Abstract
Description
Technical Field
[0001] This utility model relates to the field of low elasticity yarn production technology, specifically a heating device for low elasticity yarn production. Background Technology
[0002] Polyester low-elasticity yarn is a type of textured yarn of polyester chemical fiber. It is made from polyester chips as raw material, using high-speed spinning of pre-oriented polyester yarn, and then processing by stretching and false twisting. It has the characteristics of short process, high efficiency and good quality. Texturing of polyester low-elasticity yarn can be processed by a texturing machine. A texturing machine is a textile machine that can process untwisted yarns such as polyester and polypropylene into elastic yarns with medium and low elasticity through false twisting. When texturing polyester low-elasticity yarn, it is necessary to heat the polyester low-elasticity yarn.
[0003] Existing heating equipment for producing low-elasticity yarn mostly heats polyester low-elasticity yarn through heating plates. The temperature is higher on the side of the heating box closer to the heating plate and lower on the side farther away from the heating plate, resulting in uneven temperature distribution within the heating box. Consequently, the polyester low-elasticity yarn is not heated evenly. At the same time, the heating heat cannot be recycled during the heating process, resulting in significant heat waste. Utility Model Content

[0008] In order to support the polyester low-elasticity yarn, as a preferred heating device for low-elasticity yarn production according to the present invention, the rear end of the heating chamber is rotatably connected with a plurality of support rollers distributed on the left and right and located between two sets of drive rollers.
[0009] In order to drive the two sets of drive rollers to rotate, in a preferred embodiment of the heating equipment for producing low-elasticity yarn according to this utility model, both sets of drive rollers are driven by a drive box installed on the rear end face of the heating box.
[0010] In order to detect the temperature inside the heating chamber, a temperature sensor is preferably installed at the rear end of the heating chamber, which is a preferred heating device for producing low-elasticity yarn according to this utility model.

[0013] Multiple heating tubes heat the air inside the first and second heating chambers. Then, through the cooperation of the first fan, the second fan, two third fans, and two fourth fans, the heated air inside the heating chamber circulates in the direction of the arrows shown in the figure, thereby making the temperature distribution in the heating chamber uniform and heating the polyester low-elasticity yarn evenly. At the same time, the heating heat is recycled.

[0020] Multiple evenly distributed drive rollers 9 are rotatably connected to the rear end of the heating chamber 4. Two drive rollers 9 located on the same vertical axis form a group. The left and right side walls of the heating box 1 are provided with through holes 10 that communicate with the heating chamber 4. The two through holes 10 and the two groups of drive rollers 9 are located at the same height.
[0021] In this embodiment: When in use, the box door 16 is opened, and then the polyester low elastic yarn passes through the two through holes 10 into the heating chamber 4, so that the polyester low elastic yarn is located between the two sets of drive rollers 9. At the same time, the polyester low elastic yarn is located above the multiple support rollers 12, and then the box door 16 is closed.
[0022] After preparation, the first fan 18, the second fan 6, two third fans 7, two fourth fans 8, and multiple heating tubes 11 are started. The heating tubes 11 heat the air inside the first heating chamber 3 and the second heating chamber 5. Then, the first fan 18 draws the heated air from the first heating chamber 3 into the heating chamber 4. The second fan 6 then draws the air from the heating chamber 4 into the second heating chamber 5. The two third fans 7 then draw the heated air from the second heating chamber 5 into the heating chamber 4. Finally, the two fourth fans 8 draw the air from the heating chamber 4 into the first heating chamber 3. Through the coordinated operation of the first fan 18, the second fan 6, the two third fans 7, and the two fourth fans 8, the air in the heating chamber 1 is heated according to… Figure 2 The direction of the arrow drawn in the figure is cyclical, which makes the temperature distribution in the heating chamber 4 uniform, and heats the polyester low elastic yarn evenly. At the same time, the heating heat is recycled.
[0023] While the heated air circulates, the two sets of drive rollers 9 rotate, which in turn drive the polyester low elastic yarn to move from left to right, thereby heating the polyester low elastic yarn.
[0024] As a technical optimization of this utility model, multiple heating tubes 11 distributed front to back are installed at the upper inner end of the first heating cavity 3 and the lower inner end of the second heating cavity 5.
[0025] In this embodiment, multiple heating tubes 11 can heat the air inside the first heating chamber 3 and the second heating chamber 5.
[0026] As a technical optimization of this utility model, the rear end of the heating cavity 4 is rotatably connected to a plurality of support rollers 12 distributed on the left and right and located between two sets of drive rollers 9.
[0027] In this embodiment, multiple support rollers 12 can support the polyester low elasticity yarn and prevent the polyester low elasticity yarn from sagging and bending.

[0030] As a technical optimization of this utility model, a temperature sensor 14 is installed at the rear end of the heated cavity 4.
[0031] In this embodiment, the temperature sensor 14 can detect the temperature inside the heating chamber 4. When the temperature inside the heating chamber 4 is too high, the temperature sensor 14 sends a signal to the control processing unit. The control processing unit controls multiple heating tubes 11 to reduce the heating temperature to prevent the high temperature from damaging the polyester low elastic yarn.
[0032] As a technical optimization of this utility model, the front end face of the heating box 1 is provided with an installation notch 15 that communicates with the heating chamber 4. The installation notch 15 is equipped with a box door 16. The front end face of the box door 16 is equipped with a control panel 17, which is equipped with a control processing unit. The control panel 17 is electrically connected to the first fan 18, the second fan 6, two third fans 7, two fourth fans 8, multiple heating tubes 11, the drive box 13, and the temperature sensor 14.
[0033] In this embodiment: the door 16 facilitates the laying of polyester low-elasticity yarn passing through the heating chamber 4, and the control panel 17, together with the control processing unit, facilitates the control of the first fan 18, the second fan 6, the two third fans 7, the two fourth fans 8, the multiple heating tubes 11 and the drive box 13.
[0034] Working principle: When in use, open the box door 16, and then pass the polyester low elastic yarn through the two through holes 10 into the heating chamber 4, so that the polyester low elastic yarn is located between the two sets of drive rollers 9. At the same time, the polyester low elastic yarn is located above the multiple support rollers 12, and then close the box door 16.
[0035] After preparation, the control panel 17 controls the operation of the first fan 18, the second fan 6, two third fans 7, two fourth fans 8, multiple heating tubes 11, and the drive box 13 via the control processing unit. The multiple heating tubes 11 heat the air inside the first heating chamber 3 and the second heating chamber 5. Then, the first fan 18 draws the heated air from the first heating chamber 3 into the heating chamber 4. The second fan 6 then draws the air from the heating chamber 4 into the second heating chamber 5. The two third fans 7 then draw the heated air from the second heating chamber 5 into the heating chamber 4. Finally, the two fourth fans 8 draw the air from the heating chamber 4 into the first heating chamber 3. Through the coordinated operation of the first fan 18, the second fan 6, the two third fans 7, and the two fourth fans 8, the air heated in the heating box 1 is adjusted according to... Figure 2 The direction of the arrow drawn in the figure is cyclical, which makes the temperature distribution in the heating chamber 4 uniform, and heats the polyester low elastic yarn evenly. At the same time, the heating heat is recycled.
