Abstract
Description
Technical Field
[0001] This application relates to the field of 3D printing technology, specifically to an anti-drip guiding resin tank for 3D printing and a 3D printer using the anti-drip guiding resin tank. Background Technology
[0002] Currently, photopolymer 3D printing technology commonly uses 3D printing resin tanks to hold resin solutions. When emptying the resin solution for recycling, it often drips and clings to the tank walls. Since resin solutions are difficult to clean and are potentially hazardous liquids, these drips not only pollute the environment but also cause ongoing damage. Existing direct-extension single-layer nozzles offer some anti-drip effect for fast-moving fluids; however, when applied to viscous fluids like resin solutions, the flow is difficult to interrupt quickly, leading to liquid residue at the nozzle tip. This results in dripping even when the resin tank is level. Therefore, these extension single-layer nozzles cannot effectively prevent dripping and usually require manual wiping. Thus, a device is needed to prevent resin solution dripping. Utility Model Content

A reflux zone is provided on the frame. The reflux zone has a collection surface. The guide plate is connected to the collection surface. The guide plate is used to guide the resin solution when it is poured. The collection surface collects the resin solution adhering to the back wall and flowing down from the guide plate, and the collection surface allows the collected resin solution to flow back into the resin tank, bypassing both sides of the guide plate, thereby preventing the resin solution from dripping when the resin tank is level.

In the figure, the frame 1 is a hollow tank; the frame 1, the release membrane 2, and the solid membrane frame 3 together constitute the resin tank, which is used to hold the resin solution; specifically, the solid membrane frame 3 in the figure is a pressure frame; the solid membrane frame 3 directly tightens and fixes the release membrane 2 to the bottom of the frame 1, and the edge of the release membrane 2 is provided with positioning holes 21. Fasteners 31 penetrate the solid membrane frame 3 and the positioning holes 21 and are fixed to the bottom of the frame 1.
[0027] In addition, a sunken reflux zone 4 is provided at one corner of the upper part of the frame 1; a collection surface 41 is provided in the reflux zone 4; specifically, the collection surface 41 in the figure is a horizontal plane; and a boss 42 is provided on the outer edge of the collection surface 41; the boss 42 is used to contain the resin solution on the collection surface 41 inward.
[0028] In addition, a settling tank 43 is provided on the collection surface 41 of the return zone 4; a sealing gasket 44 is provided in the settling tank 43; the lower end of the guide plate 5 is inserted into the sealing gasket 44; the sealing gasket 44 is used to maintain the seal between the guide plate 5 and the collection surface 41 to prevent resin solution from accumulating in the gaps; the guide plate 5 is used to guide the flow when pouring resin solution; the collection surface 41 is used to collect the resin solution hanging on the back wall and flowing down of the guide plate 5, and the collection surface 41 allows the collected resin solution to bypass both sides of the guide plate 5 and flow back into the resin tank, thereby preventing the resin solution from dripping when the resin tank is level.
[0029] Furthermore, a flow guide 10 is provided on the inner edge of the frame 1; the flow guide 10 is connected to the flow collection surface 41; the flow guide 10 is used to guide the flow in conjunction with the flow guide plate 5 when pouring resin.
[0030] Finally, it can be seen in the figure that there are two mounting holes 12 on the upper part of the frame 1 on both sides of the recirculation zone 4; the two ends of the guide plate 5 can be fixed to the mounting holes 12 by means of the fasteners 6.
[0031] Figure 3 This is an exploded view of the anti-drip guiding resin tank used for 3D printing, as described in an embodiment of this application. Figure 2 As shown in the figure, this figure is... Figure 2 Based on the above, the reflux zone 4 is enlarged and shown. Specifically, a sunken reflux zone 4 is set at one corner of the upper part of the frame 1; a horizontal plane collecting surface 41 is set in the reflux zone 4, which is the shaded part in the figure; and a wall-like protrusion 42 is set on the outer edge of the collecting surface 41. The protrusion 42 is used to contain the resin solution on the collecting surface 41 inward.
[0032] In particular, in this Figure 3 and Figure 2 The reflux zone 4 shown uses a sink 43, a sealing gasket 44, and a guide plate 5; end ears 52 are designed at both ends of the guide plate 5 for fixing; it should be stated that this specific design is not intended to limit the solution of this application; if the guide plate 5 is designed to be bonded to the bottom of the collecting surface 41, then the sink 43, the sealing gasket 44 and the end ears 52 can be omitted.
[0033] Accordingly, when designing the product of this application, two right angles on the same side or two right angles on opposite sides of the frame 1 can be selected to set the return flow area 4 and the guide plate 5; consequently, it may be more convenient to use.

[0035] Specifically, a notch 55 is provided between the guide surface 51 and the end ear 52. In actual design and use, the vertical projection area of the guide surface 51 needs to be smaller than the area of the collecting surface 41. The purpose is to guide the liquid into the collecting surface 41 when the notch 55 is used for liquid pouring and the flow rate is too large, so as to prevent the liquid from overflowing outward from both sides of the guide surface 51. At this time, the collecting surface 41 can receive the liquid overflowing from the notch 17.
