Description

Technical Field

[0001] This utility model relates to the field of static electricity elimination technology in inkjet printing, and in particular to a static electricity elimination device for inkjet printers. Background Technology

[0002] With the advancement of technology, the advertising and printing industry has developed rapidly, leading to the increasingly widespread application of photo printers and inkjet printers. Photo printers are mainly used for producing indoor promotional materials such as stickers, display boards, posters, and regulations. When using them, the biggest hazard of static electricity to inkjet printers is the droplet phenomenon, where tiny droplets of ink ejected from the printhead fly around randomly under the interference of static electricity. This has the following effects: first, inaccurate color injection, resulting in poor print quality; second, clogging of the printhead, affecting the lifespan of the expensive printhead.

[0003] Utility model CN219834442U discloses an electrostatic elimination device for inkjet printers, including a fixing plate. A placement box is fixedly installed on the top of the fixing plate. Two symmetrically distributed connecting plates are fixedly installed through the fixing plate. A common base plate is fixedly installed at the bottom of the two connecting plates. A discharge needle array for discharging to eliminate static electricity is fixedly installed at the bottom of the base plate. A power supply mechanism for supplying high voltage to the discharge needle array is provided inside the placement box. The power supply mechanism includes a high voltage generator fixedly installed inside the placement box. This utility model relates to the field of inkjet printer technology. This electrostatic elimination device for inkjet printers compresses the installation space by compactly installing the discharge needle array and the high voltage generator together to form a whole, thus making it easy to install on the left and right ends of the carriage inside the inkjet printer. It has a compact structure and is convenient to use.

[0004] The device disclosed in the above-mentioned utility model is relatively complex in its setup, occupies a large space, and is inconvenient for later maintenance. Utility Model Content

[0005] The purpose of this utility model is to provide an electrostatic elimination device for inkjet printers, so as to solve the problems mentioned in the background art, such as complex setup, large space occupation, and inconvenience for later maintenance.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a static eliminator for a large-format printer, comprising a printing head, with U-shaped connecting plates installed on both sides of the printing head, and static eliminators movably connected within each of the two U-shaped connecting plates. A first connecting plate is installed on the static eliminator, the first connecting plate being located inside the U-shaped connecting plates. A plurality of connecting holes are opened on one side of the U-shaped connecting plate, and a movable shaft is slidably connected within each of the plurality of connecting holes. A first clamping block is installed at the end of each of the plurality of movable shafts near the static eliminator, the first clamping block being in contact with the static eliminator. A first spring is sleeved on each of the plurality of movable shafts, the first spring being located between the first clamping block and the inner wall surface of the U-shaped connecting plate.

[0007] Preferably, a second clamping block is provided on each side of the two U-shaped connecting plates that are close to each other, and a second spring is connected to the second clamping block. The second spring is connected to the inner side wall of the U-shaped connecting plate.

[0008] Preferably, the inner sides of both U-shaped connecting plates are provided with receiving grooves, and the first clamping block or the second clamping block on the same side can be slidably adapted into the corresponding receiving groove.

[0009] Preferably, the U-shaped connecting plate has several grooves on both sides, and the first spring and the second spring are slidably adapted to the corresponding grooves. The ends of the several second springs away from the second clamping block are connected to the inner wall of the corresponding groove.

[0010] Preferably, rubber pads are installed on the side of several of the first clamping blocks and the second clamping blocks that are close to the static eliminator.

[0011] Preferably, each of the two U-shaped connecting plates is movably connected to a mounting plate on the side away from each other, and a scraper is installed on the bottom of the mounting plate, with a sponge pad movably disposed on the scraper.

[0012] Preferably, the scraper has a connecting groove, and a connecting block is installed on the sponge pad, with the connecting block slidingly fitted into the connecting groove.

[0013] The beneficial effects of this utility model are:

[0014] In this invention, by pushing the static eliminator into the U-shaped connecting plate, the first connecting plate on the static eliminator moves synchronously into the U-shaped connecting plate. During the movement, the first connecting plate first contacts several first clamping blocks, and through an upward thrust, pushes the several first clamping blocks outward from the U-shaped connecting plate. When the first connecting plate moves above the several first clamping blocks, the first spring automatically resets, thereby generating a thrust to push the first clamping blocks towards the static eliminator and into contact with it. Thus, the first clamping blocks constrain the static eliminator, allowing it to be securely connected to the printing head. When the printing head moves, it can drive the static eliminators installed on both sides of it to move synchronously. Thus, the static eliminators first eliminate static electricity on the printing paper, and then the printing head performs printing, thereby avoiding ink splatter and affecting the printing quality. This device has a simple structure and occupies a small area. It can perform pre-demagnetization operations in both directions when the printing head moves back and forth, effectively improving work efficiency. Furthermore, the movable installation method of the two static eliminators facilitates later maintenance. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] Reference Figure 1-5 An electrostatic elimination device for a large-format printer includes a printing head 1. U-shaped connecting plates 2 are installed on both sides of the printing head 1. An electrostatic eliminator 3 is movably connected within each of the two U-shaped connecting plates 2. A first connecting plate 4 is installed on the electrostatic eliminator 3, located inside the U-shaped connecting plates 2. Several connecting holes 5 are opened on one side of the U-shaped connecting plates 2. Moving shafts 6 are slidably connected within each of the connecting holes 5. A first clamping block 7 is installed at the end of each moving shaft 6 near the electrostatic eliminator 3, and the first clamping block 7 contacts the electrostatic eliminator 3. A first spring 8 is sleeved on each of the moving shafts 6, and the first spring 8 is located between the first clamping block 7 and the inner wall of the U-shaped connecting plate 2.

[0023] When static electricity needs to be eliminated from the inkjet paper, the user pushes the static eliminator 3 into the U-shaped connecting plate 2, causing the first connecting plate 4 on the static eliminator 3 to move synchronously into the U-shaped connecting plate 2. During this movement, the first connecting plate 4 first contacts several first clamping blocks 7, and pushes these first clamping blocks 7 outwards through an upward thrust. When the first connecting plate 4 moves above the several first clamping blocks 7, the first spring 8 automatically resets, thereby generating a thrust to move the first clamping blocks 7 towards the static eliminator 3 and into contact with it, thus eliminating static electricity through the first clamping blocks 7. The static eliminator 3 is positioned to ensure a stable connection to the printing head 1. When the printing head 1 moves, it drives the static eliminators 3 installed on both sides to move synchronously. This allows the static eliminators 3 to eliminate static electricity on the printing paper before the printing head 1 performs printing, thus preventing ink splatter and affecting the printing quality. The device has a simple structure and occupies a small area. It can perform pre-demagnetization operations in both directions when the printing head 1 moves back and forth, effectively improving work efficiency. Furthermore, the movable installation method of the two static eliminators 3 facilitates later maintenance.

[0024] Specifically, in this embodiment, a second clamping block 9 is provided on the side of the two U-shaped connecting plates 2 that are close to each other. A second spring 10 is connected to the second clamping block 9. The second spring 10 is connected to the inner side wall of the U-shaped connecting plate 2, so that the end of the static eliminator 3 away from the first clamping block 7 can be limited by the second clamping block 9 driven by the second spring 10, thereby further improving the connection stability of the static eliminator 3.

[0025] Specifically, in this embodiment, the inner sides of the two U-shaped connecting plates 2 are provided with receiving grooves 11. The first clamping block 7 or the second clamping block 9 on the same side can be slidably adapted to the corresponding receiving groove 11, so that when the first connecting plate 4 pushes the first clamping block 7 and the second clamping block 9 to both sides, the first clamping block 7 or the second clamping block 9 can be slidably adapted to the receiving groove 11, thereby providing space for the movement of the first clamping block 7 and the second clamping block 9.

[0026] Specifically, in this embodiment, several grooves 12 are provided on both sides of the U-shaped connecting plate 2. The first spring 8 and the second spring 10 are respectively slidably adapted in the corresponding grooves 12. The ends of several second springs 10 away from the second clamping block 9 are connected to the inner wall surface of the corresponding grooves 12, so that the first spring 8 and the second spring 10 can slide in the corresponding grooves 12, thereby compressing the first spring 8 and the second spring 10 in the corresponding grooves 12 and resetting them in the grooves 12. Thus, the grooves 12 provide a guarantee for the movement state of the first spring 8 and the second spring 10.

[0027] Specifically, in this embodiment, rubber pads 13 are installed on the side of several first clamping blocks 7 and second clamping blocks 9 near the static eliminator 3. When the first clamping blocks 7 and second clamping blocks 9 move toward the static eliminator 3, the rubber pads 13 will first come into contact with the static eliminator 3, thereby further increasing the friction between the first clamping blocks 7, second clamping blocks 9 and the static eliminator 3, making the installation of the static eliminator 3 more stable, and at the same time, the rubber pads 13 provide protection for the static eliminator 3.

[0028] Specifically, in this embodiment, mounting plates 14 are movably connected to the two U-shaped connecting plates 2 on opposite sides. A scraper 15 is installed at the bottom of the mounting plate 14, and a sponge pad 16 is movably disposed on the scraper 15, so that the scraper 15 can be movably disposed on the printing head 1. When there is dust on the surface of the carrier to be printed, the scraper 15 and the sponge pad 16 can be moved synchronously by the movement of the printing head 1, thereby achieving the purpose of removing the dust from the surface of the printing carrier and further improving the practicality of the device.

[0029] Specifically, in this embodiment, a connecting groove 17 is provided on the scraper 15, and a connecting block 18 is installed on the sponge pad 16. The connecting block 18 is slidably adapted to the connecting groove 17, so that the sponge pad 16 can be slidably connected to the scraper 15 through the compatibility between the connecting block 18 and the connecting groove 17, thereby facilitating the replacement and cleaning of the sponge pad 16.

[0030] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
