And a second conveying mechanism 2 for guiding the profile which is subjected to film sticking and has cut the protective film to move is arranged at the downstream of the film cutting mechanism 3. In the present application, the first conveyor 1 and the second conveyor 2 have substantially the same structure, except that they are arranged at different positions on the worktable 6, and the specific functions of the profile in the whole film coating process are different. When the section bar is just put into the first conveying mechanism 1, the first conveying mechanism 1 is responsible for conveying the section bar into the film coating mechanism 4, the film cutting mechanism 3 and the second conveying mechanism 2, when the section bar completely leaves the first conveying mechanism 1, the first conveying mechanism 1 has no conveying effect on the section bar, and the section bar is continuously processed on equipment through displacement and then is finished by the second conveying mechanism 2. In the course of processing, if the length of the profile is long, the profile spans the first conveying mechanism 1 and the second conveying mechanism 2, and at this time, the first conveying mechanism 1 and the second conveying mechanism 2 jointly convey the profile. Specifically, the specific structures of the first conveying mechanism 1 and the second conveying mechanism 2 are two in the present application.

The actuating member 315 is a U-shaped frame, and includes push rods symmetrically disposed on the cutting device 32 and a strip-shaped plate connected to one end of the push rods. Here, the push rod serves to push the pusher back to the starting position, and the strip-shaped plate pushes the cutting device back to the original position.

The film cutting mechanism 3 includes a cutting device 32 provided on the table 6, and when the second conveying mechanism 2 guides the profile to be displaced, the cutting device 32 is displaced at the same speed as the profile and cuts the protective film during the displacement. Specifically, the cutting device 32 includes a mounting plate 321 slidably fitted over the stage 6 and having an actuator 315, and a first cylinder 322 provided on the mounting plate 321 and configured to cut the protective film by driving a cutter 323 in a telescopic manner. In this embodiment, the worktable 6 is provided with a mounting plate 324. The bottom of the mounting base plate 324 is fixedly provided with a first bearing seat 317 for bearing the rotating member 312, and the rotating member 312 is rotatably connected with the first bearing seat 317. In addition, an adjusting component 33 for adjusting the tightness degree of the synchronous belt 313 is arranged on the workbench 6.

When the tightness of the two timing belts 313 needs to be adjusted, the front-back adjustment of the screwing adjusting screw 336 can drive the second bearing seat 333 to slide back and forth along the guide rail, so that the tightness of the two timing belts 313 can be adjusted. In addition, the upper surface of the mounting base plate 324 is provided with a first slide rail 325. The first slide 325 cooperates with a first slide 326 fixed to the mounting plate 321 to allow the mounting plate 321 to slide on the mounting base 324.

The specific implementation mode is as follows: the second cylinder 316 is provided below the table 6, i.e., on a surface opposite to the conveying mechanism or the like. After the film cutting process is completed, the strip-shaped rod of the actuating piece 315 is pushed by the pushing piece 314 to the output end of the second cylinder 316, and at this time, the second cylinder 316 is in a contracted state. The control center operates the second cylinder 316 to extend, pushing the actuator 315 back to the starting position, and the cutting device 32 is also pushed to the starting position to perform the cutting of the lower wheel. The method is repeated, and the processing continuity and the working efficiency of the device are greatly improved.

A film pressing mechanism 5 for further smoothing and pressing the protective film is arranged between the film cutting mechanism 3 and the second conveying mechanism 2. In this embodiment, the film pressing mechanism 5 comprises a mounting frame 501, a mounting rod 502 and a pressing wheel 503, the mounting frame 501 is fixedly connected to the workbench 6, the mounting rod 502 is connected to the mounting frame 501 and points to the profile, and the pressing wheel 503 is rotatably connected to one end, facing the profile, of the mounting rod 502. The installation rod 502 and the pinch rollers 503 are provided in plurality, and the position of the installation rod 502 on the installation frame 501 is adjusted in a bolt fixing mode, so that the pinch rollers 503 correspond to four surfaces of the section bar. Through adopting above-mentioned technical scheme, when the section bar gos forward to hold-down mechanism, the surface that protection film and section bar contact is through the surface of pinch roller 503, is applyed pressure to both by pinch roller 503 and pastes tightly, and the another side of section bar is through pinch roller 503 simultaneously, and pinch roller 503 applys the power of horizontal direction to the section bar simultaneously, improves the laminating degree of film and section bar, reaches better pad pasting effect.

The working principle of the embodiment is as follows: when the film is attached, a worker places a first section bar on the bearing roller, the first section bar is transported to the position of the fourth sensor 114 by the first conveying mechanism 1, when the first section bar completely passes over the fourth sensor 114, the second driving motor 201 is switched to a low-speed operation mode, and buffer preparation is made for positioning the first section bar at the fourth sensor 114. In the above operation, the clutch 311 is always in the disengaged state, and the power of the second driving motor 201 is not transmitted to the timing belt 313. The profile passes through the fourth sensor 114 in a low-speed state, under the control of the control center, a certain distance is kept between the tail end of the first profile and the fourth sensor 114, meanwhile, the position of the tail end of the first profile also corresponds to the position of the pushing piece 314 on the synchronous belt 313, at this time, the second driving motor 201 stops running, and the film covering mechanism 4 finishes film covering on the peripheral surface of the first profile in the previous running process of the first profile. The protective film on the first profile is still in a state of being connected with the film roll and is not broken. A worker puts a second section bar into the first conveying mechanism 1, the first conveying mechanism 1 conveys the second section bar to the position of the fourth sensor 114, according to a preset program of the control center, the first conveying mechanism 1 controls one end of the second section bar to move across the fourth sensor 114, and the tail end of the first section bar and the head end of the second section bar are kept at a certain distance, so that subsequent cutting is facilitated. After the distance is confirmed, both the profiles are kept in a stopped state, and in the above process, the second driving motor 201 is always kept in a stopped state. And according to a preset program of the control center, the step of cutting the protective film can be carried out after the distance is confirmed. At this time, the clutch 311 is engaged with the second drive motor 201, and the first drive motor 101 and the second drive motor 201 are started at the same speed. Since the clutch 311 and the second driving motor 201 have completed the engagement, the clutch 311 transmits power to the timing belt 313, so that the pushing member 314 on the timing belt 313 advances at the same speed as the end of the first profile. When the end of the first profile reaches the knife edge position of the knife 323, the pusher 314 has also simultaneously come into abutment with the cutting device 32. When the end of the first profile passes the knife edge position of the knife 323, the cutting device 32, under the urging of the pusher 314, leaves the sixth sensor 116 at the same speed as the end of the first profile. The sixth sensor 116 feeds back a signal to the first cylinder 322, which cylinder 322 extends the cutter 323 at a very fast speed, thereby cutting the protective film around the profile. Since the traveling speed of the first cylinder 322 is consistent with that of the first section bar, the condition of knife collision does not occur in the cutting process. Because the sensor is also arranged on the first air cylinder 322, when the first air cylinder 322 finishes cutting, a signal is fed back to the clutch 311 immediately, the clutch 311 is disconnected from power transmission with the second driving motor 201, at the moment, the second driving motor 201 continues to operate, the first section bar with the cut-off protective film after film pasting is finished is transported out, the cutting device 32 stops moving forwards due to lack of a power source, and the second air cylinder 316 pushes the cutting device 32 to the initial position to cut the protective film of the second section bar. The second section bar is identical to the first section bar in operation process, and the third section bar is put in to repeat the operation process. The film laminating and cutting are carried out repeatedly and uninterruptedly, the continuity of the working procedures is kept, and the working efficiency of film sticking is greatly improved.

While the preferred embodiments of the present invention have been illustrated and described, it will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the utility model as defined by the appended claims.
