[0003] This utility model discloses a blade sharpening device for a slicing machine, which aims to solve the technical problems in related technologies, such as the need to regularly disassemble and sharpen the blades, which is time-consuming, labor-intensive, and inconvenient to operate.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A sharpening device for a slicing machine includes a connecting frame with a movable groove inside. A lead screw is rotatably connected inside the movable groove. A fixed frame is fixedly installed on one side of the connecting frame, and a motor is fixedly installed on one side of the fixed frame. A movable block is threadedly connected to the outside of the lead screw and inside the movable groove. A fixed box is fixedly installed on one side of the movable block. The fixed box has symmetrically formed blade grooves on both sides. Sharpening wheels are symmetrically rotatably connected inside the fixed box. Spray pipes are symmetrically connected to one side of the fixed box through fixed pipes. The two adjacent sides of the fixed pipes are connected to an external connecting pipe through connectors.

[0006] In use, align the blade groove on one side of the fixed box with the blade side, and rotate the screw through the motor output to move the moving block inside the moving groove. This, in turn, moves the fixed box and the two grinding wheels outside the blade to grind it. The fixed pipe, spray pipe, and connector facilitate spraying of the ground area, making it more convenient to use. This solves the technical problems of the previous technology, which required periodic disassembly and grinding of the blade, making blade replacement time-consuming, labor-intensive, and inconvenient.

[0007] In a preferred embodiment, the bottom of the connecting frame is symmetrically fixedly equipped with support frames, and the bottom of each support frame is connected to a fixing block by a threaded rod.

[0008] By setting up a support frame, and having a fixing block inside the support frame connected by a threaded rod, it is easy to secure the connecting frame to the operating frame at the blade of the shredder.

[0009] In a preferred embodiment, a limiting groove is formed on the side of the support frame near the fixed block, and a limiting block is fixedly installed on the side of the moving block motor near the limiting groove. The limiting block extends into the limiting groove and is slidably connected to the limiting groove. A fixing rod is fixedly installed inside the limiting groove, and the fixing rod passes through the limiting block and is slidably connected to the limiting block.

[0010] By setting a limit block that extends into the limit groove, and a fixing rod that passes through the limit block and is slidably connected to the limit block, it helps to prevent the fixing block from rotating with the threaded rod, making it more stable in use.

[0011] In a preferred embodiment, a drain pipe is fixedly installed through the bottom of the fixing box.

[0012] By installing a drain pipe that runs through the bottom of the fixed box, it is easier to discharge the wastewater sprayed from the fixed pipe.

[0013] In a preferred embodiment, the side of the fixing block closest to the connecting frame is made of rubber.

[0014] By setting the side of the fixing block closest to the connecting frame to be made of rubber, it is beneficial to protect the work frame that is being fixed.

[0015] In a preferred embodiment, the distance between the two grinding wheels is the same as the thickness of the blade to be ground.

[0016] Setting the distance between the two grinding wheels to be the same as the thickness of the blade to be ground is beneficial for grinding the blade.

[0017] The blade sharpening device for a slicing machine provided by this utility model has the following advantages:

[0018] Firstly, during use, align the blade groove on one side of the fixed box with the blade side. The motor output rotates, driving the lead screw to rotate, which in turn moves the moving block inside the moving groove. This, in turn, moves the fixed box and the two grinding wheels outside the blade to grind it. The fixed pipe, spray pipe, and connector facilitate spraying the grinding area, making it more convenient to use. This solves the technical problems in related technologies where it is necessary to regularly disassemble and grind the blade, and replacing the blade is time-consuming, laborious, and inconvenient.
