The embodiment provides a silk screen printing machine roll paper structure for make the paper tape realize forward and reverse motion fast, realize the quick material loading, silk screen printing and unloading process to photovoltaic products such as solar cell panel.
As shown in fig. 2 and 3, the reel structure 100 of the silk-screen printing machine mainly comprises a motor 10, a transmission mechanism 20 and a rotating disc 30, wherein the transmission mechanism 20 is connected with the motor 10 for driving the paper tape 40 to move forward or backward.
Specifically, the above-mentioned transmission mechanism 20 includes a paper roll synchronizing wheel 21, an inner paper roll synchronizing wheel 22 and a motor synchronizing wheel 23, the paper roll synchronizing wheel 21 is connected to the motor 10 through a paper roll electromagnetic clutch 211, the inner paper roll synchronizing wheel 22 is connected to the motor 10 through an inner paper roll electromagnetic clutch 221, and the motor synchronizing wheel 23 is connected to the motor 10 through a timing belt 231.
The paper tape 40 is wound on the turntable 30, and one end of the paper tape 40 is wound on the rotating shaft where the inner roll paper synchronizing wheel 22 is located, and the other end is wound on the rotating shaft where the outer roll paper synchronizing wheel 21 is located.
When the motor 10 rotates positively, the paper winding electromagnetic clutch 211 is energized to connect the paper winding synchronizing wheel 21 with the rotating shaft of the motor 10, and the motor 10 drives the paper winding synchronizing wheel 21 to rotate and the paper tape 40 to move positively. When the motor 10 is reversed, the inner paper winding electromagnetic clutch 221 is electrified to connect the inner paper winding synchronous wheel 22 with the rotating shaft of the motor 10, and the motor 10 drives the inner paper winding synchronous wheel 22 to rotate and drives the paper tape 40 to move reversely. The motor synchronizing wheel 23 is used to provide tension and auxiliary power to the movement of the paper web 40.
Since the movement and stop of the paper tape 40 are instantaneously completed in a short time and each of the rotating members itself has moment of inertia, the paper tape 40 is liable to be arched at the moment of stop, and therefore, the present embodiment is further provided with a damper mechanism 50, the damper mechanism 50 including a damper 51 and a damper gear 52 provided on the rotation shaft of the motor synchronizing wheel 23. The above-mentioned paper-wrapping synchronizing wheel 21, paper-inner synchronizing wheel 22 and motor synchronizing wheel 23 are located on one side of the turntable 30, and the gear transmission pair associated with the damping mechanism 50 is provided on the other side of the turntable 30 in this embodiment, specifically:
as shown in fig. 4, a reel gear 212 is further disposed on the rotating shaft where the reel synchronizing wheel 21 is located, and the reel gear 212 is connected to the rotating shaft thereof through an outer unidirectional bearing 213. The rotating shaft of the inner paper roll synchronizing wheel 22 is also provided with an inner paper roll gear 222, and the inner paper roll gear 222 is connected with the rotating shaft thereof through an inner one-way bearing 223. The paper roll gear 212 is engaged with the paper roll gear 222, and the paper roll gear 222 is engaged with the damper gear 52. When the paper roll gear 212 is a drive wheel, the inner one-way bearing 223 provides torque to the inner paper roll gear 222 to couple the damping mechanism 50; when the inner wrap gear 222 is a drive wheel, the outer one-way bearing 213 provides torque to the outer wrap gear 212 and couples the damping mechanism 50. In this way, no matter which roll paper synchronizing wheel is driven by the motor 10 to rotate, the inner roll paper gear 222 or the outer roll paper gear 212 can be meshed with the damping gear 52 and further coupled to the damper 51, so that the paper tape 40 is always kept in a tensioned state, and no doming phenomenon occurs.
By the above structure, it can be found that the motor 10 shares a set of damping mechanisms 50 when the paper tape 40 is driven to move forward and backward by the forward and backward rotation, so that it is not necessary to provide a set of damping mechanisms respectively, thereby simplifying the structure of the product and directly reducing the moment of inertia of the whole paper roll structure 100.
To further reduce the moment of inertia of the roll paper structure 100, the inner roll paper synchronizing wheel 22, the inner roll paper gear 222, the outer roll paper synchronizing wheel 21, the outer roll paper gear 212, the motor synchronizing wheel 23, and the damper gear 52 of the present embodiment are all made of nylon. Compared with metal materials, the material has lighter weight and smaller moment of inertia.

The function of the rotating roller 32 is to reduce friction with the turntable 30, on the one hand to reduce the power loss of the motor 10 and on the other hand to reduce wear and increase the service life of the paper strap.
The rotating roller 32 of the present embodiment is provided in a hollow structure, so that the moment of inertia of the rotating roller 32 can be reduced, and the moment of inertia of the entire roll paper structure 100 can be reduced.
The present embodiment also provides that the paper-wrapping synchronizing wheel 21 is provided coaxially with the paper-wrapping electromagnetic clutch 212, and that the inner paper-wrapping synchronizing wheel 22 is provided coaxially with the inner paper-wrapping electromagnetic clutch 222. In this way, the compactness of the paper winding structure 100 can be improved, the whole volume of the product can be reduced, the rotational inertia of the transmission mechanism 20 can be reduced, and the processing efficiency of the silk-screen printing machine can be further improved.
