Abstract

A bag-making machine hot-cutting and hot-sealing assembly with a hot knife arranged on the lower portion comprises a hot-sealing knife and a base, wherein the base is installed on a machine frame below the hot-sealing knife, a knife groove is formed in the base, the hot knife is installed in the knife groove, two ends of the hot knife are respectively hinged to one end of a lever, the fulcrum of the lever is connected on a support base, a downward pressing rod is connected at two ends of a beam, the lower end of the pressing rod corresponds to the other end of the lever, a shallow groove is formed below the hot-sealing knife, and a round rod is installed in the shallow groove. According to the bag-making machine hot-cutting and hot-sealing assembly with the hot knife arranged on the lower portion, the hot knife is arranged on the base instead of being installed on an original hot-sealing knife, the groove in the middle can be quite shallow and the round rod used for blocking a press cloth is placed in the groove to enable the press cloth to be moved and inserted conveniently, and therefore difficulty in replacing press cloths is reduced; and the hot knife is driven to move vertically by the lever, time difference between hot-sealing and hot-pressing achieved by the hot knife and the hot-sealing knife respectively can be changed by adjusting the height of the lower end of the pressing rod, and therefore different requirements of products with different thicknesses can be met.

Description

Underlying hot knife formula Bag Making Machine earnestly seals assembly

Technical field

The utility model relates to the parts of Bag Making Machine, specifically is that 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, in the longitudinal hole (liner sliding sleeve) on the slide bar 2 slip insertion crossbeams 1, the lower end of slide bar 2 directly (or by secondary back-moving spring 4) connects hot knife 5, below frame base (not shown) is housed, the two ends of crossbeam 1 are connected 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 by drive unit (not shown) and move up and down, and then drive crossbeam 1 and hot knife 5 is synchronized with the movement up and down.Below hot knife 5, be provided with the cutter groove, hot knife 9 is installed in the cutter groove.In the both sides that earnestly seal assembly boiling hot cloth spool 13 is housed, boiling hot cloth 14 passes the upper end of hot knife 9 in the 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 the cutter groove below the hot knife 5 is very dark, is difficult for the mobile cloth 14 that scalds, and changes and be difficult for when scalding cloth it is passed the upper end of hot knife 9, very trouble.

Summary of the invention

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

The technical solution of the utility model is: a kind of underlying hot knife formula Bag Making Machine earnestly seals assembly, comprise hot knife and base, frame below hot knife is equipped with base, it is characterized in that, on described base, be provided with the cutter groove, in the cutter groove hot knife is housed, each is hinged with an end of a lever at the two ends of hot knife, and the fulcrum of lever is hinged on the 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 lead.

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

Described lever is herringbone.

At described lever back-moving spring is housed.

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

The specific embodiment

Referring to Fig. 1 and Fig. 2, a kind of underlying hot knife of the utility model formula Bag Making Machine earnestly seals assembly, comprises hot knife 5 and base 8, and the frame 7 below hot knife 5 is equipped with base 8.Be provided with one deck silica gel 19 on described base 8, the centre is provided with cutter groove 81, in this cutter groove 81 hot knife 9 is housed, and each is hinged with an end of a lever 10 at the two ends of hot knife 9, and the fulcrum of lever 10 (axle) 20 is hinged on the 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 be connected with the two ends of hot knife 5, leave the gap between round bar 15 and shallow slot 18 inboards).Depression bar 6 can up-down adjustment, as being fixed in the through hole of crossbeam 1 with two nuts 21.Leave the gap between the cutter groove 81 of hot knife 9 and base 8, guarantee the electric insulation between hot knife 9 and other members.Also to insulate between lever 10 and the hot knife 9 (as establishing 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 lead (flexible cord) 16.
