[0001] The invention relates to the technical field of printing machines, in particular to a printing alignment device of a printing machine. Background Art

[0002] A printing machine is suitable for printing on a variety of materials. After modification, the application range of the printing machine is wider and is no longer limited to paper printing. In the production process of clothing, scarves, etc., it is necessary to print decorative patterns such as patterns on fabrics or semi-finished products. Printing is a commonly used method and a printing machine is needed for printing; digital printing is printing using digital technology. Digital printing technology is a high-tech product that integrates machinery, computer, electronic information technology and has gradually formed with the continuous development of computer technology. The digital printing machine is also called a universal printer and is widely used in the personalized customization industry of T-shirts.

[0003] Before printing on a T-shirt, the digital printing machine needs to keep the T-shirt flat to ensure that there are no creases or indentations on the T-shirt. Therefore, when creases and indentations appear on the T-shirt, it is necessary to perform a series of flattening treatments such as stretching and ironing on the T-shirt before fixing it. This process involves many steps and has low efficiency. Summary of the invention

[0004] 1. Technical issues to be solved

[0005] In view of the shortcomings of the prior art, the present invention provides a printing alignment device for a printing machine, which solves the problem that when creases and indentations appear on the T-shirt, the T-shirt needs to be subjected to a series of flattening treatments such as stretching and ironing before being fixed, resulting in multiple processing procedures and low efficiency.

[0006] (II) Technical solution

[0007] To achieve the above purpose, the present invention is implemented through the following technical solutions: a printing alignment device of a printing machine, comprising a platform and a slide rail, the two sides below the platform are fixedly connected to the slide rail, the upper end of the platform is fixedly connected to a handle, the upper middle part of the platform is fixedly connected to a connecting platform, the upper middle part of the connecting platform is fixedly connected to a working table, both sides of the upper ends of the working table are provided with cross cursors, and infrared generators are provided below the four cross cursors;

[0008] On both sides above the platform, there are sliding seats connected in a sliding manner. At both ends below the two sliding seats, there are limit sliders fixedly connected. At positions corresponding to the four limit sliders above the platform, there are chute grooves opened. In the middle of both sides above the platform, there are strip holes opened. In the middle of the lower part of both sliding seats, there are lead screw nuts fixedly connected. On both sides of the middle part of the lower part inside the platform, there are two limit seats fixedly connected. Inside the platform, there is a transmission shaft rotatably connected through the limit seats. At both ends of the transmission shaft, there are driving lead screws fixedly connected. In the middle of the transmission shaft, there is a worm and worm gear mechanism. At a position corresponding to the worm and worm gear mechanism above the inside of the platform, there is a transmission shaft rotatably connected. One end of the transmission shaft far away from the worm and worm gear mechanism passes through the platform and is fixedly connected with a hand wheel. When rotating the hand wheel, by the combined transmission of the transmission shaft, the worm and worm gear mechanism and the linkage shaft, through the cooperation of the driving lead screw and the lead screw nut, drive the sliding seats and the support platforms on both sides to move synchronously;

[0009] On both sides above the connecting platform, there are pressing table surfaces arranged. Above the two sliding seats, there are support platforms fixedly connected. At positions corresponding to the pressing table surfaces on one side of the two support platforms close to the connecting platform, there are tight material seats fixedly connected. At one end close to the pressing table surface below the two tight material seats, there are lower roller grooves opened. Inside the two lower roller grooves, there are tight material rollers rotatably connected. Inside the two tight material seats, at one end close to the lower roller grooves below, there are multiple top roller wheels rotatably connected. When the support platform moves, the tight material seats and the tight material rollers can enter above the pressing table surface. Use the tight material rollers to press the T-shirts above the pressing table surface. When the tight material seats continue to move, due to the pressure of the tight material rollers, the T-shirts are fixed above the pressing table surface. And since the tight material rollers can rotate, they can roll relative to the T-shirts. Therefore, the T-shirts can be stretched through the tight material seats without affecting the fixation of the T-shirts, eliminating the creases and indentations of the T-shirts on the workbench, and reducing the leveling treatment operation;

[0010] Above the two support platforms, there are multiple limit telescopic rods fixedly connected at equal intervals above the tight material seats. Above the two tight material seats, there are pressing seats slidably connected. On one side of the two pressing seats close to the workbench, there are two roller shaft grooves opened. Inside the four roller shaft grooves, there are pressing rollers rotatably connected. When the support platform moves, the spring pressure can be used to balance the pressure on the T-shirts on both sides of the workbench through the pressing rollers, preventing new wrinkles from being generated due to uneven friction during the stretching process. With the flattening effect of the pressing rollers themselves, the leveling ability of the device can be improved.

[0011] Preferably, the limit telescopic rod includes a limit sleeve, a compression spring, a sliding plate and a sliding rod. Inside the limit sleeve, there is a compression spring arranged. Inside the limit sleeve, at one end close to the workbench, there is a sliding plate slidably connected. One end of the sliding plate far away from the compression spring is fixedly connected with a sliding rod. One end of the sliding rod far away from the sliding plate is fixedly connected with the pressing seat.

[0012] Preferably, the thread directions of the two driving screws are opposite, and the two driving screws both pass through the corresponding screw nuts and cooperate with the corresponding screw nut threads, so that the two screw nuts can move synchronously.

[0013] Preferably, the bottoms of the two sliding seats are slidably connected to the corresponding sliding grooves through two limiting sliding blocks.

[0014] Preferably, the positions of the two pressing seats correspond to the positions of the workbench.

[0015] Preferably, the number and positions of the plurality of top rollers correspond to the positions of the limiting telescopic rods.

[0016] Preferably, the hand wheel is transmission-connected to the linkage shaft via a transmission shaft and a worm gear mechanism.

[0017] Working principle: When the present invention is used, the material tightening seats and material tightening rollers arranged on both sides of the workbench cooperate with the material pressing table surface. When the hand wheel is turned, the transmission shaft, the worm gear mechanism and the linkage shaft are used to cooperate with the driving screw and the screw nut to drive the sliding seats and the support table on both sides to move synchronously. When the support table moves, the material tightening seat and the material tightening roller can enter the upper part of the material pressing table surface, and the material tightening roller is used to press the T-shirt above the material pressing table surface. When the material tightening seat continues to move, the pressure of the material tightening roller fixes the T-shirt above the material pressing table surface. Since the material tightening roller can rotate, it can roll relative to the T-shirt. Therefore, the T-shirt can be fixed by the material tightening seat without affecting the fixation of the T-shirt The t-shirt can be stretched to eliminate creases and indentations on the T-shirt on the workbench, thereby reducing the number of leveling operations, reducing the processing flow, and improving the processing efficiency. The pressing seat provided in the present invention, in conjunction with the limiting telescopic rod and the pressing roller, can use the spring pressure to balance the pressure of the T-shirts on both sides of the workbench through the pressing roller when the support table moves, thereby preventing new wrinkles from being generated due to uneven friction during the stretching process. In conjunction with the flattening effect of the pressing roller itself, the leveling ability of the device can be improved. In addition, the multiple top rollers provided in the present invention can prevent the deformation of the tightening roller from causing pressure imbalance, thereby causing uneven stretching, without affecting the rotation of the tightening roller, thereby further improving the leveling ability of the device.
