The guide bar driving device 2 of the ratchet knitting machine according to the embodiment of the present invention illustrated in FIGS. 1 to 2 is provided with a lever shaft rod 16 and a driving shaft rod 18 on the shaft portion 8, and the shaft portion 8. The drive shaft rod 18 is connected to the shaft of the drive motor 10 installed on one side of the belt 20. Then, the eccentric rotating body 12 having the double eccentric cam 26 is axially mounted on the drive shaft bar 18, and the actuating lever 14 axially mounted on the lever shaft bar 16 is the arm portion of the eccentric rotating body 12. Link is connected to the 22, the operation lever 14 is configured by linking the operating rod (6) connected to the guide bar (4).

As shown in FIGS. 3 to 7, the arm portion 22 is formed on one side of the cam body portion 24 in which the double eccentric cam 26 is embedded, as shown in FIGS. 3 to 7. It is connected and configured. In the exemplary embodiment of the present invention, the double eccentric cam 26 may be formed in a circular shape, and the cam main body portion 24 accommodating the double eccentric cam 26 may also be formed in a circular shape.

An installation hole 38 is formed in the cam body 24 of the eccentric rotating body 12 so as to install the double eccentric cam 26. And, the arm portion 22 of the eccentric rotating body 12 is configured by one side is connected to the cam body portion 24 and the other side is linked to the operation lever (14).

The double eccentric cam 26 inherent in the cam body 24 has a bolt on the outer circumferential surface of the inner cam 26a and the inner cam 26a which are first eccentrically coupled to the drive shaft rod 18 by the bolt 56. (58) The outer cam 26b is coupled to the second eccentric shaft by tightening.

An inner cam 26a of the double eccentric cam 26 is formed with an eccentric shaft hole 47 into which the drive shaft rod 18 is fitted. The drive shaft rod 18 is first eccentric shaft coupled to the eccentric shaft hole 47 of the inner cam 26a by fastening the bolt 56. In addition, an eccentric shaft hole 49 is formed in the outer cam 26b of the double eccentric cam 26, and the inner cam 26a is fastened to the bolt 58 in the eccentric shaft hole 49 so as to be coupled to the second eccentric shaft. In this case, the eccentric shaft hole 47 of the inner cam 26a is formed larger than the diameter of the drive shaft rod 18, and the eccentric shaft hole 49 of the outer cam 26b is formed larger than the diameter of the inner cam 26a. The tightening or loosening of the bolts 56 and 58 makes it possible to adjust the position of the first and second eccentric shafts.

The user can freely adjust the left and right reciprocating motion width of the guide bar 4 by adjusting the lengths of the bolts 56 and 58 to adjust the positions of the first and second eccentric shafts. That is, the farther the position of the drive shaft rod 18 and the center of the double eccentric cam 26 in the double eccentric cam 26 is, the larger the lateral reciprocating movement width of the guide bar 4 is, The net width becomes larger.

In addition, since the center of gravity of the dual eccentric cam 26 is not balanced due to the eccentric shaft, it may be difficult to operate, so that the inner and outer cams 34 and 36 have a plurality of balance adjusting incisions 46 formed on opposite sides of the eccentric shaft. do.

As described above, the double eccentric cam 26 composed of the inner and outer cams 48 and 50 is fitted into the installation hole 38 of the cam body part 24. In this case, an installation groove 44 is formed in the outer circumferential surface of the inner and outer cams 48 and 50, and a snap ring 42 is fitted into the installation groove 44 to be fitted into the installation hole 38 of the cam body part 24. Lose. Then, the bearing 40 is coupled between the installation hole 38 of the cam body portion 24 and the double eccentric cam 26 so that the cam body portion 24 rotates smoothly together with the double eccentric cam 26. do.

On the other hand, the actuating lever 14, which is linked to the arm portion 22 of the eccentric rotor 12, is axially installed on the lever shaft rod 16 of the shaft portion 8, as shown in Figs. . One side of the operation lever 14 is linked to the arm portion 22 of the eccentric rotating body 12, the other side is linked to the operation rod 6 is connected to the guide bar (4). In this case, at one side of the operating lever 14, the link coupling holes 32 to which the arm portion 22 of the eccentric rotating body 12 is connected are formed at regular intervals in the longitudinal direction. In addition, the other side of the operating lever 14, the installation hole 30 to which the operating rod 6 is linked is formed long in the longitudinal direction.

The operating rod 6 installed in the installation tool 30 of the operating lever 14 is connected to the guide bar 4 by the connecting rod 5. In addition, a tension spring 54 for pulling the actuating rod 6 toward one end is installed between the actuating lever 14 and the connecting table 5.

The guide bar 4 serves to guide the plurality of slopes S to the needle bar (not shown). At the bottom of the guide bar 4, a guide (not shown) for guiding the slopes S to be concentrated to a needle bar (not shown) is mounted.

Now, with reference to Figures 8 to 9 will be described the operation of the guide bar drive device 2 of the ratchet knitting machine according to an embodiment of the present invention.

First, the user roughly guides by using the connection distance with the arm portion 22 of the one eccentric rotating body 12 and the connection distance with the other operation lever 14 about the lever shaft 28 of the operation lever 14. Adjust the left and right movement width of the bar (4). That is, by using the link coupling holes 32 and the other side mounting hole 30 of the operating lever 14, the connection position of the arm 22 and the operating lever 14 of the eccentric rotating body 12 is freely available. Adjust to. The larger the width of the left and right movements of the guide bar 4, the wider the width of the net, and the narrower the width of the meshes of the guide bar 4, the narrower the width of the net.

As described above, after adjusting the connecting distance of the operation lever 14 to roughly adjust the width of the net, and in order to precisely adjust the width of the net, the bolts 56 and 58 in the eccentric rotating body 12 are Loosen or tighten the first eccentric shaft position of the drive shaft rod 18 in the eccentric shaft hole 47 of the inner cam 26a and the second eccentric shaft position of the inner cam 26a in the eccentric shaft hole 49 of the outer cam 26b. Adjust it.

 In order to form a wider network, as shown in FIG. 8, the distance between the position of the drive shaft bar 18 and the center of the eccentric rotating body 12 is increased to increase the lateral reciprocating movement width of the guide bar 4. When the width of the network is to be narrowed, the distance between the position of the drive shaft bar 18 and the center of the eccentric rotating body 12 is narrowed as shown in FIG. 9 to narrow the left and right movement width of the guide bar 4.

With the above configuration, the guide bar driving device 2 of the ratchet knitting machine according to the embodiment of the present invention can obtain a knitted fabric in which various mesh widths are formed very simply without replacing parts.

In addition, the left and right reciprocating motion of the operating rod 6 can be made at a high speed by the rhythmic cam operation based on the structure of the double eccentric cam 26 specified in accordance with the present invention to maximize the knitting production of the Raschel knitting machine. In addition, there is little operation noise, and there is less concern about wear of the parts or impact damage.
