Embodiment
It is right below in conjunction with the accompanying drawings in order to make those skilled in the art be better understood when technical scheme
Its embodiment is described in detail：
Please refer to Fig.1 and Fig. 2, highly preferred embodiment of the present invention, a kind of coil tightly around device, including base 1, transmission shaft 5,
Swing arm 6, transition axis 7, support shaft 8,9, two compression cylinders 2 of pinch roller and two joining beams 4.
Two compression cylinders 2 are separately mounted on base 1, and two compression cylinders 2 are arranged in parallel；Transmission shaft 5 is installed on
On base 1, transmission shaft 5 is located at the front of compression cylinder 2, and the central axes of transmission shaft 5 are perpendicular to the piston rod of compression cylinder 2
Central axes；The piston rod of two compression cylinders 2 is connected by two joining beams 4 with transmission shaft 5 correspondingly, compression cylinder 2
Piston rod is connected with joining beam 4 by axis pin；Joining beam 4 is connected with transmission shaft 5 by square key；The rear end of swing arm 6 is installed on transmission shaft 5
On, swing arm 6 is connected with transmission shaft 5 by square key；Transition axis 7 is retractably installed in swing arm 6, and transition axis 7 passes through with swing arm 6
Pressing plate is connected, and guiding axis is provided with swing arm 6, and transition axis 7 stretches along the guiding axis；Support shaft 8 is fixed on by lock-screw
