Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] Example 1

[0028] like Figure 1 to Figure 5 As shown, this embodiment proposes an automated production line screening device, including a fixed frame 4 and a frame 10, the top of the fixed frame 4 is fixedly connected to the production equipment 1 by bolts, the production equipment 1 is installed with a controller 2, the fixed frame 4 is fixedly connected to the drop hopper 3 by bolts, the fixed frame 4 is installed with a motor 12, the output end of the motor 12 is fixedly connected to a coaxially arranged rotating column by a coupling, the outer circumference of the rotating column is fixedly sleeved with a third synchronous wheel 16, the fixed frame 4 is fixedly connected to four symmetrically arranged upper side plates 21 by bolts, the fixed frame 4 is fixedly connected to four symmetrically arranged lower side plates 22 by bolts, and the upper side plates 21 and the lower side plates 22 are jointly hinged. A rocker 8 is connected, and two symmetrically arranged fixed blocks 19 are welded on the fixed frame 4. The two fixed blocks 19 are internally installed with a rotating shaft 6 for common rotation. A first synchronous wheel 14 is fixedly sleeved on the outer circumference of the rotating shaft 6. Through the arrangement of structures such as the coarse screen plate 9 and the frame 10, the workpiece falls downward through the drop hopper 3 after being processed inside the production equipment 1. The rotating shaft 6 rotates through the pull rod 17 and the connecting plate 18 to drive the frame 10 to move forward and backward. At this time, the materials that fall on the coarse screen plate 9 will be retained on the surface of the coarse screen plate 9 in the process of movement if the size is larger, and the smaller ones will fall onto the fine screen plate 11 through the sieve holes inside the coarse screen plate 9, thereby achieving an efficient screening effect.

[0029] like Figure 1 to Figure 5 As shown, a movable block 7 is movably hinged on the rotating shaft 6 , a pull rod 17 is welded on the movable block 7 , a connecting plate 18 is fixedly connected to the bottom of the frame 10 by bolts, and one end of the pull rod 17 is movably hinged inside the connecting plate 18 .

[0030] like Figure 1 to Figure 5 As shown, a coarse screen plate 9 and a fine screen plate 11 are fixedly arranged inside the frame 10 , and the coarse screen plate 9 is located above the fine screen plate 11 .

[0031] like Figure 1 to Figure 5 As shown, the two fixing blocks 19 are provided with rotation grooves penetrating through the two fixing blocks 19, and the rotation shaft 6 is rotatably installed inside the rotation grooves.

[0032] like Figure 1 to Figure 5 As shown, a hinge groove is provided inside the connecting plate 18, and one end of the pull rod 17 is movably hinged inside the hinge groove.

[0033] like Figure 1 to Figure 5 As shown, a discharge hole is provided inside the production equipment 1 , and the discharge hole is communicated with the opening of the discharge hopper 3 .

[0034] In this embodiment, the production equipment 1 and the electrical start are first started by the controller 2, and the workpiece processing is completed inside the production equipment 1. The processed workpiece falls into the inside of the hopper 3 through the discharge hole opened in the production equipment 1, and then the workpiece falls on the coarse screen plate 9. The motor 12 drives the rotating column and the third synchronous wheel 16 to rotate together, and the synchronous belt 20 drives the first synchronous wheel 14 and the rotating shaft 6 to rotate together. When the rotating shaft 6 rotates, it drives the movable block 7 and the pull rod 17 movably hinged therewith to move together, and the pull rod 17 drives the frame 10 to move together through the connecting plate 18 at the bottom of the frame 10. During the movement, the frame 10 also drives the workpiece on the coarse screen plate 9 to shake. At this time, the workpieces on the coarse screen plate 9 with qualified sizes are retained on the surface of the coarse screen plate 9, and the unqualified and small ones pass through the sieve holes and fall downward to the top of the fine screen plate 11, and some of the separated processing debris fall through the sieve holes opened in the fine screen plate 11.

[0035] After the screening is completed, the falling material protection plate on the coarse screen plate 9 is opened to take out the qualified workpieces, and some unqualified workpieces on the fine screen plate 11 are discharged through the inclined plate fixedly connected to the frame 10, and the unloading and screening work is completed at this time.

[0036] Example 2

[0037] like Figure 1 to Figure 5 As shown, based on the same concept as the above-mentioned embodiment 1, this embodiment further proposes that one side of the fixed frame 4 is fixedly connected with a protective cage 5 by bolts, a rotating rod is rotatably installed inside the protective cage 5, and a cleaning blade 13 is fixedly connected to the outer circumference of the rotating rod by screws, and a second synchronous wheel 15 is fixedly sleeved on the outer circumference of the rotating rod, and a synchronous belt 20 is jointly sleeved on the first synchronous wheel 14, the second synchronous wheel 15 and the third synchronous wheel 16. Through the arrangement of structures such as the protective cage 5 and the cleaning blade 13, the cleaning blade 13 rotates, and the generated wind is blown out from the air outlet opened on the protective cage 5. At this time, some processing debris sticking to the surface of the workpiece will be blown away, thereby achieving a preliminary separation effect.

[0038] like Figure 1 to Figure 5 As shown, a rotation groove is provided inside the protection cage 5, and the cleaning blade 13 is located inside the rotation groove.

[0039] In this embodiment, in order to reduce the difficulty of subsequent cleaning work, a pre-treatment device is set when the workpiece falls, so that the debris stuck to the workpiece during the production process can be pre-separated. Specifically, a cleaning fan 13 blades are set on the outlet side of the hopper 3, and the rotating rod rotates under the action of the second synchronous wheel 15 and drives the cleaning fan 13 blades at the same time. The wind generated by the cleaning fan 13 blades will blow on the surface of the workpiece. In this process, some debris stuck to the surface of the workpiece will be blown away, thereby achieving a pre-treatment effect.
