# Title
Continuous Roll-To-Roll LB Film Deposition Machine


# Problem Statement
The large-scale production of lb film has great economic potential, but there are technical problems. At present, the world has failed to achieve large-scale mass production of lb film, and the development cost is extremely expensive.

# Solution Overview
This project is aimed at solving the mass production problem of LB film using a continuous roll-to-roll production method which can make a great contribution to the industry application of LB film.

# Solution Components
The project consists of three parts:

1. The production system, including stainless steel tanks, is used for loading liquid solvents on which nanomaterials float. Above one side of the slot is a nanomaterial burette for adding nanomaterial to the slot, which is controlled by a computer system.
2. The collection system consists of a bracket and five stainless steel rolls, two of which are used to collect Ptes with nanomaterials attached to the surface and three of which are used to adjust the slope of the contact area. The reel is connected to the transmission and motor and is controlled by a computer system.
3. Electromechanical control system with all computer components built in, used to adjust the traditional speed, find the best production conditions, control the operation of the system.

# Software Components:
1. The speed of stainless steel drum operation is adjusted by setting the code, and the speed is expected to be 0.55-20 mm per minute. Therefore, it is necessary to visualize the speed of stainless steel through the computer and observe the production results in time.
2. The height of the stainless steel drum is controlled by a computer to achieve different slopes of the film in order to find and stabilize the best Angle of tension diffusion to achieve maximum production efficiency.

# Criterion for Success
1. Find the best moving speed of rolling speed, syringe pump speed and angle between interface and film surface.
2. Solve the problem of material will gp through the film from two sides.
3. Achieve the production of regularly LB film.

# PROBLEM

Tea is a popular beverage but cannot be easily obtained like coffee because no machine on the market can make it as convenient to drink tea as a coffee machine. Additionally, people’s requirements for the type and strength of tea are just as complex as those for coffee. We want to design a device that allows users to input the type of tea they want to drink and their taste preferences and then receive a cup of tea that meets their requirements.”

# SOLUTION OVERVIEW

This machine has a total of five systems: an interactive subsystem that receives user input, a control subsystem that controls all other subsystems, a solid storage subsystem for storing tea leaves, a tea brewing subsystem that adds an appropriate amount of water at the right temperature, and a flavour subsystem for adding additional ingredients such as milk and sugar.

# SOLUTION COMPONENTS

##INTERACTIVE SUBSYSTEM

The interactive subsystem includes a series of digital displays and buttons for users to adjust parameters related to taste, such as tea strength, temperature, and concentration of additional ingredients. It is also capable of delivering this data to the control subsystem.

## CONTROL SUBSYSTEM

The control subsystem is capable of transmitting signals to other subsystems and can control the number of tea leaves and additional ingredients used, as well as the temperature and amount of water used, and the overall brewing time.

## TEA BREWING SUBSYSTEM

The tea brewing subsystem includes a mixing tank that can store the added tea leaves, water, and additional ingredients and can dispense the brewed tea and tea leaves together at the set time.

## FLAVOR SUBSYSTEM

The flavouring subsystem includes tanks for storing syrup and milk, as well as pipelines and valves for adding a predetermined amount of syrup and milk based on instructions from the control subsystem.

# CRITERION FOR SUCCESS

After users set their taste preferences on the front-end interface, they can wait for a certain amount of time and then enjoy a cup of tea that meets their preferences. After each tea-making process, the machine’s interior is relatively clean and there are no residual tea leaves that could affect the taste or food safety.

# DISTRIBUTION OF WORK

Zhiyuan Wang is responsible for designing the mechanical structure, including the outer shell, storage compartment, and liquid pipelines. Anyu Ying is responsible for designing and soldering the circuit board. Zhenzuo Si and Ruiqi Ye are responsible for developing and debugging the control and interaction systems.
