Technical Field
[0001] This utility model relates to the field of quick roller replacement technology, specifically a quick roller replacement structure for a double-roll crusher. Background Technology
[0002] Double roll crushers, a type of mining machinery, are mainly used for crushing ores. These machines are characterized by their small size, large crushing ratio, low noise, simple structure, and convenient maintenance. They produce materials with uniform particle size, low over-crushing rate, and are easy to maintain. They also feature sensitive overload protection and high safety and reliability. The toothed roll crusher has a large crushing capacity. The motor and reducer are connected by a distance-limiting hydraulic coupling to prevent power overload. Sensor overload protection ensures safety and reliability. The toothed roll spacing is hydraulically adjustable, and the toothed roll bearings are centrally lubricated. Optimized tooth profile design allows for selective crushing based on tensile and shear forces, resulting in high efficiency, low consumption, and uniform particle size output.
[0003] Replacing the crushing rollers of a traditional double roll crusher involves a large workload of disassembly and installation, requiring long downtime, which affects the continuity of production and reduces the uptime of the production line and the efficiency of the equipment. Utility Model Content

Traditional double roll crushers require a large amount of work for disassembling and installing the crushing rollers, which requires long-term downtime, affecting the continuity of production and reducing the uptime and efficiency of the production line. Therefore, a quick roller replacement structure for a double roll crusher is proposed.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a quick-change roller structure for a double-roll crusher, comprising a support arm, a support arm base fixedly connected to the bottom of the support arm, a sliding rail fixedly connected to the top of the support arm, a fixed side plate fixedly connected to the side of the sliding rail, a fixing screw fixedly connected to the top surface of the fixed side plate, a robotic arm fixedly connected to the bottom of the fixed side plate, a mechanical joint rotatably connected to the top of the robotic arm, a clamping mechanism provided on the side of the robotic arm, a clamping plate provided on the side of the clamping mechanism, and a top [unclear - possibly a component or mechanism] fixedly connected between the sliding rails. The top support plate has an adjusting cylinder fixedly connected to its bottom. A rotating screw is rotatably connected to the bottom of the adjusting cylinder. A screw sleeve is fitted onto the surface of the rotating screw. A crusher housing is slidably connected to the inner side of the support arm. A shaft end connection hole is provided on the side of the crusher housing. A track groove is provided at the center of the sliding track. A first and second screw rods are rotatably connected to the inner side of the track groove. A T-shaped slider is fixedly connected to the top of the support arm. A screw hole is provided on the side of the T-shaped slider. A support arm groove is provided on the side of the support arm. A transmission motor is fixedly connected to the side of the sliding track.
[0006] Preferably, there are four support arm bases, which are fixedly connected to the bottom of the support arm at diagonal positions on both sides. The sliding rail is fixedly connected to the top center of the support arm. There are four fixed side plates, which are fixed in pairs and symmetrically fixedly connected to both sides of the sliding rail.
[0007] Preferably, there are four robotic arms, arranged in pairs, symmetrically connected to the bottom center of the fixed side plates on both sides of the sliding track. The robotic arms and mechanical joints together form a robotic arm mechanism, and the clamping plates are mechanically connected to the inside of the clamping mechanism in pairs.
[0008] Preferably, there are two top support plates, which are fixedly connected between two sliding rails. An adjusting cylinder is fixedly connected to the bottom center position of the top support plate, and a rotating screw is rotatably connected to the bottom center position of the adjusting cylinder.

[0011] Compared with the prior art, the beneficial effects of this utility model are: This invention relates to a quick-change roller structure for a double-roll crusher. During daily use, the operator first starts the transmission motor, and the robotic arm begins to remove the screws and other components from the shaft ends of the crusher rollers. Since the crusher housing is connected by meshing screws on both sides, after the components are removed, the first and second screw rods begin to rotate counterclockwise, causing the support arms to separate outwards. Simultaneously, the operator activates the adjusting cylinder, causing the rotating screw to rotate. The rotating screw drives the screw sleeve to move up and down, lifting the crusher housing. At this point, the operator can remove the crusher rollers. The adjusting cylinder then drives the rotating screw to rotate, causing the screw sleeve to move downwards, lowering the crusher housing. The operator then inserts the rollers, and the robotic arm installs the screws and other components from the shaft ends. The transmission motor then drives the first and second screw rods to rotate, moving the crusher housing inwards until the meshing connection is complete. This device uses a crusher housing that is easy to disassemble. Automated disassembly and assembly significantly reduces the time required to install the rollers, lowers the cost of manual disassembly, and improves production efficiency.
