Description

Technical Field

[0001] The utility model relates to the technical field of production and processing of wide-width disposable sanitary products such as nursing pads, and in particular to a pressure roller device capable of automatically detecting winding. Background Art

[0002] Common disposable nursing pad sanitary products have a surface covered with hydrophilic non-woven fabric, a bottom layer of PE film, and an absorbent between the surface and bottom layers. The absorbent is composed of upper and lower layers of toilet paper wrapped in wood pulp fibers. The surface of the absorbent (toilet paper) must be pressed into patterns of various shapes by a pressing roller mechanism. The pattern can fix the absorbent, divert liquid, and beautify the appearance of the product. Therefore, the embossing process on the surface of the absorbent is very important.

[0003] During the production process of nursing pads, the absorbent material enters between the pattern roller and the smooth roller from the left side. The surface of the pattern roller is engraved with a pattern composed of concave and convex parts. Under the pressure of the cylinder, the pattern roller presses the pattern on the surface of the absorbent through the rotation of the pattern roller and the smooth roller. Since the pressure provided by the cylinder is very high, the toilet paper on the surface of the absorbent may stick to the surface of the pattern roller, and rotate with the pattern roller and get entangled on the roller surface, tearing the absorbent. If the entanglement phenomenon is not handled in time, the entanglement will become more and more, and the tearing surface will become larger and larger. Finally, the entanglement will cause blockage and shutdown, resulting in a large amount of waste.

[0004] Since the embossing area of ​​the embossing roller is very wide (equal to the width of the absorbent body), and the bonding point may occur at any position within the embossing width area, with position uncertainty, it is also difficult to detect and prevent it through conventional fixed-point detection devices.

[0005] Therefore, in order to correct the above-mentioned defects, we propose a pressure roller device that can automatically detect winding. Utility Model Content

[0006] The technical problem solved by the utility model is to provide a pressure roller device capable of automatically detecting winding.

[0007] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a pressure roller device capable of automatically detecting winding, comprising a frame, in which a smooth roller and a flower roller that can be adjusted up and down are installed, the surface of the flower roller has a concave and convex pattern, the flower roller is above the smooth roller, an L-shaped detection lever is installed in the frame through an axle pin, the L-shaped detection lever can swing along the axle pin, the L-shaped detection lever is in front of the flower roller, the bottom of the vertical part of the L-shaped detection lever is point A, the outer end of the horizontal part of the L-shaped detection lever is point B, there is a contact switch above point B, and it lightly touches the electric shock switch, and point A contacts the highest point on one side of the flower roller.

[0008] Furthermore, the length of the horizontal portion of the L-shaped detection lever is greater than the length of the vertical portion of the L-shaped detection lever.

[0009] Furthermore, the L-shaped detection lever is as wide as the flower roller.

[0010] Furthermore, the frame is composed of an outer plate, an inner plate, a bottom plate, and a top plate.

[0011] Furthermore, both ends of the smooth roller are fixed in the frame through bearings, both ends of the pattern roller are connected to bearing slides, a cylinder is installed on the top of the frame, and the telescopic end of the cylinder extends to the frame and is connected to the bearing slide.

[0012] Compared with the prior art, the beneficial effects of the utility model are: the device targets the phenomenon of the absorbent body wrapping around the roller surface, and through an online real-time detection device, it can monitor the wrapping phenomenon at any position in the entire area of ​​the embossing roller. Once the wrapping occurs, it will immediately trigger an alarm and shut down to prevent the generation of a large amount of waste, and the detection trigger structure used is simple and the triggering is sensitive.

[0018] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0019] The utility model provides a technical solution:

[0020] See also Figure 1-3, a pressure roller device capable of automatically detecting winding, comprising a frame consisting of an outer plate 4, an inner plate 3, a bottom plate 5, and a top plate 6. Both ends of a smooth roller 2 are fixed in the frame by bearings, that is, the smooth roller 2 can only rotate but cannot change its position, while the flower roller 1 can be adjusted up and down in the frame by the action of a cylinder 8 to change the distance between it and the smooth roller 2. An L-shaped detection lever 9 is installed between the inner and outer plates by an axle pin and can rotate around a fulcrum O. Point A must contact the highest point on one side of the flower roller 1 to ensure that the flower roller 1 does not push the L-shaped detection lever 9 to rotate and trigger an alarm when sliding up and down, and the contact switch is lightly touched above point B.

[0021] The absorbent material enters between the flower roller 1 and the smooth roller 2 from the left side. The flower roller 1 is pushed downward by the pressure of the cylinder 8 to pressurize the absorbent material. The embossing is completed and output to the right side through the opposite rotation of the flower roller 1 and the smooth roller 2; if the absorbent material adheres to the flower roller 1 and rotates with it, it will trigger the L-shaped detection lever 9 when it rotates to point A, causing the L-shaped detection lever 9 to rotate around the fulcrum O, and the length of the horizontal part of the L-shaped detection lever 9 is greater than the length of the vertical part of the L-shaped detection lever 9. Even a small displacement of point A can be magnified by the lever arm at point B, so that point B pushes the contact switch upward to alarm. Point A of the L-shaped detection lever 9 is in contact with the flower roller 1 along the entire length of the embossing area. Therefore, when bonding and entanglement occur at any position in the embossing area, point A can be triggered to cause displacement, thereby causing an alarm shutdown.

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