TECHNICAL FIELD

[0001] The utility model relates to waterproof technical field especially is related to a waterproof roll composite strength on -line detection device. BACKGROUND

[0002] In the production process of the fiber inner reinforced thermoplastic polyolefin (TPO) waterproof roll, the composite process is a very important link, and the composite strength directly determines the service performance of the material. The production of the roll is a continuous production process, and timely detection of the composite strength of the material in the continuous production process is of great significance to the production and quality control of the roll. In the prior art, there is no effective on-line monitoring means in the production process, and the composite strength can only be detected by random sampling after the production is completed. The random sampling detection means after the production is completed has certain randomness and hysteresis, and cannot effectively monitor the production, so that the production cannot be adjusted in time, and the quality hidden danger of low composite strength cannot be found, resulting in high product scrap rate.

[0013] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0014] like Figures 1-3 As shown, an online testing device for the composite strength of waterproof membrane consists of a support 1, multiple closed transmission chains 2, multiple elastic adsorption mechanisms 3 installed on the transmission chains 2, and several rollers. The rollers include two active rollers 5, a first roller 61, a second roller 62, a third roller 71, and a fourth roller 72. The two active rollers 5, the first roller 61, the second roller 62, the third roller 71, and the fourth roller 72 together support the transmission chains 2 to form a closed chain, wherein the horizontal height of the third roller 71 and the fourth roller 72 is higher than the horizontal height of the first roller 61 and the second roller 62. The active rollers 5 are driven to rotate by a servo motor 4. The elastic adsorption mechanism 3 consists of a universal joint 31, a spring 32, a suction cup seat 33, and a suction cup 34. The elastic adsorption mechanism 3 is connected to the transmission chains 2 through the universal joint 31. A tension sensor and a wireless signal transmission device are installed inside the suction cup seat 33, and the suction cup 34 is made of high-strength silicone material. Multiple elastic adsorption mechanisms 3 are evenly installed on the transmission chain 2. Alternatively, the spring 32 can be replaced with a vacuum piston structure, and a one-way valve can be added so that the one-way valve is closed when the suction cup contacts the roll material and open when it leaves the roll material, so as to achieve a firm connection and release between the suction cup and the roll material.

[0015] Brief description of use process: the device is installed in the post-cutting section of the coiled material and before the coiled material winding process. It is controlled by PLC, and the signal is connected with the production line for data connection. The running speed of the transmission chain 2 is synchronized with the extrusion speed of the production line through the servo motor 4. When the waterproof coiled material 8 passes through the device, the suction cup is contacted with the waterproof coiled material under the driving of the transmission chain 2. The distance between the transmission chain and the support is adjusted to compress the spring, so that the suction cup is adsorbed on the surface of the coiled material. The height of the third roller 71 and the fourth roller 72 is adjusted, so that the spring is in the elongation state when the coiled material runs to the third roller 71. When the waterproof coiled material reaches the end of the support, the suction cup is separated from the surface of the waterproof coiled material. The monitoring density can be changed by changing the installation density of the elastic adsorption mechanism. The device tests whether the material meets the composite requirements by applying force to the upper surface of the coiled material. If the coiled material does not meet the composite requirements or the composite strength is not enough at the test site, the upper surface of the coiled material will be pulled up under the action of the suction cup and the tension spring. The tension of the spring will also change. The signal is transmitted to the external equipment for data statistics and processing through the tension sensor and the signal transmission device built in the suction cup seat.

[0016] Although the specific embodiments of the utility model have been described above with reference to the drawings, it is not a limitation on the protection scope of the utility model. For some technical contents known by ordinary skilled in the art, this place will not be repeated, and the skilled in the art should understand that various modifications or deformations made by the skilled in the art on the basis of the technical scheme of the utility model without creative labor are still within the protection scope of the utility model.
