Description

Technical Field

[0001] This utility model relates to the technical field of board edge glue removal devices, and in particular to a board edge glue removal device for bamboo and wood plywood production. Background Technology

[0002] Bamboo and wood plywood is a composite board made from bamboo and wood as the main raw materials through a gluing process. However, the extrusion during the gluing process can cause excess glue to overflow from the sides of the plywood. The overflowing glue directly affects the appearance, processing performance and product quality of the plywood. Therefore, it is necessary to further treat the overflowing glue on the edges of the plywood using an edge glue removal device.

[0003] The plywood edge glue removal device is an automated piece of equipment used in plywood production lines. It mainly consists of a conveying system, sanding rollers, a pressing mechanism, and a control system. During use, the plywood is smoothly fed in via a conveyor belt. High-speed rotating carbide blades precisely cut or sanding rollers grind away excess glue and burrs from the edges of the plywood, ensuring smooth and flat edges. The device can adjust the cutting depth and feeding speed via PLC to adapt to plywood of different thicknesses and glue types, improving processing efficiency and reducing manual trimming costs. It is widely used in subsequent plywood processing steps.

[0004] Traditional board edge glue removal devices lack dust recovery components during sanding roller operations, causing glue powder and wood dust to splash and spread during high-speed operation, resulting in work environment pollution and the generation of a large amount of suspended particulate matter. Workers exposed to such a high-dust environment for a long time are very likely to inhale fine particulate matter through their respiratory system, posing a potential threat to the lung health of operators and posing a significant occupational safety hazard. Utility Model Content

[0005] The purpose of this invention is to solve the problem of a large amount of glue powder and wood powder generated during the operation of sanding rollers in the prior art, and to propose a glue removal device for the edge of bamboo plywood production.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A device for removing adhesive from the edge of bamboo plywood during production includes a sealed cover fixedly installed outside a sanding roller. A filter screen is fixedly installed inside the sealed cover, and a processing channel is provided on the sealed cover. The filter screen divides the interior of the sealed cover into a coarse filtration zone and a fine filtration zone. A detachable collection box is movably installed on the sealed cover, and a recovery zone is formed between the filter screen and the collection box. When the sanding roller is working, larger waste materials are intercepted by the filter screen and fall into the collection box through the recovery zone. A fine filter element is provided in the fine filtration zone for filtering powdery waste materials.

[0008] To facilitate the filtration of powdery waste, preferably, the fine filter element includes a filter cloth fixedly installed in the fine filtration zone, and a guide plate is fixedly installed on the filter cloth. When dust flows to the top of the filter cloth, the filter cloth intercepts the powdery waste.

[0009] To guide the flow of powdery waste, guide plates are arranged at equal intervals in the fine filtration zone, and the angle between the guide plates and the filter cloth is 30-45 degrees. When the dust passes through the guide plates, the dust flows steadily onto the filter cloth.

[0010] To facilitate the recycling of powdery waste, a recycling pipe is fixedly installed on the collection box, and the collection box is connected to the fine filtration zone through the recycling pipe.

[0011] To facilitate the formation of a negative pressure environment inside the sealing cover, preferably, a connecting pipe is fixedly installed on the sealing cover for connecting the connecting pipe to an external negative pressure machine.

[0012] To facilitate the falling of granular waste into the collection box, the recycling area is preferably set as an inclined plate with an inclination angle of 40-60 degrees.

[0013] Compared with the prior art, this utility model provides a device for removing glue from the edge of bamboo plywood during production, which has the following advantages:

[0014] 1. This bamboo and wood plywood production edge glue removal device uses a sealed cover and filter screen to retain the waste material from sanding rollers inside the sealed cover, while intercepting large particles of waste material and directing them into the collection box. This avoids the problem of large amounts of powder splashing during sanding roller operation and polluting the working environment, while also improving the safety of workers and preventing them from inhaling dust and affecting their health.

[0015] 2. The board edge glue removal device for bamboo and wood plywood production can effectively intercept powdery waste through the interception cloth set in the fine filter element, thereby reducing the dust splashed during sanding roller operation, further improving the safety of the device during operation, and effectively preventing a large amount of dust from splashing into the working environment.

[0016] The parts of this device not described herein are the same as or can be implemented using existing technologies. This utility model effectively reduces the dust generated during the operation of the sanding roller by using a combination of a sealing cover, a filter screen, and a fine filter element, preventing excessive dust from splashing and polluting the working environment, while also improving the safety of the workers.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings.

[0024] Example:

[0025] Reference Figures 1-4A device for removing edge glue in bamboo plywood production includes a sealing cover 1 fixedly installed outside a sanding roller. A connecting pipe 8 is fixedly installed on the sealing cover 1 for connecting to an external negative pressure unit, allowing airflow inside the sealing cover 1 to draw dust generated by the sanding roller into the sealing cover 1. A filter screen 2 is fixedly installed inside the sealing cover 1, and a processing channel 9 is provided on the sealing cover 1. The filter screen 2 divides the interior of the sealing cover 1 into a coarse filtration zone 1a and a fine filtration zone 1b. Through the dual filtration of the coarse filtration zone 1a and the fine filtration zone 1b, the dust splashed during sanding roller operation is effectively prevented from floating in the air. A detachable collection device is movably installed on the sealing cover 1. The collection box 3 has a "T"-shaped guide strip on top, allowing it to slide freely within the guide groove of the sealing cover 1. This facilitates disassembly and unified cleaning of the collected waste. The filter screen 2 and the collection box 3 form a recycling area 1c. When the sanding roller is working, larger waste materials are intercepted by the filter screen 2 and fall into the collection box 3 through the recycling area 1c, effectively preventing large particles from being thrown out and reducing the amount of waste particles in the working environment. The fine filtration area 1b is equipped with a fine filter element to filter powdery waste, further reducing the amount of powdery waste generated during the operation of the sanding roller and preventing dust pollution in the working environment.

[0026] Specifically, the sealing cover 1, together with the filter screen 2, retains the waste material from the sanding roller inside the sealing cover 1, while intercepting large particles of waste material and directing them into the collection box 3. This avoids the problem of a large amount of powder splashing during the operation of the sanding roller, which would pollute the working environment. At the same time, it improves the safety of the workers and prevents them from inhaling dust and affecting their health.

[0027] The fine filter element includes a filter cloth 5 fixedly installed in the fine filter zone 1b. A guide plate 6 is fixedly installed on the filter cloth 5. The guide plate 6 is set as a 45-degree inclined plate. The inclined angle allows dust to fall freely. When the dust flows above the filter cloth 5, the filter cloth 5 intercepts the dust-like waste material, effectively preventing the dust-like waste material from spreading into the working environment.

[0028] Guide plates 4 are arranged at equal intervals in the fine filtration zone 1b, and the angle between the guide plates 4 and the filter cloth 5 is 30-45 degrees. When dust passes through the guide plates 4, the dust flows stably onto the filter cloth 5, thereby improving the filtration effect of the filter cloth 5 and preventing the dust from flowing unstablely in the fine filtration zone 1b, which would lead to a decrease in filtration effect.

[0029] A recycling pipe 7 is fixedly installed on the collection box 3. The collection box 3 is connected to the fine filtration zone 1b through the recycling pipe 7. When the filter cloth 5 intercepts dust, the dust falls and is guided by the guide plate 6 into the recycling pipe 7, which facilitates the recycling of the dusty waste intercepted in the fine filtration zone 1b into the collection box 3.

[0030] The recycling area 1c is set as an inclined plate with an inclination angle of 40-60 degrees. The preferred inclination angle of the inclined plate in this application is 45 degrees, which makes it easier for the particulate waste intercepted by the filter screen 2 to slide down into the collection box 3 through the inclined plate, so as to facilitate the subsequent unified cleaning of the waste in the collection box 3.

[0031] In this invention, the external negative pressure machine is first started. The negative pressure inside the sealing cover 1 is generated by the operation of the negative pressure machine. When the plywood enters through the processing channel 9 and comes into contact with the sanding roller for sanding, the generated glue powder and wood powder are sucked into the sealing cover 1. Then the dust flows to the coarse filtration zone 1a and passes through the filter screen 2. The filter screen 2 intercepts the large dust particles and causes them to fall into the recovery zone 1c. The large dust particles are further guided by the inclined plate to fall into the collection box 3. Then some fine dust enters the fine filtration zone 1b. The guide plate 4 first guides the dust to change the direction of the dust flow. When the dust comes into contact with the filter cloth 5, the filter cloth 5 intercepts the fine dust. The intercepted dust is guided by the guide plate 6 to the recovery pipe 7 and then enters the collection box 3 through the recovery pipe 7. The collection box 3 can then uniformly process the dust intercepted in the sealing cover 1. Then the air that has been double filtered is discharged from the exhaust port of the negative pressure machine through the connecting pipe 8. This can avoid a lot of dust splashing and remaining in the working environment and improve the safety of the workers.

[0032] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
