Description

Technical Field

[0001] This utility model relates to the field of collating machine pressing technology, specifically a collating machine pressing structure to prevent bookmarks from tilting. Background Technology

[0002] The collating machine is a core piece of equipment in the printing and binding production line. Its main function is to automatically collect and stack printed single sheets of paper or folded book notes in page order to form a complete book block, which is used to prepare for subsequent binding. It accurately stacks scattered sheets of paper or book notes in the page order of the book to ensure that the content of the book is coherent and error-free after it is finished. The collating machine is an indispensable key piece of equipment in the modern printing industry.

[0003] In the collating process, skewed bookplates are a common and troublesome problem. They not only affect the aesthetics of the bound document but also negatively impact the reading experience. When bookplates are skewed, the edges of the document may be uneven, making the entire document appear rough and unprofessional. For documents that need to be displayed or submitted externally, this may leave a bad impression on the recipient and even affect the document's acceptance. To ensure the neatness of the document and ease of reading, solving the problem of skewed bookplates during the collating process is crucial. Utility Model Content

[0004] The purpose of this invention is to provide a collating machine pressing structure that prevents bookmarks from tilting, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a collating machine pressing structure for preventing bookmark skewing, comprising a base, a back plate mounted on the upper surface of the base, a fixing plate mounted on the upper surface of the back plate, a controller mounted on the left side of the back plate, a stepper motor mounted on the upper surface of the fixing plate, a support rod mounted on the output end of the stepper motor, an NPN photoelectric switch mounted on the upper surface of the support rod, an electric telescopic rod A mounted on the bottom surface of the support rod, a fixing block mounted on the output end of the electric telescopic rod A, rotary motors mounted on both sides of the fixing block, and a brush mounted on the output end of each rotary motor.

[0006] The base has support plates installed on both sides, and each support plate has two sliding grooves on its outer surface.

[0007] Both sliding grooves have side plates slidably installed inside, and the outer surface of the support plate is equipped with baffles.

[0008] The outer surface of the baffle is equipped with a hydraulic rod, and the output end of the hydraulic rod is connected to the outer surface of the side plate.

[0009] The base has a fixed column on its right side and an electric telescopic rod B on its left side.

[0010] Among them, the output end of the electric telescopic rod B is equipped with an L-shaped bracket, the bottom surface of the L-shaped bracket is equipped with the electric telescopic rod C, and the output end of the electric telescopic rod C is equipped with a support block.

[0011] The support block has two vacuum pumps installed on its bottom surface, and the output end of each vacuum pump is connected to a suction cup.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: The brush in this utility model can reduce the skew phenomenon. When the brush rotates, it generates a guiding force, which pushes the book block smoothly towards the back plate. Under the coordinated limiting action of the back plate and the side plate, precise alignment is achieved. When the L-shaped bracket moves towards the back plate, the movement trajectory of the L-shaped bracket will trigger the detection area of ​​the NPN photoelectric switch. At this time, the NPN photoelectric switch transmits the signal to the controller, which controls the stepper motor to start the rotation mechanism, so that the L-shaped bracket and the L-shaped bracket connecting assembly deflect as a whole, effectively avoiding the key working parts of the suction cup. After the avoidance action is completed, as the L-shaped bracket resets and moves away from the back plate, the stepper motor drives the structure to return to the initial position. At the same time, the electric telescopic rod performs a pressing action and rotates the brush to ensure the stable positioning of the book block. This series of linkage actions realizes the organic combination of dynamic obstacle avoidance and precise positioning. Attached Figure Description

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] Please see Figure 1-4 This utility model provides a technical solution: a collating machine pressing structure to prevent bookmark skewing, including a base 1, a back plate 2 mounted on the upper surface of the base 1, a fixing plate 3 mounted on the upper surface of the back plate 2, a controller 11 mounted on the left side of the back plate 2, a stepper motor 4 mounted on the upper surface of the fixing plate 3, a support rod 5 mounted on the output end of the stepper motor 4, an NPN photoelectric switch 7 mounted on the upper surface of the support rod 5, an electric telescopic rod A6 mounted on the bottom surface of the support rod 5, and a fixing block mounted on the output end of the electric telescopic rod A6. 8. Rotary motors 9 are installed on both sides of the fixing block 8. Each rotary motor 9 has a brush 10 installed at its output end. When the L-shaped bracket 18 moves toward the back plate 2, the NPN photoelectric switch 7 detects the bracket position signal. At this time, the NPN photoelectric switch 7 transmits the signal to the controller 11, triggering the stepper motor 4 to rotate. After completing the avoidance, the suction cup 22 uses the vacuum pump 21 to drop the book into the designated area. Then, the stepper motor 4 drives the structure to reset, and the electric telescopic rod A6 presses down and rotates the brush 10 to ensure that the book is accurately aligned.

[0017] The base 1 has support plates 12 installed on both sides. Each support plate 12 has two sliding grooves 13 on its outer surface. The sliding grooves 13 enable the side plate 23 to move smoothly and linearly within the grooves. The sliding grooves 13 can reduce friction and ensure that the side plate 23 can be smoothly adjusted in position under the drive of the hydraulic rod 14. The guide structure design of the sliding grooves 13 effectively restricts the movement trajectory of the side plate 23 and prevents it from deviating or shaking during movement, thereby ensuring the accuracy of the book's positioning.

[0018] The two sliding grooves 13 each have a side plate 23 slidably installed inside, and a baffle 15 is installed on the outer surface of the support plate 12. The baffle 15 can fix the hydraulic rod 14. Its structural design can effectively withstand the axial and radial loads generated by the hydraulic rod 14 during operation, ensuring the stability of the hydraulic transmission system.

[0019] Hydraulic rods 14 are installed on the outer surface of baffle 15. The output end of hydraulic rods 14 is connected to the outer surface of side plate 23. Hydraulic rods 14 can fix side plate 23 to prevent tilting and ensure the stability and accuracy of the entire collating system. The adaptive adjustment and stable support of hydraulic rods 14 also help improve the overall performance and working efficiency of collating machine.

[0020] The base 1 has a fixed column 16 installed on its right side and an electric telescopic rod B17 installed on its left side. The electric telescopic rod B17 drives the L-shaped bracket 18 to perform precise reciprocating linear motion in the horizontal direction through its precision electric push rod mechanism, ensuring that the bracket assembly can be accurately positioned to the preset working position.

[0021] Among them, the output end of the electric telescopic rod B17 is equipped with an L-shaped bracket 18, the bottom surface of the L-shaped bracket 18 is equipped with an electric telescopic rod C19, and the output end of the electric telescopic rod C19 is equipped with a support block 20. The suction cup 22 and the surface of the book are formed with the best negative pressure adsorption effect by adjusting the pressing depth, making it easier to adsorb the book.

[0022] The support block 20 has two vacuum pumps 21 mounted on its bottom surface. The output end of each vacuum pump 21 is connected to a suction cup 22. The vacuum pump 21 is an important component of the collating machine. By generating a stable negative pressure, it enables the suction cup 22 to form a reliable adsorption force with the surface of the book. The specially designed suction cup 22 structure can adapt to different paper surfaces. Whether it is smooth paper or slightly rough paper, the suction cup can provide uniform adsorption force to ensure no leakage adsorption. This greatly improves the adaptability of the collating machine to different types of paper, making it easier and faster for operators to perform collating operations.

[0023] Working principle: The sliding grooves 13 on the support plates 12 installed on both sides of the base 1 allow the side plate 23 to move laterally within the sliding grooves 13. The baffle 15 is fixed on the outer surface of the support plate 12. The hydraulic rod 14 is installed on the baffle 15. The output end of the hydraulic rod 14 is connected to the side plate 23. The position of the side plate 23 is adjusted by driving the hydraulic rod 14 to adapt to the limiting requirements of different sizes of book blocks. The right side of the base 1 is equipped with a fixed column 16, and the left side is connected to an electric telescopic rod B17, which is used to control the horizontal movement of the L-shaped bracket 18. When the electric telescopic rod B17 extends or retracts, it drives the L-shaped bracket 18 to reciprocate, achieving the positioning or avoidance of the booklet. The electric telescopic rod C19 is installed at the bottom of the L-shaped bracket 18. Two vacuum pumps 21 are set below the support block 20, which are connected to the suction cup 22. When the electric telescopic rod C19 is pressed down, the vacuum pump 21 makes the suction cup 22 contact the booklet and fix it, ensuring that the booklet remains stable during the correction process. When the L-shaped bracket 18 moves towards the back plate 2, the NPN photoelectric switch 7 detects the position signal of the bracket. At this time, the NPN photoelectric switch 7 transmits the signal to the controller 11, triggering the stepper motor 4 to rotate, causing the support rod 5 and connecting components to deflect, avoiding collision with the suction cup 22. After the avoidance is completed, the suction cup 22 drops the booklet into the designated area. Then the stepper motor 4 drives the structure to reset, and the electric telescopic rod A6 presses down and rotates the brush 10 to ensure that the booklet is accurately aligned.
