Description

Technical Field

[0001] This invention relates to the field of diffusion membrane production technology, specifically to a diffusion membrane production apparatus and process. Background Technology

[0002] Diffusing films are used to diffuse light from point and line light sources, adjusting the emission angle of light to make the light passing through the diffuser uniform and soft, and increasing the viewing angle. When light passes through the diffusion layer with PET as the substrate, it will pass through a medium with a different refractive index, causing many refraction, reflection and scattering phenomena to occur. It can correct the light to become a uniform surface light source to achieve the effect of optical diffusion.

[0003] After being cut by a die-cutting machine, the diffusion film is in a state of not being completely detached. Currently, the separation method is to separate it by using rubber rollers, which can easily result in the film not being able to detach or leaving residue on the diffusion film. After cutting, it is generally transported by a conveyor to a manual place for weighing and packaging, which is time-consuming, labor-intensive and inefficient. In order to solve the above problems, the inventor proposes a diffusion film production device and process. Summary of the Invention

[0004] To address the problems of diffusion film separation via rubber rollers, such as failure to detach or residue, and the time-consuming, labor-intensive, and inefficient manual weighing and repackaging process, the present invention aims to provide a diffusion film production apparatus and process.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: a diffusion film production device, including a worktable, a conveying mechanism, and a die-cutting machine. The worktable and the conveying mechanism are aligned. The die-cutting machine is fixedly installed on the worktable and can cut the diffusion film. A winding groove is provided at the end of the worktable away from the conveying mechanism. A winding shaft is rotatably installed inside the winding groove. The winding shaft can easily change the direction of movement of the diffusion film. A discharge groove is provided at the end of the worktable away from the winding groove. A winding shaft is rotatably installed inside the discharge groove. A separation component is provided at the end of the worktable near the conveying mechanism. The separation component can easily separate the die-cut diffusion film from waste. A metering component is provided at the end of the conveying mechanism away from the worktable. The metering component can quantitatively dispense the diffusion film, avoiding the need for manual weighing. Symmetrically distributed auxiliary components are provided on the worktable. The auxiliary components can keep the structural movement in the separation component stable. The opposite side of the auxiliary components is fixedly connected to the separation component. A winding component is provided on the worktable. The winding component can easily wind the diffusion film and the protective film, thereby facilitating loading and unloading.

[0006] Preferably, the separation assembly includes a pressure plate, a connecting plate fixedly mounted on the outer side of the pressure plate, and a fixed connection at the far end of the connecting plate to the moving end of the die-cutting machine. A pair of parallel pressure rods are fixedly mounted on the side of the pressure plate near the worktable. A first groove is fitted on the side of the worktable near the pressure plate. A top plate is slidably fitted inside the first groove, with one side of the top plate aligned with one side of the pressure plate. A pair of parallel guide rods movably pass through the inside of the first groove. One end of each guide rod is fixedly connected to the top plate, and a first spring is movably fitted on the outer side of each guide rod. Both ends of the first spring are fixedly connected to the inner wall of the first groove and one side of the top plate, respectively. The moving end of the die-cutting machine drives the connecting plate to move, which in turn drives the pressure plate to move. The pressure plate then drives the pressure rods to move, causing the pressure rods to press against the diffusion film. The pressure rods continue to move downwards, causing the top plate to move within the first groove. The guide rods maintain the stability of the top plate's movement. The top plate compresses the first spring, causing it to generate elastic force, thus separating the diffusion film from the waste material. The first spring can then use its elastic force to reset the top plate.

[0007] Preferably, the quantitative component includes a support plate, which is symmetrically distributed and fixedly installed on the conveying mechanism. A rotating shaft is rotatably installed on the opposite side of the support plate. A motor is fixedly installed on the side of the support plate away from the rotating shaft. The motor is electrically connected to a PLC controller. The end of the motor output shaft movably passes through the support plate and is fixedly connected to the rotating shaft. A collection box is fixedly installed on the outside of the rotating shaft. A tray is slidably mounted inside the collection box. An elastic arc plate is movably arranged inside the collection box. The elastic arc plate fits against the tray. The diffusion film is conveyed into the collection box by the conveying mechanism and falls onto the tray. As the diffusion film accumulates to a fixed weight, it drives the tray to move downward. The tray squeezes the elastic arc plate, causing the two ends of the elastic arc plate to move in opposite directions. In this way, the weight can deform the elastic arc plate. Then, the end of the motor output shaft drives the rotating shaft to rotate a quarter turn. The rotating shaft drives the collection box to rotate, so that the diffusion film in the collection box falls to the back of another collection box for easy retrieval.

[0008] Preferably, the auxiliary component includes a fixing plate, a first sliding groove is provided on the opposite side of the fixing plate, a slider is slidably mounted inside the first sliding groove, one end of the slider is fixedly connected to the pressure plate, a first fixing rod is fixedly mounted inside the first sliding groove, one end of the first fixing rod movably passes through the slider, the pressure plate drives the slider to move in the first sliding groove, and the first fixing rod keeps the slider moving stably, thus making the pressure plate move stably, thereby achieving the purpose of improving stability.

[0009] Preferably, the collection box has symmetrically distributed second sliding grooves inside, and a push plate is movably engaged inside the second sliding groove. One side of the push plate is fixedly connected to an elastic arc plate. A second fixing rod is fixedly engaged inside the second sliding groove, with one end of the second fixing rod movably penetrating the push plate. A second spring is movably sleeved on the outside of the second fixing rod, with both ends of the second spring fixedly connected to the inner wall of the second sliding groove and one side of the push plate, respectively. The elastic arc plate drives the push plate to move, and the second fixing rod keeps the push plate moving stably. The push plate drives the push rod to move, compressing the second spring and causing it to generate elastic force. A second groove is formed at the end of the collection box away from the rotating shaft, and a first contact opening is slidably engaged inside the second groove. The conveying mechanism has a connecting rod fixedly installed at the end away from the worktable. A second contact switch is installed on the side of the connecting rod away from the worktable. The second contact switch is aligned with the first contact switch. The first and second contact switches are electrically connected to the PLC controller. A push rod drives the first contact switch to move in the second groove, so that the first and second contact switches make contact and form a circuit. This facilitates the transmission of electrical signals to the PLC controller, thereby facilitating motor control. A push rod is fixedly installed on the side of the push plate away from the rotating shaft. One end of the push rod movably passes through the collection box and is fixedly connected to the first touch switch. The push plate drives the push rod to move, and the push rod drives the first contact switch to move, so that the push plate and the first contact switch can be linked.

[0010] Preferably, the winding assembly includes uprights, three of which are arranged side by side and fixedly installed on the worktable. A first feeding roller, a second feeding roller, and a take-up roller are sequentially arranged on the three uprights. The diffusion film and the protective film are respectively installed on the first feeding roller and the second feeding roller. One end of the diffusion film and the protective film are wrapped around the winding shaft in the winding groove and aligned. Then, the waste material is wrapped around the winding shaft in the discharge groove and wound onto the take-up roller.

[0011] Preferably, a guide plate is fixedly provided at one end of the workbench near the conveying mechanism, and the other end of the guide plate away from the workbench is located above the conveying mechanism. The guide plate is aligned with the discharge chute. The fact that one end of the guide plate is located above the conveying mechanism allows the diffusion film to fall directly onto the conveying mechanism, thereby facilitating the conveying of the diffusion film.

[0013] S1, Ingredients: PETG granules, lubricant, compatibilizer, antioxidant, light stabilizer, thixotropic agent and catalyst are added to a mixing device and mixed to obtain a mixture;

[0022] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0023] 1. By continuously accumulating diffusion film to a fixed weight, the pallet moves downward. The pallet squeezes the elastic arc plate, causing the two ends of the elastic arc plate to move in opposite directions. The elastic arc plate drives the push plate to move, the push plate drives the push rod to move, and the push rod drives the first contact switch to move, so that the first contact switch and the second contact switch make contact to form a passage. Then, the end of the motor output shaft drives the rotating shaft to rotate a quarter turn, and the rotating shaft drives the collection box to rotate, so that the diffusion film in the collection box falls to the back of another collection box for easy retrieval. This can avoid the need for manual weighing and quantification, thereby improving packaging efficiency.

[0024] 2. The moving end of the die-cutting machine drives the connecting plate to move, the connecting plate drives the pressure plate to move, and the pressure plate drives the pressure rod to move, so that the pressure rod presses the diffusion film tightly. Then, the pressure rod continues to move downward, and the pressure rod drives the top plate to move in the first groove. In this way, the diffusion film and waste can be separated, thereby achieving the purpose of convenient separation. Attached Figure Description

[0040] By adopting the above technical solution, the diffusion film is conveyed into the collection box 603 by the conveying mechanism 2 and falls onto the tray 604. As the diffusion film accumulates to a fixed weight, it drives the tray 604 to move downward. The tray 604 squeezes the elastic arc plate 605, causing the two ends of the elastic arc plate 605 to move in opposite directions. In this way, the weight can deform the elastic arc plate 605. Then, the end of the output shaft of the motor 615 drives the rotating shaft 602 to rotate a quarter turn. The rotating shaft 602 drives the collection box 603 to rotate, so that the diffusion film in the collection box 603 falls to the back side of another collection box 603 for easy retrieval.

[0048] By adopting the above technical solution, the push rod 614 drives the first contact switch 611 to move in the second groove 610, so that the first contact switch 611 and the second contact switch 613 make contact to form a circuit. This makes it convenient to transmit electrical signals to the PLC controller, thereby facilitating the control of the motor 615.

[0053] Example 2:

[0054] A process for a diffusion film production apparatus, characterized in that it includes the diffusion film production apparatus as described in claims 1-9, comprising the following steps:

[0055] S1, Ingredients: PETG granules, lubricant, compatibilizer, antioxidant, light stabilizer, thixotropic agent and catalyst are added to a mixing device and mixed to obtain a mixture;

[0056] S2, Extrusion: The mixture is added to a single screw extruder for melt extrusion. Extrusion temperature: 240-170℃;

[0057] S3, casting: The extruded workpiece is placed on the PETG film production sheet feeding device for casting.

[0058] S4, stretching, placing the sheet-like workpiece onto the stretching equipment, and stretching the workpiece laterally and longitudinally through the stretching equipment;

[0059] S5, heat treatment, heat treatment of the stretched workpiece using heat treatment equipment;

[0060] S6, Cooling, the workpiece is cooled by a cooler;

[0061] S7. After winding and laminating, the workpiece is wound and packaged according to production requirements.

[0062] S8, Surface treatment, applying a protective coating to the surface of the workpiece;

[0063] S9, Die-cutting, which cuts rolled workpieces into finished products according to actual use.

[0064] Working principle: First, the diffusion film and the protective film are installed on the first feeding roller 82 and the second feeding roller 83 respectively. One end of the diffusion film and the protective film are wrapped around the winding shaft in the winding groove and aligned. Then, they are passed through the die-cutting machine 4 for die cutting. Next, the waste material is wrapped around the winding shaft in the discharge groove and wound onto the take-up roller 84.

[0065] When the die-cut diffusion film moves onto the top plate 55, the moving end of the die-cutting machine 4 moves downward, driving the connecting plate 53 to move. The connecting plate 53 drives the pressure plate 51 to move, and the pressure plate 51 drives the pressure rod 52 to move, causing the pressure rod 52 to press the diffusion film. Then, the pressure rod 52 continues to move downward, driving the top plate 55 to move within the first groove 54. The guide rod 57 keeps the top plate 55 moving stably, and the top plate 55 compresses the first spring 56, causing the first spring 56 to generate elastic force, thus separating the diffusion film from the waste material. At the same time, the pressure plate 51 drives the slider 73 to move within the first groove 72, and the first fixing rod 74 keeps the slider 73 moving stably, thus stabilizing the pressure plate 51. Subsequently, the top plate 55 is reset by the elastic force of the first spring 56, and then the diffusion film moves backward, causing the separated diffusion film to move into the discharge trough. It then moves to the conveying mechanism 2 via the guide slope 3. The conveying mechanism 2 transports the diffusion film into the collection box 603 and onto the tray 604. As the diffusion film accumulates to a fixed weight, it drives the pallet 604 downwards. The pallet 604 presses against the elastic arc plate 605, causing the two ends of the elastic arc plate 605 to move in opposite directions. The elastic arc plate 605 drives the push plate 607 to move, and the second fixing rod 608 keeps the push plate 607 moving stably. At the same time, the push plate 607 compresses the second spring 609, causing the second spring 609 to generate elastic force. The push plate 607 drives the push rod 614 to move, and the push rod 614 drives the first contact switch 611 to move in the second groove 610, so that the first contact switch 611 and the second contact switch 613 make contact to form a passage. Then, the PLC controller starts the motor 615, so that the motor 615 starts to work. The end of the output shaft of the motor 615 drives the rotating shaft 602 to rotate a quarter turn. The rotating shaft 602 drives the collection box 603 to rotate, so that the diffusion film in the collection box 603 falls to the back of another collection box 603 for easy retrieval. This avoids the need for manual weighing and quantitative measurement, thereby improving packaging efficiency.

Therefore, if these modifications and variations fall within the scope of the claims of this invention and their equivalents, this invention also intends to include these modifications and variations.
