Unilateral fixation folding device for diapers

Abstract

The invention aims to provide a unilateral fixation folding device for diapers. The device comprises a feeding component, a first conveying belt, a second conveying belt and a discharging component, wherein the first conveying belt and the second conveying are both arranged in the feeding component and the discharging component in a penetrating manner in sequence and are both wide belts; the second conveying belt and the first conveying belt at the position of the feeding component are arranged in parallel; viewed from the feeding component to the discharging component, the second conveying belt twists clockwise; the second conveying belt at the position of the discharging component is overlapped above the first conveying belt, and the back face of the second conveying belt faces upwards; a press roll for pressing the first conveying belt is arranged between the feeding component and the discharging component; a folding rod is arranged on the side of the first conveying belt. The device has a simple structure, continuous and stable folding of products can be realized, and good neatness of the folded products is guaranteed.

Description

technical field [0001] The invention belongs to the field of diaper production equipment, in particular to a single-side fixing and folding device for diapers. Background technique [0002] In the production process of diapers, the unfolded flat diaper product needs to be folded in half, and then the two sides of the waist part of the diaper product are formed by thermocompression welding. [0003] The Chinese patent application publication number CN 103754689 A discloses a half-folding mechanism on the production line of pull-up pants and adult incontinence pants, which includes an O-shaped belt, which is guided by an O-shaped wheel. Wheel rods, and each set of transition wheel rods is composed of transition wheel rods arranged on both sides of the O-shaped wheel axis. The two transition wheel rods in each group are symmetrically arranged and an acute angle is formed between the two transition wheel rods. Along the O-shaped The included angles of multiple sets of transiti...

Problems solved by technology

However, this half-folding mechanism has the following disadvantages: (1) There are multiple sets of transition wheel bars along the conveying direction of the product, and each set of transition wheel bars contains two transition wheel bars, the amount of transition wheel bars is large, and the half-folding structure is complex; (2) Since the transition wheel bar is directly pressed on the back of the waist on both sides of the product to realize the two waist parts of the product slowly moving closer together, this requires that the distance between two adjacent sets of transition wheel bars should be smaller than the product in the conveying direction. length, so as to ensure that the two waist parts of the product are gradually approaching. Otherwise, the product will collapse again. Therefore, for small-sized diapers, more and more densely arranged transition wheel sets are required. Complicated and inconvenient to operate; (3) In order to ensure that the product does not deviate from left to right after folding in half, two transition wheel levers in each group need to be arranged symmetrically with the center line of the O-belt as the center line. The position adjustment accuracy of the transition wheel levers is required to be high and the operation is difficult If there is a deviation in the position of any one of the transition wheel rods in each group, it will cause left and right deviations in the folded product, which will affect the uniformity of the folded product.
