Description

Technical Field

[0001] The invention relates to the technical field of packaging equipment, and in particular to an integrated bag supplying machine. Background Art

[0002] With the continuous advancement of modern production technology and the increasing market demand, the status and role of packaging machinery in the production line are becoming more and more important. The packaging and bagging production line is mainly used to seal and package products. It is widely used in food, medicine, chemical and other industries. It is necessary to fill a certain amount of products into the packaging bag and seal it. The traditional packaging and bagging production line is generally designed with packaging bag loading, conveyor belt, filling, sealing and other stations in the order of work. In factories with low automation or factories with small production line investment, the automation level is low, and manual labor is often interspersed between equipment and equipment stations. It is responsible for opening, pulling, and picking up packaging bags. Generally, multiple robotic arms are required to cooperate to complete the action, which can reduce the investment in production line equipment. Although this type of packaging and bagging production line has achieved a certain degree of automation and has a good balance in production line cost investment, its production line design still has many shortcomings, and it is difficult to meet the high efficiency and high quality requirements of modern production lines.

[0003] First, the efficiency of the packaging and bagging production line is low. Because there are manual workstations between the equipment and the equipment stations, the production line is not fully automated from loading, product filling to sealing and unloading. And because the work flow between the stations is carried out in sequence, it means that the subsequent stations cannot start working before each station completes its task. Once the efficiency of the previous station decreases, especially the manual station will reduce efficiency significantly due to fatigue after working for a long time, the efficiency of the subsequent equipment will also decrease with the number and interval of the products flowing in. This serial working mode leads to a long time for the entire packaging process, and it is difficult to significantly improve the production efficiency and meet the needs of high-volume production. In addition, the operation frequency of a single station is high, which is prone to equipment fatigue, resulting in an increase in the failure rate, which in turn affects the continuity and stability of production.

[0004] Secondly, the packaging and bagging production line occupies a large area. Since each workstation is set up independently, a certain distance needs to be reserved between the equipment, which leads to a long length of the entire production line and occupies more production space. For some small and medium-sized enterprises, the efficiency of production space utilization directly affects the level of production costs. Therefore, the lack of space utilization of the packaging and bagging production line is also one of its main disadvantages.

[0005] Thirdly, the degree of automation of the packaging and bagging production line is relatively low. Although it has realized the automatic loading, opening, filling and sealing functions of the packaging bags, the coordination between the workstations still relies on manual intervention. This not only increases labor costs, but also reduces the stability and consistency of production to a certain extent. Especially when processing packaging bags of different specifications and types, traditional equipment requires complex adjustments and cannot flexibly respond to diverse production needs.

[0006] In summary, the applicant has found that the prior art has at least the following technical problems:

[0007] With the upgrading of the industry, industry manufacturers are in urgent need of upgrading their production capacity, and therefore require more efficient packaging and bagging production lines / equipment; however, the existing packaging and bagging production lines have problems with low automation and production efficiency due to equipment constraints.

Especially when processing sealed bags of different specifications and types, the present invention can be adjusted to meet different packaging needs and flexibly respond to diverse production tasks. The quantitative filling of the filling station and the shaking function of the bag shaking part of the bottom bag opening station ensure the uniform distribution of the product material in the sealed bag and improve the packaging quality. In addition, the heated sealing of the bag sealing station ensures the sealing effect of the sealed bag and avoids product leakage and contamination.

Each station adopts a modular design, which makes the equipment more convenient for function expansion and maintenance. Users can adjust and upgrade the equipment accordingly according to actual production needs to adapt the equipment to industrial upgrading. At the same time, the modular design also simplifies the repair and maintenance process of the equipment and reduces maintenance costs.

[0047] In summary, the integrated bag supply machine of the present invention significantly improves packaging efficiency, product quality and production space utilization through its efficient, compact and automated design, reduces labor costs and equipment maintenance costs, and has broad application prospects and significant economic benefits.
