Description

Technical Field

[0001] This utility model relates to the field of braised food production technology, and in particular to a shaking screening device. Background Technology

[0002] In the production of braised products, the purity and consistency of materials must be ensured at every stage, from raw material processing to finished product packaging. Effective sieving of braised products is one of the key steps in improving product quality. Vibrating sieving equipment (used in braised product production) is an important piece of equipment in the braised product processing line. It is mainly used to separate impurities and grade materials before and after braising. Its performance directly affects the efficiency of subsequent processing and the quality of the final product, playing an irreplaceable role in large-scale braised product production.

[0003] In existing technologies, equipment used for screening braised products mostly employs a vibrating screen structure. Its technical principle involves a motor driving an eccentric block to rotate at high speed, generating centrifugal force that causes the screen body to vibrate with a certain amplitude. Material enters from one end of the screen body and moves along the screen surface under the vibration. Material smaller than the screen openings passes through the screen surface and falls into the collection device below, while material larger than the openings is discharged from the other end of the screen body, thus achieving material screening. In addition, some equipment also incorporates manual sorting to remove impurities from the material, supplementing the shortcomings of mechanical screening.

[0004] However, existing screening equipment often suffers from incomplete separation of strip-shaped impurities during the pretreatment of braised products. Due to the unstable movement path of the material on the screen surface, some strip-shaped impurities easily mix with other materials, making them difficult to effectively block and separate. As a result, a certain amount of strip-shaped impurities remain in the pretreated braised products, affecting the smooth progress of subsequent processing. Summary of the Invention

[0005] To overcome the above shortcomings, this utility model provides a shaking screening device, which aims to improve the problem that existing screening devices often fail to completely separate strip-shaped impurities when pre-treating braised products.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a shaking screening device, including a fixed support, a screening chamber fixedly connected to the upper surface of the fixed support, a multi-stage screening plate slidably connected to the inner wall of the screening chamber, a guide plate fixedly connected to the bottom of the screening chamber, a plurality of conveying plates fixedly connected to the outer wall of the screening chamber, a sorting chamber fixedly connected to one end of the screening chamber, a primary feeding plate fixedly connected to the inside of the screening chamber, a hopper fixedly connected to the top of the primary feeding plate, a sorting plate disposed inside the primary feeding plate, a perforated conveying plate fixedly connected to the upper surface of the primary feeding plate, and a cleaning component disposed at the top of the sorting chamber; The cleaning component includes a collection box that is slidably connected inside the sorting chamber. A hinge is fixedly connected to the top of the sorting chamber, and a chamber door is fixedly connected to one side of the outer wall of the hinge.

[0007] Furthermore, auxiliary wheels are fixedly connected to both sides of the outer wall of the multi-stage screening plate, a guide rail is fixedly connected to the outer wall of the screening chamber, and a shaking component is provided on the upper surface of the screening chamber.

[0008] Furthermore, the shaking assembly includes a motor and a transmission belt. The motor is positioned above the screening chamber, and its output end is connected to one end of the transmission belt. Both ends of the transmission belt are provided with rotating shafts, and arc-shaped gears are fixedly connected to the outer walls of both rotating shafts. A fixed plate is fixedly connected to the upper surface of the screening chamber, and a bidirectional toothed plate is slidably connected inside the fixed plate. The bidirectional toothed plate meshes with the arc-shaped gears, and a top plate is fixedly connected to one end of the bidirectional toothed plate. The bottom of the top plate is fixedly connected to the top of the multi-stage screening plate. The guide plate and the inner wall of the multi-stage screening plate are both designed with a 35° inclination.

[0009] Furthermore, the collection box is disposed below the sorting plate, and the collection box is used to store strip-shaped products.

[0010] Furthermore, the primary feeding plate is located below the hopper, and the inner wall of the primary feeding plate is designed to be inclined at 35°. The primary feeding plate is used to convey the braised products.

[0011] Furthermore, the outer wall of the auxiliary wheel is slidably connected to the inside of the guide rail, which is used to guide the auxiliary wheel.

[0012] Furthermore, the outer walls of both of the arc-shaped gears are rotatably connected to the fixed plate, and the arc-shaped gears are used to drive the bidirectional gear plate to reciprocate.

[0013] Furthermore, the guide plate is disposed below the multi-stage screening plate, and multiple conveying plates are disposed at the openings of the guide plate.

[0014] This utility model has the following beneficial effects: 1. In this utility model, the guiding action of the hopper ensures accurate feeding of braised products, and the 35° inclined surface of the primary feeding plate achieves stable conveying. A progressive screening structure is formed by the sorting plate and the perforated conveying plate. The sorting plate first blocks and guides the strip-shaped products to the collection box for initial collection. The perforated conveying plate further blocks any remaining strip-shaped products, improving the thoroughness of screening. Simultaneously, the door design makes it convenient to remove the strip-shaped products, effectively improving the efficiency of separating strip-shaped impurities in the pre-treatment stage of braised products.

[0015] 2. In this utility model, the pre-treated braised products are accurately conveyed to a multi-stage screening plate. With the help of the linkage structure of motor, transmission belt, rotating shaft, arc gear and bidirectional toothed plate, the multi-stage screening plate is driven to move back and forth, forming a dynamic screening mechanism. This can promote the full dispersion of braised products during the screening process. Combined with the structural features of the multi-stage screening plate, the grading of braised products of different specifications can be completed efficiently. This not only reduces labor costs, but also enhances the stability and accuracy of the grading operation, which helps to improve the overall efficiency of braised product production.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Reference Figures 1-5An embodiment of this utility model provides a shaking screening device, including a fixed support 1, a screening chamber 2 fixedly connected to the upper surface of the fixed support 1, a multi-stage screening plate 4 slidably connected to the inner wall of the screening chamber 2, a guide plate 3 fixedly connected to the bottom of the screening chamber 2, a plurality of conveying plates 5 fixedly connected to the outer wall of the screening chamber 2, a sorting chamber 15 fixedly connected to one end of the screening chamber 2, a primary feeding plate 19 fixedly connected to the inside of the screening chamber 2, a hopper 18 fixedly connected to the top of the primary feeding plate 19, a sorting plate 16 disposed inside the primary feeding plate 19, a perforated conveying plate 17 fixedly connected to the upper surface of the primary feeding plate 19, and a cleaning component disposed on the top of the sorting chamber 15. The cleaning assembly includes a collection box 22, which is slidably connected inside the sorting chamber 15. A hinge 20 is fixedly connected to the top of the sorting chamber 15, and a door 21 is fixedly connected to one side of the outer wall of the hinge 20. The collection box 22 is located below the sorting plate 16 and is used to store strip-shaped products. The primary feeding plate 19 is located below the hopper 18 and has a 35° inclined inner wall. The primary feeding plate 19 is used to transport the braised products.

[0020] Specifically, the braised products are first accurately fed onto the primary feeding plate 19 by the guiding action of the hopper 18. The inner wall of the primary feeding plate 19 is designed with a 35° slope, which effectively promotes the stable conveying of the braised products along the slope to the other end, avoiding accumulation or stagnation during the conveying process. As the braised products are conveyed along the primary feeding plate 19, they pass through the sorting plate 16 in sequence. The sorting plate 16 can block some strip-shaped products mixed in with the braised products, causing the strip-shaped products to fall into the collection box 22 below under the action of their own gravity and conveying force, thereby achieving the initial collection and storage of strip-shaped products and reducing the interference of strip-shaped products with the processing of braised products in subsequent processes. After being sorted by the sorting plate 16, the braised products continue to move along the predetermined conveying path, and then pass through the perforated conveying plate 17 for the next conveying step. The porous conveyor plate 17 not only conveys the braised products, but its special porous structure also further blocks strip-shaped products that have not been completely separated by the sorting plate 16, achieving secondary screening and significantly improving the separation efficiency of strip-shaped products. When the sorting process reaches a certain stage and the collected strip-shaped products need to be removed, the staff can open the top of the sorting chamber 15 through the chamber door 21. This is convenient to operate, facilitates timely cleaning, and ensures the continuous and stable operation of the equipment.

[0021] Reference Figure 1 and Figure 5Auxiliary wheels 6 are fixedly connected to both sides of the outer wall of the multi-stage screening plate 4. A guide rail 14 is fixedly connected to the outer wall of the screening chamber 2. A shaking assembly is provided on the upper surface of the screening chamber 2. The shaking assembly includes a motor 9 and a transmission belt 10. The motor 9 is located above the screening chamber 2, and its output end is connected to one end of the transmission belt 10. Rotating shafts 13 are provided at both ends of the transmission belt 10. Arc-shaped gears 11 are fixedly connected to the outer walls of both rotating shafts 13. A fixed plate 8 is fixedly connected to the upper surface of the screening chamber 2. A bidirectional toothed plate 12 is slidably connected inside the fixed plate 8. The bidirectional toothed plate 12 is meshed with the arc gear 11. One end of the bidirectional toothed plate 12 is fixedly connected to the top plate 7. The bottom of the top plate 7 is fixedly connected to the top of the multi-stage screening plate 4. The guide plate 3 and the inner wall of the multi-stage screening plate 4 are both designed to be inclined at 35°. The outer wall of the auxiliary wheel 6 is slidably connected to the inside of the guide rail 14. The guide rail 14 is used to guide the auxiliary wheel 6. The outer walls of the two arc gears 11 are rotatably connected to the fixed plate 8. The arc gears 11 are used to drive the bidirectional toothed plate 12 to move back and forth. The guide plate 3 is set below the multi-stage screening plate 4. Multiple conveying plates 5 are set at the opening of the guide plate 3.

[0022] Specifically, the pre-treated braised products are precisely conveyed above the multi-stage screening plate 4 and enter the grading and screening stage. Next, the motor 9 is started, and its operation drives the transmission belt 10. During operation, the transmission belt 10 cooperates with the rotating shaft 13, driving the two arc-shaped gears 11 to rotate synchronously. Since the arc-shaped gears 11 mesh with the bidirectional toothed plates 12, the rotation of the arc-shaped gears 11 is converted into the reciprocating movement of the bidirectional toothed plates 12. The bidirectional toothed plates 12 are connected to the top plate 7, and thus, the reciprocating motion of the bidirectional toothed plates 12 drives the top plate 7 and the multi-stage screening plate 4 to reciprocate together. The reciprocating motion of the multi-stage screening plate 4 achieves the grading and screening of braised products of different specifications, meeting the different requirements of subsequent processing for the specifications of braised products, and improving the precision and overall quality of braised product production.

[0023] Working Principle: When the braised food production device is needed, the braised food is first accurately fed to the top of the primary feeding plate 19 by the guiding action of the hopper 18. The inner wall of the primary feeding plate 19 is designed with a 35° slope, which causes the braised food to be stably conveyed to the other end along the slope. During the process of conveying the braised food along the primary feeding plate 19, it will pass through the sorting plate 16 in sequence. This plate can block some strip-shaped products in the braised food, and the strip-shaped products will fall into the collection box 22 below, thus achieving the initial collection and storage of the strip-shaped products. After being sorted by the sorting plate 16, the braised food continues to move along the conveying path, and then passes through the perforated conveyor plate 17 for the next step of conveying. The perforated conveyor plate 17 not only serves to convey the braised food, but also further blocks the strip-shaped products, further achieving screening. When the sorting work has reached a certain stage and it is necessary to remove the strip-shaped products, the operator can open the top of the sorting chamber 15 through the chamber door 21 to conveniently remove the strip-shaped products inside. Furthermore, the pre-treated braised products are precisely conveyed above the multi-stage screening plate 4. Next, the motor 9 is started, and its operation drives the transmission belt 10. During operation, the transmission belt 10, in conjunction with the rotating shaft 13, drives the two arc-shaped gears 11 to rotate synchronously. Since the arc-shaped gears 11 mesh with the bidirectional toothed plate 12, the rotation of the arc-shaped gears 11 drives the bidirectional toothed plate 12 to reciprocate. The bidirectional toothed plate 12 is connected to the top plate 7, and thus, the reciprocating motion of the bidirectional toothed plate 12 drives the top plate 7 and the multi-stage screening plate 4 to reciprocate together.

Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
