Referring to fig. 1 to 4, a spraying apparatus 1000 for spraying a battery film according to an embodiment of the present utility model includes a housing 100, an atomizing turntable 200, a feed pipe 300, and a leveling mechanism 400. The housing 100 is formed with a spraying port 110; the atomizing turntable 200 is disposed in the housing 100 and corresponds to the spraying port 110; the feed pipe 300 is provided with a discharge port 310, and the discharge port 310 is used for supplying spraying agent to the atomizing turntable 200; the leveling mechanism 400 is mounted on the housing 100 and connected to the feeding pipe 300 for leveling the feeding pipe 300.

In the spraying apparatus 1000 according to the embodiment of the present utility model, the feed pipe 300 is connected to the leveling mechanism 400 mounted on the housing 100, and the feed pipe 300 is adjusted to be in a horizontal state by the leveling mechanism 400, so that the feed liquid is uniformly distributed in the feed pipe 300, so that the flow rate of the feed liquid supplied from the discharge port 310 to each atomizing turntable 200 is uniform, and the flow rate of the feed liquid sprayed from the spraying port 110 is uniform, so as to ensure uniform film thickness of the battery film.

In particular, the housing 100 may be a structural member for housing the atomizing turntable 200, the feed tube 300, and the leveling mechanism 400. Further, the housing 100 may have a cavity in which the atomizing turntable 200, the feed tube 300, and the leveling mechanism 400 may all be housed. The shape of the case 100 may be a rectangular parallelepiped, a square, a cylinder, or the like, and the embodiment of the present utility model is not particularly limited to the shape of the case 100.

The spraying port 110 may be an opening for spraying the atomized feed liquid out of the housing 100, and the spraying port 110 may be formed at any position on the housing 100. Alternatively, the spray orifice 110 may be positioned such that the atomized feed liquid achieves a maximum spray area. The size of the spray orifice 110 may be set according to the path of the atomized feed.

The atomizing disk 200 may be a structural member for atomizing the feed liquid from the discharge port 310. The atomizing disk 200 may be plural, for example, the atomizing disk 200 may be five, six, seven or more, and the embodiment of the present utility model is not particularly limited to the number of atomizing disks 200. The atomizing turntables 200 may be disposed in the housing 100 at intervals, and the pattern layout of the atomizing turntables 200 may be set according to the requirements. Taking the case 100 as a cuboid as an example, the plurality of atomizing turntables 200 may be arranged along the height direction of the cuboid, and the path of atomized feed liquid ejected from the spraying device 1000 is perpendicular to a certain side surface of the height direction. At this time, the spraying port 110 may be formed on this side, and a plurality of atomizing disks 200 may correspond to the spraying port 110.

The feeding pipe 300 may be a circular pipe, a square pipe, etc., and embodiments of the present utility model are not limited to the specific shape of the feeding pipe 300. The feed liquid in the spray apparatus 1000 is typically corrosive and thus the feed tube 300 may be made of a material that is resistant to corrosion. The liquid pressure in the feed tube 300 is greater than at the discharge port 310 and the feed liquid in the feed tube 300 can flow to the discharge port 310. Taking the feeding tube 300 as a circular tube as an example, the discharge port 310 may be disposed at an outer circumferential surface of the feeding tube 300. The number of the discharge ports 310 may be plural, and the plurality of discharge ports 310 may be disposed on the outer circumferential surface of the feeding tube 300 at intervals, and the number of the discharge ports 310 may be determined according to the number of the atomizing turntables 200.

The leveling mechanism 400 may be mounted to the housing 100 by bolting, threading 4310, etc. and connected to the feed tube 300. For example, the leveling mechanism 400 may include a first bolt hole, the housing 100 may include a second bolt hole, and the leveling mechanism 400 and the housing 100 may be connected through the first bolt hole, the second bolt hole, and one bolt. Similarly, the leveling mechanism 400 may include a third bolt hole, the feeding pipe 300 may include a fourth bolt hole, and the leveling mechanism 400 and the feeding pipe 300 may be connected through the third bolt hole, the fourth bolt hole and one bolt.

The leveling mechanism 400 may include a plurality of structural members that may be mounted to the ends of the material pipe by threaded connections, bolting, or the like. The feed tube 300 may be adjusted to the horizontal by connecting a connection member such as a bolt or screw between the structural member and the feed tube 300 to adjust the inclination of the feed tube 300.

Of course, the leveling mechanism 400 may also adjust the feeding tube 300 to a horizontal state in other manners, which is not limited in the embodiment of the present utility model.

Referring to fig. 3, in some embodiments, the leveling mechanism 400 includes a first mounting member 410, a second mounting member 420, and an adjusting member 430, wherein the first mounting member 410 is fixedly connected to the housing 100, the second mounting member 420 is fixedly connected to the feeding tube 300, and the adjusting member 430 is connected to the first mounting member 410 and the second mounting member 420 for driving the second mounting member 420 to move relative to the first mounting member 410.

As such, the housing 100 is typically fixed to the machine tool, and thus the housing 100 can be considered a reference. While the first mount 410 and the second mount 420 are fixedly connected to the housing 100 and the feed tube 300, respectively, the first mount 410 may be regarded as a reference. Thus, the adjustment member 430 drives the second mounting member 420 to move relative to the first mounting member 410, which corresponds to adjusting the inclination of the feeding tube 300, thereby achieving the adjustment of the level of the feeding tube 300.

Specifically, the first mount 410 may be a plate fixed to the housing 100. Similarly, the second mount 420 may be a plate secured to the housing 100. The first mounting member 410 may be fixedly connected to the housing 100 by welding, bolting, etc., which is not limited in the embodiment of the present utility model. Similarly, the second mounting member 420 may be fixedly coupled to the feeding tube 300 by welding, bolting, etc., which is not limited in the present embodiment.

The adjustment member 430 may drive the second mount member 420 toward or away from the first mount member 410, and the adjustment member 430 may cause the second mount member 420 to move toward or away from the first mount member 410 by exerting pressure on the second mount member 420. The adjusting member 430 may also drive the second mounting member 420 toward or away from the first mounting member 410 in other manners, which are not limited in this embodiment of the present utility model.

Referring to fig. 3 and 5, in some embodiments, the adjusting member 430 includes a screw 431, the screw 431 is provided with threads 4310, the first mounting member 410 and/or the second mounting member 420 is provided with a screw hole 401, and the screw 431 is screwed into the screw hole 401.

In this way, the adjusting member 430 may adjust the distance between the first and second mounting

members

410 and 420 by adjusting the distance by which the screw 431 is screwed into the screw hole 401, and thus may adjust the inclination of the feeding pipe 300. It will be appreciated that when the screws 431, the first mounting member 410 and the second mounting member 420 are disposed at both ends of the feeding tube 300 and the housing 100, the inclination of the feeding tube 300 may be changed by adjusting the distance by which the screws 431 at both ends are screwed into the screw holes 401 at the corresponding sides, and finally the feeding tube 300 may be horizontal by adjusting multiple times.

Specifically, screw 431 may be any commercially available type of screw 431, or may be a custom made screw 431. The length of threads 4310 may be greater than the distance between first mount 410 and second mount 420 at any time to ensure that the connection of screw 431 to threads 4310 does not fail. The screw hole 401 may be a through hole penetrating the first and second mounting

members

410 and 420, and the shape of the screw hole 401 may be circular, square, etc., which is not limited in the embodiment of the present utility model.

Referring to fig. 2 and 3, in some embodiments, a second mount 420 is secured to the end 311 of the feed tube 300.

Thus, the second mounting member 420 is convenient to mount and low in maintenance cost. Meanwhile, since the discharge port 310 is generally formed on the outer circumferential surface of the feeding tube 300, the second mounting member 420 is fixed to the end 311 of the feeding tube 300 so as not to block the discharge port 310.

Specifically, the second mounting member 420 may be closely attached to the end 311 of the feeding tube 300, or may be spaced from the end 311 of the feeding tube 300, which is not limited in the embodiment of the present utility model, and only the second mounting member 420 is not displaced relative to the feeding tube 300.

Referring to fig. 3, in some embodiments, the leveling mechanism 400 further includes an elastic member 440, the elastic member 440 connecting the first mounting member 410 and the second mounting member 420.

In this way, the elastic member 440 may apply a pre-tightening force between the first mounting member 410 and the second mounting member 420, preventing slippage when the first mounting member 410 starts to be displaced from the second mounting member 420, so as to improve the reliability of the leveling mechanism 400.

Specifically, the elastic member 440 may be a leaf spring, a coil spring, a torsion bar spring, a gas spring, or the like. The elastic member 440 may be attached to any position of the first mounting member 410 and the second mounting member 420 without interfering with other parts of the leveling mechanism 400.

Referring to fig. 3, in some embodiments, the number of leveling mechanisms 400 is two, and two leveling mechanisms 400 are disposed on two sides of the center of the feeding tube 300 along the axial direction of the feeding tube 300.

In this manner, the inclination of the feed tube 300 may be adjusted by adjusting the leveling mechanisms 400 on both sides of the feed tube 300, which may increase the efficiency of the leveling mechanisms 400 and may allow the feed tube 300 to be adjusted to level faster than one leveling mechanism 400.

Specifically, taking the feeding pipe 300 as a circular pipe as an example, the axial direction of the feeding pipe 300 may be the direction in which the connecting lines of the centers of the two end surfaces of the circular pipe are located. The distance between the two leveling mechanisms 400 may be less than, equal to, or greater than the length of the feed tube 300. The two leveling mechanisms 400 may or may not be symmetrical about the feeding tube 300, and the embodiment of the present utility model is not limited thereto.

Referring to fig. 3, in some embodiments, two leveling mechanisms 400 are respectively connected to two axial ends of the feeding tube 300.

Thus, compared with other positions, the two leveling mechanisms 400 are respectively connected at two axial ends of the feeding pipe 300, so that maintenance is facilitated, and the leveling mechanisms 400 can be prevented from shielding the discharge hole 310 of the feeding pipe 300.

Specifically, taking the example that the feeding tube 300 is a circular tube, the "two ends of the feeding tube 300 in the axial direction" refers to regions near the two end faces of the circular tube.

Referring to fig. 2, 6 and 7, in some embodiments, the feeding pipe 300 is provided with a feeding port 320, and the feeding port 320 is disposed at a middle position in an axial direction of the feeding pipe 300.

In this way, the feed liquid entering the feed pipe 300 from the feed inlet 320 can be uniformly distributed in the feed pipe 300, and the pressure of the feed pipe 300 is uniform throughout, so that the flow rate of the liquid flowing out of the discharge outlet 310 is uniform.

Specifically, the inlet 320 may be an opening penetrating a peripheral surface of one side of the feeding pipe 300. Taking the example that the feeding pipe 300 is a circular pipe, the feeding port 320 may be disposed at a center of a line connecting two end circles of the circular pipe. Alternatively, the inlet 320 may protrude from the outer circumferential surface of the feeding tube 300. The feeding port 320 may be integrally formed with the feeding pipe 300, or may be formed separately from the feeding pipe 300, and then assembled together by welding or interference connection, which is not limited in the embodiment of the present utility model.

Referring to fig. 2 and 8, in some embodiments, the number of the discharge ports 310 is plural, the discharge ports 310 are in one-to-one correspondence with the atomizing turnplate 200, and each discharge port 310 is connected with a discharge pipe 500, and the discharge pipe 500 extends toward the atomizing turnplate 200.

Thus, the discharge ports 310 are arranged in one-to-one correspondence with the atomizing turnplate 200, so that the efficiency of the feed liquid entering the atomizing turnplate 200 is high, and the discharge pipes 500 cannot be mutually wound, so that the maintenance is convenient.

Specifically, the number of the discharge ports 310 may be five, six, seven or more, and embodiments of the present utility model are not particularly limited to the number of the discharge ports 310. The material liquid flowing out from the discharge port 310 can flow into the atomizing turntable 200 through the discharge pipe 500, and the material, shape and length of the discharge pipe 500 are not limited. Alternatively, the discharge pipe 500 may be a circular hose of polyester polyurethane to obtain good chemical resistance and corrosion resistance, and the length of the discharge pipe 500 may be set according to the distance between the corresponding discharge port 310 and the atomizing turntable 200.

Referring to FIGS. 2 and 8, in some embodiments, a throttle 600 is provided on the tapping pipe 500.

In this manner, the flow of feed liquid in the discharge pipe 500 may be controlled, and the restrictor 600 may maintain a consistent flow of feed liquid out of each discharge pipe 500 when the liquid distribution within the feed pipe 300 is uneven and results in inconsistent flow of feed liquid out of each discharge port 310.

In particular, the restrictor 600 may be selected from commercially available or custom made, and embodiments of the present utility model are not limited in this regard.
