Description

Technical Field

[0001] This utility model relates to the technical field of granular material feeding equipment, specifically a damping mechanism for controlling the discharge of granular materials. Background Technology

[0002] In industries such as pharmaceuticals, food processing, and chemicals, controlling the discharge rate of granular materials is crucial for ensuring production efficiency and product quality. Traditional feeding equipment typically controls the discharge rate by adjusting valve opening. However, existing technologies have significant limitations. For example, feeding equipment with a fixed discharge rate uses preset valve positions and can only output a single, fixed amount of material. When production or experiments require adjustments to the discharge rate, frequent equipment replacement or reconfiguration of the mechanical structure is necessary, leading to cumbersome operation, low efficiency, and high equipment purchase and maintenance costs. Adjustable mechanisms, such as discrete adjustable-gear mechanisms, achieve limited gear adjustment (e.g., multi-gear valve switching) through mechanical slots or gear locking structures. Although such mechanisms can meet the needs of small discharge rate variations, their adjustment accuracy is limited by fixed gear intervals and cannot achieve continuous stepless adjustment (continuous angle adjustment). If adjustment to a non-calibrated discharge rate is required, the valve opening cannot be precisely controlled, resulting in material discharge errors.

[0003] In addition, existing mechanisms also face the problem of insufficient mechanical stability in practical applications. In actual production, large batches and multiple discharges are often required. When existing mechanisms are running, vibration or mechanical forces between components can easily cause valve position deviation, making it impossible to maintain a stable opening after adjustment, which further aggravates discharge deviation.

[0004] Therefore, there is an urgent need for a damping mechanism that can achieve stepless adjustment and stable state after adjustment, so as to improve the accuracy and adaptability of the valve opening adjustment control at the material outlet. Utility Model Content

[0005] The purpose of this invention is to provide a damping mechanism for controlling the discharge of granular materials, so as to solve the problems mentioned in the background art and achieve stepless adjustment and stable state after adjustment.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A damping mechanism for controlling the discharge of granular materials includes a base with uniformly distributed scale markings along its circumference. A magnetic component is fixed to the base by fasteners. A rotating handle assembly is rotatably connected to the base and is magnetically connected to the magnetic component. A damping layer is covered on the rotating handle assembly.

[0008] As a further embodiment of this utility model: in order to fix the magnetic component on the base, the base is provided with a mounting groove, the bottom of the mounting groove is provided with a threaded hole for fixing the magnetic component, the magnetic component is provided with a countersunk mounting hole, and the fastener passes through the countersunk mounting hole and the threaded hole in sequence to fix the magnetic component in the mounting groove.

[0009] As a further embodiment of this utility model: In order for the rotating handle assembly to rotate within the base, the rotating handle assembly includes a flange, a handle is vertically connected to the outer end face of the flange, a positioning post is fixedly connected to the inner end face of the flange, the base is provided with a positioning hole and a placement groove, the positioning post is inserted into the positioning hole, and the flange is installed in the placement groove.

[0010] As a further aspect of this utility model: in order to increase the adjustment accuracy when rotating the rotary handle assembly, the damping layer covers the contact surface of the flange that contacts the placement groove, and is used to provide rotational damping force.

[0011] As a further aspect of this utility model: In order to facilitate observation of the angular change of the rotating handle assembly, the flange edge is provided with an indicator mark that cooperates with the scale mark to display the rotation angle of the rotating handle assembly.

[0012] As a further embodiment of this invention, the outer wall of the substrate has grooves for weight reduction.

[0013] As a further embodiment of this utility model: in order to adjust the valve opening and closing size and thus control the material dropping rate, the positioning post extends to have two connecting posts for inserting into the valve that controls the material dropping.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] This invention features a novel structure. A magnetic component is fixed within the substrate, and this component magnetically attracts the flange on the rotary handle assembly, preventing the handle assembly from detaching during rotation. Simultaneously, a damping layer covering the flange provides rotational damping force, increasing the adjustment accuracy of the rotary handle assembly and ensuring stable positioning after adjustment, thus achieving stepless precise adjustment of the rotation angle. The scale markings on the substrate and the indicator markings on the flange work together to facilitate observation of the rotation angle of the rotary handle assembly, further enhancing adjustment accuracy.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

For ease of description, the dimensions of the various parts shown in the accompanying drawings are not drawn to actual scale.

They are only for the convenience of describing this application and simplifying the description. Unless otherwise stated, these directional terms do not indicate or imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on the scope of protection of this application. The directional terms "inner" and "outer" refer to the inner and outer contours relative to the outline of each component itself.

[0026] Please see Figure 1-6 In this embodiment of the present invention, a damping mechanism for controlling the discharge of granular materials includes a base 1. One end edge of the base 1 is engraved with uniformly distributed scale markings 13 along its circumferential direction to indicate the rotation angle of the rotating handle assembly. A groove is formed on the outer wall of the base 1 to reduce the overall weight of the mechanism.

[0027] The base 1 has four symmetrical mounting slots 11 on one end face. Threaded holes 12 are provided at the bottom of each mounting slot. Magnetic components 2 are embedded within the mounting slots 11. A countersunk mounting hole 21 is provided at the center of each magnetic component 2. Fasteners 3 pass through the countersunk mounting hole 21 and the threaded hole 12 in sequence, securing the magnetic component 2 to the base 1 for magnetically adsorbing the flange 41 of the rotary handle assembly 4. In this embodiment, the fasteners 3 are countersunk bolts. The base 1 has a placement slot 15 at one end for mounting the flange 41 on the rotary handle assembly 4. The four mounting slots 11 are surrounded by the placement slot 15. A positioning hole 14 is provided at the center of the placement slot 15. A positioning pin 43 on the rotary handle assembly 4 is rotatably connected to the positioning hole 14. The positioning pin 43 is welded to the inner end face of the flange 41. A handle 44 is vertically welded to the outer end face of the flange 41 for rotating the rotary handle assembly 4.

[0028] The positioning column 43 extends away from the flange 41 with two connecting columns 431. The ends of the connecting columns 431 are inserted into the valve (such as a butterfly valve) that controls the material discharge from the outlet and are fixedly connected to the valve plate. When the rotating handle assembly 4 is rotated by the handle 44, the flange 41 drives the positioning column 43 to rotate, which in turn drives the connecting columns 431 to rotate synchronously and drives the valve plate to rotate. The rotation of the handle 44 directly drives the valve plate to rotate around the axis, changing the cross-sectional area of ​​the material channel, thereby adjusting the opening and closing of the valve and controlling the material discharge. An indicator mark 45 that matches the scale mark 13 is engraved on the outer end face edge of the flange 41, making the rotation angle of the rotating handle assembly 4 easier to observe.

[0029] When flange 41 is inserted into placement groove 15, magnetic component 2, which is fastened in mounting groove 11, magnetically attracts flange 41 to attract rotating handle assembly 4, preventing rotating handle assembly 4 from falling off base 1, so that rotating handle assembly 4 can be continuously adjusted in angle without fixed position on base 1.

[0030] The flange 41 has a damping layer 42 on the contact surface that contacts the placement groove 15. This layer provides rotational damping force when the rotary handle assembly 4 is rotated, thereby improving the rotational adjustment accuracy. At the same time, it prevents the adjustment position from being affected by the displacement of the mechanism due to vibration or external force after the rotary handle assembly 4 is adjusted.

[0031] This utility model has a novel structure and stable operation. In use, the magnetic components 2 are first embedded into the mounting grooves 11. Then, fasteners 3 are used to pass through the countersunk mounting holes 21 on the magnetic components 2 and threadedly connected to the threaded holes 12, securing the magnetic components 2 in the mounting grooves 11. Next, the positioning pin 43 of the rotating handle assembly 4 is inserted into the positioning hole 14, and the connecting pin 431 is inserted into the valve controlling the material discharge. The flange 41 is then embedded in the placement groove 15, ensuring that the flange 41 is magnetically attracted to the magnetic components 2. This ensures that the rotating handle assembly 4 does not detach from the base 1 while rotating and connecting to it. By rotating the handle 44, the indicator mark 45 on the edge of the flange 41 is aligned with the scale mark 13, and then rotation begins. Adjusting the handle 44, the friction between the placement groove 15 and the damping layer 42 makes the rotation adjustment more precise. The handle 44 drives the rotating handle assembly 4 to rotate as a whole, causing the connecting column 431 to move the valve that controls the material discharge, changing the valve opening and controlling the discharge amount. At this time, observe the angle difference between the indicator mark 45 and the scale mark 13. Adjust the rotation angle of the rotating handle assembly 4 repeatedly according to the actual required discharge amount. When the discharge amount is appropriate, stop rotating the adjusting handle 44. At this time, the friction between the placement groove 15 and the damping layer 42 can reduce the relative displacement between the rotating handle assembly 4 and the base 1. The magnetic attraction between the magnetic component 2 and the flange 41 stabilizes the position after adjustment, thereby stabilizing the change in discharge amount within an acceptable range.

Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
