Method for glue amount on-line detecting of glue

A technology of glue and glue amount, which is applied in the direction of surface coating liquid device, coating, etc., can solve the problem of not being able to directly obtain the thickness of the glue on the composite film, the weight of the glue on the composite film, and the production of the composite film does not meet the requirements. Composite film mixed with bubbles and other problems, to avoid inaccurate glue dosage, reduce glue dosage, and achieve high accuracy

Problems solved by technology

[0002] In the existing composite film production process, since it is impossible to directly obtain the gluing thickness of the glue on the composite film or the grammage of the glue on the composite film
Therefore, there will often be too much glue or too little glue, which will lead to the production of composite films that do not meet the requirements and become substandard products.
When the amount of glue is too much, it will not only cause waste of glue, but also increase the production cost of the enterprise
When the amount of gluing is too little or insufficient, air bubbles will be mixed in the produced composite film, resulting in failure of the composite film

Embodiment 1

[0019] A kind of method of on-line detection glue glue amount of the present invention, concrete steps are as follows:

[0020] (1) Place the glue barrel of the compound machine used for gluing and compounding the film material on the electronic scale, inject glue into the glue barrel of the compound machine, record the effective solid content of the glue according to the manufacturer's information of the glue, and use a meter ruler Or use a tape measure to measure the width of the film material to be glued and compounded, and record the width Wm;

[0021] (2) Start the compound machine, adjust the speed of the compound machine, record the vehicle speed Vm / min when the compound machine works normally, and record the current weighing value M1g of the above-mentioned electronic scale;

[0022] (3) Timing with a stopwatch, record the timing time t minutes, and record the current weighing value M2g of the above-mentioned electronic scale;

[0023] (4) Substituting the data obtain...

Embodiment 2

[0036] Another preferred measurement method of a method for on-line detection of the amount of glue on the glue,

[0037] Specific steps are as follows:

[0038] (1) Select the release paper, use a knife to cut two pieces of release paper of the same size straight, and the two pieces of release paper of the same size are release paper A and release paper B;

[0039] (2) On the compound machine, paste the release paper A in step 1 on the surface to be glued on the surface layer film material to be glued; at the same time, paste the release paper B on the bottom film to be glued The surface to be compounded of the material; make the bottom layer film material pasted with release paper B close to the surface layer film material pasted with release paper A for composite pressing;

[0040](3) After waiting for the hot pressing of the compound machine, the release paper A and the release paper B are respectively located between the surface film material and the bottom film material...

Abstract

The invention discloses a method for glue amount on-line detecting of glue. The method comprises the following steps that a glue drum of a compound machine is placed on an electronic scale, and the glue is injected into the glue drum of the compound machine, and according to the manufacturer information of the glue, the effective solid content of the glue is recorded; the breadth of film materials to be glued and compounded is measured, and the breadth Wm is recorded, the compound machine is started, the vehicle speed of the compound machine is adjusted, the vehicle speed Vm / min of the compound machine during normal working is recorded, and the current weighing numerical value M1g of the electronic scale is recorded; and timekeeping is conducted by using a second chronograph, timekeeping time t minute is recorded, the current weighing numerical value M2g of the electronic scale is recorded, the above obtained data are correspondingly put into equations of M2-M1, L=V*t, S=L*W and (the glue using amount M / the gluing total area S)*the effective solid content of the glue, and the glue amount of the film materials at a unit area is calculated and obtained. By means of the method of glue amount on-line detecting of the glue, the glue amount can be more precisely detected, the glue using amount can be reduced, and the problem that the glue is too much or too less is prevented.

Description

technical field [0001] The invention relates to the technical field of gluing on packaging film materials, in particular to a method for online detection of glue gluing amount. Background technique [0002] In the production process of the existing composite film, it is impossible to directly obtain the gluing thickness of the glue on the composite film or the grammage of the glue on the composite film. Therefore, there will often be too much glue or too little glue, which will lead to the production of composite films that do not meet the requirements and become substandard products. When the amount of glue applied is too much, it will not only cause waste of glue, but also increase the production cost of the enterprise. When the amount of gluing is too little or insufficient, air bubbles will be mixed in the produced composite film, resulting in failure of the composite film. [0003] For this reason, how to more accurately and simply calculate the amount of glue applied...
