Abstract
Description
Technical Field
[0001] This utility model relates to the field of pultruded profile technology, and in particular to an automatic grinding device for pultruded profiles. Background Technology
[0002] After pultruded profiles are formed, they need to be surface-polished to remove release agent and smooth surface defects, so as to meet the requirements of subsequent processing or use.
[0003] In existing grinding equipment, the mechanism used to transport profiles often suffers from insufficient clamping or driving stability, leading to axial offset or radial swaying of the profiles when entering and exiting the grinding area. This directly affects the adhesion accuracy between the grinding parts and the profile surface, further exacerbating the problem of localized missed or over-grinding, resulting in unstable grinding quality. Moreover, due to the lack of an effective enclosed dustproof structure, grinding debris and dust spread into the working environment during the profile transport process, polluting the air and affecting the final product quality as dust adheres to the surfaces of un-ground or ground profiles. Furthermore, the lack of guiding components during debris recovery prevents the effective collection of a large amount of scattered debris, with some debris even accumulating inside the device. This increases subsequent cleaning costs and may also exacerbate equipment wear as debris gets caught in the conveying or grinding mechanism.
[0004] Therefore, there is an urgent need for an automatic grinding device for pultruded profiles to solve the above-mentioned technical problems. Utility Model Content

[0021] The beneficial effects of this utility model are:
[0022] This invention provides an automatic grinding device for pultruded profiles, comprising a dustproof box, a conveying mechanism, a grinding mechanism, and a debris handling mechanism. The dustproof box confines the grinding operation within a closed space, reducing the diffusion of dust and debris generated during grinding to the outside environment, thus preventing pollution of the working environment and harm to the health of operators. The conveying mechanism includes a traction component for moving the profile in and out of the dustproof box, ensuring stable positioning of the profile during entry, exit, and grinding. The grinding mechanism, located inside the dustproof box, includes a grinding component and a position adjustment component. The position adjustment component allows adjustment of the relative position between the grinding component and the profile, thereby improving adaptability to different profiles and the grinding effect. The grinding component has a grinding part that conforms to the outer surface of the profile. When the profile passes through the dustproof box, the grinding part grinds the surface of the profile. The contact between the grinding part and the profile surface ensures uniform grinding, avoiding missed areas or uneven grinding. The debris handling mechanism includes a recovery funnel and a chip guide plate. The recovery funnel is located below the dust box and is used to collect debris generated after profile grinding. The inlet end of the recovery funnel is equipped with a chip guide plate circumferentially to form a comprehensive debris guiding area. One end of the chip guide plate extends to the bottom of the workpiece being ground, and the other end is connected to the recovery funnel, which can directly receive the debris generated during profile grinding and guide the debris into the recovery funnel. With the above configuration, the automatic pultruded profile grinding device of this application can improve the grinding quality of the profile and reduce debris diffusion.

[0031] After pultruded profiles are formed, they need to be surface-polished to remove release agent and smooth surface defects, so as to meet the requirements of subsequent processing or use.
[0032] In existing grinding equipment, the mechanism used to transport profiles often suffers from insufficient clamping or driving stability, leading to axial offset or radial swaying of the profiles when entering and exiting the grinding area. This directly affects the adhesion accuracy between the grinding parts and the profile surface, further exacerbating the problem of localized missed or over-grinding, resulting in unstable grinding quality. Moreover, due to the lack of an effective enclosed dustproof structure, grinding debris and dust spread into the working environment during the profile transport process, polluting the air and affecting the final product quality as dust adheres to the surfaces of un-ground or ground profiles. Furthermore, the lack of guiding components during debris recovery prevents the effective collection of a large amount of scattered debris, with some debris even accumulating inside the device. This increases subsequent cleaning costs and may also exacerbate equipment wear as debris gets caught in the conveying or grinding mechanism.
[0033] Therefore, there is an urgent need for an automatic grinding device for pultruded profiles to solve the above-mentioned technical problems.
[0034] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.
[0035] like Figure 1 and Figure 2 As shown, this embodiment provides an automatic grinding device for pultruded profiles, which includes a dustproof box 1, a conveying mechanism 2, a grinding mechanism 3, and a debris handling mechanism 4. The conveying mechanism 2 includes a traction component for driving the profile 100 in and out of the dustproof box 1. The grinding mechanism 3 is disposed inside the dustproof box 1 and includes a grinding component 31 and a position adjusting component 32 for adjusting the relative position of the grinding component 31 and the profile 100. The grinding component 31 is provided with a grinding part 311 that conformally fits the outer surface of the profile 100. When the profile 100 is conveyed through the dustproof box 1, the grinding part 311 grinds the surface of the profile 100. The debris handling mechanism 4 includes a recovery funnel 41 and a chip guide plate 42. The recovery funnel 41 is disposed below the dustproof box 1 and is used to collect the debris generated after the profile 100 is ground. The inlet end of the recovery funnel 41 is provided with a chip guide plate 42 around its circumference. One end of the chip guide plate 42 extends to the bottom of the grinding component 31, and the other end is connected to the recovery funnel 41.
[0036] In this embodiment, the dust box 1 confines the grinding operation within a closed space, reducing the diffusion of dust and debris generated during grinding to the outside environment and preventing pollution of the working environment and harm to the health of operators. The conveying mechanism 2 includes a traction component for driving the profile 100 in and out of the dust box 1, ensuring the stable position of the profile 100 during entry, exit, and grinding. The grinding mechanism 3 is disposed inside the dust box 1 and includes a grinding component 31 and a position adjustment component 32. The position adjustment component 32 can adjust the relative position between the grinding component 31 and the profile 100, thereby improving the adaptability to different profiles 100 and the grinding effect. The grinding component 31 has a grinding part 311 that conforms to the outer surface of the profile 100. When the profile 100 is conveyed through the dust box 1, the grinding part 311 grinds the surface of the profile 100. By adhering to the surface of the profile 100, the grinding part 311 uniformly grinds the surface of the profile 100, avoiding localized missed areas or uneven grinding. The debris handling mechanism 4 includes a recovery funnel 41 and a chip guide plate 42. The recovery funnel 41 is located below the dust box 1 and is used to collect the debris generated after the profile 100 is ground. The chip guide plate 42 is circumferentially arranged at the inlet end of the recovery funnel 41 to form an all-round debris guiding area. One end of the chip guide plate 42 extends to the bottom of the grinding part 31, and the other end is connected to the recovery funnel 41, which can directly receive the debris generated by the grinding of the profile 100 and guide the debris into the recovery funnel 41. With the above configuration, the automatic grinding device for pultruded profiles in this embodiment can improve the grinding quality of the profile 100 and reduce debris diffusion.
[0037] It should be noted that the traction component in this embodiment can adopt a chain traction mechanism, a belt clamping mechanism, etc., to stably drive the profile 100 to move along a preset path. No specific limitations are placed on the specific structure of the traction component, as long as it can achieve the above-mentioned functions.
[0038] The specific structure of the automatic grinding device for pultruded profiles is described below:
[0039] Specifically, such as Figure 1 and Figure 2 As shown, the conveying mechanism 2 also includes multiple rotating and spaced-apart support wheels. The outer peripheral walls of the support wheels are configured to abut against the surface of the profile 100, thereby providing auxiliary support from below or to the side of the profile 100 and improving the stability of the profile 100 during conveying. The support wheels can be made of rubber, metal, or other materials, which can provide auxiliary support for the profile 100 and reduce conveying friction. The specific structure of these components is not limited here, as long as they achieve the aforementioned functions.
[0040] Specifically, the grinding component 31 includes two grinding blocks 312. Each grinding block 312 has a concave surface on its inner side, which is close to each other. The two concave surfaces enclose a grinding space 313 for the profile 100 to pass through. A grinding part 311 is disposed on the concave surface and configured to abut against the profile 100. By forming the grinding space 313 through the concave surfaces of the two grinding blocks 312, grinding can be performed simultaneously from both sides of the profile 100, improving grinding efficiency and uniformity.
[0041] More specifically, the grinding section 311 is sandpaper or a grinding wheel, which can meet the grinding needs of different roughness requirements.
[0042] Specifically, the position adjustment component 32 includes a first driver and a second driver. The output end of the first driver is connected to the second driver, enabling the second driver to move horizontally. The output end of the second driver is connected to the grinding component 31, enabling the grinding component 31 to move vertically. Through the coordinated action of the first and second drivers, the grinding component 31 can be flexibly adjusted in both the horizontal and vertical directions, thereby accurately adapting to the positional requirements of profiles 100 of different specifications and avoiding misalignment between the grinding component 31 and the profile 100 due to insufficient adjustment dimensions.
[0043] The first actuator can be a cylinder, hydraulic cylinder, or electric actuator, which can provide horizontal driving force; the second actuator can be a cylinder, hydraulic cylinder, or electric actuator, which can provide vertical driving force. The specific structure of the above components is not limited here, as long as they can achieve the above functions.
[0044] Specifically, the grinding mechanism 3 also includes a cleaning brush 33, which is located downstream of the grinding part 31 along the conveying path of the profile 100. The cleaning brush 33 is used to scrape off the debris adhering to the surface of the profile 100. By setting the cleaning brush 33, the residual debris on the surface of the profile 100 can be removed in time after grinding, ensuring the cleanliness of the surface of the profile 100.
[0045] Specifically, the automatic grinding device for pultruded profiles also includes a dust suppression auxiliary mechanism. The dust suppression auxiliary mechanism includes a water supply tank and multiple diversion pipes spaced apart in the water supply tank. One end of the diversion pipe is connected to the water supply tank, and the other end is equipped with a nozzle. The water spraying end of the nozzle is set towards the grinding workpiece 31. After the water flows through the diversion pipe and sprays out from the nozzle, it can suppress the dust in the grinding area, reduce dust floating, further improve the working environment, and avoid dust diffusion that could harm the health of the operators.
[0046] The diversion pipe can be made of metal pipe, plastic pipe or other components, which can divert and transport water flow; the nozzle can be made of atomizing nozzle, high pressure nozzle or other components, which can spray water in a specific direction. The specific structure of the above components is not limited here, as long as they can achieve the above functions.
[0047] Specifically, the surface of the chip guide plate 42 is provided with a non-stick coating. The non-stick coating can be made of materials such as polytetrafluoroethylene coating or ceramic coating, which can reduce the adhesion between the debris and the surface of the chip guide plate 42, ensuring that the debris slides smoothly into the recycling funnel 41. The specific composition of the coating is not limited here, as long as it can achieve the above-mentioned functions.
[0048] Specifically, the outlet end of the recovery funnel 41 is configured to be sealed and connected to a negative pressure generating device. This sealed connection allows the negative pressure generating device to create negative pressure within the recovery funnel 41, thereby increasing the adsorption force on debris, improving the debris collection speed, and preventing debris from remaining or flowing back into the recovery funnel 41. The negative pressure generating device can be a negative pressure fan, vacuum pump, or other components that generate negative pressure suction within the recovery funnel 41. The specific structure of these components is not limited here, as long as they achieve the aforementioned functions.
[0049] More specifically, the opening size of the recycling funnel 41 gradually decreases from top to bottom, thereby guiding and gathering the debris entering the funnel, causing the debris to quickly concentrate at the outlet end of the recycling funnel 41, and preventing the debris from being dispersed and accumulated inside the recycling funnel 41.
[0050] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
