Description

Technical Field

[0001] The utility model belongs to the technical field of non-woven fabric production, in particular to a glass fiber feeding device for longitudinally and transversely reinforced tire-based non-woven fabric. Background Art

[0002] Polyester spunbond filament base non-woven fabric is widely used in tarpaulin waterproof membrane due to its high breaking strength, good tear resistance, high elongation at break and resilience. However, since polyester is a thermoplastic polymer, the main disadvantage of making it into a base fabric is that it is prone to dimensional instability under the high temperature and tension during the processing of waterproof membranes.

[0003] The produced roll materials are prone to slippage and leakage at the joints and edges of the facade walls after construction due to the elasticity of the roll materials, while the glass fiber base cloth is corrosion-resistant, high-temperature-resistant, and has good tensile strength. During the asphalt impregnation process, it has good dimensional stability under high temperature. Its disadvantages are brittleness, poor elasticity, and poor tear resistance. It is prone to damage and leakage after being made into roofing felt.

[0004] At present, longitudinally reinforced polyester spunbond filament base nonwoven fabrics have been used, but there is still a problem of insufficient dimensional stability in the transverse direction. The current reinforcement equipment cannot achieve transverse reinforcement. Therefore, designing a feeding device that can ensure stable feeding in both longitudinal and transverse directions is a problem that needs to be solved by the staff in this field. Utility Model Content

[0005] The utility model aims to provide a glass fiber feeding device for longitudinally and transversely reinforced tire base non-woven fabrics. By designing a new device, glass fiber mesh cloth of selected specifications is fed between two layers of polyester spunbond filament cotton meshes while ensuring that the glass fiber filaments therein are kept stretched and the tension is stable, so that the polyester spunbond filament non-woven fabrics are reinforced with glass fibers in both longitudinal and transverse directions for composite processing, thereby obtaining a new composite tire base cloth with excellent performance, which is a step up in performance compared with the glass fiber composite polyester tire base cloth only reinforced in the longitudinal direction.

[0006] In order to solve the above technical problems, the utility model is realized by the following technical solutions:

[0007] The utility model is a glass fiber feeding device for longitudinally and transversely reinforced tire base non-woven fabrics, comprising a lower platform, a middle platform, an upper platform, a reinforcement cloth transmission line, a web laying machine and two cotton web spinning machines;

[0008] The reinforcement cloth transmission line includes a reinforcement cloth unwinding machine, a cloth storage rack, a tension rack, a traction mechanism and an expansion mechanism connected in sequence;

[0009] The reinforcing cloth unwinding machine, cloth storage rack, tension rack and traction mechanism are sequentially installed on the top of the upper platform;

The two swing wire mechanisms are respectively arranged directly below the two cotton web spinning machines, and the two swing wire mechanisms are respectively connected to the two cotton web spinning machines;

[0012] A reinforcing cloth feeding mechanism is provided on the top of the web laying machine and between the two swinging wire mechanisms, and the traction mechanism and the width expansion mechanism are vertically distributed up and down and arranged just above the reinforcing cloth feeding mechanism;

[0013] The expansion mechanism is composed of a large drum-shaped steel roller and a small drum-shaped steel roller.

[0014] Furthermore, the reinforcement cloth unwinding machine is provided with a glass fiber mesh cloth coil, and the cloth storage rack is provided with a feeding roller group on the side close to the reinforcement cloth unwinding machine. The glass fiber mesh cloth coil is introduced into the cloth storage rack through the feeding roller group, and the input end of the feeding roller group is connected to the first driving mechanism.

[0015] Furthermore, it also includes a control device, which includes a processor and a plurality of control units. A tension roller is provided in the tension frame, and a detection probe is provided on the tension roller. The detection probe and the first driving mechanism are both electrically connected to the processor.

[0016] Furthermore, the traction mechanism is arranged on the top of the upper platform, the expansion mechanism is arranged above the web laying machine, and the reinforcement mesh between the traction mechanism and the expansion mechanism passes through the upper platform and the middle platform.

[0017] Furthermore, the traction mechanism is composed of an active steel roller and a driven rubber pressure roller, the active steel roller is connected to a second drive mechanism, the web laying machine is provided with a third drive mechanism, the output ends of the second drive mechanism and the third drive mechanism are both provided with encoders, and the second drive mechanism, the third drive mechanism and the two encoders are all electrically connected to the processor.

[0018] Furthermore, the reinforcing cloth feeding mechanism is composed of two feeding rollers, and the large drum-shaped steel roller is close to the two feeding rollers.

[0019] The utility model has the following beneficial effects:

[0020] 1. The utility model designs a novel device to feed glass fiber mesh cloth of selected specifications between two layers of polyester spunbond filament cotton nets while ensuring that the glass fiber filaments therein remain stretched and in a stable tension state, so as to achieve composite processing by reinforcing the polyester spunbond filament non-woven fabric with glass fibers in both longitudinal and transverse directions, thereby obtaining a new composite tire base cloth with excellent performance, which is a step up in performance compared with the glass fiber composite polyester tire base cloth reinforced only in the longitudinal direction.

[0021] 2. The utility model plays the function of cloth storage and buffering through the design of the cloth storage rack. At the same time, it cooperates with the detection probe on the rear tension rack to form a highly stable tension adjustment system. Cooperating with the subsequent expansion mechanism, the drum-shaped surface of the steel roller of the expansion mechanism makes the mesh cloth slide toward the two ends of the steel roller, thereby forming a certain lateral tension, which can achieve the stability of the tension of the glass fiber in both the vertical and horizontal directions in a convenient way.
