Description

Technical Field

[0001] The utility model belongs to the technical field of printers, and particularly relates to a printing head heat dissipation structure of a wide-format label printer. Background Technique

[0002] The thermal transfer label printer is a common printing device. It transfers patterns or texts to labels or other materials through heat and pressure. The background of this printing technology can be traced back several centuries, but its modern form mainly developed with the progress of technology in the second half of the 20th century. The printing head of the thermal transfer label printer is a heat-generating component, and currently, the printing heads on the market are placed in the machine.

[0003] For some existing printers, during use, they cannot effectively discharge the heat generated by the printing head outside the machine, resulting in that after printing about 20 sheets continuously normally, it may prompt that the printing head temperature is too high and printing cannot continue. The strength of its printing head heat sink is insufficient, which easily affects the use effect and work efficiency. Content of the Utility Model

[0004] The technical problem to be solved by the utility model is to overcome the existing defects and provide a printing head heat dissipation structure of a wide-format label printer to solve the problem that for some existing printers during use, they cannot effectively discharge the heat generated by the printing head outside the machine, resulting in that after printing about 20 sheets continuously normally, it may prompt that the printing head temperature is too high and printing cannot continue, and the strength of its printing head heat sink is insufficient, which easily affects the use effect and work efficiency as mentioned in the above background technique.

[0005] To achieve the above object, the utility model provides the following technical solution: A printing head heat dissipation structure of a wide-format label printer, including a printer housing, plastic linings are symmetrically and fixedly connected inside the printer housing, a printing head bracket is fixedly connected to one side of the printer housing close to the plastic linings, a spring is fixedly connected to one side of the printing head bracket, one end of the spring is fixedly connected to an aluminum heat sink, and a sheet metal heat sink is fixedly connected to one side of the aluminum heat sink.

[0006] Preferably, the back of the aluminum heat sink is set in a scale shape.

[0007] Preferably, a plurality of plastic linings are provided.

[0008] Preferably, a heat dissipation port is provided on one side of the printer housing close to the plastic linings.

[0009] Preferably, heat dissipation holes are fixedly connected inside the heat dissipation port.

[0010] Preferably, a rubber roller fork is fixedly connected to one side of the printer housing close to the sheet metal heat sink.

[0011] Preferably, dust-proof plates are symmetrically and fixedly connected to one side of the outer part of the printer housing close to the heat dissipation holes.

[0012] Preferably, a plurality of dust-proof plates are provided.

[0013] Compared with the prior art, the present utility model provides a print head heat dissipation structure for a wide-width label printer, having the following beneficial effects:

[0014] 1. By providing the printer housing, the heat dissipation structure involved in the present utility model includes a print head assembly and a housing heat dissipation hole. The heat dissipation principle is that the heat generated by the print head is conducted to the aluminum heat sink through the print head. The aluminum heat sink is responsible for absorbing the heat generated by the print head. The shape of the back of the aluminum heat sink is designed in a scale shape, so that the heat dissipation area of the heat sink will increase a lot. Finally, the absorbed heat is discharged outside the machine through the heat dissipation hole. The print head assembly is composed of a printer housing, a plastic lining, a print head bracket, a spring, a rubber roller fork, a sheet metal heat sink, an aluminum heat sink and a heat dissipation hole. The heat sink is composed of a sheet metal heat sink and an aluminum heat sink. A combined heat sink is adopted, and a sheet metal part or an aluminum extrusion sheet on the market is not directly used. If only a sheet metal part is used as the heat sink, the heat dissipation is not good, because the sheet metal part is made of stainless steel or galvanized sheet, and the heat dissipation of these two materials is far inferior to that of aluminum, and the heat dissipation area cannot be made into many scale shapes like aluminum. If only an aluminum extrusion sheet is used, the stiffness of aluminum is far less than that of stainless steel or galvanized sheet, and a sufficient thickness needs to be made to be equivalent to the stiffness of stainless steel or galvanized sheet. Insufficient stiffness will cause the heat sink to deform and result in unclear printing.

[0015] 2. By providing the heat dissipation hole, heat dissipation is facilitated.

[0016] Parts not involved in this device are the same as or can be implemented using the prior art. The structure of the present utility model is scientific and reasonable, safe and convenient to use, and provides great help to people. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0024] Please refer to Figures 1-4 , the present invention provides a technical solution: a print head heat dissipation structure for a wide-format label printer, including a printer housing 1. Plastic inner linings 2 are symmetrically and fixedly connected inside the printer housing 1. A print head support 3 is fixedly connected to one side inside the printer housing 1 close to the plastic inner lining 2. A spring 4 is fixedly connected to one side of the print head support 3. One end of the spring 4 is fixedly connected to an aluminum heat sink 7. A sheet metal heat sink 6 is fixedly connected to one side of the aluminum heat sink 7. The involved heat dissipation structure includes a print head assembly and a housing heat dissipation hole. The heat dissipation principle is that the heat generated by the print head is conducted to the aluminum heat sink 7 through the print head. The aluminum heat sink 7 is responsible for absorbing the heat generated by the print head. The shape of the back of the aluminum heat sink 7 is designed as a scale shape 9, so that the heat dissipation area of the heat sink will increase a lot. Finally, the absorbed heat is discharged outside the machine through the heat dissipation holes 8. The print head assembly is composed of a printer housing 1, a plastic inner lining 2, a print head support 3, a spring 4, a rubber roller fork 5, a sheet metal heat sink 6, an aluminum heat sink 7, and heat dissipation holes 8. The heat sink is composed of a sheet metal heat sink 6 and an aluminum heat sink 7. A combined heat sink is adopted, and directly using sheet metal parts or aluminum extrusion sheets on the market is not used. If only sheet metal parts are used as the heat sink, the heat dissipation is not good, because the sheet metal parts are made of stainless steel or galvanized plates, and the heat dissipation of these two materials is far inferior to that of aluminum, and the heat dissipation area cannot be made into many scales like aluminum. If only aluminum extrusion sheets are used, the stiffness of aluminum is far less than that of stainless steel or galvanized plates, and sufficient thickness needs to be made to be equivalent to the stiffness of stainless steel or galvanized plates. Insufficient stiffness will cause the heat sink to deform and result in unclear printing.

[0025] In the present utility model, preferably, the back surface of the aluminum heat sink 7 is provided with a scale shape 9.

[0026] In the present utility model, preferably, a plurality of plastic linings 2 are provided.

[0027] In the present utility model, preferably, a heat dissipation port 10 is provided on one side of the printer housing 1 close to the plastic lining 2.

[0028] In the present utility model, preferably, a heat dissipation hole 8 is fixedly connected inside the heat dissipation port 10 to facilitate heat dissipation.

[0029] In the present utility model, preferably, a rubber roller fork 5 is fixedly connected to one side of the printer housing 1 close to the sheet metal heat sink 6.

[0030] In the present utility model, preferably, dust-proof plates 11 are symmetrically and fixedly connected to one side of the printer housing 1 outside close to the heat dissipation holes 8.

[0031] In the present utility model, preferably, a plurality of dust-proof plates 11 are provided.

[0032] The working principle and usage process of the present utility model: When in use, by setting the printer housing 1, the involved heat dissipation structure includes a print head assembly and a housing heat dissipation hole. The heat dissipation principle is that the heat generated by the print head is conducted to the aluminum heat sink 7 through the print head. The aluminum heat sink 7 is responsible for absorbing the heat generated by the print head. The back surface of the aluminum heat sink 7 is designed in a scale shape 9, so that the heat dissipation area of the heat sink will increase a lot. Finally, the absorbed heat is discharged outside the machine through the heat dissipation holes 8. The print head assembly is composed of the printer housing 1, the plastic lining 2, the print head bracket 3, the spring 4, the rubber roller fork 5, the sheet metal heat sink 6, the aluminum heat sink 7, and the heat dissipation holes 8. The heat sink is composed of the sheet metal heat sink 6 and the aluminum heat sink 7. A combined heat sink is adopted, and the sheet metal parts or aluminum extrusion sheets on the market are not directly used. If only sheet metal parts are used as the heat sink, the heat dissipation is not good, because the sheet metal parts are made of stainless steel or galvanized sheet, and the heat dissipation of these two materials is far inferior to that of aluminum, and the heat dissipation area cannot be made into many scales like aluminum. If only aluminum extrusion sheets are used, the stiffness of aluminum is much lower than that of stainless steel or galvanized sheet, and sufficient thickness needs to be made to be equivalent to the stiffness of stainless steel or galvanized sheet. Insufficient stiffness will cause the heat sink to deform and result in unclear printing. By setting the heat dissipation holes 8, heat dissipation is facilitated.

[0033] Although the embodiments of the present utility model have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present utility model. The scope of the present utility model is defined by the appended claims and their equivalents.
