Description

Technical Field

[0001] This utility model relates to the technical field of hot stamping printing, and in particular to a film peeling knife assembly. Background Technology

[0002] In the field of hot stamping printing, film removal is a crucial step. Its main purpose is to peel the hot stamping film from the surface of the printing medium, ensuring that the metal foil layer remains accurately within the hot stamping pattern area; excess metal foil is peeled off along with the hot stamping film. The typical steps for hot stamping printing using a label printer are: the label printer prints the pattern on the printing medium → hot stamping film is applied to the printed pattern → hot pressing → film removal → application of transfer film. Existing technologies utilize dedicated film removal rollers. For example, patent CN218111747U, a label film removal and coating integrated printer, discloses a film removal roller specifically designed to separate the old film from the surface of the A-film. During use, the printing medium forms a wrapping angle on the side of the film removal roller, increasing the friction between the roller and the hot stamping film. Under this friction, the metal foil layer in the hot stamping pattern area may peel off along with the hot stamping film, damaging the final hot stamping effect. There is an urgent need for an alternative structure that can guarantee the hot stamping effect. Utility Model Content

[0003] The purpose of this invention is to solve the above-mentioned problems and provide a film peeling knife assembly.

[0004] The technical solution of this utility model is as follows: A film peeling knife assembly includes a horizontally arranged film peeling knife; the film peeling knife is generally strip-shaped, with its front two ends connected to the side wall of the crystal labeling machine, realizing the connection between the film peeling knife and the side wall of the crystal labeling machine; the rear end face of the film peeling knife is the film peeling working surface, which abuts against the hot stamping film on the surface of the printing medium, restricting the hot stamping film; the lower edge of the film peeling working surface is provided with a peeling slope, which on the one hand reduces the area of ​​the film peeling working surface and reduces the friction between the film peeling working surface and the hot stamping film, and on the other hand enables the printing medium to be deflected as far back as possible and the hot stamping film to be deflected as far forward as possible, reducing the actual area of ​​the film peeling working surface in contact with both the printing medium and the hot stamping film at the same time.

[0005] Preferably, the peeling surface is rounded to avoid cutting the hot stamping film.

[0006] Preferably, the film-removing blade assembly further includes angle adjustment mechanisms symmetrically arranged at both ends of the film-removing blade; the angle adjustment mechanism includes a vertically arranged angle adjustment plate, a fixed axis screw, and a locking screw; the upper end of the angle adjustment plate is connected to the front end of the film-removing blade; the angle adjustment plate has a horizontally penetrating fixed axis hole and an arc-shaped elongated hole; the fixed axis screw passes through the fixed axis hole and is threadedly connected to the side wall of the crystal labeling machine; the arc of the arc-shaped elongated hole is concentric with the fixed axis hole; the locking screw passes through the arc-shaped elongated hole and is threadedly connected to the side wall of the crystal labeling machine; the fixed axis screw and the locking screw realize the connection between the angle adjustment plate and the side wall of the crystal labeling machine; wherein the fixed axis screw acts as the fixed axis of the angle adjustment plate; the angle adjustment plate, carrying the film-removing blade, deflects vertically around the fixed axis screw; the locking screw locks after the vertical deflection angle is adjusted; the arc-shaped elongated hole limits the deflection range of the angle adjustment plate and the film-removing blade; different deflection angles of the film-removing blade result in different hot stamping forming effects; by adjusting the vertical deflection angle of the film-removing blade, the hot stamping forming effect is optimized.

[0007] Furthermore, an ear plate extends horizontally from the upper edge of the front side of the adjustment plate; the film peeling knife assembly also includes a connecting screw; the connecting screw passes through the front side of the film peeling knife and is threadedly connected to the ear plate; the film peeling knife and the adjustment plate are detachably connected to facilitate the replacement of the film peeling knife.

[0008] Furthermore, the ear plate is provided with connecting screw holes that match the connecting screws to establish a connection; there are two connecting screws on the ear plate to ensure the connection strength between the angle adjustment plate and the film peeling knife.

[0009] Furthermore, the two connecting screw holes are evenly distributed along the side edge of the film-removing blade to minimize the space along the length of the film-removing blade.

[0010] Furthermore, the end face of the film peeling knife is provided with a relief groove; the side of the relief groove is a plane parallel to the top surface of the film peeling knife; the ear plate is in contact with the side of the relief groove; the setting of the relief groove allows the peeling slope to be extended as much as possible, so that the film peeling working surface can be smaller.

[0011] Furthermore, the side edge of the clearance groove is aligned with the edge of the ear plate, so that the ear plate does not interfere with the peeling slope operation as much as possible.

[0012] The beneficial effects of this utility model are as follows: The film-removing knife assembly of this utility model has the following advantages: (1) The actual contact area between the peeling knife of this utility model and the printing medium and hot stamping film is smaller, and it can also limit the printing medium and hot stamping film sufficiently to ensure the final hot stamping forming effect. (2) The fixed-axis screw and locking screw of this utility model realize the connection between the angle adjustment plate and the side wall of the crystal label machine; wherein the fixed-axis screw acts as the fixed axis of the angle adjustment plate; the angle adjustment plate, with the film peeling knife, deflects vertically around the fixed-axis screw; the locking screw locks after the vertical deflection angle is adjusted; the arc-shaped long hole limits the deflection range of the angle adjustment plate and the film peeling knife; different deflection angles of the film peeling knife result in different hot stamping forming effects; by adjusting the vertical deflection angle of the film peeling knife, the hot stamping forming effect is optimized.

[0014] Example 1: See Figure 1-6 A film peeling blade assembly includes a horizontally arranged film peeling blade; the film peeling blade is generally strip-shaped, with its front two ends connected to the side wall 0 of the crystal labeling machine, realizing the connection between the film peeling blade and the side wall 0 of the crystal labeling machine; the rear end face of the film peeling blade is a film peeling working surface 11, which abuts against the hot stamping film on the surface of the printing medium, restricting the hot stamping film; the lower edge of the film peeling working surface 11 is provided with a peeling slope 12, which on the one hand reduces the area of ​​the film peeling working surface 11 and reduces the friction between the film peeling working surface 11 and the hot stamping film, and on the other hand enables the printing medium to be deflected as far back as possible and the hot stamping film to be deflected as far forward as possible, reducing the actual area of ​​the film peeling working surface 11 in contact with both the printing medium and the hot stamping film at the same time.

[0015] Compared with the prior art, this utility model uses a film peeling knife instead of a film peeling roller for film peeling; the actual contact area between the film peeling knife and the printing medium and hot stamping film is smaller, and it can also provide sufficient restraint for the printing medium and hot stamping film to ensure the final hot stamping forming effect.

[0016] The peeling surface 11 is rounded to avoid cutting the hot stamping film.

[0017] The film-removing blade assembly also includes angle adjustment mechanisms symmetrically arranged at both ends of the film-removing blade; the angle adjustment mechanism includes a vertically arranged angle adjustment plate 21, a fixed axis screw 22, and a locking screw 23; the upper end of the angle adjustment plate 21 is connected to the front end of the film-removing blade; the angle adjustment plate 21 has a horizontally penetrating fixed axis hole and an arc-shaped elongated hole 212; the fixed axis screw 22 passes through the fixed axis hole and is threaded to the side wall of the crystal labeling machine; the arc of the arc-shaped elongated hole 212 is concentric with the fixed axis hole; the locking screw 23 passes through the arc-shaped elongated hole 212 and is threaded to the side wall of the crystal labeling machine. Connection: The fixed-axis screw 22 and locking screw 23 connect the angle adjustment plate 21 to the side wall 0 of the crystal label machine; the fixed-axis screw 22 acts as the fixed axis of the angle adjustment plate 21; the angle adjustment plate 21, with the film peeling knife, deflects vertically around the fixed-axis screw 22; the locking screw 23 locks after the vertical deflection angle is adjusted; the arc-shaped elongated hole 212 limits the deflection range of the angle adjustment plate 21 and the film peeling knife; different deflection angles of the film peeling knife result in different hot stamping forming effects; by adjusting the vertical deflection angle of the film peeling knife, the hot stamping forming effect is optimized.

[0018] An ear plate 213 extends horizontally from the upper edge of the front side of the adjustment plate 21; the film peeling knife assembly also includes a connecting screw 3; the connecting screw 3 passes through the front side of the film peeling knife and is threadedly connected to the ear plate 213; the film peeling knife and the adjustment plate 21 are detachably connected to facilitate the replacement of the film peeling knife.

[0019] The ear plate 213 is provided with a connecting screw hole 2131 that matches the connecting screw 3, and a connection is established with the connecting screw 3; there are two connecting screws 3 on the ear plate 213 to ensure the connection strength between the angle adjustment plate 21 and the film peeling knife.

[0020] Two connecting screw holes 2131 are evenly distributed along the side edge of the film-removing blade to minimize the space along the length of the film-removing blade.

[0021] The end of the film peeling knife is provided with an elongated hole 14 along the length of the film peeling knife; the connecting screw 3 passes through the elongated hole 14 and connects with the connecting screw hole 2131; the elongated hole 14 compensates for the manufacturing error and installation error of the film peeling knife.

[0022] The working principle of this embodiment is as follows: The film-removing working surface 11 restricts the hot stamping film; the peeling slope 12 reduces the area of ​​the film-removing working surface 11 and the friction between the film-removing working surface 11 and the hot stamping film, and on the other hand, it allows the printing medium to deflect backward as much as possible and the hot stamping film to deflect forward as much as possible, reducing the actual contact area between the film-removing working surface 11 and the printing medium and the hot stamping film at the same time, thus ensuring the final hot stamping effect; the fixed axis screw 22 and the locking screw 23 connect the angle adjustment plate 21 to the side wall 0 of the crystal label machine; the fixed axis screw 22 acts as the fixed axis of the angle adjustment plate 21; the angle adjustment plate 21, with the film-removing blade, deflects vertically around the fixed axis screw 22; the locking screw 23 locks the plate after the vertical deflection angle is adjusted; the arc-shaped elongated hole 212 limits the deflection range of the angle adjustment plate 21 and the film-removing blade; different deflection angles of the film-removing blade result in different hot stamping effects; by adjusting the vertical deflection angle of the film-removing blade, the optimal hot stamping effect can be achieved.

[0023] Example 2: Example 2 is basically the same as Example 1, and the similarities will not be repeated. The difference is that: the end face of the film peeling knife is provided with a relief groove 13; the side of the relief groove 13 is a plane parallel to the top surface of the film peeling knife; the ear plate 213 is in contact with the side of the relief groove 13; the setting of the relief groove 13 allows the peeling slope 12 to be extended as much as possible, so that the film peeling working surface 11 can be smaller.

[0024] The side edge of the clearance groove 13 is aligned with the edge of the ear plate 213, so that the ear plate 213 does not interfere with the operation of the peeling slope 12 as much as possible.
