It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0027] See also Figures 1 to 8 A shaping machine oven comprises a plurality of oven bodies 1 connected in sequence, a hot air duct 2 arranged in the oven body 1, a nozzle assembly 3 communicating with the hot air duct 2, a drying chamber 4 formed by the outer wall of the hot air duct 2 and the inner wall of the oven body 1, a filter screen 5 arranged on the hot air duct and used to connect the hot air duct 2 and the drying chamber 4, and a vent 6 arranged on the side wall of the oven body 1 and used to communicate with another adjacent oven body 1, the nozzle assembly 3 comprises a nozzle body 31, and a plurality of round tube nozzles 32 arranged on the nozzle body 31 and communicating the inside and outside of the nozzle body 31.

[0028] The present invention discloses a shaping machine oven, which uses a round tube nozzle, so that it is not easy to generate large waves under different wind speeds, so that the tension deviation of the cloth surface is small, the cloth surface is smoother, and the color difference and flatness problems of the cloth surface are improved. In addition, the round tube nozzle is smoother than the traditional nozzle and is not easy to get caught on the cloth surface, thereby improving production efficiency and product quality.

[0029] Furthermore, as a preferred implementation of the present solution but not a limitation, the nozzle assembly 3 further includes a cover plate 33 located above the circular tube nozzle 32 , and a plurality of circular holes 34 corresponding to each of the circular tube nozzles 32 are formed on the cover plate 33 .

[0030] In this embodiment, the cover plate 33 can play the role of returning air, so that the hot air circulates more evenly in the oven, improving the drying and shaping effects. Secondly, the cover plate 33 can prevent the cloth from snagging during the drying process, thereby improving product quality. In addition, by providing a circular hole 34 corresponding to the circular tube nozzle 32 on the cover plate 33, the distribution of the hot air can be further optimized, so that the cloth is heated more evenly, and the problems of color difference and unevenness can be reduced. There are other possible improvements. For example, a guide plate or a spoiler can be added to the cover plate 33 to further optimize the flow path of the hot air and improve the drying effect. In addition, the shape, size and position of the cover plate 33 can be adjusted according to the characteristics and drying requirements of different fabrics to achieve a better drying effect.

[0031] Furthermore, as a preferred implementation mode of the present solution but not limiting, it includes two nozzle assemblies 3 which are arranged vertically opposite to each other up and down.

[0032] In this embodiment, the fabric can be fully dried and shaped by the cooperation of the upper and lower nozzle assemblies. This design can increase the coverage area of ​​the hot air, so that the upper and lower surfaces of the fabric can be evenly affected by the hot air, thereby improving the drying effect and shaping quality. The vertical layout of the upper and lower nozzles helps to form a stable airflow field, reduce the swing and uneven tension of the fabric during the drying process, which helps to avoid wrinkles and color differences in the fabric and improve the flatness and color consistency of the finished product. In addition, this design can also adjust the air volume and wind speed of the upper and lower nozzles according to the thickness of the fabric and the drying requirements, so as to achieve more precise process control.

[0033] Furthermore, as a preferred implementation manner of the present solution but not a limitation, the oven body 1 is further provided with an exhaust passage 7 for connecting the baking chamber 4 with the outside of the oven body 1 .

[0034] In this embodiment, by providing the exhaust channel 7, the hot and humid air in the oven can be discharged in time, the temperature and humidity in the oven can be kept stable, and the drying effect and shaping quality can be improved. Secondly, the provision of the exhaust channel 7 can increase the air circulation speed in the oven, promote the circulation and distribution of hot air, make the fabric heated more evenly, reduce the problems of color difference and unevenness, increase the discharge amount of oil fume gas, reduce the residence time of the circulating air containing oil fume gas in the oven, and reduce the condensation of oil droplets and smoke.

[0035] Further, as a preferred implementation manner of the present solution but not a limitation, the exhaust passage 7 includes a first exhaust passage 71 and a second exhaust passage 72 respectively located on both sides of the nozzle assembly 3 .

[0036] In this embodiment, by respectively arranging the first exhaust duct 71 and the second exhaust duct 72 on both sides of the nozzle assembly 3, the air in the oven can be uniformly extracted, and the temperature unevenness and color difference problems caused by unilateral exhaust can be avoided, and the uneven distribution of temperature and wind force caused by unilateral exhaust can be effectively avoided, thereby reducing the color difference and unevenness of the fabric during the drying process. At the same time, the setting of the exhaust ducts on both sides helps to quickly discharge moisture and oil smoke in the oven, reduce the risk of oil droplet condensation and smoke, and improve the safety and cleanliness of the production environment. The design of double-sided exhaust can make the air circulation in the oven smoother, improve the drying effect and shaping quality. The setting of the first exhaust duct 71 and the second exhaust duct 72 can increase the air circulation speed in the oven, promote the circulation and distribution of hot air, and make the fabric heated more evenly. Thereby improving product quality.

[0037] Further, as a preferred embodiment of the present invention but not limiting, an amplitude modulation mechanism 8 is provided on the side wall of the oven body 1, and the amplitude modulation mechanism 8 includes an amplitude modulation frame 81, an amplitude modulation screw 82 provided on the amplitude modulation frame 81, and the amplitude modulation screw 82 and the inner side wall of the amplitude modulation frame 81 are surrounded to form an opening 83 connecting the hot air duct 2 and the outside of the oven body 1. The setting of the opening can increase the flow space of the circulating air inside the oven.

[0038] Furthermore, as a preferred implementation of the present solution but not a limitation, the amplitude modulation screw 82 is located below the nozzle assembly 3 .

[0039] In this embodiment, it helps to reduce the air flow resistance between the hot air duct 2 and the outside of the oven body 1, reduce the circulating air flow resistance, increase the circulating air flow space, and improve the oil dripping and smoke problems.

[0040] Furthermore, as a preferred embodiment of the present invention but not limiting, it further includes a middle plate 9 disposed in the oven body 1 and located above the filter screen 5. In this embodiment, the middle plate is shortened and reduced compared to the prior art, thereby increasing the flow space of the circulating air inside the oven.

[0041] Furthermore, as a preferred implementation mode of the present solution but not a limitation, a heat-resistant medium is attached to the outer side of the amplitude modulation frame 81. In the present embodiment, the heat-resistant medium is high-temperature adhesive tape, ceramic fiber paper, asbestos material, etc., which provides additional thermal protection and performance advantages for the oven body 1. The attachment of the heat-resistant medium can effectively isolate the heat generated by the amplitude modulation frame 81 in a high-temperature operating environment, reduce the heat loss to the outside of the oven, and thus improve the overall thermal efficiency and energy-saving effect. In addition, this heat-resistant medium also helps to protect the amplitude modulation frame 81 and its connecting parts from the influence of long-term high temperature, prolong the service life of the equipment, and reduce maintenance costs.

[0042] Furthermore, as a preferred embodiment of the present invention but not limiting, a temperature detector is also provided at the vent 6 of the oven body 1. The exhaust air volume can be automatically controlled according to the set temperature; when there is no cloth, the circulation fan and the exhaust fan run at a low speed.

[0043] Further, as a preferred implementation manner of the present solution but not a limitation, the hot air duct 2, the nozzle 3, the drying chamber 4, the exhaust channel 7 or the vent 6 are sequentially connected to form an exhaust duct.

[0044] In this embodiment, the hot air duct 2, the nozzle 3, the drying chamber 4, the exhaust channel 7 or the vent 6 are sequentially connected to achieve timely exhaust of the hot and humid air in the oven. The design of the exhaust duct can keep the temperature and humidity in the oven stable, and improve the drying effect and shaping quality.

[0045] Further, as a preferred implementation manner of the present solution but not a limitation, the hot air duct 2, the nozzle 3, the drying chamber 4, the exhaust duct 7, and the hot air duct 2 are sequentially connected to form a circulation duct.

[0046] In this embodiment, the hot air duct 2, the nozzle 3, the drying chamber 4, the exhaust duct 7 and the hot air duct 2 are sequentially connected to achieve the circulation of hot air in the oven. The circulating hot air can improve the drying effect and shaping quality, because the hot air can fully contact the fabric during the circulation process, taking away the moisture and heat on the fabric, making the fabric heated more evenly, thereby reducing the color difference and unevenness.

[0047] Further, as a preferred embodiment of the present invention but not limiting, the filter screen 5 is located near the exhaust passage 7. This can reduce the impact of oven air leakage on circulating air and exhaust air, and improve the problems of oil dripping and smoke.

[0048] Furthermore, as a preferred implementation of this solution but not a limitation, a medium-pressure steam condensate waste heat recovery system is provided. Specifically, the condensate with a temperature of more than 150 degrees discharged from each oven heat exchanger is sent to the waste heat recovery device at the top of the first box, and the condensate temperature is reduced to less than 100 degrees after heat exchange, thereby saving steam and improving oven oil dripping.

[0049] The working principle of this embodiment is as follows:

[0050] The present invention discloses a shaping machine oven, which uses a round tube nozzle, so that it is not easy to generate large waves under different wind speeds, so that the tension deviation of the cloth surface is small, the cloth surface is smoother, and the color difference and flatness problems of the cloth surface are improved. In addition, the round tube nozzle is smoother than the traditional nozzle and is not easy to get caught on the cloth surface, thereby improving production efficiency and product quality.
