Description

Technical Field

[0001] This utility model relates to the field of cleaning tool technology, specifically to a cleaning device for the transmission roller of an electrode coating roller pressing equipment. Background Technology

[0002] Electrode coating refers to the process of applying electrode slurry to the surface of the current collector during battery production to form complete electrode sheets, including the production of positive and negative electrode sheets. This process typically involves applying a pre-mixed electrode slurry to the surface of the current collector using equipment such as rollers and doctor blades, followed by drying and cutting to obtain complete electrode sheet products. To achieve better continuous production, these processes are often connected in series on a production line, using a series of drive rollers to achieve the transfer, coating, drying, and winding / cutting of the strip-shaped current collector.

[0003] Specifically, taking the simplest unipolar electrode as an example, this type of production line typically has at least one pair of feed rollers and take-up rollers at both ends. The feed rollers are wound with a current collector, such as metal foil. After the feed rollers feed the material, the strip of metal foil is conveyed to the coating station through a series of drive rollers. Electrode slurry is coated on the surface by a doctor blade, and then it is conveyed by the drive rollers to the drying station for drying, forming a strip of electrode sheet. Finally, it is conveyed by the drive rollers to the take-up roller for winding, and then transferred to a specific station to be cut into electrode sheets of a specific size.

[0004] In the aforementioned production processes, especially on the drive rollers after the coating station, the slurry from the electrode sheets easily adheres to the roller surface during transport. This slurry is usually in the form of a paste or, after drying, forms particles that stick to the roller surface. Due to the complexity of the production equipment, these rollers are typically encased in various bases and shafts. Therefore, cleaning these rollers usually requires the use of a long, rod-shaped cleaning device to wipe the surface of the rollers.

[0005] For example, Chinese patent CN201410624945.0 discloses a printing roller cleaner, including a base, a telescopic rod, and a handle. A groove is formed at the bottom of the base, and a cleaning sleeve is fitted into the groove. The bottom of the cleaning sleeve has an opening that matches the shape of the printing roller. One end of the telescopic rod is rotatably connected to the far end of the cleaning sleeve on the base, and the other end of the telescopic rod is rotatably connected to the handle. The rotation direction between the telescopic rod and the base is perpendicular to the rotation direction between the handle and the telescopic rod. Its simple structure allows for timely cleaning of printing roller stains without leaving any hard-to-reach areas, thereby improving the printer's printing accuracy and extending its lifespan.

[0006] However, in practical implementation, the inventors discovered that, to achieve better cleaning efficiency, this type of technical solution typically uses a wiping roller device with a certain width to match the actual length of the roller. By having the wiping roller device, whose width matches the roller length, abut against the roller, wiping the entire length of the roller can be achieved relatively easily. But as the variety of products increases, the length of the roller also changes, which means that traditional, fixed wiping roller devices cannot well adapt to the width requirements of different production lines.

[0008] The specific technical solution is as follows:

[0048] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0049] It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0050] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, but this is not intended to limit the present invention.

[0051] This utility model includes:

[0052] A drive roller cleaning device for an electrode coating roller pressing equipment, such as Figure 1 As shown, it includes a vacuuming device 1 and a cleaning head 2 that are connected to each other;

[0053] Cleaning head 2 is shaped like an open box;

[0054] The suction opening of the cleaning head 2 is provided with a pair of inclined plates 3 facing outward;

[0055] The inclined plate 3 is mounted on the suction opening by rotating a pivot, and the rotation angle can be adjusted to change the width of the cleaning head in the downward direction.

[0056] Specifically, in response to the problem that the fixed-length wiping roller tools in the existing technology cannot be well adapted to the rollers on the production line of different specifications, this solution introduces a pair of inclined plates 3 at the front end of the cleaning head 2 with dust suction function. The inclined plates 3 change the opening and closing angle by rotating, thereby realizing the adjustment of the overall width of the cleaning head 2 in the top view, so as to adapt to rollers of different widths.

[0057] Specifically, in order to achieve a better cleaning effect on the roller, in this embodiment, a dust collection device 1 connected to the cleaning head 2 is provided to remove particulate matter on the roller by adsorption.

[0058] The vacuuming device 1 mainly includes a vacuum cleaner 12, which generates negative pressure through an air pump, fan or other equivalent device, and is connected to the vacuum cleaner connection port of the cleaning head 2 through a conduit.

[0059] The cleaning head 2 is mainly in the shape of a hollow box. The hollow part is connected to the vacuum cleaner 12 to form a negative pressure area, thereby adsorbing and removing particles on the roller.

[0060] To accommodate rollers of different lengths, two inclined plates 3 extend from the front end of the cleaning head 2. The inclined plates 3 are rotatably mounted at the front end of the cleaning head 2, and the overall width of the cleaning head 2 can be changed by adjusting the opening and closing angle of the two inclined plates 3.

[0061] The inclined plate 3 is made of PP hard plastic, which can achieve a relatively effective scraping effect.

[0062] See appendix Figure 1 As shown in the top view, when cleaning the roller, the middle part of the cleaning head 2 points to the middle part of the roller. The negative pressure generated by the middle part of the cleaning head 2 adsorbs the particles on the surface of the roller. Since the length of the middle part of the cleaning head 2 is shorter than the length of the roller, it is necessary to adjust the opening angle of the inclined plate 3 extending from the cleaning head 2 so that the overall length of the cleaning head 2 matches the roller. At this time, the parts of the roller on both sides are scraped by the inclined plate 3 to make the particles detach from the surface of the roller and then be adsorbed into the vacuum cleaner by the negative pressure.

[0063] In one embodiment, such as Figure 1 , 2 As shown, the cleaning head 2 is rectangular.

[0064] The first side opening of the cleaning head 2 forms a suction opening;

[0065] A rotating shaft 21 is provided at both ends of the suction opening along the long axis of the first side;

[0066] Both ends of each rotating shaft 21 are connected to the sidewall of the suction opening along the short axis direction of the first side;

[0067] A fixing hole is provided at a predetermined position in the middle of the inclined plate 3;

[0068] The rotating shaft 2 passes through the fixing hole so that the inclined plate 3 can be rotatably mounted on the cleaning head.

[0069] Specifically, in order to effectively adjust the opening angle of the inclined plate 3, in this embodiment, a suction opening is provided on the first side of the rectangular cleaning head 2 away from the vacuum cleaner connection port. Since the cleaning head 2 is a hollow box shape, the cross-section of the suction opening is also rectangular.

[0070] To achieve a good volume, the cleaning head 2 is a hollow rectangular cube. When placed in a cleaning environment, its two mutually perpendicular surfaces near the roller to be cleaned are the first side and the second side, respectively. The first side is open as a suction opening, while the second side is perpendicular to the first side and connected to other surfaces. Figure 2 In the view, the second side is the bottom side, and the fourth side, which is set opposite to the first side, is provided with a vacuum cleaner connection port.

[0071] When the vacuum cleaner generates negative pressure, an airflow will be formed inside the cleaning head 2, flowing from the first side to the fourth side.

[0072] For the suction opening, a rotating shaft 21 is provided at both ends of the long axis direction of the first side. The two ends of each rotating shaft 21 are arranged along the short axis direction of the first side and are connected to the two side walls of the suction opening, namely the second side and the third side.

[0073] Accordingly, a fixing hole is provided at a predetermined position in the middle of the inclined plate 3, and the rotating shaft 2 passes through the fixing hole so that the inclined plate 3 can be rotatably mounted on the cleaning head.

[0074] Generally, the position of the fixing hole will be offset slightly towards the cleaning head 2 relative to the middle position of the inclined plate 3, so that the inclined plate 3 has a longer extension.

[0075] The fixing hole can be a through hole that passes through the inclined plate 3. In this embodiment, the rotating shaft is a rod-shaped component of the whole length. The inclined plate 3 is sleeved on the rotating shaft through the fixing hole and rotates around the rotating shaft.

[0076] In some cases, the fixing holes are formed on both sides of the inclined plate 3. In this case, the rotating shaft is a segmented structure, which is inserted into the fixing holes at both ends, so that the inclined plate 3 is fitted onto the rotating shaft through the fixing holes and rotates around the rotating shaft.

[0077] In one embodiment, the cleaning head 2 further includes a transmission rod 22;

[0078] Inclined plate 3 includes a first inclined plate 31 and a second inclined plate 32;

[0079] The first end of the transmission rod 22 is rotatably mounted on the first rotation mounting point 311 on the transmission side of the first inclined plate 31;

[0080] The second end of the transmission rod 22 is rotatably mounted on the second rotation mounting point 312 on the transmission side of the second inclined plate 32;

[0081] The first rotating mounting point 311 and the second rotating mounting point 312 are located on the inner and outer sides of the line connecting the rotating shafts 21, respectively.

[0082] The transmission side is the upper or lower side of the first and second inclined plates.

[0083] Specifically, in order to make it easier to adjust the opening and closing angle of the two inclined plates 3 on the cleaning head 2, a transmission rod 22 is provided in this embodiment to drive the inclined plates 3 through the lever principle, thereby changing the opening and closing angle.

[0084] In one embodiment, such as Figure 3 As shown, the inclined plate 3 on the right side in the top view is the first inclined plate 31, and the inclined plate 3 on the left side is the second inclined plate 32.

[0085] For the first inclined plate 31, the first rotating mounting point 311 is located on the transmission side of the first inclined plate 31, which is closer to the cleaning head 2 than the rotating shaft 21.

[0086] This position is rotatably connected to the first end of the transmission rod 22. When the transmission rod 22 provides a thrust that is generally pointing to the right, the first rotating mounting point 311 will transmit the thrust, thereby causing the first inclined plate to rotate counterclockwise along the rotating shaft 21 in the top view, thereby reducing the opening and closing angle.

[0087] When the transmission rod 22 provides a pulling force that is generally directed to the left, the first rotating mounting point 311 will transmit the thrust, thereby causing the first inclined plate to rotate clockwise along the rotating shaft 21 in the top view, thereby increasing the opening and closing angle;

[0088] Regarding the second inclined plate 32, the second rotating mounting point 321 is located on the transmission side of the second inclined plate 32, which is further away from the cleaning head 2 relative to the rotating shaft 21.

[0089] The first rotating mounting point 311 and the second rotating mounting point 321 are always at the same height.

[0090] This position is rotatably connected to the first end of the transmission rod 22. When the transmission rod 22 provides a thrust that is generally pointing to the right, the second rotation mounting point 321 will transmit the thrust, thereby causing the second inclined plate 32 to rotate clockwise along the rotating shaft 21 in the top view, thereby reducing the opening and closing angle.

[0091] When the transmission rod 22 provides a thrust that is generally pointing to the left and close to the inside of the cleaning head, the second rotating mounting point 321 transmits the thrust, thereby causing the second inclined plate 32 to rotate counterclockwise along the rotating shaft 21 in the top view, thus increasing the opening and closing angle.

[0092] By pushing and pulling the transmission rod 22, the opening and closing angles of the two inclined plates 3 can be quickly adjusted.

[0093] Among them, in relation to Figure 2 From the perspective shown, after the inclined plate 3 is installed into the suction opening, it is distributed in the vertical direction, so the side located at the top is the upper side, and the above-mentioned transmission structure is all set on the upper side.

[0094] In one embodiment, such as Figure 4 As shown, at least two pressure strip mounting holes are distributed on the lower side of the inclined plate 3;

[0095] Pressure strip 33 is fixed to the pressure strip mounting hole by bolts;

[0096] The pressure strip 33 is a long strip that matches the side of the inclined plate 3;

[0097] The pressure strip 33 is used to clamp the cleaning cloth on the lower side of the inclined plate 3.

[0098] Specifically, in order to achieve a better cleaning effect on the paste-like slurry adhering to the roller, this embodiment also includes a solution of attaching a cleaning cloth to the bottom surface of the inclined plate 3 to remove such contaminants by wiping.

[0099] Specifically, at least two pressure strip mounting holes are distributed on the lower side of the inclined plate 3. When wiping dry particles, the pressure strip 33 is not installed at this position so that the lower side of the inclined plate 3 can scrape the roller.

[0100] When it is necessary to wipe off paste-like slurry, place a long strip of cleaning cloth on the pressure strip, and then fix the cleaning cloth by screwing the pressure strip into the mounting hole of the pressure strip with bolts.

[0101] For example, the cleaning cloth is long and can be first overlapped on the pressure strip 33. Then the pressure strip 33 is screwed onto the pressure strip mounting hole by bolts. At this time, the cleaning cloth is sandwiched between the pressure strip 33 and the lower side of the inclined plate 3. The cleaning cloth has an additional extension that will naturally fall off the part that is not sandwiched by the side, for wiping contaminants.

[0102] In one embodiment, the vacuuming device 1 is connected to the subsequent vacuum cleaner 12 via a connecting pipe 11;

[0103] The connecting pipe 11 includes a rigid pipe 111 and a flexible pipe 112 that are connected to each other;

[0104] The other end of the rigid tube 111 is connected to the cleaning head 2;

[0105] The other end of the hose 112 is connected to the vacuum cleaner 12.

[0106] Specifically, in order to achieve better control, in this embodiment, a connecting pipe 11 of interconnected rigid pipe 111 and flexible pipe 112 is introduced into the vacuuming device 1 as a connecting component between the cleaning head 2 and the vacuum cleaner 12.

[0107] The other end of the rigid tube 111 is connected to the cleaning head 2, which is used as a handle to facilitate changing the position of the cleaning head 2 for cleaning.

[0108] Meanwhile, to adapt to different production equipment, the rigid pipe also includes at least two expansion joints. The expansion joints are sleeve-shaped, with the smaller pipe inserted into the larger pipe. The length of the rigid pipe 111 is changed by changing the insertion depth. The expansion joints are fixed by friction or thread locking.

[0109] To facilitate adjustment of the cleaning angle, a rotating device is provided at the front end of the rigid tube 111 in this embodiment to connect the cleaning head. The rotating device includes a recessed spherical base located on the cleaning head and a ball head located on the rigid tube 111. The ball head is inserted into the spherical base to achieve a rotatable connection. An opening is provided between the ball head and the spherical base to allow airflow to pass through.

[0110] Hose 112 is a corrugated or rubber hose, which facilitates movement and provides a longer travel distance.

[0111] A production system employs the aforementioned drive roller cleaning device.

[0112] The above are merely preferred embodiments of the present utility model and are not intended to limit the implementation methods and protection scope of the present utility model. Those skilled in the art should realize that any equivalent substitutions and obvious changes made based on the description and illustrations of the present utility model should be included within the protection scope of the present utility model.
