Description

Technical Field

[0001] The utility model relates to the technical field of circular knitting machines, in particular to a novel adjustable triangle seat. Background Art

[0002] The circular knitting machine is composed of a frame, a yarn supply mechanism, a weaving mechanism, a transmission mechanism, a lubrication and dust removal mechanism, an electrical control mechanism, a pulling and winding mechanism and other auxiliary devices. The weaving mechanism is the core of the circular knitting machine, which mainly includes a needle cylinder, a needle disc, a knitting needle, a triangle seat, a triangle fixed on the triangle seat and other components. The traditional triangle seat is provided with one or more threaded holes, which are threadedly connected to the threaded holes by bolts, thereby fixing the triangle on the triangle seat. However, when the circular knitting machine is weaving different styles of fabrics, the triangle needs to be replaced to adapt to the process steps of weaving the fabrics, and the position of the threaded hole on the triangle seat is fixed, which is difficult to adapt to the installation of the triangle. It is necessary to specially make a triangle that matches its installation, or to connect the triangle seat and replace it together, which makes the use cost expensive.

[0003] The existing triangular seat is provided with a slider and a threaded hole is provided on the slider to adjust the position of the threaded hole. For example, Chinese patent application No. 201310078290.7 discloses a lower triangular adjustment mechanism for a small circular knitting machine. The lower triangular seat is saddle-shaped and is formed with countersunk holes, large holes, small holes, screw holes and T-shaped slots. A slider tapered hole is formed on one side of the T-shaped slider, and a slider countersunk hole is formed on the other side. The adjustment column is formed with a stepped hole and a through hole; the third compression spring is placed in the key-shaped slot of the lower triangular seat, and the T-shaped slider is inserted into the T-shaped slot of the lower triangular seat. The first adjusting screw passes through the first compression spring, the through hole of the adjusting column, and the screw hole on the lower triangular seat, and its conical head is inserted into the third compression spring on the lower triangular seat. The second compression spring is placed in the small hole on the lower triangular seat, and the steel ball is placed on the second compression spring. The adjusting column is placed in the large hole on the lower triangular seat and pressed against the steel ball. The first compression spring is placed in the stepped hole of the adjusting column. The first adjusting screw passes through the first compression spring, the through hole of the adjusting column, and the screw hole on the lower triangular seat, and its conical head is pressed against the conical hole of the slider on the T-shaped slider.

[0004] During installation, the T-shaped slider is embedded into the T-shaped slot from the upper or lower end of the T-shaped slot of the triangular seat, and then threadedly connected to the threaded hole through the first adjusting screw. The inner end of the first adjusting screw abuts against the side of the slider tapered hole of the slider, and is threadedly connected to the slider through the second adjusting screw. The inner end of the second adjusting screw is embedded in the key slot and abutted by the third compression spring, thereby fixing the T-shaped slider.

[0005] However, the following defects were found in actual use:

[0006] 1) The sliding direction of the T-shaped slider in the T-shaped groove is limited by the cooperation of the second adjusting screw and the third compression spring. When the needle cylinder rotates, the knitting needle on the needle cylinder is driven to rotate along the central axis of the needle cylinder. The needle butt on the knitting needle is embedded in the track of the triangle. The knitting needle can move in the needle groove of the needle cylinder along the axial direction of the needle cylinder through the triangle track. In the process of pushing the knitting needle to move, the knitting needle also acts on the triangle with a reaction force, thereby causing the force to act on the slider, and the first adjusting screw abuts against one side of the slider cone hole of the slider, and the third compression spring is elastic, which is easy to cause the reciprocating vibration of the T-shaped slider under the force, resulting in poor quality of the woven fabric;

[0007] 2) The running vibration of the circular knitting machine is transmitted to the T-shaped slider, which can also easily cause the reciprocating vibration of the T-shaped slider, resulting in poor quality of the woven fabric. Utility Model Content

[0008] Therefore, in view of the above problems, the utility model provides a novel adjustable triangle seat, which mainly solves the problem of poor stability of the slider on the adjustable triangle seat in the prior art, resulting in poor weaving quality.

[0009] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0010] 4. The repairing kit for automotive dents, according to claim 1, wherein the two trackbacks are connected along the vertical traverse of the trackback, and the trackback has two opposite ends. The trackbacks are connected along the vertical traverse of the trackback, and the trackback has two end ends. The trackbacks are connected along the vertical traverse of the trackback, and the trackback has two end ends. The trackbacks are connected along the vertical traverse of the trackback.

[0011] Furthermore, a second step portion is recessed at the lower end of the back side of the mounting block, and the first spring is distributed at the second step portion.

[0012] Furthermore, a disk body is fixed to the outer end of the adjusting bolt, and a plurality of first positioning holes are evenly arranged around the bottom surface of the disk body. At least one second positioning hole is arranged on the back side of the base and around the first threaded hole. A second spring and a positioning rod are arranged in each of the second positioning holes, and the outer end of the positioning rod is pressed against the first positioning hole through the second spring.

After the adjustment is completed, when the adjusting bolt is pressed against the inclined surface, it generates a downward cutting force and an outward force, and the outward force pushes the mounting block against the upper fixed block and the lower fixed block, so that the mounting block forms a static friction force with the upper fixed block and the lower fixed block, and a balance is formed by the elastic force of the first spring, the downward cutting force, the force acting on the mounting block during the track movement of the needle butt of the knitting needle along the cam, and the static friction force, thereby limiting the movement of the mounting block, that is, the mounting block forms a fixed state, so that the quality of the woven fabric is guaranteed. The adjustable cam seat has a simple structure and is convenient to install and adjust. BRIEF DESCRIPTION OF THE DRAWINGS
