Description

Technical Field

[0001] This utility model relates to the field of food processing technology, and in particular to an automatic food sorting device. Background Technology

[0002] Against the backdrop of the booming food processing industry, the scale of food production continues to expand, and the variety of products is becoming increasingly complex. These changes have placed stringent demands on food sorting technology. To solve the problems of manual sorting, automated sorting technology has emerged. Although traditional sorting devices have improved sorting speed to some extent, they have many limitations, as follows: Traditional sorting devices typically use bolts to fix the sorting nets, making it cumbersome and time-consuming to replace parts of the sorting nets, which is difficult to meet the requirements of rapid changeover for small-batch, multi-category production. Furthermore, when processing moist or sticky foods, these sorting devices often experience food accumulation on the net surface and blockage of the mesh, severely affecting sorting efficiency. Although visual recognition sorting devices do not involve sorting mesh structures, they have stringent requirements for lighting conditions. In the complex lighting environment of actual food processing workshops, misjudgments are prone to occur, making it difficult to accurately distinguish between foods with similar particle sizes, resulting in a high sorting error rate. For example, in the sorting of small fruits and vegetables, fruits of similar sizes are easily confused. The aforementioned sorting mesh also suffers from the same defects. Furthermore, visual recognition sorting devices are expensive and require a large installation space, making them unsuitable for small workshops with limited space. Utility Model Content

[0009] Furthermore, a set of receiving slots is provided on the inner side of the positioning housing, and a storage housing is installed inside each receiving slot. The positioning housing, positioning rod, push-pull handle, locking rod, and storage housing cooperate with each other to form a collection assembly, and the sorting net and the storage housings in different positions are aligned.

[0010] Furthermore, a set of connecting plates is provided between the supporting frame and the stabilizing frame, which connect the supporting frame and the stabilizing frame into a whole. A slot is opened on the inner side of the connecting plate. The slot is a hemispherical structure. A set of blocks is provided on the outer side of the bottom of the sorting net. The blocks are hemispherical structures and extend into the inside of the slot.

[0011] Furthermore, a set of support rods is provided on each side of the stabilizing frame. The support rods are cylindrical structures.

[0013] This utility model provides an automatic food sorting device, which has the following beneficial effects: First, the automatic food processing sorting device integrates various functional components through a frame. An electric motor drives the cam to rotate, and with the help of a support spring, the sorting components generate high-frequency micro-amplitude vibrations. A set of sorting nets with different mesh sizes is used to achieve multi-level screening of food. Specifically, the support spring pushes the stable frame and sorting net to reset, and the cam squeeze achieves the effect of the stable frame and sorting net cyclically shaking. By increasing the speed of the electric motor, the sorting net achieves high-frequency micro-amplitude vibration, which effectively prevents food particles from clogging the mesh and improves sorting efficiency. The shaking gravity accelerates the sorting of food and avoids food accumulation on the mesh surface, making it suitable for sorting moist and sticky foods. Specifically, the sorting net can be flexibly replaced with the model required.

[0014] Secondly, the collection components can be quickly unlocked and replaced through the cooperation of the push-pull handle and the locking lever, ensuring that food of different particle sizes falls accurately into the corresponding storage shell after sorting; Specifically, food items of the same particle size fall into the corresponding storage shell. The storage shell collects different food items and impurities after being sorted by the sorting net, reducing manual sorting costs and improving food sorting efficiency, especially suitable for sorting small-particle-size food items. Specifically, by pressing down on the push-pull handle to disengage the locking lever from the frame, the collection component can be quickly unlocked; after releasing the handle, the spring returns and quickly locks the collection component inside the frame. This design reduces the replacement time of the collection component to a dozen seconds, significantly improving the operation and stability of the collection component compared to the traditional bolt connection method, while ensuring no displacement during the sorting process.

[0015] In addition, the entire device achieves automatic sorting with a purely mechanical structure, and features vibration anti-blocking, multi-level classification, and quick disassembly and maintenance, effectively improving the efficiency and accuracy of food sorting and adapting to the diverse needs of small-batch food processing scenarios.

Detailed Implementation

[0020] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the described embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0021] Example 1: Please refer to Figures 1 to 8 : This utility model proposes an automatic sorting device for food processing, including: a frame 1, with a set of mounting holes on both sides of the bottom of the frame 1, and matching stabilizing bolts installed inside the mounting holes according to actual needs; a horizontal stabilizing plate 101 is provided on one side of the frame 1, and an electric motor 2 is installed at the bottom of the stabilizing plate 101, with matching bolts installed between the stabilizing plate 101 and the electric motor 2, thus stabilizing the electric motor 2; a stabilizing sleeve is provided in the middle of the stabilizing plate 101, and the drive shaft of the electric motor 2 passes through the inside of the stabilizing sleeve; a cam 201 is installed on the outer side of the drive shaft of the electric motor 2, and a keyway is provided at the connection position between the cam 201 and the drive shaft; a horizontal friction plate 405 is provided on one side of the stabilizing frame 401, and the side of the friction plate 405 contacts the side of the cam 201. Specifically, when the electric motor 2 drives the cam 201 to rotate, the eccentric structure of the cam 201 periodically squeezes the friction plate 405, causing the stabilizing frame 401 to move linearly along the support rod 404. In this embodiment, a positioning housing 301 is installed on the inner side of the frame 1. A set of universal wheels is installed at the bottom of the positioning housing 301. Two vertical positioning rods 302 are provided on one side of the positioning housing 301. The positioning rods 302 are cylindrical. A vertical push-pull handle 303 is installed between the two positioning rods 302. Two sliding holes are opened at the bottom of the push-pull handle 303. The positioning rods 302 pass through the interior of the sliding holes. A support spring is installed on the outer side of the positioning rods 302. The support spring elastically supports the push-pull handle 303 upwards. With the cooperation of the positioning rods 302, the positioning housing 301 and the push-pull handle 303 are movably connected. In addition, the push-pull handle 303 can move up and down with the sliding holes. The bottom of the push-pull handle 303 is located at the two... A vertical locking rod 304 is provided on each side. A vertical sliding hole is opened on the upper position of each side of the frame 1. The locking rod 304 passes through the inside of the sliding hole. With the cooperation of the sliding hole and the locking rod 304, the collection component 3 is quickly locked inside the frame 1. The collection component 3 can be unlocked by pressing down the push-pull handle 303. By pressing down the push-pull handle 303 to compress the support spring, the locking rod 304 is disengaged from the sliding hole of the frame 1, and the collection component 3 can be quickly unlocked. After releasing, the spring rebounds to realize the automatic locking of the collection component 3. This design reduces the replacement time of the collection component 3 to more than ten seconds. Compared with the traditional bolt connection method, the operation and stable portability of the collection component 3 are greatly improved, while ensuring no displacement during the sorting process. In this embodiment, a set of receiving grooves is provided on the inner side of the positioning housing 301, and a storage housing 305 is installed inside each receiving groove. The positioning housing 301, positioning rod 302, push-pull handle 303, locking rod 304, and storage housing 305 cooperate with each other to form the collection assembly 3. The receiving grooves hide and position the installation position of the storage housing 305. The sorting net 403 and the storage housing 305 at different positions are aligned. Specifically, food of different particle sizes falls into the corresponding storage housing 305. The storage housing 305 collects the different food and impurities after sorting by the sorting net 403, reducing the cost of manual sorting and improving the sorting efficiency of food, especially suitable for sorting small particle size food. In this embodiment, a movably connected sturdy frame 401 is installed at the top of the frame 1. A set of support frames 402 is located at the bottom of the sturdy frame 401. The support frames 402 have a U-shaped structure. A set of mounting holes corresponding to the support frames 402 are opened on the inner side of the sturdy frame 401. A set of sorting nets 403 are installed inside the mounting holes. The mesh size of each set of sorting nets 403 is different. The bottom of the sorting nets 403 contacts the top of the support frames 402. The support frames 402 position and support the installation of the sorting nets 403. The mounting holes facilitate the installation and replacement of the sorting nets 403. Different sorting nets 403 are used to automatically screen food of different particle sizes and impurities. A connecting plate is provided between the support frames 402 and the sturdy frame 401, connecting the support frames 402 and the sturdy frame 401. The components 401 are connected as a whole. A slot is opened on the inner side of the connecting plate. The slot is hemispherical. A set of blocks is provided on the outer side of the bottom of the sorting net 403. The blocks are hemispherical and extend into the inside of the slot. The cooperation between the hemispherical slot and the blocks achieves the effect of locking the installation position of the sorting net 403. A set of support rods 404 are provided on both sides of the stabilizing frame 401. The support rods 404 are cylindrical. The support rods 404 can also be set as rectangular structures according to actual needs. The stabilizing frame 401, the support frame 402, the sorting net 403, the support rods 404, and the friction plate 405 cooperate with each other to form the sorting component 4. A set of sliding holes are opened on both sides at the top of the frame 1. The sliding holes are oval holes. The support rods 404 pass through the inside of the sliding holes. The sliding holes provide lateral sliding space for the sorting component 4. In this embodiment, a threaded connecting sleeve is provided at the corner of the frame 1. The threaded connecting sleeve is located above the frame 1. A horizontal positioning bolt 5 is installed at the position of the threaded connecting sleeve. The thread pitch is processed according to actual needs to effectively lock the installation position of the positioning bolt 5 on the threaded connecting sleeve. A horizontal sliding hole is opened on one side of the support rod 404. The positioning bolt 5 passes through the interior of the sliding hole. A support spring is installed on the outside of the positioning bolt 5. The support spring pushes the stabilizing frame 401 and the sorting net 403 to reset. Combined with the squeezing of the cam 201, the stabilizing frame 401 and the sorting net 403 achieve the effect of cyclic shaking. By increasing the speed of the electric motor 2, the sorting net 403 achieves high-frequency micro-amplitude vibration, which effectively prevents food particles from clogging the mesh and improves sorting efficiency. The shaking gravity accelerates the sorting of food and avoids food accumulation on the mesh surface, which is suitable for sorting moist and sticky foods.

[0022] Example 2, based on Example 1, such as Figures 1-6 As shown, a commonly used food conveyor needs to be set up. The conveyor is a conventional belt conveyor mechanism. The sorting device is installed on one side of the conveyor along with the frame 1. The food falls evenly and stably above the sorting net 403. The height difference between the conveyor and the sorting net 403 is controlled at about ten centimeters to avoid the problem of food accumulation and spillage when manually loading the food.

[0023] The working principle of this embodiment: Secure the device to the worktable using sturdy bolts through the mounting holes at the bottom of frame 1. According to the particle size of the food to be sorted, select sorting nets 403 with different mesh sizes, embed the sorting nets 403 into the mounting holes of the stable frame 401, use the U-shaped structure of the support frame 402 to support the net surface, and position the sorting nets 403 by engaging with the slots of the hemispherical blocks. Adjust the screw-in depth of the positioning bolt 5 to change the preload of the support spring. For example, increase the preload for nuts to increase the amplitude, and decrease the preload for pastries to avoid breakage. Press the push-pull handle 303, hold the push-pull handle 303 and use the universal wheel to move the collection component 3 to the inside of the frame 1. Stop pressing the push-pull handle 303 and it will spring back under the support of the spring. The locking rod 304 will automatically engage into the corresponding sliding hole to complete the quick locking of the collection component 3. Align the discharge end of the conventional belt conveyor with the inlet of the sorting net 403, adjust the height difference between the conveyor and the sorting net 403 as needed, start the conveyor, and spread the food evenly on the surface of the sorting net 403. When the electric motor 2 is started, the cam 201 rotates with the drive shaft, periodically squeezing the friction plate 405, causing the stable frame 401 to vibrate back and forth along the oval hole, and the sorting net 403 to shake synchronously at high frequency. Under the influence of vibration inertia and gravity, food particles smaller than the mesh size fall into the corresponding storage shell 305; larger food particles are conveyed backward with the vibration of the mesh surface and are further screened by the next level of sorting mesh 403 with different mesh sizes, ultimately achieving the effect of multi-level classification, precise collection and automatic sorting of food. Large-sized food or impurities are discharged from the end of sorting mesh 403 and collected in the corresponding storage shell 305. After the food sorting is completed, press the push-pull handle 303 to unlock the collection component 3, move the collection component 3 to the appropriate position, and pull out the storage shell 305 to unload the material directly. Disassemble the sorting net 403 and storage shell 305, rinse with clean water or food-grade detergent, air dry naturally, and then reassemble. Check the elasticity of the support springs and the wear of the cam 201 monthly, and add lubricating oil to the drive shaft of the electric motor 2 to ensure the long-term stable operation of the vibration system.
