Description

Technical Field

[0001] This utility model relates to the field of wood carving technology, and in particular to a wood carving blank edge grinding machine. Background Technology

[0002] A wood carving edge sander is a tool specifically designed for sanding edges and corners in wood carving art and woodworking. It uses a rotating sanding disc or sandpaper to help carvers precisely sand the edges, corners, and other small areas of wood that are difficult to work with by hand. Using a wood carving edge sander can effectively improve work efficiency and reduce irregularities and inaccuracies in edge treatment caused by manual operation.

[0003] In traditional wood carving edge sanding techniques, the grinding discs of the machine require effective protection when not in use. This is because the grinding discs are susceptible to environmental influences when idle, such as impacts, friction, or dust accumulation, which can damage them or degrade their performance. In particular, any bumps, scratches, or wear on the surface of the grinding disc can affect subsequent sanding results, potentially preventing the achievement of the desired wood carving finish. Prolonged exposure to humid or dusty environments can also lead to surface corrosion or clogging, thus affecting the normal operation of the sander. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a wood carving blank edge sanding machine, which aims to improve the problem that the grinding disc of the wood carving edge sanding machine needs to be effectively protected when not in use in the traditional technology.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a wood carving blank edge sanding machine, comprising a machine body, a control switch provided on the top of the machine body, a handle fixedly connected to the outside of the machine body, a drive device fixedly connected to the front end of the machine body, a grinding wheel fixedly connected to the output end of the drive device, a protective mechanism provided on the outside of the grinding wheel for protecting the grinding wheel, a connector slidably connected to the rear end of the machine body, an electric wire fixedly connected to the side of the connector away from the machine body, a slot provided on the outside of the connector, and a locking mechanism provided inside the rear end of the machine body for stably connecting the electric wire;

[0006] The protective mechanism includes a connecting cover, the top of which is slidably connected to the output end of the drive device. A protective cover is slidably connected to the outside of the connecting cover. Two mounting shells are fixedly connected to the outside of the protective cover. A return spring is fixedly connected inside each of the two mounting shells. A limit block is fixedly connected to the opposite side of each of the two return springs. A pin is fixedly connected inside each of the two limit blocks. The opposite sides of each pin penetrate the outside of the protective cover and engage with the connecting cover.

[0007] As a further description of the above technical solution:

[0008] A fixing box is fixedly connected to the top of the mounting shell, a sliding plate is slidably connected inside the fixing box, a baffle plate is fixedly connected to the bottom of the sliding plate, and the bottom of the baffle plate abuts against the top of the limiting block.

[0009] As a further description of the above technical solution:

[0010] The limiting block is slidably connected inside the mounting housing, and the pin passes through both ends of the mounting housing.

[0011] As a further description of the above technical solution:

[0012] A handle is fixedly connected to the side of the pin away from the limiting block.

[0013] As a further description of the above technical solution:

[0014] The engaging mechanism includes a slide rod slidably connected inside the machine body. A slider is fixedly connected to the bottom of the slide rod, and a compression spring is fixedly connected to the bottom of the slider. Both ends of the slider are rotatably connected to connecting rods. A U-shaped frame is fixedly connected to the bottom of each connecting rod, and a locking rod is fixedly connected to the bottom of each U-shaped frame. A clamp is fixedly connected to the opposite side of each locking rod, and both clamps engage with the locking groove.

[0015] As a further description of the above technical solution:

[0016] The slider is slidably connected inside the body, and both connecting rods are slidably connected inside the body.

[0017] As a further description of the above technical solution:

[0018] The bottom of the compression spring is fixedly connected to the inside of the machine body.

[0019] As a further description of the above technical solution:

[0020] A push handle is fixedly connected to the top of the slide rod.

[0021] This utility model has the following beneficial effects:

[0022] 1. In this utility model, when sanding wood carvings, the protective cover is removed, and the drive device is controlled by a control switch to use the grinding wheel for sanding. When the device is not in use, the protective cover needs to be installed on the connecting cover to completely cover the grinding wheel for protection. This achieves the effect of protecting the grinding wheel when the device is not in use, avoiding direct exposure of the grinding wheel to the air and preventing damage, thus extending the service life of the grinding wheel.

[0023] 2. In this utility model, when connecting the wire, the slider is pushed down by the push handle, causing the slider to move downward and compress the compression spring. When the slider moves, the connecting rods on both sides drive the U-shaped frame, causing the two clamps to separate relative to each other. The wire and connector can then slide into the rear end of the machine body. When the push handle is released, the slider moves upward due to the rebound force of the compression spring, causing the two clamps to re-engage and fix with the slot. This achieves a more stable wire connection through the connection mechanism, improving the practicality of the device. Attached Figure Description
