Technical Field

[0001] The utility model relates to the technical field of workpiece processing, in particular to a sizing roller protection mechanism of a corrugated machine. Background Art

[0002] In the production process of corrugated board, the sizing roller is an important part of the corrugator. Its performance stability and service life directly affect the production efficiency and product quality. In the process of using, the traditional sizing roller is often subjected to friction and impact due to the lack of effective protection measures, which leads to accelerated wear and tear, thus affecting production.

[0003] Chinese patent application number CN201420292286.0 discloses a sizing roller protection mechanism of a corrugating machine and a sizing roller thereof, wherein the corrugating machine comprises a sizing roller and a corrugating roller, wherein the sizing roller is composed of a fixed gap convex ring and a sizing roller body, wherein the fixed gap convex ring is arranged at both ends of the sizing roller body and is arranged concentrically with the sizing roller body, and the distance between the fixed gap convex rings at both ends is less than the length of the corrugating roller. The utility model adds fixed gap convex rings at both ends of the sizing roller or the corrugating roller, and when the gap between the sizing roller and the corrugating roller is adjusted too small, the working surfaces of the sizing roller and the corrugating roller are separated by the fixed gap convex ring, thereby avoiding damage to the sizing surface of the sizing roller and improving the service life of the sizing roller and the corrugating roller. The fixed gap convex rings in the sizing roller protection mechanism of the corrugating machine are arranged at both ends of the sizing roller body, and the fixing effect is unstable, and long-term use will also cause wear, which is very inconvenient to replace and increases the workload of the operator.

[0029] The protection mechanism of the sizing roller of the corrugator, such as Figure 1-Figure 3As shown, it includes a sizing roller 10, and replaceable protective convex rings 20 are installed at both ends of the sizing roller 10. The replaceable protective convex rings 20 at both ends are connected to the ends of the sizing roller 10 through at least three sets of fixing bolts 30 respectively; one end of the replaceable protective convex ring 20 is coaxially provided with a plug-in groove 21 that is adapted to the outer diameter of the sizing roller 10 and is interference-fitted, and the end of the replaceable protective convex ring 20 is provided with a fixing hole 24 that is the same in number, corresponding in position, and adapted in size as the fixing bolts 30. Through the provided replaceable protective convex ring 20, the sizing roller 10 is effectively protected during use. Since the replaceable protective convex ring 20 is made of wear-resistant and high-strength material, it can effectively reduce the friction and impact of the sizing roller 10 during operation, and prolong the service life of the sizing roller 10. The replaceable protective convex ring 20 is connected to the sizing roller 10 by interference-fitting, so that the connection between the two is tight and reliable, and not easy to loosen or fall off. At the same time, the fixation by at least three sets of fixing bolts 30 not only enhances the stability and safety of the connection, but also facilitates installation or disassembly, thereby reducing maintenance costs and time costs.

[0030] Furthermore, a rotating shaft 11 is coaxially installed at both ends of the sizing roller 10, and a plug-in hole 23 that is compatible with the size of the rotating shaft 11 and is plug-matched is coaxially opened on the replaceable protective convex ring 20. By setting the rotating shaft 11 and the plug-in hole 23, the replaceable protective convex ring 20 can be more stably installed on the sizing roller 10. The cooperation between the rotating shaft 11 and the plug-in hole 23 increases the connection strength between the two, prevents the protective convex ring from shifting or falling off during operation, and further improves the stability and durability of the sizing roller.

[0031] Specifically, the outer walls of both ends of the sizing roller 10 are provided with limit grooves 13, and the inner wall of the plug-in slot 21 is provided with limit strips 22 that are adapted to the size of the limit grooves 13 and are snap-fitted. The limit grooves 13 and the limit strips 22 are provided, so that the connection between the replaceable protective convex ring 20 and the sizing roller 10 is tighter and more precise. The limit strips 22 can be snapped into the limit grooves 13, effectively preventing the protective convex ring from rotating or shaking during operation, and further enhancing the stability and reliability of the protective mechanism.

[0032] Among them, the outer walls at both ends of the sizing roller 10 are provided with an anti-slip layer 12, which is made of silicone material and has a thickness of 1-3mm. The anti-slip layer 12 made of silicone material has excellent anti-slip performance and can increase the friction between the sizing roller and the protective convex ring to prevent the two from sliding or separating during high-speed operation.

[0033] In addition, a wear-resistant outer layer 25 is installed on the outer wall of the replaceable protective convex ring 20. The wear-resistant outer layer 25 is made of PU polyurethane, rubber or silicon carbide, and has a thickness of 2-5mm. It has excellent wear resistance and impact resistance, can effectively resist friction and collision during work, and protect the sizing roller from damage.

[0034] The working principle of the sizing roller protection mechanism of the corrugating machine is as follows: the operator aligns one end of the replaceable protective convex ring 20 with the end of the sizing roller 10, ensures that the plug-in groove 21 matches the outer diameter of the sizing roller 10, uses appropriate force to push the replaceable protective convex ring 20 to the end of the sizing roller 10 to achieve an interference fit, aligns the fixing bolts 30 with the fixing holes 24 on the replaceable protective convex ring 20, ensures that the quantity, position and size match, uses tools such as a screwdriver or a wrench to screw the fixing bolts 30 into the fixing holes 24, and tightens them to an appropriate force to ensure a firm connection.

[0035] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only preferred examples of the utility model and are not used to limit the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected.
