Description

Technical Field

[0001] This utility model belongs to the technical field of casting equipment, and specifically relates to a casting nozzle. Background Technology

[0002] Thin film production processes include blowing, coating, and casting. Among these, casting is widely used, and it is mainly divided into solution casting and melt casting. In equipment for producing thin films using solution casting, the casting nozzle and the steel belt used to transport the film are the core components. Controlling the distance between the casting nozzle and the steel belt is crucial to ensuring the uniformity of the film thickness.

[0003] In existing technologies, the casting nozzle itself is generally not adjustable; the distance between the casting nozzle and the steel strip is adjusted by adjusting the height of the nozzle's mounting bracket. However, this method has a significant drawback: adjusting the mounting bracket height only adjusts the overall height of the casting nozzle. The flatness of the steel strip surface is affected by various factors after long-term use, such as wear of the conveyor rollers, deformation of the steel strip under stress, and wear of the steel strip itself. This means the distance between the steel strip and the casting nozzle may not remain within the acceptable range. However, casting equipment is generally long, with many conveyor rollers and a long steel strip. Furthermore, replacing parts requires significant equipment debugging time, increasing maintenance costs considerably. Therefore, finding a way to match the casting nozzle to a steel strip with poor flatness simply by adjusting the nozzle has become a pressing problem for casting equipment. Utility Model Content

[0004] This invention provides a casting nozzle to solve the technical problem in the prior art that the casting nozzle itself cannot be adjusted and is difficult to match with steel strips with poor flatness. This utility model includes: a vertical plate; An inclined plate is provided opposite to the vertical plate. The bottom surface of the inclined plate has a groove, and the top surface of the groove has a plurality of first threaded holes and a plurality of through holes. Two end plates are respectively located at both ends of the vertical plate and the inclined plate; An insert is provided in the groove, and the side of the insert opposite the inclined plate has at least one sealing groove. The top surface of the insert has a plurality of second threaded holes, and the positions of the second threaded holes correspond to the through holes. A sealing strip is provided within the sealing groove; Several fastening bolts pass through the through hole and are connected to the second threaded hole, respectively; Several adjusting bolts are connected to the first threaded hole, and the ends of the adjusting bolts abut against the top surface of the insert.

[0005] This invention uses fastening bolts to fix the insert to the bottom surface of the inclined plate, and then adjusts the bolts to push out the insert, causing local deformation of the insert, which can make the spacing between the insert and the steel strip more matched.

[0006] Furthermore, the outer surfaces of the upright plate and the inclined plate are provided with a number of weight-reducing grooves at intervals. The beneficial effects of this step are that the weight-reducing grooves themselves can reduce the self-weight of the upright plate and the inclined plate, and the excess material between the weight-reducing grooves forms structural reinforcing ribs for the upright plate and the inclined plate, which can also prevent the upright plate and the inclined plate from deforming.

[0007] Furthermore, the bottom corner of the strip facing the upright plate is a rounded corner, which has the following advantages: the rounded corner facilitates the flow of slurry.

[0008] Furthermore, each of the weight-reducing grooves at the bottom of the inclined plate is provided with at least one fastening bolt and at least one adjusting bolt. The beneficial effect of this step is to maintain the basic fastening and adjusting structure.

[0009] Furthermore, each of the fastening bolts is provided with adjusting bolts on both sides, which has the following advantages: improving the ability to adjust the flatness of the insert.

[0010] Furthermore, countersunk holes are provided on the inclined plate at the positions corresponding to the fastening bolts, and the heads of the fastening bolts are all inside the countersunk holes. The beneficial effect of this step is that it distinguishes the fastening bolts from the adjusting bolts, thus avoiding affecting the adjustment effect.

[0011] Furthermore, both the fastening bolt and the adjusting bolt are fine-pitch bolts. The advantages of this step are that the smaller the pitch, the higher the adjustment accuracy and the lower the adjustment difficulty.

[0012] The beneficial effects of this utility model are: This application sets an insert strip on the bottom surface of the inclined plate, so that the bottom surface of the insert strip replaces the bottom surface of the inclined plate to form a casting gap with the surface of the steel strip. The insert strip can be adjusted at multiple points by tightening bolts to pull the insert strip and adjusting bolts to push the insert strip, so that the interval between the bottom surface of the insert strip and the surface of the steel strip remains basically consistent, thereby obtaining a good film product.

[0018] Furthermore, the terms "first," "second," etc., 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. In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly defined.

[0019] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0021] Implementation of this application, for example Figures 1-3 As shown, this application provides a casting nozzle.

[0022] This application includes: a vertical plate 1; An inclined plate 2 is disposed opposite to the upright plate 1. A groove 21 is provided on the bottom surface of the inclined plate 2, and a plurality of first threaded holes and a plurality of through holes are provided on the top surface of the groove 21. Two end plates 3 are respectively located at the ends of the vertical plate 1 and the inclined plate 2. The inclined plate 2 is located in front of the vertical plate 1 (with the direction of rotation of the steel strip 8 as the front). The end plates 3, the vertical plate 1 and the inclined plate 2 form a groove-shaped structure that is larger at the top and smaller at the bottom. The slurry is stored inside. The slurry flows out from the bottom gap of the inclined plate 2 and the vertical plate 1 and flows onto the steel strip 8 below. The structure that is larger at the top and smaller at the bottom can reduce the outflow of slurry while ensuring the slurry capacity, so as to control the casting effect. The insert 4 is disposed in the groove 21. The insert 4 has at least one sealing groove on one side opposite to the inclined plate 2. The top surface of the insert 4 has several second threaded holes, which correspond to the positions of the through holes. The two end faces and one side face of the insert 4 fit into the groove 21. It is worth noting that the thickness of the insert 4 should not be too thick. If the insert 4 is too thick, its rigidity will be too high, and the fastening bolt 7 and adjusting bolt 6 will be unable to overcome its rigidity and deform it. Sealing strip 5 is disposed within the sealing groove; Several fastening bolts 7 are respectively passed through the through hole and connected to the second threaded hole; Several adjusting bolts 8 are respectively connected to the first threaded hole, and the end of the adjusting bolt abuts against the top surface of the insert 4.

[0023] This application uses fastening bolts 7 to fix the insert 4 in the groove 21 on the bottom surface of the inclined plate 2, and then uses adjusting bolts 6 to push out the insert 4, causing local deformation of the insert 4, which can make the spacing between the insert 4 and the steel strip 8 more matched.

[0024] For example, if there is a dent or deformation at a certain point on the conveyor roller, the corresponding deformation point on the steel strip 8 will also be dented. Since the steel strip 8 itself has a certain degree of rigidity, the deformation of the steel strip 8 will be a smooth transition, rather than an abrupt deformation. Similarly, the insert 4 also has a certain degree of rigidity, and under the action of the adjusting bolt 6 and the fastening bolt 7, its deformation will also be a smooth transition. In this way, the insert 4 can match the steel strip 8. It should be noted that the deformation of the conveyor roller is generally wear after long-term use, and it is circumferential wear, not single-point wear. Therefore, its impact on the steel strip 8 is continuous, not intermittent.

[0025] Based on the above technical solution, the outer surfaces of the upright plate 1 and the inclined plate 2 are provided with a number of weight-reducing grooves 22 at intervals. The weight-reducing grooves 22 can reduce the weight of the upright plate 1 and the inclined plate 2, and the excess material between the weight-reducing grooves 22 forms the structural reinforcing ribs of the upright plate 1 and the inclined plate 2, which can also prevent the upright plate 1 and the inclined plate 2 from deforming.

[0026] Based on the above technical solution, the bottom corner of the inlay 4 facing the upright plate 1 is a rounded corner. The distance between the rounded corner and the steel strip is relatively large, so that a relatively full amount of slurry can remain inside. During the casting process, the slurry can be continuously supplied, ensuring the quality of the slurry casting.

[0027] Based on the above technical solution, each of the weight-reducing grooves 22 at the bottom of the inclined plate 2 is provided with at least one fastening bolt 7 and at least one adjusting bolt 6, which can maintain the basic fastening structure and adjusting structure.

[0028] Based on the above technical solution, each of the fastening bolts 7 is provided with adjusting bolts 6 on both sides. This arrangement allows the fastening bolts 7 and adjusting bolts 6 to be set alternately, which can improve the ability to adjust the flatness of the insert 4.

[0029] Based on the above technical solution, countersunk holes are provided at the positions of the inclined plate 2 corresponding to the fastening bolts 7, and the heads of the fastening bolts 7 are all inside the countersunk holes. In order to facilitate the adjustment of the position of the insert 4 and simplify the tools, the fastening bolts 7 and the adjusting bolts 6 must be of the same specification. However, if the fastening bolts 7 and the adjusting bolts 6 are mistakenly distinguished during the adjustment process, it will lead to a longer adjustment time and reduced efficiency. In addition, the fastening bolts 7 can be tightly attached to the inclined plate 2, so it is necessary to distinguish the fastening bolts 7 and the adjusting bolts 6 by setting countersunk holes to avoid affecting the adjustment efficiency.

[0030] Based on the above technical solution, both the fastening bolt 7 and the adjusting bolt 6 are fine-pitch bolts. The smaller the pitch, the higher the adjustment accuracy and the lower the adjustment difficulty (under the same tightening amplitude, the elongation / retraction distance of the fine-pitch bolt is smaller, making the adjustment more accurate). In addition, the heads of the fastening bolt 7 and the adjusting bolt 6 can be provided with square heads, controlling the tightening angle to 90° on one side, which is more convenient for operation.

[0031] In the above-mentioned process, a locking nut can also be installed on the adjusting bolt 6. After the adjusting bolt 6 is adjusted, the locking nut is used to fix the adjusting bolt 6 in place to prevent vibration and other factors from affecting the adjustment accuracy.

[0032] Numerous specific details are set forth in this specification. However, it will be understood that embodiments of this invention may be practiced without these specific details. In some instances, well-known methods, structures, and techniques have not been shown in detail so as not to obscure the understanding of this specification.

Furthermore, without contradiction, those skilled in the art can combine and integrate the different embodiments or examples described in this specification, as well as the features of the different embodiments or examples.
