Description

Technical Field

[0001] This application relates to the field of garment seam sealing technology, and in particular to a seam sealing device for flame-retardant and acid / alkali-resistant clothing. Background Technology

[0002] Flame-retardant and acid / alkali-resistant clothing is a type of functional protective clothing designed specifically for high-risk industries such as chemical, metallurgical, and electroplating. Its core function is to simultaneously resist flames, acid and alkali corrosion, and chemical penetration. The materials typically use base fabrics such as pure cotton, cotton-polyester blends, or cotton-nylon, processed through a combination of flame-retardant finishing and acid / alkali-resistant treatment. For example, the fabric may use a structure combining aramid fibers and cotton yarn. The outer flame-retardant layer does not decompose or melt at high temperatures, while the inner moisture-wicking layer achieves breathability and sweat-wicking through a cotton yarn structure.

[0003] The heat-sealing process is a key technology in the production of flame-retardant and acid / alkali-resistant clothing, and its functions include:

[0004] Sealing and protection: Hot melt adhesive film is bonded to the fabric through high-temperature hot pressing to form a continuous sealing layer, preventing acidic or alkaline liquids or chemical gases from penetrating through the seams. For example, the main adhesive fabric of chemical protective clothing is coated with flame-retardant and chemical-resistant adhesive on both sides, and the seam sealing is ensured through a bonding-sewing-tapping process.

[0005] Enhanced durability: Seam sealing reinforces easily worn areas such as garment seams and pocket openings, extending service life. The sealed area is flat and smooth, eliminating the raised feel of traditional seams and giving the garment a more professional appearance.

[0006] A search revealed Chinese Patent Publication No. CN220654854U, which discloses a sealing device for protective clothing. The device includes a lifting assembly, a sealing assembly, a tape fixing assembly, and a suction assembly. The lifting assembly includes a base plate with a support arm at its top. The support arm is bolted to the outer wall of the top of the base plate. An electric telescopic rod is bolted to the top of the support arm, and its bottom output end slidably passes through the support arm. The sealing assembly includes a first mounting frame bolted to the bottom of the electric telescopic rod's output end. The first mounting frame has two sets of protrusions arranged parallel to each other, each with a screw hole. A first connecting frame is located on the outer wall of the first mounting frame, with a groove at its top and screw holes on its outer wall. The groove and screw holes are adapted to the protrusions and screw holes of the first mounting frame. A drive motor is located on one side of the first connecting frame, and a transmission shaft is located on the other side of the drive motor.

[0007] Regarding the aforementioned related technologies, the inventors have discovered the following drawbacks:

[0008] During the tape pressing process, hot melt adhesive is prone to remain on the conveyor belt path, such as on the surface of the first and second rollers. Long-term accumulation can affect the flatness of the tape and even contaminate the fabric. Furthermore, the blower can adsorb harmful gases, but particles in the harmful gases may directly enter the blower and cause damage to it.

[0009] Therefore, in response to the above problems, the applicant provides a bonding device for flame-retardant and acid / alkali-resistant clothing. Utility Model Content

[0015] Optionally, as shown in Figures 1 and 2, a fixing plate is horizontally fixedly connected to the connecting beam, and a fan bottom bracket is bolted to the fixing plate. A suction pipe and an exhaust pipe are respectively flanged to the suction end and exhaust end of the fan, and a suction hood is threadedly connected to the suction pipe.

[0017] Optionally, a connecting frame is attached to the second support frame, and a screw is threaded onto the connecting frame and rotated onto the second support frame. One end of the connecting frame is fixedly connected to a frame.

[0018] Optionally, a closed plate is fixedly connected to the top of the frame, and a spring is fixedly connected to the closed plate.

Detailed Implementation

[0029] The following is in conjunction with the appendix Figure 1-5This application will be described in further detail.

[0030] This application discloses a bonding device for flame-retardant and acid / alkali-resistant clothing.

[0031] like Figure 1-5 As shown, a heat-sealing device for flame-retardant and acid-alkali resistant clothing includes a suction hood 5 and a sealing plate 15, wherein a filter screen 6 is threadedly connected to the suction hood 5.

[0032] The sealing plate 15 is provided with a scraping mechanism, which includes a spring 14. One end of the spring 14 is fixedly connected to a connecting frame 12, and the connecting frame 12 is fixedly connected to a silicone peeling strip 13.

[0033] Please see Figure 1 It also includes an operating platform 100, on the top of which a connecting beam 101 is fixedly connected. A support frame 1 is fixedly connected to the connecting beam 101. A first rotating roller 102 is rotatably connected to the support frame 1. A second support frame 2 is fixedly connected to the top of the operating platform 100. A second rotating roller 103 is rotatably connected to the support frame 2. The above structures are combined to form a glue pressing machine. Electrical components and specific structures not mentioned are existing technologies and will not be described in detail here.

[0034] Please see Figure 1 and Figure 2 A fixing plate 2 is horizontally fixedly connected to the connecting beam 101. The bottom bracket of the fan 3 is bolted to the fixing plate 2. The suction end and exhaust end of the fan 3 are respectively flanged and connected to the suction pipe 4 and the exhaust pipe 7. The suction pipe 4 is threadedly connected to the suction hood 5. The outer wall of the suction pipe 4 and the inner wall of the suction hood 5 are both engraved with threads. The two are connected by threads to facilitate the disassembly of the suction pipe 4 and the suction hood 5.

[0035] Please see Figure 1 and Figure 2 The bottom inner circumference of the suction hood 5 is engraved with internal threads, and the outer circumference of the filter screen 6 is engraved with external threads. The suction hood 5 is threadedly connected to the filter screen 6. The filter screen 6 is composed of acid and alkali resistant nylon mesh, molecular sieve filter mesh and PTFE microporous membrane from bottom to top. The fan 3 is connected to an external power source. When the fan 3 is turned on, the fan 3 draws the gas from the filter screen 6 into the suction pipe 4. At this time, the gas first passes through the acid and alkali resistant nylon mesh, which is mainly used to intercept large particles of glue residue. The molecular sieve filter mesh can adsorb and neutralize the acidic components in the irritating gas. The PTFE microporous membrane can capture micron-sized particles, thereby preventing secondary dust from fine glue particles or chemical crystals. Finally, the purified gas is discharged from the exhaust pipe 7. At the same time, by unscrewing the filter screen 6 from the suction hood 5, it is easy to clean the filter screen 6.

[0036] Please see Figure 3A connecting frame 8 is attached to the second support frame. A screw 9 is threaded onto the connecting frame 8 and rotated onto the second support frame. A frame 10 is fixedly connected to one end of the connecting frame 8. The screw 9 fixes the position of the frame 10 by rotating the connecting frame 8 and the second support frame in sequence. The connecting frame 8 and the frame 10 can be easily disassembled by unscrewing the screw 9. A scraping mechanism is also provided on the first support frame. Its connection method is the same as that on the second support frame, which will not be described in detail here.

[0037] Please see Figure 4 and Figure 5 A closed plate 15 is fixedly connected to the top of the frame 10, and a spring 14 is fixedly connected to the closed plate 15. The bottom surface of the connecting frame 12 is attached to the surface of the closed plate 15. Slider 11 is fixedly connected to both sides of the connecting frame 12. The two sliders 11 are slidably connected to the slide groove 1000. The slide groove 1000 is opened on the corresponding two sides of the frame 10. The function of the spring 14 is to rebound and drive the connecting frame 12 and the silicone peeling strip 13 to push the silicone peeling strip 13 to contact the second roller 103 and scrape off the residue on the surface of the second roller 103. The slider 11 slides in a straight line in the slide groove 1000, so that the silicone peeling strip 13 keeps moving in a straight line.

[0038] Please see Figure 4 and Figure 5 The frame 10 has two corresponding grooves 1001 on its two sides. A slider 17 is slidably connected in the groove 1001. An arc block 16 is fixedly connected to the slider 17. The arc block 16 is located below the silicone peel strip 13. A screw 18 is threaded onto the frame 10 and extends into the threaded hole of the arc block 16. The slider 17 is slid horizontally in the groove 1001 so that the arc block 16 is located about 0.2mm below the silicone peel strip 13. This is mainly to prevent the residue scraped by the silicone peel strip 13 from flowing out of the gap. At the same time, the residue slides down the arc surface of the arc block 16. The arc surface of the arc block 16 is made of silicone oil release agent to reduce the adhesion between the residue and the arc surface.

[0039] The implementation principle of the heat-sealing device for flame-retardant and acid / alkali-resistant clothing in this application embodiment is as follows:

[0040] When the blower 3 is turned on, the blower 3 draws the gas from the filter screen 6 into the suction duct 4. At this time, the gas first passes through the acid and alkali resistant nylon mesh, which is mainly used to intercept large particles of glue residue. The molecular sieve filter can adsorb and neutralize the acidic components in the irritating gas. The PTFE microporous membrane can capture micron-sized particles, thereby preventing secondary dust from fine glue particles or chemical crystals. Finally, the purified gas is discharged from the exhaust pipe 7.

[0041] The function of the spring 14 is to rebound and drive the connecting frame 12 and the silicone peeling strip 13 to push the silicone peeling strip 13 to contact the second roller 103 and scrape off the residue on the surface of the second roller 103. The residue after being scraped off by the silicone peeling strip 13 slides off the arc surface of the arc block 16.

[0042] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
