Description

Technical Field

[0001] This utility model relates to the field of wood processing technology, and in particular to a flipping conveyor device for wood production and processing. Background Technology

[0002] Wood boards are boards made from whole pieces of wood. After initial production, the wood needs to undergo surface processing, such as polishing, spraying, coating, waxing, etc.

[0003] In traditional wood surface processing, the wood is usually laid flat, and one side is processed first. Then, the wood is turned over manually, and the other side is processed, thus achieving the effect of processing both sides of the wood.

[0004] According to Chinese Patent Publication No. CN223315857U, a flipping and conveying device for wood production and processing is proposed. Through the arrangement of side-flipping components, guide plates, and a drive assembly, when a wooden board enters the area of ​​the mounting plate under the conveyor belt, the drive assembly drives multiple side-flipping components to move. These components work together to push the wooden board from one side towards the guide plate. After the wooden board contacts the lower end of the guide wall of the guide plate, it is guided upwards by the arc-shaped surface at the lower end of the guide wall. At this time, the multiple side-flipping components continue to push the wooden board, causing one side of the board to continuously rise under the action of the guide wall, eventually entering the upper arc-shaped surface area of ​​the guide wall. Guided by the upper arc-shaped surface of the guide wall, the board tilts to the other side, ultimately achieving a flipping effect. It then continues to be conveyed under the action of another belt conveyor, thus achieving the purpose of flipping and conveying.

[0005] According to existing technology, when a wooden board is flipped by pushing, although two guide plates are provided, the board may still fall off due to sliding or excessive movement during the flipping process. Therefore, a flipping and conveying device for wood production and processing is proposed to solve the above-mentioned technical problems. Utility Model Content

Two guide rods extending to the outside of the U-shaped plate are installed on the outside of the U-shaped frame, and both guide rods are slidably connected to the U-shaped plate.

[0011] Preferably, the abutting mechanism includes multiple rotating shafts rotatably connected to the rear side wall of the U-shaped frame cavity and extending to its front side. Abutting rollers are mounted on the outer side of the rotating shafts, and a transmission assembly is provided on the front side of the U-shaped frame for driving the multiple abutting rollers to rotate.

It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this utility model.

For example, "connected" can be a fixed connection, such as welding, riveting, or bonding; it can also be a detachable connection, such as threaded connection, keyed connection, or pin connection; or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; or it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0024] like Figure 1-5 As shown, the present invention proposes a wood production and processing turning conveyor device, which mainly consists of two horizontally arranged conveyor belts 1 and a turning station located between them.

[0025] like Figure 1-3 As shown, in this embodiment, the core support structure of the flipping station is a horizontal plate 2, which is fixed at both ends between the frames of the two conveyor belts 1 by bolts. A vertical plate 3 is welded on the horizontal plate 2. A rotating disk 4 is on the front of the vertical plate 3, and the drive mechanism 5 is set on the back of the vertical plate 3. The drive mechanism 5 includes a T-shaped groove 51 opened on the front of the vertical plate 3. A matching T-shaped block 52 is fixed on the back of the rotating disk 4. The T-shaped block 52 is installed in the T-shaped groove 51 by bearings to achieve smooth rotation. A self-locking reduction motor 53 is installed on the back of the vertical plate 3 by a motor base. Its output shaft passes through the vertical plate 3 and is connected to the center of the T-shaped block 52 to provide rotational power for the rotating disk 4 and has a self-locking function.

[0026] like Figure 4As shown, in this embodiment, a U-shaped plate 6 is fixed on the front of the rotating disk 4, and two U-shaped frames 7 are symmetrically arranged on the inner side of the U-shaped plate 6. At the same time, a pushing mechanism 8 is provided on the outer side of the U-shaped plate 6. The pushing mechanism 8 includes an electric push rod 81 installed on the outer side of the U-shaped plate 6, whose piston rod extends into the U-shaped plate 6 and connects with the U-shaped frame 7. Two guide rods 82 extending to the outer side of the U-shaped frame 7 are installed on the outer side of the U-shaped frame 7. Both guide rods 82 are slidably connected to the U-shaped plate 6 to ensure the stability of the U-shaped frame 7 when it moves. When the two electric push rods 81 are activated, the piston rods of the two electric push rods 81 will drive the two U-shaped frames 7 to move to the opposite side or the opposite side, respectively.

[0027] like Figure 4-5 As shown in this embodiment, each U-shaped frame 7 is provided with an abutment mechanism 9. The abutment mechanism 9 includes multiple rotating shafts 91 mounted on the U-shaped frame 7 via bearing seats. Each rotating shaft 91 is equipped with an abutment roller 92. A transmission assembly 93 is provided on the front side of the U-shaped frame 7 to drive the multiple abutment rollers 92 to rotate synchronously. The transmission assembly 93 includes a fixed box mounted on the front side of the U-shaped frame 7, which encloses the sprocket and chain inside. A servo reduction motor is mounted on the fixed box to drive one of the rotating shafts 91, thereby driving all the abutment rollers 92 to rotate synchronously through chain drive.

[0028] The top horizontal position of the lower abutment roller 92 corresponds to the belt of the conveyor belt 1, ensuring that the plate being transported on the left conveyor belt 1 can stably enter the top of the lower abutment roller 92, and the plate is supported by the lower abutment roller 92.

[0029] Specifically, during the transport and flipping of the sheet material, the sheet material conveyed on the left conveyor belt 1 is transported to the top of the lower abutment roller 92. Then, two electric push rods 81 are activated, which drive the two U-shaped frames 7 to move to opposite sides. The two U-shaped frames 7 will drive the upper and lower abutment rollers 92 to move to opposite sides until the upper and lower abutment rollers 92 are stably abutting the top and bottom of the sheet material, respectively. At this time, the self-locking reduction motor 53 can be activated to make the rotating disk 4 rotate. Under the action of the U-shaped plate 6 and the U-shaped frame 7, the sheet material will be flipped through the abutment rollers 92. Anti-slip rubber pads are installed on the outer side of the abutment rollers 92 to increase the friction between the abutment rollers 92 and the sheet material, and to prevent the sheet material from separating from the abutment rollers 92 during flipping.

[0030] The self-locking geared motor 53 is a stepper motor. Each time it starts, it causes the plate and the abutment roller 92 to rotate 180°. After the plate rotates, the two electric push rods 81 are activated in the opposite direction, causing the upper and lower abutment rollers 92 to move to opposite sides. This allows the top horizontal position of the lower abutment roller 92 to correspond to the belt of the conveyor belt 1. At this time, the lower servo geared motor is activated, causing the lower abutment roller 92 to rotate. The lower abutment roller 92 needs to rotate clockwise, which can drive the plate to move towards the right conveyor belt 1, thus transporting the plate onto the right conveyor belt 1. The plate continues to be transported on the right side. Meanwhile, the left conveyor belt 1 can transport the plate to the lower abutment roller 92 again. Repeating the above operation can flip the plate again.

[0031] It should be noted that a PCL controller is installed on the base of the conveyor belt 1. The self-locking geared motor 53, the electric push rod 81 and the servo geared motor are all electrically connected to the PCL controller. The PCL controller can control the self-locking geared motor 53, the electric push rod 81 and the servo geared motor.

[0032] The U-shaped plate 6 has an infrared sensor installed on the front side wall of its inner cavity. The infrared sensor can detect the position of the plate. When the plate moves to the point where its right end corresponds to the rightmost abutment roller 92 below, it can transmit a signal to the electric push rod 81. By activating the electric push rod 81, the plate can be automatically clamped and fixed.

[0033] The self-locking geared motor 53, the electric push rod 81, and the servo geared motor are all controlled by the PCL controller through programming. The two electric push rods 81 adopt synchronous control technology, so that the two electric push rods 81 move synchronously. The synchronous control technology is existing technology and will not be described in detail in this application.

[0034] When flipping the board, the two servo geared motors alternately position themselves below. After flipping the board, simply start the lower servo geared motor to make it rotate clockwise.

[0035] Working principle: In this wood processing and turning conveyor, the wood is fed from the left conveyor belt 1 to the top of the lower abutment roller 92. When its right end aligns with the rightmost abutment roller 92, the PCL controller receives a signal and activates two electric push rods 81, pushing two U-shaped frames 7 to move towards each other until the abutment rollers 92 on both sides firmly contact and press against the wood surface. Then, the self-locking reduction motor 53 starts, driving the rotating disk 4 and the board it holds to rotate 180 degrees, turning the wood over. After turning, the two electric push rods 81 are activated in the opposite direction to release the wood, so that the top of the lower abutment roller 92 is aligned with the belt of the conveyor belt 1. Finally, the servo reduction motor is activated, and the rotation of the abutment roller 92 drives the board to move to the right, so that it falls onto the right conveyor belt 1 and is sent away, completing one work cycle. The above operation is then repeated to continuously transport and turn the board.

[0036] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
