[0002] The heart component of big disc knitting machine is the key part of the whole machine to realize knitting function, and the middle and upper disc cutting block is an important component of the heart of the knitting machine.The traditional connection mode of the middle and upper disc cutting block is pin type positioning, and the positioning mode is to position from top to bottom by two pins, which requires high accuracy of the pin, and customers often report that there is a deviation during use, which causes horizontal and vertical stripes and shadow stripes on the cloth surface, so it is necessary to improve the structure. SUMMARY

[0003] The utility model discloses a heart of big disc knitting machine.

[0004] The utility model discloses a heart of big disc knitting machine.

[0005] A heart of big disc knitting machine includes a middle and an upper disc cutting block, and the middle edge is provided with an annular mounting step.

[0006] The bottom of the upper disc cutting block is provided with a pin groove, and the annular mounting step is provided with a positioning pin for limiting and fixing the pin groove.

[0007] The circular end surface of the upper disc cutting block is attached to the circular end surface of the middle.

[0008] The upper disc cutting block and the middle are fixed by inclined screws.

[0009] In the utility model, the two circular end surfaces of the upper disc cutting block and the middle are attached and positioned in the front and rear directions of the upper disc cutting block, the positioning pin is used to position the left and right directions of the upper disc cutting block, and the inclined screws are used to lock the two circular end surfaces of the upper disc cutting block and the middle and the annular mounting step, so as to reduce the left and right deviation of the upper disc cutting block during use, improve the cloth surface effect and production efficiency.

[0010] The included angle between the inclined screw and the annular mounting step is 60°. The included angle of 60° is the best angle, so that the two circular end surfaces of the upper disc cutting block and the middle can be tightly attached.

[0011] The connection between the upper disc cutting block and the middle is provided with an annular clearance groove and a hemispherical clearance groove. The annular clearance groove is located at the bottom of the upper disc cutting block, and the hemispherical clearance groove is located on the annular mounting step. By designing the annular clearance groove and the hemispherical clearance groove, the connection between the upper disc cutting block, the annular mounting step and the inclined screw has a certain space, which reduces the connection obstruction caused by the inclined screw, ensures the stability of the connection, and facilitates the smooth entry of the inclined screw into the connection.

[0012] The diameter of the oblique screw is half of the diameter of the semispherical clearance groove.

[0013] The annular mounting step side wall and the upper disc cutting block are provided with a gap clearance groove. If the annular mounting step side wall and the upper disc cutting block are in contact connection, the precision requirement for the fit of the two is higher, it is not easy to achieve, and it is also easy to interfere with the circular end positioning surface of the middle core and the upper disc cutting block or the planar positioning surface of the annular mounting step and the upper disc cutting block. The utility model avoids the contact of the annular mounting step side wall and the upper disc cutting block and avoids the interference with the circular end positioning surface of the middle core and the upper disc cutting block or the planar positioning surface of the annular mounting step and the upper disc cutting block by designing the gap clearance groove.

[0014] The utility model has the advantages that:

[0015] The upper disc cutting block and the middle core are positioned in the front and back directions through the fit of the two circular end surfaces, the left and right directions of the upper disc cutting block are positioned through the positioning pin, and the upper disc cutting block and the middle core are tightly fitted through the locking of the oblique screw, so that the left and right swing of the upper disc cutting block in the use process is reduced, and the cloth surface effect and production efficiency are improved.
