Description

Roller type carrier band make-up machine with cam structure

Technical field

The utility model relates to a kind of roller type carrier band make-up machine with cam structure.

Background technology

In the packed and transported process, all need to adopt the packing of antistatic material at electronic devices and components nowadays, thereby the carrier band of packing electronics finished product has just arisen at the historic moment.Commonly used PS, PC, antistatic materials such as A-PET, ABS are made into winding that width the differs raw material as carrier band as required.This winding is becoming the carrier band that can encapsulate the IC electronic product by just making heat, utilize vacuum adsorption molding, punching in mould after.

Nowadays domestic carrier band make-up machine major part is to adopt flat carrier band forming technique, its principle is exactly that stretching motion by cylinder drives winding and moves forward, by the raw material of motor rotation supply winding, realize the rewinding of product at the blowing place by the rotation of motor in rewinding place.At moulding section, heating is carried out in winding allowed raw material are softening to be utilized the ductility of its material self to allow its stretcher strain be full of mold cavity by vacuum suction to realize the carrier band moulding.After this section moulding was finished, after mobile cylinder drive forming winding moved apart shaping mould, it is continuously shaped that back segment continues to replenish realization.The carrier band of forming is again by the realization punching that moves up and down of follow-up stamping cylinder, just needs and will finish all technologies by cutting knife roll extrusion cutting greater than the edge of our required finished size after moulding and punching are finished.Yet there is following defective in flat carrier band forming technique:

1) flat moulding is Duan Mo, it or not progressive die moulding, motion is not stop to stretch to realize moving by cylinder to reach continuously shaped, in each moulding moving process, will produce error unavoidably like this, grown the quality that later accumulated error value will have influence on product when the time, produced high scrappage and cause waste.

2) vacuum suction in flat-plate molded is just in time to open when moulding, is unfavorable for moulding like this.

3) the carrier band punching of flat moulding is that cylinder or motor are finished, but carrier band move forward with moulding be the same also be by cylinder moving, so also be the cumulative departure that must cause the position, hole.

4) design of the mechanism structure of classic flat-plate formula causes production capacity low, speed slow (80-200mm/ hour).

Summary of the invention

The utility model purpose is: a kind of roller type carrier band make-up machine with cam structure is provided.

The technical solution of the utility model is: a kind of roller type carrier band make-up machine with cam structure, it comprises forming module and punching module at least, and described punching module comprises the punching pedestal, be installed in the two stands of the space on the punching pedestal, be installed in power transmission shaft between the two stands, be installed in first, second cam on the power transmission shaft, the arms swing part that swings up and down, the drift swing arm that an end matches and moves up and down with second cam match with first cam.

On above-mentioned technical scheme basis, further comprise attached technical scheme:

It further comprises the 3rd cam, an end match the left and right sides rocking arm that swings, move arm and be parallel to each other and allow carrier band to pass through with the transmission shafts direction with the carrier band of left and right sides synchronous rocker motion with the 3rd cam track, and wherein to move arm be disjunctor for arms swing part and carrier band.

The other end of described drift swing arm is held by the spring at least one vertical direction, and the other end of left and right sides rocking arm is held by at least one spring in a lateral direction.

The direction of principal axis of described arms swing part, drift swing arm, left and right sides rocking arm bearing of trend and power transmission shaft is perpendicular.

Described forming module, it comprises the fixed mount, upper cover body, the main body with several vacuum suction mouths, the lower cover that are positioned at a side and are used for fixing motor, be installed in shaping mould on the main body, be wrapped in carrier band on the shaping mould, be used for fixing shaping mould the shaping mould holder, drive the rotation of shaping mould holder and be located at driving pulley on the fixed mount, the vacuum slot that is connected with the vacuum suction mouth.

The utility model advantage is:

1) adopts the rotation round motion, can guarantee the continuity of moulding rather than intermittent and the speed of service is even, numerous before this flat carrier band formers have fundamentally been solved in forming process, because shifting formwork and the accumulated size error that produces causes the cavity dimension of carrier band inaccurate repeatedly.

2), allow vacuum be in opening always and can not influence strip motion by rotation and continual motion.

3) at the uniform velocity uninterruptedly moving of carrier band guarantees the temperature in moulding and the stable and uniform of vacuum suction, improves molding effect; And flat former in the past is in forming process, and carrier band is that discontinuous moves, so heating and vacuum all can not keep constant and cause molding effect undesirable.

4) punching module is to control separately under the prerequisite of a whole set of technological works such as moulding, and it is to adopt same motor to realize that by stable mechanical linkage the punching of coordinating moves ahead.

5) improved speed of production (180-300mm/ hour).
