Detailed implementation mode

[0019] An automatic centering four - sided wood planing device for wood cores includes a conveying device, a wood planing knife and a workbench. The conveying device and the wood planing knife are respectively arranged on the workbench. The wood planing knife is fixedly arranged on the workbench through a mounting seat. The workbench is provided with a bracket for fixed installation. The conveying device conveys the wood, and the wood planing knife planes the upper, lower, left and right four surfaces of the conveyed wood respectively. The wood planing equipment also includes a central positioning device. The conveying device includes a feed conveyor, an intermediate conveyor and a discharge conveyor. The feed conveyor is connected to the central positioning device. Through the central positioning device, the central positions of woods with different diameters can be positioned at the same height position during feeding. The wood planing knife includes an upper wood planing knife, a lower wood planing knife and a side wood planing knife. From the feed direction to the discharge direction, the lower wood planing knife, the side wood planing knife and the upper wood planing knife are sequentially arranged on the workbench. That is, first plane the lower surface of the wood, then plane the left and right side surfaces of the wood simultaneously, and finally plane the upper surface of the wood, so as to complete the planing of the upper, lower, left and right four surfaces of the wood. Planing the lower surface of the wood first makes the lower surface of the wood in a flat state during the subsequent conveying process, which can better facilitate conveying and positioning.

[0020] The side wood planing knife includes a left wood planing knife and a right wood planing knife. The left wood planing knife and the right wood planing knife are in relative positions respectively. The wood passes through the gap between the left wood planing knife and the right wood planing knife, and can plane the left and right side surfaces of the wood simultaneously. Dust removal interfaces are respectively provided at the upper wood planing knife, the lower wood planing knife and the side wood planing knife. Connecting to a dust collector through the dust removal interfaces can perform dust suction and dust removal.

[0021] The central positioning device includes a rack, a gear, and a fixing frame. The fixing frame is arranged on the workbench. Slide rails are respectively arranged on both sides of the fixing frame. There are two racks, which are respectively arranged on the slide rails on both sides of the fixing frame and can move up and down along the slide rails. The gear is placed between the two racks and meshes with the two racks respectively. Specifically, the racks include a left rack and a right rack, the slide rails include a left slide rail and a right slide rail, the sliders include an upper slider and a lower slider. The left slide rail and the right slide rail are respectively arranged on the fixing frame. The upper slider and the left rack are arranged on the left slide rail, and the upper slider and the left rack are fixedly connected. The lower slider and the right rack are arranged on the right slide rail, and the lower slider and the right rack are fixedly connected. The upper conveyor wheel is fixedly connected to the upper slider, and the lower conveyor wheel is fixedly connected to the lower slider. When large-diameter wood enters between the upper conveyor wheel and the lower conveyor wheel for conveying, the large-diameter wood will push against the upper conveyor wheel and the lower conveyor wheel, causing the upper conveyor wheel and the lower conveyor wheel to open. Since the left rack and the right rack are connected by a gear, the distances that the left rack and the right rack move downward relative to each other are the same. Therefore, the central positions of each piece of wood can be positioned at the same height.

[0022] The conveying device includes conveyor wheels, a rotating shaft, a motor, and a cylinder. The conveyor wheels are connected to the motor through the rotating shaft. The conveyor wheels are arranged on the bracket in a movable manner and are connected to the cylinder. The conveyor wheels include an upper conveyor wheel and a lower conveyor wheel. The upper conveyor wheel is provided with a groove, through which the wood can be prevented from slipping, and better conveying can be carried out. During the conveying process, the wood is located in the groove of the upper conveyor wheel. Specifically, the conveying device includes conveyor wheels, a rotating shaft, a rotating shaft housing, a motor, and a cylinder. The motor and the cylinder are respectively arranged on the bracket. The rotating shaft is arranged in the rotating shaft housing. One end of the rotating shaft is connected to the motor, and the conveyor wheels are arranged at the other end of the rotating shaft. The rotating shaft housing is arranged on the bracket in a movable manner and is connected to the cylinder. One end of the rotating shaft housing close to the conveyor wheels is arranged on the bracket by means of hinge, and the other end of the rotating shaft housing far from the conveyor wheels is arranged on the bracket by means of a universal joint. The feeding conveying, intermediate conveying, and discharging conveying, as each conveying device in the conveying device, have the same structure as the conveying device, including conveyor wheels, a rotating shaft, a rotating shaft housing, a motor, and a cylinder. The conveyor wheels are connected to the motor through the rotating shaft. The conveyor wheels are arranged on the bracket in a movable manner and are connected to the cylinder. When in use, the wood is conveyed between the upper conveyor wheel and the lower conveyor wheel, and the wood is clamped and conveyed by the upper conveyor wheel and the lower conveyor wheel.

[0023] The feeding conveyor includes conveyor wheels, which include upper conveyor wheels and lower conveyor wheels. The upper conveyor wheels and the lower conveyor wheels are respectively connected to the toothed bars on both sides of the fixed frame through sliders. The sliders are respectively arranged on the slide rails on both sides of the fixed frame and can move up and down along the slide rails. The sliders are respectively connected to the toothed bars on the same slide rail, and the connected sliders and toothed bars can move up and down along the slide rails simultaneously. The upper conveyor wheels are located above the lower conveyor wheels to form a conveying space. The upper conveyor wheels and the lower conveyor wheels form a set of conveyor wheel groups, and the feeding conveyor is provided with more than 2 sets of conveyor wheel groups. The rotating shaft shells corresponding to the upper conveyor wheels and the lower conveyor wheels on the feeding conveyor are respectively connected to the toothed bars on both sides of the fixed frame through sliders. The rotating shaft shells corresponding to the upper conveyor wheels and the lower conveyor wheels on the intermediate conveyor and the discharging conveyor are respectively arranged on the brackets in a hinged manner.

[0024] The intermediate conveyor includes conveyor wheels and a conveyor platform. The conveyor wheels include upper conveyor wheels and lower conveyor wheels. The upper conveyor wheels and the lower conveyor wheels are arranged oppositely to form a conveying space.

One conveyor platform is located between the left planing knife and the right planing knife, and one conveyor platform is located below the upper planing knife. The function of the conveyor platform is to contact the lower surface of the wood that has been planed into a flat surface during the process of conveying the wood, so as to better clamp, position and convey. The upper conveyor wheels and the lower conveyor wheels are respectively driven by cylinders to clamp the wood.
