[0028] As shown in Figure 1 and Figure 2 , an automatic dust removal machine comprises a feeding assembly 1, a dust removal assembly 2 and a collecting assembly 3. The feeding assembly 1 comprises a fixed part 11 and a moving part 12, the moving part 12 is rotatably connected to the fixed part 11, the dust removal assembly 2 is transversely arranged above the moving part 12, and the dust removal part is fixedly arranged on the fixed part 11. The gift box 100 is placed on the moving part 12, the gift box 100 passes through the dust removal assembly 2 with the moving part 12, and the dust removal assembly 2 cleans the surface of the gift box 100. The collecting assembly 3 is connected to the dust removal assembly 2, the collecting assembly 3 generates a circulating airflow flowing through the dust removal assembly 2, the airflow carrying dust flows into the collecting assembly 3, and the collecting assembly 3 filters the dust to achieve the dust removal effect on the surface of the gift box 100. The gift box 100 after dust removal leaves the dust removal assembly 2 with the moving part 12 and enters the next process. The feeding assembly 1, the dust removal assembly 2 and the collecting assembly 3 are integrated in the same process, the dust removal of the gift box 100 can be completed during the moving process, the material transfer between traditional processes is avoided, the production efficiency is significantly improved, and the risk of dust reattachment of the gift box 100 during the transfer process is reduced.
[0029] Specifically, the feeding assembly 1 adopts a conveying belt, that is, the fixed part 11 is a support of the conveying belt, used to support and fix the overall structure of the conveying belt, and the moving part 12 is a conveying belt part, that is, a continuous movement part used to carry and move the gift box 100. More specifically, the conveying belt is horizontally placed, and the conveying belt is driven by a motor and a rotating shaft.
[0030] The bottom of the dust removal assembly 2 is concave to form a channel 4 through which the gift box 100 passes, and the length direction of the channel 4 is the same as the moving direction of the gift box 100, that is, the channel 4 is located above the moving part 12. The dust removal assembly 2 is internally provided with a dust removal chamber 21 which is in communication with the channel 4.
[0031] As shown in Figure 3 , the channel 4 is fixedly provided with an electrostatic precipitator 5 and a direct current ion wind rod 6, the direct current ion wind rod 6 is internally provided with an electrode, and a strong electric field is formed around the electrode after being powered on, so that the molecules in the air are ionized to generate a large number of positive and negative ions. The positive and negative ions generated by ionization are blown to the surface of the gift box 100 by the airflow, and meet the dust particles with static electricity. The charges on the ions and the dust particles neutralize each other, and after the neutralization of the electrostatic adsorption force of the dust, the dust particles lose the electrostatic adsorption ability, preventing the dust from being difficult to remove due to electrostatic adsorption, and then being blown away from the surface of the gift box 100 by the airflow, achieving the dust removal effect on the surface of the gift box 100.
[0032] After the electrostatic precipitator 5 is connected to a high-voltage power supply, a strong electric field is generated on the surface of the rod body, so that the surrounding air molecules are ionized to form positive and negative ions. The ionized air ions collide with the dust particles in the air, so that the dust particles are charged (usually positively charged or negatively charged). The charged dust particles are adsorbed onto the electrostatic precipitator 5 with opposite charges under the action of the electrostatic field, thereby capturing the dust in the air and preventing the dust from reattaching to the gift box 100.
[0033] As shown in Figure 1 and Figure 4 , the collecting assembly 3 includes a suction pipe 31, a blowing pipe 32 and a dust removal box 33. The two ends of the blowing pipe 32 are respectively in communication with the blowing port of the dust removal chamber 21 and the blowing port of the dust removal box 33, and the two ends of the suction pipe 31 are respectively in communication with the suction port of the channel 4 and the suction port of the dust removal box 33. The dust removal box 33 injects airflow into the dust removal chamber 21 through the blowing pipe 32, the airflow flowing into the channel 4 blows the positive and negative ions generated by the direct current ion wind rod 6 to the surface of the gift box 100, eliminates the electrostatic adsorption force of the dust and neutralizes the charge, the airflow separates the dust from the box body, the electrostatic precipitator 5 adsorbs the dust in the channel 4 on its surface, and the airflow carries the adsorbed dust into the dust removal box 33 through the suction pipe 31, and the dust removal box 33 filters the airflow before being introduced into the blowing pipe 32, so that the airflow can be recycled.
[0034] Specifically, the dust removal box 33 is provided with a circulating air pump, which generates power for generating a circulating air flow. A filtering device, such as a bag filter or a filter cartridge dust collector, is arranged on the circulating line to filter and collect dust in the air flow.
[0035] As shown in Figures 3 to 5 The dust removal assembly 2 includes a dust removal cover 22 and a dust removal cover 23. The dust removal cover 23 is located between the dust removal cover 22 and the moving part 12, that is, the dust removal cover 22 and the dust removal cover 23 are arranged vertically. The dust removal cover 23 and the dust removal cover 22 form a dust removal chamber 21. The dust removal cover 22 is a thin-walled shell structure with an open bottom. The dust removal cover 23 is fixedly installed on the bottom of the dust removal cover 22.
[0036] The dust removal cover 23 is communicated with the air suction pipe 31, and the inside space of the dust removal cover 23 is gradually narrowed from the edge to the center, forming a tapered structure. Specifically, the dust removal cover 23 includes a cover body 231, which is fixedly arranged on the inside of the dust removal cover 22 along the length direction of the channel 4. The cover body 231 is fixedly connected with a first flow guide plate 232 and a second flow guide plate 233 on both sides along the width direction of the channel 4, respectively. The first flow guide plate 232 and the second flow guide plate 233 are fixedly connected with the dust removal cover 22, respectively. The first flow guide plate 232 and the second flow guide plate 233 are communicated with the dust removal chamber 21 and the channel 4. It is worth noting that the length direction of the channel 4 is the same as the advancing direction of the gift box 100, and the width direction of the channel 4 is perpendicular to the length direction of the channel 4, both of which are in the horizontal plane.
[0037] The first flow guide plate 232 is provided with a plurality of first through holes 234, which are communicated with the first chamber 211 and the channel 4. The second flow guide plate 233 is provided with a plurality of second through holes 235, which are communicated with the second chamber 212 and the channel 4. Preferably, the first through holes 234 are arrayed on the first flow guide plate 232, and the second through holes 235 are arrayed on the second flow guide plate 233.
[0038] Preferably, both ends of the cover body 231 along the vertical direction are open. One end of the cover body 231 is communicated with the channel 4, and the other end is communicated with the air suction pipe 31. The cover body 231 gradually shrinks upwards. Preferably, the cover body 231 is a hollow trapezoidal column. The tapered structure can accelerate the speed of the air flow when flowing to the narrow end, forming a high-speed air flow. The high-speed air flow can more effectively carry dust particles, improve the collection efficiency of dust, form a stronger negative pressure area at the narrow end, and enhance the negative pressure to more effectively suck away the dust. The concentrated air flow can more accurately control the movement direction of the dust, prevent the dust from escaping, make the air flow more stable, and improve the overall efficiency of the dust removal system.
[0039] Preferably, the top end surface of the cover body 231 abuts against the inner wall of the top end surface of the dust discharge cover 22, and the top opening of the cover body 231 communicates with the top end surface of the dust discharge cover 22, so that the air suction pipe 31 directly communicates with the cavity of the cover body 231, that is, the air suction pipe 31 communicates with the channel 4. The cover body 231 extends to the top inner wall of the dust discharge cover 22 to divide the dust removal chamber 21 into the first cavity 211 and the second cavity 212 which communicate with each other.
[0040] The first flow guide plate 232 divides the first cavity 211 and the channel 4, and the second flow guide plate 233 divides the second cavity 212 and the channel 4. The first flow guide plate 232 and the second flow guide plate 233 are both arranged to be inclined towards the moving part 12, that is, the first flow guide plate 232 and the second flow guide plate 233 are both arranged to be at an angle. The inclined flow guide plates can guide the airflow to the gift box 100 on the moving part 12, and make the airflow more concentrated and orderly. Preferably, the first flow guide plate 232 and the second flow guide plate 233 are symmetrically arranged about the cover body 231. More preferably, the first flow guide plate 232, the cover body 231, the second flow guide plate 233 and the moving part 12 jointly form a channel 4 in the shape of a trapezoid. The symmetrically arranged flow guide plates form a convection between them, promote the mixing of the airflow, prolong the residence time of the airflow in the dust removal area, significantly improve the capture and separation efficiency of the dust, and make the airflow more evenly distributed in the dust removal area, avoiding too strong or too weak airflow in local areas and optimizing the airflow distribution.
[0041] The blowing pipe 32 communicates with a flow divider cover 34 which is fixed to the top of the dust discharge cover 22. The flow divider cover 34 has at least one input end and at least two output ends. The input end communicates with the output end of the blowing pipe 32. At least one output end of the flow divider cover 34 communicates with the first cavity 211, and at least another output end of the flow divider cover 34 communicates with the second cavity 212, so as to uniformly divide the airflow supplied by the blowing pipe 32.
[0042] Preferably, the top of the dust discharge cover 22 is provided with a first air hole 221 and a second air hole 222. The first air hole 221 communicates with the first cavity 211, and the second air hole 222 communicates with the second cavity 212. The flow divider cover 34 is in the shape of a long strip. The flow divider cover 34 is a thin-walled piece with an inner groove. The open end of the flow divider cover 34 is fixed to the top of the dust discharge cover 22. The first air hole 221 and the second air hole 222 communicate with the inner cavity of the flow divider cover 34. The blowing pipe communicates with the flow divider cover 34. The blowing pipe outputs airflow to the inner cavity of the flow divider cover 34. The inner cavity of the flow divider cover 34 is fully filled with airflow. The airflow in the flow divider cover 34 is uniformly input to the first cavity 211 through the first air hole 221 and to the second cavity 212 through the second air hole 222, so that the airflow in the first cavity 211 and the airflow in the second cavity 212 are uniform, and the airflow passing through the first flow guide plate 232 and the airflow passing through the second flow guide plate 233 are more uniform.
[0043] Preferably, the electrostatic bar 5 is fixed at the communication between the chamber of the cover 231 and the passage 4 or inside the chamber of the cover 231. Preferably, the two direct current ion wind bars 6 are fixed at the connection between the first guide plate 232 and the cover 231 and the connection between the second guide plate 233 and the cover 231 respectively. More preferably, the electrostatic bar 5 and the direct current ion wind bar 6 are arranged along the moving direction of the gift box 100.
[0044] The dust removal assembly 2 is provided with the baffle 7 on both sides along the moving direction of the gift box 100, and a certain space is reserved between the baffle 7 and the moving part 12 for the smooth passing of the gift box 100. Specifically, the width between the bottom of the baffle 7 and the moving part 12 is greater than the height of the gift box 100, so as to avoid the blocking of the gift box 100 by the baffle 7 and ensure the entry of the gift box 100 into the passage. The baffle 7 partially closes the two ends of the passage 4, effectively blocks the dust from the outside into the passage 4, thereby reducing the possibility of secondary pollution of the gift box 100 during the dust removal process.
[0045] The above embodiments are only for illustrating the technical concept and characteristics of the present application, and the purpose is to enable those skilled in the art to understand the content of the present application and implement it, and cannot limit the protection scope of the present application. For those skilled in the art, it is obvious that the present application is not limited to the details of the above exemplary embodiments, and can be implemented in other specific forms without departing from the spirit or basic characteristics of the present application, therefore, from any point of view, the embodiments should be regarded as exemplary and non-limiting, the scope of the present application is defined by the appended claims rather than the above description, therefore, all changes falling within the meaning and scope of the equivalent elements of the claims are intended to be included in the present application.
