Description

Technical Field

[0001] The utility model relates to the technical field of automatic cleaning equipment, and more specifically, to a special air drying device for vehicles. Background Art

[0002] During the automobile production process, it is necessary to conduct a sealing test on the vehicle. The specific test method is as follows: Sprinkle water on the vehicle body to simulate the rain condition to detect the vehicle sealing performance. After the product vehicle passes through the rain-sealing test equipment, there are many water marks remaining on the vehicle body. This will cause abnormalities in the product quality inspection process and make it impossible to paste the vehicle body protection film; when there are a large number of water marks on the vehicle body, the vehicle body protection film cannot be pasted on the roof and the engine hood. At present, for this problem, the common temporary countermeasure is to arrange 2 full-time employees to manually wipe the water marks on the vehicle with cotton cloth; this measure has the following problems: 1. The employees who wipe the water marks have a relatively large labor load; 2. It is difficult to standardize the work process manually, and it is difficult to ensure the work effect. 3. The working hours required by the manual wiping method are long, which affects the work efficiency of automobile production. Therefore, it is necessary to adopt a special air drying device for vehicles after rain-sealing test to cancel 2 full-time positions, so as to improve the first-pass rate and the automation of the production line.

[0003] There is an existing Chinese utility model with the application number 202123070243.7, which discloses an air drying structure for a car wash machine, including a blowing component arranged on the top of a gantry. The blowing component includes a main body, a blower is installed in the main body, an air duct is arranged in the main body, at least two air nozzles are movably installed on the main body, the air nozzles are all communicated with the air duct, an angle adjustment mechanism is installed on the main body, and the angle adjustment mechanism is connected with the air nozzles. It also includes a visual recognition component, and the visual recognition component is electrically connected with the angle adjustment mechanism. Through the setting of the visual recognition component and the rotatable air nozzles, the vehicle model and the position of the vehicle about to pass under the blowing component can be recognized, so that the angle of the air nozzles can be adjusted, the water on the vehicle body can be blown out more easily, the water can flow down along the slope of the vehicle body, thus accelerating the air drying effect, and at the same time, the blowing coverage area is increased, further improving the air drying efficiency.

[0004] In the above technical solution, the air nozzles installed on the top of the main body lack a moving structure in the vertical direction, making it difficult to air dry vehicles of different specifications. Vehicles that are too tall cannot pass through the main body, and vehicles that are too short are too far from the air nozzles, making it difficult to effectively dry the roof. Summary of the Utility Model

[0005] To solve the above technical problems, the utility model provides a vehicle air drying device. The vehicle surface is dried by the wind blown out from the air knife. The air knife is installed on the frame through a moving mechanism, so that the air knife can move in the vertical direction and adjust the height of the air knife according to needs to ensure the drying effect.

Moving mechanisms are provided on both sides of the passage, and the air knives are slidably connected to the frame through the moving mechanisms, enabling the air knives to move in the vertical direction. Thus, air-drying operations can be carried out on vehicles of different heights, facilitating the adjustment of the air knives to have a suitable distance from the vehicle surface, ensuring the air-drying effect, and avoiding the situation where the vehicle cannot pass through the passage due to insufficient height of the air knives or the air output being weakened and unable to dry the vehicle surface due to excessive height of the air knives.

[0023] The technical solutions of the present utility model will be further specifically described below through specific embodiments in conjunction with the attached drawings:

[0024] Embodiment 1

[0025] Such as Figure 1As shown, a vehicle-specific air-drying device includes a frame 1, an air transfer station 2 and an air knife 3. A passage for vehicles to pass through is provided below the frame 1. The air transfer station 2 is installed above the frame 1. A moving mechanism 4 is installed on the frame 1. The moving mechanism 4 is located on both sides of the passage. Both ends of the air knife 3 are slidably connected to the frame 1 in the vertical direction through the moving mechanism 4. The air transfer station 2 is connected to the air knife 3 through an air duct. The air transfer station 2 can be connected to multiple fans through a pipeline. The air transfer station 2 can be connected to multiple fans to mix the air from different fans to ensure uniform air output. The air transfer station 2 is connected to the air knife 3 through a pipeline. The air knife 3 has a guiding effect on the air output to ensure that the air output can blow evenly across the surface of the car. A passage is provided below the frame 1 for vehicles to pass through. The wind blade 3 is installed on the frame, erected in the air, and located above the passage. When the car passes through, the fan is started, and the wind is blown to the vehicle below the wind blade through the wind blade 3. As the vehicle moves, the wind from the wind blade 3 blows to different positions of the vehicle, and finally the entire vehicle is dried. Moving mechanisms 4 are provided on both sides of the passage. The wind blade 3 is slidably connected to the frame 1 through the moving mechanism 4, so that the wind blade 3 can move in the vertical direction, thereby achieving air drying operations for vehicles of different heights, facilitating the adjustment of the wind blade 3 so that it has a suitable distance from the vehicle surface, ensuring the air drying effect, and avoiding the situation where the wind blade 3 is not high enough to measure through the passage or the wind blade 3 is too high to weaken the wind and cannot dry the vehicle surface.

[0026] like Figure 1 As shown, the moving mechanism 4 includes a slide rail 41, a slider 42 and a driving device. The slider 42 is installed on the slide rail 41 and is slidably connected to the slide rail 41. The slide rail 41 is vertically installed on the side frame 12. The two ends of the wind knife 3 are connected to the slider 42. The driving device is connected to the wind knife 3 to drive the wind knife 3 to move along the slide rail 41. There are two sliders 42, which are respectively installed at the two ends of the wind knife 3. The slider 42 is slidably connected to the slide rail 41. The wind knife 3 is restricted by the slide rail 41 and can only move along the length direction of the slide rail 41. At the same time, the slide rail 41 also has an anti-tilting effect on the wind knife 3. There are two slide rails 41, which are respectively installed on both sides of the channel through which the vehicle passes. The distance between the two slide rails 41 is the same as the length of the wind knife 3 and cannot be changed. The slider 42 is installed on the slide rail 41 and can only move along the length direction of the slide rail 41. When the wind knife 3 tilts, the length of the wind knife 3 in the horizontal direction becomes shorter, while the distance between the two slide rails 41 cannot be changed, and the slider 42 cannot be separated from the slide rail 41, resulting in the slider 42 and the slide rail 41 conflicting with each other, pulling the wind knife 3 back to a horizontal state, and finally preventing the wind knife 3 from tilting. The driving device can drive the slider 42 to move on the slide rail 41.

[0027] like Figure 1As shown in the figure, the driving device includes a motor 43, a synchronous pulley 44, and a transmission belt 45. The motor 43 is installed on the frame 1, and the synchronous pulley 44 is fixed on the frame 1. The four synchronous pulleys 44 are respectively located at the upper and lower ends of the two slide rails 41, and the motor 43 drives the synchronous pulley 44 located at the upper end of the slide rail 41 to rotate. The synchronous pulley 44 at the upper end of the slide rail 41 can be directly connected to the output shaft of the motor 43, or can be connected to the motor 43 through belt drive, gear drive or other transmission methods. The synchronous pulleys 44 located at both ends of the slide rail 41 are connected by a transmission belt 45, and a synchronous belt locking plate 46 is provided on the synchronous belt 45 connecting the two synchronous pulleys 44. The synchronous belt locking plate 46 is fixed on the slider 42. The motor 43 can provide driving force for the moving mechanism 4, realizing the automation of the operation of the moving mechanism 4 and reducing the workload of employees. The output end of the motor 43 is connected to the synchronous pulley 44 located at the upper end of the slide rail 41 through the synchronous belt 45, and the synchronous pulleys 44 located at the upper and lower ends of the slide rail 41 are also connected by the synchronous belt 45. When the motor 43 starts, the rotation of the output end of the motor 43 is transmitted to the synchronous pulley 44 located at the upper end of the slide rail 41 through the synchronous belt 45, causing the synchronous pulley 44 to rotate, and then driving the synchronous belt 45 wound around the synchronous pulleys 44 located at the upper and lower ends of the slide rail 41 to move. A synchronous belt locking plate 46 is installed on the synchronous belt 45, and the synchronous belt locking plate 46 is fixed to the slider 42. When the synchronous belt 45 moves, it drives the synchronous belt locking plate 46 to move, and then drives the slider 42 to move, and finally drives the air knife 43 fixed on the slider 42 to move.

[0028] As Figure 2As shown in the figure, second slide rails 47 are further provided on the inner side surfaces of both sides of the frame 1. Second sliders 48 are slidably connected to the second slide rails 47. The second slide rails 47 are parallel to the slide rails 41. A counterweight 49 is provided on the second slider 48. A second transmission belt 410 is further provided on the second slider 48. One end of the second transmission belt 410 is connected to the second slider 48. A fixed pulley 411 is further provided on the frame 1. The fixed pulley 411 is located directly above the second slide rail 47. The second transmission belt 410 is wound around the fixed pulley 411. The other end of the second transmission belt 410 is connected to the air knife 3. The function of the counterweight 49 is to balance the weight during lifting, so that the air knife 3 operates in a balanced state. The counterweight 49 and the slider 42 are respectively connected to both ends of the second synchronous belt 410. The weight of the counterweight 49 is the same as the weight of the air knife 3, so that both ends of the synchronous belt 410 are in force balance, ensuring that the movement of the air knife 3 will not be affected by its own gravity. At the same time, since the counterweight 47 has a certain weight, if the counterweight 47 is only suspended at the end of the second transmission belt 410, the counterweight 47 is prone to shaking, and then drives the air knife 3 to shake through the second transmission belt 410, seriously affecting the stability of the device. Therefore, the counterweight 49 needs to be fixed to the side frame 12, and only the degree of freedom of movement in the vertical direction is retained. A second slide rail 47 is further provided on the side frame 12. The second slide rail 47 is perpendicular to the ground. A second slider 48 is slidably installed on the second slide rail 47. The second slider 48 can only move along the length direction of the second slide rail 47. The counterweight 49 is fixed to the second slider 48, thereby restricting the counterweight 49 to only move in the vertical direction and avoiding the reduction of the device stability caused by the shaking of the counterweight 49.

[0029] Embodiment 2

[0030] This embodiment is similar to the above-mentioned Embodiment 1, the difference is that, as Figure 2 shown, the air knife 3 is of a hollow structure. A high-pressure hose quick connector 31 is provided on the air knife 3. The high-pressure hose quick connector 31 is connected to the air transportation transfer station 2 through a high-pressure hose. The high-pressure hose quick connector 31 is connected to the inside of the air knife 3. An air outlet 32 is opened on the bottom surface of the air knife 3. After the air output by the fan is integrated by the air transportation transfer device 2, it enters the hollow structure of the air knife 3 through a pipeline from the high-pressure hose quick connector 31. Since the high-pressure hose quick connector 31 is the air inlet and the pressure is relatively high, the air entering the air knife 3 will quickly diffuse in the direction of lower pressure until the hollow structure of the air knife 3 is filled, and then the air entering later will push the previously entered air out from the air outlet 32.

[0031] As Figure 2 shown, the air outlet angle of the air outlet 32 is adjustable. The orientation of the opening of the air outlet 32 will determine the direction of the air blown out from the air knife 3. The air outlet angle of the air outlet 32 makes the air outlet mode of the air knife 3 more diversified to adapt to different working requirements.

[0032] As Figure 1 shown, the air outlet 32 is arranged along the length direction of the air knife 3. The air outlet 32 is connected to the inside of the air knife 3, and the length of the air outlet 32 is wider than the width of the vehicle. In order to ensure that the device can dry the entire vehicle, it is necessary to ensure that the air outlet 32 of the air knife sweeps through every part of the vehicle during the process of the vehicle passing through the device. This requires that the air outlet 32 needs to have a certain redundancy relative to the vehicle. Therefore, the air outlet 32 should be longer than the width of the vehicle.

[0033] Embodiment 3

[0034] This embodiment is similar to the above Embodiment 1, except that, as Figure 2 shown, mounting plates 5 are installed below both ends of the air knife 3, sensors 6 are installed on the relative inner sides of the two mounting plates 5, and the sensors 6 are electrically connected to the motor 43. The sensors 6 are respectively located on the mounting plates 5 at both ends of the air knife 3. The sensor 6 at one end emits a signal, and the sensor 6 at the other end receives the signal. When the vehicle movement blocks the emission and reception of the signal of the sensor 6, the sensor 6 will emit an electrical signal to control the movement of the motor 43.

[0035] As Figure 2 shown, the mounting plate 5 is in a "T" shape. The sensor 6 is installed at the head of the "T" shape of the mounting plate 5. The tail of the "T" shape of the mounting plate 5 is connected to the lower surface of the air knife 3. The width of the head of the "T" shape of the mounting plate 5 is longer than the width of the air knife 3. A plurality of sensors 6 are provided and installed at both ends and the lowermost end of the head of the "T" shape of the mounting plate. When the device is started, the sensor 6 at the lowermost end detects the presence of the vehicle, and the sensor 6 emits an electrical signal to the motor 43 to stop its movement. Sensors 6 are also installed at the leftmost and rightmost ends of the head of the "T" shape of the mounting plate 5. Since the width of the head of the "T" shape of the mounting plate 5 is longer than the width of the air blower 3, the sensors 6 installed at the leftmost and rightmost ends can detect the presence of the vehicle before the vehicle touches the air knife 3 and control the movement of the motor 43 in advance to avoid collision between the air knife 3 and the vehicle. After the sensor 6 installed at the leftmost or rightmost end detects the presence of the vehicle, the sensor 6 emits an electrical signal to drive the motor 43 to move so that the air knife 3 moves upward until the vehicle does not block the emission and reception of the signal of the sensor 6, and then the air knife 3 stops moving.

[0036] As Figure 1 shown, a travel switch is further provided on the bottom surface of the air blower 3. The travel switch and the anti-collision strip switch are electrically connected to the motor 43. The main functions of the travel switch and the anti-collision strip switch are to ensure the safety of the device during operation. If a vehicle or an object hits the air knife 3, the travel switch will come into contact with the vehicle or the object first to issue an alarm and stop the operation of the device.

[0037] Obviously, the above embodiments of the present utility model are merely examples for clearly illustrating the present utility model, rather than limitations on the implementation manners of the present utility model. For those of ordinary skill in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all implementation manners here. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the claims of the present utility model.
