Plating press of improved structure

Abstract

The invention relates to the technical field of plating presses, especially to a plating press of an improved structure. The plating press comprises a frame and a felt wrapped roll. The felt wrapped roll is connected to the frame. The felt wrapped roll comprises a top roller and a bottom roller. The plating press further comprises a roller gap adjusting system used for adjusting the gap between the top roller and the bottom roller, and a double motor apparatus. The felt wrapped roll is in driven connection with the double motor apparatus. The roller gap adjusting system comprises a PLC control system and a hydraulic pressure station. The hydraulic pressure station is connected with the felt wrapped roll. The PLC control system and the hydraulic pressure station are electrically connected. With the plating press of the improved structure of the invention, paper joints can automatically pass through the pressing zone of the felt wrapped roll, the artificial link of manual operation is decreased, the press polish effect of paper is effectively improved, and the labor intensity is reduced. The plating press of improved structure of the invention is characterized by a high automation degree and high production efficiency. The paper through the roll compacting of the plating press of the improved structure of the invention has a good quality, and the paper smoothness is much higher than the superior grade standard prescribed by national GB / T16797-2008.

Description

technical field [0001] The invention relates to the technical field of calenders, in particular to a calender with improved structure. Background technique [0002] At present, in the paper production line, the calender is the key equipment that ultimately determines the quality of paper and continuous production. When the calender in the prior art is threading the paper, if there is a joint in the paper web, the calender rolls cannot be separated and the joint is forced to be pressed. Because most of the joints are bonded by adhesive tape, the tape will The entanglement on the roll surface will lead to failure of normal production, and in severe cases, it will damage the equipment. In order to solve this problem, people have improved the structure of the calender so that the calender roll can be separated so that the paper web joint can pass through the calender smoothly. [0003] The Chinese Utility Model Patent No. 201020564635.1 discloses a heavy-pressure cardboard cale...

AI Technical Summary

Problems solved by technology

However, when the calender is manually adjusted to form a roll gap, the calender roll is lifted with high labor intensity, cumbersome operation, slow and unstable lifting speed, and manual operation is required after the roll gap is generated. There are potential safety hazards, time-consuming and labor-intensive, low degree of automation, and low production efficiency; and the power component of this calender is a motor connected to the top roll, and manual adjustment makes the top roll and bottom roll When the roll gap is formed, the top roll and the bottom roll are separated and their linear speeds are not consistent. After the paper web joint passes through the roll gap smoothly, the top roll and the bottom roll are rolled together. At this time, they are pressed between the top roll and the bottom roll Due to the inconsistent linear speed of the top roll and the bottom roll when the paper web is rolled together, the calendering effect of the paper web is poor, the quality of the product is poor, and it does not meet the production requirements, and even the stress distribution on the surface of the paper web is easy to be uneven, which is easy Causes paper breaks, also leads to failure of normal production and low operating efficiency
