Description

Technical Field

[0001] The utility model relates to the field of printing machines, in particular to a walking system of a direct injection printing machine track wheel combined printing trolley. Background Art

[0002] A printing trolley of a printing machine usually consists of a guide rail, a trolley base, a nozzle mounting bracket, nozzles and related transmission and control systems. The guide rail is used to guide the precise movement of the trolley in the horizontal direction to ensure that the nozzles can print according to a predetermined path. The trolley base bears the nozzle mounting bracket, nozzles and related transmission mechanisms. The printing trolley is responsible for precisely moving the nozzles during the printing process to complete the pattern printing task. Currently, the grating bars for the movement of the printing trolley are usually clamped and fixed to the support cross beam by several supports. When disassembling and maintaining, each support needs to be disassembled one by one, and the operation is rather troublesome. And the guide rail for sliding and supporting the printing trolley is usually arranged on the side of the support beam. The guide rail bears the self-weight of the printing trolley at the front, but there is no support mechanism at the rear of the printing trolley, and various control components are arranged on the top plate at the rear of the printing trolley, resulting in unbalanced front and rear supports and affecting the stability of the movement of the printing trolley.

Specific implementation mode

[0022] Embodiment 1, referring to the attached Figures 1-3 Figs. 5-6, a walking system for a direct-injection printing machine rail wheel combination printing trolley, comprising a trolley mechanism 41 slidably mounted on a cross beam 43, a grooved bracket 42 fixedly connected to the outer side surface of the cross beam, the drag chain 421 of the trolley mechanism being arranged in the grooved bracket, and the grooved bracket providing moving support for the drag chain.

Between the two cross brace rollers 412, there is a vertical brace roller 413. The cross brace rollers press against the inner side plate surface of the grooved bracket 42, and the cross brace rollers are used for horizontally supporting and rolling to support the trolley mechanism 41, playing a role of horizontal rolling limit and sharing the pressure exerted by the trolley mechanism 41 on the guide rail 446. The vertical brace roller 413 presses against the bottom surface of the grooved bracket 42; at both ends of the inner side of the cross beam 43, there are clamping plate supports 431, and the clamping plate support includes a fixing plate and a clamping plate.

A plurality of positioning posts 434 are arranged side by side at the lower portion of the auxiliary support 433, and the positioning posts are vertically arranged in an integral manner on the side of the auxiliary support 433. Positioning holes are provided at corresponding positions of the grating bars 432, and the positioning holes are clamped on the positioning posts 434. The lower ends of the grating bars 432 are sleeved and fixed by the positioning posts and the positioning holes, and a magnetic sheet 435 is provided between the auxiliary support 433 and the grating bars 432, and the lower portion of the magnetic sheet is sleeved on the positioning posts 434. The sleeve structure fixes the position of the magnetic sheet 435.
