Description

Technical Field

[0001] This utility model relates to fabric processing equipment, and more particularly to a self-drying and shaping machine that utilizes waste heat exhaust for self-circulation. Background Technology

[0002] Fabric setting is a common fabric processing step in the dyeing and finishing industry. It ensures the fabric has a stable width, guaranteeing its performance in subsequent printing and dyeing processes. Current fabric setting equipment is a setting machine, which uses a long setting chamber. Inside the chamber is a stretching and setting mechanism to hold the fabric stable on both sides. A hot air supply device is also installed. The fabric inlet end of the chamber has an infeed mechanism that guides the dyed or impregnated fabric onto the stretching and setting mechanism. The fabric outlet end has an outlet mechanism that folds and collects the stretched and set fabric. The hot air supply device can utilize a hot air chamber connected to the setting chamber, which is connected to the outside via a fan. The hot air chamber is heated by a radiator with steam or electric heaters, or directly by natural gas. The fan blows outside air into the hot air chamber for heating before it enters the setting chamber. The tenter frame mechanism employs two chains that move synchronously on opposite sides of the setting chamber, driven by motors and sprockets respectively. Fabric clamps or needle plates are installed on the chains to hold the fabric edges and tighten them. After dyeing or impregnation, the fabric is introduced into the tenter frame mechanism within the setting chamber by the fabric feeding mechanism. Hot air is blown into the setting chamber by a fan, and the tenter frame mechanism performs high-temperature setting and drying on the fabric moving within the chamber. After setting and drying, the fabric is folded and collected by the fabric exit mechanism at the exit end. The heated waste air is discharged into the air through an exhaust pipe and exhaust fan at the top of the setting chamber. However, because the fabric is directly stretched and shaped in a single layer in the sizing chamber, the sizing machine needs to have a long sizing chamber, sometimes up to 30 meters long, in order to dry the fabric at the exit end, thus occupying a large area. At the same time, the heated air temperature needs to be very high, and the airflow rate is also high to quickly dry the moisture in the fabric. This results in the exhaust hot air temperature after heating and sizing being very high, containing a large amount of heat. Directly discharging it into the air will cause heat loss and high energy consumption. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a self-drying and shaping machine with small footprint, low heat loss, low energy consumption, and self-circulation of waste heat exhaust.

[0004] To solve the above-mentioned technical problems, the technical solution of this utility model is: a self-drying and shaping machine that utilizes waste heat exhaust air for self-circulation. This self-drying and shaping machine includes a fabric feeding mechanism, a drying device, a shaping device, and a fabric discharging mechanism. The shaping device is equipped with a hot air supply device and a waste heat exhaust pipe. The waste heat exhaust pipe is connected to a waste heat pipe, which is connected to the drying device. The drying device is equipped with a waste gas discharge device. The fabric feeding mechanism is located at the fabric feeding end of the drying device, and the fabric discharging mechanism is located at the fabric discharging end of the shaping device. A fabric synchronous guide roller group is provided between the fabric discharging end of the drying device and the fabric feeding end of the shaping device.

[0005] As an improvement to the above technical solution, the drying device is located above the shaping device; the fabric inlet end of the drying device and the fabric outlet end of the shaping device are located at the same end of the self-drying and shaping machine.

[0006] As an improvement to the above technical solution, the drying device includes a drying oven disposed on the upper side of the shaping device, a fabric feeding mechanism disposed at the fabric feeding end of the drying oven, and a fabric guiding device disposed inside the drying oven; a spare hot air chamber disposed on the drying oven and connected to the drying oven, a circulating fan disposed inside the spare hot air chamber, and the spare hot air chamber connected to a waste hot air pipe.

[0007] As an improvement to the above technical solution, the shaping device includes a shaping chamber located below the oven, the shaping chamber being connected to a hot air supply device and a waste hot air discharge pipe, the fabric outlet mechanism being located at the fabric outlet end of the shaping chamber, the fabric inlet end of the oven and the fabric outlet end of the shaping chamber being located at the same end, the fabric synchronous guide roller group being located between the fabric outlet end of the oven and the fabric inlet end of the shaping chamber, and a stretching and shaping mechanism being provided in the shaping chamber.

[0008] As an improvement to the above technical solution, the hot air supply device includes a hot air chamber located at the lower part of the shaping chamber, the hot air chamber being connected to the shaping chamber, a hot air generator being installed inside the hot air chamber, an air inlet being installed on the hot air chamber, and an air intake fan being installed at the air inlet.

[0009] As an improvement to the above technical solution, the guiding device is at least two layers of guide rollers arranged vertically inside the drying oven or at least two layers of mesh belts installed by rotating rollers.

[0010] As an improvement to the above technical solution, the exhaust gas discharge device includes exhaust gas discharge pipes arranged sequentially along the length of the oven at the top of the oven, and each exhaust gas discharge pipe is connected to an exhaust gas discharge fan; the oven is provided with a spare hot air chamber connected to the oven, and a circulating fan is provided in the spare hot air chamber, which is connected to a waste hot air pipe.

[0011] As an improvement to the above technical solution, the exhaust end of the waste hot air pipe is provided with a heat exchange device for heating air, and the heat exchange device is connected to the waste hot air pipe.

[0012] As an improvement to the above technical solution, the waste heat duct is equipped with an air volume regulating device.

[0013] Because of the above-mentioned technical solution for the self-drying and setting machine that utilizes waste heat exhaust for self-circulation, the hot air supply device first heats up the air during operation. The heated air then enters the drying device through the waste hot air exhaust pipe and waste hot air duct. After dyeing or impregnation, the fabric is first introduced into the drying device by the fabric feeding mechanism, then guided into the setting device by the fabric synchronous guide roller group, and finally collected by the fabric output mechanism. The hot air supply device provides the setting device with high-temperature hot air for fabric setting and drying. After setting and drying, the temperature drops, and the waste hot air containing a large amount of heat enters the drying device through the waste hot air duct to pre-dry the fabric. After pre-drying the fabric, the exhaust gas is discharged through an exhaust gas discharge device. This combination of drying and setting devices allows for the setting and drying of the fabric in a shorter setting chamber, reducing the chamber length and significantly reducing the footprint of the setting machine. This invention first uses high-temperature, low-humidity air to set and dry the pre-dried fabric (which is hot and has low moisture content). Then, it uses hot air, which has cooled slightly after setting but still contains a lot of heat, to pre-dry the fabric (which is hot and has low moisture content), further reducing the exhaust gas temperature and heat content, resulting in low heat loss and low energy consumption. Furthermore, this invention can stretch the fabric width significantly more effectively than current setting machines, ensuring the correct fabric width. The fabric infeed and outfeed mechanisms are located on the same side, improving the convenience of infeed and outfeed operations, reducing manpower consumption, and increasing production efficiency.

Detailed Implementation

[0016] The exemplary embodiments of the present invention will now be described in detail with reference to the accompanying drawings. It should be noted that, in the drawings, the same reference numerals are assigned to components that are substantially the same in structure and function, and redundant descriptions of substantially the same components have been omitted to make the description more concise.

[0017] like Figure 1 As shown, a self-drying and shaping machine that utilizes waste heat exhaust is included. The machine comprises a fabric feeding mechanism 6, a drying device 34, a shaping device 35, and a fabric discharging mechanism 7. The shaping device 35 is equipped with a hot air supply device and a waste heat exhaust pipe 12. The waste heat exhaust pipe 12 is connected to a waste heat air pipe 10, which is connected to the drying device 34. The drying device 34 is equipped with a waste gas discharge device. The fabric feeding mechanism 6 is located at the fabric feeding end of the drying device 34, and the fabric discharging mechanism 7 is located at the fabric discharging end of the shaping device 35. A fabric synchronous guide roller group 8 is provided between the fabric discharging end of the drying device 34 and the fabric feeding end of the shaping device 35. During operation, the hot air supply device first heats up to provide high-temperature hot air. The high-temperature hot air enters the drying device through the waste hot air discharge pipe 12 and waste hot air pipe 10. After dyeing or impregnation, the fabric 9 is first introduced into the drying device 34 by the fabric feeding mechanism 6 for pre-drying. After pre-drying, it is then introduced into the setting device 35 by the fabric synchronous guide roller group 8 for drying and stretching. After drying and stretching, the fabric is then collected by the fabric exit mechanism 7. The high-temperature hot air first pre-dries the fabric 9 in the drying device 34 and then dries and stretches it. Afterwards, the hot air, which has decreased in temperature and contains a large amount of heat, enters the drying device 34 through the waste hot air pipe 10 to pre-dry the fabric 9. Afterwards, the waste gas is discharged through the waste gas discharge device.

[0018] like Figure 1 and 2As shown, the drying device 34 is located above the shaping device 35, which can greatly reduce the floor space of the equipment. A support platform 5 can be set between the drying device 34 and the shaping device 35 for the drying device 34, which facilitates the installation, operation and maintenance of the equipment. The fabric inlet end of the drying device 34 and the fabric outlet end of the shaping device 35 are located at the same end of the self-drying shaping machine. The fabric inlet mechanism 6 and the fabric outlet mechanism 7 are located at the same end of the self-drying shaping machine, which improves the convenience of fabric inlet and outlet operations.

[0019] like Figure 2 and 4As shown, the drying device 34 includes an oven 11 disposed on the upper side of the shaping device 35, a fabric feeding mechanism 6 disposed at the fabric feeding end of the oven 11, a fabric guiding device disposed inside the oven 11, a spare hot air chamber 2 disposed on the oven 11 and connected to the oven 11, a circulating fan 31 disposed inside the spare hot air chamber 2, the spare hot air chamber 2 being connected to a waste hot air pipe 10, and the outlet of the waste hot air pipe 10 being close to the inlet of the circulating fan 31, the hot air transmitted from the waste hot air pipe 10 being sprayed into the oven 11 by the circulating fan 31, and at the same time the high-temperature hot air inside the oven 11 being drawn and circulated into the oven 11 to dry the fabric. A heater 3 can also be installed in the backup hot air chamber 2. This heater 3 can be a commonly used type of heater in drying equipment, such as a natural gas direct-fired heater, or a heat transfer oil and steam radiator. The heater 3 is positioned at the air inlet of the circulating fan 31. This allows the heater 3 to heat the hot air from the waste hot air duct 10 and the circulating hot air from the oven 11, thereby shortening the drying time and improving efficiency. The length of the oven 11 is determined based on the drying and stretching requirements of the fabric 9 and the operating environment. It can also be constructed by connecting multiple chambers. Furthermore, multiple backup hot air chambers 2, circulating fans 31, and waste hot air ducts 10 can be evenly distributed on the oven 11 according to its length to improve the uniformity of hot air intake. The fabric guiding device consists of at least two layers of guide roller groups 13 or mesh belts arranged vertically within the drying oven 11, such as 1 layer, 2 layers, 3 layers, 4 layers, 5 layers, or N layers. Each layer of guide roller group 13 can have a rotating guide roller at each end within the drying oven 11, with a support roller rotating between the two ends for supporting the fabric. The mesh belt can consist of multiple layers of rotating roller pairs arranged vertically within the drying oven 11. The mesh belt is installed on each layer of rotating roller pairs, and a motor and rotating rollers work together to drive the rotating rollers to move the mesh belt. The fabric 9 is supported on each layer of mesh belt, enabling the fabric 9 to move within the drying oven 11. These are common technologies used in fabric drying equipment and will not be described further here. The exhaust gas discharge device includes exhaust gas discharge pipes 14 arranged sequentially along the length of the drying oven 11 at its top. Each exhaust gas discharge pipe 14 is connected to an exhaust gas discharge fan 15. The exhaust pipe 14 has its opening at the top of the oven 11, while the standby hot air chamber 2 is located at the bottom of the oven 11, facilitating the drying of the fabric. The number of exhaust pipes 14 can be determined according to the length of the oven 11, and multiple exhaust pipes 14 can be combined into a main pipe before being discharged by the exhaust fan 15, simplifying the structure. In the case where the oven 11 is composed of multiple connected chambers, the fabric guiding device passes through the oven 11 formed by connecting the various chambers.

[0020] like Figure 2As shown, the setting device 35 includes a setting chamber 16 located below the oven 11. The setting chamber 16 is connected to a hot air supply device and a waste hot air discharge pipe 12. The fabric outlet mechanism 7 is located at the fabric outlet end of the setting chamber 16. The fabric inlet end of the oven 11 and the fabric outlet end of the setting chamber 16 are located at the same end of the self-drying setting machine. The fabric synchronous guide roller group 8 is located between the fabric outlet end of the oven 11 and the fabric inlet end of the setting chamber 16. The fabric synchronous guide roller group 8 may include a set of tension adjusting rollers 17 and expansion rollers 4 to adjust the tension of the fabric 9 entering the setting chamber 16 and prevent the fabric from wrinkling. A stretching setting mechanism 18 is provided inside the setting chamber 16. The stretching setting mechanism 18 adopts the stretching setting mechanism 18 currently used on setting machines. The length of the setting chamber 16 is determined according to the drying and stretching requirements of the fabric 9 and the working environment. Alternatively, multiple setting chambers can be connected separately, with the stretching mechanism 18 passing through the setting chamber 16 formed by connecting the separate setting chambers.

[0021] In this invention, the drying oven 11 can be directly installed on the top of the setting chamber, so that the waste hot air pipe 10 can be integrated with the waste hot air discharge pipe 12, and its air inlet end can be directly connected to the setting chamber. The structure is simple and the installation is convenient.

[0022] like Figure 1 and 2 As shown, the hot air supply device includes a hot air chamber 19 located at the lower part of the setting chamber 16. The hot air chamber 19 is connected to the setting chamber 16. Air distribution chambers connected to the hot air chamber 19 can be arranged on the upper and lower sides of the stretching and setting mechanism 18 within the setting chamber 16. Air holes are distributed in the air distribution chambers on the side facing the fabric 9 to improve the uniformity of the high-temperature hot air blowing onto the fabric 9. A hot air generator 20 is installed inside the hot air chamber 19, and an air inlet 21 is provided on the hot air chamber 19. An air intake fan 22 is installed at the air inlet 21. The hot air generator 20 can be a natural gas direct-fired air-heated hot air generator currently used in setting machines, or an electric heater-heated air generator, or a hot air generator heated by a heat transfer oil and steam radiator. When the shaping chamber 16 is composed of multiple shaping chambers connected together, each shaping chamber can be equipped with a hot air chamber 19, a hot air generator 20, an air distribution chamber, an air inlet 21, and an air intake fan 22. Each shaping chamber is connected to a waste hot air discharge pipe 12 and the waste hot air is discharged in a common pipe to reduce the difference in waste hot air delivered by the waste hot air pipe 10.

[0023] A heat exchange device for heating air can be installed at the outlet of the waste hot air exhaust pipe 12, and the heat exchange device is connected to the waste hot air pipe 10. Since existing fabric shaping equipment mostly uses natural gas direct-fired air generators to obtain high-temperature air, and natural gas combustion can affect some white or light-colored fabrics such as polyester fibers, to avoid this phenomenon, a heat exchange device, such as a radiator connected to the waste hot air exhaust pipe 12, is installed at the outlet of the waste hot air exhaust pipe 12. The high-temperature hot air discharged from the shaping chamber heats the radiator, and the air is heated through heat exchange via the radiator. The heated high-temperature air then enters the drying oven 11 through the waste hot air pipe 10 and a circulating fan for fabric drying. The establishment of the heat exchange device makes this invention applicable to different fabrics, greatly improving its operational range.

[0024] like Figure 1 and 2 As shown, the waste heat air duct 10 is equipped with an air volume regulating device 1, such as a control valve, to adjust the air volume and improve the operating range of this utility model.

[0025] The shaping device 35 in this utility model can be an existing shaping machine. It is only necessary to determine the length of the shaping machine according to the actual production needs, then remove the fabric feeding mechanism 6 at the fabric feeding end of the shaping machine, and then directly install the drying device on the top of the shaping machine. The fabric feeding mechanism 6 is set at the fabric feeding end of the drying device 34. The fabric synchronous guide roller group 8 is added to the fabric output end of the drying device 34 and the fabric feeding end of the shaping machine. The fabric output mechanism 7 of the shaping machine is the original fabric output mechanism and is still set at the fabric output end of the shaping machine.

[0026] like Figure 3 As shown, the fabric feeding mechanism 6 and the fabric discharging mechanism 7 in this utility model are both commonly used mechanisms on current setting machines. For example, the fabric feeding mechanism 6 uses a fabric transport trolley 23 to store and transport the dyed or soaked fabric 9. After the fabric 9 is drawn out from the fabric transport trolley 23, it passes through the fabric feeding traction roller 25, the multi-channel fabric feeding guide roller 26, the expansion roller 4, and the tension adjustment roller group 27 on the fabric feeding frame 32 in sequence before being introduced into the guiding device of the drying device. The fabric discharging mechanism 7 is the fabric discharging mechanism that introduces the set fabric 9 into the fabric discharging frame 33, which uses the fabric discharging traction roller 28, the multi-channel fabric discharging guide roller 29, and the fabric folding mechanism 30. The fabric folding mechanism 30 folds the fabric back and forth on the fabric discharging trolley 24.

[0027] In practical use, regardless of whether the oven 11 is located above, below, to the left, right, front, or rear of the setting chamber, or whether it is near or far, the waste hot air discharged from the setting chamber via the waste hot air exhaust pipe 12 or the fresh hot air obtained through heat exchange via the heat exchange device enters the oven 11 through the waste hot air pipe 10 to dry and reuse the fabric. The waste hot air can be blown into the oven by a waste hot air exhaust fan installed on the setting chamber or drawn into the oven by a circulating fan 31 installed on the oven. When the oven 11 and the setting chamber are arranged vertically, the oven 11 can be mounted on a support platform 5, with the setting chamber positioned below the support platform 5; or the setting chamber can be mounted on a support platform 5, with the oven 11 positioned below the support platform 5.

[0028] like Figure 1 As shown, the oven 11 can use a 5-layer guide roller group 13. During operation, the fabric transport trolley 23 carrying the dyed or impregnated fabric 9 is moved to the fabric inlet mechanism 6, and the fabric outlet trolley 24 is moved to the fabric outlet mechanism 7. The hot air generator 20 is started to heat the air. The air intake fan 22, the circulating fan 31, and the exhaust fan 15 work. The high-temperature hot air flows in the setting chamber 16 and the oven 11. After the temperature in the setting chamber 16 reaches the predetermined working temperature, the fabric 9 is pulled out from the fabric transport trolley 23 under the traction of the fabric guide and introduced into the oven 11 through the fabric inlet mechanism 6, bypassing each layer of guide roller group 13 for pre-drying. After pre-drying, the fabric 9 moves forward out of the oven 11 and is then introduced into the setting chamber 16 through the fabric synchronous guide roller group 8 into the stretching and setting mechanism 18 for drying and stretching and setting. Finally, the dried and stretching and setting fabric 9 moves forward out of the setting chamber 16 and is folded and collected in the fabric outlet trolley 24 by the fabric outlet mechanism 7. During operation, the high-temperature air heated by the hot air generator 20 is formed into high-temperature hot air by the air intake fan 22 and enters the setting chamber 16. With the cooperation of the stretching and setting mechanism 18, the pre-dried fabric 9 is subjected to high-temperature drying and stretching and setting. After high-temperature drying and stretching and setting, the temperature of the high-temperature hot air decreases and the moisture content increases, forming waste hot air. The waste hot air is blown into the drying room through the waste hot air pipe 10 and the circulating fan 31 to pre-dry the high-humidity and low-temperature fabric 9. After pre-drying, the waste gas is discharged by the waste gas exhaust fan 15.

[0029] This utility model has the following characteristics in use: 1. This waste heat exhaust self-circulation drying and shaping machine first uses high-temperature hot air to dry and stretch the pre-dried fabric 9, which has a high temperature and low moisture content, and then uses hot air that has been dried and stretched to reduce the temperature but still contains a lot of heat to pre-dry the wet fabric 9, which has a low temperature and high moisture content. This greatly improves the drying efficiency and heat utilization rate, and the heat utilization rate can be increased by 35-40%, reducing energy consumption. 2. The drying oven 11 of this waste heat exhaust self-circulation drying and shaping machine uses a multi-layer guide roller group 13 to guide the cotton fabric and stretch the cotton fabric. Its stretching effect is much higher than that of the current shaping machine. The mesh belt layer can also be used to pre-shrink the chemical fiber fabric or the fabric that needs to be pre-shrinked in advance, i.e., loose feeding. 3. Because the drying device 34 is used to pre-dry the fabric 9 before stretching and shaping, the drying workload of the shaping chamber 16 of the shaping device 35 is greatly reduced, and the length of the shaping chamber 16 is greatly reduced. The drying device and the shaping device are arranged vertically after the length of the shaping chamber 16 is reduced, which greatly reduces the floor space of this self-drying and shaping machine that uses waste heat exhaust and self-circulation. 4. The fabric inlet and outlet of this waste heat exhaust self-circulation drying and shaping machine can be located at the same end of the entire shaping machine, which greatly improves the convenience of fabric inlet and outlet operations, reduces manpower consumption, and improves production efficiency; of course, the fabric inlet and outlet can also be located on the front and rear sides of the self-drying and shaping machine according to actual installation needs and production requirements.
