Description

Technical Field

[0001] This utility model relates to the field of barcode printer technology, specifically a barcode printer with an easy-to-replace printhead. Background Technology

[0002] A barcode printer is a specialized printer. The biggest difference between a barcode printer and a regular printer is that barcode printers use heat as the printing medium and a ribbon (or thermal paper) to complete the printing. The biggest advantage of this printing method over regular printing is that it can achieve continuous high-speed printing without supervision.

[0003] A barcode printer described in patent publication number CN 220298137 U uses a combination of a motor, transmission assembly, guide assembly, and paper guide channel to move a gate up and down repeatedly along the guide assembly. The shearing action between the gate and the paper guide channel cuts the printing paper. The structure is simple and the operation is stable, avoiding the problems caused by manual tearing. However, because the printhead of this type of printer is in a state of heat for a long time during operation, the printhead is prone to wear and tear, and the replacement of the printhead of the above-mentioned device is relatively difficult, which affects the working efficiency of this type of printer.

[0004] Therefore, barcode printers that allow for easy printhead replacement are now available, eliminating the drawbacks of existing devices. Utility Model Content

[0005] The purpose of this invention is to provide a barcode printer with an easy-to-replace printhead, in order to solve the problems in the background art.

A first locking mechanism 700 is provided between the flip-out housing 900 and the housing 100. With these features, the printing assembly operates and prints under the drive of the drive structure 200, and the flip-out housing 900 can be opened and closed via the first locking mechanism 700 for convenient maintenance of the internal components.

[0030] In one embodiment, such as Figure 3 As shown, the printing assembly 400 includes a ribbon supply shaft 401 and a ribbon recovery shaft 402. The ribbon recovery shaft 402 is located in the middle of the right side of the partition 300. The ribbon supply shaft 401 is located on one side of the ribbon recovery shaft 402. A printing head component 600 is located below the other side of the ribbon recovery shaft 402. A label supply shaft 500 is located below the other side of the ribbon supply shaft 401. With the above arrangement, the ribbon extends from the ribbon supply shaft 401, passes through the printing head component 600, and is wound on the ribbon recovery shaft 402. The label tape extends from the label supply shaft 500, is printed in the printing head component 600, and is then conveyed out of the device.

[0031] In one embodiment, such as Figure 6 As shown, the drive structure 200 includes a first drive motor 201 and a second drive motor 202. The output end of the first drive motor 201 is connected to the input end of the ribbon take-up shaft 402, and the output end of the second drive motor 202 is connected to the printhead component 600. With the above arrangement, the first drive motor 201 drives the ribbon take-up shaft 402 to operate, and the second drive motor 202 drives the printhead component 600 to operate.

[0032] In one embodiment, such as Figure 8 As shown, the label supply shaft 500 includes a fixed housing 501, which is fixedly connected to the partition plate 300. The upper end of the fixed housing 501 is provided with a sliding groove 502, and a limiting post 503 is slidably provided on the sliding groove 502. A slider 504 is fixedly connected to the lower end of the limiting post 503. The slider 504 is connected to one end of the interior of the fixed housing 501 through a limiting spring 505. With the above settings, the limiting post 503 can be pulled to a distance suitable for the label size, and at the same time, the limiting post 503 clamps the label roller under the action of the limiting spring 505.

[0033] In one embodiment, such as Figure 5As shown, the printhead component 600 includes a lower mounting body 601 and an upper mounting body 602. The lower mounting body 601 is connected to the housing 100. One end of the lower mounting body 601 is provided with a guide rod 603, and the other end of the lower mounting body 601 is provided with an active roller 604 and a passive roller 605. The input end of the active roller 604 is connected to the input end of the second drive motor 202. A detachable thermal printhead 606 is inserted into the upper mounting body 602. A movable cover plate 607 is rotatably provided above the upper mounting body 602. The movable cover plate 607 and the upper mounting body 602 are fixed together by a second locking mechanism 800. With the above configuration, the movable cover plate 607 can be easily opened through the second locking mechanism 800 to replace the detachable thermal printhead 606. The label tape entering the component will be guided in by the guide rod 603 and then transported out of the printer by the active roller 604.

[0034] In one embodiment, such as Figure 7 As shown, the first locking mechanism 700 includes an equilateral triangular locking block 701 and an inverted triangular locking block 702. The equilateral triangular locking block 701 is mirror-mounted inside the upper shell wall of the housing 100. One end of the equilateral triangular locking block 701 is fixedly connected to a rigid block 703. A button 705 is provided at the upper middle part of the rigid block 703. Return springs 704 are provided on the lower sides of both ends of the rigid block 703. The inverted triangular locking block 702 is located on the flip-out housing 900 at a position opposite to the equilateral triangular locking block 701. With the above arrangement, the flip-out housing 900 can be locked to the equilateral triangular locking block 701 on the housing 100 by the inverted triangular locking block 702, which is convenient for fixing. When unlocking, simply pressing the button 705 can release the equilateral triangular locking block 701 and the inverted triangular locking block 702.

[0035] In one embodiment, as shown in Figure 5, the second locking mechanism 800 includes a square locking block 801 and a locking shell 802. The square locking block 801 is mirror-displayed on the right side of the upper mounting body 602, and the locking shell 802 is rotatably disposed on the movable cover plate 607 at a position opposite to the square locking block 801. With the above arrangement, when the movable cover plate 607 is closed, the locking shell 802 can be rotated to cover the square locking block 801, locking the movable cover plate 607 and the upper mounting body 602, which is simple and quick.

[0036] Example 2

[0037] In one embodiment, the flip-out housing 900 is provided with an observation window, which allows the operator to easily observe the internal condition of the printer and react accordingly.
