Description

Technical Field

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

[0002] Wood is a precious gift from nature, its unique texture and warm feel captivating. Wood sanding is a crucial process in showcasing its beauty; after sanding, the rough surface gradually becomes smooth as silk, revealing the wood's natural grain clearly under your fingertips. When the final polishing is completed, the wood surface gleams with a soft sheen, feeling warm and delicate to the touch, as if it has been given new life. This is not only a refinement of skill, but also a profound dialogue between humanity and nature.

[0003] Currently, most wood sanding processes utilize conveyor belts and top-mounted sanding rollers in an assembly line manner. While this process allows for continuous operation, it only allows sanding one side at a time. Each piece of wood must be manually flipped after one side is finished before the other side can be processed, increasing the number of steps and reducing overall efficiency. Frequent flipping is not only labor-intensive but also increases the risk of surface damage due to repeated handling. Utility Model Content

[0004] (a) Technical problems to be solved

[0005] In view of the problems existing in the prior art, this utility model provides a wood sanding device to solve the technical problem mentioned in the background art that the existing wood sanding device can only sand one side of the wood and cannot simultaneously sand both sides, thus affecting the efficiency of wood sanding.

[0006] (II) Technical Solution

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A wood-processing sanding device includes a conveyor frame, on which an upper conveyor roller and an lower conveyor roller are mounted. A drive structure is provided on the conveyor frame in conjunction with the upper and lower conveyor rollers. A pressing conveyor roller is vertically mounted above both the upper and lower conveyor rollers. An upper sanding roller and a lower sanding roller are symmetrically arranged between the upper and lower conveyor rollers. Support frames are symmetrically arranged at the top and bottom of the conveyor frame. A first electric push rod is mounted on the support frame. A mounting frame is provided at the output end of the first electric push rod. The upper and lower sanding rollers are mounted on corresponding mounting frames via bearings, and sanding motors are mounted on the mounting frames corresponding to the upper and lower sanding rollers.

[0009] The present invention is further configured such that a movable groove is provided on the support frame, and the mounting frame is slidably located in the movable groove. The movable groove enables flexible installation of the grinding motor, allowing the grinding motor to be located on the outside of the support frame. At the same time, the movable groove and the mounting frame cooperate to achieve initial movement limitation of the mounting frame.

[0010] The present invention is further configured such that a limiting groove is provided on the side wall of the moving groove, and a limiting slider is provided on the side of the mounting frame. The limiting slider slides within the limiting groove. The cooperation between the limiting groove and the limiting slider can improve the moving stability of the mounting frame within the moving groove, thereby improving the stability of the upper and lower grinding rollers during use.

[0011] The present invention is further configured such that both ends of the upper and lower grinding rollers are provided with mounting shafts, and the mounting shafts are mounted on the conveyor frame through bearings, thereby achieving stable installation of the upper and lower grinding rollers on the conveyor frame.

[0012] The present invention is further configured such that one of the mounting shafts extends outward to the outside of the conveyor frame, the drive structure includes a drive motor, the drive motor is mounted on the conveyor frame and is connected to the extension end of one of the mounting shafts, and a synchronous belt drive structure is provided between two adjacent mounting shafts. When the drive motor is started, the cooperation between the drive motor and the synchronous belt drive structure can control the synchronous rotation of multiple mounting shafts, thereby realizing the synchronous rotation of the feeding conveyor roller and the unloading conveyor roller, so as to realize the conveying of wood during sanding.

[0013] The present invention is further configured such that both the feeding conveyor roller and the unloading conveyor roller are fitted with conveyor belts, which can achieve the stability of the wood conveying on the conveyor frame during sanding, feeding and unloading.

[0014] The present invention is further configured such that a second electric push rod is provided on the top support frame, the second electric push rod is located on both sides of the first electric push rod, and a pressing frame is provided at the bottom end of the second electric push rod. The pressing conveying roller is mounted on the pressing frame through a bearing. When the second electric push rod is activated, the pressing frame is moved by controlling the pressing frame, so that the pressing frame can drive the pressing conveying roller to descend, thereby pressing the wood on the conveyor belt. This can improve the conveying stability of the wood during the sanding process, so that the conveying power applied to the wood by the pressing conveying roller, the feeding conveying roller, the unloading conveying roller and the conveyor belt is greater than the friction force of the upper and lower sanding rollers when sanding the wood, thereby achieving stable conveying of the wood during sanding.

[0015] The present invention is further configured such that a dust collection hood is provided on one side of the mounting frame, and a dust collection pipe is connected to the dust collection hood. The output end of the dust collection pipe is connected to an external negative pressure dust collection device. In this way, the dust generated during the sanding process of the sanding roller on the wood can be absorbed by the dust collection hood in time and transported to the external negative pressure dust collection device for collection through the dust collection pipe, thereby reducing the dust flying during the wood sanding process and improving the cleanliness of the operation.

[0016] (III) Beneficial Effects

[0017] Compared with the prior art, the present invention provides a sanding device for wood processing, which has the following beneficial effects:

[0018] 1. This utility model features an upper and lower grinding roller mounted on a conveyor frame. These rollers are connected to a support frame, a first electric push rod, a mounting frame, and a grinding motor. During wood grinding, the first electric push rod controls the movement of the mounting frame, which in turn moves the upper and lower grinding rollers. The grinding motor then controls the rotation of the upper and lower guide rollers, achieving simultaneous grinding of the top and bottom of the wood during transport. This improves the grinding effect.

[0019] 2. This utility model is equipped with a feeding conveyor roller and a discharging conveyor roller on the conveyor frame, which are used to feed and discharge wood during sanding, respectively. A pressing conveyor roller can be raised and lowered above both the feeding and discharging conveyor rollers. In use, the drive motor is started, and through the cooperation of the drive motor and the synchronous belt transmission structure, multiple mounting shafts can be controlled to rotate synchronously, thereby achieving synchronous rotation of the feeding and discharging conveyor rollers, which in turn moves the corresponding conveyor belt to facilitate the conveying of wood during sanding. During this process, the second electric push rod is activated, which controls the movement of the pressing frame, causing it to lower the pressing conveyor roller, thus pressing the wood on the conveyor belt. This improves the conveying stability of the wood during sanding, ensuring that the conveying force applied to the wood by the pressing conveyor roller, the feeding conveyor roller, the discharging conveyor roller, and the conveyor belt is greater than the frictional force exerted by the upper and lower sanding rollers during sanding, thereby achieving stable conveying of wood during sanding.

[0020] 3. This utility model has a movable groove on the support frame, which allows the mounting frame to slide within the movable groove. The grinding motor is located on the outside of the support frame and mounted on the mounting frame. This allows for flexible adjustment of the upper and lower grinding rollers, thereby flexibly adjusting the wood grinding pressure. Attached Figure Description
