[0018] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.
[0019] The first embodiment of this application is as follows:
[0020] Please see Figures 1 to 3 ,in, Figure 1 This is a schematic diagram of the overall structure of the screening device according to the first embodiment of this utility model. Figure 2 This is a cross-sectional view of the screening device according to the first embodiment of this utility model. Figure 3 This is a positional diagram of the engaging groove 109 in the first embodiment of this utility model.
[0021] This utility model provides a screening device, including a housing 101, a separation mechanism, a fixing plate 102, a receiving assembly, a shock-absorbing base 110, a shock-absorbing spring 111, and a buffer spring 112. The receiving assembly includes a guide plate 103, a receiving box 104, a conveyor belt 105, and auxiliary components. The auxiliary components include a baffle 106, a guide block 107, and a locking block 108. The receiving box 104 has a locking groove 109. The aforementioned solution solves the problem that when a full collection box needs to be removed, the machine must be stopped and workers must be waited for to pick it up, which delays efficiency. It is understood that the aforementioned solution can also be used to assist in solving screening problems.
[0022] In this specific embodiment, the separation mechanism is located inside the housing 101, and the fixing plate 102 is located outside the housing 101. The separation mechanism adopts the separation mechanism disclosed in announcement number CN215354613U for tablet sieving. This is prior art and will not be described in detail here.
[0023] The discharge plate 103 is fixedly connected to the housing 101 and located inside the housing 101. The receiving box 104 is located below the discharge plate 103, and the conveyor belt 105 is located at the bottom of the receiving box 104. The auxiliary component is connected to the receiving box 104. The discharge plate 103 is fixed inside the housing 101 to guide the defective tablets that fall after screening and discharge them into the housing 101. The receiving box 104 is located below the housing 101 and receives and stores the defective tablets discharged by the discharge plate 103. The conveyor belt 105 is a belt conveyor, and the receiving box 104 is placed on the conveyor belt 105 and transported by it.
[0024] Secondly, there are two baffles 106, located on opposite sides of the conveyor belt 105. The guide block 107 is fixedly connected to the receiving box 104 and slidably connected to the baffles 106. The baffles 106, positioned on opposite sides of the conveyor belt 105, limit the conveying of the receiving box 104. The guide block 107 guides the receiving box 104 along the baffles 106, ensuring it is positioned more precisely below the output plate 103, which is beneficial for receiving defective tablets.
[0025] Meanwhile, the engaging block 108 is fixedly connected to the receiving box 104 and located on one side of the receiving box 104. The receiving box 104 has an engaging groove 109, which is positioned opposite the engaging block 108 and located on the other side of the receiving box 104. The engaging block 108 is positioned in front of the receiving box 104, and the engaging groove 109 engages with the engaging block 108 and is positioned behind the receiving box 104. When multiple receiving boxes 104 are placed on the conveyor belt 105, they can be connected continuously, thus continuously entering below the output plate 103 for more accurate collection of defective tablets.
[0026] In addition, there are multiple shock-absorbing springs 111, each connected to the housing 101 and located at the bottom of the housing 101. Each shock-absorbing spring 111 has a shock-absorbing base 110 fixedly connected to its end furthest from the housing 101. A vibration motor is also installed on the outer wall of the housing 101. When started, the motor drives the housing 101 to vibrate, assisting the screening inside the housing 101 and improving the screening effect. The elasticity of the shock-absorbing springs 111 assists the vibration of the housing 101. The shock-absorbing base 110 is used to fix the housing 101 to the ground or other carrier, providing support.
[0027] Finally, multiple buffer springs 112 are respectively located between the fixed plate 102 and the housing 101. The buffer springs 112 play a buffering role when the housing 101 vibrates and assist the vibration of the housing 101, which is beneficial to improving the screening effect.
[0028] Using a screening device according to this embodiment, tablets are placed in the separation mechanism inside the housing 101. The separation mechanism is used to screen defective tablets. The screened tablets fall into the output plate 103 and are discharged into the receiving box 104 through the output plate 103. When the receiving box 104 is full, the conveyor belt 105 is started to output the full receiving box 104 to the bottom of the housing 101. At the same time, the empty receiving box 104, which is engaged with the full receiving box 104, is placed below the output plate 103 to continue receiving tablets. There is no need to stop and wait, which effectively improves screening efficiency.
[0029] The above-disclosed embodiments are merely one or more preferred embodiments of this application and should not be construed as limiting the scope of this application. Those skilled in the art can understand that all or part of the processes for implementing the above embodiments and equivalent changes made in accordance with the claims of this application still fall within the scope of this application.
