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

[0002] A carton printing machine is a printing device that can print the required text, patterns and other information onto the surface of a carton. It generally includes processes such as plate mounting, inking, printing, and paper feeding. Carton printing generally includes single printing, printing with slotting / die-cutting, printing with slotting / die-cutting, gluing, and integrated production lines.

[0016] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0017] Reference Figure 1-4 This utility model discloses an automatic feeding and correction device for a printing machine, comprising a housing 1, an opening 22 on the left side of the housing 1, a door 23 hinged within the opening 22, and casters 24 fixedly connected to the bottom of the housing 1. The casters 24 are self-locking casters, providing high stability and flexibility. Whether moving linearly or turning within the workshop, it can be easily achieved. Furthermore, once positioning is complete, the self-locking function ensures that the equipment will not shift due to external forces, guaranteeing operational reliability. A mounting plate 2 is fixedly connected to the right side of the box body 1. Slide grooves 18 are provided on both the front and rear sides of the box body 1, and a lifting plate 19 is slidably connected inside. Guide blocks 21 are fixedly connected to both the front and rear sides of the lifting plate 19. The guide blocks 21 are located within the slide grooves 18 and slidably connected to the slide grooves 18. A compression spring 20 is fixedly connected to the lower side of the lifting plate 19 and the bottom of the box body 1. When the carton is placed on the lifting plate 19, the compression spring 20 is compressed, generating appropriate elastic force. On the one hand, it provides flexible support for the carton, avoiding damage to the carton surface due to rigid contact; on the other hand, when the weight of the carton changes, the lifting plate 19 can automatically adjust its height, always maintaining good contact with the carton and ensuring the stability of the conveying process.

[0018] The mounting plate 2 is L-shaped, making the layout of each component more compact and reasonable. It has a groove 13 on the upper side, and a second rubber roller 14 is rotatably connected in the groove 13. A second servo motor 15 is fixedly connected to the front side of the mounting plate 2. The output end of the second servo motor 15 is fixedly connected to the second rubber roller 14. An auxiliary roller 12 is provided on the mounting plate 2 above the second rubber roller 14. A second limiting groove 9 is provided on the mounting plate 2 at both ends of the auxiliary roller 12. A second slider 10 is slidably connected in the second limiting groove 9. The two ends of the auxiliary roller 12 are rotatably connected to the second slider 10. A second spring 11 is fixedly connected to the upper side of the second slider 10. Under the action of the second slider 10 and the second spring 11, the auxiliary roller 12 presses the carton so that the second rubber roller 14 can move it. Pressure rollers 8 are rotatably connected to the housings 1 on both sides of the chute 18, and a first rubber roller 7 is located in the middle. First limiting grooves 3 are located on the housings 1 at both ends of the first rubber roller 7. First sliders 4 are slidably connected within the first limiting grooves 3. The first sliders 4 are rotatably connected to both ends of the first rubber roller 7. A first spring 5 is fixedly connected to the upper side of the first slider 4, and a first servo motor 6 is fixedly connected to its outer side. The output end of the first servo motor 6 is fixedly connected to the first rubber roller 7. When the first servo motor 6 starts, the first rubber roller 7 begins to rotate, driving the carton forward. Simultaneously, the pressure rollers 8 apply appropriate pressure to the other side of the carton to ensure that the carton does not deviate, thus achieving a continuous and stable conveying process.

[0019] A correction plate 16 is provided on the mounting plate 2 located on the right side of the second rubber roller 14. One end of the correction plate 16 is mounted on the mounting plate 2 by bolts, which facilitates the adjustment of the angle of the correction plate 16. A sensor 17 is embedded and connected on the mounting plate 2 located between the groove 13 and the correction plate 16. The sensor 17 is a photoelectric sensor. The sensor 17 is used to send signals to the control system to start and stop the servo motor. Its principle is existing known technology, so it will not be described in this patent.

[0020] Working principle: When in use, the carton is placed into the lifting plate 19 through the opening 22. Under the action of the compression spring 20, the carton is moved to the area below the first rubber roller 7 and the pressure roller 8. At this time, the first servo motor 6 is started, which drives the first rubber roller 7 to rotate, thereby moving the carton forward. When the carton moves to the mounting plate 2, it enters between the auxiliary roller 12 and the second rubber roller 14 and continues to move forward until it passes the sensor 17. The sensor 17 sends a signal, at which time the first servo motor 6 stops and the second servo motor 15 is started. Under the action of the second servo motor 15, the second rubber roller 14 is rotated, thereby moving the carton forward. At this time, under the action of the correction plate 16, the position of the carton is adjusted. When the carton leaves the sensor 17, the second servo motor 15 stops and the first servo motor 6 is started to continuously feed the carton.

[0021] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
