Description

Technical Field

[0001] This invention relates to the field of textile printing and dyeing technology, and more specifically, to a setting machine bellows structure and a setting machine. Background Technology

[0002] In existing technologies, textile machinery such as tenter frame machines are commonly used in the finishing processes of textile fabrics. After dyeing and washing, the surface of the fabric often has wrinkles and unevenness, requiring drying and shaping for subsequent setting. Existing setting machines typically have multiple fans that continuously supply high-temperature steam into the air box to set the textile fabric. However, the fans are generally located in the middle of the lower side of the air box, resulting in uneven temperature distribution within the air box. The temperature at the center of the air box is significantly higher than the temperature at the periphery, leading to inconsistent temperatures received by the textile fabric and uneven setting effect. After the high-temperature gas enters the air box, it must pass through a filter to remove impurities before contacting the textile fabric. After prolonged operation, the filter needs to be cleaned; otherwise, the ventilation and heat transfer rates will decrease. Current cleaning methods involve opening the air box and removing the filters one by one, which is time-consuming and labor-intensive. Therefore, a technical solution is needed to address these problems. Summary of the Invention

[0003] The purpose of this invention is to overcome the shortcomings of the prior art, make the internal temperature of the air box more uniform, make the filter easier to clean, and provide a stenter air box structure and stenter.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] This invention discloses a stenter air box structure and a stenter, including a housing, an inner air box, and a filter device. The housing includes a fan box and an air outlet. The inner air box is installed inside the housing and located at the bottom of the housing. The air outlet is located at the top of the housing. A first fan is installed in the fan box and connected to the inner air box. The upper end of the inner air box has an opening. The inner air box has multiple first air guide plates. The first air guide plates extend along the air outlet direction of the first fan and are wavy. The air guide plates are arranged along the length of the inner air box, and an air guide channel is formed between two adjacent first air guide plates. The width of the air guide channel gradually increases from the middle of the inner air box to both sides. The filter device is located above the inner air box. The filter device includes a filter screen and two cleaning mechanisms. The two cleaning mechanisms are located at both ends of the length of the box. The cleaning mechanism includes a rotating shaft. The two ends of the filter screen are fixed on the two rotating shafts. The synchronous rotation of the two rotating shafts can realize the synchronous winding and unwinding of the two ends of the filter screen.

[0006] Furthermore, the inner air box includes a closed area and a guide area. The closed area is provided with an air inlet, which is connected to the first fan. The closed area connects the first fan and the guide area. The closed area is funnel-shaped, and the cross-sectional area of ​​the closed area gradually increases from the air inlet toward the guide area. The first guide plate is arranged and installed in the guide area.

[0007] Furthermore, the inner air box is provided with a second air guide plate, and there are two second air guide plates, which are respectively located on the outside of the two first air guide plates at the two outermost ends.

[0008] Furthermore, an annular air trough is formed between the inner air box and the interior of the box body. A cover plate is installed on the top of the annular air trough, and the cover plate is provided with a ventilable mesh plate. At least one second fan is installed in the box body, and the second fan can discharge air into the annular air trough, forming an annular airflow in the annular air trough.

[0009] Furthermore, the inner air box is provided with a plurality of air inlet holes, the air inlet holes are located on the side of the inner air box away from the first fan, each air inlet hole is located in a corresponding air guide channel, the air inlet hole is located at the end of the air guide channel away from the first fan, and the air inlet hole connects the air guide channel and the annular air groove.

[0010] Furthermore, the inner air box is provided with multiple air guide plates, and each air guide hole is provided with an air guide plate. The air guide plate is located on the outer wall of the inner air box and on the side of the air guide hole closer to the second fan. The air guide plate is inclined, and the end of the air guide plate away from the inner air box is inclined in the direction away from the second fan.

[0011] Furthermore, there are two second fans, which are located at two opposite corners of the inner air box.

[0012] Furthermore, the cleaning mechanism includes a brush plate, a support frame, and a drawer. The brush plate includes bristles that abut against the outer wall of the filter screen roll located on the rotating shaft. The support frame is fixedly installed on the housing. The brush plate extends along the length of the rotating shaft and is slidably installed on the support frame. The drawer has an opening at its upper end and is slidably installed on the support frame. The drawer is located below the brush plate and extends along the length of the rotating shaft. The drawer can be pulled out of the housing.

[0013] Furthermore, the cleaning mechanism includes a pressure roller and a guide rod. The support frame includes a guide plate, the guide rod passes through the guide plate, the guide rod is provided with a first baffle and a second baffle, the guide rod is equipped with a spring, the spring is located between the first baffle and the guide plate, the pressure roller is installed at the end of the guide rod facing the rotating shaft, the spring supports the first baffle and thus the pressure roller abuts against the outer wall of the wire mesh roll, and the second baffle is located at the end of the guide rod away from the pressure roller.

[0014] A setting machine includes the above-mentioned setting machine air box structure. The setting machine air box structure has multiple air boxes. Both ends of the length direction of the box body are provided with channel openings. The channel openings of two adjacent boxes are connected to each other. The channel openings allow fabric to pass through and the fabric passes over the filter screen.

[0015] The beneficial effects of this invention are:

[0016] 1. The first air guide plate in the inner air box at the bottom of the box body in this invention can divide the hot air sent in by the first fan. The hot air flows through the air guide channel between the wave-shaped air guide plates, which can slow down the flow rate of the hot air. This increases the wind resistance in the middle of the inner air box and reduces the wind resistance on both sides of the inner air box. This slows down the wind speed in the middle of the inner air box and increases the wind speed on both sides, increasing the temperature on both sides of the inner air box and balancing the temperature between the middle and both sides of the inner air box, making the temperature of the hot air flowing upward from the inner air box more uniform.

[0017] 2. In this invention, an annular air groove is formed between the inner air box and the box body. A second fan is installed in the annular air groove to form an annular airflow. The inner air box is located at the air intake hole at the end of the air guide channel away from the first fan. The air intake hole can guide some of the hot air in the air guide channel into the annular air groove, increasing the temperature at the end of the air guide channel away from the first fan, making the temperature of the inner air box more uniform. The annular airflow formed by the annular air groove can play a role in surrounding and insulating the inner air box, making the temperature in the inner air box more stable.

[0018] 3. In this invention, the filter screen is wound and unwound by two synchronously rotating shafts. After the filter screen has been used for a period of time, the rotating shafts will change the part of the filter screen located above the inner air box. The filter screen with dust is wound up. During the winding process, the dust on the wound part of the filter screen is brushed off by the brush plate of the cleaning mechanism. The dust can be concentrated in the drawer. After cleaning, the drawer can be pulled out to clean the dust. The filter screen is more convenient to clean, and there is no need to take out the filter screen for time and effort to clean it.

[0025] The technical solutions in this embodiment will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0026] Example 1:

[0027] like Figure 1 , Figure 2 , Figure 3 , Figure 4As shown, this embodiment discloses a styling machine air box structure including a housing 1, an inner air box 2, and a filter device 3. The housing 1 includes a fan box 11 and an air outlet 12. The inner air box 2 is installed inside the housing 1 and is located at the bottom of the housing 1. The air outlet 12 is located at the top of the housing 1. A first fan 21 is installed in the fan box 11. The inner air box 2 includes an air guide box 22. The first fan 21 is connected to the air guide box 22. The air guide box 22 includes a closed area 222 and an air guiding area 223. The upper and lower surfaces of 22 are both closed. The closed area 222 is provided with an air inlet 221, which is connected to the first fan 21. The closed area 222 connects the first fan 21 and the air guide area 223. The closed area 222 is funnel-shaped. The cross-sectional area of ​​the closed area 222 gradually expands from the air inlet 221 toward the air guide area 223. The hot air from the first fan 21 enters from the air inlet 221 and can only flow through the closed area 222 to the air guide area 223, so that the hot air entering can diffuse.

[0028] The air guide box 22 has an opening at its upper end, that is, an opening on the upper surface of the air guide area 223. The air guide box 22 has multiple first air guide plates 224, which are arranged and installed within the air guide area 223. The first air guide plates 224 extend along the air outlet direction of the first fan 21. Hot air from the enclosed area 222 enters the air guide area 223 and contacts the first air guide plates 224. The first air guide plates 224 are wavy. Multiple first air guide plates 224 are arranged along the length of the inner air box 2, and an air guide channel 225 is formed between two adjacent first air guide plates 224. The width of the air guide channel 225 extends from the middle of the inner air box 2 towards... The sides gradually increase in size. The first air guide plate 224 in the inner air box 2 can divide the hot air sent in by the first fan 21. The hot air flows through the air guide channel 225 between the wave-shaped first air guide plates 224, which can slow down the flow rate of the hot air. The smaller the distance between the two first air guide plates 224, the slower the flow rate of the hot air. This increases the wind resistance in the middle of the inner air box 2 and reduces the wind resistance on both sides of the inner air box 2. This slows down the wind speed in the middle of the inner air box 2 and increases the wind speed on both sides, increasing the temperature on both sides of the inner air box 2 and balancing the temperature between the middle and both sides of the inner air box 2, making the temperature of the hot air flowing upward from the inner air box 2 more uniform.

[0029] More preferably, the inner air box 2 is provided with a second air guide plate 226. There are two second air guide plates 226, which are located on the outer side of the two first air guide plates 224 at the two ends. The second air guide plate 226 is a flat plate. The second air guide plate 226 can make the flow rate of hot air on both sides of the inner air box 2 faster than the flow rate of hot air in the air guide channel 225, reduce the temperature difference between the two sides and the middle of the inner air box 2, and make the temperature in the inner air box 2 more stable.

[0030] An annular air trough 14 is formed between the inner air box 2 and the interior of the box body 1. A cover plate 141 is installed on the top of the annular air trough 14. The cover plate 141 is provided with a mesh plate that allows ventilation. Two second fans 15 are installed in the box body 1. The two second fans 15 are located at two opposite corners of the inner air box 2. The second fans 15 can exhaust air into the annular air trough 14, forming an annular airflow. The annular airflow formed by the annular air trough 14 can play a role in surrounding and insulating the inner air box 2, making the temperature in the inner air box 2 more stable.

[0031] The inner air box 2 is provided with multiple air inlets 227. The air inlets 227 are located on the side of the inner air box 2 away from the first fan 21. Each air inlet 227 is located in a guide channel 225. The air inlet 227 is located at the end of the guide channel 225 away from the first fan 21. The air inlet 227 connects the guide channel 225 and the annular air groove 14. The air inlet 227 can guide some of the hot air in the guide channel 225 into the annular air groove 14, increase the temperature at the end of the guide channel 225 away from the first fan 21, and make the temperature of the inner air box 2 more uniform.

[0032] More preferably, the inner air box 2 is provided with a plurality of air guide plates 228, and each air guide hole 227 is provided with an air guide plate 228. The air guide plate 228 is located on the outer wall of the inner air box 2 and on the side of the air guide hole 227 close to the second fan 15. The air guide plate 228 is inclined, and the end of the air guide plate 228 away from the inner air box 2 is inclined in the direction away from the second fan 15. The air guide plate 228 can block the airflow of the second fan 15 toward the air guide hole 227, and prevent the airflow in the annular air groove 14 from affecting the airflow in the air guide channel 225. The airflow flowing in the annular air groove 14 can drive the airflow in the air guide hole 227 so that the airflow in the air guide channel 225 is better guided to the end away from the first fan 21.

[0033] The filter device 3 is located above the inner air box 2. The filter device 3 includes a filter screen 31 and two cleaning mechanisms 32. The two cleaning mechanisms 32 are located at both ends of the length of the box 1. The cleaning mechanism 32 includes a rotating shaft 321. The rotating shaft 321 is controlled by a motor. The two ends of the filter screen 31 are fixed on the two rotating shafts 321. The two rotating shafts 321 rotate synchronously to realize the synchronous winding and unwinding of the two ends of the filter screen 31. The filter screen 31 is located above the inner air box 2. The hot air flow in the inner air box 2 flows through the filter screen 31 to the fabric 4 above for shaping. Dust, lint, etc. in the hot air flow will be blocked and adhered to the filter screen 31. After a certain period of time, the two motors control the two rotating shafts 321 to replace the part of the filter screen 31 located above the inner air box 2. The unclean filter screen 31 can be wound up by one of the rotating shafts 321.

[0034] The cleaning mechanism 32 includes a brush plate 322, a pressure roller 323, a guide rod 324, a support frame 33, and a drawer 34. The brush plate 322 includes bristles 3221, which abut against the outer wall of the mesh roll 311 formed by the filter screen 31 located on the rotating shaft 321. The support frame 33 is fixedly installed on the housing 1. The brush plate 322 extends along the length of the rotating shaft 321. The support frame 33 includes a guide plate 331, through which the guide rod 324 passes. The guide rod 324 is capable of moving horizontally. The guide rod 324 is provided with a first baffle 3241 and a second baffle 3242. A spring 325 is installed on the guide rod 324, located between the first baffle 3241 and the guide plate 331. The pressure roller 323 is installed at the end of the guide rod 324 facing the rotating shaft 321, and the spring 325 supports the first baffle 324. 1. The pressure roller 323 then presses against the outer wall of the mesh roll 311. The second baffle 3242 is located at the end of the guide rod 324 away from the pressure roller 323. The brush plate 322 is slidably installed on the support frame 33. When the mesh roll 311 gradually increases in size due to winding, the pressure roller 323, supported by the mesh roll 311, can gradually compress the spring 325. The position of the brush plate 322 can move with the movement of the pressure roller 323, which can maintain the distance between the brush plate 322 and the mesh roll 311 and prevent the brush bristles 3221 from contacting the mesh roll 311 too much, resulting in poor dust removal effect. Two cleaning mechanisms 32 are set to clean back and forth between the two mesh rolls 311. When one end of the mesh roll 311 is fully wound, the two rotating shafts 321 rotate in opposite directions to unwind the cleaned mesh roll 311 in the opposite direction. The cleaned filter screen 31 can be reused.

[0035] The drawer 34 has an opening at the top and is slidably mounted on the support frame 33. The drawer 34 is located below the brush plate 322 and extends along the length of the pivot 321. The drawer 34 can be pulled out of the box 1 and can collect the dust brushed off by the brush plate 322. The dust can be concentrated in the drawer 34. After cleaning, the drawer 34 can be pulled out to clean the dust, making it more convenient to clean the filter screen 31 without having to take out the filter screen 31 for time-consuming and laborious cleaning.

[0036] Example 2:

[0037] like Figure 5 As shown, this embodiment discloses a stenter including a stenter air box structure as described in Embodiment 1. The stenter air box structure has multiple air boxes. Both ends of the box body 1 in the length direction are provided with channel openings 13. The channel openings 13 of two adjacent boxes 1 are connected to each other. The channel openings 13 allow the fabric 4 to pass through. The fabric 4 passes above the filter screen 31. The channel openings 13 can divide the space above the filter screen 31 in two adjacent boxes 1. The fabric 4 is conveyed by the stenter conveying device. The exhaust gas in the box body 1 can be discharged through the air outlet 12 at the top.
