Description

Technical Field

[0001] This utility model relates to the field of track plate spraying technology, and specifically to a surface spraying device for track plate processing. Background Technology

[0002] Track shoes are key chassis wear parts for construction machinery such as excavators and bulldozers. Their surfaces need to be painted to meet the requirements of corrosion prevention, rust prevention, and aesthetics. At present, in order to improve the painting efficiency, the common practice in the industry is to install multiple spray guns on the painting equipment and use a conveying mechanism such as a conveyor chain to make the workpiece pass through the painting area at a uniform speed to achieve full coverage painting. Some advanced devices will also integrate paint mist recovery, drying, and even demisting systems in order to improve environmental protection and automation.

[0003] The existing fixed-spacing multi-spray gun arrangement has inherent defects. When the model of the track plate to be sprayed changes or the spray gun model is changed, the operator must manually adjust the position of each spray gun one by one. The process is cumbersome and time-consuming, which seriously affects production efficiency and is difficult to adapt to the needs of flexible manufacturing. In addition, although the spraying device disclosed in authorization announcement numbers CN216296804U and CN218796734U has improved the convenience of operation or achieved double-sided spraying to a certain extent by setting a movable spraying mechanism or a flipping mechanism, the spacing of its spray gun group is still fixed. This makes it difficult to optimize the spraying trajectory and atomization effect when spraying different models of workpieces, which can easily cause serious "overspraying" of narrow workpieces, insufficient edge coverage of wide workpieces, or affect the uniformity of the coating due to electrostatic interference.

[0004] Based on this, the present invention designs a surface spraying device for processing track plates to solve the above problems. Utility Model Content

[0005] In view of the above-mentioned shortcomings of the existing technology, the present invention provides a surface spraying device for processing track plates.

[0006] To achieve the above objectives, this utility model provides the following technical solution: A surface spraying device for processing track plates includes a mounting frame and two sets of fixed frames symmetrically distributed on the mounting frame. Multiple sets of spray guns are equally spaced on both sets of fixed frames. Track plates are provided below the mounting frame and are located in the middle of the two sets of fixed frames. The two sets of fixed frames are equipped with adjustment mechanisms for adjusting the distance between multiple sets of spray guns. The adjustment mechanism includes multiple sets of equidistantly distributed adjustment frames and guide frames that are slidably mounted on the fixed frames. Both sets of fixing brackets are slidably connected to the mounting bracket; Furthermore, each of the multiple sets of adjustment frames is slidably connected to the fixed frame and the guide frame, with the upper adjustment frame fixedly installed on the fixed frame and the lower adjustment frame fixedly installed on the guide frame. The multiple sets of spray guns are fixedly installed on the corresponding adjustment frames, and infrared transmitters and infrared receivers are fixedly installed on the two upper sets of adjustment frames, respectively.

[0007] Furthermore, the adjustment mechanism also includes a mounting rod fixedly installed on the fixed frame, a first telescopic rod slidably installed inside the mounting rod, a second telescopic rod slidably installed inside the first telescopic rod, and the end of the second telescopic rod away from the mounting rod being fixedly connected to the guide frame.

[0008] Furthermore, a threaded rod is rotatably installed inside the mounting rod, the lower end of which passes through the first telescopic rod and is threadedly connected to it. A threaded tube is rotatably installed inside the first telescopic rod, the lower end of which passes through the second telescopic rod and is threadedly connected to it.

[0009] Furthermore, the threaded rod has two sets of symmetrical keyways, and the threaded tube has two sets of symmetrical key blocks. The two sets of key blocks are correspondingly arranged with the two sets of keyways, and the threaded tube is slidably connected to the threaded rod through the key blocks and keyways.

[0010] Furthermore, the two adjacent sets of adjustment frames are connected by a linkage mechanism. The linkage assembly includes two sets of first and second linkages that are distributed crosswise and hinged to each other in the middle. The left ends of the two sets of first linkages are rotatably connected by a pivot, and the right ends of the two sets of second linkages are rotatably connected by a pivot.

[0011] Furthermore, each of the two sets of first connecting rods has a slider rotatably mounted on its right end, and the slider is slidably connected to the corresponding adjusting frame. The left ends of the two sets of second connecting rods are rotatably connected to the corresponding adjusting frames through rotating shafts.

[0012] Furthermore, the mounting bracket is equipped with a bidirectional lead screw, the two ends of which pass through the mounting bracket and are rotatably connected to the mounting bracket through rolling bearings. The two ends of the bidirectional lead screw also pass through two sets of fixing brackets and are threadedly connected to the two sets of fixing brackets respectively.

[0013] Compared with the prior art, the advantages of this utility model are as follows: 1. By setting a special adjustment mechanism on two sets of fixed frames and cooperating with the sliding connection between the fixed frames and the mounting frame, the inherent defects of fixed-spacing multi-spray gun arrangement in the prior art are effectively solved. For scenarios where the model of the track plate to be painted changes or the spray gun model is changed, it is not necessary for the operator to manually adjust the position of each spray gun one by one. The adjustment mechanism can drive multiple sets of spray guns to synchronously adjust the spacing. The sliding cooperation between the guide frame and multiple sets of adjustment frames provides stable guidance for the spray gun spacing adjustment. The nested structure of the mounting rod, the first telescopic rod and the second telescopic rod can flexibly change the overall length of the adjustment mechanism. The threaded rod and the threaded tube can be synchronously driven to extend and retract the first telescopic rod and the second telescopic rod to move the adjustment frame in linkage through the sliding sleeve design of the key block and the keyway. The cross linkage mechanism between adjacent adjustment frames can also ensure that multiple sets of spray guns always maintain an equidistant distribution during the adjustment process, which greatly simplifies the adjustment process, shortens the adjustment time, significantly improves production efficiency, and effectively adapts to the needs of frequent switching of processing objects in flexible manufacturing. 2. Two sets of fixed brackets are driven by a bidirectional screw to slide along the mounting frame, allowing for flexible adjustment of the overall distance between the two sets of fixed brackets. Combined with the fine adjustment of the spray gun spacing on a single set of fixed brackets by the adjustment mechanism, the overall distribution of the spray gun group and the spacing between individual guns can be optimized according to the size characteristics of different track plate models. For narrow track plates, overspraying can be avoided by reducing the spray gun spacing, reducing paint waste and lowering subsequent cleaning costs. For wide track plates, the spray gun coverage area can be reasonably expanded to ensure sufficient coverage of the edge areas. Furthermore, the optimized spray gun spacing can effectively avoid electrostatic interference caused by improper spray gun distribution, ensuring uniform and stable paint atomization, resulting in consistent coating thickness and stronger adhesion on the track plate surface, significantly improving the spraying quality and achieving the dual goals of trajectory optimization and effect assurance during the spraying process of different track plate models.

[0017] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0018] In some embodiments, please refer to the accompanying drawings. Figures 1-4 A surface spraying device for processing track plates includes a mounting frame 1 and a track plate 2, as well as two sets of fixing frames 3 symmetrically distributed on the mounting frame 1. Multiple sets of spray guns 4 are equally spaced on both sets of fixing frames 3. The track plate 2 is located in the middle of the two sets of fixing frames 3. The mounting frame 1 provides basic support for the entire device to ensure structural stability. The track plate 2 is placed in the middle of the two sets of fixing frames 3, which allows the spray guns 4 on the two sets of fixing frames 3 to spray the surface of the track plate 2 from both sides at the same time, achieving double-sided spraying coverage and improving spraying efficiency. The two sets of fixed frames 3 are equipped with adjustment mechanisms 8 for adjusting the spacing between multiple sets of spray guns 4. The multiple sets of spray guns 4 on the fixed frame 3 are initially distributed at equal intervals, which can initially ensure the uniformity of spraying. The adjustment mechanism 8 provides a structural basis for adjusting the spacing of the spray guns 4 according to the model of the track plate 2 or the model of the spray gun 4, avoiding the tedious manual adjustment one by one. Both sets of fixing brackets 3 are slidably connected to the mounting bracket 1. The slidable connection between the fixing bracket 3 and the mounting bracket 1 can change the overall distance between the two sets of fixing brackets 3, adapt to track plates 2 of different widths, and ensure that the track plates 2 are always within the optimal spraying range of the spray gun 4.

[0019] In some embodiments, such as Figure 2 , Figure 3 and Figure 4As shown in the preferred embodiment of this utility model, the adjustment mechanism 8 includes a guide frame 805 slidably mounted on the fixed frame 3. The adjustment mechanism 8 also includes multiple sets of equidistantly distributed adjustment frames 801 slidably mounted on the fixed frame 3 and the guide frame 805. The upper adjustment frame 801 is fixedly mounted on the fixed frame 3, and the lower adjustment frame 801 is fixedly mounted on the guide frame 805. Multiple sets of spray guns 4 are fixedly mounted on corresponding adjustment frames 801. Infrared emitters 6 and infrared receivers 7 are respectively fixedly mounted on the two upper sets of adjustment frames 801. The guide frame 805 can slide along the fixed frame 3, providing a unified guiding reference for the movement of the multiple sets of adjustment frames 801, preventing the spray guns 4 from being misaligned due to the offset of the adjustment frames 801. When the guide frame 805 slides, it drives the lower adjustment frame 801 to move synchronously. This, in turn, achieves the change in the spacing of the multiple sets of adjustment frames 801 through the linkage between the adjustment frames 801. The change in the spacing of the adjustment frames 801 drives the adjustment of the spray gun 4 spacing. The infrared emitter 6IR333C... The infrared emitting diode and the infrared receiver 7HS0038 integrated infrared receiver head are respectively installed on the two sets of adjustment brackets 801 above. The two are initially in the same straight line and are set accordingly to form a precise infrared monitoring optical path. Its core function is to monitor the distance between the two sets of adjustment brackets 801 in real time.

[0020] The adjusting mechanism 8 further includes a mounting rod 806 fixedly mounted on the fixed frame 3. A first telescopic rod 807 is slidably mounted inside the mounting rod 806, and a second telescopic rod 808 is slidably mounted inside the first telescopic rod 807. The end of the second telescopic rod 808 away from the mounting rod 806 is fixedly connected to the guide frame 805. A threaded rod 809 is rotatably mounted inside the mounting rod 806. The lower end of the threaded rod 809 passes through the first telescopic rod 807 and is threadedly connected to the first telescopic rod 807. A threaded tube 811 is rotatably mounted inside the first telescopic rod 807. The lower end of the threaded tube 811 passes through the second telescopic rod 808 and is threadedly connected to the second telescopic rod 808. Two sets of symmetrically distributed keyways 810 are provided on the threaded rod 809. Two sets of symmetrically distributed key blocks 812 are distributed inside the threaded tube 811. The two sets of key blocks 812 are correspondingly arranged with the two sets of keyways 810, and the threaded tube 811 is connected to the threaded rod 809 through the key blocks 812 and the keyways 810. The rod 809 is slidably sleeved, and the threaded rod 809 is threadedly connected to the first telescopic rod 807. When the threaded rod 809 rotates, it will drive the first telescopic rod 807 to move axially along the mounting rod 806 through the threaded transmission. The threaded tube 811 is slidably sleeved with the keyway 810 of the threaded rod 809 through the key block 812, so that the rotation of the threaded rod 809 can synchronously drive the rotation of the threaded tube 811, and the threaded tube 811 can slide along the axial direction of the threaded rod 809. The threaded tube 811 is threadedly connected to the second telescopic rod 808. When the threaded tube 811 rotates, it will drive the second telescopic rod 808 to move axially along the first telescopic rod 807. Through a single rotation of the threaded rod 809, the first telescopic rod 807 and the second telescopic rod 808 can be synchronously driven to extend and retract, realizing the stable movement of the guide frame 805. Then, the guide frame 805 drives the bottom adjustment frame 801 to move, ultimately realizing the synchronous and precise adjustment of the spacing of multiple spray guns 4 without adjusting each spray gun 4 individually, greatly improving the adjustment efficiency.

[0021] In some embodiments, such as Figure 3As shown, in a preferred embodiment of this utility model, adjacent sets of adjustment frames 801 are connected by a linkage mechanism. The linkage assembly includes two sets of first linkages 802 and second linkages 804 that are cross-distributed and hinged to each other in the middle. The left ends of the two sets of first linkages 802 are rotatably connected by a pivot, and the right ends of the two sets of second linkages 804 are rotatably connected by a pivot. A slider 803 is rotatably mounted on the right end of each set of first linkages 802, and the slider 803 is slidably connected to the corresponding adjustment frame 801. The left ends of the two sets of second linkages 804 are rotatably connected to the corresponding adjustment frame 801 by pivots. The linkage mechanism between adjacent adjustment frames 801 adopts a cross-hinged first linkage 802 and second linkage 804, forming a parallelogram-like structure, which has good linkage and stability. The left end of the first connecting rod 802 and the right end of the second connecting rod 804 are connected by a rotating shaft to ensure that the connecting rod assembly can extend and retract flexibly. The slider 803 at the right end of the first connecting rod 802 is slidably connected to the adjusting frame 801, and the left end of the second connecting rod 804 is rotatably connected to the adjusting frame 801. When the bottom adjusting frame 801 moves with the guide frame 805, it will drive the adjacent adjusting frame 801 to move synchronously through the pushing and pulling action of the connecting rod. The sliding of the slider 803 on the adjusting frame 801 can adapt to the change of the connecting rod angle, avoid the mechanism from jamming, and ensure that multiple sets of adjusting frames 801 always maintain an equal distance distribution during the spacing adjustment process. This ensures that the spacing of the spray guns 4 is uniform, prevents uneven coating thickness caused by abnormal spacing of some spray guns 4, and also disperses the adjustment force, making the adjustment process more stable and reducing the wear of the adjusting mechanism 8.

[0022] In some embodiments, such as Figure 2 As shown in the preferred embodiment of this utility model, a bidirectional lead screw 5 is installed on the mounting frame 1. The two ends of the bidirectional lead screw 5 pass through the mounting frame 1 and are rotatably connected to the mounting frame 1 through rolling bearings. The two ends of the bidirectional lead screw 5 pass through two sets of fixing frames 3 and are threadedly connected to the two sets of fixing frames 3 respectively. The threads at the two ends of the bidirectional lead screw 5 have opposite directions of rotation and are threadedly connected to the two sets of fixing frames 3 respectively. When the bidirectional lead screw 5 rotates clockwise or counterclockwise, it will drive the two sets of fixing frames 3 to move towards or away from each other along the mounting frame 1 through thread transmission, thereby changing the distance between the two sets of fixing frames 3. By adjusting the distance between the two sets of fixing frames 3, different widths of track plates 2 can be adapted, so that the spray gun 4 and the surface of the track plate 2 always maintain the optimal spraying distance, ensuring the atomization effect of the paint, reducing the problem of overspray or insufficient edge coverage, and also providing a basis for fine adjustment of the distance between the spray guns 4 on a single set of fixing frames 3, realizing the coordination of overall and local adjustments.

[0023] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
