Description

A cleaning equipment that removes glues for producing sanitary towel

Technical Field

The invention relates to the field of glue removing equipment, in particular to glue removing and cleaning equipment for producing sanitary towels.

Background

Sanitary towel is the material that an utensil absorptive power, and main material is cotton, non-woven fabrics, paper pulp or the polymer and the compound paper of polymer that above material compound formed, and the design of side mainly is used for preventing the edge leakage, because can present certain angle with the sanitary towel body during the use, more easily with the part of the groin friction, consequently the side sanitary towel that uses soft material is more favored by women. The sanitary towel is divided into three layers, namely a surface layer, an absorption core and a bottom layer. The back adhesive of the sanitary napkin is a waterproof material, and can retain menstrual blood in the sanitary napkin to absorb the menstrual blood flowing out from the vagina when women have menstrual flow. Use the conveyer belt to carry out directional conveying to the sanitary towel in the production process in the production water line of sanitary towel, wherein, in the packaging process of sanitary towel, need carry out the bonding packing to sanitary towel with the colloid, often have remaining colloid on the conveyer belt after the packing, among the prior art, need the staff to carry out manual striking off, very inconvenient, be difficult to scrape totally moreover.

In order to improve the scraping effect, the invention patent with the patent number of 201810540341.6 discloses a degumming cleaning device for producing sanitary towels, which comprises a conveying table, auxiliary supports, a transmission roller, a driving motor, a conveying belt, a U-shaped frame, a tool storage hopper, a handle, supporting legs, a fixed transverse plate, a belt surface circulating humidifying frame structure, a buffering and material guiding belt surface degumming frame structure, a viscose debris collecting and storing frame structure, a secondary degumming grinding frame structure, a belt surface dust debris scraping frame structure and auxiliary guide rollers, wherein the auxiliary supports are longitudinally welded at four corners of the middle lower part of the conveying table respectively; the transmission roller shafts are connected to the left side and the right side of the conveying table. The arrangement of the water guide pipe, the miniature self-priming pump, the sponge guide roller and the water pumping pipe is beneficial to conveniently pumping water liquid in the water storage tank to play a primary humidifying role on the conveying belt, so that the effect of scraping the viscose glue on the conveying belt by the glue scraping blade can be promoted; the rubber scraping strip and the liquid guide frame are arranged, so that the scraping effect on redundant liquid on the conveying belt is facilitated, and the redundant liquid is prevented from being splashed outwards.

However, the above devices have the disadvantages that: 1. although the device can primarily humidify the adhesive colloid on the conveying belt, the colloid is in a solidified hard state in the colloid, and the colloid is scraped hard with the scraper blade through the scraper blade, so that the blade can be damaged, and the conveying belt has certain ductility, so that the colloid can be separated from the scraper by vibration generated by the conveying belt when the scraper contacts with the conveying belt, and incomplete scraping is caused; 2. the sponge guide roller is contacted with the upper end opening of the water conduit, so that splash can be caused when water is sprayed to the sponge guide roller, and the environment is polluted.
