[0002] Digital printing equipment is an industry term for large-format printers. It mainly uses water-based disperse inks, which are printed on transfer paper and then transferred to fabric through high temperature. This involves the printing alignment device of a dual-ink digital printing machine.

[0003] Currently, Chinese patent publication number CN220700728U discloses a printing alignment device for a digital printing machine, including a fixed platform. An alignment platform is slidably mounted on the upper side wall of the fixed platform, and an alignment mechanism is provided on the alignment platform. A moving adjustment mechanism is provided on the side wall of the alignment platform. A right-angle plate is fixedly connected to the upper side wall of the fixed platform, and a hydraulic cylinder is fixedly connected to the upper side wall of the right-angle plate. The drive end of the hydraulic cylinder passes through the upper side wall of the right-angle plate and is fixedly connected to the digital printing machine body. This invention solves the problem that existing digital printing machines cannot position the material during normal printing operations, leading to printing errors and inconvenience. It also allows for adjustment of the printing position of the material, improving the practicality of the device.

[0004] However, during the implementation of the above technical solution, at least the following technical problems were found: The above solution can drive the rotating rod to rotate through the motor, which can push the lifting plate to move down, so that each right-angle pressure plate can move down synchronously to achieve the pressing and fixing of the material. However, the distance between the right-angle pressure plates is fixed and cannot effectively fix materials of different sizes. For this reason, we provide a precise alignment device for PU transfer printing of spring spun fabric. Utility Model Content

[0024] This application embodiment provides a precise alignment device for PU transfer printing on spring spun fabric. (By setting a fixing component, the distance between the two support plates is adjusted according to the fabric size. The bidirectional screw is rotated, and the support plates move closer or further apart under the restriction of the limiting slider and the slide groove, so as to fix fabrics of different sizes. Then, the cylinder is activated, and the moving end of the cylinder drives the connecting plate to move downward. The connecting plate drives the support plate and the pressure plate to move downward until the rubber ball is in close contact with the fabric, thus fixing the fabric.)

[0025] Example 1

[0026] The technical solution in this application embodiment effectively solves the problem that the above-mentioned solution can drive the rotating rod to rotate via a motor, which can push the lifting plate downward, thus enabling each right-angle pressure plate to move downward synchronously to achieve material clamping and fixing. However, the distance between the right-angle pressure plates is fixed, which cannot effectively fix materials of different sizes. The overall idea is as follows:

[0027] like Figures 1 to 3To address the problems existing in the prior art, this utility model provides a precise alignment device for PU transfer printing on spring spun fabrics, including a processing base 1.

A bracket 103 is fixedly connected to the top of the processing base 1. A hydraulic cylinder 3 is fixedly installed at the middle of the top of the bracket 103. The movable end of the hydraulic cylinder 3 passes through the bracket 103 and is fixedly installed on the printing machine body 4. A placement box 5 is provided below the printing machine body 4. Fixing components 6 are provided inside and above the placement box 5. Movable grooves 51 are opened on the upper sides of the placement box 5. Two snap-fit ​​grooves 52 are symmetrically opened on the top of the placement box 5. Two sliders 21 are fixedly connected to the bottom of the placement box 5. A slide rail 2 corresponding to the two sliders 21 is fixedly installed on the top of the processing base 1. The fixing components 6 include a cylinder 61, a connecting plate 62, and a limiting slider. 63. Support plate 64, slide groove 65, pressure plate 66, rubber ball 67, guide rod 68, sliding block 69, and double screw 60. Cylinder 61 is fixedly installed inside the bottom of the placement box 5. The output end of cylinder 61 is fixedly connected to connecting plate 62. Support plates 64 are provided on both sides of the top of connecting plate 62. Pressure plate 66 is fixedly connected to one side of the top of support plate 64. Multiple rubber balls 67 are fixedly connected to the bottom of pressure plate 66.

Support plate 64 is slidably engaged in the inside of engaging groove 52.

[0028] Working principle: In use, the fabric is placed on top of the placement box 5. First, the distance between the two support plates 64 is adjusted according to the fabric size. The bidirectional screw 60 is rotated, and the support plates 64 move closer or further apart under the restriction of the limit slider 63 and the slide groove 65, so as to fix the fabric of different sizes. Then, the cylinder 61 is started. The moving end of the cylinder 61 drives the connecting plate 62 to move downward. The connecting plate 62 drives the support plate 64 and the pressure plate 66 to move downward until the rubber ball 67 is in close contact with the fabric, thus fixing the fabric. During this process, the sliding block 69 slides along the direction of the guide rod 68. Through the control panel 102, the hydraulic cylinder 3 drives the printing machine body 4 to move downward to print on the fabric. The placement box 5 can be moved by an external drive. The slide rail 2 and the slider 21 enhance the stability of the placement box 5 during movement.
