Release the sheets away from each other. The linear direction of the mutual movement of the two clamping plates 15 is parallel to the moving direction of the angle device 1 .

In view of the above and in conjunction with the accompanying drawings, the process of glue binding of the binding machine 100 of the present invention will be described in detail below, as follows:

First, a piece of paper is placed between the two clamping plates 15 , and the lower edge of the piece of paper is aligned with the surface of the platform 5 . At this time, the paper clip motor 12 is started, and the lead screw of the lead screw nut mechanism 14 is driven to rotate by the transmission of the gear chain transmission mechanism 13, the lead screw drives the nut to move, and the nut drives the splint 15 to move, so that the two The clamping plates 15 are close to each other, thereby clamping the paper sheet.

After that, the lift drive mechanism 7 drives the platform 5 to descend. Specifically, the servo motor 71 is activated to drive the belt drive pulley 722 to rotate, the belt drive pulley 722 drives the belt 723 , the belt 723 drives the belt driven pulley 721 to rotate, and the belt driven pulley 721 The nut 74 is driven to rotate, the nut 74 drives the screw rod 73 to rotate, and the screw rod 73 can descend and drive the platform 5 to descend.

Next, the motor 41 of the translation drive mechanism 4 is started, the motor 41 drives the gear 42 to rotate, the gear 42 drives the rack 43 to move, and the rack 43 drives the paper clamping device 1 from the platform The upper part of 5 moves to the upper part of the gluing device 2 . During the moving process, the shutter 9 is retracted into the receiving space 8a along the sliding rail 87 .

When the paper clamping device 1 is located above the gluing device 2, since the heater 26 heats the glue in advance, the glue in the glue tank 24 is in a molten state, and the glue has flowed into the glue tank 24. inside the glue tank 213. At this time, the motor 222 is started, and the motor 222 drives the driving gear 223 to rotate; the driving gear 223 drives the linkage gear 225 to rotate; the linkage gear 225 drives the two small gears through the linkage shaft 226 The gear 227 rotates; the pinion 227 drives the two driven gears 224 to rotate; the driven gear 224 drives the cam 228 to rotate; the cam 228 rolls against the abutting edge 232 and pushes the The lift bracket 23 ascends. The lifting bracket 23 drives the gluing member 21 and the gluing plate 25 to rise at the same time, and the gluing member 21 is close to the lower edge of the paper sheet. The paper separating portion 211 of the gluing member 21 can be inserted into the inner side of the stacked paper sheets, so as to create a gap at the lower edge of the stacked paper sheets. When the paper sheet extends into the gluing groove 213 and the paper is immersed in the glue in the gluing groove 213 , the glue can enter the inner side of the lower edge of the paper sheet from the gap, so that the glue can be inserted into the gluing groove 213 glue onto the paper. After the cam 228 rotates for one week, the cam 228 drives the lifting bracket 23 to rise and then descend, so as to lower the gluing member 21 and the gluing plate 25 into the glue tank 24 . When the pressing plate 25 descends into the glue tank 24 , the bottom surface of the pressing plate 25 will press the glue to both sides, and the glue on one side will flow into the upper surface through the gap 251 . into the glue tank 213 , so as to replenish the glue to the upper glue tank 213 . After the paper is glued. The translation drive mechanism 4 drives the paper clipping device 1 to move back to the top of the case binding device 3 , and at the same time, the paper clipping device 1 drives the shutter 9 to extend and re-shield the gluing device. 2 above.

During the gluing process, the user can place the cover on the platform 5 and align the reference plate 83 , and at the same time clamp the cover by the positioning device 36 to position the cover. After that, the lift drive mechanism 7 drives the platform 5 to rise. Since the glue has a certain thickness after gluing, about 1mm to 3mm, the level reached by the platform 5 should be 1mm to 3mm lower than the original level when it is aligned with the paper, so as to accommodate the glue . When the platform 5 is raised to the right position, the motor 31 starts to drive the drive gear 32 to rotate, and the drive gear 32 drives the two racks 33 to approach each other, so that the two racks 33 drive their respective clamping blocks 34 close to each other. At this time, the two clamping blocks 34 can wrap the cover on the edge of the paper sheet, the paper sheet and the cover are glued together with the curing of the glue, and the binding is completed.

Compared with the prior art, in the present invention, the case binding device 3 and the gluing device 2 are arranged in a horizontal direction, so that the case binding device 3 and the paper clamping device 1 are arranged in a vertical direction. The platform 5 is located below the paper clamping device 1, and the case binding device 3 is arranged on the platform 5. Therefore, the platform 5 can be used as a mechanism for aligning paper sheets when the paper clamping device 1 clamps paper. The reference platform 5 can be used as a positioning platform 5 for positioning the cover during cover binding. Using the same platform 5 before and after glue binding can avoid the need to manually adjust the height difference between the two platforms 5 when using different platforms 5. The earth facilitates the adjustment operation of the staff. In addition, since the case binding device 3 and the paper clipping device 1 are arranged vertically, the horizontal space occupied by the whole machine can be reduced, the structure layout can be made more compact, and the volume of the whole machine can be effectively reduced, so as to be suitable for offices place.

What is disclosed above is only a preferred example of the present invention, of course, it cannot limit the scope of rights of the present invention, so the equivalent changes made according to the scope of the patent application of the present invention still belong to the scope covered by the present invention.
