Problems solved by technology

In these cutting transfer devices, each station needs the high coordination between the adsorption turntable and the cutting knife group. The components of the equipment require high machining accuracy, and the service life is short. The maintenance cost in daily production is also high, which is not conducive to production cost. The control also affects the improvement of its production efficiency

Embodiment 1

[0036] In this embodiment, a rail-type replaceable cam elastic waist online pull-off transfer device, such as figure 1 or figure 2 As shown, it includes a main drive disc 1, an adsorption turntable unit 2, a speed change cam 3 and a reversing cam 4. The speed change cam is arranged on one side of the main drive disc, and the reversing cam is arranged on the other side of the main drive disc. There are multiple adsorption turntable units distributed on the periphery; such as Figure 4 As shown, the speed change cam is provided with a speed change track groove 5, and the speed change track groove is a bidirectional convex curve; as Figure 5-7 As shown, there is a reversing track groove 6 on the reversing cam; image 3 As shown, the main drive disc is provided with a plurality of swing rod assemblies 7, and one end of each swing rod assembly is correspondingly connected with an adsorption turntable unit, and the other end of each swing rod assembly is embedded in the speed ch...

Embodiment 2

[0045] In this embodiment, the device described in Embodiment 1 realizes a method for online pulling and transferring of elastic waist circumference. After the unit absorbs the elastic non-woven fabric, it turns around the center of the main drive disc to generate accelerated rotation, and quickly distances itself from the position where the adsorption turntable unit absorbs the elastic non-woven fabric, thereby causing a pulling effect on the elastic non-woven fabric; as the adsorption turntable unit rotates The main drive disk continues to rotate, and the adsorption turntable unit is gradually rotated by 90° by using the change of the reversing track groove of the reversing cam, and then compounded with the composite drum outside the elastic waistline pull-off transfer device, and the elastic non-woven belt is passed through the composite drum. out.

[0046] The above-mentioned elastic waist line breaking transfer method specifically includes the following steps:

Abstract

The invention discloses an elastic waist online breaking transfer device and method. The device comprises a main drive plate, adsorption turn plate units, a shift cam and a reversing cam, wherein the shift cam and the reversing cam are arranged on the two sides of the main drive plate respectively, and the adsorption turn plate units are distributed on the periphery of the main drive plate; a two-way curve convex shift track groove is formed in the shift cam; a reversing track groove is formed in the reversing cam; the main drive plate is connected with the adsorption turn plate units and the shift track groove through an oscillating bar assembly; the bottom of each adsorption turn plate unit is connected with the reversing track groove through a reversing guide wheel. The method comprises the steps that breaking joints are pre-processed on elastic nonwoven, according to variation of the shift track groove of the shift cam, the adsorption turn plate units are made to generate breaking action on the elastic cloth when the adsorption turn plate units rotate; according to variation of the reversing track groove of the reversing cam, the adsorption turn plate units are made to gradually revolve on the axis of the adsorption turn plate units by 90 degrees and to be combined with a compound drum. The device is simple in structure, can be adapted to high-speed running of a diaper processing machine, and is low in cost.

Description

technical field [0001] The invention relates to the field of hygienic product manufacturing equipment, in particular to a device and method for online snap-off and transfer of an elastic waistline with a ring-rail type replaceable cam. Background technique [0002] The processing of elastic waist structure is an indispensable link in the production of diapers. With the continuous exploration of product manufacturers to reduce product costs, the equipment for online production of elastic waist structure has also emerged as the times require. Due to the diversity of products, the existing online production equipment for elastic waistlines often cannot provide support for simple code changes, and can only be a set of assemblies to adapt to multiple different products. The equipment can only provide a suitable speed, which will cause different elastic waistlines of different product sizes, which will affect the product quality; it is even necessary to equip several sets of elast...
