[0003] Mining Industry: Vibrating screens are important equipment for classifying solid materials and are widely used in mining, building materials and other industries. Traditional vibrating screens often use cranes to suspend the feed inlet, which is cumbersome and inefficient.

[0004] Printing industry: 3D printing requires a large amount of powder with different particle diameters. Currently, the main method used is vibrating sieving. However, due to the fine particle size of the printing powder and the small sieve holes, conventional vibrating sieving often gets clogged, which restricts the sieving efficiency.

[0005] Tablet manufacturing industry: Tablets are common solid dosage forms that require sieving during production. High-efficiency sieving machines can meet production needs.

[0006] Magnet and alloy powder industry: When preparing magnets and alloy powders, the powders need to be sieved to improve product quality, production efficiency and raw material utilization.

A hollow column is sleeved in the inner cavity of the driven gear. A nozzle is connected to the bottom left side of the hollow column. A brush plate is fixedly connected to the bottom of the nozzle.

[0008] However, the current pipe support with a limiting structure has the following problems: it cannot make the force rod drive the screening plate to move, resulting in the inability to achieve the screening effect and the inability to control the particle size of the material powder. Therefore, we propose a laser fusion powder feeder with screening function. Utility Model Content

[0009] The purpose of this invention is to provide a laser fusion powder feeder with sieving function, which can solve the problem in related technologies that the force rod cannot drive the sieving plate to move, resulting in the inability to achieve the sieving effect and control the particle size of the material powder.

[0010] The specific technical solution adopted by this utility model is as follows:

[0011] A laser cladding powder feeder with sieving function includes a support frame and a body. The body is located on top of the support frame, and a button is provided on the front side of the support frame. A sieving device is provided inside the body. The sieving device includes a fixing plate, which is fixedly connected to the inner wall of the body. A motor is located at the bottom of the fixing plate, and a rotating shaft is fixedly connected to the end of the output shaft of the motor.

[0012] Preferably, a rotating plate is fixedly connected to the circumferential surface of the rotating shaft, a blocking block is fixedly connected to the circumferential surface of the rotating plate, and a force-bearing rod is fixedly connected to the bottom of the screening plate. This design is beneficial for the screening plate to screen materials.

[0013] Preferably, the number of the blocking blocks is set to several, and they are arranged in a circumferential array on the circumferential surface of the rotating plate. One end of the blocking block is set as an arc surface. This design is beneficial to the rotating plate being able to drive the blocking blocks to rotate when it is subjected to force.

[0014] Preferably, the inner wall of the machine body is provided with a feeding device, the feeding device includes a partition plate, the partition plate is fixedly connected to the inner wall of the machine body, the top of the partition plate is provided with a feeding groove, the circumferential surface of the rotating shaft is fixedly connected with an actuating ring, the circumferential surface of the actuating ring is fixedly connected with an actuating rod, and the top of the partition plate is provided with a slot. This design is conducive to the actuating ring rotating under force to drive the actuating rod to rotate.

[0015] Preferably, one end of a force-bearing spring is fixedly connected to the inner wall of the slot, and a baffle is fixedly connected to the end of the force-bearing spring away from the inner wall of the slot. A connecting rod is fixedly connected to the circumferential surface of the actuating ring, and a scraper is fixedly connected to the bottom of the connecting rod. This design facilitates the connecting rod to rotate with the actuating ring under force.

[0016] Preferably, the baffle is slidably connected to the inner wall of the slot, the scraper is slidably connected to the top of the partition, and the scraper is T-shaped. This design allows the scraper to be scraped by applying force to the top of the partition.

When the blocking block is stressed and rotates continuously, it forces the force rod to lose force, thereby driving the screening plate to reset through the elastic force of the spring, thus achieving the screening function and being able to control the particle size of the material powder.

[0020] 2. By setting up an auxiliary device, this utility model enables the scraper to be subjected to force and scrape on the top of the partition plate, and also to contact the arc-shaped surface of the baffle plate, increasing the speed at which the baffle plate intermittently opens the feed chute, and also scraping the material into the inside of the feed chute, so that the material enters the machine body evenly and orderly, ensuring that the screening work of the screening plate can proceed smoothly.

[0028] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.

[0029] like Figure 1-3As shown, a laser cladding powder feeder with sieving function includes a support frame 1 and a body 2. The body 2 is located on top of the support frame 1. A button 3 is provided on the front side of the support frame 1. A sieving device 4 is provided inside the body 2. The sieving device 4 includes a fixing plate 41, which is fixedly connected to the inner wall of the body 2. A motor 42 is provided at the bottom of the fixing plate 41. A rotating shaft 43 is fixedly connected to the end of the output shaft of the motor 42. A rectangular groove 44 is provided on the inner wall of the body 2. One end of a spring 45 is fixedly connected to the inner wall of the rectangular groove 44. A sieving plate 46 is fixedly connected to the end of the spring 45 away from the inner wall of the rectangular groove 44.

[0030] A rotating plate 47 is fixedly connected to the circumferential surface of the rotating shaft 43, a blocking block 48 is fixedly connected to the circumferential surface of the rotating plate 47, and a force-bearing rod 49 is fixedly connected to the bottom of the screening plate 46. This design is beneficial for the screening plate 46 to screen materials.

[0031] The number of the blocking blocks 48 is set to several, and they are arranged in a circular array on the circumferential surface of the rotating plate 47. One end of the blocking block 48 is set as an arc surface. This design is beneficial to the rotating plate 47 being able to drive the blocking blocks 48 to rotate when it is subjected to force.

[0032] According to the above structure, when the staff needs to screen the material, the staff can control the machine body 2 to be powered on by button 3, which forces the motor 42 to start and drive the rotating shaft 43 to rotate. This forces the rotating plate 47 fixed on the circumference of the rotating shaft 43 to rotate, and forces the resistance block 48 to rotate with the rotating plate 47. This causes the resistance block 48 to come into contact with the force rod 49, which forces the force rod 49 to be forced to slide the screening plate 46 upward on the inner wall of the rectangular groove 44. When the resistance block 48 is continuously rotated under force, the force rod 49 is forced to lose force, thereby causing the screening plate 46 to be reset by the elastic force of the spring 45, thus achieving the screening effect and controlling the particle size of the material powder.

[0033] like Figure 4-5 As shown, the inner wall of the machine body 2 is provided with a feeding device 5. The feeding device 5 includes a partition 51, which is fixedly connected to the inner wall of the machine body 2. A feeding groove 52 is opened on the top of the partition 51. An action ring 53 is fixedly connected to the circumferential surface of the rotating shaft 43. An action rod 54 is fixedly connected to the circumferential surface of the action ring 53. A slot 55 is opened on the top of the partition 51. This design is conducive to the action ring 53 rotating under force to drive the action rod 54 to rotate.

[0034] One end of a force spring 56 is fixedly connected to the inner wall of the slot 55. A baffle 57 is fixedly connected to the end of the force spring 56 away from the inner wall of the slot 55. A connecting rod 58 is fixedly connected to the circumferential surface of the action ring 53. A scraper 59 is fixedly connected to the bottom of the connecting rod 58. This design is conducive to the connecting rod 58 being subjected to force and rotating with the action ring 53.

[0035] The baffle 57 is slidably connected to the inner wall of the slot 55, and the scraper 59 is slidably connected to the top of the partition 51. The scraper 59 is T-shaped, which is beneficial for the scraper 59 to be able to scrape on the top of the partition 51.

[0036] The size of the feed trough 52 is smaller than the size of the baffle 57. The action ring 53 is located on the top of the partition 51. One end of the action rod 54 is set as an arc surface. This design helps the baffle 57 to block the feed trough 52.

[0037] According to the above structure, in the screening device 4, in order to enable the screening plate 46 to stably screen the material, when the rotating shaft 43 rotates, it can drive the actuating ring 53 to rotate, so that the actuating rod 54 is subjected to force and comes into contact with the arc surface of the baffle 57, forcing the baffle 57 to slide on the inner wall of the slot 55. When the actuating rod 54 continues to rotate until it no longer comes into contact with the baffle 57, the baffle 57 can be reset by the elastic force of the force spring 56, so that the baffle 57 is subjected to force and intermittently opens the feed chute 52, so that the material intermittently falls from the feed chute 52. When the actuating ring 53 rotates, it can drive the connecting rod 58 to rotate, forcing the scraper 59 to be subjected to force and scrape on the top of the partition 51, and it will also come into contact with the arc surface of the baffle 57, increasing the speed at which the baffle 57 intermittently opens the slot 55, and can also scrape the material into the inside of the feed chute 52, so that the material enters the inside of the machine body 2 evenly and orderly, ensuring that the screening work of the screening plate 46 can proceed smoothly.

[0038] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the field.
