[0017] The sprocket assembly comprises a driving sprocket and a plurality of sprockets. The driving sprocket and the sprockets are driven by chains. The chain and the plate feeding platform, and the chain and the publishing rack are fixedly connected by a plurality of chain connecting blocks.

[0018] An operating method of a dual-drum high-speed plate-making machine is performed according to the following steps:

[0019] First, set the working template. The sensor detects and determines whether the state of the mechanical structure is consistent with the set working template. If the template is inconsistent, the corresponding mechanism template is adjusted. The plate feeder separates the plate and paper through the nozzle mechanism, and sends the plate to the plate feeding bridge mechanism through the transmission mechanism. The plate feeding bridge mechanism rises to the A drum plate feeding height position through the upper and lower transmission mechanisms. The sensor detects the A drum plate feeding height position, and the side gauge adjusts the plate centering position. The plate feeding bridge mechanism moves forward until it reaches the front and rear position of the A drum plate feeding. Then the conveyor belt sends the plate head part to the bottom of the A drum plate head clamp and starts to load the plate. The A drum plate head clamp closes and presses the plate head tightly. Then the A drum plate loading roller presses on the plate. The surface vacuum adsorption action adsorbs the plate material, and at the same time, the plate loading roller of A drum rotates with the plate material and rotates to the tail clamp part of A drum. The tail clamp of A drum opens, and A drum rotates to send the tail of the plate material into the tail clamp. The tail clamp of A drum closes and presses the plate material, and the plate feeding bridge mechanism retreats and descends to the receiving position. The scanning imaging process begins, and A drum starts scanning imaging. At the same time, the plate feeder sends the plate material to the plate feeding bridge mechanism again. The plate feeding bridge descends to the plate feeding height position of B drum through the upper and lower transmission mechanisms. The sensor detects the plate feeding height position of B drum, and the side gauge adjusts the center position of the plate material. The plate feeding bridge mechanism moves forward until it reaches the front and rear position of B drum, and then the conveyor belt sends the plate head part into The B drum plate head clamp is under and plate loading begins. The B drum plate head clamp closes and presses the plate head tightly. Then the B drum plate loading roller presses on the plate. The vacuum adsorption effect on the surface of the B drum adsorbs the plate. At the same time, the B drum plate loading roller rotates with the plate and rotates to the B drum plate tail clamp part. The B drum plate tail clamp opens, and the B drum rotates to send the plate tail into the B drum plate tail clamp. The B drum plate tail clamp closes and presses the plate tightly. The plate feeding bridge mechanism retreats and rises to the plate receiving position. The B drum plate loading is completed and is in a waiting state. After the A drum scans and images, the scanning platform is reset, and the scanning mechanism descends to the B drum scanning position. The B drum scanning imaging process begins. After the A drum scans and images, the plate delivery rack rises to the A drum. Drum unloading position, the upper computer controls the A drum to rotate to the A drum plate head clamp open position, the A drum plate loading roller presses down on the plate material, and then the A drum plate head clamp opens. After the plate material plate head is released, the A drum plate head clamp closes, and then the A drum plate loading roller rotates the A drum to a certain angle, and the plate material plate head part falls on the plate unloading swing roller, and then the plate unloading swing roller lifts the plate head to the height of the punching module entrance, and at the same time, the A drum continues to rotate to make the plate head enter the punching module, and the punching module punches the plate head. The punched aluminum sheet enters the chip removal type aluminum and is collected. After the punching is completed, the A drum reverses to make the plate head withdraw from the punching module. When the plate head withdraws to the plate unloading swing roller, the plate unloading swing roller begins to fall so that the plate head falls exactly on the publishing rack;When the leading part of the plate falls on the publishing rack, the equipment starts to further unload the plate. The A-drum plate pressing roller presses the plate and continues to rotate with the A-drum. The plate continues to be transported on the publishing rack and further transported to the plate output rack. When the plate is transported to the plate output rack, the roller on the upper part of the plate output rack presses on the plate at the same time and rotates with the plate output rack belt to transport the plate. The A-drum rotates to the tail part of the plate, the A-drum plate loading roller is lifted, the A-drum plate tail clamp is opened, and the plate leaves the A-drum along with the plate output rack. The A-drum plate tail clamp is closed, and the plate unloading is completed. The plate output rack further transports the plate out of the end of the plate rack, and the plate output rack is lowered. The plate delivery rack transports the plate material to the plate receiving rack. After the A drum has completed the plate unloading, the plate feeder and the bridge mechanism repeat the above plate feeding action. The A drum repeats the above plate loading action and waits for imaging scanning. After the B drum has completed the scanning imaging, the scanning platform is reset, and the scanning mechanism rises to the A drum scanning position. The A drum scanning imaging process begins, and the plate delivery rack descends to the B drum plate unloading position. The upper computer controls the B drum to rotate to the B drum plate head clamp open position, and the B drum plate loading roller presses down on the plate material, and then the B drum plate head clamp opens. After the plate material head is released, the B drum plate head clamp closes, and then The plate loading roller of B drum rotates a certain angle with the plate unloading roller, and the plate head part falls on the plate unloading swing roller, and then the plate unloading swing roller lifts the plate head to the entrance height of the punching module. At the same time, the B drum continues to rotate to make the plate head enter the punching module, and the punching module punches the plate head. The punched aluminum sheet enters the chip removal type aluminum and is collected. After the punching is completed, the B drum reverses to make the plate head withdraw from the punching module. When the plate head withdraws to the plate unloading swing roller, the plate unloading swing roller begins to fall so that the plate head just falls on the publishing rack. When the plate head part falls on the publishing rack, the equipment begins to further unload the plate, and the B drum plate pressing roller presses the plate material. As the B light drum continues to rotate, the plate material continues to be transported on the printing rack and further transported to the plate delivery rack. When the plate material is transported to the plate delivery rack, the roller on the upper part of the plate delivery rack presses on the plate material at the same time, and rotates with the plate delivery rack belt to transport the plate material. The B light drum rotates to the plate tail part, the B light drum plate loading roller is lifted, the B light drum plate tail clamp is opened, the plate material leaves the B light drum as the plate delivery rack is transported, the B light drum plate tail clamp is closed, the plate unloading is completed, the plate delivery rack further transports the plate material to the end of the plate delivery rack, the plate delivery rack rises to the plate delivery position, and the plate delivery rack transports the plate material to the plate collection rack. The A and B light drums operate cyclically according to the above process. ;

[0020] In this example, there are two optical drums, but not limited to two, and the double optical drums are distributed up and down, and the upper and lower optical drums are equipped with a plate head clamp, a plate tail clamp, a plate loading roller and a driving mechanism. The structure on the optical drum is the prior art and will not be described again.

[0021] The present invention provides a dual-drum high-speed platemaking machine and an operation method thereof. The platemaking equipment cooperates with a plate supply machine to adaptively adapt to different plate materials to perform a series of production processes such as automatic plate supply and loading, high-quality scanning and plate making, plate unloading and punching, etc. The A and B drums work in rotation and cycle, so that the interval time of loading and unloading the plate is fully utilized, a large amount of plate making waiting time is saved, the scanning imaging time of the optical drum is greatly improved, and thus the plate making speed is improved.

[0043] An operating method of a dual-drum high-speed plate-making machine is performed according to the following steps:

[0044] First, set the working template. The sensor detects and determines whether the state of the mechanical structure is consistent with the set working template. If the template is inconsistent, the corresponding mechanism template is adjusted. The plate feeder separates the plate and paper through the nozzle mechanism, and sends the plate to the plate feeding bridge mechanism through the transmission mechanism. The plate feeding bridge mechanism rises to the A drum plate feeding height position through the upper and lower transmission mechanisms. The sensor detects the A drum plate feeding height position, and the side gauge adjusts the plate centering position. The plate feeding bridge mechanism moves forward until it reaches the front and rear position of the A drum plate feeding. Then the conveyor belt sends the plate head part to the bottom of the A drum plate head clamp and starts to load the plate. The A drum plate head clamp closes and presses the plate head tightly. Then the A drum plate loading roller presses on the plate. The surface vacuum adsorption action adsorbs the plate material, and at the same time, the plate loading roller of A drum rotates with the plate material and rotates to the tail clamp part of A drum. The tail clamp of A drum opens, and A drum rotates to send the tail of the plate material into the tail clamp. The tail clamp of A drum closes and presses the plate material, and the plate feeding bridge mechanism retreats and descends to the receiving position. The scanning imaging process begins, and A drum starts scanning imaging. At the same time, the plate feeder sends the plate material to the plate feeding bridge mechanism again. The plate feeding bridge descends to the plate feeding height position of B drum through the upper and lower transmission mechanisms. The sensor detects the plate feeding height position of B drum, and the side gauge adjusts the center position of the plate material. The plate feeding bridge mechanism moves forward until it reaches the front and rear position of B drum, and then the conveyor belt sends the plate head part into The B drum plate head clamp is under and plate loading begins. The B drum plate head clamp closes and presses the plate head tightly. Then the B drum plate loading roller presses on the plate. The vacuum adsorption effect on the surface of the B drum adsorbs the plate. At the same time, the B drum plate loading roller rotates with the plate and rotates to the B drum plate tail clamp part. The B drum plate tail clamp opens, and the B drum rotates to send the plate tail into the B drum plate tail clamp. The B drum plate tail clamp closes and presses the plate tightly. The plate feeding bridge mechanism retreats and rises to the plate receiving position. The B drum plate loading is completed and is in a waiting state. After the A drum scans and images, the scanning platform is reset, and the scanning mechanism descends to the B drum scanning position. The B drum scanning imaging process begins. After the A drum scans and images, the plate delivery rack rises to the A drum. At the photodrum unloading position, the upper computer controls the A photodrum to rotate to the A photodrum plate head clamp open position, the A photodrum plate loading roller presses down on the plate material, and then the A photodrum plate head clamp opens. After the plate material plate head is released, the A photodrum plate head clamp closes, and then the A photodrum plate loading roller rotates a certain angle with the A photodrum, and the plate material plate head part falls on the plate unloading swing roller, and then the plate unloading swing roller lifts the plate head to the height of the punching module entrance, and at the same time, the A photodrum continues to rotate to make the plate head enter the punching module, and the punching module punches the plate head.

When the plate head withdraws to the plate unloading swing roller, the plate unloading swing roller begins to fall so that the plate head just falls on the publishing rack;

[0045] When the leading part of the plate falls on the publishing rack, the equipment starts to further unload the plate. The A-drum plate pressing roller presses the plate and continues to rotate with the A-drum. The plate continues to be transported on the publishing rack and further transported to the plate output rack.

After the B drum has completed the scanning imaging, the scanning platform is reset, and the scanning mechanism rises to the A drum scanning position.

At the same time as A drum starts scanning and imaging, the plate feeder sends the plate to the plate feeding bridge mechanism again, and the plate feeding bridge descends to the plate feeding height of B drum through the upper and lower transmission mechanisms. The sensor detects the height position of the plate supply of B drum, and the side gauge adjusts the center position of the plate. The plate feeding bridge mechanism moves forward until it reaches the front and rear position of the plate supply of B drum, and then the conveyor belt sends the head part of the plate under the head clamp of B drum and starts to load the plate. The head clamp of B drum closes and presses the head of the plate, and then the plate loading roller of B drum presses on the plate, and the vacuum adsorption effect on the surface of B drum adsorbs the plate. At the same time, the plate loading roller of B drum rotates with the plate and rotates to the tail clamp of B drum. The tail clamp of B drum opens, and the rotation of B drum sends the tail of the plate into the tail clamp of B drum. The tail clamp is closed to press the plate, the plate feeding bridge mechanism retreats and rises to the receiving position, the B drum is in a waiting state after the plate loading is completed, and the scanning platform is reset, the scanning mechanism descends to the scanning position of the B drum, and the scanning imaging process of the B drum begins. After the scanning imaging of the A drum is completed, the publishing rack rises to the A drum plate unloading position, and the upper computer controls the A drum to rotate to the A drum plate head clamp open position, the A drum plate loading roller is pressed down on the plate, and then the A drum plate head clamp is opened. After the plate head is released, the A drum plate head clamp is closed, and then the A drum plate loading roller rotates a certain angle with the A drum. The plate head part falls on the plate unloading swing roller, and then the plate unloading swing roller lifts the plate head to the height of the punching module entrance. At the same time, the A optical drum continues to rotate to make the plate head enter the punching module. The punching module punches holes in the plate head, and the punched aluminum sheet enters the chip removal type aluminum to be collected. After the punching is completed, the A optical drum reverses to make the plate head withdraw from the punching module. When the plate head withdraws to the plate unloading swing roller, the plate unloading swing roller starts to fall so that the plate head falls exactly on the publishing rack; When the head part of the plate falls on the publishing rack, the equipment starts to further unload the plate, and the A-drum plate pressing roller presses the plate and continues to rotate with the A-drum. The plate continues to be transported on the publishing rack and further transported to the publishing rack. When the plate is transported to the publishing rack, the roller on the upper part of the publishing rack presses on the plate at the same time and rotates with the publishing rack belt to transport the plate. The A-drum rotates to the tail part of the plate, the A-drum plate loading roller is lifted, the A-drum plate tail clamp opens, and the plate leaves the A-drum as the publishing rack is transported. The A-drum plate tail clamp closes, and the plate unloading is completed. The publishing rack further transports the plate to the end of the publishing rack, and the publishing rack descends to the plate exit position. The publishing rack transports the plate to the plate collection rack. After the A-drum plate unloading is completed, the plate feeder and the bridge mechanism repeat the above plate feeding action, and the A-drum repeats the above plate loading action and waits for imaging. Scanning, after the B drum scans and images, the scanning platform is reset, the scanning mechanism rises to the A drum scanning position, the A drum scanning and imaging process begins, the publishing rack descends to the B drum plate unloading position, the upper computer controls the B drum to rotate to the B drum plate head clamp open position, the B drum plate loading roller presses down on the plate material, and then the B drum plate head clamp opens. After the plate material plate head is released, the B drum plate head clamp closes, and then the B drum plate loading roller rotates a certain angle with the B drum, and the plate material plate head part falls on the plate unloading swing roller, and then the plate unloading swing roller lifts the plate head to the height of the punching module entrance, and at the same time, the B drum continues to rotate to make the plate head enter the punching module, the punching module punches the plate material, and the punched aluminum sheet enters the chip removal type aluminum to be collected. After the punching is completed, the B drum reverses to make the plate head exit from the punching module; When the plate head exits onto the plate unloading swing roller, the plate unloading swing roller begins to fall so that the plate head just falls on the publishing rack. When the plate head partially falls on the publishing rack, the equipment begins to further unload the plate. The B light drum plate pressing roller presses the plate material and continues to rotate with the B light drum. The plate material continues to be transported on the publishing rack and is further transported to the publishing rack. When the plate material is transported to the publishing rack, the roller on the upper part of the publishing rack presses on the plate material at the same time, and rotates with the publishing rack belt to transport the plate material. The B light drum rotates to the tail part of the plate, the B light drum plate loading roller is lifted, the B light drum plate tail clamp opens, and the plate material leaves the B light drum as the publishing rack is transported. The B light drum plate tail clamp closes, and the plate unloading is completed. The publishing rack further transports the plate material to the end of the publishing rack. The publishing rack rises to the plate exit position, and the publishing rack transports the plate material to the plate collection rack. The A and B light drums operate cyclically according to the above process.
