Description
Technical Field
[0001] This utility model belongs to the field of glass cleaning machines, and specifically relates to an air knife with a rotating baffle for use in glass cleaning machines. Background Technology
[0002] After completing the glass cleaning process, the glass washing machine needs to place the glass on the air duct to dry it. However, since the size of the glass to be dried varies depending on the product requirements, when the glass size is small, the glass is placed on one part of the air duct, while the cold air is blown directly into the air from the other part of the air duct without drying, which wastes energy.
[0003] To address this, a Chinese patent discloses an air knife assembly for a glass washing machine (application number: 2018104897743), comprising: an air tank body with an air storage space inside; an air outlet slit connected to the air storage space along the length of the air tank body; at least one partition inside the air tank body, each partition dividing its internal space into two unit spaces, each unit space connected to the air outlet slit, all unit spaces constituting the air storage space; each unit space correspondingly having an air inlet pipe assembly; the air knife assembly has partitions inside, dividing the air storage space into two or more unit spaces, each unit space correspondingly having an air inlet pipe assembly; different numbers of air inlet pipe assemblies are connected according to different sizes of glass, thereby adjusting the air outlet range and saving energy.
[0004] However, each unit space of the aforementioned air knife assembly requires a corresponding air inlet pipe assembly, making the device structure complex and the air inlet pipe assembly occupying a large space. In actual use, each air inlet pipe assembly needs to be connected to an independent air supply mechanism. Cleaning equipment with multiple air supply mechanisms increases equipment costs. At the same time, the installation and arrangement of multiple air supply mechanisms and air inlet pipe assemblies also become new problems, and existing glass cleaning machines need to be improved. Utility Model Content
[0005] In view of the problems existing in the prior art, the purpose of this utility model is to improve the high equipment cost and complicated installation of the existing solution, and to provide an air knife for glass washing machine that can be unilaterally inlet, segmented air outlet and energy saving, specifically an air knife with a rotating baffle.
[0006] The present invention solves the above problems by adopting the following technical solution.
[0007] An air knife with a rotating baffle for a glass washing machine includes an air duct with an air outlet chamber inside. An air inlet is located on one side of the duct along its length, while the other side is closed. An air outlet slit is located on the side of the duct facing the glass. The air knife also includes a rotating baffle and a driving component mounted on the air duct. The rotating baffle is rotatably connected inside the air duct, and its rotation is controlled by the driving component. The rotating baffle can divide the air duct into multiple segments, and its shape can be changed by the driving component to isolate or connect the air duct, thus achieving partial or complete air outlet for the air knife.
[0008] Furthermore, the driving component includes a driving source, a connecting seat, a connecting rod, a connecting arm, and a rotating shaft. The connecting seat is fixedly connected to the movable end of the driving source, and the fixed end of the driving source is hinged to a fixed seat, which is fixed to the frame or duct. The connecting rod passes through the connecting seat and is fixedly connected to it. One end of the connecting rod is fixed to the connecting arm, and the other end of the connecting arm is fixed to the rotating shaft. The rotating shaft passes through the duct, and the rotating partition is fixedly connected to the rotating shaft and placed inside the duct.
[0009] Furthermore, the front and rear connecting holes are provided opposite to each other on the front and rear walls of the duct. The rotating shaft passes through the front and rear connecting holes and can rotate. The connecting arm is swaying and placed on the outside of the duct.
[0010] Furthermore, bearings are fitted between the rotating shaft and the front and rear connecting holes.
[0011] Furthermore, the shape of the rotating baffle matches the inner wall of the duct.
[0012] Furthermore, the rotating partition is provided with one or more partitions, and the corresponding driving components are provided with one or more units.
[0013] Compared with existing technologies, this invention allows for segmented airflow while maintaining a single air intake, simplifying the air intake mechanism of the air knife in the drying area of a glass washer. It achieves adjustable airflow range without requiring multiple air intake structures. By placing a rotating baffle inside the duct, selective partitioning is achieved. When the glass is small, only part of the drying area of the glass washer can be used; the rotating baffle blocks the duct, allowing only partial airflow and saving energy. When the glass is large, the entire drying area is used; the rotating baffle changes shape to allow the duct to be fully open, enabling full airflow. Thus, this invention achieves the single-sided air intake, segmented airflow, and energy-saving effects of the air knife, with a simpler overall structure. In this invention, the rotating baffle is rotatable, controlled by a drive component to rotate within the duct to partition or connect the duct, a clever and practical design.
[0014] This invention requires only a single air inlet, or even just a single fan, to control part or all of the air output from multiple air knives. Especially for duct structures divided into three or more sections, there is no need for too many openings on the duct for independent air intake. Simple and compact mechanical parts replace the complex and large blower and connecting pipes. The overall structure is simple and ingenious, and the pipe connection is more convenient.

[0018] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the specific embodiments of this application are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.
[0019] This embodiment provides an air knife with a rotating baffle for use in the drying area of a glass washing machine. In actual use, the drying area includes a fan (not shown in the figure) and multiple air knives arranged vertically opposite each other. The air knives are mounted on a frame (not shown in the figure), and the fan supplies air to the air knives. Figure 1-3 As shown, the air knife includes an air duct 1 with an air outlet chamber 2 inside. An air inlet 3 is provided on one side of the air duct 1 along its length, while the other side is closed. The side of the air duct 1 facing the glass has an air outlet gap 4. The air knife also includes a rotating partition 5 and a driving component 6 installed on the air duct 1. The rotating partition 5 can divide the air duct 1 into multiple segments. The rotating partition 5 is controlled by the driving component 6 to change its shape to isolate or connect the air duct, so as to realize partial or complete air outlet of the air knife.
[0020] In actual use, an air distribution box is installed between the fan and the air knife. The fan supplies air to the air distribution box, which has multiple air outlets, the number of which matches the number of air knives. The air distribution box and the air inlet 3 of each air knife are connected by flexible hoses. In this case, only one variable frequency fan can be used, and its power can be automatically or manually adjusted according to the actual air outlet gap of the air knife to ensure uniform airflow from the air knife, resulting in greater energy savings overall. Of course, multiple fans can also be used to supply air, and one or more fans can be switched on and off according to the actual usage of the air knife to ensure uniform airflow from the drying area of the glass washing machine, achieving the same energy-saving effect.
[0021] The fan and the air knife can also be directly connected via a flexible hose for air supply.
[0022] In this embodiment, the rotating partition 5 is rotatably connected between the front and rear walls of the air duct 1, and the rotation of the rotating partition 5 within the air duct 1 is controlled by the driving component 6.
[0023] Specifically, the duct 1 has a front connecting hole 11 and a rear connecting hole 12 opposite to each other on its front and rear walls. The driving component 6 includes a driving source 61, a connecting seat 62, a connecting rod 63, a connecting arm 64, and a rotating shaft 65. The connecting seat 62 is fixedly connected to the movable end of the driving source 61, and the fixed end of the driving source 61 is hinged to a fixed seat 66, which is fixed to the frame or the duct 1. The connecting rod 63 passes through the connecting seat 62 and is fixedly connected to it. One end of the connecting rod 63 is fixed to the connecting arm 64, and the other end of the connecting arm 64 is fixed to the rotating shaft 65. The rotating shaft 65 passes sequentially through the front connecting hole, the rotating partition 5, and the rear connecting hole. The rotating shaft 65 can rotate along the front connecting hole and the rear connecting hole, and is fixedly connected to the rotating partition 5. A bearing can also be fitted between the rotating shaft 65 and the front connecting hole and the rear connecting hole to make the rotation of the rotating shaft 65 more sensitive. The connecting arm 64 is swayably positioned on the outside of the duct 1.
[0024] The piston rod of the drive source 61 extends and retracts, causing the connecting rod 63 and the drive source 61 to swing adaptively, which in turn causes the connecting arm 64 to swing back and forth around the rotating shaft 65. The rotating shaft 65 then makes a circumferential movement, ultimately causing the rotating partition 5 to flip circumferentially.
[0025] In this embodiment, the drive source 61 is a cylinder, but it can also be other drive elements.
[0026] The shape of the rotating baffle 5 matches the inner wall of the air duct 1.
[0027] In this embodiment, a rotating baffle 5 is provided, located in the middle of the air duct 1. When the rotating baffle 5 is in a vertical state, that is, when the rotating baffle 5 is perpendicular to the air duct 1, the rotating baffle 5 divides the air duct 1 in the middle, and only the left side of the air duct 1 receives and discharges air. When the entire air duct 1 needs to discharge air, the drive source 61 drives the movable end to retract, causing the rotating baffle 5 to flip to the right, so that the rotating baffle 5 flips in the direction of air intake, avoiding backwind obstruction and causing airflow turbulence that affects the uniform air discharge of the air duct 1.
[0028] Of course, multiple rotating baffles 5 can be installed, thereby dividing the air duct 1 into multiple sections. Each rotating baffle 5 is driven by a separate drive unit 6, so that the air outlet area of each section can be controlled to accommodate the drying of glass of different widths. Small glass passes through one or more sections near the air inlet 3, while large glass can pass through the entire section.
[0029] The air knife with rotating baffle provided in this embodiment for a glass washing machine, compared with the prior art, can achieve segmented air outlet with a single air inlet, reducing the need for blowers and corresponding air inlet pipes in the drying area, effectively simplifying equipment space and reducing equipment costs. It overcomes the shortcomings of air knife assemblies, which require a corresponding air inlet pipe assembly for each unit space, resulting in a complex device structure and a large space occupation by the air inlet pipe assembly.
[0030] This embodiment requires only a single air inlet, or even just a single fan, to control part or all of the air output from multiple air knives. Especially for duct structures divided into three or more sections, there is no need to have too many openings on the duct for independent air intake. Simple and compact mechanical parts replace the complex and large blower and connecting pipes, resulting in a simple and ingenious overall structure and easier pipe connection.
[0031] The above description is merely a preferred embodiment of this application and does not constitute any limitation on this application. Any person skilled in the art can make many possible variations and modifications to the technical solution of this application, or modify it into equivalent embodiments, without departing from the scope of the technical solution of this application. Therefore, all equivalent changes made based on the shape, structure, and principle of this application without departing from the content of the technical solution of this application should be covered within the protection scope of this application.
