[0025] 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.
[0026] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.
[0027] like Figure 1-3 As shown, an automatic feeding device for a stone mill flour machine includes:
[0028] Support frame 1;
[0029] The storage system 2 includes a plurality of spring shock absorbers 21 fixedly connected to the support frame 1. A vibrating storage mechanism 22 is fixedly connected to one end of the plurality of spring shock absorbers 21 away from the support frame 1. A sensing mechanism 23 is provided inside the vibrating storage mechanism 22.
[0030] The conveying system 3 is located below the vibrating storage mechanism 22. The conveying system 3 includes a screw conveyor 31 that is connected to the vibrating storage mechanism 22. The screw conveyor 31 is fixedly connected to the support frame 1.
[0031] Grinding system 4 is located on the side of conveying system 3 away from storage system 2, and a weighing meter 41 is installed on one side of grinding system 4;
[0032] The control system is electrically connected to the sensing mechanism 23 and the weighing meter 41.
[0033] The sensing mechanism 23 is used to sense the amount of flour raw material in the vibrating storage mechanism 22 to determine whether it needs to be added. When it needs to be added, the flour raw material can be lifted by an external tool (such as a lifting platform truck) and put into the vibrating storage mechanism 22. The vibrating storage mechanism 22 can prevent clogging caused by adhesion and agglomeration. The spring shock absorber 21 is designed to reduce the impact of mechanical vibration on the support frame 1 and extend the service life of the equipment. The weighing meter 41 can weigh the flour and dregs discharged from the grinding system 4. When the weight of the flour and dregs measured by the weighing meter 41 is the same as the added flour raw material, the signal is transmitted to the control mechanism. The control mechanism uses the screw conveyor 31 to transport the raw material. The screw conveyor 31 is located below the vibrating storage mechanism 22 and receives the material falling due to vibration. It can transport the flour raw material to the grinding system 4 in a timed and quantitative manner. The grinding system 4 grinds the flour raw material to obtain the final flour required.
[0034] In a further optimized design, the sensing mechanism 23 is an infrared sensor, which includes a transmitter and a receiver, located on both sides of the vibrating storage mechanism 22.
[0035] Furthermore, the sensing mechanism 23 uses an infrared sensor. The transmitting tube and receiving tube of the infrared sensor are respectively installed on both sides of the vibrating storage mechanism 22. When the flour raw material blocks the infrared beam, the receiving end signal is interrupted, and there is no need to add flour raw material. When the infrared beam is transmitted to the receiving tube, a signal is transmitted to the control system, indicating that flour raw material needs to be added into the vibrating storage mechanism 22.
[0036] Further optimization of the scheme: the vibrating storage mechanism 22 includes a storage hopper 221 fixedly connected to the end of the spring damper 21 away from the support frame 1. The top of the storage hopper 221 is connected to the feed pipe 223, the bottom of the storage hopper 221 is connected to the first discharge pipe 224, a vibrating motor 222 is fixedly connected to one side of the storage hopper 221, and a transmitting pipe and a receiving pipe are fixedly connected to both sides of the storage hopper 221 respectively.
[0037] The vibrating motor 222 drives the storage hopper 221 to vibrate, preventing the flour raw materials inside from sticking together and clumping, which can cause blockages. The feed pipe 223 is used to feed the flour raw materials, and the first discharge pipe 224 is used to transport the flour raw materials into the screw conveyor 31.
[0038] Further optimization of the scheme: the screw conveyor 31 includes a feeding pipe 311, which is fixed to the support frame 1. A feed inlet 312 is provided at the upper end of one side of the feeding pipe 311, which is correspondingly set with the first discharge pipe 224. A discharge outlet 313 is provided at the bottom end of the feeding pipe 311 away from the first discharge pipe 224. The discharge outlet 313 is connected to the grinding system 4. A conveying component 314 is provided inside the feeding pipe 311.
[0039] The flour raw material enters the feed pipe 311 through the feed inlet 312, and is conveyed by the conveying component 314 and enters the grinding system 4 through the discharge outlet 313.
[0040] In a further optimized design, the conveying assembly 314 includes a partition 3141 fixed inside the feeding pipe 311. A motor 3142 is installed on one side of the partition 3141. The output shaft of the motor 3142 passes through the partition 3141 and is connected to a spiral shaft 3143. A spiral blade 3144 is fixed on the spiral shaft 3143.
[0041] The partition 3141 is used to block the motor 3142 and the flour raw material. When the motor 3142 is turned on, it drives the spiral shaft 3143 to rotate, and the spiral blades 3144 fixed on it rotate accordingly. During this process, the flour raw material in the feed port 312 is transported to the discharge port 313. Since the speed of the motor 3142 is constant and the spiral blades 3144 are evenly distributed, the flour raw material can be transported in a timely and quantitative manner.
[0042] In a further optimized design, the discharge port 313 is connected to a second discharge pipe 315, and a solenoid valve 316 is installed on the second discharge pipe 315. The solenoid valve 316 is electrically connected to the control system.
[0043] The control system controls the opening and closing of the solenoid valve 316 to control whether the flour raw materials inside are transferred to the grinding system 1.
[0044] Further optimization of the scheme: the grinding system 4 includes a grinding body 42 connected to the second discharge pipe 315. The side wall of the grinding body 42 is provided with a surface discharge pipe 43 and a slag discharge pipe 44. A weighing meter 41 is provided on one side of the grinding body 42. A collection box 45 is provided on the weighing meter 41. The collection box 45 is located below the surface discharge pipe 43 and the slag discharge pipe 44.
[0045] The grinding body 42 includes an upper grinding disc, which is driven to rotate by a drive motor and has radial or spiral grinding teeth engraved on its surface; a lower grinding disc, which is fixed and whose grinding teeth match the upper grinding disc to form a grinding gap; and an internal air-powered sorting mechanism that separates the ground flour and bran, and discharges them into a collection box 45 through a flour discharge pipe 43 and a slag discharge pipe 44. Baffles (not labeled in the figure) are installed between the collection boxes 45. A weighing scale 41 is used to weigh the material in the collection box 45. When the value is consistent with the flour raw material conveyed by the screw conveyor 31, a signal is sent to the control system to open the solenoid valve 316 and start the motor 3142 to convey the flour raw material.
[0046] Working principle:
[0047] When the flour material blocks the infrared beam, the receiver signal is interrupted, and no flour material needs to be added. When the infrared beam reaches the receiver tube, it sends a signal to the control system, indicating that flour material needs to be added to the storage hopper 221. When it is necessary to add the flour material, simply use an external tool (such as a lifting platform vehicle) to lift the flour material and put it into the storage hopper 221.
[0048] The material in the collection box 45 is weighed using a weighing scale 41. When the value is consistent with the flour raw material conveyed by the screw conveyor 31, a signal is sent to the control system to open the solenoid valve 316 and start the motor 3142 to convey the flour raw material. When the value is inconsistent with the flour raw material conveyed by the screw conveyor 31, no conveying is required.
