Description

Technical Field

[0001] This utility model relates to the technical field of anilox roller assemblies, specifically an anilox roller cover. Background Technology

[0002] Anilox rollers are indispensable key components in modern printing and coating processes. Their main function is to uniformly and accurately transfer fluid materials to the surface of the substrate, while controlling the amount of material used, thereby improving production efficiency and product quality. However, in actual anilox roller printing or coating processes, the flowing material may overflow from the outer periphery of the rods at both ends of the anilox roller. As the anilox roller rotates at high speed, the fluid material overflowing to both ends of the anilox roller will splash onto the printed parts under the action of centrifugal force. Therefore, an anilox roller cover is installed on the outer periphery of the anilox roller to prevent ink splashing and to recover some of the overflowing ink.

[0003] Most current anilox roller covers are structured as described in the text of Chinese Patent Publication No. CN217550248U entitled "An Anilox Roller". They employ anti-splash ring covers fixed to the outer periphery of both ends of the anilox roller, and collect printing adhesive in the anti-splash ring covers by fixing adhesive collection ring boxes to the ends of the anilox roller.

[0004] In practical implementation, the anti-splatter ring structure fixed to the anilox roller as described in the cited patent has the following problems: First, since printing or coating operations are often continuous for long periods, the fixed connection between the anti-splatter ring and the anilox roller means that the anti-splatter ring rotates synchronously with the anilox roller during operation. Therefore, fluid material centrifugally thrown to the inner wall of the anti-splatter ring will adhere to the inner wall of the anti-splatter ring under centrifugal force and continue to rotate with the anti-splatter ring. Obviously, during long periods of continuous operation, the fluid material may become fully loaded inside the anti-splatter ring and overflow onto the printed material in the middle of the anilox roller. Inevitably, the operation of the anilox roller needs to be stopped at this point so that the fluid material can be collected inwards into the collection ring box under gravity. Furthermore, the fluid material in the collection ring box needs to be drained to prevent it from centrifugally flowing back into the anti-splatter ring when restarting, severely affecting the continuous operation of printing or coating. Secondly, due to the structure of the aforementioned anti-splash ring, the fluid material will adhere tightly to the inner wall of the anti-splash ring under the action of centrifugal force. To prevent insufficient sealing at the break point of the anti-splash ring caused by the split structure, the traditional anti-splash ring and glue collection ring box are often designed as an integrated ring structure. This integrated structure design requires the end of the anilox roller to be removed from the frame before the new anti-splash ring and glue collection ring box can be installed when the anti-splash ring and glue collection ring box need to be repaired or replaced. Obviously, this also has the problem of poor disassembly and assembly convenience, which urgently needs to be solved. Utility Model Content

[0005] In order to avoid and overcome the technical problems existing in the prior art, this utility model provides an anilox roller cover, which is not only easy to disassemble and maintain, but also can continuously discharge the fluid material inside the anilox roller cover, preventing the fluid material from accumulating inside the anilox roller cover and overflowing again.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] An anilox roller cover includes a lower half-ring and two lower half-stop rings fixed at both ends of the lower half-ring, which together form a lower semi-circular groove. The bottom of the lower semi-circular groove is connected to a discharge pipe for discharging material from its cavity. The lower semi-circular groove is fixed to a frame by a mounting cantilever. The groove end of the lower semi-circular groove extends vertically upward in the circumferential direction to form a vertical extension end. The cover also includes an upper half-ring and upper half-stop rings fixed at both ends of the upper half-ring, which together form an upper semi-circular groove. The outer edges of both ends of the upper semi-circular groove are vertically arranged and interlock with the vertical insertion end. The semi-cylindrical surfaces formed by the bottom contours of the upper and lower semi-circular grooves are coaxially arranged with the anilox roller, and there is a gap between the groove openings of the upper and lower semi-circular grooves and the outer edge of the anilox roller for the passage of fluid material.

[0008] As a further embodiment of this utility model: the outer edges of both ends of the lower and upper semicircular grooves in the circumferential direction are respectively fixed with a sliding buckle and an upper sliding buckle. The upper and lower sliding buckles slide and engage along the axial direction of the anilox roller to prevent the lower and upper semicircular grooves from separating radially along the anilox roller. In addition, along the axial direction of the anilox roller, there is a widened space between the inner cavity of the lower semicircular groove and the side wall of the lower semicircular groove to avoid misalignment before the upper and lower sliding buckles slide and engage.

[0009] As a further embodiment of this utility model: the cross-sectional outline of the sliding buckle is T-shaped, and the inner side of the upper sliding buckle has a groove-shaped outline that matches the T-shaped structure. The sliding snap is formed by the sliding block of the T-shaped structure and the snap-fit ​​groove.

[0010] As a further improvement of this utility model: a locking rod is arranged on the mounting cantilever, and both the upper sliding buckle and the lower sliding buckle have insertion holes arranged with the hole length direction perpendicular to their sliding direction. In the sliding engagement state, the insertion holes of the two are aligned and both are inserted by the locking rod to form a sliding locking state of the upper sliding buckle and the lower sliding buckle. In the sliding locking state, the locking rod and the mounting cantilever are assembled on the frame by fixing screws that pass through them.

[0011] As a further improvement of this utility model: the mounting cantilever is provided with a sliding groove arranged along the sliding direction of the locking rod in the groove length direction, and the locking rod slides and engages in the sliding groove.

[0012] As a further embodiment of this utility model: both outer edges of the lower semicircular groove are fixedly connected to positioning plates. When the lower semicircular groove and the upper semicircular groove are inserted and assembled, the groove end of the upper semicircular groove abuts against the positioning plate in the circumferential direction to position the vertical installation position of the upper semicircular groove. At this time, the upper sliding buckle and the lower sliding buckle are aligned along their sliding engagement direction.

[0013] As a further embodiment of this utility model: the area directly below the width of the upper semicircular groove along the axial direction of the anilox roller is the anti-splash area, and the end of the anilox roller is located inside the anti-splash area.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. This application abandons the traditional one-piece annular structure of the anilox roller cover, which is fixed to the anilox roller. Instead, the anilox roller cover is a two-section structure assembled from an upper and lower semi-circular groove. This eliminates the need to disassemble the anilox roller during assembly and disassembly, improving the ease of assembly and disassembly. Furthermore, the anilox roller cover is fixed to the frame by a cantilever. Both the upper and lower semi-circular grooves have gaps between their openings and the outer edge of the anilox roller to allow fluid material to pass through, thus forming a separate design between the anilox roller cover and the anilox roller. This separate design does not obstruct fluid material from overflowing to the end and also achieves good splash prevention and recovery of fluid material ejected from the anilox roller.

[0016] Furthermore, the way the anilox roller cover, composed of the upper and lower semicircular grooves, is fixed to the frame ensures that it does not rotate synchronously with the anilox roller during its rotation. Therefore, any fluid material splashed into either the lower or upper semicircular groove cavity will flow downwards under gravity. Thus, even with the convenient plug-in assembly where the lower semicircular groove is on the outside and the upper semicircular groove is on the inside, the flowing material cannot flow upwards through the joint, effectively preventing overflow from the joint. Subsequently, the downward-flowing fluid material can be continuously and continuously discharged in real time through the discharge pipe at the bottom of the lower semicircular groove, effectively preventing overflow from the anilox roller cover cavity when it is full.

[0017] 2. Sliding buckles and upper sliding buckles are fixed to the outer edges of both ends of the lower and upper semicircular grooves in the circumferential direction, respectively. The upper and lower sliding buckles slide and engage along the axial direction of the anilox roller to prevent the lower and upper semicircular grooves from separating radially along the anilox roller. Therefore, under the condition that the lower and upper semicircular grooves are subjected to radial centrifugal force from the inside out by the fluid material, the sliding engagement of the lower and upper sliding buckles prevents the semicircular grooves from separating radially along the anilox roller, significantly improving the stability of the upper and lower semicircular grooves under the insertion assembly.

[0018] 3. The mounting arm is equipped with a locking rod. Both the upper and lower sliding buckles have insertion holes with the length direction of the hole perpendicular to their sliding direction. In the sliding engagement state, the insertion holes of the two buckles are aligned and both are inserted by the locking rod to form a sliding lock state of the upper and lower sliding buckles. In the sliding lock state, the locking rod and the mounting arm are assembled on the frame by fixing screws that pass through them.

[0019] This structural arrangement not only further prevents the lower sliding buckle and upper sliding buckle from sliding apart in the sliding snap-fit ​​state, but also allows the locking rod to be fixed on the frame during the installation of the cantilever using fixing screws, eliminating the need for additional fixing structures and reducing the difficulty of fixing the locking rod.

[0020] 4. Positioning plates are fixedly connected to both outer edges of the lower semicircular groove in the circumferential direction. When the lower and upper semicircular grooves are inserted and assembled, the groove end of the upper semicircular groove in the circumferential direction abuts against the positioning plate, thereby accurately positioning the installation position of the upper semicircular groove in the vertical direction. At this time, the upper sliding buckle and the lower sliding buckle are aligned along their sliding engagement direction to facilitate quick sliding engagement between the upper sliding buckle and the lower sliding buckle.

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] For ease of understanding, the specific structure and working method of this utility model are further described below with reference to the accompanying drawings:

[0030] The specific structure of this utility model is as follows: Figure 1-6 As shown, its main structure includes a lower half ring 10 and two lower half retaining rings 11 fixed at both ends of the lower half ring 10, which together form a lower semicircular groove; it also includes an upper half ring 20 and upper half retaining rings 21 fixed at both ends of the upper half ring 20, which together form an upper semicircular groove.

[0031] Among them, such as Figure 1 and Figure 2 As shown, the lower semicircular groove extends vertically upwards from its circumferential end to form a vertical extension end. The outer edges of both ends of the upper semicircular groove are vertically arranged and interlock with the vertical insertion end. This results in a two-section structure for the anilox roller cover, consisting of the upper and lower semicircular grooves. This allows for easy assembly and disassembly of the anilox roller cover without disassembling the anilox roller itself. Furthermore, the lower semicircular groove is fixed to the frame by a cantilever 30. The semi-cylindrical surfaces formed by the bottom contours of both the upper and lower semicircular grooves are coaxially arranged with the anilox roller. Both the groove openings of the upper and lower semicircular grooves have gaps between them and the outer edge of the anilox roller for fluid material to pass through, thus creating a separate design between the anilox roller cover and the anilox roller. This separate design does not obstruct fluid material from overflowing to the end and also achieves good splash prevention and recovery of fluid material ejected from the anilox roller.

[0032] Furthermore, the way the anilox roller cover, composed of the upper and lower semicircular grooves, is fixed to the frame ensures that it does not rotate synchronously with the anilox roller during its rotation. Therefore, any fluid material splashed into either the lower or upper semicircular groove cavity will flow downwards under gravity. Thus, even with the convenient plug-in assembly where the lower semicircular groove is on the outside and the upper semicircular groove is on the inside, the flowing material cannot flow upwards through the joint, effectively preventing overflow from the joint. Subsequently, the downward-flowing fluid material can be continuously and continuously discharged in real time through the discharge pipe 60 at the bottom of the lower semicircular groove, effectively preventing overflow of fluid material from the anilox roller cover cavity when it is full.

[0033] Based on the above, such as Figure 2 As shown, the outer edges of both ends of the lower and upper semicircular grooves in the circumferential direction are respectively fixed with sliding buckles 12 and upper sliding buckles 22; as Figure 1 and Figure 4 As shown, the upper sliding buckle 12 and the lower sliding buckle 22 slide and engage along the axial direction of the anilox roller to prevent the lower semicircular groove and the upper semicircular groove from separating radially along the anilox roller. Along the axial direction of the anilox roller, there is a widened space between the inner cavity of the lower semicircular groove and the side wall of the lower semicircular groove to avoid misalignment before the upper sliding buckle 12 and the lower sliding buckle 22 slide and engage.

[0034] During installation, before inserting the upper semicircular groove into the lower semicircular groove cavity, the space is widened to ensure that the sliding buckle 12 and the upper sliding buckle 22 avoid each other in a vertical view. After the upper semicircular groove is inserted into the lower semicircular groove, the two are slid along the axial direction of the anilox roller, causing the sliding buckle 12 and the upper sliding buckle 22 to engage. Under the condition that the upper and lower semicircular grooves are subjected to radial centrifugal force from the inside out by the fluid material, the sliding engagement of the sliding buckle 12 and the upper sliding buckle 22 prevents the semicircular grooves from separating radially along the anilox roller, significantly improving the stability of the upper and lower semicircular grooves during assembly.

[0035] Specifically, the cross-sectional outline of the sliding buckle 12 is T-shaped, and the inner side of the upper sliding buckle 22 has a groove-shaped outline that matches the T-shaped structure. The sliding engagement is formed by the sliding block of the T-shaped structure and the groove. Obviously, at this time, the upper sliding buckle 12 and the lower sliding buckle 22 can only slide along the axial direction of the anilox roller.

[0036] Of course, the T-shaped cross-sectional profile of the aforementioned sliding buckle 12 is only one embodiment provided in this application. In actual implementation, the cross-sectional profile of the sliding buckle 12 can be circular, triangular, or other irregular structures. At the same time, the snap-fit ​​groove is adapted to the cross-sectional profile of the sliding buckle 12, so that when the two are slidably snapped together, the upper sliding buckle 12 and the lower sliding buckle 22 can only slide along the axial direction of the anilox roller.

[0037] Of course, in actual implementation, the above-described implementation of the sliding buckle 12 and upper sliding buckle 22 is mainly applicable when the weight of the upper semicircular groove is small or the friction at the insertion joint of the upper and lower semicircular grooves is small. When the weight of the upper semicircular groove is large enough, or the friction at the insertion joint of the upper and lower semicircular grooves is large enough, stable insertion joint assembly can be achieved without the upper sliding buckle 12 and lower sliding buckle 22. Of course, if the actual installation space is insufficient, a counterweight can be set on the upper semicircular groove or a material with greater weight can be used for the upper semicircular groove.

[0038] Based on the above, to further prevent the lower sliding buckle 12 and the upper sliding buckle 22 from sliding apart in the sliding engagement state, such as Figure 1 and Figure 2 As shown, a locking rod 40 is arranged on the mounting arm 30. Both the upper sliding buckle 12 and the lower sliding buckle 22 have insertion holes with the length direction of the hole perpendicular to their sliding direction. In the sliding engagement state, the insertion holes of the two are aligned and both are inserted by the locking rod 40 to form a sliding lock state of the upper sliding buckle 12 and the lower sliding buckle 22. In the sliding lock state, the locking rod 40 and the mounting arm 30 are assembled on the frame by fixing screws 50 that pass through them.

[0039] This structural arrangement, by inserting the locking rod 40 perpendicularly to the sliding direction of the lower sliding buckle 12 and the upper sliding buckle 22 into their respective insertion holes, prevents the lower sliding buckle 12 and the upper sliding buckle 22 from sliding relative to each other, thus achieving sliding locking. Furthermore, the locking rod 40 can be fixed to the cantilever 30 on the frame using the fixing screw 50, eliminating the need for additional fixing structures and reducing the difficulty of fixing the locking rod 40.

[0040] Furthermore, such as Figure 1 and Figure 4 As shown, the mounting cantilever 30 is provided with a sliding groove 31 arranged along the sliding direction of the locking rod 40 in the longitudinal direction of the groove. The locking rod 40 is slidably engaged in the sliding groove 31. By guiding the sliding of the locking rod 40 through the sliding groove 31, the precise alignment of the locking rod 40 with the insertion hole can be ensured, improving the convenience of the locking rod 40 insertion process.

[0041] Furthermore, such as Figure 1 and Figure 4 As shown, positioning plates 13 are fixedly connected to both outer edges of the lower semicircular groove in the circumferential direction. When the lower semicircular groove and the upper semicircular groove are inserted and assembled, the groove end of the upper semicircular groove in the circumferential direction abuts against the positioning plate 13, thereby accurately positioning the installation position of the upper semicircular groove in the vertical direction. At this time, the upper sliding buckle 22 and the lower sliding buckle 12 are aligned along their sliding engagement direction, so as to achieve quick sliding engagement between the upper sliding buckle 22 and the lower sliding buckle 12.

[0042] The assembly position of the anilox roller cover, consisting of an upper and lower semicircular groove, requires attention to the following: the area directly below the groove width of the upper semicircular groove along the axial direction of the anilox roller is the splash-proof area. The end of the anilox roller (excluding the shaft connecting the anilox roller and the frame) is located inside the splash-proof area, ensuring that the splash-proof area includes the very end of the anilox roller, thus guaranteeing comprehensive splash prevention and recovery of any fluid material overflowing from the anilox roller. Of course, in actual assembly, the side of the splash-proof area closer to the middle of the anilox roller is located at the point where the fluid material overflows between the anilox roller and the printed material. Further details regarding existing technologies are omitted here.

[0043] Of course, those skilled in the art will recognize that this invention is not limited to the details of the exemplary embodiments described above, but also includes the same or similar structures that can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description.
