Description
Technical field
The utility model belongs to the packing mechanical equipment field, relates to a kind of intermittent packaging machine and draws a bag paper feed driving system, is particularly useful for intermittent packaging machine.
Background technology
The batch (-type) device of full automatic packaging is a big main flow of world's wrapping machine industry; Compare with the continous way device of full automatic packaging; The characteristics that have that material package finished bag forming effect is good, physical construction are simple, the installation and maintenance cost is low, so be widely used, pharmaceutical industry particularly.It is that one of two nip rolls are drive rolls that the quality that intermittent packaging machine draws bag paper feed link operational effect direct relation material package finished bag to be shaped, tradition draw bag to walk paper structure, relies on coupled step motor drive; Another is a driven roll, relies on action of the spring, draws a bag paper feed pulling motion with the relative friction realization of drive roll.Based on this motion base reason, in drawing bag paper feed operational process, two nip rolls operation asynchrony phenomenon can appear; Simultaneously the elastic force of driven roll holddown spring size, cause the paper feed process to take off paper, skidding with many factors such as the size of drive roll relative friction forces, the stationarity of two nip rolls rotating operations; So draw bag paper feed drive mechanism to become the problem that present intermittent packaging machine draws bag paper feed process to need emphasis to solve; Also be to improve to draw a bag paper feed running precision, guarantee packed products bag quality critical.But noise was very big when the batch (-type) device of full automatic packaging caused the complete machine operation based on physical construction operating principle factor; Equally based on mechanical transmission structure restriction complete machine running velocity; And the complete machine package speed can only arrive 60 bags/min, and wrapping machine draws bag length to be 150mm to the maximum, and complete machine power is very big again.Many factors have suppressed the development of batch (-type) device of full automatic packaging.So at present domestic and international continous way wrapping machine technology mode is based on following several modes.
1. draw bag clutch, the braking mode of paper feed traction
1) groundwork:
The motion principle of this batch (-type) device of full automatic packaging mainly is made up of two parts:
1. draw bag traction element to accomplish through the timesharing action of electromagnetic braking and electromagnetic clutch.Promptly drawing under bag signal effect, electromagnetic clutch is opened, and realizes drawing the bag operation; Draw bag time to arrive, solenoid closure finishes to draw the bag operation.
The involution operation of 2. horizontal sealing, vertical envelope is to rely on the mechanical cam on the batch (-type) device of full automatic packaging to realize horizontal sealing, vertical envelope intermittent moment.Promptly main motor and draw under bag signal effect, mechanical cam drives horizontal sealing, vertical sealing mechanism is opened, and draws bag mechanism to carry out when the time comes and draws the bag operation; Draw bag to finish, and mechanical cam will make horizontal sealing, vertical sealing mechanism closed, so horizontal vertical involution is operated.
3. circulate with this, the batch (-type) device of full automatic packaging is accomplished the three elements motion of drawing bag, filling, involution automatically.
2) problem that exists:
1. electromagnetic braking, clutch-plate be hard ware, long-term immobilization, clutch friction operation cause braking, clutch-plate to skid easily, braking effect receives very big influence, finally causes drawing the long trueness error of bag bag very big.
2. electromagnetic braking, the temporal hysteresis of clutch action (generally being tens ms) have increased vertical envelope and have drawn a bag pull-in time, cause drawing bag speed to improve.
The involution operation of 3. horizontal sealing, vertical envelope drives process based on mechanical cam, can't guarantee the fast sealing of horizontal sealing, vertical envelope, so influenced the running velocity of complete machine.
4. horizontal sealing is all adopted the 110VAC series-fed with every road heating circuit of vertical envelope, and the static direct current resistance of these powering mode two heating rods must be consistent, otherwise in heat process, and the adding of two heating rods pined for power difference can make a rapid wear wherein.
2. draw bag step motor drive pattern of paper feed traction
The motion principle of this batch (-type) device of full automatic packaging is made up of two parts equally:
1) groundwork:
1. draw bag trailer coupling to adopt step motor drive.Promptly drawing under bag signal effect,, accomplishing and draw the bag operation accordingly according to bag bag long parameter that draws that is provided with.
The involution operation of 2. horizontal sealing, vertical envelope is 2. 3. identical with 1-
2) problem that exists:
1. draw bag trailer coupling to adopt a step motor drive, make the fixed length precision that draws bag to a certain extent and draw a bag speed aspect all to be greatly improved and improve.Mechanical factor based on the complete machine motion is being difficult to further raising aspect the speed;
2. to draw one of bag paper feed two nip rolls be drive roll to tradition, relies on coupled step motor drive, and another is a driven roll, relies on action of the spring, realizes drawing a bag paper feed pulling motion with the relative friction of drive roll.Based on this motion base reason, in drawing bag paper feed operational process, two nip rolls operation asynchrony phenomenon can appear; So the elastic force of driven roll holddown spring size, relevant with the size of drive roll relative friction forces simultaneously is factor such as the stationarity of two nip rolls rotating operations and cause the paper feed process to take off paper, skidding.
3. the critical component former that draws bag paper feed process all adopts at present and makes by hand, so conformability is poor, can't guarantee the packaging bag Forming Quality of batch manufacturing former.
4. the configuration of intermittent packaging machine master motor and corresponding mechanical governor thereof, the cost and the system that increase complete engine set installation move noise and system electrical wiring complexity.
5. horizontal sealing, the same mechanical cam that adopts of vertical involution operation of sealing drive, and its Mechanical Driven process needs the time equally, and this is crucial for the running velocity of raising complete machine; Problems such as horizontal vertical envelope type of heating of while await solving.
6. existing cutting agency (granulator-rotating disk rotary unloading; Pulvis machine-screw rod rotary unloading) the blanking process also needs the time, so the blanking process of this cutting agency also is to suppress the key factor of complete machine package speed, also is one of problem that awaits solving.
