[0030] The technical solution of the utility model will be clearly and completely described below in conjunction with the embodiments. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0031] like Figures 1 to 4 As shown, an embodiment of the utility model provides a miniaturized feeding device for a coating system, the coating system includes a coating die head, and the miniaturized feeding device includes: a feeding tank 1, a filtering component 2, an iron removal component 3, a power component 4 and a frame 5; a feeding port 11 and a discharging port 12 are provided on the feeding tank 1, and the feeding tank 1 is arranged on the frame 5; the discharging port 12 is connected to the coating die head through the filtering component 2, the iron removal component 3 and the power component 4, the iron removal component 3 and the power component 4 are arranged below the feeding tank 1, and the filtering component 2 is arranged beside the feeding tank 1.

[0032] The miniaturized feeding device provided in this embodiment is used for a coating system, and the coating device includes a coating die head, and the coating system coats the surface of the substrate through the coating die head. The miniaturized feeding device in this embodiment is used to convey coating slurry to the coating die head. The feeding device includes a feeding tank 1, a filtering component 2, an iron removal component 3, a power component 4 and a frame 5. The frame 5 is a frame-type structure, and the feeding tank 1 is arranged in the frame 5 through a connecting ear arranged on the side wall. The feeding tank 1 has a feed inlet 11 and a discharge port 12, and the feed inlet 11 of the feeding tank 1 is connected to the coating slurry source, and the filter component 2, the power component 4 and the iron removal component 3 are arranged at the discharge port 12 of the feeding tank 1, and the discharge end of the feeding tank 1 is connected to the coating die head through the filtering component 2, the power component 4 and the iron removal component 3 to convey the coating slurry to the coating die head. The filter assembly 2 can filter out large particles in the coating slurry, such as agglomerates, and the iron removal assembly 3 is used to remove magnetic substances in the coating slurry. The filter assembly 2 cooperates with the iron removal assembly 3 to protect the coating die head and improve the coating quality of the coating die head. The power assembly 4 is used to provide power for the flow of the coating slurry. In order to realize the miniaturization of the feeding device, the frame 5 suspends the feeding tank 1, the iron removal assembly 3 and the power assembly 4 are both arranged below the feeding tank 1, and the filter assembly 2 is arranged beside the feeding tank 1.

[0033] In this embodiment, the feed tank 1 is suspended by setting up a frame 5, so that the power component 4 and the iron removal component 3 can be set below the feed tank 1, and the filter component 2 is set on the side of the feed tank 1. Compared with the prior art, the various structural layouts of the miniaturized feeding device of this embodiment are reasonable, which can effectively reduce the space occupancy rate and facilitate layout.

[0034] Preferably, in the present embodiment, the discharge port 12 is disposed on the bottom wall of the supply tank 1 , so as to facilitate the connection between the discharge port 12 and the power assembly 4 and the iron removal assembly 3 .

[0035] The miniaturized feeding device provided by the embodiment of the utility model is as follows: Figures 1 to 4 As shown, the power assembly 4, the iron removal assembly 3 and the filter assembly 2 are connected to the discharge port 12 in sequence.

[0036] The above content mentioned that the power component 4 is used to provide power for the flow of the coating slurry. The power component 4 is preferably a screw pump, which can also stir the coating slurry during the process of conveying the coating slurry to avoid precipitation in the coating slurry and improve the uniformity of the coating slurry. Of course, the power component 4 can also be a plunger pump, etc. During the process of conveying the coating slurry by the power component 4, and when the coating slurry is buffered and stirred in the feed tank 1, metal debris may fall into the coating slurry. Therefore, the iron removal component 3 is arranged downstream of the power component 4 and upstream of the filter component 2, so as to remove the magnetic material in the coating slurry, avoid affecting the operation of the filter component 2 and avoid affecting the coating quality. After the filter component 2 filters out the large particles in the coating slurry, the coating slurry is conveyed to the coating die head. That is, after the coating slurry is discharged from the feed tank 1 through the discharge port 12, it is conveyed to the coating die head after passing through the power component 4, the iron removal component 3 and the filter component 2 in sequence.

[0037] The miniaturized feeding device provided by the embodiment of the utility model is as follows: Figures 1 to 4 As shown, the filter assembly 2 is a tubular structure, and the filter assembly 2 is vertically arranged beside the supply tank 1.

[0038] In this embodiment, the filter assembly 2 includes a filter, which is a tubular structure, specifically including a tubular shell and a filter screen arranged in the shell. After the slurry enters the shell of the filter, it is filtered out by the filter screen to remove large particles and then discharged. Therefore, the filter is arranged vertically beside the feed tank 1, so that the layout of the miniaturized feed device is more reasonable, the occupied space is reduced, and the layout of the feed device is convenient.

[0039] The miniaturized feeding device provided by the embodiment of the utility model is as follows: Figures 1 to 4 As shown, the iron removal assembly 3 is arranged above the power assembly 4, and a connecting piece 71 is provided at one end of the iron removal assembly 3 communicating with the filter assembly 2, and the connecting piece 71 is connected to the frame 5.

[0040] In this embodiment, the iron removal component 3 includes an iron remover, which is a tubular structure, specifically including a tubular shell and a magnet rod disposed in the shell. The slurry enters the iron remover from one end of the iron remover shell and is discharged from the other end of the iron remover shell. When the slurry flows in the shell of the iron remover, the magnet rod can absorb magnetic substances such as iron impurities in the slurry. The power component 4 is a screw pump, which also has a tubular structure; the iron removal component 3 and the power component 4 are both fed at one end and discharged at the other end. Therefore, the iron removal component 3 is arranged above the power component 4, and the feed end of the power component 4 is located on the same side as the discharge end of the iron removal component 3, and the feed end of the power component 4 is located on the same side as the discharge end of the iron removal component 3.

[0041] In this embodiment, since the power component 4 is arranged below the iron removal component 3, the power component 4 can be connected to the frame 5 or directly connected to the ground, but the iron removal component 3 is suspended in the air, one end of which can be supported by the power component 4, but the other end also needs to support the filter component 2, and the strength requirement is relatively high. For this reason, a connecting member 71 is provided at the end of the iron removal component 3 that is connected to the filter component 2, and the connecting member 71 can be connected to the frame 5.

[0042] It is understandable that, in this embodiment, the iron removal assembly 3 and the power assembly 4 can also be arranged side by side below the feed tank 1, which also solves the problem of the feed system occupying too much space in the prior art.

[0043] Optionally, in this embodiment, the connecting member 71 may be a connecting plate, which connects the iron removal assembly 3 and the frame 5 by bolt connection or welding, and the connecting member 71 may also be a structure such as a hoop or a clamp, which can also achieve the purpose of connecting the iron removal assembly 3 and the frame 5. By providing the connecting member 71, the strength of the iron removal assembly 3 can be ensured, and the iron removal assembly 3 can be prevented from being damaged due to excessive load.

[0044] The miniaturized feeding device provided by the embodiment of the utility model is as follows: Figures 1 to 4 As shown, it also includes a feeding trolley 6, and the frame 5 is arranged on the feeding trolley 6.

Through the feeding trolley 6, the above-mentioned feeding tank 1, power assembly 4, iron removal assembly 3 and filter assembly 2 can be driven to move, so as to better adapt to the workplace.

[0046] Optionally, in this embodiment, the miniaturized feeding device also includes an electrical control box 9 for controlling its operating state. Accordingly, the electrical control box 9 is also arranged on the feeding trolley 6 , and the electrical control box 9 and the filter assembly 2 are located on opposite sides of the frame 5 .

[0047] In this embodiment, the feeding trolley 6 includes a support plate 61, one side of the support plate 61 is used to accommodate structures such as the electric control box 9 and the frame 5, and the other side is provided with a wheel 62, and the wheel 62 is provided with a brake assembly for controlling the rotation of the wheel 62 to improve safety. Further, the side of the support plate 61 provided with the wheel 62 is provided with a support foot, and the support foot is used to support the support plate 61 when the miniaturized feeding device is running, so as to prevent the wheel 62 from being damaged due to excessive load.

The power assembly 4 is arranged on the support structure 72 to ensure that the device can operate stably.

[0050] The miniaturized feeding device provided by the embodiment of the utility model is as follows: Figures 1 to 4 As shown, the iron removal assembly 3 and the power assembly 4 both extend along the length direction of the feeding trolley 6 .

[0051] The above content mentioned that the iron removal component 3 and the power component 4 are also tubular structures, and the support plate 61 of the feeding trolley 6 is a rectangular structure. In order to facilitate the arrangement of subsequent structures, the iron removal component 3 and the power component 4 are extended along the length direction of the feeding trolley 6; accordingly, the feeding tank 1 and the filtering component 2 are also spaced apart along the length direction of the feeding trolley 6.

[0052] The miniaturized feeding device provided by the embodiment of the utility model is as follows: Figures 1 to 4 As shown, the coating system is a double-sided coating system, and the double-sided coating system includes two coating dies; the discharge port 12 is connected to the two coating dies; the power assembly 4, the iron removal assembly 3 and the filter assembly 2 are each arranged in two groups, the two groups of the power assembly 4 are arranged in parallel, the two groups of the iron removal assembly 3 are arranged in parallel, and the two groups of the filter assembly 2 are arranged in parallel.

[0053] Preferably, in this embodiment, the coating system is a double-sided coating system, which can coat both the front and back sides of the substrate at the same time, thereby improving production efficiency. Accordingly, the double-sided coating system includes two coating dies, and the two coatings coat the front and back sides of the substrate respectively. In this embodiment, the miniaturized feeding device can feed the two coating dies at the same time.

[0054] Specifically, in the present embodiment, the two coating die heads are both connected to the discharge port 12, and correspondingly, the power assembly 4, the iron removal assembly 3 and the filter assembly 2 are also provided in two groups, so that the power assembly 4, the iron removal assembly 3 and the filter assembly 2 are provided between each coating die head and the discharge port 12. As mentioned above, the power assembly 4 and the iron removal assembly 3 are both arranged along the length direction of the feeding trolley 6. Therefore, when the miniaturized feeding device is provided with two groups of power assemblies 4 and iron removal assemblies 3, the two groups of power assemblies 4 are arranged in parallel, and the two groups of iron removal assemblies 3 are arranged in parallel, thereby realizing the design concept of miniaturization and facilitating the position selection of the miniaturized feeding device.

[0055] Optionally, in this embodiment, two discharge ports 12 may be provided, and the two discharge ports 12 correspond to two coating die heads respectively. Preferably, only one discharge port 12 is provided, thereby simplifying the structure of the miniaturized feeding device.

The above-mentioned feed pipeline 8 extends from the discharge port 12. The feed pipeline 8 is divided into two branches 82 at one end away from the discharge port 12 to connect with the two groups of power components 4.
