Technical field

The utility model relates to the upright bag forming machine structure of a kind of square broken line, is generally used on the packaging facilities.

Background technology

In the prior art, upright bag forming machine structure generally comprises the sheet film forming tube, be used for sheet film is configured as tubular form, and the inner passage of this forming tube can import inserts; Seal tool rest in one, be used for tubular form is sealed in the butt joint of the both sides of the edge of sheet film; Two knuckle sheets are used to form upright bag two ends shape; End envelope tool rest is used for sealing-in is carried out at upright bag two ends that are shaped.This vertical packaging bag can be showed with the state display that supports in the shop, so this vertical packaging bag is widely used for replacing the packaged form of plastic box, bottle, jar recently.

Summary of the invention

The purpose of this utility model provides a kind of upright bag forming machine structure that can form cubic broken line in packaging bag.

The technical scheme of utility model is: a kind of square broken line founds the bag forming machine structure, comprise support, be fixedly installed on the square forming tube on the described support, middle envelope tool rest along described square forming tube length direction setting, be positioned at the first knuckle sheet of described square forming tube front side, be positioned at the second knuckle sheet of the described first knuckle sheet front side, end envelope tool rest between the described first knuckle sheet and the second knuckle sheet, the two edges of wherein one group of relative wall of described square forming tube stretch out along its width and form four chimbs, the junction of adjacent two walls of described square forming tube has pushed against roller respectively, described each its circumferencial direction of roller upper edge offers annular groove, and described each chimb is clamped in the corresponding annular groove.

Described square forming tube is provided with clamp clip at the rear side that is arranged in described envelope tool rest, and the length direction that described clamp clip prolongs described square forming tube extends.

The rear side of described square forming tube also is provided with the upright bag former of collar shape, and the center line of described upright bag former and the axial line of described square forming tube coincide, and described clamp clip is positioned at the bottom of described upright bag former.

Compressed contact roller respectively at least one group of relative outside wall surface in the described square forming tube.

The described first knuckle sheet is a rectangle knuckle sheet and along the length direction setting of described square forming tube, and the described second knuckle sheet is a triangle knuckle sheet and along the width setting of square forming tube.

Compared with the prior art the utility model has following advantage: the two edges of one group of relative face of described square forming tube stretch out along its width and form four chimbs, and on four angles of square forming tube, pushed against roller respectively, its circumferencial direction of roller upper edge offers annular groove, each chimb is clamped in the corresponding annular groove, be arranged so that four bights of formation like this by the packaging bag nature of forming tube, and stay broken line at this, used mechanism structure is simpler, and the folding line that stays also compares nature, utilize two knuckle sheets that the establishment shape is done in packaging bag, make profile more attractive in appearance, it can be erected when being placed on the thing frame, bandwagon effect is better.

Wherein: 1, support 2, square forming tube; 3, middle envelope tool rest; 4, the first knuckle sheet; 5, the second knuckle sheet; 6, end envelope tool rest; 7, chimb; 8, roller; 9, annular groove; 10, clamp clip; 11, contact roller; 12, upright bag former.

The specific embodiment

A kind of square broken line shown in Fig. 1～2 founds the bag forming machine structure, the middle envelope tool rest 3 that comprises support 1, is fixedly installed on square forming tube 2 on the support 1, is provided with along square forming tube 2 length directions, at the first knuckle sheet 4 of square forming tube 2 front sides, seal tool rest 6 at the second knuckle sheet 5 of the first knuckle sheet, 4 front sides, end between the first knuckle sheet 4 and the second knuckle sheet 5.

Shown in Fig. 3～4, the two edges of wherein one group of relative wall of square forming tube 2 stretch out along its width and form four chimbs 7, the junction of adjacent two walls of square forming tube 2 (i.e. four seamed edge places) has pushed against roller 8 respectively, its circumferencial direction of roller 8 upper edges offers annular groove 9, and each chimb 7 is clamped in the corresponding annular groove 9; The four rolling 8 that just can be pushed against on chimb 7 when the bight of film by square forming tube 2 extrudes the square folding lines like this.When film moves forward, by folding the needed left side behind the first knuckle sheet 3 and the second knuckle sheet 5; Seal tool rest 6 sealing-ins and extrude tear mark by end again, and can finish the manufacturing process of a upright bag.

Square forming tube 2 is provided with clamp clip 10 at the rear side that is arranged in envelope tool rest 3, and the length direction that clamp clip 10 prolongs square forming tube 2 extends, and seals tool rest 3 two sides of sealing-in film more accurately in can making like this.

The rear side of square forming tube 2 also is provided with the upright bag former 12 of collar shape, the center line of upright bag former 12 and the axial line of square forming tube 2 coincide, clamp clip 10 is positioned at the bottom of upright bag former 12, a general upright bag former 12 is made vertical collar shape, like this can be so that film can move forward glossily and problem such as can not scratch along upright bag former 12.

Compressed contact roller 11 respectively at least one group of relative outside wall surface in the square forming tube 2, contact roller 11 can make film move along square forming tube 2 forward, and does not produce skew.

Usually, the first knuckle sheet 4 is a rectangle knuckle sheet and along the length direction setting of square forming tube 2, and the second knuckle sheet 5 is a triangle knuckle sheet and along the width setting of square forming tube 2.
