Description

Technical Field

[0001] This invention relates to a processing production line for vehicle license plate substrates, belonging to the technical field of processing production lines. Background Technology

[0002] In modern traffic management systems, license plates are key identifiers for vehicle identification, and their accuracy, efficiency, and quality stability are crucial for the smooth operation of traffic management. As the fundamental component of license plates, the processing quality and production efficiency of the license plate substrate directly affect the overall quality of license plate production. Early on, license plate substrate processing relied primarily on manual labor. Workers used simple tools, such as cutting knives and stamping dies, to process raw materials. This method was not only labor-intensive but also inefficient, making it difficult to meet the demands of large-scale production. Furthermore, due to the significant errors inherent in manual operation, the dimensional accuracy and surface quality of the substrate were difficult to guarantee, resulting in inconsistent overall license plate quality. With technological advancements, semi-automated processing equipment has gradually been applied to license plate substrate production. While these devices have improved production efficiency and product quality to some extent, several problems remain. For example, poor coordination between equipment necessitates frequent manual intervention, leading to a less smooth production process; the degree of automation is limited, preventing fully automated production and still requiring substantial manpower; and processing accuracy and stability still need improvement to meet increasingly stringent quality requirements. Therefore, there is an urgent need to develop a high-efficiency, precise, and highly automated production line for processing vehicle license plate substrates to solve the above problems.

When the upper and lower molds are separated, the lower end face of the stamping plate is lower than the lower end face of the cutting block. The feeding end of the lower mold is slidably connected to multiple third guide pillars, and a lifting block is fixedly connected above the third guide pillars, located below the cutting block at the feeding end. The cutting block at the discharge end extends beyond the upper end face of the lower mold. A first spring surrounds the outer side of each third guide pillar.

[0012] In the aforementioned processing production line for vehicle license plate substrates, the lower mold is provided with first guide posts at the four corners, and guide sleeves are slidably connected to the upper part of the first guide posts. A second spring is provided below the guide sleeves and surrounds the outer side of the first guide posts.

[0014] The aforementioned production line for processing vehicle license plate substrates includes a conveying mechanism comprising a mounting frame, a first conveyor belt mounted on the mounting frame, the upper surface of the first conveyor belt being flush with the upper surface of the lower mold; a gap exists between the first conveyor belt and the lower mold, and a third guide roller located on the gap is mounted on the mounting frame; a second conveyor belt located below the first conveyor belt is mounted on the mounting frame, and the feed end of the second conveyor belt is located below the gap.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] 1. In this invention, the raw material is coiled and hung on a hanging cylinder mechanism. The open end of the raw material coil is then flattened by a flattening roller of a rolling and trimming mechanism. The position of the cutting blade is adjusted according to the width requirements of the substrate by a blade adjustment mechanism. The raw material is cut to the required width by the cutting blade. Afterward, the raw material passes through a stamping mechanism's processing mold, causing the raw material to be segmented into substrates with pre-drilled holes. The formed substrate material and the waste generated during the segmentation process are separated and transported by a conveying mechanism. Therefore, this invention achieves fully automated production of license plate substrates, with advantages such as a high degree of automation and improved production efficiency.

[0018] 2. In this invention, based on the width requirements of the substrate, the first mounting seats on both sides are moved. After determining the position of the first mounting seats, the lower end of the first bolt is tightened to pass through the first mounting seat and the first sliding groove and connect with the first limiting plate. The first bolt is then continuously tightened so that the first mounting seat and the first limiting plate are close to the first mounting plate for fixation. When the blade needs to be replaced, the second bolt is loosened to allow the cutting blade to fall. Then, the new cutting blade is placed in the mounting groove, and the second bolt is tightened so that its inner end abuts against the new cutting blade, completing the replacement. After the cut material is rolled flat by the flattening roller, it enters the edge grinding mechanism and moves according to the size of the substrate. The second mounting seats on both sides adjust the position of the grinding roller. After the position of the second mounting seat is determined, 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 limiting plate. The second bolt is then tightened to make the second mounting seat and the second limiting plate close to the second mounting plate for fixation. After the raw material passes through the grinding roller, the two sides of its cut surface are ground to make it smoother. Then it passes between the concave roller and the convex roller. Driven by the first motor, the first rotating shaft rotates. The first rotating shaft drives the concave roller to rotate and, through the first gear and the second gear, makes the convex roller rotate, so that the upper and lower parts of the side surface of the raw material are ground as it passes through.

[0019] 3. In this invention, the stamping mechanism moves the upper die of the processing mold up and down through the stamping machine body. When the raw material moves to the lower die, the stamping machine body causes the upper die to descend. The stamping plate first contacts the raw material and flattens it. As the upper die continues to descend, the punching pin passes through the punching slot downwards. The waste material generated by punching falls into the lower die through the unloading slot. At the same time, the cutting blocks at both ends divide the raw material into segments to form a substrate. Then the upper die rises and the raw material continues to move forward a certain distance, pushing the already cut substrate into the conveying mechanism. At the same time, unprocessed raw material enters the lower die. The upper die descends again to cut, and the process is repeated. Attached Figure Description

Detailed Implementation

[0028] The present invention will be further described below with reference to the accompanying drawings and embodiments, but this should not be construed as limiting the present invention.

[0029] Example: A production line for processing vehicle license plate substrates, configured as follows Figure 1-7 As shown, it includes a hanging cylinder mechanism 1, such as Figure 7 As shown, the hanging mechanism 1 includes a first body 100, in which a hanging rod 101 controlled by a drive mechanism is provided. The rod is made of high-strength alloy steel, which is strong, wear-resistant, and capable of stably supporting the weight of the raw material roll. The hanging rod 101 is used to hang aluminum raw material rolls. Aluminum is lightweight and corrosion-resistant, and is a commonly used material for license plate substrates. The feeding speed is controlled by the rotation speed of the hanging rod 101, which is used to hang the raw material rolls. The processing production line also includes:

[0030] The rolling and trimming mechanism 2 is located at the discharge end of the hanging cylinder mechanism 1; for example... Figure 2 and Figure 3As shown, the rolling and trimming mechanism 2 includes a second body 200, on which a blade adjustment mechanism 201 and multiple pairs of vertically arranged flattening rollers 202 are mounted. The flattening rollers 202 are made of rubber with moderate hardness and have undergone special surface treatment. During the rolling process, they can effectively flatten the raw material without damaging the surface of the aluminum raw material. The adjusting end of the blade adjustment mechanism 201 is equipped with a cutting blade 203. The rolling and trimming mechanism 2 flattens the raw material roll using the flattening rollers 202, adjusts the spacing between the cutting blades 203 using the blade adjustment mechanism 201 to meet the processing width, and trims both sides of the raw material using the cutting blades 203. The second body 200... A mounting side plate 204 is symmetrically arranged on both sides, and a plurality of first guide rollers 205 are provided at the end of the mounting side plate 204 facing the hanging cylinder mechanism 1; the flattening roller 202 is arranged between the mounting side plates 204 and located behind the first guide rollers 205; the blade adjustment mechanism 201 is arranged between adjacent flattening rollers 202; the rear end of the flattening roller 202 is provided with a grinding mechanism 206; the blade adjustment mechanism 201 includes a first mounting plate 207 horizontally arranged between the mounting side plates 204, a first sliding groove 208 is symmetrically arranged on both sides of the first mounting plate 207, a first mounting seat 209 is provided above the first sliding groove 208, and a first bolt 210 is provided on the first mounting seat 209. A first limiting plate 211 is threadedly connected to the first mounting base 209 and the first sliding groove 208; the first mounting base 209 is provided with a mounting groove 212, and the cutting blade 203 is disposed in the mounting groove 212; a second bolt 213 is provided on the side of the first mounting groove 212, and the inner end of the second bolt 213 penetrates into the mounting groove 212 and abuts against the cutting blade 203; the second platform 200 is provided with a square groove located below the cutting blade 203, and a waste basket located below the square groove is provided in the second platform 200. The waste cut by the cutting blade 203 enters the waste basket through the square groove for collection; according to the width requirement of the substrate, the first mounting bases 209 on both sides are moved to determine the width. After the first mounting base 209 is positioned, the lower end of the first bolt 210 is tightened to pass through the first mounting base 209 and the first sliding groove 208 and connect with the first limiting plate 211. The first bolt 210 is then continuously tightened so that the first mounting base 209 and the first limiting plate 211 are pressed against the first mounting plate 207 for fixation. When the blade needs to be replaced, the second bolt 213 is loosened to allow the cutting blade 203 to fall out. Then, the new cutting blade 203 is placed into the mounting groove 212, and the second bolt 213 is tightened so that its inner end abuts against the new cutting blade 203, thus completing the replacement. After the cut material is rolled flat by the rolling roller again, it enters the edge grinding mechanism 206 to grind the edges of the material.

[0031] The stamping mechanism 3 is located at the discharge end of the rolling and trimming mechanism 2; for example... Figure 4 and Figure 5As shown, the stamping mechanism 3 includes a stamping machine body 300, and a processing die 301 is provided at the stamping end of the stamping machine body 300. The stamping mechanism 3 uses the stamping machine body 300 to cause the processing die 301 to cut the raw material and punch holes in it, thus completing the processing of the license plate base plate. The processing die 301 includes an upper die 302 and a lower die 303. Both the upper die 302 and the lower die 303 of the processing die 301 are made of high-quality die steel and have undergone quenching and other treatments, resulting in high hardness. It has good toughness and can withstand greater impact and pressure; multiple second guide pillars 304 are provided below the upper mold 302, and a stamping plate 305 is provided below the second guide pillars 304; multiple perforated pillars 306 are provided below the upper mold 302; multiple perforated slots 307 are provided through the stamping plate 305, and the perforated slots 307 correspond to the perforated pillars 306; multiple unloading slots 308 are provided on the lower mold 303, and the unloading slots 308 correspond to the perforated slots 307; The front and rear ends of the stamping plate 305 are provided with cutting blocks 309 fixedly connected to the upper die 302; when the upper die 302 and the lower die 303 are separated, the lower end face of the stamping plate 305 is lower than the lower end face of the cutting block 309; the feeding end of the lower die 303 is slidably connected with a plurality of third guide posts 310, and a lifting block 311 is fixedly connected above the third guide posts 310, the lifting block 311 being located below the cutting block 309 at the feeding end; the cutting block 309 is located at the discharge end. 9 extends beyond the upper end face of the lower mold 303; the third guide post 310 is surrounded by a first spring 312; as the cutting block 309 is pressed, the lifting block 311 will descend accordingly, and the cut end of the material will be placed on the lifting block 311. After the cutting block 309 cuts, it rises, and under the action of the first spring 312, the lifting block 311 rises and drives the end of the material to be flush with the upper plane of the lower mold 303 again, thereby ensuring that the material can smoothly enter the lower mold 303. The stamping mechanism 3 causes the upper die 302 of the processing mold 301 to move up and down through the stamping machine body 300. When the raw material moves to the lower die 303, the stamping machine body 300 causes the upper die 302 to descend. The stamping plate 305 first contacts the raw material and flattens it. As the upper die 302 continues to descend, the punching column 306 passes through the punching groove 307 downward. The waste generated by punching falls into the lower die 303 through the unloading groove 308. At the same time, the cutting blocks 309 at both ends divide the raw material into segments to form a substrate. Then the upper die 302 rises and the raw material continues to move forward a certain distance, pushing the already cut substrate into the conveying mechanism 4. At the same time, unprocessed raw material enters the lower die 303. The upper die 302 descends again to cut, and the process is repeated.

[0032] Conveying mechanism 4 is located at the discharge end of stamping mechanism 3; for example... Figure 6As shown, the conveying mechanism 4 is used to separate and convey the formed license plate substrate and the waste material from the cutting process. The conveying mechanism 4 includes a mounting frame 400, on which a first conveyor belt 401 is mounted. The upper surface of the first conveyor belt 401 is flush with the upper surface of the lower mold 303. There is a gap between the first conveyor belt 401 and the lower mold 303. A third guide roller 402 is mounted on the mounting frame 400 and located in the gap. A second conveyor belt 403 is mounted on the mounting frame 400 and located below the first conveyor belt 401. The feed end of the second conveyor belt 403 is located below the gap. Before being fed into the first conveyor belt 401, the cut substrate passes through the gap. Due to the support of the third guide roller 402, the substrate can smoothly enter the first conveyor belt 401. Because the waste material is small, it will fall from the gap onto the second conveyor belt 403, thus achieving the effect of separating and conveying the substrate by the first conveyor belt 401 and the waste material by the second conveyor belt 403.

[0033] Preferably, such as Figure 2 and Figure 3As shown, the edge grinding mechanism 206 includes a second mounting plate 214 respectively disposed within the mounting side plate 204. The second mounting plate 214 has a second sliding groove 215, and a second mounting seat 216 is disposed above the second sliding groove 215. An edge grinding roller 217 is vertically disposed on the second mounting seat 216. The surface of the edge grinding roller 217 is covered with wear-resistant diamond abrasive material, enabling efficient grinding of the raw material edges. A third bolt 218 is disposed at the upper end of the edge grinding roller 217. The third bolt 218 passes through the edge grinding roller 217, the second mounting seat 216, and the second sliding groove 215, and is threadedly connected to a second limiting plate 219. A third limiting plate 219 is symmetrically disposed on the second platform 200 behind the second mounting plate 214. Mounting plate 220, the third mounting plate 220 has a concave roller 221 and a convex roller 222 rotatably connected on it, the concave roller 221 and the convex roller 222 are engaged with each other; a second guide roller 223 is provided between the second mounting plate 214 and the third mounting plate 220; a first motor 224 is provided on the outer side of the mounting side plate 204 on one side, the output end of the first motor 224 is connected to a first rotating shaft 225, the first rotating shaft 225 is tumbledly connected to the concave roller 221; a first gear 226 is provided on the first rotating shaft 225; the axis of the convex roller 222 passes through the third mounting plate 220 on one side and is connected to a second gear 227, the second gear 227 is connected to the first gear 226 and meshes externally. According to the size of the substrate, the second mounting seats 216 on both sides are moved to adjust the position of the grinding roller 217. After the position of the second mounting seat 216 is determined, the lower end of the third bolt 218 is tightened to pass through the second mounting seat 216 and the second slide groove 215 and connect with the second limiting plate 219. The second bolt 213 is tightened continuously so that the second mounting seat 216 and the second limiting plate 219 are close to the second mounting plate 214 for fixation. After the raw material passes through the grinding roller 217, the two sides of the cut are ground to make it smoother. Then it passes between the concave roller 221 and the convex roller 222. Under the drive of the first motor 224, the first rotating shaft 225 rotates. The first rotating shaft 225 drives the concave roller 221 to rotate and the convex roller 222 rotates through the first gear 226 and the second gear 227, so that the upper and lower parts of the side of the raw material are ground as it passes through.

[0034] Preferably, such as Figure 4As shown, the lower mold 303 has first guide posts 313 at its four corners, and guide sleeves 314 are slidably connected to the upper part of the first guide posts 313. A second spring 315 is provided below the guide sleeves 314 and surrounds the outside of the first guide posts 313. The upper mold 302 has multiple sliding cylinders 316, which are hollow inside and cooperate with the guide sleeves 314. By the sliding cylinders 316 cooperating with the guide sleeves 314 and descending along the first guide posts 313, the upper mold 302 is guided to open and close smoothly and accurately relative to the lower mold 303, preventing deviation and shaking during the movement. When the upper mold 302 and the lower mold 303 need to separate, the second spring 315 provides sufficient elasticity to reset the guide sleeves 314.

[0035] Preferably, such as Figure 4 As shown, mounting blocks 317 are symmetrically arranged on both sides of the feed end of the lower mold 303. Guide wheels 318 are rotatably connected to the outer ends of the mounting blocks 317. The guide wheels 318 are made of wear-resistant rubber, effectively preventing scratches on the surface of the raw material. A fourth bolt 319 is provided on the inner end of the mounting block 317, passing through the mounting block 317 and connected to the lower mold 303 via threads. By adjusting the angle of the mounting blocks 317 on both sides, the distance between the guide wheels 318 is made equal to the width of the raw material. Then, by tightening the fourth bolt 319, the mounting blocks 317 are fixed, ensuring that the edge of the raw material contacts the guide wheels 318 before entering the lower mold 303, guaranteeing that the raw material will not deviate during feeding.

[0036] Preferably, such as Figure 7As shown, the hanging cylinder mechanism 1 includes a second motor 102 disposed on the side of the first platform 100, the output end of the second motor 102 passing through the first platform 100 and connected to the hanging cylinder rod 101; a second rotating shaft 103 is rotatably connected to the platform, and a first rotating frame 104 located on the side of the hanging cylinder rod 101 is disposed on the second rotating shaft 103, and a bonding roller 105 is disposed at the outer end of the first rotating frame 104; a hydraulic cylinder 106 is disposed on the first platform 100, and the extended end of the hydraulic cylinder 106 is rotatably connected to A connecting plate 107 is fixedly connected to the second rotating shaft 103. A fourth guide roller 108 is provided on the upper and lower sides of the first platform 100, located at the discharge end of the hanging rod 101. A blocking plate 109 is provided at the outer end of the hanging rod 101, and the blocking plate 109 is threadedly connected to the hanging rod 101. After the raw material roll is hung on the hanging rod 101, the blocking plate 109 is screwed onto the outer end of the hanging rod 101 to prevent the raw material roll from falling off the end of the hanging rod 101. The raw material roll is hung on the hanging rod 101 of the hanging mechanism 1, and the rotation of the raw material roll is controlled by the rotation of the second motor 102, thereby controlling its discharge speed. The hydraulic cylinder 106 rotates the second rotating shaft 103 through the connecting plate 107, causing the contact roller 105 on the first rotating frame 104 to contact the raw material roll, preventing it from shaking and falling off the hanging rod 101 during rotation.

[0037] Working principle: Raw material feeding and conveying: The raw material roll is hung on the hanging rod 101 of the hanging mechanism 1. The rotation of the hanging rod 101 is controlled by the drive mechanism to adjust the feeding speed. At the same time, the bonding roller 105 on the hanging mechanism 1 abuts against the raw material roll to prevent it from shaking and falling off during rotation. The raw material is then output after being guided by the fourth guide roller 108.

[0038] Rolling and Trimming: The raw material roll output from the hanging cylinder mechanism 1 enters the rolling and trimming mechanism 2. Multiple pairs of flattening rollers 202 roll the raw material flat. According to the substrate width requirements, the first mounting seats 209 on both sides are moved by the blade adjustment mechanism 201 to change the spacing of the cutting blades 203. The raw material passes through the cutting blades 203 to trim both sides. The trimmed raw material passes through the rolling rollers again and then enters the edge grinding mechanism 206. The edge grinding roller 217 grinds the trimmed edges of the raw material. Subsequently, the raw material passes through the mutually mating concave roller 221 and convex roller 222 to achieve fine grinding of the upper and lower parts of the sides.

[0039] Stamping: The polished raw material enters the stamping mechanism 3. The stamping machine body 300 drives the upper die 302 of the processing mold 301 to descend. The stamping plate 305 first flattens the raw material. The upper die 302 continues to descend, and the punching pin 306 punches holes in the raw material through the punching groove 307. The waste material is discharged through the unloading groove 308. At the same time, the cutting blocks 309 at both ends divide the raw material into segments to form substrates. After the upper die 302 rises, the raw material moves forward, and the formed substrate is pushed into the conveying mechanism 4. New raw material enters the lower die 303, and the stamping operation is repeated.

[0040] Separation and conveying: The stamped license plate base plate and waste material enter the conveying mechanism 4. The base plate is guided into the first conveyor belt 401 by the third guide roller 402, while the smaller waste material falls from the gap between the first conveyor belt 401 and the lower die 303 to the second conveyor belt 403 below, thereby realizing the separation and conveying of the base plate and waste material.
