Description

Technical Field

[0001] The utility model belongs to the technical field of support frames, and in particular relates to an oven air nozzle support structure and a support frame. Background Art

[0002] In the wet process of diaphragm production, the diaphragm material needs to be made through a series of complex steps, including the secondary transverse stretching of the film. The width of the secondary transverse stretched film is relatively wide, and the length of the nozzle used to dry and treat the film in the corresponding oven also needs to be increased to ensure uniform treatment of the film. At present, the scissor-type nozzle structure is more common in such applications. Its design is to control the wind speed and air volume by adjusting the opening and closing of the nozzle mouth, so as to achieve uniform drying of the film. However, as the length of the nozzle increases, its own rigidity is often not enough to support the structure with its bottom suspended, especially during long-term operation. This structural defect causes the nozzle to shake during use, affecting the uniformity of the air outlet. In addition, the lateral temperature distribution of the nozzle may also vary due to the shaking, which in turn affects the drying effect and quality stability of the film. These problems are unacceptable in the process of producing high-quality diaphragm materials because they directly affect the performance and reliability of the final product. Utility Model Content

[0035] The following will clearly and completely describe the concept, specific structure and technical effects of the utility model in combination with the embodiments and drawings, so as to fully understand the purpose, characteristics and effects of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of them. Based on the embodiments of the utility model, other embodiments obtained by technicians in this field without creative work are all within the scope of protection of the utility model. In addition, all the connection / connection relationships involved in the patent do not refer to the direct connection of components, but refer to the formation of a better connection structure by adding or reducing connection accessories according to the specific implementation situation. The various technical features in the creation of the utility model can be combined interchangeably without conflicting with each other.

[0036] In the wet-process diaphragm production process, the width of the secondary horizontally stretched film is relatively wide, and the corresponding length of the oven nozzle also needs to be very long. Generally, the length of the oven nozzle will reach 8-9m. Especially when a scissor-type nozzle structure is adopted, even if a hanging rope is set at the front section of the scissor-type nozzle to stabilize the nozzle, the bottom of the nozzle is suspended in the air and the nozzle is relatively long, and the nozzle itself is not rigid enough. The nozzle will still shake during operation, thereby affecting the uniformity of air output and the lateral temperature difference of the nozzle, resulting in unstable product quality.

[0037] The utility model discloses an oven air nozzle support structure for supporting the air nozzle to improve the stability of the air nozzle during operation. During maintenance, the scissor-type air nozzle needs to be opened to occupy space. At this time, the support structure can be moved to provide sufficient space for the maintenance of the scissor-type air nozzle.

[0038] Reference Figure 1-2 A support structure for an oven air nozzle comprises a sliding assembly 1, a supporting assembly 2 and a driving assembly 3; the supporting assembly 2 comprises a first supporting portion 21 and a second supporting portion 22, one end of the first supporting portion 21 is connected to the sliding assembly 1, and the other end of the first supporting portion 21 is provided with a "wedge" structure 211 for supporting the second supporting portion 22, and the second supporting portion 22 is away from the side of the first supporting portion 21 for supporting the oven air nozzle; the driving assembly 3 is connected to and drives the first supporting portion 21, so that the second supporting portion 22 is lifted and lowered relative to the first supporting portion 21 through the "wedge" structure 211. It should be noted that the driving component 3 drives the first support part 21 to move. When the second support part 22 is displaced upward relative to the first support part 21 through the "wedge" structure 211, the support structure will continuously increase the support height until the support height is adjusted to the specified position; when the second support part 22 is displaced downward relative to the first support part 21 through the "wedge" structure 211, since a suspension rope is provided at the front end of the air nozzle, the air nozzle is always under tension at this time. Therefore, it is only necessary to separate the contact between the second support part 22 and the "wedge" structure 211 to disconnect the support, and then move the support structure away. It can be understood that when the air nozzle is in operation, the support structure of this solution can provide stable support, and can also be easily moved, without occupying the space required for air nozzle maintenance.

[0039] In some embodiments, reference Figure 3, the second support part 22 includes: a support plate 221, a support rod 222 and a tightening block 223; the support plate 221 is used to support the oven air nozzle, one end of the support rod 222 is connected to the support plate 221, and the other end is connected to the tightening block 223, the tightening block 223 is tightened with the "wedge" structure 211 and supports the support plate 221 through the support rod 222. It should be noted that the support plate 221 is fixedly connected to the oven air nozzle, specifically, bolt connection, welding and the like can be adopted, which are not limited here. The "wedge" structure 211 is an inclined surface set on the first support part 21. When the driving component 3 drives the first support part 21 to move, the tightening block 223 can move along the inclined surface, so that the second support part 22 produces a lifting displacement. Specifically, the orientation of the inclined surface can be along the direction in which the driving component 3 drives the first support part 21 to move, that is, the inclined surface can be along the forward driving direction or the reverse driving direction, and can drive the first support part 21 and the second support part 22 to produce lifting displacement to meet the purpose of this solution.

[0040] In some embodiments, continue to refer to Figure 3 The driving assembly 3 includes an adjusting screw 31 and an adjusting fixed seat 32. The adjusting screw 31 is rotatably connected to the first support portion 21, and the adjusting screw 31 is transmission-connected to the adjusting fixed seat 32. The adjusting screw 31 is arranged between the first support portion 21 and the adjusting fixed seat 32. Specifically, the adjusting screw 31 is preferably a trapezoidal screw. When the trapezoidal screw is adjusted to rotate and drive the first support portion 21 and the second support portion 22 to complete the support, the supporting structure can stably stay in the current position by utilizing the self-locking characteristics of the trapezoidal screw, thereby ensuring the stability of the nozzle operation.

[0041] Reference Figure 1-2 In some embodiments, a drive shaft is provided on the other side of the adjustment fixing seat 32, and the drive shaft is connected to the adjustment screw 31. Specifically, the drive shaft is connected to the adjustment screw 31 through a coupling. When in use, the drive shaft can be driven to rotate manually or with the help of a motor, and the drive shaft drives the adjustment screw 31 to rotate, thereby driving the first support part 21 to reciprocate.

[0042] In some embodiments, reference Figure 3, the length of the support rod 222 is adjustable, so as to adjust the distance between the support plate 221 and the top block 223. When the lifting displacement generated by the first support part 21 and the second support part 22 is not enough to support the nozzle to a predetermined height, the distance between the support plate 221 and the top block 223 is adjusted by adjusting the length of the support rod 222, so that the support height reaches the expected position. Specifically, the support rod 222 is a screw rod, which passes through the support plate 221, and locking nuts are provided at both ends of the support plate 221, and the length of the screw rod is adjusted by adjusting the locking nuts.

[0043] In some embodiments, the tightening block 223 is movably connected to the support rod 222 via a connecting shaft 224. The tightening block 223 can rotate around the support rod 222. When the angle between the inclined surface of the "wedge"-shaped structure 211 and the horizontal plane changes, the tightening block 223 can make adaptive adjustments, so that the tightening block 223 always supports the second support portion 22 in the vertical direction, further improving the stability of the support.

[0044] In some embodiments, in order to ensure that the supporting structure has sufficient mechanical properties, the supporting structure is generally made of steel. Therefore, when the top tightening block 223 contacts and displaces the "wedge" structure 211, a buffer 2231 is provided on the side of the top tightening block 223 close to the "wedge" structure 211 to prevent metals from rubbing against each other. The top tightening block 223 is supported on the "wedge" structure 211 by the buffer 2231. In addition, since the working condition of the supporting structure is generally a high temperature environment, the buffer 2231 is made of a high temperature resistant material, preferably a high temperature resistant plastic plate.

[0045] Reference Figure 4 In some embodiments, the sliding component 1 includes a sliding part 11 disposed on the first supporting part 21 and a slide rail 12 cooperating with the sliding part 11. Specifically, the sliding part 11 includes a clamping part 111 and a pulley 112, wherein the pulley 112 is disposed on both sides of the clamping part 111, and the clamping part 111 is embedded in the slide rail 12, and the outer side of the clamping part 111 and the inner side of the slide rail 12 can abut against each other. When the driving component 3 drives the first supporting part 21 and the second supporting part 22 to displace, when the first supporting part 21 moves along the slide rail 12, the pulley 112 cooperates with the slide rail 12 to reduce the friction between the first supporting part 21 and the ground and enables the first supporting part 21 to move in a predetermined direction, thereby improving the support stability of the support structure.

[0046] The utility model also discloses an oven air nozzle support frame, comprising the above-mentioned support structure. Specifically, the air nozzle support frame comprises a plurality of the support structures, and the air nozzle support frame formed by the plurality of the support structures has a more stable support effect to meet production requirements under more working conditions.

[0047] The above is a specific description of the preferred implementation of the utility model, but the invention of the utility model is not limited to the described embodiments. Technical personnel familiar with the field can also make various equivalent deformations or substitutions without violating the spirit of the utility model. These equivalent deformations or substitutions are all included in the scope defined by the claims of this application.
