Description

Chamfering machine for packaging bag

Technical Field

The utility model relates to a wrapping bag chamfer field, concretely relates to wrapping bag beveler.

Background

The packaging bag is provided with four sharp corners after being manufactured, so that the packaging bag is not attractive enough in appearance, the sharp corners are easy to scratch hands, and particularly, the possibility of scratching hands is higher for the packaging bag made of a harder material; therefore, the bag needs to be transferred to a cutting station for rounding after the bag is completely manufactured.

The surface area of the upper surface of the current cutting table is larger than that of a packaging bag, waste materials can be left on the cutting table after chamfering is finished, the waste materials need to be cleaned manually when the next packaging bag is chamfered, the chamfering is not convenient, and the chamfering efficiency of the packaging bag can be influenced; and because the area of the surface area wrapping bag of the upper surface of cutting table is big, positional deviation can appear when putting the wrapping bag to operating personnel to lead to the fillet precision of wrapping bag not high.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a be favorable to improving wrapping bag radius angle precision and carry out the beveler of clearing up to the waste material automatically.

In order to achieve the purpose, the technical scheme of the utility model provide a wrapping bag beveler, including frame, brace table and cutting mechanism, cutting mechanism includes and is curved cutting knife many, and the vertical slip of cutting knife sets up in the frame, the surface area of the upper surface of brace table and the big or small phase-match of wrapping bag, and two adjacent sides of brace table and the crossing position fillet transition of upper surface, fillet transition position are located the cutting knife below.

The technical effect of the scheme is as follows: when the packaging bag is rounded, the packaging bag is placed on the upper surface of the supporting table, then the four edges of the packaging bag are aligned with the four edges of the supporting table, and the packaging bag is positioned through the supporting table, so that the rounding precision of the packaging bag can be improved; and after the cutting knife carries out the radius angle to the wrapping bag, the waste material that produces drops from the fillet transition position of a supporting bench, need not the manual work and clears up the waste material on the supporting bench, and is very convenient.

Furthermore, the cutting mechanism further comprises an air cylinder and a supporting plate, the air cylinder is fixed on the rack, an output shaft of the air cylinder is fixedly connected with the supporting plate, and a plurality of cutting knives are fixedly connected with the lower surface of the supporting plate. The technical effect of the scheme is as follows: many cutting knives move along with the backup pad, ensure that many cutting knives cut the wrapping bag simultaneously.

Further, the supporting platform is of a convex shape and comprises a second step. The technical effect of the scheme is as follows: the waste material may be dropped onto the second step of the support table for collection.

Furthermore, baffles are fixedly arranged around the second step of the supporting table. The technical effect of the scheme is as follows: the space that the baffle formed can be collected the waste material, avoids the waste material to scatter.

Further, the upper surface of the baffle is lower than the upper surface of the first step of the support table. The technical effect of the scheme is as follows: it is convenient to place the wrapping bag on the upper surface of first step.

Further, the position where the side surface of the first step is intersected with the upper surface is in right-angle transition. The technical effect of the scheme is as follows: the positioning effect of the first step on the packaging bag is improved.

Furthermore, two adjacent edge arcs of the upper surface of the first step are in arc transition, and the arc length of the arc transition position is smaller than that of the cutting knife. The technical effect of the scheme is as follows: when the cutting knife cuts the packaging bag, the waste material is ensured to be completely separated from the packaging bag.

Furthermore, the lower surface of the supporting plate is fixed with a supporting rod, and the lower end of the supporting rod is fixedly connected with a sponge cushion. The technical effect of the scheme is as follows: when the cutting knife cuts the packaging bag, the stability of the packaging bag is improved.

Further, under the fluffy state of foam-rubber cushion, the lower surface of foam-rubber cushion is less than the lower extreme of cutting knife. The technical effect of the scheme is as follows: when the cutting knife is used for cutting the packaging bag, the spongy cushion is already contacted with the packaging bag.

Furthermore, the lower surface of the spongy cushion is sleeved with a plastic bag. The technical effect of the scheme is as follows: reduce the frictional force between wrapping bag and the foam-rubber cushion, avoid the wrapping bag to adhere to on the foam-rubber cushion and along with the foam-rubber cushion removal.

Detailed Description

The following is further detailed by way of specific embodiments:

reference numerals in the drawings of the specification include: cylinder 1, backup pad 2, cutting knife 3, first step 4, second step 5, baffle 6, bracing piece 7, foam-rubber cushion 8.

The first embodiment is as follows:

the first embodiment is substantially as shown in figures 1-3: the packaging bag chamfering machine shown in fig. 1 comprises a rack, a supporting table and a cutting mechanism, wherein the cutting mechanism comprises an air cylinder 1, a supporting plate 2 and four cutting knives 3, the air cylinder 1 is fixed on the rack through bolts, the type of the air cylinder 1 is RMTL32X200S, and an output shaft of the air cylinder 1 is welded with the supporting plate 2; as shown in fig. 2, each cutting knife 3 is arc-shaped, and four cutting knives 3 are welded at four corners of the lower surface of the supporting plate 2 shown in fig. 1.

The supporting table is positioned below the supporting plate 2, as shown in fig. 3, the supporting table is in a convex shape and comprises a first step 4 and a second step 5, the surface area of the upper surface of the first step 4 is the same as the size of the packaging bag, the two adjacent side surfaces of the first step 4 and the intersecting position of the upper surface are in fillet transition, the fillet transition position is the position shown by C in fig. 3, the two adjacent edge arcs of the upper surface of the first step 4 are in fillet transition, the arc transition position is the position shown by B in fig. 3, and the intersecting position of the side surface of the first step 4 and the upper surface is in right-angle transition; the fillet transition position C is located below the cutting blade 3 as shown in fig. 1, and the cutting edge a of the cutting blade 3 shown in fig. 2 can be brought into contact with the circular arc transition position B shown in fig. 3.
