DETAILED DESCRIPTION

[0030] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0031] Reference Figure 1 The utility model provides an embodiment: a feeding device for digital printing, including a base 1, a printing machine 2 is fixedly connected to the upper surface of the base 1, a roller 3 is arranged on the right side of the upper surface of the base 1, and a guide roller 4 is arranged on the right side of the printing machine 2. The roller 3 and the guide roller 4 are both installed on the base 1 through a mounting frame, and the roller 3 and the guide roller 4 can both rotate inside the mounting frame. The roller 3 is used for placing the fabric drum and releasing the fabric. The guide roller 4 can guide and limit the movement of the fabric, so that the fabric can horizontally enter the interior of the printing machine 2 for printing operations.

[0032] Reference Figure 2-Figure 3 A U-shaped frame 5 is fixedly connected to the center of the upper surface of the base 1, and a limiting roller 6 is rotatably connected to the inner center of the U-shaped frame 5. An absorbent cloth 7 is arranged above the limiting roller 6, and the upper surface of the absorbent cloth 7 fits with the bottom surface of the guide roller 4, and the bottom surface of the absorbent cloth 7 fits with the upper surface of the limiting roller 6. The limiting roller 6 can limit the absorbent cloth 7 placed on the upper end thereof, so that the absorbent cloth 7 can fit the bottom end of the guide roller 4. When the guide roller 4 rotates, the absorbent cloth 7 can absorb the moisture adhered to the guide roller 4. A winding unit is arranged on the right side of the U-shaped frame 5, and the winding unit includes a rotating shaft 71, which is rotatably connected to the right side of the inner part of the U-shaped frame 5. A winding roller 72 is fixedly connected to the outer side of the rotating shaft 71, and the rotating shaft 71 can support and limit the rotation of the winding roller 72. A torsion spring 73 is fixedly connected to the front end of the winding roller 72, and the torsion spring 73 is sleeved on The front end of the torsion spring 73 is fixedly connected to the front inner wall surface of the U-shaped frame 5 on the outside of the rotating shaft 71. When the winding roller 72 rotates, the torsion spring 73 can be driven to rotate, so that the torsion spring 73 generates a torque. A winding rope 74 is wound around the outer surface of the winding roller 72. The right end of the winding rope 74 is fixedly connected to the outer surface of the winding roller 72. When the winding rope 74 moves to the left, the winding roller 72 can be pulled to rotate the winding roller 72. The left end of the winding rope 74 is fixedly connected to the right end of the absorbent cloth 7. When the absorbent cloth 7 is forced to move to the left, the winding roller 72 can be pulled by the winding rope 74, thereby causing the torsion spring 73 to rotate and generate torque. When the tension on the absorbent cloth 7 disappears, the winding rope 74 can be rewound around the outside of the winding roller 72 under the action of the torque of the torsion spring 73, thereby causing the absorbent cloth 7 to move to the right and reset.

[0033] A dehumidification unit is provided below the limiting roller 6, and the dehumidification unit includes an electric heating rod 81 and a motor 82. The electric heating rod 81 is fixedly connected to the right side of the inside of the U-shaped frame 5, and the left end of the absorbent cloth 7 is wound around the outside of the electric heating rod 81. When the electric heating rod 81 is powered on, it can generate heat to heat the absorbent cloth 7 passing through, thereby accelerating the drying of the absorbent cloth 7. The motor 82 is fixedly connected to the front surface of the U-shaped frame 5, and the rear output end of the motor 82 runs through the U-shaped frame 5. The rear output end of the motor 82 is fixedly connected to The rotating rod 83 and the motor 82 can drive the rotating rod 83 to rotate when they are started. The rear end of the rotating rod 83 is rotatably connected to the rear inner wall surface of the U-shaped frame 5. A connecting rope 84 is wound around the outer side of the rotating rod 83. When the rotating rod 83 rotates, the connecting rope 84 can be driven to be rolled up or released. The left end of the connecting rope 84 is fixedly connected to the left end of the absorbent cloth 7, and the right end of the connecting rope 84 is fixedly connected to the outer surface of the rotating rod 83. When the rotating rod 83 rotates, the connecting rope 84 can be rolled up and the absorbent cloth 7 can be pulled.

[0034] When the wet cloth is fed through the guide roller 4, a small amount of part of the cloth will be squeezed out and adhere to the guide roller 4. As the guide roller 4 rotates, the adhered moisture will be absorbed by the absorbent cloth 7 to avoid the moisture squeezed out of the cloth that passes first adhering to the guide roller 4, causing it to be absorbed by the cloth that passes later, resulting in excessive humidity inside the cloth that passes later and affecting the printing effect. A humidity detector can be set on the outside of the limiting roller 6. When it is detected that the humidity at the bottom of the absorbent cloth 7 is too high, it means that the part of the absorbent cloth 7 located above the limiting roller 6 has been full of moisture. At this time, the motor 82 can be started to pull the absorbent cloth 7, so that the part of the absorbent cloth 7 located at the bottom of the guide roller 4 can be replaced, so that the entire absorbent cloth 7 can be used. When the absorbent cloth 7 is pulled to the outside of the electric heating rod 81, the electric heating rod 81 can be energized to heat the absorbent cloth 7 to accelerate the drying of the absorbent cloth 7, so that the absorbent cloth 7 can be reused.

[0035] When the absorbent cloth 7 is pulled to the left side of the limiting roller 6 as a whole, the motor 82 can be started to release the connecting rope 84, thereby releasing the pulling on the absorbent cloth 7 and releasing the rotation of the torsion spring 73. At this time, the winding rope 74 can be rewound around the outside of the winding roller 72 under the action of the torque of the torsion spring 73, thereby pulling the absorbent cloth 7 to the right, so that the absorbent cloth 7 can continue to be used after drying. At the same time, in the process of the absorbent cloth 7 moving to the left, the torsion spring 73 generates a torque that pulls the absorbent cloth 7, so that the absorbent cloth 7 can be squeezed between the electric heating rod 81, squeeze out the moisture in the absorbent cloth 7, and further accelerate the drying speed of the absorbent cloth 7.

[0036] Reference Figure 3-Figure 4A water collecting box 9 is arranged on the left side of the inner bottom surface of the U-shaped frame 5. The water collecting box 9 is located below the electric heating rod 81. The water squeezed out of the absorbent cloth 7 will drip downward into the water collecting box 9 for collection. An inclined plate 10 is fixedly connected to the inner right side of the water collecting box 9. The inclined plate 10 is arranged in an inclined structure downward to the left. An inclined groove 11 is arranged on the left side of the inner bottom surface of the water collecting box 9. After the water droplets enter the water collecting box 9, they can slide down to the left along the inclined surface of the inclined plate 10 and enter the inclined groove 11. 1, the front end of the chute 11 is inclined downward, and a water outlet pipe 12 is fixedly connected to the left surface of the water collecting box 9. The inside of the water collecting box 9 is connected with the outside through the water outlet pipe 12. When water drops enter the chute 11, they can flow completely into the water outlet pipe 12 along the inclined surface of the chute 11. The water outlet pipe 12 can be connected to an external water pipe to guide the dripping water to the outside, so as to prevent the water drops from directly dripping under the absorbent cloth 7, causing the environment to be humid and affecting the heating and drying effect of the absorbent cloth 7.

[0037] Working principle: first place the cloth roll on the outside of the drum 3, then guide the end of the cloth through the guide roller 4 and put it into the printing machine 2 for printing. In order to improve the affinity between the ink and the cloth and make the ink easier to penetrate the cloth, the cloth will be wetted first. When the wet cloth passes through the guide roller 4, a small amount of water will be squeezed out onto the guide roller 4. As the guide roller 4 rotates, the adhered water will be absorbed by the absorbent cloth 7 set below. When the absorbent cloth 7 at the limit roller 6 absorbs more water and the water absorption performance decreases, it can be The motor 82 is started to drive the absorbent cloth 7 to move to the left and pass through the electric heating rod 81, so that the position of the absorbent cloth 7 above the limiting roller 6 is replaced, so that the entire absorbent cloth 7 can be utilized, and at the same time, the electric heating rod 81 can be started to heat and dry the absorbent cloth 7, so that the absorbent cloth 7 can be adsorbed for utilization. When the absorbent cloth 7 completely passes through the limiting roller 6, the motor 82 can be started again to release the absorbent cloth 7, so that the absorbent cloth 7 is moved and reset under the action of the winding unit, thereby realizing the reuse of the absorbent cloth 7.
