[0002] Tentering drying setting process technology is the most widely used finishing technology in textile printing and dyeing finishing process. It is suitable for tentering drying setting process of various types of fabrics such as woven fabrics, knitted fabrics, non-woven fabrics, non-woven fabrics, furs and leathers, and composite fabrics. During the chemical or physical processing of fabric in bleaching, dyeing, printing and other processes, the fabric is affected by various external forces. The fabric becomes radially elongated, weft shrinks, width is uneven and weft is skewed, and other problems of fabric dimensional stability. It needs to be corrected through tentering, drying and setting finishing. Tentering, drying and setting are to control the width of cotton, silk and wool fabrics and certain moisture-absorbing chemical fibers containing a certain amount of moisture to a specified size in the tentering machine, and to dry and eliminate internal stress to adjust the state of the fabric, so that the fabric width is neat and uniform, and the size is stable.

[0003] The Chinese invention patent with publication number CN110725090A discloses a double-layer tentering setting device and system, which is composed of two groups of setting machines arranged above and below and separated by a partition plate. A single group of setting machines generates heat by burning through a burner, and under the action of a fan, the heat is transmitted from the combustion chamber to the upper and lower air outlet pipe groups through the air chamber and the fixed shell. The upper and lower air outlet pipe groups spray hot air to tenter and set the textile products.

[0004] However, in the above-mentioned prior art double-layer tentering setting device, in order to adjust the amount of gas sprayed from the air outlet holes of the upper and lower air outlet pipe groups, the operator needs to manually control the rotation angle of the air valve to control the amount of gas sprayed from the air outlet holes of the upper and lower air outlet pipe groups. However, the required air volume is different for different types of fabric in different setting processes (for example, pre-setting, post-dyeing setting, finished product setting, etc.).

[0078] Based on the technical scheme of the inner-outer double-layer setting device 100 disclosed in the foregoing embodiments, the present embodiment further discloses a double-layer tentering setting device 200.

[0079] Referring to Figure 11 As shown in the figure, in the present embodiment, the double-layer tentering setting device 200 comprises a box body 201, at least one inner-outer double-layer setting device 100 as disclosed in the foregoing embodiments arranged axially in the box body 201, a first tentering mechanism 202 arranged in the box body 201 and formed between the first air outlet pipe group 301 and the second air outlet pipe group 302 to tenter the textile fabric, and a second tentering mechanism 203 formed between the third air outlet pipe group 303 and the fourth air outlet pipe group 304 to tenter the textile fabric. The first tentering mechanism 202 and the second tentering mechanism 203 tenter the two layers of textile fabric arranged in the upper and lower positions, respectively. It should be noted that the box body 201 can be a support structure such as a frame or a plate, as long as it can support the first tentering mechanism 202, the second tentering mechanism 203 and the inner-outer double-layer setting device 100. The double-layer tentering setting device 200 provided with the inner-outer double-layer setting device 100 can achieve complex drying and setting of the two layers of textile fabric arranged in the upper and lower positions, and the vertical height of the double-layer tentering setting device 200 is reduced, so that the structure of the double-layer tentering setting device 200 is more compact, the occupation of space resources is reduced, and the double-layer tentering setting device 200 can provide hot gas to the first partitioned air chamber 111 and the second partitioned air chamber 112 through a group of hot air mechanisms 50, further reducing energy consumption, reducing the production cost and manufacturing cost of achieving complex drying and setting of the textile fabric, and overcoming the problems of large space occupation, high energy consumption and uneven heat distribution in the double outlet complex setting composed of two groups of setting machines arranged in the upper and lower positions and separated by a partition plate in the prior art. Moreover, by controlling the rotation speed of the first turbine 211 and the second turbine 221 driven by the plurality of first air supply units 21 and the plurality of second air supply units 22 in the first partitioned air chamber 111 and the second partitioned air chamber 112, respectively, the hot gas flow rate delivered to the first partitioned air chamber 111 and the second partitioned air chamber 112 is adjusted individually, so as to adjust the hot gas flow rate delivered to the outer air outlet pipe group 31 and the inner air outlet pipe group 32 individually, to accurately adjust the hot gas flow rate distributed by the outer air outlet pipe group 31 and the inner air outlet pipe group 32, to adaptively adjust the hot gas flow rate required by different types of textile fabric in different setting processes, and to ensure the drying and setting effect of the textile fabric.

[0080] Referring to Figure 15 As shown in the figure, the double-layer tentering setting device 200 comprises at least two inner-outer double-layer setting devices 100, and adjacent inner-outer double-layer setting devices 100 are longitudinally arranged along the shell 10 Figure 1Side wall splicing in the direction shown by the X-axis in the figure. The casings 10 of the two double-layer shaping devices 100 are isolated from each other, so that when the hot gas sucked by the air supply mechanism 20 into the air chamber 11 is sent into the first air outlet mechanism 30a and the second air outlet mechanism 30b, the hot gas in the two casings 10 will not interfere with each other, avoiding affecting the uniformity of the hot gas sent into the first air outlet mechanism 30a and the second air outlet mechanism 30b, and being beneficial to the heat being concentratedly radiated to the textile being subjected to stenter setting.

[0081] Refer Figure 11 As shown, the double-layer stenter setting equipment 200 further includes: fixed brackets 204 arranged on both sides of the air outlet mechanism along the longitudinal direction ( Figure 11 the direction shown by the X-axis in the figure). The first amplitude adjustment mechanism 202 includes: two first amplitude adjustment members 2021 arranged horizontally on the fixed brackets 204. The second amplitude adjustment mechanism 203 includes: two second amplitude adjustment members 2031 arranged horizontally on the fixed brackets 204; the two first amplitude adjustment members 2021 are used for stentering the textile when approaching each other, and the two second amplitude adjustment members 2031 are used for stentering the textile when approaching each other. By the two first amplitude adjustment members 2021 stentering the textile during the process of approaching and separating each other, and cooperating with the hot gas ejected from the air holes 3001 in the first air pipe group 301 and the second air pipe group 302 to heat the upper-layer textile, by the two second amplitude adjustment members 2031 stentering the textile during the process of approaching and separating each other, and cooperating with the hot gas ejected from the air holes 3001 in the third air pipe group 303 and the fourth air pipe group 304 to heat the lower-layer textile, so as to realize continuous and efficient stentering and setting treatment of the textile.

[0082] Refer Figure 12 As shown, the double-layer stenter setting equipment 200 further includes: a moisture discharge hole 2011 formed at the top of the box body 201, and a dehumidification pipe 205 connected to the moisture discharge hole 2011 and arranged at the top of the box body 201. Since the double-layer shaping device 100 will cause the temperature inside the box body 201 to continuously rise during operation, the moisture generated inside the box body 201 carries high heat, so it is necessary to discharge the moisture with high heat and mixed with oil fume and lint into the external air through the dehumidification pipe 205, and it is necessary to always keep the inside of the box body 201 in a negative pressure state to avoid the fire and explosion accidents caused by the accumulation of too much flammable gas in the box body 201. The aforementioned flammable gas refers to the gaseous mixture composed of organic vapor formed by benzene, biphenyl, methane, and aromatic hydrocarbon compounds generated by the textile during the stenter setting process at high temperature. The dehumidification pipe 205 can be configured as Figure 12 shown at the outer top of the box body 201. Multiple double-layer stenter setting equipment 200 form a double-layer stenter setting system 1000 and splice all the dehumidification pipes 205 along the horizontal direction ( Figure 13 the direction shown by the Y-axis in the figure) into an integral pipe 205', asFigure 13 As shown in Figure 14 Figure 206, the centrifugal fan 206 is disposed at the end of the overall pipeline 205', and under the action of the centrifugal fan 206, the moisture in the box body 201 is discharged into the external air; alternatively, the dehumidification pipeline 205 on the outer top of the box body 201 can be independently connected to a centrifugal fan 206 to discharge the moisture in the box body 201 into the external air under the action of the centrifugal fan 206, so as to keep the box body always in a negative pressure state.

[0083] Based on the technical solutions of any of the above double-width stenter setting devices 200 disclosed in the foregoing embodiments and their reasonable combinations, the present embodiment also discloses a double-width stenter setting system 1000.

[0084] Refer Figures 11 to 19 As shown in Figure 207, in the present embodiment, the double-width stenter setting system 1000 includes: a fabric feeding unit 300, at least one double-width stenter setting device 200 as disclosed in the embodiment, and a fabric discharging unit 500; the double-width stenter setting device 200 is disposed between the fabric feeding unit 300 and the fabric discharging unit 500. The textile fabric is fed into the double-width stenter setting device 200 through the fabric feeding unit 300 for drying, and during the drying process, the first amplitude adjusting mechanism 202 and the second amplitude adjusting mechanism 203 respectively perform amplitude setting on the two layers of textile fabrics arranged up and down. Finally, the textile fabric transmitted from the double-width stenter setting device 200 is arranged neatly by the fabric discharging unit 400 to complete the whole process. The fabric feeding unit 300 and the fabric discharging unit 400 are both prior arts, so they will not be described in detail herein. The double-width stenter setting system 1000 includes at least two double-width stenter setting devices 200, and two adjacent double-width stenter setting devices 200 are spliced along the side wall of the box body 201 in the longitudinal direction ( Figure 11 the direction shown by the X axis in Figure 208). The number of double-width stenter setting devices 200 can be 6 to 14 or even more.

[0085] When the textile enters the double-layer tentering setting device 200, the textile can be tentered and set in sequence through the double-layer tentering setting device 200, thereby improving the tentering and setting efficiency of the textile. The gradually increasing temperature inside the box 201 can be transferred to the adjacent box 201 due to the heat transfer performance of the steel plate (the box 201 is preferably made of steel plate material), thereby preheating the adjacent box 201 to improve the heat utilization rate. The double-layer tentering setting system 1000 of the embodiment includes the double-layer tentering setting device 200 which reduces the vertical height and volume, thereby reducing heat dispersion, enabling the heat of the hot gas generated by the burner to be concentrated in a relatively small space, further reducing energy consumption, and overcoming the problem of large energy consumption of the tentering and setting machine in the prior art, which leads to a large processing cost of the textile. The double-layer tentering setting system 1000 of the embodiment includes the double-layer tentering setting device 200 which controls the rotation speed of the first turbine 211 and the second turbine 221 driven by the plurality of first air supply units 21 and the plurality of second air supply units 22 in the first partitioned air chamber 111 and the second partitioned air chamber 112, respectively, to individually adjust the air volume of the hot gas delivered into the first partitioned air chamber 111 and the second partitioned air chamber 112, thereby realizing individual adjustment of the air volume of the hot gas delivered into the outer air outlet pipe group 31 and the inner air outlet pipe group 32, precisely adjusting the air volume of the hot gas sprayed by the outer air outlet pipe group 31 and the inner air outlet pipe group 32, and adjusting the air volume of the hot gas according to the requirements of different types of textile in different setting processes, to ensure the drying and setting effect of the textile.

Referring to Figure 13 With Figure 14 , the dehumidification pipeline 205 can be configured as the outer top of the box 201 as shown in Figure 12 , the dehumidification pipelines 205 of the plurality of double-layer tentering setting devices 200 can be connected end to end to form an integral pipeline 205', and the end of the integral pipeline 205' is configured with a centrifugal fan 206 to perform dehumidification under the action of the centrifugal fan 206; or, referring to Figure 16 With Figure 17As shown, the dehumidifying pipes 205 of multiple double-layer stenter setting devices 200 are all connected to a collecting and discharging pipe 207. A centrifugal fan 206 is arranged at the end of the collecting and discharging pipe 207, so as to draw the moisture in the box body 201 into the collecting and discharging pipe 207 through the dehumidifying pipe 205 under the action of the centrifugal fan 206, and then discharge the moisture in the box body 201 to the outside air through the collecting and discharging pipe 207.

[0087] Refer Figure 18 With Figure 19 As shown, exemplarily, in some embodiments, the air supply directions of the hot air mechanisms 50 in adjacent double-layer stenter setting devices 200 can also be configured to be periodically staggered. The air supply directions of the hot air mechanisms 50 in adjacent double-layer stenter setting devices 200 are staggered along Figure 18 the directions shown by arrow X1 and arrow X2 in the figure. The dehumidifying pipes 205 of multiple double-layer stenter setting devices 200 are all connected to a collecting and discharging pipe 207, so as to improve the uniformity of the temperature distribution in the double-layer stenter setting system 1000. < / /
