Description

Variable-diameter filling head

Technical Field

The utility model relates to a filling machinery technical field uses with the supporting use of oils liquid filling machine for the variable footpath filling head of type of taking out in filling fluid.

Background

At present liquid filling equipment, because the filling head can not be adjusted, the filling is single, and the filling head can not carry out the filling to the bottle that the bottleneck span is big, when changing the bottle type, can not adjust, need change a whole set of filling head to under the condition of assurance speed and precision, can't realize the quick filling of the bottle that the bottleneck span is big, can not satisfy the production diversification of enterprise and the needs of convenience.

Disclosure of Invention

The utility model discloses a but reducing filling head through increasing or reducing the export pipe diameter, can realize the quick filling of bottle that the bottleneck span is big under the condition of assurance speed and precision. After the filling is finished, the liquid below the filling head is pumped back to the backflow tank through the backflow pipe, so that the phenomenon of liquid leakage can be avoided.

Therefore, the utility model adopts the technical scheme that:

a variable-diameter filling head comprises a filling fixing plate fixedly connected with a filling device, wherein a filling upper pipe and an air cylinder are fixedly arranged above the filling fixing plate side by side, a filling middle pipe is fixedly arranged below the filling fixing plate, the filling middle pipe is provided with a feeding hole with a side opening and a filling lower pipe with a lower opening, and the feeding hole is communicated with the inner cavity of an oil outlet pipe; a filling piston rod which can be in up-and-down sliding fit with the upper filling pipe and freely shuttles in the filling pipe is arranged in the upper filling pipe in a penetrating manner, the filling piston rod is provided with a suck-back hole which penetrates through the upper filling pipe and the lower filling pipe, the upper end of the filling piston rod is connected with a vacuum generator, and the lower end of the filling piston rod is fixedly connected with a spherical filling inner end enclosure; the part of the filling piston rod outside the filling upper pipe is fixedly connected with the cylinder piston rod through a locking nut and a cylinder connecting plate; the method is characterized in that: the lower end of the filling lower pipe can be in threaded connection with reducing joints with the same outer diameter and different inner diameters, and a conical matching surface matched with the spherical oil nozzle inner end socket is arranged in each reducing joint.

Compared with the prior art, the utility model discloses can connect the reducer union of the same external diameter, different internal diameters very conveniently as required when changing the bottle type, carry out the filling after the quick adjustment, satisfy the big use needs of enterprise's filling bottleneck span. The cylinder and the filling upper pipe adopt a parallel structure, so that the maintenance is convenient; the cylinder and part of the machined parts adopt standard parts, so that the parts are easy to purchase, and a customer can purchase the parts by himself to repair and maintain.

Detailed Description

The variable-diameter filling head shown in the attached drawing comprises a filling fixing plate 7 fixedly connected with a filling device, wherein an upper filling pipe 4 and a cylinder 1 are fixedly arranged above the filling fixing plate 7 side by side, a filling middle pipe 9 is fixedly arranged below the filling fixing plate 7, the filling middle pipe 9 is provided with a feed inlet 10 with a side opening and a filling lower pipe 11 with a lower opening, and the feed inlet 10 is communicated with the inner cavity of the filling lower pipe 11; a filling piston rod 5 which can be in up-and-down sliding fit with the upper filling pipe 4 and freely shuttles in the filling middle pipe 9 penetrates through the upper filling pipe 4, the filling piston rod 5 is provided with a suck-back hole 6 which penetrates through the upper filling pipe and the lower filling pipe, the upper end of the filling piston rod is connected with a vacuum generator, and the lower end of the filling piston rod is fixedly connected with a spherical filling inner end enclosure 8; the part of the filling piston rod 5 outside the filling upper pipe 4 is fixedly connected with the cylinder piston rod through a locking nut 3 and a cylinder connecting plate 2; the method is characterized in that: the lower end of the filling lower pipe 11 can be in threaded connection with reducing joints 12 with the same outer diameter and different inner diameters, and conical matching surfaces matched with the spherical oil nozzle inner end sockets are arranged in the reducing joints 12.

During filling, a cross beam of a filling head fixed by a filling machine descends, when the cross beam reaches a filling position, a cylinder piston rod extends out to drive a filling piston rod connected with the cylinder piston rod to ascend, a filling inner end enclosure ascends along with the filling piston rod, liquid enters a filling middle pipe from a feed inlet and then flows into a bottle body from a discharge outlet of a filling lower pipe, after filling is completed, the cylinder piston rod retracts to drive the filling piston rod connected with the cylinder piston rod to descend, the filling inner end enclosure of the filling piston rod and a conical matching surface of the filling lower pipe are pressed and sealed, liquid does not leak due to the conical matching surface, meanwhile, a control system opens a vacuum generator, and redundant liquid is sucked into a filling piston rod resorption hole and flows into a reflux tank, so. The configured reducer union can meet the filling requirements of different bottle mouths by increasing or reducing the diameter of the outlet pipe.
