Problems solved by technology

The problem is: first, after the manipulator grabs the rubber band, the rubber band will sag, and the sagging of the rubber band will cause the inner diameter of the originally round rubber band to become elliptical, which is not conducive to the simultaneous insertion of four struts. The success rate is small, which seriously affects the working stability of the machine; the second is that the rubber band is easy to shake and shake during the process of being grasped and transferred by the manipulator, and it takes a long time to stabilize
The existing problem is that when the two pins of the horizontal stretching mechanism stretch the rubber band horizontally, the length of the circumference of the rubber band will be equally divided into upper and lower sections at the positions of the two pins, because the rubber band has a higher Elasticity, when the relative position of the two pins remains unchanged, when the upper rubber band (two pins) is tightened or pulled, only the upper rubber band can be tightened, while the lower rubber band Because the resistance of the two pins cannot be tightened, this phenomenon is generally called "not walking the rope".
When the two supporting rubber bands described in the comparative document 4 hold up the upper part of the rubber band upwards, although a trapezoid can be formed to be placed on the plastic bag, it can only tighten the upper part of the two pins. This makes the lower part of the rubber band looser and the upper part of the rubber band is too tight and easy to break
That is to say: the stretching and transposition of the rubber band in the comparative document 4 includes a horizontal stretching mechanism and a vertical stretching mechanism. The two rubber bands clamping your hands can only stretch the upper part of your rubber band, the lower part of the rubber band cannot be stretched tightly, but the upper part of the rubber band is easy to break if it is too tight, and it is precisely because of this way of supporting the elastic The degree is different, so it is difficult for this strapping machine to adapt to the market

Embodiment 2

[0048] Embodiment two, such as Figure 12 As shown: the main difference between the second embodiment and the first embodiment is: one is that one side of the bracket 40 is hinged on the frame 1, and the insertion movement mechanism is a swing cylinder 55; Mechanism 9 is installed on the plastic bag conveying device 3, and rib removal mechanism 9 is a kind of rib removal bar 91, and rib removal bar 91 is installed on the both sides of mechanical clamp 34, and two side positions of each side are respectively installed two rib removal bars. The rib bar 91 makes the space enclosed by the 4 rib bars 91 larger than the width of the struts 43 on both sides after being stretched; a hinged column 54 is installed on one side of the support 40 so that the support 40 passes through the hinged column 54 is hinged on the frame 1, and a swing cylinder 55 is installed on the hinge column 54 and the bracket of the frame 1, the vibration plate device 2 is installed on the front right side of t...

Embodiment 3

[0050] Embodiment three, the main difference of embodiment three is: as Figure 14 As shown, the U-shaped notch 21 is arranged obliquely; the bottom side support bar 42 is fixedly arranged on the bottom side of the bracket 40, corresponding to the bottom of the U-shaped notch 21; Side strut 41; a two-side strut 43 is installed at a position corresponding to the upper side strut 41 directly below, so that the two-side strut 43 corresponds to the bottom side strut 42 left and right, and also corresponds to the upper side strut 41 Corresponding up and down, so that a right-angled triangle is formed between the two side struts 43, the bottom side struts 42, and the upper side struts 41; The upper position of the upper side, and corresponding to the upper side strut 41 left and right, the two side struts 43, the upper side strut 41 are respectively connected with the strut cylinder 44, and the strut cylinder 44 is installed on the support 40 respectively.

Abstract

The invention discloses a plastic bag strapping machine. The plastic bag strapping machine comprises a machine frame, a vibration disc device and a plastic bag conveying device. The plastic bag strapping machine is characterized in that a U-shaped notch is arranged on the vibration disc device; a rubber band expansion device is arranged at the position corresponding to the U-shaped notch; the rubber band expansion device comprises a bracket; the bracket is provided with an upper side supporting rod, a bottom side supporting rod, two side supporting rods and an expansion cylinder; an insertionmoving mechanism is connected between the bracket and the machine frame; and the plurality of supporting rods penetrate through the U-shaped notch to be inserted into an inner hole of a rubber band under driving of the insertion moving mechanism, so that the rubber band is expanded in one direction and taken out from the U-shaped notch after being narrowed, and then stretched again. Compared withthe prior art, the plastic bag strapping machine omits a rubber band transfer mechanism and a driving device thereof, so that the whole machine is compact in structure, the working procedure is simplified, and the grasping and expansion work of the rubber band is reliable and stable.
