Description

Technical Field

[0001] The utility model relates to the field of printing, in particular to an automatic adjustment photoelectric detection frame structure for an automatic hot stamping die cutting machine. And, an automatic hot stamping die cutting machine having the automatic adjustment photoelectric detection frame structure. Background Art

[0002] A horizontal flat-bed automatic hot stamping die cutting machine with a holographic hot stamping function is as Figure 1 shown. During operation, the printed paper is conveyed to the B main machine unit through the A automatic paper feeding unit, and the hot stamping or die cutting of the printed paper is completed in the B main machine unit. On the left side of the B main machine unit (in the advancing direction Z of the printed paper), an F foil feeding mechanism and an H foil receiving mechanism of the G hot stamping unit are installed. During operation, when the D movable platform moves downward, the printed paper is fed in and positioned to stop between the C fixed platform and the D movable platform. At the same time, the F foil feeding mechanism also unfolds and feeds the holographic aluminized foil into the B main machine unit, and positions and stops between the C fixed platform and the positioned printed paper, and aligns the holographic hot stamping pattern on the holographic aluminized foil with the hot stamping position on the printed paper. As the D movable platform moves upward, it holds the printed paper and the holographic aluminized foil and presses them against the C fixed platform. Under the relative pressure of the D movable platform and the C fixed platform, through the hot stamping die fixedly installed on the C fixed platform, the holographic pattern on the holographic aluminized foil is positioned and hot stamped onto the printed paper. After that, as the D movable platform moves downward again, a new holographic aluminized foil is positioned and fed between the D movable platform and the C fixed platform, while the waste aluminized foil after hot stamping is sent out and returns to the G hot stamping unit from above the C fixed platform through several foil passing rollers, and is rewound and recycled by the H foil receiving mechanism. At the same time, a new printed paper is fed into the B main machine unit and positioned to stop between the D movable platform and the C fixed platform, and the printed paper after hot stamping is sent out of the B main machine unit and enters the J paper receiving unit, and the operation enters the next cycle. During hot stamping, the holographic aluminized foil is always in a tensioned state during the positioning and conveying process.

[0003] According to the different holographic patterns hot stamped on the printed matter, special customized holographic aluminized foils are required, such as Figure 2 shown. Specific holographic patterns are printed on the aluminized foil base tape, and holographic positioning marks are printed corresponding to each holographic pattern. When performing holographic pattern positioning hot stamping on the printed paper, it is necessary to find and capture the holographic positioning marks on the conveyed holographic hot stamping aluminized foil through a photoelectric sensor, and through the signal output when the photoelectric sensor detects the holographic positioning marks, the G hot stamping unit aluminized foil conveying system controls the conveying distance of the holographic aluminized foil, so that the holographic pattern on the holographic aluminized foil is accurately positioned and stopped at the position where the holographic pattern needs to be hot stamped.

[0004] The photoelectric sensor is fixedly installed on the E photoelectric detection frame. Due to the characteristics of the holographic positioning cursor printed on the holographic aluminized foil, during installation, there needs to be an included angle between the axis of the photoelectric sensor and the detection plane of the holographic positioning cursor, and the size of the included angle is determined by the production standard of the holographic aluminized foil. During the initial adjustment of the installation angle and detection position of the photoelectric sensor and the fine adjustment to improve the stamping accuracy of the holographic pattern, it is necessary to adjust the included angle between the axis of the photoelectric sensor and the detection plane of the holographic positioning cursor so that the output signal intensity is as high as possible when the photoelectric sensor detects the holographic positioning cursor, thereby improving the detection sensitivity. By adjusting the front-back position of the photoelectric sensor in the foil feeding direction of the aluminized foil, the stop position of the holographic aluminized foil above the positioned printed paper can be finely adjusted according to the output signal when the photoelectric sensor detects the holographic positioning cursor at the set position, improving the holographic positioning stamping accuracy. According to the different positions of stamping the holographic pattern on different printed papers, it is necessary to correspondingly install a roll of holographic aluminized foil on the F foil feeding mechanism. Generally, when installing the roll of holographic aluminized foil, the E photoelectric detection frame is fixedly installed at a position close to the unfolding and conveying path of the holographic aluminized foil, so that the photoelectric sensor fixedly installed on the E photoelectric detection frame can detect the holographic positioning cursor on the holographic aluminized foil. An E photoelectric detection frame and a photoelectric sensor need to be installed for each roll of holographic aluminized foil. At the same time, during the adjustment process before stamping, it is necessary to manually and continuously finely adjust the front-back position of the photoelectric sensor along the foil feeding direction of the holographic aluminized foil and the included angle with the conveying plane of the holographic aluminized foil. In order to obtain a higher holographic pattern positioning stamping accuracy and the sensitivity to capture the holographic positioning cursor of the holographic aluminized foil.

[0005] Due to the limitation of the installation position of the F foil feeding mechanism of the G stamping unit set, it is very inconvenient to manually finely adjust the front-back position of the photoelectric sensor along the conveying direction of the holographic aluminized foil and the included angle with the conveying plane of the holographic aluminized foil. At the same time, it is also impossible to adjust the accuracy and sensitivity of capturing the holographic positioning cursor during the machine startup operation and during the conveying process of the holographic aluminized foil.

[0027] To solve the above technical problems, the present utility model provides an automatic hot stamping and die cutting machine, which has the structure of the automatic adjustment photoelectric detection frame described in any one of the above.

[0028] The working principle of the present utility model is as follows;

[0029] During operation, the holographic aluminized foil 3-1 slides over the plane on the upper surface of the support rod 3-13 under a certain tension control along the foil feeding direction. When the servo motor II 3-3 drives the screw shaft 3-14 to rotate clockwise or counterclockwise, it can drive the moving bracket 3-6 to move back and forth along the foil feeding direction of the holographic aluminized foil 3-1, and drive the servo motor fixing bracket 3-5 fixedly connected to the moving bracket 3-6 to move in parallel together. The photoelectric sensor 3-12 is fixedly installed on the sensor fixing shaft 3-20 on the servo motor fixing bracket 3-5, thereby realizing the position adjustment of the photoelectric sensor 3-12 in the foil feeding direction of the holographic aluminized foil 3-1.

[0030] When the servo motor I 3-2 drives the sensor fixed shaft 3-20 to rotate clockwise or counterclockwise, it can drive the photoelectric sensor 3-12 installed and fixed on the sensor fixed shaft 3-20 to rotate clockwise or counterclockwise together, so as to realize the adjustment of the angle of the detection plane on the support rod 3-13 by the axis of the photoelectric sensor 3-12 in a plane perpendicular to the conveying direction of the holographic aluminized foil 3-1.

[0031] During the forward conveying process of the holographic aluminized foil 3-1, the photoelectric sensor 3-12 detects the holographic positioning cursor and emits a signal, and the F foil conveying mechanism can control and finely adjust the positioning stop position of the holographic aluminized foil 3-1 between the C fixed platform and the D moving platform according to this signal, so that the holographic pattern is accurately aligned with the hot stamping position on the printed paper.

[0032] During the forward conveying process of the holographic aluminized foil, the fine adjustment of the included angle between the axis of the photoelectric sensor 3-12 and the detection plane on the support rod 3-13 can correct the error in the initial position setting of the detection included angle, and improve the sensitivity and intensity of the output signal.

[0033] The automatic fine adjustment photoelectric sensor 3-12 of the present utility model can automatically fine adjust the position of the photoelectric sensor 3-12 along the front and back of the conveying direction of the holographic aluminized foil 3-1, and can also automatically fine adjust the included angle with the detection plane of the holographic aluminized foil 3-1 on the support rod 3-13 in a plane perpendicular to the conveying direction of the holographic aluminized foil 3-1. At the same time, the above fine adjustment work can be carried out during the startup operation and during the conveying process of the holographic aluminized foil 3-1, without stopping for adjustment, reducing the adjustment time during the holographic pattern positioning hot stamping, and improving the fine adjustment accuracy and work efficiency.

[0068] In addition, it should also be understood that although the terms "first", "second", etc. can be used herein to describe different elements, components, regions, layers and / or parts, these elements, components, regions, layers and / or parts should not be limited by these terms. These terms are only used to distinguish one element, component, region, layer or part from another element, component, region, layer or part. Therefore, without departing from the teachings of the exemplary embodiments of the present utility model, the first element, component, region, layer or part discussed below can also be referred to as the second element, component, region, layer or part.

[0069] For ease of description, spatial relative terms such as "beneath", "above", "lower", "above", "upper", etc. can be used herein to describe the spatial positional relationship of one element or feature to other elements or features as shown in the figures. It should be understood that the spatial relative terms are intended to encompass different orientations in use or operation in addition to the orientation depicted in the figures. For example, if the device in the figures is inverted, the element described as "beneath" or "under" other elements or features will then be positioned "above" or "over" the other elements or features. Thus, the exemplary term "beneath" can include both orientations of "above" and "beneath". The device can also be positioned in other different ways (rotated 90 degrees or in other orientations), and the corresponding explanations are made for the spatial relative descriptors used herein.

[0070] The terms used herein are only for describing specific embodiments and are not intended to limit the exemplary embodiments of the present utility model. As used herein, unless the context clearly indicates otherwise, the singular form is also intended to include the plural form.

In this way, variations in the shapes shown, for example, due to manufacturing techniques and / or tolerances, are expected. Therefore, the exemplary embodiments should not be construed as being limited to the specific shapes of the regions shown herein, but may also include, for example, shape deviations caused by manufacturing. For example, an implantation region shown as rectangular may have rounded or curved features at its edges and / or a gradient change in implantation concentration, rather than just a binary change from the implantation region to the non-implantation region. Similarly, a buried region formed by implantation will result in some implantation also existing in the region between the buried region and the surface through which the implantation passes. Therefore, the regions shown in the figures are substantially schematic, and their shapes are not intended to show the actual shapes of the regions in the device, nor are they intended to limit the scope of the exemplary embodiments according to the present invention.
