Technical Field

The invention relates to the field of liquid filling production line equipment, in particular to a filling tube device of a liquid filling machine.

Background

The liquid filling machine is mainly used for filling lotion, care solution, oral liquid, disinfectant, eye lotion, nutrient solution, wine, injection, pesticide, medicine, perfume, edible oil, lubricating oil and liquid in special industries. The operation flow is as follows: the boxes filled with the empty bottles are stacked on the tray, are conveyed to the tray unloading machine by the conveyor belt, are unloaded one by one, are conveyed to the box unloading machine along with the conveyor belt, are taken out of the boxes, are conveyed to the box washing machine by the conveyor belt, are cleaned and are conveyed to the side of the box filling machine so as to be filled with the bottles filled with the beverages. The empty bottles taken out from the box unloader are conveyed into a bottle washer by another conveyer belt to be disinfected and cleaned, and then are conveyed into a filling machine and a cap sealing machine after being checked by a bottle checking machine and meeting the cleaning standard. The beverage is filled into bottles by a filling machine. The bottles filled with the beverage are capped and sealed by a capping machine and conveyed to a labeling machine for labeling, and the bottles are conveyed to a box filling machine to be filled into a box after being labeled, conveyed to a tray stacking machine to be stacked on a tray and conveyed to a warehouse.

The working principle of the invention is as follows:

a filling pipe of the liquid filling machine is divided into a main connecting pipe 1 and a branch connecting pipe 3 by an integral pipe, the main connecting pipe 1 is fixedly connected with the liquid outlet end of an automatic filling module of a liquid filling machine body, and the main connecting pipe 1 and the branch connecting pipe 3 are connected through a four-way pipe 2;

when liquid to be filled is sequentially ejected from the main connecting pipe 1, the four-way pipe 2 and the branch connecting pipe 3 into the bottle mouth, the branch connecting pipe 3 inevitably generates vibration due to liquid impact force, the pipe orifice of the branch connecting pipe 3 is influenced to be aligned with the bottle mouth, liquid is splashed out, and raw materials are wasted;

the branch connecting pipe 3 can be a colloid hose or a hard pipe such as a metal pipe, and the adjusting assembly can be applied to the colloid hose or the hard pipe;

as shown in fig. 5-6, when the bottle mouth of the liquid bottle to be filled is near the lower part of the adapter tube 3, the first buffer roller 6 is directly abutted against the bottle mouth of the liquid bottle to be filled, at the moment, the first suction cup 7 is adsorbed on the bottle mouth of the liquid bottle to be filled, so as to play a role in adsorption and fixation, even if the liquid to be filled is sprayed into the bottle mouth from the main connecting pipe 1, the four-way pipe 2 and the branch connecting pipe 3 in sequence, the tap 3 inevitably generates vibrations due to the impact of the liquid, on the one hand, the outer damping sleeve 62 acts as a buffer in the longitudinal direction, and on the other hand, because the first spring 10 extends into the adjusting hole, the first tapping pipe 3 can be abutted against the first spring 10 when generating transverse vibration and finally acts on the first elastic block 12 to play a transverse buffering role, so that the pipe orifice of the first tapping pipe 3 is stably aligned with the bottle opening, liquid is not splashed out, and raw material waste is avoided; the flexible hose is suitable for the colloid hose and also suitable for the hard tube, particularly the colloid hose, and solves the problems of movement and displacement of the colloid hose in guiding out the filling liquid;

when the U-shaped frame groove plate 9 is in the state shown in the figures 5-6, the U-shaped frame groove plate is upwards pinned along the pin rod 15, the suction cup II 18 on the buffer roller II 17 is sucked on the four-way pipe 2, the elastic block II 13 abuts against the pin rod 15, and the spring II 11 is in a compressed state, so that the adjusting assembly part is fixed;

as shown in fig. 1-2, when the bottle mouth of the liquid bottle to be filled is far from the lower part of the dispensing tube 3, the U-shaped frame groove plate 9 is pin-connected downwards along the pin rod 15, the second elastic block 13, the second spring 11, the supporting rod 14, the pin rod 15 and the second buffer roller 17 slide downwards together until the second buffer roller 17 slightly falls below the bottle mouth of the liquid bottle to be filled, and at this time, the metal rod 16 on the second elastic block 13 and the tail end of the elastic sleeve 4 can extend into the adjusting hole 63 (because the metal rod 16 is a thin rod and has a certain elastic deformation elastic sleeve 4), so as to fix the position of the second elastic block 13 and also fix the position of the second buffer roller 17;

then the second buffer roller 17 is directly abutted against the bottle mouth of the liquid bottle to be filled, at this time, the second suction cup 18 is adsorbed on the bottle mouth of the liquid bottle to be filled to play a role of adsorption and fixation, even when the liquid to be filled is sequentially sprayed from the main connecting pipe 1, the four-way pipe 2 and the branch connecting pipe 3 into the bottle mouth, the branch connecting pipe 3 inevitably generates vibration due to liquid impact force, on one hand, the second outer buffer sleeve 172 plays a role of buffering in the longitudinal direction, on the other hand, because the tail ends of the metal rod 16 and the elastic sleeve 4 can extend into the adjusting hole 63, the metal rod 16 and the elastic sleeve 4 are abutted against the first buffer roller 6 when the branch connecting pipe 3 generates transverse vibration, and finally play a role of transverse buffering on the first outer buffer sleeve 62, it is worth mentioning that not only the elastic material of the first outer buffer sleeve 62 plays a role of buffering, the vibration force enables the first buffer roller 6 to roll to absorb a part of the vibration force (as shown in figure 6, the first buffer roller 6 is also abutted against the metal rod 16 and the elastic sleeve 4, and the transverse vibration force in the state can be released to the second elastic block 13 and the second outer buffer sleeve 172), so that the first buffer roller 6 and the adjusting assembly part are actually an integrally matched, interactive and mutually shock-absorbing system, and finally, the pipe orifice of the connecting pipe 3 is stably aligned to the bottle orifice, liquid is not splashed out, and raw material waste is avoided; the flexible hose is suitable for the colloid hose and also suitable for the hard tube, particularly the colloid hose, and solves the problems of movement and displacement of the colloid hose in guiding out the filling liquid;

as shown in fig. 3-4, the heights of the second elastic block 13, the second spring 11, the support rod 14, the pin rod 15 and the second buffer roller 17 can be adjusted according to the height of the bottle mouth, and the tail ends of the metal rod 16 and the elastic sleeve 4 can extend into the adjusting holes 63 with different heights.

When the device applies force to roll the first buffer roller 6 and the second buffer roller 17, the first suction cup 7 and the second suction cup 18 are not adsorbed on the bottle mouth of the liquid bottle to be filled, and the device is exquisite, convenient and fast.

The above description is only for the preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art should be able to cover the technical scope of the present invention and the equivalent alternatives or modifications according to the technical solution and the inventive concept of the present invention within the technical scope of the present invention.
