[0002] Utility model disclosure CN220563891U discloses a printing cloth winding device, including a worktable. A vertical plate is provided on the upper surface of the worktable. Two second rotating shafts are symmetrically and rotatably connected to the surface of the vertical plate. A first rotating shaft is rotatably connected to the surface of the vertical plate between the two second rotating shafts. A first gear disk is connected to one end of the first rotating shaft. Two second gear disks are meshed on both sides of the first gear disk. A fixed cylinder is provided on one side of the second gear disk.

Detailed Implementation

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0021] Reference Figure 1-4 A printing cloth winding device includes a base 1, on which a first movable frame 2 and a second movable frame 3 are mounted. The first movable frame 2 and the second movable frame 3 are parallel to each other, and each has a driven roller 4 rotatably connected to its top end. The base 1 is provided with four guide rails 5. A positioning frame 6 is slidably connected to two guide rails 5 that are parallel to each other at the same end. The positioning frame 6 is shaped like a gate and wraps around both sides of the first movable frame 2 and the second movable frame 3, as well as above the two driven rollers 4. A column 7 is provided on one end extension of the base 1. A top rod 8 is provided on the column 7. An electric telescopic rod 9 is provided on the top rod 8. A fixed frame 10 is provided on the telescopic shaft of the electric telescopic rod 9. A first motor 11 is provided at one end of the fixed frame 10. A transmission roller 12 is provided on the output shaft of the first motor 11. The transmission roller 12 is parallel to the two driven rollers 4 and is arranged above the symmetrical center of the two driven rollers 4.

[0022] By arranging the first movable frame 2 and the second movable frame 3 in parallel, the two driven rollers 4 provide support for the lower end of the paper tube used for winding the inkjet cloth. The fixed frame 10 is lowered by the electric telescopic rod 9, so that the bottom end of the transmission roller 12 contacts the upper end of the paper tube used for winding the inkjet cloth. Driven by the first motor 11, the transmission roller 12 drives the paper tube to rotate and press and wind the inkjet cloth. Compared with the prior art, the winding of the inkjet cloth is separated from the rotating roller, which facilitates the installation of the paper tube before winding the inkjet cloth and the removal of the paper tube along with the rolled inkjet cloth after winding. The positioning frame 6 is set to achieve the positioning of the end of the inkjet cloth during winding, ensuring the neatness of the end of the inkjet cloth when it is rolled up. Furthermore, the movable effect of the positioning frame 6 allows for adaptive adjustment according to the width of the inkjet cloth.

[0023] Specifically, in this embodiment, the base 1 is provided with two ear plates 13, and a bidirectional screw 14 is rotatably connected inside the two ear plates 13. A second motor 15 is provided on one end of the bidirectional screw 14. The first moving frame 2 is driven to the positive thread section of the bidirectional screw 14, and the second moving frame 3 is driven to the negative thread section of the bidirectional screw 14, so as to realize the effect of adjustable spacing between the first moving frame 2 and the second moving frame 3. Thus, according to the phenomenon that the outer diameter of the inkjet cloth gradually increases after it is rolled up, the spacing between the two driven rollers 4 can be increased to prevent the inkjet cloth from falling off due to the reduction of the contact surface.

[0024] Specifically, in this embodiment, two guide rods 16 are provided between the two ear plates 13. Both guide rods 16 are parallel to the bidirectional screw 14. The first moving frame 2 and the second moving frame 3 are slidably connected to the two guide rods 16, thereby improving the stability of the movement of the first moving frame 2 and the second moving frame 3.

[0025] Specifically, in this embodiment, a number of ball bearings 17 are rotatably connected to the ends of the two positioning frames 6 that are close to each other, so as to reduce the friction between the inkjet cloth and the positioning frame 6 when the inkjet cloth is rotated and rolled up.

[0026] Specifically, in this embodiment, a sliding groove 18 is provided on the bottom end of the positioning frame 6, and the guide rail 5 is arranged in the sliding groove 18. The cross sections of both the guide rail 5 and the sliding groove 18 are trapezoidal to ensure horizontal sliding effect and improve vertical stability.

[0027] Specifically, in this embodiment, a bolt 19 is threadedly connected to the end of the positioning frame 6. The threaded end of the bolt 19 passes through the slide groove 18 and contacts the top of the guide rail 5, thereby achieving the locking effect after the horizontal position of the positioning frame 6 is adjusted.

[0028] Specifically, in this embodiment, the bottom of the base 1 is provided with several casters 20 with built-in brakes to facilitate movement and relocation, as well as stable parking after movement.

[0029] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
