[0004] The above-mentioned utility model has the following problems:

[0005] 1. The extruded and defibrated wood chips have a certain viscosity and are easily adhered to the surface of the conveyor belt. And the existing wood chip feeding mechanism has a simple structure and cannot solve the problem of wood chip adhesion, resulting in low conveying efficiency of the extruded and defibrated wood chips. In the long run, it causes the weight of the conveyor belt to increase, increasing the friction between the conveyor belt and the conveyor rollers and affecting the conveying efficiency.

[0006] 2. The existing wood chip feeding mechanism has a simple structure, lacks a shock absorption structure, the operation of the mechanism is often accompanied by vibration, lacks shock protection, and has a short service life.

[0007] Therefore, those skilled in the art provide a novel automatic wood chip feeding mechanism for APMP wood chips to solve the problems raised in the above background technique. Content of the Utility Model

[0008] The purpose of the utility model is to provide a novel automatic wood chip feeding mechanism for APMP wood chips to solve the problems raised in the above background technique.

[0009] To achieve the above purpose, the utility model provides the following technical solutions:

[0010] A novel automatic feeding mechanism for APMP wood chips, comprising a base and a frame. Two groups of rotating shafts are rotatably connected to the inner side wall of the frame. One end of each rotating shaft is fixedly connected with a conveying roller. A conveyor belt is arranged between the conveying rollers. Uniformly arranged baffles are fixedly connected to the surface of the conveyor belt. A housing is fixedly connected to the side wall of the frame. One end of the rotating shaft extends into the housing, and an intermittent wheel is fixedly connected to this end of the rotating shaft. Uniformly arranged dial grooves are formed on the surface of the intermittent wheel. A transmission mechanism for rotating the intermittent wheel is arranged on the side wall of the frame.

[0011] As a further scheme of the utility model: The transmission mechanism includes a driven rod, a semi-circular turntable, a first connecting rod, a dial rod servo motor, a transmission rod, a transmission wheel, a driven wheel and a timing belt.

A first connecting rod is fixedly connected to the side wall of the semi-circular turntable. A dial rod is fixedly connected to the surface of the first connecting rod, and when the dial rod rotates, it fits with the dial groove.

[0012] As a further scheme of the utility model: One end of the driven rod extends out of the housing, and a driven wheel is fixedly connected to this end of the driven rod.

[0013] As a further scheme of the utility model: A servo motor is fixedly connected to the side wall of the frame. The power output end of the servo motor is fixedly connected with a transmission rod. One end of the transmission rod is fixedly connected with a transmission wheel. A timing belt is arranged between the transmission wheel and the driven wheel.

[0014] As a further scheme of the utility model: A controller is fixedly connected to the side wall of the frame. The servo motor is electrically connected to an external power supply through the controller.

[0015] As a further scheme of the utility model: Damping springs are fixedly connected to the inner side wall of the base. The top ends of the damping springs are fixedly connected with a support plate. The top end of the support plate is fixedly connected to the bottom of the frame.

[0016] As a further scheme of the utility model: A groove plate is fixedly connected to the lower surface of the support plate. Embedding grooves are formed on the side wall of the groove plate. A reset block is slidably connected to the inner side wall of the embedding groove.

[0018] Compared with the prior art, the beneficial effects of the utility model are:

[0019] 1. The operation of the servo motor can be controlled by a controller. The rotation of the power output end of the servo motor drives the transmission rod to rotate. The rotation of the transmission rod drives the transmission wheel to rotate. The rotation of the transmission wheel drives the driven wheel to rotate under the action of the timing belt. The rotation of the driven wheel drives the driven rod to rotate. The rotation of the driven rod drives the semi-circular turntable to rotate.

The rotation of the dial rod intermittently drives the intermittent wheel to rotate under the action of the dial groove. The rotation of the intermittent wheel drives the rotating shaft to rotate, that is, the intermittent rotation of the conveying roller is realized. Through the intermittent rotation of the conveying roller, the intermittent movement of the conveyor belt is realized, that is, the conveyor belt stops after moving a certain distance. When the conveyor belt stops, the wood chips on the conveyor belt continue to move under the action of inertia, so that the wood chips are separated from the conveyor belt, which can effectively reduce the adhesion of the wood chips and ensure the conveying efficiency of the feeding mechanism.

[0020] 2. The support of the receiving plate is realized through the combination of the damping spring, the groove plate, the reset block, the reset spring and the second connecting rod, which plays a role in shock absorption and buffering for the overall structure. The vibration accompanied by the operation of the mechanism is transmitted to the damping spring, causing the internal spring of the damping spring to undergo elastic deformation, absorbing part of the energy and generating a reaction force. At the same time, the internal damper consumes energy through friction and fluid resistance, reducing the energy of the vibration system. Combining elastic deformation and energy dissipation, the damping spring can effectively reduce the vibration amplitude of the structure and reduce the impact on the overall structure. Under the action of the damping spring, the damage caused by vibration can be effectively reduced, providing anti-seismic protection and ensuring the stability of the overall structure and the service life.

[0027] Embodiment 1

[0028] Refer to Figures 1-3, this embodiment provides a new type of automatic feeding mechanism for APMP wood chips, including a base 18 and a frame 1. Two groups of rotating shafts 3 are rotatably connected to the inner side wall of the frame 1. One end of the rotating shaft 3 is fixedly connected to a conveying roller 4. A conveyor belt 5 is arranged between the conveying rollers 4. A uniformly arranged baffle 6 is fixedly connected to the surface of the conveyor belt 5.

One end of the rotating shaft 3 extends into the housing 7, and an intermittent wheel 8 is fixedly connected to this end of the rotating shaft 3. Uniformly arranged dial grooves are formed on the surface of the intermittent wheel 8. A transmission mechanism for rotating the intermittent wheel 8 is arranged on the side wall of the frame 1. The transmission mechanism includes a driven rod 9, a semi-circular turntable 10, a first connecting rod 11, a dial rod 12, a servo motor 13, a transmission rod 14, a transmission wheel 15, a driven wheel 16, and a timing belt 17. The bottom wall of the inner cavity of the housing 7 is rotatably connected to a driven rod 9. One end of the driven rod 9 is fixedly connected to a semi-circular turntable 10. A first connecting rod 11 is fixedly connected to the side wall of the semi-circular turntable 10. A dial rod 12 is fixedly connected to the surface of the first connecting rod 11, and when the dial rod 12 rotates, it fits with the dial groove. One end of the driven rod 9 extends outside the housing 7, and a driven wheel 16 is fixedly connected to this end of the driven rod 9. A servo motor 13 is fixedly connected to the side wall of the frame 1. The power output end of the servo motor 13 is fixedly connected to a transmission rod 14. One end of the transmission rod 14 is fixedly connected to a transmission wheel 15. A timing belt 17 is arranged between the transmission wheel 15 and the driven wheel 16. A controller 2 is fixedly connected to the side wall of the frame 1. The servo motor 13 is electrically connected to an external power supply through the controller 2; the operation of the servo motor 13 can be controlled through the controller 2. The rotation of the power output end of the servo motor 13 drives the transmission rod 14 to rotate. The rotation of the transmission rod 14 drives the transmission wheel 15 to rotate. The rotation of the transmission wheel 15 drives the driven wheel 16 to rotate under the action of the timing belt 17. The rotation of the driven wheel 16 drives the driven rod 9 to rotate. The rotation of the driven rod 9 drives the semi-circular turntable 10 to rotate. The rotation of the semi-circular turntable 10 drives the first connecting rod 11 to rotate. The rotation of the first connecting rod 11 drives the dial rod 12 to rotate. The rotation of the dial rod 12 intermittently drives the intermittent wheel 8 to rotate under the action of the dial groove.

The support of the receiving plate is realized through the combination of the damping spring 19, the groove plate 21, the reset block 22, the reset spring 23 and the second connecting rod 24, which plays a role in shock absorption and buffering for the overall structure. The vibration accompanied by the operation of the mechanism is transmitted to the damping spring 19, causing the internal spring of the damping spring 19 to undergo elastic deformation, absorbing part of the energy and generating a reaction force. At the same time, the internal damper consumes energy through friction and fluid resistance, reducing the energy of the vibration system. Combining elastic deformation and energy dissipation, the damping spring 19 can effectively reduce the vibration amplitude of the structure and reduce the impact on the overall structure. Under the action of the damping spring 19, the damage caused by vibration can be effectively reduced, providing anti-seismic protection and ensuring the stability of the overall structure and the service life.
