Description
Technical Field
[0001] The utility model relates to the technical field of disposable absorbent articles, in particular to a composite core feeding device. Background Art
[0002] Disposable absorbent products such as diapers and sanitary napkins mainly absorb liquids through composite cores. Currently, composite cores are mainly directly conveyed by conveyor belts, laminated with the surface layer, and then laminated with the bottom layer, so that the composite core is wrapped between the surface layer and the bottom layer.
[0003] Whether it is diapers or sanitary napkins, the main problem is the side leakage problem. After slitting, the composite core enters the conveyor belt. If the entry end is not parallel, it will deflect to one side due to the differential speed of the conveyor belt and itself. In order to increase the spacing between the composite cores, the conveyor belt will increase the conveying speed by coating the surface layer and the bottom layer at intervals. Under the accelerated conveying of the conveyor belt, the composite core is prone to further deflection. Not only will it tilt itself, but it will also deviate from the center of the conveyor belt, causing the core of the manufactured diapers and sanitary napkin products to deflect to one side, exacerbating the side leakage problem.
[0004] In order to solve the above problems, this case proposes a feeding device that can correct the overlapping position of the composite core. Utility Model Content
[0005] Therefore, in view of the above problems, the utility model proposes a composite core feeding device with reasonable structural design and capable of correcting the covering position of the composite core.

[0007] A further improvement is that a spacing adjustment structure is provided between the two mounting plates for increasing the stability of the mounting plates and adjusting the spacing between the mounting plates to accommodate the installation of pulleys of different lengths and belts of different widths.
[0008] A further improvement is that the distance adjustment structure includes at least one group of a first threaded rod, a second threaded rod, and a threaded sleeve, the first threaded rod and the second threaded rod are respectively fixed horizontally on the inner side surfaces of the two mounting plates, the threads of the first threaded rod and the second threaded rod are opposite, and the two ends of the threaded sleeve are respectively threadedly connected and sleeved on the first threaded rod and the second threaded rod.
[0009] A further improvement is that: mounting lugs are respectively arranged at two ends of the outer side of the mounting plate, and the mounting lugs at the two ends can be rotatably sleeved on the rotating shafts of the first pulley and the second pulley respectively.
[0010] Further improvements are: sliding grooves are respectively provided on the mounting plate on both sides of the correction plate along the direction perpendicular to the belt conveying, a mounting screw is vertically arranged on the lower surface of the correction plate, the mounting screw is passed through the sliding groove, and nuts for locking the mounting screw are respectively arranged on the upper and lower surfaces of the mounting plate, and the outer diameter of the inscribed circle of the nut is larger than the width of the sliding groove.
[0011] A further improvement is that at least one rotating groove is horizontally opened on the feed side of the correction plate, and a rotating protrusion rotatably plugged into the rotating groove is arranged on the discharge side of the guide plate. Damping channels are vertically opened on the correction plate and the guide plate respectively through the middle of the rotating groove and the middle of the rotating protrusion, and a damping rod for limiting the autonomous rotation of the guide plate is interference fit through the damping channel.
[0012] By adopting the above technical solution, the beneficial effects of the utility model are:
[0013] 1. The belt width set in this case is smaller than the composite core width, so that when the belt conveys the composite core, the two sides of the composite core exceed the two sides of the belt. If the composite core is deflected, under the guidance of the guide plate, the composite core enters the correction channel between the correction plates and is centered and overlapped between the surface layer and the bottom layer under the action of the correction channel, avoiding side leakage caused by the deflection of the composite core and improving the quality of diapers and sanitary napkins.
[0014] 2.

[0016] 4. The correction plate and guide plate in this case can adjust the installation position through the sliding cooperation of the slide groove and the installation screw, so that the feeding device can adapt to composite cores of different widths without changing the accessories.
[0017] 5. In this case, the guide plate and the correction plate are directly connected by damping rotation. The angle between the guide plate and the belt can be adjusted by manual rotation, that is, the distance between the feed sides of the guide plates on both sides can be adjusted. The adjustment method is simple and effective. BRIEF DESCRIPTION OF THE DRAWINGS
