Description

Technical Field

[0001] The present invention relates to the technical field of printing devices, and more particularly, to a substation label printing device. Background Art

[0002] As a key hub of the power system, a substation is equipped with a large number of various intelligent terminal screens, cables, control cabinets, etc. A variety of printing consumables need to be pasted on these cabinets to identify the device models and their functions. When pasting printing consumables in a substation, different contents need to be printed at any time according to the conditions of different substations and built-in components, and different sizes of printing consumable papers need to be selected for printing different built-in components. Currently, printing of printing consumables requires computer connection or wireless connection to a computer to achieve printing of different contents.

[0003] This often involves different sizes of printing consumable papers. For existing printing devices, after receiving the content of the printing consumables processed by a computer through a communication module, the printing device needs to be opened, the original printing consumable paper needs to be taken out and replaced with a new one before different sizes of printing consumables can be printed, and the operation is very troublesome. In particular, in the maintenance of printing consumables in a substation, more different sizes of printing consumables are often required rather than a large number of the same size of printing consumables. Therefore, how to quickly convert the size of the printing consumable paper and enable the printing component to quickly dock with different sizes of printing consumable papers is an urgent problem to be solved.

[0004] To solve the above problems, a substation label printing device is proposed. Summary of the Invention

[0005] To solve the above technical problems, a substation label printing device is provided, and this technical solution solves the problems raised in the above background art.

[0006] To achieve the above object, the present invention may adopt the following technical solutions:

[0007] The present invention provides a substation label printing device, including:

[0008] A base, on both sides of the top of which are fixedly connected with vertical walls, a clamping bin is formed between the two vertical walls, a paper bin assembly is arranged in the clamping bin, a cover plate is jointly clamped at the outer edges of the two vertical walls, two through holes are opened in the vertical part of the cover plate, a rotating shaft is fixedly connected to one end of the base away from the vertical wall, a housing is rotatably connected to the outside of the rotating shaft, a thermal printing head is fixedly connected to one end of the housing away from the vertical wall, a paper feeding assembly is arranged at one end of the housing close to the vertical wall, an extension arm is fixedly connected to one outer wall of the housing, and a spring telescopic rod is fixedly connected to one end of the extension arm away from the housing;

[0009] The paper bin assembly includes two paper feeders disposed in the paper clamping bin. The two sides of each paper feeder are slidably engaged with the vertical walls respectively. A protruding portion is fixedly connected to the bottom of each paper feeder. A third spring is fixedly connected to one end of the protruding portion close to the housing. A stop rod is fixedly connected to one end of the third spring close to the housing. Both ends of the stop rod are fixedly connected to the inner wall of the vertical wall respectively.

[0010] Furthermore, a paper supporting elastic piece is fixedly connected to the middle of the paper feeder, and a top plate is fixedly connected to the top of the paper feeder.

[0011] Furthermore, the paper transfer assembly includes two sliders which are respectively slidably connected to both sides of the bottom wall of the housing. A first double-shaft extension motor is disposed between the two sliders. The first double-shaft extension motor is fixedly connected to the middle of the bottom wall of the housing. Two output shafts of the first double-shaft extension motor are both fixedly connected with screw rods. The outer parts of the screw rods are respectively threadedly connected to the inside of the sliders.

[0012] Furthermore, a paper transfer table is fixedly connected above the inner sides of the sliders.

[0013] Furthermore, the paper transfer assembly further includes two reverse double-output gear boxes which are respectively fixedly connected to the tops of the sliders and are symmetrically arranged with respect to the first double-shaft extension motor. Two output shafts of each reverse double-output gear box are both fixedly connected with rubber rollers. The two rubber rollers connected to each reverse double-output gear box are set as a group. Each group of rubber rollers is arranged in parallel up and down. There is a certain included angle between the axial lines of the two groups of rubber rollers, and the opening direction of the included angle points to the paper clamping bin. Two input shafts of the two reverse double-output gear boxes are both fixedly connected with a second motor.

[0014] Among them, the lower rubber roller is correspondingly buried in the opening in the middle of the paper transfer table, and the top end of its roller surface is flush with the table surface of the paper transfer table.

[0015] Furthermore, the paper transfer assembly further includes a gantry. One end of the gantry close to the paper transfer table is rotatably connected to the top wall of the housing. A second double-shaft extension motor is fixedly connected to one side of the gantry. Two output shafts of the second double-shaft extension motor extend to the same width as the paper feeder. A paper rubbing wheel is fixedly connected to the outside of one output shaft of the second double-shaft extension motor, and the paper rubbing wheel is located inside the gantry. A first spring is fixedly connected to the middle of the top of the gantry. The top end of the first spring is correspondingly fixedly connected to the top wall of the housing.

[0016] A rubber table is slidably connected to the middle of one side of the paper feeder close to the paper transfer table. A second spring is fixedly connected to the bottom of the rubber table, and the bottom of the second spring is correspondingly fixed to the paper feeder.

[0017] Furthermore, arc-shaped convex platforms are fixedly connected to the tops of both sides of each paper feeder close to the paper transfer table. When the paper feeder slides below the paper rubbing wheel, the tops of the arc-shaped convex platforms cooperate with the two output shafts of the second double-shaft extension motor to be able to lift the paper rubbing wheel to avoid contacting the rubber table.

[0018] Further, the positions of the two paper feeders correspond to the positions of the two through holes one by one.

[0019] As described above, the features and advantages of a substation label printing device in the present invention are:

[0020] By loading different-sized printing consumables multiple times at once, it is possible to load different-sized printing consumable papers in the printing device at one time, without the problem that existing printing devices can only load one type of printing consumable paper, and it is more suitable for the maintenance of printing consumables in substations, where more different-sized printing consumables are often required rather than a large number of the same-sized printing consumables.

[0021] By aligning different-sized printing consumables, automatic replacement of the printing device without disassembly is achieved, solving the situation where when using existing printing devices, the printing device needs to be opened, the original printing consumable paper needs to be taken out and a new printing consumable paper needs to be replaced in order to print different-sized printing consumables. By quickly selecting a specified paper feeder, the operation of the previous printing components to dock with different-sized printing consumable papers becomes simpler and more efficient. Furthermore, when the printing device is connected to a computer, it can more effectively respond to print the matching content, eliminating the need to replace the printing device and temporarily replace the printing paper.

[0022] During the docking process, the two extended output ends of the second double-shaft motor are pushed by the arc-shaped convex platforms on both sides, driving the paper feed rollers to lift upward. When the paper feed rollers move relative to the paper feeder, they will not touch the printing consumable paper inside the paper feeder, avoiding the situation where the paper feed rollers push the printing consumable paper and thus affecting the stacking neatness of the printing consumable paper.

[0023] When exporting or feeding out the printing consumable paper, by using the vector component of the force of the rubber roller on the printing consumable paper, the printing consumable paper not only has the power to continue moving forward but also has the force to pull the printing consumable paper to both sides, making the printing consumable paper be forced to be flattened when exported, thus avoiding the situation of printing ghosting, skewing, and mutilation caused by warping, unevenness, etc. during the paper feeding process when the printing consumable paper enters the thermal printing head.

[0045] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0046] Refer to Figures 1-5 As shown, an embodiment of the present invention is provided, and a substation label printing device provided will be elaborated in detail below:

[0047] A substation label printing device includes a base 101, and vertical walls 102 are fixedly connected to both sides of the top thereof. Refer to Figure 3 , a clamping bin 103 is formed between the two vertical walls 102. A paper bin assembly is arranged in the clamping bin 103. A cover plate 104 is jointly clamped at the outer edges of the two vertical walls 102. Two through holes 105 are formed in the vertical part of the cover plate 104. A rotating shaft 106 is fixedly connected to one end of the base 101 away from the vertical wall 102. A housing 107 is rotatably connected to the outside of the rotating shaft 106. A thermal printing head is fixedly connected to one end of the housing 107 away from the vertical wall 102, and a paper feeding assembly is arranged at one end of the housing 107 close to the vertical wall 102. An extension arm 108 is fixedly connected to one outer wall of the housing 107. A spring telescopic rod 109 is fixedly connected to one end of the extension arm 108 away from the housing 107. The spring telescopic rod 109 is composed of a telescopic rod and a spring.

[0048] Refer to Figures 6-7 As shown, the paper bin assembly includes two paper feeding racks 301 arranged in the clamping bin 103. The two paper feeding racks 301 are respectively located on the upper and lower sides in the clamping bin 103. The two sides of the paper feeding rack 301 are respectively slidably matched with the vertical wall 102. Refer to Figure 5 and Figure 9As shown in the figure, protruding parts 308 are fixedly connected to the bottom of the paper feeder 301. One end of each protruding part 308 close to the housing 107 is fixedly connected to a third spring 307. One end of each third spring 307 close to the housing 107 is fixedly connected to a stop rod 306. Both ends of the stop rod 306 are fixedly connected to the inner wall of the vertical wall 102. In this embodiment, the elastic force of the third spring 307 is less than that of the spring telescopic rod 109.

[0049] Furthermore, referring to Figures 8-9 As shown in the figure, a paper supporting elastic piece 302 is fixedly connected to the middle of the paper feeder 301, and the paper supporting elastic piece 302 can have an upward force through its own elastic force. A top plate 303 is fixedly connected to the top of the paper feeder 301. The paper supporting elastic piece 302 is made of an elastic metal material such as stainless steel. Its installation state is that one end is fixedly connected to the paper feeder 301 and the other end tilts upward. In this way, when pressing down on the paper supporting elastic piece 302, the stacked printing consumable papers can be constantly pushed upward by using elastic deformation, so as to achieve the purpose of automatic paper feeding.

[0050] In this embodiment, referring to Figures 10-12 , the paper transfer assembly includes two sliders 201. The two sliders 201 are respectively slidably connected to both sides of the bottom wall of the housing 107. A first double-shaft extension motor 203 is arranged between the two sliders 201. The first double-shaft extension motor 203 is fixedly connected to the middle of the bottom wall of the housing 107. Both output ends of the first double-shaft extension motor 203 are fixedly connected to screw rods 204. The outer parts of the screw rods 204 are respectively threadedly connected to the inside of the sliders 201.

[0051] In this embodiment, paper transfer platforms 202 are fixedly connected above the inner sides of the sliders 201.

[0052] Furthermore, the paper transfer assembly further includes two reverse double-output gearboxes 205. The two reverse double-output gearboxes 205 are respectively fixedly connected to the tops of the sliders 201, and the two reverse double-output gearboxes 205 are symmetrically arranged on both sides of the first double-shaft extension motor 203. Both output ends of each reverse double-output gearbox 205 are fixedly connected to rubber rollers 206. The two rubber rollers 206 connected to each reverse double-output gearbox 205 are set as a group. Each group of rubber rollers 206 is arranged parallel up and down. There is a certain included angle between the axial lines of the two groups of rubber rollers 206, and the opening direction of the included angle points to the clamping bin 103. Both input ends of the two reverse double-output gearboxes 205 are fixedly connected to a second motor 207.

[0053] Among them, referring to Figure 12 , the lower rubber roller 206 is correspondingly buried in the opening in the middle of the paper transfer platform 202, and the top of its roller surface is flush with the table surface of the paper transfer platform 202.

[0054] In this embodiment, the included angle between the axial lines of the two groups of rubber rollers 206 is preferably 90°.

[0055] Further, referring to Figure 13 , the paper transfer assembly further includes a gantry 208. One end of the gantry 208 close to the paper transfer table 202 is rotatably connected to the top wall of the housing 107. A second double-shaft motor 210 is fixedly connected to one side of the gantry 208, and the two output ends of the second double-shaft motor 210 extend to be consistent with the width of the paper feed rack 301. A paper rubbing wheel 209 is fixedly connected to the outside of one output end of the second double-shaft motor 210, and the paper rubbing wheel 209 is located inside the gantry 208. A first spring 211 is fixedly connected to the middle of the top of the gantry 208, and the top end of the first spring 211 is fixedly connected to the top wall of the housing 107 correspondingly;

[0056] Referring to Figures 14-15 , a rubber table 304 is slidably connected to the middle of one side of the paper feed rack 301 close to the paper transfer table 202. A second spring 305 is fixedly connected to the bottom of the rubber table 304, and the bottom of the second spring 305 is fixed to the paper feed rack 301 correspondingly;

[0057] Among them, the friction between the rubber table 304 and the printing consumable paper is greater than the friction between two sheets of printing consumable paper, and the friction between the rubber table 304 and the printing consumable paper is less than the friction between the paper rubbing wheel 209 and the printing consumable paper.

[0058] In this embodiment, when the topmost printing consumable paper electrostatically adsorbs the lower printing consumable paper, driven by the paper rubbing wheel 209, they will leave the paper feed rack 301 together. When the lower printing consumable paper contacts the rubber table 304, since the friction between it and the printing consumable paper is greater than the friction between two sheets of printing consumable paper, and the friction between the rubber table 304 and the printing consumable paper is less than the friction between the paper rubbing wheel 209 and the printing consumable paper, the relative movement between the printing consumable papers can be realized, the interception of the lower printing consumable paper can be achieved, and the situation of repeated paper feeding can be avoided. The cooperation between the paper rubbing wheel 209 and the rubber table 304 is a direct application of the prior art, and its technical principle will not be elaborated here.

[0059] Further, referring to Figures 16-17 , arc-shaped convex platforms 309 are fixedly connected to the tops of both sides of each paper feed rack 301 close to the paper transfer table 202. When the paper feed rack 301 slides below the paper rubbing wheel 209, the tops of the arc-shaped convex platforms 309 cooperate with the two output ends of the second double-shaft motor 210, and can jack up the paper rubbing wheel 209 to avoid contact with the rubber table 304.

[0060] Referring to Figure 5 , the positions of the two paper feed racks 301 correspond to the positions of the two through holes 105 one by one, which can facilitate the smoothness when the spring telescopic rod 109 pushes the paper feed rack 301.

[0061] Further, in this embodiment, the printing component cooperating with the thermal print head further includes a control key fixedly connected to the top of the housing 107. The control key is electrically connected to the thermal print head, the first double-shaft motor 203, the second double-shaft motor 210, and the second motor 207. Among them, the printing component further includes a processor module, a sensor, a communication module, a battery module, as well as a display screen and a speaker component. Its basic working logic is that the printing consumable information about the substation to be printed in the computer is transmitted to this printing device through the communication module. Then, a suitable paper feed tray 301 is manually selected. Through the control key, the processor module, in cooperation with the display screen and the speaker component, processes the information. The battery module supplies power to all electrical components. Then, the paper feed roller 209, the rubber roller 206, etc. are controlled to transmit a single sheet of printing consumable paper to the position of the thermal print head. When the sensor is triggered during the paper feeding process of the printing consumable paper, the processor module controls the thermal print head to start printing. The above printing working technical principles all adopt existing technologies and will not be elaborated here.

[0062] Combined with the above embodiments, the following is the entire working process and working principle of the above embodiments:

[0063] The working state is as follows: First, stack the printing consumable papers of different sizes neatly, and then send them into each paper feed tray 301 respectively. Specifically, one end of the printing consumable paper is inserted into the paper feed tray 301, and the paper support spring piece 302 is pressed down until one end of the printing consumable paper contacts and aligns with the rubber table 304. In this embodiment, during the production process, baffles are deliberately designed inside the paper feed tray 301. For the specific structure, please refer to Figure 9 , that is, at both sides of the end of the paper feed tray 301 away from the rubber table 304, an L-shaped baffle is provided on each side. The printing consumable paper can be stably restricted through the cooperation between the two baffles. At the same time, by designing the distance between the two baffles and the distance between the two baffles and the rubber table 304, printing consumable papers of different sizes can be adapted. The protruding baffles can limit the placement space of the printing consumable paper. This belongs to the prior art and can achieve the purpose of limiting and stabilizing the printing consumable paper. And after the printing consumable paper is limited, it should be located at the middle position in the width direction of the paper feed tray 301, and the cover plate 104 is snapped in place.

[0064] The user supports the top of the base 101 with one hand and compresses the spring telescopic rod 109 at one end of the extension arm 108 with the other hand, and then lifts the extension arm 108 to rotate the housing 107 by a certain angle until the telescopic part of the spring telescopic rod 109 is aligned with a selected paper feeder 301, and then releases the spring telescopic rod 109 to make it enter the clamping compartment 103 from the corresponding through hole 105, and then, under the release of its potential energy, the corresponding paper feeder 301 is slid inside the clamping compartment 103 and moves toward the thermal print head. At this time, the spring 307 is compressed correspondingly through the protrusion 308 and the blocking rod 306. When the paper feeder 301 slides below the pickup wheel 209, the arc bosses 309 on both sides will first contact the second double The output end of the extended shaft motor 210 is installed on the door frame 208, and then when the paper feeding rack 301 continues to slide, the arc boss 309 pushes the two ends of the extended output shaft of the second double-axle extension motor 210, thereby driving the paper pickup wheel 209 to move upward and compressing the spring 1 211 at the same time until the paper feeding rack 301 slides into place, that is, it contacts the paper transfer table 202. At this time, the extended output end of the second double-axle extension motor 210 ends the movement stroke along the top of the arc boss 309, and the paper pickup wheel 209 falls and resets under the release of the potential energy of the spring 1 211, so that the bottom of the roller surface is pressed on the topmost printing consumables paper, thereby preventing the paper pickup wheel 209 from affecting the stacking neatness of the printing consumables paper.

[0065] By starting the first dual-axle motor 203, the screw 204 is driven to rotate, so that the sliders 201 on both sides, together with the paper transfer platform 202 and the rubber roller 206, move closer or farther away synchronously until the distance between the rubber rollers 206 matches the width of the printing consumable paper. After the above printing preparation work is completed, the information content transmitted by the computer is printed.

[0066] Then the controller starts the second dual-axis extension motor 210, which in turn drives the paper pickup wheel 209 to rotate. Since the friction between the downwardly pressed paper pickup wheel 209 and the printing consumables paper is relatively large, the uppermost layer of printing consumables paper will be driven to move onto the paper transfer platform 202. Since the friction between the rubber platform 304 and the printing consumables paper is greater than the friction between the two printing consumables paper, and the friction between the rubber platform 304 and the printing consumables paper is less than the friction between the paper pickup wheel 209 and the printing consumables paper, the paper pickup wheel 209 cooperates with the rubber platform 304 pushed upward by the spring 1 211, and can only drive one printing consumables paper to leave the paper feed rack 301 at a time.

[0067] The front end of the printing consumable paper leaving the paper feed rack 301 will be pushed on the paper transfer platform 202, and then when entering between the rubber rollers 206, the reverse dual output gear box 205 is driven by the motor 207 to drive the upper and lower rubber rollers 206 to rotate in the opposite direction, so as to use the static friction between the rubber rollers 206 and the printing consumable paper to perform a secondary paper transfer action on the printing consumable paper. Among them, since there is a certain angle between the rotation axes of the two groups of rubber rollers 206, and the opening direction of the angle points to the paper bin assembly, therefore, by splitting the force of the rubber rollers 206 on the printing consumable paper, that is, performing a force vector analysis, it can be seen that the rubber rollers 206 not only have the power to continue to transfer the paper forward, but also have the force to pull the printing consumables to both sides in the perpendicular paper transfer direction. This makes the printing consumable paper forced to be "pulled flat" to both sides when passing through the rubber rollers 206, thereby avoiding the printing of double images, skewness, and incompleteness caused by warping and inequality when the printing consumable paper enters the thermal print head.

[0068] When the printing consumables paper is continuously transmitted on the paper conveyor 202, it will trigger the sensor near the thermal print head, and then inform the thermal print head to start working through the feedback signal. When the printing consumables paper enters the thermal print head, the thermal print head self-heats at the specified coordinate point, thereby causing the corresponding coordinate point of the printing consumables paper to react, and then the required printing consumables content is pieced together through the reaction marks left behind. After printing is completed, the printing consumables are output from the printing outlet, and at this point, a printing job is completely completed.

[0069] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, the elements defined by the sentence "including one..." do not exclude the presence of other identical elements in the process, method, article or device including the elements.
