Description

Technical Field

[0001] This utility model relates to the field of fruit raw material screening technology, and in particular to an adjustable fruit raw material screening machine. Background Technology

[0002] In the field of fruit raw material screening, traditional screening equipment mostly adopts a fixed screen structure, which has significant limitations. Its screen aperture is fixed and can only adapt to the screening of a single size of fruit. When facing different types and sizes of fruit raw materials, the screen needs to be changed frequently, which is cumbersome, time-consuming and labor-intensive, and seriously affects production efficiency. At the same time, most traditional equipment is single-stage screening, which makes it difficult to achieve multi-stage accurate grading of fruit raw materials. The grading efficiency is low and the accuracy is insufficient, which cannot meet the needs of the modern fruit processing industry for efficient and accurate screening, and has certain adverse effects on the user process. In order to overcome the shortcomings of existing technologies, we propose an adjustable fruit raw material screening machine. Utility Model Content

[0003] The main objective of this invention is to provide an adjustable fruit raw material screening machine, which can effectively solve the problems in the background technology.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0005] An adjustable fruit raw material screening machine includes a support platform. A screening platform is provided on one side of the support platform. A second side baffle and a partition plate are fixedly connected to the upper end of the screening platform, and multiple rectangular through slots are opened on the surface of the screening platform. A first fixed frame and two second fixed frames are fixedly connected to the lower end of the screening platform. A support plate is fixedly connected to the lower end of the first fixed frame, and a second servo motor is detachably connected to one end of the support plate. A first threaded rod is detachably connected to the output shaft of the second servo motor. A first gear is fixedly connected to the outer surface of the first threaded rod, and a second gear meshes with one side of the first gear. A second threaded rod is fixedly connected inside the second gear. A first moving block is threadedly connected to the outer surface of the first threaded rod, and a first screening plate is fixedly connected to the upper end of the first moving block. A second moving block is threadedly connected to the outer surface of the second threaded rod, and a second screening plate is fixedly connected to the upper end of the second moving block. Guide rods are fixedly connected to the two second fixed frames, and third moving blocks are slidably connected to the outer surfaces of the guide rods. Multiple feeding hoppers are fixedly connected to the lower end of the screening platform.

[0006] Preferably, two first side baffles are fixedly connected to the upper end of the support platform, a conveyor belt is arranged between the two first side baffles, and a push plate is fixedly connected to the outer surface of the conveyor belt. A U-shaped baffle is fixedly connected to the upper end of the two first side baffles, and a first servo motor for driving the conveyor belt is detachably connected to the front end of one of the first side baffles.

[0007] Preferably, the screening table is an inclined surface, and one side of the screening table is a slope with an inclination angle greater than that of the screening table surface. Several partition plates are provided and uniformly fixedly connected to the upper end of the screening table.

[0008] Preferably, a plurality of rectangular through slots are provided and evenly distributed on the surface of the screening table, and a partition plate is fixedly connected to the upper part of the screening table between every two rectangular through slots to separate the two rectangular through slots.

[0009] Preferably, the second servo motor is detachably connected to one end of the support plate by bolts, and the output shaft of the second servo motor is detachably connected to the first threaded rod by a coupling. The first moving block is provided with a plurality of evenly threaded connections to the outer surface of the first threaded rod.

[0010] Preferably, the second gear is fixedly connected to the outer surface of the second threaded rod, and the second moving block is provided with a plurality of evenly threaded connections to the outer surface of the second threaded rod. The widths of the first screening plate and the second screening plate gradually decrease from left to right.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] This adjustable fruit raw material screening machine, through the synchronous rotation of the first and second threaded rods driven by a second servo motor and two meshing gears, can precisely and synchronously adjust the spacing between all the first and second screening plates. Users only need to start the second servo motor to steplessly adjust the size of the screening gap according to the target size range of the fruit raw materials to be screened. This significantly overcomes the problems of low efficiency and poor flexibility of traditional fixed screens or screen replacement methods, enabling one machine to adapt to the high-efficiency screening needs of various types and specifications of fruit raw materials.

[0013] This adjustable fruit raw material screening machine combines an inclined screening table, equidistantly arranged partitions, rectangular channels, a first and second screening plate with gradually decreasing width, and a feeding hopper. Under the action of gravity, the fruit raw materials slide down the inclined surface of the screening table. As the gap between the first and second screening plates gradually increases, fruits smaller than the current gap size will fall into the feeding hopper below through the corresponding rectangular channels in sequence. This achieves continuous multi-level automatic grading and screening of fruit raw materials on a single sliding path. The structure is compact, the efficiency is high, and it eliminates the need for complex conveying or sorting mechanisms.

[0014] The adjustable fruit raw material screening machine has a guide rod set in the second fixed frame and a third moving block slidably connected thereto, which is fixedly connected to the first screening plate and the second screening plate. This provides precise linear guidance and stable support for the movement of the screening plates when adjusting the spacing and withstanding the impact of the fruit, effectively preventing the screening plates from tilting, jamming or vibrating during movement or operation, and ensuring the reliability of the screening action and the grading accuracy.

Detailed Implementation

[0021] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0022] Example 1, as Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5As shown, an adjustable fruit raw material screening machine includes a support platform 1 and a screening platform 7 fixed to one side of the support platform 1. Two first side baffles 2 are welded to the upper end of the support platform 1, and an annular conveyor belt 3 is installed between the two. Multiple push plates 4 are fixed at equal intervals on the surface of the conveyor belt 3 for pushing the fruit raw materials. A U-shaped baffle 5 is fixedly connected to the upper end of the first side baffle 2 to prevent the raw materials from spilling. A first servo motor 6 is installed at the front end of one of the first side baffles 2, and its output shaft is connected to the drive roller of the conveyor belt 3 through a coupling to realize the directional conveying of the raw materials.

[0023] The screening table 7 is an inclined plane, with a higher ramp at its upper end that connects to the discharge end of the conveyor belt 3 to ensure that the raw material slides into the screening area. A second side baffle 8 and multiple partition plates 9 are welded to the upper end of the screening table 7. Rectangular through slots 10 are opened between adjacent partition plates 9. A first fixed frame 11 and two second fixed frames 12 are fixedly connected to the lower part of the screening table 7. A support plate 13 is welded to the lower end of the first fixed frame 11, and a second servo motor 14 is bolted to its front end. The output shaft of the second servo motor 14 is connected to a first threaded rod 15 via a coupling. A first gear 16 is fixedly connected to the outer surface of the first threaded rod 15 and meshes with a second gear 17. A second threaded rod 18 is fixed inside the wheel 17. Multiple first moving blocks 19 are threadedly connected to the surface of the first threaded rod 15. A first screening plate 20 is welded to the upper end of each moving block. Multiple second moving blocks 21 are threadedly connected to the surface of the second threaded rod 18. A second screening plate 22 is welded to the upper end of each moving block. When the second servo motor 14 is started, the first threaded rod 15 drives the first gear 16 to rotate, and at the same time drives the second gear 17 to rotate in the opposite direction, so that the first threaded rod 15 and the second threaded rod 18 rotate synchronously in the opposite direction. At this time, the distance between the first screening plate 20 and the second screening plate 22 will gradually increase, so that the screening equipment can be adjusted according to different types of fruits.

[0024] Guide rods 23 are fixedly connected to both second fixed frames 12. Multiple third moving blocks 24 are slidably sleeved on the surfaces of the two guide rods 23. Two third moving blocks 24 are fixedly connected to the lower ends of each first screening plate 20 and second screening plate 22 to ensure movement stability. Multiple feeding hoppers 25 are fixedly connected to the lower end of the screening table 7, which correspond to the fruit discharge ports of different sizes.

[0025] It should be noted that this utility model is an adjustable fruit raw material screening machine. In use, the second servo motor 14 is started according to the size requirements of the fruit. It drives the first threaded rod 15 to rotate through the coupling. The first gear 16 rotates and meshes with the second gear 17, so that the second threaded rod 18 rotates synchronously. The synchronous rotation of the first threaded rod 15 and the second threaded rod 18 can drive the first moving block 19 and the second moving block 21 to move axially, thereby driving the first screening plate 20 and the second screening plate 22 to move closer or further apart. The distance between the two is adjusted. The guide rod 23 cooperates with the third moving block 24 to ensure that the screening plate moves smoothly.

[0026] Next, the first servo motor 6 is started to drive the conveyor belt 3 to rotate. Then, the fruit is poured onto the surface of the conveyor belt 3. The surface pusher plate 4 pushes the fruit raw material along the support platform 1. The U-shaped baffle 5 cooperates with the first side baffle 2 to prevent the raw material from spilling. The discharge end of the conveyor belt is connected to the high-end slope of the screening table 7. The raw material slides into the inclined surface of the screening table under the action of gravity and enters the screening area defined by the second side baffle 8 and the partition plate 9.

[0027] Then, the fruit raw materials slide down the inclined surface of the screening table 7. As the width of the first screening plate 20 and the second screening plate 22 gradually decreases from left to right, the distance between the first screening plate 20 and the second screening plate 22 gradually increases from left to right. Therefore, when the fruit slides down the inclined surface to the point where the gap between the first screening plate 20 and the second screening plate 22 is larger than the size of the fruit, the fruit will fall through the rectangular channel 10 into the corresponding feeding hopper 25 for feeding, realizing multi-level size grading. Each feeding hopper 25 corresponds to the discharge port of different sizes of fruit. The screened raw materials are discharged through the feeding hopper, completing the automated grading and screening, which is convenient for subsequent processing or storage.

[0028] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims. The scope of protection of this utility model is defined by the appended claims and their equivalents.
