Tipping paper deviation rectifying mechanism

Abstract

A tipping paper deviation rectifying mechanism comprises a wallboard, a paper sensor, a servo motor, a linear guide rail, a deviation rectifying roller assembly and a negative pressure air pipe. The paper sensor is fixedly connected to the front face of the wallboard. The servo motor is fixedly connected to the back face of the wallboard. The servo motor is in signal connection with the paper sensor. An output shaft is arranged at one end of the servo motor and penetrates through the wallboard. The linear guide rail is fixedly connected to the front face of the wallboard. A sliding block is connected to the linear guide rail in a sliding manner. The output shaft is in threaded connection with the sliding block. The deviation rectifying roller assembly is rotationally connected to the end,away from the output shaft, of the sliding block. Through holes are uniformly distributed in the outer wall of a deviation rectifying roller. The negative pressure air pipe is communicated with one end of the deviation rectifying roller assembly, and the other end of the deviation rectifying roller assembly is closed. According to the tipping paper deviation rectifying mechanism, tipping paper isdriven to move front and back to achieve deviation rectification under the action of negative pressure on the deviation rectification roller assembly, it is avoided that mechanical limiting possibly damages the tipping paper, tension in the tipping paper conveying process cannot be changed, and the paper breaking risk is lowered.

Description

technical field [0001] The invention belongs to the field of tobacco machinery, in particular to a tipping paper deflection correction mechanism. Background technique [0002] The high-speed cigarette machine has gradually become the mainstream processing equipment in the cigarette industry due to its high degree of automation, high processing efficiency, and good stability, and has promoted the rapid development of the cigarette industry. However, there are still some problems in the actual use of high-speed cigarette machines, among which the most prominent is the lateral offset of tipping paper in the long-distance transmission process. The lateral offset of the tipping paper will cause the length of the tipping paper at the end of the cigarette branch to be different after cutting, which will directly affect the product appearance, quality and corporate product image. At present, there are two main ways of correcting the tipping paper of the cigarette machine. One is to...

Problems solved by technology

[0003] Manual deviation correction not only affects the efficiency of the machine, but also has poor adjustment effect when the tipping paper fluctuates greatly, which is easy to damage the tipping paper and affect the quality of cigarettes

[0004] Automatic deviation correction detects the deviation of the tipping paper and changes the inclination angle of the correction roller. When the paper guide roller swings, the tension on one side of the tipping paper will increase, which determines that the swing range of the paper guide roller is very small, and the swing The speed is slow, otherwise the tipping paper is easy to break; therefore, this method only works well when the fluctuation of the tipping paper is small, but in the actual production process, the tipping paper often has large fluctuations after the paper is changed. , it is often easy to adjust frequently and reciprocally to achieve the effect. During the adjustment process, a large number of unqualified cigarette products will be produced, which will affect the product quality. Too frequent adjustment will also lead to paper breakage

Current cigarette mainstream cigarette production equipment often uses material stations to supply tipping paper materials. The conveying process is complicated and the distance is long. It takes 5-10 minutes to re-thread the paper each time, which greatly affects the effective operation rate of the equipment.

The current 12,000 pieces of tipping paper are used up every 13 minutes on average in the mainstream models, and splicing and replacement are extremely frequent. If the problem of tipping paper correction is not effectively solved, a large number of unqualified cigarettes will be produced, which will greatly affect production efficiency. Unnecessary waste of production consumption is generated, so it is imminent to solve the problem of tipping paper correction
