Ear loop slitting and fixing integrated device of masks

Abstract

The invention belongs to the technical field of mask production equipment, and discloses an ear loop slitting and fixing integrated device of masks. The device has the advantage of simple structure and comprises a cutting assembly, a positioning assembly and a welding assembly, wherein the cutting assembly comprises a rotatable knife roll, N cutting knives are arranged on the knife roll in an array mode and used for cutting to obtain equal-width ear loops when the knife roll continuously rotates, the positioning assembly is located on one side of the cutting assembly and comprises a rotatable positioning roller, the positioning roller and a knife roller cooperates with each other, the positioning roller and the knife roller rotate oppositely so that the ear loops can enter the position between the cutting assembly and the positioning assembly from the position above the positioning roller, the positioning assembly further comprises a negative pressure generating mechanism, the negative pressure generating mechanism is used for driving the surface of the positioning roller to form a negative pressure state so as to adsorb and position the cut ear loops, and the welding assembly is located under the positioning assembly, comprises an ultrasonic welding head and is used for achieving ultrasonic welding of the ear loops and mask main bodies between the positioning roller and an ultrasonic welding head.

Description

technical field [0001] The invention belongs to the technical field of mask production equipment, and in particular relates to an integrated device for cutting and fixing ear loops of a mask. Background technique [0002] At present, in the process of producing disposable flat masks, the fixing of ear loops is an indispensable production link; while the existing ear loop fixing is generally completed through secondary processing, which greatly affects the production efficiency of masks . [0003] In view of the above problems, in the Chinese utility model patent CN212312835U, an automatic feeding, cutting and pressure point mechanism for the ear straps of a mask machine is proposed. Based on the setting of this mechanism, the existing mask production process is improved, so as to achieve full automation Mask production; however, in this mechanism, in order to realize the fixation of the ear straps, there are components such as the glue dispenser, the wind bucket assembly 1,...

[0002] At present, in the process of producing disposable flat masks, the fixing of ear loops is an indispensable production link; while the existing ear loop fixing is generally completed through secondary processing, which greatly affects the production efficiency of masks

[0003] In response to the above problems, in the Chinese utility model patent CN212312835U, a mechanism for automatic feeding, cutting, and pressure point of ear straps of a mask machine is proposed. Based on the setting of this mechanism, the existing mask production process is improved, so as to achieve full automation. Mask production; however, in this mechanism, in order to realize the fixation of the ear straps, there are components such as the glue dispenser, the wind bucket assembly 1, the ear strap cutting mechanism, the wind bucket assembly 2, and the ear strap pressure point mechanism, so there is an overall more complex issues
