Description
Technical field
The present invention relates to the part of Bag Making Machine, it is specifically a kind of before and after knife be capable of the Bag Making Machine hot knife group of independent temperature control
Part.
Background technology
Existing Bag Making Machine seals the structure of knife assembly referring to Fig. 1 and Fig. 2, in crossbeam 1（It is connected with frame by support 8）Under
Side passes through guiding mechanism（Guide post 2 and the first spring 20）It is connected with hot knife 3, equipped with boiling hot cloth adjustment mechanism on hot knife 3
（Spool 4, boiling hot cloth 6）；Hot knife 3 is provided with front knife 31 and rear knife 32, and base 9 is housed in the frame 10 of lower section.Front knife 31 is with after
Knife 32 is structure as a whole, and is provided with therebetween cutter groove（Cutting knife 7 is accommodated, the two ends of cutting knife 7 are connected with guide post 5 and crossbeam are flexible
Connect）.As hot knife 3 is structure as a whole, its temperature can not be controlled respectively, and as the outside of rear knife 32 is provided with blower（With
In conveying heat-sealing and the product cut）, cause rear knife to radiate more, temperature is less than front knife；Other factors will also result in front knife with
The temperature difference of knife afterwards.The temperature of knife is relatively low afterwards can cause before and after's knife heat-sealing speed or effect different, if front hot-sealing line is suitable,
Then the connection of post heat-seal line is just insecure, if rear knife temperature is suitable, front knife temperature is too high, causes hot-sealing line to disconnect, and produces useless
Product.
In addition, scald cloth adjustment mechanism being：A spool 4 is respectively installed in the both sides of hot knife 3, the two ends for scalding cloth 6 are connected to two
On the spool 4 of side.Often using a period of time after, the boiling hot cloth 6 positioned at knife blade before and after hot knife 3 will be damaged, need to be frequently by
Cloth 6 is scalded in the movement of rotating scroll 4.Which has the drawback that：Boiling hot cloth 6 is used（Adjustment）During will be through knife knife before and after hot knife 3
Sword, scalds cloth 6 where the damage of front knife 31, it is easy to overlap with blade or be close in Hou Daochu, and its result can cause boiling hot cloth to exist
Rupture herein or product is caused damage, reduce yield rate.
Further, hot knife 3 is operationally very big with the temperature difference of off working state, expand with heat and contract with cold substantially, existing heat-sealing
The attachment means of knife 3 and crossbeam 1（Guiding mechanism）Without pipe length compensating structure, expand with heat and contract with cold and can cause the deformation of mechanical mechanism,
Affect normal work and reduce product quality, hot knife when serious, can be caused to work.
The content of the invention
The present invention is intended to provide knife is capable of the Bag Making Machine heat-sealing knife assembly of independent temperature control before and after a kind of, to solve prior art
The front knife for existing causes before and after's knife heat-sealing speed or effect different from the temperature difference of rear knife, easily causes hot-sealing line disconnection, produces
Raw waste product；Boiling hot cloth is easy to overlap in blade or be close in rear knife, and its result can cause to scald cloth fracture or product is caused to damage
Evil, reduces yield rate；And hot knife does not have pipe length compensating structure, can cause the deformation of mechanical mechanism, affect normal work and
Reduce the problem of product quality.
The technical scheme is that：Before and after a kind of, knife is capable of the Bag Making Machine heat-sealing knife assembly of independent temperature control, in crossbeam
Lower section is connected with hot knife by guiding mechanism；Hot knife is provided with front knife and rear knife, it is characterised in that described front knife and rear knife
For absolute construction, the two ends of the two are connected with each other with connecting plate；Gap is provided between the front knife and rear knife；In described front knife
With electric heater is respectively provided with the outside of rear knife, each electric heater is respectively equipped with temperature regulating device, to front knife and the heating-up temperature of rear knife
Control respectively.
Elongated hole corresponding with described gap is provided between the top and bottom of the crossbeam；In described crossbeam and hot knife
Both sides are respectively mounted a set of boiling hot cloth adjustment mechanism in front and back.
Described boiling hot cloth adjustment mechanism is made up of two pairs of upper winding shafts, two pairs of lower winding shafts and boiling hot cloth, the length on the crossbeam
The both sides in hole are respectively provided with a upper winding shaft, are respectively provided with a lower winding shaft, in every side on the outside of the front knife and rear knife
Respectively equipped with cloth is scalded between upper winding shaft and lower winding shaft, the upper end of each boiling hot cloth is connected with upper winding shaft, and the lower end for scalding cloth is worn downwards successively
The gap crossed between the elongated hole of crossbeam and the front knife and rear knife, is flipped up further around the bottom of excessively front knife or rear knife, with respective side
Lower winding shaft connection.
The two ends of described upper winding shaft and lower winding shaft are respectively supported in gripper shoe, in the upper winding shaft and one end of lower winding shaft
Or two ends are provided with screw thread, and fastened with nut.
Described guiding mechanism is made up of guide post and the first spring, and the upper end of guide post slides through described crossbeam,
The lower end of guide post is connected with the top surface of hot knife, on the guide bar equipped with the first spring；The guide post and the first spring are equipped with
Two sets.
The lower end of the guide post at least described in is connected with the middle part of a compensating plate, in the compensating plate of the guide post both sides
On be respectively provided with an elongated hole；Connect two fix bars corresponding to the elongated hole in the top surface of described hot knife, in the fix bar
Top be provided with outward flange, in the fix bar between the outward flange and compensating plate be equipped with second spring.
It is an advantage of the invention that：Front knife is separated with rear knife, centre is provided with gap, front knife and rear knife are heated respectively and controlled
Temperature so that the two has essentially identical temperature, effectively prevent both temperature difference and causes hot-sealing line to disconnect, produces showing for waste product
As；Using two sets of independent boiling hot cloth adjustment mechanisms, thoroughly avoiding boiling hot cloth breakage and overlapping causes to scald cloth fracture or product is made
Into the phenomenon of infringement, yield rate is improve；No pipe length compensating structure between hot knife and crossbeam, it is to avoid hot knife flatulence of heat type is cold
Contracting machine causes tool deformation, it is ensured that the normal work and product quality of hot knife.
