Description

Paper Powder Removing Device for Paper-Making}

The present invention relates to a paper stock removal device, and more particularly, to a paper stock removal device configured to suck and remove a stake generated by cutting in paper processing.

In general, the paper made in the form of a roll (roll) in the paper factory is shipped through a paper processing process for processing to a specified standard in accordance with the needs of the consumer.

In the paper processing process, the paper is processed into a roll type or a flat plate type, which is smaller than before processing, and the paper is processed using a slitter, a turn knife, or the like.

In the paper processing process, a cutting knife is installed at a portion where the cutting of the paper is performed.

The cutting knife is mainly formed in a circular shape, performs a rotational movement, and cuts the paper as it comes into contact with the paper while staying or moving in one place, thereby generating a stake.

The stake generated by the knife for cutting is required to be removed because it causes various problems such as deterioration of paper quality and environmental pollution inside the workplace when left unattended.

An apparatus for removing a stake generated by a cut during a conventional paper processing process is Korean Patent Registration No. 10-0427011.

The patent registration No. 0427011 for the equity suction device for cutting machine is an external air supply line for supplying external air through a trim fan, a trim suction line piped to the slitter and turning knife and the end of which is connected to the ejector of the external air supply line, and external air supply At the same time it is connected to the line, the inlet is formed and includes a safety cover that covers the slitter and the turning knife.

However, the stake suction device for the conventional cutting machine as described above is difficult to completely surround the safety cover to the part where the cutting knife and the paper contact, and the equity is leaked to the outside of the safety cover by the gap between the safety cover and the paper. As the stakes remain in the easily cut part and the surrounding area, there are problems such as contamination of the workplace and deterioration of paper quality. Therefore, researches on the device that can effectively remove the stakes generated during cutting in the paper processing process. Development is required.

In addition, a device for removing the stake immediately after being cut together with the stake suction device for the cutting machine installed near the cutting knife and sucking the stake at the same time as the cutting is needed.

The present invention has been made in view of the above, it is possible to remove the stake more cleanly by brushing off the stake on the paper using a brush member and suctioning the stake through the suction hole when contacted with the cut and conveyed paper as a whole It is an object of the present invention to provide a paper stock removal device.

And another object of the present invention is to provide a paper stock removal device that is easy to collect and recycle the stake because it is possible to separate the suctioned stake in the dust collector.

The paper stock removal apparatus proposed by the present invention includes a roll brush which is installed rotatably on the paper cut by the cutting knife and removes the stake by performing suction while contacting the paper, and the suction force on the roll brush. The vacuum pump is connected and installed to generate a, and is installed between the roll brush and the vacuum pump is connected to the suction of the inside of the roll brush is made of a dust collector for separating and collecting the shares transferred to the vacuum pump.

The roll brush is formed in a cylindrical shape and has a suction space communicating with the dust collector around the inner circumferential surface, and a plurality of suction holes penetrating the inner circumferential surface and the outer circumferential surface are formed at regular intervals and rotated at a constant interval with the paper. And a brush member installed on the outer side of the body and possibly rotating in contact with the body to be in contact with the paper.

An extension shaft positioned at one end of the inner shaft cylinder of the body is formed in the connecting passage for communicating the dust collector and the suction space, the connecting passage is formed along the central axis line of the extension shaft and open to the end surface of the extension shaft It is formed by branching about 2 to 8 branches from the main passage and the open opposite side of the main passage and consists of a plurality of branch passages for communicating with the suction space, one end of the inner shaft cylinder is the branch passage and suction A plurality of through holes are formed at regular intervals along the circumference to communicate the space.

The brush member is formed in a band shape and comprises a fixing part fixed to the body, and the brush head is fixed to one end of the fixing part.

In the brush member is formed by forming a spiral along the circumference of the outer peripheral surface of the body, the plurality of suction holes formed in the body may be formed in a spiral arrangement in a state located between the brush member.

The dust collector is formed in a cylindrical shape having a lower end of the taper, and has a lower end surface, and a cyclone tube for separating and transferring the inflow downward, and a dust collector for collecting the equity installed in the lower portion of the cyclone cylinder and transported downward. It is made to include.

In the cyclone barrel is formed with an inlet port and the discharge port communicating with the suction space formed in the body of the roll brush, respectively.

And the present invention may further comprise a motor for transmitting a rotational force to the roll brush.

According to the paper stock removal apparatus according to the present invention, it is possible to remove the stake cleanly as a whole, since the paper is removed while a relatively uniform suction force acts on the paper as a whole.

In addition, according to the papermaking stake removing apparatus according to the present invention, since the suction of the stake is performed through the suction hole while the brush member separates the stake from the paper, the quality and cleanliness of the paper are further improved.

Further, according to the papermaking stake removing apparatus according to the present invention, the suction through the suction hole is performed while the suction hole and the paper surface are kept at a certain distance by the brush member, so that the suction performance can be improved.

Furthermore, according to the paper stock removal apparatus according to the present invention, since the stake to be sucked and conveyed is collected and the treatment of the stake becomes easy and simple.

Next, a preferred embodiment of the paper stock removal apparatus according to the present invention will be described in detail with reference to the drawings.

First, as shown in FIGS. 1 and 2, one embodiment of the paper stock removal apparatus according to the present invention includes a roll brush 20 rotating in the upper portion of the paper 2 cut to the cutting knife 10.
