[0002] Vibrating feeder, also known as vibration feeder, is a kind of equipment which can feed block, granular, powder or a mixture of these three forms to the receiving device evenly, quantitatively and continuously. With the vertical mill being widely used in many industries, the vertical mill system operates under negative pressure and high temperature, so the corresponding feeding mechanism is required to have a closed air lock device; and the vertical mill feeds a large amount of material, the size and material are uneven, and it is mixed with powdery materials, and in some areas, the material has the characteristics of high humidity and high viscosity.

[0003] With reference to the existing patent publication number: CN219708506U, a built-in air lock plate valve of a vibrating feeder comprises: a feeder and an air lock plate valve mechanism installed inside the discharge end of the feeder, the air lock plate valve mechanism comprises a valve plate, both sides of the top of the valve plate are provided with automatically rotatable rotating mechanisms, the two rotating mechanisms are both installed on the feeder, and the two rotating mechanisms are added to the discharge end, so that the valve plate can be automatically flipped in the discharge end through the rotating mechanism, and the built-in air lock valve plate valve, according to the negative pressure value of the mill and the size of the machine model, adjusts and calculates the optimal valve plate weight by cutting the contour of the support plate, so that the valve plate can automatically adjust the valve plate angle in real time as the material layer changes, perfectly adapting to the working conditions of the mill.

[0004] However, in actual use of the existing vibrating feeder, the flow of external environmental airflow can easily drive the feed inside the feeder to flow together, which not only affects the quality of the feed but may also cause the feed to be scattered and wasted, affecting the normal supply of the feeder. The airflow can easily flow inside the feeder, and the protection effect on the feeder is poor. Utility Model Content

[0005] The purpose of the utility model is to solve the shortcomings of the prior art and propose a wind lock structure for a vibrating feeder. The utility model can guide the airflow flowing through the feeder through the guide part, so that the airflow passes through a certain path and prevents the feeding material from scattering. At the same time, the transmission mechanism can drive the wind lock baffle to move to seal the discharge end of the feeder, so that the material in the feeder can be evenly supplied and the impact is reduced.

[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0007] A wind locking structure for a vibrating feeder, comprising:

[0008] The upper part of the machine body is open and has a feeding space inside;

[0009] A bracket, which is arranged horizontally with the machine body and installed at the end of the machine body in the feeding direction;

[0015] The utility model is further configured such that the curvature of the protrusion is greater than 180° and the horizontal height is higher than the horizontal height of the wind-locking baffle.

[0016] The utility model is further configured such that the guide parts are arranged alternately and are located below the transmission mechanism for guiding the flow of air.

[0017] The utility model is further configured that an extension portion located above the convex block is installed on the upper portion of the wind lock baffle, and the extension portion is in contact with the cam.

[0018] The utility model is further configured that an elastic member in contact with the wind-locking baffle is installed at the end of the machine body in the feeding direction.

[0032] Reference Figure 1-4 A wind locking structure of a vibrating feeder comprises: a body 1, the upper part of which is open and has a feeding space inside; a bracket 3, which is arranged horizontally with the body 1 and installed at the end of the feeding direction of the body 1; a rotating member 10, the length of which is greater than the width of the body 1 and is rotatably connected between the brackets 3; a wind locking baffle 2, the horizontal height of which is greater than the horizontal height of the end of the feeding direction of the body 1 and is rotatably installed on the surface of the rotating member 10; the wind locking baffle 2 is provided with a plurality of arc-shaped guide parts 14 on the inner side relative to the body 1, and the guide parts 14 can guide the flow direction of the airflow passing through the body 1 to reduce the impact on the feeder, and a transmission mechanism is installed on the upper part of the body 1, and the action can be transmitted to the position of the wind locking baffle 2 through the transmission mechanism and drive the wind locking baffle 2 to move.

[0033] Reference Figure 2-3 The transmission mechanism includes: a motor 5, a connecting plate 6, a driving shaft 7, a cam 8 and a protrusion 9; the motor 5 is installed on the upper part of the body 1, the connecting plate 6 is installed on the upper side of the body 1 relative to the motor 5, the driving shaft 7 is connected to the output end of the motor 5 and its end away from the motor 5 is connected to the connecting plate 6, the cam 8 is installed on the surface of the driving shaft 7, and the protrusion 9 is arranged in an arc shape and installed on the surface of the cam 8. After the motor 5 is working, it can drive the driving shaft 7 to rotate, and the driving shaft 7 drives the cam 8 and the protrusion 9 to rotate, so that the extension part 4 can be moved under the action of the protrusion 9 and the cam 8.

[0034] Specifically, the arc of the protrusion 9 is greater than 180° and the horizontal height is higher than the horizontal height of the wind lock baffle 2. The protrusion 9 can continue to rotate following the operation of the motor 5, so that the closing time of the wind lock baffle 2 on the machine body 1 is greater than its unfolding time and has a certain regularity and continuity, thereby reducing the impact of airflow flow, and maintaining a uniform supply of raw materials in the machine body 1, thereby improving the use effect.

[0035] In this embodiment, the guide parts 14 are arranged alternately and located below the transmission mechanism to guide the flow of air, which can avoid interference between the guide parts 14 and the operation of the transmission mechanism, and under the action of the guide parts 14, the airflow path can be guided to a certain extent, so that the material carried by the airflow can be blocked by the guide parts 14 and the extension parts 4 and fall downward into the body 1, reducing the waste of resources.

[0036] Reference Figure 1-3 The upper part of the wind lock baffle 2 is installed with an extension part 4 located above the protrusion 9. Through this implementation, the extension part 4 can guide the airflow flowing through the body 1 to a certain extent, and block the materials mixed in the airflow to improve the utilization rate. At the same time, the extension part 4 is in contact with the cam 8, so that the cam 8 can drive the protrusion 9 to lift the extension part 4 during the rotation process, thereby performing synchronous activities and improving the linkage.

[0037] Reference Figure 3 An elastic member 13 in contact with the wind lock baffle 2 is installed at the end of the feeding direction of the machine body 1. Through this implementation, when the wind lock baffle 2 is flipped by the rotating member 10, the elastic member 13 will be compressed first, and then after the protrusion 9 is away from the extension part 4, the wind lock baffle 2 can be pushed to reset under the action of the elastic member 13, so that the wind lock baffle 2 can be in a vertical position, thereby expanding the discharge position of the machine body 1, which is beneficial to its movement.

[0038] Reference Figure 2-3 A counterweight 11 for adjusting the weight of the wind lock baffle 2 is installed on the outer side of the wind lock baffle 2 relative to the machine body 1. Through the action of the counterweight 11, the lower weight of the wind lock baffle 2 can be increased, so that the wind lock baffle 2 can be restored to a vertical state under the action of the rotating part 10, which is convenient for the feeder to supply and avoid interference. A screening part 12 is installed on the inner side of the wind lock baffle 2 relative to the machine body 1 and is located below the machine body 1. It can screen and filter the supplied material and impurities in the airflow to improve the quality of the material supplied by the feeder.

[0039] Working principle: When using the utility model, first, the motor 5 can be started, and the motor 5 can drive the driving shaft 7 to rotate, and the driving shaft 7 can drive the cam 8 and the protrusion 9 to rotate, so that the extension part 4 can be moved under the action of the protrusion 9 and the cam 8, so as to drive the wind lock baffle 2 to flip under the action of the rotating member 10, so as to close the end of the machine body 1 to a certain extent, reduce the influence of air flow, and because the arc of the protrusion 9 is greater than 180°, the closing time of the wind lock baffle 2 to the machine body 1 is greater than the time of its expansion and has a certain regularity, so as to maintain the original air flow in the machine body 1. In order to ensure uniform supply of materials and improve the use effect, a wind locking baffle 2 is arranged at the end of the travel direction of the feeder. Under the action of the wind locking baffle 2, the airflow flowing through the body can be blocked to a certain extent, and under the action of the guide part 14 and the extension part 4, the airflow path can be guided to a certain extent, so that the material carried by the airflow can be blocked under the action of the guide part 14 and the extension part 4 and fall downward into the body 1, reducing the waste of resources. At this time, the screening component 12 installed at the lower part of the wind locking baffle 2 can screen and filter the supplied material and impurities in the airflow to a certain extent, thereby improving the quality of the material supplied by the feeder.
