Description

Technical Field

[0001] This utility model relates to the field of printing equipment cleaning, and in particular to a printing equipment cleaning component. Background Technology

[0002] In the printing production process, printing rollers, including ink rollers, wet rollers, and blanket roller liners, are the core components for ink and water transfer and printing. Their performance directly determines the quality of printed materials and the stability of production. Even though users follow standard operating procedures and perform regular cleaning and maintenance, the lifespan of printing rollers inevitably tends to shorten, accompanied by a variety of problems that significantly affect printing efficiency and costs.

[0003] Currently, inadequate or untimely cleaning of ink rollers leads to the accumulation of hard impurities such as ink skin and ink residue on the surface. During operation, these impurities continuously rub against the roller surface, exacerbating heat generation and aging, resulting in pitting, especially severe at the ends, and ultimately causing scratches. Because rubber rollers are relatively soft, if hard objects adhere to their surface, they are easily scratched during high-speed operation.

[0004] Therefore, there is an urgent need to develop a high-efficiency and roller-friendly cleaning component for printing equipment to address the shortcomings of existing cleaning methods. Utility Model Content

[0036] This utility model discloses a cleaning component for printing equipment. (Refer to...) Figures 1 to 7 A cleaning component for printing equipment mainly includes a workbench 100, a placement mechanism 200, and a cleaning mechanism 300. The placement mechanism 200 includes a placement platform 210, a placement rack 220, a first motor 230, and a drive roller 240. The placement platform 210 is slidably mounted on the workbench 100 via guide wheels. The placement rack 220 is relatively fixedly mounted on the placement platform 210. The drive roller 240 is relatively rotatably mounted on the placement rack 220. The first motor 230 is fixedly mounted on the placement rack 220 and is connected to the drive roller 240 in a transmission manner. The cleaning mechanism 300 includes a cleaning component 310 and a cleaning rack 320. The cleaning rack 320 is fixedly mounted on the workbench 100. The cleaning component 310 includes a cleaning pipe 311 and nozzles 312. The cleaning pipe 311 is fixedly mounted on the cleaning rack 320. Multiple nozzles 312 are mounted on the cleaning pipe 311. The inlet of the cleaning pipe 311 is connected to a water source.

[0037] The fixing rods at both ends of the printing roller are placed on two drive rollers 240. The two drive rollers 240 support and position one end of the fixing rod, which is convenient for placement and easy to remove after cleaning. Through the cooperation of the drive rollers 240 and the first motor 230, the printing roller rotates automatically during the cleaning process. Combined with the spray system, it achieves 360° cleaning without dead angles. The sliding design of the placement platform 210 facilitates the loading and unloading of the roller body. The fixed installation of the cleaning rack 320 ensures that the nozzle 312 accurately covers the roller surface, which solves the problems of low efficiency and incomplete cleaning of manual cleaning. It is especially suitable for removing dried ink and floating dust impurities from the surface of ink rollers or rubber rollers.

[0038] Reference Figures 1 to 4In some embodiments, two opposing placement racks 220 form a group, and multiple groups of placement racks 220 are installed on the placement platform 210. Two drive rollers 240 are installed on each placement rack 220. Multiple groups of placement racks 220 support the simultaneous cleaning of multiple printing rollers, significantly improving equipment utilization. The design of a single placement rack 220 with a single-sided dual drive roller 240 improves the contact force on the printing roller, avoids roller slippage or deflection caused by single-point force, ensures cleaning uniformity, and reduces the risk of mechanical damage.

[0039] Reference Figures 1 to 4 In some embodiments, the placement mechanism 200 further includes an adjusting screw 250, a second motor 260, and a fixing plate 270. A sliding groove 290 is provided on the placement platform 210. The fixing plate 270 is mounted on the placement platform 210. The adjusting screw 250 is rotatably mounted on the placement platform 210 and the fixing plate 270. One of the placement frames 220 in a set is slidably disposed within the sliding groove 290 and threadedly connected to the adjusting screw 250. The second motor 260 is fixedly mounted on the fixing plate 270 and is drively connected to the adjusting screw 250. The second motor 260 drives the adjusting screw 250 to rotate, and the adjusting screw 250 drives the placement frame 220 to slide, allowing for precise adjustment of the spacing between the two sets of placement frames 220 and flexible adaptation to printing rollers of different lengths. The second motor 260 enables automated adjustment, reducing manual measurement operations and improving equipment versatility and roller changing efficiency.

[0040] Reference Figure 5 In some embodiments, the placement mechanism 200 further includes an abutment ball 280, which is rotatably mounted on the placement frame 220. The abutment ball 280 forms a flexible limit on the end face of the printing roller, allowing the roller to rotate freely while limiting its axial displacement, avoiding roller detachment or collision damage caused by vibration during cleaning, and especially protecting the surface of the rubber roller from hard friction scratches.

[0041] Reference Figure 1 In some embodiments, both the placement platform 210 and the workbench 100 are provided with water guide channels 400, and a collection box is provided at the lower end of the workbench 100. The water guide channels 400 of the workbench 100 and the placement platform 210 are designed to direct the cleaning waste liquid, including ink, chemical solvents, etc., to the collection box to prevent pollution of the workshop environment; at the same time, they keep the operating area dry, avoid the risk of personnel slipping, and comply with industrial safety and environmental protection standards.

[0042] Reference Figure 5In some embodiments, the cleaning mechanism 300 further includes a cleaning brush 330, a lifting platform 340, a lifting cylinder 350, and a third motor 360. The lifting cylinder 350 is fixedly mounted on the upper end of the cleaning frame 320, the lifting platform 340 is fixedly mounted on the piston rod of the lifting cylinder 350, multiple cleaning brushes 330 are rotatably mounted on the lifting platform 340, and the third motor 360 is fixedly mounted on the lifting platform 340. The third motor 360 is drively connected to the cleaning brushes 330. The cleaning brushes 330 can efficiently remove the crystalline layer and stubborn ink residue from the surface of the ink roller; the lifting cylinder 350 precisely controls the downward pressure of the brush head to avoid excessive pressure from the hard brush, which could damage the roller surface; the third motor 360 drives the brush head to rotate, achieving a combined mechanical and hydraulic cleaning effect, significantly improving the removal effect of the calcified layer.

[0043] Reference Figure 5 In some embodiments, the cleaning mechanism 300 further includes a distance sensor 370, which is mounted on the lifting platform 340 and electrically connected to the lifting cylinder 350. The distance sensor 370 monitors the gap between the cleaning brush 330 and the roller surface in real time, and adjusts it for printing rollers of different diameters. It also dynamically adjusts the pressure in conjunction with the lifting cylinder 350 to ensure that rollers of different diameters receive a constant and safe cleaning force, preventing excessive pressure from accelerating the aging of the printing rollers.

[0044] Reference Figures 1 to 5 In some embodiments, the cleaning mechanism 300 further includes a drying assembly 380, which includes an air duct 381, a nozzle 382, ​​and a dryer 383. The dryer 383 is fixedly mounted on the cleaning frame 320. Multiple air ducts 381 are provided and installed within the cleaning frame 320. Multiple nozzles 382 are mounted on the air ducts 381, and the air inlet of the air duct 381 communicates with the air outlet of the dryer 383. The dryer 383, in conjunction with the nozzles 382, ​​sprays hot air onto the cleaned roller surface to accelerate moisture evaporation and prevent residual water stains from mixing with ink to form new dirt. Especially for highly absorbent rubber rollers, considering their soft characteristics, the drying temperature and airflow can be appropriately reduced, and a slow drying method can be used. Timely drying can prevent mold growth in the micropores and extend the service life.

[0045] Reference Figures 2 to 5In some embodiments, the cleaning assembly 310 further includes a water pump 313 and a water tank 314. The water pump 313 is fixedly mounted on the cleaning rack 320, and the water tank 314 is fixedly mounted on the workbench 100. The inlet of the water pump 313 is connected to the water tank 314, and the outlet of the water pump 313 is connected to the inlet of the cleaning pipe 311. The water pump 313 draws cleaning fluid (which can be premixed with a special solvent) from the water tank 314, providing a stable water flow pressure to ensure uniform spray coverage. The closed water tank design supports the addition of customized cleaning agents for ink rollers (strong solvent) or rubber rollers (weak alkaline solvent), achieving precise adaptation for chemical cleaning. For rubber rollers and other soft rollers, the water pressure can be reduced by the water pump 313 for gentle rinsing; while for metal rollers such as ink rollers and high-strength printing rollers, the water pressure can be appropriately increased to enhance cleaning power.

[0046] Reference Figure 1 In some embodiments, the worktable 100 is further provided with a moving mechanism 500, which includes a fourth motor 510 and a moving screw 520. The fourth motor 510 is fixedly mounted on the worktable 100, and the moving screw 520 is rotatably mounted on the worktable 100. The moving screw 520 is drivenly connected to the fourth motor 510. A moving block 530 is fixedly mounted on the bottom of the placement platform 210, and the moving screw 520 is threadedly connected to the moving block 530. Through the cooperation of the moving screw 520 and the fourth motor 510, the placement platform 210 is driven to move directionally and horizontally along the worktable 100, so that the printing roller can be automatically moved into or out of the cleaning area. This avoids the risk of damage caused by manually handling heavy printing rollers, especially metal ink rollers, and reduces collision damage to the roller surface. It provides basic displacement function for the automation of the printing roller "cleaning-drying-unloading" production line and reduces the cost of manual intervention.

[0047] The implementation principle of a cleaning component for printing equipment according to this utility model embodiment is as follows:

[0048] The cleaning component achieves automatic rotation and rinsing of the printing rollers through the cooperation of the drive roller 240 and the first motor 230. The design of multiple sets of dual drive rollers 240 improves the stability of batch processing. The adjusting screw 250 and sliding groove 290 adapt to rollers of different lengths, and the abutment ball 280 prevents axial movement. The water guide trough 400 and collection box realize the environmentally friendly recycling of wastewater, while the lifting cleaning brush 330 accurately removes the crystal layer of the rubber roller under the control of the distance sensor 370. The drying component 380 accelerates the evaporation of moisture on the roller surface to prevent secondary pollution. With the help of the water pump 313 and the water storage tank 314, it supports customized cleaning agent circulation supply. It solves the industry pain points of incomplete cleaning, large damage and low efficiency of printing rollers, significantly extends the life of the roller and reduces maintenance costs, and makes it more convenient for workers to clean the printing rollers.

[0049] The above are all preferred embodiments of this utility model, and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape and principle of this utility model should be included within the scope of protection of this utility model.
