Description of the main element symbols:
the specific implementation mode is as follows:
the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Referring to fig. 1, the movable feeding system 100 includes a movable feeding device 1, a printing and molding device 2, and an intermediate material storage unit 3 disposed in the printing and molding device 2. The mobile feeding device 1 comprises a moving assembly 11, a material storage cylinder 12, a material transfer device 13 and a positioning device 14. The moving assembly 11 is arranged at the bottom of the moving feeding device 1 and used for driving the moving feeding device 1. The positioning device 14 is used for realizing the quick separation and combination of the mobile feeding device 1 and the printing and forming device 2. The intermediate material storage unit 3 is communicated and isolated with the movable feeding device 1 through a sealing device 4. When the mobile feeding device 1 is combined with the printing and forming device 2, the sealing device 4 is opened, and the material transfer device 13 conveys the material in the material storage cylinder 12 to the intermediate material storage unit 3. When the material in the material storage cylinder 12 is insufficient, the sealing device 4 is closed, the movable feeding device 1 is separated from the printing and forming device 2 and moves to a material filling area, and the printing and forming device 2 continues to use the material in the intermediate material storage unit 3. The powder spreading device 25 in the printing and forming device 2 sends the materials in the intermediate material storage unit 3 to a printing area for printing.
In particular, in this embodiment, the moving assembly 11 is configured to move the roller assembly, which is beneficial to reduce the frictional resistance when moving the feeding device 1. The positioning device 14 is disposed on a side of the mobile feeding device 1 facing the printing and forming device 2, a positioning groove 142 corresponding to the positioning device 14 is disposed on a side of the printing and forming device 2 facing the mobile feeding device 1, and an in-place detector 141 is disposed therein. When the mobile feeding device 1 is combined with the printing and molding device 2, the positioning device 14 is accommodated in the positioning groove 142 and activates the in-position detector 141.
The mobile feeding device 1 further comprises a material transfer bin 15, when the mobile feeding device 1 is combined with the printing and forming device 2, the material transfer bin 15 is in butt joint with the intermediate material storage unit 3, and the intermediate material storage unit 3 is arranged below the material transfer bin 15. The sealing device 4 comprises a sealing switch 41 and a sealing valve 42, the sealing valve 42 is arranged between the material transfer bin 15 and the intermediate material storage unit 3, and the sealing switch 41 is electrically connected with the sealing valve 42 and used for controlling the opening and closing of the sealing valve 42. A feeding piston 121 and a first driving device 17 in transmission connection with the feeding piston 121 are arranged in the material storage cylinder 12. The first driving device 17 drives the feeding piston 121 to move upwards from the bottom of the material storage cylinder 12, and the material is fed to the material transfer device 13 at the upper end of the material storage cylinder 12. The end of the feed piston 121 in contact with the material can seal the bottom of the material storage cylinder 12 to prevent the material from falling into the first drive means 17.
The material transfer device 13 transfers the material conveyed by the feeding piston 121 to the material transfer bin 15, and when the sealing valve 42 is opened, the material in the material transfer bin 15 falls to the intermediate material storage unit 3. When the feeding piston 121 moves to the highest position, the materials in the material storage cylinder 12 are used up, the sealing switch 41 controls the sealing valve 42 to be closed, the movable feeding device 1 is separated from the printing and forming device 2 under the movement of workers or other mechanical equipment and is conveyed to a material supplementing area, and the printing and forming device 2 continues to use the materials stored in the intermediate material storage unit 3 to perform printing work, so that the movable feeding device 1 has the time for filling the materials. And after the mobile feeding device 1 is supplemented with the materials, the mobile feeding device returns to the original position to be combined with the printing and forming device 2, and the feeding process is continued.
Further, a high level detector 31 is arranged at a position close to the upper end of the intermediate material storage unit 3, a low level detector 32 is arranged at a position close to the lower end of the intermediate material storage unit 3, and both the high level detector 31 and the low level detector 32 are used for detecting and judging the amount of the material in the intermediate material storage unit 3. When the high level detector 31 detects the material, which indicates that the intermediate material storage unit 3 is full of material, the sealing switch 41 controls the sealing valve 42 to close, so as to block the material from entering the intermediate material storage unit 3. When the low level detector 32 does not detect the material, indicating that the material in the intermediate material storage unit 3 is lacking, the sealing switch 41 controls the sealing valve 42 to open, and the material in the material transfer bin 15 enters the intermediate material storage unit 3. The printing and forming device 2 comprises a powder spreading device 25 arranged below the intermediate material storage unit 3 and used for conveying materials to the printing station 22 for printing. The lower end of the middle material storage unit 3 is provided with a blanking switch 33, when the powder paving device 25 moves below the blanking switch 33, the blanking switch 33 puts down quantitative materials into the powder paving device 25, then the powder paving device 25 sends the materials to the printing station 22, and powder is paved according to a preset rule. During the three-dimensional printing process, the powder laying device 25 reciprocates between the printing station 22 and the intermediate material storage unit 3. A sensor can also be provided at the sealing valve 42 for detecting that the material transfer bin 15 of the mobile feeding device 1 has reached the correct position.
In another embodiment, when the high level detector 31 detects material, indicating that the intermediate material storage unit 3 is full, the sealing switch 41 controls the sealing valve 42 to close, blocking the material from entering the intermediate material storage unit 3. When the high level detector 31 does not detect material, indicating that the intermediate material storage unit 3 can be filled with material, the sealing switch 41 controls the sealing valve 42 to open, allowing material to enter the intermediate material storage unit 3. When the low level detector 32 does not detect the material, the low level detector 32 sends out an alarm signal to remind the staff to check the feeding condition and replenish the material as soon as possible, which indicates that the material in the middle material storage unit 3 is about to be used up.
Preferably, the printing and molding device 2 further comprises a printing piston 21 and a second driving device 24 in transmission connection with the printing piston 21, wherein the second driving device 24 is used for driving the printing piston 21 to move up and down. When the printing piston 21 is at the highest position, the position of the top surface of the printing piston 21 is the printing station 22. In this embodiment, the three-dimensional printing is hierarchical printing, and each time the powder spreading device 25 sends a material to the printing station 22, the printing and forming device 2 performs one-time processing on the material at the printing station 22, for example, sintering the material, and completes one-level printing. With the three-dimensional printing operation, each time a printing station of one level is completed, the second driving device 24 drives the printing piston 21 to move downward by a corresponding distance until the printing operation is completed. The printing height is consistent with the feeding height, the feeding time is shortened, and the printing efficiency is improved.
In order to ensure the printing quality, the oxygen content in the printing and molding apparatus 2 needs to be controlled below a predetermined value. A first oxygen removal unit 16 and a second oxygen removal unit 23 are further arranged in the mobile feeding device 1 and the printing and forming device 2 respectively and used for independently detecting the oxygen content in the mobile feeding device 1 and the printing and forming device 2 and removing redundant oxygen. The oxygen removing method of the embodiment is that the first oxygen removing unit 16 and the second oxygen removing unit 23 respectively fill inert gas with density higher than that of air into the mobile material supply device 1 and the printing and forming device 2, and excess air is discharged from the device through a physical method, so that the oxygen concentration in the device is reduced. The first oxygen removing unit 16 and the second oxygen removing unit 23 may be set to detect the oxygen removing mode in real time, or may be set to detect the oxygen removing according to a specific program, which is not limited in this embodiment.
Further, referring to fig. 2, the movable feeding system 100 further includes a controller 5, and the controller 5 is electrically connected to the material transfer device 13, the first driving device 17, the second driving device 24, the powder spreading device 25, and the sealing switch 41, respectively.
The invention also provides a feeding method, which comprises the following steps:
step 1: the movable feeding device 1 is combined with the printing and forming device 2, the sealing device 4 is opened, and the material transfer bin 15 of the movable feeding device 1 is communicated with the intermediate material storage unit 3 in the printing and forming device 2.
Specifically, when the mobile feeding device 1 is combined with the printing and molding device 2, the controller 5 determines whether the mobile feeding device 1 is in place or not according to a signal sent by the in-place detector 141. The controller 5 is in signal connection with the first oxygen removing unit 16 and the second oxygen removing unit 23, and before the sealing device 4 is opened, the controller 5 sends signals to the first oxygen removing unit 16 and the second oxygen removing unit 23 respectively to control the first oxygen removing unit and the second oxygen removing unit to remove oxygen from the mobile feeding device 1 and the printing and forming device 2 respectively. When the oxygen content detected by the first oxygen removing unit 16 and the second oxygen removing unit 23 is lower than a predetermined value, the controller 5 sends a signal to the sealing switch 41, and the sealing switch 41 controls the sealing valve 42 to be opened according to the received signal.
Step 2: the first driving device 17 drives the feeding piston 121 to move upwards, the material transfer device 13 conveys the material conveyed by the feeding piston 121 to the material transfer bin 15, the material enters the intermediate material storage unit 3 through the sealing valve 42, and the intermediate material storage unit 3 quantitatively conveys the material to the powder spreading device 25 through the discharging switch 33.
Specifically, the high level detector 31 and the low level detector 32 are respectively signal-connected to the sealing switch 41. When the high level detector 31 detects the material, the high level detector 31 sends a full material signal to the sealing switch 41, and the sealing switch 41 controls the sealing valve 42 to close. When the material in the intermediate material storage unit 3 is reduced to the low level detector 32 and the material cannot be detected, the low level detector 32 sends a material shortage signal to the sealing switch 41, the sealing switch 41 controls the sealing valve 42 to be opened, and the material in the material transfer bin 15 is filled into the intermediate material storage unit 3.
And step 3: the controller 5 controls the powder spreading device 25 to send the materials to the printing station 22, powder is spread according to a preset rule, and after the powder spreading is completed, the controller 5 controls the powder spreading device 25 to return to the position below the discharging switch 33 to wait for receiving new materials.
Specifically, the blanking switch 33 can detect whether the powder spreading device 25 is in place, if the powder spreading device 25 is in place, the blanking switch 33 is turned on to quantitatively release the material into the powder spreading device 25, and if the powder spreading device 25 is not in place, the blanking switch 33 is kept turned off.
And 4, step 4: after the first driving device 17 drives the feeding piston 121 to move to the highest position, a high potential signal is sent to the controller 5, the controller 5 sends a signal to the sealing switch 41 again, and the sealing switch 41 is controlled to close the sealing valve 42.
Specifically, after the first driving device 17 sends a high potential signal to the controller 5, the controller 5 controls the first driving device 17 to drive the feeding piston 121 to move reversely (move downward) according to the received signal, so as to recover the volume of the material storage cylinder 12.
And 5: the mobile feeding device 1 is separated from the printing and forming device 2 and moves to a material filling area.
Specifically, the mobile feeding device 1 moves to the original position after the completion of the material filling, re-engages with the mobile feeding device 1, and repeats the previous feeding step. Before the mobile feeding device 1 is combined with the mobile feeding device 1 again, the printing and forming device 2 uses the materials in the intermediate material storage unit 3 to perform printing work, and continuous and uninterrupted printing work is guaranteed. When the mobile feeder 1 is separated, the controller 5 keeps the sealing valve closed by the sealing switch 41 even if the low level detector 32 determines that the material in the intermediate material storage unit is insufficient. When the low level detector 32 cannot detect the material, the material remaining in the intermediate material storage unit 3 is sufficient to support the print forming apparatus 2 until the mobile feeder 1 is re-engaged with the mobile feeder 1.
Although the present invention has been described in detail with reference to the preferred embodiments, it will be understood by those skilled in the art that various changes may be made and equivalents may be substituted without departing from the spirit and scope of the invention.
