Description

Technical Field

[0001] This invention relates to a multilayer co-extrusion production apparatus, and more particularly to a temperature-controlled multilayer co-extrusion production apparatus for polymer decorative films applied in the field of polymer decorative film production technology. Background Technology

[0002] Polymer decorative film is a new type of decorative material made from polymers. By adding various additives and then going through processes such as calendering and compounding, it can have a variety of decorative effects and functions, and is therefore widely used in construction, furniture, home appliances and other fields.

[0003] The invention patent with publication number CN115972529B discloses a multilayer co-extrusion cast film production device. The invention includes multiple extruders, a die head and a forming machine used in conjunction with the extruders, and an edge trimming mechanism. The edge trimming mechanism includes a connecting rod, which is fixedly connected between the two sides of the forming machine. Sliding sleeves are slidably connected around the connecting rod. This invention uses a slitting blade to cut off the edge material of the raw material. At the same time, the position of the slitting blade can be adjusted to improve the flexibility of product use. However, the adjustment of the slitting blade requires manual intervention, which increases the input of human resources. Furthermore, the sharpness test of the cutting blade requires stopping the machine, which affects production efficiency.

[0004] To address the issues of manual adjustment of the cutting blade position, difficulty in secondary slitting, and the need for manual shutdown for sharpness testing in existing multi-layer co-extrusion production equipment, this solution proposes a temperature-controlled multi-layer co-extrusion production device for polymer decorative films. Summary of the Invention

[0005] In view of the above-mentioned prior art, the technical problems to be solved by the present invention are the problems of manual adjustment of the cutting blade position, difficulty in secondary division, and the need for manual shutdown for sharpness testing in existing multi-layer co-extrusion production equipment.

[0006] To address the aforementioned problems, this invention provides a temperature-controlled polymer decorative film multilayer co-extrusion production apparatus, comprising a co-extruder, a forming machine disposed below the co-extruder, a rear housing and a front housing both disposed around the forming machine, a control panel and an intelligent signal processor both mounted on the front housing; the forming machine includes a main winding machine and a winding drum mounted at the end of the main winding machine, a main divider and a secondary divider disposed around the main winding machine, each of the main and secondary dividers including a support rod, multiple horizontal drive motors B disposed on the support rod, and a dividing blade fixed on the housing of each horizontal drive motor B, a force sensor installed at the connection between the housing of each horizontal drive motor B and the dividing blade, a rotating shaft gear installed at the output end of the horizontal drive motor B, a slide rail meshing with the rotating shaft gear in the support rod, a replacement motor installed on one side of the support rod, and a replacement rod meshing with the gear at the output end of the replacement motor disposed on the inner side of the rear housing; the intelligent signal processor includes a take-up module, which is signal-connected to the control panel, and electrically connected to the replacement motor, the force sensor and the horizontal drive motors B respectively.

[0007] In the aforementioned temperature-controlled polymer decorative film multilayer co-extrusion production device, automatic adjustment of the cutting blade distance, simplified processing method for secondary segmentation of polymer decorative film, and automatic detection of sharpness are realized.

[0008] As a further improvement of this application, the forming machine also includes an auxiliary winding unit and a cutter disposed between the auxiliary winding unit and the main winding unit. Both the main winding unit and the auxiliary winding unit are provided with telescopic rods, and winding drums are sleeved on the telescopic rods of both the main winding unit and the auxiliary winding unit. The housing of the auxiliary winding unit is fixed with an auxiliary replacement ring, and the housing of the main winding unit is fixed with a main replacement ring. The inner ring of the auxiliary replacement ring is provided with teeth that mesh with the rotor gear on the output end of the auxiliary replacement motor, and the inner ring of the main replacement ring is provided with teeth that mesh with the rotor gear on the output end of the main replacement motor. The winding module is electrically connected to the main winding unit, the auxiliary winding unit, the auxiliary replacement motor, and the main replacement motor, respectively.

[0009] As a further improvement of this application, the input end of the co-extruder is connected to multiple extruders. Each extruder includes a feed pipe, a spiral stirring rod installed in the feed pipe, and a drive motor A. The output shaft of the drive motor A is connected to the spiral stirring rod. A feed inlet is installed at the upper end of the feed pipe. A heater A is installed inside the feed pipe. A temperature sensor three is fixed in the spiral stirring rod. The intelligent signal processor also includes a temperature control module. The temperature control module is signal-connected to the control panel and electrically connected to the temperature sensor three and the heater A, respectively.

[0010] As a further improvement of this application, the molding machine also includes multiple main extrusion rods, a secondary extrusion rod disposed below the main extrusion rods, a cooling rod disposed downstream of the secondary extrusion rods, and a guide rod disposed downstream of the cooling rods. Each main extrusion rod is provided with a drive motor B on its rear side, and the cooling rod is provided with a drive motor C on its rear side. The intelligent signal processor also includes a drive module, which is electrically connected to the multiple drive motors B and drive motors C respectively.

[0011] As another improvement of this application, the molding machine also includes an edge material rejector disposed below the guide rod. The edge material rejector includes an edge material rejecting rod and a plurality of horizontal drive motors A slidably connected to the edge material rejecting rod. The edge material rejecting rod is provided with a slide rail that meshes with the gear of the shaft of the horizontal drive motor A. Each horizontal drive motor A has a rejecting blade fixed on one side. The intelligent signal processor also includes an edge material rejecting module. The edge material rejecting module is signal connected to the control panel and electrically connected to the horizontal drive motor A.

[0015] In summary, during normal operation, the operator can input the required width of the polymer decorative film onto the control panel. The winding module automatically adjusts the spacing of the slitting blades via the horizontal drive motor B, achieving automatic adjustment of the cutting blade distance. This process also cuts the take-up roll, simplifying the secondary slitting of the film. As the amount of finished film on the main take-up unit increases, the winding module also controls the replacement motor of the main slitting unit to periodically adjust the distance between itself and the main take-up unit. When the winding module detects insufficient sharpness of the slitting blades on the main slitting unit via the force sensor, it drives the corresponding replacement motor to replace the main and auxiliary slitting units, and prompts the operator on the control panel to maintain the slitting blades of the main slitting unit. This method achieves automatic detection of slitting blade sharpness. Attached Figure Description

[0029] The two embodiments of this application will be described in detail below with reference to the accompanying drawings.

[0030] First implementation method:

[0031] Please see Figures 1-10 A temperature-controlled polymer decorative film multilayer co-extrusion production device includes a co-extruder 2, a molding machine 3 disposed below the co-extruder 2, a rear shell 6 and a front shell 5 both disposed around the molding machine 3, a control panel 4 and an intelligent signal processor both mounted on the front shell 5;

[0032] The forming machine 3 includes a main winding unit 37 and a winding drum 363 installed at the end of the main winding unit 37. The winding drum 363 is made of an easily slit material found in existing winding drums and is used for winding the finished film. A main divider 39 and a secondary divider 32 are arranged around the main winding unit 37. Both the main divider 39 and the secondary divider 32 include a support rod 390, multiple horizontal drive motors B395 mounted on the support rod 390, and a dividing blade 394 fixed on the housing of each horizontal drive motor B395. A force sensor 393 is installed at the connection between the housing of each horizontal drive motor B395 and the dividing blade 394. This force sensor 393 is a high-precision force sensor that can determine the sharpness of the dividing blade 394 by the magnitude of the force. The horizontal drive motor B395 has a rotating shaft gear installed at its output end. A slide rail that meshes with the rotating shaft gear is provided in the support rod 390. By installing the horizontal drive motor B395 on the dividing blades 394, the distance between the dividing blades 394 can be automatically adjusted. A replacement motor 391 is installed on one side of the support rod 390. A replacement rod 392 that meshes with the gear at the output end of the replacement motor 391 is provided on the inner side of the rear housing 6. A slide rail that matches the main divider 39 and the auxiliary divider 32 is provided in the rear housing 6. 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 move along the slide rail on the rear housing 6.

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

[0034] In summary, during normal operation of this multi-layer co-extrusion production unit, operators can input the corresponding value on the control panel 4 according to the width requirements of the polymer decorative film. The winding module will automatically adjust the spacing of the dividing blades 394 through the horizontal drive motor B395 to cut the polymer decorative film. This process also cuts the take-up drum 363 to facilitate the subsequent packaging of finished products. As more and more finished films accumulate on the main take-up coil 37, the winding module will also control the replacement motor 391 of the main divider 39 to periodically adjust the distance between it and the main take-up coil 37. When the winding module detects that the dividing blades 394 of the main divider 39 are not sharp enough through the force sensor 393, the winding module will drive the corresponding replacement motor 391 to replace the main divider 39 and the auxiliary divider 32, and prompt the operator on the control panel 4 to maintain the dividing blades 394 of the main divider 39.

[0035] In addition, the forming machine 3 also includes a secondary winding unit 36 ​​and a cutter 38 disposed between the secondary winding unit 36 ​​and the main winding unit 37. Both the main winding unit 37 and the secondary winding unit 36 ​​are equipped with telescopic rods. The main winding unit 37 and the secondary winding unit 36 ​​can control the extension and retraction of the corresponding telescopic rods, and can also control the rotation of the corresponding telescopic rods. A winding drum 363 is sleeved on the telescopic rods of both the main winding unit 37 and the secondary winding unit 36. A secondary replacement ring 361 is fixed to the housing of the secondary winding unit 36, and a main replacement ring 371 is fixed to the housing of the main winding unit 37. The inner ring of the secondary replacement ring 361 is provided with teeth that mesh with the rotor gear on the output end of the secondary replacement motor 362. The secondary replacement motor 362 is fixed inside the rear housing 6. The inner ring of the main replacement ring 371 is provided with teeth that mesh with the rotor gear on the output end of the main replacement motor 372. The main replacement motor 372 is fixed inside the rear housing 6. The rear housing 6 has an opening for... The auxiliary winder 36 and the main winder 37 are matched with arc-shaped slides. The take-up module is electrically connected to the main winder 37, the auxiliary winder 36, the auxiliary replacement motor 362, and the main replacement motor 372 respectively. The take-up module can control the auxiliary winder 36 and the main winder 37 to extend or rotate the corresponding telescopic rods. The take-up 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 winder 37 to rotate along the arc-shaped slide. Similarly, the take-up module can also control the auxiliary replacement motor 362 to drive the auxiliary replacement ring 361 to make the auxiliary winder 36 rotate along the arc-shaped slide. The main winder 37 and the auxiliary winder 36 can be replaced through the auxiliary replacement motor 362 and the main replacement motor 372. During the replacement process, the finished film will come into contact with the cutter 38. Under the action of the cutter 38, the finished film will be cut, which makes it convenient for the auxiliary winder 36 to wind the finished film.

[0036] In addition, the input end of the co-extruder 2 is connected to multiple extruders 1. Each extruder 1 includes a feed pipe 11, a spiral stirring rod 13 installed in the feed pipe 11, and a drive motor A10. The output shaft of the drive motor A10 is connected to the spiral stirring rod 13. By driving the spiral stirring rod 13 to rotate through the drive motor A10, the raw material in the feed pipe 11 is extruded into the co-extruder 2. The co-extruder 2 then stretches the extruded raw material into a preliminary film. The upper end of the feed pipe 11 is equipped with a feed inlet 12. A heater A14 is provided inside the feed pipe 11. A temperature sensor 15 is fixed in the spiral stirring rod 13. The intelligent signal processor also includes a temperature control module. The temperature control module is signal-connected to the control panel 4. The temperature control module is connected to the temperature sensor 15. 5 is electrically connected to heater A14. With the above settings, since the polymer decorative film is a multi-layered film of different materials, different materials require different temperatures. The operator can set the temperature of multiple extruders 1 separately through the control panel 4. Then the temperature control module will control the power of the corresponding heater A14. When the temperature sensor 3 15 detects that the temperature inside the extruder 1 is much lower than the set temperature (less than the preset temperature range in the temperature control module), the temperature control module will control the corresponding heater A14 to increase the heating power. When the temperature sensor 3 15 detects that the temperature is higher than or equal to the set temperature (greater than or equal to the preset temperature range 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 forming machine 3 also includes multiple main extrusion rods 31, a secondary extrusion rod 311 located below the main extrusion rods 31, a cooling rod 33 located downstream of the secondary extrusion rods 311, and a guide rod 34 located downstream of the cooling rods 33. Through the cooperation of the main extrusion rods 311 and the secondary extrusion rods 311, the prototype film produced in the co-extruder 2 can be extruded again. Each main extrusion rod 31 is equipped with a drive motor B313 at its rear side, and the cooling rod 33 is equipped with a drive motor C332 at its rear side. The intelligent signal processor also includes a drive module, which is electrically connected to the multiple drive motors B313 and C332 respectively, thereby enabling the drive module to control the switching and operating power of the multiple drive motors B313 and C332.

[0038] In addition, the molding machine 3 also includes an edge material rejector 35 disposed below the guide rod 34. The edge material rejector 35 includes an edge material rejecting rod 350 and multiple horizontal drive motors A351 slidably connected to the edge material rejecting rod 350. The edge material rejecting rod 350 is provided with a slide rail that meshes with the gear of the shaft of the horizontal drive motor A351. Each horizontal drive motor A351 has a rejecting blade 352 fixed on one side. The interaction between the horizontal drive motor A351 and the edge material rejecting rod 350 enables the rejection blade 352 to move. The intelligent signal processor also includes an edge material rejecting module. The edge material rejecting module is signal-connected to the control panel 4 and electrically connected to the horizontal drive motors A351. Thus, the desired film width can be set on the control panel 4, and the edge material rejecting module will control the horizontal drive motors A351 to move, adjusting the spacing of the rejection blades 352 to the set width.

[0039] Second implementation method:

[0040] Please see Figures 3-11 Unlike the first embodiment, each main extrusion rod 31 is equipped with a heater B312, which heats the film on the main extrusion rod 31. Each auxiliary extrusion rod 311 is equipped with a temperature sensor, which detects the temperature of the film passing through the main extrusion rod 31. A cooler 331 is provided around the cooling rod 33, which cools the film on the cooling rod 33. A temperature sensor 2 is provided in the guide rod 34, which detects 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. When the temperature control module detects through the temperature sensor 1 that the temperature of the film on the main extrusion rod 31 is unfavorable for extrusion, it controls the heater B312 to heat the film, making the film extrusion process 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 too high, it controls the cooler 331 to increase the cooling efficiency to prevent the film from being damaged in subsequent processes.

[0041] In addition, multiple distance sensors 61 are arranged between the main extrusion rods 31. These multiple distance sensors 61 are arranged on multiple membrane transfer paths. Each distance sensor 61 is fixed on the outside of the rear housing 6. The drive module is electrically connected to each of the multiple distance sensors 61. When the distance sensor 61 detects that the membrane is not on the corresponding path, the drive module will control the power of the corresponding motor in drive motor C332 and drive motor B313. When the distance sensor 61 detects that the membrane has returned to the corresponding path, the drive module will reduce the output power of the corresponding motor.

[0042] In summary, to ensure the multi-layer co-extrusion production unit produces higher-quality products, the temperature control module uses temperature sensor 1 to detect whether the temperature of the film on the main extrusion rod 31 is conducive to film extrusion. When the temperature is unsuitable, the temperature control module controls heater B312 to heat the film, making the film extrusion process more convenient. When the temperature control module detects that the temperature of the film on the guide rod 34 is too high through temperature sensor 2, the temperature control module controls cooler 331 to increase cooling efficiency to prevent the film from being damaged in subsequent processes. To prevent excessive film between main extrusion rods 31 or between main extrusion rods 31 and cooling rod 33, which could cause film damage, the drive module uses distance sensor 61 to detect whether the film is on the corresponding path. When film is not on the corresponding path, the drive module controls the power of the corresponding motor in drive motor C332 and drive motor B313. When distance sensor 61 detects that the film has returned to the corresponding path, the drive module reduces the output power of the corresponding motor to prevent the film from being damaged by the conveyor rod.

[0043] In light of current practical needs, the above-described embodiments adopted in this application are not limited to these. Any changes made within the scope of knowledge possessed by those skilled in the art without departing from the concept of this application still fall within the protection scope of this invention.
