The present invention relates to a laminator's heater device configured to combine both continuous work and single acting work one by one during laminating.

In more detail, the heat generated from the heating wire wound directly on the outer circumference of the first and second heating rolls of the laminator is directly heated from above and below the laminating material, and the extrusion lock is laminated on the first and second heating rolls. The material is not heat-welded properly, while the heat-welding again, the whole material comes out as a hard laminating product having a gloss, and at this time, it relates to a heater device of a laminator capable of various surface treatments according to the pattern of the pressing roll.

The heater device of the conventional laminator, as shown in the fifth diagram, covers the outer periphery of the iron pipe 1 with the silicon 2 and the inside of the iron pipe 1 is a heating roll 5 having a heater rod 4 therein. 3) was rotated. This is because the heat of the heater rod 4 is transferred to the silicon 2 coated on the outer circumference of the iron pipe 1 so that the heating roll 5 is laminated inside the iron pipe 1 to obtain a constant temperature. As the heating rod 4 is maintained at a high temperature, there is a lot of heat loss and the peripheral device receives unnecessary high heat, and in order to use the laminator, it takes a preheating time (about 8 to 14 minutes) of the heating roll 5. There was a problem that the waste of power is severe, the life of the heater is shortened.

The present invention has been devised to solve the above-mentioned problems and described by the accompanying drawings as follows.

In the accompanying drawings, 6 and 6a are first heating rolls which support both ends of the roll shafts 7 and 7a with the bearing 8, and on the outer periphery of the roll shafts 7 and 7a of (6) and 6a. After coating with the primary silicon 9, the heating wire 10 is wound thereon, and the secondary silicon film 11 is again coated thereon to form a heating roll.

12 is a power supply terminal connected to the heating wire 10, the brush 13 is attached to the outer periphery of the power supply terminal 12 to supply the storage to the heating wire (10).

14 and 14a are compression rolls. Both ends of the roll shafts 15 and 15a are supported by bearings 8a, and the outer edges of the compression rolls 14 and 14a have patterns 16 having various shapes. It may be formed.

18 and 18a are 2nd heating rollers, and since this 2nd heating rolls 18 and 18a have the same structure as the 1st heating rolls 6 and 6a, the description is abbreviate | omitted.

19 is a tooth in which the first heating roll 6a is provided at one end of the second heating roll 18a and the roll shafts 7a and 15a of the compression roll 14a, and the first heating roll 6a and The gear 19 provided on the roll shaft 7a of the second heating roll 18a rotates in engagement with the gear 22 of the motor and rotates between the roll shaft 15a of the compression roll 14a and the second heating roll 18a. The gear 19 provided on the roll shaft 7a meshes with the idle gear 23 to rotate the compression roll 14a.

Referring to the effect of the present invention configured as described above are as follows.

First, when the power is turned on for laminating, the roll shaft 7 is moved through the brush 13 of the power supply terminal 12 fixed to both ends of the first heating rolls 6 and 6a and the second heating rolls 18 and 18a. , 7a) Since the electric current flows through the heating wires 10 in the silicon films 9 and 11 coated on the outer periphery, and this heat directly laminates the surface of the silicon film 11, there is no loss of heat. Since the conduction time is short and the heater of the laminator does not need to be heated to a high temperature, the life of the heater is long and the lamination can be performed within 40 seconds or 1 minute after the power is turned on.

In addition, compared to the preheating time (for example, 8 minutes to 14 minutes) of the conventional heating roll 5, the present invention can shorten the preheating time (about 40 seconds to 1 minute), thereby reducing power consumption. When the first and second heating rolls 6, 6a, 18 and 18a are brought to a constant temperature, the present invention puts the laminating material (hereinafter referred to as material) between the first heating rolls 6 and 6a. Since the material is directly heated on the surface of the silicon film 11 of the first and second heating rolls 6, 6a, 18, and 18a, the material is heat-welded and the parts that are not completely welded are the compression rolls 14 and 14a. ) Is completely welded on the surface of the compression roll 14, 14a according to the pattern of the pattern (16) of various surface treatment (matte, diamond type, frosted foot, etc.) and beautiful, durable, glossy, hard plate-like Laminate products are formed.

As described above, since the present invention generates heat directly on the surface of the silicon film 11 of the first and second heating rolls 6, 6a, 18, and 18a, the preheating time is short and there is no need to generate high heat. It can minimize the high temperature interference on peripheral devices and can also use the compression rolls according to the pattern shape of the compression rolls (14, 14a), so that they can be laminated in various patterns and high quality laminating products are continuously and quickly. There are effects that can be done.
