[0003] The current reel mechanism has a series of problems. Most reels adopt single-sided driving mode, which causes uneven force on the reel during operation. After long-term use, the installation position of the reel is prone to deviation, and position deviation, reel tilting and other conditions may occur during the winding process, which may even cause out-of-disk swelling deformation, which not only affects the normal use of the reel, but also greatly shortens its service life. In addition, when the reel bears a large torsion, all torsion is concentrated on the reduction box, which may damage the reduction box, increase the maintenance cost and downtime of the equipment. Moreover, after the reel chain is used for a period of time, loosening and tooth skipping phenomena are inevitable, at which time the reel is prone to displacement change, cannot guarantee the fixation of the installation position, and seriously affects the stability and reliability of the whole system. In addition, the existing sprocket tooth shape and chain material may cause unstable transmission, poor chain durability, and large vibration during equipment operation, and other problems are also more prominent, therefore a double-sided driving reel mechanism is proposed.

[0020] The use state of the utility model is: the utility model has the advantages of reasonable and simple structure, low production cost, convenient installation, complete function, when in use, the motor 1 starts, the power of the motor 1 is transmitted to the reducer 2 through the output shaft, the power is decelerated and torque amplified after the reducer 2, and then the power is transmitted to the driving chain 4 through the sprocket one 6. The driving chain 4 drives the sprocket two 7 to rotate, so that the secondary shaft 3 rotates, and the reel 5 installed on the secondary shaft 3 rotates, realizing the winding and unwinding operation of the reel.

[0021] The tensioning wheel 14 is used for adjusting the tensioning degree of the driving chain 4, ensuring the stability of chain transmission. The protection sheet metal 13 can protect the motor 1, the reducer 2 and the secondary shaft 3, preventing them from being collided by external objects and invaded by dust. The connection block 9 and the limiting block 11 can prevent the secondary shaft 3 from axial displacement during rotation, and the strengthening rod 12 can enhance the stability of the fixed seat 8. When the reel 5 bears a large torsion, the torsion is transmitted through the secondary shaft 3, avoiding the direct impact on the reducer 2.
