Detailed Description

The discharging machine comprises a feeding device and a metering discharging device. As shown in fig. 1, the feeding device includes a material tank 9, a feeding motor 11, and a spiral pushing rod (the spiral pushing rod is not shown in the figure), the spiral pushing rod is horizontally disposed in the material tank 9, a side opening (the side opening is not shown in the figure) is disposed on the left side of the material tank 9, and the feeding motor 11 outside the material tank 9 can drive the spiral pushing rod to discharge material toward the side opening at a constant speed. The metering and discharging device is arranged on the left side of the material tank 9, as shown in figures 2-3, the metering and discharging device comprises a metering bin 1 serving as a piston cylinder, a material pressing piston 2, a reciprocating mechanism 12, an opening and closing split cover 4 and two groups of two connecting rods 3, the metering bin 1 is a vertical equal-diameter square tube and comprises a bin releasing port located on the top wall of the metering bin 1 and a discharging bin port 10 located on the bottom wall of the metering bin 1; the pressing piston 2 is in a cuboid shape, and the shape and the size of the stripping bin opening are matched with the cross section of the pressing piston 2, so that the pressing piston 2 can always seal the stripping bin opening, and materials in the metering bin 1 cannot leave the metering bin 1 through the stripping bin opening. The reciprocating mechanism 12 comprises an eccentric wheel 20, a transmission rod 21 and a driving motor (the driving motor is not shown in the figure), the reciprocating mechanism 12 can drive the material pressing piston 2 positioned in the metering bin 1 to do reciprocating lifting motion, a side feeding bin opening 7 is further formed in the side wall of the metering bin 1 on one side of the lifting motion path of the material pressing piston 2, and the side feeding bin opening 7 is communicated with the side opening of the material tank 9. The arc-plate-shaped opening and closing split cover 4 is arranged below the discharging bin opening 10, the opening and closing split cover 4 comprises two split transverse covers 15, and a connecting vertical plate 8 extends upwards from one side of each split transverse cover 15; a horizontal cross column 13 is fixedly arranged on the outer side wall (the side wall far away from the side opening) of the measuring bin 1, the proximal end points of the two groups of two connecting rods 3 are hinged on the same point of a transmission rod 21 of the reciprocating mechanism 12, the distal end points of the two groups of two connecting rods 3 are rotatably arranged on the cross column 13, so that the two groups of two connecting rods 3 form a quadrangle with variable interior angles, the connecting line between the proximal end point and the distal end points is a symmetry axis, and the two groups of two connecting rods and the corresponding cover bodies thereof are mutually symmetrical about the symmetry axis; in addition, the two connecting vertical plates 8 are respectively and correspondingly fixedly connected with the distal end parts of the two connecting rods 3, so that the two connecting rods 3 are fixedly connected with the cover body. An extension plate with a closed groove 14 extends downwards from the other side of the split transverse cover 15, a sliding block 5 which can slide but cannot slip is arranged in the closed groove 14, an arc-shaped guide groove 6 with a circular notch is arranged on one side below the discharging bin opening 10 and is fixedly connected with the material tank 9, and the sliding block 5 is movably arranged in the arc-shaped guide groove 6.

The working process of the discharging machine is as follows: the material feeding device is characterized in that materials are added into a material tank 9 of the feeding device, and the materials in the material tank 9 are conveyed into the metering bin 1 through a side opening of the material tank 9 and a side feeding bin opening 7 of the metering bin 1 by a spiral pushing rod under the driving of a feeding motor 11. The material pressing piston 2 initially hovers at the highest position, as shown in fig. 2, at this time, the material pressing piston 2 slides out of but does not slide out of the stripping bin port of the metering bin 1 and seals the stripping bin port, and the opening and closing split cover 4 is in a closed state and seals the discharge bin port 10 at the bottom wall of the metering bin 1, so that the material conveyed into the metering bin 1 through the side opening gradually fills the metering bin 1; when the metering bin 1 is filled with materials, the transmission rod 21 of the reciprocating mechanism 12 drives the pressing piston 2 to press downwards, the two connecting rods 3 are horizontally and transversely pulled apart (according to the direction of fig. 2) in the process that the transmission rod 21 presses the pressing piston 2, namely, a hinge point in the middle of the two connecting rods 3 horizontally and transversely displaces, so that the split transverse covers 15 are driven by the two connecting rods 3, and therefore the split transverse covers 15 rotate around the transverse columns 13 on the side walls of the metering bin 1 away from each other (if only one group of the two connecting rods 3 and the corresponding split transverse cover 15 are seen, the two connecting rods 3 swing towards one side and the split transverse cover 15 swings towards the other side) so as to open the bin outlet 10; the slide block 5 on the extension plate of the split transverse cover 15 also moves along the arc-shaped guide groove 6, so that the motion track of the split transverse cover 15 is arc-shaped. The material pressing piston 2 passes through the side material inlet bin opening 7 in the process of pressing downwards, the side material inlet bin opening 7 is sealed by the side wall of the material pressing piston 2, finally the piston is pressed downwards to the material outlet bin opening 10, and all materials in the metering bin 1 are pressed downwards through the material outlet bin opening 10 to be discharged into a receiving vessel below the material outlet bin opening 10. Preferably, the distance of the material suction stroke of the material pressing piston 2 in each ascending is the same, and the distance of the material discharge stroke in each pressing is also the same, so that the material pressed out after the material pressing piston 2 completes one reciprocating motion (the reciprocating motion comprises one material suction stroke and one material discharge stroke) is a quantitative material. Preferably, the material may be a sauce.

To ensure that the metering bin 1 is filled with material before each discharge stroke of the material pressing piston 2, a debugging test needs to be performed on the feeding motor 11 first. The reference test method for debugging is as follows: the reciprocating mechanism 12 is set to drive the swaging piston 2 to perform a material sucking stroke and a material discharging stroke with fixed distance at a constant speed at a fixed frequency, so that the effective volume in the metering bin 1 is fixed; the method comprises the steps of setting a feeding motor 11 to drive a spiral pushing rod at an initial frequency, weighing a material extruded to a receiving vessel after a material pressing piston 2 completes a material discharging stroke, if the volume of the material is smaller than the effective volume of a metering bin 1, proving that the metering bin 1 is not filled with the material, starting the material discharging stroke, adjusting the frequency of the feeding motor 11, then carrying out the next material sucking stroke, material discharging stroke, weighing and speed adjusting steps until the volume of the weighed material is equal to the effective volume of the metering bin 1, and ensuring that the material discharging stroke is not carried out after the metering bin 1 is filled with the material by the frequency of the feeding motor 11.
