Technical Field

[0001] The utility model relates to the technical field of coating, and specifically to uniform drying and curing equipment for a coating line. Background Art

[0002] A coating line is an automated production line used to coat the surface of a product during the production process. In a coating line, the paint is usually sprayed on the surface of the product, and then needs to be dried and cured to ensure that the coating can adhere firmly to the surface of the product. Uniform drying and curing equipment is a key component in this process, which has an important impact on the quality and performance of the coating.

[0003] The patent specification with the announcement number CN 219168829U discloses a uniform drying and curing device for a coating line, through a workbench, a conveyor belt is symmetrically installed on the surface of the workbench, a drying device is arranged above the workbench, a plurality of placement blocks are fixedly installed on the surfaces of the two conveyor belts, a placement groove is opened on the surfaces of the plurality of placement blocks, a rotating roller is placed in each of the two placement grooves, and a pressure rod is symmetrically fixedly installed on the inner wall of the drying device through a plurality of groups of elastic components, and the two ends of the rotating roller are respectively in rolling contact with the lower surfaces of the two pressure rods. When the utility model dries the coated material, the material is conveyed to the drying device with the action of the conveyor belt, and then, under the cooperation of the placement blocks, the elastic components, the pressure rod and the rotating roller, the rotating roller can drive the material to rotate continuously in the drying device, thereby drying each surface of the material evenly, effectively improving the production qualification rate.

[0004] However, in the implementation of the relevant technology, the existing uniform drying and curing equipment for coating lines has the following problems: the electric heating rod of the drying box is fixedly installed, and the material is rotated, squeezed and dried by rotating the roller, which easily causes the surface of the material to bend and crack. At the same time, the drying box cannot adjust the distance between the coating line and the heating rod according to the drying environment to improve the drying efficiency. For this reason, we propose a uniform drying and curing equipment for coating lines. Utility Model Content

[0030] Embodiment 2: An equipment bin 4 is provided at the bottom end of the drying box 1, and a servo motor 17 is installed on the outer wall of one side of the drying box 1. The output shaft of the servo motor 17 is connected to a screw rod 18. One end of the screw rod 18 passes through the inner walls of the drying box 1 and the equipment bin 4 and is movably installed on the inner wall of the other side of the drying box 1. The outer wall of the equipment bin 4 is symmetrically installed with threaded sleeves 19.

[0031] In this embodiment, a second mounting block 23 is installed at the bottom end of the equipment bin 4, a telescopic rod 20 is installed at the top end of the second mounting block 23, a tray 21 is installed at the end of the telescopic rod 20 away from the second mounting block 23, and a transmission rod 22 is symmetrically hingedly connected to the outer wall of the bottom end of the tray 21, one end of the transmission rod 22 is hingedly connected to the outer walls on both sides of the threaded sleeve 19, a slider 24 is installed on the outer wall of the bottom end of the threaded sleeve 19, and a slide groove 25 is provided on the inner wall of the bottom end of the drying box 1, and the bottom end of the threaded sleeve 19 is movably mounted on the inner wall of the bottom end of the drying box 1 through the slider 24 and the slide groove 25.

[0035] Specific as Figure 1 , Figure 3 and Figure 4As shown, when this structure is used, the servo motor 17 is started, and the screw rod 18 is driven to rotate by the servo motor 17. The internal thread arranged on the inner wall of the threaded sleeve 19 and the external thread symmetrically arranged on the outer wall of the screw rod 18 as well as the limiting effect of the slider 24 and the slide groove 25 on the threaded sleeve 19 are utilized to make the threaded sleeve 19 retract along the outer wall of the screw rod 18. Then, through the hinged connection structure between the tray 21 and the transmission rod 22, the threaded sleeve 19 lifts the tray 21 upward through the transmission rod 22 during movement, and pulls the telescopic rod 20 to telescope and move upward, thereby retracting the distance between the storage plate 16 and the UV curing drying lamp 15, so that the coating line is closer to the UV curing drying lamp 15 to speed up the drying speed.

[0036] Working principle: manually pull the handle 3 outward to open the closed box door 2, place the coating line neatly on the storage plate 16, close the closed box door 2, energize and heat the UV curing drying lamp 15, start the telescopic cylinder 10, and push and pull the rack 9 back and forth through the telescopic movement of the telescopic cylinder 10. The rack 9 is limited by the limit groove 7 and the limit block 8 to keep the rack 9 moving on the same horizontal line. The tooth block arranged on the outer wall of the bottom end of the rack 9 is used to mesh with the gear 13 during movement, so that the rack 9 drives the gear 13 to rotate clockwise and counterclockwise when moving back and forth, so that it drives the rotating shaft 12 to turn forward and backward, and then drives the UV curing drying lamp 15 to swing through the rotating shaft 12 to change the irradiation angle of the UV curing drying lamp 15. When the drying speed needs to be accelerated, the servo motor 17 is started and the gear 13 is meshed with the gear 13 to rotate clockwise and counterclockwise when the rack 9 moves back and forth. The servo motor 17 drives the screw rod 18 to rotate, and the threaded sleeves 19 on both sides of the screw rod 18 are rotated in opposite directions through the external threads symmetrically arranged on the outer walls of both sides of the screw rod 18 and the internal threads matched with the threaded sleeves 19 arranged on the inner walls of the threaded sleeves 19. The slider 24 and the slide groove 25 limit the threaded sleeves 19, so that the threaded sleeves 19 on both sides are close to each other and retracted. The transmission rod 22 is then used to make the threaded sleeves 19 and the tray 21 hingedly connected. When the threaded sleeve 19 drives the transmission rod 22 to retract, the transmission rod 22 generates a vertical upward force on the tray 21, so that the telescopic rod 20 is lifted upward, and the tray 21 pushes the storage plate 16 to move upward and pull it into the distance between it and the UV curing drying lamp 15. This structure can not only dry the coating line in all aspects, but also adjust the drying speed and speed up the drying efficiency.

[0037] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
