Description

Technical Field

[0001] This application relates to the field of production of ID card holders, and particularly to a waterproof ID card holder production line. Background Art

[0002] As an important tool for identity recognition, the efficiency and quality of the production process of ID card holders directly affect the management order of various places. In the field of ID card holder manufacturing, the popularization of automated production lines has greatly improved production efficiency, reduced labor costs, and also promoted the standardization and refinement of ID card holder manufacturing technology. However, with the continuous growth of market demand, some detailed problems in the production process have gradually emerged, becoming the key factors restricting the further improvement of product quality.

[0003] In the prior art, in order to achieve the automated production of ID card holders, the manufacturing process is usually completed by a multi-process linkage method. Specifically, on the production line, two plastic tapes unrolled from two material rolls are initially overlapped, and then the overlapped plastic tapes are heat-pressed by a hot press to form the basic shape of the ID card holder and achieve edge bonding. Then, a punching machine is used to complete the functional punching operation of the ID card holder, and finally, the finished product is obtained through cutting.

[0004] However, ID card holders are generally made of plastic, and it is easy for ID card holders to generate static electricity and attract dust. When the dust is at the edge where the two material rolls are overlapped and heat-pressed, the dust will reduce the bonding effect between the two material rolls after heat pressing. Summary of the Invention

[0005] In order to reduce the static electricity generated during the production process of ID card holders, this application provides a waterproof ID card holder production line.

[0006] The waterproof ID card holder production line provided by this application adopts the following technical solutions: The waterproof ID card holder production line includes a roller rack, a hot press table, and a punching table arranged in sequence along the process direction. A first material roll and a second material roll are rotatably installed on one side of the roller rack away from the hot press table. Both the first material roll and the second material roll are used for unrolling material rolls. The roller rack is also equipped with an electrostatic elimination mechanism for eliminating static electricity from the material rolls. The hot press table is fixedly installed with a hot press for heat-pressing and bonding the rolled materials unrolled from the first material roll and the second material roll. The punching table is equipped with a punching machine for punching the rolled materials. Two transmission rollers are installed on one side of the punching table away from the hot press table, and the two transmission rollers are used for clamping the material roll. The first material roll, the second material roll, and the transmission rollers are all equipped with driving members for driving the first material roll, the second material roll, and the transmission rollers to rotate.

[0007] By adopting the above technical solution, during the production process of the ID card holder, the static elimination mechanism can effectively remove static electricity, reduce the problem of dust adsorption caused by static electricity, and thus improve the production quality of the ID card holder.

[0008] Optionally, the static elimination mechanism includes a mounting rod, a bamboo mat, and a guiding roller. The mounting rod and the guiding roller are both installed on a roller frame. One side of the bamboo mat is fixedly connected to the mounting rod. The material roll sequentially passes around the bottom side of the mounting rod and the top side of the guiding roller and then enters the hot press. The side of the bamboo mat away from the mounting rod is bent and abuts against the material roll.

[0009] By adopting the above technical solution, the bamboo mat contacts the material roll for conduction, thereby reducing the static electricity on the surface of the material roll, reducing the problem of dust adhesion caused by static adsorption, and further improving the cleanliness and overall quality of the ID card holder product. In addition, the weight of the bamboo mat presses on the material roll, which facilitates the tensioning of the material roll.

[0010] Optionally, a pressing plate is arranged on the top side of the hot press table. The pressing plate is located on the side of the hot press close to the roller frame. Guide rods are arranged on both sides of the pressing plate. One end of the guide rod is fixedly connected to the top side of the hot press table, and the other end of the guide rod slidably penetrates through the pressing plate. The pressing plate is used to flatten the material roll. A first chute is formed on the top side of the hot press table, and two first sliders are slidably arranged inside the first chute. A limiting rod is fixedly installed on the top side of the first slider, and the pressing plate is provided with a sliding opening for the limiting rod to slidably pass through.

[0011] By adopting the above technical solution, the pressing plate can flatten the material roll, effectively avoiding the problem of poor bonding caused by wrinkles during the hot pressing process of the material roll, and thus improving the production quality of the ID card holder. The setting of the guide rods is used to limit the material roll, thereby reducing the occurrence of the situation where the material roll is inclined. The cooperation between the limiting rod and the first slider facilitates adjusting the position according to the width of the material roll, enhancing the adaptability of the equipment.

[0012] Optionally, a second chute is formed on the top side of the punching table. The second chute is located between the punching machine and the transmission roller. Two second sliders are slidably arranged inside the second chute. A first cutting knife is fixedly installed on the top side of the second slider. The first cutting knife is used to cut both sides of the material roll. A winding roller is rotatably installed on the bottom side of the punching table. The winding roller is also provided with a driving member, and the driving member is used to drive the winding roller to rotate. The winding roller is used to wind up the waste generated after the first cutting knife cuts the material roll.

[0013] By adopting the above technical solution, the width of the material roll is generally larger than the size of the name card holder. The first cutting knife can cut both sides of the material roll, thus facilitating the removal of the waste materials on both sides of the material roll and further facilitating the production of name card holders. At the same time, the winding roller rotatably installed on the bottom side of the punching table is driven to rotate by a driving member, which can effectively wind the waste materials generated after the first cutting knife cuts, thereby keeping the production environment clean and improving production efficiency.

[0014] Optionally, the speed of the winding roller for winding the waste materials is faster than the speed of the conveying roller for conveying the material roll.

[0015] By adopting the above technical solution, the winding roller first pulls the material roll to move, thereby reducing the resistance of the conveying roller for conveying the material roll, and further reducing the occurrence of slipping between the conveying roller and the material roll.

[0016] Optionally, a material receiving box is arranged on one side of the punching table away from the hot pressing table. The top side of the material receiving box is open. A guiding trough body is fixedly installed on the top side of the material receiving box. The guiding trough body is arranged vertically. The material roll conveyed by the conveying roller enters the inside of the guiding trough body, and the material roll abuts against the inner bottom wall of the guiding trough body. A cutting mechanism is fixedly installed on the guiding trough body, and the cutting mechanism is used for cutting the material roll to form a name card holder.

[0017] By adopting the above technical solution, the cutting mechanism can directly cut the material roll to form a name card holder, thereby effectively reducing the subsequent processes that need to be manually operated, improving production efficiency and reducing labor costs.

[0018] Optionally, the cutting mechanism includes a cylinder, a mounting plate, a screw rod, a first nut and a second cutting knife. The cylinder body of the cylinder is fixedly installed on the side of the guiding trough body away from the punching table. The piston rod of the cylinder is fixedly connected with the mounting plate. The cylinder is used to drive the mounting plate to approach or move away from the inner bottom wall of the guiding trough body. An installation groove is formed on the side of the mounting plate away from the cylinder. The end of the screw rod is fixedly inserted into the inner side wall of the installation groove. The screw rod slidably penetrates through the second cutting knife. Two first nuts are correspondingly arranged on the second cutting knife. The first nuts are threadedly sleeved on the screw rod, and the two first nuts are used to clamp the second cutting knife.

[0019] By adopting the above technical solution, the first nut can effectively limit the position of the second cutting knife on the screw rod, prevent it from sliding unnecessarily, and at the same time facilitate the flexible adjustment of the position of the second cutting knife according to actual needs, so as to meet the production requirements of name card holders of different sizes.

[0020] Optionally, the screw rod is provided with a mounting block. The screw rod slidably penetrates through the mounting block. The mounting block is located below the second cutter. One side of the mounting block away from the cylinder is hinged with a connecting frame. A torsion spring is installed at the hinge between the connecting frame and the mounting block. The torsion spring is used to make the connecting frame gradually decrease from one end close to the mounting block to the other end and be inclined. A pressure roller is rotatably installed on the side of the connecting frame away from the mounting block.

[0021] By adopting the above technical solution, the hinge between the mounting block and the connecting frame and the action of the torsion spring make the connecting frame inclined. Thus, during the conveying process of the material roll, the pressure roller can apply a certain pressure to the material roll to ensure that the material roll is conveyed to the cutting position smoothly and stably. The rotatable installation method of the pressure roller reduces the frictional resistance with the material roll and improves the smoothness of the material roll conveying. In addition, the structure is simple and reliable, effectively improving the production quality of the name tag holder.

[0022] Optionally, a telescopic cylinder is fixedly installed on one side of the material guiding trough body close to the punching table. One end of the telescopic cylinder is flush with the inner bottom wall of the material guiding trough body. A pressure sensor is fixedly installed at the end of the telescopic cylinder away from the material guiding trough body. A push rod is telescopically arranged inside the telescopic cylinder. A spring is fixedly installed between one end of the push rod and the pressure sensor. The other end of the push rod is hemispherical. The spring is used to drive the end of the push rod away from the pressure sensor into the interior of the material guiding trough body.

[0023] By adopting the above technical solution, when the material roll deviates inside the material guiding trough body, the material roll will squeeze the push rod, causing the push rod to retract into the telescopic cylinder. During the retraction process of the push rod, the spring is compressed and acts on the pressure sensor, generating a pressure change signal. By analyzing the pressure change detected by the pressure sensor, it is possible to timely judge whether the material roll deviates, thus effectively avoiding product quality problems caused by the position deviation of the material roll.

[0024] Optionally, the cross-sections at both ends of the screw rod are rectangular.

[0025] By adopting the above technical solution, the design of the rectangular cross-sections at both ends of the screw rod can effectively prevent the screw rod from rotating in the installation groove, thereby ensuring the stability of the connection between the screw rod and the installation groove.

[0026] In summary, the present application includes at least one of the following beneficial technical effects: 1. By providing an electrostatic elimination mechanism on the roller rack, the static electricity generated during the unwinding and transmission of the material roll is effectively removed, avoiding the plastic tape from adsorbing dust, and significantly improving the surface cleanliness and overall aesthetics of the name tag holder; 2. The pressing flat plate on the hot pressing table can flatten the material roll, reduce the wrinkles or offsets of the material during the hot pressing process, and improve the accuracy and quality of the hot pressing bonding; 3. The first cutting knife provided on the punching table and the winding roller are used in cooperation to efficiently cut off the waste materials on both sides of the material roll and recycle them, optimize the production process, and reduce the difficulty of waste material treatment.

Detailed Description of the Embodiments

[0029] The following Figures 1-9 further describes the present application in detail with reference to the

[0030] Embodiment 1.

[0031] The embodiment of the present application discloses a waterproof chest card holder production line.

[0032] Refer to Figure 1 andFigure 2 , a waterproof name card holder production line, including a roller rack 1, a hot press table 2 and a punching table 3 arranged in sequence along the process direction. On one side of the roller rack 1 away from the hot press table 2, a first material roller 4 and a second material roller 5 are rotatably installed. Both the first material roller 4 and the second material roller 5 are equipped with a driving member 6, and the driving member 6 is used to drive the first material roller 4 and the second material roller 5 to rotate and unwind the material roll. In the embodiment of the present application, the driving member 6 is a motor. The roller rack 1 is also equipped with an electrostatic elimination mechanism 7 for performing electrostatic elimination treatment on the material roll.

[0033] Refer to Figure 2 , one electrostatic elimination mechanism 7 is respectively provided corresponding to the first material roller 4 and the second material roller 5. The electrostatic elimination mechanism 7 includes a mounting rod 71, a bamboo mat 72 and a guide roller 73. In another embodiment, the electrostatic elimination mechanism 7 can also use an ion blower. The mounting rod 71 is fixedly installed on the roller rack 1, and the guide roller 73 is rotatably installed on the roller rack 1. One side of the bamboo mat 72 is fixedly connected to the mounting rod 71. The material roll passes through the bottom side of the mounting rod 71 and the top side of the guide roller 73 in sequence and then enters the next process. The side of the bamboo mat 72 away from the mounting rod 71 is bent and abuts against the material roll. The static electricity on the material roll is released through the bamboo mat 72, thus playing the role of electrostatic elimination. At the same time, the weight of the bamboo mat 72 presses down on the material roll, thus facilitating the straightening of the material roll.

[0034] Refer to Figure 3 , Figure 4 , on the top side of the hot press table 2, a pressing flat plate 8 is provided. Guide rods 9 are provided on both sides of the pressing flat plate 8. One end of the guide rod 9 is fixedly connected to the top side of the hot press table 2, and the other end of the guide rod 9 slidably penetrates through the pressing flat plate 8. The material rolls unwound from the first material roller 4 and the second material roller 5 are stacked and pass under the pressing flat plate 8, and the pressing flat plate 8 flattens the two material rolls to reduce wrinkles.

[0035] Refer to Figure 3 , Figure 4 , on the top side of the hot press table 2, a first chute 10 is opened. Two first sliders 11 are slidably arranged inside the first chute 10. The two first sliders 11 have damping inside the first chute 10 and cannot slide, and the position of the first slider 11 inside the first chute 10 is adjusted by means of plugging and unplugging. The top side of the first slider 11 is fixedly installed with a limiting rod 12, and the pressing flat plate 8 is provided with a sliding opening 13 for the limiting rod 12 to slidably penetrate through. After pulling out the first slider 11 from the first chute 10 according to the position of the material roll and then reinserting it, the limiting rod 12 is made to abut against both sides of the material roll for limiting, so as to reduce the occurrence of the situation of the material roll offset. A hot press 14 is fixedly installed on the top side of the hot press table 2, and the hot press 14 is located on the side of the pressing flat plate 8 away from the roller rack 1. The hot press 14 is used to perform hot pressing and bonding on the rolled materials unwound from the first material roller 4 and the second material roller 5.

[0036] Refer to Figure 5 , Figure 6, a punching machine 15 is fixedly installed on the top side of the punching table 3, and the punching machine 15 is used for punching the coil material. On one side of the punching table 3 away from the hot pressing table 2, two transmission rollers 16 are installed. The coiled material punched by the punching machine 15 passes between the two transmission rollers 16, and the two transmission rollers 16 clamp the coiled material. The transmission roller 16 is also equipped with a driving member 6, and the driving member 6 is used to drive the transmission roller 16 to rotate, so as to facilitate the conveying of the coiled material.

[0037] Refer to Figure 5 , Figure 6 , a second chute 17 is opened on the top side of the punching table, and the second chute 17 is located between the punching machine and the transmission roller 16. Two second sliders 18 are slidably arranged inside the second chute 17. The two second sliders 18 have damping and cannot slide inside the second chute 17, and the position of the second slider 18 inside the second chute 17 is adjusted by plugging and unplugging.

[0038] Refer to Figure 1 , Figure 6 , a first cutting knife 19 is fixedly installed on the top side of the second slider 18, and a winding roller 20 is rotatably installed on the bottom side of the punching table 3. The winding roller 20 is also provided with a driving member 6. The driving member 6 is used to drive the winding roller 20 to rotate.

[0039] The dimension of the coiled material in the width direction is generally larger than that of the chest card sleeve. According to the position of the coiled material, the position of the second cutting knife 235 is adjusted so that the second cutting knife 235 can cut both sides of the coiled material. After the second cutting knife 235 cuts the coiled material, waste is generated, and the driving member 6 drives the winding roller 20 to wind, so as to effectively reduce the subsequent processes that require manual operation, improve production efficiency and reduce labor costs.

[0040] The implementation principle of the waterproof chest card sleeve production line in the embodiment of the present application is as follows: by setting an electrostatic elimination mechanism 7 on the roller rack 1, using the bamboo mat 72 to reduce the static electricity on the surface of the coiled material, reducing the problem of dust adsorption caused by static electricity, so as to improve the production quality of the chest card sleeve. The design of the pressing plate 8 can ensure that the coiled material remains flat before entering the hot press 14, avoiding poor hot pressing caused by wrinkles. The setting of the cutting knife and the winding roller 20 can cut the coiled material in time and collect waste, so as to effectively reduce the subsequent processes that require manual operation, improve production efficiency and reduce labor costs.

[0041] Embodiment 2.

[0042] The embodiment of the present application discloses a waterproof chest card sleeve production line.

[0043] Refer to Figure 7, the difference between the waterproof ID card holder production line of the embodiment of the present application and that of Embodiment 1 is that a material receiving box 21 is arranged on the side of the punching table 3 away from the hot pressing table 2, and the top side of the material receiving box 21 is open. A material guiding groove body 22 is fixedly installed on the top side of the material receiving box 21, and the material guiding groove body 22 is arranged vertically. The material roll conveyed by the transmission roller 16 falls downward and enters the inside of the material guiding groove body 22, and the material roll abuts against the inner bottom wall of the material guiding groove body 22.

[0044] Refer to Figure 8 , Figure 9 , a cutting mechanism 23 is arranged on the material guiding groove body 22. The cutting mechanism 23 includes a cylinder 231, a mounting plate 232, a screw rod 233, a first nut 234 and a second cutting knife 235. The cylinder body of the cylinder 231 is fixedly installed on the side of the material guiding groove body 22 away from the punching table 3, and the piston rod of the cylinder 231 is fixedly connected with the mounting plate 232. The cylinder 231 is used to drive the mounting plate 232 to approach or move away from the inner bottom wall of the material guiding groove body 22 in the horizontal direction. An installation groove 24 is formed on the side of the mounting plate 232 away from the cylinder 231. The cross sections of both ends of the screw rod 233 are rectangular, and the ends of the screw rod 233 are inserted into the inner side walls of the installation groove 24. The cross section of the end of the screw rod 233 is rectangular and is inserted into the inner side wall of the installation groove 24, so as to play a role in restricting the rotation of the screw rod 233.

[0045] The screw rod 233 slidably penetrates through the second cutting knife 235, and the second cutting knife 235 abuts against the inner bottom wall of the installation groove 24, so as to play a role in restricting the rotation of the second cutting knife 235 around the screw rod 233. Two first nuts 234 are correspondingly arranged on the second cutting knife 235, and the first nuts 234 are threadedly sleeved on the screw rod 233. The two first nuts 234 are used to clamp the second cutting knife 235.

[0046] After two material rolls are stacked for hot pressing and punching and then enter the inside of the material guiding groove body 22, the cylinder 231 is started to drive the mounting plate 232 to move towards the inner bottom wall of the material guiding groove body 22, so that the second cutting knife 235 cuts to form an ID card holder. By cutting with the second cutting knife 235, the subsequent processes that need to be manually operated are effectively reduced, the production efficiency is improved and the labor cost is reduced.

[0047] Refer to Figure 9 , an installation block 25 is arranged on the screw rod 233, and the screw rod 233 slidably penetrates through the installation block 25. The installation block 25 abuts against the inner bottom wall of the installation groove 24, so as to play a role in restricting the rotation of the installation block 25 around the screw rod 233. The installation block 25 is located below each second cutting knife 235. A connecting frame 26 is hinged on the side of the installation block 25 away from the cylinder 231. A torsion spring 27 is installed at the hinge between the connecting frame 26 and the installation block 25. The torsion spring 27 is used to make the connecting frame 26 gradually decrease from the end close to the installation block 25 to the other end and be inclined. A pressing roller 32 is rotatably installed on the side of the connecting frame 26 away from the installation block 25.

[0048] Before the second cutting knife 235 cuts the material roll to form the chest card sleeve, the pressure roller 32 will first press the material roll tightly against the inner bottom wall of the material guiding groove body 22. Due to the reaction force, the connecting frame 26 rotates downward and the pressure roller 32 moves downward. During the downward movement of the pressure roller 32, the pressure roller 32 drives the material roll to flatten, thereby improving the production quality of the chest card sleeve.

[0049] Refer to Figure 8 、 Figure 9 As shown in

[0050] On one side of the material guiding groove body 22 close to the punching table 3, a telescopic cylinder 28 is fixedly installed. One end of the telescopic cylinder 28 is flush with the inner bottom wall of the material guiding groove body 22. A pressure sensor 29 is fixedly installed at the end of the telescopic cylinder 28 away from the material guiding groove body 22. A ejector rod 30 is telescopically arranged inside the telescopic cylinder 28. A spring 31 is fixedly installed between one end of the ejector rod 30 and the pressure sensor 29. The other end of the ejector rod 30 is hemispherical. The spring 31 is used to drive the end of the ejector rod 30 away from the pressure sensor 29 into the interior of the material guiding groove body 22.

[0051] After two stacked material rolls are punched by the punching machine, holes will be left on the material rolls. When the material roll droops and abuts against the inner bottom wall of the material guiding groove body 22, the spring 31 drives the ejector rod 30 to pass through the holes of the material roll, and the pressure received by the pressure sensor 29 decreases. When the material roll deviates, the material roll blocks the ejector rod 30, so that the ejector rod 30 squeezes the spring 31 and moves toward the pressure sensor 29, and the pressure received by the pressure sensor 29 increases. By the magnitude of the pressure received by the pressure sensor 29, it is convenient to judge whether the material roll is placed neatly inside the material guiding groove body 22.

[0052] In the embodiment of the present application, the pressure sensor 29 is electrically connected to a controller. The pressure sensor 29 generates a pressure signal according to the received pressure and sends it to the controller. The controller compares the pressure signal with a preset pressure threshold to judge whether the material roll is placed neatly inside the material guiding groove body 22. When the material roll deviates inside the material guiding groove body 22, the controller can issue an alarm or stop the sleeve production line.

[0053] Embodiment 3.

[0054] The embodiments of this application disclose a production line for waterproof ID card holders.

[0055] Referring to Figure 1 and Figure 6 , the difference between the production line for waterproof ID card holders in the embodiments of this application and that in Embodiment 1 is that the speed of the winding roller 20 for winding waste is faster than the speed of the conveying roller 16 for conveying the material roll. In another embodiment, the speed of the winding roller 20 for winding waste is the same as the speed of the conveying roller 16 for conveying the material roll, but the winding roller 20 starts first and the conveying roller 16 starts later.

[0056] The implementation principle of the production line for waterproof ID card holders in the embodiments of this application is as follows: The winding roller 20 winds the waste to drive the material roll to be conveyed in advance, thereby reducing the resistance of the conveying roller 16 for conveying the material roll, and further reducing the occurrence of slipping when the conveying roller 16 conveys the material roll.

[0057] The above are all the preferred embodiments of this application. Without limiting the protection scope of this application accordingly, therefore: All equivalent changes made according to the structure, shape, and principle of this application shall be covered within the protection scope of this application.
