Description

Packaging bag opening device of packaging machine

Technical Field

The invention belongs to the technical field of packaging, and relates to a packaging device, in particular to a packaging bag opening device of a packaging machine.

Background

With the development of packaging technology, most packaging devices are completed in an automated manner. The packaging machine can be applied to packaging of cylindrical products such as cups, paper bowls and the like. At present, disposable cups are widely applied to various occasions, the production scale of the cups is larger and larger, and the production, stacking and packaging of the cups are completed by adopting an automatic production line. At present, the main steps of automatic packaging of cups in the prior art are firstly to unfold a plastic mold, the plastic mold presents a tubular structure with an unencapsulated side surface after passing through a bending sheet, a cup with a completed stack is moved onto the bent plastic mold through a conveying mechanism, the plastic mold drives the cup to move, the unencapsulated side surface is encapsulated through a pulley heat sealing machine when the plastic mold moves, and the plastic mold moves to a strip-shaped heat sealing machine after the side surface heat sealing is completed to heat-seal the end surface of the tubular plastic mold.

The plastic mold forms a cylindrical structure with the side surface closed by the heat sealing of the pulley heat sealing machine in the unfolding state in the structure, and the cup is thin and long in side sealing length in the packaging mode, so that the plastic mold is easy to break in the heat sealing position of the side surface in the practical process. Therefore, people can easily think that the cup is packaged by adopting an integrally formed packaging bag (only the end part of the packaging bag is provided with an opening), the integrally formed packaging bag is not easy to crack and has good packaging effect, the opening of the packaging bag and the bag body are in a closed state, and the opening of the packaging bag and the bag body need to be opened. The technical personnel in the field can think that prop the sack through manual mode and put into the wrapping bag again, above-mentioned distraction device can only prop the sack and open, and inconvenient realization wrapping bag body struts, and the cup still is difficult to pack.

Disclosure of Invention

The invention provides a packaging bag opening device of a packaging machine, aiming at the problems in the prior art, and the packaging bag opening device can keep the opening and the bag body in a continuously opened state when packaging bags are packaged.

The invention is realized by the following technical scheme: the utility model provides a wrapping bag distraction device of packagine machine, its characterized in that includes the fixing base and installs the slide on the fixing base, there is the slider that can place at the wrapping bag inside on the slide, slider first position and second position reciprocating sliding on the slide, the wrapping bag is distracted when the slider slides to the second position from first position, and manipulator centre gripping wrapping bag just makes the wrapping bag keep the state of strutting.

In this scheme, closed wrapping bag is placed on the slide, the sack of wrapping bag is in the primary importance of slide, adopt the manipulator to strut the wrapping bag sack, the slider is placed in the wrapping bag and is in the primary importance of slide, when the slider slides to the second place from the primary importance on the slide, strut the sack of wrapping bag and the wrapping bag body that is located primary importance and second place, the manipulator centre gripping is at the sack of wrapping bag and make the wrapping bag keep the state of strutting, when the wrapping bag is in the state of strutting, make the cup of stack get into in the wrapping bag, improve the efficiency of packing and wrapping bag integrated into one piece be difficult to the breakage. Through the structure, the bag opening and the bag body of the packaging bag can be automatically opened and kept in the opening state, and the bag opening efficiency is improved.

In the packaging bag opening device of the packaging machine, the sliding plate is hinged to the fixed seat, and the sliding plate rotates and can be inclined. The slide articulates on the fixing base, and power unit can drive the slide and rotate the slope on the fixing base, and the slider on the slide reciprocates at primary importance and second place and slides under the action of gravity for the wrapping bag can strut and keep the state of strutting.

In the packaging bag opening device of the packaging machine, permanent magnet strips are arranged in the sliding block, electromagnets used for attracting the sliding block are arranged at the first position and the second position of the sliding plate, and the electromagnets are opposite to the permanent magnet strips in magnetism. When the sliding block needs to slide away from the first position, the electromagnet is powered off, and the sliding block slides away from the first position under the action of gravity along with the rotation of the sliding plate; the slider moves in the same manner in the second position as in the first position.

In the above-mentioned packing bag opening device of the packing machine, the slider reaches the first position or the second position of the slide plate, and the slide plate is rotated from the current inclined state to be inclined in the reverse direction. The slide plate is reversely inclined to enable the slide block not to slide and keep balance after reaching the first position or the second position, the slide block is prevented from being separated from the track, and when the slide block needs to leave the first position or the second position, the current inclination angle of the slide plate is increased to enable the slide block to slide.

In foretell packagine machine's wrapping bag strutting arrangement, install the permanent magnetism strip in the slider, install the electro-magnet on the slide, the electro-magnet drives the slider at the first position and the reciprocating sliding of second position of slide.

In the above-mentioned wrapping bag of packagine machine struts device, the electro-magnet is established in the both sides of slide. Electromagnets are arranged on two sides of the sliding plate and drive the sliding block to slide on the sliding plate.

In the above packaging bag opening device of the packaging machine, the electromagnet is provided at the bottom of the slide plate. The electromagnet is arranged at the bottom of the sliding block and has the same magnetism as the permanent magnet in the sliding block, the electromagnets are arranged at the front end and the rear end of the sliding block in the moving direction in a rolling mode, and the electromagnet can push the sliding block to move after offsetting part of the gravity of the sliding block.

In foretell packagine machine's wrapping bag strutting arrangement, the slider adopts plastics to make, the slider is the cylindricality, and the guide way has been seted up to the front end of slider orientation first position, and the tip of slider orientation second position is equipped with the arc angle. The slider is the cylindricality, and the appearance is similar with the cup of stack, is favorable to the packing of cup, and the guide way has been seted up to the front end of slider, and the setting of guide way is favorable to manipulator entering guide way when first position, plays clamping action to the sack of wrapping bag, and the arc angle plays certain guard action to the wrapping bag when sliding.

Compared with the prior art, this packagine machine's wrapping bag distraction device has following advantage:

1. in this scheme, the slider is located the wrapping bag inside, and wrapping bag sack and the bag body can strut automatically and keep the state of strutting, has improved the efficiency of opening the bag.

2. This scheme wrapping bag integrated into one piece is difficult to the breakage when cup packing or after packing.
