Description

Technical Field

[0001] The utility model belongs to the technical field of furniture manufacturing, in particular to a polishing device for furniture manufacturing. Background Art

[0002] Furniture refers to a large category of equipment and facilities that are essential for humans to maintain normal life, engage in production practices and carry out social activities. Furniture is mostly made of wood. During the production and manufacturing of furniture, it needs to go through processes such as material selection, polishing, drilling, splicing, and painting. In order to make the surface of the wood smooth and better for painting, polishing is an indispensable process. In real life, when using a polishing device to polish wood, since most polishing devices are not equipped with a protective mechanism, the fine wood chips generated during the polishing process will fly into the air, which not only affects the environment, but may also be inhaled by the human body, causing harm to the human body.

[0003] A Chinese patent document (application publication number CN217776625U) discloses a board polishing device for furniture manufacturing, which includes a fixed base, a fixed stand and a mobile polishing device. The mobile polishing device includes a driving motor, a rotating transmission screw, a screw support plate, a support plate slide, a support plate slider, a mobile support plate, a board fixing table, a hydraulic rod support, a telescopic hydraulic rod, etc.

[0004] It can be seen that the patent document cited above also has the same problem. It lacks a protective mechanism, so that the fine wood chips generated during the polishing process will fly into the air, which not only affects the environment, but may also be inhaled into the human body and cause harm to the human body.

[0012] As a preferred embodiment, the outer diameter of the polishing disk is smaller than the inner wall length of the protective plate.

[0013] Compared with the prior art, the technical effects and advantages of the utility model are as follows:

[0014] The polishing device for furniture manufacturing benefits from the design of the knob, the screw rod, the connecting block and the protective plate. Before polishing, the two knobs are rotated respectively, and the rotation of the knobs drives the screw rod to rotate, and then the protective plate is driven to move through the connecting block until one side of the two protective plates are in contact. The protective plates can be used to protect the wood during polishing, so as to prevent the fine wood chips generated by polishing from flying into the air, thereby protecting the environment and the human body. At the same time, after polishing is completed, the two protective plates can be opened to facilitate cleaning of the inner wall thereof.

[0015] By providing a pull block, a clamping sleeve, a clamping rod and a clamping block, the pull block is pulled outward until the clamping rod is separated from the clamping block, and then the polishing disc is taken out downward. Similarly, a new polishing disc is clamped into the clamping sleeve and fixed by the clamping rod. This makes it convenient to replace the polishing disc, and the replacement process does not require the aid of auxiliary tools, saving time and effort. BRIEF DESCRIPTION OF THE DRAWINGS

The rotation of the knob 8 drives the screw rod 7 to rotate. The screw rod 7 rotates and drives the protective plate 10 to move through the connecting block 9 until one side of the two protective plates 10 contacts each other. Then, polishing is performed through the polishing assembly. The protective plate 10 can be used for protection during wood polishing to prevent fine wood chips generated by polishing from flying into the air, thereby protecting the environment and human body. At the same time, after polishing is completed, the two protective plates 10 can be opened to facilitate cleaning of the inner wall. When the polishing disc 16 needs to be replaced, the pull block 19 is pulled outward, and the pull block 19 stretches the spring 18 until the clamping rod 14 is separated from the clamping block 15. After the polishing disc 16 is removed, the new polishing disc 16 is similarly engaged in the clamping sleeve 13 and fixed by the clamping rod 14. This facilitates the replacement of the polishing disc 16, and the replacement process does not require the aid of auxiliary tools, saving time and effort.
