Description

Technical Field

[0001] This application relates to the field of rewinding printing substrates, and more specifically, to a laser printing rewinding pretreatment machine with a cleaning mechanism. Background Technology

[0002] Laser printing rewinding pre-processing equipment is a specialized device designed for pre-processing laser printing materials before the rewinding process. Rewinding enables the neat and standardized storage of materials. During the initial storage or transportation, the roll material may experience problems such as loose winding, uneven edges, or even wrinkles due to various factors. The rewinding device neatly and tightly rewinds the material onto the reel, forming a standardized roll shape, thereby improving rewinding efficiency and the quality stability of the final product.

[0003] Chinese patent application number 202123189045.2 discloses a label rewinding structure for a backless printer. This label rewinding mechanism is located at the paper outlet of the paper feed channel and includes a drive device, a rotating shaft located at the output end of the drive device, and a paper roll core sleeved on and detachably connected to the rotating shaft. The paper roll core is made of silicone. The label rewinding structure of this utility model rewinds the printed backless labels by driving the rotating shaft and paper roll core to rotate, allowing for unified use later. Furthermore, the silicone material of the paper roll core facilitates reuse.

[0004] The above solution has the following shortcomings: During use, the rotating shaft and paper roll core are driven by a drive device to rewind the substrate. However, the roll material to be processed is prone to loosening during the initial storage or transportation process, resulting in dust on the surface of the substrate. The existing device does not have the effect of cleaning the substrate. In subsequent printing, the dust on the surface of the substrate will affect the printing effect. Therefore, it needs to be improved. Utility Model Content

[0005] To overcome the above shortcomings, this application provides a laser printing rewinding pretreatment machine with a cleaning mechanism, which aims to improve the problem that dust adhering to the substrate surface affects the printing effect and reduces the practicality of the device.

[0006] This application provides a laser printing rewinding pretreatment mechanical device with a cleaning mechanism, including a guide frame for support and unwinding and rewinding frames at both ends of the guide frame. The top of the guide frame is also provided with a dust blowing box for cleaning the substrate and a suction box for use in conjunction with the dust blowing box. The tail end of the suction box is also provided with a wiping box for further cleaning. There are two sets of the dust blowing box, suction box and wiping box, and the substrate is located in the gap between them.

[0007] In one specific implementation, a driving device is provided on the top of both the unwinding frame and the rewinding frame. The top of the unwinding frame has an unwinding roller and a first transmission roller for conducting the substrate, and the top of the rewinding frame has a rewinding roller and a second transmission roller for conducting the substrate.

[0015] In one specific implementation, the suction box has an inlet shovel on the side near the soot blowing box, and a cavity is provided inside it. The suction box has suction ports at both ends, and the suction ports extend to the outside of the bracket two.

[0016] In the above process, impurities are guided into the suction box cavity by an inlet shovel, and the suction ports at both ends are connected to external negative pressure equipment to remove the impurities, thereby achieving centralized collection of dust and debris blown up by the dust blowing box and preventing secondary contamination of the substrate.

[0017] In one specific implementation, the suction box is disposed on a welding plate on the side away from the blowing box, wherein the wiping box is welded to one side of the suction box via the welding plate.

[0018] In the above process, the wiping box is fixed to one side of the suction box by welding plate, so that the wiping box is at the process node after suction cleaning, forming a continuous cleaning sequence of blowing, suction and wiping, and improving the cleaning integrity.

[0019] In one specific implementation, the top of the wiping box is provided with a water guide pipe, and the bottom side of the wiping box is provided with a water suction pipe, wherein the sides of the water guide pipe and the water suction pipe are provided with water flow interfaces.

[0020] In the above process, cleaning fluid is introduced through a water pipe and waste fluid is discharged through a water pump. The water flow interface is connected to an external water source and drainage system to provide liquid circulation support for wiping and cleaning of the wiping box and ensure the humid environment required for wiping.

[0038] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments.

[0039] Please see Figure 1-8 This application provides a laser printing rewinding pretreatment mechanical equipment with a cleaning mechanism, including a guide frame 1 for support and an unwinding frame 11 and a rewinding frame 12 integrally welded at both ends. The top of the unwinding frame 11 and the rewinding frame 12 are both fixed with a driving device. The top of the unwinding frame 11 has an unwinding roller 111 and a transmission roller 112 for conducting the substrate rotatably through a bearing seat. The top of the rewinding frame 12 is correspondingly provided with a rewinding roller 121 and a transmission roller 122. The unwinding roller 111 and the transmission roller 112, and the rewinding roller 121 and the transmission roller 122 are all driven synchronously by the driving device to ensure the continuity of the pretreatment process.

[0040] Tensioning frames 2 are symmetrically welded to the top of the guide frame 1 near the unwinding frame 11 and the rewinding frame 12. Tensioning rollers are installed on the inner side of the tensioning frame 2 through a slider rail structure. The tensioning frame 2 is equipped with a spring buffer assembly inside, which can automatically adjust the tension according to the tension of the substrate. The substrate is stretched and tightened above the guide frame 1 by the tensioning frame 2 to avoid wrinkles and deviations during the transmission process, and to provide a flat treatment base for subsequent cleaning operations.

[0041] The top of the guide frame 1 is bolted with a bracket 33. The two sides of the dust blowing box 3 are integrally formed with mounting brackets 32. The mounting brackets 32 have waist-shaped holes on their surfaces. The dust blowing box 3 is threadedly connected to the bracket 33 through the mounting brackets 32. The height can be finely adjusted through the waist-shaped holes to adapt to substrates of different thicknesses. The sides of the dust blowing box 3 have strip-shaped nozzles 31 evenly distributed along the width of the substrate. The nozzles 31 are inclined towards the surface of the substrate and have an airflow distribution chamber inside to ensure that the air pressure of each nozzle 31 is uniform. By connecting to an external air compressor, high-pressure airflow is blown out to achieve the initial cleaning of floating dust and debris on the surface of the substrate.

[0042] The top of the guide frame 1 is fixed with a second bracket 44 located downstream of the soot blowing box 3. The suction box 4 has connecting ear plates 43 with mounting holes welded on both sides. The suction box 4 is threadedly fixed to the second bracket 44 through the connecting ear plates 43. The suction box 4 has an upwardly inclined guide shovel 41 on the side near the soot blowing box 3. The edge of the guide shovel 41 is designed with rounded corners to fit the surface of the substrate and avoid scratching the substrate. It has a funnel-shaped cavity inside, and suction ports 42 are symmetrically arranged at both ends of the suction box 4. The suction ports 42 extend to the outside of the second bracket 44 and are connected to a negative pressure fan. The impurities blown up by the soot blowing box 3 can be sucked into the cavity through the guide shovel 41 and discharged and collected through the suction ports 42 to prevent the impurities from secondary contaminating the substrate.

[0043] A welding plate 6 is welded to the side of the suction box 4 away from the blowing box 3. The wiping box 5 is rigidly connected to the suction box 4 through the welding plate 6, forming a continuous cleaning path of blowing, suction and wiping. The blowing box 3, suction box 4 and wiping box 5 are arranged in two sets along the substrate conveying direction. The front set focuses on preliminary cleaning and the rear set performs deep cleaning. The substrate passes horizontally through the gap between the two sets of cleaning mechanisms to ensure double-sided cleaning without dead corners.

[0044] The side wall of bracket 2 44 is fixed with a motor frame 55 by bolts. A stepper motor is mounted on the surface of the motor frame 55. A rotating roller is fixed to the output end of the stepper motor through a coupling. The axis of the rotating roller is perpendicular to the transmission direction of the substrate. The surface of the rotating roller is covered with a layer of high-density microfiber wiping cotton 56. The wiping cotton 56 can be removed and replaced by Velcro for easy regular maintenance. Spring adjustment brackets are provided at both ends of the rotating roller, which can finely adjust the contact pressure with the substrate according to the thickness of the substrate to ensure the wiping effect while avoiding damage to the substrate.

[0045] The top of the wiping box 5 is equipped with a water guide pipe 51, and the bottom is equipped with a corresponding water suction pipe 52. Both the water guide pipe 51 and the water suction pipe 52 have quick-connect water inlets 53 on their sides, which are connected to an external cleaning fluid supply system and a waste fluid recovery device, respectively, to provide continuous liquid circulation support for the wiping process. The inside of the wiping box 5 is equipped with an inclined water receiving groove. A squeegee 54 is fixed to the edge of the water receiving groove by bolts. The blade of the squeegee 54 is in close contact with the surface of the wiping cotton 56 to remove cleaning fluid and impurities from the wiping cotton 56. The inside of the water receiving groove is equipped with multiple sets of droppers connected to the water guide pipe 51. The dropper outlets are located above the wiping cotton 56 to supply liquid to the wiping cotton 56, thereby cleaning the wiping cotton 56. At the bottom of the water receiving groove is a suction pipe connected to the water suction pipe 52. A filter screen is provided at the inlet of the suction pipe to filter impurities and pump the waste liquid to the recovery device, realizing the recycling of cleaning fluid and continuous cleaning of the wiping cotton 56, maintaining a stable wiping effect.

[0046] The working principle of this laser printing rewinding pretreatment mechanical equipment with a cleaning mechanism is as follows: When the device is working, the unwinding roller 111 of the unwinding frame 11 releases the substrate, which is transmitted to the guide frame 1 via the transmission roller 112. The tensioning roller of the tensioning frame 2 automatically adjusts the tension to flatten and tighten the substrate. The substrate first passes through the first set of dust blowing boxes 3, where the strip-shaped blowing nozzle 31 blows out high-pressure airflow to sweep away surface dust. Impurities are introduced into the cavity by the guide shovel 41 of the suction box 4 with the airflow and are sucked away by the negative pressure equipment connected to the suction interface 42. Then the substrate enters the wiping box 5, where the stepper motor drives the rotating roller to rotate the wiping cotton 56. The water guide pipe 51 supplies liquid to the wiping cotton 56 through the drip pipe, and the scraper 54 scrapes off the excess liquid. The waste liquid is recovered by the water collection tank and the water suction pipe 52. After the two sets of cleaning mechanisms complete the preliminary and deep cleaning in sequence, the substrate is transmitted to the rewinding roller 121 of the rewinding frame 12 via the transmission roller 122 to complete the rewinding, realizing efficient pretreatment of the substrate before laser printing.

[0047] The above are merely specific embodiments of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
