Description

Laminating mechanism of a double-sided laminating machine

technical field

The utility model relates to an improved invention of a laminating machine, in particular to a laminating mechanism of a double-sided laminating machine.

Background technique

Double-sided lamination means that the upper and lower films are respectively heated by the upper and lower heating rollers and then enter the composite area to be laminated with paper; the upper and lower films will have different shrinkage rates due to temperature differences. If the shrinkage rate is different, transverse wrinkles will occur, and the reject rate is high. In order to solve the problem of transverse wrinkles, only thick paper can be used, so the production cost is higher.

Contents of the invention

In view of the technical problems existing in the background technology, the technical problem to be solved by the utility model is to provide a laminating mechanism of a double-sided laminating machine that keeps the double-sided lamination of thin paper flat.

In order to solve the above-mentioned technical problems, the utility model is realized by adopting the following technical scheme: the laminating mechanism of this kind of double-sided laminating machine includes a frame, an upper film roll, a lower film roll and a compound film set on the frame. The composite roller is characterized in that the composite roller has two groups, namely the composite roller one and the composite roller two, and the composite roller one includes an upper heating roller for laminating the film and a pressure roller cooperating with the upper heating roller , the composite roller 2 includes a lower heating roller for lower film compounding and a pressure roller 2 matched with the lower heating roller, the upper heating roller and the lower heating roller are connected to a power source, and the upper heating roller The roller and the lower heating roller are synchronously driven.

The upper heating roller is arranged above the pressure roller one, and the pressure roller one is installed on the lifting cylinder.

The lower heating roller is arranged under the second pressure roller, and the second pressure roller is connected to the second cylinder.

The compounding positions of the compounding roll 1 and the compounding roll 2 are on the same horizontal plane.

Both pressure roller one and pressure roller two are rubber pressure rollers.

The utility model adopts two sets of composite rollers for the coating on the upper surface of the paper and the coating on the lower surface of the paper respectively, and separates the composite of the paper and the upper film and the composite of the paper and the lower film, thus avoiding the upper and lower Due to the different shrinkage of the film, the problem of transverse wrinkles of the paper occurs; the composite position of the composite roller 1 and the composite roller 2 is on the same horizontal plane, and the paper is composited on one side and enters the composite on the other side horizontally, so as to avoid the composited paper being in the conveying process. Wrinkles are generated in the middle; the pressure roller one and the pressure roller two are respectively driven by the lifting cylinder and the cylinder two, thereby adjusting the distance between the pressure roller one, the pressure roller two and the upper heating roller and the lower heating roller respectively, not only It is easy to wear paper, and the lamination pressure can be adjusted to improve the lamination quality; since the film is easy to be damaged, the rubber pressure roller has certain elasticity and softer contact, which can avoid film damage.

detailed description

With reference to accompanying drawing 2, the laminating mechanism of this kind of double-sided laminating machine comprises organic frame 8, upper film roll 1 that is arranged on the frame, lower film roll 9 and composite roll, and described composite roll has two groups, Composite roll 1 and composite roll 2 respectively. The composite roll 2 is arranged in front of the composite roll 1. The composite positions of the composite roll 1 and the composite roll 2 are at the same horizontal plane, that is, the paper enters the other side horizontally after being composited on one side. Lamination on one side avoids wrinkling of the paper after one-side lamination. Described composite roller one comprises the upper heating roller 2 that is used for upper film compounding and the pressure roller one 5 that cooperates with upper heating roller, and described upper heating roller 2 is arranged on the top of pressure roller one 5, and described pressure roller One 5 is installed on the lifting cylinder 7; the composite roller two includes a lower heating roller 6 for lower film compounding and a pressure roller two 4 cooperating with the lower heating roller, and the lower heating roller 6 is arranged on the pressure roller Below the second 4, the pressure roller two 4 is connected with the cylinder two 3, the pressure roller one 5 and the pressure roller two 4 are rubber pressure rollers, the upper heating roller 2 and the lower heating roller 6 are connected with the power source connected, and the upper heating roller 2 and the lower heating roller 6 are synchronously driven, the power source is a motor, and the upper heating roller 2 and the lower heating roller 6 are synchronously driven through a synchronous belt.

When the machine is threading the paper, the lifting cylinder 7 drives the pressure roller 1 to move downward, so that there is a certain distance between the pressure roller 5 and the upper heating roller 2, and the cylinder 2 3 drives the pressure roller 2 to move upward. Make the pressure roller 2 4 and the lower heating roller 6 have a certain distance, so that the paper can be threaded; after the paper threading is completed, the lifting cylinder 7 drives the pressure roller 1 to move up to press the paper and film, and the cylinder 2 3 drives the pressure roller 2.4 moves down, presses the paper and film, the motor starts, the upper heating roller 2 and the lower heating roller 6 rotate synchronously, the upper film roll 1 and the lower film roll 9 unwind, and the lower film and paper pass through the lower heating roller 6 Heating and compounding with pressure roller 2 4 to realize one-sided lamination of paper, the paper after one-sided lamination and the upper film enter the compound roller 1 to compound the upper film of the paper, thus completing double-sided lamination; due to the lower film and the thin film The paper is compounded first, and then compounded with the upper film, which overcomes the paper wrinkle problem caused by different shrinkage rates of the film, greatly reduces the waste rate, and improves the quality of the film.
