[0033] Epoxy resin is a polymer macromolecule, which refers to a class of polymers containing more than two epoxy groups in the molecule. It is the polycondensation product of epichlorohydrin and bisphenol A or polyol. Due to the chemical activity of the epoxy group, it can be opened with a variety of compounds containing active hydrogen, cured and cross-linked to form a network structure, so it is a thermosetting resin. Bisphenol A type epoxy resin not only has the largest output and the most complete varieties, but also new modified varieties are still increasing and the quality is constantly improving.

[0034] When epoxy resin products are used, they are often applied by coating. For example, the Chinese utility model patent application with publication date of November 15, 2022 and publication number CN217797105U proposes a new epoxy resin coating device, in which a pneumatic rod is added to the pneumatic pump and connected to the rear end of the feed block, and the coating block is installed at the bottom of the feed hopper. This device can automatically apply epoxy resin, reduce the workload of staff, and further improve the work efficiency of staff.

[0035] In the prior art, dust may stick to the coating surface before coating, which may cause uneven coating and reduce the coating quality.

[0036] Based on this, in order to improve the problem of uneven coating caused by dust sticking to the coating, the embodiments of the present application provide the following solution.

[0037] Please also read Figure 1 and Figure 2 The embodiment of the present application provides an epoxy resin coating device, comprising a frame 1, a spreading roller 2, a receiving roller 3 and a coating mechanism, wherein the spreading roller 2 is rotatably connected to the frame 1, and the receiving roller 3 is rotatably connected to the other end of the frame 1;

[0038] The coating mechanism includes a cleaning component 41, a drying component 43, and a coating component 42. The cleaning component 41 includes a bracket 411, a first transmission roller 412, and a cleaning plate 413. The bracket 411 is connected to the frame 1 by bolts, the first transmission roller 412 is rotatably connected to the bracket 411, the cleaning plate 413 is connected to the bracket 411 by bolts, and a brush 414 is provided on the side of the cleaning plate 413 facing the first transmission roller 412. The drying component 43 is connected to the frame 1 by bolts, and the coating component 42 is connected to the frame 1 by bolts. The coating component 42 is used to coat the cloth, and the drying component 43 is used to dry the coating after coating.

[0039] From the above, it can be seen that an epoxy resin coating device provided in an embodiment of the present application, during coating, a cloth roll is passed through the unwinding roller 2, and the starting end of the cloth roll is pulled to move so that the starting end of the cloth roll passes between the first transmission roller 412 and the brush 414, and then the starting end of the cloth roll is continued to be pulled so that the cloth roll passes through the coating component 42 and the drying component 43 in turn, and the starting end of the cloth roll is wound around the receiving roller 3, and then epoxy resin is added to the coating component 42. When the receiving roller 3 rotates, the coated cloth can be rolled up.

[0040] An epoxy resin coating device provided in an embodiment of the present application, due to the arrangement of the first drive roller 412 and the brush 414, can clean the cloth roll before it enters the coating component 42, and brush off the dust accumulated on the cloth roll, so that the cloth roll can be coated more evenly during coating, thereby improving the coating quality.

[0041] In some embodiments, please refer to Figure 1 and Figure 2 In some embodiments, the coating assembly 42 includes a coating table 421 and a material discharge box 422. The coating table 421 is connected to the frame 1 by bolts. Slide grooves are provided on the inner walls of both sides of the coating table 421. Slide columns 423 are connected on both sides of the material discharge box 422 by bolts. The material discharge box 422 is slidably connected to the coating table 421 through the slide columns 423. A through hole 427 is provided on the bottom surface of the material discharge box 422.

[0042] With such arrangement, before the cloth is coated, the discharge box 422 can slide on the coating platform 421 through the slide column 423 to separate it from the coating platform 421, and then allow the cloth to pass through the coating platform 421, and then slide the discharge box 422 onto the coating platform 421 through the slide column 423, the bottom of the discharge box 422 presses the surface of the cloth, and then epoxy resin is put into the discharge box 422, and the epoxy resin flows to the coating through the through hole 427 at the bottom of the discharge box 422, which will facilitate the cloth to pass through the coating platform 421, and can also avoid the waste of epoxy resin, ensuring the cleanliness of the device.

[0043] Optionally, in some embodiments, see Figure 1 and Figure 2 In some embodiments, the coating assembly 42 further includes two guide rollers 424 , and gaps are provided on both sides of the coating platform 421 . The guide rollers 424 are rotatably connected to the coating platform 421 , and the guide rollers 424 are located on the gaps of the coating platform 421 , and a fabric channel is formed between the two guide rollers 424 .

[0044] With this arrangement, the cloth first passes through the cloth channel between the guide rollers 424 near one end of the spreading roller 2, and then passes through the cloth channel between the guide rollers 424 at the other end, which can ensure the flatness of the cloth and thereby reduce the probability of the cloth being folded when the receiving roller 3 recycles the cloth.

[0045] Optionally, see Figure 3 In some embodiments, the coating assembly 42 further includes a first scraper plate 425 and a second scraper plate 426, and the first scraper plate 425 and the second scraper plate 426 are both connected to the coating platform 421 by bolts, and the first scraper plate 425 and the second scraper plate 426 are both arranged along the height direction of the coating platform 421.

[0046] With such arrangement, after the cloth passes under the discharge box 422, the cloth passes between the first scraper plate 425 and the second scraper plate 426, the first scraper plate 425 scrapes off the excess epoxy resin on one side of the cloth, and the second scraper plate 426 scrapes off the excess epoxy resin on the other side of the cloth, thereby reducing the amount of epoxy resin carried on the cloth and reducing the probability of epoxy resin dripping onto the ground.

[0047] In some embodiments, see Figure 1 and Figure 2 In some embodiments, the drying component 43 includes a drying box 431, an electric heating plate 432, a temperature sensor 433 and a plurality of second transmission rollers 434. The drying box 431 is set on the frame 1 by bolts, the electric heating plate 432 is connected to the inner wall of the drying box 431 by bolts, the second transmission roller 434 is rotatably connected to the inside of the drying box 431, the temperature sensor 433 is set inside the drying box 431, and the temperature sensor 433 is connected to the electric heating plate 432 by electrical signals.

[0048] With such arrangement, the cloth enters the drying box 431 from the guide roller 424 near the coating assembly 42, passes through a plurality of second transmission rollers 434, and then comes out from the guide roller 424 near the receiving roller 3. Two electric heating plates 432 inside the drying box 431 face the surface of the cloth for drying. The temperature sensor 433 on the upper right is connected to the electric heating plate 432 by electrical signals. The temperature sensor 433 monitors the temperature of the electric heating plate 432 in real time. The plurality of second rotating rollers make the cloth stay in the drying box 431 for a long time to fully dry the cloth. The temperature sensor 433 ensures that the electric heating plate 432 will not be damaged due to excessively high or low temperature, so as to reduce the probability of damage to the cloth.

[0049] In some embodiments, see Figure 1In some embodiments, the drying component 43 further includes a hot air blower 435 and an air pipe 436. A long hole 437 is provided on the top of the drying box 431. The hot air blower 435 is connected to the frame 1 by bolts. A through hole 427 is provided on one side of the drying box 431. One end of the air pipe 436 is connected to the air outlet of the hot air blower 435, and the other end is connected to the drying box 431 through the through hole 427.

[0050] With such arrangement, hot air enters the drying box 431 from the air outlet of the hot air blower 435 through the air pipe 436 and the through hole 427 on the drying box 431, so that the interior of the drying box 431 maintains a dry environment. The hot air then flows out through the long holes 437 on the drying box 431, achieving the effect of air circulation.

[0051] Optionally, in some embodiments, see Figure 1 In some embodiments, a driving motor 5 is further provided on the frame 1, a pulley 6 is coaxially provided on the receiving roller 3, a belt 7 is transmission-connected to the pulley 6, and one end of the belt 7 away from the pulley 6 is transmission-connected to the output end of the driving motor 5.

[0052] With such arrangement, one end of the cloth is first wound around the receiving roller 3, and the driving motor 5 drives the belt 7 to rotate, thereby driving the receiving roller 3 to rotate, so that the entire cloth slides in the entire device, and the coated cloth is recovered at the same time.

[0053] The above description is only a preferred embodiment of the present application and is not intended to limit the present application. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present application should be included in the protection scope of the present application.
