Abstract
Description
Technical Field
[0001] The present invention relates to the field of paper reel processing equipment, and specifically to a cutting device for thin paper reels and its usage method. Background Art
[0002] When a paper reel is slit, a web slitter is generally used. As the name implies, a web slitter is a device used to quantitatively cut the flattened and straightened roll paper released from a winding roll; A web slitter is provided in the related art. The web slitter includes a winding roll, a conveyor belt, a pressure roll located above the conveyor belt, and a cutting knife located behind the production line of the pressure roll; When using this web slitter, generally after starting the winding roll, the reel paper wound around the outside of the winding roll is released and placed on the running conveyor belt. The conveyor belt runs to transport the released reel paper. During the transportation of the reel paper, the set pressure roll is used to flatten and straighten the transported reel paper; after the reel paper is flattened and straightened, the cutting knife is pushed to slide by an electric push rod, so that the displaced cutting knife quantitatively cuts the flattened and straightened reel paper; However, the defects of this web slitter are also obvious. For example, limited by the cutting of the up and down displacement of the cutting knife, it can only cut the relatively thick reel paper; for the relatively thin reel paper, when the cutting knife moves up and down for cutting, not only is it easy to lose the shearing force, resulting in the cutting position being ineffective; and even if it can cut the relatively thin reel paper, there are relatively large tooth openings at the later cutting position, the cutting mark position is uneven, and the cutting quality is poor; In view of the problems in the above background art, the present invention aims to provide a cutting device for thin paper reels and its usage method. Summary of the Invention
[0003] The purpose of the present invention is to provide a cutting device for thin paper reels and its usage method to solve the problems raised in the above background art.
[0004] To achieve the above purpose, the present invention provides the following technical solutions: A cutting device for thin paper reels, the cutting device for thin paper reels includes: A base, wherein a shaft wheel frame, a paper pressing frame, and a processing frame are respectively installed on the upper end of the base from left to right; A paper reel for releasing and winding thin paper for subsequent cutting processing is rotatably installed on the shaft wheel frame; A tensioning assembly for automatically tensioning the thin paper released from the outer surface of the paper reel is provided on the paper pressing frame; A conveying assembly for flattening and rectifying the thin paper released from the outer surface of the paper roll while conveying and transporting it is provided on the processing frame; In addition, a cutting assembly for quantitatively cutting and dividing the flattened, rectified, and conveyed thin paper is provided at the outlet position of the processing frame.
[0005] As a further solution of the present invention: A servo motor is installed on the base, and a rotating shaft is provided at the output end of the servo motor. One end of the rotating shaft passes through the axial center position of the paper roll and the axial center position of the shaft wheel frame, and a first shaft wheel is provided at the end.
[0006] As a further solution of the present invention: The tensioning assembly includes a tensioning roller and a slider. The tensioning roller is rotatably installed on the slider; a chute is provided on the surface of the paper pressing frame, and the provided slider is slidably installed inside the chute; at the same time, alignment rods are respectively installed at the upper and lower ends of the slider, and compression springs are sleeved outside the alignment rods.
[0007] As a further solution of the present invention: The conveying assembly includes a feeding belt, a first pressing roller, and a second pressing roller. Feeding wheels are rotatably installed at the front and rear ends of the inner side of the provided feeding belt; both the first pressing roller and the second pressing roller are located above the feeding belt; at the same time, the axial center positions of the first pressing roller and the second pressing roller are connected by a belt; among them, the axial center position of the first pressing roller is also connected to the outside of the first shaft wheel installed on the shaft wheel frame through a transmission assembly.
[0008] As a further solution of the present invention: The transmission assembly includes a toothed disc and a second shaft wheel. The number of toothed discs is two, and the outsides of the two toothed discs are meshed with each other; among them, one toothed disc shares the same pin shaft with the first pressing roller, and the other toothed disc shares the same pin shaft with the second shaft wheel; and the outside of the second shaft wheel is connected to the outside of the first shaft wheel through a transmission belt.
[0009] As a further solution of the present invention: A processing table is provided at the outlet position of the processing frame, and the provided cutting assembly is installed at the processing table position.
[0010] As a further solution of the present invention: The cutting assembly includes a movable block and a cutter. The cutter is obliquely installed on the movable block; at the same time, slide rods are vertically distributed and installed on the processing table, and the provided movable block is slidably installed on the slide rods; in addition, rotating wheels are symmetrically distributed and installed on the processing table, and the outsides of the rotating wheels are connected by a reciprocating belt; the provided movable block is connected to the reciprocating belt.
[0011] The usage method of the above-mentioned cutting equipment for thin paper rolls includes the following steps: S1. Rotate the paper roll to release the wound thin paper; convey and displace the released thin paper along the tensioning assembly installed on the paper pressing frame; S2. The thin paper after tension adjustment enters the position of the conveying assembly installed on the processing rack; while the conveying assembly conveys and displaces the thin paper, it can also flatten and smooth the displaced thin paper. S3. The flattened and smoothed thin paper is quantitatively slit and processed by the rotating cutting assembly.
[0012] Compared with the prior art, the beneficial effects of the present invention are as follows: The cutting device for thin paper rolls has the following advantages compared with the current web slitter: First, it replaces the original quantitative cutting method of pushing the cutting knife to slide and displace by an electric push rod for the flattened and smoothed paper roll through the provided cutting assembly. The provided cutting assembly includes a slider and a cutting knife. The cutting knife is obliquely installed on the slider. The reciprocating displacement of the reciprocating belt driven by the rotating wheel drives the slider to reciprocate, and then the cutting knife installed on the slider reciprocates to perform the cutting operation on the flattened and smoothed thin paper. Since it is a left-right cutting, a better cutting effect can be achieved on the thin paper, and the cut position at the cut is beautiful and neat, and the cutting quality is good. Second, by setting the tensioning assembly, when the tensioning roller of the tensioning assembly rotates to convey the thin paper, the compression springs distributed above and below the slider deform to generate elastic variables, causing the slider to have a slight up and down position offset inside the chute, until finally causing the tensioning roller installed on the slider to have a slight up and down position offset, realizing the automatic tensioning operation adjustment of the thin paper conveyed and displaced along the outer surface of the tensioning roller.
