[0004] In view of the above problems, the utility model provides an output bracket for a carton printing machine. Content of the Utility Model

[0005] The purpose of the utility model is to provide an output bracket for a carton printing machine. By adjusting the width of the transmission path of the output bracket, it is convenient to transmit carton boards of different specifications, improve the scope of application and practicability, and thus solve the problems in the background technique.

[0006] To achieve the above purpose, the utility model provides the following technical solution: An output bracket for a carton printing machine includes two symmetrically arranged support plates. There are two symmetrically arranged connecting plates between the two support plates. A bidirectional threaded screw rod is penetrated inside the lower ends of the two connecting plates. One end of the bidirectional threaded screw rod is provided with a first motor. A number of uniformly distributed first rollers are horizontally arranged in a straight line between the two connecting plates. Second rollers are symmetrically arranged on both sides of the first roller. The two second rollers on both sides can move synchronously towards or away from each other relative to the first roller. A second motor is arranged outside the connecting plate, and the second motor drives all the first rollers and the second rollers to rotate synchronously in the same direction.

A bidirectional threaded screw rod and a guide rod are respectively arranged on both sides inside the two movable plates. Both ends of the guide rod are fixedly connected to the side surface of the support plate. Both ends of the bidirectional threaded screw rod are rotatably connected to the inside of the support plate through bearings. The first motor is fixedly installed outside the support plate and the output shaft is fixedly connected to one end of the bidirectional threaded screw rod. The bidirectional threaded screw rod is threadedly connected to the inside of the movable plate, and the guide rod is slidably connected to the inside of the movable plate.

[0008] Further, rectangular grooves are symmetrically opened inside both ends of the first roller. Rectangular plates are fixedly arranged at the adjacent ends of the two second rollers on both sides. The rectangular plates are slidably connected to the inner surface of the rectangular grooves. A spring is tightly connected between the inner end of the rectangular plate and the inner side wall of the rectangular groove. Shafts are fixedly arranged at the opposite ends of the two second rollers on both sides.

[0020] To solve the technical problem of how to effectively transmit, as Figures 1-4 shown, the following preferred technical solutions are provided:

[0021] An output bracket of a carton printing machine includes two symmetrically arranged support plates 1. Between the two support plates 1, two symmetrically arranged connecting plates 7 are provided. Inside the lower ends of the two connecting plates 7, a bidirectional threaded screw rod 2 is penetrated. One end of the bidirectional threaded screw rod 2 is provided with a first motor 4. A number of uniformly distributed first rollers 8 are horizontally arranged in a straight line between the two connecting plates 7. Second rollers 12 are symmetrically arranged on both sides of the first roller 8. The second rollers 12 on both sides can move synchronously towards or away from the first roller 8. A second motor 14 is arranged outside the connecting plate 7. The second motor 14 drives all the first rollers 8 and the second rollers 12 to rotate synchronously in the same direction.

[0022] Specifically, during use, the output bracket is moved and fixed at the discharge port of the printing machine. Then, the second motor 14 is started to drive all the first rollers 8 and the second rollers 12 to rotate synchronously in the same direction. The carton board is placed on the first rollers 8 and the second rollers 12 for transmission. If a larger carton board needs to be transmitted, at this time, the first motor 4 is started to drive the bidirectional threaded screw rod 2 to rotate. The rotation of the bidirectional threaded screw rod 2 drives the second rollers 12 on both sides to move synchronously away from the first roller 8 through the connecting plates 7 on both sides. Then, the first motor 4 is turned off to increase the transmission path width and facilitate the transmission of large carton boards. The purpose of such a design is to adjust the transmission path width of the output bracket to facilitate the transmission of carton boards of different specifications, and improve the scope of application and practicability.

[0023] Furthermore, as Figure 1 and Figure 2 shown, the following preferred technical solutions are provided:

[0024] A movable plate 6 is fixedly provided at the middle part of the bottom end of the connecting plate 7, and a bidirectional threaded screw 2 and a guide rod 3 are respectively arranged on both sides of the two movable plates 6. Both ends of the guide rod 3 are fixedly connected to the side of the support plate 1, and the outer sides of both ends of the bidirectional threaded screw 2 are rotatably connected to the inside of the support plate 1 through bearings. The first motor 4 is fixedly installed on the outside of the support plate 1 and the output shaft is fixedly connected to one end of the bidirectional threaded screw 2. The bidirectional threaded screw 2 is threadedly connected to the inside of the movable plate 6, and the guide rod 3 is slidably connected to the inside of the movable plate 6. The purpose of this design is that the first motor 4 drives the bidirectional threaded screw 2 to rotate, and then drives the connecting plates 7 on both sides to move toward or away from each other synchronously.

[0025] Further, such as Figures 1-4 As shown, the following preferred technical solutions are provided:

[0026] Rectangular grooves 9 are symmetrically provided inside the two ends of the first roller 8, and rectangular plates 11 are fixedly provided at the proximal ends of the second rollers 12 on both sides. The rectangular plates 11 are slidably connected to the inner surfaces of the rectangular grooves 9, and springs 10 are tightly connected between the inner ends of the rectangular plates 11 and the inner walls of the rectangular grooves 9. Rotating shafts 13 are fixedly provided at the opposite ends of the second rollers 12 on both sides, and the outer sides of the rotating shafts 13 are rotatably connected to the inside of the connecting plates 7 through bearings. The purpose of such a design is to ensure that the first roller 8 and the second roller 12 can rotate synchronously in the same direction, and the connecting plates 7 on both sides drive the second rollers 12 on both sides to move synchronously toward or away from the first roller 8. At this time, the first roller 8 is in its original position under the action of the spring 10.

[0027] Further, such as Figures 1-4 As shown, the following preferred technical solutions are provided:

[0028] One side of the rotating shaft 13 extends away from one end of the second roller 12 to the outside of the connecting plate 7 and is fixedly installed with a single or multiple pulleys 15, and the pulleys 15 are connected to each other through a belt 16. A second motor 14 is fixedly installed on the outside of the connecting plate 7 and its output shaft is fixedly connected to one end of the rotating shaft 13. The purpose of this design is that the second motor 14 starts and drives all the first rollers 8 and the second rollers 12 to rotate synchronously in the same direction.

[0029] Further, such as Figure 1 As shown, the following preferred technical solutions are provided:

[0030] Universal wheels 5 are fixedly mounted on both sides of the bottom end of the support plate 1. The purpose of this design is to facilitate the movement and position fixation of the output bracket.

[0031] Further, such as Figure 1 As shown, the following preferred technical solutions are provided:

[0032] The outer surfaces of the first roller 8 and the second roller 12 are processed to have a certain degree of roughness. The purpose of such design is to improve the transmission stability of the first roller 8 and the second roller 12.

[0033] In summary: During use, move and fix the output bracket at the discharge port of the printing press. Then, start the second motor 14 and drive all the first rollers 8 and the second rollers 12 to rotate synchronously in the same direction. The cardboard is placed on the first rollers 8 and the second rollers 12 for conveying. If a relatively large cardboard needs to be conveyed, at this time, start the first motor 4 and drive the double-threaded screw rod 2 to rotate. The rotation of the double-threaded screw rod 2 drives the second rollers 12 on both sides to move away from the first rollers 8 synchronously through the connecting plates 7 on both sides. Then, turn off the first motor 4 to increase the width of the transmission path and facilitate the conveyance of large cardboard. The purpose of this design is to adjust the width of the transmission path of the output bracket to facilitate the conveyance of cardboard of different specifications, improve the scope of application and practicality.
