Problems solved by technology

[0002] Most of the current packing belts are made of iron or ordinary plastic. Iron packing belts need to consume a lot of iron, and are easy to corrode and break, and the edges of the packing belts are sharp, dangerous to operate, easy to hurt hands and damage equipment. Bundle objects
However, the tensile strength of the packing belt made of ordinary plastic is not enough, the elongation and recovery rate are high, the continuous tension is poor, and it is easy to weather in the natural environment.

Embodiment 1

[0021] A packing belt made of continuous fiber reinforced thermoplastic material, wherein the continuous fiber is continuous basalt fiber, and the thermoplastic resin is linear low-density polyethylene. The preparation method includes the following steps: the creel 2 is set on the spindle support 1, the continuous fiber roll 3 is wound on the creel 2, and the continuous fiber bundle 4 is drawn out. The continuous basalt fiber bundle 4 is drawn from the continuous fiber roll 5 on the creel 2 and spread by the tension roller 6, and enters the preheating device 8 through the conveying roller 7. , the left die head 12, the continuous double extrusion die head can be opened and closed and pre-impregnated with molten linear low-density polyethylene, the temperature of pre-impregnation is 250 ℃, and then the first impregnated calender roll 14, the second impregnated calender roll 15. The third impregnated calender roll 16 is impregnated and preliminarily shaped to form a continuous b...

Embodiment 2

[0023] A packing belt made of continuous fiber reinforced thermoplastic material, wherein the continuous fiber is continuous glass fiber, and the thermoplastic resin is polypropylene. Its preparation method includes the following steps: the continuous glass fiber bundle 4 is drawn from the continuous glass fiber roll 5 on the creel 2 and spread by the tension roller 6, and enters the preheating device 8 through the conveying roller 7, and the temperature of the preheating device 8 rises to 220 ℃, and then introduced into the right die head 11, left die head 12, continuous double-extrusion die head and molten thermoplastic resin for pre-impregnation, the temperature of pre-impregnation is 270 °C, and then introduced into the impregnated first impregnated calender roll 14. The second impregnated calender roll 15 and the third impregnated calender roll 16 are impregnated and preliminarily shaped to form an impregnated continuous glass fiber belt 20, impregnated with the first impr...

Embodiment 3

[0025] A packing belt made of continuous fiber reinforced thermoplastic material, wherein the continuous fiber is continuous aramid fiber, and the thermoplastic resin is nylon 6. The preparation method includes the following steps: the continuous aramid fiber bundle 4 is drawn out from the continuous aramid fiber roll 5 on the creel 2 and spread by the tension roller 6, and enters the preheating device 8 through the conveying roller 7, and the temperature of the preheating device 8 is Rise to 240°C, and then introduce the right die head 11, the left die head 12, the continuous double extrusion die head and the molten thermoplastic resin are pre-impregnated, the temperature of the pre-impregnation is 280°C, and then the first impregnation The impregnated calender roll 14, the second impregnated calender roll 15, and the third impregnated calender roll 16 are impregnated and initially shaped to form a continuous aramid fiber strip 20 after impregnation, and the first impregnated ...

Abstract

The invention relates to a packing belt and a manufacturing method thereof. According to the invention, a continuous fiber bundle (4) is led out from a continuous fiber roll (3) on a yarn creel (2), and is unfolded through a tension roller (6); the continuous fiber bundle (4) is delivered into a preheating device (8) through a delivery roller (7), and is delivered into a continuous opening-and-closing double-extrusion die-head set where pre-impregnation is carried out upon the fiber bundle (4) and molten thermoplastic resin; the fiber bundle (4) is delivered into a impregnation calendaring roller, and is impregnated and subjected to primary setting, such that a continuous fiber belt (20) is formed; the continuous fiber belt (20) is delivered through a heating baking oven (21) and is directly subjected to creasing cooling setting through a creasing roller; the continuous fiber belt (20) is cut by using a cutter (24), and is rolled and set in a rolling device (25), such that a continuous fiber-reinforced thermoplastic material packing belt roll (26) is obtained. Compared with prior art, the packing belt provided by the invention has the advantages of no corrosion, higher strength, low elongation rate and low recovery rate, good continuous tension, good aging resistance, long service life, and the like.

Description

technical field [0001] The invention relates to a plastic packing belt and a manufacturing method thereof, in particular to a continuous fiber-reinforced thermoplastic material packing belt and a manufacturing method thereof. Background technique [0002] Most of the current packing belts are made of iron or ordinary plastic. Iron packing belts need to consume a lot of iron, and are easy to corrode and break, and the edges of the packing belts are sharp, dangerous to operate, easy to hurt hands and damage equipment. bundle objects. However, the tensile strength of the packing belt made of ordinary plastic is not enough, the elongation and recovery rate are high, the continuous tension is poor, and it is easy to weather in the natural environment. Contents of the invention [0003] The purpose of the present invention is to provide a continuous fiber-reinforced thermoplastic with no corrosion, higher strength, low elongation and recovery, good continuous tension, not easy ...
