[0020] an anti-sway member, which is slidably arranged on the frame and located on one side of the lifting frame. There are two anti-sway members, which are respectively arranged on both sides of the transfer member. After the two anti-sway members slide, they approach or move away from each other, and after sliding, the anti-sway members abut against the side wall of the workpiece to be sprayed to limit the movement of the workpiece to be sprayed.

[0031] The working principle and beneficial effects of the present utility model are as follows:

[0032] In the present utility model, the lifting frame constitutes the main support structure of the entire device. It is stable and height-adjustable, capable of adapting to sprayed parts of different sizes and spraying scenarios. The spray gun fixing member moves up and down on the lifting frame, and realizes precise vertical movement through the way of guide rail and lead screw transmission, so that the height position of the spray gun can be flexibly adjusted. The spray gun rotating member is installed on the spray gun fixing member and can rotate freely. This enables the spray gun to change the spraying angle in the horizontal direction to adapt to the spraying requirements of different parts of the sprayed part. The spray gun is slidably arranged relative to the spray gun rotating member. When the speed of the sprayed part changes during movement or the equipment fails and cannot be stopped in time, the spray gun slides relative to the spray gun rotating member under the action of the safety device to ensure that the spray gun and the sprayed part will not collide.

[0033] The spraying device for large cross-section workpieces has significant advantages compared with the prior art. Through the coordinated cooperation of the lifting frame, the spray gun fixing part, the spray gun rotating part and the slidable spray gun, it greatly improves the flexibility and adaptability of spraying, can comprehensively and multi-angularly cope with the complex shapes and sizes of large cross-section workpieces to be sprayed, and ensures the uniformity and integrity of the coating. At the same time, the precise control method guarantees the spraying accuracy and quality, can accurately align each part of the workpiece to be sprayed, and avoids omission and unevenness. In addition, the automated adjustment also improves the work efficiency, reduces manual intervention, shortens the spraying time, and reduces the labor intensity of the operator, providing a reliable guarantee for the high-quality spraying of large cross-section workpieces to be sprayed. When facing large cross-section workpieces to be sprayed, traditional spraying devices often have problems with inflexible adjustment of spraying angles and positions, resulting in difficult uniform spraying of some parts of the workpiece to be sprayed and affecting the coating quality. In this device, the spray gun fixing part can be flexibly lifted on the lifting frame, the spray gun rotating part can rotate freely, and the spray gun can also slide relatively, so that the large cross-section workpiece to be sprayed can be sprayed comprehensively and without dead angles, ensuring the uniformity and integrity of the coating. In the prior art, for the spraying of large cross-section workpieces to be sprayed, it may be necessary to adjust the position of the workpiece to be sprayed multiple times or use multiple devices to work together, with complex operations and low efficiency. Through the integrated design, this device can complete multi-angular spraying operations at one station, greatly improving the work efficiency and reducing the production time and cost. When traditional spraying devices deal with large cross-section workpieces to be sprayed with different shapes and sizes, they often need complex equipment transformation and debugging. The flexible and adjustable structure of this device can quickly adapt to various workpieces to be sprayed without large-scale equipment modification, enhancing the versatility and practicability of the equipment. In addition, in terms of spraying accuracy and quality control, it is difficult for the prior art to precisely control the distance and angle between the spray gun and the workpiece to be sprayed, and it is easy to have the situation of too thick or too thin coating. This device can achieve precise adjustment of the position and angle of the spray gun through precise lifting, rotation and sliding control, improving the spraying accuracy and quality. The spraying device for large cross-section workpieces is superior to the prior art in terms of spraying effect, work efficiency, versatility and precision control, and can better meet the spraying requirements of large cross-section workpieces to be sprayed.

[0044] Embodiment 1

[0045] Refer to Figures 1 to 2, which is the first embodiment of the present utility model, provides a spraying device for large cross-section workpieces, including a lifting frame 1, a spray gun fixing member 2 is arranged on the lifting frame 1 in a lifting manner, a spray gun rotating member 3 is arranged on the spray gun fixing member 2 in a rotating manner, and a spray gun 4 is arranged on the spray gun rotating member 3 in a sliding manner.

[0046] In this embodiment, the lifting frame 1 constitutes the main support structure of the entire device. It is stable and its height is adjustable, capable of adapting to workpieces to be sprayed with different sizes and spraying scenarios. The spray gun fixing member 2 moves up and down on the lifting frame 1, and realizes precise up and down movement through the way of guide rail and lead screw transmission, so as to flexibly adjust the height position of the spray gun 4. The spray gun rotating member 3 is installed on the spray gun fixing member 2 and can rotate freely. This enables the spray gun 4 to change the spraying angle in the horizontal direction to meet the spraying requirements of different parts of the workpiece to be sprayed. The spray gun 4 is arranged on the spray gun rotating member 3 in a sliding manner. When the speed of the workpiece to be sprayed changes during movement or the equipment fails and cannot be stopped in time, the spray gun 4 slides relative to the spray gun rotating member 3 under the action of the safety device to ensure that the spray gun 4 and the workpiece to be sprayed will not collide.

[0047] The large-section workpiece spraying device has significant advantages over the existing technology. It greatly improves the flexibility and adaptability of spraying through the coordinated cooperation of the lifting frame 1, the spray gun fixing part 2, the spray gun rotating part 3 and the slidable spray gun 4, and can cope with the complex shapes and sizes of large-section sprayed parts in all directions and at multiple angles to ensure uniform and complete coating. At the same time, the precise control method ensures the accuracy and quality of spraying, and can accurately align various parts of the sprayed parts to avoid omissions and unevenness. In addition, the automated adjustment also improves work efficiency, reduces manual intervention, shortens the spraying time, and reduces the labor intensity of operators, providing reliable guarantees for high-quality spraying of large-section sprayed parts. When facing large-section sprayed parts, traditional spraying devices often have problems with inflexible adjustment of spraying angles and positions, which makes it difficult for certain parts of the sprayed parts to be sprayed evenly, affecting the coating quality. The spray gun fixing part 2 in the present device can be flexibly raised and lowered on the lifting frame 1, the spray gun rotating part 3 can rotate freely, and the spray gun 4 can also slide relatively, so that the large-section sprayed parts can be sprayed in all directions and without dead angles, ensuring the uniformity and integrity of the coating. In the prior art, the spraying of large-section sprayed parts may require multiple adjustments to the position of the sprayed parts or the use of multiple devices to work together, which is complicated and inefficient. Through an integrated design, the present device can complete multi-angle spraying operations at one station, greatly improving work efficiency and reducing production time and cost. Traditional spraying devices often require complex equipment modification and debugging when dealing with large-section sprayed parts of different shapes and sizes. The flexible and adjustable structure of the present device can quickly adapt to various sprayed parts without large-scale equipment changes, which enhances the versatility and practicality of the equipment. In addition, in terms of spraying accuracy and quality control, it is difficult for the prior art to accurately control the distance and angle between the spray gun 4 and the sprayed parts, and it is easy to have too thick or too thin coatings. This device can achieve precise adjustment of the position and angle of the spray gun 4 through precise lifting, rotation and sliding control, thereby improving the accuracy and quality of spraying. The large-section workpiece spraying device is superior to the existing technology in terms of spraying effect, work efficiency, versatility and precision control, and can better meet the spraying needs of large-section sprayed parts.

[0048] Example 2

[0049] Reference Figures 3 to 4 , which is the second embodiment of the utility model, and this embodiment is different from the first embodiment in that:

[0050] Compared with Example 1, it further includes a fixed seat 5, which is arranged on the spray gun rotating member 3, and the fixed seat 5 has a slide groove 501, and the slide groove 501 has an outlet 502. The clamping member 6 is slidably arranged in the slide groove 501, and the spray gun 4 is arranged on the clamping member 6. After the clamping member 6 slides, it slides out from the outlet 502.

[0051] In this embodiment, in the spraying device for large cross-section workpieces, the fixing seat 5 is installed on the spray gun rotating part 3. The fixing seat 5 is provided with a specific chute 501 which has an outlet 502. The clamping part 6 can slide smoothly within the chute 501. The spray gun 4 is installed on the clamping part 6. When it is necessary to maintain, replace or adjust the position of the spray gun 4, slide the clamping part 6 to move it along the chute 501 and finally slide out from the outlet 502. During the actual spraying process, if it is found that the spray gun 4 fails or a different type of spray gun 4 needs to be replaced, the operator can easily operate the clamping part 6 to move the spray gun 4 out, perform corresponding processing and then install it back. When the speed of the workpiece being sprayed changes during movement or the equipment fails and cannot be stopped in time, the clamping part 6 detaches from the fixing seat 5, causing the spray gun 4 to detach from the spraying position to avoid damage to the spray gun 4. This facilitates the maintenance and replacement operations of the spray gun 4. By sliding the clamping part 6 within the chute 501, the spray gun 4 can be taken out quickly and conveniently, saving operation time and improving work efficiency. Different specifications or performance spray guns 4 can be flexibly replaced according to different spraying requirements to achieve the best spraying effect, enhancing the flexibility and expandability of the device. When the spray gun 4 has problems, it can be quickly replaced, reducing production interruptions caused by equipment failures.

[0052] Furthermore, it further includes a collision prevention part 7. The collision prevention part 7 is arranged on the spray gun 4. The collision prevention part 7 has a contact head 701. The contact head 701 is located on the side of the spray gun 4 nozzle away from the clamping part 6. One end of the elastic part 702 acts on the fixing seat 5 and the other end acts on the clamping part 6, providing a force for the clamping part 6 to move away from the outlet 502.

[0053] In this embodiment, in the spraying device for large cross-section workpieces, the collision prevention part 7 is installed on the spray gun 4. The contact head 701 of the collision prevention part 7 is located on the side of the spray gun 4 nozzle away from the clamping part 6. At the same time, one end of the elastic part 702 acts on the fixing seat 5 and the other end acts on the clamping part 6. During normal spraying operations, the elastic part 702 is in a stretched state, applying a force to the clamping part 6 to move away from the outlet 502, keeping the clamping part 6 in the normal working position. During the spraying process, if the spray gun 4 accidentally collides with other objects, first the contact head 701 of the collision prevention part 7 will contact the collision object, playing a preliminary buffering and protecting role. Then it drives the clamping part 6 to move towards the outlet 502 side. When the moving distance of the collision object is too large, the clamping part 6 slides out from the outlet 502. The collision prevention part 7 can effectively protect the spray gun 4 nozzle from collision damage, reducing equipment repair costs and production delays caused by accidental collisions. The force provided by the elastic part 702 enables the clamping part 6 to be stable in the working position without external force, ensuring the normal working state of the spray gun 4. At the same time, when being collided, the compression of the elastic part 702 can absorb part of the impact force, playing a buffering role and reducing the impact of the collision on the equipment. This design improves the stability and reliability of the equipment and extends the service life of the spray gun 4 and the entire spraying device.

[0054] Further, both ends of the elastic member 702 are provided with clamping members 703, and both the fixed seat 5 and the clamping member 6 are provided with clamping grooves 8 for accommodating the clamping members 703.

[0055] In this embodiment, in the large cross-section workpiece spraying device, both ends of the elastic member 702 are equipped with clamping members 703. At the same time, corresponding clamping grooves 8 are respectively provided on the fixed seat 5 and the clamping member 6. When installing the elastic member 702, the clamping member 703 at one end of the elastic member 702 is embedded into the clamping groove 8 of the fixed seat 5, and the clamping member 703 at the other end is embedded into the clamping groove 8 of the clamping member 6. During the operation of the device, the elastic member 702 needs to be replaced or adjusted. Due to the design of the clamping member 703 and the clamping groove 8, the operation becomes simple and fast. The cooperation between the clamping member and the clamping groove 8 ensures the position stability of the elastic member 702 during the working process, prevents the elastic member 702 from falling off or shifting, and ensures its normal elastic force function. This detachable connection method facilitates the installation, replacement, and maintenance of the elastic member 702, reduces the maintenance difficulty and cost of the device, improves the overall reliability of the device, and reduces the possible failures caused by the insecure connection of the elastic member 702.

[0056] Further, it further includes a frame 10. The lifting frame 1 is arranged on the frame 10. The transfer member 11 is movably arranged on the frame 10 and is located above the lifting frame 1 for transferring the workpiece to be sprayed. The anti-vibration member 9 is slidably arranged on the frame 10 and is located on one side of the lifting frame 1. There are two anti-vibration members 9, which are respectively arranged on both sides of the transfer member 11. The two anti-vibration members 9 move closer to or away from each other after sliding, and the anti-vibration member 9 abuts against the side wall of the workpiece to be sprayed after sliding, for restricting the movement of the workpiece to be sprayed.

[0057] In this embodiment, in the large cross-section workpiece spraying device, the lifting frame 1 is installed on the frame 10. The transfer member 11 can move on the frame 10 and is located above the lifting frame 1 for transferring the workpiece to be sprayed. The anti-vibration member 9 is slidably arranged on the frame 10 and is located on one side of the lifting frame 1. The two anti-vibration members 9 are respectively arranged on both sides of the transfer member 11. When the workpiece to be sprayed is placed on the transfer member 11 for transfer, the two anti-vibration members 9 slide closer to or away from each other according to the size of the workpiece to be sprayed until they abut against the side wall of the workpiece to be sprayed. When encountering bumps or acceleration during the transfer process, the anti-vibration member 9 can effectively restrict the shaking of the workpiece to be sprayed, ensuring the stability of the workpiece to be sprayed during the transfer process, reducing the collision and damage caused by shaking, ensuring the quality of the workpiece to be sprayed, improving the safety of the transfer, and reducing the possibility of accidents. The adjustable anti-vibration member 9 can adapt to workpieces to be sprayed of different sizes, increasing the versatility of the device. The coordinated action of the frame 10, the transfer member 11, and the anti-vibration member 9 provides stable, safe, and universal guarantees for the transfer and spraying of large cross-section workpieces to be sprayed.

[0058] Further, the anti-vibration member 9 includes a sliding seat 901 which is slidably arranged on the frame 10. The sliding seats 901 approach or move away from each other after sliding. A rotating wheel 902 is rotatably arranged relative to the frame 10. A first rotation driving member 903 is arranged on the sliding seat 901. The first rotation driving member 903 drives the rotating wheel 902 to rotate. The rotating wheel 902 is in contact with the workpiece to be sprayed.

[0059] In this embodiment, in the large cross-section workpiece spraying device, the sliding seat 901 can slide on the frame 10 to realize the movement of approaching or moving away from each other. The rotating wheel 902 is rotatably arranged relative to the frame 10. The first rotation driving member 903 is installed on the sliding seat 901 and can drive the rotating wheel 902 to rotate. During operation, the sliding seat 901 slides to adjust the position according to the width of the workpiece to be sprayed. When the position is determined, the first rotation driving member 903 is started to drive the rotating wheel 902 to rotate. The workpiece to be sprayed has a small displacement during the transfer process and contacts the rotating rotating wheel 902. The rotation of the rotating wheel 902 can play a role in buffering and guiding, further enhancing the anti-vibration effect. The sliding adjustment function of the sliding seat 901 enables the anti-vibration member 9 to adapt to workpieces to be sprayed with different widths, improving the versatility of the equipment. The rotation of the rotating wheel 902 can effectively reduce the friction force with the workpiece to be sprayed, avoid damaging the surface of the workpiece, and can also better adapt to the small displacement of the workpiece. The driving effect of the first rotation driving member 903 ensures the active rotation of the rotating wheel 902, enhancing the stability and reliability of the anti-vibration effect. The cooperation of the sliding seat 901, the rotating wheel 902 and the first rotation driving member 903 in the anti-vibration member 9 provides a more effective guarantee for the stability of the large cross-section workpiece during the transfer process.

[0060] Further, there are a plurality of spray guns 4 which are arranged on the spray gun rotating frame.

[0061] In this embodiment, in the large cross-section workpiece spraying device, a plurality of spray guns 4 are provided and arranged on the spray gun rotating frame. The multiple spray guns 4 are arranged at a certain spacing and angle. When spraying a large workpiece to be sprayed, the multiple spray guns 4 work simultaneously, can cover a larger area, and improve the spraying efficiency. The multiple spray guns 4 operate simultaneously, greatly shortening the spraying time and improving the production efficiency. The arranged spray guns 4 can more evenly cover the surface of the workpiece to be sprayed, ensuring the quality and consistency of the coating. According to the shapes and sizes of different workpieces to be sprayed, the arrangement mode and angle of the spray guns 4 can be flexibly adjusted, increasing the adaptability of the equipment. The multiple arranged spray guns 4 provide strong support for the rapid and high-quality spraying of large cross-section workpieces to be sprayed.

[0062] Further, it further includes a rotating connector 12, the rotating connector 12 is arranged on the rotating frame of the spray gun 4, and the second rotating driving member 13 is arranged on the lifting frame 1 of the spray gun 4 to drive the rotating connector 12 to rotate.

[0063] In this embodiment, in the spraying device for large cross-section workpieces, the rotating connector 12 is installed on the rotating frame of the spray gun 4, and the second rotating driving member 13 is arranged on the lifting frame 1 of the spray gun 4. During actual operation, when it is necessary to adjust the angle of the rotating frame of the spray gun 4, the second rotating driving member 13 is started to drive the rotating connector 12 to rotate, thereby driving the rotating frame of the spray gun 4 to change the angle. During the spraying process, precise spraying needs to be performed on different parts of the workpiece. By controlling the rotation of the rotating connector 12 with the second rotating driving member 13, the angle of the rotating frame of the spray gun 4 can be adjusted quickly and accurately. The automatic adjustment of the angle of the rotating frame of the spray gun 4 is realized, improving the convenience and efficiency of operation. The spraying angle of the spray gun 4 can be controlled more precisely, meeting the spraying requirements for different parts of the workpiece and improving the spraying quality. The cooperation between the second rotating driving member 13 and the rotating connector 12 makes the rotation of the rotating frame of the spray gun 4 more stable and reliable, reducing the errors and fluctuations during the angle adjustment process. The arrangement of the rotating connector 12 and the second rotating driving member 13 further improves the performance and flexibility of the spraying device for large cross-section workpieces.

[0064] Further, it further includes an operating platform 14, and the operating platform 14 is arranged on one side of the lifting frame 1.

[0065] In this embodiment, in the spraying device for large cross-section workpieces, the operating platform 14 is arranged on one side of the lifting frame 1. The operating platform 14 is equipped with various control buttons, a display screen, an operating handle, etc. When the operator is performing spraying operations, he can stand in front of the operating platform 14 and precisely control the lifting height of the lifting frame 1, the rotation angle of the spray gun 4, the sliding position of the spray gun 4, the number of spray guns 4 used, and other related parameters through the control device on the operating platform 14. The operating platform 14 provides a centralized and convenient operating area for the operator, making the operation more efficient and comfortable. The operating platform 14 is located on one side of the lifting frame 1, facilitating the operator to observe the spraying situation in real time and make corresponding adjustments in a timely manner. The centralized operation control design reduces the complexity of the operation and the possibility of misoperation. The arrangement of the operating platform 14 greatly improves the operation convenience and controllability of the spraying device for large cross-section workpieces.
