[0026] Embodiment 1:

[0027] See Figures 1-4, A device for controllable-speed feeding in the processing of sodium methoxide, which includes a feeding box 1. A sealing plate 11 is arranged at the top of the feeding box 1, and a feeding port 12 is arranged on the sealing plate 11. The bottom of the feeding box 1 is a discharging port. A sealing cover is installed on the feeding port 12. A horizontal roller conveyor 3 is arranged at the top inside the feeding box 1. One end of the roller conveyor 3 is the feeding end, and the other end is the discharging end. The feeding end of the roller conveyor 3 is located directly below the feeding port 12. A cutting mechanism 2 for breaking open the sodium methoxide packaging bag is arranged above the roller conveyor 3. A discharging mechanism 4 for cleaning the remaining materials in the sodium methoxide packaging bag is arranged at the discharging end of the roller conveyor 3. By putting multiple bags of sodium methoxide packaging bags into the roller conveyor 3 inside the feeding box 1 through the feeding port 12, during the transportation by the roller conveyor 3, the cutting mechanism 2 cuts the packaged sodium methoxide packaging bag into two halves from the middle. Then the roller conveyor 3 continues to transport and unloads it onto the discharging mechanism 4. The discharging mechanism 4 pours out the two half-packages of sodium methoxide from the packaging bag. The poured sodium methoxide deposits at the bottom of the feeding box 1 under the action of gravity, realizing rapid unpacking by the cooperation of the roller conveyor 3 and the cutting mechanism 2, and at the same time, rapid feeding by the discharging mechanism 4, so that the feeding speed in the sodium methoxide processing and feeding process is maintained within a controllable range. The entire unpacking and feeding process is carried out in a sealed environment to prevent dust pollution.

[0028] In this embodiment, refer to Figure 1 , 2 , The cutting mechanism 2 includes a cutting saw blade 21, a cutting shaft 22, a mounting seat 23, and a fourth motor 24. The mounting seat 23 is fixed to the bottom of the sealing plate 11. The cutting shaft 22 is rotatably arranged on the mounting seat 23. The cutting saw blade 21 is coaxially and fixedly arranged on the cutting shaft 22. A fourth motor 24 for driving the cutting shaft 22 to rotate is arranged on the mounting seat 23. By driving the cutting shaft 22 to rotate through the fourth motor 24, the cutting saw blade 21 is driven to rotate to vertically cut the sodium methoxide packaging bag, cutting the sodium methoxide packaging bag into two halves from the middle, which is convenient for feeding.

[0029] In this embodiment, refer to Figure 1 , 3, 4. The roller conveyor 3 includes rollers 31, first bearing seats 32, sprockets 33, chains 34, and a second motor 35. A plurality of rollers 31 are horizontally arranged at intervals in sequence on the inner top of the feeding box 1. Specifically, the cutting saw blade 21 should be installed between two adjacent rollers 31, and the lower part of the cutting saw blade 21 extends into the groove between two adjacent rollers 31, so that the installation height of the lower cutting edge of the cutting saw blade 21 is lower than the conveying height of the packaging bag, realizing the complete separation of the two halves of the sodium methoxide packaging bag and increasing the efficiency of pouring. The central axis of one end of each roller 31 vertically passes through the side wall of the feeding box 1 and extends outside the feeding box 1 and is horizontally rotatably supported by the first bearing seat 32 provided on the outer side wall of the feeding box 1. A sprocket 33 is coaxially arranged at the outer extending end of the central axis of each roller 31, and the sprockets 33 are connected and driven by a chain 34. The outer extending end of the central axis of one of the rollers 31 is coaxially and fixedly connected to the output shaft of the second motor 35 provided on the side wall of the feeding box 1. The second motor 35 is supported and fixed by a horizontal steel plate welded and fixed on the outer side wall of the feeding box 1. By driving the central axis of one of the rollers 31 to rotate through the second motor 35, the sprocket 33 installed on it is driven to rotate, and the chain 34 drives other sprockets 33 to rotate through the chain 34, so that all the sprockets 33 rotate synchronously and in the same direction to convey the bagged sodium methoxide, enabling the stable conveying and feeding of sodium methoxide.

[0030] In this embodiment, refer to Figure 1 , 3 , the discharging mechanism 4 includes a third motor 41, a sieve cylinder 42, a support shaft 43, a support rod 44, and a second bearing seat 45. The sieve cylinder 42 is horizontally arranged at the discharging end of the roller conveyor 3. One end of the sieve cylinder 42 is the feeding end, and the other end is the discharging end. A spiral-shaped convex platform is arranged on the inner wall of the sieve cylinder 42, so that the packaging bag can be conveyed spirally along the direction of the discharging end. The feeding end of the sieve cylinder 42 is connected to the discharging end of the roller conveyor 3 for receiving the broken packaging bag. A support shaft 43 is coaxially arranged in the sieve cylinder 42, and the support shaft 43 is connected to the inner wall of the sieve cylinder 42 through a support rod 44. One end of the support shaft 43 is rotatably connected to the second bearing seat 45 provided on the side wall of the feeding box 1. Specifically, the support shaft 43 passes through the side wall of the feeding box 1 and extends outside the feeding box 1 and is inserted into the bearing hole of the second bearing seat 45, forming a single-end support structure of the support shaft 43 and being rotatable. The third motor 41 is arranged on the outer side wall of the feeding box 1, and the output shaft of the third motor 41 is coaxially and fixedly connected to the outer extending end of the support shaft 43. The third motor 41 is supported and fixed by a horizontal steel plate welded and fixed on the outer side wall of the feeding box 1. By driving the sieve cylinder 42 to rotate through the third motor 41, the two halves of the packaging bag entering the sieve cylinder 42 are tumbled and conveyed during the rotation of the sieve cylinder 42, and the materials in the packaging bag can be completely poured out and fall through the sieve cylinder 42 to the bottom of the feeding box 1.

[0031] In this embodiment, refer to Figure 1, the lower end of the feeding box 1 is a converging hopper 10. A plurality of pneumatic vibrators 5 are arranged on the side wall of the hopper 10. Through the pneumatic vibrators 5, the materials adsorbed on the inner wall of the hopper 10 can be quickly cleaned, preventing the materials from sticking to the wall and affecting the discharging.

[0032] In this embodiment, referring to Figure 1 , an observation window 13 and a dust removal port 14 are arranged on the sealing plate 11. Through the observation window 13, the dumping condition of the packaging bags in the sieve cylinder 42 and the accumulated materials in the hopper 10 can be observed, so as to reasonably control the dumping speed of sodium methoxide. The dust removal port 14 is connected to a dust collector through a dust removal pipe 15, and the dust generated in the feeding box 1 can be absorbed and reused. A packaging bag outlet 16 is arranged on the side wall of the feeding box 1 and is connected to the discharging end of the roller conveyor 3. A sealing door is arranged at the packaging bag outlet 16. When it is observed through the observation window 13 that there are too many plastic packaging bags accumulated in the sieve cylinder 42, the feeding work can be stopped, the sealing door of the packaging bag outlet 16 can be opened to take out the empty packaging bags, preventing too much accumulation from affecting the dumping.

[0033] As can be seen from the above technical solutions, during use, first, the dust collector is controlled to be opened by the controller, and then multiple bags of sodium methoxide packaging bags are placed on the roller conveyor 3 in the feeding box 1 through the feeding port 12. The roller conveyor 3 is started to convey each sodium methoxide packaging bag to the lower part of the cutting mechanism 2, and the packaged sodium methoxide packaging bag is cut into two halves from the middle. Then the roller conveyor 3 continues to convey the two halves of the sodium methoxide packaging bags to the discharging mechanism 4, and the two halves of the sodium methoxide are poured out of the packaging bags through the discharging mechanism 4. The poured sodium methoxide is deposited at the bottom of the feeding box 1 under the action of gravity, realizing rapid unpacking through the cooperation of the roller conveyor 3 and the cutting mechanism 2, and at the same time rapid discharging through the discharging mechanism 4. When it is observed through the observation window 13 that there are too many plastic packaging bags accumulated in the sieve cylinder 42, the feeding work is stopped, the sealing door of the packaging bag outlet 16 is opened to take out the empty packaging bags, and then the feeding work continues.
