[0002] Fabric is a surface decoration material, which is often used on common items such as clothing, bags, shoes, etc. By adding a layer of fabric to the outside of the item for covering, the fabric can protect the inner layer from the influence of the external environment and play a role in protecting the inner material.

[0003] At present, the production of high-elasticity fire-retardant fabrics is carried out by coating the slurry on the base fabric layer and drying it.

This product is bound to be unqualified. At present, the generation of surface orange peel is reduced by appropriately increasing the machine speed and lowering the initial temperature of the drying furnace. However, the speed of each component of the production line is consistent. Due to the high viscosity of the mixed slurry, the higher speed has a certain impact on the slurry coating.

DETAILED DESCRIPTION

[0039] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0040] See also Figure 1-12 The embodiment of the present invention provides a high elastic fire retardant fabric preparation process, comprising a decorative layer, a base fabric layer 6 and a functional layer arranged in sequence, and further comprising:

[0041] S1, using a stirring device to mix a petroleum plasticizer, a UV stabilizer, a flame retardant, a vinyl powder, and a dye to obtain a mixed slurry A, and using a stirring device to mix a petroleum plasticizer, a UV stabilizer, a flame retardant, a vinyl powder, a dye, and a thickener to obtain a mixed slurry B;

[0042] S2, adding the mixed slurry A obtained in S1 into the coating component 1, using the material distribution component 2 to push the mixed slurry A to flow onto the coating component 1, the base fabric layer 6 is transported by the conveying roller 5, and when the base fabric layer 6 passes through the coating component 1, the mixed slurry A is evenly coated on one side of the base fabric layer 6 by the coating component 1 to form a decorative layer, thereby obtaining a cloth blank;

[0043] S3, drying the cloth blank obtained in S2;

[0044] S4, performing secondary coating on the dried cloth blank, coating the mixed slurry B obtained in S1 to the other side of the base cloth layer 6 to form a functional layer.

[0045] Under the condition of rapid transportation of the base fabric, the mixed slurry formed by mixing petroleum plasticizer, ultraviolet stabilizer, flame retardant, vinyl powder and dye has good fluidity, and the mixed slurry A is coated on the base fabric in conjunction with the coating component, so that the slurry can be evenly coated on the base fabric under the condition of rapid transportation, thereby improving the production quality of the cloth embryo and reducing the generation of orange peel. The petroleum plasticizer, ultraviolet stabilizer, flame retardant, vinyl powder, dye and thickener are mixed by using a stirring device to obtain a mixed slurry B. The mixed slurry B is coated on the other side of the base fabric layer 6 to form a functional layer. By increasing the use of the thickener, the viscosity is increased, so that the thickness of the functional layer can be in a thicker state during coating, which can significantly improve the fire retardant performance.

[0046] When the base fabric is conveyed quickly, higher requirements are put forward for the coating of the mixed slurry A. Therefore, we propose the following equipment to achieve uniform coating of the mixed slurry A under the condition of quickly conveying the base fabric layer 6;

[0047] A highly elastic fire-retardant fabric preparation device comprises: a conveying roller 5 for conveying a base fabric layer 6;

[0048] A coating assembly 1, the coating assembly 1 is arranged above the conveying roller 5, the base fabric layer 6 passes through the bottom of the coating assembly 1, the coating assembly 1 comprises a frame 100, a material guiding slope 101, and a material balancing groove 102, the material guiding slope 101 is arranged in the frame 100, the material balancing groove 102 is arranged on the upper part of the material guiding slope 101, the material balancing groove 102 has a first state and a second state, in the first state the material balancing groove 102 is used to hold the mixed slurry A, in the second state, the mixed slurry A in the material balancing groove 102 flows to the material guiding slope 101;

[0049] The material distribution component 2 is used to push the mixed slurry A to flow into the material distribution groove 102;

[0050] The air film 9 is arranged in the material guiding slope 101, and a variable cavity 91 is formed between the air film 9 and the coating component 1;

[0051] The movable component 7 is used to change the pressure in the variable cavity 91, so that the material balancing groove 102 can be switched back and forth between the first state and the second state through the change of pressure;

[0052] The linkage component 3, the conveying roller 5, the material distribution component 2 and the movable component 7 are connected through the linkage component 3.

[0053] The base fabric layer 6 is wound on the conveying roller 5, and when the conveying roller 5 rotates, the base fabric layer 6 can be driven to move;

[0054] The coating component 1 can coat the mixed slurry A on the base fabric layer 6 to form a decorative layer. The coating component 1 has a guide slope 101 which is inclined. The mixed slurry A flowing onto the guide slope 101 can flow and detach from the bottom of the guide slope 101. A material balancing groove 102 is provided on the upper part of the guide slope 101. The material balancing groove 102 is used to collect the mixed slurry A from the material balancing component 2. The mixed slurry A after stirring is transported to the silo 103 through a pipeline. The mixed slurry A in the silo 103 is pushed into the material balancing groove 102 through the material balancing component 2. The material balancing groove 102 is U-shaped. The material in the material balancing groove 102 can be temporarily stored in the material balancing groove 102, and the material in the material balancing groove 102 can be evenly distributed in the material balancing groove 102.

[0055] The air film 9, the material balancing groove 102, the frame 100 and the material guiding inclined surface 101 can enclose a variable cavity 91. The internal pressure of the variable cavity 91 can be changed under the pressure of the movable component 7 during the rotation of the conveying roller 5. When the air pressure is low, the material balancing groove 102 is as shown in the figure. Figure 4 As shown, a depression is formed, which can be used to store the mixed slurry A. When the air pressure increases, the material-mixing groove 102 will undergo a deformation, and its shape is as shown in the attached Figure 5 As shown, during the deformation of the material-uniform groove 102, the mixed slurry A inside it will enter the material guide slope 101. Since the mixed slurry A is evenly distributed in the material-uniform groove 102, after the mixed slurry A is separated from the material-uniform groove 102, it can be evenly distributed on the material guide slope 101. In this way, when the mixed slurry A is separated from the material guide slope 101, it coats the entire lower part of the material guide slope 101. Therefore, the mixed slurry A can be evenly contacted on the base fabric layer 6. In this way, during high-speed transportation, the uniform coating of the mixed slurry A can still be guaranteed.

[0056] In the embodiments of the present invention, please refer to Figure 1-3 A silo 103 is provided on the upper part of the frame 100, and the material distribution assembly 2 is arranged in the silo 103. The material distribution assembly 2 includes a positioning rod 20, a driving disc 21, a slider 22, a material pusher 23, a driving belt 24, and a shaft 25. The driving disc 21 is rotatably connected to the frame 100, a pair of driving discs 21 are connected by a driving belt 24, the shaft 25 is arranged on the driving belt 24, the positioning rod 20 is fixedly installed in the silo 103, the slider 22 is slidably connected to the positioning rod 20, a slide groove 221 is provided on the slider 22, and the lower end of the shaft 25 is rotatably connected in the slide groove 221.

[0057] The silo 103 is arranged on the top of the frame 100, and the mixed slurry A is transported into the silo 103 through a conduit, which is not shown in the attached drawings. The driving disc 21 can drive the driving belt 24 to rotate, and when the driving belt 24 rotates, the shaft 25 can be synchronously driven to move. The lower end of the shaft 25 is plugged into the slider 22, and when the shaft 25 moves, the slider 22 can be synchronously driven to move. When the slider 22 moves, the mixed slurry A in the silo 103 can be pushed to cooperate with the push The guidance of the material plate 23 allows the mixed slurry A to fall into the material equalizing groove 102. When the shaft rod 25 moves to the two ends of the driving disk 21, the shaft rod 25 can synchronously slide in the slide groove 221. In this way, after the direction of the shaft rod 25 is reversed, it is still inserted in the slider 22. After the direction of the shaft rod 25 is changed, the slider 22 can be synchronously driven to move in the opposite direction to achieve reciprocating displacement, thereby continuously pushing the mixed slurry A in the silo 103, so that the mixed slurry A can continuously fall into the material equalizing groove 102.

[0058] In the embodiments of the present invention, please refer to Figure 4-5The movable component 7 includes a first transmission shaft 4, a half gear 71, a rack 72, a pushing plate 73, a contact block 74, and a tension member 75. The pushing plate 73 is slidably connected to the lower part of the frame 100, the rack 72 is fixedly mounted on one side of the pushing plate 73, the contact block 74 is fixedly mounted on the upper part of the pushing plate 73, the first transmission shaft 4 is rotatably connected to the frame 100, the half gear 71 is fixedly mounted on the first transmission shaft 4, the half gear 71 and the rack 72 are meshed, and the tension member 75 is arranged in the frame 100. The tension member 75 applies a pulling force to the rack 72, so that the rack 72 has a tendency to move away from the air film 9.

[0059] The pushing plate 73 can only slide along the bottom surface of the frame 100, and the rack 72 is fixed on the pushing plate 73. Therefore, when the rack 72 moves laterally, the pushing plate 73 can be driven to move. During the counterclockwise rotation of the first transmission shaft 4, the half gear 71 will rotate counterclockwise synchronously. The half gear 71 and the rack 72 are meshed. Therefore, during the rotation of the half gear 71, the rack 72 will be subjected to thrust. Under the thrust, the rack 72 will overcome the tension provided by the tension member 75 to move, and the rack 72 will move in the direction of the air film 9. The displacement of the rack 72 will drive the pushing plate 73 to move, and the pushing plate 73 will cause the contact block 74 to move. The contact block 74 will squeeze the air film 9, and the air film 9 will be deformed after being squeezed. Figure 5 As shown, when squeezed, the pressure in the variable cavity 91 increases, and the material-distributing groove 102 will deform, so that the mixed slurry A in the material-distributing groove 102 will enter the material-guiding inclined surface 101, see the attached figure. Fig.12 In the embodiment, as the half gear 71 continues to rotate, the half gear 71 has a toothless section 711. When the toothless section 711 rotates, the rack 72 loses contact with the teeth. Under the pulling force of the tension member 75, the rack 72 will drive the contact block 74 to quickly reset. In this way, the pressure in the variable cavity 91 is reduced, and the material equalizing groove 102 is reset to the first state for containing the mixed slurry A. As mentioned above, the state switching of the material equalizing groove 102 is realized through the pressure change of the variable cavity 91. In this way, the material equalizing groove 102 can be evenly distributed on the material guide slope 101 during discharging. In this way, when the mixed slurry A falls along the material guide slope 101, the contact between the mixed slurry A and the base fabric layer 6 is also uniform. By evenly distributing the mixed slurry A on the base fabric layer 6, the coating quality of the mixed slurry A is guaranteed during rapid transportation.

[0060] In the embodiments of the present invention, please refer to Figure 1 , Figure 3The linkage assembly 3 includes a second transmission shaft 32, a bevel gear 33, a belt 34, and a chain 35. The second transmission shaft 32 is rotatably connected to the frame 100. A pair of bevel gears 33 are respectively installed on the driving disk 21 and the second transmission shaft 32. The first transmission shaft 4 and the second transmission shaft 32 are connected by a belt 34, and the first transmission shaft 4 and the conveying roller 5 are connected by a chain 35.

[0061] When the second transmission shaft 32 rotates, the second transmission shaft 32 rotates by utilizing the characteristics of a pair of bevel gears 33 meshing with each other, which can synchronously drive the driving disk 21 to rotate, so as to realize the smooth operation of the material distribution component 2, and the chain 35 cooperates with the sprocket to realize the transmission connection between the first transmission shaft 4 and the conveying roller 5. In this way, when the conveying roller 5 rotates, it synchronously drives the first transmission shaft 4 to rotate, and the first transmission shaft 4 and the second transmission shaft 32 are connected by a belt 34. In this way, during the rotation of the first transmission shaft 4, the second transmission shaft 32 can be synchronously driven to rotate. In this way, during the conveying process of the base cloth layer 6, the driving of the movable component 7 and the material distribution component 2 is completed.

[0062] In the embodiments of the present invention, please refer to Figure 6-12 , and also includes a material discharge assembly 8. During the process of the movable assembly 7 extruding the air film 9, the material discharge assembly 8 passively knocks the material guide slope 101, so that the mixed slurry A flows along the material guide slope 10. The material discharge assembly 8 includes a material discharge plate 81, a movable plate 82, a displacement frame 83, a torsion hinge 84, and a stopper 86. The material discharge plate 81 is hinged to the inner wall of the material guide slope 101 through the torsion hinge 84, the movable plate 82 is hinged to the material discharge plate 81, the stopper 86 is fixedly installed on the material discharge plate 81, and the displacement frame 83 is fixedly installed on the pushing plate 73. The movable plate 82 is arranged on the moving path of the displacement frame 83.

[0063] When the push plate 73 moves toward the air film 9, the contact block 74 squeezes the air film 9, and the pressure of the variable cavity 91 increases. At this time, the mixed slurry A in the material-balancing groove 102 flows to the material-guiding slope 101. Simultaneously, when the push plate 73 moves, the displacement frame 83 can be driven to move. When the displacement frame 83 moves toward the air film 9, the upper end of the displacement frame 83 will contact the movable plate 82. Figure 7 and Fig. 9 As shown, when the pushing plate 73 is displaced toward the air film 9, the displacement frame 83 abuts against the movable plate 82, so that the unloading plate 81 resists the torsion of the torsion hinge 84 and flips over, and the upper part of the unloading plate 81 will separate from the material guiding slope 101. As the pushing plate 73 continues to displace, the displacement frame 83 and the movable plate 82 are separated. Under the torsion of the torsion hinge 84, the unloading plate 81 is quickly reset and knocks on the material guiding slope 101. At this time, the mixed slurry A on the material guiding slope 101 will fall quickly. When resetting, as shown in the attached figure Figure 8and Fig.10 As shown, in order to ensure the rapid reset of the pushing plate 73, the movable plate 82 is not restricted by the block 86 in the counterclockwise direction. Therefore, when the displacement frame 83 is reset, the movable plate 82 will flip freely, and the movable plate 82 will only produce a small resistance to the displacement frame 83. Therefore, the displacement frame 83 can be quickly reset to avoid the rack 72 from colliding with the half gear 71 during the reset process, thereby protecting the rack 72 and the half gear 71.

[0064] The above description is only by way of illustration of certain exemplary embodiments of the present invention. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
