Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art.

The packaging film conveying apparatus 1 according to an embodiment of the present invention is described in detail below with reference to the drawings.

Referring to fig. 1 and 3, a packaging film conveying device 1 according to an embodiment of the present invention is shown. The device is mainly suitable for the package film packaging equipment when the roll film stops after starting, can make the roll film can not stop immediately because of inertia or static, realizes the accurate membrane of putting of package film, realizes the intermittent type nature of packaging equipment and puts the membrane. The packaging film conveying device 1 comprises a frame 11, a film roller 12, a traction part 13 and a film placing part 14.

Specifically, referring to fig. 1, a film roll 12 is disposed on a frame 11, and the film roll 12 is adapted to place a rolled film 2; the drawing member 13 includes a drawing roller group 131 adapted to draw out the packaging film 21 on the roll film 2 and a rotary drive 132 for driving the drawing roller group 131 to rotate; the film placing part 14 comprises a film placing rod 141, a fixed roller set 142 suitable for bearing the packaging film 21 and a proximity switch 143 used for controlling the opening and closing of the rotary driving piece 132, wherein the film placing rod 141 is arranged on the rack 11 in a lifting manner between a first position A for lifting the packaging film 21 and a second position B of a sensing surface of the proximity switch 143; when the film releasing rod 141 is lifted from the first position a to the second position B by the lifting force of the packaging film 21, the proximity switch 143 senses the film releasing rod 141 and controls the rotation of the rotary driving member 132 to convey the packaging film 21; when the film laying lever 141 descends from the second position B to the first position a, the rotation driver 132 stops rotating, and the conveyance of the packaging film 21 stops. It is understood that the film roll 12 may be disposed below the set of draw rolls 131; the film placing rod 141 can be arranged below the fixed roller group 142; before the packaging film 21 is conveyed, the packaging film 21 is pulled out from the roll film 2, passes through the traction roller set 131 to the fixed roller set 142, then passes through the fixed roller set 142, bypasses a part of the peripheral surface of the film releasing rod 141, and then passes out of the fixed roller set 142. Thus, when the packaging film 21 is pulled, the film releasing rod 141 is lifted upwards by the packaging film 21, and when the film releasing rod 141 approaches the sensing surface of the proximity switch 143, the proximity switch 143 is triggered, so that the proximity switch 143 controls the rotary driving member 132 to drive the traction roller set 131 to rotate, thereby driving the packaging film 21 on the roll film 2 to be conveyed; then, when the rotary driving element 132 is running, the speed of the rotary driving element is greater than the rotation speed of the film releasing rod 141, so that the film releasing rod 141 gradually descends to the first position a, the film releasing rod 141 cannot trigger the proximity switch 143, and the proximity switch 143 controls the rotary driving element 132 to stop running, so that the packaging film 21 stops conveying; when the film needs to be continuously placed at the subsequent station, the packaging film 21 is pulled again, the process can be circulated, the accurate film placing of the packaging film packaging equipment is realized, and the intermittent film placing of the packaging equipment is also realized. The pulling of the packaging film 21 may be performed automatically or manually in a subsequent process when the packaging film 21 is needed.

Referring to fig. 2, the drawing roller set 131 includes a rubber drawing roller 1311 and a first roller 1312, the rubber drawing roller 1311 is pivoted on the frame 11, and the first roller 1312 is adjustably disposed on the frame 11 between a position close to the rubber drawing roller 1311 and a position far from the rubber drawing roller 1311. Specifically, both end portions of the rubber traction roller 1311 are pivoted on the frame 11 through ball bearings, and one end portion of the rubber traction roller 1311 extends outward through the frame 11 and is connected to the rotary driving member 132 to be driven to rotate by the rotary driving member 132. The adjustable arrangement of the first idler 1312 can be realized by arranging the first through hole 111 on the frame 11, so that the end of the first idler 1312 is inserted into the first through hole 111 and connected with the adjusting member 133, so as to adjust the position of the first idler 1312 through the adjusting member 133. It is understood that the first through hole 111 may be an elongated hole, and the adjusting member 133 may include a connecting rod 1331, a rotating block 1332 and a spring 1333, where one end of the connecting rod 1331 is fixedly connected to the end of the first supporting roller 1312, the other end is rotatably disposed on the rotating block 1332, the spring 1333 is connected to the first supporting roller 1312 at one end, and the other end is connected to the hole wall of the first through hole 111; when the rotating block 1332 rotates, the position of the first idler 1312 at the first through hole 111 may be varied, and the distance between the first idler 1312 and the rubber traction roller 1311 may be adjusted, so that the traction roller set 131 may grip the packaging film 21 to pull and convey the packaging film 21 in accordance with the rotation of the traction roller set 131. In this embodiment, the rotary driving member 132 may adopt a speed reduction motor structure.

Referring to fig. 1, the fixed roller set 142 includes two fixed rollers 1421 disposed in parallel and at an interval; the film discharging lever 141 is disposed just below the gap between the two fixing rollers 1421. In this way, when the packaging film 21 is pulled from between the rubber pulling roller 1311 and the first idler 1312 to the fixed roller set 142, it can pass through between the fixed roller set 142, pass around a part of the circumferential surface of the film laying rod 141, and then pass out from the fixed roller set 142. In addition, a connecting plate 144 is arranged below the fixed roller 142, and a second through hole 1441 for accommodating the end part of the film placing rod 141 and allowing the film placing rod 141 to move up and down is arranged on the connecting plate 144; it can be understood that the two end portions of the film releasing rod 141 are inserted into the two second through holes 1441 in a one-to-one correspondence manner, and when the packaging film 21 is pulled, the film releasing rod 141 is driven to move up in the second through holes 1441, and when the rotation speed of the rotary driving member 132 is greater than that of the film releasing rod 141, the film releasing rod 141 gradually descends in the second through holes 1441; thus, the conveyance and stop of the packaging film 21 are realized by the up-and-down movement of the film release lever 141 and the engagement of the proximity switch 143 with the rotary drive 132. Further, the proximity switch 143 may be disposed below the second through hole 1441; when the film placing rod 141 is lifted to the second position B, the sensing surface of the proximity switch 143 can be accessed.

In some examples, referring to fig. 1, a second idler 151 and a third idler 152 adapted to pull the packaging film 21 to a next station are further disposed behind the film placing part 14, and the third idler 152 is disposed below the second idler 151; the third supporting roller 152 is arranged between the third position C and the fourth position D in a liftable manner by the lifting force of the packaging film 21. In this embodiment, the two end portions of the third supporting roller 152 are inserted into the two inclined plates 153 in a one-to-one correspondence, and the two inclined plates 153 are respectively provided with a third through hole 1531, so that the third supporting roller 152 can move up and down on the inclined plates 153, and the packaging film can be better connected to the next station. In addition, a photoelectric eye device 154 for detecting a cursor on the packaging film 21 is arranged in front of the second carrier roller 151; so that each of the packaging films 21 for packaging has a cursor. Of course, a coding machine can be arranged on the machine frame to print the production date on the packaging film.
