Description

Technical Field

[0001] The present invention relates to the technical field of UV flatbed printers, and in particular to a UV flatbed printer and an X-axis driving mechanism thereof. Background Art

[0002] A UV flatbed printer is a digital printing device that uses ultraviolet curing inkjet technology. It is also called a UV inkjet printer or a flatbed UV machine. It can print images or texts directly onto the surface of various flat materials.

[0003] The UV flatbed printer mainly includes a working platform, an X-axis driving mechanism, a Y-axis driving mechanism, a beam and a printing module installed on the beam. The beam extends along the X-axis direction. The printing module can move on the beam under the action of the X-axis driving mechanism to perform scanning and printing in the X-axis direction; the beam can drive the printing module to move along the Y-axis direction under the action of the Y-axis driving mechanism to perform step-by-step printing to increase the width.

[0004] One form of the X-axis drive mechanism in the prior art is as follows Figure 1 As shown, it includes a driving motor 102, a cast aluminum frame 101, a pagoda wheel 103 and a synchronous belt 107, wherein the cast aluminum frame 101 is an integrally cast structure, which is fixedly connected to the end of the crossbeam as a whole, the driving motor 102 is embedded in and locked in the cast aluminum frame 101, and a synchronous wheel 104 is connected to the output shaft of the driving motor 102, and a synchronous belt 107 is connected between the synchronous wheel 104 and the pagoda wheel 103; the interior of the pagoda wheel 103 is provided with two bearings arranged at intervals up and down, and a transmission shaft 106 is passed through the bearings, and the upper and lower ends of the transmission shaft 106 respectively pass through the cast aluminum frame 101, and retaining springs 105 are respectively provided between the upper and lower ends of the transmission shaft 106 and the cast aluminum frame 101; a conveyor belt is wound around the small-diameter wheel body of the pagoda wheel 103, and the printing module is connected to the conveyor belt. When the pagoda wheel 103 rotates, it can drive the conveyor belt to move, thereby driving the printing module to move in the X-axis direction.

[0005] The above X-axis drive mechanism has the following disadvantages in actual use: 1. When the cast aluminum frame is cast, the size of the mounting hole for mounting the motor is fixed, which can only adapt to the installation of motors with specific power. In occasions where high power is required, the above cast aluminum frame is difficult to match and has poor versatility; 2. After the cast aluminum frame is fixed to the crossbeam, the installation height of the motor and the pagoda wheel is fixed, and the installation height of the corresponding conveyor belt used to drive the printing module to move is also fixed. It is not suitable for UV flatbed printers with different conveyor belt installation heights, and has poor versatility; 3. The upper and lower ends of the transmission shaft are clamped on the cast aluminum frame by retaining springs. During long-term operation, the transmission shaft is prone to wear. When disassembling, you need to remove the retaining springs first, and then remove the conveyor belt and pagoda wheel, which is inconvenient to disassemble. Summary of the invention

[0006] The purpose of the present invention is to provide an X-axis drive mechanism for a UV flatbed printer to solve the technical problem of poor versatility of the existing X-axis drive mechanism for UV flatbed printers; the purpose of the present invention is also to provide a UV flatbed printer to meet the printing needs of different scenarios.

[0007] In order to solve the above problems, the present invention provides an X-axis driving mechanism for a UV flatbed printer adopts the following technical solution: An X-axis driving mechanism for a UV flatbed printer comprises a mounting frame, a motor and a pagoda wheel. The pagoda wheel is rotatably assembled in the mounting frame through a transmission shaft. The mounting frame is provided with a through hole through which the output shaft of a power supply machine passes. The motor is transmission-connected to the pagoda wheel through a synchronous belt. The pagoda wheel is connected with a conveyor belt which is arranged with an interval above and below the synchronous belt and is used to drive a printing module to move along the X-axis direction. An adjusting pad is installed on the top of the motor. The adjusting pad is provided with a through hole through which the output shaft of the power supply machine passes. The adjusting pad is located below the mounting frame and is detachably connected to the mounting frame.

[0008] The beneficial effects of the present invention are as follows: the motor of the present invention is detachably connected to the mounting frame via a pad, that is, the motor can be disassembled along with the adjusting pad and the mounting frame. Since the adjusting pad is located below the mounting frame, that is, the main body of the motor is located below the mounting frame, at this time, only a through hole for the output shaft of the power supply motor to pass through needs to be provided on the mounting frame. After removing the adjusting pad and the motor, the whole can be replaced with a higher-power motor, and then fastened to the mounting frame. The present invention uses an adjusting pad to fix the motor, rather than directly locking the motor with the embedded mounting frame, so that the motor can be disassembled and replaced to meet printing needs in different scenarios.

[0009] Furthermore, the position of the adjustment pad is adjustable in a direction perpendicular to the X-axis.

[0010] Beneficial effect: When the adjusting pad is adjusted in position, the position of the motor is also adjusted accordingly, and the motor can pull the synchronous belt when moving, thereby adjusting the tightness of the synchronous belt.

[0011] Furthermore, the adjustment pad is L-shaped, including a horizontal plate body and a vertical plate body, the mounting frame is provided with an adjustment long hole extending in a direction perpendicular to the X-axis, the horizontal plate body is provided with a fixing hole corresponding to the adjustment long hole one by one, and a fixing member is movably assembled in the adjustment long hole for passing through the fixing hole to fasten the horizontal plate body to the mounting frame, the vertical plate body is provided with at least two through holes arranged at intervals along the X-axis direction, the mounting frame is provided with a threaded hole corresponding to the through holes one by one and coaxially, and an adjustment bolt threadedly matched with the threaded hole is passed through the through hole.

[0012] Beneficial effect: When changing the position of the adjustment pad, the operation is more convenient. After loosening the adjustment bolt, the adjustment pad can be moved horizontally. The fixing part can support the adjustment pad in the up and down directions, and there is no need to disassemble the adjustment pad as a whole and then adjust the horizontal position.

[0013] Furthermore, the mounting frame is provided with a plurality of leveling holes distributed around the through opening, and the leveling holes are threadedly connected with leveling bolts, and the ends of the leveling bolts are used to interfere with the horizontal plate to adjust the output shaft of the motor to a state parallel to the transmission shaft.

[0014] Beneficial effect: The leveling bolt can adjust the horizontality of the leveling pad, and can adjust the adjustment pad to a horizontal state, thereby ensuring that the output shaft of the motor is parallel to the transmission shaft, so as to achieve stable movement of the pagoda wheel and the conveyor belt.

[0015] Furthermore, the mounting frame is provided with upper and lower corresponding U-shaped notches, and a flange bearing is clamped at each U-shaped notch. The transmission shaft passes through the pagoda wheel and is assembled with two flange bearings, and both ends of the transmission shaft extend out of the mounting frame respectively.

[0016] Beneficial effects: Flange bearings can replace existing retaining springs to achieve stable assembly of the drive shaft and the mounting frame, and correspondingly achieve stable assembly of the pagoda pulley; in addition, flange bearings are easy to install and disassemble. When the drive shaft and the pagoda pulley are damaged due to long-term operation, the flange bearing can be moved out along the U-shaped notch, and the drive shaft and the pagoda pulley can be disassembled as a whole without the need to disassemble each one separately.

[0017] Furthermore, the mounting frame includes a bottom plate, a top plate, an adjustment plate and a mounting plate.

The bottom plate, the top plate and the adjustment plate form a U-shaped mounting area. The U-shaped notch is opened on the top plate and the bottom plate. The synchronous belt, the pagoda pulley and the motor output shaft are all located in the mounting area.

[0018] Beneficial effects: The mounting frame has a simple structure and can be manufactured and installed in parts; in addition, the position of the lower adjustment plate can be adjusted to be suitable for conveyor belts with different installation heights, thereby improving the versatility of the entire X-axis drive mechanism.

[0019] Furthermore, the mounting plate is provided with multiple rows of connecting holes spaced apart from each other, and the adjusting plate is provided with at least one row of fixed long holes, which extend in the up and down directions, and the distance between two adjacent connecting holes in each row is equal to the distance between two adjacent fixed long holes in each row.
