[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] 1.

[0018] 3.

When the processing base belt deviates to the other side during the movement, the controller controls the other first hydraulic cylinder to work, so that the processing base belt performs corresponding correction operations according to the different offset directions.

[0019] 4. The connecting hole on the surface of the connecting rod rises synchronously and connects with the inside of the L-shaped tube, so that the corresponding drainage pump discharges the slurry in the liquid storage box along the L-shaped tube, and applies it to the top surface of the offset side of the processing base belt through the second scraper, so as to prevent the offset part of the processing base belt from being unable to be coated with slurry, and reduce the influence of the processing base belt offset on the processing of the green film. After the processing base belt is corrected, the corresponding U-shaped rod drives the connecting rod to move downward and re-blocks the L-shaped tube, so as to reduce the waste of slurry. By fixing a retaining ring at the bottom of the L-shaped tube, the connecting hole on the connecting rod and the inside of the L-shaped tube are partially connected, and the part below the connecting hole is slidably sealed by the retaining ring, so as to prevent the slurry from overflowing from below the connecting hole.

[0033] The following description is used to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments described below are only examples, and those skilled in the art may think of other obvious variations.

[0034] like Figures 1 to 12 The automatic deviation correction device of a film casting machine shown in the figure comprises a mounting shell 1, both ends of the bottom of the mounting shell 1 are fixedly connected to brackets 2, one end of the two brackets 2 away from each other is rotatably connected to a first connecting shaft 3, the first connecting shaft 3 is fixedly connected to a mounting roller 4, the brackets 2 are fixedly installed with a first motor 5, and the output shafts of the first motor 5 are respectively fixedly connected to one end of the adjacent first connecting shaft 3;

[0035] A processing base belt 6 is arranged on the top of the installation shell 1, and the two ends of the processing base belt 6 are respectively fixedly wound on the surfaces of two installation rollers 4, and the two ends of the installation shell 1 are rotatably connected with a second connecting shaft 7, and the second connecting shaft 7 is fixedly connected with a matching roller 8, and the matching roller 8 is located on the bottom surface of the processing base belt 6. The installation shell 1 is connected with a slurry coating mechanism and a heating and drying mechanism;

[0036] Two spiral rollers 9 are arranged at both ends of the interior of the installation shell 1, and the threads of the two adjacent spiral rollers 9 are arranged in opposite directions. The interior of the installation shell 1 is connected to an offset detection mechanism, and the spiral rollers 9 are connected to a lifting and rotating mechanism. When the offset detection mechanism detects that the processing base belt 6 deviates to one side, the lifting and rotating mechanism causes the corresponding two spiral rollers 9 with the same thread direction to rise synchronously and rotate in contact with the bottom surface of the processing base belt 6; when working, the prior art usually evenly applies slurry on the surface of the base belt, and uses a redirecting roller to extrude one side of the deviated base belt back to the right position during the horizontal movement of the base belt to generate deviation. In the actual processing process, since the base belt itself is a deformable material, it is easy to make the base belt deformed by squeezing the side of the base belt. During the movement, the surface of the base belt is squeezed and wrinkled, which causes the raw film coated on the surface of the base belt to crack and break, affecting the processing effect of the raw film. The technical solution can solve the above problems, and the specific working method is as follows: the output shafts of the two first motors 5 drive the adjacent first connecting shafts 3 to rotate, so that the two installation rollers 4 rotate synchronously with the first connecting shafts 3, and the two installation rollers 4 respectively wind up and unwind the processing base belt 6, so that the processing base belt 6 moves to one end. During the movement of the processing base belt 6, the part of the processing base belt 6 located above the installation shell 1 is kept horizontal through the support of the two matching rollers 8, and the matching rollers 8 are used to keep it in a tensioned state. During the movement of the processing base belt 6, the matching rollers 8 are The contact with the bottom surface of the processing base belt 6 drives the second connecting shaft 7 to rotate in coordination. When the processing base belt 6 moves, the slurry of the processing green film is evenly coated on the top surface of the processing base belt 6 through the action of the slurry coating mechanism, and then the green film on the top surface of the processing base belt 6 is dried and solidified through the action of the heating and drying mechanism, and is peeled off and separated from the processing base belt 6 before the processing base belt 6 is rolled up in the direction of the installation roller 4 at one end, so as to extract the green film. When the processing base belt 6 deviates to one side during the movement, the deviation is detected and alarmed by the action of the deviation detection mechanism, and the corresponding two spiral rollers 9 with the same thread direction are synchronously raised and rotated in contact with the bottom surface of the processing base belt 6 through the action of the lifting and rotating mechanism, and the threads on the surface of the spiral rollers 9 When the protrusion rotates in contact with the bottom surface of the processing base belt 6, the rotational guiding effect of the threaded protrusion causes the processing base belt 6 to gradually return from the deviated position during the movement, and after moving to the center position, the offset detection mechanism detects that the offset is cancelled, and the lifting and rotating mechanism releases the contact rotation between the corresponding spiral roller 9 and the bottom surface of the processing base belt 6. The spiral roller 9 and the bottom surface of the processing base belt 6 are in contact and rotated, and the threaded protrusion on the surface of the spiral roller 9 guides the bottom surface of the processing base belt 6 evenly during the rotation, corrects the deviation of the processing base belt 6, reduces the deformation wrinkles generated during the correction process of the processing base belt 6, improves the flatness of the surface of the processing base belt 6, and reduces the probability of cracking and damage of the green film on the surface of the processing base belt 6, thereby ensuring the processing effect of the green film.

[0037] As a further embodiment of the present invention, the slurry coating mechanism includes a liquid storage box 10, which is fixedly installed on the top of the mounting shell 1, and the top of the liquid storage box 10 is fixedly connected to a liquid injection hopper 11, and a liquid outlet 12 is opened at the bottom of one side of the liquid storage box 10. A rectangular frame 13 is fixedly connected to one side of the liquid storage box 10, and the liquid outlet 12 is located on one side of the inside of the rectangular frame 13. A first scraper 14 is fixedly connected to the inside of the rectangular frame 13; when working, the mixed slurry is poured along the liquid injection hopper 11 is poured into the interior of the liquid storage box 10, and during the movement of the processing base belt 6, the slurry flows along the liquid outlet 12 at the lower side of the liquid storage box 10 to the top surface of the processing base belt 6, and the slurry on the top surface of the moving processing base belt 6 is scraped and coated by the first scraper 14, so as to ensure the flatness of the slurry on the top surface of the processing base belt 6, and a rectangular frame 13 is set on one side of the liquid outlet 12 to block both sides of the liquid outlet 12, thereby reducing the overflow of the slurry from both sides of the liquid outlet 12.

[0038] As a further embodiment of the present invention, the heating and drying mechanism includes a drying shell 15, which is fixedly mounted on the top of the mounting shell 1, and a plurality of infrared heating lamps 16 are fixedly mounted in a linear array inside the drying shell 15; during operation, after the first scraper 14 scrapes and applies the slurry on the top surface of the moving processing base belt 6, the processing base belt 6 drives the slurry to continue to move toward the inside of the drying shell 15, and when moving inside the drying shell 15, the slurry on the top surface of the processing base belt 6 is dried and solidified by a plurality of infrared heating lamps 16, which is conducive to the peeling and separation of the fixedly formed green film from the top surface of the processing base belt 6, and is heated by the infrared heating lamps 16, thereby reducing the airflow disturbance during the heating process and improving the surface flatness of the green film during the drying process.

[0039] As a further embodiment of the present invention, the interior of the installation shell 1 is fixedly connected with a plurality of double-pass tubes 17 in a linear array, and the surfaces of the double-pass tubes 17 are rotatably connected with heat-conducting rings 18, which are all located below the drying shell 15 and in contact with the bottom surface of the processing base belt 6. A hot air blower 19 is fixedly installed at the bottom of the installation shell 1, and the air outlet end of the hot air blower 19 is fixedly connected with a multi-connecting tube 20, and the multiple connecting ends of the multi-connecting tube 20 are respectively fixedly connected to one end of the adjacent double-pass tube 17; when working, the hot air is discharged outward through the air outlet end of the hot air blower 19, and the hot air enters the multi-connecting tube 2 along the air outlet end of the hot air blower 19. 0, and then enter the interior of the double-pass tube 17 along the multi-connecting tube 20 to heat the double-pass tube 17. The heat-conducting ring 18 on the surface of the double-pass tube 17 conducts heat contact with the bottom surface of the processing base belt 6 during the movement by means of contact heat conduction, thereby improving the drying efficiency of the green film. In addition, during the movement of the processing base belt 6, the heat-conducting ring 18 cooperates and rotates along the surface of the double-pass tube 17 by means of contact friction, so that the surface of the heat-conducting ring 18 is evenly in contact with the bottom surface of the processing base belt 6 during the rotation, thereby ensuring the stability of the heating temperature. The hot air inside the double-pass tube 17 is continuously discharged along the opening at one end, so that the internal heat maintains the temperature.

[0040] As a further embodiment of the present invention, the offset detection mechanism includes two U-shaped mounting frames 21, which are respectively fixedly connected on both sides of the interior of the mounting shell 1 and are located between the drying shell 15 and the liquid storage box 10. The interior of the U-shaped mounting frames 21 is oppositely arranged and fixedly installed with a laser emitter 22 and a laser receiver 23, and the laser emitter 22 and the laser receiver 23 are respectively located at the upper and lower sides of the adjacent side of the processing base belt 6; when working, by arranging the laser emitter 22 and the laser receiver 23 on both sides of the processing base belt 6, and making the laser emitter 22 and the laser receiver 23 located at the upper and lower sides of the processing base belt 6, the laser signal of the laser emitter 22 is blocked by the processing base belt 6. When the processing base belt 6 deviates to one side during the movement, the laser signal emitted by the laser emitter 22 on the other side loses its blocking effect as the processing base belt 6 deviates, and is received by the laser receiver 23 arranged oppositely. After the laser receiver 23 receives the signal, the controller connected to the laser receiver 23 controls the lifting and rotating mechanism to work.

[0041] As a further embodiment of the present invention, the lifting and rotating mechanism includes four connecting frames 24, which are all arranged inside the mounting shell 1, and the connecting frames 24 are rotatably connected with rotating shafts 25, and the spiral rollers 9 are respectively fixedly connected to the corresponding rotating shafts 25.

The bottom of the mounting shell 1 is fixedly connected with a fixing frame 31. Two first hydraulic cylinders 32 are fixedly installed at the bottom of the fixing frame 31. The piston shafts of the first hydraulic cylinders 32 penetrate the fixing frame 31 and extend to the inside of the fixing frame 31 and are fixedly connected to a U-shaped rod 33. Both ends of the U-shaped rod 33 penetrate the mounting shell 1 and extend to the inside of the mounting shell 1 and are fixedly connected to the bottom of the corresponding connecting frame 24. The spiral rollers 9 above the connecting frame 24 at both ends of the U-shaped rod 33 have the same spiral direction. When working, when the processing base belt 6 deviates to one side during movement, the laser emitter 22 on the other side emits The laser signal is received by the laser receiver 23 which is arranged opposite to it. The controller connected to the laser receiver 23 controls the corresponding first hydraulic cylinder 32 to work. The piston shaft of the first hydraulic cylinder 32 drives the corresponding U-shaped rod 33 to move upward. The two ends of the U-shaped rod 33 move upward along the penetration point, and drive the connecting frames 24 at both ends of the U-shaped rod 33 to move upward along the movable groove 26. The two spiral rollers 9 with the same spiral direction inside the connecting frames 24 at both ends of the U-shaped rod 33 rise synchronously with the connecting frames 24 and contact with the bottom surface of the processing base belt 6. The rotating shaft 25 on the connecting frame 24 rises synchronously with the connecting frame 24, and in the process of rising, the second gear 30 and the first gear 29 at one end of the rotating shaft 25 are rotated.

During the upward movement of the plug-in rod 36, the connecting hole 37 on the surface of the plug-in rod 36 rises synchronously and communicates with the interior of the L-shaped tube 35, so that the corresponding drainage pump 34 discharges the slurry in the liquid storage box 10 along the L-shaped tube 35, and applies it to the top surface of the offset side of the processing base belt 6 through the second scraper 39, so as to prevent the offset part of the processing base belt 6 from being unable to be coated with slurry, and reduce the influence of the offset of the processing base belt 6 on the processing of the green film. After the processing base belt 6 is corrected, the corresponding U-shaped rod 33 drives the plug-in rod 36 to move downward and re-block the L-shaped tube 35, so as to reduce the waste of slurry. By fixing the retaining ring 38 at the bottom of the L-shaped tube 35, the connecting hole 37 on the plug-in rod 36 is partially connected with the interior of the L-shaped tube 35, and the part below the connecting hole 37 is slidably sealed by the retaining ring 38, so as to prevent the slurry from overflowing from below the connecting hole 37.

During the movement of the processing base belt 6, the part of the processing base belt 6 located above the installation shell 1 is kept horizontal by the support of the two matching rollers 8, and the matching rollers 8 are used to keep the tension state. During the movement of the processing base belt 6, the matching rollers 8 drive the second connecting shaft 7 to rotate in coordination through the contact with the bottom surface of the processing base belt 6. When the processing base belt 6 moves, the slurry of the processing green film is evenly coated on the top surface of the processing base belt 6 through the action of the slurry coating mechanism, and then the green film on the top surface of the processing base belt 6 is dried and solidified through the action of the heating and drying mechanism, and is peeled off and separated from the processing base belt 6 before the processing base belt 6 is reeled in the direction of the installation roller 4 at one end, so as to extract the green film. When the center deviates to one side, the deviation is detected and alarmed by the deviation detection mechanism, and the lifting and rotating mechanism makes the corresponding two spiral rollers 9 with the same thread direction rise synchronously and contact and rotate with the bottom surface of the processing base belt 6. When the thread protrusions on the surface of the spiral roller 9 contact and rotate with the bottom surface of the processing base belt 6, the processing base belt 6 gradually returns from the deviated position during the movement through the rotational guiding effect of the thread protrusions. After moving to the center position, the deviation detection mechanism detects that the deviation is cancelled, and the lifting and rotating mechanism releases the contact and rotation of the corresponding spiral roller 9 and the bottom surface of the processing base belt 6. The spiral roller 9 and the bottom surface of the processing base belt 6 contact and rotate, and the thread protrusions on the surface of the spiral roller 9 uniformly guide the bottom surface of the processing base belt 6 during the rotation process, correct the deviation of the processing base belt 6, reduce the deformation wrinkles generated in the correction process of the processing base belt 6, improve the flatness of the surface of the processing base belt 6, and reduce the probability of cracking and damage of the green film on the surface of the processing base belt 6, thereby ensuring the processing effect of the green film.
