AI Technical Summary
The existing dry composite machines can only be used as composite machines and cannot double as coating machines, resulting in low utilization and high cost of equipment.
The S-roll double-pressure multi-function pressing traction structure is adopted, including a temperature-controlled S-roll, an upper pressure roller and a lower pressure roller. The up and down movement is driven by the cylinder, and the composite and coating functions are achieved by combining the hot and cold press rollers.
The dry composite machine can be used as both a composite machine and a coating machine, which improves the versatility of the equipment and saves costs.

Abstract
Description
Technical Field
[0001] The utility model relates to a pressing and traction structure, in particular to an S-roller double-pressing multifunctional pressing and traction structure, belonging to the technical field of dry laminators. Background Art
[0002] Dry laminators and solventless laminators are devices that use solventless adhesives to laminate two or more substrates together. The lamination unit is the core part of the solventless dry laminator. Through the action of heating rollers and pressure rollers, the substrate coated with adhesive and another substrate are heated and pressed, so that the adhesive is cured under a certain temperature and pressure to complete the lamination process. Such dry laminators cannot be used as coating machines because there is only one pressure roller. Content of the Utility Model
[0003] To solve the above-mentioned deficiencies, the utility model provides an S-roller double-pressing multifunctional pressing and traction structure on the basis of a dry laminator, which can be used both as a laminator and as a coating machine.
[0004] To achieve the above purpose, the technical solution adopted by the utility model is: an S-roller double-pressing multifunctional pressing and traction structure, including a temperature-controlled S-roller, an upper pressure roller and a lower pressure roller. The upper pressure roller is located above the temperature-controlled S-roller, and the lower pressure roller is located below the temperature-controlled S-roller.
[0005] Preferably, the temperature-controlled S-roller includes a cold pressing roller and a hot or cold pressing roller. The cold pressing roller is located below the upper pressure roller, and the hot or cold pressing roller is located above the lower pressure roller.
[0006] Preferably, the upper pressure roller and the lower pressure roller are driven to move up and down by air cylinders.
[0007] Preferably, there is a liquid medium in the temperature-controlled S-roller.
[0008] The utility model improves the lamination unit of the traditional dry laminator and solventless laminator, achieving the effect of multi-purpose use. It can be used both as a dry laminator and as a coating machine, greatly saving costs. Description of the Drawings
[0009] Figure 1 It is a schematic structural diagram of the utility model.
[0010] In the figure: 1 - lower pressure roller, 2 - hot or cold pressing roller, 3 - cold pressing roller, 4 - upper pressure roller, 5 - film. Detailed Embodiment
[0011] The technical solutions in the embodiments of the present utility model will be clearly and completely described below in conjunction with the accompanying drawings in the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments in the present utility model without creative efforts shall fall within the protection scope of the present utility model.
[0012] As Figure 1 shown, the S-roller double-pressure multi-functional pressing and traction structure includes a temperature-controlled S-roller, an upper pressing roller 4, and a lower pressing roller 1. The temperature-controlled S-roller includes a cold pressing roller 3 and a hot or cold pressing roller 2. The cold pressing roller 3 is located below the upper pressing roller 4, and the hot or cold pressing roller 2 is located above the lower pressing roller 1.
[0013] When used for lamination, the air cylinder drives the lower pressing roller 1 to move upward close to the hot or cold pressing roller 2. At the same time, the upper pressing roller 4 is in a lifted state and away from the cold pressing roller 3. The film 5 to be laminated passes through the hot or cold pressing roller 2, the lower pressing roller 1, and the cold pressing roller 3 in sequence to complete the lamination, and finally enters the winding unit below. A cold medium is introduced into the cold pressing roller 3, and a hot or cold medium is introduced into the hot or cold pressing roller 2 according to different process requirements.
[0014] When coating, the air cylinder drives the upper pressing roller 4 to move downward close to the cold pressing roller 3. At the same time, the lower pressing roller 1 moves downward away from the hot or cold pressing roller 2. The coated film 5 passes through the hot or cold pressing roller 2, the cold pressing roller 3, and the upper pressing roller 4 in sequence. The upper part of the coated film 5 is the coated surface. If it contacts the lower pressing roller 1, the coated surface will be damaged. The upper pressing roller 4 presses on the back surface (the uncoated surface) of the coated film. At this time, the upper pressing roller 4 plays a role of traction and flattening (the upper pressing roller 4 will not contact the coated surface, thus protecting the coated surface), flattening the coated film and making the coating effect better. The present utility model improves the lamination unit of a dry laminator and a solventless laminator, sets a double-pressing roller structure, and adds a coating function.
