Abstract

A hot melt adhesive label coating device without backing paper comprises a machine frame, a coating mechanism arranged on the machine frame, a cooling roll arranged on the machine frame of an output side of the coating mechanism, a plurality of guide rolls arranged on the machine frame and used for guiding base materials and surface materials, a base material unwinding roll, a base material winding roll, a surface material unwinding roll and a plane material winding roll, wherein the base material unwinding roll, the base material winding roll, the surface material unwinding roll and the surface material winding roll are arranged on the machine frame. Base materials on the base material unwinding roll pass through the coating mechanism and the cooling roll to be compounded with surface materials, then the base materials are separated from the surface materials, and at last the base materials are winded by the base material winding roll. The surface materials are compounded with the base materials on the output side of the cooling roll, then the surface materials on the surface material unwinding roll are separated from the base materials, hot melt adhesives are transferred from the base materials to the surface materials, and at last the surface materials are winded by the surface material winding roll. The hot melt adhesive label coating device without the backing paper is applied to production of a hot melt adhesive label without the backing paper and with temperature-sensitive surface materials, and can reduce the size and production cost of the hot melt adhesive label.

Description

A kind of no base stock PUR label apparatus for coating

Technical field

The utility model relates to a kind of PUR apparatus for coating, especially a kind of no base stock PUR label apparatus for coating.

Background technology

In the production technology of PUR label, adopt coating machine directly PUR to be coated on rolling moulding then on the label plane materiel usually; For the temperature-sensitive plane materiel that can not directly contact with dispense tip; Then need adopt base material (base stock) to carry PUR in advance; With the compound rolling then of temperature-sensitive plane materiel moulding, the interpolation of base material not only causes PUR label volume to increase but also increased the cost of PUR label after supercooling.

Summary of the invention

The purpose of the utility model is the deficiency to prior art; A kind of no base stock PUR label apparatus for coating is provided; Be applicable to and produce no base stock hot melt label, can reduce the volume and the production cost of hot melt label with the temperature-sensitive plane materiel that not directly contacts dispense tip.

The purpose of the utility model realizes through following technical scheme:

A kind of no base stock PUR label apparatus for coating; Comprise frame, be arranged at the coating mechanism on the frame; It is characterized in that: also comprise the chill roll that is arranged on the coating mechanism outlet side frame, be arranged at being used on the frame guide base material and plane materiel some guide rollers, be arranged at base material let off roll, base material wind-up roll, plane materiel let off roll and plane materiel wind-up roll on the frame; Base material on the base material let off roll is through separating then by the rolling of base material wind-up roll behind coating mechanism and the chill roll with behind compound one section of the plane materiel, and the plane materiel on the plane materiel let off roll separates behind compound one section of chill roll outlet side and base material makes PUR transfer on the plane materiel then by the rolling of plane materiel wind-up roll from base material.

Further, the utility model comprises that also being arranged at the composite log facestock and the base material that are used on the frame at base material and plane materiel carries out the cutting mechanism of deburring and be arranged at the waste material wind-up roll that is used to collect the waste material after the cutting mechanism post processing on the frame.

Further, said frame is provided with base material deviation correction mechanism and plane materiel deviation correction mechanism.

The utlity model has following beneficial effect:

During work, coating mechanism is coated on PUR on the base material, and is compound with plane materiel through chill roll cooling back then; Base material separates with plane materiel PUR is transferred on the plane materiel after compound one section; The rolling separately of base material after the separation and plane materiel, thus no base stock PUR label produced with temperature-sensitive plane materiel, compared with prior art; The base material of the utility model is reusable, reduces cost, reduces PUR label volume greatly; Composite log at base material and plane materiel is provided with cutting mechanism, can be used for facestock and base material and carries out deburring, improves the quality of PUR label.

Description of drawings

Below in conjunction with accompanying drawing the utility model is done further detailed explanation.

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

The specific embodiment

With reference to shown in Figure 1; A kind of no base stock PUR label apparatus for coating; Comprise frame 1, be arranged at coating mechanism 2 on the frame 1, be arranged at chill roll 3 on the coating mechanism 2 outlet side frames, be arranged at being used on the frame 1 guide base material 5 and plane materiel 4 some guide rollers 7, be arranged at base material let off roll 51, base material wind-up roll 52, plane materiel let off roll 41 and plane materiel wind-up roll 42 on the frame 1, be arranged at composite log 9 facestock 4 and the base material 5 that are used on the frame 1 at base material 5 and plane materiel 4 and carry out the cutting mechanism 8 of deburring and be arranged at the waste material wind-up roll 61,62 that is used to collect the waste material after cutting mechanism 8 post processings on the frame 1, frame 1 is provided with base material deviation correction mechanism 53 and plane materiel deviation correction mechanism 43.

Base material 5 on the base material let off roll 51 is through separating then by 52 rollings of base material wind-up roll behind coating mechanism 2 and the chill roll 3 with behind compound one section of the plane materiel, and the plane materiel 4 on the plane materiel let off roll 41 separates after compound one section at chill roll 3 outlet sides and base material 5 makes PUR transfer on the plane materiel 4 then by 42 rollings of plane materiel wind-up roll from base material 5.

The above; Be merely the utility model preferred embodiment; So can not limit the scope that the utility model is implemented with this, the equivalence of promptly doing according to the utility model claim and description changes and modifies, and all should still belong in the scope that the utility model patent contains.
