Description

Technical Field

[0001] The utility model relates to the field of large ovens, in particular to a wind regulating plate structure for a large oven. Background Art

[0002] Large ovens can dry the sprayed products. The drying speed of the products depends on the temperature and the surface air flow rate. When there are many products in the oven, in order to avoid the problem that the drying speeds of different products in the oven vary greatly, it is necessary to make the temperatures and air flow rates on the surfaces of products in different areas similar. In the inner cavity of the current large ovens, although the wind plates installed at the hot air outlets have multiple air outlets to make the coverage range of the hot air larger, the air outlet direction of each air outlet is fixed and cannot be adjusted. As a result, the heat distribution is uneven in some parts of the oven due to the large or small amount of hot air, leading to problems such as poor drying effect or long baking time for the final batch of products. Content of the Utility Model

[0003] The purpose of the utility model is to provide a wind regulating plate structure for a large oven, which is beneficial to adjusting the temperature uniformity of the large oven and is convenient to adjust.

[0004] To achieve the above purpose, the utility model provides a wind regulating plate structure for a large oven, which includes a base plate. An installation part adapted to the furnace body is provided on the base plate. A number of ventilation holes and wind regulating plates that can swing a certain angle relative to the ventilation holes are provided on the base plate. One side edge of the wind regulating plate cooperates with one side edge of the ventilation hole.

[0005] As a further improvement of the utility model, at least one group of two parallel first strip-shaped grooves are provided on the base plate. One end of each of the two first strip-shaped grooves in each group is connected to one end of a second strip-shaped groove; the other end of the second strip-shaped groove is adjacent to the end of the other first strip-shaped groove in the group, and the interval between them forms the connection part between the base plate and the wind regulating plate. The connection part is made of a material with plastic deformation ability.

[0006] As a further improvement of the utility model, the first strip-shaped grooves on the base plate are parallel to each other, and the second strip-shaped grooves are perpendicular to the first strip-shaped grooves.

[0007] As a further improvement of the utility model, one side of the wind regulating plate is rotatably connected to the base plate through a rotating shaft, and an angle adjusting structure is further provided between the wind regulating plate and the base plate.

[0008] As a further improvement of the utility model, the angle adjusting structure includes a support rod. One end of the support rod is hinged to the base plate, and a locking structure is provided between the other end of the support rod and the wind regulating plate.

[0009] As a further improvement of the present utility model, the locking structure includes a fixing part provided on the air regulating plate. The fixing part is provided with at least two slots, and the arrangement direction of each slot is parallel to the width direction of the air regulating plate; the locking structure further includes a bolt, and the bolt is arranged at one end of the support rod and is inserted and matched with the slot.

[0010] As a further improvement of the present utility model, the number of ventilation holes on the substrate is multiple and arranged in at least two rows and at least two columns.

[0011] As a further improvement of the present utility model, the installation part is an installation hole.

[0012] Beneficial effects

[0013] Compared with the prior art, the advantages of the air regulating plate structure for a large oven of the present utility model are as follows:

[0014] 1. Through the operation of personnel, each air regulating plate on the substrate can swing a certain angle relative to the ventilation holes as needed, so that the hot air and heat distribution entering the large oven can be made as uniform as possible, improving the temperature uniformity of the large oven, and thus improving the drying efficiency of the oven for products.

[0015] 2. The air regulating plate is formed by slotting on the substrate, and the air regulating plate is only connected to the edge of the ventilation hole on the substrate through the connecting part. Since the connecting part is made of a material with the ability of plastic deformation, after the air regulating plate is rotated a certain angle relative to the ventilation hole manually, the air regulating plate can be fixed at this position without resetting, which is convenient for personnel to adjust the angle of the air regulating plate according to the needs of the oven. The substrate and the air regulating plate of this structure can be made into an integral structure. During production, only the first strip-shaped groove and the second strip-shaped groove need to be processed on the substrate by processing equipment, with a simple structure and low production cost.

[0016] 3. The ventilation plate can also be rotatably connected to the substrate through a rotating shaft, and the included angle between the ventilation plate and the ventilation hole is fixed by a support rod and a locking structure. When the angle of the ventilation plate needs to be adjusted, only need to insert the bolt of the support rod into different slots on the fixing part of the air regulating plate, which is convenient and labor-saving to adjust.

[0025] Now, embodiments of the present utility model will be described with reference to the accompanying drawings.

[0026] Embodiment 1

[0027] The detailed implementation manners of the present utility model are as Figures 1 to 5 shown. An air regulating plate structure for a large oven includes a base plate 1. The base plate 1 is provided with an installation part 11 adapted to the furnace body 9 of the large oven. The base plate 1 is provided with a plurality of ventilation holes 6 and an air regulating plate 5 that can swing at a certain angle relative to the ventilation holes 6. One side edge of the air regulating plate 5 cooperates with one side edge of the ventilation holes 6.

[0028] The base plate 1 is provided with multiple groups of two parallel first strip-shaped grooves 2 in each group. One end of each first strip-shaped groove 2 in each group is connected to one end of a second strip-shaped groove 3. The other end of the second strip-shaped groove 3 is arranged adjacent to the end of the other first strip-shaped groove 2 in the group. The interval between the two forms a connecting part 4 between the base plate 1 and the air regulating plate 5. The connecting part 4 is made of a material with plastic deformation ability. In this embodiment, the air regulating plate structure is an integral sheet metal structure. The air regulating plate 5 is formed by cutting out the first strip-shaped grooves 2 and the second strip-shaped grooves 3 on the base plate 1 during production. After bending the air regulating plate 5 to form a certain angle relative to the base plate 1, ventilation holes 6 are formed between the air regulating plate 5 and the base plate 1.

[0029] The first strip-shaped grooves 2 on the base plate 1 are parallel to each other, and the second strip-shaped grooves 3 are perpendicular to the first strip-shaped grooves 2. The air regulating plate 5 is square. The width of both the first strip-shaped grooves 2 and the first strip-shaped grooves 2 is 5 mm, and the distance between the adjacent ends of the second strip-shaped groove 3 and the first strip-shaped groove 2 is 5 mm, and the sheet metal at this place is not cut off.

[0030] The air outlet adjustment area of the large oven is very large, and the number of ventilation holes 6 to be adjusted is also very large. Therefore, the structure of the air deflector needs to be simple. This air deflector structure can adjust the flow direction of the hot air in the furnace body 9, so that the hot air is concentrated on the workpiece in the middle and the temperature uniformity in the furnace body is adjusted.

[0031] The number of ventilation holes 6 on the substrate 1 is multiple and arranged in at least two rows and at least two columns. The more the number of rows and columns of the ventilation holes 6, the more the number of air deflectors 5 available for adjustment, and the more uniform the distribution of the hot air and heat entering the furnace body 9 through the air deflector structure.

[0032] The installation part 11 is an installation hole. During installation, the screw passes through the installation hole of the installation part 11 and is threadedly connected to the edge of the air outlet in the furnace body 9. When the fan drives the hot air to pass through each ventilation hole 6 on the substrate 1, the hot air is blown in the corresponding direction under the action of the air deflector 5. As the angle between the air deflector 5 and the substrate 1 changes, the air volume of the ventilation hole 6 also changes.

[0033] Embodiment 2

[0034] As Figure 6 shown, the difference from Embodiment 1 is that both the upper and lower ends on the same side of the air deflector 5 are rotatably connected to the substrate 1 through a rotating shaft 7, and an angle adjustment structure is also provided between the air deflector 5 and the substrate 1.

[0035] Among them, the angle adjustment structure includes a support rod 83. One end of the support rod 83 is hinged to the substrate 1, and a locking structure is provided between the other end of the support rod 83 and the air deflector 5. The included angle between the substrate 1 and the air deflector 5 can be locked through the locking structure.

[0036] The locking structure includes a fixing part 81 provided on the air deflector 5. At least two slots 82 are provided on the fixing part 81. In this embodiment, there are four slots 82 on each fixing part 81. The arrangement direction of each slot 82 is parallel to the width direction of the air deflector 5. The locking structure also includes a bolt 84. The bolt 84 is slidably arranged at one end of the support rod 83 and is inserted and matched with the slot 82. When it is necessary to lock the angle of the air deflector 5, just let the bolt 84 pass through one end of the support rod 83 and insert it into the corresponding slot 82.

[0037] The present invention has been described above in combination with the best embodiments, but the present invention is not limited to the above-disclosed embodiments, and should cover various modifications and equivalent combinations made according to the essence of the present invention.
