Description

Technical Field

[0001] This utility model belongs to the field of winding technology, specifically relating to the winding of films, and more particularly to a film splicing device and a film splicing mechanism. Background Technology

[0002] After production, the film needs to be wound up using a winding core.

[0003] Once a core is fully wound up, an empty core needs to be replaced for winding. At this point, the film needs to be cut and pasted onto the empty core.

[0004] In related technologies, during the winding process, a pressure roller is used to first adhere the film to the empty core, and then a cutter is used to cut the film. At this time, excess film will exceed the adhesion position, thus failing to lay flat on the core. This results in defects such as film surface imprints and wrinkles in the initially wound film during the subsequent winding process, making the film's flatness substandard.

[0005] Therefore, how to solve the above problems is a problem that urgently needs to be solved by those skilled in the art.

[0006] It should be noted that the information disclosed in this background section is only for understanding the background technology of the present application concept, and therefore, the above description is not considered to constitute prior art information. Utility Model Content

[0026] The following detailed description, with reference to the accompanying drawings, describes some embodiments of the present invention. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0027] like Figure 1 , Figure 2As shown, at least one embodiment provides a film splicing device, including: a rotating frame 1 on which a plurality of take-up cores 11 are disposed, adapted to move the empty take-up cores 11 to the take-up position by rotation after the film is wound; a splicing mechanism 2, including: a pair of first swing arms 21, a cylinder 22 disposed on the first swing arms 21, a mounting plate 23 disposed on the drive end of the cylinder 22, and a second swing arm 24 disposed on the mounting plate 23; wherein a cutter 25 is disposed between the two mounting plates 23, and a splicing pressure roller 26 is disposed between the two second swing arms 24; the first swing arms 21 are adapted to press the film onto the empty take-up cores 11 by rotation; the second swing arms 24 cooperate with the cylinder 22 to drive the splicing pressure roller 26 to revolve around the take-up cores 11 to adhere the cut film to the take-up cores 11.

[0028] Specifically, the take-up core 11 is driven by the driver to rotate for take-up; the second swing arm 24 is used to drive the receiving pressure roller 26 to rotate upward, and the cylinder 22 is used to drive the receiving pressure roller 26 on the mounting plate 23 to move to the right. That is, the second swing arm 24 and the cylinder 22 cooperate to drive the receiving pressure roller 26 to revolve around the take-up core 11.

[0029] In this embodiment, by setting up the winding mechanism 2, the winding pressure roller 26 of the winding mechanism 2 presses the film onto the take-up core 11 whose surface is coated with adhesive. Then, the cutter 25 cuts the film between the empty take-up core 11 and the full take-up core 11. Finally, through the joint cooperation of the second swing arm 24 and the cylinder 22, the winding pressure roller 26 revolves around the take-up core 11, thereby attaching the excess film to the take-up core 11 and preventing the excess film from folding or wrinkling.

[0030] like Figure 1 As shown, in some embodiments, a tensioning roller 27 is provided between the two mounting plates 23; wherein the first swing arm 21 is adapted to rotate to bring the tensioning roller 27 into contact with the film to tension the film to be cut.

[0031] like Figure 1 As shown, in some embodiments, the cutter 25 is located between the take-up roller 26 and the tension roller 27; wherein the cutter 25 is adapted to cut the film tensioned between the take-up roller 26 and the tension roller 27.

[0032] In this embodiment, by setting a tension roller 27, the film between the tension roller 27 and the winding pressure roller 26 is tensioned, thereby facilitating the neat cutting of the film by the cutter 25.

[0033] In some embodiments, the two first swing arms 21 are connected by a first synchronous shaft, so that the two first swing arms 21 can rotate synchronously by driving the first synchronous shaft to rotate through a first driver.

[0034] In some embodiments, the two second swing arms 24 are connected by a second synchronous shaft, so that the two second swing arms 24 can rotate synchronously by driving the second synchronous shaft to rotate through a second driver.

[0035] In some embodiments, a groove is provided on the surface of the first swing arm 21, and a slider is provided on the mounting plate 23. The cylinder 22 pushes the mounting plate 23 to move within the groove of the first swing arm 21, thereby guiding and restricting the movement direction of the mounting plate 23.

[0036] like Figure 1 As shown, in some embodiments, the winding pressure roller 26, the cutter 25, and the tension roller 27 are close to the same plane on the side facing the film.

[0037] Specifically, the cutter 25 is mounted on a linear motion pair. When not in operation, the linear motion pair positions the cutter 25 on one side of the film. When the cutter 25 is cutting, the linear motion pair drives the cutter 25 to move along the width direction of the film, thereby cutting the film.

[0038] In this embodiment, when the first swing arm 21 rotates to the desired position, the winding pressure roller 26 and the tension roller 27 bring the film to be cut into a horizontal position; wherein, the blade of the cutter 25 is slightly higher than the film, thereby facilitating the cutting of the film.

[0039] like Figure 1 As shown, in some embodiments, the rotating frame 1 is provided with two take-up cores 11; the rotating frame 1 is also provided with two guide rollers 12, and the two take-up cores 11 and the two guide rollers 12 are orthogonally distributed.

[0040] Specifically, the rotating frame 1 is in the shape of a cross, with two take-up cores 11 located at the horizontal ends of the rotating frame 1 and two guide rollers 12 located at the vertical ends of the rotating frame 1.

[0041] At least one embodiment provides a film splicing mechanism, comprising: a pair of first swing arms 21, each of the first swing arms 21 being provided with a cylinder 22, a mounting plate 23 being provided on the drive end of the cylinder 22, and a second swing arm 24 being provided on the mounting plate 23; wherein a cutter 25 is provided between the two mounting plates 23, and a splicing pressure roller 26 is provided between the two second swing arms 24; the first swing arms 21 are adapted to press the film onto the empty take-up core 11 by rotating the splicing pressure roller 26; the second swing arms 24 cooperate with the cylinders 22 to drive the splicing pressure roller 26 to revolve around the take-up core 11.

[0042] In this embodiment, by setting up the winding mechanism 2, the winding pressure roller 26 of the winding mechanism 2 presses the film onto the take-up core 11 whose surface is coated with adhesive. Then, the cutter 25 cuts the film between the empty take-up core 11 and the full take-up core 11. Finally, through the joint cooperation of the second swing arm 24 and the cylinder 22, the winding pressure roller 26 revolves around the take-up core 11, thereby attaching the excess film to the take-up core 11 and preventing the excess film from folding or wrinkling.

[0043] like Figure 1 As shown, in some embodiments, a tensioning roller 27 is provided between the two mounting plates 23; wherein the first swing arm 21 is adapted to rotate to bring the tensioning roller 27 into contact with the film to tension the film to be cut.

[0044] like Figure 1 As shown, in some embodiments, the cutter 25 is located between the take-up roller 26 and the tension roller 27; wherein the cutter 25 is adapted to cut the film tensioned between the take-up roller 26 and the tension roller 27.

[0045] In this embodiment, by setting a tension roller 27, the film between the tension roller 27 and the winding pressure roller 26 is tensioned, thereby facilitating the neat cutting of the film by the cutter 25.

[0046] like Figure 1 As shown, in some embodiments, the winding pressure roller 26, the cutter 25, and the tension roller 27 are close to the same plane on the side facing the film.

[0047] Specifically, the cutter 25 is mounted on a linear motion pair. When not in operation, the linear motion pair positions the cutter 25 on one side of the film. When the cutter 25 is cutting, the linear motion pair drives the cutter 25 to move along the width direction of the film, thereby cutting the film.

[0048] In this embodiment, when the first swing arm 21 rotates to the desired position, the winding pressure roller 26 and the tension roller 27 bring the film to be cut into a horizontal position; wherein, the blade of the cutter 25 is slightly higher than the film, thereby facilitating the cutting of the film.

[0049] In summary, this film splicing device and film splicing mechanism, by setting up the splicing mechanism 2, allows the splicing pressure roller 26 of the splicing mechanism 2 to press the film onto the take-up core 11 coated with adhesive. Then, the cutter 25 cuts the film between the empty take-up core 11 and the full take-up core 11. Finally, through the joint cooperation of the second swing arm 24 and the cylinder 22, the splicing pressure roller 26 revolves around the take-up core 11, thereby attaching the excess film to the take-up core 11 and preventing the excess film from folding or wrinkling.
