Abstract
The invention discloses a weighing device of a suspension type electronic quantitative packing scale with all degrees of freedom. The weighing device comprises a weighing container; three fixed seats are respectively arranged at an opening of the weighing container along three directions; the distances among the fixed seats are equal to one another, and the fixed seats are arranged in an equilateral triangle; each fixed seat is provided with a sensor component; the sensor component comprises a sensor bracket; each sensor bracket is provided with a weighing sensor; the lower ends of the sensor brackets are respectively provided with an adjusting connecting rod; the bottom ends of the adjusting connecting rods are respectively provided with a cylindrical horseshoe hanging ring; the cylindrical horseshoe hanging rings are respectively connected and matched with cylindrical pin shafts respectively arranged at the outer ends of the fixed seats; the middle parts of the cylindrical pin shafts are respectively provided with a waist-shaped groove, and the waist-shaped grooves are respectively matched with the cylindrical horseshoe hanging rings; signal output lines of the three weighing sensors are arranged in parallel and then can transmit signals into a controller. According to the weighing device, the cylindrical horseshoe hanging rings are in point contact with the cylindrical pin shafts, so that the frictional force is minimum or can be neglected, the possibility that force is suppressed can not be caused, and the accuracy of weighing is indirectly guaranteed.
Description
Technical field
The present invention relates to a kind of full degree of freedom suspension type electronic quantitative packing scale meausring apparatus, Main Function be remove because of manufacturing errors and feed intake impact the sensor that causes and weighing container suppress the strength defect.
Background technology
Electronic quantitative packing scale impels the constantly progressive and innovation of technology of electronic quantitative packing scale in a large amount of widespread uses of material package enterprise.
Along with the development competition of material package industry is also more and more fierce, large multiple enterprises is all being pursued high production efficiency.The package speed that the electronic quantitative packing is weighed and the requirement of precision are more and more higher.Yet the mature technology of electronic quantitative packing scale has been applied for a long time, want in the situation that to guarantee that precision increases a little speed all very difficult.
Weigh two aspects that have of speed of impact, one is that (want to increase batching speed and just must sacrifice precision in actual application, this is common practise in the use of electronic quantitative packing scale for the batching speed of metering device (being commonly called as feeder).), one is weighing container steady speed after having joined material, weighing container can produce many-sided waving in the impact process fed intake, in the process of waving, sensor is connected and will produces displacement with weighing container, if connect more accurate, will produce and suppress the strength phenomenon, suppressing strength can be in the situation that the deadweight slow release of material, and in dispose procedure, batching controller just can not be stablized rated weight and causes entering next process and be discharged in material bag.
At present the connection mode of electronic quantitative packing scale LOAD CELLS and weighing container has a lot of forms, fixing, adjustable etc.These modes all can produce the defect of suppressing strength.For example: between the sensor module of adjustable form and weighing container, being connected is all with oscillating bearing (being commonly called as the flake joint), the oscillating bearing variable range is limited, and be that circular arc coordinates between middle bearing hub and bearing, between circular arc and circular arc, be that face contacts, friction force is larger, and the degree of flexibility between them directly defines the steady speed of weighing container.And the present invention adopts, being the cooperation of the face of cylinder to the face of cylinder, is the contact of point, almost there is no friction force, has thoroughly solved this problem.
Summary of the invention
The objective of the invention is in order to make up the deficiency of prior art, a kind of full degree of freedom suspension type electronic quantitative packing scale meausring apparatus is provided.
The present invention is achieved through the following technical solutions:
A kind of full degree of freedom suspension type electronic quantitative packing scale meausring apparatus, include weighing container, it is characterized in that: on three directions of described weighing container oral area, be respectively equipped with permanent seat, the identical triangular arranged that is of spacing between described permanent seat, on described permanent seat, sensor module is installed, described sensor module includes respectively sensor stand, on described sensor stand, LOAD CELLS is installed, the lower end of described sensor stand is equipped with regulating connecting rod, the bottom of described regulating connecting rod is equipped with cylindrical water chestnut suspension ring, described cylindrical water chestnut suspension ring are connected cooperation with the cylindrical pin of permanent seat outer end, the middle part of described cylindrical pin is provided with the kidney-shaped groove coordinated with cylindrical water chestnut suspension ring, be sent to controller after the output line of three LOAD CELLS is arranged side by side, get final product the heavy amount of general name of accurate Calculation weighing container.
Described regulating connecting rod includes upper and lower connecting thread bar, and between described upper and lower connecting thread bar, spiral has the adapter sleeve screwed with upper and lower connecting thread bar.
Its principle is: three directions in weighing container have been installed three sensor modules, this distributes and has not only met the requirement that load-bearing distributes, can guarantee the stability in weighing process simultaneously, make it on same level, sensor module is connected with the cylindrical pin on weighing container with cylinder water chestnut suspension ring by regulating connecting rod.When material flow in weighing container from top to bottom, the bottom that impacts weighing container causes the weighing container fitfull to rock, adopt the structure of cylinder water chestnut suspension ring and cylindrical pin, it between it, is the contact of point, friction force is minimum can or slightly be disregarded, flexible motion while making to rock between weighing container and sensor module, not there will be the possibility of suppressing strength, thereby indirectly guaranteed the particularity of weighing.
Advantage of the present invention is:
Between cylinder water chestnut suspension ring of the present invention and cylindrical pin, be to contact, friction force is minimum can or slightly be disregarded, flexible motion while making to rock between weighing container and sensor module, not there will be the possibility of suppressing strength, thereby indirectly guaranteed the particularity of weighing.
