The present invention relates to a knife drum for cutting the edge portion of the sheet strip produced in the sheet production equipment, and more specifically has an internal gap adjustment function that can be automatically adjusted without the need of a separate device equipped with its own gap adjustment function inside the device It relates to a knife drum device equipped with.

In general, the cutting of the strip edge in the conventional working method is made by a device configured in the shape as shown in FIG. Such a device is commonly referred to as a side trimmer, and the side trimmer rotates the cutting knife on the knife drums 30 and 31 installed at one end of the shaft when the drum shaft is rotated by the rotation of the drive gear that receives the motor's power. It is configured to continuously cut the strip edge portion that proceeds between them.

These side trimmers have to adjust gaps and wraps according to the thickness of the strip, respectively, so that the edge edge of the strip is beautiful and a good quality product is produced without scratching the strip surface and various driving shafts. Current gap and lap adjustments can be cut without problems if the undulation of the strip thickness of the lap does not occur in the adjustment, but the gap adjustment is sensitive to the production of stainless steel products rather than ordinary steel. Due to this problem, the gap is adjusted using the inner and outer adjusting nuts 32 and 33 before the stripping of strips having different thicknesses.

In the gap adjustment, when the gap is enlarged, the outer and inner adjustment nuts are relaxed by using the adjustment tool, and then rotated to the fixed plate side. To make the gap smaller, the adjustment is reversed. After this operation, the gauge is inserted between the upper and lower knives to measure the gap. If the correct gap does not come out, repeat the adjustment. After adjusting the gap in this way, the inner and outer adjustment nuts are fixed to the fixing plate side so that the adjustment nuts do not move. When the gap is adjusted by these operations, it is difficult to precisely adjust the gap due to the repetition of the work and the insertion and removal of the bearing thrust in the tight insertion of the signature gauge. Occurs frequently. In addition, damage to the fixing plate may occur due to excessive tightening of the inner and outer fixing nuts to eliminate the movement of the adjusting screw after adjusting the gap. The frequency of repair work is increased due to such work defects and difficulty of precise adjustment, which leads to an increase in maintenance cost and shortening of equipment life, resulting in many product defects. For reference, when the lap adjustment handle 34 is rotated as shown in FIG.

The present invention has been made to solve the above problems, the object of which is to form a device with a gap adjustment function in its own, it is possible to confirm the formation of the gap through the electrical signal in the cab continuously operation is possible To provide a knife drum device with an internal gap adjustment function.

In order to achieve the above object, the present invention provides a knife drum device for cutting a strip edge portion, an operation unit capable of operating a knife drum gap adjustment, and a gap adjustment unit capable of fine amount gap adjustment operation by movement of the operation unit. And it provides a knife drum device having an internal gap adjustment function consisting of a fixing portion for removing the gap after the gap adjustment.

Hereinafter, the present invention will be described in more detail with reference to the embodiments illustrated in the accompanying drawings.                     

The knife drum device with an inner gap adjustment function according to the present invention has an inner gap adjustment operation portion as shown in Fig. 3, which acts from the outside inside the upper knife drum shaft 4 formed on one side of the side trimmer. Flow paths 10 and 11 which are hydraulic oil pressure pipes which are introduced are formed through. The inside of the upper knife drum shaft has a hollow shape in the other side of the end of the flow path (10, 11) fixed cap 12, after which the non-elastic elastic member 13 is installed, a predetermined distance therefrom the flow path ( The distal end of 10) (11) is formed in communication with the inner shaft part.

In addition, the jude 14 is formed long in the axial direction from the non-elastic elastic member 13, and the auxiliary rod 15, which is an adjusting portion, is inserted into the outer side thereof. The adjusting part is provided with a horizontal sliding operating member 16 at the end of the auxiliary rod 15 by the fixing member 17. The horizontal sliding operation member 16 has a circular outer shape with a taper shape, and sliding grooves 16-1 are formed at both sides thereof. In addition, the vertical sliding operating member 18 is inserted into the sliding groove 16-1 and moved in the vertical direction. The vertical sliding operation member 18 is formed in a member-like shape, the elastic guide lamp 19 is installed in the upper center and the elastic member 20 is inserted into the outside.

The fixing part inserts and installs the sliding guide member 22 on the rod extending from the jude 14, and then inserts the upper knife drum 7 on the outside thereof, and fixes the fixing member 26 to the end of the jude 14. Tighten to secure.

The sliding guide member 22 has a tapered surface in contact with the vertical sliding operating member 18, and a jude 14 insertion hole is formed at the center thereof, and the guide member fixing member 25 is formed at an outer side thereof. The outer end portion 22-2, which can be latched on the inner side, has an inner end portion formed therein, and the sliding guide drum 24 is fixed integrally by the plurality of fixing members 23 on the outer side surface.

In the above configuration, as shown in FIG. 5, when the gap of the knife drum is reduced, when the oil is supplied to the gap reduction passage 11, the oil is formed between the auxiliary rod 15 and the jude 14. The auxiliary rod 15 is pushed back in two directions, which raises the vertically sliding vertical sliding operation member 18 in three directions, which is in contact with the sliding guide member 22 while compressing the elastic member 20. This allows a fine gap to be formed. An oil pressure for pushing the jude 14 in four directions is formed through the minute gap, and the pressure is pushed against the uncompressed elastic member 13, thereby closely contacting the horizontal sliding operating member 16 and the sliding guide member 22. This narrows the gap due to speech formation with the knife drums 6, 7.
In addition, as shown in FIG. 6, when oil is supplied to the gap enlargement flow path 10, a force is applied to push the jude 14 on the auxiliary rod 15 in the B direction, and thus the unpressurized elastic member 13 is applied. Is compressed and the horizontal sliding member 16, which is extended with the auxiliary rod 15, moves to B ', which slides while the vertical sliding operating member 18 in sliding contact is moved by the elastic member 20 in the C direction. The guide member 22 is moved in the D 'direction. This operation enlarges the gap of the knife drums 6, 7.

delete

As described above, the oil supply through the gap enlargement flow paths 10 and 11 allows the knife drum gap to be enlarged and reduced, and this gap adjustment operation is measured by a sensor.

 According to the present invention as described above, the use of a knife drum device with an internal gap adjustment function enables efficient gap adjustment in the cab without the need for special tools or other measuring devices, so that accurate gap adjustment is possible and efficient work is possible. It is possible to improve productivity and enable safe work.
