Abstract

The utility model discloses a cutting mechanism for automatic woven bag-sewing machines, which comprises a movable cold-cutting cutter and a fixed cold-cutting cutter fixed on a support, a hot cutter holder is arranged over the fixed cold-cutting cutter and can be driven by a double-stroke cylinder to move up and down along a linear track, and a hot cutter is arranged at a position under the hot cutter holder, which corresponds to the back of the fixed cold-cutting cutter. The cutting mechanism has the advantages that because the hot cutter driven by the double-stroke cylinder is arranged over the fixed cold-cutting cutter, the back of the fixed cold-cutting cutter is utilized as a lower support plate for the hot cutter, a function combining cold cutting and hot cutting is realized, and the layout is compact, so that a space can be effectively and reasonably utilized.

Description

The automatic sartorius cutter sweep of woven bag

Technical field

The utility model relates to the automatic sartorius of woven bag, especially relates to the automatic sartorius cutter sweep of a kind of woven bag.

Background technology

In woven bag production process, woven bag, due to the difference of processing technology and material, can be divided into two kinds of cutting methods.Be with the cutting of metal sharp weapon, be called cold cut; Be a metal cutting that utilizes heating, be called earnestly.Common woven bag cold cutting system and hot-cutting device are the devices that two covers are independently installed, and take very large space in workshop, and layout is unreasonable.

Summary of the invention

It is a kind of easy to use that the utility model object is to provide, and not only can carry out cold cut but also can carry out the automatic sartorius cutter sweep of fervent woven bag.

For achieving the above object, the utility model can be taked following technical proposals:

The automatic sartorius cutter sweep of woven bag described in the utility model, comprise cold cut movable blade and be fixed on the cold cut dead knife on support, above described cold cut dead knife, be provided with hot knife fixed mount, described hot knife fixed mount is driven and to be moved up and down along line slideway by double stroke cylinder, below described hot knife fixed mount over against answering cold cut dead knife knife back position to be provided with hot knife.

The utility model advantage is the hot knife driving by be provided with double stroke cylinder above cooling dead knife, utilize cooling dead knife the knife back as the lower bolster of hot knife, realized cold cut and fervent shared function, compact in design, space has obtained effective and reasonable utilization.

Accompanying drawing explanation

Fig. 1 is structural representation of the present utility model.

Fig. 2 is the A-A section structure schematic diagram of Fig. 1.

The specific embodiment

As shown in Figure 1, 2, the automatic sartorius cutter sweep of woven bag described in the utility model, comprise cold cut movable blade 1 and be fixed on the cold cut dead knife 3 on support 2, above described cold cut dead knife 3, be provided with hot knife fixed mount 6, described hot knife fixed mount 6 is driven and is moved up and down along line slideway 5 by double stroke cylinder 4, below described hot knife fixed mount 6 over against answering cold cut dead knife 3 knife back positions to be provided with hot knife 7.When carrying out cold cut, first utilize the piston rod of double stroke cylinder 4 to drive hot knife 7 all to regain and arrive limes superiors position, for cold cutter movable blade 1 is vacateed activity space; When fervent, the piston rod of double stroke cylinder 4 first stretches out the upper position of cylinder arriving when fervent, then continue to reach bit positions under the cylinder that hot knife 7 contacts with cold cut dead knife 3 knife back, finally by double stroke cylinder 4 drive hot knives 7 at cylinder upper and cylinder the next between reciprocating motion, carry out woven bag earnestly.

Claims

1. the automatic sartorius cutter sweep of woven bag, comprise cold cut movable blade (1) and be fixed on the cold cut dead knife (3) on support (2), it is characterized in that: in described cold cut dead knife (3) top, be provided with hot knife fixed mount (6), described hot knife fixed mount (6) is driven and to be moved up and down along line slideway (5) by double stroke cylinder (4), in described hot knife fixed mount (6) below over against answering cold cut dead knife (3) knife back position to be provided with hot knife (7).
