Description

Technical Field

[0001] This utility model relates to the field of coating technology, specifically to a coating die head mechanism and an extrusion coating device. Background Technology

[0002] In extrusion coating, the slurry is sprayed through the lip of the die and coated onto a substrate such as an electrode. Different slurries have different properties such as solid content, density, and viscosity, and therefore the optimal coating angle will also be different. Thus, different users have different coating requirements.

[0003] The coating die head mechanism of an existing extrusion coating apparatus generally includes two vertical plates arranged opposite each other, two sliding plates, two forward and backward moving components, and a die head assembly. The top of each vertical plate has a notch. The two sliding plates are slidably disposed at the bottom of the notches on the two vertical plates. The two forward and backward moving components drive the two sliding plates to move forward and backward. The die head assembly is located between the two sliding plates and includes two side plates arranged opposite each other, a die head base plate, a die head mounting plate disposed at the top of the die head base plate, and a die head disposed at the top of the die head mounting plate. The two side plates are fixedly connected to the two sliding plates. The die head base plate is disposed between the two side plates. One end of the die head extends forward, and the other end of the die head has a lip. In actual operation, the two forward and backward moving components drive the two sliding plates to move backward, thereby moving the two side plates, the die head base plate, the die head mounting plate, and the die head backward. This allows the lip of the die head to contact the substrate, such as an electrode sheet, that passes over the coating roller of the extrusion coating apparatus. Subsequently, the slurry is sprayed out through the lip of the die head and coated onto the substrate.

[0004] In the above structure, since there is no angle adjustment structure for driving the die head to rotate, the angle of the die head cannot be adjusted, and therefore the coating angle cannot be adjusted, which fails to meet the coating needs of different users. Utility Model Content

[0053] In other embodiments, the angle adjustment assembly 50 includes an angle motor disposed on the outer side of the corresponding angle mounting plate 13a. The output ends of the angle motors of the two angle adjustment assemblies 50 are respectively connected to the other ends of the two rotating shafts 311. The angle motors of the two angle adjustment assemblies 50 are used to drive the two rotating shafts 311 to rotate, thereby causing the two side plates 31 to rotate around the axes of the two rotating shafts 311. This type of angle adjustment assembly simplifies the structure and facilitates assembly.

[0054] The other ends of the two rotating shafts 311 are respectively rotatably mounted on two angle mounting plates 13a. Specifically, two connecting sleeves 14 are respectively provided on the outer side of the two angle mounting plates 13a. The other ends of the two rotating shafts 311 pass through the through holes of the two angle mounting plates 13a and are respectively rotatably mounted in the two connecting sleeves 14.

The angular contact ball bearing 312 is set in the corresponding connecting sleeve 14 to provide rotational support for the rotating shaft 311. The number of angular contact ball bearings 312 can be set according to the actual situation. A sealing plate 141 is provided at the end of the connecting sleeve 14 to close the end of the connecting sleeve 14 away from the angle mounting plate 13a, thereby protecting the angular contact ball bearing 312.

[0055] One end of each of the two rotating shafts 311 is respectively disposed on the outer side of the two side plates 31. Specifically, the outer side of the side plate 31 is provided with a side plate through hole, and one end of each of the two rotating shafts 311 is respectively disposed in the side plate through hole of the corresponding side plate 31.

This can prevent the die head 34 from rotating and ensure the stability of the coating when coating the substrate through the die head 34. The number of the first mounting hole 151, the second mounting hole, the oblong hole 152, and the round hole 313 can be set according to the actual situation. The locking block 15 can be disassembled and installed by disassembling and installing the fasteners and locking the fasteners.

[0058] Furthermore, combined Figures 3 to 6 As shown, two reinforcing plates 131 are respectively provided on the opposite sides of the two sliding plates 13. The two reinforcing plates 131 correspond to the two upright plates 11. The reinforcing plates 131 are slidably disposed on the outer side of the corresponding upright plates 11 via guide rail assemblies. The back-and-forth movement of the two sliding plates 13 can drive the two reinforcing plates 131 to move back and forth. The two reinforcing plates 131 can strengthen the two sliding plates 13, preventing the two sliding plates 13 from being unable to move back and forth due to excessive deformation of the die head mounting plate 33, thus ensuring the smooth progress of coating.

[0059] The guide rail assembly includes a guide rail 134 and a sliding block 135 that slides with the guide rail 134. The guide rail 134 is disposed on the outer side of the corresponding upright plate 11, and the sliding block 135 is disposed on the inner side of the reinforcing plate 131. The portion of the guide rail 134 protruding from one end of the reinforcing plate 131 is accommodated in a third accordion cover 138.

One end of the fourth accordion cover 139 is connected to the other end of the reinforcing plate 131, and the other end of the fourth accordion cover 139 is connected to the outer side of the corresponding upright plate 131. During the movement of the reinforcing plate 131, the third bellows cover 138 and the fourth bellows cover 139 are retractable, and the third bellows cover 138 and the fourth bellows cover 139 protect the guide rail 134.

[0060] The coating roller 70 is located behind the die head assembly 30 and corresponds to the lip 341 of the die head 34. Both ends of the coating roller 70 are rotatably disposed inside the two vertical plates 11 of the coating die head mechanism 10. In this embodiment, the inner side of the vertical plates 11 is provided with vertical plate holes, and both ends of the coating roller 70 are rotatably disposed within the vertical plate holes of the two vertical plates 11 via two coating roller bearings. The coating roller 70 is used to support the substrate.

[0061] A coating drive mechanism 80 is disposed on the outer side of one of the vertical plates 11 and is used to drive the coating roller 70 to rotate. The coating drive mechanism 80 includes a coating motor 81 and a coating reducer 82. The coating reducer 82 is disposed on the outer side of one of the vertical plates 11, and the coating motor 81 is mounted on the coating reducer 82. The output end of the coating motor 81 is connected to the input end of the coating reducer 82, and the output end of the coating reducer 82 is connected to one end of the coating roller 70. The coating motor 81 drives the coating roller 70 to rotate via the coating reducer 82.

[0062] In actual operation, the two locking blocks 15 are first removed. Then, the level is used to check whether the mold base plate 32 is parallel to the ground. If it is not parallel, the two angle adjustment components 50 drive the two side plates 31 to rotate around the axes of the two rotating shafts 311, thereby driving the mold base plate 32, the mold mounting plate 33 and the mold 34 to rotate around the axes of the two rotating shafts 311 so that the mold base plate 32 is parallel to the ground. Then, the angles of the two angle sensors 60 are zeroed. If they are parallel, the angles of the two angle sensors 60 are directly zeroed and this position is set as the zero position. Then, the two side plates 31 are driven to rotate around the axes of the two rotating shafts 311 by the two angle adjustment components 50 respectively. This drives the die head base plate 32, the die head mounting plate 33 and the die head 34 to rotate around the axes of the two rotating shafts 311, so as to adjust the coating angle. The rotation angle of the two side plates 31 is detected in real time by the two angle sensors 60 until the angle meets the user's requirements. Thus, the coating angle adjustment is completed. Then, the two locking blocks 15 are reinstalled to lock the two side plates 31 and the two angle mounting plates 13a together. This locks the die head assembly 30 and the two angle mounting plates 13a together.

[0063] After the substrate passes over the coating roller 70, the left and right moving assembly 40 drives the die head 34 to move left and right to adjust the left and right position of the die head 34 so that the lip 341 corresponds to the substrate. Then, the two forward and backward moving assemblies 20 drive the two sliding plates 13 to move backward, thereby driving the die head 34 to move backward so that the lip 341 contacts the substrate. Then, the coating drive mechanism 80 drives the coating roller 70 to rotate and the slurry is delivered into the channel of the die head 34 through the slurry supply equipment. Subsequently, the slurry is sprayed out through the lip 341 and coated onto the substrate.
