Description

Technical Field

[0001] This utility model relates to the field of 3D printer technology, specifically to a 3D printer feed trough assembly. Background Technology

[0002] With the development of technology, 3D printing is being used more and more. Typically, 3D printers print an object layer by layer, especially those using SLA (Stereolithography) technology. SLA is based on the principle that photosensitive resin solidifies when exposed to ultraviolet light. A computer, using a CAD drawing of the layered cross-section of the object to be printed, controls the light source to illuminate selected areas of liquid photosensitive resin, thus solidifying and printing that portion of the photosensitive resin. After layer-by-layer solidification and printing, a solid object is finally obtained.

[0003] Utility model patent CN213500882U discloses a material slot locking structure for a 3D printer and a 3D printer. This utility model includes a machine base, a material slot, and a locking mechanism disposed on the machine base. The machine base has a light-transmitting hole and several positioning slots arranged around the light-transmitting hole. Several supporting members protruding from the bottom surface of the material slot are provided. The locking mechanism includes several locking buckles, which are rotatably disposed on the machine base and arranged around the light-transmitting hole. When the material slot is placed on the machine base, the supporting members engage with the positioning slots, and the locking buckles, when rotated, lock the material slot onto the machine base. This utility model's material slot locking structure, through the supporting members at the bottom of the material slot, not only stably positions the material slot, preventing it from sliding or shifting, but also supports the material slot, suspending the release film on the bottom surface of the material slot and preventing damage to the release film.

[0004] While the aforementioned utility model can stably position the material tray, it is not easy to clean the inside of the tray when the type of filler needs to be changed after use. Residual filler from the previous type can affect subsequent printing. Therefore, we propose a material tray assembly for a 3D printer. Utility Model Content

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figures 1-4 This embodiment provides a technical solution:

[0027] A 3D printer feed trough assembly includes a feed trough 1. Slide rods 2 are welded to both the left and right sides inside the feed trough 1. A scraping mechanism 3 is slidably connected between the two slide rods 2. The scraping mechanism 3 includes a moving mechanism 31 and a scraper mechanism 32 connected to the front side of the moving mechanism 31.

[0028] Specifically, the moving mechanism 31 includes a sliding rod 314, two sliding grooves 311 formed at the left and right ends of the bottom surface of the sliding rod 314, and a mounting plate 315 welded to the bottom surface of the sliding rod 314. The sliding grooves 311 are slidably connected to the surface of the sliding rod 2. An auxiliary groove 313 is formed in the middle of the bottom surface of the mounting plate 315, and through grooves 312 are formed on the top of both the left and right sides of the mounting plate 315. The scraper mechanism 32 includes a scraper 321, two side baffles 322 welded to the left and right sides of the top surface of the scraper 321, a support frame 323 welded to the rear side of each side baffle 322, and an auxiliary frame 325 welded to the middle of the rear side of the scraper 321. The auxiliary frame 325 is used to insert into the auxiliary groove 313, and the bottom of the support frame 323 is fixedly connected to the top surface of the scraper 321. With the above mechanism, the material inside the trough 1 can be easily cleaned without removing the trough 1.

[0029] Furthermore, both support frames 323 have limit grooves on their top surfaces, and limit rods 324 are engaged between the inside of the two limit grooves. An auxiliary rod is welded between the inner sides of the auxiliary frame 325, and elastic Velcro 326 is fixedly installed on the auxiliary rod. The scraper 321 is fixed to the front side of the mounting plate 315 by the cooperation of the elastic Velcro 326 and the limit rod 324.

[0030] In this embodiment, both the front and rear sides of the sliding groove 311 are rounded to facilitate the tilting of the sliding rod 314.

[0031] In this embodiment, the bottom of the mounting plate 315 is made of silicone material, and the scraper 321 is also made of silicone material to prevent damage to the inside of the material tank 1 during the scraping process.

[0032] In this embodiment, the tops of the two support frames 323 can be respectively engaged in the through slots 312 on the left and right sides of the mounting plate 315, so that the support frames 323 are engaged on the mounting plate 315.

[0033] In this embodiment, the bottom surface of the scraper 321 can be closely attached to the bottom wall inside the trough 1, and the side baffle 322 has a right-angled triangular structure in its front view. The scraper 321, together with the side baffle 322 and the mounting plate 315, can empty the scraped material from the trough 1 after tilting.

[0034] In this embodiment, the front side of the limiting rod 324 is closely attached to the rear side of the mounting plate 315, and a gap is provided in the middle of the limiting rod 324 for the elastic hook and loop fastener 326 to pass through. In use, the end of the elastic hook and loop fastener 326 is passed through the gap on the limiting rod 324 and then wrapped back. The end of the elastic hook and loop fastener 326 is then adhered to the elastic hook and loop fastener 326, which facilitates the limiting rod 324 to be limited and fixed by the elastic hook and loop fastener 326.

[0035] In the specific use of the 3D printer material tank assembly of this embodiment, when it is necessary to replace the material in the material tank 1, the sliding groove 311 on the sliding rod 314 is installed on the sliding rod 2. Then, the scraping mechanism 3 can be tilted backward. Since the material tank of the 3D printer is usually filled with resin, which is both fluid and viscous, the scraping mechanism 3 can be tilted to clean the bottom wall of the material tank 1. Then, the scraper 321 is set close to the bottom wall of the material tank 1, and the scraper 321 can easily scrape the material in the material tank 1. Then, the moving mechanism 31 is pushed to move on the sliding rod 2 so that the scraper 321 can scrape off most of the material. After scraping off a sufficient amount of coating, the scraper 321 is pushed to the rear side. Then, the scraping mechanism 3 is controlled to tilt forward so that the scraper 321, together with the side baffle 322 and the mounting plate 315, can scoop out part of the scraped material. By repeating the operation multiple times, the material inside the material tank 1 can be cleaned.

[0036] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model.
