Description

Technical Field

[0001] This utility model relates to the field of cutter shaft equipment technology, specifically a circular magnetic cutter shaft. Background Technology

[0002] A circular blade, also known as a circular cutter or disc cutter, is a type of cutting tool with a rounded edge. It is mainly divided into two categories: carving circular blades and industrial slitting circular blades. Carving circular blades are suitable for processing round surfaces in traditional flower carving, such as leaves, petals, and stems. They are highly adaptable to lateral movement and can handle various undulations. Industrial slitting circular blades are high-precision mechanical blades widely used in industries such as papermaking, packaging, printing, electronics, and textiles. They are used to slit materials including films, metal foils, tapes, textiles, and electronic adhesive products.

[0003] However, the current circular cutter magnetic shaft has the following problems: traditional circular cutter magnetic shafts are not convenient for rapid positioning and are not conducive to efficient installation. Utility Model Content

[0004] The purpose of this invention is to provide a magnetic cutter shaft for circular knives to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a circular magnetic cutter shaft, comprising a cutter shaft structure and a circular blade structure, wherein the cutter shaft structure is provided with a circular blade structure via an upper limit pin;

[0006] The cutter shaft structure is fixed by a limiting component and a shaft body. The positioning piece inside the limiting component is adapted to the circular blade structure, and the spring positioning pin is pin-connected to the circular blade structure for positioning. Pressing the lifting bracket controls the position of the spring positioning pin to control the limiting state.

[0007] The circular blade structure is used for machining. The soft sheet metal blade is connected to the positioning plate via a connector block. The first and second insert shafts are pinned to a spring positioning pin. When the circular blade structure is inserted into the limiting component, the connector block enters the positioning plate, and the first and second insert shafts also enter the positioning plate. The first and second insert shafts compress the spring positioning pin. After reaching the appropriate position, the spring positioning pin connects to the groove on the first and second insert shafts. At this point, the spring positioning pin passes through the groove to position the circular blade structure. The connector block is magnetically attracted and fixed, thus completing the installation. Afterward, the user connects the limiting component to an external tool holder via the shaft, allowing control via external mechanical equipment to assist in machining production.

[0008] Specifically, the cutter shaft structure includes a limiting component and a shaft body, with the limiting component fixedly connected to the side end of the shaft body.

[0009] Specifically, the limiting component includes a positioning plate and a magnet. The positioning plate and the magnet are arranged in an alternating ring. A limiting frame is fixedly connected to the positioning plate. A spring positioning pin is telescopically connected to the limiting frame. A lifting frame is fixedly provided at the center of the spring positioning pin. The lifting frame passes through the magnet. The retraction and adjustment of the spring positioning pin are controlled by pressing the lifting frame.

[0010] Specifically, the limiting component has a central shaft at its center, which is fixedly connected to a magnet and a positioning piece.

[0011] Specifically, the circular blade structure includes a flexible sheet metal blade, a connecting block, a first insert shaft, and a second insert shaft. The connecting block is fixedly located at the center of the side end of the flexible sheet metal blade. The side end of the flexible sheet metal blade also has a first insert shaft and a second insert shaft, which are flush. By installing the blade shaft structure, a limiting component and a shaft assembly are combined within the blade shaft structure. The limiting component is easily connected to the blade holder via the shaft. The central shaft is fixedly installed with a positioning plate and a magnet. A limiting bracket is installed on the positioning plate, which is used for installing the spring positioning pin. The lifting bracket, by pressing, can control the retraction and adjustment of the spring positioning pin, thereby controlling the limiting state between the spring positioning pin and the second insert shaft. A groove is opened at the end of the second insert shaft, which is adapted to fit the spring positioning pin for positioning and installation of the circular blade structure. Through the connecting block, the first insert shaft, and the second insert shaft, the circular blade structure is positioned and installed, enabling the flexible sheet metal blade to be processed and produced.

[0012] Specifically, the flexible sheet metal knife is inserted into the slot on the positioning piece via a connector, and the connector is magnetically attracted by a magnet.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] By installing a cutter shaft structure, the cutter shaft structure is combined with a limiting component and a shaft body. The limiting component is easily connected to the cutter holder via the shaft body. The central shaft is fixedly set with a positioning plate and a magnet. A limiting bracket is set on the positioning plate, which is used for the installation of the spring positioning pin. The lifting bracket can control the retraction adjustment of the spring positioning pin by pressing, thereby controlling the limiting state of the spring positioning pin and the second insert shaft. A groove is opened at the end of the second insert shaft, which is adapted to the spring positioning pin for the positioning and installation of the circular blade structure.
