Description

Technical Field

[0001] This invention relates to the field of stenter technology, and in particular to a dual-outlet compound 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 tenter frame device and system. In this prior art, it consists of two sets of tenter frames arranged vertically and separated by a partition plate. Each set of tenter frames generates heat through combustion in 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 tenter frame the textile. The two sets of tenter frames are stacked together to achieve the purpose of tenter frame setting the two sets of textiles separately.

[0004] However, the aforementioned existing double-layer tenter styling device requires two independent stenters to achieve double-layer tentering of two sets of textiles. These two stenters are two separate systems, and their stacking increases space requirements. Furthermore, the heat generated by the burner is dispersed within a large volume enclosed by the stenter housing, resulting in low heat utilization and high energy consumption. Additionally, the internal partitions in the existing double-layer tenter styling device lead to uneven heat distribution within the device.

[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

[0025] Compared with the prior art, the beneficial effects of the present invention are: In this application, the air chamber is divided by a guide component inside the air chamber to form an air duct in which the heating gas flows in a swirling direction and is sent out in two opposite directions.

[0029] Please refer to Figures 1 to 20 A specific implementation of the disclosed double - outlet compound setting device, double - layer stenter equipment, system and application.

[0030] It should be noted that the objects processed by the hot gas conveyed by the double - outlet compound setting device, double - layer stenter 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, coated fabrics, wool, cotton, polyester and cloth, etc., 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 elaboration and is applicable to other types of fabrics. Those skilled in the art can reasonably select the hot gas (for example, the hot air generated by a burner) conveyed by the air supply mechanism according to the different objects processed by the double - layer stenter equipment, and determine specific parameters such as the air pressure, temperature, flow rate of the hot gas, and the mixing ratio of hot gas and air. At the same time, the heat sources for generating the aforementioned hot gas include, but are not limited to, burners using natural gas as energy, or heat exchangers using heat - conducting oil or steam as heat - exchange media.

[0031] Refer Figures 1 to 4 As shown, in this embodiment, the double - outlet compound setting device 1 includes: a housing 11 with an air chamber 110, a double - outlet air supply mechanism 12 axially disposed in the housing 11, a first air outlet mechanism 13a and a second air outlet mechanism 13b symmetrically arranged along the axis of the housing 11 and connected to the air chamber 110, and a hot - air mechanism 14 formed axially between the first air outlet mechanism 13a and the second air outlet mechanism 13b and connected to the air chamber 110; the double - outlet air supply mechanism 12 includes: an air supply component 122, and a guiding member 123 symmetrically arranged along the axis center in the air chamber 110 and formed around the air supply component 122; the guiding member 123 divides the air chamber 110 to form a guiding air duct 111, and the guiding air duct 111 forms two air supply openings 1111 with opposite outlet directions along the vertical direction; the air supply component 122 sucks the hot gas in the hot - air mechanism 14 into the air chamber 110, and the hot gas flows in a swirling direction in the guiding air duct 111 and is respectively conveyed into the first air outlet mechanism 13a and the second air outlet mechanism 13b through the two air supply openings 1111 with opposite outlet directions.

[0032] By sucking the hot gas provided by the hot - air mechanism 14 through the air supply component 122, the hot gas flows in the direction shown by arrow A in Figure 2 The air supply component 122 sucks the hot gas into the air chamber 110 and guides the hot gas to flow in a swirling direction in the guiding air duct 111. The guiding member 123 evenly divides the hot gas flowing in a swirling direction in the guiding air duct 111 into two hot gases, and the guiding member 123 guides the two hot gases to flow vertically and in opposite outlet directions (that is, as shown in Figure 4Two air outlets 1111 (in the directions indicated by arrows N1 and N2) respectively send air into the first air outlet mechanism 13a and the second air outlet mechanism 13b, and pass through the first air outlet mechanism 13a and the second air outlet mechanism 13b to blow hot air downward along the vertical or approximately vertical direction (i.e., Figure 2 in the direction indicated by arrow C in the figure) and upward along the vertical or approximately vertical direction (i.e., Figure 2 in the direction indicated by arrow C' in the figure) to uniformly spray hot air on the fabric for convective heating of the fabric, so that the drying of the fabric by the hot air is more uniform, and finally the drying and shaping effect of the fabric is improved. Therefore, a set of hot air mechanisms 14 generates hot air, and then the double-outlet air supply mechanism 12 uniformly sends the hot air generated by the hot air mechanisms 14 into the first air outlet mechanism 13a and the second air outlet mechanism 13b respectively, so that the first air outlet mechanism 13a and the second air outlet mechanism 13b can simultaneously and respectively perform double-layer drying and shaping on two layers of fabric. Compared with the double-layer stenter setting device composed of two sets of stenters arranged up and down and separated by a partition plate in the prior art, the double-outlet double-layer setting device 1 as a whole reduces the vertical height, thereby making the structure of the double-outlet double-layer setting device 1 more compact, reducing the occupation of space resources, and the double-outlet double-layer setting device 1 can provide hot air for the first air outlet mechanism 13a and the second air outlet mechanism 13b through a set of hot air mechanisms 14, further reducing energy consumption and reducing the cost of double-layer drying and shaping of the fabric, 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 a partition plate in the prior art.

[0033] Refer Figure 3 to Figure 4 As shown, the guiding member 123 includes: a wind guiding plate 1231 disposed on the inner wall of the housing 11 and extending obliquely with respect to the axis of the housing 11, and a side plate 1232 constructed at the extending end of the wind guiding plate 1231 and turning and extending toward the inner wall of the housing 11. The air supply assembly 122 sucks the hot air in the hot air mechanism 14 and sucks the hot air into the air duct 111, so that during the process of the hot air flowing in a swirling direction in the air duct 111, the two sets of side plates 1232 can evenly divide the hot air flowing in a swirling direction in the air duct 111 into two hot air streams, and cooperate with the wind guiding plate 1231 to guide the two hot air streams along Figure 4 two opposite directions indicated by arrows N1 and N2 in the figure to be uniformly sent into the first air outlet mechanism 13a and the second air outlet mechanism 13b through the air outlet 1111.

[0034] Furthermore, refer Figure 4As shown, the extension direction formed by the air guide plate 1231 and the extension direction formed by the side plate 1232 form an angle α that is tangent to the swirling flow direction of the hot gas in the air guide duct 111. The angle α is greater than 0° and less than 180°. When the position of the side plate 1232 remains unchanged and the angle α is larger, the distance between the air guide plate 1231 and the air supply component 122 is smaller, and the space of the air guide duct 111 is also smaller, resulting in a reduction in the flow rate of hot gas that the air guide duct 111 can accommodate. This reduces the flow rate of hot gas supplied to the first air outlet mechanism 13a and the second air outlet mechanism 13b, thus reducing the drying and shaping effect and drying efficiency of the textile. When the position of the side plate 1232 remains unchanged and the angle α is smaller, the distance between the air guide plate 1231 and the air supply component 122 is larger, and the space of the air guide duct 111 formed by the air guide plate 1231 is also larger, resulting in an increase in the flow rate of hot gas that the air guide duct 111 can accommodate. This reduces the flow rate of hot gas supplied to the first air outlet mechanism 13a and the second air outlet mechanism 13b, thus reducing the drying and shaping effect and drying efficiency of the textile. The increased flow rate of hot gas supplied by the first air outlet mechanism 13a and the second air outlet mechanism 13b improves the drying and setting effect and drying efficiency of the textiles. When the position of the guide plate 1231 remains unchanged, a larger angle α results in less airflow from the side plate 1232 to the swirling hot gas within the air duct 111, thus reducing the drying and setting effect and drying efficiency of the textiles. Conversely, a smaller angle α results in more airflow from the side plate 1232 to the swirling hot gas within the air duct 111, thereby increasing the flow rate of hot gas supplied by the first air outlet mechanism 13a and the second air outlet mechanism 13b, thus improving the drying and setting effect and drying efficiency of the textiles. Therefore, in practical use, the flow rate of hot gas that the air duct 111 can accommodate and the flow rate of hot gas that is separated can be adjusted by setting the angle α.

[0035] Specifically, refer to Figure 5 As shown, the guide member 123 includes: a first guide member 123a and a second guide member 123b; the first guide member 123a includes: a first air guide plate 1231a and a first side plate 1232a; the second guide member 123b includes: a second air guide plate 1231b and a second side plate 1232b; the first air guide plate 1231a and the second air guide plate 1231b are formed symmetrically in opposite directions around the air supply assembly 122, and the first side plate 1232a and the second side plate 1232b are formed symmetrically in opposite directions around the air supply assembly 122; the air outlet 1111 includes: a supply outlet for hot gas in the air supply duct 111 formed between the first air guide plate 1231a and the second side plate 1232b along a first direction (e.g., Figure 5 The first air outlet 1111a, which is gradually expanding in the direction indicated by the middle arrow N2, delivers hot gas from the air supply duct 111 formed between the second air guide plate 1231b and the first side plate 1232a in a second direction opposite to the first direction (as shown by the middle arrow N2). Figure 5It is sent out in the direction indicated by the arrow N1 in the figure and forms a second air outlet 1111b with a gradually expanding shape. Through the second side plate 1232b and the first side plate 1232a, the hot gas flowing in a swirling direction in the air duct 111 can be evenly divided into two hot gases, and the first air guide plate 1231a and the second air guide plate 1231b are coordinated to make the two hot gases pass through the first air outlet 1111a and the second air outlet 1111b in the first direction and the second direction respectively and are sent out in a diffused state, and are respectively sent into the second air outlet mechanism 13b and the first air outlet mechanism 13a. And the air duct 111 provided with the first air outlet 1111a and the second air outlet 1111b with a gradually expanding shape is shorter in the vertical length and smaller in volume compared with the fan air duct in the prior art, and is beneficial to reducing the wind noise.

[0036] It should be noted that the shapes of the first air guide plate 1231a and the second air guide plate 1231b can also be set as the arc shapes shown in Figure 6 The shapes of the first side plate 1232a and the second side plate 1232b can also be set as the arc shapes shown by the dotted lines in Figure 6 (that is, the first first side plate 1232a', the second second side plate 1232b'), or set as a plate body formed by a combination of a linear shape and an arc shape, as long as it can guide the two hot gases to be evenly sent out in two opposite vertical directions respectively. In addition, when the shapes of the first air guide plate 1231a and the second air guide plate 1231b are the arc shapes shown in Figure 6 the included angle α is formed by the tangent D of the arc-shaped first air guide plate 1231a and the extending direction of the first side plate 1232a.

[0037] Refer to Figure 2 , Figure 4 and Figure 8As shown, the air supply component 122 includes: a driving unit 1221 disposed on the outer wall of the housing 11 on the side opposite to the hot air mechanism 14, and a turbine 1222 coaxially disposed at the driving end included in the driving unit 1221 and formed in the air duct 111; the driving unit 1221 drives the turbine 1222 to rotate to suck the hot gas in the hot air mechanism 14 and guide the hot gas to flow in a swirling direction in the air duct 111. The driving end of the driving unit 1221 drives the turbine 1222 to rotate to suck the hot gas in the hot air mechanism 14 into the air duct 111. The rotation of the turbine 1222 drives the hot gas to flow in a swirling direction in the air duct 111. The rotation direction of the turbine 1222 determines the swirling flow direction of the hot gas in the air duct 111. The turbine 1222 converts the mechanical energy transmitted by the driving unit 1221 into a force for applying swirling flow to the hot gas through rotation, increases the pressure of the hot gas in the air duct 111 to accelerate the flow of the hot gas in the air duct 111, and tangentially contacts the swirling hot gas through the guiding member 123 to guide the hot gas to be evenly sent into the second air outlet mechanism 13b and the first air outlet mechanism 13a from the air duct 111 through the first air outlet 1111a and the second air outlet 1111b respectively.

[0038] In this embodiment, optionally, the fan unit can be configured as a centrifugal fan, the driving unit 1221 can be configured as a three-phase AC motor, and the three-phase AC motor can be independently adjusted by a control system (not shown) to drive the rotation speed of the turbine 1222. The control system is an inverter for controlling the rotation of the fan unit and a main control unit for controlling the inverter. The main control unit can be a PLC, an industrial control computer or a single-chip microcomputer, so as to adjust the flow rate of the hot gas blown by the first air outlet mechanism 13a and the second air outlet mechanism 13b to the textile. It should be noted that the turbine 1222 can be components such as an impeller and a blade, as long as it can suck the hot gas and make it flow in a swirling direction in the air duct 111.

The first air outlet pipe 1311 and the third air outlet pipe 1331 eject hot gas downward in a vertical or approximately vertical direction (i.e., Figure 2 the direction indicated by arrow C in the figure), and the second air outlet pipe 1321 and the fourth air outlet pipe 1341 eject hot gas upward in a vertical or approximately vertical direction (i.e., Figure 2 the direction indicated by arrow C' in the figure).

[0040] Refer to Figure 2 , Figure 7 and <XXXXXX>As shown, the first sub-tube group 151, the second sub-tube group 152, the third sub-tube group 153 and the fourth sub-tube group 154 all include a plurality of air guide openings 1531 corresponding to and communicating with the air outlet pipe, and a detachable connection is formed between the air outlet pipe and the air guide openings 1531. Specifically, the first sub-tube group 151 and the second sub-tube group 152 can be detachably connected to the first air outlet pipe group 131 and the second air outlet pipe group 132 respectively by means of snap connection, and the third sub-tube group 153 and the fourth sub-tube group 154 can be detachably connected to the third air outlet pipe group 133 and the fourth air outlet pipe group 134 respectively by means of snap connection, or other means (such as the connection method of bolt components) can also be used to achieve detachable connection, which will not be exemplified here one by one. It can be understood that by detachably connecting the first sub-tube group 151 and the second sub-tube group 152 to the first air outlet pipe group 131 and the second air outlet pipe group 132 respectively, and the third sub-tube group 153 and the fourth sub-tube group 154 to the third air outlet pipe group 133 and the fourth air outlet pipe group 134 respectively, it is convenient to disassemble, install, replace and clean the first air outlet mechanism 13a and the second air outlet mechanism 13b respectively, so as to facilitate the maintenance personnel to detect or repair the first air outlet mechanism 13a and the second air outlet mechanism 13b.

[0041] As shown Figure 2 shown, the textile is placed between the first air outlet pipe group 131 and the second air outlet pipe group 132, and the textile is placed between the third air outlet pipe group 133 and the fourth air outlet pipe group 134, and the hot gas is evenly sprayed downward along the direction shown by arrow C and upward along the direction shown by arrow C' in Figure 2 as shown to the textile for convective heating of the textile, so that the hot gas dries the textile more evenly, and finally improves the drying and shaping effect of the textile. Among them, the temperature of the hot gas ejected from the air outlet holes 1330 is generally within the range of 120 - 235°C. Exemplarily, for cotton textiles, the temperature of the hot gas ejected from the first air outlet pipe group 131, the second air outlet pipe group 132, the third air outlet pipe group 133 and the fourth air outlet pipe group 134 is generally within the range of 120 - 160°C; for chemical fiber textiles, the temperature of the hot gas ejected from the first air outlet pipe group 131, the second air outlet pipe group 132, the third air outlet pipe group 133 and the fourth air outlet pipe group 134 is generally within the range of 200 - 235°C.

[0042] As shown Figure 2 with Figure 8As shown, the air chamber 110 includes: a first air duct 1121 for the hot gas in the air supply chamber 110 to flow to the first sub-tube group 151, a second air duct 1122 for the hot gas in the air supply chamber 110 to flow to the second sub-tube group 152, a third air duct 1123 for the hot gas in the air supply chamber 110 to flow to the third sub-tube group 153, and a fourth air duct 1124 for the hot gas in the air supply chamber 110 to flow to the fourth sub-tube group 154; regulating air valves are provided inside the first air duct 1121, the second air duct 1122, the third air duct 1123 and the fourth air duct 1124 along the transverse length direction of the air chamber 110 to regulate the air volume of the hot gas respectively sent into the first sub-tube group 151, the second sub-tube group 152, the third sub-tube group 153 and the fourth sub-tube group 154. When the driving end of the driving unit 1221 drives the turbine 1222 to rotate to suck the hot gas in the hot air mechanism 14 into the guide air duct 111, the rotation of the turbine 1222 drives the hot gas to flow in a swirling direction in the guide air duct 111, and is evenly sent into the first air duct 1121 and the second air duct 1122 through the first air outlet 1111a, and evenly sent into the third air duct 1123 and the fourth air duct 1124 through the second air outlet 1111b.

[0043] Refer Figure 4 to Figure 8As shown, the regulating damper includes: a first regulating plate 1131 formed in the first air duct 1121 and rotatably connected to the housing 11 to regulate the flow of hot gas into the first air duct 1121; a second regulating plate 1132 formed in the second air duct 1122 and rotatably connected to the housing 11 to regulate the flow of hot gas into the second air duct 1122; a third regulating plate 1133 formed in the third air duct 1123 and rotatably connected to the housing 11 to regulate the flow of hot gas into the third air duct 1123; and a fourth regulating plate 1134 formed in the fourth air duct 1124 and rotatably connected to the housing 11 to regulate the flow of hot gas into the fourth air duct 1124. The flow of hot gas entering the first air duct 1121 and the second air duct 1122 is regulated by rotating the first regulating plate 1131 and the second regulating plate 1132, respectively; and the flow of hot gas entering the third air duct 1123 and the fourth regulating plate 1134 is regulated by rotating the third regulating plate 1133 and the fourth regulating plate 1134, respectively. The volume of hot gas entering the first air duct 1121 and the second air duct 1122 is related to the rotation angle of the first regulating plate 1131 and the second regulating plate 1132. The volume of hot gas entering the third air duct 1123 and the fourth air duct 1124 is related to the rotation angle of the third regulating plate 1133 and the fourth regulating plate 1134. When the first regulating plate 1131, the second regulating plate 1132, the third regulating plate 1133, and the fourth regulating plate 1134 are in a horizontal state (not shown), the volume of hot gas entering the first sub-pipe group 151, the second sub-pipe group 152, the third sub-pipe group 153, and the fourth sub-pipe group 154 ​​respectively reaches its maximum. When the first regulating plate 1131, the second regulating plate 1132, the third regulating plate 1133, and the fourth regulating plate 1134 rotates from a horizontal state to an inclined state, such as Figure 8 As shown, the airflow of hot gas entering the first sub-pipe group 151, second sub-pipe group 152, third sub-pipe group 153, and fourth sub-pipe group 154 ​​from the first air duct 1121, second air duct 1122, third air duct 1123, and fourth air duct 1124 is reduced respectively. When the first adjusting plate 1131, second adjusting plate 1132, third adjusting plate 1133, and fourth adjusting plate 1134 rotates from the inclined state to the vertical state (not shown), the airflow of hot gas entering the first sub-pipe group 151, second sub-pipe group 152, third sub-pipe group 153, and fourth sub-pipe group 154 ​​from the first air duct 1121, second air duct 1122, third air duct 1123, and fourth air duct 1124 is greatly reduced, and the airflow of hot gas entering the first sub-pipe group 151, second sub-pipe group 152, third sub-pipe group 153, and fourth sub-pipe group 154 ​​is minimized at this time. Therefore, in actual use, the hot gas flow rate can be adjusted according to the different types of textiles and the different setting processes required to ensure the drying and setting effect of the textiles.

[0044] Specifically, referring Figure 1 to Figure 2 as shown, the hot air mechanism 14 includes: a combustion chamber 141, a heating source for generating hot gas within the combustion chamber 141, and a hot air duct 142 connecting the combustion chamber 141 and the housing 11. Preferably, the heating source is configured as a burner 143 detachably provided on the side wall of the combustion chamber 141, and the nozzle (not shown) of the burner 143 extends into the combustion chamber 141. The burner 143 forms hot gas within the combustion chamber 141 by burning gas (e.g., natural gas). The combustion chamber 141 is configured with ventilation holes (not labeled) for laterally sucking air, and the ventilation holes (not labeled) are covered with a filter net 144. External air is introduced into the combustion chamber 141 in the direction shown by the arrow Q in Figure 2 the figure. The hot gas generated by the heating of the burner 143 is mixed with the introduced external air in a certain proportion to obtain the hot gas with the best drying effect on the fabric. Under the action of the driving unit 1221 driving the turbine 1222 to rotate, the hot gas is transported from the combustion chamber 141 through the hot air duct 142 to the air chamber 110, and further transported to the first air outlet mechanism 13a and the second air outlet mechanism 13b, so that the first air outlet mechanism 13a and the second air outlet mechanism 13b spray hot gas to dry and shape the fabric. An air guiding cylinder 1001 formed in the air chamber 110 is provided inside the housing 11, and the air guiding cylinder 1001 is connected to the hot air duct 142 to guide the hot gas to the turbine 1222. The driving unit 1221 driving the turbine 1222 to rotate can guide the hot gas in the hot air duct 142 to the turbine 1222 through the air guiding cylinder 1001, so as to further suck the hot gas into the air chamber 110 through the turbine 1222.

[0045] Based on the technical solution of a double - outlet compound shaping device 1 disclosed in the foregoing embodiments, this embodiment also discloses a double - layer stenter 10.

[0046] Referring Figure 1 to Figure 9As shown, in this embodiment, the double-layer stretching and setting device 10 includes: a housing 101; at least one dual-outlet compound setting device 1 as disclosed in the above embodiment, axially disposed within the housing 101; a first adjustment mechanism 104a disposed within the housing 101 and formed between the first air outlet pipe group 131 and the second air outlet pipe group 132 for stretching the textile; and a second adjustment mechanism 104b formed between the third air outlet pipe group 133 and the fourth air outlet pipe group 134 for stretching the textile. The first adjustment mechanism 104a and the second adjustment mechanism 104b are used to stretch the textile. It should be noted that the housing 101 can be a frame, board, or other supporting structure, as long as it can support the first adjustment mechanism 104a, the second adjustment mechanism 104b, and the dual-outlet compound setting device 1. The double-layer tenter frame 10, equipped with a dual-outlet double-stage setting device 1, can perform double drying and setting on two layers of textile fabric arranged vertically. It also reduces the vertical height of the double-layer tenter frame 10, making its structure more compact and reducing space requirements. Furthermore, the double-layer tenter frame 10 provides hot air to the first air outlet mechanism 13a and the second air outlet mechanism 13b through a set of hot air mechanisms 14, further reducing energy consumption and lowering the production and manufacturing costs of double drying and setting on textile fabrics. This overcomes the problems of large space occupation, high energy consumption, and uneven heat distribution within a single double-layer tenter frame 10 caused by the partition plates in existing double-outlet double-stage tenter frames, which consist of two vertically arranged setting machines separated by partition plates.

[0047] like Figure 1 , Figures 9 to 12 As shown, the double-layer tenter frame 10 includes at least two double-outlet duplex tenter frames 1, and two adjacent double-outlet duplex tenter frames 1 are both along the longitudinal direction of the housing 11 ( Figure 1 (In the direction indicated by the double-headed arrow X) sidewall splicing. The hot air mechanism 14 connects to at least two horizontally arranged housings 11 and is connected to the hot air pipe 142. The two horizontally arranged housings 11 are isolated from each other and are isolated from each other in the horizontal direction but are connected to the hot air pipe 142 together. Each housing 11 is independently provided with a dual-outlet air supply mechanism 12, so that the hot gas drawn into the air chamber 110 by the dual-outlet air supply mechanism 12 will not interfere with each other during the process of being sent into the first air outlet mechanism 13a and the second air outlet mechanism 13b, so as to avoid affecting the uniformity of the hot gas being sent into the first air outlet mechanism 13a and the second air outlet mechanism 13b, and to facilitate the heat being concentrated on the textile being stretched and set.

[0048] The hot air duct 142 is configured with multiple hot air distribution ducts 1421 communicating with the air chambers 110, or the hot air duct 142 is configured with multiple hot air distribution openings 1412 communicating with the air chambers 110. As Figure 12 shown, the hot air duct 142 can be configured with hot air distribution ducts 1421 for delivering hot gas to the air chambers 110. The number of the hot air distribution ducts 1421 is the same as that of the double - outlet air supply mechanisms 12. The double - outlet air supply mechanisms 12 suck the hot gas in the hot air duct 142 and guide it through the air guiding cylinder 1001 to the turbine 1222, so as to further suck the hot gas into the air chambers 110 through the turbine 1222. As Figure 11 shown, the hot air duct 142 can also be configured with hot air distribution openings 1412 for delivering hot gas to the air chambers 110. The number of the hot air distribution openings 1412 is the same as the total number of the double - outlet air supply mechanisms 12. The double - outlet air supply mechanisms 12 suck the hot gas in the hot air duct 142 and guide it through the air guiding cylinder 1001 to the turbine 1222, so as to further suck the hot gas into and respectively deliver it to the air chambers 110 through the turbine 1222.

[0049] As Figure 9 shown, the hot air mechanism 14 communicates with an even number of horizontally - arranged housings 11, and most preferably two housings 11. The guiding members 123 in adjacent double - outlet compound setting devices 1 are horizontally mirror - arranged with respect to the splicing surface formed by the two double - outlet compound setting devices 1. Adjacent double - outlet compound setting devices 1 are spliced along the longitudinal side walls of the box body 101 ( Figure 13 in the direction of the double - headed arrow X shown in Figure 9 ), and form a splicing surface V (as shown by the dashed line V in Figure 13 ). The guiding members 123 in adjacent double - outlet compound setting devices 1 in the same double - layer stenter setting equipment 10 are horizontally mirror - arranged with respect to the splicing surface V. The splicing surface V is perpendicular to the horizontal plane.

[0050] Refer Figure 2 to Figure 9 and Figure 10As shown, the double-layer stenter 10 further includes: fixed brackets 105 disposed on both sides of the first air outlet mechanism 13a and the second air outlet mechanism 13b along the longitudinal direction of the box body 101. The first amplitude adjustment mechanism 104a includes: two first amplitude adjustment members 1041 disposed horizontally on the fixed brackets 105, and the second amplitude adjustment mechanism 104b includes: two second amplitude adjustment members 1042 disposed horizontally on the fixed brackets 105; the two first amplitude adjustment members 1041 are used to stretch the textile when approaching each other, and the two second amplitude adjustment members 1042 are used to stretch the textile when approaching each other. The two first amplitude adjustment members 1041 achieve the purpose of stretching the textile during the process of approaching and separating from each other, and cooperate with the hot gas ejected from the air outlet holes 1330 in the first air outlet pipe group 131 and the second air outlet pipe group 132 to heat the textile. The two second amplitude adjustment members 1042 achieve the purpose of stretching the textile during the process of approaching and separating from each other, and cooperate with the hot gas ejected from the air outlet holes 1330 in the third air outlet pipe group 133 and the fourth air outlet pipe group 134 to heat the textile, so as to achieve continuous and efficient stretching and setting treatment of the textile.

[0051] Refer Figure 9 to Figure 10 and Figure 11 As shown, the double-layer stenter 10 further includes: moisture discharge holes 1011 formed on the top of the box body 101, and a moisture extraction pipe 103 connected to the moisture discharge holes 1011 and disposed on the top of the box body 101. The moisture discharge holes 1011 are formed in the box body 101 for the circulation of the moisture generated during the drying and setting process of the textile by the double-outlet double-type setting device 1. And since the double-outlet double-type setting device 1 will cause the temperature inside the box body 101 to continuously rise during operation, the moisture generated inside the box body 101 carries high heat. Therefore, it is necessary to extract the moisture with high heat and mixed with oil fume and lint through the moisture extraction pipe 103 through the moisture discharge holes 1011 under the action of the centrifugal fan 106 connected to the moisture extraction pipe 103, and discharge it into the external air, and always keep the inside of the box body 101 in a negative pressure state to avoid the fire and explosion accidents caused by excessive accumulation of flammable gases in the box body 101. 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 stretching and setting process at high temperature.

[0052] The moisture extraction pipe 103 can be configured as shown in Figure 10 on the outer top of the box body 101 to form an external moisture extraction pipe 103. Multiple double-layer stenters 10 form a double-layer stenter system 100 and splice all the moisture extraction pipes 103 horizontally into an integral pipe 103', as shown in Figure 14 and Figure 15As shown, the centrifugal fan 106 is arranged at the end of the overall pipeline 103', and under the action of the centrifugal fan 106, the moisture in the box body 101 is pumped out into the external air; alternatively, the dehumidification pipeline 103 on the outer top of the box body 101 can be independently connected to a centrifugal fan 106 to pump out the moisture in the box body 101 into the external air under the action of the centrifugal fan 106, so as to keep the box body 101 in a negative pressure state all the time.

[0053] Based on the technical solutions of any one of the double-width stenter devices 10 disclosed in the foregoing embodiments and their reasonable combinations, the present embodiment also discloses a double-width stenter system 100.

[0054] Refer Figure 15 As shown, in the present embodiment, the double-width stenter system 100 includes: a fabric feeding unit 20, at least one double-width stenter device 10 as disclosed in the foregoing embodiments, and a fabric discharging unit 30; the double-width stenter device 10 is arranged between the fabric feeding unit 20 and the fabric discharging unit 30. Two layers of textiles arranged vertically up and down are fed into the double-width stenter device 10 through the fabric feeding unit 20 along the Figure 14 direction shown by the Y axis in the figure for drying, and are subjected to width setting through the first width adjusting mechanism 104a and the second width adjusting mechanism 104b during the drying process. Finally, the textiles conveyed out of the double-width stenter device 10 are arranged neatly by the fabric discharging unit 30 to complete the whole process. The fabric feeding unit 20 and the fabric discharging unit 30 are both prior arts, so they will not be elaborated here. Refer Figure 10 As shown, the double-width stenter system 100 includes at least two double-width stenter devices 10, and two adjacent double-width stenter devices 10 are spliced along the longitudinal side wall of the box body 101; the number of box bodies 101 can be 6 to 14 or even more.

[0055] When the textiles enter the double-width stenter device 10, they can be successively subjected to width setting through the double-width stenter device 10, so as to improve the width setting efficiency of the textiles. The gradually increasing temperature inside the box body 101 will be transferred to the adjacent box body 101 due to the heat transfer performance of the steel plate (the box body 101 is preferably made of steel plate material), so as to preheat the adjacent box body 101 to improve the heat utilization rate. Moreover, the double-width stenter devices 10 included in the double-width stenter system 100 of the present embodiment reduce the vertical height and the volume, so as to reduce the heat dispersion, so that the heat of the hot gas generated by the burner can be concentrated in a relatively small space, further reducing the energy consumption and overcoming the problem in the prior art that the large energy consumption of the stenter machine leads to a large processing cost of the textiles.

[0056] Exemplarily, in some embodiments, the hot air mechanisms 14 of the double - outlet compound setting devices 1 in each double - layer stenter setting device 10 are on the same side and have the same air supply direction, all along the Figure 14 or Figure 16 The direction of air supply shown by the arrow X1 in the figure, and the dehumidifying pipes 103 in different double - layer stenter setting devices 10 are all located on the same side of the top of the box body 101. The dehumidifying pipe 103 can be configured as the outer top of the box body 101 as shown in Figure 10 . Refer to Figure 14 and Figure 15 . As shown, the dehumidifying pipes 103 of multiple double - layer stenter setting devices 10 can be connected end - to - end to form an integral pipe 103'. A centrifugal fan 106 is configured at the end of the integral pipe 103' to exhaust the moisture in the box body 101 under the action of the centrifugal fan 106; or, refer to Figure 16 and Figure 17 . As shown, the dehumidifying pipes 103 of multiple double - layer stenter setting devices 10 are all connected to a converging exhaust pipe 107. The centrifugal fan 106 is configured at the end of the converging exhaust pipe 107 to extract the moisture in the box body 101 into the converging exhaust pipe 107 through the dehumidifying pipe 103, and then exhaust the moisture in the box body 101 to the outside air through the converging exhaust pipe 107. In addition, the guiding members 123 in the double - outlet compound setting devices 1 included in adjacent double - layer stenter setting devices 10 are arranged in a vertical mirror image with respect to the splicing surface M formed by the two double - layer stenter setting devices 10. The adjacent double - layer stenter setting devices 10 are spliced along the longitudinal side walls of the box body 101 and form a splicing surface M (as shown by the dotted line M in Figure 18 ), and the guiding members 123 in the adjacent double - outlet compound setting devices 1 included in the same double - layer stenter setting device 10 are arranged in a vertical mirror image with respect to the splicing surface M. The splicing surface M is perpendicular to the horizontal plane.

[0057] Refer to Figure 19 and Figure 20 . As shown, exemplarily, in some embodiments, the air supply directions of the hot air mechanisms 14 in adjacent double - layer stenter setting devices 10 can also be configured to be periodically staggered. The air supply directions of the hot air mechanisms 14 in adjacent double - layer stenter setting devices 10 are staggered along the Figure 19 directions shown by the arrow Xl and the arrow X2 in the figure. The dehumidifying pipes 103 of multiple double - layer stenter setting devices 10 are all connected to a converging exhaust pipe 107 to improve the uniformity of the temperature distribution in the double - layer stenter setting system 100.

[0058] Based on the double-layer tenter frame system 100 disclosed in the foregoing embodiments, this embodiment also discloses the application of the double-layer tenter frame system 100. The double-layer tenter frame system 1000, as disclosed in the above embodiments, is used to tenter and set fabrics, including woven fabrics, knitted fabrics, nonwoven fabrics, non-woven materials, fur and leather, and composite fabrics.
