[0001] This utility model relates to the field of 3D printing technology, specifically to a molding and peeling device for a photopolymer 3D printer. Background Technology

[0002] Photopolymer 3D printers are computer-aided devices that use photopolymerization technology to create objects. They construct three-dimensional models by curing liquid photosensitive resin in layers, resulting in higher printing accuracy and surface smoothness, achieving a texture-free effect and producing more robust finished products.

[0003] However, most existing photopolymer 3D printers require manual peeling of the finished product using a hand-held spatula after printing, which is inconvenient for users.

[0004] To address the aforementioned problems, this application proposes a photopolymer 3D printer molding and peeling device to solve these problems. Utility Model Content

[0005] To address the problem that most existing photopolymer 3D printers require manual peeling of the finished product using a hand-held spatula after printing, the purpose of this invention is to provide a peeling device for photopolymer 3D printers.

[0006] To solve the above-mentioned technical problems, this utility model adopts the following technical solution: a photopolymerization 3D printer molding peeling device, including a base, a peeling mechanism for use on the base, and a limiting mechanism for use on the peeling mechanism. The peeling mechanism includes an electric cylinder body, which is fixedly installed at the bottom end of the base. An electric cylinder slider is slidably mounted on the electric cylinder body, and a slide frame is fixedly sleeved on the electric cylinder slider. The slide frame is slidably connected to the base. A symmetrically arranged U-shaped rod is fixedly installed at the bottom end of the base, and the slide frame is slidably sleeved on the U-shaped rod. The upper part has symmetrically distributed sliding holes, and the U-shaped rod slides through the sliding holes. Both ends of the slide are rotatably inserted with lead screws, and the opposite ends of the lead screws are fixedly connected with rotating wheels. Rotating rods are rotatably inserted on the rotating wheels. The lead screws are threaded with brackets, and the brackets are slidably connected to the slide. Both ends of the slide are fixedly inserted with symmetrically arranged guide rods, and the brackets are slidably sleeved on the guide rods. The lower end of the bracket has symmetrically distributed guide holes, and the guide rods slide through the guide holes. The tops of the two brackets are detachably equipped with scrapers, and the scrapers can slide and fit against the top of the base.

[0007] Preferably, the limiting mechanism includes a rotating ring, an inner groove is provided inside the upper end of the bracket, and the rotating ring is rotatably inserted into the inner groove. A torsion spring is fixedly installed at the bottom end of the rotating ring, and the end of the torsion spring is fixedly connected to the inner wall of the inner groove. A rotating shaft is fixedly inserted into the middle of the rotating ring, and a convex block is fixedly sleeved at the top end of the rotating shaft. Both ends of the shovel are provided with convex grooves, and the convex block can slide through the convex grooves. A handwheel is rotatably inserted into one end of the convex block, and the outer wall of the handwheel is covered with an anti-slip texture.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0019] Example: Figures 1-5 As shown, this utility model provides a molding peeling device for a photopolymer 3D printer, including a base 1. The base 1 is a support structure at the bottom of the photopolymer 3D printer for supporting the printing material. Components fixedly installed on the base 1 can be fixedly installed by bolts, which is prior art and will not be described in detail here. The base 1 is provided with a peeling mechanism 2 for cooperation, and the peeling mechanism 2 is provided with a limiting mechanism 3 for cooperation. The peeling mechanism 2 includes an electric cylinder body 21, which is fixedly installed at the bottom of the base 1. An electric cylinder slider 22 is slidably mounted on the electric cylinder body 21. The electric cylinder body 21 and the electric cylinder slider 22 are controlled to open and close by a PLC control module, which is prior art and will not be described in detail here. A slide frame 23 is fixedly sleeved on the electric cylinder slider 22, and the slide frame 23 is slidably connected to the base 1. A symmetrically arranged U-shaped rod 211 is fixedly installed at the bottom of the base 1, and the slide frame 23 is slidably sleeved on the U-shaped rod 211. The slide 23 has symmetrically distributed sliding holes 212, and a U-shaped rod 211 slides through the sliding holes 212. The cooperation between the U-shaped rod 211 and the sliding holes 212 limits and guides the movement adjustment of the slide 23. Both ends of the slide 23 are rotatably connected to lead screws 24, and the opposite ends of the lead screws 24 are fixedly connected to rotating wheels 25. Rotating rods 26 are rotatably connected to the rotating wheels 25. A bracket 27 is threaded onto the lead screw 24, and the bracket 27 slides with the slide 23. The slide 23 is connected to a sliding frame. Both ends of the slide 23 are fixedly inserted with symmetrically arranged guide rods 213. The bracket 27 is slidably sleeved on the guide rods 213. The lower end of the bracket 27 is provided with symmetrically distributed guide holes 214. The guide rods 213 slide through the guide holes 214. The cooperation between the guide rods 213 and the guide holes 214 ensures the stable movement of the bracket 27. The top of the two brackets 27 is detachably equipped with a scraper 28. The scraper 28 can slide and fit against the top of the base 1.

[0020] By adopting the above technical solution, during use, rotating the two rotating rods 26 in sequence can drive the corresponding lead screw 24 to rotate through the corresponding rotating wheel 25, thereby driving the corresponding bracket 27 to move away from the base 1. This further allows the scraper 28 to be gradually tensioned and straightened, so that its bottom end is attached to the top of the base 1. During the operation of the photopolymer 3D printer, after the printing operation is completed, the electric cylinder body 21 is activated, which can drive the electric cylinder slider 22 to move to the other end of the base 1, thereby driving the carriage 23 to move to the other end of the base 1. This further allows the scraper 28 to move to the other end of the base 1 through the bracket 27, thereby enabling the 3D printed product to be easily and completely peeled off.

[0021] The limiting mechanism 3 includes a rotating ring 31. The upper end of the bracket 27 has an inner groove 29, and the rotating ring 31 is rotatably inserted into the inner groove 29. A torsion spring 32 is fixedly installed at the bottom end of the rotating ring 31, and the end of the torsion spring 32 is fixedly connected to the inner wall of the inner groove 29. A rotating shaft 33 is fixedly inserted into the middle of the rotating ring 31, and a convex block 34 is fixedly sleeved at the top end of the rotating shaft 33. Both ends of the shovel 28 have convex grooves 210 through them, and the convex block 34 can slide through the convex grooves 210. A handwheel 35 is rotatably inserted into one end of the convex block 34, and the outer wall of the handwheel 35 is covered with an anti-slip texture. A rotating hole 36 is through the convex block 34, and the handwheel 35 is rotatably inserted into the rotating hole 36. The anti-slip texture can increase friction and facilitate operation, and the cooperation between the handwheel 35 and the rotating hole 36 provides convenience for the rotation of the convex block 34.

[0022] By adopting the above technical solution, during use, both ends of the shovel 28 are respectively fitted onto the handwheel 35, and then the two handwheels 35 are rotated in sequence, thereby driving the corresponding convex block 34 to rotate. This, in turn, drives the corresponding rotating ring 31 to rotate through the corresponding rotating shaft 33 and twists the corresponding torsion spring 32. When the corresponding convex block 34 rotates 180 degrees, the convex groove 210 at the corresponding end of the shovel 28 is aligned with the corresponding convex block 34 and pressed down. When the corresponding convex block 34 separates from the convex groove 210, the corresponding handwheel 35 is released. Then, the torsion spring 32 will drive the corresponding convex block 34 to reverse and reset, thereby making the corresponding convex block 34 and the convex groove 210 completely misaligned. This allows for convenient and stable positioning and installation of the shovel 28. Furthermore, during subsequent use, the shovel 28 can be disassembled and replaced by reversing the above steps.

[0023] Working principle: In use, both ends of the shovel 28 are respectively fitted onto the handwheel 35. Then, the two handwheels 35 are rotated in sequence, which drives the corresponding convex block 34 to rotate. This drives the corresponding rotating ring 31 to rotate through the corresponding rotating shaft 33 and twists the corresponding torsion spring 32. When the corresponding convex block 34 rotates 180 degrees, the convex groove 210 at the corresponding end of the shovel 28 is aligned with the corresponding convex block 34 and pressed down. When the corresponding convex block 34 separates from the convex groove 210, the corresponding handwheel 35 is released. Then, the torsion spring 32 drives the corresponding convex block 34 to reverse and reset, so that the corresponding convex block 34 and the convex groove 210 are completely misaligned. This allows for convenient and stable installation of the shovel 28. In subsequent use, the shovel 28 can be disassembled and replaced by reversing the above steps.

[0024] Then, the two rotating rods 26 are rotated in sequence, which drives the corresponding lead screw 24 to rotate through the corresponding rotating wheel 25. This drives the corresponding bracket 27 to move away from the base 1. Furthermore, the scraper 28 is gradually tensioned and straightened so that its bottom end fits against the top of the base 1. During the operation of the photopolymer 3D printer, after the printing operation is completed, the electric cylinder body 21 is activated, which drives the electric cylinder slider 22 to move to the other end of the base 1. This drives the carriage 23 to move to the other end of the base 1. Furthermore, the scraper 28 is driven to the other end of the base 1 through the bracket 27, so that the 3D printed product can be easily and completely peeled off.

[0025] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
