[0033] In the description of this application, the terms "one embodiment," "some embodiments," "illustrative embodiment," "example," "specific example," or "some examples," etc., refer to specific features, structures, materials, or characteristics described in connection with that embodiment or example, which are included in at least one embodiment or example of this application. In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example. Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.

[0034] like Figure 1 and Figure 2 As shown in the figure, this application provides a printing apparatus for performing hot stamping operations on cylindrical workpieces.

[0035] The printing device includes a hot stamping head mechanism 100. The structure in the hot stamping head mechanism 100 used to realize hot stamping is a hot stamping head body 102. The hot stamping head body 102 is movably set on the movable support 101 and can be angled on the movable support 101 to adapt to the shape of the workpiece and ensure that the hot stamping head body 102 fits tightly with the workpiece.

[0036] It is understandable that a colored strip is provided on the outside of the workpiece, and the heating head body 102 heats the color on the colored strip to the surface of the workpiece, thereby completing the hot stamping process.

[0037] In some examples, such as Figure 3 and Figure 4 As shown, the ironing mechanism 100 includes a movable support 101, a swing assembly, and an ironing head body 102.

[0038] The swing component is rotatably mounted on the movable support 101. The rotation of the swing component here refers to the rotation of the entire swing component.

[0039] Furthermore, the swing assembly is connected to the heating head body 102, and the heating head body 102 rotates together with the swing assembly, thereby adjusting the angle of the heating head body 102 to adapt to the specific shape of the workpiece.

[0040] In some examples, the swing assembly includes a first swing component 201 and a second swing component 202 that are movably connected. The first swing component 201 is rotatable relative to the movable support 101, and the second swing component 202 is rotatable relative to the first swing component 201. Thus, the swing assembly realizes the movable connection between the movable support 101 and the ironing head body 102, and this movable connection has two degrees of freedom.

[0041] The movable support 101 is provided with a connecting component 203, which is fixedly connected to the movable support 101 and extends to the bottom of the movable support 101.

[0042] Furthermore, the connecting component 203 is rotatably connected to the first swing component 201. The first swing component 201 is located at the bottom of the movable support 101 and is adjacent to the movable support 101, but there is a gap between them, thus leaving space for relative movement.

[0043] Specifically, the second swing component 202 is also rotatably connected to the connecting component 203 and is located at the bottom of the first swing component 201. Thus, the first swing component 201 and the second swing component 202 are rotatably connected through the connecting component 203. In addition, the second swing component 202 is fixedly connected to the ironing head body 102, thereby realizing the angle adjustment of the ironing head body 102.

[0044] In addition, the connecting part 203 is located in the middle of the first swinging part 201, and the connecting part 203 is also located in the middle of the second swinging part 202.

[0045] It is worth noting that the connecting component 203 is connected to the first swing component 201 via two rotating shafts, and the second swing component 202 is also connected to the connecting component 203 via two rotating shafts. The two rotating shafts of the first swing component 201 are coaxial, the two rotating shafts of the second swing component 202 are coaxial, and the rotating shafts of the first swing component 201 and the rotating shafts of the second swing component 202 are approximately perpendicular.

[0046] In some examples, the swing assembly also includes an adjustment component, which is used to adjust the angle of the first swing component 201 relative to the movable support 101 and to adjust the angle of the second swing component 202 relative to the first swing component 201.

[0047] In some examples, the adjustment assembly includes a first adjustment component 204, which is bolted, and a movable bracket 101 is fixedly provided with an adjustment bracket that extends toward the first swing component 201. The adjustment bracket is provided with a threaded hole, and the bolt is threaded into the threaded hole.

[0048] As the bolt is screwed in, the end of the bolt gradually comes into contact with the first swing component 201 and pushes the first swing component 201 to rotate, thereby adjusting the angle of the first swing component 201.

[0049] In some examples, the first swing component 201 and the second swing component 202 are also connected. The first swing component 201 is fixedly provided with a guide component 207, which is a stud.

[0050] The ironing head body 102 is fixedly equipped with an adjusting sleeve 208. The adjusting sleeve 208 has holes inside to make way for the guide components 207. The number of adjusting sleeves 208 is equal to the number of guide components 207, and they correspond one-to-one. Specifically, there are four adjusting sleeves 208 and four guide components 207. The four guide components 207 are respectively inserted into the four adjusting sleeves 208.

[0051] Specifically, the second adjusting component 206 is an adjusting nut, which is threadedly connected to the guide component 207 and located at the middle of the guide component 207 along its length. The adjusting nut abuts against the upper surface of the adjusting sleeve 208. It can be understood that when the second adjusting component 206 rotates, its position changes on the guide component 207.

[0052] When the second adjusting component 206 rotates, it moves along the guide component 207 towards the second swing component 202, thereby pushing the corresponding adjusting sleeve 208, i.e., pushing the second swing component 202. The second swing component 202 then rotates to a corresponding amplitude under the action of the second adjusting component 206, thus achieving angle adjustment of the second swing component 202.

[0053] Since there are four second adjustment components 206 and four guide components 207, and the adjustment effects of the four second adjustment components 206 on the second swing component 202 are different, the second swing component 202 rotates under the combined action of the four second adjustment components 206.

[0054] In some examples, the hair-curling mechanism 100 also includes a frame 103, and a drive assembly 104 is disposed between the frame 103 and the movable support 101, the drive assembly 104 being used to drive the movable support 101 to move.

[0055] The drive assembly 104 includes pulleys and a timing belt. The frame 103 is provided with two pulleys, which are spaced apart and driven by the timing belt. The distance between the two pulleys limits the travel of the moving support 101.

[0056] Furthermore, the movable support 101 is connected to a timing belt. As the pulleys rotate, the timing belt also rotates, thereby driving the movable support 101 to move between the two pulleys.

[0057] In addition, the first swing component 201 is provided with a limiting component 205, and the movable bracket 101 is provided with a guide groove. The limiting component 205 is within the range of the guide groove and forms a certain limiting effect. When the first swing component 201 rotates to the point where the limiting component 205 abuts against the end of the guide groove, the first swing component 201 reaches the rotation limit position.

[0058] In some examples, such as Figure 5 and Figure 6 As shown, the printing apparatus also includes a turntable mechanism 300, which comprises a turntable body 301 and several fixtures 302. Each fixture 302 is formed into a rod-like structure, and its dimensions correspond to the dimensions of the cylindrical workpiece. The cylindrical workpiece is fitted onto the fixture 302. Several air holes are provided on the surface of the fixture 302 to extract gas between the fixture 302 and the workpiece, thereby causing the workpiece to adhere to the fixture 302, thus completing the workpiece loading process.

[0059] Furthermore, tooling 302 is disposed on turntable body 301, and turntable body 301 is provided with a second driver. The second driver is used to drive turntable body 301 to rotate, thereby driving each tooling 302 to rotate.

[0060] The tooling 302 is positioned in a circular pattern on the turntable body 301, specifically, the tooling 302 is evenly distributed. When the turntable body 301 rotates, each tooling 302, together with the workpiece, sequentially reaches the position of the heat exchange head body 102 and sequentially completes the heat exchange process for each workpiece.

[0061] In some examples, the turntable mechanism 300 also includes a plurality of first drivers 303 disposed on the turntable body 301. The first drivers 303 are used to drive the tooling 302 to rotate, thereby causing the workpiece to rotate. It can be understood that the number of first drivers 303 is the same as the number of tooling 302, and they correspond one-to-one.

[0062] Furthermore, a position detection component is provided on one side of the turntable body 301. The position detection component operates by visual detection. When the workpiece rotates with the turntable body 301 to this position, the fixture 302 corresponding to the workpiece rotates under the action of the first driver 303. When the workpiece rotates with the fixture 302 to a specific angle, the workpiece stops rotating, that is, the workpiece is adjusted to the processing state.

[0063] Specifically, the detection object of the position detection component can be a color mark on the side wall of the workpiece.

[0064] Meanwhile, a visual inspection component is provided on the opposite side of the position detection component on the turntable body 301. The visual inspection component is used to detect whether there are defects in the workpiece after hot stamping. It can be understood that the workpiece first rotates to the position detection component for position detection, then rotates to the hot stamping head body 102 for the hot stamping process, and finally rotates to the visual inspection component for visual inspection.

[0065] In some examples, the printing apparatus also includes a take-up and unwind mechanism 400, which includes a take-up assembly and an unwind assembly. The take-up assembly and the unwind assembly are located on opposite sides of the printing head mechanism 100, with the unwind assembly used to release the ribbon and the take-up assembly used to retract the ribbon.

[0066] When the workpiece arrives at the position of the hot stamping head mechanism 100 along with the fixture 302, the fixture 302 drives the workpiece to rotate. At the same time, the unwinding and rewinding of the ribbon also proceeds at the same linear speed. Under these conditions, the hot stamping head body 102 presses the ribbon onto the surface of the workpiece and releases heat at the contact point between the ribbon and the workpiece, thereby completing the hot stamping process.

[0067] In some examples, the unwinding assembly includes an unwinding roller 401 and several first drive rollers 402. The unwinding roller 401 is used to wind the ribbon to be used. As the unwinding roller 401 rotates, the ribbon is gradually discharged from the unwinding roller 401.

[0068] The first drive rollers 402 are spaced apart, and the ribbon that has been guided out of the unwinding roller 401 passes around each of the first drive rollers 402 in sequence, thereby being guided out of the unwinding assembly. It can be understood that each first drive roller 402 defines the guide path of the ribbon, so that there are several bending positions in the guide path of the ribbon.

[0069] Furthermore, the winding assembly includes a winding roller 403 and several second drive rollers 404. The winding roller 403 is used to wind the used ribbon. As the winding roller 403 rotates, the ribbon is wound up and stored in the unwinding roller 401.

[0070] The second drive rollers 404 are spaced apart, and the used ribbon sequentially passes around each of the second drive rollers 404 to be stored in the take-up assembly. It can be understood that each second drive roller 404 defines the ribbon's storage path, so that there are several bending points in the ribbon's storage path.

[0071] In some examples, the unwinding assembly also includes a first tension bar 405, which is rotatable and has a first tension roller 406, which is rotatable. The ribbon led out from each of the first drive rollers 402 reaches the first tension roller 406 and then further reaches the winding assembly.

[0072] Furthermore, the take-up assembly also includes a second tension bar 407, which is rotatable and has a second tension roller 408. The second tension roller 408 is rotatable, and the ribbon led out from the first tension roller 406 extends to the second tension roller 408, and then passes around each of the second drive rollers 404 in sequence from the second tension roller 408, finally reaching the take-up roller 403 to complete the ribbon take-up and unwinding process.

[0073] In actual implementation, the turntable body 301 can simultaneously load several workpieces. Specifically, the turntable body 301 is equipped with eight fixtures 302, which can simultaneously load eight workpieces. The rotation of the turntable body 301 causes one workpiece that has not yet undergone position detection to reach the position detection component, one workpiece that has undergone position detection to reach the bottom of the hot stamping head body 102, and one workpiece that has undergone hot stamping to reach the vision inspection component. Therefore, after the turntable body 301 rotates to a preset position, three workpieces undergo position detection, hot stamping, and vision inspection respectively, and these three processes are performed simultaneously, thereby improving the efficiency of the hot stamping process.

[0074] During the hot stamping process, the ribbon travels from the unwind roller 401 through each of the first drive rollers 402 and the first tension roller 406 to the bottom of the hot stamping head body 102, where it contacts the workpiece. The hot stamping head body 102 heats the ribbon and the workpiece at the bottom. Simultaneously, the unwind roller 401 releases unused ribbon, and the take-up roller 403 collects the used ribbon, causing a change in the relative position between the ribbon and the workpiece. The fixture 302 then rotates the workpiece. The rotation of the fixture 302, in conjunction with the movement of the ribbon, causes the color from the ribbon to adhere to the outer wall of the fixture 302, thus completing the overall hot stamping process.

[0075] In some alternative embodiments, the functions / operations mentioned in the block diagrams may not occur in the order shown in the operation diagrams. For example, depending on the functions / operations involved, two consecutively shown blocks may actually be executed substantially simultaneously, or the blocks may sometimes be executed in reverse order.

[0076] The embodiments of this application have been described in detail above with reference to the accompanying drawings. However, this application is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of this application. Furthermore, unless otherwise specified, the embodiments and features described in the embodiments of this application can be combined with each other.
