Problems solved by technology

Due to the high temperature of the strips that have just been exported, the operator often has scalds when picking up the broken strips by hand. Sometimes the operator uses iron wire or welding rods to build the strips...

Method used

As shown in Figure 1, device is placed on water tank 3, and the roller frame on the left and right sides of strip support 5 adjusts the position on the left and right sides of water tank 3, and the push rod initial state of horizontal cylinder 1 is stretched in Outside, the scraper 6 is in a straight state, that is, at the position of 0 degrees, and the push rod of the vertical cylinder 2 is in a contracted state. When a strip breaks, you only need to press the start button, and the micro motor 7 rotates to turn the scraper 6 90 degrees to the same position. The conveying direction of the strip is parallel, the piston of the horizontal cylinder 1 shrinks rapidly, the vertical cylinder 2 extends the piston, and the scraper 6 lifts the broken material extruded from the head of the extruder, and lifts it up slightly to avoid scr...

Abstract

The invention relates to a device for overlapping when a plastic extruder has a broken strip. The device for overlapping the broken strip of the plastic extruder comprises a plastic extruder head (8) and a cooling water groove (3) positioned in the lower part of the extruder head (8); one side of a strip bracket (5) traversing two sides of the cooling water groove (3) is provided with a vertical cylinder (2); the end part of a push rod of the vertical cylinder (2) is connected with a horizontal cylinder (1); the direction of a push rod of the horizontal cylinder (1) is consistent with the length direction of the strip bracket (5); and the end tip of the push rod of the horizontal cylinder (1) is provided with a rotary baculiform scraper (6) which is driven by a minitype motor (7). The device has a simple and reliable structure, avoids the scalding accident generated by manual overlapping and overcomes the disadvantages that in the prior art, a metal strip is inadvertently dipped on a strip material during overlapping and damages subsequent machines and equipment, thereby ensuring that a plastic granular product is not intermixed with metal chipping.

Example Embodiment

[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.
