Abstract

An automatically quantitative packaging machine for small grain bags without sewing machine and hot-press sealing is composed of two identical packaging machines, each being composed of weighing mechanism, feeding gate, controller, and bag hanging and releasing mechanism, and features small size, simple structure, reliable work, low cost, precise metering and high productivity. It is fully automatic except bag hanging.

Description

Automatic quantitative grain packer

The present invention belongs to a kind of wrapping machine, and this wrapping machine is used for cereal products such as flour, rice are carried out the automatic ration inner wrapping.

A kind of grain small packer is arranged now, it is that filling of screw rod volume measurement and plastic film bag making machine tool are combined, and under the control of microcomputer, finishes jointly grain is carried out automatic quantitative packing.In order to solve the dust electrostatic adherence at film surface, cause bag to seal the problem of difficulty, Chinese patent 93229657 is retrofitted in screw rod metering pack portion at the top of this kind wrapping machine.A kind of grain small packer is arranged again, and it is that material is filled in the plastic film packaging bag of finished product after the pressure sensitivity weighing, and then carries out manual hot-press sealed.In order to make the hot-press sealed automation, Chinese patent 95237984 is provided with the folder bag manipulator on lower bearing bracket.

Pack grain with plastic film packaging bag and not only can produce airtight and the seal quality problem, the more important thing is and cause serious environmental to pollute.According to " People's Republic of China's immobilized waste contaminated environment is prevented therapy " regulation, product should adopt easily to return to utilize and easily handle or digestible packing material in environment.

The cloth packaging bag that the object of the present invention is to provide a kind of usefulness to be sewed with hasp comes the wrapping machine of automatic quantitative packing grain.This packaging bag can nondestructively be used many times.

Wrapping machine of the present invention by about two identical package packing machinies form, every machinery is all hung the off line structure by lever scale measuring mechanism, bin gate and switching control mechanism, packaging bag and is formed.

The mechanism that describes this machine below in conjunction with accompanying drawing in detail forms and working process.

Prismatic frame (7) is as claiming the thing frame to hang on the force axle (1).By (7) (1) and fulcrum pivot, cutter holds (2), and rolling counterweight Cylinder (4) is formed Weighing mechanism.Spring (5) and adjustable bolt (10) are decision thickness charge ratio (or press on the arm of force or hang a spacing weight).3 rotating shafts are arranged on the prismatic frame (7).Be equipped with in the rotating shaft (9) and hang bag branch (11) and weight arm (8).Spin (12) is arranged (8).(9) (11) (8) (12) and postive stop baffle (13) composition is hung and is taken off bag mechanism.The gum cover (16) of rotating shaft (15) and outside is that the clamping sack is used.Rotating shaft (30) and pattern (31) strut the prismatic frame automatically to the fixed position when the lever beam rises.Driving lever (28), Xiamen driving lever (29), the rocking handle (27) of calling, following gate control fan plate (24), Xiamen fork (23), Xiamen pull bar (22), Xiamen rocking handle (19), following door-hinge (20), Xiamen balance weight body (21) are formed the bin gate switching mechanism jointly to the doorstep.

The working process of this machine is as follows: the grain that falls into three-way pipe (25) by deadweight.Be subjected to stopping of (26) to the doorstep, can only flow to left side pipeline (14) and fall into packaging bag.When the grain in the packaging bag reaches quantitative 85% the time, under the effect of spring (5), lever beam (3) cw deflection, driving lever (28) is stirred rocking handle (27) to the doorstep to the doorstep, and (26) are turned over to the left side.Because to the doorstep the centre of (26) has suitable small opening, fall in the packaging bag end of thick charging that Here it is, the beginning of thin charging so there is the grain of some will leakage current to go into left side pipe (14).When grain in the bag reaches quantitative, lever beam (3) will continue cw and compile commentaries on classics, (4) roll to the right, promoting Xiamen driving lever (29) moves right, by (24) (23) (22) are pulled to the right, left-hand door (17) is just shut like this, and left side bag charging finishes, right door is opened, and packaging bag thick charging in the right begins.When the prismatic frame sank, its lower end was drawn close to the centre, and finally sack two limit clampings, sack is shut by hasp.When the prismatic frame sank, (8) produced deflection, and under the stopping of (13), the spin (12) in (8) is rolled to the left side at last, (8) conter clockwise deflection automatically, (11) down, bag is with and is slipped down from (11), packaging bag falls.Because weightless, lever beam (3) inhour deflects into original position.The right package packing machine will begin the packaging process of left side package packing machine.

Compare with existing automatic quantitative packing machine, the advantage of automatic quantitative packing machine of the present invention is: machinery takes turns to operate 1,, and grain continues to flow, and package speed is fast, the output height.2, in fact charging has three phases, and what advance at first is that the material of the leakage material hoarded in the pipe and thick charging flows in the packaging bag together, is thick charging then, is thin charging at last.Packing speed is fast like this, the measuring accuracy height.If following gate control is changed into contact pointless electromagnetic switch control Xiamen fork (23), then package speed is faster, and measuring accuracy is higher.3, volume is little, and structure is extremely simple, and cost is extremely low.4, reliable operation, easy to maintenance.5, except that artificial extension bag, all the other whole automations of working alleviate working strength of workers greatly.6, do not need outer power.

Claims

1, a kind of grain automatic ration small packer comprises weighing part, bin gate and switching control section, and packaging bag is hung and is taken off part.It is characterized in that identical two package packing machinies are combined in this machine, shown in Figure of description, the title thing frame of every package packing machine is made two prismatic framves and is hung on the axle of force, be equipped with in the above and strut axle, hang and take off bag axle, clamping axle, extension takes off to be equipped with on the bag axle and is linked with branch and weight arm, be provided with to the doorstep two Xiamen in the feed pipe, have small opening in the middle of to the doorstep, divide into stage clip or on the arm of force, establish a stage clip or press a spacing weight at the weighing arm of lever beam.

2, wrapping machine according to claim 1, its extension take off in the band weight arm to be had a spin or mercury is housed.
