Description

Technical Field

[0001] The invention relates to a follow-up bagging device and method for packaging equipment, and in particular to a full-automatic bagging device and method for a paper product packaging machine. Background Art

[0002] Packaging machines are equipment that packages products and are widely used in industrial production. For the packaging of products produced on assembly lines, such as paper product packaging, the degree of automation of the packaging machine is required to be high. For paper product packaging machinery and equipment, how to open the packaging bag and push the material in is currently a major technical problem. Currently, most people use manual methods to put the packaging bag on the bag-supporting duckbill and open the duckbill to open the packaging bag. The efficiency of manual bagging is extremely low and it is difficult to meet production requirements. Some packaging equipment with a high degree of automation mostly use complex and large bag suction and bagging mechanisms to achieve automatic bagging. The mechanism is complex and the cost is very high. In addition, due to the various specifications of packaging bags, the bag suction width of the suction straw of the bag suction mechanism must correspond to the width of the packaging bag. The corresponding specifications must be adjusted before sucking the bag, which further complicates its structure and affects production efficiency. Summary of the invention

[0003] The purpose of the present invention is to overcome the shortcomings of the prior art and provide a follow-up bagging device and method for packaging equipment, creatively designing an automatic bag suction and bagging device that follows the duckbill mechanism, which has a simple structure, low cost, and high bagging accuracy and success rate.

The two opening and closing guiding rails follow the change of the width adjustment of the duckbill mechanism of the packaging device; the telescopic power mechanism is connected to the two opening and closing guiding rails, and the telescopic power mechanism controls the two opening and closing guiding rails to extend or retract from the duckbill mechanism; there are guiding tracks on the telescopic guiding track plates, and the four telescopic guiding track plates are respectively fixed on the upper left duckbill mechanism, the lower left duckbill mechanism, the upper right duckbill mechanism, and the lower right duckbill mechanism of the packaging device. The four telescopic guiding track plates follow the change of the height adjustment and width adjustment of the duckbill mechanism of the packaging device; the four straws, two straws are fixed on one opening and closing guiding rail through sliders, and the other two straws are fixed on the other opening and closing guiding rail through sliders. At the same time, the four straws are respectively connected to the guiding tracks of the four telescopic guiding track plates through bearings. The telescopic power mechanism controls the four straws to extend or retract from the duckbill mechanism through the two opening and closing guiding rails. The opening and closing of the duckbill mechanism controls the left and right straws to slide and open and close on the two opening and closing guiding rails. During the extension or retraction of the four straws, they are guided to close or open through the guiding tracks of the four telescopic guiding track plates.

[0005] A follow-up bag-sleeving method for a packaging device, using the device described above, is characterized in that: the straws for bag-sleeving of the packaging device are connected to the duckbill mechanism in a follow-up manner. The bag-sleeving width and bag-sleeving height of the straws are adjusted in a follow-up manner through the bag-supporting width and bag-supporting height of the duckbill. Through the control of the duckbill mechanism and the telescopic power mechanism and under the guiding action of the opening and closing guiding rails and the telescopic guiding track plates, a series of actions of extending, biting, sucking the bag, retracting, and bag-sleeving are completed, including the following steps.

[0006] a. The duckbill mechanism controls the four straws to reach the bag-sleeving width.

[0007] b. The telescopic power mechanism controls the two opening and closing guiding rails to extend from the duckbill mechanism. The four straws are driven by the two opening and closing guiding rails to extend from the duckbill mechanism. At the same time, under the guiding of the guiding tracks of the four telescopic guiding track plates, the upper and lower straws on the left and the upper and lower straws on the right are closed to bite the packaging bag.

[0008] c. After the straws suck the packaging bag, the telescopic power mechanism controls the two opening and closing guiding rails to retract. The four straws are driven by the two opening and closing guiding rails to retract into the duckbill mechanism. At the same time, under the guiding of the guiding tracks of the four telescopic guiding track plates, the upper and lower straws on the left and the upper and lower straws on the right are opened, and the packaging bag is sleeved on the duckbill of the duckbill mechanism to complete the bag-sleeving action.

[0009] d. The duckbill mechanism controls the duckbill to open the packaging bag to complete the bag opening.

[0010] The beneficial effects of the present invention are as follows.
