Description

Technical Field

[0001] This utility model relates to a trimming device for vehicle license plate raw materials, belonging to the technical field of trimming devices. Background Technology

[0002] In modern traffic management systems, license plates serve as crucial vehicle identification, and every step of their manufacturing process is vital. The trimming process of license plate raw materials directly impacts the quality and appearance of the plate. Early license plate production primarily used metal materials such as sheet metal and aluminum plates. These materials were relatively inexpensive but difficult to process. The trimming process relied mainly on manual labor using simple tools. Workers used scissors or small cutting machines to cut the raw materials, which was not only inefficient but also difficult to guarantee cutting accuracy. Due to the subjectivity of manual operation, the cut edges were uneven, affecting the overall aesthetics of the license plate. If the trimming process is skipped and the material is directly stamped, the untrimmed raw material will have irregular burrs or excess material edges. During stamping, the excess material around the substrate, not pre-separated, will adhere to the forming substrate or mold surface in a continuous sheet. This continuous waste cannot naturally break apart during stamping and must be continuously wound and collected using specialized roll-up equipment. Therefore, there is an urgent need to design a trimming device for license plate materials to solve the above problems. Utility Model Content

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] 1. In this utility model, according to the width requirements of the license plate, the first mounting seats on both sides are moved and fixed by the adjusting and fixing mechanism. As the raw material is fed into the platform by external equipment, it passes through the first guide roller and the flattening roller, and then through the cutting blade. The cutting blade cuts both sides of the raw material. After cutting, the raw material is flattened again by the rolling roller and then enters the edge grinding mechanism to grind the edges. After grinding, the raw material is sent to the external stamping mechanism for stamping, thereby reducing the problem of edge waste adhesion. Thus, this utility model achieves the effect of trimming both sides of the license plate raw material by adjusting the position of the cutting blade, which has the advantages of consistent product quality and reduced manual workload.

[0014] 2. In this utility model, before the edge grinding operation, the second mounting seats on both sides are moved according to the width of the material after edge trimming to adjust the position of the edge grinding roller, so that the edge grinding roller is in contact with both sides of the material after trimming. After determining the position of the second mounting seat, the lower end of the third bolt is tightened to pass through the second mounting seat and the second slide groove and connect with the second fixing block. The second bolt is then continuously tightened so that the second mounting seat and the second fixing block are close to the second mounting plate for fixation. After the material passes through the edge grinding roller, the two sides of the material will be ground to make them smoother. Then, the material passes between the concave roller and the convex roller. Driven by the motor, the rotating shaft rotates, which drives the concave roller to rotate and, through the first gear and the second gear, causes the convex roller to rotate, thereby grinding the upper and lower parts of the side of the material as it passes through.

[0020] Preferably, such as Figure 1 and Figure 2 As shown, the adjusting and fixing mechanism 7 includes a first sliding groove 20 on the first mounting plate 5 and a first through hole 21 on the first mounting base 6. The first mounting base 6 is provided with a first bolt 22, the end of which passes through the first through hole 21 and the first sliding groove 20 and is threadedly connected to a first fixing block 23. After adjusting the position of the first mounting base 6, the first bolt 22 is passed through the first through hole 21 and the first sliding groove 20 and then threadedly connected to the first fixing block 23. The first bolt 22 is continuously tightened, so that the first mounting base 6 and the first fixing block 23 are close to the first mounting plate 5, thereby fixing the first mounting base 6.

[0021] Preferably, such as Figure 1 As shown, a square groove 11 is provided on the table surface of the table body 1. The square groove 11 is located below the cutting blade 8. A waste basket is placed below the square groove 11. The waste material cut by the cutting blade 8 will enter the waste basket, realizing the centralized collection and treatment of waste material and avoiding the waste material from scattering and affecting the cleanliness of the production line.

[0022] Preferably, such as Figure 1 and Figure 2As shown, the first mounting base 6 has a mounting groove 12, and the cutting blade 8 is disposed in the mounting groove 12. The side of the first mounting base 6 has a threaded hole 13, which communicates with the mounting groove 12. A second bolt 14 is provided on the threaded hole 13, and the inner end of the second bolt 14 passes through the threaded hole 13 and abuts against the cutting blade 8. When the blade needs to be replaced, the second bolt 14 is loosened to allow the cutting blade 8 to fall out. Then, the new cutting blade 8 is placed into the mounting groove 12, and the second bolt 14 is tightened so that its inner end abuts against the new cutting blade 8, thus completing the replacement.

[0023] Preferably, such as Figure 1 and Figure 2 As shown, the edge grinding mechanism 10 includes a second mounting plate 30 respectively disposed between the mounting side plates 2 and located behind the flattening roller 4. The second mounting plate 30 is provided with a second sliding groove 31, and a second mounting seat 32 is provided above the second sliding groove 31. An edge grinding roller 33 is vertically disposed on the second mounting seat 32. The surface of the edge grinding roller 33 is covered with a diamond abrasion wear-resistant layer for grinding the cutting edge of the raw material. A third bolt 34 is provided at the upper end of the edge grinding roller 33. The third bolt 34 passes through the edge grinding roller 33, the second mounting seat 32 and the second sliding groove 31 and is then threaded to a second fixing block 35. The edge grinding mechanism 10 further includes a third mounting plate 36 symmetrically arranged on the upper end of the platform 1, located behind the second mounting plate 30. A concave roller 37 and a convex roller 38 are rotatably connected to the third mounting plate 36, their roller surfaces fitting together. A motor 39 is located on the outer side of one side of the mounting side plate 2, and the output end of the motor 39 is connected to a rotating shaft 40, which is tumbledly connected to the concave roller 37. A first gear 41 is mounted on the rotating shaft 40. The shaft of the convex roller 38 extends through the third mounting plate 36 and is connected to a second gear 42, which is connected to and meshes with the first gear 41. A second guide roller 43 is located between the second mounting plate 30 and the third mounting plate 36, and the second guide roller 43 is aligned with the feed end of the edge grinding mechanism 10. Before the edge grinding operation, the second mounting seats 32 on both sides are moved according to the width of the material after trimming to adjust the position of the edge grinding roller 33, so that the edge grinding roller 33 fits against the two sides of the material after trimming. After determining the position of the second mounting seat 32, the lower end of the third bolt 34 is passed through the second mounting seat 32 and the second slide groove 31 and connected to the second fixing block 35 by tightening the third bolt 34, so that the second mounting seat 32 and the second fixing block 35 are close to the second mounting plate 30 for fixation. After the material passes through the edge grinding roller 33, the two sides of the material will be ground to make it smoother. Then it passes between the concave roller 37 and the convex roller 38. Driven by the motor 39, the rotating shaft 40 rotates. The rotating shaft 40 drives the concave roller 37 to rotate and, through the first gear 41 and the second gear 42, causes the convex roller 38 to rotate, so that the upper and lower parts of the side of the material are ground as it passes through, eliminating the cutting burrs and improving the edge flatness.

[0024] Preferably, such as Figure 1 and Figure 2 As shown, the inner side of the mounting side plate 2 is provided with a guide rail 50, and a slider 51 is slidably connected to the guide rail 50.

A fourth mounting plate 53 is provided between the sliders 51, and a mounting block 54 is slidably connected to the fourth mounting plate 53. A sensor 55 is slidably connected to the rear end of the mounting block 54. In this embodiment, the sensor 55 is an infrared sensor of model E3F-DS10C4. The movement of the sensor 55 in the X-axis direction is controlled by the slider 51 sliding on the guide rail 50, and the slider 51 is fixed by tightening the fourth bolt 52 so that its inner end abuts against the guide rail 50. The movement of the sensor 55 in the Y-axis direction is controlled by sliding the mounting block 54. When adjusting the position of the sensor 55, the sensor 55 is moved upward along the mounting block 54 in the Z-axis direction to prevent the sensor 55 from colliding with other components during the movement. The sensor 55 is moved to a suitable position to detect whether there is raw material input, providing signal feedback for the automated control of the production line.

[0025] Working principle:

[0026] Raw material guiding and leveling: The raw material is guided by the first guide roller 3 at the front end of the platform 1 to maintain a stable conveying direction and avoid deviation. Then it enters between two pairs of upper and lower flattening rollers 4. Through the rolling action of the flattening rollers 4, the curling or wrinkles on the surface of the raw material are eliminated, providing a flat processing benchmark for subsequent trimming.

[0027] Cutting width adjustment and edge trimming: Based on the required trimming width of the raw material, the position of the first mounting base 6 on the first mounting plate 5 is moved by adjusting the fixing mechanism 7, thereby adjusting the spacing of the cutting blades 8 on both sides. After determining the position, the first bolt 22 is tightened to fix the first mounting base 6, ensuring the positioning accuracy of the cutting blades 8. After the raw material is flattened, it continues to move forward, and the cutting blades 8 precisely cut off the excess edge material on both sides. The waste generated from cutting falls into the waste basket below through the square groove 11 on the platform 1 for centralized collection.

[0028] Edge Grinding Process: After being cut, the raw material enters the edge grinding mechanism 10. First, it passes through the adjustable edge grinding roller 33. The position of the second mounting base 32 on the second slide groove 31 is adjusted according to the width of the cut material, so that the edge grinding roller 33 fits against the two sides of the raw material. After fixing, the cut edges are initially ground to remove burrs. Then, the raw material enters between the concave roller 37 and the convex roller 38. The motor 39 drives the rotating shaft 40 to rotate the concave roller 37. Through the meshing transmission of the first gear 41 and the second gear 42, the convex roller 38 rotates synchronously in the opposite direction. The mating roller surface contours of the two rollers are used to finely grind the upper and lower surfaces of the raw material sides, further improving the edge smoothness. During the grinding process, the second guide roller 43 guides the raw material to pass smoothly through the edge grinding area.
