Description

Technical Field

[0001] This utility model relates to the field of air dryer technology, and in particular to a high-efficiency air knife air dryer. Background Technology

[0002] An air knife dryer is a device that uses high-pressure airflow to quickly dry the moisture, oil stains, or other liquids on the surface of an object.

[0003] A reference can be made to an existing document, an air knife dryer (CN219674722U). The reference describes how the toothed part of an incomplete gear drives the gear to rotate at a certain angle, thereby moving the support plate at the bottom. As a result, the left and right air knives on both sides of the bottom of the support plate will deflect at a certain angle.

[0004] In existing air knife dryers, air knives are generally divided into straight-hole air knives, oblique-hole air knives, etc. The surface of the air knife has multiple air outlet holes at equal intervals. However, since the air knife and the pipeline are fixedly installed as a whole, the air outlet angle of the air knife is fixed, and the air supply range is limited. Furthermore, as shown in the above literature, the existing technology will set up a drive mechanism to drive the air knife disc to rotate horizontally. However, during the horizontal rotation of the air knife, it will drive the air supply pipeline to rotate synchronously, which will continuously pull on the air supply pipeline and cause damage to the pipeline. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a high-efficiency air knife dryer. This invention utilizes a hydraulic rod in the air supply assembly to drive the connecting column longitudinally, and a hinged design to change the tilt angle of the air knife, thereby adjusting the air blowing angle. Simultaneously, a belt drives the air guide tube to rotate. Because the air guide tube has a built-in bearing, the exhaust pipe can supply air into the air guide tube without rotating itself with it.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A high-efficiency air knife dryer includes: a casing, inside which are arranged three sets of air supply components. Air guide tubes in the air supply components are rotatably connected to the top of the casing. Each air guide tube is hollow and has a bearing embedded and fixed at its top. A hydraulic rod is fixedly installed at the center of the bottom of each air guide tube. A connecting column is fixedly connected to the telescopic end of the hydraulic rod. Multiple air knives are hinged to the side of the connecting column. A slider is hinged to the bottom of each air knife. The slider is slidably mounted above a slide rail. The slide rail is connected to the side wall of the air guide tube via a connecting frame.

[0008] The present invention is further configured such that a servo motor is fixedly mounted on the top of the chassis via a bracket, and transmission wheels are rotatably connected to both sides of the top of the chassis, one of which is fixed below the output end of the servo motor.

[0009] The present invention is further configured such that belts are fitted onto the outer sides of both of the two drive wheels, and drive grooves for fitting belts are provided on the surfaces of both the drive wheels and the air guide tube.

[0010] The present invention is further provided with multiple transmission protrusions arranged in a ring at equal intervals in the transmission groove on the surface of the air guide tube.

[0011] The present invention is further configured such that multiple air knives and air guide tubes are connected by corrugated hoses, and multiple exhaust ports are equidistantly opened on the surface of the air knives.

[0012] The present invention is further configured such that a vortex fan is fixedly installed on the upper rear side of the chassis, the air outlet of the vortex fan is connected to an exhaust pipe, and each branch of the exhaust pipe is connected to an air supply head, and each air supply head is fitted and fixed in the inner ring of the bearing.

[0013] The present invention is further configured such that a transmission mechanism is provided inside the chassis, and openings are provided on both sides of the chassis to allow the transmission mechanism to pass through.

[0014] The beneficial effects of this utility model are as follows:

[0015] 1. During operation, the air knife dryer uses a hydraulic rod in the air supply assembly to drive the connecting column to move longitudinally. The air knives are all hinged to the outside of the connecting column, and multiple connecting frames connect the slide rails on the side of the air duct. The slider above the slide rail is hinged to the other end of the air knife. This design allows the tilt angle of the air knife to be adjusted when the connecting column moves longitudinally, thereby expanding the air supply range and improving the drying efficiency.

[0016] 2. During the air delivery process, the air knife dryer drives the transmission wheel to rotate via the operation of the servo motor, which in turn drives the two air guide tubes to rotate via the belt. The vortex fan delivers air into the air guide tubes through the exhaust pipe and the air delivery head. The top of the air guide tube is embedded with a fixed bearing, and the air delivery head is fixed to the inner ring of the bearing. This ensures that the rotation of the air guide tube will not drive the exhaust pipe to rotate, thus avoiding pulling on the exhaust pipe and achieving air delivery and rotation at the same time.

Therefore, they should not be construed as limitations on this patent.

[0025] In the description of this patent, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "setting" should be interpreted broadly. For example, they can refer to a fixed connection or setting, a detachable connection or setting, or an integral connection or setting. Those skilled in the art can understand the specific meaning of the above terms in this patent according to the specific circumstances.

[0026] Reference Figure 1-4 A high-efficiency air knife dryer includes: a housing 1, a conveying mechanism 2 is provided inside the housing 1, the bottles to be dried are placed on the conveying mechanism 2 and the bottles are conveyed inside the housing 1, the front end of the housing 1 is connected to a double door, and three sets of air supply components are provided inside the housing 1.

[0027] Specifically, such as Figure 3 As shown, the main body of the air supply assembly is the air guide tube 8. The air guide tube 8 is rotatably connected to the upper inner wall of the casing 1. The air guide tube 8 has a hollow design inside and multiple corrugated hoses 18 are connected to the bottom. Air is supplied to multiple air knives 16 through the multiple corrugated hoses 18.

[0028] Specifically, a hydraulic rod 14 is fixedly installed at the bottom center of the air duct 8. The telescopic end of the hydraulic rod 14 is connected to a connecting column 15. One end of the air knife 16 is hinged to the side of the connecting column 15. At the same time, multiple connecting brackets 12 are integrally welded to the side of the air duct 8. Slide rails 13 are welded to the bottom of the multiple connecting brackets 12.

[0029] Furthermore, sliders 17 are slidably mounted above each slide rail 13, and the sliders 17 are limited to sliding operation above the slide rail 13.

[0030] Meanwhile, the slider 17 is hinged to the other end of the air knife 16.

[0031] In this embodiment, the hydraulic rod 14 drives the connecting column 15 to move longitudinally, thereby changing the tilt angle of the air knife 16. At the same time, the slider 17 moves linearly above the slide rail 13, thereby changing the air outlet angle of the air knife 16 and expanding the air supply range.

[0032] Specifically, such as Figure 1-2 As shown, a servo motor 5 is fixed to the upper left side of the chassis 1 by two brackets. At the same time, a transmission wheel 6 is rotatably connected to both sides of the upper end of the chassis 1. One of the transmission wheels 6 is fixed to the output end of the servo motor 5, and the two transmission wheels 6 are connected by a belt 7.

[0033] Furthermore, such as Figure 3 As shown, annular transmission grooves 9 are provided on the surfaces of both the transmission wheel 6 and the air guide tube 8. The belt 7 is sleeved in the transmission grooves 9. Multiple transmission protrusions 10 are distributed in annularly in the transmission grooves 9 on the surface of the air guide tube 8. The transmission protrusions 10 can improve the transmission effect of the belt 7 on the air guide tube 8.

[0034] Specifically, such as Figure 1-2 As shown, a vortex fan 3 is fixedly installed on the upper rear side of the casing 1. A mountain-shaped exhaust pipe 4 is connected to the air outlet of the vortex fan 3. (See also...) Figure 4 As shown, the three branches of the exhaust duct 4 are all connected to the air supply head 19.

[0035] Furthermore, such as Figure 3As shown, a bearing 11 is embedded and fixed at the top of the air guide duct 8, and the air supply head 19 is fixed in the inner ring of the bearing 11. Therefore, when the air guide duct 8 rotates, the outer ring of the bearing 11 can rotate with it, and the air supply head 19 will not rotate. This allows the exhaust pipe 4 to continuously supply air into the air guide duct 8 through the air supply head 19, while the exhaust pipe 4 will not rotate with the air guide duct 8, thus avoiding pulling on the pipeline.

[0036] Working principle: When using this utility model, during operation, the hydraulic rod 14 in the air supply assembly drives the connecting column 15 to move longitudinally. The air blades 16 are all hinged to the outside of the connecting column 15. At the same time, multiple connecting brackets 12 connect the slide rails 13 to the side of the air guide tube 8. The slider 17 above the slide rail 13 is hinged to the other end of the air blade 16. This design allows the tilt angle of the air blades 16 to be adjusted when the connecting column 15 moves longitudinally, thereby expanding the air supply range and improving the drying efficiency. During the air supply process, the operation of the servo motor 5 drives the transmission wheel 6 to rotate, and then drives the two air guide tubes 8 to rotate through the belt 7. The vortex fan 3 delivers air into the air guide tube 8 through the exhaust pipe 4 and the air supply head 19. The top of the air guide tube 8 is embedded and fixed with a bearing 11. The air supply head 19 is fixed to the inner ring of the bearing 11, so that the rotation of the air guide tube 8 will not drive the exhaust pipe 4 to rotate, avoiding pulling on the exhaust pipe 4, and realizing air supply and rotation at the same time.

[0037] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
