In addition, in the embodiment, the distance between the second front roller 52 and the second rear roller 53 is smaller than the distance between the first front roller 12 and the first rear roller 13, so that the refining effect of the second unit 5 is better than that of the first unit 1, and the product quality is effectively improved. As shown in fig. 2, 3 and 5, a displacement sensor 852 is disposed on one side of the first frame 11 and the second frame 51, where the two bearing blocks 8 sharing the same driving rod 85 are close to each other, and the displacement sensor 852 is disposed on one of the bearing blocks 8 and is in communication control connection with a corresponding servo motor 851. Thus, the servo motor 851 is controlled by the displacement sensor 852 to stop driving the driving rod 85 to rotate, so that the accuracy of the position adjustment before the first front roller 12, the first rear roller 13, the second front roller 52 and the second rear roller 53 is effectively ensured, and the distance between the second front roller 52 and the second rear roller 53 is ensured to be smaller than the distance between the first front roller 12 and the first rear roller 13.

As shown in fig. 2 and fig. 3, in the present embodiment, the tool holders 6 on the first frame 11 and the second frame 51 each include a guide rod 61 parallel to the first front roller 12, two ends of the guide rod 61 are respectively fixed on the corresponding first frame 11 and the second frame 51, two tool holders 63 are slidably mounted on the guide rod 61, the tool holders 63 are connected to a fixing member for fixing the positions thereof, and a vertically arranged cutter 64 is detachably and fixedly mounted on each tool holder 63. The fixing part comprises an adjusting rod 62 which is parallel to the corresponding guide rod 61 and is positioned and rotatably installed on the corresponding first frame 11 and the corresponding second frame 51, the adjusting rod 62 is in threaded connection with the corresponding two tool holders 63, the thread turning directions are opposite, and one end of the adjusting rod 62 is further connected with an adjusting motor 621 which drives the adjusting rod 62 to rotate.

As shown in fig. 3 or 4, the adjusting rod 62 can be driven to rotate by the adjusting motor 621, and under the limit action of the guide rod 61 and the adjusting rod 62 on the tool apron 63 and the threaded connection action of the adjusting rod 62 and the tool apron 63, the two tool aprons 63 are driven to approach or separate from each other, that is, the position of the cutter 64 is adjusted; the position of the knife holder 63, namely the position of the cutter 64, can be fixed only by stopping the adjustment motor 621 to drive the adjustment rod 62 to rotate, so that the cutting effect of the cutter 64 on impurities gathered at two ends of the film is ensured. In the present embodiment, the cutting blade 64 is detachably and fixedly mounted on the corresponding tool seat 63 by a screw (not shown), so that the cutting blade 64 can be replaced conveniently.

The working principle and the using method of the invention are as follows:

the position of the cutting knife 64 on the knife rest 6 is adjusted according to actual use requirements, and the distance between the first front roller 12 and the first rear roller 13 and the distance between the second front roller 52 and the second rear roller 53 are adjusted through the adjusting bearing seat 8. Feeding from the lower end of the climbing belt 2, the climbing belt 2 feeding the sizing particles into a hopper 22, and feeding from the hopper 22 to be refined between the first front roller 12 and the first rear roller 13; the refined film of the first unit 1 is cut off the impurities at the two ends by the cutter 64, and the cut impurities and better film products bypass the corresponding guide rollers 9 and respectively enter the corresponding waste material cavity 32 and the corresponding crushed material cavity 31 from the feed inlet 33 of the crusher 3 close to one side of the first unit 1 for crushing; the rubber particles in the crushing cavity 31 fall into the crushing hopper 35 and then fall onto the conveyer belt 41, and are conveyed to a position between the second front roller 52 and the second rear roller 53 through the conveyer belt 41 for secondary refining; the impurity that first unit 1 was not completely detached gathers in the film both sides again through the refining of second unit 5, and the cutter 64 on the second frame 51 cuts off impurity, and impurity bypasses corresponding guide roller 9 and gets into corresponding waste material chamber 32 respectively from rubbing crusher 3 near the feed inlet 33 of second unit 5 one side and smashes, and the impurity that first unit 1 and the refining of second unit 5 produced falls into from waste hopper 36 through the crushing of rubbing crusher 3 and collects in corresponding waste material basket 37, and the film product of better quality is carried forward and is collected.
