The implementation principle of the embodiment is as follows:

the materials to be packaged are poured through the feeding hole 30, the packaging paper raw materials are placed on the rotating rod 33, part of packaging paper is manually pulled to be wound on the guide rod 35 and vertically pulled to the inner part of the bag pulling wheel 40, the packaging bag is kept to have a certain tensile force in the pulling process, the phenomenon that the surface of the packaging bag is more wrinkled after the packaging bag is formed due to the fact that the packaging paper is loose in the packaging process is avoided, and the packaging bag is attractive in appearance and has sealing performance.

In addition, the wrapping paper pulled into the vertical packaging device is bent in half, so that the vertical packaging of the wrapping paper is convenient.

The packaging machine is started, the raw materials of the packaging paper are guided through the guide device 34, the packaging paper is straightened under the rotation of the bag pulling wheel 40, the vertical packaging mechanism 37 starts packaging, the vertical side of the packaging paper is sequentially subjected to hot melting packaging through the continuous reciprocating motion of the vertically placed hot melting plate 38, so that the packaging paper is formed into the vertical strip-shaped connected packaging bag 31 with a packaging edge, and the defects that the packaging edge packaging effect of the packaging paper is poor and the packaging bag is poor in sealing performance are avoided.

The bag pulling is continued by the bag pulling wheel 40 until the packaging bag is pulled into the transverse packaging mechanism 36, the packaging bag is packaged by the transversely arranged hot melting plate 38, the packaging bag with the vertical packaging edge is transversely packaged, the buffer mechanism 361 effectively buffers violent collision during transverse packaging, the stability of the packaging process is ensured, so that the bottom of the strip-shaped packaging bag is provided with the sealed transverse packaging edge, and at the moment, the hopper 26 feeds materials into the packaging bag.

After the feeding is finished, the packaging bags are continuously pulled by the bag pulling device 3 to move downwards until the connected packaging bags 31 are pulled to the set length of the packaging bags, the transverse packaging mechanism 36 packages the connected packaging bags again, the connected packaging bags are transversely packaged to transversely package the side edges, and at the moment, the packaging bags with the transverse packaging edges and the vertical packaging edges are formed. The bag pulling wheel 40 continues to pull the bags.

Until the conjoined packing bag 31 is pulled into the punching device 4, the transverse packaging edge of the conjoined packing bag 31 is right opposite to the punching die holder and is tightly attached to the surface of the punching die holder, the punching device 4 punches the transverse packaging edge, two positioning holes 43 are punched on the transverse packaging edge, the positioning holes 43 are round holes, and the state of the conjoined packing bag 31 after punching is referred to fig. 9.

After the punching is finished, the connected packaging bag 31 is continuously pulled by the bag pulling wheel 40 until the punched transverse packaging edge is pulled into the punching device 5, and the pulling wheel stops rotating. At this time, the transverse sealing edge falls between the fixing plate 7 and the pressing piece 6 and is tightly attached to the surface of the fixing plate 7.

Stamping device 5 carries out the punching press, first cylinder drive compresses tightly 6 and moves towards fixed plate 7, setting element 61 runs through the locating hole 43 on horizontal encapsulation edge, compress tightly disjunctor wrapping bag 31 on fixed plate 7 until compressing tightly 6, the pilot pin runs through in locating hole 43 and with the cooperation of pegging graft of through-hole 9 on fixed plate 7 this moment, make horizontal encapsulation edge comparatively firmly sticis on fixed plate 7, guarantee the stability when follow-up punching press effectively, prevent rocking of disjunctor wrapping bag 31 and lead to the inaccurate punching press position to make the punching press dislocation situation take place.

After the transverse packaging edge is compressed tightly on the fixing plate 7 by the compression block, the second cylinder drives the stamping part 10 to move towards the fixing plate 7, and the stamping part 10 is prevented from dropping due to self gravity under the longitudinal limiting effect of the limiting strip 22, so that the situation that the stamping part 10 is not corresponding to the slot 13 and is staggered in stamping is prevented.

At this moment, the stamping part 10 moves towards the fixing plate 7, the stamping part 10 enters the through groove 12, until the stamping part 10 penetrates through the fixing plate 7, meanwhile, the stamping part 10 punches out the hot melting part 42 on the connected packaging bag 31, and then the excess material of the hot melting part 42 of the connected packaging bag 31 is punched out, the excess material continues to move forwards along with the insertion of the stamping part 10 into the slot 13, until the stamping part 10 moves to the bottom of the slot 13, the movement is stopped for a period of time and the slot 13 is ready to be withdrawn, at this moment, the stamping part 10 tightly presses the excess material on the bottom of the slot 13, until the stamping part 10 withdraws from the slot 13, when the excess material does not receive the pressure of the stamping part 10, the excess material vertically drops downwards under the effect of self gravity, and is discharged to the discharge. The state of the punched connected packaging bag is shown in fig. 10, and the state of the excess material is shown in fig. 11.

The connected packaging bag 31 is punched by the I-shaped stamping part 10, the transverse packaging edge is disconnected from the middle part, and the four corners at the disconnection part form round corners 39 and the round corners 39 on the same edge are symmetrically arranged.

The conjoined packing bag 31 is punched again by the punching device 5 to form a single packing bag with four corners being relatively round corners 39, and is discharged onto the discharge chute 24.

And after all the connected packaging bags 31 are punched and packaged, the packaged packaging bags are collected from the discharge chute 24, the excess materials are discharged through a gap 45 formed by the blocking plate 25 and the discharge chute 24, and a plurality of formed packaging bags are blocked on the discharge chute 24 and are convenient to collect.

This fillet packagine machine is different from current fillet packagine machine, and current fillet packagine machine all lacks hold-down mechanism 53, and rocking and making whole swing easily of disjunctor wrapping bag 31, therefore the punching press often causes the phenomenon of dislocation to take place. And this fillet packagine machine punches a hole through punching device 4 to the hot melt portion 42 of disjunctor wrapping bag 31 to two circular shape locating holes 43 have been seted up on making hot melt portion 42, run through locating hole 43 by the setting element 61 on hold-down mechanism 53 again and fix a position and compress tightly with fixed plate 7 the hot melt portion 42 of disjunctor wrapping bag 31, make disjunctor wrapping bag 31 can not rock at the in-process of punching press, thereby guarantee to punch on hot melt portion 42 and can not cause the dislocation, and it is more nimble to set up this fillet packagine machine through the discharge gate 23 of seting up on the piece 6 and use.

The embodiments of the present invention are preferred embodiments of the present invention, and the scope of the present invention is not limited by these embodiments, so: all equivalent changes made according to the structure, shape and principle of the invention are covered by the protection scope of the invention.
