[0002] At present, all walks of life often need to use various types of labels in production and operation, for example, labels on market goods, transaction receipts and the like, and the labels are generally small and are usually printed by printers using, for example, thermal transfer printing technology. Usually, the printing parameters of such thermal printers are fixed and cannot be changed, for example, printing speed and temperature, according to different paper rolls, and for paper rolls that do not meet the printing parameters, the best printing effect cannot be achieved, and the paper rolls can be damaged, causing unnecessary waste.

[0003] The thermal printer in the prior art usually uses radio frequency identification technology to obtain the relevant information of the paper roll and to prevent counterfeiting, and the technical mechanism is usually to set the RFID on the label reel or label paper and to identify it by the antenna set on the printer housing without contact. This way requires strict paper roll manufacturing, resulting in high production cost.

[0004] In addition, the printer often has a paper jam caused by the scattering of consumable paper during use. In view of this situation, the printer in the prior art protects the consumable by setting a single independent support shaft and a surrounding edge structure on the support shaft. The support shaft is assembled on the printer to support the consumable, and the surrounding edge structure limits the consumable on the support shaft to prevent the scattering of the consumable paper. However, this structure brings great difficulty to the user in replacing the consumable, and the operation of replacing the consumable is complex, time-consuming and laborious, which affects the user's experience.

[0049] Many specific details are set forth in the following description in conjunction with embodiments in order to provide a full understanding of the present invention. However, it should be understood that the following embodiments and detailed description are for illustrative purposes only and do not limit the scope of protection of the present invention.

[0050] like Figures 1-4 As shown, this utility model provides a consumable carrier component 20. When placed in a printer, the consumable carrier component 20 can conduct the printer circuit (referring to the detection circuit used by the printer for consumable detection) or change the capacitance in the printer circuit. The consumable carrier component 20 is provided with a conductive part 30, which is an integral structure with the consumable carrier component 20, or the conductive part 30 and the consumable carrier component 20 are a detachable structure; or, when the consumable carrier component 20 is placed in the printer, the capacitance in the printer circuit changes.

[0051] Specifically, this solution uses two types of consumable carrier components 20: one is a conductive consumable carrier component 20 used to conduct the printer circuit; the other is a conductive or insulating consumable carrier component 20. The printer's receiving portion 11 can be configured as a capacitor, so that the capacitance of the receiving portion 11 changes when the consumable carrier component 20 is placed in it. These two methods facilitate the differentiation of different printing consumables and can reduce manufacturing costs compared to using RFID technology for identification.

[0052] The consumable support component 20 and the conductive part 30 can be detachably connected. The conductive part 30 can be a support frame with a metal sheet, or it can be a metal sheet fixed to the consumable support component 20 by bolts. There is no specific limitation here. This facilitates the maintenance and replacement of the component during use. Alternatively, the conductive part 30 can be a metal sheet, which can be fixed to the consumable support component 20 by common techniques such as welding.

[0053] For example, the consumable support member 20 includes a fixed shaft, with conductive portions 30 provided at both ends or one end of the fixed shaft; or the fixed shaft is made of a conductive material to form conductive portions. The fixed shaft may be partially or entirely made of a conductive material.

[0054] Specifically, the consumable carrying component 20 can also be a fixed shaft for winding consumables, with conductive parts 30 at both ends; or the entire fixed shaft can be made of conductive material; or a conductor strip can pass through the through hole of the consumable paper and then be connected to the receiving part; no specific limitation is made here.

[0055] like Figures 1-2 As shown, the printer of this utility model embodiment includes a printer body 10 and a consumable assembly detachably installed in the printer body 10, wherein the consumable assembly includes consumables and a consumable carrier member 20 for mounting consumables (e.g., paper rolls).

[0056] The printer body 10 has a receiving part 11, and the consumable carrier component 20 can be assembled into the receiving part 11 and can be removed from the receiving part 11. The printer body 10 includes a body 12 and an outer cover 13. The outer cover 13 is disposed on the body 12 and can open or close the receiving part 11. The outer cover 13 is opened during the insertion or removal of the consumable carrier component 20 and closed when the consumable carrier component 20 is placed in place, so as to limit and protect the consumable carrier component 20.

[0057] It should be noted that consumables may include thermal paper, ribbons, carbon ribbons, etc.; the consumable support component 20 can hold any of the consumables mentioned above; the printer may be a thermal printer, a dot matrix printer, or a thermal transfer printer.

[0058] Specifically, the outer cover 13, for example... Figure 11 The flip cover shown is connected to the body 12; in an optional embodiment, the outer cover 13 can also be connected to the body 12 in a detachable manner, that is, the outer cover 13 can be directly removed from the body 12. This is not limited here and will not be elaborated further.

[0059] like Figures 3-4 As shown, in some embodiments, the consumable carrying component 20 includes a cylindrical body 21 and two end caps 22. One of the two end caps 22 is a fixed end cap 22a and the other is a detachable end cap 22b. The fixed end cap 22a is assembled with the cylindrical body 21 or formed as a single unit. The detachable end cap 22b is connected to the cylindrical body 21, for example, by means of snap-fit ​​or magnetic attraction. In an optional embodiment, both end caps 22 can be detachable end caps.

[0060] The tube body 21 has an installation port 211, through which consumables can be inserted into the tube body 21 and radially limited by the tube body 21 to prevent the consumables from moving. A detachable end cap 22b is disposed on the tube body 21 corresponding to the installation port 211. Preferably, when the detachable end cap 22b is installed on the tube body 21, it can at least partially block the installation port 211 to prevent the consumables from detaching from the tube body 21. More preferably, the detachable end cap 22b can completely cover the installation port 211 to complete the lateral limitation of the consumables.

[0061] The cartridge body 21 is provided with an outlet section 212, and the print head is provided on the machine body 12. Consumables can be supplied to the print head through the outlet section 212 for printing. The specific structure and operation of the print head can be referred to existing technology, and will not be elaborated here; please continue to refer to [the relevant literature]. Figure 4 In this embodiment, the outlet 212 is preferably connected to the mounting port 211 to facilitate the installation of consumables and the pulling out of paper.

[0062] In other alternative embodiments, the conductive part 30 can be directly disposed at any position on the consumable support member 20, including the side of the consumable support member 20 or the cylinder body 21; or the conductive part 30 can be directly disposed on the consumable, by removing the two end caps 22 of the consumable support member 20, placing the consumable in the consumable support member 20, and the conductive part 30 is disposed on the exposed portion of the consumable relative to the consumable support member 20.

[0063] Furthermore, the consumable support component 20 may also include a support shaft 23 that mates with a through hole on the consumable (e.g., consumable roll). The support shaft 23 may be fixed or assembled with one of the end caps 22. When the consumable is inserted into the tube body 21 through the mounting port 211, the through hole on the consumable and the support shaft 23 form a hole-shaft engagement to limit the position of the consumable in the tube body 21 and fix the axis of rotation of the consumable, which is beneficial for positioning the consumable and promoting stable paper output.

[0064] In other alternative embodiments, the consumable support member 20 may retain only the support shaft 23 and at least one end cap 22, while the cylinder body 21 may be omitted. The conductive part 30 may be provided on the end cap 22 or on the consumable.

[0065] In this embodiment of the invention, the printer is equipped with a detection device for detecting relevant information of consumables installed in the printer, such as at least one of production information, type parameter information, usage information, and anti-counterfeiting information. The consumable assembly includes a component to be detected. When the consumable assembly is installed in the printer, the component to be detected can be detected by the detection device to determine at least one of the consumable's production information, type parameter information, usage information, and anti-counterfeiting information. The component to be detected may be configured as a conductive element, which can be installed on at least one of the consumable carrier component or the consumable itself, or integrally formed with the consumable carrier component, or set independently of the consumable carrier component and the consumable.

[0066] In this embodiment of the utility model, the consumable support component 20 serves as the component to be tested, and the consumable support component 20 is provided with a conductive part 30. The printer body 10 is provided with a detection device, which includes a control part and an electrical contact part.

[0067] When the consumable carrier component 20 is installed into the receiving part 11, the conductive part 30 can form a contact engagement with the electrical contact part 40. The printer body 10 is equipped with a control unit, such as the printer's main control board or processor. When the electrical contact part 40 contacts the conductive part 30, the printer's circuitry is activated. The control unit then uses the received electrical signal to identify and determine at least one of the following: consumable carrier component 20's production information, type parameter information, usage information, and anti-counterfeiting information.

[0068] See Figure 16 Specifically, when the consumable carrier component 20 is placed in the receiving part 11, the consumable carrier component 20 acts as a conductor, and different consumable carrier components 20 can be set with different resistance values. At this time, a processor with an ADC module can be used, which is connected to the consumable carrier component 20 through the main control board. After the circuit is turned on, the ADC module can obtain the voltage value of the current consumable carrier component 20, and then compare it with the voltage information of each consumable carrier component pre-stored in the processor to determine the model or parameters of the current consumable carrier component. Alternatively, the processor can calculate the current value in the circuit, that is, obtain the voltage value across the consumable carrier component 20 through the ADC module, and then calculate the current current value based on the resistance value in the circuit. Different current values ​​correspond to different consumable carrier components 20, so identification can be performed.

[0069] In an optional embodiment, the electrical signal can also be a data-transmitting electrical signal. For example, the conductive part 30 is a readable and writable chip. When the consumable carrier member 20 is installed in the receiving part 11, the chip and the electrical contact part 40 form a contact engagement to identify and acquire information in the chip, and the information can be written into the chip when needed.

[0070] In this embodiment, the conductive part 30 can be disposed at any position on the consumable support member 20 as needed. Specifically, the conductive part 30 is preferably disposed on the outside of the consumable support member 20 so as to form a contact engagement with the electrical contact part 40 when the consumable support member 20 is installed into the receiving part 11, thereby improving the connection stability between the conductive part 30 and the electrical contact part 40 and improving the printing quality. The specific placement position of the conductive part 30 will be described in detail below.

[0071] The body 12 has two side walls 121 corresponding to the two end caps 22. The two side walls 121 are respectively a first side wall 121a corresponding to the detachable end cap 22b and a second side wall 121b corresponding to the fixed end cap 22a. In some embodiments of this utility model, the conductive part 30 may be provided on the end cap 22; such as Figures 3-5 As shown, the conductive part 30 is specifically disposed on the outer middle of the detachable end cover 22b, and the electrical contact part 40 is disposed on the first sidewall 121a. In another optional embodiment, the conductive part 30 may also be disposed on the outer middle of the fixed end cover 22a, and correspondingly, the electrical contact part 40 may be disposed on the second sidewall 121b, as shown. Figure 6 As shown; in another alternative embodiment, the electrical contact 40 can also be set independently, that is, the electrical contact 40 can be detachable from the printer body 10.

[0072] In the above embodiments, the conductive part 30 and the electrical contact part 40 are preferably in direct contact. For example, when the consumable support member 20 is installed in the receiving part 11, the conductive part 30 and the electrical contact part 40 are flush in the height direction and in direct contact. In other embodiments, when the consumable support member 20 is installed in the receiving part 11, the conductive part 30 and the electrical contact part 40 may also be offset in the height direction and cannot be in direct contact. In this case, for example, an electrical connection between the conductive part 30 and the electrical contact part is achieved through a conductive connection part. For example, the fixed end cap 22a is a conductive end cap, and the electrical contact part 40 is electrically connected to the conductive part 30 through the conductive fixed end cap 22a. In another optional embodiment, the conductive part 30 may also be provided by the conductive fixed end cap 22a itself.

[0073] As an extension of the above embodiment, both end caps 22 may also be provided with conductive portions 30, preferably the two conductive portions 30 are mutually conductive and respectively form contact with two electrical contact portions 40 on the first sidewall 121a and the second sidewall 121b; for example, the consumable carrier member 20 is a conductive paper tube as a whole, and the two conductive portions 30 are electrically connected through the conductive consumable carrier member 20; in another optional embodiment, the conductive portion 30 may also be provided by the conductive consumable carrier member 20 itself.

[0074] In an optional embodiment, such as Figures 7-8 As shown, the support shaft 23 is preferably configured to penetrate the cylinder body 21; wherein, the support shaft 23 is an integral conductive support shaft, and the two conductive parts 30 are electrically connected through the support shaft 23, or the support shaft 23 itself provides the conductive parts 30. Optionally, both end caps 22 are conductive end caps, and the two end caps 22 themselves provide the conductive parts 30 or have conductive parts 30, the support shaft 23 is a conductive support shaft, and the two conductive end caps 22 are electrically connected through the conductive support shaft 23.

[0075] Furthermore, the first sidewall 121a and the second sidewall 121b are provided with grooves 122 corresponding to the support shaft 23. Both ends of the support shaft 23 protrude to the outside of the two end caps 22 and can be installed into the grooves 122. Preferably, the electrical contact portion 40 is disposed in the groove 122 for direct contact and engagement with the support shaft 23. In other embodiments of this invention, the conductive portion 30 can also be disposed on the paper tube body 21; such as... Figures 9-10 As shown, the conductive part 30 is disposed in the middle of the cylindrical body 21, and the electrical contact part 40 is disposed on the peripheral wall 111 of the receiving part corresponding to the conductive part 30. When the consumable carrying member 20 is installed into the receiving part 11, it directly forms a contact engagement with the electrical contact part 40. Preferably, the peripheral wall 111 of the receiving part is specifically an arc shape adapted to the shape of the cylindrical body 21.

[0076] In other embodiments, such as Figure 11 As shown, the electrical contact part 40 can also be provided on the outer cover 13, and correspondingly, the conductive part 30 is provided at the end of the cylinder body 21 near the end cover 22 and facing the outer cover 13; further, as Figures 12-13 As shown, there can be two conductive parts 30, which are connected, for example, by a wire; correspondingly, there are also two electrical contact parts 40, which are connected, for example, by a wire. In use, the consumable carrier 20 is first installed into the receiving part 11, and then the outer cover 13 is assembled into place to complete the installation of the consumable carrier 20. At this time, the electrical contact part 40 provided on the inner side of the outer cover 13 forms a direct contact engagement with the conductive part 30 on the cylinder body 21.

[0077] In some other embodiments of this utility model, such asFigures 14-15 As shown, the conductive part 30 can also be provided on the end cap 22 and the cylinder body 21 at the same time. Correspondingly, the electrical contact part 40 is provided on the side wall 121, the peripheral wall 111 of the receiving part, or the outer cover 13, and thus forms a contact engagement with the two conductive parts 30.

[0078] It should be noted that the number of conductive parts 30 and electrical contacts 40 in the embodiments can be set according to actual needs, and there is no limitation on them here; for example, when only one conductive part 30 is provided, the conductive part 30 preferably has two or more electrical contacts so that it can cooperate with the electrical contact 40 to form a conductive circuit; when two or more conductive parts 30 are provided in the embodiments, the multiple conductive parts 30 are preferably connected to each other and cooperate with the electrical contact 40 respectively to form a conductive circuit.

[0079] Transformation 1

[0080] When the consumable carrier 20 is placed in the receiving part 11, the two side walls inside the receiving part 11 are configured as capacitors, and the capacitance between the receiving parts 11 changes.

[0081] This embodiment is another extension of the above-mentioned resistor voltage identification of different consumables, and another embodiment that uses the receiving part as a capacitor to detect the capacitance change between the receiving parts.

[0082] See Figure 17 When the consumable carrier component 20 is placed in the capacitor receiving portion 11, the capacitance of the receiving portion 11 changes after the consumable carrier component 20 is placed. At this time, after the power is turned on, the capacitor begins to charge or discharge. In one embodiment, the charging or discharging time required for the capacitor to reach a stable voltage value varies depending on the material of the consumable carrier component 20. The processor connects to the capacitor, obtains the charging or discharging time of the capacitor, and compares it with the information stored in the processor corresponding to specific times for different consumable carrier components 20. The ADC module continuously obtains the voltage value of the capacitor, and by calculating the time it takes for the current capacitor to reach a stable voltage, the model or parameters of the current consumable carrier component 20 can be determined. In another embodiment, a capacitance sensor can be connected to the circuit. The capacitance sensor obtains the capacitance change information at both ends of the receiving portion 11 and sends it to the processor. The processor compares the capacitance change with the values ​​of various consumable carrier components 20 stored internally to determine the model or parameters of the current consumable carrier component 20.
