However, the screw shaft continuously pushes the phenolic resin powder from one side to the other side, and the powder continuously passes through multiple discharge pipes. Inevitably, the actual discharge amount of the discharge pipe closer to the feeding port is more, resulting in easy deviation of the actual filling amount of each station. Therefore, an automatic weighing and sealing packaging machine for phenolic resin powder is urgently needed to solve the above problems. Content of the Utility Model

[0031] The following will clearly and completely describe the technical solutions in the present utility model in conjunction with the drawings in the present utility model.

[0032] Embodiment 1:

[0033] Refer to the drawings in the specification Figures 1-3, the present utility model provides an automatic weighing and sealing packaging machine for phenolic resin powder. The feeding mechanism 100 consists of a feeding bin 110 with a screw shaft inside and several discharging pipes 111 at the bottom end. The feeding bin 110 is used for material storage and transportation. The screw shaft rotates inside the feeding bin 110 and pushes the material from the feeding bin 110 to the discharging pipes 111 in a spiral propulsion manner. The several discharging pipes 111 are evenly distributed at the bottom end of the feeding bin 110 to ensure that the material can be discharged dispersedly, preparing for the subsequent weighing work;

[0034] The weighing mechanism 200 takes the temporary storage pipe 210 connected to the bottom end of the discharging pipe 111 through a corrugated hose as the core. Electrically controlled flaps 211 are connected to both the upper and lower openings of the temporary storage pipe 210. The electrically controlled flaps 211 can control their states through electrical signals. When horizontal, they can block the passage of materials, and when vertical, they allow the passage of materials, enabling the temporary storage pipe 210 to precisely control the entry and exit of materials and achieve the temporary storage and discharge of materials;

[0035] A connecting frame 212 is connected to the outside of the temporary storage pipe 210. The connecting frame 212 serves to connect the temporary storage pipe 210 and the hanging scale 213. There are holes in the connecting frame 212. The bearing part of the hanging scale 213 is hook-shaped and placed in the holes of the connecting frame 212 to achieve a stable connection between the two. The hanging scale 213 is electrically connected to the electrically controlled flap 211 and can monitor the weight change of the temporary storage pipe 210 in real time. The number of hanging scales 213 is at least two and is distributed in a ring along the midpoint of the temporary storage pipe 210 to more evenly measure the weight of the temporary storage pipe 210 and improve the accuracy of weighing. The electrically controlled flap 211 is placed on the inner wall of the temporary storage pipe 210. When the electrically controlled flap 211 is in a horizontal state, it is flush with the upper and lower openings of the temporary storage pipe 210.

[0036] Feeding process: When using this packaging machine, the material first enters the inside of the feeding bin 110 from the feeding port of the feeding bin 110. Subsequently, the screw shaft in the feeding bin 110 starts to rotate, pushing the material to continuously pass through multiple discharging pipes 111 to achieve the preliminary transportation of the material.

[0037] Weighing and discharging process: During the material transportation process, the upper and lower electrically controlled flaps 211 of the temporary storage pipe 210 always maintain a state of one horizontal and one vertical. When the upper electrically controlled flap 211 is vertical, the material can continuously enter the temporary storage pipe 210. Since the lower electrically controlled flap 211 is in a horizontal state, it blocks the falling of the material, causing the material to accumulate in the temporary storage pipe 210, thereby increasing the weight of the temporary storage pipe 210. When the hanging scale 213 detects that the weight of the temporary storage pipe 210 reaches the rated weight, the upper electrically controlled flap 211 flips to a horizontal state to block the material from continuing to enter the temporary storage pipe 210. At the same time, the lower electrically controlled flap 211 flips to a vertical state, causing the material to be discharged from the bottom end of the temporary storage pipe 210 to complete a single discharging operation.

[0038] Embodiment Two:

[0039] Referring to the accompanying drawings of the specification Figure 4 , the difference between this embodiment and the above-mentioned embodiment is that the feeding bin 110 is designed as a detachable structure, which is connected by bolts between the bin body and the bin cover, ensuring both the stability of the overall structure of the feeding bin 110 and facilitating disassembly when needed, providing convenience for the repair and maintenance of internal components;

[0040] The feeding port of the feeding bin 110 is arranged on the bin cover, and the feeding port is located at the starting point of the auger pushing the material in the bin body of the feeding bin 110, enabling the material to directly fall into the position where the auger shaft starts to work, facilitating the auger shaft to quickly push the material into the discharge pipe 111, improving the efficiency of material transportation, and reducing the accumulation and residue of the material in the bin;

[0041] A rubber sheet for sealing is provided at the joint between the bin body and the bin cover of the feeding bin 110. The rubber sheet has good elasticity and sealing performance, which can effectively prevent material leakage, avoid material loss and pollution to the working environment, and at the same time prevent foreign impurities from entering the inside of the feeding bin 110, ensuring the purity of the material and the normal operation of the equipment;

[0042] The bottom end of the bin body of the feeding bin 110 is inclined at an angle less than ten degrees towards the farthest discharge pipe 111. The design of the small inclination angle helps the material to flow more smoothly towards the discharge pipe 111 under the action of gravity, reducing the residue of the material at the bottom of the bin body, further improving the efficiency of material transportation, and ensuring that the material can be discharged from the discharge pipe 111 as completely as possible.

[0043] When repairing and maintaining the automatic weighing and sealing packaging machine for phenolic resin powder, the detachable structure of the feeding bin 110 plays an important role. The operator can easily separate the bin body and the bin cover by removing the bolts between the bin body and the bin cover of the feeding bin 110. After separation, the auger shaft inside the bin body is completely exposed, and the maintenance personnel can conveniently conduct a comprehensive inspection of the auger shaft.

In this specification, the schematic representations of the above terms do not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials, or characteristics described can be combined in a suitable manner in any one or more embodiments or examples.
