[0002] With the continuous development of product decoration techniques, traditional transfer printing technology can hardly meet the diverse decorative needs of complex-shaped products. Flexible film water transfer paper forming devices have emerged as a result, capable of accurately transferring various exquisite patterns onto product surfaces, greatly expanding the possibilities of product decoration and showing broad application prospects.

[0003] Chinese utility model patent CN202122116446.9 discloses a flexible film water transfer printing paper forming device, including a support frame, a worktable, a flexible film roller mounting bracket, a PVA solution spraying mechanism, an automatic water transfer printing paper handling mechanism, and a heating mechanism. The worktable is positioned above the support frame and arranged along the running direction of the flexible film; the flexible film roller mounting bracket is located at one end of the worktable and is used to mount the flexible film roller; the PVA solution spraying mechanism and the automatic water transfer printing paper handling mechanism are both located on the side of the worktable; a heating mechanism mounting groove is provided on the worktable corresponding to the automatic water transfer printing paper handling mechanism, and the heating mechanism is disposed within the heating mechanism mounting groove. This utility model facilitates the automated preparation of flexible film water transfer printing paper, achieving high preparation efficiency and effectively ensuring the forming quality of the flexible film water transfer printing paper.

[0004] However, the spacing between the PVA solution nozzles in the above device is fixed. This means that when encountering large flexible films, the nozzles cannot effectively coat the films, and it may be necessary to replace the nozzles to expand the coating area, which is not conducive to the coating work. Utility Model Content

[0005] In view of this, the present invention provides a flexible film water transfer paper forming device. The main technical problem to be solved is that the spacing between the PVA solution nozzles is fixed, which means that when encountering a large flexible film, the nozzles cannot spray the film well, and it may be necessary to replace the nozzles to expand the spraying area, which is not conducive to the spraying work.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a flexible film water transfer printing paper forming device, comprising a mounting frame, a first motor fixedly connected to the side wall of the mounting frame, a double-threaded lead screw fixedly connected to the output end of the first motor, a moving block threadedly connected to the outer surface of the double-threaded lead screw, two moving blocks, a deflection arm movably mounted on the lower surface of the moving block, a moving plate movably mounted on the end of the deflection arm away from the moving block, a variable pitch groove provided on the side wall of the moving plate, multiple variable pitch grooves, a sliding rod provided inside the variable pitch groove, an inner circle outer square composite tube fixedly connected to the side wall of the sliding rod, a pipe fixedly connected to the upper surface of the inner circle outer square composite tube, a nozzle fixedly connected to the lower surface of the inner circle outer square composite tube, a first sliding block fixedly connected to the side wall of the inner circle outer square composite tube, a first sliding groove provided on the side wall of the mounting frame, and the first sliding block located inside the first sliding groove.

[0007] As a further description of the above technical solution:

[0008] The end of the sliding rod away from the inner circle and outer square composite tube is fixedly connected to a first connecting block, and the side of the first connecting block away from the sliding rod is fixedly connected to a second sliding block. The side wall of the mounting frame is provided with a second sliding groove, and the second sliding block is located inside the second sliding groove.

[0009] By adopting the above technical solution, both the first connecting block and the second sliding block can limit the movement of the sliding rod and the inner circle outer square composite tube, preventing the sliding rod and the inner circle outer square composite tube from shifting during the movement.

[0010] As a further description of the above technical solution:

[0011] The side wall of the movable plate has two limiting grooves, and the side wall of the mounting frame is fixedly connected to two limiting blocks, which are located inside the limiting grooves.

[0012] By adopting the above technical solution, the limiting block and the limiting groove work together to limit the up and down movement of the moving plate, thus preventing the moving plate from shifting during the movement.

[0013] As a further description of the above technical solution:

[0014] The side wall of the mounting frame is provided with a movable groove, the inner wall of the movable groove is fixedly connected with a limiting rod, and the outer surface of the limiting rod is fitted with a movable block.

[0015] By adopting the above technical solution, the limiting rod can limit the movement of the moving block.

[0016] As a further description of the above technical solution:

[0017] A mounting plate is provided below the mounting frame. There are two mounting plates. A second connecting block is fixedly connected to the upper surface of the mounting plate. The mounting frame is fixedly connected to the side wall of the second connecting block.

[0018] By adopting the above technical solution, the second connecting block is used to connect the mounting frame and the mounting plate together.

[0019] As a further description of the above technical solution:

[0020] A second motor is fixedly connected to the side wall of the mounting plate, and a drive roller is fixedly connected to the output end of the second motor. A driven roller is movably installed between adjacent mounting plates, and a conveyor belt is sleeved between the drive roller and the driven roller.

[0021] By adopting the above technical solution, the second motor can drive the active roller to rotate, which in turn can drive the conveyor belt and the driven roller to rotate, thereby moving the flexible film on the conveyor belt, which facilitates the subsequent spraying of PVA solution and drying.

[0022] As a further description of the above technical solution:

[0023] A heating box is fixedly connected to the upper surface of the mounting plate, and a heating ring is fixedly connected to the inner top of the heating box.

[0024] By adopting the above technical solution, the flexible film can be heated when passing through the heating box, thereby causing the PVA solution on the surface of the flexible film to solidify.

[0025] By employing the above technical solution, the flexible film water transfer printing paper forming device of this utility model has at least the following beneficial effects:

[0026] Compared with existing technologies, this flexible film water transfer printing paper forming device comprises a first motor, a double-threaded screw, moving blocks, a deflecting arm, a moving plate, a variable pitch groove, a sliding rod, an inner-circle outer-square composite tube, a pipe, and a nozzle. When the spraying range of the nozzle needs to be adjusted, the first motor is driven to rotate the double-threaded screw, which in turn causes adjacent moving blocks to move closer together, thereby causing the deflecting arm to deflect, which in turn causes the moving plate to descend. This causes the sliding rod to move inside the variable pitch groove, gradually increasing the distance between adjacent sliding rods, and thus causing adjacent inner-circle outer-square composite tubes, pipes, and nozzles to move closer together. The increased nozzle distance increases the spraying area. When the spraying area needs to be reduced, simply drive the first motor to rotate the double-threaded screw in the opposite direction. Compared to existing water transfer paper forming devices, where the spacing between PVA solution nozzles is fixed, this can lead to insufficient spraying of large flexible films, potentially requiring nozzle replacement to expand the spraying area, which is detrimental to the spraying process. This flexible film water transfer paper forming device can expand the spraying area of ​​the nozzles as needed, making it more widely applicable and beneficial for the spraying process.

A first motor 2 is fixedly connected to the side wall of the mounting frame 1. A double-threaded lead screw 3 is fixedly connected to the output end of the first motor 2. A moving block 4 is threadedly connected to the outer surface of the double-threaded lead screw 3. There are two moving blocks 4. A deflection arm 5 is movably mounted on the lower surface of the moving block 4. A moving plate 6 is movably mounted on the end of the deflection arm 5 away from the moving block 4. A variable pitch groove 7 is opened on the side wall of the moving plate 6. There are multiple variable pitch grooves 7, each with a different inclination and the same vertical height. A sliding rod 8 is provided inside the variable pitch groove 7. An inner circle outer square composite pipe 9 is fixedly connected to the side wall of the sliding rod 8. A pipe 10 is fixedly connected to the upper surface of the inner circle outer square composite pipe 9. The pipe 10 can be connected to an external water pipe to supply PVA solution. The PVA solution flows into the inner circle outer square composite pipe 9 through the pipe 10 and then through the inner circle outer square composite pipe. The sprayed material 9 flows into the nozzle 11 and is finally sprayed outward through the nozzle 11. The nozzle 11 is fixedly connected to the lower surface of the inner circle outer square composite tube 9. The first sliding block 13 is fixedly connected to the side wall of the inner circle outer square composite tube 9. The side wall of the mounting frame 1 is provided with a first sliding groove 12. When it is necessary to adjust the spraying range of the nozzle 11, the first motor 2 is driven to work and drive the double threaded screw 3 to rotate, which in turn drives the adjacent moving blocks 4 to move closer to each other, which in turn drives the deflection arm 5 to deflect, which in turn drives the moving plate 6 to descend, which in turn causes the sliding rod 8 to move inside the pitch groove 7, which in turn causes the distance between the adjacent sliding rods 8 to gradually increase, which in turn increases the distance between the adjacent inner circle outer square composite tube 9, pipe 10 and nozzle 11, thus increasing the spraying area of ​​the nozzle 11. When it is necessary to reduce the spraying area, it is only necessary to drive the first motor 2 to drive the double threaded screw 3 to rotate in the opposite direction. The first sliding block 13 is located inside the first sliding groove 12.

[0039] A first connecting block 14 is fixedly connected to the end of the sliding rod 8 away from the inner circle and outer square composite tube 9. A second sliding block 15 is fixedly connected to the side of the first connecting block 14 away from the sliding rod 8. A second sliding groove 16 is provided on the side wall of the mounting frame 1. Both the first connecting block 14 and the second sliding block 15 can limit the movement of the sliding rod 8 and the inner circle and outer square composite tube 9, preventing them from shifting during movement. The second sliding block 15 is located inside the second sliding groove 16. A limit groove 17 is provided on the side wall of the moving plate 6. There are two slots 17. The side wall of the mounting frame 1 is fixedly connected to a limiting block 18. There are two limiting blocks 18. The limiting blocks 18 and the limiting slots 17 cooperate with each other to limit the up and down movement of the moving plate 6 and prevent the moving plate 6 from deviating during the movement. The limiting blocks 18 are located inside the limiting slots 17. The side wall of the mounting frame 1 is provided with a moving groove 19. The inner wall of the moving groove 19 is fixedly connected to a limiting rod 20. The limiting rod 20 can limit the movement of the moving block 4. The outer surface of the limiting rod 20 is fitted with the moving block 4.

[0040] A mounting plate 22 is provided below the mounting frame 1. There are two mounting plates 22. A second connecting block 21 is fixedly connected to the upper surface of the mounting plate 22. The second connecting block 21 connects the mounting frame 1 and the mounting plate 22 together. The mounting frame 1 is fixedly connected to the side wall of the second connecting block 21. A second motor 23 is fixedly connected to the side wall of the mounting plate 22. A drive roller 24 is fixedly connected to the output end of the second motor 23. A driven roller 25 is movably mounted between adjacent mounting plates 22. A conveyor belt 26 is sleeved between the drive roller 24 and the driven roller 25. The operation of motor 23 can drive the active roller 24 to rotate, which in turn drives the conveyor belt 26 and the driven roller 25 to rotate, thereby moving the flexible film on the conveyor belt 26 to facilitate the subsequent spraying of PVA solution and drying. A heating box 27 is fixedly connected to the upper surface of the mounting plate 22. When the flexible film passes through the heating box 27, it can be heated and the PVA solution on the surface of the flexible film can be solidified. A heating ring 28 is fixedly connected to the inner top of the heating box 27. The heating ring 28 is equipped with an electric heating wire, which can generate heat when energized.

[0041] Working principle: When it is necessary to adjust the spraying range of the nozzle 11, the first motor 2 is driven to rotate the double threaded screw 3, which in turn causes the adjacent moving blocks 4 to move closer to each other, which in turn causes the deflection arm 5 to deflect, which in turn causes the moving plate 6 to descend, which causes the sliding rod 8 to move inside the pitch groove 7, which in turn causes the distance between the adjacent sliding rods 8 to gradually increase, which in turn increases the distance between the adjacent inner circle outer square composite pipe 9, pipe 10 and nozzle 11, thereby increasing the spraying area of ​​the nozzle 11. When it is necessary to reduce the spraying area, it is only necessary to drive the first motor 2 to rotate the double threaded screw 3 in the opposite direction.
