Negative-pressure adsorption conveying device

Abstract

The invention relates to a negative pressure adsorption conveying device which comprises a hollow shaft, a mounting sliding block, a ventilation pipe and an air suction connector and further comprisesan adsorption position adjusting assembly and an adsorption area adjusting assembly. A wind shielding fan-shaped ring is a non-adsorption area, and the other parts of the wind shielding fan-shaped ring are adsorption areas, and a wind area adjusting block, a wind shielding ring fixing plate and the wind shielding fan-shaped ring are driven to rotate along with a rotating shaft core gland, so thatthe position of the wind shielding fan-shaped ring is adjusted, and therefore, the adsorption position is adjusted. When a hand wheel is rotated, a first gear is driven to rotate through a connectingrod, the first gear drives a second gear and a first screw to rotate, the first screw rotates to drive a first fan-shaped piece to move front and back, the adsorption area can be adjusted through front-back movement of the first fan-shaped piece, and meanwhile, the adsorption position can be adjusted, and the negative pressure adsorption conveying device can adsorb different materials. The negative-pressure adsorption conveying device is skillful in structural design and compact in structure and makes full use of an internal space of a hollow shaft. Meanwhile, the negative-pressure adsorptionconveying device is simple in structure and convenient.

Description

technical field [0001] The invention relates to the technical field of die-cutting machines, in particular to a negative pressure adsorption conveying device. Background technique [0002] In the die-cutting machine, the negative pressure adsorption conveying device is generally used to absorb the material, so that the material can be attached to the lower printing material, thereby reducing the difficulty of conveying the material. The negative pressure adsorption transmission device generally includes a hollow shaft, a mounting slider, a ventilation pipe and a suction joint, and the hollow shaft includes a shaft sleeve and shaft heads fixed at both ends of the shaft sleeve. On the head, it is installed on the frame of the die-cutting machine through the installation slider. There are ventilation holes on the circumference of the shaft sleeve, and a ventilation pipe is provided at one end of the hollow shaft. A suction joint is connected to the outside of the ventilation pi...

AI Technical Summary

Problems solved by technology

In actual use, the negative pressure adsorption conveying device needs to adsorb different materials. Since the vacuum degree provided by the negative pressure fan is fixed, different materials need to be matched with different negative pressure fans so that they can be stably adsorbed to negative pressure. On the adsorption conveying device, resulting in poor flexibility of the negative pressure adsorption conveying device, and in the replacement process, time-consuming and labor-intensive, affecting the normal production of the production line
