TECHNICAL FIELD

[0001] The utility model belongs to corrugated paper production technical field, specifically related to a corrugated paper line pressure self -adaptation deviation rectifying device. BACKGROUND

[0002] In the modern packaging industry, as a kind of widely used packaging material, the production quality and efficiency of carton directly affect the development of the whole industry chain.Corrugated paper machine as the key equipment of carton production, the quality of line pressure process plays a vital role in the forming and subsequent use of carton.

[0003] At present, in the line pressure process of corrugated paper machine, the traditional production mode mainly relies on manual experience and simple mechanical device to carry out line pressure and deviation rectifying operation.In the process of nailing and sticking box, the traditional equipment mostly lacks secondary line pressure and effective line pressure deviation rectifying function.For the monitoring of corrugated paper position, usually simple sensor or completely relying on manual regular inspection is adopted, and real-time dynamic monitoring of corrugated paper in production process cannot be realized.Due to the lack of secondary line pressure and effective line pressure deviation rectifying function, the traditional nailing and sticking box process is prone to line pressure defect in the line pressure process.Once line pressure is inaccurate, in the subsequent nailing and sticking box process, carton is prone to misplacement phenomenon, which seriously affects the qualified rate of product.

[0004] In view of this, we propose a corrugated paper line pressure self-adaptive deviation rectifying device to solve the above problems. CONTENT OF UTILITY MODEL

[0016] As a preferred, the two-axis screw linear slide module comprises a longitudinal screw linear module and a transverse screw linear module fixed on a longitudinal slide table of the longitudinal screw linear module, and the motorized turntable is fixed on a transverse slide table of the transverse screw linear module.

[0019] Compared with the prior art, the technical effects and advantages of the utility model are:

[0020] The corrugated paper line pressing self-adaptive deviation correcting device, the photoelectric sensor is installed above the conveying belt of the automatic conveying line, real-time detects the position information of the corrugated paper in the transmission process, covers the transverse offset, speed and tension information and the like.These data are transmitted to the PLC controller, the PLC controller processes the received signals, and according to the internal deviation correcting algorithm, calculates the direction and amplitude of the corrugated paper needing to be corrected, and then outputs the deviation correcting control signal.The actuator is installed on the rack of the automatic conveying line and is located on both sides of the corrugated paper, after receiving the signal of the PLC controller, drives the servo motor on the two-axis screw linear slide module and the servo motor on the electric turntable to act.The two-axis screw linear slide module drives the deviation correcting plate to move left and right and forward and backward, the electric turntable drives the swing plate to swing to adjust the angle of the deviation correcting plate, so as to accurately adjust the transverse position of the corrugated paper from both sides thereof.Meanwhile, the man-machine interface can set and display the equipment parameters and provide operation feedback, and the alarm gives an alarm when detecting an abnormal condition.

[0021] The corrugated paper line pressing self-adaptive deviation correcting device greatly improves the production quality.In the traditional process, the line pressing is poor and the corrugated paper offset problem is common, which leads to the paper box misplacement and high scrap rate.The device can detect and correct the small deviation in time by real-time monitoring the accurate position of the corrugated paper through the photoelectric sensor and combining the intelligent algorithm of the PLC controller, and the deviation error of the corrugated paper is controlled within ±1mm, which ensures the accuracy of the line pressing position and effectively improves the quality standard of the product, effectively reduces the scrap rate and greatly reduces the production loss.
