Description

Technical Field

[0001] This utility model relates to the field of edge banding manufacturing technology, specifically to an environmentally friendly edge banding adhesive application equipment. Background Technology

[0002] The adhesive application process is an essential step in the manufacturing of edge banding strips. Applying adhesive ensures good adhesion and bonding to the substrate later on. After the edge banding strips are extruded from the injection molding machine, they need to undergo embossing and cooling to set their shape before the adhesive application process.

[0003] Traditionally, an open-type traction-based adhesive application method is used to apply glue to edge banding strips. This method lacks a structure for the strip's transmission and limiting, resulting in instability and unreliability during operation, frequent shaking or jumping, severely impacting the adhesive application effect and efficiency. Furthermore, the glued edge banding strips are left to air dry outdoors or in large, well-ventilated workshops to remove odors or glue smells, ensuring the product meets environmental protection requirements before leaving the factory. Clearly, while this traditional method is relatively low-cost, the frequent handling of the edge banding strips causes unnecessary wear and damage, the removal of harmful gases is incomplete, and the efficiency is extremely low, making it unsuitable for large-scale mass production of edge banding strips.

[0004] While some manufacturers utilize specialized drying equipment in separate drying workshops to quickly remove odors or glue smells from edge banding strips, this increases equipment procurement costs and workshop space requirements, leading to higher processing costs. Furthermore, the edge banding strips, after being coated with glue, need to be transferred to other workshops for separate processing, disrupting the seamless connection between different processing steps. This severely impacts edge banding strip manufacturing efficiency, increases production costs, and results in inconsistent glue coating quality, failing to meet the demands of large-scale mass production. Moreover, before the odor or glue smell is significantly eliminated, the glue smell continues to permeate the surrounding environment and workshop during frequent transfers, polluting the air. Over time, this not only seriously threatens the health of nearby residents and workers but also poses a significant threat. Since glue is volatile and flammable, prolonged accumulation in the workshop could easily lead to explosions and fires if improperly handled, creating substantial hazards to edge banding strip production and worker safety.

[0005] In conclusion, it is necessary to further innovate existing technologies. Summary of the Invention

[0035] By adopting the above technical solution, this utility model has the following beneficial effects:

[0036] This utility model of environmentally friendly edge banding adhesive application equipment features a reasonable and compact structure, convenient, safe, and environmentally friendly operation. It integrates adhesive application, heating, cooling, and traction functions into a single unit. Specifically, the adhesive application assembly, heating oven, cold air unit, and edge banding traction assembly are integrated into the same equipment, with the cold air outlet and heating air outlet connected as one unit. This ensures seamless connection between each process, reducing time differences and guaranteeing process continuity. It significantly improves the efficiency and quality of edge banding adhesive application, effectively avoiding the problems of high manufacturing costs, low workshop space utilization, low overall edge banding manufacturing efficiency, and unstable quality associated with using multiple independent devices for each process. It is suitable for large-scale application and meets the needs of mass production of edge banding.

[0037] This invention features multiple edge-sealing strip drive wheels evenly distributed above the heating and cooling air ducts. These drive wheels ensure the edge-sealing strip moves smoothly above the ducts, guaranteeing effective drying and cooling. Simultaneously, adjustable edge-sealing strip anti-jump supports are installed inside the inlet and outside the outlet of the casing, accommodating edge-sealing strips of various widths.

[0040] The glue-applying box of this invention adopts a funnel-shaped structure with a square top and a round bottom, which allows for more thorough glue discharge and prevents glue clumping. The glue-applying roller is height-adjustable through a lifting and adjusting component, enabling the glue-applying roller and the glue-applying roller to handle edge banding strips of different thicknesses, and also facilitating the loading and unloading of edge banding strips. A glue-applying roller scraping component is provided to scrape off excess glue from the outer surface of the rotating glue-applying roller, preventing excessive glue thickness on the outer surface of the glue-applying roller from affecting the glue-applying effect and ensuring the glue-applying effect of the edge banding strip.

[0041] This utility model's edge banding strip traction adopts an open, exposed structure, meaning the traction device is located on the outside of the machine casing. This not only makes operation more convenient and prevents strip stacking, but also facilitates the disassembly, repair, and replacement of the traction wheel. Furthermore, the height of the upper traction wheel is adjustable, which can meet the traction needs of edge banding strips of different thicknesses, making it more versatile. In addition, an anti-pinch plate is installed on the feeding side of the edge banding strip traction assembly, avoiding the risk of employees' hands being pinched due to misoperation during the edge banding strip feeding or traction process.

The glue level alarm 62, low-level and high-level float switches are all connected to an intermediate relay, which is connected to the power output of an emergency stop switch. Specifically, the power input of the intermediate relay is connected to the power output of the emergency stop switch. The normally open contacts of the low-level and high-level float switches are connected in series to the coil circuit of the intermediate relay. When the liquid level is lower than the set value, the low-level float switch closes, energizing the coil of the intermediate relay; when the liquid level is higher than the set value, the high-level float switch closes, energizing the other coil of the intermediate relay. The input terminal of the glue level alarm 62 is connected in parallel with the normally open contact of the intermediate relay. When the low-level float switch or the high-level float switch is triggered, the intermediate relay operates, its contacts close, and the power supply to the glue level alarm 62 is turned on, emitting an audible and visual signal. The low-level float switch and the high-level float switch achieve on / off switching through the magnetic induction of the magnet and the reed switch, which has a simple structure and strong anti-interference ability.

[0069] The main power switch has its power input terminal connected to an external power source and its power output terminal connected to an emergency stop switch. The power output terminal of the emergency stop switch is connected to the main power input terminal of the frequency converter. The power input terminal of the start / stop switch is connected to the power output terminal of the emergency stop switch, and the power output terminal of the start / stop switch is connected to a contactor for controlling the heating oven 3 and a relay for controlling the air cooler unit 4. The power input terminal of the heating switch is connected to the power output terminal of the emergency stop switch, and the power output terminal of the heating switch is connected to a contactor for controlling the heating oven 3. The power input terminal of the fan switch is connected to the power output terminal of the emergency stop switch, and the power output terminal of the fan switch is connected to a relay for controlling the air cooler unit 4.
