Description

Technical Field

[0001] This utility model belongs to the technical field of cigarette packaging equipment, specifically relating to a cigarette label paper feeding structure. Background Technology

[0002] The YB25 packaging machine's label paper supply is primarily achieved through compressed air flowing through numerous small holes on the left and right separating plates. As the separating plates reciprocate, the air slightly lifts the label paper. When the fan-shaped suction roller passes the label paper magazine, its negative pressure suction port picks up the bottom label paper, rotating clockwise as it moves to achieve frictionless separation from the upper label paper. When the label paper held by the fan-shaped suction roller reaches the space between the feeding roller and the guide roller, the vacuum suction port of the suction roller closes, causing the label paper to change from horizontal feeding to vertical dropping under the action of the feeding roller and the upper and lower guide rollers, before being sent to the next process for label paper gluing.

[0003] To enhance product competitiveness and promote the development of mid-to-high-end cigarette brands, the company has introduced an innovative soft-pack hardening packaging process. In actual production, as the label paper is conveyed by the feeding rollers and upper and lower guide rollers, the changes in the material parameters of the soft-pack hardened label paper lead to the following technical problems: The increased thickness of the label paper after hardening increases its bending stiffness, making it difficult to conform to the surface contour of the feeding rollers, resulting in uneven friction distribution between the feeding rollers and the label paper; the increased stiffness of the label paper enhances its resistance to deformation, reducing the contact area when passing through the feeding rollers, causing insufficient or unbalanced effective friction; these combined effects cause frequent lateral skew of the label paper during conveying, which can lead to blockages in severe cases. Utility Model Content

[0004] This utility model provides a cigarette label paper feeding structure to address the above-mentioned problems.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A cigarette label paper feeding structure includes a feeding roller, which is mounted on a drive shaft. The drive shaft is rotatably mounted on a support via bearings, and the support is fixedly connected to a frame. The outer arc surface of the feeding roller contacts and engages with an upper guide wheel and a lower guide wheel. The feeding roller, together with the upper and lower guide wheels, conveys the label paper. A fan-shaped notch is provided on the outer arc surface of the feeding roller. A guide plate is provided on the outer side of the feeding roller. The arc-shaped turning part of the guide plate is coaxially mounted with the feeding roller. The inner arc surface of the guide plate is coplanar with the outer arc surface of the feeding roller. A slot is provided on the guide plate to allow space for the upper and lower guide wheels.

[0006] Furthermore, a shoulder is provided on the drive shaft, and the left end face of the paper feeding roller forms an axial positioning fit with the shoulder. The right end face of the paper feeding roller is fixedly connected to the retaining ring of the flange shaft by bolts, and the bushing of the flange shaft is fixedly connected to the drive shaft by set screws.

[0007] Furthermore, a tapered groove is provided on the drive shaft, and the bushing engages with the tapered groove through a set screw, thereby fixing the drive shaft to the flange shaft.

[0008] Furthermore, multiple arc-shaped grooves are provided on the retaining ring, and connecting holes corresponding to the arc-shaped grooves are provided on the paper feeding roller. Each arc-shaped groove is provided with multiple connecting holes to facilitate the adjustment of the position of the fan-shaped notch.

[0009] Furthermore, the paper feeding roller adopts a composite structure. The inner ring is made of 20CrMnTi material to ensure structural support and transmission stability. The outer ring is made of polyurethane material with a hardness of HA85. Its elasticity, wear resistance and suitable friction characteristics meet the working conditions of receiving and releasing paper during the label paper conveying process.

[0010] Furthermore, the guide plate is fixedly mounted on the connecting plate, and the connecting plate is fixedly connected to the frame.

[0011] Compared with the prior art, the present invention has the following advantages: This utility model proposes a cigarette label paper feeding structure, which is reasonable and effective. The guide plate ensures the degree of deformation of the label paper, thereby ensuring the contact area between the label paper and the feeding roller, and ensuring that the contact friction between the label paper and the feeding roller meets the conveying requirements. The outer ring of the feeding roller is made of polyurethane material. When the feeding roller works with the upper and lower guide rollers to receive and convey the paper, the outer ring of the polyurethane material deforms slightly, resulting in a larger contact area compared to existing alloy feeding rollers, thus ensuring more uniform friction during label paper conveying. At the same time, the flange shaft retaining ring has an arc groove, which can adjust the position of the fan-shaped notch of the feeding roller, accurately matching the label paper receiving and release phase, solving the problems of fixed phase and poor adaptability of traditional structures, improving the success rate of label paper conveying after soft pack hardening, reducing auxiliary material consumption, and improving production efficiency.
