Description

Technical Field

[0001] The utility model relates to the technical field of textile machinery, in particular to a textile needle replacement structure for a textile machinery. Background Art

[0002] The replacement structure of textile machinery needles generally includes the following parts:

[0003] 1. Tool holder: The tool holder is the main component that supports the needle on the textile machinery. It is usually made of metal and has a stable shape and rigidity. The design of the tool holder should take into account the convenience and stability of needle replacement.

[0004] 2. Unlocking mechanism: The unlocking mechanism is used to fix and release the needle. It can be manual or automatic. Manual unlocking mechanisms usually use spiral nuts, retaining springs, etc. to fix or release the needle by rotating or moving. Automatic unlocking mechanisms usually use pneumatic or electric methods to fix and release the needle through a control system.

[0005] 3. Fixing mechanism: The fixing mechanism is used to fix the position of the needle on the tool holder. It can be a bolt, pin, etc., which keeps the needle in the correct position by tightening and locking.

[0006] 4. Connection mechanism: The connection mechanism is used to connect the needle and the knife holder. It is usually composed of threaded connection, gear connection, etc., and the needle and the knife holder are tightly connected by tightening or rotating.

[0007] 5. Lubrication system: The lubrication system is used to provide lubricating oil to the needle and the connecting mechanism to reduce wear and friction. The lubrication system usually includes components such as a lubricating oil tank, a lubricating pipe and a lubricating nozzle, as well as a corresponding lubricating oil pump and a control system.

[0008] In the prior art, when replacing the needle of a textile machine, it is usually necessary to first open the unlocking mechanism, fix the mechanism, then tighten or rotate the connecting mechanism, and finally perform lubrication operations, and the operation of the unlocking mechanism usually requires the operator to manually rotate or move to fix or release the needle. This may require additional manpower and time, especially in large machinery, where replacing multiple needles becomes cumbersome and the design of the manual unlocking mechanism is relatively complex, requiring the operator to have certain skills and experience to ensure that the needle is correctly fixed or released, which may lead to operational errors or extended replacement time.
