Description

Technical Field

[0001] This utility model relates to the field of 3D printing technology, specifically to an automatic resin feeding tank for 3D printing. Background Technology

[0002] Photopolymer 3D printing technology is widely used in fields such as figurine making, dental medicine, and industrial prototypes due to its advantages of high precision and high molding quality. As the core component for storing and supplying photosensitive resin, the performance of the resin tank directly affects the printing efficiency and model quality.

[0003] The existing resin tanks mostly use a single-channel conveying system. When resin enters the resin tank through the port of a single channel, it is easy to form local resin accumulation, making it impossible to achieve uniform distribution along the length of the tank. When the conveying channel inputs resin into the resin tank, there is a lack of corresponding diversion structure, resulting in unstable resin flow speed, poor liquid surface flatness, and consequently, uneven model layer thickness.

[0004] To address the aforementioned problems, the inventor proposes a 3D-printed automatic resin suction tank. Utility Model Content

[0005] To address the problem of localized resin buildup after resin enters the resin tank through a single channel, the purpose of this invention is to provide an automatic resin suction tank for 3D printing.

[0006] To solve the above technical problems, the present invention adopts the following technical solution: a 3D printing automatic feeding resin tank, including a resin tank, with feeding mechanisms respectively provided at both ends of the resin tank, the feeding mechanisms feeding the resin tank into the interior in equal portions, and a peristaltic pump provided on the outer wall of the resin tank, the peristaltic pump being interconnected with the two feeding mechanisms.

[0007] The resin tank is provided with discharge ports at both ends, and discharge structures are provided at both ends. The discharge structures include a U-shaped plate for opening and closing the discharge ports of the resin tank and a spring for resetting the U-shaped plate.

[0008] A control mechanism is provided on the outer wall of the resin tank, which is used to control the discharge structure;

[0009] The resin tank is equipped with a pushing mechanism, which moves from one end of the resin tank to the other end to push the material inside the resin tank out.

[0010] Preferably, the peristaltic pump includes a pump body and a rotor. The pump body is connected to the outer wall of the resin tank, and the rotor is rotatably connected to the inner wall of the pump body. A servo motor is installed on the outer wall of the pump body, and a conveying pipe is provided on the inner wall of the pump body, the conveying pipe passing through the interior of the pump body.

[0011] Preferably, the material conveying mechanism includes a housing, an impeller, and a drive motor. The housing is fixedly connected to the outer wall of the resin tank, the impeller is rotatably connected to the inner wall of the housing, and a synchronous pulley is connected to the shaft of each of the two impellers. A synchronous belt drives between the two synchronous pulleys. A housing is fixedly connected to the outer wall of the resin tank, and the drive motor is mounted on the inner wall of the housing. The output shaft of the drive motor is connected to one of the synchronous pulleys. Several equidistant partitions are provided at the bottom of the housing.

[0012] Preferably, the U-shaped plate is slidably connected to the inner wall of the resin tank, the discharge port of the resin tank is set in an L-shape, the U-shaped plate closes the top port of the L-shape, and the spring is disposed between the bottom of the U-shaped plate and the inner wall of the resin tank.

[0013] Preferably, the control mechanism includes a regulating motor, regulating rods, and a base. The base is fixedly connected to the outer wall of the resin tank, the regulating motor is installed on the inner wall of the base, the two regulating rods are respectively fixedly connected to the outer wall of the output shaft of the regulating motor, a fixing block is fixedly connected to the outer wall of the U-shaped plate, and one end of the regulating rod pushes the U-shaped plate and the connecting block.

[0014] Preferably, the pushing mechanism includes a push plate, a lead screw, and an asynchronous motor. The asynchronous motor is installed on the bottom outer wall of the resin tank. The lead screw is rotatably connected to both ends of the bottom of the resin tank. The output shaft of the asynchronous motor is connected to one end of the lead screw. The push plate is slidably connected to the inner wall of the resin tank. The push plate extends to the bottom outer side of the resin tank. The lead screw passes through the bottom outer side of the push plate and is threaded.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0016] 1. The material conveying mechanism of this utility model realizes the synchronous rotation of the impellers at both ends through the drive motor, synchronous wheel and synchronous belt. Each pair of blades of the impeller forms an independent output cavity with the inner wall of the shell, which can carry an equal amount of resin and convey it stably. With the equidistant partitions at the bottom of the shell, the resin is diverted and evenly distributed along the length of the tank, thereby effectively avoiding local resin accumulation and ensuring the flatness of the liquid surface inside the resin tank.

[0017] 2. After printing is completed or when the resin is replaced, the asynchronous motor of the pushing mechanism drives the lead screw to rotate, which drives the push plate to move smoothly along the inner wall of the tank. This can completely push the residual resin in the tank to the discharge port of the resin tank for discharge and recycling, thus cleaning the residue inside the resin tank, avoiding cross-contamination between different types of resin, reducing the material scrap rate, and saving production costs.

[0029] 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.

[0030] Example

[0031] like Figure 1 - Figure 9 As shown, this utility model provides an automatic resin tank for 3D printing, including a resin tank 1. A feeding mechanism 3 is provided at both ends of the resin tank 1. The feeding mechanism 3 feeds the resin into the interior of the resin tank 1 in equal portions. A peristaltic pump 2 is provided on the outer wall of the resin tank 1. The peristaltic pump 2 is connected to the two feeding mechanisms 3. The peristaltic pump 2 is used to pump the resin raw material.

[0032] The resin tank 1 has discharge ports at both ends and discharge structures at both ends. The discharge structures include a U-shaped plate 6 for opening and closing the discharge ports of the resin tank 1 and a spring 7 for resetting the U-shaped plate 6.

[0033] A control mechanism 4 is provided on the outer wall of the resin tank 1. The control mechanism 4 is used to control the discharge structure.

[0034] A pushing mechanism 5 is provided on the resin tank 1. The pushing mechanism 5 moves along one end of the resin tank 1 to the other end of the resin tank 1 to push and discharge the material inside the resin tank 1.

[0035] Combination Figure 2 As shown, the peristaltic pump 2 includes a pump body 21 and a rotor 22. The pump body 21 is connected to the outer wall of the resin tank 1, and the rotor 22 is rotatably connected to the inner wall of the pump body 21. A servo motor 23 is installed on the outer wall of the pump body 21, and a conveying pipe 24 is provided on the inner wall of the pump body 21. The conveying pipe 24 passes through the interior of the pump body 21.

[0036] The purpose of this setup is to start the servo motor 23, whose output shaft drives the rotor 22 to rotate. The rotor 22 continuously squeezes the feed pipe 24 that runs through the pump body 21. The elastic deformation of the feed pipe 24 generates negative pressure, drawing photosensitive resin from the external storage bottle. Then, the resin is pushed by positive pressure to the feed mechanism 3 at both ends, thus completing the resin suction.

[0037] Combination Figure 3 - Figure 7As shown, the material conveying mechanism 3 includes a housing 31, an impeller 32, and a drive motor 35. The housing 31 is fixedly connected to the outer wall of the resin tank 1, and the impeller 32 is rotatably connected to the inner wall of the housing 31. Synchronous pulleys are respectively connected to the shafts of the two impellers 32, and a synchronous belt 34 is connected between the two synchronous pulleys. A housing is fixedly connected to the outer wall of the resin tank 1, and the drive motor 35 is installed on the inner wall of the housing. The output shaft of the drive motor 35 is connected to one of the synchronous pulleys. Several equidistant partitions 33 are provided at the bottom of the housing 31.

[0038] The purpose of this setup is to start the drive motor 35, whose output shaft drives the shaft of one of the impellers 32 to rotate. Through the transmission action of the synchronous pulley and the synchronous belt 34, the impellers 32 of the two-end conveying mechanisms 3 rotate synchronously. After the resin enters the housing 31, each pair of blades of the impeller 32 forms an output cavity with the inner wall of the housing 31, loading an equal amount of photosensitive resin. Then the impeller 32 rotates, conveying the photosensitive resin inside the output cavity to several equidistant partitions 33, which are used to divert and convey the resin to the inside of the resin tank 1 to prevent local accumulation.

[0039] Combination Figure 4 As shown, the U-shaped plate 6 is slidably connected to the inner wall of the resin tank 1. The discharge port of the resin tank 1 is set to L-shape. The U-shaped plate 6 closes the top port of the L-shape. The spring 7 is set between the bottom of the U-shaped plate 6 and the inner wall of the resin tank 1.

[0040] The purpose of this design is that when the inner wall of the resin tank 1 is filled with resin raw material, the tension of the spring 7 still supports the U-shaped plate 6, and the U-shaped plate 6 keeps the L-shaped top port of the resin tank 1 closed. The tension of the spring 7 is much greater than the pressure of the resin raw material. The opening of the port of the U-shaped plate 6 requires the control mechanism 4 to apply pressure.

[0041] Combination Figure 6 As shown, the control mechanism 4 includes a regulating motor 41, a regulating rod 42, and a base 43. The base 43 is fixedly connected to the outer wall of the resin tank 1. The regulating motor 41 is installed on the inner wall of the base 43. The two regulating rods 42 are respectively fixedly connected to the outer wall of the output shaft of the regulating motor 41. A fixing block is fixedly connected to the outer wall of the U-shaped plate 6. One end of the regulating rod 42 pushes the U-shaped plate 6 and the connecting block 61.

[0042] The purpose of this setup is that when the remaining resin needs to be discharged, the control motor 41 is started, which drives the two control rods 42 on its output shaft to rotate synchronously, either counterclockwise or clockwise. One end of the control rod 42 pushes the connecting block 61 of the U-shaped plate 6, causing the U-shaped plate 6 to overcome the elastic force of the spring 7 and slide downward along the inner wall of the resin tank 1, opening the closed L-shaped discharge port and providing a channel for resin discharge.

[0043] Combination Figure 8 and Figure 9 As shown, the feeding mechanism 5 includes a push plate 51, a lead screw 52 and an asynchronous motor 53. The asynchronous motor 53 is installed on the bottom outer wall of the resin tank 1. The lead screw 52 is rotatably connected to both ends of the bottom of the resin tank 1. The output shaft of the asynchronous motor 53 is connected to one end of the lead screw 52. The push plate 51 is slidably connected to the inner wall of the resin tank 1. The push plate 51 extends to the bottom outer side of the resin tank 1. The lead screw 52 passes through the bottom outer side of the push plate 51 and is threadedly connected.

[0044] The purpose of this setup is to start the asynchronous motor 53, whose output shaft drives the lead screw 52 to rotate. Since the lead screw is threadedly connected to the outer bottom of the push plate 51, it drives the push plate 51 to move. The push plate 51 moves smoothly along the inner wall of the resin tank 1 from one end to the other, completely pushing the residual resin in the tank to the open discharge port, thereby realizing the discharge and recycling of the resin.

[0045] Working principle: When resin raw materials need to be added into the resin tank 1, the servo motor 23 is started, and its output shaft drives the rotor 22 to rotate. The rotor 22 continuously squeezes the conveying pipe 24 that runs through the pump body 21. The elastic deformation of the conveying pipe 24 generates negative pressure, which draws photosensitive resin from the external storage bottle. Then, the resin is pushed by positive pressure to the conveying mechanism 3 at both ends to complete the suction of the resin.

[0046] Combination Figure 4 As shown, when the drive motor 35 is started, its output shaft drives the shaft of one of the impellers 32 to rotate. Through the transmission action of the synchronous pulley and the synchronous belt 34, the impellers 32 of the two-end conveying mechanism 3 rotate synchronously. After the resin enters the housing 31, each pair of blades of the impeller 32 and the inner wall of the housing 31 form an output cavity, which is loaded with an equal amount of photosensitive resin. Then the impeller 32 rotates, conveying the photosensitive resin inside the output cavity to several equidistant partitions 33.

[0047] When it is necessary to discharge the remaining resin, start the control motor 41, which drives the two control rods 42 on its output shaft to rotate synchronously, either counterclockwise or clockwise. One end of the control rod 42 pushes the connecting block 61 of the U-shaped plate 6, so that the U-shaped plate 6 overcomes the elastic force of the spring 7 and slides down along the inner wall of the resin tank 1, opening the closed L-shaped discharge port and providing a channel for resin discharge.

[0048] When the asynchronous motor 53 is started, its output shaft drives the lead screw 52 to rotate. Since the lead screw is threadedly connected to the outer bottom of the push plate 51, the push plate 51 is driven to move. The push plate 51 moves smoothly from one end to the other along the inner wall of the resin tank 1, pushing the residual resin in the tank to the open discharge port, thereby realizing the discharge and recycling of the resin.

[0049] All standard parts used in this utility model can be purchased from the market, and irregular parts can be customized according to the description and drawings. The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the prior art. The machinery, parts and equipment adopt conventional models in the prior art. In addition, the circuit connection adopts conventional connection methods in the prior art, which will not be described in detail here.

[0050] 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.
