DETAILED DESCRIPTION

[0026] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the embodiments described are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without making creative efforts are within the scope of protection of this application.

[0027] In the description of this application, for the convenience of describing this application and simplifying the description, it is not intended to indicate or imply that the device or element referred to must have a specific orientation, be constructed and operate in a specific orientation, and therefore cannot be understood as a limitation of this application. In addition, the terms "first" and "second" are used for descriptive purposes only and cannot be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the said features. In the description of this application, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0028] like Figure 1 、 Figure 2 、 Figure 3 、 Figure 4As shown, a color printing fixing device is provided in an embodiment of the present application, including a positioning base 1, a positioning structure 2 and a rotating pressing device 3.

[0029] The positioning base 1 includes a positioning groove 11, the shape of which is adapted to the shape of the workpiece to be color-printed; the positioning structure 2 includes a plurality of fixed columns 21 arranged around the positioning groove 11; the rotary pressing device 3 includes a rocker arm 31 and an elastic stretching structure 32, the rocker arm 31 is rotatably arranged on one side of the positioning groove 11, one end of the elastic stretching structure 32 is connected to the positioning base 1, and the other end of the elastic stretching structure 32 is connected to the rocker arm 31, and the rocker arm 31 is stretched toward the positioning groove 11 by the elastic stretching structure 32.

[0030] Preferably, the workpiece to be printed is preferably a lighter, and the positioning groove 11 between the positioning structure 2 and the rotating pressing device 3 is the space for accommodating the workpiece to be printed (lighter). The size of the space for accommodating the workpiece to be printed can be adjusted by the rocker arm 31, so that lighters of different volumes can be used, and the lighter can also be accurately fixed. The positioning structure 2 ensures the limiting effect when the workpiece to be printed is placed and rotated, improves the positioning accuracy, and can realize double-sided printing operations. It can reduce the overall volume of the color printing fixing device, so that the volume of the color printing fixing device is not redundant.

[0031] like Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 As shown, in this embodiment, the positioning base 1 is provided with a spring groove 12, and the elastic tensile structure 32 includes a spring 321, which is arranged in the spring groove 12, and the first end of the spring 321 is connected to the end of the spring groove 12, and the second end of the spring 321 is connected to the bottom of the rocker arm 31.

[0032] In this embodiment, the spring groove 12 is located at the edge of the wide side of the positioning groove 11 , and the length of the spring groove 12 is greater than the length of the wide side of the positioning groove 11 .

[0033] In this embodiment, the depth of the spring groove 12 is greater than or equal to the diameter of the spring 321 , and the depth of the positioning groove 11 is greater than the depth of the spring groove 12 .

[0034] like Figure 1 、 Figure 2 、 Figure 3 、 Figure 4As shown, in this embodiment, a first hole 13 and a second hole 14 are respectively provided at both ends of the spring slot 12, and the elastic stretching structure 32 also includes a first spring pin 322 and a second spring pin 323; the first spring pin 322 is fixed in the first hole 13, the first end of the spring 321 is connected to the first spring pin 322, the second spring pin 323 is connected to the bottom of the rocker arm 31, the second end of the spring 321 is connected to the second spring pin 323, and the second hole 14 can accommodate the second spring pin 323.

[0035] The first spring pin 322 is fixed to the positioning base 1 . The first spring pin 322 provides resistance to the spring 321 . When the spring 321 is pulled, the first spring pin 322 provides a reaction force to the spring 321 .

[0036] The function of the first hole 13 is simply to fix the spring 321 so that the spring 321 does not fall off when subjected to tension. The second hole 14 can be provided with a thread, and the function of the second hole 14 is to rotationally fix the second spring pin 323. That is, when the second spring pin 323 is in the second hole 14, it can be fixed in the second hole 14 or rotate in the second hole 14. The lower end of the second spring pin 323 can be threadedly connected to the second hole 14. When the rocker arm 31 rotates, the rotation drives the second spring pin 323 to rotate. The rotation of the second spring pin 323 causes the spring 321 connected to the second spring pin 323 to deform, thereby causing the spring 321 to generate tension. The tension of the spring 321 is transmitted to the second spring pin 323, which acts as resistance to the continued rotation of the rocker arm 31.

[0037] like Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 As shown, in this embodiment, the positioning base 1 is provided with a mounting hole 15, the rotating end of the rocker arm 31 is provided with a through hole 311, and the rotary clamping device 3 also includes a threaded rod 33 and a nut 34. The threaded rod 33 passes through the mounting hole 15 and the through hole 311, and the nut 34 is threadedly connected to the threaded rod 33. The rocker arm 31 rotates with the threaded rod 33 as the center axis.

[0038] In this embodiment, after the nut 34 is threadedly connected to the threaded rod 33 , a gap is provided between the rocker arm 31 and the positioning base 1 ; when the rocker arm 31 abuts against the positioning base 1 , the second spring pin 323 is clamped in the second hole 14 .

[0039] When the through hole 311 is aligned with the mounting hole 15 and connected up and down through the threaded rod 33, the rocker arm 31 can be fixed on the positioning base 1. The threaded rod 33 can rotate in the mounting hole 15, so the rocker arm 31 can perform circular motion around the threaded rod 33 in the mounting hole 15.

[0040] like Figure 1 、 Figure 3 As shown, in this embodiment, the movable end of the rocker arm 31 is provided with a recess 312, which is located on the side facing the spring slot 12. The recess 312 is used to accommodate and limit the movement of the workpiece to be printed, which is placed between the rocker arm 31 and the positioning structure 2. The rocker arm 31 can provide an adjustable placement space for the workpiece to be printed, and the open space of the recess 312 can be adaptively adjusted to a space suitable for the size and extrusion state of the workpiece to be printed, thereby improving the accuracy of the workpiece to be printed on the printing fixture and adapting to workpieces of different sizes. The recess 312 on the rocker arm 31 and the rotation of the rocker arm 31 can provide an adaptive and precise position for the workpiece to be printed, thereby improving the universality and accuracy of the printing fixture for positioning various workpieces to be printed.

[0041] like Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 As shown, in this embodiment, the positioning structure 2 is disposed on the side of the positioning slot 11 where the rotary clamping device 3 is not disposed. The fixing posts 21 are evenly distributed around the positioning slot 11, with gaps formed between the fixing posts 21. The fixing posts 21 are used to define the position of the workpiece to be printed. The gaps between the fixing posts 21 provide space for moving the workpiece to be printed; the fixing posts 21 securely secure the workpiece when it is placed in the receiving space.

[0042] Preferably, multiple printing fixtures are integrally connected, and a control device can be provided to control the movement and rotation of the workpiece to be printed. During the integration of multiple printing fixtures, the fixing posts 21 in two of the fixtures can be shared, thereby reducing the overall volume of the fixtures and maximizing their utilization. The control device controls the movement and rotation of the workpiece to be printed, meaning it can control the placement, placement, and reversal of the workpiece in the vacuum printing system, thereby improving the mechanical automation of lighter printing within the fixture.

[0043] The present application also provides a lighter, which includes a color-printed layer. The color-printed layer is fixedly printed by the color-printing fixing device described above, and a color-printed layer is formed on the surface of the lighter after printing. By placing the lighter on the color-printing fixing device, the lighter is fixed in the limited space between the fixed column 21 and the rocker arm 31 through the limiting effect of the fixed column 21 and the rocker arm 31, and then the exposed side of the lighter is color-printed. After the color printing is completed, the movement and rotation of the lighter is controlled by the control device, the position of the fixed column 21 is adjusted, and the lighter is fixed again in the limited space between the fixed column 21 and the rocker arm 31. The other sides of the lighter are color-printed again, and finally the color printing work on all sides of the lighter is completed, forming a lighter covered with a color-printed layer.

[0044] The present application proposes a color printing fixing device and a lighter, wherein a positioning groove 11 is provided on a positioning base 1 for fixing a workpiece to be color printed, and a positioning structure 2 is provided around the positioning groove 11 to ensure a limiting effect when the workpiece to be color printed is placed and rotated, thereby improving the positioning accuracy and enabling double-sided printing operations. A rotating clamping device 3 is provided on one side of the positioning groove 11 to clamp the workpiece to be color printed, thereby solving the technical problem of inconvenient clamping of the workpiece to be color printed, and the color printing fixing device has a simple structure, which can reduce the volume of the fixing device, and double-sided printing can also improve printing efficiency.

[0045] The technical features of the above embodiments can be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0046] The above-described embodiments merely represent several implementation methods of the present application. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that a person skilled in the art could make various modifications and improvements without departing from the spirit of the present application, all of which fall within the scope of protection of the present application. Therefore, the scope of protection of the present patent application shall be determined by the appended claims.
