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.

[0020] See also Figures 1 to 3 The utility model provides a technical solution: a multi-axis belt grinding device, comprising a base 6, a top side of the base 6 is vertically connected with a mounting vertical plate 25, a top side of the mounting vertical plate 25 is fixedly connected with a mounting horizontal plate 8, an L-shaped structure is formed between the mounting horizontal plate 8 and the mounting vertical plate 25, and the mounting vertical plate 25 is rotatably connected to two first connecting shafts 9 from top to bottom, and at least three first driven wheels 10 are equidistantly connected to the first connecting shaft 9 along the axial direction;

[0021] In actual use, the installation horizontal plate 8 and the installation vertical plate 25 are an integrated structure, and the bottom of the installation vertical plate 25 is fastened to the base 6 by welding or bolt fastening.

[0022] An L-shaped plate 16 is fixedly connected to one side of the mounting horizontal plate 8 away from the mounting vertical plate 25, and at least three second driven wheels 19 are equidistantly connected to the L-shaped plate 16 through an adjusting mechanism. A motor 24 is fixedly connected to the top of the base 6 through a motor mounting seat 11, and a second connecting shaft 12 is fixedly connected to the output end of the motor 24, and at least three driving wheels 13 are equidistantly connected to the second connecting shaft 12, and the radius of the driving wheel 13 decreases from one side of the motor 24 to the outside.

[0023] The spacing between the first driven wheels 10 is equal to the spacing between the driving wheels 13, and a sanding belt 4 is connected between the driving wheel 13, the first driven wheel 10, and the second driven wheel 19 located on the same plane, and the mesh count of the sanding belt 4 increases successively. The top of the base 6 is fixedly connected to the shell 1, and the mounting horizontal plate 8 and the mounting vertical plate 25 are located in the shell 1. A rectangular opening 3 is opened on one side of the shell 1, and the rectangular opening 3 is located between the two first connecting shafts 9.

[0024] During the actual installation process, the ends of the first connecting shaft 9 and the second connecting shaft 12 are connected to the housing 1 through bearings, which ensures the normal rotation of the first connecting shaft 9 and the second connecting shaft 12. Since the radius of the driving wheel 13 decreases successively, the length of the connected sanding belt 4 decreases successively, which can achieve different degrees of grinding. At the same time, the sanding belt 4 with gradually decreasing length is convenient for replacement when it is damaged, thereby improving the practicability of the device.

[0025] Furthermore, the adjustment mechanism includes a U-shaped mounting seat 17, a second driven wheel 19 is connected to the U-shaped mounting seat 17 through a third connecting shaft 18, a screw rod 15 is rotatably connected to the bottom of the U-shaped mounting seat 17, the lower end of the screw rod 15 passes through the L-shaped plate 16 and is rotatably connected thereto, a guide rod 20 is symmetrically connected to the bottom of the U-shaped mounting seat 17, and the bottom of the guide rod 20 passes through the L-shaped plate 16. In order to prevent the screw rod 15 from automatically rotating due to mechanical vibration, a matching nut is provided on each screw rod 15. When the screw rod 15 is adjusted to a preset height, the screw rod and the L-shaped plate 16 can be fastened by a nut.

[0026] like Figure 2 As shown, by rotating the screw rod 15, the U-shaped mounting seat 17 can be driven to rise and fall, so that the tension of the sanding belt 4 can be adjusted to avoid the sanding belt 4 being too tight or too loose, thereby ensuring normal sanding of the device.

[0027] Furthermore, the bottom of the screw rod 15 is fixedly connected with a rotating seat 21, and the outer wall of the rotating seat 21 is symmetrically connected with an extension block 14 extending outward. The rotating seat is a special-shaped structure, such as a butterfly-shaped structure, a strip-shaped structure, etc., which is convenient for holding the rotating seat 21 to rotate.

[0028] like Figure 2 As shown, the adjustment mechanism formed by the extension block 14 and the rotating seat 21 facilitates the user to rotate the screw rod 15 .

[0029] Furthermore, a side plate 23 is fixedly connected to the side wall of the mounting vertical plate 25, and the side plate 23 and the side wall of the first driven wheel 10 are on the same plane. The side plate 23 contacts the inner side of the sanding belt 4, and the side plate 23 can support the sanding belt 4 to facilitate the sanding operation.

[0030] Furthermore, the bottom of the mounting cross plate 8 is fixedly connected to the top of the base 6 via the reinforcing plate 22 , thereby improving the overall stability of the mounting cross plate 8 and the mounting vertical plate 25 .

[0032] In summary, when the multi-axis abrasive belt grinding device is used, the workpiece to be ground is placed at the rectangular opening 3, and the workpiece is supported by the top of the support platform 5, and the workpiece is brought into contact with the surface of the abrasive belt 4 to achieve grinding, and because the mesh number of the abrasive belt 4 increases successively, different degrees of grinding can be achieved, thereby improving the practicality of the device;

[0033] In actual use, an opening is provided on the side wall of the housing 1, and an inspection door ( Figure 1 The inspection door and the opening are connected by a lock, and the inner sanding belt 4 can be replaced after the inspection door is opened. Since the diameter of the driving wheel 13 gradually decreases, the length of the sanding belt 4 decreases from the motor 24 side to the outside, thereby facilitating the replacement of the inner sanding belt 4 and facilitating the operation of the staff.
