Description

Technical Field

[0001] The utility model relates to the technical field of transmission systems, in particular to a medium transmission system for a chemical fiber direct injection color development machine. Background Art

[0002] The medium transmission system of the existing chemical fiber direct injection color development machine is as Figure 1 shown, including a feeding mechanism, an oven, a feeding guide roller, a discharging guide roller and a material receiving mechanism. The working principle is that the chemical fiber cloth with a digitally printed multicolor image passes through the oven at a certain speed under the action of the feeding mechanism and the material receiving mechanism, and the color is developed and fixed to produce a finished cloth. The temperature inside the oven can be heated to (180 - 210 degrees Celsius); the heat sublimation ink needs to reach 10 to 20 seconds inside the oven to develop and fix the color.

[0003] Disadvantages: 1. The first feeding is not convenient. The cloth needs to pass through the oven from the inlet to the outlet with the help of special tools, and the temperature inside the oven is very high.

[0004] 2. The path inside the oven is very short, and the color development time is fixed, so that the running speed of the machine is very slow and cannot meet the color development requirements of high-speed digital printers.

[0005] 3. The color development process cannot be paused. When it needs to stop, all the cloth needs to be withdrawn, and when color development is required, it needs to be fed again. Content of the Utility Model

[0006] The purpose of the utility model is to make up for the defects of the existing technology and provide a medium transmission system for a chemical fiber direct injection color development machine.

[0007] The utility model is realized by the following technical solutions:

[0008] A medium transmission system for a chemical fiber direct injection color development machine, including a cloth feeding mechanism, an oven, a lifting roller, a chain transmission mechanism, a feeding guide roller, a discharging guide roller and a cloth receiving mechanism. The bottom of the oven is open, and the oven is located above the middle part between the cloth feeding mechanism and the cloth receiving mechanism. The feeding guide roller and the discharging guide roller are installed below the oven. The feeding guide roller is close to the cloth feeding mechanism, and the discharging guide roller is close to the cloth receiving mechanism. The lifting roller is installed on the chain transmission mechanism. The chain transmission mechanism is located between the feeding guide roller and the discharging guide roller, and the chain transmission mechanism drives the lifting roller to move up and down.

[0009] The chain transmission mechanism includes a driving sprocket, a driven sprocket and a driving motor. The driving sprocket is located below the oven and lower than the feeding guide roller and the discharging guide roller. The driven sprocket is located above the inside of the oven. The driving motor drives the driving sprocket to rotate, and a chain is connected between the driving sprocket and the driven sprocket.

[0010] The lifting roller described above is installed on a lifting roller mounting plate, and the lifting roller mounting plate is fixed to the chain described above.

[0011] The advantages of the present utility model are as follows: 1. When the present utility model is fed for the first time, the lifting roller can be lowered to the lowest point, which is convenient for threading the material through the oven, and outside the oven, there is no high temperature.

[0012] 2. When the present utility model is working, the lifting roller rises to the highest point, increasing the travel of the fabric inside the oven. Under the same color development temperature and time, the operating speed of the machine is greatly increased, thereby improving the efficiency of the machine.

[0013] 3. When the color development is paused, the lifting roller can be lowered to the lowest point to retract the fabric outside the oven. When it is necessary to start, the lifting roller rises to continue the color development. BRIEF DESCRIPTION OF THE DRAWINGS
