Abstract
Description
Technical Field
[0001] This invention relates to the field of gold-colored imitation metal PET sheet production technology, and in particular to a non-electroplated gold-colored imitation metal PET sheet continuous molding production line. Background Technology
[0002] The core of manufacturing non-electroplated gold-plated imitation metal PET sheets is to form a thin film layer with a gold metallic texture on the surface of the PET substrate through coating or vacuum physical coating processes. However, the surface of PET sheets (usually extruded transparent / semi-transparent rolls with a thickness of 0.05-0.5mm) is smooth and has residual mold release agent. Direct coating / coating is prone to insufficient adhesion and peeling problems. Therefore, the surface of the PET sheet needs to be cleaned before coating.
[0003] The existing method for cleaning the surface of PET sheets involves cleaning the extruded PET sheets in a cleaning tank, followed by drying and coating. However, existing drying devices mostly use hot air drying or infrared heating at a fixed temperature, which lacks the ability to dynamically adapt to changes in the humidity of the substrate. After cleaning, the substrate will carry a certain amount of cleaning agent, and its weight (humidity) will gradually decrease during the drying process. The continuous high temperature of the fixed heat source can easily cause local overheating of the substrate, leading to deformation, yellowing of the PET substrate, and even damage to the internal structure of the substrate, affecting the accuracy of subsequent processing. At the same time, it is difficult to remove the metal dust on the surface of the PET substrate when cleaning it in a cleaning tank.
[0004] Therefore, this application provides a non-electroplated gold-plated imitation metal PET sheet continuous molding production line to meet the demand. Summary of the Invention
[0005] The technical problem to be solved by this invention is to provide a continuous molding production line for non-electroplated gold-plated imitation metal PET sheets. By setting up an adaptive drying device and a wind generator, the plasma wind generated by the wind generator mixes with the external airflow and blows it onto the heated metal mesh to dry the cleaning agent on the substrate surface. At the same time, during the drying process, the adaptive drying device can dynamically match the drying heat with the substrate humidity, preventing high temperature damage to the substrate surface and improving the processing accuracy of the final product. Meanwhile, the positive and negative charges inside the mixed airflow neutralize the charged metal dust on the substrate surface, remove static electricity from the substrate surface, and blow off the metal dust. This solves the problems of existing drying devices easily damaging the substrate surface during the drying process and the difficulty in removing metal dust from the PET substrate surface during cleaning in the washing tank.

The bottom of the two sets of limiting sliding columns on the same side is fixedly installed with the same clamping seat 2. A spring is sleeved on the limiting sliding column, and one end of the spring is fixedly connected to the bottom of the material support platform, and the other end of the spring is fixedly connected to the clamping seat 1.
[0008] Optionally, guide columns are fixedly installed on both end walls of the support frame, and slide rails are slidably installed on two sets of guide columns on the same side. A clamping frame is provided inside the support frame, and inserts are fixedly installed on both sides of the clamping frame, with the inserts plugging into the corresponding slide rails. The clamping seat is slidably connected to the corresponding slide rail. A metal mesh is fixedly installed on the inner wall of the middle of the clamping frame, and the clamping frame is made of non-metallic material.
[0009] Optionally, a screw is rotatably mounted on the left outer wall of the support frame, and the left clamp engages with the screw. A motor is fixedly mounted on the outer wall of the support frame, and the output end of the motor is fixedly connected to the end wall of the screw.

[0010] Optionally, a loading frame is fixedly installed on the bottom inner wall of the support frame, an eddy current coil is fixedly installed on the top of the loading frame, and multiple sets of magnetic strips are uniformly snapped onto the bottom inner wall of the loading frame. The magnetic strips are made of ferrite powder filled and pressed.
[0011] Optionally, the wind power generating device includes a sealing cover, the top of which is sealed and connected to the inner wall of the bottom of the support frame, a negative pressure fan is fixedly installed on the inner wall of the outer port of the sealing cover, a dust cover is fixedly installed on the outer wall of the outer port of the sealing cover, a wind-gathering shell is fixedly installed on the inner wall of the bottom of the sealing cover, and a suction zone is formed between the bottom of the wind-gathering shell and the sealing cover, a plasma emitting end is fixedly installed on the inner wall of the bottom of the wind-gathering shell, and a plasma receiving end is fixedly installed on the inner wall of the middle part of the wind-gathering shell, and the plasma emitting end can generate plasma wind at the plasma receiving end.
[0012] Optionally, the end wall of the cleaning chamber is fixedly connected to the side wall of the processing chamber, and brackets are fixedly installed on both sides of the top of the end of the cleaning chamber.

The output end of the cylinder is rotatably connected to a clamping ring, and the clamping ring is sleeved on the corresponding end wall of the tension roller.
[0013] Compared with the prior art, the present invention has at least the following beneficial effects:
[0014] In the above scheme, by setting up an adaptive drying device, alternating current is passed through the eddy current coil, which generates an alternating magnetic field around the eddy current coil. Under the action of the alternating magnetic field, the magnetic flux through the metal mesh changes continuously. Based on the eddy current effect, heat is generated on the surface of the metal mesh. Then, the generated heat is blown onto the surface of the substrate by a wind generator, so that the surface of the substrate is dried. During the drying process of the substrate surface cleaning agent, the overall weight of the substrate will gradually decrease, which will reduce the pressure on the spring. Under the action of the spring restoring force, the material support platform will move the metal mesh away from the eddy current coil, which will reduce the heat generated on the metal mesh. This dynamically matches the drying heat with the substrate humidity (weight), prevents the substrate surface from being damaged by high temperature, and improves the processing accuracy of the final product.
[0015] By setting up a wind generator, plasma wind is generated at the plasma receiving end and mixed with external airflow to blow onto the substrate surface to dry the substrate. While the airflow dries the substrate, the positive and negative charges inside the airflow neutralize the charged metal dust on the substrate surface, remove static electricity from the substrate surface, and blow off the metal dust, thus achieving a secondary cleaning effect on the substrate. After the substrate is dried, the driving cylinder drives the clamping ring to press down, thereby pressing down the tensioning roller to tighten the substrate. At the same time, the driving output roller pulls the substrate from the outside, and synchronously drives the motor to move the receiving platform close to the loading roller, thereby tensioning the dried substrate. The tensioned substrate is then pulled to the coating area for coating to form a non-electroplated gold imitation metal PET sheet that meets the requirements. Attached Figure Description

[0020] The following is a detailed description of a non-electroplated gold-plated imitation metal PET sheet continuous molding production line provided by the present invention, with reference to the accompanying drawings and specific embodiments. It should be noted that, to make the embodiments more detailed, the following embodiments are the best and preferred embodiments; those skilled in the art can also use other alternative methods to implement some known technologies; and the accompanying drawings are only for more specific description of the embodiments and are not intended to specifically limit the present invention.
[0021] like Figures 1 to 14As shown, an embodiment of the present invention provides a continuous molding production line for non-electroplated gold-plated imitation metal PET sheets, including a processing chamber 100 and a cleaning chamber 200. The cleaning chamber 200 has a built-in ultrasonic generator. The processing chamber 100 and the cleaning chamber 200 are connected and form the front of the production line. The processing chamber 100 is provided with a dust-free area 101 and an air-supported zone 102. The dust-free area 101 ensures that no dust will be contaminated during the drying of the substrate. The dust-free area 101 is provided with an adaptive drying device 110, and the air-supported zone 102 is provided with a wind generator 110. 50. The wind generator 150 provides an air source for the adaptive drying device 110; the adaptive drying device 110 includes a support frame 111, an output roller 116 rotatably connected to the inner wall of the top end of the support frame 111, a material-feeding roller 117 rotatably mounted on the inner wall of the front end of the support frame 111, a material-discharging roller 220 rotatably mounted on the top of the front end of the cleaning chamber 200, a material-pressing roller 210 rotatably mounted on the inner wall of the middle part of the cleaning chamber 200, and a tensioning roller 231 provided at the top of the end of the cleaning chamber 200. PET film substrate is wound on the material-discharging roller 220. The PET film substrate passes sequentially through the pressure roller 210, tension roller 231, overlap roller 117, and output roller 116. In this invention, the core of manufacturing non-electroplated gold-plated imitation metal PET sheets is to form a thin film layer with a gold metallic texture on the surface of the PET substrate through a coating process or vacuum physical coating process. However, the surface of PET sheets (usually extruded transparent / semi-transparent rolls, 0.05-0.5mm thick) is smooth and has residual mold release agent. Direct coating / coating is prone to insufficient adhesion and peeling problems. Therefore, in the coating process... Before cleaning, the surface of the PET sheet needs to be cleaned. Specifically, pure water and a neutral cleaning agent (such as 0.5% sodium dodecyl sulfate) are added to the cleaning chamber 200. The ultrasonic generator built into the cleaning chamber 200 is then activated to ultrasonically clean the substrate in the cleaning chamber 200 for 10-15 minutes to remove oil, fingerprints, dust and residual mold release agent from the surface of the substrate. At this time, some charged metal dust will still remain on the surface of the substrate. After the substrate in the cleaning chamber 200 is cleaned, the substrate is pulled to move the cleaned substrate into the support frame 111.
[0022] As one implementation method in this embodiment, such as Figure 2 , Figure 4 , Figures 9 to 14As shown, the support frame 111 has inner sliding grooves 112 on both sides of its top. A clamping seat 120 is slidably mounted on the inner sliding groove 112. The top of the two clamping seats 120 is provided with the same material support platform 121. The material support platform 121 can support the substrate (including cleaning agent) and can provide feedback to the spring 123 according to the weight of the substrate. Two sets of limiting sliding pillars 122 are fixedly mounted on both sides of the bottom of the material support platform 121. The two sets of limiting sliding pillars 122 on the same side slide through the clamping seat 120 on that side. The bottom of the two sets of limiting sliding pillars 122 on the same side is fixedly mounted with the same clamping seat 124. A spring 123 is sleeved on the limiting sliding pillar 122, and one end of the spring 123 is fixedly attached to the bottom of the material support platform 121. The spring 123 is fixedly connected to the other end of the clamp 120. Guide posts 118 are fixedly installed on both end walls of the support frame 111. Slide rails 119 are slidably installed on the two sets of guide posts 118 on the same side. A clamping frame 130 is provided inside the support frame 111. Inserts 131 are fixedly installed on both sides of the clamping frame 130, and the inserts 131 are inserted into the corresponding slide rails 119. The clamp 124 is slidably connected to the corresponding slide rail 119. A metal mesh 132 is fixedly installed on the inner wall of the middle part of the clamping frame 130. The clamping frame 130 is made of non-metallic material. A loading frame 140 is fixedly installed on the bottom inner wall of the support frame 111. An eddy current coil 141 is fixedly installed on the top of the loading frame 140. Multiple sets of magnetic strips 142 are evenly clamped onto the inner wall of the bottom of the 0. The magnetic strips 142 are made of ferrite powder and are pressed together. The magnetic strips 142 made of ferrite powder shield the electromagnetic field and can effectively prevent electromagnetic energy from leaking from below the loading frame 140. In this invention, the substrate to be cleaned is located between the receiving platform 121 and the loading roller 117. At this time, the weight of the substrate (containing undried cleaning agent) is entirely borne by the receiving platform 121 and the loading roller 117, thereby compressing the spring 123 and driving the metal mesh 132 to move downward as a whole. The greater the weight of the substrate, the greater the compression of the spring 123 and the greater the downward movement of the metal mesh 132. Then, alternating current is applied to the eddy current coil 141, so that the eddy current coil 141... An alternating magnetic field is generated around the metal mesh 132. Under the influence of this alternating magnetic field, the magnetic flux through the metal mesh 132 changes continuously. Based on the eddy current effect, heat is generated on the surface of the metal mesh 132. At the same time, the plasma wind generated by the wind generator 150 blows the heat generated on the metal mesh 132 toward the substrate being cleaned inside the support frame 111, thereby drying the surface of the substrate. During the drying process of the cleaning agent on the substrate surface, the overall weight of the substrate gradually decreases, which reduces the pressure on the spring 123. Under the action of the restoring force of the spring 123, the support platform 121 will move the metal mesh 132 away from the eddy current coil 141, thereby reducing the heat generated on the metal mesh 132 and preventing the high temperature from damaging the surface of the substrate.
[0023] In this embodiment, as Figure 11 and Figure 13As shown, a screw 113 is rotatably mounted on the left outer wall of the support frame 111, and the clamp 120 on the left side meshes with the screw 113. A motor 115 is fixedly mounted on the outer wall of the support frame 111, and the output end of the motor 115 is fixedly connected to the end wall of the screw 113. A slide rod 114 is fixedly mounted on the right outer wall of the support frame 111, and the clamp 120 on the right side is slidably connected to the slide rod 114. In this invention, after the substrate to be cleaned is transported into the support frame 111, the drive motor 115 drives its output shaft to drive the screw 113 to mesh with the clamp 120. Under the guidance of the slide rod 114, the screw 113 drives the clamp 120 to move to one end of the output roller 116, so that the substrate to be cleaned is located between the receiving platform 121 and the lap roller 117. At this time, the weight of the substrate (including the undried cleaning agent) is completely borne by the receiving platform 121 and the lap roller 117.
[0024] As one implementation method in this embodiment, such as Figures 6 to 8 As shown, the wind power generating device 150 includes a sealing cover 151. The top of the sealing cover 151 is sealed and connected to the inner wall of the bottom of the support frame 111. A negative pressure fan 152 is fixedly installed on the inner wall of the outer port of the sealing cover 151. The negative pressure fan 152 can send external gas into the sealing cover 151. A dust cover 153 is fixedly installed on the outer wall of the outer port of the sealing cover 151. The dust cover 153 can prevent dust from entering the sealing cover 151. A wind-gathering shell 154 is fixedly installed on the inner wall of the bottom of the sealing cover 151. A suction zone 155 is formed between the bottom of the wind-gathering shell 154 and the sealing cover 151. That is, there is a gap between the bottom of the wind-gathering shell 154 and the sealing cover 151. When airflow is generated in the wind-gathering shell 154, a negative pressure can be generated in the suction zone 155, thereby sending the airflow in the sealing cover 151 into the wind-gathering shell 154. The inner wall of the bottom of the wind-gathering shell 154 is fixedly installed with a negative pressure fan 152. The device is equipped with a plasma emitter 156 and a plasma receiver 157 fixedly installed on the inner wall of the middle part of the air-collecting shell 154. The plasma emitter 156 can generate plasma wind on the plasma receiver 157. In this invention, the negative pressure fan 152 is started and high voltage is introduced into the plasma emitter 156. Under the action of the plasma emitter 156, plasma wind (the airflow carries an equal amount of positive and negative charges) can be generated on the plasma receiver 157. At the same time, the plasma wind can form a negative pressure in the air-collecting shell 154, which draws the airflow in the sealing cover 151 into the air-collecting shell 154 and mixes the charged airflow and blows it onto the metal mesh 132. In particular, the positive and negative charges inside the airflow will neutralize the charged metal dust on the surface of the substrate, remove the static electricity on the surface of the substrate, and blow off the metal dust on the surface of the substrate, thereby achieving the effect of secondary cleaning of the substrate.
[0025] In this embodiment, as Figure 4 and Figure 5As shown, the end wall of the cleaning chamber 200 is fixedly connected to the side wall of the processing chamber 100. Brackets 230 are fixedly installed on both sides of the top of the end of the cleaning chamber 200, supporting the brackets 230. The ends of the tension roller 231 are slidably connected to the inner walls of the two sets of brackets 230. Cylinders 232 are rotatably installed on the inner walls of both sides of the cleaning chamber 200. A clamping ring 233 is rotatably connected to the output end of the cylinder 232, and the clamping ring 233 is sleeved on the end wall of the corresponding tension roller 231. In this invention, after the substrate is dried, the cylinder 232 is driven to press down the clamping ring 233, thereby pressing down the tension roller 231 and pressing it against the substrate. Simultaneously, the output roller 116 is driven to pull the substrate from the outside, and the motor 115 is driven to move the receiving platform 121 close to the loading roller 117, thereby tensioning the dried substrate and pulling the tensioned substrate to the coating area for coating, forming a non-electroplated gold-colored imitation metal PET sheet that meets the requirements.
[0026] The working principle of the technical solution provided by this invention is as follows: Pure water and a neutral cleaning agent (such as 0.5% sodium dodecyl sulfate) are added to the cleaning chamber 200, and the extruded film substrate is placed on the feeding roller 220. The substrate is then pulled through the pressure roller 210, tension roller 231, overlap roller 117, support platform 121 and output roller 116 in sequence (see the attached specification). Figure 3As shown in the figure, the ultrasonic generator built into the cleaning chamber 200 (not marked in the figure) is activated to ultrasonically clean the substrate inside the cleaning chamber 200 for 10-15 minutes to remove oil, fingerprints, dust, and residual mold release agent from the substrate surface. At this time, some charged metal dust will still remain on the substrate surface. After the substrate in the cleaning chamber 200 is cleaned, the substrate is pulled to move the cleaned substrate into the support frame 111. At the same time, the drive motor 115 drives its output shaft to drive the screw 113 to mesh with the clamp 120. Under the guidance of the slide rod 114, the screw 113 drives the clamp 120 to move to one end of the output roller 116, so that the cleaned substrate is located between the receiving platform 121 and the loading roller 117. At this time, the substrate (containing undried cleaning agent) is cleaned. The weight is entirely borne by the support platform 121 and the loading roller 117, thereby compressing the spring 123 and causing the metal mesh 132 to move downwards as a whole. The greater the weight of the substrate (containing undried cleaning agent), the greater the compression of the spring 123 and the greater the downward movement of the metal mesh 132. Then, alternating current is applied to the eddy current coil 141, generating an alternating magnetic field around it. Under the influence of this alternating magnetic field, the magnetic flux through the metal mesh 132 continuously changes. Based on the eddy current effect, heat is generated on the surface of the metal mesh 132 (the closer the metal mesh 132 is to the eddy current coil 141, the greater the change in magnetic flux through it, i.e., the higher the heat generated). Simultaneously, the negative pressure fan 152 is activated and blows heat into the plasma emission end 156. When high voltage is applied, plasma wind (carrying equal amounts of positive and negative charges) is generated at the plasma receiving end 157 under the action of the plasma emitting end 156. Simultaneously, the plasma wind creates a negative pressure within the air-collecting shell 154, drawing the airflow from the sealed cover 151 into the air-collecting shell 154. The charged airflow is then mixed and blown towards the metal mesh 132, and the heat generated on the metal mesh 132 is blown onto the cleaned substrate within the support frame 111, thereby drying the substrate surface. During the drying process of the substrate surface cleaning agent, the overall weight of the substrate gradually decreases, reducing the pressure on the spring 123. Under the restoring force of the spring 123, the receiving platform 121 moves the metal mesh 132 away from the eddy current coil 141, causing the metal... The heat generated on the mesh 132 is reduced, preventing the high temperature from damaging the substrate surface. While the airflow dries the substrate, the positive and negative charges inside the airflow neutralize the charged metal dust on the substrate surface, remove static electricity from the substrate surface, and blow off the metal dust, thereby achieving a secondary cleaning of the substrate. After the substrate is dried, the drive cylinder 232 drives the clamping ring 233 to press down, thereby pressing down the tension roller 231 to press the substrate tightly. At the same time, the drive output roller 116 pulls the substrate from the outside, and synchronously drives the motor 115 to move the receiving platform 121 close to the loading roller 117, thereby tensioning the dried substrate and pulling the tensioned substrate to the coating area for coating, forming a non-electroplated gold imitation metal PET sheet that meets the requirements.
