Description

Technical Field

[0001] This utility model belongs to the technical field of cleaning devices, specifically relating to a cleaning device for surface treatment of hook and loop fasteners. Background Technology

[0002] Hook and loop fasteners, as mechanical connectors, are widely used in various fields, and their surface quality directly affects the assembly accuracy and service life of products. During production, hook and loop fasteners typically undergo surface treatment processes such as electroplating, spraying, or oxidation. Before these processes, the workpiece surface often contains oil, dust, and other impurities. If not thoroughly cleaned, this will affect the quality of subsequent processes and may even lead to uneven surface treatment and reduced adhesion. Therefore, before surface treatment, effective cleaning equipment must be used to clean and dry the workpiece to ensure a clean surface.

[0003] Currently, common workpiece cleaning equipment on the market mainly includes immersion cleaning, spray cleaning, and ultrasonic cleaning. Among these, spray cleaning is widely used because it can quickly remove surface deposits and is suitable for mass production. However, existing spray cleaning devices still have certain limitations in use. For example, some cleaning devices have fixed spray heads, resulting in a limited spray range and blind spots on the workpiece surface, affecting the cleaning effect; the spray intensity and angle of some cleaning devices cannot be adjusted according to the shape of the workpiece, making it difficult to adapt to different specifications of fasteners; in addition, workpieces usually need to be dried manually or by external equipment after cleaning, which can easily lead to uneven drying or low efficiency, affecting the connection of subsequent processing steps. Utility Model Content

[0004] To address the problems existing in the prior art, the purpose of this utility model is to provide a cleaning device for the surface treatment of latch seats. The device transports the workpiece to the cleaning chamber via a conveyor chain and utilizes a cleaning assembly with a swinging structure to perform large-area rinsing of the workpiece, improving the uniformity and comprehensiveness of the cleaning. Simultaneously, the device integrates a drying chamber, avoiding the problem of residual moisture on the workpiece after cleaning, improving the overall efficiency of cleaning and drying, and ensuring that the workpiece can efficiently and cleanly proceed to subsequent surface treatment processes.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A cleaning device for surface treatment of hook and loop fasteners includes a housing, with a drying chamber and a cleaning chamber respectively located on the left and right sides of the housing. The drying chamber and the cleaning chamber are separated by a partition, and the rear ends of the drying chamber and the cleaning chamber are connected.

[0007] A support frame is installed at the upper end of the partition, and a circulating conveyor chain is installed on the support frame. The conveyor chain uses hooks to send the workpiece into the cleaning chamber and out of the drying chamber.

[0008] Several cleaning components are installed on the right side wall of the partition and the shell. While rinsing the workpiece in the cleaning chamber, the cleaning components can swing up and down to change the rinsing angle.

[0009] Furthermore, the cleaning assembly includes a mounting base installed on the partition or the side wall of the housing and an eccentric mechanism installed on the partition or the side wall of the housing, both of which have openings for mounting the mounting base.

[0010] A water spray component that sprays water into the cleaning chamber is rotatably mounted on the mounting base. One end of the water spray component is hinged to a connecting rod, and an eccentric mechanism drives the connecting rod to make the water spray component swing up and down.

[0011] Furthermore, the water spray component includes a hollow swing arm, which is mounted on a mounting base using rotating shafts on both sides. A water spray box is fixed to one end of the swing arm facing the cleaning chamber, and multiple nozzles are fixed to one side of the water spray box. A connecting pipe is fixed to the other end of the swing arm.

[0012] Furthermore, the mounting base is designed as an inverted U-shape, and both sides of the mounting base are fixed with mounting edges.

[0013] Furthermore, the eccentric mechanism includes a motor, a turntable fixed on the output shaft of the motor, and an eccentric shaft fixed on one side of the turntable, which is rotatably connected to the lower end of the connecting rod.

[0014] Furthermore, a semi-circular connector is fixed to one end of the motor's output shaft, and the connector passes through the turntable and is connected to a fixing screw.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] This utility model provides a cleaning device for the surface treatment of hook and loop fasteners. It continuously transports the workpiece via a conveyor chain and uses a cleaning assembly capable of vertical oscillation within the cleaning chamber for efficient rinsing. This avoids the problems of limited spray range and blind spots found in existing spray cleaning devices. The cleaning assembly utilizes an eccentric mechanism to drive a connecting rod, causing the water spray component to oscillate vertically while uniformly spraying high-pressure water through nozzles. This provides comprehensive coverage of the workpiece surface from multiple angles, improving the cleaning effect and ensuring the hook and loop fasteners reach optimal cleanliness before entering subsequent surface treatment processes, thereby enhancing the surface treatment quality.

[0017] This utility model's cleaning assembly adopts a hollow swing arm structure, with a water spray box at one end of the swing arm. Multiple nozzles are evenly distributed on the water spray box, and a stable high-pressure water flow is provided by a water pump supply system, ensuring that the water flow is evenly distributed on the workpiece surface. Compared to traditional fixed-nozzle cleaning methods, this design effectively avoids the cleaning dead angle problem caused by a fixed spray angle, improving adaptability to complex workpiece structures. Simultaneously, all connecting parts of the cleaning assembly are made of high-strength alloy materials, coupled with wear-resistant bushings and corrosion-resistant lubricating grease, increasing the assembly's service life, reducing maintenance frequency, and improving the stability and reliability of the equipment.

[0018] This invention incorporates a drying chamber at the end of the cleaning process. The drying chamber integrates a high-efficiency hot air circulation system, enabling rapid drying of the cleaned workpieces and avoiding the reliance on external drying equipment or manual air drying found in traditional methods. This design not only improves the drying speed and prevents surface treatment quality degradation due to water residue, but also reduces manual operation and increases overall work efficiency. Furthermore, the airtight design of the drying chamber effectively prevents external dust from entering, ensuring the cleanliness of the workpieces during the drying process and further optimizing the effect of subsequent surface treatments.

[0019] This utility model's conveyor chain system adopts a circulating rolling structure, enabling continuous conveying of workpieces and achieving integrated cleaning and drying operations. This avoids the problems of workpiece accumulation and low efficiency caused by traditional manual handling or intermittent conveying methods. The hook structure on the conveyor chain is optimized to ensure stable suspension of workpieces during conveying, preventing shaking or detachment from affecting the cleaning and drying effects. Furthermore, the conveyor chain is made of high-temperature and corrosion-resistant stainless steel and features a standard pitch design, allowing it to adapt to different sizes of latches and improving the equipment's versatility.

[0020] The eccentric mechanism of this invention is driven by a servo motor, which in turn drives the connecting rod and water spray component to swing via the eccentric shaft. Compared to traditional mechanical swing structures, this design enables more precise swing control and allows adjustment of the swing frequency according to workpiece size or cleaning requirements, improving the applicability of the equipment. The variable frequency speed control system of the servo motor further enhances the operational stability of the cleaning components, ensuring efficient and stable operation under various cleaning conditions. Simultaneously, the compact design of the eccentric mechanism minimizes space occupation, facilitating overall equipment integration and maintenance, and improving the ease of use and durability of the cleaning device.

[0021] This utility model features an optimized and rational overall structure. All key components are manufactured using high-strength, corrosion-resistant materials and treated with rust-proofing and anti-loosening processes, improving the equipment's durability and long-term operational stability. The modular installation design facilitates subsequent maintenance and component replacement, reducing equipment downtime and increasing production efficiency. Furthermore, the overall airtight design effectively reduces water mist diffusion during cleaning, minimizing environmental pollution and optimizing the factory's internal working environment, thus enhancing operator safety and comfort.

[0029] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model. Example

[0030] like Figure 1As shown, a cleaning device for surface treatment of hook and loop fasteners includes a housing 1 made of corrosion-resistant stainless steel to ensure that it is not affected by cleaning fluid and moisture during long-term use, thus improving the durability and stability of the equipment. The left and right sides of the interior of the housing 1 are respectively set as a drying chamber 4 and a cleaning chamber 7, which are separated by a partition 5. The partition 5 is made of 5mm thick aluminum alloy plate, which ensures both structural strength and good corrosion resistance. The partition 5 is also provided with several ventilation holes to ensure the discharge of water mist after cleaning, thereby improving drying efficiency. The rear ends of the drying chamber 4 and the cleaning chamber 7 are connected, so that the workpiece can directly enter the drying chamber 4 after cleaning, reducing manual operation steps and improving the continuity and overall efficiency of cleaning and drying.

[0031] A support frame 2 is installed on the upper end of the partition 5. The support frame 2 is made of Q235 carbon steel and is fixed to the partition 5 by welding to ensure the stability and durability of the overall structure. A circulating conveyor chain 3 is installed on the support frame 2. The conveyor chain 3 is made of high-temperature and corrosion-resistant stainless steel, and the chain pitch is set to a standard 50mm to adapt to the suspension requirements of workpieces of different sizes. Several hooks 6 are evenly distributed on the conveyor chain 3. The hooks 6 are made of high-strength alloy steel and are galvanized to prevent rusting during long-term use. The hooks 6 are used to stably hang and transport the workpieces into the cleaning chamber 7. After rinsing, they continue to enter the drying chamber 4 and are finally transported to the equipment outlet by the conveyor chain 3. The operator can directly remove them to complete the cleaning and drying process.

[0032] Several cleaning components 8 are installed on the right side wall of both the partition 5 and the shell 1. The cleaning components 8 adopt the spray cleaning method and use high-pressure water flow to thoroughly rinse the workpiece. While rinsing the workpiece in the cleaning chamber 7, the cleaning components 8 can swing up and down to change the rinsing angle, so that the water flow can cover all parts of the workpiece surface, avoid cleaning blind spots, and improve the overall cleaning effect.

[0033] like Figure 1 and Figure 2As shown, the cleaning assembly 8 includes a mounting base 82 installed on the side wall of the partition 5 or the housing 1. The mounting base 82 is made of corrosion-resistant aluminum alloy and coated with anti-rust paint to enhance durability. The mounting base 82 is fixed to the side wall of the partition 5 or the housing 1 by high-strength stainless steel bolts to ensure installation stability. The internal hollow design of the mounting base 82 facilitates the arrangement of pipes and related components, improving the neatness and safety of wiring and piping. In addition, the cleaning assembly 8 also includes an eccentric mechanism 84 installed on the side wall of the partition 5 or the housing 1. The eccentric mechanism 84 is manufactured using high-precision machining technology to ensure a stable up-and-down movement trajectory when driving the connecting rod 83. The side wall of the partition 5 or the housing 1 is provided with an opening for installing the mounting base 82. The opening size is precisely matched according to the specifications of the mounting base 82 to ensure that the mounting base 82 can be firmly embedded and to avoid loosening or displacement that would affect the cleaning effect.

[0034] like Figure 2 As shown, a water spraying component 81 for spraying water into the cleaning chamber 7 is rotatably mounted on the mounting base 82. The interior of the water spraying component 81 adopts a high-pressure sealing structure to prevent water leakage. A connecting rod 83 is hinged to one end of the water spraying component 81. The connecting rod 83 is made of high-strength stainless steel and wear-resistant bushings are used at the connection parts to improve service life and reduce movement resistance. An eccentric mechanism 84 drives the connecting rod 83 to make the water spraying component 81 swing up and down, so that the water spraying component 81 can efficiently rinse the workpiece at different heights and angles, thereby improving the cleaning coverage.

[0035] like Figure 3 As shown, the water spray component 81 includes a hollow swing arm 814, which is made of seamless stainless steel tubing and has a high-pressure resistant water pipe installed inside the tubing wall to ensure that the water flow can be evenly delivered to each nozzle 811. The swing arm 814 is mounted on the mounting base 82 using rotating shafts 813 on both sides. The rotating shafts 813 are made of alloy steel and the bearing parts are coated with corrosion-resistant grease to reduce friction and improve the smoothness of movement. A water spray box 812 is fixed to the end of the swing arm 814 facing the cleaning chamber 7. The water spray box 812 is made of high-pressure resistant steel tubing. Made of high-pressure polymer material, it can withstand water pressure up to 0.8MPa to ensure stable water flow. Multiple nozzles 811 are fixed on one side of the water spray box 812. The orifice diameter of the nozzles 811 is set to 0.3mm to ensure that the sprayed water mist has a good atomization effect, while ensuring that the water pressure is sufficient to remove dirt and impurities from the surface of the workpiece. A connecting pipe 815 is fixed to the other end of the swing arm 814. The connecting pipe 815 is made of high-temperature resistant reinforced hose and is connected to the water supply system through a high-pressure connector to ensure unobstructed water flow.

[0036] like Figure 4As shown, the mounting base 82 is designed as an inverted U-shape. The inverted U-shape structure can enhance the overall strength of the mounting base 82 and provide better stability, preventing loosening due to vibration during long-term operation. Both sides of the mounting base 82 are fixed with mounting edges 821, which are fastened to the housing 1 or partition 5 by bolts. The bolts are made of stainless steel with M8 specifications to ensure that the installation is firm and can withstand the vibration and impact during equipment operation.

[0037] like Figure 5 As shown, the eccentric mechanism 84 includes a motor 841, which is a 120W DC servo motor. The speed is controlled by a frequency conversion speed regulation system, enabling the eccentric mechanism 84 to adjust the rinsing rhythm under different working conditions and improve cleaning adaptability. A turntable 842 is fixed on the output shaft of the motor 841. The turntable 842 is made of high-strength alloy steel and its surface is precision ground to ensure stability during rotation. An eccentric shaft 843 is fixed on one side of the turntable 842 and is rotatably connected to the lower end of the connecting rod 83. The eccentricity of the eccentric shaft 843 is set to 10mm to ensure that the swing arm 814 can achieve sufficient up and down movement range, thereby covering a wider cleaning range.

[0038] like Figure 5 As shown, a semi-circular connector 845 is fixed to one end of the output shaft of the motor 841. The connector 845 is made of wear-resistant copper alloy and has been hardened on the surface to improve its wear resistance. The connector 845 passes through the turntable 842 and is connected to a fixing screw 844. The fixing screw 844 is made of high-strength stainless steel and has been treated to prevent loosening, so as to ensure that it will not loosen due to vibration during long-term operation, thereby ensuring the motion accuracy and long-term stability of the eccentric mechanism 84. Example

[0039] This embodiment provides a cleaning device for surface treatment of hook and loop fasteners, including a conveyor chain system, a cleaning assembly, and a drying system. The conveyor chain 3 is made of 304 stainless steel, with a chain width of 50mm. The chain links are connected by high-strength, wear-resistant hinges, capable of withstanding the weight of the hook and loop fasteners and the impact force generated during rinsing, ensuring long-term stable operation. The hook 6 is made of high-strength alloy steel, with a load-bearing capacity of 10kg. Its surface is treated with an anti-rust coating to prevent corrosion caused by prolonged exposure to moisture. The conveyor chain 3 is driven by a variable frequency motor with a power of 750W, and its speed can be adjusted via a PLC control system to adapt to the cleaning and drying needs of different workpieces.

[0040] The cleaning assembly 8 controls the water spray component 81 to swing up and down via an eccentric mechanism 84. The eccentric mechanism 84 includes a 120W DC servo motor, with a 120mm diameter turntable 842 fixed on the motor output shaft. An eccentric shaft 843 is mounted on one side of the turntable 842, with an eccentricity set to 10mm, ensuring that the connecting rod 83 drives the water spray component 81 to swing back and forth, with the swing amplitude controlled within ±30°. The water spray component 81 consists of a hollow swing rod 814, a water spray box 812, and multiple nozzles 811. The swing rod 814 has a diameter of 25mm and a length of 300mm, and is made of high-strength, corrosion-resistant aluminum alloy with a polytetrafluoroethylene coating to reduce scale adhesion. The nozzles 811 adopt a stainless steel microporous structure with an orifice diameter of 0.3mm, which can form a fine water mist, effectively improving rinsing efficiency.

[0041] This embodiment uses a conveyor chain to stably transport the workpiece, and combines this with the oscillating rinsing method of the cleaning component to ensure that the water flow can fully cover the surface of the workpiece, thereby avoiding blind spots in cleaning, improving cleaning quality, reducing cleaning time, and increasing production efficiency. Example

[0042] This embodiment addresses the limitation of the spray range in traditional fixed nozzles by providing a water spray assembly with an adjustable spray angle. The water spray component 81 adopts a hollow swing rod 814 structure, with a length of 350mm and a wall thickness of 2mm. The swing rod 814 contains a high-pressure resistant water pipe capable of withstanding a water pressure of 0.8MPa. The water spray box 812 is made of high-temperature resistant ABS engineering plastic. Ten nozzles 811 are evenly distributed along the length of the water spray box 812. The angle of each nozzle can be finely adjusted within a range of ±15° to accommodate workpieces of different sizes and structures.

[0043] The water pump system uses a 1.5kW high-pressure centrifugal pump with a maximum output flow rate of 200L / min. High-pressure water is delivered to each nozzle to ensure even coverage of the workpiece surface. The water inlet pipe of the spray box 812 is made of high-temperature and corrosion-resistant fluororubber hose with a diameter of 15mm and is equipped with a stainless steel quick connector for easy disassembly and maintenance. During operation, the spray component 81 drives the connecting rod 83 to swing up and down via an eccentric mechanism 84. This allows the spray box 812 to adjust its rinsing angle according to the swing of the rod 814, ensuring that the water flow covers all surfaces of the workpiece.

[0044] This embodiment optimizes the structure of the water spray assembly, thereby increasing the coverage of the water flow during the cleaning process and effectively avoiding the cleaning blind spot problem caused by the limited spray angle in traditional cleaning methods, thus significantly improving the cleanliness of the workpiece surface. Example

[0045] This embodiment provides a high-efficiency hot air circulation drying system to solve the problem of relying on external equipment or manual air drying after traditional workpiece cleaning. The drying chamber 4 adopts a double-layer insulated stainless steel structure and is equipped with a high-efficiency hot air circulation system. The hot air blower has a power of 3kW and a maximum output temperature of 120℃, which can be precisely controlled by a PID temperature control system. The internal air ducts of the drying chamber 4 feature an adjustable airflow design, with an airflow range of 2m / s-5m / s, which can be adjusted according to the material and size of the workpiece to ensure uniform drying.

[0046] The conveyor chain 3 operates at a speed of 5 m / min within the drying chamber 4, ensuring that the workpiece is dried within 60 seconds. Hot air is blown onto the workpiece surface from the air inlet at the top of the drying chamber and circulates through the return air inlet at the bottom, thereby improving drying efficiency. The drying chamber 4 is equipped with a dust filter with a filtration accuracy of 0.3 μm to prevent dust in the air from entering the drying chamber and adhering to the workpiece surface, ensuring that the dried workpiece remains clean.

[0047] This embodiment utilizes a high-efficiency hot air circulation system, combined with precise temperature control and adjustable wind speed design, to enable workpieces to dry in a short time, while avoiding the water stain residue problem caused by traditional air drying methods, thus improving the quality and production efficiency of surface treatment processes. Example

[0048] This embodiment optimizes the conveying system to address the inefficiency of traditional manual handling or intermittent conveying methods. The conveyor chain 3 employs a dual-rail stable operation structure, with both sides supported by 40×40mm square tubing and secured with M10 stainless steel bolts, ensuring the chain does not shift or wobble during operation. The chain drive mechanism uses a 750W variable frequency motor, combined with a PLC automatic control system, to achieve an adjustable conveying speed range of 2m / min-8m / min, adapting to different production needs.

[0049] The hook 6 adopts a double-layer anti-slip design, with a silicone protective sleeve on the outer layer to prevent the workpiece from being scratched and damaged due to shaking during the conveying process; the hook 6 has a load-bearing capacity of 15kg and is evenly distributed on the conveyor chain 3 through a standardized spacing (100mm) to ensure that multiple workpieces can be conveyed stably.

[0050] This embodiment improves the stability of workpiece conveying by optimizing the conveyor chain structure and drive control system, reduces manual intervention, and increases the efficiency of automated cleaning and drying, thereby improving the overall production line efficiency and workpiece processing quality. Example

[0051] This embodiment optimizes the eccentric mechanism 84 to improve the operational stability and durability of the equipment. The core component of the eccentric mechanism 84 includes a 120W DC servo motor with an adjustable speed range of 0-3000 rpm, and is precisely speed-regulated in conjunction with a frequency converter. The eccentric shaft 843 is made of high-strength alloy steel and undergoes nitriding treatment, achieving a surface hardness of HV600, ensuring that it is not easily worn during long-term high-speed operation.

[0052] This embodiment improves the operational stability of the water spray assembly by optimizing the material selection and driving method of the eccentric mechanism, enabling it to maintain precise oscillation over a long period of time, thereby ensuring the uniformity and efficiency of workpiece cleaning.

[0053] The working principle of this utility model is as follows: When cleaning the workpiece, it is hung on the conveyor chain 3 using the hook 6. At this time, the conveyor chain 3 rolls and transports the workpiece into the cleaning chamber 7. Meanwhile, the cleaning components 8 on the partition 5 and the side wall of the shell 1 rinse the workpiece.

[0054] When the cleaning assembly 8 is rinsing, the motor 841 drives the turntable 842 to rotate. The turntable 842 drives the connecting rod 83 to move up and down through the eccentric shaft 843. The up-and-down moving connecting rod 83 drives the swing rod 814 to swing up and down. At this time, water is supplied into the swing rod 814 through the water pump and water pipe. The water entering the swing rod 814 is sprayed out through multiple nozzles 811 to rinse the workpiece. At the same time, the water follows the up-and-down swing of the swing rod 814 to rinse the workpiece over a large area.

[0055] After cleaning, the workpiece is conveyed into the drying chamber 4 by the conveyor chain 3. The workpiece is then dried by the drying equipment in the drying chamber 4. The dried workpiece is then sent out, and the operator can directly remove the workpiece, thus completing the cleaning and drying process.

[0056] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the field.
