Abstract

The utility model disclose a PU (Polyurethane) local coating separated transfer apparatus, comprising: 1) a carrier for bearing PU adhesive; 2) a size applicator for locally coating PU adhesive on the carrier to form a PU local coating; 3) a transfer apparatus for tightly combing the carrier with the PU adhesive and fabric so as to stick PU adhesive on the fabric; 4) a drying apparatus for sticking and solidifying the PU adhesive on the fabric; 5) and a separating apparatus for separating the carrier from the baric. The PU local coating separated transfer apparatus adopts the carrier so that the PU adhesive is successfully stuck on the fabric by solidifying, thereby providing brittle fracture resin which can greatly influence the physical and chemical properties of products in the transfer process and resolving the problem of low product crockfastness and bad weatherability. The PU local coating separated transfer apparatus has simple structure and low manufacture cost, which can greatly improve the production efficiency of leather fabric and improve the ventilation property and weatherability of fabric.

Description

The release transfer device of the local coating of PU

Technical field

The utility model belongs to field of textile machinery, and it is release specifically to belong to the local coating of a kind of PU

Transfer device.

Background technology

On the market in the existing product, use several technologies to obtain the imitation leather fabric, as direct coating, transfer coated method, gold stamping method, these process characteristics are obvious, product has its advantage, but the problem that yet exists some to be difficult to fundamentally solve is not good as direct coating product feel, gas permeability is poor, can not obtain the flower type.Transfer coated method cost height; gas permeability is also bad; and to environmental protection formation pressure; gold stamping method also can be produced the imitation leather fabric with colored type; but because the limitation of technology; its surface has the embrittlement resin that one deck has a significant impact the product physical and chemical performance mostly, and the crock fastness of product is low, and weather fastness is poor.Address these problems and obtain desirable imitation leather fabric, need to use the device of the release transfer of the local coating of PU, but this type of desirable device is not arranged in the industry at present as yet with colored type.

Summary of the invention

Technical problem to be solved in the utility model is: the device of the release transfer of the local coating of a kind of PU is provided, and this device utilizes carrier, and local coating is release is transferred on the fabric with PU, to obtain the imitation leather fabric with PU flower type.

In order to solve the problems of the technologies described above, the utility model by the following technical solutions: the release transfer device of the local coating of a kind of PU is characterized in that it comprises: 1) carrier: be used to carry PU glue; 2) size applicator: be used for PU glue part is coated on carrier, form the local coating of PU; 3) transfer device: be used to make carrier and PU glue thereof and fabric to combine closely, allow the PU glue bond on fabric; 4) drying unit: be used for the PU adhesive curing and be bonded in fabric; 5) separator: be used to make carrier to separate from fabric, more than each device be connected in turn.

By above technical scheme as can be known, the utility model has adopted carrier, play PU glue is transferred to transfer function on the fabric from size applicator, PU glue successfully is cured to be bonded on the fabric, it does not provide the embrittlement that the product physical and chemical performance is had a significant impact resin this transmittance process, therefore the product crock fastness is low, and the problem of weather fastness difference is solved.The utility model is simple in structure, and low cost of manufacture can increase substantially the production efficiency of imitation leather fabric, improves gas permeability, the weather fastness of fabric.

Description of drawings

Fig. 1 is a structural representation of the present utility model

The specific embodiment

Referring to Fig. 1, the utility model comprises: carrier 1, size applicator 2, transfer device 3, drying unit 4, separator 5, more than each device be connected in turn.

PU glue 9 is abbreviations of polyurethane resin in the utility model, and this resin can be solvent type or water-based, can be a liquid type or two-liquid type, must have printing performance preferably, can bond together with fabric, have film forming.

Carrier 1 effect is the PU glue that carrying size applicator 2 is executed, and it also has release ability simultaneously, and when PU glue was transferred on the fabric 6 on carrier 1, carrier 1 can be easily separated.Carrier 1 is as material important in the utility model, a kind of carrier that the utility model adopts has the release liners similar performance of using in the transfer coated method, it has release ability, but can in release process, do not separated by embrittlement, from the principle, it is an intermediary, plays PU glue is transferred to transfer function on the fabric 6 from size applicator 2.And it does not provide the product physical and chemical performance is had a significant impact the embrittlement resin in this process, so the product crock fastness is low, and the problem of weather fastness difference is solved.In the utility model, this carrier can be polyester film or the release liners that the surface of the extraordinary organosilicon processing of a kind of process scribbles mould release, also can use silicone rubber belt, and perhaps bulging face or the conveyer belt made from stainless steel material formed.

Size applicator 2 is used for PU glue part is coated on carrier 1, form the local coating of PU, in the utility model, be called as printing equipment, use the printing equipment in the printing industry, as cylinder, plain net device, intaglio plate or direct spraying (air brushing) device all are feasible on principle, but because the particularity of PU glue, guarantee stable and decorative pattern complete of applying glue process, need to adjust printing equipment and make its anti-solvent, and keep the flowability of PU glue.And printing equipment deinkings such as intaglio plate must take into account the extension performance of ink of carrier.

Transfer device 3 makes carrier 1 be with PU glue and fabric to combine closely, and allows the PU glue bond on fabric 6; Can pressurize mutually with the circle drum makes carrier 1 have the face of PU to combine with 6 in fabric, and transfer device 3 adopts the pressure roller 7 and the bearing roller 8 of pressurization mutually in the present embodiment.In cohesive process, can adopt the method for colding pressing, also can adopt the method for hot pressing.

Drying unit 4 is bonded on the fabric 6 the PU adhesive curing.Rouse as drying unit with the big circle of heating in the utility model, this device can keep certain pressure (i.e. the way that is incubated with the blanket band) to fabric 6 and carrier 1 in drying course, and drying unit 4 also can carry out with baking oven.

Separator 5 intactly separates carrier 1 from fabric 6, and PU glue is stayed on the fabric 6, and PU glue is intactly stayed on the fabric 6 when keeping separating, and can also can use cold separation with thermal release, depends on the performance of carrier 1 and the style of product.
