Description

Sanitary waste treatment equipment {SANITARY WASTE TREATING APPARATUS}

The present invention relates to a sanitary waste disposal device, and more specifically, to a sanitary waste disposal device that can easily dispose of pet toilet pads, urine and feces, diapers, etc. for pets, children's hospitals, infants and children's facilities, or at home.

In general, in cases where pets cannot defecate outdoors, such as in apartments or townhouses, install a defecation pad with an absorbent and waterproof layer in the place where the pet defecates and dispose of the excrement along with the pad. do.

If these toilet pads are not disposed of immediately after defecation, the foul odor will spread to the surrounding area, and pets may walk around while stepping on excrement, contaminating the indoor floor. Therefore, by connecting a litter sheet to a roller, the used litter sheet can be placed on a roller. There is a proposed method of rolling it up and recovering it in the form of a roll and storing it inside the case. However, before disposing of the pad, which is temporarily stored in the form of a roll after use, as the pad decays, the odor generated becomes stronger, and the feces are separated. The storage container had to be washed separately, and especially in hot and humid environments such as summer, the odor from pet excrement gets worse, so the frequency of discarding the toilet pad roll and removing the feces from the container increases, which is inconvenient. There was this.

In addition, when separating used toilet pad rolls from the disposal device or disposing of feces from the container, toilet paper or disposable plastic gloves were used for hygiene reasons, which also caused environmental pollution.

Meanwhile, hygienically disposing of urine and feces in children's hospitals, as well as diapers for infants' urine and feces at home, are emerging as important issues for maintaining a hygienic living space for infants and children.

To solve this problem, a toilet diaper packaging device with an odor removal function neutralizes and deodorizes the odor of the toilet diaper, compresses the volume of the deodorized toilet diaper, and then compresses and packs the packaging containing the toilet diaper. It is being proposed.

However, the conventional method of processing toilet pads or toilet diapers not only requires manual work to separately package the toilet pads or toilet diapers and then seal them, but also requires the use of transfer rollers or compression rollers for the sealed toilet pads, etc. When reducing the volume after use, there was a problem that the compressed pad was damaged and easily leaked.

In addition, the conventional method of processing toilet pads or toilet diapers had a problem in that it was difficult to continuously cut and set the wrapping paper for sealing the toilet pad after one operation.

The tension bar 52, which is driven to rotate by the tension drive motor, is configured to apply tension to the packaging film by pressing the packaging film against the tension support pad when it comes into contact with the tension support pad.

When the packaging film and the sanitary waste sealed around the sanitary waste by the pressure roller 21 are detected by the first sensor unit, the tension driving motor 53 is driven to cause the tension bar to move the sanitary waste. Tension is applied to the packaging film by pressing the lower side of the packaging film surrounding the tension support pad. Then, while rotating the cutting blade, the cutting unit is moved by the cutting drive unit to cut the packaging film at the upper part of the sanitary waste while maintaining tension.

When the packaging film is cut, the tension bar is rotated to its original position to drop and accommodate the sanitary waste into the storage tank. The lower ends of the packaging film at the cut portion are adhered to each other by adhesive force, and when the user inputs another sanitary waste, the sanitary waste is sensed and the film supply roll and the pressure roller are rotated again to produce the sanitary waste. As the waste descends under its own weight, it is sealed with a packaging film.

The tension pressing unit cuts the packaging film safely and accurately while maintaining tension on the packaging film, and continuous packaging is possible for subsequent sealed packaging, enabling safe, rapid and continuous processing even if sanitary waste is processed multiple times. possible.
