Abstract
The utility model relates to a plastic bag making machine, and especially relates to a double-axle fixed-length intermediate heat-seal apparatus. The utility model comprises a heat-seal knife 1, a heat pressing worktable 2, a feeding motor 4, and an adjustable axis of traction 3 arranged on one side of the heat-seal knife 1. The utility model is characterized in that the other side of the heat-seal knife 1 is equipped with a pair of simultaneous fixed-length feeding axises 5 whose surfaces apply and roll; the feeding axis 5 is provided with belt wheels 51 and is connected with the adjustable axis of traction 3 and the feeding motor 4 through a synchronous belt 6. The beneficial effect of the utility model is that a simultaneous fixed-length feeding axis 5 is added, and the plastic film between the adjustable axis of traction 3 and the simultaneous fixed-length feeding axis 5 is in the stably small tension state. In this way, the heat-seal wire is uneasy to elongate or stretch breaking and has stable process quality.
Description
Affiliated technical field
The utility model relates to plastic bag making machine, relates in particular to the mid-hot sealing device of a kind of twin shaft fixed length.
Background technology
Existing polybag Bag Making Machine all is to adopt single shaft traction fixed length, and hot sealing device is positioned at a side of draw-gear.Make the heat-sealing line bear all tractive force like this, easily the heat-sealing line is elongated or breaks, be difficult to produce the thin-film material of weak strength under uneven thickness and the hot sticky state.
Summary of the invention
In order to overcome the deficiency of existing hot sealing device, the utility model provides a kind of twin shaft fixed length mid-hot sealing device, this device can make plastic sheeting seal being in to stablize under the little state of tension, improves the stress of heat-sealing line, improves the quality and the efficient of heat-sealing.
The technical scheme that its technical problem that solves the utility model adopts is: the mid-hot sealing device of a kind of twin shaft fixed length, comprise hot knife 1, hot press working platform 2, feeding motor 4 and be located at the adjustable axis of traction 3 of hot knife 1 one sides, its design feature is: also be provided with the synchronous fixed length feed spool of fitting and roll in a pair of surface 5 in the opposite side of hot knife 1, described feed spool 5 is equipped with belt wheel 51 and by being with 6 to be connected with adjustable axis of traction 3 and feeding motor 4 synchronously.
The beneficial effects of the utility model are, increase synchronous fixed length feed spool 5, then adjustable axis of traction 3 and synchronously one section plastic sheeting between the fixed length feed spool 5 be in and stablize little state of tension.The heat-sealing line is difficult for elongating or breaking stable processing quality like this.Therefore can also improve the operating temperature and the feeding speed of hot knife, improve the efficient of Bag Making Machine.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is a structural representation of the present utility model.
Fig. 2 be the utility model embodiment structural representation.
The specific embodiment
Referring to Fig. 1 and Fig. 2, the mid-hot sealing device of a kind of twin shaft fixed length is installed on the frame 8, comprise hot knife 1, hot press working platform 2, feeding motor 4 and be located at the adjustable axis of traction 3 of hot knife 1 one sides, also be provided with the synchronous fixed length feed spool of fitting and roll in a pair of surface 5 in the opposite side of hot knife 1.Described feed spool 5 is equipped with belt wheel 51 and by being with 6 to be connected with adjustable axis of traction 3 and feeding motor 4 synchronously.Fixed length feed spool 5 surfaces also are provided with rubber bushing synchronously.The course of work of this device is as follows: start feeding motor 4, synchronously with 6 the direction shown in the arrow of the driving lower edge of feeding motor 4 motion and drive adjustable axis of traction 3 and synchronously fixed length feed spool 5 rotate synchronously, the part of film 7 between adjustable axis of traction 3 and synchronous fixed length feed spool 5 is in stable little state of tension owing to be subjected to sync pulling.Hot knife seals action and seals the difficult elongation of line or break stable processing quality.
Above-described specific embodiment only is the utility model preferred embodiment, and the equivalent arrangements of being done according to the utility model claim all should be technology of the present utility model and contains such as.
