Description

[0034] In order to make the technical problems solved by the utility model, the technical solutions adopted and the technical effects achieved clearer, the technical solutions of the embodiments of the utility model will be further described in detail below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the utility model.

[0035] In the description of the present invention, unless otherwise clearly specified and limited, the terms "connected", "connected", and "fixed" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0036] In the present utility model, unless otherwise clearly specified and limited, a first feature being "above" or "below" a second feature may include that the first and second features are in direct contact, or may include that the first and second features are not in direct contact but are in contact through another feature between them. Moreover, a first feature being "above", "above" and "above" a second feature includes that the first feature is directly above and obliquely above the second feature, or simply indicates that the first feature is higher in level than the second feature. A first feature being "below", "below" and "below" a second feature includes that the first feature is directly below and obliquely below the second feature, or simply indicates that the first feature is lower in level than the second feature.

[0037] like Figures 1 to 3As shown, the utility model provides a rectifying mechanism 1, including a rectifying structure 10 and a driving member 11. The rectifying structure 10 includes a mounting portion 100, a rectifying plate 101 and a guide plate 102, the mounting portion 100 is used to be detachably connected to the air nozzle 20 of the oven, the rectifying plate 101 is fixedly connected to the mounting portion 100, one side of the rectifying plate 101 is a rectifying surface 101a, the guide plate 102 is rotatably connected to the edge of one side of the rectifying plate 101 away from the mounting portion 100, the axis 103 of the guide plate 102 rotating relative to the rectifying plate 101 is parallel to the rectifying surface 101a and the guide surface 102a of the guide plate 102, the driving member 11 is connected between the guide plate 102 and the rectifying plate 101, and the driving member 11 can drive the guide plate 102 to rotate relative to the rectifying plate 101.

[0038] Please combine Figure 4 As shown, the nozzle 20 of the oven can be detachably mounted by the mounting portion 100 of the rectifying structure 10, and the nozzle 20 of the oven can be modified so that the airflow blown out from the nozzle 20 first flows roughly vertically to the pole piece 3, then flows roughly along the direction parallel to the rectifying surface 101a to the guide plate 102, and finally moves away from the pole piece 3 along the guide surface 102a under the action of the Coanda effect. In the process of the airflow flowing to the guide plate 102 roughly along the direction parallel to the rectifying surface 101a, the part of the pole piece 3 corresponding to the rectifying surface 101a will be subjected to the force directed to the rectifying surface 101a under the action of the upper and lower wind pressure differences. This force can offset the impact force of the airflow blown out from the nozzle 20 on the pole piece 3 to a certain extent, so as to reduce the degree of bending of the pole piece 3 when passing through the nozzle 20, thereby reducing the shaking of the pole piece 3 during the drying process, wherein, Figure 4 The arrows in FIG. 2 show the approximate direction of the air flow between the air nozzle 20 , the rectifying mechanism 1 and the pole piece 3 .

[0039] The airflow is made to move away from the pole piece 3 along the guide surface 102a. On the one hand, the direction of the airflow can be controlled, reducing the influence of the airflow on the part of the pole piece 3 that does not correspond to the rectifying surface 101a and the air nozzle 20. On the other hand, the part of the pole piece 3 corresponding to the guide plate 102 can also be subjected to a certain force directed to the guide plate 102, so as to further reduce the shaking of the pole piece 3. In addition, by providing the driving member 11, the angle between the guide plate 102 and the rectifying plate 101 can be adjusted according to the specific conditions inside different ovens, so that the rectifying mechanism 1 is suitable for modifying more different ovens.

[0040] Optionally, the mounting portion 100 and the guide plate 102 do not protrude from the straightening surface 101 a , thereby preventing the mounting portion 100 and the guide plate 102 from affecting the flow direction of the airflow along the straightening surface 101 a .

[0041] Optionally, the mounting portion 100 may be connected to the air nozzle 20 by a detachable connection method including but not limited to threaded connection, clamping, and magnetic connection. For example, a through first mounting hole may be provided on the mounting portion 100, and a second mounting hole may be provided on the air nozzle corresponding to the first mounting hole. The bolt passes through the first mounting hole and the second mounting hole and is threadedly connected to the nut, so that the mounting portion 100 is threadedly connected to the air nozzle.

[0042] Optionally, the mounting portion 100 may be specifically a plate-like structure. In this case, the mounting portion 100 forms an angle with the rectifier plate 101 and is located on the side of the rectifier surface 101a facing the other plate surface of the rectifier plate 101. When the mounting portion 100 is detachably connected to the air nozzle 20, at least the plate surface of the mounting portion 100 that is away from the guide plate 102 abuts against the surface of the air nozzle 20, so that the effective connection area between the mounting portion 100 and the air nozzle 20 is larger, which can make the connection stability between the mounting portion 100 and the air nozzle 20 better. When in use, it is easy to keep the relative posture of the rectifier mechanism 1 as a whole and the air nozzle 20 stable, thereby making the reliability of the rectifying effect of the rectifier mechanism 1 better.

[0043] In addition, the mounting portion 100 is also a plate-like structure, so that the rectifying structure 10 can be composed of a plate-like structure. Therefore, when manufacturing the rectifying structure 10, the connected mounting portion 100 and the rectifying plate 101, as well as the separate guide plate 102 can be obtained by stamping using a plate, and then the guide plate 102 can be rotatably connected to the rectifying plate 101. In other words, the manufacturing and molding steps and the connection steps of the mounting portion 100 and the rectifying plate 101 can be implemented in the same process, so as to simplify the production steps of the rectifying structure 10 and reduce the production cost of the rectifying structure 10.

[0044] Exemplarily, the mounting portion 100, the rectifier plate 101 and the guide plate 102 can all be manufactured by stamping a stainless steel plate with a thickness of 0.8 mm to 1.2 mm, wherein the thickness of the pressed plate can be 0.8 mm, 0.85 mm, mm, 0.9 mm, 0.95 mm, 1 mm, 1.05 mm, 1.1 mm, 1.15 mm or 1.2 mm, etc.

[0045] The rectifier plate 101 and the guide plate 102 form an angle θ. As the angle θ increases, the rectifier surface 101a of the rectifier plate 101 and the guide surface 102a tend to be parallel. Therefore, the effect of the guide plate 102 in guiding the airflow away from the pole piece 3 is smaller. Therefore, the angle θ cannot be too large. However, when the angle θ is too small, the angle between the guide surface 102a and the rectifier surface 101a changes too much, making it difficult to effectively form the Coanda effect, thereby causing the guide plate 102 to fail to guide the airflow away from the pole piece 3. It can be seen that the angle θ cannot be too large or too small. Based on this, optionally, the angle θ can satisfy: 110°≤θ≤160°. For example, the angle θ can be 110°, 115°, 120°, 125°, 130°, 135°, 140°, 145°, 150°, 155° or 160°, etc.

[0046] In the direction perpendicular to the axis 103 and parallel to the rectifying surface 101a, the rectifying plate 101 has a dimension d1, and in the direction perpendicular to the axis 103 and parallel to the guide surface 102a, the guide plate 102 has a dimension d2. Optionally, the dimension d1 and the dimension d2 satisfy: d1>d2, so that the rectifying surface 101a can have a larger area, so as to be able to rectify the airflow in a larger range, and make the pole piece 3 receive a greater force directed to the guide plate 102 due to the wind pressure difference, so as to better reduce the bending degree of the pole piece 3 when passing through the wind nozzle 20. At the same time, the guide plate 102 is smaller in size, which can make the guide plate 102 lighter in weight, so as to avoid the bending of the rectifying surface 101a of the rectifying plate 101 due to the excessive weight of the guide plate 102.

[0047] It can be understood that the larger the size d1 of the rectifying plate 101, the better the rectifying effect of the rectifying mechanism 1. In order to avoid interference between the rectifying mechanism 1 and the adjacent air nozzles 20, the size d1 of the rectifying plate 101 cannot exceed the spacing between the adjacent air nozzles 20. When the adjacent air nozzles 20 are also provided with rectifying mechanisms 1, in order to avoid interference between the rectifying mechanisms 1 and the rectifying mechanisms 1 on the adjacent air nozzles 20, the size d1 of the rectifying plate 101 can be at most half of the spacing between the adjacent air nozzles 20. In the oven, the distance between adjacent air nozzles 20 is usually about 200 mm. Based on this, in order to make the rectifier plate 101 as large as possible while not easily interfering with other structures, optionally, the size d1 of the rectifier plate 101 can satisfy: 100 mm ≤ d1 ≤ 200 mm. For example, the size d1 can be 100 mm, 110 mm, 120 mm, 130 mm, 140 mm, 150 mm, 160 mm, 170 mm, 180 mm, 190 mm or 200 mm, etc.

[0048] In other embodiments, d1 may also be less than 100 mm, for example, d1 may also be 95 mm, 90 mm, 85 mm, 80 mm, 75 mm, 70 mm, 65 mm, 60 mm, 55 mm, 50 mm, 45 mm, 40 mm, etc., so that the rectifier plate 101 can be suitable for ovens with smaller spacing between adjacent air nozzles 20.

[0049] The larger the size d2 of the guide plate 102 is, the heavier the weight of the guide plate 102 is, the easier it is for the rectifier plate 101 to bend, resulting in a decrease in the flatness of the rectifier surface 101a and a decrease in the rectifying effect of the rectifier plate 101. Therefore, the smaller the size d2 is, the better. The guide plate 102 also needs to provide a certain connection position for the drive member 11, so the size d2 cannot be too small. Based on this, optionally, the size d2 of the guide plate 102 can satisfy: 20mm≤d2≤50mm. For example, the size d2 can be 20mm, 25mm, 30mm, 35mm, 40mm, 45mm or 50mm, etc.

[0050] Optionally, the size d1 of the rectifying plate 101 can satisfy: 100mm≤d1≤200mm, while the size d2 of the guide plate 102 can satisfy: 20mm≤d2≤50mm, so that the rectifying effect reliability of the rectifying structure 10 is better and the overall structure of the rectifying structure 10 is more reasonable.

[0051] Optionally, along the extension direction of the axis 103, the size of the rectifying plate 101 and the guide plate 102 can be adapted to the size of the air nozzle 20. In other words, along the extension direction of the axis 103, the size of the rectifying plate 101, the guide plate 102 and the air nozzle 20 can be the same, so that the rectifying mechanism 1 has a more comprehensive rectifying effect on the airflow flowing out of the air outlet 200 of the air nozzle 20. Among them, illustratively, along the extension direction of the axis 103, the size of the existing air nozzle 20 is usually 600mm to 1200mm, therefore, along the extension direction of the axis 103, the size of the rectifying plate 101 and the guide plate 102 can be the same and both meet 600mm to 1200mm, for example, the size of the rectifying plate 101 and the guide plate 102 can be the same and be 600mm, 700mm, 800mm, 900mm, 1000mm, 1100mm or 1200mm, etc.

[0052] In some optional embodiments, the driving member 11 is directly connected between the guide plate 102 and the rectifier plate 101. For example, the driving member 11 may be a driving member 11 such as a cylinder or a linear motor that can be used to output telescopic motion. The two opposite ends of the driving member 11 are respectively hinged to the guide plate 102 and the rectifier plate 101. Alternatively, the driving member 11 may be a driving member 11 such as a swing motor or a rotating motor that can be used to output rotational motion. The driving member 11 is fixedly disposed on one of the guide plate 102 and the rectifier plate 101, and the output end of the driving member 11 is fixedly connected to the other of the two.

[0053] In some other optional embodiments, one end of the driving member 11 is connected to the guide plate 102, and the other end of the driving member 11 is connected to the mounting portion 100 or is used to connect to the air nozzle 20, so as to be indirectly connected to the rectifying plate 101, so that the distance between the two opposite ends of the driving member 11 can be larger, and it is easy to drive the guide plate 102 to achieve a more accurate angle adjustment. Among them, when the other end of the driving member 11 is connected to the mounting portion 100, the driving member 11 can be installed on the air nozzle 20 along with the mounting portion 100, so that the installation process of the rectifying mechanism 1 is more convenient, and when the other end of the driving member 11 is used to connect to the air nozzle 20, the distance between the two ends of the driving member 11 can be larger, so that the driving member 11 drives the guide plate 102 to rotate relative to the rectifying plate 101 for fine adjustment. The adjustment accuracy can be higher.

[0054] Exemplarily, the driving member 11 can be a driving member 11 such as a cylinder or a linear motor that can be used to output telescopic motion. The two opposite ends of the driving member 11 are respectively hinged to the rectifier plate 101 and the mounting portion 100, or are respectively hinged to the rectifier plate 101 and the air nozzle 20.

[0055] Optionally, the driving member 11 can output telescopic movement, one end of the driving member 11 is hinged to the guide plate 102, and the other end of the driving member 11 is hinged to the mounting member 12, and the mounting member 12 is used for detachable connection to the air nozzle 20, so that during installation, it is only necessary to install and fix the mounting member 12 to the air nozzle 20, and the other end of the driving member 11 can be hinged to the air nozzle 20.

[0056] Optionally, the rectification mechanism 1 includes a plurality of driving members 11, and the plurality of driving members 11 are arranged at intervals along the extension direction of the axis 103, so as to increase the number of driving members 11 to improve the stability of adjusting the relative angle between the rectification plate 101 and the guide plate 102 by driving the driving members 11, and to support the rectification plate 101 after the adjustment is completed, so as to improve the stability of the relative position of the rectification plate 101 and the guide plate 102.

[0057] Optionally, the guide plate 102 can be rotatably connected to the rectifier plate 101 through a damping hinge 104, so that a certain damping force can be provided through the damping hinge 104, so that after the rectifier plate 101 and the guide plate 102 are adjusted to a desired relative angle through the driving member 11, the relative position stability of the rectifier plate 101 and the guide plate 102 is better, which can improve the reliability of the rectification function of the rectification mechanism 1.

[0058] Optionally, the rectifier mechanism 1 also includes a wind speed detection component 13, and the rectifier plate 101 is also provided with a through hole that penetrates along the thickness direction of the rectifier plate 101 itself. The wind speed detection component 13 is connected to the side of the rectifier plate 101 that is away from the rectifier surface 101a, and the detection head 130 of the wind speed detection component 13 is passed through the through hole and extends to protrude from the rectifier surface 101a. The wind speed detection component 13 is connected to the driving member 11 through wired or wireless communication, so that during the actual use of the rectifier mechanism 1, the actual wind speed between the rectifier surface 101a and the pole piece 3 can be detected in real time through the wind speed detection component 13, and then the driving member 11 can be controlled according to the actual wind speed, so that the driving member 11 can adjust the angle between the guide plate 102 and the rectifier plate 101 in real time.

[0059] Specifically, the smaller the actual wind speed, the less significant the Coanda effect of the airflow is. Therefore, it is more necessary to reduce the angle θ between the rectifying plate 101 and the guide plate 102 (that is, the relative posture of the rectifying plate 101 and the guide plate 102 can be adjusted by the driving member 11 to make the angle θ close to 110°) to increase the change angle between the guide surface 102a and the rectifying surface 101a, thereby improving the effect of the guide plate 102 in guiding the airflow away from the pole piece 3. When the actual wind speed is higher, the Coanda effect of the airflow is The more significant the Coanda effect is, the larger the angle θ between the rectifier plate 101 and the guide plate 102 can be (that is, the relative posture of the rectifier plate 101 and the guide plate 102 can be adjusted by the driving member 11 to make the angle θ close to 160°), thereby preventing the high-speed airflow from suddenly turning at a large angle under the guidance of the guide plate 102 and generating turbulence, which in turn leads to unstable air pressure on the side of the pole piece 3 corresponding to the guide plate 102, thereby causing the pole piece 3 to shake.

[0060] When the impact force exerted by the air nozzle 20 on the pole piece 3 is too large, it is difficult to achieve a relatively balanced force on the pole piece 3 through the tension exerted on the pole piece 3 by the pressure difference of the air flow corresponding to the side of the rectifying surface 101a of the pole piece 3. If the wind speed output by the air nozzle 20 is too small, it will lead to a poor baking effect on the pole piece 3. Therefore, optionally, the wind speed detection component 13 is used to communicate with the blowing component of the oven, so that when the baking wind speed detected by the wind speed detection component 13 is too large or too small, the blowing flow rate of the blowing component can be adjusted first to make the air flow rate output by the air nozzle appropriate.

[0061] Under normal circumstances, the air flow velocity between the pole piece 3 and the rectifying surface 101a can be within the range of 5m / s to 15m / s. At this time, the impact force of the air flow output by the wind nozzle 20 on the pole piece 3 will not be too large, and the wind speed output by the wind nozzle 20 will not be too small. Based on this, optionally, the wind speed detection component 13 also stores a baking wind speed range, and the baking wind speed range is 5m / s to 15m / s. Therefore, when the wind speed detection component 13 detects that the actual wind speed between the rectifying surface 101a and the pole piece 3 is outside the baking wind speed range (that is, the detected actual wind speed is less than 5m / s or greater than 15m / s), the blowing flow rate of the blowing component can be adjusted according to the actual wind speed, so that the actual wind speed between the rectifying surface 101a and the pole piece 3 is within the baking wind speed range.

[0062] Optionally, when the wind speed detection component 13 detects that the actual wind speed between the rectifier surface 101a and the pole piece 3 is outside the baking wind speed range, only the blowing component can adjust the blowing flow rate without causing the driving component 11 to adjust the angle θ between the rectifier plate 101 and the guide plate 102; when the wind speed detection component 13 detects that the actual wind speed between the rectifier surface 101a and the pole piece 3 is within the baking wind speed range, the driving component 11 adjusts the angle θ between the rectifier plate 101 and the guide plate 102 according to the actual wind speed detected by the wind speed detection component 13.

[0063] like Figure 5 As shown, the utility model also provides an oven 2, comprising a plurality of air nozzles 20 and a rectifying mechanism 1 as described in the aforementioned technical solution, wherein the plurality of air nozzles 20 are arranged at intervals along a predetermined direction S, and at least one side of at least one air nozzle 20 along the predetermined direction S is correspondingly provided with a rectifying mechanism 1, and the mounting portion 100 of the rectifying mechanism 1 is connected to the corresponding air nozzle 20, and the rectifying surface 101a of the rectifying mechanism 1 is flush with the plane where the air outlet 200 of the air nozzle 20 is located, wherein the predetermined direction S is parallel to the moving direction of the pole piece 3 in the oven 2, and by installing the aforementioned rectifying mechanism 1, the shaking of the pole piece 3 during the drying process can be reduced, thereby improving the performance and yield of the pole piece 3.

[0064] It can be understood that the aforementioned “at least one side of at least one air nozzle 20 along the predetermined direction S is correspondingly provided with a rectifying mechanism 1” specifically means that at least one side of at least one air nozzle 20 along the predetermined direction S is correspondingly provided with a rectifying mechanism 1, or at least one air nozzle 20 along the predetermined direction S Both sides are correspondingly provided with a rectifying mechanism 1.

[0065] Optionally, when two adjacent air nozzles 20 are each provided with a rectifying mechanism 1 only on one side, the two adjacent air nozzles 20 may be provided with a rectifying mechanism 1 on the same side along the predetermined direction S, so that a single rectifying mechanism 1 can have more installation space.

[0066] Optionally, the oven 2 may further include an air blowing assembly, which is communicatively connected to the wind speed detection assembly 13 of the rectifier mechanism so as to be able to adjust the air flow of the air blowing assembly according to the actual wind speed detected by the wind speed detection assembly 13, so as to better reduce the vibration of the pole piece 3 of the rectifier mechanism.
