The present invention relates to an apparatus for restoring the straightness of a precision filter for filtering high density chemical fibers, and a device for restoring the straightness of the precision filter for filtering high density raw materials for removing straight wave without damaging the microfiltration membrane to form a straightness. It is about.

Generally, the filter for filtration of high density fiber is composed of 5 layers of precise sintered gold mesh, and has an outer diameter of 14mm and a length of 1,000mm, and the inside is formed into a thin and long tubular shape with an empty space, and the side seam is heated at high temperature. It was to be precision welded.

However, the filter for filtering the high density chemical fiber raw materials as described above is formed to form a long tube shape by precise welding the side line seams at a high temperature, so that warpage occurs in the longitudinal direction after welding, and is also introduced into the high pressure, high temperature, high viscosity process of chemical fiber manufacturers. Even after use, the refraction caused by the length of the filter for filtration occurred.

Conventionally, when the longitudinal warpage of the filter for filtering the high-density fiber raw material as described above occurs, it is equipped with a high level of technical proficiency so as not to damage the filtration membrane portion of the filtration filter organized by a precise manual mesh, that is, by a skilled worker. A few skilled workers restored the straightness of the filter for filtration. In other words, by using a straight jig to hold the partial straightness with the hydraulic press to form the overall straightness, the operator places the straight tool and visually identifies the straightness by adjusting the partial bending and flatness with the safety hammer to form the straightness. It was supposed to be.

However, since the restoration of the straightness is performed by a person, a difference occurs in the straightness of the filter depending on the condition of the skilled person, the influence of the external environment, and a mistake according to the day. Damage and partial bending and deformation of the filter outer diameter caused a problem that the quality is reduced.

In addition, since the work must be performed by a highly skilled person, the labor cost is increased, mass production is impossible, and there are various problems such as a shortage of labor due to the lack of skilled person.

The present invention has been made in consideration of the above problems, and the object thereof is to automatically and straightly filter without damaging the filtration membrane by contacting a plurality of rollers arranged horizontally and vertically and alternately arranged in a cylindrical filtration filter outer peripheral surface. It is to provide a straightness restoration device of the precision filter for high-density fiber raw material filtration that can be restored.

The vertical contact roller 10 is an idle roller, which is installed to be rotatable to the base 50 by the support 12, and has an idle gear 14 rotated along the rotation shaft 13 therein. A contact groove 11 having the same radius as the outer surface radius of the filtration filter 30 is formed along the outer surface. The vertical contact roller 10 has a pair of two vertical contact rollers 10 arranged on the upper and lower parts so as to be located on the same center line, and the rotary shaft 13 of the vertical contact roller located at the lower side is supported. It is made to move up / down by the elasticity of the spring 15 provided in (12).

That is, the vertical contact roller 10 is arranged in a line up / down in the support 12 is fixed to the base 50, the outside of the cylindrical filter in the contact grooves 11 of the vertical contact rollers arranged in the upper and lower portions, respectively The surface is in contact with each other, and the vertical contact roller installed at the bottom is in close contact with the vertical contact roller installed at the top by the elasticity of the spring 15 so that the filtration precision filter and the up / down vertical contact roller 10 are in close contact with each other.

The horizontal contact roller 20 is rotated by receiving the driving force of the motor 40 by the chain 41, to the base 50 to form a perpendicular relationship ('+' shape) with the vertical contact roller 10 It is installed in the fixed support 22, has the same shape as the vertical contact roller 10, and the horizontal contact rollers located on both left and right sides form a pair, and a pair of horizontal contact rollers into the contact groove 21 The filter outer surface of the phase is intended to be in contact.

The pair of vertical contact rollers 10 and the pair of horizontal contact rollers 20 are each installed alternately, and the pair of horizontal contact rollers 20 and another pair of horizontal contact rollers 20a located nearby. The interval between them is subdivided into lengths fmf 80-100 mm of the filter 30 to have a smaller length. That is, the horizontal contact roller 20 is driven by the motor 40, but since the vertical contact roller 10 does not have a separate driving means, the inserted filter 30 is driven by the driving force of the horizontal contact roller 20. It is supposed to be moved.

In addition, the center line of the circular space formed by the contact grooves 11 of the pair of vertical contact rollers and the contact grooves 21 of the pair of horizontal contact rollers coincide with the center line of the filter moved in contact with the contact grooves. Vertical and horizontal contact rollers are provided respectively so that the center line of the circular space formed by the contact grooves of the pair of vertical and horizontal contact rollers coincides with each other. That is, the inner diameter of the circular space formed by the contact grooves of the pair of vertical / horizontal contact rollers is equal to the outer diameter of the filter.

According to the present invention configured as described above, the driving force of the motor is simultaneously transmitted to the plurality of horizontal contact rollers located on one side of the pair of horizontal contact rollers through the reducer, and the horizontal contact roller is driven by the driving force of the motor. When the filter is inserted between the left and right horizontal contact rollers (in a pair of vertical / horizontal contact rollers) as the horizontal contact roller is driven, the contact grooves of the left and right horizontal contact rollers come into contact with the upper and lower outer surfaces of the filter. This causes the left and right partial refractions of the filter to be unfolded, and the filter is moved in the forward direction to be moved into the contact grooves of the pair of vertical contact rollers. At this time, the vertical contact roller located at the bottom of the pair of vertical contact rollers are in close contact with the upper direction by the elasticity of the spring, so that the contact grooves of the vertical contact roller and the upper and lower outer surfaces of the filter are in contact with each other. This causes the upper and lower portions of the filter to be refracted.

The roller size is installed by precision processing to maintain a narrow gap of about 80-100 mm to prevent damage to the filter's 5-20 micron precision media fabric, and the rotation speed of the roller is about 1,500 to 2,000 m / m. .

Since the vertical / horizontal contact rollers are each 5-10 sets, that is, a plurality of 10-20 sets are repeatedly installed, the filter passing through the plurality of vertical / horizontal contact rollers has a number of vertical and horizontal refractions multiple times. To be adjusted over and over again.

As described above, the present invention is to adjust the up / down / left / right refraction of the filter by 10-20 vertical / horizontal contact rollers in the longitudinal direction of the object filtration filter, so that the straightness of the roller contact groove is provided. The surface contact of the filter prevents damage to the raw material of imported raw materials, and prevents deformation of the appearance, thereby reducing the defective rate and extending the life of the filter by scientific and rational straightness shape restoration.

In addition, since the straightness of the filter is automatically restored, mass production is possible, and production efficiency can be improved.
