High-speed full-automatic irretention trouser and training trouser production line and method for producing same

Abstract

The invention relates to a high-speed full-automatic irretention trouser and a training trouser production line and a method for producing same, having the function of accurately and reliably carrying out hot-pressure welding at a high speed on the waistlines of a pair of irretention trousers and a pair of training trousers, which are formed by multiple layers of non-woven fabrics. The invention comprises an irretention trouser and training trouser production line, wherein, an upper synchronous transmission mechanism and a lower synchronous transmission mechanism in trouser waistline hot-pressure welding equipment in the irretention trouser and training trouser production line are respectively positioned oppositely on the lateral faces of a vertical stander by shafts, the upper synchronous transmission face of the upper synchronous transmission mechanism is opposite to the synchronous transmission face of the lower synchronous transmission mechanism, a plurality of dentiform pressure blocks are arranged at a certain interval and are respectively positioned on the upper synchronous transmission face and the lower synchronous transmission face, an electrical heated tube in each dentiform pressure block is connected with a power wire in a conducting ring by a telescopic electric wire and a wiring flange, the conducting ring rotates synchronously along with the upper synchronous transmission mechanism and the lower synchronous transmission mechanism, the upper and lower mobile flat guide rails are respectively positioned on the inner sides of the synchronous transmission facesof the upper synchronous transmission mechanism and the lower synchronous transmission mechanism, and the rail faces of the upper and lower mobile flat guide rails are opposite to each other.

Description

technical field [0001] The invention relates to a high-speed automatic incontinence trousers and training trousers production line and the production of incontinence trousers and training trousers capable of hot-press welding the waist circumference of the incontinence trousers and training trousers with high speed, accuracy and reliability. The method belongs to the production line manufacturing field of incontinence pants and training pants. Background technique [0002] The applicant's authorized announcement number CN1234308C, titled "Infant Training Pants Forming Composite Device and Forming Method", in this patent, the patterned mold wheel or mold roller in the welding mechanism cooperates with the ultrasonic die head, and the waist and legs of infant training pants When the upper part of the material passes through the gap formed by the pattern die wheel or the die roller and the ultrasonic die head, the ultrasonic waves emitted by the ultrasonic die head make the mol...

AI Technical Summary

Problems solved by technology

The points that need to be improved are: First, due to the small diameter of the shaft that is socketed with the pattern die wheel, the wheel surface of the pattern die wheel and the end face of the welding head of the ultrasonic welding generator are not matched with a wide face, but with a narrow face. For the gradual welding of the workpiece to be welded (attached image 3 ), it is not suitable for the instantaneous one-time welding of the welded sheet, and the reliability of the welding is not ideal; the second is that there is only one set of ultrasonic welding heads corresponding to it on the surface of the pattern die wheel, so only one-time welding can be realized. It is impossible to carry out secondary welding, tertiary welding, and multiple welding, especially for multi-layer welded objects, which cannot be effectively welded at all; third, due to welding efficiency, it directly affects incontinence pants, baby training pants, baby pull-up pants, The production efficiency of production equipment such as sanitary napkins and other sanitary products; Fourth, because the pattern die wheel has no preheating structure, the welding speed of the welded piece between the wheel surface of the pattern die wheel and the welding head of the ultrasonic welding generator is low and the welding strength is low. Low; five is in the same material, the same thickness, the same welding speed, the same power, the same frequency, the same amplitude, the same ultrasonic welding mold, the same module shape (pattern wheel or pattern block), the same pattern tooth-shaped module, the same welding gap In this case, because the background technology welds on the narrow side of the object to be welded, the welding time is short, and there is no preheating device for the welding module, so not only the welding speed is low, the welding strength is low, but also it is impossible to achieve thick or multi-layered objects Chip welding
