Description

Corrugated paper preheating device for carton production Technical Field The utility model relates to the technical field of preheating devices, in particular to a corrugated paper preheating device for carton production. Background The preheating device is used for preheating corrugated paper for carton production, the corrugated paper production on the market at present uses cardboard and corrugated paper to combine together, the general production flow of corrugated paper is to smear raw rubber in advance between the two, then can become a qualified corrugated paper through preheating and extrusion treatment, the preheating device comprises a mounting bracket, a preheating cylinder, a compression roller, a connector, a chain wheel, a steam rotary joint and a spiral pipe, when the preheating device is used, an external steam pipe is connected with the steam rotary joint, so that steam enters the spiral pipe through the connector, thereby heating the preheating cylinder, then the cardboard and the corrugated paper are adhered through glue and placed between the compression rollers on two sides of the mounting bracket and the preheating cylinder, the chain wheel is connected with the external chain, and the external motor drives the chain wheel to rotate, so that the preheating cylinder rotates, and the corrugated paper for carton production is preheated. The inventor finds that when the preheating device is used in daily work, the corrugated paper is preheated by bonding glue between the paper board and the corrugated paper, but some flowing hot glue exists in the corrugated paper board after the preheating treatment, and the corrugated paper board is extruded to possibly cause excessive glue to flow out to the preheating cylinder, so that the influence of the excessive glue on the corrugated paper is avoided, the glue is generally treated manually, and further the labor intensity is possibly increased. Disclosure of utility model The utility model aims to solve the problems that in the actual use process, the corrugated paper is preheated by bonding glue between a paper board and the corrugated paper, but some flowing hot glue exists in the corrugated paper board subjected to preheating treatment, and the corrugated paper board is extruded to possibly cause excessive glue to flow out to a preheating cylinder, so that the problem that the excessive glue affects the corrugated paper, the glue is generally treated manually to possibly cause the increase of labor intensity is solved. In order to achieve the purpose, the corrugated paper preheating device for the carton production comprises a mounting frame, wherein one end of the mounting frame is provided with a connector which is connected with the mounting frame in a rotating mode through a bearing, a preheating cylinder is fixedly connected between the two connectors, two identical press rolls which are connected with the mounting frame in a rotating mode through the bearing are arranged between the two mounting frames, the two press rolls are distributed on two sides of the preheating cylinder, the lower end of the preheating cylinder is provided with a scraping assembly, the arc surface of the connector is fixedly connected with a chain wheel which is externally connected with a chain, one end of the connector is provided with a steam rotary joint, the inner wall of the preheating cylinder is fixedly connected with a spiral pipe, the spiral pipe is fixedly connected with the connector, the scraping assembly comprises a connecting plate which is fixedly connected between the two mounting frames, the upper end of the connecting plate is inserted with a round rod in a sliding mode, and the upper end of the round rod is fixedly connected with a scraping plate. The scraping assembly is arranged, when glue on the preheating cylinder needs to be scraped, the scraping plate on the circular rod is contacted with the preheating cylinder, and the preheating cylinder is matched with the chain to drive the chain wheel to rotate through the external motor, so that the effect of scraping the glue on the preheating cylinder is achieved as much as possible. Preferably, one end of the round rod is fixedly connected with a first spring, and the other end of the first spring is fixed with the connecting plate. The scraper blade is contacted with the preheating cylinder through the arrangement of the first spring, so that the first spring is in tension, and the scraper blade is fully contacted with the preheating cylinder under the reverse acting force of the first spring. Preferably, the upper end of the connecting plate is penetrated with a screw rod, the screw rod is fixedly connected with the scraping plate, and the arc surface of the screw rod is in threaded connection with a nut. The screw rod is dragged downwards when the scraper is not needed, so that the scraper is separated from the preheating cylinder, and then the nut is screwed, so that the nut is contacted wit
