Description

Technical Field

[0001] The present application relates to the technical field of line number printers, and in particular to a microcomputer line number printer. Background Art

[0002] A cable number printer, also known as a cable number printer or a numbering machine, is a device that can print characters on materials such as PVC tubing, heat shrink tubing, and self-adhesive labels. A cable number printer generally uses thermal transfer printing technology to send the data information to be printed to the thermal transfer print head through the processing chip on the circuit board, thereby completing the printing on the material.

[0003] The line number printer is mainly used for marking the secondary lines of electric control and power distribution equipment. It is a special device for marking the wiring of electric control, power distribution equipment and integrated wiring projects. It can meet the needs of power plants, electrical equipment factories, substations, and the electric power industry for distinguishing wires and markings. It is widely used in the marking fields of switches, locomotives, machine tools, electric power, telecommunications, medicine, steel and other industries.

[0004] During the printing process of the existing wire gauge printer, the curved wire gauge embryo tube needs to be flattened before printing. However, the existing wire tube is relatively hard and difficult to be flattened by the roller, so the wire tube needs to be pre-processed.

[0005] For example, the patent with publication number CN 217415275U specifically discloses a feeding and discharging device of a wire number printer. The patent sets a heating unit at the input end of the wire number printer. The heating unit is set on a heating chamber. The heating unit can generate hot air to soften the wire tube. The heat source does not directly act on the wire tube, which can prevent the wire tube from being overheated and deformed. The softened wire tube is easy to flatten, and the characters on the wire tube are clearer.

[0006] However, during the implementation of the above patent, impurities attached to the wire tube are more easily separated from the wire tube after heating, making the wire tube more susceptible to the influence of impurities during printing, thereby affecting the printing effect. If the impurities fall off during printing, they will accumulate in the printer, which may affect the performance of the printer. Therefore, it is necessary to provide a microcomputer wire number printer to solve the above problems.

[0044] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0045] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present application.

[0046] Embodiment 1:

[0047] This embodiment mainly describes the structure and working principle of the line number printer, specifically:

[0048] like Figure 1-Figure 3 As shown, the present application provides a microcomputer line number printer, including a line number machine 1, the line number machine 1 has a base 11, the base 11 is the main body of the line number machine 1, can be placed on the table in the working area, and a printing component (not shown in the figure) is arranged inside the base 11, the printing component has a high-precision print head, and can adapt to high-precision printing operations;

[0049] At the same time, an operation panel 13 for input is provided on the base 11, and buttons are provided on the operation panel 13, wherein the operation panel 13 is designed to be inclined, so that the user can easily operate the buttons in a standing or sitting state. The operation panel 13 is equipped with an independent numeric keyboard and combination function keys, and the operation is simple and convenient. The user can directly input text, numbers and symbols through the keyboard;

[0050] A screen 14 is provided on the base 11. The screen 14 is a color high-definition LCD display screen, so that the screen 14 displays clearly and intuitively, and can display printing content, parameter settings, error messages, and print quantity. It also supports multiple language selections, and users can switch the display language of the screen 14 according to their needs.

[0051] In addition, a pipe inlet (not shown in the figure) and a pipe outlet 12 are respectively provided at both ends of the base 11. The pipe inlet is used to introduce the wire tube 4 so as to print the wire tube 4. At the same time, the printed wire tube 4 is exported through the pipe outlet 12 for subsequent use.

[0052] In summary, when the wire tube 4 needs to be printed, the wire tube 4 is introduced from the tube inlet, and then the printing parameter setting interface is entered on the operation panel 13;

[0053] In the print parameter setting interface, users can adjust various print parameters according to actual needs. For example: select the print mode (high speed / low speed), set the font, text height, text style (bold, italic, underline), character spacing and line spacing, print direction (horizontal / vertical), print density, number of copies, etc. The line number machine supports a variety of text heights, text widths (standard, condensed, expanded), character spacing (standard, condensed, widened) and line spacing adjustments; has the function of selecting the printing direction (vertical, horizontal); the paragraph length can be automatically adjusted according to the content, or it can be fixed. If it exceeds the set value, an error will be prompted; it has a continuous printing function, and the number of continuous prints can be set to improve printing efficiency; it can also set special effects such as underlining, framing, and continuous numbers at the bottom of the paragraph; it has a preview function, and users can check and confirm the print content before printing to avoid wasting consumables; selection of printing mode (high speed / low speed);

[0054] At the same time, during the parameter adjustment process, the display screen previews the printing effect in real time, and the user can intuitively see the impact of parameter changes on the printing effect, making it easier to make adjustments;

[0055] In the selection of printing mode, you can choose the following three modes:

[0056] 1. Edit directly on the line number machine 1. Use the letters, numbers, and symbols on the operation panel 13 to directly input the content to be printed. You can also use function key combination keys (such as delete, insert, copy and paste). During the editing process, you can call the built-in symbol library at any time to quickly insert common symbols (such as electrical symbols, arrows, lines, etc.). It also supports Chinese pinyin and English uppercase and lowercase switching.

[0057] 2. Edit with computer software and then transfer for printing. Install the line number identification editing software (specially developed supporting software) that is compatible with the line number machine 1 on the computer; open the software, select the model corresponding to the line number machine 1, and connect the computer to the line number machine 1 via the USB interface; edit the line number identification content in the software. The software also has a database function and can be directly imported into Excel tables, which is convenient and fast; after editing, send the designed content to the line number machine 1 for printing. After the printer receives the data, it prints according to the pre-set printing parameters.

[0058] 3. Print via USB flash drive. Save the edited data on the computer to the USB flash drive. Insert the USB flash drive into the USB interface on the line number machine 1 to read the print data. The line number machine 1 automatically detects the compatibility and files of the device. The user selects the corresponding template on the operation panel 13 for printing. At the same time, the user can also copy the template to the USB flash drive directly on the line number machine 1.

[0059] After the mode selection is completed, the printing function can be started and the wire tube 4 can be printed. The printed wire tube 4 can be exported from the outlet 12 for subsequent use.

[0060] During the printing process of the wire number machine 1, the curved wire number embryo tube needs to be flattened before printing, but the existing wire tube 4 is relatively hard and difficult to be flattened by the roller, so the wire tube 4 needs to be pre-processed;

[0061] To solve this problem, Figure 3-Figure 5 As shown, a heating mechanism 2 is provided at the pipe inlet of the line number machine 1, and the heating mechanism 2 includes a second connecting portion 27 connected to the pipe inlet, and the end of the second connecting portion 27 away from the line number machine 1 is connected to a heating box 21, and the end of the heating box 21 away from the second connecting portion 27 is connected to a first connecting portion 26, and a limiting cylinder 28 is threadedly connected to the first connecting portion 26. It should be noted that a threaded portion 281 is provided at the end of the limiting cylinder 28 close to the first connecting portion 26, and an internal thread (not shown in the figure) is provided on the first connecting portion 26, so that the limiting cylinder 28 can be installed on the first connecting portion 26 through the threaded portion 281, so that when the wire tube 4 enters the heating box 21 through the limiting cylinder 28, it can be heated to soften the wire tube 4, so as to facilitate subsequent flattening printing, and a sealing ring 29 is provided at the other end of the limiting cylinder 28, and the inner diameter of the sealing ring 29 matches the outer diameter of the wire tube 4, so as to seal one end of the heating box 21;

[0062] In this embodiment, because the limiting cylinder 28 is detachably arranged, limiting cylinders 28 of different sizes can be selected according to the diameter of the wire tube 4, thereby being suitable for printing wire tubes 4 of different diameters;

[0063] The second connection portion 27 is detachably mounted at the pipe inlet of the line numbering machine 1, so that the heating mechanism 2 can be disassembled when not in use to be placed separately from the line numbering machine 1;

[0064] Continue to refer Figure 3-Figure 4 The upper end of the heating box 21 is connected to an air inlet cylinder 22, and a heating wire 23 is arranged inside the air inlet cylinder 22. When the heating wire 23 is energized, the airflow passing through the air inlet cylinder 22 and entering the heating box 21 can be heated, thereby softening the wire tube 4.

[0065] At the same time, a pump body 24 is fixedly installed on the side of the heating box 21, and the input end of the pump body 24 is connected to the bottom of the heating box 21, so that when the pump body 24 is working, the air flow can pass through the air inlet cylinder 22 for heating, then enter the heating box 21, and then be led out from the heating box 21. During the movement of the air flow, the heating box 21 can be filled to heat the wire tube 4 in all directions;

[0066] Furthermore, because the heating box 21 is non-sealedly connected to the wire numbering machine 1, the heat generated by the wire numbering machine 1 during operation can also enter the heating box 21. On the one hand, the wire numbering machine 1 can be cooled, and on the other hand, the heat emitted by the wire numbering machine 1 can also enter the wire numbering machine 1, thereby doubly heating the wire tube 4 to increase the heating effect of the wire tube 4.

[0067] Embodiment 2:

[0068] During the heating process of the wire tube 4, the impurities attached to the wire tube 4 are more easily separated from the wire tube 4 after heating, so that the wire tube 4 is more easily affected by the impurities during printing, thereby affecting the printing effect, and if the impurities fall off during printing, they will accumulate in the wire number machine 1, which may affect the performance of the wire number machine 1;

[0069] In order to solve the above problems, Figure 7-Figure 9 As shown, a cleaning mechanism 5 is provided inside the heating box 21, and the cleaning mechanism 5 is used to scrape off impurities attached to the wire tube 4. The cleaning mechanism 5 includes a cleaning ring 51 sleeved on the outer ring of the wire tube 4. The cleaning ring 51 is provided in a half ring, so that two groups of cleaning rings 51 are combined into a full ring to wrap the wire tube 4.

[0070] At the same time, first countersunk holes 511 are provided on the end surfaces of the cleaning rings 51 that are close to each other, and third springs 59 are fixedly installed in the first countersunk holes 511, so that the two groups of cleaning rings 51 are connected to each other through the third springs 59, and due to the action of the third springs 59, in the initial state, the two groups of cleaning rings 51 are close to each other and closely attached to the line tube 4, and the two groups of cleaning rings 51 are suitable for being separated from each other under the action of external force;

[0071] Bosses 52 are provided on both sides of the cleaning ring 51. A vertical slide rail 56 is provided on one side of the boss 52 close to the first connection portion 26. A slider 54 is slidably provided on the slide rail 56. A first spring 53 is fixedly installed between the slider 54 and the interior of the heating box 21. Thus, in the initial state, the cleaning ring 51 is located on the wire tube 4 close to the first connection portion 26 under the action of the first spring 53. For the convenience of description, the position of the cleaning ring 51 at this time is defined as the first position.

[0072] Continue to refer Figure 7-Figure 9, multiple groups of cleaning parts 55 are arranged in the inner ring of the cleaning ring 51, and the cleaning parts 55 are elastically arranged, so that when the two groups of cleaning rings 51 are in close contact with the wire tube 4, the multiple groups of cleaning parts 55 are squeezed and in close contact with the wire tube 4, thereby increasing the friction between the cleaning ring 51 and the wire tube 4. At this time, if the wire tube 4 is pushed toward the printing position of the wire number machine 1 under the action of external force, the cleaning ring 51 will be pushed synchronously with the wire tube 4;

[0073] When the cleaning ring 51 arrives at a position far away from the first position along with the wire tube 4 (for the convenience of explanation, this position can be defined as the second position), the two groups of cleaning rings 51 are separated from each other by a fixed distance (the reason for the separation is explained below), so that the cleaning portion 55 is reset and contacts the wire tube 4, while the inner ring of the cleaning ring 51 is separated from the wire tube 4. At this time, due to the reduction of friction and the restoring force of the first spring 53, the cleaning ring 51 is reset from the second position to the first position. During the reset process of the cleaning ring 51, the cleaning portion 55 cleans the surface of the wire tube 4 to remove impurities attached to the surface of the wire tube 4.

[0074] Furthermore, due to the cooperation between the slide rail 56 and the slider 54 , the first spring 53 is always in a horizontal state during the process of stretching and resetting.

[0075] In order to achieve the separation of the two sets of cleaning rings 51 to a certain distance at the second position, as shown in FIG. Figure 9-11 As shown, a second counterbore 521 is provided on the outer side of the boss 52, a second spring 58 is fixedly installed inside the second counterbore 521, a contact ball 57 is fixedly installed on the second spring 58, and the contact ball 57 can slide inside the second counterbore 521;

[0076] At the same time, two groups of guide slideways 6 are symmetrically arranged on the inner wall of the heating box 21, and the guide slideways 6 are suitable for cooperating with the contact balls 57 to limit the vertical positions of the two groups of cleaning rings 51, and make the two groups of cleaning rings 51 close to each other in the first position, and move away from each other in the second position. Specifically:

[0077] like Fig.11 As shown, the guide slide 6 includes a first slide 61 arranged horizontally, the left end of the first slide 61 corresponds to the first position, and in the initial state, the contact ball 57 is located at the left end of the first slide 61, so that when the cleaning ring 51 moves to the right synchronously with the wire tube 4, the contact ball 57 slides in the first slide 61;

[0078] At the same time, a second slideway 62 inclined upward is provided at the right end of the first slideway 61, and the bottom surface position of the second slideway 62 is lower than the bottom surface position of the first slideway 61, so that the contact ball 57 is suitable for entering the second slideway 62 from the first slideway 61, and cannot return to the first slideway 61 from the second slideway 62, and when the contact ball 57 reaches the right end of the first slideway 61 and enters the second slideway 62, the two groups of cleaning rings 51 will separate from each other, and a first stationary point 63 is provided at the right end of the second slideway 62, and the first stationary point 63 is the separation point of the two groups of cleaning rings 51. When the cleaning ring 51 reaches the separation point, at this time, since only the cleaning portion 55 is in contact with the wire tube 4, the friction force is reduced, and under the action of the first spring 53, the two groups of cleaning rings 51 have a tendency to reset;

[0079] The end of the second slideway 62 is connected to a third slideway 64 inclined upward, and a second stationary point 68 is provided at the highest point of the third slideway 64, so that during the resetting process of the two groups of cleaning rings 51, they can continue to move away from each other to further reduce the friction between the cleaning portion 55 and the wire tube 4, thereby making the two groups of cleaning rings 51 reset smoothly, and the second stationary point 68 corresponds to the second position, so that when the contact ball 57 reaches the second position, the distance between the two groups of cleaning rings 51 reaches a fixed distance, so that the cleaning rings 51 can be reset and cleaned under the action of a smaller friction force;

[0080] In this embodiment, the third slide 64 can also be eliminated, so that the second slide 62 is directly connected to the fourth slide 65, and the second stationary point 68 coincides with the first stationary point 63, so that when the contact ball 57 slides from the starting section of the second slide 62 to the first stationary point 63 (or the second stationary point 68), the two groups of cleaning rings 51 can also be separated.

[0081] Continue to refer Fig.11 A horizontal fourth slideway 65 is provided at the end of the third slideway 64. The fourth slideway 65 is provided so that the two sets of cleaning rings 51 always maintain a fixed distance during the resetting process, so as to better clean the wire tube 4;

[0082] A fifth slideway 66 is provided at the end of the fourth slideway 65, which is inclined downward. The end of the fifth slideway 66 is connected to the first slideway 61, and a slope 67 is provided on the fifth slideway 66. The bottom surface of the slope 67 gradually rises along a position close to the first slideway 61, and a step is formed at the connection between the fifth slideway 66 and the first slideway 61, so that the contact ball 57 is suitable for entering the first slideway 61 from the fifth slideway 66, but cannot enter the fifth slideway 66 from the first slideway 61;

[0083] Therefore, when the contact ball 57 enters the first slideway 61 from the fifth slideway 66, the two groups of cleaning rings 51 are close to each other and in close contact, so as to facilitate the cleaning of the wire tube 4 next time.

[0084] More preferably, the position where the pump body 24 is connected to the heating box 21 is at the bottom of the first position, so that when the two sets of cleaning rings 51 are returned to the initial position after cleaning, impurities will accumulate on the outer wall of the cleaning portion 55 and the wire tube 4. At this time, due to the buffering of the fifth slide 66 and the effect of the airflow, the impurities are sucked into the connecting pipe between the pump body 24 and the heating box 21, thereby preventing impurities from accumulating in the heating box 21.

[0085] like Figure 5-Figure 6 In the embodiment, a tee 31 is provided on the connecting pipe between the pump body 24 and the heating box 21, and a filter screen (not shown in the figure) is provided at the position where the tee 31 is connected to the pump body 24 to prevent impurities from entering the pump body 24;

[0086] At the same time, a collecting component 3 is arranged at the bottom of the tee 31, and the collecting component 3 includes a waste hopper 32 connected to the tee 31, and the waste hopper 32 is used to collect impurities, and a hopper cover 33 is arranged at the bottom of the waste hopper 32, and the hopper cover 33 is used to close the waste hopper 32 to prevent the external cold air flow from being sucked in when the pump body 24 is working, and when the pump body 24 is closed, the hopper cover 33 is opened to clean the waste hopper 32.

[0087] The above description is only the preferred embodiment of the present application and is not intended to limit the present application. For those skilled in the art, the present application may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
