Description

Technical Field

[0001] The invention belongs to the technical field of automated production equipment, and in particular relates to a fool-proof automated box sealing production line and its workflow. Background Art

[0002] With the development of society, packaging and sealing machines play an increasingly important role in various machines. Packaging is a necessary condition for products to enter the circulation field, and the main means of achieving packaging is to use packaging machinery. At the same time, with the development of the times and the advancement of technology, packaging and sealing machinery plays an increasingly important role in the circulation field. With the continuous development of science and technology and the emergence of various food processing products, new requirements have been put forward for packaging technology and packaging equipment. The packaging box sealing machine is an indispensable part of packaging machinery. It mainly uses tape to seal the carton. The sealing size can be adjusted according to the size of the carton. The sealing is flat and the upper and lower sealing actions can be completed at one time. It can be operated as a single machine or used in conjunction with an assembly line. It is widely used in household appliances, textiles, department stores, medicine and other industries.

[0003] At present, the competition in packaging box sealing machinery is becoming increasingly fierce. In the future, packaging box sealing machinery will cooperate with the trend of industrial automation, promote the overall level of packaging equipment, and develop multifunctional, high-efficiency, and low-consumption packaging equipment. The packaging box sealing machinery technology is also developing towards the following trends: mechatronics, diversification of mechanical functions, standardization of structural design, intelligent control, and high-precision structural movement.

[0004] In the prior art, for example, the carton sealing machine with application number 201710832458.7 is a hydraulic cylinder that drives the rear push plate to move, and forms a clamping mechanism with the front fixed baffle, so that the front and rear cardboards are closed and folded. The distance between the two guide plates can be flexibly adjusted according to the width of the standard carton. According to the height of the box, the electric telescopic mechanism can drive the slide plate to move up and down to achieve the change of the corresponding lowest point of the front fixed baffle. The two bending rods are used to achieve the closing and folding of the left and right cardboards during the movement of the box. The carton is sealed with tape, and the sealing size can be adjusted at will according to the size of the carton. The sealing is flat, and the upper and lower sealing actions can be completed at one time. It can be operated as a single machine or used in conjunction with an assembly line. It is widely used in household appliances, textiles, department stores, medicine and other industries. However, in automated production, the number of workers is small. If the tape of the carton sealing machine is used up during the production process, it is generally not easy to detect, resulting in the packaging boxes that are not sealed by the tape flowing into the next process, causing rework, and some are even shipped directly to customers, causing customer complaints, which has an adverse impact on the development of the enterprise.

[0005] In summary, the relevant technology has defects and needs to be improved urgently. Summary of the invention
