[0027] like Figures 1 to 4 As shown, a screening device for granule drug processing comprises a processing box 1, a material guide port is provided on the upper surface of the processing box 1, a feeding funnel 2 is installed inside the material guide port of the processing box 1, a control panel 3 is provided on the front of the processing box 1, a card slot is provided on the inner wall of the back of the processing box 1, a screening mechanism 7 capable of accurately screening granules is slidably connected inside the card slot of the processing box 1, a driving mechanism 8 for driving the screening mechanism 7 to move is provided at the bottom of the inner wall of the processing box 1, two groups of grooves are provided on the right side of the processing box 1, and a material guide mechanism 4 is clamped inside the two groups of grooves of the processing box 1;

[0028] Specifically, the upper surface of the screening mechanism 7 is set as an inclined surface, so that the granules falling from the processing box 1 to the upper surface of the screening mechanism 7 are tilted along the upper surface of the screening mechanism 7 toward the right side of the upper end of the screening mechanism 7, thereby avoiding as much as possible the granules falling from the processing box 1 to the upper surface of the screening mechanism 7 to accumulate at a point on the upper surface of the screening mechanism 7, causing the upper end of the screening mechanism 7 to sink due to excessive accumulation of granules, causing the screening mechanism 7 to deform; the driving mechanism 8 is started to drive the screening mechanism 7 to move up and down inside the card slot of the processing box 1, and the driving mechanism 8 is set inside the processing box 1, so that the external air of the processing box 1 cannot enter the interior of the processing box 1 when the driving mechanism 8 drives the screening mechanism 7 to move up and down, thereby avoiding as much as possible the granules from being polluted by air during the screening process.

[0029] like Figure 1 and Figure 2As shown, the screening mechanism 7 includes two groups of U-shaped fixing plates 701, both of which are slidably connected to the inside of the card slot of the processing box 1, and the upper surfaces of the two groups of U-shaped fixing plates 701 are provided with U-shaped support plates, and the inner tops of the two groups of U-shaped support plates are provided with through holes, and driving rods 704 are installed inside the through holes of the two groups of U-shaped support plates, and the interiors of the two groups of U-shaped fixing plates 701 are provided with screens 702, and the upper surfaces of the two groups of screens 702 are provided with grooves. The inner walls of the grooves of the two groups of screens 702 are installed on the outer surface of the driving rod 704, and the upper surfaces of the two groups of U-shaped fixing plates 701 are provided with inclined surfaces. The inclined surfaces of the upper surfaces of the two groups of U-shaped fixing plates 701 are inclined downward from left to right. The heights of the bottoms of the inner walls of the two groups of grooves of the processing box 1 are respectively parallel to the heights of the upper surfaces of the right sides of the two groups of U-shaped fixing plates 701, and the heights of the upper surfaces of the two groups of screens 702 are respectively parallel to the heights of the upper inclined surfaces of the two groups of U-shaped fixing plates 701;

[0030] Specifically, after the granules are poured into the processing box 1 along the feeding funnel 2, the driving rod 704 is pulled to drive the two sets of U-shaped support plates to pull the two sets of U-shaped fixing plates 701 to move up and down in the slot of the processing box 1, so that the top set of screens 702 vibrate and screen the granules accumulated on the upper surface, and then the position of the screen 702 is set inside the U-shaped fixing plate 701, so that the U-shaped fixing plate 701 restricts the use of the screen 702, thereby avoiding the screen 702 from screening the granules as much as possible. The deformation occurs during the process, causing the inner diameter of the sieve holes inside the screen 702 to expand or shrink, thereby improving the accuracy of the device in screening granules; by setting the upper surface of the screen 702 as an inclined surface, the granules falling from the processing box 1 to the upper surface of the screen 702 are tilted along the upper surface of the screen 702 toward the right side of the upper end of the screen 702, thereby avoiding the granules falling from the processing box 1 to the upper surface of the screen 702 from accumulating at a point on the upper surface of the screen 702, causing the upper end of the screen 702 to sink due to excessive accumulation of granules.

[0031] like Figure 2 and Figure 4 As shown, the driving mechanism 8 includes a fixed rod 802 and a motor 801. A positioning groove is provided on the side of the processing box 1 close to the material guide mechanism 4. The fixed rod 802 is slidably connected inside the positioning groove of the processing box 1. The motor 801 is installed at the bottom of the inner wall of the processing box 1. A push rod 805 is provided on the side of the fixed rod 802 away from the material guide mechanism 4. A fixed disc 803 is installed on the output shaft of the motor 801. A groove is provided on the side of the fixed disc 803 away from the motor 801. A connecting rod 804 is rotatably connected inside the groove of the fixed disc 803. The side of the connecting rod 804 away from the fixed disc 803 is hinged to the side of the push rod 805 close to the motor 801.

[0032] Specifically, the motor 801 is started to drive the fixed disc 803 to trigger the connecting rod 804 to pull the top rod 805 to move up and down reciprocatingly, and then the driving rod 704 is installed on the upper surface of the top rod 805, so that the driving mechanism 8 accelerates during the startup process to drive the driving rod 704 to drive the two groups of screens 702 to move up and down reciprocatingly, thereby improving the screening efficiency of the two groups of screens 702 when screening granules, thereby improving the practicality of the device; the fixed rod 802 is installed on one side of the top rod 805, so that the fixed rod 802 limits the moving path of the top rod 805, thereby avoiding the position of the top rod 805 from being offset during the up and down movement; the driving mechanism 8 is started to drive the screening mechanism 7 to move up and down reciprocatingly inside the card slot of the processing box 1, and then the driving mechanism 8 is arranged inside the processing box 1, so that the external gas of the processing box 1 cannot enter the inside of the processing box 1 when the driving mechanism 8 pushes the screening mechanism 7 to move up and down reciprocatingly, thereby avoiding the granules from being polluted by air during the screening process.

[0033] like Figures 1 to 3 As shown, the two sets of material guide mechanisms 4 both include hinges 402, and the two sets of hinges 402 are respectively installed on the outer surface of one side of the processing box 1 close to the driving mechanism 8, and the outer surface of one side of the processing box 1 close to the driving mechanism 8 is hinged with two sets of material guide plates 401 through the two sets of hinges 402. The positions of the two sets of grooves in the processing box 1 are respectively located on the rotation paths of the two sets of material guide plates 401, and the upper surfaces of the two sets of material guide plates 401 are both provided with two sets of limiting plates 403, and the opposite sides of the two adjacent sets of limiting plates 403 are respectively abutted against the front and rear inner walls of the grooves of the processing box 1, and the heights of the upper surfaces of the two sets of material guide plates 401 are respectively the same as the heights of the bottoms of the inner walls of the two sets of grooves in the processing box 1;

[0034] Specifically, when the device is idle, by pushing the two sets of guide plates 401, the opposite sides of the two adjacent limit plates 403 are respectively abutted against the front and rear inner walls of the grooves of the processing box 1, so that the positions of the two sets of guide plates 401 are clamped on the side of the processing box 1 close to the driving mechanism 8, and then the two sets of guide plates 401 cover the exposed parts of the two sets of grooves of the processing box 1, thereby minimizing the dust from entering the interior of the processing box 1 along the two sets of grooves of the processing box 1 during the subsequent idle storage of the processing box 1; before the staff tilts the processing box 1 to pour out the accumulated granules in the processing box 1, by pulling the two sets of guide plates 401, the lower surfaces of the two sets of guide plates 401 are abutted against the side of the processing box 1 close to the driving mechanism 8, so that the two sets of guide mechanisms 4 guide the granules poured out of the processing box 1, thereby minimizing the mixing of the sieved granules when the subsequent staff collects the granules poured out of the processing box 1.

[0035] like Figure 1As shown, the two groups of guide plates 401 are both provided with an L-shaped limit plate 5 on one side away from the processing box 1, and the height of the lower surface of the L-shaped limit plate 5 is kept parallel to the height of the lower surface of the guide plate 401; specifically, before the staff uses the guide plate 401 to guide and transport the granules inside the processing box 1, by rotating the guide plate 401, the lower surface of the guide plate 401 is abutted against the outer surface of the side of the processing box 1 close to the driving mechanism 8, and then the height of the lower surface of the L-shaped limit plate 5 is kept parallel to the height of the lower surface of the guide plate 401, so that the L-shaped limit plate 5 is The downward movement path of the material guide plate 401 is restricted, so as to avoid the material guide plate 401 carrying a large mass during use and causing bending at the connection between the processing box 1 and the hinge 402, thereby improving the service life of the material guide mechanism 4; when the two sets of limit plates 403 inside the material guide mechanism 4 are clamped in the groove of the processing box 1, the L-shaped limit plate 5 is pulled to drive the material guide plate 401 to rotate quickly on the side of the processing box 1 close to the driving mechanism 8, thereby shortening the time and labor spent by the staff in rotating the material guide plate 401.

[0036] like Figure 1 As shown, a triangular support plate 6 is installed on one side of the processing box 1 close to the L-shaped limit plate 5; specifically, when the staff pushes the processing box 1 to rotate on the ground to pour the granules accumulated on the upper ends of the two groups of screens 702 out of the interior of the processing box 1, the processing box 1 is pushed on the ground to rotate, and the lower surface of the bottom of the triangular support plate 6 away from the processing box 1 is abutted against the ground, so that the triangular support plate 6 supports the position of the processing box 1 after rotation, so that the staff does not need to manually support the position of the processing box 1 when cleaning the granules accumulated inside the processing box 1, thereby reducing the labor consumed by subsequent staff when cleaning the granules accumulated inside the processing box 1; the position of the triangular support plate 6 is set on the side of the processing box 1 close to the material guiding mechanism 4, so that the triangular support plate 6 limits the inclination angle of the processing box 1 to the side of the material guiding mechanism 4, thereby trying to avoid the processing box 1 from tipping over and injuring the staff who are cleaning the granules inside the processing box 1 when taking out the granules accumulated inside the processing box 1, thereby improving the safety of the device during use.

[0037] like Figure 4As shown, grooves are provided on the upper surfaces of the two groups of U-shaped fixing plates 701, and baffles 9 are inserted into the grooves of the two groups of U-shaped fixing plates 701. The back of the baffle 9 abuts against the inner wall of the back of the processing box 1, and the baffle 9 is located at the front end of the card slot of the processing box 1; specifically, the baffle 9 is located at the front end of the card slot of the processing box 1, so that the baffle 9 blocks the inside of the card slot of the processing box 1, thereby preventing the granules subsequently introduced into the processing box 1 from entering the inside of the card slot of the processing box 1 and causing obstruction of personnel during the up and down movement of the screening mechanism 7 in the card slot of the processing box 1.

[0038] In summary, by pulling the driving rod 704, the two groups of U-shaped support plates are driven to pull the two groups of U-shaped fixed plates 701 to move up and down reciprocatingly inside the card slot of the processing box 1, so that the top group of screens 702 vibrate and screen the granules accumulated on the upper surface, and then the position of the screen 702 is set inside the U-shaped fixed plate 701, so that the U-shaped fixed plate 701 limits the use form of the screen 702, thereby trying to avoid the deformation of the screen 702 in the process of screening the granules, which causes the inner diameter of the sieve hole inside the screen 702 to expand or shrink; by starting the motor 801, the fixed disc 803 is driven to trigger the connecting rod 804 to pull the top rod 805 to move up and down reciprocatingly, and then the driving rod 704 is installed on the upper surface of the top rod 805, so that the driving mechanism 8 accelerates during the startup process to drive the driving rod 704 to drive the two groups of screens 702 to move up and down reciprocatingly, thereby improving the screening efficiency of the two groups of screens 702 when screening granules.

[0039] At the same time, by pushing the two groups of guide plates 401, the opposite sides of the two adjacent groups of limit plates 403 are respectively abutted against the front and rear inner walls of the grooves of the processing box 1, so that the positions of the two groups of guide plates 401 are clamped on the side of the processing box 1 close to the driving mechanism 8, and then the two groups of guide plates 401 cover the exposed parts of the two groups of grooves of the processing box 1, thereby minimizing the dust from entering the interior of the processing box 1 along the two groups of grooves of the processing box 1 during the subsequent idle storage process; by pulling the two groups of guide plates 401, the lower surfaces of the two groups of guide plates 401 are abutted against the side of the processing box 1 close to the driving mechanism 8, so that the two groups of guide mechanisms 4 guide the granules poured out of the processing box 1, thereby minimizing the mixing of the sieved granules when the subsequent staff collects the granules poured out of the processing box 1.
