Therefore, they should not be construed as limitations on the present application. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, features defined with "first" and "second" may explicitly or implicitly include one or more of the stated features. In the description of this application, "a plurality of" means two or more, unless otherwise explicitly specified.

[0034] The following detailed description of some embodiments of this application is provided in conjunction with the accompanying drawings. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0035] like Figures 1 to 9 As shown, according to a first aspect of this application, this application provides an adjustable paper feeding mechanism for use in a printer. The adjustable paper feeding mechanism includes a fixing component 300, a paper blocking component 100, and a supply component 200 for holding a paper roll. The fixing component 300 is connected to the printer frame. One end of the supply component 200 is connected to the fixing component 300. The paper blocking component 100 is rotatably mounted on the other end of the supply component 200 to restrict the paper roll within the supply component 200, thereby enabling the adjustable paper feeding mechanism to feed paper to the printer.

[0036] In an optional embodiment, the paper stop assembly 100 includes a paper stop 10 and a toggle member 20. The paper stop 10 has a movable cavity 111. The toggle member 20 has a first end and a second end, with a first suction member 22 on the first end and the second end. The supply assembly 200 has a second suction member 202. The movable cavity 111 has a third suction member 13 at the end away from the second suction member 202. The toggle member 20 is slidably installed in the movable cavity 111, so that the first suction member 22 can cooperate with the second suction member 202 to restrict the paper stop 10 in a first state, so that the paper roll can be restricted by the paper stop 10 in the supply assembly 200. The first suction member 22 can cooperate with the third suction member 13 to release the restriction of the paper stop 10, so that the paper stop 10 can rotate to a second state to release the restriction on the paper roll. The paper stop 10 can be restricted in the first state or the restriction on the paper stop 10 can be released without the aid of tools, which facilitates the quick replacement of the paper roll and solves the problem of cumbersome paper roll replacement in existing printers.

[0037] For example, the paper stop 10 can cut in a first state and a second state. When the paper stop 10 is in the first state, the paper stop 10 is perpendicular to the axis of the supply assembly 200 or the paper roll to form a physical barrier, thereby preventing the paper roll from falling off the supply assembly 200. When the paper stop 10 is in the second state, the paper stop 10 rotates to be parallel to the axis of the supply assembly 200 or the paper roll, thereby allowing the paper roll to be taken out or put in from the axis of the supply assembly 200. When the paper stopper 10 is in the first state, the first adsorption member 22 and the second adsorption member 202 at the first end adsorb each other, so that the paper stopper 10 can be vertically fixed on the supply component 200. When the paper stopper 10 is in the second state, the first adsorption member 22 and the third adsorption member 13 at the second end adsorb each other to release the constraint on the paper stopper 10, so that the paper stopper 10 can rotate freely relative to the supply component 200, thereby rotating from the first state to the second state, or from the second state to the first state, realizing the rapid loading and unloading and stable restriction of the paper roll on the supply component 200.

[0038] It should be noted that when the first suction member 22 and the second suction member 202 at the first end are attracted to each other, the actuating member 20 is located at the bottom of the paper stop 10, which can lower the center of gravity of the paper stop 10 to prevent the paper stop 10 from rotating freely relative to the supply component 200. The weight of the paper stop component 100 enhances the stability in the locked state, ensuring a secure lock. When the first suction member 22 and the third suction member 13 at the second end are attracted to each other, the center of gravity of the paper stop 10 moves to the top, allowing the paper stop 10 to rotate towards the second state side under the gravity of the actuating member 20. This facilitates one-handed operation and makes it easier to replace the paper roll from the supply component 200. The attraction force between the first suction member 22 and the second suction member 202 needs to be manually switched by actively actuating the actuating member 20 to avoid accidental release due to vibration during printing.

[0039] In an optional embodiment, the paper stop 10 includes a paper stop rod 11 and a paper stop end cap 12. A movable cavity 111 is formed in the paper stop rod 11. One end of the paper stop rod 11 is provided with a rotating part 112, which is used to rotatably connect with the supply assembly 200. A third suction member 13 is disposed on the paper stop end cap 12, which is installed at the other end of the paper stop rod 11 and is used to movably install the actuating member 20 in the movable cavity 111.

[0040] In an optional embodiment, the supply assembly 200 is provided with a slide groove 2012, which is arranged along the length direction of the supply assembly 200. The rotating part 112 is rotatably installed in the slide groove 2012 and can slide along the length direction of the slide groove 2012 so as to accommodate paper rolls of different widths and limit the position of the paper rolls to prevent the paper rolls from shaking axially.

[0041] In an optional embodiment, the supply assembly 200 includes a supply shaft 201 and a shaft end cap 203. A groove 2012 is formed in the supply shaft 201 and extends along the length of the supply shaft 201. The shaft end cap 203 covers the end of the supply shaft 201 away from the fixing assembly 300 and is used to confine the paper stop bar 11 in the groove 2012. The length of the groove 2012 is equal to the difference between the maximum width and the minimum width of the paper roll, plus a certain buffer allowance, typically 15 mm.

[0042] In an optional embodiment, a strip groove is formed in the supply shaft 201, and a slide groove 2012 is formed on both sides of the strip groove. The paper stop assembly 100 is slidably installed in the strip groove, the rotating part 112 cooperates with the slide groove 2012, and the second suction member 202 is disposed at the bottom of the strip groove to ensure the stability of the paper stop assembly 100 in the strip groove.

[0043] In an optional embodiment, one of the axial end cap 203 of the supply assembly 200 and the paper stop assembly 100 is provided with a limiting protrusion 2031, and the other of the axial end cap 203 of the supply assembly 200 and the paper stop assembly 100 is provided with a limiting groove 113. The limiting protrusion 2031 cooperates with the limiting groove 113 to restrict the paper stop assembly 100 in the second state and prevent accidental closure due to vibration or accidental contact.

[0044] For example, a limiting protrusion 2031 is formed on the shaft end cap 203, and a limiting groove 113 is formed on the paper stop assembly 100. When the paper stop assembly 100 rotates, the limiting groove 113 slides along the outer side wall of the shaft end cap 203 until it engages with the limiting protrusion 2031, thereby generating tactile feedback and accompanied by a clicking sound to indicate that the paper stop assembly 100 has rotated into place.

[0045] In an optional embodiment, the actuating member 20 includes a carrier member 21, a sliding block 211 of the carrier member 21, and a driving part 212 connected to the sliding block 211. The sliding block 211 is slidably installed in the movable cavity 111, and the driving part 212 is disposed on the outside of the paper stop member 10 for driving the sliding block 211 to move along the height direction of the movable cavity 111, so as to realize the switching of the paper stop assembly 100 between the first state and the second state.

[0046] In an optional embodiment, the first adsorption member 22 includes a first magnet 221 and a second magnet 222. The first and second ends of the sliding block 211 are each provided with a groove structure 2111, and the first magnet 221 and the second magnet 222 are mounted opposite each other in the groove structure 2111. The groove structure 2111 includes a first groove and a second groove, and the first magnet 221 and the second magnet 222 are mounted opposite each other in the first groove and the second groove.

[0047] In an optional embodiment, the N pole of the first magnet 221 faces outward and the S pole of the second magnet 222 faces outward to form an axial magnetic circuit, thereby increasing the adsorption force of the first adsorption member 22 by 20% to 30%.

[0048] In one optional embodiment, the second adsorption member 202 includes a magnetic metal sheet, and the supply shaft 201 of the supply assembly 200 has a first mounting groove 2011 formed along its length, in which the magnetic metal sheet is accommodated. The first mounting groove 2011 may be formed at the bottom of a strip groove, or it may be a strip groove; this application does not impose any limitation on this.

[0049] In an optional embodiment, the third adsorption member 13 includes a magnetic metal block, and the axial end cap 203 of the supply assembly 200 is provided with a second mounting groove 121, in which the magnetic metal block is fixed.

[0050] In an optional embodiment, the paper stop assembly 100 is provided with a first friction plate 14, and the fixing assembly 300 is provided with a second friction plate 301. The first friction plate 14 and the second friction plate 301 are arranged opposite to each other and are used to contact the end face of the paper roll to eliminate axial gaps and absorb vibration energy.
