Description

Technical Field

[0001] This application relates to the field of wire marking machines, specifically to an automatic detection structure for the printing plug tube of a wire marking machine. 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 tube clamping mechanism is proposed, including a mounting frame with a wire feeding groove in the middle and a locking groove on the outside of the mounting frame; a clamping component, which includes a conveying pressure roller and a conveying rubber roller, both of which are connected in the wire feeding groove; a swinging component, which includes a tube clamping block and a tube clamping spring, the tube clamping block being connected to the conveying pressure roller through the tube clamping spring; an upper cover, with a locking block at the bottom of the upper cover; the locking block being engaged in the locking groove; and the swinging component being located between the upper cover and the mounting frame.

[0004] The aforementioned technologies have the following drawbacks: the conveying of the wire tube is achieved by rotating the conveying pressure roller and the conveying rubber roller. Since there are corners at the conveying pressure roller and the conveying rubber roller, tube blockage is likely to occur. When tube blockage occurs, it is not discovered until the wire marking machine is completely blocked. At this time, the wire marking tube is severely entangled, making it very troublesome to deal with and affecting production. Utility Model Content

[0005] The purpose of this application is to overcome the above-mentioned technical deficiencies and propose an automatic detection structure for tube blockage in wire marking machines, thereby solving the technical problem that tube blockage is not detected in a timely manner in the prior art.

[0006] To achieve the above technical objectives, the technical solution of this application provides an automatic detection structure for the printing plug tube of a wire marking machine, including a main body mechanism, wherein the main body mechanism includes a middle shell and a channel disposed in the middle shell for accommodating the wire marking tube;

[0007] A printing mechanism, comprising a printhead substrate and a printing roller disposed within a middle shell, the printhead substrate and the printing roller being located on opposite sides of a channel; and,

[0008] The detection mechanism is located inside the middle shell and is situated on one side of the printing roller. The channel passes between the detection mechanism and the printing roller. The detection mechanism is used to detect whether the wire marking tube deviates from the channel.

[0009] In some embodiments, the printing roller is rotatably connected to the main body mechanism, and there is a gap between the middle shell and the cylindrical surface of the printing roller, the gap allowing the printing mechanism to rotate, the gap communicating with a channel.

[0010] In some embodiments, the middle shell is provided with a mounting groove, the detection mechanism is disposed in the mounting groove, and the detection mechanism is located near the gap side.

[0011] In some embodiments, the detection mechanism includes a movable component and a monitoring component, the movable component being rotatably connected within a mounting slot, and the monitoring component being used to monitor the position of the movable component.

[0012] In some embodiments, the movable component includes a swing arm and a retainer, the swing arm being rotatably connected to a mounting groove, and the retainer being disposed on the side of the swing arm near the printing roller.

[0013] In some embodiments, the monitoring component includes a control element and a detector element, the control element being used to control the dwell position of the swing arm, and the detector element being used to detect the dwell position of the swing arm.

[0014] In some embodiments, a pin is fixedly connected inside the middle shell, and the swing arm is sleeved on the pin.

[0015] In some embodiments, the detection assembly includes a slotted sensor disposed within the middle shell, the slotted sensor having a detection slot, and the control assembly is used to position one end of the swing arm near the slotted sensor within the detection slot.

[0016] In some embodiments, the control component includes a torsion spring and a detection plate. The torsion spring is sleeved on a pin, with one end connected to the pin and the other end connected to a swing arm. The detection plate is disposed in a detection groove. The torsion spring causes the end of the swing arm near the groove sensor to abut against the detection plate, thereby placing the end of the swing arm near the groove sensor in the detection groove.

[0017] In some embodiments, the printing roller includes a rotating roller rotatably connected within the middle shell, and a rubber sleeve is fitted over the outer side of the rotating roller.

[0018] In some embodiments, the outer ring of the roller is provided with a plurality of meshing teeth, the outer side of which abuts against the inner side of the rubber sleeve.

[0020] In some embodiments, the swing arm is zigzag-shaped.

[0021] In some embodiments, the swing arm has an inclined surface at one end near the slotted sensor, and the inclined surface abuts against the detection plate.

[0022] Compared with the prior art, the beneficial effects of this application include: the detection mechanism is located inside the middle shell and on one side of the printing roller. This position allows the detection mechanism to detect whether the wire tube is blocked after it passes through the printing area.

[0027] 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.

[0028] This application provides an automatic detection structure for the printing plug tube of a wire marking machine, the structure of which is as follows: Figure 1 - Figure 2 As shown, it includes the main body 1, the printing mechanism 2, and the testing mechanism 3.

[0029] The main structure includes a middle shell 11 and a channel 12 disposed within the middle shell 11, the channel 12 being used to accommodate the wire tube.

[0030] The printing mechanism 2 includes a printhead substrate 21 and a printing roller 22 disposed in the middle shell 11, and the printhead substrate 21 and the printing roller 22 are respectively located on both sides of the channel 12.

[0031] The detection mechanism 3 is located inside the middle shell 11 and is situated on one side of the printing roller 22. The channel 12 passes between the detection mechanism 3 and the printing roller 22. The detection mechanism 3 is used to detect whether the wire marking tube deviates from the channel 12.

[0032] In use, the middle shell 11 serves as the outer casing of the entire wire marking machine, providing support and protection for the various internal mechanisms. The channel 12 provides a clear path for the wire tube, ensuring it passes accurately through the printing area. The printhead substrate 21 and the printing roller 22 are located on opposite sides of the channel 12. As the wire tube moves within the channel 12, the printhead on the printhead substrate 21 performs printing operations on the surface of the wire tube, while the printing roller 22 assists in pressing and propelling the wire tube forward. The detection mechanism 3 is located inside the middle shell 11, to one side of the printing roller 22. This location allows the detection mechanism 3 to promptly detect whether the wire tube is clogged after passing through the printing area. Once cloggedness is detected, the wire marking machine can quickly take measures.

[0033] In this application, the detection mechanism 3 is located inside the middle shell 11 and on one side of the printing roller 22. This position allows the detection mechanism 3 to detect whether the wire tube is blocked after it passes through the printing area. Once the blockage is detected, the wire marking machine can take measures quickly, which enables the operator to respond to the problem quickly and reduce the troubleshooting time.

[0034] To ensure smooth rotation of the printing roller 22, please refer to... Figure 1 In a preferred embodiment, the printing roller 22 is rotatably connected to the main body mechanism 1, and there is a gap 41 between the middle shell 11 and the cylindrical surface of the printing roller 22, the gap 41 allowing the printing mechanism 2 to rotate, and the gap 41 communicating with the channel 12.

[0035] In use, the printing roller 22 is rotatably connected to the main body mechanism 1. This rotatable connection ensures smooth rotation of the printing roller 22 during operation and reduces friction during rotation, minimizing energy loss and component wear, thus providing a stable foundation for subsequent printing operations. A gap 41 is provided between the inner shell 11 and the cylindrical surface of the printing roller 22. This gap 41 is specifically designed to accommodate the rotation of the printing mechanism 2.

[0036] For ease of installation of testing unit 3, please refer to... Figure 1 In a preferred embodiment, the middle shell 11 is provided with an installation groove, and the detection mechanism 3 is disposed in the installation groove, with the detection mechanism 3 located on the side near the gap 41.

[0037] In use, the mounting slot provided inside the middle shell 11 provides a specific installation position and space for the detection mechanism 3, so that the detection mechanism 3 can be accurately and stably placed in the predetermined position.

[0038] To monitor for blockages in the pipeline, please refer to... Figure 1In a preferred embodiment, the detection mechanism 3 includes a movable component and a monitoring component. The movable component is rotatably connected to the mounting slot, and the monitoring component is used to monitor the position of the movable component.

[0039] During use, the movable component is rotatably connected within the mounting slot, allowing it to rotate within a certain range around a specific axis. If a blockage occurs in the pipeline during printing, it will affect the rotatably connected component, causing it to rotate. A monitoring component continuously monitors the positional changes of the movable component and feeds the relevant data back to the control system. The control system uses this data to infer the internal operating status of the printing equipment.

[0040] To monitor for blockages in the pipeline, please refer to... Figure 1 In a preferred embodiment, the movable component includes a swing arm 31 and a retaining wall 32. The swing arm 31 is rotatably connected to the mounting groove, and the retaining wall 32 is disposed on the side of the swing arm 31 near the printing roller 22.

[0041] In use, the swing arm 31 is rotatably connected to the mounting slot, allowing it to rotate flexibly within a certain angle range around the axis of the bearing seat. This rotatable connection enables the swing arm 31 to produce a sensitive rotational response to external forces or environmental changes, thus becoming an important basis for detecting relevant physical quantities or state changes during the printing process. The baffle 32 is located on the side of the swing arm 31 closest to the printing roller 22. During the rotation of the printing roller 22, various physical phenomena or state changes occur, and the baffle 32 can interact with these phenomena and convert them into the rotational motion of the swing arm 31.

[0042] To monitor the position of swing arm 31, please refer to... Figure 1 In a preferred embodiment, the monitoring component includes a control element and a detector element, the control element being used to control the stopping position of the swing arm 31, and the detector element being used to detect the stopping position of the swing arm 31.

[0043] During use, the controller keeps the swing arm 31 in its initial detection or calibration position while the printing equipment is running. As the printing roller 22 rotates and the printing mechanism 2 operates, the swing arm 31 rotates due to various physical forces. The detector continuously monitors the changes in the swing arm 31's position and transmits this position information to the control system.

[0044] To ensure proper rotation of the swing arm 31, please refer to... Figure 2 In a preferred embodiment, a pin 33 is fixedly connected inside the middle shell, and the swing arm 31 is sleeved on the pin 33.

[0045] During use, the pin 33 fixedly connected inside the middle shell provides a stable rotation axis for the swing arm 31, enabling the swing arm 31 to remain stationary when the wire tube passes through normally, and to rotate around the pin 33 when the tube is blocked, thereby triggering the detection and response mechanism to ensure the normal operation of the wire marking machine and the printing quality.

[0046] To detect the stopping position of the swing arm 31, please refer to... Figure 2 In a preferred embodiment, the detection component 5 includes a slotted sensor 51 disposed in the middle shell, the slotted sensor 51 having a detection slot, and the control component 4 is used to position one end of the swing arm 31 near the slotted sensor 51 within the detection slot.

[0047] During operation, when the tubing moves normally within channel 12, the swing arm 31 remains unaffected by the tubing and maintains the position set by control component 4. One end of the swing arm 31 is always located within the detection slot of slot sensor 51. Slot sensor 51 detects that the swing arm 31 is in the normal position and does not emit any abnormal signals. If the tubing becomes blocked or encounters other obstructions within channel 12, the tubing's movement speed will slow down or stop. At this time, the tubing may exert pressure on the retaining wall 32 on the swing arm 31, causing the swing arm 31 to rotate. As the swing arm 31 rotates, the end of the swing arm 31 closest to slot sensor 51 will move out of the detection slot. Slot sensor 51 detects the change in the position of the swing arm 31 and immediately transmits this change signal to the control system of the wire marking machine. After receiving the signal transmitted by slot sensor 51, the control system determines that the tubing is blocked. According to the preset program, the control system can take measures such as stopping printing, issuing an alarm, or attempting to automatically handle the blockage to ensure the normal operation of the wire marking machine and print quality.

[0048] To ensure that the end of the swing arm 31 remains within the detection slot, please refer to... Figure 2 In a preferred embodiment, the control component 4 includes a torsion spring 42 and a detection plate 43. The torsion spring 42 is sleeved on the pin 33, with one end of the torsion spring 42 connected to the pin 33 and the other end of the torsion spring 42 connected to the swing arm 31. The detection plate 43 is disposed in the detection groove. The torsion spring 42 causes one end of the swing arm 31 near the groove-shaped sensor 51 to abut against the detection plate 43, thereby placing the end of the swing arm 31 near the groove-shaped sensor 51 in the detection groove.

[0049] During use, when printing is not in progress or the conduit is passing normally, the torsion spring 42 is in a state of torsion. One end of the torsion spring 42 is connected to the pin 33, and the other end is connected to the swing arm 31. The torque of the torsion spring 42 causes the end of the swing arm 31 near the slotted sensor 51 to abut against the detection plate 43, thus ensuring that this end of the swing arm 31 is located in the detection slot. When the conduit moves normally in the channel 12, since no external force acts on the swing arm 31, the torque of the torsion spring 42 maintains the position of the swing arm 31 unchanged. The swing arm 31 always maintains a state in which one end is located in the detection slot and abuts against the detection plate 43, and the slotted sensor 51 continuously detects that the swing arm 31 is in the normal position and does not emit an abnormal signal. If the conduit is blocked or obstructed in the channel 12, the movement speed of the conduit will slow down or stop. At this time, the conduit may exert pressure on the retaining wall 32 on the swing arm 31. Due to the pressure of the conduit on the retaining wall 32, the swing arm 31 overcomes the torque of the torsion spring 42 and begins to rotate. The end of the swing arm 31 near the slotted sensor 51 gradually moves away from the detection plate 43 and out of the detection slot 511. As the position of the swing arm 31 changes, the slotted sensor 51 detects that the swing arm 31 is no longer in contact with the detection plate 43 and has left the detection slot, and immediately transmits this change signal to the control system of the wire marking machine.

[0050] To ensure proper conduit delivery, please refer to... Figure 2 In a preferred embodiment, the printing roller 22 includes a rotating roller 221 rotatably connected to the inner shell 11, and a rubber sleeve 222 is sleeved on the outer side of the rotating roller 221.

[0051] In use, the rotating roller 221 and the rubber sleeve 222 in the printing roller 22 cooperate with each other. Through the rotation of the rotating roller 221 and the friction of the rubber sleeve 222, the wire tube is pushed and the printing is assisted. This simple and effective printing roller 22 improves the printing efficiency and printing quality of the wire marking machine.

[0052] To ensure a more secure fit between the roller 221 and the rubber sleeve 222, please refer to... Figure 2 In a preferred embodiment, the outer ring of the roller 221 is provided with a plurality of meshing teeth 223, and the outer side of the meshing teeth 223 abuts against the inner side of the rubber sleeve 222.

[0053] During use, the meshing teeth 223 on the outer side of the roller 221 abut against the inner side of the rubber sleeve 222, increasing the friction and connection strength between the roller 221 and the rubber sleeve 222, improving the power transmission efficiency, and preventing the rubber sleeve 222 from slipping. This allows the printing roller 22 to push the tube forward more stably during the printing process, improving the printing efficiency and printing quality of the wire marking machine.

[0054] To ensure smoother conduit passage, please refer to... Figure 2In a preferred embodiment, the retaining wall 32 extends along the outer wall of the rubber sleeve 222.

[0055] When in use, the structural design of the baffle 32 extending along the outer wall of the rubber sleeve 222 allows the baffle 32 to not affect the printing process when the wire tube passes through normally, and to work together with the swing arm 31 to trigger the detection and response mechanism in case of tube blockage, so as to ensure the normal operation of the wire marking machine and the printing quality.

[0056] To make the force distribution on the swing arm 31 more stable, please refer to... Figure 2 In a preferred embodiment, the swing arm 31 is in the shape of a broken line.

[0057] In use, the zigzag design of the swing arm 31 plays a crucial role in the automatic tube plug detection structure of the wire marking machine. It better utilizes space, improves stability, transmits force, and facilitates positional change detection, thereby ensuring that the wire marking machine can promptly detect tube plugging during printing and take appropriate measures to guarantee normal printing operation.

[0058] To increase the contact area between the swing arm 31 and the detection plate 43, please refer to... Figure 2 In a preferred embodiment, the swing arm 31 has an inclined surface 34 at one end near the slotted sensor 51, and the inclined surface 34 abuts against the detection plate 43.

[0059] In use, the swing arm 31 has a bevel 34 at the end near the slotted sensor 51. This design increases the contact stability between the swing arm 31 and the detection plate 43, evenly distributes the torque of the torsion spring 42, and makes it easier for the slotted sensor 51 to detect position changes when tube blockage occurs. After the tube blockage problem is resolved, the bevel 34 also helps the swing arm 31 to accurately reset, ensuring that the automatic detection structure of the wire marking machine can work continuously and stably.

[0060] To better understand this application, the following is combined with... Figure 1 - Figure 2The working principle of the automatic detection structure for plugged wire tubes in a wire marking machine according to this application is described in detail: The inner shell 11 serves as the outer casing of the entire wire marking machine, providing support and protection for the various internal mechanisms. The channel 12 provides a clear path for the wire tube, ensuring that it can accurately pass through the printing area. The printhead substrate 21 and the printing roller 22 are located on opposite sides of the channel 12. When the wire tube moves within the channel 12, the printhead on the printhead substrate 21 can perform printing operations on the surface of the wire tube, while the printing roller 22 assists in pressing the wire tube and propelling it forward. The detection mechanism 3 is located inside the inner shell 11 and on one side of the printing roller 22. This position allows the detection mechanism 3 to promptly detect whether the wire tube is plugged after it passes through the printing area. Once plugging is detected, the wire marking machine can quickly take measures.

[0061] 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.
