Description

Technical Field

[0001] This utility model belongs to the field of mesh fabric production and relates to a coating device for mesh fabric production. Background Technology

[0002] Mesh fabric is widely used in many industries due to its lightweight, breathable, and high-strength characteristics. With the continuous development of the functional textile market, users have put forward higher performance requirements for mesh fabric.

[0003] While traditional mesh fabrics possess good breathability and mechanical strength, ordinary mesh fabrics are prone to absorbing and permeating water, limiting their use in humid or waterproof environments. Typically, an anti-permeability coating needs to be applied to the surface of the mesh fabric to enhance its anti-permeability performance. However, the anti-permeability coatings formed by existing coating devices are often highly sealed, which can affect the breathability and heat dissipation performance of the mesh fabric itself. Utility Model Content

[0004] The purpose of this invention is to address the aforementioned problems in the existing technology by providing a coating device for producing mesh fabric that can maintain the breathability of the mesh fabric.

[0005] The objective of this utility model can be achieved through the following technical solutions:

[0006] A coating apparatus for producing mesh fabric includes a frame, characterized in that, from left to right, a feeding conveyor mechanism, a coating mechanism, a drying mechanism, a piercing mechanism, and a discharging conveyor mechanism are sequentially arranged on the frame. The feeding and discharging conveyors are capable of pulling and conveying the mesh fabric through the coating mechanism, the drying mechanism, and the piercing mechanism in sequence. The coating mechanism includes an insulated raw material tank and coating rollers. The coating rollers are partially embedded in the bottom of the insulated raw material tank, and the coating rollers are rotatably connected to the insulated raw material tank. The circumferential rotation of the coating rollers is driven by a drive motor. The drying mechanism includes an upper drying hood and a lower drying hood arranged opposite each other. Several electric heating tubes are installed inside the upper and lower drying hoods. The puncture mechanism includes a cylinder, a puncture needle plate, and a receiving plate. Two cylinders are arranged opposite each other. The puncture needle plate and the receiving plate are respectively connected to the piston rod ends of the two cylinders. The puncture needle plate is located directly above the receiving plate. Several puncture microneedles are evenly distributed on the lower surface of the puncture needle plate, and a clearance groove is opened on the upper surface of the receiving plate. Under the synchronous drive of the two cylinders, the puncture needle plate and the receiving plate can open and close relative to each other.

[0007] In this mesh fabric production coating device, the frame serves as the supporting framework for the entire device, ensuring the stable installation and operation of each component. The feeding and unloading conveying mechanisms work together to transport the mesh fabric. The mesh fabric is transported from left to right, and it remains suspended and taut at all times during the coating, drying, and piercing processes. The coating mechanism consists of an insulated raw material tank and coating rollers. Molten anti-permeability coating (such as PVC material) is stored in the insulated raw material tank, maintaining a suitable temperature and fluidity. The coating rollers rest against the upper surface of the mesh fabric and are driven to rotate by a drive motor, ensuring the coating is evenly adhered to the rollers. The coating is applied to the mesh fabric. The drying mechanism uses an upper and lower drying hood with an internal electric heating tube to generate heat, which uniformly and efficiently dries the coated mesh fabric, allowing the coating to cure into an impermeable coating. The puncture mechanism consists of a puncture needle plate, a receiving plate, and two cylinders. The two cylinders synchronously drive the puncture needle plate and the receiving plate to open and close relative to each other. When the puncture needle plate and the receiving plate are in contact, several puncture microneedles on the puncture needle plate can perform micropore processing on the impermeable coating to maintain the air permeability of the mesh fabric. The entire process is highly automated and efficient, achieving a balance between impermeability and good air permeability of the mesh fabric, thus improving the overall performance of the mesh fabric.

[0008] In the above-mentioned coating device for producing mesh fabric, the feeding and conveying mechanism includes a guide roller, a traction roller and a drive motor. The guide roller and the traction roller are rotatably connected to the left end of the frame and the traction roller is adjacent to the coating mechanism. The drive motor is connected to the traction roller in a transmission manner.

[0009] In the above-mentioned coating device for producing mesh fabric, the feeding and conveying mechanism includes a guide roller, a traction roller and a drive motor. The guide roller and the traction roller are rotatably connected to the right end of the frame and the guide roller is adjacent to the piercing mechanism. The drive motor is connected to the traction roller in a transmission manner.

[0010] The feeding and unloading conveying mechanisms have the same structure, both consisting of guide rollers, traction rollers, and drive motors. The mesh fabric passes sequentially below the guide rollers of the feeding conveying mechanism, above the traction rollers of the feeding conveying mechanism, above the guide rollers of the unloading conveying mechanism, and below the traction rollers of the unloading conveying mechanism. Two drive motors drive two traction rollers to rotate at appropriate speeds, thereby achieving precise control of the mesh fabric's tension and conveying speed, keeping it taut and conveying it slowly, thus providing support for the smooth progress of the coating work.

[0011] In the above-mentioned coating device for producing mesh fabric, the top of the heat-insulating raw material box has an openable and closable cover, an electric heating wire is embedded in the side wall of the heat-insulating raw material box, a discharge port is opened at the bottom of the heat-insulating raw material box, and the coating roller is located at the discharge port with a small gap between them.

[0012] The molten anti-permeability coating can be added into the insulation material box by opening the cover. The temperature inside the insulation box is kept stable within a suitable range by the electric heating wire to ensure the fluidity of the coating. The coating roller is driven by the drive motor to rotate, and the coating adhering to the surface of the coating roller is carried out from the outlet in an appropriate amount and evenly coated onto the mesh cloth.

[0013] In the above-mentioned coating device for producing mesh fabric, the upper drying hood and the lower drying hood are symmetrically arranged along the horizontal plane where the upper end face of the traction roller is located, and the inner walls of the upper drying hood and the lower drying hood have reflective structures.

[0014] The upper and lower drying hoods are symmetrically arranged along the mesh fabric passing between them. The electric heating tubes inside the upper and lower drying hoods generate heat simultaneously to dry the mesh fabric. There is a certain distance between the electric heating tubes and the mesh fabric to prevent the mesh fabric or coating from being damaged by excessive temperature due to being too close. The reflective structure on the inner wall of the upper and lower drying hoods can reflect the heat of the electric heating tubes, improving energy utilization. The synchronous drying action of the upper and lower hoods can effectively improve the drying efficiency of the coating and the curing quality of the coating.

[0015] In the above-mentioned coating device for producing mesh fabric, the puncture needle plate and the receiving plate are symmetrically arranged along the horizontal plane where the upper end face of the traction roller is located, and the distribution range of the plurality of puncture micro-needles on the puncture needle plate matches the clearance groove.

[0016] The puncture needle plate and the receiving plate are symmetrically arranged along the mesh fabric passing between them. When the two cylinders drive the puncture needle plate and the receiving plate to approach each other synchronously, several puncture microneedles can puncture the mesh fabric, creating several micropores on the coating of the mesh fabric. The receiving plate supports the mesh fabric, preventing it from deforming or breaking due to the puncture force. The clearance groove on the receiving plate ensures that the puncture microneedles can smoothly puncture the mesh fabric without obstruction. After puncture, the cylinder immediately drives the puncture needle plate and the receiving plate to move away from each other and return to their initial positions. When the next area of ​​the mesh fabric is transported to the area below the puncture needle plate, the above steps are repeated to achieve continuous processing. The entire micropore puncture process is fast and does not affect other processes. Depending on the actual situation, a brief stop of the mesh fabric transport can be set during puncture, which is more conducive to the puncture operation.

[0017] In the above-mentioned coating device for producing mesh fabric, the heat-insulating raw material box, the upper drying hood, and the lower drying hood are all connected to the frame via connecting plates, and the two cylinders are all connected to the frame via a gantry frame.

[0018] The connecting plate ensures that the insulated raw material box, upper drying hood, and lower drying hood can be stably connected to the frame, and the gantry frame ensures that the cylinder is stably connected to the frame, thus guaranteeing the stable operation of the coating mechanism, drying mechanism, and piercing mechanism.

[0019] In the above-mentioned coating device for producing mesh fabric, a temperature sensor is provided between the upper drying hood and the lower drying hood, and the temperature sensor is installed on a connecting plate at one end of the upper drying hood.

[0020] Temperature sensors are used to monitor the temperature of the drying area in real time, so as to maintain the heating temperature of the electric heating tube within a suitable range (the specific temperature depends on different mesh cloth and coating materials), avoid the coating or mesh cloth from charring due to excessive temperature, and avoid the coating from not curing sufficiently due to excessive temperature.

[0021] In the above-mentioned coating device for producing mesh fabric, a controller is also provided on the frame. The controller is electrically connected to the drive motor, electric heating wire, electric heating tube, temperature sensor, and cylinder.

[0022] The controller facilitates the setting of process parameters, data collection, and operation control. By controlling the speed of each drive motor, the heating temperature of the electric heating wire and the heating temperature of the electric heating tube, the operation of the cylinder, and the temperature data monitored by the temperature sensor in real time, it can uniformly and accurately control the conveying, coating, drying, and piercing process of the mesh cloth, thereby improving operational efficiency. As the controller is an existing technology, its internal structure will not be described in detail here. In practical applications, a PCL controller can generally be used.

[0023] Compared with existing technologies, this mesh fabric production coating device integrates mesh fabric conveying, coating, drying and puncture processing. The entire process is uniformly controlled and automated, which improves work efficiency. By coating an impermeable coating and drying and curing it, combined with subsequent microporous puncture, the device achieves a balance between the impermeability and breathability of the mesh fabric, thus improving the overall performance of the mesh fabric.

Under the synchronous drive of the two cylinders 8, the puncture needle plate 9 and the receiving plate 10 can open and close relative to each other.

[0032] The feeding and conveying mechanism includes a guide roller 13, a traction roller 14 and a drive motor 4.

The drive motor 4 is connected to the traction roller 14 in a transmission manner.

[0033] The feeding and conveying mechanism includes a guide roller 13, a traction roller 14 and a drive motor 4. The guide roller 13 and the traction roller 14 are rotatably connected to the right end of the frame 1 and the guide roller 13 is adjacent to the piercing mechanism. The drive motor 4 is connected to the traction roller 14 in a transmission manner.

[0034] The insulated raw material box 2 has an openable and closable cover 15 on the top, an electric heating wire 16 is embedded in the side wall of the insulated raw material box 2, and a discharge port 17 is opened at the bottom of the insulated raw material box 2. The coating roller 3 is located at the discharge port 17 and there is a small gap between the two.

[0035] The upper drying hood 5 and the lower drying hood 6 are symmetrically arranged along the horizontal plane where the upper end face of the traction roller 14 is located, and the inner walls of the upper drying hood 5 and the lower drying hood 6 have reflective structures.

[0036] The puncture needle plate 9 and the receiving plate 10 are symmetrically arranged along the horizontal plane where the upper end face of the traction roller 14 is located, and the distribution range of the plurality of puncture microneedles 11 on the puncture needle plate 9 matches the clearance groove 12.

[0037] The insulated raw material box 2, the upper drying hood 5, and the lower drying hood 6 are all connected to the frame 1 via a connecting plate 18, and the two cylinders 8 are all connected to the frame 1 via a gantry frame 19.

[0038] A temperature sensor 20 is provided between the upper drying hood 5 and the lower drying hood 6. The temperature sensor 20 is installed on the connecting plate 18 at one end of the upper drying hood 5.

[0039] The frame 1 is also equipped with a controller 21, which is electrically connected to the drive motor 4, the electric heating wire 16, the electric heating tube 7, the temperature sensor 20, and the cylinder 8.

[0040] In this mesh fabric production coating device, the frame 1 serves as the supporting framework for the entire device, ensuring the stable installation and operation of each component. The feeding and unloading conveying mechanisms work together to transport the mesh fabric. The mesh fabric is transported from left to right, and it remains suspended and taut at all times during the coating, drying, and piercing mechanisms. The coating mechanism consists of an insulated raw material tank 2 and coating rollers 3. Molten anti-permeability coating (such as PVC material) is stored in the insulated raw material tank 2, maintaining a suitable temperature and fluidity. The coating rollers 3 rest against the upper surface of the mesh fabric and are driven to rotate by a drive motor 4, allowing the coating to adhere evenly to the coating rollers 3 and coat the mesh fabric. On the mesh fabric, the drying mechanism uses an upper drying hood 5 and a lower drying hood 6, with an internal electric heating tube 7 to generate a heat source, which uniformly and efficiently dries the coated mesh fabric, allowing the coating to solidify into an impermeable coating. The puncture mechanism consists of a puncture needle plate 9, a receiving plate 10, and two cylinders 8. The two cylinders 8 synchronously drive the puncture needle plate 9 and the receiving plate 10 to open and close relative to each other. When the puncture needle plate 9 and the receiving plate 10 are in contact, several puncture micro-needles 11 on the puncture needle plate 9 can perform micropore processing on the impermeable coating to maintain the air permeability of the mesh fabric. The entire process is highly automated and efficient, achieving a balance between the impermeability and good air permeability of the mesh fabric, thus improving the overall performance of the mesh fabric.

[0041] The feeding and unloading conveying mechanisms have the same structure, both consisting of guide rollers 13, traction rollers 14, and drive motors 4. The mesh fabric passes sequentially below the guide rollers 13 of the feeding conveying mechanism, above the traction rollers 14 of the feeding conveying mechanism, above the guide rollers 13 of the unloading conveying mechanism, and below the traction rollers 14 of the unloading conveying mechanism. Two drive motors 4 drive the two traction rollers 14 to rotate at appropriate speeds, thereby precisely controlling the tension and conveying speed of the mesh fabric, maintaining it in a taut state for slow conveying, and providing support for the smooth progress of the coating work. The molten anti-permeability coating can be added into the heat-insulating raw material box 2 by opening the cover 15. The temperature inside the heat-insulating box is kept stable by the electric heating wire 16. To ensure the fluidity of the coating, the coating roller 3 is driven by the drive motor 4 to rotate, carrying an appropriate amount of coating adhering to the surface of the coating roller 3 out from the discharge port 17 and evenly coating it onto the mesh cloth. The upper drying hood 5 and the lower drying hood 6 are symmetrically arranged along the mesh cloth passing between them. The electric heating tubes 7 inside the upper drying hood 5 and the lower drying hood 6 simultaneously generate heat to dry the mesh cloth, and there is a certain distance between the electric heating tubes 7 and the mesh cloth to prevent the mesh cloth or coating from being damaged by excessive temperature due to too close a distance. The reflective structure on the inner wall of the upper drying hood 5 and the lower drying hood 6 can reflect the heat of the electric heating tubes 7 to improve energy utilization. The synchronous drying action of the upper and lower hoods can effectively improve the drying efficiency of the coating and the curing of the coating. Quality; the puncture needle plate 9 and the receiving plate 10 are symmetrically arranged along the mesh fabric passing between them. When the two cylinders 8 synchronously drive the puncture needle plate 9 and the receiving plate 10 to approach each other, a number of puncture microneedles 11 can puncture the mesh fabric, creating micropores on the coating of the mesh fabric. The receiving plate 10 supports the mesh fabric, preventing it from deforming or breaking downwards due to the puncture force. Furthermore, the clearance groove 12 on the receiving plate 10 ensures that the puncture microneedles 11 can smoothly puncture the mesh fabric without obstruction. After puncture, the cylinder 8 immediately drives the puncture needle plate 9 and the receiving plate 10 to move away from each other and return to their initial positions. When the next area of ​​the mesh fabric is transported to below the puncture needle plate 9, the above steps are repeated to achieve continuous processing. The entire process... The piercing process is fast and does not affect other processes. Depending on the actual situation, the mesh fabric conveying can be briefly stopped during piercing, which is more conducive to the piercing operation. The connecting plate 18 allows the insulated raw material box 2, upper drying hood 5, and lower drying hood 6 to be stably connected to the frame 1. The gantry frame 19 allows the cylinder 8 to be stably connected to the frame 1, ensuring the stable operation of the coating mechanism, drying mechanism, and piercing mechanism. The temperature sensor 20 is used to monitor the temperature of the drying area in real time, so as to maintain the heating temperature of the electric heating tube 7 within a suitable range (the specific temperature depends on different mesh fabrics and coating materials), avoiding the coating or mesh fabric from charring due to excessive temperature, and also avoiding the coating from not being fully cured due to excessively low temperature.The controller 21 is designed to facilitate the setting of process parameters, data acquisition, and operation control. By controlling the speed of each drive motor 4, the heating temperature of the electric heating wire 16, the heating temperature of the electric heating tube 7, the operation of the cylinder 8, and by real-time acquisition of temperature data monitored by the temperature sensor 20, it provides unified and precise control over the conveying, coating, drying, and piercing processes of the mesh fabric, thereby improving operational efficiency. The internal structure of the controller 21, being existing technology, will not be detailed here. In practical applications, a PCL controller is generally used.

For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0043] Those skilled in the art should recognize that the above embodiments are only used to illustrate the present utility model and are not intended to limit the present utility model. Any appropriate changes and variations made to the above embodiments within the scope of the essential spirit of the present utility model shall fall within the scope of protection claimed by the present utility model.
