Field of the Invention [0001] The present invention relates to a dust removing apparatus for a plexiglass laminating machine, and more particularly, to a plexiglass laminating machine which is mainly made of acrylic resin to maintain semi-permanent preservation while enhancing transparency and chroma And more particularly to an improved dust removing apparatus for effectively removing dust.

Prints that you want to remember and keep for a long time, including photographs, pictures, a certificate or a citation, are usually stored on a frame.

However, these prints are oxidized by contact with oxygen during storage for a long period of time, resulting in discoloration and damage to the original.

Various methods for solving this problem have been attempted. One of them has been disclosed in a publication No. 2013-0003188, in which a technique of attaching an acrylic plate silk-screen printed on the front face of a frame frame to prevent color fade and increase quality is disclosed There is a bar.

However, this method is not only troublesome and inconvenient to work, but also has a very low production efficiency and low competitiveness in terms of utility.

In this connection, acrylic laminating technology which realizes transparency and color saturation of plexiglass clearer than glass and prevents color blindness even after storage for a long time is implemented.

In this technique, a plexiglass such as a transparent acrylic plate is inserted from one side and a material such as a photograph is supplied to the upper side of the acrylic plate from the other side, and then the laminate is passed through the pressing roll while being in contact with each other.

This technology is capable of processing a large amount of bonded materials in a short period of time, which results in good mass productivity. Therefore, the technique is excellent in preventing discoloration because of its low cost and excellent bonding properties.

However, acrylic has a disadvantage in that it is easily adsorbed on fine dusts such as dust or the like, and thus the surface can be easily contaminated.

Therefore, bonding failure occurs when fine dusts are mixed in the process of applying an acrylic plate and applying an adhesive, or in the process of bonding an object to an acrylic plate coated with an adhesive.

However, there is no problem with re-workable workpieces if joining defects occur, but if the workpieces are the only ones that are very valuable, they can not be reworked, which leads to serious problems.

The present invention has been made in view of the above-described problems in the prior art, and it is an object of the present invention to provide a method of sealing a bonded object such as a photograph or the like to a bonding material such as an acrylic plate having a high transparency, The present invention provides a dust removing apparatus for a plexiglass laminating machine which can improve the quality of a laminating product.

Particularly, the dust removing unit 100 has a similar concept to a kind of cover, but maintains a level at which the open upper surface of the laminating main body 200 is almost sealed, leaving only a space into which the acrylic plate A is inserted, A clean room is formed on the opened top surface of the clean room 200.

The upper surface of the laminating main body 200 is provided with a pair of bonding rolls R 1 and R 2 which are vertically engaged as shown in FIGS. 1 and 4.

The pair of joining rolls R1 and R2 includes an acrylic plate A which enters from the front of the laminating body 200 and enters the rear of the laminating body 200, Which is to be joined while being pressed, while being passed through the material P to be joined such as a photo or the like.

At this time, an adhesive may be applied to the upper surface of the acrylic plate (A) in the width direction before the material (P) to be bonded is brought into contact with the upper surface of the acrylic plate (A).

In the present invention, the acrylic plate A is exemplified as a substrate to which the member to be joined P is bonded in a preferred embodiment. However, the acrylic plate A is merely an illustrative example, and polycarbonate (PC), polyethylene terephthalate PET, glass, a transparent acrylic film, and a thick acrylic film of 100500 different from the conventional ones can be used. As described above, if the substrate functions as a plexiglass which can increase transparency and saturation of the material to be bonded (P) Either is acceptable.

1 to 4, the dust removing unit 100 includes a pair of vertical plates 110 having an approximately 'a' shape conforming to the shape of the open top of the laminating body 200, Shaped sealing plate 120 fixed to the upper end and the front end of the vertical plate 110 to form a space therein and a rear portion of the dust removing unit 100 facing the sealing plate 120 (Not shown).

A door 122 may be further provided on the front surface of the sealing plate 120. The door 122 may be provided with an adhesive agent on the bonding surface of the acrylic plate A .

In this case, the door 122 may be configured to be loosened and tightened through a pair of fixing bolts B1 and B2. When the adhesive is applied after the release, the adhesive is applied, the door 122 is locked again to maintain the inside of the clean room Or < / RTI >

Alternatively, although not shown, the door 122 and the sealing plate 120 can be opened and closed by a spring, and can be opened and closed in a sliding manner or by a hinged door system.

Or the door 122 may be formed with a groove into which the door 122 can be inserted in a portion where the door 122 is located and the door 122 and the door 122 are inserted Respectively, and a spring is provided at the lower portion of the door so as to be semiautomatically closed.

In this case, when the door 122 is pushed downward, the latching groove and the protrusion are engaged with each other to open the door 122, and the spring can be kept in a contracted state.

When the door 122 is to be closed, the door 122 is pressed downward to release the engagement between the latching groove and the protrusion. At this time, due to the restoring force of the spring, 122 may be closed.

Further, although not shown, it is of course possible to provide a nozzle capable of reciprocating with a ball screw on the inside of the door 122, and to automatically deform the adhesive to be applied through the nozzle.

Alternatively, it is possible to design and modify the adhesive so that the adhesive is automatically applied through the nozzle by inserting the nozzle into the through-hole by forming 35 through grooves in the door 122, but the invention is not limited thereto.

Further, a filter F and a blowing fan BL may be further installed on one side of the upper surface of the sealing plate 120.

At this time, the filter (F) is a replaceable structure, preferably a Zephyr filter capable of hammering fine dust, and the blowing fan (BL) is installed on the upper surface of the filter (F).

Therefore, when the outside air is forcedly injected into the clean room, the fine dust contained in the outside air is collected by the filter F, so that the purified room is injected into the clean room for a purified clean space. After the injection, A) is discharged through the lower front side gap and the rear lower side gap which are discharged after being joined, so that the inflow of the external fine dust through the clearance can be completely blocked. That is, a positive pressure is applied to the inside of the clean room, so that the contaminated air from the outside does not flow into the clean room, and only air purified through the filter can be introduced into the inside through the blowing fan BL.

Particularly, the dust removing unit 100 formed by combining the vertical plate 110, the sealing plate 120, and the rear plate 130 is free from the upper surface of the laminating body 200 through the fixing member 190 Since it is installed so that it can be detached, it also improves convenience in use. Of course, at the lower ends of the vertical plate 110, the sealing plate 120, and the rear plate 130, where the dust removing unit 100 is partly removed from the opened upper surface of the laminating main body 200, A sealing material for improving the sealing function may be further attached.

A pair of fixing brackets 140 are fixed to the opposite inner sides of the pair of the vertical plates 110 with an interval therebetween and a cylindrical housing 150 is fixed to the fixing brackets 140 A lifting rod 152 is inserted into the cylindrical housing 150 to elastically move in the vertical direction with a spring 160 interposed therebetween. At the lower end of the lifting rod 152, washing rolls 170a and 170b So that it can be rotated.

One of the cleaning rolls 170a sweeps the upper surface of the acrylic plate A to prevent the fine dust from being adsorbed as much as possible by suppressing the generation of static electricity while the other cleaning roll 170b blocks the bonding And sweeps the surface of the water P.

At this time, the cleaning roll 170b can be used as a DCR roller or a general roller. The cleaning roll 170b can prevent the wrinkles of the printed material and smoothly press the joining material P and the joining rolls R1 and R2, This makes it possible to produce a clean product without wrinkles.

The cleaning roll here uses known rollers capable of removing static electricity and fine dust, and the removal of fine dust in the cleaning rolls can be removed in such a way that the cleaning rolls are cleaned with a cleaning or other cloth.

In addition, since the lifting rod 152 is elastically supported by the spring 160, even if the load increases, the tension can be automatically adjusted while buffering the lifting load without any problems.

In addition, an adjustment knob 180 may be further provided on the upper end of the cylindrical housing 150.

At this time, the cylindrical housing 150 is exposed to the outside through the upper surface of the sealing plate 120, and the adjustment knob 180 is provided at the exposed end, so that the cylindrical housing 150, So that the elasticity of the spring 160 can be controlled.

In this case, the cylindrical housing 150 should be screwed to the fixing bracket 140.

In addition, the adjustment knob 180 may be provided with a ring 185 having a predetermined thickness. The ring may be installed in the adjustment knob 180, or may be installed only in one adjustment knob 180 It is possible and not limited.

For example, as shown in FIG. 5 (b), by installing the loop 185 on the adjustment knob 180, the adjustment knob 180 is rotated to push down the cylindrical housing 150 So that the cleaning roll 170a can be prevented from reaching the floor.

When the material to be bonded or the acrylic plate is caught in the middle, the ring 185 is installed to raise the cleaning rolls 170a and 170b to the object P or the acrylic plate A, Can be smoothly pulled out.

The present invention having such a configuration has the following operational relationship.

When it is desired to produce the acrylic joint in the form of a laminate, the operator first places the acrylic plate A on the front side of the laminating main body 200 and places the material P on the rear upper side.

At this time, the dust removing unit 100 according to the present invention is mounted on the front side of the laminating main body 200.

Then, when power is applied to the laminating main body 200 to drive the bonding rolls R1 and R2, the blowing fan BL is rotated to supply outside air into the clean room.

Further, the acrylic plate (A) and the member (P) to be bonded are put in.

Then, the inside of the clean room is maintained in a clean state with no fine dust, and the upper surface of the acrylic plate A is cleaned first by the cleaning roll 170a, that is, the state where static electricity is not generated And similarly, the materials to be bonded P are also sweeped by another cleaning roll 170b and supplied in a cleaned state.

Thereafter, the material P to be joined is tightly adhered to the upper surface of the acrylic plate A in a state of being tensioned, and is finally laminated while passing through the pair of bonding rolls R1 and R2 in this state, Is completed.

Alternatively, when a long photograph is used, the acrylic plate and the member to be joined are formed into a roll shape, and a roll-shaped acrylic plate A is disposed in front of the laminating body 200, And a dispenser capable of discharging the adhesive in a predetermined amount can be provided to laminate a long-length photo picture or the like, thereby completing a single frame-type bonded product.

As described above, according to the present invention, the periphery where the acrylic plate A and the member to be bonded P are joined is made into a clean room empty space, the fine dust is prevented from entering into the empty space, The dust is completely discharged to the outside, and thus it is advantageous to completely prevent defects due to dust adsorption.
