Description

Technical Field

[0001] This utility model belongs to the field of unloading gate technology and relates to an induction unloading gate mechanism. Background Technology

[0002] The main drawbacks of existing inductive unloading gates include insufficient sensor sensitivity, frequent malfunctions, delayed response time, and high maintenance costs. These drawbacks are typically related to limitations in sensor technology and design flaws. Sensors may fail to accurately distinguish between material and non-material signals, leading to malfunctions; or sensors may be sensitive to environmental changes (such as temperature and humidity), affecting their stability; wear and tear on mechanical components can also degrade the performance of the inductive unloading gate.

[0003] Conventional solutions include adjusting sensor sensitivity settings, adding shielding measures to reduce environmental interference, and regular maintenance and replacement of vulnerable parts. However, these methods also have drawbacks. Adjusting sensitivity may not completely solve the problem, as environmental changes and material characteristics may require continuous adjustments, increasing operational complexity; shielding measures may affect other functions of the unloading gate, reducing overall efficiency; and regular maintenance and replacement of parts increase operating costs and downtime, affecting production continuity. Therefore, there is an urgent need for a sensor-based unloading gate mechanism to address these issues. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide an induction unloading gate mechanism to solve the problems mentioned in the background art.

[0006] The guide frame has a rectangular cross-section when viewed from above. Inside the guide frame, there is a set of guide cavities for guiding external materials. At the lower end of the guide cavity, there are two sets of lower cavity doors, and the two sets of lower cavity doors move downwards and open and close in a left-right position.

[0007] The right side of the guide frame is equipped with an infrared sensor for detecting the material accumulation height. The right side of the guide frame is also equipped with an inner push rod for controlling the rotation angle of the movable arm. This inner push rod is an electric push rod. The infrared sensor and the inner push rod are connected via a controller. To the right of the inner push rod is a movable arm for applying force to open and close the lower cavity door. The infrared sensor detects the material accumulation height inside the guide cavity. When the material accumulates to a certain height inside the guide cavity, the controller controls the inner push rod to rotate the movable arm and side rotating rod, thereby driving the two sets of pull arms to rotate around the axis. The pull arms then drive the movable head to move up and down along the guide rod. Simultaneously, the movable head controls the two sets of side support rods to open the two lower cavity doors and perform unloading operations.

[0008] In a preferred embodiment, the lower end of the movable arm is provided with a set of side rotating rods for transmitting the rotational force of the movable arm, and the left ends of the front and rear sides of the side rotating rods are respectively provided with a set of pull arms for applying force to the movable head.

The guide rods are movably engaged with the mounting hole, and a set of connectors is provided on the left and right sides of the lower end of the movable head.

[0012] In a preferred embodiment, each set of connectors is movably connected to the upper end of a set of side support rods via a set of rotating shafts, and the lower end of each side support rod is provided with a set of lower connecting supports, which are movably connected to the side support rods via rotating shafts.

[0013] In a preferred embodiment, the lower connecting support is fixedly connected to the lower cavity door, and each set of the lower cavity door is movably connected to a set of guide frames through a hinge. The two sets of lower cavity doors rotate synchronously in mirror image, and the material unloading rate can be adjusted by controlling the adjustment stroke of the two sets of lower cavity doors, thereby facilitating flexible use under different unloading rate requirements.

[0014] The upper end of the pull arm is provided with a set of tension springs for storing its kinetic energy. The outer side of the tension spring is provided with a set of limiting cylinders for maintaining the position of the tension spring. The limiting cylinders are sleeved with the tension spring, and the upper end of the tension spring is provided with a set of fixing seats for limiting and fixing it.

[0015] After adopting the above technical solution, the beneficial effects of this utility model are as follows: by using an infrared detection sensor to detect the material accumulation height inside the material guiding cavity, and when the material accumulates to a certain height inside the material guiding cavity, the controller controls the inner push rod to control the movable arm and the side rotating rod to rotate, thereby driving the two sets of pull arms to rotate around the shaft core, and causing the pull arms to drive the movable head to move up and down along the guide rod. At the same time, the movable head controls the two sets of side support rods to open the two sets of lower cavity doors and carry out unloading operations. By controlling the adjustment stroke of the two sets of lower cavity doors, the material unloading rate can be adjusted, thus facilitating flexible use under different unloading rate requirements.
