Abstract
Description
Technical Field
[0001] This utility model relates to the field of privacy film production technology, and in particular to a privacy film production receiving and counting device. Background Technology
[0002] Privacy screen protectors are a special type of screen protector primarily used on devices such as mobile phones, tablets, and computer monitors. They are designed to protect user privacy. Through special optical technology, the screen appears black or blurry when viewed from the side, but displays content clearly when viewed directly from the front. With the widespread use of portable electronic devices such as smartphones, tablets, and laptops, privacy screen protectors have gradually gained popularity as an effective privacy protection tool. During the production and collection process, privacy screen protectors require counting, necessitating a privacy screen protector production counting device.
[0003] In existing privacy film production processes, automated counting devices typically place the privacy films on a high-speed rotating conveyor belt and use sensors or mechanical counting systems for counting. However, the high speed of the rotating conveyor belt and the rapid movement of the privacy films can prevent the sensors or mechanical counting systems from accurately capturing the passage of each film. This can lead to missed or incorrect counts, affecting the accuracy of production data. Furthermore, a collection container is installed at one end of the conveyor belt to catch falling privacy films. However, during high-speed movement, these films may fall directly into the collection container, potentially colliding with each other. Such collisions can cause edge damage, scratches, or deformation, and may also affect optical performance and usability, ultimately reducing the overall quality of the product. Utility Model Content
[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a counting device for receiving materials in the production of privacy film.
[0005] To achieve the above objectives, the present invention adopts the following technical solution:
[0006] A device for counting and collecting materials in the production of privacy films includes a base. Columns are fixed at the four corners of the base's top. A top plate is fixed to the top of each of the four columns. Support plates are fixed to both ends of the top of the top plate. A first conveyor belt is installed at one end of the inner sidewall of two of the support plates, and a second conveyor belt is installed at the other end of the inner sidewall of the two support plates, with the second conveyor belt located below the first conveyor belt. A rotating mechanism for rotating the first and second conveyor belts is provided on the top of the base. A collection box is fixed to one sidewall of the base and the top plate. A connecting plate is slidably connected to the inner sidewall of the collection box. The sidewall of the collection box is provided with… The lifting mechanism for the lifting connecting plate has the same U-shaped frame fixed to the top of the two support plates. A photoelectric sensor is installed at the bottom of the U-shaped frame and is located above the junction of the first and second conveyor belts. The inner sidewalls of the two support plates are provided with an anti-deviation mechanism to prevent the privacy film from shifting. During use, due to the speed difference between the first and second conveyor belts, the privacy film gradually decreases in speed when it enters the top of the second conveyor belt and is distributed in a stepped manner. With the help of the photoelectric sensor, the number of privacy films passing by can be recorded in real time, thereby improving the accuracy of the data and avoiding omissions or miscounts.
[0007] Preferably, the rotating mechanism includes two first rotating shafts, which are disposed through one of the support plate sidewalls. The two ends of the first conveyor belt are respectively sleeved on the sidewalls of the two first rotating shafts. A second pulley is sleeved on one sidewall of one of the first rotating shafts. Two second rotating shafts are disposed on the inner sidewalls of the two support plates. One end of one second rotating shaft is disposed through the outer sidewall of one support plate, and the other end of the second second rotating shaft is disposed through the outer sidewall of the other support plate. The two ends of the second conveyor belt are respectively sleeved on the sidewalls of the two second rotating shafts. A first pulley is sleeved on one end of one of the second rotating shafts, and the diameter of the first pulley is larger than the diameter of the second pulley. A first toothed belt is disposed on the top of the base, and the two ends of the first toothed belt are respectively sleeved on the second pulley and the sidewall of the first pulley. A motor is fixed to the outer sidewall of one of the support plates, and the output shaft of the motor is fixed to one of the second rotating shafts. The motor drives one of the second rotating shafts to rotate, cooperating with the other second rotating shaft to rotate. When one of the second rotating shafts rotates, it drives the first pulley to rotate. The first toothed belt and the second pulley drive one of the first shafts to rotate, which in turn drives the first conveyor belt to rotate. Since the diameter of the first pulley is larger than that of the second pulley, the rotational speed of the first conveyor belt is greater than that of the second conveyor belt. When the privacy film is conveyed from the top of the first conveyor belt to the top of the second conveyor belt, due to the speed difference, the privacy film entering the top of the second conveyor belt has a slower speed, while the privacy film on the first conveyor belt has a faster speed. As the privacy film is continuously conveyed, it is stacked sequentially and distributed in a stepped manner. Since the photoelectric sensor is electrically connected to the controller, when the privacy film passes the bottom of the photoelectric sensor, it will block the light beam emitted by the photoelectric sensor, thereby triggering the counting signal of the photoelectric sensor and transmitting the signal to the controller. Each time the light beam is blocked, the sensor generates a pulse signal. The control system receives the pulse and counts it. By accumulating the signals, the number of privacy films that have passed can be recorded in real time. By reducing the conveying speed of the privacy film, the counting system can effectively prevent missed or incorrect counting, thereby improving the accuracy of the data.
[0008] Preferably, one end of another second rotating shaft is fitted with a third pulley, the base sidewall is rotatably connected to the third rotating shaft, the sidewall of the third rotating shaft is fitted with a composite pulley, the base sidewall is provided with a second toothed belt, and the two ends of the second toothed belt are respectively fitted onto the sidewalls of the third pulley and the composite pulley, the collection box sidewall is rotatably connected to a fourth rotating shaft, the sidewall of the fourth rotating shaft is fitted with a connecting plate, the outer sidewall of the collection box is provided with a third toothed belt, and the two ends of the third toothed belt are respectively fitted onto the sidewalls of the composite pulley and the connecting plate. Above, a first bevel gear is sleeved on the side wall of the fourth rotating shaft. The lifting mechanism includes two first support plates, which are symmetrically fixed to one end of the outer wall of the collection box. A lead screw is rotatably connected to the inner side wall of the two first support plates, and one end of the lead screw passes through the bottom of one of the first support plates. A second bevel gear is sleeved on the bottom side wall of the lead screw, and the second bevel gear meshes with the first bevel gear. Two second support plates are symmetrically fixed to the other end of the collection box, and the same sliding rod is fixed to the inner side wall of the two second support plates. The collection box has symmetrical grooves on both outer side walls. One groove side wall is fitted with a lead screw nut, one end of which is sleeved on the lead screw side wall, and the other end is fixed to a connecting plate. The lead screw nut and lead screw are compatible. The other groove side wall is fitted with a slider, one end of which is sleeved on the slider side wall, and the other end is fixed to the connecting plate. As the second conveyor belt rotates, the privacy film is gradually conveyed to the top of the collection box, coordinating with the third pulley, the second toothed belt, and the composite pulley to drive the third rotating shaft to rotate. The rotation of the third shaft, in conjunction with the composite pulley, the third toothed belt, and the connecting plate, drives the fourth shaft to rotate. The rotation of the fourth shaft, in conjunction with the first and second bevel gears, drives the lead screw to rotate. The rotation of the lead screw, in conjunction with the lead screw nut, causes the connecting plate to slowly descend along the inner wall of the collection box under the constraint of the slide bar and the slider. This allows the privacy film to be gradually stacked and collected inside the collection box, preventing the privacy film from falling directly into the collection box and avoiding collisions between the privacy films that could cause edge damage, scratches, or deformation, thus improving the overall quality of the privacy film.
[0009] Preferably, the anti-deviation mechanism includes two rubber plates symmetrically arranged on the inner sidewalls of two support plates, and both rubber plates are located above the first conveyor belt. Two electric telescopic rods symmetrically pass through the outer sidewalls at both ends of the two support plates. The telescopic ends of the four electric telescopic rods are fixed to the two rubber plates in pairs. Driving the four electric telescopic rods causes the two rubber plates to move closer or further apart, so that the two rubber plates are close to the two ends of the privacy film, avoiding collision between the privacy film and the two support plates during the conveying process, and ensuring the stability and safety of the privacy film.
[0010] Preferably, casters are installed at all four corners of the base, which facilitates the movement of the device.
[0011] The beneficial effects of this utility model are as follows:
[0012] 1. During use, due to the speed difference between the first and second conveyor belts, the privacy film gradually slows down as it enters the top of the second conveyor belt and is distributed in a stepped manner. Combined with photoelectric sensors, the number of privacy films passing by can be recorded in real time, thereby improving the accuracy of the data and avoiding omissions or miscounts.
[0013] 2. When the privacy film is conveyed to the top of the connecting plate, the rotating mechanism and the lifting mechanism make the connecting plate gradually move downward along the inner wall of the collection box. This allows the privacy film to be gradually stacked and collected inside the collection box, preventing the privacy film from falling directly into the collection box and preventing the privacy film from colliding with each other, which would cause the edges of the film to be damaged, scratched or deformed, thus improving the overall quality of the privacy film.
[0014] 3. The anti-deviation mechanism effectively prevents the privacy film from colliding with the support plate during transportation, ensuring the stability and safety of the privacy film. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0023] Reference Figures 1-6 A device for counting and collecting materials in the production of privacy film includes a base 1. Columns 2 are fixed at the four corners of the top of the base 1. A top plate 3 is fixed to the top of the four columns 2. Support plates 5 are fixed to both ends of the top of the top plate 3. A first conveyor belt 9 is installed at one end of the inner wall of two support plates 5, and a second conveyor belt 10 is installed at the other end of the inner wall of the two support plates 5, with the second conveyor belt 10 located below the first conveyor belt 9. A rotating mechanism for rotating the first conveyor belt 9 and the second conveyor belt 10 is installed on the top of the base 1. A collection box 11 is fixed to one side wall of the base 1 and the top plate 3. A connecting plate 23 is slidably connected to the inner wall of the collection box 11. A useful... In the lifting mechanism of the lifting connecting plate 23, the top of the two support plates 5 are fixed with the same U-shaped frame 7. The bottom of the U-shaped frame 7 is equipped with a photoelectric sensor 34, and the photoelectric sensor 34 is located above the junction of the first conveyor belt 9 and the second conveyor belt 10. The inner sidewalls of the two support plates 5 are provided with an anti-deviation mechanism to prevent the privacy film from shifting. During the use of this device, due to the speed difference between the first conveyor belt 9 and the second conveyor belt 10, the speed of the privacy film gradually decreases when it enters the top of the second conveyor belt 10 and is distributed in a stepped manner. With the help of the photoelectric sensor 34, the number of privacy films passing by can be recorded in real time, thereby improving the accuracy of the data and avoiding omissions or miscounts.
[0024] Furthermore, the rotating mechanism includes two first rotating shafts 12, which are disposed through one of the support plates 5 sidewalls. The two ends of the first conveyor belt 9 are respectively fitted onto the sidewalls of the two first rotating shafts 12. A second pulley 14 is fitted onto one end of the sidewall of one of the first rotating shafts 12. Two second rotating shafts 13 are disposed on the inner sidewalls of the two support plates 5. One end of one second rotating shaft 13 is disposed through the outer sidewall of one of the support plates 5, and one end of the other second rotating shaft 13 is disposed through the outer sidewall of the other support plate 5. The two ends of the second conveyor belt 10 are respectively fitted onto the sidewalls of the two second rotating shafts 13. One end of a second rotating shaft 13 is fitted with a first pulley 15, and the diameter of the first pulley 15 is larger than the diameter of the second pulley 14. A first toothed belt 16 is provided on the top of the base 1, and the two ends of the first toothed belt 16 are respectively fitted onto the side walls of the second pulley 14 and the first pulley 15. A motor 6 is fixed to the outer wall of one of the support plates 5, and the output shaft of the motor 6 is fixed to one of the second rotating shafts 13. The drive motor 6 drives one of the second rotating shafts 13 to rotate, which in turn drives the other second rotating shaft 13 to rotate. When one of the second rotating shafts 13 rotates, it drives the first pulley 14. 5. Rotation, in conjunction with the first toothed belt 16 and the second pulley 14, drives one of the first rotating shafts 12 to rotate, which in turn drives the first conveyor belt 9 to rotate. Since the diameter of the first pulley 15 is larger than the diameter of the second pulley 14, the rotational speed of the first conveyor belt 9 is greater than that of the second conveyor belt 10. When the privacy film is conveyed from the top of the first conveyor belt 9 to one end of the top of the second conveyor belt 10, due to the speed difference, the privacy film entering the top of the second conveyor belt 10 has a slower speed, while the privacy film on the first conveyor belt 9 moves faster. As the privacy film is continuously conveyed, the privacy... The films are stacked sequentially in a stepped distribution. Since the photoelectric sensor 34 is electrically connected to the controller, when the privacy film passes the bottom of the photoelectric sensor 34, it will block the light beam emitted by the photoelectric sensor 34, thereby triggering the counting signal of the photoelectric sensor 34 and transmitting the signal to the controller. Each time the light beam is blocked, the sensor will generate a pulse signal. After receiving the pulse, the control system will count. By accumulating the signals, the number of privacy films that have passed can be recorded in real time. By reducing the conveying speed of the privacy film, the counting system can effectively prevent missed or incorrect counting, thereby improving the accuracy of the data.
[0025] Furthermore, a third pulley 17 is sleeved on one end of another second rotating shaft 13. A third rotating shaft 19 is rotatably connected to the side wall of the base 1. A composite pulley 20 is sleeved on the side wall of the third rotating shaft 19. A second toothed belt 18 is provided on the side wall of the base 1, and the two ends of the second toothed belt 18 are respectively sleeved on the side walls of the third pulley 17 and the composite pulley 20. A fourth rotating shaft 22 is rotatably connected to the side wall of the collection box 11. A connecting plate 23 is sleeved on the side wall of the fourth rotating shaft 22. A third toothed belt 21 is provided on the outer side wall of the collection box 11, and the two ends of the third toothed belt 21 are respectively sleeved on the side walls of the composite pulley 20 and the connecting plate 23. A first bevel gear 25 is sleeved on the side wall of the fourth rotating shaft 22. The lifting mechanism includes two first support plates 27, which are symmetrically fixed to one end of the outer side wall of the collection box 11. A lead screw 28 is rotatably connected to the inner side wall of the two first support plates 27, and one end of the lead screw 28 passes through the bottom of one of the first support plates 27. A second bevel gear 26 is sleeved on the bottom side wall of the lead screw 28, and the second bevel gear 26 meshes with the first bevel gear 25. Two second support plates 30 are symmetrically fixed to the other end of the collection box 11. The same slide rod 31 is fixed to the inner side wall of the two second support plates 30. Both outer side walls of the collection box 11 are symmetrically connected to the first bevel gear 25. A chute 24 is provided, one side wall of which is provided with a lead screw nut 29. One end of the lead screw nut 29 is sleeved on the side wall of the lead screw 28, and the other end of the lead screw nut 29 is fixed to the connecting plate 23. The lead screw nut 29 and the lead screw 28 are compatible. The other side wall of the chute 24 is provided with a slider 32. One end of the slider 32 is sleeved on the side wall of the slider 31, and the other end of the slider 32 is fixed to the connecting plate 23. As the second conveyor belt 10 rotates, the privacy film is gradually conveyed to the top of the collection box 11. In conjunction with the third pulley 17, the second toothed belt 18 and the composite pulley 20, the third rotating shaft 19 is driven to rotate. The rotating composite pulley 20, the third toothed belt 21, and the connecting plate 23 drive the fourth rotating shaft 22 to rotate. The rotation of the fourth rotating shaft 22, in conjunction with the first bevel gear 25 and the second bevel gear 26, drives the lead screw 28 to rotate. The rotation of the lead screw 28, in conjunction with the lead screw nut 29, causes the connecting plate 23 to slowly descend along the inner wall of the collection box 11 under the constraint of the slide bar 31 and the slider 32. This allows the privacy film to be gradually stacked and collected inside the collection box 11, preventing the privacy film from falling directly into the collection box 11 and avoiding collisions between the privacy films that could cause damage, scratches, or deformation to the edges of the film, thus improving the overall quality of the privacy film.
[0026] Furthermore, the anti-deviation mechanism includes two rubber plates 8, which are symmetrically arranged on the inner sidewalls of the two support plates 5, and both rubber plates 8 are located above the first conveyor belt 9. Two electric telescopic rods 33 are symmetrically inserted through the outer sidewalls at both ends of the two support plates 5. The telescopic ends of the four electric telescopic rods 33 are fixed to the two rubber plates 8 in pairs. Driving the four electric telescopic rods 33 will cause the two rubber plates 8 to move closer or further away from each other, so that the two rubber plates 8 are close to the two ends of the privacy film, avoiding collision between the privacy film and the two support plates 5 during the conveying process, and ensuring the stability and safety of the privacy film.
[0027] Furthermore, casters 4 are installed at the four corners of the bottom of the base 1, which facilitates the movement of the device.
[0028] Working Principle: During use, the distance between the two rubber plates 8 is adjusted according to the specifications of the privacy film during transport. Simultaneously, the power switches of the four electric telescopic rods 33 are turned on, driving them to move the two rubber plates 8 closer or further apart, ensuring they are close to both ends of the privacy film. This prevents the privacy film from colliding with the two support plates 5 during transport. The privacy film is then placed one by one at the top end of the first conveyor belt 9 using other transport equipment. During counting, the power switch of the motor 6 is turned on, driving one of the second rotating shafts 13 to rotate, which in turn rotates the other second rotating shaft 13. When the rotating shaft 13 rotates, it drives the first pulley 15 to rotate. This, in conjunction with the first toothed belt 16 and the second pulley 14, drives one of the first rotating shafts 12 to rotate. The other first rotating shaft 12, in turn, drives the first conveyor belt 9 to rotate. Because the diameter of the first pulley 15 is larger than the diameter of the second pulley 14, the rotational speed of the first conveyor belt 9 is greater than that of the second conveyor belt 10. When the privacy film is conveyed from the top of the first conveyor belt 9 to one end of the top of the second conveyor belt 10, due to the speed difference, the privacy film entering the top of the second conveyor belt 10 slows down, while the privacy film on the first conveyor belt 9 moves faster. As the privacy film is continuously conveyed, it stacks up sequentially in a stepped distribution. Due to photoelectric... Sensor 34 is electrically connected to a controller. When the privacy film passes the bottom of photoelectric sensor 34, it blocks the light beam emitted by photoelectric sensor 34, thereby triggering the counting signal of photoelectric sensor 34 and transmitting the signal to the controller. Each time the light beam is blocked, the sensor generates a pulse signal. The control system counts the pulses received. By accumulating the signals, the number of privacy films that have passed can be recorded in real time. By reducing the conveying speed of the privacy film, the counting system can effectively prevent missed or incorrect counts, thereby improving the accuracy of the data. As the second conveyor belt 10 rotates, the privacy film is gradually conveyed to the top of the collection box 11, cooperating with the third pulley 17, the second toothed belt 18, and... The composite pulley 20 drives the third rotating shaft 19 to rotate. The rotation of the third rotating shaft 19, in conjunction with the composite pulley 20, the third toothed belt 21, and the connecting plate 23, drives the fourth rotating shaft 22 to rotate. The rotation of the fourth rotating shaft 22, in conjunction with the first bevel gear 25 and the second bevel gear 26, drives the lead screw 28 to rotate. The rotation of the lead screw 28, in conjunction with the lead screw nut 29, causes the connecting plate 23 to slowly descend along the inner wall of the collection box 11 under the constraint of the slide bar 31 and the slider 32. This allows the privacy film to be gradually stacked and collected inside the collection box 11, preventing the privacy film from falling directly into the collection box 11 and avoiding collisions between the privacy films that could cause edge damage, scratches, or deformation, thus improving the overall quality of the privacy film.
