Technical Field

[0001] The utility model relates to the technical field of mechanical equipment, in particular to a coating machine for flame-retardant fabrics. Background Art

[0002] Coating machines are mainly used for surface coating production of films, fabrics, etc. Coating machines evenly coat flame retardants on the surface of fabrics to provide fire resistance and protection.

[0003] The Chinese patent "Low Energy Consumption Micro-Discharge Coating Machine" authorization announcement number "CN216891524U" uses a vacuum pump to absorb the hot air generated in the drying section and transport it to the water storage part, so that the water in the water storage part flows into the spray head and is sprayed onto the surface of the fabric in a mist manner, and then the second bottom plate and the second top plate are used to realize the humidification and smoothing process of the fabric passing through, ensuring the coating effect of the coating machine on the fabric.

[0004] The hot air generated in the drying section is transported to the water storage part. As the hot air dries the coated fabric, it will come into contact with the volatile substances on the fabric, causing the harmful substances in the gas to dissolve in the water. The water may contain harmful substances, and then the water is sprayed onto the fabric, which may affect the texture and performance of the fabric, thereby affecting the coating effect of the coating machine on the fabric.

[0005] Therefore, a coating machine for flame retardant fabrics is proposed to solve the above problems. Utility Model Content

When it is necessary to dehumidify and flatten the wet fabric, the air extraction pump extracts the hot air in the drying chamber and transports it to the two heating frames through the air pipe 3 and the conveying pipe respectively. When the hot air in the heating frame is flowing, after flowing a certain distance, the hot air passes through the purification exhaust pipe, is purified and then discharged, heating the surface of the heating frame, and the heating frame contacts the moving wet fabric to dehumidify and flatten the wet fabric.

[0024] As Figures 2-4As shown in the figure, the driving assembly 505 includes a reciprocating lead screw 5051 slidably connected to the inner wall of the push rod 502. One end of the reciprocating lead screw 5051 is fixedly connected to a pulley 5052. The number of pulleys 5052 is two. A belt 5053 is drivingly connected to the surfaces of the two pulleys 5052.

The front end of the feeding frame 1 is fixedly connected to a connecting frame 50512. One end of one of the pulleys 5052 is rotatably connected to the inner wall of the connecting frame 50512. (The reciprocating lead screw 5051 is a lead screw that can make the push rod 502 perform reciprocating motion without changing the rotation direction of the main shaft. The reciprocating lead screw 5051 is in the form of two thread grooves with the same pitch and opposite helix directions, and the two ends are connected by a transition curve. Through the rotation of the lead screw, the side of the helical groove pushes the push rod 502 placed in the helical groove to perform axial reciprocating motion.)

[0025] When it is necessary to wet the moving fabric, the hot air in the air pipe 3 pushes the wind wheel 5055 to rotate during circulation. The rotation of the wind wheel 5055 drives the corresponding pulley 5052 to rotate. The corresponding pulley 5052 drives the other pulley 5052 to rotate through the belt 5053. The rotation of the other pulley 5052 drives the reciprocating lead screw 5051 to rotate. The rotation of the reciprocating lead screw 5051 drives the push rod 502 to reciprocate in the water tank 4. The movement of the push rod 502 drives the piston block 501 to reciprocate in the water tank 4. During the reciprocating movement of the piston block 501 in the water tank 4, the water in the water tank 4 is pushed through the circulation pipe 503 and respectively delivered to the two spray pipes 504. The water in the spray pipes 504 starts to spray water on the moving fabric, preventing the hot air from directly entering the water tank 4 and pushing the water to be delivered to the spray pipes 504. Furthermore, it prevents harmful substances in the gas from dissolving in the water, ensuring that the water sprayed on the fabric will not affect the texture and performance of the fabric, and guaranteeing the effect of the coating machine applying the flame retardant to the fabric.

The filter screen 50511 filters the water flowing into the collection box 5059, blocking impurities in the water from entering the collection box 5059, ensuring the cleanliness of the water inside the collection box 5059. The collection box 5059 is used to collect the sprayed water. After the water in the collection box 5059 accumulates to a certain amount, it is pumped into the water tank 4 through the water pump 50510, facilitating the recycling of water and reducing the waste of water resources.

[0027] When the present utility model is in use, when it is necessary to wet the moving fabric, the hot air in the air pipe 3 drives the wind wheel 5055 to rotate during circulation. The rotation of the wind wheel 5055 drives the corresponding belt pulley 5052 to rotate. The corresponding belt pulley 5052 drives another belt pulley 5052 to rotate through the belt 5053. The rotation of the other belt pulley 5052 drives the reciprocating lead screw 5051 to rotate. The rotation of the reciprocating lead screw 5051 drives the push rod 502 to reciprocate in the water tank 4. The movement of the push rod 502 drives the piston block 501 to reciprocate in the water tank 4. During the reciprocating movement of the piston block 501 in the water tank 4, the water in the water tank 4 is pushed through the circulation pipe 503 and respectively delivered to the two spray pipes 504. The water in the spray pipes 504 starts to spray water on the moving fabric, preventing the hot air from directly entering the water tank 4 and pushing the water into the spray pipes 504, thereby preventing harmful substances in the gas from dissolving in the water and ensuring that the water sprayed on the fabric does not affect the texture and performance of the fabric, and ensuring the effect of the coating machine applying the flame retardant to the fabric.
