[0004] The above-mentioned prior art solutions have the following defects: when the digital printer is in use, if the fabric is thick, it can only print on the surface of the thick fabric. After printing, the bottom fabric is still not printed with the pattern, resulting in incomplete dyeing. Summary of the invention

[0005] In view of the shortcomings of the prior art, the object of the present invention is to provide a digital composite printing machine capable of printing thick fabrics through the bottom.

[0009] By adopting the above technical solution, the cloth enters the printing machine through the first section cloth feeding system and the second section cloth feeding system, and then the cloth is transported to the cloth conveyor belt. The cloth conveyor belt is covered with a layer of glue by the first gluing system, and the cloth is attached to the cloth conveyor belt by the glue. When wet printing is required, the digital glue is applied to the cloth through the scraper mechanism, and the digital printing machine is used to digitally print the small area of ​​different colors on the cloth. The cloth continues to be conveyed. When it reaches the bottom of the magnetic rod body, the absorption seat puts down the magnetic rod body, and the magnetic seat absorbs the magnetic rod body. The magnetic seat slides left and right through the sliding mechanism, driving the magnetic rod body to roll on the cloth, thereby printing a large area of ​​color on the cloth. When dry printing, the cloth can be flattened by the scraper, and the digital printing machine is used to digitally print the small area of ​​different colors on the cloth. The large area of ​​the same color is dyed by the magnetic rod body rolling on the magnetic seat. Finally, the glue on the cloth conveyor belt is removed by the glue washing device.

[0010] In a preferred example, the present invention can be further configured as follows: the scraper mechanism includes a second fixed arm fixed on the frame, the second fixed arm is slidably connected to a second fixed seat on both sides, a second driving cylinder with a piston rod directed downward is arranged on both sides of the second fixed seat, and a scraper body is arranged on the piston rod of the second driving cylinder.

[0011] By adopting the above technical solution, the piston rod of the second driving cylinder extends downward to press the scraper body on the cloth, and the second fixed seat slides on the second fixed wall to scrape and dye the cloth; at the same time, the scraper body can also scrape the cloth to flatten the cloth.

[0012] In a preferred example, the present invention can be further configured as follows: the sliding mechanism includes a first nut below the magnetic base, the first nut is internally threadedly connected to a first screw rod rotatably connected to the frame, and the first screw rod is coaxially connected to a first servo motor.

[0013] By adopting the above technical solution, the first servo motor rotates, driving the first screw to rotate, the first nut converts the rotational force of the first screw into linear motion, and the first nut drives the magnetic base to move along the direction perpendicular to the fabric transmission direction, so that it can cooperate with the magnetic rod above, roll on the fabric, and perform printing.

[0016] In a preferred example, the present invention can be further configured as follows: the first section of the cloth feeding system includes a placement seat for placing the raw cloth roll, a first cloth feeding roller and a second cloth feeding roller rotatably connected to the frame are arranged above the placement seat, the first cloth feeding roller and the second cloth feeding roller are in contact with each other, the first cloth feeding roller is coaxially connected to the cloth feeding motor, a recovery chamber is arranged below the second cloth feeding roller, and the recovery chamber includes an arc-shaped recovery plate and an infrared sensor located on the arc-shaped recovery plate.

[0017] By adopting the above technical solution, the first cloth feeding roller is driven to rotate by the cloth feeding motor, and the cloth is driven into the recovery chamber, where the cloth is stacked. Because some cloth is elastic, pulling the cloth will cause the cloth to be too tight, which is not conducive to the dyeing of the cloth. The cloth can restore its elasticity by passing through the recovery chamber. The infrared sensor can monitor whether there is cloth stacking in the recovery chamber.

[0018] In a preferred example, the present invention can be further configured as follows: the second-section cloth feeding system includes a cloth feeding box, a third cloth feeding roller and a fourth cloth feeding roller are rotatably connected in parallel at the upper portion of the cloth feeding box, a first unrolling roller is rotatably connected in the middle section of the cloth feeding box, a second unrolling roller, a third unrolling roller and a fourth unrolling roller are arranged at the bottom of the cloth feeding box, a floating wheel abutting against the cloth conveyor belt is arranged at the bottom of the cloth feeding box, and the floating wheel is horizontally movably connected to the cloth feeding box.

[0019] By adopting the above technical solution, the third cloth feeding roller and the fourth cloth feeding roller can clamp the cloth, so that the cloth can be stably transferred into the cloth box, and then the first unfolding roller, the second unfolding roller, the third unfolding roller and the fourth unfolding roller can fully unfold the cloth to reduce the wrinkles of the cloth. The cloth conveyor belt conveys forward for a distance, and the floating wheel conveys forward with the cloth conveyor belt. After the cloth conveyor belt stops, the floating wheel moves away from the conveying direction, and the subsequent cloth is pressed flatly on the cloth conveyor belt to achieve the purpose of leveling.

[0020] In a preferred example, the present invention can be further configured as follows: slot-type photoelectric sensors are provided on both sides of the third unwinding roller.

[0021] By adopting the above technical solution, the position of the cloth during the transmission process can be adjusted to achieve better positioning, thereby reducing the left-right shaking of the cloth and causing inaccurate printing and dyeing.

A recovery chamber 25 is arranged below the second cloth feed roller 23. The recovery chamber 25 includes an arc-shaped recovery plate 251 and an infrared sensor 252 located on the arc-shaped recovery plate 251. Because some cloths are elastic, when the cloths are transported to the printing machine, the cloths will be pulled, causing the cloths to be too tight, which is not conducive to the dyeing of the cloths. By stacking the cloths on the arc-shaped recovery plate 251, the cloths can restore their elasticity, and the infrared sensor 252 can monitor whether there is cloth stacked in the recovery chamber 25.

The center of the floating wheel 38 is coaxially connected to the piston rod of the floating cylinder 381. The floating cylinder 381 is arranged horizontally to push the floating wheel 38 to move left and right. The cloth conveyor belt 4 is conveyed forward for a distance, and the floating wheel 38 is conveyed forward along with the cloth conveyor belt 4. After the cloth conveyor belt 4 stops, the piston rod pushed by the floating cylinder 381 extends, and the floating wheel 38 moves away from the conveying direction, pressing the subsequent cloth flatly on the cloth conveyor belt 4 to achieve the purpose of leveling. In this embodiment, both sides of the third unfolding roller 36 are provided with slot-type photoelectric sensors 361, which can adjust the position of the cloth during the conveying process, perform better positioning, and reduce the purpose of inaccurate printing and dyeing caused by the left and right shaking of the cloth.

The absorption seat 74 absorbs a magnetic bar body 75 through electromagnetic force. A magnetic seat 76 is arranged below the cloth conveyor belt 4, and the magnetic seat 76 is slidably connected to the frame 1 through a sliding mechanism 77.

[0046] The implementation principle of this embodiment is as follows: the first cloth feed roller 22 and the second cloth feed roller 23 clamp the cloth, and the cloth feed motor 24 drives the first cloth feed roller 22 to rotate and transport the cloth to the printing machine. A recovery chamber 25 is arranged below the second cloth feed roller 23, and the recovery chamber 25 includes an arc-shaped recovery plate 251 and an infrared sensor 252 located on the arc-shaped recovery plate 251. Because some cloths are elastic, when the cloths are transported to the printing machine, the cloths will be pulled, causing the cloths to be too tight, which is not conducive to the dyeing of the cloths.
