[0049] The present invention is described in detail below in conjunction with the various embodiments shown in the accompanying drawings, but it should be noted that these embodiments are not limitations of the present invention, and any equivalent transformations or substitutions in functions, methods, or structures made by ordinary technicians in the field based on these embodiments are all within the scope of protection of the present invention.

[0050] It is particularly important to note that in the following embodiments, the term "vertical" refers to Figure 1 The term "lateral" means Figure 4 The term "axial direction" means Figure 3 The term "longitudinal direction" refers to the direction of the axis P of the housing 1. Figure 4 In the direction indicated by the X-axis, the longitudinal direction is parallel to the axial direction.

[0051] Please refer to Figures 1 to 14 A specific implementation of a combined double-layer shaping device, double-layer stenter shaping equipment and system is disclosed.

[0052] Ginseng Figures 1 to 4 and Figure 8 As shown, in this embodiment, the combined double-layer shaping device 100 includes: a box body 1 with a hot air circulation chamber 10, a plurality of double-layer shaping machines 2 arranged in the box body 1 along the horizontal direction, and adjacent double-layer shaping machines 2 are staggered along the longitudinal direction thereof; the double-layer shaping machine 2 includes: a shell 20 which is surrounded by the box body 1 to form a wind chamber 21, a first air jet mechanism 22a and a second air jet mechanism 22b which are symmetrically arranged along the axis of the shell body 20 and connected to the ventilation chamber 21, a hot air supply mechanism 23 formed in the hot air circulation chamber 10 and connected to the ventilation chamber 21, the hot air supply mechanism 23 and the shell body 20 are formed on the same side of the box body 1, and an air supply mechanism 24 which transports hot gas to the first air jet mechanism 22a and the second air jet mechanism 22b. The hot air circulation chamber 10 provides hot gas to the wind chamber 21, and the hot gas in the wind chamber 21 is transported to the first air spray mechanism 22a and the second air spray mechanism 22b through the air supply mechanism 24. The hot gas is sprayed out through the first air spray mechanism 22a and the second air spray mechanism 22b, so that the hot gas acts evenly on the textile to quickly and evenly dry the textile.

[0053] The adjacent double-layer shaping machines 2 in the combined double-layer shaping device 100 are staggered along the longitudinal direction thereof, which can reduce the installation distance between the adjacent double-layer shaping machines 2, so that the multiple double-layer shaping machines 2 can fully utilize the lateral space of the box body 1. Compared with the double-outlet compound shaping device in the prior art, the hot air supply mechanism 23 and the shell 20 of the combined double-layer shaping device 100 are formed on the same side of the box body 1, which can reduce the distance between the first air spray mechanism 22a and the second air spray mechanism 22b, and reduce the vertical height of the double-layer shaping machine 2, thereby further reducing the overall vertical height of the combined double-layer shaping device 100, making the overall layout of the combined double-layer shaping device 100 more compact and orderly, and reducing the occupation of space resources. At the same time, the hot air circulation chamber 10 can collect and store the hot gas sprayed from the first air spray mechanism 22a and the second air spray mechanism 22b in each double-layer shaping machine 2, and is connected to the hot air circulation chamber 10 through the hot air supply mechanism 23, so that the hot gas in the hot air circulation chamber 10 can enter the hot air supply mechanism 23 and be heated again, so as to realize the recycling of the heated hot gas, improve the thermal efficiency of the combined double-layer shaping device 100, and reduce energy consumption.

[0054] Specifically, the housing 1 is provided with an even number of double-layer shaping machines 2 arranged in the transverse direction, and the hot air supply mechanism 23 is formed at one end of the adjacent double-layer shaping machines 2 opposite to the housing 20. By configuring an even number of double-layer shaping machines 2 arranged in the transverse direction, the symmetry of the overall layout of the combined double-layer shaping device 100 can be ensured, and the internal space of the housing 1 can be fully utilized. The hot air supply mechanism 23 is located at the ends of the first air spray mechanism 22a and the second air spray mechanism 22b included in the adjacent double-layer shaping machines 2, so that the hot air supply mechanism 23 can more efficiently collect the hot gas circulating in the hot air circulation chamber 10, heat the hot gas and then transport it to the air chamber 21 for distribution, thereby forming a hot air circulation in the hot air circulation chamber 10, improving the recycling rate of heat energy, and helping to maintain the stability of the hot gas temperature, ensuring the temperature control accuracy of the drying and shaping process of the combined double-layer shaping device 100. The shells 20 contained in adjacent double-layer setting machines 2 are isolated from each other, so that the hot gas sucked into the air chamber 21 by the air supply mechanism 24 will not interfere with each other when being sent to the first air jet mechanism 22a and the second air jet mechanism 22b, thereby avoiding affecting the uniformity of the hot gas being sent to the first air jet mechanism 22a and the second air jet mechanism 22b, and facilitating the concentrated emission of heat to the textile being stretched and set.

[0055] Specifically, the first air spray mechanism 22a includes: a first air spray pipe group 221 and a second air spray pipe group 222 arranged vertically up and down; the second air spray mechanism 22b includes: a third air spray pipe group 223 and a fourth air spray pipe group 224 arranged vertically up and down; the first air spray pipe group 221, the second air spray pipe group 222, the third air spray pipe group 223 and the fourth air spray pipe group 224 each include a plurality of air spray pipes (not marked) arranged horizontally, and a plurality of air spray holes 2220 are constructed on the inner side walls of the vertically opposite air spray pipes; the side walls of the shell 20 on which the first air spray mechanism 22a and the second air spray mechanism 22b are configured are constructed with an air guide port 201 for connecting the air supply mechanism 24 to the air spray pipes.

[0056] In this embodiment, preferably, Figures 1 to 7 As shown, the air supply mechanism 24 includes: at least two groups of air guide components 250 arranged side by side in the transverse direction and formed in the air chamber 21, and a fan unit 255 arranged on the side wall of the box body 1 to transport the hot gas in the air chamber 21 to the air guide component 250. The air chamber 21 provides hot gas to multiple air guide components 250 at the same time, and the number of fan units 255 is the same as that of the air guide components 250, and the multiple fan units 255 transport hot gas to the multiple air guide components 250 respectively.

[0057] Ginseng Figure 7 As shown, an air inlet duct 251 connected to the air chamber 21 is constructed on one side of the air guide component 250 facing the fan unit 255, and the air guide component 250 protrudes axially to form a partition 252 facing the air inlet duct 251, so as to separate the air guide component 250 into a first air guide duct 253 and a second air guide duct 254 respectively connected to the first air spray mechanism 22a and the second air spray mechanism 22b; the hot gas delivered to the air guide component 250 can be evenly and accurately divided through the partition 252, so that a part of the divided hot gas enters the first air guide duct 253, and the other part enters the second air guide duct 254, thereby realizing fine control and balanced distribution of the flow direction of the hot gas in the air guide component 250.

[0058] Ginseng Figure 7As shown, the fan unit 255 includes: a driving unit 256, a turbine 257 controlled by the driving unit 256 and formed on the air inlet pipe 251, the driving unit 256 drives the turbine 257 to rotate to transport the hot gas in the air chamber 21 to the air guide component 250, and the hot gas is transported to the first air injection mechanism 22a and the second air injection mechanism 22b through the first air guide pipe 253 and the second air guide pipe 254 in the air guide component 250. The side wall of the housing 20 of the box body 1 is recessed to form a support seat 258 extending into the air chamber 21, and the driving unit 256 is configured on the support seat 258. The driving shaft of the driving unit 256 passes through the support seat 258 and extends into the air chamber 21 to connect with the turbine 257. The rotation speed of the turbine 257 can be controlled by the driving unit 256. By adjusting the rotation speed of the turbine 257, the hot gas volume delivered to the first air jet mechanism 22a and the second air jet mechanism 22b can be adjusted; the high-speed rotation of the turbine 257 can provide a larger air volume output to the first air jet mechanism 22a and the second air jet mechanism 22b, whereas the low-speed rotation reduces the air volume of the first air jet mechanism 22a and the second air jet mechanism 22b. The rotation speed of the turbine 257 is dynamically controlled by the driving unit 256, so that the combined double-layer shaping device 100 can meet the drying and shaping requirements of different textiles.

[0059] Ginseng Figure 4 and Figure 5 As shown, the combined double-layer shaping device 100 drives the turbine 257 to rotate through the driving unit 256 to extract the hot gas in the air chamber 21 along the Figure 5 The hot gas is transported to the air guide component 250 through the air inlet pipe 251 in the direction indicated by the middle arrow f1. The air guide component 250 then distributes the hot gas accurately and evenly to the first air guide pipe 253 and the second air guide pipe 254 through the partition 252. The divided hot gas is respectively Figure 6 The directions indicated by the middle arrows f2 and f3 flow in the first air duct 253 and the second air duct 254 respectively, and finally reach the first air jet mechanism 22a and the second air jet mechanism 22b and are output from the first air jet mechanism 22a and the second air jet mechanism 22b. The hot gas will act evenly on the textile, achieving a quick and uniform drying effect on the textile.

[0060] Compared with the double-outlet compound shaping device in the prior art which controls the hot gas volume by manually adjusting the rotation angle of the air valve by the operator, the combined double-layer shaping device 100 adjusts the rotation speed of the turbine 257 through the fan unit 255 to adjust the hot gas volume delivered to the air guide component 250, thereby adjusting the hot gas volume delivered to the first air jet mechanism 22a and the second air jet mechanism 22b, so as to accurately adjust the hot gas volume sprayed by the first air jet mechanism 22a and the second air jet mechanism 22b, and adaptably adjust the hot gas volume required by different types of textiles in different shaping processes to ensure the drying and shaping effect of the textiles.

[0061] Ginseng Figure 6 and Figure 7 As shown, the partition 252 includes: a first partition 2521 and a second partition 2522 symmetrically arranged along the axis of the shell 20; the first partition 2521 and the second partition 2522 extend obliquely relative to the axis of the shell 20 and intersect each other; when the hot gas passes through the intersection of the first partition 2521 and the second partition 2522, the first partition 2521 and the second partition 2522 can effectively divide the hot gas, ensuring that the hot gas can be evenly distributed before being guided to the first air duct 253 and the second air duct 254, so that the hot gas can be more smoothly and evenly distributed along the first air duct 253 and the second air duct 254. Figure 7 The directions indicated by the middle arrows f2 and f3 are guided to the first air duct 253 and the second air duct 254 .

[0062] Ginseng Figure 7 As shown, the intersection of the first partition 2521 and the second partition 2522 is on the same axis P as the axis of the turbine 257. By aligning the intersection of the first partition 2521 and the second partition 2522 with the axis of the turbine 257, the distribution ratio of the hot gas can be better controlled to ensure that the hot gas output by the turbine 257 is minimally disturbed during separation, so that the hot gas separated by the first partition 2521 and the second partition 2522 can be more accurately and evenly distributed to the first air duct 253 and the second air duct 254; and the airflow generated by the rotation of the turbine 257 is aligned with the intersection of the first partition 2521 and the second partition 2522, thereby reducing the airflow turning and resistance, improving the efficiency and uniformity of the hot gas flow, and allowing the airflow generated by the turbine 257 to smoothly enter the separated first air duct 253 and the second air duct 254 along the axial direction.

[0063] Ginseng Figure 7As shown, the extension direction of the first partition plate 2521 and the extension direction of the second partition plate 2522 form an angle α greater than 0° and less than 180°. The side wall of the housing 20 configured with the first air jet mechanism 22a and the second air jet mechanism 22b is configured to form an air guide port 201 for the air guide component 250 to connect the first air jet mechanism 22a and the second air jet mechanism 22b, and the air guide component 250 transports hot gas to the first air jet mechanism 22a and the second air jet mechanism 22b through the air guide port 201. By adjusting the size of the angle α, the hot gas can be guided to enter the first air duct 253 and the second air duct 254 along a specific direction. When the angle α is large, the hot gas has a larger diffusion angle toward the first air duct 253 and the second air duct 254 after passing through the partition 252, which helps the hot gas to more widely cover the connection between the first air duct 253 and the first air jet mechanism 22a and the connection between the second air duct 254 and the second air jet mechanism 22b, so that the hot gas can enter each air duct 201 evenly; when the angle α is small, the hot gas has a smaller diffusion angle toward the first air duct 253 and the second air duct 254 after passing through the partition 252. The smaller angle α allows the airflow to enter each air duct 201 more concentratedly, which can reduce unnecessary airflow diffusion, reduce energy loss, and improve the transfer efficiency of heat energy.

[0064] Ginseng Figure 6 As shown, the first air duct 253 connects the first air jetting pipe group 221 and the second air jetting pipe group 222; the second air duct 254 connects the third air jetting pipe group 223 and the fourth air jetting pipe group 224. The first air duct 253 delivers hot gas to the first air jetting pipe group 221 and the second air jetting pipe group 222 through each air duct 201, and the first air jetting pipe group 221 and the second air jetting pipe group 222 then spray hot gas through the air spray hole 2220 to dry the textiles, and the second air duct 254 delivers hot gas to the third air jetting pipe group 223 and the fourth air jetting pipe group 224 through each air duct 201, and the third air jetting pipe group 223 and the fourth air jetting pipe group 224 then spray hot gas through the air spray hole 2220 to dry the textiles. The number of air jetting pipes connected to adjacent air guide components 250 is the same. The number of air jet pipes connected to each air guide component 250 is consistent to balance the hot air flow rate in the air outlet area of ​​the air jet pipe connected to each air guide component 250, so that the amount of hot air discharged from the air outlet area dominated by each adjacent air guide component 250 remains consistent, thereby achieving uniform heat distribution on the surface of the textile, avoiding shrinkage, deformation and other problems caused by local overheating or insufficient heating of the textile, thereby reducing the defective product rate and improving the overall product quality.

[0065] Ginseng Figure 1 and Figure 7As shown, the combined double-layer shaping device 100 also includes: a control system for controlling the speed of the fan unit 255 driving the turbine 257 to adjust the hot gas volume delivered to the air guide component 250, and uniformly adjust the hot gas volume delivered to the first air jet mechanism 22a and the second air jet mechanism 22b. The control system automatically adjusts the speed of the fan unit 255 driving the turbine 257 by monitoring and analyzing various parameters in the shaping process (such as textile type, processing stage, target temperature, etc.), ensuring that the hot gas volume delivered to the air guide component 250 can be timely adapted to the current processing requirements, improving the automation level and processing accuracy, and adapting and adjusting according to the hot gas volume required by different types of textiles in different shaping processes to ensure the drying and shaping effect of the textiles. By adjusting the rotation speed of the fan unit 255 driving the turbine 257, the control system can uniformly adjust the hot gas air volume supplied to the first air jet mechanism 22a and the second air jet mechanism 22b, and achieve a balance between the air volume of the first air jet mechanism 22a and the second air jet mechanism 22b, so as to ensure that the textile is evenly heated and reduce the weft skew and width unevenness during the drying and shaping process. Optionally, the aforementioned control system is a frequency converter for controlling the rotation of the fan unit 255 and a main control unit for controlling the frequency converter, and the main control unit can be a PLC, an industrial computer or a single-chip microcomputer, so as to control the rotation speed of the fan unit 255 driving the turbine 257 through the control system.

[0066] For example, in some embodiments, Figure 8 As shown, the air supply mechanism 24 includes: a plurality of wind transfer mechanisms 240 arranged in the horizontal direction and formed in the wind chamber 21, and a fan unit 241 arranged on the side wall of the box body 1 to transfer the hot gas in the wind chamber 21 to the wind transfer mechanism 240. Figures 9 to 11 As shown, the wind transfer mechanism 240 includes: a first air duct 242 and a second air duct 243 which are arranged in parallel along the vertical direction and respectively connect the first air jet mechanism 22a and the second air jet mechanism 22b, and a first air inlet duct 244 and a second air inlet duct 245 are respectively constructed on the side of the first air duct 242 and the second air duct 243 facing the fan unit 241; the fan unit 241 includes: a first driving unit 246 and a second driving unit 247, a first turbine 248 and a second turbine 249 which are respectively controlled by the first driving unit 246 and the second driving unit 247 and are respectively formed on the first air inlet duct 244 and the second air inlet duct 245, and the first driving unit 246 and the second driving unit 247 respectively drive the first turbine 248 and the second turbine 249 to rotate so as to transport the hot gas to the first air duct 242 and the second air duct 243 respectively, so as to independently adjust the air output of the first air jet mechanism 22a and the second air jet mechanism 22b. The side walls of the housing 20 of the box body 1 are respectively recessed to form a first support seat 2451 and a second support seat 2452 extending into the air chamber 21 . The first driving unit 246 and the second driving unit 247 are respectively disposed on the first support seat 2451 and the second support seat 2452 .

[0067] The rotation speeds of the first turbine 248 and the second turbine 249 can be controlled by the first drive unit 246 and the second drive unit 247, respectively. By adjusting the rotation speeds of the first turbine 248 and the second turbine 249, the hot gas volume delivered to the first air jet mechanism 22a and the second air jet mechanism 22b can be adjusted; the high-speed rotation of the first turbine 248 and the second turbine 249 can provide a larger air volume output to the first air jet mechanism 22a and the second air jet mechanism 22b, whereas the low-speed rotation reduces the air volume of the first air jet mechanism 22a and the second air jet mechanism 22b. The rotation speeds of the first turbine 248 and the second turbine 249 are dynamically controlled by the first drive unit 246 and the second drive unit 247, respectively, so that the combined double-layer shaping device 100 can adapt to the drying and shaping requirements of different textiles.

[0068] The combined double-layer shaping device 100 drives the first turbine 248 and the second turbine 249 to rotate respectively through the first driving unit 246 and the second driving unit 247 to extract the hot gas in the air chamber 21, so that the hot gas is respectively Fig. 9 The hot gas is transported to the first air duct 242 and the second air duct 243 through the first air inlet duct 244 and the second air inlet duct 245 in the direction indicated by the middle arrows f1 and f2. Fig.11 The air flows in the first air duct 242 and the second air duct 243 in the direction indicated by the middle arrows f3 and f4, and finally reaches the first air jet mechanism 22a and the second air jet mechanism 22b and is ejected from the first air jet mechanism 22a and the second air jet mechanism 22b to act on the textile surface.

[0069] Compared with the double-outlet compound shaping device in the prior art which controls the hot gas volume by manually adjusting the rotation angle of the air valve by the operator, the combined double-layer shaping device 100 can adjust the rotation speed of the first turbine 248 and the second turbine 249 to adjust the hot gas volume delivered to the first air duct 242 and the second air duct 243, thereby adjusting the hot gas volume delivered to the first air jet mechanism 22a and the second air jet mechanism 22b, so as to accurately adjust the hot gas volume sprayed by the first air jet mechanism 22a and the second air jet mechanism 22b, and adaptably adjust the hot gas volume required by different types of textiles in different shaping processes to ensure the drying and shaping effect of the textiles.

[0070] Ginseng Fig.11As shown, by adjusting the rotation speeds of the first driving unit 246 and the second driving unit 247 to drive the first turbine 248 and the second turbine 249 respectively, the control system can uniformly or separately adjust the hot gas volume supplied to the first air jet mechanism 22a and the second air jet mechanism 22b. The hot gas volume ejected by the first air jet mechanism 22a is greater than the hot gas volume ejected by the second air jet mechanism 22b, or the hot gas volume ejected by the first air jet mechanism 22a is equal to the hot gas volume ejected by the second air jet mechanism 22b, or the hot gas volume ejected by the first air jet mechanism 22a is less than the hot gas volume ejected by the second air jet mechanism 22b. By adjusting the hot gas volume of the first air jet mechanism 22a and the second air jet mechanism 22b, the supply intensity of the hot air can be flexibly adjusted according to the air volume requirements of different types of textiles. For example, for textiles that require more heat, the air volume output of the corresponding air jet mechanism (the first air jet mechanism 22a and / or the second air jet mechanism 22b) can be increased; when the textiles require less heat, the air volume output of the corresponding air jet mechanism (the first air jet mechanism 22a and / or the second air jet mechanism 22b) can be reduced, thereby ensuring the treatment effect and reducing energy waste. This allows the combined double-layer shaping device 100 to adapt to a wider range of textile types and treatment requirements.

[0071] Ginseng Figures 9 to 11 As shown, the first air duct 242 is connected to the first air jetting pipe group 221 and the second air jetting pipe group 222; the second air duct 243 is connected to the third air jetting pipe group 223 and the fourth air jetting pipe group 224. The first air duct 242 delivers hot gas to the first air jetting pipe group 221 and the second air jetting pipe group 222 through each air duct 201, and the first air jetting pipe group 221 and the second air jetting pipe group 222 then spray hot gas through the air spray hole 2220 to dry the textiles, and the second air duct 243 delivers hot gas to the third air jetting pipe group 223 and the fourth air jetting pipe group 224 through each air duct 201, and the third air jetting pipe group 223 and the fourth air jetting pipe group 224 then spray hot gas through the air spray hole 2220 to dry the textiles. By adjusting the rotational speed of the first turbine 248 and the second turbine 249 to control the amount of hot gas delivered to the first air duct 242 and the second air duct 243, the amount of hot gas delivered to the first spray pipe group 221, the second spray pipe group 222, the third spray pipe group 223 and the fourth spray pipe group 224 can be adjusted to adjust the amount of hot gas sprayed from the first spray pipe group 221, the second spray pipe group 222, the third spray pipe group 223 and the fourth spray pipe group 224, so as to adapt and adjust the amount of hot gas required by different types of textiles in different shaping processes to ensure the drying and shaping effect of the textiles.

[0072] Ginseng Figure 8 and Fig. 9As shown, the combined double-layer shaping device 100 also includes: a control system for controlling the fan unit 241 to drive the speed of the first turbine 248 and the second turbine 249 respectively. To adjust the hot gas volume delivered to the first air duct 242 and the second air duct 243. The control system automatically adjusts the speed of the first drive unit 246 and the second drive unit 247 to drive the first turbine 248 and the second turbine 249 respectively by monitoring and analyzing various parameters in the shaping process (such as textile type, processing stage, target temperature, etc.), ensuring that the hot gas volume delivered to the first air duct 242 and the second air duct 243 can be timely adapted to the current processing requirements, improving the automation level and processing accuracy, so as to adapt and adjust the hot gas volume required by different types of textiles in different shaping processes, and ensure the drying and shaping effect of the textiles. Optionally, the aforementioned control system is a frequency converter for controlling the rotation of the fan unit 241 and a main control unit for controlling the frequency converter, and the main control unit can be a PLC, an industrial computer or a single-chip microcomputer.

[0073] Ginseng Figures 3 to 5 As shown, the hot air supply mechanism 23 includes: a hot air pipe 230, which is composed of a combustion chamber 231 and a hot air chamber 232, and the hot air pipe 230 is connected to the shell 20 through the hot air chamber 232; a burner 234 is detachably provided at the bottom of the box body 1, and the nozzle of the burner 234 extends into the combustion chamber 231. The combustion chamber 231 is equipped with an air vent (not marked) for lateral air intake, and the air vent (not marked) is covered with a filter 233, which prevents dust and impurities from entering the combustion chamber 231. The burner 234 forms hot gas by burning gas (for example, natural gas) in the combustion chamber 231, and the hot gas is discharged along the combustion chamber 231. Figure 5 The hot gas in the hot gas chamber 232 is blown along the direction indicated by the middle arrow g2. Figure 5 The hot air is then transported into the air chamber 21 in the direction indicated by the middle arrow g3. Afterwards, the hot air ejected by the first air ejection mechanism 22a and the second air ejection mechanism 22b is recovered to the hot air circulation chamber 10 and flows along the Figure 5 The heat energy in the direction indicated by the middle arrow g1 enters the combustion chamber 231 through the vent hole and is heated again before being recycled, thereby increasing the reuse rate of heat energy and reducing energy consumption.

[0074] It should be noted that the combined double-layer shaping device 100 can be installed in Figure 3 The base 500 shown in the figure can support the combined double-layer shaping device 100 through the base 500 and provide an installation space for the burner 234. The combined double-layer shaping device 100 can also be installed on a supporting structure such as a frame (not shown), a steel structure platform (not shown), etc., as long as the combined double-layer shaping device 100 can be supported.

[0075] Based on the technical solution of a combined double-layer shaping device 100 disclosed in the aforementioned embodiment, this embodiment further discloses a double-layer stentering shaping device 200 .

[0076] Ginseng Fig.12 As shown, in this embodiment, the double-layer stentering and shaping device 200 includes: at least one combined double-layer shaping device 100 as disclosed in the above embodiment, a first stentering mechanism 202 arranged in the box 1 to stent the fabric dried by the first air jet mechanism 22a, and a second stentering mechanism 203 to stent the fabric dried by the second air jet mechanism 22b. The first stentering mechanism 202 is formed between the first air jet pipe group 221 and the second air jet pipe group 222, and the second stentering mechanism 203 is formed between the third air jet pipe group 223 and the fourth air jet pipe group 224. The first stentering mechanism 202 and the second stentering mechanism 203 are used to stent the two layers of textiles arranged up and down.

[0077] It should be noted that the box body 1 can be a supporting 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 combined double-layer shaping device 100. The double-layer tentering shaping device 200 equipped with the combined double-layer shaping device 100 can achieve double-layer drying and shaping of two layers of textiles arranged up and down. The hot air supply mechanism 23 and the shell 20 of the combined double-layer shaping device 100 are formed on the same side of the box body 1, which can reduce the distance between the first air jet mechanism 22a and the second air jet mechanism 22b, and reduce the vertical height of the double-layer shaping machine 2, thereby further reducing the vertical height of the combined double-layer shaping device 100 as a whole, making the overall layout of the combined double-layer shaping device 100 more compact and orderly.

[0078] Ginseng Fig.13 and Fig.14 As shown, the double-layer stentering and setting equipment 200 includes at least two combined double-layer setting devices 100, and adjacent combined double-layer setting devices 100 are spliced ​​along the longitudinal side wall of the box body 1. The hot air circulation chambers 10 included in each combined double-layer setting device 100 are connected, so that the hot gas sprayed by the first air spray mechanism 22a and the second air spray mechanism 22b in each double-layer setting machine 2 can be gathered inside the double-layer stentering and setting equipment 200, reducing heat dispersion, and facilitating each hot air supply mechanism 23 to more efficiently collect the hot gas circulating in the hot air circulation chamber 10, so as to heat the hot gas and then transport it to the air chamber 21 for distribution, thereby forming a hot air circulation in the hot air circulation chamber 10, improving the recycling rate of heat energy, and helping to maintain the stability of the hot gas temperature, ensuring the temperature control accuracy of the drying and setting process of the double-layer stentering and setting equipment 200.

[0079] Ginseng Fig.12As shown, the double-layer stretching and shaping equipment 200 also includes: a support frame 204 longitudinally arranged on both sides of the first air jet mechanism 22a and the second air jet mechanism 22b, the first stretching mechanism 202 includes: two first stretching members 2021 transversely arranged on the support frame 204, and the second stretching mechanism 203 includes: two second stretching members 2031 transversely arranged on the support frame 204; the two first stretching members 2021 are used to stretch the fabric when they are close to each other, and the two second stretching members 2031 are used to stretch the fabric when they are close to each other. The textile is stretched by the two first stretching members 2021 in the process of approaching and moving away from each other, and the upper textile is heated by the hot gas ejected from the air holes 2220 of the first air jet pipe group 221 and the second air jet pipe group 222. The textile is stretched by the two second stretching members 2031 in the process of approaching and moving away from each other, and the lower textile is heated by the hot gas ejected from the air holes 2220 of the third air jet pipe group 223 and the fourth air jet pipe group 224, so as to realize continuous and efficient stretching and shaping treatment of the textile.

[0080] Ginseng Figure 1 and Fig.12 As shown, the double-layer stentering and setting device 200 also includes: a dehumidification hole 2011 formed on the top of the box 1, and a dehumidification pipe 205 connected to the dehumidification hole 2011 and arranged on the top of the box 1. Since the combined double-layer setting device 100 will cause the temperature in the box 1 to continue to rise when working, the moisture generated in the box 1 is high in heat, so it is necessary to discharge the high-heat moisture mixed with oil smoke and lint into the outside air through the dehumidification pipe 205, and it is necessary to always keep the box 1 in a negative pressure state to avoid fire and explosion accidents caused by excessive accumulation of flammable gas in the box 1. The aforementioned flammable gas refers to a gaseous mixture composed of organic vapors formed by benzene, biphenyl, methane, and aromatic hydrocarbon compounds at high temperatures generated by textiles in the stentering and setting process.

[0081] Ginseng Figure 12 to Figure 14 As shown, the dehumidification pipe 205 of each double-layer stentering setting device 200 is connected to a drainage pipe 207, and the dehumidification fan 206 is arranged at the end of the drainage pipe 207, so that the moisture in the box body 1 is extracted into the drainage pipe 207 through the dehumidification pipe 205 under the action of the dehumidification fan 206, and then the moisture in the box body 1 is pumped into the outside air through the drainage pipe 207, so as to always keep the box body 1 in a negative pressure state. Alternatively, the dehumidification pipe 205 on the outer top of the box body 1 can also be independently connected to a dehumidification fan 206 (this state is not shown), so that the moisture in the box body 1 is pumped into the outside air under the action of the dehumidification fan 206, so as to always keep the box body 1 in a negative pressure state.

[0082] Based on the technical solution of the double-layer tentering and shaping device 200 disclosed in the above embodiment, this embodiment further discloses a double-layer tentering and shaping system 1000. The double-layer tentering and shaping system 1000 comprises: a cloth feeding unit 300, at least one double-layer tentering and shaping device 200 disclosed in the above embodiment, and a cloth discharging unit 400; the double-layer tentering and shaping device 200 is arranged between the cloth feeding unit 300 and the cloth discharging unit 400. The two layers of textiles arranged vertically up and down are arranged along the cloth feeding unit 300 and the cloth discharging unit 400. Fig.13 The direction indicated by the middle Y axis is sent into the double-layer stentering and shaping device 200 through the cloth feeding unit 300 for drying, and during the drying process, the two layers of textile arranged up and down are stretched and shaped respectively by the first stretching mechanism 202 and the second stretching mechanism 203. Finally, the textiles transmitted from the double-layer stentering and shaping device 200 are neatly arranged by the cloth discharging unit 400 to complete the whole process. The cloth feeding unit 300 and the cloth discharging unit 400 are both prior arts, so they are not described here. The double-layer stentering and shaping system 1000 includes at least two double-layer stentering and shaping devices 200, and the adjacent double-layer stentering and shaping devices 200 are arranged along the longitudinal direction of the box body 1 ( Fig.13 The side walls are spliced ​​in the direction indicated by the X-axis; the number of double-layer stentering and shaping devices 200 can be 3 to 7 or even more.

[0083] When the textile enters the double-layer stentering and setting device 200, it can be stentered and set in turn through the double-layer stentering and setting device 200, thereby improving the stentering and setting efficiency of the textile. The gradually rising temperature inside the box 1 will be transferred to the adjacent box 1 due to the heat transfer performance of the steel plate (the box 1 is preferably made of steel plate material), thereby preheating the adjacent box 1 to improve the heat utilization rate, and the double-layer stentering and setting device 200 included in the double-layer stentering and setting system 1000 of this embodiment reduces the vertical height and volume, thereby reducing heat dispersion, so that the heat of the hot gas generated by the burner 234 can be concentrated in a relatively small space, further reducing energy consumption, and overcoming the problem that the energy consumption of the stentering and setting machine in the prior art is large, resulting in a large processing cost of the textile.

[0084] Ginseng Fig.11 and Fig.12As shown, the dehumidification pipes 205 of the double-layer stenter setting device 200 included in the double-layer stenter setting system 1000 of this embodiment are all connected to a collection pipe 207, and the dehumidification fan 206 is arranged at the end of the collection pipe 207, so that the moisture in the box body 1 is extracted into the collection pipe 207 through the dehumidification pipe 205 under the action of the dehumidification fan 206, and then the moisture in the box body 1 is pumped into the outside air through the collection pipe 207, so as to always keep the box body 1 in a negative pressure state. Alternatively, the dehumidification pipe 205 on the outer top of the box body 1 can also be independently connected to a dehumidification fan 206 (this state is not shown), so that the moisture in the box body 1 is pumped into the outside air under the action of the dehumidification fan 206, so as to always keep the box body 1 in a negative pressure state.
