[0069] A wire marking printer, also known as a wire marking machine, can print characters on wire tubes such as sleeves and heat shrink tubing for marking wiring in electrical control and power distribution equipment.

[0070] In related technologies, after the characters are printed, a wire marking printer is needed to cut the wire marking tube. When using a wire marking printer, there is a risk that the user may be cut by the printer's cutting device.

[0071] To address the aforementioned technical problems, this application provides a line marking printer. The line marking printer provided in this application will now be described in detail with reference to the accompanying drawings.

[0072] Please refer to Figure 1 This application discloses a wire marking printer 1, comprising a base 100, a cover 200, a cutting device 300, a cover opening detection device (not shown in the figure), and a controller (not shown in the figure). The base 100 has a wire routing channel 110. The cutting device 300 is disposed in the wire routing channel 110 and is used to cut the wire marking tubes 2 within the wire routing channel 110. The cover 200 is movably disposed on the base 100, capable of exposing and covering the wire routing channel 110 and the cutting device 300. The cover opening detection device is disposed on the base 100 and is used to detect whether the cover 200 is open, thus exposing the wire routing channel 110 and the cutting device 300. The controller is electrically connected to the cutting device 300 and the cover opening detection device, and is used to control the cutting device 300 to stop operating when the cover 200 is detected to be open.

[0073] The base 100 serves as the main structure of the wire marking printer 1, providing a mounting base for the cover 200, cutting device 300, cover opening detection device, and controller. The base 100 also features a wiring channel 110. The wiring channel 110 is the path that allows the wire marking tube 2 to pass through. The wire marking tube 2 is located within the wiring channel 110 and can move along it. (See [reference]). Figure 1 The wire marking tube 2 can move from right to left along the wiring channel 110 in the direction of the arrow. When the wire marking printer 1 prints characters on the wire marking tube 2, the wire marking tube 2 can move freely in the wiring channel 110. At this time, the cutting device 300 does not cut the wire marking tube 2. After the characters are printed, the cutting device 300 cuts the wire marking tube 2.

[0074] The cover 200 covers the surface of the base 100, protecting the base 100, its wiring channel 110, and the cutting device 300, preventing dust, particles, and other foreign objects from entering the wire marking printer 1 and affecting its normal operation. The cover 200 can be installed on the base 100 by rotation or sliding. When maintaining, repairing, or replacing the wire marking tube 2, the cover 200 can be opened to expose the wiring channel 110 and the cutting device 300 on the base 100. Under normal operating conditions, the cover 200 is closed, sealing the wiring channel 110 and the cutting device 300.

[0075] The cover opening detection device is used to detect whether the cover 200 exposes the wiring channel 110 and the cutting device 300. The cover opening detection device can use a distance sensor, limit switch, etc.

[0076] When a distance sensor is used in the cover opening detection device, the openness of the cover 200 can be determined based on the distance between the base 100 and the cover 200. For example, when the distance between the base 100 and the cover 200 is less than a preset threshold, such as less than or equal to 10mm, the cover 200 is determined to be open. When the distance between the base 100 and the cover 200 is less than the preset threshold, such as greater than or equal to 50mm, the cover 200 is determined to be closed. Distance sensors come in various types and can be categorized based on their different distance measurement principles. Examples include ultrasonic sensors, laser sensors, infrared sensors, photoelectric distance sensors, and inductive distance sensors. An ultrasonic sensor includes a transmitter and a receiver. The transmitter emits ultrasonic pulses, and the receiver receives the ultrasonic waves reflected by an object and calculates the distance between the object and the sensor. A laser sensor uses a laser beam to measure the distance between an object and the sensor, calculating the distance by emitting a laser beam and measuring the reflection time from the sensor to the object. Infrared sensors measure distance by measuring the infrared light reflected from an object; they emit infrared light and receive the reflected light to calculate the distance. Photoelectric distance sensors use a laser to emit a laser beam and calculate the distance to the sensor by measuring the time difference between the laser beam's reflection and its return.

[0077] When a limit switch is used in the lid opening detection device, the limit switch body can be installed on one of the base 100 and the lid 200, and a trigger structure can be installed on the other. When the lid 200 is closed or opened, the trigger structure can drive the limit switch body to move. After the limit switch body moves, it generates a switch signal, which can be used to determine whether the lid 200 is open. There are various ways to set the limit switch, and designers can set it flexibly. This application does not make a specific limitation on it.

[0078] The controller is electrically connected to the cutting device 300 and the cover-opening detection device, and is used to control the cutting device 300 to stop cutting when the cover-opening detection device detects that the cover 200 exposes the wiring channel 110 and the cutting device 300. The controller can be a processing chip on the internal circuit board of the wire marking printer 1, or it can be a dedicated control module. Designers can set a suitable controller by considering factors such as the internal space of the wire marking printer 1 and the cost of the equipment; this application does not impose specific limitations on this.

[0079] The solution provided in this application electrically connects the controller to the cutting device 300 and the cover-opening detection device. The cover-opening detection device can detect whether the cover 200 exposes the wiring channel 110 of the base 100 and the cutting device 300. When the cover-opening detection device detects that the cover 200 is open and exposes the wiring channel 110 of the base 100 and the cutting device 300, the controller can promptly control the cutting device 300 to stop cutting. Therefore, when using the wire marking printer 1 provided in this application, users can effectively avoid being cut by the cutting device 300 of the wire marking printer 1.

[0080] See Figure 1 , Figure 2 and Figure 3 In some embodiments, the wiring channel 110 includes a first segment 111 and a second segment 112 connected to each other; the first segment 111 and the second segment 112 are located on both sides of the cutting device 300; the second segment 112 has an outlet end 1120, and the distance d1 between the outlet end 1120 and the cutting device 300 is greater than or equal to 80mm. For example, it can be 80mm, 85mm, 90mm, 95mm, 100mm, etc. It is understood that, considering the layout of components such as the cutting device 300 in the wire marking printer 1, the distance between the outlet end 1120 and the cutting device 300 cannot be increased indefinitely. Designers can determine a suitable distance between the outlet end 1120 and the cutting device 300 based on factors such as the overall size of the wire marking printer 1 and the position of the cutting device 300 in the wiring channel 110. In this embodiment of the application, by setting the outlet end 1120 at a greater distance from the cutting device 300, the user's finger cannot reach the cutting device 300 when it extends from the outlet end 1120 to the cutting device 300, thereby further reducing the risk of the finger being cut by the cutting device 300.

[0081] See Figure 1 and Figure 2In some embodiments, the extension path of the second segment 112 is tortuous. In other words, the second segment 112 extends in a curved manner rather than in a straight line. Thus, when a user's finger, a stick, or other straight object is inserted into the second segment 112, it will be blocked by the curved structure within the second segment 112. This reduces the risk of the finger being cut by the cutting device 300 and also prevents straight objects like sticks from damaging the cutting device 300.

[0082] See Figures 1 to 3 To further reduce the risk of being cut by the cutting device 300, in some embodiments, the line number printer 1 may also include a protective mechanism 400, which is rotatably connected to the base 100 and partially located in the second section 112. The protective mechanism 400 has an extreme position to prevent foreign objects from entering the second section 112.

[0083] Understandably, see Figure 1 and Figure 2 The wire tube 2 moves from the right side to the left side of the cutting device 300 along the wire routing channel 110, that is, the first section 111 of the wire routing channel 110 moves to the second section 112, and finally exits from the outlet end 1120 of the second section 112. In this embodiment, a protective mechanism 400 is provided in the second section 112, and the protective mechanism 400 can only move to the limit position in the opposite direction of the movement of the wire tube 2, to prevent foreign objects from entering the second section 112, thereby preventing the user's fingers from contacting the cutting device 300, effectively reducing the risk of being cut by the cutting device 300.

[0084] See Figure 3 and Figure 4 In some embodiments, the second segment 112 may include a bottom wall 1121, which has a protrusion 1122. The protection mechanism 400 may include a movable member 410 and an elastic member 420. The movable member 410 is rotatably connected to the base 100 and partially located in the second segment 112. The movable member 410 has an extreme position abutting the protrusion 1122. The elastic member 420 is used to apply an elastic force to the movable member 410 to keep the movable member 410 in the extreme position or to have a tendency to rotate toward the extreme position.

[0085] The protrusion 1122 can be a boss on the bottom wall 1121, or a protrusion or other structure. The protrusion 1122 is used to block the moving part 410, allowing the protective mechanism 400 to move to its maximum position. That is, the protrusion 1122 allows the moving part 410 to move only to its maximum position in the opposite direction to the movement of the wire tube 2, preventing foreign objects from entering the second section 112, and thus preventing the user's fingers or other objects from contacting the cutting device 300.

[0086] The elastic element 420 can be adopted as follows: Figure 4 The torsion spring shown can also be made of other structures such as a tension spring. For example... Figure 2 and Figure 3 As shown, when the wiring channel 110 is not equipped with the wire gauge tube 2, the elastic element 420 can keep the movable element 410 in its extreme position. For example... Figure 1 As shown, when the wire tube 2 is placed in the wiring channel 110, the elastic member 420 can rotate toward the limit position through the movable member 410, and press the wire tube 2 to the limit position.

[0087] See Figure 3 In some embodiments, the second segment 112 further includes a sidewall 1123 opposite to the protective mechanism 400; the movable member 410 has a free end 411 near the sidewall 1123; when the movable member 410 is in its extreme position, the gap d2 between the free end 411 and the sidewall 1123 is greater than or equal to 0.1 mm and less than or equal to 1.5 mm. For example, it can be 0.1 mm, 0.2 mm, 0.3 mm, 0.4 mm, 0.5 mm, 0.6 mm, 0.7 mm, 0.8 mm, 1 mm, 1.2 mm, 1.4 mm, 1.5 mm, etc.

[0088] It should be noted that by providing a protrusion 1122 on the bottom wall 1121, a gap can be reserved between the free end 411 and the side wall 1123. This reserved gap allows the wire tube 2 to easily extend from the wiring channel 110. Considering that some people, such as children, have relatively slender fingers, the gap is set to be smaller. This prevents thinner fingers from directly inserting into the wiring channel 110 through the gap and being cut by the cutting device 300, further reducing the risk of user injury.

[0089] Please continue reading Figure 3 In some embodiments, when the movable member 410 is in its extreme position, the distance d3 between the free end 411 and the outlet end 1120 is greater than or equal to 50 mm. For example, it can be 50 mm, 55 mm, 60 mm, 65 mm, 70 mm, etc.

[0090] Considering that the user may move the movable part 410 away from its extreme position, thus exposing the second section 112, such as Figure 3As shown, the user may apply a rightward force to the movable part 410, causing it to rotate in the direction of movement of the wire marking tube 2, thus exposing the second section 112. Therefore, to prevent the user from being cut by the cutting device 300 after inserting the movable part 410 into the second section 112 from the outlet end 1120, this embodiment sets the distance d3 between the free end 411 and the outlet end 1120 to be relatively long, i.e., not less than 50mm. In this way, even if the user inserts the movable part 410 into the second section 112, they cannot contact the cutting device 300, thereby further reducing the risk of the user being cut. At the same time, considering the space limitations and material costs of the wire marking printer 1, the distance d3 between the free end 411 and the outlet end 1120 should not be too long. Designers can choose an appropriate size according to actual needs, and this embodiment does not impose a specific limitation on this.

[0091] See Figure 5 and Figure 6 In some embodiments, the cutting device 300 includes an anvil 310 and a tube cutting assembly 320. The tube cutting assembly 320 includes a base 321 and a cutter 322 and a cover 323 connected to the base 321. The cover 323 covers the top of the cutter 322.

[0092] In the pipe cutting assembly 320, the base 321 provides a mounting base for the cutting blade 322. The cutting blade 322 is positioned opposite the anvil 310. When cutting the wire tube 2, driven by external force, the cutting blade 322 moves towards the anvil 310 and presses against it to cut. The anvil 310 has switchable full-cut and half-cut surfaces. The full-cut surface of the anvil 310 is a flat plane. When the pipe cutting assembly 320 cuts the wire tube 2 with the full-cut surface, it can achieve a complete cut of the wire tube 2, completely severing it and separating it completely. The half-cut surface of the anvil 310 is only partially flat. When the pipe cutting assembly 320 cuts the wire tube 2, it can only achieve a partial cut, not a complete severance.

[0093] Understandably, when the cover 200 is opened to expose the cutting device 300, the cover 323 located on top of the cutter 322 can shield the blade 3221 of the cutter 322. This isolates the user from the blade 3221 when using or maintaining the line printer 1, preventing accidental contact and cuts by the user (e.g., fingers). The cover 323 and the base 321 can be separate structures, with the cover 323 connected to the base 321 via snap-fit, screw-fit, or adhesive bonding. Alternatively, the cover 323 and the base 321 can be an integral structure, formed by injection molding, additive manufacturing, or other methods.

[0094] See Figure 7In some embodiments, the cover 323 includes a body portion 3231 and an extension portion 3232. The body portion 3231 is connected to the base 321; the extension portion 3232 is connected to the body portion 3231, and the extension portion 3232 extends toward the anvil 310 in the extending direction X and extends beyond the blade 3221 of the cutter 322.

[0095] Considering that when using or maintaining the line marking printer 1, users may approach the blade 3221 from the top of the cover 323 downwards or from the side of the cover 323, this embodiment of the application further provides an extension 3232 extending in the extension direction X, based on the main body 3231 of the cover 323. When a person approaches the blade 3221 from the side of the cover 323, the extension 3232 can block the person, better preventing the person from being cut.

[0096] See Figure 7 In some embodiments, the distance d5 between the end of the extension 3232 and the blade 3221 is greater than or equal to 5 mm and less than or equal to 15 mm. For example, it can be 5 mm, 8 mm, 10 mm, 12 mm, 15 mm, etc. In order to achieve effective blocking of the human body by the extension 3232, the distance between the end of the extension 3232 and the blade 3221 should not be too small. If the distance is less than 5 mm, even if the extension 3232 blocks the human body, the human body will still be cut by touching the blade 3221 due to inertia. In addition, considering the space limitations and material costs of the line number printer 1, the length of the extension 3232 should not be too long, and the distance between the end of the extension 3232 and the blade 3221 should be less than or equal to 15 mm.

[0097] See Figure 5 and Figure 6 In some embodiments, the dimension of the cover 323 along the thickness direction of the cutter 322 is greater than the thickness dimension of the cutter 322.

[0098] Considering that when using or maintaining the line marking printer 1, users may approach the blade 3221 from the top or side of the cover 323, or from the front or back of the cover 323, the thickness of the cover 323 is set to be greater than the thickness of the cutter 322 in this embodiment of the application, so as to further reduce the risk of users being cut.

[0099] See Figure 5 In some embodiments, the dimension d4 of the cover member 323 along the thickness direction of the cutter member 322 is greater than or equal to 2 mm and less than or equal to 15 mm. For example, it can be 2 mm, 5 mm, 8 mm, 10 mm, 12 mm, 15 mm, etc.

[0100] To effectively reduce the risk of cuts to users, the thickness of the cover 323 should not be too small. When the thickness of the cover 323 along the cutting blade 322 is greater than 2mm, the cover 323 can effectively block the human body when it approaches the blade 3221 from the front or back of the cover 323, thus better preventing cuts. Furthermore, considering the space limitations and material costs of the line marking printer 1, the width of the cover 323 should also not be too wide; the dimension of the cover 323 along its thickness direction Z should be less than or equal to 15mm.

[0101] See Figure 8 When the cover 323 is located at one edge of the cover 323 in its thickness direction, the risk of the user being cut by the cover 323 increases significantly. Therefore, in some embodiments, the distance d6 between the orthographic projection of the cutter 322 onto the cover 323 and the geometric center line 3233 of the extension 3232 along the extension direction X is greater than or equal to 0 mm and less than or equal to 0.3 mm. For example, it can be 0.1 mm, 0.15 mm, 0.2 mm, 0.25 mm, 0.3 mm, etc. In this way, the cutter 322 can be positioned as close as possible to the middle of the extension 3232, effectively protecting the user approaching the blade 3221 from the front-rear direction of the cover 323, preventing the cover 323 from approaching one edge of the cover 323 in its thickness direction, and greatly reducing the risk of the user being cut.
