Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of 3D printing, in particular to a drip-proof curved nozzle flow guide resin tank and a 3D printer using the same. BACKGROUND

[0002] At present, 3D printing resin tanks are commonly used in light-cured 3D printing forming technology to hold resin solution. When pouring the resin solution for recycling, the resin solution often hangs on the wall and drips along the edge of the resin tank. Since the resin solution is not easy to clean and is a liquid with certain hazards, the dripping not only pollutes the environment but also causes continuous harm. Some existing resin tanks have a shallow groove on the inner edge of the corner opening for flow guide, or a protruding flat mouth flow guide groove is further arranged at the position of the shallow groove for flow guide. However, these designs do not consider the situation that the resin solution flows downward and drips along the edge of the flat mouth flow guide groove when the resin tank is placed flat, or the resin solution directly flows downward and drips along the outer wall of the resin tank. Therefore, manual wiping is usually required, and pollution caused by dripping of the resin solution is likely to occur during use. Therefore, a resin tank for preventing dripping of the resin solution is needed. CONTENT OF THE UTILITY MODEL

[0003] The purpose of the present application is to provide a drip-proof curved nozzle flow guide resin tank and a 3D printer using the same. The drip-proof curved nozzle flow guide resin tank adopts a front-narrow rear-wide downward curved groove type flow guide curved nozzle for flow guide when pouring the resin solution, so that the resin solution can be fully dripped to avoid dripping pollution caused by adhesion of the resin solution to the bottom hanging surface of the flow guide curved nozzle. The flow guide curved nozzle is also used for hooking the mouth of a resin solution recycling container to achieve labor-saving pouring, so that the pouring action is more stable and the resin flow rate during pouring can be more easily and stably controlled.

[0004] The drip-proof curved nozzle flow guide resin tank provided by the present application comprises a frame, a release film, a film fixing frame and a flow guide curved nozzle. The frame is a hollow tank body. A flow guide notch is arranged on the frame. The flow guide curved nozzle is a front-narrow rear-wide downward curved groove. The flow guide curved nozzle is connected to the flow guide notch. The nozzle end of the front part of the flow guide curved nozzle is lower than the lowest point of the flow guide notch. The release film is used for light-cured printing light transmission and release film peeling. The film fixing frame tightens and fixes the release film to the bottom of the frame, so that the release film and the frame form a resin tank. The resin tank is used to hold resin solution. The flow guide curved nozzle is used for flow guide when pouring the resin solution. The downward curved groove of the flow guide curved nozzle enables the resin solution to be fully dripped. When the resin tank is placed flat, the resin solution is prevented from adhering to the bottom hanging surface of the flow guide curved nozzle to cause dripping pollution. The flow guide curved nozzle is also used for hooking the mouth of a resin solution recycling container to achieve labor-saving pouring.

[0005] Preferably, the inner surface of the guide nozzle groove is coated with a liquid anti-adhesion coating.

[0006] Preferably, the inner surface of the guide nozzle groove is smooth.

[0007] Preferably, the guide nozzle is shaped as a downward curved arc-shaped groove or a downward curved angle-shaped groove.

[0008] Preferably, the number of guide notches and guide nozzles is one or more, respectively.

[0009] Preferably, the frame is shaped as a circle or a square.

[0010] Preferably, the film fixing frame is a clamping film frame, which is used to clamp the release film and make the release film taut and fixed towards the bottom of the frame.

[0011] Preferably, the film fixing frame is a pressing film frame, which directly makes the release film taut and fixed towards the bottom of the frame.

[0012] The purpose of the present application is also to provide a 3D printer, in particular the 3D printer, comprising the drip-proof nozzle guide resin tank.

[0013] Compared with the prior art, the present application has the following beneficial effects:

[0014] 1. The drip-proof nozzle guide resin tank of the present application can make the resin solution fully drip to avoid dripping pollution caused by the adhesion of the resin solution to the bottom hanging surface of the guide nozzle, while facilitating pouring and guiding, compared with the resin tank with a prominent flat mouth guide groove.

[0015] 2. The drip-proof nozzle guide resin tank of the present application can also be used to hook the mouth of a recycling container to achieve labor-saving pouring, thereby making the pouring action more stable and the resin flow rate during pouring more easily controlled, compared with the resin tank with a prominent flat mouth guide groove.
