During wood processing, the surface of the wood is polished and smoothed to facilitate subsequent production and manufacturing;

[0003] For example, the existing patent CN219310873U discloses a surface grinding device for wood processing. The prior art uses a servo motor to drive a rotating disk to rotate, and a hydraulic cylinder drives the rotating disk to move downward to a specified position. The sandpaper at the bottom of the rotating disk grinds the wood surface, which can be adapted to grinding wood of different thicknesses.

[0004] However, the inventor discovered during the production process that the prior art has the following problems in use: in the prior art, the wood is placed on a rotating roller for transportation; however, there is a lack of a restricting structure when the wood is polished on the rotating roller, which leads to the problem that the wood will inevitably deviate during transportation or polishing. There are situations where the wood surface cannot be polished, which affects the effect of polishing the wood surface. The inventor believes that the prior art has certain disadvantages.

DETAILED DESCRIPTION

[0019] See also Figure 1-4 , the utility model provides the following technical solutions:

[0020] Specifically, it refers to a surface grinding device for wood processing, including a base 1, a top frame 2 is fixedly connected to the base 1, a conveying roller assembly 3 is installed on the base 1, and a surface grinding device is provided on the top wall of the top frame 2. The conveying roller assembly 3 and the surface grinding device are both known technologies in the existing patent: CN219310873U, and no further elaboration is made here;

[0021] When in use, the wood is placed on the conveying roller assembly 3, and the conveying roller assembly 3 conveys the wood to the bottom of the surface grinding device, and the surface grinding device operates to grind and polish the surface of the wood;

[0022] Two control plates 5 are provided on the base 1. Two limiting plates 6 are fixedly connected to the sides of the two control plates 5 near the conveying roller assembly 3. The two limiting plates 6 are located on the upper side of the conveying roller assembly 3 and are symmetrically arranged. Two connecting slides 4 are provided on the upper surface of the base 1. The two connecting slides 4 are horizontally arranged on the base 1. A control cavity 7 is provided in the base 1. The two connecting slides 4 are both connected to the inside of the control cavity 7. The lower sides of the two control plates 5 extend into the control cavity 7 through the two connecting slides 4 respectively and slide in the connecting slides 4. A rotating shaft 8 is rotatably connected between the inner walls on both sides of the control cavity 7. A gear 9 is fixedly sleeved on the rotating shaft 8. Two racks 10 are meshed and connected to the upper and lower sides of the gear 9. The opposite sides of the two racks 10 are fixedly connected to the opposite surfaces of the two control plates 5 respectively.

[0023] When in use, the control shaft 8 rotates, and the gear 9 rotates synchronously with the shaft 8. During the rotation of the gear 9, the two racks 10 can be synchronously meshed and driven in relative directions or opposite directions. At the same time, the two control plates 5 can be displaced synchronously. In this way, the distance between the two limiting plates 6 can be adjusted. When conveying plates of different widths, the two limiting plates 6 limit both sides of the plates, which tries to avoid the problem of plate deviation during conveying and surface grinding, further ensuring the stability of the wood surface during grinding, and ensuring the grinding effect of the wood surface.

[0024] Specifically, a limiting slide bar 11 is fixedly connected between the inner walls on both sides of the connecting slide groove 4, and the control plate 5 is slidably sleeved on the outer surface of the limiting slide bar 11. Therefore, the limiting slide bar 11 forms a limiting and supporting effect on the control plate 5, thereby avoiding the problem of tilting of the limiting slide bar 11 as much as possible.

[0025] Specifically, a worm wheel 12 is rotatably sleeved on the rotating shaft 8, a worm 13 is meshedly connected to the bottom of the worm wheel 12, one end of the worm 13 is rotatably connected to the inner wall of the control cavity 7, and the other end rotates through the outer surface of the base 1, and one end of the worm 13 located outside the base 1 is fixedly connected to a rotating handle 14;

[0026] By rotating the handle 14, the worm 13 can be driven to rotate synchronously, so that the worm wheel 12 can be meshed and driven to rotate, so as to control the rotation of the rotating shaft 8. The worm wheel is used to drive the rotating shaft 8 to rotate, so that the rotating shaft 8 has a certain self-locking effect, and the worm wheel transmission can ensure the adjustment accuracy of the two limiting plates 6.

[0027] Specifically, a movable groove 15 is provided on the surface of one side of the control plate 5 close to the limiting plate 6, and a threaded rod 16 is rotatably connected between the inner walls of the upper and lower sides of the movable groove 15, and a threaded sleeve 17 is threadedly sleeved on the threaded rod 16, and the opposite sides of the threaded sleeve 17 contact and slide with the inner wall of the movable groove 15, and the side of the limiting plate 6 close to the control plate 5 extends into the movable groove 15 and is fixedly connected to the outer surface of the threaded sleeve 17, and the upper end of the threaded rod 16 rotates to penetrate the upper surface of the control plate 5, and the upper end of the threaded rod 16 is also fixedly connected to the rotating handle 13;

[0028] Therefore, by rotating the rotating handle 13, the threaded rod 16 rotates synchronously with the rotating handle 13, and the threaded sleeve 17 can be moved upward or downward under the threaded transmission of the threaded rod 16. At the same time, the limiting plate 6 can be moved synchronously with the threaded sleeve 17, so as to adjust the height of the limiting plate 6, so that the limiting plate 6 can be used to limit plates of different thicknesses.

[0029] Specifically, a through groove 18 is opened on the limiting plate 6, and a plurality of contact rollers 19 are rotatably connected between the upper and lower inner walls of the through groove 18, and the opposite sides of the contact rollers 19 extend into the through groove 18 respectively. Therefore, when the wood is conveyed on the conveying roller assembly 3, the contact rollers 19 contact the surface of the wood. In this way, the contact rollers 19 reduce the friction force of the contact surface between the limiting plate 6 and the wood, and try to avoid the problem of mechanical jamming of the limiting plate 6 when restricting the wood, thereby ensuring the stability of the wood during transportation.

[0030] The working principle of the surface grinding device for wood processing provided by the utility model is as follows: by rotating the rotating handle 14, the worm 13 can be synchronously driven to rotate, so that the worm wheel 12 can be meshed and driven to rotate, thereby controlling the rotation of the rotating shaft 8, and the gear 9 rotates synchronously with the rotating shaft 8. During the rotation of the gear 9, the two racks 10 can be synchronously meshed and driven to move in relative directions or opposite directions, and at the same time, the two control plates 5 can be displaced synchronously.
