The present invention relates to a circular knife detachment device of a side trimmer, and more particularly, by detaching the circular knife of the side trimmer while maintaining vertical and horizontal angles, thereby ensuring the quality after cutting both ends of the strip, The present invention relates to a circular knife detachable device of a side trimmer which can prevent the damage of a circular knife and safety accidents caused by dropping, as well as shorten the replacement time of the circular knife.

In general, as shown in Figure 1, the side trimmer is installed in the upper and lower pairs on both ends of the width direction of the strip (S) to adjust the width of the strip (S) by cutting both ends of the strip (S). As shown in FIG. 2, a circular knife 10 which contacts the strip S and cuts the strip S is coupled by the guide plate 12a of the fixed shaft 12 and the bolt 11b. In the cutting of the strip S, a fixing plate 11a having a nubbling ring 11 made of an elastic material such as rubber which suppresses the flow of the strip S is attached to the outside is the circular knife 10 and the bolt 11b. Composed by

Since the circular knife 10 is coupled to the fixed shaft 12, the fixed key 12b of the fixed shaft 12 is inserted into the key groove 10a of the circular knife 10, thereby rapidly rotating the circular knife 10. Edo circular knife 10 is firmly coupled without falling off, and the nubber ring 11 is bound to the outer side of the fixing plate (11a), the nubber ring 11 is on the nubber catching jaw (11c, see Fig. 5) It is configured to be firmly coupled without falling off from the fixed plate (11a).

As shown in FIG. 3, the side trimmer 100 configured as described above is moved to both ends of the strip S, and the upper and lower side trimmers 100 are spaced apart at predetermined intervals to the left and right sides. Position and close contact with the strip (S), so that the end of the strip (S) is cut by rotating the circular knife (10) configured in the upper and lower parts while the nubber ring (11) gripping the strip (S) do.

The side trimmer 100 is moved to both ends of the strip S by the trimmer moving table 20 (see FIG. 4) or spaced apart from the strip S, and the side trimmer 100 moves left and right. 4, the trimmer movable table 20 to which the side trimmer 100 is coupled is rotatably coupled to the rotating part 21 configured at the lower portion, and the driving part 22 configured at the lower part of the rotating part 21. Moves along the shaft gear 22 that is rotated by the motor 25 so that the side trimmer 100 moves left and right.

When disassembling the circular knife 10 and the nubber 11 for replacement by the wear of the circular knife 10 or maintenance of the side trimmer 100 in the side trimmer 100 configured as described above, the bolt 11b is removed. After disassembling to separate the fixing plate (11a) and dropping the nubber (11) from the fixing plate (11a) using a jig, the circular knife (10) is hit with a copper hammer to disassemble from the fixed shaft (12), When replacing the circular knife 10 and after the maintenance of the side trimmer 11 again, forcibly fitting the circular knife 10 to the fixed shaft 12 and then fixing the nub ring 11 to the fixed plate ( The 11a) is combined and fixed by the bolt 11b.

However, in the process of disassembling the circular knife 10 in the side trimmer 100, the circular knife 10 is dropped to the lower portion of the fixed shaft 12, so that the circular knife 10 may be damaged as well as a safety accident may occur. There is a danger, and as shown in Figure 5 and 6 in the coupling of the fixed plate (11a) to which the circular knife 10 and the nuber ring 11 is fastened to the fixed shaft 12, the circular knife (10) ), The working time is excessively increased as well as the clamping plate 11a on which the circular knife 10 and the nubber ring 11 are bound is coupled to the fixed shaft 12 in a state in which horizontal and vertical angles are not maintained. In this case, horizontal and vertical gaps G are formed between the upper and lower circular knives 10, and when the ends of the strips S are cut while the gaps G are formed, the cut portions of the strips S The width of the strip is adjusted by being partially attached to one side end of the strip S without being completely cut. There was such a problem that the quality of the (S) decreases.

The present invention is to solve the above-described problems, in particular, the present invention in contact with the fixed shaft of the side trimmer to remove the circular knife in a state in which the vertical and horizontal positions of the fixed shaft that bound the circular knife and the nubber By using the fitting means, the circular knife can be detached from the fixed shaft of the side trimmer while maintaining the vertical and horizontal angles of the circular knife, thereby ensuring the quality after cutting the both ends of the strip and at the same time removing the circular knife.
