Description

Technical Field

[0001] The utility model relates to the field of die-cutting of graphite heat sinks, and more specifically to an indentation-proof circular knife die. Background Art

[0002] The integral fixed circular knife is currently the most widely used die-cutting tool. During the production of graphite heat sinks, the engraving circular knife manufactured by various high-precision machine tools controlled by computer programs can perform quantitative pressing and cutting on the graphite heat sink along the shape of electronic products. The circular knife is used to die-cut electronic adhesive products, self-adhesive labels, container packaging materials and other products. After the existing circular knife is used, the graphite heat sink products made are of the same shape, which is not easy to distinguish in subsequent work.

[0003] Moreover, if embossed characters are made on the circular knife mold and pressed onto the product release film, only the products made on each line can be distinguished. Stopping the machine to replace the circular knife will reduce processing efficiency, and it is inconvenient to distinguish products made in different time periods of the same batch. When defective products appear, the person in charge of the work section at that time cannot be found out based on the number after the shift change. Utility Model Content

[0004] In order to solve the above technical problems, the utility model provides an indentation fool-proof circular knife die to solve the problem that the existing circular knives make products with the same shape after use, which is difficult to distinguish in subsequent work.

[0005] The utility model provides an indentation anti-fool circular knife die, which is achieved by the following specific technical means: it includes a main body with a cylindrical shape, a knife line is provided on the outer curved side surface of the main body, a cutting knife is provided on the outer curved side surface of the main body, an inner cavity is provided on the inner side of the left end of the main body, a positioning groove is provided on the right end of the inner cavity, a right-angle plate is provided on the inner curved side surface of the inner cavity, and through holes for bolt fixing are provided on the top surface and the left side of the right-angle plate, transmission shafts are provided on the left and right ends of the main body, and a mounting plate is provided on the right end of the transmission shaft located at the left end of the main body, and the mounting plate is horizontally penetrated by a positioning hole, and the mounting plate flange is connected to the left end of the main body, a mounting structure for connecting and installing with the main body, a number imprinting structure for imprinting font content on a product release film, that is, a finished product, and an intermittent number changing structure for automatically changing the imprinted number, and the mounting structure includes a mounting seat, a side connecting plate is provided on the right side of the top of the mounting seat, the side connecting plate is connected to the right side vertical surface of the inner cavity by bolts, and the mounting seat is fixed on the top of the right-angle plate by bolts.

[0006] According to this solution, after the mounting plate and the left flange of the main body are separated, the mounting seat is installed on the right-angle plate by bolts, and the side connecting plate and the inner cavity facade are fastened by bolts, so that the mounting seat and the circular knife can be stably installed.

[0007] In some schemes, the number stamping structure includes a crank connecting rod, a socket and a connecting seat, the crank connecting rod is arranged on the top of the mounting seat, the connecting seat is arranged on the top of the mounting seat, a vertical vertical plate is arranged on the top of the connecting seat, a horizontal tube is arranged on the right side of the vertical plate, the telescopic end of the crank connecting rod slides on the inside of the horizontal tube, the socket is arranged at the end of the telescopic end of the crank connecting rod, and a plug wheel is rotatably connected to the inside of the socket, and a number block is arranged on the curved side of the plug wheel, and the width of the font on the surface of the number block is between 0.2mm and 0.3mm.

[0008] According to the plan, after the main body of the circular knife is installed on the machine, the transmission shaft is controlled by the motor. During the rotation and embossing process of the main body, the font content is embossed onto the product release film, that is, the font content on the finished product during the circular knife die-cutting production, so as to distinguish the release film of each cavity product as quickly as possible. Embossed characters are made on the circular knife mold and pressed onto the product release film. The characters are project names or distinguishable symbols. Products with the same appearance do not increase costs and do not affect efficiency. The release film of each cavity product has the project name, which is convenient for naked eye distinction in subsequent work.

[0009] In some schemes, the intermittent number changing structure includes a ring seat and an inner shaft. The ring seat is fixedly installed inside the die-cutting machine, the ring seat is arranged on the left side of the main body, the ring seat is sleeved on the outside of the transmission shaft, the inner curved side surface of the ring seat is provided with intermittent teeth, the inner shaft is passed through the inner side of the positioning hole, a linkage gear is provided at the left end of the inner shaft, the linkage gear is meshed with the intermittent teeth for transmission, a single gear is coaxially connected to the right end of the inner shaft, the single gear is rotatably connected to the top of the mounting seat, the top of the mounting seat is rotatably connected to an intermittent wheel, a groove block is provided on the outside of the intermittent wheel, a slot is provided between the groove blocks, the intermittent wheel is meshed with the single gear, and the intermittent wheel is coaxially connected to the crank connecting rod.

[0010] According to this scheme, when the transmission shaft drives the main body to rotate and roll, the inner shaft rotates on the inside of the ring seat, and the intermittent teeth will intermittently link with the linkage gear, causing the inner shaft to rotate intermittently according to the rotation of the circular knife. The inner shaft will drive the single gear to rotate intermittently, and the single gear will drive the intermittent wheel to rotate intermittently. The intermittent wheel will drive the coaxial crank connecting rod to operate intermittently, and the crank connecting rod will drive the socket to move back and forth rapidly.

[0011] In some schemes, the intermittent number changing structure also includes bevel gear a, bevel gear b, a spring and a ballpoint pen rotator. Bevel gear a is coaxially connected to the left end of the plug wheel, bevel gear b is meshed with bevel gear a for transmission, bevel gear b is rotatably connected to the left side of the socket, a spring is sleeved on the outside of bevel gear b, and the ballpoint pen rotator is arranged at the rear end of bevel gear b.

[0012] According to this solution, during the lateral movement of the socket, the ballpoint pen rotator on its rear side will be squeezed and contacted with the vertical plate on its rear side, which can drive the bevel gear b to rotate intermittently. When the number block retreats, the bevel gear b can drive the number block coaxial with the bevel gear a to rotate intermittently, so that the exposed surface of the number block is replaced. After the number block slides outward in the positioning groove, it can be limited by the tooth structure inside the positioning groove. During the rolling process, the rotation and displacement of the insertion wheel can be prevented, so that the printed label remains stable and clear, and the number of the printed content can be automatically replaced according to the number of rotations without stopping the machine, which is convenient for distinguishing the time periods of products produced on the same line.
