Description

Technical Field

[0001] The utility model relates to the field of wood ring cutting machinery, in particular to a wood ring cutting device. Background Art

[0002] The application fields of wood are very wide, such as construction, ships, sports equipment, etc. Solid wood is processed from logs, and logs can only be processed into wood after cutting, shaping, etc.

[0003] The prior art discloses a circular timber ring cutting device for wood processing machinery with application number: CN202320662996.7. The stepper motor drives the threaded sleeve to rotate, so that the screw drives the tool to move up and down in the inner cavity of the threaded sleeve. The height of the tool can be raised and lowered, which is convenient for cutting wood at different depths. At the same time, the servo motor drives the threaded rod to rotate, so that the mounting block moves left and right on the surface of the threaded rod, and the position of the tool is adjusted to facilitate cutting wood from different positions. The driving motor drives the first rotating shaft and the second rotating shaft to rotate synchronously through the pulley and the transmission belt, which is convenient for rotating the wood on the top of the drum, and then cooperates with the limiting roller to limit the wood to ensure stable rotation of the wood. Then the clamping plate can limit the position of the wood to prevent the wood from moving left and right, which causes the tool and wood to be stuck, and facilitates rapid ring cutting of circular timber.

[0004] However, this existing technology can only perform circular cutting on wood with regular shapes. Since the up and down movement of the tool is controlled by a stepper motor, when irregular protrusions are encountered during the circular cutting of the wood, the height of the tool is not adjusted in time, resulting in the wood and the tool being stuck, thereby damaging the equipment and reducing the efficiency of the wood circular cutting. Utility Model Content

The height of the roller can be adjusted according to actual usage, so that the roller can better perform ring cutting on the wood, which can effectively improve the ring cutting efficiency.

[0006] The technical solution of the utility model is as follows:

[0007] A wood ring cutting device, comprising:

[0008] The rotating part includes a fixed frame, the inner cavity of the fixed frame is rotatably connected to two rollers through bearings;

[0009] A ring cutting portion is mounted on the rotating portion, the ring cutting portion includes a support box, a support frame is provided on the top of the support box, an electric telescopic rod is installed on the support frame, the electric telescopic rod passes through the interior of the support box, and the piston end of the electric telescopic rod is connected to the ring cutting device;

[0012] The working principle of the above technical solution is as follows:

[0013] When the wood ring cutting device of the present invention is used, the user places the wood to be cut between two rollers. The rotation of the rollers drives the wood to rotate, and the driving component drives the push rod to drive the wood to move toward the ring cutting part. The electric telescopic rod on the ring cutting part adjusts the height of the ring cutting device according to the diameter of the wood. The wood enters the ring cutting part, and the ring cutting device ring cuts the moving and rotating wood, thereby realizing ring cutting processing of different positions of the wood.

The output end of the motor passes through the side wall of the supporting part to the fixed box, and the two rollers pass through the side wall of the fixed frame to the fixed box. The two rollers are driven by the motor to roll in the same direction through a synchronous pulley. The motor drives the rollers to rotate in the same direction, so that the rollers drive the wood, which facilitates the rapid rotation of the wood and facilitates the ring cutting device to ring cut the rotating wood.

The infrared height gauge can effectively measure the wood diameter and work in conjunction with the PLC controller to mobilize the electric telescopic rod to extend and retract, thereby completing the ring cutting of the wood and improving the automation level of the equipment.

[0020] In a further technical solution, the driving assembly includes a servo motor fixed to the left side of the fixed frame, the output shaft of the servo motor is fixed with a threaded rod, the threaded rod is rotatably connected to the inner cavity of the fixed frame through a bearing, and the push rod is movably connected to the surface of the threaded rod through a threaded sleeve. The threaded rod is driven to rotate by the servo motor, and the push rod can move left and right at a uniform speed on the surface of the threaded rod with the cooperation of the threaded sleeve, thereby pushing the wood forward and realizing ring cutting of different positions of the wood.

The electric telescopic rod 21 on the ring cutting part adjusts the height of the ring cutting device according to the diameter of the wood. The wood enters the ring cutting part, and the ring cutting device ring cuts the moving and rotating wood, thereby realizing ring cutting processing of different positions of the wood.

[0043] The utility model is suitable for ring cutting of wood with different diameters, can ring cut the wood at different positions, and can complete the ring cutting work of the wood within one transportation process. The ring cutting device is arranged in the box, which can effectively reduce the safety hazards brought to the operator's working environment.

[0044] In another embodiment, a fixed box 12 is provided on the right side of the rotating part and the supporting part 40, and a motor is provided on the right side of the supporting part 40. The output end of the motor passes through the side wall of the supporting part 40 to the fixed box 12, and the two rollers 11 pass through the side wall of the fixed frame 10 to the fixed box 12. The two rollers 11 are driven by the motor to roll in the same direction through a synchronous pulley.

The elastic force of the tension spring 26 on the movable rod 24 can effectively increase the fixing force of the hob 25 on the wood, thereby improving the flexibility and practicality of the hob 25, and can effectively handle irregular protrusions on the wood to avoid jamming. The minimum distance between the two hobs 25 is greater than the width of the push rod 31 to avoid the hob 25 touching the push rod 31 and causing damage to the equipment.

[0048] In another embodiment, the support box 20 is equipped with an infrared height gauge on the wood feed side. The infrared height gauge can effectively measure the wood diameter and work in conjunction with the PLC controller to mobilize the electric telescopic rod 21 to extend and retract, thereby completing the ring cutting of the wood and improving the automation level of the equipment.

It can also reduce the generation of wood dust and reduce pollution to the working environment.

[0051] In another embodiment, fixed baffles 14 are movably connected to the fixed frame 10 on both sides along the moving direction of the pushing device. The bottom side of the fixed baffle 14 is connected to the inner side of the fixed frame 10 through a pressure spring. The fixed baffle 14 is connected to the fixed frame 10 through a spring. An external wood transporter can be connected. By pressing the fixed baffle, the wood can be transported to the roller 11, which facilitates the transportation of the wood.

[0052] In another embodiment, an opening is provided below the circular cutting portion, and a wood chip collection box 41 is provided at the lower end of the opening.

The wood moves to the mouth of the support box 20, and the infrared height measuring instrument monitors the height of the wood. After judgment by the PLC controller, the signal is transmitted to the electric telescopic rod 21 to control the electric telescopic rod 21 to extend and retract up and down. The rotating wood is limited and squeezed by the joint operation of the movable rod 24, the hob 25 and the tension spring 26. When the hob 25 cuts the wood, the hob 25 rotates in the opposite direction to the wood, and the watering port 29 sprinkles water on the wood. The generated wood chips flow into the wood chip collection box 41 in the support part 40 through the water flow.
