Description

A wood floor sanding and polishing device Technical Field

[0001] This utility model relates to the field of wood flooring processing technology, specifically to a wood flooring sanding and polishing device. Background Technology

[0002] Wood floor sanding equipment is a type of machinery specifically designed for sanding and polishing the surface of wood floors. It mainly consists of a sanding mechanism, a conveying system, an adjusting mechanism, and a dust extraction and cooling system. When using it, first turn on the power switch, start the equipment, and adjust the sanding table height to ensure good contact between the wood floor and the sanding belt or sandpaper. During the sanding process, carefully observe the sanding effect on the wood floor surface and adjust the sanding speed and pressure as needed. After sanding, turn off the power and clean the dust and debris from the equipment surface and surrounding area. Wood floor sanding equipment is widely used by wood floor manufacturers, construction teams, and in home renovations.

[0003] For example, Chinese patent CN217413421U, entitled "A Sanding Equipment for Solid Wood Flooring," describes a base box with a processing machine in the middle. A controller is mounted on the surface of the base box, and a base is mounted at the bottom of the controller. Two sanding rollers are mounted at the front top of the base box, and rotating rods are mounted at the bottom of the sanding rollers. A sliding block is mounted at one end of the rotating rod, and side blocks are mounted at both ends of the sliding block. A screw is mounted on the surface of one side block, and one end of the screw extends out of the base box and is equipped with a motor. A cover is rotatably mounted on both sides of the top of the base box. A dust-collecting block is mounted on one side of the inner end of each cover, and a connecting pipe is mounted at the bottom of each dust-collecting block. A vacuum cleaner is mounted at the other end of each connecting pipe.

[0004] While the existing technologies can achieve wood floor sanding, in practical use, the sanding devices are inconvenient to use. Usually, when sanding wood floors, it is necessary for personnel to manually pull and move the wood floor, which requires manual assistance for each wood floor, thus increasing the workload of the operators. On the other hand, the clamping mechanism is difficult to adjust in position. Usually, the clamping mechanism is fixed on the device, which means that larger wood floors need to be replaced with a suitable sanding device, thus reducing the sanding efficiency of wood floors. Therefore, it does not meet the current needs. In response, we propose a wood floor sanding and polishing device. Summary of the Invention

[0005] The purpose of this utility model is to provide a wood floor sanding and polishing device to solve the problems mentioned in the background art, such as the sanding device being inconvenient to use and the clamping mechanism being difficult to adjust in position.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a wood floor sanding and polishing device, comprising a base, with support rods fixedly installed at the four corners of the lower end of the base, a sliding groove provided at the center of the interior of the base, the sliding groove being a through structure, a drive cavity provided at both the front and rear ends of the interior of the base, the drive cavity communicating with the sliding groove, a lead screw provided inside the drive cavity, both sides of the lead screw being rotatably connected to the inner wall of the drive cavity, a movable seat provided inside the sliding groove, the movable seat slidingly engaging with the sliding groove, and the protrusions at the front and rear ends of the movable seat extending into the drive cavity and sleeved on the outside of the lead screw, and hydraulic telescopic devices fixedly installed at the four corners of the upper end of the movable seat, with a placement platform fixedly installed at the upper end of the hydraulic telescopic device.

[0007] Preferably, servo motors are fixedly installed at both the front and rear ends on one side of the base, and the output shaft of the servo motor extends into the interior of the drive cavity and is fixedly connected to the lead screw.

[0008] Preferably, the front and rear ends of both sides of the placement platform are provided with clamping cavities. The clamping cavities are open structures, and the inside of the clamping cavities is provided with extrusion plates, which slide in cooperation with the clamping cavities.

[0009] Preferably, the extrusion plate has a first threaded hole inside, which is a through-hole structure. The placement platform has a second threaded hole inside on one side of the clamping cavity. The second threaded hole corresponds to the position of the first threaded hole. A bolt is installed inside the first threaded hole, and one end of the bolt extends into the second threaded hole.

[0010] Preferably, a fixing frame is fixedly provided at the upper end of the base, and mounting frames are fixedly provided on both sides of the fixing frame. A dust suction plate is fixedly provided at the lower end of the mounting frame, and the dust suction plate is connected to the pipe inside the mounting frame. A connecting pipe is fixedly provided at the upper end of the mounting frame, and the connecting pipe is connected to the pipe inside the mounting frame.

[0011] Preferably, a grinding cylinder is provided at the lower end of the fixed frame, and a drive motor is fixedly provided at both the front and rear ends of the fixed frame. The output shaft of the drive motor passes through the fixed frame and is fixedly connected to the grinding cylinder.

[0012] Preferably, the upper end of the placement platform is provided with a wooden floor, and the extrusion plate contacts the side of the wooden floor.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] (1) This utility model can adjust the position of the wood flooring by using a lead screw and a hydraulic telescopic device. When the wood flooring is being sanded, the wood flooring is already fixed. At this time, the servo motor is turned on, so that the output shaft of the servo motor drives the lead screw to rotate. The lead screw drives the fixed block fixedly connected to the moving seat to move. At the same time, the moving seat moves in the slide groove. The position of the wood flooring in the horizontal direction is adjusted by the moving seat. At the same time, the hydraulic telescopic device is turned on, so that the telescopic end of the hydraulic telescopic device extends. The extension of the telescopic end of the hydraulic telescopic device drives the placement platform and the wood flooring to move upward together until the wood flooring is moved to the appropriate position. At this time, the sanding operation is carried out. During the sanding process, the servo motor is turned on again, and the sanding position of the wood flooring is adjusted by the servo motor, thereby simplifying the movement steps of the wood flooring during the sanding process.

[0015] (2) The present invention can adjust the extrusion plate to a suitable position through the bolt and the second threaded hole. Before sanding the wood floor, the wood floor is placed on the placement table. At this time, the operator puts the extrusion plate into the clamping cavity so that the extrusion plate contacts the wood floor. Then, a suitable bolt is selected and rotated to align with the opening of the first threaded hole so that one end of the bolt extends through the first threaded hole into the second threaded hole. The bolt is then rotated to move through the thread into the second threaded hole until the bolt is rotated to a suitable position. At this time, the extrusion plate presses and fixes the side wall of the wood floor, thereby improving the flexibility of the clamping mechanism position adjustment.

[0016] (3) This utility model can process the wood chips generated during the sanding of wood flooring by using a connecting pipe and a dust suction plate. When sanding the wood flooring, the wood flooring has been moved to a suitable position. At this time, the external air pump is turned on, and the air near the dust suction plate is accelerated and sucked in through the air pump and connecting pipe. At this time, the wood chips on the surface of the wood flooring are sucked into the connecting pipe. As the wood flooring moves, the wood chips generated during the sanding of the wood flooring are all sucked into the connecting pipe until the sanding of the wood flooring is completed. At this time, the operator will collect and process the wood chips, thereby improving the cleanliness of the sanding environment of the wood flooring. Attached Figure Description
