Description

[0002] In today's era of rapid development of science and technology, printers have become indispensable equipment in many fields. The cable printing machine is one of them. The cable printing machine can accurately print identification information for various cables, greatly facilitating the installation, management, maintenance, and troubleshooting of the cable workflow.

[0003] The printer is usually composed of a main machine and a cover. When printing, the printed object needs to be installed on the main machine first, such as threading the cable on the main machine, and then closing the cover to print. However, the printed object may deviate from the preset position during printing, affecting the printing effect. For example, when the printer is working, the internal mechanical transmission parts vibrate and cause the main machine to vibrate. The existing cable fixing method (such as the clamping groove fixing method) may not provide enough restraint, causing the cable to jump during printing, thereby destroying the accurate relative position relationship between the print head and the printed object, resulting in blurred, ghosted or misaligned printing content, thereby affecting the printing effect.

[0041] This application provides a printer that can stably fix the workpiece to be printed, preventing it from deviating from a preset position, thereby effectively ensuring the printing effect.

[0042] Specifically, please refer to Figure 1 , Figure 1 This is a schematic diagram of the structure of a printer carrying a workpiece to be printed, provided in an embodiment of this application.

[0043] The printer in this embodiment can be applied to various types, such as wire marking tube printers, label printers, and barcode printers. Correspondingly, the part to be printed, 3, can be in various forms, such as wire marking tubes, various labels, and barcode paper. A wire marking tube printer is a printer used to print markings, such as numbers, letters, and symbols, on wire marking tubes to mark cables. The following description will use a wire marking tube printer as the printer in this embodiment and a wire marking tube as the part to be printed, 3.

[0044] The printer in this embodiment includes a main unit 1, a cover assembly 2, and a pressing assembly 4. The main unit 1, as the core foundation and functional platform of the entire printer, may include a base 11 and a printing assembly and a tube feeding assembly mounted on the base 11. The base 11 has a support portion 100 for carrying the wire marking tubes. The size and shape of the support portion 100 can be determined according to the size and shape of the wire marking tubes, for example, using a groove, slot, or guide rail structure of a specific shape and size. Exemplarily, the support portion 100 is a wire routing groove formed on the base 11. The print head in the printing assembly is the component that prints the marking tube identification information, capable of accurately printing characters, numbers, or symbols on the surface of the wire marking tubes according to preset instructions. The conveyor 12 of the tube feeding assembly is used to transport the wire marking tubes. In this embodiment, the conveyor 12 is a conveyor roller. The wire marking tubes pass through the wire routing groove on the base 11 and pass through the conveyor roller. The conveyor roller, through rotational motion, gradually transports the wire marking tubes to the corresponding position of the print head to ensure smooth printing operations.

[0045] The cover assembly 2 is connected to the host 1 via a movable connection. The movable connection can adopt a hinge, slide rail or other structure, so that the cover assembly 2 can open and close flexibly, which facilitates the installation and removal of the wire tube and the maintenance of the printer.

[0046] In this embodiment, the pressing component 4 is connected to the cover component 2 and is used to press against the wire tube. Exemplarily, the pressing component 4 and the cover component 2 are elastically connected. When the cover component 2 is closed on the main unit 1, the pressing component 4 presses against the wire tube under elastic force. For example, the pressing component 4 includes at least one pressing block and an elastic connecting component. The pressing block, as the part directly in contact with the wire tube, is made of a material with certain hardness and wear resistance, such as engineering plastic or rubber. The elastic connecting component can be a spring (such as a compression spring or tension spring) or an elastic rubber component, etc., with elastic deformation capability. Taking a compression spring as an example, one end of the compression spring is connected to the pressing block. The connection method can be by providing a connecting post or groove on the pressing block, allowing the compression spring to be sleeved at the connection point or snapped into the groove; the other end of the compression spring is connected to the cover component 2, and the cover component 2 has a mounting seat at a corresponding position to ensure that the compression spring is stably installed and can effectively transmit elastic force.

[0047] During printing, components such as the print head and transmission mechanism inside the printer experience vibration and mechanical impact. However, due to the elastic connection between the pressing component 4 and the cover component 2, the pressing component 4 can adaptively adjust the pressing force on the wire tube under the action of elasticity. When vibration or impact is transmitted to the wire tube, the elastic buffer of the compression spring can absorb some of the energy, preventing the wire tube from jumping or displacing due to instantaneous external force. In this way, the printer of this embodiment can always maintain a tight pressing of the pressing block on the wire tube, so that the wire tube is always in a normal working position during the printing process, ensuring that the relative positional accuracy between the print head and the wire tube is within a very small error range. This effectively avoids printing quality problems caused by wire tube jumping, such as clear printed content, no ghosting, and no offset, greatly improving the printing quality of the label.

[0048] Please see Figure 2 and Figure 3 , Figure 2 This is a schematic diagram of the structure of the cover assembly 2 and the pressing assembly 4 provided in the embodiments of this application; Figure 3 This is another structural schematic diagram of the cover component 2 and the pressing component 4 provided in the embodiments of this application.

[0049] In some embodiments, the pressing component 4 includes a first pressing block 41 and a second pressing block 42, both of which are elastically connected to the cover component 2. When the cover component 2 is closed on the host 1, the first pressing block 41 and the second pressing block 42 work together to fix the wire tube. Specifically, the first pressing block 41 and the second pressing block 42 are spaced apart along the conveying direction of the workpiece 3 to be printed, that is, the first pressing block 41 and the second pressing block 42 are spaced apart along the direction of the wire groove. The spacing distance can be determined according to the length and diameter of the wire tube. For example, for a longer wire tube, the spacing distance can be appropriately increased to provide stable pressing at different positions; for a wire tube with a larger diameter or a harder material, the spacing distance can be appropriately decreased to enhance the fixing effect.

[0050] When the cover assembly 2 is in the closed state, at least one of the first pressing block 41 and the second pressing block 42 presses against the wire tube. In some cases, the first pressing block 41 may press against the wire tube alone, for example, when the wire tube is thin, the first pressing block 41, under the action of elasticity, presses the wire tube tightly and fixes it in the cable tray. In other cases, the first pressing block 41 and the second pressing block 42 may press against the wire tube simultaneously, for example, for a thicker wire tube, the first pressing block 41 and the second pressing block 42, under the action of their respective elasticity, apply pressure to the wire tube from different positions, making it more firmly fixed in the cable tray.

[0051] Furthermore, in the conveying direction of the printable part 3, there is a first gap between the first pressure block 41 and the conveyor 12. That is, the first pressure block 41 is located between the conveyor roller and the entrance of the wire guide in the extension direction of the wire guide. After the wire tube enters from the entrance of the wire guide, it first passes through the area where the first pressure block 41 is located, and then enters the conveyor roller. The distance between the first pressure block 41 and the conveyor roller is the first gap, which is set to be no less than 1 cm and no more than 7 cm. This distance range is an optimized value obtained through a large number of experiments and practical applications. For example, when the first gap is 4 cm, in actual operation, after the wire tube enters from the entrance of the wire guide, it will be constrained by the first pressure block 41 4 cm away from the conveyor roller. In this way, when the wire tube is about to be conveyed to the conveyor roller, the presence of the first pressure block 41 can restrict and buffer it to a certain extent, preventing the wire tube from jumping due to the sudden traction force of the conveyor roller when it is conveyed to the conveyor roller.

[0052] The first pressing block 41 is rotatably connected to the cover assembly 2, for example, via a hinge structure. Furthermore, the first pressing block 41 is inclined in the direction of pressing against the workpiece 3 to be printed, with its lower end positioned closer to the conveyor 12. For example, as the first pressing block gradually moves downwards towards and presses against the wire tube, due to the inclination angle of the first pressing block 41, the wire tube will gradually push the first pressing block 41 upwards along the inclined surface, causing the first pressing block 41 to rotate.

[0053] A first elastic element 44 is provided between the first pressure block 41 and the cover assembly 2. The first elastic element 44 includes either a torsion spring or an elastic rubber component. In this embodiment, the first elastic element 44 is a torsion spring. One end of the first elastic element 44 is connected to the first pressure block 41, and the other end is connected to the cover assembly 2. When the wire tube pushes the first pressure block 41 to rotate, the first elastic element 44 will be twisted and store elastic potential energy. For example, during normal printing, the force exerted by the wire tube on the first pressure block 41 will cause the first elastic element 44 to twist to a suitable angle. The resulting elastic force will react on the first pressure block 41, making it press tightly against the wire tube. It can also adaptively adjust according to the slight deformation or positional change of the wire tube, always maintaining a stable fixation on the wire tube.

[0054] Furthermore, in the conveying direction of the printable part 3, there is a second gap between the second pressure block 42 and the conveyor 12, which is greater than the first gap. That is, in the direction of the extension of the wiring trough, the second pressure block 42 is located between the first pressure block 41 and the entrance of the wiring trough. After entering the printer, the wire tube will first pass through the second pressure block 42 and then through the first pressure block 41. The main function of the second pressure block 42 is to pre-compress the wire tube fed into the printer. When the wire tube first enters the printer, its state may be relatively loose. The second pressure block 42 can apply a certain pressure to the wire tube before it is conveyed to the first pressure block 41, so that the wire tube is initially stabilized. For example, for some wire tubes with softer texture, they may be easily bent or deformed when entering. The pre-compression effect of the second pressure block 42 can keep them in a relatively straight state so that a better clamping effect can be achieved when they reach the first pressure block 41.

[0055] The second pressure block 42 can slide relative to the cover assembly 2 to effectively pre-press the wire marking tube. For example, the cover assembly 2 has a groove for accommodating the second pressure block 42, which can move vertically within the groove. The second pressure block 42 is vertically positioned in the direction of pressing the wire marking tube, thus vertically pressing the workpiece 3 to be printed, which helps to apply stable pressure to the wire marking tube in the vertical direction.

[0056] A second elastic element 45 is provided between the second pressing block 42 and the cover assembly 2. The second elastic element 45 includes either a compression spring or an elastic rubber component; in this embodiment, the second elastic element 45 is a compression spring. One end of the second elastic element 45 is connected to the second pressing block 42, and the other end is connected to the cover assembly 2. For example, the second elastic element 45 is pressed against the groove, with one end of the second elastic element 45 abutting against the inner wall of the groove and the other end abutting against the second pressing block 42.

[0057] When the cover assembly 2 is closed, the second pressure block 42 presses against the wire tube under the elastic force of the second elastic member 45. As the size or position of the wire tube changes, the second elastic member 45 will expand and contract accordingly to adjust the pressure of the second pressure block 42. For example, for wire tubes of different diameters, the second elastic member 45 can automatically adjust the compression amount according to its elastic characteristics, so that the second pressure block 42 applies appropriate pressure to achieve effective pre-compression of the wire tube.

[0058] Furthermore, in this embodiment, the first pressure block 41 and the second pressure block 42 can work together to press against wire tubes of different diameters.

[0059] Specifically, in the vertical direction, the end of the first pressure block 41 is lower than the end of the second pressure block 42. When pressing against a small-diameter wire tube, the first pressure block 41, under the action of the first elastic element 44, can adaptively adjust according to the actual size and shape of the wire tube, closely fitting the surface of the wire tube and applying appropriate pressure. A first pressure roller 43 is provided at the end of the first pressure block 41. The first pressure roller 43 is cylindrical, and its material has good wear resistance and appropriate hardness. It typically adopts a structure where a metal core is covered with rubber or plastic. Under external force, for example, when the wire tube contacts the first pressure roller 43 during conveying and generates friction, the first pressure roller 43 can rotate around its axis. In this way, the sliding friction between the wire tube and the first pressure block 41 is converted into rolling friction, greatly reducing the friction force. This allows the wire tube to move smoothly under the first pressure block 41, effectively avoiding the problem of wire tube conveying jams caused by excessive friction, making the wire tube conveying smoother.

[0060] The second pressure block 42 is vertically positioned so that its end is higher than the end of the first pressure block 41. When pressing against a large-diameter wire tube, the larger diameter of the wire tube will first contact the lower end of the first pressure block 41. Under the action of the first elastic element 44, the first pressure block 41 adjusts its position according to the specific situation of the large-diameter wire tube and applies a small pressure to initially fix the large-diameter wire tube. At this time, the second pressure block 42, under the action of the second elastic element 45, contacts the large-diameter wire tube and applies a larger pressure. The first pressure block 41 and the second pressure block 42 work together to stably press against the large-diameter wire tube from different positions, ensuring that the large-diameter wire tube will not shift or jump during the printing process. The end of the second pressure block 42 is also provided with a first pressure roller 43, whose working principle is the same as that of the first pressure roller 43 on the first pressure block 41.

[0061] In this embodiment, the pressure assembly 4 can automatically adjust the fixing method according to the diameter of the wire tube. When printing small-diameter wire tubes, since the end of the first pressure block 41 is lower, it will preferentially contact the wire tube and achieve adaptive fixing under the action of the first elastic member 44, providing appropriate pressure for the small-diameter wire tube and avoiding damage to the wire tube due to excessive pressure. This ensures the stability of the small-diameter wire tube during the printing process, thereby guaranteeing print quality. For large-diameter wire tubes, they first contact the first pressure block 41 with a lower end and are initially fixed with a smaller pressure. Subsequently, the second pressure block 42 also participates in the cooperative fixing and applies a larger pressure. The above-mentioned dual fixing mechanism can effectively fix the large-diameter wire tube, keeping it in a precise position during the printing process and avoiding displacement or jumping, thereby guaranteeing print quality.

[0062] Please see Figure 1 and Figure 4 , Figure 4 This is a schematic diagram of the printer provided in an embodiment of this application.

[0063] To further improve the pressure effect on the wire tube, this embodiment also includes a cover assembly 222. Specifically, the cover assembly 2 includes a first movable cover 21 and a second movable cover 22. The first movable cover 21 is located between the base 11 and the second movable cover 22, and is connected to the base 11 by a rotatable connection. Exemplarily, the first movable cover 21 includes a first cover body 211 and a rotating arm 212. One end of the first cover body 211 is connected to the rotating arm 212, and the rotating arm 212 is rotatably connected to the base 11. The rotatable connection adopts a suitable pin or hinge structure to ensure the stability and flexibility of the first movable cover 21 during the opening and closing process. The other end of the first cover body is connected to the pressure assembly 4. When the first movable cover 21 is rotated to close, the pressure assembly 4 can vertically press the wire tube from above, so that the wire tube is stably placed in the wiring groove of the base 11.

[0064] The second movable cover 22 includes a second cover body 221 and a cover assembly 222. The second cover body 221 is rotatably connected to the base 11. The rotatable connection adopts a suitable pin or hinge structure to ensure the stability and flexibility of the second movable cover 22 during the opening and closing process, so as to facilitate the operation of the operator and the maintenance of the printer's internal parts.

[0065] The cap assembly 222 is connected to the side of the second cover 221 facing the first movable cover 21. When the cover assembly 2 is fully closed, the cap assembly 222 will apply additional pressure to the first movable cover 21, so that the pressing assembly 4 on the first movable cover 21 presses the wire tube more tightly.

[0066] Furthermore, the cap assembly 222 includes at least one second pressure roller 2221 for pressing against the first movable cap 21. The second pressure roller 2221 is made of a material with good wear resistance and appropriate hardness, such as rubber or plastic, so that the second pressure roller 2221 undergoes slight deformation when in contact with the first movable cap 21, thus making the pressure applied by the second pressure roller 2221 to the first movable cap 21 more uniform. When two second pressure rollers 2221 are provided, the two second pressure rollers 2221 are spaced apart. The spaced arrangement allows the first movable cap 21 to be subjected to more uniform force when under pressure, avoiding problems such as deformation of the first movable cap 21 or insecure fixing of the wire tube due to excessive or insufficient local pressure. For example, the two second pressure rollers 2221 are located at both ends or key stress points of the first movable cover 21. When the second movable cover 22 is closed, the two second pressure rollers 2221 simultaneously apply pressure to the first movable cover 21, so that the pressure-receiving component 4 on the first movable cover 21 can evenly transmit the pressure to the wire tube, ensuring that the wire tube can be tightly fixed in the entire length direction, thereby ensuring good printing quality.

[0067] like Figure 2 As shown, in some embodiments, the first movable cover 21 has a through hole 2111 through which a portion of the second pressing block 42 can pass. The position of the through hole 2111 is determined according to the movement trajectory of the second pressing block 42 during the closing process of the second movable cover 22, ensuring that the second pressing block 42 can accurately pass through the through hole 2111 when the cover is closed. The shape of the through hole 2111 is adapted to the outer contour of the portion of the second pressing block 42 that protrudes through it, for example, it can be circular, rectangular or other shapes, ensuring that the second pressing block 42 can pass through smoothly.

[0068] When the cover assembly 2 is in the closed state, there is a third gap between the first movable cover 21 and the second movable cover 22. The third gap is specifically used to avoid the portion of the second pressing block 42 that protrudes through the through hole 2111. Due to the existence of the third gap, the portion of the second pressing block 42 that protrudes through the through hole 2111 will not come into contact with or collide with the first movable cover 21, thus avoiding affecting the closed state of the first movable cover 21, ensuring a stable printing environment, and thereby ensuring print quality.

[0069] The above are merely preferred embodiments of this application and are not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
