Description

Technical Field

[0001] This application belongs to the technical field of automatic car wash equipment, specifically relating to a blower and blower method for an automatic car wash production line. Background Technology

[0002] In existing technologies, the blower equipment used in automated car wash production lines is a core post-processing element of the car wash workflow, playing a crucial role. Its core function is to thoroughly dry the residual moisture on the car's surface after spray cleaning. This not only directly ensures the cleanliness of the vehicle's exterior, preventing the formation of scale and stains after residual moisture evaporates, but also prevents moisture from seeping into vehicle crevices and corroding metal parts and damaging electrical components. Furthermore, it directly affects the car wash cycle time, making it a key piece of equipment for ensuring the large-scale, efficient operation of automated car wash production lines. However, the mainstream blower equipment used in automated car wash production lines currently on the market still has many technical shortcomings and struggles to adapt to the diverse car wash needs of today.

[0003] In existing technologies, conventional drying equipment is limited by its structural design. The blowing mechanism mostly moves back and forth in a single straight line, resulting in a very limited blowing coverage area. It can only dry the flat area of ​​the vehicle's roof, failing to effectively cover the curved surfaces of the vehicle's sides, front and rear bumpers, tires, wheel arches, and other irregularly shaped parts. This leads to a large amount of residual moisture remaining after washing the vehicle, which not only affects the washing effect but may also pose a safety hazard in winter due to the freezing of residual moisture. To compensate for this deficiency, the industry generally adopts the improvement method of increasing the number of fans or increasing the output power of the fans. However, this method not only significantly increases the equipment manufacturing cost and operating energy consumption but also generates high-frequency noise exceeding 85 decibels, violating environmental emission requirements. At the same time, the layout of multiple fans increases the complexity of pipeline connections, increasing the probability of equipment failure and maintenance costs.

[0004] Therefore, in order to comprehensively improve the coverage integrity, drying thoroughness and operating economy of the blower equipment used in automatic car wash production lines, while taking into account the environmental protection requirements of low energy consumption and low noise, it is urgent to optimize the structure and improve the technology of existing equipment to enhance the overall operation quality and market competitiveness of automatic car wash production lines and optimize the end-user experience. Summary of the Invention

[0005] This application aims to address the limitations of existing technologies, where conventional blower equipment used in automatic car wash production lines is structurally restricted, with the blower mechanism only reciprocating in a straight line. This restricts coverage to the top of the vehicle, failing to cover irregularly shaped areas such as the sides and tires, resulting in residual moisture affecting the washing effect and posing a safety hazard in winter. While existing industry solutions involve increasing the number of blowers or boosting power, these methods suffer from high manufacturing costs, high energy consumption, excessive noise, environmental pollution, complex piping, and high costs associated with malfunctions and maintenance. Therefore, this application proposes a blower device for automatic car wash production lines.

[0006] To address the technical problems raised in this application, this application also proposes a blowing method for an automatic car wash production line.

[0007] This application adopts the following solution: This application provides a blower device for an automatic car wash production line, including a support mechanism disposed on a reference surface, a car wash station jointly enclosed by the support mechanism and the reference surface, a first blower mechanism disposed on the support mechanism at the inlet end of the car wash station, a first rotating mechanism disposed between the first blower mechanism and the support mechanism, a second blower mechanism disposed on the support mechanism at the outlet end of the car wash station, and a second rotating mechanism disposed between the second blower mechanism and the support mechanism. The first rotating mechanism is used to drive the first blower mechanism to rotate vertically relative to the support mechanism, and the second rotating mechanism is used to drive the second blower mechanism to rotate horizontally relative to the support mechanism. When a vehicle to be washed enters the car wash station, the first blower mechanism is used to deliver airflow to the top of the vehicle to be washed, and the second blower mechanism is used to deliver airflow to the side of the vehicle to be washed.

The first driving member is used to drive the first rotating assembly to rotate relative to the support mechanism, thereby causing the first connecting seat to rotate relative to the support mechanism. The first blower is disposed on the first connecting seat.

[0009] In some feasible embodiments, the first rotating component includes a first rotating seat disposed on the support mechanism at a position corresponding to the first blowing mechanism, a first rotating hole group disposed on both sides of the first rotating seat and the first connecting seat, and a first rotating shaft that is matched and passes through the first rotating hole group. The first driving member is used to drive the first rotating shaft to rotate relative to the first rotating seat, so as to drive the first connecting seat to rotate relative to the support mechanism.

[0010] In some feasible embodiments, it further includes connecting ears at both ends of the first connecting seat, the first rotating hole group is disposed between the first rotating seat and the connecting ears, and the connecting ears are fixed to one end of the first rotating shaft.

[0011] In some feasible embodiments, a coupling is also provided between the first drive member and the first rotating shaft, one end of the coupling being fixed to the first rotating shaft and the other end being fixed to the output end of the first drive member.

[0012] In some feasible embodiments, the first blower mechanism includes a plurality of first fans disposed on the first connecting seat, and the plurality of first fans can be spaced apart along the length and width directions of the support mechanism.

[0013] In some feasible embodiments, the second rotating mechanism includes a second connecting seat disposed on the support mechanism on both sides of the car wash station outlet, a second driving member disposed on the support mechanism, and a second rotating assembly disposed between the second connecting seat and the support mechanism. The second driving member is used to drive the second connecting seat to rotate relative to the support mechanism through the second rotating assembly.

[0014] In some feasible embodiments, the second rotating component includes a second rotating hole disposed on the support mechanism, and a second rotating shaft disposed on the second connecting seat at a position corresponding to the second rotating hole, the second rotating shaft being matched and disposed within the second rotating hole.

[0015] In some feasible embodiments, the second blower mechanism includes a second fan disposed on the second connecting seat and a flow guide shroud disposed on the second fan. The height of the support mechanism relative to the reference plane is defined as H, and the length of the flow guide shroud is h. The H and the h satisfy the following relationship: 0.4≤h / H≤0.6.

[0016] To address the technical problems raised in this application, this application also provides an automatic car wash blowing method, employing the aforementioned blowing equipment for an automatic car wash production line, comprising the following steps: The conveying parameters of the vehicle to be cleaned are obtained by the speed sensor of the conveyor belt, and the vehicle size parameters are obtained by the grating assembly at the inlet of the car wash station. Based on the acquired conveying parameters and vehicle size parameters, the initial operating parameters of the first and second air blowing mechanisms are determined by matching the preset air blowing parameter database, including air blowing angle, wind speed, rotation speed and running time. Wherein, the initial blowing angle of the first blower mechanism is 15°-20° with the top surface of the vehicle to be washed, and the angle rotation range of the first blower mechanism is 0°-30°; The initial blowing angle of the second blower mechanism is 25°-30° with the side of the vehicle to be washed, and the angle rotation range of the second blower mechanism is 0°-90°.

It includes a support mechanism, a car wash station enclosed by the support mechanism and a reference surface, a first blowing mechanism and a first rotating mechanism located at the inlet end of the support mechanism, and a second blowing mechanism and a second rotating mechanism located at the outlet end of the support mechanism. The first rotating mechanism drives the first blowing mechanism to rotate vertically, and the second rotating mechanism drives the second blowing mechanism to rotate horizontally. When a vehicle enters the car wash station, the first blowing mechanism blows air to the top of the vehicle, and the second blowing mechanism blows air to the sides of the vehicle. This device achieves full coverage blowing of the top and sides of the vehicle through the first and second blowing mechanisms in conjunction with the first and second rotating mechanisms, effectively solving the problem of residual moisture on the vehicle surface; it eliminates the need to excessively increase the number of blowers, significantly reducing manufacturing costs and energy consumption. This application has the advantages of simple structure, effectively improving car wash results and production line efficiency, and ease of promotion and implementation. Attached Figure Description

[0030] Combination Figures 1 to 12 The following description further illustrates the technical solution proposed in this application. This application adopts the following technical solution: a blower device for an automatic car wash production line, comprising a support mechanism X disposed on a reference surface, a car wash station enclosed by the support mechanism X and the reference surface, a first blower mechanism 1 disposed on the support mechanism X at the inlet end of the car wash station, a first rotating mechanism 2 disposed between the first blower mechanism 1 and the support mechanism X, a second blower mechanism 3 disposed on the support mechanism X at the outlet end of the car wash station, and a second rotating mechanism 4 disposed between the second blower mechanism 3 and the support mechanism X. The first rotating mechanism 2 drives the first blower mechanism 1 to rotate vertically relative to the support mechanism X, and the second rotating mechanism 4 drives the second blower mechanism 3 to rotate horizontally relative to the support mechanism X. When a vehicle to be washed enters the car wash station, the first blower mechanism 1 delivers airflow to the top of the vehicle, and the second blower mechanism 3 delivers airflow to the side of the vehicle.

[0031] This application provides a blowing device and method for an automatic car wash production line. It includes a support mechanism, a car wash station enclosed by the support mechanism and a reference surface, a first blowing mechanism and a first rotating mechanism located at the inlet end of the support mechanism, and a second blowing mechanism and a second rotating mechanism located at the outlet end of the support mechanism. The first rotating mechanism drives the first blowing mechanism to rotate vertically, and the second rotating mechanism drives the second blowing mechanism to rotate horizontally. When a vehicle enters the car wash station, the first blowing mechanism blows air towards the top of the vehicle, and the second blowing mechanism blows air towards the sides of the vehicle. This device, through the first and second blowing mechanisms working in conjunction with the first and second rotating mechanisms, achieves full-coverage blowing of the top and sides of the vehicle, effectively solving the problem of residual moisture on the vehicle surface; it eliminates the need to excessively increase the number of blowers, significantly reducing manufacturing costs and energy consumption. This application has the advantages of simple structure, effectively improving car wash results and production line efficiency, and ease of promotion and implementation.

[0032] It should be noted that the terms "exit" and "entry" in this technical solution are not intended to limit the technical solution itself, but are merely auxiliary representations to enhance the clarity of the description.

[0033] In actual implementation, the outlet and inlet of this technical solution can be interchanged according to usage requirements. In this embodiment, the first rotating mechanism 2 includes a first connecting seat 20 disposed on the support mechanism X and located at the top of the car wash station, a first driving member 21 disposed on the support mechanism X, and a first rotating component 22 with one end disposed on the first connecting seat 20 and the other end disposed on the output end of the first driving member 21. The first driving member 21 is used to drive the first rotating component 22 to rotate relative to the support mechanism X, thereby driving the first connecting seat 20 to rotate relative to the support mechanism X. The first blower mechanism 1 is disposed on the first connecting seat 20.

[0034] In actual implementation, the support mechanism X is fixed to a reference surface (such as the floor of a car wash production line), and the two together form a car wash station with specifications adapted to conventional vehicle models, ensuring that vehicles to be washed can enter and leave smoothly. The first blower mechanism 1 is assembled to the top of the car wash station inlet end of the support mechanism X via the first connecting seat 20 of the first rotating mechanism 2. The first drive component 21 and the first rotating component 22 are in the initial standby state. At this time, the air outlet of the first blower mechanism 1 faces the inside of the car wash station, and its initial angle is aligned with the top area of ​​the vehicle's entry direction. The second blower mechanism 3 is assembled to the car wash station outlet end of the support mechanism X via the second rotating mechanism 4. In the initial state, the air outlet faces the inside of the station, aligned with the middle and lower areas of the vehicle's side. At the same time, the equipment establishes signal linkage with the conveyor system (conveyor belt) of the car wash production line to ensure that the blowing action is synchronized with the vehicle's movement rhythm.

[0035] When a vehicle to be washed enters the car wash station driven by the conveyor belt, the grating assembly at the inlet end is triggered, and the grating assembly sends a start signal to the first rotating mechanism 2. The first driving component 21 starts working, driving the first rotating assembly 22 to reciprocate vertically relative to the support mechanism X. During the rotation, the first rotating assembly 22 drives the first connecting seat 20 fixed to it to rotate synchronously, thereby driving the first blower mechanism 1 to achieve vertical angle adjustment (such as rotating from the top area of ​​the vehicle's front windshield to the middle, rear, and top areas of the rear windshield). During this process, the first blower mechanism 1 continuously outputs airflow, which, through vertical angle coverage, blows the residual moisture on the top of the vehicle (including the upper edges of the front and rear windshields) to the sides and rear of the vehicle, completing the initial removal of moisture from the top.

[0036] As the vehicle continues to move to the center of the car wash bay, the first air blower mechanism 1 at the inlet completes full-coverage air blowing and returns to its initial state along with the first rotating mechanism 2; simultaneously, the second rotating mechanism 4 starts. The second drive component drives the second air blower mechanism 3 to reciprocate horizontally, covering the entire height of the vehicle's side (from above the wheels to the side edge of the roof) and the front and rear length (from the front side to the rear side). The second air blower mechanism 3 continuously outputs airflow, blowing the residual moisture on the vehicle's side (including the doors, fenders, and side windows) outwards, while simultaneously replenishing and removing any remaining moisture from the corners that was not completely removed during the top blowing stage.

[0037] When the vehicle has completely driven out of the car wash bay, the exit position sensor sends a stop signal, the second rotating mechanism 4 drives the second blower mechanism 3 to reset to the initial state, and the entire blower system returns to standby state, waiting for the next vehicle to be washed to enter, completing a complete blower cycle.

[0038] In actual implementation, the coordinated design of the vertical rotation of the first air blowing mechanism and the horizontal rotation of the second air blowing mechanism achieves full-area air blowing coverage on the top (including the top of the front and rear windshields) and sides of the vehicle. This avoids the blind spots in traditional fixed air blowing equipment (such as the corners of the roof and the upper and lower edges of the side windows), effectively solving the problem of residual moisture on the vehicle surface, improving the cleanliness of the car wash, and reducing the need for subsequent manual wiping. Furthermore, this solution does not enhance the blowing effect by increasing the number of fans or increasing their power. Instead, it maximizes the coverage of a single air blowing mechanism by optimizing the coordination logic between the first and second rotating mechanisms and the first and second air blowing mechanisms. This significantly reduces equipment manufacturing costs (by reducing the number of core components such as fans) and operating energy consumption (by avoiding the high energy consumption of multiple fans operating simultaneously), meeting the energy conservation and consumption reduction requirements of industrial production.

[0039] In this embodiment, the first rotating component 22 includes a first rotating seat 220 disposed on the support mechanism X at a position corresponding to the first blower mechanism 1, a first rotating hole group 221 disposed on both sides of the first rotating seat 220 and the first connecting seat 20, and a first rotating shaft 222 that is matched and passes through the first rotating hole group 221. The first driving member 21 is used to drive the first rotating shaft 222 to rotate relative to the first rotating seat 220, so as to drive the first connecting seat 20 to rotate relative to the support mechanism X.

[0040] In this embodiment, it also includes connecting ears 23 disposed at both ends of the first connecting seat 20, the first rotating hole group 221 is disposed between the first rotating seat 220 and the connecting ears 23, and the connecting ears 23 are fixed to one end of the first rotating shaft 222.

[0041] In this embodiment, a coupling 24 is also provided between the first driving member 21 and the first rotating shaft 222. One end of the coupling 24 is fixed to the first rotating shaft 222, and the other end is fixed to the output end of the first driving member 21.

[0042] like Figure 2 As shown, in this embodiment, the first blower mechanism 1 includes a plurality of first blowers 10 disposed on the first connecting seat 20, and the plurality of first blowers 10 can be spaced apart along the length and width directions of the support mechanism.

[0043] In actual implementation, multiple first fans 10 are arranged at intervals on the first connecting seat 20 along the length direction (vehicle traffic direction) and width direction (perpendicular to the vehicle traffic direction) of the support mechanism X, forming a matrix-style air blowing layout to improve the uniformity of top air blowing; the first connecting seat 20 is assembled with the first rotating component 22 through the connecting ears 23 at both ends, and the first rotating shaft 222 of the first rotating component 22 passes through the first rotating hole group 221 of the first rotating seat 220 and the connecting ear 23 to achieve a rotatable connection; the first driving component 21 (telescopic cylinder) is fixed to the first rotating shaft 222 through the coupling 24 to ensure accurate power transmission. At this time, the entire first rotating mechanism is in standby state, and the air outlet of the first fan 10 faces the inside of the workstation, with the initial angle aligned with the top area of ​​the windshield in the direction of vehicle entry.

[0044] When a vehicle to be washed enters the car wash station driven by the conveyor belt, the front of the vehicle blocks the grating assembly at the inlet. The grating assembly immediately sends a trigger signal to the control system, which simultaneously starts the first drive component 21 and multiple first fans 10. The first drive component 21 outputs thrust, which is transmitted to the first rotating shaft 222 through the coupling 24. The first rotating shaft 222 rotates smoothly within the first rotating hole group 221 of the first rotating seat 220 and the connecting ear 23, thereby driving the connecting ear 23 and the first connecting seat 20 fixed thereto to reciprocate vertically. During the rotation of the first connecting seat 20, it drives the multiple first fans 10 arranged at intervals on it to adjust their angles synchronously, achieving full coverage of the top area from the top of the windshield to the middle of the roof, the rear of the roof, and the top of the rear windshield. The matrix-style first fans 10 continuously output airflow, and the airflow overlaps to form a uniform blowing surface, efficiently blowing the residual moisture on the top to the sides and rear of the vehicle, avoiding moisture residue caused by uneven blowing from a single fan.

[0045] In this embodiment, the second rotating mechanism 4 includes a second connecting seat 40 disposed on the support mechanism X on both sides of the car wash station outlet, a second driving member 41 disposed on the support mechanism X, and a second rotating assembly 42 disposed between the second connecting seat 40 and the support mechanism X. The second driving member 41 is used to drive the second connecting seat 40 to rotate relative to the support mechanism X through the second rotating assembly 42.

[0046] In this embodiment, the second rotating component 42 includes a second rotating hole 420 disposed on the support mechanism X, and a second rotating shaft 421 disposed on the second connecting seat 40 at a position corresponding to the second rotating hole 420. The second rotating shaft 421 is matched and disposed within the second rotating hole 420.

[0047] In this embodiment, the second blower mechanism 3 includes a second blower 30 disposed on the second connecting seat 40 and a flow guide 31 disposed on the second blower 30. The height of the support mechanism X relative to the reference plane is defined as H, and the length of the flow guide 31 is defined as h. The relationship between H and h is: 0.4≤h / H≤0.6.

[0048] In actual implementation, the value of h / H is 0.5; When the vehicle is located at the exit of the car wash station, the second drive unit 41 drives the second connecting seat 40 to rotate horizontally around the second rotating shaft 421 (embedded in the second rotating hole 420), which drives the second fan and the guide shroud 31 to rotate synchronously, so as to blow air on the side of the vehicle (especially the tire part).

[0049] In actual implementation, the ratio (h / H) of the length h of the fairing to the height H of the support mechanism X relative to the reference plane is 0.4-0.6. This not only adapts to the side height of conventional vehicle models (from sedans to SUVs) but also avoids the situation where the fairing is too long, resulting in increased airflow resistance (increased energy consumption) or too short, resulting in incomplete coverage. There is no need to excessively increase the number of fans. By optimizing the structure and maximizing the blowing efficiency through size matching, the total energy consumption of multiple low-power first fans is lower than that of high-power fans with the same coverage range. The second fan improves the airflow utilization rate with the help of the fairing, further reducing the operating energy consumption.

[0050] To address the technical problems raised in this application, this application also provides an automatic car wash blowing method, employing the aforementioned blowing equipment for an automatic car wash production line, comprising the following steps: The conveying parameters of the vehicle to be cleaned are obtained by the speed sensor of the conveyor belt, and the vehicle size parameters are obtained by the grating assembly at the inlet of the car wash station. Among them, the track conveyor speed range is 0.8m / min-1.2m / min, the detection accuracy is ±0.05m / min, the sampling frequency is 10Hz, the vehicle length detection range is 3.0-5.5m, the vehicle roof height detection range is 1.5-2.2m, the detection accuracy is ±0.03m, and the grating scanning frequency is 50Hz; Based on the acquired conveying parameters and vehicle size parameters, the initial operating parameters of the first and second air blowing mechanisms are determined by matching the preset air blowing parameter database. The initial operating parameters of the first and second air blowing mechanisms include air blowing angle, wind speed, rotation speed and running time. After the vehicle to be washed enters the car wash station, multiple sets of humidity sensors installed in the car wash station detect the humidity value of the vehicle surface (roof and sides of the vehicle). The average value of each set of humidity values ​​is used as the dryness of the vehicle after drying. When the detected dryness reaches the preset dryness threshold (the dryness threshold can be set according to the climate of different regions), the operating parameters of the first and second blower mechanisms are reduced to the preset values. Wherein, the initial blowing angle of the first blower mechanism is 15°-20° with the top surface of the vehicle to be washed, and the angle rotation range of the first blower mechanism is 0°-30°; The initial blowing angle of the second blower mechanism is 25°-30° with the side of the vehicle to be washed, and the angle rotation range of the second blower mechanism is 0°-90°.

[0051] The output wind speed of the first blower mechanism is 18m / s-22m / s, and the rotation speed of the first blower mechanism is 30° / s. The calculation formula for the running time of the first blower mechanism is as follows: Running time = vehicle length ÷ track conveyor speed + 2s (and running time ≥ 30s), where 2s is the buffer time for the vehicle to be washed to enter the car wash station.

[0052] The output wind speed of the second blower mechanism is 22m / s-26m / s, and the rotation speed of the second blower mechanism is 60° / s. The calculation formula for the running time of the second blower mechanism is as follows: Running time = vehicle length ÷ track conveyor speed + 3s (and running time ≥ 40s), where 3s is the tire drying buffer time.

[0053] The humidity sensor has a detection range of 0%RH-100%RH and a detection accuracy of ±2%RH. The humidity sensor sampling points are distributed as follows: 2 on the roof, 2 on the left side of the vehicle, 2 on the right side of the vehicle, 1 at the front of the vehicle, and 1 at the rear of the vehicle, for a total of 8 sampling points.

[0054] Furthermore, the humidity sensor, the first rotating mechanism, the first blowing mechanism, the second rotating mechanism, the second blowing mechanism, and the conveying mechanism are all connected to the industrial control system (such as a host computer, a dedicated controller, etc.) via signal connection.

[0055] In actual implementation, a nickel-chromium alloy heating wire assembly is added inside the air outlet of the first and second fans. The nickel-chromium alloy heating wire assembly is connected to the temperature sensor on the support mechanism. When the temperature value sensed by the temperature sensor is lower than 5℃, the nickel-chromium alloy heating wire assembly starts the heating function. The heating temperature is controlled between 30℃ and 50℃ (this temperature range will not damage the car paint), which improves the drying efficiency in low temperature environment and can also realize the defrosting function of the car body surface. Furthermore, a metal protective mesh is provided on the outside of the nickel-chromium alloy heating wire to prevent foreign objects from contacting the heating wire and causing damage. The protective mesh also serves as a guide to improve airflow stability.

[0056] This application provides a blowing device and method for an automatic car wash production line. It includes a support mechanism, a car wash station enclosed by the support mechanism and a reference surface, a first blowing mechanism and a first rotating mechanism located at the inlet end of the support mechanism, and a second blowing mechanism and a second rotating mechanism located at the outlet end of the support mechanism. The first rotating mechanism drives the first blowing mechanism to rotate vertically, and the second rotating mechanism drives the second blowing mechanism to rotate horizontally. When a vehicle enters the car wash station, the first blowing mechanism blows air to the top of the vehicle, and the second blowing mechanism blows air to the sides of the vehicle. This device achieves full coverage blowing of the top and sides of the vehicle through the first and second blowing mechanisms in conjunction with the first and second rotating mechanisms, effectively solving the problem of residual moisture on the vehicle surface; it eliminates the need to excessively increase the number of blowers, significantly reducing manufacturing costs and energy consumption. This application has the advantages of simple structure, effectively improving car wash results and production line efficiency, and ease of promotion and implementation.
