[0041] During the implementation of the above-mentioned embodiment, the lifting mechanism 310 of the feeding mechanism 20 in this embodiment also includes a first sliding component 330 and a second sliding component 340, one end of the first sliding component 330 is connected to multiple unloading tables 200, the second conveyor belt 317 passes through the first sliding component 330, the second conveyor belt 317 is fixedly connected to the first sliding component 330, one end of the second sliding component 340 is connected to multiple unloading tables 200, the third conveyor belt 318 passes through the second sliding component 340, and the third conveyor belt 318 is fixedly connected to the second sliding component 340.

[0042] The function of the lifting mechanism 310 in this embodiment is to drive the unloading platform 200 to be lifted and lowered. In this embodiment, the first sliding component 330 and the second sliding component 340 are used to lift and lower multiple unloading platforms 200 on opposite sides to ensure the stability of the unloading platform 200 during the lifting process, while facilitating the control of the lifting and lowering of the unloading platform 200.

[0043] During the implementation of the above-mentioned embodiment, the first sliding assembly 330 of the feeding mechanism 20 in this embodiment includes a first connecting plate 331, a first slider 332 and a first limiting member 333.

[0048] During the implementation of the above-mentioned embodiment, the multiple discharge tables 200 of the feeding mechanism 20 in this embodiment are all provided with an export mechanism 210, and the export mechanism 210 includes a transverse pulley 211, a longitudinal pulley 212, a connecting plate 213 and a supporting plate 214, the connecting plate 213 is arranged on the supporting plate 214, the connecting plate 213 is perpendicular to the supporting plate 214, the transverse pulley 211 is arranged on the upper surface of the supporting plate 214, the axis of the transverse pulley 211 is perpendicular to the upper surface of the supporting plate 214, the longitudinal pulley 212 is arranged on the side surface of the supporting plate 214, and the longitudinal pulley 212 is perpendicular to the side surface of the supporting plate 214.

[0049] The unloading table 200 in this embodiment needs to slide in and out back and forth between the material preparation table 30 and the feed. In this embodiment, an export mechanism 210 is provided. The transverse pulley 211 of the export mechanism 210 can reduce the friction force of the side sliding of the unloading table 200, and the longitudinal pulley 212 can reduce the friction force of the bottom sliding of the unloading table 200, so that the sliding is smoother and less stuck. In addition, the connection between the export mechanism 210 and the unloading table 200 is made more stable through the connecting plate 213 and the supporting plate 214.

[0050] During the implementation of the above embodiment, a rotating device 800 is provided on the discharge tray 400 of the feeding mechanism 20 in this embodiment. The rotating device 800 is provided at the bottom of the discharge tray 400 and is also connected to a controller.

[0051] according to Figure 8-Figure 10 As shown, the present application also discloses a wheel hub film laminating machine, which includes Figure 1-Figure 7 The feeding mechanism of the film sticking assembly of any wheel hub film sticking machine comprises a feeding mechanism 20 and a film tearing mechanism 50, wherein the feeding mechanism 20, the film tearing mechanism 50 and the protection mechanism 10 are sequentially arranged along the feeding direction of the wheel hub protection film. The initial automobile wheel hub protection film comprises an adhesive layer and a tearable layer. When in use, the tearable layer needs to be torn off first, and then the adhesive layer is attached to the surface of the wheel hub to complete the film sticking. The feeding mechanism 20 is used for feeding the initial automobile wheel hub protection film and transferring the initial automobile wheel hub protection film to the film tearing mechanism 50.

[0052] The film tearing mechanism 50 includes a film suction component 500, a detection component 600 and a film tearing component 700. The detection component 600 in this embodiment is used to detect the placement position of the wheel hub protective film. When the protective film is placed in the discharge tray 400, the position will be incorrectly offset. When the position is incorrect, the position of subsequent film sticking work will be offset. The position detector can detect the size of the position offset of the wheel hub protective film and transmit it to the controller through the signal transmission unit. After the controller receives the offset information, it is transmitted to the rotating device 800. The rotating device 800 drives the protective film on the discharge tray 400 to rotate, so that the center seam of the wheel hub protective film coincides with the preset position, so that the relative position of the film suction component 500 and the wheel hub protective film is the relative position of normal operation. By setting this detection device in this embodiment, the accuracy of feeding can be improved and the waste of raw materials can be reduced.

[0053] The initial automobile wheel hub protective film includes an adhesive layer and a tearable layer. When in use, the tearable layer needs to be torn off first, and then the adhesive layer is attached to the surface of the wheel hub to complete the film application. The feeding mechanism 60 is used to feed the initial automobile wheel hub protective film and transfer the initial automobile wheel hub protective film to the film tearing mechanism 50.

[0054] The film tearing mechanism 50 includes a film suction component 600, a detection component 700, a film tearing component 800 and a rotating device 900. The detection component 700 in this embodiment is used to detect the placement position of the wheel hub protective film. When the protective film is placed in the feeding mechanism 60, there will be a positional misalignment. When an incorrect position occurs, the position of subsequent film-sticking work will be offset. The position detector can detect the size of the position offset of the wheel hub protective film and transmit it to the controller through a signal transmission unit. After the controller receives the offset information, it is transmitted to the rotating device 900. The rotating device 900 drives the protective film on the feeding mechanism 60 to rotate, so that the center seam of the wheel hub protective film coincides with the preset position, so that the relative position of the film suction component 600 and the wheel hub protective film is a normal relative position. By setting this detection device in this embodiment, the accuracy of feeding can be improved and the waste of raw materials can be reduced.

[0055] The film tearing assembly 800 includes a film cutting knife 810, two clamping jaws 820, and a first driving device 830. The film cutting knife 810 is arranged above the middle of the two clamping jaws 820. The film cutting knife 810 is configured to be able to rise and fall in the vertical direction, and is driven by the first driving device 830 and rotates around an axis arranged along the vertical direction. Exemplarily, in the disclosed embodiment, the wheel hub protective film is circular in shape matching the automobile wheel hub, including a film coated with an adhesive and a release paper adhered to one side with the adhesive, wherein the release paper is in two opposing semicircles and has a gap in the radial direction of the wheel hub protective film for tearing and separating. When the film tearing mechanism 50 of the wheel hub film laminating machine provided in the embodiment of the present disclosure is working, when the wheel hub protective film is taken out from the tray and moved to the specified separation position by the film suction device, the two clamping jaws 820 are controlled to move toward each other, the film separating knife 810 is aligned with the gap between the two pieces of release paper, the film separating knife 810 is controlled to descend and abut against the wheel hub protective film, and the middle part of the wheel hub protective film is pressed downward in the radial direction of the wheel hub protective film, so that the wheel hub protective film is deformed into a "V" shape as a whole in the horizontal direction, and then the film separating knife is driven by the first driving device 830 to rotate around the axis arranged in the vertical direction, so that the wheel hub protective film abutting against the film separating knife 810 is deformed again, so that the edges of the two pieces of release paper are separated from the film coated with the adhesive, and at this time, the release paper can be easily separated from the wheel hub protective film by tearing the edges where the release paper is separated from the film. The structure is simple and easy to implement, which further improves the wheel hub film laminating quality and film laminating efficiency of automobile wheels.

[0056] Depend on Figure 11-Figure 15As shown, the present application also provides another specific embodiment, in which the film scraping blade 810 includes a first film scraping part 200, a second film scraping part 210 and a connecting member 230. The connecting member 230 can be a connecting rod, one end of the connecting rod is connected to the first film scraping part 200, and the other end of the connecting rod 230 is connected to the second film scraping part 210. The bottom of the first film scraping part 200 abuts against one end of the center line of the hub protection film 300, and the second film scraping part 210 abuts against the other end of the center line of the hub protection film 300. The hub protection film 300 includes an adhesive layer 310 and a tearable layer 320. The adhesive layer 310 is a circular protective film, and the tearable layer 320 includes two opposing semicircles, and the opposing part is parallel to the center line of the adhesive layer 310 and on the same vertical plane.

[0057] The inventors have found that the contact area between the existing film-splitting knife 810 and the wheel hub protective film 300 is too large, and the wheel hub protective film is easily damaged during the rotation process. The film-splitting knife 810 in this embodiment only needs the bottom of the first film-scraping part 200 and the bottom of the second film-scraping part 210 to contact the wheel hub protective film 300. By rotating and pressing the first film-scraping part 200 and the second film-scraping part 210, the semicircular end of the tearable layer 320 of the wheel hub protective film 300 can also be lifted up to allow the film-tearing mechanism 50 to tear the film. The film-splitting knife 810 in this embodiment does not need the connecting piece 230 to move in contact with the wheel hub protective film 300, so that the contact area between the film-scraping knife and the wheel hub protective film 300 becomes smaller, reducing the movement trajectory on the wheel hub protective film 300, and protecting the wheel hub protective film 300.

[0058] In the above scheme, the first film scraping part 200 in this embodiment can also be in the shape of an elliptical cylinder, and the first film scraping part 200 includes two first elliptical end faces arranged oppositely, the connecting member 230 connects one of the first elliptical end faces, and the connecting member 230 is connected to the position of the first elliptical end face close to the focus of the hub film. The second film scraping part 210 can also be in the shape of an elliptical cylinder, and the second film scraping part 210 includes two second elliptical end faces arranged oppositely, the connecting member 230 connects one of the second elliptical end faces, and the connecting member 230 is connected to the position of the second elliptical end face close to the focus of the hub film.

[0059] In this embodiment, the film-splitting knife 810 is eccentrically connected to the first film-scraping part 200 and the second film-scraping part 210 through the connecting member 230. When the connecting member 230 rotates to drive the first film-scraping part 200 and the second film-scraping part 210 to rotate, the connecting member 230 rotates at a smaller angle, and the first film-scraping part 200 and the second film-scraping part 210 rotate at a larger angle. At the same time, the elliptical first film-scraping part 200 and the second film-scraping part 210 will also press down the wheel hub protective film 300 during the rotation process, so that the adhesive layer 310 and the tearable layer 320 of the wheel hub protective film 300 are separated. Compared with the existing film-splitting knife 810, the film-splitting knife 810 in this embodiment allows the connecting member 230 to rotate at a smaller angle when the first film-scraping part 200 and the second film-scraping part 210 sweep the same length of path on the wheel hub film, so that the failure rate of the connecting member 230 is lower after long-term use, and the overall space occupied by the film-scraping assembly is smaller. In other words, when the hub film body and the release paper need to be separated by the same area (the area separated by the two is proportional to the size of the path swept by the first scraping film part 200 and the second scraping film part 210 on the hub film), compared with the solution in which the first scraping film part 200 and the second scraping film part 210 are cylindrical and the rotation axis is located at the center, the connector 230 only needs to rotate a smaller angle to achieve the same effect. This makes the connector 230 have a lower failure rate and less wear after long-term use, and the overall space occupied by the scraping film assembly is smaller.

[0060] The inventors have found that the existing film-splitting knife 810 uses the connection member 230 to drive the first film-scraping part 200 and the second film-scraping part 210 to rotate, but there is a problem that the friction between the first film-scraping part 200 and the second film-scraping part 210 and the hub protection film 300 is too large, which is easy to damage the hub protection film. In the above scheme, the film-splitting knife in this embodiment also includes a first motor 240 and a second motor 250, and also includes a first motor and a second motor, the first motor 240 is arranged at one end of the connection member 230 close to the first film-scraping part 200, the first motor 240 is used to drive the first film-scraping part 200 to rotate relative to the connection member 230, the second motor 250 is arranged at one end of the connection member 230 close to the second film-scraping part 210, the second motor 250 is used to drive the second film-scraping part 210 to rotate relative to the connection member 230 when the first motor 240 drives the first film-scraping part 200 to rotate. In this embodiment, the first motor 240 is used to drive the first scraping film part 200 to rotate, and the second motor 250 is used to drive the second scraping film part 210 to rotate. By reducing the medium for force transmission, the rotation efficiency can be improved, and the friction between the first scraping film part 200 and the second scraping film part 210 and the hub protection film 300 can be reduced, thereby protecting the hub protection film.
