Description

Liquid feeding equipment and liquid feeding mode for wet towel production

Technical Field

The invention relates to the technical field of wet towel production, in particular to liquid adding equipment and a liquid adding mode for wet towel production.

Background

Wet tissues, also called wet tissues or wet tissues, are tissues which are soaked in cleaning liquid in advance and are used for cleaning skin, surfaces or articles; it contains moist ingredients, which can help remove dirt, bacteria and other impurities, and make the skin feel fresh and comfortable. The process of conventional wet wipe production can be broadly divided into: preparing materials, folding, adding liquid, cutting, stacking, packaging, sealing, inspecting quality and warehousing finished products; the liquid adding step plays a critical role, and directly influences the cleaning effect, nursing effect and product stability of the final wet tissue product. Various liquid adding devices for wet towel production are proposed by manufacturers, and the following problems exist in the practical application process:

1. Such as: patent application number 202321586444.9, entitled liquid injection mechanism for wet wipes. The device extrudes saturated wet tissues by utilizing the lower pressing plate and the top plate, collects extruded disinfectant, reduces production cost and effectively avoids the waste of the disinfectant. The method can adopt a mode of adding liquid first and then cutting and stacking, so that the situation that liquid in wet tissues is polluted in the cutting process is easy to occur, and the situation that the cut wet tissues are dried at edges and uneven in liquid distribution can be caused; even to avoid contamination of the cutting device by liquids on wet wipes, the difficulty and cost of cleaning and maintenance of the cutting device is increased.

2. Such as: patent application number 202310891858.0, entitled processing equipment for producing moisturizing paper towels and method thereof. The device sprays the inside of the tissue from the upper direction and the lower direction through the first spray assembly by setting the opening of the tissue to be in an up-down direction; the spraying mode can accelerate the downstream speed of the moisturizing liquid and improve the liquid adding efficiency of the wet tissues. However, this approach still relies on the downward flow characteristics of the liquid to increase the liquid filling efficiency, which is limited to some extent; at the same time, it is difficult to distribute the liquid more quickly and evenly on the towel. The device adopts a mode of stacking first and then adding liquid and cutting, and has the same problem as a liquid injection mechanism for wet tissues in the patent.

Furthermore, since the towels have been subjected to the filling process during the stacking process, the inner wet components of the towels are relatively high, whereas the edge portions of the towels are relatively low. When slitting is carried out, the situation that a large amount of liquid in the wet tissue is lost easily is caused, and the situations of edge drying and uneven liquid distribution are aggravated. The process of stacking and then cutting firstly increases the cutting difficulty of the wet tissues after liquid adding, and aggravates the situations of uneven drying and liquid distribution at the edges of the wet tissues.

3. Such as: the application number is 202311481711.0, and the name is a full-automatic wet tissue liquid adding device. The equipment fixes and turns over the stacked wet tissues through the turning mechanism to carry out high-precision spraying and liquid adding; solves the problems that the liquid adding amount is difficult to accurately control and each part of the stacked wet tissues is difficult to fully and uniformly permeate. The liquid adding uniformity of the stacked wet tissues is realized through overturning, and the stacked wet tissues can be stacked to form a certain fluffiness; if the stacked wet tissues are not compacted and fixed, loose scattering of the stacked wet tissues can occur in the overturning process; if the stacked wet tissues are compacted and fixed, the condition that liquid is difficult to uniformly permeate the wet tissues can occur in the spraying process.

In summary, it is found that the prior art has at least the following technical problems:

the existing liquid adding equipment for producing wet tissues adopts liquid adding firstly and then cutting, which is easy to cause the conditions of drying and uneven liquid distribution at the edges of the wet tissues; and stacking the wet tissues in a stack makes it difficult to more quickly and uniformly distribute the liquid over the tissues.
