Description

Short-stroke bag opening and closing mechanism

Technical Field

The utility model relates to a equipment for packing field specifically is a sack mechanism that opens and shuts of short stroke.

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 packaging bag opening mechanism is used for opening 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.

When this patent is implemented, move the wrapping bag to bag clamping mechanism department through sending a bag mechanism, then bag clamping mechanism implements to the wrapping bag and gets, and after the filling was accomplished, bag clamping mechanism removed again and seals mechanism department and seal, and in the above-mentioned action, send a bag mechanism and bag clamping mechanism to realize through two sets of independent actuating mechanism, just so increased actuating mechanism's quantity, increased the stroke of wrapping bag simultaneously

SUMMERY OF THE UTILITY MODEL

The utility model aims at above problem, provide a sack of short stroke mechanism that opens and shuts, can reduce the stroke of wrapping bag.

For the purpose of realizing above, the technical scheme that this application adopted is a sack of short stroke mechanism that opens and shuts, and it includes the support, be provided with the clamping part on the support, and the clamping part uses support removal route to be relative setting mutually for the axle, is provided with out bag portion on support removal route, open bag portion including the relative bag portion of inhaling that sets up, the bag portion of inhaling of both sides carries out the adjustment of interval under the drive of opening bag actuating mechanism, inhale bag portion and clamping part non-syntropy setting.

Further, in order to improve the packaging quality, the materials loaded into the packaging bag are often loaded into the inner bag firstly, 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 a pushing device in the feeding unit and retreated, the inner bag can move forward for a certain distance due to the fact that the inner bag loses the limit of the pushing device, and the inner bag is likely to move to the sealing area of the packaging bag; the bag opening part comprises material locking parts which are oppositely arranged, the distance between the material locking parts on the two sides is adjustable, and materials filled into the packaging bag are pressed through the material locking parts, so that the materials are 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 phenomenon 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 dropping down when the packaging bag is filled, a material supporting plate is arranged at the far end of the bag opening 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, then the bag sucking parts on the two sides are mutually far away to open the bag opening of the packaging bag, and the distance between the clamping parts is reduced at the moment; 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 clamping parts drive the packaging bag to move to a subsequent station. Above-mentioned in-process replaces sending a bag mechanism to send the wrapping bag to the filling station through the clamping part, can reduce actuating mechanism's quantity, shortens the stroke simultaneously.
