AI Technical Summary

Problems solved by technology

The existing problems are: first, the handle of the packaging bag is irregular, and the reference document 1 inserts the packaging bag into the U-shaped transmission clip through the plug-in plate of the plug-in device, because the U-shaped transmission clip is Can not be opened and closed, its space is fixed
The problem in Comparative Document 2 is that the disclosed plastic bag feeding mechanism consists of two parts: the product conveying manipulator and the product output clamp. In fact, one set of manipulators is turned upside down from another manipulator and then inserted into the rubber band stretching device. Yes, this kind of "reverse hand" is not only complicated in structure, but also easy to grasp and deform the folded packaging bag when you get it
[0006] No matter it is comparative document 2 or comparative document 3, a common problem is that during the strapping process, the product conveying manipulator or clamping device can only clamp one side of the packaging bag, and about half of the other side of the packaging bag is on the outside of the manipulator or splint
And if the rubber band is stretched too much, it will be easily broken, and the damage rate of the rubber band is high.
In this case, a larger type of rubber band is required, which increases the cost of binding
And the bundled bags are uneven and irregular

Embodiment 1

[0040] Embodiment 1, the handle folding device 12 of Embodiment 1 is mainly composed of a front corner folding mechanism, a trapezoidal front folding plate mechanism, a bag-pressing hook mechanism, a pressing plate mechanism, etc.; the tail folding device 14 is mainly composed of a rear folding plate and a Swing cylinder etc. constitute; Described flashboard device 13 mainly is made of flashboard, flashboard cylinder, guide rod. Please refer to reference document 1 for the handle folding device 12, insert plate device 13 and tail folding device 14; for the vibrating plate device 11 and rubber band stretching device 7, please refer to reference document 2 or reference document 3 for specific implementation.

[0041] like figure 1 , figure 2 As shown in the figure: install the board opening device 13 above the frame 1 , and install the handle folding device 12 and the tail folding device 14 below the board board device 13 . A flat supporting plate 4 is respectively installed ...

Embodiment 2

[0043] Embodiment 2, the main difference between embodiment 2 and embodiment 1 is that the handle folding device of embodiment 2 is a plastic bag head folding device composed of an adjustable supporting plate mechanism, a U-shaped pushing and folding plate mechanism, etc. The device can be specifically implemented with reference to the comparison document whose publication number is CN109264120A or CN208361926U; as Figure 11 , Figure 12 , Figure 13 As shown, the telescopic drive mechanism includes a guide rail 34, a slide block 35, and a cylinder 33;

[0044] like Figure 11 , 12 , shown in 13: two hollow splints 21 are set, a slide block 35 is respectively installed on the outsides of the two splints 21, and a guide rail 34 is respectively installed on the outsides of the two expansion plates 31, so that the outsides of the two expansion plates 31 are respectively Slidingly installed on the slide block 35; connect the cylinder 33 on the telescopic plate 31, when the cyli...

Embodiment 3

[0046] Embodiment three, the main difference of embodiment three lies in: as Figure 19 As shown, the splint moving mechanism is a swing device, including a rotating shaft 29, a rocker arm 28, and a cylinder 27. The clamping plate mechanism that clamping plate 21, telescopic plate mechanism 3, clamping cylinder 23 constitute is installed on the rotating shaft 29, the two ends of rotating shaft 29 are rotated and installed on the frame, rocking arm 28 is installed at one end of rotating shaft 29, and rocking arm 28 A cylinder 27 is installed on the top.

[0047] The main working process of the third embodiment is as follows: when the packaging bag 8 is inserted between the two splints 21 and the two telescopic plates 31, after the insertion plate device 13 is lifted, the clamping cylinder 23 is opened to drive the two splints 21 to wrap the packaging bag 8 clamped, formed as Figure 19 status shown. Afterwards, the cylinder 27 opens the drive rocker arm 27 to make the rotati...

Abstract

The invention discloses a folding and binding machine of a packaging bag. The folding and binding machine comprises a machine frame, a vibration disc device, a rubber band expanding device, a liftinghandle folding device and a plate inserting device, and is characterized in that a conveying clamping plate device is arranged below the plate inserting device, a telescopic plate mechanism is furtherarranged on clamp plates, and a follow-up movement mechanism is further arranged on the machine frame. The packaging bag is clamped to form a folded state after being inserted into the two clamp plates and a telescopic plate by the plate inserting device, then the telescopic plate gradually retracts towards the direction of the clamp plates, so that one side of the packaging bag is gradually exposed out of the telescopic plate, the rubber band expanding device is driven by the follow-up movement mechanism to follow up along with the retraction of the telescopic plate, and the packaging bag isinserted into the expanded rubber band. The problem that one side of the packaging bag rebounds and opens due to the lack of clamping of mechanical arms and is difficult to insert into the rubber band is solved.

Description

technical field [0001] The invention relates to a folding and binding machine for packaging bags, in particular to an integrated device which firstly automatically folds the packaging bags, and then automatically binds the folded packaging bags by using ring-shaped rubber bands. Background technique [0002] The packaging bag of the present invention is a plastic packaging bag with two handles, also called convenience bag, vest bag, shopping bag, etc. The packaging bags automatically produced by the bag making machine are generally dozens of them neatly stacked together. In order to facilitate storage, sales and use, these packaging bags need to be folded many times. First, the two handles of the packaging bag need to be folded, and then folded several times according to the length of the packaging bag or market demand, and finally folded into strips shape, and then bind it with a ring-shaped rubber band in the middle of the long strip bag. The so-called bundling is to spr...
