Description

The double servo bulking systems of twin-tub

Technical field

The utility model belongs to bulking system technical field, is used for material-filling, and in particular to a kind of double servos fillings of twin-tub Dress system.

Background technique

Existing filling structure is that single servo motor drives one piece of lifter plate to drive piston lifting to realize suction and tank material, this Kind traditional mode is using servo motor band two or more piston cylinders, this maximum shortcoming of canning means It is exactly it is difficult to ensure that every bottle of filling weight come out is in critical field.

The factor for influencing filling amount is as follows:

The first, the inner hole precision of piston cylinder has a deviation, the more big filling weight come out of deviation more is difficult to unified fiducial mark；

The second, material fluidity is poorer, i.e., using this suction mode in high speed suction once in a while will sucked vacuum, lack Few material.

Filling structure in the prior art is not strong using the versatility of in-line arrangement multi-cylinder structure:

The first, when replacing different size doleiform, need to adjust the position of filling head, head number to be more difficult to adjust；

The second, replacement supplies cleaner is cumbersome, to reach cleaning standard, requires disassembly cylinder bucket, the equipment of multi-cylinder is all Second level storage tank is installed additional on cylinder bucket, the cylinder bucket under dismantling will also take alcohol foam washing to reach raw in addition to being rinsed with clear water The disinfection standard of production, second level storage tank also need to clean, and the scavenging period of this multi-cylinder lacks then half a day, more then times Replace material.So the most suitable single variety batch of the production of this multi-cylinder is canned, it is canned to be not suitable for multi items.

Third, the row side formula of this multi-cylinder may be only available for round vase, square vase, the big mouth bottle in bottom, the big bottom in upper end it is small or Special-shaped bottle small in ends broad in the middle cannot achieve filling.Principle explanation: this multiple casing is filling when first bottle gear is first A can leans against on previous bottle (i.e. abutting two-by-two) in the following, subsequent bottle is fed forward one by one, since bottom is small, leans against Bottle together slightly tilts, and the bottle of the overwhelming majority will be made to topple over.

In addition to it is above-mentioned it is mentioned it is insufficient other than, it is the problem of there is also production capacity and costs, specific as follows:

The filling principle of multi-cylinder seem can because cylinder is more and efficiency can improve, in fact this effect less, such as 8 bottles of front filling After the completion of dress, gear bottle bar is opened, and it is filling again in place that bottle is fed forward to 8 empty bottles next on the conveyor line, this 8 bottles Traveling time if not production capacity cannot be improved well quickly, if mobile quickly, behind put the work of bottle cap Position just needs once plus two to three people are covered to put to guarantee to produce continuous productive process, and cost of labor once added, and per capita output value reduces.

Utility model content

In order to solve the above problems existing in the present technology, the utility model aim is to provide a kind of double servos fillings of twin-tub Dress system solves filling structure in the prior art in suction, is easy sucked vacuum, it is difficult to guarantee every bottle of filling weight come out Measure the problem in a critical field.

The technology employed by the present utility model is

A kind of double servo bulking systems of twin-tub, including shell and filling head, are provided with single charging, double dischargings dress in shell It sets, is matched with control device and realize the double servo filling apparatus of the twin-tub of suction and tank material, and the single charging of control, double dischargings dress Set the PLC controller with the double servo filling apparatus work of twin-tub；

Single charging, double discharging devices include a feed inlet and two filling discharge ports, feed inlet and filling discharging It is respectively arranged with import check valve at mouthful and outlet is unidirectional；

The double servo filling apparatus of the twin-tub include two one servo filling apparatus of a cylinder, feed inlet respectively with two cylinders One servo filling apparatus is connected to or is closed by import check valve, and two filling discharge ports are filling with one servo of a cylinder respectively Device is closed or is connected to by Outlet check valves, is connected separately with a filling head on two filling discharge ports.

Further, the one servo filling apparatus of a cylinder include piston cylinder, the mounting base for installing piston cylinder, setting exist Piston in piston cylinder, across the piston mandril that mounting base is connected with piston, be arranged under mounting base and match with piston mandril The ball screw of conjunction and bearing block for installing ball screw, and control piston mandril move up and down on ball screw Servo motor.

Further, the feed inlet is charging three-port structure, and charging three-port structure is herringbone, T font or enters in font One kind.

Further, two discharge ends of the charging three-port structure are each provided with an import check valve.

Further, stainless steel sanitation-grade fast-assembling is used between the piston cylinder and mounting base, piston cylinder and import check valve Clip mounting means.

Further, it is characterised in that: the piston is connect with piston mandril using T-slot formula.

Further, be additionally provided in the shell and shell be divided into bilevel partition, the mounting base setting every On plate, piston cylinder is placed in the intracorporal upper layer of shell by setting in mounting base, and bearing block is arranged in the intracorporal lower layer of shell, ball wire Bar one end is arranged on bearing block, and the other end passes through partition, and piston mandril one end is after partition and mounting base and in piston cylinder Piston be connected, the other end is placed in shell lower layer and matches with ball screw.

It further, further include a copper sheathing, copper sheathing one end is mounted on partition, and the other end is mounted in mounting base, on copper sheathing It is provided with a pilot hole and piston mandril cooperates, the ball screw across partition one end is placed in pilot hole.
