Description
Technical field
The utility model is related to plastic foil processing technique field more particularly to a kind of edge sealing devices.
Background technology
It is each to be widely used in food, building, chemical industry, medicine etc. as a kind of basic material for making packaging bag for plastic foil
A field.When plastic foil is processed into packaging bag, need to carry out banding to plastic foil.At present, it is packed in the market for making
The seal systems of the packing machine of bag, it is most of that tool apron is heated using heat-generating pipe, while heat banding blade；Portions of client is to sealing
It is more demanding, such as seal widths, securely, notch it is neat, and common banding mechanism is because sealing and cut-out are integrated,
It is unable to reach the requirements such as smooth of the width of requirement, firmness and cut-out.
The Chinese invention patent of Publication No. CN104150033A discloses a kind of edge sealing device of packing machine, including separation
The upper girder and lower girder of formula, the upper girder both ends are fixed one group of upper belt roller, are set between the upper belt roller respectively
Folder film upper holder block is equipped with, the lower girder both ends are fixed one group of lower belt roller, are provided between the lower belt roller respectively
Film lower lock block is pressed from both sides, the upper girder middle is equipped with disk calandria, disk sealing knife, institute are included in the disk calandria
Disk calandria lower end is stated equipped with silica gel wheel, on the transport membrane road apart from described silica gel wheel a distance and after sealer
On be provided with cutoff tool, the cutoff tool is by independent heating tube heat supply.Using the inventive technique scheme, the sealing jail of plastic foil
Gu, notch it is neat, effectively reduce banding sealing disqualification rate, improve make packaging bag efficiency.
However, the patent of invention is heated using different heating tubes to disk calandria and cutoff tool, it is desirable to provide more
Heat source, consume big energy, and the patent is squeezed in rotary course using the uniform disk calandria of weight and banding
When disk heating body weight is too small, it is poor to squeeze banding effect for plastic foil；When disk heating body weight is too big, and silica gel wheel can be given
Excessive extruding force is brought, is easily damaged the supporting mechanism that silica gel wheel etc. is located at disk calandria lower part.
Utility model content
The purpose of this utility model is to provide a kind of edge sealing device, the banding mechanism in this edge sealing device does not need to be external
The support of heat source can also seal plastic foil, can effectively reduce energy consumption, and banding mechanism is only being squeezed at banding
Gravity is larger, not only can guarantee banding effect, but can prevent banding mechanism due to overall weight brought to supporting mechanism greatly very much it is excessive
Extruding force and cause supporting mechanism be easily damaged.
In order to achieve the above object, the base case of the utility model is：A kind of edge sealing device, including upper girder and lower master
Beam, the upper girder are equipped with the cylindrical sealing knife that can be rotated, and the lower girder, which is equipped with, is used to support the cylindrical envelope
The supporting mechanism of knife and positioned at the supporting mechanism side, for cutting off the cutoff tool of the membrane substance after banding, the cylinder
