Description

Technical Field

[0001] This utility model belongs to the technical field of setting machines, and particularly relates to a static pressure box with stable air output. Background Technology

[0002] When the setting machine is working, it needs to blow air onto the upper and lower parts of the fabric to set the shape. The air is blown from the static pressure box to the upper and lower air blowing pipes, and then distributed to the air nozzles by the upper and lower air nozzles to blow air onto the fabric. In the current static pressure box, the air guide plates on both sides are symmetrically arranged about the fan. When the fan blows air, there are problems such as large air loss and unstable air velocity at the outlet. Utility Model Content

[0003] The purpose of this invention is to solve at least one problem of the prior art and to propose a static pressure box with stable air output.

[0004] To achieve the above objectives, this utility model proposes a static pressure box with stable air output, including a box body and a fan. The front of the box body is provided with an air outlet, and the inside of the box body is provided with a ventilation duct connected to the air outlet. The fan is eccentrically located inside the box body, and an arc-shaped air guide plate is provided on the outer side of the fan blades so that a vortex air field is formed inside the box body when the fan is working. The arc-shaped air guide plate is aligned with the ventilation duct.

[0005] Preferably, the front of the housing is provided with two rows of air vents, one above the other, which are separated by a partition.

[0006] Preferably, the partition has a rounded transition structure at the end near the ventilation duct.

[0007] Preferably, a vertical flow stabilizer is provided on the housing directly opposite the air outlet, and the ventilation duct is aligned with the vertical flow stabilizer.

[0008] Preferably, an arc-shaped air outlet is provided at the air outlet.

[0009] Preferably, the distance between the arc-shaped air guide plate and the fan gradually increases in a counterclockwise direction. Of course, the arc-shaped air guide plate can also be symmetrically arranged on the left and right outer sides of the fan.

[0010] The beneficial effects of this utility model are as follows: By setting the fan eccentrically inside the housing and setting an arc-shaped air guide plate on the outer side of the fan blades, a vortex air field is formed inside the housing when the fan is working, which can reduce the amount of air loss. The air generated by the fan is basically blown into the ventilation duct, reducing the noise generated by the airflow impacting the housing, and the air speed at the air outlet is also relatively stable.

[0011] The features and advantages of this utility model will be described in detail through embodiments and accompanying drawings. Attached Figure Description

[0017] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. The components of the embodiments of this application described and shown in the accompanying drawings can generally be arranged and designed in various different configurations. In the description of this application, it should be noted that the terms "inner," "outer," etc., indicating orientation or positional relationships are based on the orientation or positional relationships shown in the accompanying drawings, or the orientation or positional relationships commonly used when the product of this application is in use. They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application. Furthermore, the terms "first," "second," etc., are only used to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0018] In the description of this application, it should also be noted that, unless otherwise expressly specified and limited, the terms "setup" and "connection" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0019] The present invention will now be described in detail with reference to the accompanying drawings.

[0020] See Figure 1 , Figure 2 , Figure 3 and Figure 4This embodiment provides a static pressure box with stable air output, including a box body 1 and a fan 2. The front of the box body 1 is provided with an air outlet 11, and the inside of the box body 1 is provided with a ventilation duct 10 connected to the air outlet 11. The fan 2 is eccentrically located inside the box body 1, and an arc-shaped air guide plate 12 is provided on the outer side of the fan blades so that a vortex air field is formed inside the box body 1 when the fan 2 is working. The arc-shaped air guide plate 12 is aligned with the ventilation duct 10.

[0021] In this embodiment, refer to Figures 1 to 3 The front of the box 1 is provided with two rows of air outlets 11, one above the other. The two rows of air outlets 11 are separated by a partition, so that the static pressure box has two independent air outlets, which are respectively aligned with the upper and lower air nozzles on the stenter.

[0022] Further, see Figure 3 and Figure 4 The partition has an arc transition structure at one end near the ventilation duct 10, which reduces airflow impact when the airflow in the ventilation duct 10 goes up and down to the air outlets, further reducing air loss and noise.

[0023] In this embodiment, refer to Figure 3 and Figure 4 Inside the housing 1, there are multiple parallel vertical flow stabilizers 3 positioned directly opposite the air outlet 11. The ventilation duct 10 is aligned with the vertical flow stabilizers 3, which play a certain role in stabilizing the airflow, making the air output from the air outlet 11 more uniform and stable.

[0024] In this embodiment, refer to Figure 3 and Figure 4 An arc-shaped air outlet plate is provided at the air outlet 11 to reduce the airflow impact when the air is vented from the air outlet 11, further reducing air loss and noise.

[0025] In this embodiment, refer to Figure 3 The distance between the arc-shaped air guide plate 12 and the fan 2 gradually increases in the counterclockwise direction, further ensuring that the vortex air field inside the box is more stable.

[0026] The working process of this utility model:

[0027] During operation, the static pressure box with stable air output starts the fan 2. As the fan blades rotate, they drive the surrounding air to flow and form a vortex wind field. The arc-shaped air guide plate 12 guides the air generated by the fan into the ventilation duct 10. The air flows out of the ventilation duct and is stabilized by the vertical flow stabilizer plate before flowing from the air outlet 11 to the blower nozzle of the setting machine, thereby setting the surface of the fabric.

[0028] The above embodiments are illustrative of the present invention and are not intended to limit the present invention. Any simple modifications to the present invention are within the protection scope of the present invention.
