DETAILED DESCRIPTION

[0029] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0030] like Figures 1 to 8 As shown, the present invention provides a degreasing device for treating residual kerosene of a PTFE dispersed resin film, comprising a device body 1, a cleaning compartment 2, a coating compartment 3 and a degreasing compartment 4 are provided inside the device body 1, a cleaning mechanism 5 is provided inside the cleaning compartment 2, a coating mechanism 6 is provided inside the coating compartment 3, a hot air device 7 is installed on the side of the degreasing compartment 4, an exhaust device 8 is installed on the top of the degreasing compartment 4, a water inlet pipe 9 and a water outlet pipe 10 are fixedly connected to both sides of the cleaning compartment 2, a material roller 11 is installed on both sides of the device body 1, a film 12 is wound on the middle of the material roller 11, and a wiper 13 is fixedly connected to the coating compartment 3;

[0031] The cleaning mechanism 5 includes a limit bracket 51, and limit grooves 52 are provided on both sides of the limit bracket 51. A soft hair roller 53 is slidably connected inside the limit groove 52. Cylinders 54 are fixedly connected to both sides of the limit bracket 51. A double-sided tooth plate 55 fixedly connected to the inner wall of the device body 1 is provided on the side of the limit bracket 51, and a spur gear 56 is fixedly connected to one end of the limit groove 52 close to the double-sided tooth plate 55.

[0032] The above scheme is adopted: the film 12 is guided into the cleaning compartment 2 by the conveying roller, the soft-hair roller 53 slides left and right, and the spur gear 56 slides along the double-sided toothed plate 55, so that the soft-hair roller 53 rotates to clean both sides of the film 12; then the film 12 enters the coating compartment 3, the surface of the film 12 is first wiped by the wiper 13, and then the film 12 enters between a pair of spray pipes 621, and the support frame 61 drives the spray pipe 621 to swing through the teeth, so that the spray pipe 621 swings to the elastic limit position. When the rod 623 collides with the limit plate 66, the degreasing agent is sprayed onto the surface of the film 12 through the nozzle 622, and then the film 12 moves to the soft-bristle brush 65. Under the horizontal reciprocating movement driven by the soft-bristle brush 65 and the support frame 61, the degreasing agent is evenly scraped on the surface, and then enters the degreasing compartment 4. The hot air device 7 sends in hot air with a suitable temperature to evaporate the residual kerosene and the degreasing agent on the surface of the film 12, thereby completing the degreasing treatment of the film 12 and cleaning the dust on the surface of the film 12.

[0033] like Figure 1 , Figure 2 and Figure 8 As shown, a plurality of conveying rollers are arranged inside the device body 1, the coating compartment 3 is respectively connected with the cleaning compartment 2 and the degreasing compartment 4, the water inlet pipe 9 is located on the upper side of the water outlet pipe 10, the film 12 enters the device body 1 from the cleaning compartment 2 and passes through the cleaning compartment 2, the coating compartment 3 and the degreasing compartment 4, and the wiper 13 is in conflict with the film 12.

[0034] The above scheme is adopted: by arranging multiple conveying rollers inside the device body 1, and connecting the coating compartment 3 with the cleaning compartment 2 and the degreasing compartment 4, it is convenient to convey the film 12 between the cleaning compartment 2, the coating compartment 3 and the degreasing compartment 4, so that the film 12 can be directly coated with the degreasing agent after cleaning, and then directly heated and degreased, thereby reducing the repeated winding and conveying process. The water inlet pipe 9 and the water outlet pipe 10 are arranged to keep the clean water inside the cleaning compartment 2 flowing to avoid dust accumulation inside the cleaning compartment 2. The wiper 13 arranged inside the coating compartment 3 can remove most of the clean water remaining on the surface of the film 12 when the film 12 enters the coating compartment 3 after being cleaned inside the cleaning compartment 2, thereby avoiding dilution of the degreasing agent applied subsequently.

[0035] like Figure 2 , Figure 3 and Figure 4 As shown, the limit bracket 51 is slidably connected to the inside of the device body 1 and passes through the top of the cleaning compartment 2 and extends to the inside of the coating compartment 3. Both sides of the limit bracket 51 pass through the outer wall of the device body 1 and extend to the outside of the device body 1. The limit groove 52 is in a horizontal figure eight shape. The soft hair roller 53 is distributed on the upper and lower sides of the film 12. The cylinder 54 is located on the outside of the device body 1 and the bottom is fixedly connected to the device body 1. The double-sided tooth plate 55 is meshed with the spur gear 56.

[0036] The above scheme is adopted: by setting a limit bracket 51 to pass through the partition between the cleaning compartment 2 and the smearing compartment 3, the limit bracket 51 can slide conveniently, and the two sides of the limit bracket 51 are set to pass through the outer wall of the device body 1, the device body 1 can limit and support the limit bracket 51, and the limit groove 52 is set to a horizontal figure eight shape, so that when the soft hair roller 53 slides inside the limit groove 52, the sliding direction is opposite, and the soft hair roller 53 is set on both sides of the film 12, so that the soft hair roller 53 can clean both sides of the film 12 at the same time, and when the soft hair roller 53 slides, the soft hair roller 53 will drive the clean water inside the cleaning compartment 2 to shake, and drive the dust cleaned on the film 12 to move, and at the same time, the soft hair roller 53 is meshed with the double-sided toothed plate 55 through the spur gear 56, so that the soft hair roller 53 will rotate when sliding, providing a better cleaning effect.

[0037] like Figure 5 , Figure 6 and Figure 7 As shown, the coating mechanism 6 includes a support frame 61 and a pair of spray assemblies 62. The support frame 61 has a turntable 63 on its side, and the turntable 63 is meshingly connected with a single-sided toothed plate 64. A soft-bristle brush 65 is fixedly connected to one end of the support frame 61 close to the film 12, and a limiting plate 66 is provided on the side away from each other of the pair of spray assemblies 62.

[0038] The above scheme is adopted: by setting up a support frame 61, the support frame 61 can drive the soft-bristle brush 65 to slide, so that the soft-bristle brush 65 can evenly scrape the degreaser on both sides of the film 12. The setting of the turntable 63 and the single-sided tooth plate 64 can drive the turntable 63 to rotate by the single-sided tooth plate 64, and then the rotation of the turntable 63 drives the support frame 61 to slide back and forth. The limit plate 66 is used to contact the elastic limit rod 623 with the elastic limit rod 623, so that the elastic limit rod 623 moves.

[0039] like Figure 5 , Figure 6 and Figure 7As shown, the support frame 61 is slidably connected to the inner wall of the device body 1, a slide groove is opened in the middle of the support frame 61, and teeth are arranged at the connection between the support frame 61 and the spray assembly 62. The turntable 63 is located between the support frame 61 and the device body 1 and is rotatably connected to the device body 1. A limiting rod is arranged on a side of the turntable 63 close to the support frame 61, and the limiting rod is slidably connected to the inside of the slide groove in the support frame 61. The single-sided tooth plate 64 is fixedly connected to the top of the limiting bracket 51, and the spray assembly 62 and the soft-bristle brush 65 are distributed on both sides of the film 12 in a mirror-like manner, and the inner side of the limiting plate 66 is arc-shaped.

[0040] The above scheme is adopted: by setting a slide groove in the middle of the support frame 61, the turntable 63 can be pushed to slide back and forth in the horizontal direction through the limit rod on the turntable 63 when it rotates, so that the support frame 61 drives the spray pipe 621 to swing through the teeth and half gear 626 on the upper and lower sides, and the single-sided toothed plate 64 is set on the top of the limit bracket 51, so that the sliding speed of the support frame 61 matches the sliding speed of the soft-hair roller 53, which is convenient for controlling both at the same time, and by setting the spray assembly 62 and the soft-hair brush 65 in pairs on both sides of the film 12, the degreasing agent can be applied to both sides of the film 12 at the same time, and the inner side of the limit plate 66 is arc-shaped, which can facilitate the elastic limit rod 623 to swing through the limit plate 66 without getting stuck.

[0041] like Figure 5 , Figure 6 and Figure 7 As shown, the spray assembly 62 includes a spray pipe 621, and a plurality of nozzles 622 are linearly distributed on one side of the spray pipe 621 close to the film 12. An elastic limiting rod 623 is slidably connected inside the spray pipe 621, and a sealing baffle 624 is fixedly connected to one end of the elastic limiting rod 623 close to the nozzle 622. A liquid replenishing channel 625 is provided at one end of the spray pipe 621 away from the support frame 61, and a half gear 626 is fixedly connected to one end of the spray pipe 621 close to the support frame 61. The spray pipe 621 is rotatably connected to the device body 1, and the spray pipe 621 is located on one side of the support frame 61 close to the feeding end of the film 12, and one end of the elastic limiting rod 623 away from the nozzle 622 passes through the elastic limiting rod 623 and extends to the outside of the spray pipe 621.

[0042] The above scheme is adopted: by setting up a spray assembly 62, the swing of the spray pipe 621 drives the nozzle 622 to adjust the spray direction, and the setting of the elastic limiting rod 623 can facilitate the control of the spraying frequency of the nozzle 622. Only when the elastic limiting rod 623 conflicts with the limiting plate 66, the elastic limiting rod 623 slides, and then pushes the sealing baffle 624 to move, the nozzle 622 can be unblocked and spray liquid. The design of the sealing baffle 624 is used to block the liquid inlet channel of the nozzle 622. The spray pipe 621 is set on the side of the support frame 61 close to the feeding end of the film 12, and the order of spraying first and then scraping is maintained.

[0043] like Figure 5 , Figure 6 and Figure 7 As shown, the elastic limiting rod 623 is in conflict with the limiting plate 66, the sealing baffle 624 is in conflict with the inner wall of the spray pipe 621, the infusion channel 625 is externally connected to the infusion pipeline, and the half gear 626 is meshed with the teeth on the support frame 61. When the limiting bracket 51 pushes the single-sided toothed plate 64 to move upward, the single-sided toothed plate 64 drives the turntable 63 to rotate, thereby pushing the support frame 61 to reciprocate, and the support frame 61 drives the spray pipe 621 to swing through the teeth and the half gear 626.

[0044] The above scheme is adopted: by setting up a liquid replenishment channel 625, the degreasing agent inside the spray pipe 621 can be replenished in real time, and by adding a pressurizing device on the outside of the infusion channel, a certain pressure can be maintained inside the spray pipe 621, and the half gear 626 is engaged with the teeth on the support frame 61, so that the spray pipe 621 is affected by the sliding frequency of the support frame 61, and then the swing speed and frequency of the spray pipe 621 can be controlled, thereby controlling the spray amount of the degreasing agent.

[0045] The working principle and use process of the present invention are as follows: when working, the film 12 is released by the material roller 11 and enters the inside of the device body 1, and is firstly entered into the inside of the cleaning compartment 2 by the guidance of the conveying roller, and passes through between the soft-hair rollers 53. At this time, the cylinder 54 will start to reciprocate and retract, so that the limit bracket 51 moves up and down, and then the soft-hair roller 53 is pressurized by the limit bracket 51 and slides left and right along the limit groove 52. At the same time, the spur gear 56 slides along the double-sided tooth plate 55, so that the soft-hair roller 53 rotates to clean both sides of the film 12;

[0046] Then the film 12 enters the coating compartment 3, and the surface of the film 12 is first wiped by the wiper 13, and then the film 12 enters between a pair of spray pipes 621. At this time, the cylinder 54 still pushes the limit bracket 51 to move up and down reciprocatingly, so that the single-sided toothed plate 64 moves synchronously, and then the support frame 61 is driven to rotate by the turntable 63 to make the horizontal reciprocating movement, and the spray pipe 621 is driven by the support frame 61 to swing through the teeth, so that when the spray pipe 621 swings to the elastic limit rod 623 and the limit plate 66 conflicts, the degreasing agent is sprayed to the surface of the film 12 through the nozzle 622, and then the film 12 moves to the soft-bristle brush 65, and the degreasing agent is evenly scraped on the surface under the horizontal reciprocating movement driven by the soft-bristle brush 65 and the support frame 61, and then it will enter the interior of the degreasing compartment 4, and the hot air device 7 will send hot air with suitable temperature to evaporate the residual kerosene and the degreasing agent on the surface of the film 12 together to complete the degreasing process.
