Heat-sealing overlock device for mask processing

Abstract

The invention discloses a heat-sealing overlock device for mask processing, and relates to the technical field of mask processing. The heat-sealing overlock device comprises a rack, heat-sealing frames and positioning and leveling mechanisms. A conveying mechanism is arranged at the inner upper part of the rack, a support pillar is fixedly arranged at the upper part of the rack, and a mounting topplate is fixedly arranged at the upper part of the support pillar. An electric push rod is arranged at the lower part of the mounting top plate, and a lifting plate is fixedly arranged at the lower part of the electric push rod. The heat-sealing frames are arranged at the lower part of the lifting plate, and thermal insulating layers are arranged on the inner side and the outer side of each heat-sealing frame. The positioning and leveling mechanisms are arranged in the heat-sealing frames, and connecting rods are fixedly arranged between the heat-sealing frames. Cutting mechanisms are arranged on the two sides of the heat-sealing frames. The heat-sealing overlock device has the beneficial effects that the device is convenient to position and level a mask through the positioning and leveling mechanisms, is convenient to lift up and down the height a positioning pressure block through a first hydraulic rod, so that the positioning pressure block can position the middle part of the maskunder the heat-sealing frames to avoid the mask moving during heat-sealing overlock.

Description

technical field [0001] The invention relates to the technical field of mask processing, in particular to a heat-sealing and seaming device for mask processing. Background technique [0002] A mask is a sanitary product, generally refers to a 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. It is made of gauze or paper, etc. The mask has a certain filtering effect on the air entering the lungs. When respiratory infectious diseases are prevalent, when working in a polluted environment such as dust, wearing a mask has a very good effect. In the process of mask processing, the outer edge needs to be cleaned. Seaming, so heat sealing seaming device is required. [0003] The existing heat-sealing device for mask processing does not have a corresponding mask limit structure during the process of conveying and loading materials, and the mask canno...

Problems solved by technology

[0004] The purpose of the present invention is to provide a heat-sealing and seaming device for mask processing to solve the problem that the existing heat-sealing and seaming device for mask processing proposed in the background technology does not have a corresponding mask limiting structure during the process of conveying and loading materials. And in the process of processing, the mask cannot be positioned, which will easily affect the heat sealing and seaming operation, and it is not convenient to level the mask, and it is prone to wrinkles that affect the processing quality of the mask
