All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

As shown in fig. 1 to 7, an embodiment of the present invention provides an air guide assembly for a tuyere, including:

at least one wind shielding mechanism 2 arranged along the length direction of the air port; each wind shielding mechanism 2 comprises a first surface 21 and two first side surfaces 22 respectively connected with the first surface 21, and the two first side surfaces 22 are oppositely arranged; wherein, the first surface 21 is opposite to the tuyere, and one edge of the two first side surfaces 22 far away from the first surface 21 is respectively connected to two long edges of the tuyere.

The air guide assembly can be arranged on an air port of the air outlet nozzle body 1 and comprises at least one wind shielding mechanism 2, and the wind shielding mechanism 2 can correspondingly shield the position of a blank area of a product to be air-dried; specifically, the wind shielding mechanism 2 is approximately in a cube shape and comprises a first surface 21 opposite to the wind gap and two first side surfaces 22, one ends of the two first side surfaces 22 of the wind shielding mechanism 2, which are far away from the first surface 21, are connected with the edge of the wind gap, so that a certain distance is formed between the first surface 21 and the wind gap, and the distance between the first surface 21 and the wind gap is closer to the distance between products (battery pole pieces) to be air-dried, thereby effectively shielding a blank area of the products, preventing hot air at the wind gap from diffusing to the blank area of the products from two sides of the wind shielding mechanism 2, reducing the amount of the hot air contacting with the blank area, reducing the heating degree of the blank area to offset negative effects, specifically reducing deformation and wrinkles of substrates (such as pole piece foils) in the blank area, and improving the conditions of edge cracking and the like of a coating layer (active material layer on the pole piece) close to the blank area; further, the wind shielding mechanism 2 is not easily detached or damaged, and does not need to be replaced frequently. In summary, the air guide assembly of the embodiment of the invention can effectively improve the yield of the coated and dried product (battery pole piece).

Specifically, the following describes a specific structure and an operation effect of the air guide assembly according to the embodiment of the present invention, taking a battery pole piece as a coating and drying product as an example. Since a typical oven has an upper tuyere (tuyere facing downward) and a lower tuyere (tuyere facing upward) which are opposite to each other up and down, the above tuyere is used as an example in the present embodiment, and the lower tuyere is also applicable.

Specifically, as shown in fig. 1, for convenience of understanding and description of the embodiment of the present invention, the length direction of the outlet body 1 is set to be the first direction x, and the width direction is set to be the second direction y. In the wind shielding mechanism 2, a first surface 21 is opposite to the wind gap and is parallel to a first direction x and a second direction y, two first side surfaces 22 are opposite and are arranged along the second direction y, and each first side surface 22 is parallel to the first direction x and is perpendicular to the first surface 21.

In a specific embodiment, as shown in fig. 2 to 7, each of the first side surfaces 22 is provided with a first opening 31.

After being blocked by the wind shielding mechanism 2, the wind blown out from the wind gap can flow to two sides of the wind shielding mechanism 2 from the first openings 31 on the two first side surfaces 22, that is, the blocked wind can flow out along two sides (front and rear sides) of the wind shielding mechanism 2 in the second direction, so as to reduce the outflow along two sides (left and right sides) of the wind shielding mechanism 2 in the first direction x, thereby reducing the influence on the wind gap flow field on two sides of the wind shielding mechanism 2, that is, reducing the interference on the flow field above the coating area as much as possible.

For example, as shown in fig. 2, 4 and 7, the first opening 31 of each first side 22 may include a plurality of holes, as shown in fig. 3, 5 and 6, and the first opening 31 may be a single hole; specifically, the first side 22 may be a mesh (e.g., a circular mesh, or a strip, a twill, etc.).

In a specific embodiment, as shown in fig. 1 to 4 and 7, the wind shielding mechanism 2 may further include a second side surface 23. As shown in fig. 2 to 4, the windshield 2 includes two second side surfaces 23, the two second side surfaces 23 are disposed opposite to each other, and each second side surface 23 is connected to the first surface 21 and the two first side surfaces 22. Specifically, as shown in fig. 1, two second side surfaces 23 are opposite and arranged along the first direction x, and each second side surface 23 is parallel to the second direction y and perpendicular to the first surface 21.

Specifically, as shown in fig. 2 to 4, the first surface 21, the two first side surfaces 22 and the two second side surfaces 23 of the wind shielding mechanism 2 constitute a box body, only one side of the box body is open, and the open side is opposite to the first surface 21 and is used for receiving the inlet wind at one side of the wind gap; the first surface 21 and the two second side surfaces 23 in the wind shielding mechanism 2 can ensure that the shielded wind does not flow out through the left side and the right side; meanwhile, the box body of the wind shielding mechanism 2 is in a non-closed design, and the first openings 31 arranged on the front first side surface 22 and the rear first side surface 22 can guide the shielded wind to flow out in the front-rear direction; that is, in this embodiment, the wind shielding mechanism 2 can guide the wind in the wind gap to be parallel to the pole piece from the direction perpendicular to the pole piece and discharge the wind in the front-back direction, so as to ensure that the wind does not blow to the pole piece, and the wind does not cause residual drying effect on the pole piece and influence the hot wind flow field on the two sides of the blank area.

Illustratively, as shown in fig. 1, the width of the wind shielding mechanism 2 along the first direction x is larger than the minimum margin width of the product related to coating and drying pole pieces at present and smaller than the maximum margin width of the product related to battery pole pieces at present, and on the basis of the width, the width can be widened by 10mm-20mm to shield hot air in the margin edge coating area, for example, the width can be 60mm specifically.

Exemplarily, the first surface, the first side and the second side of the wind shielding mechanism adopt plates made of the same material, the material can be stainless steel, aluminum alloy, steel plates, copper plates, non-metal plates and the like, the processing mode can be a metal plate mode, a casting mode, a milling mode and the like, and the thickness can be 1mm-5 mm.

In a specific embodiment, the wind shielding mechanism 2 further includes a guide plate, such as the guide plate 41 in fig. 4 and the guide plate 42 in fig. 5, disposed in a space enclosed by the first surface 21 and the two first sides 22. Specifically, the guide plate is configured to guide the wind blown from the tuyere to the outside of the space. Specifically, a space enclosed by the first surface 21 and the two first side surfaces 22 is a cubic space enclosed by the wind shielding mechanism 2, and when the wind shielding mechanism 2 includes the second side surface 23, the space is a space enclosed by the first surface 21, the first side surface 22, and the second side surface 23.

The utility model discloses a wind shielding mechanism, including wind shielding mechanism, guide plate, wind guiding mechanism and wind guiding mechanism.

In a particular embodiment, as shown in fig. 4, the wind-shielding means 2 comprises two second side faces 23; the guide plate 41 is opposite to the first surface, and two ends 410 close to the two first side surfaces 22 are respectively inclined towards one side of the tuyere; the first opening 31 on the first side surface 22 is located on the side of the guide plate 41 facing the tuyere. Specifically, the guide plates 41 may be connected to the two first side surfaces 22 respectively near both ends 410 of the two first side surfaces 22.

In the wind shielding mechanism 2 of the present embodiment, the two second side surfaces 23 can ensure that the shielded wind does not flow out through the left and right sides; the guide plate 41 is opposite to the first surface 21, and the two ends 410 close to the two first side surfaces 22 incline and tilt towards the wind ports, and the sheltered wind can flow to the first holes 31 of the two first side surfaces 22 along the two ends 410 of the guide plate 41 and is guided out, so that the influence on the drying of the pole piece caused by the fact that the position where the horizontal flow-out is too low (too close to the pole piece) leads to diffusion and then reaches the pole piece can be avoided.

In another specific embodiment, as shown in fig. 5, the wind shielding mechanism 2 is not provided with a second side surface; the guide plate 42 is opposite to the first surface of the wind shielding mechanism 2, the cross section of the guide plate 42 parallel to the first side surface 22 is an arc shape S, and two ends of the arc shape S extend to one side back to the wind gap. Specifically, both ends of the arc S may be connected to the first surface.

The wind shielding mechanism 2 of the present embodiment does not have the second side surface; the deflector 42 is relative with first surface 21, and the both ends along first direction are to keeping away from wind gap orientation slope backward, can be with the wind direction left and right sides that is sheltered from with certain angle outflow downwards, compare in directly flowing out about first surface and can reduce the disturbance to the former wind field of left and right sides, make simultaneously that the wind energy heat that is sheltered from can be used for the product drying, make full use of wind energy, reduce energy loss.

Illustratively, as shown in fig. 5 and 6, a second opening 32 may also be provided on the first surface 21; also, the first opening 31 on the first side 22 is located between the guide plate 42 and the first surface 21.

Specifically, the second opening 32 is formed in the first surface 21 and can be used for bottom air return, air diffused from the periphery can flow into an air return cavity formed between the guide plate 42 of the wind shielding mechanism 2 and the first surface 21 from the second opening 32, and the first opening 31 in the first side surface 22 is located between the guide plate 42 and the first surface 21, so that the air flowing into the air return cavity can flow out from the first openings 31 in the front side and the rear side.

For example, as shown in fig. 5 and 6, in this embodiment, the first opening 31 may have an arc shape matching the shape of the cross section of the guide plate 42, so as to facilitate the air flow in the return air chamber to flow out of the first opening 31.

In another specific embodiment, an edge of the first surface of the wind shielding mechanism is curved and inclined, and is configured to guide wind blown from the wind gap to the outside of the wind shielding mechanism. In other words, the first surface of the wind shielding mechanism may be configured as a wind deflector to guide the wind blown from the wind gap. Specifically, the specific arrangement of the first surface of the wind shielding mechanism may be the same as that of the wind deflectors described in the above embodiments, and details are not repeated herein.

In a specific embodiment, as shown in fig. 1, the air guiding assembly may further include a pair of sliding rails 5, where the pair of sliding rails 5 are respectively installed on two long edges of the air opening, and the extending direction of the pair of sliding rails 5 is the same as the extending direction (the first direction x) of the two long edges; one edge of the two first sides 22 of each wind-shielding mechanism 2, which is far away from the first surface 21, is provided with a sliding connection piece; the two sliding connectors of each wind shielding mechanism 2 are respectively connected with the pair of sliding rails 5 in a sliding manner.

Specifically, each wind shielding mechanism 2 can slide along the sliding rail 5, so that the long edge (the first direction x) of the air opening can be movably adjusted, the shielding area can be flexibly changed, and the drying operation of pole piece products of different models is adapted.

Illustratively, the air guide assembly has a locking member disposed between the wind shielding mechanism 2 and the slide rail 5, and the locking member is configured to lock the relative positions of the slide rail 5 and the wind shielding mechanism 2. Therefore, the relative positions of the sliding connecting piece and the sliding rail can be locked under the condition of no driving, and the influence on the drying effect of the product due to the position change of the wind shielding mechanism is avoided.

Specifically, for example, a latch, a positioning block, a positioning hole, or a bolt and nut assembly may be added to a corresponding mating portion of the sliding connector and the sliding rail of the wind shielding mechanism, so that the relative position of the sliding connector and the sliding rail can be locked without driving, and the influence on the drying effect of the product due to the position change of the wind shielding mechanism is avoided. Alternatively, a magnetic body may be disposed between the slide link and the slide rail so that the slide link and the slide rail of each wind shielding mechanism magnetically attract each other to achieve locking, and for example, a magnetic material may be plated on the surfaces of the slide rail and the slide link.

For example, the wind guide assembly of the embodiment of the invention may further include a driving device configured to drive the wind shielding mechanism to slide along the sliding rail. Illustratively, the driving mode can be air cylinder driving, motor screw driving and the like.

In a specific embodiment, the at least one wind shielding mechanism comprises at least two wind shielding mechanisms; the sizes of different wind shielding mechanisms are different, and the different wind shielding mechanisms can be nested, namely, the shielding areas of the different wind shielding mechanisms can be overlapped.

Furthermore, the slide rail includes with two kinds of at least sliding support poles that keep out the wind mechanism one-to-one, different kinds of mechanisms that keep out the wind slide along the bracing piece that corresponds separately, and do not block each other. Furthermore, the position and the overlapping area of the wind shielding mechanism can be flexibly adjusted according to the blank width and the position of the product. Specifically, for example, when the margin width is large, different wind shielding mechanisms can move in a matching manner, and the width of a shielding area is changed by overlapping and nesting partial areas so as to adapt to drying objects of different models; alternatively, when used to dry products with more whitespace, the original nested wind-blocking mechanisms can be separated to increase the number of blocked areas.

In a specific embodiment, as shown in fig. 1, the at least two wind shielding mechanisms 2 include two types, namely, a first wind shielding mechanism 201 and a second wind shielding mechanism 202; the first wind-shielding mechanism 201 can be inserted into the second wind-shielding mechanism 202, and the second wind-shielding mechanism 202 is slightly larger in size because the second wind-shielding mechanism 202 is capable of accommodating the first wind-shielding mechanism 201, and the specific size can be determined according to the wall thickness.

Further, the pair of slide rails 5 includes a pair of first type slide support rods 51 corresponding to the first type wind shielding mechanism 201 and a pair of second type slide support rods 52 corresponding to the second type wind shielding mechanism 202, and the pair of first type slide support rods 51 and the pair of second type slide support rods 52 are parallel to each other; the two sliding connectors of the first wind shielding mechanism 201 are respectively connected with the pair of first sliding support rods 51 in a sliding manner; the two sliding connectors of the second wind shielding mechanism 202 are respectively connected with the pair of second sliding support rods 52 in a sliding manner; the first wind-shielding mechanism 201 can slide along the first sliding support rod 51, and the second wind-shielding mechanism 202 can slide along the second sliding support rod 52, so that the first wind-shielding mechanism 201 is nested in the second wind-shielding mechanism 202.

Specifically, in this embodiment, the two layers of the wind shielding mechanisms 2 of the first wind shielding mechanism 201 and the second wind shielding mechanism 201 are included, and therefore, the slide rail 5 includes two rows of support rods of the first sliding support rod 51 and the second sliding support rod 52 correspondingly to serve as the slide rails of the two layers of the wind shielding mechanisms 2, specifically, the second sliding support rod 52 corresponds to the outer layer wind shielding mechanism (the second wind shielding mechanism 202), the first sliding support rod 51 corresponds to the outer layer wind shielding mechanism (the first wind shielding mechanism 201), the distance (height) from the second sliding support rod 52 to the edge of the wind gap may be greater than the distance (height) from the first sliding support rod 51 to the edge of the wind gap, and the width between the two second sliding support rods 52 may be greater than the width between the two first sliding support rods 51, so that the first wind shielding mechanism 201 and the second wind shielding mechanism 202 may slide along the first sliding support rod 51 and the second sliding support rod 52 respectively without obstructing each other I.e. the two tiers of wind-deflecting means may slide freely along the respective tracks to effect nesting or separation.

Illustratively, the first sliding support bar 51 and the second sliding support bar 52 can be fixed on the two long edges of the tuyere by welding, connecting members (e.g., screws), bonding, and fastening, wherein the two first sliding support bars 51 are symmetrically arranged, and the two second sliding support bars 52 are symmetrically arranged.

Illustratively, the first and second sliding support rods 51 and 52 have the same shape and length, for example, as shown in fig. 8, each support rod may have an L-shaped cross section with two perpendicular flanges, one flange 501 may be welded to the edge of the tuyere, and the other flange 502 may be used to overlap the sliding connector, as shown in fig. 3 and 7, and correspondingly, the sliding connector may be the flange 20 connected to the first side 22 of the wind shielding mechanism 2, or a slider may overlap the other flange 502 of the support rod, and may restrain the wind shielding mechanism from moving by damping due to gravity or electromagnetic force.

Illustratively, the thickness of two folded edges of the supporting rod can be 1mm-5mm, the supporting rod can be made of stainless steel, aluminum alloy, steel plates, copper plates, non-metal plates and the like, and the processing mode can be a metal plate, casting, milling and the like.

For example, as shown in fig. 1, the distance between the first surface of the first wind shielding mechanism 201 and the pole piece can be 1mm-20mm, and the distance between the first surface of the second wind shielding mechanism 202 and the pole piece can be 1mm-10mm, and the specific difference between the two depends on the thickness of the first surface of the wind shielding mechanism 2 and the actual installation requirement. The distance between the two first side surfaces 22 of the first wind shielding mechanism 201 matches the distance between the two first sliding support rods 51, and the distance between the two first side surfaces 22 of the second wind shielding mechanism 202 matches the distance between the two second sliding support rods 52.

When different wind shielding mechanisms are installed, an inner wind shielding mechanism (such as a first wind shielding mechanism) can be installed firstly, an outer wind shielding mechanism (such as a second wind shielding mechanism) is installed after the position is adjusted, and then the position and the overlapping area of the wind shielding mechanism are flexibly adjusted according to the width and the position of the reserved white.

Specifically, the wind guide assembly provided in the above embodiment includes two wind shielding mechanisms and two pairs of support rods, however, the wind guide assembly of the present invention is not limited to the above embodiment, and in practical applications, the number of the wind shielding assemblies and the number of the support rods may be determined according to the number of the blanks and the width of the products to be coated. For example, for manufacturing battery pole pieces, the number of the support rods can be increased from two pairs to three pairs, four pairs or more, and the types and the number of the wind shielding mechanisms are correspondingly increased, so that the shielding area can be adjusted more flexibly to adapt to different numbers of coating blanks.

In a specific embodiment, as shown in fig. 1 to 4, the first wind shielding mechanism 201 may include two second side surfaces 23; as shown in fig. 1 and 7, the second wind shielding mechanism 202 includes at most one second side surface 23. In this case, the first windshield 2 can be inserted into the second windshield 2 through an opening on the side of the second windshield 2 not provided with the second side. Of course, the second wind-shielding mechanism 202 may not be provided with the second side surface, and the first wind-shielding mechanism 201 may have only one second side surface 23 or no second side surface, and may be nested.

In a specific embodiment, as shown in fig. 1, the wind guide assembly according to the embodiment of the present invention may include three first wind shielding mechanisms 201 and one second wind shielding mechanism 202, where the second wind shielding mechanism 202 is located between any two adjacent first wind shielding mechanisms 201; specifically, the second wind shielding mechanism 202 may be sleeved with a middle first wind shielding mechanism 201. For example, the second wind deflector 202 has a second side, which has two of the first wind deflectors 201 on the side facing the interior of the cube of the second wind deflector 202, wherein a first wind deflector 201 adjacent to the second wind deflector 202 can be inserted into the second wind deflector 202, overlapping the shaded region of the second wind deflector 202.

It should be noted that the above embodiment is only an example of the air guide assembly, and when in specific use, different numbers of wind shielding mechanisms may be installed as required, and if one of the pole pieces has one coating width, two wind shielding mechanisms are installed; if two coating widths are needed, one wind shielding mechanism is arranged at the position corresponding to the middle blank leaving position, one wind shielding mechanism is arranged when the blank leaving width is small, and the other wind shielding mechanism is arranged when the blank leaving width is wide, so that the two overlapped wind shielding mechanisms can be sleeved to ensure that the blank leaving width is completely shielded; if three coating widths correspond to the middle white space, a wind shielding mechanism is required to be installed.

The embodiment of the invention also provides a wind nozzle assembly which comprises the wind guide assembly.

In addition, the embodiment of the invention also provides an oven, which comprises the air guide assembly described in any one of the above, or comprises the air nozzle assembly described above.

For example, the oven may include an upper air guide assembly and a lower air guide assembly which are opposite to each other, specifically, the air opening of the upper air guide assembly faces downward, the wind shielding mechanism is located below the air opening and used for shielding the air flow output downward, and conversely, the air opening of the lower air guide assembly faces upward, and the wind shielding mechanism is located above the air opening and used for shielding the air flow output upward.

At present, the oven provided by the embodiment of the invention is applied to coating of a pilot-scale line negative electrode product, has an obvious improvement effect on the white wrinkles of the product, and particularly has a good improvement effect on the coating edge cracking of low-cost graphite.

It will be apparent to those skilled in the art that various changes and modifications may be made in the embodiments of the present invention without departing from the spirit and scope of the invention. Thus, if such modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include such modifications and variations.
