In the figure, the guide roller body 11, the swing roller body 12, the swing arm 13, the end plate 14, the side plate 15, the arc slotted hole 151, the induction switch 16, the bearing A17, the bearing B18, the bearing B19, the printing platform 20, the bottom film 21 and the film.

Detailed Description

Referring to fig. 1-4 of the specification, a crystal mark printing medium swing rod feeding device comprises a guide roller body 11 and a swing roller body 12, wherein the guide roller body 11 is transversely connected between two end plates 14 of a printing platform 19 in a rotating mode, the guide roller body 11 is located at an inlet of the printing platform 19, two swing arms 13 are symmetrically and fixedly connected to two end portions of the guide roller body 11, the two swing arms 13 can swing by taking the guide roller body 11 as a rotating shaft, the swing roller body 12 is transversely connected between lower end portions of the two swing arms 13 in a rotating mode, and the swing arms 13 drive the swing roller body 12 to swing up and down.

The lower end of the swing arm 13 is provided with a through hole, a bearing B18 is sleeved in the through hole, two ends of the swing roller body 12 are inserted into the two bearings B18 to form a rotary connection structure, and a fixed rod can be arranged to be connected between the two swing arms 13, so that the swing roller body 12 is rotationally connected to the fixed rod; the end plates 14 are provided with through holes, bearing nails 17 are sleeved in the through holes, two ends of the guide roller body 11 are inserted into the two bearing nails 17 to form a rotary connecting structure, and a fixed rod can be arranged to be connected between the two end plates 14, so that the guide roller body 11 is rotationally connected to the fixed rod.

The working procedure of this embodiment is: after the base film 20 enters the printing platform 19 from the inlet of the printing platform 19, the film 21 on the base film 20 is torn off, upwards bypasses the guide roller body 11, then downwards winds out from the lower part of the swinging roller body 12 and enters the winding device, the winding device and the printer synchronously run, when the tension of the film 21 changes, the two swinging arms 13 can swing by taking the guide roller body 11 as a rotating shaft, the swinging roller body 12 synchronously swings between the two swinging arms 13, the gravity of the swinging roller body 12 applies tension to the film 21, and swings up and down along with the change of the tension of the film 21, so that the film 21 is kept in a tension state at any moment.

The upper end of the swing arm 13 is fixedly connected with the guide roller body 11, so that a proper interval is reserved between the guide roller body 11 and the swing roller body 12, the film 21 enters below the guide roller body 11 from the interval, and the gravity of the guide roller applies tension to the film 21. The guide roller 11 has a size larger than that of the swing roller 12.

Referring to fig. 1-3 of the description, in the second embodiment, on the basis of the first embodiment, a side plate 15 of a case outside a swing arm 13 is provided with an inductive switch 16, the inductive switch 16 can correspond to the lower part of the swing arm 13, the side plate 15 is provided with an arc-shaped slotted hole 151, the inductive switch 16 is installed in the arc-shaped slotted hole 151, the strength of different types of films 21 is different, so that the inductive switch 16 corresponds to the corresponding adjustment position in the arc-shaped slotted hole 151, and a winding device stops winding when the films 21 are selected to have different tensional degrees, thereby preventing the phenomenon that the tensional degrees of the films 21 of different types are too large and are broken. The side plates 15 are vertically arranged, the circle center of the arc-shaped oblong hole 151 is positioned on the axis of the guide roller body 11, and the inductive switch 16 can be always positioned on the swing curve of the swing arm 13 when the position of the inductive switch 16 is adjusted in the arc-shaped oblong hole 151, so that the position signal of the swing arm 13 can not be captured.

When the tension is too high in the film 21 rolling process, the upward swing amplitude of the swing arm 13 and the swing rod is increased, at this time, the inductive switch 16 on one side is used for capturing the position signal of the swing arm 13, and transmitting the signal to the motor of the rolling device, stopping rolling, avoiding that the film 21 is broken, after the tension is recovered, the inductive switch 16 is used for capturing the position signal of the swing arm 13, and the rolling device is started to continue rolling.
