Description

The valve port bag package machine

The utility model relates to a kind of package packing machine, particularly a kind of valve port bag package machine, and valve port bag packing is mainly used in grain, feed, the packing of materials such as chemical industry.The valve port bag is as a kind of novel package container, and its feature is that packaging process does not have dust; Exempt to seal; For moulding, reduce environmental pollution with paper.

External valve port bag package machine has two types at present: a class is a Purely mechanical, the metering section of this wrapping machine is a beam scale, set up the extreme higher position of arm beam of steelyard perk in advance according to packing specification, and on this position, load onto a micro-switch, in the reinforced process, the arm beam of steelyard slowly lifts, and is little during to switch when running into, the micro-switch action makes reinforced motor stall, and expression is reinforced to be finished.This machine pack and bleed are manual operation, and it is simple in structure, and cost is low.But because in the reinforced process, the charge pipe of suit packaging bag contacts with frame, thereby has limited the precision of complete machine.Change packing specification if desired, not only need to reset the position of micro-switch, and for guaranteeing that precision also needs the edge of a knife of steelyard is done regularly finishing.The bagging and the bleed of another kind of valve port bag package machine are finished by manipulator, each action of weighing and metering is automatic guidance, but this wrapping machine system complex, and cost costliness and its mode of operation are to weigh earlier afterwards to pack, promptly weigh and pack and can not carry out simultaneously, work efficiency is lower.

The purpose of this utility model is a kind of valve port bag package machine of developing at above deficiency, and it has soon, feeds in raw material slowly; High-precision electronic scale real time measure also shows; Vibrating mechanism guarantees that packaging bag tamps; Reinforced snap catch; The power-assisted bleed; The material level automatic guidance, overproof warning; Functions such as automatic round-off error, counting, automatic peeling.Of the present utility model reinforced carry out simultaneously with weighing can be saved the packing time; Adopt that the Single-chip Controlling motor carries out slightly, finishing material and bag pushing mechanism, make this machine work more reliable; Magnet stopper is adopted in braking, to guarantee charging precision.

The utility model is achieved in that the valve port bag package machine comprises weigh control instrument 1 and the motor 10 that is installed in frame 14 bottoms that is installed in frame 14 tops, wherein an end of sensor 3 is fixed on the frame 14, the other end and bearing tube 5 are for being rigidly connected, one end of screw shell 6 is fixed on the top of frame 14 by screw-clamps 15, the other end contactlessly is installed in the bearing tube 5, reinforced spiral 7 by bearing installation on screw-clamps 15 and be threaded onto in the screw shell 6, inlet point on the feed opening of storage bin hopper 2 and the screw shell 6 is by bolted connection, folder bag mechanism 4 is installed on the link span of sensor 3 and bearing tube 5, bleed mechanism 8 is installed in the left side of frame 14, vibrating mechanism 9 be placed on bearing tube 5 under, the armature of magnet stopper 11 is installed in the end of the output shaft of motor 10, and the coil stationary of magnet stopper 11 is on frame 14.

The utility model can be achieved in that also sensor 3 is the beam type LOAD CELLS.

Good effect of the present utility model is:

1, this machine is imported by keyboard, the specification of can in the weighing allowed band, changing package arbitrarily easily, and this is the prime advantage that compares to the Purely mechanical wrapping machine.

2, the utility model precision height, its full accuracy can reach 0.05%.

3, packing of the present utility model and weigh and can carry out simultaneously, and adopt double speed reinforced, the several times of increasing work efficiency.

4, this machine adopts not only good reliability of Single-chip Controlling, and weighing system is hermetic type, makes the utility model have very strong adaptive capacity to bad working environment.

The utility model is described in further detail below in conjunction with accompanying drawing.

Shown in Fig. 1,2,3,4,5.At first the weight of packing specification is input in the singlechip CPU of the control instrument 1 of weighing (promptly setting) by keyboard 17, then with the valve port bag for packing fruits on bearing tube 5, by folder bag mechanism 4 the valve port bag is clamped on the bearing tube 5, press reinforced button 18, send reinforced signal, the relay J 1 of control motor 10 and control vibrating mechanism 9, J2 work, connect motor 10 and drive reinforced spiral 7 rapid loadings, cylinder 16 promotes vibrating mechanism 9 risings simultaneously, make it to contact valve port packaging bag bottom, and generation vibration, the material that adds in the packaging bag is tamped, after vibration a period of time, relay J 2 outages of control vibrating mechanism 9, vibrating mechanism 9 failure of oscillations are also regained cylinder 16, break away from packaging bag.When be dosed to setting weight 90-95% the time, the relay J 3 of the fast conversion at a slow speed of control motor and the relay J 4 charged actions of control magnet stopper 11 make motor 10 by high-speed transitions to low speed rotation, magnet stopper 11 work simultaneously, make motor 10 in the extremely short time by after being stabilized to slow running at a high speed, relay J 4 outages of control magnet stopper 11, magnet stopper 11 quits work.When being dosed to setting weight, magnet stopper 11 moves once more, relay J 1, J3 outage, and reinforced spiral 7 is braked, and finishes reinforced.Then after weighing 1 pair of control instrument overproof differentiation and error correction having been carried out in the packaging bag of filling, relay J 5 work of the relay J 2 of control vibrating mechanism 9 and control bleed mechanism 8, cylinder 16 is risen, hold at the bottom of the valve port packaging bag bag, make 8 actions of bleed mechanism simultaneously, the valve port packaging bag is extrapolated from the bearing tube 5, finish a packaging process.When storage bin hopper 2 lacks material, relay J 6 work of control feed mechanism 13, make feed mechanism 13 feeding in storage bin hopper 2, when material level detector switch 12 predicts material in the storage bin hopper 2 and is added to certain position, relay J 6 outages, feed mechanism 13 stops feeding in storage bin hopper 2, thereby realizes the material level automatic guidance.One end of sensor 3 is fixed on the frame 14, the other end and bearing tube 5 are for being rigidly connected, singlechip CPU analyzes to weighing-up wave and the setting weight value from LOAD CELLS 3, by data bus output control signal corresponding, through latches, drive relay J 1, J2, J3, J4, J5, J6 work, each action in the control cock pocket packaging process.
