In addition, the processing of mould and repairing must be finished by specialized factory, and the cycle is long, the cost height.One secondary pneumatic die rises for 2000 yuan, and machine die also wants 800 yuan to rise.Die life is short, and machine die 1,000,000 times, pneumatic die will be repaired for 4,000,000 times, otherwise just hidden danger of quality be arranged usually.In case fault is arranged, the repairing time needs 3-7 days usually.If pneumatic piercer also needs external air compressor machine and pipeline, cost height, expense are big.
In addition, the noise of punching press is very big, when many machines are worked together, is difficult to stand, and long period of operation can influence staff's health.
In view of there are many defectives in traditional card punch, the inventor designs a kind of brand-new card punch, avoids the problems referred to above, and this case produces thus.
The utility model content
The purpose of this utility model is to provide a kind of heat shrinkage film packaging bag hot card punch, and it is easy to punch, and position, quantity, the size of pore can be set arbitrarily, and pore quality height, and the edge is difficult for adhesion, and the card punch cost is low, long service life.
To achieve these goals, the scheme that the utility model adopted:
The hot card punch of heat shrinkage film packaging bag comprises heater and vent needle, and vent needle is fixed on the heater, the external control heater power regulating switch of heater.
The hot card punch of described heat shrinkage film packaging bag also comprises the tongue piece and the collet that have corresponding eyelet respectively, and tongue piece is between film, the tongue piece eyelet is relative with the position of vent needle, collet is positioned under tongue piece and the film, supporting tongue piece and film, and the collet eyelet is relative with the position of tongue piece eyelet.
Described heater is fixed in the actuating unit, and actuating unit comprises crossbeam and support, and the crossbeam two ends are fixed on the up and down support, and heater is installed on the crossbeam; Vent needle below on the heater is open and flat film on the film frame.
Described film frame is two horizontal thin film deflector rolls, and film is walked around the top of film deflector roll, is wound up into then in the feeding nip rolls of Bag Making Machine.
Have a plurality of deflector rolls between described feeding nip rolls and the horizontal thin film frame.
Described heater is the electric iron heater.
An affixed heat conduction needle stand on the nib of described electric iron heater, vent needle is solidly plugged on the heat conduction needle stand.
Described electric iron heater nib and heat conduction needle stand adopt the good brass of thermal conductivity to make.
After adopting such scheme, the utility model has been avoided the form of die punching in the traditional approach, after being heated with vent needle, beats on film packaging bag, forms pore.Resulting pore edge is melted by hot glue in the utility model, forms neat edge, and can not cause breach to tear, and quality improves greatly.Pore opening, quantity, position also no longer are limited by mould, by the vent needle of heat time heating time, heating-up temperature and installing different-diameter is set, can get the pore that varies in size.The position of heater and vent needle is depended in the position of pore, needs pore quantity many more, and vent needle quantity is many more.
In addition, the center-fold sheet that uses in the banding bag is two superimposed, therefore between double-layer films, lay a tongue piece and a collet, on tongue piece, have the eyelet corresponding with vent needle, tongue piece places up and down between the double-layer films, double-layer films and tongue piece place on the collet, and when tongue piece effectively prevented the punching heating, double-layer films was welded together.Collet prevents that tongue piece gravity sag and film lower floor elasticity from dodging and causes punching incomplete that tongue piece plays vertical spacing and supporting role to film jointly with collet.
Heater can adopt simple electric iron repacking, and cost is low, and is easy to make.Simultaneously heater can be installed in the executing agency on traditional mechanical punching device, forms to go up down and moves, and repacking is simple.Two horizontal thin film deflector rolls horizontally-guided and supportings when film punches cooperate the acting in conjunction of other deflector rolls to make that the film feeding is steady, prevent wrinkling.
