Description

TECHNICAL FIELD

[0001] The utility model relates to clothing hot stamping equipment technical field, specifically point to a kind of clothing hot stamping film tearing device. BACKGROUND

[0002] When producing T-shirts and other clothes, the surface usually needs to be hot stamped with patterns; one side of these patterns is glued, and the other side is attached with a protective film. This protective film is usually a medium-hardness film, which not only protects the patterns from being damaged, but also prevents the patterns from bending, folding and deforming during the hot stamping process. Since the patterns to be hot stamped on the clothes are very thin, after hot stamping is completed, the protective film is almost attached to the clothes fabric. In addition, the clothes are flexible. When the protective film is peeled off by mechanical means, it is difficult to clamp the edge of the protective film, and the clothes fabric is easily damaged during clamping. In actual production, the protective film is often peeled off manually, which obviously limits the production efficiency. SUMMARY

[0003] The utility model aims at providing a film tearing device that can efficiently and reliably peel off the protective film.

[0004] To achieve the above-mentioned purpose, the utility model employs the following technical solutions:

[0005] A clothing hot stamping film tearing device is used to tear off the protective film of patterns after hot stamping on clothes, and the protective film is a medium-hardness film. The device includes a bearing plate, a mechanical arm, and a peeling mechanism provided at the end of the mechanical arm. The peeling mechanism includes a mounting seat fixed to the end of the mechanical arm, and a spade assembly and a film pressing assembly provided on the mounting seat in opposite directions along the X-axis.

[0006] The spade assembly includes a spade part extending towards the film pressing assembly, and a film clamping cylinder fixed to the mounting seat for driving the spade part to move along the X-axis.

[0007] The film pressing assembly includes a film pressing block mounted on the mounting seat for rotation around the Y-axis, and a limiting assembly for limiting the rotation amplitude of the film pressing block. The bottom end of the film pressing block has a film pressing plane, and the film pressing plane has a straight edge along the Y-axis on the side close to the spade assembly.

[0008] In the reset state, the film pressing block rotates towards the side of the spade assembly, causing the film pressing plane to tilt. When pressed, the straight edge abuts against the protective film, and the bottom surface of the spade part abuts against the clothes. When pressed further, the film pressing block rotates until the film pressing plane is flat against the surface of the protective film, so that the edge of the protective film is lifted by the straight edge. The spade part moves towards the film pressing block under the drive of the film clamping cylinder to jointly clamp the edge of the protective film, and moves with the mechanical arm to tear off the protective film.

[0009] In a preferred embodiment, the center of gravity of the pressing block is biased to one side of the blade assembly.

[0010] In a preferred embodiment, a spring is further arranged between the upper end of the pressing block and the mounting base for driving the pressing block to reset.

[0011] In a preferred embodiment, the mounting base has two side plates arranged along the Y axis at intervals, and the pressing block is mounted between the two side plates; the limiting assembly comprises a limiting pin fixed along the Y axis between the two side plates, and a Y-axis guide hole provided on the pressing block for the limiting pin to pass through, the guide hole being an elongated hole with a radial profile larger than the limiting pin.

[0012] In a preferred embodiment, an adjusting screw is threadedly connected to the pressing block at the position of the guide hole, the adjusting screw penetrates into the guide hole along the radial direction for fine adjustment of the highest or lowest position of the rotation of the pressing block.

[0013] In a preferred embodiment, the side opposite to the blade part of the pressing block forms a clamping surface for clamping the protective film.

[0014] In a preferred embodiment, the bottom surface of the blade part is a smooth plane.

[0015] In a preferred embodiment, the film tearing device further comprises a pressing assembly arranged along the X axis outside the blade assembly, the pressing assembly comprising a vertically mounted pressing cylinder and a pressing plate arranged at the end of the pressing cylinder.

[0016] The above-mentioned scheme has the following beneficial effects: during operation, the blade assembly and the pressing assembly are synchronously pressed down by the mechanical arm, the straight edge of the pressing block abuts against the protective film, and the bottom surface of the blade part abuts against the clothes, and when the pressing continues, the pressing block rotates to the pressing plane being flat against the surface of the protective film, so that the edge of the protective film is squeezed up by the straight edge; and the blade part moves towards the pressing block under the driving of the clamping cylinder to jointly clamp the edge of the protective film and moves with the mechanical arm to tear off the protective film. The protective film after the edge is raised can be reliably clamped and torn off, and therefore the film tearing device realizes the automatic peeling of the protective film after the clothes is ironed, and obviously improves the production efficiency.
