Description

An embossing steel roller used in paper towel processing equipment

technical field

The utility model relates to the technical field of paper towel processing equipment, in particular to an embossed steel roller used in paper towel processing equipment.

Background technique

It is well known in the industry that the embossed steel rollers used in traditional paper towel processing equipment are generally engraved with their own decorative patterns on the roller surface. When working, the embossing device generally adopts a smooth roller and an embossing roller, or a double-roller embossing structure of two embossing rollers. The processed paper towel passes through the gap between the two rollers to complete the embossing process. Although the embossing device of this design can press the desired pattern, because the embossing device generally adopts the method of pressing on both sides, and In actual work, it is difficult to achieve simultaneous pressurization on both sides, which will cause uneven linear pressure on the embossing roller surface and affect the embossing depth, especially when the double rollers used in the embossing device are steel rollers, and the two When the length or diameter of the root steel roll is relatively large, it will be more difficult to adjust the linear pressure on the steel roll surface, and it is easy to crush the engraved patterns on the roll surface, which will affect the product quality. At the same time, it is necessary to repair the damaged embossing Steel rolls need to be replaced, increasing production costs.

Utility model content

The purpose of the utility model is to overcome the deficiencies of the prior art, and provide an embossed steel roller used in paper towel processing equipment with reasonable design, reliability and durability.

In order to achieve the above purpose, the technical solution provided by the utility model is: an embossed steel roll used in paper towel processing equipment, the two ends of the roll surface of the embossed steel roll are provided with supporting surfaces to limit the depth of embossing.

The height of the supporting surface is slightly higher than half of the height of the protrusions of the pattern pattern.

The height of the supporting surface is equal to or slightly higher than the height of the protrusions of the pattern pattern.

The supporting surface is a smooth roller surface or a concave-convex surface or a textured surface.

After the utility model adopts the above-mentioned scheme, its biggest advantage is that because the utility model is provided with supporting surfaces that limit the depth of embossing at both ends of the roller surface, the pressure on the supporting surfaces at both ends is the largest during work, thereby reducing the embossing depth. The pressure on the pattern pattern can play a very good limit protection effect on the pattern pattern, preventing the pattern pattern from being crushed during embossing. At the same time, the height of the supporting surface of the utility model can be adjusted according to the depth of embossing and the size of the pressure. Adjust to meet actual work needs.

Detailed ways

The utility model will be further described below in conjunction with a plurality of specific embodiments.

Embodiment 1: According to the accompanying drawings 1 and 2, this embodiment is an embossing device that adopts double embossing steel rollers placed on the frame 4 in sequence up and down to form a double-roller embossing, and the described Each embossed steel roll is provided with a support surface 1 at both ends of the roll surface to limit the embossing depth. At the same time, the support surface 1 is a smooth roll surface, and of course it can also be a concave-convex surface or a textured surface, and the support surface 1 The height of the surface 1 is equal to or slightly higher than the height of the protrusions 2 of the pattern pattern. When working, the pressure is transmitted through the pressing rods 5 at both ends of the embossing steel roller on the frame 4, so that it is pressed to the raw paper to be processed passing through the gap between the two rollers, and the embossing process is completed, although during this process, the embossing It is difficult for the pressing rods 5 at both ends of the steel roll to achieve synchronous pressurization, but since the two ends of the embossed steel roll surface of this embodiment are provided with a supporting surface 1 that limits the embossing depth, the supporting surface 1 bears Most of the pressure during embossing, so that even if the line pressure during embossing is uneven, the pattern will not be crushed, and it plays a good role in limiting the pattern.

Embodiment 2: As shown in accompanying drawings 3 and 4, the difference from embodiment 1 is that the height of the supporting surface 1 at both ends of the embossing steel roll surface of this embodiment is slightly higher than the height of the pattern pattern protrusions 2 Half, when working, the desired embossing pattern effect is completed by the mutual toothing between the pattern pattern protrusions 2 on the two embossing steel rollers described in this embodiment. Both ends of the flower steel roll surface are provided with a supporting surface 1 that limits the depth of embossing, and most of the pressure during embossing is borne by this supporting surface 1, so that even if the line pressure during embossing is uneven, it will not Crush the pattern and play a very good limit protection for the pattern.

Embodiment 3: According to the accompanying drawing 5, the difference from Embodiment 1 is that the embossing device described in this embodiment uses an embossing steel roller and a smooth steel roller 3 placed on the frame in sequence 4 to form a double-roller embossing structure, and the supporting surface 1 at both ends of the embossing steel roll surface can only be a smooth roll surface; when working, press the embossing steel roll to the smooth steel roll 3 to process the base paper Embossing, to complete the required embossing pattern effect, similarly, since the two ends of the embossing steel roll surface of this embodiment are provided with a supporting surface 1 that limits the embossing depth, when the embossing is carried by the supporting surface 1 Most of the pressure, so that even if the line pressure is uneven during embossing, the pattern will not be crushed, and it plays a very good limit protection for the pattern.

The above-described embodiments are only preferred embodiments of the present utility model, and are not intended to limit the scope of implementation of the present utility model, so all changes made according to the shape and principle of the present utility model should be covered by the scope of the present utility model. within the scope of protection.
