[0030] As Figures 1 to 5 shown, the feeding device of the present utility model includes:

[0031] A feeding belt conveyor 71; this feeding belt conveyor is a small belt conveyor; it is used to convey the composite cloth material in the feeding rack to the negative pressure belt conveyor.

[0032] On both sides of the support base on the side close to the feeding belt conveyor, two support frames 73 are provided; they are used to support and fix the feeding rack;

[0033] Feeding side plates 72 are provided on both sides of the said feeding belt conveyor; a T-shaped adjusting plate 74 is provided on the two support frames; the feeding side plates are vertically arranged with respect to the T-shaped adjusting plate to form a feeding rack with a U-shaped cross-section.

[0034] The said T-shaped adjusting plate includes a middle plate 741 and two adjusting support arms 742 arranged in parallel on both sides of the middle plate. Long holes 743 are provided on each of the adjusting support arms; connecting ears 721 are provided at one end of the feeding side plate close to the T-shaped adjusting plate corresponding to the long holes, and screw holes are provided on the connecting ears corresponding to the long holes; adjusting bolts 75 are provided corresponding to each screw hole. By adjusting the bolts, the width between the two feeding side plates can be adjusted to facilitate adapting to composite cloth materials of different specifications.

[0035] An arc-shaped material distribution plate 76 is provided at the lower end of the back of the middle plate. The arc-shaped material distribution plate 76 can be made of a metal material. A friction plate 761 is provided on the material distribution plate corresponding to the feeding belt conveyor. The friction plate 761 can be made of rubber or silica gel to generate sufficient frictional force, so as to ensure that only one material to be printed is output by the feeding belt conveyor in the direction of the negative pressure belt conveyor each time. The height of the arc-shaped material distribution plate 76 can be adjusted by a height adjustment device. As shown in the figure, a connecting block 763 is integrally provided on the back of the middle plate, and a screw hole is provided on the connecting block 763. A bolt 762 passes through the screw hole and extends below the connecting block. The upper end of the arc-shaped material distribution plate 76 is pivotally connected to the lower end of the bolt 762. Rotating the bolt 762, the bolt will move up and down relative to the connecting block, thereby driving the up and down movement of the arc-shaped material distribution plate 76 pivotally connected to the lower end of the bolt 762.

[0036] Figures 6 to 8 The figure shows a schematic structural diagram of a packaging material printing device, including: a support base 1; a negative pressure belt conveyor 2 and a plurality of gantry frames are provided on the support base; a feeding device 7 is provided at the feeding end of the negative pressure belt conveyor. The negative pressure belt conveyor and the feeding belt conveyor can share a numerical control motor and be synchronously controlled through a synchronous belt, or can be respectively controlled by a numerical control motor through a PLC.

[0037] The negative pressure belt conveyor 2 is composed of a negative pressure fan 21, a conveying roller 22, a negative pressure chamber 23, a conveying belt 25 and a numerical control driving motor (not shown in the figure), etc. The negative pressure chamber is arranged between two conveying rollers. The negative pressure chamber is communicated with the negative pressure fan through a pipeline 24. The conveying belt is annularly arranged outside the two conveying rollers where the negative pressure chamber is located. The numerical control driving motor is used to receive the control signal of the programmable logic controller (PLC) to accurately control the rotation speed, so as to control the rotation speed of the conveying roller to achieve the purpose of controlling the running speed of the conveying belt. Vent holes 26 are provided on the conveying belt, and negative pressure holes communicated with the negative pressure chamber are provided at the positions corresponding to the vent holes on the upper surface of the negative pressure chamber. After the negative pressure fan is turned on, a negative pressure can be formed on the conveying belt, so as to facilitate adsorbing the thin packaging material to be printed on the conveying belt, so as to "fix" the packaging material to be printed.

[0038] A nozzle 3 of a plasma surface treatment machine, a UV printing head 4 of a UV inkjet printer and a UV light curing light source 5 are sequentially arranged on the negative pressure belt conveyor. The hosts (not shown in the figure) corresponding to the nozzle 3 of the plasma surface treatment machine and the UV printing head 4 of the UV inkjet printer can be arranged on one side of the support base. The nozzle 3 of the plasma surface treatment machine and the UV printing head 4 are connected to the host through pipelines.

[0039] The plasma surface treatment machine can cause various physical and chemical changes on the surface of the printing material, resulting in etching and roughness, improving the hydrophilicity and adhesiveness of the material surface, so that the inkjet information can be more easily attached to the surface of the printing material.

[0040] The UV inkjet head 4 can use nozzles with diameters of 35um, 45um, and 60um. Preferably, a 35um nozzle is used, which has higher resolution and the ejected patterns are more precise and delicate. The ink used in the UV inkjet printer is water-based UV ink, which is environmentally friendly and pollution-free to the environment. And this ink has no solvent volatilization and will not cause harm to the human body. Subsequently, a UV light curing light source is used to cure it. By using it in combination with the UV ink, a quick-drying effect can be achieved, thus avoiding the ink from seeping into the fabric and making the printed information clearer.

[0041] On the support base, a first gantry 31 is provided corresponding to the nozzle 3 of the plasma surface treatment machine. To facilitate the adjustment of the height of the nozzle, a linear slide is provided on the first gantry, and the nozzle 3 of the plasma surface treatment machine is arranged on the linear slide. On the support base, a second gantry 41 is provided corresponding to the UV inkjet head 4. Similarly, to facilitate the adjustment of the height of the UV inkjet head 4, a linear slide is provided on the second gantry, and the nozzle of the UV inkjet head is arranged on the linear slide. The UV light curing light source 5 is installed on the third gantry 51.

[0042] Furthermore, an optical fiber sensor 6 is provided on the negative pressure belt conveyor 2 to accurately and orderly identify each material and output the identified signal to the programmable logic controller (PLC), thereby controlling the rotation speed of the negative pressure belt conveyor 2 and the operation of the UV inkjet head; effectively avoiding the problem of equipment jamming due to material accumulation. Compared with other sensors, the optical fiber sensor will not generate electric sparks during the signal transmission process, and has higher safety.

[0043] During printing, first place the sheet-like composite cloth material in the feeding rack. Starting the feeding belt conveyor can transport the composite cloth materials one by one to the negative pressure belt conveyor. First, the plasma surface treatment machine is used to improve the hydrophilicity and adhesiveness of the surface of the composite cloth material, so that the inkjet information can be more easily attached to the surface of the printing material. When the composite cloth material passes through the optical fiber sensor, the sensor will transmit the signal to the inkjet printer through the PLC to calculate the time for the composite cloth material to reach the inkjet printer; when the composite cloth material passes through the inkjet printer, the inkjet printer automatically sprays ink, so that the text is printed on the material, and then the printed ink is quickly cured by the UV light curing light source immediately, thereby obtaining clear and complete printed data.
