Abstract

A label printer with immovable core frames includes a print-head assembly, a platen roll and immovable frames, both ends of the said print-head assembly and the roll are mounted on the immovable frames. In the label printer with immovable core frames, the relative position between the immovable frame of the print-head assembly and the frame of the roll is changeless, and the core module of the printer is not in a cantilever-like state. The core frame includes a steel plate attached to the chassis and two beams made of aluminum alloy (the print-head frame and the core frame), which makes the structure stable and accurate.

Description

Fixed movement frame label printer

The present invention relates to a label printer, and more particularly to a label printer for a stationary frame movement. BACKGROUND OF THE INVENTION Industrial label printers generally adopt a metal structure, and the core component, the movement, is the most direct component that affects the printing effect of the printer. Its accuracy and reliability directly affect the performance of the printer. The movement includes: the print head assembly 1 and the rubber roller. Component 2. Conventional industrial label printers use a cantilever or cymbal-supported movement frame structure, resulting in poor reliability of the printing module, easy to loose or even deform. As shown in FIG. 1, it is a schematic structural view of a prior art label printer, in which the print head assembly 1 and the rubber roller assembly 2 are only fixed on one side of the side wall and the other side is suspended. The use of such a structure makes the print head easy. Loose or even deformed, the reliability is deteriorated, the paper is easy to be removed, the printing effect is poor, and even serious can not be printed. SUMMARY OF THE INVENTION The technical problem to be solved by the present invention is to provide a label printer for a fixed frame movement, including a print head assembly and a rubber roller assembly, a fixing frame, and a printing assembly, in view of the above-mentioned drawbacks of the prior art. Both ends of the rubber roller assembly are fixed to the fixed frame.

In the label printer of the fixed frame movement of the present invention, the fixing frame comprises a movement side wall, a movement right cover and a bottom plate, and the movement side wall and the movement right cover are separated from each other. The bottom plate is vertical and fixed to the bottom plate.

In the label printer of the fixed frame movement according to the present invention, the side wall of the movement and the bottom plate pass the confirmation Through the screw connection, the right cover of the movement is connected to the bottom plate through the movement support leg.

In the label printer of the fixed frame movement of the present invention, the print head assembly comprises a print head module truss, a print head holder, a print head fixed on the print head holder, and the rubber roller assembly Including a rubber roller and a movement truss, the print head is pressed on the rubber roller, and the print head module truss is disposed above the print head holder to be separated from the movement truss to expose the The paper exit of the print head, the movement truss, the print head module truss, and the two ends of the rubber roller are respectively fixed on the side wall of the movement and the right cover of the movement. ,

In the label printer of the fixed frame movement of the present invention, the print head module truss and the movement yoke are fixed on the side wall of the movement and the right cover of the movement by screws i. In the label printer of the fixed frame movement of the present invention, the bottom end of the movement right cover is a folded structure, and the folding structure is provided with a fixing hole, and the movement right cover It is fixed to the bottom plate by screws passing through the fixing holes.

The invention has the beneficial effects that the label printer of the fixed frame movement of the invention not only has a fixed position between the frames of the two components of the "print head assembly" and the "rubber roller assembly", but also the entire movement module does not In the "cantilever" state. The entire movement frame consists of a steel plate fixedly attached to the machine's base plate and two aluminum alloy yokes (printhead module truss and movement truss). The structure is stable and reliable, and the accuracy is easy to guarantee. , . . .

The present invention will be further described below in conjunction with the accompanying drawings and embodiments, in which:

1 is a schematic structural view of a prior art label printer; FIG. 2 is a schematic exploded view of a fixed movement frame label printer of the present invention;

Fig. 3 is a structural schematic view showing the assembled of the fixed movement frame label printer of the present invention. detailed description

2 is a schematic view showing the structure of the explosion of the fixed-type movement frame label printer of the present invention shown in FIG. 2; and the assembled structure of the fixed movement frame label printer shown in FIG. The structure of the present invention is described.

The label printer of the stationary frame movement of the present invention includes a print head assembly, a rubber roller assembly and a fixed frame, and both ends of the print head assembly and the rubber roller assembly are mounted on a fixed frame.

The fixed frame includes a movement side wall 3, a movement right cover 4 and a bottom plate 5, and the movement side wall 3 and the movement right cover 4 are spaced apart from the bottom plate 5 and fixed to the bottom plate 5. The side wall 3 of the movement is connected to the bottom plate 5 by screws, and the right cover 4 of the movement is fixed to the bottom plate 5 through the movement support leg 6. The print head assembly includes a print head holder 101, a print head 103, a print head module gantry 102, and a print head 103. is fixed to the print head holder 101. The rubber roller assembly includes a rubber roller 201 and a movement gantry 202. Two ends of the movement truss 202 are respectively fixed on the movement side wall 3 and the movement right cover 4, and the two ends of the rubber roller 201 are mounted on the movement side wall 3 and the movement right cover 4, The print head 103 is pressed against the rubber roller 201, and the print head module truss 102 is disposed above the print head holder 101, and is separated from the movement gantry 202 by a distance away from the print head 103. The paper exit port is convenient for paper discharge, and two ends of the print head module frame 102 are respectively fixed on the movement side wall 3 and the movement right cover 4. The printhead module truss 1.02 and the movement truss, 202 are fixed to the fixed frame by screws. The invention may also have other embodiments, for example, the movement right cover 4 may be provided with a longer direct contact with the bottom plate 5, and a folded structure at the bottom end thereof, directly in the fold The structure is perforated, and the right cover 4 of the movement is fixed to the bottom plate 5 by screws. ,

The relative position between the frames of the "print head assembly" and the "rubber roller assembly" of the label printer of the present invention is fixed, and the entire movement module is not in a "cantilever" state. The entire movement frame consists of a steel plate fixedly attached to the machine's base plate and two aluminum alloy crosspieces (print head module truss and movement Rack), the structure is stable and reliable, and the accuracy is easy to guarantee. Simply adding a small amount of clearance between the "print head assembly" and the "rubber roll assembly" can solve the problem of loading consumables without affecting operation.
