[0033] Through the coordinated use of the base 1, the frame 2, the grinding mechanism 200 and the dust reduction component 300, during actual use, the tension of the sanding belt can be effectively adjusted according to the situation, thereby effectively avoiding the occurrence of the sanding belt being too loose and causing the sanding belt to deviate, and ensuring that the sanding belt is under appropriate tension can also improve the quality of grinding and reduce the wear and failure rate of the sanding belt. At the same time, dust reduction can also be performed, thereby effectively avoiding the dust generated by grinding from being raised in the air, thereby improving the practicality of the grinding device.

[0034] The grinding mechanism 200 in this embodiment is a structure for effectively grinding castings.

[0035] like Figure 1 and Figure 2 As shown, the grinding mechanism 200 includes a grinding component 201 installed on the top of the base 1 for grinding, and an adjusting component 202 installed on the top of the base 1 for adjusting the tension of the sanding belt.

[0036] It should be noted that a through hole is opened on the front of the protective mesh plate 3, and the bottom of the protective mesh plate 3 is fixed to the top of the base 1 to achieve a protective effect.

[0037] In this embodiment, the grinding assembly 201 is a structure for grinding castings.

[0038] like Figure 1 and Figure 2 As shown, the grinding assembly 201 includes a fixed block 2011 fixed to the top of the base 1, two motors 2012 fixed inside the fixed block 2011, a transmission rod 2013 fixed to the output shaft of the motor 2012, two polishing wheels 2014 respectively fixed to the opposite ends of the two transmission rods 2013, and a sanding belt body 2015 sleeved on the outside of the polishing wheel 2014.

[0039] In this embodiment, the adjustment component 202 is a structure for adjusting the tension of the sanding belt.

[0040] like Figure 1 and Figure 2 As shown, the adjustment component 202 includes two fixed cylinders 2021 respectively fixed on the left and right sides of the fixed block 2011, a screw 2022 rotatably connected to the inside of the fixed cylinder 2021, an adjusting wheel 2023 fixed to the bottom end of the screw 2022, an adjusting cylinder 2024 threadedly connected to the outside of the screw 2022, two sliders 2027 respectively fixed on the left and right sides of the adjusting cylinder 2024, a fixed seat 2028 fixed to the side of the adjusting cylinder 2024 away from the screw 2022, a connecting column 2029 fixed to the back of the fixing seat 2028, a mounting seat 20210 fixed to the end of the connecting column 2029 away from the fixing seat 2028, and a driven wheel 20211 rotatably connected to the inside of the mounting seat 20210 through a bearing.

[0041] It should be noted that an adjustment groove 2025 is provided on a side of the fixing cylinder 2021 away from the adjustment wheel 2023 , and the adjustment cylinder 2024 is slidably connected inside the adjustment groove 2025 to ensure that the adjustment cylinder 2024 can slide stably in the adjustment groove 2025 .

[0042] In addition, two sliding cavities 2027 are provided inside the fixed cylinder 2021 , and opposite sides of the two sliding cavities 2027 are respectively connected to the left and right sides of the adjustment groove 2025 , and the slider 2026 is slidably connected in the sliding cavity 2027 to ensure that the fixed cylinder 2021 can be limited by the slider 2027 .

[0043] In addition, the adjustable distance of the slider 2026 in the slide cavity 2027 is smaller than the adjustable distance of the screw rod 2022 in the adjustment tube 2024 , which can effectively prevent the screw rod 202 and the adjustment tube 2024 from falling off.

[0044] At the same time, the sanding belt body 2015 is sleeved between the outer sides of the driven wheel 20211 and the polishing wheel 2014 .

[0046] like Figure 1 , Figure 2 and Figure 3As shown, the dust reduction assembly 300 includes two bottom plates 301 fixed on the top of the base 1, a first vertical plate 302 fixed on the top of the bottom plate 301, a second vertical plate 303 fixed on the top of the bottom plate 301, two trapezoidal plates 304 fixed between the first vertical plate 302 and the second vertical plate 303 on opposite sides, an inclined plate 305 fixed on the front of the second vertical plate 303, a horizontal plate 306 fixed on the front of the second vertical plate 303, a water pump 307 fixed on the top of the horizontal plate 306, a water inlet pipe 308 fixed to the water inlet end of the water pump 307, a water outlet pipe 309 fixed to the water outlet end of the water pump 307, a buffer pipe 310 fixed to the side of the water outlet pipe 309 away from the water pump 307, and three drainage pipes 311 fixed to the front of the buffer pipe 310.

[0047] It should be noted that the front side of the drain pipe 311 passes through the second vertical plate 303 and extends to the front side of the second vertical plate 303, ensuring that the drain pipe 311 can transport water to the inclined plate 305, and the bottom side of the water inlet pipe 308 passes through the horizontal plate 306 and extends to the bottom side of the horizontal plate 306, ensuring that the water inlet pipe 308 can transport water on the bottom plate 301 to the water pump 307.

[0048] In addition, the left and right sides of the inclined plate 305 are respectively fixed to the opposite sides of the two corresponding trapezoidal plates 304, and the bottom of the inclined plate 305 is fixed to the top of the horizontal plate 306, so that the inclined plate 305 is effectively fixed.

[0049] The working principle of the above embodiment is:

[0050] When in use, the motor 2012 is turned on, and the polishing wheel 2014 is driven to rotate through the transmission rod 2013, so that the sanding belt body 2015 is driven to rotate through the cooperation of the polishing wheel 2014 and the driven wheel 20211, so that the staff can grind the casting through the sanding belt body 2015. When the tightness of the sanding belt body 2015 needs to be adjusted, the adjusting wheel 2023 is rotated to drive the screw rod 2022 to rotate, and the adjusting cylinder 2024 is moved up and down on the outside of the screw rod 2022 under the action of the internal thread rotation thrust and the limit of the slider 2026, so that the fixing seat 2028, the connecting rod 2026 and the fixing seat 2028 can be adjusted. The connecting column 2029 and the mounting seat 20210 are adjusted to move up and down, thereby driving the driven wheel 20211 to move up and down, thereby adjusting the distance between the driven wheel 20211 and the polishing wheel 2014, thereby adjusting the tension of the sanding belt body 2015. Then, during use, turn on the water pump 307, and transport the water on the top of the bottom plate 301 to the buffer pipe 310 through the water inlet pipe 308 and the water outlet pipe 309, and then spray the water onto the inclined plate 305 through the drain pipe 311, so that the water remains on the inclined plate 305, so as to deal with the dust generated by the grinding of the casting and achieve the purpose of dust reduction.

[0051] Compared with the prior art, the grinding device, through the coordinated use of the base 1, the frame 2, the grinding mechanism 200 and the dust reduction component 300, can effectively adjust the tension of the sanding belt according to the situation during actual use, thereby effectively avoiding the occurrence of the sanding belt being too loose and causing the sanding belt to deviate, and ensuring that the sanding belt is under appropriate tension can also improve the quality of grinding and reduce the wear and failure rate of the sanding belt. At the same time, dust reduction can also be performed, thereby effectively avoiding the dust generated by grinding from being raised in the air, thereby improving the practicability of the grinding device and solving the problem of low practicability of the existing grinding device.

The control circuit of the controller can be realized by simple programming by technicians in this field. The provision of an external power supply is also common knowledge in this field.
