Description

Technical Field

[0001] This utility model relates to the field of grinding machine technology, and in particular to a protective structure for a photovoltaic grinding machine. Background Technology

[0002] Grinding machines are machine tools that use abrasives to grind the surface of workpieces. Most grinding machines use high-speed rotating grinding wheels for grinding, while a few use other abrasives and free abrasives such as oilstones, belt abrasives, honing machines, ultra-precision machining tools, belt grinding machines, grinding machines, and polishing machines. When grinding workpieces, grinding machines generate a large amount of debris and dust.

[0003] Existing photovoltaic grinding machines cannot collect chips and dust when grinding workpieces. Chips are scattered and can easily cause injury to workers around the grinding machine. The dust generated is also polluting the air and can be inhaled by workers, causing health problems. In addition, dust can easily enter the machine tool components, reducing the machine tool's service life. Utility Model Content

[0013] 1. In this utility model, when a workpiece is being ground by a grinding machine, an absorption fan is simultaneously activated. The debris and dust generated during grinding are sucked into the first connecting cover through the first connecting pipe. The dust can pass through the filter plate, while the debris is intercepted and accumulated on the upper part of the filter plate. The debris generated during the processing is absorbed into the first connecting cover by the first connecting pipe through the filter plate. The debris accumulates in the space between the filter plate and the first connecting cover, preventing the debris from scattering and splashing, thus avoiding injury to the workers.

[0014] 2. In this utility model, water in the water tank is drawn into the water distribution tank through a water pipe. The water in the water distribution tank falls onto the upper part of the water curtain plate through the water distribution outlet. The water flows out from the water holes. Multiple sets of water holes are arranged side by side. The water flow from the water holes forms a water curtain. The water curtain absorbs the dust entering the dust removal box. The wastewater mixed with dust is discharged through the through holes. At the same time, the buffer component can buffer the dust gas and reduce the flow rate of the dust gas. The slower flow rate of the dust gas can be better absorbed by the water curtain, increasing the dust absorption rate and preventing a large amount of dust from being discharged into the air and causing air pollution. It also protects the health of the staff. Attached Figure Description

[0023] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0024] Example 1

[0025] Reference Figures 1-2 This is the first embodiment of the present invention, which provides a protective structure for a photovoltaic grinding machine, including a grinding machine 1, a grinding machine 2 at the upper end of the grinding machine 1, a first connecting pipe 3 on the outer wall of the grinding machine 2, an absorption component 4 connected to the end of the first connecting pipe 3 away from the grinding machine 2, the absorption component 4 including a first connecting cover 41 connected to the lower end of the first connecting pipe 3, a filter plate 42 at the lower end of the first connecting cover 41, an absorption fan 43 at the lower end of the filter plate 42, and a second connecting cover 44 at the lower end of the absorption fan 43.

[0026] Multiple sets of positioning rods 45 are fixedly provided on the outer wall of the second connecting cover 44, and multiple sets of positioning sleeves 46 are fixedly provided on the outer wall of the first connecting cover 41. The positioning rods 45 move sequentially from bottom to top through the absorption fan 43, the filter plate 42 and the positioning sleeves 46. The upper end of the outer wall of the positioning rods 45 is threaded with a threaded sleeve 47.

[0027] When the workpiece is being ground by the grinder 2, the absorption fan 43 is simultaneously activated. The debris and dust generated during grinding are sucked into the first connecting cover 41 through the first connecting pipe 3. The dust passes through the filter plate 42, while the debris is trapped and accumulates on the upper end of the filter plate 42. When it is necessary to clean the debris from the upper end of the filter plate 42, the threaded sleeve 47 can be unscrewed from the upper end of the positioning rod 45. Then, along the positioning rod 45, the first connecting cover 41, filter plate 42, and absorption fan 43 are slid upwards in sequence. The first connecting cover 41 and the filter plate 42 are separated, which makes it easy to clean the debris accumulated between the first connecting cover 41 and the filter plate 42. The staff can clean the absorption fan 43 to avoid excessive dust accumulation on the absorption fan 43, which would affect the intake and exhaust effect of the absorption fan 43. Through the filtration of the filter plate 42, the debris generated in the processing is absorbed into the first connecting cover 41 by the first connecting pipe 3. The debris accumulates in the space between the filter plate 42 and the first connecting cover 41, preventing the debris from scattering and splashing, which could cause injury to the staff.

[0028] Example 2

[0029] Reference Figure 1-6This is the second embodiment of the present invention. The difference between this embodiment and the first embodiment is that: the end of the second connecting rod 5 away from the second connecting cover 44 is connected to a buffer assembly 6. The buffer assembly 6 includes a buffer box 61 located at one end of the second connecting rod 5. A dust removal assembly 7 is located at one end of the outer wall of the buffer box 61. The dust removal assembly 7 includes a dust removal box 71 connected to one side of the buffer assembly 6. A water distribution box 72 is located at the upper end of the dust removal box 71. Multiple sets of water curtain plates 73 are located at the upper end of the inner cavity of the dust removal box 71. A water trough 74 is opened in the middle of the water curtain plate 73. Multiple sets of water holes 75 are opened at the lower end of the water curtain plate 73 located in the water trough 74.

[0030] The buffer assembly 6 also includes multiple sets of fixing blocks 62 located at the upper and lower ends of the inner wall of the buffer box 61. A slide rod 63 is fixedly provided at the middle of the fixing block 62, a slide sleeve 64 is movably sleeved on the outer wall of the slide rod 63, and a spring 65 is sleeved on the outer wall of the slide rod 63.

[0031] The inner wall of the buffer box 61 is hinged with multiple sets of parallel buffer plates 67. An adjusting rod 66 is provided between the buffer plate 67 and the sliding sleeve 64. The two ends of the adjusting rod 66 are respectively hinged to the buffer plate 67 and the sliding sleeve 64.

[0032] The water curtain plate 73 is tilted downwards at a certain angle from top to bottom. The bottom of the dust collector 71 is movably inserted with a base plate 76. The bottom of the base plate 76 has multiple sets of through holes 77. Four sets of bolts 79 are threaded into the four corners of the bottom of the base plate 76. The bottom of the dust collector 71 has threaded holes that cooperate with the bolts 79.

[0033] A water tank 8 is provided on one side of the dust collector 71. A water pipe 9 is connected to the bottom of the water tank 8 via a water pump. The end of the water pipe 9 away from the water pump is connected to the water distribution tank 72. A multi-group water inlet 78 is provided at the lower end of the water distribution tank 72 and the upper end of the dust collector 71.

[0034] A PLC controller 10 is fixedly installed on the outer wall of the grinding machine 1. The grinding machine 2, filter plate 42, and water pump are all electrically connected to the PLC controller 10.

[0035] The filtered dust enters the buffer box 61 through the second connecting rod 5, and then enters the dust collector 71. The PLC controller 10 starts the water pump, and water from the water tank 8 is drawn into the distribution tank 72 through the water pipe 9. The water in the distribution tank 72 falls onto the upper part of the water curtain plate 73 through the water outlet 78. Because the water curtain plate 73 is inclined downwards, the water flow at the upper part of the water curtain plate 73 slides along the water trough 74. When it passes through the water hole 75, it flows out from the water hole 75. Multiple sets of water holes 75 are arranged side by side, so the water flow discharged from the water hole 75 forms a water curtain. The dust and water curtain come into contact, forming water droplets that drip onto the upper part of the bottom plate 76. The wastewater mixed with dust is discharged through the through hole 77, which can be collected and treated by the staff. When the dust collector 71 needs to be cleaned, the bolt 79 can be unscrewed from the lower part of the bottom plate 76. The bolt 79 is unscrewed from the threaded hole at the bottom of the dust collector 71, allowing for the disassembly of the base plate 76 and the dust collector 71. This facilitates cleaning and maintenance of the dust collector 71. Before dust enters the dust collector 71, it enters the buffer box 61 and contacts the buffer plate 67, pushing the buffer plate 67 to rotate at a certain angle. The buffer plate 67 then drives the adjusting rod 66 to rotate at a certain angle. The adjusting rod 66 drives the sliding sleeve 64 to slide along the outer wall of the sliding rod 63 and compress the spring 65. Under the counter-elastic force of the spring 65, the dust gas is buffered, preventing the dust flow rate from entering the dust collector 71 too quickly and damaging the water curtain formed in the dust collector 71. Furthermore, the slower-flowing dust gas can be better absorbed by the water curtain, increasing the dust absorption rate and preventing a large amount of dust from being discharged into the air, causing air pollution, while also ensuring the health of the staff.

[0036] The remaining structure is the same as that in Example 1.

[0037] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
