DETAILED DESCRIPTION

[0022] The following will be combined with the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] The turning structure of the coating machine refers to the design of the machine that enables the workpiece or coating to be turned over during the coating process. This design allows the coating machine to turn over the coating surface of the workpiece or coating during the coating process, which can be used to meet various coating requirements.

[0024] The clamping mechanism in existing equipment can play a role in clamping and fixing the pipe. However, the way that the two ends of the pipe are fixed by the sleeve will cause the problem of poor comprehensiveness of the pipe coating. The main reason is that the fixed part blocks the spray head or brush applicator of the coating equipment, so that these parts cannot be coated. Figure 1-Figure 4 , a flip structure for a coating machine is provided, including a machine platform 1, a top of the machine platform 1 is provided with an adjustment mechanism 2 and a positioning mechanism 3 which is synchronously driven by the adjustment mechanism 2 and is used to fix the object to be coated without obstruction.

[0025] refer to Figure 1As shown, the device cannot adapt to the positioning requirements of objects of different sizes, so the device will not be able to flexibly adapt to the coating work of objects of different sizes, which will limit the scope of application of the device and make it only applicable to objects within a specific size range, and cannot meet diversified production needs. In order to improve the versatility and applicability of the coating machine, the following settings are made: the adjustment mechanism 2 includes a motor 21 fixed to the right side of the machine table 1, and the output end of the motor 21 is fixedly connected to a bidirectional threaded screw 22, and the surface of the bidirectional threaded screw 22 is threadedly connected to two adjustment blocks 23. A long groove is provided on the front side of the machine table 1, and a limit groove is provided on the inner wall of the long groove. The side of the adjustment block 23 is fixedly connected to a limit block sliding in the limit groove, which plays a role in limiting the displacement path of the adjustment block 23. The sides of the two adjusting blocks 23 are fixedly connected with a connecting frame 24, and the ends of the connecting frame 24 away from the adjusting blocks 23 are fixedly connected with a mounting plate 25. The top of the machine platform 1 is fixedly connected with a slideway 26 slidably connected to the bottom end of the mounting plate 25. The mounting plate 25 is rotatably connected to one of the mounting plates 32. The motor 21 is started to drive the bidirectional threaded screw 22 to rotate at the output end. The rotation of the bidirectional threaded screw 22 causes the two adjusting blocks 23 on its outer wall to move relative to or away from each other according to the length of the object, so that the connecting frame 24 drives the mounting plate 25 to slide in the slideway 26, causing the two mounting plates 32 to move relative to or away from each other to position the pipeline object, thereby making the equipment flexible and adjustable, and able to adapt to the positioning requirements of objects of different sizes.

[0026] refer to Figure 3-Figure 4As shown, the clamping mechanism in the existing equipment can play the role of clamping and fixing the pipeline. However, the way in which the two ends of the pipeline are fixed by being sleeved will cause the problem of poor comprehensiveness of pipeline coating. The main reason is that the fixed parts block the spray head or brush coater of the coating equipment, thereby causing these parts to be unable to be coated. In order to ensure the integrity of the coating, the following settings are made. The positioning mechanism 3 includes two mounting plates 32 arranged on the top of the machine 1, and the opposite sides of the two mounting plates 32 are fixedly connected with mounting cylinders 36. The outer wall of the mounting cylinder 36 away from the end of the mounting plate 32 is fixedly connected with an annular plate 312. The side of the annular plate 312 away from the mounting cylinder 36 is provided with a rotating plate 311, and the circumferential surface of the rotating plate 311 is provided with a plurality of fastening plates 31 in an annular manner and equidistantly. The material of the fastening plates 31 is rubber material. The side of the mounting plate 32 close to the mounting cylinder 36 is provided with a power assembly for driving the rotating plate 311 to rotate so that the plurality of fastening plates 31 are synchronously expanded and closely attached to the inner wall of the object to be coated. The power assembly includes an annular elastic airbag 34 fixed on the side of the mounting plate 32 close to the mounting cylinder 36. The side of the annular elastic airbag 34 away from the mounting plate 32 is fixedly connected with a contact plate 33. After the pipeline object is sleeved on the outside of the plurality of fastening plates 31, the adjustment mechanism 2 is started to gradually approach the two mounting plates 32 so that the pipeline object is sandwiched between the two contact plates 33. At this time, the two mounting plates 32 continue to approach so that the two contact plates 33 are pushed to squeeze the annular elastic airbag 34. The inner wall of the mounting plate 32 is fixedly connected with a connecting pipe 35. The two ends of the connecting pipe 35 are fixedly connected with the annular elastic airbag 34 and the mounting cylinder 36 respectively. The internal sliding sleeve of the mounting cylinder 36 is provided with a piston 37. The internal gas of the annular elastic airbag 34 is transmitted into the mounting cylinder 36 through the connecting pipe 35 to push the piston 37. The movement of the piston 37 pushes the threaded rod 38 to move. The side of the piston 37 is rotatably connected to a threaded rod 38. The thread on the outer wall of the threaded rod 38 is a thread of a specific angle, and the spacing between the threads is large. The outer wall of the threaded rod 38 is threadedly connected to a driving ring 39 fixedly connected to the inner wall of the mounting cylinder 36. A rotating cylinder 310 is provided at the end of the threaded rod 38 away from the piston 37. The threaded rod 38 is slidably sleeved inside the rotating cylinder 310. The end of the rotating cylinder 310 away from the threaded rod 38 penetrates the inner wall of the mounting cylinder 36 and extends to the outside of the mounting cylinder 36. A rotating plate 311 is fixed to the end of the rotating cylinder 310 away from the threaded rod 38. During the displacement of the threaded rod 38, it is threadedly connected and rotated with the driving ring 39. During the rotation of the threaded rod 38, it is gradually placed in the rotating cylinder 310. Since the outer wall of the threaded rod 38 extending to one end of the rotating cylinder 310 is fixedly connected with a slider, the inner wall of the rotating cylinder 310 is provided with a sliding groove for the sliding of the slider, causing the rotating cylinder 310 to rotate synchronously with the rotation of the threaded rod 38, thereby driving the rotating plate 311 to rotate.The rotating plate 311 has a plurality of drive grooves equidistantly arranged in an annular shape, and a sliding rod 313 is slidably sleeved inside the plurality of drive grooves. The annular plate 312 has a plurality of grooves on one side close to the rotating plate 311, and a push plate 314 fixedly connected to the sliding rod 313 is slidably connected inside the plurality of grooves. The fastening plate 31 is fixed to the end of the push plate 314 away from the sliding rod 313. The sliding rod 313 is affected by the rotation of the rotating plate 311 in the drive groove and pushes the push plate 314 to slide in the groove, thereby causing the fastening plate 31 to expand synchronously to fit tightly against the inner wall of the pipeline object, thereby achieving an unobstructed fixing effect, which can effectively solve the problem of incomplete coating caused by clamping and fixing the pipeline object, thereby improving the coating quality and production efficiency.

[0027] refer to Figure 1-Figure 2 As shown, a flip mechanism 4 for driving the coated object to flip and coat is provided on the side of the machine 1. The flip mechanism 4 includes a motor 2 41 fixed on the machine 1. The output end of the motor 2 41 is fixedly connected to a rotating rod 42. The outer wall of the rotating rod 42 is fixedly connected to a pulley 1. The outer wall of the pulley 1 is provided with a belt. The pulley 1 drives the pulley 2 to rotate through the belt. The inner wall of the pulley 2 is fixedly connected to another rotating rod 42, so that two pipe objects can be coated in all directions at the same time. The outer wall of the rotating rod 42 is provided with a rotating cylinder 43. The outer wall of the rotating rod 42 is fixedly connected to a rotating block. The inner wall of the rotating cylinder 43 is provided with a long slide groove for the rotating block to slide, so that the adjusting mechanism 2 can still drive the pipe object to rotate after the flip mechanism 4 is adjusted. The rotating drum 43 is fixedly connected to another mounting plate 32. After the pipeline object is fixed, the second motor 41 is started to make the rotating rod 42 drive the rotating drum 43 to rotate, thereby rotating the two mounting plates 32, and then making the pipeline object fixed between the two mounting plates 32 rotate synchronously, so as to achieve the effect of turning over and coating the pipeline object.
