[0029] Reference Figures 1-3The feeding mechanism 3 comprises a frame 31 fixedly installed at the top front side middle of the punching and bending machine body 1, the bottom front end of the frame 31 is fixedly installed with a third motor 32, the output end of the third motor 32 is fixedly connected with a feeding assembly 33 penetrating through the frame 31, the feeding assembly 33 comprises a top disc 331 fixedly installed at the top output end of the third motor 32, the outer side of the top disc 331 is fixedly installed with electric push rods 332 at equal intervals, the outer side of the electric push rod 332 is fixedly installed with a feeding tray 333, the bottom of the feeding tray 333 is fixedly installed with an air pump 334, the input end of the air pump 334 is fixedly installed with a suction disc 335, the suction disc 335 is arranged at the top of the feeding tray 333, during use, the frame 31 is fixed at the top front side middle of the punching and bending machine body 1 to provide a mounting basis for other components, the third motor 32 located at the bottom front end of the frame 31 serves as a power source, once started, the output end of the third motor 32 will drive the feeding assembly 33 connected thereto to operate, the core component of the feeding assembly 33, the top disc 331, is stably installed at the top output end of the third motor 32 and rotates with the rotation of the third motor 32, the electric push rods 332 fixedly installed at equal intervals on the outer side of the top disc 331 can be adjusted in position as needed when the top disc 331 rotates, the feeding tray 333 installed on the outer side of the electric push rod 332 is used to carry the printing plate, during work, the operator places the printing plate on the feeding tray 333, at this time, the air pump 334 installed at the bottom of the feeding tray 333 is started, the suction disc 335 at the input end of the air pump 334 is tightly adsorbed to the printing plate under the negative pressure generated by the air pump 334 to ensure the stability of the position of the printing plate in subsequent operations, when it is needed to move the printing plate to the alignment mechanism 2, the third motor 32 drives the top disc 331 to rotate, so that the feeding tray 333 carrying the printing plate moves to the appropriate position, then the electric push rod 332 extends to push the printing plate to the alignment mechanism 2, completing the feeding process, and the process is repeated to realize continuous and efficient feeding work.

[0030] Principle and advantages: The device is equipped with a feeding mechanism 3, which significantly improves the efficiency and continuity of the device operation. During the operation of the device, the operator places the printing plate on the feeding tray 333, then starts the air pump 334 at the bottom of the feeding tray 333. The negative pressure generated by the air pump 334 works with the suction cup 335 to firmly adsorb and fix the printing plate, ensuring the stability of the printing plate position during subsequent operations. After the printing plate is fixed, the third motor 32 is started. The third motor 32 drives the electric push rod 332 at the end of the feeding tray 333 through precise power output, and moves accurately to the front of the alignment mechanism 2. At this time, the electric push rod 332 is started and stretched smoothly according to the preset stroke, pushing the printing plate on the feeding tray 333 into the alignment mechanism 2. After the pushing is completed, the air pump 334 is turned off to release the adsorption of the printing plate, and the alignment mechanism 2 is started to carry out the alignment operation of the printing plate. During the entire processing process, after the feeding of the previous printing plate is completed, the electric push rod 332 automatically retracts and resets. At the same time, the third motor 32 drives the top disc 331 to rotate, and the rotation of the top disc 331 cleverly exchanges the positions of the electric push rod 332 and the feeding tray 333 on the top disc 331, so that the feeding tray 333 on the outside is emptied, which is convenient for the operator to place a new printing plate. This cycle is repeated to realize continuous and uninterrupted feeding, greatly improving the overall operation efficiency of the device and meeting the demand for efficient feeding in large-scale production.

[0031] The positioning mechanism of the device plays a key role in the processing of the printing plate, effectively improving the adaptability and processing stability of the equipment. When the printing plate is successfully moved to the inside space of the two receiving plates 251 by the feeding mechanism 3, the first motor 23 is started, and the first motor 23 outputs strong power to drive the screw rod 22 to rotate at high speed. The screw rod 22 is specially designed, with opposite thread directions at both ends. This unique structure allows the screw rod 22 to synchronously drive the two sliders 24 to smoothly slide inside the guide rail 21 during rotation. The sliding of the slider 24 drives the two receiving plates 251 connected to it to move inward, and the receiving plates 251 gradually approach and accurately clamp the printing plate. At this time, the printing plate is located inside the two drive wheels 252. The adjustable design of this positioning mechanism allows it to flexibly adapt to printing plates of different sizes, showing excellent versatility. After the driving roller tightly contacts the outside of the printing plate, the second motor 264 is started, which drives the worm 263 to rotate. Due to the precise transmission connection relationship between the worm 263 and the worm gear 262, the rotation of the worm 263 can synchronously drive all the worm gears 262 to rotate together. The synchronous rotation of all the worm gears 262 in turn synchronously drives the drive wheels 252 inside the receiving plates 251 to rotate at high speed. The drive wheels 252 rely on strong friction to smoothly move the printing plate inside the receiving plates 251, automatically accurately feeding the printing plate into the punching and bending machine body 1 for subsequent punching and bending processing. It is worth noting that during the entire clamping and positioning process, the synchronous movement of the two sliders 24 driven by the screw rod 22 ensures that the printing plate is stably centered and clamped between the receiving plates 251. This accurate positioning method allows the device to quickly and automatically complete the alignment and processing of the printing plate during overall use, greatly improving the adaptability and processing stability of the equipment during production and processing, and providing a solid guarantee for high-quality printing plate preprocessing.
