[0026] Example 1, please refer to Figures 1-7 This utility model provides the following technical solution: Specifically, it refers to a rotary spray painting machine for wooden door processing, including a spray painting component 1 fixedly installed on a processing machine tool, a positioning component 2 rotatably fitted inside the bottom of the spray painting component 1, the positioning component 2 including a base component 3 rotatably fitted on the spray painting component 1 and two fixing components 4 slidably fitted on the base component 3; the spray painting component 1 includes a base plate 101 fixedly installed on the processing machine tool, a rotating sleeve 102 fixed on the top of the base plate 101; the base component 3 includes a rotating sleeve 102 rotatably fitted on the rotating machine tool via bearings. Inside the sleeve 102 is a rotating shaft 301, with a base plate 302 fixed to its top. The top of the base plate 302 has two symmetrical sets of guide grooves 303, and two symmetrical sliding holes 304 are formed through it. The fixing member 4 includes a pressing rod 401 that slides within the sliding holes 304. A base platform 402 is fixed to the bottom of the pressing rod 401. A return spring 403, sleeved on the pressing rod 401, is fixed between the base platform 402 and the base plate 302. L-shaped springs are fixed to opposite sides of the base platform 402. The L-shaped lever 404 and the fixing member 4 also include two clamping plates 405. The clamping plates 405 are slidably fitted inside a set of guide grooves 303. A displacement plate 406 is fixed at the bottom of the clamping plate 405. The side of the displacement plate 406 is provided with a slanted groove 407 that is slidably fitted with the L-shaped lever 404. Two symmetrical limiting grooves 305 are provided on the inner wall of the sliding hole 304. Two downwardly extending positioning grooves 306 are provided on the top of the bottom plate 302 inside the sliding hole 304. Two limiting rails 408 are fixed on the periphery of the extrusion rod 401 and are respectively slidably fitted inside the limiting grooves 305. Two positioning plates 409 are fixed on the periphery of the extrusion rod 401 and are respectively slidably fitted with the positioning grooves 306. The top of the extrusion rod 401 is dome-shaped. A protective pad 410 is fixed on the inner wall of the clamping plate 405.

[0027] The specific application of this embodiment is as follows: Before painting the surface of a wooden door, the wooden door to be painted is moved and placed on top of the base plate 302 using an external mobile device. During placement, the wooden door gradually approaches the rounded tips of the two pressing rods 401 until the surface of the wooden door contacts the rounded tips of the two pressing rods 401. Under its own gravity, the door begins to press down on the rounded tips of the two pressing rods 401, causing the two pressing rods 401 to slide downwards synchronously inside the two sliding holes 304. (When the two pressing rods 401 slide downwards synchronously inside the two sliding holes 304, to prevent circumferential rotation, they are circumferentially rotated through the sliding fit between the limiting rail 408 and the limiting groove 305.) (Rotation limit), thereby causing the return spring 403, which is fixedly connected between the base platform 402 and the base plate 302, to be stretched synchronously (after the paint dries over a period of time, the stretched return spring 403 will separate from the top of the wooden door and the base plate 302, thereby causing the two extrusion rods 401 to move upward in the two sliding holes 304 respectively, so that the other side of the wooden door can be painted later. The top of the base plate 302 is provided with a flexible protective pad to protect the paint surface from scratches. The flexible protective pad and the protective pad 410 are made of the same material and have a strong protective effect. The flexible protective pad is not shown in the existing technical drawings and will not be described in detail here), so that the L fixed to the two sides of the base platform 402 is relatively... The L-shaped levers 404 slide inside the inclined grooves 407 that penetrate the sides of the two displacement plates 406. Through the sliding process of the two L-shaped levers 404, a force is generated on the two displacement plates 406 to bring them closer together. This causes the clamping plates 405 fixed to the top of the two displacement plates 406 to move in a straight line closer to each other inside a set of guide grooves 303 until the protective pads 410 fixed to the inner wall of the clamping plates 405 are in contact with the outer periphery of the wooden door. The positioning and clamping process of the wooden door is then completed. (After the positioning and clamping process of the wooden door is completed, the round top end of the pressing rod 401 is flush with the top of the bottom plate 302. At this time, in order to prevent the pressing rod 401 from sliding out of the sliding hole 304, the bottom of the positioning plate 409 is in contact with the inner bottom of the positioning groove 306.) In this way, the wooden door to be painted is positioned and fixed before painting by the weight of the wooden door itself, replacing the original method of external tool clamping and positioning, and simplifying the operation steps of the whole process.

[0028] Example 2, please refer to Figures 1-7This embodiment two is an improvement on embodiment one as follows: Specifically, a rotating gear 307 is fixed to the circumferential side of the rotating shaft 301; a drive motor 103 is fixed to the top of the base plate 101, and a main gear 104 meshing with the rotating gear 307 is fixed to the output shaft of the drive motor 103; two symmetrical L-shaped vertical plates 105 are fixed to the circumferential side of the base plate 101, and each of the two L-shaped vertical plates 105 has a downwardly extending vertical groove 106 on its outer top; a supporting base plate 107 is fixed to one outer side of one L-shaped vertical plate 105 near the bottom; a telescopic cylinder 108 is fixed to the top of the supporting base plate 107; a top plate 109 that slides between the two vertical grooves 106 is fixed to the telescopic end of the telescopic cylinder 108; a first ring pipe 110, a second ring pipe 111, and a third ring pipe 112 are sequentially arranged at the bottom of the top plate 109, and a flow path is connected between the first ring pipe 110, the second ring pipe 111, and the third ring pipe 112. The first ring pipe 110 has an inlet pipe 114 connected to its outer periphery. The first ring pipe 110, the second ring pipe 111, and the third ring pipe 112 are all equipped with paint spray nozzles 115 on their outer periphery. The end of the inlet pipe 114 is connected to a first connector 116. A paint storage tank 117 is fixed to the top of the base plate 101. A suction pump 118 is fixed to the outer periphery of the paint storage tank 117. A second connector 119 is fixed to the output end of the suction pump 118. A circulation hose 120 is connected between the first connector 116 and the second connector 119. A paint pouring pipe is connected to the outer periphery of the paint storage tank 117. A solenoid valve is provided on the periphery of the paint pouring pipe (after the paint inside the paint storage tank 117 is used up, external paint can be added to the paint storage tank 117 by opening the solenoid valve on the periphery of the paint pouring pipe. The paint pouring pipe and the solenoid valve are existing technologies and are not shown in the figure, so they will not be described in detail here).

[0029] A specific application of this embodiment is as follows: When the wooden door to be painted is positioned and clamped and fixed on the top of the base plate 302, the telescopic cylinder 108 is activated, causing the top plate 109 fixed to the telescopic end of the telescopic cylinder 108 to move downward between the two vertical grooves 106. This causes the paint spraying heads 115, which are provided on the outer periphery of the first ring tube 110, the second ring tube 111, and the third ring tube 112, to gradually approach the surface of the wooden door. After the paint spraying heads 115 have moved to the specified height, the telescopic cylinder 108 is closed, and the drive motor 103 is immediately started. This drives the main gear 104 fixed to the output shaft of the drive motor 103 to rotate, causing the rotating gear 307 meshing with it to rotate. This causes the rotating shaft 301 fixed to the bottom of the base plate 302 to rotate synchronously in the rotating sleeve 10. 2. The internal rotation causes the wooden door, which is positioned and clamped on the top of the base plate 302, to rotate synchronously. During the rotation, the suction pump 118 is activated simultaneously, causing the paint stored in the paint tank 117 to enter the first ring pipe 110 through the second connector 119, circulation hose 120, first connector 116, and liquid inlet pipe 114. Then, the paint enters the second ring pipe 111 and the third ring pipe 112 through the flow pipe 113 in the first ring pipe 110, and finally is sprayed out from the paint nozzles 115 through the first ring pipe 110, second ring pipe 111, and third ring pipe 112. This allows for rotational painting of the wooden door surface after positioning and clamping, avoiding uneven painting and improving the painting effect of the wooden door surface.
