[0062] Example 1

[0063] like Figure 1-6As shown, the present invention discloses a gravure printing machine for printing roller processing, comprising a frame 100, and further comprising a moving drive assembly, a printing assembly, a doctor blade assembly, a drying assembly, and a cleaning assembly. The moving drive assembly is mounted on the frame and can move on the frame. The printing assembly is mounted on the moving drive assembly and can move under the drive of the moving drive assembly. The doctor blade assembly is mounted on the moving drive assembly and is located above the printing assembly, and the doctor blade assembly scrapes the ink evenly. The drying assembly is mounted on the frame and is located to one side of the doctor blade assembly, and the drying assembly dries the printed material. The cleaning assembly is mounted on the moving drive assembly and is located to one side of the printing assembly, and the cleaning assembly cleans the surface of the printing assembly.

[0064] In this embodiment, the moving drive assembly includes a hydraulic cylinder 101, a guide rail 102, and a moving bracket 103. The hydraulic cylinders are provided in pairs and are symmetrically arranged on both sides of the frame. The guide rails are provided in pairs and are arranged on the frame. The moving bracket is slidably arranged on the guide rails. The two sides of the moving bracket are respectively connected to each hydraulic cylinder. The moving bracket can move on the guide rails under the drive of the hydraulic cylinders.

[0065] In this embodiment, the printing assembly includes a rotary motor 201, a rotary screw 202, a second guide rail 203, a movable seat 204, a first fixed cone 205, a first drive motor 206, a drive wheel 207, a rotating rod 208, a second fixed cone 209, a driven wheel 210, a transmission belt 211, a printing roller 212, a printing rubber roller 213, and a hydraulic motor 214. The rotary motor is mounted on a movable support, and the rotary screw is rotatably mounted on the movable support. One side of the rotary screw is connected to the rotary end of the rotary motor. A pair of second guide rails are provided, symmetrically arranged on both sides of the rotary screw. The movable seat is slidably mounted on the second guide rail, and the movable seat and the rotary screw form a threaded engagement. The first fixed cone is rotatably mounted on the movable seat, and the first fixed cone is conical in shape. The first drive motor is mounted on the movable support, with its rotary end facing inwards towards the movable support. The drive wheel is mounted on the first drive motor. On the rotating end of the machine, the driving wheel rotates with the rotating end of the drive motor. The rotating rod is rotatably mounted on the movable support. The fixed cone II is fixedly mounted on one side of the rotating rod. The fixed cone II is conical in shape and rotates with the rotating rod. The driven wheel is mounted on the rotating rod. One side of the transmission belt is sleeved on the driving wheel, and the other side of the transmission belt is sleeved on the driven wheel. The driving wheel drives the driven wheel to rotate through the transmission belt. One side of the printing roller abuts against the fixed cone I, and the other side of the printing roller abuts against the fixed cone II. Grooves are provided on both sides of the printing roller. When the fixed cone I and fixed cone II fix the printing roller, the grooves are used to abut against and accommodate the fixed cone I and fixed cone II. The printing rubber roller is rotatably mounted on the frame and is located on one side of the printing roller. The hydraulic motor is mounted on the frame, and one side of the hydraulic motor is connected to the printing rubber roller. The hydraulic motor drives the printing rubber roller to rotate.

[0066] In this embodiment, the doctor blade assembly includes a second electric push rod 301, a first guide rod 302, a blade holder 303, and a doctor blade 304. The second electric push rod is mounted on a movable support, with its telescopic end facing the printing roller.

The other side of the blade holder is connected to the telescopic end of the second electric push rod. The doctor blade is mounted on the blade holder. It is worth noting that during proofing, the doctor blade first contacts the printing roller, and then a small amount of ink is directly applied to the top of the contact point between the printing roller and the doctor blade. The printing roller rotates from the top towards the printing roller. During rotation, the ink adheres to the printing roller and is then evenly scraped by the doctor blade. The ink is then transferred to the printed material on the printing roller, thus completing the inking process. The amount of ink used is limited to a single proofing operation, preventing leakage. Furthermore, the doctor blade does not obstruct the rotation of the printing roller during contact.

[0067] In this embodiment, the drying assembly includes an electric push rod 401, a drying bracket 402, an electric heating element 403, a fan 404, and an air supply duct 405. The electric push rod 401 is mounted on the frame, and the top of the drying bracket is connected to the telescopic end of the electric push rod 402. An air outlet is located at the bottom of the drying bracket. Two pairs of electric heating elements are installed within the drying bracket. The fan is located on one side of the frame, and one side of the air supply duct is connected to the fan's outlet. The other side of the air supply duct is connected to the top of the drying bracket, delivering air to the drying bracket. This air supply duct is a flexible metal hose that can move with the drying bracket. During ink drying, the printed material must be completely dry before inspection. However, some printed materials dry slowly due to their material properties, reducing proofing efficiency. This device directly blows hot air onto the printed material, accelerating the ink drying time and shortening the single-plate-making time, thus increasing plate-making efficiency.

[0068] In this embodiment, the cleaning assembly includes an electric push rod 501, a guide rod 502, a cleaning bracket 503, and a cleaning roller 504. The electric push rod 501 is mounted on a movable bracket, with its telescopic end facing the printing roller. The guide rod 502 is mounted on the movable bracket and consists of a pair. The cleaning bracket is slidably mounted on the guide rod 502 on both sides, with one side connected to the telescopic end of the electric push rod 504. The cleaning roller is rotatably mounted on the cleaning bracket and cleans the ink on the printing roller. After proofing, the ink on the printing roller needs to be wiped off, which increases the workload of the workers. This device directly drives the cleaning roller to contact the printing roller by setting the electric push rod 501, cleaning the printing roller as it rotates, thereby directly completing the cleaning of the printing roller and reducing the workload of the workers.

[0069] Example 2

[0070] like Figure 1-8 As shown, the difference between this embodiment and embodiment 1 is that in this embodiment, a hydraulic station 601 is provided on one side of the frame. The hydraulic station is connected to the hydraulic motor and hydraulic cylinder through pipelines, and the hydraulic station provides a power source for the hydraulic motor and hydraulic cylinder. This hydraulic station is existing technology and will not be described in detail here.

[0071] The working principle of this utility model:

[0072] During processing, the printing roller is placed between fixed cone one and fixed cone two. A rotary motor drives a rotary screw to rotate. During rotation, the screw, through its threaded engagement, moves a movable seat towards the printing roller. The movable seat then moves fixed cone one to press the printing roller against fixed cone two, thus fixing the printing roller in place. The material to be printed is then adhered to the printing roller. The hydraulic cylinder's push end moves a movable bracket along guide rail one towards the printing roller. An electric push rod two moves the blade holder towards the printing roller under the guidance of guide rod one, bringing the doctor blade into contact with the printing roller. Ink is then poured onto the area above the doctor blade's contact point. A drive motor one drives a driving wheel to rotate, which in turn drives a driven wheel via a transmission belt. Simultaneously, the driven wheel rotates a rotating rod, which in turn rotates fixed cone two. This rotation of fixed cone two, in turn, causes the printing roller to rotate from above towards the printing roller. During rotation, the doctor blade scrapes off excess ink from the printing roller. Simultaneously, the hydraulic motor drives the printing roller to rotate from above towards the printing roller, transferring the ink onto the printed material on the printing roller, thus completing the proofing of the printing roller. After processing, the moving bracket moves away from the printing roller under the action of the hydraulic cylinder. At the same time, the electric push rod three moves the drying bracket downward. The electric heating tube generates heat, and the fan delivers air to the drying bracket. The electric heating tube heats the air, and the hot air is blown onto the printed material on the printing roller through the air outlet, thus drying the ink. At the same time, the hydraulic motor drives the printing roller to rotate, thus drying all areas of the printed material. Simultaneously, the electric push rod four moves the cleaning bracket towards the printing roller. The cleaning roller on the cleaning bracket cleans the rotating printing roller. After cleaning, the moving seat moves outward to remove the printing roller, completing the proofing of the printing roller.
