Detailed Description

The present invention will be further described with reference to the accompanying drawings. The following examples are only for illustrating the technical solutions of the present invention more clearly, and the protection scope of the present invention is not limited thereby.

As shown in fig. 1 to 4: the embodiment discloses a modularization heated air circulation oven, including box 1 and air heater 3, 1 top of box is equipped with the fan mounting groove 12 that the cross-section is the rectangle, and two vertical sides of fan mounting groove 12 all are equipped with splint 2, and splint 2 can be followed 1 upper surface longitudinal sliding of box and connect and be used for driving splint 2 to the gliding resilient means of fan mounting groove 12, and the horizontal side of fan mounting groove 12 is equipped with horizontal sealing layer 5.

The longitudinal and transverse directions in this embodiment are the vertical and horizontal directions, respectively, of the view of fig. 3, for ease of description only.

The longitudinal direction and the transverse direction of the air heater 3 are respectively provided with a longitudinal boss 31 and a transverse boss 32, and the height of the longitudinal boss 31 is preferably higher than that of the transverse boss 32.

When the air heater 3 is connected to the fan mounting groove 12, the inner edge of the clamping plate 2 is pressed against the side part of the air heater 3 under the action of the elastic device, the clamping plate 2 drags the longitudinal boss 31, and the transverse boss 32 covers the transverse sealing layer 5 to realize sealing.

In order to improve the sealing performance between the clamping plate 2 and the hot air blower 3, a compression sealing device is further arranged between the clamping plate 2 and the longitudinal boss 31.

Specifically, the method comprises the following steps: the extrusion sealing device comprises an outer sealing strip 25 and a pressing plate 4, wherein the outer sealing strip 25 is arranged between the clamping plate 2 and the longitudinal boss 31, and the pressing plate 4 is used for enabling the longitudinal boss 31 to extrude the outer sealing strip 25.

The pressing action of the pressure plate 4 on the longitudinal boss 31 is achieved by: the pressing plate 4 is hinged to the upper end of the hinge rod 24, the lower end of the hinge rod 24 is fixedly connected to the clamping plate 2, a top thread 41 and a pressing foot 42 are respectively arranged at two ends of the pressing plate 4, the end portion of the top thread 41 is connected with the clamping plate 2, and the lower end of the pressing foot 42 is pressed against the upper surface of the longitudinal boss 31 and used for enabling the pressing foot 42 at the other end to extrude the longitudinal boss 31. It should be noted that the hinge point of the pressing plate 4 and the hinge rod 24 is located between the top thread 41 and the presser foot 42, and the lifting of the presser foot 42 needs to be high enough to meet the requirement of mounting and dismounting the longitudinal boss 31.

In order to make the inner edge (end) of the pressing plate 2 tightly fit with the side of the air heater 3, the inner edge of the clamping plate 2 of the present embodiment is further provided with an end sealing strip 22, and the cross section of the end sealing strip 22 is preferably arc-shaped.

The inner edge of the fan mounting groove 12 is further provided with an inner sealing strip 121, and the inner sealing strip 121 is used for connecting the lower surface of the clamping plate 2. When splint 2 and fan mounting groove 12 do not coincide completely, the interior edge of splint 2 does not enter into fan mounting groove 12 promptly, and the last edge of interior sealing strip 121 is higher than the upper surface of box 1 under its own elastic action, when splint 2's interior edge entered into fan mounting groove 12, can promote interior sealing strip 121, can realize better sealing like this between splint 2 and box 1 (refer to fig. 2).

The splint 2 and the specific structure which can longitudinally slide along the upper surface of the box body 1 and has certain elasticity are as follows: splint 2 is equipped with waist shape hole 23, and waist shape hole 23 passes through screw 43 and connects in the upper surface of box 1, and the resilient means of this embodiment is spring 21, and splint 2 is connected to spring 21 one end, and the other end connection sets up in the dog 11 of box 1. The number of springs 21 is preferably multiple, which is advantageous for achieving a uniform force.

During manufacturing, the specification of the box body 1 (mainly the size of the fan installation groove 12) can be fixed, the peripheral sizes of the longitudinal boss 31 and the transverse boss 32 (namely the transverse length of the transverse boss 32 and the height of the longitudinal boss 31 in the view of fig. 4) are fixed, and the air heaters 3 with different specifications are designed according to different products. When the hot air blower 3 needs to be replaced, the top thread 41 is loosened, the longitudinal boss 31 can be taken out from the lower part of the pressing plate 4, and the hot air blower 3 can be replaced. After the hot air blower 3 is installed, the longitudinal boss 31 extrudes the outer sealing strip 25 and the transverse boss 32 extrudes the transverse sealing layer 5 under the extrusion of the pressing plate 4, so that the hot air blower 3 and the upper end of the box body 1 can be sealed. Because air heater 3 can carry out quick replacement, consequently can change whole air heater 3 according to actual product demand. In the manufacturing process, after the specifications of the fan mounting groove 12, the longitudinal boss 31 and the transverse boss 32 are fixed, the hot air blower 3 with various specifications can be configured in the same box body 1.

By adopting the hot air circulating oven of the embodiment, the hot air blowers 3 with various specifications can be configured on one box body 1, the adjusting width of each parameter (including temperature, airflow, humidity and the like) of hot air is increased, and the drying requirements of different products are met. Because the air heaters 3 with various specifications are configured, the working parameter range of a single air heater 3 is not required to be as large as that set in the prior art, the air heaters 3 are favorably positioned in a more ideal working environment, and the extreme operation is avoided.

The foregoing is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, a plurality of modifications and variations can be made without departing from the technical principle of the present invention, and these modifications and variations should also be considered as the protection scope of the present invention.
