Example Embodiment

[0026] Example 1

[0027] A device for adjusting the water content of long glass fibers includes a water tank 1 and a heater 3. The long glass fibers 8 pass through the through holes 4 on both sides of the water tank 1, and the heater 3 generates water vapor inside the tank 1 after heating. The glass fiber 8 changes its own water content in a water vapor environment. The air humidity in the box 1 is measured by a hygrometer 2. The water content of the long glass fiber 8 can be changed by changing the humidity in the special water tank 1. In the box 1, The air humidity can be achieved by adjusting the frequency converter 3a in the heater 3 to change the heating power. When the water in the tank 1 is not enough, you can open the valve on the water inlet 6 to supplement the normal temperature water. Because the water evaporates slowly, change The water frequency is very low, so it can be done by manually adjusting the valve.

Example Embodiment

[0028] Example 2

[0029] When the air humidity in the box 1 is not suitable, you can also change the amount of water vapor generated by changing the flow of the water inlet 6 and the drain 5 to change the air humidity in the box 1, and change the content of the long glass fiber 8. Water volume.

Example Embodiment

[0030] Example 3

[0031] When the speed of the long glass fiber 8 passing through the box body 1 is changed, the purpose of changing the air humidity in the box body 1 as in Embodiment 1 or Embodiment 2 can also be achieved, so that the water content of the long glass fiber 8 meets the production requirements. If in some cases, the speed of the glass fiber 8 passing through the box 1 is not matched with the speed of producing modified plastic particles, it is not suitable.

Abstract

The invention relates to an auxiliary service for processing plastic particles in a plastic modifying trade, particularly to a device for adding glass fibers in plastic particle processing and humidifying the glass fibers. A through hole (4) is respectively punched on two corresponding lateral plates along the length direction in a box body (1) of a glass fiber humidity conditioning device, a heater (3) is arranged at the bottom of the box body (1), a water tank (7) is arranged at the lower part of the box body (1), and a hygrometer (2) is inserted in the box body (1). The glass fiber humidity conditioning device has simple structure and convenient use and maintenance, and the moisture of long glass fibers is conveniently and effectively adjusted through the steam generated by water heated by the heater, thereby ensuring the production and the product quality of modified plastic particles.

Description

(1) Technical field [0001] The invention relates to an auxiliary device for processing plastic particles in the plastic modification industry, in particular to a device for adding glass fibers to the processing of plastic particles and increasing humidity to the glass fibers. (2) Background technology [0002] Reinforcement modification is one of the most commonly used modification methods in the plastic modification industry, and the most commonly used method of reinforcement modification is to add glass fiber reinforced materials. The mechanical properties of plastics modified by glass fiber are doubled, and the processing performance is improved. On the contrary, the price of modified products will decrease. [0003] In view of the above advantages of glass fiber, glass fiber is widely used in reinforcement modification, but in the processing of glass fiber and plastic, usually different products require different water content of glass fiber, if the water content of glas...
