Technical Field
[0001] The utility model relates to the technical field of furniture manufacturing, in particular to a surface grinding device for wooden furniture. Background Art
[0002] In the furniture making industry, whether it is the early preparation of wood raw materials or the subsequent assembly and fine processing, various auxiliary tools and equipment are needed.
[0003] After the assembly of wooden furniture is completed, such as the table top, it needs to be finely polished before it can be painted. Although there is a process of polishing the surface of the wood material when preparing the wood material for the table top, the table top will inevitably be affected during the subsequent assembly and other processes. At the same time, in order to increase the flatness and smoothness of the entire table top, it still needs to be polished after it is made.
[0004] Since wooden furniture such as tables become larger after assembly, it is impossible to move the entire table product or place it on the grinding equipment for grinding. Only relatively small grinding equipment can be used directly on the desktop for operation. Although handheld grinding equipment is convenient, it is easily affected by human factors during grinding. It is also common to miss grinding positions or cause local excessive grinding losses. It is impossible to achieve accurate and uniform grinding without omissions.
[0005] Therefore, we propose a grinding device, which is mainly used for grinding the surface of furniture, so as to solve the above technical problems. Utility Model Content
[0006] The purpose of the utility model is to provide a wooden furniture surface polishing device to solve the problems raised in the above background technology.
[0007] In order to achieve the above purpose, the utility model provides the following technical solutions:
[0008] A surface polishing device for wooden furniture comprises a protective shell, wherein a driving shaft and a movable shaft are respectively connected through the left and right sides of the protective shell, an adjusting shaft is installed through the side of the protective shell between the driving shaft and the movable shaft, a roller is mounted on the outer ring of the driving shaft, the movable shaft and the adjusting shaft located in the inner cavity of the protective shell, a polishing belt is tightly mounted on the outer ring of the roller, a motor is installed on the left side of the side of the protective shell, and the output shaft of the motor is docked with the driving shaft.
[0009] Preferably, the bottom of the protective shell is in an open state, and the lower surface of the grinding belt is located on the outer side of the bottom of the protective shell.
[0010] Preferably, both ends of the right side of the protective shell are provided with sliding grooves, and both sides of the middle part of the protective shell are provided with lifting grooves.
[0011] Preferably, the sliding groove at the front position and the inner walls of the two lifting grooves are provided with card slots, the inner cavity of the sliding groove at the back position is provided with a convex groove, and the inner wall of the lifting groove at the back position is provided with a receiving groove.
[0012] Preferably, clamping strips are provided on the front side of the outer wall of the movable shaft and on both ends of the outer wall of the adjusting shaft.
[0013] Preferably, a limiting ring is arranged on the back of the outer ring of the movable shaft, a tension spring is mounted on the back of the outer ring of the movable shaft, and the tension spring is located between the convex groove and the limiting ring, and pull rings are arranged on the front of the movable shaft and the adjusting shaft.
[0014] Compared with the prior art, the beneficial effects of the utility model are:
[0015] 1. The wooden furniture surface polishing equipment uses a protective shell with an open bottom, a motor, and a polishing belt extending from the bottom of the protective shell. When the desktop is finally polished, the desktop is directly polished in a horizontal manner, which can achieve one-time surface polishing without omissions. At the same time, it can also ensure that the polishing time and polishing intensity of each part of the desktop are the same, which effectively solves the problem of omissions in the prior art of hand-held polishing of the assembled desktop and the poor control of the polishing intensity and time, which easily leads to uneven quality of furniture products.

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0025] Embodiment: The utility model provides a technical solution for a wooden furniture surface polishing device:
[0026] like Figure 1 and Figure 2 As shown, it mainly includes a protective shell 1, a driving shaft 2 is penetrated through the left side of the protective shell 1, a movable shaft 3 is penetrated through the right side of the protective shell 1, an adjusting shaft 4 is penetrated and installed between the movable shaft 3 and the driving shaft 2, a roller 5 is mounted on the outer ring of the movable shaft 3, the adjusting shaft 4 and the driving shaft 2, a grinding belt 6 is mounted on the outer ring of the roller 5, and a motor 7 is installed at one end of the driving shaft 2 of the protective shell 1, and one end of the driving shaft 2 is docked with the output shaft of the motor 7.
[0027] The bottom of the protective shell 1 is in an open state, and the bottom of the grinding belt 6 is located outside the bottom of the protective shell 1 .
[0028] In this embodiment, when it is actually used, the plug of the motor 7 is directly plugged into the socket in the processing area, and then the whole device is placed flat on the table to be polished, and the placement state is preferably parallel to the short side. In this way, after the polishing equipment is placed, the bottom of the polishing belt 6 can completely cover the short side of the table. Then the motor 7 is started, and the motor 7 drives the drive shaft 2 to rotate through the output shaft. When the drive shaft 2 rotates, it drives the roller 5 on it to rotate. When the roller 5 rotates, it drives the polishing belt 6 to circulate. When the polishing belt 6 circulates, its bottom is squeezed with the table. The desktop is polished by the rotation of the polishing belt 6 because the polishing belt 6 is in pressure contact. When polishing, the entire device is placed flat on the desktop, so the polishing device can be pushed along the long side of the desktop and moved continuously until it moves to the other end of the desktop. After the movement is completed, the desktop is polished. Moreover, since the polishing belt 6 completely covers the polishing area, polishing without omission can be achieved. The tension of the polishing belt 6 is exactly the same, so the same polishing force can be achieved, which effectively solves the problem of omission and uneven polishing degree when handheld polishing equipment is used for desktop polishing.
[0029] Embodiment 2:
[0030] like Figure 3 As shown, sliding grooves 8 are provided on both sides of the side of the protective shell 1 , and lifting grooves 9 are provided on both sides of the middle of the protective shell 1 .

[0032] Both ends of the adjusting shaft 4 are inserted into the inner cavity of the lifting slot 9. The two lifting slots 9 and the inner wall of the movable slot 8 on the front are provided with a positioning slot 13. The front of the outer ring of the movable shaft 3 and both ends of the outer ring of the adjusting shaft 4 are integrally provided with a positioning strip 14.
[0033] Among them, the lifting slot 9 located at the back is as follows Figure 5 and Figure 6 As shown, a vertical receiving slot is provided at the rear of the card slot 13 .
[0034] Among them, pull rings 10 are fixedly installed on the front sides of the adjustment shaft 4 and the movable shaft 3.
[0035] In this embodiment, based on the first embodiment, when the horizontal length of the grinding belt 6 in the initial state is not enough for the shortest side width of the desktop, the adjusting shaft 4 is first pulled by the pull ring 15 to separate the clamping strips 14 at both ends from the clamping slots 13, wherein the clamping strip 14 at the front side is directly separated from the protective housing 1, and the clamping strip 14 at the back side directly enters the receiving slot;
[0036] Then, the movable shaft 3 is pulled by the pull ring 15, and the clamping strip 14 on the movable shaft 3 is separated from the clamping slot 13. During the pulling process, the limit ring 11 gradually compresses the tensioning spring 12. After that, the position of the movable shaft 13 can be adjusted, that is, the cross-width of the grinding belt 6 can be adjusted according to the size of the desktop. Finally, the adjustment shaft 4 is reinserted into the lifting slot 9, and then the movable shaft 3 is released. The movable shaft 3 is reset and fixed in position by the tensioning spring 12 to meet the grinding work of desktops of different sizes.
