Description

Technical Field

[0001] This utility model relates to the field of glass fiber manufacturing, specifically a glass fiber breakage protection and shielding device. Background Technology

[0002] During the glass fiber drawing process, the vertical and horizontal distance between the stencil and the center of the drawing machine's winding equipment is relatively small, causing the stencil and the wire cake being wound by the drawing machine to partially overlap vertically. When impurities or abnormal breaks occur in the molten glass as it passes through the stencil, the broken glass fibers will fall directly onto the wire cake being wound by the drawing machine, resulting in a potential quality hazard of broken glass fibers being embedded in the wire cake. Summary of the Invention

[0003] This invention provides a glass fiber breakage protection device, which can solve the problem of glass fiber breaks falling into the fiber cake during the existing glass fiber drawing process.

[0004] This utility model discloses a fiberglass breakage protection and shielding device, located below the stencil and above the winding equipment of the fiber drawing machine, and suspended from the process hole of the fiber bundle flowing from the ground platform on the second floor of the fiber drawing machine.

[0008] Preferably, the hooking structure includes a first hooking edge, a second hooking edge parallel to the first hooking edge, and a third hooking edge located between the first hooking edge and the second hooking edge. The third hooking edge is formed by bending the upper end of the first inclined baffle downward, and the included angle α between the third hooking edge and the bottom plate is ≤90° to form a hook that hooks the edge of the process hole. The third hooking edge is parallel to and fits the edge of the process hole.

[0009] Preferably, the baffle also includes a second inclined baffle connected to the lower end of the first inclined baffle. The second inclined baffle is further inclined downward relative to the first inclined baffle.

[0010] Preferably, the length of the drainage chute is greater than the length of the first inclined baffle.

[0011] Preferably, the drainage chute is located on one side of the retaining groove, and the drainage chute has a first side plate and a second side plate.

The connection method is simple and reliable. Its baffle can change the falling direction of the glass fiber breakage falling from the sprue plate, thereby changing its falling position and preventing it from falling into the fiber cake formed by the winding equipment of the drawing machine.

[0022] This utility model provides a fiberglass breakage protection device, located below the stencil and above the winding equipment of the fiber drawing machine, and suspended from the process hole (not shown in the figure) of the fiber bundle flowing from the second-floor floor platform. In this embodiment, the process hole is a rectangular hole opened on a horizontal plane. Figure 1-3 As shown, the glass fiber breakage protection device of this embodiment includes a hanging structure 1, a baffle groove 2, and a drainage chute 3. The glass fiber breakage protection device is hung on the edge of the process hole of the fiber bundle via the hanging structure 1. The bottom plate of the baffle groove 2 is a first inclined baffle 21 that is inclined relative to the horizontal plane to change the direction of the glass fiber breakage falling from the sprue. The side plate 23 of the baffle groove 2 is connected to the hanging structure 1. The drainage chute 3 is located inside the breakage baffle groove 2 and is parallel to the baffle groove 2.

[0023] The glass fiber breakage protection device of this utility model is attached to the existing process hole through the hanging structure 1. The connection method is simple and reliable. Its baffle 2 can change the falling direction of the glass fiber breakage falling from the sprue plate, thereby changing its falling position and preventing it from falling into the fiber cake formed by the glass fiber winding equipment of the drawing machine. At the same time, the drainage chute 3 can change the water droplets from the sprue plate and prevent them from falling on the fiber cake.

[0024] The hanging structure 1 includes a first hanging edge 11, a second hanging edge 12 parallel to the first hanging edge 11, and a third hanging edge 13 located between the first hanging edge 11 and the second hanging edge 12. The three hanging edges are respectively hung on the three edges of the process hole, i.e., the steel plate around the hole's ground. The third hanging edge 13 is formed by bending the upper end of the first inclined baffle 21 downwards, and the included angle α between the third hanging edge 13 and the first inclined baffle 21 is ≤90°, forming a hook that hooks onto the edge of the process hole. The third hanging edge 13 is parallel to and fits snugly against the edge of the process hole, thus forming a stable hanging connection.

[0025] like Figure 1 and 2 As shown, the baffle 2 also includes a second inclined baffle 22 fixedly connected to the lower end of the first inclined baffle 21. The second inclined baffle 22 is further inclined downward relative to the first inclined baffle 21. The angle between the first inclined baffle 21 and the horizontal plane is β, and the inclination angle of the second inclined baffle 22 relative to the horizontal plane is γ, where β+20°≥γ≥β+10°. The second baffle can prevent the broken ends of the glass fiber from changing direction and drifting to the area below the coverage of the first inclined baffle 21 when falling from the end of the first inclined baffle 21.

[0026] The length of the drainage chute 3 is greater than the length of the first inclined baffle 21. The drainage chute 3 is located on one side within the baffle 2.

[0027] In this embodiment, the first inclined baffle 21, the second inclined baffle 22, the side plate 23, the first hooking edge 11 and the second hooking edge 12 of the hooking structure 1 of the baffle 2 are formed by bending a first sheet material. The bottom plate 31, the first side plate 32, the second side plate 33 and the second hooking edge 12 of the hooking structure 1 of the drainage inclined trough 3 are formed by bending a second sheet material. The lower surface of the bottom plate 31 of the drainage inclined trough 3 is fixed to the upper surface of the bottom plate of the baffle 2. The first and second sheet materials can be made of stainless steel, and the lower surface of the bottom plate 31 of the drainage inclined trough 3 and the upper surface of the bottom plate of the baffle 2 can be welded together.

[0028] In another embodiment (not shown in the figure), the baffle has two parallel side plates. The first inclined baffle, the second inclined baffle, the two side plates, the first hooking edge and the second hooking edge of the hooking structure of the baffle are formed by bending a first plate. The bottom plate, the first side plate, the second side plate and the second hooking edge of the hooking structure of the drainage trough are formed by bending a second plate. The outer wall surface of the first side plate of the drainage trough is fixed together with the outer wall surface of one side plate of the baffle.

[0029] In addition, the fiberglass breakage protection shielding device can also be equipped with a collection device (not shown in the figure). The collection device is located below the lower end of the drainage chute 3 and the second inclined baffle to collect the water drained from the drainage chute 3 and the fiberglass breaks that fall from the baffle 2.
