In order to improve the durability of the fan mesh cover, it is often necessary to apply an anti-rust coating to the fan mesh cover during processing and production. In order to ensure the coating effect of the anti-rust coating, the fan mesh cover needs to be cleaned and dried.

[0003] In the prior art, hot air drying is usually used to dry the cleaned fan mesh cover. Due to the grille-shaped structure of the fan mesh cover, a large number of water droplets are likely to remain in the numerous pores in the fan mesh cover after water washing.

[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0020] Embodiment: This embodiment provides a drying and cooling device for fan screen processing, see Figure 1 - Fig.12Specifically, it includes two symmetrically arranged side panels 1, a rotating shaft 101 symmetrically arranged front and back is rotatably installed between the left and right side panels 1, and a conveying wheel 102 symmetrically arranged left and right is fixedly installed on the rotating shaft 101. A conveying belt 103 is connected with a transmission sleeve between the two corresponding conveying wheels 102. A plurality of evenly distributed shaft seats 104 are fixedly installed on the outer side of the conveying belt 103. A servo motor 105 for driving the rotating shaft 101 to rotate is fixedly installed on the outer side of the side panel 1. A transversely arranged cross bar 2 is rotatably connected between the two corresponding shaft seats 104. The side panel 1 on the left is provided with a plurality of cross bars 2 that are adapted to the moving tracks of the plurality of cross bars 2. An annular groove 202, a first gear 203 arranged in the annular groove 202 is fixedly installed on the left end of the cross bar 2, the annular groove 202 is divided into four parts, upper and lower, front and rear, a first rack 204 meshing with the first gear 203 is fixedly installed on the inner end wall below the upper part of the annular groove 202, a grabbing mechanism is installed on the cross bar 2, a drying box 5 is sleeved on the outer side of the middle position of the left and right side panels 1, and the front and rear end walls of the drying box 5 are provided with a door hole 501 arranged between the left and right side panels 1, an air intake pipe 502 connected to the left and right side panels 1 is fixedly installed on the side end wall of the drying box 5, and the air intake pipe 502 is externally connected to a hot air circulation machine.

[0021] During the use of the device, the staff connects the device to an external power supply so that the external power supply provides power support for the device. Subsequently, the staff can control the device to be powered on and started. The drive shaft of the servo motor 105 is connected to one of the rotating shafts 101. After the servo motor 105 is powered on and started, its drive shaft rotates, which drives the rotating shaft 101 to rotate, and then drives the conveyor wheel 102 to drive the conveyor belt 103 to rotate continuously backward, driving a large number of evenly distributed cross bars 2 to move continuously from front to back above the side plate 1. During actual use, the staff places the fan mesh cover to be dried on the cross bar 2 from the front end of the device, and The grabbing mechanism grabs the fan mesh so that the fan mesh is firmly connected to the cross bar 2. During the continuous rotation of the conveyor belt 103, the fan mesh placed on the cross bar 2 is continuously conveyed backwards. During this conveying process, the cross bar 2 drives the first gear 203 fixed at its left end to move in the annular groove 202. With the engagement of the first gear 203 and the first rack 204, the first gear 203 can drive the cross bar 2 to rotate. In the process of the cross bar 2 driving the fan mesh to be conveyed backwards, the fan mesh can be driven to rotate, thereby realizing the swinging of the fan mesh. The centrifugal force generated when the fan mesh is swung can swing away most of the water droplets remaining on it.

[0022] The cross bar 2 carries the fan mesh cover through the front door opening 501 into the drying box 5, and then the external hot air circulation machine is powered on and started, and hot air is supplied to the drying box 5 through the air inlet pipe 502. The hot air is blown away and heated to blow away the moisture on the fan mesh cover, so as to achieve the drying operation of the fan mesh cover grabbed on the cross bar 2. The combination of swing dehydration and hot air drying can effectively improve the efficiency of separating the residual moisture in the gap of the fan mesh cover, which is conducive to improving the efficiency and effect of the staff using the device to dry the fan mesh cover. The dried fan mesh cover is led out from the door opening 501 at the rear of the drying box 5 under the carry of the cross bar 2, and is Under meshing, the fan mesh is still in a rotating and swinging state after being exported from the drying box 5. The swinging of the fan mesh can speed up the flow of air around it, and then the temperature of the fan mesh that is increased due to hot air drying can be quickly reduced, thereby achieving a rapid cooling operation of the fan mesh after hot air drying, which is convenient for the staff to directly grab the fan mesh later. When the fan mesh is carried by the cross bar 2 to the end of the device, the first rack 204 meshing with the first gear 203 no longer exists in the annular groove 202, which makes the cross bar 2 no longer drive the fan mesh to rotate and swing, and the staff can remove the dried and cooled fan mesh from the rear end of the device, and then perform other processing on the fan mesh.

[0023] When the device is in use, the staff can install it directly between the fan mesh cleaning process and other subsequent processes. The device can be used to dry the fan mesh during the transportation process, which is beneficial to improving the efficiency of fan mesh processing and production.

[0024] In the specific implementation process, Figure 3 and Figure 4 As shown, the grabbing mechanism is arranged above the cross bar 2, and a counterweight block 201 is fixedly installed on the bottom end wall of the cross bar 2. During the use of the device, the counterweight block 201 is fixedly installed on the bottom of the cross bar 2, so that the center of gravity of the counterweight block 201 is concentrated in the lower position. With the help of the counterweight of the counterweight block 201, after the cross bar 2 is connected with the fan mesh cover through the grabbing mechanism, in the absence of other external forces, the fan mesh cover is horizontally placed on the top of the cross bar 2, so that the cross bar 2 carrying the fan mesh cover is stable when it is transported to the end of the device, which is convenient for the staff to take the dried fan mesh cover from the end of the device, which is beneficial to ensure the stability of the device during actual use.

[0025] In the specific implementation process, Fig. 9As shown, a second rack 205 meshing with the first gear 203 is also fixedly mounted on the inner end wall above the upper part of the annular groove 202. The plurality of first racks 204 and the plurality of second racks 205 are arranged alternately from front to back. During the use of the device, the plurality of first racks 204 and the second racks 205 meshing with the first gear 203 are arranged alternately on the upper and lower inner end walls of the upper part of the annular groove 202. This enables the first gear 203 to mesh with the plurality of first racks 204 and the second racks 205 in sequence as it moves from front to back following the cross bar 2. When the first gear 203 meshes with the first rack 204 at the bottom, the first gear 203 is engaged with the plurality of first racks 204 and the second racks 205. When 04 is engaged, the cross bar 2 will be driven to drive the fan mesh cover to rotate clockwise. When the first gear 203 is engaged with the second rack 205 at the top, the cross bar 2 will be driven to drive the fan mesh cover to rotate counterclockwise. Under the engagement one by one, the rotation in the two directions is performed alternately, so that the cross bar 2 can drive the fan mesh cover to swing back and forth. The cyclic switching of the swinging direction can effectively increase the amplitude of the fan mesh cover being swung, which is beneficial to improving the effect of the device to detach water droplets from the fan mesh cover by swinging. There is enough distance between two adjacent cross bars 2 to avoid the collision between the two adjacent fan mesh covers in front and behind, thereby ensuring the stable operation of the device.

[0026] In the specific implementation process, Figure 4 , Figure 5 and Fig.12 As shown, the grabbing mechanism includes a second gear 3 that rotates vertically at the center position of the cross bar 2, a third rack 301 that meshes with the second gear 3 is horizontally slidable on the front and rear sides of the cross bar 2, and a column 302 that is movably inserted into the top of the cross bar 2 is vertically fixed at the end of the third rack 301, a tension spring 303 is fixedly connected between the left end of the third rack 301 located on the front and the inner end wall of the cross bar 2, a horizontally arranged insertion rod 304 is slidably inserted at the right end of the cross bar 2, and a hook 305 is fixedly installed at the right end of the insertion rod 304, and the left end of the insertion rod 304 is connected to a conversion joint 307 arranged in the cross bar 2, and the conversion joint A pull rope 308 is fixedly connected between 307 and the right end of the third rack 301 located on the front, a carrying plate 4 is arranged between the side plate 1 located on the right and the conveying wheel 102, and the edge position of the carrying plate 4 is surrounded by a first guide rail 401 and a second guide rail 402 adapted to the moving trajectory of the plurality of cross bars 2. The second guide rail 402 is arranged on the right side of the first guide rail 401 and corresponds to the positions of the first rack 204 and the second rack 205. The front and rear ends of the second guide rail 402 are arranged with an inclined transition connection to the first guide rail 401, and the hook 305 is hooked in the first guide rail 401 and the second guide rail 402.

[0027] During the use of the device, the connection between the fan grille and the cross bar 2 is achieved through the grabbing mechanism provided on the cross bar 2. When the fan grille is placed on the cross bar 2 by the staff, the left and right poles 302 are inserted into the gaps on the fan grille. During the continuous rotation of the conveyor belt 103 to drive the upper cross bar 2 to move backward, the hook 305 provided at the right end of the cross bar 2 will move from the first guide rail 401 to the range of the second guide rail 402. Since the second guide rail 402 is provided on the right side of the first guide rail 401, the hook 305 will be driven to move to the right. Under the connection of the insertion rod 304, the adapter 307 and the pull rope 308, the third rack 301 in the front of the cross bar 2 will be driven to overcome the tension spring. The elastic pulling force of 303 moves to the right, thereby making the column rod 302 fixed on the third rack 301 in front move to the right. In this process, with the help of the meshing reversing of the second gear 3, the third rack 301 at the rear moves to the left, driving the column rod 302 fixed on the third rack 301 at the rear to move to the left. The left and right column rods 302 move away from each other to form a support between the pores of the fan grille, thereby realizing the operation of automatically and firmly connecting the fan grille to the cross bar 2 during the backward transportation process. A groove is provided on the column rod 302. When the column rods 302 move away from each other to support and connect the fan grille, the groove can engage with the fan grille, which is beneficial to improve the firmness of the fan grille connected to the cross bar 2.

[0028] When the cross bar 2 carrying the fan grille moves to the rear end of the device, the hook 305 slides from the second guide rail 402 to the first guide rail 401, and the hook 305 moves to the left and resets. At this time, with the help of the elastic rebound of the tension spring 303, the two third racks 301 in the cross bar 2 drive the left and right column rods 302 to approach each other and reset. In this state, the grabbing mechanism no longer supports and connects the fan grille. After the drying and conveying is completed, the connection of the fan grille is automatically loosened, which is convenient for the staff to easily remove the fan grille on the cross bar 2. After the fan grille is firmly connected by the grabbing mechanism, it will rotate and swing due to the meshing of the first gear 203 and the first rack 204 and the second rack 205. Similarly, the grabbing mechanism will loosen the connection to the fan grille when the fan grille no longer rotates and swings.

[0029] The device switches the position of the hook 305 in the first guide rail 401 and the second guide rail 402 during the movement of the cross bar 2, cooperates with the elastic pulling of the tension spring 303, and the meshing reversing of the front and rear third racks 301 and the second gear 3, so that the device can automatically control the two poles 302 in the grasping mechanism to move closer to or farther away from each other on the cross bar 2, thereby realizing the connection and release of the fan grille. There is no need for staff operation and control, and the cross bar 2 can automatically realize the connection and release operation of the fan grille, which can effectively improve the operational flexibility and convenience of the device during actual use.

[0030] In the specific implementation process, Figure 5 As shown, the plug rod 304 is rotatably installed inside the right end of the cross bar 2, the adapter 307 is rotatably connected to the plug rod 304, the pull rope 308 is made of elastic material, and the stiffness of the pull rope 308 is twice the stiffness of the tension spring 303. During the use of the device, by rotatably installing the plug rod 304 inside the right end of the cross bar 2, and rotatably installing the adapter 307 at the end of the plug rod 304, when the cross bar 2 rotates to drive the fan grille to swing back and forth, it will affect the connection between the hook 305 and the first guide rail 401 and the second guide rail 402, and the two do not interfere with each other, which can effectively ensure the actual operation process of the device. At the same time, by using the pull rope 308 made of elastic material, when the third rack 301 is pulled and moved by the hook 305, if the movement of the column 302 above the third rack 301 is blocked, the third rack 301 can be prevented from being forced to move, and excessive supporting force applied to the pores on the fan mesh cover during the movement of the column 302 can be prevented, which is beneficial to ensuring the stability and safety of the fan mesh cover during the supported connection process, and enables the device to be adapted to connect fan mesh covers with different pores for drying operations, which to a certain extent improves the scope of application of the device during actual use.

[0031] In the specific implementation process, Figure 4 and Fig.10 As shown, a roller 306 is rotatably installed at the end of the hook 305, and the roller 306 is rollingly installed in the first guide rail 401 and the second guide rail 402. During the use of the device, the roller 306 is rotatably installed at the end of the hook 305, so that the roller 306 can roll in the first guide rail 401 and the second guide rail 402, which is beneficial to reduce the friction resistance of the hook 305 moving in the first guide rail 401 and the second guide rail 402, and is beneficial to ensure the stability and smoothness of the device when controlling the grasping mechanism by lateral movement of the hook 305 to the left and right.

[0032] In the specific implementation process, Figure 6 , Fig.10 and Fig.12As shown, a plurality of evenly distributed screw rods 403 are rotatably mounted on the side plate 1 located on the right side, and the screw rods 403 are threadedly connected to the bearing plate 4, and a transmission belt 404 is commonly connected to the numerous screw rods 403. During the use of the device, the right end of one of the screw rods 403 is fixedly connected to a crank, and the staff can adjust the position of the bearing plate 4. Under the condition that the left and right distances between the first guide rail 401 and the second guide rail 402 remain unchanged, the distances between the first guide rail 401 and the second guide rail 402 and the right end of the cross bar 2 are adjusted together. By adjusting the spacing, the initial position of the hook 305 is obtained. To change, and then change the initial position of the column 302 on the third rack 301. During this process, the staff holds the crank and rotates to drive the screw 403 to rotate. Through the transmission connection of the transmission belt 404, many screws 403 rotate synchronously. With the help of the threaded connection between the screw 403 and the supporting plate 4, the supporting plate 4 is driven to move left and right along the screw 403 to complete the adjustment operation of the initial position of the column 302. By adjusting the initial position of the column 302, the device can be adapted to connect and grab fan mesh covers of different sizes, which is beneficial to further improve the scope of application of the device in actual use.

[0033] In the specific implementation process, Figure 7 , Fig.10 and Fig.11 As shown, both upper and lower sides of the front and rear door openings 501 are equipped with horizontally arranged air curtain machines 503, and the air inlet of the air curtain machine 503 is arranged in the drying box 5, the air outlet of the air curtain machine 503 located at the top is vertically downward, and the air outlet of the air curtain machine 503 located at the bottom is vertically upward, the air inlet pipe 502 is fixedly connected to the lower part of the interior of the drying box 5, and a plurality of evenly distributed guide plates 504 are fixedly installed on the right end wall of the side panel 1 located on the left side, and the guide plates 504 are arranged corresponding to the air inlet pipe 502, and the right end of the guide plate 504 is arranged as an arc-shaped upward structure, and the right ends of the plurality of guide plates 504 are respectively arranged On the left side, middle position and right side inside the drying box 5, the air inlet of the hot air circulation machine is connected to the top of the drying box 5. During the use of the device, by respectively arranging multiple air curtain machines 503 on the upper and lower sides of the front and rear door openings 501, a vertical airflow curtain can be formed at the door opening 501, which restricts the exchange of airflow inside and outside the drying box 5, and to a certain extent blocks the hot air in the drying box 5, preventing the hot air transported to the drying box 5 from being directly blown out and dissipated. While ensuring that the fan mesh cover can enter and exit the drying box 5 smoothly, the stability of the hot air drying fan mesh cover in the drying box 5 can also be guaranteed.

[0034] By connecting the air inlet pipe 502 to the lower part of the drying box 5 and connecting the air inlet of the hot air circulation machine to the top of the drying box 5, the hot air from the drying box 5 can be recycled and reused, which is beneficial to reducing the energy consumption during the operation of the device and is convenient for realizing green and energy-saving production. In addition, by installing a large number of evenly distributed guide plates 504 at the lower part of the drying box 5, the drying box 5 is fixedly connected to the side plate 1 on the left side, which will not interfere with the operation of the conveyor belt 103 carrying the cross bar 2 in a circular movement. Since the guide plates 504 are arranged corresponding to the air inlet pipe 502, with the guidance of the guide plates 504, the hot air can act vertically upward on each fan mesh cover, and it can be ensured that the hot air is evenly dispersed in the drying box 5, which is beneficial to more comprehensive utilization of the hot air and to a certain extent improves the effect of the device using hot air to dry the fan mesh cover.

[0035] In the specific implementation process, Figure 8 and Fig.11 As shown, horizontally arranged cross frames 6 are fixedly installed on both the front and rear sides between the left and right side panels 1, and a support plate 601 with an upper end tilted backward is rotatably installed on the top of the cross frame 6, and the top of the support plate 601 is flush with the top of the cross bar 2 located above, and an elastic telescopic rod 602 is hinged between the back of the support plate 601 and the cross frame 6. During the use of the device, the top of the support plate 601 is flush with the top of the upper cross bar 2 under the elastic support of the elastic telescopic rod 602, and the cross bar 2 and the top of the support plate 601 cooperate with each other, so that the fan mesh cover can be stably placed when it is not connected by the grabbing mechanism. At the top of the frontmost cross bar 2 and the pallet 601, and at the top of the rearmost cross bar 2 and the pallet 601, when the cross bar 2 moves, the pallet 601 will be driven to swing downward under the extrusion caused by the movement of the cross bar 2, so that the cross bar 2 can smoothly pass over the top of the pallet 601, so that the existence of the pallet 601 will not affect the movement of the cross bar 2. When one cross bar 2 moves away from the pallet 601, another cross bar 2 will inevitably move closer to the pallet 601. The cross bar 2 and the top of the pallet 601 cooperate with each other to ensure the stability of the fan grille when it is initially placed or about to be taken out.

[0036] Specifically, the working principle and operation method of the present invention are as follows: After the servo motor 105 is powered on and started, it drives the conveyor wheel 102 to rotate, driving the conveyor belt 103 to rotate continuously. With the connection of the shaft seat 104, the plurality of cross bars 2 are moved from the top to the back and from the bottom to the front in a cycle. From the front of the device, the fan grille is placed on the frontmost cross bar 2 and the support plate 601, so that the column 302 is inserted into the hole on the fan grille. The cross bar 2 carries the fan grille to move backward, so that the hook 305 is transferred from the first guide rail 401 to the second guide rail 402, driving the hook The hook 305 moves to the right, and with the help of the connection between the plug rod 304, the adapter 307 and the pull rope 308, and the meshing reversal of the second gear 3 and the two third racks 301 at the front and rear, the two columns 302 on the cross bar 2 are driven to move away from each other and supported in the pores on the fan grille, so as to achieve a firm connection between the cross bar 2 and the fan grille. Subsequently, with the help of the meshing of the first gear 203 with the numerous first racks 204 and the second racks 205 in the annular groove 202, the cross bar 2 is driven to drive the fan grille to swing back and forth, and the fan grille is thrown out. The water drops on the dry fan mesh cover are removed. When the fan mesh cover enters the drying box 5, the hot air circulation machine is powered on and started, and hot air is supplied to the lower part of the drying box 5 through the air inlet pipe 502. With the guidance of many evenly distributed guide plates 504, the hot air acts vertically and evenly on the fan mesh cover. The swing dehydration and hot air drying cooperate with each other to ensure the drying efficiency of the fan mesh cover. After drying, the cross bar 2 carries the fan mesh cover and continues to move backward, and is guided out of the drying box 5. The fan mesh cover on the outside is no longer heated. With the help of the airflow generated by the swinging, the temperature is quickly reduced. When the fan grille is carried by the cross bar 2 and moved to the rear end of the device, the cross bar 2 no longer drives the fan grille to rotate, and the hook 305 slides back into the first guide rail 401 from the second guide rail 402, so that the hook 305 moves to the left, and cooperates with the elastic pulling of the tension spring 303 to drive the left and right columns 302 to approach each other and reset, loosening the connection to the fan grille. At this time, the fan grille is placed on the cross bar 2 and the rear support plate 601, which is convenient for the staff to take.

Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solutions and inventive concepts of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
