Detailed Implementation

[0018] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, which constitute a part of this application and are used together with the embodiments of the present invention to illustrate the principles of the present invention, but are not intended to limit the scope of the present invention.

[0019] like Figure 1-4As shown, an embodiment of this utility model provides a feeding system, including several pouring devices 1, storage tanks 2 corresponding to each pouring device 1, and screw conveying devices 3 corresponding to each storage tank 2. The pouring devices 1 are used to guide the material to be poured in. The top of the storage tank 2 is provided with a storage tank inlet corresponding to the pouring device 1, and the bottom of the storage tank 2 is provided with a storage tank outlet. The screw conveying device 3 includes a conveying pipe 31, a driving device 32, a screw 33, and a spiral blade 34. The conveying pipe 31 is arranged in a horizontal direction. One end of the conveying pipe 31 is connected to the outlet of the storage tank, and the other end is provided with a discharge port. One end of the screw 33 extends into the conveying pipe 31. The spiral blade 34 is helically fixed to the portion of the screw 33 located inside the conveying pipe 31. The driving device 32 is fixed to the conveying pipe 31 and connected to the screw 33, and is used to drive the screw 33 to rotate relative to the conveying pipe 31.

[0020] In use, the material is poured into the pouring device 1, and the material is guided by the pouring device 1 to the storage tank 2 for buffering. The material in the storage tank 2 falls onto the screw conveyor 3. The rotation speed of the screw 33 can be adjusted by adjusting the output of the drive device 32, thereby adjusting the discharge rate of the screw conveyor 3, so that different materials have different discharge rates to form a set mixing ratio.

[0021] Specifically, the material pouring device 1 includes a support frame 11, a negative pressure component 12, and a connecting pipe 13. The support frame 11 has a fixing surface that can be fixed to the storage tank 2. The negative pressure component 12 is detachably fixed to the support frame 11. A channel that allows material to pass through is formed in the middle of the negative pressure component 12. A negative pressure can be formed in the channel. One end of the connecting pipe 13 is detachably connected to the feed inlet of the processing device, and the other end is connected to the channel.

[0022] Furthermore, the support frame 11 includes a horizontal frame 111 and a vertical support leg 112. One end of the vertical support leg 112 is fixed to the bottom of the horizontal frame 111, and the other end face forms the fixing surface that is fixed to the storage tank 2. A hollow hole is opened on the horizontal frame 111, and the channel of the negative pressure component 12 matches the hollow hole.

[0023] Specifically, the negative pressure assembly 12 includes a ring 121 and a vacuum pump. The ring 121 is fixed to the horizontal frame 111, and its inner diameter forms the channel. The suction end of the vacuum pump is connected to the ring 121. When the vacuum pump operates, it draws gas from the ring 121, creating a negative pressure on the inner diameter surface of the ring 121 to absorb dust generated during the pouring of materials.

[0024] Furthermore, the ring body 121 includes an annular chamber 1211 without a top cover, an annular top cover 1212, and filter cotton 1213. The annular top cover 1212 is detachably fixed to the upper part of the annular chamber 1211. The filter cotton 1213 fills the space between the annular chamber 1211 and the annular top cover 1212. Several through holes 1211a are formed on the inner annular surface of the annular chamber 1211. When the air pump is working, it draws gas from the annular body 121, creating a negative pressure at the through holes 1211a. This negative pressure absorbs dust generated during the pouring of materials, drawing the dust into the annular chamber 1211, where it is absorbed by the filter cotton 1213. When the filter cotton 1213 has absorbed a large amount of material, the annular top cover 1212 can be opened to replace the filter cotton 1213.

[0025] Specifically, the connecting pipe 13 is made of a flexible material, and the material falling on the inner wall of the connecting pipe 13 can play a stabilizing and buffering role.

[0026] Furthermore, the connecting tube 13 is made of a flexible, transparent material. Workers can visually observe the material falling through the connecting tube 13; if material remains on the inner wall of the connecting tube 13, workers can push the connecting tube 13 to shake off the material.

[0027] In some feasible embodiments, a material hoisting assembly 14 is also included, which is straddling the support frame 11 and is used to suspend and move the material package. In use, the material hoisting assembly 14 can move and suspend the material package above the negative pressure assembly 12, eliminating the need for workers to hold the material package and pour it out, thus reducing the labor intensity of workers.

[0028] Specifically, the material hoisting assembly 14 includes a suspension frame 141, a movable component 142, a lifting component 143, and a hook 144. The suspension frame 141 spans the support frame 11. The movable component 142 is mounted on the suspension frame 141 and has a translational end that can move in the horizontal direction. The lifting component 143 is fixed to the translational end and has a lifting end that can rise and fall in the vertical direction. The hook 144 is fixed on the lifting end.

[0029] In use, the material bag is hung on the hook 144. The moving part 142 drives the lifting part 143 and the material bag to move above the negative pressure component 12. The lifting part 143 lowers the material bag to a suitable height. The worker cuts a suitable-sized opening at the bottom of the material bag corresponding to the position in the negative pressure component 2. The material falls into the channel at a suitable speed.

[0030] It should be noted that the opening should not be too large to avoid excessive material overflow, spilling onto the outside of the negative pressure component 12 or getting too close to the inner ring surface of the annular chamber 1211, where it will be directly adsorbed; the opening should also not be too small, which would result in the material feeding speed being too slow or the material getting stuck at the opening.

[0031] Furthermore, the moving component 142 includes a sliding rail 1421 and a slider 1422. The sliding rail 1421 is fixed to the suspension frame 141 in the horizontal direction. The slider 1422 is slidably connected to the sliding rail 1421 and can slide along the sliding rail 1421 and stop at any position of its sliding stroke. The lifting component 143 is fixed to the slider 1422.

[0032] Furthermore, the lifting component 143 includes a hydraulic motor, a drum, and a steel rope. The hydraulic motor is fixed to the moving component 142, the drum is fixed to the output end of the hydraulic motor, one end of the steel rope is wound on the drum, and the other end is fixed to the hook 144.

[0033] Specifically, the storage tank 2 serves as a buffer and transfer point for materials.

[0034] Specifically, the feeding system also includes a control component and a powder flow meter. The powder flow meter is located at the discharge port of the conveying pipe 31 and is used to detect the discharge speed of the powder in the conveying pipe 31. The control component is electrically connected to the powder flow meter and the drive device 32. The control component can adjust the working state of the drive device 32 according to the detection result of the powder flow meter.

[0035] It should be noted that the control component relies on the program within it to implement the corresponding functions, but the program within the control component is a conventional feedback adjustment program in the art, and this application does not involve any improvement to the program.
