Description

Structure of environment-friendly straw and manufacturing device and method thereof

Technical Field

The invention relates to a structure of an environment-friendly straw, a manufacturing device and a manufacturing method thereof, which can improve the overall manufacturing efficiency and are safe and sanitary.

Background

The straw for absorb the liquid in the container, hollow cylinder is most, mainly utilizes atmospheric pressure to reach the purpose of absorbing liquid, under atmospheric environment, inserts liquid when straw one end, and when the air or the liquid in the straw were taken away to the other end, intraductal pressure can reduce to the pressure that is less than atmospheric environment, makes the outside atmospheric pressure of straw act on the outside liquid of straw on the surface, and then in impelling the straw with liquid, makes intraductal pressure and outside of tubes pressure reach the equilibrium.

The most common suction tube in the past is made of plastic, and with the rising of environmental protection consciousness, the paper suction tube has gradually replaced the plastic suction tube. The disposable straw is a good alternative to plastic straws for mass-market drinkers and beverage stores, because paper straws are less environmentally-burdensome than plastic straws, regardless of contamination during the manufacturing process or decomposition after use.

However, the above paper drinking straw has the following problems and disadvantages to be improved:

first, it is mainly made by three-roll type mutual spiral winding, and its manufacturing speed is slow, and only about 200 paper straws can be made in one minute.

Secondly, the three rolled paper sheets are spirally wound to form a suction pipe and then fixed by the viscose, and if the three rolled paper sheets are used for sucking hot drinks, the viscose is dissolved in the drinks, thereby affecting the health of human bodies.

Thirdly, drying is carried out for 3-5 minutes after bonding, and the manufacturing efficiency is reduced.

In this embodiment, the first joining edge 111 and the second joining edge 112 are long edges of the base paper layer 1 as an example.

The sheet shape of the present embodiment is exemplified by a continuous flat state, but is not limited thereto.

Referring to fig. 1 to 9, the manufacturing method of the present invention includes the steps of:

(a) arranging at least one roll of laminating paper on at least one feeding module;

(b) operating the feeding module to make the roll of film coated paper be delivered out in a sheet-shaped winding manner;

(c) conveying the roll of laminated paper into at least one forming module, and bending and forming at least one base paper layer by the forming module so as to enable at least one first joint edge and at least one second joint edge on the base paper layer to be mutually butted; and

(d) the base paper layer formed by bending is conveyed into at least one hot pressing module, and at least one first laminating layer on the first joint edge and at least one second laminating layer on the second joint edge are hot pressed by the hot pressing module, so that the first joint edge and the second joint edge are mutually butted and combined, and the winding drum laminating paper is tubular.

It can be known from the above description that, when a user wants to manufacture an environmental-friendly straw, the roll of laminating paper 1 needs to be installed on the feeding module 2, the feeding module 2 is driven to rotate the feeding module 2, and the roll of laminating paper 1 is driven to be wound and conveyed out in a continuous flat state, at this time, if the position of the feeding module 2 is taken as the front side and the position of the hot-pressing module 4 is taken as the rear side, the first laminating layer 12 is located on the upper side of the base paper layer 11, the second laminating layer 13 is located on the lower side of the base paper layer 11, the first bonding edge 111 is located on the left side of the base paper layer 11, and the second bonding edge 112 is located on the right side of the base paper layer 11.

When the flat roll of film-coated paper 1 enters the first forming module 31 of the forming module 3, the concave roller located below in the first forming module 31 can make the original flat roll of film-coated paper 1, and the first joint edge 111 and the second joint edge 112 thereof are gradually bent upward, so that the roll of film-coated paper 1 is conveyed forward in a U-shape, and the concave and convex rollers are mutually clamped and squeezed in cooperation with the convex roller located above, so that the roll of film-coated paper 1 stably enters the second forming module 32 in a U-shape sheet shape.

After the roll laminated paper 1 enters the second forming module 32, the upper and lower semicircular concave rollers in the second forming module 32 are abutted against each other to present a circular shape, so that after the roll laminated paper 1 in a U-shaped sheet state enters, the first joint edge 111 and the second joint edge 112 of the roll laminated paper can be extruded and bent by the semicircular concave rollers above the first joint edge 111 and the second joint edge 112 due to the protruding circular shape presented by the semicircular concave rollers, and gradually approach each other until the first joint edge and the second joint edge are overlapped and butted with each other, so that the roll laminated paper 1 is changed into an O-shape from the U-shape, thereby forming a circular tube.

At this time, the first bonding edge 111 and the second bonding edge 112 are overlapped with each other, but are not bonded with each other, and at this time, the first lamination layer 12 of the first bonding edge 111 is attached to the second lamination layer 13 of the second bonding edge 112, and then the roll lamination paper 1 of the circular tube is conveyed into the hot pressing module 4, and the hot pressing module 4 performs hot pressing on the roll lamination paper 1 by using the change of temperature and pressure, at this time, the first lamination layer 12 on the first bonding edge 111 and the second lamination layer 13 on the second bonding edge 112 are mutually hot pressed and bonded through the material characteristics of the heat sealing, so that the first bonding edge 111 and the second bonding edge 112 are overlapped with each other, and the roll lamination paper 1 is stably formed into a circular tube shape, thereby forming the environmental-friendly straw of the present invention.

In addition, the roll of laminated paper 1 subjected to thermocompression bonding does not lose its adhesiveness due to the temperature of the liquid, thereby avoiding the occurrence of softening of the roll of laminated paper 1 or separation of the first bonding edge 111 and the second bonding edge 112.

The roll laminated paper 1 is formed by coating the composite material on the surface of paper by a special machine to form the first laminated film layer 12 and the second laminated film layer 13, wherein the first laminated film layer 12 and the second laminated film layer 13 formed by the composite material have the characteristics of oil resistance, water resistance and heat sealing, so that the first laminated film layer 12 and the second laminated film layer 13 subjected to hot pressing are combined with each other. The composite material may be one of Polyethylene (PE), polypropylene (PP), polylactic acid (PLA), Chlorinated Polyethylene (CPE), or polybutylene succinate (PBS), but not limited thereto.

By adopting the structure and the steps, each roll of the film-coated paper 1 can be continuously produced for 40-50 minutes, and the production efficiency of about 1000 environment-friendly straws per minute is achieved. In addition, 27000-40000 circular straws with the length of 20cm and the inner diameter of 0.6cm can be manufactured by the structure with the diameter of 150-200 cm of the roll of film-coated paper 1, so that the whole manufacturing efficiency is improved, and meanwhile, the invention can be combined into a tube shape without using adhesive through the material characteristics of the first film-coated layer 12 and the second film-coated layer 13, thereby achieving the effect of safety and sanitation.
