[0027] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0028] like Figures 1 to 6As shown, the present invention provides a high-speed UV printer feed belt correction device, comprising a feed belt 1, wherein both ends of the feed belt 1 are respectively equipped with a driving roller 2 and a driven roller 3, both sides of the feed belt 1 are fixedly connected with a fixing plate 4, a guide mechanism 5 is installed at the bottom of one end of the feed belt 1 close to the driven roller 3, and a correction mechanism 6 is installed at one end of the fixing plate 4;

[0029] The guide mechanism 5 includes a cylinder 51, a moving block 52 fixedly connected to one end of the cylinder 51, two rotating rods 53 rotatably connected to both sides of the moving block 52, two supporting frames 54 rotatably connected to one end of the two rotating rods 53, and two leveling components 55 fixedly installed on the top of the two supporting frames 54.

[0030] The above scheme is adopted: the feed belt 1 is used as a carrier for transmitting the objects to be printed, ensuring that the objects can move smoothly on the device and provide a basic transportation path for the printing work. The active roller 2 provides power for the operation of the feed belt 1, and drives the feed belt 1 to move through its own rotation, ensuring that the feed belt 1 can continuously and stably transport objects. The driven roller 3 plays a role in auxiliary support and guidance of the feed belt 1, and works with the active roller 2 to ensure that the feed belt 1 maintains appropriate tension and straightness during operation. The design of the guide mechanism 5 avoids the problem of easy deviation of objects during placement and transportation. During the operation of the feed belt 1, if the object is uneven, the cylinder 51 is started to push the moving block 52 to move, and the moving block 52 drives the rotating rod 53 to move. The rotating rod 53 rotates the support frame 54, thereby adjusting the position of the flattening component 55 at the top of the support frame 54. The lifting plate 59 slides in the fixed frame 58 to guide the object. The printed pattern or text is not easy to be stretched, compressed or twisted, and it is not easy to cause a large deviation from the original design, which is conducive to ensuring the visual effect.

[0031] like Figures 1 to 6 As shown, there are two fixed plates 4, and grooves are provided at one end of the two fixed plates 4 close to the correcting mechanism 6. Support legs are fixedly installed at the bottom of the two fixed plates 4. The surface of the cylinder 51 is fixedly connected with a mounting plate, and the cylinder 51 is fixedly installed at the bottom of the feed belt 1 through the mounting plate. The two leveling components 55 include an auxiliary plate 56, a rotating shaft 57, a fixed frame 58 and a lifting plate 59. The rotating shaft 57 is rotatably connected to the inside of the auxiliary plate 56, and the auxiliary plate 56 is fixedly connected to the fixed frame 58 through the rotating shaft 57. The lifting plate 59 is slidably connected to the inside of the fixed frame 58. The other end of the auxiliary plate 56 is fixedly connected to the top of the support frame 54, and the bottom surface of the rotating shaft 57 is rotatably connected to the top surface of the fixed plate 4.

[0032] The above scheme is adopted: the fixed plate 4 provides stable side support for the feed belt 1 to prevent the feed belt 1 from lateral shaking during operation and ensure the stability of object transmission. The grooves are provided to provide installation and activity space for the components of the correction mechanism 6. The cylinder 51 is used as a power source to provide driving force for the movement of the moving block 52 and control the movement of the entire guide mechanism 5. The moving block 52 moves under the push of the cylinder 51, driving the rotating rod 53 and the support frame 54 connected thereto to move. The rotating rod 53 plays the role of connecting and transmitting movement, converting the linear motion of the moving block 52 into the rotational motion of the support frame 54. The support frame 54 supports and fixes the leveling component 55 so that it can adjust its position with the movement of the support frame 54. The auxiliary plate 56 provides an installation basis for the rotating shaft 57 and the fixed frame 58, and The support frame 54 is connected to the leveling component 55, and the rotating shaft 57 enables the fixed frame 58 to rotate relative to the auxiliary plate 56 to adjust the angle. The fixed frame 58 provides a sliding track and support for the lifting plate 59. The lifting plate 59 can move up and down as needed to flatten and sort the objects on the feed belt 1 to prevent the objects from being uneven on the feed belt 1. The leveling component 55 of the guide mechanism 5 flattens and sorts the objects on the feed belt 1 to ensure the flatness of the objects on the feed belt 1 and avoid problems such as distortion of the printing pattern and color deviation caused by uneven objects, thereby significantly improving the printing accuracy and quality. Stable feeding and accurate correction reduce the time for equipment downtime adjustment, so that the printing process can be carried out continuously and efficiently, thereby greatly improving the overall production efficiency.

[0033] like Figures 1 to 6As shown, a slide groove adapted to the lifting plate 59 is provided inside the fixed frame 58, a lifting rod 581 is fixedly connected to the top surface of one end of the fixed frame 58, one end of the lifting rod 581 is fixedly connected to a stabilizing column 582, the bottom surface of the stabilizing column 582 is connected to the top surface of the lifting plate 59, the deviation correction mechanism 6 includes a driver 61, a first worm 62, a first turbine 63, a threaded rod 64 and a synchronous belt 65, the output end of the driver 61 is fixedly connected to the top of the first worm 62, the first worm 62 is meshed with the first turbine 63, one end of the first worm 62 is fixedly connected to a first rotating wheel 66, the synchronous belt 65 is sleeved with the first rotating wheel 66, and the interior of the synchronous belt 65 is sleeved with The second rotating wheel, one end of the second rotating wheel is fixedly connected with the second worm, the surface of the second worm is meshingly connected with the second turbine, the internal thread of the second turbine is connected with a threaded column 67, the surface of the threaded column 67 and the threaded rod 64 are threadedly connected with an adjusting block 68, one side of the adjusting block 68 is fixedly connected with a baffle 69, the adjusting block 68 is adapted to the groove, and there are two adjusting blocks 68, and the opposite sides of the two adjusting blocks 68 are respectively connected to the two ends of the active roller 2, and the two fixed plates 4 are also fixedly connected with fixed plates at one end close to the deviation correction mechanism 6, and there are two groups of fixed plates, and the interiors of the two groups of fixed plates are respectively rotatably connected to the outer rings at both ends of the first worm 62 and the second worm.

[0034] The above scheme is adopted: the driver 61 provides power to drive the first worm 62 to rotate. The driver 61 serves as the power source of the entire deviation correction device. It is responsible for providing the initial driving force for the deviation correction process. The power outputted by the driver 61 triggers a series of mechanical actions through connection and transmission with other components, thereby realizing accurate deviation correction of the feed belt 1. Specifically, the driver 61 can accurately control the output speed and torque. By stably and continuously outputting power, it drives the first worm 62 to start rotating. This rotational motion is the starting action for the normal operation of the entire deviation correction mechanism 6. Under the action of the driver 61, the first worm 62 can rotate at a specific speed and force, thereby forming an effective meshing transmission with the first turbine 63. The first worm 62 and The first turbine 63 transmits the power of the driver 61 to the first rotating wheel 66 through meshing transmission, and drives the synchronous belt 65 to move. The first rotating wheel 66 and the synchronous belt 65 transmit the power to the second rotating wheel to realize synchronous transmission on both sides. The second rotating wheel, the second worm and the second turbine convert the power into the rotational movement of the threaded column 67 through mutual cooperation. The threaded rod 64 and the threaded column 67 drive the adjustment block 68 to move in the groove through rotation. The movement of the adjustment block 68 in the groove drives the baffle 69 to move, thereby adjusting and correcting the position of the objects on the feed belt 1 to prevent the objects from shifting. The fixing plate supports and fixes the first worm 62 and the second worm to ensure that they remain stable during rotation and reduce shaking and deviation. The accuracy and reliability of the correction mechanism 6 are improved. Through the design of the correction structure, the correction function of the feed belt 1 is achieved, and the tension of the feed belt 1 can be adjusted. When the feed belt 1 deviates, the driver 61 is started to drive the first worm 62 to rotate. The first worm 62 drives the first rotating wheel 66 to rotate by engaging with the first turbine 63. The first rotating wheel 66 rotates the second rotating wheel through the synchronous belt 65. The second rotating wheel drives the second worm to rotate. The second worm engages with the second turbine to rotate the threaded column 67. The rotation of the threaded column 67 and the threaded rod 64 causes the adjustment block 68 to move in the groove. The adjustment block 68 drives the driven roller 3 to move, so that the feed belt 1 can be corrected to avoid partial defects in the printed pattern caused by the deviation of the feed belt 1. The fixing plate supports and fixes the first worm 62 and the second worm, ensuring that they remain stable during rotation, reducing shaking and deviation, thereby improving the accuracy and reliability of the deviation correction mechanism 6. The fixing plate provides stable support and positioning for the first worm 62 and the second worm, and effectively limits the shaking and displacement of the worm during rotation, ensuring that the worm can accurately rotate along the predetermined axis. By being tightly connected to the outer rings at both ends of the first worm 62 and the second worm, the fixing plate bears the radial force and axial force generated when the worm rotates, thereby dispersing the influence of these forces on the entire device structure, which helps to reduce the friction and wear between the worm and other components.Prolong the service life of the worm and related transmission parts.

[0035] The working principle and use process of the present invention are as follows: the object to be printed is placed on the feed belt 1, the active roller 2 rotates under the drive of external power, driving the feed belt 1 to move, and the driven roller 3 assists in the rotation. During the operation of the feed belt 1, if the object is uneven, the cylinder 51 is started to push the moving block 52 to move, and the moving block 52 drives the rotating rod 53 to move, and the rotating rod 53 rotates the support frame 54, thereby adjusting the position of the flattening component 55 at the top of the support frame 54, and the lifting plate 59 slides in the fixed frame 58 to guide the object. When the feed belt 1 is offset, the driver 61 starts, driving the first worm 62 to rotate, and the first worm 62 drives the first rotating wheel 66 to rotate by engaging with the first turbine 63. The first rotating wheel 66 rotates the second rotating wheel through the synchronous belt 65. The second rotating wheel drives the second worm to rotate. The second worm engages with the second turbine to rotate the threaded column 67. The rotation of the threaded column 67 and the threaded rod 64 causes the adjustment block 68 to move in the groove, and the adjustment block 68 drives the driven roller 3 to move, so that the feed belt 1 can be corrected.
