Description

Technical Field

[0001] This utility model relates to the field of temperature control technology, and in particular to a temperature control device for a heating roller. Background Technology

[0002] In fabric production, heating rollers are typically used during fabric conveying to heat and shape the fabric or to eliminate air bubbles on the fabric surface. The fabric passes over the surface of these rollers. In the fabric shaping process, the fabric needs to be preheated before high-temperature shaping; the preheating temperature is usually lower than the high-temperature shaping temperature. Existing heating rollers generally use steam heating. To control the temperature of the preheating roller and the high-temperature shaping roller separately, they need to be connected to corresponding steam generators, and their temperatures need to be controlled separately, which is cumbersome. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a temperature control device for a heating roller, thereby reducing the difficulty of temperature control of the heating roller.

[0004] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0005] A temperature control device for a heating roller includes a steam generator, a first steam inlet pipe, and a second steam inlet pipe;

[0006] The steam generating device has a first steam outlet and a second steam outlet arranged sequentially from top to bottom;

[0007] The first steam outlet is connected to the first heating roller through the first steam inlet pipe, and the second steam outlet is connected to the second heating roller through the second steam inlet pipe, so that the first heating roller and the second heating roller have different surface temperatures.

[0008] Furthermore, the temperature control device also includes a third steam inlet pipe and a valve;

[0009] The third steam inlet pipe is connected to the third heating roller;

[0010] The valve is connected to the second steam outlet, and the second steam inlet pipe and the third steam inlet pipe are respectively connected to the valve. The valve is used to control the amount of air entering the third steam inlet pipe.

[0011] Furthermore, the valve is a three-way valve.

[0012] Furthermore, the height difference between the first steam outlet and the second steam outlet is 50cm to 100cm.

[0013] Furthermore, the first steam outlet is located at the top of the steam generating device.

[0014] Furthermore, the second steam outlet is located on the side wall of the steam generator.

[0015] Furthermore, the first heating roller, the second heating roller, and the third heating roller are arranged sequentially from top to bottom and are parallel to each other.

[0016] Furthermore, the first steam inlet pipe, the second steam inlet pipe and / or the third steam inlet pipe are provided with a heat insulation layer.

[0017] Furthermore, the insulation layer is detachably disposed outside the first steam inlet pipe, the second steam inlet pipe, and / or the third steam inlet pipe.

[0018] Furthermore, the first steam inlet pipe is detachably connected to the first steam outlet.

[0019] The beneficial effects of this invention are as follows: Based on the principle of hot air rising, the amount of hot steam varies at different heights of the steam generator. Therefore, by setting steam outlets at different heights of the steam generator and connecting the different steam outlets to the corresponding heating rollers through the first and second steam inlet pipes, different heating rollers can have different surface temperatures. This allows the first and second heating rollers to preheat and set the fabric at high temperatures respectively, reducing the difficulty of temperature control. Attached Figure Description

[0024] 2. First steam inlet pipe; 3. Second steam inlet pipe; 4. First heating roller; 5. Second heating roller; 6. Third steam inlet pipe; 7. Valve; 8. Third heating roller. Detailed Implementation

[0025] To explain in detail the technical content, objectives, and effects of this utility model, the following description is provided in conjunction with the embodiments and accompanying drawings.

[0026] Please refer to Figure 1 and Figure 2A temperature control device for a heating roller includes a steam generating device 1, a first steam inlet pipe 2, and a second steam inlet pipe 3. The steam generating device 1 has a first steam outlet 11 and a second steam outlet 12 arranged sequentially from top to bottom. The first steam outlet 11 is connected to a first heating roller 4 through the first steam inlet pipe 2, and the second steam outlet 12 is connected to a second heating roller 5 through the second steam inlet pipe 3, so that the first heating roller 4 and the second heating roller 5 have different surface temperatures.

[0027] Understandably, based on the principle of hot air rising, the amount of hot steam varies at different heights of the steam generator 1. Therefore, by setting steam outlets at different heights of the steam generator 1 and connecting the different steam outlets to the corresponding heating rollers through the first steam inlet pipe 2 and the second steam inlet pipe 3, different heating rollers can have different surface temperatures. This allows the first heating roller 4 and the second heating roller 5 to preheat and set the fabric at high temperatures, respectively, reducing the difficulty of temperature control.

[0028] In some embodiments, the temperature control device further includes a third steam inlet pipe 6 and a valve 7; the third steam inlet pipe 6 is connected to the third heating roller 8; the valve 7 is connected to the second steam outlet 12, and the second steam inlet pipe 3 and the third steam inlet pipe 6 are respectively connected to the valve 7, which is used to control the air intake of the third steam inlet pipe 6. Preferably, the valve 7 is a three-way valve. By controlling the steam intake of the third steam inlet pipe 6 through the valve 7, the heating temperature of the third heating roller 8 can be controlled, so that the first heating roller 4, the second heating roller 5, and the third heating roller 8 can obtain different surface temperatures to meet the usage requirements of different application scenarios.

[0029] In some embodiments, the height difference between the first steam outlet 11 and the second steam outlet 12 is 50cm to 100cm. The greater the height difference between the first steam outlet 11 and the second steam outlet 12, the greater the temperature difference between the first heating roller 4 and the second heating roller 5, and vice versa. The height difference between the first steam outlet 11 and the second steam outlet 12 can be set according to actual needs to achieve the corresponding temperature difference between the first heating roller 4 and the second heating roller 5.

[0030] In some embodiments, the first steam outlet 11 is located at the top of the steam generator 1. Since the amount of steam in the upper layer is lower than that in the lower layer, in order to ensure full utilization of the steam, the first steam outlet 11 is opened at the top of the steam generator 1 so that the steam is discharged more concentratedly.

[0031] In some embodiments, the second steam outlet 12 is located on the side wall of the steam generator 1. The second steam outlet 12 is opened on the side wall of the steam generator 1 so that steam is discharged from different heights, thereby allowing the first heating roller 4 and the second heating roller 5 to obtain different surface temperatures.

[0032] In some embodiments, the first heating roller 4, the second heating roller 5, and the third heating roller 8 are arranged sequentially from top to bottom and parallel to each other, so that the fabric is heated sequentially by the first heating roller 4, the second heating roller 5, and the third heating roller 8.

[0033] In some embodiments, the first steam inlet pipe 2, the second steam inlet pipe 3, and / or the third steam inlet pipe 6 are provided with an insulation layer. The insulation layer can reduce heat loss, and the corresponding steam inlet pipe can be wrapped with an insulation layer according to the actual situation, thereby increasing the surface temperature of the corresponding heating roller.

[0034] In some embodiments, the insulation layer is detachably disposed outside the first steam inlet pipe 2, the second steam inlet pipe 3 and / or the third steam inlet pipe 6, so as to provide insulation for the corresponding steam inlet pipes according to actual needs.

[0035] In some embodiments, the first steam inlet pipe 2 is detachably connected to the first steam outlet 11, and the second steam inlet pipe 3 is detachably connected to the second steam outlet 12, which facilitates the replacement and maintenance of the steam inlet pipes.

[0036] Embodiment 1 of this utility model is as follows:

[0037] A temperature control device for a heating roller includes a steam generating device 1, a first steam inlet pipe 2, and a second steam inlet pipe 3. The steam generating device 1 has a first steam outlet 11 and a second steam outlet 12 arranged sequentially from top to bottom. The first steam outlet 11 is connected to a first heating roller 4 through the first steam inlet pipe 2, and the second steam outlet 12 is connected to a second heating roller 5 through the second steam inlet pipe 3, so that the first heating roller 4 and the second heating roller 5 have different surface temperatures.

[0038] In this embodiment, the temperature control device further includes a third steam inlet pipe 6 and a valve 7; the third steam inlet pipe 6 is connected to the third heating roller 8; the valve 7 is connected to the second steam outlet 12, and the second steam inlet pipe 3 and the third steam inlet pipe 6 are respectively connected to the valve 7, which is used to control the air intake of the third steam inlet pipe 6. Preferably, the valve 7 is a three-way valve.

[0039] In this embodiment, the height difference between the first steam outlet 11 and the second steam outlet 12 is 100cm.

[0040] In this embodiment, the first steam outlet 11 is located at the top of the steam generator 1, and the second steam outlet 12 is located on the side wall of the steam generator 1.

[0041] In this embodiment, the first heating roller 4, the second heating roller 5, and the third heating roller 8 are arranged sequentially from top to bottom and are parallel to each other.

[0042] In this embodiment, the first steam inlet pipe 2, the second steam inlet pipe 3 and / or the third steam inlet pipe 6 are provided with a heat insulation layer.

[0043] In this embodiment, the insulation layer is detachably disposed outside the first steam inlet pipe 2, the second steam inlet pipe 3 and / or the third steam inlet pipe 6.

[0044] In this embodiment, the first steam inlet pipe 2 is detachably connected to the first steam outlet 11, and the second steam inlet pipe 3 is detachably connected to the second steam outlet 12.

[0045] The working principle of this utility model is as follows:

[0046] When the steam generator 1 starts to generate steam, the steam flows from bottom to top and first flows out from the second steam outlet 12 and then from the first steam outlet 11, so that there is a temperature difference between the surfaces of the first heating roller 4 and the second heating roller 5, thereby making the temperature of the first heating roller 4 lower than that of the second heating roller 5, which is used to preheat the fabric. When the valve 7 is opened, the surface of the third heating roller 8 will also have a certain temperature according to the opening degree of the valve 7.
