In order to ensure that the positioning block 9 can slide stably, the movable block 11 is limited by the limited groove 10, thereby effectively improving the stability of the movable block 11. The movable block 11 is fixedly connected to one end of the third spring 12, the inner surface of the limiting groove 10 is fixedly connected to one end of the third spring 12, the lower surface of the limiting groove 10 is fixedly connected to the insertion rod 15, the front surface of the collecting box 1 is fixedly connected to the cross bar 13, the upper surface of the cross bar 13 is provided with circular holes 14 in a linear array, the inner surface of the circular hole 14 is slidably connected to the insertion rod 15, in order to be able to limit the sliding rod 41, the sliding rod 41 is limited by the set circular hole 14 and the insertion rod 15, thereby effectively ensuring that the scraper 43 will not move during use.
[0030] In this embodiment, by providing a sliding rod 41, a fixed plate 42 and a scraper 43, part of the glue material on the surface of the brush roller 32 can be scraped off to prevent the brush roller 32 from applying too much glue material to the surface of the printed film. At the same time, the scraper 43 can be folded and adjusted to adapt to brush rollers 32 of different specifications and facilitate cleaning of the inside of the collection box.
[0031] Working principle: when the inside of the collecting box 1 needs to be loaded, the water pump 34 is started. After the rubber material in the storage box 33 is pumped into the collecting box 1, the output shaft of the motor 31 drives the brush roller 32 to rotate to brush the surface of the printed film. During the brushing process of the brush roller 32, the excess rubber material is scraped off by the scraper 43 and falls into the collecting box 1. At the same time, according to the size of the brush roller 32, the distance between the insertion rod 15 and the brush roller 32 can be adjusted by pulling out the insertion rod 15 from the circular hole 14. When the inside of the collecting box 1 needs to be cleaned, the scraper 43 can be pulled. At this time, the positioning block 9 drives the slider 6 to move toward the front end of the slide groove 5 through the bracket 16, and drives the slider 6 to move forward. When the slider 6 drives the conical rod to move to the slot position, the conical rod is inserted into the slot through the elastic member to limit the folded scraper 43.
