Description

Technical Field

[0001] This utility model relates to the field of food processing technology, specifically to a vibrating screen for food processing with quantitative feeding. Background Technology

[0002] Food processing refers to the processing of grains, feeds, vegetable oils and sugars, slaughtering and meats, aquatic products, and vegetables, fruits and nuts, directly using agricultural, forestry, animal husbandry and fishery products as raw materials. In the process of processing some food raw materials, screening is required so that the food can be used better in subsequent applications.

[0003] During the screening process of food raw materials, the application areas of the raw materials are allocated according to the size of the screening results. Therefore, the raw materials need to be screened carefully. A single screening process is slow and the screening efficiency is not high.

[0004] To overcome the above-mentioned defects, prior art 1 (Chinese patent publication number: CN107694742B, publication date: 2019-07-23) discloses a walnut screening machine, comprising an outer casing and an inner casing with an open top. The outer casing includes a top plate and a bottom plate. The top plate has an air inlet, and the bottom plate has a water outlet with a valve. The inner casing is located inside the outer casing. A rotating shaft is connected to the bottom of the inner casing, and the rotating shaft passes through the bottom plate and is connected to a motor. Several drainage holes are evenly distributed on the inner casing. A flip-top door that can be rotated to the outside of the inner casing is movably connected to the inner wall of the inner casing. A screening cylinder passing through the flip-top door is provided inside the inner casing. The screening cylinder is vertically arranged, and a bearing is connected between one side of the screening cylinder and the bottom of the inner casing. The top of the screening cylinder is open, and the screening cylinder has several sieve holes. The screening machine can complete the cleaning, impurity removal, screening, and drying of walnuts, resulting in high walnut processing efficiency.

[0005] There is also prior art 2 (Chinese patent publication number: CN118513233A, publication date: 2024-08-20) which describes a breadcrumb sieving machine, relating to the field of food processing technology. It includes a uniform feeding box and a conveying mechanism. A dust collection box is located at the bottom of the uniform feeding box, and a sieving box is located at the bottom of the dust collection box. A first screening cylinder is rotatably connected inside the uniform feeding box. A first driving component is connected to one side of the first screening cylinder, driving the first screening cylinder to rotate. A first inclined plate and a second inclined plate are located at the top of the first screening cylinder. The design incorporates a combination of a drum-type first screening cylinder, a second screening cylinder, and a wind-type dust collection box. This combination of drum and wind-type screening methods allows for more stable, uniform, and fine screening of breadcrumbs, reducing surface damage and improving both quality and yield. Simultaneously, the wind-type dust collection box effectively removes dust generated during the screening process.

[0006] While existing technologies 1 and 2 can perform multiple screenings of raw materials and improve screening efficiency, their devices cannot perform indirect quantitative feeding. If the raw materials are directly fed into the screening process, incomplete screening may occur.

[0007] Therefore, we propose a quantitative feeding vibrating screen for food processing raw materials to solve the problems mentioned above. Utility Model Content

[0008] The purpose of this invention is to provide a vibrating screen for food processing with quantitative feeding, in order to solve the problem mentioned in the background art that indirect quantitative feeding is not possible and raw materials are directly fed into the screen, which may result in incomplete screening.

[0009] To achieve the above objectives, the present invention provides the following technical solution: a quantitative feeding food processing raw material vibrating screen, comprising a shell, a feeding barrel being provided through the upper surface of the shell, a collection box being fixedly connected to the lower side of the shell, and a fixing rod being fixedly connected to the upper side of the collection box.

[0010] A baffle is nested inside the upper surface of the housing, and a bidirectional lead screw is nested inside the upper side of the housing. A first motor is fixedly connected to the outer end of the bidirectional lead screw. A discharge mechanism for indirect quantitative feeding is provided on the outer side of the bidirectional lead screw and the lower side of the baffle.

[0011] The upper surface of the collection box is nested with a second screening box, and the lower surface of the collection box is fixedly connected with a second motor. The output end of the second motor is fixedly connected with a rotating plate. A swing mechanism that can drive the second screening box to perform secondary screening is provided between the rotating plate and the side of the second screening box.

[0012] Furthermore, a first screening box is fixedly connected to the outside of the fixed rod, and a vibrator is fixedly connected inside the first screening box.

[0013] Furthermore, the first screening box is located above the second screening box, and the diameter of the sieve holes in the first screening box is larger than the diameter of the sieve holes in the second screening box.

[0014] Furthermore, the discharge mechanism includes a limiting rod, which is fixedly connected to the upper inner side of the housing, and an adjusting plate is nested on the outer side of the limiting rod. The lower side of the adjusting plate is threadedly connected to the outer side of the bidirectional lead screw, and a pull rod is hinged between the inner side of the adjusting plate and the outer side of the baffle.

[0015] Furthermore, the baffle is connected to the housing via a pull rod to form a sliding structure, and the adjusting plate is connected to the limiting rod via a two-way lead screw to form a sliding mechanism. The baffle is symmetrically arranged about the center point of the feed hopper.

[0016] Furthermore, the swing mechanism includes a connecting rod, which is fixedly connected to the lower inner side of the housing, and a movable plate is nested on the outer side of the connecting rod. Springs are fixedly connected between the left and right sides of the movable plate and the inner wall of the housing. A connecting rod is fixedly connected to the front and rear sides of the movable plate, and the upper end of the connecting rod is fixedly connected to the side of the second screening box. A linkage plate is hinged between the edge of the rotating plate and the linkage plate.

[0017] Furthermore, the connecting rod drives the second screening box and the collection box to form a sliding structure through the linkage plate, and the moving plate forms an elastic structure with the shell through the spring.

[0018] Compared with the prior art, the beneficial effects of this utility model are:

[0019] 1. Staff can put food ingredients into the device through the feeding bucket. The ingredients fall into the first screening box. The vibrator is then activated, causing the first screening box to vibrate, thereby performing preliminary screening of the ingredients.

[0020] 2. The screened raw materials fall into the second screening box, where they are screened a second time. The screened raw materials fall into the collection box. This device allows for a second screening of the raw materials, making the screening process more refined.

[0021] 3. Start the second motor. The second motor drives the rotating plate to rotate and pulls the linkage plate through the rotating plate. Under the pull of the rotating plate, the linkage plate causes the moving plate to move along the connecting rod. The moving plate drives the second screening box to move back and forth along the second screening box through the docking rod, thereby performing screening operations on the raw materials and further improving the screening efficiency of the raw materials.

[0022] 4. After the raw materials are put into the feeding hopper, the first motor is started. At this time, the first motor drives the double-sided lead screw to rotate. The adjusting plate begins to move laterally under the drive of the double-sided lead screw thread, thereby synchronously driving the pull rod to rotate and driving the baffle to move back and forth, indirectly blocking the feeding hopper, thereby realizing indirect quantitative feeding and reducing the phenomenon of raw material accumulation and uneven screening caused by direct feeding.

[0023] 5. During the movement of the adjusting plate, it will move synchronously along the limiting rod, thereby enabling the pull rod to better drive the baffle to move, and enabling the baffle to better control the feeding of raw materials. Attached Figure Description

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.

[0032] Example 1: As Figure 1 and Figure 2 The technical solution shown herein provides the following technical solution: a quantitative feeding vibrating screen for food processing raw materials, which discloses a first screening box 4, through which the raw materials can be initially screened:

[0034] The first screening box 4 is fixedly connected to the outside of the fixed rod 6, and the vibrator 7 is fixedly connected inside the first screening box 4. The first screening box 4 is located above the second screening box 5, and the diameter of the screen hole of the first screening box 4 is larger than the diameter of the screen hole of the second screening box 5.

[0035] Workers can feed food ingredients into the device through the feed hopper 2. The ingredients fall into the first screening box 4. The vibrator 7 is then activated, causing the first screening box 4 to vibrate, thus performing preliminary screening of the ingredients.

[0036] Example 2: Figure 2 , Figure 5 and Figure 6 The technical solution shown herein provides the following solution: a quantitative feeding vibrating screen for food processing raw materials, which discloses a discharge mechanism. This discharge mechanism allows for the indirect discharge of raw materials, reducing the possibility of excessive material input and incomplete screening.

[0037] A baffle 14 is nested inside the upper surface of the housing 1, and a bidirectional lead screw 10 is nested inside the upper side of the housing 1. A first motor 8 is fixedly connected to the outer end of the bidirectional lead screw 10. A discharge mechanism for indirect quantitative feeding is provided on the outer side of the bidirectional lead screw 10 and the lower side of the baffle 14.

[0038] The material discharge mechanism includes a limiting rod 12, which is fixedly connected to the upper side of the inner side of the housing 1. An adjusting plate 11 is nested on the outer side of the limiting rod 12, and the lower side of the adjusting plate 11 is threadedly connected to the outer side of the bidirectional lead screw 10. A pull rod 13 is hinged between the inner side of the adjusting plate 11 and the outer side of the baffle 14.

[0039] The baffle 14 forms a sliding structure with the housing 1 via the pull rod 13, and the adjusting plate 11 forms a sliding mechanism with the limiting rod 12 via the bidirectional screw 10. The baffle 14 is symmetrically arranged about the center point of the feed hopper 2.

[0040] After the raw materials are put into the feed hopper 2, the first motor 8 is started. At this time, the first motor 8 drives the bidirectional lead screw 10 to rotate. The adjusting plate 11 starts to move laterally under the drive of the thread of the bidirectional lead screw 10. During the movement, the adjusting plate 11 will move synchronously along the limiting rod 12, thereby synchronously driving the pull rod 13 to rotate and driving the baffle 14 to move back and forth, indirectly blocking the feed hopper 2, thereby realizing indirect quantitative feeding and reducing the phenomenon of raw material accumulation and uneven screening caused by direct feeding.

[0041] Example 3: Figure 2 , Figure 3 and Figure 4 The technical solution shown herein provides the following technical solution: a quantitative feeding food processing raw material vibrating sieve, which discloses a swing mechanism that drives the second sieve box 5 to perform secondary sieve of the raw materials:

[0042] The upper surface of the collection box 3 is nested with a second screening box 5, and the lower surface of the collection box 3 is fixedly connected with a second motor 9. The output end of the second motor 9 is fixedly connected with a rotating plate 19. A swing mechanism that can drive the second screening box 5 to perform secondary screening is provided between the rotating plate 19 and the side of the second screening box 5.

[0043] The swing mechanism includes a connecting rod 15, which is fixedly connected to the lower inner side of the housing 1. A movable plate 17 is nested on the outer side of the connecting rod 15. Springs 16 are fixedly connected between the left and right sides of the movable plate 17 and the inner wall of the housing 1. A connecting rod 18 is fixedly connected to the front and rear sides of the movable plate 17. The upper end of the connecting rod 18 is fixedly connected to the side of the second screening box 5. The side of the rotating plate 19 is hinged to the linkage plate 20. The connecting rod 18 drives the second screening box 5 and the collection box 3 to form a sliding structure through the linkage plate 20. The movable plate 17 forms an elastic structure with the housing 1 through the springs 16.

[0044] The screened raw materials fall into the second screening box 5, where they undergo secondary screening. The screened raw materials then fall into the collection box 3. This device allows for secondary screening of the raw materials, resulting in finer screening. The second motor 9 is then started, causing the rotating plate 19 to rotate. The rotating plate 19 pulls the linkage plate 20, causing the moving plate 17 to move along the connecting rod 15. The moving plate 17, through the connecting rod 18, drives the second screening box 5 to reciprocate, thereby performing screening operations on the raw materials and further improving the screening efficiency.
