Description

Technical Field

[0001] This utility model relates to the field of fabric spraying technology, specifically to a multi-directional rotary electrostatic spraying device for waterproof outdoor fabrics. Background Technology

[0002] In related technologies, waterproof and breathable fabrics are widely used in outdoor clothing and apparel. These fabrics require both excellent waterproof performance and good breathability. For example, if a mountaineer wears a mountaineering garment made of waterproof and breathable fabric, the garment will not only protect them from wind and rain in inclement weather, but will also effectively wick away sweat, preventing it from accumulating on the skin and ensuring the dryness of the clothing and the mountaineer's comfort. Waterproofing fabrics can be achieved by applying a coating. Research has shown that graphite powder, when coated using electrostatic spraying, achieves excellent waterproof performance. Electrostatic spraying involves creating a high-voltage electrostatic field between the spray gun or spray disc and the workpiece. When the field is sufficiently high, the air near the nozzle undergoes corona discharge, ionizing the air. As paint particles pass through the nozzle, they become charged. Upon passing through the corona discharge zone, they further combine with the ionized air and become charged again. Under the influence of the high-voltage electrostatic field, they move towards the workpiece with opposite polarity and deposit on its surface. However, during electrostatic spraying, the paint can diffuse to the outside and be inhaled by workers, potentially harming their health.

[0003] To address the aforementioned technical issues, Chinese Patent No. CN115138493A discloses an electrostatic spraying device for waterproof coating of rain jacket fabric, comprising an electrostatic chamber, a filter assembly, and a winding assembly: a spray gun is installed inside the electrostatic chamber, the discharge end of the pump body is connected to the spray gun, an inlet is provided at one end of the electrostatic chamber, and an outlet is provided at the other end of the electrostatic chamber.

[0004] While the aforementioned existing technical solution prevents the air containing paint inside the electrostatic room from spreading to the outside through the inlet and outlet, its spray gun is directly fixed to the end of the connecting pipe, and the angle of the nozzle is fixed, making it impossible to adjust the spraying angle according to the actual size of the conveyed fabric, thus affecting the flexibility during actual spraying.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0022] Example: Please refer to Figures 1-4 This utility model provides a technical solution:

[0023] A multi-directional rotary electrostatic spraying device for waterproof outdoor fabrics includes a spraying machine body 1, a fixed cover 2 installed on one side of the spraying machine body 1, a material storage box 3 installed on the top of the fixed cover 2, a feed hopper embedded in the top of the material storage box 3, and a sealing cover locked to the top of the feed hopper. A multi-directional adjustment mechanism is installed on the nozzle 6 and the fixed cover 2. The multi-directional adjustment mechanism includes a front-to-back deflection component and a left-to-right deflection component. The front-to-back deflection component is used to adjust the front-to-back position of the nozzle 6, and the left-to-right deflection component is used to adjust the left-to-right position of the nozzle 6. During use, the front-to-back position of the nozzle 6 can be adjusted by the front-to-back deflection component, and the left-to-right position of the nozzle 6 can be adjusted by the left-to-right deflection component. The device has a simple structure and is easy to operate. Operators can flexibly adjust the spraying angle of the nozzle 6 according to the size of the fabric being processed, further ensuring the spraying effect.

[0024] In this embodiment, as Figure 1 , Figure 2 and Figure 3 As shown, a conveying pump 4 is embedded in one side of the outer wall of the storage tank 3. A corrugated pipe 5 extending to the inside of the fixed cover 2 is installed at the output end of the conveying pump 4. A nozzle 6 is installed at the bottom end of the corrugated pipe 5. First, the paint required for the waterproof outdoor fabric is added into the storage tank 3 through the feed hopper. Then, the conveying pump 4 is started. The conveying pump 4 extracts the paint from the storage tank 3 and conveys the paint to the nozzle 6 through the corrugated pipe 5, providing a paint source for the spraying operation.

[0025] In this embodiment, as Figure 1 , Figure 2 and Figure 3 As shown, the front and rear deflection assembly includes a fixed frame 7 installed at one end of the bottom of the fixed cover 2. A gear 8 is rotatably connected to one end of the inner side of the fixed frame 7. A gear ring 9 is meshed with one side of the gear 8. The gear ring 9 is slidably connected to the fixed frame 7. A first motor 10 is installed on one side of the outer wall of the fixed frame 7. The drive end of the first motor 10 extends to the inner side of the fixed frame 7 and is fixedly connected to one side of the gear 8. Then, when it is necessary to adjust the front and rear angle position of the nozzle 6, the first motor 10 is started. The drive end of the first motor 10 rotates, which drives the gear 8 fixedly connected to it to rotate. Since the gear 8 is meshed with the gear ring 9 and the gear ring 9 is slidably connected to the fixed frame 7, the rotation of the gear 8 will push the gear ring 9 to slide in the corresponding direction within the fixed frame 7. The movement of the gear ring 9 drives the linkage frame 11 to move back and forth through the connecting rod, thereby realizing the adjustment of the angle position of the nozzle 6 connected to the linkage frame 11 in the front and rear direction.

[0026] In this embodiment, as Figure 2 , Figure 3 and Figure 4As shown, the left and right deflection assembly includes a connecting rod installed at the bottom of the gear ring 9. A linkage frame 11 is installed at the bottom of the connecting rod. Sliding grooves 12 are provided at both ends of the linkage frame 11. Sliding blocks are slidably connected to the inner side of the sliding grooves 12. A first actuating plate 14 is rotatably connected to the top of the sliding block. A second actuating plate 15 is rotatably connected to the other end of the bottom of the first actuating plate 14. A vertical rod is installed at one top end of the linkage frame 11. A second motor 16 is installed at the top of the vertical rod. The drive end of the second motor 16 is connected to the second actuating plate 15. One end of the top is fixedly connected. Furthermore, when it is necessary to adjust the left and right angle position of the nozzle 6, one set of second motors 16 can be activated according to the required adjustment direction, while keeping the other set of second motors 16 and the third actuating plate 17 stationary. The driving end of the activated set of second motors 16 drives the second actuating plate 15 to rotate. When the second actuating plate 15 rotates, through its rotational connection with the first actuating plate 14, it drives the sliding block at the bottom of the first actuating plate 14 to slide in the sliding groove 12 while changing its angle.

[0027] In this embodiment, as Figure 2 , Figure 3 and Figure 4 As shown, a connecting frame is rotatably connected to the top end of the first actuating plate 14, and a third actuating plate 17 is rotatably connected to the inner side of the connecting frame. Limiting grooves are formed on both sides of the outer wall of the linkage frame 11. A limiting plate 18 is slidably connected to the inner side of the limiting groove. Both the limiting plate 18 and the limiting groove have T-shaped cross-sections. An extension rod 19 is installed at the other end of the limiting plate 18. One end of the extension rod 19 is rotatably connected to the other end of the third actuating plate 17, and the other end of the extension rod 19 is rotatably connected to a side plate 13. The other end of the side plate 13 is fixedly connected to one side of the nozzle 6. Furthermore, the connecting frame at the top of the first actuating plate 14 drives the third actuating plate 17 to rotate. When the third actuating plate 17 rotates, it pulls the limiting plate 18 to slide in the limiting groove through the extension rod 19. Since the limiting plate 18 is rotatably connected to the side plate 13, and the side plate 13 is fixedly connected to the nozzle 6, when the limiting plate 18 slides in the limiting groove, it drives the nozzle 6 connected to it to deflect at an angle. The T-shaped cross-section design of the limiting plate 18 and the limiting groove can effectively prevent the limiting plate 18 from coming out of the limiting groove and ensure the stability of the left and right position adjustment process.

[0028] The implementation principle of the multi-directional rotary electrostatic spraying device for waterproof outdoor fabrics in this embodiment is as follows: The required coating for the waterproof outdoor fabric is added to the storage tank 3 through the feed hopper. The delivery pump 4 is started, and the delivery pump 4 extracts the coating from the storage tank 3 and delivers it to the spray head 6 through the corrugated pipe 5, providing a coating source for the spraying operation. When it is necessary to adjust the front-to-back angle position of the spray head 6, the first motor 10 is started. The drive end of the first motor 10 rotates, driving the gear 8 fixedly connected to it to rotate. Since the gear 8 is meshed with the gear ring 9, and the gear ring 9 is slidably connected to the fixed frame 7, the rotation of the gear 8 will push the gear ring 9 to slide in the corresponding direction within the fixed frame 7. The movement of the gear ring 9 drives the linkage frame 11 to move back and forth through the connecting rod, thereby realizing the adjustment of the angle position of the spray head 6 connected to the linkage frame 11 in the front-to-back direction. When it is necessary to adjust the left-to-right angle position of the spray head 6, the device can be started according to the required adjustment direction. One set of second motors 16 is activated, while the other set of second motors 16 and the third actuating plate 17 remain stationary. The driving end of the activated second motor 16 drives the second actuating plate 15 to rotate. When the second actuating plate 15 rotates, through its rotational connection with the first actuating plate 14, it causes the sliding block at the bottom of the first actuating plate 14 to slide within the sliding groove 12 while changing its angle. The connecting frame at the top of the first actuating plate 14 drives the third actuating plate 17 to rotate. When the third actuating plate 17 rotates, it pulls the limiting plate 18 to slide within the limiting groove through the extension rod 19. Since the limiting plate 18 is rotatably connected to the side plate 13, and the side plate 13 is fixedly connected to the nozzle 6, when the limiting plate 18 slides within the limiting groove, it causes the nozzle 6 connected to it to deflect at an angle. The T-shaped cross-section design of the limiting plate 18 and the limiting groove can effectively prevent the limiting plate 18 from coming out of the limiting groove, ensuring the stability of the left and right position adjustment process.

The power supply is also common knowledge in the field. Since this utility model is used to protect mechanical devices, the control method and circuit connection will not be explained in detail.
