Description

Technical Field

[0001] This utility model relates to the field of fiber fabric technology, and in particular to a coating device for fabrics. Background Technology

[0002] Carbon fiber, as an advanced composite material, has been widely used in aerospace, nuclear energy equipment, transportation, and many other fields. In certain applications, it is often necessary to sprinkle resin or other powders onto the surface of carbon fiber fabrics to enhance their properties.

[0003] Existing powder spreading machines are expensive to purchase, have complex structures, and even have problems with uneven powder spreading weight control, which is not conducive to their use in actual production. Utility Model Content

[0004] To address the aforementioned issues, this application provides a reasonably structured coating device for fabrics, which uses a powder-spreading roller combined with a vibrating screen to evenly spread powder onto the fabric. The overall structure is simplified and compact, effectively reducing equipment costs while ensuring uniform powder spreading, and facilitating practical production use.

[0005] The technical solution adopted in this utility model is as follows: A coating apparatus for fabrics includes a frame, a feeding trough installed inside the frame, a powder-spreading roller mounted on the frame at the bottom of the feeding trough, an elongated groove along the length of the powder-spreading roller at the bottom of the feeding trough, and the powder-spreading roller disposed in the elongated groove; brush rollers arranged side by side on the sides of the powder-spreading roller are also installed inside the frame, and a vibrating screen is installed inside the frame below the powder-spreading roller and the brush roller, with the fabric located below the vibrating screen.

[0006] As a further improvement to the above technical solution: The outer walls of the feeding troughs on both sides of the long trough are respectively equipped with scrapers, and a gap smaller than the diameter of the powder is formed between the scrapers and the outer wall of the powder spreading roller.

[0007] The brush roller is located on the feed side relative to the powder-spreading roller, and a receiving tray is installed below the powder-spreading roller towards the discharge side.

[0008] Guide rollers are installed on the feed side and discharge side of the frame, respectively. The guide rollers are located below the vibrating screen and are spaced apart in the vertical direction. The fabric passes through the gap from the feed side and exits from the discharge side.

[0009] The structure of the vibrating screen is as follows: it includes a support ring mounted on the frame, a ring-shaped screen base supported by an elastic element above the support ring, and a screen is arranged inside the screen base; a vibrator is also installed on the screen base.

[0010] The feeding trough includes side plates arranged at relatively intervals. The distance between the opposing walls of the side plates is larger at the top and smaller at the bottom, forming an opening at the top and a long trough at the bottom. The ends of the side plates are all equipped with end plates. A fixing plate is also installed between the side plates located inside the end plates at both ends. A distance is provided between the bottom surface of the fixing plate and the inner wall surface of the side plate.

[0011] An amplitude adjustment plate is installed on the inner side of the side plate located between the end plate and the fixed plate. The amplitude adjustment plate is driven by the amplitude adjustment mechanism to move toward or away from the end plate. The edge of the amplitude adjustment plate is covered with an adhesive strip, which is attached to the inner wall of the side plate.

[0012] The amplitude adjustment mechanism has the following structure: it includes a screw that is rotatably installed between the end plate and the fixed plate, with a handwheel installed at the end of the screw extending out of the end plate, and an amplitude adjustment plate threadedly fitted onto the screw; it also includes a guide rod installed between the end plate and the fixed plate, with the amplitude adjustment plate slidably fitted onto the guide rod.

[0013] The frame located at both ends of the brush roller has long strip-shaped adjustment grooves. The supports at both ends of the brush roller move along the adjustment grooves to adjust the distance between the brush roller and the powder-spreading roller. The supports are locked relative to the adjustment grooves by fasteners.

[0014] A recycling hopper is installed inside the frame located below the fabric; a level gauge is installed at the bottom of the feeding trough.

[0015] Compared with the prior art, the present invention has the following beneficial effects: When this utility model is in use, the powder flows downward from the feeding trough along the powder-spreading roller, and the brush roller causes the powder to fall from the powder-spreading roller to the vibrating screen, and finally fall onto the fabric through the vibrating screen. Thus, the powder is evenly spread on the fabric by the powder-spreading roller and the vibrating screen. The overall structure is simplified and compact, which effectively reduces equipment costs while ensuring even powder spreading and is convenient for actual production use. This utility model also has the following advantages: The scrapers on both sides of the long groove of the feeding trough can limit and block the falling of powder by setting the gap, and at the same time, the scrapers will not come into contact with the powder spreading roller, effectively avoiding scraper wear. By setting a receiving tray on the discharge side below the powder-spreading roller, the powder falling can be caught by the receiving tray, preventing the powder falling from the discharge side of the powder-spreading roller onto the fabric surface and affecting the powder-spreading accuracy. By setting the amplitude adjustment plates at both ends of the inner side of the feeding trough, combined with the amplitude adjustment mechanism, the actual powder spreading width can be adjusted to match the actual coating needs and improve the flexibility of actual use.

[0024] The specific embodiments of this utility model are described below with reference to the accompanying drawings.

[0025] like Figure 1 , Figure 2 and Figure 3 As shown, a coating device for fabric in this embodiment includes a frame 1, a feeding trough 5 installed inside the frame 1, a powder-spreading roller 7 installed on the frame 1 at the bottom of the feeding trough 5, a long groove is opened at the bottom of the feeding trough 5 along the length of the powder-spreading roller 7, and the powder-spreading roller 7 is disposed in the long groove; a brush roller 3 arranged side by side on the side of the powder-spreading roller 7 is also installed inside the frame 1, and a vibrating screen 9 is installed inside the frame 1 below the powder-spreading roller 7 and the brush roller 3, and the fabric 10 is located below the vibrating screen 9.

[0026] In this embodiment, the powder-spreading roller 7 located at the bottom of the feeding trough 5 carries the powder out of the feeding trough 5 in an orderly and controlled manner. Combined with the vibration and sieving of the vibrating screen 9, the uniformity of powder coating is effectively achieved and guaranteed.

[0027] In use, the powder flows downward from the powder-spreading roller 7 out of the feeding trough 5, and the brush roller 3 causes the powder to fall from the powder-spreading roller 7 to the vibrating screen 9, and finally fall onto the fabric 10 through the vibrating screen 9. Thus, the powder-spreading roller 7 combined with the vibrating screen 9 achieves the goal of evenly spreading the powder on the fabric 10.

[0028] like Figure 4 As shown, scrapers 50 are respectively installed on the outer walls of the feeding troughs 5 on both sides of the long trough, and a gap smaller than the diameter of the powder is formed between the scrapers 50 and the outer wall of the powder spreading roller 7.

[0029] In this embodiment, the scrapers 50 on both sides of the long groove of the feeding trough 5 can limit and block the falling of powder by setting the gap, and at the same time, the scrapers 50 will not come into contact with the powder spreading roller 7, effectively avoiding wear of the scrapers 50.

[0030] In this embodiment, the gap between the scraper 50 and the powder spreading roller 7 can be set to effectively match the thickness and uniformity requirements of the powder falling and being spread.

[0031] In this embodiment, the scraper 50 can be configured as a fixed or detachable structure relative to the feeding trough 5, depending on actual usage requirements.

[0032] In this embodiment, the scraper 50 can be made of alloy material.

[0033] The brush roller 3 is located on the feed side relative to the powder-spreading roller 7, and a receiving tray 8 is installed below the powder-spreading roller 7 towards the discharge side.

[0034] In this embodiment, the powder on the powder-spraying roller 7 is brushed off the side by the brush roller 3, and the falling powder can be caught by the receiving tray 8 on the other side. This prevents the powder falling from the discharge side of the powder-spraying roller 7 from falling onto the surface of the fabric 10 for secondary coating, which would affect the powder-spraying accuracy and help ensure the uniformity of the powder coating.

[0035] Guide rollers 2 are installed on the feed side and discharge side of the frame 1, respectively. The guide rollers 2 are located below the vibrating screen 9 and form a gap in the vertical direction. The fabric 10 passes through the gap from the feed side and exits from the discharge side.

[0036] In this embodiment, the guide roller 2 provides support for the fabric 10 as it enters and exits the coating device, ensuring the stability and reliability of the fabric 10's transport and contributing to the coating effect.

[0037] like Figure 5 As shown, the structure of the vibrating screen 9 is as follows: it includes a support ring 91 mounted on the frame 1, and a ring-shaped screen base 93 supported by an elastic element 92 above the support ring 91. A screen 94 is arranged inside the screen base 93. A vibrator 95 is also installed on the screen base 93.

[0038] In this embodiment, the vibrator 95 drives the mesh holder 93 and the screen 94 to vibrate, thereby causing the powder to pass through the screen 94 in an orderly manner and fall onto the fabric 10.

[0039] In this embodiment, the support ring 91 can be installed with the frame 1 to form a structural support for the installation of the screen 94; the elastic element 92 can be selected as a spring according to the usage requirements.

[0040] In this embodiment, the material of the 94 mesh can be selected according to actual needs, such as stainless steel wire.

[0041] The feeding trough 5 includes side plates 53 arranged at relatively intervals. The distance between the opposing walls of the side plates 53 is larger at the top and smaller at the bottom, forming an opening at the top and a long trough at the bottom. The ends of the side plates 53 are all equipped with end plates 51. A fixing plate 52 is also installed between the side plates 53 located inside the end plates 51 at both ends. A distance is provided between the bottom surface of the fixing plate 52 and the inner wall surface of the side plate 53.

[0042] In this embodiment, the setting of the fixing plate 52 effectively ensures the structural strength of the feeding trough 5, prevents its deformation, and does not affect the smooth falling of the powder in the feeding trough 5.

[0043] An amplitude adjustment plate 40 is installed on the inner side of the side plate 53 located between the end plate 51 and the fixed plate 52. The amplitude adjustment plate 40 is driven by the amplitude adjustment mechanism 4 to move toward or away from the end plate 51. The edge of the amplitude adjustment plate 40 is covered with a rubber strip 401, which adheres to the inner wall of the side plate 53 to effectively prevent powder leakage.

[0044] In this embodiment, by setting the amplitude adjustment plates 40 at both ends of the inner side of the feeding trough 5, combined with the amplitude adjustment mechanism 4, the actual powder spreading width is adjusted to match the actual coating requirements and improve the flexibility of actual use.

[0045] In this embodiment, depending on actual usage requirements, openable and closable discharge ports can be provided at both ends of the feeding trough 5, such as at the lower part of the end plate 51 and the amplitude adjustment plate 40, so as to facilitate cleaning the remaining powder inside the feeding trough 5.

[0046] like Figure 6 As shown, the structure of the amplitude adjustment mechanism 4 is as follows: it includes a screw 42 rotatably mounted between the end plate 51 and the fixed plate 52, the end of the screw 42 extends out of the end plate 51 and is equipped with a handwheel 41, and the amplitude adjustment plate 40 is threadedly fitted to the screw 42; it also includes a guide rod 43 mounted between the end plate 51 and the fixed plate 52, and the amplitude adjustment plate 40 is slidably mounted on the guide rod 43.

[0047] In this embodiment, when the width needs to be adjusted, force is applied to the handwheel 41 to drive the screw 42 to rotate. The amplitude adjustment plate 40, which is screwed to the screw 42, will move along its length direction guided by the guide rod 43, approaching or moving away from the end plate 51.

[0048] like Figure 7 As shown, a long strip-shaped adjustment groove 30 is provided on the frame 1 located at both ends of the brush roller 3. The supports at both ends of the brush roller 3 move along the adjustment groove 30 to adjust the distance between the brush roller 3 and the powder-spreading roller 7. The supports are locked relative to the adjustment groove 30 by fasteners.

[0049] In this embodiment, the distance between the brush roller 3 and the powder-spreading roller 7 can be adjusted by opening the adjustment groove 30, so as to conveniently match different powder coating requirements and improve the flexibility of use.

[0050] In this embodiment, the brush roller 3 can be made of carbon steel roller with nylon bristles covering the surface, which is wear-resistant and does not easily shed bristles.

[0051] A recycling hopper 12 is installed inside the frame 1 located below the fabric 10 for recycling scattered powder.

[0052] In this embodiment, the bottom surface of the recycling hopper 12 can be configured as a sloping structure facing one end, and a discharge port is provided at the bottom of the sloping structure for easy cleaning.

[0053] A level gauge 6 is installed at the bottom of the feeding trough 5. When the material level is too low, an alarm will be triggered to remind the user to add material.

[0054] In this embodiment, the level gauge 6 can be a commonly used standard component, such as a rotary paddle level switch, which can detect the level of material in the feeding trough 5.

[0055] In this embodiment, the brush roller 3 and the powder-spreading roller 7 can both be driven to rotate by the motor 71 via the transmission component 72, that is, they can rotate simultaneously by the same power combined with gear transmission, or the brush roller 3 and the powder-spreading roller 7 can be driven to rotate by their respective motors 71 via the transmission component 72, and their rotation can be controlled independently.

[0056] In this embodiment, side sealing plates 11 can be installed on the feed side and the discharge side of the frame 1 respectively, so as to create a conveying space for the fabric 10 to enter and exit. At the same time, end sealing plates 13 can be installed on the other opposite ends of the frame 1 to reduce or even avoid interference with the internal powder coating.

[0057] This invention combines a powder-spreading roller with a vibrating screen to evenly spread powder onto fabric. The overall structure is simplified and compact, effectively reducing equipment costs while ensuring uniform powder spreading and facilitating practical production.

[0058] The various embodiments in this specification are described in a progressive manner, with each embodiment focusing on the differences from other embodiments. The same or similar parts between the various embodiments can be referred to each other.

[0059] The above description is an explanation of the present utility model and not a limitation thereof. The scope of the present utility model is defined by the claims. Within the protection scope of the present utility model, any form of modification may be made.
