Description

Technical Field

[0001] This utility model relates to the field of printing equipment, and in particular to a UV printing suction platform drive device. Background Technology

[0002] In a UV printer, the print platform serves as the physical support and working reference for the entire printing process. Its core function is to accurately and stably support and fix the substrate to be printed (such as acrylic, metal, glass, wood, plastic, leather, etc.). The print platform possesses extremely high flatness and rigidity to ensure that the printhead maintains a precise distance (Z-axis height) when moving to eject UV ink, which is crucial for obtaining clear and sharp images.

[0003] Printing platforms typically have height adjustment functions to adapt to the printing needs of materials of different thicknesses. The invention patent with application number CN2023213779386 discloses a lifting platform for UV printing of deep grooved plates. This lifting platform has a lead screw set in the middle, and the height of the printing platform is adjusted by rotating the lead screw through a motor. This lifting structure has the problems of limited height adjustment range and poor lifting adjustment stability, which need to be improved. Utility Model Content

[0005] The technical solution of this utility model is: a UV printing suction platform driving device, including a Y-axis moving component and a lifting platform component installed on the Y-axis moving component, which drives the lifting platform component to move; the Y-axis moving component includes a supporting base plate, a negative pressure platform and a driver, and flange bearings are provided at the four corners of the supporting base plate. Driven pulleys are fixedly mounted on the flange bearings. The flange bearings and driven pulleys rotate as a unit. The driver is located at the middle of the end of the supporting base plate. The output end of the driver is connected to a driving pulley. The side of the driving pulley is evenly distributed with ribs. The side of the driven pulley is also evenly distributed with ribs. A synchronous belt connects the driving pulley and the four driven pulleys.

[0006] The flange bearing is internally threaded with lifting screws, which are vertically connected inside the flange bearing. The negative pressure platform is horizontally fixed between the upper ends of the four lifting screws.

[0007] Preferably, two guide wheels are arranged side by side on the support base plate inside the driver, and a certain distance is provided between the guide wheels and the driven pulleys. The synchronous belt passes around the two guide wheels and is then fitted onto the driven pulleys on both sides.

[0008] Preferably, the negative pressure platform has a hollow cavity inside, and the surface of the negative pressure platform is densely covered with small holes communicating with the hollow cavity, with a conical section at the upper part of the small holes.

[0009] Preferably, the negative pressure platform has a platform adjustment plate with an integral concave shape on both sides of its bottom surface. The upper end of the lifting screw is fixedly connected to the platform adjustment plate. A fixing rod is provided between the concave parts at both ends of the platform adjustment plate, and the two fixing rods are arranged parallel to each other.

[0010] Preferably, the Y-axis moving component includes two guide columns and a sliding seat fixed side by side in the base frame.

[0016] Example 1: A UV printing suction platform drive device includes a Y-axis moving component 02 and a lifting platform component 01 mounted on the Y-axis moving component 02. The Y-axis moving component 02 includes a support base plate 11, a negative pressure platform 19, and a driver 16. The driver 16 is a geared motor. Flange bearings 12 are provided at the four corners of the support base plate 11. Driven pulleys 13 are fixedly mounted on the flange bearings 12. The driven pulleys 13 and the flange bearings 12 are an integral structure. The driver 16 is located at the middle of the end of the support base plate 11. The output end of the driver 16 is connected to a drive pulley 14. A synchronous belt 15 is connected between the drive pulley 14 and the four driven pulleys 13. The synchronous belt 15 is square and mounted between the four driven pulleys 13. The flange bearing 12 is internally threaded with lifting screws 17. The negative pressure platform 19 is horizontally fixed between the upper ends of the four lifting screws 17. The four lifting screws 17 are at the same height, supporting the negative pressure platform 19 in a horizontal state.

[0017] The negative pressure platform 19 has a hollow cavity 191 inside, a round hole in the middle of the bottom plate of the negative pressure platform 19, a fan at the round hole, and small holes 192 communicating with the hollow cavity 191 are densely distributed on the surface of the negative pressure platform 19.

[0018] The negative pressure platform 19 has concave platform adjustment plates 201 on both sides of its bottom surface. A fixing rod 202 is provided between the recesses at both ends of the platform adjustment plate 201. The concave platform adjustment plate 201 is used to accommodate the fixing rod 202. The fixing rod 202 and the platform adjustment plate 201 form a square frame support structure, which is supported on the bottom surface of the negative pressure platform 19.

[0019] The principle of the UV printing suction platform drive device in this embodiment is as follows: the Y-axis moving component 02 drives the lifting platform component 01 to move in the Y direction inside the printer, cooperating with the X-axis moving printing carriage to perform printing operations. The lifting platform component 01 drives four flange bearings 12 to rotate synchronously on the support base plate 11 through a driver 16. The synchronous rotation of the four flange bearings 12 drives four lifting screws 17 to adjust the height of the pressure platform. The four-corner support structure of the four lifting screws 17 can ensure that the negative pressure platform 19 can remain in a stable horizontal state even with frequent lifting and lowering, ensuring print quality. At the same time, the belt-driven driven wheel drives the lifting screws 17, which will not obstruct the lower end of the lifting screws 17, increasing the lifting stroke of the lifting screws 17, thereby improving the height adjustment range of the negative pressure platform 19, making it able to adapt to the printing of products of more specifications and sizes.

[0020] Example 2, see appendix Figure 3 This embodiment is basically the same as Embodiment 1, and the similarities will not be repeated. The difference is that two guide wheels 18 are arranged side by side on the support base plate 11 inside the driver 16. The synchronous belt 15 passes around the two guide wheels 18 and then fits onto the driven pulleys 13 on both sides. The guide wheels 18 change the direction of the synchronous belt 15, increasing the area of ​​the synchronous belt 15 wrapped around the two driven pulleys 13 at the ends, thereby increasing the friction between them and preventing relative slippage. At the same time, by adjusting the position of the guide wheels 18, the tension of the synchronous belt 15 can also be adjusted to ensure the driving effect.

[0021] Example 3, see appendix Figure 4-6 This embodiment is basically the same as Embodiment 1, and the similarities will not be repeated. The difference is that the Y-axis moving component 02 includes two guide columns 21 and a sliding seat 22 fixed side by side in the base frame. The sliding seat 22 is provided with sliding sleeves 23 on both sides. The two sliding sleeves 23 are respectively slidably fitted onto the two guide columns 21. The sliding seat 22 slides along the guide columns 21 through the two sliding sleeves 23. L-shaped support legs 24 are provided on both sides of the bottom surface of the support base plate 11. The lower end of the L-shaped support leg 24 is fixedly connected to the upper surface of the sliding seat 22, thus fixing the lifting platform component 01 and the sliding seat 22 into one unit. A protective shell 203 is provided on the base frame. Two long holes are provided side by side on the protective shell 203. The L-shaped support leg 24 extends into the base frame from the long holes and connects with the sliding seat 22. A drive component is provided in the base frame.

[0022] The drive assembly includes a traction wheel and a support wheel 25 mounted on a base frame between the two guide columns 21. A traction belt 26 is fitted between the traction wheel and the support wheel 25. A clamping plate 27 is provided in the middle of the bottom surface of the sliding support. The clamping plate 27 consists of a fixed plate and a clamping plate. The traction belt 26 is fixedly connected to the bottom surface of the sliding support through the clamping plate 27. The front wheel is driven by a motor. The Y-axis movement assembly 02 drives the traction wheel to rotate via a motor. The traction wheel drives the traction belt 26 to rotate between the traction wheel and the support wheel 25. The traction belt 26 pulls the sliding seat 22 to slide along the two guide columns 21, realizing the Y-axis movement of the lifting platform assembly 01.
