Abstract
Description
Technical Field
[0001] The utility model relates to tinplate production, and more specifically, to a primer dipping device for tinplate production. Background Art
[0002] In tinplate production, a substrate needs to be coated with a primer on the printing surface before entering a tinplate printing machine. The existing method is to pass the phosphated substrate through a coating machine, and the coating machine coats the primer on the printing surface by spraying or extrusion. On the one hand, the cost is relatively high. On the other hand, since the primer contains solids, the coating by spraying or extrusion may be blocked during production, resulting in uneven thickness of the primer coated on the printing surface of the substrate, and thus quality problems in the final tinplate product. Summary of the Utility Model
[0003] In view of the above problems, the utility model provides a primer dipping device for tinplate production, which has low production cost, stable primer dipping quality, and is beneficial to industrial production.

The conveying system includes a middle-position horizontally leftward moving conveying section, an obliquely downward moving conveying section, a low-position horizontally leftward moving conveying section, an obliquely upward moving conveying section, and a high-position horizontally rightward moving conveying section. The low-position horizontally leftward moving conveying section is located in the paint dipping tank. When the substrate moves through the low-position horizontally leftward moving conveying section, the lower surface of the substrate is below the liquid level of the paint dipping tank.
[0005] Optionally, a number of overflow holes are equidistantly opened on the tank wall of the paint dipping tank, and the bottom of the overflow holes is located between the lower surface and the upper surface of the substrate when the substrate moves through the low-position horizontally leftward moving conveying section.
[0006] Optionally, a buffer structure is installed at the bottom of the paint dipping tank. The buffer structure includes an outer tank, an inner tank located in the outer tank, and a cover plate.

The inner tank and the cover plate enclose an inner cavity, and the outer tank, the inner tank, and the cover plate enclose an outer cavity. An inlet hole through which a primer liquid inlet pipe passes is opened on the outer tank, and the inlet hole communicates with the outer cavity. A number of connecting holes are evenly opened on the tank wall of the inner tank to conduct the outer cavity and the inner cavity. A number of liquid distribution holes are equidistantly opened on the cover plate above the inner cavity.
[0007] Optionally, in the primer dipping production, the amount of primer liquid replenished into the paint dipping tank per unit time = the amount of primer liquid taken away by the substrate per unit time + the amount of primer liquid overflowing from a number of overflow holes per unit time.

Obviously, the described embodiments are some, but not all, of the embodiments of this application. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of this application without creative efforts shall fall within the scope of protection of this application.
[0026] Please refer to Figure 1 Figure 1 FIG. 1 is a schematic structural diagram of a primer dipping device for iron printing production provided by the present utility model.
[0027] A primer dipping device for iron printing production includes a paint dipping tank 1, a conveying system 3, and a substrate 4. The substrate 4 moves through the conveying system 3. The conveying system 3 includes a middle-position horizontal leftward moving conveying section 31, an obliquely downward moving conveying section 32, a low-position horizontal leftward moving conveying section 33, an obliquely upward moving conveying section 34, and a high-position horizontal rightward moving conveying section 35. The low-position horizontal leftward moving conveying section 33 is located inside the paint dipping tank 1. When the substrate 4 moves through the low-position horizontal leftward moving conveying section 33, the lower surface of the substrate 4 is below the liquid level of the paint dipping tank 1.
[0028] After the substrate 4 is dipped in paint, it passes through the drying device 2 through the high-position horizontal rightward moving conveying section 35.
[0029] Through the paint dipping tank 1, the middle-position horizontal leftward moving conveying section 31, the obliquely downward moving conveying section 32, the low-position horizontal leftward moving conveying section 33, the obliquely upward moving conveying section 34, and the high-position horizontal rightward moving conveying section 35, on the one hand, the substrate 4 is in contact with the paint dipping tank 1 through the low-position horizontal leftward moving conveying section 33, and the primer covers the printing surface, avoiding the problem of uneven thickness of the primer. The thickness of the primer on the printing surface can be controlled by the moving speed of the substrate 4 or / and the length of the horizontal leftward moving conveying section 71. On the other hand, this setting method makes the overall occupied area of the primer production line small.
[0030] The middle-position horizontal leftward moving conveying section 31 and the obliquely downward moving conveying section 32 are steered by a steering wheel, the obliquely downward moving conveying section 32 and the low-position horizontal leftward moving conveying section 33 are steered by a steering wheel, the low-position horizontal leftward moving conveying section 33 and the obliquely upward moving conveying section 34 are steered by a steering wheel, and the obliquely upward moving conveying section 34 and the high-position horizontal rightward moving conveying section 35 are steered by a steering wheel.
[0031] Those skilled in the art should be aware that the dipping tank 1 is installed on the ground, and the conveying system 3 is installed through support brackets. Regarding how to install the dipping tank 1 and the conveying system 3, as well as the power supply of the conveying system 3, and the tensioning and traction of the substrate 4 on the conveying system, those skilled in the art can set or select according to needs. This is the prior art and will not be specifically limited here.
[0032] In one or more specific embodiments of the present invention, in order to control the quality of primer dipping, please refer to Figure 1 and refer to Figure 2 , Figure 2 is a schematic diagram of the position of the substrate and the overflow holes during dipping of the present invention. A number of overflow holes 11 are equidistantly opened on the tank wall of the dipping tank 1. The bottom of the overflow hole 11 is located between the lower surface and the upper surface of the substrate 4 when the substrate 4 moves through the low-level horizontal leftward conveying section 33. At this time, the lower surface of the substrate 4 during dipping is below the dipping liquid level, and the upper surface is above the dipping liquid level, ensuring that only the printing plate surface is dipped with primer.
[0033] In one or more specific embodiments of the present invention, in order to control the gentle fluctuation of the liquid level of the dipping tank 1 and the paint liquid concentration in the dipping section, please refer to Figure 1 and refer to Figures 3 - 6 , Figure 3 is a schematic diagram of the outer tank of the buffer structure of the present invention, Figure 4 is a schematic diagram of the inner tank of the buffer structure of the present invention, Figure 5 is a schematic diagram of the cover plate of the buffer structure of the present invention, Figure 6 is a schematic diagram of the inner cavity and the outer cavity of the buffer structure of the present invention; a buffer structure 5 is installed at the bottom of the dipping tank 1. The buffer structure 5 includes an outer tank 51, an inner tank 52 located in the outer tank 51, and a cover plate 53. The top of the inner tank 52 is flush with the top of the outer tank 51. The cover plate 53 is fixed to the tops of the outer tank 51 and the inner tank 52. The inner tank 52 and the cover plate 53 enclose an inner cavity 54, and the outer tank 51, the inner tank 52, and the cover plate 53 enclose an outer cavity 55. An inlet hole 56 through which the primer liquid inlet pipe passes is opened on the outer tank 51, and the inlet hole 56 communicates with the outer cavity 55. A number of communication holes 57 are evenly opened on the tank wall of the inner tank 52, and the outer cavity 55 and the inner cavity 54 are conducted through the communication holes 57. A number of liquid distribution holes 58 are equidistantly opened on the cover plate 53 above the inner cavity 54. Through the settings of the outer cavity 55, the inner cavity 54, the communication holes 57, and the liquid distribution holes 58, the uniformly stirred primer liquid enters the outer cavity 55 after being pumped through a pipeline (not shown in the figure, and this pipeline passes through the tank wall of the dipping tank and the outer tank 51) and enters the inlet hole 56, then enters the inner cavity 54 through the communication holes 57, and then enters the cavity of the dipping tank 1 from the liquid distribution holes 58. The liquid slowly surges into the dipping tank 1 from the bottom through the liquid distribution holes 58, and the liquid level fluctuation of the dipping tank 1 is small. During installation, the outer wall of the outer tank 51 is fitted and installed with the inner wall of the dipping tank 1.
[0034] In one or more specific embodiments of the present utility model, in dip painting production, the amount of primer liquid replenished into the dip painting tank 1 per unit time = the amount of primer liquid carried away by the substrate per unit time + the amount of primer liquid overflowing from a number of overflow holes 11 per unit time.
[0035] Since the distance between the upper surface and the lower surface of some substrates 4 is relatively small, the bottom of the overflow holes 11 of the dip painting tank needs to be controlled more strictly. To solve this problem, please refer to Figure 7 , between adjacent two conveyor wheels of the low-position horizontally leftward moving conveyor section 33, baffles 6 are symmetrically arranged. The baffles 6 are located outside the part of the substrate 4 being dip painted. One side of the baffle 6 facing the substrate 4 being dip painted is in contact with the edge of the substrate 4 being dip painted, preventing the primer liquid from overflowing onto the upper surface of the substrate 4 being dip painted.
[0036] Those skilled in the art should be aware that the baffle 6 can be installed on the tank wall of the dip painting tank 1 through a support rod or the like, or can be installed in other ways, as long as it can play a blocking role and does not affect the low-position horizontally leftward moving conveyor section 33. It is not particularly limited here, and those skilled in the art can set or select according to needs.
[0037] To better achieve the blocking function, please refer to Figure 8 , in one or more specific embodiments of the present utility model, the contact surface 61 of the baffle 6 in contact with the edge of the substrate 4 being dip painted is an elastic surface. The elastic surface can be formed by the baffle 6 using elastic rubber, or can be formed by covering a layer of elastic rubber at the position of the contact surface 61 of the baffle 6. It is not particularly limited here.
[0038] Finally, it should be noted that: the above embodiments are only used to illustrate the technical solutions of the present utility model, rather than to limit it; although the present utility model has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present utility model.
