Description

TECHNICAL FIELD

[0001] The utility model relates to rewinding equipment technical field, especially a kind of conveying guide roller mechanism of rewinding machine. BACKGROUND

[0002] Aluminum foil paper is an indispensable auxiliary material in cigarette packaging, and its main functions include heat insulation, moisture retention and aroma preservation. Traditionally, aluminum foil paper is manufactured using a composite process, which involves bonding aluminum foil and backing paper with an adhesive under certain pressure, followed by processes such as color coating, drying, embossing, and cutting. During production, approximately 5%-10% of the products may need to be rewound to remove defective parts due to joint between raw paper and aluminum foil, joint during raw material replacement, and quality defects during production. Therefore, it is necessary to remove these defects through rewinding and recycle the non-defective products. This not only reduces waste but also improves the overall quality of the final product.

[0003] Currently, widely used rewinding machines guide and transport aluminum foil paper by setting multiple sets of conveying guide roller mechanisms. These guide roller mechanisms mainly rely on fixed metal retaining rings to limit the aluminum foil paper to ensure that the edges of the aluminum foil paper do not exceed the range of the retaining ring, thereby ensuring the flatness of the paper roll surface. However, during the rewinding process, when the production speed reaches 300 meters per minute, high temperatures are generated due to friction between the high-speed moving aluminum foil paper and the metal retaining ring, causing the end of the aluminum foil paper to oxidize and turn black. Although this phenomenon does not affect the normal use of the product, the end surface of the product after rewinding still has a black quality problem compared to the normally cut (whiter) product. Therefore, it is necessary to improve this. SUMMARY

[0004] The technical problem to be solved by the utility model is to provide a conveying guide roller mechanism of rewinding machine.

[0005] To solve the above technical problems, the technical scheme of the utility model is as follows:

[0006] A conveying guide roller mechanism of rewinding machine, comprising a guide roller body and a locking nut screwed on the guide roller body; the guide roller body includes a guide section for guiding aluminum foil paper, two limiting sections respectively arranged at both ends of the guide section, and a mounting section arranged at the end of one of the limiting sections; the guide section, the limiting sections, and the mounting section are all cylindrical in shape, and their outer diameters decrease in turn; the locking nut is screwed on the mounting section; a non-metallic retaining ring is rotatably installed on each limiting section; the inner diameter of the non-metallic retaining ring is smaller than the outer diameter of the guide section, and the outer diameter is larger than the outer diameter of the guide section.

[0007] Preferably, the non-metallic retaining ring is rotatably installed on the limiting section through a bearing.

[0008] Preferably, the bearing slidingly covers the limiting section, and the limiting section is screwed with adjusting nuts on both sides of the bearing.

[0009] Preferably, the non-metallic check ring comprises a mounting portion in clamping cooperation with the outer ring of the bearing, and a limiting portion in the shape of a ring arranged at one end of the mounting portion close to the guide section; the inner diameter of the limiting portion is smaller than the outer diameter of the guide section, and the outer diameter of the limiting portion is larger than the outer diameter of the guide section.

[0010] Preferably, the adjusting nuts between the non-metallic check ring and the guide section are replaced by springs.

[0011] Preferably, the adjusting nuts are slotted nuts.

[0012] Preferably, the bearing is a nylon bearing.

[0013] Preferably, the guide roller body is in the shape of a hollow body.

[0014] The above technical solution has the following advantages:

[0015] The non-metallic check ring can freely rotate, and when the non-metallic check ring contacts the edge of the aluminum foil, the friction between the two can be effectively reduced. Therefore, compared with the traditional fixed metal check ring, it can significantly reduce the high temperature generated by friction, thereby avoiding or at least reducing the oxidation and blackening phenomenon of the edge of the aluminum foil caused by high temperature. In addition, the non-metallic check ring has a lighter weight, which makes it have better follow-up when it contacts the edge of the aluminum foil, that is, it can rotate more smoothly with the movement of the aluminum foil. Such a design not only further reduces the wear of the edge of the aluminum foil, but also prolongs the service life of the non-metallic check ring to some extent. In this way, the quality of the aluminum foil is improved, and the production cost is reduced. BRIEF DESCRIPTION OF DRAWINGS
