Description

Escape door fire protection coating spraying equipment

Technical Field

The invention belongs to the technical field of spraying equipment, and particularly relates to escape door fireproof coating spraying equipment.

Background

The escape door is used for evacuating people and facilitating escape, and has higher requirements on firmness, opening convenience and flame retardance of the door; in the process of producing the escape door, a thicker fireproof coating needs to be sprayed, but the thicker fireproof coating is sprayed once, so that the coating is easy to crack, the fireproof and decorative effects are reduced, and even the product is scrapped, so that the coating is usually sprayed for multiple times; when the existing spraying equipment is used, corresponding stirring mechanisms are mostly used and are synchronously used with the spraying equipment, so that the spraying equipment can continuously and uninterruptedly spray.

For example, authorization publication number: the patent of CN209866412U discloses a surface spraying device for the production of a civil air defense door, which comprises a bottom plate, a fixed frame, a first screw, a sliding sleeve, a chain, an air outlet pipe and an air inlet pipe; the stirring mechanism is arranged, so that the spraying materials are favorably and uniformly stirred, the civil air defense door is conveniently and directly sprayed, the trouble of filling the spraying materials back and forth is avoided, and the time is saved; the filter shell is arranged, so that toxic gas generated in the spraying process can be absorbed, and the influence on the body health of workers is avoided; the driving mechanism is arranged, so that the spraying mechanism can be driven back and forth automatically, and the trouble of manual spraying is avoided; the spraying mechanism is arranged, so that the spraying operation of the civil air defense door is facilitated, meanwhile, the rotating shell swings left and right in the spraying process, the uniform spraying of the civil air defense door is facilitated, the phenomenon that the coating is cracked easily due to the fact that thick fireproof coating is sprayed at one time is avoided, the fireproof and decorative effects are reduced, and even products are scrapped; in addition, when the air-defense door is used, the air-defense door is placed between the air cylinders, the second motor is controlled, and the motor shaft of the second motor drives the first screw rod to rotate, so that the moving seat moves in the left-right direction, and the moving seat is adjusted according to the size of the air-defense door, so that the air-defense door is fixed.

However, the surface spraying device for the civil air defense door production still has the defects that: 1. the stirring mechanism is an independent rotating shaft matched with fan blades to stir the coating, and the structure is simple; in the spraying process of the civil air defense door, in order to improve the market of the sustainable work of spraying equipment, a large amount of paint is often needed for spraying; therefore, when the stirring shell is small, the coating needs to be added frequently, and the normal use of the spraying equipment is influenced; however, when the stirring shell is large and the stirring materials are more, the single rotating shaft is matched with the fan blades, so that when the stirring is carried out, the materials at all places in the stirring shell can not be effectively and completely stirred, and particularly, the stirring effect of the coating at the edge part of the stirring shell is worse, and the spraying effect is influenced.

2. When the device is used, the civil air defense door needs to be manually placed in place, and then the civil air defense door is fixed through the movable seat, so that the operation is troublesome; when the device is fixed, only one direction of the civil air defense door can be fixed through the movable seat, and the three-dimensional space of the civil air defense door cannot be effectively fixed, so that the spraying structure is easy to cause waste of spraying materials when being sprayed; the space of the spraying cavity is limited, so that the carrying operation of personnel is inconvenient; and after the spraying of people's air defense door, the air quality of spraying intracavity is relatively poor, if personnel are close to the transport, can inhale a large amount of harmful gas undoubtedly, influences personnel's health.
