[0028] This utility model embodiment provides a novel anti-drag printer, such as... Figure 1 , Figure 2 and Figure 3 As shown, the new anti-pull printer includes a printer body 10, and an anti-pull component 13 is provided between the printing component 11 and the paper output port 12 of the printer body 10; the printer body 10 is an existing thermal printer, and its printing and paper feeding principles are existing technologies, which will not be described in detail here.

[0029] During printing, the anti-pull component 13 collects the printing paper 20 between the printing component 11 and the paper output port 12; after printing is completed, the anti-pull component 13 then transmits the printing paper 20 out of the paper output port 12. In this embodiment, the anti-pull component 13 collects the printing paper 20 during the printing process (e.g., ...). Figure 3As shown, after printing is completed, the printing paper 20 is fed out from the paper output port 12, thereby avoiding the phenomenon of the printing paper 20 being pulled during the printing process and solving the problem of the printing paper 20 being pulled from the root.

[0030] The novel anti-pull printer provided in this embodiment of the utility model provides an anti-pull component 13 between the printing component 11 and the paper output port 12 of the printer body 10. The anti-pull component 13 first collects the printing paper 20 during the printing process, and then sends the printing paper 20 out from the paper output port 12 after printing is completed, thereby avoiding the phenomenon of the printing paper 20 being pulled during the printing process and solving the problem of the printing paper 20 being pulled from the root.

[0031] In specific implementation, such as Figure 1 , Figure 2 As shown, the anti-pull assembly 13 includes a rubber roller assembly 131, a drive device, a notch 132, and a storage space 133, wherein:

[0032] A rubber roller assembly 131 is located at the paper outlet 12; the rubber roller assembly 131 is connected to a drive device; the drive device is a motor or the like used to drive at least one rubber roller (as shown below) in the rubber roller assembly 131 to rotate;

[0033] The paper feeding channel between the rubber roller assembly 131 and the printing assembly 11 is provided with a notch 132; the length of the notch 132 perpendicular to the paper feeding direction must be greater than the width of the printing paper 20; the notch 132 connects to the storage space 133; the storage space 133 can accommodate the printing paper 20 that is arched from the notch 132.

[0034] During operation, the printing paper 20 is fed by the printer body 10 to the printing assembly 11 for printing. The front end of the printed paper 20 is then fed to the rubber roller assembly 131 and blocked. When the paper continues to be fed towards the rubber roller assembly 131, the printing paper 20 arches from the notch 132 towards the storage space 133 (e.g., ...). Figure 3 (As shown) until printing is complete; when printing is complete, the rubber roller group 131 is started, the rubber roller group 131 clamps the front end of the printing paper 20, and continues to move the printing paper 20 towards the paper outlet 12 until the printed paper 20 is sent out.

[0035] In this embodiment, the anti-pull component 13, consisting of a rubber roller group 131, a driving device, a notch 132, and a storage space 133, achieves the effect of storing the printing paper 20 during the printing process and outputting the printing paper 20 after printing is completed. The structure is simple and practical.

[0036] Preferably, the roller assembly 131 is equipped with a paper detection sensor. During printing, when the paper detection sensor detects that the front end of the paper 20 has entered or is close to the roller assembly 131, the roller assembly 131 starts to rotate, clamping the front end of the paper 20. The paper detection sensor includes, but is not limited to, existing thermistor sensors, reed switch sensors, photoelectric sensors, etc. Detecting the presence of paper using a paper detection sensor is a common technique in the printer industry; its structure and principle will not be elaborated further.

[0037] In specific implementation, such as Figure 2 As shown, the notch 132 is provided with an arc-shaped guide structure 1321. The arc-shaped structure can better guide the protective layer of the printing paper 20 into the storage space 133.

[0038] In specific implementation, such as Figure 3 As shown, a movable guide plate 134 is provided on the side of the notch 132 near the printing assembly 11; the movable guide plate 134 is provided with a connecting part 1341, which is movably connected to the side wall of the printer body 10 housing via the connecting part 1341. When the middle of the printing paper 20 is inserted into the storage space 133, the free end of the movable guide plate 134 is arched by the printing paper 20, which can increase the width of the notch 132 in the paper feeding direction, so that the middle of the printing paper 20 can enter the storage space 133 and exit more smoothly.

[0039] In specific implementation, such as Figure 2 As shown, a cutter assembly 14 is provided between the printing assembly 11 and the anti-pull assembly 13. The cutter assembly 14 is used for cutting roll paper or continuous printing paper. The cutter assembly 14 includes, but is not limited to, existing integrated cutters, separate cutters, etc., used for cutting printing paper.

[0040] In specific implementation, such as Figure 4 , Figure 5 As shown, the paper inlet 15 of the printer body 10 is provided with a paper width adjustment component. The paper width adjustment component includes a paper limiting piece 151. The paper limiting piece 151 extends outward from one end of the paper inlet 15 of the printer body 10 and bends downward along the side wall of the printer body 10 to form an extension 152. Through the structural design of the bent extension 152, it is convenient to extend the mounting structure of the paper limiting piece 151 to the outside of the printer body 10.

[0041] The printer body 10 has several paper width markings 101 on its side wall, which are transverse to the paper feeding direction; the paper width markings 101 are used to identify the type or width of different papers.

[0042] The extension 152 can be detachably connected to the side wall of the printer body 10 at different paper width markings 101; the detachable connection structure includes, but is not limited to, bolt connection structure, snap-fit ​​structure, etc.

[0043] During adjustment, the user only needs to remove and fix the paper limiter 151 on the side wall outside the printer body 10 without flipping or disassembling the printer body 10. The operation is convenient and the structure is simple. Furthermore, the structure in which the paper limiter 151 is detachably connected to the extension 152, the paper width indicator 101 and the side wall of the printer body 10 has a low manufacturing cost and can reduce the production cost of the printer.

[0044] This embodiment achieves the function of adjusting the position of the paper limiter according to different paper widths through a structure in which the paper limiter, extension, paper width indicator and printer body side wall are detachably connected. The structure is simple, the adjustment is convenient, and the production cost of the printer is reduced.

[0045] Furthermore, the extension 152 is provided with an indicator arrow 1524.

[0046] In specific implementation, such as Figure 4 , Figure 5 As shown, the extension 152 is provided with an indicator arrow 1524. When adjusting, the indicator arrow 1524 is aligned with the paper width mark 101 to improve the accuracy of the adjustment.

[0047] Furthermore, the paper width identifier 101 includes one or more of A4, A5, and A6.

[0048] In practice, the paper width marking 101 includes one or more of A4, A5, and A6. A4, A5, and A6 are commonly used paper types on the market. Through the paper width marking 101 of A4, A5, and A6, users can quickly locate the position of the limiting piece 141 according to their needs.

[0049] Furthermore, the paper width marking 101 is provided with a plurality of scales 102 adjacent to each other.

[0050] In practice, the paper limiters 151 on the printer are usually paired and symmetrically distributed in the paper feed path of the printer body 10; the paper width markings 101 that are matched with the paper limiters 151 are also paired and symmetrically set. When paper eccentricity adjustment is required, it is convenient to make precise eccentricity adjustment; or when adjusting the width of paper other than A4, A5, and A6 types, the paper width markings 101 can be used to make precise adjustment based on the difference between the actual paper width and the width of the similar A4, A5, or A6 paper by using several scales 102 set adjacent to each other.

[0051] Furthermore, the detachable connection structure between the extension 152 and the side wall of the printer body 10 includes: the side wall of the printer body 10 is provided with a plurality of first fixing grooves 103, and the extension 152 is provided with a first through hole 1521;

[0052] The first bolt passes through the first through hole 1521 and connects to the first fixing groove 103.

[0053] In specific implementation, such as Figure 4 , Figure 5 As shown, the detachable connection structure between the extension 152 and the side wall of the printer body 10 includes: the side wall of the printer body 10 is provided with a plurality of first fixing grooves 103, and the extension 152 is provided with a first through hole 1521.

[0054] The first bolt (not shown in the figure) passes through the first through hole 1521 and connects to the first fixing groove 103. The first fixing groove 103 is a blind groove or a through groove. When it is a blind groove, it has an internal thread for connecting with the first bolt. This embodiment features a detachable structure design that combines the first through hole 1521, the first fixing groove 103, and the first bolt, resulting in a simple structure and convenient use.

[0055] Furthermore, the cross-section of the first fixing groove 103 and / or the first through hole 1521 is elliptical.

[0056] In specific implementation, such as Figure 5 As shown, the cross-section of the first through hole 1521 is elliptical, and the length of the ellipse is set laterally to the paper feeding direction. The elliptical cross-section design of the first fixing groove 103 and / or the first through hole 1521 increases the lateral adjustment range.

[0057] Furthermore, the first fixing groove 103 is adjacent to the second fixing groove 104; the extension 152 is provided with a second through hole 1522; the first bolt passes through the second through hole 1522 and is connected to the second fixing groove 104.

[0058] In specific implementation, such as Figure 4 , Figure 5 As shown, the second fixing groove 104 has the same structure as the first fixing groove 103, and the second through hole 1522 has the same structure as the first through hole 1521. In this embodiment, by combining the added second fixing groove 104, second through hole 1522, and second bolt with the first fixing groove 103, first through hole 1521, and first bolt, the connection strength and connection stability of the paper sheet 151 are increased.

[0059] Furthermore, the extension 152 is provided with a protruding baffle 1523.

[0060] In specific implementation, such as Figure 5 As shown, the surface of the extension 152 is provided with a raised lever 1523. The structure of the raised lever 1523 makes it convenient for the user to move the paper limit sheet 151, thereby improving the width adjustment efficiency.
