[0001] The utility model relates to the technical field of CTP plate-making machines, and particularly relates to an automatic anti-damage plate-turning device for a CTP plate-making machine. Background Technique

[0002] At present, offset printing is used for printed materials such as single pages, brochures, and folded pages. Before printing, the graphics and texts of the products to be printed need to be electronically color-separated, laser phototypeset, and then four CTP base color plates of red, yellow, blue, and black are generated by a plate-making machine.

[0003] In the plate-turning process of the traditional automatic plate-turning device of a CTP plate-making machine, the CTP plate is first abutted against the receiving baffle, and then one end of the CTP plate is pushed for plate-turning. Since the edge of the CTP plate contacts the receiving baffle, during the plate-turning process, the edge of the CTP plate continuously scrapes against the receiving baffle, which easily causes deformation and loss of the edge of the CTP plate and results in defective products. Summary of the Utility Model

[0004] In view of the problems existing in the above-mentioned existing automatic plate-turning device of a CTP plate-making machine, the present utility model is proposed.

Since the edge of the CTP plate contacts the receiving baffle, during the plate-turning process, the edge of the CTP plate continuously scrapes against the receiving baffle, which easily causes deformation and loss of the edge of the CTP plate and results in defective products.

[0006] In order to achieve the above purpose, the present utility model provides the following technical solutions:

[0007] An automatic anti-damage plate-turning device for a CTP plate-making machine, including a bottom plate and an L-shaped baffle. The L-shaped baffle is fixedly arranged on one side of the upper surface of the bottom plate. On the other side of the upper surface of the bottom plate, a U-shaped plate is fixedly arranged. A rotating rod is rotatably arranged inside the upper end of the U-shaped plate. A rotating strip is fixedly adjusted on the rod wall of the rotating rod. A receiving shell is fixedly arranged at one end of the rotating strip away from the rotating rod. A torsion spring is movably sleeved on the rod wall of the rotating rod. Two ends of the torsion spring are respectively fixedly connected to the corresponding rotating rod and the inner wall of the U-shaped plate. A buffer mechanism is arranged inside the receiving shell and at one end close to the L-shaped baffle. A transmission mechanism for driving the rotating rod to rotate is arranged outside the U-shaped plate.

[0008] Preferably, the transmission mechanism includes a spur gear and an incomplete gear. A transmission rod is rotatably sleeved inside the U-shaped plate and below the rotating rod. The spur gear is fixedly sleeved at the front end of the rotating rod, and the incomplete gear is fixedly sleeved at the front end of the transmission rod. The incomplete gear is meshed with the spur gear. A motor is fixedly arranged at the rear side of the U-shaped plate, and the output end of the motor is fixedly connected to the outer wall of the U-shaped plate.

[0009] Preferably, the buffer mechanism includes a buffer strip and a spring. The buffer strip is buffer-arranged on one side of the material receiving shell close to the L-shaped baffle. A through hole is formed in the outer wall of the material receiving shell close to the L-shaped baffle. A sliding rod is slidably sleeved inside the through hole. One end of the sliding rod is fixedly connected to the buffer strip. The spring is movably sleeved on the rod wall of the sliding rod, and both ends of the spring are fixedly connected to the side of the corresponding buffer strip close to the L-shaped baffle and the inner wall of the material receiving shell respectively.

[0010] Preferably, the buffer strip is a rubber strip.

[0011] Preferably, both sides of the buffer strip are in contact with the inner wall of the material receiving shell.

[0012] Preferably, an anti-drop block is fixedly arranged at one end of the sliding rod away from the buffer strip.

[0013] In the above technical solution, the technical effects and advantages provided by the present utility model are as follows:

[0014] 1. In the present utility model, after the material receiving shell receives the material, the CTP plate contacts the buffer strip and then compresses the spring, so as to buffer and protect the CTP plate. Then the motor drives the transmission rod to rotate, so that the incomplete gear drives the spur gear to rotate, that is, the material receiving shell rotates and approaches the L-shaped baffle until the open side of the material receiving shell rotates to the side close to the L-shaped baffle, so that the entire surface of the CTP plate falls on the L-shaped baffle, reducing the friction between the CTP plate and the L-shaped baffle, effectively reducing the risk of damage during the CTP plate turning process, and improving the product qualification rate.

[0015] 2. In the present utility model, after the incomplete gear is separated from the spur gear, the elastic force of the torsion spring drives the rotating rod to rotate, that is, the rotating rod drives the rotating strip to rotate to the side away from the L-shaped baffle, so as to drive the material receiving shell to reset.

[0024] An embodiment of the present utility model discloses an automatic damage - preventing plate - turning device for a CTP plate - making machine.

[0025] Referring to Figures 1-4 , an automatic damage - preventing plate - turning device for a CTP plate - making machine includes a base plate 1 and an L - shaped material - retaining plate 2. The L - shaped material - retaining plate 2 is fixedly arranged on one side of the upper surface of the base plate 1. On the other side of the upper surface of the base plate 1, a U - shaped plate is fixedly arranged. Inside the upper end of the U - shaped plate, a rotating rod 4 is rotatably arranged. A rotating strip 5 is fixedly adjusted on the rod wall of the rotating rod 4. One end of the rotating strip 5 far from the rotating rod 4 is fixedly provided with a material - receiving shell 3. A torsion spring 9 is movably sleeved on the rod wall of the rotating rod 4, and both ends of the torsion spring 9 are fixedly connected to the corresponding rotating rod 4 and the inner wall of the U - shaped plate respectively.

[0026] Referring to Figures 1-4 , a transmission mechanism for driving the rotation of the rotating rod 4 is arranged outside the U - shaped plate. The transmission mechanism includes a straight gear 6 and an incomplete gear 8. Inside the U - shaped plate and below the rotating rod 4, a transmission rod 7 is rotatably sleeved. The straight gear 6 is fixedly sleeved on the front end of the rotating rod 4. The incomplete gear 8 is fixedly sleeved on the front end of the transmission rod 7. The incomplete gear 8 is meshed with the straight gear 6. A motor 10 is fixedly arranged at the rear side of the U - shaped plate, and the output end of the motor 10 is fixedly connected to the outer wall of the U - shaped plate.

[0027] Referring to Figures 1-4, inside the material receiving housing 3 and at one end close to the L-shaped baffle 2, a buffer mechanism is provided. The buffer mechanism includes a buffer strip 11 and a spring 14. The buffer strip 11 is bufferingly arranged on one side inside the material receiving housing 3 close to the L-shaped baffle 2. On the outer wall of the material receiving housing 3 close to the L-shaped baffle 2, a through hole is opened. A sliding rod 12 is slidably sleeved inside the through hole. One end of the sliding rod 12 is fixedly connected to the buffer strip 11. The spring 14 is movably sleeved on the rod wall of the sliding rod 12.
