Description

Technical Field

[0001] The present invention relates to the technical field of printers, and in particular to a ribbon box, a label printer and an installation method. Background Art

[0002] A label printer is a professional device used to print barcodes, QR codes, text and other label information. It is usually small in size, easy to carry, and can quickly generate various types of labels. It does not need to be connected to a computer, and it carries its own input keyboard or uses a smart touch screen for operation. It has built-in multiple fonts, character libraries and a large number of label template formats. It can directly input, edit, layout and print label content through the LCD screen of the machine. It has a wide range of application scenarios, covering many places such as homes, offices, factories, warehouses, shopping malls, etc. It can be used to print clothing tags, train tickets, boarding passes, luggage tags, product labels, etc.

[0003] The Chinese patent with the announcement number "CN209756504U" discloses a ribbon cartridge and a label printer, which includes a housing, a first accommodating area, a tape outlet, a tape outlet passage and a first guide. By arranging the first guide in the ribbon cartridge, under the guiding action of the first guide, since the print medium tape can contact part of the inner wall of the tape outlet passage in the tape outlet passage, there is friction between the print medium tape and the inner wall in contact with it, so that the ribbon cartridge can provide a stable tape outlet force for the print medium tape in an idle state or a working state, thereby improving the rewinding tendency of the print medium tape;

[0004] Although the above-mentioned device has shown convenience to a certain extent during actual use, it has obvious defects and shortcomings in the specific use process. The display screen and keyboard parts of the device are directly exposed to the outside, and face many risks during use and carrying. On the one hand, if the printer accidentally falls or during storage, due to the lack of effective protection measures, the display screen is very likely to be hit or scratched, which may cause damage to the display screen and affect its normal display function. On the other hand, during the carrying process, the keyboard part is also prone to being pressed by mistake. This mispressing situation may cause a series of problems, such as causing printer malfunction or accidental printing, which not only wastes paper and consumables, but also may interfere with the workflow. It can be seen that under the current design, the overall use of the device does have certain defects and shortcomings, and it is urgently needed to improve the design to improve its safety and reliability.

[0012] Furthermore, the limiting block is in the shape of an elongated oval in top view, the clamping frame is in the shape of an arc, and one end of the connecting shaft away from the limiting block is fixedly connected to a bridge-type handrail.

[0013] Furthermore, the cleaning component includes a guide rail, which is fixedly installed on a side of the mounting plate close to the printer body. A slide plate is slidably connected to the inside of the guide rail, and a rubber scraper is fixedly connected to the side of the slide plate close to the printer body. The bottom of the rubber scraper is fit-connected to the outer surface of the display screen, and limit plates are fixedly installed on both sides of the interior of the frame, and the limit plates are arranged at both ends of the slide plate.

[0014] Furthermore, the limiting mechanism includes a circular hole and a concave card plate, the circular hole is opened at the upper end of the front side of the printer body, a telescopic spring is fixedly connected to the inside of the circular hole, a front end of the telescopic spring is fixedly connected to a limiting rod, the concave card plate is fixedly connected to the middle of the top of the flip cover, the end of the limiting rod is inserted into the inner middle part of the concave card plate, and the outer end of the limiting rod is arranged in a circular arc shape as a whole.

[0015] A method for installing a label printer comprises the following steps:

[0016] Step 1: Open the ribbon box cover. When you need to open the ribbon box, press the L-shaped elastic hook plate. The elastic hook plate is made of spring steel and has a certain elastic force. It is stably hooked on the box cover during use. Press the elastic hook plate to deform it, and then adjust the elastic hook plate to rotate inside the hinge slot. At this time, you can easily open the box cover to prepare for replacing the ribbon.

[0017] Step 2: Install the ribbon and close the box cover. After installing the new ribbon into the box body, put the box cover back on the box body and then connect it to the box cover through the elastic hook plate. In this way, the box cover and the box body are stably installed. Then the box body can be placed inside the cavity of the printer.

[0018] Step 3: Fix the flip cover, put the box body into the cavity, and cover the front side of the cavity. At this time, the telescopic spring is reset to push the limit rod outward. When the flip cover is covered, the concave card plate is located on the outside of the limit rod. The limit rod is pushed outward by the telescopic spring reset, and the limit cover can be clamped inside the concave card plate, so that the flip cover is stably clamped on the top of the box body;

[0019] Step 4: Protect the display screen and keyboard. When using and carrying the device, you can adjust the cover plate to slide on the inside of the square groove and cover the outside of the square groove. After the cover plate covers the outside of the square groove, it can help protect the outside of the display screen and the control keyboard to prevent the control keyboard and display screen from being scratched, hit or pressed by mistake.

[0020] Step 5: Clean the display screen. If you need to operate the display screen, you can pull the cover plate downwards by pulling out the bridge-type handrail. The cover plate will move downwards after being pulled. The downward movement of the cover plate can drive the rubber scraper to scrape the outer surface of the display screen, which can help clean the display screen. Each time you open and close the cover plate, you can clean the display screen.

[0021] Step 6: Replace the rubber scraper. During use, if the rubber scraper needs to be replaced, you can push the bridge armrest. At this time, the substrate can move toward the printer body, and the limit spring shrinks. As the substrate moves closer to the printer body, the limit block can be detached from the inner side of the card frame. By rotating the bridge armrest, the elliptical limit block changes from longitudinal to transverse. At this time, the two ends of the limit block are detached from the card frame, and then the substrate, elastic member and cleaning member inside the frame can be pulled out from the inside of the frame. After pulling out the cleaning member, pull out the slide plate inside the guide rail, then take out the slide plate with a new rubber scraper and insert it into the inside of the guide rail, and then reinsert the elastic member and cleaning member into the inner side of the frame. By pressing the substrate, the substrate squeezes the limit spring to shrink and cross the card frame. At this time, twist the bridge armrest longitudinally, and the limit spring moves outward to drive the two ends of the limit block to be inserted into the inside of the card frame. The limit block and the card frame are mutually limited to complete the installation of the cleaning member and the elastic member, which is convenient for replacing the rubber scraper.

[0022] Compared with the prior art, the present invention has the following beneficial effects:

[0023] First, in the present invention, the device is provided with a box body and a limiting mechanism, so that when it is necessary to open the ribbon box, the L-shaped elastic hook plate is pulled, and the hook plate is made of spring steel and has good elasticity, and can be stably hooked on the box cover. If the box cover is to be opened, it is only necessary to pull the elastic hook plate to deform it, and then rotate it in the hinge groove. After installing the ribbon, the box cover is covered on the box body again, and the elastic hook plate is clamped and fixed again. Then, the box body can be placed in the cavity. When the flip cover covers the front side of the cavity, the telescopic spring will reset and push the limiting rod to move outward. At this time, if the flip cover is covered in place, the concave card plate will be located outside the limiting rod, and the limiting rod and the concave card plate will be clamped with each other, so as to stably fix the flip cover just above the box body. When opening the flip cover, it is only necessary to press the limiting rod, and its end is designed in a circular arc shape. After pressing, the telescopic spring will be squeezed to contract, so that the limiting rod is retracted into the round hole, which is convenient for operation. This design makes the disassembly, assembly and placement of the ribbon box extremely convenient, and improves the use efficiency of the printer.

[0024] Secondly, in the present invention, the printer also has an excellent design in terms of protection and cleaning of the display screen and the control keyboard. By setting an elastic cleaning component, the cover plate can be adjusted to slide in the square groove and cover the outside of the square groove, thereby protecting the display screen and the control keyboard. During use and carrying, the cover plate can effectively prevent the display screen and the control keyboard from being scratched, hit or pressed by mistake. When the cover plate is covered, the limit spring will reset and push the mounting plate close to the printer body, so that the rubber scraper fits the inside of the square groove, and presses the cover plate in the opposite direction through the elastic force to ensure that it stably covers the outside of the display screen. When operating the display screen, the bridge armrest can be pulled out to pull the cover plate downward. The downward movement of the cover plate will drive the rubber scraper to scratch the outer surface of the display screen to play a cleaning role. If the rubber scraper needs to be replaced, the bridge armrest is pushed to make the base plate close to the printer body, the limit spring contracts, the limit block is separated from the card frame, and the bridge armrest is rotated to change the limit block from longitudinal to lateral, and the cleaning component can be pulled out for replacement.

[0025] Thirdly, in the present invention, the convenient disassembly and assembly design of the ribbon cassette saves time and energy in replacing the ribbon. The user does not need to look for tools or perform complicated operations. The user only needs to simply pull the elastic hook plate and the operating limit rod to easily complete the installation and disassembly of the ribbon cassette. This improves work efficiency for users who often need to replace the ribbon. In terms of protection of the display screen and the control keyboard, the presence of the cover plate effectively prevents them from being scratched, hit or pressed accidentally during use and carrying, which extends the service life of the printer and reduces the maintenance cost caused by accidental damage. At the same time, the cleaning function of the rubber scraper on the display screen ensures that the user can have a clear visual experience every time it uses it, and the operation and viewing of information will not be affected by stains on the screen. The design of convenient replacement of the rubber scraper allows users to update the cleaning components in time according to actual conditions to keep the printer in good condition.

[0040] A method for installing a label printer comprises the following steps:

[0041] Step 1: Open the ribbon box cover 3. When the ribbon box needs to be opened, press the elastic hook plate 5 arranged in an L shape. The elastic hook plate 5 is made of spring steel and has a certain elastic force. It is stably hooked on the box cover 3 of the box body 1 during use. Press the elastic hook plate 5 to deform it, and then adjust the elastic hook plate 5 to rotate inside the hinge slot 4. At this time, the box cover 3 can be easily opened to prepare for replacing the ribbon.

[0042] Step 2: Install the ribbon and close the box cover 3. After installing the new ribbon into the box body 1, put the box cover 3 back on the box body 1 and then snap it onto the box cover 3 through the elastic hook plate 5. In this way, the box cover 3 and the box body 1 are stably installed. Then the box body 1 can be placed inside the cavity 7 of the printer.

[0043] Step 3: Fix the flip cover 8, put the box body 1 into the cavity 7, and then cover the flip cover 8 to the front side of the cavity 7. At this time, the telescopic spring 93 is reset to push the limit rod 94 outward. When the flip cover 8 is covered, the concave card plate 92 is located on the outside of the limit rod 94. The limit rod 94 is pushed outward by the telescopic spring 93 being reset, and the limit cover can be clamped inside the concave card plate 92, so that the flip cover 8 is stably clamped just above the box body 1.

[0044] Step 4: Protect the display screen 14 and keyboard. When using and carrying the device, the cover plate 114 can be adjusted to slide on the inner side of the square groove 10, and the cover plate 114 can cover the outer side of the square groove 10. After the cover plate 114 covers the outer side of the square groove 10, the outer side of the display screen 14 and the control keyboard 13 can be protected to prevent the control keyboard 13 and the display screen 14 from being scratched, hit or pressed by mistake.

[0045] Step 5: Cleaning the display screen 14. If the display screen 14 needs to be operated, the cover plate 114 can be pulled downward by pulling out the bridge-type handrail 11344. The cover plate 114 moves downward after being pulled. The downward movement of the cover plate 114 can drive the rubber scraper 11333 to scrape the outer surface of the display screen 14, which can assist in cleaning the display screen 14. The display screen 14 can be cleaned each time the cover plate 114 is opened and closed;

[0046] Step 6: Replace the rubber scraper 11333. During use, if the rubber scraper 11333 needs to be replaced, the bridge armrest 11344 can be pushed.

The limit block 11343 and the card frame 11341 limit each other to complete the installation of the cleaning member 1133 and the elastic member 1132, so that the rubber scraper 11333 can be replaced conveniently.

[0047] The working principle of the present invention is as follows: by arranging the box body 1 and the limiting mechanism 9, if the ribbon box needs to be opened during use of the device, the elastic hook plate 5 arranged in an L shape can be pressed. The elastic hook plate 5 is made of spring steel and has a certain elastic force. It can stably hook on the box cover 3 of the box body 1 during use. When it is necessary to open the box cover 3, it is only necessary to press the elastic hook plate 5 to deform it, and then adjust the elastic hook plate 5 to rotate inside the hinge groove 4, so that the box cover 3 can be easily opened to replace the ribbon. After the ribbon is installed, the box cover 3 is covered on the box body 1 again, and then the box cover 3 is snapped onto the elastic hook plate 5, so that the box cover 3 and the box body 1 can be stably installed. After the box cover 3 and the box body 1 are installed, the box body 1 can be placed inside the cavity 7, and then the flip cover 8 is covered to the front side of the cavity 7. At this time, the telescopic spring 93 is reset to push the limiting rod 94 to move outward. When the flip cover 8 is covered, the concave card plate 92 The outer side of the limit rod 94 is located, and the limit rod 94 is pushed outward by the telescopic spring 93 to move back, so that the limit cover can be clamped in the inside of the concave card plate 92. The limit rod 94 and the concave card plate 92 are clamped with each other, and the flip cover 8 can be stably clamped in the top of the box body 1. If it is necessary to open the flip cover 8, the limit rod 94 can be pressed. The end of the limit rod 94 is set in an arc shape. When the limit rod 94 is pressed, the telescopic spring 93 is squeezed and contracted, and the limit rod 94 is retracted into the inside of the circular hole 91. Since the end of the limit rod 94 is arc-shaped, when its arc surface contacts the bottom of the concave card plate 92, the concave card plate 92 can be turned over, and the concave card plate 92 further squeezes the end arc surface of the limit rod 94, prompting the limit rod 94 to further contract into the inside of the circular hole 91, thereby conveniently and quickly opening the cavity 7. It can be seen that the printer is extremely convenient in the disassembly and placement of the ribbon cassette, which can significantly improve the convenience of the overall use of the device;

[0048] By setting the protection mechanism 11, the device can be used to adjust the cover plate 114 to slide on the inner side of the square groove 10, so that the cover plate 114 covers the outer side of the square groove 10.

During the use and carrying process, the cover plate 114 covers the outer side of the display screen 14, which can effectively protect the display screen 14 and the control keyboard 13. During the covering period of the cover plate 114, the limit spring 11322 is reset, pushing the installation plate 11323 to move close to the printer body 6. At this time, the installation plate 11323 pushes the rubber scraper 11333 to fit the inside of the square groove 10, and reversely presses the cover plate 114 through the elastic force, so that The cover plate 114 can stably cover the outer side of the display screen 14. During use, the cover plate 114 can protect the control keyboard 13 and the display screen 14 to prevent the control keyboard 13 and the display screen 14 from being scratched, hit or pressed by mistake, thereby improving the stability and convenience of the overall use of the device. If it is necessary to operate the display screen 14, the cover plate 114 can be pulled downward by pulling out the bridge-type handrail 11344. After the cover plate 114 is pulled, it moves downward. The downward movement of the cover plate 114 can drive the rubber scraper 11333 to scrape the outer surface of the display screen 14, which can assist in cleaning the display screen 14, so that the display screen 14 can be cleaned each time the cover plate 114 is opened and closed. During use, if more To replace the rubber scraper 11333, you can push the bridge armrest 11344. At this time, the substrate 11321 can move toward the printer body 6, and the limit spring 11322 will shrink. As the substrate 11321 moves closer to the printer body 6, the limit block 11343 can be detached from the inner side of the card frame 11341. By rotating the bridge armrest 11344, the elliptical limit block 11343 changes from longitudinal to transverse. At this time, the two ends of the limit block 11343 are detached from the card frame 11341, and then the substrate 11321, the elastic member 1132 and the cleaning member 1133 inside the frame 1131 can be pulled out from the inside of the frame 1131. After the cleaning member 1133 is pulled out, the slide plate 11332 inside the guide rail 11331 can be pulled out. When the sliding plate 11332 with the new rubber scraper 11333 is taken out, it is inserted into the guide rail 11331, and the elastic member 1132 and the cleaning member 1133 are reinserted into the inner side of the frame 1131, and the base plate 11321 is pressed to cause the base plate 11321 to squeeze the limit spring 11322 to contract and pass over the card frame 11341. At this time, the bridge handrail 11344 is twisted longitudinally, and the limit spring 11322 moves outward to drive the two ends of the limit block 11343 to be inserted into the interior of the card frame 11341. The limit block 11343 and the card frame 11341 are mutually limited, and then the cleaning member 1133 and the elastic member 1132 can be installed, so that the cleaning member 1133 and the limit member 1134 can be quickly disassembled and replaced as a whole.The rubber scraper 11333 can be easily replaced, which can greatly improve the convenience of the overall use of the device.
