Description

Technical Field

[0001] This utility model relates to the field of intelligent terminal equipment technology, and in particular to a label printer with a replaceable printhead. Background Technology

[0002] Label printers, also known as smart label printers or portable smart label printers, use thermal or thermal transfer technology to print information such as text, images, or barcodes directly onto labels. For example, in the logistics industry, they are used to print information such as batch number, quantity, and weight of goods to facilitate management and tracking; in the medical industry, they are used to print information such as production date, shelf life, and dosage of medicines to help patients use medications correctly. When the internal printhead is damaged or worn out, the user needs to replace it with a new one.

[0003] In existing printers, the print head is usually installed and fixed with screws, which not only requires tools but also makes it inconvenient for users to operate due to the relatively narrow space inside the printer. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies, which mostly rely on screws for installation and fixation, requiring tools and being inconvenient for users due to the limited internal space of the printer. Therefore, this invention proposes a label printer with a replaceable printhead.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A label printer with a replaceable printhead includes a printer body and a printhead, wherein a bracket is provided inside the printer body and the printhead is installed inside the bracket;

[0007] An installation mechanism is used to install the printhead into a bracket. The installation mechanism is located inside the bracket and includes a placement frame and a mounting plate. The placement frame is fixedly installed inside the bracket, and the mounting plate is located at the bottom of the placement frame. L-shaped plates are fixedly installed on both sides of the bottom of the mounting plate. The printhead is inserted between the bottom of the mounting plate and the bottom inner wall of the L-shaped plates. A movable plate is slidably installed on the top of the placement frame, and an insertion block is fixedly installed on the top of the mounting plate. A positioning hole is opened on the top of the placement frame, and the top of the insertion block passes through the positioning hole. An insertion hole is opened on one side of the insertion block, and one end of the movable plate passes through the insertion hole.

[0008] In one possible design, fixing rings are fixedly installed on both sides of the top of the placement rack, side plates are fixedly installed on both sides of the movable plate, and a sliding rod is fixedly installed on one side of the side plate. The two fixing rings are slidably sleeved on the outer walls of the two sliding rods, and a tension spring is sleeved on the outer wall of the sliding rod, with the two ends of the tension spring fixedly installed on one side of the side plate and one side of the fixing ring, respectively.

[0009] In one possible design, a fixed side clamp is fixedly installed on one side of the bottom of the placement rack, and a movable side clamp is fixedly installed on one end of the movable plate. The print head and the mounting plate are both located between the fixed side clamp and the movable side clamp.

[0010] In one possible design, the mounting mechanism further includes a rotating cover, one end of which is rotatably mounted on one side of the top of the movable plate. A locking plate is fixedly mounted on one side of the bottom of the rotating cover. A slot is provided on the top of the movable plate, and a hole is provided on the top of the insert block. The hole and the insert hole are connected. The hole and the slot are connected. The locking plate cooperates with the slot and the hole.

[0011] In one possible design, a concave surface is provided on one side of the fixed side clamp, and the interface end of the print head mates with the concave surface.

[0012] In one possible design, limit rods are fixedly installed on both sides of the top of the mounting plate, and limit holes are opened on both sides of the top of the placement frame, with the two limit rods cooperating with the two limit holes respectively.

[0013] In this application, during actual use, simply insert the printhead between the bottom of the mounting plate and the inner wall of the L-shaped plate. Then, insert the corresponding connecting harness to the printhead interface. After moving the movable plate, the mounting plate can be placed at the bottom of the placement frame, and the top insert block is inserted through the positioning hole to the top of the placement frame. At the same time, the limiting rod is also inserted into the corresponding limiting hole. Then, the movable plate is reset by the tension spring, so that one end of the movable plate passes through the insertion hole, thereby fixing the mounting plate at the bottom of the placement frame. When the movable plate moves, it will drive the movable side clamping plate to move. The movable side clamping plate will cooperate with the fixed side clamping plate to clamp and fix the printhead and mounting plate at the bottom of the placement frame, thereby improving stability. Finally, rotate the cover so that the bottom carding plate is locked into the card hole and card slot, thereby limiting the movable plate and finally realizing the installation of the printhead. Conversely, the reverse operation can be performed to disassemble and replace it.

[0014] In this utility model, the replaceable printhead label printer can, through the moving plate of the mounting mechanism, fix the mounting plate with the printhead while clamping the mounting plate and the printhead together, thereby improving the stability of the installation. Conversely, by directly moving the moving plate, the fixation of the two can be released, making it convenient for disassembly and replacement.

[0015] In this utility model, the replaceable printhead label printer can limit the movement plate used to fix the printhead by means of the rotating cover of the mounting mechanism, thereby increasing the stability of the movement plate during use and avoiding the possibility of displacement.

[0016] In this invention, the installation of the printhead is simple and easy. Users can easily remove the old printhead and install the new one, which not only improves the replacement efficiency but also reduces the difficulty of operation. It also allows for printhead replacement without tools and avoids the problem of limited internal space and inconvenient operation. Attached Figure Description
