Description

Technical Field

[0001] This utility model relates to the field of traffic sign technology, and in particular to a grinding equipment for traffic sign substrates. Background Technology

[0002] Traffic signs are the silent language of the road, conveying traffic rules, warnings, or guidance information through simple graphics, symbols, and text. Their striking colors (such as red, yellow, and blue) and reflective materials ensure visibility day and night, helping drivers and pedestrians quickly identify them. Classified by function into prohibitory, warning, and instruction types, standardized designs ensure traffic safety and order, making them an important component of the traffic management system.

[0003] Traffic signs are typically made of aluminum alloy sheets. Aluminum alloy is lightweight and strong, but during use, traffic signs can rust and accumulate environmental debris, leading to contamination and corrosion of the aluminum alloy surface, thus reducing the sign's visibility. Current polishing techniques usually involve removing the traffic sign and polishing the aluminum alloy sheet with an angle grinder. While effective, this method is inefficient and results in dents and incomplete polishing on the aluminum alloy surface, further reducing the sign's effectiveness.

[0004] To address this, we designed a grinding equipment for traffic sign substrates. Utility Model Content

[0005] The purpose of this invention is to provide a grinding device for traffic sign substrates to solve the problem of low grinding efficiency in existing technologies.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0015] The beneficial effects of this utility model are as follows:

[0016] 1. This utility model, through the setting of a second grinding surface and a first grinding plate, allows the aluminum alloy plate to be fed between the plate body and the first grinding plate when the traffic sign needs to be ground. The two sides of the aluminum alloy plate will be ground by the second grinding surface, and the bottom will also be ground by multiple first grinding rollers. The aluminum alloy plate can move forward under the drive of the first grinding rollers. While moving forward, the top surface can be ground by the first grinding plate, which further improves the grinding efficiency of the aluminum alloy plate.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0026] Reference Figures 1-6 A traffic sign substrate grinding device includes a frame 1, a plate 2 set on the top of the frame 1, and several first motors 201 set on the side walls of the plate 2. It also includes a grinding component, which is mainly set in the plate 2 above the frame 1. The aluminum alloy plate of the traffic sign substrate needs to be rectangular and its size and specifications should be compatible with the grinding component on the plate 2, which can effectively improve the grinding effect of the traffic sign substrate.

[0027] Before grinding the aluminum alloy plate, the plate 2 needs to be fixed to the frame 1 by welding. Before grinding the aluminum alloy plate, it is necessary to ensure that the frame 1 is on a stable ground to avoid shaking. Then, the first motors 201 on both sides of the plate 2 are fixed. They need to be fixed to the side wall of the plate 2 by welding through auxiliary brackets to ensure that the first motors 201 can be lifted. Then, the external power supply is connected to the first motors 201. Then, the wide edge of the aluminum alloy plate is inserted into the grinding assembly to start grinding.

[0028] Specifically, the polishing assembly includes several first polishing rollers 202 disposed on the side wall of the plate body 2, first polishing surfaces 204 symmetrically disposed on the side wall of the plate body 2, bonding strips 3 symmetrically disposed on the side wall of the plate body 2, second polishing surfaces 301 disposed on the bonding strips 3, second rods 4 symmetrically disposed on the plate body 2, first polishing plates 404 disposed on the second rods 4, first extension plates 5 symmetrically disposed on the plate body 2, second polishing rollers 506 disposed on the first extension plates 5, and auxiliary components disposed on the plate body 2.

[0029] When the aluminum alloy plate enters the grinding area of ​​the grinding assembly, it first contacts the first grinding roller 202 and grinds the bottom of the aluminum alloy plate. The first grinding roller 202 mainly removes rust and attachments by rotating and rubbing the bottom of the aluminum alloy plate. At the same time, the sides of the aluminum alloy plate are also ground by the second grinding surface 301. During the grinding of the aluminum alloy plate by the first grinding roller 202, the first grinding roller 202 also serves to transport the aluminum alloy plate within the plate body 2. During the movement of the aluminum alloy plate, the side walls contact the second grinding surface 301 to remove rust and attachments. After one-third of the aluminum alloy plate is placed on the first grinding roller 202, the first grinding plate 404 contacts the top of the aluminum alloy plate under the conveying of the second rod 4. Furthermore, it is in a semi-tightened state, ensuring that the aluminum alloy plate can achieve the grinding effect while moving. The first grinding plate 404 can effectively improve the grinding effect on the top of the aluminum alloy plate, further improving the grinding effect of the aluminum alloy plate. Subsequently, the aluminum alloy plate will leave the area of ​​the first grinding plate 404 and contact the first grinding surfaces 204 on both sides of the plate body 2. The first grinding surfaces 204 have a larger range and can effectively press against the side wall of the aluminum alloy plate and perform a transition grinding to avoid the phenomenon of chipping and curling during the grinding of the side wall of the aluminum alloy plate. Then it will enter the area of ​​the second grinding roller 506 to perform a transition grinding on the bottom of the aluminum alloy plate, so that the burrs and other conditions on the bottom of the aluminum alloy plate can be worn down, thereby improving the effect of the aluminum alloy plate after grinding.

[0030] The first grinding roller 202 is fixedly connected to the output end of the first motor 201, the first grinding surface 204 is fixedly connected to the side wall of the plate 2, and multiple slag leakage grooves 203 are symmetrically provided on the plate 2.

[0031] The first grinding roller 202 rotates mainly through the power output of the first motor 201, thereby grinding the bottom of the aluminum alloy plate. The first grinding surface 204 in the middle of the plate 2 is embedded and has abrasive particles spread on its surface. The sandpaper can be replaced to change the grinding fineness. The debris generated during the grinding of the bottom and side walls of the aluminum alloy plate can be effectively discharged from the slag drains 203 on both sides, improving the cleanliness of both sides of the plate 2 and reducing slippage during subsequent grinding of the aluminum alloy plate.

[0032] The bonding strip 3 is fixedly connected to the plate 2 by fasteners, and the second polished surface 301 is fixed to the side wall of the bonding strip 3 by fasteners.

[0033] The bonding strip 3 is fixed to both sides of the plate 2 by fasteners, which is convenient for later disassembly and replacement. The distance between the two bonding strips 3 is fixed. It is necessary to know the specifications and dimensions of commonly used traffic signs in advance to set the distance, so as to grind aluminum alloy plates of common sizes. The second grinding surface 301 is a strip structure with frosted particles on the surface in the prior art. It is fixed to the bonding strip 3 by fasteners for easy replacement in the future.

[0034] The second rod 4 is fixedly connected to the plate 2 by welding. A limiting groove 401 is provided on the second rod 4. A slider 402 is provided in the limiting groove 401. One side of the first grinding plate 404 is fixedly connected to the slider 402 by the third rod 403. The plate 2 is symmetrically provided with the first puller 406. The other side of the first grinding plate 404 is sleeved with the first puller 406 by two fourth rods 405.

[0035] The second rod 4 primarily drives the first grinding plate 404 to move up and down. The limiting groove 401 on the side wall of the second rod 4 determines the sliding length of the first grinding plate 404. The slider 402, which restricts the sliding within the limiting groove 401, is a necessary sliding component for the first grinding plate 404. The slider 402 is a sliding structure in the prior art, with its two sides embedded in the limiting groove 401 to prevent detachment. To ensure the normal sliding of the slider 402, a cylinder is installed at the bottom of the second rod 4. The third rods 403 on both sides of the first grinding plate 404 are fixed to its sides by fasteners. The third rods 403 are fixedly connected to the sliders 402 by welding to ensure the stability of the first grinding plate 404 during sliding. The first puller 406 on the other side of the first grinding plate 404 mainly controls the fifth rod 407 to ensure that the other side of the first grinding plate 404 can slide synchronously and stably, thereby improving the smoothness of the operation of the first grinding plate 404.

[0036] The first extension plate 5 is symmetrically provided with side bodies 501, and a first shaft 502 is provided between the two side bodies 501. A support rod 503 is provided on the first shaft 502, and a second motor 504 is provided at the bottom of the second rod 4. The second grinding roller 506 is fixedly connected to the second motor 504 through the second shaft 505.

[0037] Before the second grinding roller 506 performs transitional grinding on the bottom of the aluminum alloy plate, the angle of the support rod 503 on the first shaft 502 can be changed to increase the support angle of the aluminum alloy plate, thus preventing the aluminum alloy plate from undulating during the rotation of the second grinding roller 506. The second grinding roller 506 is elliptical in shape, which can effectively support the bottom of the aluminum alloy plate during grinding. At the same time, the second grinding roller 506 is fixedly connected to the output end of the second motor 504 on the basis of the second shaft 505, thereby obtaining effective drive and improving the grinding efficiency of the aluminum alloy plate. The debris generated during grinding will slide into the inclined groove 507 and be discharged through multiple slag leakage holes 508 to ensure cleanliness.

[0038] The auxiliary components include side plates 6 symmetrically arranged on the side wall of the plate body 2, a second grinding plate 604 arranged on the side plate 6, a second extension plate 7 arranged at the bottom of the plate body 2, and a plurality of third grinding rollers 702 arranged on the second extension plate 7.

[0039] The side plate 6 has a second puller 601 on its side wall. The second puller 601 is fixedly connected to the second grinding plate 604 via a pull rod 603. The second extension plate 7 has multiple third motors 701.

[0040] When the aluminum alloy plate reaches the area of ​​side plate 6, it will contact multiple support rods 205. The second grinding plate 604 can be moved downward by the second pull-out device 601 to perform secondary fine grinding on the top of the aluminum alloy plate, ensuring better flatness and gloss reflection. The second pull-out device 601 mainly connects to the pull-out rod 603 on the side wall of side plate 6 through the pull-out end 602 at the top. The side wall of the second grinding plate 604 is fixed to the pull-out rod 603 by fasteners, so that the second grinding plate 604 can move on the side plate 6. When the aluminum alloy plate enters the area of ​​the third grinding roller 702, the third grinding roller 702, driven by the third motor 701, performs fine grinding on the bottom of the aluminum alloy plate, thereby ensuring the grinding effect of the aluminum alloy plate and facilitating the later development of traffic signs.

[0041] The working principle of this utility model is as follows:

[0042] When the removed traffic sign needs polishing, simply clean the surface marking area, then insert the aluminum alloy plate into the plate body 2. The aluminum alloy plate will initially contact multiple first polishing rollers 202 and move inward under the polishing of the first polishing rollers 202. During the forward movement, the sides of the aluminum alloy plate will contact the second polishing surface 301, achieving the effect of side wall polishing. Then, operate the cylinder to make the slider 402 slide downward, driving the first polishing plate 404 on the slider 402 to move downward and press against the top of the aluminum alloy plate. Top polishing can be performed during the movement of the aluminum alloy plate. After the initial polishing, the sidewalls and bottom of the aluminum alloy plate undergo a transition polishing process with the cooperation of the first polishing surface 204 and the second polishing roller 506 to prevent surface chipping and damage. The plate then continues to the area of ​​the second polishing plate 604, where the second puller 601 drives the plate to perform a second fine polishing on the top of the aluminum alloy plate, making it semi-smooth. The plate then enters the area of ​​the third polishing roller 702 for a second fine polishing on the bottom, ensuring the best polishing effect. With the second grinding surface 301 and the first grinding plate 404 in place, when the traffic sign needs to be ground, the aluminum alloy plate is simply fed between the plate body 2 and the first grinding plate 404. The two sides of the aluminum alloy plate will be ground by the second grinding surface 301, and the bottom will also be ground by multiple first grinding rollers 202. The aluminum alloy plate can move forward under the drive of the first grinding rollers 202, and the top surface can be ground by the first grinding plate 404 while moving forward, which further improves the efficiency of grinding the aluminum alloy plate.

[0043] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
