Since the restraining needle 42 is located in the channel 3411 formed by the first annular gap 341 and the second annular gap 342, the restraining needle 42 is not rolled when the first feeding roller 31 and the second feeding roller 32 rotate.
The limiting needle rod 42 extends out of the channel 3411 from right to left, the left end of the limiting needle rod 42 is provided with an access board 43 (the board is positioned on the left side of the first feeding roller 31 and the second feeding roller 32, and the access board 43 is arranged at intervals with the first feeding roller 31 and the second feeding roller 32), and the left end part of the limiting needle rod 42 is carried on the top of the access board 43.
Meanwhile, the right ends of the stopper needle bars 42 are welded to one needle plate 41 together toward the right (the right ends of the stopper needle bars 42 are welded to the left side wall of the needle plate 41 together), and at the same time, the needle plate 41 is positioned on the right side of the first and second feed rollers 31 and 32, and the needle plate 41 is arranged at an interval from the first and second feed rollers 31 and 32).
The front and rear side walls of the needle plate 41 are welded to the front end frame 11 and the rear end frame 12; the front and rear side walls of the butt strap 43 are welded to the front end frame 11 and the rear end frame 12.
After the materials of the packaging bags are conveyed by the first feed roller 31 and the second feed roller 32, the cutting device 5 on the frame 1 pairs the packaging bags
The specific structure of the cutting device 5 is as follows:
the cutting device 5 is arranged at the left side of the butt strap 43, the cutting device 5 comprises a cutter bar 51, a cutter blade 52 is vertically connected downwards to the cutter bar 51, and the cutter blade 52 is tightly attached to the left side wall of the butt strap 43.
The package cutting device 5 further includes a second driving part driving the cutting device 5 to move up and down. The second driving part includes sliders 511 disposed at front and rear ends of the cutter bar 51; correspondingly, the rear side wall of the front end frame 11 and the front side wall of the rear end frame 12 are both provided with sliding grooves matched with the sliding blocks 511; the sliding block 511 is connected with an air cylinder 53 (the sliding block 511 at the rear end of the cutter bar 51 is connected with the air cylinder 53, and the air cylinder 53 is a conventional telescopic air cylinder disclosed in the prior art).
The working process is as follows:
first, the discharging roller 2 discharges the material, and the discharged packaging bag (as a whole, a long strip shape because it is not cut) is discharged. At this time, the packaging bag passes through the floating-up preventing device 4, and the packaging bag is located below the limit needle rod 42 and is limited by the limit needle rod 42 together (the limit needle rod 42 is located below the first feed roller 31, and the packaging bag passes through below the first feed roller 31 and above the second feed roller 32). The limiting needle bar 42 covers the upper part of the packaging bag.
The packaging bag reaches the roller material conveying device 3, and at the moment, the packaging bag is discharged towards the left under the interaction of the first feeding roller 31 and the second feeding roller 32. The wrapping bag relies on the friction roller power ejection of compact of first feed roller 31 and second feed roller 32 (rely on annular protrusion 34 extrusion wrapping bag on first feed roller 31 and the second feed roller 32), because of the friction down, behind the wrapping bag ejection of compact, floats easily. Because the limiting needle rod 42 penetrates through the channel 3411, namely penetrates between the first feeding roller 31 and the second feeding roller 32, when the first feeding roller 31 and the second feeding roller 32 are subjected to friction roller force to discharge materials, the packaging bags are still covered by the limiting needle rod 42, and the free end of the discharged materials is not easy to float.
When the packaging bag reaches the cutting device 5, the air cylinder 53 drives the cutter bar 51 to move up and down to cut the packaging bag.
The device design has the advantages that:
by adopting the matched feeding mode of the first feeding roller 31 and the second feeding roller 32, the free end of the packaging bag cannot have larger freedom degree (the free end is shorter), and the cutting device 5 can cut neatly. In the process of feeding the packaging bags by the first feeding roller 31 and the second feeding roller, the limiting needle rod 42 is designed, and the limiting needle rod 42 penetrates through the channel 3411, namely, the first feeding roller 31 and the second feeding roller 32, so that the packaging bags are still covered by the limiting needle rod 42 in the process of roller-driven feeding, and the free end of discharging is not easy to float. Meanwhile, the packaging bag can not deviate under the friction force (the packaging bag is composed of two layers, namely the top layer and the bottom layer can not be dislocated under the rolling friction force).
The above description is only exemplary of the present invention and should not be taken as limiting the scope of the present invention, as any modifications, equivalents, improvements and the like made within the spirit and principles of the present invention are intended to be included within the scope of the present invention.
