Abstract

The invention relates to a hot-sealing mechanism of a bagging machine. A lifting mechanism is arranged above a film cushion plate; installing plates are horizontally fixed on the lifting mechanism; a hot-sealing cutter is vertically arranged at the lower surface of the installing plate and is opposite to the film cushion plate; a pair of through holes are symmetrically arranged on the installing plates positioned at the two sides of the hot-sealing cutter; each through hole is internally provided with a guide column in a hanging manner; the upper end of each guide column penetrates through the through hole; the top part of each guide column is connected with a locking nut in a rotating manner; the lower end of each guide column is provided with a spring in a sheathing manner; the bottom end of each guide column is horizontally and fixedly provided with a water cooling plate; the upper ends of the springs are contacted with the lower surfaces of the installing plates, and the lower ends of the springs are contacted with the upper surfaces of the water cooling plates; and the water cooling plates are opposite to the film cushion plate and are respectively provided with a water cooling cavity. Cold prepressing is carried out on a heat-shrinkage film product by arranging the water cooling plates, so that when the hot-sealing cutter is contacted with the film surface of the heat-shrinkage film product, the temperature of the surface of the product can not be increased in a large range, and the shrinkage amount of the film surface in the hot-sealing process can be effectively controlled.

Description

The Bag Making Machine heat sealing mechanism
Technical field
The present invention relates to multilayer coextruding pyrocondensation film back segment production process equipment, relate in particular to the Bag Making Machine heat sealing mechanism.
Background technology
At present, thermal shrinkage type high barrier food package film is mainly used in the packing of cold fresh meat, seafood food.
The heat shrinkage film bag-making equipment is of a great variety on the market, wherein in heat seal process, because face will touch high temperature inevitably, shrinks so face has to some extent, and the sack profile after causing being shaped is not attractive in appearance, and disunity.How realizing the heat-sealing of shrink film, and reduce the thermal shrinking quantity of goods in the heat seal process as far as possible, is a great problem of present industry.Therefore, the optimization to existing equipment improves extremely urgent.
Summary of the invention
The objective of the invention is to overcome the deficiency that prior art exists, a kind of Bag Making Machine heat sealing mechanism is provided.
The object of the invention is realized through following technical scheme:
The Bag Making Machine heat sealing mechanism; Characteristics: above the film backing plate, be provided with elevating mechanism; Horizontal fixed has installing plate on the elevating mechanism; The centre of installing plate lower surface is vertically installed with hot knife; Hot knife is right against the film backing plate; Be positioned at that symmetry has a pair of through hole on the installing plate of hot knife both sides; All be hung with guide pillar in each through hole; Through hole is all passed in the upper end of each guide pillar; The top ends of each guide pillar all is connected with locking nut; The lower end of each guide pillar all is equipped with spring; The equal horizontal fixed in the bottom of each guide pillar has the cold water plate, and the upper end of said spring contacts with the lower surface of installing plate, and the lower end of said spring contacts with the upper surface of cold water plate; Said cold water plate is right against the film backing plate, is equipped with cold water cavity in each cold water plate.
Further, above-mentioned Bag Making Machine heat sealing mechanism, wherein, the cold water cavity in said each cold water plate is all through pipeline connection Cold water supply system.
The substantive distinguishing features of technical scheme of the present invention is mainly reflected in progressive:
Through around the heat-sealing calandria, the cold water plate being set the heat shrinkage film goods are carried out cold prepressing; Make heat shrink films before heat-sealing, get into low-temperature condition; When hot knife contacts with heat shrinkage film goods face; Be unlikely to the large-scale temperature of product surface is raise; Thereby controlled the amount of contraction of face in the heat seal process effectively; Make the sack uniform specification property of moulding higher, be more conducive to carrying out automatically of later process.Improve the appearance characteristics of product greatly, significantly improved prouctiveness.
Description of drawings
Below in conjunction with accompanying drawing technical scheme of the present invention is described further:
Fig. 1: structural representation of the present invention.
The specific embodiment
As shown in Figure 1; The Bag Making Machine heat sealing mechanism; Above film backing plate 7, be provided with elevating mechanism 8; Horizontal fixed has installing plate 1 on the elevating mechanism 8; The centre of installing plate 1 lower surface is vertically installed with hot knife 5; Hot knife 5 is right against film backing plate 7; Be positioned at that symmetry has a pair of through hole on the installing plate of hot knife both sides; All be hung with guide pillar 2 in each through hole; Through hole is all passed in the upper end of each guide pillar 2; The top ends of each guide pillar all is connected with locking nut; The lower end of each guide pillar 2 all is equipped with spring 3; The equal horizontal fixed in the bottom of each guide pillar 2 has cold water plate 4; The upper end of spring 3 contacts with the lower surface of installing plate 1, and the lower end of spring 3 contacts with the upper surface of cold water plate 4, and cold water plate 4 is right against film backing plate 7; Be equipped with cold water cavity in each cold water plate 4, the cold water cavity in each cold water plate is all through pipeline connection Cold water supply system.
During concrete the application; Elevating mechanism 8 drive installing plates 1 press down or rise, and when pressing down, will charge into low-temperature circulating water in the two cold water plate cold water cavities earlier; Heat shrinkage film goods 6 place on the film backing plate 7; The cold water plate 4 of installing plate 1 descending drive guide pillar 2 bottoms is descending, and cold water plate 4 is earlier with 6 compactings of heat shrinkage film goods, and installing plate 1 continues descending; The upper end of guide pillar 2 and installing plate 1 are separated; Spring 3 is in compressive state, and hot knife 5 continues to press down, and the heat shrinkage film goods 6 of bilayer is pressed to film backing plate 7 seal rapidly.
This mechanism is provided with the cold water board component of inner flow passage; Make heat shrink films before heat-sealing, get into low-temperature condition; When hot knife 5 contacts with heat shrinkage film goods face; Be unlikely to the large-scale temperature of product surface is raise; Thereby controlled the amount of contraction of face in the heat seal process effectively; Make the sack uniform specification property of moulding higher, be more conducive to carrying out automatically of later process.
In sum, the present invention is novel in design, through around the heat-sealing calandria, the cold water plate being set the heat shrinkage film goods is carried out cold prepressing, seals, thereby effectively controls the amount of contraction of making mouth in the bag process, guarantees sack good surface appearance characteristic; Normal operation to Bag Making Machine provides powerful guarantee, has improved the appearance characteristics of product greatly, improves prouctiveness.
What need understand is: the above only is a preferred implementation of the present invention; For those skilled in the art; Under the prerequisite that does not break away from the principle of the invention, can also make some improvement and retouching, these improvement and retouching also should be considered as protection scope of the present invention.
