Description

Resin recyclable photo-curing 3D printer Technical Field The application belongs to the technical field of photo-curing 3D printing, and particularly relates to a photo-curing 3D printer with recyclable resin. Background The photocuring 3D printing technology is one of the mainstream technologies with high precision and excellent surface quality in the field of additive manufacturing, and is widely applied to the fields of dentistry, medical treatment, mould, hand plate manufacturing, precision part prototype development and the like. According to the technology, the ultraviolet laser or the digital light projection equipment irradiates the liquid photosensitive resin layer by layer to enable the liquid photosensitive resin to undergo photopolymerization reaction to be cured and formed, and three-dimensional entities are formed by layer in a stacked mode, however, the traditional photocuring 3D printing technology has a remarkable material waste problem. In the printing process, a large number of support structures are usually added for supporting the cantilever structures, uncured resin remains in the trough after each printing, and performance is reduced due to pollution, moisture absorption or partial polymerization after long-term use, and finally the uncured resin is treated as waste liquid. In addition, the excess resin that adheres when the printed matter is peeled off is difficult to fully recover, resulting in a material utilization of generally less than 60%. The method not only increases the manufacturing cost, but also brings environmental burden, and particularly when the resin containing benzene or acrylic ester toxic components is used, the treatment of the waste resin is more required to meet the critical waste standard, thereby further improving the treatment cost. But common photocuring 3D prints resin recovery unit and adopts one-way scraper, is difficult to clear away the resin after the solidification, needs to strike off many times, and cleaning efficiency is low, and the liquid and the solid resin that just retrieve mix together, need the manual work again to filter just can utilize. Disclosure of Invention The application aims to solve the problems, and provides a resin recyclable photo-curing 3D printer. The application adopts the technical proposal that the photo-curing 3D printer with recoverable resin comprises, The printing mechanism comprises an equipment body, a frame body, a lifting screw rod, a fixing rod and a forming platform, wherein the frame body is fixedly connected to the upper side of the equipment body, the lifting screw rod is rotatably connected to the inner side of the frame body, the fixing rod is rotatably connected to the outer side of the lifting screw rod, and the forming platform is fixedly connected to the lower side of the fixing rod; The scraping and collecting mechanism comprises a cleaning motor, a cleaning screw rod, a sliding ring, a scraper, an extension rod and a collecting tank, wherein the cleaning screw rod is rotationally connected to the front side of the cleaning motor, the sliding ring is rotationally connected to the outer side of the cleaning screw rod, the scraper is fixedly connected to the inner side of the sliding ring, the extension rod is fixedly connected to the lower side of the sliding ring, and the collecting tank is fixedly connected to the lower side of the extension rod; the recycling filter mechanism comprises a filter screen and a filter screen handle, wherein the filter screen handle is fixedly connected to the upper part of the filter screen. Through adopting above-mentioned technical scheme, in the operation use of equipment, drive clean lead screw through clean motor and rotate, clean lead screw rotates and can drive the slip ring and remove to can clear away the liquid and the solid resin that the shaping platform is attached to the bottom when printing through the scraper, through the two-way setting of scraper, can be under clean lead screw's rotation, the attached liquid and the solid resin of shaping platform bottom is scraped back and forth, improves cleaning efficiency and effect. Through the setting of fixed die-pin, can be in strike off the attached liquid and solid resin collecting vat of shaping platform bottom and hold in the palm to through collecting the inside liquid and solid resin of collecting vat, when the slip ring drove the collecting vat and reached fixed die-pin end, through the setting of extension rod and rotation connecting block, can make the collecting vat become vertical state under the action of gravity, thereby pour the liquid and the solid resin of collecting into the filter screen, liquid resin flows into the resin inslot through the filter screen lateral wall, through the setting of the device, can filter recycle with liquid resin, solid resin stays in the filter screen and collects.
