Description

Technical Field

[0001] This utility model relates to the field of tempered glass production technology, specifically to a tempered glass film application device. Background Technology

[0002] Tempered glass film application equipment is widely used in tempered glass production. However, existing tempered glass film application equipment has many shortcomings in actual use.

[0003] Firstly, in traditional tempered glass film application equipment, the feeding mechanism and the film-laying mechanism are often independent of each other, lacking an effective linkage mechanism. This makes it difficult to synchronize the feeding and film-laying actions, resulting in the film not being laid evenly and smoothly on the glass, which not only affects the film quality but also reduces work efficiency.

[0004] Furthermore, traditional equipment often struggles to adjust the pressure applied during the lamination process based on the varying thickness and material of the film. This results in insufficient expulsion of water and air between the film and the glass, leading to defects such as bubbles and wrinkles, which severely impacts the adhesion and overall product quality. Utility Model Content

[0005] The purpose of this invention is to provide a tempered glass film application device to solve the problems mentioned in the background art regarding the synchronization of feeding and film laying in existing tempered glass film application devices and the problems existing in film pressing.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a tempered glass film application device, comprising a worktable, a feeding plate, a water spraying mechanism, a film laying mechanism, and a film pressing frame arranged sequentially along the length of the worktable, and further comprising a first driving mechanism and a second driving mechanism disposed on the worktable; the feeding plate is slidably disposed along the length of the worktable, the film laying mechanism is rotatably connected to the worktable, the film pressing frame is vertically slidably disposed on the worktable, the first driving mechanism is driven to move the feeding plate and the film laying mechanism, the first driving mechanism drives the feeding plate to move and drives the film laying mechanism to rotate, and the second driving mechanism is driven to move the film pressing frame vertically.

[0007] Furthermore, a baffle is provided on one side of the feeding plate.

[0008] Furthermore, the water spraying mechanism includes a gantry frame located on the upper part of the workbench and a nozzle located at the bottom of the gantry frame; a water pipe is provided on the upper part of the gantry frame.

[0009] Furthermore, the film-laying mechanism includes support plates located on both sides of the center of the workbench and a film-laying roller rotatably connected between the two support plates.

[0010] Furthermore, the pressing frame is rectangular and its two vertical walls are vertically slidably connected to the two sides of the worktable, and the bottom of the pressing frame is located at the bottom of the worktable.

[0011] Furthermore, the first driving mechanism includes a motor mounted on the worktable, a lead screw rotatably connected to the bottom of the worktable and connected to the output shaft of the motor, a movable block threadedly connected to the lead screw, and L-shaped plates on both sides of the movable block; a sliding groove is provided on the worktable, the movable block is located in the sliding groove and slides with the sliding groove, the upper part of the movable block passes through the sliding groove and is connected to the feeding plate, and racks are provided on both L-shaped plates, and both ends of the coating roller are located outside the support plate and connected to gears, and the racks mesh with the gears.

[0012] Furthermore, the second driving mechanism is specifically an electric actuator, which is located at the bottom of the worktable and its output shaft is connected to the bottom of the pressure film frame.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] 1. This utility model, by setting up a first driving mechanism, utilizes a motor to drive a lead screw to rotate, causing a moving block to move along the lead screw, which in turn drives the feeding plate to move. Simultaneously, the racks on the L-shaped plates on both sides of the moving block mesh with the gears at both ends of the coating roller, achieving synchronous movement of the feeding plate and the coating roller. This solves the problem of asynchronous feeding and film laying in traditional devices, ensuring that the film can be laid evenly and flatly on the glass, improving the automation level and work efficiency of film laying.

[0015] 2. The second drive mechanism uses an electric push rod with a self-locking function, which can precisely adjust the downward pressure of the film pressing frame according to the different thicknesses and materials of the film. When the film pressing frame presses down, it can fully squeeze out the water and air between the film and the glass, so that the film adheres tightly to the glass surface, effectively avoiding defects such as bubbles and wrinkles, and improving the quality and adhesion of the film.

[0016] 3. The water spraying mechanism consists of a gantry frame and nozzles. Multiple nozzles are installed along the gantry frame, enabling the uniform spraying of water onto the glass surface to form an ideal water film. This water film not only reduces air residue between the glass and the film but also lowers frictional resistance during the application process, making it easier for the film to adhere to the glass and further improving the quality and efficiency of the application.

[0024] Please see Figures 1 to 5 This utility model provides a tempered glass film application device, the core components of which include a worktable 1, and a feeding plate 2, a water spraying mechanism, a film laying mechanism, and a film pressing frame 3 arranged sequentially along the length of the worktable 1. In addition, a first drive mechanism and a second drive mechanism are also provided on the worktable for driving the operation of each actuator.

[0025] The feed plate 2 is slidably mounted on the worktable 1 along its length and can move back and forth along this direction. A baffle 4 is fixed on one side of the feed plate 2 to limit the tempered glass placed on the feed plate and ensure that the glass is accurately positioned during the conveying process.

[0026] The water spraying mechanism consists of a gantry frame 5 and nozzles 6. The gantry frame 5 is fixed to the upper part of the workbench 1, and the nozzles 6 are installed at its bottom (multiple nozzles 6 are installed along the gantry frame 5). A water pipe 7 is connected to the upper part of the gantry frame 5. One end of the water pipe 7 is connected to an external water source (such as a water pump or water supply pipe), and the other end is connected to the nozzles 6 to provide water for the nozzles 6.

[0027] The film-laying mechanism includes two support plates 8 and a film-coating roller 9. The two support plates 8 are fixed on both sides of the middle of the worktable 1. The film-coating roller 9 is rotatably connected between the two support plates 8 through bearings, and its two ends extend to the outside of the two support plates 8 and are connected to gears 16.

[0028] The pressure frame 3 has a rectangular structure, and its two vertical walls are vertically slidably connected to the two sides of the worktable 1 (such as guide rails and sliders), allowing it to move up and down vertically. In its initial position, the bottom of the pressure frame 3 is located at the bottom of the worktable 1, and when pressed down, it covers the working area of ​​the worktable 1.

[0029] The first driving mechanism includes a motor 10, a lead screw 11, a moving block 12, and an L-shaped plate 13. The motor 10 is fixed on the worktable 1, and its output shaft is connected to one end of the lead screw 11. The lead screw 11 is rotatably connected to the bottom of the worktable 1 via a bearing. The moving block 12 is threadedly connected to the lead screw 11. A slide groove 14 is provided on the worktable 1, and the moving block 12 is located in the slide groove 14 and slides within the slide groove 14. Its upper part passes through the slide groove 14 and is fixedly connected to the feeding plate 2. The feeding plate 2 is threadedly connected to the lead screw 11 of the first driving mechanism via the moving block 12. When the motor 10 drives the lead screw 11 to rotate, the moving block 12 moves along the lead screw 11, thereby causing the feeding plate 2 to slide along the length of the worktable 1. An L-shaped plate 13 is fixed on each side of the moving block 12. A rack 15 is provided on the L-shaped plate 13, and the rack 15 meshes with the gears 16 at both ends of the coating roller 9. The two L-shaped plates 13 are located outside the vertical walls on both sides of the film pressing frame 3. The film-laying mechanism's film-coating roller 9 meshes with the rack 15 of the first drive mechanism via gear 16. When the moving block 12 moves, the rack 15 on the L-shaped plate 13 drives the gear 16 to rotate, thereby causing the film-coating roller 9 to rotate.

[0030] The second driving mechanism is an electric actuator 17, which has a self-locking function. The electric actuator 17 is fixed to the bottom of the worktable 1, and its output shaft is connected to the bottom of the pressing frame 3, which is used to drive the pressing frame 3 to move vertically. The pressing frame 3 slides vertically through the output shaft of the electric actuator 17, and the extension and retraction of the electric actuator 17 drives the pressing frame 3 to move up and down.

[0031] Working principle of this utility model:

[0032] (a) Feeding stage

[0033] Power transmission: The motor 10 of the first drive mechanism is started, and the output shaft of the motor 10 drives the lead screw 11 to rotate. Since the moving block 12 is threadedly connected to the lead screw 11, and the moving block 12 is restricted by the slide groove 14 to move only along the axial direction of the lead screw 11, the rotation of the lead screw 11 is converted into the linear movement of the moving block 12.

[0034] Feeding action: The moving block 12, connected to the feeding plate 2 at the top, drives the feeding plate 2 to move along the length of the worktable 1 towards the side closer to the film-laying mechanism. The baffle 4 on the feeding plate 2 limits the tempered glass, ensuring that the glass moves synchronously with the feeding plate 2 and is conveyed to the area below the water spraying mechanism.

[0035] (ii) Spraying water to wet the stage

[0036] Water spray mechanism operation: When the tempered glass moves with the feeding plate 2 to below the gantry frame 5, the water source of the water spray mechanism is turned on (such as opening the valve on the water pipe 7 or starting the water pump). The water flows through the water pipe 7 into the nozzle 6, and the nozzle 6 sprays water onto the glass surface to wet the glass surface (the purpose of spraying water is to form a water film on the glass surface, reduce the air residue between the glass and the film, and at the same time reduce the frictional resistance during the film application process, making it easier for the film to adhere to the glass).

[0037] (III) Film Laying Stage

[0038] Rotation of the coating roller: When the moving block 12 moves one end of the feeding plate 2 to below the coating roller 9, the racks 15 on the L-shaped plates 13 on both sides of the moving block 12 move together with the moving block 12 to the gears 16 at both ends of the coating roller 9. Since the racks 15 mesh with the gears 16 at both ends of the coating roller 9, the linear movement of the racks 15 is converted into the rotation of the gears 16, which in turn drives the coating roller 9 to rotate.

[0039] Film application: The film is wound around the laminating roller 9. As the laminating roller 9 rotates, the film is gradually unfolded and laid on the wet glass surface. The movement of the feed plate 2 is synchronized with the rotation of the laminating roller 9 to ensure that the film is laid evenly and flatly on the glass. When the film covers the entire tempered glass, it is cut by the operator.

[0040] (iv) Film pressing stage

[0041] Pressing down the film frame: When one end of the tempered glass is below the film frame 3 after the film is applied, the electric push rod 17 of the second drive mechanism is activated simultaneously. The output shaft of the electric push rod 17 retracts downward, pushing the film frame 3 to move downward along the vertical guide rails on both sides of the worktable 1, so that the upper and lower bottom of the film frame 3 are attached to the glass and the film above.

[0042] Extrusion and bonding: When the film pressing frame 3 presses down, it applies a certain pressure to the film and glass, squeezing out the water and air between the film and the glass, making the film adhere tightly to the glass surface, ensuring that there are no air bubbles or wrinkles between the film and the glass, and improving the quality and adhesion of the film (the operator must closely monitor the positional relationship between the tempered glass and the film being applied, and adjust it in time if there is any misalignment). As the feeding plate 2 moves the tempered glass continuously, after all the films applied to the tempered glass are extruded and bonded, the operator removes the tempered glass from the other side of the workbench 1 for the next film application operation.

[0043] The first drive mechanism of this invention uses a motor 10 as a power source and a transmission structure of lead screw 11-moving block 12 to realize the linear movement of the feeding plate 2. Simultaneously, the rotation of the laminating roller 9 is achieved through the meshing transmission of rack 15-gear 16, allowing the feeding and film-laying actions to be performed synchronously, improving the automation level and work efficiency of the laminating device. The electric push rod 17 of the second drive mechanism independently controls the lifting and lowering of the film pressing frame 3. It can adjust the downward pressure and dwell time of the film pressing frame 3 according to different film thicknesses and materials to ensure optimal laminating effect.
