Detailed Implementation

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0024] This utility model provides, for example Figure 1-4 An automatic unloading metering valve is shown, comprising:

[0025] Casing 1;

[0026] Valve core 11, which is located at the bottom of housing 1;

[0027] Rotating bracket 8 is fixedly connected to one side of housing 1;

[0028] Connector 10 is fixedly connected to one side of valve core 11, and a rotating part is provided at the connection between rotating bracket 8 and connector 10;

[0029] The counterweight frame 3 is fixedly connected to one side of the connector 10. A pressing element is provided on one side of the counterweight frame 3. The horizontal longitudinal section of the rotating bracket 8 is F-shaped.

[0030] It should be noted that the valve core 11 is located at the bottom of the housing 1 to prevent material from falling. An F-shaped rotating bracket 8 is designed to increase the number of connection points between the rotating bracket 8 and the housing 1, thereby strengthening the connection between them. The connecting piece 10 is connected to the rotating bracket 8 via a rotating component, allowing the connecting piece 10 to rotate at the bottom of the rotating bracket 8. During use, as the material increases at the valve core 11 end, when the torque at the valve core 11 end exceeds the torque at the pressing end, the valve core 11 end rotates downwards to achieve the unloading function. After the material at the valve core 11 end is unloaded, the weight of the pressing component causes the valve core 11 to reclose and reset, repeating this cycle to achieve automatic unloading. When the weight of the pressing component is fixed, the weight of each unloaded material can be calculated using the lever principle, and since the weight of the unloaded material is fixed each time, a metering function is achieved.

[0031] Specifically, a connecting flange 2 is fixedly connected to the top of the housing 1, and the connecting flange 2 is used to connect the housing 1 and the feed cylinder.

[0032] It should be noted that the connecting flange 2 is connected to the flange of the feed cylinder by bolts, thereby fixing the housing 1 to the bottom of the feed cylinder.

[0033] Specifically, the rotating component includes a lever rotating shaft 9 that is inserted into the bottom of the rotating bracket 8, and the lever rotating shaft 9 is inserted into the middle of the connector 10.

[0034] It should be noted that a groove is provided in the middle of the connector 10 so that the rotating bracket 8 can pass through the middle of the connector 10. The cross-section of the lever rotating shaft 9 is set to I-shape so that the lever rotating shaft 9 connects the connector 10 and the rotating bracket 8, so that the connector 10 can rotate at the bottom of the rotating bracket 8.

[0035] Specifically, the pressing component includes a mounting hole 4 opened on the top of the counterweight frame 3, a counterweight 7 is inserted and connected inside the mounting hole 4, and a load-bearing component 5 and a fastener 6 are provided in the middle of the counterweight frame 3 for fixing the position of the counterweight 7.

[0036] It should be noted that the load-bearing component 5 and fastener 6 connect the counterweight 7 to the counterweight frame 3, and the number of counterweights 7 can be adjusted according to the required quantity.

[0037] Specifically, the load-bearing component 5 includes a load-bearing rod 502 that is inserted and connected to one side of the counterweight frame 3. The counterweight 7 has a load-bearing hole 501 in the middle. The load-bearing rod 502 is inserted and connected inside the load-bearing hole 501. One end of the load-bearing rod 502 is threaded with a load-bearing nut 503.

[0038] It should be noted that the load-bearing rod 502 is T-shaped. It is inserted into the counterweight frame 3 through the load-bearing rod 502. The T-shaped design prevents the rod from completely passing through the counterweight frame 3. When it is necessary to fix the position of the load-bearing rod 502, first pass one end of the load-bearing rod 502 through the counterweight frame 3 so that the other end of the load-bearing rod 502 fits against the counterweight frame 3. Finally, the position of the load-bearing rod 502 is fixed by the load-bearing nut 503.

[0039] Specifically, the fastener 6 includes a fastening rod 602 that is inserted and connected to one side of the counterweight frame 3. A fastening hole 603 is provided on one side of the counterweight 7. The fastening rod 602 is inserted and connected inside the fastening hole 603. A fastening nut 601 is threaded onto one end of the fastening rod 602.

[0040] It should be noted that the fixing method of the fastening rod 602 is the same as that of the load-bearing rod 502, and the multiple fastening rods 602 are parallel to the load-bearing rod 502. The counterweight 7 is restricted to the inside of the mounting hole 4 by multiple parallel rods with fixed positions, thus preventing the counterweight 7 from rotating.

[0041] Furthermore, when using it:

[0042] The first step is to fabricate an automatic unloading metering valve according to the dimensions of the unloading cylinder flange on site, and then connect the connecting flange 2 to the unloading cylinder flange with bolts.

[0043] The second step involves adjusting the weight of a suitable counterweight 7 according to actual production conditions, installing it on the load-bearing component 5, and fixing the position of the counterweight 7 with fasteners 6. The theoretical value Q1 for a single feeding is then calculated using the lever torque principle.

[0044] The third step is to check the sealing condition of the unloading valve in its initial state and the pre-tightening force between the valve core 11 and the housing 1.

[0045] Fourth step, check the smoothness of the rotation of lever rotation shaft 9. There should be no jamming, and it should be able to rotate flexibly.

[0046] The fifth step is to perform the material unloading operation, and weigh and measure the amount of material unloaded in a single operation as Q2;

[0047] The sixth step is to compare the values ​​of Q1 and Q2, conduct analysis and adjustments, control the error between the two within a reasonable range, and finally put the automatic unloading metering valve into formal use.

[0048] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
