Production facilities with on-line weighing mechanism
Technical field
The utility model is a kind of novel production device, realizes the equipment improvement of weighing of material on-line continuous and conveying specifically.
Background technology
The computing machine of application of advanced and information-handling technique, the operating efficiency by improving equipment and the degree of automation of operating procedure improve production automation level become may and development tendency, but the equipment that is used for the Quantity production scene at present awaits further to improve and is perfect.
As existing powder or other non-standard external form raw materials, need carry out weighing and conveying by different technical recipes by manufacturing technique requirent.For the mixed material production scene of using the different materials prescription, because the disengaging each other of travel line and weighing mechanism, thereby production facilities only has conveying function and lacks the on-line weighing function, or only have the on-line weighing function and do not have conveying function, the two can't carry out organic combination, not only can't realize consecutive weighings conveying continuously simultaneously, nor possess the material of getting redundancy feature, therefore production efficiency is comparatively low, also has certain degree of difficulty in integrated artistic control.
The utility model content
Production facilities with on-line weighing mechanism described in the utility model, its purpose are to realize online, the consecutive weighings and the conveying of powder or other non-standard external form raw materials, thereby improve weighing precision and production efficiency.
Described production facilities with on-line weighing mechanism is that a consecutive weighings is carried manufacturing line, and it includes the identical weighing feedway of many group structures and is in series.
Described feedway head and the tail to each other connects, thereby the supporting material is being transmitted on the feedway and between feedway successively.Design point of the present utility model is, on described feedway, is furnished with weighing unit, and under the effect of detecting device and jacking system, realize on-line weighing, and can organize the weighing that realize different material, different formulations on the feedways simultaneously more, to improve the operating efficiency and the weighing precision of integral production equipment.
Described feedway mainly has, one transfer gantry of support fixation by being connected ground base;
Each transfer gantry rectangular shaped rim on forward and backward two ends, be respectively arranged with two groups of driving chain wheels;
Be set in one group of chain between the driving chain wheel along throughput direction;
And, by the reductor of its driving chain and one group of driving chain wheel realization socket.
Feedway with above-mentioned basic structure by the driving chain wheel and the chain of transfer gantry support fixation, can realize that material is carried successively.Wherein, reductor is a power input device, by the output shaft of reductor, the rotation that driving chain drives driving chain wheel, realizes controlling the motion of chain and stopping.
On the transfer gantry of described feedway, also be provided with a jacking system.Described jacking system has a lifting support, lift cylinder and many assembly guidances.Wherein,
Described lift cylinder is fixedly connected on the transfer gantry;
Its lifting support then realizes and being connected of transfer gantry by many assembly guidances, and when lift cylinder promoted the dipping and heaving of lifting support about doing, guide piece can guarantee the stationarity of lifting support.
Interior volume at described lifting support is provided with an electronic platform scale, and when lifting support rose, the feedway on the lifting support held up the charging basket that fills material and moves to next station; When lifting support fell, the charging basket that fills material broke away from feedway, drops on the electronic platform scale, carries out the weighing of material, realizes weighing and signal output.
As mentioned above, major advantage of the present utility model and beneficial effect are:
1, the production facilities that is in series by many groups feedway can be realized the on-line weighing of various materials and conveying continuously, and the weighing structure of material comes into plain view and can enhance productivity greatly.
2, can realize various materials or multiple product the prescription mixing production and unaffected each other.
3, after jacking system descended, charging basket broke away from feedway, directly contacts with electronic platform scale, has reduced because of feedway drops on the tare weight that increases on the electronic platform scale, thereby has improved weighing precision.
Description of drawings
Fig. 1 is described structural representation with production facilities of on-line weighing mechanism;
Fig. 2 is the construction profile scheme drawing of described feedway.
Fig. 3 is the schematic top plan view of Fig. 2.
Include feedway 1, electronic platform scale 3, detecting element 4 and charging basket 5 as shown in the figure.Base 11, lifting transfer gantry 12, driving chain wheel 13, chain 14, driving chain 15 and reductor 16;
Electronic platform scale support 21, lift cylinder 22 and guide piece 23.
The specific embodiment
Embodiment 1, and as shown in Figure 1 to Figure 3, described production facilities with on-line weighing mechanism has the mutual series connected feedway 1 of many groups.
Described feedway 1, its base 11 is connected and fixed on the ground and guarantees the guiding of lifting transfer gantry 12.Front and back ends at lifting transfer gantry 12 frames is respectively arranged with two groups of driving chain wheels 13.Between driving chain wheel 13, be arranged with two groups of chains 14.The output shaft of reductor 16 is connected with one group of driving chain wheel 13 by driving chain 15.
Described jacking system is made up of lifting transfer gantry 12, lift cylinder 22, two assembly guidances 23.
Above electronic platform scale support 21, be provided with an electronic platform scale 3.
Described series connected many group feedways 1 are arranged in a line, and the chain height of each feedway 1 is identical, and when the charging basket 5 that fills material was transferred on chain, jacking system rose, and electronic platform scale 3 is in the below of chain 14.
When needs carried out material weighing on certain feedway 1, detecting element 4 received control signal and feeds back to reductor 16, and ended the operation of driving chain wheel 13 under the control of reductor 16, and this moment, chain 14 also stopped to carry.Described lifting transfer gantry 12 is under the driving of lift cylinder 22, and chain 14 descends and breaks away from charging basket 5, falls on the platform balance 3 until charging basket 5.
After weighing finished, jacking system rose again, and then chain 14 holds up charging basket 5 and operation once more, and charging basket is continued to be fed forward.
