DETAILED DESCRIPTION

[0015] The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the protection scope of the present invention.

[0016] See also Figure 1 , the utility model embodiment includes:

[0017] A curing device for high-toughness waterproof polyurethane film includes a curing chamber 26, in which two mounting platforms 27 are symmetrically arranged. After the film 25 is input from the left side of the curing chamber 26, it passes through the upper surface of the mounting platform 27 on the left side, and then passes between the two mounting platforms 27 and is output vertically from the bottom of the curing chamber 26. A segmented vertical coating structure is installed in the curing chamber 26, which can evenly coat the film 25 to ensure uniform coating of the paint.

[0018] The segmented vertical coating structure includes a coating structure for coating the film 25 , a drying structure for curing, and a transport structure for transporting the film 25 within the curing chamber 26 .

[0019] The transmission structure includes a clamping structure and an active structure. The clamping structure is installed on the upper surface of the mounting platform 27 on the left side. The clamping structure includes two first brackets 1 and a first roller 2. The two first brackets 1 are vertically symmetrically installed on the upper surface of the mounting platform 27 on the left side. A first slide groove 3 is opened on the first bracket 1. The first roller 2 is connected to the first slide groove 3 through a first slider 4. A first pressure spring 5 is installed between the top of the first slider 4 and the top of the first slide groove 3. The clamping structure is used to flatten the film 25 input into the curing chamber 26 to ensure uniform coating in the subsequent coating.

[0020] The active structure is installed on a vertical plane close to the bottom of the mounting platform 27. The active structure includes four second brackets 6 and two second rollers 7. The four second brackets 6 are vertically symmetrically installed on the opposite vertical planes of the two mounting platforms 27 in pairs. A second slide groove 8 is provided on the second bracket 6. The second roller 7 is connected to the second slide groove 8 through a second slider 9. A second pressure spring 10 is installed between the top of the second slider 9 and the top of the second slide groove 8. The second roller 7 is connected to the conveying motor 23 installed on the second slider 9 through a rotating shaft. The second roller 7 is driven to rotate by the conveying motor 23, thereby generating a pulling force on the cured film 25, so that the film 25 can move in the curing chamber 26 in turn, and finally output from the bottom of the curing chamber 26 to be transported by other conveying equipment.

[0021] The coating structure is installed on a vertical plane close to the top of the mounting platform 27. The coating structure includes four third brackets 11, two coating rollers 12 and two coating boxes 13. The four second brackets 6 are vertically symmetrically installed in pairs on the opposite vertical planes of the two mounting platforms 27. The two coating rollers 12 are symmetrically installed between the two groups of the third brackets 11. The two coating boxes 13 are symmetrically installed on the opposite vertical planes of the two mounting platforms 27. The coating left on the inclined surface 14 is brushed onto the film 25 through the bristles 18 on the surface of the coating roller 12.

[0022] The paint box 13 is provided with an inclined surface 14 and a scraper plate 15 . The inclined surface 14 is used for the paint to flow so that it can be easily lifted up by the brush bristles 18 .

[0023] An inlet 16 is provided between the bottom of the inclined surface 14 and the scraper 15, and the inlet 16 is used to collect the excess paint flowing down the inclined surface 14 and the paint hanging from the surface of the film 25 by the scraper 15 for the first leveling into the paint box 13 for reuse.

[0024] A discharge nozzle 17 is provided at the top of the paint box 13 , and the discharge nozzle 17 is connected to an internal pressure pump. The pressure pump conveys the paint in the paint box 13 out of the discharge nozzle 17 so that the paint flows down along the inclined surface 14 .

[0025] The two paint rollers 12 are connected to a paint motor 24 mounted on the third bracket 11 via a rotating shaft. The paint motor 24 drives the paint rollers 12 to rotate, so that the bristles 18 can apply the paint flowing down the inclined surface 14 to the surface of the film 25 .

[0026] The drying structure is installed on the vertical plane of the mounting platform 27, and is located between the coating structure and the transmission structure. The drying structure includes a low-temperature drying unit 19 and a high-temperature drying unit 20. The low-temperature drying unit 19 is located at the upper end of the high-temperature drying unit 20. The low-temperature drying unit 19 and the high-temperature drying unit 20 are both composed of two dryers, and the two dryers are symmetrically installed on the opposite vertical planes of the two mounting platforms 27.

[0027] The low-temperature drying unit 19 is used to preliminarily cure the coating on the surface of the film 25 to make it soft, so that the leveling structure can be leveled and then pass through the high-temperature drying unit 20 for final curing and shaping, thereby ensuring uniform coating of the coating.

[0028] A leveling structure is installed on the vertical surface of the mounting platform 27 between the low-temperature drying unit 19 and the high-temperature drying unit 20, and the leveling structure includes four fourth brackets 21 and two pressure rollers 22. The four fourth brackets 21 are installed in pairs vertically and symmetrically on the opposite vertical surfaces of the two mounting platforms 27, and the two pressure rollers 22 are symmetrically installed between the two groups of the fourth brackets 21.

[0029] The leveling structure is used to finally level the paint in a soft state, so as to ensure that the paint is uniform after curing.

[0030] The conveying motor 23 and the paint motor 24 both rotate in the left clockwise direction and the right counterclockwise direction.

[0031] The conveying motor 23 can convey the solidified film 25 downward, and the paint motor 24 can make the bristles 18 move in a relative direction to the paint flowing down the inclined surface 14, so that the paint can be picked up and coated on the film 25. If the movement in the same direction is adopted, the amount of paint attached to the bristles 18 will be less.

[0032] Each structure in the device is controlled and driven by an external control device.

[0033] Different from the prior art, the utility model is a curing device for high-toughness waterproof polyurethane film. The device adopts a segmented vertical coating structure, which can evenly coat the film and ensure uniform coating of the coating.
