Description

Technical Field

[0001] The present application relates to the field of coating technology, and in particular to a mobile phone film coating machine with a trimming device. Background Art

[0002] The current coating machine does not have the function of cutting the coating base film during production. It can only coat the original base film in the same width. In the field of original film materials for mobile phone film coating, the size of the base film is basically fixed, and the size of mobile phone film changes with the development of science and technology. Therefore, when coating mobile phone films, it is often difficult to buy base films with suitable widths. You can only buy base films larger than the actual width, which increases the difficulty of coating and the amount of glue used. In this way, not only the cost of the base film increases, but also the cost of glue increases, which greatly increases the manufacturing cost. Utility Model Content

The deflection correction bracket A fixed bracket 221 is extended in the direction of the traction unit 300 at 210, and a cutter assembly is arranged on the fixed bracket 221, and the cutter assembly includes: a support shaft 241 and a cutter 244, the support shaft 241 is arranged on the fixed bracket 221, and the length direction of the support shaft 241 is perpendicular to the unwinding direction of the base film 400 of the correction unit 200, the cutter 244 is arranged on the support shaft 241, and is located in the same horizontal plane as the correction guide roller 230, and the cutting edge direction of the cutter 244 is arranged opposite to the unwinding direction of the base film 400.

[0043] In this embodiment, the size of the base film 400 is cut between the base film 400 roll placement device and the traction device, that is, before the base film 400 is coated, so that the coating material can be saved. Specifically, a cutter assembly capable of shearing the base film 400 is provided on the deviation correction device for correcting the position of the base film 400, and the redundant and uncoated part of the base film 400 is cut in advance, so that during the coating process, the uncoated part of the base film 400 does not need to be coated, thereby saving the coating material. Among them, the cutter assembly includes: a support shaft 241 and a cutter 244. The support shaft 241 is horizontally arranged on the fixed bracket 221, and the length direction of the support shaft 241 is perpendicular to the unwinding direction of the base film 400 of the correction unit 200. When the cutter 244 is set on the support shaft 241, it is located in the same horizontal plane as the correction guide roller 230, and the cutting edge direction of the cutter 244 is set in the opposite direction to the unwinding direction of the base film 400, so as to cut off the excess part of the rolled base film 400.

[0044] In a specific embodiment, the cutter assembly also includes: a cutter fixing frame 242, one end of the cutter fixing frame 242 is a fixed end, the cutter 244 is embedded in the fixed end, and the other end of the cutter fixing frame 242 is a mounting end, the mounting end is sleeved on the support shaft 241, and is used to fix the cutter 244, and can drive the cutter 244 to rotate in the circumferential direction relative to the support shaft 241, and slide in the axial direction, so as to adjust the cutting angle of the cutter 244 relative to the base film 400.

[0045] In a specific embodiment, a locking member is provided at the mounting end of the cutter fixing frame 242 for fixing the cutter fixing frame 242 and the cutter 244 on the supporting shaft 241 of the columnar structure.

[0046] In this embodiment, the locking member includes: a locking nut 243 and an abutment member, which are used to install the cutter fixing frame 242 on the support shaft 241. The inner side of the abutment member and the inner side of the mounting end of the cutter fixing frame 242 are both arc-shaped, and one end of the abutment member is rotatably connected to one end of the arc-shaped mounting end. When the other end of the abutment member rotates to contact the other end of the mounting end of the cutter fixing frame 242, it can form a ring with the inner side of the mounting end. The end of the abutment member that abuts the mounting end is provided with a first mounting hole, and the end of the mounting end that abuts the abutment member is provided with a matching second mounting hole. When the abutment member abuts the mounting end of the cutter fixing frame 242, the second mounting hole is aligned with the first mounting hole.

[0048] There are two pairs of corresponding third fixing holes to stabilize the position of the cutting knife 244 relative to the knife groove.

[0049] In this embodiment, the length direction of the cutter 244 is perpendicular to the length direction of the support shaft, so that the base film 400 can be cut along a straight line when it is unrolled from the deviation correcting device to the traction device.

[0050] In a specific embodiment, the deflection correction bracket 210 includes: a base 210 and a side wall, wherein the side walls are two and are symmetrically arranged on the top of the base 210, and the two side walls are arranged in parallel, one side of the two side walls is opened as a roll-in end, and the roll-in end corresponds to the base film 400 placement unit 100, and the other side is opened as a roll-out end, and the roll-out end corresponds to the traction unit 300. Among them, the deflection correction guide roller 230 is arranged at the roll-in end of the deflection correction unit 200 to correct the position of the base film 400, so that when the base film 400 is coated, the coated material can be applied on the base film 400, and the support shaft 241 is arranged at the roll-out end of the deflection correction unit 200, so that the base film 400 after the position is corrected can be cut.

[0051] In this embodiment, a fixing bracket 221 extends from the side wall of the deflection correcting bracket 210 toward the traction unit 300, and is used to fix the support shaft 241. Specifically, the fixing bracket is a plate-like structure, and the plate surface is parallel to the side wall of the deflection correcting bracket 210 and is in the same vertical plane, providing an installation position for fixing the support shaft 241. Both ends of the support shaft 241 are respectively connected to the two fixing brackets 221, and can be fixed by welding.

[0052] In this embodiment, the knife groove is located between the deflection correction guide roller 230 and the support shaft 241, and the length of the cutter 244 is greater than the spacing distance between the knife groove and the top of the deflection correction guide roller 230, so that the top of the cutter 244 can exceed the base film 400, thereby being able to cut the passing base film 400.

[0053] The cutter 244 is a blade, and the blade is relatively thin, so the base film 400 will not be damaged during cutting.
