DETAILED DESCRIPTION

[0019] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0020] like Figure 1-4As shown, a device for forming a stepped catalog of inner pages of a paper book comprises a vertical frame 1 and a horizontal frame 2 which are fixedly connected. A workbench 4 for placing inner pages is arranged on the horizontal frame 2. The workbench 4 is driven by a workbench moving driving mechanism fixed on the horizontal frame 2. As shown in FIG3 , the workbench moving driving mechanism comprises a servo motor 9, a fixing seat 10 and a lead screw 11. The servo motor 9 is fixed on the horizontal frame 2. The lead screw 11 is rotatably connected with the horizontal frame 2, and the lead screw 11 is coaxially fixed with the driving shaft of the servo motor 9. The fixing seat 10 is fixed on the lower surface of the workbench 4. The seat 10 is screwed with the lead screw 11, and two parallel and horizontally arranged rails 12 are fixedly arranged on the transverse frame 2. The two rails 12 are located on the front and rear sides of the fixed seat 10. Two sliders 13 are fixed on the front and rear sides of the fixed seat 10, and the sliders 13 are horizontally slidably matched with the rails 12. The setting of the double rails can ensure the stability of the horizontal movement of the workbench 4 and the accuracy of the direction, improve the punching quality of the inner pages, and control the intermittent horizontal movement of the workbench 4 through the servo motor 9; the workbench 4 is fixedly provided with an inner page fixing component for fixing and positioning the entire inner page, such as Figure 4 As shown, the inner page fixing assembly includes a base 14, a first cylinder 15, a rack 16, a gear 17 and an upper pressing plate 18. The base 14 is fixed on the workbench 4, the first cylinder 15 is fixed on the base 14, the piston rod of the first cylinder 15 is fixedly connected to the rack 16, and is used to drive the rack 16 to move horizontally. A mounting seat 8 is fixedly provided on the base 14, the gear 17 is rotatably connected to the mounting seat 8, the rack 16 is meshed with the gear 17, and connecting rods 21 are coaxially fixed at both ends of the gear 17, and the ends of the connecting rods 21 are rotatably connected to the upper pressing plate 18. When the inner page needs to be pressed, the first cylinder 15 drives the rack 16 to move forward, so that the gear 17 meshing with the rack 16 rotates clockwise, and the gear 17 drives the upper pressing plate 18 to press the inner page downward through the connecting rod 21; and in order to facilitate the positioning of the inner page and make the punching size of the inner page accurate, the inner page fixing assembly also includes a front positioning baffle 20 and a side positioning baffle 19, the front positioning baffle 20 is fixed to the front end of the base 14, and is used to abut against the rear side of the inner page, and the side positioning baffle 19 is fixed on the workbench 4, and is used to abut against the side edge of the inner page;

[0021] A horizontal lower die base 6 is fixedly arranged on the vertical frame 1. There is a gap between the workbench 4 and the lower die base 6. The upper surface of the lower die base 6 is in the same horizontal plane as the upper surface of the workbench 4. An upper die cutter 5 that can slide up and down is arranged on the vertical frame 1. The lower die base 6 is L-shaped. The upper die cutter 5 cooperates with the vacant part of the lower die base 6 to achieve the punching of the inner page to form a catalog. A cutter driving mechanism and a paper pushing assembly are fixedly arranged on the vertical frame 1. The cutter driving mechanism is a second cylinder 22. The second cylinder 22 is vertically fixed on the vertical frame 1. The piston rod of the second cylinder 22 is fixed to the upper die cutter 5; the paper pushing assembly is used to push the inner page after punching downward away from the lower die base 6, and the paper pushing assembly includes a third cylinder 23 and a push plate 24. The third cylinder 23 is vertically fixed on the vertical frame 1, and the push plate 24 is long and narrow. The push plate 24 is fixed to the piston rod of the third cylinder 23. The push plate 24 is located in the gap between the lower die base 6 and the workbench 4 to avoid collision between the push plate 24 and the lower die base 6 and the workbench 4 when moving downward, so that the push plate 24 can smoothly push the punched inner page away from the lower die base 6.

[0022] In addition, a set of safety light curtains 7 can be fixed on the horizontal frame 2. The safety light curtains 7 are located at the left and right ends of the workbench 4. When the hands or other body parts of the staff are close to the upper die cutter 5 and block the infrared light emitted by the safety light curtain 7, the equipment stops immediately to play a role in safety protection. A photoelectric sensor can also be installed on the lower die base 6. When the photoelectric sensor detects that the inner page is placed on the lower die base 6, the second cylinder 22 drives the upper die cutter 5 to move downward.

[0023] In the forming device of the present invention, the control of the action sequence among the safety light curtain 7, the photoelectric sensor, the servo motor 9, the first cylinder 15, the second cylinder 22 and the third cylinder 23 and the control of the emergency stop are all realized by the existing control system.

[0024] The forming process of the stepped catalog on the inner pages of the forming device of the utility model is as follows: a stack of inner pages or bound inner pages are placed on the workbench 4, the rear side of the inner page is pressed against the front positioning baffle 20, and the right side is pressed against the side positioning baffle 19, and then the first cylinder 15 is controlled to work, and the connecting rod 21 is driven to rotate through the meshing of the rack 16 and the gear 17, thereby driving the upper pressing plate 18 to move down and press the inner pages, ensuring the neatness of the inner pages and preventing the inner pages from shifting during the punching process; then the operator flips up the entire inner page and manually delivers the inner pages. The number of inner pages delivered each time can be pre-separated in the inner page book to facilitate the operator's operation. The side edge of the inner page is placed on the upper surface of the lower die base 6. When the photoelectric sensor on the lower die base 6 detects the inner page, the second cylinder 22 drives the upper die cutter 5 to move downward, and cooperates with the lower die base 6 to punch out the inner pages to form a catalog; then the third cylinder 23 drives the push plate 24 to move downward, and pushes the punched inner pages away from the lower die base 6. At the same time, the servo motor 9 drives the workbench 4 to move right for a set distance and then stops (that is, drives the workbench 4 to perform intermittent horizontal movement) through the cooperation of the lead screw 11 and the fixed base 10, and then the operator manually puts in the next batch of punched inner pages. When the photoelectric sensor on the lower die base 6 detects the inner pages, the second cylinder 22 drives the upper die cutter 5 to move downward to punch out the next batch of inner pages. The operation is repeated until the punching of the entire inner page is completed to obtain a stepped catalog; finally, the servo motor 9 drives the workbench 4 to reset, that is, move to the far left, to prepare for the forming processing of the stepped catalog of the next inner page.

[0025] The protection scope of the present invention includes but is not limited to the above embodiments, and its protection scope is subject to the claims. Any replacement, deformation, and improvement of the technology that can be easily thought of by technicians in this field shall fall within the protection scope of the present invention.
