Description

Technical Field

[0001] This invention relates to the field of spraying technology for flame-retardant composite fabrics, specifically to a processing device for antistatic and flame-retardant composite fabrics. Background Technology

[0002] In order to improve the performance of composite fabrics, existing technologies typically use a spraying method to apply a layer of antistatic and flame-retardant coating to the outer wall.

[0003] In actual production and processing, high-pressure spraying is usually used to fully coat the fabric. However, this method results in slow paint penetration and easy solidification, preventing the paint from penetrating well to the outer layer of the fabric. Since the fabric is woven from interlaced warp and weft threads, there are gaps between them. Due to the fabric's properties and strength, it is difficult to deform the fabric during the spraying and unwinding process, which leads to the gaps between the warp and weft threads being fully sealed. This makes it difficult for the sprayed paint to penetrate, causing it to clump and resulting in poor molding quality and easy peeling. Summary of the Invention

[0018] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0019] Please see Figures 1 to 6 The present invention provides a technical solution: An antistatic and flame-retardant composite fabric is provided, wherein the outer side of the composite fabric is coated with an antistatic and flame-retardant composite polymer coating, and the composite polymer coating penetrates into the gaps between the warp and weft threads of the fabric through a processing device.

[0020] A processing device for antistatic and flame-retardant composite fabric includes a spray box 1, an end cap 2 at the upper end of the spray box 1, an inner cavity 3 of the spray box 1, the composite fabric extending through the spray cavity 3, and telescopic pressure plates 25 for clamping the composite fabric symmetrically arranged on both sides of the end cap 2. Telescopic rods 24 are arranged on both sides of the lower end of the end cap 2, the telescopic rods 24 are located at the two ends of the spray cavity 3, and the pressure plates 25 are fixed to the telescopic ends of the telescopic rods 24. The composite fabric extends smoothly along the lower end surface of the pressure plate 25, and the lower end surface of the pressure plate 25 is rounded.

[0021] By setting the telescopic rod 24 to drive the pressure plate 25 to descend, the composite fabric located in the spray box 1 is clamped, thereby fixing and clamping the two ends of the composite fabric and limiting the height of the two ends of the composite fabric.

[0022] The end cap 2 is provided with a horizontally telescopic and sliding spray frame. The spray frame includes a horizontally sliding connecting block 26 and multiple sets of linearly distributed spray nozzles 9 located directly above the composite fabric. A pair of racks 7 are symmetrically arranged on both sides of the connecting block 26. A pair of symmetrically distributed gears 19 are provided at the upper end of the end cap 2. The gears 19 are driven by a motor. The pair of gears 19 are respectively meshed with the pair of racks 7. The length of the racks 7 is more than twice the width of the spray box 1.

[0023] The lateral position of the connecting block 26 is adjusted by the meshing of gear 19 and rack 7, thereby achieving the purpose of lateral drive.

[0024] A spraying rod 8 is provided between the upper end of the multiple spray nozzles 9 and the compression cavity 22. A pressure valve 10 is installed between the inner cavity of the spraying rod 8 and the compression cavity 22. A feed inlet 23 is provided on one side wall of the connecting block 26. One end of the feed inlet 23 is connected to the middle section of the compression cavity 22, and the other end of the feed inlet 23 is connected to the storage tank. An outer sliding groove 28 is provided through the middle of the end cover 2. An inner sliding groove 27 is symmetrically provided on the front and rear sides of the inner wall of the lower end face of the end cover 2. The two ends of the spraying rod 8 slide along the inner sliding groove 27, and the connecting block 26 is slidably installed on the outer sliding groove 28.

[0025] The position of the lateral drive is limited by setting the inner slide groove 27 and the outer slide groove 28, so as to ensure the smooth movement of the nozzle 9.

[0026] The inner cavity of the connecting block 26 is configured as a compression inner cavity 22. A pressure valve 10 is provided between the compression inner cavity 22 and the nozzle 9. One side of the compression inner cavity 22 is connected to a storage tank containing paint via a high-pressure pump. A telescopic piston rod assembly is provided at the upper end of the compression inner cavity 22. A support beam 4 is provided at the lower end of the composite fabric. Both ends of the support beam 4 pass through the end cap 2 and are connected to the piston rod assembly.

[0027] The high-pressure pump feeds material into the compression chamber 22, which in turn drives the piston rod assembly to rise and simultaneously lifts the support beam 4, thereby lifting a single position of the composite fabric to form an inclined state. At this time, due to the lifting of the support beam 4, the rising position of the fabric is stretched and pulled, which increases the gap between the warp and weft threads in the fabric, thus facilitating the full filling of the gap by the sprayed paint.

[0028] Working principle: First, motor-driven unwinding and rewinding frames are set on both sides of the spraying box 1. The composite fabric to be processed is placed on the unwinding frame, the middle section of the composite fabric passes through the spraying cavity 3, and the other end of the composite fabric is wound on the rewinding frame. Then, during spraying, the pressure plate 25 is used to clamp the composite fabric located at both ends of the spraying cavity 3 to achieve the purpose of limiting the height. Then, the high-pressure pump feeds, which increases the pressure inside the compression cavity 22, drives the piston rod assembly to lift the support beam 4, and stretches the fabric at the rising position, thereby increasing the gap between the warp and weft threads in the fabric. The pressure inside the compression cavity 22 reaches the preset value of the pressure valve 10, which in turn causes the paint to be sprayed out along the nozzle 9, thereby facilitating the full filling of the gaps by the sprayed paint and improving the penetration and forming efficiency of the paint on the fabric.

[0029] Example 2: Based on Example 1, in order to realize the linkage between the supporting beam 4 and the piston rod assembly, side blocks 15 are provided at both ends of the supporting beam 4. The upper end of the side block 15 passes through the end cover 2 and is fixedly connected to the piston rod assembly. The upper end of the compression cavity 22 is fixedly installed with a limit cover 20. The piston rod assembly includes a vertical rod 11 and a piston 12. The piston 12 slides up and down along the inner wall of the compression cavity 22. The lower end of the vertical rod 11 is fixed to the upper end face of the piston 12. The middle section of the vertical rod 11 slides through the limit cover 20. A lifting rod 13 is vertically provided at the upper end of the side block 15. The upper end of the lifting rod 13 is horizontally fixed on the crossbar 18. The middle of the crossbar 18 is fixedly sleeved on the vertical rod 11.

[0030] Through the cooperation of side block 15, lifting rod 13, crossbar 18, and upright rod 11, the support beam 4 and upright rod 11 are connected. Under the feeding pressure, the upright rod 11 rises, synchronously driving the support beam 4 to rise, thereby achieving the purpose of driving the fabric to deform. As the spray frame slides laterally, it drives the support beam 4 to slide along the lower end of the fabric, thereby driving the composite fabric to continuously deform as the support beam 4 slides, and the deformation position is always directly opposite the lower end of the nozzle 9.

[0031] The end cap 2 is provided with a through hole 14 corresponding to the lifting rod 13. The lifting rod 13 slides through the end cap 2 along the through hole 14. A spring 21 is vertically sleeved on the upright rod 11. The two ends of the spring 21 are pressed onto the piston 12 and the limiting cover 20, respectively.

[0032] By setting spring 21, the piston 12 is elastically squeezed and lifted. Then, after the spraying is completed and the feeding is stopped, the upright 11 and the support beam 4 are driven to descend and reset under the action of spring 21.

[0033] Example 3: Based on Example 2, in order to prevent the lower end of the fabric from being contaminated by the spray coating, a through groove 29 is provided in the middle of the supporting beam 4, and a multi-linearly distributed connecting rod 6 is provided in the middle of the through groove 29. The lower end of the spray coating cavity 3 is provided with a lower recovery groove 5 facing the through groove 29, and the upper end of the supporting beam 4 is provided with an arc-shaped outer wall.

[0034] By setting a through-channel groove 29 to receive the paint that penetrates along the gap between the warp and weft threads, the paint is prevented from adhering to the lower layer of the fabric. This, together with the lower recycling groove 5, enables the recycling of the through-channel paint.

[0035] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
