Because the pulling rollers are paired rollers, the two roller spacing is required to be accurately adjusted in the pulling process and cannot be easily changed; for the convenience of material replacement, the FPC board is usually designed into three parts, namely a jet printing part, a guiding part (about 8 m) and a connecting part (about 20 mm) (see the attached figure 1 of the specification); when the unreeling roll is replaced, the connecting part of the new coiled material and the guiding part of the previous coiled material are required to be bonded by using the transparent adhesive tape, and then the continuous transmission is driven by the pulling roll, so that the material replacement is convenient.
However, because the pulling roller is driven by the stepping motor, the motion characteristic of the pulling roller is continuous intermittent motion, and the pulling roller is often manually adhered in the process of connecting new coiled materials and old coiled materials, and has certain requirements on the adhering uniformity. In order to ensure the connection accuracy, the jet printing equipment has to be closed for waiting; on the one hand, the production efficiency can be reduced, on the other hand, the frequent start-stop of the spray printing equipment can reduce the matching degree of the spray printing equipment and the pull roll, repeated debugging is needed, and the process is tedious, time-consuming and easy to cause the waste of part of coiled materials.

Detailed Description
Referring to fig. 1 to 10, the present invention provides a technical solution: a winding structure for high-speed spray printing of a roll-to-roll FPC board comprises an unreeling roller, a winding roller, pull rollers, a spray printing part and a plurality of groups of guide rollers 3-1, wherein the pull rollers, the spray printing part and the guide rollers are distributed among the unreeling roller and the winding roller; a winding structure is arranged between the jet printing part and the unreeling roller; the winding structure comprises:
a frame 1;
a movable roller 5 and a fixed roller 4, wherein the movable roller 5 and the fixed roller 4 are respectively distributed on the lower side and the upper side of the coiled material 2; the movable roller 5 can move up and down, and the length of the coiled material 2 passing through the winding structure can be increased by being matched with the fixed roller 4 when the movable roller 5 moves upwards;
a front pair of rollers 8 and a rear pair of rollers 7; the roller bodies of the rear pair of rollers 7 are elastically and slidably arranged on the frame 1, the roller bodies of the front pair of rollers 8 are slidably arranged on the frame 1, the roller bodies of the front pair of rollers 8 and the rear pair of rollers 7 are connected through synchronous components, and the front pair of rollers 8 and the rear pair of rollers 7 respectively wind the front end and the rear end of the structure; when the movable roller 5 is driven by the linear driving piece 1-2 fixedly arranged on the frame 1 and moves upwards, the rear pair of rollers 7 are close to each other and keep a clamping state (excessive traction is prevented from being caused on the coiled material 2 of the jet printing part in the process of lifting the movable roller 5, so that the elastic deformation generated in the printing process of the coiled material 2 exceeds the allowable offset), and the increment of the coiled material 2 passing through the rolling structure is all from the unreeling roller;
the mounting shaft 6 is rotatably arranged on the frame 1 above the front pair of rollers 8, a connecting frame 6-1 is fixedly arranged on the mounting shaft 6, and a probe roller 6-3 is rotatably arranged at the lower end of the connecting frame 6-1; the two ends of the connecting frame 6-1 are provided with top blocks 6-2; connecting rods 8-1 are arranged on two sides of the roller bodies on the upper side of the front pair of rollers 8, and the connecting rods 8-1 can be clamped by the jacking blocks 6-2 so as to fix the relative positions between the two roller bodies of the front pair of rollers 8; the probe roller 6-3 can be supported and held by the web 2 in a tensioned state; after the unreeling of the unreeling roller is finished, the coiled material 2 below the detecting roller 6-3 cannot support the detecting roller 6-3, so that the mounting shaft 6 and the connecting frame 6-1 rotate, the jacking block 6-2 rotates to release the clamping state, the two roller bodies of the front pair of rollers 8 are mutually close to each other and clamp the coiled material 2, the tail end of the coiled material 2 is relatively static and kept, and the new coiled material 2 is convenient to replace; meanwhile, the roller bodies of the back pair rollers 7 are far away from each other and are separated from clamping (the clamping states of the front pair roller 7 and the back pair roller 7 are switched, so that the spray printing is ensured not to be influenced, and simultaneously, the surplus materials of the unreeling roller to be replaced are ensured to be transferred into a reeling structure in advance, so that a new coiled material 2 is convenient to replace), the linear driving part 1-2 slowly descends (the part is mainly matched with the feeding amount of the pull roller), and the spray printing unit continuously sprays the coiled material 2.
See fig. 2, 3 and 8; when the coiled material 2 in the unreeling roller in fig. 2 is about to run out, the linear driving piece 1-2 is started to move upwards, and meanwhile, the two roller bodies of the rear pair of rollers 7 are mutually close to each other, so that the coiled material 2 is clamped; at this time, all the increment generated during the ascending of the linear driving member 1-2 is supplied by the unreeling roller through the front pair of rollers 8; so that the allowance of the coiled material 2 on the unreeling roller can be rapidly and prematurely consumed; when the surplus on the unreeling roller is consumed, the coiled material 2 below the detecting roller 6-3 is out of support, the detecting roller 6-3 is also out of support and rotates along the mounting shaft 6, so that the front pair of rollers 8 is released, the two roller bodies of the front pair of rollers 8 are close to each other and clamp the coiled material 2, meanwhile, the linear driving piece 1-2 stops ascending, so that the coiled material 2 on the right side (figure 8) of the front pair of rollers 8 is in a static state for a period of time (the number or the travel of the movable roller 5 can be increased or decreased according to the requirement; the static time can be increased or decreased); when the front pair of rollers 8 is clamped, the rear pair of rollers 7 is controlled (a control source can be externally connected), and the coiled material 2 in the rolling structure is released towards the rear pair of rollers 7 under the descending cooperation of the pull roller and the linear driving piece 1-2.
The rolling structure takes the linear driving piece 1-2 as an initiating point, and the back and front pair of rollers 8 sequentially clamp the coiled material 2, so that the coiled material 2 of the unreeling roller to be replaced is rapidly rolled up, the tail end of the coiled material 2 is in a static state for a period of time, and on one hand, the adhesive material changing work is conveniently carried out by matching with manual or automatic equipment; on the other hand, the jet printing efficiency of the equipment is not affected.
