Description

Technical Field

[0001] The present invention relates to the technical field of a material pusher for high-strength bolt production equipment, and particularly to a flap device for a material pusher used in high-strength bolt production. Background Art

[0002] High-strength bolts refer to bolts made of high-strength steel or those that require a relatively large pre-tightening force. They are mostly used for the connection of bridges, rails, high-pressure and ultra-high-pressure equipment to ensure the stability and safety of the structure. Their core characteristic lies in applying the pre-tightening force, rather than simply relying on the high strength of the material.

[0003] A material pusher, also known as a feeding device, is used to evenly or quantitatively supply materials from a storage bin or other storage equipment to a receiving equipment. It is an essential equipment for realizing automated flow production. The main function of the material pusher used in bolt production is to provide raw materials for bolt production, and through the transmission movement between machines, the materials are agitated so that the materials can move evenly and appropriately to the bolt production device.

[0004] The existence of the flap device is to assist the pusher in controlling the amount of materials. In the existing high-strength bolt production line, in the process of discharging materials, the materials fall freely, which is likely to impact the flap and easily cause damage. Moreover, during the flap process, the material flow rate cannot be effectively controlled, resulting in material accumulation or interruption due to flow rate fluctuations, which affects the bolt production efficiency. Summary of the Invention

[0005] The purpose of the present invention is to provide a flap device for a material pusher used in high-strength bolt production to solve the problems raised in the above background art.

The feeding cylinder adopts a structure of an upper hopper type and a lower cylindrical type, and the upper hopper structure and the lower cylindrical structure are integrally formed. Three support legs are installed at the bottom of the feeding cylinder and are evenly distributed to ensure the stable operation of the equipment. A control panel is arranged on the front of the feeding cylinder, integrating sensors and a microprocessor to monitor the material level and operating status in real time.

Both sides of the guiding resistance blocks are designed with rounded corners to facilitate the smooth sliding of materials. The guiding resistance blocks are made of high-strength wear-resistant alloy, which can effectively guide the material flow direction and avoid accumulation.

[0008] Preferably, a driving shaft is arranged inside the circular flap trough body. Both ends of the driving shaft respectively pass through the side wall of the circular flap trough body through bearings and extend to the outside of the material pushing cylinder, and are rotationally connected to the material pushing cylinder. One end of the driving shaft is connected to the output shaft of the flap driving motor. The flap driving motor is installed on the back of the material pushing cylinder.

Both sides of the flap blades are provided with micro-concave structures to enhance the material grasping force and ensure smooth and efficient flap actions; the flap blades are made of PMAFC / PU composite buffer material, which has excellent wear resistance and impact resistance and significantly extends the service life. The edges of the flap blades are designed with a multi-faceted composite edge structure, with a unique shape of four corners and three sides, which plays a role in stress dispersion: the multi-edge design reduces single-point stress concentration and improves the overall structural strength; hydrodynamic optimization: in the fluid contact scenario, the three-sided structure can guide the airflow and reduce resistance. The contact surface between the flap blades and the blanking flap chamber adopts an arc transition to ensure smooth transition of materials during the flipping process.

[0010] Preferably, a pressure sensor is arranged at the end side of each flap blade. The pressure sensor is signal-connected to the control panel to detect the force-bearing situation of the flap blades in real time and feedback it to the control panel, so as to ensure that the system compares the preset average load value with the actual load value and automatically drives the flap driving motor to adjust the rotation speed, thereby adjusting the flap rotation speed.

[0011] Preferably, the flap mechanism specifically includes a flap. The flap is connected to the hinge seat through a hinge. The hinge seat is installed on the side wall of the blanking channel outlet. The flap is made of lightweight high-strength alloy material.

[0013] Preferably, a flow sensor is provided at the top of the inner cavity of the discharge channel, and the flow sensor is connected to the control panel signal to monitor the material flow in real time. The data is fed back to the control system to ensure that the system compares the preset flow value with the actual flow value, automatically adjusts the telescopic range of the telescopic cylinder, and then adjusts the opening and closing angle of the flap to accurately control the falling speed of the material.

[0014] The present invention provides a plate turning device for a material feeding machine for producing high-strength bolts. The device has the following beneficial effects: (1) During the flipping process, the present invention provides a pressure sensor on the flap blade. The sensor detects the load-bearing condition of the flap blade in real time and feeds back to the control panel, thereby ensuring that the system compares the actual load value with the preset average load value, automatically drives the flap drive motor to adjust the speed, thereby driving the flap blade to adjust the speed, achieving precise load balance and avoiding overload damage; at the same time, the synergistic effect of the micro-motion sensor and the flow sensor ensures that the opening and closing angle of the flap is accurately matched with the material flow, optimizes the material unloading process, reduces energy consumption, and improves production efficiency.

[0015] (2) The present invention designs the edge of the flap blade to be a multi-faceted composite edge structure with a unique shape of four corners and three sides.

[0016] (3) The present invention allows materials to be thrown into the material discharge channel under the action of centrifugal force, and monitors the material flow in real time through a flow sensor. The data is fed back to the control system to ensure that the system compares the preset flow value with the actual flow value, and automatically adjusts the extension and contraction range of the telescopic cylinder. Through the extension and contraction action of the telescopic cylinder, the short limit rod is driven to move with the movable seat as the fulcrum, thereby driving the long connecting rod and the long limit rod to move in linkage, wherein the long limit rod moves with another movable seat as the fulcrum, thereby driving the short connecting rod to move, and finally achieving the adjustment of the opening and closing angle of the flap, effectively controlling the material flow, thereby avoiding material accumulation or flow interruption caused by flow fluctuations.
