one side of the first rotating frame, which faces away from the passive rotating assembly 612, and the first transmission teeth are in transmission connection with the first claw discs so as to realize synchronous rotation of the first and the second claw discs. Meanwhile, a second speed reduction motor 6115 is arranged on the outer side surface of the rack, an output shaft of the second speed reduction motor extends into the inner side of the rack, and a second gear 6116 is fixedly arranged on the output shaft coaxially with the output shaft. The first gear is meshed with the second gear through the driving of the first speed reducing motor, and the first claw disk is driven to rotate through the driving of the second speed reducing motor. In addition, as shown in fig. 1, the passive rotating assembly 612 includes a second rotating frame 6121 rotatably connected to the frame 10, second claw discs 6122 corresponding to the first claw discs 6113 are distributed on one side of the second rotating frame facing the active rotating assembly 611, and the second claw discs are rotatably connected to the second rotating frame.
