[0032] The utility model provides an air supply device, which can be installed in automated production equipment such as an oven. The following will take the installation of the air supply device in an oven as an example for introduction. Figures 1 to 3 A preferred embodiment of the air supply device provided by the utility model is shown.

[0033] See also Figures 1 to 3 In this embodiment, the air supply device 100 includes a shell 1 and a deflector 2, the shell 1 forms at least two adjacent air outlets 11; the deflector 2 is arranged in the shell 1 and is located between the two adjacent air outlets 11, the deflector 2 extends along the air outlet direction of the air outlet 11, and the width of the deflector 2 gradually decreases in the air outlet direction.

[0034] Specifically, a plurality of air outlets 11 are usually formed on the shell 1, and the shapes, sizes and air outlet directions of the plurality of air outlets 11 are usually the same, and the air outlet direction of the air outlet 11 is perpendicular to the plane where the air outlet 11 is located. The following will take the plane where the air outlet 11 is located as a horizontal plane, and the air outlet direction of the air outlet 11 is from top to bottom as an example for introduction.

[0035] The upper end of the deflector 2 is arranged on the outer shell surface of the housing 1. The deflector 2 is located at the lower side of two adjacent air outlets 11, and the two adjacent air outlets 11 are arranged horizontally at intervals, and the deflector 2 is located between the two adjacent air outlets 11. The width of the deflector 2 is the size of the deflector 2 in the spacing direction of the two adjacent air outlets 11. The width of the deflector 2 gradually decreases from top to bottom, so that two deflector surfaces 21 corresponding to the two adjacent air outlets 11 are formed on the deflector 2. The two deflector surfaces 21 are two opposite surfaces of the deflector 2 in the spacing direction of the two adjacent air outlets 11.

[0036] A deflector 2 is installed between two adjacent air outlets 11 among the multiple air outlets 11. When the housing 1 is provided with N+1 air outlets 11, N deflectors 2 may be provided corresponding to the N+1 air outlets 11, so that a deflector 2 may be provided between any two adjacent air outlets 11. The following will take two air outlets 11 on the housing 1 and the deflector 2 between the two air outlets 11 as an example for introduction.

[0037] The air supply device 100 is located on the upper side of the mesh belt conveyor 200, and the two air outlets 11 on the housing 1 are opposite to the mesh belt of the mesh belt conveyor 200, so that the airflow from the two air outlets 11 can be blown to the bottles on the mesh belt. Figure 4 and Figure 5Since the deflector 2 is provided at the blind spot between the two air outlets 11, the deflector 2 can increase the flow rate of the airflow in the middle part under the two air outlets 11, so that the airflow blown out from the two air outlets 11 can be more uniform, and the deflector 2 is provided with two guide surfaces 21 corresponding to the two air outlets 11, and the airflow in the middle part under the two air outlets 11 is guided downward by the two guide surfaces 21, so that the airflow can flow downward smoothly and evenly, meeting the requirements of laminar flow, so that the airflow can be evenly blown to the bottle body on the mesh belt so that it is evenly heated, thereby effectively eliminating the blind spot between the two air outlets 11 and avoiding the problem of turbulence under the two air outlets 11.

[0038] The air supply device 100 of the utility model increases the flow rate of the air flow in the middle part below the two air outlets 11 by arranging a deflector 2 in the blind area between two adjacent air outlets 11, so that the air flow can flow downward smoothly and evenly and blow toward the bottle body evenly, effectively eliminating the blind area between the two adjacent air outlets 11 and avoiding the problem of turbulence generated below the two adjacent air outlets 11.

[0039] The two guide surfaces 21 can guide the airflow downward, and the guide surface 21 can be set in a curved surface or a flat surface. Figures 1 to 3 In this embodiment, the two guide surfaces 21 are both arranged in a plane.

[0040] Specifically, the surface of the deflector 2 close to the air outlet 11 is defined as the top surface of the deflector 2, the top surface of the deflector 2 is connected to the housing 1, and the top surface of the deflector 2 is parallel to the horizontal plane. The top surface of the deflector 2 is connected between the upper ends of the two deflector surfaces 21, and the two deflector surfaces 21 are inclined relative to the top surface of the deflector 2 along the spacing direction of the two adjacent air outlets 11. The two deflector surfaces 21 are set as inclined planes, so that the deflector surface 21 has a better effect of guiding the air downward and is not easy to generate vortices.

[0041] When the two guide surfaces 21 are arranged as inclined planes, the cross-sectional shape of the guide 2 can be arranged in a triangle or trapezoidal shape. Figures 1 to 3 In this embodiment, the deflector 2 is arranged in a triangular prism shape.

[0042] Specifically, the lower ends of the two guide surfaces 21 are connected, so that the cross-sectional shape of the guide 2 is a triangle, and the guide 2 is arranged in a triangular prism shape. When the guide 2 is arranged in a triangular prism shape, the air supply device 100 is simulated, and the simulation results show that the airflow blown out from the two air outlets 11 will be more uniform.

[0043] Optionally, see Figures 1 to 3In this embodiment, the two guide surfaces 21 have equal inclination angles relative to the top surface of the deflector 2. Since the two air outlets 11 are usually of the same shape and size, the corresponding inclination angles of the two guide surfaces 21 are equal or approximately equal.

[0044] Optionally, see Figures 1 to 3 In this embodiment, the width of one end of the deflector 2 close to the air outlet 11 is equal to the distance between two adjacent air outlets 11 .

[0045] Specifically, the end of the deflector 2 close to the air outlet 11 is the upper end of the deflector 2, and the width of the deflector 2 gradually decreases from top to bottom, and the width of the upper end of the deflector 2 is the width of the deflector 2 at the widest point, which is also the width of the top surface of the deflector 2. When the width of the upper end of the deflector 2 is equal to or approximately equal to the spacing distance between the two air outlets 11, the deflector 2 can completely cover the area between the two air outlets 11.

[0046] When the width of the upper end of the deflector 2 is equal to the spacing between the two air outlets 11 , the air supply device 100 is simulated, and the simulation results show that the airflows blown out from the two air outlets 11 are relatively uniform.

[0047] The specific shape of the air outlet 11 is not particularly limited. Figure 1 In this embodiment, the air outlet 11 is arranged in a square shape, and the spacing direction of two adjacent air outlets 11 is the direction of the length of one side of the air outlet 11.

[0048] Optionally, see Figure 1 In this embodiment, two adjacent air outlets 11 are symmetrically arranged with respect to the deflector 2 in the spacing direction of the two adjacent air outlets 11, which helps to avoid turbulence under the two air outlets 11, so that the airflow blown out from the two air outlets 11 can be more uniform.

[0049] Optionally, see Figure 1 In this embodiment, a flow equalizing plate 12 is installed at each air outlet 11 .

[0050] Specifically, the flow equalizing plate 12 is usually a mesh plate, and the flow equalizing plate 12 is installed to cover the air outlet 11, which is conducive to the airflow blown out from the air outlet 11 to be blown evenly to the bottle body.

[0051] Optionally, see Figure 1 and Figure 2 In this embodiment, the housing 1 includes at least one channel housing unit 1a, and an air outlet 11 is provided at one end of the channel housing unit 1a.

[0052] Specifically, the housing 1 may include one or more channel housing units 1 a , one or more air outlets 11 are provided at the lower end of each channel housing unit 1 a , and the upper end of each channel housing unit 1 a is connected to the fan 3 .

[0053] When a plurality of air outlets 11 are provided at the lower end of the duct housing unit 1 a , a deflector 2 may be provided between two adjacent air outlets 11 on one duct housing unit 1 a .

[0054] When a plurality of duct housing units 1 a are provided, the air outlets 11 of the plurality of duct housing units 1 a are flush with each other, and a deflector 2 may be provided between two air outlets 11 close to each other on two adjacent duct housing units 1 a .

[0055] Optionally, see Figure 1 In this embodiment, a plurality of air outlets 11 are provided at one end of the channel housing unit 1a along the first side length direction of the air outlet 11 at intervals, and a deflector 2 arranged in a direction perpendicular to the first side length direction is provided between two adjacent air outlets 11 on the channel housing unit 1a.

[0056] Specifically, the first side length direction of the air outlet 11 is the width direction or the conveying direction of the mesh belt conveyor 200. The following will take the first side length direction of the air outlet 11 as the width direction of the mesh belt conveyor 200 as an example for introduction, and the direction perpendicular to the first side length direction is the conveying direction of the mesh belt conveyor 200. The deflector 2 is arranged along the conveying direction of the mesh belt conveyor 200 so that the intersection line of the top surface of the deflector 2 and the guide surface 21 is parallel to the conveying direction of the mesh belt conveyor 200. The deflector 2 arranged along the conveying direction of the mesh belt conveyor 200 is defined as the first deflector 2a, and the first deflector 2a is arranged on the channel shell unit 1a.

[0057] Optionally, see Figure 2 In this embodiment, a plurality of channel housing units 1a are arranged side by side, and the plurality of channel housing units 1a are arranged along the second side length direction of the air outlet 11, and a deflector 2 arranged along a direction perpendicular to the second side length direction is provided between two air outlets 11 close to each other on two adjacent channel housing units 1a.

[0058] Specifically, the second side length direction of the air outlet 11 is perpendicular or approximately perpendicular to the first side length direction, then the second side length direction of the air outlet 11 is the conveying direction of the mesh belt conveyor 200, and the direction perpendicular to the second side length direction is the width direction of the mesh belt conveyor 200, and the deflector 2 is arranged along the width direction of the mesh belt conveyor 200 so that the intersection line of the top surface of the deflector 2 and the deflector surface 21 is parallel to the width direction of the mesh belt conveyor 200. The deflector 2 arranged along the width direction of the mesh belt conveyor 200 is defined as the second deflector 2b below, and the second deflector 2b is arranged between the two channel shell units 1a.

[0059] Optionally, see Figure 1 and Figure 2 In this embodiment, the channel housing unit 1a includes an air duct 13, a static pressure box 14 and a high-efficiency filter 15. The air duct 13 is connected to the static pressure box 14. The high-efficiency filter 15 is installed at one end of the static pressure box 14 away from the air duct 13. The high-efficiency filter 15 is connected to the air outlet 11 on the channel housing unit 1a in a one-to-one correspondence.

[0060] Specifically, the air duct 13, the static pressure box 14 and the high efficiency filter 15 are all installed in the box body 6 of the oven, and the fan 3 is installed on the box body 6. The upper end of the air duct 13 is provided with an air inlet of the channel housing unit 1a, the fan 3 is connected to the upper end of the air duct 13, the lower end of the air duct 13 is connected to the upper end of the static pressure box 14 (i.e., the air inlet of the static pressure box 14), and the lower end of the static pressure box 14 (i.e., the air outlet of the static pressure box 14) is connected to the high efficiency filter 15. The part of the box body 6 connected to the high efficiency filter 15 forms the air outlet 11, that is, the channel housing unit 1a includes a partial structure of the box body 6.

[0061] When the oven is working, the fan 3 draws air, which is pressurized and sent to the static pressure box 14 through the air duct 13, and then blown down from the air outlet 11 after passing through the high-efficiency filter 15. The air is guided by the inverted cone-shaped deflector 2 between the two air outlets 11, thereby increasing the flow rate of the airflow between the two air outlets 11, avoiding the generation of turbulence, and allowing the airflow to be evenly blown to the bottle body on the mesh belt conveyor 200.

[0062] Optionally, see Figure 1 In this embodiment, a return air box 4 is installed at the lower side of the mesh belt conveyor 200, and an air collecting tube 5 is installed at the air inlet of the fan 3.

[0063] Specifically, an air circulation channel is formed in the box 6, and the housing 1, the fan 3, the return air box 4, and the air collecting tube 5 are all arranged in the air circulation channel. After the airflow blown out from the air outlet 11 processes the bottles on the mesh belt, it passes through the return air box 4 and the air collecting tube 5 in sequence and then returns to the air inlet of the fan 3, and then blows to the next batch of bottles after passing through the fan 3.
