Description

Technical Field

[0001] The invention relates to the technical field of book post-printing binding equipment, in particular to a side gauge inclination adjustment mechanism for a sealing device. Background Art

[0002] Book post-printing perfect binding is a binding method that glues the printed pages and covers together into a book. It is common in soft-cover paperback books. The process includes book binding, spine roughening, gluing, cover gluing and cutting. Perfect binding is divided into hot melt binding, PUR binding and cold binding. It has the advantages of high efficiency, low cost and neat appearance, but its durability and flipping angle are limited. It is suitable for publications such as textbooks, novels and magazines. Perfect binding equipment is required in the perfect binding process.

[0003] In the book post-printing binding equipment, the quality of the finished book depends on the performance of each mechanism in the binding equipment. The upper sealing device is responsible for cover transportation and cover pressing. The working quality of the two determines the performance of the upper sealing device. In order to ensure the quality of cover transportation and prevent the cover from rotating and drifting horizontally during transportation, side gauges are generally added to both sides of the cover for positioning and support during transportation. When the cover is transported, it will slightly contact and rub against the side gauges on both sides, so the cover can only be forced to move along the direction of the side gauges, thereby ensuring the quality of cover transportation;

[0004] The current mainstream side gauge mechanism design only has the opening (the distance between the two side gauges) adjustment but no inclination adjustment. Under the influence of manufacturing errors and assembly errors, the side gauges will actually become skewed. Moreover, when the machine works for a long time, the wear of the opening adjustment mechanism and the continuous vibration of the machine will aggravate the skewness of the side gauges, thereby affecting the quality of cover transportation, causing the skewed cover to eventually enter the cover pressing process, which further leads to skewness in the pressing process, ultimately affecting the quality of the finished bound book. Summary of the invention

[0035] The opening adjustment component 25 includes a servo motor 24, which is installed on one side of the exterior wall panel 23. The servo motor 24 is used to provide driving force. The output end of the servo motor 24 is fixedly connected to a driving sprocket 4, which is fixed to the output end of the servo motor 24. After the servo motor 24 is started, the driving sprocket 4 will be controlled to rotate. The opposite ends of the two moving components 28 are fixedly connected to a double-row sprocket 7, and the opposite ends of the other two moving components 28 are fixedly connected to a driven sprocket 9.

[0037] Please refer to the attached Figure 4 , Attachment Figure 6 , Attachment Figure 8The moving assembly 28 includes a trapezoidal thread screw 11, which is arranged inside the outer wall panel 23. Two double-row sprockets 7 are respectively fixedly connected to the opposite ends of the two trapezoidal thread screws 11. The trapezoidal thread screw 11 is installed inside the outer wall panel 23 and rotates inside the outer wall panel 23. The trapezoidal thread screw 11 connected to the trapezoidal thread double-row sprocket 7 will correspondingly control the rotation of the trapezoidal thread screw 11 when the double-row sprocket 7 rotates. The two driven sprockets 9 are respectively fixedly connected to the opposite ends of the other two trapezoidal thread screws 11. The trapezoidal thread screw 11 connected to the driven sprocket 9 will rotate together when the driven sprocket 9 rotates. The outer peripheral thread of the trapezoidal thread screw 11 The groove is connected with a nut slider 12, and the nut slider 12 is threadedly connected to the trapezoidal thread lead screw 11. When the trapezoidal thread lead screw 11 rotates, the nut slider 12 can be driven to move.

The outer side gauge 21 and the inner side gauge 22 are respectively installed on the top of each nut slider 12. When the nut slider 12 moves, the outer side gauge 21 and the inner side gauge 22 can be driven to move accordingly.

[0038] Please refer to the attached Figure 5 , Attachment Figure 7 , Attachment Fig. 9 , Attachment Fig.10 The transmission assembly 27 includes two driving gears 17, which are respectively fixedly connected to the left and right ends of the inclination adjustment shaft 20. The driving gear 17 is connected to the inclination adjustment shaft 20. When the inclination adjustment shaft 20 rotates, the driving gear 17 can be driven to rotate accordingly. The outer periphery of the trapezoidal thread screw 11 is provided with a thread sleeve 16, and the outer periphery of the thread sleeve 16 is provided with a thread sleeve gear 19. The thread sleeve 16 and the thread sleeve gear 19 form a spiral pair connection, and the thread sleeve 16 and the trapezoidal thread screw 11 form a rotary pair connection. The side of the outer wall panel 23 close to the digital indicator 14 is provided with an intermediate gear 18, and the driving gear 17 and the thread sleeve gear 19 are both meshed with the intermediate gear 18. The intermediate gear 18 is meshed with the driving gear 17 and the threaded sleeve gear 19. When the driving gear 17 rotates, the intermediate gear 18 can be used to transmit motion to rotate the threaded sleeve gear 19. The end of the inclination adjustment shaft 20 close to one of the driving gears 17 is installed inside the digital indicator 14. One end of the inclination adjustment shaft 20 is installed inside the digital indicator 14. The rotation of the inclination adjustment shaft 20 can be controlled when the hand wheel is turned. The left and right sides of the upper guide rail seat 2 are both installed with external mounting blocks 13. The external mounting blocks 13 are fixedly connected to the upper guide rail seat 2 and connected to the threaded sleeve 16 to form a moving pair. The upper guide rail seat 2 is connected to the inclination adjustment shaft 20, the threaded sleeve gear 19, and the intermediate gear 18 to form a rotary pair.

[0039] Working principle: When adjusting the opening, the hand wheel does not move, and the servo motor 24 is started. The servo motor 24 drives the active sprocket 4 to rotate. The active sprocket 4 drives the double-row sprocket 7 to rotate through the short chain 6. When the double-row sprocket 7 rotates, it drives the driven sprocket 9 to rotate through the long chain 8. At this time, the double-row sprocket 7 and the driven sprocket 9 simultaneously drive the two trapezoidal threaded screws 11 to rotate. The rotation of the two trapezoidal threaded screws 11 drives the nut sliders 12 thereon to move in the same direction, and finally drives the translational movement of the inner gauge 22 and the outer gauge 21. By changing the direction and angular displacement of the servo motor 24, the size of the spacing opening between the inner gauge 22 and the outer gauge 21 can be controlled;

[0040] When adjusting the inclination, the servo motor 24 is powered off, a hand wheel is installed at one end of the digital indicator 14, the adjustable handle 15 is loosened, and the hand wheel is turned to drive the inclination adjustment shaft 20 to rotate. The rotation of the inclination adjustment shaft 20 drives the driving gear 17 to rotate, and the motion is transmitted through the intermediate gear 18. The threaded sleeve gear 19 has the same direction as the driving gear 17, and then the threaded sleeve 16 is connected to the spiral pair of the threaded sleeve gear 19. When the threaded sleeve gear 19 rotates, the threaded sleeve 16 performs a translational motion. Since the threaded sleeve 16 and the trapezoidal thread lead screw 11 form a rotary pair connection, the trapezoidal thread lead screw 11 is driven to perform a left and right translational motion together. Since the trapezoidal thread lead screw 11 and the nut slider 12 are equivalent to a fixed connection, the nut slider 12 is driven to perform a left and right translational motion. At this time, two of the nut sliders 12 are stationary, and the other two nut sliders 12 move and have relative motion. The inner gauge 22 and the outer gauge 21 will be tilted to one side and the inner gauge 22 is parallel to the outer gauge 21, thereby completing the inclination adjustment.

[0041] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
