Description

Technical Field

[0001] The present invention relates to the technical field of warning sign processing, and specifically relates to a processing and grinding device for outdoor warning signs. Background Art

[0002] During the processing and manufacturing of outdoor warning signs, grinding is a crucial step. Through grinding, the surface of the metal plate used to make the warning sign can be made flat and smooth, facilitating subsequent film pasting or painting. The Chinese patent application with the application number 202121659581.1 discloses "a processing device for road warning signs. A processing device for road warning signs includes a T-shaped chute, a clamping plate, a slider, and a grinding wheel. The two sliders are respectively slidably connected in the two T-shaped chutes, the two clamping plates are respectively slidably connected to the two sliders, the two clamping plates can rotate on the two sliders, and the grinding wheel is connected to the two T-shaped chutes. A processing device for road warning signs further includes a sliding iron plate and a spring I. The two sliding iron plates are respectively slidably connected in the two T-shaped chutes, one end of each of the two springs I is fixedly connected to the two sliding iron plates respectively, the other end of each of the two springs I is fixedly connected to the two T-shaped chutes respectively, and the two sliders can press down the two sliding iron plates. The present invention provides a processing device for road warning signs, and its beneficial effect is that it can comprehensively grind the peripheries of triangular and circular warning signs.";

[0003] This technical solution only solves the problem that the peripheries of triangular and circular warning signs cannot be comprehensively ground, but this technical solution is only applicable to warning signs with a relatively small area. For common outdoor warning signs, they are often large in size, and it is difficult to achieve double-sided clamping and grinding. Therefore, currently, it is common to place the metal plate on the ground and then grind it by manually holding a grinding device. This not only has low grinding efficiency and unstable grinding quality. In addition, when cutting the metal plate used to make outdoor warning signs, burrs are likely to be generated at the edges. Therefore, it is necessary to trim the edges during grinding, and existing devices often cannot perform grinding and edge trimming well at the same time. Summary of the Invention

[0021] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0022] 1. By designing and installing a horizontal fixing mechanism and a vertical fixing mechanism, the present invention drives two horizontal fixing plates to move simultaneously towards the bent parts of the metal plate used for making warning signs, so that the two horizontal fixing plates hold the bent parts at the left and right ends of the metal plate, fixing the left and right ends of the metal plate. When the horizontal fixing plates move, they drive the longitudinal translation blocks to move inside the horizontal sliding grooves. By driving two longitudinal translation frames to move towards the metal plate at the same time, and when the longitudinal translation frames move, they drive the longitudinal translation blocks to move inside the longitudinal translation grooves, so that the four clamping plates simultaneously clamp the front and rear sides of the bent part of the metal plate, fixing the metal plate on the top end of the grinding machine tool, avoiding the offset of the metal plate during grinding and preventing the influence on the grinding effect of the metal plate.

[0023] 2. The present invention is designed and installed with a surface grinding mechanism and a front-back reciprocating mechanism. By driving the grinding drive box and the reciprocating drive box to move towards the metal plate simultaneously, the two grinding rollers move towards the metal plate. During this process, the two grinding rollers are driven to rotate in the same direction simultaneously, and at the same time, the reciprocating frame is driven to perform forward and backward reciprocating swinging movements in the reciprocating drive box, so that the reciprocating sleeve drives the two grinding rollers to perform forward and backward reciprocating movements. By the two grinding rollers performing forward and backward reciprocating movements while rotating, the grinding quality of the surface of the metal plate is improved, the labor intensity of the staff is reduced, and the processing efficiency of outdoor warning signs is enhanced.

[0024] 3. The present invention is designed and installed with an edge grinding mechanism and an up-down reciprocating mechanism. While driving the two grinding rollers to translate and grind the surface of the metal plate, the two groups of grinding wheels at both ends are driven to move simultaneously. The grinding wheels are driven to rotate to grind the edges of the metal plate, and at the same time, the wheel frame is driven to perform up and down reciprocating movements in the movable groove, so that the rotating shaft and the grinding wheels follow the wheel frame to perform up and down reciprocating movements simultaneously, and the burrs generated during the cutting of the metal plate are effectively ground and trimmed.

[0052] Working principle: When the present invention is in use, the outdoor warning sign board plates with both ends bent are placed on the two horizontal fixing plates 206. Then, the first turning handle 204 is rotated. The first turning handle 204 drives the first double-threaded rod 203 to rotate. When the first double-threaded rod 203 rotates, the two horizontal translation frames 205 are driven to move away from the middle of the grinding machine tool 1. At this time, the top ends of the horizontal translation frames 205 move in the horizontal translation grooves 201, so that the horizontal fixing plates 206 follow the horizontal translation frames 205 to move. The left and right ends of the metal plate are fixed by the two horizontal fixing plates 206 against the bent parts at the left and right ends of the metal plate. Then, the second turning handle 305 is rotated. The second turning handle 305 drives the second double-threaded rod 304 at the right end to rotate, and drives the second double-threaded rod 304 at the left end to rotate simultaneously through the first synchronous belt 306. When the second double-threaded rod 304 rotates, the two longitudinal translation frames 307 are driven to move towards the metal plate simultaneously.

And when the horizontal fixing plates 206 move, the longitudinal translation blocks 302 are driven to move inside the horizontal sliding grooves 308. The clamping plates 303 are driven to move simultaneously through the longitudinal translation blocks 302. The front and rear sides of the bent part of the metal plate are clamped by the clamping plates 303.

Drive the second reciprocating rod 704 to rotate through the reciprocating wheel 703. Insert the second reciprocating rod 704 into the upper and lower reciprocating grooves 701, so that the wheel frame 608 performs up and down reciprocating movements in the movable groove 607, so that the rotating shaft 609 and the grinding wheel 611 follow the wheel frame 608 to perform up and down reciprocating movements simultaneously. After the third motor 706 is started, drive the grinding shaft 710 to rotate through the third drive belt 712. When the grinding shaft 710 rotates, drive the rotating shaft 609 to rotate through the second shaft key 711, and drive the grinding wheel 611 to rotate through the rotating shaft 609. At this time, the grinding wheel 611 performs up and down reciprocating movements while rotating;

[0055] Start the first motor 403, and drive the two translation threaded rods 401 to rotate simultaneously through the second synchronous belt 402. When the translation threaded rods 401 rotate, drive the grinding drive box 404 and the reciprocating drive box 501 to move simultaneously towards the metal sheet. Drive the two connecting frames 604 to move simultaneously through the synchronous rod 511, so that the two grinding rollers 408 and the grinding wheels 611 at the bottom ends of the two connecting frames 604 move towards the metal sheet simultaneously.
