[0003] Currently, in order to quickly melt the glue inside the degumming furnace, air ducts are generally arranged inside. These air ducts form a closed cycle inside the furnace body to ensure a uniform temperature field of the hot air circulation structure, thereby achieving a high temperature uniformity. However, the current air duct structure is simple and cannot change the air volume in different directions according to the distribution of the glue application amount of the internal objects, affecting the uniformity of glue melting. Summary of the Invention

[0004] The technical problem to be solved by the utility model is to provide a duct of a degumming furnace and a degumming furnace, which can change the air volume in different orientations according to the glue amount at different positions on the object, so as to solve the problems raised in the above background art.

[0005] The utility model is realized by the following technical solutions: A duct of a degumming furnace includes a degumming furnace body. A fixing ring is installed outside the degumming furnace body. A plurality of air inlet holes penetrating through the degumming furnace body and the fixing ring are provided on each of the four inner surfaces of the degumming furnace body. An annular shell is sleeved outside the fixing ring. A plurality of assembly ports are arranged in an annular structure on the outer circumferential surface of the annular shell. A blocking plate is arranged in each assembly port. An air inlet pipe is vertically installed at the top of the annular shell.

[0006] As a preferred technical solution, an annular positioning groove is provided on the outer circumferential surface of the fixing ring. A positioning ring is installed on the inner circumferential surface of the annular shell corresponding to the positioning groove, and the positioning ring is movably arranged in the positioning groove.

[0007] As a preferred technical solution, the length and width of the cross-section of the blocking plate are both matched with the length and width of the assembly port. Rubber layers are installed on the inner wall surfaces of the assembly ports. The outer side surface of the blocking plate is in contact with the inner side surface of the rubber layer. An arc-shaped groove is formed on the end surface of the blocking plate facing the fixing ring, and the arc degree of the arc-shaped groove is matched with the arc degree of the outer circle of the fixing ring. A hand-held port for a finger to extend into is provided at the other end of the blocking plate.

[0008] As a preferred technical solution, a plurality of support columns are vertically installed on the bottom surface of the degumming furnace body, and a bottom plate is installed at the lower ends of the plurality of support columns.

[0009] As a preferred technical solution, the widths of the blocking plates are all matched with the width of the inner cavity of the annular shell, and both ends of the blocking plates are in contact with the inner side surfaces inside the annular shell.

[0010] As a preferred technical solution, both the fixing ring and the annular shell are made of metal materials.

[0011] As a preferred technical solution, the inner circumferential surface of the annular shell is tightly attached to the outer circumferential surface of the fixing ring.

[0012] A debinding furnace includes the debinding furnace air duct described above.

[0013] The beneficial effects of the present utility model are as follows: The structure of the present utility model is simple. After an article is placed in the debinding furnace, the air volume in different directions can be changed according to the amount of glue on different directions of the article. When the amount of glue on the left side is less or there is no glue, the baffle on the left side can be pushed inward, so that the baffle can enter the annular shell until it abuts against the outer circumferential surface of the fixing ring, thereby covering the air inlet hole on the left side. After rotating the annular shell, a little of the air inlet hole can be exposed, so that the air intake volume on the left side can be changed to ensure the uniformity of debinding.

[0024] a degumming furnace air duct of the present utility model includes a degumming furnace body 1, a fixing ring 2 is installed outside the degumming furnace body 1, a plurality of air inlet holes 7 penetrating through the degumming furnace body 1 and the fixing ring 2 are provided on four inner surfaces of the degumming furnace body 1, an annular shell 3 is sleeved outside the fixing ring 2, a plurality of assembly ports 11 are arranged in an annular structure on the outer circumferential surface of the annular shell 3, a blocking plate 4 is arranged in each assembly port 11, and an air inlet pipe 6 is vertically installed on the top of the annular shell 3;

[0025] Among them, the air inlet pipe can be connected to a blower outside through a hose.

[0026] In this embodiment, a positioning groove 10 in an annular structure is provided on the outer circumferential surface of the fixing ring 2, a positioning ring is installed on the inner circumferential surface of the annular shell 3 corresponding to the positioning groove 10, the positioning ring is movably arranged in the positioning groove 10, the annular shell can be positioned through the positioning ring and the positioning groove, the front and back movement of the annular shell is avoided, the stability after installation is increased, and the annular shell can only rotate along the positioning groove.

[0027] Among them, the sealing performance between the blocking plate and the assembly port is increased through the rubber layer, and the leakage of gas is avoided.

[0028] In this embodiment, a plurality of support columns 8 are vertically installed on the bottom surface of the degumming furnace body 1, and a bottom plate 9 is installed at the lower ends of the plurality of support columns 8.

[0029] In this embodiment, the width of the blocking plate 4 matches the width of the inner cavity of the annular shell 3, and both ends of the blocking plate 4 are set to abut against the side of the inner part of the annular shell 3, thereby increasing the friction between the blocking plate and the assembly port, and the moved blocking plate can be frictionally positioned through friction.

[0030] In this embodiment, the fixing ring 2 and the annular shell 3 are both made of metal materials, which increases the firmness between the fixing ring and the annular shell.

[0031] In this embodiment, the inner ring surface of the annular shell 3 is tightly fitted with the outer ring surface of the fixing ring 2, which increases the sealing between the annular shell and the fixing ring, and the friction energy between the annular shell and the fixing ring can be used to frictionally position the rotating annular shell.

[0032] A binder removal furnace comprises the binder removal furnace air duct.

[0033] When in use, the objects can be placed inside the debinding furnace body. Before the objects are placed in, the glue content at different positions on the objects can be checked. For example, if the glue content on the left side of the objects is less or there is no glue, the blocking plate on the left side can be pushed inward so that the blocking plate can enter the annular shell until it contacts the outer ring surface of the fixed ring. The air inlet on the left side can be covered by multiple blocking plates, so that the air inlet on the left side cannot be exhausted. After rotating the annular shell, the annular shell can drive the blocking plate so that the blocking plate is slightly misaligned with the air inlet, which can cause the air inlet to leak a little, thereby changing the air intake on the left side to ensure the uniformity of debinding.
