Description

Technical Field

[0001] This utility model relates to the field of packaging machine technology, and more specifically, to a film guiding and correction device for automatic packaging machines. Background Technology

[0002] Automatic packaging machines are mechanical equipment that can automatically complete the product packaging process. They are widely used in industries such as food, pharmaceuticals, daily chemicals, electronics, and chemicals. By integrating mechanical, electrical, pneumatic, sensor, and control system technologies, they achieve fully automated operation from material supply, metering, filling, sealing to finished product output, significantly improving production efficiency, reducing labor costs, and ensuring packaging quality.

[0003] In actual use, the film is prone to adsorbing impurities such as dust, oil or adhesive particles during production or transportation. These impurities affect the coefficient of friction of the film surface, which in turn affects the transmission of the film, causing it to deviate during transport. Furthermore, the correction roller will also slip due to the influence of impurities during correction, which will affect the correction accuracy of the correction roller. Utility Model Content

[0004] In order to overcome the above-mentioned defects of the prior art, the present invention provides a film guiding and correction device for an automatic packaging machine to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: An automatic packaging machine film guiding and correction device includes a support frame mounted on the packaging machine body, a fixed frame fixedly connected to one side of the support frame, a cleaning component mounted on the fixed frame, and a correction mechanism mounted on the support frame. The cleaning assembly includes two tension rollers, which are rotatably connected to the interior of a fixed frame. A first variable frequency motor is fixedly connected to one side of the fixed frame, and a cleaning roller is fixedly connected to the output end of the first variable frequency motor. The cleaning roller is rotatably connected to the interior of the tension roller. Multiple brush strips are fixedly connected to the outer side of the cleaning roller, and multiple dust collection hoppers are connected to the outer side of the cleaning roller. A dust collection groove is opened inside the cleaning roller. A deviation correction sensor is installed on one side of the support frame, and a vacuum cleaner is installed on one side of the packaging machine body. Both output ends of the vacuum cleaner are connected to suction pipes, which pass through the tension roller and extend into the interior of the cleaning roller. The suction pipes are rotatably connected to the interior of the cleaning roller.

[0006] By adopting the above technical solution, stable tension can be maintained during film transport, and the film surface can be cleaned, reducing the adsorption of impurities on the film surface.

[0007] As a further description of the above technical solution: the correction mechanism includes two slide grooves, which are formed at the top of the support frame. A movable frame is provided at the top of the support frame, and the movable frame is slidably connected to the inner side of the slide groove. An electric push rod is installed on one side of the movable frame, and a connecting frame is fixedly connected to the output end of the electric push rod. One end of the connecting frame is fixedly connected to the movable frame. A second variable frequency motor is installed on one side of the movable frame, and a first correction roller is fixedly connected to the output end of the second variable frequency motor. The first correction roller is rotatably connected to the inner side of the movable frame. A second correction roller is provided on the inner side of the support frame, and rotating brackets are rotatably connected to both ends of the second correction roller.

[0009] The technical effects and advantages of this utility model are as follows: 1. By setting up a cleaning component, compared with the existing technology, the two tension rollers can enable the film to maintain a stable tension, and the two cleaning rollers rotate in opposite directions. Then, by brushing, impurities can be cleaned while the film tension is kept stable, so as to reduce the large displacement of the film caused by impurities during the film transport process, and reduce the adsorption of impurities on the film surface. 2. By setting up a correction mechanism, compared with the existing technology, dynamic correction can be performed by moving the first correction roller, and the second correction roller can be adjusted up and down to clamp the film, thereby forming a combined effect of clamping and correction.

[0018] 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.

[0019] The embodiments disclosed in this application are as follows: Figure 1-5 The automatic packaging machine film guiding and correction device shown includes a support frame 2 set on the packaging machine body 1. The support frame 2 is fixedly connected to the top of the packaging machine body 1, and a fixed frame 3 is fixedly connected to one side of the support frame 2. A cleaning component is installed on the fixed frame 3, and a correction mechanism is installed on the support frame 2. The cleaning assembly includes two tension rollers 4, which are rotatably connected to the inside of a fixed frame 3. A first variable frequency motor 5 is fixedly connected to one side of the fixed frame 3, and a cleaning roller 6 is fixedly connected to the output end of the first variable frequency motor 5. The cleaning roller 6 is rotatably connected to the inside of the tension rollers 4. Multiple brush strips 7 are fixedly connected to the outside of the cleaning roller 6, and multiple dust collection hoppers 8 are connected to the outside of the cleaning roller 6. A dust collection groove 9 is opened inside the cleaning roller 6. A deviation correction sensor is installed on one side of the support frame, and a vacuum cleaner 11 is installed on one side of the packaging machine body 1. Both output ends of the vacuum cleaner 11 are connected to suction pipes 10, which penetrate the tension rollers 4 and extend into the inside of the cleaning roller 6 for dust collection. The tube 10 is rotatably connected to the cleaning roller 6. The rotation of the two tension rollers 4 allows the film to maintain stable tension during transport. The first variable frequency motor 5 drives the cleaning roller 6 to rotate, allowing the two cleaning rollers 6 to rotate in opposite directions on the outside of the film. This also drives the brush strips 7 and the dust collection bucket 8 to rotate. Under the action of the vacuum cleaner 11, the multiple brush strips 7 sweep away the impurities on the film surface, and the dust collection bucket 8 adsorbs the impurities, thereby collecting the swept impurities. This reduces the large-scale displacement of the film caused by impurities during the film transport process and reduces the adsorption of impurities on the film surface.

[0020] Reference Figure 6 and 7As shown, the correction mechanism includes two slides 12, which are formed at the top of the support frame 2. A movable frame 13 is provided at the top of the support frame 2, and the movable frame 13 is slidably connected to the inner side of the slides 12. An electric push rod 14 is installed on one side of the movable frame 13, and a connecting frame 15 is fixedly connected to the output end of the electric push rod 14. One end of the connecting frame 15 is fixedly connected to the movable frame 13. A second variable frequency motor 16 is installed on one side of the movable frame 13, and a first correction roller 17 is fixedly connected to the output end of the second variable frequency motor 16. The first correction roller 17 is rotatably connected to the inner side of the movable frame 13. A second correction roller 18 is provided inside the support frame 2, and a rotating bracket 19 is rotatably connected to both ends of the second correction roller 18. A guide post 20 is slidably connected inside one of the rotating brackets 19. A turntable 21 is rotatably connected inside the support frame 2, and a first bevel gear 22 is fixedly connected to one end of the turntable 21. A second bevel gear 23 meshes with one side of the first bevel gear 22, and a threaded rod 24 is fixedly connected to the top of the second bevel gear 23. 4. The connecting frame 15 is rotatably connected to the support frame 2. The outer side of the threaded rod 24 is threadedly connected to the inner side of another rotating bracket 19. The connecting frame 15 is pushed to move back and forth by the electric push rod 14. The connecting frame 15 can pull the movable frame 13 to drive the first correction roller 17 to move. The reciprocating movement of the first correction roller 17 can correct the position of the film, so that the position of the film can be kept stable. By rotating the turntable 21, the turntable 21 can drive the first bevel gear 22 to rotate. The first bevel gear 22 can mesh with the second bevel gear 23 to drive the threaded rod 24 to rotate. The thread action of the threaded rod 24 can drive one of the rotating brackets 19 to move. The rotating bracket 19 can drive the second correction roller 18 to move. This can adjust the gap between the first correction roller 17 and the second correction roller 18. Thus, while the first correction roller 17 corrects the position of the film, the second correction roller 18 can maintain a constant tension of the film, so as to improve the correction effect.

[0021] Working principle of this utility model: This utility model designs a film guiding and correction device for an automatic packaging machine. The specific structure is shown in the attached instruction manual. Figure 1-7 As shown, in this technical solution, through the cooperation between various structures, when the packaging machine body 1 is in use, the film passes through two tension rollers 4, the second variable frequency motor 16 and the first correction roller 17. When the film is being conveyed, the two tension rollers 4 can maintain the tension of the film on the outside of the film and start the two first variable frequency motors 5. The first variable frequency motors 5 drive the cleaning roller 6 to rotate, so that the cleaning roller 6 can drive the rotation of multiple brush strips 7 and dust collection buckets 8, which is opposite to the direction of film conveying. During the film conveying process, multiple brush strips 7 can sweep and clean the surface of the film, and start the vacuum cleaner 11. Two suction pipes 10 extend into the interior of the cleaning roller 6 and are rotatably connected to the interior of the cleaning roller 6. While the cleaning roller 6 is cleaning, it can collect the cleaned impurities through multiple dust collection buckets 8. When the film passes through the first alignment roller 17 and the second alignment roller 18, the turntable 21 is rotated, which drives the first bevel gear 22 to rotate. The first bevel gear 22 meshes with and drives the second bevel gear 23 to rotate. The second bevel gear 23 drives the threaded rod 24 to rotate. The threaded rod 24 is internally threadedly connected to one of the rotating supports 19, thus driving the rotating support 19 to move upwards when the threaded rod 24 rotates. The guide post 20 can slide inside the other rotating support 19, providing guidance for the movement of the second alignment roller 18. This allows the second alignment roller 18 to move stably alongside the first alignment roller 17, thereby ensuring proper alignment of the first alignment roller 18. The gap between the first correction roller 17 and the second correction roller 18 is adjusted, and the second variable frequency motor 16 is started. The second variable frequency motor 16 drives the first correction roller 17 to rotate, so that the first correction roller 17 can cooperate with the second correction roller 18 to assist in film conveying. When the film position is deviated, the correction sensor is used to judge and the electric push rod 14 is started. The electric push rod 14 pushes the connecting frame 15 to move, so that the connecting frame 15 can pull the movable frame 13 to drive the first correction roller 17 to move. The slide 12 can provide guidance for the movement of the movable frame 13, so that the first correction roller 17 can move back and forth to correct the film position.
