[0012] The present invention provides a trailer for a painting device. It has the following beneficial effects: (1) Through the setting of the limiting device in the present invention, the cooperation of the bidirectional screw, the first runner, the threaded sleeve, the fixing plate, the fixing block, the second motor, the rotating shaft, the second runner, and the belt enables the rotation of the bidirectional screw to drive the two threaded sleeves to move towards each other. The movement of the two threaded sleeves drives the fixing plate to move. The movement of the fixing plate limits painting devices of different sizes, thus avoiding the problem that the painting device deviates when moving up and down following the support plate, resulting in the device losing balance and increasing the risk of tipping. At the same time, through the cooperation of the folding bladder, the pulling plate, the connecting rod, the telescopic hose, the suction block, and the fixing block, the movement of the pulling plate stretches the folding bladder, so that the folding bladder extracts the air at the suction port of the suction block through the telescopic hose. When the fixing plate contacts the painting device, the suction block adsorbs on the surface of the painting device, further enhancing the effect of fixing the painting device.

[0013] (2) Through the setting of the spraying device in the present invention, the cooperation of the pressing member, the telescopic connecting pipe, the nozzle, the resisting rod, and the fixing block enables the pressing member to control the lubricating liquid inside the liquid storage tank to be sprayed from the nozzle to the suction port of the suction block through the telescopic connecting pipe, thereby reducing the friction between the suction block and the coating equipment and improving the adsorption effect. At the same time, through the cooperation of the coating ring and the fixing block, when the fixing plate moves, it will drive the coating ring to move, and the movement of the coating ring will evenly apply the lubricating liquid on the surface of the bidirectional screw rod, effectively reducing the wear between the bidirectional screw rod and the threaded sleeve, thereby extending the service life of the equipment. At the same time, through the cooperation of the brush block, the V-shaped diversion block, and the liquid collection tank, the movement of the brush block will push the lubricating liquid inside the long groove to the V-shaped diversion block, so that the lubricating liquid enters the inside of the liquid collection tank through the V-shaped diversion block, thereby collecting the lubricating liquid and avoiding the waste of the lubricating liquid.

[0014] (3) Through the setting of the knocking device in the present invention, the cooperation of the L-shaped resisting block, the arc-shaped knocking block, the connecting plate, and the arc block enables the L-shaped resisting block to be reset by the elastic force of the spring. The reset of the L-shaped resisting block will drive the arc-shaped knocking block to be reset, and the reset of the arc-shaped knocking block will knock on the fixing plate. In this way, the arc-shaped knocking block will continuously knock on the fixing plate, causing the fixing plate to vibrate. The vibration of the fixing plate can cause the suction block to vibrate, and the vibration of the suction block can increase the flow of the surface lubricating liquid, thereby accelerating the speed of the lubricating liquid covering the suction port of the suction block.

The output shaft of the first motor 4 is fixedly connected with a threaded rod 5. The bottom of the threaded rod 5 is fixedly connected to the bottom inner wall of the first U-shaped frame 3. A support plate 11 is threadedly connected to the circumferential surface of the threaded rod 5. The side surface of the support plate 11 is in contact with the inner wall of the first U-shaped frame 3. A limiting device 6 is provided on the top of the support plate 11. The limiting device 6 includes a long groove 61. The long groove 61 is opened on the top of the support plate 11. A bidirectional screw 62 is rotatably installed on the inner wall of the long groove 61. On the circumferential surface of the bidirectional screw 62 without threads, a first runner 63 is fixedly connected. On the circumferential surfaces of the bidirectional screw 62 with opposite thread directions, two thread sleeves 64 are respectively threadedly connected. The two thread sleeves 64 are in contact with the inner wall of the long groove 61. The tops of the two thread sleeves 64 are both fixedly connected with fixing plates 65. Two fixing blocks 66 are fixedly connected to the bottom of the support plate 11. On the side surface of one of the fixing blocks 66, a second motor 67 is fixedly connected. The output shaft of the second motor 67 is fixedly connected with a rotating shaft 68. A second runner 69 is fixedly connected to the circumferential surface of the rotating shaft 68. A belt 610 is connected for transmission between the second runner 69 and the first runner 63. On the side of the top of the base 1 away from the first U-shaped frame 3, a second U-shaped frame 9 is fixedly connected. A long rod 10 is fixedly connected to the inner wall of the second U-shaped frame 9. The top of the support plate 11 on the side away from the threaded rod 5 is slidably installed on the circumferential surface of the long rod 10. A moving component 2 is provided at the bottom of the base 1. The moving component 2 includes a turntable. The top of the turntable is rotatably connected to the bottom of the base 1. A moving wheel is fixedly connected to the bottom of the turntable. Through the setting of the above structure, the movement of the fixing plate 65 will limit painting devices of different sizes, thus avoiding the problem that the painting device deviates when moving up and down with the support plate 11, resulting in the equipment losing balance and increasing the risk of tipping.

[0019] The limiting device 6 further includes two limiting plates 611. The tops of the two limiting plates 611 are both fixedly connected to the bottom of the support plate 11. On the side surfaces of the two limiting plates 611, folding bags 612 are fixedly connected. On the side away from the limiting plate 611 of the folding bag 612, a pulling plate 613 is fixedly connected. A connecting rod 614 is fixedly connected to the bottom of the fixing plate 65. The end of the connecting rod 614 away from the fixing plate 65 is fixedly connected to the side surface of the pulling plate 613. A telescopic hose 615 is fixedly connected to the bottom of the folding bag 612. The end of the telescopic hose 615 away from the folding bag 612 is fixedly connected with a suction block 616. The suction block 616 is fixedly installed on the inner wall of the fixing plate 65. Through the setting of the above structure, the folding bag 612 extracts the air at the suction port of the suction block 616 through the telescopic hose 615, so that when the fixing plate 65 contacts the painting device, the suction block 616 adsorbs on the surface of the painting device, further enhancing the effect of fixing the painting device.

[0020] The top of the support plate 11 is provided with a spraying device 7, which includes a liquid storage tank 71. A pressing member 72 is fixedly connected to the side of the liquid storage tank 71 close to the fixed plate 65. The pressing member 72 here is The working principle is similar to that of a spray bottle. The pressing piece 72 is composed of a pressing part and a spring pump, so that resetting is achieved through the action of the spring pump's elastic force. The liquid reservoir 71 is fixedly connected to a telescopic connecting tube 73 on one side near the fixed plate 65. The telescopic connecting tube 73 is fixedly connected to a spray nozzle 74 on the end away from the liquid reservoir 71. The top of the fixed plate 65 is fixedly connected to a resistance rod 75. The pressing piece 72 is used to control the lubricating liquid on the inner wall of the liquid reservoir 71 to be sprayed from the spray nozzle 74 through the telescopic connecting tube 73. The top of the liquid reservoir 71 is fixedly connected to a liquid inlet pipe 76. The pressing piece 72 is located on the displacement trajectory of the resistance rod 75, and the spray nozzle 74 is located above the suction block 616. Through the arrangement of the above structure, the pressing piece 72 controls the lubricating liquid inside the liquid reservoir 71 to be sprayed from the spray nozzle 74 to the suction port of the suction block 616 through the telescopic connecting tube 73, thereby reducing the friction between the suction block 616 and the coating equipment and improving the adsorption effect.

[0021] A smear ring 77 is fixedly connected to the side of the threaded sleeve 64, and a brush block 78 is fixedly connected to the bottom of the smear ring 77. The inner wall of the smear ring 77 contacts the threaded surface of the bidirectional screw 62, and the bottom of the brush block 78 contacts the bottom of the inner wall of the long groove 61. Through the setting of the above structure, the movement of the smear ring 77 will evenly spread the lubricating liquid on the surface of the bidirectional screw 62, effectively reducing the wear between the bidirectional screw 62 and the threaded sleeve 64, thereby extending the service life of the equipment.

[0022] The two fixed blocks 66 are fixedly connected to a V-shaped guide block 79 on one side where they are close to each other, and are fixedly connected to a liquid collecting tank 710 on one side away from the V-shaped guide block 79. Through the arrangement of the above structure, the movement of the brush block 78 will push the lubricating liquid inside the long groove 61 to the V-shaped guide block 79, so that the lubricating liquid enters the interior of the liquid collecting tank 710 through the V-shaped guide block 79, thereby collecting the lubricating liquid and avoiding waste of the lubricating liquid.

[0023] During use, place the painting equipment on the surface of the support plate 11. Start the first motor 4. The output shaft of the first motor 4 will cause the threaded rod 5 to rotate. The rotation of the threaded rod 5 will cause the support plate 11 to move up and down along the inner walls of the first loop-shaped frame 3 and the second loop-shaped frame 9, so that the height can be adjusted according to the item to be painted. After the painting equipment is placed on the surface of the support plate 11, start the second motor 67. The output shaft of the second motor 67 will drive the rotating shaft 68 to rotate. The rotation of the rotating shaft 68 will drive the second runner 69 to rotate. The second runner 69 will drive the first runner 63 to rotate through the belt 610. The rotation of the first runner 63 will drive the bidirectional screw 62 to rotate. The rotation of the bidirectional screw 62 will drive the two threaded sleeves 64 to move towards each other. The movement of the two threaded sleeves 64 will drive the fixed plate 65 to move. The movement of the fixed plate 65 will limit painting equipment of different sizes, thus avoiding the problem that the painting equipment deviates when moving up and down with the support plate 11, resulting in the equipment losing balance and increasing the risk of tipping over. When the fixed plate 65 moves, the fixed plate 65 will drive the connecting rod 614 to move. The movement of the connecting rod 614 will drive the pulling plate 613 to move. The movement of the pulling plate 613 will stretch the folding bladder 612, so that the folding bladder 612 extracts the air at the suction port of the suction block 616 through the telescopic hose 615. Thus, when the fixed plate 65 contacts the painting equipment, the suction block 616 adsorbs on the surface of the painting equipment, further enhancing the effect of fixing the painting equipment.

[0024] When the fixed plate 65 no longer fixes the painting equipment, the bidirectional screw 62 will drive the two threaded sleeves 64 to move in opposite directions. The movement of the threaded sleeve 64 will drive the contact rod 75 to move. The movement of the contact rod 75 will squeeze the pressing part 72, so that the pressing part 72 controls the lubricating liquid in the liquid storage tank 71 to be sprayed from the nozzle 74 to the suction port of the suction block 616 through the telescopic connecting pipe 73, thus reducing the friction between the suction block 616 and the painting equipment and improving the adsorption effect. The excess lubricating liquid will drip onto the inner surface of the long groove 61 and the surface of the bidirectional screw 62. When the fixed plate 65 moves, it will drive the coating ring 77 to move. The movement of the coating ring 77 will evenly apply the lubricating liquid on the surface of the bidirectional screw 62, effectively reducing the wear between the bidirectional screw 62 and the threaded sleeve 64, thereby extending the service life of the equipment. At the same time, the movement of the coating ring 77 will drive the brush block 78 to move. The movement of the brush block 78 will push the lubricating liquid in the long groove 61 to the V-shaped diversion block 79, so that the lubricating liquid enters the liquid collection tank 710 through the V-shaped diversion block 79, thereby collecting the lubricating liquid and avoiding waste of the lubricating liquid.

[0025] Please refer to Figures 1 - 8, on the basis of the above embodiments, in another embodiment of the present invention, a knocking device 8 is provided on the top of the fixing plate 65. The knocking device 8 includes a U-shaped block 81. The bottom of the U-shaped block 81 is fixedly connected to the top of the fixing plate 65. An L-shaped abutting block 82 is slidably connected to the inner wall of the U-shaped block 81. A spring is provided between the L-shaped abutting block 82 and the U-shaped block 81. A connecting plate 84 is fixedly connected to the side surface of the support plate 11. A plurality of arc-shaped blocks 85 are fixedly connected to the top of the connecting plate 84. An arc-shaped knocking block 83 is fixedly connected to the top of the inner wall of the L-shaped abutting block 82. The bottom of the L-shaped abutting block 82 is arc-shaped. The plurality of arc-shaped blocks 85 are located on the displacement track of the arc-shaped surface of the L-shaped abutting block 82. The arc-shaped knocking block 83 is in contact with the support plate 11. Through the setting of the above structure, the arc-shaped knocking block 83 continuously knocks on the fixing plate 65, so that the fixing plate 65 vibrates. The vibration of the fixing plate 65 can make the suction block 616 vibrate. The vibration of the suction block 616 can increase the flow of the surface lubricant, thereby accelerating the speed of the lubricant covering the suction port of the suction block 616.

[0026] During use, the movement of the fixing plate 65 will drive the U-shaped block 81 to move. The movement of the U-shaped block 81 will drive the L-shaped abutting block 82 to move. The movement of the L-shaped abutting block 82 will drive the arc-shaped knocking block 83 to move. When the arc surface of the L-shaped abutting block 82 abuts against the arc-shaped block 85, the L-shaped abutting block 82 will move upward. The upward movement of the L-shaped abutting block 82 will compress the spring. The upward movement of the L-shaped abutting block 82 will drive the arc-shaped knocking block 83 away from the fixing plate 65. When the arc surface of the L-shaped abutting block 82 does not abut against the arc-shaped block 85, the L-shaped abutting block 82 will be reset by the elastic force of the spring. The reset of the L-shaped abutting block 82 will drive the arc-shaped knocking block 83 to be reset. The reset of the arc-shaped knocking block 83 will knock on the fixing plate 65. In this way, the arc-shaped knocking block 83 continuously knocks on the fixing plate 65, so that the fixing plate 65 vibrates. The vibration of the fixing plate 65 can make the suction block 616 vibrate. The vibration of the suction block 616 can increase the flow of the surface lubricant, thereby accelerating the speed of the lubricant covering the suction port of the suction block 616.
