A portable cloud printer

Abstract

This utility model discloses a portable cloud printer, including a cloud printer body. The cloud printer body has an internal paper tray and an external paper tray at its top. An anti-shrinkage paper component is installed inside the paper tray. By incorporating the anti-shrinkage paper component, after the cloud printer body dispenses a ticket, the first and second electromagnetic coils are de-energized. At this time, a first spring pushes a pressing plate, which applies pressure to the printing paper, effectively preventing the paper from shrinking due to residual vibrations from internal components or slight external contact after dispensing. This ensures the paper extends stably from the external paper tray, avoiding paper wrinkles, paper jams, or missing print content. This significantly improves the stability and reliability of the printing process, allowing users to obtain complete printed documents without frequent paper adjustments.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. By setting up an anti-shrinkage paper component, after the cloud printer dispenses the ticket, the first and second electromagnetic coils are de-energized. At this time, the first spring pushes the pressing plate, which applies a pressing and limiting effect to the printing paper. This effectively prevents the printing paper from shrinking due to residual vibration of internal components or slight external contact after the paper is dispensed. It ensures that the printing paper can stably extend from the paper tray, avoiding paper wrinkles, paper jams, or partial missing printing content. This significantly improves the stability and reliability of the printing process, allowing users to obtain complete printed documents without frequently adjusting the paper position.

[0016] 2. By setting up a paper cutting component, the sliding block can slide on the guide rod. When the user needs to cut the printing paper, he only needs to push the push plate to drive the paper cutter to move along the sliding groove. With the cooperation of the second spring, the paper cutter can quickly and neatly cut the printing paper, avoiding the problem of uneven paper edges or damage to the printed content caused by manually tearing paper, further improving the convenience of use and the aesthetics of the printed document.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figure 1 , Figure 2 , Figure 3 and Figure 5 This utility model provides a technical solution: a portable cloud printer, including a cloud printer body 1, a paper slot 2 inside the cloud printer body 1, a paper output slot 3 on the top of the cloud printer body 1, an anti-shrinkage paper component inside the paper slot 2, a replacement cover 6 movably connected to the top of the cloud printer body 1, and a protective component on one side of the cloud printer body 1.

[0025] The anti-shrinkage paper assembly includes a limiting plate 41, which is fixedly installed on the inner wall of the paper tray 2. First springs 42 are symmetrically fixedly installed inside the limiting plate 41. A pressing plate 43 is fixedly installed on one side of each of the two first springs 42. A first electromagnetic coil 44 is fixedly installed on the inner side of the pressing plate 43. A second electromagnetic coil 45 is fixedly installed on the inner wall of the limiting plate 41. This structure can limit the paper's movement, preventing it from shrinking back due to external influences, thus making the paper output from the cloud printer body 1 more stable. The protective assembly includes a rotating shaft 71, which is rotatably connected to one side of the cloud printer body 1. A torsion spring 72 is fitted onto the outer end of the rotating shaft 71. A protective plate 73 is fixedly installed at one end of the rotating shaft 71. The pressing plate 43 is slidably connected to the inner wall of the limiting plate 41. The first electromagnetic coil 44 and the second electromagnetic coil 45 have opposite magnetic poles and attract each other. The protective plate 73 is movably connected to the charging port of the cloud printer body 1. The torsion spring 72 is located between the inner wall of the cloud printer body 1 and the protective plate 73. Through the action of the rotating shaft 71 and the torsion spring 72, the protective plate 73 is always covered at the charging port, which can effectively prevent dust, water stains and other impurities from entering the charging port, protect the charging interface from damage, extend the service life of the cloud printer, and when charging is needed, the protective plate 73 can be gently opened, which is simple and convenient to operate.

[0026] Please see Figure 1 , Figure 2 and Figure 4 The paper output tray 3 is equipped with a paper cutting component, which includes guide rods 51. Two guide rods 51 are symmetrically fixedly installed on the inner wall of the paper output tray 3, and sliding blocks 52 are slidably connected to the outer ends of the two guide rods 51. A second spring 53 is sleeved on the outer end of the guide rods 51. A paper cutter 54 is fixedly installed between the two sliding blocks 52. A push plate 55 is fixedly installed on the top of the paper cutter 54. A sliding groove 56 is opened on the top of the cloud printer body 1. The guide rods 51 are located in the groove of the inner wall of the paper output tray 3. The second spring 53 is located between the inner wall of the paper output tray 3 and the sliding block 52. The push plate 55 passes through the interior of the sliding groove 56 and extends to the top of the cloud printer body 1. The structure is simple and compact, and no additional complex driving device is required. The paper cutting operation can be completed by simply pushing it manually. This reduces the manufacturing cost of the equipment and the probability of failure. It allows users to easily handle the cutting of printed paper in outdoor or mobile office scenarios, effectively improving the overall practicality of the portable cloud printer.

[0027] Working principle: The operator opens the replacement cover 6 and places the printing roll paper into the paper tray 2. One end of the printing roll paper passes through the limiting plate 41 and extends from the paper output tray 3 to the top of the cloud printer body 1. When printing is required, the first electromagnetic coil 44 and the second electromagnetic coil 45 are energized. With the help of the attraction between the first electromagnetic coil 44 and the second electromagnetic coil 45, the pressing plate 43 is adjusted into the limiting plate 41. At this time, the pressure applied to one end of the printing roll paper disappears, and the cloud printer body 1 begins to print and output the printing roll paper.

[0028] After printing is completed, the power supply to the first electromagnetic coil 44 and the second electromagnetic coil 45 is cut off. The first spring 42 pushes the pressing plate 43 to limit and fix one end of the printed paper roll. The push plate 55 is pulled, and the push plate 55 drives the sliding block 52 to slide at the outer end of the guide rod 51. The sliding block 52 pushes the paper cutter 54, and the paper cutter 54 cuts the printed ticket.

[0029] When the device does not need to be charged, the rotating shaft 71 rebounds due to the elasticity of the torsion spring 72, and the rotating shaft 71 drives the protective plate 73 to rebound, which protects the charging port. The above is the working process of the entire device. All contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0030] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
