Description

Longitudinal bag opening and sealing mechanism

Technical Field

The utility model relates to a equipment for packing field specifically is a vertically open a bag envelope mechanism.

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.

In the actions, the path of the packaging bag moving to the filling station and the path of the packaging bag moving to the sealing station are not on the same line, so that certain limitation is generated on the arrangement of a production line, and particularly, a large field area is required, and the requirement on diversified production line arrangement cannot be met.

SUMMERY OF THE UTILITY MODEL

The utility model aims at above problem, provide a vertically open a bag envelope mechanism for the wrapping bag is on an online with the wrapping bag to the route that seals the station removal to the route that the filling station removed.

For realizing above mesh, the technical scheme that this application adopted is a vertically open a bag envelope mechanism, and it includes the support, the support is provided with the clamping part relatively, is provided with out a bag envelope portion on support moving path, it includes opening the bag group and envelope group along what support moving direction interval set up to open a bag envelope portion, it inhales opening a bag actuating mechanism of bag portion relative movement including inhaling bag portion and drive that relative setting was inhaled including opening a bag group, envelope group is including the envelope portion and the envelope actuating mechanism of drive envelope portion relative movement that relative setting was inhaled, the moving direction of inhaling bag portion, envelope portion, clamping part is different with support moving direction, the moving direction of inhaling bag portion and envelope portion is the same but different with the moving direction of clamping part.

Further, in order to improve the packaging quality, materials loaded into the packaging bag are often loaded into the inner bag firstly, the inner bag is often made of plastic bags or other flexible materials, and after the inner bag is pushed into the outer packaging bag and retreated by a pushing device in the feeding unit, the inner bag moves forwards 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 packaging bag; therefore, the bag opening and sealing part is internally provided with material locking parts which are oppositely arranged, the distance between the material locking parts at two sides is adjustable, and the material filled into the packaging bag is pressed through the material locking parts to be prevented from moving to the sealing area of the packaging bag.

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 arranged to be an inclined surface facing the bottom of the packaging bag.

Furthermore, in order to straighten the bag opening, a clamping driving mechanism for driving the clamping part is arranged on the support.

Furthermore, in order to make the sack at the in-process of flare-outing, the position of sack can not change, avoids the department of sealing of wrapping bag phenomenons such as bending to appear, 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, pass through spring coupling between extension and the sliding seat.

Furthermore, in order to avoid the bag tail falling down when the packaging bag is filled, a material supporting plate is arranged at the far end of the bag opening and sealing part on the support.

Further, after the sealing is finished, the packaging bag needs to be put down, and in order to automatically separate the packaging bag from the material supporting plate, the material supporting plate is connected with the material supporting driving mechanism.

The beneficial effect of this application: the clamping parts fix two side edges of the packaging bag and drive the packaging bag to move between the bag sucking parts, the bag sucking parts move oppositely to suck the front and back surfaces of the packaging bag, after the packaging bag and the bag sucking parts are connected, the bag sucking parts on the two sides are far away from each other to open the opening of the packaging bag, and at the moment, the distance between the clamping parts is reduced; after the materials are filled, the clamping parts are far away from each other so as to straighten the bag opening and separate the packaging bag from the bag suction part, and then the bag sealing part moves oppositely so as to seal the packaging bag. In the process, the path of the packaging bag moving to the filling station and the path of the packaging bag moving to the sealing station are on the same line, a novel production line arrangement mode is provided, and the packaging bag sealing device can adapt to narrow production places.
