Technical Field

[0001] This application relates to the field of wire marking machines, specifically to a wire marking machine printing anti-clogging tube structure. Background Technology

[0002] A wire marking printer, also known as a wire marking machine or wire labeling machine, is a specialized device for marking secondary wires in electrical control and distribution equipment. It utilizes thermal transfer printing technology, achieving a printing resolution of up to 300 dpi. It can print characters on materials such as PVC tubing, heat shrink tubing, and self-adhesive labels. Commonly used for marking secondary wires in electrical control and distribution equipment, it meets the needs of power plants, electrical equipment factories, substations, and the power industry for wire identification and marking.

[0003] In related technologies, a wire marking machine for conduits has been proposed, comprising a wire marking machine body, a connecting cylinder provided at the feed inlet position on the side wall of the wire marking machine body, a circular hole provided on the side of the connecting cylinder near the wire marking machine body, the circular hole being aligned with the feed inlet of the wire marking machine body, a square hole provided at the end of the connecting cylinder away from the circular hole, an electric heating element for heating the conduit being provided inside the square hole of the connecting cylinder, and a drive mechanism for rotating the connecting cylinder being provided on the side wall of the wire marking machine body.

[0004] The aforementioned technologies have the following drawbacks: when the conduit is fed into the wire marking machine, there is sliding friction between the conduit and the inner wall of the connecting cylinder, and between the conduit and the inner wall of the circular hole of the wire marking machine. The friction force is relatively large, which not only easily damages the conduit, but also may cause blockage or clogging during the inlet and outlet of the conduit, affecting printing.

[0026] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0027] This application provides a structure for preventing clogging during wire marking machine printing, the structure of which is as follows: Figure 1 - Figure 5 As shown, it includes the main body mechanism 1, the inlet guide mechanism 2, and the outlet guide mechanism 3.

[0028] The main body 1 includes a middle shell 11, on which a wire tube groove 12 is formed.

[0029] The inlet guide mechanism 2 includes an inlet roller 21 located at the inlet of the conduit groove 12, which abuts against the side wall of the conduit.

[0030] The tube guide mechanism 3 includes a tube outlet roller 31 located at the outlet of the tube groove 12, which abuts against the side wall of the tube.

[0031] In use, the middle shell 11, as the main part of the wire marking machine, contains key components such as the printing mechanism and control circuit. It provides support and a mounting base for the entire anti-clogging tube structure. The inlet roller 21 is located at the inlet of the wire tube groove 12. When the wire tube is inserted into the wire marking machine from the outside, it first passes through the inlet roller 21. The inlet roller 21 abuts against the side wall of the wire tube. As the wire tube moves forward, friction is generated between the wire tube and the inlet roller 21, causing the inlet roller 21 to rotate. The rotation of the inlet roller 21 guides the wire tube smoothly into the wire marking machine, ensuring the accurate positioning of the wire tube and preventing the wire tube from bending, twisting, or deviating from the correct path at the inlet. At the same time, the abutment of the inlet roller 21 can also apply a certain pressure to the wire tube, keeping the wire tube in a stable forward direction. The outlet roller 31 is located at the outlet of the middle shell 11. After the wire tube has been printed by the printing mechanism, it leaves the wire marking machine from the outlet roller 31. The outlet roller 31 abuts against the side wall of the wire tube. Similarly, as the conduit moves, friction is generated between it and the outlet roller 31, causing the outlet roller 31 to rotate. The rotation of the outlet roller 31 guides the conduit smoothly away from the marking machine, preventing the conduit from becoming clogged or tangled at the outlet. The contact between the outlet roller 31 and the conduit also helps maintain the tension of the conduit, ensuring that the conduit remains neat after leaving the marking machine.

[0032] In this application, the inlet roller 21 ensures that the wire tube can accurately enter the printing mechanism when entering the wire marking machine, avoiding the wire tube from being blocked at the inlet due to bending, twisting or inaccurate positioning. The outlet roller 31 guides the wire tube to leave the wire marking machine smoothly, preventing the wire tube from accumulating or tangling at the outlet, thereby reducing the risk of blockage. Through the synergistic effect of the inlet guide mechanism 2 and the outlet guide mechanism 3, the blockage of the wire tube during the printing process is effectively prevented, improving the printing efficiency and stability of the wire marking machine.

[0033] To ensure smoother conduit exit, please refer to... Figure 2 In a preferred embodiment, the tube guide mechanism 3 further includes a tube floating pressure block 32 disposed at the outlet of the conduit groove 12. The tube floating pressure block 32 is used to abut against the side wall of the conduit. The conduit groove 12 is provided with a fixing component 33 for fixing the tube floating pressure block 32.

[0034] During use, as the tubing approaches the outlet of the tubing groove 12, adjust the position of the tube-exit floating pressure block 32 so that it abuts against the side wall of the tubing. The function of the tube-exit floating pressure block 32 is to increase the pressure on the tubing, further stabilizing its position. During printing, the tubing may be affected by various external forces, causing it to wobble. By abutting against the tubing, the tube-exit floating pressure block 32 can reduce the amplitude of the wobble, ensuring that the tubing remains in the correct position so that the printed content can be accurately printed onto the tubing. Because the tube-exit floating pressure block 32 has a certain degree of elasticity and adjustability, it can adapt to tubing of different diameters. Regardless of the size of the tubing, the tube-exit floating pressure block 32 can provide stable support by adjusting its position and pressure to maintain close contact with the tubing. The function of the fixing component 33 is to ensure that the tube-exit floating pressure block 32 always maintains pressure on the tubing, thereby maintaining the stability of the tubing throughout the printing process. Even if the tubing is affected by the tension of the printing mechanism or other external forces, the tube-exit floating pressure block 32 can maintain stable support for the tubing through the fixing action of the fixing component 33.

[0035] To secure the outlet floating pressure block 32, please refer to... Figure 3 In a preferred embodiment, the fixing component 33 includes a bolt 331 threaded onto the conduit groove 12, and the outlet floating pressure block 32 is provided with a through hole 332 for the bolt 331 to pass through.

[0036] During use, after the outlet tube floating pressure block 32 is adjusted to the appropriate position, the bolt 331 is passed through the through hole 332 on the outlet tube floating pressure block 32, and the bolt 331 is rotated. Since the bolt 331 is threadedly connected to the tube groove 12, as the bolt 331 rotates, it gradually screws into the tube groove 12, and the head of the bolt 331 gradually approaches the outlet tube floating pressure block 32. As the bolt 331 continues to screw in, the head of the bolt 331 applies pressure to the outlet tube floating pressure block 32. This pressure causes the outlet tube floating pressure block 32 to press tightly against the side wall of the tube, thereby fixing the position of the outlet tube floating pressure block 32. During the printing process, the tube may be affected by external forces such as tension and vibration from the printing mechanism. However, since the outlet tube floating pressure block 32 is fixed in its current position by the bolt 331, it can continuously provide stable pressure to the tube, preventing the tube from shaking, shifting, or becoming blocked at the outlet.

[0037] If it is necessary to adjust the position of the tubing or replace it with a different size tubing, the bolt 331 can be rotated in the opposite direction, gradually moving the head of the bolt 331 away from the tube outlet floating pressure block 32. As the bolt 331 is unscrewed, the pressure of the bolt 331 on the tube outlet floating pressure block 32 gradually decreases until the tube outlet floating pressure block 32 can move freely again. At this point, the position of the tube outlet floating pressure block 32 can be readjusted, and then the bolt 331 can be reinserted and rotated to fix it. This adjustability allows the fixing component 33 to adapt to different printing needs and tubing changes.

[0038] To further improve the stability of the outlet floating pressure block 32, please refer to... Figure 3 In a preferred embodiment, a washer 34 is fitted onto the bolt 331, and the washer 34 is used to abut against the conduit groove 12.

[0039] During use, the washer 34 fitted on the bolt 331 increases the contact area, disperses pressure, and provides a buffering effect during the process of fixing the floating pressure block 32 of the outlet pipe, thereby improving the stability and reliability of the connection between the bolt 331 and the conduit groove 12, and ensuring that the anti-clogging pipe structure of the wire marking machine can work stably during use.

[0040] To ensure a tighter fit between the outlet floating pressure block 32 and the conduit, please refer to... Figure 3 In a preferred embodiment, a spring 35 is provided between the outlet floating pressure block 32 and the conduit groove 12. One end of the spring 35 is connected to the side of the outlet floating pressure block 32 away from the bolt 331, and the other end of the spring 35 is connected to the conduit groove 12. The spring 35 is in a compressed state, and the spring 35 causes the outlet floating pressure block 32 to tend to move in the direction of the pipeline.

[0041] During use, spring 35 remains compressed throughout the printing process, continuously providing pressure to the tube ejection floating block 32 towards the tube. Even when the tube is affected by external forces such as tension or vibration from the printing mechanism, the pressure of spring 35 ensures that the tube ejection floating block 32 remains in close contact with the tube, preventing the tube from wobbling, shifting, or clogging at the outlet. If the tube diameter changes slightly during printing due to temperature variations or material deformation, the elasticity of spring 35 allows the tube ejection floating block 32 to automatically adjust to accommodate the changes. The compression and extension of spring 35 can compensate for changes in tube size within a certain range, maintaining stable pressure on the tube. In summary, spring 35 between the tube ejection floating block 32 and the tube groove 12 plays a crucial role in the anti-clogging tube structure of the entire wire marking machine. By providing continuous pressure and adaptive adjustment capabilities, it ensures that the tube ejection floating block 32 remains in close contact with the tube, improving the stability of the tube at the outlet, preventing clogging and wobbling, and also providing convenience for adjustment and unlocking operations.

[0042] To ensure a more secure fixation of the outlet roller 31, please refer to... Figure 5 In a preferred embodiment, a roller plate 36 is provided at the outlet of the conduit trough 12, and the outlet roller 31 is fixed on the roller plate 36.

[0043] During use, the roller plate 36 provides a solid mounting base for the tube output roller 31. It ensures that the tube output roller 31 remains in the correct position throughout the printing process, preventing displacement or wobbling due to tube movement or external forces. The design of the roller plate 36 also facilitates maintenance if the tube output roller 31 malfunctions or needs replacement. The tube output roller 31 can be directly disassembled and installed on the roller plate 36 without requiring extensive adjustments to the entire wire marking machine structure.

[0044] To prevent foreign objects from entering the wire marking machine, please refer to... Figure 4 In a preferred embodiment, the outlet of the conduit groove 12 is provided with a blocking component 4 for preventing foreign objects from entering the middle shell 11.

[0045] During use, the blocking component 4 at the outlet of the middle shell 11 effectively prevents foreign objects from entering the wire marking machine through physical blocking, size adaptation and positional advantages, protecting the printing mechanism and other key components, and improving the reliability and service life of the wire marking machine.

[0046] To prevent foreign objects from entering the wire marking machine, please refer to... Figure 5In a preferred embodiment, the blocking assembly 4 includes a stop block 41 rotatably connected to the outlet of the conduit groove 12. A torsion spring 42 is provided between the stop block 41 and the conduit groove 12. One end of the torsion spring 42 is connected to the stop block 41, and the other end of the torsion spring 42 is connected to the conduit groove 12. The torsion spring 42 causes the stop block 41 to rotate in the direction of the outlet roller 31, so that the end of the stop block 41 abuts against the outlet roller 31.

[0047] In use, when printing is required, the filament is introduced into the main body mechanism 1 of the wire marking machine through the inlet guide mechanism 2. After passing through the printing area, the filament moves towards the outlet of the middle shell 11. When the filament approaches the outlet, it contacts the stop block 41. Due to the thrust of the filament, the stop block 41 overcomes the torque of the torsion spring 42 and begins to rotate away from the outlet roller 31. The filament continues to move forward, pushing the stop block 41 to open further. The filament passes through the gap between the stop block 41 and the outlet roller 31, smoothly leaving the wire marking machine. Throughout the printing process, the torsion spring 42 always applies a torque towards the outlet roller 31 to the stop block 41. This torque causes the stop block 41 to always tend to return to the closed state when there is no thrust from the filament. After the filament passes, if an external foreign object approaches the outlet of the middle shell 11, the torque of the torsion spring 42 will cause the stop block 41 to close quickly, preventing the foreign object from entering. Since the end of the stop 41 abuts against the outlet roller 31, a relatively enclosed space can be formed, effectively preventing dust, debris and other foreign objects from entering the wire marking machine.

[0048] To reduce wear on stop 41, please refer to... Figure 4 In a preferred embodiment, a stop wheel is rotatably connected to the end of the stop block 41, and the stop wheel is used to abut against the outlet roller 31.

[0049] In use, when printing is required, the tube is introduced into the main body mechanism 1 of the wire marking machine from the tube inlet guide mechanism 2. After passing through the printing area, the tube moves towards the outlet of the middle shell 11. When the tube approaches the outlet, it first contacts the stop roller. Due to the thrust of the tube, the stop block 41 overcomes the torque of the torsion spring 42 and begins to rotate away from the tube outlet roller 31. At the same time, the stop roller also rotates with the stop block 41, reducing the friction between the tube and the stop block 41, making it easier for the tube to push the stop block 41 open. In summary, the stop roller, which is rotatably connected to the end of the stop block 41, plays a role in reducing friction, ensuring smooth opening and closing, and enhancing the blocking effect in the anti-clogging tube structure of this wire marking machine. It works in conjunction with the stop block 41 and the torsion spring 42 to improve the reliability and service life of the wire marking machine.

[0050] To reduce the likelihood of slipping, please refer to Figure 5 In a preferred embodiment, the outer sides of the inlet roller 21, the outlet roller 31, and the stop roller are all provided with an anti-slip layer.

[0051] During use, the inlet roller 21, the outlet roller 31, and the anti-slip layer on the outside of the guide roller play an important role in increasing friction during the insertion, output, and blocking of foreign objects of the tube, thereby improving the stability and reliability of the anti-clogging tube structure of the wire marking machine.

[0052] To better understand this application, the following is combined with... Figure 1 - Figure 5 The working principle of the anti-clogging tube structure for a wire marking machine, as described in this application, is explained in detail: The middle shell 11, as the main part of the wire marking machine, includes key components such as the printing mechanism and control circuit. It provides support and a mounting foundation for the entire anti-clogging tube structure. The inlet roller 21 is located at the inlet of the wire tube groove 12. When the wire tube is inserted into the wire marking machine from the outside, it first passes through the inlet roller 21. The inlet roller 21 abuts against the side wall of the wire tube. As the wire tube moves forward, friction is generated between the wire tube and the inlet roller 21, causing the inlet roller 21 to rotate. The rotation of the inlet roller 21 guides the wire tube smoothly into the wire marking machine, ensuring the accurate positioning of the wire tube and preventing the wire tube from bending, twisting, or deviating from the correct path at the inlet. At the same time, the abutment of the inlet roller 21 can also apply a certain pressure to the wire tube, keeping the wire tube in a stable forward direction. The outlet of the middle shell 11 is located at the outlet of the middle shell 11. After the wire tube has been printed by the printing mechanism, it leaves the wire marking machine from the outlet roller 31. The tube exit roller 31 abuts against the side wall of the tube. Similarly, as the tube moves, friction is generated between it and the exit roller 31, causing the exit roller 31 to rotate. This rotation guides the tube smoothly away from the marking machine, preventing blockage or tangling at the outlet. The contact between the exit roller 31 and the tube also helps maintain the tube's tension, ensuring the tube remains neat after leaving the marking machine.

[0053] The specific embodiments described above do not constitute a limitation on the scope of protection of this application. Any other corresponding changes and modifications made based on the technical concept of this application should be included within the scope of protection of the claims of this application.
