Description

Technical Field

[0001] This utility model belongs to the field of plywood production technology, and specifically relates to an environmentally friendly vacuum pressure curing termite-resistant plywood production equipment. Background Technology

[0002] Plywood, as a core material in construction and furniture manufacturing, has termite resistance and environmental friendliness as key indicators of product quality. In the production process of environmentally friendly vacuum-cured termite-resistant plywood, the adhesive application stage is the core process determining bond strength, uniform pesticide penetration, and environmental performance. Traditional plywood adhesive application processes commonly employ roller coating, curtain coating, or spraying. However, in the production of termite-resistant plywood, achieving both adhesive bonding and uniform distribution of the termite-resistant agent simultaneously presents numerous problems, such as uneven application, significant adhesive waste, difficulty in adapting to different board thicknesses, and potential environmental pollution. To improve plywood production quality and efficiency, reduce production costs, and meet increasingly stringent environmental requirements, improvements to the adhesive application structure are urgently needed. Utility Model Content

[0003] The purpose of this utility model is to address the shortcomings of existing technologies by proposing an environmentally friendly vacuum pressure curing termite-resistant plywood production equipment.

[0004] To achieve the above objectives, this utility model adopts the following technical solution: an environmentally friendly vacuum pressure curing termite-resistant plywood production equipment, comprising a shell, with material inlets at both ends of the shell, and a conveying assembly inside the shell, the conveying assembly including a drive roller and a driven roller, the surfaces of the drive roller and the driven roller being connected to each other by a conveyor belt, a scraping assembly at the top of the conveyor belt, the scraping assembly including a heated glue tank, a scraper on one side of the heated glue tank, an adjusting assembly and a moving assembly at the top of the heated glue tank, the adjusting assembly including a horizontal plate, with a screw and a guide rod at both ends inside the horizontal plate, the moving assembly including a threaded block, each threaded block having a fixing block, and a screw connected internally to the threaded block by a threaded screw, and a collecting assembly at the bottom of the conveyor belt, the collecting assembly including a guide frame and a guide frame, with an outer frame fixedly connected to the shell between the guide frame and the guide frame.

[0005] Preferably, a maintenance plate is bolted to one side of the housing, and both the driving roller and the driven roller are rotatably connected to the housing via bearings.

[0006] Preferably, a rotary motor is fixedly installed on one side of the housing, and the output end of the rotary motor is fixedly connected to the drive roller through a coupling.

[0007] Preferably, the bottom of the heated glue tank is connected to a glue head, the other side of the heated glue tank is connected to a connecting pipe, and a mounting plate is bolted to one side of the heated glue tank. The mounting plate and the scraper are fixedly connected to each other.

[0008] Preferably, the screw and the horizontal plate are threaded together, the guide rod and the horizontal plate are slidably connected, the bottom of the screw and the heating glue tank are rotatably connected, the bottom of the guide rod and the heating glue tank are fixedly connected, and a knob is fixedly installed on the top of the screw.

[0009] Preferably, the threaded block and the fixed block are both fixedly connected to the top of the horizontal plate. The fixed block has a guide rod slidably connected inside. Both ends of the guide rod are fixedly connected to a support plate that is fixedly connected to the housing. The screw rod and the support plate are rotatably connected to each other. A rotating motor is fixedly installed on the top of one end of the housing. The rotating motor is fixedly connected to the screw rod through a coupling.

[0010] Preferably, the first guide frame is fixedly connected to the housing, the first guide frame and the second guide frame are fixedly connected by a connecting rod, and the bottom of the first guide frame and the second guide frame are both fixedly installed with a guide frame located at the top of the outer frame.

[0011] Preferably, a collection frame is provided on the inner side of the outer frame, and a snap-fit ​​strip is fixedly installed on both sides of the collection frame. A snap-fit ​​groove is opened inside the outer frame to be used for snap-fit ​​with the snap-fit ​​strip, and a pull ring is fixedly installed on one end of the collection frame.

[0012] In summary, this utility model has the following beneficial effects:

[0013] 1. In the plywood gluing process, this utility model achieves adaptive height adjustment of the heated glue tank and scraper through precise adjustment of a knob. When the knob is turned, the screw linked to it rotates synchronously, driving the heated glue tank to rise and fall vertically along the guide rod through threaded transmission. This setting significantly improves the plywood production line's adaptability to diverse wood sizes, enabling it to be used with wood of different sizes. At the same time, the scraper can be flexibly replaced during long-term use.

[0014] 2. In the wood gluing process of this utility model, a rotating motor drives a conveyor belt to precisely transport the wood to the gluing station. When the wood reaches the set position, the rotating motor stops. Then, the rotating motor starts, driving the horizontal plate to move laterally through the screw, which in turn drives the heated glue tank and scraper to sweep across the wood surface at a uniform speed from left to right, forming a dynamic integrated gluing and smoothing operation. This design solves the core problems of poor uniformity and low efficiency in traditional gluing processes through mechanical structure.

[0015] 3. In the wood gluing process, this utility model optimizes the scraper size to be wider than the conveyor belt but smaller than the inner wall of the outer casing, forming an adaptive width gluing channel that accommodates the gluing needs of wood of various widths. When the scraper moves laterally to level the glue, excess glue on the wood surface overflows to both sides and falls into the guide frames one and two below. Both guide frames one and two adopt a funnel-shaped structure, guiding the accumulated glue towards the collection frame. For subsequent recycling, the glue in the collection frame is poured into an external regeneration heating tank and can be pumped back into the heated glue tank for reuse. This system, through gluing-leveling-recycling, solves the problems of glue waste and environmental pollution in traditional processes. Attached Figure Description

[0040] Brief Description of Usage: In plywood production, this utility model allows for the assembly of external equipment at both ends of the housing 1 to form a production line. Boards requiring glue application enter from one end of the housing 1 and exit from the other. The height of the scraper 305 is adjusted according to the size of the wood. Precise adjustment of the knob 404 allows for adaptive adjustment of the height of the heated glue tank 301 and the scraper 305. Rotating the knob 404 causes the linked screw 403 to rotate synchronously, driving the heated glue tank 301 and the scraper 305 to rise and fall vertically via threaded transmission. The operation of the rotating motor 204 drives the drive roller 201 to rotate. The conveyor belt 203 and driven roller 202 facilitate the transmission of wood across the conveyor belt 203. When the wood reaches the set position, the rotating motor 204 stops. Then, motor 506 is started, driving the horizontal plate 401 to move laterally via screw 503. This causes the heated glue tank 301 and scraper 305 to move uniformly across the wood surface from left to right, forming a dynamic glue application and leveling integrated operation. During the glue application process, the scraper 305 is optimized to be wider than the conveyor belt 203 but smaller than the inner wall of the outer casing, creating an adaptive width glue application channel to accommodate various widths of wood. When the scraper 305 moves laterally to level the glue, excess glue overflows from the wood surface to both sides and falls into the guide frames 601 and 602 below. Both guide frames 601 and 602 adopt a funnel-shaped structure, and the accumulated glue is guided to the collection frame 606 by guide frame 604. For subsequent recycling, the glue in the collection frame 606 is poured into an external regeneration heating tank and can be pumped back into the heated glue tank 301 for reuse.
