Detailed ways

The present invention will be further described below with reference to the accompanying drawings and specific embodiments. Those of ordinary skill in the art will be able to implement the present invention based on these descriptions. In addition, the embodiments of the present invention referred to in the following description are generally only some embodiments of the present invention, not all of the embodiments. Therefore, based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.

Example: As shown in Figures 1 to 2, a storage box can be arranged between the printing process section 13 and the oven curing section 14, mainly to ensure the printing process section during screen printing of the sheet material. The substrate 1 at 13 is in a "static" state, and at the same time, the substrate 1 at the curing section 14 of the oven is in a moving state, so as to prevent the sheet from causing adverse effects under the high temperature of the oven, that is, in the storage box 15. The substrate 1 that has been printed in the printing process section 13 and is to be entered into the oven curing section 14 is left to prevent the substrate 1 at the oven curing section 14 from pulling the substrate 1 in the printing process section 13, so as to ensure that the film is material quality.

In order to facilitate the entry of the substrate 1, the storage box 15 is provided with an opening. In order to prevent the position of the substrate 1 from deviating during the movement process, an adsorption guide roller 9 is installed in the storage box 15. The adsorption guide roller 9 includes a roller body 6 on the inner ring and a protective layer 2 on the outer ring. The roller body 6 is made of metal material, which can effectively ensure the service life of the adsorption guide roller 9 and reduce the cost of use. In order to avoid causing damage to the surface of the substrate 1. Wear, so as to ensure the quality of the base material 1, the protective layer 2 is made of rubber material. The above-mentioned protective layer 2 covers the above-mentioned roller body 6 and constitutes an integrated suction guide roller 9 .

In order to realize the adsorption function of the adsorption guide roller 9, the protective layer 2 is provided with a number of holes 10. The diameter of the holes 10 is about 1-2 mm. If the diameter of the holes 10 is less than 1 mm, the suction force is not enough, and it is difficult to adsorb the substrate 1. , it is easy to cause the displacement of the substrate 1; if the diameter of the hole 10 is greater than 2mm, when the substrate 1 is too thin, the substrate 1 will easily enter the hole 10, and the trace of the hole will be formed on the surface of the substrate 1. , affecting the quality of the substrate.

In order to ensure the adsorption effect, the above-mentioned roller body 6 is provided with air extraction holes 3, and the above-mentioned air extraction holes 3 are arranged in a one-to-one correspondence with the above-mentioned holes 10, and then the air is drawn by the air extraction device 4 arranged on the side of the above-mentioned adsorption guide roller 9, so that the substrate can be drawn. 1 is adsorbed on the adsorption guide roller 9. In order to reduce the use cost, the size of the above-mentioned air extraction device 4 can be adapted to the size of the wrapping angle of the base material 1 in contact with the above-mentioned protective layer 2 , as long as the requirements for adsorbing the base material 1 on the suction guide roller 9 are met. The air extraction device 4 has an air extraction pipeline 5, through which air is drawn out to form a negative pressure. In order to ensure the stability of the ventilation device 4, the ventilation device 4 is fixed at the position of the ventilation hole 3 of the roller body 6 by the fixing rod 12. The central axis of the set is symmetrical.

In order to ensure the operation of the substrate 1 in the storage box 15, there are multiple suction guide rollers 9 in the storage box 15, and the plurality of suction guide rollers 9 are arranged at equal distances, which can effectively reduce the running time of the substrate 1. The probability of positional deviation occurs in the process, so as to ensure the printing effect of the substrate 1 at the printing process section 13 and ensure the printing quality.

Further, in order to ensure the use effect, the above-mentioned storage box 15 is a sandwich design, the inner surface is provided with a plurality of through holes 7, the outer layer is a sealed structure, and an air extraction device 8 is installed on the outer layer. The wind head extends into the interlayer, so that the pressure in the storage box 15 is within a certain range, and the influence on the substrate 1 is reduced.

The storage box 15 is also provided with a fixing frame 11 . The fixing frame 11 is fixedly connected with the fixing rod 12 and the two are arranged perpendicular to each other. The outer surface of the fixing frame 11 and the inner surface of the storage box 15 When installing the suction guide roller 9, the levelness and parallelism between the suction guide roller 9 and the front and rear guide rollers need to be consistent.

A gap is set between the air extraction device 4 and the above-mentioned roller body 6 to ensure that the substrate 1 can be adsorbed on the adsorption guide roller 9 and at the same time to ensure that the adsorption guide roller 9 will not be caused by friction with the air extraction device 4 when it rotates. damage.

The function of the storage box 15 in this embodiment is to ensure that the substrate 1 in the printing process section 13 is in a "static" state during normal printing, and at the same time to ensure that the substrate 1 of the oven curing section 14 is "moving" . The working principle is as follows: 1) The guide roller on the storage box 15 and a vertical row of guide rollers on the left inside the storage box 15 are active rollers, which are connected with the motor of the printing section. When printing starts , at this time, the guide roller and a vertical row of guide rollers on the left inside the storage box 15 do not rotate to ensure that the substrate 1 is in a "static" state during the printing process. When the printing is completed once, the guide roller and the storage box A vertical row of guide rollers on the left inside the body 15 starts to rotate, and at the same time the unprinted substrate is transferred to the printing process, the printed substrate is transferred out of the printing process, and then the next printing is performed. The vertical row of guide rollers on the left side of the storage box 15 is also the adsorption guide roller 9. The function of the adsorption guide roller 9 is to ensure that when the guide roller above the storage box 15 passes through the joint for connecting and changing rolls, because the joint is not If it is flat, the base material 1 cannot be completely attached to the guide roller. At this time, the suction force of the guide roller cannot drive the base material 1. Therefore, it needs to rely on the guide roller on the left side of the storage box 15. 2) A vertical row of guide rollers on the right side of the storage box 15 is also a driving roller, which is connected with the motor in the curing section of the oven and the winding part, and a vertical row of guide rollers on the right It is always rotating to ensure that the printed substrate is always moving in the oven, so as to prevent the substrate from staying in the oven and causing damage. In addition, the substrate in the printing process is in a state of “moving” and “static” switching back and forth, so the speed of the vertical guide roller on the right to rotate and transport the substrate is lower than the speed of the printing process, that is, to ensure that the substrate in the curing section of the oven is always In operation, it also ensures the normal progress of the printing process. 3) The hole design on the inner surface of the storage box 15 is, on the one hand, to further adsorb the substrate 1 on the guide roller, so that the movement track of the substrate 1 is guaranteed to be a straight line, so as to prevent the substrate 1 from not being Gravity, when the reel goes over the joint, the grid pattern is printed crooked in the printing process and the winding end face of the winding part is uneven, resulting in bad losses; on the other hand, the ventilation of these small holes forms a negative pressure, which will print Part of the harmful gases in coatings and inks are absorbed to reduce environmental pollution.
