[26] Referring to FIG. 1, an embodiment of the present invention provides a packaging film releasing and conveying device, including a film releasing mechanism 1, a balance tensioning mechanism 2, a film conveying mechanism 3 and a coating guide mechanism 4.
[27] Referring to FIG. 2, the film releasing mechanism 1 is used for fixing a film roll and releasing the film roll 5 to form a released film 6; the film releasing mechanism includes a film releasing motor 11 and an expansion shaft 14; the film releasing motor
11 is connected to a speed reducer 12; an output shaft of the speed reducer 12 passes through a bearing and is connected with the expansion shaft 14; the bearing is arranged in a bearing pedestal 13; the expansion shaft 14 is used for sleeving the film roll 5; the expansion shaft 14 passes through an inner hole of the film roll 5 and tightens the film 5 roll 5; the film roller 5 is replaced by pushing; the expansion shaft 14 is ventilated and expanded after being sleeved with the film roll 5, which increases a friction force between the expansion shaft 14 and the inner hole of the film roll 5 and ensures no slip between the film roll 5 and the expansion shaft 14; the film releasing motor 11 rotates to drive the expansion shaft 14 to rotate, so that the film roll 5 is rotatably released to form the released film 6, thus achieving active film releasing; and the expansion shaft 14 prevents the film roll 5 from slipping to affect the coating effect.
[28] Referring to FIG. 3, the balance tensioning mechanism 2 is arranged on one side of the film releasing mechanism 1. The balance tensioning mechanism 2 includes a vertical rectangular tensioning framework, upper and lower edges of which are fixed shafts 21; the two vertical edges are guide optical axes 22; the two guide optical axes 22 are sleeved with slidable horizontal floating rollers 23; one buffer spring 24 is arranged below two ends of each of the floating rollers 23; the two buffer springs 24 are respectively sleeved on the two guide optical axes 22; an upper end of each buffer spring 24 supports one end of the floating roller 23; one end of each floating roller 23 is provided with a travel switch 25; and the travel switch 25 is connected with the film releasing motor 11 and is used for adjusting a film releasing speed of the film releasing motor 11. In this embodiment, the travel switch 25 is a guide rod linkage travel switch, which is used for determining an upward sliding distance of the floating roller 23 and is inclined relative to the tensioning framework. When the floating roller 23 moves to be close to an upper edge of the tensioning framework, a guide rod of the travel switch 25 contacts the fixed shaft 21 and is stressed to rotate and be triggered.
[29] The released film 6 bypasses a position below the floating roller 23. When the film releasing speed of the film releasing mechanism 1 is less than a film pulling speed at the back, the floating roller 23 will move upward along the guide optical axis 22 under the pulling action of the released film 6, and the floating roller 23 drives the travel switch 25 to move upwards together. When the floating roller 23 rises to be close to the fixed shaft 21 at the upper edge of the tensioning framework, the travel switch 25 is triggered, and the film releasing motor 11 needs to be controlled to rotate to increase the film releasing speed; and after the film releasing speed is greater than the film pulling speed at the back, one cycle of a dynamic balance is completed. The film releasing mechanism 1 can cooperate with the balance tensioning mechanism 2 to make rolling up and releasing of the film roll 5 in the dynamic balance all the time. The tension of the released film 6 here is decided by the gravity of the floating roller 23, so that the tension can be adjusted to the most suitable tension range as required to ensure stable running of the entire device.
