A rotating air knife

Abstract

This utility model discloses a rotary air knife, including a housing, an embedded driver body, a drive rotation air outlet, an air knife body at the bottom, and a circular air inlet at the top. This rotary air knife, with its embedded driver body, circular air inlet, and cylindrical housing, allows airflow to enter the driver body through the air inlet and exit through the drive rotation air outlet. The housing and air knife body rotate at high speed, while airflow simultaneously exits from the air knife body, causing the rotary air knife to rotate at high speed and blow air. The rotary air knife is driven to rotate at high speed by compressed air, simultaneously blowing a compressed air curtain onto the product surface. At high speed, the air curtain continuously impacts the product surface, greatly increasing the blowing force.

Description

Technical Field

[0001] This utility model belongs to the field of air knife technology, and in particular relates to a rotary air knife. Background Technology

[0002] An air knife is a device mainly used in industrial fields, especially in processes such as water cutting and drying, and chip removal. An air knife can remove moisture or dust from the surface of an object by using high-speed airflow. It is widely used in various industrial scenarios. In industrial dust removal, the air knife is fixed above the product. After the air knife is vented, it blows air onto the surface of the product for dust removal or water removal. The blowing force of the air knife depends on the adjustment of the inlet air pressure.

[0003] The air knives currently on the market have the following problems when used: In industrial dust removal, the air knife is fixed above the product and blows air onto the product surface for dust removal or water removal. The blowing force of the air knife depends on the adjustment of the air inlet pressure. The fixed blowing method has limited blowing force and is not convenient to install, requiring frequent maintenance and repair. Utility Model Content

[0020] To better understand the purpose, structure, and function of this utility model, a rotary air knife of this utility model will be described in further detail below with reference to the accompanying drawings.

[0021] like Figure 1-2As shown, this utility model discloses a rotary air knife, comprising a housing 2, an inlaid driver body 4, a drive rotation air outlet 3, an air knife body 1 at the bottom of the housing 2, and an air inlet 6 at the top of the housing 2. The air inlet 6 is circular, and the housing 2 is cylindrical. By inlaying the driver body 4 inside the housing 2, installing the drive rotation air outlet 3 inside the housing 2, installing the air knife body 1 at the bottom of the housing 2, and installing the air inlet 6 at the top of the housing 2, the air knife enters the driver body 4 from the air inlet 6 and is ejected from the drive rotation air outlet 3. The housing 2 and the air knife body 1 rotate at high speed, and the air is ejected from the air knife body 1 at the same time, causing the rotary air knife to rotate at high speed and blow air simultaneously. The rotary air knife is driven to rotate at high speed by compressed air, and at the same time, the rotary air knife blows the compressed air curtain 7 onto the product surface. At high speed, the air curtain 7 continuously blows the product surface, thereby greatly increasing the blowing force, resulting in good working stability and no need for maintenance.

[0022] An air intake airflow 8 is provided above the air inlet 6, and an air curtain 7 is provided at the bottom of the air knife body 1. By adding an air intake airflow 8 above the air inlet 6, it is convenient for the air inlet 6 to take in air. The air curtain 7 is provided at the bottom of the air knife body 1, and the air curtain 7 can continuously blow on the product surface to increase the blowing force.

[0023] The surface of the air knife body 1 is provided with mounting buckles 9, which are symmetrically distributed. By installing mounting buckles 9 on the surface of the air knife, it is convenient to fix the air knife body 1.

[0024] The surface of the air knife body 1 is provided with air knife slots 10, which are symmetrically distributed. By adding air knife slots 10 to the surface of the air knife, the internal airflow can be easily ejected from the inside of the air knife body 1.

[0025] The housing 2 has a fixed mounting rod 5 inside. One end of the fixed mounting rod 5 is hexagonal. By installing the mounting rod inside the housing 2, the air knife can be easily fixed and installed.

[0026] The working principle of this rotary air knife is as follows: First, install it in the required position. Choose horizontal, vertical, or diagonal installation according to the production line design. Secure it with bolts or an air inlet. The distance between the air knife tip and the target object should ideally be controlled between 10-100mm; the closer, the better. Adjustments should be made based on the performance of the high-pressure blower. Turn on the equipment power and adjust the parameters and settings to ensure the air knife can effectively cut the material. Place the material to be processed in front of the air knife, start the equipment, and adjust the speed and force parameters to enable the air knife to cut the material. Once installed, it can be used. The airflow 8 enters the fixed mounting rod 5 through the air inlet 6. This rod remains stationary. The airflow enters the driver body 4, and the driving airflow is ejected from the drive rotation outlet 3, causing the driver body 4 to rotate. The driver body 4 drives the outer casing 2 to rotate as well. Simultaneously, the air knife body 1 rotates with the outer casing 2. Airflow is ejected from the air knife gap 10 through the internal flow channel, generating an air curtain 7. This causes the rotating air knife to rotate at high speed while simultaneously blowing air. The rotating air knife is driven to rotate at high speed by compressed air, and at the same time, the rotating air knife blows the compressed air curtain 7 onto the product surface. At high speed, the air curtain 7 continuously blows onto the product surface, thereby greatly increasing the blowing force. When the air knife body 1 has been used for too long, it can be replaced by using the mounting clip 9. When using the air knife, safety operating procedures must be strictly followed to ensure the safety of oneself and others. In addition, different models of air knives have different applicable ranges and operating conditions, and appropriate equipment should be selected according to specific circumstances.

[0027] It is understood that this utility model has been described through some embodiments, and those skilled in the art will recognize that various changes or equivalent substitutions can be made to these features and embodiments without departing from the spirit and scope of this utility model. Furthermore, under the teachings of this utility model, these features and embodiments can be modified to adapt to specific situations and materials without departing from the spirit and scope of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed herein, and all embodiments falling within the scope of the claims of this application are within the protection scope of this utility model.
