Detailed Description

[0016] To enable those skilled in the art to better understand this utility model, the technical solution of this utility model will be further described below in conjunction with the accompanying drawings and embodiments.

In the description of this utility model, it should be understood that if terms such as "upper," "lower," "left," "right," "inner," and "outer" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, they are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, the terms used to describe positional relationships in the drawings are only for illustrative purposes and should not be construed as limiting this patent. For those skilled in the art, the specific meaning of the above terms can be understood according to the specific circumstances.

[0019] In the description of this utility model, unless otherwise explicitly specified and limited, the term "connection" or similar designation indicating the connection relationship between components should be interpreted broadly. For example, it can refer to a fixed connection, a detachable connection, or an integral part; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0020] Example 1: like Figure 1-3 As shown, this utility model provides a coating machine for a roller cutter, including a housing 1, a pump body 4, and a mixing tank 2 installed at the bottom of the housing 1. The output end and input end of the pump body 4 are connected to the top of the housing 1 and one side of the mixing tank 2 respectively through an output pipe 401 and an input pipe 402. It also includes a diverter pipe 403, and a third nozzle 404 is connected to the end of the diverter pipe 403. The nozzle of the third nozzle 404 is angled upward at 45°, which can spray the bottom of the roller cutter and dead corners to avoid incomplete coating.

[0021] In this embodiment, the shunt tube 403 is connected to the output tube 401 and is symmetrically distributed about the output tube 401.

[0022] In this embodiment, a grid plate 3 is installed above the mixing tank 2, and an L-shaped support frame 301 is installed on the upper surface of the grid plate 3. The upper part of the L-shaped support frame 301 is snapped to the end of the diversion pipe 403. Excess coating solution after spraying can re-enter the mixing tank 2 through the grid plate 3, and be recycled after filtration, thus saving resources.

[0023] In this embodiment, a guide rod 101 is installed near the top inner side of the housing 1, and a lead screw 6 is installed below the guide rod 101. One end of the lead screw 6 passes through the housing 1 and is connected to a first motor 601. A slider 602 is sleeved on the lead screw 6, and a hollow block 5 is fixedly connected to one side of the slider 602. When the first motor 601 is started, the lead screw 6 is driven to rotate, which can drive the slider 602 and the hollow block 5 to move laterally along the guide rod 101, so that the coating is more comprehensive and uniform.

[0024] In this embodiment, a first nozzle 501 is vertically installed at the bottom center of the hollow block 5, and a second nozzle 502 is installed at both ends of the bottom at an angle. The hollow block 5 is convex in shape, and the top is connected to the output pipe 401 to achieve spraying in multiple directions and avoid uneven coating.

[0025] In this embodiment, a first column 302 and a second column 303 are respectively installed at both ends of the grid plate 3. A turntable 8 is installed on the side of the first column 302 and the second column 303 near the center. The turntable 8 is used to install a roller cutter.

[0026] In this embodiment, a cylinder 10 is installed on the side of the first column 302 near the housing 1. The cylinder 10 pushes the turntable 8 to move laterally, which, together with the fixed turntable 8 on the side of the second column 303, clamps the cutter and prevents the cutter from sliding.

[0027] In this embodiment, a second motor 9 is installed on the side of the second column 303 near the housing 1. The second motor 9 is started to drive the turntable 8 and the roller cutter to rotate synchronously. During the rotation of the roller cutter, each nozzle continuously sprays coating to ensure that each tooth surface and tooth groove can be evenly covered with coating.

[0028] In this embodiment, the mixing tank 2 includes a rotating rod 201 fixed to the bottom of the mixing tank 2. A third motor 205 is installed at one end of the rotating rod 201 that protrudes from the bottom of the tank body 1. When the third motor 205 is started, it drives the rotating rod 201 and the stirring rod 202 to rotate synchronously, so as to fully stir the coating solution in the tank and avoid the solution from settling.

[0029] In this embodiment, stirring rods 202 and U-shaped frames 203 are symmetrically installed on both sides of the rotating rod 201. A first filter screen 204 is installed inside the U-shaped frame 203. During the stirring process, the coating solution flows through the first filter screen 204 of the U-shaped frame 203 for filtration, so that large particles of impurities are intercepted on the filter screen to avoid affecting the coating effect.

[0030] In this embodiment, the top of the mixing tank 2 is open and a second filter screen 206 is installed. An inclined guide plate 7 is installed between the mixing tank 2 and the grid plate 3. The second filter screen 206 can intercept impurities mixed in during the spraying process to avoid contaminating the solution in the mixing tank 2; the guide plate 7 can guide the solution.

[0031] The working principle of this utility model is as follows: First, the second motor 9 is started, causing the turntable 8 to drive the roller cutter to rotate synchronously. Then, the third motor 205 is started, causing the rotating rod 201 and the stirring rod 202 to rotate synchronously, so as to fully stir the coating solution in the mixing tank 2 and avoid solution sedimentation, which would affect the coating effect. After that, the pump body 4 is started, and the filtered coating solution is drawn out through the input pipe 402 and then transported to the hollow block 5 and the diversion pipe 403 through the output pipe 401. The solution is then sprayed onto the roller cutter from the first nozzle 501, the second nozzle 502 and the third nozzle 404, respectively. During this process, the first motor 601 is started to drive the lead screw 6 to rotate, which drives the slider 602 and the hollow block 5 to move laterally along the guide rod 101. This allows the first nozzle 501 to spray the top of the roller cutter teeth vertically, and the second nozzle 502 to spray the sides of the tooth surface at an angle. With the third nozzle 404, which is angled upward at 45°, the top, sides and bottom of the roller cutter are fully covered. Since the roller cutter is rotating, it can be ensured that each tooth surface and groove is evenly covered with coating.

[0032] The design of the first nozzle 501 and the second nozzle 502, together with the third nozzle which is angled upward at 45°, can achieve full coverage of the top, sides and bottom of the roller cutter, ensuring that each tooth surface and groove of the roller cutter is evenly covered with coating.
