Technical Field

[0001] The utility model relates to the technical field of printers, in particular to a paper limiting block and a printer. Background Art

[0002] With the development of society, printers are becoming increasingly widely used. For example, a label printer, also known as a courier label printer or logistics label printer, is a device specifically designed to quickly and efficiently print express labels. The widespread use of label printers has greatly improved the speed and accuracy of package processing.

[0003] For printers, ensuring that face-sheet labels are correctly aligned and conveyed in the correct direction is a fundamental requirement. This requirement is typically achieved through paper stoppers. The paper stoppers serve as guides for face-sheet labels. However, during use, it has been found that some face-sheet labels with pre-tear lines and notched edges can easily arch as they pass through the paper stoppers. This can cause the notched edges of the face-sheet labels to interfere with the end of the paper stoppers, leading to paper jams, face-sheet label breaks, and other printing problems.

[0004] Therefore, how to solve the problem in the related art that the face sheet printer is not suitable for printing on face sheet label paper with a pre-tear line and a notch on the edge has become an important technical problem to be solved by those skilled in the art. Utility Model Content

DETAILED DESCRIPTION

[0036] To make the purpose, technical solutions, and advantages of the present invention more clear, the following will be combined with the accompanying drawings to clearly and completely describe the technical solutions of the present invention. Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0037] The following combination Figures 1 to 7 The utility model is described as a paper limiting block.

[0038] like Figures 1 to 7 As shown, the paper limiting block provided by the embodiment of the present invention includes a limiting block body and a smoothing portion 3.

[0039] Specifically, the limit block body comprises a support portion 1 and a limit portion. The limit portion is located on one side of the support portion 1, and a conveying channel 2 for the consumables 10 to pass through is formed between the limit portion and the support portion 1. The support portion 1 serves as the bottom wall of the conveying channel 2, supporting the consumables 10 within the conveying channel 2. The limit portion is used to prevent the consumables 10 from moving away from the support portion 1 and to ensure that the consumables 10 move in the correct conveying direction.

[0040] The smoothing portion 3 is disposed at the inlet end of the conveying channel 2. The smoothing portion 3 and the limiting portion are located on the same side of the supporting portion 1 and are fixedly connected to the limiting portion. The smoothing portion 3 is configured to exert a force on the consumable 10 in a direction away from the limiting portion when in contact with the consumable 10, thereby preventing the consumable 10 from bulging toward the limiting portion. In particular, consumables 10 having a pre-tear line 17 are prone to bulging at the pre-tear line 17 before entering the conveying channel 2, forming sharp edges. The smoothing portion 3 on the paper limiting block in this embodiment can prevent bulging and the formation of sharp edges.

[0041] With such arrangement, when the consumable 10 enters the conveying channel 2, the limit block body can limit the consumable 10 in the conveying channel 2 so that the consumable 10 moves in the correct conveying direction; before the consumable 10 enters the conveying channel 2, the smoothing portion 3 prevents the consumable 10 from bulging and deforming toward the limit block body, especially the consumable 10 with a pre-tear line 17 and a notch 11 on the edge. By preventing the consumable 10 from bulging and deforming toward the limit block body, the notch 11 on the edge of the consumable 10 can be effectively prevented from interfering with the limit block body, effectively avoiding the problem of consumables being stuck or being pulled apart. Installing the paper limit block provided in the embodiment of the utility model on a face sheet printer can solve the problem that the face sheet printer is not suitable for printing on face sheet label paper with a pre-tear line 17 and a notch 11 on the edge.

[0042] It should be noted that the above-mentioned consumables 10 may be, but are not limited to, single-sided label paper, etc., and the edge of the consumables 10 may have a notch 11 or may not have a notch 11. For consumables 10 with a notch 11 on the edge, the paper limit block provided in the embodiment of the present invention can well avoid problems such as jamming and breaking caused by interference between the notch 11 and the limit block body; for consumables 10 without a notch 11 on the edge, the paper limit block provided in the embodiment of the present invention can also ensure the normal transportation of such consumables 10, and there will be no problems of jamming and breaking. The paper limit block provided in the embodiment of the present invention has strong adaptability and can be used to limit the transportation of different types of consumables 10, thereby expanding the scope of application of the printer with the paper limit block provided in this embodiment for consumables 10.

[0043] In an embodiment of the present invention, the paper limit block also includes a connecting portion 4, which is arranged between the smoothing portion 3 and the limiting portion. Moreover, the connecting portion 4 extends from the limiting portion in a direction away from the outlet end of the conveying channel 2 to increase the distance between the smoothing portion 3 and the limiting portion, thereby increasing the difficulty of interference between the notch 11 on the edge of the consumable 10 and the limit block body, thereby further avoiding the problems of jamming and breaking.

[0044] Specifically, the connecting portion 4 includes a connecting plate, which is parallel to the supporting portion 1 , one end of the connecting plate is fixedly connected to the limiting portion, and the other end of the connecting plate is fixedly connected to the smoothing portion 3 .

[0045] In this embodiment, the smoothing portion 3 , the connecting portion 4 and the limiting portion are connected to form an integrated structure, thereby increasing the stability of the smoothing portion 3 .

[0046] Specifically, the smoothing portion 3, connecting portion 4, and the stopper body can be separately processed and then fixedly connected together by bonding, welding, or the like. Alternatively, the smoothing portion 3, connecting portion 4, and the stopper body can be integrally formed using an injection molding process. The processing method for the paper stopper is not specifically limited herein.

[0047] In the embodiment of the present invention, the surface of the smoothing portion 3 facing the supporting portion 1 is a cylindrical surface, the axis of the cylindrical surface is parallel to the supporting portion 1, and the axis of the cylindrical surface is perpendicular to the conveying direction of the conveying channel 2. The conveying direction of the conveying channel 2 is parallel to the supporting portion 1, referring to Figure 5 The direction indicated by m.

[0048] The cross section of the cylindrical surface is perpendicular to the axis of the cylindrical surface, and the cross section of the cylindrical surface is arc-shaped, so that the surface of the smoothing part 3 facing the supporting part 1 is smooth, avoiding damage to the consumables 10 by the smoothing part 3, and is conducive to improving the smoothing effect of the consumables 10.

[0049] Specifically, the cross-sectional shape of the cylindrical surface can be a semicircular arc. Accordingly, the surface of the smoothing portion 3 facing the supporting portion 1 is a semi-cylindrical surface, which is convenient for processing.

[0050] In this embodiment, a process groove 5 is provided on the side of the smoothing portion 3 away from the supporting portion 1. The process groove 5 can appropriately reduce the wall thickness of the smoothing portion 3. During the injection molding process, shrinkage defects caused by the large wall thickness can be avoided, thereby ensuring the surface quality and structural strength of the smoothing portion 3.

[0051] In the embodiment of the present invention, the limiting portion includes a first limiting portion 6 and a second limiting portion 7 .

[0052] The first limiter 6 is provided on one side of the supporting portion 1 close to the smoothing portion 3 , with a distance between the first limiter 6 and the supporting portion 1 , so that the consumable 10 passes between the first limiter 6 and the supporting portion 1 . The first limiter 6 is used to limit the consumable 10 from moving away from the supporting portion 1 .

[0053] The second limiting portion 7 is provided between the first limiting portion 6 and the supporting portion 1, and the second limiting portion 7 corresponds to the edge of the consumable 10 and is used to limit the position of the edge of the consumable 10 along the reference direction. The reference direction is parallel to the supporting portion 1 and perpendicular to the conveying direction of the conveying channel 2. Figure 5 The direction indicated by n.

[0054] When the consumables 10 moves along the conveying channel 2, the second limiting portion 7 interacts with the edge of the consumables 10 to limit the consumables 10 from deviating from the conveying direction, so that the consumables 10 move in the correct conveying direction, avoiding the problem of skewed consumable output.

[0055] In the embodiment of the present invention, the distance between the first limiting portion 6 and the supporting portion 1 gradually decreases from the inlet end to the outlet end of the conveying channel 2. In other words, the cross-sectional size of the inlet end of the conveying channel 2 is relatively large, which facilitates the smooth entry of the consumables 10 into the conveying channel 2.

[0056] Moreover, the consumables 10 are generally wound on a reel 12, the axis of which is parallel to the supporting portion 1 and perpendicular to the conveying direction. The rotation of the reel 12 can release the consumables 10 or reel the consumables 10. The paper limit block is located on the side of the reel 12 close to the consumables outlet of the printer body 16. The location of the paper limit block and the reel 12 ensures that the consumables 10 have a certain inclination angle before entering the conveying channel 2. The consumables 10 are not parallel to the supporting portion 1. The first limit portion 6 is arranged in a structure with a gradually changing distance from the supporting portion 1, which can gradually reduce the inclination angle of the consumables 10, avoid damage to the consumables 10, and make the conveying of the consumables 10 smoother.

[0057] In a specific embodiment, the first limiting portion 6 can be configured as follows: Figure 5 and Figure 6 The surface shown.

[0058] The limit block body also includes a reinforcing rib 13, which is arranged on the side of the first limit portion 6 away from the supporting portion 1. The reinforcing rib 13 is perpendicular to the supporting portion 1 and the first limit portion 6 and is fixedly connected to the first limit portion 6. The provision of the reinforcing rib 13 can increase the structural strength of the limit block body.

[0059] In the embodiment of the present invention, the paper limiting block further includes an inlet guide structure and / or a return guide structure.

[0060] The import guide structure is arranged at one end of at least one of the supporting part 1 and the second limiting part 7 close to the smoothing part 3. The import guide structure is used to guide the process of the consumables 10 entering the conveying channel 2, so that the consumables 10 can enter the conveying channel 2 more smoothly.

[0061] Specifically, the inlet guide structure includes a first guide slope 8, referring to Figure 5 and Figure 6 , to increase the cross-sectional size of the inlet end of the conveying channel 2.

[0062] The first guiding slope 8 may be provided only on the supporting portion 1 , or only on the second limiting portion 7 , or both.

[0063] The retraction guide structure is arranged at an end of at least one of the first limiting portion 6 and the second limiting portion 7 away from the smoothing portion 3. The retraction guide structure is used to guide the consumable 10 during the process of retracting the consumable so that the consumable 10 can be smoothly retracted to the conveying channel 2.

[0064] Specifically, the retraction guide structure includes a second guide slope 9 and a guide curved surface 18. Figure 5 and Figure 6 The second guide inclined surface 9 is provided on the second limiting portion 7 , and the guide curved surface 18 is provided on the first limiting portion 6 .

[0065] The guide curved surface 18 may be provided only on the first limiting portion 6 ; the second guide inclined surface 9 may be provided only on the second limiting portion 7 ; or the guide curved surface 18 may be provided on the first limiting portion 6 and the second guide inclined surface 9 may be provided on the second limiting portion 7 at the same time.

[0066] In the embodiment of the present invention, a connecting assembly is provided on the limit block body, and the connecting assembly is used to connect with the printer body 16 to achieve installation and fixation of the paper limit block on the printer body 16 .

[0067] The connection assembly includes a positioning block 14 and a connecting block 15. The positioning block 14 is fixed to the paper limit block body, and the connecting block 15 is connected to the positioning block 14. The printer body 16 is provided with a positioning slot that mates with the positioning block 14 to position the paper limit block on the printer body 16. The connecting block 15 is located at the bottom of the positioning slot. The connecting block 15 has a connecting hole, and the printer body 16 has a threaded hole. The connecting block 15 and the printer body 16 are fixed together using screws, thereby installing the paper limit block on the printer body 16.

[0068] On the other hand, an embodiment of the present invention further provides a printer, including a printer body 16 and a paper limit block, wherein a pair of paper limit blocks are provided, and the pair of paper limit blocks are distributed along the reference direction and respectively interact with the side edges of the consumable material 10.

[0069] At least one of the pair of paper stoppers is the paper stopper provided in any of the aforementioned embodiments. The paper stopper provided in the aforementioned embodiments effectively prevents interference with the consumable 10 having the pre-tear line 17 and the notch 11. Therefore, the printer in this embodiment can prevent the consumable 10 from getting stuck or being torn, and offers the advantages of smooth entry and exit of the consumable 10 and excellent printing results. The derivation process for the beneficial effects of the printer in this embodiment of the utility model is generally similar to that for the aforementioned paper stopper, and will not be further elaborated here.

[0070] In the embodiment of the present invention, the type of printer is not limited, for example, the printer can be a single-sided printer, etc. In other words, as long as the printer can use the paper limit block in the embodiment of the present invention, it will be fine.

[0071] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein.
