Problems solved by technology

[0002] Glass fiber is an inorganic non-metallic material with excellent performance. There are many kinds. Its advantages are good insulation, strong heat resistance, good corrosion resistance and high mechanical strength. When weaving glass fiber cloth on the cloth machine, a sizing device is required, and secondary sizing is required to play a protective role
[0003] The existing glass fiber secondary sizing device has certain disadvantages in use. First, the existing sizing device cannot adjust the position between the sizing rollers, so that the permeability of the size into the glass fiber cloth cannot be controlled. , if the pressure is too high, it will cause damage to the glass fiber. At the same time, the sizing process needs to be sprayed and sizing, which will cause the temperature of the slurry in the spray nozzle to be inconsistent with the temperature in the storage tank, thereby affecting the quality of sizing and prone to uneven sizing. Finally, The existing secondary sizing requires additional sizing rollers and additional control devices, which increases the cost and is inconvenient to use

Embodiment 1

[0031] Such as Figure 1-7 As shown, a glass fiber secondary sizing device includes a storage tank 1, a first circulating pipe 2, a second circulating pipe 8 and a sizing roller structure. The first circulating pipe 2 and the second circulating pipe 8 are respectively connected and installed For the first slurry pump 15 and the second slurry pump 9, one end of the first circulation pipe 2 extends to a position above the storage tank 1 is connected with a spray pipe 3, and the other end of the first circulation pipe 2 is connected to the storage tank 1. Inner conduction, one end of the second circulation pipe 8 extends into the storage tank 1, and the other end of the second circulation pipe 8 is in communication with the storage tank 1, the sizing roller structure is installed in the storage tank 1, and the storage A cylinder 7 is installed on one side of the sump 1. The sizing roller structure includes a first sizing roller 4 and a second sizing roller 5. Both ends of the firs...

Embodiment 2

[0035] Such as figure 2 As shown, the bottom end of the spray pipe 3 is spirally installed with a number of spray nozzles 19, and the spray nozzles 19 correspond to the positions between the first sizing roller 4 and the second sizing roller 5. The surface of the spray pipe 3 is wound with an electromagnetic heating coil. 18, and each tube of the electromagnetic heating coil 18 is located between the spray nozzles 19, and a control unit 20 is installed on one side of the electromagnetic heating coil 18;

[0036] Such as figure 1 with 7 As shown, a first temperature detector 16 is installed on the inner wall of the storage tank 1, a second temperature detector 17 is installed on the inner wall of the intersection of the spray pipe 3 and the first circulation pipe 2, and the first temperature detector 16 and the second temperature detector The devices 17 are electrically connected to the control unit 20;

[0037] Through the electromagnetic heating ring 18, the first temperature sen...

Embodiment 3

[0039] Such as figure 1 with 4 As shown, the second circulation pipe 8 extends to the top of the pipe body in the storage tank 1 with a T-shaped pipe 11, and the top of the T-shaped pipe 11 is provided with a number of through holes, and is located directly below the first circulation pipe 2. Corresponding to ensure the uniformity of the secondary sizing;

[0040] Such as figure 1 As shown, the second circulation pipe 8 extends to the end of the inner tube of the storage tank 1 with a discharge pipe spirally installed, and the pipe diameter of the discharge pipe is one third of the diameter of the T-shaped pipe 11. The slurry pressure in the tube is greater than that in the T-shaped tube 11, but the flow rate is not as much as that in the T-shaped tube 11, which ensures that more slurry is discharged from the T-shaped tube 11 and at the same time generates a certain spray pressure through the through hole;

[0041] Such as figure 1 with 5 As shown, the first circulating pipe 2 and ...

Abstract

The invention discloses a glass fiber secondary sizing device. The glass fiber secondary sizing device comprises a material storage pool, a first circulating pipe, a second circulating pipe and a sizing roller structure. The first circulating pipe and the second circulating pipe are internally connected and provided with a first slurry pump and a second slurry pump. A position, extended to an upper part of the material storage pool, of one end of the first circulating pipe is connected with a spraying pipe, and the other end of the first circulating pipe is communicated with the interior of the material storage pool. The glass fiber secondary sizing device is capable of, through installing the second circulating pipe, pumping out slurry and importing through the second slurry pump, and entering the material storage pool through a pipe body at the other end, achieving the stirring effect, avoiding uneven temperatures in the material storage pool so as to cause a surface film forming phenomenon, at the same time, upwards spraying the slurry through a T-shaped pipe, enabling the slurry to contact with glass fibers on a bottom surface of a first sizing roller in a stamping mode, realizing a new route of secondary sizing, and avoiding using more sizing rollers, simple and practical.

Technical field [0001] The present invention relates to the field of glass fiber, in particular to a glass fiber secondary sizing device. Background technique [0002] Glass fiber is a kind of inorganic non-metallic material with excellent performance. It has a wide variety of advantages. The advantages are good insulation, strong heat resistance, good corrosion resistance, and high mechanical strength. However, the disadvantages are brittleness and poor wear resistance. When weaving glass fiber cloth on the cloth machine, a sizing device is needed and a second sizing is required to protect it. [0003] The existing glass fiber secondary sizing device has certain drawbacks when used. First, the existing sizing device, the position between the sizing rollers cannot be adjusted, so that the penetration rate of the slurry into the glass fiber cloth cannot be controlled. If the pressure is too high, it will damage the glass fiber. At the same time, the sizing process requires spraying...
