Description

A papermaking roller position control device

Technical Field

The utility model relates to the technical field of papermaking machinery, in particular to a pressure roller position control device for papermaking.

Background Art

Papermaking technology is the process of making paper from cellulose and other fiber materials by wet or dry methods. The press roller used in the papermaking process is an important equipment that mainly plays the role of squeezing pulp and paper. The press roller is usually made of metal materials, such as cast iron and steel.

According to a Chinese patent with announcement number: CN203654083U, a papermaking roller position control device is disclosed. The controller determines whether the production line is shut down based on the detection information of the speed detector. If it is confirmed that the entire production line is shut down, a control signal is sent to the pneumatic device of the entire production line. The pneumatic device supplies air to the cylinder, causing the cylinder to extend the piston rod, and drags the pressure roller through the roller component to lift the pressure roller so that a certain gap is maintained between the pressure roller and the drying cylinder.

In the above scheme, the controller determines whether the production line is shut down based on the detection information of the speed detector. When the shutdown occurs, the cylinder drives the roller component to lift the pressure roller, resulting in the following disadvantages: when the processed paper is of different sizes and thicknesses, if the distance between the pressure roller and the drying cylinder cannot be adjusted, it may cause burns to the paper.

Preferably, the outer wall fixing sleeve of the pulling column is provided with a protective sleeve, and the outer wall of the protective sleeve is provided with anti-slip grooves.

Compared with the prior art, a papermaking roller position control device using the above technical solution has the following beneficial effects:

1. During use, the staff first places the paper on the felt, then passes the felt through the roller body, adjusts the position of the drying rack, and then dries the wet paper through the drying cylinder. During drying, the position of the roller body is adjusted according to the thickness of the paper to avoid damage to the paper due to too close distance. During drying, the speed detector is used to determine whether the production line has a fault and stops, and the temperature sensor is used to monitor the temperature during drying to avoid excessive temperature. When the production line fails and the drying temperature is too high, the staff can directly hold the pulling column to pull the adjustment block backward, so that the support plate and the roller body can be kept away from the drying cylinder. Therefore, the position of the roller body can be quickly adjusted during drying, ensuring that the paper is dried thoroughly and the safety of the paper and the felt is also guaranteed.

2. During use, the electric push rod is driven by the PLC controller, so that when a fault occurs in the production line, the adjustment block can be immediately pushed by the electric push rod, so that the roller body can be quickly moved away from the drying cylinder, thereby improving safety and reducing losses. The infrared sensor can be used to scan whether there is paper placed on the roller body. If there is no paper, the drying cylinder can be directly closed, thus avoiding the drying cylinder from baking the device, thereby saving the cost of use. The sliding of the moving block and the moving groove can stably move the drying rack to avoid the drying rack from being skewed, so that the corresponding position of the drying cylinder and the paper is more neat, thereby improving the drying effect;

3. During use, the alarm can be used to promptly sound an alarm to remind the staff when a fault occurs on the production line, so that the staff can promptly inspect and maintain the production line to avoid delays in production time. The protective cover can provide a stable and comfortable support point for the staff's hands when adjusting the position of the roller body, preventing the staff from falling off when holding the pulling column, thereby improving stability.
