When the paper hemming device is used, the paper hemming device is matched with a paper roll to be used, and the paper roll is pressed between the rolling shaft and the base. The paper roll is sleeved on the paper shaft and is arranged at intervals with the paper tape positioning and conveying mechanism, the paper tape positioning and conveying mechanism 10 is continuously fed, and the feeding structure of the paper roll is common to those skilled in the art and is not described in detail herein.

The paper tape positioning and conveying mechanism 10 comprises a base 11, a roller 12 arranged on the base 11, and a positioning part 13 arranged on the base 11 and used for positioning the paper tape at the top of the base 11. A gap is arranged between the roller 12 and the base 11, and the upper side and the lower side of the paper tape respectively prop against the roller 12 and the base 11. When the roller 12 rotates under control, the roller 12 drives the paper tape to move, and the paper tape is continuously fed into the cut-and-folded edge 20. The positioning portion 13 includes three guide rails 131 horizontally arranged at intervals, and two movable positioning blocks 132 slidably sleeved on the guide rails 131. The bottom of the movable positioning block 132 abuts against the top of the base 11, so that the paper tape can be limited to move in the space between the two movable positioning blocks 132, and the moving path of the paper tape can be further limited. By adjusting the positions of the two movable positioning blocks 132, and the distance between the two movable positioning blocks 132, the path of the paper tape can be changed. Obviously, a plurality of movable positioning blocks 132 can be arranged, so that the transmission of a plurality of paper tapes is realized, and the flanging efficiency can be further improved. The movable positioning block 132 is detachably fixed on the outside of the guide rail 131 through a bolt, when the bolt is unscrewed, the movable positioning block 132 can slide on the guide rail 131, and when the bolt is screwed down, the movable positioning block 132 is fixed on the guide rail 131.

The cut-and-folded portion 20 includes a slice driving assembly 21 provided on the base 11 and reciprocally moving in a direction perpendicular to a surface of the base 11, a mounting portion 22 provided at a driving end of the slice driving assembly 21, a cutting assembly 23 provided at a bottom of the mounting portion 22, and a folded portion 24 provided on the mounting portion 22.

The slice driving assembly 21 may be a ball screw or a hydraulic cylinder or an air cylinder. The drive end of the slice drive assembly 21 continues to reciprocate toward and away from the base 11. The number of the slice driving assemblies 21 is two, and the slice driving assemblies are respectively arranged at two sides of the roller 12, so that the movement of the mounting portion 22 can be ensured to be stable, the operation of the cutter main body 231 described below is ensured to be stable, and meanwhile, the notch 2412 of the positioning sleeve 241 described below can be ensured to be kept in a vertical state, and the phenomenon that the quality of folding edges is influenced due to the dislocation of the notch 2412 and the top core 243 caused by the inclination of the mounting portion 22 is avoided.

The cutting assembly 23 comprises a cutter body which is arranged perpendicular to the top surface of the base 11. The end of the cutter body is lower than the bottom end of a positioning sleeve 241 described below, so that the paper tape can be cut off before folding. The cutting assembly 23 is disposed between the paper tape positioning and conveying mechanism 10 and the hemming assembly 24.

The hemming assembly 24 includes a positioning sleeve 241 disposed at one side of the mounting portion 22, a mounting groove portion 242 disposed around the base 11, and a top core 243 disposed on the mounting groove portion 242. The hemming assembly 24 is disposed on a side of the mounting portion 22 facing away from the tape positioning and transporting mechanism 10.

The positioning sleeve 241 comprises a sleeve body 2411, a notch 2412 arranged on the sleeve body 2411 and vertically penetrating through the sleeve body 2411, and a baffle plate 2413 and a guide plate 2414 respectively arranged on the top of the sleeve body 2411 and positioned on two sides of the notch 2412. The sleeve 2411 is detachably connected with the mounting portion 22 by bolts, so that the sleeve 2411 with different sizes can be replaced according to different hemming size requirements. The cross-section of the slot 2412 is rectangular and cooperates with the top core 243, and the specific structure will be described below in conjunction with the top core 243. The baffle 2413 is disposed on one side of the notch 2412, and is used for blocking the folded product from falling back to the base, and cooperating with the guide plate 2414 to guide the processed product, so as to avoid the product from falling into the position of the cutting assembly 23 and affecting the processing.

The mounting groove 242 is provided on one side of the tape positioning and transporting mechanism 10. The mounting groove 242 is a horizontal plane having a height difference from the top of the base plate 11. The cutter assembly 23 is positioned above the mounting slot 242 so that the end of the cutter body can be moved downwardly beyond the end face of the base 11 to sever the paper strap, i.e. the cutter body can extend below the top of the base 11 to sever the paper strap flush with the top of the base 11.

The top of the top core 243 is flush with the top of the base 11, so that the paper tape is transported to the top core 243 without a drop in height, and the paper is prevented from being bent due to the drop, so that the length of the paper tape cut each time is uneven. It should be noted that, because the paper tape itself has a certain strength, the suspension at a short distance does not cause the paper tape to bend significantly.

The top core 243 includes a top core main body 2431, a plug-in portion 2432 disposed on the top of the top core main body 2431, at least one positioning rod 2433 disposed on the top core main body 2431, and a fixing seat 2434 for fixing the positioning rod 2433. The plugging portion 2432 is columnar, and the cross-sectional shape of the plugging portion 2432 is slightly smaller than the shape of the notch 2412, that is, the two shapes are similar, so that when the plugging portion 2432 is plugged into the notch 2412, a gap exists between the plugging portion 2432 and the notch 2412, a single-layer paper sheet can just pass through the gap 2421, and when the plugging portion 2432 covers the paper sheet, the paper sheet can just pass through the notch 2421 and be folded. It should be noted that, when the slice driving assembly 21 moves to the closest point to the base 11, the positioning sleeve 241 moves with the slice driving assembly 21 to the position closest to the base 11, the end of the plugging portion 2432 penetrates the notch 2412, and when the slice driving assembly 21 moves to the furthest point from the base 11, the positioning sleeve 241 moves with the slice driving assembly 21 to the position furthest from the base 11, and the plugging portion 2432 is spaced from the sleeve body 2411. When the slice driving assembly 21 moves to a position closest to the base 11, the end of the plugging portion 2432 exceeds the positioning sleeve 241 by at least 2cm, so that stable bending can be ensured. And the size of the folded edge is generally not more than 2cm, so that the folded paper sheet can be ensured to be separated. The fixing seat 2434 is detachably mounted on the base 11 through a bolt, and the positioning rod 2433 is inserted on the base 11 and fixed with the base 11 through a bolt. The fixing seat 2434 is detached from the base 11 and the top core with different sizes is replaced, so that the fixing seat 2434 can be matched with the positioning sleeve 241 with different sizes to fold edges with different specifications.

The principle of the positioning sleeve 241 and the top core 243 cooperating with each other to fold edges is as follows: the sliced paper is positioned at the top of the plug-in connection 2432, and two ends of the paper respectively exceed the top of the plug-in connection 2432. When the plug 2432 enters the slot 2412, the part of the paper at the top of the plug 2432 will keep horizontal, and the two ends of the paper that protrude from the plug 2432 will fold down and abut against the side wall of the plug 2432 under the action of the inner wall of the slot 2412 of the positioning sleeve 241 until the end of the plug 2432 protrudes out of the slot 2412. At this time, the folded-down portion of the paper is separated from the side wall of the socket 2432 by losing the pressing of the inner wall of the slot 2412. The positioning sleeve 241 will then be away from the base 11, the plug 2432 will be removed from the slot 2412, and the folded sheet will remain on top of the positioning sleeve 241 because it cannot pass through the slot 2412.

When in use: the web positioning and transporting mechanism 10 continues to feed, and the web will run horizontally to the top of the mounting slot 242 and be cut and hemmed at the mounting slot 242. The specific cutting and flanging process is as follows: the end of the paper tape is first sent to the top of the top core 243, the slice driving assembly 21 moves downward and drives the cutting assembly 23 and the positioning sleeve 241 to move, the cutter body of the cutting assembly 23 first contacts the paper tape and cuts the paper tape, and the positioning sleeve 241 is sleeved on the top of the top core 243, so that the two ends of the cut paper tape are folded downward. The folded paper tape will be pulled out from the top of the positioning sleeve 241, and then the slice driving assembly 21 moves upward to complete one cut and fold.

Compared with the prior art, the paper flanging device provided by the utility model realizes slicing and flanging of paper tapes by arranging the slicing and flanging mechanism 20, wherein the slicing and flanging mechanism 20 comprises the slicing driving assembly 21, the cutting assembly 23 arranged at the driving end of the slicing driving assembly 21 and the flanging assembly 24 arranged at the driving end of the slicing driving assembly 21, and the cutting assembly 23 and the flanging assembly 24 are simultaneously driven by the slicing driving assembly 21 so as to simultaneously cut and flanging the paper tapes, thereby avoiding dislocation of sliced paper sheets in the transportation process due to interval arrangement of slicing and flanging.
