Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts belong to the scope of protection of the present utility model.

[0027] Please refer to Figures 1-4 , the present utility model provides a technical solution for a sealed double-roll machine: a sealed double-roll machine includes a device main body 1. The device main body 1 includes: a housing 11. A blanking box 12 is fixedly connected to the bottom end of the housing 11. A feed inlet 13 is opened at the top end of the housing 11. First linear slide rails 14 are fixedly connected to the front and rear ends of the feed inlet 13. By providing the first linear slide rails 14, a gate plate 16, a handle 17, and a compression nut 18, when it is necessary to control the feed amount, the gate plate 16 is moved to one side by using the handle 17 so that the limit hole of the gate plate 16 is offset from the feed inlet 13, thereby controlling the feed amount, adjusting the size of the feed amount, and preventing ore blockage in the double-roll cavity. Then, the gate plate 16 is pressed down by using the compression nut 18 for easy fixing. The operation is simple and convenient. A feed hopper 15 is fixedly connected to the top end of the linear slide rail. A gate plate 16 is slidably connected to the middle of the linear slide rail. One end of the gate plate 16 is fixedly connected to a handle 17. A compression nut 18 is threadedly connected to the top end of the linear slide rail. Second linear slide rails 19 are fixedly connected to the front and rear inner walls of the housing 11. Two limit plates 101 are slidably connected to the middle of the second linear slide rails 19. A connecting shaft 102 is rotatably connected to the middle of the limit plate 101. A roller is fixedly connected to the middle of the connecting shaft 102;

[0028] One end of the connecting shaft 102 penetrates through the limiting plate 101. A gear 103 is fixedly connected to one end of the connecting shaft 102. The outer end of the gear 103 is meshed with a belt 104. By setting the belt 104, the gear 103, the tooth shaft 105 and the motor 106, the motor 106 can drive the belt 104 to make the first gear 103 rotate. Since the belt 104 has double-sided tooth grooves, the second gear 103 will also rotate accordingly. Tooth grooves are provided on both the inner and outer walls of the belt 104. One end of the belt 104 is rotatably connected to a tooth shaft 105. The tooth shaft 105 is fixedly connected to the output end of the motor 106. The bottom end of the motor 106 is fixedly connected to a slider 107. By setting the slider 107, the chute 109, the support table 108 and the threaded rod 110, when the gap between the rollers is adjusted, the belt 104 will become loose. Therefore, it is necessary to use the threaded rod 110 to move the slider 107 left and right so that the motor 106 moves left and right to facilitate the adjustment of the tension of the belt 104 and prevent the belt 104 from derailing, which affects the working efficiency and effectively increases the practicability of the device. The left end of the blanking box 12 is fixedly connected to a support table 108. A chute 109 is provided at the top end of the support table 108. The chute 109 is slidably connected to the slider 107 left and right. The left side of the slider 107 is fixedly connected to a threaded rod 110. One end of the threaded rod 110 is threadedly connected to the support table 108. First nuts 111 are fixedly connected to the outer ends of the limiting plates 101 close to the outside. By setting the first nuts 111, the connecting shaft 102, the limiting plates 101 and the second linear slide rail 19, when it is necessary to adjust the gap between the rollers, the first nuts 111 are used to push the limiting plates 101 to move on the second linear slide rail 19, so as to adjust the gap between the two rollers. Through the disc spring 113, a buffering effect is achieved. The outer end of the first nut 111 is fixedly connected to a support plate 112. One end of the limiting plate 101 is fixedly connected to a disc spring 113. The disc spring 113 is fixedly connected to the support plate 112. A collection box 114 is slidably connected to the middle of the blanking box 12. A handle 115 is fixedly connected to the outer end of the collection box 114.

[0029] The utility model adopts a special structural design and uses multiple seals to minimize the outward dispersion of dust in the crushing chamber. Moreover, a dedicated air extraction and dust removal port is reserved in the design. Users can connect the equipment to the air extraction and dust removal system using pipelines for air extraction and dust removal. The outer shell 11 uses multiple seals to minimize the outward dispersion of dust in the crushing chamber. During use, the handle 17 is used to move one side of the gate plate 16 box so that the limit hole of the gate plate 16 is offset from the feed port 13, thereby controlling the feed rate, adjusting the size of the feed amount, and preventing ore blockage in the roll cavity. Then, the pressing nut 18 is used to press the gate plate 16 downward for easy fixation. The operation is simple and convenient. When the gap between the roll wheels needs to be adjusted, the first nut 111 is used to move the limit plate 101 on the second linear slide rail 19. Through the disc spring 113, a buffering effect is achieved. By setting the first nut 111 and rotating the first nut, the roll is horizontally moved, thereby adjusting the gap between the two rolls. When the motor 106 is started to drive the belt 104, the first gear 103 rotates. Since the belt 104 has double-sided tooth grooves, the second gear 103 will also rotate accordingly. After adjusting the gap between the roll wheels, the belt 104 will become loose. Therefore, the threaded rod 110 is used to move the slider 107 left and right, so that the motor 106 can be moved left and right to facilitate the adjustment of the tension of the belt 104 and prevent the belt 104 from derailing and affecting the working efficiency, effectively increasing the practicality of the device.
