Abstract

A lower hot-knife-type bag machine hot-cutting heat-seal assembly comprises a hot-seal knife and a base, wherein the base is arranged on a rack below the hot-seal knife. A knife groove is formed in the upper surface of the base, a hot knife is arranged in the knife groove, two ends of the hot knife are respectively hinged with one end of a lever, and the fulcrum of the lever is connected with a support. Compression bars downward are connected with two ends of a beam, and the lower ends of the compression bars are corresponding to the other ends of the levers. A shallow slot is formed below the hot knife, and a round bar is arranged in the shallow slot. The lower hot-knife-type bag machine hot-cutting heat-seal assembly has the advantages that the hot knife is arranged on the base, the prior hot-seal knife is not provided with the hot knife, a middle groove can be shallow, the round bar ( for warding a hot cloth) is placed in the groove, the hot cloth is easy to move and insert, and the difficulty of changing the hot cloth is reduced; the hot knife moves up and down through the lever driving, the lower end heights of the compression bars are adjusted, time difference of the hot knife and the hot-seal knife when hot-seal and hot-press can be changed, and different requirements of products with different thicknesses can be met.

Description

Underlying hot knife formula Bag Making Machine earnestly seals assembly

Technical field

The present invention relates to the parts of Bag Making Machine, specifically a kind of underlying hot knife formula Bag Making Machine earnestly seals assembly.

Background technology

Existing Bag Making Machine earnestly seals assembly referring to Fig. 3, primary structure comprises crossbeam 1, slide bar 2, back-moving spring 3 and hot knife 5, slide bar 2 slides and inserts in the longitudinal hole (liner sliding sleeve) on crossbeam 1, the lower end of slide bar 2 directly (or by secondary back-moving spring 4) connects hot knife 5, below frame on base (not shown) is housed, the two ends of crossbeam 1 are connected to the upper end of guide post 12, it is not shown that its lower end slides through frame 7(Fig. 3, with reference to figure 1), and drive guide post 12 to move up and down by drive unit (not shown), and then drive crossbeam 1 and hot knife 5 to be synchronized with the movement up and down.Below hot knife 5, be provided with cutter groove, hot knife 9 is installed in cutter groove.Be equipped with and scald cloth spool 13 in the both sides that earnestly seal assembly, scald the upper end of cloth 14 through hot knife 9 in cutter groove, scalding cloth 14 two ends is connected on the boiling hot cloth spool 13 of both sides, after every use a period of time, the boiling hot cloth 14 that is positioned at hot knife 9 blades will damage, and needs often to move boiling hot cloth 14 by rotating boiling hot cloth spool 13.Because hot knife 5 cutter groove is below very dark, be difficult for the mobile cloth 14 that scalds, and change the upper end that is difficult for being passed hot knife 9 while scalding cloth, very trouble.

Summary of the invention

The present invention aims to provide a kind of underlying hot knife formula Bag Making Machine and earnestly seals assembly, the boiling hot cloth of movement and the boiling hot pretty troublesome problem of cloth of replacing that exist to solve prior art.

Technical scheme of the present invention is: a kind of underlying hot knife formula Bag Making Machine earnestly seals assembly, comprise hot knife and base, in frame below hot knife, base is housed, it is characterized in that, on described base, be provided with cutter groove, in cutter groove, hot knife is housed, the two ends of hot knife are each hinged with one end of a lever, and the fulcrum of lever is hinged on bearing by fulcrum shaft; Be connected with downward depression bar at the two ends of crossbeam, the lower end of depression bar is corresponding with the other end of this lever; Below hot knife, be provided with shallow slot, round bar is housed in shallow slot.

Described hot knife two ends connect heating power supply by wire.

Bearing is equipped with in lower end at described depression bar.

Described lever is herringbone.

On described lever, back-moving spring is housed.

Advantage of the present invention is: hot knife is located on base, hot knife is not installed on hot knife originally, middle groove can be very shallow, insert groove with round bar (for blocking boiling hot cloth), be easy to the mobile cloth that scalds, also easily insert and scald cloth, reduced and changed the difficulty of scalding cloth; Hot knife moves up and down by lever actuated, by regulate the lower end height of depression bar can change hot knife and hot knife sealing and time difference when hot pressing, can meet the different needs of different-thickness product.

Detailed description of the invention

Referring to Fig. 1 and Fig. 2, a kind of underlying hot knife of the present invention formula Bag Making Machine earnestly seals assembly, comprises hot knife 5 and base 8, in the frame 7 below hot knife 5, base 8 is housed.On described base 8, be provided with one deck silica gel 19, centre is provided with cutter groove 81, in this cutter groove 81, hot knife 9 is housed, and the two ends of hot knife 9 are each hinged with one end of a lever 10, and the fulcrum (axle) 20 of lever 10 is hinged on bearing 11.Be connected with downward depression bar 6 at the two ends of crossbeam 1, the lower end of depression bar 6 is corresponding with the other end of this lever 10.Below hot knife 5, be provided with shallow slot 18, its two ends of round bar 15(be housed in shallow slot and be connected with the two ends of hot knife 5, between round bar 15 and shallow slot 18 inner sides, leave gap).Depression bar 6 can up-down adjustment, as being fixed in the through hole of crossbeam 1 with two nuts 21.Between the cutter groove 81 of hot knife 9 and base 8, leave gap, ensure the electric insulation between hot knife 9 and other members.Between lever 10 and hot knife 9, also to insulate (as established one deck abrasion-proof insulating material on fulcrum shaft 20 surfaces, as pottery etc.).

In the lower end of described depression bar 6, bearing 17 is housed, described lever 10 is herringbone (shape that V turns around), can reduce the noise that bearing 17 contacts with lever 10.

Described hot knife 9 two ends connect heating power supply (not shown) by wire (flexible cord) 16.

Back-moving spring 18 is housed below the outer end of described lever 10, and back-moving spring 18 also can be mounted in the torsion spring on lever 10 fulcrum shafts 20.

When applying, the present invention is connected with the lower end direct (or by secondary back-moving spring 4) of a slide bar 2, slide bar 2 slides and inserts in the longitudinal hole (liner sliding sleeve) on crossbeam 1, back-moving spring 3 is housed on slide bar 2, in the frame 7 below hot knife 5, base 8 is housed.The two ends of crossbeam 1 are connected to the upper end of guide post 12, slide through below frame 7 in the lower end of guide post 12, when work by drive unit (not shown) driving guide post 12 move up and down (being above prior art).In the time of work, after hot knife 5 rises, need film processed (workpiece) be transported to base 8 and hot knife 9 above, hot knife 5 declines and contacts above with base 8, by workpiece heat-sealing (at the both sides of hot knife 9 heat-sealing twice hot-sealing line), the bottom end bearing 17 of depression bar 6 presses down the outer end of lever 10 simultaneously, and lever 10 drives hot knife 9 to move up, workpiece is cut between two hot-sealing lines, complete and once seal fervent process.
