[0022] The embodiments of this application will be described in more detail below with reference to the drawings. Although the embodiments of this application are shown in the drawings, it should be understood that this application can be implemented in various forms and should not be limited by the embodiments set forth herein. On the contrary, these embodiments are provided to make this application more thorough and complete, and to fully convey the scope of this application to those skilled in the art.

[0023] Please refer to Figure 1 , Figure 2 and Figure 3, this application provides a posture screening device for small-diameter bamboo cores used in composite wood-based panels, including a feeding hopper 1, screening bars 2, a first connecting rod 3, and a second connecting rod 4; the bottom of the feeding hopper 1 is square, and for the convenience of bamboo gathering, the upper part of the feeding hopper 1 can be set in a funnel shape.

[0024] Chute grooves are respectively arranged on the four side surfaces of the bottom of the feeding hopper 1. As shown in the figure, the length of the chute groove is greater than the length of the feeding hopper 1. The screening bars 2 are inserted into the chute grooves, and thus the screening bars 2 are slidably installed at the bottom of the feeding hopper 1, enabling adjacent screening bars 2 to approach or move away from each other.

[0025] The screening bars 2 are arranged in two layers, and there is a slight gap between the upper and lower layers of screening bars 2 so that the screening bars 2 located in the upper and lower layers respectively do not interfere with each other.

[0026] The screening bars 2 in the same layer are evenly spaced, and the ends of adjacent screening bars 2 are connected by a first connecting rod 3 and a second connecting rod 4 that are cross-hinged. Among them, one screening bar 2 is hinged to one end of the first connecting rod 3 and slidably connected to one end of the second connecting rod 4. The adjacent screening bar 2 is hinged to the free end of the second connecting rod 4 and slidably connected to the free end of the first connecting rod 3, and the hinged ends of the first connecting rod 3 and the second connecting rod 4 are arranged on the same side; so that when adjusting the distance between adjacent screening bars 2, only the distance between two of the screening bars 2 needs to be adjusted, and the remaining adjacent screening bars 2 are synchronously adjusted under the action of the cross-hinged first connecting rod 3 and second connecting rod 4, and the adjustment amplitudes are the same.

[0027] The upper and lower layers of screening bars 2 are arranged in an interlaced manner to form square blanking holes. A vibration motor 5 is installed on the outer side wall of the feeding hopper 1 to drive the feeding hopper 1 to vibrate vertically.

[0028] During the use process of this application, the feeding hopper 1 is suspended above the ground, and the height between the bottom of the feeding hopper 1 and the ground is slightly less than the length of the bamboo section; the bamboo sections are put into the feeding hopper 1 by manual or mechanical handling; the vibration motor 5 is connected to an external power supply, and the vibration motor 5 is powered on to work, driving the feeding hopper 1 to vibrate vertically, so that the bamboo sections continuously fall vertically from the blanking holes until they are vertically placed on the ground. Subsequently, the feeding hopper 1 is lifted, and neatly vertically placed bamboo sections can be obtained.

[0029] The adjustment of the bamboo posture is realized by means of mechanical vibration, greatly improving the working efficiency of bamboo placement and reducing the labor intensity of the staff.

[0030] In this embodiment, an inverted L-shaped bracket can be set, a cylinder is arranged at the horizontal end of the bracket, and the lower end of the cylinder is fixedly connected to the feeding hopper 1, so as to drive the feeding hopper 1 to move up and down through the cylinder.

[0031] In some specific embodiments, among the screening bars 2 on the same layer, the screening bar 2 located at the middle position is fixedly connected to the feed hopper 1. The hinge shaft of one of the first connecting rods 3 and the second connecting rod 4 is hinged to one end of the electric telescopic rod 6, and the other end of the electric telescopic rod 6 is hinged to the feed hopper 1. When the electric telescopic rod 6 extends, it drives the corresponding screening bar 2 away from the screening bar 2 located at the middle position, so that the distance between adjacent screening bars 2 becomes larger. On the contrary, when the electric telescopic rod 6 shortens, it drives the corresponding screening bar 2 closer to the screening bar 2 located at the middle position, so that the distance between adjacent screening bars 2 becomes smaller. Thus, the purpose of adjusting the distance between adjacent screening bars 2 through the electric telescopic rod 6 is achieved. Compared with manual adjustment, the adjustment range is more accurate. At the same time, the electric telescopic rod 6 can play a limiting role to effectively prevent the change of the position of the screening bar 2 when the feed hopper 1 vibrates.

[0032] In some specific embodiments, a distance measuring sensor 7 is provided on one of the screening bars 2, and a reflective sheet 8 for cooperating with the distance measuring sensor 7 is provided on the adjacent screening bar 2. The distance measuring sensor 7 is connected to the signal input end of the controller; the electric telescopic rod 6 is electrically connected to the signal output end of the controller. When it is necessary to adjust the distance between adjacent screening bars 2, the distance measuring sensor 7 detects the distance between two adjacent screening bars 2 in real time and transmits it to the controller. Then the controller controls the electric telescopic rod 6 to extend or shorten to the corresponding amount, so as to realize the automatic adjustment of the distance between adjacent screening bars 2 and ensure the accuracy of the adjustment.

[0033] At the same time, this can ensure that the adjustment of the distance between the upper and lower layers of screening bars 2 is consistent, so that the falling holes before and after adjustment are always square.

[0034] In some specific embodiments, it further includes a conveyor belt 9 arranged below the feed hopper 1. The working surface of the conveyor belt 9 is a plane. After the bamboo segments leave the feed hopper 1, they are neatly arranged on the conveyor belt 9 and are conveyed to the next process through the conveyor belt 9.

[0035] The above has described the embodiments of the present application. The above description is exemplary and not exhaustive, and is not limited to the disclosed embodiments. Many modifications and variations are obvious to those of ordinary skill in the art in the technical field without departing from the scope and spirit of the described embodiments. The choice of terms used herein is intended to best explain the principles of the embodiments, practical applications, or improvements to the technologies in the market, or to enable other ordinary technical personnel in the technical field to understand the embodiments disclosed herein.
