Abstract
Description
Technical Field
[0001] This utility model relates to the field of thermal printer technology, specifically a thermal printer that reduces label paper waste. Background Technology
[0002] The print head is the core component of a thermal printer. It is responsible for converting electrical signals into heat energy, which heats the thermal paper (or thermal label) to make it develop color, thereby realizing the printing function. The thermal print head is the key printing component of the print head.
[0003] A common thermal printhead typically consists of a heating element, a ceramic substrate, a protective layer, and a drive circuit. The heating element is composed of thousands of tiny resistive points (pixels) arranged in one or more rows, with each resistive point corresponding to a printing pixel. The ceramic substrate is heat-resistant, has excellent thermal conductivity, high strength, and is not easily oxidized, making it suitable for long-term operation. The drive circuit controls the current flow, precisely activating the corresponding heating element according to the data signal. During printing, the label paper is placed in the paper tray, and the heating element is positioned on the ceramic substrate. Driven by the rollers in the printer, the label paper is fed along the ceramic substrate and printed by the thermal printhead. After use, the printer rewinds the excess paper back into the paper tray.
[0004] Under the above technical conditions, when the label paper is recycled, the label on the label paper comes into contact with the outer edge of the ceramic substrate. Since the outer edge of the ceramic substrate is relatively sharp, it is easy to scrape off the label paper, resulting in label damage and waste of label paper.
[0005] Based on this, the present invention designs a thermal printer that reduces label paper waste to solve the above problems. Utility Model Content
[0006] To achieve the above objectives, this utility model provides the following technical solution: a thermal printer that reduces label paper waste, comprising a printer body, a ceramic substrate disposed within the printer body, and a heating element disposed on the ceramic substrate. A fixing plate is fixedly disposed on the ceramic substrate, and a baffle is fixedly disposed on the fixing plate. The baffle is located above the ceramic substrate, with a portion of the baffle located outside the ceramic substrate. The baffle has an arc surface on the side facing the label paper.
[0007] By adopting the above technical solution, the baffle guides the label paper during paper collection, and the rounded surface prevents the baffle from scratching the label. When entering the paper tray, the contact between the label paper and the edge of the ceramic substrate is reduced, thereby reducing label damage.
[0008] Preferably, a guide plate is fixedly provided on the baffle.
[0009] By adopting the above technical solution, the guide plate moves the label paper, allowing the label paper to move along the baffle during winding, thereby reducing the contact between the label paper and the ceramic substrate.
[0010] Preferably, the fixing plate is made of aluminum.
[0011] By adopting the above technical solution, the aluminum mounting plate can improve heat dissipation.
[0012] Preferably, the baffle is provided with multiple clearance grooves.
[0013] By adopting the above technical solution, multiple clearance slots are provided to increase the heat dissipation area and further improve the heat dissipation effect.
[0014] Preferably, the fixing plate has multiple heat dissipation holes.
[0015] By adopting the above technical solution, the heat dissipation holes increase airflow and further improve the heat dissipation effect.
[0016] In summary, this application has the following beneficial technical effects: during paper collection, the baffle guides the label paper, and the arc surface prevents the baffle from scratching the label. When entering the paper tray, it reduces the contact between the label paper and the edge of the ceramic substrate, thereby reducing label damage. Attached Figure Description

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.
[0026] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.
[0027] Reference Figures 1-4 A thermal printer that reduces label paper waste includes a printer body 1, a ceramic substrate 2 disposed in the printer body 1, a heating element 3 disposed on the ceramic substrate 2, a mounting bracket 4 disposed on the printer body 1, a fixing plate 5 fixedly disposed on the ceramic substrate 2, a telescopic spring 6 fixedly connected between the mounting bracket 4 and the fixing plate 5, a guide block 7 disposed on the fixing plate 5, a guide groove 8 opened on the mounting bracket 4, and the guide block 7 located in the guide groove 8. When the rubber roller 9 of the printer body 1 contacts the label paper for printing, the telescopic spring 6 enables the rubber roller 9 to press against the heating element 3 for printing, making the printing more complete.
[0028] Reference Figures 1-4 A baffle 10 is fixedly installed on the fixing plate 5. The baffle 10 is integrally formed with the fixing plate 5 and the fixing plate 5 is made of aluminum. The baffle 10 is located above the ceramic substrate 2, and part of the baffle 10 is located outside the ceramic substrate 2. The baffle 10 has an arc surface facing the label paper. A guide plate 11 is fixedly installed on the baffle 10. The guide plate 11 is integrally formed with the baffle 10 and has an inclined surface. When the label paper is wound up, the guide plate 11 guides the label paper to move along the baffle 10 during winding, reducing the bending of the label paper and guiding the label paper through the baffle 10. The arc surface prevents the baffle 10 from scratching the label. When entering the paper tray, part of the baffle 10 is located outside the edge of the ceramic substrate 2, thereby reducing the contact between the label paper and the edge of the ceramic substrate 2 and reducing label damage.
[0029] Reference Figures 1-4The aluminum fixing plate 5 improves heat dissipation; the baffle 10 has multiple clearance grooves 12, which increase the heat dissipation area and further improve the heat dissipation effect; the fixing plate 5 has multiple heat dissipation holes 13, which increase airflow and further improve the heat dissipation effect. During paper output, the label paper needs to be pre-pulled to a position outside the machine body 1 with a portion of the label paper not containing a label, before the machine body 1 is driven to print.
[0030] Reference Figure 5 Another structure of the baffle 10 is that the baffle 10 is inclined upward on the side away from the fixed plate 5.
[0031] The implementation principle of this embodiment is as follows: when the label paper enters the paper tray, the baffle 10 is located outside the edge of the ceramic substrate 2, thereby reducing the contact between the label paper and the edge of the ceramic substrate 2, thereby reducing the edge of the ceramic substrate 2 from scraping off the label, thus achieving the effect of reducing label damage.
