Description

Technical Field

[0001] This utility model relates to the field of PVC smart card production technology, specifically a polishing and deburring device for PVC smart card production. Background Technology

[0002] With the rapid development of information technology, PVC smart cards have been widely used in many fields such as identity recognition, financial payment, and public transportation due to their convenience and multifunctionality. In the production process of PVC smart cards, cutting, stamping and other processing steps will inevitably produce burrs, rough edges and unevenness on the edges and surface of the cards. These defects not only affect the appearance quality of the cards and reduce the product grade, but may also scratch users during use, and even affect the normal operation of functional components such as chips and magnetic stripes, leading to problems such as abnormal reading and writing, seriously affecting the performance and security of the products.

[0003] Currently, the polishing and deburring of PVC smart cards mostly employs manual grinding or traditional mechanical polishing methods. Manual grinding is inefficient, labor-intensive, and susceptible to variations in worker skill and work conditions, making it difficult to guarantee product quality.

[0004] According to the description in the patent announcement (CN222222222U) of an intelligent card milling groove polishing and deburring mechanism, the intelligent card milling groove polishing and deburring mechanism includes a "processing box, ultrasonic generator" and other components to achieve deburring.

[0005] Regarding the above description, the applicant believes the following issues exist:

[0006] This smart card milling, polishing, and deburring mechanism utilizes a processing box and an ultrasonic generator to perform deburring. During use, all smart cards requiring deburring are placed in a placement frame and immersed in cleaning fluid. Deburring is then performed using the ultrasonic generator. However, when all cards are in the placement frame, the milling grooves on the inner layers of cards may be obstructed, making it difficult for ultrasonic bubbles to fully reach the deep crevices, resulting in incomplete polishing and deburring, especially in complex structures such as narrow or deep grooves. Therefore, improvements to this mechanism are necessary. Utility Model Content

The slide rod is slidably connected inside the sealing box, so that the sealing strip can play a sealing role at the sealing door.

[0012] Preferably, the sealed box has a groove inside, the water reservoir is slidably connected in the groove, a sealing plate is fixedly connected to the outside of the water reservoir, the sealing plate is slidably connected to the top of the sealed box and is located at the top of the groove, and the second nozzle is inclined, so that the top of the groove can be sealed by the sealing plate without affecting the left and right movement of the water reservoir.

[0013] Preferably, the conveying assembly includes a load-bearing frame, which is fixedly connected to the top of the support platform. A water tank is fixedly connected to the top of the load-bearing frame. A conveying pipe is fixedly connected to the right side of the water tank.

[0017] Compared with the prior art, this utility model provides a polishing and deburring device for PVC smart card production, which has the following beneficial effects:

[0018] 1. This polishing and deburring device for PVC smart card production utilizes a polishing mechanism. When polishing burrs on the surface of a PVC smart card is required, a cylinder drives a clamping plate to hold the card in place. A hydraulic cylinder, in conjunction with the hydraulic cylinder, moves the water reservoir and nozzles left and right, achieving stable and precise polishing. The multi-directional first nozzle and the inclined second nozzle can rinse and polish the smart card surface from different angles, effectively removing burrs, improving polishing efficiency and quality, and ensuring the smoothness and gloss of the product surface. The combination of a high-pressure pump and an overflow valve stably controls the water supply pressure and flow rate, ensuring continuous and efficient polishing. The sealed box and sealing strip design, along with a rotatable sealing door, effectively prevents debris and liquid splashing during polishing, creating a closed working environment that ensures operator safety and reduces pollution. Since most smart cards are made of PVC, whose burrs are relatively soft, high-pressure water can achieve the desired polishing effect without damaging the card. When polishing the other side of the card is required, the operator simply needs to manually flip the card, making operation convenient.

[0019] 2. This polishing and deburring device for PVC smart card production, through its set recycling mechanism, allows the recycling tank and the bottom recycling box to form a continuous recycling channel when polishing the burrs on the surface of the PVC smart card under the action of the first and second nozzles. This enables the polishing debris and wastewater to flow quickly into the recycling box. The internal sliding filter frame is securely installed and easily disassembled through a threaded fixed shaft, facilitating centralized cleaning and filtration of debris. The drain pipe facilitates the discharge and subsequent filtration of wastewater for reuse, effectively improving resource utilization. Attached Figure Description

[0031] This utility model provides the following technical solution:

[0032] Example 1

[0033] Please see Figure 1-7 This utility model provides a technical solution: a polishing and deburring device for PVC smart card production, including a base 1, a polishing mechanism 2 at the top of the base 1, and a recycling mechanism 3 at the bottom of the polishing mechanism 2.

[0034] The polishing mechanism 2 includes a polishing component 21 and a conveying component 22. The polishing component 21 is disposed on the top of the base 1, and the conveying component 22 is disposed on the top of the polishing component 21.

[0036] The sealing strip 219 is located on the top of the support platform 211 and is in contact with the rear side of the sealing door 214. The support platform 211 has a recycling groove inside, and the recycling groove is rectangular. The slide rod 217 is slidably connected inside the sealing box 212, so that the sealing strip 219 can seal the sealing door 214.

[0037] The sealed box 212 has a sliding groove inside, and the water reservoir 2192 is slidably connected in the sliding groove. A sealing plate 2193 is fixedly connected to the outside of the water reservoir 2192. The sealing plate 2193 is slidably connected to the top of the sealed box 212 and is located at the top of the sliding groove. The second nozzle 2196 is inclined so that the top of the sliding groove can be sealed by the sealing plate 2193 without affecting the left and right movement of the water reservoir 2192.

[0038] Please see Figure 1-7This utility model provides a technical solution: the conveying component 22 includes a load-bearing frame 221, which is fixedly connected to the top of the support platform 211.

[0039] Example 2

[0040] Please see Figure 1-7 Furthermore, based on Embodiment 1, the recycling mechanism 3 further includes a recycling box 31, which is fixedly connected to the bottom of the support platform 211. A filter frame 32 is slidably connected inside the recycling box 31, and a fixed shaft 33 is threadedly connected inside the filter frame 32. A drain pipe 34 is fixedly connected to the bottom of the recycling box 31, and the fixed shaft 33 passes through the inside of the recycling box 31.

[0041] In actual operation, when this device is used to polish the burrs on the surface of a PVC smart card, the card is first placed in the middle of the top of the support platform 211, inside the clamping plate 218. The cylinder 213 drives the clamping plate 218 to clamp the PVC smart card. When the clamping plate 218 moves, it will drive the slide rod 217 to slide inside the sealed box 212, which can ensure the stability of the card. At this time, the sealing door 214 is closed. The design of the sealing box 212 and the sealing strip 219, together with the rotatable sealing door 214, effectively prevents the debris and liquid splashing generated during the polishing process, creating a closed working environment, which not only ensures the safety of the operator, but also reduces the pollution to the working environment.

[0042] After fixing, the combination of high-pressure pump 223 and overflow valve 224 can deliver clean water to water tank 222, stably controlling the water supply pressure and flow rate to ensure continuous and efficient polishing. Clean water is delivered to water reservoir 2192 and sprayed out through first nozzle 2195 and second nozzle 2196, simultaneously polishing the surface and front and back sides of the card. During polishing, hydraulic cylinder 215 drives the connecting arm 2191 and water reservoir 2192 to move. Furthermore, by allowing the water reservoir 2192 to slide around the fixed rod 2194, the left and right positions of the first nozzle 2195 and the second nozzle 2196 can be changed to achieve full polishing. When the water reservoir 2192 moves, it will drive the sealing plate 2193 to move. The sealing plate 2193 is located at the top of the slide groove, which can ensure the sealing of the top of the sealing box 212 without affecting the movement of the water reservoir 2192. When the water reservoir 2192 moves, it will also drive the hose 226 to slide within the connecting frame 225 to ensure the normal delivery of water.

[0043] The recycling tank and the bottom recycling box 31 form a continuous recycling channel, allowing polishing debris and wastewater to flow quickly into the recycling box 31. The internal sliding filter frame 32 is securely installed and easily disassembled through a threaded fixed shaft 33, facilitating centralized cleaning of debris and solid-liquid separation of wastewater. The drain pipe 34 is connected to the external recycling pipe, which facilitates wastewater discharge and subsequent filtration treatment for reuse, effectively improving resource utilization.

[0044] When it is necessary to polish the other side of the card, simply release the clamp 218 from the card's position, and the staff can manually flip the card to fix it again. The operation is convenient and will not affect the polishing efficiency. Most smart cards are made of PVC material, and their burrs are relatively soft. High-pressure water jets can achieve the polishing effect without damaging the card.

[0045] In use, the cylinders 213, hydraulic cylinders 215 and high-pressure pumps 223 on both sides can be connected to the same PLC control system to ensure coordinated and synchronous operation between the equipment. The PLC control system is existing technology, and those skilled in the art are well aware of the specific operating steps of this system. This case will not describe it in detail. In addition, the sealing door 214 in this case is transparent.
