[0002] As a key component in the plastic powder spraying production line, the plastic powder spraying line plastic powder silo is mainly used for storing and supplying the plastic powder coating required in the spraying process. It not only ensures the continuous and stable supply of the plastic powder coating for the production line, but also prevents the plastic powder from getting damp, caking or being contaminated through a closed structure, thereby protecting the quality of the plastic powder.

[0003] The inventor of this application found the following problems in the practical use process:

[0004] Currently, when replacing the plastic powder in the existing plastic powder spraying line plastic powder silo, it is generally necessary to disassemble the powder supply pipe from the plastic powder silo, empty the plastic powder inside the powder supply pipe and the spray gun pipe, and then connect the powder supply pipe to another plastic powder silo for use. The operation process is cumbersome, the labor cost is relatively high, which affects the production efficiency. Moreover, when disassembling and discharging the plastic powder in the pipe, it is easy to cause the spillage of the plastic powder, resulting in environmental pollution, and at the same time, the operator is prone to inhale the dust, thus causing potential safety hazards.

[0032] To facilitate the understanding of the present utility model, the present utility model will be described more comprehensively below with reference to the relevant drawings. The typical embodiments of the present utility model are shown in the drawings.

[0033] Embodiment 1:

[0034] As Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 shown, a powder spraying line plastic powder bin for quickly replacing plastic powder of the present utility model includes a bin mechanism 1 and a filtering mechanism 7. The bin mechanism 1 includes a bin outer shell 101. A blanking port 102 is opened at the bottom of the bin outer shell 101. A top plate 104 is arranged at the top of the bin outer shell 101. A motor 108 is arranged at the top of the top plate 104. Feeding ports 109 are arranged around the motor 108. A rotating rod 107 is arranged at the output end of the motor 108. A partition 105 is fixedly connected to the rotating rod 107. One end of the partition 105 is fixedly connected to a bin inner shell 103. A storage bin 106 is arranged inside the bin inner shell 103;

[0035] The filtering mechanism 7 includes a filtering outer shell 701. An air inlet 702 is opened on one side of the filtering outer shell 701. A filter element 703 is arranged on one side of the air inlet 702. A fine dust sensor 704 is arranged on one side of the filter element 703. An air exhaust grille 705 is arranged on one side of the fine dust sensor 704. The bin outer shell 101 protects the internal storage bin and the transmission mechanism from the influence of the external environment, ensures its stable operation, can withstand various stresses during storage and transportation, and guarantees the durability and safety of the bin. The air exhaust grille 705 is located at the outlet of the filtering mechanism 7 to ensure that the filtered clean air can be discharged smoothly.

[0036] As Figure 2 、 Figure 4 shown, a plurality of storage bins 106 are arranged. The plurality of storage bins 106 are evenly arranged at equal intervals in a circumferential array. A plurality of storage bins 106 can be pre-filled with different types or colors of plastic powder. When it is necessary to replace the plastic powder, only need to rotate the storage bin 106 to the corresponding position, and the powder replacement process can be quickly completed, improving the production efficiency. The circumferential array arrangement method enables the storage bin 106 to be optimally utilized in a limited space. Each storage bin 106 can make full use of its storage space, improving the compactness and integration of the equipment.

[0037] As Figure 2 、 Figure 4As shown in the figure, the shape of the blanking port 102 is set as a sector. The blanking port 102 is adapted to the storage bin 106. The tight adaptation between the blanking port 102 and the storage bin 106 ensures good sealing between them. When it is necessary to change the type of plastic powder, the adapted blanking port 102 and storage bin 106 can be quickly and accurately docked together. The sector-shaped blanking port 102 helps the plastic powder to flow out more smoothly under the action of gravity and rotational force.

[0038] As Figure 3 shown in the figure, a number of filter elements 703 are provided. The number of filter elements 703 is evenly arranged at equal intervals in a linear array. By setting a plurality of filter elements 703, the filtration area is significantly increased, enabling more plastic powder particles to be effectively intercepted, thereby improving the overall filtration efficiency and filtration quality. The evenly arranged linear array helps to evenly distribute the air flow entering the filtration mechanism 7, avoiding problems such as uneven filtration or uneven wear of the filter elements 703 caused by excessive or too small local air flow.

[0039] As Figure 1 shown in the figure, the bottom shapes of the bin outer shell 101 and the bin inner shell 103 are both set as conical. Brushes are provided on both sides of the bottom of the partition 105, and the brushes are used to sweep the plastic powder at the bottom of the storage bin 106. The conical bottom helps the plastic powder to slide down naturally under the action of gravity, reducing the accumulation and retention of the plastic powder at the bottom of the storage bin 106, thereby promoting the smooth flow of the plastic powder. The brushes at the bottom of the partition 105 can sweep the plastic powder at the bottom of the storage bin 106 when the storage bin 106 rotates, helping to push the residual plastic powder towards the blanking port 102.

[0040] As Figure 3 shown in the figure, the model of the dust sensor 704 is S7 Smart Dust. The dust sensor 704 is used to detect the dust concentration inside the filtration mechanism 7. The S7 Smart Dust dust sensor 704 adopts the principle of optical opposed beams and can accurately measure the number and concentration data of dust particles in the air. The dust sensor 704 can display the dust concentration inside the filtration mechanism 7 in real time, enabling the operator to grasp the operating status and filtration effect of the equipment at any time.

[0041] Embodiment 2:

[0042] As Figure 1 shown in the figure, a first blanking pipe 2 is provided at the bottom of the blanking port 102. A three-way valve 3 is provided at the bottom of the first blanking pipe 2. The three-way valve 3 allows switching between three channels, which enables the plastic powder bin to flexibly control the flow of the plastic powder. When changing the plastic powder, by switching the three-way valve 3, the mixing of different plastic powders can be avoided. The first blanking pipe 2, as the connection channel between the blanking port 102 and the subsequent equipment, ensures the stability and sealing of the connection, preventing the leakage of the plastic powder.

[0043] As shown Figure 1 As shown, a second blanking pipe 4 is provided at the bottom of the three-way valve 3, and an air extraction pipe 5 is provided on one side of the three-way valve 3. An air pump 6 is provided at one end of the air extraction pipe 5. The second blanking pipe 4 serves as a channel for the plastic powder to flow from the storage bin 106 to the powder spraying line, ensuring that the plastic powder can flow smoothly and avoiding blockage and retention phenomena. The air pump 6 provides stable air flow power for the air extraction pipe 5, ensuring the smooth progress of the plastic powder cleaning work.

[0044] In implementation, first, different plastic powders are added into the storage bin 106 through the feeding port 109. When the plastic powder needs to be replaced, the inner shell 103 of the bin is rotated by the rotating rod 107 to move the current storage bin 106 away from the blanking port 102. At the same time, the three-way valve 3 is switched and the plastic powder inside the powder supply pipe and the spray gun pipe is pumped to the filtering mechanism 7 through the air pump 6. Then, another storage bin 106 is aligned with the blanking port 102 and the three-way valve 3 is switched again to complete the replacement of the plastic powder. The dust sensor 704 will detect the dust content of the gas discharged from the filtering mechanism 7. When the content exceeds the threshold, an external control console is alerted through an electrical signal to remind the operator to repair the equipment and replace the filter element 703.

[0045] The advantages in practical applications of this technical solution include but are not limited to the following points:

[0046] 1. The bin mechanism and the filtering mechanism enable the rapid replacement of the plastic powder, reduce the powder replacement time, and improve the production efficiency;

[0047] 2. The three-way valve and the air pump make the flow direction of the plastic powder more flexible and controllable, ensuring that the plastic powder flows out of the correct storage bin during the replacement of the plastic powder and avoiding the mixing of different plastic powders.

[0048] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
