Description

Technical Field

[0001] This application relates to the technical field of printing equipment, and more specifically, to a portable, detachable static eliminator and a printing press. Background Technology

[0002] A gravure printing press is a machine that uses an intaglio printing plate. The image areas of the printing plate are recessed, while the non-image areas are flush with the outer circumference of the printing cylinder. During gravure printing, the substrate (such as plastic film or paper) is prone to generating a large amount of static electricity due to friction at high speeds. Static electricity can lead to a series of quality problems, such as dust adsorbing from the air onto the substrate surface, preventing proper ink transfer and forming tiny blank spots or pinholes. In darker areas, charged ink is attracted to non-image areas, forming fine, thread-like ink splatter. Furthermore, gravure printing uses flammable organic solvents, and the electrical sparks generated during electrostatic discharge can even cause fires if not properly controlled. Therefore, effectively eliminating static electricity during the printing process is crucial.

[0003] The device used to remove static electricity from the substrate is an antistatic bar. In related technologies, the antistatic bar is usually fixed to the main frame of the printing press by permanent bolts or welding. When the antistatic bar needs to be cleaned, the ion needles need to be replaced, or it malfunctions, the disassembly and reinstallation process is cumbersome and time-consuming, which affects production efficiency.

[0004] In conclusion, how to improve the disassembly and maintenance efficiency of static electricity removal devices is a problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0027] The core of this application is to provide a portable, detachable static eliminator and a printing press.

[0028] Please refer to Figure 1 .

[0029] The portable, detachable static eliminator provided in this application includes a static eliminator rod 2. Both ends of the static eliminator rod 2 are detachably connected to connecting mounting parts 3, which connect to the main frame 1. The static eliminator rod 2 connects to an external high-voltage power source and a grounding wire via a quick-connect interface. Discharge needles spaced approximately 5mm apart are evenly distributed on its sidewalls to enhance the static elimination effect. A quick-connect structure 4 is provided between the connecting mounting parts 3 and the static eliminator rod 2. The quick-connect structure 4 allows the static eliminator rod 2 to be easily connected to or disconnected from the connecting mounting parts 3, and keeps them relatively fixed when installed together.

[0030] The aforementioned portable and detachable static eliminator and printing press effectively solve the problem of the complex and inconvenient loading and unloading process of the static eliminator 2 relative to the main frame 1.

[0031] The portable, detachable static eliminator and printing press provided in this application will now be described in more detail with reference to the accompanying drawings and specific embodiments.

[0032] In one specific implementation, reference is made to... Figure 1 .

[0033] Specifically, the connecting mounting part 3 is an L-shaped metal bending part, which includes an integrally formed connecting part 32 and an extension part 31, both of which are straight plates with perpendicular surfaces. The connecting part 32 contacts the main frame 1 and is used to connect and fix it to the main frame 1. The antistatic rod 2 is a slender square rod-shaped object, and the quick-connect structure 4 is located on the extension part 31. The plate surface of the extension part 31 contacts one of the side walls of the antistatic rod 2 and is relatively fixed through the quick-connect structure 4.

[0034] Based on any of the above embodiments, refer to Figure 1 .

[0035] Specifically, the quick-connect structure 4 includes a quick-connect hole 41 and a connecting rod 43. The quick-connect hole 41 is opened on the extension 31, and the connecting rod 43 passes through the antistatic rod 2. The length direction of the connecting rod 43 is perpendicular to the length direction of the antistatic rod 2. The quick-connect hole 41 allows the connecting rod 43 to pass through. When the connecting rod 43 passes through both the antistatic rod 2 and the extension 31 at the same time, the relative positions of the antistatic rod 2 and the connecting mounting part 3 in the length direction of the antistatic rod 2 are fixed.

[0036] like Figure 1 As shown, there are multiple quick-connect holes 41, and the arrangement direction of the multiple quick-connect holes 41 is parallel to the length direction of the antistatic rod 2; that is, by inserting the connecting rod 43 into different quick-connect holes 41, the antistatic rod 2 and the connecting mounting part 3 can maintain different relative positions, so that the longitudinal position of the antistatic rod 2 relative to the connecting mounting part 3 or relative to the main frame 1 can be adjusted, thereby meeting the antistatic needs of printing machines with different widths.

[0037] Based on the above embodiments, refer to Figure 1 .

[0038] Specifically, the quick-connect structure 4 also includes a quick-connect nut 44, and the connecting rod 43 is a bolt. The bolt head is located on the side of the antistatic rod 2 away from the connecting part. The quick-connect nut 44 is located on the side of the extension 31 away from the antistatic rod 2 and is coaxially threaded with the connecting rod 43. The radial dimension of the connecting rod is equal to the diameter of the quick-connect hole 41. Tightening the quick-connect nut 44 fixes the antistatic rod 2 to the connecting mounting part 3.

[0039] In another implementation, such as Figure 2 and Figure 3 As shown.

[0040] The difference from the above embodiment is that, in this embodiment, the extension 31 is further provided with multiple connecting channels 42. The connecting channels 42 connect two adjacent quick-connect holes 41. The diameter of the connecting rod 43 is less than or equal to the width of the connecting channel 42, while the diameter of the quick-connect hole 41 is greater than the width of the connecting channel 42. That is, the connecting rod 43 can move from one quick-connect hole 41 into another quick-connect hole 41 through the connecting channel 42 without axial movement. The quick-connect structure 4 also includes a limiting member for fixing the connecting rod 43 and one of the quick-connect holes 41 coaxially. The limiting member is a limiting washer 45, which is located between the quick-connect nut 44 and the extension 31. The limiting washer 45 allows the connecting rod 43 to pass through coaxially, and the diameter of the limiting washer 45 is greater than the diameter of the quick-connect hole 41.

[0041] like Figure 2 and Figure 3As shown, a limiting protrusion 451 is coaxially fixed to the side of the limiting washer 45 facing the extension 31. The limiting protrusion 451 is inserted into the quick-connect hole 41 and contacts the hole wall of the quick-connect hole 41. Therefore, when the limiting protrusion 451 on the limiting washer 45 through which the connecting rod 43 passes is located in the quick-connect hole 41, the limiting washer 45 cannot move laterally, and the connecting rod 43 cannot move laterally either. Thus, after tightening the quick-connect nut 44, the connecting rod 43 can stably maintain a coaxial relationship with the quick-connect hole 41 where it is located. The function of the limiting washer 45 is to fix the connecting rod 43 and the extension 31 at the same time. If it is necessary to adjust the longitudinal position of the antistatic rod 2 relative to the connecting mounting part 3, it is only necessary to disengage the limiting protrusion 451 from the quick-connect hole 41, without having to completely disengage the quick-connect nut 44 and the connecting rod 43, thereby improving the adjustment efficiency.

[0042] like Figure 3 As shown, in order to make the connecting rod 43 and the limiting pad 45 thereon move more smoothly relative to the extension 31, the surface of the limiting protrusion 451 is a convex spherical surface, and the maximum diameter of the limiting protrusion 451 is greater than or equal to the diameter of the quick-connect hole 41. In this embodiment, the limiting protrusion 451 is a hemisphere, and the diameter of the hemisphere is equal to the diameter of the quick-connect hole 41. When adjusting, since the surface of the limiting protrusion 451 is an arc surface, the process of the limiting pad 45 moving laterally is not easily blocked by the edge of the opening of the quick-connect hole 41.

[0043] Based on any of the above embodiments, such as Figure 1 and Figure 4 As shown.

[0044] Specifically, the connecting mounting component 3 and the main frame 1 are fixed together by magnetic attraction. Therefore, the connecting mounting component 3 is made of magnetic metal, preferably iron in this embodiment. A magnet block 12 is fixedly connected to the main frame 1, and the connecting mounting component 3 will directly contact the magnet block 12. The magnetic connection method has great operational convenience, thereby improving the efficiency of loading and unloading the connecting mounting component 3 relative to the main frame 1.

[0045] like Figure 1 and Figure 4 As shown, a positioning protrusion 11 is fixedly connected to the main frame 1. The end of the positioning protrusion 11 is located on the side of the magnet block 12 facing the antistatic rod 2. A positioning hole 33 is provided on the connecting part 32 for the positioning protrusion 11 to pass through. The number of positioning protrusions 11 and positioning holes 33 is greater than one. In this embodiment, there are two positioning protrusions 11 and six positioning holes 33. The positioning holes 33 are arranged in groups of two, for a total of three groups. Each group of positioning holes 33 allows two positioning protrusions 11 to be inserted. The arrangement direction of the three groups of positioning holes 33 is perpendicular to the length direction of the antistatic rod 2. That is, when the positioning protrusions 11 are inserted into different groups of positioning holes 33, the position of the antistatic rod 2 relative to the main frame 1 can also be adjusted.

[0046] This embodiment also discloses a printing press, such as Figure 1 As shown, the device includes the main frame 1 and the portable, detachable antistatic device. A guide roller 13 is rotatably mounted on the main frame 1, allowing the substrate 14 to pass over it. A magnet 12 is embedded on the surface of the main frame 1 facing the guide roller 13. An antistatic rod 2 is located beside the guide roller 13 and on the side of the substrate 14 away from the guide roller 13. The length of the antistatic rod 2 is parallel to the axis of the guide roller 13. The three sets of positioning holes 33 are arranged radially to the guide roller 13. That is, when the positioning pin 11 is inserted into different positioning holes 33, the distance between the antistatic rod 2 and the substrate 14 is also different, thereby achieving antistatic effects of different intensities.

[0047] The various embodiments in this specification are described in a progressive manner, with each embodiment focusing on the differences from other embodiments. The same or similar parts between the various embodiments can be referred to each other.

[0048] The above provides a detailed description of a portable, detachable static eliminator and printing press provided in this application. Specific examples have been used to illustrate the principles and implementation methods of this application. The descriptions of the embodiments above are merely for the purpose of helping to understand the method and core ideas of this application. It should be noted that those skilled in the art can make various improvements and modifications to this application without departing from its principles, and these improvements and modifications also fall within the protection scope of this application.
