Description

Technical Field

[0001] This invention relates to the field of UV printing platform technology, and more specifically, to a UV printing platform temperature control device. Background Technology

[0002] The UV printing platform temperature control device is a closed-loop system integrated into the UV flatbed printer platform, consisting of heating or cooling components, temperature sensors, and a temperature controller. It is used to precisely control the surface temperature of the platform, suppress thermal deformation, stabilize ink viscosity, and improve adhesion and curing uniformity.

[0003] The UV printing platform temperature control device mainly consists of a heating or cooling unit, a temperature sensor, a temperature controller, and auxiliary components. Heating is achieved through PTC heating elements or heating tubes, while cooling is achieved through water-cooled copper pipes or air-cooled radiators. The platform temperature is collected in real time by thermocouple sensors. After receiving the signal, the temperature controller compares it with the set value to adjust the output power. Finally, the insulation layer, heat insulation pad, and circulating water pump provide auxiliary support.

[0004] Traditional UV printing platform temperature control devices use alternating heating plates and cooling water during UV 3D printing. This causes materials (such as photosensitive resins) to undergo rapid heating and cooling during curing, resulting in a large temperature gradient. This is not conducive to the curing of dyes in photosensitive resin materials, thus affecting the printing effect. Summary of the Invention

According to different printing needs, the drive component 5 can be driven to drive the transmission component 4 and the adjustment component 3 to operate, thereby regulating the adjustment component 3 so as to extract the liquid in different storage components 6, thereby achieving the heating or cooling effect, and the temperature change is relatively stable, avoiding large temperature gradients.

The inner sides of the first housing 31 and the second housing 32 are rotatably connected to a rotating rod 33 via a rotating shaft, and a valve 34 is fixedly connected to the outer side of the middle end of the rotating rod 33. The first gear 41 drives the two sets of rotating rods 33 and valves 34 to rotate, thereby adjusting the guiding direction of the first housing 31 and the second housing 32 by rotating the valve 34, so as to switch different liquid guidance.

[0032] like Figure 3 As shown, the transmission assembly 4 includes a first gear 41 fixedly connected to the lower end of the second housing 32, and a toothed belt 42 meshes with the outer teeth of the first gear 41.

After the second gear 43 rotates, it synchronously drives the first gear 41 at both ends to rotate through the toothed belt 42.

[0033] like Figure 5As shown, the drive assembly 5 includes a housing 51 sleeved on the outer side of the second gear 43 and the third gear 44, and both ends of the housing 51 are fixedly connected to the printer 1.

The controller 56 transmits and controls the operation of the electric telescopic rod 52. After the electric telescopic rod 52 operates, it pushes the toothed plate 53 to move under the restriction of the positioning rod 54.

[0034] like Figure 5 As shown, the electric telescopic rod 52 is fixedly connected to a transmission line 55 at the end away from the outer casing 51, and the transmission line 55 is fixedly connected to a controller 56 through the printer 1 at the end away from the electric telescopic rod 52. The controller 56 is fixedly connected to the printer 1 at the end near the printer 1. The controller 56 transmits and controls the operation of the electric telescopic rod 52. After the electric telescopic rod 52 operates, it pushes the toothed plate 53 to move under the restriction of the positioning rod 54.

[0035] like Figure 2 As shown, the storage component 6 includes a second guide pipe 61 fixedly connected to both ends of the second housing 32. A first storage box 62 and a second storage box 63 are fixedly connected to the end of the second guide pipe 61 away from the second housing 32, respectively. A drain port 64 is fixedly connected to the lower outer side of the first storage box 62 and the second storage box 63, and an injection port 65 is fixedly connected to the upper side of the first storage box 62 and the second storage box 63. A return pipe 66 is fixedly connected to the end of the first storage box 62 and the second storage box 63 away from the second guide pipe 61. The end of the return pipe 66 away from the first storage box 62 and the second storage box 63 passes through the printer 1 and is fixedly connected to the second housing 32. Different liquids are stored in the first storage box 62 and the second storage box 63 for subsequent use.

[0036] like Figure 6 As shown, the breathable component 7 includes a filter screen 71 inserted into the inner side of the upper end of the first storage tank 62, and fastening screws 72 are threaded on both ends of the filter screen 71. The lower end of the fastening screws 72 is threaded into the first storage tank 62, allowing the liquid in the first storage tank 62 to dissipate heat quickly through the filter screen 71.

[0037] like Figure 6 As shown, a mesh cover 73 is fitted on the outside of the filter screen 71, and the lower end of the mesh cover 73 is fixedly connected to the first storage box 62 by bolts, so as to protect the outside of the fan blade 83.

[0038] like Figure 6As shown, the heat dissipation assembly 8 includes a single-axis dual-head servo motor 81 fixedly connected to the middle of the filter screen 71, and a stirring paddle 82 fixedly connected to the lower output shaft of the single-axis dual-head servo motor 81 through the filter screen 71. The stirring paddle 82 is inserted into the first storage tank 62, and a fan blade 83 is fixedly connected to the upper output shaft of the single-axis dual-head servo motor 81. The liquid in the first storage tank 62 is driven by the single-axis dual-head servo motor 81, which drives the output shaft to rotate the stirring paddle 82 and the fan blade 83 simultaneously. The rotation of the stirring paddle 82 stirs the liquid in the first storage tank 62, and the rotation of the fan blade 83 causes the air above the filter screen 71 to flow rapidly, thereby dissipating the heat of the liquid in the first storage tank 62 through the filter screen 71.

[0039] like Figure 6 As shown, the heating assembly 9 includes a power supply 91 fixedly connected to the inner side of the upper end of the second storage tank 63, and a heating rod 92 fixedly connected to the lower end of the power supply 91. The power supply 91 controls the operation of the heating rod 92, and the heating rod 92 is used to heat the liquid in the second storage tank 63.

[0040] Working principle: When printing using printer 1 and substrate 11, if heating or cooling is required according to printing needs, the circulating water pump 24 can be driven to extract liquid from the first storage tank 62 or the second storage tank 63 through the first guide pipe 23 and the second guide pipe 61. When extracting liquid from the first storage tank 62, the liquid in the first storage tank 62 drives the output shaft of the single-axis dual-head servo motor 81 to rotate the stirring paddle 82 and the fan blade 83. The rotation of the stirring paddle 82 stirs the liquid in the first storage tank 62, and the rotation of the fan blade 83 causes the air above the filter screen 71 to flow rapidly, thereby dissipating the heat of the liquid in the first storage tank 62 through the filter screen 71. After being extracted, the liquid in the first storage tank 62 is diverted and injected into the heat conduction pipe 21 through the first guide pipe 23 and the distributor 22. The cooled liquid absorbs heat from the substrate 11 by flowing in the heat conduction pipe 21, thereby achieving heat dissipation. The circulating water pump 24, through the second guide pipe 23 and the second guide pipe 61, can then extract liquid from the substrate 11. When the flow pipe 61 draws liquid from the second storage tank 63, the heating rod 92 is controlled by the power supply 91 to heat the liquid in the second storage tank 63. According to the above operating principle, the heated liquid flows in the heat pipe 21, thereby heating the upper side of the substrate 11. When the liquid in the first storage tank 62 or the second storage tank 63 is exchanged as needed, the electric telescopic rod 52 is controlled by the controller 56. After the electric telescopic rod 52 is turned, it pushes the toothed plate 53 to move under the restriction of the positioning rod 54, so that the toothed plate 53 can mesh with the third gear 44, so that the third gear 44 can drive the second gear 43 to rotate. After the second gear 43 rotates, it drives the first gear 41 at both ends to rotate through the toothed belt 42, so that the first gear 41 drives the two sets of rotating rods 33 and valves 34 to rotate. The rotation of the valves 34 can adjust the guiding direction of the first housing 31 and the second housing 32 to switch different liquid guidance.

[0041] The above embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit it.
