Description

Technical Field

[0001] This application relates to the technical field of equipment cleaning, and in particular to a rubber roller impurity cleaning device. Background Technology

[0002] The rubber roller is one of the core components of a offset printing press and a key part of the printing unit. The roller surface is covered with a special rubber blanket, which is elastic, pressure-resistant, and has ink absorption properties, enabling it to accurately transfer images and text and adapt to different paper surfaces.

[0003] In existing offset printing presses, low-grade paper fibers are loose and easily shed paper dust and other impurities during use. These impurities adhere to the blanket, and when the accumulation is excessive, they hinder the normal transfer of ink, thus affecting the print quality. The current solution is to stop the printing press and clean the impurities from the blanket, but this affects the overall printing efficiency and needs improvement. Utility Model Content

[0004] The purpose of this application is to provide a rubber roller impurity cleaning device to reduce the amount of impurities adhering to the rubber blanket without stopping the printing press.

[0005] The rubber roller impurity cleaning device provided in this application adopts the following technical solution: it includes a guide rail for connecting to a printing press and a slider slidably connected to the guide rail. The slider is provided with a groove for sliding cooperation with the guide rail. The slider is connected to a connecting plate, and one end of the connecting plate is connected to a scraper head for contacting the rubber blanket.

[0006] By adopting the above technical solution, when it is necessary to clean impurities on the blanket, the slider is moved. The slider slides along the length of the guide rail, and the connecting plate and the scraper head move with the slider, so that the scraper head contacts the outer peripheral surface of the blanket. The blanket rotates around the axis of the cylinder. During the rotation of the blanket, the scraper head scrapes off the impurities attached to the outer peripheral surface of the blanket, avoiding the accumulation of impurities, thereby improving the paper printing quality. Moreover, there is no need to stop the printing press for cleaning, which improves the overall paper printing efficiency.

[0007] Optionally, the scraper head is provided with a contact surface, which is arc-shaped.

[0008] By adopting the above technical solution, the arc-shaped contact surface can form a closer fit with the surface of the rubber blanket, reduce cleaning blind spots, ensure that impurities are completely scraped off, and improve the impurity removal effect.

[0009] Optionally, the scraper head is provided with a positioning block, the connecting plate is provided with a positioning groove, the positioning groove is used to cooperate with the positioning block, and the connecting plate is connected with a locking member, the locking member is used to fix the positioning block on the connecting plate.

[0010] By adopting the above technical solution, the scraper head is detachably connected to the connecting plate via a locking component, facilitating scraper head replacement. The positioning block engages with the positioning groove, with its outer surface fitting against the inner wall of the groove. This engagement of the positioning block and groove positions the scraper head during installation, thereby improving the efficiency of fixing the scraper head to the connecting plate via the locking component.

[0011] Optionally, the scraper head is a rubber head.

[0012] By adopting the above technical solution, the scraper head is made of rubber. The rubber is soft and can reduce wear on the rubber blanket when cleaning impurities, thus extending the service life of the rubber blanket.

[0013] Optionally, the connecting plate includes a fixed plate connected to the slider and a sliding plate that slides with the fixed plate. The scraper head is connected to the sliding plate, and an elastic element is connected between the sliding plate and the fixed plate. One end of the elastic element is connected to the sliding plate, and the other end is connected to the fixed plate.

[0014] By adopting the above technical solution, when the outer surface of the rubber blanket is attached with protrusions, the protrusions abut against the scraper head and drive the sliding plate to slide towards the fixed plate. The elastic element is compressed and produces elastic deformation and maintains the tendency of elastic reset, thus avoiding damage to the cleaning device. When the protrusions separate from the scraper head, the elastic element resets elastically, and the elastic element forces the scraper head to reset, so that the scraper head continues to scrape off the impurities attached to the outer surface of the rubber blanket.

[0015] Optionally, the sliding plate is connected to a guide rod, and the fixed plate is provided with a guide groove, which is used to slide and cooperate with the guide rod.

[0016] By adopting the above technical solution, when the sliding plate slides, the sliding cooperation between the guide rod and the guide groove guides and limits the sliding of the sliding plate, thereby improving the stability of the sliding plate. The inner wall of the guide groove supports the guide rod, thereby improving the stability of the connection between the sliding plate and the fixed plate.

[0017] Optionally, the sliding plate is connected to a support block, and the fixed plate is provided with a support groove, which is used to slide and cooperate with the support block.

[0018] By adopting the above technical solution, when the sliding plate slides, the sliding cooperation between the support block and the support groove guides and limits the sliding of the sliding plate, thereby improving the stability of the sliding plate. The inner wall of the support groove supports the support block, thereby improving the stability of the connection between the sliding plate and the fixed plate.

[0019] Optionally, the fixing plate is connected to a stop block, the stop block is used to cover the support groove, the stop block is connected to a fastener, and the stop block is connected to the fixing plate through the fastener.

[0020] By adopting the above technical solution, the stop block plays a limiting role in the sliding of the support block, preventing the support block from falling out of the support groove during the sliding process.

[0021] Optionally, the fixing plate is provided with a limiting groove, which is used to cooperate with the stop block.

[0022] By adopting the above technical solution, when installing the stop block, the stop block is inserted into the limiting groove, and the outer surface of the stop block fits against the inner wall of the limiting groove. The cooperation between the limiting groove and the stop block plays a positioning role in the installation of the stop block, thereby improving the efficiency of installing the stop block on the fixed plate.

[0023] Optionally, a hand grip is provided at the end of the connecting plate away from the scraper head.

[0024] By adopting the above technical solution, the hand grip makes it easy for operators to hold the connecting plate and facilitates its movement.

[0025] In summary, this application includes at least one of the following beneficial technical effects:

[0026] 1. When it is necessary to clean impurities on the blanket, move the slider. The slider slides along the length of the guide rail. The connecting plate and the scraper head move with the slider, so that the scraper head contacts the outer circumference of the blanket. The blanket rotates around the axis of the cylinder. During the rotation of the blanket, the scraper head scrapes off the impurities attached to the outer circumference of the blanket, avoiding the accumulation of impurities, thereby improving the paper printing quality. Moreover, there is no need to stop the printing press for cleaning, which improves the overall paper printing efficiency.

[0027] 2. When the outer surface of the rubber blanket is covered with protrusions, the protrusions abut against the scraper head and drive the sliding plate to slide towards the fixed plate. The elastic element is compressed and undergoes elastic deformation and maintains the tendency to elastically return to its original position, thus avoiding damage to the cleaning device. When the protrusions separate from the scraper head, the elastic element returns to its original position, and the elastic element forces the scraper head to return to its original position, so that the scraper head continues to scrape off the impurities attached to the outer surface of the rubber blanket.

[0035] The following is in conjunction with the appendix Figure 1 -Appendix Figure 6 This application will be described in further detail.

[0036] This application discloses a rubber roller impurity cleaning device.

[0037] like Figure 1 As shown, the machine includes a guide rail 1 and a slider 2 slidably connected to the guide rail 1. The guide rail 1 is fixedly connected to the machine door of the printing press. The slider 2 has a groove 21 that slides and engages with the guide rail 1. A roller is rotatably connected to the machine door, and a rubber blanket is fixedly connected to the outer circumference of the roller. A connecting plate 3 is connected to the slider 2, passing through the slider 2 and fixedly connected to it. The moving direction of the slider 2 is perpendicular to the length direction of the connecting plate 3. The machine door has a clearance groove, and the connecting plate 3 slides along the clearance groove.

[0038] Combination Figure 2 and Figure 3As shown, the connecting plate 3 includes a fixed plate 31 fixedly connected to the slider 2 and a sliding plate 32 slidably connected to the fixed plate 31. The fixed plate 31 passes through the slider 2. A handle 311 is provided at the end of the fixed plate 31 away from the sliding plate 32. The handle 311 is integrally formed with the fixed plate 31 and is inclined. The end of the handle 311 away from the fixed plate 31 is higher than the end of the handle 311 near the fixed plate 31. A scraper head 4 is detachably connected to the end of the sliding plate 32 away from the fixed plate 31. The scraper head 4 is a rubber head made of rubber. A positioning block 41 is provided on the side of the scraper head 4 near the sliding plate 32. The positioning block 41 is integrally formed with the scraper head 4. The sliding plate 32 has a positioning groove 321, which cooperates with the positioning block 41. Two locking parts 5 are connected to the sliding plate 32. The locking parts 5 are bolts. The scraper head 4 is fixedly connected to the sliding plate 32 by the two locking parts 5. The lower surface of the scraper head 4 has a contact surface 42, which is arc-shaped. When the grip 311 moves the scraper head 4, the scraper head 4 contacts the outer circumference of the rubber blanket. The roller rotates around its own axis, and the rubber blanket rotates around the axis of the roller. The scraper head 4 scrapes away impurities attached to the outer surface of the rubber blanket, removing impurities without stopping the machine and improving the overall printing efficiency of the paper. After the impurities are cleaned, the scraper head 4 is removed, so that the scraper head 4 is offset from the roller, making it easier to clean the impurities attached to the scraper head 4.

[0039] Combination Figure 4 , Figure 5 and Figure 6As shown, a connecting portion 322 is provided on the side of the sliding plate 32 near the fixed plate 31. The connecting portion 322 is integrally formed with the sliding plate 32. A receiving groove 312 is provided on the side of the fixed plate 31 near the sliding plate 32, and the connecting portion 322 slides within the receiving groove 312. Two guide rods 323 are fixedly connected to the side of the connecting portion 322 near the fixed plate 31. The two guide rods 323 are distributed in parallel. The fixed plate 31 has two guide grooves 313 communicating with the receiving groove 312. The guide grooves 313 correspond one-to-one with the guide rods 323, and the guide rods 323 slide and engage with the guide grooves 313. Each guide rod 323 is fitted with an elastic element 33, which is a spring. One end of the elastic element 33 is fixedly connected to the connecting portion 322, and the other end is fixedly connected to the fixed plate 31. Support blocks 324 are provided on both opposite sides of the connecting part 322. The support blocks 324 are integrally formed with the connecting part 322. The fixing plate 31 has two support grooves 314 communicating with the receiving groove 312. The support grooves 314 correspond one-to-one with the support blocks 324, and the support blocks 324 slide within the support grooves 314. Two stop blocks 6 are detachably connected to the outer surface of the fixing plate 31. The stop blocks 6 are L-shaped and correspond one-to-one with the support grooves 314. The stop blocks 6 cover the support grooves 314 to prevent the support blocks 324 from falling out of the support grooves 314 during sliding. Each stop block 6 is connected to a fixing member 61, which is a bolt. The stop block 6 is fixedly connected to the fixing plate 31 through the fixing member 61. Two limiting grooves 315 are provided on the outer surface of the fixing plate 31. The limiting grooves 315 correspond one-to-one with the stop blocks 6. The stop blocks 6 can be inserted into the limiting grooves 315 to position the stop blocks 6, thereby improving the stability of the stop blocks 6 installed on the fixing plate 31. When the outer periphery of the rubber blanket is covered with protrusions, the protrusions abut against the contact surface 42 and drive the sliding plate 32 to slide towards the fixed plate 31. The elastic element 33 is compressed and maintains the tendency to elastically reset, thus avoiding damage to the cleaning device. When the protrusions separate from the scraper head 4, the elastic element 33 elastically resets, and the elastic element 33 forces the scraper head 4 to reset, so that the scraper head 4 can continue to clean the impurities attached to the rubber blanket.

[0040] The implementation principle of the rubber roller impurity cleaning device in this application embodiment is as follows:

[0041] When it is necessary to clean the impurities attached to the blanket, the operator uses the hand grip 311 to move the fixed plate 31, the sliding plate 32 and the scraper head 4 along the length of the guide rail 1. During the sliding process, the scraper head 4 contacts the rotating blanket and scrapes off the impurities attached to the outer surface of the blanket, avoiding the accumulation of impurities, thereby improving the paper printing quality. Moreover, there is no need to stop the printing press for cleaning, which improves the overall paper printing efficiency.

[0042] The above are all preferred embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
