Sub-clamp device for clamping M-shaped packaging bag

Abstract

The invention discloses a sub-clamp device for clamping an M-shaped packaging bag. The sub-clamp device comprises a left sub-clamp seat (6) and a right sub-clamp seat (5) which are provided with gearseats (7) correspondingly. An upper rack (8), a gear (9) and a lower rack (10) which are mutually connected are mounted on each gear seat. An outer clamp mechanism (30) is mounted on each upper rack,and an inner clamp mechanism (31) is mounted on each lower rack. The lower racks are connected with clamp opening push plates (1). The front edge and the rear edge of the left side and the right sideof the M-shaped packaging bag are clamped through the outer clamp mechanisms and the inner clamp mechanisms correspondingly, the whole outer clamp mechanisms and inner clamp mechanisms are opened outwards through the clamp opening push plates, and thus a bag opening of the M-shaped packaging bag is opened smoothly and completely; and the quantity of a package filled with materials is ensured, thepackaging environment is optimized, the material packaging quality is obviously improved, and the material packaging speed is obviously increased.

Description

technical field [0001] The invention relates to a packaging machine, in particular to a sub clip device. Background technique [0002] At present, packaging bags are generally divided into three-side sealing bags, four-side sealing bags, special-shaped bags, M-shaped packaging bags, etc., among which: the longitudinal sides of the M-shaped packaging bag are concave and M-shaped, and the mouth of the bag is generally It is a concave-convex groove fastening method, and it can be clamped and opened with a suction cup or a sub-clip when the package is in use. When using a suction cup, the packaging bag will fall off and cannot be opened due to the air supply or insufficient vacuuming. The two sides of the packaging bag can be clamped using ordinary sub-clamp components, but it is difficult to clamp the front and rear edges of the concave sides. Insufficient opening of the bag opening will result in waste of materials, insufficient packaging volume, environmental pollution, etc....

Problems solved by technology

When using a suction cup, the packaging bag will fall off and cannot be opened due to the air supply or insufficient vacuuming. The two sides of the packaging bag can be clamped using ordinary sub-clamp components, but it is difficult to clamp the front and rear edges of the concave sides. Insufficient opening of the bag opening will result in waste of materials, insufficient packaging volume, environmental pollution, etc., which will adversely affect packaging filling, packaging speed and quality
