Description

Technical Field

[0001] This invention relates to the field of printer technology, and in particular to a multi-segment floating print plate mechanism for dot matrix printers. Background Technology

[0002] Currently, all dot matrix printers on the market for printing ID cards use a single-piece printing plate. While a single-piece printing plate can solve most printing problems, when the ID card is opened, the thinner side of the paper cannot be printed due to the uneven thickness on both sides. Most printer manufacturers guide customers to flip the paper back and forth to make both sides of the ID card the same thickness. However, this method requires certain conditions from the customer, and after balancing, the ridge in the middle will be relatively high, resulting in poor print quality. Therefore, there is an urgent need for a printer that can be compatible with printing ID cards. Summary of the Invention

[0003] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0004] A multi-segment floating print plate mechanism for a dot matrix printer is provided, comprising: an outer wall panel, a lifting slider, a floating support plate, a first floating spring, a first floating limit assembly, a first print plate, a second print plate, a second floating spring, a guide block, and a second floating limit assembly;

[0005] The floating support plate is elastically connected to the outer wall panel through a first floating spring, so that the floating support plate floats up and down. The two sides of the outer wall panel are provided with lifting sliders. The two sides of the floating support plate are respectively movably disposed in the slide grooves of the lifting sliders to guide the floating support plate to rise and fall. The bottom of the floating support plate is provided with a first floating limit component that is movably connected to the lifting slider to limit the rising and falling height of the floating support plate.

[0006] The outer sides of the first printing plate and the second printing plate are rotatably connected to the outer wall panel, and the lower parts of the first printing plate and the second printing plate are independently and movably connected to the floating support plate by the second floating spring. A gap for placing the spine of the book is provided between the first printing plate and the second printing plate. The guide block is provided on the floating support plate between the first printing plate and the second printing plate, and the first printing plate and the second printing plate are movably connected to the guide block by the second floating limiting component to limit the lifting height of the first printing plate and the second printing plate, respectively.

[0007] In a preferred embodiment of the present invention, the first floating limit component includes a first lifting limit pin, and each of the lower ends of both sides of the floating support plate is provided with a first lifting limit pin, and the protruding block at the bottom of the first lifting limit pin is movably connected to the bottom surface of the lifting slider.

[0008] In a preferred embodiment of the present invention, the second floating limit component includes a second lifting limit pin, and each of the lower inner sides of the first printing plate and the second printing plate is provided with a second lifting limit pin, and the protruding block at the bottom of the second lifting limit pin is movably connected to the bottom surface of the guide block.

[0009] In a preferred embodiment of the present invention, the second floating spring is wound around the second lifting limit pin between the printing plate and the guide block.

[0010] In a preferred embodiment of the present invention, the exterior wall panel includes a left wall panel and a right wall panel.

[0011] In a preferred embodiment of the present invention, the outer sides of the first printing plate and the second printing plate are connected to the floating support plate via hinges.

[0012] In a preferred embodiment of the present invention, a pair of flat plates are provided on the outer wall panel above the printing plate. The pair of flat plates are in contact with the first printing plate and the second printing plate, so that the printing plate remains horizontal when there is no certificate medium.

[0013] The beneficial effects of this invention are: it allows the printing plate to adapt to the printing needs of different thickness sides of the certificate, and effectively reduces the impact of the certificate spine on the printing quality. It not only improves the accuracy, stability and efficiency of printing, but also improves the versatility of the product. It is simple to operate and convenient to use. Attached Figure Description
