[0044] In order to make the purpose, technical scheme and advantages of the present application more clear, the present application is further described in detail below in combination with the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and do not limit the present application.

[0045] In the prior art, in a label printer, the label paper is clamped between the printing head and the printing roller, and the movement of the label paper is driven by the rotation of the printing roller, cooperating with the printing head to realize the printing function. However, there is a situation that the label paper is not clamped tightly, thereby affecting the printing effect.

[0046] That is, since the printing head is elastic, if there is a large bending amplitude of the label paper, when the label paper passes through the printing head, it will push the elastic head to move away from the label paper, so there is a situation that the label paper is not clamped tightly, thereby affecting the printing effect

[0047] Therefore, in order to solve the above technical problems, please refer to Figures 1-3 The present application provides a printer, which comprises a main body 10.

[0048] The main machine 110 provides stable support for all other components, ensuring the stability and durability of the printer during operation. In addition, the main machine 110 is the core component of the entire label printer, responsible for controlling the printing process, processing print data, and providing support and power for other components. The main machine 110 integrates circuit boards, power management modules, data processing units, and other key electronic components. When receiving a print instruction, the heating print head causes the ink or carbon powder on the ribbon to transfer to the paper or other medium, completing the printing task.

[0049] The main body 10 forms a paper bin 10a inside for placing label paper, and a paper path 10b communicating with the paper bin 10a. The paper path 10b has a paper inlet end and a paper outlet end. The paper inlet end guides the unprinted label paper in the paper bin 10a into the paper path 10b, and the paper path 10b restricts the direction of the paper to ensure the accuracy of the label paper printing. The paper outlet end guides the printed label paper to travel to the outside of the main body 10 according to the preset path.

[0050] The main body 10 is provided with an elastic print head 101 and a circumferential wall enclosing the paper bin 10a. The paper bin 10a and the elastic print head 101 are arranged along the first direction XX. The circumferential wall includes a paper feeding plate 102 arranged near the elastic print head 101. The elastic print head 101 is located between the paper path 10b and the paper feeding plate 102. The label paper in the paper bin 10a passes through the paper feeding plate 102, the elastic print head 101, and the paper path 10b in turn, and finally extends to the outer surface of the main body 10, which can be torn by the user according to the demand.

[0051] The elastic print head 101 can include a print head, a bracket, and a spring. The bracket connects the print head and the spring, and the spring is connected to the main body 10. The spring can be deformed under pressure, so the elastic print head 101 has a certain elasticity, which can adapt to label papers of different thicknesses and maintain constant contact force between the print head and the paper, ensuring the printing effect.

[0052] In the embodiment of the present application, please refer to Figure 3 The side of the paper feeding plate 102 facing the paper bin 10a has a paper feeding surface 1021, and the side of the print head facing the paper bin 10a has a printing surface 1011. The included angle between the paper feeding surface 1021 and the printing surface 1011 is A, which satisfies: 120°≤A≤160°. A can be 120°, 130°, 140°, 150°, 160°, or any range between any two of the above.

[0053] When the label paper is conveyed from the paper feeding surface 1021 to the printing surface 1011, a proper bending needs to be formed to generate a friction force, which pushes the elastic printing head 101 to generate a reaction force, so as to realize clamping. If the angle is too small (for example, 90°), the bending is too sharp, which can cause the printing head to be "pushed open", and the contact pressure is reduced. The bending of the angle A between the paper feeding surface 1021 and the printing surface 1011 is in the range of 120° to 160°, which makes the normal pressure of the label paper on the elastic printing head 101 more uniform, and the elastic printing head 101 can dynamically adjust the contact surface (that is, the printing surface 1011), so as to ensure the printing clarity.

[0054] It also needs to be understood that the label paper generally includes a base paper and a surface paper, the surface paper is used to carry the printed information, and needs to form a good bonding force with the adhesive, and the base paper is a release paper, and the surface paper is bonded to the base paper.

[0055] The paper bin 10a and the elastic printing head 101 are arranged along the first direction XX, and the paper in the paper bin 10a is printed through the elastic printing head 101 after passing through the paper feeding plate 102. Therefore, by setting the angle A between the paper feeding surface 1021 and the printing surface 1011 in the range of 120° to 160°, the possibility of separation of the base paper and the surface paper due to the too large bending angle of the label paper at the connection between the paper bin 10a and the paper feeding plate 102 can be reduced, and the printing stability can be ensured.

[0056] It needs to be understood that the printer is a thermal transfer printer, so in the embodiments of the present application, referring to 4-6, the printing surface 1011 is provided with a heating printing line 1012, wherein the heating printing line 1012 is composed of hundreds of thousands of micro-resistance heating elements, which are usually arranged in a row at high density to cover the printing width. The heating elements are usually made of ceramic substrate or special alloy, which can ensure rapid heating, cooling and long-term durability.

[0057] The heating printing line 1012 is uniformly distributed along the length direction of the elastic printing head 101, which can ensure the uniformity of the temperature field in the horizontal (for example, bar code) or vertical (for example, label) printing, and avoid local blur or breakpoint.

[0058] Optionally, the paper feeding channel 10b has two side wall surfaces 10b1 which are spaced apart along the first direction XX, and the heating printing line 1012 is located between the two side wall surfaces 10b1 and is spaced apart from the two side wall surfaces 10b1. In this way, the label paper is not pressed or is less pressed by the side wall surfaces 10b1 during movement, so as to reduce the friction, and further ensure the smoothness of the label paper in the paper feeding channel 10b.

[0059] Further, along the first direction XX, the distance between the two side wall surfaces 10b1 is W, W satisfies: 1.5mm≤W≤4mm, W can be 1.5mm, 2mm, 3mm, 4mm and any range between any two of the above, by W being in the above range, when the label paper is relatively thick, the label paper is also difficult to be pressed by the side wall surface 10b1, thereby ensuring the smoothness of the label paper in the paper passage 10b.

[0060] The first direction XX can be the width direction of the printer, or the length direction of the printer, and the embodiments of the present application do not make any limitation, and the first direction XX is exemplarily taken as the length direction of the printer.

[0061] In addition, by limiting the distance between the two side wall surfaces 10b1 along the first direction XX, that is, limiting the size of the opening of the paper passage 10b, the possibility of dust and other impurities contacting the print head through the paper passage 10b can be reduced, the printing effect is ensured, and the size of the opening of the paper passage 10b is appropriate, thereby facilitating the miniaturization design of the printer.

[0062] In an embodiment of the present application, along the first direction XX, the distance between one of the two side wall surfaces 10b1 and the heating printing line 1012 is W1, W1 satisfies: 0mm<W1≤3mm, and the distance between the other of the two side wall surfaces 10b1 and the heating printing line 1012 is W2, W2 satisfies: 0mm<W2≤3mm, wherein W1 can be 0.5mm, 1mm, 2mm, 3mm and any value between any two of the above, and W2 can be 0.5mm, 1mm, 2mm, 3mm and any value between any two of the above, by the appropriate size of W1 and W2, when the label paper is relatively thick, the label paper is also difficult to be pressed by the side wall surface 10b1, thereby ensuring the smoothness of the label paper in the paper passage 10b.

[0063] Optionally, the two side wall surfaces 10b1 are respectively a first side wall surface and a second side wall surface, and the printer further comprises a paper cutter 20, the paper cutter 20 is arranged on the main body 10 and located at the end of the paper passage 10b away from the elastic print head 101, and the paper cutter 20 is connected to the first side wall surface, by the paper cutter 20, the continuity of the label paper can be cut off, thereby facilitating the paper from the bottom paper.

[0064] And the heating printing line 1012 is located between the paper cutter 20 and the second side wall surface, that is, after the label paper is printed, the label paper reaches the paper cutter 20 through the paper passage 10b, that is, the label paper can be prevented from being blocked by the paper cutter 20 or the second side wall surface to affect the normal paper output of the label paper, thereby ensuring the smoothness of the label paper.

[0065] In addition, the paper tearing cutter 20 is arranged at an angle with the side wall 10b1 on which the paper tearing cutter 20 is arranged, so that the label paper can be conveniently arranged at an angle with the paper tearing cutter 20, and the paper tearing cutter 20 can press against the label paper, thereby facilitating the tearing of the label paper. In addition, the paper tearing cutter 20 will not excessively occupy the vertical space when the size of the paper tearing cutter 20 is certain, thereby reducing the risk of the paper tearing cutter 20 protruding from the main body 10 and hurting people. Similarly, the paper tearing cutter 20 will not excessively occupy the space of the paper passing channel 10b, thereby ensuring the smoothness of the label paper passing.

[0066] In an embodiment, the paper passing channel 10b has two side walls 10b1 arranged at intervals, and the paper tearing cutter 20 is arranged on one of the two side walls 10b1, and the paper tearing cutter 20 is arranged at an angle with the side wall 10b1 on which the paper tearing cutter 20 is arranged.

[0067] In an embodiment, the paper passing channel 10b has two side walls 10b1 arranged at intervals, and the paper tearing cutter 20 is arranged on one of the two side walls 10b1, and the paper tearing cutter 20 is arranged at an angle with the side wall 10b1 on which the paper tearing cutter 20 is arranged.

[0068] It can be understood that when the main body 10 includes the main machine 110 and the cover 120, one of the two side walls 10b1 is formed by the main machine 110, and the other side wall 10b1 is formed by the cover 120.

[0069] Further, the angle between the paper tearing cutter 20 and the side wall 10b1 on which the paper tearing cutter 20 is arranged is α, and α satisfies 5°≤α≤60°, wherein α can be 5°, 10°, 20°, 30°, 40°, 50°, 60° or a range between any two of the above values.

[0070] By being in the above range, the label paper can be conveniently arranged at an angle with the paper tearing cutter 20, the paper tearing cutter 20 can press against the label paper, thereby facilitating the tearing of the label paper. In addition, the paper tearing cutter 20 can have a certain spacing with the side wall 10b1 on which the paper tearing cutter 20 is arranged, and the label paper can fully contact the paper tearing cutter 20, thereby ensuring the smoothness of the tearing.

[0071] In addition, by being in the above range, when the size of the paper tearing cutter 20 is certain, the paper tearing cutter 20 will not excessively occupy the vertical space, thereby reducing the risk of the paper tearing cutter 20 protruding from the main body 10 and hurting people. Similarly, the paper tearing cutter 20 will not excessively occupy the space of the paper passing channel 10b, thereby ensuring the smoothness of the label paper passing.

[0072] In an embodiment, please refer to Figures 1-2The main body 10 comprises a main machine 110 and a cover 120, the cover 120 is rotationally connected to the main machine 110, the cover 120 and the main machine 110 define a paper bin 10a, the printer further comprises a paper tearing cutter 20, the paper tearing cutter 20 is located at one end of the paper conveying channel 10b far away from the elastic printing head 101.

[0073] The cover 120 has a covering position and an uncovering position during rotation, when the cover 120 is at the covering position, the paper bin 10a can be protected from dust from the outside, and the paper conveying channel 10b can be formed between the main machine 110 and the cover 120, thereby limiting the paper conveying direction of the label paper.

[0074] When the cover 120 is at the uncovering position, the paper bin 10a can be exposed, which is convenient for the user to replace the label paper, and also facilitates the inspection of the printing head, sensor and other structures on the main machine 110.

[0075] As described above, the paper tearing cutter 20 can be arranged on the main machine 110 or the cover 120, when the paper tearing cutter 20 is arranged on the main machine 110, the main machine 110 does not need to be opened and closed like the cover 120, and when tearing paper, the cover 120 will not be subjected to the opening force in the opening direction, and the cover 120 is not easy to be permanently displaced relative to the main machine 110 due to long-term paper tearing, which causes the cover 120 to be difficult to cooperate with the main machine 110 to clamp the label paper when being closed, thereby affecting the printing effect.

[0076] When the paper tearing cutter 20 is arranged on the cover 120, the paper tearing cutter 20 is directly exposed after the cover 120 is opened, which is convenient for the replacement and maintenance of the paper tearing cutter 20, and in the embodiment of the application, the paper tearing cutter 20 is preferably arranged on the cover 120.

[0077] Further, referring to Figures 4-6 The paper tearing cutter 20 is located in the paper conveying channel 10b, since the main body 10 forms the paper conveying channel 10b, when the paper tearing part is located inside the paper conveying channel 10b, i.e. the paper tearing part is located inside the main body 10, the paper tearing part will not protrude from the outer surface of the main body 10, so that the user is difficult to be cut by the protruding paper tearing part when contacting the printer, thereby ensuring the safety of the entire printer.

[0078] In an embodiment of the application, the paper conveying surface 1021 is provided with a plurality of first paper guide ribs 1022, the first paper guide ribs 1022 are arranged in the inclined direction of the paper conveying plate 102, and the plurality of first paper guide ribs 1022 are arranged in the second direction YY, and the second direction YY is perpendicular to the first direction XX.

[0079] The first paper guide strip 1022 can reduce the contact area between the label paper and the paper feeding surface 1021, thereby reducing the friction and improving the paper feeding smoothness. The first paper guide strip 1022 is arranged along the inclined direction of the paper feeding plate 102, and can guide the label paper to further ensure the paper feeding smoothness.

[0080] When the first direction XX is the length direction of the printer, the second direction YY can be the width direction of the printer, and the second direction YY should also be the width direction of the label paper.

[0081] Further, along the second direction YY, the width of the first paper guide strip 1022 is W3, and W3 satisfies 0.1mm≤W3≤1mm, where W3 can be 0.1mm, 0.3mm, 0.7mm, 1mm, and any value between any two of the above.

[0082] By setting W3 in the above range, that is, the width of the first paper guide strip 1022 is appropriate, the label paper can be prevented from being cut by the first paper guide strip 1022, and the friction between the first paper guide strip 1022 and the label paper is appropriate, thereby ensuring the paper feeding smoothness of the label paper.

[0083] In an embodiment, referring to Figure 7 , the printer further comprises a sliding assembly 40 and two spaced apart paper blocking plates 30, the two paper blocking plates 30 form part of the peripheral wall of the paper bin 10a, and the paper feeding plate 102 is provided with a avoiding slot 102a for the sliding assembly 40 to move.

[0084] That is, by moving the paper blocking plate 30, the size of the paper bin 10a can be adjusted, on the one hand, the label paper is convenient to take and place, and on the other hand, the label paper of different widths can be adapted.

[0085] It should be understood that in order to ensure the stability of the movement of the paper blocking plate 30, a guide rail or the like sliding assembly 40 is arranged on the main body 10, and the sliding assembly 40 is connected with the paper blocking plate 30, thereby ensuring the stability of the movement of the paper blocking plate 30. In order to reduce the space occupied by the sliding assembly 40 in the paper bin 10a and affect the paper feeding of the label paper, the sliding assembly 40 is located outside the paper bin 10a. Therefore, by arranging the avoiding slot 102a, the sliding assembly 40 can extend into the paper bin 10a to be connected with the paper blocking plate 30, which not only makes the printer compact, but also ensures the paper feeding smoothness of the label paper.

[0086] Referring to Figure 6 , in an embodiment of the present application, the wall surface of the paper feeding channel 10b is provided with a plurality of second paper guide strips 10b2, the second paper guide strips 10b2 are arranged along the paper feeding direction of the paper feeding channel 10b, and the plurality of second paper guide strips 10b2 are arranged in the second direction YY, and the second direction YY is perpendicular to the first direction XX.

[0087] The paper running channel 10b includes two oppositely arranged walls, that is, the second paper guide rib 10b2 can be arranged on one of the walls, or both walls are provided with the second paper guide rib 10b2, which is not limited here and is arranged according to the actual situation.

[0088] Through the arrangement of the second paper guide rib 10b2, the contact area between the label paper and the wall of the paper running channel 10b can be reduced, thereby reducing the friction and improving the smoothness of the paper running. The second paper guide rib 10b2 is arranged along the paper running direction of the paper running channel 10b, which can also guide the paper running of the label paper, thereby further ensuring the smoothness of the label paper running.

[0089] When the first direction XX is the length direction of the printer, the second direction YY can be the width of the printer, and the second direction YY should also be the width direction of the label paper.

[0090] Further, along the second direction YY, the width of the first paper guide rib 1022 is W4, and W3 satisfies: 0.1mm≤W4≤0.6mm, wherein W3 can be 0.1mm, 0.2mm, 0.4mm, 0.6mm and any value between any two of the above.

[0091] By W4 being in the above range, that is, the width of the second paper guide rib 10b2 is appropriate, the label paper can be prevented from being cut by the second paper guide rib 10b2, and at the same time, the friction between the second paper guide rib 10b2 and the label paper can be appropriate, thereby ensuring the smoothness of the label paper running.

[0092] The same or similar reference numerals in the drawings of the embodiments correspond to the same or similar components; in the description of the present application, it should be understood that if the terms "upper", "lower", "left", "right" and the like indicate the orientation or positional relationship shown in the drawings, they are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the devices or elements referred to must have a particular orientation, be constructed and operated in a particular orientation, therefore the terms describing the positional relationship in the drawings are only used for exemplary illustration, and cannot be understood as a limitation of the present patent, any modification, equivalent replacement and improvement made within the spirit and principle of the present application should be included in the protection scope of the present application.
