Description

Technical Field

[0001] The utility model relates to the technical field of material removal structures, in particular to a material removal structure for an open mixing mill. Background Art

[0002] The open mill is the abbreviation of the open plastic refining machine. In plastic product factories, people are used to calling it a two-roller machine. The open mill is a kind of plastic mixing equipment that was used earlier in plastic product manufacturers. On the calender production line, the open mill is before the calender and after the mixer. Its function is to mix and plasticize the uniformly mixed raw materials, and provide a relatively uniformly mixed and plasticized molten material for the calender to calender and mold plastic products. When producing cable materials, the open mill can directly refine and plasticize the powdered materials mixed according to the formula into molten materials, and then press them into sheet strips, so that the pelletizer can cut them into granules. On the floor leather production line, it can directly provide a uniformly mixed and plasticized base coating for cloth leather. The recycled waste plastic film (sheet) can also be re-refined and plasticized on the open mill.

[0003] In the process of producing adhesives, adhesive manufacturers use open mixing mills for some processes. The method for cleaning the rubber adhered to the roller is to simply fix a scraper with a scraper on the frame at an angle. When cleaning the rubber adhered to rollers of different lengths, it is usually necessary to remove the scraper as a whole. The disassembly and replacement are troublesome, resulting in the inability to quickly and conveniently apply the scraping operation of the rubber adhered to rollers of various specifications and lengths. In addition, the scraped rubber will spill everywhere, and manual centralized and regular cleaning is required later, which is troublesome, time-consuming and labor-intensive. Utility Model Content

[0006] The scraper sleeve is arranged on the blade plate, and the scraper is provided with a hand-tightening bolt for locking the scraper. The utility model can replace a new scraper of the same length or a different length by unscrewing the hand-tightening bolt, then pulling out the scraper, and then re-screwing the hand-tightening bolt into the corresponding threaded hole on the new scraper, thereby realizing fast and efficient replacement of the scraper, and the operation is more convenient and efficient.

[0007] The adsorption component includes a through hole on the blade plate, in which a suction pipe connected to the air suction port of the vacuum cleaner is inserted, and a dust hood is provided at the other end of the suction pipe and located on the inner side of the blade plate. When the scraper is scraping the rubber on the roller, the vacuum cleaner is started. At this time, the scraped rubber will be sucked into the vacuum cleaner through the dust hood for cleaning, without the need for subsequent manual centralized cleaning operations, which is more efficient and labor-saving.

[0008] The fixed shaft is rotatably arranged between the two fixed plates through the bearing, the fixed plate is provided with a mounting hole matched with the outer ring of the bearing, the outer ring of the bearing is fixed in the mounting hole, a connecting rod is sleeved on the outer side of the fixed shaft, a locking bolt for preventing the connecting rod from rotating is arranged on the connecting rod, an elastic component is sleeved on the other end of the connecting rod, a positioning rod is arranged on the upper part of the elastic component, and the positioning rod is fixed on the fixed plate. The utility model can adjust the inclination angle of the scraper by loosening the locking bolt, then rotating the fixed shaft with the knife plate and the scraper to a suitable angle, and then tightening the locking bolt, so as to facilitate the cleaning operation of the rubber material on the outer side of the roller with rubber materials of different diameters or different thicknesses, which is more convenient and efficient.

The utility model can realize compression of the spring by tightening the nut, and the compressed spring will push the connecting rod with the fixed shaft at the other end of the connecting rod under the action of its own restoring elastic force. Under the combined action of the restoring elastic force of the compressed spring and the scraping resistance of the rubber material on the scraping roller and the action of the adjusting groove, the connecting rod is pushed to swing up, down, left and right, thereby realizing repeated scraping of the colloid on the outer side of the roller.
