Description

Vertical bag opening and sealing structure

Technical Field

The utility model relates to a equipment for packing field specifically is a vertical bag structure of opening envelope.

Background

The bagging is a common bagging method, and the process is to open the packaging bag, then fill the material into the packaging bag, and then straighten the bag opening of the packaging bag to perform subsequent operations such as sealing. In the process, if manual work is adopted, a large amount of manpower is consumed, the production efficiency is difficult to improve, and poor packaging is easy to occur. Therefore, in the prior art, automatic equipment is mostly adopted to complete bagging. For example, in patent publication No. CN206437238U, a filling and sealing apparatus with a photoelectric intelligent robot is disclosed. The material moves to the material pushing device along with the material conveying device which is transversely arranged, the bag clamping mechanism moves the packaging bag to the bag opening mechanism, the bag opening mechanism opens the packaging bag, the packaging bag is in a flat state at the moment, the opened bag opening faces the material pushing device, and the material pushing device pushes the material into the packaging bag; then the bag clamping mechanism clamps the packaging bag and transversely moves the packaging bag to the sealing mechanism for sealing.

Among the above-mentioned action, regardless of the removal of material, still the removal of filling completion back wrapping bag all is horizontal, just so requires to have great place to satisfy the stroke requirement of each part, and when the production place is less, will appear being difficult to the winding displacement or winding displacement quantity can't satisfy the requirement. And the packaging bags need to be kept in a horizontal state in the moving, filling and other processes, so that the packaging bags cannot be adapted to a vertical filling production line.

SUMMERY OF THE UTILITY MODEL

The utility model aims at above problem, provide a vertical bag structure of opening envelope, can adapt to vertical filling.

In order to achieve the purpose, the technical scheme adopted by the utility model is a vertical bag opening and sealing structure, which comprises bag opening and sealing groups which are oppositely arranged along the transverse direction, wherein the bag opening and sealing groups are arranged on the front side and the back side of a packaging bag, each bag opening and sealing group comprises a bag suction part and a bag sealing part which are arranged along the vertical direction at intervals, the distance between the bag suction parts at the two sides and the bag sealing parts at the two sides is adjustable, the side edge of the packaging bag is provided with a clamping part which is arranged on a support, the support moves along the vertical direction, and the distance between the clamping parts at the two sides is adjustable; when inhaling bag portion and pulling open the sack, the clamping part removes to the wrapping bag inboard, makes the sack of wrapping bag open up to can adapt to vertical filling, along with keeping away from each other of clamping part, can straighten the sack, make the wrapping bag with inhale bag portion separation, process such as convenient subsequent sealing.

Further, in order to complete bag opening and bag sealing, the bag suction part is connected with a bag suction driving mechanism, and the bag sealing part is connected with a bag sealing driving mechanism.

Furthermore, in order to ensure that the bag mouth is straightened, the height of the bag mouth cannot be changed, the phenomena of bending and the like of the packaging bag are avoided, and the support is provided with a transverse driving mechanism for driving the clamping parts at two sides to be away from each other.

Further, for the stability that promotes the clamping part and remove, be provided with the guide rail on the support, be provided with the sliding seat on the guide rail, the clamping part sets up on the sliding seat.

Further, because the sack of wrapping bag opens along with inhaling bag portion, for the opening degree that ensures that the position of clamping part can just in time adapt to the wrapping bag, reduce the adjustment degree of difficulty, be provided with the extension on the support, be connected through the telescoping device between extension and the sliding seat, the telescoping device sets up with horizontal actuating mechanism syntropy.

Further, in order to improve the packaging quality, the materials loaded into the packaging bag are often loaded into the inner bag first, the inner bag is often made of a plastic bag or other flexible materials, and after the inner bag is pushed into the outer packaging bag by the pushing device and retreats, the inner bag moves forward for a certain distance due to the fact that the inner bag loses the limit of the pushing device, and therefore the inner bag is likely to move to the sealing area of the outer packaging bag. The bag opening and sealing set further comprises a material locking portion, and the material locking portion moves transversely under the driving of the material locking driving mechanism.

Furthermore, in order to push the inner bag or other materials to the bottom of the packaging bag and ensure that the materials cannot move to the sealing position of the packaging bag, the contact surface of the material locking part and the packaging bag is an inclined surface extending from bottom to top to one side of the packaging bag.

The utility model has the advantages that: the clamping parts fix two side edges of the packaging bag, the packaging bag is positioned between the bag sucking parts, the bag sucking parts move oppositely to suck the packaging bag, and then the opposite bag sucking parts are mutually far away to open the mouth of the packaging bag; after accomplishing the bagging-off, the clamping part is kept away from each other to straighten the sack and make the wrapping bag with inhale the separation of bag portion, then the clamping part moves along vertical direction, makes the line of sealing of wrapping bag remove between the envelope portion, and the envelope portion phase to phase movement when both sides is in order to accomplish with the wrapping bag contact and seal, and above-mentioned in-process wrapping bag is in erects the state of putting, can adapt to vertical filling.
