[0042] Preferably, the machining platform 1 comprises more than one mXf plate spliced.

[0043] The following is a detailed description of the specific embodiment of the desktop engraving machine using the belt roller structure, which aims to help understand the technical content and practical effect of the present application.

[0044] The desktop engraving machine of the present embodiment mainly comprises a processing platform 1, an X-axis moving module 2, a Y-axis moving module 3, a Z-axis moving module 9, a processing spindle 10, and a control system (not shown in the figure).

[0045] The processing platform 1 is used to install the workpiece to be processed, which can be spliced by one or more mXf plates to meet the processing needs of workpieces of different sizes. The mXf material will not collide with the tool during cutting, which can prevent accidents. Compared with the processing platform 1 made of pure aluminum plate, the mXf plate is safer and more lightweight, which reduces the weight of the whole machine.

[0046] In the present embodiment, the X-axis moving module 2 and the Y-axis moving module 3 adopt the same structure. The Y-axis moving module 3 drives the Z-axis moving module 9 and the processing spindle 10 to move in the Y-axis direction. The two ends of the Y-axis moving module 3 are installed on the X-axis moving module 2, and the X-axis moving module 2 drives the Y-axis moving module 3 to move in the X-axis direction. The following will be described with respect to the Y-axis moving module 3.

[0047] The Y-axis moving module 3 comprises a Y-axis profile 4, a Y-axis moving assembly 5, a Y-axis motor 6, a Y-axis synchronous wheel 7, and a Y-axis transmission belt 8. The tooth surface on the Y-axis transmission belt 8 is engaged with the tooth surface of the Y-axis synchronous wheel 7 for transmission. The first end of the Y-axis transmission belt 8 is fixed to one end of the Y-axis profile 4 by passing through the Y-axis moving assembly 5, and the second end is also fixed to the other end of the Y-axis profile 4 by passing through the Y-axis moving assembly 5.

[0048] In the implementation, the Y-axis moving assembly 5 comprises a Y-axis first base plate 11, a Y-axis second base plate 12, and a Y-axis rolling wheel set 13. Y-axis slides 14 are respectively arranged on the upper and lower end surfaces of the Y-axis profile 4. Preferably, the Y-axis rolling wheel set 13 adopts a four-rolling wheel form. Two rolling wheels are arranged on the upper end surface of the Y-axis profile 4, and two rolling wheels are arranged on the lower end surface of the Y-axis profile 4. The rolling wheels are installed on the Y-axis first base plate 11 and the Y-axis second base plate 12. Under the limiting of the Y-axis first base plate 11 and the Y-axis second base plate 12, the Y-axis moving assembly 5 is closely combined with the Y-axis profile 4. The Y-axis transmission belt 8 passes through the rolling wheels in sequence on the Y-axis synchronous wheel 7, and is in contact with the Y-axis slides 14 under the pressing of the rolling wheels.

[0049] The movement process is as follows: the Y-axis motor 6 drives the Y-axis synchronous wheel 7 to rotate. Since the Y-axis synchronous wheel 7 is engaged with the Y-axis transmission belt 8, and the Y-axis moving module 3 is limited on the Y-axis profile 4, the Z-axis moving module 9 and the processing spindle 10 installed on the Y-axis moving module 3 move in the Y direction.

[0050] Due to the structure, the noise level of the desktop engraving machine in the working process is significantly reduced, and the moving speed and processing efficiency are improved; the rolling wheel set on the moving assembly presses the belt on the slide, and the belt is hidden inside the profile, providing a certain safety for the belt.

[0051] The principle of the X-axis moving module 2 can refer to the principle of the Y-axis moving module 3 described above, and will not be described again.

[0052] The Z-axis moving module 9 is installed on the X-axis moving assembly 23 and is used to realize the movement of the machining spindle 10 in the Z-axis direction. The Z-axis moving module 9 includes a Z-axis frame 38, a Z-axis motor 39, a trapezoidal screw 40, an optical axis 41, a Z-axis moving block 42, a spindle clamp 43, and a fixed strip 44. The trapezoidal screw 40 is connected with the output end of the Z-axis motor 39, and the optical axis 41 is arranged in parallel with the trapezoidal screw 40. The Z-axis moving block 42 is sleeved on the trapezoidal screw 40 and the optical axis 41, the spindle clamp 43 is arranged on the Z-axis moving block 42 and is used to clamp the machining spindle 10. The fixed strip 44 is provided with a limit switch for limiting the movement range of the Z-axis moving block 42.

[0053] The control system is used to receive signals and output signals, control the operation of the X-axis motor 24, the Y-axis motor 6 and the Z-axis motor 39, so as to realize the three-dimensional movement and processing operation of the desktop engraving machine. The control system can realize various complex engraving patterns and processing paths through programming.

[0054] Further, in order to realize the adjustment of the tension of the transmission belt, the X-axis tension adjusting device 31 and the Y-axis tension adjusting device 15 are arranged on the X-axis moving module 2 and the Y-axis moving module 3.

[0055] The X-axis tension adjusting device 31 and the Y-axis tension adjusting device 15 are newly designed compact tension adjusting structures. Since the X-axis tension adjusting device 31 and the Y-axis tension adjusting device 15 adopt the same structure and principle, the following will be described with the Y-axis tension adjusting device 15.

[0056] The Y-axis tension adjusting device 15 includes a Y-axis housing 16, a Y-axis roller 17, a Y-axis sliding block 18, a Y-axis fixed block 19, and a Y-axis adjusting screw 20. The Y-axis housing 16 has a longitudinal Y-axis sliding groove 21, the Y-axis roller 17 is installed on the upper part of the Y-axis sliding groove 21, and the Y-axis adjusting screw 20 is arranged below the Y-axis roller 17. The Y-axis sliding block 18 is sleeved on the Y-axis adjusting screw 20 and is arranged at the position of the Y-axis sliding groove 21, and the Y-axis fixed block 19 is used to fix the Y-axis transmission belt 8 on the Y-axis sliding block 18.

[0057] The Y-axis transmission belt 8 passes through the Y-axis slider 18 through the Y-axis roller 17, and is fastened by the Y-axis fixed block 19 through a screw, and the Y-axis adjusting screw 20 is twisted to slide the Y-axis slider 18 upwards to realize the loosening of the Y-axis transmission belt 8, and vice versa.

[0058] The X-axis tension adjusting device 31 of the X-axis transmission belt 26 is similar in structure and will not be described herein.

[0059] The above is not any limitation on the technical range of the utility model, and any modification, equivalent change and modification of the above embodiments according to the technical essence of the utility model still belong to the range of the technical scheme of the utility model.
