Description

Technical Field

[0001] This utility model relates to the field of packaging machine technology, and in particular to a film correction mechanism for a packaging machine. Background Technology

[0002] Packaging machines are machines that package products to protect and enhance their appearance. They can be divided into two main categories: assembly line-style integrated production packaging and product peripheral packaging equipment.

[0003] Patent application number 201920537770.8 discloses an automatic film feeding correction mechanism for a packaging machine, which may include a film feeding bracket, a correction sensor, and a correction drive device. The film feeding bracket is mounted on the frame of the packaging machine and has a horizontal portion, which can be moved left and right. The correction sensor is mounted on the frame and located above the horizontal portion, and is used to detect whether the film is deviated. The correction drive device is mounted on the frame to the left or right of the film feeding bracket and is used to drive the film feeding bracket to move left or right according to the signal of the correction sensor, so as to realize the automatic correction of film feeding deviation.

[0004] However, traditional packaging machines often use a film roll translation method for their film correction mechanism. But when the film needs to be turned 90 degrees during the film feeding process, the film roll translation method is less effective for correction. For example, the film may shift during the film feeding process, which requires the packaging machine to have a film correction function. Currently, the correction function of packaging machines mainly uses the film roll translation method. When the film feeds and turns 90 degrees, the film roll translation method is not effective for correction. Utility Model Content

[0005] This utility model discloses a film correction mechanism for a packaging machine, which aims to solve the technical problem that the traditional film correction mechanism of a packaging machine often uses a translational film roll method, but the correction effect is poor when the film needs to be turned 90 degrees during the film feeding process.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A film correction mechanism for a packaging machine includes a mounting plate, two mounting plates, and a film, and further includes:

[0008] Testing mechanism: used to detect the edge position of the film;

[0009] A fixing plate is installed on one outer wall of the mounting plate. A motor base is installed on the top outer wall of the fixing plate. A servo motor is installed on the inner wall of the motor base. One end of the output shaft of the servo motor is connected to a drive gear. A rotating shaft is installed on the inner wall of the fixing plate. A driven gear is installed at the top of the rotating shaft. A swing seat is connected to the bottom of the rotating shaft. Three film alignment rollers are installed on the inner wall of the opposite side of the swing seat. The film is wound around the three film alignment rollers respectively.

[0010] In this scheme, when the detection mechanism detects the film position deflection, the servo motor works, driving the active gear to rotate, which in turn drives the passive gear to rotate. Under the rotation of the rotating shaft, the swing seat swings, causing the film alignment roller connected to the swing seat to swing. By swinging the angle of the film alignment roller, the film alignment is effectively corrected.

[0011] Optionally, the driving gear and the driven gear mesh.

[0012] Using the above technical solution, the servo motor directly drives the active gear to rotate, and the passive gear is mounted on the rotating shaft and meshes with the active gear. Thus, the rotation of the active gear can drive the passive gear to rotate simultaneously, resulting in a good linkage effect.

[0013] In a preferred embodiment, the detection mechanism includes a mounting block installed on one outer wall of the mounting plate, a fixing sleeve fitted on the outer wall of the mounting block, an adjusting screw connected to one inner wall of the fixing sleeve, a connecting block at one end of the adjusting screw, an ultrasonic sensor on one outer wall of the connecting block, and two membrane guide rollers on the opposite outer wall of the mounting plate, with the thin film wound around the two membrane guide rollers respectively.

[0014] Using the above technical solution, the ultrasonic sensor can detect the edge position of the film, thereby determining whether the film has deviated. The film alignment roller swings at a certain angle according to the signal from the ultrasonic sensor, thereby moving the film to the correct position.

[0015] As can be seen from the above, a film correction mechanism for a packaging machine includes a mounting plate, two mounting plates, and a film, and also includes:

[0016] Testing mechanism: used to detect the edge position of the film;

[0017] A fixing plate is installed on one outer wall of the mounting plate. A motor base is installed on the top outer wall of the fixing plate. A servo motor is installed on the inner wall of the motor base. One end of the output shaft of the servo motor is connected to a drive gear. A rotating shaft is installed on the inner wall of the fixing plate. A driven gear is installed at the top of the rotating shaft. A swing seat is connected to the bottom of the rotating shaft. Three film-correcting rollers are installed on the inner wall of the opposite side of the swing seat. The film is wound around the three film-correcting rollers respectively. The film-correcting mechanism of the packaging machine provided by this utility model uses an ultrasonic sensor to detect the edge position of the film to determine whether the film is deviated. Then, by swinging the angle of the film-correcting rollers, the film is effectively corrected. Attached Figure Description

[0023] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. The components of the embodiments of this application described and marked in the accompanying drawings can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of this application provided in the accompanying drawings is not intended to limit the scope of the claimed application, but merely represents selected embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application.

[0024] The film correction mechanism of the packaging machine disclosed in this utility model is mainly used in traditional packaging machines. When the film correction mechanism is used, it often adopts the method of translating the film roll. However, when the film needs to be turned 90 degrees during the film feeding process, the correction effect of the method of translating the film roll is poor.

[0025] Reference Figure 1 , Figure 2 and Figure 4 A film correction mechanism for a packaging machine includes a mounting plate 1, two mounting plates 2, and a film 10, and further includes:

[0026] Testing agency: Used to detect the edge position of film 10;

[0027] A fixing plate 6 is fixedly installed on one side of the outer wall of the mounting plate 1. A motor base 3 is fixedly installed on the top outer wall of the fixing plate 6. A servo motor 11 is provided on the inner wall of the motor base 3. A drive gear 4 is fixedly connected to one end of the output shaft of the servo motor 11. A rotating shaft 12 is provided on the inner wall of the fixing plate 6. A driven gear 5 is provided at the top of the rotating shaft 12. A swing seat 7 is fixedly connected to the bottom of the rotating shaft 12. Three film correction rollers 8 are provided on the inner wall of the opposite side of the swing seat 7. The film 10 is respectively wound around the three film correction rollers 8.

[0028] In the specific working process, when the detection mechanism detects the deflection of the film 10, it sends a signal, the servo motor 11 works, drives the active gear 4 to rotate, thereby driving the passive gear 5 to rotate, causing the rotating shaft 12 inside the passive gear 5 to rotate at the same time, driving the swing seat 7 to swing in the opposite direction of the deflection position, thereby causing the film correction roller 8 connected to the swing seat 7 to swing for film correction.

[0029] Furthermore, refer to Figure 1 and Figure 2 In some instances, the driving gear 4 and the driven gear 5 mesh together, so that the servo motor 11 directly drives the driving gear 4 to rotate. The driven gear 5 is mounted on the rotating shaft 12 and meshes with the driving gear 4. Thus, the rotation of the driving gear 4 can drive the driven gear 5 to rotate simultaneously, providing power for the correction of the thin film 10.

[0030] The rotating shaft 12 is used in conjunction with the film alignment roller 8. The film alignment roller 8 is mounted on the rotating shaft 12. When the passive gear 5 rotates, the film alignment roller 8 will swing. By swinging the angle of the film alignment roller 8, the film 10 can be quickly aligned.

[0031] Reference Figure 1 , Figure 3 and Figure 4In a preferred embodiment, the detection mechanism includes a mounting block 13 fixedly mounted on one side of the outer wall of a mounting plate 2. A fixing sleeve 14 is sleeved on the outer wall of the mounting block 13. An adjusting screw is connected to one side of the inner wall of the fixing sleeve 14. A connecting block 15 is provided at one end of the adjusting screw. An ultrasonic sensor 16 is provided on one side of the outer wall of the connecting block 15. Two membrane guide rollers 9 are provided on the opposite side of the outer walls of the two mounting plates 2. The film 10 is respectively wound around the two membrane guide rollers 9.

[0032] Specifically, the ultrasonic sensor 16 is installed between the two membrane guide rollers 9, which can detect the edge position of the film 10, thereby determining whether the film 10 has deviated and in which direction. Then, based on the signal from the ultrasonic sensor 16, the film correction roller 8 is swung at a certain angle, thereby translating the film 10 to the correct position.

[0033] The ultrasonic sensor 16 works in conjunction with the film 10. When the film 10 is wound around the two film guide rollers 9, the ultrasonic sensor 16 detects the edge position of the film 10 to determine whether the position of the film 10 has deviated, and then performs certain correction adjustments.

[0034] Reference Figure 4 In a preferred embodiment, the three film alignment rollers 8 and the two film guide rollers 9 are used in conjunction with the film 10.

[0035] Specifically, the film 10 is sequentially wound around three film alignment rollers 8 and two film guide rollers 9, and is conveyed from the direction of the film alignment rollers 8 to the position of the film guide rollers 9. The film 10 is wound from the top of the two film alignment rollers 8 on both sides, wound at the bottom of the film alignment roller 8 in the middle position, then wound to the bottom of the film guide roller 9 near the film alignment roller 8, and then wound to the top of the last film guide roller 9, so that the film 10 is conveyed. During the conveying process, a certain film alignment angle is adjusted.

[0036] Working principle: In use, the membrane correction mechanism consists of a drive gear 4, a driven gear 5, a rotating shaft 12, a membrane correction roller 8, a membrane guide roller 9, and an ultrasonic sensor 16. The membrane 10 is sequentially wound around the three membrane correction rollers 8 and the two membrane guide rollers 9. The ultrasonic sensor 16 detects whether the edge of the membrane 10 is deviated and then transmits a signal. When the membrane 10 is deviated, the servo motor 11 works and drives the drive gear 4 to rotate. Since the drive gear 4 meshes with the driven gear 5, it drives the driven gear 5 to rotate. Under the rotation of the rotating shaft 12, the swing seat 7 swings in the opposite direction of the deviated position, causing the membrane correction roller 8 connected to the swing seat 7 to swing. By swinging the membrane correction roller 8, the membrane 10 is corrected.

[0037] The above description is merely a preferred embodiment of this utility model, but the protection scope of this utility model is not limited thereto. The substitutions may be replacements of some structures, devices, or method steps, or they may be complete technical solutions. Equivalent substitutions or modifications made based on the technical solution and inventive concept of this utility model should all be covered within the protection scope of this utility model.
