[0005] Therefore, in the use of sealing machine, the ribbon used for printing needs to be opened to replace the ribbon after the printing component is moved outside the shell. After replacing the ribbon, the printing component is pushed back into the shell. When the printing component is pushed back into the shell, it is necessary to accurately position the printing component at the specified position and have a certain fixing force, because the printing component is often manually pulled out to replace the ribbon, the fixing force of the printing component cannot be too large, and it is also necessary to prevent shaking during printing (causing irregular and blurred printing font defects), and it is also necessary to ensure that the printing component can be easily pulled out by hand during operation. SUMMARY

[0006] To solve the above problems, the utility model provides a kind of side stretch printing device and sealing machine for sealing machine, and the technical solutions are as follows:

[0007] A kind of stretch printing device for the side of sealing machine, including linear guide rail, linear guide rail is slidably connected on linear guide rail, printing assembly is fixedly installed in linear guide rail, and still be installed with stretch positioning assembly on printing assembly or linear guide rail.

[0008] The printing assembly includes a print head fixing frame, wherein a needle type print head and a ribbon fixing frame are installed on the print head fixing frame, a ribbon is installed on the ribbon fixing frame, a drive hole of the ribbon is assembled with a ribbon drive motor output shaft, the ribbon drive motor is fixedly connected on the print head fixing frame, and a printing wheel is installed opposite to the needle type print head, the printing wheel is installed on the print head fixing frame through a printing wheel pin shaft, and the print head fixing frame is fixed on the linear guide rail.

[0009] The side opening door of the sealing machine shell is opened or closed, and the printing assembly can be pulled out or pushed into the shell and positioned by pulling the stretch positioning assembly, so that the replacement of the sealing machine ribbon is facilitated.

[0010] Further, the stretch positioning assembly is a hinge mechanism.

[0011] One end of the hinge mechanism is connected with the printing assembly or the linear guide rail, and the other end is connected with the inner side of the side opening door of the sealing machine.

[0012] The hinge mechanism can achieve a certain resistance when opening and closing the sealing machine, thereby achieving the function of quick fixing. When the side opening door of the sealing machine shell is opened, the side opening door drives the printing assembly to extend out of the sealing machine shell through the hinge, which is very convenient for replacing the sealing machine ribbon. When the side opening door of the sealing machine shell is closed, the side opening door drives the printing assembly to push into the sealing machine shell through the hinge, and the hinge reaches the closed state at this time, which provides a certain elastic force to the maintenance door to prevent the maintenance door from being opened automatically, and the printing component is pushed against through the connecting rod. The hinge mechanism is more convenient and reliable relative to the mutually matched locking buckle and buckle rebounder, is more convenient to use, and has lower cost.

[0013] Another preferred scheme is that the stretching positioning assembly is a stretching component and a positioning fixing component installed on the printing assembly or the linear guide rail.

[0014] The positioning fixing component is a positioning plate installed on the printing assembly or the linear guide rail and a limiting plate installed inside the sealing machine, and a suction component is installed between the positioning plate and the limiting plate.

[0015] The suction component is a magnet or a magic tape, or a buckle, or a convex groove structure, or a pearl structure.

[0016] The stretching component is a bent plate or a handle or a pull rod fixed on the print head fixing frame in the printing assembly, or a handle or a pull rod fixed on the linear guide rail, or the front end of the linear guide rail. The positioning plate in the positioning fixing component is fixed with the print head fixing frame in the printing assembly, or is fixed on the linear guide rail alone. The limiting plate in the positioning fixing component is installed inside the sealing machine. A suction component is installed between the positioning plate and the limiting plate. The suction component can be a magnet or a magic tape, or a buckle, or a convex groove structure, or a pearl structure.

[0017] The magnet is used as the suction component, and the magnet is attracted, thereby fixing the printing assembly. The magnet also has the function of positioning, and the printing assembly is positioned at an accurate position. When the printing assembly is pulled out, the printing head can be moved outwards as long as the pulling force is greater than the suction force of the magnet. The size of the suction force can be changed by selecting the size or number of the magnet, thereby realizing that the printing component can be easily pulled out.

[0018] The male face of the magic tape is used to quickly hook the soft fiber of the female face to realize the quick locking function. The male face fixed on the printing assembly and the female face fixed on the shell are buckled to fix the printing assembly, and the female face also plays a positioning role to fix the printing assembly at the accurate position. When pulling out the printing assembly, the printing head can be moved outwards by only separating the male face from the female face. Because the buckling force of the male face and the female face of the magic tape is not large, the printing assembly can be easily pulled out.

[0019] The elastic deformation of the male buckle and the female buckle of the buckle and the deformation of the buckle structure are used to realize the quick locking function. The male buckle fixed on the printing head and the female buckle fixed on the shell are buckled to fix the printing head, and the female buckle also plays a positioning role to fix the printing assembly at the accurate position. When pulling out the printing assembly, the printing head can be moved outwards by only pulling the male buckle out of the female buckle. The size of the elastic force is adjusted by adjusting the adjusting screw on the female buckle to achieve the appropriate size of the fixing force, so that the printing assembly can be easily pulled out.

[0020] The male face and the female face of the buckle structure are used to realize the quick locking function. The male face fixed on the printing assembly and the female face fixed on the shell are buckled to fix the printing assembly, and the female face also plays a positioning role to fix the printing assembly at the accurate position. When pulling out the printing assembly, the printing head can be moved outwards by only pulling the male face out of the female face. The size of the elastic force is adjusted by adjusting the design height of the male face to achieve the appropriate size of the fixing force, so that the printing assembly can be easily pulled out.

[0021] The above-mentioned magnet or magic tape, buckle, or male face and female face structure, or bump bead structure is selected as the attracting component, which has a long service life and low price, and does not need to be replaced in a short time. The stretching positioning assembly structure is compact, simple and reliable, easy to use, and has low replacement cost and material cost.

[0022] Another preferred embodiment is that the positioning and fixing component is a male face and female face structure or a bump bead structure installed between the printing assembly and the inside of the sealing machine shell.

[0023] By adopting this scheme, the positioning plate and the limiting plate can be omitted, and the device is simpler.

[0024] Another preferred embodiment is that the positioning and fixing component is an elastic stopper installed on the printing assembly or the linear guide rail.

[0025] The printing assembly is secured when the side door is closed using a flexible stop, a positioning plate mounted on the printing assembly or linear guide, and a limiting plate installed inside the sealing machine. One side of the flexible stop is fixed to the print head holder of the printing assembly or the front end of the linear guide, while the other side presses against the side door of the sealing machine. When the printing assembly is pushed back into the housing after ribbon replacement, the flexible stop on the access door, the positioning plate on the printing assembly or linear guide, and the limiting plate inside the sealing machine hold the printing assembly in place. The thickness of the flexible stop is slightly greater than the distance between the side door and the printing assembly. When the side door is locked, the printing assembly is fixed in the corresponding position. When the side door is opened, the printing assembly can be easily pulled out. The structure is compact and robust, simple and easy to operate, and highly efficient.

[0026] Alternatively, a sealing machine can be designed, including a housing, a core, a display unit, and a control unit. An opening is provided on the side of the housing, and a side-opening door is installed at the opening. The machine also includes a side stretching and printing device for any of the above-mentioned sealing machines, which is installed inside the housing and corresponds to the side-opening door.

[0027] Furthermore, the side-opening door is secured to the housing by magnets, Velcro, or clips.

[0028] The beneficial effects of this utility model are: the printing component of the sealing machine with this utility model can not only pop out and be quickly reset and fixed, but also fully extend to the outside of the sealing machine after the printing component is pulled out, making it convenient to replace the ribbon or accessories. Moreover, the structure is simpler and more reliable, the service life is longer, the use is faster and more convenient, and the cost is lower. Attached Figure Description
