A waste collection mechanism for a combined printing press

Abstract

This utility model belongs to the field of waste collection technology for printing presses, specifically a waste collection mechanism for a combined printing press, including: a first frame, a second frame, and a third frame. A second drive motor is installed on one side of the third frame, and a bidirectional screw is fixedly connected to the output end of the second drive motor. One end of the bidirectional screw is rotatably connected inside the third frame. As the hollow cylinder moves outward towards the discharge roller under the pushing force of the second drive motor, the bidirectional screw, and the pusher frame, the resulting friction causes the balls to rotate along the surface of the oil-retaining cotton. The surface of the balls is coated with lubricating oil, making the rotation of the balls and the detachment from the discharge roller smoother. Subsequently, through two sets of relatively rotating third drive motors, two sets of crushing rollers rotate relative to each other, crushing the hollow cylinder that falls into the waste bin. This reduces the secondary handling of waste during the waste collection process, thereby improving waste processing efficiency.

Description

Technical Field

[0001] This utility model belongs to the field of printing press waste collection technology, specifically a waste collection mechanism for a combined printing press. Background Technology

[0002] A combination printing press combines multiple printing devices based on different principles to form an integrated production line, enabling online production of multi-color printing, post-printing processing, and other processes. In order to recycle the hollow tubes of printed paper during the use of the printing press and reduce the downtime of the combination printing press, a waste collection mechanism for the combination printing press is needed.

[0003] A Chinese patent with authorization announcement number CN221680236U discloses a waste collection mechanism for a combination printing press. It uses a double-headed cylinder to push two sets of moving rings through a connecting rod to push the take-up cylinders located at both ends of the take-up roller out of the take-up roller, so that the unused take-up cylinders move to the end of the take-up roller and the cut waste is wound onto the new take-up cylinders. There is no need to stop the machine to replace the take-up cylinders, and the printing efficiency of the printing press is not reduced.

[0004] However, the above solution still has some problems. After the hollow cylinder is removed from the feeding roller, it needs to be processed again for secondary waste disposal, which reduces the efficiency of waste disposal. Therefore, a waste collection mechanism for a combined printing press is proposed to address the above problems. Utility Model Content

[0005] To overcome the shortcomings of existing technologies and address the problems of existing equipment, this utility model proposes a waste collection mechanism for a combined printing press.

[0006] The technical solution adopted by this utility model to solve its technical problem is a waste collection mechanism for a combined printing press, including: a first frame, a second frame, and a third frame. A second drive motor is installed on one side of the third frame, and a bidirectional screw is fixedly connected to the output end of the second drive motor. One end of the bidirectional screw is rotatably connected to the inside of the third frame. A pusher frame is threadedly connected to the bidirectional screw, and the pusher frame has internal threads. A support rod is fixedly connected to one side of the third frame, and a feeding roller is fixedly connected to the support rod. A ball bearing is rotatably connected to the feeding roller. The machine is equipped with an oil storage cotton inside. A connecting frame is fixedly connected to one side of the pusher frame, and an auxiliary frame is fixedly connected to one end of the connecting frame. A limiting frame is fixedly connected to the third frame. The limiting frame is located on the outer side between the doctor blade roller and the take-up roller. Since the auxiliary frame and the pusher frame are located at the two ends of the feed roller, when feeding printing paper, one end of the hollow cylinder is fitted onto one end of the feed roller. The second drive motor runs, driving the bidirectional screw to rotate, which in turn drives the pusher frame, the connecting frame, and the auxiliary frame to move. This allows for auxiliary processing when feeding printing paper, making the feeding of the combined printing machine more convenient.

[0007] Preferably, a waste bin is installed on one side of the third frame, and a door is hinged to one side of the waste bin. An electric telescopic rod is installed on the inner wall of the waste bin, and a pusher plate is installed on the telescopic end of the electric telescopic rod. The waste bin and the door cooperate to collect and store the crushed hollow cylinder waste.

[0008] Preferably, two sets of third drive motors are installed on one side of the waste bin. The output ends of the two sets of third drive motors are fixedly connected to crushing rollers. One end of the crushing rollers is rotatably connected to the inside of the waste bin. The two sets of third drive motors rotate in opposite directions, which can drive the two sets of crushing rollers to rotate relative to each other, thereby crushing the hollow cylinder that falls into the waste bin.

[0009] Preferably, a support roller, a printing roller, a doctor blade roller, and a take-up roller are rotatably connected to the first frame, the second frame, and the third frame. A first drive motor is provided at one end of each of the support roller, the printing roller, the doctor blade roller, and the take-up roller. The first drive motor is installed on one side of the first frame, the second frame, and the third frame. A limit bolt is threaded to one end of the take-up roller. The limit bolt cooperates with one side of the frame to limit the winding of the printing paper.

[0010] Preferably, an elastic rubber pad and an ink feed roller are fixedly connected to one side of the printing roller. A spiral plate is provided between the ink feed roller and the elastic rubber pad. A material transfer pipe is provided on one side of the first frame, the second frame, and the third frame, and the material transfer pipe is opposite to the open end of the ink feed roller. A suction pump is provided on the material transfer pipe. The suction pump is installed on one side of the first frame, the second frame, and the third frame. The material transfer pipe is connected to an external pipe for printing ink transmission. The suction pump is started by an external controller, and the printing ink can be drawn into the interior of the ink feed roller through the material transfer pipe.

[0011] Preferably, the waste collection mechanism is externally connected to a controller. The external controller is used to control the start and stop of the first frame, the second frame, the third frame, the first drive motor, the second drive motor, the electric telescopic rod, the material pump, and the third drive motor. By controlling the first drive motor, the second drive motor, the material pump, and the third drive motor through the external controller, the ease of use of the mechanism is improved.

[0012] The advantages of this invention are as follows: As the hollow cylinder moves outward from the discharge roller under the thrust of the second drive motor, the bidirectional screw, and the pusher, the resulting friction causes the balls to rotate along the surface of the oil-storage cotton. The balls are coated with lubricating oil, making the rotation of the balls and the detachment from the discharge roller smoother. Subsequently, two sets of relatively rotating third drive motors drive two sets of crushing rollers to rotate relative to each other, crushing the hollow cylinder that falls into the waste bin. This reduces the secondary handling of waste during the waste collection and processing process, thereby improving the waste processing efficiency.

[0013] This invention allows the printing ink to flow along the spiral plate, with the ink evenly distributed circumferentially along the spiral groove, eliminating end effects. Furthermore, the spiral plate forces the ink to move along the spiral path, avoiding the axial unevenness of traditional straight-through ink supply. It also matches the rotating doctor blade roller, thereby improving the uniformity of ink distribution on the elastic rubber pad and thus improving printing quality. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments.

[0022] Please see Figure 1-5 As shown, a waste collection mechanism for a combined printing press includes: a first frame 1, a second frame 2, and a third frame 3. A second drive motor 10 is mounted on one side of the third frame 3. A bidirectional screw 11 is fixedly connected to the output end of the second drive motor 10. One end of the bidirectional screw 11 is rotatably connected to the inside of the third frame 3. A pusher frame 12 is threadedly connected to the bidirectional screw 11. The pusher frame 12 has an internal thread. A support rod 13 is fixedly connected to one side of the third frame 3. A feeding roller 14 is fixedly connected to the support rod 13. A ball bearing 15 is rotatably connected to the feeding roller 14. An oil storage cotton 16 is disposed inside the feeding roller 14. The pusher frame 12... A connecting frame 17 is fixedly connected to one side of the machine, and an auxiliary frame 18 is fixedly connected to one end of the connecting frame 17. A limiting frame 19 is fixedly connected to the third frame 3. The limiting frame 19 is located on the outer side between the doctor blade roller 6 and the take-up roller 7. A waste bin 20 is installed on one side of the third frame 3. A door 21 is hinged to one side of the waste bin 20. An electric telescopic rod 22 is installed on the inner wall of the waste bin 20. A pusher plate 23 is installed at the telescopic end of the electric telescopic rod 22. Two sets of third drive motors 24 are installed on one side of the waste bin 20. A crushing roller 25 is fixedly connected to the output end of each of the two sets of third drive motors 24. One end of the crushing roller 25 is rotatably connected to the inside of the waste bin 20.

[0023] To recover waste paper from hollow tubes during printing press operation, reduce downtime of the combined printing press, and thus improve its efficiency, a waste collection mechanism for the combined printing press is needed. In actual use, the pusher frame 12 is located at the end of the feeding roller 14 away from the support rod 13. When feeding paper, one end of the hollow tube is placed over the feeding roller 14. The second drive motor 10 is started by an external controller, which drives the bidirectional screw 11 to rotate, thereby driving the pusher frame 12 and the connecting... The frame 17 and auxiliary frame 18 move toward the support rod 13, allowing the auxiliary frame 18 to assist in feeding the printing paper. During the sliding of the hollow cylinder, the friction generated drives the ball bearings 15 to rotate along the surface of the oil-retaining cotton 16. The ball bearings 15, coated with lubricating oil, rotate more smoothly, thus improving the smoothness of the hollow cylinder's movement along the feeding roller 14. This makes feeding the combined printing press more convenient. Subsequently, the pusher frame 12, connecting frame 17, and auxiliary frame 18 work together to fix the printing paper. On the feeding roller 14, the printing paper passes through the limiting frame 19, further restricting the movement range of the printing paper. Then, the printing paper passes through the combined printing press and connects to the receiving roller 7. When the printing paper on the hollow cylinder is used up, the second drive motor 10 is started via an external controller, driving the bidirectional screw 11 to rotate. Because the internal thread of the pusher frame 12 matches the thread on the bidirectional screw 11, the rotation of the bidirectional screw 11 drives the pusher frame 12 to move again towards the outside of the feeding roller 14, thus pushing the hollow cylinder off the feeding roller 14. The hollow cylinder falls into the waste bin 20. Then, the external controller starts two sets of third drive motors 24, which rotate in opposite directions. This drives the two sets of crushing rollers 25 to rotate relative to each other, thereby crushing the hollow cylinder that has fallen into the waste bin 20. When there are a lot of debris inside the waste bin 20, the external controller starts the electric telescopic rod 22. The electric telescopic rod 22 extends outward and drives the pusher plate 23 to move, which pushes the crushed hollow cylinder outward and cleans the inside of the waste bin 20.

[0024] Please see Figure 1-5As shown, a support roller 4, a printing roller 5, a doctor blade roller 6, and a take-up roller 7 are rotatably connected to the first frame 1, the second frame 2, and the third frame 3. A first drive motor 8 is installed at one end of each of the support roller 4, the printing roller 5, the doctor blade roller 6, and the take-up roller 7. The first drive motor 8 is mounted on one side of each of the first frame 1, the second frame 2, and the third frame 3. A limit bolt 9 is threaded to one end of the take-up roller 7. An elastic rubber pad 26 and an ink feed roller 27 are fixedly connected to one side of the printing roller 5. A spiral plate 2 is provided between the ink feed roller 27 and the elastic rubber pad 26. 8. A material transfer pipe 29 is provided on one side of the first frame 1, the second frame 2 and the third frame 3, and the material transfer pipe 29 is opposite to the open end of the ink feed roller 27. A material pump 30 is provided on the material transfer pipe 29. The material pump 30 is installed on one side of the first frame 1, the second frame 2 and the third frame 3. The waste collection mechanism is externally connected to a controller. The external controller is used to control the start and stop of the first frame 1, the second frame 2, the third frame 3, the first drive motor 8, the second drive motor 10, the electric telescopic rod 22, the material pump 30 and the third drive motor 24.

[0025] The first frame 1, second frame 2, third frame 3, support roller 4, printing roller 5, doctor blade roller 6, and take-up roller 7 are the main structural components of the RXASY-1000A combined printing press. The RXASY-1000A is also equipped with an electric heating drying device. After the hollow cylinder containing printing paper is placed on the feed roller 14, one end of the printing paper is pulled to pass through the limit frame 19. The other end of the printing paper then passes between the three sets of printing rollers 5 and the support roller 4, and is subsequently fixed to the take-up roller 7. The feed pipe 29 is connected to the external pipeline for printing ink transmission. The pump 30 is started via the external controller, drawing printing ink through the feed pipe 29 into the interior of the inking roller 27. The printing ink then flows through the inking roller... The ink flows through the holes on roller 27 into the inner wall of elastic rubber pad 26, and the printing ink flows along the spiral plate 28. The ink is evenly distributed circumferentially along the spiral groove, eliminating the end effect. The spiral plate 28 forces the ink to move along the spiral path, which can avoid the axial unevenness of traditional straight-through ink supply. It also matches the rotating doctor blade roller 6, thereby improving the uniformity of ink reception on the elastic rubber pad 26 and thus improving the printing quality. Then, the first drive motor 8 is started by the external controller, which drives the support roller 4, doctor blade roller 6, printing roller 5 and take-up roller 7 to rotate, which can pull the printing paper so that the printed and dried printing paper is rolled up on the take-up roller 7. Then, the limit bolt 9 is unscrewed, and the printing roll can be removed from the take-up roller 7 for collection.

[0026] Working principle: Before loading the hollow cylinder containing printing paper, the pusher frame 12 is positioned at the end of the feeding roller 14 furthest from the support rod 13. When loading the printing paper, one end of the hollow cylinder is fitted onto one end of the feeding roller 14. The second drive motor 10 is started via an external controller, driving the bidirectional screw 11 to rotate. This, in turn, moves the pusher frame 12, connecting frame 17, and auxiliary frame 18 towards the support rod 13. During printing paper loading, the auxiliary frame 18 assists in the loading process. Furthermore, the friction generated during the sliding of the hollow cylinder causes the ball bearings 15 to rotate along the surface of the oil-retaining cotton 16. The surface of the ball bearings 15 is coated with lubricant. The lubricating oil makes the ball bearing 15 rotate more smoothly, thereby improving the smoothness of the hollow cylinder moving along the feed roller 14, making the feeding of the combination printing press more convenient. Then, through the cooperation of the pusher frame 12, connecting frame 17 and auxiliary frame 18, the printing paper is fixed on the feed roller 14. Pulling one end of the printing paper so that it passes through the limit frame 19, the other end of the printing paper passes between the three sets of printing rollers 5 and the support roller 4, and is then fixed on the take-up roller 7. The feed pipe 29 is connected to the external pipe for printing ink transmission. The pump 30 is started through the external controller to draw the printing ink into the interior of the inking roller 27 through the feed pipe 29. Furthermore, the printing ink flows along the spiral plate 28, avoiding the axial unevenness of traditional straight-through ink supply, and matches the rotating doctor blade roller 6, thereby improving the uniformity of ink distribution on the elastic rubber pad 26 and thus improving printing quality. Subsequently, the first drive motor 8 is started by the external controller, driving the doctor blade roller 6, support roller 4, printing roller 5, and take-up roller 7 to rotate, thus pulling the printing paper. After printing, the second drive motor 10 is started by the external controller, driving the bidirectional screw 11 to rotate. Because the internal thread of the pusher frame 12 matches the thread on the bidirectional screw 11, the rotation of the bidirectional screw 11 can drive the paper to rotate. The pusher 12 moves outward from the discharge roller 14 again, pushing the hollow cylinder off the discharge roller 14 and causing it to fall into the waste bin 20. The external controller starts two sets of third drive motors 24, which rotate in opposite directions, driving the two sets of crushing rollers 25 to rotate relative to each other, thereby crushing the hollow cylinder that has fallen into the waste bin 20. When there are a lot of debris inside the waste bin 20, the external controller starts the electric telescopic rod 22, which extends outward and drives the pusher plate 23 to move, pushing the crushed hollow cylinder outward and cleaning the inside of the waste bin 20.
