The driving roller and the driven roller are horizontally and rotatably arranged between the two side plates. The driving roller and the driven roller are perpendicular to the side plates and are equal in distance with the bottom plate. A conveying belt is matched between the driving roller and the driven roller in a rotating mode, and a plurality of through grooves are uniformly formed in the conveying belt. Two sealing boxes with top openings are fixedly arranged between the two side plates. The top of the sealing box is in a horizontal state and is matched with the inner side surface of the conveying belt. The bottom of the sealing box is fixedly provided with an air pump communicated with the inside of the sealing box. A first motor is fixedly mounted on the outer side wall of one side plate, and the output end of the first motor is fixedly connected with the driving roller. After the small bottles to be filled are placed on the conveying belt, air is pumped out of the sealing box through the air pump, so that the air pressure in the sealing box and the through groove above the sealing box is reduced, and the small bottles are tightly pressed on the conveying belt through the air pressure. A first motor drives a driving roller to rotate, and the driving roller drives a conveying belt and a driven roller to move; as the conveyor belt moves, the vials move with it. With the intermittent operation of the first motor, the vials intermittently move following the conveyor belt.

And a filling mechanism and a capping mechanism are respectively arranged between the two side plates corresponding to the positions above the two sealing boxes. The filling mechanism comprises a liquid storage tank fixedly installed between two side plates through a connecting plate, and a square groove which penetrates through the liquid storage tank is formed in the middle of the bottom plate of the liquid storage tank. A liquid inlet is formed in the side wall of the liquid storage tank, and a sealing plug is detachably mounted at the liquid inlet.

A supporting bar is horizontally and fixedly arranged on the inner wall of the guide sleeve, and a first spring is vertically connected between the upper surface of the supporting bar and the bottom surface of the lifting plate. An L-shaped groove communicated with the guide sleeve and the square groove is formed in the bottom plate of the liquid storage tank. The horizontal section of L type groove sliding fit has the horizon bar, and the gyro wheel is installed in the rotation of horizon bar outer end. And the two symmetrical side walls of the square groove are respectively and fixedly provided with a supporting block and a first sealing block. The supporting block is positioned above the roller.

The clamp plate promotes the lifter plate and moves down, compresses the air in the L type groove when the lifter plate compresses first spring. The compressed air pushes the horizontal rod and the roller to move horizontally outwards, the roller pushes the second sealing block and the vertical rod to move upwards, and the second sealing block compresses the second spring; the second sealing block is separated from the first sealing block, and the square groove is opened. The modified aliphatic water reducing agent solution in the liquid storage tank is synchronously extruded when the pressing plate moves downwards, and the compressed modified aliphatic water reducing agent solution is sprayed out through the opened square groove and enters small bottles on the conveying belt below.

And a third spring is vertically arranged between the upper surface of the sealing plate and the lower surface of the storage box top plate. Before working, the third magnet block, the sliding rod and the sealing plate are pushed downwards to stretch the third spring. Manually open in pushing the storage case in proper order with the lid of vial after the check valve, then loosen the slide bar, drive third magnet piece, slide bar and closing plate rebound through the elastic force effect of third spring for atmospheric pressure reduces between closing plate and the superiors lid, thereby presses the lid in the storage case through atmospheric pressure effect, avoids lid free fall. The mounting disc and the second magnet block are driven to rotate continuously by the second motor, when the second magnet block moves to a position right above the third magnet block, mutual repulsion force is generated between the second magnet block and the third magnet block, the sliding rod and the sealing plate are pushed to move downwards by the action of the mutual repulsion force, in the process, the one-way valve is in a closed state, so that the air pressure between the sealing plate and the cover at the uppermost layer is increased, and the cover at the lowermost layer is pressed out of the material storage box under the action of the air pressure; the lid leaving the magazine falls to the vial opening. When the second magnet block leaves the position right above the third magnet block, the mutual repulsion force between the second magnet block and the third magnet block disappears, the third magnet block, the sliding rod and the sealing plate are driven to move upwards under the action of the elastic force of the third spring, and in the process, the one-way valve is in an open state; the external air enters between the sealing plate and the uppermost cover through the vent groove, and the air pressure between the sealing plate and the uppermost cover is restored to the initial state.
