Description

Technical Field

[0001] This invention relates to the field of stenter technology, and in particular to a partitioned double-layer stenter device, a double-layer tenter setter, 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

[0077] Please refer to Figures 1 to 23 a specific implementation manner of the disclosed split double-layer shaping device, double-layer stenter setting equipment, system and application.

[0078] It should be noted that the objects processed by the hot gas conveyed by the split double-layer shaping device, double-layer stenter setting equipment, 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 taken 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, determine specific parameters such as the air pressure, temperature, flow rate of the hot gas, and the mixing ratio of the hot gas and air according to the different objects processed by the double-layer stenter setting equipment. At the same time, the heat sources for generating the aforementioned 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.

[0079] Refer to Figures 1 to 9As shown, in this embodiment, the split 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 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 partitions the air chamber 11 to form a first partition air chamber 111 and a second partition air chamber 112 that are isolated from each other, and makes the first partition air chamber 111 communicate with 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 the second partition air chamber 112 communicate with a lower air outlet pipe group 32 formed by the second air outlet pipe group 302 and the fourth air outlet pipe group 304;

[0080] Specifically, the blowing mechanism 20 is axially 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 form an upper air outlet pipe group 31, the second air outlet pipe group 302 and the fourth air outlet pipe group 304 form a lower air outlet pipe group 32, and the upper air outlet pipe group 31 ejects hot gas downward in a vertical or approximately vertical direction (i.e., Figure 7 the direction shown by arrow C in the figure), and the lower air outlet pipe group 32 ejects hot gas upward in a vertical or approximately vertical direction (i.e., Figure 7 the direction shown by arrow C' in the figure), and the hot gas is uniformly ejected onto the fabric downward in the direction shown by arrow C and upward in the direction shown by arrow C' through the upper air outlet pipe group 31 and the lower air outlet pipe group 32 respectively to convectively heat the fabric. The partitioning mechanism 40 is disposed in the air chamber 11, and the partitioning mechanism 40 is used to form a first partition air chamber 111 and a second partition air chamber 112 that are isolated from each other in the air chamber 11, and makes the first partition air chamber 111 and the second partition air chamber 112 that are isolated from each other communicate with the upper air outlet pipe group 31 and the lower air outlet pipe group 32 respectively.

[0081] Refer Figures 1 to 9 ​​As shown, the air supply mechanism 20 includes a plurality of first air supply units 21 and second air supply units 22 arranged laterally in the first partition air chamber 111 and the second partition air chamber 112, respectively. The first turbine 211 included in the first air supply unit 21 and the second turbine 221 included in the second air supply unit 22 are axially offset. The first air supply unit 21 and the second air supply unit 22 respectively drive the first turbine 211 and the second turbine 221 to rotate to deliver hot gas to the first partition air chamber 111 and the second partition air chamber 112, respectively, and deliver it to the upper air outlet pipe group 31 and the lower air outlet pipe group 32, respectively, and independently adjust the air volume of the upper air outlet pipe group 31 and the lower air outlet pipe group 32. The first partition air chamber 111 is provided with a plurality of first air supply units 21, and the second partition air chamber 112 is provided with a plurality of second air supply units 22, and the first turbine 211 arranged in the first partition air chamber 111 and the second turbine 221 arranged in the second partition air chamber 112 are axially offset.

[0082] For example, the reference Figures 1 to 3 and Figure 9 As shown, the first air supply unit 21 drives the first turbine 211 to rotate, thereby delivering hot gas to the first partition air chamber 111 and further delivering the hot gas to the upper exhaust pipe group 31 connected to the first partition air chamber 111. By controlling the rotational speed of the first turbine 21 driven by the several first air supply units 21 in the first partition air chamber 111, the airflow of the hot gas delivered to the first partition air chamber 111 is adjusted, thereby achieving individual adjustment of the airflow of the hot gas delivered to the upper exhaust pipe group 31. The second air supply unit 22 drives the second turbine 221 to rotate, thereby delivering hot gas to the second partition air chamber 112 and further delivering the hot gas to the lower exhaust pipe group 32 connected to the second partition air chamber 112. By controlling the rotational speed of the second turbine 221 driven by the several second air supply units 22, the airflow of the hot gas delivered to the second partition air chamber 112 is adjusted, thereby achieving individual adjustment of the airflow of the hot gas delivered to the lower exhaust pipe group 32, so as to precisely adjust and distribute the airflow along the upper exhaust pipe group 31. Figure 7 The direction indicated by the middle arrow C is downward and parallel to the lower exhaust pipe assembly 32. Figure 7 The upward flow of hot gas, indicated by the middle arrow C'.

[0083] 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 partitioned double-layer finishing device 100 needs to increase the rotational speed of the second turbine 221 driven by several second air supply units 22 for delivering hot gas to the lower air outlet assembly 32, thereby increasing the air volume of hot gas delivered to the lower air outlet assembly 32 and increasing the air volume along the lower air outlet assembly 32. Figure 7 The upward ejection of hot gas in the direction indicated by the middle arrow C', or the reduction of the rotational speed of the first turbine 211 driven by several first air supply units 21 used to deliver hot gas to the upward exhaust pipe assembly 31, in order to reduce the upward air outlet assembly 31 along the direction indicated by the middle arrow C'. Figure 7 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 7 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 7 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 7 Excessive downward airflow, as indicated by the middle arrow C, causes the wet fabric to sag excessively, which could negatively impact the drying effect.

[0084] 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 segmented double-layer setting device 100 controls the rotation speed of the first turbine 211 and the second turbine 221 by separately controlling the rotation speed of several first air supply units 21 and second air supply units 22. This allows for individual regulation of the hot gas flow delivered to the first segmented air chamber 111 and the second segmented air chamber 112, thereby enabling individual regulation of the hot gas flow delivered to the upper air outlet assembly 31 and the lower air outlet assembly 32. This allows for precise adjustment and distribution of the hot gas flow along the upper air outlet assembly 31. Figure 7 The direction indicated by the middle arrow C is downward and parallel to the lower exhaust pipe assembly 32. Figure 7 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.

[0085] Preferably, the reference Figures 1 to 9As shown, the split double-layer shaping device 100 further includes a control system (not shown) for controlling the rotation speeds of the first air supply unit 21 and the second air supply unit 22 to drive the first turbine 211 and the second turbine 221 respectively. By controlling the rotation speeds of the first air supply unit 21 and the second air supply unit 22 to drive the first turbine 211 and the second turbine 221 respectively through the control system, the hot gas flow rates delivered by the first turbine 211 and the second turbine 221 to the first partition air chamber 111 and the second partition air chamber 112 are adjusted, so as to separately adjust the hot gas flow rates delivered to the upper outlet pipe group 31 and the lower outlet pipe group 32, and to accurately adjust and distribute the hot gas flow rate of the upper outlet pipe group 31 along Figure 7 the direction of the arrow C shown in Figure 7 downward and the hot gas flow rate of the lower outlet pipe group 32 ejected upward along the direction of the arrow C' shown in

[0086] are adaptively adjusted according to the hot gas flow rates required by different types of textiles in different shaping processes, so as to ensure the drying and shaping effect of the textiles. Optionally, the aforementioned control system is an inverter for controlling the rotation of the first air supply unit 21 and the second air supply unit 22 and a main control unit for controlling the inverter.

[0091] As shown in Figures 2 to 7 , the partitioning mechanism 40 includes: at least one first partitioning portion 43, at least one second partitioning portion 44, and a connecting partition portion 45 connecting the first partitioning portion 43 and the second partitioning portion 44; the first partitioning portion 43 and the second partitioning portion 44 are connected by the connecting partition portion 45 to partition the outer air chamber 114 and form the mutually isolated first outer sub-air chamber 1141 and second outer sub-air chamber 1142, and the first outer sub-air chamber 1141 and the second outer sub-air chamber 1142 are respectively connected to the first sub-pipe group 121 and the fourth sub-pipe group 124; the first partition plate 41 is configured with a first notch 411 for the first outer sub-air chamber 1141 to communicate with the third sub-pipe group 123 and a second notch 412 for the second outer sub-air chamber 1142 to communicate with the inner air chamber 113, and the first notch 411 and the second notch 412 are distributed in an offset manner relative to the connecting partition portion 45; the first outer sub-air chamber 1141 connecting the first sub-pipe group 121 and the third sub-pipe group 123 forms the first partition air chamber 111, and the second outer sub-air chamber 1142 connecting the inner air chamber 113 and the fourth sub-pipe group 124 forms the second partition air chamber 112.

[0092] Specifically, the air chamber 11 is separated by a first partition plate 41 to form an inner air chamber 113 and an outer air chamber 114, so that the outer air chamber 114 connects the first sub-tube group 121 and the fourth sub-tube group 124. The inner air chamber 113 is isolated from the third sub-tube group 123 by a second partition plate 42, so that the inner air chamber 113 connects the second sub-tube group 122. The first partition portion 43 and the second partition portion 44 are connected by a connecting partition portion 45 to partition the outer air chamber 114 and form a first outer sub-air chamber 1141 and a second outer sub-air chamber 1142 that are isolated from each other. The first outer sub-air chamber 1141 and the second outer sub-air chamber 1142 are respectively connected to the first sub-tube group 121 and the fourth sub-tube group 124. The first partition plate 41 is configured with a first notch 411 for the first outer sub-air chamber 1141 to connect to the third sub-tube group 123, and a second notch 412 for the second outer sub-air chamber 1142 to connect to the inner air chamber 113. Thus, the first outer sub-air chamber 1141 that connects the first sub-tube group 121 and the third sub-tube group 123 forms a first partition air chamber 111, and the second outer sub-air chamber 1142 that connects the inner air chamber 113 and the fourth sub-tube group 124 forms a second partition air chamber 112.

[0093] As shown in Figures 2 to 7 Figure 5, the first air supply unit 21 includes: a first sealing plate 213 disposed on the side wall of the housing 10, a first driving unit 212 disposed on the first sealing plate 213, and a first turbine 211 formed in the first outer sub-air chamber 1141. The driving shaft of the first driving unit 212 penetrates through the first sealing plate 213 and extends into the inner air chamber 113 to connect the first turbine 211. The first sealing plate 213 is used to support and fix the first driving unit 212 and seal the connection between the first driving unit 212 and the housing 10, preventing the hot gas in the first outer sub-air chamber 1141 from leaking. The first driving unit 212 drives the first turbine 211 to rotate in the first outer sub-air chamber 1141 to suck the hot gas into the first outer sub-air chamber 1141, and further convey the hot gas along Figure 5 the directions indicated by the arrows D1 and D3 in Figure 5 to the first sub-tube group 121 and the third sub-tube group 123 respectively, so as to further convey the hot gas along Figure 7 the directions indicated by the arrows D11 and D31 in Figure 5 to the first air outlet tube group 301 and the third air outlet tube group 303 respectively.

[0094] The first air supply unit 21 includes: a spacer ring 223 axially clamped between the housing 10 and the first partition plate 41 and formed in the second outer sub-air chamber 1142. The spacer ring 223 penetrates through the side wall of the housing 10 and encloses an assembly groove 224 isolated from the second outer sub-air chamber 1142. A second sealing plate 225 disposed on the first partition plate 41 and formed in the assembly groove 224, a second driving unit 222 disposed on the second sealing plate 225, and a second turbine 221 formed in the inner air chamber 113. The driving shaft of the second driving unit 222 penetrates through the second sealing plate 225 and extends into the inner air chamber 113 to connect with the second turbine 221. The second sealing plate 2253 and the second driving unit 222 are isolated from the second outer sub-air chamber 1142 by the spacer ring 223, so that the second driving unit 222 is formed in the assembly groove 224 to reduce space occupation, and the second sealing plate 2253 is used to support and fix the second driving unit 222 and seal the connection between the second driving unit 222 and the first partition plate 41 to prevent the hot gas in the inner air chamber 113 from leaking. The second driving unit 222 drives the second turbine 221 to rotate in the inner air chamber 113 to suck the hot gas into the inner air chamber 113, and further conveys the hot gas along the Figure 6 directions indicated by the arrows D2 and D24 in the figure to the second sub-tube group 122 and the second outer sub-air chamber 1142 respectively, and then conveys the hot gas along the Figure 6 direction indicated by the arrow D4 in the figure to the fourth sub-tube group 124 through the second outer sub-air chamber 1(1)42, so as to convey the hot gas along the Figure 7 directions indicated by the arrows D21 and D41 in the figure to the second air outlet tube group 302 and the fourth air outlet tube group 304 respectively through the second sub-tube group(1)22 and the fourth sub-tube group 124.

[0095] Optionally, the first air supply unit 21 and the second air supply unit 22 can be configured as centrifugal fans, and the first driving unit 212 and the second driving unit 222 can be configured as three-phase AC motors. The three-phase AC motors are independently regulated in speed by a control system (not shown) to respectively control the rotation speeds of the first turbine 211 and the second turbine 221, so as to respectively control the air volume of the hot gas conveyed to the first outer sub-air chamber 1141 and the inner air chamber 113. It should be noted that the first turbine 211 and the second turbine 221 can be components such as impellers and blades, as long as they can suck the hot gas into the first partition air chamber 111 and the second partition air chamber 112.

[0096] Refer to Figure 4As shown, the first turbine 211 and the second turbine 221 are axially offset. The first driving unit 212 and the second driving unit 222 respectively drive the first turbine 211 and the second turbine 221 to rotate to respectively deliver hot gas to the first outer sub-air chamber 1141 and the inner air chamber 113. By controlling the rotation speed of the first driving unit 212 driving the first turbine 211, the air volume of the hot gas delivered to the first outer sub-air chamber 1141 is separately adjusted, so as to separately adjust the air volume of the hot gas delivered to the upper air outlet pipe group 31, and accurately adjust and distribute the air volume of the hot gas ejected downward along the Figure 7 direction indicated by the arrow C in the figure. By controlling the rotation speed of the second driving unit 222 driving the second turbine 221, the air volume of the hot gas delivered to the inner air chamber 113 is separately adjusted, so as to separately adjust the air volume of the hot gas delivered to the lower air outlet pipe group 32, and accurately adjust and distribute the air volume of the hot gas ejected downward along the Figure 7 direction indicated by the arrow C in the figure, and adaptively adjust according to the air volume of the hot gas required by different types of textiles in different shaping processes, so as to ensure the drying and shaping effect of the textiles.

[0097] Refer Figure 1 to Figures 13 to 15 As shown, the separated 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 54 for forming hot gas in the combustion chamber 51, and a hot air pipe 52 connecting the combustion chamber 51 and the housing 10. The combustion chamber 51 is provided with a ventilation hole (not marked) for laterally sucking air, and the ventilation hole (not marked) is covered with a filter screen 53. Preferably, the heating source is configured as a burner 54 detachably disposed 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 (for example, natural gas). Under the action of a number of first air supply units 21 and second air supply units 22, the hot gas is respectively delivered from the combustion chamber 51 to the first separated air chamber 111 and the second separated air chamber 112 through the hot air pipe 52, and further delivered to the upper air outlet pipe group 31 and the lower air outlet pipe group 32, so that the upper air outlet pipe group 31 and the lower air outlet pipe group 32 eject hot gas to dry and shape the textiles.

[0098] The hot air pipe 52 is configured with a plurality of hot air distribution pipes 521 connecting the air chamber 11, or the hot air pipe 52 is configured with a plurality of hot air distribution ports 522 connecting the air chamber 11. As Figure 13As shown, the hot air duct 52 can be configured with a hot air distribution duct 521 for delivering hot gas to the sub-air chamber 110. The number of hot air distribution ducts 521 is the same as the total number of the first air supply units 21 and the second air supply units 22. The first air supply units 21 and the second air supply units 22 suck the hot gas in the hot air duct 52 and deliver it to the first outer sub-air chamber 1141 and the inner air chamber 113 respectively. As Figure 14 As shown, the hot air duct 52 can also be configured with a hot air distribution port 1422 for delivering hot gas to the sub-air chamber 110. The number of hot air distribution ports 1422 is the same as the total number of the first air supply units 21 and the second air supply units 22. The first air supply units 21 and the second air supply units 22 suck the hot gas in the hot air duct 52 and deliver it to the first outer sub-air chamber 1141 and the inner air chamber 113 respectively. A set of hot air mechanisms 50 generates hot gas and delivers the hot gas to the first partition air chamber 111 and the second partition air chamber 112 simultaneously through the hot air duct 52, and then several first air supply units 21 and second air supply units 22 respectively deliver the hot gas in the hot air duct 52 to the upper air outlet pipe group 31 and the lower air outlet pipe group 32, so that the upper air outlet pipe group 31 and the lower air outlet pipe group 32 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 sets of stenters arranged up and down and separated by partition plates in the prior art, the overall vertical height of the partitioned double-layer setting device 100 is reduced, so that the structure of the partitioned double-layer setting device 100 is more compact, reducing the occupation of space resources. Moreover, the partitioned double-layer setting device 100 provides hot gas to the first partition air chamber 111 and the second partition air chamber 112 simultaneously 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 sets of stenters arranged up and down and separated by partition plates in the prior art.

[0099] Refer to Figures 2 to 6As shown, the housing 10 has a first air duct 101 formed in the inner air chamber 113 and isolated from the inner air chamber 113, and passing through the first partition 41. The first air duct 101 is connected to the hot air distribution pipe 521 or the hot air distribution port 522 to guide hot gas to the first turbine 211. The first drive unit 212 drives the first turbine 211 to rotate, which can guide the hot gas in the hot air pipe 52 through the first air duct 101 to the first turbine 211, so that the hot gas can be further drawn into the first outer air chamber 1141 by the second turbine 221. The first air duct 101 is isolated from the inner air chamber 113 to prevent hot gas from mixing into the inner air chamber 113. The housing 10 also has a second air duct 102 formed in the inner air chamber 113. The second air duct 102 is connected to the hot air distribution pipe 521 or the hot air distribution port 522 to guide hot gas to the second turbine 221. The second drive unit 222 drives the second turbine 221 to rotate, which can guide the hot gas in the hot air pipe 52 through the second air duct 102 to the second turbine 221, so that the hot gas can be further drawn into the inner wind chamber 113 by the second turbine 221.

[0100] The second partitioned air chamber 112 includes: a second air duct 1132 for hot gas in the inner air chamber 113 to flow to the second sub-pipe group 122, and a fourth air duct 1134 for hot gas in the second outer sub-air chamber 1142 to flow to the fourth sub-pipe group 124. The second turbine 221 is driven by the second drive unit 222 to rotate within the inner air chamber 113, thereby drawing hot gas into the inner air chamber 113 and further dispersing the hot gas along the inner air chamber 113. Figure 6 The air is conveyed in the directions indicated by the middle arrows D2 and D24 to the second air duct 1132 and the second outer sub-air chamber 1142, respectively. Then, through the second air duct 1132 and the second outer sub-air chamber 1142, the hot gas is conveyed to the second sub-pipe group 122 and the fourth air duct 1134, respectively. Finally, through the fourth air duct 1134, the hot gas is further conveyed along... Figure 6 The gas is conveyed in the direction indicated by the middle arrow D4 to the fourth sub-tube group 124, so that the hot gas is conveyed along the path indicated by the second sub-tube group 122 and the fourth sub-tube group 124. Figure 7 The air is delivered to the second exhaust pipe group 302 and the fourth exhaust pipe group 304 in the directions indicated by the middle arrows D21 and D41, respectively.

[0101] The first partitioned air chamber 111 includes: a first air duct 1131 for hot gas to flow from the first outer sub-air chamber 1141 to the first sub-pipe group 121, and a third air duct 1133 for hot gas to flow from the first outer sub-air chamber 1141 to the third sub-pipe group 123. The first turbine 211 is driven by the first drive unit 212 to rotate within the first outer sub-air chamber 1141, thereby drawing hot gas into the first outer sub-air chamber 1141 and further dispersing the hot gas along... Figure 5The arrows D1 and D3 respectively convey the hot gas to the first air duct 1131 and the third air duct 1133, and then the first air duct 1131 and the third air duct 1133 respectively convey the hot gas to the first sub-tube group 121 and the third sub-tube group 123, so as to further convey the hot gas along the Figure 7 directions shown by the arrows D11 and D31 in the figure to the first air outlet pipe group 301 and the third air outlet pipe group 303 respectively.

[0102] Refer to Figures 2 to 6 and Figure 10 As shown, exemplarily, in some embodiments, the first air supply unit 21 further includes: a guiding member 23 symmetrically arranged along the axis center of the first turbine 211 in the first outer sub-air chamber 1141 and formed around the first turbine 211. The guiding member 23 divides the first outer sub-air chamber 1141 to form a guiding air duct 231, and the guiding air duct 231 forms two air supply openings 2311 with opposite outlet directions along the vertical direction; the first driving unit 212 drives the first turbine 211 to rotate to suck the hot gas into the first outer sub-air chamber 1141, and makes the hot gas flow in a swirling direction in the guiding air duct 231 and be respectively conveyed to the first sub-tube group 121 and the third sub-tube group 123 through the two air supply openings 2311 with opposite outlet directions. The first driving unit 212 drives the first turbine 211 to rotate to suck the hot gas into the first outer sub-air chamber 1141, and makes the hot gas flow in a swirling direction in the guiding air duct 231. The guiding member 23 divides the hot gas flowing in a swirling direction in the guiding air duct 231 into two hot gas flows. The guiding member 23 guides the two hot gas flows to be respectively sent into the first air duct 1131 and the third air duct 1133 through the two air supply openings 2311 along the vertical direction and with opposite outlet directions (along the Figure 10 directions shown by the arrow D1 and the arrow D3 in the figure), and then the first air duct 1131 and the third air duct 1133 respectively convey the hot gas to the first sub-tube group 121 and the third sub-tube group 123.

[0103] Specifically, the guiding member 23 includes: a guiding air plate 232 extending obliquely relative to the axis of the housing 10, and a side plate 233 constructed at the extending end of the guiding air plate 232 and extending away from the axis of the housing 10; during the process of the hot gas flowing in a swirling direction in the guiding air duct 231, the two sets of side plates 233 can divide the hot gas flowing in a swirling direction in the guiding air duct 231 into two hot gas flows, and cooperate with the guiding air plate 232 to guide the two hot gas flows to be respectively sent into the first air duct 1131 and the third air duct 1133 along two opposite directions (along the Figure 10 directions shown by the arrow D1 and the arrow D3 in the figure) and through the air supply openings 2311, and then the first air duct 1131 and the third air duct 1133 respectively convey the hot gas to the first sub-tube group 121 and the third sub-tube group 123.

[0104] It should be noted that in this embodiment, preferably, refer to 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 11 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 11 The inclined second partition 44' shown by the dashed line can be used as long as it can isolate the adjacent outer sub-air chamber 1140 and allow the hot gas in the adjacent outer sub-air chamber 1140 to be transported to the corresponding connected upper air outlet group 31 and lower air outlet group 32.

[0105] It should be noted that in some embodiments, the references Figure 11 As shown, the first partition 43 and the second partition 44 are offset laterally and spaced apart, or, see... Figure 12 As shown, the first partition 43 and the second partition 44 are staggered along the transverse portion. Both of the aforementioned distribution methods of the first partition 43 and the second partition 44 within the housing 10 (i.e., the first partition 43 and the second partition 44 are staggered and spaced apart along the transverse portion, and the first partition 43 and the second partition 44 are staggered along the transverse portion) cause the connecting partition 45 to tilt. The position of the guide 23 disposed on the connecting partition 45 will change as the connecting partition 45 tilts, thereby increasing the space occupied by the connecting partition 45 and the guide 23 within the housing 10. Therefore, in this embodiment, it is preferable that the connecting partition 45 is vertically arranged and connects the adjacent ends of the first partition 43 and the second partition 44 that are close to each other, to reduce the space occupied by the connecting partition 45 and the guide 23 within the housing 10.

[0106] The extension direction of the air guide plate 232 and the extension direction of the side plate 233 form an angle α that is tangent to the swirling flow direction of the hot gas inside the air guide duct 231. The angle α is greater than 0° and less than 180°. It should be noted that the side plate 233 can also be configured as a linear plate (not shown) or... Figure 10 The arc-shaped plate shown, the air guide plate 232 can also be configured as follows: Figure 10 The linear or arc-shaped plate shown (not shown) can be used as long as it can guide the two streams of hot gas out in two opposite vertical directions. In this embodiment, the air guide plate 232 is preferably as shown. Figure 10 The linear plate shown, wherein the side plate 233 is preferably as follows: Figure 10The arcuate plate body shown in the figure, the included angle α is formed by the extending direction of the air guide plate 232 configured as a linear plate body and the tangent Q of the side plate 233 configured as an arcuate plate body. When the position of the side plate 233 remains unchanged and the included angle α is smaller, the distance between the air guide plate 232 and the first turbine 211 is larger, and the space of the air guide duct 231 formed by the air guide plate 232 is also larger, resulting in an increase in the air flow rate of the hot gas that the air guide 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 fabric. In actual use, the air flow rate of the hot gas that the air guide 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.

[0108] Specifically, the first sub-tube group 121, the second sub-tube group 122, the third sub-tube group 123 and the fourth sub-tube group 124 all include a plurality of air guiding openings 1201 corresponding to and communicating with the air outlet pipe, and the air outlet pipe and the air guiding openings 1201 form a detachable connection.

[0109] Based on the technical solution of a partitioned double-layer shaping device 100 disclosed in the foregoing embodiments, the present embodiment also discloses a double-layer stenter 200.

[0110] See Figure 15As shown, in this embodiment, the double-layer stenter 200 includes: a box body 201, at least one axially arranged split double-layer shaping device 100 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 fabric, and a second amplitude adjustment mechanism 203 formed between the third air outlet pipe group 303 and the fourth air outlet pipe group 304 for stretching the fabric. The first amplitude adjustment mechanism 202 and the second amplitude adjustment mechanism 203 stretch the two layers of fabric arranged up and down 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 split double-layer shaping device 100. The double-layer stenter 200 equipped with the split double-layer shaping device 100 can perform compound drying and shaping on the two layers of fabric arranged up and down, and reduces the vertical height of the double-layer stenter 200, thereby making the structure of the double-layer stenter 200 more compact, reducing the occupation of space resources, and the double-layer stenter 200 can provide hot gas for the inner air chamber 113 and several first outer sub-air chambers 1141 through a set of hot air mechanism 50, further reducing energy consumption, reducing the production cost and manufacturing cost of compound drying and shaping of the fabric, and overcoming the problems of large space occupation, high energy consumption and uneven heat distribution in the single double-layer stenter due to the heat distribution caused by the partition plate in the existing double-layer stenter device in the prior art. And, by controlling the rotational speeds of the first turbine 211 and the second turbine 221 driven by a number of first air supply units 21 and second air supply units 22 in the first partition air chamber 111 and the second partition air chamber 112 respectively, the air volume of the hot gas delivered to the first partition air chamber 111 and the second partition air chamber 112 is adjusted separately, so as to realize the separate adjustment of the air volume of the hot gas delivered to the upper air outlet pipe group 31 and the lower air outlet pipe group 32, so as to accurately adjust and distribute the hot gas volume of the upper air outlet pipe group 31 along Figure 7 the direction of the arrow C shown in Figure 7 downward and the hot gas volume of the lower air outlet pipe group 32 ejected upward along the direction of the arrow C' shown in

[0111] For reference Figure 19 As shown, the double-layer stenter 200 includes at least two split double-layer shaping devices 100, and the adjacent split double-layer shaping devices 100 are arranged longitudinally along the shell 10 ( Figure 1Side wall splicing in the direction shown by the X-axis in the figure. The casings 10 included in the two double-layer shaping devices 100 are isolated from each other, so that when the hot gas sucked by the air supply mechanism 20 into the air chamber 11 is sent into the first air outlet mechanism 30a and the second air outlet mechanism 30b, the hot gas in the two casings 10 will not interfere with each other, avoiding affecting the uniformity of the hot gas sent into the first air outlet mechanism 30a and the second air outlet mechanism 30b, and being beneficial to the heat being concentratedly radiated to the textile being subjected to stentering and shaping.

[0112] Refer Figure 15 As shown, the double-layer stentering and shaping equipment 200 further includes: fixed brackets 204 arranged on both sides of the air outlet mechanism along the longitudinal direction ( Figure 1 the direction shown by the X-axis in the figure). The first amplitude adjustment mechanism 202 includes: two first amplitude adjustment members 2021 arranged horizontally on the fixed brackets 204. The second amplitude adjustment mechanism 203 includes: two second amplitude adjustment members 2031 arranged horizontally on the fixed brackets 204; the two first amplitude adjustment members 2021 are used for stentering the textile when approaching each other, and the two second amplitude adjustment members 2031 are used for stentering the textile when approaching each other. By the two first amplitude adjustment members 2021 stentering the textile during the process of approaching and separating from each other, and cooperating with the hot gas ejected from the air holes 3001 in the first air pipe group 301 and the second air pipe group 302 to heat the upper-layer textile, and by the two second amplitude adjustment members 2031 stentering the textile during the process of approaching and separating from each other, and cooperating with the hot gas ejected from the air holes 3001 in the third air pipe group 303 and the fourth air pipe group 304 to heat the lower-layer textile, so as to realize continuous and efficient stentering and shaping treatment of the textile.

[0113] Refer Figure 16 As shown, 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 of 201. Since the double-layer shaping device 100 will cause the temperature inside the box body of 201 to continuously rise during operation, the moisture generated inside the box body of 201 carries high heat. Therefore, it is necessary to discharge the moisture with high heat and mixed with oil fume and lint to the external air through the dehumidifying pipe 205, and it is necessary to always keep the inside of the box body of 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 of 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. The dehumidifying pipe 205 can be configured as shown in Figure 16 at the outer top of the box body of 201. Multiple double-layer stentering and shaping equipment 200 form a double-layer stentering and shaping system 1000, and all the dehumidifying pipes 205 are spliced into an integral pipe 205' along the transverse direction ( Figure 17 the direction shown by the Y-axis in the figure), as shown in Figure 17 As shown in Figure 18 , the centrifugal fan 206 is arranged at the end of the overall pipeline 205', and under the action of the centrifugal fan 206, the moisture in the box body 201 is pumped out into the external air; alternatively, the dehumidification pipeline 205 on the outer top of the box body 201 can be independently connected to a centrifugal fan 206, so that under the action of the centrifugal fan 206, the moisture in the box body 201 is pumped out into the external air; in order to always keep the inside of the box body 201 in a negative pressure state.

[0114] Based on the technical solutions of any one of the double-width stenter devices 200 disclosed in the foregoing embodiments and their reasonable combinations, this embodiment also discloses a double-width stenter system 1000.

[0115] Refer Figures 15 to 23 As shown in Figure 15 , in this embodiment, the double-width stenter system 100 includes: a fabric feeding unit 300, at least one double-width stenter device 200 as disclosed in the embodiment, and a fabric discharging unit 500; the double-width stenter device 200 is arranged between the fabric feeding unit 300 and the fabric discharging unit 500. The fabric is fed into the double-width stenter device 200 through the fabric feeding unit 300 for drying, and during the drying process, the first amplitude adjustment mechanism 202 and the second amplitude adjustment mechanism 203 respectively perform width setting on the two layers of fabrics arranged up and down. Finally, the fabric transmitted from the double-width stenter device 200 is arranged neatly by the fabric discharging unit 400 to complete the whole process. The fabric feeding unit 300 and the fabric discharging unit 400 are both prior arts, so they will not be elaborated here. The double-width stenter system 1000 includes at least two double-width stenter devices 200, and two adjacent double-width stenter devices 200 are spliced along the side wall of the box body 201 in the longitudinal direction ( Figure 15 the direction shown by the X-axis in Figure 15 ). The number of double-width stenter devices 200 can be 6 to 14 or even more.

[0116] ​​When the fabric enters the double-layer stenter 200, it can be stentered and shaped through the double-layer stenter 200 in sequence, thereby improving the stenter and shaping 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 rotation speeds of a number of first air supply units 21 and second air supply units 22 in the first partition air chamber 111 and the second partition air chamber 112 respectively to drive the first turbine 211 and the second turbine 221, so as to separately adjust the air volume of the hot gas delivered into the first partition air chamber 111 and the second partition air chamber 112, thereby realizing separately adjusting the air volume of the hot gas delivered to the upper gas outlet pipe group 31 and the lower gas outlet pipe group 32, so as to precisely adjust and distribute the hot gas volume along Figure 7 the direction shown by the arrow C downward in the middle and the lower gas outlet pipe group 32 along Figure 7 the direction shown by the arrow C' upward in the middle, so as to adaptively adjust according to the hot gas volume required by different types of fabrics in different shaping processes, and ensure the drying and shaping effect of the fabric.

[0117] Refer Figure 17 to Figure 20 , exemplarily, in some embodiments, the hot air mechanisms 50 of the double-layer shaping devices 100 in each double-layer stenter 200 are all on the same side and have the same air supply direction. The hot air mechanisms 50 all supply air along Figure 17 and Figure 20 the direction shown by the arrow X1 in the middle. 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. Refer Figure 17 to Figure 18 , the dehumidification pipe 205 can be configured as the outer top of the box body 201 as Figure 16 shown. The dehumidification pipes 205 of multiple double-layer stenters 200 can be connected end to end to form an integral pipe 205'. A centrifugal 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 centrifugal fan 206; or, refer Figure 20 to Figure 21As shown, the dehumidifying pipelines 205 of multiple double-layer stenter setting devices 200 are all connected to a collecting and discharging pipeline 207. A centrifugal fan 206 is arranged at the end of the collecting and discharging pipeline 207, so as to draw the moisture in the box body 201 into the collecting and discharging pipeline 207 through the dehumidifying pipeline 205 under the action of the centrifugal fan 206, and then discharge the moisture in the box body 201 into the external air through the collecting and discharging pipeline 207.

[0118] Refer Figure 22 to Figure 23 As shown, exemplarily, in some embodiments, the air supply directions of the hot air mechanisms 50 in adjacent double-layer stenter setting devices 200 can also be configured to be periodically staggered. The air supply directions of the hot air mechanisms 50 in adjacent double-layer stenter setting devices 200 are staggered along the Figure 22 directions shown by the arrow X1 and the arrow X2 in the figure. The dehumidifying pipelines 205 of multiple double-layer stenter setting devices 200 are all connected to a collecting and discharging pipeline 207, so as to improve the uniformity of the temperature distribution in the double-layer stenter setting system 1000.
