The various technical features in the creation of the utility model can be combined interchangeably without conflicting with each other.

[0041] The coating machine is the most important core equipment in the front-end processing equipment of lithium batteries. When the coating machine is coating, the micro-gravure roller covered with slurry needs a scraper to remove the excess slurry on the surface. Part of the slurry will be scraped to the end faces of both sides of the roller by the scraper, and the high-speed rotating roller will throw the slurry on the end face and stick it to the equipment wallboard and the wall of the material box, and then dry and form hard lumps. After a period of time, the hard lumps on the wall of the material box fall into the material box and are re-coated on the substrate, resulting in spots and bumps on the substrate, and the coating yield rate is reduced.

[0042] In order to solve the problem in the prior art that the high-speed rotating plate roller will throw the slurry on its end surface onto the equipment wall panel and the wall of the material box to form hard lumps, and the hard lumps fall into the material box and are re-coated on the substrate, causing spot and convex defects on the substrate, the embodiment of the utility model provides a plate roller end surface scraper device and a coater.

[0043] The utility model provides a plate roller end surface scraper device which is installed on the plate plug end surfaces at both ends of the plate roller and is used for scraping off the slurry on the end surfaces of both sides of the plate roller.

[0044] See also Figure 1 , Figure 1 The present invention is a schematic diagram of the installation structure of a scraper device on the end surface of a plate roller proposed in an embodiment of the present invention.

[0045] like Figure 1 As shown, by arranging the scraper device 100 on the end surface of the plate roller 200 on the plate plug 300 on both sides of the plate roller 200, the slurry scraped to the end surfaces of both sides of the plate roller 200 can be scraped off to prevent the slurry from splashing and being thrown onto the equipment wall panel and the wall of the material box to dry and form hard lumps, and the hard lumps fall into the material box and are re-applied to the substrate, causing spot and convex defects on the substrate.

[0046] See also Figures 2 to 3 , Figure 2 This is a schematic diagram of the first angle structure of a scraper device for the end surface of a plate roller proposed in an embodiment of the utility model. Figure 3 This is a second angle structural schematic diagram of a plate roller end scraper device proposed in an embodiment of the utility model.

[0047] like Figures 2 to 3 As shown, a plate roller end surface scraper device 100 proposed in an embodiment of the utility model includes a fixed plate 1 installed on the end surface of a plate plug 300 , an adjustment component 2 fixedly connected to the fixed plate 1 , and a scraper component 3 connected to the adjustment component 2 .

[0048] Among them, the fixed plate 1 is used to install the entire plate roller end surface scraper device 100 on the plate plug 300, and the plate plug 300 is arranged on both sides of the plate roller 200. The fixed plate 1 is used to install the plate roller end surface scraper device 100 on the plate plug 300, which can facilitate the plate roller end surface scraper device 100 to scrape off the slurry on the end surfaces of both sides of the plate roller 200.

[0049] The adjustment component 2 is used to adjust the scraper component 3 against the end face of the plate roller 200, including the distance of the scraper component 3 relative to the end face of the plate roller 200, the abutment force of the scraper component 3 relative to the end face of the plate roller 200, the angle of the scraper component 3 relative to the end face of the plate roller 200, the position of the scraper component 3 relative to the end face of the plate roller 200, etc., so that the scraper component 3 can scrape off the slurry on the end faces of both sides of the plate roller 200.

[0050] The scraper assembly 3 includes a scraper fixing seat 31 and a scraper blade 32. One end of the scraper fixing seat 31 is connected to the adjustment assembly 2, and the other end of the scraper fixing seat 31 is detachably provided with the scraper blade 32. The scraper fixing seat 31 is used to fix the scraper blade 32 on the adjustment assembly 2, and at the same time, the adjustment assembly 2 is convenient to adjust the scraper blade 32 through the scraper fixing seat 31. The scraper blade 32 is used to abut against the end surface of the plate roller 200, and scrape off the slurry on the end surface of the plate roller 200 when the plate roller 200 rotates.

[0051] For further information, see Figure 4 , Figure 4 It is a structural schematic diagram of a fixed plate 1 in a plate roller end scraper device proposed in an embodiment of the utility model.

[0052] like Figure 1 and Figure 4 As shown, in the embodiment of the present invention, the fixing plate 1 includes a first fixing plate 11 and a second fixing plate 12 .

[0053] Wherein, the first fixing plate 11 is fixedly installed on the end face of the plate plug 300. The first fixing plate 11 is a fan ring, and the inner and outer radii of the fan ring are consistent with the inner and outer radii of the plate plug 300. At least one mounting hole is provided on the first fixing plate 11, and a mounting hole is correspondingly provided on the end face of the plate plug. The fasteners pass through the mounting holes on the first fixing plate 11 and the corresponding mounting holes on the plate plug 300 in sequence to fix the first fixing plate 11 on the end face of the plate plug. When the first fixing plate 11 is fixedly installed on the end face of the plate plug 300, the outer ring of the first fixing plate 11 is aligned with the outer ring of the end face of the plate plug 300, and the inner ring of the first fixing plate 11 is aligned with the inner ring of the end face of the plate plug 300. Wherein, the mounting hole can be a threaded hole, and the fastener is a bolt. It can be understood that the mounting hole can also be a through hole, and the fastener is a pin.

[0054] The second fixing plate 12 is an arc-shaped plate, one end of the second fixing plate 12 is vertically connected to the first fixing plate 11, and the other end of the second fixing plate 12 is connected to the adjustment assembly 2. In the embodiment of the utility model, the radius of the second fixing plate 12 is consistent with the inner radius of the first fixing plate 11, the second fixing plate 12 is perpendicular to the inner ring of the first fixing plate 11, and is connected to the first fixing plate 11 at an angle.

[0055] Further, such as Figures 2 to 3 As shown, the adjustment assembly 2 includes a mounting seat 201 , a connecting member 202 and a positioning assembly 203 .

[0056] The mounting seat 201 is fixed to the fixing plate 1 so as to fix the entire adjusting assembly 2 to the fixing plate 1 .

[0057] The connecting member 202 is movably arranged in the mounting seat 201, and one end of the connecting member 202 is connected to the scraper assembly 3. The connecting member 202 is used to connect the scraper assembly 3 and the adjustment assembly 2, and the distance between the mounting seat 201 and the scraper assembly 3 is adjusted along the extension direction of the connecting member 202 to achieve the adjustment of the scraper assembly 3 by the adjustment assembly 2. In the embodiment of the utility model, two connecting members 202 are provided to ensure the connection and adjustment stability between the adjustment assembly 2 and the scraper assembly 3. It can be understood that the number of connecting members 202 can be set according to actual conditions.

[0058] The positioning assembly 203 is connected to the mounting seat 201 , and is used to adjust the distance between the mounting seat 201 and the scraper assembly 3 along the extending direction of the connecting member 202 and fix the position of the scraper assembly 3 to achieve adjustment of the position of the scraper assembly 3 .

[0059] Furthermore, the positioning assembly 203 includes a limiting seat 2031 , a first adjusting bolt 2032 , an adjusting nut 2033 and an elastic member 2034 .

[0060] The limiting seat 2031 is fixedly connected to the end of the connector 202 away from the scraper assembly 3. Specifically, the limiting seat 2031 is provided with through holes for accommodating the connector 202, and the number of through holes and the positions of the through holes on the limiting seat 2031 correspond to the number and positions of the connector 202. A groove communicating with the through hole is provided on one side of the through hole, and the end of the connector 202 away from the scraper assembly 3 is placed in the through hole of the limiting seat 2031, and the top screw fastens the connector 202 to the limiting seat 2031 through the groove on one side of the through hole.

[0061] The first adjusting bolt 2032 passes through the limiting seat 2031 and is movably connected with the mounting seat 201. The adjusting nut 2033 is sleeved on the first adjusting bolt 2032 and is located between the limiting seat 2031 and the mounting seat 201. Specifically, the limiting seat 2031 is provided with a through hole for accommodating the first adjusting bolt 2032 to pass through, and the mounting seat 201 is correspondingly provided with a threaded through hole or a threaded groove for accommodating the first adjusting bolt 2032. The first adjusting bolt 2032 passes through the through hole on the limiting seat 2031 and is placed in the threaded through hole or the threaded groove on the mounting seat 201. The adjusting nut 2033 is sleeved on the first adjusting bolt 2032 and is placed between the limiting seat 2031 and the mounting seat 201. In a normal state, the adjusting nut 2033 is just connected and fitted with the limiting seat 2031. In this state, the distance between the mounting seat 201 and the scraper assembly 3 is the largest, and the distance between the scraper assembly 3 and the end face of the plate roller 200 is the shortest.

[0062] When the first adjusting bolt 2032 is adjusted upward along the direction of the limiting seat 2031 facing away from the mounting seat 201, the adjusting nut 2033 abuts against the limiting seat 2031, so that the limiting seat 2031 moves upward. The limiting seat 2031 drives the connecting member 202 to move upward relative to the mounting seat 201, and the scraper assembly 3 connected to the connecting member 202 moves with the connecting member 202 to shorten the distance between the scraper assembly 3 and the mounting seat 201, thereby increasing the distance between the scraper assembly 3 and the end surface of the plate roller 200.

[0063] When the first adjusting bolt 2032 is adjusted downward along the direction of the limiting seat 2031 toward the mounting seat 201, the force of the adjusting nut 2033 against the limiting seat 2031 gradually decreases, so that the limiting seat 2031 moves downward. The limiting seat 2031 drives the connecting member 202 to move downward relative to the mounting seat 201, and the scraper assembly 3 connected to the connecting member 202 moves with the connecting member 202 to increase the distance between the scraper assembly 3 and the mounting seat 201, thereby reducing the distance between the scraper assembly 3 and the end surface of the plate roller 200.

[0064] The elastic member 2034 is sleeved on the connecting member 202 and is located between the mounting seat 201 and the scraper assembly 3. When the first adjusting bolt 2032 cooperates with the adjusting nut 2033 to shorten the distance between the scraper assembly 3 and the mounting seat 201 to increase the distance between the scraper assembly 3 and the end face of the plate roller 200, the elastic member 2034 is compressed to shrink and deform, and store deformation energy. When the first adjusting bolt 2032 cooperates with the adjusting nut 2033 to increase the distance between the scraper assembly 3 and the mounting seat 201 to shorten the distance between the scraper assembly 3 and the end face of the plate roller 200, the elastic member 2034 is gradually released to convert the deformation energy into thrust, push the scraper assembly 3 away from the mounting seat 201, and give the scraper assembly 3 a force to contact the end face of the plate roller 200 so as to scrape off the slurry on the end face of the plate roller 200. In the embodiment of the utility model, the elastic member 2034 is an adjusting spring. It can be understood that the elastic member can also be a hollow elastic colloid cylinder, etc.

[0065] In some embodiments, the positioning assembly 203 may also be a quick clamp or an adjustment screw.

[0066] Please continue to see Figures 2 to 3 The adjusting component 2 also includes a bearing 204 and an adjusting screw sleeve 205 .

[0067] The adjusting screw sleeve 205 is sleeved on the connecting member 202 and is arranged in the mounting seat 201. Specifically, the mounting seat 201 is provided with a mounting hole corresponding to the adjusting screw sleeve 205, and the mounting hole is provided with a thread. The adjusting screw sleeve 205 is arranged in the mounting hole of the mounting seat 201 through a threaded connection to achieve connection with the mounting seat 201. One end of the adjusting screw sleeve 205 is connected to the bearing 204 to fix the bearing 204 in the mounting seat 201, and the other end of the adjusting screw sleeve 205 is connected to the elastic member 2034 to fix the elastic member 2034 to the mounting seat 201.

[0068] The bearing 204 is sleeved on the connecting member 202 and connected to the adjusting screw sleeve 205. The bearing 204 is used to reduce the friction between the connecting member 202 and the mounting seat 201, so that the connecting member 202 can move more smoothly relative to the mounting seat 201. In the embodiment of the utility model, the bearing 204 is an oil-free sleeve. It can be understood that the bearing 204 can also be a linear bearing, etc.

[0069] See also Figure 2 , Figure 3 , Figure 5 as well as Figure 6 The adjustment assembly 2 also includes an adjustment block 206 disposed between the fixing plate 1 and the mounting seat 201 , and the adjustment block 206 is fixedly connected to the mounting seat 201 .

[0070] The mounting seat 201 is provided with a first arc-shaped through hole 2011, and a first groove 2061 is correspondingly provided on one side of the adjustment block facing the mounting seat 201. The second adjustment bolt 207 passes through the first arc-shaped through hole 2011 and is placed in the first groove 2061 to fix the mounting seat 201 to the adjustment block 206. The first groove 2061 is provided with a thread, and the second adjustment bolt 207 is connected to the first groove 2061 by a thread to fix the mounting seat 201 and the adjustment block 206. The mounting seat 201 can move relative to the adjustment block 206 along the extension direction of the first arc-shaped through hole 2011, and the mounting seat 201 drives the scraper assembly 3 through the connecting member 202 to adjust the angle of the scraper assembly 3. By adjusting the angle of the scraper assembly 3, the ink scraper on the scraper assembly 3 can scrape off the slurry on one side end surface of the plate roller 200 to the maximum extent, thereby improving the efficiency of scraping off the slurry.

[0071] See also Figures 2 to 6 The adjustment component 2 also includes a pin 208 , a flange bearing 209 and a retaining ring 210 .

[0072] The adjusting block 206 is provided with a first through hole 2062, and the mounting seat 201 is correspondingly provided with a second through hole 2012. The pin 208 passes through the flange bearing 209, the first through hole 2062, and the second through hole 2012 in sequence and is fixed to the retaining ring 210 to realize the rotation connection between the adjusting block 206 and the mounting seat 201.

[0073] Specifically, the first arc-shaped through hole 2011 is arranged with the second through hole 2012 as the center, and any point on the first arc-shaped through hole 2011 is at the same distance from the second through hole 2012. The mounting plate 201 can rotate around the pin 208 along the extension direction of the first arc-shaped through hole 2011. The flange bearing 209 is used to reduce the rotation friction when the mounting plate 201 rotates around the pin 208 to make the rotation smoother, and the retaining ring 210 is used to prevent the pin 208 from axially moving when the mounting plate 201 rotates around the pin 208, so that there is a risk of falling off. The pin 208, the flange bearing 209 and the retaining ring 210 are provided to improve the stability of the connection and adjustment between the adjustment block 206 and the mounting seat 201.

[0074] See also Figures 2 to 4 The adjustment assembly 2 also includes an adjustment plate 211 , which is fixedly disposed on the fixing plate 1 , and the adjustment plate 211 is connected to the mounting seat 201 .

[0075] Among them, a second arc-shaped through hole 2111 is arranged on the adjustment plate 211, and at least one third through hole 121 is correspondingly arranged on the fixed plate 1. The third adjustment bolt 212 passes through the second arc-shaped through hole 2111 and the third through hole 121 in sequence and is fixed on the fixed plate 1. The adjustment plate 211 is used to drive the mounting seat 201 to move along the extension direction of the second arc-shaped through hole 2111 to realize the adjustment of the position of the scraper assembly 3.

[0076] In the embodiment of the utility model, the adjustment plate 211 is an arc-shaped piece, and its shape is consistent with the second fixing plate 12. The adjustment plate 211 is vertically fixedly connected with the adjustment block 206 and the adjustment plate 211 and the adjustment block 206 are the same part. The adjustment plate 211 is connected to the mounting seat 201 through the adjustment block 206.

[0077] Among them, the adjustment plate 211 is provided with a second arc-shaped through hole 2111, and the second fixed plate 12 is correspondingly provided with a third through hole 121. The third adjusting bolt 212 passes through the second arc-shaped through hole 2111 and the third through hole 121 in sequence to fix the adjustment plate 211 on the fixed plate 1. The adjustment plate 211 can drive the mounting seat 201 to move along the extension direction of the second arc-shaped through hole 2111, and then drive the scraper assembly 3 to achieve the position adjustment of the scraper assembly 3. By changing the position of the scraper assembly 3 scraping off the slurry on one side of the plate roller 200, it is avoided that the scraped slurry flows to the scraper assembly 3 and then flows back to the end face of one side of the plate roller, thereby improving the efficiency of scraping off the slurry on the end face of the plate roller 200. In the embodiment of the utility model, two second adjusting bolts 212 and two third through holes 121 are symmetrically arranged to improve the stability of the adjustment of the scraper assembly 3. It can be understood that the number of the second adjusting bolts 212 and the third through holes 121 is set according to the actual situation.

In the embodiment of the utility model, the first fixing member is a top screw, and the connecting member 202 is pressed tightly into the second groove 3121 through the top screw to achieve a fixed connection between the connecting member 202 and the scraper lower pressing plate 31.

[0083] See also Figure 8 , Figure 8 The utility model is a schematic structural diagram of a scraper upper pressure plate in a roller end scraper device proposed in an embodiment of the utility model.

[0084] like Figure 8 As shown, the scraper upper pressing plate 311 includes a first upper pressing plate 3111 and a second upper pressing plate 3112. The first upper pressing plate 3111 is provided with a mounting hole, and the scraper lower pressing plate 312 is correspondingly provided with a mounting hole.

The first upper pressing plate 3111 is connected to the second upper pressing plate 3112 at a certain angle, and correspondingly, a step is provided at the corresponding position of the scraper lower pressing plate 312. When the scraper upper pressing plate 311 is connected to the scraper lower pressing plate 312, the connection position of the first upper pressing plate 3111 and the second upper pressing plate 3112 just corresponds to the step of the scraper lower pressing plate 312, and a certain space is formed between the scraper upper pressing plate 311 and the scraper lower pressing plate 312 to facilitate the installation of the ink scraper 32. In addition, a mounting hole is provided on the second upper pressure plate 3112 , and bolts are passed through the mounting hole to hold the ink scraper 32 against the scraper lower pressure plate 312 , so as to achieve a detachable connection between the ink scraper 32 and the scraper upper pressure plate 311 and the scraper lower pressure plate 312 .

[0085] In addition, an embodiment of the utility model also proposes a coating machine, which is provided with a plate roller end surface scraper device as described in any of the above embodiments.

[0086] In summary, the scraper device for the end surface of the plate roller proposed in the embodiment of the utility model has at least the following beneficial effects compared with the prior art:

[0087] Firstly, a scraper device for the end face of the plate roller proposed in an embodiment of the utility model is arranged on the plate plugs at both ends of the plate roller, and is used to scrape the slurry on the end faces of both sides of the plate roller into the material box at the lower end of the plate roller, thereby solving the problem that the slurry on the end faces of both sides of the plate roller splashes onto the equipment wall panels and the walls of the material box to form hard lumps and fall into the material box, and the hard lumps of slurry are re-applied to the substrate, resulting in a decrease in the coating yield.

[0088] Secondly, a scraper device for the end face of a plate roller proposed in an embodiment of the utility model is provided with an adjustment component, which adjusts the distance of the scraper component relative to the end face of one side of the plate roller through a first adjustment bolt and an adjustment nut, so that the scraper component can scrape the slurry on the end face of one side of the plate roller.

[0089] Again, the adjustment assembly can adjust the angle of the scraper assembly through the first arc-shaped through hole, the adjustment block and the second adjustment bolt on the mounting plate. By adjusting the angle of the scraper assembly, the scraper on the scraper assembly can scrape off the slurry on one end surface of the plate roller over a large area, thereby improving the efficiency of scraping off the slurry.

[0090] In addition, the adjustment component can adjust the position of the scraper assembly through the second arc-shaped through hole on the adjustment plate and the third adjustment bolt. By adjusting the position of the scraper assembly, the position of the scraper assembly on the end surface of one side of the plate roller is changed to scrape the slurry off, so as to avoid the scraped slurry flowing onto the scraper assembly and then flowing back to the end surface of one side of the plate roller.

[0091] Finally, the ink scraper is detachably arranged between the upper scraper pressure plate and the lower scraper pressure plate, so that the ink scraper is easy to replace, so that the operation and maintenance are simple.

[0092] The above is a specific description of the preferred implementation of the utility model, but the invention of the utility model is not limited to the described embodiments. Technical personnel familiar with the field can also make various equivalent deformations or substitutions without violating the spirit of the utility model. These equivalent deformations or substitutions are all included in the scope defined by the claims of this application.
