Equipment for uniformly coating abrasion-resistant coating on fishing net monofilaments

Abstract

This utility model relates to the field of fishing net production technology and discloses a device for uniformly coating a wear-resistant coating on fishing net monofilaments. The device includes a housing, with a placement plate fixedly connected inside. A bracket is fixedly connected to one side of the top of the placement plate, and a drive motor is fixedly connected to one side of the bracket. This utility model uses the drive motor to drive a cleaning roller to rotate, causing a first and second pulley to drive a circular plate to rotate via a rotating rod. This, in turn, causes a connecting rod to push a movable plate in reciprocating motion, which in turn causes a piston plate to create a negative pressure adsorption effect within the suction box. This allows harmful gases volatilized during the coating process and dust generated during cleaning to be drawn into a filter box through a suction pipe. The filter plate intercepts and purifies particulate matter and chemical pollutants in the gas, thereby reducing the concentration of harmful gases in the workshop. This not only ensures the health and safety of operators but also avoids the corrosive effects of harmful gases on workshop equipment and the environment.

Description

Technical Field

[0001] This utility model relates to the field of fishing net production technology, and in particular to a device for uniformly coating a wear-resistant coating on fishing net monofilaments. Background Technology

[0002] The equipment for uniformly coating abrasion-resistant monofilaments of fishing nets is a precision coating device specifically designed for the fishing net manufacturing industry. Its core function is to use automated control technology to attach high-molecular abrasion-resistant materials (such as polyurethane and polyethylene) to the surface of the fishing net monofilaments in a uniform and continuous film form. By precisely controlling parameters such as coating thickness, tension, and drying temperature, the equipment forms a durable and robust protective layer on the monofilament surface, which can significantly improve the abrasion resistance, seawater corrosion resistance, and UV resistance of the fishing net fibers. This extends the service life of the fishing net in complex marine environments, reduces the risk of breakage due to friction, and maintains the flexibility and lightweight characteristics of the fishing net. It is one of the key pieces of equipment for the efficient production of modern fishing gear.

[0003] Existing equipment for uniformly coating wear-resistant monofilaments of fishing nets still has some problems during use. For example, when coating fishing net monofilaments, the coating material emits harmful gases, and most existing devices cannot effectively purify them, causing these harmful gases to diffuse directly into the workshop air. This not only threatens the health of operators but may also react chemically with other equipment or substances in the workshop, affecting the safety and stability of the production environment.

[0004] To address these issues, we provide a device for uniformly coating abrasion-resistant coatings onto fishing net monofilaments. Summary of the Invention

[0005] The technical problem to be solved by this utility model is that the existing technology has the disadvantage of not being able to purify the harmful gases emitted during coating, which will affect the environment and equipment in the workshop. To this end, we propose a device for uniformly coating abrasion-resistant coating on fishing net monofilaments.

[0006] To achieve the above objectives, this application adopts the following technical solution: a device for uniformly coating abrasion-resistant coating on fishing net monofilaments, comprising a box body, a placement plate fixedly connected inside the box body, a support fixedly connected to one side of the top of the placement plate, a drive motor fixedly connected to one side of the support, a cleaning roller fixedly connected to the output end of the drive motor, a coating device body fixedly connected to the other side of the top of the placement plate, an air suction box fixedly connected to the top of the inner cavity of the box body, a rotating rod rotatably connected inside the air suction box, a circular plate fixedly connected to one end of the rotating rod, a connecting rod fixedly connected to one side of the circular plate, a movable plate provided on one side of the circular plate, a movable groove opened inside the movable plate, the connecting rod slidably connected inside the movable groove, push plates fixedly connected to both sides of the movable plate, a piston plate fixedly connected to one side of the push plate, a first pulley fixedly connected to one side of the surface of the cleaning roller, a second pulley fixedly connected to one side of the surface of the rotating rod, air suction pipes connected to both sides of the bottom of the air suction box, a filter box connected to the bottom of the air suction pipes, a filter plate provided inside the filter box, an air suction port connected to the bottom of the filter box, and exhaust pipes connected to both sides of the air suction box.

[0007] Preferably, a first one-way valve is provided on the surface of the intake pipe, and a second one-way valve is provided on the surface of the exhaust pipe.

[0008] Preferably, a limiting plate is provided inside the air intake box, and the push plate is slidably connected inside the limiting plate.

[0009] Preferably, a mounting plate is fixedly connected to one side of the top of the inner cavity of the box, and one end of the rotating rod is rotatably connected to one side of the mounting plate through a rotating shaft.

[0010] Preferably, conveying channels are provided on both sides of the box body for conveying fishing net monofilaments.

[0011] Preferably, guide plates are fixedly connected to both sides of the inner wall of the filter box, and the filter plates are slidably connected to the surface of the guide plates.

[0012] Preferably, a sliding groove is provided on one side of the filter box, and the filter plate is slidably connected inside the sliding groove.

[0013] The technical effects and advantages of this utility model are as follows: 1. This utility model, through the setting of a transmission motor, can drive the cleaning roller to rotate. The cleaning roller, through the first and second pulleys, causes the rotating rod to drive the circular plate to rotate, thereby pushing the movable plate to reciprocate through the connecting rod. This, in turn, causes the piston plate to form a negative pressure adsorption effect in the suction box, thereby drawing harmful gases volatilized during the coating process and dust generated during cleaning into the filter box through the suction pipe. The filter plate intercepts and purifies the particulate matter and chemical pollutants in the gas. The purified gas is safely discharged through the exhaust pipe, significantly reducing the concentration of harmful gases in the workshop. This not only protects the health and safety of operators but also avoids the corrosive effects of harmful gases on workshop equipment and the environment.

[0014] 2. This utility model, through the setting of sliding groove and limiting plate, enables quick replacement of filter plate, ensuring long-term stable filtration efficiency. The first one-way valve and the second one-way valve can prevent gas backflow, thereby maintaining unidirectional airflow and improving the reliability of the purification device. Furthermore, the cleaning roller can remove impurities from the surface of monofilaments during the pretreatment stage, reducing coating defects. Through the cooperation between the air suction box and the coating device body, dust and chemical gases can be filtered and purified simultaneously, thereby improving the working environment of the workshop.

[0023] Specifically: the placement plate 2 can easily fix the bracket 3 and the coating device body 6. The drive motor 4 can drive the rotating rod 8 and the cleaning roller 5 to rotate, thereby achieving the purpose of air intake and pre-cleaning. The coating device body 6 can coat the fishing net monofilaments with a wear-resistant coating. This device is existing technology and will not be described in detail here. The surface of the rotating rod 8 is rotatably connected to the inside of the air intake box 7 through a rotating shaft. It can drive the circular plate 9 to rotate, thereby driving the piston plate 13 to move back and forth, thereby achieving the purpose of air intake and exhaust. The first pulley 14 and the second pulley 15 are both connected by belt drive, thereby achieving the purpose of driving the piston plate 13 and the cleaning roller 5 to rotate simultaneously through a single drive motor 4. There are two filter plates 18, both of which are activated carbon filter plates 18. They can filter and purify particles and harmful gases in the air. There are two air intake ports 19, one set inside the bracket 3 and the other set inside the coating device body 6. They can absorb the harmful gases generated during coating and the dust generated during cleaning.

[0024] Example 2 Please see Figures 1-5Based on Embodiment 1, a first one-way valve 21 is provided on the surface of the air intake pipe 16, a second one-way valve 22 is provided on the surface of the exhaust pipe 20, a limiting plate 23 is provided inside the air intake box 7, a push plate 12 is slidably connected to the inside of the limiting plate 23, an mounting plate 24 is fixedly connected to one side of the top of the inner cavity of the box 1, one end of the rotating rod 8 is rotatably connected to one side of the mounting plate 24 through a rotating shaft, conveying grooves 25 are provided on both sides of the box 1, and the conveying grooves 25 are used to convey fishing net monofilaments, guide plates 26 are fixedly connected to both sides of the inner wall of the filter box 17, the filter plate 18 is slidably connected to the surface of the guide plate 26, a sliding groove 27 is provided on one side of the filter box 17, and the filter plate 18 is slidably connected to the inside of the sliding groove 27.

[0025] Specifically: the first one-way valve 21 and the second one-way valve 22 can control the flow of air to achieve the purpose of air intake and exhaust; the mounting plate 24 can provide support for the rotating rod 8; one end of the rotating rod 8 is rotatably connected to one side of the mounting plate 24 through a rotating shaft; the guide plate 26 can limit and support the push plate 12 to ensure that it will not deviate when it moves laterally; and the sliding groove 27 can facilitate the disassembly and assembly of the filter plate 18.

[0026] Working principle: When it is necessary to coat the fishing net monofilament with a wear-resistant coating, firstly, the fishing net monofilament enters the equipment through the conveying grooves 25 on both sides of the box 1. Then, the user starts the drive motor 4 through the external controller. The drive motor 4 drives the cleaning roller 5 to rotate, thereby pre-cleaning the surface of the fishing net monofilament.

[0027] Simultaneously, the cleaning roller 5 drives the first pulley 14 to rotate, which in turn drives the second pulley 15 to rotate via a belt. This, in turn, drives the rotating rod 8 to rotate synchronously. The rotating rod 8 drives the circular plate 9 to rotate, which in turn drives the connecting rod 10 to reciprocate within the movable groove 28. This, in turn, pushes the movable plate 11 to move laterally back and forth, thereby driving the push plates 12 and piston plates 13 on both sides to reciprocate within the suction box 7. When the piston plates 13 move to both sides of the inner cavity of the suction box 7, the first one-way valve 21 closes and the second one-way valve 22 opens. When the air inside the suction box 7 is discharged through the exhaust pipe 20, the first one-way valve 21 opens and the second one-way valve 22 closes when the piston plate 13 moves toward the center of the inner cavity of the suction box 7. This allows the harmful gases generated during spraying and the dust generated during cleaning to be drawn into the filter box 17 through the suction port 19. After being filtered and adsorbed by the filter plate 18, the dust enters the suction box 7 through the suction pipe 16. This filters and adsorbs the harmful gases generated during coating and the dust generated during cleaning, thereby reducing the harm to the air in the workshop.
