Description

Technical Field

[0001] This utility model relates to the field of wood processing technology, and in particular to a glue application device for a wood edge banding machine. Background Technology

[0002] In modern furniture manufacturing and wood processing, edge banding is a crucial process that not only enhances the aesthetics of the product but also effectively protects the edges of the boards from moisture and physical damage. Traditional edge banding typically involves the following steps: first, applying a layer of glue to the side of the board to be edge banded; then, attaching the banding strip to the edge of the board; and finally, using a clamping device to firmly adhere the strip to the board.

[0003] However, existing wood panel edge banding equipment and technologies have the following shortcomings:

[0004] 1. Poor adhesion: Traditional gluing devices generally apply glue directly to the surface of untreated wood boards. Due to the unevenness or dirt on the surface of the wood boards, the glue cannot be evenly distributed, resulting in a weak bond between the wrapping strip and the wood board. This affects the adhesion strength between the wrapping strip and the wood board, making it easy for the glue to come off or loosen, thus affecting product quality.

[0005] 2. Glue Overflow Issue: During the bonding process of the wrapping strips, a certain amount of glue overflow is unavoidable. If it is not cleaned up in time, the glue will gradually solidify in the air, forming residues that are difficult to remove. This not only affects the appearance of the product but also increases the workload and cost of subsequent cleaning.

[0006] To address the aforementioned issues, we propose a glue applicator for a wood panel edge banding machine. This applicator can improve the bonding effect while effectively solving the problem of glue overflow. Utility Model Content

Clamping wheels are threadedly connected to the adjusting rods. The mounting plate is provided with a pretreatment component for pre-treating the wood before glue application and edge banding, and a cleaning component package for cleaning up excess glue after glue application and edge banding.

[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. 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.

[0023] Example 1: A glue applicator for a wood panel edge banding machine, such as... Figures 1-6As shown, the assembly includes a mounting plate 1, a lifting handle 2, a control box 3, a glue storage tank 4, a glue dispensing frame 5, a glue brushing roller 6, a conveyor plate 7, guide rods 71, a limit plate 72, a threaded rod 73, a pressing roller 8, a guide plate 9, a clamping wheel 10, an adjusting rod 101, a pretreatment component, and a cleaning component. The lifting handle 2 is fixedly connected to the upper side of the mounting plate 1, the control box 3 is fixedly connected to the rear side of the mounting plate 1, the glue storage tank 4 is fixedly connected to the front left side of the mounting plate 1, the glue dispensing frame 5 is connected to the lower side of the glue storage tank 4, and the glue brushing roller 6 is rotatably connected inside the glue dispensing frame 5. The front right side of the mounting plate 1 is fixedly connected to the inclined conveyor plate 7, and two guide rods 71 ​​are fixedly connected to the conveyor plate 7. A limit plate is slidably connected between the two guide rods 71. 72. A threaded rod 73 is rotatably connected to the middle of the conveyor plate 7. The threaded rod 73 is connected to the limiting plate 72 by a thread. A pressing roller 8 is rotatably connected to the lower right front side of the mounting plate 1. A guide plate 9 is fixedly connected to the lower middle front side of the mounting plate 1. The guide plate 9 is arc-shaped and is used to convey the edge banding strip to the area below the pressing roller 8. Adjusting rods 101 are rotatably connected to the left and right sides of the lower part of the mounting plate 1. Clamping wheels 10 are threadedly connected to the adjusting rods 101. The wheels of the clamping wheels 10 are made of rubber and are used to increase friction to grip the wooden board. The mounting plate 1 is provided with a pretreatment component for pre-treating the wooden board before applying glue and edge banding. The mounting plate 1 is provided with a cleaning component package for cleaning up excess glue after applying glue and edge banding.

[0024] When using this device, the operator inserts one end of the edge banding strip into the conveyor plate 7, then guides it around the pressure roller 8 via the guide plate 9. The position of the limiting plate 72 is adjusted by rotating the threaded rod 73, thus limiting the position of the edge banding strip and preventing it from shifting. The operator then holds the lifting handle 2 and moves the device to the upper side of the wooden board where edge banding is needed, so that the lower part of the mounting plate 1 is positioned behind the board and the clamping wheel 10 is positioned in front of the board. Rotating the adjusting rod 101 allows the clamping wheel 10 to be pressed tightly against the board. At this point, the operator controls the device to move along the wooden board... When the device moves to the left, the pretreatment component first sands the upper side of the wood board that needs to be edge-banded. Then, the glue roller 6 rotates and comes into contact with the glue in the glue dispensing frame 5 and picks up some glue. After that, the glue roller 6 continues to rotate and can apply the picked-up glue to the upper side of the wood board. During this period, the glue in the glue storage tank 4 will continuously flow into the glue dispensing frame 5 to replenish the glue. The pressing roller 8 is behind the glue roller 6 and presses the edge banding strip firmly onto the upper side of the wood board. After the edge banding strip is bonded, the cleaning component cleans up the excess glue on the front and back sides of the wood board.

[0025] Example 2: Based on Example 1, such as Figure 1 , Figure 3 and Figure 4As shown, the pretreatment assembly includes a fixing block 11, a motor 12, a grinding wheel 13, a brush plate 14, and a suction port 15. The fixing block 11 is fixedly connected to the lower left side of the mounting plate 1. The motor 12 is fixedly connected to the fixing block 11. The grinding wheel 13 is fixedly connected to the output shaft of the motor 12. The brush plate 14 is fixedly connected to the fixing block 11. The suction port 15 is fixedly connected to the fixing block 11 and is connected to an external vacuum cleaner. The external vacuum cleaner connected to the suction port 15 and the motor 12 are connected to the control box 3 via... Electrically connected, motor 12 is specifically a series-wound motor, which can provide high torque at low speeds, making it ideal for grinding tasks requiring high torque output. It has good speed regulation performance and can automatically adjust the speed according to the load, maintaining constant power output during grinding. The control box 3 adopts a PLC control system, which can adjust the operating speed of the external vacuum cleaner connected to motor 12 and suction port 15 through preset programs, and control the opening and closing of the external vacuum cleaner connected to motor 12 and suction port 15 through its own buttons.

[0026] When controlling the device to move on the wooden board, the operator controls the operation of the external vacuuming equipment connected to the motor 12 and the suction port 15 through the control box 3. The operation of the motor 12 drives the grinding wheel 13 to rotate. The rotation of the grinding wheel 13 can first perform pre-treatment grinding on the upper side of the wooden board that needs to be edge-banded, and then grind the uneven parts or dirt on the wooden board. The dust and debris from grinding are brushed clean by the brush plate 14 and then sucked in through the suction port 15 to prevent dust from remaining on the wooden board and affecting the bonding force between the edge banding strip and the wooden board.

[0027] like Figure 1 , Figure 5 and Figure 6 As shown, the cleaning assembly includes a horizontal plate 16, a scraper 17, a top block 18, a torsion spring 19, a lifting block 20, a guide rod 21, and a telescopic spring 22. The horizontal plate 16 is fixedly connected to the lower right side of the mounting plate 1. The scraper 17 is rotatably connected to both the front and rear parts of the horizontal plate 16. The top block 18 is fixedly connected to the upper side of the scraper 17. The torsion spring 19 is connected between the top block 18 and the horizontal plate 16. The guide rod 21 is fixedly connected to both the front and rear parts of the upper side of the horizontal plate 16. The lifting block 20 is slidably connected between the front and rear guide rods 21. The front and rear ends of the upper part of the lifting block 20 are provided with wedge-shaped protrusions. The top block 18 is provided with a protruding rod. The wedge-shaped protrusions and the protruding rods are pressed together. The telescopic spring 22 is connected between the lifting block 20 and the guide rod 21.

[0028] When the device is placed on the upper side of the wooden board, the upper side of the board will press the lifting block 20 to slide upward, causing the telescopic spring 22 to deform. The lifting block 20 slides upward and presses the convex rod through the wedge-shaped protrusion to rotate, which in turn causes the top block 18 to drive the scraper 17 to rotate. The torsion spring 19 deforms. After the scraper 17 rotates, the left end of the scraper 17 is in contact with the front and rear sides of the wooden board. When the device moves to the left to seal the edge, the scraper 17 scrapes off the glue overflowing from the sealing strip pressed by the pressing roller 8 at the rear. When the device is removed from the wooden board, the lifting block 20 is no longer pressed by the wooden board. At this time, under the action of the telescopic spring 22 to reset, the lifting block 20 slides downward to reset. The lifting block 20 slides downward and no longer presses the convex rod. Under the action of the torsion spring 19 to reset, the scraper 17 reverses and resets.

Furthermore, it should be understood that after reading the teachings of this invention, those skilled in the art can make various alterations or modifications to the invention, and these equivalent forms also fall within the scope defined by the appended claims.
