Description

Technical Field

[0001] The present invention belongs to the technical field of packaging equipment, and specifically relates to an intelligent high-speed roof bag filling machine with a high degree of automation, which can ensure the regularity of packaging paper box forming, facilitate the smooth flow and uniform distribution of coolant in a sealing core mold, and has a fast capping operation speed of a capping mechanism, accurate capping of the box cover, and strong connection stability. It can realize high-speed operation of production equipment, stable and reliable operation, effectively improve production efficiency, low failure rate, high sanitation level, ensure product quality, and strong applicability. Background Art

[0002] The existing packaging carton suction box mechanism of the roof bag filling equipment, in the process of sucking the stretched packaging carton and pushing the carton onto the carton core mold of the rotating indexing seat, must wait for the pushing component to push the carton and return completely before the next carton suction action can be performed. The suction box mechanism of this traditional structure needs to perform each step-by-step action in sequence, which has low work efficiency and hinders the improvement of the speed of subsequent packaging carton lidding, filling and other processes. At the same time, the existing packaging carton bottom making operation is to use the bottom sealing mechanism to heat and seal the packaging carton set on the sealing core mold one by one. However, the core mold rotating mechanism currently used has a complex structure, a high failure rate and poor practicality; and the coolant delivery pipeline often interferes with the transmission mechanism, affecting the stable rotation of the sealing core mold and hindering the high-speed operation of the production equipment. The coolant delivery structure of the existing sealing core mold rotating mechanism is not conducive to the smooth flow of the coolant, and the distribution of the coolant in each sealing core mold is uneven, and the cooling effect is not ideal.

[0003] In addition, the capping process of the paper box cover on the existing packaging paper box is mostly done manually, which not only has low work efficiency and poor connection stability of the box cover, but also has uneven appearance quality of the product and low product hygiene level. In addition, some existing automatic capping devices have complex structures and large volumes, low capping accuracy, and high operating failure rates; and in the process of automatic capping operations, the welding base and the packaging paper box in the conveying process often interfere with each other, so the action speed of the capping mechanism cannot be too fast, which hinders the further improvement of the capping speed and low production efficiency. At the same time, the filling and lifting mechanism of the existing cam transmission structure is not only large in size and occupies a lot of space, but also has a slow lifting and lowering speed, poor operating stability, a high failure rate, and insufficient adaptability. Therefore, it is necessary to improve the roof bag filling equipment of the prior art. Summary of the invention
