Description

Technical Field

[0001] The utility model relates to the field of printers, in particular to a single-layer adjusting device for a bottom plate of a trolley and a printer. Background Art

[0002] In the printer equipment currently in use, the printer carriage is the core component, and its main function is to carry the printer nozzle. The printer nozzle is installed on the bottom plate of the carriage through the nozzle base, and then connected to the ink tube. At present, the bottom plate of the printer carriage is usually designed to have at least two layers of adjustment structure, one layer is used to adjust the rotation angle, and the other layer is used to adjust the spacing in the front and rear directions. The two layers of adjustment complement each other and ultimately achieve precise adjustment. However, with the demand for refinement and high-end printer equipment, as well as cost requirements, the overall volume of the printer is gradually shrinking, especially the thickness of the nozzle base is constantly shrinking. The double-layer structure not only takes up too much space, but also requires more accessories. In order to meet the precision requirements, it is necessary to improve the precision and assembly precision of multiple accessories themselves, resulting in serious limitations on high-end models. Therefore, designing a new type of trolley bottom plate assembly with a thinner thickness, fewer parts, and relatively low cost has become an urgent problem that technicians in this field need to solve.

[0003] The invention patent with the authorization announcement number CN114701269B discloses a single-layer trolley bottom plate assembly, which includes a trolley bottom plate, a plurality of nozzle bases, a rotation adjustment assembly and a spacing adjustment assembly. The nozzle bases are regularly arranged on the trolley bottom plate, and the nozzle bases include a reference base and an adjustment base; the trolley bottom plate is provided with a mounting positioning frame that is tightly matched on all sides corresponding to the reference base, and the trolley bottom plate is provided with a mounting positioning frame that leaves a rotation margin and a spacing adjustment margin corresponding to the adjustment base; the rotation adjustment assembly includes a limit column and a fixed seat to provide a rotation margin for the nozzle base; the spacing adjustment assembly includes a positioning column and a positioning seat, which cooperate with the rotation adjustment assembly to provide a forward and backward movement margin for the nozzle base. The single-layer trolley bottom plate assembly has the advantages of reduced thickness, reduced parts, and two-stage adjustment function, but there is a phenomenon of interference between the front and rear adjustment and the left and right adjustment during the adjustment process of the device, and the adjustment takes a long time.

During the front and rear adjustment process, the pin and the left and right adjustment screws will form a guiding structure for the front and rear adjustment, so that the nozzle mounting plate is subjected to a more uniform force during the front and rear adjustment process, which can avoid the left and right swing of the nozzle mounting plate when the front and rear adjustment is made.

[0021] Therefore, under the premise of simplifying the structure, the single-layer adjustment device for the bottom plate of the trolley can limit the left and right rotation of the nozzle mounting plate when moving it forward and backward, thereby reducing the difficulty of adjustment and reducing the time consumption of adjustment.
