When the putty screening is completed, the closing cover 11 will drive the putty powder bag to move downward through the lifting frame 31, thereby facilitating the staff to take out the putty powder bag.

[0040] refer to Figure 11As shown, a powder vibrating screen machine for putty powder production is shown. The bottom of one side of the vibrating screen cabin 101 is connected with a shielding cloth 4. The shielding cloth 4 is used to prevent powder from spilling out of the outer surface outlet of the vibrating screen cabin 101. The bottom of the shielding cloth 4 is connected with a funnel 41. The outer surface of the funnel 41 is fixedly connected with a support plate 42. The right end of the support plate 42 is fixedly connected to the outer surface of the shell 1. The support plate 42 is used to fix the funnel 41.

The lower surface of the rotating frame 45 is rotatably connected to the upper surface of the filter screen 102, and the bottom of the rotating frame 45 is used to rotate on the upper surface of the filter screen 102, thereby increasing the mutual movement between the putty powder and the filter screen 102, making the putty powder more fully contact with the filter screen to improve the screening efficiency, and also preventing the putty powder from sticking to the upper surface of the filter screen 102, keeping the filter screen 102 unobstructed.

[0041] The complete working principle and steps of the above embodiment are as follows:

[0042] refer to Figures 1 to 5 As shown, when the vibrating screen machine is in the initial state, the closing cover 11 is in the extended state, the servo motor 15 is in the closed state, the right side of the closing cover 11 is threadedly connected to the outer surface of the top of the first threaded rod 14, and the right side of the rack 13 has not yet engaged with the outer surface of the gear 19;

[0043] When using the device to screen putty powder, the staff first places the whole bag of putty powder on the upper surface of the front side of the support frame 12 and starts the servo motor 15. At this time, the output end of the servo motor 15 drives the first threaded rod 14 to rotate at the same time. When the first threaded rod 14 rotates on the right side of the outer surface of the vibration screen cabin 101, it drives the closing cover 11 to move downward, and the left end of the closing cover 11 slides downward on the outer surface of the support rod 16. When the closing cover 11 slides downward, it drives the rack 13 to slide at the same time. When the rack 13 slides downward, it meshes with the outer surface of the gear 19 and prompts the gear 19 to rotate counterclockwise. When the needle rotates, the gear 19 rotates counterclockwise, which drives the rotating shaft 17 to rotate at the same time. When the rotating shaft 17 rotates counterclockwise, it drives the cutting blade 18 to rotate at the same time. When the cutting blade 18 rotates counterclockwise, it can cut the bottom of the putty powder packaging bag, so that the putty powder can be poured into the interior of the vibration screen cabin 101, reducing the time of manual unpacking and pouring. When the putty powder packaging bag is cut, the closing cover 11 can automatically drop to form a closed space, effectively preventing dust from flying and overflowing when the putty powder is poured, avoiding the risk of dust inhalation by the staff, and protecting the health of the staff.

[0044] When the putty powder screening is completed, the servo motor 15 is started, so that the output end of the servo motor 15 drives the first threaded rod 14 to rotate in the opposite direction. When the first threaded rod 14 rotates in the opposite direction, it can drive the closing cover 11 to move upward, so that the closing cover 11 is separated from the covering of the top of the vibration screen cabin 101. When the closing cover 11 moves upward, it will drive the rack 13 to move at the same time. When the rack 13 moves upward, it will drive the gear 19 to rotate clockwise. When the gear 19 rotates clockwise, it will drive the cutting blade 18 to rotate at the same time through the rotating shaft 17, causing the cutting blade 18 to return to its initial state.

[0045] refer to Figures 6 to 8 As shown, when the vibrating screen machine is in the initial state, the limiting plate 2 is in the expanded state, the torsion spring 22 is in the naturally relaxed state, and the sides of the bottoms of the sliding rods 23 that are close to each other are pressed against the outer surface of the top of the guide rod 21;

[0046] As the closing cover 11 moves downward, the sliding rod 23 will be driven to move at the same time. When the sliding rod 23 moves downward, the side of the bottom of the sliding rod 23 that is close to each other can squeeze the outer surface of the outer surface of the guide rod 21, causing the guide rod 21 to rotate toward the side that is close to each other. When the guide rod 21 rotates, it can drive the limiting plate 2 to swing at the same time. The swinging of the limiting plate 2 toward the side that is close to each other will prompt the torsion spring 22 to rotate to the stored force state, and the limiting plate 2 can also limit the putty powder packaging bag when it swings, so that the cutting blade 18 can cut the packaging bag more stably, and after cutting, it can also prevent the packaging bag from slipping into the inside of the vibration screen cabin 101 and affecting the screening effect and service life of the filter screen 102.

[0047] As the closing cover 11 moves upward and opens, the closing cover 11 will drive the sliding rod 23 to move at the same time. When the sliding rod 23 moves upward, it will disengage from the outer surface of the guide rod 21. At this time, the torsion spring 22 in the stored force state will drive the limiting plate 2 to reset and swing, so that the side of the limiting plate 2 that is close to each other will disengage from the outer surface of the putty powder packaging bag, so that the staff can take out the putty powder bag more quickly.

[0048] refer to Figure 9 and Figure 10 As shown, when the vibrating screen machine is in the initial state, the spring 3 is in a compressed state, the lifting frame 31 is slidably connected to the front side of the support frame 12, and the traction rope 34 is in a taut state;

[0049] As the staff puts the putty powder packaging bag onto the upper surface of the lifting frame 31, the closing cover 11 will drive the first pulley 32 to move downward, and the downward movement of the first pulley 32 will drive the traction rope 34 to move at the same time, so that the traction rope 34 moves to a relaxed state. As the weight of the putty powder on the upper surface of the lifting frame 31 is reduced, the spring 3 in the compressed state will drive the lifting frame 31 to gradually move upward. When the lifting frame 31 moves upward, the traction rope 34 will gradually return to a straight state. When the lifting frame 31 moves upward, it will also drive the putty powder packaging bag to move at the same time, which can keep the putty powder bag away from dust, thereby reducing dust adhesion to the putty powder bag and reducing dust flying when the staff takes out the putty powder bag.

[0050] As the putty powder screening is completed, the closing cover 11 will drive the first pulley 32 to move upward. When the first pulley 32 moves upward, it will drive the traction rope 34 to move at the same time. When the traction rope 34 moves upward on the outer surface of the second pulley 33, the front end of the traction rope 34 will drive the lifting frame 31 to gradually move downward. As the lifting frame 31 moves downward, it will drive the putty powder packaging bag to move at the same time, thereby making it convenient for the staff to take out the putty powder bag.

[0051] refer to Figure 11As shown, when the screening device completes screening of the putty powder, the screened putty powder can be transported from the bottom of the left side of the vibration screen cabin 101 to the inside of the shielding cloth 4, and the putty powder inside the shielding cloth 4 can accurately flow out from the inside of the funnel 41, thereby preventing the putty powder from leaking after screening and reducing the loss of materials. When the dual-axis motor 103 drives the vibration screen cabin 101 to move up and down, the vibration screen cabin 101 will drive the filter screen 102 to move at the same time. Since the lower surface of the rotating frame 45 is rotated and clamped on the filter screen 102 When the upper surface 125 moves, it will drive the rotating frame 45 to move at the same time. At this time, the inner side of the rotating frame 45 will fit against the outer surface of the top of the second threaded rod 44, so that the rotating frame 45 can rotate simultaneously when moving up and down, and the bottom of the rotating frame 45 fits against the upper surface of the filter screen 102. When rotating, it can increase the mutual movement between the putty powder and the filter screen 102, so that the putty powder can contact the filter screen more fully, thereby improving the screening efficiency, and preventing the putty powder from sticking to the upper surface of the filter screen 102, keeping the filter screen 102 unobstructed.

Therefore, the scope of the present disclosure should not be limited to the above-described embodiments, but should be determined not only by the appended claims but also by the equivalents of the appended claims.
