Description

Technical Field

[0001] The utility model relates to the technical field of sanitary napkin products, and more specifically to a glue coating device for processing expanded paper of a water-absorbing paper core. Background Art

[0002] A diaper is a commonly used daily necessity for babies, and is another name for a disposable diaper, a disposable diaper sheet or a pull-up diaper. A dry diaper can keep a baby sleeping soundly throughout the night. Because of its strong water absorption, it is commonly known as a "disposable diaper". The absorbent paper core of a diaper contains a highly water-absorbent resin (abbreviation: high molecular SAP, Superabsorbent polymer), and its water absorption and water storage capacity are astonishingly large.

[0003] During the production process of the absorbent paper core, the process of applying glue to the expanded paper is involved. At present, when the expanded paper is conveyed, fluff will be generated in the air. After a long time, the glue spraying holes at the bottom of the glue spraying box are easy to be blocked by the accumulated fluff. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a glue coating device for processing expanded paper of a water-absorbing paper core, which is provided with an upper dust suction box and a lower dust suction box above and below the expanded paper, has a good dust removal effect, and is not easy to be blocked for the glue spraying box, so as to solve the above technical problems.

[0005] The utility model specifically adopts the following technical solutions to achieve the above purpose:

[0006] A glue coating device for processing expanded paper of a water-absorbing paper core includes paper guiding rollers arranged on the left and right for conveying the expanded paper. An upper dust suction box and a lower dust suction box are respectively arranged above and below the expanded paper. A communicating pipe is arranged on the side wall of the upper dust suction box. One end of the communicating pipe is communicated with the upper dust suction box and the other end is communicated with the lower dust suction box. A dust collector is installed on the top of the upper dust suction box. The air inlet of the dust collector is communicated with the upper dust suction box. A through groove is arranged at the bottom of the upper dust suction box. A glue spraying box is installed at the bottom of the through groove. Glue spraying holes are arranged at the bottom of the glue spraying box. A glue coating roller is arranged below the glue spraying box. Support plates are fixedly connected to the front side and the rear side of the upper dust suction box respectively. The two ends of the glue coating roller are rotatably connected to the support plates.

[0007] Structural principle: The paper guiding rollers are used for conveying the expanded paper. Glue is stored in the glue spraying box. The glue comes out through the glue spraying holes and drips onto the glue coating roller. The glue is evenly coated on the expanded paper through the glue coating roller. The dust collector works to absorb the fluff generated above and below the expanded paper through the upper dust suction box and the lower dust suction box, so as to avoid the fluff blocking the glue spraying holes and affecting the liquid discharge of the glue spraying holes.

[0008] On the left and right sides of the bottom surface of the upper dust suction box and on the left and right sides of the top surface of the lower dust suction box, grooves are respectively provided. Dust suction holes are provided at the bottom of the grooves, and a dust sticking plate is installed on the grooves. The dust sticking plate is provided with air permeable holes communicated with the dust suction holes. The dust suction holes are respectively communicated with the upper dust suction box and the lower dust suction box. The dust sticking plate is arranged to adsorb the generated lint for preliminary dust removal. The lint that is not removed is cleaned by a vacuum cleaner through the air permeable holes and the dust suction holes. The lint is processed more cleanly and thoroughly through the dust sticking plate.

[0009] On the front side and the rear side of the upper dust suction box, mounting plates are respectively fixedly connected. An inclined liquid guide plate is installed between the two mounting plates. A gap is left between the bottom of the liquid guide plate and the outer wall of the glue coating roller. The setting of the gap is used to control the thickness of the glue on the outer wall of the glue coating roller so that the glue is evenly distributed on the outer wall of the glue coating roller.

[0010] The mounting plate is provided with inclined waist-shaped holes. Fixing bolts are provided on the waist-shaped holes. The fixing bolts pass through the waist-shaped holes and are bolted to the liquid guide plate. The setting of the fixing bolts is used to fix the liquid guide plate on the mounting plate. The setting of the waist-shaped holes is used to adjust the liquid guide plate and thus adjust the width of the gap between the liquid guide plate and the glue coating roller, and finally achieve the adjustment of the thickness of the glue coated by the glue coating roller.

[0011] On the top surface of the lower dust suction box, a recovery groove is provided below the glue coating roller. When the glue coating roller applies glue, the glue will overflow from the edge of the expanded paper, causing waste of glue. The setting of the recovery groove is used to recover the glue to avoid waste.

[0012] The beneficial effects of the present utility model are as follows:

[0013] In the present utility model, the glue comes out through the glue spraying holes and drips onto the glue coating roller. The glue is evenly coated on the expanded paper through the glue coating roller. When the vacuum cleaner works, the lint generated above and below the expanded paper is absorbed through the upper dust suction box and the lower dust suction box to prevent the lint from blocking the glue spraying holes and affecting the liquid discharge of the glue spraying holes; the dust sticking plate is arranged to adsorb the generated lint for preliminary dust removal. The lint that is not removed is cleaned by a vacuum cleaner through the air permeable holes and the dust suction holes. The lint is processed more cleanly and thoroughly through the dust sticking plate; the setting of the gap is used to control the thickness of the glue on the outer wall of the glue coating roller so that the glue is evenly distributed on the outer wall of the glue coating roller; the setting of the recovery groove is used to recover the glue to avoid waste.
