Description

Technical Field

[0001] This utility model relates to the field of printing equipment technology, and in particular to an automatic layering device for printing presses. Background Technology

[0002] In the printing industry's production process, the prerequisite for a printing press to perform printing operations on paper is to achieve a stable and orderly supply of individual sheets. However, in actual production scenarios, the paper to be printed is usually stored and transported in stacks of hundreds or thousands of sheets. This makes separating the stacked paper into individual sheets a key process in the pre-printing treatment stage.

[0003] When using the above technology, the following technical problems were found in the existing technology: At present, in the paper separation process, it mainly relies on manual sorting of sheets one by one or simple mechanical devices for layering operations;

[0004] However, traditional paper separation methods generally suffer from the technical problem of paper sticking, which causes multiple sheets of paper to enter the printing unit at the same time. This phenomenon not only significantly reduces the quality of printed materials and work efficiency, but may also cause serious paper jams and even permanent damage to printing machinery. To address this, we have designed an automatic paper separation device for printing presses to provide an alternative technical solution to the above-mentioned technical problems. Utility Model Content

[0005] The purpose of this invention is to provide an automatic layering device for printing presses to solve the problems mentioned in the background art.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0007] An automatic layering device for printing presses includes a U-shaped frame. A placement plate is slidably connected to the bottom of the inner side of the U-shaped frame. U-shaped slide rails are provided at the top of both sides of the U-shaped frame. Guide slide rods are slidably connected to the inner side of the U-shaped slide rails. Support slide rods are fixed to the ends of the two guide slide rods that are close to each other. A separation pad is fixed to the bottom end of the support slide rod. A reciprocating swing mechanism for driving the separation pad to move is provided at the top of the inner side of the U-shaped frame.

[0008] The reciprocating swing mechanism includes an A servo motor, a drive rod, and a slide groove. The top of both sides of the U-shaped frame are equipped with an A servo motor. The output end of the A servo motor passes through the U-shaped frame and is fixed to the drive rod. The bottom of the drive rod is provided with a slide groove, and the inner side of the slide groove is slidably connected to the guide slide rod.

[0009] The top of the U-shaped frame is fixed with U-shaped guides on both sides. The outer side of the U-shaped guides is slidably connected to a limit slider, and the inside of the limit slider is slidably connected to a support slide rod.

[0010] The bottom end of the U-shaped frame is equipped with a lifting mechanism for moving the placement plate and paper upward. The lifting mechanism includes a drive shaft, a drive rod, a linkage rod, a main bevel gear, a driven bevel gear, and a B servo motor. The bottom end of the U-shaped frame is rotatably connected to the drive rod, and both sides of the drive rod are fixed with drive shafts. One end of the drive shaft is rotatably connected to the linkage rod, and the end of the linkage rod away from the drive shaft is rotatably connected to the placement plate.

[0011] The bottom end of the U-shaped frame is equipped with a B servo motor, the output end of which is fixed with a main bevel gear. A driven bevel gear is meshed with one side of the main bevel gear, and the interior of the driven bevel gear is fixed to the transmission rod.

[0012] The U-shaped frame is equipped with separation belts at both ends, a conveyor plate is fixed at the bottom of the U-shaped frame, and a conveyor belt is installed on the inner side of the conveyor plate.

[0013] It is clear without a doubt that the technical solution described above in this application can solve the technical problem that this application aims to address.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: This utility model drives the drive rod to rotate by starting the A servo motor. The drive rod drives the guide slide rod to move through the internal slide groove. The guide slide rod then drives the support slide rod to move along the U-shaped slide rail in a U-shaped trajectory, thereby causing the separation pad at the bottom of the support slide rod to move synchronously. The limiting slider plays a limiting role on the support slide rod, ensuring that the separation pad is in stable contact with the top layer of paper, so that the separation pad can separate and print the paper one by one.

[0015] The B servo motor drives the transmission rod to rotate via the main bevel gear and the driven bevel gear. The transmission shafts on both sides of the transmission rod rotate accordingly and apply pressure to the linkage rod. The linkage rod pushes the placement plate upward, so that the paper on the placement plate always keeps in contact with the separation pad, ensuring the quality and efficiency of paper delivery by the separation pad.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0024] Please see Figure 1-5 This utility model provides a technical solution: an automatic layering device for printing on a printing machine, including a U-shaped frame 1, a placement plate 8 slidably connected to the bottom of the inner side of the U-shaped frame 1, U-shaped slide rails 9 being provided at the top of both sides of the U-shaped frame 1, guide slide rods 18 slidably connected to the inner side of the U-shaped slide rails 9, support slide rods 11 being fixed at the ends of the two guide slide rods 18 that are close to each other, a separation pad 19 being fixed at the bottom of the support slide rod 11, and a reciprocating swing mechanism for driving the separation pad 19 to move is provided at the top of the inner side of the U-shaped frame 1.

[0025] When in use, a large amount of paper is placed on the placement plate 8, and the reciprocating swing mechanism drives the separation pad 19 to separate the stacked paper one by one, effectively separating the paper that is stuck together, so as to effectively transport the single layer of paper to the printing press for printing, thereby promoting the printing quality of paper being transported one by one.

[0026] The reciprocating swing mechanism includes an A servo motor 10, a drive rod 17, and a slide groove. The top of both sides of the U-shaped frame 1 are equipped with the A servo motor 10. The output end of the A servo motor 10 passes through the U-shaped frame 1 and is fixed with the drive rod 17. The bottom of the drive rod 17 is provided with a slide groove, and the inner side of the slide groove is slidably connected to the guide slide rod 18.

[0027] Specifically, by starting servo motor A 10, the drive rod 17 is rotated, and the drive rod 17 drives the guide slide rod 18 to move along the inner side of the slide groove. The guide slide rod 18 drives the support slide rod 11 to move along the U-shaped slide rail 9 in a U-shaped trajectory. This allows servo motor A 10 to drive the drive rod 17, support slide rod 11 and separation pad 19 to press and convey the top layer of paper one by one along the U-shaped slide rail 9. Thus, the separation pad 19 reciprocates to convey the top layer of paper to both ends of the U-shaped frame 1 for separation.

[0028] Both sides of the top of the U-shaped frame 1 are fixed with U-shaped guide frames 3. The outer side of the U-shaped guide frame 3 is slidably connected to the limiting slider 6. The inside of the limiting slider 6 is slidably connected to the support slide rod 11. The support slide rod 11 drives the limiting slider 6 to move synchronously back and forth along the U-shaped guide frame 3. The limiting slider 6 effectively limits the support slide rod 11 to prevent the separation pad 19 from tilting and to avoid uneven adhesion between the bottom of the separation pad 19 and the paper.

[0029] The bottom end of the U-shaped frame 1 is provided with a lifting mechanism for moving the placement plate 8 and the paper upward. The lifting mechanism includes a drive shaft 7, a drive rod 13, a linkage rod 14, a main bevel gear 15, a driven bevel gear 16, and a B servo motor 12. The bottom end of the U-shaped frame 1 is rotatably connected to the drive rod 13. The drive shaft 7 is fixed on both sides of the drive rod 13. One end of the drive shaft 7 is rotatably connected to the linkage rod 14. The end of the linkage rod 14 away from the drive shaft 7 is rotatably connected to the placement plate 8. The bottom end of the U-shaped frame 1 is equipped with a B servo motor 12. The output end of the B servo motor 12 is fixed to the main bevel gear 15. One side of the main bevel gear 15 is meshed with the driven bevel gear 16. The interior of the driven bevel gear 16 is fixed to the drive rod 13.

[0030] Specifically, by starting the B servo motor 12, the main bevel gear 15, the driven bevel gear 16 and the transmission rod 13 are rotated. The transmission rod 13 drives the transmission shaft 7 to apply pressure to the linkage rod 14, and the linkage rod 14 squeezes the placement plate 8. At this time, the placement plate 8 drives a large amount of paper to move upward, ensuring that the top layer of paper is in contact with the bottom of the separation pad 19, so that the bottom of the separation pad 19 can reciprocate to transport the top layer of paper. The lifting mechanism drives the placement plate 8 to effectively keep the paper in contact with the separation pad 19.

[0031] Both ends of the U-shaped frame 1 are equipped with separation belts 5, and the bottom end of the U-shaped frame 1 is fixed with a conveyor plate 2. The inner side of the conveyor plate 2 is equipped with a conveyor belt 4. Through the cooperation between the lifting mechanism and the reciprocating swing mechanism, the separation pad 19 can transport the stacked paper one by one to the separation belt 5. Then the separation belt 5 drives the single layer of paper to be transported to the conveyor belt 4, so that the conveyor belt 4 can transport them to the printing press.

[0032] The usage process of the automatic layering device for printing presses provided by this utility model is as follows:

[0033] First, a large number of papers to be printed are placed on the placement plate 8. Then, the A servo motor 10 is started to drive the drive rod 17 to rotate. The drive rod 17 drives the guide slide rod 18 to move through the internal slide groove. The guide slide rod 18 then drives the support slide rod 11 to move along the U-shaped slide rail 9 in a U-shaped trajectory, thereby causing the separation pad 19 at the bottom of the support slide rod 11 to move synchronously.

[0034] During this process, the support slide bar 11 will also drive the limiting slider 6 to reciprocate synchronously along the U-shaped guide frame 3. The limiting slider 6 plays a limiting role on the support slide bar 11, ensuring that the separation pad 19 is in stable contact with the top layer of paper.

[0035] At the same time, the B servo motor 12 drives the transmission rod 13 to rotate through the main bevel gear 15 and the secondary bevel gear 16. The transmission shafts 7 on both sides of the transmission rod 13 rotate accordingly and apply pressure to the linkage rod 14. The linkage rod 14 pushes the placement plate 8 to move upward, so that the paper on the placement plate 8 always stays in contact with the separation pad 19.

[0036] The separation pad 19 separates the stacked papers one by one in the reciprocating motion, separating the papers that are stuck together. The separated single-layer paper is transported to the separation belts 5 at both ends of the U-shaped frame 1, and then transported by the separation belts 5 to the conveyor belt 4. Finally, the conveyor belt 4 collects and sends the paper into the printing press for printing.

[0037] Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.
