Description

Technical Field

[0001] The utility model relates to the technical field of photosensitive resin processing, in particular to a resin recycling machine. Background Art

[0002] During the printing production process of SLA resin (laser-cured photosensitive resin), due to the characteristics of the process itself and the certain viscosity of the resin liquid, after the parts are printed, a thick layer of resin liquid will adhere to the surface of the parts and the resin support. Currently, the resin support is basically directly discarded. In this way, the residual resin liquid on its surface is directly wasted. In addition, in a small part of the prior art, the residual resin liquid on the resin support is recycled by the method of automatic placement and draining; however, due to the certain viscosity of the resin liquid, the effect of the automatic placement and draining recycling method is not very ideal, resulting in a large amount of waste of the resin liquid. Therefore, we propose an improvement to a resin recycling machine. Summary of the Utility Model

[0003] The purpose of the utility model is to improve and innovate in view of the disadvantages and problems in the background art, and provide a resin recycling machine.

[0004] A resin recycling machine includes a bottom plate. A barrel is rotatably connected to the bottom plate. The barrel is rotated by a motor drive mechanism. An inner liner is arranged inside the barrel. The inner liner is a filter mesh cylinder. Connecting plates are annularly and arrayedly distributed on the outer surface of the inner liner. The ends of the connecting plates are fixedly connected with connecting blocks. Limit grooves adapted to the connecting blocks are opened on the barrel. A first conical block is installed at the bottom of the inner liner, and a second conical block is installed at the bottom of the barrel.

[0005] Furthermore, a cover plate is arranged at the top of the barrel. The cover plate is snap-connected to the barrel through a snap mechanism. A rubber pad that fits the top end of the inner liner is arranged on the lower surface of the cover plate.

[0006] Furthermore, an annular groove is opened on the bottom wall of the barrel. A support column is installed on the bottom plate. The upper end of the support column is rotationally matched with the annular groove.

[0007] Furthermore, a circular ring is installed on the upper surface of the bottom plate. Rollers are respectively annularly and arrayedly arranged on the outer surface of the barrel. The rollers are in rolling fit with the inner surface of the circular ring.

[0008] Furthermore, the number of the connecting plates is set to four.

[0009] A further solution is that a support plate is installed on the outer surface of the barrel body, an electric telescopic rod is installed on the support plate, a communicating pipe is connected to the side wall of the barrel body, the liquid inlet of the communicating pipe is arranged at the bottom end of the first conical block, the end of the communicating pipe far away from the barrel body is fixedly communicated with a liquid outlet cylinder, a liquid discharge pipe is arranged on the bottom wall of the liquid outlet cylinder, a piston is slidably matched inside the liquid outlet cylinder, the output end of the electric telescopic rod is connected to the upper surface of the piston, and one-way valves are arranged on the communicating pipe and the liquid discharge pipe.

[0010] Compared with the prior art, the beneficial effects of the present utility model are as follows: (1) The present utility model provides a resin recovery machine. By placing the support with residual resin liquid in the inner tank, at this time, the motor drives the inner tank and the barrel body to rotate at a high speed through the transmission mechanism. Under the action of centrifugal force, the residual resin liquid on the support is thrown off and discharged through the mesh holes on the side wall of the inner tank. Since the second conical block is arranged on the bottom wall of the barrel body, when the resin liquid drops onto the second conical block, they will flow along the inclined surface of the cone to the bottom edge of the barrel body, so that the thrown resin liquid will gather at the bottom edge of the barrel body, which is convenient to be discharged from the barrel body through the communicating pipe;

[0011] (2) Through the mutual cooperation of the electric telescopic rod, the liquid outlet cylinder, the piston, the communicating pipe, the liquid discharge pipe and the one-way valve in the present utility model, when the electric telescopic rod drives the piston to move upward, the piston moves upward inside the liquid outlet cylinder, thereby forming a negative pressure area below it. This negative pressure area prompts the resin liquid inside the barrel body to be sucked into the liquid outlet cylinder, so as to overcome the viscous resistance of the resin liquid and ensure that the resin liquid smoothly enters the liquid outlet cylinder; when the electric telescopic rod drives the piston to move downward, the piston applies pressure to the resin liquid, which is convenient to discharge the resin liquid in the liquid outlet cylinder from the liquid outlet cylinder; therefore, problems such as large flow resistance and easy blockage during the flow of the resin liquid can be avoided.

[0019] Please refer to Figure 1 - Figure 2 , the present utility model provides a resin recovery machine, including a bottom plate 1, a barrel 3 is rotatably connected to one side of the bottom plate 1, and a motor 2 is installed on the other side of the bottom plate 1. The barrel 3 is driven by the motor 2 to rotate. Specifically, the output end of the motor 2 is fixedly connected with a driving wheel, a driven wheel is installed on the rotating shaft at the bottom end of the barrel 3, and the driving wheel is in transmission connection with the driven wheel through a conveyor belt. The motor 2 drives the driving wheel to rotate, and then drives the barrel 3 to rotate at a high speed.

[0020] An inner tank 4 is arranged inside the barrel 3. The inner tank 4 is a filter mesh cylinder. Connecting plates 6 are annularly and arrayedly distributed on the outer surface of the inner tank 4, and the number of the connecting plates 6 is set to four. The end of the connecting plate 6 is fixedly connected with a connecting block 7, and the connecting block 7 is a T-shaped block. A limiting groove 8 adapted to the connecting block 7 is formed on the barrel 3. Through the mutual cooperation of the limiting groove 8 and the connecting block 7, the barrel 3 can drive the inner tank 4 to rotate at a high speed, and at the same time, it is convenient to disassemble the inner tank 4 from the barrel 3 so as to load the support into the inner tank 4. After placing the support with residual resin liquid in the inner tank 4, at this time, the motor 2 drives the inner tank 4 and the barrel 3 to rotate at a high speed through a transmission mechanism. Under the action of centrifugal force, the residual resin liquid on the support is thrown off and discharged through the mesh holes on the side wall of the inner tank 4.

[0021] Preferably, a first handle is installed on the inner wall of the inner container 4, and holding the first handle facilitates the installation of the inner container 4 on the barrel body 3 and the removal of the inner container 4 from the barrel body 3.

[0022] Furthermore, a first conical block 9 is installed at the bottom of the inner container 4, and a second conical block 10 is installed at the bottom of the barrel body 3. When the resin liquid drops onto the first conical block 9 and the second conical block 10, they will flow along the inclined surface of the cone towards the bottom edges of the inner container 4 and the barrel body 3. The resin liquid gathered at the edge of the inner container 4 is easily thrown out under the action of centrifugal force, and the second conical block 10 is conducive to gathering the thrown-out resin liquid at the bottom edge of the barrel body 3.

[0023] A cover plate 5 is provided at the top end of the barrel body 3. The cover plate 5 is snap-connected to the barrel body 3 through a snap-fastening mechanism. A rubber pad that fits the top end of the inner container 4 is provided on the lower surface of the cover plate 5, so that the cover plate 5 can prevent the support in the inner container 4 from being thrown out during high-speed rotation.

[0024] Preferably, a second handle is installed on the upper surface of the cover plate 5 of the present application, and holding the second handle facilitates the handling of the cover plate 5.

[0025] An annular groove 11 is formed in the bottom wall of the barrel body 3, and a support column 12 is installed on the bottom plate 1. The upper end of the support column 12 is rotationally matched with the annular groove 11. Among them, the inner surface of the annular groove 11 is coated with lubricating oil. Through the rotational cooperation between the support column 12 and the annular groove 11, it plays a supporting role when the barrel body 3 rotates, making the rotation of the barrel body 3 stable.

[0026] Furthermore, a circular ring 13 is installed on the upper surface of the bottom plate 1. Roller wheels 14 are respectively arranged in a circular array on the outer surface of the barrel body 3, and the roller wheels 14 are in rolling cooperation with the inner surface of the circular ring 13. Through the mutual cooperation between the circular ring 13 and the roller wheels 14, the outer surface of the barrel body 3 maintains a sufficient contact area to make the rotation of the barrel body 3 more stable.

[0027] A support plate 15 is installed on the outer surface of the barrel body 3. An electric telescopic rod 16 is installed on the support plate 15. A communicating pipe 19 is connected to the side wall of the barrel body 3. The liquid inlet of the communicating pipe 19 is arranged at the bottom end of the first conical block 9. One end of the communicating pipe 19 away from the barrel body 3 is fixedly communicated with a liquid outlet cylinder 17. A liquid discharge pipe 20 is arranged on the bottom wall of the liquid outlet cylinder 17. A piston 18 is slidably fitted inside the liquid outlet cylinder 17. The output end of the electric telescopic rod 16 is connected to the upper surface of the piston 18. One-way valves 21 are arranged on the communicating pipe 19 and the liquid discharge pipe 20. The one-way valve 21 on the communicating pipe 19 can prevent the resin liquid in the liquid outlet cylinder 17 from flowing back into the barrel body 3, and the one-way valve 21 on the liquid discharge pipe 20 can prevent external air from entering the liquid outlet cylinder 17. When the electric telescopic rod 16 drives the piston 18 to move upward, the piston 18 moves upward inside the liquid outlet cylinder 17, thereby forming a negative pressure area below it. This negative pressure area causes the resin liquid inside the barrel body 3 to be sucked into the liquid outlet cylinder 17, so as to overcome the viscous resistance of the resin liquid and ensure that the resin liquid smoothly enters the liquid outlet cylinder 17. When the electric telescopic rod 16 drives the piston 18 to move downward, the piston 18 applies pressure to the resin liquid, facilitating the discharge of the resin liquid in the liquid outlet cylinder 17 from the liquid outlet cylinder 17. Therefore, problems such as large flow resistance and easy blockage during the flow of the resin liquid can be avoided.
