Description

Technical Field

[0001] This utility model relates to the field of textile printing and dyeing drying ovens, and in particular to a drying oven with an improved air jet structure. Background Technology

[0002] In the prior art, during printing, when the fabric to be printed comes into contact with the rubber guide belt, the fabric is adhered tightly to the rubber guide belt because a layer of adhesive is pre-coated on it and it does not move. After printing, the fabric enters the drying device, where it separates from the rubber belt. The fabric is then smoothly "attached" to the polyester guide belt by the rotating active roller and the pressure of the hot air nozzles before entering the drying room for drying.

[0003] Furthermore, according to existing patent application number CN220700693U, an improved air outlet structure oven is disclosed, comprising an oven body and further comprising: an air guide hood structure disposed inside the oven body for uniformly discharging airflow within the oven body; an air inlet mechanism, wherein an inward groove is provided on one side of the oven body and the air inlet mechanism is disposed within the inward groove; and an air guide mechanism disposed at the top of the oven body and connected to an external pipe for discharging exhaust gas from inside the oven body. This improved air outlet structure oven, through... The oven body has an internal air guide hood structure, which consists of an air guide end, an air outlet end, and a circulation end. This structure enables the uniform drying of fabric moving within the oven body. Simultaneously, through the cooperation of the air inlet and air guide mechanisms, exhaust gas is discharged from the oven body. However, the air outlet uses an exhaust hood. This exhaust hood can only blow air directly downwards and cannot be tilted, resulting in a significant amount of hot air escaping from the oven, causing substantial energy waste. Furthermore, the additional material required for the exhaust hood increases costs, leading to lower airflow direction and energy utilization. Utility Model Content

[0004] This application provides an oven with an improved air jet structure, which enhances the drying effect and improves energy efficiency, while also simplifying the structure by eliminating the need for an additional air outlet hood. In the prior art, the air outlet is equipped with an air outlet hood; however, this hood can only blow air directly downwards and requires additional materials, resulting in significant hot air leakage and low energy efficiency.

[0005] The technical solutions adopted in the embodiments of this application are as follows.

[0006] An oven with an improved air-jet structure includes an air inlet device, an air guide at the air outlet end of the air inlet device, a first air outlet at the air outlet end of the air guide, and a second air outlet at the air outlet end of the air guide. The two side plates of the air guide are angled open. The upper and lower side plates of the air guide extend inward. Air outlets are provided at both the upper and lower ends of the air guide. The first air outlet corresponds to the upper air outlet. The second air outlet corresponds to the lower air outlet. A plurality of the first and second air outlets are arranged in an array.

[0007] As a further improvement to the above technical solution: the bottom of the second air outlet is gradually tilted at an angle, thereby compressing the air pressure at the location of the second air outlet away from the air inlet device.

[0008] As a further improvement to the above technical solution: a first groove is provided on the inner side of the air guide; the first groove is triangular in shape.

[0009] As a further improvement to the above technical solution: a first air outlet is provided on the first air outlet; a first plate and a second plate are provided at the first air outlet; the first plate and the second plate are arranged in parallel; the first plate is shorter than the second plate; a plurality of first air outlets are provided and the first air outlets are relatively mirror images of each other on the first air outlet.

[0010] As a further improvement to the above technical solution: a second air outlet is provided on the second air outlet; each of the second air outlets is provided with the first plate and the second plate; the second air outlet is opened on the plate of the second air outlet facing the first air outlet.

The first air outlet has a first air vent, and the second air outlet has a second air vent. Both the first and second air outlets are equipped with a first plate and a second plate, with the first plate being shorter than the second plate to concentrate the airflow. The first air outlet is positioned mirror-imagely on the upper and lower sides of the first air outlet, while the second air outlet is positioned on the upper side of the second air outlet to guide the airflow and prevent direct blowing onto the fabric, thus reducing efficiency. The inner side of the air guide has a first groove, which is triangular in shape and provides space for fabric movement. The bottom of the second air outlet is gradually inclined at an angle, and the area of ​​the second air outlet furthest from the air inlet is smaller than the area of ​​the second air outlet closest to the air inlet. This strengthens the airflow onto the fabric, thereby enhancing the efficiency of drying the fabric while maintaining a simple structure. Attached Figure Description
