[0027] Working principle: The semi-conductive buffer water-blocking belt on the water-blocking belt cylinder 3 is drawn out, first passes through the guide roller 7, at this time, the guide mechanism 4 starts to work, under the joint action of the springs 41 and 45, the two arc-shaped guide plates 42 are continuously pushed to the center, a slight lateral restraint force is generated on the water-blocking belt wound on the water-blocking belt cylinder 3, forcing it to travel along the central path, completing the preliminary centering and guiding; At this time, the slide columns 43 on the outer wall of the arc-shaped guide plates 42 push the surface of the water-blocking belt when it is driven, and the guide sleeves 46 further ensure that the water-blocking belt does not deviate when it is driven on the guide roller 7; The water-blocking belt that has been preliminarily guided continues to move downward, passes through the guide roller 2, and the dispersing rod on the guide roller 2 further expands the belt to prevent it from wrinkling, and then the water-blocking belt enters the fixed mechanism 5 region and is driven between the upper and lower dispersing assemblies 51 Normal flattening: under the pushing of the spring 514, the upper and lower slide sleeves 513 drive the dispersing balls 52 on their surfaces to closely adhere to the upper and lower surfaces of the water-blocking belt, and these dispersing balls 52 effectively flatten and compact the water-blocking belt and drive away the air inside, creating the best conditions for clean and smooth cutting; Dynamic shaking anti-sticking: the shaking assembly 54 works synchronously, the fixed block 541 rotates periodically with the guide roller 2 8, the rotating sleeve 542 on the fixed block 541 is rotated, the contact rod 544 of the upper sliding sleeve 513 is impacted, and when the rotating sleeve 542 contacts the contact rod 544, extrusion is generated, so that the spring 5 43 is compressed, and when the rotating sleeve 542 and the contact rod 544 are separated, the spring 5 43 resets the rotating sleeve 542 to slide outwards on the outer wall of the fixed block 541, and the whole sliding sleeve 513 and the dispersing ball 52 generate high-frequency micro-vibration, which can effectively break the adhesion between the semi-conductive layer of the water-blocking tape and the dispersing ball 52, prevent the water-blocking tape from being adhered and adhered to the ball, and ensure the continuity and stability of the flattening process. When cutting is needed, the cutting assembly 53 is started, the hydraulic push cylinder 531 pushes the lower fixed sleeve 511 to overcome the elastic force of the spring 4 32 to move upwards, the upper and lower fixed sleeves 511 are close to each other, and the dispersing balls 52 on the two sliding sleeves 513 contact each other, at this time the sliding sleeves 513 stop moving, and the fixed sleeves 511 continue to move relatively and compress the spring 3 14, and the two cutting knives 534 fixed thereon pass through the rectangular holes 535 on the sliding sleeves 513, and are accurately closed like scissors, completing the cutting of the flattened water-blocking tape. During the extension and retraction of the cutting knives 534, the cutting faces slide through the wedge-shaped cleaning rods 551 in the cleaning assembly 55, and since the inclination angle of the wedge-shaped cleaning rods 551 is the same as the opening angle of the cutting knives 534, and the wedge-shaped cleaning rods 551 are always close to the cutting faces under the action of the reset spring 553, the wedge-shaped cleaning rods 551 can completely scrape off the semi-conductive glue and SAP powder adhered to the cutting knives 534 after each cutting, which solves the problems of poor cutting, wire drawing and product contamination caused by the adhesion of the cutting knives; After cutting is completed, the hydraulic push cylinder 531 is decompressed, the lower fixed sleeve 511 is moved downwards, and the lower fixed sleeve 511 is reset under the action of the spring 4 32, the cutting knives 534 are retracted, and the upper and lower sliding sleeves 513 are recombined under the action of the spring 3 14, preparing for flattening the next water-blocking tape and starting a new working cycle.
