DETAILED DESCRIPTION OF THE EMBODIMENTS

[0017] The following further describes the specific embodiments of the present utility model with reference to the drawings. It should be noted here that the description of these embodiments is for helping to understand the present utility model, but does not constitute a limitation to the present utility model. In addition, the technical features involved in the various embodiments of the present utility model described below can be combined with each other as long as they do not conflict with each other.

[0018] As Figures 1-4 shown, a sealed dust-proof transmission device includes an oil groove 1, an angle steel 2, a base 4 and a face cover 5. The oil groove 1, the angle steel 2, the base 4 and the face cover 5 are sequentially connected to form a sealing cavity, and transmission teeth 6 are arranged in the sealing cavity;

[0019] A sealing rubber strip 3 is arranged on one side of the oil groove 1 close to the angle steel 2. The sealing rubber strip 3 extends along the length direction of the oil groove 1, and the sealing rubber strip 3 abuts against the angle steel 2.

[0020] In the sealed dust-proof transmission device, by forming a structure of a sealed cavity and arranging the transmission teeth 6 in the sealed cavity, dust can be prevented from entering the sealed cavity. At the connection position near the rotation of the transmission teeth 6, by arranging a high-temperature-resistant sealing strip 3, the sealing degree between the angle steel 2 and the oil groove 1 can be further improved, ensuring that dust does not enter the sealed cavity, thereby reducing the influence of dust on the transmission teeth 6.

[0021] Preferably, the oil groove 1 includes a front edge 11, a groove body 12, and a rear edge 13 connected in sequence. The groove body 12 is located at the bottom side of the sealed cavity, the front edge 11 is located at the front side of the sealed cavity, the rear edge 13 is located at the rear side of the sealed cavity, the height of the front edge 11 is lower than the height of the rear edge 13, and the rear edge 13 extends upward to the top side of the sealed cavity and is connected to the face cover 5 located at the top side of the sealed cavity. The angle steel 2 and the base 4 are both arranged between the face cover 5 and the front edge 11. Through the rear edge 13, the sealing performance of the rear side of the sealed cavity is ensured. Through the cooperation of the front edge 11, the groove body 12, and the rear edge 13, a groove shape is formed at the bottom side of the sealed cavity to store lubricating oil; since the front edge 11 is lower than the rear edge 13, there is a position to arrange the angle steel 2 and the base 4, thus facilitating the installation of the transmission teeth 6.

[0022] Optionally, an installation bevel 14 is provided on one side of the front edge 11 close to the angle steel 2. The installation bevel 14 inclines upward towards the sealed cavity. An installation slit 31 is provided at the end of the sealing strip 3, and the installation bevel 14 is inserted into the installation slit 31. Such a setting is used to increase the friction between the sealing strip 3 and the angle steel 2, thereby improving the sealing degree. By providing the installation slit 31 on the sealing strip 3, the sealing strip 3 can be conveniently disassembled, thus facilitating the replacement of the sealing strip 3.

[0023] Specifically, a rotating shaft 7 is provided in the base 4. One end of the rotating shaft 7 extends into the sealed cavity and is fixedly connected to the transmission teeth 6. The other end of the rotating shaft 7 passes through the base 4 and is connected to a roller sleeve 8, so that when the transmission teeth 6 rotate, the roller sleeve 8 is driven to rotate through the rotating shaft 7. The rotating shaft 7 penetrates through the base 4 and thus extends from the sealed cavity to the outside of the sealed cavity. The roller sleeve 8 is used to install a roller shaft, so that the roller shaft can be driven to rotate by the transmission teeth 6.

[0024] Preferably, a transmission gearbox 9 is provided on the rear edge 13 of the oil groove 1. The transmission gearbox 9 is in transmission connection with the transmission teeth 6 located in the sealed cavity. The transmission gearbox 9 can drive the transmission teeth 6 to rotate, and the transmission gearbox 9 is a power source. The face cover 5 is of a detachable structure. After removing the face cover 5, the transmission teeth 6 in the sealed cavity can be maintained.

[0025] It should be noted that the angle steel 2 is of an L-shaped structure. One end of the angle steel 2 is connected to the base 4 and abuts against the sealing strip 3, and the other end of the angle steel 2 extends outward from the sealing cavity to serve as an installation surface. A plurality of screw holes are provided on the installation surface, and the screw holes cooperate with screws, and the sealing and dust-proof transmission device can be suspended on the side wall of the ceramic conveying line through the installation surface.

[0026] The above has described in detail the embodiments of the present invention in conjunction with the accompanying drawings, but the present invention is not limited to the described embodiments. For those skilled in the art, without departing from the principle and spirit of the present invention, various changes, modifications, substitutions, and variations made to these embodiments still fall within the protection scope of the present invention.
