DETAILED DESCRIPTION

[0020] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0021] When the existing flattening device for processing reflective film uses flattening rollers to flatten the reflective film, the flattening effect may be poor due to the excessively large or small distance between the flattening rollers when facing reflective films with different hardnesses.

[0022] Therefore, the present application provides a flattening device for processing reflective film, which comprises a lower flattening roller, an upper flattening roller and a second recess. When flattening reflective films with different hardnesses, the position of the lower flattening roller can be manually adjusted. If the material of the reflective film is relatively hard, the distance between the lower flattening rollers is increased, and vice versa. After the lower flattening rollers are adjusted, the distance between the lower flattening rollers is adjusted by the second recess, and the upper flattening roller is fixed by a fixing device to avoid movement when the upper flattening roller contacts the reflective film. In this way, reflective films with different hardnesses can be flattened.

[0023] The components in the present application are sequentially connected by those skilled in the art, and the specific connection and operation sequence should be referred to the following working principle. The detailed connection means is a known technology in the art, and the following mainly introduces the working principle and process.

[0024] Embodiment one: by Figures 1-5It can be known that a kind of reflective film processing and handling flattening device, including workbench 1, the top of workbench 1 is fixedly connected with multiple heating plates 11, the front of workbench 1 is equipped with controller 12, reflective film processing and handling flattening device further includes adjusting device 2, lifting device 3 and driving device 4, adjusting device 2 is set to the top of workbench 1;Lifting device 3 is set to the outside of adjusting device 2;Driving device 4 is set to two, respectively set to the top of workbench 1 two sides, and located at the two sides of adjusting device 2;Wherein, different hardness reflective film is flattened by adjusting device 2, lifting device 3 controls the flattening of different thickness reflective film, and unwinding and winding of reflective film are completed by driving device 4;

[0025] In the specific implementation process, it is worth pointing out that, by adjusting device 2, different hardness reflective film can be standardized flattening work, by lifting device 3, different thickness reflective film is adapted, to avoid causing excessive pressure on reflective film, by driving device 4, unwinding and winding of reflective film are realized, wherein heating plate 11 is preheated between flattening work, and staff uses temperature measuring tool to monitor that appropriate temperature condition is reached, then flattening work is carried out, so that it is easier to shape in flattening process, improve flattening effect, and the model of controller 12 is CP1E-N40DR-A;

[0026] Further, adjusting device 2 includes first groove 21, first mounting plate 22, lower flattening roller 23, mounting bracket 24, second groove 25, limiting piece 26, upper flattening roller 27 and fixing device 28, multiple first grooves 21 are set, and are respectively opened in the top of workbench 1 front and back;First mounting plate 22 is inserted in the inner wall of first groove 21, and is attached to the top of workbench 1;Lower flattening roller 23 is rotatably connected between the two first mounting plates 22 in front and back through sealing bearing;Mounting bracket 24 is set to two, and is respectively set to the top of workbench 1, and is set front and back;Multiple second grooves 25 are set, and are respectively opened in the top of mounting bracket 24;Limiting piece 26 is inserted in the inner wall of second groove 25;Upper flattening roller 27 is rotatably connected between the two limiting pieces 26 in front and back through sealing bearing;Fixing device 28 is set to the top of mounting bracket 24;Wherein, the spacing between lower flattening roller 23 is adjusted by the first groove 21 and the first mounting plate 22 insertion relationship, the spacing between upper flattening roller 27 is adjusted by mounting bracket 24, second groove 25 and limiting piece 26, and limiting piece 26 is fixed by fixing device 28;

[0027] In the specific implementation process, it is particularly worth pointing out that when facing the flattening work of the reflection film with different hardness, the personnel can manually adjust the position of the lower flattening roller 23, and the top of the workbench 1 is provided with a plurality of first grooves 21 for placing the first mounting plate 22. If the material of the reflection film is relatively hard, the distance between the lower flattening rollers 23 is increased, and vice versa. After adjusting the lower flattening roller 23, the upper flattening roller 27 can also be adjusted according to the distance between the lower flattening rollers 23 through the second groove 25. After adjusting the upper flattening roller 27, the upper flattening roller 27 is fixed through the fixing device 28 to avoid the movement of the upper flattening roller 27 when it contacts the reflection film. In this way, the reflection film with different hardness can be flattened, avoiding the situation that the flattening effect of the soft reflection film is not ideal due to the too large distance between the flattening rollers, or the hard reflection film is damaged due to extrusion because the distance between the flattening rollers is too small. The limiting piece 26 is provided with the same shape as the second groove 25 on the side close to the second groove 25, which can be inserted into the inner wall of the second groove 25, and the other end is rotatably connected with the upper flattening roller 27 through a sealing bearing, so that the upper flattening roller 27 can rotate. The upper flattening roller 27 and the lower flattening roller 23 are staggered, which can make the reflection film receive forces in different directions and angles when passing through the upper and lower flattening rollers, which helps to better eliminate wrinkles and stress on the film material and improve the flattening quality. When the upper flattening roller 27 approaches the lower flattening roller 23, the mounting bracket 24 and the first mounting plate 22 are in a staggered shape, which ensures that the upper flattening roller 27 does not affect the approach to the lower flattening roller 23.

[0028] Further, the fixing device 28 comprises a horizontal plate 281, a pressure sensor 282, a fixing plate 283 and a fixing bolt 284. The horizontal plate 281 is arranged above the mounting bracket 24. The pressure sensor 282 is fixedly connected to the bottom of the horizontal plate 281. The fixing plate 283 is fixedly connected to the bottom of the pressure sensor 282 and corresponds to the second groove 25. The fixing bolt 284 is rotatably connected to the inner wall of the horizontal plate 281 through a sealing bearing. The fixing plate 283 fixes the limiting piece 26 in the inner wall of the second groove 25. The pressure sensor 282 monitors the pressure of the upper flattening roller 27 on the reflection film. The horizontal plate 281 and the mounting bracket 24 are fixed through the fixing bolt 284.

[0029] In the specific implementation process, it is worth pointing out that when the adjustment of the upper flattening roller 27 is completed, the fixed plate 283 is inserted into the inner wall of the second groove 25, the bottom of the fixed plate 283 is just attached to the top of the limiting part 26, then the fixed bolt 284 is fixed to the inner wall of the mounting frame 24, the fixation between the horizontal plate 281 and the mounting frame 24 is realized, and through the action of the pressure sensor 282, when the upper flattening roller 27 approaches the reflective film until it is attached to the top of the reflective film, the pressure sensor 282 monitors the pressure between the upper flattening roller 27 and the reflective film, and more reasonable flattening work is realized for reflective films of different thicknesses. In order to avoid the instability of the value of the pressure sensor 282 when monitoring the pressure due to the excessive length of the horizontal plate 281, multiple fixed bolts 284 can be provided to ensure the accuracy of the monitoring of the pressure sensor 282. The model of the pressure sensor 282 is TPSADA;

[0030] Further, the lifting device 3 includes an electric sliding rail 31 and an electric sliding block 32.

Through the electric sliding rail 31 and the electric sliding block 32, the upper flattening roller 27 approaches the reflective film.

[0031] In the specific implementation process, it is worth pointing out that the model of the electric sliding rail 31 and the electric sliding block 32 is RXP45. During the flattening work, first, the lower flattening roller 23 and the upper flattening roller 27 are adjusted according to the hardness and material of the reflective film, then the controller 12 controls the movement of the electric sliding block 32 on the electric sliding rail 31, the mounting frame 24 drives the upper flattening roller 27 to approach the reflective film, until the upper flattening roller 27 is attached to the top of the reflective film, and the pressure between the upper flattening roller 27 and the reflective film at this time is monitored by the pressure sensor 282. The controller 12 controls the movement of the electric sliding block 32 by transmitting the monitored information to the controller 12, and realizes the standard flattening work for reflective films of different thicknesses. When the electric sliding rail 31 and the controller 12 are connected, first, the electric sliding rail 31 and the controller 12 are connected to a suitable power supply, then the control signal connection is performed. The output point of the controller 12 can output an on-off signal or an analog signal, so as to control the speed of the electric sliding rail 31. If the electric sliding rail 31 adopts on-off control, the output point of the PLC is connected to the control input end of the electric sliding rail 31. If analog control is adopted, an analog voltage or current signal is output by the analog output module of the PLC, and then connected to the analog input interface of the electric sliding rail 31.

[0032] Specifically, when the flatting device is used to process the reflective film with different hardness, the user can manually adjust the position of the lower flattening roller 23, the top of the workbench 1 is provided with a plurality of first grooves 21 for placing the first mounting plate 22, if the material of the reflective film is hard, the distance between the lower flattening rollers 23 is increased, and vice versa.

After adjusting the upper flattening roller 27, the fixed plate 283 is inserted into the inner wall of the second groove 25, so that the bottom of the fixed plate 283 is in close contact with the top of the limiting piece 26, and then the fixed bolt 284 is fixed on the inner wall of the mounting frame 24 to fix the horizontal plate 281 and the mounting frame 24. Through the action of the pressure sensor 282, when the upper flattening roller 27 approaches the reflective film until the top of the reflective film is in close contact, the pressure sensor 282 monitors the pressure between the upper flattening roller 27 and the reflective film, so that the reflective film with different thickness can be flattened more reasonably. First, adjust the lower flattening roller 23 and the upper flattening roller 27 according to the hardness and material of the reflective film, then control the electric sliding block 32 to move on the electric sliding rail 31, drive the upper flattening roller 27 to approach the reflective film through the mounting frame 24 until the upper flattening roller 27 is in close contact with the top of the reflective film, and monitor the pressure between the upper flattening roller 27 and the reflective film at this time through the pressure sensor 282. The pressure sensor 282 transmits the monitored information to the controller 12, and the controller 12 controls the movement of the electric sliding block 32 to realize the standard flattening work of the reflective film with different thickness.
