Description

Technical Field

[0001] The utility model relates to the technical field of sanitary napkin production, in particular to a mini sanitary napkin die pressing device with small wings. Background Art

[0002] Sanitary napkins are a type of sanitary product used by women during menstruation. The main materials are cotton, non-woven fabrics, pulp or polymers and polymer composite paper formed by composites of the above materials. The side design is mainly used to prevent side leakage. From the inside to the outside, it is divided into three layers: surface layer, absorbent core, and bottom layer. When using, first tear off the paper tape in the middle, stick the glued side to the middle of the underwear, and stick the two "ears" to the narrowest part of the crotch.

[0003] For example, a mini sanitary napkin with wings molding device with the authorization announcement number "CN219070974U" has two front wheel groups respectively engaged with two rows of conveying holes of the multi-layer material, and the two front wheel groups rotate synchronously, so that the multi-layer material is subjected to uniform driving force, so that the multi-layer material is synchronously conveyed to the molding roller, and at the same time, the two rear wheel groups pull the multi-layer material backward synchronously behind the molding roller, so that the conveying speed of the multi-layer material of the mini sanitary napkin with wings is consistent, so that when the two molding rollers mold the multi-layer material, the multi-layer material is subjected to uniform force, which eliminates wrinkles in the material, improves the flatness of the mini sanitary napkin with wings, and improves product quality. However, the mini sanitary napkin with wings molding device extrude the multi-layer materials of the mini sanitary napkin with wings through the molding roller, which easily causes the multi-layer materials of the mini sanitary napkin with wings to stick to the surface of the vulcanization molding roller after extrusion, and the operator needs to stop the machine and collect them manually, which requires the operator to consume more physical strength, thereby increasing the manual labor. At the same time, the film pressing device used for sanitary napkin production cannot adjust the corresponding molding points on the two molding rollers. When the thickness of other films needs to be processed, the operator needs to switch to other compatible machines for processing, thereby increasing the working limitations. Utility Model Content

[0029] Working principle:

[0030] When producing mini sanitary napkins with wings:

[0031] Preparation process:

[0032] First, the operator places the multi-layer material for producing the mini sanitary napkin with wings on the surface of the lower mold 4.

[0033] Bottom mold adjustment process:

[0034] First, according to the thickness of the mini sanitary napkin with wings to be produced, the height of the bottom film is adjusted, the first motor 202 is powered on, and the output shaft of the first motor 202 rotates counterclockwise to drive the threaded rod 203 to rotate, thereby driving the slider 204 to slide along the slide groove processed on the first fixed block 205, and at the same time, the protruding part of the slider 204 slides along the slide groove processed on the moving block 207, thereby driving the moving block 207 to slide along the surface of the fixed column 206, so that the protruding part of the moving block 207 slides downward along the through hole processed on the first shell 201, and the protruding part of the moving block 207 moves downward, driving the bottom mold 3 to move downward along the slide groove processed on the lower mold 4. When the bottom mold 3 moves to the height required to produce the mini pad, turn off the power of the first motor 202 to achieve the processing of mini sanitary napkins with wings of different thicknesses.

[0035] The molding process of mini sanitary napkin with wings:

[0036] After adjusting the position of the bottom mold 3, start the power supply of the hydraulic cylinder 10, and the telescopic end of the hydraulic cylinder 10 moves to drive the upper mold 11 to move downward. When the upper mold 11 enters the lower mold 4, the multi-layer materials of the mini wing sanitary napkin are pressed together by the upper mold 11 and the bottom mold 3, thereby completing the pressing operation.

[0037] The molding process of mini sanitary napkin with wings:

[0038] The power supply of the hydraulic cylinder 10 is started, and the telescopic end of the hydraulic cylinder 10 moves to drive the upper surface, and the upper mold 11 moves upward. When the movement does not move out of the lower mold, the power supply of the hydraulic cylinder 10 is turned off, and the power supply of the second motor 702 is started. The output shaft of the second motor 702 rotates to drive the worm 703 to rotate, thereby driving the worm gear 704 to rotate. The rotation of the worm gear 704 drives the cam 705 to rotate, so that the bent rod 706 slides downward along the slide groove processed on the second fixed block 707, and at the same time, the bent rod 706 slides along the slide groove processed on the second housing 701, and the cam 705 rotates 180 degrees counterclockwise. , so that the bending rod 705 drives the pressing plate 5 to move downward, and at the same time, the hair dryer 9 is started to blow the wind through the vent pipe 8 and the cavity and vent hole of the upper mold, so that the mini sanitary napkin with wings falls on the surface of the bottom mold 3, and then the power supply of the hydraulic cylinder 10 is started, and the telescopic end of the hydraulic cylinder 10 drives the upper mold 11 to move out of the lower mold 4. When the upper mold 11 moves to an appropriate position, the power supply of the hydraulic cylinder 10 is turned off, and the power supply of the first motor 202 is started. The output shaft of the first motor 202 rotates clockwise, so that the protruding part of the slider 204 is located at the end of the slide groove processed on the moving block 207, as shown in the attached Figure 5 As shown, the bottom mold 3 is reset and the mini sanitary napkin with wings is ejected from the lower mold 4, so that it is more convenient for operators to collect it, thereby saving manual labor.
