Technical Field
[0001] The utility model relates to the technical field of coating oven components, in particular to a humidity regulating device for a coating oven. Background Art
[0002] The lithium battery coating oven is a key equipment in the lithium battery production process, which is mainly used to dry the slurry coated on the lithium battery pole piece.
[0003] After entering winter, the relative humidity of outdoor air will be significantly reduced, which will reduce the moisture content of the air introduced from the outside into the oven, which will lead to a faster evaporation rate of the water in the negative electrode slurry during the baking process in the oven, and finally lead to the phenomenon of electrode cracking during the negative electrode coating process. In order to solve the cracking of the electrode caused by low humidity, the oven is often humidified during the baking process of the electrode. As recorded in the text entitled "A Fresh Air Pretreatment System" with the publication number CN212856488U, a humidifier is set in the fresh air duct to increase the humidity of the fresh air discharged into the oven by the fresh air duct. However, since the position and angle of the fresh air duct remain fixed, when the humidified fresh air is sent into the oven through the fresh air duct, water mist is often sprayed in a fixed and directional manner through the air outlet of the fresh air duct, so the area of its action is often a small area. Spraying water mist for a long time will make the humidity in the area too high, and there is a problem of insufficient uniformity in regulating the overall humidity in the oven, which needs to be solved urgently.

[0010] As a further solution of the utility model: a ball is installed on the outer end of the inner rod.
[0011] As a further solution of the utility model: a push plate is fixed on the side of the humidifying spray plate away from the exhaust end of the fresh air square tube, and the push plate abuts against the flip top piece to push the humidifying spray plate to flip outward.

[0013] As a further solution of the utility model: the power mechanism is a screw slider mechanism.
[0014] Compared with the prior art, the beneficial effects of the utility model are:
[0015] 1. By setting the humidifying spray plate connected to the humidifier at the outlet end of the fresh air square tube, and driving the humidifying spray plate to slide back and forth perpendicular to the axis of the fresh air square tube through a power mechanism, the humidifying spray plate can achieve multi-directional humidification of the oven. In addition, flip top pieces are provided at both ends of the sliding path of the humidifying spray plate, so that when the humidifying spray plate slides to the end of the sliding path, it is squeezed and flipped outward by the flip top piece, converting the traditional linear spray with fixed position and angle into a movable spray within the range of the conical surface, effectively improving and ensuring the uniformity of the humidification of the oven, and also improving the diffusion speed of the water mist in the oven.
[0016] 2. Both ends of the humidifying spray plate are fixedly connected to the two sliders through rubber columns, which not only enables the humidifying spray plate to spray along the axis of the fresh air square tube toward the outside of the fresh air square tube under normal conditions, but also due to the elasticity of the rubber column, the rubber column can be twisted when subjected to torsion, to ensure that the humidifying spray plate can be flipped after abutting against the flip top piece; and after the humidifying spray plate is separated from the flip top piece, the humidifying spray plate can be flipped and reset again under the elastic action of the rubber column 32, ensuring the stable operation of the multi-directional spray of the humidifying spray plate.
[0017] 3. A through long hole is provided on the humidifying spray plate, which penetrates the humidifying spray plate along the axial direction of the fresh air square tube.

[0018] 4. The flip top piece includes a sleeve and an inner rod constituting a sleeve-type telescopic rod, and a support spring is installed in the sleeve to drive the inner rod to stretch out of the sleeve.

[0020] 6. A push plate is fixed on the side of the humidifying spray plate away from the exhaust end of the fresh air square tube. The push plate abuts against the flip top piece to push the humidifying spray plate to flip outward, effectively increasing the torque of the flip top piece in the process of pushing the humidifying spray plate to flip, making it easier for the humidifying spray plate to flip under the abutment of the flip top piece.
[0021] 7. In the humidifying tube connecting the humidifying spray plate and the humidifier, the connection with the humidifying spray plate is set as a corrugated telescopic tube, which prevents the humidifying tube from hindering the sliding of the humidifying spray plate and can achieve stable connection with the humidifier during the sliding process of the humidifying spray plate.

DETAILED DESCRIPTION
[0029] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0030] For ease of understanding, the specific structure and working mode of the utility model are further described below in conjunction with the accompanying drawings:
[0031] The specific structure of the utility model refers to Figure 1-5 As shown, its main structure includes a fresh air square tube 10 and a humidifying spray plate 30 that reciprocates along the vertical direction at the air outlet end of the fresh air square tube 10. Among them, from the perspective that the fresh air square tube 10 is placed horizontally, the humidifying spray plate 30 is connected to the humidifier and driven by a power mechanism 50 to reciprocate along the vertical direction, and the humidifying spray plate 30 sprays along the axial direction of the fresh air square tube 10 toward the outside of the fresh air square tube 10 under normal conditions, and water mist is supplied to the humidifying spray plate 30 through the humidifier, and the humidifying spray plate 30 reciprocates to achieve multi-directional spraying. In addition, the humidifying spray plate 30 can rotate around a horizontal axis perpendicular to the axial direction of the fresh air square tube 10, and a flip top piece 40 fixed to the fresh air square tube 10 is provided at both ends of the sliding path of the humidifying spray plate 30, and when the humidifying spray plate 30 moves to the end of the travel path, the flip top piece 40 pushes the humidifying spray plate 30 to flip outward, thereby increasing the expansion angle of the humidifying spray plate 30 spraying outward, as shown in FIG. Figure 5 As shown, the traditional linear spray with fixed position and angle is converted into a movable spray within the conical surface, which effectively improves the uniformity of oven humidification and increases the diffusion speed of water mist in the oven.
[0032] Specifically, Figure 1 and Figure 2As shown, both sides of the inner wall of the fresh air square tube 10 are provided with slide grooves 11 distributed along the vertical direction of the groove length, and the humidifying spray plate 30 is a horizontal long strip structure perpendicular to the axis of the fresh air square tube 10, and both ends of the humidifying spray plate 30 are respectively slidably connected to the two slide grooves 11 through sliders 31, ensuring the stable sliding of the humidifying spray plate 30 along the vertical direction. In addition, both ends of the humidifying spray plate 30 are respectively fixedly connected to the two sliders 31 through rubber columns 32, which not only allows the humidifying spray plate 30 to maintain the spraying along the axis of the fresh air square tube 10 toward the outside of the fresh air square tube 10 under normal conditions, but also due to the elasticity of the rubber column 32, the rubber column 32 can be twisted when receiving torsion, so as to ensure that the humidifying spray plate 30 can be reversed after contacting with the flip top member 40; and after the humidifying spray plate 30 is separated from the flip top member 40, the humidifying spray plate 30 can be flipped and reset again under the elastic action of the rubber column 32. Of course, there are other implementations for the humidifying spray plate 30 to achieve flipping and resetting after flipping, such as the humidifying spray plate 30 rotating between the two sliders 31 through the rotating shaft, assuming that two torsion springs are coaxially arranged on the rotating shaft, and the torsion springs have opposite torsion directions, and by selecting two torsion springs with appropriate torsion forces, the humidifying spray plate 30 sprays along the axis of the fresh air square tube 10 toward the outside of the fresh air square tube 10 under normal conditions, and after the humidifying spray plate 30 can be separated from the abutment of the flip top member 40, the humidifying spray plate 30 can be driven by the torsion spring to flip and reset. In addition, the torsion spring in the above implementation can be changed to two tension springs with one end at the top and bottom of the humidifying spray plate 30, and the other ends of the two tension springs are fixed to the slider 31, and the tension of the tension spring is used to drive the humidifying spray plate 30 to flip, which can also achieve the above effect.
[0033] Further, such as Figure 3 As shown, the humidifying spray plate 30 is provided with a through long hole 33 that penetrates the humidifying spray plate 30 along the axial direction of the fresh air square tube 10. The through long hole 33 is provided so that convection is formed in the inner cavity of the through long hole 33 during the air intake process of the fresh air square tube 10, so that the water mist introduced into the through long hole 33 by the nozzle can be quickly diffused outward. In addition, the hole length direction of the through long hole 33 is horizontally distributed, and the nozzles of the humidifying spray plate 30 are arranged to be uniformly distributed on the inner wall of the through long hole 33 along the hole length direction of the through long hole 33, so that the water mist can be uniformly diffused into the oven within the hole length range of the through long hole 33, which not only ensures the uniformity of the water mist spraying, but also ensures the range of the water mist spraying due to the long strip hole structure of the through long hole 33, further improving the humidification effect of the air in the oven.
[0034] On the basis of the above, if Figure 4As shown, the flip top member 40 includes a sleeve 41 and an inner rod 42 constituting a sleeve-type telescopic rod. The axis of the sleeve-type telescopic rod is distributed along the sliding direction of the humidifying spray plate 30. The sleeve 41 is fixed to the inner wall of the fresh air square tube 10, and an extrusion spring 44 is installed in the sleeve 41 to drive the inner rod 42 to stretch out of the sleeve 41. When the flip top member 40 abuts against the humidifying spray plate 30, the compression of the extrusion spring 44 may achieve buffering, thereby reducing the collision damage between the humidifying spray plate 30 and the flip top member 40. In addition, a ball 43 is installed at the outer end of the inner rod 42. During the abutment and flipping process of the humidifying spray plate 30 and the outer end of the inner rod 42, the rolling friction between the ball 43 and the humidifying spray plate 30 effectively reduces the friction resistance between the humidifying spray plate 30 and the outer end of the inner rod 42 during the flipping process.
[0035] In order to make the humidification spray plate 30 better flip, Figure 2 As shown, a push plate 34 is fixed on the side of the humidifying spray plate 30 away from the exhaust end of the fresh air square tube 10, and the push plate 34 abuts against the flip top piece 40 to push the humidifying spray plate 30 to flip outward, effectively increasing the torque of the flip top piece 40 in the process of pushing the humidifying spray plate 30 to flip, making it easier for the humidifying spray plate 30 to flip under the abutment of the flip top piece 40.
[0036] On the basis of the above, if Figure 1 As shown, the humidifying spray plate 30 is connected to the humidifier through the humidifying pipe 20, and the connecting section of the humidifying pipe 20 and the humidifying spray plate 30 passes through the fresh air square pipe 10, and the through section is a corrugated telescopic pipe 21 distributed along the vertical direction. The bellows telescopic pipe 21 is telescopic, so that the humidifying pipe 20 does not hinder the up and down movement of the humidifying spray plate 30, and can still maintain a good connection between the humidifying pipe 20 and the humidifying spray plate 30. Of course, the humidifying pipe 20 can also be connected to the humidifying spray plate 30 in the form of a flexible hose or a metal bellows, which can also achieve the above effect.
[0037] On the basis of the above, if Figure 1 As shown, the power mechanism 50 is a screw slider mechanism, which is a linear drive mechanism commonly used in the prior art, specifically, including a screw rod distributed along the vertical direction, the screw rod is driven by a servo motor, and the screw rod passes through the slider 31 and forms a screw slider structure with the slider 31. The servo motor drives the screw rod to rotate forward and reverse, which can realize the reciprocating drive of the humidifying spray plate 30 along the vertical direction, and can effectively ensure the stability of the reciprocating motion of the humidifying spray plate 30. Of course, the power mechanism 50 can also adopt other embodiments, such as cylinders, electric cylinders or rope drives, etc., which can realize linear motion in the prior art.
[0038] Of course, for those skilled in the art, the present invention is not limited to the details of the exemplary embodiments described above, but also includes the same or similar structures that can be implemented in other specific forms without departing from the spirit or basic features of the present invention. Therefore, no matter from which point of view, the embodiments should be regarded as exemplary and non-restrictive, and the scope of the present invention is defined by the appended claims rather than the above description, so it is intended to include all changes that fall within the meaning and scope of the equivalent elements of the claims. Any figure mark in the claims should not be regarded as limiting the claims involved.
[0039] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
[0040] The technology, shape and structure parts not described in detail in the present invention are all known technologies.
