Description

Technical Field

[0001] The utility model relates to the field of synchronous wheels, in particular to an adaptive synchronous wheel component, a printing carriage and an industrial printer. Background Art

[0002] When the inkjet printer is working, the ink is sprayed onto the printing medium on the printing platform below through the nozzle set on the printing carriage, thereby realizing the printing operation. At present, the movement of the printing carriage is generally driven by a synchronous belt drive mechanism. The synchronous belt drive is composed of a closed ring synchronous belt with equally spaced teeth on the inner surface and a synchronous pulley with corresponding teeth. During operation, the convex teeth are engaged with the tooth grooves of the synchronous pulley to transmit motion and power. It has the advantages of high transmission efficiency, no slip, and compact structure. Due to the elastic characteristics of the synchronous belt material, the synchronous belt will become loose after a period of use, causing the printing carriage to slip or collide with nearby parts during movement, which has a certain impact on the printing process. At the same time, since the synchronous belt makes a circular motion on the synchronous pulley group, it will generate resistance when reversing at the synchronous pulley group, causing the printing carriage connected to the synchronous belt to shake, affecting the printing effect.

[0003] In order to facilitate the adjustment of the synchronous belt, the utility model patent with the authorization announcement number CN216183923U discloses a printing carriage with a quick disassembly and assembly transmission belt mechanism, wherein an end plate is provided at one end of the crossbeam of the belt drive mechanism, and a U-shaped bracket is connected to the end plate. The middle part of the two support plates of the U-shaped bracket is provided with an inclined groove, and the wheel shafts at both ends of the driven pulley are inserted into the two inclined grooves. During the reciprocating motion of the belt-driven printing carriage, the driven pulley is tightened in the two inclined grooves and is not easy to loosen; at the same time, a transverse oblong hole is provided in the middle of the end plate and the folding plate on its outer side, and the side support plate and the bottom plate of the U-shaped bracket are provided with a circular hole and an oblong hole corresponding to each other, so the driven pulley can be moved along the X-axis direction and the Y-axis direction to adjust the tightness of the belt and fine-tune the position. The pulley of the driven pulley of the device is easy to disassemble and install, and the tightness of the belt can be adjusted without a complex tensioning mechanism. However, since the pulley is still fixedly installed, there is still a phenomenon of shaking when the synchronous belt turns. Utility Model Content

[0004] In order to be able to adjust the elastic band of the synchronous belt and solve the problem of shaking of the synchronous belt when it rotates and changes direction, so that it can adaptively adjust the tightness, the technical solution adopted by the utility model is: an adaptive synchronous wheel assembly, including a mounting frame, a synchronous wheel pair and an elastic connection assembly, one end of the elastic connection assembly laterally passes through the synchronous wheel pair and is connected to a side wall of the mounting frame, and the synchronous wheel pair is slidably matched with the elastic connection piece.

[0005] Based on the above, in order to facilitate installation and disassembly, the elastic connection assembly includes a driving bolt and a spring sleeved on the outside of the driving bolt, the synchronous wheel pair includes a rotating shaft and a synchronous wheel body rotatably arranged on the rotating shaft, and the threaded section of the driving bolt passes through the rotating shaft and is threadedly connected to the side wall of the mounting frame.

[0006] Based on the above, in order to realize the lateral movement of the synchronous wheel body, the spring is arranged between the rotating shaft and the side wall of the mounting frame.

[0007] Based on the above, in order to facilitate the installation of the synchronous wheel pair and the plug bolts, the mounting frame includes a vertical pad, an upper support plate and a lower support plate. The upper support plate and the lower support plate are respectively vertically arranged at the upper and lower ends of the vertical pad, and the upper support plate and the lower support plate are respectively provided with strip holes.

[0008] Based on the above, in order to limit the head of the plug bolt, an upper vertical plate is provided at the outer end of the upper support plate, and a lower vertical plate is provided at the outer end of the lower support plate. Through holes are respectively opened on the upper vertical plate and the lower vertical plate.

[0009] Based on the above, in order to reduce the weight of the mounting frame itself and facilitate observation of the movement of the rotating shaft on the synchronous wheel, the outer sides of the upper support plate and the lower support plate are respectively provided with clearance grooves.

[0010] Based on the above, in order to facilitate the assembly and installation of the plug bolts, threaded holes and assembly holes are provided on the vertical pad.

[0011] Based on the above, in order to achieve the centered installation, the upper vertical plate and the lower vertical plate are correspondingly distributed up and down, and the upper support plate is arranged in parallel with the lower support plate.

[0012] The utility model provides a printing carriage, which is equipped with the self-adaptive synchronous wheel assembly.

[0013] The utility model also provides an industrial printer, which is equipped with the printing carriage.

[0014] The utility model has substantial characteristics and progress compared with the prior art. Specifically, the adaptive synchronous wheel assembly provided by the utility model flexibly connects the upper and lower ends of the rotating shaft on the synchronous pulley to the installation frame, and realizes the lateral connection between the synchronous wheel pair and the installation frame through a pair of plug bolts and springs, so that during installation, the synchronous pulley pair can be adjusted by adjusting the tightness of the plug bolts, and the operation steps are simple. At the same time, due to the clearance fit between the rotating shaft on the synchronous wheel and the pair of plug bolts, the synchronous wheel can move freely on the plug bolts, so that it has the function of adaptively adjusting the position, and can self-adjust according to the tightness and force of the synchronous belt, so as to solve the problem of jitter of the synchronous belt when rotating and reversing, thereby improving the printing quality.

[0015] Furthermore, by providing a spring limiting groove on the rotating shaft on the synchronous wheel, one end of the spring can be limited by the spring limiting groove to prevent the spring from shifting, thereby facilitating the installation of the positioning spring.

[0016] Furthermore, by providing clearance grooves on the upper and lower support plates of the installation frame, the weight of the installation frame itself can be reduced, and the movement of the rotating shaft on the synchronous wheel can be observed more easily.

[0017] Furthermore, by symmetrically arranging the upper vertical plate and the lower vertical plate on one side of the installation frame, it is possible to ensure that the synchronous wheel is installed in a centered manner.

[0018] Therefore, the adaptive synchronous wheel assembly can adjust the elasticity of the synchronous belt, and at the same time can solve the problem of the synchronous belt shaking when the synchronous belt rotates and changes direction, so that it can adaptively adjust the tightness.
