Problems solved by technology

However, in the aforementioned prior art, when the transverse cloth slice is combined with the longitudinal cloth slice, the tension in the two directions differs greatly; in the way of stacking and compounding multiple pieces of material, the material is in a relaxed state during compounding
In the composite state of these two methods, there is the problem of unbalanced tension of the unidirectional fabric, which is not conducive to giving full play to the performance of the material. At the same time, the unbalanced tension will also affect the molding quality of the UD fabric product, and may even cause wrinkles in the composite fabric. or creases and other defects

Embodiment 1

[0072] like Figure 1-4 As shown, this embodiment relates to a compounding device that can control the tension of unidirectional cloth to stabilize, including a longitudinal unit, a transverse unit and a compounding unit. The longitudinal unit includes a longitudinal unwinding device 11, a first tension roller 12, a tension separation device 13 composed of a group of conveying rollers, a third tension roller 14, a winding device 15, and a longitudinal direction not shown in the figure. Unwinding power unit and rewinding power unit. The transverse unit includes a transverse unwinding device 21, a second tension roller 22, and a transverse unwinding power device not shown in the figure. The compounding unit includes a compounding platform 31, a hot-pressing roller 32, a clamping device 33, a cutting device 34, and an air blowing device 35, wherein the surface of the compounding platform 31 is provided with a high-temperature resistant rubber pad, and the hot-pressing roller 32 ...

Embodiment 2

[0093] The equipment of this embodiment is the same as that of Embodiment 1, and the difference lies in the compounding process. The compounding process of this embodiment is as follows: Figure 5 shown, the specific steps are as follows:

[0094] Step a): as Figure 5 As shown in a, in the initial state of the compounding process, the hot-pressing roller 32 is located at the left edge of the longitudinal unidirectional cloth 10, the rotating shaft of the hot-pressing roller 32 is in a braking state, and the hot-pressing roller 32 and the clamping device 33 will Clamp to the cloth 20;

[0095] In the initial state, the hot-pressing roller 32 and the clamping device 33 are in a clamping state. In the clamping state, the rotating shaft of the hot-pressing roller 32 is in a state of braking and cannot rotate, and the hot-pressing roller 32 and the clamping device are in a state of being braked and unable to rotate. 33 fits snugly, so the transverse unidirectional cloth 20 is cl...

Abstract

According to the unidirectional cloth compounding method capable of controlling the tension of the unidirectional cloth to be stable, compared with conventional unidirectional cloth compounding equipment, the longitudinal tension control device and the transverse tension control device are arranged, so that the tension of the transverse unidirectional cloth and the tension of the longitudinal unidirectional cloth can be kept stable in the compounding process; the influence of the looseness of the unidirectional cloth on the anti-elasticity performance of the compounded UD cloth is avoided, and the UD performance can be brought into full play. According to the unidirectional cloth compounding method provided by the invention, the hot pressing roller, the clamping device, the compounding platform and the tension control device are matched with one another, so that the unidirectional cloth is always in a tensioned state in the compounding process, the quality of the compounded UD cloth is improved, the performance of materials is fully utilized, the labor is saved, and the automation degree of UD cloth production is improved.

Description

technical field [0001] The invention belongs to the field of unidirectional cloth compounding methods, and more particularly relates to a compounding device and a unidirectional cloth compounding method capable of controlling the unidirectional cloth tension to be stable. Background technique [0002] The strength of Uni-directional Cloth (also known as UD cloth) is concentrated in a specific direction (such as the length direction), and it has excellent properties such as softness, low density, wear resistance, impact resistance, cutting resistance and strong toughness. The products are widely used. It is used in soft body armor, lightweight bulletproof helmet, lightweight bulletproof armor plate, stab-resistant, cut-resistant clothing lining and special public explosion-proof facilities. A plurality of unidirectional cloths are stacked and laminated in sequence at a certain angle to form a composite cloth. [0003] In the conventional composite fabric processing equipment...
