Description

Technical Field

[0001] This invention relates to the field of rolling mill technology, specifically to a rolling mill cleaning device for CTP plate base casting and rolling. Background Technology

[0002] In the production of CTP printing plates, casting and rolling is one of the key forming processes. As the core component of the casting and rolling equipment, the surface condition of the rolls directly affects the surface quality, thickness uniformity, and subsequent printing performance of the printing plate material. During continuous production, aluminum shavings, oil stains, oxides, or other process residues easily adhere to the surface of the rolls. If not cleaned in time, this will not only reduce the service life of the rolls but may also lead to defects such as scratches, indentations, or uneven coating on the printing plate surface, seriously affecting the yield and printing accuracy.

[0003] Currently, the industry primarily uses methods such as manual wiping during roll cleaning, high-pressure air blowing, or fixed spray cleaning for cleaning rolls. However, manual wiping is inefficient, labor-intensive, and difficult to achieve continuous online cleaning; while high-pressure air blowing can remove some floating dust, it has limited effectiveness against adhesive stains and can easily cause secondary dust re-entrainment; fixed spray systems suffer from problems such as high liquid consumption, uneven distribution of cleaning liquid, and inability to dynamically adhere to the rolling mill as it rotates, and may also affect the operational safety of surrounding equipment due to liquid splashing; furthermore, most existing fixed spray cleaning systems use liquid pumps for liquid supply, requiring an additional power source. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to overcome the existing defects and provide a roller cleaning device for CTP plate base casting and rolling. The device has a reasonable structure, is easy to operate, and is highly efficient in cleaning. By linking the drive component and the suction component, the rotation of the roller itself drives the roller and eccentric rod to rotate, which in turn drives the piston to reciprocate to achieve automatic suction and supply of cleaning fluid. No additional power source is required, saving energy and improving the integration and operating efficiency of the equipment. It is particularly suitable for online automatic cleaning of the roller surface during the CTP plate base casting and rolling process, and can effectively solve the problems in the background technology.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a CTP plate base casting and rolling roll cleaning device, comprising a support frame, the support frame being disposed near the end of the roll, a drive assembly that rolls with the roll being connected to the upper part of the support frame, the support frame having a groove, a suction assembly that can move toward the roll being slidably disposed in the groove, the suction assembly being connected to a suction pipe, and the suction pipe being connected to a cleaning component that is in contact with and wipes the roll; The drive assembly includes a support plate, which is rotatably connected to a rotating shaft via a bearing. One end of the rotating shaft is provided with a roller, and the other end of the rotating shaft is provided with a fixed plate. An eccentric rod is rotatably connected to the end of the fixed plate. The suction assembly includes a cylinder, a piston is adapted inside the cylinder, the cylinder is connected to the suction tube, a return spring is provided inside the cylinder, the return spring is away from the suction tube, the two ends of the return spring respectively contact the piston and the inner end of the cylinder, and a steel rope is connected between the piston and the eccentric rod, the steel rope passes through the return spring and the through hole at the end of the cylinder. When the roller drives the roller to rotate, the roller drives the eccentric rod to rotate. The eccentric rod, through the steel rope, causes the piston to reciprocate under the action of the return spring. The suction tube intermittently draws in the cleaning liquid and sends it into the cleaning part.

[0006] Preferably, the cleaning component includes a housing, a sponge block is provided inside the housing, and the liquid suction tube is connected to the housing through multiple connecting tubes.

[0007] Preferably, the outer wall of the cylinder has a slider that slides in cooperation with the groove of the support frame, and the groove is also provided with a spring that orients the cylinder toward the roller.

[0008] Preferably, the support plate and the support frame are connected by a pin, and the support plate and the support frame are also connected by a tension spring that keeps the roller in contact with the roll. The two ends of the tension spring are respectively connected to the support plate and the support frame.

[0009] Preferably, the length of the sponge block is greater than the length of the roller, and the sponge block has a detachable structure, which is fixed in the housing by means of buckles or magnetic attraction.

[0010] Preferably, the housing has an opening on the side near the roller, and flexible scrapers are provided at the top and bottom of the opening edge.

[0011] Preferably, one end of the suction tube is connected to the storage tank, and a one-way valve is provided near the inlet of the suction tube.

[0012] Preferably, the outer periphery of the roller is covered with a wear-resistant rubber layer or a polyurethane layer.

[0013] Compared with existing technologies, the advantages of this invention are as follows: By linking the drive component and the suction component, the rotational motion of the roller itself drives the roller and eccentric rod to rotate, thereby driving the piston to reciprocate and achieve automatic suction and supply of cleaning fluid. No additional power source is required, saving energy and improving equipment integration and operating efficiency. The cleaning component adopts a sponge block combined with a flexible scraper structure, which can not only continuously supply liquid through the suction pipe to keep it moist to effectively dissolve and absorb residues on the roller surface, but also perform secondary scraping on the roller surface through the upper and lower flexible scrapers to improve the thoroughness of cleaning and avoid stains from affecting the quality of subsequent CTP substrates. This invention has a reasonable structure, is easy to operate, and is highly efficient in cleaning. It is particularly suitable for online automatic cleaning of the roller surface during the CTP substrate casting and rolling process, effectively improving product quality and production efficiency.

Detailed Implementation

[0016] The present invention can be explained in detail through the following embodiments. The purpose of disclosing the present invention is to protect all technical improvements within the scope of the present invention. In the description of the present invention, it should be understood that if there are terms such as "upper", "lower", "front", "rear", "left", "right" indicating the orientation or positional relationship, they are only corresponding to the drawings of this application for the convenience of describing the present invention, and are not intended to indicate or imply that the device or element referred to must have a specific orientation.

[0017] Please see Figure 1-3 The present invention provides a technical solution: a CTP plate base casting and rolling roll cleaning device, including a support frame 2, the support frame 2 is arranged near the end of the roll, the upper part of the support frame 2 is connected to a drive component 1 that rolls with the roll, the support frame 2 has a groove, a suction component 3 that can move toward the roll is slidably fitted in the groove, the suction component 3 is connected to a suction pipe 4, and the suction pipe 4 is connected to a cleaning component 5 that is in contact with the roll and wipes the roll; The drive assembly 1 includes a support plate 1.5, which is rotatably connected to a rotating shaft 1.2 via a bearing. One end of the rotating shaft 1.2 is provided with a roller 1.1, and the other end of the rotating shaft 1.2 is provided with a fixing plate 1.3. An eccentric rod 1.4 is rotatably connected to the end of the fixing plate 1.3. When the roller rotates, it drives the roller 1.1 to rotate. The roller 1.1 drives the eccentric rod 1.4 to rotate via the rotating shaft 1.2 and the fixing plate 1.3. The eccentric rod 1.4 is not coaxial with the rotating shaft 1.2. The suction assembly 3 includes a cylinder 3.3, a piston 3.4 adapted inside the cylinder 3.3, the cylinder 3.3 is connected to the suction tube 4, and a return spring 3.1 is provided inside the cylinder 3.3. The return spring 3.1 is away from the suction tube 4, and the two ends of the return spring 3.1 respectively abut against the piston 3.4 and the inner end of the cylinder 3.3. A steel rope 3.2 is connected between the piston 3.4 and the eccentric rod 1.4. The steel rope 3.2 passes through the return spring 3.1 and the through hole at the end of the cylinder 3.3. When the roller drives the roller 1.1 to rotate, the roller 1.1 drives the eccentric rod 1.4 to rotate. The eccentric rod 1.4, through the steel rope 3.2, causes the piston 3.4 to reciprocate under the action of the return spring 3.1. The suction pipe 4 intermittently sucks up the cleaning liquid and sends it into the cleaning part 5. It is understandable that the rotation of the roller itself drives the roller 1.1 to rotate, which in turn drives the eccentric rod 1.4 to rotate. During the rotation, the eccentric rod 1.4 will intermittently move closer to or further away from the suction component 3. The eccentric rod 1.4 then pulls and releases the piston 3.4 through the steel rope 3.2. Due to the action of the return spring 3.1, the piston 3.4 reciprocates within the cylinder 3.3, realizing intermittent suction and liquid supply without external power. The structure is ingenious, energy-saving and efficient. Installed next to the running roller, it enables continuous cleaning without stopping the machine, improving production efficiency. The three functions of drive, suction and cleaning are integrated and linked, making the system compact and reliable. Specifically, the cleaning component 5 includes a housing 5.2, inside which is a sponge block 5.1. The liquid suction pipe 4 is connected to the housing 5.2 through multiple connecting pipes 4.1. The cleaning liquid enters the housing 5.2 through the multiple connecting pipes 4.1, ensuring that the sponge block 5.1 is fully and evenly wetted, avoiding local drying that would lead to cleaning failure. The sponge has the ability to absorb and retain liquid, and can continuously release cleaning liquid during the liquid supply interval to maintain a stable wiping effect. The length of the sponge block 5.1 is greater than the length of the roller, and the sponge block 5.1 covers the entire working area of ​​the roller, avoiding edge omissions and ensuring full-width cleaning quality. The sponge block 5.1 has a detachable structure and is fixed inside the housing 5.2 by snaps or magnetic attraction, allowing for quick disassembly for cleaning or replacement of the sponge, reducing downtime and improving maintenance efficiency. Furthermore, the outer wall of the cylinder 3.3 has a slider that slides into the groove of the support frame 2, and a spring is provided in the groove to orient the cylinder 3.3 toward the roll; the spring provides a constant thrust so that the cleaning part 5 is always in close contact with the surface of the roll, and good contact can be maintained even if there is slight radial runout or thermal expansion of the roll. Furthermore, the support plate 1.5 and the support frame 2 are connected by a pin. The support plate 1.5 and the support frame 2 are also connected by a tension spring that keeps the roller 1.1 in contact with the roll. The two ends of the tension spring are respectively connected to the support plate 1.5 and the support frame 2. The tension spring ensures that the roller 1.1 keeps pressing against the roll under various working conditions (such as roll vibration and speed changes), preventing slippage or detachment, ensuring the stable operation of the eccentric drive mechanism, adapting to rolls of different diameters or surface conditions, and enhancing the versatility of the device. Furthermore, the housing 5.2 has an opening on the side near the roller, and flexible scrapers are provided at the top and bottom of the opening edge; the sponge block 5.1 is responsible for dissolving and absorbing stains, and the flexible scrapers further scrape off residual liquid or particles to improve the thoroughness of cleaning; Furthermore, one end of the suction pipe 4 is connected to the storage tank, and a one-way valve is provided near the inlet of the suction pipe 4; the one-way valve ensures that the cleaning liquid can only flow into the suction pipe 4 in one direction, preventing the liquid from flowing back into the storage tank or leaking when the piston 3.4 returns, thus ensuring the stability of the liquid supply and the sealing of the system. In addition, the outer periphery of the roller 1.1 is covered with a wear-resistant rubber layer or a polyurethane layer to ensure reliable rolling transmission between the roller 1.1 and the roll and prevent slippage.
