Figure 4 is a (a) (b) is an operating state of the present invention.

The present invention relates to a pressure regulating device with a roll of a laminator, and more particularly, to allow the bearing of the heating roller and the delivery roller to be moved up and down by a cam on which a handle is attached, and to the adherend passing through each roller. The emphasis was on not only applying uniform pressure, but also making the film replacement work smoother and faster.

In general, the laminator allows the film wound on the upper film roller and the lower film roller to pass through a pair of the heating roller and the pressing roller, and then guides and transports the deposit onto the guide plate, and passes between the heating roller and the pressing roller to form an image of the adherend. · Coating work on the bottom.

However, such a conventional laminator is installed so as to be pressurized only by the spring force accumulated in the pair of the heating roller and the pressing roller upper roll shaft, so that the heating roller and the feeding roller cannot pressurize the adherend uniformly, and thus between the adherend and the film. In addition to the problem that bubbles are generated, there was a problem that a uniform coating surface cannot be obtained.

In addition, when the upper and lower film rolls are replaced with different types of film rolls, or when used film rolls are replaced with new film rolls, it is very difficult to remove the film compressed between each heating roller and the feeding roller. There is a problem that requires time.

Therefore, the present invention is to solve the conventional problems as described above, an object of the present invention is to allow the upper and lower rollers of the heating roller and the delivery roller to be moved up and down by the variable bearing, the upper and lower It is possible to pressurize the film more uniformly, to prevent bubbles between the adherend and the film, and to provide a roller pressure regulating device of the laminator that can perform the film replacement operation more smoothly and steadily. .

Hereinafter, the roller pressure control device of the laminator according to the present invention will be described in detail with reference to the accompanying drawings.

A heating roller mounting hole 302 and a delivery roller mounting hole 303 are formed in each of the side walls 301 of the laminator 300, and the lower shaft 102 of the pair of heating rollers 100 is inserted into the outer side thereof. Heated roller lower roll bearing 10 having a long hole 11 to be rotated is coupled, the lower roller feeder having a long hole 21 is inserted into the lower shaft 202 of the feed roller to the outside of the delivery roller mounting hole Roll bearing 20 is installed, the upper portion is bent to form a seating portion 34, the heating roller shaft guide hole 32 and the discharge roller shaft guide hole 33 on the other side, the central portion thereof The movable plate 30 having the cam insertion hole 31 formed thereon is fixed to the heating roller lower roll bearing 10 and the delivery roller lower roll bearing 20, so that the shaft hole is eccentric with the cam insertion hole 31. The formed cam 40 is inserted, and the cam shaft 41 is inserted therethrough to penetrate both side walls 301 of the laminator to form a shaft hole of another cam. Bond is, the cam shaft 41 protruding to one side tip of the handle 42 is provided with coupling.

Then, the heating roller upper shaft support 12 and the delivery roller upper shaft support 22 are coupled to the seating portion 34 of the movable plate 30 by the guide rod 50 on which the spring 51 is mounted. Among the same roller pressurizing device, one side of the heating roller upper bearing 12 and the lower bearing 10 is provided with a voltage connecting pin support bracket 14 for applying power to a heating wire in the pair of heating rollers 100.

The present invention constituted as described above inserts the shafts of each of the pair of heating rollers 100 into the heating roller lower shaft insertion hole 11 and the upper shaft insertion hole 13.

At this time, one side of the heating roller 100 is to be in contact with the connecting plate installed in the power connection bracket 14 so that power is applied to the heating wire embedded in the roller.

Then, a pair of feed rollers 200 each side is inserted into the feed roller lower shaft insertion hole 21 and the feed roller upper shaft insertion hole 23.

In this state, as the laminator is driven, the heating roller 100 and the delivery roller 200 are driven to rotate, respectively, and the heating wire in the heating roller 100 is heated in contact with the power connecting plate and inserted into the heating roller. The film is heated to be thermally fused to the upper and lower surfaces of the adherend, and the adherend is transferred to the delivery roller side, and the transferred adherend is finally drafted between the delivery rollers 200.

At this time, when pressurizing the adherend to be transported between the rollers according to the thickness of the film heat-sealed to the adherent more strongly coupled to the camshaft 41 by rotating the handle 42 installed on one end of the camshaft 41 Each cam 40 in contact with the outside of the laminator both side walls 301 is rotated in the cam insertion hole 31 formed in the center of the movable plate 30, so that the long side of the cam 40 is cam insertion hole. Located in the lower end of the 30, thereby moving the movable plate 30 is pulled down the guide rod 50, which is loaded with the spring 51 on the seating portion 34, thereby pulling the heating roller upper bearing ( 12) and the short-circuit force of the spring 51 is applied to the upper roller bearing 22, the upper heating roller 101 and the upper feeding roller 201 is to compress the adherend more strongly.

Then, in order to remove the film sandwiched between the heating roller 100 and the delivery roller 200 during film roll replacement, the handle 42 is rotated so that the upper side of the cam 40 is positioned above the cam insertion hole 31. When rotated, the movable plate 30 plate is moved upward, and the heating roller upper bearing 12 and the feeding roller upper bearing 22 coupled to the seating part 34 are moved upward, respectively, and a pair of heating rollers 100 and Between the delivery roller 200 is to be able to remove the film is spaced apart.

At this time, the heating roller lower shaft 102 and the delivery roller lower shaft 202 is located in each guide hole (32, 33) formed on both sides of the movable plate 30 to have no movement change.

As described above, according to the roller pressure adjusting device of the laminator according to the present invention, it is possible to always apply uniform pressure regardless of the thickness of the adherend and the film thickness, and also to quickly replace the film sandwiched between the rollers when the film roll is replaced. It is a very practical design that can be separated and removed.
