Description

Technical Field

[0001] The invention relates to a high-speed inkjet printer, in particular to an automatic compensation structure for air volume and air pressure of an inkjet printer platform. Background Art

[0002] The suction plate of the inkjet conveying platform of an ordinary high-speed inkjet printer is generally made of sheet metal. Only one row of ventilation holes is processed on the suction plate. When the machine is running, the belt holes on the transmission belt and the ventilation holes on the sheet metal will sometimes be connected and sometimes not. The adsorption force keeps changing and fluctuating. The paper on the transmission belt cannot be firmly adsorbed and becomes loose. The flatness of the conveyed paper decreases, and the stability is poor. The wind pressure and air volume at the suction point cannot be automatically compensated, resulting in poor suction effect, low inkjet efficiency, poor accuracy, and a high defective rate. Summary of the invention

[0004] The present invention solves the above-mentioned problem by adopting the following technical solution:

[0005] A high-speed inkjet printer coding platform air volume and pressure automatic compensation structure comprises an air suction plate and a fan, the air suction plate is integrally mounted on a bracket and connected to the bracket as a whole, a transmission belt is arranged at the upper end of the air suction plate, the transmission belt is provided with belt holes for ventilation and adsorbing paper, a plurality of air suction boxes are arranged at intervals along the transmission direction of the transmission belt at the lower end of the air suction plate, each air suction box is connected to the fan through an air duct, a plurality of air slots are arranged at intervals corresponding to each air suction box on the air suction plate, the air slots are arranged along the transmission direction of the transmission belt, a row of ventilation holes are arranged at the bottom of each air slot, and the air slot is connected to the inside of the air suction box through the ventilation holes.

[0006] Compared with the prior art, the present invention adopting the above technical solution has the following outstanding features:

[0007] When the whole machine runs at high speed, the machine has high stability. The whole suction plate of the platform is processed with wind slots, and the bottom of the wind slots is processed with ventilation holes, so that a constant air volume and air pressure are formed on the suction transmission belt. The conveyed paper on the platform has high flatness and paper adsorption is rapid, which provides good coding conditions for the high-speed inkjet printhead, greatly improves the speed and accuracy of coding, and reduces the scrap rate of the coding process.

[0008] Preferably, a further technical solution of the present invention is:

[0009] The suction plate is also provided with mounting grooves for connecting the connecting end plates on both sides of the suction box. The mounting grooves are arranged along the transmission direction of the transmission belt. The bottom of the mounting grooves is connected and fixed to the connecting end plates of the suction box by screws. Ventilation gaps are arranged between the mounting grooves and adjacent air grooves. The ventilation gaps are provided to realize automatic compensation of air volume and pressure in the mounting grooves, thereby improving the adsorption capacity of paper on the transmission belt and the stability of the machine.

[0010] The ventilation notch is arranged obliquely along the transmission direction of the transmission belt, and air is supplied along the transmission direction with small resistance and strong adsorption force.

[0011] The installation slot is connected with the wind slot at the head and tail, so the ventilation effect is good and the wind pressure is stable. BRIEF DESCRIPTION OF THE DRAWINGS
