Detailed Implementation

[0016] The utility model will now be further described with reference to the accompanying drawings and specific embodiments: Please see Figure 1-6 According to an embodiment of the present invention, a quick sealing device for a convection oven drying cart includes an oven body 1, a movable plate 2 provided on the side of the oven body 1, a guide rail 3 provided on the movable plate 2 and the surface of the oven body 1, a drying cart 4 provided inside the oven body 1, a support plate 5 provided at the bottom of the drying cart 4, a pulley 6 provided at the bottom of the support plate 5, a blower 7 provided on the side of the oven body 1, and a fixing plate 8 provided on the inner side of the oven body 1. When it is necessary to remove the drying cart 4 from the oven body 1 to facilitate the removal of items on the drying cart 4, the pulley 6 can be rotated and connected to the guide rail 3. This reduces the friction between the bottom of the drying cart 4 and the movable plate 2 and the inner surface of the oven body 1, and facilitates the displacement of the drying cart 4 to make it easier for subsequent workers to remove items from the drying cart 4.

[0017] A sealing plate 9 is provided inside the oven body 1, and an air supply pipe 10 is inserted into the sealing plate 9. A placement groove 11 is provided on the side of the sealing plate 9, and an inflatable sealing ring 12 is provided in the placement groove 11. The blower 7, in conjunction with the air supply pipe 10, makes the inflatable sealing ring 12 inflated, so that the inflatable sealing ring 12 can make tight contact with the side of the drying cart 4 and quickly seal it, thus preventing the loss of hot air inside the oven body 1.

[0018] Please see Figures 1-5 As shown in the figure, the drying cart 4 is fixedly connected to the surface of the support plate 5. A baffle 13 is provided on the upper surface of the drying cart 4. The pulley 6 is fixedly connected to the bottom of the support plate 5. The fixing plate 8 is fixedly connected to the inner side of the oven body 1. There are multiple sets of fixing plates 8. A moving groove 14 is opened on the side of one set of fixing plates 8. A sealing gasket 19 is provided on the surface of the fixing plate 8. When the air-filled sealing ring 12 is inflated, the drying cart 4 is slightly displaced, causing the support plate 5 and the baffle 13 to squeeze and seal the sealing gasket 19.

[0019] Please see Figure 4 and Figure 5As shown, a mounting plate 15 is arranged at the bottom of the support plate 5, a positioning hole 16 is provided on the side surface of the mounting plate 15, a hole is opened on the end surface of the moving groove 14, a positioning rod 17 is arranged in the moving groove 14, and one end of the positioning rod 17 passes through the hole opened on the end surface of the moving groove 14. A limiting spring 18 is sleeved on the surface of the positioning rod 17, one end of the limiting spring 18 is fixedly connected to the end surface of the moving groove 14, and the other end of the limiting spring 18 is fixedly connected to the surface of the positioning rod 17. After the drying cart 4 is moved into the oven body 1, the positioning rod 17 automatically resets by means of the elastic force of the limiting spring 18, so that one end of the positioning rod 17 is inserted into the positioning hole 16 opened on the side surface of the mounting plate 15. Through the cooperation of the positioning rod 17 and the positioning hole 16, the drying cart 4 is conveniently fixed inside the oven body 1, and the problem of offset of the drying cart 4 inside the oven body 1 is avoided.

[0020] Please refer to Figures 6-8 As shown, the sealing plate 9 is in a "匚"-shaped plate structure, the inflatable sealing ring 12 is fixedly connected in the placement groove 11, one end of the gas transmission pipe 10 is connected to the inflation end of the inflatable sealing ring 12, and the other end of the gas transmission pipe 10 is fixedly connected to the gas outlet end of the blower 7. The sealing plate 9 is arranged in the "匚"-shaped plate structure, which facilitates the contact between the surfaces of the two groups of inflatable sealing rings 12 and the upper and lower end surfaces of the side of the drying cart 4 to achieve a sealing effect.

[0021] According to the above solution of the present utility model, the present utility model facilitates moving the drying cart 4 out of the oven body 1 through the cooperation of the guide rails 3 and the pulleys 6. After the drying cart 4 is fixed in the oven body 1, the blower 7 cooperates with the gas transmission pipe 10 to inflate the inflatable sealing ring 12, so that the inflatable sealing ring 12 quickly contacts the side surface of the drying cart 4, and sealing is realized through the tight fitting between the inflatable sealing ring 12 and the side surface of the drying cart 4. The other side surface of the oven body 1 is sealed by a sealing gasket 19, so that the hot air in the oven body 1 will not be lost from the side surface of the drying cart 4, which improves the utilization rate of hot air by the drying cart 4 and reduces the drying time.
