Description

Technical Field

[0001] The present invention relates to the field of automated feeding, and specifically to an automated feeding system. Background Art

[0002] Ammonium sulfate and sodium bicarbonate are two common chemical substances, which have a wide range of applications in multiple fields. Ammonium sulfate is an inorganic salt with the chemical formula (NH4)2SO4; it is a white crystalline powder, soluble in water, and insoluble in ethanol and acetone. Ammonium sulfate is stable at room temperature but decomposes at high temperatures. Sodium bicarbonate, also known as baking soda, has the chemical formula NaHCO3. It is a white fine crystal with a solubility in water less than that of sodium carbonate and is weakly alkaline.

[0003] In the existing production and processing of chemical products, baking soda is needed for the production of food additives, and ammonium sulfate is used as a raw material for the production of agricultural fertilizers. Moreover, both of these materials are powdery raw materials. During the actual production process, when adding powdery materials to a reaction vessel, quantitative addition is required. When quantitatively adding powdery raw materials in the existing method, the powdery raw materials are introduced into a weighing container through a discharge pipe and then into the reaction container. However, when the discharge pipe introduces the powdery raw materials into the weighing container, the situation of powder scattering easily occurs, resulting in waste and making it inconvenient to collect the scattered powder after discharging. Therefore, new technical solutions need to be designed to solve this problem. Summary of the Invention

[0004] The purpose of the present invention is to provide an automated feeding system to solve the problems raised in the background art.

[0005] To achieve the above purpose, the present invention provides the following technical solution: An automated feeding system includes a storage tank, the tail end of the storage tank is fixedly communicated with a discharge pipe, and the top of the storage tank is detachably connected with a cover plate;

[0006] A cylinder is arranged below the discharge pipe. The cylinder is fixedly installed on the top of a high-precision weighing device, and the bottom of the high-precision weighing device is connected with a carrier plate. The cylinder is a double-layer sandwich structure, an annular filter plate is embedded in the inner wall of the cylinder, a pumping and filling dual-purpose air pump is fixedly installed on the outer wall of the cylinder, and both ends of the pumping and filling dual-purpose air pump are fixedly communicated with a conduit, and the conduit is communicated with the cylinder cavity;

[0007] An adjusting plate is arranged on one side of the cylinder, and one side of the adjusting plate is connected with the carrier plate through a rotating assembly.

[0008] By adopting the above technical solution, first, the adjusting plate rotating assembly moves, so as to drive the cylinder body to move to the lower side of the discharge pipe. Then, the discharge pipe is used for discharging, and the material is introduced into the inner cavity of the cylinder body. Then, a high-precision weighing device is used for weighing. During the discharging process, the powder will float. When the weighing is completed, the charging and discharging dual-purpose air pump is started to make the clamping cavity of the cylinder body form a negative pressure. As a result, negative pressure will be generated in the fine holes on the annular filter plate, which can generate a traction force on the upward-diffusing material, so that the floating material can be adsorbed on the surface of the annular filter plate. This is beneficial to avoid the waste caused by the powder material floating to other places, and is beneficial to avoid the influence of insufficient material on the mixing effect during processing. After accurate weighing, the adjusting plate drives the rotating assembly to move, moves the cylinder body to the designated position, and then the rotating assembly drives the carrier plate to rotate, so that the cylinder body is turned over, and the material is poured out.

[0009] As a preferred embodiment of the present invention, a plurality of uniformly distributed springs are fixed at the top of the clamping cavity of the cylinder body, and a ring body is arranged at the lower side of the clamping cavity of the cylinder body.

[0010] By adopting the above technical solution, when the cylinder body is turned over to export the material, the ring body will drop and impact on the spring, generating up and down vibrations. At the same time, the charging and discharging dual-purpose air pump inflates the inner cavity of the cylinder body at this time, so that the gas acting on the surface of the ring body can intensify its vibration, and the vibration is transmitted to the annular filter plate, which can shake off the powder material attached to its surface and make it exported together. This is beneficial to improve the completeness of discharging and is beneficial to further avoid the influence of residual material on the mixing of materials during processing.

[0011] As a preferred embodiment of the present invention, an electric push rod is fixedly installed at the middle of the bottom of the carrier plate, and the push rod of the electric push rod penetrates through the carrier plate and is fixedly connected to the bottom of the high-precision weighing device.

[0012] By adopting the above technical solution, when the material is introduced into the inner cavity of the cylinder body by the discharge pipe, the electric push rod drives the high-precision weighing device to lift, so that the cylinder body is lifted, and then the discharge pipe is inserted deep into the inner cavity of the cylinder body, so that the material can be accurately introduced into the inner cavity of the cylinder body, and the material is located under the annular filter plate for discharging. Therefore, when the material diffuses and is adsorbed, it is beneficial to avoid affecting the lower material.

[0013] As a preferred embodiment of the present invention, limiting rods are fixed on both sides of the bottom of the high-precision weighing device, and the limiting rods movably penetrate through the carrier plate.

[0014] By adopting the above technical solution, the setting of the limiting rods makes the lifting and lowering stability of the electric push rod driving the high-precision weighing device high.

[0015] As a preferred embodiment of the present invention, a sliding cavity is formed on one side wall of the adjusting plate. A lead screw motor is fixedly installed at one end of the sliding cavity. The outer end of the transmission shaft of the lead screw motor is fixedly connected with a lead screw. The outer end of the lead screw is rotationally connected to the inner wall of the sliding cavity. A suitable lead screw slider is sleeved on the outer wall of the lead screw, and the outer wall of the lead screw slider is connected to the rotating assembly.

[0016] By adopting the above technical solution, the lead screw is driven to rotate by the lead screw motor, so as to drive the lead screw slider to move, thereby driving the rotating assembly to move, and further driving the cylinder to move.

[0017] As a preferred embodiment of the present invention, the rotating assembly includes a fixed block, which is fixedly connected to the lead screw slider. An installation groove is formed on the outer wall of the lead screw slider. A drive motor is fixedly installed in the inner cavity of the installation groove. The outer end of the transmission shaft of the drive motor is fixedly connected with a connecting block, and the connecting block is fixedly connected to the carrier plate.

[0018] By adopting the above technical solution, the drive motor can drive the connecting block to rotate, so as to drive the carrier plate to rotate, and further drive the cylinder to flip.

[0019] As a preferred embodiment of the present invention, a bearing is fixedly sleeved on the upper side of the outer wall of the rotating shaft. Connecting rods are fixed on both side walls of the bearing, and the top of the connecting rod is fixedly connected to the bottom of the cover plate.

[0020] By adopting the above technical solution, the setting of the bearing makes the rotation of the rotating shaft highly stable.

[0021] As a preferred embodiment of the present invention, a servo motor is fixedly installed on the top of the cover plate. The transmission shaft of the servo motor penetrates through the cover plate and is fixedly connected with a rotating shaft. The tail end of the rotating shaft is fixedly connected with an auger, and the auger is inserted into the discharge pipe.

[0022] By adopting the above technical solution, during discharging, the servo motor drives the rotating shaft to rotate, so as to drive the auger to rotate in the discharge pipe, thereby realizing the discharge of materials.

[0023] As a preferred embodiment of the present invention, mounting plates are fixedly provided on the outer walls at both ends of the adjusting plate.

[0024] By adopting the above technical solution, the setting of the mounting plates makes it convenient to install and fix the adjusting plate.

[0025] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0026] In the present invention, when receiving materials, the discharge pipe is inserted into the lower side of the inner cavity of the cylinder. When the materials are introduced into the cylinder, there will be a slight diffusion of the materials. Thus, after the precise weighing is completed, the powder materials continue to diffuse. A negative pressure is generated in the double-layer clamping cavity of the cylinder by a dual-purpose air pump for pumping and filling. As a result, a negative pressure will be generated in the fine holes on the annular filter plate, which can generate a traction force on the materials diffusing upward, so that the scattered materials can be adsorbed on the surface of the annular filter plate. This is conducive to avoiding the waste caused by the powder materials drifting to other places and the situation where the lack of materials affects the proportioning effect during processing.

[0027] When the cylinder is flipped to discharge the materials, the ring body will drop and impact on the spring, generating up and down vibrations. At the same time, the dual-purpose air pump for pumping and filling inflates the inner cavity of the cylinder at this time, so that the gas acting on the surface of the ring body can intensify its vibration. The vibration is transmitted to the annular filter plate, which can shake off the powder materials attached to its surface and discharge them together. This is conducive to improving the completeness of discharging and further avoiding the influence of residual materials on the proportioning of materials during processing.

[0040] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0041] In the description of the present invention, it should be understood that the orientation or positional relationships indicated by the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc. are based on the orientation or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present invention.

[0042] In the description of the present invention, it should be noted that unless otherwise clearly specified and limited, the terms "installed", "connected", and "set" should be understood in a broad sense. For example, they can be fixedly connected and set, or detachably connected and set, or integrally connected and set. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific situations. The models of the electrical appliances provided in the present invention are only for reference, and different models of electrical appliances with the same function can be replaced according to actual use conditions.

[0043] Please refer to Figure 1-6 , the present invention provides a technical solution: an automatic feeding system, including a storage tank 1, the tail end of the storage tank 1 is fixedly connected and communicated with a discharge pipe 11, and the top of the storage tank 1 is detachably connected with a cover plate 12;

[0044] A cylinder body 3 is arranged below the discharge pipe 11, the cylinder body 3 is fixedly installed on the top of a high-precision weighing device 21, the bottom of the high-precision weighing device 21 is connected with a carrier plate 2, the cylinder body 3 is a double-layer sandwich structure, an annular filter plate 33 is embedded on the inner wall of the cylinder body 3, a dual-purpose air pump 31 for pumping and filling is fixedly installed on the outer wall of the cylinder body 3, both ends of the dual-purpose air pump 31 for pumping and filling are fixedly connected and communicated with a conduit 32, and the conduit 32 is communicated with the sandwich cavity of the cylinder body 3;

[0045] An adjusting plate 4 is arranged on one side of the cylinder body 3, and one side of the adjusting plate 4 is connected with the carrier plate 2 through a rotating assembly.

[0046] It should be understood that during actual use, first, the adjusting plate 4 drives the rotating assembly to move, so as to drive the cylinder body 3 to move to the lower side of the discharge pipe 11. Then, the discharge pipe 11 is used for discharging, and the material is introduced into the inner cavity of the cylinder body 3. Then, the high-precision weighing device 21 is used for weighing. During the discharging process, the powder will float. When the weighing is completed, the charging and discharging dual-purpose air pump 31 is started to make the clamping cavity of the cylinder body 3 form a negative pressure. As a result, negative pressure will be generated in the fine holes on the annular filter plate 33, which can generate a traction force on the upward diffusing material, so that the floating material can be adsorbed on the surface of the annular filter plate 33. This is beneficial to avoid the waste caused by the powder material floating to other places and to avoid the influence of insufficient material on the mixing effect during processing. After accurate weighing, the adjusting plate 4 drives the rotating assembly to move, moves the cylinder body 3 to the designated position, and then the rotating assembly drives the carrier plate 2 to rotate, so that the cylinder body 3 is turned over, and the material is thus poured out.

[0047] Furthermore, mounting plates are fixed on the outer walls at both ends of the adjusting plate 4. The setting of the mounting plates facilitates the installation and fixation of the adjusting plate 4.

[0048] Even further, a servo motor 13 is fixedly installed on the top of the cover plate 12. The transmission shaft of the servo motor 13 penetrates through the cover plate 12 and is fixedly connected to a rotating shaft 14. A auger 15 is fixedly connected to the tail end of the rotating shaft 14, and the auger 15 is inserted into the discharge pipe 11;

[0049] It should be understood that during discharging, the servo motor 13 drives the rotating shaft 14 to rotate, which can drive the auger 15 to rotate in the discharge pipe 11, so as to discharge the material.

[0050] It is worth introducing that a bearing 16 is fixedly sleeved on the upper side of the outer wall of the rotating shaft 14. Connecting rods are fixed on both side walls of the bearing 16, and the top of the connecting rod is fixedly connected to the bottom of the cover plate 12. The setting of the bearing 16 makes the rotation of the rotating shaft 14 highly stable.

[0051] As Figure 1 and 6 shown; a plurality of evenly distributed springs 34 are fixed on the top of the clamping cavity of the cylinder body 3, and a ring body 35 is arranged on the lower side of the clamping cavity of the cylinder body 3;

[0052] It should be understood that when the cylinder body 3 is turned over to discharge the material, the ring body 35 will drop and impact on the springs 34, resulting in up and down vibrations. At the same time, the charging and discharging dual-purpose air pump 31 inflates the inner cavity of the cylinder body 3 at this time, so that the gas acting on the surface of the ring body 35 can intensify its vibration. The vibration is transmitted to the annular filter plate 33, which can shake off the powder material attached to its surface and discharge it together. This is beneficial to improve the completeness of discharging and further avoid the influence of residual material on the material ratio during processing.

[0053] As Figure 1and 3 As shown in the figure; an electric push rod 22 is fixedly installed at the middle of the bottom of the carrier plate 2, and the push rod of the electric push rod 22 penetrates through the carrier plate 2 and is fixedly connected to the bottom of the high-precision weighing device 21;

[0054] It should be understood that when the material is introduced into the inner cavity of the cylinder body 3 by using the discharge pipe 11, the electric push rod 22 drives the high-precision weighing device 21 to lift, so that the cylinder body 3 is lifted, and then the discharge pipe 11 is inserted deep into the inner cavity of the cylinder body 3, so that the material can be accurately introduced into the inner cavity of the cylinder body 3, and the material is discharged below the annular filter plate 33. Therefore, when the material diffuses and is adsorbed, it is beneficial to avoid affecting the lower material.

[0055] Furthermore, limit rods 23 are fixedly installed on both sides of the bottom of the high-precision weighing device 21. The limit rods 23 penetrate through the carrier plate 2 movably. The setting of the limit rods 23 makes the lifting and lowering stability of the electric push rod 22 driving the high-precision weighing device 21 high.

[0056] As Figure 1 and 5 shown in the figure; a sliding cavity is opened on one side wall of the adjusting plate 4. A screw motor 44 is fixedly installed at one end of the sliding cavity. The outer end of the transmission shaft of the screw motor 44 is fixedly connected with a screw rod 45. The outer end of the screw rod 45 is rotationally connected with the inner wall of the sliding cavity. A suitable screw slider 46 is sleeved on the outer wall of the screw rod 45, and the outer wall of the screw slider 46 is connected with a rotating component;

[0057] It should be understood that by driving the screw rod 45 to rotate through the screw motor 44, the screw slider 46 can be driven to move, so as to drive the rotating component to move, and then drive the cylinder body 3 to move.

[0058] Furthermore, the rotating component includes a fixed block 41. The fixed block 41 is fixedly connected with the screw slider 46.
