Abstract
The utility model provides a plastic bag packagine machine's air knife structure, this structure can guarantee to blow open the plastics sack. The air knife comprises a strip-shaped air knife block, wherein a first air cavity is arranged in the air knife block, a first air inlet of the first air cavity is formed in one side of the air knife block, and a first air outlet of the first air cavity is formed in the bottom end of the air knife block and is a strip-shaped narrow slit; the point blowing pipe is close to the middle position of one side of the strip-shaped narrow slit and arranged at the bottom end of the air knife block; one end of the point blowing pipe points downwards, one end of the point blowing pipe is communicated with the second air cavity, the second air cavity is arranged in the air knife block, and a second air inlet of the second air cavity is arranged on one side of the air knife block.
Description
Technical Field
The utility model relates to a plastic bag packagine machine technical field, concretely relates to plastic bag packagine machine's air knife structure.
Background
An air knife of an existing plastic bag packaging machine is mainly characterized in that an air cavity is formed in a long strip-shaped air knife block, an air inlet of the air cavity is connected with an air inlet system, and an air outlet of the air cavity is formed in the bottom end of the air knife block and is a long strip-shaped narrow slit. The compressed air is blown to the plastic bag opening from the air outlet to blow the plastic bag opening. However, in the mode of uniformly blowing air to the plastic bag opening, because the stress of the plastic bag opening is uniform, once the bag opening is not blown out of a gap at the beginning, the bag opening can not be blown out by continuously blowing air at the back, and therefore, the design of the novel air knife is considered, and the plastic bag opening can be conveniently blown out.
SUMMERY OF THE UTILITY MODEL
There is the shortcoming that probably can't blow the plastics sack to current plastic bag packagine machine's air knife, the utility model provides a plastic bag packagine machine's air knife structure, this structure can guarantee to blow the plastics sack open.
The utility model provides a following technical scheme:
the utility model provides a plastic bag packagine machine's air knife structure, its includes rectangular form air knife piece, be provided with first wind chamber in the air knife piece, the first air intake in first wind chamber set up in air knife piece one side, the first air outlet in first wind chamber set up in air knife piece bottom is rectangular form slot, its characterized in that: the point blowing pipe is close to the middle position of one side of the long-strip-shaped narrow slit and arranged at the bottom end of the air knife block; one end of the point blowing pipe points downwards, one end of the point blowing pipe is communicated with a second air cavity, the second air cavity is arranged in the air knife block, and a second air inlet of the second air cavity is arranged on one side of the air knife block.
Compared with the prior art, the beneficial effects of the utility model are as follows:
the utility model discloses a design of some blowpipes, earlier concentrate the application of force through some blowpipes and blow off the clearance with the plastics sack, the first air outlet of rethread evenly blows to whole plastics sack, has guaranteed to blow off the plastics sack.
Drawings
FIG. 1 is a front view of the present invention;
fig. 2 is a schematic bottom view of the present invention;
in the figure: 1, a wind knife block; 2 a first air cavity; 3, a first air inlet; 4, a first air outlet; blowing a pipe at 5 points; 6 a second air cavity; 7 second air inlet.
Detailed Description
The technical solution of the present invention will be described clearly and completely with reference to the accompanying drawings, and obviously, the described embodiments are only some embodiments, not all embodiments of the present invention. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
Referring to fig. 1-2, an air knife structure of a plastic bag packaging machine comprises a strip-shaped air knife block 1, a first air chamber 2 is arranged in the air knife block 1, a first air inlet 3 of the first air chamber 2 is arranged at one side of the air knife block 1, a first air outlet 4 of the first air chamber 2 is arranged at the bottom end of the air knife block 1 and is a strip-shaped narrow slit, and the air knife structure further comprises a spot-blowing pipe 5, wherein the spot-blowing pipe 5 is arranged at the bottom end of the air knife block 1 and is close to the middle position of one side of the strip-shaped narrow slit; one end of the point blowing pipe 5 points downwards, one end of the point blowing pipe is communicated with the second air cavity 6, the second air cavity 6 is arranged in the air knife block 1, and a second air inlet 7 of the second air cavity 6 is arranged on one side of the air knife block 1. The utility model discloses a design of point blowpipe 5 concentrates the application of force through point blowpipe 5 earlier and blows off the clearance with the plastics sack, and the rethread first air outlet 4 has guaranteed to blow off the plastics sack to whole plastics sack evenly.
Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
