Description

Technical Field

[0001] This utility model relates to the field of bamboo plywood processing technology, specifically to a glue-impregnation device for producing resistant-bending bamboo plywood. Background Technology

[0002] In the bamboo plywood production industry, the impregnation process is the core factor that determines the bending resistance of the board.

[0003] Currently, some equipment uses a fixed soaking structure, requiring bamboo to be manually transported and placed into the soaking tank. This is not only labor-intensive, but also prone to causing the bamboo to shake during placement and removal, leading to glue splashing. This poses safety hazards and affects the uniformity of the soaking. In addition, the bamboo fixing methods of traditional equipment are relatively simple, often using binding or simple slots. During the soaking process, the bamboo is prone to sliding or shifting, resulting in insufficient or excessive glue in some areas. This reduces the interlayer bonding strength of the bamboo plywood, leading to problems such as delamination and bending deformation during use. Utility Model Content

[0004] (a) Technical problems to be solved To address the shortcomings of existing technologies, this utility model provides a glue-impregnation equipment for the production of anti-bending bamboo plywood. It solves the problems of unstable lifting, inconvenient fixing, complex operation, and poor glue-impregnation quality of traditional glue-impregnation equipment by using an integrated lifting and extraction device design.

[0005] (II) Technical Solution To achieve the above objectives, this utility model provides the following technical solution: a resin impregnation device for producing anti-bending bamboo plywood, comprising: an impregnation tank, a lifting device fixedly connected to the top of the impregnation tank, the lifting device being lifted by pulling, an extraction device slidably connected to the inner wall of the lifting device, the lifting device including a support frame, a winch fixedly connected to the side wall of the support frame, a concentrator wheel rotatably connected to the outer wall of the support frame, and steel ropes symmetrically rotatably connected to the outer wall of the concentrator wheel. The winch can precisely control the lifting speed and height, ensuring that the bamboo is stably impregnated into or removed from the impregnation tank, avoiding resin splashing or bamboo displacement due to shaking.

[0006] Preferably, the bottom end of the support frame is fixedly connected to the top end of the soaking tank, and one end of the steel rope is fixedly connected to the outer wall of the winch.

[0007] Preferably, the outer wall of the steel rope is rotatably connected to a labor-saving wheel, and the end of the steel rope away from the winch is fixedly connected to a central ring. The inner wall of the labor-saving wheel is rotatably connected to the outer wall of the support frame. The labor-saving wheel effectively reduces steel rope friction, reduces equipment wear, and extends service life.

[0008] Preferably, the outer wall of the concentrating ring is symmetrically slidably connected with a pull rope, and the end of the pull rope away from the concentrating ring is fixedly connected to a lifting frame. The outer wall of the lifting frame is in contact with the inner wall of the soaking tank, and the lifting frame is in close contact with the inner wall of the soaking tank. The immersion depth and soaking time can be flexibly adjusted according to the bamboo impregnation requirements to ensure that the adhesive fully penetrates the bamboo and improve the bending resistance of the bamboo plywood.

[0009] Preferably, the extraction device includes a placement frame, with limit blocks symmetrically fixedly connected to the outer wall of the lifting frame, baffles slidably connected to the outer wall of the limit blocks, and pins slidably connected to the inner walls of the limit blocks and baffles. In the extraction device, the placement frame can slide flexibly within the lifting frame, facilitating the operator to accurately place the bamboo material in the designated position. The cooperative design of the limit blocks, baffles, and pins enables quick locking and unlocking of the placement frame, making the fixing process simple and efficient, effectively preventing the bamboo material from sliding or shifting during the impregnation process, and ensuring the uniformity of the impregnation.

[0010] Preferably, the outer wall of the placement frame is slidably connected to the inner wall of the lifting frame, the inner wall of the placement frame holds the workpiece, and the outer wall of the pin is slidably connected to the inner wall of the lifting frame.

[0011] Beneficial effects This utility model provides a resin impregnation device for producing flexurally resistant bamboo plywood. It has the following beneficial effects: This utility model achieves stable, drag-type lifting of the lifting frame through the coordination of a lifting device and an extraction device. The labor-saving wheel effectively reduces steel cable friction and equipment wear. The winch precisely controls the lifting speed and height, ensuring the bamboo is smoothly immersed in or removed from the soaking tank, preventing glue splashing or bamboo displacement due to shaking. The lifting frame maintains close contact with the inner wall of the soaking tank, allowing for flexible adjustment of the immersion depth and soaking time according to the bamboo's glue requirements, ensuring full glue penetration and improving the bamboo plywood's bending resistance.

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0015] Example Please see Figure 1-5 This utility model provides a technical solution: a resin impregnation device for producing flexurally resistant bamboo plywood, comprising: Soaking tank 1, with a lifting device 2 fixedly connected to the top of soaking tank 1. The lifting device 2 is raised and lowered by pulling. The inner wall of the lifting device 2 is slidably connected to an extraction device 3. The bamboo plywood can be integrated during the soaking process through the lifting device 2, and the bamboo plywood can be quickly replaced through the extraction device 3. The lifting device 2 includes a support frame 20, a winch 21 is fixedly connected to the side wall of the support frame 20, a concentrator 22 is rotatably connected to the outer wall of the support frame 20, and a steel rope 23 is symmetrically rotatably connected to the outer wall of the concentrator 22. The bottom end of the support frame 20 is fixedly connected to the top end of the soaking tank 1, and one end of the steel rope 23 is fixedly connected to the outer wall of the winch 21. After the bamboo is fixed, the lifting device 2 is started, and the winch 21 on the side wall of the support frame 20 starts to operate, driving the steel rope 23 wound on the concentrator 22 to be wound up and down. Under the pull of the winch 21, the steel rope 23 changes the direction of the force and reduces friction through the labor-saving wheel 24, and transmits the tension to the concentrator ring 25. The concentrator ring 25 is connected to the lifting frame 27 through the pull rope 26, thereby driving the lifting frame 27 to rise and fall vertically along the inner wall of the soaking tank 1. The outer wall of the steel rope 23 is rotatably connected to a labor-saving wheel 24. The end of the steel rope 23 away from the winch 21 is fixedly connected to a concentrating ring 25. The inner wall of the labor-saving wheel 24 is rotatably connected to the outer wall of the support frame 20. The outer wall of the concentrating ring 25 is symmetrically slidably connected to a pull rope 26. The end of the pull rope 26 away from the concentrating ring 25 is fixedly connected to a lifting frame 27. The outer wall of the lifting frame 27 is in contact with the inner wall of the soaking tank 1. Since the lifting frame 27 is tightly fitted to the inner wall of the soaking tank 1, the operator can precisely adjust the immersion depth and soaking time of the bamboo by controlling the rotation speed and retraction distance of the winch 21 according to the requirements of the bamboo impregnation process, so that the adhesive can fully penetrate the gaps between the bamboo fibers and enhance the bending resistance of the bamboo.

[0016] The extraction device 3 includes a placement frame 30. A limiting block 31 is symmetrically fixed to the outer wall of the lifting frame 27. A baffle 32 is slidably connected to the outer wall of the limiting block 31. A pin 33 is slidably connected to the inner wall of the limiting block 31 and the baffle 32. The outer wall of the placement frame 30 is slidably connected to the inner wall of the lifting frame 27. The processing object is placed on the inner wall of the placement frame 30. The outer wall of the pin 33 is slidably connected to the inner wall of the lifting frame 27. First, the operator places the bamboo material in the placement frame 30 of the extraction device 3. The placement frame 30 is fixed by the limiting block 31, the baffle 32 and the pin 33. The pin 33 passes through the limiting block 31 and the baffle 32 and is inserted into the corresponding hole in the inner wall of the lifting frame 27 to securely lock the placement frame 30 in the lifting frame 27 and prevent the bamboo material from shifting in subsequent operations.

[0017] During use, the lifting device 2 allows the bamboo plywood to be immersed in glue as a whole, and the extraction device 3 allows the bamboo plywood to be replaced quickly. First, the operator places the bamboo material into the placement frame 30 of the extraction device 3, and uses the limiting block 31, baffle 32 and pin 33 to fix the placement frame 30. The pin 33 passes through the limiting block 31 and baffle 32 and is inserted into the corresponding hole in the inner wall of the lifting frame 27 to securely lock the placement frame 30 in the lifting frame 27 and prevent the bamboo material from shifting in subsequent operations.

[0018] After the bamboo is fixed, the lifting device 2 is started. The winch 21 on the side wall of the support frame 20 starts to operate, driving the steel rope 23 wound on the concentrator 22 to be wound up and down. Under the pull of the winch 21, the steel rope 23 changes the direction of the force and reduces friction through the labor-saving wheel 24, and transmits the tension to the concentrator ring 25. The concentrator ring 25 is connected to the lifting frame 27 through the pull rope 26, thereby driving the lifting frame 27 to rise and fall vertically along the inner wall of the soaking tank 1. Because the lifting frame 27 is tightly fitted to the inner wall of the soaking tank 1, the operator can precisely adjust the immersion depth and soaking time of the bamboo by controlling the rotation speed and retraction distance of the winch 21 according to the requirements of the bamboo impregnation process, so that the adhesive can fully penetrate the gaps between the bamboo fibers and enhance the bending resistance of the bamboo.

[0019] After the resin impregnation is completed, the winch 21 reverses and pulls the steel rope 23 to smoothly lift the lifting frame 27 and the bamboo material from the soaking tank 1. After the lifting frame 27 is raised to a suitable height, the operator pulls out the pin 33, slides the baffle 32, and pulls the placement frame 30 out of the lifting frame 27 to take out the resin-impregnated bamboo material for subsequent drying, hot pressing and other processes.
