Description

Technical Field

[0001] This utility model relates to the field of fiber drawing machine technology, and in particular to a CNC precision yarn blocking mechanism for a glass fiber drawing machine. Background Technology

[0002] A glass fiber drawing machine is a high-speed mechanical device that draws molten glass into fiber filaments and winds them into fiber rolls according to a certain pattern. During the production process, the glass fiber filaments are first wound onto the winding ring at the front end of the impeller mechanism, and then, under the action of the wire-blocking mechanism, gradually wound onto the winding drum on the impeller mechanism to form a roll.

[0003] Chinese utility model patent CN 220812222 U discloses a controllable wire-blocking device for a glass fiber drawing machine. The device includes a support frame, a wire-blocking rod slidably disposed within the support frame along its length, and a rotating wire rod rotatably disposed within the support frame. The rotating wire rod is arranged parallel to the wire-blocking rod. A drive assembly is located at the end of the rotating wire rod away from the wire-blocking plate. A nut slide is helically connected to the rotating wire rod, and the nut slide is fixedly connected to a connecting seat. The drive assembly drives the rotating wire rod to rotate, thereby moving the wire-blocking rod. The support frame includes a first side plate and a second side plate arranged parallel to each other, connected by a connecting plate. A linear bearing is disposed through the first side plate, and the wire-blocking rod passes through the linear bearing, with the wire-blocking plate located at the end of the first side plate outside the first side plate.

[0004] Regarding the aforementioned technologies, the inventors believe the following drawbacks exist: In the above solutions, the yarn-blocking rod slides within the linear bearing under the drive of the drive assembly, and the yarn-blocking task is achieved through the yarn-blocking plate at its front end. However, during the yarn-blocking movement, dirt easily adheres to the yarn-blocking rod, causing friction as it slides within the linear bearing. This leads to wear on the yarn-blocking rod during operation, affecting its lifespan. In severe cases, it can even cause the yarn-blocking rod to become stuck within the linear bearing, hindering work efficiency. Utility Model Content

[0005] To solve the above problems, this utility model provides a CNC precision yarn-blocking mechanism for a glass fiber drawing machine.

One end of the yarn-blocking rod 30 is located inside the guide frame 10 and a guide connecting seat 31 is provided at the end. The other end is located outside the guide frame 10 and a yarn-blocking assembly 40 is provided at the end. A drive assembly 50 is provided inside the guide frame 10 to drive the yarn-blocking rod 30 to slide horizontally. The drive assembly 50 drives the yarn-blocking rod 30 to reciprocate with the yarn-blocking assembly 40.

[0028] Specifically, a support slide 21 is provided on the lower side of the inner wall of the waterproof sleeve 20. The support slide 21 is fixed to the waterproof sleeve 20 and provides sliding support for the yarn-blocking rod 30. A front sealing gasket 22 and a rear sealing gasket 23 are respectively provided at both ends of the support slide 21 inside the waterproof sleeve 20. A front pressure plate 24 and a rear pressure plate 25 are provided on the side of the front sealing gasket 22 and the rear sealing gasket 23 away from the support slide 21. The front pressure plate 24 and the rear pressure plate 25 are used to fix the front sealing gasket 22 and the rear sealing gasket 23, thus forming a sealed cavity inside the waterproof sleeve 20. An oil injection hole 28 communicating with the inner cavity is provided on the upper side of the waterproof sleeve 20. Lubricating oil can be injected into the sealed cavity inside the waterproof sleeve 20 through the oil injection hole 28 to lubricate the yarn-blocking rod 30 and coat the rod body with an oil film, preventing dirt from adhering to the rod body and making the back-and-forth movement of the yarn-blocking rod 30 more flexible.

[0029] Inside the waterproof sleeve 20, a front sealing plate 26 is provided at one end of the waterproof sleeve 20 near the yarn-blocking assembly 40.

The rotary joint 34 is connected to an external water source via a water pipe. A through hole is provided inside the yarn-blocking rod 30 to connect the nozzle 33 to the rotary joint 34, thereby supplying water to the nozzle 33. When the nozzle 33 moves with the yarn-blocking rod 30, the water flow cleans the equipment below. A cleaning brush 43 is also installed at the lower end of the connecting rod 41. The bottom of the cleaning brush 43 is located on the trough mechanism and can clean the trough.

[0034] A drag chain support plate 15 is provided between the first support plate 11 and the second support plate 12. The water pipe can be placed inside the drag chain support plate 15 to avoid the water pipe bending and affecting the equipment rinsing.

[0035] A water collection trough 16 is provided below the yarn-blocking rod 30. The water collection trough 16 is used to prevent oil and other debris from dripping and contaminating the mechanism below, thus protecting the mechanism below.
