Description

Technical Field

[0001] This invention relates to the field of label printing technology, specifically to a reverse label support printer. Background Technology

[0002] Label printers are printers that do not require a computer connection, have built-in fonts, character sets, and a considerable number of label template formats, and allow users to directly input, edit, and format label content according to their needs before printing. They are widely used in many places such as offices, factories, warehouses, and shopping malls.

[0003] Existing technologies disclose several invention patents in the field of printer technology. Among them, patent application number CN219076857U discloses a label printer, including a printer body with a base fixed to its bottom. A first and second movable doors are movably arranged on one side of the base. The printer also includes: a suction mechanism installed inside the base, with one end extending outside the base; and a conveying mechanism installed inside the base, on which a label roll is movably mounted. This invention's label printer features a suction mechanism that can magnetically attach the base and printer body to the mounting position, freeing the user's hands and facilitating printer operation. The conveying mechanism, in conjunction with the first movable door, can hold the label roll within the first movable door, making it easy for the user to retrieve it, thus improving the label printer's efficiency and practicality.

[0004] When using the traditional labels, users have to peel them off from the printer's base plate and then stick them on, which is inefficient and prone to tearing and misalignment. This makes it difficult to peel off and re-stick some labels after they have been misaligned.

[0005] Based on this, the present invention designs a reverse label support printer to solve the above problems. Summary of the Invention

[0006] The purpose of this invention is to provide a reverse label support printer to solve the problem mentioned in the background art that labels are easily torn and misaligned.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a reverse label support printer, comprising a lower body, an upper body, a suction mechanism, a scraper mechanism, a paper roller, a limiting mechanism, a paper jam mechanism, a sensor, a print head, a conveying mechanism, a take-up roller, and a second motor. The upper body and the lower body are rotatably connected together. A paper outlet is provided at the front end where the lower body and the upper body meet. A suction mechanism is movably provided at the paper outlet of the upper body. The suction mechanism includes a roller, axle, connecting posts, a silicone suction cup, a fixing post, and a pressure spring. The axle is symmetrically fixedly connected to both ends of the roller. Multiple connecting posts are fixedly and annularly distributed on the side of the roller. A silicone suction cup is fixedly connected to each connecting post. The silicone suction cup is made of a wear-resistant silicone material. The fixing posts are annularly distributed below the silicone suction cup and fixedly connected to the roller. One end of the pressure spring is fixedly connected to the silicone suction cup, and the other end is fixedly connected to the fixing post.

[0008] The rollers are equipped with multiple silicone suction cups, which adsorb the label paper base plate. The label paper is then scraped off the label paper base plate by a scraper mechanism, thus achieving the scraping and pasting of the label through the rotation of the adsorption mechanism.

[0009] As a further embodiment of the present invention, a scraper mechanism is provided at the paper outlet at the front end of the upper body. The scraper mechanism includes a scraper blade, a limiting block, a screw, a turning handle, a spring, a limiting plate, a bidirectional lead screw, a sliding limiting baffle, and a turning head. The limiting block is symmetrically arranged on the scraper blade, the screw is threadedly connected to the center of the scraper blade, the turning handle is fixedly connected to one end of the screw, and the spring is symmetrically fixedly connected to the inner side of the scraper blade.

[0010] The sliding limit baffle of the scraper mechanism can limit the two sides of the scraped label paper, making it less likely to be pasted crookedly, thus achieving a better pasting effect.

[0011] As a further embodiment of the present invention, the limiting plates are symmetrically fixedly connected to the outside of the scraper, the outside of the scraper is provided with a sliding groove, the two ends of the bidirectional screw are movably installed in the two limiting plates, the screw head is fixedly connected to one end of the bidirectional screw, and the two sliding limiting baffles are threadedly connected to the bidirectional screw.

[0012] By using sliding limiters to restrict the scraper machines at both ends, a good positioning effect can be achieved, resulting in a good pasting effect.

[0013] As a further embodiment of the present invention, a slider is fixedly connected to the sliding limit baffle, and the sliding limit baffle is movably connected to the slide groove through the slider.

[0014] By observing the two sliding limit baffles, the neatness of the pasting can be detected, which facilitates the pasting of the label.

[0015] As a further embodiment of the present invention, a paper roller is provided inside the lower body, and a limiting mechanism is provided in front of the paper roller. The limiting mechanism includes a wheel, a retaining ring, a compression spring, a threaded rod, and a rotating rod. The upper end of the compression spring is fixedly connected to the retaining ring, and the lower end of the compression spring is fixedly connected inside the lower body. The retaining ring is provided with a wheel, and the upper part of the retaining ring abuts against the threaded rod. The threaded rod is threadedly connected inside the lower body, and the rotating rod is fixedly connected to the upper end of the threaded rod.

[0016] By screwing the screw rod into the lower body, the retaining ring is pressed downwards, thereby adjusting the tension of the label paper.

[0017] As a further embodiment of the present invention, a paper jamming mechanism is provided in front of the limiting mechanism, a sensor is provided on the paper jamming mechanism, and a conveying mechanism is provided in front of the paper jamming mechanism.

[0018] By setting up sensors, the coordination between the conveying mechanism and the paper jam mechanism can be detected, which can better assist staff in monitoring.

[0019] As a further embodiment of the present invention, the conveying mechanism includes a rolling wheel, a limiting end, a first gear, a second gear, and a first motor. The limiting end is disposed on the lower body of the machine. The right end of the rolling wheel is movably installed inside the limiting end. The first gear is fixedly connected to the left end of the rolling wheel. The second gear meshes with the first gear. The output shaft of the first motor is fixedly connected to the second gear. The first motor is fixedly installed inside the lower body.

[0020] The transmission connection between various gears makes it more suitable for connecting conveyor mechanisms, while the setting of the limiting end makes it more suitable for the downward movement of the wheel.

[0021] As a further embodiment of the present invention, the print head is located at the center above the paper jam mechanism, the print head is fixedly connected to the inside of the upper body, the take-up roller is movably installed inside the upper body, the output end of the second motor is fixedly connected to one end of the take-up roller, and the second motor is fixedly connected to one side of the upper body.

[0022] The label paper base plate is fixed to the winding roller by winding it upwards from the bottom of the adsorption mechanism, thus completing the installation of the label paper and making it more suitable for the adsorption structure.

[0023] As a further embodiment of the present invention, the front end of the upper body is provided with a square groove, a mounting groove and a threaded groove, the limiting block is slidably disposed in the square groove, the screw is threadedly connected in the threaded groove, and the elastic spring is fixedly connected in the mounting groove.

[0024] The use of sliding limit blocks and square grooves prevents wrinkles from forming during transport.

[0025] Compared with the prior art, the beneficial effects of the present invention are: 1. This invention utilizes an adsorption mechanism. During use, the rotation of the roller causes the silicone suction cup fixedly connected to the roller to rotate. The silicone suction cup contacts the label base plate and is compressed, expelling air from the suction cup and thus adsorbing the label base plate. By adsorbing the silicone suction cup onto the label base plate and rolling it over the area where the label needs to be pasted, the label can be quickly pasted onto the item. This achieves the purpose of quickly pasting the label by rolling in reverse, improving the efficiency of label use.

[0026] 2. The present invention, through its scraper mechanism, allows the screw to be screwed into the threaded groove by turning the screw handle, compressing the spring spring and squeezing the scraper blade inward. This allows the blade at the bottom of the scraper to scrape the label paper adsorbed by the adsorption mechanism off the label paper base plate for adhesion. Simultaneously, turning the screw head rotates the bidirectional screw, allowing the two sliding limit baffles to move in opposite directions. This adjusts the limiting distance between the two sliding limit baffles and the label paper according to the size of the label paper, preventing the label paper from being applied crookedly.

[0027] 3. The present invention uses a limiting mechanism to screw the threaded rod into the lower body by rotating the screw rod. The lower end of the threaded rod presses the retaining ring downward, compressing the compression spring. The downward pressure of the two retaining rings can also press the wheel downward, thereby adjusting the tension of the label paper during the conveying process. This makes the label paper less prone to wrinkling during the conveying process and achieves better printing results. Attached Figure Description

[0030] The following will refer to the appendices in the embodiments of the present invention. Figure 1-10 The technical solutions in the embodiments of the present invention are clearly and completely described herein. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention. Please refer to Figure 3 , Figure 5 and Figure 6 This invention provides a reverse label support printer technical solution: a reverse label support printer includes a lower body 1, an upper body 2, an adsorption mechanism 3, a scraper mechanism 4, a paper roller 5, a limiting mechanism 6, a paper jam mechanism 7, a sensor 8, a print head 9, a conveying mechanism 10, a take-up roller 11, and a second motor 12. The upper body 2 and the lower body 1 are rotatably connected together. A paper outlet is provided at the front end where the lower body 1 and the upper body 2 meet. An adsorption mechanism 3 is movably provided at the paper outlet of the upper body 2.

[0031] The adsorption mechanism 3 includes a roller 301, axle 302, connecting post 303, silicone suction cup 304, fixing post 305, and pressure spring 306. The axle 302 is symmetrically fixedly connected to both ends of the roller 301. Multiple connecting posts 303 are fixedly distributed in a ring on the side of the roller 301. A silicone suction cup 304 is fixedly connected to each connecting post 303. The silicone suction cup 304 is made of styrene-butadiene rubber (SBR). The fixing post 305 is distributed in a ring below the silicone suction cup 304 and fixedly connected to the roller 301. One end of the pressure spring 306 is fixedly connected to the silicone suction cup 304, and the other end is fixedly connected to the fixing post 305.

[0032] It should be further explained that in actual use, the multiple silicone suction cups 304 provided on the roller 301 can adsorb the label paper base plate when the roller 301 rotates, so that it can rotate with the roller 301. Then, the scraper mechanism 4 scrapes the label paper off the label paper base plate, thereby realizing the scraping and pasting of the label by the rotation of the adsorption mechanism 3.

[0033] Please refer to Figure 4 , Figure 7 and Figure 8 A scraper mechanism 4 is provided at the paper outlet at the front end of the upper body 2. The scraper mechanism 4 includes a scraper 401, a limiting block 402, a screw 403, a screw handle 404, a spring 405, a limiting plate 406, a two-way lead screw 407, a sliding limiting baffle 408, and a screw head 409. The limiting block 402 is symmetrically arranged on the scraper 401. The screw 403 is threadedly connected to the center of the scraper 401. The screw handle 404 is fixedly connected to one end of the screw 403. The spring spring 405 is symmetrically fixedly connected to the inner side of the scraper 401.

[0034] The limiting plate 406 is symmetrically fixedly connected to the outside of the scraper 401. The scraper 401 has a sliding groove 4011 on its outside. The two ends of the bidirectional screw 407 are movably installed in the two limiting plates 406. The screw head 409 is fixedly connected to one end of the bidirectional screw 407. The two sliding limiting baffles 408 are threadedly connected to the bidirectional screw 407.

[0035] A slider is fixedly connected to the sliding limit baffle 408, and the sliding limit baffle 408 is movably connected to the slide groove 4011 through the slider.

[0036] It should be further explained that in actual use, the two sliding limit baffles 408 can limit the two sides of the scraped label sticker, so that it will not be crooked when pasted. At the same time, by observing the two sliding limit baffles 408, it can be seen whether it is pasted crookedly, which facilitates the pasting of the label.

[0037] Please refer to Figure 9The lower body 1 is equipped with a paper roller 5. A limiting mechanism 6 is provided in front of the paper roller 5. The limiting mechanism 6 includes a wheel 601, a retaining ring 602, a compression spring 603, a threaded rod 604, and a rotating rod 605. The upper end of the compression spring 603 is fixedly connected to the retaining ring 602, and the lower end of the compression spring 603 is fixedly connected to the lower body 1. The retaining ring 602 is equipped with a wheel 601. The upper part of the retaining ring 602 abuts against the threaded rod 604. The threaded rod 604 is threadedly connected to the lower body 1, and the rotating rod 605 is fixedly connected to the upper end of the threaded rod 604.

[0038] Further explanation is needed: In actual use, by simultaneously turning the rotary rod 605 to screw the threaded rod 604 into the lower body 1, the retaining ring 602 is pressed downward. The downward pressure of the two retaining rings 602 causes the wheel 601 to move downward, thereby adjusting the tension of the label paper and making it less prone to wrinkles during transportation.

[0039] Please refer to Figure 3 , Figure 9 Meanwhile, a paper jamming mechanism 7 is provided in front of the limiting mechanism 6, a sensor 8 is provided on the paper jamming mechanism 7, and a conveying mechanism 10 is provided in front of the paper jamming mechanism 7.

[0040] The conveying mechanism 10 includes a rolling wheel 101, a limiting end 102, a first gear 103, a second gear 104, and a first motor 105. The limiting end 102 is disposed on the lower body 1. The right end of the rolling wheel 101 is movably installed in the limiting end 102. The first gear 103 is fixedly connected to the left end of the rolling wheel 101. The second gear 104 is meshed with the first gear 103. The output shaft of the first motor 105 is fixedly connected to the second gear 104. The first motor 105 is fixedly installed inside the lower body 1.

[0041] Please refer to Figure 3 , Figure 4 The print head 9 is located at the center above the paper jam mechanism 7. The print head 9 is fixedly connected to the inside of the upper body 2. The take-up roller 11 is movably installed inside the upper body 2. The output end of the second motor 12 is fixedly connected to one end of the take-up roller 11. The second motor 12 is fixedly connected to one side of the upper body 2.

[0042] The front end of the upper body 2 is provided with a square groove 201, a mounting groove 202 and a threaded groove 203. The limiting block 402 is slidably disposed in the square groove 201, the screw 403 is threadedly connected in the threaded groove 203, and the elastic spring 405 is fixedly connected in the mounting groove 202.

[0043] The working principle of this invention is as follows: First, the upper body 2 is flipped upward, the paper roller 5 is taken out, the reverse label paper roll is placed on the paper roller 5, and then the label paper is pulled out and passed around the lower end of the limiting mechanism 6, then through the two limiting blocks on the paper clamping mechanism 7, through the upper part of the conveying mechanism 10, and then from the lower end of the adsorption mechanism 3 upward to fix the label paper base plate to the winding and fixing it on the take-up roller 11, thus completing the installation of the label paper; Then, by adjusting the position of the scraper 401 on the scraper mechanism 4, it can separate the label paper adsorbed by the adsorption mechanism 3 from the label paper base plate, scrape the label paper off the label paper base plate, and the label paper can be pasted by rotating the adsorption mechanism 3. At the same time, the sliding limit baffle 408 provided on the scraper mechanism 4 can limit the two sides of the scraped label paper, so that it is not easy to be pasted crookedly, thus achieving a better pasting effect.

[0044] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit the scope of protection of the present invention. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the essence and scope of the technical solutions of the present invention.
