Description

Technical Field

[0001] This utility model relates to the field of food processing technology, and in particular to a screening device for raisin processing. Background Technology

[0002] Food processing refers to the process of transforming raw materials into food that can be directly consumed by humans or further processed through a series of physical, chemical or biological treatments. Among them, the screening device for raisin processing is a device specifically used in the raisin processing process to screen, grade and remove impurities from raisins.

[0003] A Chinese patent discloses a linear vibration screening machine for raisins (authorization announcement number CN206882126U). The negative pressure fan in the internal air duct of this patented technology can remove the raisins. The implementation of this device improves the cleanliness of food and the cleanliness of the factory environment on the one hand, and avoids secondary pollution of the raisins that are placed later on the other hand.

[0004] Regarding the above-mentioned and existing related technologies, the inventors believe that the following defects often exist: Because the screening devices currently used in raisin processing on the market have internal screening plates designed as non-removable structures, it means that the screening plates cannot be replaced and adjusted according to the specific needs of the screening operation or for different types of raisins. This design limitation significantly restricts the adaptability and flexibility of the raisin screening device, thereby reducing its working efficiency and scope of application to a certain extent. Utility Model Content

[0005] The technical problem to be solved by this utility model is that the screening plates of existing raisin screening devices on the market are usually fixed and cannot be replaced, which limits their adaptability and flexibility, and reduces their work efficiency and scope of application. Therefore, we propose a screening device for raisin processing.

[0006] To achieve the above objectives, this application adopts the following technical solution: a raisin processing screener, comprising a raisin screening device body, a feed inlet fixedly connected to the top of the raisin screening device body, a screening plate installed inside the raisin screening device body, two first circular grooves formed on both sides of the screening plate, and a first spring fixedly connected inside the first circular groove.

[0007] A connecting block is fixedly connected to one side of the main body of the raisin screening device. Two irregularly shaped slots are opened on both sides of the main body. The surface of the connecting block is slidably connected to the inside of the irregularly shaped slot. A round rod is slidably connected to the inside of the irregularly shaped slot. A push block is fixedly connected to one side of the round rod. The surface of the push block is slidably connected to the inside of the irregularly shaped slot. A first round plate is fixedly connected to the other side of the round rod.

[0008] Preferably, the raisin screening device has locking grooves on both sides of its main body, and locking blocks are fixedly connected to both sides of the screening plate. The surfaces of the locking blocks are slidably connected to the interior of the locking grooves.

[0009] Preferably, a second spring is slidably connected to the surface of the round rod, one side of the second spring is fixedly connected to the first round plate, and the other side of the second spring is fixedly connected to the surface of the main body of the raisin sorting device.

[0010] Preferably, the top and bottom of the round rod are provided with sliding grooves, and the top and bottom of the irregular through groove are fixedly connected with sliding blocks, the surface of the sliding blocks being slidably connected to the inside of the sliding groove.

[0011] Preferably, a limiting plate is fixedly connected to one side of the connecting block, and the surface of the limiting plate is slidably connected to the inside of the first circular groove.

[0012] Preferably, the top of the raisin sorting device body has movable grooves on both sides, movable blocks are slidably connected inside the movable grooves, telescopic rods are slidably connected inside the movable blocks, a third spring is slidably connected to the surface of the telescopic rods, and a cleaning brush is fixedly connected to the top of the telescopic rods. The top of the raisin sorting device body has second circular grooves on both sides, and a limiting rod is slidably connected inside the second circular grooves. The top of the cleaning brush has limiting grooves on both sides, and one end of the limiting rod is slidably connected to the inside of the limiting groove.

[0013] Preferably, a fourth spring is slidably connected to the surface of the limiting rod, a second circular plate is fixedly connected to the bottom end of the limiting rod, the bottom end of the fourth spring is fixedly connected to the second circular plate, and the top end of the fourth spring is fixedly connected to the top end inside the second circular groove.

[0014] The technical effects and advantages of this utility model are as follows:

[0015] In this invention, pressing the first circular plate causes the circular plate to move the circular rod and push block into the irregular groove. This push block then pushes the connecting block out of the irregular groove, releasing the limiting position between the raisin screening device body and the screening plate. The screening plate can then be quickly removed from the raisin screening device body. During installation, pressing the connecting block retracts it into the first circular groove, resetting the screening plate. The elasticity of the first spring automatically pushes the connecting block into the irregular groove, reconnecting the screening plate to the raisin screening device body. This design allows for quick removal and replacement of the screening plate from the raisin screening device body. Different sieve plates with different apertures can be used for different screening needs and different types of raisins, improving the flexibility of screening.

[0016] In this invention, by raising the limiting rod, one end of the limiting rod is disengaged from the limiting groove, thus releasing the limiting position of the unblocking brush. Then, the unblocking brush is pressed down so that its bottom end contacts the top end of the screening plate. The unblocking brush is moved to clean the surface of the screening plate. After use, the unblocking brush is reset, and the limiting rod is pulled back to its original position, allowing the unblocking brush to be limited again. This design allows for timely unblocking of the screening holes on the surface of the screening plate when they are blocked by material, preventing material accumulation and ensuring the smooth progress of the screening process, improving screening efficiency, and guaranteeing screening quality.

[0025] The present invention will now be described in further detail with reference to the accompanying drawings and preferred embodiments. These drawings are simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, and therefore only show the components related to the present invention.

[0026] Reference Figure 1 , Figure 2 and Figure 3As shown, this utility model provides a technical solution: a screening device for raisin processing, including a raisin screening device body 1, a feed inlet 2 fixedly connected to the top of the raisin screening device body 1, a screening plate 3 installed inside the raisin screening device body 1, two first circular grooves 4 opened on both sides of the screening plate 3, a first spring 5 fixedly connected inside the first circular groove 4, a connecting block 6 fixedly connected to one side of the first spring 5, two irregular through grooves 7 opened on both sides of the raisin screening device body 1, the surface of the connecting block 6 slidingly connected to the inside of the irregular through groove 7, a round rod 8 slidingly connected inside the irregular through groove 7, a push block 9 fixedly connected to one side of the round rod 8, the surface of the push block 9 slidingly connected to the inside of the irregular through groove 7, and a first circular plate 10 fixedly connected to the other side of the round rod 8. By pressing the first circular plate 10, the raisin screening device body 1 is able to... The first circular plate 10 drives the circular rod 8 and the push block 9 to move into the irregular groove 7, causing the push block 9 to push the connecting block 6 out of the irregular groove 7. This releases the limit between the raisin screening device body 1 and the screening plate 3, allowing the screening plate 3 to be quickly removed from the raisin screening device body 1. During installation, pressing the connecting block 6 retracts it into the first circular groove 4, resetting the screening plate 3. The elasticity of the first spring 5 automatically pushes the connecting block 6 into the irregular groove 7, reconnecting the screening plate 3 to the raisin screening device body 1. This design allows the screening plate 3 to be quickly removed from the raisin screening device body 1 for replacement. Different sieve plates 3 with different apertures can be used for different screening needs and different types of raisins, improving the flexibility of screening.

[0027] Reference Figure 1 and Figure 2 As shown in this embodiment: both sides of the interior of the main body 1 of the raisin sorting device are open.

[0028] A snap-fit ​​groove 11 is provided, and snap-fit ​​blocks 12 are fixedly connected to both sides of the screening plate 3. The surface of the snap-fit ​​block 12 is slidably connected to the inside of the snap-fit ​​groove 11. By setting the snap-fit ​​groove 11 and the first circular plate 10, when the screening plate 3 is installed into the body 1 of the raisin screening device, the snap-fit ​​groove 11 and the first circular plate 10 form a snap-fit. This setting can play a positioning role when the screening plate 3 is installed, and at the same time make the connection between the screening plate 3 and the body 1 of the raisin screening device more stable, avoiding sliding displacement.

[0029] Reference Figure 2As shown in this embodiment: a second spring 13 is slidably connected to the surface of the round rod 8. One side of the second spring 13 is fixedly connected to the first round plate 10, and the other side of the second spring 13 is fixedly connected to the surface of the main body 1 of the raisin screening device. By setting the second spring 13, the displacement of the round rod 8 and the push block 9 can be limited. The elasticity of the second spring 13 abuts against the first round plate 10, and when the equipment vibrates during operation, the round rod 8 is prevented from driving the push block 9 to move.

[0030] Reference Figure 3 As shown in this embodiment: the top and bottom of the round rod 8 are provided with sliding grooves 14, and the top and bottom of one side of the irregular through groove 7 are fixedly connected with sliding blocks 15. The surface of the sliding block 15 is slidably connected to the inside of the sliding groove 14. By making the sliding block 15 slide inside the sliding groove 14, the movement of the round rod 8 can be given linear guidance, making the movement of the round rod 8 more stable and ensuring that the round rod 8 moves along the predetermined route without tilting or shaking.

[0031] Reference Figure 2 As shown in this embodiment: a limiting plate 16 is fixedly connected to one side of the connecting block 6. The surface of the limiting plate 16 is slidably connected to the inside of the first circular groove 4. By setting the limiting plate 16, it can be ensured that one side of the connecting block 6 is kept inside the first circular groove 4 and will not come out of the inside of the first circular groove 4 due to the elasticity of the first spring 5, thus ensuring the stability of the connection between the main body 1 of the raisin screening device and the screening plate 3.

[0032] Reference Figure 4 and Figure 5 As shown in this embodiment: Movable grooves 17 are provided on both sides of the top of the raisin screening device body 1. Movable blocks 18 are slidably connected inside the movable grooves 17. Telescopic rods 19 are slidably connected inside the movable blocks 18. A third spring 20 is slidably connected to the surface of the telescopic rod 19. A cleaning brush 21 is fixedly connected to the top of the telescopic rod 19. Second circular grooves 22 are provided on both sides of the top of the raisin screening device body 1.

[0033] The inner sliding connection of the two circular grooves 22 is a limiting rod 23. The top of the unblocking brush 21 has limiting grooves 24 on both sides. One end of the limiting rod 23 is slidably connected to the inside of the limiting groove 24. By lifting the limiting rod 23, one end of the limiting rod 23 is disengaged from the inside of the limiting groove 24. At this time, the limiting of the unblocking brush 21 is released. Then, the unblocking brush 21 is pressed down so that the bottom end of the unblocking brush 21 contacts the top of the screening plate 3. The unblocking brush 21 is moved to clean the surface of the screening plate 3. After use, the unblocking brush 21 is reset, and the limiting rod 23 is pulled again so that one end of the limiting rod 23 returns to the inside of the limiting groove 24. At this time, the unblocking brush 21 is limited again. With this setting, when the screening holes on the surface of the screening plate 3 are blocked by materials, they can be unblocked in time to avoid material accumulation, thereby ensuring the smooth progress of the screening process, improving screening efficiency, and ensuring screening quality.

[0034] Reference Figure 4 As shown in this embodiment: a fourth spring 25 is slidably connected to the surface of the limiting rod 23, a second circular plate 26 is fixedly connected to the bottom end of the limiting rod 23, the bottom end of the fourth spring 25 is fixedly connected to the second circular plate 26, and the top end of the fourth spring 25 is fixedly connected to the top end inside the second circular groove 22. By setting the fourth spring 25, the elasticity of the fourth spring 25 abuts against the second circular plate 26, thereby restricting the movement of the limiting rod 23 and preventing the limiting rod 23 from coming out of the limiting groove 24.

[0035] Working principle: By pressing the first circular plate 10, the first circular plate 10 drives the circular rod 8 and the push block 9 to move into the irregular groove 7. This causes the push block 9 to push the connecting block 6 out of the irregular groove 7, thus releasing the limiting position between the raisin screening device body 1 and the screening plate 3. The screening plate 3 can then be quickly removed from the raisin screening device body 1. During installation, pressing the connecting block 6 retracts it into the first circular groove 4, resetting the screening plate 3. The elasticity of the first spring 5 automatically pushes the connecting block 6 into the irregular groove 7. The sieving plate 3 is reconnected to the main body 1 of the raisin screening device by the groove 7. This allows the sieving plate 3 to be quickly removed from the main body 1 for replacement. Different sieving plates with different apertures can be used for different screening needs and different types of raisins, improving the flexibility of screening. The snap-fit ​​groove 11 and the first circular plate 10 are connected, and when the sieving plate 3 is installed inside the main body 1 of the raisin screening device, the snap-fit ​​groove 11 and the first circular plate 10 form a snap-fit. This design facilitates the installation of the sieving plate 3.

[0036] The positioning effect at the time makes the connection between the screening plate 3 and the main body 1 of the raisin screening device more stable, avoiding sliding displacement. By setting the second spring 13, the displacement of the round rod 8 and the push block 9 can be limited. The elasticity of the second spring 13 abuts against the first round plate 10, preventing the round rod 8 from driving the push block 9 to move when the equipment vibrates during operation. By allowing the sliding block 15 to slide inside the sliding groove 14, the movement of the round rod 8 can be given linear guidance, making the movement of the round rod 8 more stable and ensuring that the round rod 8 moves along the predetermined path without tilting or shaking. By setting the limiting plate 16, it can be ensured that one side of the connecting block 6 remains inside the first round groove 4 and will not come out of the first round groove 4 due to the elasticity of the first spring 5, ensuring the raisin The stability of the connection between the main body 1 of the screening device and the screening plate 3 is ensured by raising the limiting rod 23, causing one end of the limiting rod 23 to disengage from the limiting groove 24. At this time, the limiting position of the unblocking brush 21 is released. Then, the unblocking brush 21 is pressed down, so that the bottom end of the unblocking brush 21 contacts the top end of the screening plate 3. The unblocking brush 21 is moved to clean the surface of the screening plate 3. After use, the unblocking brush 21 is reset, and the limiting rod 23 is pulled back, causing one end of the limiting rod 23 to return to the limiting groove 24. At this time, the unblocking brush 21 is again limited. Through this setting, when the screening holes on the surface of the screening plate 3 are blocked by material, they can be unblocked in time, avoiding material accumulation, thereby ensuring the smooth progress of the screening process, improving screening efficiency, and ensuring screening quality. A fourth spring 25 is also included.

[0037] The elasticity of the fourth spring 25 abuts against the second circular plate 26, thereby restricting the movement of the limiting rod 23 and preventing the limiting rod 23 from coming out of the limiting groove 24.
