Description

Technical Field

[0001] This utility model relates to the field of anilox rollers, specifically a ceramic anilox roller that is easy to install and disassemble. Background Technology

[0002] In industrial production fields such as printing and coating, ceramic anilox rollers are a key component. Thanks to the wear-resistant and corrosion-resistant properties of ceramic material, and the advantage of their anilox structure for precisely controlling the transfer of ink or coating, they are widely used in various printing and coating equipment, playing a crucial role in ensuring product quality.

[0003] However, traditional ceramic anilox rollers present numerous inconveniences in actual use, installation, and maintenance. On one hand, the installation and disassembly process is complex and cumbersome. Traditional ceramic anilox rollers are typically one-piece structures or have inconvenient installation and positioning methods. Replacing or repairing the anilox roller sleeve often requires significant time and manpower, sometimes necessitating specialized tools and personnel with specialized skills. This not only increases production costs but also impacts production efficiency. For example, in some large printing companies, production interruptions due to ceramic anilox roller problems can result in economic losses of tens of thousands of yuan per hour.

[0004] On the other hand, there is a lack of effective protective measures. When ceramic anilox rollers are idle, their surfaces are easily damaged by dust, stains, scratches, and other contaminants, which directly affect their lifespan and printing quality. Traditional protective methods are often inadequate and cannot provide comprehensive and effective protection for ceramic anilox rollers. For example, simple plastic film wrapping may not adhere tightly to the roller body, easily falling off and failing to effectively prevent dust from entering; while specialized protective covers may take up considerable space, making storage inconvenient and increasing storage costs for businesses.

[0005] Furthermore, traditional ceramic anilox rollers have a relatively limited function. When the sleeve of the ceramic anilox roller wears out and needs to be removed, the roller body is usually unusable and can only be disposed of as waste, resulting in a waste of resources.

[0019] To make the objectives, technical solutions, and advantages of this utility model clear and complete, the embodiments of this utility model will be further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only some, not all, embodiments of this utility model, and are merely used to explain the embodiments of this utility model. They are not intended to limit the embodiments of this utility model. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0020] Please see Figures 1-4This utility model provides a technical solution: a ceramic anilox roller that is easy to install and disassemble, including a roller body 1, a ceramic anilox roller sleeve 2 sleeved on the outer side of the roller body 1, a limiting component at both ends of the roller body 1, the ceramic anilox roller sleeve 2 being located between the two limiting components, a protective component being embedded in the outer ring of the limiting component, the protective component in the outer ring of the two sets of limiting components being unfolded and sleeved on the ceramic anilox roller sleeve 2, and the ends of the two sets of unfolded protective components being misaligned. In use, before installing the roller body 1, the ceramic anilox roller sleeve 2 is fitted onto the roller body 1. Then, two sets of limiting components are installed at both ends of the roller body 1, and the ceramic anilox roller sleeve 2 is restricted between the two sets of limiting components. The ceramic anilox roller sleeve 2 is fitted onto the outside of the roller body 1. Then, the roller body 1 is installed on the equipment for use. When the ceramic anilox roller sleeve 2 is idle and needs protection, the protective component is pulled out from the outer ring of the limiting component and fitted onto the ceramic anilox roller sleeve 2. The two sets of protective components wrap around and protect the ceramic anilox roller sleeve 2. When the ceramic anilox roller sleeve 2 is removed from the roller body 1, the roller body 1 can be used as a smooth-surface ordinary conveyor roller.

[0021] To achieve the limiting effect of the installation limiting component on the ceramic anilox roller sleeve 2, the following was proposed: The limiting component includes a retaining ring 3 and a connecting screw 5 screwed onto the surface of the retaining ring 3. The retaining ring 3 is sleeved on the end shaft of the roller body 1. The end of the roller body 1 has a screw groove 4 corresponding to the connecting screw 5. The connecting screw 5 passes through the retaining ring 3 and is screwed into the screw groove 4. The outer ring diameter of the retaining ring 3 is smaller than the outer ring diameter of the ceramic anilox roller sleeve 2. An anti-deflection component is provided between the retaining ring 3 and the ceramic anilox roller sleeve 2. The anti-deflection component connects the roller body 1 and the ceramic anilox roller sleeve 2 to rotate synchronously. The anti-deflection component includes multiple inserts 8 fixed on the surface of the retaining ring 3 and slots 7 opened on the end of the ceramic anilox roller sleeve 2 and corresponding to the inserts 8. The inserts 8 and slots 7 match and are inserted into the slots 7. A ring-shaped rubber pad 6 is fixed on the side of the retaining ring 3 near the ceramic anilox roller sleeve 2. The inserts 8 pass through the rubber pad 6 and are fixed on the surface of the retaining ring 3.

[0022] The specific steps for installing the limit component are as follows: After the ceramic anilox roller sleeve 2 is fitted onto the roller body 1, two retaining rings 3 are respectively fitted onto both ends of the roller body 1. Pushing the retaining rings 3 causes the insert 8 to be inserted into the corresponding slot 7. Then, the retaining rings 3 are fixed to the end of the roller body 1 using the connecting screw 5. Since the insert 8 is inserted into the end of the ceramic anilox roller sleeve 2 and the retaining rings 3 are fixed to the end of the roller body 1, the roller body 1 and the ceramic anilox roller sleeve 2 can rotate synchronously after being connected by the retaining rings 3 and the insert 8.

[0023] To facilitate the use and storage of protective components, the following was proposed: The outer ring surface of the retaining ring 3 is provided with a storage groove 9, which is an annular groove. The protective component is stored in the storage groove 9. The protective component includes a rubber cover 10 and an elastic rubber ring 11 fixed to one end of the rubber cover 10. The other end of the rubber cover 10 is fitted and fixed in the storage groove 9. When the rubber cover 10 is unfolded and fitted onto the ceramic anilox roller sleeve 2, the elastic rubber ring 11 is expanded and deformed and fitted onto the ceramic anilox roller sleeve 2. Two plastic baffles 12 are fixed on one side wall of the storage groove 9. After the rubber cover 10 is inserted into the storage groove 9, the plastic baffles 12 block the rubber cover 10 in the storage groove 9. The elastic rubber ring 11 is fitted on the outside of the retaining ring 3.

[0024] When the protective component is not in use, the rubber cover 10 is inserted into the storage groove 9. Due to the limiting effect of the plastic baffle 12, the rubber cover 10 inside the storage groove 9 is prevented from falling out. At this time, the elastic rubber ring 11 is fitted on the outer ring of the retaining ring 3. When the protective component is used, the elastic rubber ring 11 is squeezed by hand, and after the elastic rubber ring 11 is stretched and deformed, the rubber cover 10 is pulled along the ceramic anilox roller sleeve 2. The rubber cover 10 is pulled out from the storage groove 9. After one set of rubber covers 10 is unfolded and fitted on the ceramic anilox roller sleeve 2, another set of rubber covers 10 is also unfolded and fitted on the ceramic anilox roller sleeve 2. The end of the other set of rubber covers 10 and the elastic rubber ring 11 are both fitted on the outside of the end of the first set of rubber covers 10, so that the ends of the two sets of rubber covers 10 are staggered.

[0025] Instructions for using ceramic anilox rollers that are easy to install and remove: Ensure that roller body 1 is 1200mm long, 80mm in outer diameter, and has a smooth, flawless surface. Prepare a ceramic anilox roller sleeve 2 with an inner diameter of 81mm (slightly larger than the outer diameter of roller body 1 for easy fitting), an outer diameter of 120mm, and a length of 1100mm. The anilox pattern specification should be determined according to printing requirements. Prepare two retaining rings 3 with an outer diameter of 100mm, an inner diameter of 81mm (fitting roller body 1), and a thickness of 20mm. Prepare several connecting screws 5, 25mm long and 6mm in diameter, to fit the retaining rings 3 and the screw grooves 4 on roller body 1. Prepare rubber pads 6, 3mm thick, with good elasticity and wear resistance. Prepare inserts 8, 15mm long and 4mm in diameter, to fit the slots 7 on the ceramic anilox roller sleeve 2. Prepare a rubber cover 10, 600mm long and wide enough to completely cover the ceramic anilox roller sleeve 2. The elastic rubber ring 11 has a diameter of 105mm (when not stretched) and good elasticity. Prepare a plastic baffle 12, 10mm long and 5mm wide, to fix the rubber cover 10.

[0026] Slowly slip the ceramic anilox roller sleeve 2 onto the roller body 1, ensuring that there is no scratching or twisting during the slip-on process, so that it is completely slipped onto the outside of the roller body 1, leaving space at both ends for installing the retaining ring 3. Take a retaining ring 3 and slip a rubber pad 6 onto the side of the retaining ring 3 closest to the ceramic anilox roller sleeve 2. Slip the retaining ring 3 with the rubber pad 6 onto one end of the roller body 1, and push the retaining ring 3 so that the insert 8 on the surface of the retaining ring 3 is accurately inserted into the corresponding slot 7 at the end of the ceramic anilox roller sleeve 2, ensuring that the insert 8 and the slot 7 are tightly fitted without any looseness. Use the connecting screw 5, pass it through the retaining ring 3, align it with the corresponding threaded groove 4 at the end of the roller body 1, and use a suitable tool (such as a wrench) to screw the connecting screw 5 into the threaded groove 4, tighten the connecting screw 5, and securely fix the retaining ring 3 to the end of the roller body 1. Following the same method, install another retaining ring 3 at the other end of the roller body 1, ensuring that the two retaining rings 3 are installed symmetrically and that the ceramic anilox roller sleeve 2 is confined between the two retaining rings 3. Check that the two retaining rings 3 are securely installed and that the connecting screws 5 are tightened without any looseness. Rotate the roller body 1 to check that the ceramic anilox roller sleeve 2 can rotate synchronously with the roller body 1 without any deflection or jamming. If any problems are found, adjust the fit between the insert 8 and the slot 7 or reinstall the retaining ring 3.

[0027] Install the assembled ceramic anilox roller onto the printing equipment or other equipment required for its use, ensuring a secure installation and smooth rotation of roller body 1. Adjust the distance and pressure between the ceramic anilox roller and other components (such as impression rollers, ink troughs, etc.) according to equipment requirements. Generally, the distance should be controlled at 0.2-0.5mm (example data, adjust according to actual printing requirements), and the pressure should be adjusted according to the printing material and desired effect. Start the equipment to allow the ceramic anilox roller to begin rotating for printing or other operations. During operation, observe the working status of the ceramic anilox roller, such as the clarity of the anilox pattern and the uniformity of ink transfer. If any abnormalities are found, stop the machine immediately for inspection. Regularly check the wear condition of the ceramic anilox roller sleeve 2, generally every 1000 hours of operation (example data, adjust according to actual usage). If the wear is severe and affects printing quality, replace the ceramic anilox roller sleeve 2 promptly.

[0028] When the ceramic anilox roller is idle and needs protection, locate the rubber cover 10 in the storage groove 9 on the outer ring of the retaining ring 3. Squeeze the elastic rubber ring 11 by hand and gently stretch it to expand and deform it. At the same time, pull the rubber cover 10 along the direction of the ceramic anilox roller sleeve 2, and slowly pull the rubber cover 10 out of the storage groove 9. Unfold the pulled-out set of rubber covers 10 so that it completely covers a part of the ceramic anilox roller sleeve 2. Then, put the elastic rubber ring 11 on the ceramic anilox roller sleeve 2, ensuring that the elastic rubber ring 11 fits tightly against the ceramic anilox roller sleeve 2 without any looseness. In the same way, unfold the other set of rubber covers 10 and put it on the other part of the ceramic anilox roller sleeve 2, so that the end of the other set of rubber covers 10 and the elastic rubber ring 11 are both put on the outside of the end of the first set of rubber covers 10, so that the ends of the two sets of rubber covers 10 are staggered and put on, ensuring that the ceramic anilox roller sleeve 2 is completely wrapped and protected.

[0029] When it is necessary to replace the ceramic anilox roller sleeve 2 or remove it for other uses, first use a suitable tool (such as a wrench) to unscrew the connecting screw 5 from the screw groove 4 and remove the two retaining rings 3. Slowly pull the ceramic anilox roller sleeve 2 off the roller body 1, taking care to avoid scratching the surface of the roller body 1. After removing the ceramic anilox roller sleeve 2, the roller body 1 can be used as a smooth, ordinary conveyor roller. Install it on the corresponding conveying equipment, and adjust the position and tension of the roller body 1 according to the equipment requirements. Generally, the tension is controlled at 50-100N (example data, adjust according to actual conveying requirements) to ensure that the roller body 1 can convey items normally.

[0030] After using the protective components, remove the rubber cover 10 from the ceramic anilox roller sleeve 2. Insert one end of the rubber cover 10 into the storage groove 9, and then slowly insert the entire rubber cover 10 into the storage groove 9, ensuring that the rubber cover 10 is neatly stored in the storage groove 9. Place the elastic rubber ring 11 on the outside of the retaining ring 3, ensuring that the plastic baffle 12 can hold the rubber cover 10 in the storage groove 9, preventing the rubber cover 10 from falling out. By following these detailed usage instructions, the easy-to-install and disassemble ceramic anilox roller can be operated correctly at all stages, extending its service life and improving its efficiency.
