DETAILED DESCRIPTION

[0029] Two implementation modes of the present application are described in detail below with reference to the accompanying drawings.

[0030] The first implementation method:

[0031] See also Figure 1-Figure 10 , a temperature-controlled polymer decorative film multilayer co-extrusion production device, comprising a co-extruder 2, a molding machine 3 arranged under the co-extruder 2, a rear shell 6 and a front shell 5 both arranged outside the molding machine 3, a control panel 4 and an intelligent signal processor both installed on the front shell 5;

[0032] The forming machine 3 includes a main winder 37 and a winding drum 363 installed at the end of the main winder 37. The winding drum 363 is made of a material that is easy to split among existing rolls and is used for winding the finished film. A main divider 39 and an auxiliary divider 32 are arranged on the periphery of the main winder 37. The main divider 39 and the auxiliary divider 32 both include a support rod 390, a plurality of horizontal drive motors B395 arranged on the support rod 390, and a dividing knife 394 fixed on the shell of each horizontal drive motor B395. A force sensor 393 is installed at the connection between the shell of each horizontal drive motor B395 and the dividing knife 394. The force sensor 393 is a high-precision force sensor that can judge the sharpness of the dividing knife 394 by the magnitude of the force. The output end of the horizontal driving motor B395 is provided with a shaft gear, and a slideway meshing with the shaft gear is provided in the support rod 390. By installing the horizontal driving motor B395 on the dividing knife 394, the distance between the dividing knives 394 can be automatically adjusted. A replacement motor 391 is installed on one side of the support rod 390, and a replacement rod 392 meshing with the gear at the output end of the replacement motor 391 is provided on the inner side of the rear shell 6. The rear shell 6 is provided with a slideway matching the main divider 39 and the auxiliary divider 32. By setting the interaction between the gear of the replacement motor 391 and the replacement rod 392, the main divider 39 and the auxiliary divider 32 can be moved along the slideway on the rear shell 6.

[0033] In addition, the intelligent signal processor includes a winding module, which is connected to the control panel 4 by signal. The winding module is electrically connected to the replacement motor 391, the force sensor 393 and the horizontal drive motor B395 respectively. The above-mentioned winding module can detect the dividing knife 394 of the main divider 39 through the force sensor 393. When the sharpness of the dividing knife 394 is low, the winding module will drive the corresponding replacement motor 391 to realize the mutual replacement of the main divider 39 and the auxiliary divider 32, and prompt the personnel to maintain the dividing knife 394 of the main divider 39 on the control panel 4; the operator can also set the spacing of the dividing knife 394 on the control panel 4, and the winding module will control the horizontal drive motor B395 according to its numerical value so that the spacing of the dividing knife 394 meets the above-mentioned set value.

[0034] To sum up, when the multi-layer co-extrusion production device is operating normally, the operator can input the corresponding value on the control panel 4 according to the width requirement of the polymer decorative film. The winding module will automatically adjust the spacing of the dividing knife 394 through the horizontal drive motor B395 according to the corresponding value to achieve the cutting of the polymer decorative film. The process will also cut the winding drum 363 to facilitate the subsequent packaging of finished products. As the number of finished film on the main winder 37 increases, the winding module will also control the replacement motor 391 of the main divider 39 to regularly adjust the distance between the main winder 37; when the winding module detects that the dividing knife 394 of the main divider 39 is not sharp enough through the force sensor 393, the winding module will drive the corresponding replacement motor 391 to achieve the mutual replacement of the main divider 39 and the auxiliary divider 32, and prompt the personnel to maintain the dividing knife 394 of the main divider 39 on the control panel 4.

[0035] In addition, the forming machine 3 also includes an auxiliary reel 36 and a cutter 38 arranged between the auxiliary reel 36 and the main reel 37. Telescopic rods are arranged in the main reel 37 and the auxiliary reel 36. The main reel 37 and the auxiliary reel 36 can control the corresponding telescopic rods to extend and retract, and can also control the corresponding telescopic rods to rotate. A winding drum 363 is sleeved on the telescopic rods of the main reel 37 and the auxiliary reel 36. The shell of the auxiliary reel 36 is fixed with a secondary replacement ring 361, and the shell of the main reel 37 is fixed with a main replacement ring 371. The inner ring of the auxiliary replacement ring 361 is provided with teeth meshing with the rotor gear on the output end of the auxiliary replacement motor 362. The auxiliary replacement motor 362 is fixed inside the rear shell 6. The inner ring of the main replacement ring 371 is provided with teeth meshing with the rotor gear on the output end of the main replacement motor 372. The main replacement motor 372 is fixed inside the rear shell 6. The rear shell 6 is provided with a The auxiliary reel 36 and the main reel 37 have matching arc slides, and the winding module is electrically connected to the main reel 37, the auxiliary reel 36, the auxiliary replacement motor 362 and the main replacement motor 372 respectively. The winding module can control the auxiliary reel 36 and the main reel 37 to realize the corresponding telescopic rod extension or rotation. The winding module can also control the main replacement motor 372 to drive the main replacement ring 371 to rotate. When the main replacement ring 371 rotates, it will drive the main reel 37 to rotate along the arc slide. Similarly, the winding module can also control the auxiliary replacement motor 362 to drive the auxiliary replacement ring 361 to realize the auxiliary reel 36 to rotate along the arc slide. The main reel 37 and the auxiliary reel 36 can be replaced by the auxiliary replacement motor 362 and the main replacement motor 372. During the replacement process, the finished film will contact the cutter 38. Under the action of the cutter 38, the finished film will be cut, which is convenient for the auxiliary reel 36 to rewind the finished film.

[0036] In addition, the input end of the co-extruder 2 is connected to a plurality of extruders 1, each of which includes a material transport pipe 11, a spiral stirring rod 13 installed in the material transport pipe 11, and a drive motor A10. The output shaft of the drive motor A10 is connected to the spiral stirring rod 13. The spiral stirring rod 13 is driven by the drive motor A10 to rotate, and the raw material in the material transport pipe 11 is squeezed into the co-extruder 2, and the co-extruder 2 stretches the squeezed raw material into a prototype film. A feed port 12 is installed at the upper end of the material transport pipe 11, a heater A14 is arranged on the inner side of the material transport pipe 11, and a temperature sensor 15 is fixed in the spiral stirring rod 13. The intelligent signal processor also includes a temperature control module, which is connected to the control panel 4 by signal, and the temperature control module is respectively connected to the temperature sensor 1 5 is electrically connected to the heater A14. Through the above settings, since the polymer decorative film is a multi-layer film of different materials, different materials require different temperatures. The operator can set the temperatures of multiple extruders 1 respectively through the control panel 4, and then the temperature control module will control the corresponding heater A14 to control the power. When the temperature sensor three 15 detects that the temperature in the extruder 1 is much lower than the set temperature (less than the temperature range preset in the temperature control module), the temperature control module will control the corresponding heater A14 to increase the heating power. When the temperature sensor three 15 detects that the temperature is higher than or equal to the set temperature (greater than or equal to the temperature range preset in the temperature control module), the temperature control module will also control the heater A14 to reduce the power, thereby reducing energy consumption.

[0037] In addition, the molding machine 3 also includes a plurality of main extrusion rods 31, a secondary extrusion rod 311 arranged below the main extrusion rod 31, a cooling rod 33 arranged downstream of the secondary extrusion rod 311, and a guide rod 34 arranged downstream of the cooling rod 33. Through the mutual cooperation of the main extrusion rod 31 and the secondary extrusion rod 311, the prototype film produced by the co-extruder 2 can be re-extruded. A drive motor B313 is arranged on the rear side of each main extrusion rod 31, and a drive motor C332 is arranged on the rear side of the cooling rod 33. The intelligent signal processor also includes a drive module, which is electrically connected to the plurality of drive motors B313 and the drive motor C332 respectively, so that the drive module can control the switching and operating power of the plurality of drive motors B313 and the drive motor C332.

[0038] In addition, the molding machine 3 also includes a scrap rejector 35 arranged below the guide rod 34, the scrap rejector 35 includes a scrap rejector rod 350, and multiple horizontal drive motors A351 slidably connected to the scrap rejector rod 350, the scrap rejector rod 350 is provided with a slideway meshing with the rotating shaft gear of the horizontal drive motor A351, and a rejecting knife 352 is fixed on one side of each horizontal drive motor A351, and the movement of the rejecting knife 352 can be achieved through the interaction between the horizontal drive motor A351 and the scrap rejector rod 350. The intelligent signal processor also includes a scrap rejector module, which is connected to the control panel 4 by signal, and the scrap rejector module is electrically connected to the horizontal drive motor A351, so that the film width to be reserved can be set on the control panel 4, and the scrap rejector module will control the horizontal drive motor A351 to move, and adjust the spacing of the rejecting knife 352 to the set width.

[0039] The second implementation method:

[0040] See also Figure 3-Figure 11 Different from the first embodiment, a heater B312 is fixed to the periphery of each main extrusion rod 31, and the heater B312 will heat the film on the main extrusion rod 31; a temperature sensor 1 is provided in each secondary extrusion rod 311, and the temperature sensor 1 can detect the temperature of the film passing through the main extrusion rod 31; a cooler 331 is provided on the periphery of the cooling rod 33, and the cooler 331 will cool the film on the cooling rod 33; a temperature sensor 2 is provided in the guide rod 34, and the temperature sensor 2 will detect the temperature of the film on the guide rod 34; the temperature control module is electrically connected to the heater B312, the temperature sensor 1, the cooler 331 and the temperature sensor 2 respectively; when the temperature control module detects through the temperature sensor 1 that the temperature of the film on the main extrusion rod 31 is not conducive to extrusion, the heater B312 will be controlled to heat the film, so that the extrusion process of the film is more convenient; when the temperature control module detects through the temperature sensor 2 that the temperature of the film on the guide rod 34 is high, the temperature control module will control the cooler 331 to increase the cooling efficiency to prevent the film from being damaged in the subsequent process.

[0041] In addition, a plurality of distance sensors 61 are arranged between the main extrusion rods 31, and the plurality of distance sensors 61 are arranged on a plurality of film transmission paths. Each distance sensor 61 is fixed on the outer side of the rear shell 6, and the driving module is electrically connected to the plurality of distance sensors 61 respectively. When the distance sensor 61 detects that the film is not in the corresponding path, the driving module controls the corresponding motors in the driving motor C332 and the driving motor B313 to pass the power. When the distance sensor 61 detects that the film returns to the corresponding path, the driving module reduces the output power of the corresponding motor.

[0042] To sum up, in order to make the multi-layer co-extrusion production device produce better products, the temperature control module will also detect whether the temperature of the film on the main extrusion rod 31 is conducive to the extrusion of the film through the temperature sensor 1. When the temperature is not suitable, the temperature control module will control the heater B312 to heat the film to make the extrusion process of the film more convenient; when the temperature control module detects that the temperature of the film on the guide rod 34 is high through the temperature sensor 2, the temperature control module will control the cooler 331 to increase the cooling efficiency to prevent the film from being damaged in the subsequent process; in order to prevent too much film between the main extrusion rod 31 and the main extrusion rod 31 or between the main extrusion rod 31 and the cooling rod 33, thereby causing damage to the film, the drive module will detect whether the film is in the corresponding path through the distance sensor 61. When there is a film that is not in the corresponding path, the drive module will control the corresponding motors in the drive motor C332 and the drive motor B313 to pass the power. When the distance sensor 61 detects that the film returns to the corresponding path, the drive module will reduce the output power of the corresponding motor to prevent the film from being damaged by the conveying rod.

[0043] In view of current practical needs, the above-mentioned implementation mode adopted in this application is not limited to the scope of protection.
