Description

Technical Field

[0001] This utility model relates to the field of warp knitting machine technology, specifically a high-strength crankshaft for a high-speed Tricojaka warp knitting machine. Background Technology

[0002] The main loop-forming components of a warp knitting machine include knitting needles, guide needles, sinkers, and pressure plates (for crochet machines). The knitting needles are mounted in rows on the needle bed and move with it. The guide needles are mounted on slats to form guide bars. The warp yarns pass through the eyelets of the guide needles and, moving with the guide bars, wrap around the needles. Through the coordinated movement of the knitting needles, sinkers, and other loop-forming components, the fabric is woven. Currently, warp knitting machines typically use a crankshaft and connecting rod drive.

[0003] The published patent document CN202610497U discloses a crankshaft, particularly a warp knitting machine crankshaft, comprising a first crankshaft, a second crankshaft, a first end shaft, and a second end shaft. The first crankshaft and the first end shaft are fixedly connected by a first screw, and the second crankshaft and the second end shaft are fixedly connected by a second screw. The first and second end shafts are fixedly connected to a coupling by a third screw. The keyways on the first and second end shafts correspond to each other, and flat keys for fixing the positions of the first and second end shafts are provided in the keyways. The warp knitting machine crankshaft is simple and convenient to install, has high precision and good reliability, facilitates crankshaft replacement, and effectively avoids the processing difficulties caused by full-width crankshafts.

[0004] The first and second end shafts of the above patent abut each other, and the two end shafts are connected only by screws and couplings. When subjected to torque, the end shafts will rotate, affecting normal use. Therefore, a high-strength crankshaft for a high-speed Tricojaka warp knitting machine is needed. Utility Model Content

[0005] The purpose of this invention is to provide a high-strength crankshaft for a high-speed Tricojaka warp knitting machine, which solves the problems mentioned in the background art.

[0006] This application provides a high-strength crankshaft for a high-speed tricojaka warp knitting machine, comprising a first crankshaft, a first end shaft mounted on one outer wall of the first crankshaft, a first bolt threaded through the first end shaft and threadedly connected to the first crankshaft, a slot formed on the shaft end face of the first end shaft, a limiting block fixedly connected to the inner wall of the slot, a second crankshaft disposed on the side of the first end shaft away from the first crankshaft, a second end shaft mounted on the side of the second crankshaft facing the first end shaft, a second bolt threaded through the second end shaft and threadedly connected to the second crankshaft, an insert rod fixedly connected to the shaft end face of the second end shaft, the insert rod being inserted into the interior of the slot, a limiting groove formed on the outer wall of the insert rod, and the limiting block engaging with the limiting groove.

[0007] In use, the first and second end shafts are first installed by abutting each other. The insert rod on the second end shaft can be inserted into the slot on the first end shaft. When the insert rod is inserted into the slot, the limiting block in the slot engages with the limiting groove on the insert rod. Through the cooperation of the above structures, the rotation of the first and second end shafts can be avoided when they are subjected to torque. Then, the first and second end shafts are further fixed by couplings and screws to complete the installation. In addition, both the first and second crankshafts are made of medium carbon alloy steel, which improves the strength of the shaft.

[0008] Optionally, a coupling is fitted onto the outside of the connection position between the first end shaft and the second end shaft.

[0009] By adopting the above technical solution, it is beneficial to flexibly install and disassemble the first and second end shafts.

[0010] Optionally, the coupling consists of two semi-circular plates with their openings facing each other, and the two semi-circular plates are fixedly connected by screws.

[0011] By adopting the above technical solution, it is beneficial to improve the firmness of the connection between the first end shaft and the second end shaft.

[0012] Optionally, the inner wall of the coupling is provided with anti-slip texture.

[0013] By adopting the above technical solution, it is beneficial to improve the friction between the shafts of the first and second end shafts and the coupling.

[0014] Optionally, the diameter of the insertion rod is adapted to the aperture of the slot.

[0015] By adopting the above technical solution, the gaps generated when the insertion rod is inserted into the slot can be reduced, and the shaking of the insertion rod can be avoided.

[0016] Optionally, four limiting blocks are provided, and the four limiting blocks are distributed in a ring shape.

[0017] By adopting the above technical solution, the limiting effect is further improved.

[0018] Optionally, the insertion rod and the second end shaft are an integral structure.

[0019] By adopting the above technical solution, the connection between the insertion rod and the second end shaft can be strengthened, thus avoiding breakage.

[0020] Compared with the prior art, the beneficial effects of the technical solution of this application are as follows:

[0021] When the first and second end shafts of this application's technical solution abut against each other, the insertion rod on the second end shaft can be inserted into the slot on the first end shaft. When the insertion rod is inserted into the slot, the limiting block in the slot engages with the limiting groove on the insertion rod. Through the cooperation of the above structures, the rotation phenomenon can be avoided when the first and second end shafts are subjected to torque, so as not to affect normal use.
