Abstract

This utility model relates to the field of anilox roller technology, specifically a positioning mechanism and a ceramic anilox roller. It includes a stud installed at the end of the roller body. A ceramic anilox roller sleeve is fitted onto the shaft of the roller body. The stud penetrates the end plate of the ceramic anilox roller sleeve, and a nut is screwed onto the end of the stud away from the roller body. A pre-reserved groove is formed at the end of the roller body away from the stud, and a hand-tightening screw is screwed onto the outer ring surface of the groove. One end of the hand-tightening screw is screwed onto the inner ring surface of the ceramic anilox roller sleeve. The beneficial effect is that when the outer surface of the ceramic anilox roller sleeve is severely worn, because this positioning mechanism uses a detachable connection method such as the stud, nut, and hand-tightening screw, the ceramic anilox roller sleeve can be easily removed from the roller body simply by unscrewing the nut and hand-tightening screw in sequence. Then, a new ceramic anilox roller sleeve can be installed and reinstalled. This design avoids the need to replace the entire roller body due to wear of the ceramic anilox roller sleeve, greatly reducing production costs.

Description

Technical Field

[0001] This utility model relates to the field of anilox rollers, specifically a positioning mechanism and a ceramic anilox roller. Background Technology

[0002] In relevant industrial production and processing fields, roller structures with specific functions are often required. Traditional roller structures often have relatively simple functions, such as some ordinary pressure rollers or conveyor rollers, which can only realize simple transmission or conveying functions.

[0003] In certain process scenarios, such as printing and coating, a specific anilox structure needs to be formed on the roller surface to achieve uniform ink or coating transfer. If an integral anilox roller is used, when the anilox portion on the roller surface wears out severely due to long-term use, the entire roller often needs to be replaced. This not only wastes materials but also increases production costs and downtime. Furthermore, existing roller structures with replaceable anilox sleeves suffer from insufficient connection stability, leading to issues such as loosening and displacement of the anilox sleeve during use, affecting process stability and product quality.

[0004] Therefore, developing a positioning mechanism that can both facilitate the replacement of the mesh sleeve and ensure a stable and reliable connection is of great practical significance. Utility Model Content

[0005] The purpose of this invention is to provide a positioning mechanism and a ceramic anilox roller to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a positioning mechanism, including a stud, which is installed at the end of a roller body. A ceramic anilox roller sleeve is fitted on the shaft of the roller body. The stud penetrates the end plate of the ceramic anilox roller sleeve, and a nut is screwed onto the end of the stud away from the roller body. A reserved groove is provided at the end of the roller body away from the stud. A hand-tightening screw is screwed onto the outer ring surface of the reserved groove, and one end of the hand-tightening screw is screwed onto the inner ring surface of the ceramic anilox roller sleeve.

[0007] Preferably, the end plate of the ceramic anilox roller sleeve is provided with multiple mounting grooves, and the surface of the mounting groove is provided with a through hole. The ceramic anilox roller sleeve and the through hole correspond one-to-one. The ceramic anilox roller sleeve is inserted into the through hole, and the end of the ceramic anilox roller sleeve and the nut are both in the mounting groove.

[0008] Preferably, a rubber pad is fixed to one end of the roller body. The rubber pad has an annular plate structure, and there are two rubber pads with different sizes. The rubber pad is sandwiched between the roller body and the ceramic anilox roller sleeve.

[0009] Preferably, the reserved slots are provided in multiple ways, and each reserved slot has a second through hole on its outer ring surface. The inner ring surface of the ceramic anilox roller sleeve has a screw groove, and the hand-tightened screw passes through the second through hole and is screwed into the screw groove.

[0010] Preferably, a rubber sealing plate is fixed to the inner ring surface of the reserved groove, and one side of the rubber sealing plate abuts against the outer ring surface of the reserved groove, thereby sealing the opening of the reserved groove.

[0011] A ceramic anilox roller includes a ceramic anilox roller sleeve, which is mounted on the roller body via a positioning mechanism.

[0012] Compared with the prior art, the beneficial effects of this utility model are: The positioning mechanism and ceramic anilox roller proposed in this utility model allow for easy removal of the ceramic anilox roller sleeve from the roller body when the outer surface of the sleeve is severely worn. This is because the positioning mechanism uses a detachable connection method involving studs, nuts, and hand-tightening screws. Simply unscrew the nut and hand-tightening screw in sequence, and then replace it with a new ceramic anilox roller sleeve and reinstall it. This design avoids the need to replace the entire roller body due to wear of the ceramic anilox roller sleeve, significantly reducing production costs, minimizing downtime, and improving production efficiency.

[0013] If the ceramic anilox roller sleeve is not needed, it can be removed from the roller body. At this time, the roller body can be used as a transmission pressure roller or conveyor roller, which increases the versatility and flexibility of the equipment, allowing the same equipment to adapt to different production needs and improve the utilization rate of the equipment.

[0014] A stud is inserted through the end plate of the ceramic anilox roller sleeve and a nut is fitted onto it, ensuring that both the end of the ceramic anilox roller sleeve and the nut are in the mounting groove, thus achieving initial positioning and connection. Simultaneously, a rubber pad is placed at one end of the roller body. When the nut is tightened, the ceramic anilox roller sleeve compresses and deforms the rubber pad, which then springs back to support the ceramic anilox roller sleeve, further enhancing the stability of the connection.

[0017] 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.

[0018] Example 1, please refer to Figures 1-6 This utility model provides a technical solution: a positioning mechanism, including a stud 1, which is installed at the end of a roller body 2. A ceramic anilox roller sleeve 3 is sleeved on the shaft of the roller body 2. The stud 1 penetrates the end plate of the ceramic anilox roller sleeve 3, and a nut 6 is screwed onto the end of the stud 1 away from the roller body 2. Multiple mounting grooves 5 are opened on the end plate of the ceramic anilox roller sleeve 3, and through holes 4 are opened on the surface of the mounting grooves 5. The ceramic anilox roller sleeve 3 and the through holes 4 correspond one-to-one. The ceramic anilox roller sleeve 3 is inserted into the through holes 4, and the end of the ceramic anilox roller sleeve 3 and the nut 6 are both in the mounting grooves 5. A rubber pad 7 is fixed at one end of the roller body 2. The rubber pad 7 has an annular plate structure, and there are two rubber pads 7 with different sizes. The rubber pad 7 is sandwiched between the roller body 2 and the ceramic anilox roller sleeve 3. In use, the ceramic anilox roller sleeve 3 is fitted onto the roller body 2. At this time, the stud 1 passes through the through hole 4 and the mounting groove 5. After the nut 6 is screwed onto the corresponding stud 1, the nut 6 and the stud 1 are tightened. At this time, the ceramic anilox roller sleeve 3 compresses the rubber pad 7 and deforms. The rubber pad 7 rebounds and supports the ceramic anilox roller sleeve 3, making the stud 1 and the nut 6 securely connected. When the outer surface of the ceramic anilox roller sleeve 3 is severely worn, the ceramic anilox roller sleeve 3 can be removed and replaced separately. If the ceramic anilox roller sleeve 3 is not needed, it can be removed from the roller body 2, and the roller body 2 can be used as a pressure roller or a conveyor roller for transmission.

[0019] A reserved groove 8 is provided at the end of the roller body 2 away from the stud 1. A hand-tightening screw 11 is screwed onto the outer ring surface of the reserved groove 8. One end of the hand-tightening screw 11 is screwed onto the inner ring surface of the ceramic anilox roller sleeve 3. There are multiple reserved grooves 8. Each reserved groove 8 has a through hole 9 on its outer ring surface. A screw groove 10 is provided on the inner ring surface of the ceramic anilox roller sleeve 3. The hand-tightening screw 11 passes through the through hole 9 and is screwed into the screw groove 10. A rubber sealing piece 12 is fixed on the inner ring surface of the reserved groove 8. One side of the rubber sealing piece 12 abuts against the outer ring surface of the reserved groove 8, and the rubber sealing piece 12 seals the opening of the reserved groove 8. When in use, after the ceramic anilox roller sleeve 3 is fitted onto the roller body 2 and the stud 1 and nut 6 are screwed together, the rubber sealing plate 12 is lifted, and the hand-tightening screw 11 is inserted into the through hole 9 from the reserved groove 8. The hand-tightening screw 11 is screwed into the screw groove 10 to strengthen the connection between the end of the ceramic anilox roller sleeve 3 and the roller body 2.

[0020] Positioning mechanism usage: Place the ceramic anilox roller sleeve 3 onto the roller body 2, ensuring that the stud 1 passes through the through hole 4 and mounting groove 5 on the end plate of the ceramic anilox roller sleeve 3. Screw the nut 6 onto the corresponding stud 1, tightening the nut 6 and stud 1. At this time, the ceramic anilox roller sleeve 3 compresses the rubber pad 7, causing it to deform. The rubber pad 7 rebounds and supports the ceramic anilox roller sleeve 3, making the stud 1 and nut 6 firmly connected. After completing the screwing connection of the stud 1 and nut 6, lift the rubber sealing plate 12 fixed to the inner ring surface of the reserved groove 8. One side of the rubber sealing plate 12, which was originally against the outer ring surface of the reserved groove 8, is now exposed, revealing the reserved groove 8 and related structures. Insert the hand-tightening screw 11 into the pre-reserved slot 8 and through hole 9 (there are multiple pre-reserved slots 8, each with through hole 9 on the outer ring surface). Then, tighten the hand-tightening screw 11 so that it is screwed into the threaded groove 10 on the inner ring surface of the ceramic anilox roller sleeve 3, thereby reinforcing the connection between the end of the ceramic anilox roller sleeve 3 and the roller body 2. After installing the hand-tightening screw 11, return the rubber sealing piece 12 to its original position to seal the opening of the pre-reserved slot 8. When the outer surface of the ceramic anilox roller sleeve 3 is severely worn, first unscrew the hand-tightening screw 11, then unscrew the nut 6, remove the ceramic anilox roller sleeve 3 from the roller body 2, and then replace it with a new ceramic anilox roller sleeve 3, reinstalling it according to the above installation steps. If the ceramic anilox roller sleeve 3 is not needed, similarly, first unscrew the hand-tightening screw 11, then unscrew the nut 6, remove the ceramic anilox roller sleeve 3 from the roller body 2. At this time, the roller body 2 can be used as a transmission pressure roller or conveyor roller.

[0021] Example 2, based on Example 1, proposes a ceramic anilox roller, including a ceramic anilox roller sleeve 3, which is mounted on the roller body 2 by a positioning mechanism.

[0022] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
