[0002] The existing evaporation equipment needs to adjust the height of the evaporation tank according to the site condition and actual needs before being put into use, that is, the upper surface (mainly the crucible) of the evaporation tank is adjusted to a proper height position so that it is at the most suitable distance from the cooling main roller, thereby ensuring the evaporation quality; in addition, the height position of the upper surface of the evaporation tank will gradually decrease over time during the working process, and thus needs to be adjusted regularly. In the prior art, the evaporation tank is composed of multiple layers, such as an upper ceramic layer, an upper graphite carbon felt layer, a graphite electrode, a lower ceramic layer, a lower graphite carbon felt layer, and a white cotton layer arranged in order from top to bottom, among which the main function of the white cotton layer is to adjust the height of the graphite electrode and thus the height of the upper surface of the entire evaporation tank. By setting white cotton layers with different thicknesses or increasing / decreasing the number of white cotton layers, the height of the evaporation tank can be adjusted to meet the working needs.

[0003] In the process of implementing the utility model, the inventors have found that at least the following problems exist in the prior art:

[0004] When the height is adjusted by the white cotton layer, the height can only be adjusted "step by step" because the white cotton layer usually has a specific thickness, and thus cannot be continuously adjusted without interruption, which sometimes cannot meet the use requirements. Therefore, how to continuously adjust the height of the evaporation tank is a problem to be solved. CONTENT OF THE UTILITY MODEL

[0005] The utility model embodiment provides a kind of adjustable evaporation tank to solve the problem that the height of evaporation tank in existing evaporation equipment cannot be continuously adjusted.

[0006] To achieve the above purpose, on the one hand, the utility model embodiment provides a kind of adjustable evaporation tank, which comprises a white cotton layer and an evaporation tank bottom that are stacked and laid, and further comprises an adjusting pad and an adjusting bolt arranged between the white cotton layer and the evaporation tank bottom; the adjusting pad is horizontally arranged in a flat plate structure, and a vertical screw hole is formed in the lower surface of the adjusting pad; the threaded end of the adjusting bolt is screwed into the adjusting pad from bottom to top through the screw hole, and the nut of the adjusting bolt is abutted on the upper surface of the evaporation tank bottom; the top surface of the adjusting pad is in close contact with the bottom surface of the white cotton layer.

[0007] Further, four screw holes are arranged on the adjusting pad, and the four screw holes are distributed along a rectangular array at four corner points of the adjusting pad.

[0008] Further, the horizontal projection of the adjusting pad is a rectangle.

[0009] Further, the adjusting pads are multiple, and the side edges of the adjacent adjusting pads do not contact each other.

[0010] Further, the material of the adjusting bolt is high-temperature bolt steel, or high-temperature alloy steel, or heat-resistant steel.

[0011] Further, the screw hole is a blind hole.

[0012] Further, in the adjusting bolt, the side of the nut away from the threaded end is a plane.

[0013] Further, the adjusting bolt is a hexagonal head bolt.

[0014] Further, the white cotton layer is multiple, and the multiple white cotton layers are arranged at intervals, and each adjusting pad under each white cotton layer does not contact other white cotton layers.

[0015] Further, the screw hole and the length of the adjusting bolt in the screwing range are 0.5mm-15mm.

[0016] The above technical solution has the following beneficial effects:

[0017] In the technical solution, in addition to the white cotton layer, adjusting pads are arranged, and the height of the adjusting pad can be changed by rotating the adjusting bolt. Since the rotation angle of the adjusting bolt can be continuously adjusted, the height of the evaporation tank is also continuously adjusted, thereby meeting different use requirements on site.

[0018] In addition, the technical solution also has the following characteristics:

[0019] The existing adjustment method through the white cotton layer can only change the overall height of the graphite electrode, and cannot adjust the height of each corner point, so horizontal adjustment cannot be performed. After the technical solution is adopted, since the four corners of the adjusting pad are connected with the adjusting bolt, the horizontal adjustment of the upper surface of the evaporation tank can be performed by adjusting the adjusting bolt at different positions.

[0025] The technical scheme in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all the other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0026] As shown in Figure 1 , Figure 2 , the embodiment of the present application provides an adjustable evaporation tank, which comprises a white cotton layer 10 and an evaporation tank bottom 30 laid in layers, and further comprises an adjusting pad 20 and an adjusting screw bolt 40 arranged between the white cotton layer 10 and the evaporation tank bottom 30. The adjusting pad 20 is horizontally arranged in a flat plate structure, and a vertical screw hole 21 is formed in the lower surface of the adjusting pad 20. The threaded end of the adjusting screw bolt 40 is screwed into the adjusting pad 20 from below, and the nut of the adjusting screw bolt 40 is abutted on the upper surface of the evaporation tank bottom 30. The top surface of the adjusting pad 20 is attached to the bottom surface of the white cotton layer 10.

[0027] To solve the foregoing problems, in the embodiment of the present application, in addition to retaining the original white cotton layer 10, an adjusting pad 20 is further arranged. When adjusting the height, the height can be first adjusted to the vicinity of the expected height by arranging the white cotton layer 10, and then the adjusting screw bolt 40 below the adjusting pad 20 is rotated to move the adjusting pad 20 up and down in the direction indicated by the arrow in the middle, so as to adjust the position of the graphite electrode, and finally change the position of the upper surface of the evaporation tank. By changing the rotation direction of the adjusting screw bolt 40, the adjusting pad 20 can be moved in the opposite direction. In this process, since the rotation angle of the adjusting screw bolt 40 can be continuously adjusted, the height of the evaporation tank is also continuously adjusted, rather than being adjusted one gear at a time as in the prior art, so as to meet different use requirements on site. Of course, if necessary, the white cotton layer 10 can not be arranged, and the adjusting pad 20 and the adjusting screw bolt 40 can be directly arranged below the lower graphite carbon felt layer, but in order to realize rapid adjustment, the white cotton layer 10 is preferably retained. Figure 2

[0028] ​Furthermore, the adjusting shim 20 is provided with four screw holes 21, which are distributed in a rectangular array at the four corners of the adjusting shim 20. The even distribution of the four adjusting bolts 40 ensures that the adjusting shim 20 is more stable. At the same time, by adjusting the adjusting bolts 40 at different positions, the levelness of the shim 20 can be adjusted, thereby achieving the levelness adjustment of the upper surface of the evaporation tank.

[0029] Furthermore, for ease of processing and arrangement, it is preferable that the adjustment pad 20 is a rectangular block structure, in which case its horizontal projection is rectangular.

[0030] Furthermore, an integral adjusting pad 20 can be installed below each white cotton layer 10, or as follows: Figure 3 As shown, the integral adjusting pad 20 is disassembled into multiple adjusting pads 20 spliced ​​together. These multiple adjusting pads 20 can be arranged in one row or multiple rows. By adjusting the adjusting pads 20 at different positions individually, the height of the graphite electrode in the corresponding part can be adjusted specifically, meaning adjustments are made only where needed. This allows for corresponding adjustments to the crucible and other components on the top surface of the evaporation tank above that part. Therefore, this method achieves more precise adjustments. However, to prevent adjacent adjusting pads 20 from rubbing against each other and causing interference, a small gap should be left between the sides of adjacent adjusting pads 20 to ensure adjustment accuracy.

[0031] Furthermore, to ensure long-term durability, the material of the adjusting bolt 40 should be selected from the following: high-temperature bolt steel, high-temperature alloy steel, or heat-resistant steel.

[0032] Furthermore, to maintain the flatness of the upper surface of the adjusting shim 20 and prevent impurities from falling into the screw hole 21 and affecting subsequent use, it is preferable that the screw hole 21 is a blind hole, meaning it only penetrates the lower surface and not the upper surface. In this case, it should be ensured that the screw hole 21 has sufficient depth to prevent the adjusting bolt 40 from accidentally screwing into the root of the screw hole 21 and causing thread damage.

[0033] Furthermore, bolt heads come in various forms, but in order to ensure good contact with the upper surface of the evaporation tank bottom 30, flat-head bolts are preferred, meaning that in the adjusting bolt 40, the side of the nut away from the threaded end should be flat.

[0034] Further, the most common application occasion of the adjustment mode is initial setting of the evaporation equipment and replacement of the graphite electrode and other components, at this time, the adjustment pad 20 is adjusted to the predetermined height, and then each layer of components thereon is placed in turn, and then is placed into the predetermined position on the evaporation tank bottom 30, at this time, the adjusting bolt 40 can adopt various nut forms, such as flat head slotted bolt, internal hex bolt, hex head bolt and the like; however, sometimes, adjustment is also needed during equipment use, at this time, the adjusting bolt 40 is blocked by the evaporation tank bottom 30 directly below, and cannot be used with internal hex, socket and other wrenches, however, the evaporation tank bottom 30 at the position on the side of the adjusting bolt 40 is provided with a usable bottom opening, therefore, the open-end wrench or open-end wrench can be inserted from the side to adjust the adjusting bolt 40, for this purpose, the hex head bolt is preferably adopted.

[0035] Further, preferably, in the technical solution, the evaporation tank is also divided into multiple independent temperature zones, each temperature zone adopts an independent heating (graphite electrode) and cooling temperature control system, for example, is provided with two temperature zones (high temperature zone and low temperature zone), when preparing the composite current collector, in addition to placing the conventional aluminum or copper metal film material in the high temperature zone, low melting point metal film material can also be added in the low temperature zone, so that the film materials with different melting points can be evaporated at a specific temperature, and the evaporation quality is ensured. At this time, in order to avoid mutual interference, each temperature zone does not contact each other, and the corresponding white cotton layer 10 is arranged below each graphite electrode of each temperature zone, therefore, multiple white cotton layers 10 are also arranged at intervals (referring to Figure 1 The adjusting pad 20 below each white cotton layer 10 does not contact other white cotton layers 10.

[0036] Further, the screw hole 21 and the screwing length range of the adjusting bolt 40 are 0.5mm-15mm, that is, the adjustment range of the adjusting pad 20 is 0.5mm-15mm.
