Since the purpose of changing the needle running trajectory process is achieved by manually disassembling and replacing the triangle, this operation method is time-consuming and labor-intensive. Summary of the invention

[0003] In view of the above-mentioned prior art, the technical problem to be solved by the utility model is to provide a needle running track changing device used in a single-sided circular knitting machine, which can automatically switch between a flat needle track and a thrust needle track according to the requirements of the knitting process.

[0004] In order to solve the above technical problems, the knitting needle running track changing device of the utility model includes a triangle body and a saddle, the triangle body is drilled with a fixing hole, the triangle body is installed on the upper end of the working surface of the saddle by screws, the saddle is drilled with a transverse rod hole, the transverse rod hole runs from the back of the saddle to the working surface of the saddle, the working surface of the triangle body is milled with a concave track groove, the bottom edge of the track groove is a straight track, the top edge of the track groove is a zigzag track, and the middle part of the triangle body is milled with a hollow hole, and a flat needle or needle lifting track switching mechanism is installed at the hollow hole. Since the flat needle or needle lifting track switching mechanism can realize the purpose of automatically switching the flat needle running track and the needle lifting running track, it solves the time-consuming and laborious problems of manually disassembling and replacing the triangle to change the knitting needle track process, thereby improving the working efficiency of the single-sided circular knitting machine.

[0005] Furthermore, the hollow hole is communicated with the rail groove.

[0006] As a further improvement of the utility model, the flat needle or push needle trajectory switching mechanism includes a movable track changing block and a cylinder. The movable track changing block is drilled with screw holes. The cylinder is fastened to the back of the saddle by screws. The piston rod of the cylinder passes through the transverse rod hole from the back of the saddle and then passes through the working surface of the saddle and is fastened to the movable track changing block by screws. The cylinder can control the movable track changing block to move forward or backward through the piston rod.

At this time, the triangular body is in the flat needle track state. At this time, the bottom edge of the straight track of the track groove serves as the guide track for the knitting needle to run, thereby performing the flat needle operation process of the knitting needle. When the cylinder controls the movable track-changing block to complete the forward movement through the piston rod, the movable track-changing block enters the track groove. At this time, the triangular body is in the needle-lifting track state. In this case, the bottom edge of the movable track-changing block overlaps with the middle section of the bottom edge of the track groove. At the same time, the front section of the bottom edge of the track groove, the top edge of the movable track-changing block, and the end section of the bottom edge of the track groove are combined to form a track curve. The track curve is the same as the top edge track of the track groove, thereby forming a guide track for guiding the knitting needle to perform the needle-lifting operation process.

[0014] Figure 1 , Figure 2 , Figure 3 The utility model shows that the knitting needle running track changing device includes a triangular body A and a saddle B. The triangular body A is drilled with a fixing hole A1. The triangular body A is installed on the upper end of the working surface of the saddle B by screws. The saddle B is drilled with a transverse rod hole. The transverse rod hole passes from the back of the saddle B to the working surface of the saddle B. A recessed track groove A2 is milled on the working surface of the triangular body A. The bottom edge of the track groove A2 is a straight track, and the top edge of the track groove A2 is a zigzag track.

[0015] In order to realize the purpose of automatic switching between the flat needle running track and the jacking needle running track, a hollow hole A3 is milled in the middle of the cam body A, and a flat needle or jacking needle track switching mechanism is installed at the hollow hole A3.

[0016] Furthermore, the hollow hole A3 is connected to the track groove A2. Since the saddle B is installed on the saddle bottom ring in the outer diameter direction of the lower needle cylinder of the single-sided circular knitting machine, the side of the saddle B facing the lower needle cylinder is used as the working surface, and the other side opposite to the working surface is used as the back surface. The back surface of the saddle B is located in the outer diameter direction of the working surface of the saddle B. Since the triangular body A is installed on the upper end of the working surface of the saddle B by screws, the side of the triangular body A facing the lower needle cylinder is also used as the working surface, and the back surface of the triangular body A contacts the working surface of the saddle B. The hollow hole passes through from the back surface of the triangular body A to the track groove A2.

[0017] As a further improvement of the utility model, Figure 1 , Figure 2 As shown, the flat needle or push needle trajectory switching mechanism includes a movable track changing block C1 and a cylinder C2. The movable track changing block C1 is drilled with a screw hole C11. The cylinder C2 is fastened to the back of the saddle B by screws. The piston rod of the cylinder C2 passes through the transverse rod hole from the back of the saddle B and then passes through the working surface of the saddle B and is fastened to the movable track changing block C1 by screws. The cylinder C2 can control the movable track changing block C1 to move forward or backward through the piston rod.

[0018] Furthermore, the bottom edge of the movable track-changing block C1 is a straight line, and the top edge of the movable track-changing block C1 is a curve.

[0019] The shape of the hollow hole A3 is not limited, the diameter of the hollow hole A3 is larger than the length of the movable track change block C1, and the movable track change block C1 can be completely embedded in the hollow hole A3. The shape of the hollow hole A3 can also be the same as the outer edge of the movable track change block C1.

[0020] The cylinder C2 is controlled by PLC. Figure 2 As shown, when the cylinder C2 controls the movable track-changing block C1 through the piston rod to complete the retraction action, the movable track-changing block C1 can be retracted into the hollow hole A3. At this time, the triangular body A is in a flat needle track state. At this time, the bottom edge of the track groove A2 is a linear track as a guide track for the knitting needle to run the flat needle operation process. Figure 1 As shown, when the cylinder C2 controls the movable track-changing block C1 through the piston rod to complete the forward movement, the movable track-changing block C1 enters the track groove A2. At this time, the triangle body A is in the needle-lifting track state. In this case, as shown in FIG. Figure 3 As shown, the bottom edge of the movable track-changing block C1 overlaps with the middle section of the bottom edge of the track groove A2. At the same time, the front section of the bottom edge of the track groove A2, the top edge of the movable track-changing block C1, and the end section of the bottom edge of the track groove A2 are combined to form a trajectory curve. The trajectory curve is the same as the top edge trajectory of the track groove A2, thereby forming a guide trajectory for guiding the knitting needles to perform the needle lifting operation process.

[0021] Since the flat needle or jack needle track switching mechanism can realize the purpose of automatic switching between the flat needle running track and the jack needle running track, the utility model not only saves time and labor in operation, but also improves the working efficiency of the single-sided circular knitting machine.
