Technical Field
[0001] The utility model belongs to the technical field of thermal transfer printing, and particularly relates to a print head support structure and a thermal transfer printer. Background Art
[0002] A thermal transfer printer is a contact printer with a relatively large pressure during printing. The print heads adopted on drum-type continuous thermal transfer printers generally have a support structure fixed on both sides. For the reciprocating printing method, the print head moves horizontally. When printing 1 PASS of the printing medium, it advances by the printing width of one print head and then continues to print. For this method, the support structure at both ends is complex, inconvenient to operate, difficult to replace the carbon ribbon, and the manufacturing cost is greatly increased at the same time. Summary of the Utility Model
[0003] In order to solve the above technical problems, one of the purposes of the utility model is to provide a print head support structure with a simple structure and convenient carbon ribbon replacement.

DETAILED DESCRIPTION OF THE EMBODIMENTS
[0029] The principles and features of the present invention will be described below with reference to the accompanying drawings. The examples given are only for explaining the present invention and are not intended to limit the scope of the present invention. In the following paragraphs, the present invention will be described more specifically by way of example with reference to the accompanying drawings. According to the following description and the claims, the advantages and features of the present invention will be more clearly described. It should be noted that the drawings are all in a very simplified form and use non-precise scales, and are only used to conveniently and clearly assist in explaining the purpose of the embodiments of the present invention.
[0030] Such as Figure 1 and Figure 2As shown in the figure, this embodiment provides a print head support structure, which includes a print head 1 and a two-dimensional moving frame 2. The two-dimensional moving frame 2 is located at the upper side of the print head 1. The print head 1 is horizontally arranged and installed at the driving end of the two-dimensional moving frame 2. The two-dimensional moving frame 2 is used to drive the print head 1 to make two-dimensional movement in the vertical plane. By directly installing the print head at the driving end of the two-dimensional moving frame, the entire print head is directly driven by the two-dimensional moving frame to move up and down and / or left and right. And the two-dimensional moving frame is only located at the upper side of one side of the print head, so that the other side area of the print head is relatively empty, and the operation of replacing the carbon ribbon for the print head can be conveniently carried out from this side.
[0031] As Figure 2 shown, in the above technical solution, the two-dimensional moving frame 2 includes a transverse moving member 21 and a longitudinal moving member 22. The transverse moving member 21 is horizontally arranged along the left-right direction. The longitudinal moving member 22 is installed at the driving end of the transverse moving member 21, and the driving end of the longitudinal moving member 22 faces downward. The print head 1 is horizontally installed at the driving end of the longitudinal moving member 22. In this way, the transverse moving member drives the longitudinal moving member to move left and right, and the longitudinal moving member drives the print head to move up and down. At this time, for the print head, it is jointly driven by the transverse moving member and the longitudinal moving member to make two-dimensional movement in the vertical plane.
[0032] As Figure 1 shown, in the above technical solution, a plurality of the longitudinal moving members 22 and the print heads 1 are provided, and the plurality of longitudinal moving members 22 and the plurality of print heads 1 correspond one by one. The plurality of longitudinal moving members 22 are spaced apart along the left-right direction and are all installed at the driving end of the transverse moving member 21. Each print head 1 is installed at the driving end of the corresponding longitudinal moving member 22. In this way, the plurality of print heads can move left and right synchronously, but each print head can move up and down independently.
[0033] As Figure 1 and Figure 2As shown, in the above technical solution, the lateral moving member 21 includes a moving trolley 211 and a trolley beam 212. The trolley beam 212 is horizontally arranged in the left - right direction. The moving trolley 211 is installed on the trolley beam 212 and can move left and right along the trolley beam 212. The moving trolley 211 constitutes the driving end of the lateral moving member 21. Its structure is simple, and the moving trolley uses the trolley beam as a carrier and can move flexibly left and right on the trolley beam. In this embodiment, the trolley beam is equivalent to a slide rail, and the moving trolley is equivalent to a slider arranged on the trolley beam and slidably connected to the slide rail. Moreover, a driving member is provided on the moving trolley, and the driving member is in transmission connection with the trolley beam. The driving member drives the moving trolley to move left and right on the trolley beam. The driving member can be a screw linear driving mechanism, a belt linear driving mechanism or a rack - and - pinion linear driving mechanism, which all belong to the prior art and will not be elaborated here.
[0034] As Figure 2 and Figure 3 shown, in the above technical solution, the longitudinal moving member 22 includes a mounting arm 221, a movable arm 222 and a telescopic cylinder 223. Both the mounting arm 221 and the movable arm 222 are horizontally arranged in the front - rear direction. One end of the mounting arm 221 is connected to the driving end of the lateral moving member 21. The movable arm 222 is located below the mounting arm 221. The telescopic cylinder 223 is vertically installed at the lower end of the mounting arm 221, and its telescopic end faces downward and is perpendicularly connected to the middle of the upper end of the movable arm 222. The movable arm 222 constitutes the driving end of the longitudinal moving member 22. Its structure is simple, and the movable arm is driven by the telescopic cylinder to move up and down. In this embodiment, the telescopic cylinder is preferably a telescopic air cylinder, especially a slide - table air cylinder. Of course, the telescopic cylinder can be embedded in the mounting arm, making the volume of the entire longitudinal moving member more compact and small.
[0035] As Figure 2 and Figure 3 shown, in the above technical solution, the longitudinal moving member 22 further includes a guide rod 224. The guide rod 224 is vertically arranged at the upper end of the movable arm 222, and the guide rod 224 is vertically slidably connected to the mounting arm 221. By setting the guide rod, the movable arm can maintain better stability when moving up and down.
[0036] As Figure 2 and Figure 3 shown, in the above technical solution, the longitudinal moving member 22 has two guide rods 224, and the two guide rods 224 are spaced apart along the length direction of the movable arm 222. The telescopic cylinder 223 is located between the two guide rods 224, so that the stability of the movable arm when moving up and down is better.
[0037] As shown Figure 3 As shown, a sliding hole 2211 for the upper end of the guiding rod 224 to penetrate is recessed at the lower end of the mounting arm 221 in the above technical solution (the sliding hole can be a through hole or a blind hole), so that the sliding connection between the guiding rod and the mounting arm is more convenient.
[0038] As shown Figure 2 As shown, a plurality of heat dissipation fans 11 are installed at intervals along the length direction of the upper end of the print head 1 in the above technical solution, so that the print head can be sufficiently cooled by the heat dissipation fans.
