Description

Technical Field

[0001] This utility model relates to the field of roller sand making machine technology, specifically a sealing structure for a double roller sand making machine. Background Technology

[0002] Double roller crushing machines, also known as twin roller crushing machines, can be used to crush medium-hardness materials in industries such as cement, chemical, power, and refractory materials. They are widely used in industries such as sand making, mineral processing, cement, metallurgy, chemical, and building materials.

[0003] A sealing structure is required during the operation of a double-roll crusher. This sealing structure is primarily annular, fitted around the outer circumference of the support roller. It includes a fixing part and a sealing part. The fixing part is equipped with fasteners to secure it to the support roller. The sealing part extends in a funnel shape from the side of the fixing part near the bearing housing towards the bearing housing. When the extended end of the sealing part abuts against the bearing housing, it expands and deforms outwards to tightly seal the gap between the support roller and the bearing housing. This design effectively prevents rolling oil or foreign matter from entering the bearing housing's shaft hole and prevents the contact surface between the support roller and the bearing housing from detaching, thus reducing production costs. However, it does not seal the feed inlet of the double-roll crusher, causing dust generated inside the crusher to escape from the feed inlet during operation. This makes sealing inconvenient for the user and negatively impacts the surrounding environment. Utility Model Content

[0021] As a technical optimization of this utility model, by setting a bearing sealing mechanism 2, the bearing housing in the sand making machine 104 can be sealed. The user rotates the rotating shaft 22, which drives the rotating disk 23 to rotate. The rotating disk 23 drives the connecting shaft 24 to rotate. The connecting shaft 24 drives the transmission frame 25 to move inward. The transmission frame 25 drives the moving plate 26 to move inward. The moving plate 26 drives the clamping plate 27 to move inward, while compressing the connecting spring 7. Then, the sealing shell 21 is inserted into the sand making machine 104. Then, the rotating shaft 22 is released, and the moving plate 26 is driven to move outward by the connecting spring 7. The moving plate 26 drives the clamping plate 27 to reset and insert into the sand making machine 104, thus fixing the bearing sealing mechanism 2 and preventing the bearing sealing mechanism 2 from shaking. The bearing housing is sealed by the bearing sealing mechanism 2.

[0022] refer to Figure 1 The protective enclosure 101 has four fixed legs 4 at the bottom corners, and the bottom of the legs 4 is fixedly connected to a fixing plate 5.

[0025] As a technical optimization of this utility model, by setting a fixed bearing 6, the rotating shaft 22 can be fixed to prevent the rotating shaft 22 from shaking when moving.

[0026] refer to Figure 3 A connecting spring 7 is fixedly connected to the inner side of the movable plate 26, and a connecting plate 8 is fixedly connected to the inner side of the connecting spring 7. The surface of the connecting plate 8 is fixedly connected to the inside of the sealing shell 21. Slider 9 is fixedly connected to the top and bottom of the movable plate 26. Slide grooves 10 are provided on both sides of the top and bottom of the inner wall of the sealing shell 21. The slider 9 is slidably connected to the slide grooves 10.

[0027] As a technical optimization of this utility model, by setting the connecting spring 7 and the connecting plate 8, the movable plate 26 can be reset, thereby facilitating user use. By setting the slider 9 and the slide groove 10, the movable plate 26 can be guided to prevent the movable plate 26 from deviating during movement.

[0028] The working principle and usage process of this utility model are as follows: During use, the user rotates the rotating shaft 22, which drives the rotating disk 23 to rotate. The rotating disk 23 drives the connecting shaft 24 to rotate, which in turn drives the transmission frame 25 to move inward. The transmission frame 25 then drives the moving plate 26 to move inward, and the moving plate 26 drives the clamping plate 27 to move inward. Simultaneously, the connecting spring 7 is compressed. Then, the sealing shell 21 is inserted into the sand making machine 104. Afterward, the rotating shaft 22 is released, and the connecting spring 7 drives the moving plate 26 to move outward. The moving plate 26 then drives the clamping plate 27 to reset and insert into the sand making machine 104, thus fixing the bearing sealing mechanism 2 and preventing it from shaking. The bearing sealing mechanism 2 seals the bearing housing. The raw material is then poured into the feed hopper 105. The weight of the raw material pushes the cover plate 31 open, and the cover plate 31 drives the connecting block 32 to move downward. The connecting block 32 drives the fixing plate 33 to move downward. The fixing plate 33 compresses the fixing spring 34, and the fixing plate 35 and the fixing plate 33 compress the fixing spring 34. When the raw material is completely inside the feed hopper 105, the feed hopper 105 guides the raw material into the sand making machine 104. At the same time, when there is no item on the top of the cover plate 31, the fixing spring 34 drives the fixing plate 33 to reset, the fixing plate 33 drives the connecting block 32 to reset, and the connecting block 32 drives the cover plate 31 to reset. The cover plate 31 seals the feed hopper 105 to prevent dust generated during the processing of raw materials by the sand making machine 104 from escaping.

[0029] In summary, the sealing structure of this double-roll crusher, through the cover sealing mechanism 3, can seal the feed hopper 105 to prevent dust inside the crusher 104 from drifting out and polluting the surrounding environment. Furthermore, the bearing sealing mechanism 2 seals the bearing housing of the crusher 104, ensuring that dust generated inside the double-roll crusher during use will not drift out from the feed inlet, facilitating sealing by the user and thus protecting the environment around the double-roll crusher.
