Description

Technical Field

[0001] This utility model relates to the field of adhesive film edge sealing technology, specifically an edge sealing machine with an added adhesive film cutting mechanism. Background Technology

[0002] Before or after changing the film roll, or when the film has high adhesion, the placement may be off, resulting in the film not being laid in the center, or some of the film having production defects. In this case, some of the film will exceed the working range of the edge banding machine. If the edge banding machine is used for edge banding at this time, the edge banding effect will be poor or the edge banding will not be possible because the film exceeds the edge banding machine. The film that exceeds the edge banding machine will overflow severely after lamination, sticking to the laminated frame. If it overflows to the front and back of the component, it will also affect the overflow effect after the frame is assembled.

[0003] Traditional edge banding machines cannot remove adhesive film that extends beyond the glass edge before edge banding. They cannot achieve stable edge banding when the adhesive film is not centered, resulting in abnormal adhesive overflow after frame assembly. This requires manual touch-up, leading to poor quality of adhesive film cutting and increased production costs.

[0004] Therefore, in order to address the above problems, a method is proposed to add a film cutting mechanism to the edge banding machine. Utility Model Content

[0005] In order to overcome the shortcomings of the prior art, at least one technical problem raised in the background art is solved.

[0006] The technical solution adopted by this utility model to solve its technical problem is as follows: The edge banding machine of this utility model adds a film cutting mechanism, including a machine body, a protective shell fixed to one side of the machine body, a liftable cutter installed inside the protective shell, a receiving plate fixed to the bottom surface of the inner wall of the protective shell at a position corresponding to the cutter, and a knife groove adapted to the cutter is opened inside the receiving plate.

[0007] Preferably, a material discharge groove is provided in the middle of the bottom surface of the inner wall of the protective shell, and a chamfer is provided on the top surface of the receiving plate near the material discharge groove.

[0008] Preferably, a transmission plate is fixedly connected to the side of the cutter near the material discharge chute, and a hydraulic rod is fixedly connected to the top of the transmission plate. The top of the hydraulic rod is fixedly connected to the protective housing.

[0009] Preferably, the transmission plate consists of two horizontal sections and one vertical section, with a smooth transition between the horizontal and vertical sections.

[0010] Preferably, multiple guide sliders are fixed to both sides of the transmission plate, and multiple grooves adapted to the guide sliders are opened on both sides of the inner wall of the protective shell, with each guide slider corresponding to one of the multiple grooves.

[0011] Preferably, a pressure sensor is fixedly connected to the inner wall of the protective housing at a position corresponding to the cutter and the receiving plate, and the pressure sensor is connected to an external control system signal via an electrical signal.

[0012] Preferably, the machine body has a guide groove on the side near the cutter, and the protective shell has a feed groove on the side away from the machine body.

[0013] Preferably, a breathable grille is installed on the side of the machine body away from the feed chute.

[0014] Preferably, a pair of support plates are fixedly connected to the side of the machine body away from the protective shell, and each pair of support plates is connected to a rotating screw by a thread, and a rotating handle is fixedly connected to the opposite end of each pair of rotating screws.

[0015] Preferably, each of the pair of rotating screws is fixedly connected to a pressing block on the side of each pair of pressing blocks that are close to each other, and each of the pair of pressing blocks is fixedly connected to a rubber sheet on the side of each pair of pressing blocks that are close to each other.

[0016] The advantages of this utility model are: 1. The edge banding machine of this utility model adds a film cutting mechanism. When the excess film moves between the cutter and the receiving plate, the cutter moves downward until it is inserted into the knife groove inside the receiving plate. During this process, the excess film is cut off. Then the cutter returns to its original position and the above steps are repeated until the excess film is completely cut off. This ensures that the size of the film entering the edge banding machine is qualified, guarantees the edge banding quality, and improves production efficiency.

[0017] 2. The edge banding machine of this utility model adds a film cutting mechanism. The waste material can be guided by the material-cutting angle, thereby guiding the waste material into the material discharge trough and finally falling down along the material discharge trough. In actual production, a waste-receiving bucket can be set below the material discharge trough to facilitate the centralized recycling of waste material. This achieves the effect of convenient centralized recycling of waste material and avoids the accumulation of waste material affecting the cutting quality. Attached Figure Description

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0021] like Figures 1 to 5 As shown, an edge banding machine with an added film cutting mechanism includes a machine body 1. A protective shell 2 is fixedly connected to one side of the machine body 1. A liftable cutter 3 is installed inside the protective shell 2. A receiving plate 4 is fixedly connected to the bottom surface of the inner wall of the protective shell 2 at a position corresponding to the cutter 3. A knife groove 5 adapted to the cutter 3 is opened inside the receiving plate 4. During operation, photovoltaic cell encapsulation film is a thermosetting adhesive film used to place between laminated glass. Due to the superior adhesion, durability, and optical properties of EVA film, it is widely used in current components and various optical products. However, in actual use, due to the misalignment of the film, the edge sealing machine often fails to seal the edges properly. By employing this cutting mechanism, it is first installed at the feed end of the edge banding machine. Before entering the edge banding machine, the adhesive film must pass through this film cutting mechanism. When the adhesive film is centered, the cutting mechanism will not operate, and the edge banding machine can proceed normally. When the adhesive film is misaligned or has production defects, causing some film to exceed the edge banding machine's range, the cutting mechanism will operate. When the excess film moves between the cutter 3 and the receiving plate 4, the cutter 3 will move downwards until it inserts into the knife groove 5 inside the receiving plate 4. This completes the cutting of the excess film. The cutter 3 then resets, and the above steps are repeated until the excess film is completely cut off. This ensures that the adhesive film entering the edge banding machine is of acceptable size, guaranteeing edge banding quality and improving production efficiency.

[0022] In one embodiment, a material discharge groove 6 is provided in the middle of the bottom surface of the inner wall of the protective housing 2, and a chamfer 7 is provided on the top surface of the receiving plate 4 near the material discharge groove 6. During operation, if the waste material after cutting the film that exceeds the working area of ​​the edge banding machine is not cleaned up in time, it will affect the subsequent operation effect of the cutting mechanism. To address this, a deflecting angle 7 and a feeding trough 6 are designed. After the film is cut, the waste material from multiple locations will fall due to gravity. At this time, the deflecting angle 7 can guide the waste material into the feeding trough 6 and eventually drop it down along the feeding trough 6. In actual production, a waste collection bin can be set below the feeding trough 6 to facilitate the centralized collection of waste material. This achieves the effect of convenient centralized collection of waste material and avoids the accumulation of waste material affecting the cutting quality.

[0023] In one embodiment, a transmission plate 9 is fixedly connected to the side of the cutter 3 near the material feeding trough 6, and a hydraulic rod 8 is fixedly connected to the top of the transmission plate 9. The top of the hydraulic rod 8 is fixedly connected to the protective housing 2. During operation, when the cutter 3 needs to be raised or lowered, the hydraulic rod 8 is activated to extend and retract. During the extension and retraction of the hydraulic rod 8, the transmission plate 9 is simultaneously extended and retracted. As the transmission plate 9 extends and retracts, the cutter 3 is raised and lowered, thus achieving the effect of automatically driving the cutter 3 to raise and lower. It is understood that using the hydraulic rod 8 to drive the transmission plate 9 to raise and lower in this embodiment is not the only way. The transmission plate 9 can also be raised and lowered by a motor-driven lead screw and nut pair or a cylinder. In actual use, the specific lifting scheme can be designed according to the actual environment.

[0024] In one embodiment, the transmission plate 9 is composed of two horizontal portions and one vertical portion, with a smooth transition between the horizontal and vertical portions; When working, refer to the appendix Figure 4As shown, the transmission plate 9 forms an almost "S" shape with two horizontal parts and one vertical part. During the cutting operation, the hydraulic rod 8 drives the transmission plate 9 to move downwards, and the transmission plate 9 drives the cutter 3 to move downwards to cut the excess film. At this time, the vertical part of the transmission plate 9 also moves downwards. It can be understood that as the cutting operation proceeds, the cut-off waste material will fall into the discharge trough 6. As the transmission plate 9 moves, its vertical part will shield and guide the waste material. Specifically, during the movement, the transmission plate 9 can better guide the waste material into the discharge trough 6. This design facilitates the centralized collection of waste materials and prevents waste materials from falling into the space between the transmission plate 9 and the protective housing 2, thus avoiding waste accumulation and affecting the descent stroke of the transmission plate 9. Furthermore, the shape design of the transmission plate 9 allows for the installation of the hydraulic rod 8 within the protective housing 2, reducing the mechanism's size and improving its applicability. In practical use, the size of the discharge trough 6 can be adjusted appropriately according to the actual operating conditions. It should be noted that when the discharge trough 6 is enlarged, the diameter of the waste-receiving bucket placed below it must also be increased accordingly, requiring a larger footprint.

[0025] Multiple guide sliders 10 are fixed to both sides of the transmission plate 9. Multiple sliding grooves adapted to the guide sliders 10 are opened on both sides of the inner wall of the protective shell 2. The multiple guide sliders 10 correspond one-to-one with the multiple sliding grooves. During operation, as the transmission plate 9 moves up and down, the guide slider 10 also slides in the groove on the inner wall of the protective housing 2. The guide slider 10 and the protective housing 2 can limit and guide the movement of the transmission plate 9, thereby improving the cutting accuracy and the stability of the equipment operation.

[0026] A pressure sensor 11 is fixedly connected to the inner wall of the protective housing 2 at a position corresponding to the cutter 3 and the receiving plate 4. The pressure sensor 11 is connected to the external control system signal via an electrical signal. In actual use, if manual judgment were to be made regarding whether the adhesive film exceeds the working range of the edge banding machine, it would require constant monitoring, which would be a waste of manpower. Therefore, a pressure sensor 11 was designed. When the adhesive film exceeds the working range, the excess portion will contact the pressure sensor 11. Upon receiving the pressure signal, the pressure sensor 11 immediately sends a signal to the external control system. At this point, the external control system will issue a quality control shutdown order, stopping the material feeding. At this time, the excess portion of the adhesive film is precisely between the cutter 3 and the receiving plate 4. The control system continues to control the hydraulic rod 8 to drive the cutter 3 to complete the cutting work. After one cutting work is completed, the external control system controls the edge banding machine to continue feeding, thus achieving the effect of automatically identifying the excess film and automatically cutting it, improving the automation rate. It can be understood that the pressure sensor 11 is connected to the external control system through a signal transmission module, which is installed inside the machine body 1. It should be noted that the signal transmission module is existing technology, and this application will not elaborate on it. At the same time, the specific triggering principle of the pressure sensor 11 is also existing technology, and will not be elaborated on it.

[0027] In one embodiment, a guide groove 12 is provided on the side of the machine body 1 near the cutter 3, and a feed groove is provided on the side of the protective shell 2 away from the machine body 1. Before using this device, it needs to be calibrated to ensure that the edge of the working range of the edge banding machine and the surface of the guide trough 12 are on the same plane. In this way, when the film exceeds the working range of the edge banding machine, the excess part will hit the pressure sensor 11. At the same time, the design of the guide trough 12 can also guide the film and improve the feeding quality of the edge banding machine.

[0028] A ventilation grille 13 is installed on the side of the machine body 1 away from the feed chute 12; During operation, the signal transmission module inside the machine body 1 needs to be in operation, which inevitably generates heat. The design of the ventilation grille 13 facilitates heat dissipation, prevents abnormalities due to overheating, and improves the stability of the equipment.

[0029] In one embodiment, a pair of support plates 14 are fixedly connected to the side of the body 1 away from the protective shell 2. Each of the pair of support plates 14 is connected to a rotating screw 15 by a thread. Each of the two rotating screws 15 is fixedly connected to a rotating handle 16 at the ends of the two rotating screws that are far apart from each other. During operation, when installing in this embodiment, it is necessary to ensure that the edge banding machine used has a plate, block, or other component on its feed side that can be clamped by a pair of rotating screws 15. During installation, the rotating screws 15 can be rotated by turning the rotating handle 16. During the rotation, the rotating screws 15 will move downward synchronously until they contact the plate, block, or other component on the feed side of the edge banding machine and lock in place, thus completing the installation of this embodiment. It should be noted that by designing a pair of rotating screws 15, the extension or retraction length of the upper or lower rotating screws 15 can be freely adjusted during installation. This allows adjustment of the position of the guide groove 12 relative to the edge banding machine, thereby ensuring that the central axis of the feed side of the edge banding machine and the central axis of the guide groove 12 are on the same straight line, avoiding fluctuations during the film feeding process.

[0030] Each pair of rotating screws 15 is fixedly connected to a pressing block 17 on one side close to each other, and each pair of pressing blocks 17 is fixedly connected to a rubber sheet on one side close to each other. During operation, the design of the extrusion block 17 and the rubber on its surface serves two purposes: firstly, the rubber increases friction, and secondly, it reduces wear during installation, thus extending the equipment's lifespan. Specifically, in actual use, grooves can be cut into the rubber surface or rubber with granules can be installed to further increase friction and prevent the equipment from shaking during use.

[0031] Working principle: In actual use, this mechanism is first installed at the feeding end of the edge banding machine. Before the adhesive film enters the edge banding machine, it must first pass through the adhesive film cutting mechanism of this application. When the adhesive film is placed in the center, the cutting mechanism will not run, and the edge banding machine can perform edge banding normally. When the adhesive film is placed in a deviated position, or some adhesive film has production defects, causing some adhesive film to exceed the range of the edge banding machine, the cutting mechanism will run. When the excess adhesive film moves between the cutter 3 and the receiving plate 4, the cutter 3 will move downward until it is inserted into the knife groove 5 inside the receiving plate 4. In this process, the cutting operation of the excess adhesive film is completed. Then the cutter 3 resets and the above steps are repeated until the excess adhesive film is completely cut off, thereby ensuring that the size of the adhesive film entering the edge banding machine is qualified, ensuring the edge banding quality and improving production efficiency. After the film is cut beyond the working area of ​​the edge banding machine, if the waste material is not cleaned up in time, it will affect the subsequent operation of the cutting mechanism. To address this, a deflecting angle 7 and a discharge trough 6 are designed. After the film is cut, the waste material from multiple locations will fall due to gravity. At this time, the deflecting angle 7 can guide the waste material into the discharge trough 6 and eventually drop it down along the discharge trough 6. In actual production, a waste collection bin can be set below the discharge trough 6 to facilitate the centralized collection of waste material. This achieves the effect of convenient centralized collection of waste material and avoids the accumulation of waste material affecting the cutting quality. When the cutter 3 needs to be raised or lowered, the hydraulic rod 8 is activated to extend and retract. During the extension and retraction of the hydraulic rod 8, the transmission plate 9 will extend and retract simultaneously. As the transmission plate 9 extends and retracts, the cutter 3 will be raised and lowered. This achieves the effect of automatically driving the cutter 3 to raise and lower. It is understood that using the hydraulic rod 8 to drive the transmission plate 9 to raise and lower in this embodiment is not the only way. The transmission plate 9 can also be raised and lowered by a motor-driven lead screw and nut pair or a cylinder. In actual use, the specific lifting scheme can be designed according to the actual environment. Reference Appendix Figure 4 As shown, the transmission plate 9 forms an almost "S" shape with two horizontal parts and one vertical part. During the cutting operation, the hydraulic rod 8 drives the transmission plate 9 to move downwards, and the transmission plate 9 drives the cutter 3 to move downwards to cut the excess film. At this time, the vertical part of the transmission plate 9 also moves downwards. It can be understood that as the cutting operation proceeds, the cut-off waste material will fall into the discharge trough 6. As the transmission plate 9 moves, its vertical part will shield and guide the waste material. Specifically, during the movement, the transmission plate 9 can better guide the waste material into the discharge trough 6. This design facilitates the centralized collection of waste materials and prevents waste materials from falling into the space between the transmission plate 9 and the protective shell 2, thus avoiding waste accumulation and affecting the descent stroke of the transmission plate 9. Furthermore, the shape design of the transmission plate 9 allows for the installation of the hydraulic rod 8 within the protective shell 2, reducing the mechanism's size and improving its applicability. In practical use, the size of the discharge trough 6 can be adjusted appropriately according to the actual operating conditions. It should be noted that when the discharge trough 6 is enlarged, the diameter of the waste-receiving bucket placed below it must also be increased accordingly, requiring a larger footprint. During the lifting and lowering process of the transmission plate 9, the guide slider 10 will also slide in the groove on the inner wall of the protective housing 2. The guide slider 10 and the protective housing 2 can limit and guide the movement of the transmission plate 9, thereby improving the cutting accuracy and the stability of the equipment operation. In practical use, if manual judgment is required to determine whether the adhesive film exceeds the working range of the edge banding machine, the operator needs to constantly monitor the machine, which is a waste of manpower. Therefore, a pressure sensor 11 is designed. When the adhesive film exceeds the working range of the edge banding machine, the excess part of the adhesive film will come into contact with the pressure sensor 11. After receiving the pressure signal, the pressure sensor 11 will immediately send a signal to the external control system. At this time, the external control system will issue a quality control shutdown for the edge banding machine, i.e., stop feeding. At this time, the excess part of the adhesive film is exactly between the cutter 3 and the receiving plate 4. The external control system continues to control the hydraulic rod 8 to drive the cutter 3 to complete the cutting work. After one cutting work is completed, the external control system controls the edge banding machine to continue feeding. This achieves the effect of automatically identifying the excess part of the adhesive film and automatically cutting it, thus improving the automation rate. It can be understood that the pressure sensor 11 is connected to the external control system through a signal transmission module, which is installed inside the machine body 1. It should be noted that the signal transmission module is existing technology, and this application will not elaborate on it further. Before using this device, it needs to be calibrated, that is, it needs to be ensured that the edge of the working range of the edge banding machine and the surface of the guide trough 12 are on the same plane. In this way, when the film exceeds the working range of the edge banding machine, the excess part will hit the pressure sensor 11. At the same time, the design of the guide trough 12 can also guide the film and improve the feeding quality of the edge banding machine. During the operation of the mechanism, the signal transmission module inside the machine body 1 needs to be in operation at all times, which inevitably generates heat. The design of the ventilation grille 13 can facilitate heat dissipation, prevent it from malfunctioning due to overheating, and improve the stability of the equipment. During installation in this embodiment, it is necessary to ensure that the edge banding machine used has a plate, block, or other component on its feed side that can be clamped by a pair of rotating screws 15. During installation, the rotating screws 15 can be rotated by turning the rotating handle 16. During the rotation, the rotating screws 15 will move downward synchronously until they contact the plate, block, or other component on the feed side of the edge banding machine and lock in place, thus completing the installation of this embodiment. It should be noted that by designing a pair of rotating screws 15, the extension or retraction length of the upper or lower rotating screws 15 can be freely adjusted during installation. This allows adjustment of the position of the guide trough 12 relative to the edge banding machine, thereby ensuring that the central axis of the feed side of the edge banding machine and the central axis of the guide trough 12 are on the same straight line, avoiding fluctuations during the film feeding process.
