Description

Technical Field

[0001] The utility model relates to the field of polyester fabric production, in particular to a polyester fabric flame retardant finishing device. Background Art

[0002] Polyester fabrics are popular in the market due to their wide range of applications and excellent physical properties. However, they are also flammable. Therefore, in certain applications, such as interior decoration, automotive interiors, and airline seats, polyester fabrics require flame-retardant finishing to improve their safety. Flame-retardant finishing of polyester fabrics typically involves the following steps: padding, drying, hot melt, soaping, washing, and drying. This process is achieved using specialized finishing equipment to ensure that the fabric achieves the desired flame retardant effect. When the fabric is pulled out after padding, a large amount of finishing liquid adheres to the surface. As workers remove the fabric and transfer it to the dryer for drying, excess finishing liquid drips from the fabric to the floor, requiring cleanup and increasing the workload.

[0003] Therefore, in order to solve the deficiencies in the prior art, a flame retardant finishing device for polyester fabrics with a simple structure needs to be designed. Utility Model Content

[0019] Below with reference to the embodiment and the attached Figures 1 to 4 , the technical solution of the utility model is further elaborated.

[0020] Example 1

[0021] A flame retardant finishing device for polyester fabrics, comprising: a box body 1, fixed rollers 2, lifting rollers 3, a crossbar 31, a drive mechanism 4, a lifting and pressing roller 51, a fixed pressing roller 52, a bevel mesh plate 6, a water pusher 7, a transverse elastic telescopic rod 81, and a vertical telescopic rod 82. The fixed rollers 2 are arranged at intervals in the box body 1, the lifting rollers 3 are arranged at intervals between the fixed rollers 2, the lifting rollers 3 are connected to the crossbar 32 via a connecting frame 1 32, the crossbar 31 is arranged on the drive mechanism 4 and is lifted and lowered by the drive mechanism 4, and the lifting and pressing rollers 51 are connected to the crossbar 31 via a connecting frame 2 53. The fixed pressure roller 52 is located on the right side of the rightmost fixed roller 2, and the fixed pressure roller 52 is located directly below the lifting pressure roller 51. The left end of the transverse elastic telescopic rod 81 is connected to the connecting frame 2 53, and the left side of the water pushing plate 7 is connected to the right side of the transverse elastic telescopic rod 81. The upper end of the vertical telescopic rod 82 is connected to the frame 9, and the lower end of the vertical telescopic rod 82 is connected to the transverse elastic telescopic rod 81. The water pushing plate 7 is fitted with the inclined mesh plate 6, and inclined wingspans 71 are provided on both sides of the water pushing plate 7. The connecting frame 2 53 is provided with a pushing block 54 for pushing the transverse elastic telescopic rod 81.

[0022] like Figures 1 to 4 As shown, the working principle of the present invention is as follows: first, the driving mechanism 4 controls the lifting roller 3 to be located above the fixed roller 2, and the polyester fabric passes between the lifting roller 3 and the fixed roller 2 to the right. Then, the driving mechanism 4 controls the lifting roller 3 to descend, and the fabric is changed from a straight shape to an S shape and enters the flame retardant finishing liquid, thereby increasing the fabric padding time. The fixed pressing roller 52 is located above the liquid surface, and at the same time, the driving mechanism 4 moves downward to drive the lifting and pressing roller 51 to move downward synchronously until it cooperates with the fixed pressing roller 52, and the excess finishing liquid is squeezed back into the finishing liquid, and the connecting frame 53 is lowered. The movement causes the pushing block 54 to push the transverse elastic telescopic rod 81, the vertical telescopic rod 82 and the water pushing plate 7 downward, and the water pushing plate 7 contacts the inclined mesh plate 6. During the downward movement of the water pushing block 7, the internal spring of the transverse elastic telescopic rod 81 is squeezed, and the water pushing plate 7 is in close contact with the inclined mesh plate 6 through the spring thrust. The fabric that has been squeezed out of water once is squeezed again through the water pushing plate 7, and the finishing liquid above the fabric flows out along the inclined wingspans 71 on both sides and falls into the box body 1, and the finishing liquid below the fabric falls into the box body 1 through the through holes of the inclined mesh plate 6.

[0023] The downward movement distance of the lifting and lowering pressure roller 51 is controlled to adjust the pressure of the primary extrusion. The different downward movement distances of the lifting and lowering pressure roller 51 can synchronously control the positions of the horizontal elastic telescopic rod 81, the vertical telescopic rod 82 and the water pushing plate 7, and then synchronously adjust the secondary extrusion pressure achieved by the water pushing plate 7 in conjunction with the inclined mesh plate 6. The structure is simple, removes excess finishing liquid from the fabric, prevents excess finishing liquid from falling, and reduces the workload of the staff.

The motor 42 and the screw 43 drive the ball nut pair 44 and the cross bar 31 to move up and down.
