Description

Technical Field

[0001] The present invention relates to the field of label printers, in particular to a label printer and an anti-jamming component and a print head assembly thereof. Background Art

[0002] Existing printers are widely used in people's daily lives, such as price tags in supermarkets and label printers for printing personalized labels such as dates and logos at home. Existing thermal printers use a semiconductor heating element, such as a ceramic plate, installed in the print head. This heats the ceramic plate and contacts thermal paper to print the desired pattern. During printing, the paper is positioned between the ceramic plate and the rubber roller, which drives the paper. The printing surface of the paper can be considered a smooth plane. The contact surface between the paper and the rubber roller and the contact surface between the ceramic plate and the paper must be parallel to each other to produce a clear pattern on the paper.

[0003] When used to print die-cut labels, the right-angled edge at the top of the print head ceramic plate will cause the die-cut label to be scraped up when it is unrolled, causing the die-cut label to be peeled off from the base paper. The peeled die-cut surface paper will be squeezed and stacked between the rubber roller and the print head ceramic plate, eventually causing the rubber roller to be blocked, making it impossible to effectively unroll the paper and print effectively. This is the main reason why label printers on the market do not have a paper rewind function, resulting in waste of the exposed portion of the label paper.

[0004] As can be seen, the existing label printers mentioned above still have inconveniences and defects in their structure, methods, and use, and are in urgent need of further improvement. Creating a new label printer, along with its anti-jam component and printhead assembly, that can eliminate paper jams and waste while also saving costs and simplifying operation has become a pressing need in the industry. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to provide an anti-jamming component for a label printer, which can solve the problem of paper returning without jamming and avoid label waste, save costs, and is easy to operate, thereby overcoming the shortcomings of existing label printers.

[0006] In order to solve the above technical problems, the present invention provides an anti-stuck component for a label printer, which is arranged on the paper outlet side of the print head ceramic plate inside the label printer, and has an extension plate protruding from the top of the print head ceramic plate on the label paper feeding channel, and the edge of the extension plate is arranged to be a chamfered structure.

[0007] As a further improvement, the distance that the rounded corner structure protrudes from the top of the print head ceramic plate on the label paper feeding path is less than 1.0 mm.

[0008] As a further improvement, the distance that the rounded corner structure protrudes from the top of the print head ceramic plate on the label paper feeding path is 0.1-0.5 mm.

[0009] As a further improvement, the anti-stuck component also includes a fixed plate connected to the extension plate nearly perpendicularly, and fixed legs are provided at both ends of the extension plate and the fixed plate, and the fixed legs are connected to the print head assembly.

[0010] As a further improvement, a plurality of vertical reinforcing ribs are provided between the fixed plate and the extension plate.

[0011] As a further improvement, the fixing plate is provided with a notch for the label paper detection mechanism to pass through.

[0012] As another improvement of the present invention, the present invention provides a print head assembly, including a bracket, and a print head substrate, a print head ceramic plate and a leaf spring arranged on the bracket, one side of the print head substrate is connected to the print head ceramic plate, and the other side is connected to the leaf spring, the leaf spring is arranged on the side wall of the bracket, and the above-mentioned anti-stuck component is fixed on the paper outlet side of the print head substrate and the print head ceramic plate.

[0013] As a further improvement, the length of the extension plate of the anti-stuck component is equal to the length of the ceramic plate of the print head.

[0014] As another improvement of the present invention, the present invention also provides a label printer including the above-mentioned print head assembly.

[0015] After adopting such a design, the present invention has at least the following advantages:

[0016] The anti-stuck component of the label printer of the present invention is arranged on the paper outlet side of the print head ceramic plate and protrudes more than the top of the print head ceramic plate. The rounded corner structure can cleverly avoid the defect that the die-cut label paper is scraped off during the paper feeding and feeding process, thereby affecting normal printing. On the basis of normal paper feeding, the technical effect of greatly improving the paper feeding success rate is achieved, solving the problem of waste of exposed labels after installing label consumables, saving costs and improving user experience.

[0020] Figure 3 It is a schematic diagram of the longitudinal section structure of the label printer of the present invention.

[0021] Figure 4 It is an enlarged schematic diagram of the structure of the print head assembly and the rubber roller in the label printer of the present invention. DETAILED DESCRIPTION

[0022] Refer to the attached Figure 1 and 3 As shown, the print head assembly and electric drive mechanism used in the label printer of this embodiment are mature products in the existing market. They include a print head ceramic plate 1, a print head base plate 2, a leaf spring 3, a print head bracket 4, a motor 5, and a gear transmission mechanism 6. One side of the print head base plate 2 is connected to the print head ceramic plate 1, and the other side is connected to the leaf spring 3. The leaf spring 3 is arranged on the side wall of the print head bracket 4. The leaf spring 3 provides thrust for the print head ceramic plate 1, so that the print head ceramic plate 1 can be closely attached to the label paper 10 and parallel to the rubber roller 7. The label paper 10 is located between the print head ceramic plate 1 and the rubber roller 7. The motor 5 drives the gear transmission mechanism 6 to rotate, which in turn drives the rubber roller 7 to rotate. The rubber roller 7 can move the label paper 10 through friction with the label paper 10, and the print head assembly can simultaneously achieve label printing.

[0023] In a preferred embodiment, the label printer includes an anti-stuck member 8 arranged on the paper outlet side of the print head ceramic plate 1, as shown in the attached Figure 2 The edge of the anti-stuck component 8 adjacent to the top of the print head ceramic plate 1 is configured as a rounded structure, and the rounded structure protrudes from the top of the print head ceramic plate 1 on the label paper feeding path.

[0024] Better, as attached Figure 4 As shown, the distance that the chamfered structure protrudes from the top of the print head ceramic plate on the label paper feeding channel is 0.1-1.0mm, preferably 0.1-0.3mm. In this way, when the label paper is retracted, since the anti-stuck component protrudes from the top of the print head ceramic plate, the die-cut label paper can be retracted smoothly, and the die-cut label on the label paper is prevented from being scraped off by the right-angled top of the print head ceramic plate 1 during retraction, causing the die-cut label to be peeled off from the base paper, resulting in obstruction of paper retraction and inability to print normally. In addition, the setting of the chamfered structure of the anti-stuck component allows the die-cut label paper to be fed smoothly, and the die-cut label surface paper will not be peeled off, thus achieving smooth printing and outputting. The setting of the anti-stuck component 8 greatly improves the success rate of paper retraction of the label printer, completely solves the problem that the existing label printer cannot retract paper, and allows the unprinted labels exposed outside the machine to be smoothly returned to the inside of the machine, reducing label waste.

[0025] Specifically, the anti-stuck component 8 of this embodiment includes a fixed plate 81 with the same length as the print head substrate 2 and an extension plate 82 perpendicular to the fixed plate 81, wherein the extension plate 82 extends to the upper end of the print head ceramic plate 1, and the edge of the extension plate 82 is set to a chamfered structure.

[0026] A plurality of vertical reinforcing ribs 83 are provided between the fixing plate 81 and the extension plate 82 to ensure the stability of the anti-jamming member. The extension plate 82 and the fixing plate 81 are provided with fixing legs 84 at both ends. The fixing legs 84 are inserted into the print head assembly to achieve the fixing of the anti-jamming member.

[0027] In order to achieve miniaturization of the label printer, the fixing plate 81 of the anti-stuck member 8 in this embodiment is further provided with an escape opening 85 for the photoelectric passage of the label paper detection mechanism, making the internal structure of the printer more compact and reasonable.

[0028] The present invention uses the anti-stuck component on the print head assembly and applies it to the label printer, which can cleverly solve the problem that the existing label printer cannot realize the paper rewind function, truly solve the problem of the return of exposed unprinted labels, avoid label waste, save costs, and improve user experience.
