A feeding guide device for a calender

Abstract

The invention discloses a feed guiding device of a calender. The feed guiding device of the calender comprises a base plate. The front end and the back end of the upper surface of the base plate are each provided with two second supporting plates. A fixed plate is installed among the top ends of the four second supporting plates. An adjusting rod is connected with the middle portion of the fixed plate in a threaded manner. Two sliding rods are connected to the fixed plate in a sliding manner. The two sliding rods are located on the front portion and the back portion of the adjusting rod correspondingly. According to the feed guiding device of the calender, paper is located and guided through an upper guiding plate and a lower guiding plate, so that feed of the calender is facilitated; because of the cooperation between a baffle and the upper guiding plate, the front side and the back side of the paper can be located and limited, when the feed guiding device is used, it is only needed to arrange the right end of the upper guiding plate and the right end of the lower guiding plate on the feed portion of a guiding roller, and then deviation of the paper can be reduced; and because of arc transition plates, the paper cannot generate rigid friction with the right end of the upper guiding plate and the right end of the lower guiding plate, and the paper is protected.

Description

technical field [0001] The invention relates to the technical field of papermaking, in particular to a feeding guide device for a calender. Background technique [0002] Calender is a kind of equipment used to improve the glossiness of paper, and it is a kind of calendering and glazing process. After the surface of the printed matter is coated, the glazing layer is dried. If the smoothness and gloss of the glazing coating need to be improved again, it can be calendered by a calender. Generally, the gloss of glazing is about 65-85%, and it can reach more than 90-95% gloss after calendering. [0003] The most common type of calender is the twin-roll calender. The twin-roll calender mainly includes two calender rollers arranged parallel to each other and a transmission motor that drives the calender rollers to rotate. When in use, the surface smoothness needs to be improved. The paper with high glossiness is placed between the two calender rollers, but because it only depends...

[0003] The most common type of calender is the twin-roll calender. The twin-roll calender mainly includes two calender rollers arranged parallel to each other and a transmission motor that drives the calender rollers to rotate. When in use, the surface smoothness needs to be improved. The paper with high glossiness is placed between the two calender rollers, but because it only depends on the calender rollers for extrusion, the paper will deviate from the left and right after a long calendering time. At this time, the paper can only be readjusted. The location of the position not only seriously affects the calendering efficiency, but also causes the paper to wrinkle or cause uneven thickness due to the uneven calendering of the paper, which in turn affects the quality of the paper
