Description

Technical Field

[0001] This utility model relates to the field of printer technology, and in particular to a label printer and a consumable component for the label printer. Background Technology

[0002] Label printers are essential printing equipment in many industries, including retail, manufacturing, logistics, apparel, and office. They are mainly used to output special labels with barcodes, text, or patterns.

[0003] These types of printing devices differ from ordinary office printers and are typically used in industrial environments such as factory assembly lines and warehouse management. Generally, label printers consist of two core components: the main unit and label consumables. To adapt to the needs of different scenarios, the same model of label printer often needs to be compatible with multiple sizes and types of label consumables (e.g., label paper). However, when changing label consumables, users need to manually confirm the specifications of the label consumables currently installed on the main unit before making the change. This increases the number of steps and thus affects the convenience of label printers.

[0004] The existing technical solution proposed by technicians is to set up an information reader in the device host and set up an information tag in the tag consumable. In this technical solution, after the tag consumable is installed in the device host, the information reader can read the information in the information tag for automatic detection and identification. However, during the information reading process, since the information tag is set to be movable relative to the reader, the communication signal between the information tag and the information reader is easily interfered with, which reduces the signal strength and thus affects the accuracy of information detection and identification. Utility Model Content

[0005] This utility model provides a consumable component that can solve at least one of the above-mentioned technical problems, and a label printer having the consumable component. The specific technical solution is as follows:

[0006] A consumable assembly, detachably mounted on the main body of a device equipped with an information reader, the consumable assembly comprising:

[0007] Printing media, used to carry text or images, and rotating about an axis of rotation; and

[0008] Information tags are used to store parameter information of the consumable components and can be read by the information reader;

[0009] The consumable assembly further includes a support assembly, which is fixedly installed to the device body and used to support the printing media; the information label is fixedly disposed on the support assembly; or,

[0010] The information tag rotates together with the printing medium around the rotation axis and has a first point and a second point that can be read / recognized by the information reader. In a first plane, the first point is connected to the rotation axis to form a first line, and the second point is connected to the rotation axis to form a second line. The included angle between the first line and the second line is in the range of 120° to 240°. The first plane is formed as a plane that cuts through the printing medium along a direction perpendicular to the rotation axis.

[0011] Furthermore, the printing medium is configured to be rotatable relative to the support assembly.

[0012] Furthermore, the support assembly includes a first baffle, a second baffle, and a fixed shaft. At least one of the first baffle and the second baffle is detachably connected to the fixed shaft. The information tag is fixed on one of the first baffle, the second baffle, and the fixed shaft. The support assembly is fixedly connected to the device body through the first baffle and the second baffle.

[0013] Furthermore, the fixed shaft is provided with at least one through hole, which is used to reduce communication signal interference between the information reader and the information tag.

[0014] Furthermore, the first baffle is provided with a second working part for positioning the first baffle to the main body of the device, and the second baffle is provided with a fourth working part for positioning the second baffle to the main body of the device. The structure of the second working part is different from that of the fourth working part.

[0015] Furthermore, the dimensions of the support component are variable along the axial direction of the printing medium.

[0016] Furthermore, the dimension of the fixed shaft along the axial direction of the printing medium is variable.

[0017] Furthermore, the fixed shaft includes a first end, a middle portion, and a second end connected sequentially along the axial direction of the printing medium, and at least one of the first end, the middle portion, and the second end is extendable and retractable along the axial direction of the printing medium.

[0018] Furthermore, the fixed shaft is formed by detachably connecting multiple shaft segments.

[0019] A second aspect of this utility model discloses a label printer, which includes the aforementioned consumable component and the device body, wherein the consumable component is detachably installed in the device body.

[0020] Compared with existing technologies, the label printer has an information reader in its main body and an information label storing information and a printing medium that can rotate around a rotation axis in its consumable component. The consumable component also includes a support component fixedly installed in the main body of the device. The information label is fixedly installed on the support component, or the information label rotates around the rotation axis together with the printing medium and has a first point and a second point that can be read / recognized by the information reader. In a first plane, the first point is connected to the rotation axis to form a first line, and the second point is connected to the rotation axis to form a second line. The included angle between the first line and the second line is in the range of 120° to 240°. The information reader is used to read the information in the information label. In this way, the communication signal between the information label and the information reader is not easily affected during the information reading process, and the accuracy of information detection and recognition is not easily affected, thereby further improving the stability of the communication signal transmission between the information reader and the information label.

[0035] like Figure 1 , Figure 2 and Figure 5 As shown, the consumable assembly 10 includes a printing medium 12, a roll 13, a first baffle 15, and a second baffle 16. The printing medium 12 is used to carry text or patterns. The printing medium 12 is mounted on the roll 13. The printing medium 12 and the roll 13 can rotate together around the rotation axis L. Along the radial direction of the roll 13, the roll 13 includes an outer wall 131 and an inner wall 132 that are spaced apart. The outer wall 131 of the roll 13 is used to support the printing medium 12. The first baffle 15 and the second baffle 16 are respectively used to connect to the two ends of the roll 13 in the axial direction.

[0036] In some embodiments, the printing medium 12 is configured as label paper, which includes a label and a backing paper. The label is placed on the backing paper and serves as a carrier for carrying text or patterns, etc.

[0037] In some implementations, the printing medium is set to thermal paper.

[0038] Figure 6 This is a perspective view of the first baffle in the consumable component involved in this utility model.

[0039] like Figure 1 , Figure 5 and Figure 6 As shown, the first baffle 15 is provided with a first baffle body 152 including a first positioning part 151 and a first mounting part. The first mounting part is configured as a through hole extending along the axial direction of the drum 13, or the first mounting part is configured as a groove with an opening facing away from the second baffle 16. The first positioning part 151 includes a first action part 1511 and a second action part 1512 connected to each other. The first action part 1511 is used to interact with the first mounting part, so that the first positioning part 151 is fixed to the first baffle body 152. The second action part 1512 is configured as a protrusion extending from the first action part 1511 toward a direction away from the second baffle 16. The second action part 1512 is used to interact with a first positioned part (not shown) provided in the equipment body, so that the first baffle 15 is positioned to the equipment body.

[0040] In some embodiments, the second actuating part 1512 is provided with a third receiving part 1512a, which is used to receive a protrusion provided in the first positioning part, or the third receiving part 1512a engages with the protrusion provided in the first positioning part, so that the first baffle 15 is more stably positioned to the device body.

[0041] Figure 7 This is a perspective view of the second baffle in the consumable component involved in this utility model.

[0042] like Figure 2 , Figure 5 and Figure 7 As shown, the second baffle 16 is provided with a second baffle body 162 including a second positioning part 161 and a second mounting part. The second mounting part is configured as a through hole extending along the axial direction of the drum 13, or the second mounting part is configured as a groove with an opening facing away from the first baffle 15. The second positioning part 161 includes a third action part 1611 and a fourth action part 1612 connected to each other. The third action part 1611 is used to interact with the second mounting part, so that the second positioning part 161 is fixed to the second baffle body 162. The fourth action part 1612 is configured as a protrusion extending from the third action part 1611 in a direction away from the first baffle 15. The fourth action part 1612 is used to interact with the second positioning part provided in the equipment body, so that the second baffle 16 is positioned to the equipment body.

[0043] In some embodiments, the first positioning portion is configured as a groove / through hole that matches the second actuating portion 1512, and the second positioning portion is configured as a groove / through hole that matches the fourth actuating portion 1612.

[0044] In some embodiments, the fourth actuating part 1612 is provided with a fourth receiving part 1612a, which is used to receive a protrusion provided in the second positioning part, or the fourth receiving part 1612a engages with the protrusion provided in the second positioning part, so that the second baffle 16 is more stably positioned to the device body.

[0045] In summary, through the interaction between the first positioning part 151 / second actuating part 1512 and the first positioned part, and through the interaction between the second positioning part 161 / fourth actuating part 1612 and the second positioned part, the consumable assembly 10 is installed onto the main body of the device.

[0046] In some embodiments, the first actuating part 1511 and the third actuating part 1611 have the same structure, and the first mounting part and the second mounting part have the same structure.

[0047] The construction of the second action part 1512 is different from that of the fourth action part 1612. For example, the shape of the second action part 1512 is different from that of the fourth action part 1612, or the size of the second action part 1512 is different from that of the fourth action part 1612, or the structure of the third receiving part 1512a in the second action part 1512 is different from that of the fourth receiving part 1612a in the fourth action part 1612. In this way, installation errors can be prevented when the consumable component 10 is installed into the main body of the device. That is to say, the second action part 1512 and the fourth action part 1612 can also be used for foolproofing. Correspondingly, the construction of the first positioning part and the second positioning part is also different. In this way, the second action part 1512, the first positioning part, the fourth action part 1612 and the second positioning part can be adapted to each other. In addition, it can simplify the operation and improve the user experience.

[0048] In some embodiments, the second action part 1512 and the fourth action part 1612 are configured as snap fasteners, and when the second action part 1512 and the fourth action part 1612 are disassembled, the fasteners are pressed to release the fixation.

[0049] like Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7As shown, the consumable assembly 10 is further provided with a fixed shaft 14. Along the axial direction of the drum 13, the fixed shaft 14 passes through the drum 13. The fixed shaft 14 includes a first end 141, a middle portion 142, and a second end 143 connected sequentially along the axial direction of the drum 13. Along the axial direction of the drum 13, the first end 141 is closer to the first baffle 15, and the second end 143 is closer to the second baffle 16. The first end 141 is provided with at least one third positioning part 1411, and the first baffle 15 is provided with at least one third positioned part 153. The third positioned part 153 and the first positioning part 151 are respectively located on both sides of the first baffle body 152. The third positioning part 1411 interacts with the third positioned part 153, so that the fixed shaft 14 is positioned and fixed to the first baffle 15. The second end 143 is provided with at least one fourth positioning part 1431, and the second baffle 16 is provided with... At least one fourth positioning part 163 is provided. The fourth positioning part 163 and the second positioning part 161 are respectively located on both sides of the second baffle body 162. The fourth positioning part 1431 is used to interact with the fourth positioning part 163 so that the fixed shaft 14 is positioned and fixed to the second baffle 16. The interaction between the third positioning part 1411 and the third positioning part 153 and the interaction between the fourth positioning part 1431 and the fourth positioning part 163 are all engaging, mutual squeezing or magnetic interaction. Through the interaction between the third positioning part 1411 and the third positioning part 153 and the fourth positioning part 1431 and the fourth positioning part 163, a fixed structure can be formed between the fixed shaft 14, the first baffle 15 and the second baffle 16. While the printing medium 12 is stably supported, the consumable component 10 can also be stably fixed in the device body.

[0050] In some implementations, such as Figure 6 and Figure 7 As shown, the first baffle 15 is also provided with a first receiving portion 154 for accommodating at least a portion of the first end 141, and the second baffle 16 is also provided with a second receiving portion 164 for accommodating at least a portion of the second end 143. Through the first receiving portion 154 and the second receiving portion 164, the fixed shaft 14 can be connected to the first baffle 15 and the second baffle 16 more stably.

[0051] In some embodiments, the first receiving portion 154 may be interchanged with the first end portion 141, and the second receiving portion 164 may be interchanged with the second end portion 143.

[0052] In some embodiments, the third positioning part 1411 and the fourth positioning part 1431 are configured as snap fasteners, and the third positioned part 153 and the fourth positioned part 163 are configured as grooves or through holes that engage with the snap fasteners. When the third positioned part 153 and the fourth positioned part 163 are configured as through holes, the third positioned part 153 communicates with the first receiving part 154, and the fourth positioned part 163 communicates with the second receiving part 164.

[0053] In some embodiments, the third positioning unit 1411 may be interchanged with the third positioned unit 153, and the fourth positioning unit 1431 may also be interchanged with the fourth positioned unit 163.

[0054] The roll 13, fixed shaft 14, first baffle 15 and second baffle 16 can together form a support assembly. The information label 11 is fixedly mounted on the support assembly. The support assembly is fixedly installed to the main body of the device. Therefore, the information label 11 is also fixedly mounted relative to the main body of the device. Specifically, the first baffle 15 and the second baffle 16 fix the support assembly to the main body of the device. The roll 13 is used to support the printing medium 12. The size of the support assembly can be changed along the axial direction of the roll 13, thereby enhancing the versatility of the consumable assembly 10.

[0055] Specifically, at least one of the first baffle 15 and the second baffle 16 is detachably connected to the drum 13 to facilitate maintenance and replacement, and the dimensions of the fixed shaft 14 in the axial direction of the drum 13 can also be adjusted to enable the consumable assembly / support assembly to have a wider range of adaptability.

[0056] Furthermore, at least one of the first baffle 15 and the second baffle 16 is detachably connected to the fixed shaft 14. With this configuration, fixed shafts 14 of different sizes can be pre-produced according to different needs, thereby producing consumable assemblies 10 of different sizes, which broadens the applicability of the first baffle 15 and the second baffle 16.

[0057] Furthermore, at least one of the first baffle 15 and the second baffle 16 is detachably connected to the fixed shaft 14, and the fixed shaft 14 is configured to have a variable dimension along the axial direction of the drum 13. For example, the fixed shaft 14 can extend and retract along the axial direction of the drum 13. Specifically, at least one of the first end 141, the middle portion 142, and the second end 143 can extend and retract along the axial direction of the drum 13. Preferably, the middle portion 142 can extend and retract along the axial direction of the drum 13. With such a configuration, the fixed shaft 14 / support assembly / consumable assembly can be universally used, while also avoiding the backlog of goods to reduce the production cost of the factory.

[0058] In some embodiments, the fixed shaft 14 may also be formed by detachably connecting multiple shaft segments, thereby enabling the fixed shaft 14 to have variable dimensions along the axial direction of the drum 13.

[0059] In some embodiments, the fixed shaft 14 may be detachably connected to only one of the first baffle 15 and the second baffle 16 to reduce the number of operation steps.

[0060] After the consumable component 10 is installed on the main body of the device, the second action part 1512 and the fourth action part 1612 can bring the information tag 11 as close as possible to the information reader 20, so that the information reader 20 can quickly and accurately read the information in the information tag 11. Specifically, during the installation process of the consumable component 10, through the interaction between the second action part 1512 and the fourth action part 1612 and the main body of the device, the consumable component 10 is fixedly installed on the main body of the device. At this time, the positions of the information tag 11 and the information reader 20 are relatively fixed, which can minimize the distance between the information tag 11 and the information reader 20.

[0061] In some embodiments, the information tag 11 is fixedly mounted on the fixed shaft 14; in some preferred embodiments, such as... Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the information tag 11 is disposed in the middle part 142 of the fixed shaft 14. The middle part 142 is also provided with at least one through hole 1421. The through hole 1421 can reduce the communication signal interference between the information reader 20 and the information tag 11, so that the signal transmission effect is better, thereby enabling the information reader 20 to read the information in the information tag 11 faster and more accurately. Specifically, the existence of the through hole will reduce the obstruction of signal transmission between the information tag 11 and the information reader 20, so that the communication effect between the information tag 11 and the information reader 20 is better. The obstruction can be a partition forming the middle part 142.

[0062] In some embodiments, the information tag 11 is fixedly disposed on the first baffle 15 or the second baffle 16, and correspondingly, the information reader 20 is disposed on the end of the device body corresponding to the first baffle 15 or the second baffle 16 on which the information tag 11 is disposed.

[0063] It is understandable that the shape of the support component / fixed shaft 14 should not be restricted, as long as the information label 11 is fixedly set on the support component / fixed shaft 14.

[0064] Figure 8 This is a perspective view of the information reader and another consumable component involved in this utility model; Figure 9 This is an exploded view of another consumable component involved in this utility model.

[0065] In some implementations, such as Figure 8 and Figure 9As shown, the label printer does not have a fixed shaft 14, a first baffle 15, or a second baffle 16. The information label 11 is fully affixed to the inner wall 132 of the roll 13. "Fully affixed" means that the information label 11 extends at least one complete circumference along the circumferential direction of the inner wall 132. After the consumable assembly 10 is installed on the main body of the device, the information reader 20 can immediately read the information of the information label 11 for identification, which helps to improve the printing speed of the label printer.

[0066] In some embodiments, at least one information tag 11 is disposed on the inner wall 132. The information tag 11 has a first point A and a second point B that can be read / identified by the information reader 20. By cutting the roll 13 / printing medium 12 along a direction perpendicular to the rotation axis L, a first plane M1 can be obtained. In the first plane M1, the first point A is connected to the rotation axis L to form a first line L1, and the second point B is connected to the rotation axis L to form a second line L2. The included angle α formed between the first line L1 and the second line L2 ranges from 120° to 240°. The first point A and the second point B can be two points on the same information tag 11 or points on different information tags 11.

[0067] Figure 10 , Figure 11 , Figure 12 and Figure 13 This is a plan view of the reel of the consumable assembly involved in this utility model, cut along a direction perpendicular to the axis of rotation of the reel. In some embodiments, such as Figure 10 As shown, only one information label 11 is provided on the inner wall 132 of the roll 13. The first point A and the second point B are located on the information label 11 respectively. At this time, the included angle α between the first line L1 and the second line L2 is 120° to 240°.

[0068] In some implementations, such as Figure 11 As shown, when two information tags 11 are provided on the inner wall 132 of the roll 13, the two information tags 11 are symmetrically arranged along the radial direction of the roll 13, and the first point A and the second point B are located on different information tags 11 respectively. At this time, the included angle α between the first connecting line L1 and the second connecting line L2 is 180°.

[0069] In some implementations, such as Figure 12As shown, when three information tags 11 are provided on the inner wall 132 of the roll 13, the three information tags 11 are evenly spaced along the circumferential direction of the roll 13, and the first point A and the second point B are located on different information tags 11. At this time, the included angle α between the first connecting line L1 and the second connecting line L2 is 120°. When the three information tags 11 are not evenly spaced, the first point A and the second point B will always exist in two of the three information tags, and the included angle α between the first connecting line L1 and the second connecting line L2 is between 120° and 240°.

[0070] In some implementations, such as Figure 13 As shown, when four information tags 11 are provided on the inner wall 132 of the roll 13, the four information tags 11 are evenly spaced along the circumferential direction of the roll 13, or in other words, the four information tags 11 are symmetrically arranged in pairs along the radial direction of the roll 13. The first point A and the second point B will always exist on two of the information tags 11. At this time, the included angle α between the first connecting line L1 and the second connecting line L2 is 180°.

[0071] In some embodiments, the number of information tags 11 provided on the inner wall 132 of the roll 13 may be greater than four, but the first point A and the second point B will always exist on two of the information tags 11, and the included angle α between the first line L1 and the second line L2 is between 120° and 240°.

[0072] Figure 14 This is a schematic diagram of the consumable component of this utility model, after being cut along a direction perpendicular to the rotation axis of the roll, projected onto a second plane.

[0073] In some implementations, such as Figure 14 As shown, only one information tag 11 is provided on the inner wall 132 of the roll 13. The first point A and the second point B are respectively located on the information tag 11. The information tag 11 and the information reader 20 are both projected onto a second plane M2 that is perpendicular to the thickness direction of the information reader 20. In the second plane M2, the midpoint P of the line connecting the projection point A1 of the first point A and the projection point B1 of the second point B moves relative to the projection of the information reader 20 in the second plane M2, and the straight line of the trajectory of the midpoint P is perpendicular to the rotation axis L.

[0074] In some embodiments, multiple information tags 11 may be provided on the inner wall 132 of the roll 13. The first point A and the second point B are located at two of the multiple information tags 11 respectively. The midpoint P of the line connecting the projection point A1 of the first point A on the second plane M2 and the projection point B1 of the second point B on the second plane M2 moves relative to the projection of the information reader 20 on the second plane M2, and the straight line of the movement trajectory of the midpoint P is perpendicular to the rotation axis L.

[0075] As described above, the information tag 11 can be fixedly set on the support component, the first point A and the second point B still exist on the information tag 11, and the midpoint P of the line connecting the projection point A1 of the first point A in the second plane M2 and the projection point B1 of the second point B in the second plane M2 is stationary relative to the projection of the reader 20 in the second plane M2.

[0076] The main body of the device includes a driving component and a rubber roller driven to rotate by the driving component. During the operation of the label printer, the printing medium 12 is set to be rotatable relative to the support component. Furthermore, the roll 13 and the printing medium 12 rotate relative to the fixed shaft 14 / information label 11, while the fixed shaft 14 remains stationary. Specifically, the driving component drives the rubber roller to rotate, the rubber roller drives the printing medium 12 to move, and the printing medium 12 then drives the roll 13 to rotate. However, the relative positions of the information label 11 and the information reader 20 do not change, which can further improve the stability of the communication signal transmission between the reader 20 and the information label 11.

[0077] [Beneficial Effects]

[0078] Compared with the prior art, the consumable component 10 and the label printer having the consumable component 10 provided by this utility model have the following beneficial effects:

[0079] Firstly, the label printer's main body is equipped with an information reader 20, and the consumable component 10 is equipped with an information tag 11 that stores information. The information tag 11 is fixedly mounted on the support component / fixed shaft 14. The information reader 20 is used to read the information in the information tag 11. During the operation of the label printer, the roll 13 and the printing medium 12 rotate relative to the fixed shaft 14 / information tag 11, while the fixed shaft 14 remains stationary. With this configuration, the relative positions of the information reader 20 and the information tag 11 do not change during the information reading process, and the communication signal between the information tag 11 and the information reader 20 is not easily interfered with or affected, thus the accuracy of information detection and recognition is not easily affected.

[0080] Secondly, the fixed shaft 14 is provided with at least one through hole 1421 to reduce communication signal interference between the information reader 20 and the information tag 11. Therefore, during the information reading process, the communication signal between the information tag 11 and the information reader 20 is less affected, and the signal strength is less affected, thus reducing the impact on the accuracy of information detection and recognition.

[0081] Thirdly, at least one of the first baffle 15 and the second baffle 16 is detachably connected to the fixed shaft 14. In this way, during the production process of the fixed shaft 14, fixed shafts 14 of different sizes can be pre-produced according to different needs, thereby producing consumable components of different sizes, which broadens the applicability of the first baffle 15 and the second baffle 16.

[0082] Fourthly, at least one of the first baffle 15 and the second baffle 16 is detachably connected to the fixed shaft 14, and the fixed shaft 14 is configured to have a variable dimension along the axial direction of the drum 13. This configuration enables the fixed shaft 14 / support assembly / consumable assembly 10 to be universal, while also avoiding inventory buildup and reducing factory production costs. Compared with the third aspect, the support assembly / consumable assembly 10 with this configuration has a wider range of applications.

[0083] Fifthly, the fixed shaft 14 can be detachably connected to only one of the first baffle 15 and the second baffle 16, which can reduce the user's operation steps.

[0084] Sixthly, the construction of the second function 1512 is different from that of the fourth function 1612, in order to prevent fooling and also to make the information reader 20 and the information tag 11 in the closest possible position.

[0085] Seventhly, the information tag 11 has a first point A and a second point B that can be read / identified by the information reader 20. In the first plane M1, the first point A is connected to the rotation axis L to form a first line L1, and the second point B is connected to the rotation axis L to form a second line L2. The included angle α between the first line L1 and the second line L2 ranges from 120° to 240°. With this configuration, during the information reading process, the communication signal between the information tag 11 and the information reader 20 is less affected by interference, or even not affected at all, thereby enabling the information reader 20 to accurately detect and identify the information in the information tag 11.

[0086] Eighthly, when the information tag 11 is set on the inner wall 132, in the second plane M2, the midpoint P of the line connecting the projection point A1 of the first point A and the projection point B1 of the second point B moves relative to the projection of the information reader 20 in the second plane M2, and the straight line of the trajectory of the midpoint P is perpendicular to the rotation axis L. Alternatively, when the information tag 11 is fixedly set on the support component, the midpoint P of the line connecting the projection point A1 of the first point A and the projection point B1 of the second point B in the second plane M2 remains stationary relative to the projection of the reader 20 in the second plane M2. With this setting, the communication signal between the information tag 11 and the information reader 20 is not easily affected during the information reading process, and the accuracy of information detection and recognition is not easily affected.
