Description

Technical Field

[0001] This utility model relates to the field of plate grinding technology, and in particular to plate edge grinding equipment. Background Technology

[0002] In the field of wind turbine blade manufacturing, pultrusion molding is a common technique for producing the main beam or auxiliary beam of wind turbine blades. Specifically, pultrusion is first used to produce pultruded sheets, which are then cut, ground, and processed to form components that meet standard dimensions. These components are then laid in the mold of the main beam or auxiliary beam, and finally, the assembled pultruded sheets are bonded and fixed using a vacuum infusion process, thereby completing the production of the main beam or auxiliary beam.

[0003] In wind turbine blade manufacturing, the pultrusion process produces sheet metal that requires grinding to meet assembly requirements. However, existing sheet edge grinding equipment faces significant technical bottlenecks. Firstly, pultruded sheets are mostly made of composite materials such as glass fiber and carbon fiber. The dust generated during grinding is highly adhesive and irritating. Existing equipment has a simple dust collection and containment structure, making it difficult to create a sealed environment. This allows dust to easily spread throughout the workshop, harming worker health, contaminating equipment, and potentially affecting the bonding quality of subsequent vacuum infusion processes. Therefore, it is necessary to design new sheet edge grinding equipment.

[0004] It should be noted that the information disclosed in this background section is only for understanding the background technology of this application concept, and therefore may include information that does not constitute prior art. Utility Model Content

[0005] This utility model provides a plate edge grinding device to solve the problems of existing equipment being difficult to grind simultaneously, having low efficiency, easily damaging the plate, and insufficient debris collection and cleaning when grinding the upper and lower surface edges of pultruded plates before vacuum injection.

[0006] This utility model embodiment adopts the following technical solution: a plate edge grinding device. It includes at least one surface grinding device and one side grinding device. The surface grinding device includes at least one surface grinding mechanism; the side grinding device includes at least one side grinding mechanism, the surface grinding mechanism including a first grinding wheel and a first driving motor; a dust collection part, detachably mounted to the end of the first motor; a dust blocking part, disposed on the side of the first grinding wheel, for blocking grinding dust; the side grinding assembly includes a second grinding wheel and a second driving motor; and a dust collection part, detachably mounted to the end of the second motor, for dust collection.

[0007] Furthermore, a rectangular dust suction port is provided on the end side of the dust collection unit.

[0008] Furthermore, one side of the grinding wheel is provided with upper and lower support parts for supporting the bottom of the plate and limiting its upper position.

[0009] Furthermore, the upper and lower support portions include a limiting portion and a supporting portion.

[0010] Furthermore, the vertical support surface of the support part is provided with a mounting plate, and the mounting plate connects two sets of base plates through a sliding unit to form a linearly sliding connection pair.

[0011] Furthermore, the dust-blocking part is provided in two sets and is arranged opposite to each other. The two sets of oppositely arranged dust-blocking parts are detachably installed on the limiting part and the supporting part, respectively.

[0012] Furthermore, the mounting plate has a rectangular through slot for the grinding wheel to pass through.

[0013] Furthermore, the edge of the suction port is tightly attached to the side of the mounting plate by a sealing strip, forming a relatively closed dust collection chamber.

[0014] Furthermore, the dust collection unit includes a dust collection cylinder, a cover plate, a dust discharge pipe, and a dust collection box.

[0015] The above-mentioned technical solutions adopted in the embodiments of this utility model can achieve the following beneficial effects:

[0016] By designing surface and side grinding mechanisms, along with detachable dust collection, dust trapping, and dust blocking sections, efficient dust control and improved grinding quality are achieved. Specifically, the dust collection section of the surface grinding mechanism is detachably mounted at one end of the motor, forming a dust protection system with blocking and collection functions in conjunction with the side dust blocking section. This effectively intercepts dust splashed during the operation of the grinding wheel. Meanwhile, the dust trapping section of the side grinding component is detachably installed at the other end of the motor, working together with the surface dust collection section to create a two-stage dust collection system, improving dust capture efficiency and reducing workshop pollution.

[0029] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.

[0030] The technical solutions provided by the various embodiments of this utility model are described in detail below with reference to the accompanying drawings.

[0031] Reference Figures 1 to 8As shown, this utility model embodiment provides a plate edge grinding device, including at least a surface grinding device 1 and a side grinding device 2. The surface grinding device 1 includes at least a surface grinding mechanism 10; the side grinding device 2 includes at least a side grinding mechanism 20. The surface grinding mechanism 10 includes a grinding wheel 11 and a motor 12 for driving the grinding wheel 11; a dust collection part 13, which is detachably installed at the end of the motor 12; a dust blocking part 15, which is disposed on one side of the grinding wheel 11 for blocking grinding dust; the side grinding mechanism 20 includes a grinding wheel 21 and a motor 22 for driving the grinding wheel 21; and a dust collection part 23, which is detachably installed at the end of the motor 22 for collecting dust generated during the grinding process.

[0032] Since both the upper and lower edges of the board surface need to be sanded, the surface sanding equipment 1 is equipped with two sets: a lower surface sanding equipment and an upper surface sanding equipment (see reference). Figure 1 (From left to right).

[0033] Both the lower surface grinding equipment and the upper surface grinding equipment include two sets of surface grinding mechanisms 10, which are arranged in a centrally symmetrical manner.

[0034] In order to support the two sides of the board, the grinding wheel 11 is provided with upper and lower support parts 14 on one side for supporting the bottom and limiting the top of the board.

[0035] To accommodate the edges of plates of different thicknesses for support, the upper and lower support parts 14 include a limiting part 141 and a supporting part 142. The vertical support surface of the supporting part 142 is provided with a mounting plate 17. The mounting plate 17 is connected to two sets of base plates 111 through a sliding unit 16 to form a linearly sliding connection pair. The motor 12 is rigidly mounted on the top side of the two sets of base plates 111 in a straddle clamping manner. The limiting part 141 is connected to the two sets of base plates 111 and achieves limitation by contacting the plate. Ultimately, the upper and lower support parts 14 form a cooperative operation in which the supporting part 142 carries the drive and the sliding base, and the limiting part 141 constrains the position of the workpiece.

[0036] Specifically, a cylinder 18 is connected to the mounting plate 17, and its piston rod end is rigidly connected to the support part 142. When the cylinder 18 is activated, the piston rod extends and retracts, causing the support part 142 to move linearly back and forth along the vertical guide rail of the sliding unit 16, thereby realizing the dynamic adjustment of the distance between the support part 142 and the limiting part 141.

[0037] To ensure that dust is effectively contained and does not leak during the polishing process, the dust-blocking part 15 is a flat brush structure with a double-set opposing layout. The two sets of dust-blocking parts 15 are detachably installed on the limiting part 141 and the supporting part 142, respectively. The layout is adapted to allow the plate to pass through between the two sets of dust-blocking parts 15. The bristles of the flat brush can contact the surface of the plate, thereby enclosing and forming a barrier space, further blocking the dust from spreading and improving the dust containment effect.

[0038] To collect grinding dust and isolate the work area from dust, a rectangular suction port is provided on the front end of the dust collection unit 13 on the side corresponding to the feeding direction of the material. The edge of the suction port is tightly fitted to the side of the mounting plate 17 with a sealing strip, forming a relatively closed dust collection chamber. Three-quarters of the circumferential area of ​​the wheel body is located within the closed chamber of the dust collection unit 13, and a small portion of the wheel rim protrudes outward through the rectangular suction port to contact the material and perform the grinding action. A rectangular through groove is provided on the mounting plate 17 for the grinding wheel 11 to pass through (see reference). Figure 3 ).

[0039] A dust collection pipe 131 is connected to the dust collection section 13 to extract the dust in the dust collection section 13. A suction pipe 113 is fixedly installed on the side of the limiting section 141 at an angle, with its opening facing the grinding area. Both the suction pipe 113 and the dust extraction pipe 131 form a negative pressure passage through the connection with an external vacuum cleaner. When the external vacuum cleaner is started, the suction pipe 113 first captures the suspended dust in the grinding area, and the dust extraction pipe 131 simultaneously extracts the dust deposited in the dust collection section 13. The two pipes work together to achieve efficient dust removal and prevent dust leakage.

[0040] To collect grinding dust and isolate dust in the work area, the dust collection unit 23 includes a dust collection cylinder 231, a cover plate 232, a dust discharge pipe 233, and a dust collection box 234. The dust collection cylinder 231 is fixedly installed on the end face of the motor 22. The bottom of the dust collection cylinder 231 is notched. The dust collection box 234 is connected directly below the notch at the bottom of the dust collection cylinder 231. The grinding wheel 21 is placed inside the dust collection cylinder 231. The cover plate 232 is detachably installed at the opening of the dust collection cylinder 231. A dust baffle 210 is detachably installed on the cover plate 232. The dust collection cylinder 231 is in a state of wrapping the grinding wheel 21. The cover plate 232 closes the opening, and the dust baffle 210 blocks the edge gaps, forming a semi-enclosed space.

[0041] The side wall of the dust collection cylinder 231 is inclined and connected to the first dust discharge pipe 233, and the side wall of the dust collection box 234 is inclined and connected to the second dust discharge pipe 241. The other end of both dust discharge pipes is connected to an external vacuum cleaner. When the vacuum cleaner is working, the first dust discharge pipe 233 and the second dust discharge pipe 241 form a negative pressure passage. The former draws out the suspended dust in the dust collection cylinder 231, and the latter discharges the settled dust in the dust collection box 234. Together with the dust baffle brush 210 to block the dust, it achieves the dual functions of dust collection and sealing of the work area.

[0042] Specifically, the dust collection box 234 has an L-shaped design, and a support strip 25 is fixedly installed on the receiving plate 28. Its horizontal bottom surface is closely attached to the upper surface of the horizontal end of the dust collection box 234. In addition, there is a small gap between the top of the support strip 25 and the end of the bristles of the dust broom 210, which avoids friction and wear between the two and effectively prevents dust from overflowing.

[0043] To achieve precise adjustment of the distance between the second grinding wheel 21 and the side edge of the material, the second motor 22 is connected to a horizontal plate 29 via a fine-tuning unit 26. The fine-tuning unit 26 includes a measuring part 261 and two sets of guide parts 262. The bottom of the second motor 22 slides along the track between the two guide parts 262. The measuring part 261 is a digital dial indicator, and the sensing probe of the measuring part 261 is in contact with the end face of the second motor 22. When the second motor 22 is driven by the driving component to generate horizontal displacement along the guide parts 262, the sensing probe converts the displacement into a digital signal in real time and displays it. The operator can then precisely control the distance between the second grinding wheel 21 and the material to ensure processing accuracy.

[0044] Specifically, the horizontal plate 29 is connected to the receiving plate 28 via the displacement unit 27. The displacement unit 27 includes a slide rail 271 and a second cylinder 272. The second cylinder 272 is fixed on the receiving plate 28, and its telescopic end is connected to the horizontal plate 29. When the piston rod of the second cylinder 272 extends, it pushes the horizontal plate 29 to move away from the receiving plate 28 along the slide rail 271. Conversely, when air enters the rod chamber, the piston rod retracts, driving the horizontal plate 29 to move closer to the receiving plate 28. During the entire displacement process, the distance between the two sets of side grinding mechanisms 20 can be adjusted.

[0045] When sanding the surface of a board, it is generally done by two sets of centrally symmetrical sanding mechanisms combined to form a sanding channel in the middle, which work together to sand the surface and sides of the board.

[0046] In order to achieve simultaneous grinding of both sides of the edge of the board, the side grinding equipment 2 includes two sets of side grinding mechanisms 20, which are arranged symmetrically and staggeredly.

[0047] Specifically, the surface polishing mechanism 10 is equipped with an adjustment unit 19 at the bottom. The adjustment unit 19 includes a limiting unit 112, a turntable 191 and a lead screw 192. The turntable 191 drives the lead screw 192 to rotate. Under the action of the limiting unit 112, the surface polishing mechanism 10 and the side polishing mechanism 20 can move left and right.

[0048] Specifically, the grinding mechanism can be installed in two ways: one side is fixedly installed and the other side is slidably installed via the adjusting unit 19; or both sides can be slidably installed.

[0049] Specifically, the lower surface grinding equipment has a grinding wheel 11 of the surface grinding mechanism 10 located below the board. During grinding, a grinding channel is formed between the two sets of surface grinding mechanisms 10. The two sets of grinding wheels 11 grind the two sides of the lower surface of the board. The support part 142 supports the bottom edge of the board, while the limiting part 141 is located above the board and presses the board to ensure the stability of the board movement during the grinding process and avoid tilting.

[0050] A grinding channel is formed between the two sets of side grinding mechanisms 20. The support bar 25 supports the board. During grinding, the board enters the grinding channel and moves on the two sets of support bars 25, thereby using the two sets of grinding wheels 21 on both sides of the board to grind its sides.

[0051] The surface grinding equipment has a surface grinding mechanism 10 with a grinding wheel 11 located above the board. During grinding, a grinding channel is formed between the two sets of surface grinding mechanisms 10. The grinding wheel 11 grinds the two sides of the upper surface of the board. The limiting part 141 presses down on the board, and the supporting part 142 supports the bottom edge of the board. The limiting part 141 is located above the board and presses down on the board to ensure the stability of the board movement during the grinding process and avoid tilting.

[0052] In this embodiment, starting from the feeding side, the surface grinding mechanism 10 of the lower surface grinding equipment, the surface grinding mechanism 10 of the upper surface grinding equipment, and the side grinding mechanism 20 are sequentially arranged to sequentially complete the grinding of the two edges of the lower surface of the board, the two edges of the upper surface of the board, and the two sides of the board (see reference). Figure 1 (From left to right).

[0053] In order to ensure the smooth movement of the plate during the grinding process, the surface grinding mechanism 10 of the lower surface grinding equipment, the surface grinding mechanism 10 of the upper surface grinding equipment, and the side grinding mechanism 20 are all equipped with conveying mechanisms 4 on the feeding side and the discharging side. The conveying mechanism 4 includes rollers 43 that can move up and down, and a rolling part 44 located below the rollers 43.

[0054] Specifically, the conveying mechanism 4 also includes a fixed frame 41, on which a cylinder 42 is mounted. The lower end of the piston rod of the cylinder 42 is connected to the roller 43, and the rolling part 44 is located below the roller 43. During grinding, the plate passes between the roller 43 and the rolling part 44, and the up and down movement of the roller 43 can adapt to the conveying of plates of different thicknesses.

[0055] During the grinding operation, the sheet material is fed into the grinding equipment between the feed roller 43 and the rolling part 44, and can be moved towards the discharge side by a traction mechanism. The sheet material first passes between the limiting part 141 and the supporting part 142 of the surface grinding mechanism 10 in the lower surface grinding equipment, and the two sides of the lower surface of the sheet material are ground by two sets of grinding wheels 11; then the sheet material passes between the limiting part 141 and the supporting part 142 of the surface grinding mechanism 10 in the upper surface grinding equipment, and the upper surface of the sheet material is ground by two sets of grinding wheels 11; then it passes through the grinding channel between the side grinding mechanisms 20, and the sides of the sheet material are ground by grinding wheels 21; after the three-step grinding is completed, the sheet material can be removed from between the discharge roller 43 and the rolling part 44.

[0056] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model.
