A flip-type double-sided automatic film applicator

Abstract

This utility model relates to the field of automatic film application technology and discloses a flip-type double-sided automatic film application machine, including a film application table. A fixed limiting block is fixedly installed on the upper surface of the film application table, and a movable block is movably connected to the upper part of the fixed limiting block. A threaded rod is threadedly connected to the inside of the movable block. This utility model allows the movable block to be initially positioned at the leftmost end of the fixed limiting block, facilitating the placement of the film roll and the take-up roll onto the surface of the mounting shaft. Rotating the knob causes the threaded rod to rotate inside the movable block. Because the threaded rod rotates inside the ball bearings, and due to the limiting action of the limiting rod, the position of the baffle in the front-to-back direction is adjusted. This device, by limiting the film roll and the take-up roll, and in conjunction with the rotation of the ball bearings, better prevents the film from moving back and forth with the rotation of the mounting shaft, thus ensuring the flatness of the film output and facilitating the rapid installation of the film roll.

Description

Technical Field

[0001] This utility model relates to the field of automatic film application technology, and more specifically, to a flip-type double-sided automatic film application machine. Background Technology

[0002] The flip-type double-sided film applicator, through automated operation, enables rapid double-sided film application to workpieces, significantly improving production efficiency. Compared to traditional manual film application methods, the flip-type double-sided film applicator eliminates the need for manual cutting and pasting, greatly saving labor and time costs. Simultaneously, the machine's precision and stability ensure the high efficiency and reliability of the film application process.

[0003] However, before applying the film, the film roll and the take-up roller need to be placed on the surface of the rotating roller. However, as the film is taken back, the friction between the film and various components can easily cause the film roll to move back and forth, resulting in uneven film output or even wrinkles during application. Existing devices also have a limiting structure, but the limiting structure is difficult to disassemble and has significant friction. Therefore, it is necessary to improve and optimize a flip-type double-sided automatic film applicator. Utility Model Content

[0004] In order to overcome the shortcomings of the existing technology, this utility model provides a flip-type double-sided automatic film applicator, which has the advantages of ensuring that the film does not move back and forth as the mounting shaft rotates, thus ensuring the flatness of the film output and facilitating the quick installation of the film roll.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a flip-type double-sided automatic film applicator, comprising an applicator table, a fixed limiting block fixedly installed on the upper surface of the applicator table, a movable block movably connected to the upper part of the fixed limiting block, a threaded rod rotatably connected inside the movable block, a knob fixedly connected to the front end of the threaded rod, a baffle rotatably connected to the rear end of the threaded rod, a limiting rod fixedly connected to the rear surface of the movable block, the surface of the limiting rod movably connected to the interior of the baffle, a ball bearing fixedly installed at the rear of the baffle, and a material feeding structure provided on the upper part of the applicator table.

[0006] As a preferred technical solution of this utility model: a fixed frame is fixedly connected to the upper surface of the film application table, a first motor is fixedly installed on the upper part of the fixed frame, a rotating frame is fixedly connected to the output shaft of the first motor, a bidirectional threaded rod is rotatably connected inside the rotating frame, a first gear is fixedly sleeved on the surface of the bidirectional threaded rod, a toothed rod is movably connected to the surface of the rotating frame, the toothed rod and the first gear mesh with each other, a driving structure is provided in the middle of the fixed frame, and a clamping structure is provided on the surface of the bidirectional threaded rod.

[0007] As a preferred technical solution of this utility model: the driving structure includes a rotating shaft rotatably connected to the upper part of the film application table, a turbine fixedly sleeved on the surface of the rotating shaft, a second gear fixedly sleeved on the surface of the rotating shaft, the second gear meshing with a rack, a second motor fixedly installed in the middle of the fixing frame, and a worm gear fixedly connected to the output shaft of the second motor, the worm gear meshing with the turbine.

[0008] As a preferred technical solution of this utility model: the clamping structure includes a clamping assembly threaded to the surface of a bidirectional threaded rod, the interior of the clamping assembly is movably connected to the surface of the rotating frame, a glass sheet is movably connected to the inner side of the clamping assembly, a bracket is provided below the glass sheet, an electric push rod is fixedly connected to the lower surface of the bracket, the lower part of the electric push rod is fixedly connected to the upper surface of the film application table, and the surface of the bracket is movably connected to the interior of the film application table.

[0009] As a preferred technical solution of this utility model: the material feeding structure includes a film applicator fixedly connected to the upper surface of the film applicator, a mounting shaft is rotatably connected inside the film applicator, a third motor is fixedly installed on the upper part of the film applicator, the output shaft of the third motor is fixedly connected to the rear end of the upper mounting shaft, a belt is connected between the upper and lower mounting shafts, and an electric rotating rod is fixedly installed on the front surface of the film applicator.

[0010] As a preferred technical solution of this utility model: a transverse moving device is fixedly installed on the upper surface of the film applicator, and a moving plate is internally threaded to the transverse moving device.

[0011] As a preferred technical solution of this utility model: a cylinder is fixedly installed on the upper part of the moving plate, a film suction assembly is fixedly installed on the output shaft of the cylinder, and a film scraping device is fixedly installed on the upper left surface of the film suction assembly.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] 1. This utility model uses a movable block initially positioned at the leftmost end of a fixed limiting block, facilitating the placement of the film roll and the take-up roll onto the surface of the mounting shaft. Rotating the knob causes the threaded rod to rotate inside the movable block. Because the threaded rod rotates inside the ball bearings, and due to the limiting action of the limiting rod, the position of the baffle in the front-to-back direction is adjusted. This device limits the film roll and take-up roll, and, in conjunction with the rotation of the ball bearings, better prevents the film from shifting forward or backward with the rotation of the mounting shaft, thus ensuring flat film output and facilitating quick installation of the film roll.

[0014] 2. This utility model uses the rotation of the output shaft of the first motor to drive the rotation of the rotating frame, which in turn causes the clamping assembly and the bidirectional threaded rod to rotate, thereby achieving the function of flipping the glass sheet. However, the rotation of the output shaft of the second motor drives the rotation of the worm gear. The meshing of the worm gear and the worm wheel drives the rotation of the second gear. Through the transmission action of the rack, the rotation of the bidirectional threaded rod is realized, which enables the clamping assembly to clamp the glass sheet. This device adopts step-by-step control to achieve the flipping. When placing the glass sheet, the operator only needs to place the glass sheet on the surface of the bracket and align the front end of the glass sheet with the middle of the rotating frame, which can achieve a more stable flipping.

[0021] 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 protection scope of the present utility model.

[0022] like Figures 1 to 5As shown, this utility model provides a flip-type double-sided automatic film applicator, including an applicator table 1. A fixed limiting block 2 is fixedly installed on the upper surface of the applicator table 1. A movable block 3 is movably connected to the upper part of the fixed limiting block 2. A threaded rod 4 is rotatably connected inside the movable block 3. A knob 5 is fixedly connected to the front end of the threaded rod 4. A baffle 6 is rotatably connected to the rear end of the threaded rod 4. A limiting rod 7 is fixedly connected to the rear surface of the movable block 3. The surface of the limiting rod 7 is movably connected to the interior of the baffle 6. A ball bearing 8 is fixedly installed at the rear of the baffle 6. A material feeding structure is provided on the upper part of the applicator table 1.

[0023] When the worker places the film roll on the surface where the upper mounting shaft 25 is installed, and the take-up roll is placed on the surface where the lower mounting shaft 25 is installed, the ball bearing 8 is initially located at the leftmost part of the fixed limit block 2. After the film roll and the take-up roll are placed on the surface where the mounting shaft 25 is installed, the moving block 3 is moved to the right. The moving block 3 moves left and right along the upper surface of the fixed limit block 2 to adjust its position. Then, the knob 5 is turned, which drives the threaded rod 4 to rotate, thereby adjusting the position of the baffle 6 so that the ball bearing 8 is in contact with the front surface of the film roll and the take-up roll. However, the limit rod 7 limits the movement of the ball bearing 8.

[0024] The upper surface of the film application table 1 is fixedly connected to a fixing frame 9. A first motor 10 is fixedly installed on the upper part of the fixing frame 9. The output shaft of the first motor 10 is fixedly connected to a rotating frame 11. A bidirectional threaded rod 12 is rotatably connected inside the rotating frame 11. A first gear 13 is fixedly sleeved on the surface of the bidirectional threaded rod 12. A rack 14 is movably connected to the surface of the rotating frame 11. The rack 14 and the first gear 13 mesh with each other. A drive structure is provided in the middle of the fixing frame 9. A clamping structure is provided on the surface of the bidirectional threaded rod 12.

[0025] After one side of the glass sheet 21 is coated with film, since the clamping assembly 20 remains in a clamping state, the first motor 10 is activated. The rotation of the output shaft of the first motor 10 drives the rotation of the rotating frame 11, which in turn drives the rotation of the bidirectional threaded rod 12, the first gear 13, and the clamping assembly 20, allowing the glass sheet 21 to be flipped. Then, the second motor 18 is activated. The rotation of the output shaft of the second motor 18 drives the rotation of the worm gear 19. Since the worm gear 19 meshes with the worm 16, it drives the rotating shaft 15 located inside the coating stage 1 to rotate. However, because the second gear 17 and the rack 14 interact with each other, the rack 14 is driven to move backward along the surface of the rotating frame 11, which in turn drives the first gear 13 to rotate, thereby realizing the rotation of the bidirectional threaded rod 12, which in turn drives the clamping assembly 20 to clamp the glass sheet 21. Before the first motor 10 starts, the electric push rod 23 starts, thereby driving the bracket 22 to descend, thus providing space for the rotation of the glass sheet 21. When the glass sheet 21 needs to be coated, the output axis of the electric push rod 23 moves upward, thereby making the bracket 22 provide a supporting force for the glass sheet 21.

[0026] The drive structure includes a rotating shaft 15 rotatably connected to the upper part of the film application table 1, a turbine 16 fixedly sleeved on the surface of the rotating shaft 15, a second gear 17 fixedly sleeved on the surface of the rotating shaft 15, the second gear 17 meshing with the rack 14, a second motor 18 fixedly installed in the middle of the fixing frame 9, and a worm gear 19 fixedly connected to the output shaft of the second motor 18, the worm gear 19 meshing with the turbine 16.

[0027] The second motor 18 is started, which drives the worm gear 19 to rotate. Then, due to the meshing of the worm gear 19 and the turbine 16, the rotating shaft 15 is driven to rotate, which in turn drives the second gear 17 to rotate. Then, due to the meshing of the two gears 17, the rack 14 moves back and forth along the surface of the rotating frame 11, which drives the first gear 13 to rotate, thereby realizing the clamping assembly 20 clamping the glass sheet 21.

[0028] The clamping structure includes a clamping assembly 20 threaded to the surface of a bidirectional threaded rod 12. The interior of the clamping assembly 20 is movably connected to the surface of the rotating frame 11. A glass sheet 21 is movably connected to the inside of the clamping assembly 20. A bracket 22 is provided below the glass sheet 21. An electric push rod 23 is fixedly connected to the lower surface of the bracket 22. The lower part of the electric push rod 23 is fixedly connected to the upper surface of the film application table 1. The surface of the bracket 22 is movably connected to the interior of the film application table 1.

[0029] The rotation of the first gear 13 drives the rotation of the bidirectional threaded rod 12. Since the bidirectional threaded rod 12 is threadedly connected to the clamping assembly 20, and the clamping assembly 20 is limited by the rotating frame 11, the clamping assembly 20 can move up and down, thereby clamping the glass sheet 21.

[0030] The feeding structure includes a film applicator 24 fixedly connected to the upper surface of the film applicator 1. The film applicator 24 is rotatably connected to a mounting shaft 25. A third motor 26 is fixedly installed on the upper part of the film applicator 24. The output shaft of the third motor 26 is fixedly connected to the rear end of the upper mounting shaft 25. A belt 27 is connected between the upper and lower mounting shafts 25 for transmission. An electric rotating rod 28 is fixedly installed on the front surface of the film applicator 24.

[0031] The film applicator 24 provides mounting points, and the rotation of the output shaft of the third motor 26 drives the upper mounting shaft 25 to rotate. The belt 27 drives the lower mounting shaft 25 to rotate at the same speed. The film roll is placed on the surface of the upper mounting shaft 25, and the film collection roll is placed on the surface of the lower mounting shaft 25. The film is sucked away by the film suction assembly 32 on the upper surface of the middle part of the film applicator 24. The film collection roll is collected from the lower mounting shaft 25 with the assistance of the rotation of the electric rotating rod 28.

[0032] The upper surface of the film applicator 24 is fixedly equipped with a transverse movement device 29, and the transverse movement device 29 is internally threaded with a moving plate 30.

[0033] The movement of the moving plate 30 is achieved by the transverse movement device 29. The transverse movement device 29 utilizes a motor, a threaded rod, and a limiting structure to achieve the left and right movement of the moving plate 30, thereby satisfying the movement of the membrane.

[0034] Among them, a cylinder 31 is fixedly installed on the upper part of the moving plate 30, a film suction assembly 32 is fixedly installed on the output shaft of the cylinder 31, and a film scraping device 33 is fixedly installed on the upper left surface of the film suction assembly 32.

[0035] The film is lifted and lowered by cylinder 31 and moved by transverse device 29 to achieve film application. However, the film suction assembly 32 uses vacuum suction to achieve film adsorption. The film scraping device 33 uses cylinder and rotating roller to scrape and press the applied film, thereby expelling air bubbles between the film and the glass sheet 21.

[0036] Working principle and usage process of this utility model:

[0037] When the worker places the film roll on the surface where the upper mounting shaft 25 is installed, and the take-up roll is placed on the surface where the lower mounting shaft 25 is installed, the ball bearing 8 is initially located at the leftmost part of the fixed limit block 2. After the film roll and the take-up roll are placed on the surface where the mounting shaft 25 is installed, the moving block 3 is moved to the right. The moving block 3 moves left and right along the upper surface of the fixed limit block 2 to adjust its position. Then, the knob 5 is turned, which drives the threaded rod 4 to rotate, thereby adjusting the position of the baffle 6 so that the ball bearing 8 is in contact with the front surface of the film roll and the take-up roll. However, the limit rod 7 limits the movement of the ball bearing 8.

[0038] After one side of the glass sheet 21 is coated with film, since the clamping assembly 20 remains in a clamping state, the first motor 10 is activated. The rotation of the output shaft of the first motor 10 drives the rotation of the rotating frame 11, which in turn drives the rotation of the bidirectional threaded rod 12, the first gear 13, and the clamping assembly 20, allowing the glass sheet 21 to be flipped. Then, the second motor 18 is activated. The rotation of the output shaft of the second motor 18 drives the rotation of the worm gear 19. Since the worm gear 19 meshes with the worm 16, it drives the rotating shaft 15 located inside the coating stage 1 to rotate. However, because the second gear 17 and the rack 14 interact with each other, the rack 14 is driven to move backward along the surface of the rotating frame 11, which in turn drives the first gear 13 to rotate, thereby realizing the rotation of the bidirectional threaded rod 12, which in turn drives the clamping assembly 20 to clamp the glass sheet 21. Before the first motor 10 starts, the electric push rod 23 starts, thereby driving the bracket 22 to descend, thus providing space for the rotation of the glass sheet 21. When the glass sheet 21 needs to be coated, the output axis of the electric push rod 23 moves upward, thereby making the bracket 22 provide a supporting force for the glass sheet 21.

[0039] The second motor 18 is started, which drives the worm gear 19 to rotate. Then, due to the meshing of the worm gear 19 and the turbine 16, the rotating shaft 15 is driven to rotate, which in turn drives the second gear 17 to rotate. Then, due to the meshing of the two gears 17, the rack 14 moves back and forth along the surface of the rotating frame 11, which drives the first gear 13 to rotate, thereby realizing the clamping assembly 20 clamping the glass sheet 21.

[0040] The rotation of the first gear 13 drives the rotation of the bidirectional threaded rod 12. Since the bidirectional threaded rod 12 is threadedly connected to the clamping assembly 20, and the clamping assembly 20 is limited by the rotating frame 11, the clamping assembly 20 can move up and down, thereby clamping the glass sheet 21.

[0041] The film applicator 24 provides mounting points, and the rotation of the output shaft of the third motor 26 drives the upper mounting shaft 25 to rotate. The belt 27 drives the lower mounting shaft 25 to rotate at the same speed. The film roll is placed on the surface of the upper mounting shaft 25, and the film collection roll is placed on the surface of the lower mounting shaft 25. The film is sucked away by the film suction assembly 32 on the upper surface of the middle part of the film applicator 24. The film collection roll is collected from the lower mounting shaft 25 with the assistance of the rotation of the electric rotating rod 28.

[0042] The movement of the moving plate 30 is achieved by the transverse movement device 29. The transverse movement device 29 utilizes a motor, a threaded rod, and a limiting structure to achieve the left and right movement of the moving plate 30, thereby satisfying the movement of the membrane.

[0043] The film is lifted and lowered by cylinder 31 and moved by transverse device 29 to achieve film application. However, the film suction assembly 32 uses vacuum suction to achieve film adsorption. The film scraping device 33 uses cylinder and rotating roller to scrape and press the applied film, thereby expelling air bubbles between the film and the glass sheet 21.
