DETAILED DESCRIPTION

[0027] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0028] The embodiment of the present application provides a round rod grinding device for processing road signboards, which can solve the problem that round rod grinding devices in the related art mostly use manual loading and cannot load automatically, thus affecting production efficiency.

[0029] See also Figure 1 - Figure 3 A round rod grinding device for road sign processing includes: a frame 1, an automatic feeding mechanism 2 and a grinding mechanism 3, wherein the automatic feeding mechanism 2 is used for automatic feeding and unloading of round rods, and the grinding mechanism 3 is used for grinding round rods;

[0030] The automatic feeding mechanism 2 includes a material box 21, a feeding assembly 22 and a conveying assembly 23. The material box 21 is arranged on the frame 1 and is used to store round rods. The feeding assembly 22 is used to feed the round rods in the material box 21 to the conveying assembly 23. The conveying assembly 23 is used to convey the round rods to the grinding mechanism 3.

[0031] The grinding mechanism 3 includes two grinders 31 arranged opposite to each other on both sides of the conveying assembly 23 .

[0032] The round rods are first placed in the material box 21, and the space inside the material box 21 is used for storing and sorting the round rods.

[0033] When the grinding operation needs to start, the feeding assembly 22 starts to work, and the feeding assembly 22 drives the picking plate 222 to move up and down, and the picking groove 2221 on the picking plate 222 can accurately grab a round rod at the bottom of the material box 21.

[0034] After the pick-up plate 222 lifts the round rod to a certain height, the round rod is guided to the conveying assembly 23 by the guide plate 223. The top of the guide plate 223 is tilted to ensure that the round rod can slide smoothly into the conveying assembly 23. The conveying assembly 23 smoothly conveys the round rod to the working area of ​​the grinding mechanism 3.

[0035] When the round bar is transported to the working area of ​​the grinding mechanism 3, two oppositely arranged grinding machines 31 start to work. They are respectively located on both sides of the round bar and grind the round bar simultaneously.

[0036] The grinding machine 31 removes burrs, oxide layers or uneven parts from the surface of the round rod by means of a high-speed rotating grinding wheel or other grinding tools, so as to achieve a smooth and flat effect.

[0037] The design of the automatic feeding mechanism 2 realizes the automatic feeding of round rods, reduces the cumbersome operation of manual feeding, greatly improves production efficiency, and reduces the labor intensity of operators.

[0038] The grinding mechanism 3 uses two grinders 31 arranged opposite to each other, which can grind the round rod at the same time, thereby ensuring the uniformity and consistency of grinding and improving the processing quality.

[0039] The smooth conveying of the conveying assembly 23 also reduces the vibration and displacement of the round rod during the grinding process, further ensuring the processing quality.

[0040] Automated operation reduces direct contact between operators and equipment, reducing the risk of safety accidents.

[0041] Specifically, in this embodiment, the material box 21 has a chamber for storing round rods, the top of the material box 21 is open, and a through hole is formed on one side of the material box 21 close to the feeding assembly 22.

[0042] The bottom of the material box 21 is inclined downward near the end of the feeding assembly 22.

[0043] The material box 21 is used as a container for storing round rods, and a chamber for storing round rods is designed inside the material box 21. The top of the material box 21 is open, which is convenient for operators to add round rods therein. A through hole is opened on one side of the material box 21 near the feeding assembly 22 to ensure that the feeding assembly 22 can pass smoothly.

[0044] The bottom of the material box 21 is tilted downward near one end of the feeding assembly 22, using gravity to help the round rods to concentrate on the through hole. When the feeding assembly 22 is working, due to the tilted bottom design, the round rods will naturally roll toward the through hole 211, making it easier to be grabbed by the picking plate 222.

[0045] Preferably, the feeding assembly 22 in this embodiment includes a lifting member 221, two material picking plates 222, and a group of guide plates 223. The lifting member 221 is arranged on the frame 1, and the two material picking plates 222 are relatively arranged on the lifting member 221. The lifting member 221 is used to control the lifting and lowering of the material picking plate 222, and the material picking plate 222 is used to extract round rods. A group of guide plates 223 are relatively arranged on the material box 21, and the guide plates 223 are used to guide the extracted round rods to move to the conveying assembly 23.

[0046] Furthermore, a feeding trough 2221 is provided on the feeding plate 222 , and the feeding trough 2221 is inclined toward the side close to the conveying assembly 23 . The two feeding plates 222 are located between a group of guide plates 223 , and the top end of the guide plate 223 is inclined downward toward the end close to the conveying assembly 23 .

[0047] The lifting member 221 controls the up and down movement of the material taking plate 222 through its lifting movement. When the lifting member 221 rises, the material taking plate 222 also rises.

[0048] The material taking plate 222 is provided with a material taking groove 2221, which is inclined toward the side close to the conveying assembly 23, so as to help the round rod to automatically roll into the groove during the material taking process. When the material taking plate 222 descends to the bottom of the material box 21, the round rod will naturally roll onto the material taking plate 222 because the bottom of the material box 21 is inclined toward one end of the feeding assembly 22.

[0049] When the lifting member 221 starts to rise, it drives the feeding plate 222 and the round rod thereon to move upward together. As the feeding plate 222 rises, the round rod is taken away from the material box 21. At this time, the round rod is free from the restriction of the material box 1 and automatically rolls into the feeding trough 2221. At this time, the round rod is located above the two guide plates 223. Subsequently, the lifting member 221 descends, causing the feeding plate 222 to descend as well. A group of guide plates 223 begin to play a role, and the descending round rod will contact the guide plates 223. As the lifting member 21 is reset, the round rod falls above the guide plates 223. Since the top end of the guide plates 223 is tilted downward toward the end close to the conveying assembly 23, it is ensured that the round rod can smoothly slide onto the receiving platform 231 of the conveying assembly 23.

[0050] In summary, through the improved design of the material picking plate 222, the material picking trough 2221 and the guide plate 223, and the coordinated work of the feeding component 22, the material box 21 and the conveying component 23, accurate and smooth feeding of round rods is achieved, production efficiency is improved, labor intensity is reduced, and it has strong adaptability.

[0051] It can be understood that in this embodiment, a through hole for accommodating the material taking plate 222 is provided between the material box 21 and the frame 1 .

[0052] Specifically, a connecting through hole is provided at the bottom of the material box 21 and the top of the frame 1, and the through hole is used for the passage of the material taking plate 222. Moreover, the through hole at the bottom of the material box 21 is adapted to the diameter of a single round rod, so that when the material taking plate 22 is raised, only a single round rod will be lifted.

[0053] like Figure 4 As shown, specifically, in this embodiment, the lifting member 221 includes a cylinder 2211 disposed at the bottom of the frame 1, and a mounting frame 2212 is disposed at the bottom end of the piston rod of the cylinder 2211. The mounting frame 2212 and the two material-collecting plates 222 are disposed at both ends of the mounting frame 2212. The mounting frame 2212 is U-shaped.

[0054] The cylinder 2211 is installed at the bottom of the frame 1 and provides up and down reciprocating linear motion through air pressure drive.

[0055] The mounting frame 2212 is fixed to the bottom end of the piston rod of the cylinder 2211 and moves up and down as the piston rod expands and contracts. The mounting frame 2212 is U-shaped, which is convenient for fixing the two material taking plates 222 and maintaining their relative positions. The two material taking plates 222 are relatively arranged at both ends of the mounting frame 2212 to ensure that they can be raised and lowered synchronously under the drive of the cylinder 2211.

[0056] like Figure 5 As shown, preferably, the conveying assembly 23 in this embodiment includes a plurality of receiving platforms 231 arranged on the frame 1, the receiving platforms 231 are provided with a travel groove 2311 for accommodating the round rod, two grinders 31 are located on both sides of the receiving platforms 231, two wire wheels 232 are arranged on the frame 1 for relative rotation, two driving ropes 233 are connected for transmission between the two wire wheels 232, the driving ropes 232 are located inside the travel groove 2311 and are used to support the round rod, a reducer 234 is arranged on the frame 1, and the output shaft of the reducer 234 is connected to any wire wheel 232, and a driving motor 235 is arranged on the frame 1, and the output shaft of the driving motor 235 is connected to the input shaft of the reducer 234.

[0057] The receiving platform 231 is arranged on the frame 1 and has a travel groove 2311 on its surface. The size of the travel groove 2311 matches the round rod, ensuring that the round rod can be stably placed in the groove and move along the path of the groove.

[0058] Two grinders 31 are located on both sides of the receiving platform 231. When the round bar moves on the receiving platform 231, it will be grinded by the two grinders 31 from both sides at the same time, thereby achieving efficient and uniform processing.

[0059] Two wire wheels 232 are relatively rotatably arranged on the frame 1, and are connected by two driving ropes 233. These driving ropes 233 are located inside the travel groove 2311, and when they rotate, they support and push the round rod to move in the travel groove 2311.

[0060] The speed reducer 234 is mounted on the frame 1, and its output shaft is connected to any one of the wire wheels 232. Through the speed reducer 234, the rotation speed of the wire wheel 232 can be controlled, thereby adjusting the moving speed of the round rod.

[0061] The output shaft of the driving motor 235 is connected to the input shaft of the reducer 234 to provide power for the entire conveying assembly 23. By controlling the speed and direction of the driving motor 235, the moving speed and direction of the round rod can be controlled.

[0062] Furthermore, the limiting mechanism 4 in this embodiment is arranged inside the material box 21 and is used to guide the round rod inside the material box 21 to slide;

[0063] The limiting mechanism 4 includes a guide rod 41 disposed inside the material box 21 , and a pressure plate 42 is slidably disposed on the guide rod 41 .

[0064] The limiting mechanism 4 is used to ensure that the round rods inside the material box 21 can slide in an orderly and stable manner during the feeding process, thereby avoiding confusion and accumulation between the round rods.

[0065] The guide rod 41 is arranged inside the material box 21, and usually extends along the length direction or the width direction of the material box. Its main function is to provide a fixed path.

[0066] The pressing plate 42 can slide on the guide rod 41. The sliding position of the pressing plate 42 can be adjusted according to the length and state of the round rod inside the material box 21.

[0067] like Figure 6 As shown, in this embodiment, a slide 5 is provided on the frame 1. The slide 5 is located at the end of the grinder 31 away from the conveying assembly 23 and is used to guide the round rod to fall after grinding.
