Problems solved by technology

[0007] The problems caused by the front and rear misalignment of the packaging bag are: first, if Figure 9 As shown, if the packaging bags A, B, and C on the storage bag tray 7 are dislocated in a "step" shape from top to bottom and retracted one by one, then when the suction nozzle 20 of the suction plate is picking up the bag, due to the uppermost The packaging bag A is retracted for a section that cannot correspond to the top and bottom of the suction nozzle 20, and the suction nozzle 20 will suck into the packaging bag B or C that protrudes backward in the storage bag tray through the packaging bag A, instead of the top packaging Bag A
The single suction point of the suction plate in the prior art is set regardless of the past and the future, and the reliability of the bag taking work and the opening work is difficult to guarantee

Embodiment 1

[0033] Example 1, such as figure 1 , figure 2 , image 3 , Figure 4 , Figure 5 As shown (the left side among the accompanying drawings is described as the front in this specification), a suction plate 2 is set, and a cavity is set at a position corresponding up and down with the bag opening suction nozzle 6 of the opening device in the middle of the front part of the suction plate 2, in the cavity A filter screen is inlaid on the cavity or a dense air hole is set to form a bag opening suction nozzle 24; The suction plate 2 is installed on the suction plate rotating shaft 21, the two ends of the suction plate rotating shaft 21 are respectively provided with rotating shaft hollows 22, 23, and one side of the suction plate rotating shaft 21 is respectively drilled to communicate with the rotating shaft hollows 22, 23, and the pipeline 26 Make the cavity of the bag-taking suction nozzle 25 communicate with the rotating shaft hollow 22; make the cavity of the bag-opening su...

Embodiment 2

[0034] Embodiment 2: The difference between embodiment 2 and embodiment 1 is that the suction nozzle for opening the bag and the suction nozzle for taking the bag are a kind of suction cup, and the suction cup for opening the bag 28 and the suction cup for taking the bag 29 are respectively installed on the suction plate 2 front and back, respectively. The shaft hollows 22, 23 at the two ends of the suction plate shaft 21 are connected by the pipelines 26, 27; the hollow shafts 22, 23 are connected by two suction fans 3 and 31 respectively, and the fluid valve 32 is omitted, as Image 6 shown.

[0035] The specific working process is as follows: when the swing device 5 drives the suction plate 2 to swing backward to the top of the bag storage tray 7, the fluid valve 32 or the suction fan 30 are closed, and the bag opening suction nozzle 24 has no suction; the suction fan 3 is Opened, the high-speed rotation of suction fan 3 makes the area of ​​bag suction nozzle 25 or bag suct...

Abstract

The invention discloses a swinging type bag fetching opening device of a packaging machine and a control method. The swinging type bag fetching opening device comprises a machine frame, a suction plate, an air suction fan, a swinging device, an opening mechanism and a bag storage disc, and is characterized in that a bag opening suction nozzle and a bag fetching suction nozzle are arranged at the front part of the suction plate; the bag fetching suction nozzle is arranged behind the bag opening suction nozzle; the bag opening suction nozzle and the bag fetching suction nozzle are respectively connected with the air suction fan through air suction passages, and are independently controlled. The control method is characterized in that when the suction plate is swung onto the bag storage disc and is close to a packaging bag, the bag opening suction nozzle is closed, and the bag fetching suction nozzle is opened; when the first packaging bag on the bag storage disc is fetched out, the bag opening suction nozzle is opened to suck the lower layer of the packaging bag, and the bag opening suction nozzle is moved downwards to suck the upper layer of the packaging bag and lift up, so as to realize the opening function; the bag opening suction nozzle and the bag fetching suction nozzle are arranged in the front and back parts and are independently controlled, so the defect of fetching of multiple packaging bags at one time in the bag fetching process is overcome, and the opening of the packaging bag is easy.

Description

technical field [0001] The invention relates to a packaging machine, in particular to a swing-type bag taking and opening device and a control method for the packaging machine. Background technique [0002] A swing-type bag taking and opening device and control method, which are applied to a packaging machine, take out the packaging bags in the bag storage tray one by one and place them at a predetermined working position, and open the opening of the packaging bags, so that the two close-up of the packaging machine The supporting plate mechanism stretches in from this smaller opening and further expands the bag opening, so that the packing material can be filled into the packing bag. [0003] Application publication number CN104150023A, publication date: November 19, 2014, discloses a plastic bag packaging machine, application publication number CN104290965A, publication date: January 21, 2015, discloses a swing type bag taking opening device and The bag method. The two pa...
