[0036] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0037] In addition, when an element in the present invention is referred to as being "fixed to" or "disposed on" another element, it may be directly on the other element or there may be a central element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only and are not intended to be the only embodiment.

[0038] For example, see Figures 1 to 20 A leveling device for PVC color film production includes two stands 1, the two stands 1 are fixed by a crossbeam 101, a leveling bed 2 is fixed on one side of the two stands 1, and a plurality of support columns 201 are fixed on the leveling bed 2 at equal intervals, and also includes: A winding roller 5, which is installed between the two stands 1 through a loading and unloading assembly; The electrostatic guide plate 202 is fixed on the support column 201. A pressing roller 6 is installed on the electrostatic guide plate 202 through a follower component, and a finishing component is also installed on the leveling bed 2. The electrostatic guide plate 202 is used to roll and limit the PVC film body 3 arranged by the finishing component; Two winding assemblies, the two winding assemblies are respectively installed in the two stands 1, and the winding assemblies cooperate with the loading and unloading assemblies and the winding roller 5; Among them, the electrostatic guide plate 202 is made of metal, and the electrostatic guide plate 202 is connected to the outside through a wire; the electrostatic guide plate 202 is connected to the outside through a wire, which means that it is grounded through the wire. The static electricity generated by the PVC film body 3 during the friction process will be transmitted to the ground through the electrostatic guide plate 202 and the wire, thereby making the PVC film body 3 free of static electricity during the friction process.

[0039] In the embodiment of the present invention, the quick loading and unloading of the winding roller 5 is realized by the loading and unloading assembly. After the installation of the winding roller 5 is completed by the loading and unloading assembly, the PVC film body 3 first passes through the electrostatic guide plate 202, and then the leveling bed 2 passes through the finishing assembly to the bottom of the pressure roller 6, and finally fixed to the winding roller 5. The PVC film body 3 is leveled by the finishing assembly. After the finishing, the PVC film body 3 is rolled and limited by the pressure roller 6, so that it will not appear in the first rolling process. When the loading and unloading assembly is working, the winding assembly is also driven to work, and the winding roller 5 is driven to rotate by the winding roller 5. When the winding roller 5 rotates, the PVC film body 3 is wound and the subsequent PVC film body 3 is pulled to be transported on the electrostatic guide plate 202; The above-mentioned movement state enables the PVC film body 3 to be leveled while being rolled up.

[0040] Embodiment 2 is distinguished from Embodiment 1 in that: the finishing assembly comprises a rectifier box 4 fixed to the side of the stand 1 facing the leveling bed 2, the rectifier box 4 is arranged in a V-shape, the side of the PVC membrane body 3 away from the stand 1 is divided into a vertical surface and inclined surfaces located on both sides of the vertical surface, a plurality of air holes 404 are evenly spaced on the inclined surface and the vertical surface, the air holes 404 are arranged in an inclined manner, and the inclined opening angle of the air holes 404 to the rectifier box 4 is 25°; A pump air box 403 is fixed on the cross beam 101 , and the pump air box 403 is connected to an air supply port 405 arranged on the rectifier box 4 through a delivery pipe 402 .

[0041] In the embodiment of the present invention, when the pump air box 403 is working, the air flow is delivered to the rectifier box 4 through the delivery pipe 402 and the air supply port 405, and the air flow is divided by the rectifier box 4 so that the air flow is discharged through the air hole 404. Since the air hole 404 is inclined, the air flow is blown obliquely to the electrostatic guide plate 202. The force of the air flow first acts on the electrostatic guide plate 202 and then disperses under the obstruction of the electrostatic guide plate 202. Please refer to Figure 6 and Figure 7 , the airflow direction line 401 in the figure is the direction of the airflow; The PVC membrane body 3 with larger wrinkles is blown to both sides through the air holes 404 on the vertical surface of the rectifier box 4, and the PVC membrane body 3 blown to both sides is spread on the electrostatic guide plate 202 through the air holes 404 on the inclined surfaces on both sides of the rectifier box 4, so as to complete the flattening process of the PVC membrane body 3; Among them, since the above-mentioned airflow state exists continuously, in conjunction with the conveying of the PVC film body 3 when it is rolled up, the PVC film body 3 is flattened when passing through the rectifier box 4.

[0042] As another embodiment of the present invention, the finishing assembly includes a finishing box 11, the finishing box 11 is fixed on the leveling bed 2, a conveying copper 1101 is fixed on the finishing box 11, a fan 1102 is installed at one end of the conveying copper 1101, and the other end of the conveying copper 1101 is connected to the finishing box 11 toward the side of the stand 1; A diverter plate 1103 is fixed inside the storage box 11, and an exhaust plate 1104 communicating with the interior of the storage box 11 is provided at the rear of the storage box 11; The diverter plate 1103 is arranged in a cone shape, and the connection point between the conveying copper 1101 and the sorting box 11 is located at the tip of the diverter plate 1103; An arc-shaped portion 1105 is provided on a side of the storage box 11 away from the stand 1 .

[0043] In the embodiment of the present invention, the fan 1102 is driven by a motor. When the motor is working, the fan 1102 is driven to rotate. When the fan 1102 rotates, the copper 1101 is conveyed toward the storage box 11. After the airflow enters the storage box 11, it is directly blown to the tip of the diverter plate 1103. The airflow is divided by the diverter plate 1103, so that the airflow is diverted toward both sides. The arc portion 1105 serves to gradually reduce / increase the distance between the storage box 11 and the flat bed 2 and the electrostatic guide plate 202. The smaller the distance between the storage box 11 and the flat bed 2 and the electrostatic guide plate 202, the greater the pressure force of the airflow. Figure 5, the airflow is gradually reduced in the downstream direction. When the PVC film body 3 is transported between the storage box 11 and the electrostatic guide plate 202, the PVC film body 3 on the side where the air supply port 405 is away from the stand 1 is initially spread out by the airflow. As the PVC film body 3 moves toward the storage box 11, the wind force it is subjected to gradually increases, and the PVC film body 3 is spread onto the electrostatic guide plate 202 by the diverted airflow; The difference between this embodiment and the previous embodiment is that the previous embodiment is an open airflow arrangement, which may affect the surrounding environment, while this embodiment is a closed airflow arrangement, and the airflow is discharged toward the bottom of the stand 1 and the exhaust plate 1104 set at the rear of the storage box 11, which has little impact on the surrounding environment; The advantage of the previous embodiment is that the airflow direction is stable and the sorting effect is outstanding.

[0044] Embodiment 3 is distinguished from Embodiment 1 and / or Embodiment 2 in that: the loading and unloading assembly comprises a movable groove 8 provided on opposite sides of two stands 1, a lifting plate 809 is slidably mounted in the movable groove 8, and the lifting plate 809 is connected to the lifting assembly mounted on the stands 1; A pressing plate 8010 is fixed on opposite sides of the two lifting plates 809, and a limiting roller 7 is rotatably installed between the two pressing plates 8010, and the follower assembly cooperates with the pressing plate 8010; The top of the lifting plate 809 is provided with a first arc groove 8015, and the top of the movable groove 8 is provided with a second arc groove 8016 that matches the first arc groove 8015. An entry and exit piece is arranged on the side of the movable groove 8 away from the leveling bed 2 .

[0045] In the embodiment of the present invention, the winding roller 5 is fed into the movable groove 8 through the entry and exit member. When the lifting plate 809 is at the lowest position, the winding roller 5 is fed into the movable groove 8 through the entry and exit member, and the rotating shaft of the winding roller 5 is on the No. 1 arc groove 8015 of the lifting plate 809. Subsequently, the two lifting plates 809 are driven to rise synchronously by the lifting assembly, and the winding roller 5 is driven to rise with the rise of the lifting plate 809. When the No. 1 arc groove 8015 rises to the end of the stroke, the winding roller 5 is limited by the cooperation of the No. 2 arc groove 8016 and the No. 1 arc groove 8015, and at this time, it cooperates with the winding assembly to drive the winding roller 5 to rotate through the winding assembly; After the winding roller 5 completes the winding work, the lifting plate 809 and the winding roller 5 are driven to descend by the lifting assembly, and the follower assembly is driven to work during the descent process, and the rolling limit of the limit roller 7 on the PVC film body 3 is released by the follower assembly, and then the winding roller 5 that has completed the winding is taken out and replaced with another winding roller 5 through the in-and-out piece; Among them, when the lifting plate 809 is raised or lowered, it also drives the pressure plate 8010 and the following movement, and limits the PVC film body 3 through the limiting roller 7. When the PVC film body 3 is rolled up by the winding roller 5, the diameter will gradually increase with the number of winding turns, which will cause the angle between the PVC film body 3 and the winding roller 5 to gradually change and interfere with other components. After being limited by the limiting roller 7, the angle is fixed to eliminate this problem. Secondly, the limiting roller 7 and the pressure plate 8010 make the operation of the PVC film body 3 when passing through the limiting roller 7 simpler.

[0046] The inlet and outlet member includes a release groove 802 formed on the stand 1 and connected to the movable groove 8, and a positioning groove 803 is formed at one end of the release groove 802 away from the movable groove 8; When the lifting plate 809 is at the lowest position, the top is parallel to the bottom of the removal groove 802.

[0047] In the embodiment of the present invention, when the winding roller 5 is disassembled, it is achieved by lifting and lowering the lifting plate 809; When the winding roller 5 is to be unloaded, the lifting plate 809 is lowered to the end of the stroke, at which time the top of the lifting plate 809 is parallel to the bottom of the release groove 802, and the winding roller 5 can be driven into the release groove 802 by external force, and the winding roller 5 is driven to move in the direction away from the movable groove 8 to drive the winding roller 5 away from the movable groove 8 and the release groove 802. Similarly, during installation, the winding roller 5 is guided to move the winding roller 5 into the first arc groove 8015 of the lifting plate 809, and then the lifting plate 809 is raised to the highest point to complete the installation work; Among them, the function of the positioning groove 803 is that since the weight of the winding roller 5 that has completed winding is relatively large, its inertia during movement is also relatively large. In order to prevent the winding roller 5 from rolling down suddenly, the positioning groove 803 can stop the winding roller 5 when it is about to drive out of the release groove 802, giving the operator time to react and avoiding accidents.

[0048] The lifting assembly includes a mounting groove arranged in the stand 1, in which a screw rod 8012 is rotatably mounted, and a threaded sleeve 8013 threadably matched with the screw rod 8012 is sleeved on the screw rod 8012; The movable groove 8 and the installation groove are connected through the groove 801, and the threaded sleeve 8013 and the lifting plate 809 are fixed through a connecting plate, and the connecting plate is in the groove 801; A transmission rod 806 is rotatably installed between the two seats 1, and the transmission rod 806 is connected to two screw rods 8012 through two bevel gear sets 8011 respectively. An assembly groove is also opened on one of the seats 1, and a motor No. 1 808 is fixed in the assembly groove. The output shaft of the motor No. 1 808 is connected to the transmission rod 806 through a transmission chain 807.

[0049] In the embodiment of the present invention, when the No. 1 motor 808 is working, its output shaft drives the transmission rod 806 to rotate through the transmission chain 807, and when the transmission rod 806 rotates, the two screw rods 8012 are driven to rotate synchronously through the bevel gear set 8011; When the screw rod 8012 rotates, the screw sleeve 8013 is driven to rise / fall by cooperating with the screw thread of the screw sleeve 8013. When the screw sleeve 8013 rises or falls, the lifting plate 809 is driven to rise / fall by the connecting plate, thereby realizing the synchronous lifting of the two lifting plates 809. Among them, the lifting and lowering method through threaded transmission has the advantage of labor-saving transmission, and the lifting plate 809 can be limited when it rises to the highest point, because the lifting plate 809 needs to be limited when it is at the highest point and will not fall due to the weight of the winding roller 5.

[0050] The follower assembly includes two slide plates 10 that penetrate the cross beam 101 and slide with it, and springs 1001 are sleeved on the two slide plates 10; A follower plate 804 is slidably mounted on one side of each of the two stands 1. The follower plate 804 is connected to the slide plate 10 via a pull rope 805. At least one guide roller 1002 for limiting the pull rope 805 is rotatably mounted on the stand 1. The pressure roller 6 is rotatably mounted between the two slide plates 10 .

[0051] In the embodiment of the present invention, when the lifting plate 809 descends, it abuts against the follower plate 804 through the pressing plate 8010 after descending a certain distance, and then the lifting plate 809 and the pressing plate 8010 continue to descend, driving the follower plate 804 to follow the descent. When the follower plate 804 descends, the pull rope 805 pulls the slide plate 10 up, so that the slide plate 10 is lifted up and the pressure roller 6 is lifted up, so as to release the rolling limit of the PVC film body 3; When the slide plate 10 rises, the spring 1001 is pulled up, so that the spring 1001 stores elastic potential energy. When the pressing plate 8010 and the lifting plate 809 rise, the slide plate 10 and the pressing roller 6 are driven to descend by releasing the elastic potential energy of the spring 1001 and the gravity of the pressing roller 6 and the slide plate 10. When the slide plate 10 descends, the follower plate 804 is pulled up and reset by the pull rope 805. Secondly, the elastic potential energy of the spring 1001 drives the slide plate 10 and the pressure roller 6 to exert a downward force, thereby giving the pressure roller 6 a rolling downward force.

[0052] The winding assembly includes a motor mounting groove formed on the stand 1, a partition plate 102 is fixed in the motor mounting groove, and the motor mounting groove is divided into a motor cavity and a gear cavity by the partition plate 102; A No. 2 motor 9 is fixed in the motor cavity, a transmission shaft 904 is rotatably installed in the gear cavity, a No. 3 gear 902 is coaxially fixed on the transmission shaft 904, the No. 3 gear 902 is meshed with the No. 2 gear 901 coaxially fixed on the output shaft of the No. 2 motor 9, a No. 4 gear 903 is also coaxially fixed on the transmission shaft 904, the No. 4 gear 903 is outside the motor mounting groove, a No. 1 gear 8014 is coaxially fixed on the winding roller 5, the No. 1 gear 8014 cooperates with the No. 4 gear 903.

[0053] In the embodiment of the present invention, when the No. 2 motor 9 is working, the No. 2 gear 901 rotates through its output shaft, and when the No. 2 gear 901 rotates, the No. 3 gear 902 and the transmission shaft 904 rotate, and when the transmission shaft 904 rotates, the No. 4 gear 903 rotates; When the winding roller 5 rises to the end of the stroke, that is, the highest point, the first gear 8014 meshes with the fourth gear 903, so that the first gear 8014 and the winding roller 5 are driven to rotate when the fourth gear 903 rotates.

[0054] The present invention also provides a flattening device and a flattening method for PVC color film production. The flattening device for PVC color film production is used, and the following steps are included: Step 1: accurately load and unload the winding roller 5 by disassembling the assembly, and drive the winding roller 5 to rotate by the winding assembly; Step 2: leveling the PVC film body 3 wound by the winding roller 5 by means of a finishing component; Step three, the PVC film body 3 that has been leveled is rolled and limited by a pressure roller 6 so that no wrinkles will occur when it is rolled onto a winding roller 5 .
