[0004] Although the above patents can solve the corresponding technical problems, they still have certain defects:

[0005] When the position of the guide roller needs to be adjusted according to the thickness of the support plate, the two adjusting screws need to be turned separately. If the movements are inconsistent during the turning process, it is easy to cause the guide roller to tilt, resulting in the guide roller being unable to effectively convey the cardboard after the cardboard rises to a predetermined height, thereby reducing the conveying effect of the cardboard. Utility Model Content

[0006] The utility model aims to address the defects and shortcomings of the prior art and to provide a cardboard introduction device for a carton printing machine which is not likely to cause the guide roller to tilt, can effectively convey the cardboard after the cardboard rises to a predetermined height, and improves the conveying effect of the cardboard.

[0007] To achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a cardboard introduction device for a carton printing machine, comprising a material storage part for placing cardboard, and also comprising two mounting plates symmetrically arranged at the left and right ends of the material storage part, two longitudinal columns longitudinally arranged on the two mounting plates, a transverse column arranged at the upper ends of the two longitudinal columns and located between the two longitudinal columns, a lifting rack that can be lifted and arranged between the two longitudinal columns and below the transverse column, a material guide roller rotatably arranged at the lower end of the lifting rack, and a material guide roller arranged at the side end of the lifting rack and connected to the material guide roller. A rotating motor for driving the material guide roller to rotate, at least two tension springs symmetrically fixedly arranged between the upper end of the lifting rack and the lower end of the transverse column, a through hole opened at the middle end of the transverse column, a driving screw threadedly connected to the transverse column and located in the through hole, and a guide anti-deviation device arranged between the lifting rack and the transverse column, the upper end of the driving screw passes through the through hole and is located above the transverse column, the lower end of the driving screw abuts against the upper end surface of the lifting rack, and the upper end of the driving screw is provided with a driving handle for facilitating the manual rotation of the driving screw.

[0008] A further improvement is that the guide anti-deviation device includes two guide openings symmetrically opened on the transverse column, a guide slide column whose lower end is fixedly arranged on the lifting rack and whose upper end is gap-matched with the guide opening, and an auxiliary component arranged between the transverse column and the guide slide column and located in the guide opening for preventing the guide slide column from tilting in the guide opening when the guide slide column is lifted or lowered in the guide opening.

[0009] A further improvement is that the auxiliary part includes a first slot opened on the transverse column on one side of the guide slide column, a second slot opened on the transverse column on the other side of the guide slide column, and guide wheels rotatably arranged on the transverse column in the first slot and the second slot, respectively, and the first slot and the second slot are staggered up and down.

[0010] A further improvement is that a contact plate is provided at the lower end of the driving screw rod for increasing the contact area of ​​the driving screw rod with the lifting rack.

[0011] A further improvement is that an elastic contact plate is arranged at the end of the contact plate close to the lifting rack.

[0012] A further improvement is that the elastic contact plate is a rubber plate.

[0013] After adopting the above technical scheme, the beneficial effect of the utility model is as follows: when it is necessary to adjust the position of the guide roller according to the thickness of the support plate, the driving handle is held by hand and rotated, thereby driving the driving screw to descend on the perforation. At this time, the lower end of the driving screw pushes downward against the lifting rack to drive the guide roller to descend. The tension spring can keep pulling the lifting rack to press against the lower end surface inside the driving screw, and drive the lifting rack to rise together when the driving screw rises. During the lifting process of the lifting rack, the guiding biasing device can prevent the lifting rack from tilting, so that the guide roller can maintain a horizontal state continuously. After the cardboard rises to a predetermined height, the cardboard can be effectively conveyed, thereby improving the conveying effect of the cardboard.

[0014] Further effect: during the lifting process of the lifting rack, the guide slide column is lifted and lowered in the guide opening, and the gap between the guide slide column and the guide opening is used to reduce the tilting phenomenon of the lifting rack, so that the lifting of the lifting rack can be effectively guided.

[0015] Further effect: by staggered guide wheels, the two ends of the guide slide column are limited respectively, so that the guide slide column is less likely to tilt in the guide opening, thereby making it less likely for the lifting rack to tilt, which can effectively improve the lifting stability of the lifting rack, and the guide wheels can reduce the sliding resistance of the guide slide column in the guide opening, thereby improving the lifting smoothness of the lifting rack.

[0016] Further effect: the elastic contact plate can reduce the damage caused when the driving screw rod abuts against the upper end surface of the lifting rack. BRIEF DESCRIPTION OF THE DRAWINGS
