Description

Technical Field

[0001] This utility model relates to the field of nut food production technology, specifically to a screening machine that can screen star anise particles. Background Technology

[0002] In the field of nut food production technology, especially in the production and processing of granular ingredients such as star anise, screening is a crucial step. Existing star anise particle screening machines mostly use mechanical vibration screening, which separates star anise particles of different sizes through a vibrating screen. These screening machines typically include a vibration source, a screen, and a collection device. The vibration source generates vibration, causing the star anise particles on the screen to vibrate and jump. Small particles fall through the screen holes, while large particles remain on the screen, thus achieving the purpose of screening.

[0003] Although existing star anise particle screening machines meet production needs to a certain extent, they have significant shortcomings in adjusting the size of the screened particles. Specifically, the screen aperture of existing screening machines is often fixed, which means that once the screen is selected, the size of the star anise particles screened is also determined. However, in actual production, the size of star anise particles may vary due to different processes such as harvesting and drying. Screens with fixed apertures cannot meet the need for flexible adjustment of the size of the screened particles. Utility Model Content

[0004] The present invention addresses the problem that in existing technologies, the mesh size of the screen is fixed, and once the screen is selected, the size of the star anise particles screened out is also determined. However, in actual production processes, the size of the star anise particles may vary due to different processes such as harvesting and drying. Screens with fixed mesh sizes cannot meet the need for flexible adjustment of the size of the screened particles. Therefore, a screening machine that can screen star anise particles is proposed.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A screening machine for screening star anise particles includes a frame, and a plurality of vibration damping mechanisms are provided on the top of the frame for vibration reduction.

[0007] The vibration damping mechanism includes an inner sleeve rod, which is fixedly connected to the top of the frame. An outer sleeve tube is fitted onto the outer circumferential wall of the inner sleeve rod. Both the inner circumferential wall of the outer sleeve tube and the outer circumferential wall of the inner sleeve rod are roughened. A spring is fixedly connected between the bottom inner wall of the inner sleeve rod and the top inner wall of the outer sleeve tube. The spring is fitted onto the outside of the outer sleeve tube and the inner sleeve rod. A screening mechanism for screening is fixedly installed on the top of multiple outer sleeve tubes.

[0008] Furthermore, the screening mechanism includes a screening box, which is fixedly connected to the top of multiple outer tubes. Multiple through grooves are provided on both inner walls of the screening box, and an adjustment mechanism for adjusting the size of the screened particles is provided inside the screening box.

[0009] Furthermore, the adjustment mechanism includes multiple first screening plates and two second screening plates. Multiple limiting sliders are fixedly connected to both sides of the first screening plates. The limiting sliders are slidably connected in corresponding grooves. Two extension shafts are fixedly connected to the bottom of the first screening plates. The second screening plates are slidably connected between the inner walls of both sides of the screening box. The second screening plates slide through one inner wall of the screening box. Multiple through limiting grooves are opened on the top of the second screening plates. The multiple limiting grooves are relatively concentrated at one end and relatively dispersed at the other end on the second screening plates. The extension shafts pass through the corresponding limiting grooves.

[0010] Furthermore, L-shaped connecting blocks are fixedly connected to both sides of the screening box, and the same connecting plate is fixedly connected between the two L-shaped connecting blocks. Threaded rods are rotatably connected between both sides of the connecting plate and the inner walls of both sides of the screening box. Rotary motors are provided on both sides of the screening box. The output shaft of the rotary motor rotates through one inner wall of the screening box and is fixedly connected to one end of the corresponding threaded rod. A drive plate is fixedly connected to the bottom of the second screening plate, and one end of the threaded rod is threaded through the corresponding drive plate.

[0011] Furthermore, a through discharge port is provided on one side of the screening box, and a side door is hinged to the side of the screening box with the discharge port. One side of the side door is fixedly connected to one side of the screening box by a latch.

[0012] Furthermore, the top of the screening box is equipped with multiple vibration motors, and the top of the screening box has a through-feed inlet, with a barrier fixedly connected to the top of the feed inlet.

[0013] Beneficial effects:

[0014] The screening machine described in this technology, which can screen star anise particles, achieves an effective vibration reduction and buffering effect through multiple vibration damping mechanisms, including an inner sleeve rod, an outer sleeve tube, and a spring assembly. During the operation of the screening machine, the strong vibration generated by the vibrating motor can be effectively absorbed and dispersed through the vibration damping mechanism, avoiding the direct impact of vibration on the frame and the surrounding environment, reducing the transmission of noise and vibration, thereby protecting the stability and service life of the equipment, and also providing a more comfortable working environment for the operators.

[0015] The present invention describes a screening machine for screening star anise particles. Through a designed adjustment mechanism, including multiple sliding first and second screening plates, as well as corresponding chutes, extension shafts, and limiting grooves, the size of the screened particles can be flexibly adjusted. In actual production, according to the different size requirements of the star anise particles, simply start the rotating motor, and the rotation of the threaded rod drives the second screening plate to move, thereby driving the first screening plate to adjust synchronously. This allows for quick and accurate adjustment of the screening gap, meeting the screening needs of various sizes of star anise particles and improving the applicability and flexibility of the equipment.

[0016] The screening machine described in this technology, capable of screening star anise particles, achieves high-efficiency screening and excellent particle dispersing ability through its vibrating motor and multi-layer screening plate structure. The operation of the vibrating motor causes the screening box and its internal screening plates to vibrate strongly, effectively dispersing the poured star anise particles and promoting their passage through the gaps between the screening plates, thereby improving screening efficiency and quality. At the same time, the multi-layer screening plate design allows the star anise particles to undergo multiple screenings, further ensuring that the screened particles are of uniform size and meet production requirements, thus improving overall production efficiency and product quality.

[0017] This technology utilizes multiple vibration damping mechanisms, including inner sleeves, outer sleeves, and spring assemblies, to achieve effective vibration reduction and buffering. During the operation of the screening machine, the strong vibrations generated by the vibrating motor are effectively absorbed and dispersed through these damping mechanisms, preventing direct impact on the frame and surrounding environment. This reduces noise and vibration transmission, thus protecting the stability and lifespan of the equipment and providing a more comfortable working environment for operators. The designed adjustment mechanism, including multiple sliding first and second screening plates, along with corresponding chutes, extension shafts, and limiting grooves, allows for flexible adjustment of the particle size. In actual production, to meet the different size requirements of the octagonal particles, simply start the rotating motor. The rotation of the threaded rod drives the second screening plate to move, which in turn drives the first screening plate to adjust synchronously. This allows for quick and accurate adjustment of the screening gap, meeting the screening needs of various sizes of star anise particles and improving the applicability and flexibility of the equipment. Furthermore, the vibration motor and multi-layer screening plate structure achieve highly efficient screening and excellent particle dispersing ability. The vibration motor causes strong vibrations in the screening box and its internal screening plates, effectively dispersing the poured-in star anise particles and promoting their passage through the screening plate gaps, thus improving screening efficiency and quality. Simultaneously, the multi-layer screening plate design ensures that the star anise particles undergo multiple screenings, further guaranteeing uniform particle size that meets production requirements, thereby improving overall production efficiency and product quality.

[0023] The technical solution of this utility model will now be clearly and completely described with reference to the accompanying drawings.

[0024] Example 1: Refer to Figure 1-4 A screening machine includes a frame 1, with multiple vibration damping mechanisms 3 mounted on the top of the frame 1. Each vibration damping mechanism 3 includes an inner sleeve rod 21 securely connected to the top of the frame 1. An outer sleeve tube 20 is fitted over the inner sleeve rod 21, with both the inner wall of the outer sleeve tube 20 and the outer wall of the inner sleeve rod 21 being roughened to enhance friction. A spring 22 is fixedly connected between the bottom inner wall of the inner sleeve rod 21 and the top inner wall of the outer sleeve tube 20, surrounding both the outer sleeve tube 20 and the inner sleeve rod 21 to provide vibration damping for the entire mechanism. The tops of the multiple outer sleeve tubes 20 collectively support a screening mechanism 2 for screening.

[0025] The screening mechanism 2 mainly consists of a screening box 8, which is fixedly installed on the top of the outer sleeve 20. Multiple through-grooves 9 are formed on both inner walls of the screening box 8 to facilitate the installation and adjustment of the internal screening plates. An adjustment mechanism is also configured inside the screening box 8 to flexibly adjust the size of the screened particles. This adjustment mechanism includes multiple first screening plates 10 and two second screening plates 13. The first screening plates 10 are slidably connected to the grooves 9 via limiting sliders 11 on both sides, and two extension shafts 12 are fixedly connected to their bottoms. The second screening plates 13 are also slidably connected between the inner walls of the screening box 8 on both sides and can slide out from one inner wall of the screening box 8. Multiple limiting grooves 14 are formed on their tops, allowing the extension shafts 12 to pass through them, thereby connecting the first screening plates 10 and the second screening plates 13 and achieving coordinated adjustment between them.

[0026] The adjustment mechanism in screening mechanism 2, in addition to including multiple first screening plates 10 and two second screening plates 13, also includes components such as L-shaped connecting blocks 15, connecting plates 16, threaded rods 17, rotating motors 18, and drive plates 19. The L-shaped connecting blocks 15 are firmly connected to both sides of the screening box 8, and the two L-shaped connecting blocks 15 are connected by connecting plates 16. A threaded rod 17 is rotatably connected between each side of the connecting plate 16 and the inner walls of both sides of the screening box 8. A rotating motor 18 is also installed on each side of the screening box 8, with its output shaft passing through one inner wall of the screening box 8 and firmly connected to one end of the corresponding threaded rod 17. A drive plate 19 is fixedly connected to the bottom of the second screening plate 13, and one end of the threaded rod 17 passes through the corresponding drive plate 19 via a threaded connection.

[0027] This technology can be used in the production of nut products, as well as in other fields.

[0028] Example 2: Reference Figure 1-4 An improvement upon Embodiment 1: A screening machine capable of screening star anise particles, applied in the nut food production field. The screening box 8 has a through-feed inlet at its top, with a retaining wall 4 fixedly connected to the top of the inlet. A through-feed outlet 6 is also provided on one side of the screening box 8, with a hinged side door 7 for easy discharge of the screened particles. One side of the side door 7 is securely connected to the side of the screening box 8 via a latch, ensuring a tight seal during the screening process.

[0029] Working principle: In this application, when people need to use this screening machine, they only need to pour the nuts to be screened into the enclosure 4, and then start the vibration motor 5. The vibration motor 5 will then drive the screening box 8 to vibrate up and down, which in turn will cause the multiple first screening plates 10 inside the screening box 8 to vibrate together, so as to break up the poured nuts. Then, the small particles will fall through the gap between the two first screening plates 10 into the second screening plates 13 inside the screening box 8 for initial screening. Since the gap between the two second screening plates 13 is smaller than the gap between the two first screening plates 10, the nuts are further screened. After being screened by the first screening plate 10, the particles will be screened again through the gap between the two second screening plates 13, and then discharged. When it is necessary to set the size of the screened particles, simply start the rotating motor 18. The output shaft of the rotating motor drives the threaded rod to rotate, which in turn drives the drive plate to move through the threaded connection. Then the drive plate drives the second screening plate 13 to move outward to adjust the size of the particles screened in the second screening. At the same time, the multiple limiting grooves 14 opened on the top of the second screening plate 13 will drive the multiple first screening plates 10 to move away from each other through the extension shaft 12 to adjust the size of the particles screened in the first screening.

[0030] As is well known to those skilled in the art, the working principles and wiring methods of the vibration motor 5 and the rotary motor 18 are commonplace and belong to conventional methods or common knowledge. They will not be elaborated here. Those skilled in the art can make any selections according to their needs or convenience.
