Abstract
The utility model relates to the controlling device of a cement packing machine, which is in particular suitable for controlling the weighing and packaging of cements. The utility model has the technical proposal that an electric magnet is adopted to control a material unloading flashboard; after the bagging of the cement achieves the scheduled weight, a weighing sensing section passes signals into a control circuit, the control circuit drives the electric magnet to be attracted, the flashboard is closed, and material loading is ceased. Simultaneously, an automatic clear circuit is also arranged in the control circuit for enhancing the weighing precision. The utility model has the characteristics of high weighing precision, convenient use, etc., and is in particular suitable for rebuilding the existing packing machines.
Description
The utility model relates to a kind of control setup of wrapping machine, and it is specially adapted to control that cement is weighed, packed.
At present, generally the cement-packing plant of Cai Yonging all adopts the lever weighing, after the cement pack reaches constant weight, because leverage drives the blowing closing gate, finishes and once packs weighing work, because lever construction is easy to wear, precision is low, the out of reach state specified standards.Therefore, people attempt to adopt microcomputer to handle, but just are applied in management, the statistical work.Common weighing computer control device, because of not having perfect zero clearing link, weighing precision is low, uses inconvenience.
The utility model purpose provides a kind of control setup of cement-packing plant, makes weighing of its control cement packing, improves weighing precision, the convenient use.
The technical solution of the utility model is; Adopt electromagnet to handle the blowing flashboard, by control circuit control work of electromagnet.When cement pack weight reaches predetermined value, control circuit triggers electromagnetic actuation, closes the blowing flashboard, finish once weigh, packing work.
In order to improve weighing precision, in microprocessor control system, be provided with the zero clearing link, this link comprises D8748 micro controller system and DAC0832 D and A converter in forming, when system starts working, the D8748 micro controller system is in conjunction with the DAC0832 D and A converter, voltage signal is measured during to empty scale, and zero clearing, to improve survey precision.
The utility model is handled the blowing flashboard owing to adopt control circuit control electromagnetic actuation, and during to empty scale electric signal measure, zero clearing, have weighing precision height, long service life, characteristics such as easy to operate.Particularly suitable only needs change a little to the transformation of existing cement-packing plant, can reach goal of the invention.
Fig. 1 is the utility model embodiment 1 electromagnetic actuator structural representation.
Fig. 2 is the utility model embodiment 2 electromagnetic actuator structural representations.
Fig. 3 is the utility model control system block scheme.
Fig. 4 is the utility model control system schematic circuit diagram.
With reference to accompanying drawing, further specify the utility model by embodiment.
In the control system block scheme, handle through op amp (10) from LOAD CELLS amplified signal V, enter analysis comparator (11) and compare.Electric signal when if this signal is empty scale, automatic reset circuit (12) is started working, and system is carried out automatic clear, to guarantee weighing precision.Behind the beginning blowing, according to the signal after amplifying from LOAD CELLS, digital display circuit (13) shows pack weight at any time, when pack weight reaches predetermined value, send control signal P, through zero passage trigger circuit (14), trigger silicon control (15) conducting, electromagnet (16) adhesive, close the blowing flashboard, finish the process that once packs, simultaneously, bag number accumulative total circuit (17) record once.
In the control circuit principle, be two cement-packing plants of chewing, because of two groups of control circuits are identical, omit the set of circuits schematic diagram.From the electric signal of pulling force sensor (18) after ICL7650 and LM324 op amp amplify, weighing results shows by digital display circuit (13), if during empty scale, the zero clearing link is started working, and behind comparator LM1414, micro controller system D8748 and D and A converter DAC0832 system is carried out automatic clear.Weighing-up wave compares by LM319 with the weight signal of being scheduled to, and when reaching predetermined value, sends control signal and enters zero-cross triggering circuit CD4011, and, trigger the silicon control conducting through photoelectrical coupler, make electromagnetic actuation, close the blowing flashboard, stop blowing.Promote counters count pack quantity by time base circuit NE555.
Embodiment 1
Predetermined pack gravimetric value is 50kg, and control system is carried out automatic clear, weighed, when actual weight reaches 50kg, and control system drive magnetic (1) adhesive, switch hook (2) resets, and flashboard (3) cuts out by the elastic force of spring (4), and pack finishes.During blowing, manually move handle (9), open flashboard (3), switch hook (2) locking, beginning blowing.Because handle (9), flashboard (3), switch hook (2) have kept the structure of existing cement-packing plant substantially,, can on existing wrapping machine, implement the utility model so change slightly.
In order to simplify the cement-packing plant discharge mechanism, alleviate the labour intensity of moving handle, adopt electromagnet (5) direct pull flashboard (8).During blowing, manually move handle,, alleviated the labour intensity that handle is moved owing to there is not action of the spring.When the actual pack of cement weight reached predetermined value, control system drive magnetic (5) adhesive was closed by pulley (7) and backguy (6) pulling gate (8).Finish bagwork one time.
Because electromagnet direct pull blowing flashboard, the utility model can be simplified the discharge mechanism of cement-packing plant, the convenient use.
Claims (4)
1, a kind of cement-packing plant control setup with weighing and sensing link, control circuit, blowing actuating unit, it is characterized in that said actuating unit comprises electromagnet, blowing flashboard, handle in forming, during blowing, move handle, open flashboard, blowing begins, after reaching predetermined weight, the weighing and sensing link is imported signal into control circuit, the adhesive of control circuit drive magnetic, close flashboard, stop blowing.
2, the cement-packing plant control mechanism according to claim 1 is characterized in that having the clear circuit that comprises micro controller system D8748, D and A converter DAC0832 in the composition of control circuit.
3, according to claim 1 or 2 described cement-packing plant control setups, the moving iron core that consists of electromagnet (1) that it is characterized in that actuating unit blocks switch hook (2), flashboard (4) is in the blowing state, behind the electromagnetic actuation, switch hook (2) resets, because the effect of spring (3), flashboard (4) closure stops blowing.
4, according to claim 1 or 2 described cement-packing plant control setups, it is characterized in that said actuating unit consists of electromagnet (5) and is connected with flashboard (8) with backguy (6) by pulley (7), electromagnet (5) is when being in release position, flashboard (8) is opened, the beginning blowing, reach predetermined weight after, electromagnetic actuation, close by pulley (7) and backguy (6) pulling flashboard (8), stop blowing.
