DETAILED DESCRIPTION
[0020] In order to make the above features and advantages of the present invention more understandable, embodiments are given below with reference to the accompanying drawings for detailed description, but the present invention is not limited thereto.
[0021] refer to Figures 1 to 5
[0022] A quantitative mechanism for reducing material contamination comprises a frame, on which a metering cylinder 20 located on the upper side of a collecting hopper 50 is mounted, a pair of discharge doors 21 driven to open and close by a driving mechanism are arranged at the lower end of the metering cylinder, a protective cover 30 located on the outer side of the discharge door is arranged at the lower part of the metering cylinder, and a protective plate 40 is fixed around the upper end of the collecting hopper to the outer side of the protective cover, so that pollutants are prevented from entering a packaging container through the inside of the collecting hopper by the protective cover and the protective plate.
[0023] In this embodiment, both ends of the discharge door have wing plates 22 located on the outside of the metering cylinder, and fixed frames 23 are installed on the outer walls of both sides of the metering cylinder. The lower part of the fixed frame is rotatably connected to a discharge shaft 24 with one end fixedly connected to the wing plate. The discharge shaft is driven by a driving mechanism to rotate, thereby realizing the opening and closing of a pair of discharge doors.
[0024] In this embodiment, the driving mechanism includes a cylinder, an electric cylinder or an electric push rod 25 vertically installed on the upper end of the fixed frame, and a driving block 26 is fixed to the lower end of the telescopic rod of the cylinder, the electric cylinder or the electric push rod, and a swing arm 27 is fixed to the other end of the discharge shaft, and a connecting rod 28 is hinged on the swing arm. The upper ends of the two connecting rods on the same side are hinged to the corresponding driving blocks, so that a pair of discharge doors can be opened and closed through the telescopic action of the cylinder, the electric cylinder or the electric push rod, thereby completing the opening and closing of the lower end of the metering cylinder.
[0025] In this embodiment, the discharge shaft is welded to the wing plate without using fasteners, and is separated by an isolation cover and an isolation plate to prevent pollutants that may be generated by the power of the discharge door from falling into the collecting hopper.
[0026] In this embodiment, the air cylinder, electric cylinder or electric push rod, drive block, swing arm, and connecting rod are all located outside the protective plate.
[0027] In this embodiment, a feed hopper 10 is disposed at the upper end of the metering cylinder, the lower part of which extends into the metering cylinder and is fixedly connected to the frame, and a feed gate 11 is disposed at the lower end of the feed hopper, which can swing to open and close the lower port of the feed hopper.
[0028] In this embodiment, in order to realize the opening and closing of the feed gate, a feed shaft 13 driven to rotate by a motor 12 is rotatably connected to the frame, and the two ends of the feed gate respectively have connecting plates 14 that turn upward and are located on the outside of the feed hopper, and the upper part of the connecting plate is fixedly connected to the feed shaft.
[0029] Specifically, the upper part of the connecting plate is welded to the feed shaft without using fasteners. The feed shaft can drive the feed gate to rotate to realize the gate opening and closing action; the bearings and power on both sides of the feed shaft are away from the feed hopper to prevent the pollutants they may produce from falling into the metering cylinder.
[0030] In this embodiment, a flow dividing baffle rod 29 is transversely fixed in the lower port of the metering cylinder, and the upper part of the flow dividing baffle rod is a sharp corner.
[0031] Working principle: The material will pass through the inside of the feed hopper, and through the control of the feed gate, it will fall into the inside of the metering cylinder by its own weight for metering, and then through the control of the discharge gate, it will fall into the collection hopper by its own weight and flow out to the packaging container below. In order to prevent the material from being contaminated, isolation measures and other methods are adopted to ensure that there are no fasteners, flexible parts, lubricated components and power components that may generate pollutants above the metering cylinder and the collection port, which effectively reduces the possibility of abrasive particles formed by wear of moving parts, oil stains used for lubrication, accidental loosening of fasteners, damage of flexible parts and other pollutants entering the packaging container through the inside of the collection hopper.
[0032] If the present invention discloses or involves components or structures that are fixedly connected to each other, then, unless otherwise stated, the fixed connection can be understood as: a detachable fixed connection (for example, connection using bolts or screws), and can also be understood as: a non-detachable fixed connection (for example, riveting, welding). Of course, the fixed connection to each other can also be replaced by an integrated structure (for example, manufactured by one-piece molding using a casting process) (except where it is obviously impossible to use an one-piece molding process).
[0033] In addition, unless otherwise stated, the terms used to indicate positional relationships or shapes in any of the technical solutions disclosed in the above utility model include states or shapes that are approximate, similar or close thereto.
[0034] Any component provided by the utility model can be assembled from multiple separate components, or can be a separate component manufactured by an integrated molding process.
[0035] The above description is only a preferred embodiment of the present invention. All equivalent changes and modifications made according to the scope of the patent application of the present invention should fall within the scope of the present invention.
