Description

Technical Field

[0001] The present invention relates to the technical field of vehicle film production, and more particularly to an intelligent temperature-controlled vehicle cover production line. Background Art

[0002] Car film (car cover), also known as car film or car insulation film, is a film product specially designed to be applied to car glass; The car film production line can be a process of processing a base film [such as polyester film (PET)] into a car film with specific functions (such as heat insulation, UV protection, etc.). The process is basically as follows: Unwinding: The rolled substrate film is placed at one end of the production line and unwound using an unwinding device [as shown in Publication No. CN217073357U, a unwinding device for automotive film]. Surface treatment: In order to improve the adhesion between the coating and the substrate, the PET film is sometimes subjected to corona treatment or other forms of surface modification treatment [such as Publication No. CN212555037U, a film corona treatment device] to improve adhesion; Coating process: One or more layers of functional coating are applied to the substrate film according to the desired functional properties. Drying and curing: The applied liquid is rapidly evaporated and fixed by heating, etc., to form a stable functional layer [as shown in Publication No. CN213412901U, "Online Coating and Drying Apparatus for Biaxially Stretch Film"]. Cooling and shaping: After high-temperature treatment, the film needs to be cooled appropriately to maintain its shape [as shown in Publication No. CN220280243U, a cooling device for automobile protective film production]; Winding: The last step is to collect the processed car film into a roll again [Publication (Announcement) No.: CN217971805U, A kind of car film production and winding equipment] as shown; The surface treatment before coating using corona treatment is too simple and has the disadvantage of insufficient effect in improving adhesion strength. Summary of the Invention

[0003] The purpose of the present invention is to solve the above technical problems and provide an intelligent temperature-controlled car cover production line.

[0004] In order to achieve the above-mentioned purpose, the present invention specifically adopts the following technical solutions: The present invention proposes an intelligent temperature-controlled car cover production line, which includes an unwinding device, a pretreatment device, a layer drying device, a cooling device and a winding device, which are arranged in sequence and are respectively fixed by a connecting frame. The unwinding device transmits the base film through the pretreatment device to the layer drying device; The pretreatment equipment includes a bracket fixed to the connecting frame, a controller and a housing fixed on the bracket, a first heating roller and a corona roller rotatably connected in the housing, and a high-voltage electrode, an infrared heating lamp, an exhaust pipe and an infrared temperature sensor fixed in the housing; The outer shell is provided with two relatively connected openings for the base film to pass through for transmission. The base film is laminated to the first heating roller and the corona roller for transmission. After the corona roller is laminated to the first heating roller, the output end of the high-voltage electrode is directed toward and close to the base film on the corona roller. The outer shell is non-conductive, the corona roller can generate heat, and the exhaust pipe partially passes through the outside of the outer shell and the exhaust pipe connects the inside and outside of the outer shell.

[0005] As a preferred technical solution of the present invention, the high-voltage electrode is located above the corona roller.

[0006] As a preferred technical solution of the present invention, the first heating rollers are provided in multiple groups and are distributed on both sides of the corona roller.

[0007] As a preferred technical solution of the present invention, the infrared heating lamps are provided in multiple groups and are distributed on both sides of the corona roller, and the multiple groups of first heating rollers are correspondingly located below the multiple groups of infrared heating lamps in the vertical direction.

[0008] As a preferred technical solution of the present invention, the infrared temperature sensors are provided in multiple groups and are evenly distributed in the housing.

[0009] As a preferred technical solution of the present invention, a groove is formed below the corona roller in the housing to accommodate at least one group of infrared temperature sensors.

[0010] As a preferred technical solution of the present invention, the exhaust pipes are provided in two groups and are symmetrically distributed on both sides of the high-voltage electrode.

[0011] As a preferred technical solution of the present invention, the corona roller includes an annular roller body, an insulating heat-conducting ring fixedly mounted on the inner side of the annular roller body, a second heating roller fixedly mounted on the inner side of the insulating heat-conducting ring, and a conductive ring arranged on one side of the annular roller body. The outside of the annular roller body is fixed to the conductive ring by a conductive rotating member. The conductive ring is fixedly passed through the inner and outer sides of the outer shell, and the other side of the annular roller body opposite to the conductive ring is rotatably connected to the outer shell.

[0012] The beneficial effects of the present invention are as follows: By setting up a pretreatment device, the base film is conveyed into the shell through the openings on both sides of the shell in the unwinding device, and the infrared heating lamp and the first heating roller are used to quickly heat the base film. At the same time, the high-voltage electrode is used to perform corona treatment on the base film. Such a combined application can improve the surface adhesion and reduce the volume of the overall equipment. In particular, the corona treatment of the preheated base film can further improve the intensity of the corona treatment. At the same time, the corona roller also provides heat to provide a more accurate temperature supply during the corona treatment, greatly improving the surface adhesion of the base film. The corona roller is provided, and the heat generated by the second heating roller is conducted to the annular roller body through the insulating heat-conducting ring to generate heat, which can generate heat and ensure the use during corona treatment.

DETAILED DESCRIPTION

[0015] like Figures 1-3 As shown, the present invention proposes: an intelligent temperature-controlled car cover production line, comprising an unwinding device 1, a pretreatment device 2, a coating drying device 3, a cooling device 4, and a winding device 5, which are arranged in sequence and fixed by a connecting frame 6. The unwinding device 1 transmits a base film through the pretreatment device 2 to the coating drying device 3. The base film is pretreated to improve the surface adhesion and then transferred to the coating drying device 3 for treatment, which can improve the coating effect; The pretreatment device 2 includes a bracket 21 fixed to the connecting frame 6, a controller 22 and a housing 23 fixed to the bracket 21, a first heating roller 24 (the first heating roller 24 can be an electromagnetic heating roller, etc.) and a corona roller 25 rotatably connected in the housing 23, and a high-voltage electrode 26, an infrared heating lamp 27, an exhaust pipe 28 and an infrared temperature sensor 29 fixed in the housing 23; The controller 22 (which is a PLC controller) is connected to an external power source to supply power to electrical components; The housing 23 is provided with two relatively communicating openings for the base film to pass through for transmission (eg Figure 2 As shown, the base film is placed into the housing 23 through the opening on the left side of the housing 23 and is passed out through the opening on the right side of the housing 23); The base film is laminated to the first heating roller 24 and the corona roller 25. After the corona roller 25 is laminated to the first heating roller 24, the base film is laminated to the roller side of the first heating roller 24 and the corona roller 25 during the conveying process. The first heating roller 24 and the corona roller 25 support the conveying of the base film, and the heating roller first contacts the base film to ensure the preheating effect. At the same time, the installed infrared heating lamp 27 assists in generating heat to improve the efficiency of heating the base film. The output end of the high-voltage electrode 26 is directed toward and close to the base film on the corona roller 25. The discharge from the high-voltage electrode 26 is transmitted to the base film for corona treatment. Combined with the preheating treatment of the base film, the surface adhesion can be improved and the volume of the overall equipment can be reduced. In particular, the corona treatment of the preheated base film can further improve the strength of the corona treatment. The housing 23 is non-conductive [the housing 23 may be made of polycarbonate (PC) or the like] and does not conduct electricity with electrical components to improve safety; The corona roller 25 can generate heat and provide a more accurate temperature supply, which greatly improves the surface adhesion of the base film during the corona treatment. The structure of the corona roller 25 is specifically implemented as follows, and is combined with the following Figures 1-3 As shown: The corona roller 25 includes an annular roller body 251 (the annular roller body 251 is made of a conductive material such as aluminum or stainless steel), an insulating heat-conducting ring 252 fixedly mounted on the inner side of the annular roller body 251 (the insulating heat-conducting ring 252 can be made of aluminum oxide (Al2O3) or boron nitride (BN), etc.), a second heating roller 253 fixedly mounted on the inner side of the insulating heat-conducting ring 252 (the second heating roller 253 can be an electromagnetic heating roller, etc.), and a conductive ring 254 (the conductive ring 254 can be made of stainless steel, etc.) surrounding the outer side of the annular roller body 251. The outer surface of the annular roller 251 is fixed to the conductive ring 254 via a conductive rotating member, which can be a conductive bearing or the like (the conductive bearing can be made of stainless steel or other materials); The conductive ring 254 is fixedly passed through the inner and outer sides of the housing 23. The other side of the annular roller 251 opposite the conductive ring 254 is rotatably connected to the housing 23. The conductive ring 254 passes through the inner and outer sides of the front end of the housing 23 and is fixed. The rear end of the annular roller 251 can be rotatably connected to the housing 23 using a rotating member such as a bearing. When the corona roller 25 is in use, the heat generated by the second heating roller 253 is transferred to the annular roller body 251 through the insulating heat-conducting ring 252 to generate heat. During the corona treatment, the conductive ring 254 is connected to the conductive rotating member and the annular roller body 251 through an external ground wire to form a ground electrode, which can generate heat and ensure the use during the corona treatment. The exhaust pipe 28 partially passes through the outside of the shell 23 and the exhaust pipe 28 communicates with the inside and outside of the shell 23. The outer end of the exhaust pipe 28 is connected to the exhaust component to discharge the ozone and other gases generated in the shell 23 during corona discharge to the outside. Infrared temperature sensor 29 (which can be MLX90614 infrared sensor) detects the heat source in the housing 23 and can promptly understand when a large change in heat occurs; When the infrared temperature sensor 29 is used in a specific application, an existing feasible example is as follows: a microprocessor and a wireless remote transceiver module are installed in the controller 22 (the wireless remote transceiver module can be Bluetooth, etc., to connect to the user's smart terminal, such as a smart phone, etc.), and the microprocessor is electrically connected to the infrared temperature sensor 29. After detecting the temperature change, the information can be quickly transmitted to the user's smart terminal, so that the information can be obtained in time.

[0016] like Figure 2 As shown: the high-voltage electrode 26 is located above the corona roller 25, and the base film is located between the high-voltage electrode 26 and the corona roller 25 for corona treatment.

[0017] like Figure 2 As shown: There are multiple groups of first heating rollers 24 and they are distributed on both sides of the corona roller 25. Multiple groups of first heating rollers 24 are symmetrically arranged on the left and right sides of the corona roller 25 to guide and transport the base film left and right, and preheat the base film before corona treatment and stabilize the heat after corona treatment to ensure good subsequent processing effects.

[0018] like Figure 2 As shown: there are multiple groups of infrared heating lamps 27 and they are distributed on both sides of the corona roller 25, and the multiple groups of first heating rollers 24 are correspondingly located below the multiple groups of infrared heating lamps 27 in the vertical direction, and multiple groups of infrared heating lamps 27 are symmetrically arranged on the left and right sides of the corona roller 25. The multiple groups of infrared heating lamps 27 are inclined, the multiple groups of first heating rollers 24 are inclined, and the multiple groups of first heating rollers 24 are inclined below the multiple groups of infrared heating lamps 27, so as to provide heat on the top of the base film, and the heating effect is good.

[0019] like Figure 2 As shown, multiple groups of infrared temperature sensors 29 are provided and evenly distributed in the housing 23, providing multi-position temperature sensing and good monitoring effect.

[0020] A groove is formed below the corona roller 25 in the housing 23 for accommodating at least one set of infrared temperature sensors 29. The infrared temperature sensor 29 is installed at the bottom of the groove to sense the temperature change of the corona roller 25, with high monitoring accuracy.

[0021] like Figure 2 As shown: there are two groups of exhaust pipes 28 and they are symmetrically distributed on both sides of the high-voltage electrode 26. The exhaust pipes 28 are placed on the left and right sides of the high-voltage electrode 26 to absorb the ozone generated on the left and right sides of the high-voltage electrode 26, and the suction surface is large.

[0022] The control method of the present invention is automatic control through a controller. The control circuit of the controller can be implemented by simple programming by a person skilled in the art. The provision of power is also common knowledge in the art. The present invention is mainly used to protect mechanical devices, so the control method and circuit connection are not explained in detail in the present invention.

It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention.
