Description

Technical Field

[0001] This utility model relates to the field of membrane production line technology, and in particular to a reflective microbead electrostatic coating production line. Background Technology

[0002] Reflective materials achieve retroreflection by embedding high-refractive-index glass microspheres or microprism structures on the surface of a substrate, utilizing the principle of light refraction and reflection within the microspheres. Among these, glass microsphere-type reflective materials have become the mainstream choice in traffic signs, safety clothing, and other fields due to their stable performance and strong adaptability. Their core technical requirements include: Glass microsphere characteristics: High refractive index, high transparency, low devitrification, and good sphericity. Production process precision: Micron-level coating control, a constant temperature and humidity dust-free environment, and vibration-free equipment are required. Multi-layer composite structure: A typical structure includes a substrate layer, an adhesive layer, a glass microsphere layer, a metal reflective layer (such as an aluminum layer), and a protective layer, each layer requiring precise coating and composite processes. II. Evolution and Breakthroughs in Electrostatic Film Planting Technology Traditional bead planting processes have three major drawbacks: Uneven distribution: Glass microspheres are prone to stacking due to poor flowability or excessive adhesive viscosity, wasting raw materials and reducing reflectivity. Environmental issues: Microspheres flying away pose a production accident risk, and the floating bead phenomenon affects the product's appearance quality. Innovations in electrostatic coating technology include: Surface modification technology: Cationic surfactants are used to reduce the zeta potential of the microspheres, causing them to maintain a constant negative charge in a high-voltage electrostatic field. Electrostatic repulsion prevents bead stacking, resulting in a uniformly distributed single layer. Pneumatic-electrostatic composite process: Hot air is blown into a fluidized bead trough to suspend the microspheres, and electrostatic adsorption is used for directional deposition, achieving precise deposition of the microspheres on the adhesive layer surface. Thermal composite pressing technology: Thermal composite steel rollers and rubber rollers are used for pressing to enhance adhesion. The microprism-type reflective film has a reflectivity 3-5 times higher than that of glass microspheres, but the production process is complex, and currently only international giants such as 3M possess the core technology.

[0003] Traditional reflective film production processes suffer from the following problems: uneven electrostatic bead deposition, lack of precise control of high-voltage electrostatic field leading to inconsistent microbead adsorption density, low lamination efficiency, reliance on manual operation for hot pressing or adhesive lamination which easily generates bubbles or poor adhesion, poor slitting accuracy (the cutting device lacks buffering and guidance, easily causing burrs or width deviations at the film edges), and low automation (the unwinding, rewinding, and lamination processes are scattered and require multiple people to operate in coordination). Therefore, we propose a reflective microbead electrostatic deposition production line to solve these problems. Utility Model Content

[0004] The purpose of this invention is to provide a reflective microbead electrostatic coating production line to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A reflective microbead electrostatic coating production line includes: a processing table, a protective shell fixedly installed on the top of the processing table, an electric push rod fixedly installed on the protective shell, a lower pressure plate fixedly installed at the output end of the electric push rod, an electric plate and multiple corona treatment machines fixedly installed at the bottom end of the lower pressure plate, multiple high-voltage electrostatic generators fixedly installed at the bottom end of the electric plate, two side support plates 1 fixedly installed on one side of the processing table, a feeding roller rotatably installed between the two side support plates 1, two side support plates 2 fixedly installed on the other side of the processing table, a receiving roller rotatably installed between the two side support plates 2, a motor 2 fixedly installed on one of the receiving rollers, the output end of the motor 2 fixedly connected to the receiving roller, a cutting control component and a heating composite component provided at the top of the processing table.

[0007] Preferably, the cutting control assembly includes: two vertical plates and a shaped roller, the shaped roller being rotatably mounted between the two vertical plates, the two vertical plates being fixedly mounted on the top of the processing table, a limiting shell being fixedly mounted between the two vertical plates, a movable frame being slidably mounted inside the limiting shell, two upper pressure blocks and a lower cutting blade being fixedly mounted at the bottom of the movable frame, an outer pressure block being slidably mounted outside the upper pressure blocks, and multiple support springs and dampers being fixedly mounted inside the outer pressure blocks, the support springs being sleeved on the outside of the dampers.

[0008] Preferably, the heating composite assembly includes: two upright plates one and two upright plates two, both of which are fixedly installed on the top of the processing table. A common rotating roller is rotatably installed between the two upright plates one, and a common fusion pressure roller is rotatably installed between the two upright plates two. A motor one is fixedly installed on one side of one of the upright plates two, and the output end of the motor one is fixedly connected to the fusion pressure roller. A gull-shaped heating plate is fixedly installed on the top of the processing table, and the heating plate is located below the fusion pressure roller.

[0009] Preferably, the limiting shell has a sliding groove that matches the upper pressure block, the outer pressure block, and the moving frame, the outer pressure block has a moving groove that matches the upper pressure block, the support spring and the damper are both fixedly installed in the moving groove, and the support spring and the damper are both fixedly connected to the bottom end of the upper pressure block.

[0010] Preferably, the top of the processing table is provided with an installation groove that matches the heating plate, one of the vertical plates is fixedly installed with a motor, the output end of the motor is fixedly connected to the shaped roller, and the other vertical plate is provided with a rotating circular hole that matches the shaped roller.

[0011] Preferably, a limiting slider is fixedly installed at the bottom end of one of the upright plates, a limiting square groove matching the limiting slider is opened on the processing table, a screw is threadedly connected to the limiting slider, the screw is threadedly connected to the processing table, and multiple support legs are fixedly installed at the bottom end of the processing table.

[0012] In this utility model, a reflective microbead electrostatic coating production line is described. The process involves checking whether the power equipment, such as the electric push rod, motor one, motor two, and motor four, are properly connected and operating. The high-voltage electrostatic generator is then debugged to ensure it can generate stable high-voltage static electricity to meet the requirements of electrostatic coating. The heating plate is checked to ensure it can heat normally, and a suitable heating temperature is set according to the process requirements. The substrate roll to be processed is installed on the feeding roller to ensure smooth feeding. The reflective microbead material is prepared and placed in a suitable position for subsequent electrostatic coating operations. Motor two is started, driving the receiving roller to rotate. Simultaneously, the feeding roller begins feeding under the traction of the substrate. The substrate unfolds from the feeding roller, passes the processing table, and moves towards the receiving roller. The electric push rod is started, causing its output end to push the lower pressure plate downwards. The lower pressure plate drives the energized plate and multiple corona treatment machines downwards until the multiple high-voltage electrostatic generators on the energized plate approach the substrate surface. The high-voltage electrostatic generators generate high-voltage static electricity, causing the substrate surface to carry a static charge. At the same time, the corona treatment machines perform corona treatment on the substrate surface, improving the adhesion of the substrate surface.

[0013] In this invention, a reflective microbead electrostatic film deposition production line is described. Reflective microbeads are scattered onto the surface of a substrate carrying an electrostatic charge. Due to electrostatic action, the microbeads are uniformly adsorbed onto the substrate, completing the electrostatic film deposition process. The substrate, after electrostatic film deposition, continues to move forward into the heating and composite component area. A heating plate heats the substrate to a certain temperature, which is beneficial for subsequent lamination operations. When the motor starts, it drives the fusion roller to rotate. The substrate is squeezed between the rotating roller and the fusion roller, allowing the reflective microbeads to better fuse with the substrate, forming a composite film. The composite film continues to move forward. The machine moves into the cutting control component area, and the motor starts, driving the shaped roller to rotate. The special shape of the shaped roller periodically pushes the moving frame to slide up and down inside the limiting shell. When the moving frame moves downward, the lower cutter cuts the composite film. At the same time, the upper pressure block and the outer pressure block contact the composite film first and press it to fix it. The support spring and damper inside the outer pressure block can play a buffering role to avoid excessive compression damage to the composite film. After the cutting is completed, the moving frame moves upward under the action of the shaped roller to prepare for the next cutting. The cut composite film is then wound up by the take-up roller to complete the entire production process.

[0014] This utility model has a reasonable structural design and an automated unwinding, beading, lamination, and rewinding process, which reduces manual intervention and increases production capacity. It can reasonably adjust process parameters such as the voltage of the high-voltage electrostatic generator, the temperature of the heating plate, and the pressure of the fusion roller according to different substrates and reflective microbead materials to ensure product quality.
