Description

Technical Field

[0001] The present application relates to the field of printing equipment technology, and in particular to a plate unloading device for a CTP platemaking machine. Background Art

[0002] The CTP platemaking machine forms a latent image of the image by laser scanning the engraved plate and then printing the plate. After development, the image information on the host computer screen is restored on the printing plate for direct printing by the offset printing machine.

[0003] The CTP platesetter is equipped with an inlet and an outlet. Printing plates enter the machine through the inlet for platemaking, and exit through the outlet after platemaking is complete. Existing CTP platesetters have a receiving bin at the outlet, into which printing plates slide directly. When the bin reaches a certain number of plates, the box is moved to the next processing location. This process can easily cause wear and tear on both the plates already in the bin, affecting subsequent printing quality.

[0004] With respect to the above-mentioned related technologies, the inventor believes that the printing plate is easily damaged during the process of sliding into the material receiving box, thereby affecting the subsequent printing quality. Utility Model Content

[0008] By adopting the above technical solution, the first electric telescopic rod drives the receiving plate to rise and fall, thereby receiving the printing plate that slides off the guide plate. The buffer mechanism cushions the sliding printing plate, thereby reducing the occurrence of collisions between the printing plates. The placement mechanism places the protective pad from the storage mechanism on the upper surface of the printing plate above the receiving plate, so that subsequent sliding printing plates fall onto the protective pad, reducing the occurrence of collisions between printing plates and thereby improving subsequent printing quality.

[0009] Preferably, the storage mechanism includes a storage box, a second electric telescopic rod and a push plate arranged on the transport vehicle, the storage box is a top-opening structure, the second electric telescopic rod and the push plate are both arranged in the storage box, one end of the second electric telescopic rod is connected to the bottom of the storage box, and the other end is connected to the push plate, and the protective pad is placed on the push plate.

[0010] By adopting the above technical solution, the second electric telescopic rod drives the push plate to rise, so that the protective pad on the push plate extends out of the storage box, thereby facilitating the placement mechanism to place the protective pad above the printing plate.

[0012] By adopting the above technical solution, the third electric telescopic rod drives the push plate to push the protective pad extending out of the storage box to the upper surface of the printing plate on the receiving plate, thereby protecting the printing plate on the receiving plate.

[0014] By adopting the above technical solution, when the printing plate falls onto the receiving plate, the first electric telescopic rod drives the receiving plate to descend, and the clamping assembly drives the protective pad to move above the printing plate. Then, the clamping assembly releases the protective pad, causing the protective pad to fall above the printing plate, thereby reducing the wear on the printing plate caused by the sliding process of the protective pad and further improving the subsequent printing quality.

[0015] Preferably, the buffer mechanism includes a limiting plate provided on the receiving plate, a buffer plate, and a buffer spring provided on the limiting plate, and one end of the buffer spring away from the limiting plate is connected to the buffer plate.

[0016] Preferably, a damping telescopic rod is provided in the buffer spring, one end of the damping telescopic rod is connected to the limiting plate, and the other end is connected to the buffer plate.

[0018] Preferably, an elastic buffer pad is provided on the buffer plate.

[0019] By adopting the above technical solution, the elastic buffer pad protects the sliding printing plate, further reducing the phenomenon of collision of the printing plate.

[0024] 2.

[0029] The following is combined with Figure 1-3 This application is described in further detail.

[0030] The embodiment of the present application discloses a plate unloading device for a CTP platemaking machine.

[0031] Reference Figure 1 、 Figure 2 and Figure 3 A plate unloading device for a CTP platemaking machine includes a guide plate 11 fixedly mounted at the discharge port of the CTP platemaking machine 1, a transport vehicle 2, a first electric telescopic rod 21 fixedly mounted on the transport vehicle 2, a receiving plate 22 fixedly connected to the first electric telescopic rod 21, a buffer mechanism 3 disposed at the end of the receiving plate 22 remote from the guide plate 11, a protective pad 4 disposed on the transport vehicle 2, a storage mechanism 5 for storing the protective pad 4, and a placement mechanism 6 for placing the protective pad 4. The receiving plate 22 is used to receive the printing plate, and the placement mechanism 6 places the protective pad 4 on the upper surface of the printing plate located on the receiving plate 22. A limit stopper 23 is fixedly mounted at the end of the receiving plate 22 remote from the placement mechanism 6.

[0032] The storage mechanism 5 comprises a storage box 51 fixed to the transport vehicle 2, a second electric telescopic rod 52, and a pusher plate 53. The storage box 51 is open at the top, and both the second electric telescopic rod 52 and the pusher plate 53 are located within the storage box 51. One end of the second electric telescopic rod 52 is fixedly connected to the bottom of the storage box 51, and the other end is fixedly connected to the pusher plate 53. The protective pad 4 is placed on the pusher plate 53. The second electric telescopic rod 52 drives the pusher plate 53 upward, allowing the protective pad 4 on the pusher plate 53 to extend out of the top of the storage box 51, facilitating the placement mechanism 6 to push the protective pad 4 onto the printing plate.

[0033] The placement mechanism 6 includes a mounting plate 61 fixed to the side wall of the storage box 51, a third electric telescopic rod 62 fixed to the mounting plate 61, and a push plate 63. The third electric telescopic rod 62 is fixedly connected to the push plate 63. The mounting plate 61 and the push plate 63 are both located at the opening of the storage box 51. The push plate 63 is used to push the protective mat 4 onto the receiving plate 22.

[0034] A clamping assembly 7 is provided on the push plate 63, and the clamping assembly 7 includes a fixed splint 71 fixedly provided on one end of the push plate 63 close to the mounting plate 61, a fixed plate 72 fixedly provided on the end of the push plate 63 away from the mounting plate 61, a fourth electric telescopic rod 73 fixedly provided on the fixed plate 72, a movable splint 74 fixedly connected to the fourth electric telescopic rod 73 and a clamping groove 75 opened on the protective pad 4, and the fixed splint 71 is inserted into the clamping groove 75.

[0035] The buffer mechanism 3 includes a limit plate 31 fixedly disposed on the receiving plate 22 , a buffer plate 32 and a buffer spring 33 fixedly disposed on the limit plate 31 . One end of the buffer spring 33 away from the limit plate 31 is fixedly connected to the buffer plate 32 .

[0036] The buffer spring 33 is provided with a damping telescopic rod 34, one end of which is fixedly connected to the limit plate 31, and the other end is fixedly connected to the buffer plate 32. An elastic buffer pad 35 is fixedly provided on the side of the buffer plate 32 away from the buffer spring 33.

[0037] The implementation principle of the plate unloading device of a CTP platemaking machine in an embodiment of the present application is as follows: the printing plate slides onto the receiving plate 22 through the material guide plate 11, and the end of the printing plate away from the material guide plate 11 abuts against the buffer pad of the buffer mechanism 3, and the buffer spring 33 and the damping telescopic rod 34 absorb the potential energy of the printing plate sliding, thereby reducing the phenomenon of bumping during the sliding process of the printing plate. The second electric telescopic rod 52 pushes the pushing plate 53 to rise, so that the protective pad 4 on the pushing plate 53 extends out of the storage box 51, and then the third electric telescopic rod 62 drives the pushing plate 63 to move in the direction close to the protective pad 4, so that the fixed clamping plate 71 is engaged with the clamping groove 75, and the fourth electric telescopic rod 73 drives the movable clamping plate 74 to move in the direction close to the protective pad 4 to clamp the protective pad 4. The third electric telescopic rod 62 drives the pushing plate 63 and the protective pad 4 to move in the direction close to the receiving plate 22, placing the protective pad 4 above the printing plate, so that the protective pad 4 protects the printing plate on the receiving plate 22. When the printing plate on the guide plate 11 slides onto the receiving plate 22, the sliding printing plate abuts against the protective pad 4, thereby reducing the collision between the sliding printing plate and the printing plate placed above the receiving plate 22.

[0038] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
