Description

Technical Field

[0001] The invention relates to the technical field of hot stamping equipment, in particular to an equipment and a method for uniformly hot stamping the surface of a conical flask. Background Art

[0002] Although the existing hot stamping equipment adopts the method of rotating the hot stamping paper during the hot stamping process, the effect during actual processing is not very good.

[0003] For example, the Chinese patent document "A Hot Stamping Device for Bottle Decoration," published with publication number CN22118820U, discloses in detail: a hot stamping device for bottle decoration, comprising a mounting frame, a swing assembly, a lifting mechanism, and a motion compensation assembly. When the lifting mechanism drives the rubber wheel downward, the hot stamping paper is pressed against the surface of the substrate to be hot stamped for hot stamping. By providing a swing assembly and a motion compensation assembly, utilizing the swing assembly as a swinging structure in conjunction with the motion compensation assembly, the rubber wheel presses the hot stamping paper to form a certain angle with the hot stamping position of the bottle body, allowing the fan-shaped hot stamping surface to be hot stamped evenly and consistently, avoiding uneven patterns. This device can meet the needs of different products and solves the problem of uneven patterns that can occur when hot stamping conical bottles with existing hot stamping equipment. It has broad market prospects.

[0004] The above-mentioned prior art does not consider the relationship between the rotation axis of the hot stamping paper and the diameter of the cone apex of the conical flask during rotation, nor does it consider that the conical flask can be rotated until the waistline coincides with the horizontal plane so that there is line contact between the hot stamping area, the hot stamping paper and the hot stamping head. Therefore, the overall effect of pattern improvement is still poor. Summary of the Invention

[0008] The present invention provides a working method of a device for uniformly hot stamping the surface of a cylindrical bottle: in the first step, the sliding plate, the connecting arm, the hot stamping paper releasing mechanism and the hot stamping paper winding mechanism are driven to move forward and backward by adjusting the first sliding mechanism and the second sliding mechanism, so that the hot stamping paper moves to the hot stamping area on the surface of the cylindrical bottle; in the second step, the vertical linear module drives the horizontal linear module and the first sliding mechanism, the second sliding mechanism, the second slide plate, the sliding plate, the electric turntable, the connecting arm and the hot stamping head connected to the horizontal linear module to move downward, so that the pressure roller of the hot stamping head contacts the surface of the cylindrical bottle; in the third step, the hot stamping paper is released from the hot stamping paper releasing mechanism and wound up by the hot stamping paper winding mechanism, and the hot stamping head forms the hot stamping paper on the outer surface of the cylindrical bottle, and the cylindrical bottle is also driven by the clamping mechanism to rotate clockwise; in the fourth step, the vertical linear module drives the horizontal linear module and the first sliding mechanism, the second sliding mechanism, the second slide plate, the sliding plate, the electric turntable, the connecting arm and the hot stamping head connected to the horizontal linear module to move upward and reset.

[0009] According to a further technical solution, the cone vertex of the conical flask refers to the intersection of the oblique lines on both sides of the vertical section of the conical flask.

The clamping mechanism swings the conical flask until the upper end projection line of the vertical section of the conical surface coincides with the horizontal plane, so that the part of the conical surface in contact with the horizontal plane is the oblique length of the conical surface. After the conical flask is continuously driven to rotate by the clamping mechanism, the hot stamping paper also moves in a fan-shaped trajectory around the rotation axis of the electric turntable.

The arc-shaped trajectory just fits and is consistent with the conical surface of the conical bottle in the hot stamping area, avoiding the formation of a movement angle between the hot stamping paper and the conical bottle surface due to the tangential movement of the hot stamping paper, which affects the pattern formation.

[0016] 3. The clamping mechanism swings the conical flask while clamping it, so that the outer surface of the conical flask faces upward and its top waistline coincides with the horizontal plane, which also avoids forming an angle with the hot stamping paper and affecting the pattern forming effect.

[0017] Fourth, through the third sliding mechanism, a wider adjustment distance can be provided for the hot stamping paper releasing mechanism, the hot stamping paper winding mechanism and the hot stamping paper when the conical flask is inverted. When the rotation axis of the electric turntable is located at the front position, the hot stamping paper releasing mechanism, the hot stamping paper winding mechanism and the hot stamping paper can also be located on the outer surface of the conical flask at the rear position.

After the rotation motor 34 operates, it drives the rotating matching block 43, the matching plate 36, the sliding bracket 38, the base 42, the guide rod 39, the connecting rod 41, the bottle rotation motor 35, the extrusion cylinder 33, the adsorption ejector 32 and the push plate 31 to rotate. The clamping mechanism 14 swings the conical bottle until the upper end projection line of the vertical section of the cone coincides with the horizontal plane.

[0043] Advantageously, where Figure 6 and Figure 14 As shown, a pressing mechanism 15 for pushing the bottle upward is further provided below the clamping mechanism 14, and the pressing mechanism 15 includes a shell 21, two guide sliders 25 are fixedly provided in the shell 21, a rack 27 is slidingly provided in the guide slider 25, a lifting plate 24 is fixedly provided on the top of the rack 27, a plurality of rollers 23 are rotatably provided on the top of the lifting plate 24, two gears 26 that mesh with each other are rotatably provided in the shell 21, the gear 26 is meshed with the rack 27, and a lifting motor 22 is fixedly provided on the rear side of the shell 21, and the lifting motor 22 is power-connected to one of the gears 26.

[0044] The lifting motor 22 drives one of the gears 26 to rotate. Since the gears 26 are meshed with each other, the other gear 26 is rotated. Since the gear 26 is meshed with the rack 27, the rack 27 is driven to move upward in the guide slider 25. Since the rack 27 is fixedly connected to the lifting plate 24, the roller 23 is driven to push the bottle upward to offset the downward pressure on the bottle during hot stamping.
