DETAILED DESCRIPTION

[0021] To make the purpose, technical solution and advantages of the present invention more clear, the present invention is further described in detail below in combination with specific implementations and with reference to the accompanying drawings. It should be noted that the embodiments of the present invention and the features in the embodiments can be combined with each other without conflict.

[0022] It is to be understood that these descriptions are exemplary only and are not intended to limit the scope of the invention.

[0023] A device and method for producing a composite mica tape for cables provided by some embodiments of the present invention will be described below in conjunction with the accompanying drawings. Embodiment 1:

[0024] Combination Figure 1-Figure 11 As shown, the present invention provides a composite mica tape production device and method for cables, comprising a film coating mechanism 100 storing a sufficient amount of flame retardant, a spraying mechanism 200 installed on the film coating mechanism 100, a drying mechanism 300 installed on the film coating mechanism 100, a surplus material cutting mechanism 400 installed on the drying mechanism 300, and a compacting mechanism 500 installed on the surplus material cutting mechanism 400.

[0025] The film coating mechanism 100 includes a pressure-bearing bottom plate 110, a pressure-bearing top plate 120, a first side frame 130, a first roller 140, a main fixing pin 150, an anti-overflow cover 160, a baffle 170 and a first locking frame 180; the spray mechanism 200 includes a top pad 210, a bottom pad 220, a sealing cover 230, a first nozzle 240, a second nozzle 250 and a nozzle 260; the drying mechanism 300 includes a second side frame 310, a second roller 320, an insulating shell 330, a thermal pad 340, a heat release pipe 350, a heating component 360 and a storage component 370; the excess material cutting mechanism 400 includes a pressure-resistant end 410, a secondary fixing pin 420, a scraper 430 and an auxiliary pressure plate 440, a beam rail 510, a pad 520, a load-bearing beam 530, a leg 540, a reinforcing spring 550 and a pressure roller 560.

[0026] The film coating mechanism 100 includes a pressure-bearing bottom plate 110 disposed at the bottom of the polyester film, a pressure-bearing top plate 120 disposed at the top of the polyester film, and an anti-overflow cover 160 disposed between the pressure-bearing bottom plate 110 and the pressure-bearing top plate 120; The spraying mechanism 200 is used to spray the flame retardant coating evenly on both sides of the polyester film; The drying mechanism 300 includes two heat-insulating shells 330 disposed at the outer ends of the pressure-bearing bottom plate 110 and the pressure-bearing top plate 120, a thermal pad 340 installed inside the heat-insulating shells 330, and two second side frames 310 installed on both sides of the two heat-insulating shells 330; The excess material removal mechanism 400 includes two pressure-resistant end heads 410 installed outside the two second side frames 310 and a scraper 430 arranged inside the pressure-resistant end heads 410; The compacting mechanism 500 includes a beam rail 510 installed outside the pressure-resistant end head 410 , two load-bearing beams 530 movably installed in the two beam rails 510 , and a pressure roller 560 installed outside the load-bearing beams 530 .

[0027] Since the composite mica tape needs to use polyester film as the base film during the production process, as the polyester film goes through multiple processing steps, the evenly sprayed flame retardant coating will not be dried in time and will be detached due to the tension of the base film, which will cause defects in the processing of the tape. At the same time, the multi-step processing will also lead to an increase in energy consumption.

[0028] Therefore, the device is arranged in a vacuum environment. When the polyester film passes through the film coating mechanism 100, the drying mechanism 300, the excess material cutting mechanism 400 and the compacting mechanism 500 and is pulled outward at a uniform speed, the first nozzle 240 and the second nozzle 250 can spray the flame retardant coating on both sides of the polyester film. As the thickness of the flame retardant coating increases, when the polyester film passes through the anti-overflow cover 160, the excessively thick flame retardant coating can be initially scraped off, and the scraped coating will be stored in the pressure-bearing bottom plate 110, the pressure-bearing top plate 120, The rough material after preliminary treatment can be quickly transferred to the gap between the two thermal pads 340 in the cavity formed by the two first side frames 130 and the overflow prevention cover 160. Under the negative pressure state of 1-2, the flame retardant coating sprayed on both sides can be quickly dried. Finally, the dried flame retardant coating overflow will be cut off by two scrapers 430, so that the tape can be integrated from coating to drying and pressing at the shortest gap distance, thereby reducing excessive energy loss and ensuring the qualified rate of the tape after manufacture. Embodiment 2:

[0029] Combination Figure 3-Figure 9 As shown, based on the first embodiment, the film coating mechanism 100 further includes four first locking frames 180, two first side frames 130 installed on both sides of the pressure-bearing bottom plate 110 and the pressure-bearing top plate 120, a plurality of first rollers 140 movably installed in the inner transverse grooves of the first side frames 130, a main fixing pin 150 inserted into the inside of the first side frames 130, and a baffle 170 installed at one end of the first side frames 130; Rectangular notches are provided inside the pressure-bearing bottom plate 110 and the pressure-bearing top plate 120, and the pressure-bearing bottom plate 110 and the pressure-bearing top plate 120 are made of stainless steel; Four first locking frames 180 are installed outside the pressure-bearing bottom plate 110 , the pressure-bearing top plate 120 and the two first side frames 130 ; The spray mechanism 200 includes two covers 230, a bottom pad 220 installed in a rectangular notch inside the pressure-bearing bottom plate 110, a top pad 210 installed in a rectangular notch inside the pressure-bearing top plate 120, a second nozzle 250 installed inside the bottom pad 220, a first nozzle 240 installed inside the top pad 210, and a plurality of nozzles 260 installed in each of the first nozzle 240 and the second nozzle 250; One of the covers 230 is mounted on the top of the top pad 210, and the other cover 230 is mounted on the bottom of the bottom pad 220; The top of the bottom pad 220 is provided with an inwardly recessed groove.

[0030] By opening a groove on the top of the bottom pad 220, when the polyester film passes through the gap between the top pad 210 and the bottom pad 220, the first nozzle 240 installed in the top pad 210 and the second nozzle 250 installed in the bottom pad 220 can spray the flame retardant coating on both sides of the polyester film, and the groove on the top of the bottom pad 220 can store the excess flame retardant coating in a rated cavity. As the polyester film moves laterally at a uniform speed, both sides of the polyester film can be fully sprayed. Finally, under the restriction of the anti-overflow cover 160, the flame retardant coating on both sides of the polyester film can be initially scraped off and enter the drying mechanism 300 as quickly as possible. At this time, the double-sided flame retardant coating that has been treated with thickness can be quickly dried, thereby preventing the flame retardant coating from detaching from the polyester film. Embodiment three:

[0031] Combination Figure 7-Figure 10 As shown, based on the first embodiment, the drying mechanism 300 further includes a plurality of second rollers 320 movably mounted inside the second side frame 310, a plurality of heat release pipes 350 mounted inside the heat conductive pad 340, a group of power storage components 370 mounted inside the plurality of heat release pipes 350, and a heating component 360 mounted outside the two groups of power storage components 370; A heating resistor wire is installed inside the power storage component 370; The heating component 360 is composed of a battery, a wire and a central control chassis, and the central control chassis is connected to the two groups of power storage components 370 through the wire.

[0032] By simultaneously steaming the double-sided flame retardant coating in a vacuum environment, after the flame retardant coating on both sides of the polyester film passes through the two thermal pads 340, the two thermal pads 340 in the vacuum environment can quickly dry the flame retardant coating, thereby accelerating the curing speed of the flame retardant coating, making it convenient for the two scrapers 430 to quickly trim the edges, so as to ensure the consistency of the double-sided flame retardant coating with the size of the polyester film after curing. Embodiment 4:

[0033] Combination Fig.10 and Fig.11 As shown, on the basis of the first embodiment, the excess material removal mechanism 400 further includes a secondary fixing pin 420 installed inside the pressure-resistant end head 410, and the secondary fixing pin 420 is adapted to penetrate into the interior of the scraper 430; Two auxiliary pressure plates 440 respectively mounted on the two pressure-resistant end heads 410; The compacting mechanism 500 further includes four pads 520, and a pad is provided at one end of the pad 520, and a bolt is movably installed inside the pad; Two legs 540 fixedly mounted at both ends of the load-bearing beam 530 and a reinforcing spring 550 disposed outside the legs 540; The supporting leg 540 is composed of a rectangular end plate and a vertical rod, and the vertical rod is adapted to penetrate into the interior of the pad foot 520 , while the reinforcing spring 550 arranged outside the vertical rod fits and presses tightly on the pad foot 520 .

[0034] By setting two auxiliary pressure plates 440 symmetrically distributed between the two pressure-resistant end heads 410, when the cured double-sided flame retardant coating passes through the two auxiliary pressure plates 440, the cured flame retardant coating can be limited before compaction. Finally, under the opposite extrusion action of two pressure rollers 560, the double-sided flame retardant coating can be pressed on both sides of the polyester film, further ensuring the compactness of the flame retardant coating on both sides of the polyester film.

[0035] The working principle and use process of the present invention are as follows: the pressure roller 560 is pre-movably installed on the outside of the load-bearing beam 530, and the two ends of the load-bearing beam 530 are adapted to penetrate into the slideways inside the two beam rails 510, and two legs 540 are fixedly installed on the two ends of the load-bearing beam 530, and then the four pads 520 are fixedly installed on the inside of the two beam rails 510 by bolts and gaskets, and the rod body of the leg 540 is adapted to penetrate into the inside of the pad 520, and the outer end of the reinforcing spring 550 arranged on the rod body of the leg 540 will fit and press against the pad 520, at this time, the two pressure rollers 560 in the initial state will be pressed by the two sets of reinforcing springs 550 to press the two cured flame retardant coatings; The two beam rails 510 are fixedly mounted on the two pressure-resistant end heads 410 by bolts, respectively. At this time, the exposed gaps of the two pressure rollers 560 are located in the middle of the gaps of the two auxiliary pressure plates 440, and the two combined pressure-resistant end heads 410 are fixed to the outside of the two second side frames 310 by rivets and clamps, and the two heat-insulating shells 330 installed between the two second side frames 310 fix the two thermal pads 340. At this time, the exposed gaps of the adjacent plate surfaces of the two thermal pads 340 are symmetrical with the gaps of the two auxiliary pressure plates 440, and the two second side frames 3 10 is fixed to the two first side frames 130 by bolts and clamps, and the overflow prevention cover 160 is fixedly installed inside the two first side frames 130 by two main fixing pins 150. At this time, the overflow prevention cover 160 provides overflow protection for the cavity formed by the two first side frames 130, the pressure-bearing top plate 120 and the pressure-bearing bottom plate 110. When the device is operated in a vacuum environment as a whole, as the polyester film is delivered along the gap between the pressure-bearing bottom plate 110 and the pressure-bearing top plate 120, the actively pulled polyester film passes through the top pad At the same time, the flame retardant sprayed by the first nozzle 240 and the second nozzle 250 at high pressure will be evenly distributed on the top and bottom of the polyester film. When the thickness of the flame retardant continues to increase and passes through the anti-overflow cover 160, it is restricted by the inner frame of the anti-overflow cover 160, and the double-sided flame retardant coating can be initially scraped and trimmed until the trimmed film and the double-sided flame retardant coating enter the interior of the drying mechanism 300. The two thermal pads 340 in high-temperature steaming can heat the double-sided flame retardant coating. , and the device is under negative 1 to 2 atmospheres, so the principle of high-temperature vacuum drying is used, and the double-sided flame retardant coating can be quickly dried at this time. After the dried film and flame retardant coating enter the residual material cutting mechanism 400, the two scrapers 430 arranged on both sides of the film can cut off the residual material that overflows and exceeds the film specifications, and discharge it outward from the notch of the pressure-resistant end 410. After the material with the cut residual material is rolled by two pressing rollers 560, the solidified double-sided flame retardant coating can be prevented from falling off.

[0036] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the claims and their equivalents.

At this time, the overflow-proof cover (160) provides overflow-proof protection for the cavity formed by the two first side frames (130), the pressure-bearing top plate (120) and the pressure-bearing bottom plate (110); When the device as a whole is operated in a vacuum environment, as the polyester film is delivered along the gap between the pressure-bearing bottom plate (110) and the pressure-bearing top plate (120), the actively pulled polyester film will pass through the gap between the top pad (210) and the bottom pad (220). At the same time, the flame retardant sprayed at high pressure through the first nozzle (240) and the second nozzle (250) will be evenly distributed on the top and bottom of the polyester film.
