DETAILED DESCRIPTION

[0031] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0032] Example 1:

[0033] Please refer to Figures 1 to 5, an efficient drug production raw material screening device, comprising: a collecting box 1, with brackets 2 fixed on both sides of the collecting box 1, a screening plate 3 rotatably connected between the two brackets 2, support plates 4 fixed on the tops of the two brackets 2, a discharge box 5 fixed between the two support plates 4, the bottom end of the discharge box 5 is connected to a discharge hopper 6, a rotating shaft 7 is rotatably connected inside the discharge hopper 6, four guide plates 8 are symmetrically fixed to the outer wall of the rotating shaft 7, a top plate 9 is provided on the top of the discharge box 5 which can be raised and lowered, and a plurality of dredging rods 10 located in the discharge box 5 are fixed to the bottom end of the top plate 9;

[0034] The material discharging box 5 is used for storing the raw materials to be screened. The raw materials are transported to the material discharging box 5, and then the raw materials fall onto the screening plate 3 along the material discharging hopper 6, so that the raw materials can be swung and screened by the screening plate 3, and when the raw materials are discharged through the material discharging hopper 6, the rotation of the rotating shaft 7 drives the rotation of the guide plate 8. There are four material guide plates 8, so that during the rotation of the four material guide plates 8, the raw materials can fall into the space between two adjacent material guide plates 8, and then be guided out during the rotation process. Since the space is fixed, the raw materials can be quantitatively discharged to avoid accumulation caused by excessive discharge of raw materials, which is convenient for the screening of raw materials. Moreover, under the lifting movement of the top plate 9, the dredging rod 10 is driven to move up and down, so that the dredging rod 10 moves up and down in the material discharging box 5. In this way, under the movement of the dredging rod 10, the raw materials in the material discharging box 5 can be dredged to avoid bridging blockage of the raw materials, which is convenient for the discharge of raw materials.

[0035] In a further embodiment, Figure 4 As shown, the drive motor 11 is fixedly arranged on one side of one of the brackets 2. The output shaft of the drive motor 11 is provided with a swing assembly 12 for driving the movement of the screening plate 3. The swing assembly 12 includes a cam 121. The cam 121 is fixedly arranged on the output shaft of the drive motor 11. One end of the cam 121 is hinged with a first connecting rod 122. One end of the first connecting rod 122 is hinged with a second connecting rod 123. One end of the second connecting rod 123 is fixedly connected to one end of the rotating shaft of the screening plate 3.

[0036] Under the movement of the driving motor 11, the cam 121 is driven to rotate. Since the end of the cam 121 is hinged to the first connecting rod 122, the cam 121 drives the reciprocating motion of the first connecting rod 122, and the first connecting rod 122 can drive the reciprocating swing of the second connecting rod 123. The second connecting rod 123 drives the reciprocating swing of the screening plate 3. When the screening plate 3 swings, the raw materials can be swung and screened. Moreover, during the swinging process of the screening plate 3, the raw materials continue to flow on the screening plate 3, which makes it convenient to turn over and spread the raw materials, thereby facilitating the screening of the raw materials.

[0037] In a further embodiment, Figure 3As shown, the linkage assembly 13 is arranged between the drive motor 11 and the rotating shaft 7, and is used to drive the rotation of the rotating shaft 7. The linkage assembly 13 includes a first synchronous wheel 131 and a second synchronous wheel 132. The first synchronous wheel 131 is sleeved on the outer wall of the output shaft of the drive motor 11, and the second synchronous wheel 132 is sleeved on the outer wall of the rotating shaft 7. The first synchronous wheel 131 and the second synchronous wheel 132 are connected by a synchronous belt 133.

[0038] When the drive motor 11 is in motion, it also drives the first synchronous wheel 131 to rotate, and the first synchronous wheel 131 drives the second synchronous wheel 132 to rotate through the synchronous belt 133, and the second synchronous wheel 132 drives the rotation of the rotating shaft 7, and the rotating shaft 7 drives the rotation of the guide plate 8. In this way, the raw materials can be quantitatively discharged during the continuous rotation and transposition of the guide plate 8, avoiding accumulation of raw materials due to excessive discharge, and facilitating the screening of raw materials.

[0039] In a further embodiment, Figure 5 As shown, the reciprocating assembly 14 is arranged between the rotating shaft 7 and the top plate 9, and is used to drive the reciprocating motion of the top plate 9. The reciprocating assembly 14 includes a first gear 141, which is sleeved on the outer wall of the rotating shaft 7. One side of one support plate 4 is rotatably connected to a second gear 142 that meshes with the first gear 141, and one side of the second gear 142 is hinged with a pull rod 143, and one end of the pull rod 143 is hinged with a vertical plate 144 fixed to the top plate 9.

[0040] When the rotating shaft 7 rotates, it also drives the rotation of the first gear 141, and the first gear 141 drives the meshing rotation of the second gear 142. Since the pull rod 143 is hinged to the side position of the second gear 142, the second gear 142 can drive the eccentric rotation of the hinge point of the pull rod 143, so that the pull rod 143 can reciprocate, and the pull rod 143 can drive the vertical plate 144 to move back and forth, and the vertical plate 144 drives the top plate 9 to move back and forth, and the top plate 9 drives the dredging rod 10 to move back and forth. In this way, under the movement of the dredging rod 10, the raw materials in the discharge box 5 can be dredged to avoid accumulation and blockage of the raw materials, which facilitates the discharge and screening of the raw materials.

[0041] In a further embodiment, Figure 5 As shown, it also includes two support assemblies 15, and the support assembly 15 includes a first support rod 151 and a second support rod 152. The first support rod 151 is fixedly set at the top end of the support plate 4, and the second support rod 152 is fixedly set at the bottom end of the top plate 9. The first support rod 151 and the second support rod 152 are interlaced and connected.

[0042] When the top plate 9 moves back and forth up and down, it drives the first support rod 151 and the second support rod 152 to interweave and move. In this way, with the interweaving cooperation of the first support rod 151 and the second support rod 152, it is convenient to perform auxiliary support and limit on the top plate 9, so that the top plate 9 can move stably and avoid tilting and shaking during the movement of the top plate 9.

[0043] Example 2:

[0044] Please refer to Figures 6 and 7 The top of the screening plate 3 is slidably provided with a slide plate 16, and the slide plate 16 is connected to the screening plate 3 through a guide assembly 17. A first push plate 18 is fixed to the bottom end of the slide plate 16, and a second push plate 19 is inserted and connected to the bottom end of the first push plate 18. A plurality of comb teeth 20 are fixed to the bottom end of the second push plate 19, and a groove 21 for the second push plate 19 to insert is provided at the bottom end of the first push plate 18. An elastic assembly 22 for driving the second push plate 19 to move is provided in the groove 21.

[0045] When the screening plate 3 swings back and forth, under the action of gravity of the slide plate 16, the slide plate 16 swings back and forth following the screening plate 3, the slide plate 16 drives the first push plate 18 to swing back and forth, the first push plate 18 drives the second push plate 19 to swing back and forth, the second push plate 19 drives the comb teeth 20 to swing back and forth, and under the elastic cooperation of the elastic component 22, the comb teeth 20 are driven to move elastically, so that the comb teeth 20 contact with the raw materials on the screening plate 3. In this way, with the cooperation of the comb teeth 20, the raw materials on the screening plate 3 can be combed, which facilitates the rapid screening of the raw materials.

[0046] In a further embodiment, Figure 7 As shown, the guide assembly 17 includes two first sliders 171, which are respectively fixed on both sides of the bottom end of the slide 16. First slide grooves 172 for sliding the first sliders 171 are provided on both sides of the top of the screening plate 3. Slide rails 173 are fixed on both sides of the first slider 171, and slideways 174 adapted to the slide rails 173 are fixed on both sides of the inner wall of the first slide groove 172.

[0047] When the slide 16 swings back and forth, it drives the first slider 171 to slide in the first slide groove 172. In this way, with the cooperation of the first slider 171 and the first slide groove 172, it is convenient to assist in supporting and limiting the slide 16. In addition, with the cooperation of the slide rail 173 and the slide way 174, the slide rail 173 and the slide way 174 adopt a drawer steel ball slide rail structure, which makes it convenient to convert sliding friction into rolling friction, thereby reducing the friction force when the slide 16 slides and facilitating the sliding of the slide 16.

[0048] In a further embodiment, Figure 6As shown, the elastic component 22 includes two connecting rods 221, and the two connecting rods 221 are hingedly arranged at the top of the second push plate 19. The top of the two connecting rods 221 is hinged with a second slider 222. The top of the inner wall of the groove 21 is provided with a second sliding groove 223 for the second slider 222 to slide, and both sides of the inner wall of the second sliding groove 223 are elastically connected to the second slider 222 through a spring 224.

[0049] When the slide plate 16 swings back and forth, under the elastic action of the spring 224, the second slider 222 is driven to move elastically, and the second slider 222 drives the elastic movement of the connecting rod 221, and the connecting rod 221 drives the elastic movement of the second push plate 19. The second push plate 19 drives the elastic movement of the comb teeth 20, so that the comb teeth 20 are in full contact with the raw materials on the screening plate 3, which makes it convenient to comb the raw materials through the comb teeth 20, thereby facilitating the screening of the raw materials.

[0050] In a further embodiment, Figure 4 As shown, third sliders 23 are fixed on both sides of the second push plate 19 , third sliding grooves 24 are opened on both sides of the inner wall of the groove 21 , and two third sliders 23 are slidably set in the two third sliding grooves 24 respectively.

[0051] When the second push plate 19 moves, it drives the third slider 23 to slide in the third slide groove 24. In this way, with the cooperation of the third slider 23 and the third slide groove 24, the second push plate 19 can be auxiliary supported and limited, which facilitates the stable movement of the second push plate 19.

[0052] In a further embodiment, Figure 1 As shown, blanking plates 25 are fixed on both sides of the screening plate 3 , and storage boxes 26 corresponding to the blanking plates 25 are fixed on both sides of the collecting box 1 .

[0053] When the screening plate 3 swings to screen the raw materials, the screened debris and the like fall through the screening plate 3 into the collection box 1, while the qualified raw materials remain on the screening plate 3. Then, during the swinging process of the screening plate 3, the raw materials are discharged into the storage box 26 along the discharge plate 25, so that the raw materials can be screened, classified and collected.

[0054] The working principle of the high-efficiency drug production raw material screening device provided by the present invention is as follows:

[0055] Under the movement of the driving motor 11, the cam 121 is driven to rotate. Since the end of the cam 121 is hinged to the first connecting rod 122, the cam 121 drives the reciprocating motion of the first connecting rod 122, and the first connecting rod 122 can drive the reciprocating swing of the second connecting rod 123, and the second connecting rod 123 drives the reciprocating swing of the screening plate 3. When the driving motor 11 is in motion, the first synchronous wheel 131 is driven to rotate at the same time, and the first synchronous wheel 131 drives the second synchronous wheel 131 through the synchronous belt 133. 32 rotates, the second synchronous wheel 132 drives the rotation of the rotating shaft 7, and the rotating shaft 7 drives the rotation of the guide plate 8. When the rotating shaft 7 rotates, it also drives the rotation of the first gear 141, and the first gear 141 drives the meshing rotation of the second gear 142. Since the pull rod 143 is hinged at the side position of the second gear 142, the second gear 142 can drive the eccentric rotation of the hinge point of the pull rod 143, so that the pull rod 143 reciprocates, and the pull rod 143 can drive the reciprocating up and down of the vertical plate 144. The dredging rod 10 is driven by the lifting and lowering movement of the top plate 9, and the dredging rod 10 is driven by the lifting and lowering movement of the top plate 9, so that the whole device is in the starting state, and then the raw materials are transported to the discharge box 5, and the raw materials fall onto the screening plate 3 along the discharge hopper 6, so that the screening plate 3 can swing screen the raw materials, and when the raw materials pass through the discharge hopper 6, the four guide plates 8 rotate, and the raw materials can fall into the space between the two adjacent guide plates 8, and then be guided out during the rotation process. Since the space is fixed, the raw materials can be quantitatively discharged, avoiding accumulation caused by excessive discharge of raw materials, and facilitating the screening of raw materials. In addition, the lifting and lowering movement of the top plate 9 drives the dredging rod 10 to move up and down, so that the dredging rod 10 moves up and down in the discharge box 5, so that the raw materials in the discharge box 5 can be dredged under the movement of the dredging rod 10, avoiding bridging blockage of the raw materials, facilitating the discharge of the raw materials, thereby facilitating the screening of the raw materials and improving the screening efficiency of the raw materials.
