An ink supply device for green printing of a workpiece

Abstract

This utility model discloses an ink supply device for green printing of workpieces, relating to the printing field. The utility model includes a main body with a stirring shaft connected to the top center via a bearing. A tilting assembly is mounted on the stirring shaft. By incorporating the tilting assembly, when cleaning impurities from the filter screen, the operator first rotates the rotating shaft, causing a threaded column to rotate. This rotation of the threaded column then moves a threaded cylinder upwards, which in turn moves the stirring blades upwards. Once the threaded cylinder is in position, the operator pushes a locking pin using a push plate, causing the locking pin to move out of its locking hole. At this point, the locking pin no longer restricts the turntable. The operator can then rotate the movable shaft via the turntable, causing the mounting ring and filter screen to tilt 180°. Impurities on the filter screen will fall downwards and enter the discharge pipe through the discharge pipe, and then be discharged through the discharge pipe. This method allows for the rapid cleaning of impurities accumulated on the filter screen.

Description

Technical Field

[0001] This utility model relates to the printing field, specifically to an ink supply device for green printing of workpieces. Background Technology

[0002] Screen printing involves stretching silk, synthetic fiber, or metal mesh onto a frame and creating a screen printing plate using manual etched film or photochemical methods. Since ink is required for printing, an ink supply device is needed to supply the ink.

[0003] According to Chinese Patent Publication No. CN220053244U, a printing ink supply device is disclosed. This utility model sets up a stirring, cleaning and filtering structure in the cylinder of the ink supply device, and uses a stirring element to stir the ink in the cylinder to maintain the uniformity of the ink and avoid the sedimentation of particles in the ink.

[0004] Regarding the aforementioned disclosed patent content, a filter screen is provided to filter impurities in the ink, and a cleaning structure is provided to remove impurities from the filter screen and prevent them from clogging it. However, the cleaned impurities still accumulate around the filter screen, and over time, a large amount of impurities will accumulate on the filter screen. Since the filter screen is installed inside the device, it is difficult for workers to remove the impurities from the device, thereby reducing the cleaning efficiency of the accumulated impurities on the filter screen. Utility Model Content

[0005] Based on this, the purpose of this utility model is to provide an ink supply device for green printing of workpieces, so as to solve the technical problem of the inconvenience of discharging impurities accumulated on the filter screen from the inside of the device.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an ink supply device for green printing of workpieces, comprising a device body, a stirring shaft connected to the top center of the device body via a bearing, a flipping assembly on the stirring shaft, and the flipping assembly comprising a rotating shaft mounted on the stirring shaft via a bearing, limiting grooves opened on both sides of the stirring shaft, and a movable shaft mounted on one side inside the device body via a bearing, a mounting ring being installed at one end of the movable shaft, and one side of the mounting ring being connected to the device body via a connecting shaft, and a filter screen being provided inside the mounting ring, a turntable being provided at the other end of the movable shaft, the bottom end of the rotating shaft penetrating to the bottom of the stirring shaft and connected to a threaded column, and a threaded cylinder being sleeved on the outer wall of the threaded column.

[0007] By adopting the above technical solution, when it is necessary to clean the impurities on the filter screen, the staff can first rotate the shaft, so that the shaft drives the threaded column to rotate, and the rotation of the threaded column will drive the threaded cylinder to move upward.

[0008] Furthermore, a limiting block is provided inside the limiting groove, and one side of the limiting block is connected to the threaded cylinder.

[0009] By adopting the above technical solution, when the threaded cylinder moves, it will drive the limiting block to slide inside the limiting groove, thereby improving the stability of the threaded cylinder when it moves.

[0010] Furthermore, the flipping assembly also includes a groove on one side of the device body and two locking holes on the turntable. A spring is installed inside the groove, and one end of the spring is connected to a locking post extending to the outside of the device body.

[0011] By adopting the above technical solution, when the turntable needs to be rotated, the staff can push the locking pin so that the locking pin moves out of the locking hole. At this time, the locking pin no longer limits the turntable, and the turntable can be rotated.

[0012] Furthermore, one end of the locking pin is located inside a locking hole, and a push plate is fixed to the bottom of the locking pin.

[0013] By adopting the above technical solution, once the locking pin is inserted into a locking hole, the turntable can be limited to prevent it from rotating randomly.

[0014] Furthermore, a discharge pipe is connected to the bottom of the main body of the device, and a valve is installed on the discharge pipe.

[0015] By adopting the above technical solution, when ink needs to be discharged, the valve can be opened so that the ink can be discharged through the discharge pipe.

[0016] Furthermore, the bottom end of the discharge pipe is connected to a liquid discharge pipe and a material discharge pipe, respectively.

[0017] By adopting the above technical solution, the setting of the drain pipe facilitates the discharge of ink, while the setting of the discharge pipe facilitates the discharge of impurities.

[0018] Furthermore, the outer wall of the threaded cylinder is provided with multiple stirring blades, and the top of the limiting block is set with an inclined surface.

[0019] By adopting the above technical solution, when the threaded cylinder rotates, it will drive the stirring blade to rotate, and the stirring blade can agitate the ink.

[0020] Furthermore, a drive motor is installed on one side of the top of the main body of the device, and the output end of the drive motor is connected to a drive gear.

[0021] By adopting the above technical solution, when the stirring shaft needs to rotate, the drive motor will be activated, and the drive motor can drive the active gear to rotate.

[0022] Furthermore, a driven gear is sleeved on the upper part of the outer wall of the stirring shaft, and the driving gear meshes with the driven gear.

[0023] By adopting the above technical solution, when the driving gear rotates, it will drive the driven gear to rotate, and the driven gear will drive the stirring shaft to rotate.

[0024] Furthermore, the filter screen and the mounting ring are rotatably connected to the main body of the device via a movable shaft, and the outer wall of the mounting ring is in contact with the inner wall of the main body of the device.

[0025] By adopting the above technical solution, the rotating shaft can drive the mounting ring to flip, and then drive the filter screen to flip, so as to clean the impurities accumulated on the filter screen.

[0026] In summary, the present invention has the following main advantages:

[0027] This invention features a flipping assembly. When cleaning impurities from the filter screen, the operator first rotates the shaft, causing the threaded column to rotate. The rotation of the threaded column then moves the threaded cylinder upwards, which in turn moves the stirring blade upwards. Once the threaded cylinder is in position, the operator pushes the locking pin with a push plate, causing it to move out of the locking hole. At this point, the locking pin no longer restricts the turntable. The operator can then rotate the movable shaft via the turntable, causing the mounting ring and filter screen to flip 180°. The impurities on the filter screen will fall downwards and enter the discharge pipe through the discharge pipe, and then be discharged through the discharge pipe. This method can quickly clean the impurities accumulated on the filter screen without removing the filter screen, and the cleaning process is simple and convenient, thereby improving the cleaning efficiency of impurities accumulated on the filter screen.

[0034] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0035] The embodiments of this utility model will be described below based on its overall structure.

[0036] Example 1:

[0037] An ink supply device for green printing of workpieces, such as Figures 1-5 As shown, the device includes a main body 1. A stirring shaft 6 is connected to the top center of the main body 1 via a bearing. A tilting assembly 8 is provided on the stirring shaft 6. A discharge pipe 9 is connected to the bottom of the main body 1. A valve 10 is installed on the discharge pipe 9. When ink needs to be discharged, the valve 10 can be opened to allow the ink to be discharged through the discharge pipe 9. The bottom end of the discharge pipe 9 is connected to a drain pipe 11 and a discharge pipe 12. A drain valve is installed on the drain pipe 11 and a discharge valve is installed on the discharge pipe 12. The drain pipe 11 is designed to facilitate the discharge of ink, while the discharge pipe 12 is designed to facilitate the discharge of impurities.

[0038] See Figures 1-4 A drive motor 3 is installed on one side of the top of the main body 1. The output end of the drive motor 3 is connected to the drive gear 4. When the stirring shaft 6 needs to be rotated, the drive motor 3 will be started. The operation of the drive motor 3 can drive the drive gear 4 to rotate. A driven gear 5 is sleeved on the upper part of the outer wall of the stirring shaft 6. The drive gear 4 and the driven gear 5 mesh. When the drive gear 4 rotates, it will drive the driven gear 5 to rotate. The driven gear 5 will drive the stirring shaft 6 to rotate. A feed pipe 2 is connected to one side of the top of the main body 1 so that the ink can enter the interior of the main body 1 through the feed pipe 2.

[0039] Specifically, the flipping assembly 8 includes a rotating shaft 801 mounted on the stirring shaft 6 via bearings, limiting grooves 804 formed on both sides of the stirring shaft 6, and a movable shaft 808 mounted on one side of the device body 1 via bearings. One end of the movable shaft 808 is fitted with an installation ring 806, and one side of the installation ring 806 is connected to the device body 1 via a connecting shaft. A filter screen 807 is provided inside the installation ring 806. The filter screen 807 and the installation ring 806 are rotatably connected to the device body 1 via the movable shaft 808. The outer wall of the installation ring 806 fits against the inner wall of the device body 1 so that when the movable shaft 808 rotates, it can drive the installation ring 806 to flip, and then drive the filter screen 807 to flip, so as to clean the impurities accumulated on the filter screen 807. The distance between the filter screen 807 and the lower part of the device body 1 is greater than the radius of the filter screen 807.

[0040] Specifically, the other end of the movable shaft 808 is provided with a turntable 809. The bottom end of the rotating shaft 801 extends to the bottom of the stirring shaft 6 and is connected to a threaded column 802. A threaded cylinder 803 is sleeved on the outer wall of the threaded column 802. When it is necessary to clean the impurities on the filter screen 807, the operator can first rotate the rotating shaft 801, so that the rotating shaft 801 drives the threaded column 802 to rotate. After the threaded column 802 rotates, it drives the threaded cylinder 803 to move upward. A limit block 805 is provided inside the limiting groove 804 to limit the movement of the filter screen 807. One side of block 805 is connected to threaded cylinder 803. Threaded cylinder 803 is slidably connected to limiting groove 804 through limiting block 805. When threaded cylinder 803 moves, it will drive limiting block 805 to slide inside limiting groove 804, thereby improving the stability of threaded cylinder 803 when moving. Multiple stirring blades 7 are provided on the outer wall of threaded cylinder 803. The top of limiting block 805 is set with an inclined surface. When threaded cylinder 803 rotates, it will drive stirring blades 7 to rotate. Stirring blades 7 can agitate ink.

[0041] Example 2:

[0042] Based on the above embodiment 1, in order to prevent the turntable 809 from rotating arbitrarily and to improve the stability of the mounting ring 806 and the filter screen 807, it is necessary to limit the turntable 809. Therefore, the following structure will be set.

[0043] See Figures 2-4The flipping assembly 8 also includes a groove 813 on one side of the device body 1 and two locking holes 810 on the turntable 809. A spring 814 is installed inside the groove 813, and one end of the spring 814 is connected to a locking post 811 extending to the outside of the device body 1. When the turntable 809 needs to be rotated, the operator can push the locking post 811 so that the locking post 811 moves out of the locking hole 810. At this time, the locking post 811 no longer limits the turntable 809, and the turntable 809 can be rotated. One end of the locking post 811 is located inside one of the locking holes 810. A push plate 812 is fixed at the bottom of the locking post 811. When the locking post 811 is inserted into one of the locking holes 810, it can limit the turntable 809 and prevent the turntable 809 from rotating at will.

[0044] The working principle of this utility model is as follows: First, when using the device, the power is turned on. When the ink enters the main body 1 of the device through the feed pipe 2, the filter screen 807 inside the main body 1 can filter the ink. When it is necessary to stir the ink, the drive motor 3 can be started. The drive motor 3 can drive the active gear 4 to rotate, and then drive the driven gear 5 to rotate, and drive the stirring shaft 6 to rotate. The stirring shaft 6 drives the stirring blade 7 to rotate, so that the stirring blade 7 can stir the ink. When it is necessary to discharge the ink, the valve on the discharge pipe 9 can be opened, and the drain valve on the drain pipe 11 can be opened so that the ink enters the drain pipe 11 through the discharge pipe 9 and is discharged through the drain pipe 11.

[0045] When it is necessary to clean the impurities on the filter screen 807, open the discharge valve on the discharge pipe 12, and then rotate the rotating shaft 801, so that the rotating shaft 801 drives the threaded column 802 to rotate. After the threaded column 802 rotates, it drives the threaded cylinder 803 to move upward, and the threaded cylinder 803 drives the stirring blade 7 to move upward. When the threaded cylinder 803 moves into place, the operator pushes the locking column 811 to move through the push plate 812, so that the locking column 811 moves out of the locking hole 810. At this time, the locking column 811 no longer limits the turntable 809. Then the operator can rotate the movable shaft 808 through the turntable 809, and drive the mounting ring 806 and the filter screen 807 to rotate 180°. The impurities on the filter screen 807 will fall downward and enter the discharge pipe 12 through the discharge pipe 9, and then be discharged through the discharge pipe 12.
