[0004] In the above solution, the flue gas is collected and filtered through a flue gas treatment box, a blower, a three-way pipe, activated carbon adsorption cotton, and a fume extraction hood. This results in the following drawback: the activated carbon adsorption cotton in the flue gas treatment box requires the machine to be shut down when it is replaced. Utility Model Content

[0005] The purpose of this invention is to provide a cable laser printing device to solve the problem that the machine needs to be stopped when replacing the activated carbon adsorption cotton in the flue gas treatment box.

[0006] To achieve the above-mentioned utility model objectives, the present utility model adopts the following technical solution: a cable laser printing device, including a box door, which is rotatably connected to the front side of the outer wall of a printing box via a hinge. Two fume treatment boxes are fixed on the top surface of the printing box. A PLC controller is fixed on the right side of the outer wall of the printing box. A laser printer is fixed on the bottom surface inside the printing box. An exhaust hood is fixed on the outer wall of the laser printer. A three-way pipe is fixedly connected between the two fume treatment boxes. The other end of the three-way pipe passes through the printing box and is fixedly connected to the rear side of the exhaust hood. A sealing cover is rotatably connected to the top surface of each of the two fume treatment boxes via a hinge. Activated carbon adsorption cotton is provided inside each of the two fume treatment boxes. An exhaust fan is fixed on the top surface of the printing box. The exhaust fan is electrically connected to the PLC controller. A connecting pipe is fixed to the input end of the exhaust fan. Suction pipes are fixedly connected between each of the two fume treatment boxes and the connecting pipe. Valves are provided on each of the two suction pipes. The valves are electrically connected to the PLC controller.

[0007] Preferably, a first sealing ring is fixed to the right side of the box door, and a second sealing ring is fixed to the bottom surface of both sealing covers.

[0008] Preferably, the top surfaces of the two flue gas treatment boxes are respectively provided with snap-fit ​​holes, and the bottom surfaces of the two sealing covers are respectively fixed with elastic snap-fit ​​blocks, and the two elastic snap-fit ​​blocks are respectively detachably snapped into the two snap-fit ​​holes.

[0009] Preferably, the bottom surface of the printing box is detachably equipped with several guide frames, and each of the guide frames is rotatably equipped with a guide wheel.

[0010] Preferably, the bottom surface of the printing box has several threaded grooves, and mounting plates are fixed to the front and rear sides of several guide frames respectively. The top surfaces of two mounting plates are respectively provided with threaded holes, and bolts are threaded into the two threaded holes respectively. The threaded ends of the bolts are threaded into the internal threads of the threaded grooves.

[0011] Preferably, an observation hole is provided on one side of the box door, and glass is fixed inside the observation hole.

[0012] Compared with the prior art, a cable laser printing device using the above technical solution has the following advantages:

[0013] Beneficial effects:

[0014] 1. In use, through the coordinated action of the cabinet door, printing box, fume treatment box, PLC controller, laser printer, fume extraction hood, three-way pipe, sealing cover, activated carbon adsorption cotton, exhaust fan, connecting pipe, suction pipe and valve, the effective collection and filtration of fume during the laser printing of cables is achieved. At the same time, the activated carbon adsorption cotton can be replaced without stopping the machine, which improves production efficiency, reduces the impact on the environment and protects the health of the staff.

[0015] Second, during use, the first sealing ring tightly fits the edge of the printing chamber opening, forming a reliable sealing barrier. This effectively reduces the leakage of fumes generated inside the printing chamber during laser printing into the external environment. When the sealing cover is closed, the second sealing ring makes tight contact with the top opening of the fume treatment chamber, ensuring that the inside of the fume treatment chamber is sealed. During the exhaust fan's operation, this prevents fumes from leaking from the connection between the sealing cover and the fume treatment chamber, ensuring that all fumes pass through the activated carbon adsorption cotton for filtration, thus improving the fume treatment effect. No additional tools are required, saving operation time, improving work efficiency, and allowing staff to quickly replace and maintain the activated carbon adsorption cotton, ensuring the normal operation of the fume treatment system.

[0016] Thirdly, during use, when the guide frame or guide wheels are damaged and require maintenance or replacement, the operator only needs to unscrew the bolts from the threaded holes and grooves to remove the guide frame from the inside of the printing chamber for easy maintenance or replacement. The observation hole and glass provide a convenient viewing window for the operator. Without opening the chamber door, the operator can clearly observe the internal conditions of the printing chamber through the glass, including the movement of cables, the operation of the laser printer, and fume treatment, without frequently opening the chamber door.

[0023] The preferred embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0024] like Figures 1-5 As shown, a cable laser printing device includes a door 1, which is hinged to the front of the outer wall of a printing box 2. Two fume treatment boxes 3 are fixed to the top surface of the printing box 2. A PLC controller 4 (Siemens S7-200) is fixed to the right side of the outer wall of the printing box 2. A laser printer 5 is fixed to the bottom surface inside the printing box 2. A fume extraction hood 6 is fixed to the outer wall of the laser printer 5. A T-connector 7 connects the two fume treatment boxes 3, with the other end of the T-connector 7 penetrating the printing box 2. The exhaust hood 6 is fixed to the rear side of the two flue gas treatment boxes 3. The top surfaces of the two flue gas treatment boxes 3 are rotatably connected to the sealing cover 8 via hinges. The interior of the two flue gas treatment boxes 3 is equipped with activated carbon adsorption cotton 9. The top surface of the printing box 2 is fixed with an exhaust fan 10. The exhaust fan 10 is electrically connected to the PLC controller 4. The input end of the exhaust fan 10 is fixed with a connecting pipe 11. The two flue gas treatment boxes 3 are connected to the connecting pipe 11 with a suction pipe 12. The two suction pipes 12 are equipped with valves 13. The valves 13 are electrically connected to the PLC controller 4.

[0025] In use, when the operator inserts the cable from the left side of the outer wall of the printing box 2 and then exits from the right side, and closes the box door 1, when the cable is below the laser printer 5, the laser printer 5 is started through the PLC controller 4 to print words on the cable. During the printing process, a large amount of smoke is generated. In the initial state, the valve 13 of the suction pipe 12 on the left smoke treatment box 3 is closed, and the valve 13 of the suction pipe 12 on the right smoke treatment box 3 is open. The operator starts the exhaust fan 10 through the PLC controller 4. The exhaust fan 10 starts working and generates strong suction. The smoke is quickly drawn into the three-way pipe 7 by the exhaust hood 6, and then enters the smoke treatment box 3 on the right. The activated carbon adsorption cotton 9 in the smoke treatment box 3 adsorbs and filters the harmful substances and odors in the smoke. The clean air after treatment is discharged outside the device through the suction pipe 12, connecting pipe 11 and exhaust fan 10 on the right smoke treatment box 3, effectively avoiding the impact of smoke on the environment and the health of the operators.

[0026] When the staff needs to replace the activated carbon adsorption cotton 9, there is no need to stop the machine, which improves production efficiency. The valve 13 of the suction pipe 12 on the left flue gas treatment box 3 is opened by the PLC controller 4, and the valve 13 of the suction pipe 12 on the right flue gas treatment box 3 is closed at the same time. The flue gas flow direction changes immediately. After being drawn into the three-way pipe 7 by the exhaust hood 6, it enters the flue gas treatment box 3 on the left. After being adsorbed and filtered by the activated carbon adsorption cotton 9 inside, the clean air is discharged through the suction pipe 12, connecting pipe 11 and exhaust fan 10 on the left flue gas treatment box 3. During this process, the staff can open the sealing cover 8 on the right flue gas treatment box 3 to replace the used activated carbon adsorption cotton 9 inside the right flue gas treatment box 3. The replacement of the activated carbon adsorption cotton 9 inside the left flue gas treatment box 3 is the same, which makes it convenient and quick to replace the activated carbon adsorption cotton 9 during continuous operation of the device, ensuring that the flue gas treatment effect is always good.

[0027] Through the coordinated action of the box door 1, printing box 2, fume treatment box 3, PLC controller 4, laser printer 5, fume extraction hood 6, three-way pipe 7, sealing cover 8, activated carbon adsorption cotton 9, exhaust fan 10, connecting pipe 11, suction pipe 12 and valve 13, the fume in the process of laser printing on cables is effectively collected and filtered. At the same time, the activated carbon adsorption cotton 9 can be replaced without stopping the machine, which improves production efficiency, reduces the impact on the environment and protects the health of the staff.

[0028] like Figures 1-3 As shown, a first sealing ring 14 is fixed on the right side of the box door 1, and a second sealing ring 15 is fixed on the bottom surface of both sealing covers 8.

[0029] During use, when the door 1 is closed, the first sealing ring 14 can tightly fit the edge of the opening of the printing box 2, forming a reliable sealing barrier, which effectively reduces the leakage of smoke generated inside the printing box 2 during the laser printing process into the external environment. When the sealing cover 8 is closed, the second sealing ring 15 is in close contact with the top opening of the smoke treatment box 3, ensuring that the inside of the smoke treatment box 3 is sealed. During the exhaust process of the exhaust fan 10, it prevents smoke from leaking from the connection between the sealing cover 8 and the smoke treatment box 3, ensuring that all the smoke can be filtered through the activated carbon adsorption cotton 9, thus improving the smoke treatment effect.

[0030] like Figures 1-3 and Figure 5 As shown, the top surfaces of the two flue gas treatment boxes 3 are respectively provided with snap-fit ​​holes 16, and the bottom surfaces of the two sealing covers 8 are respectively fixed with elastic snap-fit ​​blocks 17. The two elastic snap-fit ​​blocks 17 are respectively detachably snapped into the two snap-fit ​​holes 16. The bottom surface of the printing box 2 is detachably equipped with several guide frames 18, and the interior of the several guide frames 18 is respectively provided with rotatable guide wheels 19.

[0031] During use, when the operator closes the sealing cover 8, they simply press it down against the top of the flue gas treatment box 3. The elastic locking block 17 will deform under its own elasticity and smoothly engage with the locking hole 16, thus achieving a firm connection between the sealing cover 8 and the flue gas treatment box 3. This ensures that the sealing cover 8 is tightly closed and prevents flue gas leakage. When it is necessary to open the sealing cover 8 to replace the activated carbon adsorption cotton 9, the operation is equally simple. The operator only needs to squeeze the elastic locking block 17 or pull the sealing cover 8 upwards to apply a certain external force to deform the elastic locking block 17 and disengage it from the locking hole 16, thereby opening the sealing cover 8. No additional tools are required, saving operation time, improving work efficiency, and facilitating the operator to quickly replace and maintain the activated carbon adsorption cotton 9, ensuring the normal operation of the flue gas treatment system. First, the finished cable is inserted into the left end of the printing box 2 under the action of the external traction device. Then, it passes through several guide wheels 19 on the guide frame 18 in sequence for guidance and tensioning, which can improve the printing effect. After that, the cable exits from the right end of the printing box 2.

[0032] like Figure 1 , Figure 2 and Figure 5 As shown, the bottom surface of the printing box 2 has several threaded grooves 20. The front and rear sides of several guide frames 18 are respectively fixed with mounting plates 21. The top surfaces of the two mounting plates 21 are respectively provided with threaded holes 22. Bolts 23 are threadedly connected to the two threaded holes 22 respectively. The threaded end of the bolt 23 is threadedly connected to the inside of the threaded groove 20. An observation hole 24 is provided on one side of the box door 1. A glass 25 is fixed inside the observation hole 24.

[0033] During use, when it is necessary to install the guide frame 18 and the guide wheel 19, the operator only needs to place the guide frame 18 in a suitable position on the bottom surface inside the printing box 2, aligning the threaded hole 22 on the mounting plate 21 with the threaded groove 20, and then pass the bolt 23 through the threaded hole 22 and screw it into the threaded groove 20 to complete the installation and fixation of the guide frame 18. The operation is simple and quick, ensuring that the guide frame 18 is installed firmly and stably. When the guide frame 18 or the guide wheel 19 is damaged and needs maintenance or replacement, the operator only needs to unscrew the bolt 23 from the threaded hole 22 and the threaded groove 20 to remove the guide frame 18 from the inside of the printing box 2 for easy maintenance or replacement. The observation hole 24 and the glass 25 provide the operator with a convenient observation window. The operator can clearly observe the inside of the printing box 2 through the glass 25 without opening the box door 1, including the movement of the cables, the operation of the laser printer 5, and the fume treatment, without frequently opening the box door 1.

[0034] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
