Description

Technical Field

[0001] This application relates to the field of electrode production equipment technology, and in particular to scraper devices and coating equipment. Background Technology

[0002] In gravure roller coating equipment, the two ends of the gravure roller are typically mounted on bearings, and the surface of the gravure roller is partially immersed in a feed tray. Driving the gravure roller to rotate carries the coating liquid from the feed tray onto the substrate. The coating liquid first passes through a doctor blade assembly to scrape off a measured amount of the coating liquid carried by the gravure roller, and then the substrate, moving in the same direction as or in the opposite direction to the gravure roller, carries away the coating liquid from the gravure roller, achieving uniform coating of the substrate.

[0003] In related technologies, the doctor blade assembly includes a horizontal rotating shaft, a doctor blade, and a swing assembly. The doctor blade is fixed on the horizontal rotating shaft and can rotate with the horizontal rotating shaft. The swing assembly connects the horizontal rotating shaft and the doctor blade and drives the doctor blade to swing, so as to adjust the angle of the doctor blade relative to the gravure roller.

[0004] However, since both the scraper and the oscillating assembly are connected to the horizontal rotation axis, the oscillating assembly will cause its oscillation force application point to change during the rotation of the scraper, resulting in uneven force on the scraper and affecting the scraping effect.

[0045] Embodiments of this application will now be described in more detail with reference to the accompanying drawings. While embodiments of this application are shown in the drawings, it should be understood that this application may be implemented in various forms and should not be limited to the embodiments set forth herein.

Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0049] In related technologies, the doctor blade assembly includes a horizontal rotating shaft, a doctor blade, and a swing assembly. The doctor blade is fixed on the horizontal rotating shaft and can rotate with the horizontal rotating shaft. The swing assembly connects the horizontal rotating shaft and the doctor blade and drives the doctor blade to swing, so as to adjust the angle of the doctor blade relative to the gravure roller.

[0050] However, since both the scraper and the oscillating assembly are connected to the horizontal rotation axis, the oscillating assembly will cause its oscillation force application point to change during the rotation of the scraper, resulting in uneven force on the scraper and affecting the scraping effect.

[0051] To address the aforementioned issues, this application provides a scraper device that can be equipped with a swing mechanism to drive the scraper assembly to swing independently. During the rotation and lifting motion of the scraper assembly, the swing force application point of the swing mechanism remains unchanged, ensuring that the scraper is subjected to uniform and stable force and does not affect the scraping effect.

[0052] The technical solutions of the embodiments of this application are described in detail below with reference to the accompanying drawings.

[0053] See Figures 1 to 3 This application provides a scraper device, including a lifting mechanism 1, a rotating mechanism 2, a scraper assembly 3, and a swing mechanism 4. The lifting mechanism 1 includes a lifting seat 10 and a lifting drive assembly 11. The lifting drive assembly 11 is connected to the lifting seat 10 and is used to drive the lifting seat 10 to perform lifting movements. The rotating mechanism 2 includes a rotating shaft 20 rotatably mounted on the lifting seat 10. The scraper assembly 3 includes a scraper seat 30 arranged along the axial direction of the rotating shaft 20 and used to mount a scraper 7, and a connecting sleeve 31 disposed on the scraper seat 30. The end of the connecting sleeve 31 away from the scraper seat 30 is sleeved on the rotating shaft 20 and can drive the scraper seat 30 to rotate under the action of the rotating shaft 20. The swing mechanism 4 is connected to the scraper seat 30 and is used to drive the scraper seat 30 to swing.

[0054] In this embodiment, the lifting direction of the lifting seat 10 can be... Figure 1 In the Z direction, the rotating shaft 20 can rotate around its own axis, and the swing mechanism 4 can drive the scraper seat 30 to swing in the plane in the Z direction.

[0055] In this embodiment, a rotating shaft 20 is installed on the lifting seat 10, and a connecting sleeve 31 is sleeved on the rotating shaft 20. The connecting sleeve 31 is connected to the scraper seat 30, and the scraper seat 30 is connected to the swing mechanism 4. When the lifting drive assembly 11 drives the lifting seat 10 to move up and down, the lifting seat 10 can drive the rotating mechanism 2, the scraper assembly 3, and the swing mechanism 4 to move up and down together. When the rotating shaft 20 rotates, it can drive the scraper assembly 3 and the swing mechanism 4 to rotate together. The swing mechanism 4 drives the scraper seat 30 to swing independently, and is not affected by the rotation and lifting of the scraper seat 30. When the scraper seat 30 is rotating and moving up and down, the swing force applied by the swing mechanism 4 to the scraper seat 30 remains unchanged, so that the scraper 7 is subjected to uniform and stable force and does not affect the scraping effect.

[0056] As an optional embodiment, see Figure 4 The scraper holder 30 includes a mounting plate 300 that is axially arranged along the rotation axis 20 and connected to the swing mechanism 4, and a pressure plate 301 that is located at the end of the mounting plate 300 away from the swing mechanism 4. A clamping space for clamping the scraper 7 is formed between the pressure plate 301 and the mounting plate 300.

[0057] In this embodiment, the scraper holder 30 includes a mounting plate 300 and a pressure plate 301, which increases the load-bearing capacity of the scraper and prevents the scraper holder 30 from bending and deforming after long-term use, thus affecting the scraping effect of the scraper. Furthermore, the scraper holder 30 formed by the combination of the mounting plate 300 and the pressure plate 301 allows for stable fixation of both the upper and lower sides of the scraper, and the angle of the scraper holder 30 can be adjusted via the rotating shaft 20, facilitating the replacement of the scraper 7.

[0058] As an optional embodiment, the scraper device further includes a vertical adjustment mechanism 5, which is connected to the scraper seat 30 and is used to drive the scraper seat 30 to slide on the connecting sleeve 31 in an axial direction perpendicular to the rotation axis 20.

[0059] In this embodiment, the axial direction perpendicular to the rotation axis 20 can be... Figure 1 The distance between the scraper 7 mounted on the scraper seat 30 and the gravure roller 90 in the Y direction can be adjusted by driving the scraper seat 30 to slide on the connecting sleeve 31 in an axial direction perpendicular to the rotation axis 20 through the vertical adjustment mechanism 5.

[0060] In a preferred embodiment, the vertical adjustment mechanism 5 includes a slide block 50, a sliding block 51, and a sliding drive rod 52. The slide block 50 is disposed on the connecting sleeve 31 perpendicular to the axial direction of the rotation shaft 20; the sliding block 51 is connected to the scraper seat 30 and slides on the slide block 50; one end of the sliding drive rod 52 is connected to the slide block 50, and the other end is connected to the sliding block 51, and is used to drive the sliding block 51 to slide on the connecting sleeve 31.

[0061] In this embodiment, by placing the slide block 50 on the connecting sleeve 31, the movement and rotation of the scraper holder 30 in the Y direction can be performed independently without interference. A handwheel can be provided at the end of the sliding drive rod 52 away from the sliding block 51. By rotating the handwheel, the sliding drive rod 52 pushes the sliding block 51 to slide on the slide block 50, thereby adjusting the scraper 7 mounted on the scraper holder 30 to move closer to or further away from the gravure roller 90 in the Y direction.

[0062] In this embodiment, the sliding drive rod 52 can be a lead screw, and the sliding drive rod 52 is screwed to the sliding block 51.

[0063] As an optional embodiment, the scraper device further includes a horizontal adjustment mechanism 6, which is connected to the rotating shaft 20 and is used to drive the rotating shaft 20 to move along its axial direction.

[0064] In this embodiment, the axial direction along the rotation axis 20 can be... Figure 1 The distance between the scraper 7 mounted on the scraper holder 30 and the gravure roller 90 in the X direction is adjusted by driving the rotating shaft 20 to move along the X direction via the horizontal adjustment mechanism 6.

[0065] In a preferred embodiment, the horizontal adjustment mechanism 6 includes a horizontal drive 60 and an eccentric shaft 61.

[0066] The horizontal drive 60 is connected to the lifting seat 10; one end of the eccentric shaft 61 is connected to the horizontal drive 60, and the other end is pivotally connected to the rotating shaft 20 in an axial direction perpendicular to the rotating shaft 20, and is used to drive the rotating shaft 20 to move in its axial direction.

[0067] In this embodiment, the horizontal driver 60 can be a motor cam structure. The eccentric shaft 61 is pivotally connected to the rotating shaft 20 via the cam, and the axial direction of the eccentric shaft 61 is perpendicular to the axial direction of the rotating shaft 20. The motor drives the eccentric shaft 61 to perform eccentric rotational motion, and the cam drives the rotating shaft 20 to perform reciprocating motion in the X direction. When vertical lines are generated during production, the cam structure of the motor can be used to make the scraper 7 on the scraper holder 30 reciprocate in the X direction to rub against the gravure roller 90, thereby improving the vertical line phenomenon. This eliminates the need to replace the scraper 7, improving the service life of the scraper 7 and the product quality.

[0068] It should be noted that the horizontal actuator 60 can also be replaced by other structures, such as a pneumatic cylinder or a hydraulic cylinder.

[0069] In a preferred embodiment, the rotating mechanism 2 further includes a rotating drive assembly 21, which includes a guide seat 210 and a rotating driver 211. The guide seat 210 is disposed on one side of the lifting seat 10 along the axial direction of the rotating shaft 20. The rotating driver 211 is slidably disposed on the guide seat 210 and is connected to the rotating shaft 20, and is used to drive the rotating shaft 20 to rotate. The rotating driver 211 can move on the guide seat 210 along the axial direction of the rotating shaft 20 under the action of the horizontal adjustment mechanism 6.

[0070] In this embodiment, the rotary drive assembly 21 is installed on one side of the lifting seat 10 and can move up and down along the Z direction with the lifting seat 10. Simultaneously, the rotary driver 211 in the rotary drive assembly 21 can drive the rotary shaft 20 to rotate, and the rotary driver 211 can also reciprocate along the X direction on the guide seat 210 with the rotary shaft 20. This avoids the rotary driver 211 from affecting the rotary shaft 20's rotational movement when the rotary shaft 20 moves along the X direction.

[0071] In this embodiment, the rotary driver 211 and the rotary shaft 20 can be a combination of a motor and a lead screw, or a combination of a cylinder / hydraulic cylinder and a piston rod.

[0072] As an optional embodiment, the lifting drive assembly 11 includes a lifting drive rod 111 and a lifting driver 110. The lifting drive rod 111 is disposed in the lifting seat 10 perpendicular to the axial direction of the rotation shaft 20. The lifting driver 110 is disposed on the lifting seat 10, and the drive shaft of the lifting driver 110 is perpendicularly connected to the lifting drive rod 111 and is used to drive the lifting seat 10 to move up and down along the axial direction of the lifting drive rod 111.

[0073] In this embodiment, the lifting drive rod 111 can be fixed, for example, it can be fixed to the frame 8 of the coating equipment by a fixing seat. The drive shaft of the lifting driver 110 is perpendicularly connected to the lifting drive rod 111 and is used to drive the lifting drive rod 111 to move in the Z direction. Since the lifting drive rod 111 is fixed, it can drive the lifting seat 10 to move in the Z direction.

[0074] In this embodiment, the lifting driver 110 and the lifting drive rod 111 can be a combination of a motor and a lead screw, or a combination of a cylinder / hydraulic cylinder and a piston rod.

[0075] As an optional embodiment, the scraper device includes at least two lifting mechanisms 1, which are spaced apart on the rotating shaft 20, and a transmission shaft 12 is connected between the lifting drive rods 111 of the at least two lifting mechanisms 1. The transmission shaft 12 is used to drive the lifting seats 10 of the at least two lifting mechanisms 1 to move up and down synchronously.

[0076] In this embodiment, lifting mechanisms 1 are respectively provided at both ends of the rotating shaft 20. The lifting seats 10 of the two lifting mechanisms 1 are synchronously lifted and lowered by the transmission shaft 12 connected between the two lifting mechanisms 1, so as to ensure the stability of the lifting and lowering movement and avoid deviation due to unbalanced lifting and lowering at both ends of the scraper.

[0077] The lifting drive 110 can be driven by a handwheel, which in turn rotates the drive shaft of the lifting drive 110, thereby causing the lifting drive rod 111 to move along the Z direction. Furthermore, the two lifting mechanisms 1 can share a single lifting drive 110. One end of the transmission shaft 12 is connected to the lifting drive 110, and the other end is connected to the lifting seat 10 of the other lifting mechanism 1. The lifting seats 10 of the two lifting mechanisms 1 can move synchronously by cooperating with one lifting drive 110 and one transmission shaft 12.

[0078] As an optional embodiment, the swing mechanism 4 includes a mounting shaft 40, a swing driver 41, and a swing drive rod 42. The mounting shaft 40 is disposed on the scraper seat 30 along the axial direction of the rotation shaft 20. One end of the swing driver 41 is rotatably connected to the scraper seat 30. One end of the swing drive rod 42 is connected to the end of the swing driver 41 away from the scraper seat 30, and the other end is rotatably connected to the mounting shaft 40, and is used to drive the scraper seat 30 to rotate around the mounting shaft 40 under the driving action of the swing driver 41.

[0079] In this embodiment, the doctor blade holder 30 can be rotated by the rotating shaft 20 to adjust the large angle between the doctor blade 7 on the doctor blade holder 30 and the gravure roller 90; then the doctor blade holder 30 can be driven to swing slightly by the swing mechanism 4 to precisely adjust the small angle between the doctor blade 7 on the doctor blade holder 30 and the gravure roller 90, so as to avoid missing the doctor blade.

[0080] In this embodiment, the swing driver 41 can be a cylinder or a hydraulic cylinder, and the swing drive rod 42 can be a piston rod; or, the swing driver 41 can be a motor, and the swing drive rod 42 can be a lead screw.

[0081] Corresponding to the aforementioned application function implementation device embodiments, this application also provides a coating device and corresponding embodiments.

[0082] See Figure 5 and Figure 6 This application embodiment also provides a coating device, including a frame 8, a coating device 9 disposed on at least one side of the frame 8, and at least one of the aforementioned scraper devices. The lifting drive assembly 11 of the scraper device is disposed on the frame 8 and is used to drive the lifting seat 10 to move up and down along the extension direction of the frame 8; and the scraping direction of the scraper device is opposite to the rotation direction of the gravure roller 90 of the coating device 9.

[0083] In this embodiment, the two ends of the gravure roller 90 are mounted on the frame 8 via bearings. A portion of the surface of the gravure roller 90 is immersed in a feed tray. Driving the gravure roller 90 to rotate carries the coating liquid from the feed tray to coat the substrate. The coating liquid carried by the gravure roller 90 is first scraped off quantitatively by a scraper device, and then carried away by the substrate moving in the same direction as or in the opposite direction to the gravure roller 90, thus achieving uniform coating of the substrate.

[0084] The scraper device provided in this embodiment operates as follows during scraping:

[0085] Assemble the gravure roller 90 required for the process onto the frame 8 in advance. Start the motor button of the material trough mechanism to raise the material trough from bottom to top into position, then start the button again. The material trough will be automatically filled with paste. Start the gravure roller drive motor and rotate the gravure roller 90 clockwise ( Figure 6 Or rotate the gravure roller 90 degrees counterclockwise ( Figure 5 Start rotating at low speed. Then install the plastic scraper and liner required for the process into the clamping space formed between the pressure plate 301 and the mounting plate 300 and fix them with screws. First, adjust the handwheel of the lifting drive 110 to drive the rotating mechanism 2, the scraper assembly 3 and the swing mechanism 4 to rise in the Z direction, raising the scraper 7 to a suitable position. Then adjust the handwheel connected to the sliding drive rod 52 to move the scraper 7 closer to the gravure roller 90 in the Y direction and adjust it to a suitable position. Then start the rotating drive 211, and the scraper 7 rotates around the rotating shaft 20 and presses against the gravure roller 90. Then adjust the scraper 7 according to the condition of the slurry on the surface of the gravure roller 90. The adjustment methods include the following:

[0086] 1. Based on the overall scraping condition of the gravure roller 90, adjust the handwheel connected to the sliding drive rod 52 to further move the scraper 7 closer to or further away from the gravure roller 90 along the Y direction, and scrape off the excess paste on both sides of the gravure roller 90.

[0087] 2. Observe whether there are any missed areas in the middle of the gravure roller 90. If so, start the swing driver 41 to drive the scraper 7 to swing and scrape off the gravure roller 90 until the missed areas disappear.

[0088] 3. During the production process, when vertical lines appear on the product, start the horizontal driver 60 to drive the scraper 7 to move in the X direction until the vertical lines disappear, then stop the horizontal driver 60.

[0089] As an optional embodiment, the coating equipment includes multiple doctor blade devices located on opposite sides of the frame 8, with the scraping direction of the doctor blade devices on the same side of the frame 8 being opposite to the rotation direction of the gravure roller 90 of the coating device 9.

[0090] Figure 5 The image shows a doctor blade device used for gravure roller positive coating (the gravure roller moves in the same direction as the substrate). Figure 6The image shows a doctor blade device used for reverse coating of a gravure roller (the gravure roller moves in the opposite direction to the substrate).

[0091] The scraper device in this embodiment can be applied to both forward and reverse coating of the gravure roller. During use, the scraping direction of the scraper device located on the same side of the frame 8 is opposite to the rotation direction of the gravure roller 90 of the coating device 9, so that the scraper can quickly and effortlessly scrape the gravure roller 90 through the reverse movement of the gravure roller 90.
