Description

Technical Field

[0001] This invention relates to the field of fabric finishing equipment technology, specifically to a three-proof finishing device for manufacturing flame-retardant fabrics. Background Technology

[0002] Fabric three-proof finishing devices generally refer to equipment or systems used to treat fabrics to be waterproof, oil-proof, and stain-proof (referred to as "three-proof"). These devices form a protective layer on the fabric surface through specific processes and technologies to achieve the three-proof effect.

[0003] However, traditional three-proof finishing devices require spraying the finishing agent onto the fabric surface first, and then drying it to form a protective film on the fabric surface. Traditional spraying methods often spray the entire fabric surface at the same time through a nozzle, which is inefficient and inconvenient for personnel to use. Summary of the Invention

The rotating shaft is located on the output end of the motor, and two rotating shafts located on the same side are detachably and coaxially pivotally connected to each other. The split arc panel is mounted on the rotating shaft. Multiple fabric grooves are formed on the split arc panel, and the fabric corresponds to each fabric groove. The rubber claws are located on the side of the split arc panel away from the rotating shaft.

[0009] Preferably, the split mechanism further includes a snap-fit ​​shaft seat and a secondary support rod. A slot is formed on the outer side of the split arc panel. One end of the secondary support rod is hinged to the slot, and the other end is detachably hinged to the snap-fit ​​shaft seat.

[0016] This invention provides a three-proof finishing device for manufacturing flame-retardant fabrics, such as... Figure 1-8 As shown, the system includes a base 1, a top rod 5, a main transverse slide 8, a split slide 9, a negative pressure suction mechanism 12, a housing 3, an adapter nozzle 27, a main slider 10, and a finishing liquid sprayer 11. The top rod 5 and housing 3 are both mounted on the base 1. The main transverse slide 8 is located on top of the top rod 5, and the split slide 9 is positioned along the width of the main transverse slide 8. The negative pressure suction mechanism 12 and the main slider 10 are slidably fitted onto the split slide 9, and the finishing liquid sprayer 11 is mounted on the main slider 10. The adapter nozzle 27 is located at the outlet of the finishing liquid sprayer 11 and is adapted to the top opening of the negative pressure suction mechanism 12. The split slide 9 communicates with the main transverse slide 8, and multiple parallel fabrics 6 are mounted on the negative pressure suction mechanism 12.

[0017] The negative pressure suction mechanism 12 includes two drive mechanisms 29 and four split mechanisms 30. The two drive mechanisms 29 are slidably engaged on the split slide rails 9. Each drive mechanism 29 includes an auxiliary slider 7, an auxiliary telescopic rod 4, a drive universal joint 14, and a drive turntable 19. The auxiliary slider 7 is slidably engaged on the split slide rails 9, and the auxiliary telescopic rod 4 is located at the bottom of the auxiliary slider 7. The drive universal joint 14 is located on the movable end of the auxiliary telescopic rod 4, and the drive turntable 19 is located on the movable end of the drive universal joint 14.

[0018] The drive mechanism 29 also includes a bracket 13 and two motors 20. The bracket 13 is located at the rotating end of the drive turntable 19, and the two motors 20 are symmetrically arranged on the bracket 13. The split mechanism 30 is linked to the motors 20, and multiple motors 20 correspond one-to-one with multiple split mechanisms 30.

[0019] The split mechanism 30 includes a split arc panel 16, a rotating shaft 21, and rubber claws 26. The rotating shaft 21 is located on the output end of the motor 20, and two rotating shafts 21 located on the same side are detachably and coaxially pivotally connected to each other. The split arc panel 16 is mounted on the rotating shaft 21. The split arc panel 16 has multiple fabric grooves 15, and the fabric 6 corresponds to the fabric grooves 15. The rubber claws 26 are located on the side of the split arc panel 16 away from the rotating shaft 21.

[0020] The split mechanism 30 also includes a snap-fit ​​shaft seat 23 and a secondary support rod 22. A slot 17 is provided on the outer side of the split arc panel 16. One end of the secondary support rod 22 is hinged to the slot 17, and the other end is detachably hinged to the snap-fit ​​shaft seat 23.

[0021] It also includes an electric telescopic rod 2, a bottom chuck 25, and two negative pressure suction pumps 28. The electric telescopic rod 2 is installed inside the housing 3, and the bottom chuck 25 is installed on the movable end of the electric telescopic rod 2. The two negative pressure suction pumps 28 are installed on the bottom chuck 25.

[0022] The split mechanism 30 also includes two top slides 18 and a stopper slider 24. The two top slides 18 are located at the top and bottom of the split arc panel 16, and the stopper slider 24 is slidably engaged with the inside of the top slides 18. The stopper slider 24 is adapted to the rubber claw angle 26.

[0023] The bottom chuck 25 and the adapter nozzle 27 are both adapted to the annular opening formed by the combination of four split arc panels 16 and the plug slider 24.

[0024] Working principle: When using, such as Figure 1 As shown, firstly, multiple fabrics 6 are passed through multiple fabric slots 15. At this time, four split arc panels 16 form a cylindrical structure. Then, the electric telescopic rod 2 is extended, forcing the bottom chuck 25 to hold the bottom of the four split arc panels 16 in place. At the same time, the bottom locking slider 24 of the split arc panels 16 is controlled to block the gap between the bottom chuck 25 and the four split arc panels 16 along the top slide rail 18. Simultaneously, the adapter nozzle 27 on the finishing liquid spraying machine 11 is lowered, and the electric telescopic rod 2 is extended, causing the bottom chuck 25 to move upward. At this time, most of the openings at the top and bottom of the cylindrical structure formed by the four split arc panels 16 are blocked. Then, the negative pressure suction pump 28 is controlled to quickly expel the air inside the four split arc panels 16. At this time, the finishing liquid sprayed by the adapter nozzle 27 quickly penetrates the multiple fabrics 6 under the action of negative pressure. At the same time, the used finishing liquid is discharged into the box 3.

[0025] After the finishing solution impregnation is completed, the auxiliary slider 7 moves away from each other along the split slide 9, and the drive turntable 19 drives the bracket 13 to rotate, so that the two split arc panels 16 are horizontally positioned in the housing 3. Then, the two motors 20 are rotated, so that the two split arc panels 16 can form a mechanical claw structure. At this time, by inserting the mechanical claw structure into the housing 3, the impurities in the used finishing solution in the housing 3 are initially removed through the cooperation between the drive universal seat 14 and the auxiliary telescopic rod 4, facilitating the recycling of the used finishing solution. At the same time, when cleaning the inside of the housing 3, the above working mode can agitate the cleaning solution in the housing 3, enhancing the cleaning effect on the inner wall of the housing 3. It can also clean the inner walls of the four split arc panels 16. This working mode, which eliminates the need for personnel to clean each panel individually, greatly reduces the cleaning workload.

[0026] In summary, this flame-retardant fabric manufacturing three-proof finishing device, through the coordinated arrangement of a base 1, a top rod 5, a main transverse slide 8, a split slide 9, a negative pressure absorption mechanism 12, a housing 3, an adapter nozzle 27, a main slider 10, and a finishing liquid spraying machine 11, allows the invention to utilize the principle of negative pressure to transform the originally open spray box into a sealed space, thereby enabling simultaneous agent penetration of multiple parallel fabrics 6, greatly facilitating user operation.
