Description

Technical Field

[0001] This utility model relates to the field of belt grinding devices, and more particularly to an adjustable belt grinding machine. Background Technology

[0002] Abrasive cloth (abrasive belts) are widely used for grinding and polishing materials such as metal, wood, ceramics, plastics, leather, rubber, and furniture manufacturing. Specifically, abrasive belts can be directly driven by a motor, achieving grinding and polishing while rotating. Currently, in applications, the polishing wheel driving the abrasive belt can generally only slide up and down for adjustment. If different areas of the material need to be ground and polished, only the material's position can be adjusted. If the material is too heavy / large or irregularly shaped, it is inconvenient to adjust its position, leading to poor grinding results. Furthermore, different abrasive belts have varying degrees of adhesion between the adhesive and abrasive grains, placing strict requirements on the grinding angle and force. Therefore, complete sets of equipment for abrasive belt processing face higher structural and adjustment requirements in terms of process switching convenience and grinding posture / force stability to adapt to the continuous and stable grinding needs under different grit sizes and working conditions. Utility Model Content

[0003] The purpose of this invention is to overcome the shortcomings of the existing technology and provide an adjustable belt grinding machine.

[0004] To achieve the above objectives, the following solution is adopted:

[0005] An adjustable belt grinder, the grinder comprising:

[0006] The frame includes a first crossbeam and two columns for fixing to the ground and supporting the first crossbeam. The first crossbeam is provided with a first arc-shaped connecting plate and a second arc-shaped connecting plate, and the second arc-shaped connecting plate has an arc-shaped through groove.

[0007] The second crossbeam has a vertical plate on it. The bottom of the vertical plate is rotatably connected to one end of the first arc-shaped connecting plate, and the top of the vertical plate is rotatably connected to the second arc-shaped connecting plate. The connecting bolts between the vertical plate and the second arc-shaped connecting plate can slide along the arc-shaped through groove.

[0008] The main wheel is disposed at one end of the second crossbeam;

[0009] The motor is located at the other end of the second crossbeam, and its drive end is connected to the main wheel via a sanding belt and covers the surface of the main wheel;

[0010] A tension wheel is disposed above the second crossbeam and between the motor and the main wheel, and is used to adjust the tension of the sanding belt;

[0011] A workbench is disposed at one end of the first crossbeam and located on one side of the main wheel.

[0012] Furthermore, the first crossbeam is a square tube, and the worktable is slidably mounted in the first connecting frame, which is inserted into one end of the first crossbeam and fixed with bolts. Based on the first connecting frame, the worktable can move back and forth and up and down, facilitating adjustment of the grinding position.

[0013] Furthermore, the second crossbeam is a square tube, and the main wheel is rotatably connected to the second connecting frame. The second connecting frame is inserted into one end of the second crossbeam and fixed with bolts. The motor is connected to the third connecting frame, which is inserted into the other end of the second crossbeam and fixed with bolts. Based on the second and third connecting frames, the positions of the main wheel and the motor can be adjusted to accommodate sanding belts of different lengths.

[0014] Furthermore, a reinforcing plate is also provided on the second crossbeam. The reinforcing plate and the second arc-shaped connecting plate are located on the same plane and are integrally formed. One end of the reinforcing plate is coaxially connected to one end of the first arc-shaped connecting plate and is rotatably connected to the bottom of the vertical plate. Based on the reinforcing plate, the structural strength of the connection between the first and second crossbeams is improved.

[0015] Furthermore, the tension wheel is connected to a belt adjuster, which is located above the second crossbeam.

[0016] Furthermore, there are two of each of the first arc-shaped connecting plate, the second arc-shaped connecting plate, and the column. When there are two of each, the connection between the first and second crossbeams is more stable.

[0017] By adopting the above solution, the beneficial effects of this utility model are:

[0018] Based on the arc-shaped through groove of the second arc-shaped connecting plate and the first arc-shaped connecting plate, the second crossbeam rotates around the connection between the first arc-shaped connecting plate and the vertical plate as the center, realizing the overall rotation of components such as the main wheel, motor, second crossbeam, and sanding belt, so as to adjust the polishing angle to adapt to different materials to be polished and different types of sanding belts.

Detailed Implementation

[0023] 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.

[0024] Reference Figures 1 to 2 As shown, this utility model provides an adjustable belt grinder, the grinder comprising:

[0025] The frame includes a first crossbeam 1 and two columns 2 for fixing to the ground and supporting the first crossbeam 1. The first crossbeam 1 is provided with a first arc-shaped connecting plate 3 and a second arc-shaped connecting plate 4. The second arc-shaped connecting plate 4 has an arc-shaped through groove 41 inside.

[0026] The second crossbeam 5 is provided with a vertical plate 6. The bottom of the vertical plate 6 is rotatably connected to one end of the first arc-shaped connecting plate 3, and the top of the vertical plate 6 is rotatably connected to the second arc-shaped connecting plate 4. The connecting bolts of the vertical plate 6 and the second arc-shaped connecting plate 4 can slide along the arc-shaped through groove 41.

[0027] Main wheel 7 is located at one end of the second crossbeam 5;

[0028] Motor 8 is located at the other end of the second crossbeam 5. Its drive end is connected to the main wheel 7 via a sanding belt and covers the surface of the main wheel 7.

[0029] Tension wheel 9 is located above the second crossbeam 5 and between the motor 8 and the main wheel 7. It is used to adjust the tension of the sanding belt.

[0030] Workbench 10 is located at one end of the first crossbeam 1 and on one side of the main wheel 7.

[0031] The first crossbeam 1 is a square tube, and the worktable 10 is slidably mounted in the first connecting frame 11. The first connecting frame 11 is inserted into one end of the first crossbeam 1 and fixed with bolts. Based on the first connecting frame 11, the worktable 10 can move back and forth and up and down, which facilitates the adjustment of the grinding position.

[0032] The second crossbeam 5 is a square tube. The main wheel 7 is rotatably connected to the second connecting frame 12. The second connecting frame 12 is inserted into one end of the second crossbeam 5 and fixed with bolts. The motor 8 is connected to the third connecting frame 13, which is inserted into the other end of the second crossbeam 5 and fixed with bolts. Based on the second connecting frame 12 and the third connecting frame 13, the positions of the main wheel 7 and the motor 8 can be adjusted to accommodate sanding belts of different lengths.

[0033] A reinforcing plate 14 is also provided on the second crossbeam 5. The reinforcing plate 14 and the second arc-shaped connecting plate 4 are located on the same plane and are integrally formed. One end of the reinforcing plate 14 is coaxially connected to one end of the first arc-shaped connecting plate 3, and is rotatably connected to the bottom of the vertical plate 6. Based on the reinforcing plate 14, the connection structure strength between the first crossbeam 1 and the second crossbeam 5 is improved.

[0034] Tension pulley 9 is connected to a belt adjuster 15, which is connected above the second crossbeam 5.

[0035] There are two of each of the first arc-shaped connecting plate 3, the second arc-shaped connecting plate 4, and the column 2. When there are two of each of the first arc-shaped connecting plate 3, the second arc-shaped connecting plate 4, and the column 2, the connection between the first crossbeam 1 and the second crossbeam 5 is more stable.

[0036] Working principle: When adjusting the angle between the first crossbeam 1 and the second crossbeam 5, loosen the connecting bolts between the upright plate 6 and the first arc-shaped connecting plate 3 and the second arc-shaped connecting plate 4, and then rotate the second crossbeam 5. At this time, the second crossbeam 5 rotates around the connecting bolt at the bottom of the upright plate 6 (that is, it rotates along the coaxial connection between the reinforcing plate 14 and the first arc-shaped connecting plate 3). The connecting bolt at the top of the upright plate 6 slides in the arc-shaped through groove 41 of the second arc-shaped connecting plate 4, thus limiting the rotation angle of the second crossbeam 5.

[0037] During operation, the sanding belt is fitted onto the drive end of the motor 8, the tension wheel 9, and the main wheel 7. When the motor 8 rotates, it drives the sanding belt to rotate in a cycle, thus initiating the polishing and grinding work.

[0038] This utility model is based on the arc-shaped through groove 41 of the second arc-shaped connecting plate 4 and the first arc-shaped connecting plate 3, so that the second crossbeam 5 rotates with the connection between the first arc-shaped connecting plate 3 and the vertical plate 6 as the center, realizing the overall rotation of the main wheel 7, motor 8, second crossbeam 5, sanding belt and other components, so as to adjust the polishing angle to adapt to different materials to be polished and different types of sanding belts.

[0039] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
