Description

Technical Field

[0001] This utility model belongs to the field of box gluing machine technology, and in particular relates to a paper feeding mechanism. Background Technology

[0002] In the packaging and printing industry, the application of box gluing machines is the final step in packaging box processing. It involves folding and gluing printed and die-cut cardboard into shape. Machine gluing replaces manual gluing, reducing labor costs and improving efficiency.

[0003] Existing gluing machines generally include a paper feeding mechanism, a correction mechanism, a pre-folding mechanism, a bottom hooking mechanism, and an output mechanism. The paper feeding mechanism is used to transport stacked papers one by one. Currently, the paper feeding mechanism cannot be adjusted up and down as a whole; it can only be adjusted by individual paper feeding blade mechanisms and individual paper feeding baffle mechanisms, which is a rather cumbersome adjustment process.

[0004] In view of this, the present invention aims to provide a paper feeding mechanism that, through a clever structural design, can simultaneously adjust the vertical position of the paper feeding knife mechanism and the paper feeding baffle mechanism, thereby improving adjustment efficiency. Moreover, this paper feeding mechanism can adapt to the feeding of paper of various sizes, thus having higher compatibility. Utility Model Content

[0005] The purpose of this utility model is to provide a paper feeding mechanism that addresses the shortcomings of existing technologies. Through its ingenious structural design, it can simultaneously adjust the vertical positions of the paper feeding knife mechanism and the paper feeding baffle mechanism, thereby improving adjustment efficiency. Moreover, this paper feeding mechanism can adapt to the feeding of paper of various sizes, thus having higher compatibility.

[0006] To achieve the above objectives, this utility model adopts the following technical solution: a paper feeding mechanism, including a conveying mechanism, a paper feeding feeder mechanism above the conveying mechanism, and lifting drive mechanisms on both sides of the conveying mechanism. The two lifting drive mechanisms can drive the entire paper feeding feeder mechanism to move up and down. The up-and-down movement of the paper feeding feeder mechanism can adjust the positions of the paper feeding blade and the paper feeding baffle. The conveying mechanism includes multiple sets of conveyor belt mechanisms arranged at intervals. The conveyor belts on the multiple sets of conveyor belt mechanisms are driven by a belt drive rod, one end of which is driven by a motor.

[0007] As an improvement of the paper feeding mechanism of this utility model, the lifting drive mechanism includes an installation platform, on which a cylinder and a buffer spring mounting seat are provided. The piston rod end of the cylinder is connected to the paper feeding feeder mechanism, and a spring mounting rod is provided on the buffer spring mounting seat, with a buffer spring sleeved on the spring mounting rod.

[0008] As an improvement to the paper feeding mechanism of this utility model, the paper feeding feeder mechanism includes two correspondingly arranged side plates. A connecting platform is provided on the outer surface of each of the two side plates. The piston rod end of the cylinder is connected to the connecting platform, one end of the buffer spring abuts against the bottom of the connecting platform, and the spring mounting rod passes through the connecting platform. The buffer spring has two functions: first, it provides gravity buffering for the entire paper feeding feeder mechanism when it descends; second, it provides lifting assistance when the cylinder holds the entire paper feeding feeder mechanism in place.

[0009] As an improvement to the paper feeding mechanism of this utility model, the outer side of the side plate is also provided with a slider, and the two sides of the conveying mechanism are respectively provided with slide rails, which cooperate with the slider.

Both the paper feeding baffle mechanism and the paper feeding knife mechanism are slidably adjustable on the first connecting beam and the second connecting beam via a transverse slider. Two paper feeding knife mechanisms can be provided, with one as a spare. When feeding larger sizes of paper, both paper feeding knife mechanisms can be used simultaneously. When feeding smaller sizes of paper, the spare paper feeding knife mechanism can be disassembled. It can accommodate paper with a minimum length of approximately 35mm.

[0012] As an improvement of the paper feeding mechanism of this utility model, the paper feeding feeder mechanism further includes a first paper feeding baffle adjustment drive and a second paper feeding baffle adjustment drive for controlling the distance between the two paper feeding baffle mechanisms. The first paper feeding baffle adjustment drive controls the left and right position of one of the paper feeding baffle mechanisms, and the second paper feeding baffle adjustment drive controls the left and right position of the other paper feeding baffle mechanism.

When the screw is removed, the entire paper feeding knife mounting base can be separated from the paper feeding knife connecting base. The paper feeding knife mechanism adopts a portable assembly and disassembly method, which is convenient and allows for quick disassembly and assembly of a spare paper feeding knife mechanism. When feeding small-sized paper, a spare paper feeding knife mechanism is reserved to achieve minimum size adjustment.

[0018] The paper feeder connecting seat is provided with a second lead screw nut and a plurality of second lead screw through holes, and the second transmission lead screw is screwed to the second lead screw nut.
