Description

Technical Field

[0001] This utility model relates to the field of vibratory material feeder technology, and more specifically, to a vibratory material feeder that facilitates material feeding. Background Technology

[0002] Screening is an important step in the granulation process. Its purpose is to remove particles that do not meet the particle size requirements and ensure the quality and appearance of the finished product. Vibrating screens are a common screening equipment used to screen materials. In order to ensure the quality of screening, a material distributor is needed to evenly feed the material onto the vibrating screen.

[0003] A search revealed that utility model patent CN222369610U discloses a vibrating material distributor for a dual-frequency vibrating screen, comprising a material distribution shell, a vibrating motor, a dust cover, a material distribution screen frame, and a center plate. The dust cover is located on top of the material distribution shell. Two vibrating motors are located at one end of the material distribution shell. A material distribution screen frame is inserted into two inclined mounting slots on the two inner sidewalls of the material distribution shell. A material distribution screen is fixed inside the material distribution screen frame. A dispersing arc plate is fixed to the upper end of the center plate. This patent, by incorporating a material distribution shell, a material distribution screen frame, a material distribution screen, a vibrating motor, a center plate, a dispersing arc plate, mounting slots, and a dust cover, solves the problems of imperfect material distribution methods in conventional material distributors, inconvenient disassembly and assembly of the screen-like material distribution structure in the material distributor, and the open structure of the material distributor during use, which easily causes dust to fly, pollute the environment, and increase material costs. However, the above patent still has the following shortcomings: Although the dispersing arc plate can disperse the material onto the two screens, the material will first pass through the upper end of the screen and then move downwards under the action of vibration. This will result in more material falling from the upper end of the screen and less material falling from the lower end of the screen, affecting the uniformity of the fabric. At the same time, when the material moves to the screen after passing through the dispersing arc plate, the upper end of the screen is prone to blockage due to excessive material, affecting the quality of the fabric. Therefore, we have proposed a vibrating fabric distributor that facilitates material feeding. Utility Model Content

[0004] In view of the problems existing in the prior art, the purpose of this utility model is to provide a vibratory material feeder that facilitates material feeding.

[0005] To solve the above problems, this utility model adopts the following technical solution: a vibrating material feeder for easy material feeding, comprising a material shell, a material cover installed on the top of the material shell, two scraping mechanisms provided on the material cover, two inverted V-shaped mounting brackets provided in the inner cavity of the material shell, inverted V-shaped screens installed on the top surfaces of the two inverted V-shaped mounting brackets, a feed pipe fixedly sleeved on the top of the material cover, an inverted V-shaped sliding plate fixedly connected to the inner cavity of the material cover and directly below the feed pipe, and two material distribution devices rotatably connected to the inner cavity of the material cover. The two material distribution boxes are located below the two ends of the inverted V-shaped sliding plate. One end of the rotating shaft of each of the two material distribution boxes extends to the outside of the fabric cover and is fixedly fitted with a gear. A mounting base is fixedly connected to the side of the fabric cover. An electric push rod is fixedly installed on the mounting base. A drive base is fixedly connected to the output end of the electric push rod. A transverse frame is fixedly connected to the bottom end of the drive base. Straight racks are respectively provided at the bottom of both ends of the transverse frame. The two straight racks mesh with two gears respectively. Vibration motors are respectively provided at both ends of the fabric cover.

[0006] As a preferred embodiment of this utility model, the scraping mechanism includes a servo motor fixedly installed on the side of the fabric cover, a slide rod fixedly sleeved in the inner cavity of the fabric cover, and a reciprocating screw rotatably connected to the inner cavity of the fabric cover. A moving block is threaded onto the outer side of the reciprocating screw, and the moving block and the slide rod are movably sleeved together. A plurality of scraping columns are fixedly connected to the bottom surface of the moving block, and the output shaft of the servo motor is connected to the end of the reciprocating screw.

[0007] As a preferred embodiment of this utility model, an installation frame is fixedly sleeved on the outer side of the top of the fabric shell and the outer side of the bottom of the fabric cover. Multiple screw holes are opened on both installation frames, and bolts are installed in the inner cavity of the screw holes.

[0008] As a preferred embodiment of this utility model, the side and end faces of the inverted V-shaped screen are respectively attached to the inner wall of the fabric shell.

[0009] In a preferred embodiment of this utility model, the front and rear ends of the material distribution box are respectively fitted to the inner wall of the fabric cover.

[0010] As a preferred embodiment of this utility model, the two scraping mechanisms are respectively located above the two ends of the inverted V-shaped sliding plate.

[0011] Compared with the prior art, the advantages of this utility model are as follows: In this utility model, the material entering the cloth cover from the feed pipe is divided into two parts by the inverted V-shaped sliding plate, and the two parts of the material enter two distributing boxes respectively. At the same time, the electric push rod drives the drive seat, the transverse frame and the rack and pinion to move laterally back and forth. The meshing transmission between the rack and pinion and the gear drives the distributing box to swing back and forth, thereby changing the position of the material at the bottom of the distributing box falling onto the inverted V-shaped screen, avoiding the material from clogging and accumulating on the inverted V-shaped screen, and ensuring the uniformity of the material falling from the inverted V-shaped screen onto the vibrating screen, thus improving the practicality of this easy-to-discharge vibrating cloth distributor.

[0012] In this invention, when the material slides on the inverted V-shaped slide plate, a servo motor drives the reciprocating screw to rotate. Through the threaded engagement between the reciprocating screw and the moving block, the moving block and the scraper column move rapidly back and forth along the axial direction of the slide bar. The scraper column scrapes the material sliding on the inverted V-shaped slide plate, making the material uniform in the front-back direction of the inverted V-shaped slide plate. This ensures the uniformity of the material entering the inner cavity of the distribution box in the front-back direction, and further ensures the uniformity of the material falling onto the inverted V-shaped screen in the front-back direction. This also ensures the uniformity of the material falling onto the vibrating screen, thus improving the working quality of this easy-to-discharge vibrating distributor. Attached Figure Description

[0018] Please see Figure 1-5 A vibratory material feeder for easy material feeding includes a material housing 1, a material cover 2 mounted on the top of the material housing 1, two scraping mechanisms 3 on the material cover 2, two inverted V-shaped mounting brackets 4 inside the material housing 1, inverted V-shaped screens 5 mounted on the top surfaces of the two inverted V-shaped mounting brackets 4, a feed pipe 15 fixedly sleeved on the top of the material cover 2, an inverted V-shaped sliding plate 6 fixedly connected inside the material cover 2 and directly below the feed pipe 15, and two distributing boxes 7 rotatably connected inside the material cover 2, the two distributing boxes 7 being located on the inverted V-shaped sliding plate. Below both ends of plate 6, one end of the rotating shaft of each of the two material distribution boxes 7 extends to the outside of the fabric cover 2 and is fixedly sleeved with gear 8. The side of the fabric cover 2 is fixedly connected to the mounting base 9, and an electric push rod 10 is fixedly installed on the mounting base 9. The output end of the electric push rod 10 is fixedly connected to the drive base 11, and the bottom end of the drive base 11 is fixedly connected to the transverse frame 12. The bottom of both ends of the transverse frame 12 is respectively provided with a straight rack 13, and the two straight racks 13 mesh with the two gears 8 respectively. Vibration motors 14 are respectively provided at both ends of the fabric shell 1.

[0019] In this embodiment, the material feeder is powered by an external power line and is controlled by a controller on the vibrating screen. The material feeder shell 1 is installed at the higher feed inlet of the linear vibrating screen so that the material falling below the material feeder shell 1 can be screened by the vibrating screen. In addition, the inverted V-shaped screen 5 is installed on the inverted V-shaped mounting bracket 4 with screws so that the inverted V-shaped screen 5 can be replaced.

[0020] For details, please refer to Figure 4 and Figure 5 The scraping mechanism 3 includes a servo motor 18 fixedly installed on the side of the fabric cover 2, a slide rod 17 fixedly sleeved in the inner cavity of the fabric cover 2, and a reciprocating screw 16 rotatably connected in the inner cavity of the fabric cover 2. A moving block 19 is threaded on the outer side of the reciprocating screw 16. The moving block 19 and the slide rod 17 are movably sleeved. A plurality of scraping columns 20 are fixedly connected to the bottom surface of the moving block 19. The output shaft of the servo motor 18 is connected to the end of the reciprocating screw 16.

[0021] In this embodiment, the movable block 19 is provided with a threaded hole that is threadedly connected to the reciprocating screw 16 and a round hole that is movably connected to the slide rod 17. The movable block 19 is limited by the movable connection between the slide rod 17 and the movable block 19, so that the movable block 19 and the scraper column 20 can only reciprocate along the axial direction of the reciprocating screw 16.

[0022] For details, please refer to Figure 2 An installation frame 21 is fixedly fitted to the outer side of the top of the fabric shell 1 and the outer side of the bottom of the fabric cover 2. Multiple screw holes 22 are opened on both installation frames 21, and bolts 23 are installed in the inner cavity of the screw holes 22.

[0023] In this embodiment, the fabric cover 2 and the fabric shell 1 are connected by the cooperation of the mounting frame 21, screw holes 22 and bolts 23.

[0024] For details, please refer to Figure 3 The sides and ends of the inverted V-shaped screen 5 are respectively attached to the inner wall of the fabric shell 1.

[0025] In this embodiment, the inverted V-shaped screen 5 is designed to further separate the material falling from the distribution box 7, so that the material falls evenly onto the screening machine. The aperture of the inverted V-shaped screen 5 is larger than the aperture of the material.

[0026] For details, please refer to Figure 5 The front and rear ends of the material distribution box 7 are respectively attached to the inner wall of the fabric cover 2.

[0027] In this embodiment, the material distribution box 7 is designed to completely catch the material sliding off the inverted V-shaped slide plate 6, so that the material can be evenly distributed by the swinging material distribution box 7.

[0028] For details, please refer to Figure 4 and Figure 5 The two scraping mechanisms 3 are located above the two ends of the inverted V-shaped slide plate 6, respectively.

[0029] In this embodiment, the scraping columns 20 on the two scraping mechanisms 3 are ensured to scrape the material sliding down from both ends of the inverted V-shaped slide plate 6.

[0030] Working principle: In use, the material is first introduced into the inner cavity of the fabric cover 2 through the feed pipe 15. At this time, the material falls onto the inverted V-shaped slide plate 6. The top of the inverted V-shaped slide plate 6 divides the falling material into two parts, and the two parts slide down to the two ends of the inverted V-shaped slide plate 6 respectively. Then, the servo motor 18 is started to drive the reciprocating screw 16 to rotate. Through the threaded engagement between the reciprocating screw 16 and the moving block 19, the moving block 19 and the scraper column 20 move back and forth rapidly along the axis of the slide rod 17. The scraper column 20 scrapes the material sliding on the inverted V-shaped slide plate 6, making the material uniform in the front and back direction of the inverted V-shaped slide plate 6. Then, the material on the inverted V-shaped slide plate 6 falls from its bottom end into the distribution box 7, so that... Material falling into the distribution box 7 falls from the bottom of the distribution box 7 onto the inverted V-shaped screen 5 inside the fabric shell 1. Meanwhile, the electric push rod 10 is activated, driving the drive base 11, the transverse frame 12, and the rack and pinion 13 to move laterally back and forth. Through the meshing transmission between the rack and pinion 13 and the gear 8, the distribution box 7 swings back and forth, thereby changing the position of the material falling from the bottom of the distribution box 7 onto the inverted V-shaped screen 5, preventing material blockage on the screen. Finally, the vibration motor 14 is activated, causing the fabric shell 1 and the inverted V-shaped screen 5 inside the fabric shell 1 to vibrate. Simultaneously, the material's own weight causes it to fall through the screen holes of the inverted V-shaped screen 5 into the vibrating screen, where it is then screened.

[0031] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model based on the technical solution and its improved concept should be covered within the protection scope of the present utility model.
