Description

Technical Field

[0001] This utility model belongs to the technical field of benchtop grinding machines, and particularly relates to a benchtop grinding machine. Background Technology

[0002] Benchtop grinding machines are commonly used to sharpen various cutting tools and knives. In addition to meeting some common requirements of grinding machine tools, grinding machines are characterized by high speed, simple structure, wide applicability, and generally manual operation. Grinding machines are frequently used in the manufacture of cutting tools and are generally not operated by fixed personnel.

[0003] However, during the use of bench grinders, the friction between the grinding wheel and the workpiece generates a large amount of debris. The debris generated during the grinding process mainly relies on natural falling or manual sweeping for collection and cleaning. This method is difficult to collect in a concentrated manner; manual sweeping is inefficient and increases the workload of operators; moreover, during the sweeping process, operators may inhale debris, which may cause harm to their health. Utility Model Content

[0004] In view of the shortcomings of the existing technology, this utility model provides a benchtop grinder, which solves the technical problems that existing benchtop grinders mainly rely on natural falling or manual sweeping to collect and clean the debris generated during the grinding process. These methods are difficult to collect in a concentrated manner; manual sweeping is inefficient and increases the workload of operators; moreover, operators may inhale debris during the sweeping process, which may cause harm to their health.

[0005] To achieve the above objectives, the main technical solutions adopted by this utility model include: A benchtop grinder includes a body, a powerful motor fixedly mounted on the top surface of the body, two waste inlets on the top surface of the body, and two grinding wheel covers connected to the top surface of the body through the two waste inlets. Drive shafts on both sides of the powerful motor pass through the grinding wheel covers and grinder blades are fixedly mounted thereon. A hopper is fixedly mounted on the top surface of the body, and the hopper is connected to the two grinding wheel covers through the two waste inlets. A rigid pipe is connected to the lower end of the hopper, and a semi-circular shell is connected to one side of the rigid pipe. A rotating shaft is rotatably mounted inside the semi-circular shell, and multiple fan blades are fixedly mounted on the rotating shaft. A waste bin is connected to the lower end of the rigid pipe.

[0006] Furthermore, the lower end of the rigid pipe is connected to the waste bin via a telescopic flexible tube. Multiple support plates are fixedly installed on the outer wall of the waste bin, and multiple support columns are fixedly installed on the bottom surface of the inner body of the machine. A spring is installed between the upper end of the support column and the bottom surface of the support plate. An upper copper block is fixedly installed on the bottom surface of the waste bin, and a lower copper block is fixedly installed on the inner bottom surface of the support plate below the upper copper block. An electric bell and a battery are installed on the side wall of the machine. The upper copper block is electrically connected to the electric bell via a first wire, the electric bell is electrically connected to the battery via a second wire, and the battery is electrically connected to the lower copper block via a third wire.

[0007] Furthermore, a servo motor is fixedly mounted on the surface of the semi-circular shell, and one end of the rotating shaft is fixedly connected to the drive shaft of the servo motor.

[0008] Furthermore, the side wall of the machine body is provided with several heat dissipation holes.

[0009] Furthermore, the waste bin is equipped with a breathable mesh on its side wall, which allows air to pass through while blocking waste from passing through.

[0010] Furthermore, multiple railings are fixedly installed inside the waste inlet.

[0011] Furthermore, the bottom surface of the machine body is provided with an opening, and the bottom surface of the waste bin is connected to a discharge pipe, which passes through the opening.

[0012] Furthermore, a valve is installed on the discharge pipe.

[0013] Furthermore, the bottom surface of the machine body is fixedly provided with multiple fixed legs.

[0014] The beneficial effects of this utility model are: 1. During the grinding process of the bench grinder, the waste chips generated can pass through the waste inlet into the hopper through the suction force generated by the fan blades. Then, the waste chips pass through the rigid pipe into the telescopic hose and then into the waste bin.

[0015] 2. As the weight of the scrap in the scrap bin gradually increases, the scrap bin will compress the spring and descend. The descent of the scrap bin will cause the upper copper block to descend as well. When the upper copper block descends and contacts the lower copper block, the electric bell will be energized and ring. This indicates that the scrap bin needs to be discharged. Open the valve, and the scrap will be discharged through the discharge pipe. After the scrap is discharged, the weight in the scrap bin will decrease and it will rise. The rise of the scrap bin will cause the upper copper block to rise and move away from the lower copper block. The electric bell will then be de-energized and the ringing will stop.

[0018] To better explain and facilitate understanding of this utility model, the present utility model will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0019] like Figure 1-3As shown, this utility model provides a benchtop grinder, including a body 1. A powerful motor 5 is fixedly mounted on the top surface of the body 1. Two waste inlets 12 are opened on the top surface of the body 1, and two grinding wheel covers 4 are connected to the top surface of the body 1 through the two waste inlets 12. The drive shafts on both sides of the powerful motor 5 pass through the grinding wheel covers 4 and grinding wheel discs 3 are fixedly mounted inside the grinding wheel covers 4. A hopper 26 is fixedly mounted on the top surface inside the body 1. The hopper 26 is connected to the two grinding wheel covers 4 through the two waste inlets 12. The lower end of the hopper 26 is connected to... A rigid pipe 25 is connected to a semi-circular shell 28 on one side. A rotating shaft 29 is rotatably mounted inside the semi-circular shell 28, and multiple fan blades 30 are fixed on the rotating shaft 29. The lower end of the rigid pipe 25 is connected to a waste bin 23. The lower end of the rigid pipe 25 is connected to the waste bin 23 through a telescopic hose 24. Multiple support plates 22 are fixed on the outer wall of the waste bin 23. Multiple support columns 19 are fixed on the bottom surface of the inner body 1. Springs 21 are installed between the upper end of the support columns 19 and the bottom surface of the support plates 22. An upper copper block 17 is fixedly mounted on the bottom surface of the waste bin 23. A lower copper block 16 is fixedly mounted on the inner bottom surface of the support plate 22, below the upper copper block 17. An electric bell 8 and a battery 13 are installed on the side wall of the machine body 1. The upper copper block 17 is electrically connected to the electric bell 8 through wire 1 7. The electric bell 8 is electrically connected to the battery 13 through wire 2 9. The battery 13 is electrically connected to the lower copper block 16 through wire 3 10. A servo motor 27 is fixedly mounted on the surface of the semi-circular shell 28. One end of the rotating shaft 29 is connected to the servo motor. 27. Drive shaft is fixedly connected; several heat dissipation holes 6 are opened on the side wall of the machine body 1; a breathable net 20 is installed on the side wall of the waste bin 23, which allows air to pass through and blocks waste from passing through; multiple railings 2 are fixedly installed inside the waste inlet 12; an opening 18 is opened on the bottom surface of the machine body 1, and a discharge pipe 14 is connected to the bottom surface of the waste bin 23, which passes through the opening 18; a valve 15 is installed on the discharge pipe 14; multiple fixed legs 11 are fixedly installed on the bottom surface of the machine body 1.

[0020] When in use, starting the servo motor 27 drives the rotating shaft 29 to rotate, which in turn drives the fan blade 30 to rotate. The rotation of the fan blade 30 generates suction. The waste chips generated during the grinding process of the bench grinder can pass through the waste inlet 12 into the hopper 26 through the suction generated by the fan blade 30. Then, the waste chips pass through the rigid pipe 25 into the telescopic flexible hose 24, and then through the telescopic flexible hose 24 into the waste bin 23. The ventilation net 20 allows air to pass through and blocks the waste chips.

[0021] As the weight of the scrap inside the scrap bin 23 gradually increases, the scrap bin 23 will compress the spring 21 and descend. The descent of the scrap bin 23 will cause the upper copper block 17 to descend. When the upper copper block 17 descends and comes into contact with the lower copper block 16, the electric bell 8 will be energized and ring. This indicates that the scrap bin 23 needs to be discharged. The valve 15 is opened, and the scrap is discharged through the discharge pipe 14. After the scrap is discharged, the weight inside the scrap bin 23 is reduced and it rises. The rise of the scrap bin 23 will cause the upper copper block 17 to rise and move away from the lower copper block 16. The electric bell 8 will be de-energized and the ringing will stop.
