According to an embodiment of the present invention, the flexible air supply heat exchange unit for the film production line oven includes a box 10, a rail 20, a transmission chain clamp 30, a first air supply pipe 40, a second air supply pipe 50, and a hot air supply mechanism 60. The track 20 is arranged in the box body 10, the transmission chain clamp 30 is arranged on the track 20, and the transmission chain clamp 30 is used for clamping the side part of the film 70 and synchronously driving the film 70 to run. The first air supply pipe 40 is disposed in the box 10 and above the film 70, a plurality of first air outlet holes 41 (as shown in fig. 5) are disposed on a side surface of the first air supply pipe 40 facing the film 70, and at least one first nozzle 42 is disposed on the rest of the first air supply pipe 40. The second air supply pipe 50 is arranged in the box body 10 and is positioned below the film 70, a plurality of second air outlet holes 51 are arranged on the side surface of the second air supply pipe 50 facing the film 70, and at least one second nozzle 52 is arranged on the rest part of the second air supply pipe 50. The hot air supply mechanism 60 is respectively communicated with the first air supply pipe 40 and the second air supply pipe 50.
In the flexible air supply heat exchange unit of the film production line oven, when the flexible air supply heat exchange unit works, hot air supplied by the hot air supply mechanism 60 is respectively output to the first air supply pipe 40 and the second air supply pipe 50, one part of the hot air entering the first air supply pipe 40 is discharged through the first air outlet 41, and the other part of the hot air is discharged through the first nozzle 42; a part of the hot air entering the second blast pipe 50 is discharged through the second air outlet hole 51, and the other part of the hot air is discharged through the second nozzle 52; the hot air discharged from the first air outlet 41 is used for contacting one side surface of the film 70 for heat exchange, and the hot air discharged from the second air outlet 51 is used for contacting the other side surface of the film 70 for heat exchange, namely, the side surface of the first air supply pipe 40 facing the film 70, the side surface of the second air supply pipe 50 facing the film 70, and the area between the two rails 20 are equivalent to a process thermal field 101 of the film 70, and the rest area inside the box body 10 is equivalent to an environment thermal field 102 surrounding the process thermal field 101; the hot air exhausted from the first nozzle 42 and the hot air exhausted from the second nozzle 52 both directly enter the environmental thermal field 102 to offset the heat dissipation effect of the box body 10 and establish a peripheral environment in accordance with the film process temperature, thereby cutting off the main path of outward dissipation of the heat of the process thermal field 101, so that the heat of the process thermal field 101 is not easy to dissipate outward through the environmental thermal field 102, and on the premise of ensuring better heat exchange effect on the film 70, the first air outlet 41 and the second air outlet 51 can both output air at a lower air speed, thereby not only ensuring the processing quality of the film 70, but also avoiding the defect of physical deformation caused by overlarge air speed.
In one embodiment, to reduce noise, the first and second blower tubes 40 and 50 each include, but are not limited to, being configured as a plenum box. The plenum box both allows airflow therethrough and effectively prevents or attenuates the transmission of acoustic energy to the exterior of the enclosure 10.
It should be noted that the first nozzle 42 and the second nozzle 52 are used for discharging the hot air inside the pipe body to the ambient thermal field 102, so the specific caliber size, shape, number and arrangement thereof are not limited herein, and can be flexibly adjusted and set according to actual requirements. As an example, the first outlet 42 and the second outlet 52 are both provided as air outlets, for example, as shown, and the aperture of the air outlet is usually set larger than the apertures of the first outlet 41 and the second outlet 51, but may be set smaller than the apertures of the first outlet 41 and the second outlet 51.
It should be noted that the remaining portion of the first air supply duct 40, which is provided with at least one first nozzle 42, refers to the area of the first air supply duct 40 other than the side facing the film 70, such as the side of the first air supply duct 40 opposite to the film 70, and/or the side of the first air supply duct 40 perpendicular to the film 70, and/or the end surface of the first air supply duct 40 away from the distribution box 62.
It will also be appreciated that the provision of the remaining portion of the second supply duct 50 with at least one of the second jets 52 means that the area of the second supply duct 50 other than the side facing the membrane 70, in particular the side of the second supply duct 50 facing away from the membrane 70, and/or the side of the second supply duct 50 perpendicular to the membrane 70, and/or the end face of the second supply duct 50 remote from the distribution box 62.
In one embodiment, the sum of the air outlet areas of all the first air outlet holes 41 of the first air delivery pipe 40 is defined as S1, and the sum of the air outlet areas of all the first nozzles 42 of the first air delivery pipe 40 is defined as S2; the sum of the air outlet areas of all the second air outlets 51 of the second air delivery pipe 50 is defined as S3, and the sum of the air outlet areas of all the second nozzles 52 of the second air delivery pipe 50 is defined as S4; s2>20% (S1 + S2); s4>20% (S3 + S4). Thus, the temperature of the ambient thermal field 102 is controllable, so that the heat of the process thermal field 101 is not easily dissipated to the outside through the ambient thermal field 102.
As an example, S2>50% (S1 + S2), S4>50% (S3 + S4).
It should be noted that the first air outlet 41 and the second air outlet 51 include, but are not limited to, circular holes, triangular holes, square holes, pentagonal holes, hexagonal holes, and the like, and may be holes with regular shapes or holes with irregular shapes, and are flexibly adjusted and set according to actual requirements.
In one embodiment, when the first outlet vent 41 and the second outlet vent 51 are configured as circular holes, the aperture of each of the first outlet vent 41 and the second outlet vent 51 is in the range of 1mm to 10mm. Specifically, the aperture of each of the first air outlet 41 and the second air outlet 51 is in a range of 2mm to 3mm, which includes but is not limited to 2mm, 2.5mm, and 3mm. Therefore, the first air outlet 41 and the second air outlet 51 have smaller apertures, so that soft air outlet can be realized, and the defect of physical deformation of the film 70 is not easy to cause.
Similarly, when the first air outlet 41 and the second air outlet 51 are configured as other shapes of holes, the air output of the first air outlet 41 and the second air outlet 51 can be adjusted by adjusting the sizes of the first air outlet 41 and the second air outlet 51, so as to achieve soft air output; on the other hand, when the sizes of the first air outlet 41 and the second air outlet 51 are adjusted, the ratio between S2 and S1+ S2 and the ratio between S4 and S3+ S4 can be adjusted, so that the temperature of the process thermal field and the temperature of the ambient thermal field can be better controlled.
Referring to fig. 1, 3 and 4, in one embodiment, the first air supply pipe 40 is provided in plurality, and all the first air supply pipes 40 are sequentially arranged at intervals along the running direction (e.g., the direction of arrow S in fig. 1) of the film 70. The second blowing duct 50 is plural, and all the second blowing ducts 50 are sequentially arranged at intervals along the running direction of the film 70. The second blowing duct 50 is provided corresponding to the first blowing duct 40. Thus, the plurality of first air supply pipes 40 are adopted to output hot air outwards to one side surface of the film 70 through the first air outlet holes 41, and the plurality of second air supply pipes 50 are adopted to output hot air outwards to the other side surface of the film 70 through the second air outlet holes 51, so that the film 70 has a good heating treatment effect on each part along the longitudinal direction of the film 70.
Referring to fig. 1, 3 and 4, in one embodiment, the interval between any two adjacent first blowing pipes 40 is defined as a first interval passage 44, and the first blowing pipes 40 are provided with a first damping member 43 positioned in the first interval passage 44. The interval between any two adjacent second blowing ducts 50 defines a second interval passage 54, and the second blowing ducts 50 are provided with a second damping member 53 positioned in the second interval passage 54. Thus, in the process that hot air entering the process thermal field 101 is subjected to heat exchange with the film 70 and then enters the environment thermal field 102 through the first spacing channel 44 and the second spacing channel 54, the first damping member 43 and the second damping member 53 can provide certain resistance to reduce the speed of the hot air entering the environment thermal field 102, that is, the process thermal field 101 and the environment thermal field 102 can be isolated as far as possible, so that the heat of the process thermal field 101 is not easily transferred to the environment thermal field 102, and on the premise of ensuring a good heat exchange effect on the film 70, the first air outlet 41 and the second air outlet 51 can both output air at a low air speed, in other words, soft air output, so that the processing quality of the film 70 can be ensured, and the defect of physical deformation caused by an overlarge air speed can be avoided.
Referring to fig. 1, in one embodiment, the first air supply pipe 40 is provided with first damping members 43 at two opposite sides thereof, and a distance between the first damping member 43 and the film 70 at one side of the first air supply pipe 40 is different from a distance between the first damping member 43 and the film 70 at the other side of the first air supply pipe 40. In addition, the second air supply pipe 50 is provided with second damping members 53 at opposite sides thereof, and a distance between the second damping member 53 and the film 70 at one side of the second air supply pipe 50 is different from a distance between the second damping member 53 and the film 70 at the other side of the second air supply pipe 50. In this way, for any two adjacent first air supply pipes 40, two first damping members 43 arranged at intervals up and down are arranged in the first partition passage 44, and the two first damping members 43 are combined with each other to provide a certain resistance to reduce the speed of the hot air of the process thermal field 101 entering the environmental thermal field 102; similarly, for any two adjacent second blowing pipes 50, two second damping members 53 arranged at intervals up and down are arranged in the second partition passage 54, and the two second damping members 53 are combined with each other to provide a certain resistance to reduce the speed of the hot air in the process thermal field 101 entering the ambient thermal field 102.
Specifically, the first damping member 43 and the second damping member 53 are all disposed as a plate, a rod or a cylinder, as long as they can block the airflow.
Referring to fig. 1 and 4, in addition, in an embodiment, the first damping member 43 is disposed to extend along one end of the first air supplying pipe 40 to the other end of the first air supplying pipe 40, and plays a good role in blocking flow for each position of the first air supplying pipe 40 in the axial direction. Similarly, the second damper 53 is provided to extend along one end of the second air blowing duct 50 to the other end of the first air blowing duct 40, and provides a good flow-blocking effect to each portion in the axial direction of the second air blowing duct 50.
It should be noted that, along the axial direction, the cross-sectional shapes of the first air delivery pipe 40 and the second air delivery pipe 50 include, but are not limited to, square, circle, ellipse, triangle, pentagon, hexagon, etc., and may be regular shapes or irregular shapes. It is understood that, when the first air delivery duct 40 has a square or circular cross-section in the axial direction, the first air delivery duct 40 is a square or circular duct, respectively.
Referring to fig. 1 again, in an embodiment, an interval between any two adjacent first air delivery pipes 40 is defined as a first interval channel 44, the first interval channel 44 is provided with first diverging sections 441 with gradually increasing intervals along the air flow direction, and the pipe walls forming the first diverging sections 441 are provided with first nozzles 42; the interval between any two adjacent second blast pipes 50 is defined as a second interval channel 54, the second interval channel 54 is provided with second diverging sections 541 the distance of which gradually increases along the direction of the wind flow, and the pipe walls forming the second diverging sections 541 are provided with second nozzles 52. Thus, for the first divergent section 441, the first nozzles 42 are disposed on the walls of the tubes forming the first divergent section 441, and the directions of the hot wind sprayed out from the first nozzles 42 are mutually crossed, so as to form a barrier, and provide a certain resistance to reduce the flow of the hot wind in the process thermal field 101 to the ambient thermal field 102 through the first divergent section 441. Similarly, in the second divergent section 541, the pipe walls forming the second divergent section 541 are all provided with the second nozzles 52, and the directions of the hot wind sprayed outwards by the second nozzles 52 are mutually crossed, so that a barrier can be formed, and the hot wind which provides a certain resistance and reduces the process thermal field 101 flows to the ambient thermal field 102 through the second divergent section 541.
Referring to fig. 1, in one embodiment, the surface of the first air supply pipe 40 facing away from the film 70 is defined as a first back surface, two opposite side portions of the first back surface are respectively provided with a first inclined surface 45 or a first arc surface, and the first nozzle 42 is further disposed on the first inclined surface 45 or the first arc surface. Thus, for any two adjacent first air delivery pipes 40, two first inclined surfaces 45 or two first arc-shaped surfaces can be combined to form the first diverging section 441.
Referring to fig. 1, in one embodiment, the surface of the second air duct 50 facing away from the film 70 is defined as a second back surface, two opposite sides of the second back surface are respectively provided with a second inclined surface 55 or a second arc-shaped surface, and the second nozzle 52 is further disposed on the second inclined surface 55 or the second arc-shaped surface.
