[0001] The utility model relates to the technical field of corrugated paper production equipment, in particular to a high-speed and precise corrugated paper box creasing film cutting machine. Background Art
[0002] Corrugated paper boxes are the most widely used packaging products, and their usage has always been the first among all kinds of packaging products. With its superior performance and good processing performance, corrugated paper boxes have gradually replaced wooden boxes and other transport packaging containers and become the main force of transport packaging. In addition to protecting goods and facilitating storage and transportation, they also play a role in beautifying and promoting goods. Corrugated paper boxes are green and environmentally friendly products, which are beneficial to the environment and convenient for loading and unloading.
[0003] Film cutting machines are needed in the production process of corrugated boxes. Today's film cutting machines generally use continuous paper feeding. As the paper feeding speed increases, the paper will have a greater impact when it approaches the front gauge, which can easily cause the paper to bounce or curl, resulting in inaccurate positioning and reduced precision, which has a certain impact on people's interests.

A fixing rod is arranged between the two connecting plates and above the second hydraulic cylinder and the third hydraulic cylinder. A sliding plate is fixedly arranged on the upper end surfaces of the second hydraulic cylinder and the third hydraulic cylinder. A sliding through hole is opened through the sliding plate, and the sliding through hole is horizontally opened on the sliding plate. The sliding plate is slidably matched with the fixing rod through the sliding through hole, and a fixing device for fixing or releasing the sliding plate from the fixing rod is arranged between the upper end of the sliding plate and the fixing rod.
[0009] A further improvement is that the fixing device includes a plurality of positioning slots which are equidistantly arranged laterally on the upper end surface of the fixing rod, connecting holes which penetrate the upper ends of the two sliding plates and are connected with the sliding holes, a positioning rod which can be lifted and lowered on the sliding plate and is located in the connecting holes and is used to engage with the positioning slots, and a driving member which is arranged between the upper end of the positioning rod and the upper end of the sliding plate and is used to drive the positioning rod to engage or disengage with the positioning slots, and the connecting holes are longitudinally arranged on the sliding plate.
[0010] A further improvement is that the driving member includes a driving plate arranged on the upper end surface of the positioning rod, two tension springs arranged between the lower end surface of the driving plate and the upper end surface of the sliding plate and located on the left and right sides of the positioning rod, a lifting ring arranged at the upper end of the driving plate for allowing the driving plate to be pulled up by hand, and a limiting member arranged between the upper end surface of the sliding plate and the lifting ring for cooperating with the lifting ring after the lifting ring is pulled up to limit the descent of the driving plate.
[0011] A further improvement is that the limiting member includes a longitudinal plate longitudinally fixedly arranged on the upper end of the sliding plate, and a limiting rod slidably arranged on the longitudinal plate.
