Description

Technical Field

[0001] This utility model belongs to the field of 3D printing technology, specifically a scraper demolding support frame for 3D printing. Background Technology

[0002] 3D printing, also known as additive manufacturing, is a technology that manufactures solid parts by adding materials layer by layer based on three-dimensional data. From its early days as a rapid prototyping technology to its current widespread application, 3D printing technology has been applied in design and manufacturing fields such as jewelry design, footwear design and manufacturing, industrial design, architectural design, engineering design and construction, and automobile design and manufacturing, as well as in medical fields such as aerospace and dentistry.

[0003] In real-world 3D printing, the bottom of the printed parts is usually supported by numerous supports to ensure smooth printing and prevent collapse. Some parts do not require supports because they have sufficient supporting surfaces at their bottom. However, these supports or the flat surfaces of the parts themselves can cause severe adhesion to the 3D printing platform after printing. In such cases, a scraper is needed in conjunction with a support frame to help with demolding. When using a scraper for demolding, care must be taken to avoid damaging the parts. In reality, demolding is often done manually using a scraper, which results in relatively low demolding efficiency. Utility Model Content

[0004] To address the problems mentioned in the background section, this invention provides a 3D printing scraper demolding support frame, which has the advantage of assisting in the demolding of printed parts. This invention solves the problem of printed parts easily sticking to the printing platform through the interaction between the internal scraper and the support frame, allowing for quick removal of parts from the printing platform and addressing the low efficiency of manual demolding, thereby improving work efficiency and reducing manpower consumption.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a scraper demolding support frame for 3D printing, comprising a printer housing, with first slide rails fixedly arranged on both sides of the printer housing, a first slider slidably arranged on the top surface of the first slide rail, a support frame body fixedly arranged on the top surface of the first slider, a fixed frame fixedly arranged on the inner side of the support frame body, a first motor fixedly arranged on the outer side of the support frame body, a threaded shaft fixedly arranged at the end of the main shaft of the first motor, a sliding block threadedly connected to the outer side of the threaded shaft, the sliding block sliding inside the fixed frame, and a scraper body slidably arranged inside the sliding block.

[0006] Preferably, a fixing frame is slidably provided on the outer side of the fixing frame, and a second motor is fixedly provided on the outer side of the fixing frame. A threaded rod is fixedly provided at the end of the main shaft of the second motor, and the threaded rod is threadedly connected to the scraper body.

[0007] Preferably, a synchronous pulley assembly is rotatably mounted on the outer side of the main shaft of the second motor, and another threaded rod is fixedly mounted inside the other side of the synchronous pulley assembly.

[0008] Preferably, a plurality of second sliders are fixedly provided on the bottom surface of the fixing frame, and a second slide rail is slidably provided inside the second slider, and the second slide rail is fixedly connected to the fixing frame.

[0009] Preferably, a plurality of connecting plates are fixedly arranged on the inner side of the support frame body, a plurality of fixing sleeves are fixedly arranged on the outer side of the connecting plates, a sliding sleeve is slidably arranged inside the fixing sleeve, and a suction cup is fixedly arranged on the outer side of the sliding sleeve.

[0010] Preferably, a spring is fitted on the outer side of the sliding sleeve, and one side of the spring is fixedly connected to the fixed sleeve, while the other side is fixedly connected to the sliding sleeve.

[0011] Preferably, a printing table is fixedly provided on the inner bottom surface of the printer housing, and the printing table is in contact with the scraper body.

[0012] Preferably, the printer housing has a rotating door on its outer side, and the rotating door has a transparent window inside.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] 1. This utility model can quickly demold parts from the printing platform using the scraper body. At the same time, the first motor drives the threaded shaft to rotate, which in turn drives the sliding block to move, thereby causing the scraper body to move back and forth. At this time, the scraper body acts like a saw, thus handling some stubborn support bars and more serious adhesion situations. It solves the problem that printed parts are easy to stick to the printing platform, can quickly remove parts from the printing platform, and eliminates the problem of low efficiency when demolding manually, thereby improving work efficiency and reducing manpower consumption.

[0015] 2. In this utility model, the support frame body slides on the top surface of the first slide rail, which simultaneously drives the fixed sleeve on the top surface of the connecting plate to move. The fixed sleeve drives the suction cup at the front end to move. When the suction cup comes into contact with the part, it can hold the part in place, preventing it from collapsing during demolding and ensuring the integrity of the part.

[0022] 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.

[0023] like Figures 1 to 5As shown, this utility model provides a 3D printing scraper demolding support frame, including a printer housing 1. First slide rails 2 are fixedly installed on both sides of the inside of the printer housing 1. A first slider 3 is slidably installed on the top surface of the first slide rail 2. A support frame body 4 is fixedly installed on the top surface of the first slider 3. A fixing frame 5 is fixedly installed on the inner side of the support frame body 4. A first motor 6 is fixedly installed on the outer side of the support frame body 4. A threaded shaft 7 is fixedly installed at the end of the main shaft of the first motor 6. A sliding block 8 is threadedly connected to the outer side of the threaded shaft 7. The sliding block 8 slides inside the fixing frame 5. The internal sliding mechanism includes a scraper body 9. As the scraper body 9 moves, it quickly demolds the parts from the printing platform. Simultaneously, the first motor 6 drives the threaded shaft 7 to rotate, which in turn drives the sliding block 8 to move. This causes the scraper body 9 to reciprocate. In this case, the scraper body 9 acts like a saw, effectively handling stubborn support bars and severe adhesion issues. This solves the problem of printed parts easily sticking to the printing platform, allowing for quick removal of parts from the printing platform and reducing the inefficiency of manual demolding. As a result, work efficiency is improved and manpower consumption is reduced.

[0024] Specifically, a fixed frame 12 is slidably mounted on the outside of the fixed frame 5, and a second motor 13 is fixedly mounted on the outside of the fixed frame 12. A threaded rod 14 is fixedly mounted at the end of the main shaft of the second motor 13, and the threaded rod 14 is threadedly connected to the scraper body 9. If the product is larger at the top and smaller at the bottom, resulting in insufficient distance for the scraper body 9, the switch of the second motor 13 can be turned on. The second motor 13 drives the threaded rod 14 to rotate, and the rotation of the threaded rod 14 drives the scraper body 9 to move forward, and then scrapes the part off the surface of the printing platform.

[0025] Furthermore, a synchronous pulley assembly 15 is rotatably mounted on the outer side of the main shaft of the second motor 13, and another threaded rod 14 is fixedly mounted inside the other side of the synchronous pulley assembly 15. The threaded rods 14 on both sides run simultaneously, thereby maintaining the synchronicity of the movement of the scraper body 9 and the uniformity of the force on the parts.

[0026] Furthermore, a plurality of second sliders 11 are fixedly provided on the bottom surface of the fixed frame 12, and a second slide rail 10 is slidably provided inside the second slider 11. The second slide rail 10 is fixedly connected to the fixed frame 5. The second sliders 11 can not only ensure the stability of the fixed frame 12, but also move more smoothly through cooperation with the second slide rail 10.

[0027] It is worth noting that multiple connecting plates 16 are fixedly installed on the inner side of the support frame body 4, and multiple fixing sleeves 17 are fixedly installed on the outer side of the connecting plates 16. A sliding sleeve 18 is slidably installed inside the fixing sleeve 17, and a suction cup 19 is fixedly installed on the outer side of the sliding sleeve 18. The suction cup 19 is used to hold the parts, thereby preventing the parts from collapsing when helping to demold.

[0028] It is worth noting that a spring 20 is fitted on the outer side of the sliding sleeve 18, and one side of the spring 20 is fixedly connected to the fixed sleeve 17, and the other side is fixedly connected to the sliding sleeve 18. The spring 20 is used to adjust the length of the sliding sleeve 18, so that the suction cup 19 can better fit the printed product.

[0029] It is worth mentioning that a printing table 22 is fixedly installed on the bottom surface of the printer housing 1, and the printing table 22 is attached to the scraper body 9. The printing table 22 is used to place the printed products.

[0030] It is worth emphasizing that the printer housing 1 has a rotating door 21 on its outer side, and the inside of the rotating door 21 has a transparent window, so that the staff can more intuitively observe the printing status of the product through the transparent window during printing.

[0031] The first motor 6 and the second motor 13 are existing technologies and will not be described in detail. Additionally, this utility model also includes a power supply, controller, and switches, which are not the main technical points of this patent and will not be described in detail. The "front, rear, left, and right" perspectives of this device are... Figure 1 The direction shown in the diagram is the reference.

[0032] Working principle:

[0033] When using a 3D printing scraper demolding support frame, firstly, the power supply inside the printer housing 1 drives the first slider 3 to slide along the first slide rail 2. Simultaneously, the first slider 3 moves, causing the support frame body 4 to move. The support frame body 4 then moves the connecting plate 16, which in turn moves the fixing sleeve 17. The suction cup 19 moves the sliding sleeve 18, which in turn moves the suction cup 19. The suction cup 19 then contacts the part, holding it in place and preventing it from collapsing during demolding. The spring 20 adapts to the shape of the part. Demolding is then performed by the scraper body 9. If the part is severely adhered, the first motor 6 is switched on. The first motor 6 drives the threaded shaft 7 to rotate, which in turn moves the sliding block 8 inside the fixing frame 5. The sliding block 8 then moves the scraper body 9, which then acts like a saw to handle stubborn adhesions. For products with a large top and small bottom, resulting in insufficient distance for the scraper body 9, the switch of the second motor 13 on the outside of the fixing frame 12 can be turned on. The fixing frame 12 slides on the top surface of the second slide rail 10 via the second slider 11, which also serves to fix the fixing frame 12. The second motor 13 drives the threaded rod 14 to rotate, and the synchronous wheel assembly 15 drives the threaded rod 14 on the other side to rotate, thereby moving the scraper body 9 forward. Then, the part is scraped off the surface of the printing table 22. The rotating door 21 is used to observe the printing product during printing. This utility model solves the problem of printed parts easily sticking to the printing platform through the interaction of the internal scraper and the supporting frame. It can quickly remove the parts from the printing platform and eliminate the low efficiency of manual demolding, thereby improving work efficiency and reducing manpower consumption.
