TECHNICAL FIELD
[0001] The present application relates to the technical field of corrugated paper processing equipment, in particular to a feeding device for corrugated paper board blanks. BACKGROUND
[0002] In the production process of corrugated paper board, the feeding link of the blank is crucial. At present, the common feeding device usually includes a horizontal conveying mechanism and a vertical conveying mechanism, and the direction conversion of the paper board blank is realized through a reversing table between the two to meet the needs of the subsequent processing procedures. However, it is found in actual operation that when the paper roll is moved in the reversing direction at the reversing table, the offset often occurs. This results in that the paper roll cannot be accurately located in the middle position of the reversing table, and further seriously affects the stability and accuracy of the paper roll in the subsequent conveying process. Once the position of the paper roll is offset, not only the problems such as paper jam, paper roll falling, etc. may occur in the conveying process, reducing the production efficiency and increasing the cost of manual intervention, but also the subsequent processing procedures may deviate, affecting the overall quality of the corrugated paper board, and unable to meet the requirements of modern industrialized production for high precision and high efficiency.
