Description

Technical Field

[0001] This utility model relates to the technical field of paper cutting wheel mechanisms, specifically a convenient blade-changing paper cutting wheel mechanism for cigarette machines. Background Technology

[0002] A cigarette machine's paper cutter wheel is a device used to cut the tipping paper in cigarette filters. It mainly consists of a wheel body and a carbide blade embedded in the wheel body. The carbide blade is usually cylindrical in shape and is tightly fitted onto the wheel body, making the paper cutter wheel structure robust, durable, and with minimal wear.

[0003] For example, announcement number CN210169030U (named "A Paper Cutting Roller Assembly for a Cigarette Machine") includes a frame, a first rotating shaft and a second rotating shaft mounted on the side surface of the frame. The outer wall of the first rotating shaft is fitted with a fitting ring via a fitting assembly. One end of the fitting ring has an integrally formed first inner shrink ring on its inner wall. A fixing bolt passes through the side surface of the first inner shrink ring. A concave groove is formed on the outer surface of the fitting ring. An insert ring is fitted onto the outer wall of the fitting ring. An insert strip is integrally formed on the inner wall of the insert ring. An extension piece is integrally formed on the inner wall of one end of the insert ring. A bolt passes through the side surface of the extension piece. Insert bodies are evenly distributed on the outer surface of the insert ring. Airflow holes are formed on the side surface of the insert bodies. The fitting assembly includes... The fitting protrusion and fitting groove are integrally formed on the inner wall of the fitting ring, and the fitting protrusion is integrally formed on the outer wall of the fitting protrusion. The fitting protrusion and the fitting groove fit together. The fitting ring is fitted onto the side surface of the second rotating shaft through the fitting groove and the fitting protrusion. A fitting assembly is added between the first rotating shaft and the fitting ring. A concave groove and a fitting strip are added between the fitting ring and the insert ring. The fixing bolts and the bolts on the side surface of the extension plate keep the fitting ring and the insert ring stable. The operator only needs to turn the bolts to remove the fitting ring and the insert ring, which makes it easy for the operator to replace the fitting ring and the insert ring of different specifications. The outer wall of the second rotating shaft is also fixed with a tool holder ring through the fitting assembly. The operator can also quickly replace the tool holder ring of different specifications on the outside of the second rotating shaft.

[0004] The aforementioned paper cutting roller uses a blade holder ring structure to assist in quick blade replacement. However, the blade holder ring is an integral structure, requiring the entire unit to be replaced when changing the cutter, which is costly and inconvenient, thus affecting the working efficiency of the paper cutting roller. To address this, we provide a convenient blade-changing paper cutting roller mechanism for cigarette machines. Utility Model Content

[0005] The purpose of this utility model is to provide a convenient blade-changing paper cutting wheel mechanism for cigarette machines, so as to solve the problem mentioned in the background art that the existing paper cutting wheel uses a blade holder ring structure to assist in quick blade changing, but the blade holder ring is an integral structure, and the whole machine needs to be replaced when changing the cutter, which is costly and has poor operation convenience, thus affecting the working efficiency of the paper cutting wheel.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a convenient blade-changing paper cutting wheel mechanism for cigarette making machines, including a bearing wheel body, a blade mounting socket integrally formed on the outer wall of the bearing wheel body, a blade head seat inserted into the blade mounting socket, a paper cutting blade at one end of the blade head seat, and the paper cutting blade and the blade head seat are an integral structure.

[0007] Also includes:

[0008] An end plate is positioned above and below the knife socket, and a support seat is provided on the inner wall of the end plate. One end of the support seat is integrally formed with a guide sleeve, and a top compression spring is provided inside the guide sleeve.

[0009] The through holes are located at both ends of the knife socket, and there are three through holes at each end. A snap-fit ​​cap is movably installed inside one of the through holes, and the two ends of the pressure spring are welded to the snap-fit ​​cap and the guide sleeve, respectively.

[0010] Preferably, the end plate has three adjustment holes inside, each corresponding to one of the three through holes. The spacing between two adjacent adjustment holes is equal, and the spacing between two adjacent through holes is also equal.

[0011] Preferably, the outer wall of the guide sleeve is provided with a guide wall groove, and a handle block is movably provided inside the guide wall groove. The handle block and the snap-fit ​​cap are an integral structure.

[0012] Preferably, both ends of the cutter head seat are provided with fixing holes, and a through hole and the fixing holes are fixedly connected by a snap-fit ​​top cap.

[0013] Preferably, a fastening bolt is provided at the connection position of one of the adjustment holes and the support seat, and the support seat and the guide sleeve are fixedly connected to the end plate by the fastening bolt.

[0014] Preferably, connecting plates are provided at the connection positions of the two end plates and the two ends of the knife socket, and the two ends of the connecting plates are welded to the end plates and the knife socket respectively.

[0015] Preferably, there are twenty-two knife-mounting sockets, and the spacing between two adjacent knife-mounting sockets is equal.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] This invention uses a corresponding connection between the blade holder and the blade mounting socket to install the paper cutting blade onto the outer wall of the support wheel. Each paper cutting blade is an independent structure. A top-pressure spring drives the snap-fit ​​cap to push out through the through hole and connect to the corresponding fixing hole, thus fixing the paper cutting blade to the support wheel. When the paper cutting blade needs to be replaced, it is not necessary to replace all the paper cutting blades; only the individual paper cutting blades need to be replaced, saving costs. When replacing the paper cutting blade, push the handle block along the guide wall groove, causing the snap-fit ​​cap to overcome the elastic pushing force of the top-pressure spring and disengage from the fixing hole. This facilitates quick replacement of the blade holder and paper cutting blade after disassembly. This overcomes the problem that existing paper cutting wheels use a blade holder ring structure to assist in quick blade replacement, but the blade holder ring is an integral structure, requiring the entire unit to be replaced when replacing the cutter, which is costly and inconvenient, thus affecting the working efficiency of the paper cutting wheel.
