A magnetic imaging rotary plateless hot stamping machine

Abstract

The present invention provides a magnetic imaging rotary plateless hot stamping machine, comprising an imaging drum, an imaging head and a particle supply assembly for supplying heated hot stamping particles. Since the imaging drum is arranged above the hot stamping material belt, the imaging head and the particle supply assembly are both arranged near the imaging drum. The imaging head is used to magnetize the surface of the imaging drum according to a predetermined hot stamping image, thereby forming a corresponding latent magnetic image on the surface of the imaging drum. The latent magnetic image adsorbs the heated hot stamping particles, thereby causing the heated hot stamping particles to form a protruding hot particle image on the surface of the imaging drum. The imaging drum hot stamps a portion of the coating on the hot stamping material belt onto the surface of the hot stamping product through the particle image. The magnetic imaging rotary plateless hot stamping machine of the present invention does not need to use a hot stamping plate or a printing needle for hot stamping, thereby significantly reducing the use cost and greatly improving the hot stamping efficiency, making the personalized design of hot stamping products more popular.

Description

Technical Field

[0002] With the acceleration of the digitalization process of printing in my country, digital hot stamping has become an indispensable new process in the printing industry due to its variability, on-demand and personalization.

[0003] At present, most of the digital plateless hot stamping machines on the market use a pin-type print head. The hot stamping process is as follows: the pin-type print head is instantly heated to generate high temperature, and then the pin-type print head is pressed down to stamp the hot stamping material onto the surface of the hot stamping product until the hot stamping process is completed. During the hot stamping process, because the high temperature of the pin-type print head will reduce the hot stamping quality, it is also necessary to use a print cover to cool the pin-type print head as a whole to ensure the hot stamping quality.

[0004] Since the printing pin is frequently exposed to instantaneous high pressure and drastic temperature changes during the hot stamping process, the service life of the printing pin is short, thereby increasing the use cost of the digital plateless hot stamping machine.

[0005] At the same time, since the printing needle needs to be cooled during the hot stamping process, the entire hot stamping process takes a long time and the hot stamping efficiency is low.

[0092] Step S2 : the imaging head 41 forms a corresponding positive latent magnetic image on the surface of the imaging drum 31 according to the predetermined hot stamping image.

[0093] Step S3, when the latent magnetic image rotates with the imaging drum 31 to the vicinity of the particle supply assembly 42, the latent magnetic image absorbs the heated hot stamping particles C. Because the attraction of the magnetic roller 423 to the heated hot stamping particles C is smaller than the attraction of the latent magnetic image to the heated hot stamping particles C, the latent magnetic image absorbs the heated hot stamping particles C on the surface of the magnetic roller 423 through the accommodating box opening 4211, so that the heated hot stamping particles C form a protruding hot particle image on the surface of the imaging drum 31.

[0094] Step S4, when the raised particle image rotates with the imaging drum 31 to the pressing area between the imaging drum 31 and the embossing roller 32, the imaging drum 31 squeezes a portion of the hot stamping material strip A through the particle image, and presses the hot stamping material strip A and the receiving product through the embossing roller 32, thereby hot stamping a portion of the hot stamping material strip A onto the surface of the receiving product, thereby forming a predetermined hot stamping image. At this time, the receiving product is in contact with the rubber layer 322 of the embossing roller 32.

[0095] Step S5 , when the protruding particle image rotates with the imaging drum 31 to the outer shell opening 511 of the particle erasing assembly 50 , the rotating brush roller 52 brushes the particle image off the surface of the imaging drum 31 through the bristles 521 .

[0096] In step S6, when the latent magnetic image rotates with the imaging drum 31 to the vicinity of the demagnetization head 60, the demagnetization head 60 demagnetizes the surface of the imaging drum 31, thereby eliminating the latent magnetic image.

[0097] Functions and Effects of Embodiment 1

[0098] According to the magnetic imaging rotary plateless hot stamping machine involved in this embodiment, it includes an imaging drum, an imaging head, and a particle supply assembly for supplying heated hot stamping particles. Because the imaging drum is arranged above the hot stamping material belt, the imaging head and the particle supply assembly are both arranged near the imaging drum. The imaging head is used to magnetize the surface of the imaging drum according to the predetermined hot stamping image, thereby forming a corresponding latent magnetic image on the surface of the imaging drum. The latent magnetic image adsorbs the heated hot stamping particles, thereby causing the heated hot stamping particles to form a protruding hot particle image on the surface of the imaging drum. The imaging drum uses the particle image to stamp a part of the coating on the hot stamping material belt onto the surface of the hot stamping product. Therefore, the magnetic imaging rotary plateless hot stamping machine of this embodiment does not need to use a printing pin for hot stamping, thereby significantly reducing the cost of use and greatly improving the hot stamping efficiency.

[0099] Because the particle supply assembly of the present embodiment includes a particle containing box and a heating wire, the particle containing box is used to contain hot stamping particles, and the heating wire is used to heat the hot stamping particles, the particle supply assembly can provide heated hot stamping particles.

[0100] Furthermore, because the particle holding box of the present embodiment has a holding box opening facing the imaging drum surface, the particle supply assembly also includes a magnetic roller, which can absorb the heated hot stamping particles and rotate to the holding box opening, and the attraction of the magnetic roller to the heated hot stamping particles is smaller than the attraction of the latent magnetic image to the heated hot stamping particles, so the latent magnetic image on the imaging drum surface can absorb the heated hot stamping particles from the particle supply assembly, thereby forming a particle image.

[0101] Because the present embodiment further comprises a particle erasing assembly, which includes a rotating brush roller, and the bristles of the brush roller are in contact with the surface of the imaging drum, the particle image can be brushed off the surface of the imaging drum, thereby achieving the hot stamping of multiple predetermined hot stamping images.

[0102] Because this embodiment also includes a demagnetization head for demagnetizing the surface of the imaging drum, the latent magnetic pattern can be eliminated from the surface of the imaging drum, so that there will be no mutual superposition interference of latent magnetic images when multiple hot stamping images are stamped.

[0103] Because the hot stamping mechanism of this embodiment also includes a embossing roller arranged below the hot stamping product and corresponding to the imaging drum, and when the particle image squeezes a part of the hot stamping material tape, the embossing roller can cooperate to press the hot stamping material tape and the hot stamping product together, so that the particle image can fully contact the hot stamping material tape, making the predetermined hot stamping image printed clearer.

[0104] Furthermore, because the outer layer of the embossing roller is a rubber layer and the contact with the paper feeding platform carrying the product to be hot-stamped is a flexible abutment during pressing, the impact pressure of the embossing roller during hot stamping is a flexible buffer, so that the pressure of the hot stamping process is uniform and the coating on the hot stamping material belt is better transferred to the hot stamping material belt.

[0105] <Example 2>

[0106] In the second embodiment, the same symbols are given to the same structures as those in the first embodiment, and the same descriptions are omitted.

[0107] Fig.10 It is a schematic structural diagram of a magnetic imaging rotary plateless hot stamping machine in the second embodiment of the present invention.

[0108] like Fig.10 As shown, in the second embodiment, the structure of the magnetic imaging rotary plateless hot stamping machine 100 is different from that of the first embodiment in that:

[0109] In this embodiment, the hot stamping product D is a product that is hot stamped separately, rather than a hot stamping paper tape as in the first embodiment, and the hot stamping product D is not limited to paper, but may also be a paper box.

[0110] The embossing roller 32 is omitted in the hot stamping mechanism 30 .

[0111] The first conveying component 11 of the ironing product conveying mechanism 10 has, in addition to a driving shaft 111 , a tensioning shaft 112 and at least one guide roller 113 , a paper conveying platform 114 , a vacuum suction belt 115 and a vacuum pump 116 .

[0112] The paper feeding platform 114 is arranged horizontally.

[0113] The vacuum adsorption belt 115 is arranged on the paper feeding platform 114. The vacuum adsorption belt 115 is used to carry the hot product D. The surface of the vacuum adsorption belt 115 has multiple adsorption holes (not marked in the drawings). In this embodiment, the shape of the vacuum adsorption belt 115 is "O"-shaped. The adsorption holes have openings arranged on the end face of the vacuum adsorption belt 115, and the distribution range of the multiple adsorption holes covers the entire vacuum adsorption belt 115.

[0114] When the ironing product D is carried on the vacuum adsorption belt 115, the ironing product D covers a plurality of adsorption holes, that is, the adsorption holes located at the upper end surface of the vacuum adsorption belt 115 are blocked by the ironing product D. The part of the vacuum adsorption belt 115 covered by the ironing product D is called the ironing product pressing part 10a.

[0115] The vacuum pump 116 is connected to the multiple adsorption holes. The vacuum pump 116 sucks air into the multiple adsorption holes to form a vacuum in the multiple adsorption holes located in the hot product pressing part 10a, thereby adsorbing the hot product D on the hot product pressing part 10a.

[0116] The vacuum adsorption belt 115 is sleeved on the driving shaft 111 and the tensioning shaft 112. In this embodiment, the vacuum adsorption belt 115 is sleeved on the driving shaft 111, the tensioning shaft 112 and the guide roller 113 at the same time, and the driving shaft 111 and the tensioning shaft 112 are both located below the paper feeding platform 114.

[0117] The surface of the guide roller 113 abuts against the lower surface of the vacuum adsorption belt 115, so as to provide tension for the vacuum adsorption belt 115 and ensure that the vacuum adsorption belt 115 always remains parallel to the paper feeding platform 114. In the present embodiment, there are two guide rollers 113, and the axes of the two guide rollers 113 are parallel to each other and are both located in the first horizontal plane B1, so that the vacuum adsorption belt 115 is always in a horizontal position.

[0118] A driving shaft 111 is installed on the output end of the first driving motor 12 , and the first driving motor 12 is used to drive the driving shaft 111 to rotate, thereby driving the vacuum adsorption belt 115 to move.

[0119] The control processing device 70 has not only all the functional components as in the first embodiment, but also a vacuum pump driving unit 713 .

[0120] The processing side control unit 712 controls the vacuum pump driving unit 713 to generate a vacuum pump driving signal according to the operator's start signal, and the processing side communication unit 705 sends the vacuum pump driving signal to the vacuum pump 116, thereby driving the vacuum pump 116 to suck air from the multiple adsorption holes on the vacuum adsorption belt 115.

[0121] Functions and Effects of Embodiment 2

[0122] Because the first conveying component in this embodiment uses a vacuum pump to suck air from the adsorption holes on the vacuum adsorption belt so that the vacuum adsorption belt adsorbs and conveys the hot-stuffed product, there is no need to sleeve the two ends of the hot-stuffed product on the driving shaft and the tensioning shaft as in Example 1, and the surface of the hot-stuffed product can be hot-stamped. Therefore, in this embodiment, small hot-stuffed products can be hot-stamped individually, and the hot-stamped products are not limited to hot-stamping paper tapes.

[0123] The above-mentioned implementation modes are preferred cases of the present invention and are not used to limit the protection scope of the present invention. Various deformations or modifications that can be made by ordinary technicians in this field without creative work within the scope of the attached claims are still within the protection scope of this patent.
