Description

Packaging film cutting device of heat shrink packing machine {Coating film cutting device of Packing machine}

The present invention relates to a wrapping paper cutting tool of the heat shrink packaging machine, and in particular, to reduce the load transmitted to the drive mechanism by reducing the weight of the cutting tool for cutting the wrapping paper, heat fusion for cutting the heat-sealed wrapping paper The combination and disengagement of the knife is to be performed more stable and convenient.

In general, the heat shrink packaging machine (hereinafter, abbreviated as “packing machine”) includes a frame (1) providing a space in which each component is to be installed, a wrapping paper supply unit (2) for supplying a wrapping paper (P) to a work position, and a wrapping paper. (P) a package supply unit (3) for injecting the package, a packaging unit (4) for heating and fusion cutting the packaging paper (P) in which the package is put, a conveying conveyor (5) for transporting the package (P) in which the package is put, It consists of an operation panel 6 for operating a packing machine.

When the packaging machine P is roll-shaped packaged paper P is mounted and supplied to the packaging paper supplying unit 2, the packaging material is introduced into the packaging paper P from the packaging supplying unit 3, and the packaging is put into the packaging machine P by the transfer conveyor 5. The finished product is taken out by cutting the wrapping paper P transferred to the working position by heat fusion in the packaging section 4.

2 is a side view showing the packaging part.

Referring to FIG. 2, the conventional packing part 4 is provided on a working position where the wrapping paper P is transferred and arrived, and one end of the cutting tool 10 hinged to the frame 1 and the frame ( It is provided with a drive mechanism 20 installed inside 1) to rotate the cutting mechanism 10 up and down.

The cutting tool 10 includes a heating cutting knife 11 having a 'b' shape on the bottom thereof, and the cutting tool 10 is hinged up and down at a point hinged to the frame 1 of the cutting tool 10. The cylinder 21 is installed by the drive mechanism 20 for angular rotation.

Here, the cutting tool 10 is manufactured in the form of an integral cast by the entire casting method, which is adopted to prevent deformation of the shape when the heating cutting knife 11 is heated by an external power source. In the method, the heating cutting knife 11 is mainly coupled by welding or the like to be coupled to the integrated cutting tool 10.

In the conventional packaging unit driving of the above-described configuration, if the package is transported in a state in which the package is put into the wrapping paper (P), the cylinder 21 is driven to rotate the cutting tool (10) by angular fusion knife (11) wrapping paper (P) The heat is melted and cut.

The wrapping paper P cut by heating and melting is moved to the take-out position by the conveying conveyor 5, and this state is automatically performed by the operation of the operation panel or a preset algorithm signal.

The conventional cutting tool described above is manufactured integrally with the casting by the casting method, and thus is made of a heavy material, which causes high load to be transmitted to the cylinder for rotating the cutting tool up and down angularly. There is a problem of excessive power demand and shorten the life of the cylinder.

In addition, the heat fusion knives attached to the cutting tool by the welding method, such as the welding is not detachable, it is difficult to replace when the knife is broken, especially the welding work, which is a representative method of combining the heat fusion knives excessive time in the work itself. The problem is consumed.

The present invention was devised to solve the above problems, the weight of the cutting tool is reduced to reduce the load transmitted to the drive mechanism, such as a cylinder, and the heat-sealed knife is configured to be detachable at any time by performing a simple operation Its purpose is to provide a cutting tool for convenient maintenance.

The present invention has the configuration of the following features to achieve the above object.

The present invention is to supply the wrapping paper from one side on the frame, and put the package in the supplied wrapping paper and transport it to the packaging portion, by rotating the upper and lower angles of the cutting mechanism hinged to the frame by the drive mechanism to form the packaging portion A heat shrink packaging machine for cutting the heat-sealed wrapping paper, the heat shrink packaging machine, the hollow body is formed in the form of a body; A holding part detachably coupled to the body and having a heat fusion knife fixed to a side opposite to an upper surface of the frame; Characterized in that it consists of a fastening portion for detachably connecting the body and the holding portion.

Hereinafter, with reference to the accompanying drawings an embodiment of the present invention to which the feature is applied will be described in detail.

3 is a perspective view of the cutting tool according to the present invention installed on the frame, Figure 4a is a cross-sectional view taken along the line A-A of Figure 3, Figure 4b is a cross-sectional view taken along the line B-B of FIG.

Referring to these drawings, the cutting section 30 of the packaging unit according to the present invention is the body 31 coupled to the frame 1, the holding portion 40 coupled to the body 31, the body 31 and the holding portion Consists of a fastening portion 50 for coupling the 40.

The body 31 is made of a tubular body formed with a hollow inside, which is to maintain the shape of the rectangular tubular body mainly bent in the form of a square plate.

The holding part 40 includes a bracket 41, a side cover 42, and a holder 43.

The bracket 41 maintains a 'c' shape having an open portion to the lower side, the side cover 42 is coupled to both sides of the bracket 41 to form a space of a predetermined interval, between the holder ( 43).

The bracket 41 and the side cover 42 are coupled by fastening members such as bolts, and the holder 43 is coupled to and fixed to the end of the fastening portion 50 penetrating the bracket 41.

Here, the holder 43 is coupled to the heating fusion knife 60 is heated by receiving an external power, between the heating fusion knife 60 and the holder 43 to the holding unit 40 side and heat An insulator 61 is installed to prevent the conduction of interference, and the insulator 61 is made of a ceramic having excellent insulation performance and heat resistance.

The fastening part 50 is composed of a connecting table 51, a spring 52 that is an elastic member.
