Abstract
Description
Technical Field
[0001] This utility model relates to the field of printer technology, and in particular to a guide rod slider module for printers. Background Technology
[0002] In the printhead moving mechanism of a printer, the guide rod slider module is a key component for achieving precise linear transmission. However, in existing printer guide rod slider modules, the slider and guide rod are mostly integrated or have complex connection structures. When the slider or guide rail needs maintenance or replacement, disassembly and reassembly are difficult, time-consuming, and labor-intensive, increasing maintenance costs and downtime. On the other hand, the internal wiring of the printer is complex. If the wiring harness becomes entangled or interferes with the moving slider, it will affect the normal operation of the slider, or even damage the wiring harness and slider structure, reducing the stability and lifespan of the printer. Therefore, in order to further meet the needs of printers for high efficiency, stability, and easy maintenance, it is necessary to provide a new modular technology solution. Utility Model Content
[0003] The purpose of this utility model is to overcome the shortcomings of the prior art and provide a new type of guide rod slider module for printers, which is easy to separate from the guide rod slider, convenient for maintenance and replacement, and is equipped with an isolation mechanism.

The groove surfaces of the upper and lower rows of V-shaped guide rods face each other, and a detachable slider is sandwiched between them. The front part of the slider is used to mount the print head, and the rear part is connected to a timing belt. A timing pulley is wound around each of the left and right ends of the timing belt. One of the two timing pulleys is connected to the drive shaft of a stepper motor.
[0006] The two rows of V-shaped guide rods are synchronously fixed or rotated.
[0007] Furthermore, mounting blocks are connected to the left and right ends of the internal mounting plate. The mounting blocks are connected to the two ends of the V-shaped guide rods via bearing turntables. A synchronization mechanism is provided between the two rows of V-shaped guide rods. The synchronization mechanism includes two toothed plates that are symmetrically arranged and meshing. The two toothed plates are connected to the two rows of V-shaped guide rods one-to-one and rotate synchronously.
[0008] Furthermore, the slider contacts the grooved surface of the V-shaped guide rod via a rolling element, which is either a ball or a roller.
[0009] Furthermore, one end of one of the two rows of V-shaped guide rods is connected to a rotating handle, and the outer end of the rotating handle is fixed to the mounting block by screws.
[0010] Furthermore, the rear part of the slider is provided with a timing belt fixing groove and a timing belt passage groove in the vertical direction, and the timing belt is arranged parallel to the matching V-shaped guide rod.
[0011] Furthermore, the internal mounting plate is made of galvanized sheet metal with a thickness of 1.2mm to 1.8mm, bent into shape, and has mounting holes at both ends.
[0012] Furthermore, an inclined baffle plate is provided above the V-shaped guide rod, and the left and right ends of the baffle plate are inserted into slots provided on the inner side of the mounting block.
[0013] Furthermore, the front and rear parts of the slider are separable and connected by screws or magnetic blocks.
[0014] Furthermore, the upper and lower ends of the front part of the slider are provided with V-shaped protrusions and are engaged between two rows of paired V-shaped guide rods.
[0015] The beneficial effects of adopting the technical solution of this utility model are as follows:
[0016] 1. The printer guide rod slider module of this utility model is equipped with a rotatable V-shaped guide rod, which makes it easy to separate the guide rod and slider and facilitates maintenance and replacement.
[0017] 2. The printer guide rod slider module of this utility model is equipped with a baffle plate, which effectively prevents the internal wiring harness of the printer from getting tangled or interfering with the moving slider, and ensures the normal operation of the slider.

Detailed Implementation
[0026] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention. The present invention is described in detail using structural schematic diagrams, etc., which are merely examples and should not be construed as limiting the scope of protection of the present invention.
[0027] Please see Figures 1 to 6 A printer guide rod slider module, embodiment 1: includes an internal mounting plate 1, on which two rows of parallel V-shaped guide rods 2 are rotatably mounted. The groove surfaces of the upper and lower rows of V-shaped guide rods 2 are opposite each other and a detachable slider 3 is sandwiched between them. The two rows of V-shaped guide rods 2 are fixed or rotated synchronously. By controlling the rotation of the V-shaped guide rods 2, the slider 3 can be easily installed and removed.
[0028] Specifically, the front and rear parts of slider 3 are separable and connected by screws or magnetic blocks. The front of slider 3 has V-shaped protrusions at both ends, which engage between two rows of V-shaped guide rods 2. To enable slider 3 to move the printhead, the front of slider 3 is used to mount the printhead, while the rear is connected to a synchronous belt 4. A synchronous pulley 5 is wound around each of the left and right ends of the synchronous belt 4. One of the two synchronous pulleys 5 is connected to the drive shaft of the stepper motor 6. (See reference for details.) Figure 2 The rear part of the slider 3 is provided with a timing belt fixing groove 3a and a timing belt passing groove 3b in the vertical direction. The timing belt 4 is arranged parallel to the V-shaped guide rod 2. Based on the above technical solution, the timing wheel 5 is driven to rotate by the stepper motor 6, and the timing belt 4 moves the slider, so that the slider 3 drives the print head to move.
[0029] On the other hand, mounting blocks 1a are connected to the left and right ends of the internal mounting plate 1. The mounting blocks 1a are connected to the two ends of the V-shaped guide rods 2 through the bearing turntable 7. A synchronization mechanism 8 is provided between the two rows of V-shaped guide rods 2. The synchronization mechanism 8 includes two toothed plates that are symmetrically arranged and meshing. The two toothed plates are connected to the two rows of V-shaped guide rods 2 one by one and rotate synchronously. One end of one of the two rows of V-shaped guide rods 2 is connected to a handle 2a. The outer end of the handle 2a is fixed to the mounting block 1a by a screw 2b. By unscrewing the screw 2b and rotating the handle 2a, the V-shaped guide rod 2 can be rotated with the opening facing outward, which facilitates the installation or removal of the front part of the slider 3 and further improves the maintenance convenience of the print head. When the printer is working, the two rows of V-shaped guide rods 2 are fixed and their openings face each other.
[0030] Meanwhile, the slider 3 contacts the grooved surface of the V-shaped guide rod 2 through the rolling element. The rolling element is either a ball or a roller, which has low friction, ensuring smooth movement of the slider 3 and low printer noise.
[0031] A further optimization solution involves installing an inclined baffle plate 9 above the V-shaped guide rod 2. The left and right ends of the baffle plate 9 are inserted into slots on the inner side of the mounting block 1a to form good isolation, effectively preventing the internal wiring harness of the printer from getting tangled or interfering with the moving slider 3, thus ensuring the normal operation of the printer.
[0032] In Example 2, unlike Example 1, one end of one of the two rows of V-shaped guide rods 2 is connected to a rotary motor. By controlling the operation of the rotary motor, the automatic rotation of the V-shaped guide rods 2 is achieved, further improving the convenience of separating the slider 3 from the V-shaped guide rods 2.
[0033] In the above embodiment, the internal mounting plate 1 is formed by bending galvanized sheet metal with a thickness of 1.2mm to 1.8mm. The zinc layer on the surface of the galvanized sheet can form an electrochemical protection, which isolates the steel plate from the corrosion of air and moisture. It is especially suitable for the inside of electronic devices such as printers. When the printer is working, it may produce corrosive gases due to environmental humidity, ink evaporation and other factors. The galvanized layer can extend the service life of the mounting plate and avoid the structural strength reduction or the normal operation of internal components (such as wire harnesses and sliders) due to rust. The two ends of the internal mounting plate 1 are connected to mounting holes 1b for installation into the printer.
[0034] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. It should be noted that for those skilled in the art, any changes, modifications or additions made without departing from the concept of the present utility model should fall within the protection scope of the present utility model.
