A Programmable Controlled Elastic Waistline Online Cutting and Transferring Mechanism

Abstract

The invention discloses a programmable control elastic waistline online cut-off transfer mechanism which comprises adsorption rotary discs. The adsorption rotary discs are arranged at one ends of transition shaft seats through middle fixed plates. The transition shaft seats are fixedly arranged on a mounting plate with a fixed hole. The other ends of the transition shaft seats are provided with first drive wheels. A drive shaft is arranged at the position deviating from the centers delta h of the transition shaft seats. A drive disc is arranged at one ends of the drive shafts. Knife anvils are distributed on the drive disc. A negative-pressure air distribution cavity for transferring cut-off materials is fixed to the outer side of the drive disc. A cutting device is arranged below the drive disc. The other end of the drive shaft is provided with corresponding second drive wheels fixed with the drive shaft. The adsorption rotary discs are connected with a track bearing. A reversing mechanical cam is arranged below the track bearing. The problem that speeds are different when elastic waistlines of products of different lengths are combined is solved. The characteristic of providing the escaping function is kept. The workload of changing accessories in the escaping work is omitted.

Description

technical field [0001] The invention relates to hygienic product machinery manufacturing equipment, in particular to a programmable-controllable elastic waist online cutting and transferring mechanism. Background technique [0002] In order to reduce the production cost of hygienic products, products with elastic waist structure made online also emerged as the times require. Due to the diversity of products produced by equipment, the existing elastic waist online production mechanism often cannot provide functional support for simple replacement of mechanical cams. It can only be a set of assemblies to adapt to multiple different products. The manufactured elastic waist mechanism can only provide one composite speed, which will cause different elastic waist flatness of products of different product sizes, which will affect product quality; it is even necessary to equip several sets of elastic waist online production mechanisms with different speeds to meet production needs, ...

Problems solved by technology

Due to the diversity of products produced by equipment, the existing elastic waist online production mechanism often cannot provide functional support for simple replacement of mechanical cams. It can only be a set of assemblies to adapt to multiple different products. The manufactured elastic waist mechanism can only provide one composite speed, which will cause different elastic waist flatness of products of different product sizes, which will affect product quality; it is even necessary to equip several sets of elastic waist online production mechanisms with different speeds to meet production needs, so that In the face of different products, it is necessary to replace the mechanical cam used to control the adsorption turntable, which increases the workload and increases the production cost of the equipment

[0003] The Chinese patent application with the application number 201410333234.8 discloses an elastic waist cutting and transferring device. The device uses a rotating method to cut the transported elastic material by using a cutting mechanism and a base on the turntable matched with it. The two adsorption devices on both sides of the base absorb the elastic material, so as to realize the stretching and adsorption of the elastic material, and then the cutting structure retracts the cutter, and the turntable rotates, so that the elastic material is transferred, and the adsorption device can be used Rotate the setting on the turntable, so that the elastic material can be turned horizontally, so that it can be directly compounded with diapers, making the whole compounding process easier, stronger in operability, and higher in work efficiency, but this technical solution can only be aimed at the same product. , can only provide one composite speed, cannot adapt to products of different lengths, and has a limited range of applications
