Description

Technical Field

[0001] The invention relates to the field of machinery, in particular to the technology of blow dryers. Background Art

[0002] Bottles, cans and other containers are relatively moist after filling, and they need to be dehydrated and dried before packaging or laser engraving.

[0003] At present, air knife dryer is a commonly used equipment for drying bottles and cans. The air knife dryer uses an air compressor to compress the air to the required pressure, and the compressed air is sent to the air knife part through a pipe. The air knife is generally designed to have a specific flat blade shape and a specific angle. The compressed air is discharged at a high speed through the flat blade to generate a strong and uniform airflow to dry the moisture on the bottles and cans.

[0004] Existing air knife dryers require large air knives regardless of the size of the area being dried, which results in a relatively large overall volume of the air knife dryer system and high energy consumption. In addition, it is difficult to adjust the air knife blowing position, and each adjustment takes a long time to change the position and angle of the blade, which seriously affects production efficiency. Summary of the invention

[0005] The object of the present invention is to provide a capillary nozzle blow dryer with all-round adjustment to solve at least one of the above technical problems.

[0006] The technical problem solved by the present invention can be achieved by adopting the following technical solutions:

[0012] The ball joint structure includes a ball bowl and a hollow ball head;

[0013] The side of the air distribution pipe facing the conveyor belt is fixedly connected to the ball bowl through a hollow metal pipe;

[0014] A mouthpiece is provided on the exposed side of the ball head, and the opening diameter of the mouthpiece is 2.5mm to 3.5mm;

[0015] The air distribution pipe, ball bowl, ball head and mouthpiece are sequentially connected to form an air blowing path;

[0016] Above the conveyor belt and below the nozzle array, infrared detection switches are arranged along the conveying direction of the conveyor belt to form an infrared detection switch array;

[0017] Infrared detection switch array signal connection control system;

[0018] After receiving the signal sent by the infrared detection switch array, the control system controls the opening of the electric control valve to connect the high-pressure air pipe to supply air to the blowing air path for drying.

Through the ball joint structure, the position of the nozzle can be adjusted arbitrarily within the adjustable range of the ball joint structure. The opening aperture of the nozzle is set in the range of 2.5mm to 3.5mm to form capillary holes. High-pressure gas can pass through the capillary holes to form strong wind. The beneficial effect of the capillary nozzle is that, on the one hand, it can simplify the structure and reduce the overall volume of the dryer; on the other hand, it can make the blown wind more concentrated, and can accurately control the direction and intensity of the wind, thereby improving the efficiency of drying the moisture on the bottle and can.

[0020] In the above design, an infrared detection switch array is arranged along the conveying direction of the conveyor belt. The function of the infrared detection switch array is to detect whether there are objects to be dried within the range of the nozzle array. The signal of the existence of the objects to be dried is connected to the control system. The control system controls the electric control valve to open and connect the high-pressure air pipe. The beneficial effect is that it saves gas source and reduces waste.

[0021] Furthermore, at least three air inlet interfaces are provided, and at least three air inlet interfaces are evenly distributed at the top of the air distribution pipe.

[0022] In the above design, at least three air inlet interfaces are provided and evenly distributed above the air distribution pipe.

[0034] The metal ring is sleeved on the mouthpiece, and at least two locking screws are pressed against the mouthpiece;

[0035] The ultrasonic wave emission direction of at least four transducers is toward the direction of the blowing nozzle. When the air blowing path is started for drying, the ultrasonic device is started at the same time to ultrasonically atomize the moisture to be dried.

[0036] In the above design, at least four transducers are mounted around a metal ring, which is sleeved on the mouthpiece and fixed to the mouthpiece by a locking screw. The blowing direction of the mouthpiece is consistent with the direction of the ultrasonic wave emitted by the transducer. This connection method between the mouthpiece and the transducer is simple in structure and easy to install.

This connection method between the nozzle and the transducer is more compact in structure and can reduce space occupation.

The beneficial effect is that the drying efficiency of the hair dryer is improved.

[0041] Furthermore, brackets are provided on both left and right sides of the conveying direction above the conveyor belt, and nozzle systems are provided on the brackets on both sides.
