Description

Technical Field

[0001] The utility model relates to the field of folding devices, in particular to a wet wipes folding device. Background Art

[0002] With the acceleration of the pace of modern life, folding wet wipes are widely used in many scenes of public life. In the production process of folded paper towels, the non-woven fabric is usually cut into several non-woven fabric strips, and then the non-woven fabric strips are folded into two, three or four folds as needed. The utility model patent with authorization number CN219525805U provides a folding mechanism for wet wipes folding spray equipment: "including a frame, a first fixed plate is provided at both ends of the pressing roller, a cylinder is provided on the first fixed plate, a plurality of groups of folding devices are provided below the pressing device, a guide roller is provided on one side below the folding device, and a cloth passes through the folding device". The mechanism first folds vertically, and then guides the material forward horizontally through the guide roller. When the cloth passes through the folding plate, due to uneven tension distribution, it is easy to cause excessive deformation of the cloth, affecting the folding quality of the cloth. In addition, its structure is relatively complex, and the debugging is relatively cumbersome, which affects the folding efficiency of the cloth. Therefore, it is necessary to develop a wet wipes folding device to make the folding tension of the wet wipes evenly distributed, avoid excessive deformation of the cloth, and further simplify the folding device to improve the folding quality and efficiency of the wet wipes.

[0004] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a wet wipes folding device, comprising a frame, a guide assembly, a transition assembly, and a folding and forming assembly, wherein a plurality of the guide assemblies are staggered in sequence from back to front on the outside of the frame, the transition assembly is arranged between the guide assembly and the folding and forming assembly, the folding and forming assembly is arranged below the rear end of the transition assembly, the guide assemblies, the transition assemblies, and the folding and forming assemblies match the number of the guide assemblies and are fixedly connected to the frame.

[0005] The guide assembly includes a first slide rail, a first slider, a first fixed support, a first transition axis, a second slide rail, a second slider, and an optical axis. The first slide rail is transversely fixedly installed on one side of the frame. The first slider is slidably connected to the first slide rail. The left end of the first fixed support is fixedly connected to the first slider. The rear end of the first transition axis is fixedly connected to the first fixed support and is parallel to the first slide rail. The second slide rail is fixedly connected to the first fixed support and is perpendicular to the first slide rail. The second slider is slidably connected to the second slide rail. The rear end of the optical axis is fixedly connected to the second slider, and the front end is obliquely outward. By setting the guide assembly, the cloth passes upward from the inside of the first transition axis from top to bottom, passes downward above the optical axis, and then passes to the transition assembly, thereby realizing the conversion of the cloth from vertical downward to longitudinal passage.

[0006] The transition assembly includes a second transition shaft and a third transition shaft. The second transition shaft is horizontally fixedly mounted on the frame and is directly in front of the optical axis. A pair of third transition shafts are installed on the frame at intervals, are parallel to the second transition shaft, and are below the rear end of the first slide rail.

[0007] The folding and forming assembly comprises a second support, a slide rail, a slider, a screw, a fixed block, a first hand wheel, a pre-folding plate, a fixed bracket, an outer folding plate, an inner folding plate, and a second hand wheel. The second support is horizontally fixedly mounted on the frame and is below a pair of third transition shafts. The front end of the slide rail is fixedly connected to the second support and is provided with a horizontal sliding hole. The slider is slidably connected to the slide rail. The screw movably passes through the fixed block through the sliding hole, and its front end is screwed to the slider. The fixed block is fixedly connected to the rear end of the slide rail.

The upper section of the pre-folding plate is obliquely downward to the left, and the lower section is obliquely downward to the right and is fixedly connected to the fixed block, which is used to pre-fold the cloth into three folds along the walking direction. The fixed bracket is fixedly mounted on the fixed block, and at the rear side of the pre-folding plate, the outer folding plate is fixedly connected to the fixed bracket. The folding plate is parallel to the upper surface of the pre-folding plate, and is used to fold the pre-folded cloth clockwise forward. The vertical section of the inner folding plate is fixedly connected to the right side of the pre-folding plate, and the horizontal section is provided with an open inclined surface facing backwards, and is consistent with the cloth running direction to the right. The second hand wheel is screwed with the slider through the slide rail, and is used for positioning after the horizontal position of the slider is adjusted. By setting a folding forming component, when the cloth enters the upper end of the pre-folding plate through a pair of second transition shafts, the cloth is pre-folded into outer, middle and inner folds. Then, under the action of the outer folding plate, the outer folded cloth is folded forward along the pre-folding line clockwise and made to fit with the middle cloth. Then, the cloth with the outer folded is moved upward from the lower end of the vertical section of the inner folding plate and from the surface of its horizontal section to the right, and under the action of the open inclined surface of the horizontal section of the inner folding plate, the inner cloth is folded downward clockwise, and finally the cloth is folded into three folds along the running direction.
