Description

Technical Field

[0001] This utility model relates to the field of plate grinding technology, and in particular to a plate edge surface grinding mechanism. 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] Before vacuum infusion of pultruded sheets, grinding the edges of their upper and lower surfaces is a crucial step in ensuring product quality and appearance. However, most existing grinding equipment can only grind a single surface of the sheet, making it difficult to grind the edges of both surfaces simultaneously. This results in low processing efficiency, and repeated flipping operations can easily damage the sheet surface and cause positional shifts, affecting grinding accuracy. Furthermore, the structural design of existing grinding equipment does not adequately consider the collection and cleaning of grinding debris. A large amount of residual debris not only interferes with the grinding process and affects grinding quality but can also easily enter the equipment's interior, accelerating wear on components and shortening the equipment's lifespan. Therefore, a new edge grinding mechanism for sheet materials needs to be designed.

[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 grinding mechanism for the edge surface of a sheet material to solve the problems of existing equipment being difficult to grind simultaneously, having low efficiency, easily damaging the sheet, and insufficient debris collection and cleaning when grinding the upper and lower surface edges before vacuum injection of pultruded sheets.

[0006] This utility model embodiment adopts the following technical solution: a grinding mechanism for the edge surface of a board. It includes at least one grinding assembly, each assembly comprising a grinding component and a motor for driving the grinding component to rotate; a dust suction unit, fixedly installed at the end of the motor, with an opening on its side, the grinding component partially embedded inside the dust suction unit, and the remaining portion exposed through the opening; a limiting unit, installed on one side of the grinding component, supporting and limiting the side position of the board; and a dustproof part, installed on the limiting unit.

[0007] Furthermore, the bottom of the suction unit is connected to a first suction pipe that is set at an angle, and one end of the first suction pipe forms a negative pressure communication channel with the suction port of an external suction device.

[0008] Furthermore, the limiting unit integrates a support part and a limiting part.

[0009] Furthermore, the dustproof parts are arranged in two opposing groups, which are respectively assembled on the support part and the limiting part. The dustproof parts are long plate-shaped brush body structures.

[0010] Furthermore, the two sets of dustproof sections arranged opposite each other form a closed dustproof zone through brush bristles, with the brush bristle spacing being less than the thickness of the board.

[0011] Furthermore, the support portion has a fixing portion, and the fixing portion is connected to two sets of support members through a guide unit.

[0012] Furthermore, the fixing part has a through groove, and the grinding part passes through the groove and contacts the surface of the plate.

[0013] Furthermore, a second suction pipe is detachably installed on the side of the limiting part. The suction port of the second suction pipe faces the edge grinding area of ​​the board and forms a complementary suction layout with the first suction pipe.

[0014] The above-mentioned technical solutions adopted in the embodiments of this utility model can achieve the following beneficial effects:

[0015] Driven by a motor, the grinding component rotates at high speed. Combined with the precise positioning of the side opening of the dust collection unit, the edges of the board can be efficiently ground. The structure of the dust collection unit embedded in the grinding component can immediately cover the grinding area. Combined with the first dust collection pipe at the bottom, it forms a preliminary dust collection channel, effectively reducing dust overflow. The limiting unit is installed on one side of the grinding component. Its support and limiting parts form vertical constraints on the side of the board, ensuring the stability of the board position during grinding and avoiding processing errors caused by displacement. Two sets of oppositely arranged dustproof parts are installed on the limiting unit. Through the long plate-shaped brush body structure, they form an elastic contact with the surface of the board, creating a closed dustproof zone. During dynamic processing, it prevents dust from spreading to the surroundings, protecting the working environment and preventing dust from affecting the operating accuracy of the equipment.

[0025] 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.

[0026] The technical solutions provided by the various embodiments of this utility model are described in detail below with reference to the accompanying drawings.

[0027] Reference Figures 1 to 5 As shown, this utility model embodiment provides a grinding mechanism for the edge surface of a board, including at least one grinding assembly 2. The grinding assembly 2 includes a grinding component 212 and a motor 23 for driving the grinding component 212 to rotate; a dust suction part 24, which is fixedly installed at the end of the motor 23, with an opening on the side, the grinding component 212 is partially embedded in the dust suction part 24, and the remaining part is exposed through the opening; a limiting unit 29, which is installed on one side of the grinding component 212 to support and limit the side position of the board; and a dustproof part 210, which is installed on the limiting unit 29 to block the dust generated during the grinding operation.

[0028] In order to facilitate the centralized collection of dust, the bottom of the dust collection unit 24 is connected to an inclined first dust collection pipe 25. One end of the first dust collection pipe 25 forms a negative pressure communication channel with the suction port of the external dust collection device. The inclined first dust collection pipe 25 can use gravity to assist in the dust transportation.

[0029] In order to support and limit the board material, the limiting unit 29 integrates a support part 291 and a limiting part 292. The support part 291 is used to receive and support the edge area of ​​the board material, while the limiting part 292 forms a limiting constraint in the space above the edge of the board material.

[0030] Specifically, the dustproof part 210 is arranged in two sets opposite to each other. The two sets of dustproof parts 210 are respectively assembled on the support part 291 and the limiting part 292. The dustproof part 210 is a long plate-shaped brush body structure. By adapting the shape of the brush body to the spatial layout of the equipment, it can achieve dustproof coverage of the processing area.

[0031] It should be noted that the two sets of dustproof sections 210 arranged opposite each other form a closed dustproof zone through the bristles. The bristle spacing is smaller than the thickness of the board, ensuring that the upper and lower surfaces of the board make elastic contact with the bristles when the board passes through, effectively blocking the spread of dust during dynamic processing.

[0032] Specifically, the support part 291 has a fixing part 28, which is connected to two sets of support members 22 through a guide unit 27. The fixing part 28 can drive the support part 291 and a set of dustproof parts 210 to move synchronously, so as to adjust the distance between the limiting part 292 and the other set of dustproof parts 210. The fixing part 28 can drive the support part 291 and a set of dustproof parts 210 to move synchronously in the vertical direction along the guide unit 27, so as to realize the dynamic adjustment of the distance between the limiting part 292 and the second set of dustproof parts 210, so as to adapt to the processing requirements of plates of different thicknesses.

[0033] Specifically, the fixing part 28 is provided with a through groove 281. The grinding part 212 passes through the groove and contacts the surface of the plate. The size of the through groove 281 is adapted to the outer contour of the grinding part 212, which not only ensures the rotation space of the grinding part 212, but also forms a limiting guide for the grinding area of ​​the plate.

[0034] To prevent dust from flying upwards during sanding, a second suction pipe 211 is detachably installed on the side of the limiting part 292. The suction inlet of the second suction pipe 211 faces the sanding area at the edge of the board and forms a complementary suction layout with the first suction pipe 25. The second suction pipe 211 can directionally capture dust particles flying upwards during sanding, effectively preventing dust from accumulating between the limiting part 292 and the contact surface of the board, and avoiding adverse effects caused by dust accumulation.

[0035] During the grinding operation, the bottom of the board comes into contact with the support part 291 of the limiting unit 29, and the top is limited by the limiting part 292. At the same time, the bristles of the upper and lower dustproof parts 210 adhere to the surface of the board due to elastic deformation, forming a closed dustproof zone.

[0036] Motor 23 drives the grinding part 212 to rotate at high speed. Part of it passes through the through groove 281 of the fixed part 28 and contacts the edge of the plate for grinding. The grinding assembly 2 performs surface processing. Among the dust generated by grinding, the part that flies upward is efficiently sucked by the external negative pressure equipment with the help of the tangential dust suction channel because the suction inlet of the second dust suction pipe 211 is facing the grinding area and the tilt direction is consistent with the rotation direction of the grinding part 212. Large dust particles settle into the dust suction part 24 due to gravity and are guided by gravity through the first dust suction pipe 25 at the bottom with the assistance of gravity. The negative pressure channel formed with the external equipment continuously sucks in the dust, avoiding secondary dust.

[0037] 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. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the scope of the present utility model shall still fall within the scope of the present utility model.
