Description

Technical Field

[0001] This utility model belongs to the technical field of thermal printer cartridges, specifically relating to a thermal printer cartridge with a grounded conductive structure. Background Technology

[0002] The existing thermal printer core is the core component installed inside the thermal printer for printing. Its working principle is that a semiconductor heating element is installed on the print head. After the print head is heated and comes into contact with the thermal paper, the desired pattern can be printed. Existing thermal printer cartridges, when installed, have their mounting plates directly closed to the bottom of the frame, which is not convenient for reinforcement. Furthermore, the hooks at the top of the mounting plate do not easily make tight contact with the mounting sleeve surface for secure installation, making them prone to shaking and instability under operational stress. This instability can even reduce printing quality and affect the anti-loosening and reinforcement of the thermal printer cartridge for the frame and rollers during installation. Therefore, this invention proposes a thermal printer cartridge with a grounded conductive structure. Utility Model Content

[0003] The purpose of this utility model is to provide a thermal printer cartridge with a grounded conductive structure to solve the problems mentioned in the background art, where the mounting plate is directly closed to the bottom of the frame after installation, which is not convenient for reinforcement. At the same time, the hooks at the top of the mounting plate are not easy to make tight contact and reinforce the installation when they are engaged with the surface of the mounting sleeve, which makes it easy to shake and be unstable when subjected to force during operation, and even reduce the printing effect when unstable.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a thermal printer core with a grounded conductive structure, comprising a frame and a mounting sleeve. An mounting shaft is engaged with one side of the bottom of the frame. An mounting plate is mounted inside the frame via the mounting shaft. Hooks are integrally provided on both sides of the mounting plate. Three main compression springs are equidistantly fixed to the bottom of the mounting plate. A heat sink is fixed to the top of each of the three main compression springs. A thermal sheet is fixed to the upper surface of the heat sink. The end of the heat sink is slidably connected to the end of the frame. Conductive copper foil is provided on the side of the thermal sheet. An anti-loosening reinforcement mechanism is provided at the connection between the lower surface of the frame and the middle of the mounting plate. A grounding mounting mechanism is provided on one side of the conductive copper foil. The anti-loosening reinforcement mechanism includes a limiting closing component located at the midpoint between the lower surface of the frame and the lower surface of the mounting plate. Both ends of the limiting closing component are provided with elastic locking components. A pulling adjustment component is provided at the connection between the two sets of elastic locking components. A pressing component is provided at the end connection between the mounting sleeve and the hook. The grounding installation mechanism includes a uniform grounding installation assembly disposed on one side of the conductive copper foil.

[0005] Preferably, the mounting sleeve is engaged with the end of the frame via the hook, and a rubber roller is mounted at the connection of the two mounting sleeves via a bearing, with a driven gear fixed at the end of the rubber roller.

[0006] Preferably, a motor is fixed to the inner side of one end of the frame, a drive gear is fixed to the end of the motor on the surface of the frame, a driven gear two is mounted on the side of the drive gear at the end of the frame via a rotating shaft, a driven gear three is meshed on one side of the driven gear two, the driven gear three is mounted to the side of the frame via a rotating shaft, the driven gear three meshes with the driven gear one, and a cover plate is snapped onto the end surface of the frame.

[0007] Preferably, the limiting closure assembly includes a connecting plate integrally disposed at the middle position of the lower surface of the mounting plate, and a buckle groove is provided at the middle position of the lower surface of the frame, and the connecting plate is embedded in the buckle groove.

[0008] Preferably, the elastic locking assembly includes limiting grooves formed at both ends of the connecting plate, limiting heads are limited inside the limiting grooves, and locking holes that engage with the limiting heads are formed at both ends of the locking groove. An auxiliary compression spring is fixed at the connection between the tail end of the limiting head and the end of the limiting groove.

[0009] Preferably, the pull adjustment assembly includes a slide groove located in the middle of the connecting plate, a slider sliding inside the slide groove, and control blocks integrally provided on both sides of the slider that slide with the sides of the slide groove. A pull rope is fixed to the connection between the side of the slider and the end of the limiting clip by screws, and the pull rope passes through the interior of the auxiliary compression spring.

[0010] Preferably, the clamping assembly includes a clamping block integrally disposed at the end of the hook, and the surface of the mounting sleeve is provided with a clamping groove, wherein the clamping block is in pressure contact with the clamping groove.

[0012] Compared with the prior art, the beneficial effects of this utility model are: By designing an anti-loosening reinforcement mechanism, the mounting plate can be closed inside the frame, and then the connecting plate can be closed inside the latching groove. When the slider is released, the auxiliary compression spring deforms, causing the limit clamp head to elastically engage inside the clamping hole, thus reinforcing the connection plate and the inside of the latching groove. This also facilitates the anti-loosening reinforcement of the mounting plate to the lower surface of the frame after installation. When the hook engages, the pressure block engages inside the pressure groove to reinforce the mounting sleeve. The printer cartridge is less prone to instability when subjected to force during use, resulting in more stable and accurate printing. This improves the anti-loosening reinforcement between the frame and the mounting plate when the printer cartridge is installed and in use. Attached Figure Description

[0015] Please see Figures 1 to 9 This utility model provides a technical solution: a thermal printer core with a grounded conductive structure, including a frame 101 and a mounting sleeve 106. A mounting shaft 1021 is engaged with one side of the bottom of the frame 101. A mounting plate 102 is mounted inside the frame 101 via the mounting shaft 1021. Hooks 109 are integrally provided on both sides of the mounting plate 102. The mounting sleeve 106 is engaged with the end of the frame 101 via the hooks 109. A rubber roller 107 is mounted at the connection of the two mounting sleeves 106 via a bearing. Three main compression springs 103 are fixed at equal intervals at the bottom of the mounting plate 102. A heat sink 104 is fixed at the top of the three main compression springs 103. A thermal sheet 105 is fixed on the upper surface of the heat sink 104. The end of the heat sink 104 is slidably connected to the end of the frame 101. A conductive copper foil 108 is provided on the side of the thermal sheet 105. A driven gear 1011 is fixed to the end of the rubber roller 107. A motor 1013 is fixed to the inner side of one end of the frame 101. A drive gear 1014 is fixed to the end of the motor 1013 on the surface of the frame 101. A driven gear 1015 is mounted on the side of the drive gear 1014 at the end of the frame 101 via a rotating shaft. A driven gear 1016 meshes with one side of the driven gear 1015. The driven gear 1016 is mounted to the side of the frame 101 via a rotating shaft and meshes with the driven gear 1011. A cover plate 1012 is fitted onto the end surface of 101. When the motor 1013 is powered on, it drives the drive gear 1014 to rotate. When the drive gear 1014 rotates, it meshes with the driven gear 1015 and the driven gear 1016 on the surface of the driven gear 1011, which drives the rubber roller 107 to rotate inside the mounting sleeve 106. This facilitates the rotation and drives the white paper to contact the thermal sheet 105 for printing. An anti-loosening reinforcement mechanism is provided at the middle connection between the lower surface of the frame 101 and the mounting plate 102. A grounding installation mechanism is provided on one side of the conductive copper foil 108. The anti-loosening reinforcement mechanism includes a limiting closure component located at the midpoint between the lower surface of the frame 101 and the lower surface of the mounting plate 102. Both ends of the limiting closure component are provided with elastic locking components, and a pulling adjustment component is provided at the connection between the two sets of elastic locking components. A pressing component is provided at the end connection between the mounting sleeve 106 and the hook 109. After installation, the mounting plate 102 and the frame 101 can be closed, and the anti-loosening reinforcement mechanism can reinforce the installation and drive the hook 109 to press and fix the mounting sleeve 106.

[0016] To facilitate the use of the limiting closure assembly for closing and reinforcing the mounting plate 102 and the frame 101, in this embodiment, preferably, the limiting closure assembly includes a connecting plate 1023 integrally disposed at the middle position of the lower surface of the mounting plate 102. A fastening groove 1022 is provided at the middle position of the lower surface of the frame 101, and the connecting plate 1023 is embedded inside the fastening groove 1022. When the mounting plate 102 is closed at the bottom of the frame 101, the connecting plate 1023 can be closed inside the fastening groove 1022, facilitating the closing and installation.

[0017] To facilitate the locking of the connecting plate 1023 into the slot 1022 and prevent loosening, in this embodiment, preferably, the elastic locking assembly includes limiting grooves 10201 at both ends of the connecting plate 1023. A limiting head 1020 is positioned inside the limiting groove 10201. The slot 1022 has locking holes 1029 at both ends that engage with the limiting head 1020. An auxiliary compression spring 1028 is fixed at the connection between the tail end of the limiting head 1020 and the end of the limiting groove 10201. After the connecting plate 1023 is locked into the slot 1022, the auxiliary compression spring 1028 deforms, causing the limiting head 1020 to elastically engage into the locking hole 1029 for secure installation, facilitating locking and preventing instability during operation.

[0018] To facilitate the simultaneous opening of the two limit clamps 1020 by pulling the adjustment assembly, in this embodiment, preferably, the adjustment assembly includes a slide groove 1027 located in the middle of the connecting plate 1023. A slider 1024 slides inside the slide groove 1027. Control blocks 1026 that slide with the sides of the slide groove 1027 are integrally provided on both ends of the slider 1024. A pull rope 1025 is fixed to the connection between the side of the slider 1024 and the end of the limit clamp 1020 by screws. The pull rope 1025 passes through the interior of the auxiliary compression spring 1028. The slider 1024 can be pulled and adjusted inside the slide groove 1027 by the control blocks 1026. When the slider 1024 is pulled, the pull rope 1025 drives the two limit clamps 1020 to be pulled and adjusted simultaneously.

[0019] In order to facilitate the secure engagement of the hook 109 with the mounting sleeve 106 by means of a clamping assembly, in this embodiment, preferably, the clamping assembly includes a clamping block 1061 integrally disposed at the end of the hook 109, and a clamping groove 1062 is formed on the surface of the mounting sleeve 106. The clamping block 1061 and the clamping groove 1062 are pressed into contact. When the hook 109 is engaged with the surface of the mounting sleeve 106, it causes the clamping block 1061 to be driven into the interior of the clamping groove 1062, which facilitates the clamping and reinforcement of the installation and makes the operation more stable under force.

[0020] The grounding installation mechanism includes a uniform grounding installation component set on one side of the conductive copper foil 108. After the conductive copper foil 108 is energized and installed, the grounding installation mechanism can be used to uniformly ground and conduct electricity to the conductive copper foil 108, resulting in better conductive installation effect.

[0021] To facilitate uniform grounding of the conductive copper foil 108 using a uniform grounding installation assembly, and to provide grounding protection through two auxiliary grounding plates 1084 in the event of damage to one of the conductive copper foils 108, in this embodiment, preferably, the uniform grounding installation assembly includes a grounding wire 1081 disposed on one side of the conductive copper foil 108. The end of the grounding wire 1081 is integrally disposed on a horizontal integral plate 1082. Three auxiliary grounding plates 1084 are integrally disposed on the end of the horizontal integral plate 1082. The auxiliary grounding plates 1084 have mounting holes 1083 inside, through which screws can be passed to fix the auxiliary grounding plates 1084 to ground. Therefore, during use after installation, grounding protection is provided through the grounding wire 1081 and the auxiliary grounding plates 1084. In the event of damage to one grounding wire 1081, auxiliary grounding protection is provided through the two auxiliary grounding wires 1084.

[0022] The working principle and usage process of this utility model: When using this thermal printer core with a grounded conductive structure, it first contacts and fixes itself to the mounting point inside the printer through the frame 101. The conductive copper foil 108 is connected to the circuit board inside the printer. At this time, the motor 1013 is powered on and drives the drive gear 1014 to rotate. When the drive gear 1014 rotates, it drives the rubber roller 107 to rotate inside the mounting sleeve 106 through the meshing of the driven gear 1015 and the driven gear 1016 on the surface of the driven gear 1011. At the same time, inside the mounting plate 102, the main clamping spring 103 drives the heat sink 104 and the thermal sheet 105 to press tightly against the surface of the rubber roller 107, and white paper is continuously fed between the surface of the thermal sheet 105 and the rubber roller 107 for printing. Before use, during installation, the mounting sleeve 106 installed at the end of the rubber roller 107 is closed at the end of the frame 101. When the mounting plate 102 is rotated and closed on the inner surface of the frame 101 by the mounting shaft 1021, the finger touches the slider 1024 and pulls it to the bottom. The pull rope 1025 drives the limit clip head 1020 to be embedded in the limit groove 10201. When the mounting plate 102 is pressed, the hooks 109 at both ends engage with the surface of the mounting sleeve 106 and drive the pressure block 1061 to engage with the inside of the pressure groove 1062, which facilitates the installation of the mounting sleeve 106. After the hooks 109 are fully engaged, the connecting plate 1023 on the lower surface of the mounting plate 102 is closed in the inside of the buckle groove 1022. When the slider 1024 is released again, the auxiliary compression spring 1028 deforms, causing the limit clip 1020 to elastically engage inside the clip hole 1029. At the same time, the slider 1024 returns to its original position, thus facilitating the internal reinforcement installation of the connecting plate 1023 and the buckle groove 1022. It also facilitates the anti-loosening reinforcement installation of the mounting plate 102 to the lower surface of the frame 101 after installation. Simultaneously, it presses and reinforces the mounting sleeve 106 and the frame 101, making the printer core less prone to instability under stress during use, resulting in more stable and accurate printing. It also improves the anti-loosening reinforcement between the frame 101 and the mounting plate 102 when the printer core is installed and in use. During disassembly, the mounting plate 102 can be opened by sliding it against the slider 1024 when the lower surface is moved, facilitating internal disassembly operations. Finally, when the printer cartridge is installed and in use, after the conductive copper foil 108 connects to the chip inside the printer, the three auxiliary grounding pieces 1084 on one side of the conductive copper foil 108 contact the ground. The screws penetrate the interior of the horizontal integrated plate 1082 to connect the auxiliary grounding pieces 1084 to the grounding wire 1081, which facilitates the installation of grounding protection. This allows the static electricity to be transferred to the ground and used safely. If one auxiliary grounding piece 1084 becomes loose or is damaged, it can also be grounded and protected by the other two grounding wires 1081, improving the convenience of uniform grounding auxiliary installation when the printer cartridge is installed and used.
