Specific implementation mode

[0021] The following will further elaborate on this application in conjunction with the attached Figures 1-4 diagram.

[0022] The embodiment of this application discloses a blanking and conveying mechanism for a packaging machine. Referring to Figure 2 and Figure 3 , for a blanking and conveying mechanism for a packaging machine, on both sides of the interior of the blanking bin 1, there are fixedly connected support plates 11. On one side of the lower surface of each support plate 11, there are fixedly connected several first springs 18. The lower surface of the support plate 11 is elastically slidably connected to several support rods 19 through several first springs 18, and several support rods 19 extend to the outside of the support plate 11. The upper surface of the support plate 11 is connected to a filter plate 10 through several support rods 19 for lifting. On one side corresponding to the support plate 11 inside the blanking bin 1, there is a rotatably connected connecting rod 16, and the connecting rod 16 extends to the outside of the blanking bin 1. On one side of the outer wall of the connecting rod 16, there are fixedly connected several cams 17;

[0023] By adopting the above technical solution, through the connection between the connecting rod 16 and several cams 17, the connecting rod 16 drives several cams 17 to rotate, and the outer wall of the cam 17 is in close contact with the bottom of the filter plate 10. As the connecting rod 16 drives several cams 17 to rotate, when the protruding part of the cam 17 rotates to the bottom of the filter plate 10, the protruding part of the cam 17 pushes the filter plate 10 to rise. At the same time, several support rods 19 are connected to the filter plate 10, and the support rods 19 and the bottom of the filter plate 10 are connected through the first springs 18, so that the rising of the filter plate 10 drives the support rods 19 to move upward, and simultaneously compresses several first springs 18. Further, when the connecting rod 16 drives the cam 17 to rotate, the elastic potential energy generated by the compression of the first spring 18 drives the filter plate 10 to move downward. Then, through the continuous rotation of the connecting rod 16 driving the cam 17, the filter plate 10 vibrates up and down as a whole, and then screens the materials on the surface of the filter plate 10, dropping the unqualified materials from the surface of the filter plate 10, achieving the effect of facilitating the screening of materials.

[0024] Reference Figure 1 、 Figure 2 and Figure 3 , the inner side of the lower silo 1 corresponds to the filter plate 10 and is rotatably connected to a threaded rod 13, and the threaded rod 13 extends to the outside of the lower silo 1, and the outer wall side of the connecting rod 16 is fixedly connected to the driving wheel 7, and the outer wall side of the threaded rod 13 is fixedly connected to the driven wheel 5, and the driven wheel 5 and the driving wheel 7 are connected by a conveyor belt 6. The side surface of the lower silo 1 is fixedly connected to the motor 4, and the driving end of the motor 4 is fixedly connected to one side of the connecting rod 16;

[0025] By adopting the above technical solution, the threaded rod 13 is connected to the driven wheel 5, the connecting rod 16 is connected to the driving wheel 7, and the driven wheel 5 and the driving wheel 7 are connected by the conveyor belt 6, so that the connecting rod 16 and the threaded rod 13 can rotate simultaneously, and the motor 4 is connected to the connecting rod 16, so that the motor 4 drives the connecting rod 16 to rotate, thereby driving the threaded rod 13 to rotate simultaneously, achieving the effect of facilitating the simultaneous rotation of the threaded rod 13 and the connecting rod 16.

[0026] Reference Figure 2 、 Figure 3 and Figure 4 , a connecting plate 14 is threadedly connected to one side of the outer wall of the threaded rod 13, a sliding groove 20 is opened on the inner side of the connecting plate 14, a second spring 21 is fixedly connected to the inner side of the sliding groove 20, and a connecting block 22 is elastically slidably connected to the inner side of the sliding groove 20 through the second spring 21. The interior of the lower hopper 1 is elastically lifted and lowered by the second spring 21 and the connecting block 22. A sliding opening 23 is opened on the inner side of the pushing plate 15 corresponding to the connecting block 22;

[0027] By adopting the above technical solution, the connecting block 22 inside the connecting plate 14 is fixedly connected to the sliding port 23 opened inside the push plate 15, so that the push plate 15 can be lifted and lowered along the outer wall of the connecting plate 14, and then when the filter plate 10 is driven to move upward, the push plate 15 is pushed to move upward along the connecting plate 14, and is connected to the connecting block 22 through the second spring 21. The size of the connecting block 22 matches the size of the chute 20, so that the push plate 15 moves upward and drives the connecting block 22 to move upward, and at the same time, the second spring 21 inside the chute 20 is pressed. The spring 21 is compressed. When the filter plate 10 moves downward, the elastic potential energy generated by the compression of the second spring 21 pushes the connecting block 22 downward, and drives the push plate 15 downward, so that the bottom of the push plate 15 is in close contact with the surface of the filter plate 10. It is connected to the connecting plate 14 through the threaded rod 13, so that the threaded rod 13 rotates and drives the connecting plate 14 to move along the surface of the filter plate 10, pushing the qualified material on the surface of the filter plate 10 toward the discharge port, so as to achieve the effect of ensuring that the bottom of the push plate 15 and the surface of the filter plate 10 can continue to be in close contact.

[0028] Reference Figure 1 and Figure 2 , on one side of the upper surface of the filter plate 10, a discharge port 12 is provided. On one side of the inner part of the blanking bin 1, a guide plate 8 is fixedly connected. On the upper surface of the guide plate 8, a blanking port 9 is provided corresponding to one side of the discharge port 12. On one side of the side surface of the blanking bin 1, a waste box 3 is fixedly connected. On one side of the lower surface of the blanking bin 1, a support table 2 is fixedly connected;

[0029] By adopting the above technical solution, the discharge port 12 on the surface of the filter plate 10 corresponds to the blanking port 9 on the surface of the guide plate 8, so that the pusher plate 15 pushes the qualified material into the discharge port 12, and the material falls into the discharge pipe along the inner wall of the blanking bin 1 through the blanking port 9. Due to the correspondence between the guide plate 8 and the waste box 3, the unqualified material falls onto the surface of the guide plate 8 through the filter holes on the filter plate 10, and the unqualified material slides down along the surface of the guide plate 8 into the waste box 3 for collection. Since a pull plate is provided inside the waste box 3, the staff can pull the pull plate to take out the collected unqualified material, achieving the effect of facilitating the separation of qualified materials and unqualified materials.

[0030] The implementation principle of the feeding and conveying mechanism for a packaging machine in an embodiment of the present application is as follows: First, a conveyor belt 6 is used to connect the driven wheel 5 and the driving wheel 7, enabling the connecting rod 16 and the threaded rod 13 to rotate simultaneously. The motor 4 drives the connecting rod 16 to rotate, causing the connecting rod 16 to drive a number of cams 17 to rotate. The outer wall of the cam 17 is in close contact with the bottom of the filter plate 10. Subsequently, the connecting rod 16 drives a number of cams 17 to rotate. When the protruding part of the cam 17 rotates to the bottom of the filter plate 10, the protruding part of the cam 17 pushes the filter plate 10 upward. At the same time, a number of support rods 19 are connected to the filter plate 10, and the support rods 19 and the bottom of the filter plate 10 are connected by the first spring 18, causing the upward movement of the filter plate 10 to drive the support rods 19 to move upward and compress a number of first springs 18 simultaneously. Further, when the connecting rod 16 drives the cam 17 to rotate, the elastic potential energy generated by the compression of the first spring 18 drives the filter plate 10 to move downward. Subsequently, the connecting rod 16 drives the cam 17 to continuously rotate, causing the entire filter plate 10 to vibrate up and down, thereby screening the materials on the surface of the filter plate 10. At the same time, a connecting block 22 inside the connecting plate 14 is fixedly connected to a sliding opening 23 formed inside the push plate 15, enabling the push plate 15 to move up and down along the outer wall of the connecting plate 14. Subsequently, when driving the filter plate 10 to move upward, the push plate 15 is pushed to move upward along the connecting plate 14. The connecting block 22 is connected to the second spring 21, and the size of the connecting block 22 fits the size of the sliding groove 20, causing the upward movement of the push plate 15 to drive the connecting block 22 to move upward and compress the second spring 21 inside the sliding groove 20 simultaneously. When the filter plate 10 moves downward, the elastic potential energy generated by the compression of the second spring 21 pushes the connecting block 22 to move downward and drives the push plate 15 to move downward, causing the bottom of the push plate 15 to be in close contact with the surface of the filter plate 10. The threaded rod 13 is connected to the connecting plate 14, causing the rotation of the threaded rod 13 to drive the connecting plate 14 to move along the surface of the filter plate 10, pushing the qualified materials on the surface of the filter plate 10 towards the discharge port. As a result, the qualified materials fall into the discharge pipe along the inner wall of the feeding bin 1 through the feeding port 9, and the unqualified materials fall onto the surface of the guide plate 8 through the filter holes on the filter plate 10.
