Embodiment Construction
[0020] The principles and features of the present invention are described below in conjunction with the accompanying drawings, and the examples given are only used to explain the present invention, and are not intended to limit the scope of the present invention.
[0021] Such as figure 1 As shown, a sealing device for a packaging machine, which includes a main combination roller 1, a slave combination roller 2, and a bracket 3; the main combination roller 1 and the slave combination roller 2 are engaged by gears Connection; the sealing device realizes the vertical and horizontal sealing of the packaging bag through the relative rotation between the main combination roller 1 and the secondary combination roller 2 . Preferably, the sealing device is also provided with a locking bolt 33 for adjusting the gap between the main assembly roller 1 and the slave assembly roller 2 .
[0022] The main combination roller 1 is driven by an external power source, and the main combination ...

The invention relates to a sealing device for a packing machine. The sealing device comprises a main combination roller, a slave combination roller and a bracket, wherein the main combination roller and the slave combination roller are in engaged connection through a gear; the main combination roller comprises a main heating pipe, a main transverse sealing mechanism and a main longitudinal sealing mechanism; and the slave combination roller comprises a slave heating pipe, a slave transverse sealing mechanism and a slave longitudinal sealing mechanism. The sealing device has the beneficial effects of high heat resistance, stable operation, long service life, small material fall and no flying powder. The sealing device can change the bag making length and can replace packaging products through changing relative rotating speed of the main transverse sealing mechanism and the main longitudinal sealing mechanism, so that the operation is simple. The invention further discloses a packing machine; and the packing machine comprises a molding machine and a shearing machine, and further comprises the sealing device.
Description
technical field [0001] The invention relates to a packaging machine, in particular to a sealing device for the packaging machine and a packaging machine containing it. Background technique [0002] In the field of packaging machinery, the composite film vertical small bag packaging machine is divided into a splint type packaging machine and a roller type packaging machine. The roller packaging machine is a small bag packaging machine that continuously rotates and seals without interruption. Because there is no reciprocating motion, it has the characteristics of high production efficiency and low failure rate, and is currently widely used. For example: instant noodle seasoning packs, sachets of shampoo, sachets of tomato sauce, isatidis granules, etc. [0003] Existing Chinese utility model patent, its publication number is: 2567154, and this utility model discloses a kind of sealing device of small bag packaging machine. It is composed of roller support, longitudinal heat-...
