Description

Technical Field

[0001] The utility model relates to the technical field of feed processing equipment, in particular to automatic weighing and packaging equipment for a feed premix mixer. Background Art

[0002] Premix is ​​the abbreviation of additive premix feed. It is an intermediate compound feed product made by evenly mixing one or more trace elements (including various trace mineral elements, various vitamins, synthetic amino acids, certain drugs and other additives) with diluents or carriers in the required proportions. After the premix is ​​processed, it needs to be packaged, weighed and transported. Most of the existing packaging processes are manual operations, that is, first put on the feed bag, wait for the premix to be filled, and then transport it to the packaging equipment for packaging and transportation. It is very troublesome, which will not only increase the inconsistency of the premix packaging quality, but also make transportation troublesome.

[0003] For example, Chinese patent publication No. CN212637988U discloses a feed transfer device with a weighing and baling machine. When in use, the feed is fed from the feed feeding funnel and falls into the feed weighing slot through the feed feeding inclined baffle. By reading the reading of the pressure weigher, the feed feeding is stopped when the rated weight is reached, the weighing slot plate fixing screw is loosened, the movable weighing table plate on the right side of the weighing and bagging table is placed in a suitable position, the bag sealing car is pushed to put the packed feed bag into the slot, and then the replaceable power supply fixedly installed inside the bag sealing sleeve fixedly connected to the bag sealing slider is opened, and sewing and packaging are started. After packaging, the bag sealing car is pushed away, and the feed bag locking screw is loosened again, the feed bag is released, and the packaged feed bag is placed on the conveyor belt. By adjusting the height of the fixed bracket, the fixed bracket and the inclined bracket are fixed, and the conveyor belt motor is started to start conveying the packaged feed bag, thereby completing the weighing, packaging and transportation of the feed.

[0004] However, the feed transfer equipment with a weighing and baling machine in the above application has certain limitations. When the feed is put into the hopper, if there is a certain amount of moisture in the feed or water-containing additives are added, the feed may condense into a mass under the action of gravity, thereby blocking the discharge pipe and affecting the discharge of the feed.

[0005] For this reason, we urgently need to provide an automatic weighing and packaging equipment for a feed premix mixer. Utility Model Content

[0006] The purpose of the utility model is to provide an automatic weighing and packaging device for a feed premix mixer, so as to solve the problem that when the feed is put into the hopper of the feed transfer equipment with a weighing and packaging machine proposed in the above-mentioned background technology, if there is a certain amount of moisture in the feed, or water-containing additives are added, the feed may condense into a mass under the action of gravity, thereby blocking the discharge pipe and affecting the discharge of the feed.

[0007] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an automatic weighing and packaging device for a feed premix mixer, comprising a mixer and a support frame, wherein the support frame is fixedly connected to the bottom of the mixer, a mixing device is arranged inside the mixer, and a packaging device is arranged inside the support frame.

[0008] The mixing device comprises a mixing unit, a scraping unit and a feeding unit.

[0009] The mixing unit includes a mixing motor, a mixing shaft, a lifting auger, and a stirring rod. The mixing motor is installed at the top center of the mixer, the mixing shaft is connected to the output end of the mixing motor, two groups of the lifting augers are respectively fixedly connected to the upper and lower ends of the outer surface of the mixing shaft, and two groups of the stirring rods are respectively fixedly connected to the upper and lower ends of the outer surface of the mixing shaft, and are staggered with the lifting augers. Starting the mixing motor drives the mixing shaft to rotate, thereby driving the lifting augers on the outer surface of the mixing shaft to rotate, and the feed inside the mixer is hinged to the top, and the feed is mixed and stirred in cooperation with the stirring rod.

[0010] A further improvement is that the scraper unit includes a connecting rod, a buffer assembly, and a scraper plate. The two connecting rods are respectively fixedly connected to the upper and lower ends of the outer surface of the mixing shaft, and the two groups of buffer assemblies are respectively installed on the outer ends of the connecting rods. The scraper plate is fixedly connected to the outer end of the buffer assembly and is tightly attached to the inner wall of the mixer.

[0011] A further improvement is that the buffer assembly includes a buffer chamber, a flexible spring, and a buffer slide rod. The buffer chamber is opened inside the outer end of the connecting rod, and the flexible spring is installed inside the buffer chamber. The buffer slide rod is fixedly connected to the outer end of the flexible spring and is slidably connected to the inside of the buffer chamber. When the mixing shaft rotates, it drives the connecting rod to rotate, and then drives the scraper plate to rotate to scrape the inner wall of the mixer to avoid waste of resources. When the two are in contact, the thrust generated pushes the buffer slide rod to slide into the buffer chamber and squeeze the flexible spring, thereby buffering through the elasticity of the flexible spring to avoid hard contact between the scraper plate and the inner wall of the mixer, which may cause the scraper plate to break or scratch the inner wall.

[0012] A further improvement is that a feed pipe is fixedly connected to the top right side of the mixer, a discharge pipe is fixedly connected to the bottom center of the mixer, and an electric sealing valve is installed at the bottom of the outer surface of the discharge pipe. By starting the electric sealing valve, the feed can be discharged through the discharge pipe for weighing and packaging.

[0013] A further improvement is that the feeding unit includes a support rod, a motor box, a feeding motor, a rotating shaft, and a feeding auger. The two support rods are respectively fixedly connected to the inner bottom of the mixer, the motor box is installed between the two support rods, the feeding motor is installed inside the motor box, the rotating shaft is connected to the output end of the feeding motor, and its bottom extends into the interior of the discharge pipe, and the feeding auger is fixedly connected to the outer surface of the rotating shaft. When the feed accumulates and condenses into a mass and blocks the discharge pipe, the feeding motor is started to drive the rotating shaft to rotate, thereby driving the feeding auger on the outer surface of the rotating shaft to rotate and discharge the feed, thereby avoiding blockage of the discharge pipe.

[0014] A further improvement is that the packaging device includes a bag-supporting unit and a weighing unit.

[0015] The bag-holding unit includes a mounting seat, an electric lifting rod, a pressing plate, and a bottom support plate. The mounting seat is fixedly connected to the upper left side of the support frame, the electric lifting rod is installed at the bottom of the mounting seat, the pressing plate is fixedly connected to the bottom of the electric lifting rod, and the bottom support plate is fixedly connected to the middle left side of the support frame. The two sides of the packaging bag are respectively placed on the bottom support plate, and then the electric lifting rod is started to move downward, thereby driving the pressing plate to move downward, and cooperating with the bottom support plate to hold the packaging bag open, so as to facilitate unloading and bagging.

[0016] A further improvement is that the weighing unit includes a base and a weighing sensor, the base is installed directly below the mixer, and the weighing sensor is installed at the top center of the base. The feed falls into the packaging bag. When the weight reaches a preset value, the weighing sensor sends an electrical signal and the electric sealing valve closes the discharge pipe, thereby completing the quantitative weighing and packaging of the feed.

[0017] Compared with the prior art, the beneficial effects of the utility model are:
