Description

Technical Field

[0001] This utility model relates to the field of textile setting technology, specifically to a fabric exhaust cooling device for a tenter frame. Background Technology

[0002] After the fabric has been stretched and set at high temperature, excess heat needs to be dissipated in time. If it is not cooled sufficiently before being wound up, creases that are difficult to eliminate will easily appear on the fabric surface, affecting the smoothness of the fabric surface. If it is a colored fabric that has been set at high temperature, the residual heat on the fabric surface will accumulate when it is not cooled enough, which may lead to a decrease in color stability after winding up, affecting product quality.

[0003] Existing tenter frame cooling devices mainly include two types: air-cooled and water-cooled. Air-cooled devices typically use air ducts to cool the fabric surface, but if hot air from around the tenter frame is drawn in, the cooling efficiency is significantly reduced. Water-cooled devices use water-cooled rollers to conduct heat to the fabric surface, which is effective to some extent, but the cooling capacity of a single roller is limited. Installing multiple rollers increases costs, and a cooling water circulation system is required, resulting in higher investment and maintenance costs. Utility Model Content

[0004] The technical problem to be solved by this utility model is to address the shortcomings of the existing technology by providing a fabric exhaust cooling device for a stenter that can quickly remove heat from the surface of the fabric and minimize the decrease in fabric color stability.

[0005] The technical problem to be solved by this utility model is achieved through the following technical solution: a fabric exhaust cooling device for a tenter frame, which is arranged above and below the fabric exit guide rail of the tenter frame, including; The air blowing device includes an air inlet pipe, a blower I, and a blower pipe. The blower I is installed at the air inlet end of the air inlet pipe, and the blower pipe is installed at the air outlet end of the air inlet pipe. The air outlet end of the blower pipe is located directly above the fabric exit area guide rail of the tenter frame and is directly facing the fabric on the fabric exit area guide rail of the tenter frame, so as to air-cool the fabric. The suction device includes a suction hood, an intermediate bend pipe, a fan connecting pipe, and a fan II. The air inlet of the suction hood is located directly below the fabric output guide rail of the tenter frame. The air outlet of the suction hood is connected to the intermediate bend pipe, the intermediate bend pipe is connected to the fan connecting pipe, and the fan connecting pipe is connected to the fan II. Fan II draws air from the fabric on the guide rail of the stenter's output area through the suction hood, thereby extracting hot air from the vicinity of the fabric.

[0006] The technical problem to be solved by this utility model can also be achieved through the following technical solution: the fabric exhaust cooling device of the tenter frame described above also includes a frame, the air inlet pipe is installed on the top of the frame, and the fan I is installed on the middle of the frame.

[0007] The technical problem to be solved by this utility model can also be achieved through the following technical solution: the above-mentioned fabric exhaust cooling device for a tenter frame, wherein the fan I is a centrifugal fan.

[0008] The technical problem to be solved by this utility model can also be achieved through the following technical solution: the fabric exhaust cooling device of the tenter frame described above, wherein the bottom of the intermediate bend is connected to a bracket for supporting the intermediate bend by bolts, and the bottom of the bracket is fixed to the ground by expansion bolts.

[0009] The technical problem to be solved by this utility model can also be achieved through the following technical solution: the above-mentioned fabric exhaust cooling device for a tenter frame, wherein the fan II is an exhaust fan.

[0010] The technical problem to be solved by this utility model can also be achieved through the following technical solution: the fabric exhaust cooling device of the tenter frame described above, wherein the cross-sectional area of ​​the air inlet end of the exhaust hood is larger than the cross-sectional area of ​​the air outlet end of the blower pipe.

[0011] Compared with the prior art, the beneficial technical effects of this utility model are: (1) A top-down directional convection field is constructed by the blowing device above the fabric exit guide rail and the suction device below the tenter frame. The blowing pipe forces the cooling air to the high-temperature fabric surface, directly taking away some of the heat. At the same time, the suction hood, under the action of the exhaust fan, immediately and quickly removes the heated air and residual heat from the fabric surface, avoiding the stagnation and backflow of hot air around the fabric surface, forming an efficient heat exchange channel. This achieves rapid and uniform forced cooling of the shaped fabric, avoiding the problem of residual heat accumulation on the fabric surface when the cooling is insufficient, which may lead to a decrease in color stability after winding.

[0012] (2) The fabric exhaust cooling device does not require a complex and expensive water circulation system, water-cooled roller and corresponding water treatment facilities. It only uses conventional components such as fans, air ducts and exhaust hoods, which greatly reduces the initial investment cost and the later maintenance and operation cost of the equipment. It has a simple structure and low manufacturing and installation costs.

[0013] (3) The suction device is directly fixed to the ground by brackets and expansion bolts, without the need for complex welding or permanent connection with the main unit. This modular installation method is not only easy to install and disassemble, saving installation time and labor costs, but also makes the device flexible to adapt to a variety of existing models of tenter frame machines, making it very convenient to modify and upgrade.

[0014] (4) The air intake area of ​​the suction hood is designed to be no less than the air blowing area of ​​the air blowing pipe, which ensures that all the hot air generated in the air blowing area can be captured and discharged without any omission, effectively avoiding the spread of heat pollution in the workshop and significantly improving the working environment. In addition, compared with the water cooling system, which consumes water resources and electricity, the energy consumption of this device is only two fans, which is lower and meets the requirements of green production, thus indirectly achieving energy saving.

[0017] The specific technical solutions of this utility model are further described below with reference to the accompanying drawings, so as to enable those skilled in the art to further understand this utility model, without constituting a limitation on its rights.

[0018] Example 1, referring to Figure 1-3 A fabric exhaust cooling device for a tenter frame, which is arranged above and below the fabric exit guide rail 1 of the tenter frame, includes: The air blowing device includes an air inlet pipe 2, a fan I3, and an air blowing pipe 4. The fan I3 is installed on the air inlet end of the air inlet pipe 2. The size and specifications of the air inlet pipe 2 can be selected according to the usage requirements. The fan I3 is a centrifugal fan. The air blowing pipe 4 is installed on the air outlet end of the air inlet pipe 2. The air outlet end of the air blowing pipe 4 is located directly above the fabric output area guide rail 1 of the tenter frame and is directly facing the fabric 5 on the fabric output area guide rail 1 of the tenter frame, so as to air-cool the fabric 5. The suction device includes a suction hood 6, an intermediate bend pipe 7, a fan connecting pipe 8, and a fan II 9. The air inlet of the suction hood 6 is located directly below the fabric output guide rail 1 of the tenter frame. The longitudinal section of the suction hood 6 is an inverted trapezoidal shape, i.e., larger at the top and smaller at the bottom. The cross-sectional area of ​​the air inlet of the suction hood 6 is larger than the cross-sectional area of ​​the air outlet of the blower pipe 4. Its design purpose is to absorb as much hot air as possible from the blower. The air outlet of the suction hood 6 is connected to the intermediate bend pipe 7, which is connected to the fan connecting pipe 8. The diameters of the intermediate bend pipe 7 and the fan connecting pipe 8 can be selected according to the usage requirements. The fan connecting pipe 8 is connected to the fan II 9, which is an exhaust fan that blows out the sucked hot air. Fan II 9 draws air from the fabric 5 on the fabric exit guide rail 1 of the tenter frame through the suction hood 6, thereby drawing out the hot air near the fabric 5.

[0019] In Example 1, the fabric 5 is blown by a blower and the hot air after blowing is absorbed by a suction device. Later, a dust collection pipe can be connected to the exhaust end of the exhaust fan for further filtration. Compared with traditional water circulation systems, water-cooled rollers and corresponding water treatment facilities, it only uses conventional components such as fans, air ducts and suction hoods 6, which greatly reduces the initial investment cost and the later maintenance and operation cost of the equipment, and the effect is better.

[0020] Example 2, the fabric exhaust cooling device of the tenter frame described in Example 1, further includes a frame 10, which can be formed by overlapping and welding profiles. The air inlet pipe 2 is installed on the top of the frame 10, and the fan I3 is installed on the middle of the frame 10.

[0021] Example 3, the fabric exhaust cooling device of the tenter frame described in Example 1, wherein the bottom of the intermediate bend 7 is connected by bolts to a bracket 11 for supporting the intermediate bend 7. The bracket 11 may be a columnar structure, and the bottom of the bracket 11 is fixed to the ground by expansion bolts 12.

[0022] The operating principle of the fabric exhaust cooling device of the tenter frame in Examples 1-3 is as follows: Start the fan I3, which pumps ambient air or cooling air into the air inlet pipe 2, and finally blows it downward through the air blowing pipe 4 to form a uniform air curtain covering the width of the fabric. This air curtain directly impacts the surface of the fabric that has just been shaped and is in a high-temperature state, and initially removes a large amount of sensible heat from the fabric surface through forced convection. At the same time, the fan II 9 is started, which forms a stable negative pressure zone at the inlet of the suction hood 6. Since the air inlet area of ​​the suction hood 6 is larger than the air outlet area of ​​the blower pipe 4, and its inverted trapezoidal structure design can effectively expand the range of hot air capture, ensuring that all the hot air blown away by the blower pipe 4 above, as well as the hot air radiated and conducted from the fabric surface, is sucked in. The sucked-in hot exhaust gas is then forced to be transported to the designated outdoor emission point or the factory dust removal system by the exhaust fan through the intermediate bend pipe 7 and the fan connecting pipe 8. This combination of blowing and suction effectively avoids the "secondary heating" problem caused by the recirculation of hot air in traditional single air-cooling devices, and also overcomes the disadvantages of water-cooling systems, such as high cost and easy water stain pollution, thus achieving rapid, uniform and low-cost forced cooling of fabrics.
