Description

Technical Field

[0001] This utility model relates to a plate feeding buffer device for a printing plate making machine, belonging to the technical field of printing plate making equipment. Background Technology

[0002] In modern printing plate making, when an aluminum CTP plate with dimensions of 1160mm×1040mm×0.2mm enters the plate-making machine via a belt conveyor system, the high-speed movement and the mechanical gripper of the plate-making machine generate a rigid impact, with an impact force of up to 50-80N, leading to the following problems: (1) The photosensitive adhesive layer on the surface is scratched or peeled off due to impact; (2) The ultra-thin aluminum plate undergoes plastic deformation, and the deformation amount is 0.05-0.1 mm; (3) The positioning deviation of the plate material causes an error of 0.1-0.3mm in the position of the pattern; (4) The overprinting error is greater than 0.05mm, which is below the industry standard and the accuracy is exceeded.

[0003] Existing buffer devices mostly use rigid grooves with fixed angles or single rubber pads, which can only provide static buffering and cannot dynamically adjust the buffering effect according to the plate conveying speed and impact force. The buffering efficiency is low and it is easy to generate secondary vibration, making it difficult to meet the requirements of high-precision plate making. Utility Model Content

[0004] The purpose of this invention is to provide a plate feeding buffer device for a printing plate making machine, which has a good buffering effect, can meet the plate making machine's plate requirements, and solves the problems existing in the background art.

[0005] The technical solution of this utility model is: A plate feeding buffer device for a printing plate-making machine is provided. This device is positioned between a CTP plate conveyor belt and the plate-making machine's rotating hub. It includes a base, a buffer, a middle support seat, telescopic rods, springs, a conveyor plate, rubber anti-slip blocks, a support frame, and anti-slip wheels. The middle support seat and the support frame are fixed to the base via the buffer. The support frame has rubber anti-slip blocks that mate with the CTP plates conveyed from the CTP plate conveyor belt. The conveyor plate is fixed at an angle to the middle support seat. One end of the conveyor plate connects to the support frame, and the other end connects to the plate-making machine's rotating hub. The end of the conveyor plate closer to the rotating hub is higher than the end closer to the support frame. The conveyor plate has anti-slip wheels that mate with the CTP plates. Several telescopic rods are provided between the conveyor plate and the middle support seat, and each telescopic rod has a spring.

[0006] The tilt angle of the conveyor plate is 15°.

[0007] The anti-slip wheels on the conveyor plate are rotatably connected to the CTP plate.

[0008] A sensor is installed at one end of the conveyor plate near the support frame.

[0009] Using this invention, the CTP plate, conveyed from the CTP plate conveyor belt, enters the support frame and is slowed down by the action of the rubber anti-slip block. Then, it enters the plate-making machine hub through the conveyor plate. The impact force of the CTP plate entering the plate-making machine hub is reduced by the buffering of the telescopic rod and spring between the conveyor plate and the middle support seat.

[0010] The beneficial effects of this invention are: it can reduce the transmission speed of CTP plates, reduce impact force, and provide good buffering effect, thus meeting the requirements of plate-making machines. Attached Figure Description

[0012] The present invention will be further described below with reference to the accompanying drawings and examples.

[0013] See attached document Figure 1-3 A plate feeding buffer device for a printing plate making machine is provided. This device is positioned between a CTP plate conveyor belt 15 and a plate making machine hub 12. It includes a base 1, a buffer 2, a middle support 3, telescopic rods 4, springs 5, a conveyor plate 6, rubber anti-slip blocks 8, a support frame 9, and anti-slip wheels 10. The middle support 3 and the support frame 9 are respectively fixed to the base 1 via the buffer 2. The support frame 9 is provided with rubber anti-slip blocks 8 that cooperate with the CTP plate 16 conveyed from the CTP plate conveyor belt 15. The conveyor plate 6 is fixed at an angle to the middle support 3. One end of the conveyor plate 6 is connected to the support frame 9, and the other end is connected to the plate making machine hub 12. The end of the conveyor plate 6 closer to the plate making machine hub 12 is higher than the end closer to the support frame 9. The conveyor plate 6 is provided with anti-slip wheels 10 that cooperate with the CTP plate 16. Several telescopic rods 4 are provided between the conveyor plate 6 and the middle support 3, and each telescopic rod 4 is provided with a spring 5.

[0014] In this embodiment, refer to the appendix Figure 1-3The buffer device includes a base 1, a buffer 2, a middle support 3, a telescopic rod 4, a spring 5, a conveyor plate 6, a support 7, a rubber anti-slip block 8, a support frame 9, anti-slip wheels 10, and a sensor 11. The support frame 9 is connected to the CTP plate conveyor belt 15, and the rubber anti-slip block 8 is installed on the support frame 9. The middle support 3, telescopic rod 4, spring 5, conveyor plate 6, support 7, and anti-slip wheels 10 are combined to form the first-level buffer of the CTP plate. The conveyor plate 6 has an inclination angle of 15° and is connected to the plate-making machine hub 12. The base 1 and the buffer 2 constitute the second-level buffer of the CTP plate. The buffer 2 is a commonly used buffer and shock absorption device in this field.

[0015] The support frame 9 has rubber anti-slip blocks 8 evenly distributed on its surface, which can slow down the CTP version before it is bitten by the high-speed impact machine.

[0016] When the CTP plate enters the buffer area, the sensor 11 senses the CTP plate passing by and immediately activates the anti-slip rollers 10 of the conveyor plate 6 to reduce the speed of the CTP plate for the second time. At the same time, the support spring 4 begins to move back and forth to reduce the impact force when the CTP plate is running at high speed, ensuring that the CTP plate can be accurately delivered to the mechanical gripper 13 of the plate-making machine. The mechanical gripper 13 engages with the CTP plate, the plate-making machine hub 12 begins to rotate, and plate making begins.
