Description

Technical Field

[0001] This invention relates to the field of stenter technology, and in particular to a double-layer stenter device, a double-layer tenter frame device, system, and application. Background Technology

[0002] Tensoring, drying, and setting technology is the most widely used finishing technique in textile printing and dyeing. It is applicable to various types of fabrics, including woven fabrics, knitted fabrics, nonwovens, fur and leather, and composite fabrics. During chemical or physical processing methods such as dyeing and printing, fabrics are affected by various external forces, leading to problems such as radial elongation, weft shrinkage, uneven width, and weft skew, resulting in dimensional instability. These issues require stretching, drying, and setting to correct. Tensoring, drying, and setting involve controlling the width of cotton, silk, wool fabrics, and certain hygroscopic synthetic fibers containing a certain level of moisture in a tenter frame, drying them, eliminating internal stress, and adjusting the fabric's condition to ensure uniform width and dimensional stability.

[0003] Chinese invention patent CN110725090A discloses a double-layer stretching and setting device and system. In this prior art, it consists of two sets of setting machines arranged vertically and separated by a partition plate. Each set of setting machines generates heat through combustion by a burner. Under the action of a fan, the heat is transferred from the combustion chamber through the air chamber and the fixed shell to the upper and lower air outlet pipe groups. The upper and lower air outlet pipe groups spray hot air to stretch and set the textiles. The two sets of setting machines are stacked together to achieve the purpose of stretching and setting the two sets of textiles separately.

[0004] However, in order to adjust the amount of gas ejected from the air outlets of the upper and lower air outlet pipe groups in the aforementioned double-layer stretching and setting device, the operator needs to manually control the rotation angle of the adjusting air valve to control the amount of gas ejected from the air outlets of the upper and lower air outlet pipe groups. However, different types of fabrics require different air volumes in different setting processes (e.g., pre-setting, post-dyeing setting, finished product setting, etc.). The operator's manual control of the rotation angle of the adjusting air valve has low precision, making it difficult to accurately distribute the amount of hot gas ejected from the air outlets of the upper and lower air outlet pipe groups, thus affecting the drying and setting effect of the fabric.

[0005] In view of this, it is necessary to improve the existing double-layer tenter frame device and system to solve the above problems. Summary of the Invention

[0070] It should be noted that the objects processed by the hot gas conveyed by the double-layer setting device, double-layer stenter setting device, system and application disclosed in this embodiment include, but are not limited to, various fabrics such as warp knitting, weft knitting, chemical fiber fabrics, coatings, wool, cotton, polyester, and cloth, and are particularly suitable for woven fabrics or knitted fabrics. In each embodiment of this application, the textile fabric prepared from woven fabrics is used as an example for illustrative description and is applicable to other types of fabrics. Those skilled in the art can reasonably select the hot gas (for example, the hot gas generated by a burner) conveyed by the air supply mechanism, and determine specific parameters such as the air pressure, temperature, flow rate, and mixing ratio of the hot gas and air according to the different objects processed by the double-layer stenter setting device. At the same time, the heat sources for generating the foregoing hot gas include, but are not limited to, burners using natural gas as an energy source, or heat exchangers using heat-conducting oil or steam as a heat exchange medium.

[0071] Refer to Figures 1 to 9As shown, in this embodiment, the double-layer shaping device 100 includes: a housing 10 having an air chamber 11, a blowing mechanism 20 axially disposed in the housing 10, a first air outlet mechanism 30a and a second air outlet mechanism 30b symmetrically arranged along the axis P of the housing 10 and connected to the air chamber 11, and a partitioning mechanism 40 disposed inside the housing 10; the first air outlet mechanism 30a includes: a first air outlet pipe group 301 and a second air outlet pipe group 302 arranged vertically up and down; the second air outlet mechanism 30b includes: a third air outlet pipe group 303 and a fourth air outlet pipe group 304 arranged vertically up and down; the partitioning mechanism 40 divides the air chamber 11 into multiple sub-air chambers 110 and isolates adjacent sub-air chambers 110, and enables adjacent sub-air chambers 110 to be respectively connected to an upper air outlet pipe group 31 formed by the first air outlet pipe group 301 and the third air outlet pipe group 303 and a lower air outlet pipe group 32 formed by the second air outlet pipe group 302 and the fourth air outlet pipe group 304.

[0072] Specifically, the blowing mechanism 20 is disposed in the housing 10 along the axis P of the housing 10, the first air outlet mechanism 30a and the second air outlet mechanism 30b are symmetrically arranged along the axis P of the housing 10 and disposed in the housing 10, and both the first air outlet mechanism 30a and the second air outlet mechanism 30b are connected to the air chamber 11. The first air outlet pipe group 301 and the third air outlet pipe group 303 constitute the upper air outlet pipe group 31, the second air outlet pipe group 302 and the fourth air outlet pipe group 304 constitute the lower air outlet pipe group 32, and the upper air outlet pipe group 31 ejects hot gas downward along a vertical or approximately vertical direction (i.e., Figure 2 the direction indicated by arrow C in the figure), and the lower air outlet pipe group 32 ejects hot gas upward along a vertical or approximately vertical direction (i.e., Figure 2 the direction indicated by arrow C' in the figure), and the hot gas is uniformly ejected onto the fabric downward along the direction indicated by arrow C in the figure and upward along the direction indicated by arrow C' in the figure through the upper air outlet pipe group 31 and the lower air outlet pipe group 32 to perform convective heating on the fabric. The partitioning mechanism 40 is disposed in the air chamber 11, and the partitioning mechanism 40 is used to divide the air chamber 11 into multiple sub-air chambers 110 and isolate adjacent sub-air chambers 110, and enable adjacent sub-air chambers 110 to be respectively connected to the upper air outlet pipe group 31 and the lower air outlet pipe group 32.

[0073] Refer Figure 1 、<--0000188-->And Figure 9 ​​As shown, the air supply mechanism 20 includes: multiple fan units 21 arranged side-by-side in the transverse direction and independently configured in sub-air chambers 110; adjacent fan units 21 respectively transport hot gas to adjacent sub-air chambers 110, and individually adjust the airflow of the upper air outlet duct group 31 and the lower air outlet duct group 32. Multiple fan units 21 are arranged side-by-side in the transverse direction, the number of fan units 21 is the same as the number of sub-air chambers 110, and each sub-air chamber 110 is independently configured with one fan unit 21. Adjacent sub-air chambers 110 are respectively connected to the upper air outlet duct group 31 and the lower air outlet duct group 32. Hot gas is transported to the sub-air chamber 110 where the fan unit 21 is located through the fan unit 21, and further transported to the upper air outlet duct group 31 or the lower air outlet duct group 32 connected to that sub-air chamber 110. By individually controlling the speed of the fan unit 21 within the sub-air chamber 110, the volume of hot gas delivered to the sub-air chamber 110 can be individually adjusted. This allows for the individual adjustment of the volume of hot gas delivered to the upper exhaust pipe assembly 31 or the lower exhaust pipe assembly 32 connected to the sub-air chamber 110, thus enabling precise adjustment and distribution of the hot gas volume along the upper exhaust pipe assembly 31. Figure 2 The direction indicated by the middle arrow C is downward or along the lower exhaust pipe assembly 32. Figure 2 The upward flow of hot gas, indicated by the middle arrow C'.

[0074] For example, different types of textiles require different air volumes in different finishing processes (e.g., pre-setting, post-dyeing finishing, finished product finishing, etc.). For instance, different types of wet fabrics (i.e., fabrics with excess moisture) have different degrees of droop. During the drying process of different types of wet fabrics, the double-layer finishing device 100 needs to increase the rotational speed of the fan unit 21a used to deliver hot gas to the lower air outlet assembly 32 for wet fabrics with greater droop, in order to increase the air volume of hot gas delivered to the lower air outlet assembly 32, thereby increasing the air volume along the lower air outlet assembly 32. Figure 2 The upward flow of hot gas, as indicated by the middle arrow C', or the reduced speed of the fan unit 21b used to deliver hot gas to the upward exhaust duct assembly 31, can decrease the flow rate of the hot gas along the upper exhaust duct assembly 31. Figure 2 The hot gas flow rate ejected downwards in the direction indicated by the middle arrow C is such that the lower exhaust pipe assembly 32 is directed along... Figure 2 The upward-spraying hot gas volume, indicated by the middle arrow C', is greater than that of the upper exhaust pipe assembly 31 along... Figure 2 The hot gas flow rate ejected downwards in the direction indicated by the middle arrow C prevents the upper exhaust pipe assembly 31 from flowing downwards. Figure 2 Excessive downward airflow, as indicated by the middle arrow C, causes the wet fabric to sag excessively, which could negatively impact the drying effect.

[0075] Compared to existing double-layer stretching and setting devices where the operator manually controls the rotation angle of the air valve to regulate the hot gas flow, this double-layer setting device 100 regulates the hot gas flow delivered to the sub-air chamber 110 by independently controlling the speed of the fan unit 21. This allows for individual regulation of the hot gas flow delivered to the upper or lower air outlet pipe assembly 31 connected to the sub-air chamber 110, enabling precise adjustment and distribution of the hot gas flow along the upper air outlet pipe assembly 31. Figure 2 The direction indicated by the middle arrow C is downward or along the lower exhaust pipe assembly 32. Figure 2 The upward-spraying hot gas volume, indicated by the middle arrow C', is adjusted to adapt to the hot gas volume required by different types of textiles in different setting processes, ensuring the drying and setting effect of the textiles.

[0076] Preferably, the reference Figure 1 , Figure 2 and Figure 9 As shown, the double-layer shaping device 100 also includes: a control system (not shown) for controlling the rotational speed of the fan unit 21; the control system individually controls the rotational speed of the fan unit 21 in adjacent sub-cavities 110 to adjust the amount of hot gas delivered by the fan unit 21 to the corresponding sub-cavity 110, and individually adjusts the amount of hot gas delivered to the upper exhaust pipe group 31 or the lower exhaust pipe group 32. For example, by controlling the rotational speed of the fan unit 21a in sub-cavity 110a, the control system individually adjusts the amount of hot gas delivered to sub-cavity 110a, thereby achieving individual adjustment of the amount of hot gas delivered to the lower exhaust pipe group 32 connected to sub-cavity 110a; by controlling the rotational speed of the fan unit 21b in sub-cavity 110b, the control system individually adjusts the amount of hot gas delivered to sub-cavity 110b, thereby achieving individual adjustment of the amount of hot gas delivered to the upper exhaust pipe group 31 connected to sub-cavity 110b, so as to precisely adjust and distribute the amount of hot gas delivered to the upper exhaust pipe group 31 along... Figure 2 The direction indicated by the middle arrow C is downward and parallel to the lower exhaust pipe assembly 32. Figure 2 The upward-spraying hot gas volume, indicated by the central arrow C', is adjusted to adapt to the hot gas volume requirements of different types of textiles in different setting processes, ensuring the drying and setting effect of the textiles. Optionally, the aforementioned control system consists of a frequency converter for controlling the rotation of the fan unit 21 and a main control unit for controlling the frequency converter. The main control unit can be a PLC, an industrial computer, or a microcontroller, which controls the rotation speed of multiple fan units 21 through the control system and can individually control the rotation speed of the fan unit 21 in the sub-air chamber 110.

[0077] Exemplarily, the rotation speed of the fan unit 21 is controlled separately by a control system (not shown) so that the hot gas flow rate ejected from the upper air outlet pipe group 31 is greater than the hot gas flow rate ejected from the lower air outlet pipe group 32, or the hot gas flow rate ejected from the upper air outlet pipe group 31 is equal to the hot gas flow rate ejected from the lower air outlet pipe group 32, or the hot gas flow rate ejected from the upper air outlet pipe group 31 is less than the hot gas flow rate ejected from the lower air outlet pipe group 32. In actual use, the adjustment can be made according to the hot gas flow rate required for different types of textiles in different shaping processes.

[0078] Refer Figure 1 、 Figures 4 to 6 As shown, the housing 10 is configured to have a first sub-tube group 121 and a third sub-tube group 123 that are respectively connected to the first air outlet pipe group 301 and the third air outlet pipe group 303, a second sub-tube group 122 and a fourth sub-tube group 124 that are respectively connected to the second air outlet pipe group 302 and the fourth air outlet pipe group 304, a first bending portion 131 that separates the first sub-tube group 121 and the second sub-tube group 122, a second bending portion 132 that separates the third sub-tube group 123 and the fourth sub-tube group 124, and a third bending portion 133 that separates the second sub-tube group 122 and the third sub-tube group 123. In adjacent sub-air chambers 110, one sub-air chamber 110 communicates with the first sub-tube group 121 and the third sub-tube group 123, and respectively communicates with the first air outlet pipe group 301 and the third air outlet pipe group 303 through the first sub-tube group 121 and the third sub-tube group 123, so that the fan unit 21 in this sub-air chamber 110 transports hot gas to the first air outlet pipe group 301 and the third air outlet pipe group 303 respectively through the first sub-tube group 121 and the third sub-tube group 123. The other sub-air chamber 110 communicates with the second sub-tube group 122 and the fourth sub-tube group 124, and respectively communicates with the second air outlet pipe group 302 and the fourth air outlet pipe group 304 through the second sub-tube group 122 and the fourth sub-tube group 124, so that the fan unit 21 in this sub-air chamber 110 transports hot gas to the second air outlet pipe group 302 and the fourth air outlet pipe group 304 respectively through the second sub-tube group 122 and the fourth sub-tube group 124, thereby realizing the transportation of hot gas to the upper air outlet pipe group 31 and the lower air outlet pipe group 32 respectively.

[0079] Refer Figure 1 And Figure 2 、 Figures 5 to 9As shown in the figure, the separation mechanism 40 includes: a plurality of first separation parts 43 and second separation parts 44 alternately arranged in sequence along the transverse direction between the first bending part 131 and the second bending part 132; a connecting separation part 45 that abuts against the third bending part 133 and connects adjacent first separation parts 43 and second separation parts 44.

[0081] Specifically, refer to Figure 2 , Figure 5 and Figure 7 As shown, the first sub-pipe group 121 and the second sub-pipe group 122 are isolated by the first partition 43 and the second distribution pipe 462. The first air chamber 111 is connected to the second sub-pipe group 122 through the first notch 451. The third sub-pipe group 123 and the fourth sub-pipe group 124 are isolated by the second partition 44 and the first distribution pipe 461, and the first air chamber 111 is connected to the fourth sub-pipe group 124. Thus, the first air chamber 111 is connected to the second air outlet pipe group 302 and the fourth air outlet pipe group 304 through the second sub-pipe group 122 and the fourth air outlet pipe group 124, respectively. The first air chamber 111 is supplied with hot gas by the fan unit 21 inside it, and the hot gas is directed along the... Figure 2 (or Figure 5 Arrows D2 and D4 indicate that the hot gas is conveyed to the second sub-tube group 122 and the fourth sub-tube group 124 respectively, so that the hot gas can be further conveyed along the second sub-tube group 122 and the fourth sub-tube group 124. Figure 2 The airflow is directed in the directions indicated by the middle arrows D21 and D41 to the second exhaust pipe group 302 and the fourth exhaust pipe group 304, respectively. By individually controlling the speed of the fan unit 21 in the first air chamber 111, the airflow of the hot gas delivered to the first air chamber 111 can be individually adjusted, thereby achieving individual adjustment of the airflow of the hot gas delivered to the second exhaust pipe group 302 and the fourth exhaust pipe group 304, and thus adjusting the airflow of the second exhaust pipe group 302 and the fourth exhaust pipe group 304 along the direction indicated by the middle arrows D21 and D41. Figure 2The air volume of the hot gas ejected upward in the direction indicated by the arrow C' can be adaptively adjusted according to the air volume of the hot gas required for different types of textiles in different shaping processes, so as to ensure the drying and shaping effect of the textiles.

[0082] Specifically, referring Figure 2 、 Figure 6 to Figure 8 as shown, the third sub-tube group 123 and the fourth sub-tube group 124 are isolated by the second partition 44 and the first distribution pipe 461. The second air chamber 112 is connected to the third sub-tube group 123 through the second notch 452. The first sub-tube group 121 and the second sub-tube group 122 are isolated by the first partition 43 and the second distribution pipe 462, and the second air chamber 112 is connected to the first sub-tube group 121, so that the second air chamber 112 is respectively connected to the first air outlet pipe group 301 and the third air outlet pipe group 303 through the first sub-tube group 121 and the third sub-tube group 123; the second air chamber 112 transports the hot gas to the second air chamber 112 through the fan unit 21 inside it, and transports the hot gas along Figure 2 (or Figure 6 ) in the directions indicated by the arrows D1 and D3 to the first sub-tube group 121 and the third sub-tube group 123 respectively, so as to further transport the hot gas along Figure 2 in the directions indicated by the arrows D11 and D31 to the first air outlet pipe group 301 and the third air outlet pipe group 303 respectively through the first sub-tube group 121 and the third sub-tube group 123. By independently controlling the rotation speed of the fan unit 21 in the second air chamber 112, the air volume of the hot gas transported into the second air chamber 112 can be independently adjusted, so as to independently adjust the air volume of the hot gas transported to the first air outlet pipe group 301 and the third air outlet pipe group 303, and accurately adjust and distribute the air volume of the hot gas ejected downward in the direction indicated by the arrow C along Figure 2 to adaptively adjust according to the air volume required for different types of textiles in different shaping processes, so as to ensure the drying and shaping effect of the textiles.

[0083] Referring Figure 1 to <\ Figure 16As shown, the double-layer shaping device 100 further includes: a hot air mechanism 50 formed axially between the first air outlet mechanism 30a and the second air outlet mechanism 30b and connecting the air chamber 11; the hot air mechanism 50 includes: a combustion chamber 51, a heating source for forming hot gas in the combustion chamber 51, and a hot air duct 52 connecting the combustion chamber 51 and the housing 10. The combustion chamber 51 is configured with ventilation holes (not labeled) for laterally sucking air, and the ventilation holes (not labeled) are covered with a filter net 53. Preferably, the heating source is configured as a burner 54 detachably provided on the side wall of the combustion chamber 51, and the nozzle (not shown) of the burner 54 extends into the combustion chamber 51. The burner 54 forms hot gas in the combustion chamber 51 by burning gas (such as natural gas). Under the action of the fan unit 21, the hot gas is transported from the combustion chamber 51 through the hot air duct 52 to the sub-air chamber 110 and further transported to the first air outlet mechanism 30a and the second air outlet mechanism 30b, so that the first air outlet mechanism 30a and the second air outlet mechanism 30b eject hot gas to dry and shape the fabric.

[0084] Refer Figure 1 、 Figure 11 And Figure 12 As shown, the hot air duct 52 is configured with a plurality of hot air distribution pipes 521 connecting the sub-air chamber 110, or the hot air duct 52 is configured with a plurality of hot air distribution ports 522 connecting the sub-air chamber 110. As Figure 11 shown, the hot air duct 52 can be configured with hot air distribution pipes 521 for transporting hot gas to the sub-air chamber 110. The number of hot air distribution pipes 521 is the same as the number of fan units 21. The fan units 21 suck the hot gas in the hot air duct 52 and transport it into the corresponding sub-air chamber 110. As Figure 12As shown, the hot air duct 52 can also be configured with a hot air distribution port 1422 for delivering hot air to the sub-air chamber 110. The number of hot air distribution ports 1422 is the same as the number of fan units 21. The fan units 21 suck the hot air in the hot air duct 52 through the hot air distribution ports 1422 and deliver it into the corresponding sub-air chambers 110. A set of hot air mechanisms 50 generates hot air, and the hot air is delivered to multiple sub-air chambers 110 simultaneously through the hot air duct 52. Then, the fan units 21 in each sub-air chamber 110 deliver the hot air in the hot air duct 52 to the first air outlet mechanism 30a and the second air outlet mechanism 30b respectively, so that the first air outlet mechanism 30a and the second air outlet mechanism 30b can simultaneously perform double-layer drying and shaping on two layers of textiles. Compared with the prior art double-layer stenter setting device composed of two stenter setting machines arranged vertically and separated by a partition board, the overall vertical height of this double-layer setting device 100 is reduced, making the structure of the double-layer setting device 100 more compact, reducing the occupation of space resources. Moreover, the double-layer setting device 100 can provide hot air to multiple sub-air chambers 110 through a set of hot air mechanisms 50, further reducing energy consumption and the cost of double-layer drying and shaping of textiles, and overcoming the problems of large space occupation and high energy consumption existing in the double-layer stenter setting device composed of two stenter setting machines arranged vertically and separated by a partition board in the prior art.

[0085] As shown Figures 1 to 6 As shown, the fan unit 21 includes: a turbine 213 formed in the sub-air chamber 110, a driving unit 212 disposed on the outer wall of the housing 10 opposite to the hot air mechanism 50, a driving shaft of the driving unit 212 passing through the side wall of the housing 10 and extending into the sub-air chamber 110 to connect to the turbine 213, and an air guiding cylinder 214 formed in the sub-air chamber 110 and isolated from the sub-air chamber 110 and passing through the third bending portion 133. The air guiding cylinder 214 is connected to the hot air distribution pipe 521 or the hot air distribution port 522 to guide the hot air to the turbine 213. A sealing plate 211 is disposed on the side wall of the housing 10 and is used to support and fix the driving unit 212 and seal the connection between the driving unit 212 and the housing 10 to prevent the hot air in the sub-air chamber 110 from leaking. The driving unit 212 drives the turbine 213 to rotate to guide the hot air in the hot air duct 52 to the turbine 213 through the air guiding cylinder 214, and the hot air is further sucked into the sub-air chamber 110 through the turbine 213. The rotation speed of the turbine 213 driven by the driving unit 212 is controlled by a control system (not shown), so as to control the air volume of the hot air sucked into the sub-air chamber 110 by the turbine 213, and to achieve independent adjustment of the air volume of the hot air delivered to the upper air outlet pipe group 31 or the lower air outlet pipe group 32.

[0086] Optionally, the fan unit 21 may be configured as a centrifugal fan, and the drive unit 212 may be configured as a three-phase AC motor. The three-phase AC motor is independently regulated in speed by a control system (not shown) to control the rotational speed of the turbine 213, thereby controlling the amount of hot gas in the conveying sub-air chamber 110. It should be noted that the turbine 213 may be components such as an impeller or blades, as long as it can achieve sucking the hot gas into the sub-air chamber 110.

[0087] Refer Figure 2 、 Figure 5 and Figure 6 and Figure 9 As shown, the air chamber 11 includes: a second air duct 1132 and a fourth air duct 1134 for the hot gas in the first air chamber 111 to flow to the second sub-tube group 122 and the fourth sub-tube group 124 respectively, and a first air duct 1131 and a third air duct 1133 for the hot gas in the second air chamber 112 to flow to the first sub-tube group 121 and the third sub-tube group 123 respectively. Specifically, refer Figure 2 and Figure 5 and Figure 10 As shown, the fan unit 21 in the first air chamber 111 sucks the hot gas in the hot air duct 52 and transports the hot gas into the guide air duct 231 in the first air chamber 111. During the process that the hot gas flows in a swirling direction in the guide air duct 231, the two side plates 233 can divide the swirling hot gas in the guide air duct 231 into two hot gas flows, and cooperate with the air guide plate 232 to guide the two hot gas flows in two opposite directions ( Figure 2 the directions shown by arrow D2 and arrow D in Figure 2 and send them into the second air duct 1132 and the fourth air duct 1134 respectively through the air outlet 2311, and then transport the hot gas into the second sub-tube group 122 and the fourth sub-tube group 124 through the second air duct 1132 and the fourth air duct 1134 respectively, so as to realize transporting the hot gas to the second outlet pipe group 302 and the fourth outlet pipe group 304. The second outlet pipe group 302 and the fourth outlet pipe group 304 then spray the hot gas upward along the Figure 2 direction shown by arrow C' in

[0088] Refer Figure 2 and Figure 6 and Figure 10As shown, the fan unit 21 in the second air chamber 112 draws hot gas from the hot air duct 52 and transports the hot gas into the air guide duct 231 in the second air chamber 112. During the swirling flow of the hot gas within the air guide duct 231, the two sets of side plates 233 divide the swirling hot gas flow into two streams, which, in conjunction with the air guide plate 232, guide the two streams of hot gas in two opposite directions. Figure 2 (As indicated by arrows D1 and D3) and through air outlets 2311, the hot gas is fed into the first air duct 1131 and the third air duct 1133 respectively. The hot gas is then transported through the first air duct 1131 and the third air duct 1133 to the first sub-pipe group 121 and the third sub-pipe group 123 respectively, thus delivering hot gas to the first exhaust pipe group 301 and the third exhaust pipe group 303. The first exhaust pipe group 301 and the third exhaust pipe group 303 then pass through the exhaust port 3001 along... Figure 2 Hot gas is ejected downwards in the direction indicated by arrow C to dry the textiles. By individually controlling the rotational speed of the fan unit 21 within the second air chamber 112, the airflow of hot gas delivered to the second air chamber 112 is controlled. This allows for individual adjustment of the airflow to the first and third air outlet pipe groups 301 and 303, enabling precise regulation and distribution of the hot gas flow along the first and third air outlet pipe groups 301 and 303. Figure 2 The volume of hot gas ejected downwards in the direction indicated by the middle arrow C is adjusted to adapt to the hot gas volume required by different types of textiles in different setting processes, ensuring the drying and setting effect of the textiles.

[0089] Exemplary, in some embodiments, the reference Figure 2 and Figure 10 As shown, the fan unit 21 further includes: a guide member 23 symmetrically arranged within the sub-air chamber 110 along the axis L of the turbine 213 and formed around the turbine 213. The guide member 23 divides the sub-air chamber 110 to form an air duct 231, and the air duct 231 forms two air outlets 2311 with opposite outlet directions in the vertical direction. The drive unit 212 drives the turbine 213 to rotate, drawing hot gas into the first air chamber 111 and causing the hot gas to flow in a swirling direction within the air duct 231. The guide member 23 divides the swirling hot gas within the air duct 231 into two streams of hot gas, which are guided by the guide member 23 to flow vertically and with opposite outlet directions (along the axis L). Figure 2Two air supply openings 2311 (in the directions indicated by arrows D2 and D4) respectively send hot air into the second air duct 1132 and the fourth air duct 1134, and then the hot air is respectively transported to the second sub-tube group 122 and the fourth sub-tube group 124 through the second air duct 1132 and the fourth air duct 1134; the driving unit 212 drives the turbine 213 to rotate to suck the hot air into the second air chamber 112, and makes the hot air flow in a swirling direction in the air guiding duct 231. The air guiding member 23 divides the hot air flowing in a swirling direction in the air guiding duct 231 into two hot air streams, and the air guiding member 23 guides the two hot air streams to respectively flow vertically and in opposite outlet directions (along Figure 2 Two air supply openings 2311 (in the directions indicated by arrows D1 and D3) respectively send hot air into the first air duct 1131 and the third air duct 1133, and then the hot air is respectively transported to the first sub-tube group 121 and the third sub-tube group 123 through the first air duct 1131 and the third air duct 1133. A set of hot air mechanism 50 generates hot air, and then the hot air generated by the hot air mechanism 50 is respectively sent into the first air outlet mechanism 30a and the second air outlet mechanism 30b through the air supply mechanism 20, so that the first air outlet mechanism 30a and the second air outlet mechanism 30b can simultaneously perform double-layer drying and shaping on two layers of textiles respectively. Compared with the double-layer stenter setting device composed of two stenter setting machines arranged up and down and separated by a partition plate in the prior art, the overall vertical height of this double-layer setting device 100 is reduced, so that the structure of the double-layer setting device 100 is more compact, reducing the occupation of space resources. And this double-layer setting device 100 can provide hot air for multiple sub-air chambers 110 through a set of hot air mechanism 50, further reducing energy consumption and reducing the cost of double-layer drying and shaping of textiles, overcoming the problems of large space occupation and high energy consumption existing in the double-layer stenter setting device composed of two stenter setting machines arranged up and down and separated by a partition plate in the prior art.

[0090] Refer Figure 2 to Figure 10 As shown, the air guiding member 23 includes: a wind guiding plate 232 that extends obliquely with respect to the axis P of the housing 10, and a side plate 233 constructed at the extending end of the wind guiding plate 232 and extending away from the axis P of the housing 10; the fan unit 21 sucks the hot air in the hot air mechanism 50 and sucks the hot air into the air guiding duct 231, so that during the process of the hot air flowing in a swirling direction in the air guiding duct 231, the two side plates 233 can divide the hot air flowing in a swirling direction in the air guiding duct 231 into two hot air streams, and cooperate with the wind guiding plate 232 to guide the two hot air streams to respectively flow in two opposite directions (for example, along Figure 2 the directions indicated by arrows D1 and D3) and are respectively sent into the first sub-tube group 121 and the third sub-tube group 123 through the air supply openings 2311.

[0091] Refer Figure 9 to Figure 10As shown, the guide members 23 in adjacent sub-chambers 110 are arranged vertically in a mirror image relative to the connecting partition 45. When there are multiple sub-chambers 110, the guide member 23 in one sub-chamber 110 divides the hot gas flowing in a swirling direction in the air duct 231 into two streams of hot gas. The guide member 23 guides the two streams of hot gas vertically and in opposite outlet directions (along...). Figure 2 The two air outlets 2311 (in the directions indicated by arrows D1 and D3) respectively supply air into the first air duct 1131 and the third air duct 1133, while the guide member 23 in the sub-air chamber 110 adjacent to the aforementioned sub-air chamber 110 guides the hot gas vertically and in the opposite direction to the outlet (e.g., along the direction indicated by arrows D1 and D3). Figure 2 The two air outlets 2311 (in the directions indicated by arrows D2 and D4) respectively supply air into the second air duct 1132 and the fourth air duct 1134, so that the hot air transported by multiple sub-air chambers 110 to the first air duct 1131 will enter the first sub-pipe group 121 through the first air duct 1131, and be evenly distributed into the multiple first air outlet pipes 3011 included in the first air outlet pipe group 301 through the multiple air guides 1201 included in the first sub-pipe group 121, so as to facilitate the hot air supplied to the first air duct 1131. The gas can be evenly delivered to multiple first air outlets 3011, so that the hot gas is concentrated and sprayed onto the textile being stretched and set. At the same time, the hot gas delivered to the second air duct 1132, the third air duct 1133 and the fourth air duct 1134 by the other multiple sub-air chambers 110 can also be evenly delivered to the second air outlet 3021, the third air outlet 3031 and the fourth air outlet 3041 respectively, and the principle and beneficial effect are the same as those of the gas delivered to the first air outlet 3011, which will not be repeated here.

[0092] It should be noted that, in this embodiment, preferably, the reference... Figure 2 and Figure 9 As shown, the first dividing portion 43 is laterally disposed on the first bending portion 131, and the second dividing portion 44 is laterally disposed on the second bending portion 132. In some embodiments, the first dividing portion 43 may also be obliquely disposed on the first bending portion 131. Figure 13 The first dividing portion 43', shown by the dashed line, is inclined. The second dividing portion 44 can also be inclinedly arranged on the second bent portion 132. (Refer to...) Figure 13 The inclined second partition 44' shown by the dashed line can be used as long as it can isolate the adjacent sub-chamber 110 and allow the hot gas in the adjacent sub-chamber 110 to be transported to the corresponding connected upper exhaust pipe group 31 and lower exhaust pipe group 32.

[0093] It should be noted that in some embodiments, the references Figure 13 As shown, the first partition 43 and the second partition 44 are offset laterally and spaced apart, or, see... Figure 14As shown, the first partition part 43 and the second partition part 44 are arranged in a staggered manner along the transverse direction; the above two distribution methods of the first partition part 43 and the second partition part 44 in the housing 10 (that is, the first partition part 43 and the second partition part 44 are arranged offset and spaced along the transverse direction, and the first partition part 43 and the second partition part 44 are arranged in a staggered manner along the transverse part) will cause the connecting partition part 45 to tilt, and the position of the guiding member 23 arranged on the connecting partition part 45 will change with the tilt of the connecting partition part 45, thereby increasing the occupancy of the connecting partition part 45 and the guiding member 23 in the internal space of the housing 10. Therefore, in this embodiment, preferably, the connecting partition part 45 is arranged vertically and connects the adjacent ends of the first partition part 43 and the second partition part 44 that are close to each other, so as to reduce the occupancy of the connecting partition part 45 and the guiding member 23 in the internal space of the housing 10.

[0094] Refer to Figure 10 As shown, the extension direction formed by the air deflector 232 and the extension direction formed by the side plate 233 form an included angle α that is tangent to the swirling flow direction of the hot gas in the air duct 231. The included angle α is greater than 0° and less than 180°. It should be noted that the side plate 233 can also be set as a linear plate body (not shown) or an arc-shaped plate body as shown in Figure 10 shown. The air deflector 232 can also be set as a linear plate body or an arc-shaped plate body as shown in Figure 10 shown (not shown), as long as it can guide the two hot gases to be sent out along two opposite vertical directions respectively. In this embodiment, the air deflector 232 is preferably a linear plate body as shown in Figure 10 shown, and the side plate 233 is preferably an arc-shaped plate body as shown in Figure 10 shown. The included angle α is formed by the extension direction of the air deflector 232 configured as a linear plate body and the tangent Q of the side plate 233 configured as an arc-shaped plate body. When the position of the side plate 233 remains unchanged and the included angle α is smaller, the distance between the air deflector 232 and the fan unit 21 is larger, and the space of the air duct 231 formed by the air deflector 232 is also larger, resulting in an increase in the air flow rate of the hot gas that the air duct 231 can accommodate, thereby increasing the air flow rate of the hot gas sent into the first air outlet mechanism 30a and the second air outlet mechanism 30b, so as to improve the drying and shaping effect and drying efficiency of the textile. In actual use, the air flow rate of the hot gas that the air duct 231 can accommodate and the air flow rate of the separated hot gas can be adjusted by setting the angle of the included angle α.

[0095] Refer to Figure 4 and Figure 15As shown, the first air outlet pipe group 301, the second air outlet pipe group 302, the third air outlet pipe group 303 and the fourth air outlet pipe group 304 all include a plurality of air outlet pipes arranged horizontally. A plurality of air outlet holes 3001 for air outlet are formed on the inner side walls of the air outlet pipes opposite to each other vertically; The air outlet pipes include: a plurality of first air outlet pipes 3011 constituting the first air outlet pipe group 301, a plurality of second air outlet pipes 3021 constituting the second air outlet pipe group 302, a plurality of third air outlet pipes 3031 constituting the third air outlet pipe group 303, and a plurality of fourth air outlet pipes 3041 constituting the fourth air outlet pipe group 304; A plurality of air outlet holes 3001 for jetting hot gas are formed on the inner side walls of the first air outlet pipe 3011 and the second air outlet pipe 3021 opposite to each other vertically, and a plurality of air outlet holes 3001 for jetting hot gas are formed on the inner side walls of the third air outlet pipe 3031 and the fourth air outlet pipe 3041 opposite to each other vertically. The first sub-pipe group 121, the second sub-pipe group 122, the third sub-pipe group 123 and the fourth sub-pipe group 124 all include a plurality of air guiding openings 1201 respectively corresponding to and communicating with the air outlet pipes, and the air outlet pipes and the air guiding openings 1201 form a detachable connection.

[0096] Specifically, the first sub-pipe group 121 and the second sub-pipe group 122 can be detachably connected to the first air outlet pipe group 301 and the second air outlet pipe group 302 respectively by means of snap connection, and the third sub-pipe group 123 and the fourth sub-pipe group 124 can be detachably connected to the third air outlet pipe group 303 and the fourth air outlet pipe group 304 respectively by means of snap connection, or can also be detachably connected by other means (such as the connection method of bolt assemblies), and no examples are given here one by one. It can be understood that by detachably connecting the first sub-pipe group 121 and the second sub-pipe group 122 to the first air outlet pipe group 301 and the second air outlet pipe group 302 respectively, and the third sub-pipe group 123 and the fourth sub-pipe group 124 to the third air outlet pipe group 303 and the fourth air outlet pipe group 304 respectively, it is convenient to disassemble, install, replace and clean the first air outlet mechanism 30a and the second air outlet mechanism 30b respectively, so as to facilitate the maintenance personnel to detect or repair the first air outlet mechanism 30a and the second air outlet mechanism 30b.

[0097] Based on the technical solution of a double-layer shaping device 100 disclosed in the foregoing embodiment, the present embodiment also discloses a double-layer stenter 200.

[0098] See Figure 16As shown, in this embodiment, the double-layer stenter 200 includes: a box body 201, at least one double-layer setting device 100 axially arranged in the box body 201 as disclosed in the above embodiment, a first amplitude adjustment mechanism 202 disposed inside the box body 201 and formed between the first air outlet pipe group 301 and the second air outlet pipe group 302 for stretching the textile, and a second amplitude adjustment mechanism 203 disposed inside the box body 201 and formed between the third air outlet pipe group 303 and the fourth air outlet pipe group 304 for stretching the textile. The upper and lower arranged two layers of textiles are stretched by the first amplitude adjustment mechanism 202 and the second amplitude adjustment mechanism 203 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 amplitude adjustment mechanism 202, the second amplitude adjustment mechanism 203 and the double-layer setting device 100. The double-layer stenter 200 equipped with the double-layer setting device 100 can perform compound drying and setting on the upper and lower arranged two layers of textiles, and reduces the vertical height of the double-layer stenter 200, so that the structure of the double-layer stenter 200 is more compact, reduces the occupation of space resources, and the double-layer stenter 200 can provide hot gas for multiple sub-air chambers 110 through a group of hot air mechanisms 50, further reducing energy consumption, reducing the production cost and manufacturing cost of compound drying and setting of textiles, and overcoming the problems existing in the double-export compound setting composed of two setting machines arranged up and down and separated by a partition board in the prior art, such as large space occupation, high energy consumption and uneven heat distribution inside a single double-layer stenter due to the partition board arranged in the double-layer setting device in the prior art. And, by independently controlling the rotation speed of the fan unit 21 to adjust the air volume of the hot gas delivered into the sub-air chamber 110, thereby independently adjusting the air volume of the hot gas delivered to the upper air outlet pipe group 31 and the lower air outlet pipe group 32 connected to the sub-air chamber 110, so as to accurately adjust and distribute the hot gas flowing downward along the direction of arrow C shown in Figure 2 the upper air outlet pipe group 31 and flowing upward along the direction of arrow C' shown in Figure 2 the lower air outlet pipe group 32, so as to adaptively adjust according to the hot gas air volume required by different types of textiles in different setting processes, and ensure the drying and setting effect of the textiles.

[0099] Refer Figure 18 to Figure 20 As shown, the double-layer stenter 200 includes at least two double-layer setting devices 100, and adjacent double-layer setting devices 100 are all arranged longitudinally along the shell 10 ( Figure 2The side walls are spliced in the direction shown by the X-axis in the figure. The guiding members 23 in adjacent double-layer shaping devices 100 are arranged in a vertical mirror image with respect to the splicing surface formed by the two double-layer shaping devices 100. The casings 10 included in the two double-layer shaping devices 100 are isolated from each other, so that when the hot gas sucked into the air chamber 11 by the air supply mechanism 20 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 conducive to the heat being concentratedly radiated to the textile to be subjected to stentering and shaping. Adjacent double-layer shaping devices 100 are spliced along the longitudinal side walls of the casing 10 and form a splicing surface V (as shown by the dashed line V in Figure 20 the figure), and the guiding members 23 in adjacent double-layer shaping devices 100 included in the double-layer stentering and shaping equipment 200 are arranged in a vertical mirror image with respect to the splicing surface V. The splicing surface V is perpendicular to the horizontal plane.

[0100] As shown in the figure, the double-layer stentering and shaping equipment 200 further includes: fixed brackets 204 arranged on both sides of the first air outlet mechanism 30a and the second air outlet mechanism 30b along the longitudinal direction ( Figure 16 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 textile is stented by the two first amplitude adjustment members 2021 during the process of approaching and separating from each other, and the upper-layer textile is heated by cooperating with the hot gas ejected from the air outlet holes 3001 in the first air pipe group 301 and the second air pipe group 302. The textile is stented by the two second amplitude adjustment members 2031 during the process of approaching and separating from each other, and the lower-layer textile is heated by cooperating with the hot gas ejected from the air outlet holes 3001 in the third air pipe group 303 and the fourth air pipe group 304, so as to realize continuous and efficient stentering and shaping treatment of the textile. Figure 16 As shown in the figure, the double-layer stentering and shaping equipment 200 further includes: a moisture discharge hole 2011 formed at the top of the box body 201, and a dehumidifying 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. Therefore, it is necessary to discharge the moisture with high heat and mixed with oil fume and lint into the external air through the dehumidifying 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 stentering and shaping process at high temperature.

[0101] As shown in the figure, the double-layer stentering and shaping equipment 200 further includes: a moisture discharge hole 2011 formed at the top of the box body 201, and a dehumidifying pipe as shown in Figures 16 to 19 the figure, which is 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. Therefore, it is necessary to discharge the moisture with high heat and mixed with oil fume and lint into the external air through the dehumidifying pipe 205, and it is necessary to always keep the inside of the box body being 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 stentering and shaping process at high temperature.

[0102] The dehumidification duct 205 is provided with a dehumidification fan 206. The dehumidification fan 206 can be arranged at the top of a double-layer stentering and setting system 1000 composed of multiple double-layer stentering and setting devices 200 and is connected to the dehumidification duct 205, so that the dehumidification fan extracts the moisture generated in the box body 201 through the dehumidification duct 205 and discharges it into the external air, so as to always keep the inside of the box body 201 in a negative pressure state. The dehumidification duct 205 can be configured as the outer top of the box body 201 as shown in Figure 17 . Multiple double-layer stentering and setting devices 200 form a double-layer stentering and setting system 1000, and all the dehumidification ducts 205 are spliced into an integral duct 205' along the transverse direction ( Figure 18 the direction shown by the Y axis in Figure 18 ). As shown in Figure 19 , the dehumidification fan 206 is arranged at the end of the integral duct 205', and under the action of the dehumidification fan 206, the moisture in the box body 201 is discharged into the external air; the dehumidification duct 205 on the outer top of the box body 201 can also be independently connected to a dehumidification fan 206, so that under the action of the dehumidification fan 206, the moisture in the box body 201 is discharged into the external air; so as to always keep the inside of the box body 201 in a negative pressure state.

[0103] Based on any one of the technical solutions of the above double-layer stentering and setting device 200 disclosed in the foregoing embodiments and their reasonable combinations, this embodiment also discloses a double-layer stentering and setting system 1000.

[0104] As shown in Figures 16 to 25 , in this embodiment, the double-layer stentering and setting system 1000 includes: a fabric feeding unit 300, at least one double-layer stentering and setting device 200 as disclosed in the above embodiments, and a fabric discharging unit 400; the double-layer stentering and setting device 200 is arranged between the fabric feeding unit 300 and the fabric discharging unit 400. Two layers of textiles arranged vertically up and down are fed into the double-layer stentering and setting device 200 through the fabric feeding unit 300 along the Figure 18 direction shown by the Y axis in Figure 16 for drying, and in the drying process, the first amplitude modulation mechanism 202 and the second amplitude modulation mechanism 203 respectively perform stentering and setting on the two layers of textiles arranged up and down. Finally, the textiles transmitted from the double-layer stentering and setting device 200 are 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 here. The double-layer stentering and setting system 1000 includes at least two double-layer stentering and setting devices 200, and adjacent double-layer stentering and setting devices 200 are spliced along the side wall of the box body 201 in the longitudinal direction (

[0105] the direction shown by the X axis in ). The number of double-layer stentering and setting devices 200 can be 6 to 14 or even more.When the fabric enters the double-layer stenter 200, it can be stentered in the double-layer stenter 200 in sequence, thereby improving the stenter efficiency of the fabric. The gradually increasing temperature inside the box body 201 will be transferred to the adjacent box body 201 due to the heat transfer performance of the steel plate (the box body 201 is preferably made of steel plate material), so as to preheat the adjacent box body 201 to improve the heat utilization rate. Moreover, the double-layer stenter 200 included in the double-layer stenter system 1000 of this embodiment reduces the vertical height and the volume, so as to reduce 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 in the prior art that the large energy consumption of the stenter leads to a large processing cost of the fabric. And the double-layer stenter 200 included in the double-layer stenter system 1000 of this embodiment controls the speed of the fan unit 21 separately to adjust the air volume of the hot gas delivered into the sub-air chamber 110, so as to separately adjust the air volume of the hot gas delivered to the upper gas outlet pipe group 31 or the lower gas outlet pipe group 32 connected to the sub-air chamber 110, and accurately adjust and distribute the hot gas air volume along Figure 2 the direction indicated by the arrow C downward in the Figure 2 or the hot gas air volume ejected upward in the direction indicated by the arrow C' in the lower gas outlet pipe group 32, so as to adaptively adjust according to the hot gas air volume required by different types of fabrics in different stenter processes, and ensure the drying and stenter effect of the fabric.

[0106] Refer Figure 18 to Figure 21 shown. Exemplarily, in some embodiments, the hot air mechanisms 50 of the double-layer stenting devices 100 in each double-layer stenter 200 are all on the same side and have the same air supply direction, both along Figure 18 or Figure 21 the direction indicated by the arrow X1 in the Figure 17 to supply air. The dehumidification pipes 205 in different double-layer stenters 200 are all located on the same side of the top of the box body 201. The dehumidification pipe 205 can be configured as the outer top of the box body 201 as Figure 18 shown. Refer Figure 19 to Figure 21 shown. The dehumidification pipes 205 of multiple double-layer stenters 200 can be connected end to end to form an integral pipe 205'. A dehumidification fan 206 is configured at the end of the integral pipe 205' to exhaust the moisture in the box body 201 under the action of the dehumidification fan 206; or, refer Figure 22As shown, the dehumidification pipes 205 of multiple double-layer stenter setting devices 200 are all connected to a collecting and discharging pipe 207. The dehumidification fan 206 is arranged at the end of the collecting and discharging pipe 207, so that under the action of the dehumidification fan 206, the moisture in the box body 201 is extracted into the collecting and discharging pipe 207 through the dehumidification pipe 205, and then the moisture in the box body 201 is discharged into the external air through the collecting and discharging pipe 207. In addition, the guiding members 23 in the double-layer setting devices 100 included in adjacent double-layer stenter setting devices 200 are arranged in a vertical mirror image along the splicing surface M formed by the two double-layer stenter setting devices 200. Adjacent double-layer stenter setting devices 200 are spliced along the longitudinal side walls of the box body 201 and form a splicing surface M (as Figure 23 shown by the dotted line M in

[0107] Refer Figure 24 to Figure 25 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 arranged in a periodic staggered manner. The air supply directions of the hot air mechanisms 50 in adjacent double-layer stenter setting devices 200 are staggered along the Figure 24 directions shown by the arrow X1 and the arrow X2 in
