The present invention relates to a device for changing the spacing between front and rear trick plates of a double raschel machine and between ground-yarn guide bars.

Conventionally, in a double-shell machine having two rows of front and rear knitting needles, when changing the thickness of the raw dough to be knitted, it is necessary to change the spacing of the front and rear partial knitting needles facing each other. It is necessary to change the spacing of the front and rear trick plates.

Specifically, in order to change the said gap, it is necessary to loosen the adjustment rod connected indirectly to the trick plate, adjust its length, fine-tune the trick plate using a dial gauge, and tighten each adjustment rod. There was. Moreover, it was also necessary to perform the front-back adjustment of the flooring chamber body by expanding or narrowing the space | interval of a front-back part trick plate.

As an apparatus for changing and adjusting the distance between the front and rear trick plates, the present applicant has proposed and filed the devices of Japanese Patent Application Laid-Open Nos. 2000-80545 and 2003-201655.

The apparatus of Japanese Unexamined Patent Application Publication No. 2000-80545 connects an eccentric mechanism having a locking means to one end of each connecting rod connected to each support lever supporting the opposite and opposite trick plates before and after each other, and at the time of changing the trick plate spacing. The support lever is rotated by releasing the locking means and turning the handle attached to the eccentric mechanism to displace the connecting rod to change the distance between the front and rear trick plates supported at the tip.

However, the proposed device is not only applicable to the machine of the type where the trick plate swings because the change adjustment operation is considerably complicated and cumbersome, and the trick plate is displaced by turning about the axis of the support lever.

In addition, in the case of the apparatus of JP-A-2003-201655, the rotation of the screw shafts in which the front and rear part intermediate frames supporting the front and rear partial needle plates and the front and rear part trick plates are installed in the front and rear direction, and the rear and rear mechanical brackets are installed in the front and rear directions. By moving in a straight line, the distance between the trick plates is adjusted. To this end, a large driving force is required for the movement of both front and rear machine stands, and the cam unit on the main shaft that becomes the driving source of the knitting machine as well as the device for the movement is enlarged, in the case of the model of the oil bath system. Since it is not possible to move the main shaft containing the wealth, it cannot be used as it is, and the cost has increased considerably.

The present invention has been made in view of the above points, and it is possible to easily change the distance between the front and rear trick plates of the double shell machine and the body for the bottom chamber with a simple operation, and the cam portion of the drive source on the main shaft is an oil bath type, An object of the present invention is to provide a gap changing device between a trick plate and a body for a floor chamber that can be used in any model of the open type.

The present invention to solve the above problems is the front and rear middle frame, the front and rear middle frame, the front and rear middle frame for holding the front and rear partial trick plate, the front and rear partial needle heat and the trick plate, respectively, in the front and rear two rows of single needle fever and the two partial needle fever, In a double-shell system comprising a bottom chamber body for a rear floor room and a pile body, the front and rear support metals for supporting the front and rear trick plates and moving in a spaced apart or proximate direction with partial needle heat in the spaced apart or proximal directions, respectively. A drive means for moving the support metal and the hanger, respectively; And the support metal and the operation by operation of the respective driving means. By moving the hanger, the space between the front and rear trick plates is configured to be changeable together with the partial needle heat, and the space between the body for the front and rear floor chambers is changeable.

According to the interval changing device, since the trick plate and the bottom chamber body can be moved in a straight line by operating the respective drive means, the interval can be adjusted and adjusted, so that the change can be easily performed. In addition, since a large capacity driving force is not required, it is possible to easily cope with a long single width.

In the above gap changing device, it is preferable to configure the gap between the front and rear trick plates and the gap between the front and rear floor chambers so that they can be changed at the same time. Can be greatly reduced.

In addition, it is preferable that the driving means is made of an eccentric mechanism provided on the driving shaft for movement, respectively, for the movement of the support metal of the trick plate and the hanger of the body for the bottom chamber. It is possible to move the support metal with a small device and to perform it at low cost.

Further, if the drive means for moving the support metal of the trick plate and the hanger of the body for the floor chamber is configured to interlock by rotation transmission means including a timing belt, Change adjustment can be performed simultaneously with one driving force.
