Description

Technical Field

[0001] The utility model relates to the technical field of glass fiber production equipment, in particular to a drying device for glass fiber production. Background Art

[0002] Glass fiber woven fabric is a plain fabric with untwisted roving, and is an important base material for hand-laid FRP. The strength of woven fabric is mainly in the warp and weft directions of the fabric. For occasions requiring high strength in the warp or weft directions, it can also be woven into unidirectional fabric, which can arrange more untwisted roving in the warp or weft directions, single warp fabric, single weft fabric, and glass fiber cloth needs to be properly surface treated during production, that is, a surface treatment agent (generally a wetting agent, which includes adhesives, lubricants, emulsifiers and other ingredients) is coated on the surface of the glass fiber. During surface treatment, the glass fiber cloth is first sized in an impregnation tank containing the wetting agent, and then conveyed to the dryer through the cloth guide roller for drying and film formation. The existing drying equipment generally adopts a crawler dryer, that is, the crawler carries the glass fiber cloth forward, and uses the hot air to dry it, which accelerates the formation of its surface protective film, which not only helps to enhance the strength of the fabric, but also improves the wear resistance and waterproof properties of the fabric.

[0003] In addition to drying the glass fiber cloth to form a film, the existing dryer is also used to clean the glass fiber cloth. Since the existing drying equipment can only dry the glass fiber cloth alone, for the cleaned glass fiber cloth roll, the large amount of water adhering to its surface will increase the drying time. Since most glass fiber cloths are rolled up in a roll, it is not convenient to perform automatic water squeezing. If it only relies on single drying, the efficiency is relatively low. In view of this, we propose a drying device for glass fiber production. Utility Model Content

[0023] Furthermore, the end of the reciprocating screw rod 52 is rotatably connected to the inside of the dryer box 1, and the surface of the reciprocating screw rod 52 is connected to the surface of the fan roller 2 through a pulley and a belt transmission, the surface of the limit slider 53 and the surface of the limit frame 54 are respectively slidably connected to the inside of the dryer box 1, and the surface of the limit frame 54 is fixedly connected to the inside of the dryer box 1. Example

[0024] See also Figure 3-Figure 4 As shown, the auxiliary adsorption and extrusion device 5 also includes a pressure base 57 and a material discharge guide plate 58. The surface of the pressure base 57 is fixedly connected to the inside of the drying machine box 1. The end of the material discharge guide plate 58 is fixedly connected to a material guide base 59. The surface of the material guide base 59 is fixedly connected to one side of the drying machine box 1.

[0025] It is worth noting that the rolling water absorption device 56 includes a sliding shaft 561, one end of the sliding shaft 561 is slidably connected to the inner wall of the limit frame 54, the other end of the sliding shaft 561 is fixedly connected to the connecting plate 562, the interior of the connecting plate 562 is slidably connected to the guide rod 563, the end of the guide rod 563 is fixedly connected to the pressure frame 564, the interior of the pressure frame 564 is rotatably connected to the water-absorbing cotton roller 565, a spring is connected between the surface of the pressure frame 564 and the surface of the connecting plate 562, the surface of the sliding shaft 561 is slidably connected to the inner wall of the guide frame 55, and by setting the rolling water absorption device 56, the effect of elastic rolling water absorption on both sides of the glass fiber cloth body is achieved, and the water absorption work of glass fiber cloth bodies of different thicknesses is further achieved.
