Description

[0002] Current photocuring printers generally use UV curing technology for photosensitive resins. During the photosensitive resin molding process, low temperatures have a negative impact on the rapid reflow of the photosensitive resin during printing, and also have a certain negative impact on the molding effect. Therefore, a heating device is needed to increase the printing environment temperature.

[0003] Currently, some heating devices use a single axial fan and are integrated with the light-curing printer. The heating device is placed inside the printer housing and powered by the printer power supply.

[0047] Figure 6 The fan of the environmental heating device for the light-curing printer according to the embodiment of the present application is shown side by side.

Figure 5 A thermal detection module 8 is added to the control module 3; in the figure, the thermal detection module 8 is disposed at the air inlet of the second centrifugal fan 22; the thermal detection module 8 is electrically connected to the control module 3; the thermal detection module 8 is used to detect the inlet air temperature, thereby facilitating the control module 3 to adjust the speed of the first centrifugal fan 21 and the second centrifugal fan 22, and facilitating the control module 3 to adjust the heating power of the heating module 1.

[0049] Figure 8 This is a schematic diagram of the adhesive unit of the environmental heating device for the light-curing printer according to the embodiment of the present application. As shown in the figure, an adhesive unit 9 is added to the figure; Figure 3 As shown, a mounting slot 91 is provided on the outer side of the middle frame 53; thus, the adhesive unit 9 can be detachably fixed to the mounting slot 91.

[0050] Figure 9 This is a schematic diagram of a use scenario of the environment heating device for a light-curing printer according to an embodiment of the present application. As shown in the figure, the light-curing printer 200 has a resin tank 201, a lifting guide rail 202, and a housing 203. When the ambient temperature is low and not conducive to resin curing printing, it is necessary to increase the resin temperature in the resin tank 201. In this case, the environment heating device 100 according to the embodiment of the present application can be used to heat the closed environment in the housing 203. The environment heating device 100 can be used to heat the closed environment in the housing 203.

[0051] In particular, as shown in the figure of the light-curing printer 200, it can be seen that in general light-curing printers, the free space between the box cover 203, the resin tank 201 and the lifting guide rail 202 is limited. Therefore, only when the volume of the environmental heating device 100 is smaller and the relative heating efficiency is greater can it be better adapted and installed on models of different sizes. Therefore, the side-by-side arrangement of the dual centrifugal fans of the environmental heating device 100 in the embodiment of the present application can greatly improve the heating efficiency of the heating device per unit volume, thereby achieving better adaptability and compatibility.
