[0003] When producing robucoid essential oil, the raw materials need to be screened by a screening machine. When the existing raw material screening machine is in use, the motor drives the toggle block to rotate, so that the toggle block drives multiple sets of screens to move up and down to screen the raw materials. However, the up and down vibration amplitude of the screen is fixed, which is difficult to adjust according to different materials, affecting the screening effect. Utility Model Content

[0004] The purpose of the utility model is to provide a multi-stage screening type raw material screening machine to solve the problem of the existing raw material screening machine being difficult to adjust the vibration amplitude proposed in the above background technology.

[0005] To achieve the above object, the utility model provides the following technical solution: a multi-stage screening type raw material screening machine, comprising: a machine body and a threaded rod, the top of the machine body is connected to a feed port, and a sieve plate is provided inside the machine body.

[0013] Compared with the existing technology, the beneficial effects of this multi-stage screening type raw material screening machine are:

[0014] 1. When producing the essence oil of robucoid, it is necessary to screen the raw materials through a screening machine. The drive shaft is driven to rotate by starting the motor. When the drive shaft rotates, it can drive the two sets of fixed plates to rotate synchronously. The movable plates on both sides of the fixed plate will contact the two sets of sieve plates through rollers respectively to move the sieve plates. The limit rods around the sieve plates will slide inside the connecting block and squeeze the spring. When the movable plate is free from the squeezing of the sieve plate, the spring will reset, thereby pushing the movable plate to move. In this way, the sieve plate can vibrate in the machine body to screen the material entering at the feed inlet. The two sets of sieve plates can screen the material multiple times to separate materials of different volumes. In this way, the above operation can facilitate the graded screening of the material in the raw material screening machine and adjust the vibration amplitude during screening.

[0015] 2. When producing the essence oil of robucoid, the raw materials need to be screened through a screening machine. The worm is engaged with the worm wheel by rotating the worm, so that the worm wheel drives the rotating plate to rotate. When the rotating plate rotates, the connecting belt can be pulled to move together. The connecting belt can separate the bottom space of the receiving box. By changing the deflection angle of the rotating plate in the receiving box, the space on the left and right sides of the receiving box can be changed, thereby adapting to the amount of material screened by the upper and lower sieve plates. In this way, the above operation can facilitate the collection of materials that have not passed through the sieve plate in the screening machine. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0024] See also Figure 1-Figure 5 The utility model provides a technical solution: a multi-stage screening type raw material screening machine, comprising: a body 1 and a threaded rod 8, the top of the body 1 is connected to a feed port 2, and a sieve plate 3 is provided inside the body 1.

[0025] The interior of the body 1 is movably connected to a transmission shaft 4 through a bearing, and a fixed plate 10 is fixedly connected to the outside of the transmission shaft 4. A motor 16 is fixed to one end of the transmission shaft 4, and the bottom of the motor 16 is fixedly connected to the body 1 through a mounting plate.

One end of the threaded rod 8 is movably connected to the fixed plate 10 through a bearing; the outer side of the threaded rod 8 is threadedly connected to a movable plate 9, and the inner side of the movable plate 9 is slidably connected to a limit rod 11. , one end of the limit rod 11 is fixedly connected to the fixed plate 10; a connecting block 12 is fixed around the sieve plate 3, and a sliding rod 14 is slidably connected inside the connecting block 12, and the top of the sliding rod 14 is fixedly connected to the body 1; a spring 13 is fixed to the bottom of the sliding rod 14, and the bottom of the spring 13 is fixedly connected to the sieve plate 3, and guide plates 15 are fixed on both sides of the body 1. A sliding groove matching the limit rod 11 is provided inside the fixed plate 10, and a through groove matching the sliding rod 14 is provided inside the connecting block 12. The bevel gear a6 and the bevel gear b7 constitute an engaging transmission structure, and the threaded rod 8 and the movable plate 9 constitute a threaded transmission structure.

[0026] During specific implementation, when producing the essence oil of Robutline, it is necessary to screen its raw materials through a screening machine, and the transmission shaft 4 is driven to rotate by starting the motor 16. When the transmission shaft 4 rotates, it can drive the two sets of fixed plates 10 to rotate synchronously, and the movable plates 9 on both sides of the fixed plate 10 will contact the two sets of sieve plates 3 through rollers respectively, so that the sieve plates 3 move, and the limiting rods 11 around the sieve plates 3 will slide inside the connecting block 12 and squeeze the spring 13. When the movable plate 9 is free from squeezing the sieve plate 3, the spring 13 will reset, thereby pushing the movable plate 9 to move, so that the sieve plate 3 can vibrate in the machine body 1 to screen the material entering at the feed inlet 2. The two sets of sieve plates 3 can screen the material multiple times to separate materials of different volumes;

[0027] When it is necessary to adjust the vibration amplitude of the sieve plate 3 in the screening machine, the bevel gear a6 is driven to rotate by rotating the connecting shaft 5, so that the bevel gear a6 is engaged with the two sets of bevel gears b7. At this time, the two sets of bevel gears b7 will drive the two sets of threaded rods 8 and the movable plate 9 to perform threaded transmission, so that the movable plate 9 is moved, and the limit rod 11 will limit it. By adjusting the position of the movable plates 9 on both sides of the fixed plate 10, the distance that the movable plate 9 pushes the sieve plate 3 to move can be changed, thereby adjusting the vibration amplitude of the sieve plate 3. In this way, the above operation can facilitate the graded screening of materials in the raw material screening machine and adjust the vibration amplitude during screening.

[0028] See also Figure 1 、 Figure 2 and Figure 6 , material receiving boxes 17 are provided on both sides of the machine body 1, and a partition plate 18 is fixed inside the material receiving box 17.

[0029] During specific implementation, when producing the essence oil of robucoid, it is necessary to screen its raw materials through a screening machine. When collecting the raw materials that have not passed through the sieve plate 3, guide plates 15 are set on both sides of the sieve plate 3. The guide plates 15 can guide the materials into the receiving box 17 for collection. When the amount of materials screened in the upper and lower sieve plates 3 is very different, the worm 19 can be rotated to engage with the worm gear 20, so that the worm gear 20 drives the rotating plate 21 to rotate. When the rotating plate 21 rotates, the connecting belt 22 can be pulled to move together. The connecting belt 22 can separate the bottom space of the receiving box 17. By changing the deflection angle of the rotating plate 21 in the receiving box 17, the space on the left and right sides of the receiving box 17 can be changed, thereby adapting to the amount of materials screened in the upper and lower sieve plates 3. In this way, the above operation can facilitate the collection of materials that have not passed through the sieve plate 3 in the screening machine.
