Description

Technical Field

[0001] The utility model relates to the technical field of air knives for bottle drying machines, in particular to an air knife for bottle drying machines. Background Art

[0002] Bottle dryers are essential equipment in the bottle manufacturing and packaging industries. After washing bottles, they use high-speed airflow to quickly remove any residual moisture from the inner and outer surfaces of the bottles, ensuring their cleanliness and dryness, and ensuring that qualified bottles are ready for subsequent processing. However, the traditional air knife design of bottle dryers has numerous shortcomings, limiting drying efficiency and quality. For example, the nozzle design of traditional air knives is often fixed and cannot be adjusted to the shape and size of the bottle. This results in uneven drying and can cause areas of over-dryness or over-wetting on the bottle surface. This not only affects the drying quality of the bottles but can also cause unnecessary scratches or damage to the bottle surface. Therefore, a bottle dryer air knife was proposed to address these issues. Utility Model Content

[0018] The principles and features of the present invention are described below in conjunction with the accompanying drawings. The enumerated embodiments are only used to explain the present invention and are not used to limit the scope of the present invention.

[0019] Example 1

[0020] Reference Figure 1 and Figure 2The utility model provides a bottle dryer air knife, including a dryer 2 and a drying conveyor belt 9, including a control mechanism, a detection mechanism and a steering mechanism, the control mechanism including a PLC controller 1, the PLC controller 1 is electrically connected to the dryer 2, the detection mechanism includes an infrared sensor 3 electrically connected to the PLC controller 1, the infrared sensor 3 is arranged on the conveyor belt 9 and is used to detect whether there are bottles 10 on the conveyor belt, the steering mechanism includes an air knife duct, a wind direction plate 7 and an electric telescopic rod 4 electrically connected to the PLC controller 1, the fixed end of the electric telescopic rod 4 is arranged on the side wall of the air knife duct, the air knife duct is connected to the air outlet of the dryer 2, one end of the wind direction plate 7 is hingedly arranged at the connection between the air knife duct and the air outlet of the dryer 2, and the other end of the wind direction plate 7 is slidably connected to the movable end of the electric telescopic rod 4.

[0021] For example, when the infrared sensor 3 arranged on the conveyor belt 9 detects the bottle 10 to be dried, the PLC controller 1 sends a signal instruction to the dryer 2, so that the wind from the dryer 2 passes through the air outlet to reach the air knife duct. At the same time, the PLC controller 1 sends a signal instruction to the electric telescopic rod 4, so that the moving end of the electric telescopic rod 4 pushes the wind direction plate 7 downward, thereby changing the direction of the wind from the dryer 2 to form a top-to-bottom wind direction aligned with the bottle 10 to be dried on the conveyor belt for uniform drying from top to bottom, thereby avoiding local over-drying or over-wetting, and thus improving the drying efficiency and quality.

[0022] The air knife ducts are respectively arranged obliquely at both ends above the conveyor belt 9.

[0023] For example, the air knife ducts are obliquely arranged at both ends above the conveyor belt 9, so that the wind from the fan can be directed to dry 180 degrees on both sides of the bottle 10, thereby avoiding leaving dead corners that are not dried.

[0024] It also includes an air volume control mechanism, and the wind direction control mechanism includes a solenoid valve 5 electrically connected to the PLC controller 1. The solenoid valve 5 is arranged at the air outlet of the hair dryer. In order to adapt to different drying effects, the opening and closing size of the solenoid valve 5 can be controlled by the PLC controller 1, and then the air volume of the hair dryer 2 is controlled by the opening and closing size of the solenoid valve 5.

[0025] In the above embodiment, the PLC controller 1, the hair dryer 2, the infrared sensor 3, the electric telescopic rod 4 and the solenoid valve 5 can all adopt existing models well known to those skilled in the art.

[0026] Example 2

[0027] Based on the above embodiment, the difference between this embodiment and the above embodiment is:

[0028] Reference Figure 3 and Figure 4 The detection mechanism includes a dust sensor 6, which is arranged on the side wall of the air knife duct and is electrically connected to the PLC controller 1.

[0029] For example, in order to avoid the problem of dust accumulation caused by long-term blowing of the dryer 2, the dust in the air knife duct can be monitored by the dust sensor 6, so as to prompt the staff to clean it in time. When the dust detected by the dust sensor 6 exceeds the set dust threshold, the dust sensor 6 will give an audible and visual prompt. The dust threshold is set independently by the staff according to the actual situation.

[0030] The air knife pipe is detachably connected to the air outlet of the dryer 2.

[0031] For example, in order to facilitate the cleaning of the air knife duct, the air knife duct and the air outlet of the hair dryer 2 can be set to be detachably connected, and when cleaning is required, the air knife duct can be removed for cleaning.

[0032] The outside of the air knife duct is covered with a noise reduction cotton layer.

[0033] For example, in order to reduce the noise of the dryer 2, a noise reduction cotton layer may be covered on the outside of the air knife duct to reduce the noise.

[0034] In the above embodiment, the PLC controller 1 and the dust sensor 6 can both be existing models known to those skilled in the art. The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
