Description

Technical Field

[0001] The utility model relates to the technical field of textile post-processing, in particular to a hot air system with multiple air outlets. Background Art

[0002] In the traditional hot air hair blowing machine, the hot air is blown out through a rectangular chamber, which is welded from steel plates, and is difficult to manufacture. The hot air flow is prone to vortex and turbulence, resulting in wind loss. In addition, the air flow at each outlet is turbulent and uneven. Therefore, the traditional hot air system is difficult to adapt to production needs, so a hot air chamber with multiple outlets and uniform air outlet must be redesigned to meet the requirements of the hot air hair blowing machine for uniform heating at a horizontal temperature and wind speed. Summary of the invention

[0003] The technical problem to be solved by the utility model is to propose a hot air system with multiple outlets for uniform heating with transverse isothermal and constant wind speed in view of the deficiencies in the prior art.

[0004] The technical problem to be solved by the utility model is achieved through the following technical solution: a hot air system with multiple outlets for air discharge, comprising a wind knife and an air inlet system for providing hot air to the wind knife, wherein the wind knife is provided with an air outlet for blowing toward the fabric wind knife, and the characteristics are:

[0005] The air intake system comprises a hot air distribution chamber and an air intake duct.

[0006] The hot air distribution chamber is a cylindrical structure arranged in parallel with the wind knife, and an air inlet is arranged upward in the middle of the hot air distribution chamber, and the air inlet is connected to the air inlet duct through an air inlet elbow joint;

[0007] A set of air outlet mechanisms is provided at each end of the hot air distribution chamber.

[0008] Each set of air outlet mechanisms includes two air outlets, which are symmetrically arranged front and back with the axis of the hot air distribution chamber as the axis, and each of the two air outlets is connected to an air outlet elbow joint, and the outlets of the two air outlet elbow joints are arranged in opposite directions, one left and one right;

[0009] The air outlet elbow joints are all connected to the air knife through a connecting hose.

[0010] The technical problem to be solved by the utility model can also be further achieved through the following technical solution: the hot air distribution chamber has a cylindrical shape with spherical covers at both ends.

[0011] The technical problem to be solved by the utility model can be further achieved by the following technical solution: the two sets of air outlet mechanisms are symmetrically arranged with the air inlet of the hot air distribution chamber as the center.

[0012] The technical problem to be solved by the utility model can be further achieved through the following technical solution: an air volume regulating valve is installed at each air outlet elbow joint.

[0013] Compared with the prior art, the utility model adopts a cylindrical hot air distribution chamber structure to reduce the turbulence inside the wind bin and increase the regulating air valve. The air outlets of the hot air bin are arranged in a strictly symmetrical structure, and the operator can quantitatively adjust the air volume according to the needs through the graduated air valve to ensure the stable and consistent air volume of each air outlet, which not only reduces the difficulty of processing and manufacturing, but also improves the stability and uniformity of each air flow, and meets the use requirements of the hot air hair blowing machine for rapid horizontal isothermal and uniform heating of the product.

[0017] The specific technical solutions of the present invention are further described below. To make the purpose, technical solutions and advantages of the embodiments of the present invention clearer and to facilitate those skilled in the art to further understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below in combination with the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of them, and do not constitute a limitation on the rights thereof. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in the field without creative work are within the scope of protection of the present invention.

[0018] A hot air system with multiple air outlets, comprising an air knife 10 and an air inlet system for providing hot air to the air knife, wherein the air knife is provided with an air outlet blowing toward the fabric air knife, and the air inlet system comprises a hot air distribution chamber and an air inlet duct, wherein the hot air distribution chamber is a cylindrical structure arranged in parallel with the air knife, and an air inlet is arranged upwardly in the middle of the hot air distribution chamber, and the air inlet is connected to the air inlet duct through an air inlet elbow joint;

[0019] A group of air outlet mechanisms are respectively provided at the two ends of the hot air distribution chamber, and each group of air outlet mechanisms includes two air outlets, and the two air outlets are symmetrically arranged front and back with the axis of the hot air distribution chamber as the axis, and the two air outlets are respectively connected to an air outlet elbow joint, and the outlets of the two air outlet elbow joints are arranged in opposite directions, one left and one right; the air outlet elbow joints are connected to the wind knife through a connecting hose 9.

[0020] The hot air distribution chamber is cylindrical in shape, and has spherical covers at both ends.

[0021] The two sets of air outlet mechanisms are symmetrically arranged with the air inlet of the hot air distribution chamber as the center.

[0022] Each air outlet elbow joint is equipped with an air volume regulating valve.

[0023] Referring to the attached drawings, this embodiment provides a technical solution: a hot air warehouse with multiple outlets and uniform air outlet, comprising a welding flange 1, an air inlet duct (welded steel pipe one) 2, a welding elbow 3, a welding steel pipe two 4, a hot air distribution chamber 5, a welding steel pipe three 6, an air outlet elbow joint (welded single-sided extended elbow) 7, and an air volume regulating valve 8. In this solution, the welding flange 1, the welding steel pipe one 2, the welding elbow 3, and the welding steel pipe two 4 are welded together as the hot air warehouse air inlet and welded to the hot air distribution chamber 5. The hot air distribution chamber 5 has a cylindrical shape and spherical covers at both ends. The welding steel pipe three 6, the welding single-sided extended elbow 7, and the air volume regulating valve 8 are combined with an air outlet. By symmetrically arranging multiple air outlet combinations at both ends of the hot air distribution chamber, the air outlet is connected to the air knife air inlet through a hose.

[0024] Working principle: When a hot air bin with multiple outlets and uniform air flow works normally, the welding flange 1 is connected to the external air supply device, and the hot air enters the hot air distribution chamber 5 through the hot air bin air inlet. The hot air flow fills the hot air distribution chamber 5 and forms a certain pressure, and then flows out through the symmetrically arranged air outlets. The outflowing hot air reaches the wind knife and blows toward the fabric through the wind knife outlet. The outlet air flow rate can be adjusted by adjusting the air valve to ensure that the air flow at the wind knife outlet is stable and uniform.

[0025] The above embodiments only express several implementation methods of the utility model, in which the gas outlet is not limited to the welded single-side extended elbow, but can also be a straight pipe. The description in this example is relatively specific and detailed, but it cannot be understood as a limitation on the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several deformations and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model.
