Description

Technical Field

[0001] This utility model relates to the field of 3D printers, and more specifically, to a photopolymer 3D printer that is easy to clean. Background Technology

[0002] A photopolymer 3D printer is a device that uses photopolymer resin to rapidly cure and form a 3D model under light of a specific wavelength. During the 3D printing process, the printing platform continuously rises or falls, and the photopolymer resin solidifies and builds up layer by layer, eventually forming a three-dimensional model. However, after printing, a large amount of uncured photopolymer resin remains inside the printer, especially in the resin tank and printing platform. If not cleaned in time, this can not only affect the quality of subsequent prints but may also lead to equipment malfunction.

[0003] However, in some existing small photopolymer 3D printers, the printing platform is integrated with the printer, making it impossible to disassemble. While this connection method offers advantages such as simple structure, high stability, and guaranteed positional accuracy of the printing platform during printing, it presents challenges when cleaning residual resin from the platform. The tight connection between the platform and printer restricts the available space, making it difficult to thoroughly clean all parts of the platform. Consequently, dirt and resin on the platform surface are difficult to completely remove. Solving these problems has become a pressing issue for those skilled in the art. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a photopolymer 3D printer that is easy to clean, aiming to solve the problem that existing small photopolymer 3D printers cannot fully clean the printing platform because the printing platform and the printer are fixedly connected.

[0005] This utility model is implemented as follows:

[0006] This utility model provides a photopolymer 3D printer that is easy to clean, including a printer housing, a printing platform and a base. The printing platform is installed inside the printer housing, the base is fixedly connected to the inner wall of the printer housing, a stabilizing component is provided on the top of the base, and a traction component is provided on the inner wall of the printer housing.

[0007] The stabilizing component includes a moving plate, a material tray, a clamping component, a telescopic plate, a motor, a gear, a rack, and a slide bar. The moving plate is located on the top of the base, the material tray is located on the top of the moving plate, the clamping component is installed on the top of the moving plate, the telescopic plate is installed on the outer wall of the clamping component, the motor is fixedly connected to the bottom of the inner wall of the printer housing, the gear is installed at the output end of the motor, the rack is located inside the base, and the slide bar is fixedly connected to the bottom of the material tray.

[0008] Preferably, the bottom of the movable plate is slidably connected to the top of the base, and the bottom of the clamping member is slidably connected to the top of the movable plate.

[0009] By adopting the above technical solution, the movable plate can slide on the top of the base, and the clamping component can slide on the top of the movable plate to clamp and fix the material tray.

[0010] Preferably, one end of the telescopic plate penetrates through the outer wall of the clamping member and extends into the interior of the clamping member.

A spring is installed on the outer wall of the telescopic plate extending into the interior of the clamping member, and the side of the spring away from the telescopic plate is fixedly connected to the inner wall of the clamping member.

[0011] By adopting the above technical solution, the telescopic plate can slide inside the clamping component under the action of the spring, and at the same time play an auxiliary clamping role on the material tray, so that the clamping component can clamp and fix material trays of different sizes.

[0012] Preferably, the gear meshes with the rack, the top of the base has a notch and a slide rail, the top of the rack passes through the notch and is fixedly connected to the bottom of the movable plate, and the slide rod is located inside the slide rail and is slidably connected to the inner wall of the slide rail.

[0013] By adopting the above technical solution, when the motor starts, it can drive the rack through the gear to move, so that the rack pushes the moving plate to slide on the top of the base.

[0014] Preferably, the traction assembly includes a bent rod, a telescopic rod, and a fixed rod. The bent rod is disposed inside the printer housing, the telescopic rod is fixedly connected to the inner wall of the printer housing, and the fixed rod is fixedly connected to the outer wall of the clamping member.

[0017] Preferably, one end of the fixing rod passes through the bent rod and extends into the interior of the bent rod, and the outer wall of the fixing rod is slidably connected to the inner wall of the bent rod.

[0018] By adopting the above technical solution, when the telescopic rod compresses the air inside the bent rod, the compressed air will push the fixed rod, causing the fixed rod to push the clamping component to clamp and fix the material tray.

[0019] The beneficial effects of this utility model are:

[0020] 1. By setting up a moving plate and clamping components, after the material tray is placed on top of the moving plate, the telescopic plate will drive the clamping components to clamp and fix the material tray under the action of springs, ensuring the stability of the material tray during use. When it is necessary to disassemble the material tray, it can be removed from the outer wall of the clamping components simply by sliding it. This solves the problem that existing small photopolymer 3D printers cannot thoroughly clean the printing platform because the printing platform and the printer are fixedly connected.

[0021] 2. By setting up bending rods, telescopic rods, and fixed rods, when the moving plate moves, the telescopic rods will compress the air inside the bending rods, causing the compressed air to push the clamping parts to move through the fixed rods, increasing the clamping effect of the clamping parts on the material tray and further improving the stability of the material tray.

[0030] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0031] Reference Figures 1-6 A photopolymer 3D printer that is easy to clean includes a printer housing 1, a printing platform 2 and a base 3. The printing platform 2 is installed inside the printer housing 1, the base 3 is fixedly connected to the inner wall of the printer housing 1, a stabilizing component 4 is provided on the top of the base 3, and a traction component 5 is provided on the inner wall of the printer housing 1.

[0032] The stabilizing component 4 includes a movable plate 401, a material tray 402, a clamping member 403, a telescopic plate 404, a motor 405, a gear 406, a rack 407, and a slide bar 408. The movable plate 401 is disposed on the top of the base 3, and the bottom of the movable plate 401 is slidably connected to the top of the base 3, allowing the movable plate 401 to slide on the top of the base 3. The material tray 402 is disposed on the top of the movable plate 401, and the clamping member 403 is installed on the top of the movable plate 401. The bottom of the clamping member 403... The clamping member 403 is slidably connected to the top of the movable plate 401, and can slide on the top of the movable plate 401 to clamp and fix the material tray 402. A telescopic plate 404 is installed on the outer wall of the clamping member 403, with one end of the telescopic plate 404 penetrating through the outer wall of the clamping member 403 and extending into the interior of the clamping member 403. The outer wall of the telescopic plate 404 is slidably connected to the inner wall of the clamping member 403. A spring is installed on the outer wall of the telescopic plate 404 extending into the interior of the clamping member 403. The side away from the telescopic plate 404 is fixedly connected to the inner wall of the clamping member 403. The telescopic plate 404 can slide inside the clamping member 403 under the action of the spring, and at the same time play an auxiliary clamping role on the material tray 402, so that the clamping member 403 can clamp and fix material trays 402 of different sizes. The motor 405 is fixedly connected to the bottom of the inner wall of the printer housing 1. The gear 406 is installed at the output end of the motor 405. The rack 407 is set inside the base 3. The gear 406 meshes with the rack 407. The top of the base 3 has a notch and a slide rail. The top of the rack 407 passes through the notch and is fixedly connected to the bottom of the moving plate 401. When the motor 405 is started, it can drive the rack 407 to move through the gear 406, so that the rack 407 pushes the moving plate 401 to slide on the top of the base 3. The slide rod 408 is fixedly connected to the bottom of the material tray 402. The slide rod 408 is located inside the slide rail and is slidably connected to the inner wall of the slide rail.

[0033] By setting up a movable tray and clamping parts 403, after the tray 402 is placed on top of the movable plate 401, the telescopic plate 404 will drive the clamping parts 403 to clamp and fix the tray 402 under the action of the spring, ensuring the stability of the tray 402 during use. When it is necessary to disassemble the tray 402, it is only necessary to slide the tray 402 out of the outer wall of the clamping parts 403. This solves the problem that existing small photopolymer 3D printers cannot fully clean the printing platform 2 because the printing platform 2 is fixedly connected to the printer.

[0034] The traction assembly 5 includes a bent rod 501, a telescopic rod 502, and a fixed rod 503. The bent rod 501 is disposed inside the printer housing 1. A fixed ring is fixedly connected to the outer wall of the bent rod 501. The bottom of the fixed ring on the outer wall of the bent rod 501 is fixedly connected to the top of the moving plate 401. The outer wall of the bent rod 501 is slidably connected to the inner wall of the printer housing 1. When the moving plate 401 moves, it can drive the bent rod 501 to move inside the printer housing 1 through the fixed ring. The telescopic rod 502 is fixedly connected to the inner wall of the printer housing 1. The fixed rod 503 is fixedly connected to the outer wall of the clamping member 403. One end of the fixed rod 503 passes through the bent rod 501 and extends into the interior of the bent rod 501. The outer wall of the fixed rod 503 is slidably connected to the inner wall of the bent rod 501. When the telescopic rod 502 compresses the air inside the bent rod 501, the compressed air will push the fixed rod 503, causing the fixed rod 503 to push the clamping member 403 to clamp and fix the tray 402.

[0035] By setting up a bent rod 501, a telescopic rod 502, and a fixed rod 503, when the moving plate 401 moves, the telescopic rod 502 will compress the air inside the bent rod 501, causing the compressed air to push the clamping member 403 to move through the fixed rod 503, thereby increasing the clamping effect of the clamping member 403 on the material tray 402 and further improving the stability of the material tray 402.

[0036] The working principle of this easy-to-clean photopolymer 3D printer is as follows: When the material tray 402 needs to be removed from the printer, the operation of the motor 405 is controlled, causing the motor 405 to drive the gear 406 to rotate. Since the gear 406 meshes with the rack 407, the rotation of the gear 406 can drive the rack 407 to move, and the rack 407 can drive the moving plate 401 to slide on the top of the base 3. When the moving plate 401 moves on the top of the base 3, it will drive the bent rod 501 to slide on the surface of the telescopic rod 502 through the fixing ring. At this time, a negative pressure is generated inside the bent rod 501, and the clamping member 403 is pulled to slide through the fixing rod 503, so that the clamping member 403 separates from the material tray 402 until the moving plate 401 moves to the outside. At this time, the operator can remove the material tray 402 located on the top of the moving plate 401 and clean the resin residue inside the material tray 402.

[0037] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
