[0001] The present invention relates to the technical field of NdFeB magnet production, and more specifically to a crushing and screening integrated device for producing NdFeB magnets. Background Art

[0002] In the production process of NdFeB magnets, crushing and screening are two indispensable steps. The crushing step is used to crush the block or granular raw materials into smaller particles for subsequent processing. The screening step is used to screen out the materials that do not meet the specified particle size in the crushed materials to ensure the uniformity of the particle size.

[0003] However, most of the crushing and screening equipment on the market currently adopts a separate design, that is, the crusher and the screen exist as two independent devices. This design has many disadvantages. First, since the two devices occupy a certain space respectively, the overall floor space is large, which is not conducive to the compact layout and efficient operation of the production line. Secondly, the two devices need to be equipped with corresponding power systems and control systems respectively, resulting in higher overall costs. In addition, the material transfer process between the two devices may also lead to increased energy consumption and reduced efficiency.

[0004] Therefore, in view of this, the existing structure and deficiencies are studied and improved, and an integrated crushing and screening equipment for the production of NdFeB magnets is provided, in order to achieve a more practical purpose. Summary of the invention

[0005] In order to overcome the above-mentioned defects of the prior art, the present invention provides an integrated crushing and screening device for the production of NdFeB magnets to solve the problems existing in the above-mentioned background technology.

DETAILED DESCRIPTION

[0024] The technical solution of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the present invention.

[0025] Embodiment 1: The present invention provides an innovative integrated crushing and screening equipment for the production of NdFeB magnets, aiming to simplify the production process, improve production efficiency, and reduce energy consumption. The equipment integrates the two functions of crushing and screening, and achieves efficient and convenient material processing through optimized design.

[0026] The main body 100 of the equipment is the core of the whole system, which consists of two parts: a crushing box 110 and a screening box 111. Two key components, crushing rollers 112, are arranged in the crushing box 110. The two crushing rollers are driven to rotate by their own independent motor bodies 115, ensuring the stability and efficiency of the crushing process. The design of the crushing rollers fully considers the physical properties of the NdFeB magnets, and can effectively crush raw materials of different hardness and size, providing a good material basis for subsequent screening work.

[0027] In order to facilitate the input and maintenance of materials, a removable top plate 113 is specially installed on the top of the crushing box 110. The design of the top plate is not only easy to replace and clean, but also realizes efficient introduction of materials through the feed port 114 on it. The size and shape of the feed port are precisely calculated to ensure that the material can enter the crushing box smoothly, while avoiding blockage or damage to the equipment caused by oversized or undersized materials.

[0028] The screening box 111 is closely connected with the crushing box 110, realizing seamless transmission of materials. A screening cylinder 116 is arranged inside the screening box, and a screen 117 is detachably installed inside the cylinder. The design of the screen takes full account of the screening efficiency and accuracy, and can be easily replaced according to different particle size requirements, meeting the strict control of material particle size in the production of NdFeB magnets. A removable collection box 118 is arranged at the bottom of the screening box, which is convenient for collecting the screened materials, and also facilitates the subsequent cleaning and transportation work. Example

[0029] On the basis of the first embodiment, the second embodiment further improves the automation degree and screening efficiency of the equipment, making it more adaptable to the needs of modern NdFeB magnet production lines.

[0030] First, a vibration motor 131 is installed on the outer wall of the screening box 111. This design allows the screen 117 to vibrate and screen under the action of the vibration motor, effectively improving the screening efficiency and accuracy. Vibration screening can not only speed up the screening speed of materials, but also reduce the accumulation and clogging of materials on the screen, ensuring the continuity and stability of the screening process.

[0031] Secondly, an adjustment mechanism is added to the crushing box 110, which includes a movable groove 122 and an electric telescopic rod 123. The movable groove provides the necessary movable space for the crushing roller, while the electric telescopic rod is fixed to the outside of the crushing box through a mounting column, and its output end is connected to the motor body. Through the telescopic action of the electric telescopic rod, the distance between the two crushing rollers can be accurately adjusted to meet the crushing needs of different raw materials and particle size requirements. This design not only improves the flexibility of the equipment, but also reduces the labor intensity of manual adjustment.

[0032] In order to further enhance the stability and accuracy of the adjustment mechanism, a guide assembly is also provided. The guide assembly includes a guide slide 124 and a guide sleeve 125. The guide slide is installed on the outer wall of the crushing box, and the number is at least one, which ensures the smooth movement of the crushing roller during the adjustment process. The guide sleeve is connected to the end of the crushing roller and is slidably installed in the guide slide, providing the necessary guiding function. This design effectively prevents the crushing roller from deflecting and jamming during the adjustment process, and ensures the continuity and stability of the crushing process.

[0033] The screening box 111 is also provided with an automatic discharging mechanism, which includes an electric push rod 126, a push plate 127, an inclined guide plate 128, a through slot 129 and an electric door 130. The through slot is provided on the screening cylinder to facilitate the discharge of materials that do not meet the particle size requirements. The inclined guide plate is installed on the outer wall of the screening box to guide these materials to be discharged smoothly from the equipment. The electric door is used to control the opening and closing of the through slot to ensure the controllability and accuracy of material discharge. The electric push rod is fixed to the screening box through a support, and its output end is connected to the push plate. When the material needs to be discharged, the electric push rod pushes the push plate to push the material on the top of the screen onto the inclined guide plate for discharge, thereby realizing an automated discharging process.

[0034] In addition, the design of the feed port 114 has been further optimized. A sealing baffle 119 is installed inside the feed port through a rotating shaft to ensure the sealing of the material when it is put in. At the same time, the feed port is designed in a 7-shaped shape with an angle of 120°. The sealing baffle uses gravity to ensure the convenience of feeding while also having a good sealing effect. This design effectively avoids leakage and dusting of materials during the feeding process, and improves the environmental performance of the equipment.

[0035] In order to further reduce the dust problem during the production process, the main body 100 of the equipment is also specially equipped with a dust reduction mechanism. The mechanism includes a bracket 120 and an atomizing nozzle 121. The bracket is fixed on the outer wall of the crushing box, and the atomizing nozzle is fixed on the top of the bracket. By spraying water mist at the feed inlet, the atomizing nozzle effectively reduces the dust phenomenon when the material is put into the material, and improves the production environment. At the same time, the water pipe connected to the end of the atomizing nozzle ensures the continuous supply and stable spraying of water mist.

[0036] Finally, the equipment body 100 also includes an advanced control system. The system realizes the automatic operation and monitoring of the equipment by centrally controlling the start, stop and adjustment of the motor body, vibration motor, electric telescopic rod, electric door and electric push rod. The control system not only improves the operating efficiency of the equipment, but also reduces the complexity and labor intensity of manual operation. At the same time, by real-time monitoring of the operating status and parameter changes of the equipment, the control system can promptly discover and handle potential faults and problems, ensuring the stable operation and safe production of the equipment.

[0037] In summary, the integrated crushing and screening equipment for NdFeB magnet production provided by the present invention realizes efficient, convenient and environmentally friendly material processing through optimized design and design. The equipment not only improves production efficiency and quality stability, but also reduces energy consumption and labor intensity, providing strong support for the modernization and upgrading of NdFeB magnet production lines.
