[0037] By setting up the conveying mechanism, it is realized that the double-axis motor is used to drive the conveyor belt to convey the container, and the rotation of the fan blades is used to limit the amount of the container flowing backward and flowing to the lower material device driven by the conveyor belt.

[0038] A specific application of this embodiment is as follows: by setting a clamping mechanism, after the container is conveyed to the bottom of the device by the conveyor belt and the height is adjusted, the first motor 4 drives the idler wheel 5 to rotate and drive the two gears 7 to rotate, and the two gears 7 respectively drive the two bidirectional threaded rods 6 to rotate. Since the threads at both ends of the bidirectional threaded rod 6 are in opposite directions, when the bidirectional threaded rod 6 rotates, it drives the two threaded sliders 8 to move horizontally inward along the threads. When the rubber extrusion block 11 on the threaded slider 8 contacts the bottle mouth of the container, the rubber extrusion block 11 slides inside the extrusion groove 9 to squeeze the spring 10. At this time, the spring 10 is in a compressed state. When the container is filled with raw materials, the first motor 4 rotates to drive the idler wheel 5 to drive the threaded slider 8 to move horizontally outward according to the above process to release the bottle mouth of the container. At this time, the spring 10 rebounds and ejects the rubber extrusion block 11. A PLC controller 12 is set to control the smooth operation of the device, so that the first motor drives the extrusion block to fix and clamp the bottle mouth of the container inward, and the elasticity of the spring and the plasticity of the rubber on the rubber extrusion block are used to greatly protect the bottle mouth of the container from deformation under the clamping and fixing of the device, thereby reducing the defective products caused by the deformation of the bottle mouth.

[0039] By setting the flow limiting mechanism, when the container reaches the specified position, the two cylinders 16 drive the gas telescopic rod 17 to slide the two lifting blocks 3 downward, wherein the two slide grooves 14 of the lifting block 3 slide downward along the two slide rails 15, drive the feeding pipe 19 and the two connecting blocks 13 to move downward, and insert the feeding pipe 19 into the container. At this time, the material pump 25 extracts the raw materials in the raw material warehouse 24 through the feeding pipe 26 and transports the raw materials to the feeding pipe 19. At this time, the second motor 21 in the fixed block 20 drives the first rotating shaft 22 to rotate and drive the two flow limiting blocks 23 to rotate. The flow limiting blocks 23 are used to block the feeding of the feeding pipe 26. The base 2 and the support rod 27 are set to support and stabilize the feeding device, wherein the PLC controller 12 controls the driving speed and rotation direction of the second motor 21, and realizes the use of the motor to rotate the flow limiting block to control the feeding and stopping of the raw materials. When the amount or speed of the feeding is too high, the area of ​​the feeding port of the feeding pipe can be controlled by the flow limiting block to control the amount and speed of the raw materials, thereby achieving the effect of automatic controllable feeding.

[0040] By setting up a conveying mechanism, the container is conveyed by a conveyor belt 40, and a double-axis motor 28 drives a first bevel gear 29. Since the first bevel gear 29 is meshed with the second bevel gear 31, the first bevel gear 29 rotates to drive the second bevel gear 31 to rotate, and the second bevel gear 31 drives the second rotating shaft 30 and the pulley 32 to rotate. The pulley 32 rotates to drive the third rotating shaft 34 to rotate through the belt 36 and the belt groove 35. The third rotating shaft 34 drives a plurality of fan blades 37 to rotate around the third rotating shaft 34. The rotation of the fan blades 37 limits the inflow of the container. The double-axis motor 28 drives the transmission shaft 39 to rotate and drives the conveyor belt 40 to perform the conveying work in the conveyor housing 38, thereby realizing the use of a double-axis motor to drive the conveyor belt to convey the container, and the rotation of the fan blades is used to limit the amount of the container flowing backward and flowing to the feeding device driven by the conveyor belt.
