Description

Technical Field

[0001] The invention relates to the technical field of fabric preparation devices, and in particular to a device and process for preparing breathable Tencel blended fabrics. Background Art

[0002] The breathability of Tencel usually comes from the characteristics of the fiber itself. It can effectively absorb and release moisture, making the skin feel more comfortable. Blended fabrics refer to fabrics made by mixing different fibers together. They can combine the advantages of various fibers and improve the performance and feel of the fabric.

[0003] In the prior art, a high-efficiency thermal setting device and method for fabrics (publication number: CN117449058A) can issue an alarm when the fabric tension is too tight or too loose during fabric setting through a movable monitoring roller and a fixed first and second alarms and a first and second copper blocks, thereby prompting the staff that problems with the fabric tension need to be dealt with in a timely manner, thereby avoiding continuing to set the fabric after problems with the fabric tension occur, resulting in poor fabric setting quality. However, the device needs to open the setting box each time the material is loaded before the fabric can be wound around the inside of the device. To ensure the safety of the operator, the setting box needs to be cooled before the operation can be performed, which reduces the working efficiency of the fabric setting, and the setting box is reheated, resulting in high energy consumption. Therefore, it is urgent to design a more energy-saving and efficient breathable Tencel blended fabric preparation device and process. Summary of the invention

[0012] A method for using a device for preparing a breathable Tencel blended fabric comprises the following steps:

[0013] Step 1: When replacing the cloth to be shaped, first drive the traction mechanism to the feeding port of the shaping box body, then insert one end of the cloth to be shaped into the traction bracket, and flatten the end of the cloth so that both sides are located between the upper and lower rollers, and then start the second motor to drive the upper and lower rollers to clamp the cloth;

[0014] Step 2: Start the first motor to drive the traction mechanism to slide toward the discharge port at the other end of the shaping box body, and then bring one end of the cloth to be shaped to the discharge port, so that the shaping box body can be loaded without opening the box, and then the end of the cloth is wound in the winding device;

[0015] Step 3: Drive the traction mechanism to the middle position inside the shaping box body, and adjust the two adjacent lifting blocks to an appropriate distance, so that the two rollers are in a free rotation state, and at the same time, the surfaces of the two rollers are respectively against the surfaces of the two sides of the cloth to be shaped. Driven by the cloth, the roller rotates, and the surrounding hot air is concentrated inside the roller through the fan blades inside it, and the concentrated hot air flow acts on the edge of the cloth through the hollow structure on the surface of the roller, so as to avoid the problem of insufficient heat setting of the edge of the cloth and easy wrinkles;

[0016] Step 4: During the heat setting process, two adjacent insulation doors drive two sealing rollers to contact the surfaces of both sides of the fabric. The sealing rollers can flatten the fabric surface before and after setting, so that the fabric setting effect is better.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] 1. By setting up a traction mechanism, when the cloth to be shaped needs to be loaded, it is only necessary to flatten one end of the cloth and insert it into the traction bracket and place it between the upper and lower rollers, and then start the second motor to drive the active bevel gear to drive the driven bevel gear, and the driven bevel gear drives the bidirectional screw to rotate, thereby driving the two lifting blocks on the same side to slide toward each other, and then driving the two rollers to clamp the upper and lower sides of one end of the cloth, so that the cloth can follow the traction mechanism from the feed port at one end of the shaping box body to the discharge port at the other end, avoiding loading after unpacking and cooling, thereby improving the working efficiency of the equipment, while reducing the heat loss inside the box, reducing energy loss, and improving the energy-saving effect of the equipment;

[0019] 2. By setting the limit shaft, when the upper and lower adjacent rollers clamp the fabric, the lifting block drives the limit shaft to slide out of the second slide groove, and then pushes the limit shaft to insert into the corresponding roller to prevent the roller from rotating during the process of clamping the fabric, thereby improving the stability of the equipment operation process. At the same time, the two rollers can be adjusted by the lifting block so that the upper and lower adjacent rollers are in a free rotation state and abut against the surfaces of both sides of the fabric. When the fabric passes through the shaping box body, the two rollers are driven to rotate. When the rollers are in a free rotation state, the traction bracket slides to the middle of the shaping box body. During the rotation of the two rollers, the fan blades inside the two rollers attract the hot air near the traction bracket into the inside of the roller, and then the hollow structure on the surface of the roller acts on the edge of the fabric, so as to finely shape the edge of the fabric, thereby preventing the edge of the fabric from being inadequately shaped, thereby improving the shaping effect of the equipment.

[0020] 3. By setting the first isolation block and the heat-insulating door, under the pushing force of the spring rod, the two heat-insulating doors slide toward each other until the two sealing rollers respectively rest against the upper and lower surfaces of the cloth. When there is no cloth between the two heat-insulating doors, the inlet and outlet channels of the shaping box body can be blocked by multiple first isolation blocks and multiple heat-insulating doors to reduce the internal heat loss, avoid restarting the equipment for heating after each material change, and waste energy, thereby improving the energy-saving and heat-insulating effect of the equipment.
