Description

Technical Field

[0001] The utility model relates to the technical field of feeding devices, in particular to a feeding device for a coating machine. Background Art

[0002] A coating machine is a device that can evenly coat slurry made of different raw materials on the surface of various substrates according to different process thicknesses, and then wind it up after drying.

[0003] However, the coating machines currently on the market still have certain shortcomings in the practical process of loading components. For example, the current traditional feeding method is to manually pour the slurry into the material tank using a beaker, or to directly input it into the material tank using a pipe. After the slurry falls into the material tank, the slurry liquid level inside the material tank is highly unstable, or the slurry liquid shakes due to the impact of adding materials, resulting in poor thickness consistency of the equipment coating.

[0022] The present invention will be further described in detail below in conjunction with the embodiments. The following embodiments are intended to explain the present invention but the present invention is not limited to the following embodiments.

[0023] A coating machine feeding device, reference Figure 1-Figure 5 The device is installed above the coating machine trough, including a hopper 1, a discharge pipe, a control ball valve 203 and a discharge port 4.

[0024] The discharge port 4 is located below the hopper 1, and the bottom of the hopper 1 has an outlet 102 connected to the inlet end 201 of the discharge pipe. The discharge pipe is equipped with a control ball valve 203, and the outlet end 202 of the discharge pipe is connected to the discharge port 4;

[0025] There are more than two discharge pipes, which are arranged and installed at the bottom of the hopper, and each discharge pipe is equipped with a control ball valve.

[0026] Figure 1 As shown: the implementation of this solution requires that the coating machine feeding device be placed above the coating machine, which can simultaneously realize the caching and buffering of lithium battery slurry. When in use, it is only necessary to pour the slurry into the hopper 1, and adjust the descent speed of the slurry by controlling the ball valve to ensure that the slurry flows into the discharge port 4 at the bottom at a uniform speed, so as to achieve the problem of stabilizing the slurry liquid level and liquid shaking.

[0027] It should be noted that the control ball valve and the discharge pipe can be an integrated structure control ball valve 2, or a purchased control ball valve connected to the discharge pipe.

[0028] The outlet 102 at the bottom of the hopper 1 is a through threaded hole, the purpose of which is to be connected to one end of the control ball valve or one end of the discharge pipe, so that the slurry can flow out smoothly through the control ball valve.

[0029] Control ball valve, such as Figure 3 As shown, it can be rotated clockwise or counterclockwise to control the speed of slurry flow, thereby achieving the purpose of controlling the slurry flow rate. Components 201 and 202 are both designed with external threads, which are convenient for quick installation in conjunction with threaded holes.

[0030] The preferred discharge port structure is: the discharge port 4 is a long strip funnel shape, and the bottom of the discharge port 4 includes a narrow outlet 402. The length of the discharge port 4 must match the overall length of all discharge pipes arranged and installed at the bottom of the hopper to ensure that the outlets of all discharge pipes are located above the discharge port.

[0031] The discharge port is designed as a long strip with a small outlet gap, which allows the slurry to flow down at the same time in the discharge port area, ensuring that the liquid levels on the left and right sides of the slurry flowing into the material tank of the coating machine are stable and consistent.

[0032] like Figure 5 In order to fix the position of the discharge port and the discharge pipe, a connection block 3 is further provided to connect and fix the discharge port and the discharge pipe. More specifically, the connection block 3 is provided with a first threaded hole 301 and a discharge pipe connection hole 302; matching therewith, a threaded hole 401 is provided on the upper part or top of the discharge port, and the connection block 3 is installed above the discharge port 4 through the threaded hole 301, the threaded hole 401 and the screw.

[0033] As a preferred embodiment, the discharge pipe connection hole on the connection block is implemented as a second threaded hole, and the lower part of the discharge pipe is provided with a thread matching the second threaded hole, so that better fixation can be achieved.

[0034] As a preferred embodiment, threaded holes are provided on both sides of the discharge port, and the connecting block is provided with four first threaded holes, two of which are in a group, one group is installed on one side of the discharge port, and the other group is installed on the other side of the discharge port, and the discharge pipe connecting hole is located in the middle of the four first threaded holes.

[0035] At the same time, the connecting block, control ball valve, discharge pipe, discharge port and other components can be disassembled and cleaned to facilitate machine maintenance.

[0036] As a preferred embodiment, there are four discharge pipes, each of which is equipped with a control ball valve, or four integrated control ball valves 2 are included.

[0037] Considering the cost and design difficulty, preferably, the control ball valve is implemented as a manual control ball valve. The manual ball valve has lower cost and does not require other additional structures for communication, which is convenient.

[0038] In addition, it should be noted that the shapes and names of the parts and components of the specific embodiments described in this specification may be different. All equivalent or simple changes made based on the structure, features and principles described in the concept of the utility model patent are included in the protection scope of the utility model patent. The technicians in the technical field of the utility model can make various modifications or supplements to the specific embodiments described or replace them in a similar way, as long as they do not deviate from the structure of the utility model or exceed the scope defined by the claims, they should all fall within the protection scope of the utility model.
