In the description of the present invention, unless otherwise specified, "multiple" means two or more.

[0044] In the description of the present invention, it is also necessary to explain that, unless otherwise clearly specified and limited, the terms "set", "install", "connect", and "connect" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0045] The embodiment of the utility model provides a hot stamping machine, which can perform hot stamping on a curved or spherical cup or other products at one time, thereby improving the hot stamping efficiency and hot stamping quality.

[0046] Combine the following Figure 2-Figure 10 The technical solution provided by the utility model is described in more detail.

[0047] Embodiment 1:

[0048] See also Figure 2-Figure 6 As shown, in the hot stamping machine provided by the utility model, the first cylinder petal 1 and the second cylinder petal 2 can rotate with the corresponding shaft as the axis under the drive of manpower or a driving mechanism, so as to open or close to each other.

[0049] The hot stamping machine comprises a machine body 4, a driving mechanism, a first cylinder petal 1, a second cylinder petal 2 and a vacuum device, wherein: the first cylinder petal 1 and the second cylinder petal 2 are rotatably connected to the machine body 4, and a heating part is arranged on the first cylinder petal 1 and / or the second cylinder petal 2; the driving mechanism is transmission-connected with the first cylinder petal 1 and the second cylinder petal 2, and is used to drive the first cylinder petal 1 and the second cylinder petal 2 to open or close with each other, and when the first cylinder petal 1 and the second cylinder petal 2 are closed, a high-temperature baking internal space 100 is formed for accommodating and heating the product to be hot stamped, and clamping the hot stamping film; the vacuum device is connected with the internal space 100, and is used to suck the air between the hot stamping film and the product to be hot stamped, so that the hot stamping film is tightly wrapped on the hot stamping product.

[0050] Among them, the "inner space 100" formed when the first cylinder petal 1 and the second cylinder petal 2 are closed is not an enclosed space. After the first cylinder petal 1 and the second cylinder petal 2 are closed to clamp the hot stamping film, a closed space is formed between the hot stamping film and the product to be hot stamped. Specifically, after the hot stamping film is clamped in place, the closed space between the hot stamping film and the product to be hot stamped is connected to the vacuum device, so that the vacuum device sucks the air between the hot stamping film and the product to be hot stamped, so that the hot stamping film is tightly wrapped around the hot stamping product.

[0051] That is, in the internal space 100, the hot stamping film clamped in place is connected to the outside atmosphere with the side away from the product to be stamped. This arrangement enables the vacuum device to continuously suck the air between the hot stamping film and the product to be stamped to prevent the hot stamping film from being unable to wrap around the product to be stamped due to the pressure difference.

[0052] The hot stamping machine of this embodiment wraps the cup 200 with the hot stamping film with the printed pattern, closes the first petal 1 and the second petal 2 to form an internal space 100, and clamps the hot stamping film to form a closed space between the hot stamping film and the product to be hot stamped. The vacuum device extracts the air between the hot stamping film and the product to be hot stamped, so that the hot stamping film shrinks along the outer contour of the cup and sticks tightly to the cup. After a certain high-temperature heating time, the pattern on the hot stamping film is hot stamped onto the cup.

[0053] The hot stamping machine can perform hot stamping on a curved or spherical cup 200 or other products at one time, thereby improving the hot stamping efficiency and hot stamping quality.

[0054] The hot stamping machine of this embodiment can be used to stamp patterns on the cup 200 or other products. It can be used for hot stamping products with curved outer contours, such as shuttle-shaped cups, gourd-shaped cups, spherical cups, etc. or other utensils with similar shapes. Of course, it can also be used for products with regular outer contours, such as flat surfaces, curved surfaces, such as cylindrical cups, conical cups, etc.

[0055] As an alternative embodiment, see Figure 4 and Figure 5 , Figure 6 As shown, the driving mechanism includes a driving device 76, a screw rod 71, a first nut portion 72, and a second nut portion 73, wherein: the driving device 76 is connected to the screw rod 71 for driving the screw rod 71 to rotate forward or reversely, and the first nut portion 72 and the second nut portion 73 are both threadedly connected to the screw rod 71; a first transmission rod 81 is fixedly connected to the bottom of the first cylinder petal 1, and the first transmission rod 81 is fixedly connected to the first nut portion 72 through the first connecting rod 10, and one end of the first transmission rod 81 is connected to the body 4 through the shaft portion 80 The second end of the second cylinder flap 2 is fixedly connected to the bottom of the second cylinder flap 2, and the second transmission rod 82 is fixedly connected to the second nut portion 73 through the second connecting rod 11. One end of the second transmission rod 82 is rotationally connected to the body 4 through the shaft portion 80, and the other end is rotationally connected to the second connecting rod 11; the first nut portion 72 and the second nut portion 73 can move toward or away from each other under the drive of the screw rod 71, so that the first cylinder flap 1 and the second cylinder flap 2 rotate around the corresponding shaft portion 80.

[0056] See also Figure 6 As shown, a guide hole 74 is provided on the frame inside the machine body. The guide hole 74 is arranged horizontally. The first connecting rod 10 and the second connecting rod 11 extend into the corresponding guide holes. The guide hole 74 is used to limit the horizontal movement of the first connecting rod 10 or the second connecting rod 11.

[0057] The driving device 76 can be a motor, etc., which drives the screw rod 71 to rotate, and the first nut portion 72 and the second nut portion 73 can move toward or away from each other under the drive of the screw rod 71. Figure 4 , Figure 5 and Figure 6As shown, when the first nut portion 72 and the second nut portion 73 move toward each other, the first connecting rod 10 and the second connecting rod 11 pull the first transmission rod 81 and the second transmission rod 82 to rotate around the shaft portion 80 as the axis, and the first cylinder petal 1 and the second cylinder petal 2 rotate around the shaft portion 80 as the axis and open to each other, and the cup 200 can be put in at this time. When the first nut portion 72 and the second nut portion 73 move away from each other, the first connecting rod 10 and the second connecting rod 11 pull the first transmission rod 81 and the second transmission rod 82 to rotate around the shaft portion 80 as the axis, and the first cylinder petal 1 and the second cylinder petal 2 rotate around the shaft portion 80 as the axis and close to each other.

[0058] As an alternative embodiment, see Figure 4 As shown, the screw rod 71 includes a first thread segment 711 and a second thread segment 712, wherein: the thread rotation directions of the first thread segment 711 and the second thread segment 712 are opposite, and the first thread segment 711 and the second thread segment 712 are arranged at intervals along the length of the screw rod 71; the first nut portion 72 is threadedly connected to the first thread segment 711, and the second nut portion 73 is threadedly connected to the second thread segment 712.

[0059] With such arrangement, a driving device 76 is connected to the screw rod 71 , so as to enable the first nut portion 72 and the second nut portion 73 to move toward or away from each other.

[0060] As an alternative embodiment, see Figure 2 and Figure 4 As shown, sealing baffle assemblies 3 are fixed at both ends of the machine body 4. When the first cylinder petal 1 and the second cylinder petal 2 are closed, the ends of the first cylinder petal 1 and the second cylinder petal 2 are against the sealing baffle, thereby clamping the hot stamping film.

[0061] Specifically, both ends of the hot stamping film are clamped by the ends of the first cylindrical petal 1 and the second cylindrical petal 2 being pressed against the sealing baffle.

[0062] The sealing baffle assembly 3 can cooperate with the first cylinder flap 1 and the second cylinder flap 2 to improve the air tightness of the device. When the vacuum device sucks the air in the internal space 100, the air extraction efficiency can be improved.

[0063] As an alternative embodiment, see Figure 5 As shown, the sealing baffle assembly 3 includes a support plate 31 and an elastic soft baffle 32 . The elastic soft baffle 32 is fixed on the support plate 31 . The ends of the first cylinder petal 1 and the second cylinder petal 2 are both in sealing contact with the elastic soft baffle 32 .

[0064] The support plate 31 is used to fix the elastic soft baffle 32. The elastic soft baffle 32 has a certain elasticity and can cooperate with the first cylinder petal 1 and the second cylinder petal 2 to seal and clamp the hot stamping film, thereby ensuring good sealing performance between the hot stamping film and the hot stamping product.

[0065] As an alternative embodiment, see Figure 3 As shown, when the first cylinder petal 1 and the second cylinder petal 2 are closed, at least a portion of the elastic soft baffle 32 extends into the internal space 100 , and the first cylinder petal 1 and the second cylinder petal 2 are wrapped around the side wall of the elastic soft baffle 32 .

[0066] The above structure can make the elastic soft baffle 32 and the first cylinder petal 1 and the second cylinder petal 2 in sealing contact and sealing cooperation, thereby ensuring that the hot stamping film is firmly clamped.

[0067] As an optional implementation, the first cylinder petal 1 and the second cylinder petal 2 are both arc-shaped cylinder petal structures.

[0068] The above structure makes it easy for the first cylindrical petal 1 and the second cylindrical petal 2 to be wrapped around the side wall of the elastic soft baffle 32, and makes it easy to form an internal space 100 capable of accommodating products such as a cup 200.

[0069] As an alternative embodiment, see Figure 4 As shown, the heating part includes a heating plate 9, and the heating plate 9 is fixed on the inner walls of the first cylinder petal 1 and the second cylinder petal 2.

[0070] The heating plate 9 may be an electric heating plate 9 , which is connected to an external power source and can generate heat when powered on, thereby heating the hot stamping film in the internal space 100 , so that the pattern on the hot stamping film is hot stamped onto the cup 200 .

[0071] As an alternative embodiment, see Figure 6 As shown, the vacuum extraction device of this embodiment includes a vacuum pump 6, the number of vacuum pumps 6 is one or more, the body 4 includes a supporting beam 51, and a pipe joint 53 is provided on the supporting beam 51. One end of the pipe joint 53 is connected to the vacuum pump 6 through a pipeline, and the other end is connected to the internal space 100.

[0072] When the vacuum pump 6 is working, it can suck the air in the internal space 100, especially the air between the hot stamping film and the outer wall of the cup 200, so that the hot stamping film is firmly wrapped on the cup 200, so that the pattern can be printed on the outer wall of the cup 200 after the hot stamping film is heated.

[0073] As an alternative embodiment, see Figure 6 As shown, a support column 52 is provided on the support beam 51, and the support column 52 is used to support the product to be hot stamped.

[0074] Specifically, the two ends of the hot stamping film are clamped against the sealing baffle by the ends of the first cylinder petal 1 and the second cylinder petal 2, and the butt side of the hot stamping film can be inserted into the plug-in seam of the supporting crossbeam 51. A silicone strip or the like can be provided on the side wall of the plug-in seam, so that the vacuum device can suck the air between the hot stamping film and the product to be hot stamped, so that the hot stamping film is firmly wrapped on the cup. The heating unit heats the hot stamping film by air heating.

[0075] The function of the support column 52 is to support the product to be hot stamped, such as the cup 200 , and the shape of the top of the support column 52 matches the outer contour of the product to be hot stamped.

[0076] The hot stamping machine of this embodiment further includes a controller 12 , and the controller 12 is electrically connected to the heating part and the driving device 76 .

[0077] The hot stamping machine of this embodiment, when in operation:

[0078] 1. After power is turned on, set the temperature and time required for hot stamping on the controller 12, and then heat the heating part;

[0079] 2. Place the cup 200 on the support column 52, with both ends of the cup 200 aligned with the elastic soft baffle 32;

[0080] 3. Wrap the cup 200 with a hot stamping film (a plastic-like film that can be stretched and deformed after heating) with a printed pattern, and insert the mating sides of the film into the supporting beams 51 respectively.

[0081] 4. The controller 12 controls the driving device 76 to rotate in one direction and drives the screw 71 to rotate. When the screw rotates, it pushes the first nut part 72 and the second nut part 73 to move away from each other, and drives the first cylinder petal 1 and the second cylinder petal 2 to move towards each other. The two are closed. At this time, a closed space is formed inside the hot stamping film wrapped around the cup 200. The heating part heats the hot stamping film. After a certain period of time, the controller 12 starts to control the vacuum pump 6 to start vacuuming, extracting the air between the hot stamping film and the cup 200, so that the hot stamping film shrinks along the shape of the cup 200 and sticks tightly to the cup body. After a certain high-temperature heating time, the pattern on the hot stamping film is hot stamped on the cup 200, and then the controller 12 controls the vacuum pump 6 to stop vacuuming, and controls the driving device 76 to rotate in the opposite direction. The first cylinder petal 1 and the second cylinder petal 2 open, and then the hot stamping film and the cup 200 are taken out, the hot stamping film is peeled off, and the cup 200 with the hot stamping pattern is completed.

[0082] Embodiment 2:

[0083] The difference between the second embodiment and the first embodiment is that the hot stamping machine of the present embodiment has no driving mechanism, and the first and second cylinder petals can rotate around the corresponding shafts under human drive, thereby opening or closing with each other.

[0084] See also Figure 7 and Figure 8 As shown, a handle 14 is provided on the first cylinder petal 1 and the second cylinder petal 2 , so that the first cylinder petal 1 and the second cylinder petal 2 can be opened and closed by holding the handle 14 .

[0085] See also Figure 7 and Figure 8 As shown, in order to ensure the structural stability of the first cylinder petal 1 and the second cylinder petal 2 when they are closed, the hot stamping machine includes a lock and assembly, which includes a lifting plate 131, a connecting rod 132 and a limiting plate 133, wherein: the lifting plate 131 is slidably connected to the machine body and is rotatably connected to one end of the connecting rod 132, and the limiting plate 133 is rotatably connected to the second end of the connecting rod 132; the limiting plate 133 is rotatably connected to the machine body, and a slide groove 134 is arranged on the limiting plate 133, and the slide groove 134 includes a card and segment 1341 and a sliding segment 1342, and the card and segment 1341 is connected to the sliding segment 1342. 41 is connected with the sliding section 1342 and has a bending groove structure; the first cylinder petal 1 or the second cylinder petal 2 has a limiting shaft 15 at one end located in the body, and when the first cylinder petal 1 and the second cylinder petal 2 are closed, the limiting shaft 15 is clamped in the clamping section 1341, thereby locking the first cylinder petal 1 or the second cylinder petal 2 to the body; the lifting plate 131 can drive the limiting plate 133 to rotate when an external force pulls upward, so that the limiting shaft 15 enters the sliding section 1342 and moves along the sliding section 1342, thereby unlocking the first cylinder petal 1 or the second cylinder petal 2.

[0086] See also Figure 7 As shown, the limit shaft 15 is clamped in the clamping section 1341, locking the first cylinder petal 1 or the second cylinder petal 2 to the machine body. At this time, the first cylinder petal 1 and the second cylinder petal 2 cannot be opened by the handle 14, preventing the first cylinder petal 1 and the second cylinder petal 2 from opening when the hot stamping machine is working, thereby ensuring the stability of the structure. When the hot stamping is completed and the product needs to be taken out, the lifting plate 131 is lifted upward, and the lifting plate 131 drives the limit plate 133 to rotate through the connecting rod 132, and the limit shaft 15 moves from the clamping section 1341 to the sliding section 1342, and slides along the sliding section 1342. At this time, the first cylinder petal 1 and the second cylinder petal 2 can be opened, making it convenient to take out the product.
