Description

Technical Field

[0001] This utility model belongs to the field of plywood processing technology, specifically referring to a plywood edge glue removal device for plywood production. Background Technology

[0002] Plywood is a sheet material made of three or more layers of veneer, which are rotary-cut from logs or sliced ​​from timber and then glued together with adhesive. It typically uses an odd number of veneer layers, with the grain direction of adjacent layers perpendicular to each other. Because adhesive is used for bonding, after compression, the adhesive will be squeezed from the gaps between the veneers towards the edges, so the adhesive on the edges of the board needs to be removed.

[0003] The plywood edge glue removal device described in announcement number CN222450728U includes a base, a plywood body, and a fixed frame. The upper surface of the base is connected to the fixed frame, and the upper surface of the fixed frame is provided with a glue removal component for removing edge glue from the plywood body. One end of a first electromagnetic slider is connected to a first drive motor, and one end of a second electromagnetic slider is connected to a second drive motor, enabling the movement of a grinding blade within the fixed frame to remove the edge glue from the plywood. Existing edge glue removal devices use a rotating blade to move around the perimeter of the plywood to grind the edge glue. After grinding, the edge glue adheres to the surface of the grinding blade, which can easily affect the contact between the blade and the plywood, thus affecting the grinding effect.

[0004] Therefore, there is an urgent need for a plywood edge glue removal device to solve the above problems. Utility Model Content

[0005] In view of the above situation and to overcome the defects of the prior art, the purpose of this utility model is to provide a plywood edge glue removal device for plywood production, so as to at least partially solve the problems mentioned in the background art.

[0006] The technical solution adopted by this utility model is as follows: A plywood edge glue removal device for plywood production is proposed, including a conveying section, which includes two conveying tables arranged in an L-shape, the two conveying tables being used to convey the plywood in a right-angle path; a grinding section, which includes grinding rollers arranged on both sides along the conveying direction of the plywood, the sidewalls of the grinding rollers having a plurality of scraping grooves along their rotation axis, the rotation axis of the grinding rollers being inclined to the conveying direction of the plywood; and a transmission section, which includes a moving plate arranged along the conveying direction of the plywood, a fixing mechanism for use with the conveying tables is provided below the moving plate, the fixing mechanism being configured to adhere the plywood to the surface of the conveying table along the conveying direction.

[0015] The accompanying drawings are provided to further understand the embodiments and form part of the specification. They are used together with the embodiments for explanation and do not constitute a limitation on the embodiments. Detailed Implementation

[0016] The technical solutions in the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection.

[0017] As mentioned above, the existing technology for scraping off the edge glue of plywood has the drawback that the edge glue adheres to the surface of the grinding head after grinding, which can easily affect the contact between the grinding head and the plywood and affect the grinding effect of the edge glue.

[0018] To address this issue, this utility model provides a plywood edge glue removal device for plywood production. The device utilizes a rotating grinding roller 201. As the grinding roller 201 rotates, the protrusions formed between the scraping grooves 202 on its sidewall scrape away the plywood edges one by one. The scraped-off edge glue and other debris accumulate inside the scraping grooves 202 and are pushed upwards and outwards with the rotation of the grinding roller 201, achieving self-cleaning and ensuring the completeness of edge glue removal.

[0019] like Figures 1-4As shown, this utility model embodiment provides a plywood edge glue removal device, particularly a plywood edge glue removal device for plywood production, including a conveying unit 1, a grinding unit 2, a transmission unit 3, and a fixing mechanism 4. The conveying unit 1 includes two L-shaped conveyor tables 101. This L-shaped arrangement allows the plywood to be transported from one conveyor table 101, where, for example, the glue on both sides of the plywood is removed, and then transferred to the second conveyor table 101. As the plywood is transported on the second conveyor table 101, the front and back sides of the plywood are also ground and glue removed, thus performing glue removal on all four sides of the plywood. The grinding unit 2 includes grinding rollers 201 disposed on both sides along the conveying direction of the conveyor table 101. The rotation axis of the grinding rollers 201 is not vertical, but tilted slightly to both sides. Furthermore, one side of the rotation axis of the two grinding rollers 201 tilts forward, while the other side tilts backward, resulting in different tilts on the two sides. Several evenly distributed scraping grooves 202 are opened on the side wall of the grinding roller 201. The raised positions formed between the scraping grooves 202 scrape off the glue on the edge of the plywood. The scraped glue and other debris are squeezed out from the scraping grooves 202 and squeezed upward along the edge of the grooves.

[0020] As the plywood moves, the grinding rollers 201 rotate, and the protrusions formed between the scraping channels 202 scrape off the adhesive from the plywood edges one by one as the grinding rollers 201 rotate. As the scraped adhesive enters the scraping channels 202, it pushes and extrudes the adhesive residue from the plywood edges upwards. To ensure that the grinding rollers 201 can rotate and grind the plywood as it passes between them... The transmission unit 3 includes a movable plate 301, which moves along the plywood conveying direction and is positioned above the conveying table 101. The movable plate 301 has a trapezoidal cross-section. Mounting frames 5 are mounted on the conveying table 101, and each mounting frame 5 contains a lead screw 7. A T-shaped drive block 6 is also located within the mounting frame 5. The drive block 6 is fixedly connected to the upper surface of the movable plate 301, and the drive block 6 is threadedly connected to the lead screw 7. A motor at one end of the mounting frame 5 drives the lead screw 7, causing the drive block 6 to move along the plywood conveying direction within the mounting frame 5. Helical toothed plates 11 are fixedly connected to both inclined surfaces of the movable plate 301. Support rods 9 are fixedly connected to both sides of the mounting frame 5 along the plywood moving direction. The shaft of the grinding roller 201 is rotatably connected to the support rods 9. A gear 10 is fixedly connected to the top of the shaft on each of the grinding rollers 201. The gear 10 meshes with the helical tooth plate 11. After the middle moving plate 301 passes between the two grinding rollers 201, the two grinding rollers 201 move on the moving plate 301. The helical tooth plate 11 moves the gear 10, and the two grinding rollers 201 move in opposite directions.

[0021] To ensure that the drive block 6 moves only inside the mounting frame 5 and does not rotate with the lead screw 7, guide rods 8 are provided on both sides of the lead screw 7 on the mounting frame 5. The guide rods 8 pass through the drive block 6, and the drive block 6 slides on the guide rods 8. To fix the plywood, a fixing mechanism 4 is provided below the drive block 6. The fixing mechanism 4 may include a lifting cylinder 401 and a pressure plate 402 fixedly connected to the lower telescopic end of the lifting cylinder 401. Guide rods are fixedly connected to the upper end of the pressure plate 402 at both the front and rear. The guide rods pass through the moving plate 301, ensuring that the pressure plate 402 moves up and down below the moving plate 301. The pressure plate 402 presses the plywood onto the conveyor table 101, preventing the plywood from shaking up and down when the edge glue is removed.
