Description

Technical Field

[0001] This invention relates to the field of oven technology, and in particular to an intelligent airflow regulating device and an oven. Background Technology

[0002] In the production of neoprene rubber, the washed rubber film is squeezed out of most of its water using an extrusion dewatering machine. The extruder consists of two rollers: the lower roller is driven by a rotating device, while the upper roller is pressed against the lower roller by an air compressor, and the roller gap can be adjusted. To prevent the rubber film from sticking to the rollers, both rollers are covered with rubber sheets, on top of which is a fabric layer. After extrusion, the rubber film, containing 30% moisture, enters an oven. The movement of the film within the oven is achieved by a transmission device made of aluminum or stainless steel tubing. Dry, hot air is introduced into the oven to maintain the temperature at approximately 130°C. The film remains in the oven for 4-6 minutes, and the moisture content of the dried film is below 1%.

[0003] However, during the production process, there are often situations where it is necessary to adjust the exhaust volume. Currently, the exhaust volume adjustment of this equipment is located on the air supply duct, which can only adjust the overall air supply volume and cannot adjust the air volume at the air outlet. Summary of the Invention

[0004] The purpose of this invention is to provide an intelligent air volume adjustment device and an oven, which solves the problem mentioned in the background art that the existing exhaust air volume adjustment is located on the air supply duct, which can only adjust the overall air supply volume and cannot adjust the air volume at the air outlet.

[0005] The technical solution adopted in this invention is as follows: An intelligent airflow regulating device includes a first box and a second box mounted on a film conveying mechanism. The first box is used to receive hot air, with its opening facing the film, and an air inlet pipe on its top surface. The second box is used to exhaust air, with its opening facing the film, and an exhaust pipe on its bottom surface. An air distribution box is mounted on the top surface of the first box, with its opening covering the air inlet pipe, and evenly distributed air distribution holes on its bottom surface. A first support plate is mounted in the middle of the air distribution box, and a partition is mounted on the first support plate.

[0045] Furthermore, the terms “first,” “second,” and “third” are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated.

[0046] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation", "connection", and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0047] like Figures 1-3As shown, an intelligent airflow regulating device includes a first housing 2 and a second housing 3 mounted on a film conveying mechanism 1. The first housing 2 is used for hot air intake and is located above the film. The first housing 2 has a trough-shaped structure, with its opening facing the film. An air inlet pipe 4 is installed on the top surface of the first housing 2. The second housing 3 is used for exhaust air and is located below the film. The second housing 3 also has a trough-shaped structure, with its opening facing the film. An exhaust pipe 5 is installed on the bottom surface of the second housing 3. A distribution box 6 is bolted to the top surface of the first housing 2. The distribution box 6 has a trough-shaped structure, with its opening covering the air inlet pipe 4. The bottom surface of the distribution box 6 has evenly arranged distribution holes 7, with a diameter greater than 5mm to prevent the formation of a gas cutting effect. The distribution holes 7 ensure that the hot air is evenly distributed within the first housing 2, avoiding the hot air from taking the shortest route and preventing heat loss. The air is concentrated on one part of the adhesive film; a first support plate 8 is welded to the middle of the air distribution box 6, specifically two first support plates 8 are arranged symmetrically, and a partition plate 9 is fixed to the first support plate 8 by bolts. The partition plate 9 divides the air distribution box 6 into upper and lower air chambers. The partition plate 9 has through holes 10 arranged at equal intervals. The surface of the through holes 10 is located directly below the air inlet pipe 4. An air regulating mechanism 11 is installed on the through holes 10. The air regulating mechanism 11 is used to control the air volume at the air outlet. Then, the hot air after adjusting the air volume is discharged from the air distribution hole 7 to dry the adhesive film. The structure of the air distribution hole 7 on the air distribution box 6 of this application can make the pressure and temperature distribution of the hot air blowing on the adhesive film uniform. By changing the opening and closing degree of the air regulating mechanism 11, the pressure and flow rate of the hot air blowing on the adhesive film can be adjusted, resulting in good drying effect and ensuring the required dryness and quality of the product.

[0048] like Figures 4-6As shown in the embodiment, as an optimization, the air regulating mechanism 11 includes an outer tube 12 disposed on the partition 9. The outer tube 12 is T-shaped, with its upper end corresponding to the through hole 10. An air nozzle 13 is fixed to the lower end of the outer tube 12 by screws. The air nozzle 13 has a funnel-shaped air guide vent 14 at its center. A support 15 is fixed inside the outer tube 12 by screws. There are two supports 15, symmetrically arranged. An inner tube 16 is fixedly connected to the air inlet 14 through a gap. A groove 17 is provided on the lower end face of the inner tube 16. A sliding core 18 adapted to the air inlet 14 is slidably connected in the groove 17. The sliding core 18 is conical in shape. A guide sleeve 19 is fixed in the middle of the inner tube 16. A guide post 20 is slidably connected to the guide sleeve 19. The lower end of the guide post 20 is connected to the sliding core 18. An air injection chamber 21 is provided at the upper end of the inner tube 16. The air injection chamber 21 is located on the upper side of the guide sleeve 19. A first air injection chamber is provided on the air injection chamber 21. Air inlet 22 and second air inlet 23 are provided. A pusher pipe 24 is installed on the first air inlet 22, and a compressor pipe 25 is installed on the second air inlet 23. A sealing shroud 26 is connected to the side wall of the guide post 20. The sealing shroud 26 is slidably fitted with the air injection chamber 21. The air injection chamber 21 has a stepped groove 27 that limits the downward movement of the sealing shroud 26. The stepped groove 27 is located above the first air inlet 22. A guide seat 28 is fixed to the upper end of the inner tube 16 by screws. The guide seat 28 slides against the guide post 20. The guide seat 28 is connected to a tail cap 29. The adjustment process is as follows: by injecting air into the first air inlet 22, the sealing cover 26 moves upward, and the guide post 20 makes the sliding core 18 move away from the air nozzle 13, thereby increasing the gap between the sliding core 18 and the air guide 14 and changing the air flow. By injecting air into the second air inlet 23, the sealing cover 26 moves downward, and the guide post 20 makes the sliding core 18 move toward the air nozzle 13, thereby decreasing the gap between the sliding core 18 and the air guide 14 and changing the air flow.

[0049] like Figure 7 and Figure 8As shown, as an optimization of the embodiment, the film conveying mechanism 1 includes a base, with several bases arranged in a row. Two frames 30 are mounted on the bases, arranged symmetrically, forming a film conveying channel between them. A first bearing seat 31 is mounted on each frame 30, and a first rotating shaft 32 is rotatably connected to the opposite first bearing seat 31. Two symmetrically arranged first sprockets 33 are mounted on the first rotating shaft 32, located within the film conveying channel. One of the first rotating shafts 32 is connected to a first motor 34 via a chain drive. The frame 30 also has an adjustable tension first bearing seat 31, with a first motor 34 rotatably connected to the opposite first bearing seat 34. The second rotating shaft 35 has two symmetrically arranged second sprockets 36 mounted on it, which are located within the film conveying channel. The second sprockets 36 are identical to the first sprockets 33. A closed-loop support chain 37 meshes between the two second sprockets 36 and the two first sprockets 33, and the support chain 37 is used to convey the film. Glue rollers 38 are connected to the side walls of the first rotating shaft 32 and the second rotating shaft 35, and the two glue rollers 38 are tactilely connected to the support shaft of the support chain 37. The first housing 2 is located on the frame 30, above the film, and the second housing 3 is located on the frame 30, below the film. This application, by setting up the film conveying mechanism 1, can convey the film. The chamber drying process of the adhesive film involves the drying medium (hot air) transferring heat to the wet adhesive film. Moisture on the surface of the wet film vaporizes and diffuses into the hot air through the surface vapor film. Simultaneously, the vaporization of moisture on the material surface creates a humidity difference between the inside and surface of the film. Therefore, moisture inside the material diffuses to the surface in either gaseous or liquid form, ultimately entering the hot air as a gas. Clearly, the hot air acts as both a heat carrier and a moisture carrier. It should be noted that a necessary condition for drying is that the pressure of the water vapor on the adhesive film surface must be greater than the partial pressure of water vapor in the hot air. The greater the pressure difference, the faster the drying process. Therefore, the hot air must promptly remove the vaporized water vapor to maintain a certain mass transfer driving force. Thus, drying is a process combining heat and mass transfer, and the drying rate is governed by both the heat transfer rate and the mass transfer rate.

[0050] like Figure 9 As shown, as an optimization of the embodiment, the bottom surface of the air distribution box 6 is fixed with a baffle plate 39 by bolts. The baffle plate 39 is U-shaped and corresponds one-to-one with the air distribution holes 7. The horizontal section of the baffle plate 39 changes the direction of the air discharged from the air distribution holes 7, disperses the small airflow again, and changes the downward airflow direction to a horizontal flow, so that the hot air can be quickly dispersed in the first box 2.

[0051] like Figure 10 and Figure 11As shown, as an optimization of the embodiment, a second support plate 40 is welded inside the first housing 2. The second support plate 40 is in the shape of a frame. A perforated plate 41, a filter cloth 42, and a third support plate 43 arranged from top to bottom are fixed to the bottom surface of the second support plate 40 by bolts. The third support plate 43 is the same as the second support plate 40. By setting the perforated plate 41 and the filter cloth 42, multiple streams of hot air are evenly transmitted to the membrane through the filter cloth 42. The sum of the cross-sectional areas of the small streams of air is equal to the cross-sectional area of ​​a single stream of air. The small streams of air are less likely to form wind tunnels when passing through the breathable layer. In addition, the filter cloth 42 can separate impurities in the hot air, preventing impurities from adhering to the membrane and affecting the quality of the membrane. This drying method can prevent the membrane from shifting position on the support chain 37.

[0052] like Figures 12-14 As shown, as an optimization of the embodiment, considering that the hot air discharged by the air regulating mechanism 11 will blow directly onto the inner bottom surface of the air distribution box 6 without a guiding structure, a first shaft 44 is installed inside the air distribution box 6. Equally spaced guide members 45 are connected to the first shaft 44, and each guide member 45 corresponds to one of the air regulating mechanisms 11. Each guide member 45 includes a vertical plate 46, with the first shaft 44 located in the middle of the vertical plate 46. The top and bottom surfaces of the vertical plate 46 have arc-shaped grooves 47. A guide head 48 is fitted into the upper arc-shaped groove 47 with a clearance fit. The guide head 48 consists of an arc-shaped portion 49 and a first shaft tube portion 50. The arc-shaped portion 49 is opposite to the air regulating mechanism 11, and the first shaft tube portion 50 is fitted into the vertical plate 46 with a clearance fit. The rotation angle of the arc-shaped portion 49 is... The arc-shaped groove 47 defines the first shaft tube 50, which is rotatably connected to the second shaft rod 51. The arc-shaped groove 47 located on the lower side is fitted with a guide tail 52, which is composed of a V-shaped part 53 and a second shaft tube 54. The V-shaped part 53 is opposite to the bottom surface of the air distribution box 6. The second shaft tube 54 is fitted with the vertical plate 46. A third shaft rod 55 is rotatably connected to the second shaft tube 54. The two inclined surfaces of the V-shaped part 53 are fixed with springs 56. The free section of the springs 56 is connected to the bow-shaped part 49. The bow-shaped part 49, the two springs 56, and the V-shaped part 53 form a teardrop-shaped structure. By setting the guide member 45, the hot air discharged by the air regulating mechanism 11 can be divided into two streams. The hot air can quickly fill the air distribution box 6, and the air distribution effect is further improved.

[0053] like Figures 15-17 As shown, and Figure 31As shown, as an optimization of the embodiment, the first shaft 44 extends outside the first housing 2 and is rotatably connected to the first housing 2. A baffle rod 57 is installed on the side wall of the first shaft 44 outside the first housing 2. The baffle rod 57 has two flanges 58, and the surface of the flanges 58 is perpendicular to the surface of the vertical plate 46. A fourth support plate 59 is installed on the first housing 2, and a drive unit is installed on the fourth support plate 59. The drive unit drives the baffle rod 57 to reciprocate. The drive unit includes a second bearing seat 60 provided on the fourth support plate 59. There are two second bearing seats 60, which are symmetrically arranged. A short shaft 61 is rotatably connected to the second bearing seat 60, and a cam 6 is installed on the short shaft 61. 2. The tips of the two cams 62 face each other. The cams 62 are used to drive the baffle rod 57 to rotate, which in turn drives the first shaft 44 and the guide member 45 to reciprocate. A first gear 63 is installed on the short shaft 61. A second gear 64 meshes between the two first gears 63. The second gear 64 is driven by a second motor 65, which is connected to the fourth support plate 59. In the flow guiding process, the second motor 65 drives the two first gears 63 to rotate in the same direction. As a result, the two cams 62 reciprocate to lift the baffle rod 57, realizing the reciprocating swing of the first shaft 44 and the guide member 45. The swing process makes the hot air fill the air distribution box 6, which has a good air distribution effect. In addition, the spring 56 uses its own deformation energy to overcome the impact of the hot air.

[0054] like Figure 18 and Figure 19 As shown, as an optimization of the embodiment, a folding plate 66 is hinged to the third shaft 55. The folding plate 66 corresponds one-to-one with the guide member 45. There are two folding plates 66, which are symmetrically arranged on both sides of the guide member 45. Each folding plate 66 includes a first connecting plate 67 hinged to the third shaft 55. A second connecting plate 68 is hinged to the free end of the first connecting plate 67. The hinge point between the second connecting plate 68 and the first connecting plate 67 is located above the third shaft 55. The free end of the second connecting plate 68 is hinged to the inner bottom surface of the air distribution box 6. The guide member 45 is driven by the second motor 65 to reciprocate, and the third shaft 55 swings synchronously. The folding plates 66 on both sides expand or contract, expanding the air distribution range of the guide member 45 and improving the air distribution effect.

[0055] like Figure 20 and Figure 21As shown, as an optimization of the embodiment, considering the gap between the first housing 2 and the support chain 37, when the hot air dries the adhesive film, some wind may enter through this gap, or the hot air from adjacent housings may intrude into each other. A fifth support plate 69 is installed on the inner side wall of the first housing 2. A first shaft 44 is hinged to the fifth support plate 69. A guide 45 is installed on the first shaft 44. A telescopic rod 70 is hinged to the second shaft 51 of the guide 45. A cylinder seat 71 is hinged to the tail end of the telescopic rod 70. The cylinder seat 71 is connected to the first housing 2. By setting the telescopic rod 70, the tilt angle of the guide 45 can be adjusted, thereby changing the gap between the guide 45 and the adhesive film. This ensures that while the hot air dries the adhesive film, it prevents wind from entering the first housing 2 and prevents the hot air from intruding into each other from adjacent housings.

[0056] like Figure 22 and Figure 23 As shown, as an optimization of the embodiment, a fixed cover 72 is installed on the first housing 2, and an openable cover 73 is installed on the fixed cover 72. A sleeve 74 is installed on the cover 73. A pressure cap 75 is fastened to the upper end of the sleeve 74. A first connecting rod 76 is hinged to the pressure cap 75. A third bearing seat 77 is hinged to the waist of the first connecting rod 76. The third bearing seat 77 is located on the fixed cover 72. A pressure rod 78 is hinged to the tail end of the first connecting rod 76. The side wall of the pressure rod 78 is guided by a limiting plate 79, so that the pressure rod 78... With its end facing upwards, a compression spring 80 is installed on the bottom surface of the first connecting rod 76 on the side with the pressure rod 78. The compression spring 80 uses the seesaw principle to make the first connecting rod 76 continuously press the cover 75 downwards.
