Abstract
Description
Technical Field
[0001] This utility model belongs to the field of flexible material composite technology, and in particular relates to a micro-tension composite device. Background Technology
[0002] Waterproof and breathable membranes are a new type of flexible polymer waterproof material. Due to their unique fibrous microporous structure, they possess multiple functions including waterproofing, breathability, and sound transmission. They can prevent water droplet intrusion while allowing gas inside the structure to escape rapidly, quickly balancing the pressure difference between the inside and outside of the structure. In some scenarios with voice interaction capabilities, they can even achieve low-loss voice transmission. With the increasing demand for waterproofing, especially in consumer electronics and other fields, the requirements for waterproofing are also rising, leading to increasingly stringent technical requirements. Waterproof and breathable membranes, primarily based on ultra-thin EPTFE films, are easily stretched and deformed during the composite processing. This deformation directly affects the response efficiency of air pressure balance and sound transmission distortion, making them unsuitable for various application scenarios. Therefore, controlling the composite tension of waterproof and breathable membranes is becoming increasingly crucial. Utility Model Content

The frame 13 includes a base, a platform, and a support. The base is located at the bottom of the frame 13, the platform is mounted on the top of the base, and the support is mounted on the top of the platform. The EPTFE waterproof and breathable membrane feeding mechanism, the guiding mechanism, and the balancing mechanism are all mounted on the crossbeams of the support. The bottom material feeding mechanism is mounted on the left side of the base, the composite mechanism is mounted on the platform, and the receiving mechanism is mounted on the right side of the base. The EPTFE waterproof and breathable membrane feeding mechanism is located to the left of the guiding mechanism, the guiding mechanism is located to the left of the balancing mechanism, and the balancing mechanism is located to the left of the composite mechanism.
[0034] In a preferred embodiment of this invention, the microcontroller module is electrically connected to the EPTFE waterproof and breathable membrane feeding mechanism, the bottom material feeding mechanism, the laminating mechanism, and the collecting mechanism, respectively. In this embodiment, the microcontroller module adjusts the feeding speed of the EPTFE waterproof and breathable membrane feeding mechanism in real time according to the equilibrium state; adjusts the feeding speed of the bottom material feeding mechanism in real time according to the feeding speed of the EPTFE waterproof and breathable membrane feeding mechanism; adjusts the laminating speed of the laminating mechanism on the EPTFE waterproof and breathable membrane and the bottom material according to the feeding speed of the EPTFE waterproof and breathable membrane feeding mechanism and the bottom material feeding mechanism; and adjusts the collecting speed of the collecting mechanism on the finished product according to the laminating speed of the laminating mechanism on the EPTFE waterproof and breathable membrane and the bottom material.

The floating roller 2 and the counterweight 3 are located on the left and right sides of the angle sensor 1, respectively. Both the floating roller 2 and the counterweight 3 are vertically downward under the action of gravity. The angle sensor 1 is connected to the microcontroller module. An EPTFE waterproof and breathable membrane is tightly attached to the bottom of the floating roller 2 and is subjected to force at the bottom of the floating roller 2. In this embodiment, the initial state of the balancing mechanism is a balanced state. At this time, the force on the EPTFE waterproof and breathable membrane is equal to (weight of floating roller 2 - counterweight 3) / 2. If the force on the EPTFE waterproof and breathable membrane increases or decreases, the angle sensor 1 rotates to the right or left.
