Description

Technical Field

[0001] This utility model belongs to the field of cable processing technology, and more specifically, it relates to a cable processing inkjet printing device. Background Technology

[0002] In the cable processing and manufacturing industry, to achieve product traceability, specification differentiation, and quality control, it is necessary to print key information such as model, specifications, production date, and manufacturer on the cable surface. Laser printing technology, due to its advantages such as high coding clarity, strong wear resistance, high printing efficiency, and no consumable pollution, has become the mainstream technology for printing information on cable surfaces and is widely used in various cable processing production lines.

[0003] However, during laser printing, the surface material of the cable generates fumes and fine particulate matter under high temperatures. If these pollutants are directly emitted into the workshop environment, they will not only affect the air quality of the production environment but may also harm the health of operators. Some cable processing and printing equipment uses simple exhaust devices for crude smoke extraction, which makes it easy for fumes to diffuse into the workshop operating environment and affect the air quality. Therefore, in view of this, we have studied and improved the existing structure and its shortcomings to provide a cable processing and printing equipment with greater practical value. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a cable processing inkjet printing device, which is achieved by the following specific technical means: A cable processing inkjet printing device includes an inkjet printing table and a bracket mounted on the inkjet printing table. A laser inkjet head is mounted on the bracket. A fume treatment component is provided on the inkjet printing table. The fume treatment component includes a fume hood, a fume extraction pipe, a purification housing, and a centrifugal fan. The fume hood is fixedly installed at the upper middle part of the inkjet printing table. A through hole is opened in the middle of the upper surface of the fume hood, and the through hole is located directly below the laser inkjet head. Cable through holes are symmetrically opened on both sides of the fume hood. Both ends of the fume extraction pipe are fixedly inserted into the fume hood, and fume extraction hoods are fixedly installed at both ends. Two fume extraction hoods are distributed on both sides of the fume hood and are staggered. An air inlet pipe and an air outlet pipe are fixedly installed at both ends of the purification housing, respectively. The exhaust end of the centrifugal fan is connected to the fume extraction pipe, and the intake end is connected to the air inlet pipe. A pre-filter, an activated carbon filter, and a HEPA filter are arranged sequentially from the air inlet pipe to the air outlet pipe inside the purification housing.

[0005] Furthermore, the bottom surface of the inner wall of the purification housing has three grooves, and the upper surface has three mounting holes.

[0006] Furthermore, the pre-filter, activated carbon filter, and HEPA filter are respectively inserted into the purification housing through the installation port, and their bottoms are respectively inserted into the grooves.

[0007] Furthermore, each of the pre-filter, activated carbon filter, and HEPA filter has a mounting plate fixedly installed at its top. Each mounting plate is located at the top of the purification housing, and a sealing ring is provided between the mounting plate and the purification housing.

[0008] Furthermore, a positioning groove is provided in the middle of the upper surface of each mounting plate, and a pressure plate is movably sleeved on the upper end of the purification housing. The pressure plate is inserted into the positioning groove and is inverted U-shaped. The pressure plate is fixed to the purification housing by screws.

[0009] Furthermore, a plate body one and a set of plate bodies two are fixedly installed on both sides of the smoke collection hood. Two rotating rollers one are rotatably installed on each plate body one, and two rotating rollers two are rotatably installed between each set of plate bodies two. Each rotating roller two is arranged horizontally, and each rotating roller one is arranged vertically.

[0010] Compared with the prior art, the present invention has the following beneficial effects: 1. The fume treatment component in this cable processing inkjet printing equipment adopts a "closed fume collection + staggered suction" design: the fume collection hood forms a relatively closed printing space (only allowing the cable to enter and exit through the cable perforation), which can reduce the premature diffusion of fume; the fume extraction hoods at both ends of the extraction pipe are staggered (located on both sides inside the fume collection hood), which, together with the negative pressure generated by the centrifugal fan, increases the range of fume extraction; at the same time, the centrifugal fan starts synchronously with the laser printing head and shuts off after a delay after printing stops, which can thoroughly remove the residual fume in the fume collection hood and extraction pipe, effectively preventing fume leakage into the workshop environment and protecting the health of operators.

[0011] II. The purification housing features a three-stage purification structure, consisting of a pre-filter, an activated carbon filter, and a HEPA filter, arranged sequentially from the inlet pipe to the outlet pipe. The pre-filter removes large particulate impurities from the flue gas, preventing clogging of subsequent filters. The activated carbon filter uses its porous structure to adsorb VOCs and odors, reducing the content of harmful gases. The HEPA filter removes fine particles, achieving deep purification of the flue gas. The three-stage filter works synergistically to ensure that the gas discharged from the outlet pipe meets environmental emission standards, avoiding environmental pollution.

[0012] 3. The purification housing adopts a "top installation + bottom positioning" filter installation structure: the filter can be directly inserted from the top installation port, and the bottom is positioned by a groove to ensure accurate installation; when replacing, only the inverted U-shaped pressure plate (fixed by screws) needs to be removed, and the filter can be taken out by lifting the installation plate at the top of the filter. The operation is simple and convenient, shortening maintenance time. At the same time, the sealing ring set between the installation plate and the purification housing can fill the installation gap to prevent unpurified flue gas from leaking from the installation port, ensuring stable and reliable purification effect.

[0021] Example:

[0022] As attached Figure 1 To be continued Figure 4 As shown: This utility model provides a cable processing inkjet printing device, including an inkjet printing table 1 and a bracket 2 mounted on the inkjet printing table 1. A laser inkjet head 21 is mounted on the bracket 2. A fume treatment assembly is provided on the inkjet printing table 1, which includes a fume hood 3, a fume extraction pipe 4, a purification housing 5, and a centrifugal fan 6. The fume hood 3 is fixedly installed in the middle of the upper end of the inkjet printing table 1. A through hole 31 is opened in the middle of the upper surface of the fume hood 3, which is located directly below the laser inkjet head 21. Cable through holes 3 are symmetrically opened on both sides of the fume hood 3. 2. Both ends of the smoke extraction pipe 4 are fixedly inserted into the smoke collection hood 3, and smoke extraction hoods 41 are fixedly installed at both ends. The two smoke extraction hoods 41 are distributed on both sides inside the smoke collection hood 3 and are staggered. The two ends of the purification housing 5 are respectively fixedly installed with an air inlet pipe 51 and an air outlet pipe 52. The exhaust end of the centrifugal fan 6 is connected to the smoke extraction pipe 4, and the air inlet end is connected to the air inlet pipe 51. The purification housing 5 is provided with a primary filter 53, an activated carbon filter 54 and a HEPA filter 55 in sequence from the air inlet pipe 51 to the air outlet pipe 52. The bottom surface of the inner wall of the purification housing 5 has three grooves 56, and the upper surface has three mounting holes 57. The pre-filter 53, activated carbon filter 54 and HEPA filter 55 are respectively inserted into the purification housing 5 through the installation port 57, and their bottoms are respectively inserted into the grooves 56; The top of the pre-filter 53, activated carbon filter 54 and HEPA filter 55 are all fixedly installed with mounting plates 7. Each mounting plate 7 is located at the top of the purification housing 5, and a sealing ring 72 is provided between the mounting plate 7 and the purification housing 5. Each mounting plate 7 has a positioning groove 71 in the middle of its upper surface. A pressure plate 73 is movably fitted on the upper end of the purification housing 5. The pressure plate 73 is inserted into the positioning groove 71. The pressure plate 73 is inverted U-shaped and is fixed to the purification housing 5 by screws. Both sides of the smoke hood 3 are fixedly installed with a plate 8 and a set of plates 9. Each plate 8 has two rotating rollers 81 rotatably installed on it, and each set of plates 9 has two rotating rollers 91 rotatably installed between them. Each rotating roller 91 is arranged horizontally, and each rotating roller 81 is arranged vertically.

[0023] The working principle of this embodiment: Step 1: Before operation, align one end of the cable to be printed with the cable through holes 32 symmetrically opened on both sides of the smoke hood 3. The vertically arranged roller 81 on the plate 1 8 fits against the two side walls of the cable to limit the lateral deviation of the cable (avoid left and right swaying). The horizontally arranged roller 91 between the plates 2 9 fits against the upper and lower surfaces of the cable to limit the vertical displacement of the cable (avoid up and down jumping). Both roller 81 and roller 91 are rotating structures and rotate synchronously with the cable conveyor to ensure the stability of the cable posture. The cable is driven to move at a uniform speed in the horizontal direction by the external traction mechanism (or the equipment matching conveyor components) so that the cable continuously passes through the inside of the smoke hood 3. Step 2: When the cable is delivered to the printing area inside the fume hood 3 (i.e., directly below the laser printing head 21, corresponding to the through hole 31 on the upper surface of the fume hood 3), the laser printing head 21 on the bracket 2 is activated, emitting a laser beam through the through hole 31 onto the cable surface. Information printing is completed according to preset parameters (such as model, specifications, and production date). The laser energy acts on the cable insulation / sheath material, causing localized high-temperature vaporization of the material, generating smoke containing carbon particles and volatile organic compounds (VOCs). The smoke diffuses directly into the enclosed space inside the fume hood 3 (the fume hood 3 is a relatively sealed structure, connected to the outside only through the cable perforation 32, reducing premature smoke leakage). The centrifugal fan 6, which starts synchronously with the laser printing head 21, has its exhaust end connected to the smoke extraction pipe 4. The exhaust creates a negative pressure inside the smoke extraction pipe 4 and the fume hood 3. Both ends of the smoke extraction pipe 4 are fixedly inserted... Inside the smoke collection hood 3, the smoke extraction hoods 41 at the ends are staggered to increase the range of smoke extraction and ensure efficient smoke extraction. The smoke drawn into the smoke extraction hood 41 is transported to the exhaust end of the centrifugal fan 6 through the smoke extraction pipe 4 and discharged from the intake end of the centrifugal fan 6. It is then sent into the purification housing 5 through the intake pipe 51. First, it passes through the pre-filter 53 near the intake pipe 51 to filter out larger particulate impurities in the smoke, preventing large particles from clogging subsequent filters. After the pre-filter, the smoke flows through the activated carbon filter 54. The porous structure of the activated carbon adsorbs volatile organic compounds (VOCs) and some odors in the smoke, reducing the content of harmful gases. Finally, it passes through the HEPA filter 55 near the exhaust pipe 52 to filter out fine particles in the smoke, achieving deep purification of the smoke. The clean gas after three stages of purification is discharged from the equipment through the exhaust pipe 52 at the other end of the purification housing 5. Step 3: When the filter screen has been used for a certain period of time, remove the inverted U-shaped pressure plate 73 at the top of the purification housing 5 (fixed to the purification housing 5 by screws), and take the pressure plate 73 out of the positioning groove 71 of the mounting plate 7; then lift the mounting plate 7 at the top of the filter screen upwards, and the pre-filter 53, activated carbon filter 54, and HEPA filter 55 can be taken out from the corresponding mounting ports 57 respectively; insert the new filter screen into the mounting port 57, and the bottom of the filter screen is inserted into the groove 56 on the bottom surface of the inner wall of the purification housing 5 (to achieve positioning), and then fix the mounting plate 7 with the pressure plate 73 to complete the replacement. The sealing ring 72 set between the mounting plate 7 and the purification housing 5 can fill the installation gap to prevent unpurified flue gas from leaking from the mounting port 57, ensuring that all flue gas is purified by the three-stage filter screen before being discharged.
