Technical Field
[0001] This utility model relates to the field of production and processing technology, and in particular to a spraying device for processing track plates. Background Technology
[0002] Spraying is a crucial step in the processing of track plates, aiming to provide a protective coating to enhance their wear resistance, corrosion resistance, and other properties. Traditional spraying equipment suffers from several problems in practical use. For example, the spray gun angle is typically fixed, making it difficult to flexibly adapt to the complex shape of the track plates and the spraying needs of different areas. This results in uneven spraying, with some areas failing to be effectively coated, severely impacting the coating quality and protective effect of the track plates. Furthermore, replacing the spray nozzles in existing equipment is cumbersome, consuming significant time and manpower. Frequent replacements when nozzles wear out or become clogged greatly reduce production efficiency and increase production costs.
[0003] Chinese patent application CN202222963459.4 discloses a spraying device for processing track plates. The key technical points of the device are: a feed pump is started, which sucks in paint through the feed pipe and delivers it to the discharge pipe. Finally, the paint is sprayed out through multiple spray nozzles to spray the track plates. The multiple spray nozzles work together to improve the efficiency and quality of the spraying operation. The spraying mechanism is a movable structure, which can be connected to different spraying boxes according to the usage requirements, thus improving the compatibility of the device. Multiple casters are used to move the spraying mechanism, which is convenient for moving and transporting, thus improving the portability and flexibility of the spraying mechanism during use.
[0004] Regarding the above-mentioned and existing related technologies, the inventors believe that the following defects often exist: the angle of the spray bar is usually fixed, which makes it difficult to flexibly adapt to the complex shape of the track plate and the spraying requirements of different parts, resulting in uneven spraying and some areas that cannot be effectively sprayed, which seriously affects the spraying quality and protective effect of the track plate; therefore, a spraying device for track plate processing is proposed to address the above problems. Utility Model Content
[0005] The purpose of this invention is to address the shortcomings of existing technologies, such as uneven coating and ineffective coating in certain areas due to the complex shape of track plates and the different coating requirements of different parts. Therefore, this invention proposes a coating device for track plate processing.
[0006] To achieve the above objectives, the present invention adopts the following technical solution: a spraying device for processing track plates, comprising a spray box body, a spraying rod mounted on the surface of the spray box body, a plurality of spray nozzles mounted on the surface of the spraying rod, adjustment devices provided on both sides of the spray box body, each adjustment device comprising two connecting rods, both connecting rods being rotatably connected to both sides of the spray box body, the ends of the two connecting rods being fixedly connected to the spraying rod at their closest points, a single-hole plate being fixedly connected to the arc surface of the connecting rod, an insert rod being slidably inserted into the single-hole plate, arc-shaped grooves being formed on both sides of the spray box body, a plurality of circular grooves being formed on the surface of the arc-shaped grooves of the spray box body, and a circular plate being fixedly connected to one end of the insert rod.
[0007] The aforementioned components achieve the following effect: by setting up an adjustment device, the angle of the paint spray bar can be flexibly adjusted, thereby adjusting the direction of the nozzle and the spraying angle. This avoids the situation where the track plates have complex shapes and different surfaces and angles. If the angle of the paint spray bar is fixed and not adjusted, the paint mist sprayed from the nozzle cannot evenly cover all parts of the track plates. This may result in some areas having an excessively thick paint layer, while other areas have an excessively thin paint layer or even no paint at all, affecting the appearance and protective performance of the track plates. This improves the practicality of the device.
[0008] Preferably, the arc surface of the insertion rod is fitted with a spring, and the two ends of the spring are fixedly connected to the circular plate and the single-hole plate, respectively.
[0009] The effects achieved by the above components are as follows: they improve the stability of the insert rod, realize the automatic positioning of the insert rod after the angle of the spray gun is adjusted, effectively improve the stability of the insert rod fixed in the circular groove of the spray gun body, ensure that the spray gun can be firmly maintained at the adjusted angle, and thus ensure that the nozzle performs spraying operations at a stable angle, thereby improving the ease of use of the device and the spraying effect.
[0010] Preferably, the arc surface of the insertion rod is fixedly connected to a limiting plate, and the limiting plate is slidably connected to the surface of the paint spray box body.
[0011] The effects achieved by the above components are as follows: they prevent spring damage, avoid damage due to excessive stretching, limit the movement of the insertion rod by the limiting plate, ensure that the spring always works within a reasonable elastic deformation range, extend the service life of the spring, reduce the frequency and cost of equipment maintenance due to spring damage, ensure the continuous and stable operation of the device's adjustment function, and improve the reliability and durability of the entire device.
[0012] Preferably, a fixing rod is fixedly connected to the inner surface of the limiting plate, an L-shaped plate is rotatably connected to the arc surface of the fixing rod, and a square rod is fixedly connected to the surface of the single-hole plate.
[0013] The aforementioned components achieve the following effect: they restrict the movement of the insert rod, preventing it from shifting due to external forces when the operator adjusts the angle of the spray gun. If the angle of the spray gun is not properly adjusted, the insert rod may be inserted into the incorrect groove of the spray gun body, requiring the operator to manually pull the insert rod, thus increasing the operator's workload.
[0014] Preferably, the surface of the paint spray bar is provided with a plurality of replacement devices, the plurality of replacement devices including a plurality of fixed chambers, the plurality of fixed chambers being fixedly connected to the surface of the paint spray bar, an operating plate being slidably connected to the inner surface of the fixed chamber, a plurality of rotating rings being rotatably connected to the surface of the paint spray bar, the surface of the rotating rings being provided with square grooves, and a long rod being fixedly connected to the surface of the spray nozzle, the arc surface of the long rod being slidably connected to the rotating rings.
[0015] The effects achieved by the above-mentioned components are as follows: by setting up a replacement device, the nozzle can be easily disassembled and installed from inside the rotating ring, which greatly shortens the nozzle replacement time, improves the maintenance efficiency of the equipment, and can be quickly replaced when the nozzle has problems such as wear or blockage, ensuring the continuity of the spraying operation, avoiding production stoppage caused by nozzle failure, and effectively improving the overall practicality and production efficiency of the equipment.
[0016] Preferably, the surface of the paint spray bar is fitted with several torsion springs, one end of which is fixedly connected to the rotating ring.
[0017] The aforementioned components achieve the following effect: they automatically rotate the rotating ring. This automatic rotation design not only reduces manual operation steps and labor intensity, but also improves the efficiency and smoothness of nozzle replacement, further ensuring the efficient operation of the device in the nozzle maintenance process and enhancing the ease of use and practicality of the equipment.
[0018] Preferably, a friction pad is fixedly connected to the surface of the rotating ring, and the surface of the friction pad is provided with anti-slip protrusions.
[0019] The above-mentioned components achieve the following effects: they increase the friction of the rotating ring. The anti-slip protrusions of the friction pad effectively increase the friction between the operator's hand and the rotating ring, making the rotation operation more stable and controllable. This avoids deviations in the rotation angle due to hand slippage, ensuring that the rotating ring can rotate precisely to the appropriate angle so that the subsequent operation plate can smoothly fit into the square groove of the rotating ring, completing the installation and fixing of the nozzle.
[0020] In summary, the beneficial effects of this utility model are as follows:
[0021] 1. In this utility model, by setting an adjustment device, the angle of the paint spray bar can be flexibly adjusted, thereby adjusting the direction of the nozzle and the spraying angle. This avoids the situation where the track plate has a complex shape and different surfaces and angles. If the angle of the paint spray bar is fixed and not adjusted, the paint mist sprayed from the nozzle cannot evenly cover all parts of the track plate. This may result in some areas having an excessively thick paint layer, while other areas have an excessively thin paint layer or even no paint at all, affecting the appearance and protective performance of the track plate. This improves the practicality of the device.
[0022] 2. In this utility model, by setting a replacement device, the nozzle can be easily disassembled and installed from inside the rotating ring, which greatly shortens the nozzle replacement time, improves the maintenance efficiency of the equipment, and can be quickly replaced when the nozzle has problems such as wear or blockage, ensuring the continuity of the spraying operation and avoiding production stoppage caused by nozzle failure, thus effectively improving the overall practicality and production efficiency of the device.

Detailed Implementation
[0029] Reference Figure 1As shown, this utility model provides a technical solution: a spraying device for processing track plates, including a spray box body 1, a spray rod 5 mounted on the surface of the spray box body 1, a plurality of nozzles 2 mounted on the surface of the spray rod 5, and adjustment devices 3 on both sides of the spray box body 1. By setting the adjustment devices 3, the angle of the spray rod 5 can be flexibly adjusted, thereby adjusting the orientation and spraying angle of the nozzles 2. This avoids the situation where the track plate has a complex shape and different surfaces and angles. If the angle of the spray rod 5 is fixed and not adjusted, the paint mist sprayed by the nozzles 2 cannot evenly cover all parts of the track plate, which may lead to some areas being covered unevenly. In some areas, the paint layer is too thick, while in others it is too thin or not sprayed at all, affecting the appearance and protective performance of the track plates. To improve the practicality of the device, the surface of the spray bar 5 is equipped with several replacement devices 4. By setting the replacement devices 4, the spray head 2 can be easily disassembled and installed from the rotating ring 41, which greatly shortens the replacement time of the spray head 2 and improves the maintenance efficiency of the equipment. When the spray head 2 has problems such as wear or blockage, it can be quickly replaced, ensuring the continuity of the spraying operation and avoiding production stoppages caused by the failure of the spray head 2. This effectively improves the overall practicality and production efficiency of the device.
[0030] The specific settings and functions of the adjustment device 3 and the replacement device 4 will be explained in detail below.
[0031] Reference Figure 2 and Figure 3As shown in this embodiment: the two adjusting devices 3 include two connecting rods 31, both of which are rotatably connected to both sides of the paint spray box body 1. The ends of the two connecting rods 31 that are close to each other are fixedly connected to the paint spray bar 5. A single-hole plate 32 is fixedly connected to the arc surface of the connecting rod 31. A plug rod 33 is slidably inserted into the single-hole plate 32. Arc grooves are opened on both sides of the paint spray box body 1. Several circular grooves are opened on the surface of the arc grooves of the paint spray box body 1. A circular plate 34 is fixedly connected to one end of the plug rod 33. A spring 35 is sleeved on the arc surface of the plug rod 33. The two ends of the spring 35 are fixedly connected to the circular plate 34 and the single-hole plate 32, respectively. When the operator needs to adjust the angle of the spray head 2, the operator first pulls the circular plate 34 to drive the plug rod 33 in the single-hole plate 32. The plate 32 slides within the spray gun 33, at which point the spring 35 is stretched until the arc surface of the insertion rod 33 is completely separated from the surface of the circular groove in the spray gun body 1. Then, the operator can rotate the single-hole plate 32 to rotate the connecting rod 31 within the spray gun body 1. The connecting rod 31 rotates the spray gun 5, and the single-hole plate 32 moves the insertion rod 33. When the spray gun 5 rotates to a certain angle, the operator can release the circular plate 34. The spring 35's rebound force moves the circular plate 34, which in turn moves the insertion rod 33 within the single-hole plate 32 until it is inserted into the circular groove in the spray gun body 1. This improves the stability of the insertion rod 33 and achieves automatic positioning of the insertion rod 33 after the spray gun 5 angle is adjusted, effectively improving the fixation of the insertion rod 33 within the spray gun body 1. The stability within the circular groove of the spray box body 1 ensures that the spray bar 5 can be stably maintained at the adjusted angle, thereby ensuring that the nozzle 2 performs spraying operations at a stable angle, improving the ease of use and spraying effect of the device. The arc surface of the insertion rod 33 is fixedly connected to the limiting plate 36, which is slidably connected to the surface of the spray box body 1. When the operator needs to adjust the angle of the spray bar 5, the operator first pulls the insertion rod 33 to slide within the single-hole plate 32. The insertion rod 33 drives the limiting plate 36 to move until the surface of the limiting plate 36 is in contact with the single-hole plate 32, and the arc surface of the insertion rod 33 is completely separated from the circular groove of the spray box body 1. At this point, the effect of preventing damage to the spring 35 is achieved, avoiding damage to the spring 35 due to excessive stretching. The limiting plate 36 restricts... The travel distance of the insertion rod 33 is controlled to ensure that the spring 35 always operates within a reasonable elastic deformation range, extending the service life of the spring 35, reducing the frequency and cost of equipment maintenance due to spring 35 damage, ensuring the continuous and stable operation of the device's adjustment function, and improving the reliability and durability of the entire device. A fixing rod 37 is fixedly connected to the inner surface of the limiting plate 36, and an L-shaped plate 38 is rotatably connected to the arc surface of the fixing rod 37. A square rod 39 is fixedly connected to the surface of the single-hole plate 32. When the operator needs to adjust the angle of the paint spraying rod 5, the operator first pulls the insertion rod 33 to slide within the single-hole plate 32. The insertion rod 33 drives the limiting plate 36 to move, and the limiting plate 36 drives the L-shaped plate 38 to move. When the insertion rod 33 moves a certain distance...The operator can rotate the L-shaped plate 38 around the arc surface of the fixed rod 37 until the surface of the L-shaped plate 38 is in contact with the square rod 39. This restricts the movement of the insertion rod 33, preventing it from shifting due to external force when adjusting the angle of the paint spraying rod 5. If the angle of the paint spraying rod 5 is not properly adjusted, the insertion rod 33 may be inserted into the incorrect groove of the paint spraying box body 1, requiring the operator to manually pull the insertion rod 33, thus increasing their workload.
[0032] Reference Figure 4 and Figure 5 As shown, specifically, the several replacement devices 4 include several fixed chambers 42, each fixedly connected to the surface of the spray gun 5. An operating plate 43 is slidably connected to the inner surface of each fixed chamber 42. Several rotating rings 41 are rotatably connected to the surface of the spray gun 5, and square grooves are formed on the surface of each rotating ring 41. A long rod 45 is fixedly connected to the surface of the nozzle 2, and the arc surface of the long rod 45 is slidably connected to the rotating rings 41. Several torsion springs 44 are fitted onto the surface of the spray gun 5, and one end of each torsion spring 44 is fixedly connected to the rotating ring 41. When the operator needs to replace the nozzle... When changing nozzle 2, the operator first pulls the control plate 43 and slides it across the surface of the square groove in the rotating ring 41 until the control plate 43 is completely separated from the surface of the square groove in the rotating ring 41. At this time, the torque of the torsion spring 44 drives the rotating ring 41 to rotate, and the long rod 45 slides inside the rotating ring 41. Then, the operator can pull the nozzle 2 to drive the long rod 45 to slide inside the rotating ring 41 until the nozzle 2 is completely separated from the paint spray bar 5. This achieves the effect of automatically rotating the rotating ring 41. The automatic rotation design not only reduces manual operation steps but also reduces labor intensity. It also improves the efficiency and smoothness of nozzle 2 replacement, further ensuring the efficient operation of the device in the nozzle 2 maintenance process, and enhancing the ease of use and practicality of the equipment. A friction pad 46 is fixedly connected to the surface of the rotating ring 41. The surface of the friction pad 46 is provided with anti-slip protrusions. When the operator needs to install the nozzle 2, the operator first pushes the nozzle 2 to drive the long rod 45 to slide inside the rotating ring 41. When the arc surface of the long rod 45 is completely in contact with the rotating ring 41, the operator rotates the friction pad 46 to drive the rotating ring 41 to rotate. When the rotating ring 41 rotates to a certain angle... After that, the operator pushes the control plate 43 to slide within the fixed chamber 42 until the control plate 43 is in contact with the surface of the square groove of the rotating ring 41. At this point, the friction of the rotating ring 41 is increased. The anti-slip protrusions of the friction pad 46 effectively increase the friction between the operator's hand and the rotating ring 41, making the rotation operation more stable and controllable. This avoids deviation in the rotation angle due to hand slippage, ensuring that the rotating ring 41 can be accurately rotated to the appropriate angle so that the control plate 43 can be smoothly attached to the square groove of the rotating ring 41, thus completing the installation and fixing of the nozzle 2.
[0033] Working principle: When the operator needs to adjust the angle of the spray nozzle 2, the operator first pulls the circular plate 34, causing the insertion rod 33 to slide within the single-hole plate 32. The insertion rod 33 moves the limiting plate 36, which in turn moves the L-shaped plate 38. After the insertion rod 33 has moved a certain distance, the operator can rotate the L-shaped plate 38 on the arc surface of the fixed rod 37 until the surface of the L-shaped plate 38 is in contact with the square rod 39, and the surface of the limiting plate 36 is in contact with the single-hole plate 32. At this time, the spring 35 is stretched, and the arc surface of the insertion rod 33 is completely separated from the surface of the circular groove of the paint spray box body 1. Then, the operator can rotate the single-hole plate 32, causing the connecting rod 31 to rotate within the paint spray box body 1. The connecting rod 31 then rotates the spray nozzle 5, and the single-hole plate 32 moves the insertion rod 38. When the spray bar 5 rotates to a certain angle, the operator can release the circular plate 34. At this time, the rebound force of the spring 35 drives the circular plate 34 to move. The circular plate 34 drives the insertion rod 33 to slide in the single-hole plate 32 until the insertion rod 33 is inserted into the circular groove of the spray box body 1. This achieves the effect of flexibly adjusting the angle of the spray bar 5, thereby adjusting the orientation of the nozzle 2 and the spraying angle. This avoids the situation where the track plate has a complex shape and different surfaces and angles. If the angle of the spray bar 5 is fixed and not adjusted, the paint mist sprayed by the nozzle 2 cannot evenly cover all parts of the track plate. This may result in some areas having an excessively thick paint layer, while other areas have an excessively thin paint layer or even no paint at all, affecting the appearance and protective performance of the track plate. This improves the practicality of the device.
[0034] When the operator needs to replace nozzle 2, firstly, the operator pulls the control plate 43 and slides it across the surface of the square groove of the rotating ring 41 until the control plate 43 is completely separated from the surface of the square groove of the rotating ring 41. At this time, the torque of the torsion spring 44 drives the rotating ring 41 to rotate, and the long rod 45 slides within the rotating ring 41. Then, the operator can pull the nozzle 2 to drive the long rod 45 to slide within the rotating ring 41 until the nozzle 2 is completely separated from the paint spray bar 5. When the operator needs to install nozzle 2, firstly, the operator pushes the nozzle 2 to drive the long rod 45 to slide within the rotating ring 41 until the arc surface of the long rod 45 is completely in contact with the rotating ring 41. When the friction pad 46 is rotated, the rotating ring 41 rotates. When the rotating ring 41 rotates to a certain angle, the operator pushes the operating plate 43 to slide in the fixed chamber 42 until the operating plate 43 is in contact with the surface of the square groove of the rotating ring 41. This allows the nozzle 2 to be easily disassembled and installed from inside the rotating ring 41, greatly shortening the nozzle 2 replacement time and improving the equipment maintenance efficiency. When the nozzle 2 experiences wear or blockage, it can be quickly replaced, ensuring the continuity of the spraying operation and avoiding production stoppages caused by nozzle 2 failures. This effectively improves the overall practicality and production efficiency of the device.
