Laminating Machine The Shorter The Better

The solvent-free compound equipment is mainly composed of two parts: solvent-free compound machine (main engine) and mixing machine. The solvent-free compound machine mainly completes the operation of unwinding, tension control, coating, compound and winding. A special device for the mass transfer of adhesives. The following author focuses on the type of solvent-free compound machine, Laminating Machine tension control and volume transfer and other related content.

Today, the domestic use of solvent-free composite machine is basically used in a single station unwinding and winding this situation is determined by a variety of factors, mainly in the following three areas.

 (1) Because of the low initial viscosity of the solvent-free composite, Laminating Machine the tension control of the substrate is higher, so in the solvent-free compound process, the shorter the better. And the use of single-station model with a shorter material, Laminating Machine tension control accuracy is easier to guarantee, lower scrap rate and so on.

 (2) because the solvent-free adhesive has a certain opening time, and does not require dry composite high-temperature drying system (downtime easily lead to drying the substrate overheating deformation), Laminating Machine the use of single-station solvent-free composite machine can be Stop operation to achieve the replacement of the volume.

 (3) single-station solvent-free composite machine is relatively simple to manufacture, the cost is low. Moreover, single-station solvent-free compound machine compact structure, Laminating Machine small footprint, under normal circumstances can achieve one person operation. In the labor costs continue to rise in the moment, single-station solvent-free complex machine does have a small attraction.

The duplex solventless laminating machine is a solvent-free compound machine that simultaneously installs two rolls or core tubes on a unwinder (or reel) and enables non-stop replacement. Laminating Machine My company through several years of technical reserves, especially in-depth communication with a number of users, in early 2013 launched the first domestic SLFl00OAT duplex duplex solvent-free composite machine.

Compared with the single-station solvent-free composite machine, Laminating Machine duplex duplex solvent-free composite machine has the following advantages.

(1) high efficiency. Under normal circumstances, the solvent-free composite machine stable working speed of 300 ~ 600m / min, than the dry complex machine about 2 to 3 times higher. Laminating Machine But because of the need to shut down the replacement of the volume, so effective working hours greatly reduced, the actual utilization of equipment reduced. And duplex solventless laminating machine can greatly reduce the time to change the speed and downtime, Laminating Machine greatly improving the production efficiency, Laminating Machine the general output can be higher than 70%.

(2) significantly reduce the operating strength. Single-position solvent-free laminating machine requires frequent replacement of the roll and core tube. A unwinding or rewinding unit is replaced every 15 to 30 minutes on average, and the number of times of refueling for each shift is as many as ten times, which is very Personnel physical strength, but also accompanied by a certain degree of tension, Laminating Machine which is bound to affect the progress of solvent-free composite production and product quality. Dual-position solvent-free composite machine without stopping the advantages of the volume can be a good way to avoid this.

(3) to improve production stability. Laminating Machine The duplex solventless laminating machine greatly reduces the downtime, the tension control of the equipment, the consistency of the viscosity of the adhesive, Laminating Machine and so on, greatly improving the production stability.

However, there are some potential drawbacks to the duplex solventless laminating machine because of the longer demand, higher requirements for equipment tension control, Laminating Machine and a corresponding increase in reject rates, Laminating Machine which may be present for solvent-free composite products with low initial viscosity Will have a more negative impact. In addition, Laminating Machine the duplex station solvent-free composite machine is also significantly higher than the cost of single-station solvent-free composite machine.
