Description

Technical Field

[0001] This utility model relates to the field of wood processing technology, specifically to a glue-applying device for wood processing. Background Technology

[0002] Furniture manufacturing requires the use of a large amount of boards for production. Plywood is a three- or multi-layered board material made by rotary cutting logs into veneers or slicing timber into thin sheets and then gluing them together with adhesives. It usually uses an odd number of veneer layers and glues the adjacent veneer layers with the fiber directions perpendicular to each other. In the processing of plywood, glue application equipment is needed to apply glue.

[0003] A Chinese patent publication (CN219685991U) discloses a glue-applying device for wood processing, comprising a frame, a conveying system fixedly mounted on the frame for conveying wood boards, a column fixedly mounted on the upper surface of the frame with a vertical groove along the vertical direction, a glue-applying mechanism slidably mounted on the column and sliding along the column, and a vertical drive mechanism fixedly mounted on the frame to drive the glue-applying mechanism to slide. By combining the vertical drive mechanism and the glue-applying mechanism, the glue-applying roller can be adjusted in the vertical direction, adapting to thin wood boards of different thicknesses, thus improving the applicability and production efficiency of the device.

[0004] The above-mentioned device can apply glue to wood boards of different thicknesses. However, since the length of the glue roller is fixed, when applying glue to narrower wood boards, excess glue on the outer wall of the glue roller will remain on the conveyor, resulting in waste of glue and causing a certain degree of pollution to the conveyor. Therefore, it is necessary to propose a glue application device for wood board processing. Utility Model Content

[0005] The purpose of this invention is to provide a gluing device for wood processing, which can apply glue according to the length and width of the wood, thereby reducing material loss and contamination of the conveyor.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a glue-applying device for wood processing, comprising a roller conveyor, a bracket fixedly connected to the rear end of the roller conveyor, a U-shaped frame fixedly connected to the front end of the bracket, a lead screw rotatably connected inside the U-shaped frame, a slider threadedly connected to the outer wall of the lead screw, a support block fixedly connected to the right end of the slider, a first electric actuator installed at the upper end of the support block, the output end of the first electric actuator passing through the support block and fixedly connected to a drainage cavity, and a plurality of evenly distributed nozzles installed at the lower end of the drainage cavity;

[0007] The front and rear ends of the U-shaped frame are each equipped with a second electric push rod. The output end of the second electric push rod passes through the U-shaped frame and is fixedly connected to a vertical plate. Pressure sensors are installed on the opposite sides of the two vertical plates.

[0008] Limiting plates are fixedly connected to the lower end faces of both vertical plates, and the bottom end of the limiting plates abuts against the roller conveyor.

[0009] In order to drive the lead screw to rotate, as a preferred embodiment of the gluing device for wood processing according to this utility model, a motor is installed on the front end face of the U-shaped frame, and the output end of the motor passes through the U-shaped frame and is fixedly connected to the lead screw.

[0010] To support the brush, in a preferred embodiment of the gluing device for wood processing according to this utility model, the left end of the drainage cavity is fixedly connected to a mounting plate, and the upper end surface of the mounting plate is detachably connected to the brush by bolts.

[0011] To prevent the slider from rotating axially, in a preferred embodiment of the gluing device for wood processing according to this utility model, the upper end face of the slider abuts against the inner wall of the U-shaped frame.

[0012] To assist the roller conveyor in conveying wooden boards, as a preferred gluing device for wooden board processing according to this utility model, a support frame is fixedly connected to the upper end face of the front limiting plate. A third electric push rod is installed at the upper end of the support frame. The output end of the third electric push rod passes through the support frame and is fixedly connected to a drive frame. A roller is rotatably connected inside the drive frame.

[0013] In order to control the operation of the various components, as a preferred embodiment of the gluing device for wood processing according to this utility model, the front end of the roller conveyor is equipped with a controller.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] In use, this invention first activates two second electric actuators to drive the connected vertical plate and limiting plate to move, making the distance between the two limiting plates equal to the width of the wooden board. Then, the first electric actuator drives the drainage cavity downward, moving the drainage cavity and multiple nozzles to a position close to the roller conveyor. Next, by rotating the lead screw, the slider can be driven to reciprocate. Simultaneously, the slider reciprocates, driving the support block, drainage cavity, and multiple nozzles to reciprocate. During this process, the slider's reciprocating movement presses against two pressure sensors, which sense the slider's position and transmit the signal to the controller. The controller then controls the motor's forward and reverse rotation, allowing for adhesive application based on the length and width of the wooden board, reducing material waste and contamination of the conveyor.

Detailed Implementation

[0020] Please see Figures 1 to 3 A glue-applying device for wood processing includes a roller conveyor 1, a bracket 2 fixedly connected to the rear end of the roller conveyor 1, a U-shaped frame 3 fixedly connected to the front end of the bracket 2, a lead screw 10 rotatably connected inside the U-shaped frame 3, a slider 4 threadedly connected to the outer wall of the lead screw 10, a support block 5 fixedly connected to the right end of the slider 4, a first electric push rod 6 installed at the upper end of the support block 5, the output end of the first electric push rod 6 passing through the support block 5 and fixedly connected to a drainage cavity 7, and a plurality of evenly distributed nozzles 8 installed at the lower end of the drainage cavity 7.

[0021] The front and rear ends of the U-shaped frame 3 are equipped with second electric push rods 11. The output end of the second electric push rod 11 passes through the U-shaped frame 3 and is fixedly connected to a vertical plate 12. Pressure sensors 13 are installed on the opposite sides of the two vertical plates 12.

[0022] Limiting plates 16 are fixedly connected to the lower end faces of both vertical plates 12, and the bottom end of the limiting plates 16 abuts against the roller conveyor 1.

[0023] In this embodiment: during use, firstly, the two second electric actuators 11 are activated to drive the connected vertical plate 12 and limiting plate 16 to move, so that the distance between the two limiting plates 16 is equal to the width of the wooden board. Then, the first electric actuator 6 drives the drainage cavity 7 to move downward, moving the drainage cavity 7 and multiple nozzles 8 to a position close to the roller conveyor 1. Then, by rotating the lead screw 10, the slider 4 can be driven to move back and forth. While the slider 4 is moving back and forth, it drives the support block 5, the drainage cavity 7 and multiple nozzles 8 to move back and forth. During this process, when the slider 4 moves back and forth, it will squeeze the two pressure sensors 13 respectively. The two pressure sensors 13 can sense the movement position of the slider 4 and transmit the sensed signal to the controller. The controller controls the motor 9 to rotate forward and backward, so as to perform glue application on wooden boards of different widths and thicknesses.

[0024] As a technical optimization of this utility model, a motor 9 is installed on the front end face of the U-shaped frame 3, and the output end of the motor 9 passes through the U-shaped frame 3 and is fixedly connected to the lead screw 10.

[0025] In this embodiment, the lead screw 10 can be driven to rotate by the motor 9.

[0026] As a technical optimization of this utility model, the left end of the drainage cavity 7 is fixedly connected to the mounting plate 14, and the upper end surface of the mounting plate 14 is detachably connected to the brush 15 by bolts.

[0027] In this embodiment: the mounting plate 14 can be used to support the brush 15, and the brush 15 can be easily replaced by bolt connection.

[0028] As a technical optimization of this utility model, the upper end face of the slider 4 abuts against the inner wall of the U-shaped frame 3.

[0029] In this embodiment, the upper end face of the slider 4 abuts against the inner wall of the U-shaped frame 3, which prevents the slider 4 from rotating axially.

[0030] As a technical optimization of this utility model, a support frame 17 is fixedly connected to the upper end face of the front limiting plate 16. A third electric push rod 18 is installed at the upper end of the support frame 17. The output end of the third electric push rod 18 passes through the support frame 17 and is fixedly connected to a drive frame 19. A roller shaft 20 is rotatably connected inside the drive frame 19.

[0031] In this embodiment: the third electric actuator 18 can drive the drive frame 19 to move, thereby driving the roller 20 to move, so that the roller 20 abuts against the upper end of the wooden board on the upper end of the roller conveyor 1, which can assist in the conveying operation of the wooden board.

[0032] As a technical optimization of this utility model, a controller is installed at the front end of the roller conveyor 1.

[0033] In this embodiment, the first electric actuator 6, the second electric actuator 11, the pressure sensor 13, the third electric actuator 18, and the motor 9 are all electrically connected to the controller, which can control the operation of each component.

[0034] Working principle: When in use, firstly, the two second electric actuators 11 are activated to drive the vertical plate 12 and the limiting plate 16 connected to them to move, so that the distance between the two limiting plates 16 is equal to the width of the wooden board;

[0035] Place the wooden board above the right end of the roller conveyor 1 (between the two limit plates 16) and start the roller conveyor 1 to transport it. Then, drive the drainage chamber 7 downward through the first electric push rod 6 to move the drainage chamber 7 and multiple nozzles 8 to a position close to the roller conveyor 1, while the brush 15 comes into contact with the wooden board being transported.

[0036] Next, the motor 9 rotates the lead screw 10, which drives the slider 4 to move back and forth. While the slider 4 moves back and forth, it drives the support block 5, the drainage chamber 7 and multiple nozzles 8 to move back and forth. The upper end of the drainage chamber 7 is connected to the drainage pipe, and a delivery pump is installed on the outer wall of the drainage chamber 7. The glue delivery pipe of the external equipment is connected to the drainage pipe. The glue can be guided to the nozzles 8 through the delivery pump to spray glue on the wood board. At this time, the brush 15 moves back and forth with the drainage chamber 7, which can evenly spray glue on the wood board.

[0037] During this process, when the slider 4 moves back and forth, it will squeeze the two pressure sensors 13 respectively. The two pressure sensors 13 can sense the movement position of the slider 4. When the slider 4 squeezes one of the pressure sensors 13, the pressure sensor 13 transmits the sensed signal to the controller, which then causes the motor 9 to reverse, so as to apply glue to the wood boards of different widths and thicknesses.

[0038] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
