A bearing sleeve is provided on one side of the inner cavity of the mounting frame 11, and the bearing sleeve is connected to the fixed shaft 13. A PLC controller 38 is provided on the outer side of the mounting frame 16. By providing the PLC controller 38, various devices requiring electricity can be controlled to improve the accuracy of the device. The two sets of air outlet holes 28 are both inclined. By setting the air outlet holes 28 to an inclined shape, the plaster can be split after cutting. A connecting plate 29 is provided on one side of the mounting frame 16, and a fixed frame 31 is provided on one side of the connecting plate 29. A dryer 4 is provided at the bottom of the fixed frame 31. Through the cooperation of the hair dryer 27, the conveyor belt 26, the air outlet holes 28 and the dryer 4, When the operator has finished cutting the plaster, the plaster can be moved to the bottom of the hair dryer 27 through the action of the conveyor belt 26. At this time, the operator can start the hair dryer 27, and the hair dryer 27 can blow the wind through the inclined air outlet 28, so as to improve the effect of plaster separation. When completed, the conveyor belt 26 can convey the plaster to the bottom of the dryer 4. At this time, the plaster can be dried by the dryer 4.

The temperature monitor 39 can monitor and control the temperature of the dryer 4, improve the drying effect of the plaster, and facilitate the operator to use. A conveyor belt 26 is provided on the surface of the conveying roller 25. By setting the conveyor belt 26, the plaster can be conveyed. The dryer 4 is arranged directly above the conveyor belt 26. Nuts are provided on the surfaces of the threaded rod 34 and the bolt 32. A hole is opened on one side of the mounting frame 11, and the fixed shaft 13 is inserted into the inside of the hole. A fixed platform is provided on one side of the mounting frame 11, and the servo motor 12 is provided on the top of the fixed platform. By setting the fixed platform, the stability of the servo motor 12 can be improved.
[0041] Specifically, the working process or working principle of the traditional Chinese medicine plaster cutting device is as follows: when in use, when traditional Chinese medicine specifically cuts the plaster, the usual device directly places the completed plaster on the conveyor belt 26, and then needs to cut it to a suitable length, and then use it after completion, but in the cutting process, it is necessary to use scissors for cutting multiple times, and scissors are inconvenient to cut, the efficiency is low, and the cutting length cannot be adjusted according to needs, which is inconvenient for the operator to use. Therefore, the technical solution can solve the above problems. When the operator needs to cut the completed traditional Chinese medicine plaster, the operator can first start the reduction motor 21 to drive the mounting rod 22, and the mounting rod 22 can drive the two sets of sprockets 24 to rotate through the action of the chain 23. When the sprocket 24 rotates, the conveying roller 25 can be driven to rotate, and the conveying roller 25 can drive the conveyor belt 26 to rotate. When completed, the operator can place the finished Chinese medicine plaster on the top of the conveyor belt 26. While placing it, the operator can start the servo motor 12 to drive the fixed shaft 13, and the fixed shaft 13 can drive the cam 14. When the cam 14 rotates to the mounting plate 15, the mounting plate 15 is resisted. When it resists, the mounting plate 15 can move downward. When the mounting plate 15 moves, the mounting frame 16 can move downward synchronously. When moving, it can drive the first scissors 17 and the second scissors 18 to cut the plaster horizontally and vertically synchronously, and the spring 37 can be compressed. When the plaster cutting is completed After that, the spring 37 rebounds to restore the mounting plate 15 to its original position, and the plaster can be conveyed to the next procedure by the conveyor belt 26, so that the plaster can be cut synchronously horizontally and vertically, without multiple cutting, thereby improving the cutting efficiency of the plaster and facilitating the use of the operator. When the operator cuts plasters of different lengths as needed, the operator can take out the threaded rod 34 from the inside of the threaded hole 33. After taking out, the operator can take out the second scissors 18. After taking out, the operator can adjust the second scissors 18. When adjusting, the operator can place the second scissors 18 at the required threaded hole 33. After placing, the operator can insert the threaded rod 34 into the inside of the threaded hole 33, so that the plaster can be cut horizontally and vertically synchronously. The position of the second scissors 18 is adjusted to facilitate the operator to cut plasters of different lengths. When the first scissors 17 and the second scissors 18 are used for a long time and the cutting effect cannot meet the operator's needs, the operator can take out the threaded rod 34 and the nut on the bolt 32, and remove the first scissors 17 and the second scissors 18, and replace or maintain them for the convenience of the operator. When the operator has finished cutting the plaster, the plaster can be moved to the bottom of the hair dryer 27 through the action of the conveyor belt 26. At this time, the operator can start the hair dryer 27, and the hair dryer 27 can blow air through the inclined air outlet 28, thereby improving the effect of plaster separation. When completed, the conveyor belt 26 can transport the plaster to the bottom of the dryer 4.At this time, the plaster can be dried by the dryer 4, which can remove excess moisture, ensure the stability and shelf life of the plaster, and improve the overall quality of the plaster. After all the processing is completed, the plaster can be processed later, which is convenient for the operator to use, and all the processes are completed.
