[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] Please see Figures 1-4 In this embodiment of the utility model, a polishing device for wooden door production includes a workbench 1, a polishing seat 2 slidably mounted on the upper part of the workbench 1, a polishing wheel 3 for polishing the door panel connected to the bottom of the polishing seat 2, a drive motor 4 for providing power on one side of the workbench 1, and a transmission mechanism 5 mounted on the workbench 1 and the drive motor 4.

[0031] The transmission mechanism 5 includes a conveying unit and a transmission unit;

[0032] The conveying unit is used to provide power for conveying the door panels on the upper surface of the workbench 1;

[0033] The transmission unit is used to provide power for the axial reciprocating movement of the polishing seat 2;

[0034] The conveying unit includes a first conveying roller 501, a transmission rod 502, and a second conveying roller 503;

[0035] The first conveying roller 501 is connected to the output end of the drive motor 4 via a shaft, a rotating shaft, and a coupling, and is rotatably sleeved with the top protrusion of the worktable 1. The first conveying roller 501 is used to provide conveying power to the door panel below.

[0036] The transmission rod 502 is eccentrically rotatably connected to the end of the first conveying roller 501, and the transmission rod 502 is used to synchronously drive the second conveying roller 503 connected to the other end to rotate.

[0037] The second conveying roller 503 is rotatably sleeved above the worktable 1 via a shaft and located at the other end of the polishing seat 2. The second conveying roller 503 is used to provide conveying power for the removal of the door panel.

[0038] The transmission unit includes a chain 504, a driven sprocket 505, a transmission wheel 506, a guide groove 507, and a force-bearing rod 508;

[0039] Chain 504 is sleeved on the outer wall of the shaft of the first conveying roller 501 via a drive sprocket, and chain 504 is used to synchronously drive the driven sprocket 505 to rotate.

[0040] The passive sprocket 505 is mounted on the top of the workbench 1 via a mounting base. The passive sprocket 505 is used to synchronously drive the transmission wheel 506 to rotate.

[0041] The drive wheel 506 is fixed to the outer wall of the driven sprocket 505, and the drive wheel 506 is used to synchronously drive the guide groove 507 to rotate circumferentially.

[0042] The force-bearing rod 508 is fixed to the bottom end of the polishing seat 2 and extends to the inner side of the guide groove 507. The force-bearing rod 508 is used to receive the rotational thrust from the guide groove 507.

[0043] In this embodiment: By placing the template to be polished on the upper surface of the workbench 1, the upper surface of the door panel contacts the first conveyor roller 501. By starting the drive motor 4, the drive motor 4 synchronously drives the first conveyor roller 501 to rotate. The rotating first conveyor roller 501 provides a pushing force to the door panel below, causing the door panel to move downwards towards the polishing seat 2 and the polishing wheel 3. The polishing wheel 3 polishes the upper surface of the incoming door panel. Simultaneously, the rotation of the first conveyor roller 501 also synchronously drives the drive sprocket fixed to the outer wall to rotate, causing the chain 504 sleeved on the drive sprocket to drive the transmission. 504 synchronously drives the passive sprocket 505 to rotate, and the transmission wheel 506 fixed on the outer wall of the passive sprocket 505 will also rotate synchronously. This causes the guide groove 507 on the outer wall of the transmission wheel 506 to move circumferentially with the rotation of the transmission wheel 506. When the inclined guide groove 507 moves circumferentially, the connection point with the force rod 508 will also be subjected to the axial thrust from the guide groove 507 and move back and forth axially. This drives the polishing wheel 3 and the polishing seat 2 to move back and forth axially. The polishing wheel 3, which moves back and forth axially, performs horizontal grinding and polishing on the upper surface of the door panel, reducing the number of drive units and further reducing costs.

[0044] Please refer to this carefully. Figures 1-4The guide groove 507 is in a ring shape and is inclinedly distributed on the outer wall of the transmission wheel 506. The bottom of the force rod 508 has a spherical structure in contact with the guide groove 507. The inner side of the guide groove 507 matches the bottom outer wall of the force rod 508. The two ends of the transmission rod 502 are eccentrically rotatably connected to the outer walls of the first conveying roller 501 and the second conveying roller 503, respectively. The two ends of the transmission rod 502 are equidistant from the axis of the first conveying roller 501 and the second conveying roller 503. Multiple polishing wheels 3 are provided and are evenly distributed on the bottom of the polishing seat 2.

[0045] In this embodiment: With this structure, when the first conveying roller 501 rotates with the operation of the drive motor 4, the first conveying roller 501 will synchronously drive one end of the transmission rod 502 at the end to rotate circumferentially. Then, the second conveying roller 503, which is eccentrically connected to the other end of the transmission rod 502, will also rotate synchronously. The rotating second conveying roller 503 rotates in the same direction as the first conveying roller 501, so that the door panel that has moved out from the other end of the polishing seat 2 comes into contact with the second conveying roller 503 and is pushed out from under the polishing seat 2 by the second conveying roller 503, thus completing the door panel discharge operation. It should be noted that the top of each polishing wheel 3 is connected to a working motor through a rotating shaft and a coupling.

[0046] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
