Local indentator for fiber towel, and manufacturing method of indentation in specific position of the fiber towel

Abstract

The invention relates to a local indentator for a fiber towel. The local indentator comprises a heating plate, a pattern plate disposed below the heating plate and tightly adhered to the heating plate, a fixed plate disposed below the heating plate and used for disposing the fiber towel, a supercharging device disposed above the heating plate and used for driving the heating plate to drop, and a temperature controller. An electrical heating element and a temperature sensor are disposed in the heating plate. The electrical heating element is electrically connected to the temperature controller. The temperature sensor and the temperature controller are electrically connected. The invention also provides a manufacturing method of indentation in a specific position of the fiber towel by utilization of the local indentator. According to the manufacturing method, the local indentation can be formed selectively in the specific position of the single fiber towel and pictorial trademarks, telephones, and the like can be printed on the fiber towel. The local indentator and the manufacturing method overcome limitation that the indentation of the fiber towel at present must be whole-area indentation. The local indentation can be formed selectively in the specific position of a single finished-product fiber towel. The local indentator and the manufacturing method are mainly used for indentation on catering moist wipes.

Description

technical field [0001] The invention relates to a local indentation machine for fiber towels and a method for making indentations at specific positions of fiber towels. Background technique [0002] The existing indented fiber towels in the market are all manufactured by full-area indentation process, and the local indentation manufacturing process is still blank at a specific position of a single strip, and the required trademark patterns, telephones, etc. cannot be printed on the designated positions of the produced fiber towels. In particular, the indentation production of catering wet wipes has the characteristics of small production batches, many pattern patterns, and frequent pattern changes. The existing indentation methods and equipment in the market are difficult to meet its requirements.

Problems solved by technology

[0002] The existing indented fiber towels in the market are all manufactured by full-area indentation process. The local indentation manufacturing process in a single specific position is still blank, and the required trademark patterns, telephone numbers, etc. cannot be printed on the designated positions of the produced fiber towels.

In particular, the indentation production of catering wipes has the characteristics of small production batches, many pattern patterns, and frequent pattern changes. The existing indentation methods and equipment in the market are difficult to meet its requirements.

[0003] The existing fiber towel creasing machines in the market are all large-scale roller creasing machines. The principle is to make creasing by rotating the heated rollers. The disadvantages are that the machine is bulky, the cost of equipment and the cost of plate making are high, and it can only be used for The fiber towel cloth with a width of about 2 meters and a length of several tens of meters or hundreds of meters is indented as a whole. The size of the fiber towel, the fiber towel made in this way has flower marks everywhere including the edge of the towel, and the flower marks can only be ordered according to the pattern of the plate-making design. If you need to change the flower marks on the towel, or add For different phone numbers, trademarks, etc., it is necessary to re-roll the plate. For the fiber towel imprint of the catering industry that often needs to change the format, the towel manufacturer will not be able to realize the production because the cost is too high, and the roll creasing machine cannot Print the pattern on the designated position of the fiber towel

[0004] In addition, there is also a high-frequency electromagnetic wave creasing technology for leather creasing on the market. The disadvantages are that the machine structure is complex, the purchase cost and maintenance cost are high, and the matching plate-making materials must use copper or aluminum. materials, and must be made with high-cost engraving plate-making process, which requires a high plate fee. At the same time, due to the electromagnetic technology, the single-piece printing takes a long time and increases the labor cost.

[0005] Therefore, the prior art lacks an indentation machine and an indentation method that can partially indent a single fiber towel at a specific position, so that the required trademark pattern, telephone, etc. can be printed on the designated position of the fiber towel that has been produced.
