Abstract
Description
Technical Field
[0001] This utility model relates to the field of rewinding machine technology, and in particular to a splicing rewinding machine. Background Technology
[0002] Rewinding machines are generally used for rewinding and slitting mica tape, paper, and film, effectively splitting them in two. They are commonly used to slit wide rolls and play an important role in subsequent re-slitting. When the rewinding machine produces defective rolls or rolls with too small a diameter, manual operation is required to cut off the defective parts or to cut the ends of the two rolls with the smaller diameters flat before bonding them together with tape. However, because the rolls are lightweight and prone to shifting, alignment is difficult to perform and the alignment accuracy is hard to guarantee. Therefore, manual splicing methods cannot meet the requirements. Summary of the Invention
[0003] The purpose of this utility model is to overcome the shortcomings of the existing technology and provide a splicing and rewinding machine with simple structure, reasonable design, convenient splicing, and improved rewinding efficiency and rewinding effect.

[0021] Example:
[0022] like Figures 1 to 5 The splicing and rewinding machine shown includes a frame 1, with an unwinding roller 2 and a take-up roller 3 respectively at the front and rear ends of the frame 1; the frame 1 is equipped with multiple sets of drive motors 11 for driving the unwinding roller 2 and the take-up roller 3 to rotate; the frame 1 is also equipped with several intermediate guide rollers 12 between the unwinding roller 2 and the take-up roller 3; the frame 1 is rotatably equipped with a tension arm 13 between the slitting roller 6 and the take-up roller 3, and the tension arm 13 is equipped with a tension adjusting roller 14.
[0023] One end of the unwinding roller 2 is rotatably mounted on the frame 1 and rotatably connected to the drive motor 11, while the other end of the unwinding roller 2 is suspended in the air to facilitate the placement of the roll material onto the unwinding roller 2.
[0024] One end of the take-up roller 3 is inserted into the frame 1 and rotatably connected to the drive motor 11. The other end of the take-up roller 3 is provided with a fixing device 31 between it and the frame 1. The frame 1 is provided with unloading guide arms 32 at both ends of the lower side of the take-up roller 3. The frame 1 is provided with an unloading motor 33. The unloading motor 33 is connected to the unloading guide arm 32 through the unloading chain 34 to facilitate unloading of the take-up roller 3. The fixing device 31 includes a fixing seat 311 and a fixing cylinder 312. The fixing seat 311 is provided with a placement groove 313. The fixing cylinder 312 is located at the opening of the placement groove 313 and can close the opening of the placement groove 313.
