[0033] Reference Figure 1-3 , a material box, comprising:

[0034] A material box body 1, which is used to contain slurry;

[0035] A right baffle 2 is hinged to the upper right end of the material box body 1 and can be arranged on the right side of the pressure roller 8 to prevent the slurry from splashing out of the material box;

[0036] A left baffle 3 is hinged to the upper left end of the material box body 1 and can be arranged on the left side of the pressure roller 8 to prevent the slurry from splashing out of the material box;

[0037] The material box body 1 , the right baffle 2 , and the left baffle 3 can be enclosed with the pressing roller 8 to form a material box having a cavity 4 .

[0038] The material box body 1, the right baffle plate 2, the left baffle plate 3 and the pressure roller 8 form a cavity; when the plate roller 7 is installed in the cavity, the right baffle plate 2, the left baffle plate 3 and the pressure roller 8 wrap the plate roller at full angles, so that the material box is fully enclosed on all sides, and the position where the plate roller 7 may splash the slurry when working is fully enclosed and blocked, thereby preventing the plate roller in the material box from causing the slurry to splash when working and affecting the operation of the equipment and the normal work of the workshop; and the right baffle plate 2, the left baffle plate 3 and the pressure roller 8 enclose the material box body 1, so that the contact area between the slurry and the external environment is reduced, the volatilization of the slurry solvent in the material box body 1 is slowed down, and the quality stability of the coating slurry is improved.

[0039] like Figure 2 As shown, further, the material box body 1 includes a front baffle 11 arranged on the front side thereof and a rear baffle 12 arranged on the rear side thereof, the two sides of the right baffle 2 respectively abut against the front baffle 11 and the rear baffle 12, and the two sides of the left baffle 3 respectively abut against the front baffle 11 and the rear baffle 12, so that a relatively stable force structure is formed among the front baffle 11, the rear baffle 12, the right baffle 2 and the left baffle 3.

[0040] Specifically, a hinge 92 is provided on the material box body 1, and a hinge column 91 is respectively provided on the right baffle 2 and the left baffle 3. The hinge 92 is provided with an opening, and the hinge 92 is sleeved outside the hinge column 91. When the right baffle 2 and the left baffle 3 drive their respective hinge columns 91 to hinge and rotate relative to the material box body 1, the hinge 92 rotates around the axis of the hinge column 91. The setting of the opening on the hinge 92 allows the right baffle 2 or the left baffle 3 to be quickly removed from the material box body 1.

[0041] Specifically, the right baffle 2 and the front baffle 11 are inclined to each other and are arranged at an angle above the material box body 1 to further improve the sealing of the cavity 4, reduce the splashing of slurry during the coating process, and further alleviate the volatilization of the solvent in the slurry.

[0042] Furthermore, a scraper inlet 6 for inserting a slurry scraper is provided on the right baffle plate 2. When in use, the scraper is inserted into the cavity 4 along the scraper inlet 6 to scrape off excess slurry on the plate roller to control the amount of coating, ensure that the coating uniformity and thickness meet the coating requirements, improve the coating quality, and package the performance of the coated lithium battery.

[0043] like Figure 1-2 As shown, specifically, the right baffle 2 includes an upper right baffle 21 and a lower right baffle 22;

[0044] The upper right baffle 21 is hinged to the front baffle 11 and the rear baffle 12;

[0045] The upper right baffle 21 and the lower right baffle 22 are relatively opened and closed to open or close the scraper inlet 6;

[0046] Specifically, when the scraper assembly enters the cavity 4, the upper right baffle 21 is first flipped to the left and opened. After the scraper assembly enters the cavity 4, the upper right baffle 21 is reset; the relative opening and closing of the upper right baffle 21 and the lower right baffle 22 enables the coating machine to operate normally when replacing the plate roller and adjusting the scraper assembly on the base coating machine.

[0047] Specifically, the front baffle 11 and / or the rear baffle 12 are provided with a limit pin. When the scraper inlet 6 is opened, the limit pin can limit the movement of the upper right baffle 21 to prevent the upper right baffle 21 from flipping upward and hitting the material belt running in the pressure roller 8, thereby damaging the coating quality. It can also prevent the upper right baffle 21 from resetting and interfering with the scraper assembly.

[0048] Specifically, one end of the lower right baffle 22 extends into the cavity 4, and the hinge between the lower right baffle 22 and the material box body 1 is arranged outside the cavity 4. When the scraper assembly enters the cavity 4, it rests on the lower right baffle 22. Due to the limitation of the connection relationship between the lower right baffle 22 and the material box body 1, the relative positions of the lower right baffle 22, the scraper assembly and the material box body 1 are stable.

[0049] like Figure 3 As shown, specifically, the material box body 1 further includes a slurry holding box 13 disposed below the right baffle 2, the left baffle 3, the front baffle 11 and the rear baffle 12;

[0050] The slurry holding box 13 is detachably connected to the right baffle 2, the left baffle 3, the front baffle 11 and the rear baffle 12, so that the right baffle 2 can be easily removed. When replacing the plate roller, the left baffle 3, the front baffle 11 and the rear baffle 12 can also be separated from the slurry holding box 13.

[0051] like Figure 5 As shown, further, the material box body 1 is provided with a slurry port 11 for the slurry to flow in.

[0052] Specifically, the hinge point between the left baffle 3 and the front baffle 11, and the hinge point between the left baffle 3 and the rear baffle 12 are both located at one end of the front baffle 11 and the rear baffle 12 close to the slurry holding box 13; when it is necessary to observe the slurry capacity of the slurry holding box 13, the left baffle 3 is flipped downward toward the outside of the material box. At this time, the material box is in an open state and can be inspected from the left side of the material box, so as to strengthen the control of the coating quality; after flipping the left baffle 3, the open space on the left side of the material box can also make way for the replacement of the plate roller.

[0053] Specifically, the slurry port 11 is disposed at the bottom of the slurry containing box 13 .

[0054] Furthermore, a material box lifting assembly is provided below the slurry holding box 13, and the material box lifting assembly is used to drive the slurry holding box 13 to rise and fall relative to the plate roller 7. When the base coater replaces the plate roller 7, the slurry holding box 13 descends, and other structures of the material box are fixed on the frame, which does not affect the operation of replacing the plate roller with a forklift.

[0055] The material box lifting assembly can drive the slurry holding box 13 to move relative to the right baffle 2, the left baffle 3, the front baffle 11 and the rear baffle 12, so as to facilitate the replacement of the plate roller.

[0056] A primer coating machine comprises: a frame, a material box as described above is arranged at the bottom of the frame, a pressure roller 8 is arranged between the right baffle 2 and the left baffle 3, and a plate roller 7 is arranged in the cavity 4.

[0057] Furthermore, shields 81 are provided at both ends of the pressing roller 8, and the shields 81 are used to prevent the slurry from splashing into the two ends of the pressing roller 8, thereby preventing the slurry from splashing during the film feeding process of the plate roller.

[0058] A right baffle, a left baffle and a pressure roller 8 are arranged above the material box body to prevent the slurry from splashing, so as to prevent the slurry from splashing when the plate roller 7 is working and affecting the operation of the equipment and the normal work of the workshop.

[0059] Furthermore, a scraper assembly is also provided on the frame.

[0060] When the primer coating machine of this embodiment is used, the slurry flows into the slurry containing box 13 from the slurry port 11, and the plate roller rolls in the slurry to absorb the slurry. When the slurry on the surface of the plate roller contacts the scraper assembly, the scraper assembly removes the excess slurry on the plate roller, and then the plate roller contacts the pressure roller 8 for primer coating;

[0061] During the high-speed operation of the plate roller, the slurry on the plate roller will mainly splash onto the right baffle 2, the left baffle 3, the front baffle 11 and the rear baffle 12. Then, the slurry flows back to the bottom of the slurry holding box 13 under the action of gravity and re-participates in the coating process, which not only prevents the slurry from splashing during the operation of the plate roller, but also completes the continuous circulation of the slurry, thereby improving the utilization rate of the slurry and the coating quality.

[0062] 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.
