[0002] A double-roller sand making machine is a mechanical device used for crushing and grinding materials, widely used in industries such as mining, construction, and the chemical industry. This equipment primarily uses two counter-rotating rollers to squeeze and crush materials to achieve the desired particle size. After a period of use, the roller skins can become damaged to some extent. Currently, when damage does not reach the required replacement standard, the roller skins are typically repaired using cutting tools. However, existing repair procedures typically require disassembly of the rollers, a time-consuming and labor-intensive process that results in low repair efficiency. Therefore, a double-roller sand making machine was proposed to address this issue. Utility Model Content

[0003] The main purpose of the utility model is to provide a roller sand making device to solve the problem that the existing cutting and repair work usually requires the rollers to be disassembled before being carried out, which is a time-consuming and labor-intensive process and leads to low repair efficiency.

[0004] In order to solve the above technical problems, the technical solution adopted by the utility model is: a double-roller sand-making equipment, comprising a double-roller sand-making machine and two rollers arranged in the double-roller sand-making machine, and roller skin repair mechanisms are symmetrically arranged on both sides of the double-roller sand-making machine for repairing the corresponding rollers, wherein the roller skin repair mechanism comprises a storage box fixed on the side of the double-roller sand-making machine and parallel to the rollers, and a telescopic opening is provided between the storage box and the double-roller sand-making machine to connect the two, and a longitudinal spacing adjustment mechanism is provided on the inner bottom wall of the storage box, and a transverse adjustment mechanism is provided on the transmission of the longitudinal spacing adjustment mechanism, and a cutting assembly is provided on the transmission of the transverse adjustment mechanism. The cutting assembly can pass through the telescopic opening and contact with the rotating roller under the adjustment of the longitudinal spacing adjustment mechanism, and transversely cut the roller through the adjustment of the transverse adjustment mechanism.

[0005] In the preferred embodiment, the longitudinal spacing adjustment mechanism includes two fixed limit slides and a rotatable screw. The limit slides and the screw are arranged in the storage box perpendicular to the roller. A drive motor with an output end connected to the screw is fixed on the outside of the storage box.

[0006] In the preferred embodiment, the lateral adjustment mechanism is a linear movable slide, and a threaded sleeve and two sliding sleeves are provided at the bottom of the linear movable slide, wherein the threaded sleeve is threadedly mounted on the outside of the screw, and the two sliding sleeves are respectively slidably mounted on the outside of the two limiting slides, and the cutting assembly is installed on the sliding platform of the linear movable slide.

[0007] In a preferred embodiment, the cutting assembly includes a turning tool mounting seat mounted on a sliding table of the linear movable slide, and a cutting tool with a tool head facing the roller is mounted on the cutting tool mounting seat.

[0008] In a preferred embodiment, a laser rangefinder is further provided on the sliding table of the linear movable slide, and a measuring end of the laser rangefinder and a cutting head of the cutting knife are located on the same axis of the roller.

[0009] In a preferred embodiment, an air inlet slot corresponding to the telescopic opening is further provided on the back of the storage box, and an air inlet assembly is installed at the air inlet slot.

[0010] In a preferred embodiment, the air inlet assembly includes an air guide cover installed at the air inlet slot, and the back side of the air guide cover is connected to an air inlet tube for connecting to the fan duct.

[0012] The utility model provides a double-roller sand-making equipment. By symmetrically arranging roller skin repair mechanisms corresponding to the two rollers on both sides of the double-roller sand-making machine, when the roller skin needs to be repaired, the longitudinal spacing adjustment mechanism of the roller skin repair mechanism is utilized to transport the cutting component to contact with the rotating roller, and the roller is used to cut and repair it by its own rotation. At the same time, under the action of the transverse adjustment mechanism, the cutting component is driven to perform comprehensive cutting and repair on the roller, thereby avoiding the need to remove the rotor for repair and greatly improving the repair efficiency. When repair is not needed, the cutting component can be stored in the storage box, thereby not affecting the normal operation of the double-roller sand-making machine. In addition, by arranging the air inlet component, an outward blowing airflow can be formed in the roller skin repair mechanism to avoid debris from entering it. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] In the preferred embodiment, the longitudinal spacing adjustment mechanism 302 includes two limit slides 3020 and a screw 3021. The limit slides 3020 and the screw 3021 are both arranged in the storage box 301 perpendicular to the roller 2. The limit slide 3020 is fixed in the storage box 301. The screw 3021 is rotatably arranged in the storage box 301 through a bearing and is located between the two limit slides 3020. A drive motor 3022 is fixed on the outside of the storage box 301, and the output end is transmission-connected to the screw 3021.

[0022] In the preferred embodiment, the lateral adjustment mechanism 303 is a linear movable slide 3030, the bottom of which is provided with a threaded sleeve 3031 and two sliding sleeves 3032, wherein the threaded sleeve 3031 is threadedly mounted on the outside of the screw 3021, and the two sliding sleeves 3032 are respectively slidably mounted on the outside of the two limiting slides 3020, and the cutting assembly 304 is installed on the sliding platform of the linear movable slide 3030.

[0023] During use, the screw 3021 is driven to rotate by the driving motor 3022, so that the threaded sleeve 3031 outside the screw 3021 is used to make the lateral adjustment mechanism 303 move longitudinally under the sliding sleeve 3032 and the limiting slide 3020, so that the cutting assembly 304 passes through the telescopic opening 3010 and contacts the corresponding roller 2. In addition, by installing the cutting assembly 304 on the sliding table of the linear movable slide 3030, the cutting assembly 304 can be driven by the linear movable slide 3030 to move along the axial direction of the roller 2, thereby comprehensively repairing the roller 2.

[0024] It should be noted that the moving length of the sliding table of the linear movable slide 3030 should meet the axial length of the roller skin of roller 2, and the linear movable slide 3030 is a mature existing technology, so it will not be described in detail.

[0025] In this embodiment, the sliding sleeve 3032 and the threaded sleeve 3031 are both fixed to the bottom of the linear movable slide 3030 by screws.
