Description

Technical Field

[0001] The utility model relates to the technical field of strapping machines, in particular to a cutting knife mechanism for a strapping machine. Background Technique

[0002] Strapping generally refers to a packaging operation that directly binds single or several packages tightly with ropes, steel bands, plastic tapes, etc. for easy transportation, storage, and handling. It is the last process of packaging. A strapping machine refers to a device for strapping goods or items. Due to different requirements for strapping different packages, there are various strapping forms, and the strapped packages are mostly cuboids and cubes. Common strapping forms include single - channel, double - channel, cross - cross, grid, and multi - channel cross, etc. Usually, several parallel strappings are called a group; cross - strapping is two groups of strappings, with each group being one channel, grid - shaped strapping is two groups of strappings, with each group being two channels. A cutting knife is a tool for cutting materials, especially suitable for cutting strip - shaped materials such as tapes, plastic films, etc. They usually have sharp blades and appropriate designs to maintain stability and precision during the cutting process. The application scope of cutting knives is extensive, including but not limited to industries such as packaging, printing, textile, and electronics. For example, in the electronics industry, cutting knives are used to cut tapes, plastic films, etc. to ensure the quality and appearance of products. In addition, there are some specially designed cutting knives, such as the hot - cutting knife on a computer - controlled full - automatic film cutting machine, which is used to cut materials at high speed and efficiently. The design and material selection (such as tungsten steel, cemented carbide, etc.) of these cutting knives ensure their durability and cutting efficiency, meeting the application requirements of different industries.

[0003] For example, the application number: CN202123321262.2, the utility model discloses a modern logistics chemical drum carrier, including a chemical drum transport vehicle body. The chemical drum transport vehicle body is provided with a feeding frame, a driving handle, and a plurality of universal locking wheels. A frame door is hinged to the opening end of the feeding frame. A rolling mechanism is arranged at the bottom of the feeding frame. A limiting mechanism is arranged on the frame door. The lower end of the feeding frame is fixedly connected with a plurality of shock - absorbing mechanisms, and each of the plurality of shock - absorbing mechanisms is fixedly connected with each of the plurality of universal locking wheels respectively. The rolling mechanism includes a groove arranged at the bottom of the feeding frame, and a plurality of guide rollers are rotatably connected in the groove. The limiting mechanism includes a slide rod slidably penetrating through the frame door, and a threaded rod is threaded through the frame door. One end of the slide rod located inside the feeding frame is fixedly connected with a limiting plate. The utility model is not only convenient for workers to move the chemical drums on the chemical drum transport vehicle body, but also can effectively improve the stability of the chemical drums on the chemical drum transport vehicle body.

[0020] The following further describes in detail the implementation mode of the present utility model with reference to the drawings and embodiments. The following embodiments are used to illustrate the present utility model, but cannot be used to limit the scope of the present utility model.

[0021] As Figures 1 - 3 shown, a tape cutting knife mechanism of a strapping machine includes a support frame 1 and a support plate 9. Mounting feet 2 are arranged on the outer side of the bottom end of the support frame 1, and a fixing plate 7 is arranged at the bottom end of the support frame 1. A micro cylinder 8 is installed at the upper end of the fixing plate 7. The support plate 9 is arranged above the micro cylinder 8. A control box 3 is installed at the upper end of the support frame 1, and a cylinder 4 is arranged at the bottom end of the control box 3. Further, a moving tool holder 5 is arranged at the bottom end of the cylinder 4, and a tape cutting blade 6 is installed at the bottom of the moving tool holder 5. Further, a built-in groove 10 is opened inside the support frame 1, and a connecting plate 11 is arranged inside the built-in groove 10. Further, an electric telescopic rod 12 is installed at the upper end of the connecting plate 11, and a connecting rod 13 is arranged at the end of the electric telescopic rod 12. Further, a connecting plate 14 is arranged at the end of the connecting rod 13, and the connecting plate 14 is connected to the connecting rod 13 in a snap-fit manner. Further, the shape and structure of the connecting plate 14 are consistent with the shape and structure of the support plate 9, and the support plate 9 and the micro cylinder 8 are of an integrated structure. By driving the support plate 9 to move up and down through the micro cylinder 8, the support plate 9 can be attached to the strapping tape to provide a supporting force for the strapping tape. Under the action of the cylinder 4, the tape cutting blade 6 can provide a cutting pressure for the support plate 9, thereby cutting the strapping tape. The electric telescopic rod 12 can drive the connecting plate 14 to move up and down, so that the height of the connecting plate 14 is the same as that of the support plate 9, which can support the strapping tape and facilitate cutting.
