Description

Technical Field

[0001] The utility model relates to the technical field of constant temperature control of ink circuits of inkjet printers, in particular to a constant temperature control device for ink circuits of inkjet printers. Background Art

[0002] A UV printer is an inkjet printer, in which a print head arranged opposite to a platen moves back and forth relative to a print medium placed on the platen, and ink is ejected from the print head to print on the print medium. When working in this way, ink is ejected from the print head at a constant temperature to ensure the quality of printing, and the sprayed picture is clear. At present, the printer ink cartridges used have good thermal insulation effects, which effectively reduce the drop in ink temperature during use. However, during use, the ink will flow from the ink cartridge to the print head through the pipeline. During the circulation process, the temperature will be lost, which will cause the temperature of the ink to drop (and the temperature drop rate will be affected by the environment in which the printer is located), thereby affecting the quality of the printed picture.

The purpose of the accompanying drawings is to supplement the description of the text part of the specification with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the utility model, but it cannot be understood as a limitation on the protection scope of the utility model.

[0020] Reference Figure 1-4 The utility model embodiment is a constant temperature control device for ink path of inkjet printer, which comprises: an ink cartridge 1, the ink cartridge 1 is connected with an ink tube 2, and a constant temperature heating device 3 for heating ink is clamped and fixed on the outer wall of the tail end of the ink tube 2;

[0021] The constant temperature heating device 3 includes a limit groove block 309 and two clamping cylinders 301 symmetrically arranged on the left and right. The top of the clamping cylinder 301 is provided with a guide arc edge 308 to guide the clamped ink tube 2. When the two clamping cylinders 301 are combined, the inner wall is in contact with the outer surface of the ink tube 2. A heating chamber 304 is opened inside the clamping cylinder 301. The inner wall of the heating chamber 304 away from the copper sheet 306 is provided with a heat insulation layer 307 to avoid scalding the staff. The heating coils 305 are evenly arranged in the cavity of the heating chamber 304. The heating coils 305 are electrically connected to the external controller. The clamping surface of 301 is set as a copper sheet 306 to improve the heat conduction efficiency. A limiting slide 302 is provided at the bottom end of the clamping cylinder 301. Two sliding holes 303 are opened on the limiting slide 302. The side walls of the limiting slide 302 are slidably connected to the inner wall of the limiting groove block 309. Two sliding rods 310 are fixed between the front and rear inner walls of the limiting groove block 309. The side walls of the sliding rod 310 are slidably connected to the inner walls of the sliding holes 303. A spring 311 is provided between the inner wall of the limiting groove block 309 and the opposite surface of the limiting slide 302, and the spring 311 is wound around the outer wall of the sliding rod 310. When the ink in the ink tube 2 is heated by the heating coil 305, the copper sheet 306, the clamping tube 301 and the heating chamber 304, the constant temperature heating device 3 is clamped and fixed at the end of the ink tube 2, and the two clamping tubes 301 are combined to fully surround the outer wall of the ink tube 2. The heating coil 305 is started by the controller to heat, and the temperature is guided from the copper sheet 306 to the outer wall of the ink tube 2, so as to heat the ink in the ink tube 2 to keep it at a constant temperature and improve the inkjet efficiency. The positioning slide plate 302, the sliding hole 303, the limiting groove block 309, the sliding rod 310, the spring 311, and the guide arc edge 308 are used to clamp the ink tube 2. The ink tube 2 only needs to be placed on the gap between the two guide arc edges 308 and pressed downward. At this time, the spring 311 contracts, and the two clamping cylinders 301 open and close. When the ink tube 2 slides into the inner wall of the clamping cylinder 301, the spring 311 stretches and resets, pushing the two clamping cylinders 301 to merge, and the ink tube 2 is wrapped.
