Ear belt feeding device and method for cup-shaped mask production

Abstract

The invention relates to the technical field of mask machines. The invention discloses an ear belt feeding device for cup-shaped mask production. The ear belt feeding device comprises a feeding assembly, an installation frame, a moving frame, a moving air cylinder, a rotating motor, a rotating shaft, a gear set, a winding disc, a rope clamping assembly and a rope cutting assembly. The feeding assembly is used for sending out the ear belt rope; the movable frame is movably connected to the installation platform through a sliding rail, the movable air cylinder is arranged on the installation frame, and the telescopic end of the movable air cylinder is connected with the movable frame. The rotating motor is installed on the moving frame, and the rotating shaft is hinged to the moving frame. The center of the winding disc is fixed at the shaft end of the rotating shaft; the rope clamping assembly and the rope cutting assembly are installed on the winding disc. The device has the advantagesof rotary ear band winding, compact structure, high band winding efficiency, simultaneous processing of two sides of the cup-shaped mask and small nailing impact force.

Description

technical field [0001] The invention relates to the technical field of mask machines, in particular to an earband feeding device for the production of cup-shaped masks. Background technique [0002] Mask is a kind of health protective equipment used to protect the respiratory system from smog, exhaust gas, dust, germs, etc. Generally refers to the device worn on the mouth and nose to filter the air entering the mouth and nose, so as to block harmful gases, odors, and droplets from entering and exiting the wearer's mouth and nose. Masks have a certain filtering effect on the air entering the lungs. When respiratory infectious diseases are prevalent, wearing a mask has a very good effect when working in a polluted environment such as dust. The flat masks in the prior art generally have ear straps welded at both ends, and each ear strap is welded to the upper and lower ends of the mask respectively. In some usage occasions, it is necessary to use movable ring-shaped ear straps...

AI Technical Summary

Problems solved by technology

[0004] There are the following problems in the prior art: 1. The feeding speed of the ear straps is slow, and the swinging ear strap method will interfere with the spatial structure, so it is difficult to feed materials on both sides at the same time; 2. The two processes of ear strap cutting and nailing are carried out in one Simultaneous processing of the stations leads to a huge mechanism, error-prone movement links, and process waiting, which makes it difficult to increase the processing speed; the ear straps of the three-dimensional cup-shaped masks are prone to misalignment during the transportation process; 3. The chain conveying jig is not accurate
