Device for overlapping broken strip of plastic extruder

[0019] The present invention will be further explained below in conjunction with the drawings.

[0020] Such as figure 1 As shown, the device is placed on the water tank 3, the roller brackets on the left and right sides of the long support 5 are adjusted in position on the left and right sides of the water tank 3. The initial state of the push rod of the horizontal cylinder 1 is extended outside, and the scraper 6 is in the extended position. Straight state, that is, at the 0 degree position, the push rod of the vertical cylinder 2 is in the contracted state. When the strip is broken, you only need to press the start button, and the micro motor 7 rotates the scraper 6 to 90 degrees to the direction of the conveying movement of the strip. Parallel, the piston of the horizontal cylinder 1 quickly retracts, and the vertical cylinder 2 stretches the piston. The scraper 6 lifts the material-breaking head extruded by the extruder head and slightly lifts it to avoid scratching other normal running strips. Glue the broken ends to the strips that move normally on the side, stick them together and drive them forward together, eliminate the faults left by the accumulation of broken strips, avoid the scalding accidents caused by manual operation of the strips, and eliminate the prior art Inadvertently dipping the metal strips on the strips damages the follow-up machinery and equipment when laying the strips, ensuring that the plastic pellet products are not mixed with metal scraps. After the scraping is finished, the horizontal cylinder 1 quickly extends the piston push rod again, and the micro-motor 7 rotates the scraper 6 by 0 degrees to return to the initial state. The above actions and cooling can be programmed and controlled by time relays and programmable controllers.
