Description

Technical Field

[0001] This utility model relates to a sealing device, specifically a sealing device for the absorbent core of a diaper, and belongs to the field of diaper processing technology. Background Technology

[0002] Disposable diapers are a common daily necessity for babies, encompassing various types such as diaper pads, pull-ups, and disposable diapers. Dry diapers allow babies to sleep soundly through the night; due to their high absorbency, they are commonly known as "disposable diapers." Highly absorbent polymer (HIP) is an excellent material for manufacturing baby diapers; it is made primarily from starch and acrylates and requires a sealing process during diaper production.

[0003] Chinese patent application publication number CN221672324U discloses a sealing device for diaper production. This utility model keeps the position of the diaper and the sealing device at the same level, making sealing more convenient and preventing the sealing edge from shifting. Through the pressure plate and the elastic connecting component, the diaper can be pressed down to prevent the diaper from becoming fluffy and the packaging bag from sticking up, which would cause the sealing edge to be tilted or difficult to seal.

[0004] While the above-mentioned patent solution can fix the diaper and prevent the packaging bag from sticking up, the sealing device in the above-mentioned patent is not convenient to unfold the diaper when pressing it. Since the diaper itself has a certain elasticity, it is easy for the diaper to curl up when placed on the processing board, which makes the diaper prone to wrinkles when pressed, thus affecting the sealing effect of the diaper.

[0005] Therefore, a sealing device for the absorbent core of a diaper is proposed here. Utility Model Content

[0035] In use, the following steps are taken: The diaper is placed on the surface of the working plate 1. The first motor 51 is started, driving the first threaded rod 52 to rotate. Through the cooperation between the first threaded rod 52 and the transmission sleeve 53, the moving rod 54 slides inside the slide groove 31, causing the first support rod 55 to rotate. Simultaneously, the slider 57 slides inside the limiting groove 41. The cooperation between the first support rod 55 and the second support rod 56 causes the lifting plate 4 to move downwards. Through the support block 61 and the connecting plate 62, the first arc-shaped pressure plate 63 contacts the surface of the diaper. The lifting plate 4 continues to move downwards, using the two first arc-shaped pressure plates 63 to push the diaper outwards around the support block 61, thus unfolding the diaper and preventing folding during pressing. Then, the second motor 81 is started, driving the second threaded rod 82 to rotate. Through the second threaded rod 82 and the transmission block 83, the sealing frame 7 slides on one side of the working plate 1, enabling the sealing frame 7 to perform a moving sealing operation.
