[0002] A printing machine is a machine specifically designed for printing on textiles and other materials. It is commonly used to print patterns and designs on soft surfaces such as paper, fabric, and film. After the fabric is printed by the printing machine, it is usually rolled up by a take-up device. However, the existing take-up devices cannot roll up fabrics of different widths at the same time, which does not improve the practicality and rolling efficiency of the fabric take-up device.

[0003] Therefore, a new solution is needed to address this problem. Utility Model Content

[0017] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0018] Example:

[0019] A material receiving device for a printing machine, such as Figures 1 to 5 As shown, the device includes a base 1 and two side plates 2 integrally formed on the base 1. The two side plates 2 are located on both sides of the base 1, and an installation space 3 is formed between the two side plates 2. Multiple take-up rollers 4 of different lengths are rotatably installed in the installation space 3. The distance between the multiple take-up rollers 4 and the top surface of the base 1 increases sequentially from bottom to top along the height direction of the side plates 2. Multiple clamping components 5 for clamping the ends of the take-up rollers 4 are installed in the installation space 3. Multiple telescopic components 6 corresponding to the take-up rollers 4 are rotatably connected to one of the side plates 2. The telescopic ends of the telescopic components 6 are fixedly installed at one end of the take-up rollers 4 through connecting components 7.

[0020] The clamping assembly 5 includes two lower clamping blocks 501 and two upper clamping plates 502. The upper clamping plates 502 are rotatably connected to the top of the lower clamping blocks 501 via a rotating shaft. Both the upper clamping plates 502 and the lower clamping blocks 501 have arc-shaped grooves 8 on their sides that are close to each other, accommodating the ends of the take-up roller 4. The upper clamping plates 502 and the lower clamping blocks 501 are fixedly installed together by screws. Both the upper clamping plates 502 and the lower clamping blocks 501 have threaded holes for connection with the screws. The two lower clamping blocks 501 are slidably mounted on the base 1 via a spacing adjustment component. The two lower clamping blocks 501 can be moved closer together or... The distance adjustment component includes a lead screw 9. The top surface of the base 1 has multiple receiving grooves 10 corresponding to the winding roller 4. The lead screw 9 is rotatably connected inside the receiving grooves 10. The lead screw 9 includes a left-handed part 901 and a right-handed part 902. The left-handed part 901 and the right-handed part 902 are integrally formed and their thread directions are opposite. The end of the lead screw 9 near the left-handed part 901 is rotatably mounted on one of the side plates 2, and the end of the lead screw 9 near the right-handed part 902 passes through the other side plate 2. Two lower clamping blocks 501 are respectively screw-driven and connected to the left-handed part 901 and the right-handed part 902.

[0021] The telescopic assembly 6 includes a mounting cylinder 601 and a threaded rod 602. The threaded rod 602 is threaded into the interior of the mounting cylinder 601. The outer peripheral wall of the threaded rod 602 is machined with external threads, and the inner peripheral wall of the mounting cylinder 601 is machined with internal threads that mate with the outer peripheral wall of the threaded rod 602. The mounting cylinder 601 is rotatably mounted on one of the side plates 2. A motor is mounted on the side plate 2 near the mounting cylinder 601 by fastening bolts. The output end of the motor passes through the side plate 2 and is welded to one of the mounting cylinders 601. The outer peripheral wall of the mounting cylinder 601 is welded with a thread of the same shape. The shaft is equipped with a driving gear 11, and two adjacent driving gears 11 are connected by a driven gear 12. The driven gear 12 is rotatably mounted on the side plate 2 near the mounting cylinder 601 via a rotating shaft 2. The connecting assembly 7 is respectively installed at the end of the threaded rod 602 and the end of the take-up roller 4. The connecting assembly 7 includes a flange 701 welded to the end of the threaded rod 602 and a flange 702 welded to the end of the take-up roller 4. The flange 701 and the flange 702 are correspondingly arranged and are connected by bolts.

[0022] The user first places both ends of the take-up roller 4 into the grooves on the top of the two lower clamping blocks 501, then rotates the upper clamping plate 502 toward the top of the lower clamping blocks 501 until the grooves of both the upper clamping plate 502 and the lower clamping blocks 501 are in contact with the outer peripheral wall of the end of the take-up roller 4. Then, the screw is threaded into the threaded holes of the upper clamping plate 502 and the lower clamping blocks 501, respectively, so that the end of the take-up roller 4 is clamped and installed through the clamping assembly 5, until multiple take-up rollers 4 of different lengths are clamped and installed in the multiple clamping assemblies corresponding to the take-up roller 4. 5. The user then holds and rotates the threaded rod 602, moving it closer to the take-up roller 4. As the threaded rod 602 moves, it moves flange 701 until flange 701 and flange 702 are in contact. Bolts are then used to install flange 701 and flange 702 respectively. The motor is then started, driving one of the mounting cylinders 601 connected to its output end. The rotation of mounting cylinder 601 drives the connected drive gear 11 to rotate. Because adjacent drive gears... The drive gear 11 is connected by a driven gear 12. The driven gear 12 is rotatably mounted on one of the side plates 2, so that when one of the drive gears 11 rotates, it drives the adjacent driven gear 12 to rotate. Through the transmission between the drive gear 11 and the driven gear 12, it can simultaneously drive other drive gears 11 to rotate, and thus simultaneously drive the winding rollers 4 of different lengths connected to the end of the threaded rod 602 to rotate. This reduces the cost of setting up multiple motors to increase the material taking device, and enables the simultaneous winding of fabrics of different widths. Because the distance between the multiple winding rollers 4 and the top surface of the base 1 increases sequentially from bottom to top along the height direction of the side plate 2, the multiple winding rollers 4 of different lengths will not interfere with each other when winding at the same time, avoiding affecting the winding of the fabric. The winding roller 4 corresponding to the width of the fabric is selected and used in the installation space 3 according to the width of the fabric. Multiple winding rollers 4 of different lengths can be driven to rotate by rotating multiple telescopic components 6 at the same time, so as to realize the simultaneous winding of fabrics of different widths and improve the efficiency of simultaneously winding fabrics of different widths.

[0023] When the take-up roller 4 finishes winding the fabric and needs to be removed from the base 1, firstly, remove the bolts to disengage it from flange 1 701 and flange 2 702 respectively. Then, remove the screws to disengage it from the threaded holes located on the upper clamping plate 502 and the lower clamping block 501 respectively. Next, rotate the upper clamping plate 502 away from the top of the lower clamping block 501 so that the groove of the upper clamping plate 502 is not in contact with the end of the take-up roller 4. Then, lift the take-up roller 4 with the fabric so that the end of the take-up roller 4 is not in contact with the groove of the lower clamping block 501, so that the clamping assembly 5 does not clamp the end of the take-up roller 4 and remove the take-up roller 4 from the base 1.

[0024] The user can hold and rotate the lead screw 9 clockwise near the right-handed part 902, causing the lead screw 9 to rotate inside the receiving groove 10, and both the left-handed part 901 and the right-handed part 902 to rotate within the receiving groove 10. Because the helical directions of the left-handed part 901 and the right-handed part 902 are opposite, and the two lower clamping blocks 501 are respectively helically connected to the left-handed part 901 and the right-handed part 902, rotating the lead screw 9 clockwise will cause the two lower clamping blocks 501 to move closer to each other, gradually reducing the distance between the two lower clamping blocks 501 for clamping. Install a shorter take-up roller 4, then increase the distance to the take-up roller 4 by rotating the threaded rod 602. By rotating the screw 9 counterclockwise, the two lower clamping blocks 501 can be moved away from each other, so that the distance between the two lower clamping blocks 501 gradually increases, which can be used to clamp a longer take-up roller 4. Then, by rotating the threaded rod 602, the distance to the take-up roller 4 decreases. Thus, according to the different lengths of the take-up roller 4, the distance between the two lower clamping blocks 501 can be adjusted by rotating the screw 9 to install take-up rollers 4 of different lengths.

All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
