[0002] In existing technology, air knives are typically fixed to the mounting bracket of a coating machine with screws. The process of assembling and disassembling air knives on the coating machine requires two people working together: one uses an Allen wrench to loosen or tighten the screws, while the other assists in the assembly and disassembly, holding the air knife securely. If the air knife is not held firmly during assembly and disassembly, it may fall onto the marble, damaging the marble or even injuring someone's foot, posing a risk. Furthermore, this type of air knife mounting structure is cumbersome to assemble and disassemble; each assembly and disassembly requires loosening the screws, which is time-consuming due to limited space and the difficulty of turning the screws.

[0030] The realization of the objective, functional features and advantages of the present invention will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation

[0031] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0032] It should be noted that all directional indications (such as up, down, left, right, front, back, etc.) in the embodiments of the present invention are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indication will also change accordingly.

[0033] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0034] Furthermore, the use of terms such as "first" and "second" in this invention is for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of those features. Additionally, the word "and / or" throughout the text means including three parallel solutions; for example, "A and / or B" includes solution A, solution B, or a solution that simultaneously satisfies A and B. Furthermore, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of those skilled in the art to implement them. When the combination of technical solutions is contradictory or impossible to implement, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection claimed by this invention.

[0035] This invention proposes a quick-release structure for an air knife, which can be applied to equipment such as coating machines that can use air knives for drying, and is not limited to this.

[0036] Reference Figures 1 to 5 In one embodiment of the present invention, the quick-release structure of the air knife includes a fixed base assembly 10 and a movable assembly 20. The fixed base assembly 10 includes a fixed block 11 and a connecting block 12. The fixed block 11 is adapted to be fixed on the air knife 100, and the connecting block 12 is adapted to be connected to a coating machine. The fixed block 11 and the connecting block 12 are arranged adjacent to each other and are provided with corresponding insertion holes 11a. The movable assembly 20 is adapted to be fixed on the air knife 100. The movable assembly 20 includes a control member 21, a transmission mechanism 22, and a plug-in member 23. The control member 21 and the plug-in member 23 are connected through the transmission mechanism 22. The control member 21 is used to adjust the position of the plug-in member 23 so that it can switch between a first position and a second position. In the first position, the plug-in member 23 is inserted into the insertion hole 11a to connect and fix the fixed block 11 and the connecting block 12. In the second position, the plug-in member 23 is disengaged from the insertion hole 11a to separate the fixed block 11 and the connecting block 12.

[0037] It should be noted that, in this embodiment, the disassembly and assembly of the air knife 100 refers to the separation and connection of the fixing block 11 and the connecting block 12. The connecting block 12 is detachably fixed to the gantry of the coating machine. The fixing block 11 and the movable component 20 can both be integral structures of the air knife 100 or pre-assembled together during installation. The connection method between the components can be a snap-fit ​​connection, threaded connection, adhesive fixation, or welding fixation, etc., and is not limited here.

[0038] The control component 21 can be a pusher, lever, handle, or knob, etc.; the transmission mechanism 22 can be a power transmission structure such as a hinge drive or linkage mechanism; and the connector 23 can be a pin, locking pin, fixing rod, etc., which is not limited here.

[0039] It is understandable that when disassembling and assembling the air knife 100, only the control component 21 needs to be operated to change the position of the connector 23. Only one person is needed to complete the disassembly and assembly of the air knife 100. It is simple, convenient and quick, which effectively improves the convenience and safety of disassembly and assembly of the air knife 100, reduces disassembly and assembly time, and saves labor costs.

[0040] Reference Figures 1 to 4 In one embodiment, the quick-release structure of the air knife may further include a guide component 30, which is adapted to be fixed on the air knife 100, and the transmission mechanism 22 is slidably disposed on the guide component 30.

[0041] In this embodiment, the guide assembly 30 includes a guide seat 31 and a cover plate 32. The guide seat 31 is provided with a groove 31a extending along its length direction. The transmission mechanism 22 is provided with a slider 225, which is slidably disposed in the groove 31a. The cover plate 32 is covered on the groove 31a and is used to restrict the slider 225 from disengaging from the groove 31a.

[0042] The guide seat 31 can be fixed to the air knife 100 by screws, etc. The cover plate 32 can be locked to the guide seat 31 by screws. The guide seat 31 cooperates with the slider 225 of the transmission mechanism 22. By covering the slider 225 with the cover plate 32, the slider 225 can always be in the groove 31a of the guide seat 31, and the slider 225 will not be dislodged from the guide seat 31 due to external influences, which can effectively ensure the stability of force transmission.

[0043] Based on the above embodiments, further, mainly referring to Figure 2 and Figure 4 The transmission mechanism 22 may also include a rotating shaft 221, a rotating rod 222, a hinge rod 223, a connector 224, a connecting shaft 226, and a push block 227. The rotating shaft 221 is rotatably mounted on the guide seat 31 and connected to the control member 21. The rotating rod 222 is connected to the rotating shaft 221. The hinge rod 223 connects the rotating rod 222 and the connector 224. The slider 225 is located between the connector 224 and the connecting shaft 226. The push block 227 is fixed to the end of the connecting shaft 226. The plug-in member 23 is fixed to the end of the push block 227.

[0044] In this embodiment, the rotating shaft 221 is installed in conjunction with the circular hole on the guide seat 31. The rotating shaft 221 can rotate clockwise and counterclockwise along the circular hole of the guide seat 31. The rotating rod 222 can be locked onto the rotating shaft 221 with screws. The hinge rod 223 can be locked onto the rotating rod 222 and the connector 224 with shoulder screws. The two ends of the slider 225 can be locked onto the connector 224 and the connecting shaft 226 with screws respectively. The connecting shaft 226 is locked onto the threaded hole of the push block 227 with its own thread. The pin can be locked onto the push block 227 with screws.

[0045] In this embodiment, the bottom of the fixing block 11 may be provided with a limiting groove 11b, and the connecting block 12 is provided with a limiting part 121 that is adapted to the limiting groove 11b, so as to hang the air knife 100 on the mounting frame of the coating machine, thereby further improving the convenience and stability of the air knife 100 installation.

[0046] When installing the air knife 100, the limiting groove 11b on the fixing block 11 that is locked with the air knife 100 can be hung on the limiting part 121 of the connecting block 12 to hang the air knife 100 and its components on the connecting block 12 of the coating machine gantry. Then, the control member 21 is turned counterclockwise, and the hinge rod 223 is driven to move by the rotating shaft 221. Then, the connector 224 drives the slider 225 to move in the slide groove 31a of the guide seat 31, so that the connecting shaft 226 connected to the slider 225 drives the push block 227, so that the plug 23 is inserted into the plug hole 11a of the connecting block 12, thereby completing the installation of the air knife 100.

[0047] When disassembling the air knife 100, simply turn the control piece 21 in the opposite direction to disengage the connector 23 from the connector hole 11a of the connecting block 12, and then you can directly remove the air knife 100.

[0048] It can be seen that the disassembly and assembly process of the wind knife 100 is very convenient. What originally required two people to operate can now be done by one person, greatly reducing time and labor costs.

[0049] To further improve the stability of the air knife 100 installation, refer to Figures 1 to 5 In one embodiment, the guide seat 31 may be provided with a sliding groove 31a at both ends, and a cover plate 32 may be provided on both sliding grooves 31a.

[0050] In this embodiment, the rotating rod 222 passes through the rotating shaft 221, and both ends of the rotating rod 222 are connected in sequence to a hinge rod 223, a connector 224, a slider 225, a connecting shaft 226, and a push block 227. The two sliders 225 are slidably disposed in the two sliding grooves 31a, and each of the two push blocks 227 is provided with at least one plug-in member 23. There are two sets of fixed seat assemblies 10, and the two sets of fixed seat assemblies 10 are suitable for being disposed at both ends of the air knife 100. The plug-in members 23 located at both ends of the transmission mechanism 22 are respectively disposed corresponding to the two sets of fixed seat assemblies 10.

[0051] In other words, in this embodiment, the connection and separation of the two sets of plug-in components 23 and the two sets of fixed components can be completed by operating a single control component 21.

[0052] Furthermore, in order to make the connection between the fixed base assembly 10 and the movable assembly 20 more stable and reliable, that is, to further improve the stability and reliability of the air knife 100 installation, in one embodiment, a magnetic attraction component may be provided at the contact point of the push block 227 and / or the fixed block 11 to increase the connection strength between the fixed base assembly 10 and the movable assembly 20 after the plug-in 23 is inserted into the plug-in hole 11a.

[0053] To prevent the transmission mechanism 22 from pinching and injuring the operator during operation, refer to Figure 1 and Figure 2 In one embodiment, the quick-release structure of the air knife further includes a protective member 40, which is disposed on the fixing base assembly 10 or adapted to be fixed on the air knife 100.

[0054] In this embodiment, the protective component 40 can be a cover plate 32 or a cover, etc., and is not limited here.

[0055] Specifically, the protective component 40 is mainly used to prevent operators from accidentally placing their hands in the gap between the guide cover and the slider 225 when pulling the control component 21 of the transmission mechanism 22, thereby causing hand injuries.

[0056] In addition, to facilitate the adjustment of the air outlet angle of the air knife 100 and improve the efficiency of drying the electrode coating, the following is mainly referred to Figure 2 and Figure 5 In one embodiment, the connecting block 12 may be provided with an arc-shaped hole 12a, which is adapted to allow the locking member of the mounting block of the air knife 100 and the coating machine to pass through, so as to adjust the mounting angle of the air knife 100; the connecting block 12 is provided with an indicator 122, which is adapted to correspond to the scale on the mounting block, so as to indicate the tilt angle of the air knife 100 installation.

[0057] The present invention also proposes a coating machine, which includes an air knife quick-release structure. The specific structure of the air knife quick-release structure is as described in the above embodiments. Since the coating machine proposed in this invention includes all the solutions of all embodiments of the above air knife quick-release structure, it has at least the same technical effects as the above air knife quick-release structure, which will not be described in detail here.

[0058] The above description is merely an optional embodiment of the present invention and does not limit the patent scope of the present invention. All equivalent structural transformations made using the contents of the present invention's specification and drawings under the inventive concept of the present invention, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present invention.
