Technical Field

[0001] This utility model relates to the field of metal powder screening technology, and in particular to a metal powder screening machine that is not prone to screen clogging. Background Technology

[0002] A metal powder screening machine is a specialized device for particle size classification and screening of metal powders. Utilizing principles such as vibration and ultrasound, the machine causes the metal powder to reciprocate across the screen surface. By passing the powder through screens of different mesh sizes, it separates the powders according to particle size, thus obtaining metal powder products with varying particle size ranges to meet the precise particle size requirements of various industrial production and scientific research. Metal powder screening machines are widely used in industries such as powder metallurgy and metal raw materials.

[0003] Existing metal powder screening machines typically include linear vibrating screens. Linear vibrating screens utilize a vibrating motor or other vibration source to generate linear vibration, causing the metal powder to move linearly across the screen surface, thus achieving screening. Linear vibrating screens are characterized by large processing capacity and high screening efficiency, making them suitable for screening large quantities of metal powder.

[0004] When using existing metal powder screening machines, due to the large quantity of metal powder, some particles are prone to clogging the screen during linear screening, thus affecting the stability and efficiency of vibrating screening. Utility Model Content

[0009] Preferably, two limit rods are symmetrically inserted into the side wall of the frame near the cylinder, and two sliding grooves are opened on the side wall of the mounting base for the limit rods to slide, which improves the stability of the movement of the mounting base.

[0022] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0023] A metal powder screening machine is a specialized device for particle size classification and screening of metal powders. Metal powders have wide applications in numerous fields, such as powder metallurgy: by pressing metal powders into shapes and then performing processes like sintering, various mechanical parts, such as gears, bushings, and cams, are manufactured. This method can produce parts with complex shapes and high precision, while also achieving high material utilization and effectively reducing costs. Metal coatings: applying metal powders to the surface of objects through methods such as spraying and electroplating can improve the object's corrosion resistance, wear resistance, and electrical conductivity. For example, in industries such as automobiles and shipbuilding, metal powder coatings are commonly used to protect metal components from environmental corrosion.

[0024] Linear vibrating screens are a common type of equipment used for screening metal powders. They utilize a vibrating motor or other vibration source to generate linear vibration, causing the metal powder to move linearly across the screen, thus achieving screening. Linear vibrating screens are characterized by large processing capacity and high screening efficiency, making them suitable for screening large quantities of metal powders.

[0025] Example 1

[0026] Please refer to Figures 1-5A metal powder screening machine that is not prone to screen clogging includes a frame 1, a vibrating motor 2, and a base 3. The vibrating motor 2 is fixed to the bottom end of the frame 1 by bolts. Starting the vibrating motor 2 causes the frame 1 to vibrate. Several springs 4 are fixed to the top of the base 3, with the tops of the springs 4 all fixed to the bottom end of the frame 1. The springs 4 are symmetrically distributed, and a damper is inserted in the middle of each spring 4. The bottom end of the damper is fixed to the top of the base 3, and the top end of the damper is fixed to the bottom end of the frame 1. The springs 4 and the dampers work together to improve the overall stability of the frame 1's vibration through compression deformation. The base 3 is made of cast iron and is used for support and limiting. A cover plate 6 is rotatably connected to the top of the frame 1 via a hinge, allowing for easy rotation of the cover plate 6. The operator inspects the inside of the frame 1. A blower 8 is fixed to the top of the cover plate 6 by bolts. A cylinder 7 is fixed to the side wall of the frame 1 by bolts. The output end of the cylinder 7 passes through the frame 1 and is fixed to the mounting base 13 by a coupling. A filter screen 12 is clamped on the inner side wall of the frame 1. The filter screen 12 is obliquely distributed and parallel to the inner bottom of the frame 1, thereby improving the convenience of linear powder screening. Two brushes 14 are woven at the bottom of the mounting base 13. An air duct 16 is clamped at the bottom of the mounting base 13 near the brushes 14. Several nozzles 18 are inserted into the bottom of the air duct 16. A flexible hose 15 is inserted into the air inlet at the top of the blower 8. The other end of the flexible hose 15 passes through the cover plate 6 and is inserted into the side wall of the air duct 16.

[0027] The brush 14 is adapted to the external dimensions of the filter screen 12, and the bottom end of the brush 14 is parallel to the surface of the filter screen 12, which improves the stability of cleaning.

[0028] A feed hopper 5 is inserted into the top of the frame 1. The feed hopper 5 is funnel-shaped. A first discharge hopper 9 is fixed at the bottom of the frame 1. A second discharge hopper 10 is fixed at the top of the frame 1 near the first discharge hopper 9. The first discharge hopper 9 is U-shaped and connected to the inner bottom of the frame 1. The inner bottom of the second discharge hopper is parallel to the filter screen 12, which improves the stability of powder receiving.

[0029] When using this metal powder screening machine, the operator first connects an external power supply and pours the metal powder to be screened from the feed hopper 5 into the inside of the frame 1. Then, the vibrating motor 2 is started to drive the frame 1 to vibrate at a high frequency. Under the action of gravity and vibration, the metal powder moves linearly along the filter screen 12. Metal powder that meets the standard falls into the bottom of the frame 1 through the limit rod 11 and is finally discharged through the bottom of the first discharge hopper 9 to complete the collection. Large particles of metal powder are trapped on the surface of the limit rod 11. When a large number of metal particles accumulate and jam during the brushing process, causing the mesh to become blocked and affecting the stability and efficiency of the limit rod 11 screening, the operator starts the cylinder 7 to drive the mounting base 13 to move horizontally, thereby pushing the brush 14 to clean the surface of the filter screen 12 and increase the fluidity of the accumulated powder. Then, the blower 8 is started to generate wind to blow the surface of the filter screen 12, thereby improving the efficiency and quality of cleaning the surface of the filter screen 12. At the same time, the wind can blow the brush 14 to reduce the accumulation of powder and improve the convenience of cleaning the brush 14, thus facilitating the continuous operation of the brush 14.

[0030] Example 2

[0031] Two limit rods 11 are symmetrically inserted into the side wall of the frame 1 near the cylinder 7. Two sliding grooves 17 are opened on the side wall of the mounting base 13 for the limit rods 11 to slide, which improves the stability of the movement of the mounting base 13.

[0032] When the mounting base 13 moves horizontally, the limiting rod 11 slides in sequence inside the slide groove 17 to limit the lateral displacement at both ends of the mounting base 13, thereby improving the stability of the brush 14 as it moves horizontally with the mounting base 13 for cleaning.

[0033] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
