The limit column cooperates with the reset mechanism to achieve the extrusion of carriers of different thicknesses. As the platform seat drives the limit column to move, the limit column stretches and tightens the carrier at both ends while combing the carrier to avoid wrinkles on the carrier.

[0018] 3. This is a double-workbench UV inkjet printer. After the hard carrier is placed on the fixed plate, the two ends of the hard carrier can contact the two ends of the platform seat. The supporting mechanism pushes the platform seat inward to clamp and fix the hard carrier. The printing seat can be adjusted in height during printing. While adjusting the height of the printing seat, the distance between the lighting lamp on the curing seat and the printing carrier is controlled. The ultraviolet light from the lighting lamp is used to quickly dry the printed ink. The lighting lamp is distributed in a straight line on the printing carrier. When the printing seat moves back and forth, the linear carrier can be cured over a large area. BRIEF DESCRIPTION OF THE DRAWINGS

[0027] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0028] See also Figures 1 to 7 The present invention provides a technical solution: a double-worktable UV inkjet printer, comprising a fixed box 1, a fixed base 2 welded on the top of the fixed box 1, a guide rail 3 welded on the fixed base 2, a movable base 4 movably installed between the guide rail 3 and the fixed base 2, a support base 10 fixed between the movable base 4, a motor box 8 fixedly installed inside the movable base 4, a slot 5 is opened on the side of the fixed base 2, a limiting track 6 and a tooth plate 7 are welded inside the slot 5, a fixed plate 14 is welded on the fixed base 2, a platform base 12 is movably installed on the top of the fixed plate 14, a support plate 13 is movably installed inside the platform base 12, a maintenance plate 9 is movably installed on the side of the fixed box 1, a driving motor drives the gear to rotate on the tooth plate 7, and the driving motor drives the movable base 4 to move horizontally on the fixed base 2 to adjust its position.

[0029] In this embodiment, a driving motor is fixed inside the motor box 8, and a gear is installed on the driving motor, and the gear is rotatably installed on the tooth plate 7. A protrusion is fixed on the inner wall of the movable seat 4, and the protrusion is movably installed on the top of the limit rail 6. A switch 15 is fixedly installed at one end of the fixed seat 2, and the switch 15 includes an operation button and an emergency stop button. A slide groove 11 is opened on the support seat 10, and a slider 19 is movably installed inside the slide groove 11. A mounting seat 21 is fixed on the side of the slider 19, and a transmission belt 20 is movably installed on one side of the mounting seat 21. A lifting mechanism 22 is fixed on the top of the mounting seat 21, and a movable column 29 is installed on the lifting mechanism 22. A printing seat 23 is fixed at one end of the movable column 29. The lifting mechanism 22 is a linear reciprocating electric push rod. The lifting mechanism 22 pushes the printing seat 23 up and down, and the printing seat 23 moves up and down to realize the height of the nozzle and the printing carrier for printing.

[0030] In this embodiment, a baffle 24 is welded inside the platform seat 12, and the baffle 24 is movably mounted on the bottom of the support plate 13. A limiting groove 16 is opened on the side of the fixed seat 2, and a limiting block 17 is movably installed inside the limiting groove 16. One end of the limiting block 17 is fixed to the side of the platform seat 12, and a supporting mechanism 25 is fixed inside the limiting groove 16. One end of the supporting mechanism 25 is fixed on the limiting block 17. A fixing hole 27 is opened at one end of the platform seat 12, and the inside of the fixing hole 27 A reset mechanism 28 is fixedly installed, and a limiting column 26 is fixed at one end of the reset mechanism 28. A printing assembly 32 is fixedly installed inside the printing seat 23. A mounting hole 30 is opened inside the support seat 10, and a fixing groove 33 is opened at one end of the mounting hole 30. A curing seat 35 is movably installed inside the fixing groove 33. The support mechanism 25 and the reset mechanism 28 are both supporting springs. The support mechanism 25 pushes the limiting block 17 to move inward at the same time, and always moves inward to return to its position when the platform seat 12 is not limited.

[0031] In this embodiment, a support column 34 is fixed on the curing seat 35, and the support column 34 is movably installed inside the mounting hole 30. An elastic mechanism 31 is fixed on the inner wall of the mounting hole 30. The elastic mechanism 31 is a spring. The elastic mechanism 31 pushes the curing seat 35 to move up and down inside the fixing groove 33. One end of the elastic mechanism 31 is fixed on the support column 34. A lighting lamp 36 is fixedly installed on the curing seat 35. An arc groove 37 is provided at the bottom of the curing seat 35. A limiting wheel 38 is movably installed inside the arc groove 37. A support frame 39 is installed on the limiting wheel 38. The support frame 39 is fixed to the top of the printing seat 23. A clamping hole 18 is provided on the fixing plate 14. The clamping hole 18 is movably contacted with one end of the limiting column 26. After the limiting column 26 moves inside the clamping hole 18, it limits and fixes the platform seat 12.

[0032] When the device is in use, the object to be printed is laid flat on the support plate 13 of the platform seat 12. After the object is laid flat, the driving motor is started to drive the support seat 10 to move back and forth on the fixed seat 2. When the support seat 10 moves slowly back and forth, the mounting seat 21 and the printing seat 23 move back and forth horizontally. When the printing seat 23 moves horizontally, the printing assembly 32 completes the printing work. The printing assembly 32 includes a printing head, which preferably moves from one end of the fixed seat 2 to the other end when printing. After the printing of the carrier on one of the platform seats 12 is completed, the platform seat 12 is moved horizontally outward. When the platform seat 12 moves outward, the printing seat 23 realizes the printing of the carrier on the other platform seat 12. When the platform seat 12 moves, the limit block 1 7 moves inside the limiting groove 16, and the limiting block 17 squeezes the support mechanism 18 when it moves, causing the support mechanism 18 to squeeze and shrink. When the limiting column 26 at the bottom of the platform seat 12 moves to the top of the clamping hole 18, the limiting column 26 cooperates with the clamping hole 18 to limit the platform seat 12, and pushes the support plate 13 upward from the bottom of the platform seat 12. The bottom of the support plate 13 is separated from the baffle 24, and the printing carrier is quickly disassembled through the support plate 13. After the carrier is taken out of the support plate 13, the support plate 13 is installed on the baffle 24 for limiting and fixing. The limiting column 26 on the platform seat 12 is pushed to separate from the clamping hole 18, and the platform seat 12 loses its limit and moves back to its original position under the push of the support mechanism 25;

[0033] When it is necessary to limit and fix the two ends of the carrier, the carrier is laid flat on the fixing plate 14, and the carrier is installed on the fixing plate 14 under the extrusion of the limiting column 26. As the platform seat 12 moves, the limiting column 26 cooperates with the reset mechanism 28 to realize the extrusion of carriers of different thicknesses. As the platform seat 12 drives the limiting column 26 to move, the limiting column 26 stretches and tightens the carrier to both ends while combing the carrier to avoid wrinkles on the carrier. When the limiting column 26 moves to the inside of the card hole 18, the limiting column 26 pushes the carrier into the inside of the card hole 18 to realize the limit fixation of the platform seat 12 and the carrier. After the hard carrier is placed on the fixed plate 14, the two ends of the hard carrier can contact the two ends of the platform seat 12, and the supporting mechanism 25 pushes the platform seat 12 inward to achieve clamping and fixing of the hard carrier. During printing, the printing seat 23 can be adjusted in height through the lifting mechanism 22. While adjusting the height of the printing seat 23, the distance between the lighting lamp 36 on the curing seat 35 and the printing carrier is controlled. The ultraviolet light is irradiated by the lighting lamp 36 to achieve rapid drying of the printed ink. The lighting lamp 36 is distributed in a straight line on the printing carrier. When the printing seat 23 moves back and forth, the linear carrier can be used for large-area curing.
