[0002] With the development of science and technology, fans are increasingly used in daily life and industrial production. As the core component of the fan, the performance and service life of the fan blades directly affect the overall performance of the fan. In actual use, dust and dirt are easily accumulated on the surface of the fan blades, which not only affects the heat dissipation efficiency and air flow effect of the fan, but also increases energy consumption, and even causes corrosion and damage to the fan blades, shortening their service life. Therefore, it is of great practical significance to develop an effective fan blade dust prevention technology. Traditional fan blade dust prevention methods mainly use physical protective covers and film sticking. However, these methods have certain limitations.

[0036] The embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0037] like Figure 1-9As shown, the present invention is a UV printing production equipment for preparing a dust-proof film for fan blades, comprising a frame 1, a crossbeam 10 is mounted on the frame 1, a UV printing mechanism 2 that can move left and right on the crossbeam 10 is provided, and an annular conveyor belt 3 for placing fan blades and cooperating with the UV printing mechanism 2 according to a preset program to complete the printing of a dust-proof film on the fan blades is provided on the frame 1 below the crossbeam 10, and a fan blade positioning mechanism 4 for positioning the fan blades thereon is provided at the rear end of the annular conveyor belt 3. Traditional fan blade protective films, such as protective films made of wood grain materials, are generally fixed to the fan blades by pasting. This method not only makes the production process too complicated, but also easily generates bubbles, and the protective film is also prone to falling off in the later stage. In addition, during the operation of the fan, the protective film is also prone to generate static electricity and absorb dust. The present application prints a layer of protective film on the fan blades by UV printing, which can make the production process simpler, improve production efficiency, and reduce production costs. At the same time, the generated protective film does not generate static electricity during use and does not absorb dust in the environment.

[0038] A tearable protective film 5 is provided on the endless conveyor belt 3. In order to improve production efficiency and reduce the cost of subsequent maintenance, the endless conveyor belt 3 is used in conjunction with the UV printing mechanism 2. After printing is completed, the endless conveyor belt 3 transports the ink to the next process. In order to prevent the ink of the UV printing mechanism 2 from being sprayed onto the endless conveyor belt 3, which makes it difficult to clean or replace the ink later, a protective film 5 is provided on the endless conveyor belt 3. When there is too much ink, the protective film 5 is directly torn off and a new protective film 5 is pasted. In this application, the material of the protective film 5 is a polyurethane-based protective film (such as 3M TM 7070UV) and PET films (such as 3M TM 5932 release film) both materials have good flexibility, chemical resistance and tearability. In addition, since the fan blades are placed on the protective film 5, when printing, when the endless conveyor belt 3 moves, the fan blades and the protective film 5 cannot move relative to each other. Therefore, the surface of the protective film 5 can be set to a non-slip structure, such as increasing the roughness.

[0039] like Figures 1 to 3 and Figure 5As shown, the fan blade positioning mechanism 4 includes a plurality of limit blocks 40 and a driving assembly 41 for driving the plurality of limit blocks 40 to rotate. The limit blocks 40 are formed with limit grooves 42 corresponding to the shape of the front end of the fan blades. The driving assembly 41 includes a rotating shaft 43 provided on the frame 1 and rotatably matched with the frame 1 and a first driving motor 44 provided on the frame 1 for driving the rotating shaft 43 to rotate. The driving assembly 41 also includes a plurality of connecting members 45 corresponding to the limit blocks 40. The connecting member 45 includes an arc connecting rod 450 and a linear connecting rod 451 connected to the end of the arc connecting rod 450. One end of the linear connecting rod 451 is connected to the rotating shaft 43, and one end of the arc connecting rod 450 is detachably connected to the limit block 40. The limit block 40 is provided with a sensor 46 for detecting the fan blades, and the frame 1 is also provided with a protective cover 48 for covering the fan blade positioning mechanism 4. In order to improve production efficiency, multiple blades will be placed on the circular conveyor belt 3 for simultaneous printing, and for the convenience of positioning, a blade positioning mechanism 4 is set. When printing the blades, the blades are placed at the input end of the circular conveyor belt 3 by manual or mechanical equipment, and the circular conveyor belt 3 runs into the limit groove 42. The limit groove 42 will prevent the blades from continuing to move. When there are blades in all the limit grooves 42, the sensor 46 detects that all the blades are in place, and the circular conveyor belt 3 stops running. The first drive motor 44 drives all the limit blocks 40 to separate from the blades and rotate to the other side, so that it will not affect the operation of the UV printing mechanism 2. In addition, when the limit block 40 is limiting, there is a gap between the bottom of the limit block 40 and the circular conveyor belt 3, so that the bottom of the limit block 40 will not contact the circular conveyor belt 3, and the circular conveyor belt 3 or the protective film 5 will not be scratched.

[0040] The limit block 40 and the arc-shaped connecting rod 450 are detachably connected to facilitate replacement when printing fan blades of different models. It should be noted that the arc-shaped connecting rod 450 can be connected to the limit block 40 by bolts.

[0041] like Figure 4 , Figure 6As shown, as a further solution of this embodiment, the UV printing mechanism 2 includes a horizontal plate 20 that slides with the crossbeam 10 and a vertical plate 21 that slides up and down with the horizontal plate 20. The UV printing mechanism 2 also includes a nozzle group 22 arranged on the vertical plate 21, a UV curing lamp 26 arranged on the left and right sides of the nozzle group 22, and a nozzle driving member 23 arranged on the vertical plate 21 and cooperating with the horizontal plate 20 to drive the vertical plate 21 to move up and down. The nozzle driving member 23 can be driven by a screw rod. The screw rod and the motor driving method are conventional technologies and will not be repeated in this application. The nozzle group 22 is set to be able to move up and down, so that it can adapt to fan blades of different thicknesses. The UV printing mechanism 2 also includes an ink gas absorption component 24 respectively arranged between the UV curing lamp 26 and the nozzle group 22. A visual positioning sensor 25 for detecting the fan blade is provided on the front end of the nozzle group 22. By setting the visual positioning sensor 25, it is possible to further detect whether the fan blade has deviation. After the deviation is detected, the UV printing mechanism 2 is compensated to complete the printing of the dustproof film. In addition, by arranging UV curing lamps 26 on both sides of the nozzle group 22, the curing efficiency can be accelerated, and since the UV curing lamps 26 are arranged on both sides of the nozzle group 22, bidirectional printing can be achieved.

[0042] like Figure 5 As shown, as a further solution of this embodiment, the arc connecting rod 450 has an arc angle of 90°. After the arc connecting rod 450 is set to 90° and matched with the linear connecting rod 451, the motor can drive the limit block 40 to be horizontally placed above the endless conveyor belt 3 after rotating 90°, and can be reset after rotating 90° in the opposite direction, so as to efficiently complete the positioning without taking up too much space.

[0043] like Figure 5 As shown, as a further solution of this embodiment, the fan blade positioning mechanism 4 also includes a reinforcing rod 47 for connecting a plurality of limit blocks 40. After the reinforcing rod 47 is provided, the limit blocks 40 can be connected into one, which can make the whole structure more stable and the positioning more accurate.

[0044] like Figure 8 , Fig. 9As shown, as a further solution of the present embodiment, a front-end positioning mechanism 6 for pre-positioning the fan blades is provided on the frame 1 at the input end of the endless conveyor belt 3, and the front-end positioning mechanism 6 includes a plurality of rotating shafts 60 rotatably arranged on the frame 1 and a plurality of rubber wheels 61 arranged on the rotating shafts 60, and the front-end positioning mechanism 6 also includes a rotating driving member 7, a cover plate 62 and a plurality of guide strips 63, the rotating driving member 7 is arranged on one side of the frame 1, and is used to drive the plurality of rotating shafts 60 to rotate synchronously, the cover plate 62 is arranged on the frame 1, and an avoidance opening (not shown in the figure) is formed on the cover plate 62 for exposing the upper end of the rubber wheel 61, and a plurality of guide strips 63 are arranged on the cover plate 62 at intervals, and a guide channel 64 corresponding to the limit block 40 is formed between adjacent guide bars 63, and the rubber wheel 61 is correspondingly located in the guide channel 64. By setting up the front-end positioning mechanism 6, the fan blades can be preliminarily positioned. The staff or mechanical equipment can directly place the fan blades in the guide channel 64. The rubber wheel 61 will drive the fan blades to transition to the annular conveyor belt 3, and the annular conveyor belt 3 will transport the fan blades to the limiting groove 42 for positioning, which greatly improves production efficiency.

[0045] like Figure 8 , Fig. 9 As shown, as a further solution of this embodiment, the rotating drive member 7 includes a second driving motor 70, a driving synchronous wheel 71, a plurality of synchronous belts 72 and a plurality of driven synchronous wheels 73. The second driving motor 70 is arranged on one side of the frame 1, and the driving synchronous wheel 71 is arranged on the output shaft of the second driving motor 70. Three rotating shafts 60 are provided and arranged side by side. Two driven synchronous wheels 73 are provided on the rotating shaft 60 located in the middle and the rotating shaft 60 on the left side thereof. A driven synchronous wheel 73 is provided on the rotating shaft 60 on the right side of the middle rotating shaft 60, and is connected to one of the driven synchronous wheels 73 on the middle rotating shaft 60 through a synchronous belt 72. Another driven synchronous wheel 73 on the middle rotating shaft 60 is also connected to the corresponding driven synchronous wheel 73 on the rotating shaft 60 on the left side through a synchronous belt 72. The driving synchronous wheel 71 on the second driving motor 70 is correspondingly connected to the driven synchronous wheel 73 on the rotating shaft 60 on the left side through a synchronous belt 72. It can be seen from the above structure that when the rubber wheel 61 rotates, it is driven by the second drive motor 70, and drives each rotating shaft 60 to rotate through the active synchronous wheel 71, the driven synchronous wheel 73 and the synchronous belt 72, thereby driving the rubber wheel 61 to rotate, and the rubber wheel 61 can transport the fan blades to the annular conveyor belt 3 for preliminary positioning.
