In order to limit the length of the adhesive tape 1 loosened each time, a worker selects to adjust the rotation resistance between the driving roller 25 and the roller 26 through an adjusting piece according to the actual conveying condition of the adhesive tape 1, specifically, on the premise of keeping the current of the power supply unchanged, the position of a poking block on the slide rheostat is adjusted, the current of the power supply introduced into the electromagnet is adjusted by adjusting the resistance of the slide rheostat, the magnetic strength of the electromagnet is changed, and when the magnetic strength of the electromagnet is gradually increased, the adsorption force of the electromagnet on the driving roller 25 is also gradually increased, so that the rotation resistance of the driving roller 25 is increased. When the pulling force of the adhesive tape 1 on the roller 23 is maintained within a certain range, that is, when the pulling assembly pulls the adhesive tape 1 at a pulling speed within a certain range, the larger the rotation resistance of the driving roller 25 is, the smaller the range in which the roller 23 can drive the driving roller 25 to rotate is, the smaller the range in which the driving roller 25 can drive the placing roller 21 to rotate is, and further, the shorter the length of the adhesive tape 1 loosened at a time is. Accordingly, the resistance between the drive roller 25 and the roller 26 becomes gradually smaller, and the length of the adhesive tape 1 increases in a single unwinding.

One roll of sticky tape 1 is carrying the use in-process, and the staff can be ready to supply reserve sticky tape 1, unreels the subassembly and is equipped with two sets ofly, will supply reserve sticky tape section of thick bamboo 22 to install on the second group unreels the subassembly after, will supply reserve sticky tape 1's tip to place briquetting 47 on second brace table 41 under to make sticky tape 1's tip and second brace table 41 set up the one end tip parallel and level of first cutter 42, the process of placing supply reserve sticky tape 1 does not influence the transport of original sticky tape 1.

When the original adhesive tape 1 is about to be used up, the tail end of the adhesive tape 1 is separated from the unreeling assembly, after the tail end of the adhesive tape 1 moves through the infrared sensor 31, the infrared sensor 31 can not sense the adhesive tape 1 any more, the original adhesive tape 1 is judged to be about to be used up, the second supporting table 41 is driven to slide down manually or through program control at the moment, the pressing block 47 on the first supporting table 43 is driven to slide down, the pressing block 47 on the first supporting table 43 presses the original adhesive tape 1, the limiting block 45 is driven to slide simultaneously, the limiting block 45 limits the tail end of the adhesive tape 1, the first cutter 42 cuts off the tail end of the adhesive tape 1 which is still positioned on the first supporting table 43, and the end of the supplementary standby adhesive tape 1 positioned on the second supporting table 41 is connected with the tail end of the original adhesive tape 1. The distance sensor 33 senses the distance that the second supporting platform 41 slides down, and when the upper surface of the second supporting platform 41 is flush with the upper surface of the first supporting platform 43, the second supporting platform 41 stops sliding down. At this time, the stopper 45 is slid to be reset, the end of the cut adhesive tape 1 is released, and the end of the adhesive tape 1 is collected for subsequent processing.

The staff inserts the tip of adhesive tape 66 in the guide way in advance, after the tip of two sets of sticky tapes 1 joints, drive slide 62 slides downwards, when hot pressing piece 61 is about to be close to sticky tape 1, drive spool 64 rotates, adhesive tape 66 on spool 64 loosens, adhesive tape 66 is guided hot pressing piece 61 below, in order to avoid hot pressing piece 61 still far away from sticky tape 1, take place certain flagging problem behind adhesive tape 66 loosening, and aluminium foil paper has certain hardness as adhesive tape 66, when being close to sticky tape 1, can be better with leading-in adhesive tape 66 between sticky tape 1 and hot pressing piece 61, even there is certain flagging in the end of adhesive tape 66 this moment, also can hang down on sticky tape 1, can not influence the bonding.

Along with the gliding of hot pressing block 61, hot pressing block 61 with bonding tape 66 pressfitting on sticky tape 1, heat hot pressing block 61 through the electrical heating stick, accomplish the hot pressing for the pressfitting effect is better. After the pressing is finished, the second cutter 65 slides downwards to cut off the adhesive tape 66, the second cutter 65 is positioned between the guide block 63 and the hot pressing block 61, and after the cutting, the end part of the adhesive tape 66 is positioned in the guide groove, so that the adjustment by a worker is not needed. After the pressing, the second cutter 65 and the sliding plate 62 are both slid upwards to reset. The pressing block 47 on the first supporting table 43 slides upwards to be reset, and the adhesive tape 1 continues to be dragged and conveyed.

In the switching and butting process of the adhesive tape 1, the pressing block 47 on the first supporting table 43 presses the rear end of the original adhesive tape 1 to limit and fix the rear end of the adhesive tape 1, the traction assembly continues to pull the adhesive tape 1, the adhesive tape 1 pulls the buffer wheel 13 to move upwards, and the part of the adhesive tape 1 stored between the buffer wheel 13 and the guide wheel 11 continues to be conveyed to finish the subsequent adhesive tape pasting work of the adhesive tape 1 without affecting the switching and butting process of the adhesive tape 1. When the slide block 14 is located at the lowest end of the slide rail 12, the larger the vertical distance between the slide block 14 and the mounting block 15 is, the longer the adhesive tape 1 can be stored, or the more the mounting blocks 15 and the slide blocks 14 are provided, the longer the adhesive tape 1 is wound in a turning way when passing through the guide wheel 11 and the buffer wheel 13, and the number or the positions of the mounting blocks 15 and the slide blocks 14 are set according to the time required by actual butting.

And after the adhesive tape 1 is switched and butted once, continuously preparing the next adhesive tape 1 to be replaced. In the in-service use process, the level of detecting component can set up the level that is higher than the switching module (can set up the guiding axle that is used for 1 direction to sticky tape between detecting component and the switching module according to actual processing condition), and when the staff was placing supplementary reserve sticky tape 1, supplementary reserve sticky tape 1 can not pass through detecting component earlier to avoid influencing the detection of detecting component to original sticky tape 1.
