DETAILED DESCRIPTION

[0020] In order to further understand the content, features and effects of the utility model, the following embodiments are given as examples and described in detail with reference to the accompanying drawings.

[0021] like Figures 1 to 4As shown, a knife drum and wood shaving machine provided by an embodiment of the utility model include a machine cover 1. The machine cover 1 is a cylinder with a cavity formed inside the machine cover 1. The machine cover 1 is made of stainless steel. A feed port 15 is fixedly connected to one side of the machine cover 1. The feed port 15 is used to put wood to be shavings into the machine cover 1. A discharge port 16 is fixedly connected to the bottom end of the machine cover 1. The function of the discharge port 16 is to discharge shavings formed by the wood.

[0022] Holes are provided on both sides of the hood 1, and a rotating shaft 2 is provided in the hole. The rotating shaft 2 rotates in the hole.

[0023] A cutter disc 3 is fixedly connected to the rotating shaft 2. The cutter disc 3 is provided with three groups. Of course, the number of the cutter disc 3 is not limited to three groups, and can also be provided with four groups, five groups, etc. The function of the cutter disc 3 is to crush the wood entering the hood 1.

[0024] A connecting rod 4 is rotatably connected to the cutter disc 3, and a blade 5 is fixedly connected to the connecting rod 4. The blade 5 is arranged between every two groups of cutter discs 3. Similarly, the number of blades 5 is not fixed, and can be two groups, three groups, etc. The function of the blade 3 is to shaving the wood crushed by the cutter disc 5.

[0025] The cutter disc 3 and the blade 5 are both arranged in a cavity, and an adjusting chamber 6 is fixedly connected to the inner wall of the cavity. An adjusting component 7 is arranged in the adjusting chamber 6. The adjusting component 7 is used to rotate the connecting rod 4. The adjusting component 7 includes a first motor 701, and the first motor 701 is fixedly connected to the inner wall of the adjusting chamber 6. The output end of the first motor 701 is fixedly connected to the first gear 702.

[0026] An avoidance hole is opened in the middle of the adjusting chamber 6, and the rotating shaft 2 passes through the avoidance hole. The rotating shaft 2 can rotate in the avoidance hole. A second gear 8 is sleeved on the rotating shaft 2, and the second gear 8 is meshed with the first gear 702. A third gear 9 is fixedly connected to one end of the connecting rod 4, and the third gear 9 is meshed with the second gear 8. The third gear 9 and the second gear 8 are both arranged in the adjusting chamber 6.

[0027] After the first motor 701 is started, it drives the first gear 702 to rotate, and the second gear 8 meshing with the first gear 702 rotates accordingly. The second gear 8 will drive the third gear 9 meshing with it to rotate, so that the connecting rod 4 fixedly connected to the third gear 9 rotates, thereby causing the blade 5 to rotate, thereby achieving the purpose of adjusting the angle of the blade 5.

[0028] It also includes a base 10, the hood 1 is fixedly connected to the base 10, and the base 10 is used to fix the device.

[0029] A second motor 11 is fixedly connected to the base 10, a main rotating wheel 12 is fixedly connected to the output end of the second motor 11, a driven rotating wheel 13 is fixedly connected to one end of the rotating shaft 2, a belt 14 is provided on the main rotating wheel 12 and the driven rotating wheel 13, and the other end of the rotating shaft 2 is rotatably connected to the base 10.

[0030] The second motor 11 is started, driving the main wheel 12 to rotate. The main wheel 12 provides power to the driven wheel 13 through the belt 14, thereby driving the driven wheel 13 to rotate. The driven wheel 13 will drive the rotating shaft 2 to rotate. After the rotating shaft 2 rotates, it will drive the cutter disc 3 and the blade 5 to rotate, so that the wood entering the hood 1 is crushed into shavings.

[0031] The working principle of the utility model is as follows:

[0032] When it is necessary to plane the wood, first start the second motor 11, the second motor 11 drives the main wheel 12 to rotate, and then drives the driven wheel 13 to rotate through the belt 14, and the shaft 2 rotates accordingly, so that the cutter disc 3 and the blade 5 in the machine cover 1 rotate. At this time, the wood that needs to be planed is put into the feed port 15, and the wood enters the machine cover 1 through the feed port 15, and is first crushed by the cutter disc 3, and the crushed wood will be planed by the blade 5, and the wood is discharged from the discharge port 16 after the planing is completed.

[0033] When the thickness of the shavings needs to be changed, the second motor 11 is turned off and the first motor 701 is started. After the first motor 701 is started, it drives the first gear 702 to rotate, the first gear 702 drives the second gear 8 to rotate, the second gear 8 drives the third gear 9 to rotate, the third gear 9 drives the connecting rod 4 to rotate, the connecting rod 4 drives the blade 5 to rotate, thereby changing the angle of the blade 5, and thus changing the thickness of the shavings. Then, the above shaving operation is repeated to complete the shaving of the wood.

[0034] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
