Description

Technical Field

[0001] The utility model belongs to the technical field of dust prevention of surface grinders, and particularly relates to a dust prevention structure for a surface grinder. Background Art

[0002] A surface grinder is a type of grinder that mainly uses a grinding wheel to rotate and grind workpieces to achieve the required flatness. During the processing and production of grinders, a large amount of dust will be generated. Some existing dust covers of grinders cover the upper part of the grinder as a whole during use, which has requirements for the size of the workpieces to be ground, restricting the use range of the device. Moreover, due to the large size of the dust cover, the dust extraction effect of the dust suction device at the top on the dust generated during the grinding process is not very ideal, which may consume more energy without achieving the best dust removal effect.

[0003] Chinese Patent Publication No. CN 220372835 U discloses a CT examination body position pad, including: a surface grinder body, the coordinated use of a dust prevention mechanism and a cleaning mechanism. When the surface grinder body processes workpieces and generates dust, the suction pipe installed at the input end of the dust removal fan will suck the dust through the suction hood installed above the surface grinder body through a support rod, and convey it to the dust removal box through the air supply pipe at the output end. When the dust enters the dust removal box and is discharged through the air outlet on the top surface, the coarse filter screen, fine filter screen and activated carbon filter screen will adsorb and filter the large, small and tiny dust particles carried in the gas. At the same time, the input end of the water pump will draw the water in the water tank through the liquid outlet pipe and convey the water to the spray pipe through the water delivery pipe at the output end, and spray it on the coarse filter screen, fine filter screen and activated carbon filter screen through the atomizing nozzle to clean the dust adsorbed on them.

[0004] However, the suction hood of the above device is fixed by being fixed on the surface grinder body. The suction hood with a fixed size may not be applicable to all sizes of workpieces, which means that workpieces exceeding the size of the dust cover cannot be ground on this grinder. The operator cannot adjust the dust cover according to different sizes of workpieces, which reduces the flexibility of the equipment. At the same time, the suction hood of the device is too large, resulting in the dust removal fan at the top being unable to efficiently suck the dust during the processing, unable to effectively capture all the dust, resulting in low dust removal efficiency, and a dust removal fan with a higher power is required to maintain sufficient suction, which will lead to higher energy consumption. Therefore, it is necessary to provide a dust prevention structure for a surface grinder to solve the above problems. Summary of the Utility Model

[0005] The technical content of the utility model is to provide a dust prevention structure for a surface grinder.

[0006] To solve the above problems, the present utility model provides a dust-proof structure for a surface grinder, including: a workbench for placing workpieces above the grinder body, an upper end of the grinder body is connected with a control device that can move up and down, and a grinding tool is fixed below the control device. A dust-proof mechanism is fixed on the grinding tool, and a sealing mechanism is arranged at the bottom of the dust-proof mechanism. An air suction fan is arranged above the control device, and a suction pipe is connected to the air suction fan. The other side of the suction pipe is connected to the dust-proof mechanism. An output end of the dust-proof mechanism is connected with a dust discharge pipe, and the other end of the dust discharge pipe is connected to a dust removal box.

[0007] As a further solution of the present utility model, the dust-proof mechanism includes limit blocks, sliders and a dust-proof cover. Two groups of the limit blocks are fixed on the left and right sides of the grinding tool.

[0008] As a further solution of the present utility model, the slider is of a T-shaped structure, and a T-shaped sliding groove matching with the slider is opened in the limit block.

[0009] As a further solution of the present utility model, an upper end of the dust-proof cover is movably clamped in the limit block through the slider. The dust-proof cover and the limit block form an embedded sliding connection through the slider. The dust-proof cover can move upward through the slider, which can prevent the dust-proof cover from blocking the work of the grinding tool.

[0010] As a further solution of the present utility model, both the suction pipe and the dust discharge pipe are made of bendable materials. The suction pipe is installed on the top of the dust-proof cover and is communicated with the inside of the dust-proof cover, which can suck the dust inside the dust-proof mechanism to reduce the diffusion of dust in the working environment.

[0011] As a further solution of the present utility model, the sealing mechanism includes a sealing ring, a mounting plate and a mounting cone. The sealing mechanism is made of materials with flexibility and wear resistance, which can form an effective seal between the dust-proof cover and the protected equipment and reduce the leakage of dust and particulate matter.

[0012] As a further solution of the present utility model, a top of the mounting cone is of a conical structure, and a radius of the top cone is larger than a radius of a bottom columnar structure. A groove corresponding to the lower columnar structure of the mounting cone is opened on the dust-proof cover. The conical part can be passed through the groove to achieve a fixing effect, and it is convenient for disassembly and installation.

[0013] As a further solution of the present utility model, the mounting cone is fixed on the mounting plate, and four groups of mounting plates are respectively fixed on four sides of the sealing ring.

[0014] In summary, the present utility model includes at least one of the following beneficial technical effects:

[0015] First, the present utility model discloses a dust-proof structure for a surface grinder. It is described that a dust-proof mechanism is installed on the grinding tool. Since the dust-proof cover is movably engaged with the limit block through a slider, when the grinding tool continuously descends, the dust-proof cover moves upward through the slider, which can prevent the dust-proof cover from blocking the operation of the grinding tool. By providing a dust-proof cover installed on the grinding tool, local dust-proofing is carried out on the grinding part of the grinding tool, enabling the suction pipe to be closer to the source of dust generation, thereby more effectively capturing dust, reducing the diffusion of dust in the working environment, and the local dust-proof cover is small in volume and has no limitation on the size of the workpiece being processed.

[0016] Second, the present utility model discloses a dust-proof structure for a surface grinder. It is described that a sealing mechanism is provided at the bottom of the dust-proof cover. The sealing ring can form an effective seal between the dust-proof cover and the grinding tool, reducing the leakage of dust and particulate matter. The effective seal can reduce the pollution of the working environment by harmful dust, protect the health of the operator, and at the same time meet higher environmental protection standards. The good sealing effect can improve the suction efficiency of the dust collection device, ensure that the dust generated by the grinder is effectively captured, thereby improving the overall equipment efficiency. Moreover, the design of installing a cone above the sealing ring is easy to replace and disassemble, which can greatly reduce the maintenance time and improve the overall working efficiency. When the sealing ring needs to be replaced, the simple disassembly and assembly design can reduce the dependence on professional tools or professionals, thereby reducing the maintenance cost. The good sealing effect can ensure that the grinding device will not reduce its performance due to dust leakage during operation, thus guaranteeing the grinding quality.

Specific embodiments

[0025] Please refer to Figures 1-6 . A dust-proof structure for a surface grinder, comprising: a workbench 2 for placing workpieces above the grinder body 1, a control device 3 that can move up and down is connected to the upper end of the grinder body 1, and a grinding tool 4 is fixed below the control device 3, a dust-proof mechanism 5 is fixed on the grinding tool 4, and a sealing mechanism 6 is arranged at the bottom of the dust-proof mechanism 5, a dust suction fan 7 is arranged above the control device 3, a dust suction pipe 8 is connected to the dust suction fan 7, the other side of the dust suction pipe 8 is connected to the dust-proof mechanism 5, the output end of the dust-proof mechanism 5 is connected to a dust discharge pipe 9, and the other end of the dust discharge pipe 9 is connected to a dust removal box 10.

[0026] Preferably, the dust-proof mechanism 5 includes a limit block 51, a slider 52 and a dust-proof cover 53. Two groups of limit blocks 51 are fixed on the left and right sides of the grinding tool 4. The slider 52 is of a T-shaped structure, and a T-shaped chute matching the slider 52 is provided in the limit block 51. The upper end of the dust-proof cover 53 is movably clamped in the limit block 51 through the slider 52. The dust-proof cover 53 and the limit block 51 form an embedded sliding connection through the slider 52. Both the dust suction pipe 8 and the dust discharge pipe 9 are made of bendable materials, and the dust suction pipe 8 is installed on the top of the dust-proof cover 53 and is communicated with the inside of the dust-proof cover 53. When the grinding tool 4 continuously descends, the dust-proof cover 53 moves upward through the slider 52, which can prevent the dust-proof cover 53 from blocking the work of the grinding tool 4. By providing a dust-proof cover 53 installed on the grinding tool 4, local dust-proofing is carried out on the grinding part of the grinding tool 4, so that the dust suction pipe 8 can be closer to the source of dust generation, thereby more effectively capturing the dust inside the dust-proof cover 53 and reducing the diffusion of dust in the working environment. Moreover, the volume of the dust-proof cover 53 is small, and there is no limit to the size of the processed workpiece.

[0027] Preferably, the sealing mechanism 6 includes a sealing ring 61, a mounting plate 62 and a mounting cone 63. The sealing mechanism 6 is made of materials with flexibility and wear resistance. The top of the mounting cone 63 is a conical structure, and the radius of the top cone is larger than the radius of the bottom columnar structure. A groove corresponding to the lower columnar structure of the mounting cone 63 is provided on the dust cover 53. The mounting cone 63 is fixed on the mounting plate 62, and the four groups of mounting plates 62 are respectively fixed on the four sides of the sealing ring 61. When in use, the sealing ring 61 is placed below the dust cover 53, so that the mounting plate 62 is inserted from the bottom of the dust cover 53 and fits against the inner wall of the dust cover 53, and the mounting cone 63 fixed on the mounting plate 62 is fixed on the dust cover 53 through the upper groove from the inside of the dust cover 53. The sealing ring 61 can form an effective seal between the dust cover 53 and the protected device, reducing the leakage of dust and particulate matter. When wear occurs or the sealing effect is not good, the mounting cone 63 can be pulled out from the dust cover 53 for disassembly, reducing the maintenance time and improving the overall working efficiency.

[0028] The working principle of a dust-proof structure for a surface grinder provided by the present utility model is as follows:

[0029] Ensure that all components of the grinder body 1, the control device 3, the grinding tool 4 and the dust suction fan 7 are installed and in good working condition. Check whether the connections of the dust suction fan 7, the dust suction pipe 8 and the dust discharge pipe 9 are firm to ensure that the pipes are not leaking or damaged.

[0030] Check whether the sealing ring 61 is intact to ensure that it can effectively seal the gap between the dust cover 53 and the grinder. Place the sealing ring 61 below the dust cover 53, so that the mounting plate 62 is inserted from the bottom of the dust cover 53 and fits against the inner wall of the dust cover 53, and the mounting cone 63 fixed on the mounting plate 62 is fixed on the dust cover 53 through the upper groove from the inside of the dust cover 53. The sealing ring 61 can form an effective seal between the dust cover 53 and the protected device, reducing the leakage of dust and particulate matter.

[0031] Select a suitable grinding tool 4 and grinding parameters according to the working requirements, and ensure that the workbench 2 is clean. Fix the workpiece on the workbench 2 of the grinder body 1, adjust the grinding tool 4 to an appropriate position and angle, and start the grinding work.

[0032] When the grinding tool 4 descends for grinding, the dust cover 53 moves upward through the slider 52, which can prevent the dust cover 53 from blocking the operation of the grinding tool 4. By providing the dust cover 53 installed on the grinding tool 4, local dust prevention is carried out on the grinding part of the grinding tool 4, so that the suction pipe 8 can be closer to the source of dust generation, thereby more effectively capturing the dust inside the dust cover 53 and reducing the diffusion of dust in the working environment. Ensure that the suction fan 7 is always turned on so that the suction pipe 8 can timely suck away the dust generated by grinding, and discharge the sucked dust into the dust removal box 10 through the dust discharge pipe 9. If it is found that the suction efficiency decreases, immediately check whether the suction fan 7 is blocked or worn. When the sealing ring 61 is worn or the sealing effect is not good, the installation cone 63 can be pulled out from the dust cover 53 for disassembly, and a new sealing mechanism 6 can be replaced to reduce the maintenance time and improve the overall working efficiency.

[0033] After completing the grinding task, wait for the grinding tool 4 to stop rotating completely, turn off the suction fan 7, disconnect the power supply, clean the residual dust on the workbench 2 and the grinding tool 4, and check whether the grinding tool 4 and the dust cover 53 are damaged. Replace or maintain them if necessary.

[0034] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present invention, or directly or indirectly applied. In other related technical fields, the scope of the present invention is defined by the appended claims and their equivalents, and is similarly included within the scope of the patent protection of the present invention.
