Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0052] like Figures 1 to 4 As shown, this embodiment provides an automatic feeding device for the production of methyl benzylsulfonamide, comprising: a base plate 1, a delivery pipe 2, a feeding mechanism, a quantitative mechanism and a limiting mechanism. The delivery pipe 2 is fixedly connected to the base plate 1. Through the cooperation between the base plate 1, the delivery pipe 2, the feeding mechanism, the quantitative mechanism and the limiting mechanism, the raw materials are automatically quantitatively proportioned and automatically fed, thereby improving the efficiency of quantitative discharge and feeding of the raw materials.

[0053] like Figure 1 、 Figure 2 and Figure 4As shown, the feeding mechanism is arranged on the base plate 1 for conveying raw materials, and the feeding mechanism includes: a conveying shaft 3, a toothed belt 4, a tooth rack 5, a driving assembly and an adjusting assembly. A slide rod 25 is fixedly connected to the base plate 1, and two sliders 26 are fixedly connected to the other toothed belt 4. Both sliders 26 are provided with sliding holes. The slide rod 25 is slidably arranged in the two sliding holes, and the conveying shaft 3 is slidably arranged in the conveying pipe 2. There are two toothed belts 4, one of which is fixedly connected to the conveying shaft 3, and the other toothed belt 4 is slidably arranged on the base plate 1. The tooth rack 5 is arranged between the two toothed belts 4, and the tooth rack 5 is engaged with the two toothed belts 4. The driving assembly is arranged on the base plate 1 for driving the tooth rack 5 to swing, and the adjusting assembly is arranged on the base plate 1 for adjusting the position of the other toothed belt 4. The driving assembly includes: a driving frame 6, a connecting rod 7 and a first motor 8. The driving frame 6 is rotatably connected to the base plate 1, and the connecting rod 7 is rotatably connected between the driving frame 6 and the tooth rack 5. The first motor 8 is arranged on the base plate 1 On the top, the output end of the first motor 8 is fixedly connected to the driving frame 6, and the adjusting component includes: an adjusting block 9, a moving screw 10 and a second motor 11. The adjusting block 9 is fixedly connected to another toothed belt 4. A screw hole is opened on the adjusting block 9, and the moving screw 10 is threadedly connected to the screw hole. The second motor 11 is arranged on the base plate 1, and the output end of the second motor 11 is fixedly connected to the moving screw 10. Specifically, the driving frame 6 is driven to rotate by the first motor 8. When the driving frame 6 rotates, the connecting rod 7 is driven to swing, and then the toothed belt 4 is driven to swing between the two toothed belts 4, thereby driving the toothed belt 4 fixed on the conveying shaft 3 and the conveying shaft 3 to move in the conveying pipe 2, thereby pushing out the raw materials falling into the conveying pipe 2 for feeding. When different amounts of material need to be conveyed, the moving screw 10 is driven to rotate by the second motor 11. When the moving screw 10 rotates, it drives the adjusting block 9 and another toothed belt 4 to move, thereby adjusting the transmission angle of the tooth frame 5, thereby adjusting the raw material conveying amount.

[0054] like Figures 1 to 3As shown, the quantitative mechanism is arranged on the conveying pipe 2 for quantitatively measuring the raw materials. The quantitative mechanism includes: a lower hopper 12, a discharge hopper 13, a weight scale 14, a support frame 15 and an opening and closing component. The lower hopper 12 is connected to the conveying pipe 2, and the discharge hopper 13 is slidably arranged on the conveying pipe 2. The discharge hopper 13 is located above the lower hopper 12. The weight scale 14 is arranged on the conveying pipe 2, and the support frame 15 is fixedly connected to the discharge hopper 13. The bottom end of the support frame 15 is in contact with the weight scale 14. The opening and closing component is arranged on the conveying pipe 2 for controlling the discharge of the discharge hopper 13. The opening and closing component includes: an opening and closing plate 16 and a first electric cylinder 17. The conveying pipe 2 is fixedly connected with a stabilizing frame 23. The stabilizing frame 2 3 is rotatably connected to a support wheel 24, which contacts the opening and closing plate 16. The opening and closing plate 16 is provided on the conveying pipe 2 and contacts the discharge hopper 13. The first electric cylinder 17 is provided on the conveying pipe 2, and the output end of the first electric cylinder 17 is fixedly connected to the opening and closing plate 16. Specifically, the raw material is poured into the discharge hopper 13. At this time, the opening and closing plate 16 closes the discharge hopper 13. As the raw material in the discharge hopper 13 continues to increase, the support frame 15 presses on the weight scale 14 to obtain the weight of the raw material. After the specified weight of the raw material is added to the discharge hopper 13, the first electric cylinder 17 drives the opening and closing plate 16 to move, opens the discharge hopper 13, and allows the raw material to fall into the conveying pipe 2 through the lower hopper 12 for conveying.

[0055] like Figure 2~Figure 3 As shown, a limiting mechanism is provided on the conveying pipe 2 for limiting the position of the raw materials. The limiting mechanism includes: a rotating rod 18, a baffle 19 and a transmission assembly. The rotating rod 18 is rotatably connected to the conveying pipe 2, and the baffle 19 is fixedly connected to the rotating rod 18.

The third motor 22 is provided on the conveying pipe 2, and the output end of the third motor 22 is fixedly connected to the other transmission wheel 20. Specifically, the conveying pipe 2 is blocked by the baffle 19. When the conveying pipe 2 is filled with raw materials, the transmission wheel 20 is driven to rotate by the third motor 22, and the transmission belt 21 drives the two transmission wheels 20 to rotate synchronously, thereby driving the rotating rod 18 and the baffle 19 to rotate, thereby opening the conveying pipe 2, so that the raw materials can be fed smoothly.

[0056] In this embodiment, when it is necessary to quantitatively dose and feed the raw materials, the raw materials are poured into the discharge hopper 13. At this time, the opening and closing plate 16 closes the discharge hopper 13. As the raw materials in the discharge hopper 13 continue to increase, the support frame 15 presses on the weight scale 14 to obtain the weight of the raw materials. After the specified weight of the raw materials is added to the discharge hopper 13, the first electric cylinder 17 drives the opening and closing plate 16 to move, opens the discharge hopper 13, and allows the raw materials to fall into the conveying pipe 2 through the lower hopper 12 for conveying. The driving frame 6 is driven to rotate by the first motor 8. When the driving frame 6 rotates, it drives the connecting rod 7 to swing, thereby driving the toothed belt 4 to swing between the two toothed belts 4, thereby driving the toothed belt 4 fixed on the conveying shaft 3 and the conveying shaft 3 moves in the conveying pipe 2, thereby pushing out the raw materials that have fallen into the conveying pipe 2 for feeding. When different amounts of materials need to be conveyed, the second motor 11 drives the moving screw 10 to rotate. When the moving screw 10 rotates, it drives the adjustment block 9 and another toothed belt 4 to move, thereby adjusting the transmission angle of the rack 5, thereby adjusting the raw material feeding amount. The conveying pipe 2 is blocked by the baffle 19. When the conveying pipe 2 is filled with raw materials, the third motor 22 drives the transmission wheel 20 to rotate, and the transmission belt 21 drives the two transmission wheels 20 to rotate synchronously, thereby driving the rotation rod 18 and the baffle 19 to rotate, thereby opening the conveying pipe 2, so that the raw materials can be fed smoothly.

[0057] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
